You know them, you’ve seen them, you may even use them. They’re WMD-wearable medical devices like the FitBit, the Apple Watch, and the Aura ring, and the one-inch square discs affixed on people’s upper arms monitoring blood glucose or delivering medication. These are examples of an expanding array of wearable and implantable medical devices or BioMEMSs (biomedical microelectromechanical systems) that have transformed modern healthcare. These wearables enable non-invasive, real-time monitoring of heart rate, heart rhythm, blood pressure, sleep, blood glucose, and blood oxygen saturation. Implantable BioMEMS range from continuous glucose monitoring and insulin delivery to intraocular pressure monitoring. Other uses include programmable drug delivery for antibiotics, neuro-modulation for chronic pain and Parkinson’s disease, and the list goes on.

The eye's posterior chamber, from the back of the lens through the gel-like vitreous humor to the retina’s neural network and blood vessels, is a marvel of biologic engineering. It translates light into electrical impulses, enabling vision. Age and disease not only produce benign flashers and floaters but also the more serious vitreous and retinal detachment. They also contribute to macular degeneration and proliferative retinopathy. All of these conditions once resulted in blindness, but today’s intraocular lasers and vascular growth factor inhibitor injections can preserve a patient’s vision. We take a closer look at all of the above on this episode.

The innumerable songs of heartache by female artists that top the R&B, Rock and Country music charts tell of the emotional heartbreak of lost love. But the literal, physical broken heart is a profoundly underappreciated aspect of women’s health. Heart disease is the number one cause of death for women in the U.S., more lethal than all forms of cancer combined. By 2050, heart disease will affect more than 22 million women with nearly a third between the ages 22 to 44. On this episode, we discuss women’s heart health from pregnancy through old age.

The roots of urgent care trace back to the industrial clinics of the early 20th century designed to treat injured workers quickly and minimize downtime. The urgent care model re-emerged in the 1970s as a response to overcrowded emergency departments and the inability of primary care offices to handle acute, non-life-threatening issues such as walk-ins or after-hours care. Initially met with skepticism and branded by many as "doc-in-a-box,” today urgent care is a $50 billion industry in the U.S. with more than 11,000 centers nationwide. Urgent care is the go-to for routine needs as 45% of young adults lack a primary care provider (PCP). Urgent care may be a better option than the emergency room, but is it better than primary care if primary care was revitalized? We examine that question and more on this episode.

Most rashes are benign. If they are viral, they resolve spontaneously, and if they are bacterial they may require antibiotics. However, some rashes have been more elusive to understand and treat. These more chronic skin rashes are long-lasting, often inflammatory disorders requiring ongoing management to control symptoms like itching, redness, and pain. Common types include eczema, psoriasis, acne, and rosacea. Their underlying cause is complex, driven by autoimmune responses, genetics, and environmental triggers. These conditions significantly impact quality of life, necessitating personalized, long-term treatment.

Cataracts, which are the age-related changes of the eye’s natural lens, are the leading cause of reversible blindness worldwide and among older adults in the U.S. As proteins in the lens break down over time, they cause the lens to be less transparent and less able to change its shape. The lens can’t contract into a ball for near vision or flatten for distant; images become cloudy, blurry, less bright, and less colorful. Untreated advanced cataracts can lead to total blindness, which amazingly can still be reversed with surgery. Current estimates are that four million cataract surgeries are performed annually in the U.S., and the surgery is considered the safest invasive procedure done on humans. On this episode, we'll take a deep dive into the most common surgery performed in the U.S. today.

The US rural healthcare crisis is a quiet emergency affecting roughly 60 million people — one-fifth of the population — who face higher mortality rates, systemic hospital closures, and severe specialist shortage. Over 700 rural hospitals (roughly 30% of the national total) are currently at risk of closing due to financial shortfalls. Since 2005, more than 190 rural hospitals have closed while another 25% have closed their maternity wards. While 20% of Americans live in rural areas, only 10% of US physicians practice there. Rural residents face higher rates of premature death from heart disease, cancer, and stroke compared to their urban counterparts. Suicide rates are significantly higher in rural areas, particularly among adult men and children. While only one-third of motor vehicle accidents occur in rural areas, they account for two-thirds of all accident-related deaths. This episode explores the rural healthcare crisis.

The facts are staggering. Lung cancer remains the number one cancer killer of both men and women. 230,000 new lung cancer diagnoses are expected in the US this year. The average annual cost of treating advanced or metastatic lung cancer is astronomical, often exceeding $200,000 per year. Lung cancer screening with low-dose CT scans is severely underused in the U.S. with less than 20% of the millions of eligible high-risk former and current smokers getting tested. Lung cancer screening works. It’s safe and effective. It saves lives. It saves healthcare dollars as the cost of treating advanced cancer continues to skyrocket. On this episode, we'll try to understand how to increase use of this inexpensive test that can save more lives and money than any other in healthcare.
