Microplastics and nanoplastics are found in the air, water, and food, leading to concerns about how they enter our bodies and the potential health risks they pose

Plastic pollution is a widespread environmental issue with extensive consequences. An emerging aspect of this problem is the increasing presence of microplastics and nanoplastics in our environment, which may impact human health. These small plastic particles, measuring less than 5 millimetres in size, are found in the air, water, and food, leading to concerns about how they enter our bodies and the potential health risks they pose.

Exposure routes

Research has identified three major routes through which microplastics and nanoplastics can enter the human body: Ingestion, inhalation and dermal contact.

  1. Ingestion

Ingestion, or oral consumption, is a primary route for exposure to microplastics and nanoplastics. These particles have been detected in various food and water sources, including drinking water, seafood, salt, bottled water, and even tea and coffee. Studies have found microplastics in fish, mussels, salts from lakes and oceans, as well as in commercial salts and bottled water. 

Polyethylene terephthalate (PET) and polypropylene (PP) are among the most commonly reported polymers in bottled water. Additionally, tap water has been found to contain microplastics in both developed and developing countries. Even seemingly innocuous items like teabags, coffee, and food products have been found to contain microplastics, illustrating the pervasive nature of this contamination

  1. Inhalation

Inhalation, or breathing, is another significant route of exposure to MPs and NPs. These particles have been detected in the ambient air, with outdoor and indoor concentrations varying depending on location and environmental factors. 

Sources of airborne microplastics include synthetic textiles, industrial emissions, solid waste dumping sites, and agricultural activities. Sea breeze and sea spray near coastal areas also contribute to atmospheric microplastic pollution. 

Inhalation of microplastics may lead to their accumulation in the respiratory tract and potential translocation across the blood-brain barrier, raising concerns about respiratory and neurological health effects.

  1. Dermal Contact

Dermal contact, or skin exposure, is another route through which individuals may be exposed to microplastics and nanoplastics. Consumer products such as face creams, face washes, and cosmetics can contain microplastics, increasing the risk of dermal exposure. 

While absorption through the skin is unlikely due to the physicochemical properties of microplastics, deposition on the skin and potential absorption of nanoparticles raise concerns about skin exposure. Studies have suggested that microfibers and particles from cosmetics and toothpaste may be absorbed by the skin, indicating a need for further investigation into their potential health effects.

Potential health risks

Research on the potential health risks associated with exposure to microplastics and nanoplastics is ongoing, with findings indicating a range of adverse effects on human health. Here are some key areas of concern:

  1. Gastrointestinal and urinary tract system

Exposure to microplastics and nanoplastics via ingestion can lead to their translocation through the gastrointestinal tract and potential accumulation in tissues. Studies have shown that these particles may cause oxidative stress, inflammation, and histological changes in the intestines of animals. 

Furthermore, exposure to microplastics has been associated with immune system dysregulation and metabolic disorders, raising concerns about their long-term health effects.

  1. Respiratory tract system

Inhalation of microplastics and nanoplastics can lead to their accumulation in the respiratory tract, potentially causing irritation, inflammation, and oxidative stress. Research suggests that exposure to these particles may worsen respiratory symptoms and contribute to the development of respiratory disorders. 

Additionally, the size and concentration of microplastics can affect their toxicological impact on lung cells, emphasising the need for further research into respiratory health risks.

  1. Blood and immune system

Exposure to microplastics and nanoplastics has been shown to affect immune cell function and cytokine production in animal studies. Changes in serum levels and immune cell activity have been observed following exposure to these particles, suggesting potential systemic effects. 

Furthermore, the presence of microplastics in lymph nodes and blood circulation raises concerns about their long-term impact on immune function and overall health.

  1. Brain and nervous system

Studies have suggested that microplastics and nanoplastics may have neurotoxic effects, leading to oxidative stress, cytotoxicity, and changes in neurotransmitter levels. 

Exposure to these particles has been linked to cellular damage and inflammation in brain tissue, raising concerns about their potential role in the development of neurological disorders. Moreover, the ability of nanoparticles to cross the blood-brain barrier underscores the need for further research into their neurotoxic effects.

  1. Embryos and placental barrier

The presence of microplastics in the placenta and foetal tissues raises concerns about their potential impact on foetal development and pregnancy outcomes. Studies have shown that microplastics can cross the placental barrier and accumulate in foetal tissues, potentially leading to developmental abnormalities and embryotoxicity. 

Additionally, exposure to microplastics during pregnancy may have long-term implications for the health of both the mother and the developing foetus, highlighting the need for further research in this area.

A review on microplastics and nanoplastics in the environment: Their occurrence, exposure routes, toxic studies, and potential effects on human health. Marine Pollution Bulletin Volume 181, August 2022, 113832

 

The presence of microplastics and nanoplastics in our environment, along with their potential impact on human health, is a matter of increasing concern. Although ongoing research is providing more information on the health effects of these particles, evidence suggests that exposure to microplastics and nanoplastics could pose significant risks to various organ systems and physiological processes within the human body. 

It is crucial to continue efforts to understand the sources, pathways, and health implications of microplastics and nanoplastics to develop effective mitigation strategies and protect public health.

Addressing this issue requires a comprehensive approach that includes reducing plastic waste at its source, improving waste management practices, and finding innovative solutions for the removal of microplastics from the environment. 

By raising awareness, implementing robust policies, and adopting sustainable practices, we can mitigate the threats posed by microplastic contamination and ensure the well-being of future generations.

  • Expects two more Phase 3 readouts in 2024, including combination vaccine against flu and COVID-19, and vaccine against CMV
  • Announces positive clinical trial data from three new vaccines against viruses that cause significant burden (Epstein-Barr virus, Varicella-Zoster virus, norovirus) and advances programs toward Phase 3 development
  • Anticipates U.S. launch of vaccine against RSV following FDA approval and ACIP recommendation in 2024
  • Announces development and commercialization funding agreement with Blackstone Life Sciences for up to $750 million to advance flu program

CAMBRIDGE, MA / ACCESSWIRE / March 27, 2024 / Moderna, Inc. (NASDAQ:MRNA) today announced at its fifth Vaccines Day event clinical and program updates demonstrating advancement and acceleration of its mRNA pipeline. The updates include data readouts in the Company's respiratory and latent and other vaccine portfolios, as well as commercial, manufacturing and financial announcements for its vaccines business.

"Our mRNA platform continues a remarkable track record across our broad vaccine portfolio. Today, we are excited to share that four vaccines in our pipeline have achieved successful clinical readouts across our respiratory, latent and other virus franchises," said Stéphane Bancel, Chief Executive Officer of Moderna. "With five vaccines in Phase 3, and three more moving toward Phase 3, we have built a very large and diverse portfolio addressing significant unmet medical needs. We are focused on execution to further build momentum across our pipeline and business, and to deliver for patients who are impacted by these infectious diseases."

Portfolio Overview

The vaccine portfolio seeks to address infectious diseases that cause considerable health burdens and includes 28 vaccines addressing respiratory, latent and other pathogens.

Latent and Other Vaccine Portfolio

Moderna is advancing five vaccine candidates against viruses that cause latent infections, all of which are in clinical trials. When latent, a virus is present in the body but exists in a resting state, typically without causing any noticeable symptoms. Latent viruses can reactivate and cause clinical symptoms as a person ages, during times of stress or when immunity is compromised. The capacity for latency is a defining feature of members of the Herpesviridae family, including cytomegalovirus (CMV), Epstein-Barr virus (EBV), herpes simplex virus (HSV) and Varicella-Zoster virus (VZV).

Cytomegalovirus (CMV)

CMV is the most common infectious cause of birth defects in the U.S. and is responsible for several billion dollars in annual healthcare costs. One in 200 babies in the U.S. are born with a congenital CMV infection, and of those affected, one in five will have severe, life-altering health problems. Possible short- and long-term sequelae of CMV infection include microcephaly, chorioretinitis, seizures, sensorineural hearing loss, cognitive impairment and cerebral palsy. There is currently no approved vaccine to prevent congenital CMV.

CMVictory is a pivotal Phase 3 trial evaluating mRNA-1647 against primary CMV infection in women 16 to 40 years of age. The trial is a randomized, observer-blind, placebo-controlled study designed to evaluate the efficacy, safety and immunogenicity of mRNA-1647. The trial is fully enrolled with approximately 7,300 participants from 290 clinical sites globally.

To date, 50 primary infection cases have accrued and are undergoing confirmation. The first interim analysis for the evaluation of vaccine efficacy, which will be triggered when both 81 confirmed per-protocol cases and 12 median months of safety follow-up have occurred, is expected as early as the end of 2024.

Moderna's CMV vaccine candidate mRNA-1647 has advanced to indication expansion studies in adolescents 9 to 15 years of age and adult transplant patients, both of which have begun enrollment.

Epstein-Barr virus (EBV)

EBV is a major cause of infectious mononucleosis (IM) in the U.S., accounting for more than 90% of IM cases annually. Importantly, EBV and IM are associated with a higher lifetime risk of more serious sequelae including certain cancers such as gastric carcinoma, nasopharyngeal carcinoma and multiple types of lymphoma. The lifetime risk of developing multiple sclerosis (MS) is increased by 32-fold after EBV infection. There is currently no approved vaccine to prevent EBV.

Moderna's EBV vaccine candidates are designed to tackle multiple EBV-associated conditions, including prevention of IM (mRNA-1189) and MS and post-transplant lymphoproliferative disorder, a subcategory of lymphoma in solid organ transplant patients (mRNA-1195). The Phase 1 trial for mRNA-1189 was designed to test the safety, reactogenicity and immunogenicity of four different dose levels in participants 12 to 30 years of age in the U.S. The randomized, observer-blind, placebo-controlled study showed mRNA-1189 was immunogenic and generally well tolerated across all dose levels. The Company is advancing mRNA-1189 toward a pivotal Phase 3 trial.

The Phase 1 trial for mRNA-1195 was designed to test the safety, reactogenicity and immunogenicity of two drug products at four different dose levels in healthy EBV seropositive participants 18 to 55 years of age in the U.S. The randomized, observer-blind, placebo-controlled study is fully enrolled.

Herpes simplex virus (HSV)

Herpes simplex virus type 2 (HSV-2) infects approximately 13% of adults globally and is the primary cause of genital herpes. There are an estimated four billion people globally infected with HSV, of which 491 million cases are HSV-2. Recurrent genital herpes causes a reduction in quality of life, which antivirals (current standard of care) only partially restore. Moderna expects that if an HSV vaccine candidate could deliver similar efficacy as a suppressive antiviral treatment, compliance with recommended therapy and associated quality of life would improve. There is currently no approved vaccine to treat HSV-2.

