In 2020, scientists working on injury analytics expanded to COVID-19 epidemiology to help create and monitor the NBA bubble. Dr. Christina Mack, an epidemiologist with IQVIA Real World Solutions, talks with Dr. Josh Sharfstein about how the team continues to monitor the health and safety of players and staff, and some of the findings with real-world implications such as how long people can shed COVID-19 virus, if people with asymptomatic infections are less likely to transmit COVID, and whether boosters really work.

The planetary health crisis can’t be ignored in hospitals where patients are sick from climate-driven things like asthma from air quality emergencies, COVID-19 from a zoonotic spillover event, and cardiovascular complications from heat waves. Chris Lemon, an ER doctor and Bloomberg Health Initiative fellow who focuses on the intersection of climate change and health, talks with Stephanie Desmon about his work bringing planetary health dialogue to hospital staff while also looking at ways health systems can lower their massive carbon footprints.
From mushrooms to microscopic organisms, fungi represent a serious—and still relatively unexplored—threat to human health. Dr. Arturo Casadevall returns to the podcast to talk about his new book, What If Fungi Win? which looks at why certain fungal infections take off, why they’re so hard to treat, and why we will most certainly see more of them with climate change and treatment-resistant strains.

More than a decade after electronic cigarettes became broadly available in the United States, their merits are still being debated. Do these products help people quit smoking? How serious are the health risks associated with these products? In a two-part series, we hear from two researchers in tobacco control about their views. In part two, Stan Glantz, the Truth Initiative Distinguished Professor of Tobacco Control at the University of California San Francisco talks with Dr. Josh Sharfstein about his research into the harms of electronic cigarettes and the dangers of "dual use" of electronic cigarettes and traditional cigarettes. In an epilogue, Public Health On Call audio producer Matt Martin talks with Lindsay Smith Rogers about his personal history of tobacco use – including his efforts to quit with electronic cigarettes.

Virologist Dr. Andy Pekosz and public health veterinary expert Dr. Meghan Davis return to the podcast to talk with Stephanie Desmon about what we’ve learned so far from viral sequencing of H5N1, its presence in milk, what we know about infections in humans, the status of the overall response to a major pathogen of concern on the heels of COVID-19, and more.

An alarming and dangerous syphilis surge across the Great Plains Region, an area spanning North Dakota, South Dakota, Nebraska, and Iowa, has prompted tribal officials to urge HHS Secretary to declare a public health emergency. Dr. Meghan Curry O’Connell, chief public health officer at the Great Plains Tribal Leaders Health Board and a member of the Cherokee Nation, talks with Lindsay Smith Rogers about the outbreak and why public health officials are struggling to respond.

In part one of a two-part series about the crisis of health care for immigrants and refugees at the U.S.-Mexico border, Dr. Janine Young, a pediatrician at the University of California, San Diego, talks with Stephanie Desmon about the tenuous situation for children and families. More and more people are showing up at the border in poor health—dehydrated, malnourished, some severely injured and many traumatized—without any adequate care to meet them. They talk about the immigration policies that have led to a system ill-equipped to properly triage and treat the children and families seeking refuge in the U.S., and the misconceptions around people who are fleeing for their lives.
Methadone is a highly effective treatment for substance use disorder but strict regulations like daily clinic visits have led to its nickname, “liquid handcuffs.” Dr. Yngvild Olsen, director of the Center for Substance Abuse Treatment at the Substance Abuse and Mental Health Services administration, talks with Lindsay Smith Rogers about new federal regulations that expand access to this life saving medication. They talk about how the COVID era showed that changes can make methadone much easier to prescribe and access, and how these updates are part of a critical cultural shift towards making substance use treatment more reasonable, equitable, and compassionate.

The presence of infectious diseases can be picked up through wastewater surveillance but how can this data be useful in predicting future outbreaks? Dr. Dylan George, director of the Center for Forecasting and Outbreak Analytics at the CDC, talks with Dr. Josh Sharfstein about how the Center’s forecast for the 2023-2024 respiratory virus season performed and the role of wastewater surveillance as part of a multifaceted approach to aggregating data.

There’s a lot of research around Type 2 diabetes that has informed patient care when it comes to diagnosis, treatment, and lifestyle management. But much less is known about Type 1, long mislabeled “childhood diabetes.” Johns Hopkins epidemiologists Elizabeth Selvin and Michael Fang talk with Stephanie Desmon about new research debunking a lot of previously held assumptions about Type 1 diabetes, the prevalence of adult onset and correlation with obesity, and why different approaches to diagnosis and management are necessary. They also discuss the cost of insulin and why more research is needed around medications like Ozempic for Type 1 diabetes.
Cigarette butts are the most littered object in the world. With their plastic filters and toxic substances, they are a significant source of contamination for soil and water. Grazi Grilo, a researcher at the Global Institute for Tobacco Control, talks with Stephanie Desmon about her work quantifying the scope of the problem, and why some of the very things that make cigarettes so environmentally hazardous also provide enormous benefits for the tobacco industry.Read more about her work here: https://publichealth.jhu.edu/institute-for-global-tobacco-control/2024/assessment-of-littered-cigarette-butts-in-brazil-informs-strengthening-of-global-treaty
