Why Is Europe Neglecting Chronic Respiratory Disease?
Published by the World Health Organization (WHO) Europe and the European Respiratory Society, the report found that 81.7 million people in the region are living with a CRD — including chronic obstructive pulmonary disease (COPD), asthma, and other lung diseases — and 6.8 million are newly diagnosed each year.
CRDs are the sixth leading cause of death in the WHO European region, with almost 400,000 dying from a CRD every year, nearly 80% of which are caused by COPD. However, most of these deaths are driven by preventable risk factors, primarily tobacco use and indoor and outdoor air pollution. The region has one of the highest rates of tobacco use, with one fourth of its adults being smokers, and more than 90% breathing air that is polluted with dangerous levels of particulate matter.
Answering the Whys
So why are CRDs so vastly underdiagnosed in Europe? Why do healthcare professionals not have the skills and expertise to identify them, as stated in the report? And what resources are required to bridge this gap?
On a policy level, the report noted an important paradox: Earlier progress led to a decline in CRD mortality, but this consequently led to reduced research funding and weakened surveillance. Without understanding the true burden of disease, it is difficult to advocate for increased policy focus and additional funding.
'Unfortunately, due to complexity with their definitions and absence of unanimously agreed targets, CRD surveillance and monitoring systems are not well designed,' the report said. 'Determining the real magnitude of the CRD burden is fundamental to identifying unmet needs at population level.'
'There has been a reduction in investment for CRD research compared with other noncommunicable diseases, where epidemiological studies have defined their global burden and priority actions; there are only a handful of population-based studies on CRDs,' the report continued.
Numerous health system and health worker challenges prevent the timely and correct diagnosis of CRDs. These include overlapping symptoms with other respiratory conditions and frequent comorbidities; limited healthcare provider knowledge and skills, especially at the primary healthcare level; inadequate access to diagnostic tools; lack of respiratory health specialists; and lack of awareness among patients, all of which can contribute to under- and misdiagnosis and thus delays in accessing treatment.
Respiratory Diseases Not so Glamorous
Philip Bardin, FRACP, PhD, professor and director of Lung and Sleep Medicine at Monash University and Medical Centre, Melbourne, Australia, and an international authority in the field of asthma and COPD, told Medscape Medical News that the impact of CRDs in the community has long been underappreciated.
Philip Bardin, FRACP, PhD
'We compete in the health space with other chronic diseases that use shock and awe tactics such as: 'You will have a stroke, a heart attack, or your foot will fall off' to gain public attention and funding,' he said. 'Historically, [there has been] poor advocacy by craft groups.'
Peter Burney, MD, professor of respiratory epidemiology and public health at the National Heart and Lung Institute at Imperial College London and honorary consultant physician at Royal Brompton Hospital, London, England, echoed Bardin's thoughts.
Peter Burney, MD
'Respiratory diseases are not glamourous; there is little sympathy for the old and the poor, and even less if they have been smokers. Asthma research has always been better funded with publicity that focuses on childhood [exposure to] smoking. Governments ought to be spurred on by the high costs of COPD in [terms of] direct costs of hospitalization.'
He cited a 2015 study published in the journal Chest that reviewed population-based prevalence studies that measured lung function and looked for undiagnosed COPD.
Undiagnosed COPD was high in almost all locations studied, he said.
'London (UK) had a high prevalence of disease, but approximately 80% [of detected COPD cases were] undiagnosed. The why is complicated,' he said. 'Firstly, COPD is a very recent invention, and chronic obstructive pulmonary disease may mean more to average Americans than others. We used to call it bronchitis or chronic obstructive bronchitis.'
The Primary Care Challenge
With a shortage of respiratory specialists, some countries are expanding the role of primary healthcare to include the identification of CRDs, joining many other countries that have for decades put primary providers on the front line of respiratory medicine.
But while spirometry is one of the essential tools for diagnosing and monitoring CRDs, it remains limited as it requires well-trained staff, reliable equipment, and standardized procedures.
'Spirometry is not commonly done in general practice, and it was more or less stopped during COVID. It is difficult to do well, and quality assurance is a problem,' Burney said. 'If a practitioner is not using skills learned in medical school and in early training, the skill in interpreting spirometry results soon atrophies. In addition, primary care is feeling a bit put upon, and it is difficult in these circumstances to launch a whole new initiative.'
Promise in Education
Expanding education and using innovative technology appear to hold some promise in overcoming such challenges.
The report cited Spain, which has a new e-learning program, Spirometry Simplified, for primary healthcare providers to expand their knowledge. Also, Italy and Spain are testing tele-spirometry. Here, a technician remotely controls from within a hospital a computer with spirometer software that is connected to a primary care patient. The aim is to help overcome the issue of poor-quality spirometry use in primary care.
'Solutions need to come via patient participation and teamwork by doctors, nurses, and others to improve care. Waiting for governments and bureaucrats to solve problems will take us nowhere,' Bardin said. 'Doing better what we've always done will get us what we've always had.'