The first in human, fully enrolled Phase 1/2 trial of mRNA-1608 is designed to test safety and immunogenicity and to establish a proof-of-concept of clinical benefit in adults 18 to 55 years of age with recurrent HSV-2 genital herpes. The randomized 1:1:1:1, observer-blind, controlled study is fully enrolled with 300 participants in the U.S.

Varicella-Zoster virus (VZV)

Herpes zoster, also known as shingles, is caused by reactivation of latent VZV, the same virus that causes chickenpox. Declining immunity in older adults decreases immunity against VZV, allowing reactivation of the virus from latently infected neurons, causing painful and itchy lesions. Herpes Zoster occurs in one out of three adults in the U.S. in their lifetime and the incidence increases at 50 years of age. There is potential to reach a growing and underserved patient population.

Moderna's VZV vaccine candidate mRNA-1468 has initial data available from a Phase 1/2 trial, which was designed to test safety and immunogenicity in healthy adults 50 years of age and older in the U.S. The randomized 1:1:1:1:1, observer-blind, active-controlled study of mRNA-1468 elicited strong antigen-specific T cell responses at one month after the second dose and was generally well tolerated. Results of the first interim analysis support the further clinical development of mRNA-1468 for the prevention of shingles. Additional results from the ongoing Phase 1/2 study will be available later this year, including persistence data. The Company is planning for a pivotal Phase 3 trial.

Norovirus

Enteric viruses, including norovirus, are a leading cause of diarrheal diseases, resulting in significant morbidity and mortality worldwide, particularly among young children and older adults. Norovirus is highly contagious and a leading cause of diarrheal disease globally, associated with 18% of all acute gastroenteritis (AGE), resulting in approximately 200,000 deaths per year and substantial healthcare costs. Given the wide diversity of norovirus genotypes, a broadly effective norovirus vaccine will require a multivalent vaccine design. There is currently no approved vaccine to prevent norovirus.

The randomized, observer-blind, placebo-controlled Phase 1 trial was designed to evaluate the safety, reactogenicity and immunogenicity of trivalent (mRNA-1403) and pentavalent (mRNA-1405) norovirus vaccine candidates in 664 participants 18 to 49 years of age and 60 to 80 years of age in the U.S. An interim analysis showed that a single dose of mRNA-1403 elicited a robust immune response across all dose levels evaluated with a clinically acceptable reactogenicity and safety profile. The Company is advancing mRNA-1403 toward a pivotal Phase 3 trial.

Respiratory Vaccine Portfolio

Moderna's approach to ease the global burden of respiratory infections includes vaccine candidates against major causative pathogens, including SARS-CoV-2, respiratory syncytial virus (RSV) and influenza virus. Respiratory infections are a top cause of death in the U.S. and are particularly harmful to the young, immunocompromised, and older adults who experience more severe illness, greater incidence of hospitalization, and greater mortality than younger adults.

Moderna's respiratory pipeline includes Phase 3 trials for investigational vaccines including a next-generation COVID-19 vaccine, an RSV vaccine, a flu vaccine, and a flu and COVID-19 combination vaccine. The pipeline includes three additional flu vaccine candidates with expanded antigen coverage as well as combination vaccine programs.

COVID-19

Moderna continues to address the needs of the endemic COVID-19 market by focusing on public health efforts to increase vaccination coverage rates to reduce the substantial burden of COVID-19 as well as by advancing next-generation vaccines. The Company's mRNA platform can produce variant-matched vaccines on an accelerated time horizon, consistent with recent U.S. Food and Drug Administration (FDA) comments on the timing of potential strain selection for the fall booster season.

A recent announcement of positive interim results from the NEXTCove Phase 3 trial showed that mRNA-1283 elicited a higher immune response against both the Omicron BA.4/BA.5 and original virus strains of SARS-CoV-2 compared to mRNA-1273.222, Moderna's licensed COVID-19 vaccine. mRNA-1283 is designed to be refrigerator-stable and paves the way for a combination vaccine against influenza and COVID-19, mRNA-1083, enhancing the Company's overall respiratory portfolio. This is Moderna's fourth infectious disease vaccine program with Phase 3 data.

Respiratory Syncytial Virus (RSV)

RSV is the leading cause of respiratory illness in young children, and older adults are at increased risk relative to younger adults for severe outcomes. In addition to acute mortality and morbidity, RSV infection is associated with long-term sequelae such as asthma and impaired lung function in pediatric populations, and exacerbation of chronic obstructive pulmonary disease in older adults. Annually, there are approximately two million medically attended RSV infections and 58,000 to 80,000 hospitalizations in children younger than five years old in the U.S. In the U.S., each year there are up to 160,000 hospitalizations and 10,000 deaths in adults 65 years and older due to RSV. Across high-income countries in 2019, RSV caused an estimated 5.2 million cases, 470,000 hospitalizations and 33,000 in-hospital deaths in adults 60 years and older.

mRNA-1345

Moderna's RSV vaccine candidate, mRNA-1345, is in an ongoing Phase 2/3, randomized, observer-blind, placebo-controlled case-driven trial (ConquerRSV) in adults over 60 years of age. In this study, approximately 37,000 participants from 22 countries were randomized 1:1 to receive one dose of mRNA-1345 or placebo.

Based on positive data from the ConquerRSV trial, Moderna has filed for regulatory approvals for mRNA-1345 for the prevention of RSV-associated lower respiratory tract disease (RSV-LRTD) and acute respiratory disease (ARD) in adults over 60 years of age.

The trial met both its primary efficacy endpoints, with a vaccine efficacy (VE) of 83.7% (95.88% CI: 66.1%, 92.2%; p<0.0001) against RSV-LRTD as defined by two or more symptoms, and a VE of 82.4% (96.36% CI: 34.8%, 95.3%; p=0.0078) against RSV-LRTD defined by three or more symptoms. These data were published in the New England Journal of Medicine in December 2023.

A subsequent analysis from the ConquerRSV study with a longer median follow-up duration of 8.6 months (versus 3.7 months in the primary analysis), with a range of 15 days to 530 days, and including subjects from the Northern and Southern Hemispheres was recently presented at the RSVVW'24 conference. In this supplemental analysis, mRNA-1345 maintained durable efficacy, with sustained VE of 63.3% (95.88% CI: 48.7%, 73.7%) against RSV-LRTD including two or more symptoms. VE was 74.6% (95% CI: 50.7%, 86.9%) against RSV-LRTD with ≥2 symptoms, including shortness of breath and 63.0% (95% CI: 37.3%, 78.2%) against RSV-LRTD including three of more symptoms. The stringent statistical criterion of the study, a lower bound on the 95% CI of >20%, continued to be met for both endpoints.

mRNA-1345 has been granted Breakthrough Therapy designation by the FDA for the prevention of RSV-LRTD in adults over 60 years of age. The Company is awaiting regulatory approvals and the U.S. ACIP recommendation in 2024.

Indication expansion studies for mRNA-1345

mRNA-1345 has the potential to protect all vulnerable populations from RSV. Moderna has initiated multiple Phase 3 expansion studies in adults over 50 years of age to evaluate co-administration and revaccination. Additional trials (Phase 1 - Phase 3) have been initiated for high-risk adults, as well as maternal and pediatric populations. Interim data from these studies could be available as early as 2024.

Influenza (Flu)

Worldwide, influenza leads to 3-5 million severe cases of flu and 290,000-650,000 flu-related respiratory deaths annually. Two main types of influenza viruses (A and B) cause seasonal flu epidemics, and the influenza A viruses lead to most flu-related hospitalization in older adults.

The Company has several seasonal influenza vaccine candidates in clinical development. Moderna's seasonal flu vaccine, mRNA-1010, demonstrated consistently acceptable safety and tolerability across three Phase 3 trials. In the most recent Phase 3 trial (P303), which was designed to test the immunogenicity and safety of an optimized vaccine composition, mRNA-1010 met all immunogenicity primary endpoints, demonstrating higher antibody titers compared to a currently licensed standard-dose flu vaccine. In an older adult extension study of P303, mRNA-1010 is being studied against high dose Fluzone HD®; the trial is fully enrolled. The Company is in ongoing discussions with regulators and intends to file in 2024.

Combination Respiratory Vaccines

Moderna's combination vaccine candidates cover respiratory viruses associated with the largest disease burden in the category. The Phase 3 combination study of the Company's investigational combination vaccine against flu and COVID-19 (mRNA-1083) for adults aged 50 years and older is fully enrolled and data are expected in 2024. mRNA-1083 was granted Fast Track designation by the FDA in May 2023.

Commercial Updates

Respiratory viruses in addition to latent and other viruses represent large unmet or underserved medical needs, and the human and economic costs from these infectious diseases highlight the need for effective vaccines. To help address this need, Moderna expects multiple vaccine product launches in the next few years, each with significant addressable markets.

The 2024 global endemic COVID-19 vaccine market alone is estimated by Moderna to be approximately $10 billion. COVID-19 continues to show a high burden of disease, and while COVID-19 hospitalizations remain high relative to RSV and flu, the risks of Long COVID are also becoming better understood. Moderna is focused on improving education and awareness to increase vaccination rates as Long COVID data suggests even traditionally low-risk groups should be vaccinated. Moderna is also working with health authorities to align the timing of COVID-19 and flu vaccine launches to help improve public health.

For RSV, Moderna estimates the peak annual market to be approximately $10 billion. The Company expects a strong RSV vaccine launch into a large market in 2024. As the only mRNA investigational vaccine with positive Phase 3 data, Moderna's RSV vaccine candidate has a strong profile with consistently strong efficacy across vulnerable and older populations, a well-established safety and tolerability profile, and ease of administration with a ready-to-use, pre-filled syringe formulation, which could relieve some of the burden that falls on pharmacies during the fall vaccination season.

An interim analysis from an ongoing time and motion study evaluating differences in preparation time between a pre-filled syringe (PFS) presentation and vaccines that require reconstitution showed that a PFS presentation could relieve some of the burden that falls on pharmacies during the fall vaccination season. Results from this study suggest that pharmacies may be capable of preparing up to four times as many doses of PFS in an hour compared to vaccines requiring reconstitution.

Moderna estimates flu vaccines represent an approximately $7 billion market in 2024. The market is expected to grow with the rise of more effective vaccines and there is an opportunity to expand the market with next-generation premium flu vaccines as well as combination respiratory vaccines, adding increased value to the health ecosystem.

