Inoculating Against the Blues

A Vaccine for Depression - Nautilus delves into the pioneering research on developing a vaccine-like treatment for depression. This innovative approach focuses on targeting the immune system, which plays a crucial role in mental health. Researchers have discovered that certain immune responses can exacerbate depressive symptoms. By modulating these responses, it's possible to alleviate depression. This groundbreaking work opens up a new frontier in mental health treatment, moving beyond traditional methods and offering hope for more effective and lasting solutions for those battling depression.

A Grape Pain

A recent study has identified quercetin, a compound in red wine, as a potential cause of the notorious red wine headaches. This discovery challenges previous beliefs that tannins, sulfites, or histamines were to blame. Quercetin, found in grape skins, is beneficial as a grape sunscreen and a human antioxidant, but when combined with alcohol, it can disrupt the body's process of breaking down alcohol, leading to headaches. The study, co-authored by Andrew Waterhouse and Morris Levin, reveals that quercetin blocks an enzyme crucial for converting acetaldehyde into acetate, causing a buildup of toxins and resulting in headaches. Interestingly, cheaper wines tend to have less quercetin due to less exposure to the sun on grapes, potentially offering a workaround for those prone to these headaches. However, there's no definitive cure yet, and further research will explore this phenomenon more deeply. Why red wine gives you headaches, according to science - The Washington Post (gift article).

The Double-Edged CAR-T Sword

The FDA has raised concerns that CAR-T, a groundbreaking cancer treatment, might paradoxically cause new cancers in some patients. Approved in November 2017 for severe blood cancers, CAR-T therapy involves genetically modifying a patient's T cells to attack cancer cells. Despite its life-saving potential, the FDA reported 19 cases of new blood cancers post-treatment. While the risk is considered small and the benefits significant, this development has sparked a debate in the medical community. The FDA is investigating these cases to determine if there's a direct causal link between the treatment and the emergence of new cancers amidst CAR-T's remarkable success in saving thousands of lives.

Gut Glia

In the Gut's 'Second Brain,' Key Agents of Health Emerge delves into the fascinating world of glial cells in the enteric nervous system, often overshadowed by neurons. These cells play a crucial role in digestion and disease, a fact that scientists are just beginning to unravel. The gut, equipped with its complex network of nerve cells, functions almost independently from the brain and is responsible for digestion, from breaking down food to nutrient absorption and waste elimination. Recent studies have highlighted enteric glia's diverse and active role in this process, including their involvement in nutrient absorption, blood flow, immune responses, and even gut motility. This newfound understanding of glial cells in the gut could pave the way for novel treatments for gastrointestinal disorders and enhance our comprehension of the digestive system's intricate workings.

Hypnotic Gut Healing

In a surprising turn of medical treatment, hypnotherapy emerges as a potential relief for gut disorders. A story in the Atlantic centers around Zack Rogers, who, on his 12th birthday, began experiencing severe stomach pain, leading to a drastic weight loss and a prolonged struggle with his health. After years of ineffective medical treatments and facing the prospect of major surgery, Zack's mother sought a second opinion, which led to hypnotherapy. This unconventional approach gradually brought significant improvements, involving deep focus and relaxation to alter thought patterns. Zack's recovery was so profound that he regained his everyday life, including playing sports and attending college, a future that seemed impossible before the hypnotherapy. This case highlights hypnotherapy's unexpected yet impactful role in treating severe gut disorders. Hypnosis Could Work Wonders on IBS - The Atlantic.

Defining Death

What is death? | MIT Technology Review delves into the evolving understanding of death in neuroscience. It challenges traditional perceptions of death, suggesting it should be viewed as a transient process rather than an irreversible event. This shift in perspective emerged with medical advancements like CPR and mechanical ventilators, which blurred the lines between life and death. The concept of brain death, arising from observations of patients with severe brain damage, further complicated the definition of death. This has sparked medical, ethical, and legal debates. The article highlights that despite these advancements, the scientific understanding of the dying brain remains complex and filled with unanswered questions.

