A hole in your throat is nothing to sneeze at, as shown by a case report recently published in BMJ Case Reports. And the case report showed the dangers of pinching your nose and closing your mouth in an attempt to stifle a sneeze. A man in his 30s tried doing this and was left with a hole is his trachea, which can be a hole lot of trouble.
This man who had a history of allergies was wearing a seat belt while driving his car when he felt the need to sneeze and in a pinch tried to keep the sneeze from exiting from either his nostrils or his mouth. This led to quite a pressure-filled situation. Normally, sneezing can generate a pressure of one to two kilopascals in the upper airways which, in turn, can blast air and accompanying gunk out through your nose and mouth. But guess what happens when you pinch your nose shut and keep your mouth closed at the same time? Rather than rushing out of these holes, the air has no place to go. That can build up pressure your the upper airways that is up to 20 times higher than what a released sneeze would generate.
After this sneezus interruptus, the man began experiencing severe neck pain and eventually ended up in the emergency department of Ninewells Hospital in Dundee, UK. The four authors of the case report (Rasads Misirovs, Gary Hoey, Calum Carruthers and Samit Majumdar) work at this hospital. There doctors found the man’s neck to be swollen on both sides. An X-ray of his neck revealed evidence of air where it wasn’t supposed to be, and a CT of the neck and chest with contrast showed a 2 mm by 2 mm by 5 mm in his trachea, otherwise known as his windpipe.
In this episode, my guest is Dr. Robert Lustig, M.D., neuroendocrinologist, professor of pediatrics at the University of California, San Francisco (UCSF), and a bestselling author on nutrition and metabolic health. We address the “calories in-calories out” (CICO) model of metabolism and weight regulation and how specific macronutrients (protein, fat, carbohydrates), fiber and sugar can modify the CICO equation. We cover how different types of sugars, specifically fructose, sugars found in liquid form, taste intensity, and other factors impact insulin levels, liver, kidney, and metabolic health. We also explore how fructose in non-fruit sources can be addictive (acting similarly to drugs of abuse) and how sugar alters brain circuits related to food cravings and satisfaction. We discuss the role of sugar in childhood and adult obesity, gut health and disease and mental health. We also discuss how the food industry uses refined sugars to create pseudo foods and what these do to the brain and body. This episode is replete with actionable information about sugar and metabolism, weight control, brain health and body composition. It ought to be of interest to anyone seeking to understand how specific food choices impact the immediate and long-term health of the brain and body.

In this episode, I am joined by Dr. David Sinclair, tenured Professor of Genetics at Harvard Medical School and an expert researcher in the field of longevity. Dr. Sinclair is also the author of the book Lifespan: Why We Age & Why We Don’t Have To, and the host of the Lifespan Podcast, which launches January 5, 2022. In this interview, we discuss the cellular and molecular mechanisms of aging and what we all can do to slow or reverse the aging process. We discuss fasting and supplementation with resveratrol, NAD, metformin, and NMN. We also discuss the use of caffeine, exercise, cold exposure, and why excessive iron load is bad for us. We discuss food choices for offsetting aging and promoting autophagy (clearance of dead cells). And we discuss the key blood markers everyone should monitor to determine your biological versus chronological age. We also discuss the future of longevity research and technology. This episode includes lots of basic science and specific, actionable protocols, right down to the details of what to do and when. By the end, you will have in-depth knowledge of the biology of aging and how to offset it. #HubermanLab #DavidSinclair #Longevity
A new study in Nature reports an AI-driven advance in biotechnology with implications for drug development, disease detection, and environmental monitoring. Scientists at the Institute for Protein Design at the University of Washington School of Medicine used software to create protein molecules that bind with exceptionally high affinity and specificity to a variety of challenging biomarkers, including human hormones.
Notably, the scientists achieved the highest interaction strength ever reported between a computer-generated biomolecule and its target.
Senior author David Baker, professor of biochemistry at UW Medicine and Howard Hughes Medical Institute investigator, emphasized the potential impact: “The ability to generate novel proteins with such high binding affinity and specificity opens up a world of possibilities, from new disease treatments to advanced diagnostics.”
Nearly two in five U.S. adults have high cholesterol, according to the Centers for Disease Control and Prevention (CDC). Untreated, high cholesterol can lead to heart disease and stroke, which are two of the top causes of death in the U.S. Worldwide; cardiovascular diseases claim nearly 18 million lives every year, according to the World Health Organization.
A new vaccine developed by researchers at The University of New Mexico School of Medicine could be a game-changer, providing an inexpensive method to lower “bad” LDL cholesterol, which creates dangerous plaques that can block blood vessels.
In a recent study published in npj Vaccines, a team led by Bryce Chackerian, Ph.D., Regents’ Professor in the Department of Molecular Genetics & Microbiology, reported the vaccines lowered LDL cholesterol almost as effectively as an expensive class of drugs known as PCSK9 inhibitors.
Analysis of human brain tissue reveals differences in how immune cells behave in brains with Alzheimer’s disease compared to healthy brains, indicating a potential new treatment target.
University of Washington-led research, published in August, discovered microglia in the brains of people with Alzheimer’s disease were in a pre-inflammatory state more frequently, making them less likely to be protective.
Microglia are immune cells that help keep our brains healthy by clearing waste and preserving normal brain function.

Several women have filed medical malpractice lawsuits against a southern California plastic surgeon well known on Instagram, alleging that they endured botched surgeries, unexpected scarring and serious infections.
As reported by the Los Angeles Times, the series of lawsuits allege that Dr. Arian Mowlavi degraded the women by requiring them to take off all of their clothes during an examination, touching their bodies without consent and attempting to sell them additional procedures like breast augmentations and body sculpting.
Mowlavi, who was based in Laguna Beach, called himself “Dr. Laguna” and a “renowned body sculptor” while charging 10s of thousands for procedures that his patients allege were done sloppily or, in some cases, not by Mowlavi at all.
Almost half the people known to have contracted COVID-19 in Africa are now living with the effects of long COVID, according to a comprehensive review of previous studies and analysis, covering data from a total of 29,213 people.
Incidence rates in Africa, though, are well above any of these other estimates. Why that is the case is unclear. In low-income countries, estimates of the incidence of long COVID vary greatly, due to hidden infections and the difficulty of accessing tests.