CMV is expected to be a $2-5 billion annual market. With no vaccine currently on the market and a potential vaccine launch in 2026, Moderna could be the first CMV vaccine in multi-billion-dollar latent vaccine market. In addition, EBV has the potential to address and reduce the burden and cost of EBV infection in multiple populations, while VZV provides the opportunity to enter a large and growing market, which could be $5-6 billion annually. The market for norovirus vaccines is similar to that of rotavirus in pediatrics with opportunity to expand into the adult population, and represents a $3-6 billion annual market.

Moderna's vaccine portfolio targets large addressable markets, with an estimated total addressable market (TAM) of $52 billon for Moderna infectious disease vaccines, which includes a respiratory vaccines TAM of more than $27 billion and a latent and other vaccines TAM of more than $25 billion.

Manufacturing

The Company's manufacturing innovation supports expanding commercialization of a diverse pipeline through efficiency and productivity gains. Its mRNA manufacturing platform enables benefits such as quality, speed, scale and cost efficiency across a footprint that broadly includes the manufacture of plasmid, mRNA, lipid nanoparticles, as well as fill/finish and quality control capabilities.

As the Company continues to build its footprint for the future, it is developing an agile global manufacturing network to meet commercial demand and support its growing pipeline. Pre-clinical through commercial manufacturing occurs at the Moderna Technology Center in Norwood, Massachusetts, which remains central to the Company's network. New facilities being constructed in Australia, Canada and the UK are expected to come online in 2025, and drug product capacity is achieved through a flexible contract manufacturing network. Additionally, the Company has purchased and started build-out of a manufacturing site in Marlborough, Massachusetts, to enable commercial scale of its individualized neoantigen therapy program.

By continuing to pioneer new technologies, including advanced robotics, applying AI and other digital solutions, and driving network and capital efficiency, Moderna's manufacturing network is expected to also drive more predictable cost of sales.

Research and Development Investment Strategy

Today's updates provide further evidence that Moderna's mRNA technology platform is working, and with a rate of success higher than industry standard. Looking ahead, research and development will continue to be the Company's top capital allocation priority.

As Moderna looks to create value through the research and development strategy for its vaccine portfolio, it is taking three prioritization parameters into consideration: pipeline advancement, revenue diversification and risk reduction. As part of its strategy, the funding options Moderna considers are self-funding, project financing and partnerships.

Moderna recently entered into a development and commercialization funding agreement with Blackstone Life Sciences to advance the Company's flu program. As part of the agreement, Blackstone will fund up to $750 million with a return based on cumulative commercial milestones and low-single digit royalties. Moderna expects to recognize the funding as a reduction in research and development expenses and will retain full rights and control of the Company's flu program. This funding does not result in any change to Moderna's 2024 research and development framework of approximately $4.5 billion.

Medical ventilators are advanced air circulation systems engineered to facilitate breathing for a patient unable to do so independently. A variety of medical ventilators are available for use in different medical environments.

The best methods to improve ventilator reliability and accuracy

Image Credit: Superior Sensor Technology

A variety of medical ventilators are available for use in different environments:

  • Transport ventilators: First responders, ambulance services, and helicopter transport use transport ventilators. In emergencies, these electronic ventilators supply breathing assistance until a patient is transferred to a hospital. They are more compact and robust than their hospital counterparts and offer diverse power source options. 
  • Intensive care (ICU) ventilators: Large ventilators are located in hospitals and powered by AC electricity. They are used in the surgical and ICU areas and offer comprehensive features and capabilities. 
  • Critical care ventilators: Although lacking some of the features of ICU ventilators, critical care ventilators are equipped with enough functionality to manage emergencies and long-term critical ventilation situations. These ventilators tend to be found in hospitals’ emergency and specialized care units.
  • Home ventilators: These smaller devices assist patients who cannot breathe independently after discharge. A home ventilator continues to support a patient’s breathing until they can do so without assistance.

Neonatal ventilators are medical ventilators designed explicitly for neonatal and infant patients. The key difference is that they are intended to provide lower and more precise rates of ventilation.

Modern medical ventilation systems are controlled electronically, with embedded processing that precisely regulates air pressure and flow according to each patient's specific requirements. These systems are considered to be life-critical because a system failure could cause severe patient harm.

Before the COVID-19 pandemic, medical ventilators were fundamental to hospital care. However, the demand for ventilators has risen substantially over the last few years.

Hospitals routinely use high-pressure ventilators, which are tank-based and built into the infrastructure. However, the current trend in medical ventilation is towards portable solutions, specifically low-pressure units. These mobile units are equipped with a miniaturized O2 tank or can function without one.

Ease of transport is a major advantage of these devices. They can provide increased mobility for the patient and be easily relocated when required.

These modern systems have a blower mechanism that produces the required air on demand instead of full-sized tanks. The blower operates like a standard fan, using blades to create airflow. The blades' noise is a challenge, and it must be addressed to guarantee accurate and efficient operation.

Superior Sensor VN Series improves ventilator performance

A number of medical studies have suggested that approximately one-third of patients experience dyssynchrony during mechanical ventilation. This is when the ventilator does not match the patient’s breathing requirements.

This can result in increased respiratory work, lung damage, discomfort, extended ventilator reliance, and weaning difficulties. To improve synchrony, ventilators must respond faster to patient breathing demands and eliminate the impact of system noise.

Pressure sensors in ventilators, crucial for monitoring and controlling airflow, can be affected by system noise from internal blowers and external vibrations. Traditional systems often slow down response time by oversampling sensor data, further complicating the issue.

Designed specifically for medical ventilators, the VN Series by Superior Sensor uses an innovative oversampling technique that effectively eradicates all noise beyond the relevant band. This proprietary technology allows mechanical ventilators to use sensor outputs at their maximum speed, eliminating the requirement for oversampling sensor outputs and decreasing the system response time by as much as tenfold.

The series is made up of seven devices, each of which caters to a broad spectrum of system applications, ranging from flow measurement to inlet, inspiratory, expiratory, and barometric pressures. 

Advanced digital processing significantly reduces system-level noise interference. Additionally, the sensors boast 24-bit output resolution, improved filtering, remarkable zero stability, and are capable of supporting an update rate surpassing 1 kHz.

They have been meticulously designed to enhance system accuracy and reduce error rates. This proves especially advantageous for patients facing life-threatening respiratory conditions.

The table below highlights the uses of different sensors within the VN Series.

VN Series Product Family

The VN026CM and VN131CM offer extreme bandwidth resolution, enhancing the sensor’s effective resolution, amplifying the dynamic range, and reducing the noise floor by an additional 20 dB.

The VN026CM and VN131CM have the lowest noise floor and, for the first time, can offer manufacturers single-sensor solutions catering to numerous respiratory requirements for neonates and adults.

Comparing Extreme Resolution to Standard Resolution and Competitive Offerings

The VN Series sensors have integrated additional features like advanced digital filtering and a three-mode pressure switch. These transform pressure sensors into sensing subsystems, increasing manufacturing efficiency and reliability.

Every VN Series sensor uses the same footprint and is pin-compatible with each other. The simplified PCB layouts allow manufacturers to easily interchange VN Series sensors for a variety of applications.

Conclusion

The VN Series employs cutting-edge digital signal processing and noise filtering methods to enhance medical ventilator performance. By facilitating rapid sensor data retrieval and eliminating interference, the sensors enable ventilators to adapt promptly and precisely to patient breathing patterns.

This heightened speed and accuracy, coupled with advanced functionalities such as three-mode pressure switching, can notably enhance patient-ventilator synchronization and minimize discomfort.

Offering industry-leading resolution and noise reduction within a standard footprint, the VN Series provides ventilator manufacturers with a flexible pressure-sensing solution to enhance system dependability and more effectively cater to the needs of critical care patients.

Major global ventilator manufacturers, like Vyaire, trust Superior Sensor Technology to supply their differential pressure sensors.

People with post-COVID syndrome (PCS) following the COVID-19 infection often suffer from intense fatigue and dyspnea. This is what emerges from a new Nordic study led by Umeå University and recently published in the BMJ Public Health journal. High blood pressure also appears to be a risk factor for PCS diagnosis, according to the study’s findings.

"These scientific results are an important step in better understanding PCS. By identifying key factors, we can improve diagnosis, adapt care and pave the way for research into more effective treatments," says Anne-Marie Fors Connolly, MD PhD, Assoc Prof, clinical researcher at Umeå University and the study's senior author.

The study analyzed data from over one million people in Sweden who tested positive for COVID-19 during the period from February 2020 to May 2021. Of these, 1.5 percent, just over 16,000 people, were diagnosed with PCS after the main COVID-19 infection. They were diagnosed in both outpatient and inpatient care, which provided large datasets for the researchers to examine the clinical footprint of PCS. The researchers conducted an in-depth study of PCS symptoms in individuals who required ongoing healthcare three months after the COVID-19 infection.

The researchers found that the most common symptoms associated with PCS were dyspnoea (difficulty breathing), malaise, and fatigue, as well as abnormal lung examination findings. People with PCS were more likely to have hypertension and high blood pressure compared to both people who had undergone COVID-19 infection without later being diagnosed with PCS and compared to people who had not contracted COVID-19 at all. This indicates a vulnerability in people with high blood pressure. Notably, dyspnoea emerged as a new symptom for the majority of those diagnosed with PCS, underscoring its significance in PCS symptomatology and how clinicians diagnose PCS.

In determining which COVID-19 patients were diagnosed with post-COVID syndrome, a strong correlation was observed with the severity of illness during the early stages of infection. In particular, individuals who required mechanical ventilation for breathing assistance were at high risk of being diagnosed with PCS after recovering from the COVID-19 infection.

The study's comprehensive approach, leveraging data from multiple nationwide registries, provides a unique overview of PCS and valuable insights for healthcare providers. The results underline the importance of future studies on the underlying causes and potential treatments of PCS.

"Our study elucidates symptomatology and how clinicians diagnose PCS. Understanding the clinical and demographic characteristics of PCS is crucial to develop targeted care strategies for those suffering from long-term effects of COVID-19," says Dr. Hanna Ollila, FIMM-EMBL Group Leader at the University of Helsinki.

The study is developed within the EU-funded research project NeuroCOV and is additionally funded by the Swedish Research Council and Academy of Finland. Led by Umeå University, it involves institutions in four Nordic countries, including the Swedish and Finnish nodes of the Nordic EMBL Partnership for Molecular Medicine, the Laboratory for Molecular Infection Medicine Sweden (MIMS) and the Institute for Molecular Medicine Finland (FIMM) at University of Helsinki.

A protein in the lungs could be activated to treat those who suffer from allergic asthma, according to a new study.

