A story of esophageal variceal rupture
An excerpt from 50 Years in the OR: True Stories of Life, Loss, and Laughter While Giving Anesthesia. Chronic long-term alcoholism causes many health problems, not the least of which is cirrhosis of the liver. In advanced cases of cirrhosis, the liver becomes full of scar tissue and its many functions are then impaired, causing […]Find jobs at Careers by KevinMD.com.

How could a patient die from anesthesia for a colonoscopy?
Every death related to anesthesia is a tragedy; even more so when a minor procedure such as a colonoscopy leads to a completely unexpected death. Everyone knows that open heart surgery carries a mortality risk, but few of us walk into the hospital for a colonoscopy thinking that death is a plausible outcome. We know […]Find jobs at Careers by KevinMD.com. Search thousands of physician, PA, NP, and CRNA jobs now. Learn more. (Source: Kevin, M.D. - Medical Weblog)

Cool Images: Bewitching Bacteria
Some bacteria benefit us as part of our microbiome—the vast collection of microorganisms that live in and on our bodies—while others can make us sick. Whether helpful or dangerous, bacteria can appear colorful and striking under a microscope. These photos provide just a small peek into the incredible diversity of these microbes.

Stomach Cancer Stage 4 Treatment
Stomach cancer stage 4 is a complex diagnosis. It is the stage of cancer that requires specific treatment options.
Is surgery an option for patients with stomach cancer stage 4?
Stage 4 stomach cancer is characterized by rapid tumor growth, metastasizing to regional lymph nodes and distant organs (liver, bones, pancreas, less often lungs). With the development of metastases in other organs, characteristic symptoms occur such as jaundice and liver failure with liver damage, ascites with metastases in the peritoneum, bowel obstruction with metastases in the small intestine, etc.
Therefore, at the advanced stages, ga...

A little less nervous about Covid
The rare and potentially lethal neurological disorder, Guillain-Barré syndrome, is not triggered by Covid nor by vaccination against Covid, recent research suggests.
There was concern during the early months of the Covid pandemic based on anecdotal evidence that there had been an increase in the incidence of a potentially lethal neurological disorder known as Guillain-Barré syndrome (GBS). In this disease, the body’s own immune system attacks peripheral nerves causing numbness, pain, and paralysis. It can be fatal if not treated promptly.
Pain and numbness often spread upwards from the soles of the feet or the hand...

Training in psychiatry would give me the opportunity to understand suicide far better
An excerpt from Becoming a Doctors’ Doctor: A Memoir.

Then, after a series of general medicine rotations, I started an elective in gastroenterology. This was a […]Find jobs at Careers by KevinMD.com.

Fight Aging! Newsletter, January 18th 2021
In this study, Desferal, deferoxamine mesylate for injection, which is approved for the treatment of acute iron intoxication and chronic iron overload, was used to explore the beneficial effects on preventing aging-induced bone loss and mitigating dysfunction of aged BMSCs. High-dose Desferal significantly prevented bone loss in aged rats. Compared with controls, the ex vivo experiments showed that short-term Desferal administration could promote the potential of BMSC growth and improve the rebalance of osteogenic and adipogenic differentiation, as well as rejuvenate senescent BMSCs and revise the expression of stemness/se...

A Continued Focus on Metformin, a Demonstrably Poor Approach to Treating Aging
Metformin is a poster child for the way in which much of the aging research community is focused on approaches to aging that cannot possibly achieve more than a very modest slowing of degeneration, and where the existing evidence strongly suggests that those tiny positive outcomes will be unreliable at best. Metformin is a way to tinker with the operation of a damaged metabolism, not a way to repair that damage. As a calorie restriction mimetic, the animal data shows that it compares very poorly to calorie restriction itself. We know that calorie restriction doesn't do anywhere near enough for human longevity. This is not ...

Can I take something to prevent colorectal cancer?
Colorectal cancer (CRC) is the second leading cause of cancer death in the United States. There is compelling evidence that screening to detect CRC early to find and remove precancerous polyps can reduce CRC mortality. However, screening has associated harms, including procedural complications, and inherent limitations. For example, colonoscopy, the most common screening tool in the US, is less effective in preventing cancers of the right, or ascending side, of the colon compared with cancers of the left, or descending, side of the colon.
Moreover, only 60% of US adults recommended for screening actually follow through. Ev...

The Year When Everything Changed: Covid, Self Care and High Tech Innovation In Medicine
By HANS DUVEFELT
Life as we knew it and medicine as we had viewed it shapeshifted so dramatically in the past year that it is still hard to believe.
Medicine has started to move from an in-person only profession to one that finally recognizes that clinical assessment and treatment have fewer boundaries than people assumed. A patient of mine with newly diagnosed mastocytosis had a productive first consultation with an immunologist hundreds of miles away right from her own living room.
Efficiency increased when we could handle straightforward clinical issues electronically, even over the telephone, and still get...

“VRx”: A Medgadget Book Interview with Author Dr. Brennan Spiegel
In the recently released science-fiction novel Ready Player Two, protagonist Wade Watts spends the majority of the book inside a virtual reality universe called the “OASIS”. Though the OASIS is merely a simulation consisting of computer-generated imagery, immersive sound, and gesture-based interaction, it has a profound impact on reality. It’s a place where one loses the sense of time, both physical and emotional pain is identified and eased, and users can confront and overcome their deepest longings and fears.
The OASIS may be fictional, but some of its seemingly therapeutic effects are factual, b...

Michelin Star Medicine: Food Start-Up Epicured Delivers Meals for GI & Chronic Condition Care
By JESSICA DaMASSA, WTF HEALTH
Food-as-Medicine startup, Epicured, looks and acts a lot like the consumer meal delivery startups booming during this pandemic (think Freshly, which was just acquired by Nestle for $1.5B) but with one important difference: all the meals are based on diets that have been clinically validated as treatments for chronic disease. The three year old company got its start in GI disorders, turning complex Low FODMAP diets, gluten-free diets, etc. into home-delivered, ready-to-eat dishes that patients with Crohn’s disease, Colitis, IBS, IBD, celiac, or other gastro conditions could actually i...

In this study, except for the reduction in body weight, the aging characteristics related to epidermal and muscle tissue in mice were significantly ameliorated in the CR group compared with the control group. Additional studies have indicated that not stem cells themselves but the stem cell microenvironment is the key factor mediating stem cell activation, proliferation and differentiation.
Mitochondrial dysfunction is an important factor leading to age-related muscular atrophy. Considering the dependence of skeletal muscle on ATP, loss of mitochondrial function, which can lead to a decrease in strength and enduranc...