Brainwaves Beyond the Grave: The Science of Near-Death Experiences

Recent research published in "Resuscitation" delves into the enigmatic realm of near-death experiences. The study found that despite having flatlined brain activity, some cardiac arrest patients exhibited a surge of brain activity during CPR. Intriguingly, a subset of these patients could recall this experience post-recovery. One individual even remembered an audio test administered during their resuscitation. Researchers hypothesize this phenomenon might represent the brain's transition between life and death. This study sheds new light on the intricate relationship between consciousness and the dying brain.

Rethinking the Dirt on Immunity

The belief that letting kids play in the dirt boosts their immunity might need a revisit. The hygiene hypothesis suggested that early exposure to germs can strengthen young immune systems, potentially reducing allergies later in life. However, a recent study involving "wildling" mice (lab mice raised in natural environments) found that despite their exposure to many microbes, they weren't any less prone to allergies than their lab-raised counterparts. While the findings don't wholly debunk the hygiene hypothesis, they hint that the relationship between dirt and immunity is more complex than previously thought. So, while playing in the soil has its joys, its health benefits might be overstated. Swedish Scientists Put the Hygiene Hypothesis to the Test in Mice. Results Suggest Early Exposure to Dirt and Microbes Alone May Not Protect Against Asthma and Allergies.

Guided by Dough

The article Food Industry Influence Could Cloud the U.S. Dietary Guidelines, a New Report Says - The New York Times (gift article) reveals potential conflicts of interest. A report by the nonprofit U.S. Right to Know highlights that 9 out of 20 2025 Dietary Guidelines Advisory Committee experts have affiliations with the food, beverage, pharmaceutical, or weight loss industries. Such ties raise concerns about the objectivity of the guidelines, which are intended to be science-based recommendations for public health. While the current committee has fewer industry connections than previous ones, any potential bias underscores the importance of transparency and rigorous scientific review in public health recommendations. Despite the conflicts, the members feel they could remain objective.

008 - U.S. Food Czar, 9-Volt Nirvana, Dragons and Thymi - HealthHippie Week In Review - September 4, 2022

White House Conference on Hunger, Nutrition, and Health

The most exciting news story of the week came from NPR, How the White House nutrition conference may tackle Americans' unhealthy diets. The article discusses the recommendations of the report, Informing the White House Conference, to be discussed on September 28. Re-calibrating America's relationship with food is the first (and arguably the most important) step to digging ourselves out of our current exorbitantly priced, low-value healthcare model (value=quality/cost). I'm hoping a "Food Czar" for the USA is named as an end-product of the meeting.

Thinking about Thinking

Rather than continuously constructing images based on all your sensory input, your brain likely conserves energy by predicting what it should see based on your previous experience and context, keying in on aspects that do not conform. The article, Your Brain Is an Energy-Efficient 'Prediction Machine', discusses efforts to understand the predictive processing framework.

9-Volt Nirvana

Two items on transcranial electrical stimulation hit my awareness in one of those "messages from the universe" (or maybe it's just the algorithms doing their thing). I'm fellowship trained in neuro-electrophysiology but was unaware of the studies focused on using mild electrical stimulation to enhance brain function (my fellowship focused on monitoring, not therapeutics). Early in the week, I read the article Brain stimulation boosts memory for at least a month. Then, without searching, a previous episode of Radiolab, 9-Volt Nirvana, , was in my podcast queue. After reading and listening to the podcast, I wondered if this technology might improve my quest to learn to play the guitar. I found an article I plan to read: Differential Effects of Transcranial Direct Current Stimulation-tDCS-Depending on Previous Musical Training. The jury is still out on the efficacy and safety of transcranial stimulation. Although there are already commercially available devices, I will wait to see how the field develops before I try it out.