American researchers found a protein called Piezo1 prevents a type of immune cell in the lung from becoming hyperactivated by allergens.

Activating this protein using a drug called Yoda1 could be used to treat those with allergic asthma and reduce the debilitating symptoms of the condition.

Initial experiments with mice found the drug alleviated symptoms in allergen-exposed mice, suggesting it may be useful as a therapeutic tool for humans.

Type 2 innate lymphoid cells - also known as ILC2s - are a type of immune cell located in the lungs, skin, and other tissues of the body.

ILC2s in the lungs become activated in the presence of allergens and produce proinflammatory signals that drive the recruitment of other immune cells into the lungs.

Unchecked, this can result in excessive inflammation and a tightening of the airways - making it difficult for asthma patients to breathe properly.

The study, published in the Journal of Experimental Medicine by researchers from the University of Southern California (USC), discovered that when activated by an allergen, ILC2s produce a protein called Piezo1 that can limit their activity.







Activating protein in lungs ‘could be used to treat allergic asthma’

Activation of ILC2s causes inflammation in mouse lungs (L), but this is reduced by treatment with Yoda1 to stimulate Piezo1 channels (R). (Hurrell et al. via SWNS)




Professor Omid Akbari, of USC’s Keck School of Medicine, said: "Given the importance of ILC2s in allergic asthma, there is an urgent need to develop novel mechanism-based approaches to target these critical drivers of inflammation in the lungs."

Piezo1 forms channels in the outer membranes of cells that open in response to mechanical changes in the cell’s environment, allowing calcium to enter the cell and change its activity.

Dr. Akbari’s team found that, in the absence of Piezo1, mouse ILC2s became more active than normal in response to allergenic signals, with the animals developing increased airway inflammation.

However, when treated with a drug called Yoda1 that switches on Piezo1 channels, the activity of ILC2s was reduced, airway inflammation decreased and the symptoms of allergen-exposed mice were alleviated.

The researchers' observations suggest a significant role for Piezo1 channels in ILC2 metabolism, as treatment with Yoda1 reduced ILC2 mitochondrial function and rewired the cells’ energy source.

Dr. Akbari's team determined that human ILC2s also produce Piezo1 and tested the effects of Yoda1 on mice whose ILC2s had been replaced with human immune cells.

“Remarkably, treatment of these humanized mice with Yoda1 reduced airway hyperreactivity and lung inflammation, suggesting that Yoda1 may be used as a therapeutic tool to modulate ILC2 function and alleviate the symptoms associated with ILC2-dependent airway inflammation in humans,” Dr. Akbari said.

“Future studies are therefore warranted to delineate the role of Piezo1 channels in human patients with asthma and develop Piezo1-driven therapeutics for the treatment of allergic asthma pathogenesis.”

Our Borderplex community has a new pulmonary and critical care medicine specialist who plans to enhance lung disease screening protocols and programs to benefit patients and the future physicians who will care for them.

Sheldon Rao, M.D., is seeing patients at the Texas Tech Physicians of El Paso at Alberta clinic and has also joined the Texas Tech Health El Paso Department of Internal Medicine as an assistant professor.

Only a couple of centers and hospitals in El Paso County focus on critical respiratory care, the life-saving care for patients experiencing respiratory issues that cause trouble breathing. With over 800,000 living in El Paso County, Dr. Rao’s pulmonary and critical care skills will help underserved communities in need of his expertise.

“Pulmonary rehabilitation, when done appropriately, has an immense effect on survival, as well as the quality of life in people with end-stage lung disease,” Dr. Rao said. “I aim to introduce new technology and devices which can help those patients with lung disease.”

Before arriving at Texas Tech Health El Paso, Dr. Rao completed a pulmonary and critical care medicine fellowship at the Allegheny Health Network Medical Education Consortium in Pittsburgh, Pennsylvania, where he also completed his internal medicine residency. He received his bachelor’s degree in medicine from St. John’s Medical College in Bangalore, India.

Most of Dr. Rao’s research interests revolve around improving patients’ quality of life, and determining if the care they’re receiving improves the overall health of the community without being wasteful. He has published or co-published numerous journal articles and papers on timely pulmonary and critical care issues, including the challenges health care workers face when caring for COVID-19 patients, hematologic and oncologic emergencies in an intensive care setting, and asthma in pregnant women.

My wife, Susan, and I have traveled around the world by trains, planes, ships, and automobiles finding new adventures. We are now in Amsterdam — our first international trip since 2019.

When I was diagnosed with idiopathic pulmonary fibrosis (IPF) in January 2017, my care team encouraged me to live my best life. I did, including by traveling to places Susan and I wanted to ensure we could visit together.

When COVID-19 hit, my care team advised against unnecessary travel. Plus, my IPF had begun to progress more quickly. I was approved for a lung transplant in March 2020 but deferred, due to the pandemic. It was a year later, almost to the day, when I was listed. I received my bilateral lung transplant in July 2021, which restricted my travel for another year.

Preparation

We have traveled to all seven continents, taken an untold number of cruises, and consider ourselves to be seasoned travelers. I typically get excited before a new adventure, especially when it involves international travel. Yet preparing for this trip as a post-transplant patient was a completely different experience.

I arranged to see my kidney care team, my cardiac surgeon, and my transplant care team during the first half of March. All of them gave me guidance on things to be aware of while traveling abroad.

Because I am immunosuppressed to reduce the risk of my body rejecting my transplanted lungs, I am more susceptible to illness. Even though I’m vaccinated against the flu, COVID-19, and respiratory syncytial virus, I will be masked during our flight and when we are among crowds.

Due to swelling in my lower legs, I will not spend the seven-hour flight sitting. I will walk up and down the aisle and otherwise keep my legs elevated for as much time as possible. Anticipating the need for elevation, we opted to splurge on business class seats, which will allow us to lie flat during the flight.

Packing for vacation post-transplant requires some level of concentration. (Photo by Sam Kirton)

The most challenging aspect of packing for this trip was not deciding what to wear, but thinking through all of my medication requirements.

My care team’s guidance was clear: Prepare for the unexpected. Pack twice the amount of medication you think you’ll need.

I did just that, preparing a 20-day supply of my medications for our seven-night cruise.

Additionally, I asked my care team to prepare a letter listing all of my medications. During a cruise around Australia and New Zealand, local authorities met with all passengers carrying prescription medication during the ship’s immigration processing. The trip documentation suggested that some countries require prescriptions to be carried in their original containers.

When we left our home in Virginia to embark on the trip to Amsterdam, we double-checked that we had all the necessary medications. I also had a plan to adjust my medication schedule to accommodate the time zone change.

Why Amsterdam?

My IPF journey has affected our ability to travel, especially internationally, which we both love to do. Susan sacrificed so much when she assumed the role of caregiver. Some years ago, she talked about wanting to see the tulips bloom in Amsterdam. This trip will allow her to realize that dream.

We are aboard the AmaLucia, sailing out of Amsterdam for a seven-night “Tulip Time” river cruise. The ship carries 156 passengers, so it’s not like the larger ones we’re accustomed to. Two days before we flew to Amsterdam, we received photos of the tulip fields we will be visiting in full bloom.

Next week, I will share more with you about navigating a river cruise as a post-transplant IPF patient. I started taking notes on the day we left so I can report back to you about this vacation. I want you to ask questions; feel free to post them in the comments. Sharing my experience is how I can continue to make every breath count.

Introduction

The high-flow nasal cannula (HFNC) has become an essential non-invasive oxygen therapy device. Recently, it has been used widely in clinical settings as a non-invasive respiratory support method to improve oxygenation in adult patients.1 HFNC has several advantages over conventional low-flow devices (eg, nasal cannula or simple face masks): enhanced patient comfort, increased humidification, improved secretion clearance and reduced effort in breathing.2,3 The HFNC system is a unique device that is simple and easy to use, needing only an active heated humidifier, flow generator, single circuit, and soft nasal cannula.4 This device was developed to maintain high oxygen flow and improve the efficiency of ventilation by delivering warmed and humidified oxygen with a flow rate as high as 60 L/minute and a fraction of inspired oxygen (FiO2) of 0.21 to 1.0. An increased flow rate can help reduce inspiratory effort and improve dynamic lung compliance, which can lead to improving oxygenation and ventilation.1,5,6 During the COVID-19 pandemic, several studies showed that the use of HFNC as an alternative oxygen device for respiratory failure patients can provide higher oxygen concentrations than can be achieved with conventional devices, reduce the need for endotracheal intubation, and decrease the length of stay in intensive care units (ICUs).7–9 In addition, HFNC has a valuable effect in reducing anatomical dead space, which provides low positive end-expiratory pressure (PEEP) and can be more tolerable for patients with chronic obstructive pulmonary disease (COPD).10 Moreover, the immediate use of HFNC for postoperative respiratory failure patients was associated with lower risks of reintubation and respiratory failure.11

Even though the use of HFNC is prevalent in clinical settings, RTs still lack evidence-based guidelines for implementing HFNC.12 Moreover, HFNC is frequently utilized by RTs but controversy remains on the initiation, management and weaning of HFNC due to scant evidence.12–14 A cross-sectional study of French ICU physicians found that there was a great deal of variability in the current use of HFNC, including the criteria for initiation and weaning.15 Furthermore, a global survey of intensive care unit (ICU) healthcare providers reported that there was considerable variation in the daily application of HFNC with regard to initial settings and management criteria for HFNC parameters.16 HFNC failure may result from these notable differences in clinical practice, which is probably due to lack of educational training and standardized protocols.17

Despite the wide use of HFNC and the studies exploring the benefits of using HFNC with ARDS patients, research into assessing the knowledge, practice, and barriers to using HFNC among respiratory therapists in Saudi Arabia is lacking. Therefore, this study aimed to assess the current practice of HFNC in multiple centers in Saudi Arabia and identify the barriers to using HFNC among respiratory therapists.

Methods

Study Design

In this cross-sectional study, a survey was distributed through an electronic platform SurveyMonkey between December 19, 2022, and July 15, 2023.