Bardin and Burney reported having no relevant financial relationships.

Microplastics found in human semen, follicular fluid
Scientists have detected microplastics — the tiny and pervasive fragments now found in our seas, drinking water, food and, increasingly, living tissue — in human semen and follicular fluid, according to new research. A small group of 25 women and 18 men participated in the research, published Tuesday in the journal Human Reproduction. Microplastics were detected in 69% of the follicular fluid samples and 55% of the seminal fluid samples. Follicular fluid is the liquid that surrounds an egg in an ovarian follicle. The research is an abstract — a short summary of completed research — and has not yet been peer reviewed. It was presented Tuesday in Paris at the 41st Annual Meeting of the European Society of Human Reproduction and Embryology. 'Previous studies had already suggested this possibility, so the presence of microplastics in the human reproductive system is not entirely unexpected,' said lead research author Dr. Emilio Gómez-Sánchez, director of the assisted reproduction laboratory at Next Fertility Murcia in Spain, in a statement provided to the press. 'What did surprise us, however, is how widespread it is. This is not an isolated finding — it appears to be quite common.' Microplastics are polymer fragments that range in size from less than 0.2 inches (5 millimeters) to 1/25,000th of an inch (1 micrometer). Polymers are chemical compounds with long chains of large and repetitive molecular units called monomers, and are known for being flexible and durable. Most plastics are synthetic polymers. Plastics smaller than the measurement criteria for microplastics are considered nanoplastics, which are measured in billionths of a meter. 'Microplastics primarily enter the body through three routes: ingestion, inhalation, and skin contact,' Gómez-Sánchez said. 'From there, they can enter the bloodstream, which then distributes them throughout the body, including to the reproductive organs.' In previous studies, the fragments have also been detected in various body parts or fluids including the lungs, placenta, brain, testicles, nose tissue at the base of the brain, penises and human stool. 'Decades of studies and the (US Food and Drug Administration) agree that microplastics are not a threat because exposure is extremely low and they are non-toxic,' said Dr. Chris DeArmitt, founder of the Plastics Research Council, via email. However, while there is little to nothing known about the potential effects of microplastics on human health, chemicals used in plastic production — that often leach from plastics — are linked with health risks including hormonal disruptions, certain cancers, respiratory diseases and skin irritation. The research participants were patients and donors at Next Fertility Murcia. The women were undergoing egg retrieval, formally known as follicular aspiration, for assisted reproduction, while the men were undergoing semen analysis. The authors stored and froze the samples in glass, then incubated them for two days before analyzing them using an imaging technique combining microscopy and infrared laser. The research team also analyzed the containers used to collect and store samples to ensure they hadn't been contaminated with microplastics. The abstract doesn't disclose what materials the collection containers were made of. Imaging revealed nine types of microplastics in the reproductive fluids. Over 50% of the follicular fluid samples contained polyamide (PA), polyurethane (PU) and polyethylene (PE), while polytetrafluoroethylene (PTFE) and polyethylene terephthalate (PET) were discovered in over 30% of the follicular fluid samples. Polypropylene (PP), polyvinyl chloride (PVC) and polylactic acid (PLA) appeared in over 20% of the follicular fluid samples. In the semen samples, 56% contained PTFE. Synthetic polyamide is commonly known as nylon, often used in textiles, plastics and automotive parts. Polyurethane is commonly used in coatings, foams and adhesives for furniture, construction, automotive parts, footwear and more. Polyethylene and polypropylene are often found in packaging, construction uses and consumer goods, such as toys and kitchenware. The plastic PTFE is widely used in nonstick cookware, while PET is found in many food and beverage containers. Polyvinyl chloride is often used in the construction, packaging and medical industries, while PLA is primarily found in food packing, medical implants and 3D-printed objects. In most samples, the researchers found only one or two particles, but they detected up to five in others, Gómez-Sánchez said. Microplastic concentrations were higher in follicular fluid than in semen. However, the overall concentrations of microplastics in both fluids were relatively low when compared with the concentrations of non-plastic particles. The abstract didn't disclose what those non-plastic particles were. 'Sadly, (the findings) are not surprising,' said Dr. Matthew J. Campen — a researcher who helped lead the discoveries of microplastics in the brain and testicles — via email. Though the research is preliminary, it does 'set the stage for more advanced studies of the relationship between plastics exposure and reproductive fitness,' added Campen, who wasn't involved in the study and is a regents' professor of pharmaceutical sciences at the University of New Mexico. The research affirmed previous studies that had found microplastics in these reproductive fluids, and yet again raises important questions, including how these microplastics are absorbed in the intestine then transported to the gonads, Campen said. 'This suggests a very natural mechanism is being hijacked,' he added. 'It would also be important to assess plastics in the nanoscale range.' People trying to conceive naturally or via in vitro fertilization may not need to be concerned about the findings, as they are only preliminary for now, Gómez-Sánchez said. 