The use of sound or acoustic energy in medicine has evolved from the ancient diagnostic method used by ⁠Hippocrates by placing his ear to the chest. However, we had to wait 2,000 years for the invention of the ⁠stethoscope⁠. Today, acoustic energy is used in diagnostic imaging called ultrasound that has revolutionized obstetrics and cardiology, while therapeutic applications of sound have resulted in shockwave lithotripsy to break up kidney stones, destroy tumors. This episode explores new uses of sound energy.

Great trauma systems do not prevent trauma; they limit the carnage, disability, and chaos that are its consequence. Preventing trauma is the work of public policy and organizations like the Georgia Trauma Foundation. Seat belt laws, helmet laws, and air bag requirements have saved literally millions of lives. But technology, policy, education, and awareness have limits. Reckless driving, driving while intoxicated, and the use of cell phones while driving are some of the root causes that speak to a crisis of personal accountability and the inherent irrationality of the human condition. Worse, they decry hubris, selfishness, and lack of civility that jeopardizes not just the driver’s life, but the passengers and bystanders who are placed at risk.

If you’ve ever gone with your gut to make a decision or felt butterflies in your stomach when nervous, you’re likely getting signals from an unexpected source: your second brain. Hidden in the walls of the digestive system, this brain in your gut is revolutionizing medicine’s understanding of the links between digestion, mood, behavior, health, and even the way you think. Add increased understanding of the influence gut bacteria has on disease and health, called our microbiome, and we may begin to grasp that our gut or gastrointestinal system has a much more complex role in human health beyond nutrition and energy, as we learn on this episode.

The hormonal chaos women experience month after month from menarche through menopause is due to natural, fluctuating levels of hormones like estrogen and progesterone that can impact mood, energy, and even physical health. These hormonal shifts affect internal chemicals called neurotransmitters that can lead to mood swings, anxiety, brain fog, and fatigue. They may be a normal part of the female life cycle that spans Menarche, Menstruation, Pregnancy, Postpartum, Perimenopause and Menopause, but they are often referred to as the “stages of chaos” as we'll hear more about on this episode.

The 2002 Verizon advertising campaign launched the slogan: Can you hear me now? The phrase resonated not only because of the universal experience of poor reception quality of cellular networks, but due to an emerging zeitgeist of disaffection with modernity, technology, impersonal communication, and isolation. Healthcare consumers embody this frustration, propelling them to call in to “The Weekly Check-Up Podcast.” The pain points are myriad: poor provider communication, confusing insurance benefits, fear, vulnerability, and feelings of being dismissed or unheard. It all results in dissatisfaction with care and a significant emotional toll.

Heart failure has a long history in medicine. It began with the Greek physician Galen in 200 AD. In 1300, Ibn Nafis established the foundation upon which William Harvey made his revolutionary conclusion some 400 years later. Harvey noted that blood circulates continuously left to right through the lungs by the pumping or propelling action of the cardiac muscle, thus making the heart the center of the cardiovascular system.

Today, heart failure remains a major public health problem and a leading cause of death affecting 26 million people worldwide. On this episode, Dr. Feinberg explores heart failure management with two specialists: Dr. Ugo Egalum, a cardiologist, and Dr. Kyle Thompson, a cardiothoracic surgeon.

The all-too-familiar topic of school shootings remains the focus of endless debate. While we all wring our hands at the perceived inability to stop this horror, there are folks focused on what can be done to limit the death and injury while the problem itself remains intractable, with more than 43,000 children exposed in 2022 alone. One such shooting occurred less than 60 miles from Dr. Feinberg’s home in Atlanta on September 4, 2024 at Apalachee High School in the city of Winder, Georgia. On this episode, Dr. Feinberg talks to first responders Kevin Locke, who was on site at Apalachee High School, and Crystal Shelnutt, of the Georgia Trauma Commission, to understand what can be done to limit the carnage of school shootings and other types of traumatic injury. The interview also includes perspectives from Cheryle Ward, executive director of Georgia Trauma Foundation, which invests in trauma care in Georgia, including the Stop The Bleed campaign, which works to get Stop The Bleed kits in schools throughout the state.

Vision is the dominant of the five senses the body uses to interpret its surroundings. The organ of vision is the eye which is composed of a series of lenses and spaces that give focus to images, just as a camera does. It is composed of the cornea, lens, and the aqueous and vitreous humor, each of which contribute to perfecting the focus of the light received by the retina, analogous to the film of the camera. Given how critical the eye is to the understanding of our surroundings, it is heavily protected by a bony orbit and allowed near omni-directional movement made possible by six eye muscles and three of the 12 cranial nerves. Vision can be disturbed if the light can’t be focused, if the retina can’t receive the light, if the optical nerve is impaired, or if the eye muscles cannot move synchronously. All of which require an intact blood supply and orbit. On this episode , we'll be joined by Dr. Joseph Hyatt, an ophthalmologist and eye specialist, as we talk to callers about varied issues impairing their vision.