Instrument

Experts in the use of HFNC (namely ICU physicians, respiratory therapists, and ICU nurses) formulated this questionnaire, which was adapted and modified from previous studies.8,15,16,18 Next, face and content validity were assessed by an expert panel and the survey was then pilot-tested. After receiving feedback from the experts, adjustments were made, and the survey was distributed. The survey consisted of six main parts:

  • The first part asked the participants about their demographic information (eg, gender, number of years working in critical care areas, and geographical location).
  • The second part focused on assessing the study participants’ knowledge of indications for the use of HFNC. This part consists of 13 statements with a five-point Likert scale ranging from 1 to 5 (1 = strongly agree; 5 = strongly disagree).
  • The third part consisted of four statements with a five-point Likert scale ranging from 1 to 5 (1 = strongly agree; 5 = strongly disagree). This section assessed whether respiratory therapists agree that 1) the HFNC device is tolerable for patients, 2) HFNC is used to help patients eat and speak, 3) HFNC improves dyspnea, and 4) HFNC is used to avoid the need for intubation and invasive mechanical ventilation.
  • The fourth part assessed the study participants’ ability to determine the timing for switching to HFNC, the most appropriate initial settings for HFNC, the management of patients on HFNC, and the criteria required for weaning.
  • The fifth part consisted of four statements to evaluate whether the study participants were aware of the criteria for HFNC failure and the time to intubate and use invasive mechanical ventilation.
  • The last part consisted of one question about barriers to HFNC use.

Data Collection and Sampling

A convenience sampling strategy was used to recruit the study participants, and the main target population for this study were respiratory therapists who work in Saudi Arabian hospitals and hold a bachelor degree. To reach a larger population of respiratory therapists, we distributed the survey through Saudi scientific non-profit organizations (eg, the Saudi Society for Respiratory Care) along with social media platforms (X and WhatsApp). In addition, each data collector visited and circulated the survey to respiratory therapists working at their nearby tertiary hospitals.

Data Analysis

The collected data were managed and analyzed using the Statistical Package for the Social Sciences (SPSS) version 27. Data were presented as means and standard deviation or frequency and percentages, as appropriate. A Chi-square test was used to compare RT staff who have existing HFNC protocols and those who do not. A p-value of <0.05 was considered statistically significant.

Ethical Approval

Before the commencement of the study, ethical approval was obtained from the Bioethical Committee at Batterjee Medical College (Reference Number RES-2022-0077).

Results

Participant Characteristics

In this study, 1001 RT practitioners completed the online survey. Over half of the participants were female (573, or 57.2%). The majority of our sample was staff specialists (824, or 82.3%), while directors of RT departments accounted for 29 (2.9%). High numbers of representatives were from the country’s Western and Central Regions (52.8% and 26.4%, respectively). More than half (56.1%) of the participants had one to five years of clinical experience. In addition, we documented the areas where the respiratory therapists were assigned, such as critical care (78.6%), non-critical care (65.5%), and ER (57.9%). Two-thirds of the respiratory therapists (659, or 65.8%) had received training on HFNC and 785 (78.4%) had used HFNC in clinical settings. (See Table 1).

Table 1 Demographic Data and Characteristics of Study Respondents (n = 1001)

Indications of Using High-Flow Nasal Cannula from the Perspective of RT Staff

We asked the participants if they agreed about the relevant indications or conditions that require HFNC. The top responses were COVID-19 (78%), post-extubation (65%), and do-not-intubate patients (64%). The lowest responses were pre-oxygenated patients before intubation (38%), obesity-induced hypoventilation syndrome (34%), and sleep apnea syndrome (33%). (See Table 1 and Figure 1).

Figure 1 Indications for using HFNC from the perspective of RT staff (n=1001).

Advantages of Using High-Flow Nasal Cannula

Four advantages of HFNC (ie, has high tolerability, helps maintain conversation and eating abilities, improves shortness of breath (SOB), and avoids intubation) were reported from the perspective of respiratory therapists. Participants strongly agreed that the advantages of HFNC were helping to maintain conversation and eating abilities (32.95%) and improving SBO (34.1%) (See Table 2 and Figure 2).

Table 2 Advantages of Using HFNC from the Perspective of RT Staff

Figure 2 Advantages of using HFNC from the prospective of RT staff (n=1001).

Initial Settings, Weaning and Disconnect of High-Flow Nasal Cannula

Surprisingly, 568 (57%) of RT staff do not follow a protocol for initiation, weaning and disconnection of HFNC with ARDS patients.

When starting HFNC, 40.2% of the participants started with FiO2 of 61% to 80%. Additionally, a high percentage of RT staff (40.6%) started with a flow rate between 30 L/minute and 40 L/minute and a temperature of 37°C (57.7%). When weaning ARDS patients from HFNC, 482 (48.1%) recommended first reducing gas flow by 5–10 L/minute every two to four hours, followed by 362 (36.2%) who recommended first reducing FiO2 by 5–10% every two to four hours. Moreover, 549 (54.8%) believed that ARDS patients could be disconnected from HFNC if they achieved a flow rate < 20 L/minute and FiO2 <35%. (See Table 3).

Table 3 Clinical Practice of HFNC

In addition, we compared the responses between participants who followed a standardized protocol versus those who did not follow a protocol to initiate, wean and disconnect HFNC. (See Table 3).

Of the 402 RT staff who would start with FiO2 between 61% and 80%, 289 (28.87%) reported not following a standardized protocol. Additionally, half of the RT staff (214, or 21.42%) who would start with a flow rate between 30 and 40 L/minute do not have a standardized protocol to follow. Among all participants, we observed a statistically significant difference between respiratory therapists who follow a protocol versus those who do not (p-value <0.001). For those who recommended first reducing gas flow by 5–10 L/minute every two to four hours when weaning ARDS patients, 356 (35.51%) did not follow a standardized protocol. Among all participants, we observed statistically significant differences between respiratory therapists who follow a protocol and those who do not follow a protocol (p-value <0.001). (See Table 3).

Criteria to Stop High-Flow Nasal Cannula and Intubate Acute Respiratory Distress Syndrome Patients

Regarding the criteria to stop providing HFNC and initiate intubation, 39.5% of the participants would stop providing HFNC if the patient paused or stopped breathing. Indeed, 34.7% of the participants would stop providing HFNC in cases of refractory hypoxemia (SpO2 < 90% with FiO2 100% and flow rate of 60 L/minute), 35% in cases of severe respiratory acidosis (pH is unacceptably low (<7.25) and the PaCO2 is elevated), and 39.3% in cases of reduced level of consciousness (GCS score ≤8). (See Table 4).

Table 4 Criteria to Stop HFNC and Intubate ARDS Patients

Challenges in Using High-Flow Nasal Cannula

Regarding the challenges that impede the use of HFNC, participants ranked lack of knowledge, lack of devices, and the absence of protocol as the highest challenges (57.3%, 49.6, and 49%, respectively) while lack of evidence and diversity of HFNC devices were the lowest challenges 34.5% and 17.2%, respectively. (See Figure 3).

Figure 3 Challenges toward using HFNC from the perspective of RT staff (n=1001).

Discussion

To the best of our knowledge, this is the first national study to shed light on the knowledge, attitudes, and current practice of HFNC in ARDS patients among respiratory therapists in Saudi Arabia and the barriers to its use in clinical settings. The study findings revealed nuanced applications marked by significant endorsement in certain clinical scenarios and a lack of protocol adherence, underscoring the need for uniform, evidence-based guidelines and enhanced training for respiratory therapists.

A significant finding in our study is the prominent endorsement of HFNC use in COVID-19 patients, post-extubation cases, and do-not-intubate patients. These results corroborate existing literature that underscores HFNC’s role in enhancing oxygenation and reducing the effort of breathing in acute hypoxemic respiratory failure.2,3 Similarly, a cross-sectional study disclosed that respiratory physicians in Japan regarded COVID-19 as a primary indicator for HFNC application given its propensity to reduce the frequency of sustained sedation, physical restraint, and length of stay in the ICU compared to patients undergoing non-invasive ventilation (NIV).8 Nevertheless, the lower agreement on HFNC’s application in pre-oxygenation, obesity-induced hypoventilation, and sleep apnea conditions indicates potential knowledge gaps or diverse clinical experiences that warrant further investigation.

HFNC therapy has garnered widespread clinical validation for its efficacy in the management of patients with ARDS. Its capacity to deliver a precise and adjustable flow of warmed, humidified oxygen optimizes patient comfort and oxygenation status and decreases respiratory distress symptoms and the risk of endotracheal intubation.19,20 Within the scope of the present study, a substantial level of consensus was observed among participants, indicating that HFNC application is associated with a notable amelioration of SOB while concurrently preserving speech and eating capabilities. In line with these findings, previous literature has demonstrated the superiority of HFNC over alternative non-invasive respiratory modalities, underscored by its high patient tolerance and preservation of patients’ daily activities, emphasizing HFNC’s pivotal role in enhancing patient-centered outcomes.8

In the current study, significant discrepancies were observed in the setting of initial parameters, weaning strategies, and disconnection criteria pertaining to HFNC. Specifically, a majority of respiratory therapists reported an initial application of FiO2 within the range of 60% to 80%, a flow rate of 30–40 L/minute, and a temperature of 37°C. Notably, these findings are inconsistent with established HFNC protocols, which advocate initiating FiO2 at 1.00, a flow rate of 60 L/minute, and a temperature of 37°C.21,22 Furthermore, a substantial proportion of respiratory therapists expressed a preference for initially weaning the flow rate by 5–10 L/minute every two to four hours, deviating from the guidelines stipulated by the Canadian Society of Respiratory Therapists, which prioritize reducing FiO2 to less than 40% before commencing a gradual decrement in flow rate by increments of five.21 Analogously, heterogeneous practices were observed among French ICU physicians during the weaning process of HFNC settings.15 Despite these variations, a significant consensus emerged among over half of the respiratory therapists regarding the disconnection of HFNC, advocating for disconnection when the FiO2 is below 35% and the flow rate falls below 20 L/minute, aligning with published guidelines.1,21 A noteworthy revelation is the lack of adherence to standardized protocols for initiating, weaning, and disconnecting HFNC for ARDS patients. This inconsistency in clinical practices underscores the urgent need for the development and dissemination of evidence-based guidelines to enhance the quality and consistency of patient care.

Regarding the criteria dictating the transition from HFNC therapy to invasive mechanical ventilation in patients with ARDS, our study revealed a moderate consensus. This alignment was substantiated through the initiation of endotracheal intubation in cases of spontaneous breathing cessation, refractory hypoxemia, severe respiratory acidosis, or diminished consciousness. Concomitantly, a subsequent study yielded analogous outcomes, thereby affirming our findings. Notably, it illuminated the exacerbation of respiratory distress and the presence of bronchial congestion as substantive contributors to the ineffectiveness of HFNC therapy, consequently augmenting the imperative for invasive ventilation.15 Additionally, a retrospective analysis furnished empirical evidence identifying hypoxemic and hypercapnic respiratory failure as crucial indicators denoting the failure of HFNC therapy, particularly in scenarios wherein patients cannot sustain SpO2 above 90% despite receiving maximal FiO2. This insufficiency is accentuated by concomitant findings of arterial pH below 7.3 and respiratory rates exceeding 35 breaths per minute.23 The diverse criteria employed by respiratory therapists to discontinue HFNC and commence intubation emphasize the need for standardization in this aspect. Precisely articulated and evidence-based criteria are instrumental in optimizing patient outcomes and mitigating the potential risks associated with delayed intubation.