'We don't know if they have a direct effect on the capacity of a couple to conceive and carry a baby to term,' he added. 'Reproduction is a complex equation, and microplastics are a variable in this equation.' The findings also can't yet be linked to more general health outcomes, experts said. 'So far, the effects of microplastics on humans have been mainly extrapolated from animal studies, where microplastics were administered at high concentrations,' Gómez-Sánchez said. 'We currently lack direct evidence regarding their impact on humans.' Betsy Bowers, executive director of the EPS Industry Alliance, echoed these disclaimers and noted that the animal research results aren't indicative of harm at regular exposure levels. The EPS (expanded polystyrene) Industry Alliance is a North American trade association representing the EPS industry. The finding that follicular fluid contained more microplastics than semen may be circumstantial, Gómez-Sánchez added, because the study group was small. However, when an ovary is stimulated for assisted reproduction, blood flow to the ovary increases, which may deliver more microplastics to the ovary, he explained. Additional research is needed to identify the types and quantities of microplastics that could cause health problems, said Dr. Ranjith Ramasamy, a consultant urologist at Jumeirah American Clinic in Dubai. Ramasamy, who wasn't involved in the study, led the research that found microplastics in penises. 'The plan is to increase the number of cases and conduct a survey on lifestyle habits in order to determine if any of these habits are linked to higher concentrations of plastics found in the ovaries and seminal plasma,' Gómez-Sánchez said. Gómez-Sánchez and the other researchers also plan to explore whether the presence of microplastics in reproductive fluids affects the quality of sperm and oocytes, he said. Oocytes are cells in ovaries that form an ovum, a mature female reproductive cell that can divide to create an embryo upon fertilization by sperm. The significance of the findings isn't yet clear, but they should be considered an additional argument in favor of avoiding the use of plastics in our daily lives, said Dr. Carlos Calhaz-Jorge, professor of obstetrics and gynecology at the University of Lisbon in Portugal, in a news release. Calhaz-Jorge wasn't involved in the research. Given the ubiquity of plastics, avoidance can be challenging, said Dr. Philip Landrigan, a pediatrician and director of the Program for Global Public Health and the Common Good at Boston College, via email. In addition to reducing obvious uses of plastic, you can also avoid using plastic cutting boards and eating ultraprocessed foods. Also limit drinking water from plastic bottles, microwaving food in plastic containers and consuming hot food from plastic containers, Ramasamy said. Food can be stored in glass, stainless steel or bamboo instead of plastic. But 'the conversation needs to shift — immediately — to policymakers,' Campen said. 'Hoping that individual choices can make a difference has been clearly a losing strategy. Federal governments around the world need to make major changes to waste management and recycling policies.' Annual plastic production by weight has increased by 250 times in the past 75 years and is on track to triple again by 2060, Landrigan said. 'To reduce plastic pollution and safeguard human health, it will be essential that the Global Plastics Treaty that is currently in negotiation at the United Nations impose a global cap on plastic production,' Landrigan, who wasn't involved in the research, added. 'But smart governments can act now,' Campen urged. Sign up for CNN's Life, But Greener newsletter.

Minnesota hospitals brace for potential cuts after Senate passes Trump's "big, beautiful bill"
President Trump's massive tax and spending plan is a step closer to his desk after the U.S. Senate narrowly approved its version of the bill Tuesday morning. In response, protesters rallied outside the state health department in St. Paul. They demonstrated against what could be more than $1 trillion in cuts to programs like Medicaid. At Hennepin Healthcare, nearly 100,000 people use that insurance option. "I am kind of shocked to be honest," Joel Williams, a Medicaid user, said. Williams served as a Chicago police officer for 25 years. He is now disabled with severe asthma, is a kidney transplant recipient and he depends on Medicaid and Medicare. When asked if he was scared about cuts, Williams said, "Definitely. This is major, this is major major. I never thought after years of working... It's unbelievable to me. I'm trying to grasp it." Interim Hennepin Healthcare CEO Dr. Thomas Klemond is also scared. "We are looking at 100 million or more potential losses," Klemond said. "These are projections and the bills are still evolving. We are looking at, can we keep doing what we are doing?" Klemond says as Minnesota's largest safety net hospital, they will continue to treat everyone regardless of ability to pay. He adds that as people lose insurance, emergency room visits will soar. That means other hospital programs, even Hennepin Healthcare's renowned poison center and its burn unit, could be eyed for cuts. Klemond said. "Can we continue doing all of the things we are doing? Can we continue doing most of the things we are doing? Can we survive?" Klemond said. At Hennepin Healthcare and at hospitals around the state and country, this latest vote just raises the level of uncertainty over how they are going to be able to care for patients in the future. Klemond says he expects to start losing Medicaid reimbursements as soon as January 2026 in Minneapolis. There are concerns that some hospitals in small communities will close down altogether. The major health provider for rural Minnesota says they're still processing what is in the bill.