Several barriers impede the widespread adoption of HFNC therapy in clinical settings. In the present study, RT staff identified a lack of knowledge, the unavailability of devices, and the absence of protocols as the foremost challenges hindering the optimal use of HFNC. In accordance with these results, existing literature has shown that a lack of skill and familiarity hampers the implementation of HFNC in the ICU.24,25 Likewise, a pertinent study revealed that the absence of established objective criteria for initiating and managing HFNC settings significantly restricts its application, potentially leading to ineffective healthcare practices.26 These findings underscore the necessity for targeted interventions to enhance the capabilities of respiratory therapists, ensure the availability of essential equipment, and establish evidence-based protocols and the importance of concerted efforts to fortify strengths and mitigate the challenges associated with HFNC application in clinical settings.

Strengths and Limitations

One of the notable strengths of this study is the breadth of the participant sample, offering a robust spectrum of insights and experiences from a diverse group of respiratory therapists. The comprehensive survey methodology enabled the capture of nuanced, multifaceted data, allowing for a granular analysis of HFNC practices and challenges. Additionally, the alignment of the study’s findings with existing literature accentuates its validity and contribution to the ongoing discourse on the clinical applications of HFNC. Nevertheless, the study has limitations. We did not assess the current practice and barriers of using HFNC from the prospective of physicians whose practices maybe different from RTs. The reliance on self-reported data introduces the potential for response biases, wherein participants might either consciously or unconsciously misreport their practices. The cross-sectional nature of the study design precludes causal inferences and the assessment of HFNC practice evolution over time. Moreover, the geographical and institutional diversity of participants, while a strength, also raises questions about the generalizability of the findings across different contexts and healthcare systems.

Conclusion

Respiratory therapists in Saudi Arabia demonstrated a profound understanding of the clinical advantages associated with the utilization of HFNC for adult patients with ARDS. However, significant discrepancies were observed concerning the setting of initial parameters, the formulation of weaning strategies, and the determination of disconnection criteria related to HFNC. These variations primarily stemmed from inadequate adherence to established protocols and limitations in available resources. Such observations underscore the imperative for the development and implementation of standardized, evidence-based guidelines, alongside comprehensive training initiatives aimed at enhancing respiratory therapists’ compliance with HFNC protocols.

People with post-COVID syndrome (PCS) following the COVID-19 infection often suffer from intense fatigue and dyspnea. This is what emerges from a new Nordic study led by Umeå University and recently published in the BMJ Public Health journal. High blood pressure also appears to be a risk factor for PCS diagnosis, according to the study’s findings.

"These scientific results are an important step in better understanding PCS. By identifying key factors, we can improve diagnosis, adapt care and pave the way for research into more effective treatments," says Anne-Marie Fors Connolly, MD PhD, Assoc Prof, clinical researcher at Umeå University and the study's senior author.

The study analyzed data from over one million people in Sweden who tested positive for COVID-19 during the period from February 2020 to May 2021. Of these, 1.5 percent, just over 16,000 people, were diagnosed with PCS after the main COVID-19 infection. They were diagnosed in both outpatient and inpatient care, which provided large datasets for the researchers to examine the clinical footprint of PCS. The researchers conducted an in-depth study of PCS symptoms in individuals who required ongoing healthcare three months after the COVID-19 infection.

The researchers found that the most common symptoms associated with PCS were dyspnoea (difficulty breathing), malaise, and fatigue, as well as abnormal lung examination findings. People with PCS were more likely to have hypertension and high blood pressure compared to both people who had undergone COVID-19 infection without later being diagnosed with PCS and compared to people who had not contracted COVID-19 at all. This indicates a vulnerability in people with high blood pressure. Notably, dyspnoea emerged as a new symptom for the majority of those diagnosed with PCS, underscoring its significance in PCS symptomatology and how clinicians diagnose PCS.

In determining which COVID-19 patients were diagnosed with post-COVID syndrome, a strong correlation was observed with the severity of illness during the early stages of infection. In particular, individuals who required mechanical ventilation for breathing assistance were at high risk of being diagnosed with PCS after recovering from the COVID-19 infection.

The study's comprehensive approach, leveraging data from multiple nationwide registries, provides a unique overview of PCS and valuable insights for healthcare providers. The results underline the importance of future studies on the underlying causes and potential treatments of PCS.

"Our study elucidates symptomatology and how clinicians diagnose PCS. Understanding the clinical and demographic characteristics of PCS is crucial to develop targeted care strategies for those suffering from long-term effects of COVID-19," says Dr. Hanna Ollila, FIMM-EMBL Group Leader at the University of Helsinki.

The study is developed within the EU-funded research project NeuroCOV and is additionally funded by the Swedish Research Council and Academy of Finland. Led by Umeå University, it involves institutions in four Nordic countries, including the Swedish and Finnish nodes of the Nordic EMBL Partnership for Molecular Medicine, the Laboratory for Molecular Infection Medicine Sweden (MIMS) and the Institute for Molecular Medicine Finland (FIMM) at University of Helsinki.

Leah J. Witt, MD: Hello. I'm Dr Leah Witt. Welcome to season one of Medscape InDiscussion, chronic obstructive pulmonary disease (COPD) podcast series. Today we're talking medications, especially inhalers and COPD; everything from correct use, cost, and tips for prescribing. I am beyond excited to welcome my friend and today's expert guest, Dr Amber Lenae Martirosov. Dr Martirosov is an ambulatory care clinical pharmacist at Henry Ford Health and an associate clinical professor at Wayne State University. She describes herself as a huge advocate for patients. She practices in an outpatient clinic, where she improves patient outcomes by focusing on getting patients the right inhaled medication at the right price. Welcome to the Medscape InDiscussion podcast, Amber.

Amber Lenae Martirosov, PharmD: Thanks for having me, Leah. It's great to be here.

Witt: We've talked a lot about this topic, and we're going to get into it. Before we do, I want to kick off the episode by getting to know you. What is on your mind outside of medicine?

Martirosov: I've been doing this new thing that I call revenge reading, where I stay up too late reading books because I want to be able to read books. I'm currently reading The Wager, which is a really fascinating book about potential mutiny aboard a ship. It's a really good book. I would recommend reading it.

Witt: I'm revenge listening. I haven't gotten to reading because I fall asleep too fast, but I love podcasts. I started listening to Emily Oster's ParentData podcast. She's an economist who dives into the data about pregnancy and parenting. She has a podcast, and I was just listening to the episode where she interviewed Eve Rodsky, who wrote Fair Play. I highly, highly recommend. She takes such a scientific approach that I think anybody who's in medicine could really appreciate that approach.

Let's get into our case. I'm going to keep our patient the same as in the last episode, and we're going to talk about Mr Rivera. Today, we're talking about medications, especially inhalers. He's a 78-year-old man. We diagnosed him with COPD last episode. He was hospitalized with a COPD exacerbation.

You're seeing him for the first time in your pulmonary clinic to talk about medications. He was discharged from the hospital with a tiotropium soft-mist inhaler (SMI) and albuterol. There was a meds-to-bed initiative. He got the medications, but he doesn't know how to use them. I want to start by asking you, how do you approach that first post hospital follow-up visit?

Martirosov: This is an important question to consider, especially from a provider perspective. One of the things that we see commonly with inhalers is that patients will get inhalers, and either the provider doesn't educate the patient or believes that the patient will be educated when they get to the pharmacy.

This is a missed opportunity for education. We're often seeing these patients say, "I don't know how to use these devices." It's important to understand with this patient specifically that tiotropium SMIs requires the patient to put it together.

It's not packaged in a box that's ready to go. The patient must do some work to assemble it. When I first see these patients, the first question that's always important to ask is, "What inhalers have you used in the past? Can you tell me about how you use them?" If they have not used inhalers, then the next question I ask is, "What do you think you should be doing with this inhaler?" We can start with the knowledge they have and build on that. We then systematically go through the different steps of appropriate use of the different types of inhalers. We go into those nuanced details. When should they be holding their breath? When should they be blowing out their nose? We talk about things like that.

Witt: We have a secret love of both inhaler technique and Medicare Part D. We'll get into that in a second. I want to talk about the new Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines, the holy grail of COPD management, which now recommends for group E, that's the high exacerbation group that he's in because he was hospitalized for an exacerbation, to start a long-acting beta-agonist (LABA)–long-acting muscarinic antagonist (LAMA). This is the same as group B, which is defined as high symptoms and a moderate number of exacerbations. Why do you think that is? Why do the GOLD guidelines suggest going right for the LABA-LAMA initially?

Martirosov: This taps into the pharmacist brain because we're going to talk about pharmacology. When you think about the way that LABAs work and the way that LAMAs work. They are both bronchodilators by nature, but they are targeting different receptors. The LAMA has an added benefit of targeting muscarinic receptors, which then would cause a little bit of anticholinergic effects.

When we combine a LABA with a LAMA, we get this phenomenon known as dual bronchodilation with the added bonus of a little bit of that antimuscarinic effect. This is fantastic for your patients with COPD who we know are going to have some limitations in their breathing and need that bronchodilator to open those airways.

We know that in COPD, these patients are oftentimes going to have a lot of mucus. Now, not only are we opening up those airways, but we are getting an antimuscarinic in there that's going to help to dry up some of that mucus so that the patient either is able to clear it themselves, or the body will naturally take care of the rest.

Witt: Our patient left the hospital with just a LAMA. Would you switch him right away or would you wait and see how he does?

Martirosov: I would ask a couple of questions, but my short answer is yes. We need to switch him because that's what's actually going to benefit this patient. Given the fact that he's already had an exacerbation that led to a hospitalization, we are trying to do everything we can to prevent future exacerbations because that means future worsening of overall lung function.

The short answer is that we want to switch him. But before we do, I want to make sure that he is able to even afford the tiotropium he got on the first round. Then, I would like to assess his ability to use the inhalers before I decide which of the combination therapies I want to switch him to.

That's so important to think about when switching therapies and devices. If your patient couldn't use the first device, you're setting them up for failure because they're not going to be able to use the new device that you give them, even though you're giving them the correct drug therapy.

Witt: What are some of the device delivery options and how would you assess what to give him?

Martirosov: We always have to think about three different types of devices, and then we throw nebulizers in on the back end. Our historic albuterols have always been what we call a metered-dose inhaler (MDI). Then we have dry-powdered inhalers (DPIs). Many people are going to think of the Advair or (the fluticasone propionate–salmeterol Diskus).

Then we have the newer class, which is actually what this patient was prescribed; SMI. Now, I want to make a quick note. I said three, but within the MDI category, the QVAR RediHaler [beclomethasone dipropionate HFA], and it's the only one of its type, is actually what we call a breath-actuated inhaler.

It operates just like a MDI, but instead of the patient having to depress a canister, the canister will naturally depress as the patient inhales. It is a breath-actuating canister depression that it administers it. It is the only device like that. It technically falls under a metered-dose, but just want to make sure our audience is aware of those differences.

One of the things that's really important when we think about these different devices is the breath technique. This morning, I had a conversation with one of our respiratory therapists (RTs), who's been an RT for 40 years. She said, "Wait, we don't use MDIs quick and fast?" And I said, "Actually that's the worst way to use them." If you think about a MDI or a breath-actuated inhaler, there is a forceful spray behind that. If the patient matches that with a forceful and quick inhalation, the only place that medication can go is to the back of the throat. What we want our patients to do is create a very soft breath. When they start to inhale, we don't even want it to be audible. It should be just like a normal respiratory effort, slow and steady. They should press the canister for about 1-2 seconds after they've started to inhale and then continue that inhalation process for as long as possible. That's different from a DPI. With a DPI, we have this powder that we have to aerosolize. With that device, what we actually want our patients to do is take a very deep and steady breath. Their breath should be audible, but it needs to be steady enough that the patient can inhale for about 4-5 seconds to ensure that that medication will deposit within the lungs.

With those SMIs, the technique should be identical to that of what we would use for the MDI. That very slow, steady, not audible breath for as long as possible.

Witt: It's hard for patients to understand all the technique differences. It's not something that I learned in training. Learning yourself and training yourself is really the first step. I know that in pharmacy school, you get a lot more education about that. I'm sure you've had a lot of experience teaching other doctors about how to use inhalers. What have you seen? We're terrible, right?

Martirosov: I work in a pulmonary clinic, and every year, I test our fellows. In 10 years of practice, I can count on one, maybe one and a half, hands how many of our fellows have gotten it correct with their inhaler technique. That's important to talk about because these are pulmonologists, they're trained to be able to educate patients. There are a lot of different devices, and there's a lot of things that physicians have to master. Asking them to then get inhaler technique right and being able to classify these devices the correct way so that they can educate correctly, that's intimidating. It also may not be something physicians want to spend their time on, when they have other diagnostic things to consider to ensure that patients get the best care.

There are some great tools, though, that you could easily use. There are some great apps that you can download on your phone that make it easier for you as a physician to just pull out your phone and say, "Hey, let's look at this together to make sure that we're doing this correctly."

There are also good resources through the Asthma & Allergy Network, which give you a nice picture of all the different device types and explains whether it's a MDI, breath-actuated inhaler, DPI, and things like that. There is also a new one through the American Lung Association.

There are some tools that you can use to assess whether or not your patient can use their inhalers correctly. Currently, there are two that have been studied. The first one I'll talk about is the Vitalograph Aerosol Inhalation Monitor. What's nice about this is you can use it to train your patients on the correct breath technique. You can also use it to assess them.

If they're not able to correct that technique after multiple education attempts, then that tells you that they need to switch to a different device. The second device that we can use is only going to help you assess inspiratory effort, and whether or not your patient is going to be able to generate enough flow to aerosolize the product appropriately. That device is called the In-Check DIAL.

Witt: The app that I love is the COPD Foundation app. They have a list of inhalers that you could choose by category, and then in the app, but also on YouTube, they have videos that you can share. This highlights how important the interprofessional team is because we all educate ourselves as much as we can. For example, we rely on you as a pharmacist in the clinic, or our advanced practice providers who are skilled at teaching patients about device use. It's so important. Do you have any idea of what you would recommend for our patient, Mr. Rivera? In the second part of the case, I chose one. If he had arthritis, for example, or cognitive impairment, how would you think about that?

Martirosov: I'm a big fan of the SMIs because it is such a nice delivery device for patients that might have advanced COPD. They may lack inspiratory effort. That soft mist replicates a nebulizer machine so we can ensure that the patients are getting more deposition into the lungs.

It comes back to whether the patient can put it together. If this patient has arthritic hands and isn't able to open the device to put the actual canister in and then twist it to be able to administer the dose, that's a problem. In that case, we would probably want to switch them to an alternative agent.

I find that some of my big, barreled-chest patients are great at that deep, steady breath. But then, when I ask them to slow it down, they say, "I don't know what you're talking about. I don't know how to do that." In that patient, where I can't get them to do that very slow, not audible, steady breath, I'm probably going to want to switch to a DPI. I know that DPIs, in this patient, is likely going to get better absorption down into the lungs vs the back of the throat. We would get the back of the throat deposition if this patient was using an SMI or that MDI, because they're using that very deep, breathy, inhalation technique.

Witt: Let's continue the case. Perhaps this hospitalization happened at the end of the year. Mr Rivera sends you a MyChart message in January. This is the beginning of the year on his next refill, you switched him to a LABA-LAMA, a low tiotropium-olodaterol SMI. He says his out-of-pocket cost is $450. He chose a Medicare Part D plan during open enrollment years ago before he had any medical problems, and he hasn't changed it since. He chose it based on the lowest monthly premium, but it has a high deductible. He asks whether you have any advice for him. I'm the medical director of our clinic. I see this every January, and I get a lot of questions like I don't understand why are the costs so high? Where are we getting so many medication rejections messages from pharmacists? Can you explain what's happening?

Martirosov: This is Medicare in a nutshell. We have three parts of Medicare that really cause problems for us as providers. The first is January, when the Medicare cycle restarts. If a patient has a deductible, that deductible will be due in January, which means when they go to pick up their high-cost drugs, typically brand-name drugs, they will be responsible for paying that deductible before they are able to get whatever their insurance pricing is.

I would bet money that this patient is in that initial coverage phase. Because of that, he is now responsible for this high deductible before his insurance will cover the cost of that drug for him. Then, he's going to get into a stage where he's going to be great, maybe he'll be able to afford it, maybe he won't.

I suspect that he's probably going to struggle if he picked an insurance plan based on the lowest premium, because oftentimes the lowest premium means the highest out of pocket costs for our patients. He'll be in what we consider like the coverage phase where maybe he only has to pay $45 for that brand name inhaler, or maybe he has what we would call a co-insurance where he's responsible for 20% or 30% of the average wholesale price.

What happens, though, in a lot of these patients, especially patients who pick their insurance plans based on the lowest premium, is that toward the later part of the year, usually August, September, if they are on a lot of high-cost drugs, they're going to enter what we call the coverage gap or that donut hole. That's a term many of you are probably familiar with. Now, the costs go up again, and that's because the patient has reached their maximums that the insurance have set, in terms of drug costs or other costs. The patient is now responsible for a larger share until they can get themselves out of that donut hole and into what we would then call catastrophic coverage. Leah, we have talked about Medicare. You and I are both very passionate about how we all need to understand this better. We need to be able to better educate our patients on this so that they can make better informed decisions, but it's such a hard thing, especially in the pulmonary world, because we have so few generics that we can rely on. More so than a lot of other, disease states and organ systems, we see a lot of issues with the Medicare plan coverages because we don't have generics to fall back on, so that we can provide our patients with different options.

Witt: So much changes year to year. This year, in 2024, there are good changes. The Inflation Reduction Act that was passed in 2022 is starting to lower some costs. It's eliminating the cost sharing for drugs in the catastrophic phase of coverage. Functionally, the cap is going to be around $3300 dollars, and then 2025, the cap will be $2000 dollars. That will help. But just like you said, planning for January is so important. Then, there are formulary changes, where the inhaler that a patient was on the previous year may not be the preferred inhaler. That's so hard and so disruptive.

Martirosov: To add to your point this year, that disruption was even worse. In late December, we found out that Flovent is no longer going to be available, but then all these formularies for January 2024 said that Flovent is their preferred inhaled corticosteroid. But wait, it's not available.

What do we do? At least in my clinic, it required a lot of prior authorizations because we had to figure out what was going to be covered or wait for them to come out with new formularies. I agree, the formularies are difficult. Understanding Medicare Part D as a collective whole is difficult.

Some of the Inflation Reduction Act is going to make a big difference, and overall, when we think about the Affordable Care Act, one of the goals was that it was going to shrink down that donut hole, that coverage gap, and it slowly but surely has. We've seen legislation about insulin and things like that, but we still have a long way to go before we make a difference in our pulmonary patients.

Witt: Do you have tips? This medication could easily be on his formulary, and his out-of-pocket cost is just high because he hasn't reached his deductible yet. Is there any way to know for sure, when you send it to a pharmacy, if it's going to be on the formulary? Are you counseling people in advance that it might be expensive? How do you navigate that?

Martirosov: It's a hard thing to navigate. One of the things you can do is trying to be aware of the resources are available to you. There are a couple of different websites like CoverMyMeds. These prescription websites will give you an idea of what the formularies are. The problem is that they are never 100% accurate because formularies change.

One Blue Cross Blue Shield insurance card, depending on which patient it's going to, may have five different formularies. The first thing is educating your patients. You brought up a good point, talking to the patients and saying, "Hey, these medications can be expensive. Don't hesitate to call me or call the clinic if it is expensive so that we can then intervene on your behalf." That's number one. Number two is being willing to try to see if there are drug assistance programs through the manufacturer. Something like tiotropium-olodaterol is still brand-name only. As such, there is federal legislation that even for your Medicare patients, while they're in the coverage gap for Medicare Part D, you could potentially get that patient free drug from the manufacturer for the rest of the year, which is a big win.

It's something that we have done in my clinic successfully for a very long time. I'm not always the biggest fan of things like GoodRX or shopping around, but if your hands are tied, you have to do the best that you can with potentially using GoodRX or, you know, some equivalent to that website. You might be able to say, Hey, your insurance is going to be, $400.

But if you pay cash price at this store with this coupon, it's only $120. Sometimes that is enough to make a difference. The last thing that I will mention, which I don't blanket say that we should do for our patients, is there's always nebulized solutions.

Here's the tricky thing with nebulized solutions. You have to determine whether or not the patient is covered by Medicare Part D vs Medicare Part B. With Medicare Part B, the patient often has a 20% coinsurance, which is oftentimes much cheaper than that deductible or whatever they're required to pay in the donut hole.

However, that doesn't always apply for our LAMAs or LABAs because they're brand-name only. So sometimes, if there is a patient with Medicare Part B vs D, and at your very worst, you have to get your patient something, there is always the alternative of putting them on short-acting beta-agonist and short-acting antimuscarinic, like ipratropium, but then scheduling it so that it's used around the clock like it's a long-acting agent. It's not perfect, but when you're desperate, you have your work around. It's an option. It's not the best option, and I would reserve it only in your patients where you're desperate to do something,

Witt: Thank you so much for reviewing this. There's always so much to learn. The last thing I always encourage people to do is review their Part D plan every fall during open enrollment. There's a really good website called Medicare Plan Compare. You can put in your medications and see what the best plan is for you. There are programs, in my area, and I think it might be federal, but I'm not 100% sure. There's a health insurance counseling and advocacy program where you can meet with somebody like a counselor to help you pick a good plan. Do you have that in your state?

Martirosov: Yes. I think it's a statewide requirement. They're great resources for patients.

Witt: I could talk to you all day about this, but we have to wrap up. Any key points that you want to leave our listeners with or resources they should check out?

Martirosov: I would just belabor the point that I always belabor, which is if you don't feel comfortable using inhalers, how can you expect your patients to do it? Please educate yourself so that you can then educate your patients and make a world of difference.

Witt: I feel the same way about understanding Medicare. COPD is a mostly a chronic disease in people who are likely on Medicare. There are some exceptions, but I think it's so important to understand the basics of Medicare Part D so you can talk to patients about why their costs are what they are and help brainstorm with them about reducing costs. Thank you so much again, Amber. Today we've talked to Dr Martirosov about inhaler choice and barriers to use, including high cost of care, my secret favorite topic in medicine. There is nothing more I love then nerding-out to Medicare Part D. Thank you so much for joining us. Take a moment to download the Medscape app to listen and subscribe to this podcast series on COPD.

A team of AI researchers at Google Research, working with a pair of colleagues from the Center of Infectious Disease Research in Zambia, has developed a machine learning system aimed at diagnosing lung diseases based on the sounds of coughing. In their study, available as a preprint on the arXiv server, the group used YouTube videos to train the system.

The team at Google named their new system Health Acoustic Representations (HeAR)—they began working on it after health care workers reported that they had learned over time during the pandemic that they could often tell which patients had COVID-19 by the sound of their cough. Other researchers have been working on similar efforts, hoping to develop systems that could detect a wide variety of diseases based on the sound of a cough.

Google took a different approach to disease detection than the other teams. Instead of training an AI system using recordings with labels that identify a given disease, they used an approach much like that used to create LLMs such as ChatGPT.

In their system, a large number of recorded human sounds from YouTube, such as regular breathing, panting or coughing, were converted to spectrograms. The team then blocked certain parts of each one and prompted the AI to predict the missing portion, similar to the way LLMs learn to predict the next word in a sentence. The result was a foundation model, which, the researchers note, could be adapted for use in a wide variety of tasks.

In their case, the researchers used it to learn to detect tuberculosis or COVID-19. They then used a standard scale to compare the accuracy of HeAR with random guesses. They found it scored 0.739 on one data set and 0.645 on another for COVID-10 detection, and 0.739 on average for tuberculosis, which is better than results that have been obtained from other systems.

The research team acknowledges that much more work is required, but suggests that acoustic testing may someday make its way into doctor's offices, giving them yet another tool to diagnose patients with lung ailments.

By evaluating sound vibrations produced by the airflow induced within the lungs and bronchial tree during normal breathing as well as those produced by the larynx during vocalizations, doctors can identify potential disease-related abnormalities within the respiratory system. In AIP Advances, researchers demonstrate the efficacy of ultrasound technology to detect low-amplitude movements produced by vocalizations at the surface of the chest. They also demonstrated the possibility of using the airborne ultrasound surface motion camera to map these vibrations during short durations so as to illustrate their evolution.

The thorax, the part of the body between the neck and abdomen, provides medical professionals with a valuable window into a patient's respiratory health. By evaluating sound vibrations produced by the airflow induced within the lungs and bronchial tree during normal breathing as well as those produced by the larynx during vocalizations, doctors can identify potential disease-related abnormalities within the respiratory system.

But, among other shortcomings, common respiratory assessments can be subjective and are only as good as the quality of the exam. While the advent of multipoint electronic stethoscopes has helped in terms of identifying abnormalities during normal breathing, there remains a dearth of technological devices that can help characterize surface vibrations produced by vocalizations.

In AIP Advances, by AIP Publishing, a team of French researchers demonstrated the efficacy of ultrasound technology to detect low-amplitude movements produced by vocalizations at the surface of the chest. They also demonstrated the possibility of using the "airborne ultrasound surface motion camera" (AUSMC) to map these vibrations during short durations so as to illustrate their evolution.

"AUSMC is a new imaging technology that allows the observation of the human thorax surface vibrations due to respiratory and cardiac activities at high frame rates of typically 1,000 images per second," said author Mathieu Couade. "The technology shares the physical principle of conventional ultrasound Doppler imaging, but it does not require a probe to be applied on the skin."

The researchers tested the AUSMC on 77 healthy volunteers to image the surface vibrations caused by natural vocalizations with the aim of reproducing the "vocal fremitus" -- vocalization-induced vibrations on the surface of the body -- as typically analyzed during physical examination of the thorax. Surface vibrations induced were detectable on all subjects, they reported.

"The spatial distribution of vibrational energy was found to be asymmetric to the benefit of the right size of the chest, and frequency dependent in the anteroposterior axis," said Couade. "As expected, the frequency distribution of vocalization does not overlap between men and women, with the latter being higher."

Ongoing clinical trials will use the AUSMC to focus on the identification of lung pathologies. But the researchers are hopeful that the technology, coupled with artificial intelligence algorithms, could usher in a new era of thorax examination in which vibration patterns can be isolated. This would offer a much better window on respiratory health and enable better diagnoses of respiratory diseases.

In the journey towards a world free of Tuberculosis (TB), the crucial first step begins with identifying individuals affected by the disease.

Globally, around 1.3 million people died from TB in 2022, making it the second leading infectious killer after COVID-19, according to the World Health Organization (WHO).

However, many people with the disease, which is particularly prevalent in the Asia Pacific region and Africa, do not even get properly diagnosed.

Public health experts say the task of tracing these missing cases requires a three-pronged approach, involving community engagement, scaling-up the use of available technologies, and effective program management.

"By putting communities at the core, you ensure that they are fully involved in the process of making their villages TB-free," said Prabodh Bhambal, executive director of the Union South East Asia (USEA) Trust, at a webinar organized by Citizen News Service (CNS) this week (19 March).

The USEA Trust is an independent trust hosted by the International Union Against Tuberculosis and Lung Disease (The Union) in New Delhi, with a flagship project that aims to transform 1,000 villages into TB-free villages with support from the JSW Foundation, the social development arm of JSW Group, an Indian conglomerate whose businesses include steel, cement, automotive and paints.

The WHO estimates that India grapples with the world’s most extensive tuberculosis epidemic. In 2022, the country reported an incidence rate of 199 cases per 100,000 individuals in its population.

In Uganda, where there was a similar incidence rate of 198 cases per 100,000, the government is using mobile vans to conduct screenings in local communities as part of an awareness, testing and prevention campaign.

At the core of the campaign is the acknowledgment that relying solely on communities to visit health facilities doesn’t ensure uptake of services or effectively control TB at the community or household level.

The campaign emphasises the need for a collective desire for change, inspiring individuals to take action and voluntarily seek healthcare services. The aim is to enhance case-finding, address missing TB cases within communities, tackle treatment defaulting, and improve the use of prevention measures.

Stavia Turyahabwe, assistant commissioner for TB and Leprosy at Uganda’s Ministry of Health, says this approach has been highly effective. In 2022, more than 94,000 Ugandans were diagnosed with TB through the initiative, significantly contributing to improved disease detection rates, she told a two-day summit on TB and leprosy in Kampala this week (19-20 March).

However, she added that the ministry had yet to assess its impact on TB prevalence.

Harnessing technology, AI

Bhambal suggests that, by effectively harnessing current technologies for TB screening and diagnosis, a substantial portion of the undetected TB cases can be identified.

“In the small population of 5,000 people that we have screened so far under our project, we screened based on symptoms, used portable X-rays, and utilised an AI app.”

“Through this comprehensive approach, we have successfully detected cases of TB that would have otherwise been missed if we had relied solely on symptoms,” explained Bhambal, adding: “Technology plays a crucial role in finding these cases; we just need to find the right mix.”

Charles Olaro, director of clinical services at Uganda’s Ministry of Health, highlighted various innovations being employed in the country’s fight against TB, including GeneXpert technology, which rapidly diagnoses TB disease and drug resistance.

“We are not solely dependent on the microscope,” he said. “For any slides that test positive, we analyze them for drug resistance using the GeneXpert.”

Sriram Natarajan, co-founder of Indian diagnostics company Molbio Diagnostics, highlighted the limitations of microscopy in terms of detection.

However, he added that over the last decade, the WHO has approved molecular diagnostic tools capable of being deployed even in the doctor’s surgery.

He said these molecular tools boast sensitivity rates of up to 98 per cent, meaning that patients can be diagnosed at an early stage. However, despite these tools being available for about a decade, only about 25 to 30 per cent of TB cases globally are being diagnosed using them, according to Natarajan.

“We now have at least two available tools, but the uptake remains a major concern,” he told the CNS webinar.

“Both countries and their programs need to commit to implementing these tools at the primary level to ensure that everyone receives a molecular test as a confirmatory tool.”

Investment ‘crucial’

Natarajan says more commitment is needed from global funding agencies to focus on making these tools affordable and accessible to all.

“If we truly want to end TB by the target year of 2030, these interventions need to be scaled up and accelerated,” he added. “It’s crucial that these efforts are taken seriously.”

Lucica Ditiu, executive director of the Stop TB Partnership, told the CNS webinar: “It is possible to end TB. We see high-burden countries finding and treating TB.”

High-burden countries include India, Indonesia, Bangladesh, Nigeria, South Africa and Ethiopia.

“I want to say that, in many countries, private sector engagement is crucial to finding and treating all TB patients,” Ditiu added.

Guy Marks, respiratory medicine expert at the University of New South Wales and president and interim executive director of The Union, says TB must be treated as a public health problem, not merely an individual patient care issue.

“We must be brave and recognize that the current strategy to end TB in high-burden countries is not achieving the results we hope for,” he said.

“We need to change our approach if we are to win the fight against this infectious disease.”
