Breakthrough trial shows MRI-guided radiation can reduce prostate cancer treatment toxicity
Nearly 290,000 American men will be diagnosed with prostate cancer in 2023. Thankfully, the vast majority will be diagnosed with clinically localized disease and can be cured with either surgery or radiotherapy. Emerging clinical trial data have cemented stereotactic body radiotherapy (SBRT), a form of radiation in which ≤5 daily doses are delivered with high

Raman-Based Urine Sensor Detects Cancer Metabolites
Researchers at the Korea Institute of Materials Science (KIMS) creaetd a Raman-spectroscopy-based urine test that can detect metabolic compounds that are produced by pancreatic and prostate cancers, potentially allowing for rapid and convenient cancer screening. The technology consists of a paper strip onto which a urine sample can be added. The paper contains ‘coral-shaped’ structures that assist in amplifying the optical signal of cancer metabolites in the urine when the paper strip is illuminated with light, letting the researchers acquire spectral signals for each sample. By analyzing urine samples from cancer pati...

Fight Aging! Newsletter, February 13th 2023
This study investigated whether taller Polish adults live longer than their shorter counterparts. Data on declared height were available from 848,860 individuals who died in the years 2004-2008 in Poland. To allow for the cohort effect, the Z-values were generated. Separately for both sexes, Pearson's r coefficients of correlation were calculated. Subsequently, one way ANOVA was performed.
The correlation between adult height and longevity was negative and statistically significant in both men and women. After eliminating the effects of secular trends in height, the correlation was very weak (r = -0.0044 in men and ...

Aging as a Disease: a Zoo Contains Animals, But is Not Itself an Animal
The author of today's open access commentary is quite prolifically opinionated on the topic of mTOR and its status as a central pillar of programmed aging, particularly the hyperfunction version of programmed aging theories. Nonetheless, he sometimes has interesting things to say, as is the case here on the topic of whether aging is a disease. A great deal of ink has been spilled of late on the question of whether or not aging is a disease. This is the case not because everyone suddenly developed an interest in semantics, but rather because it directly affects the regulation of medical development, and thus the flow of fun...

Ultrasound is Ultra-Cool
This study is also a major step forward for the exciting possibility of combining focused ultrasound with targeted delivery of medications or antibodies that normally have limited capability to cross the blood brain barrier from the blood to the brain.”
Similarly, researchers at Yonsei University College of Medicine (South Korea) found that focused ultrasound improved the delivery of Alzheimer’s drugs by over eight times. “While there is no complete cure for dementia, we hope that open BBB [blood brain barrier] surgery using FUS surgery can help give hope to dementia patients,” the lead researcher said.

AI-Enhanced Prostate Cancer Treatment: Interview with Brittany Berry-Pusey, Co-Founder and COO at Avenda Health
Avenda Health, a medtech company based in Santa Monica, California has developed the FocalPoint ablation system, an AI-powered prostate cancer therapy. The system is designed to provide localized prostate cancer treatment and its AI system equips clinicians with a map of a patient’s cancer, along with treatment simulations to help them chose the best course of action.
The goal behind the system is to effectively treat the tumor, but preserve as much of the healthy tissue as possible, thereby maximizing patient chances at retaining full urinary and sexual function. The ablation technology itself is laser-b...

HDL Level, Age, and Smoking are the Largest Determinants of Mortality Risk in Old People
An interesting epidemiological study here stratifies the contributions of various metrics to mortality in later life, age 70 and older. The authors find that the largest effects arise from HDL level, chronological age, and smoking. The largest single cause of death in our species is atherosclerosis, a progressive malfunction in clearance of cholesterol from blood vessel walls that leads to fatty plaques, narrowed arteries, stroke, and heart attack. HDL particles carry excess cholesterol from blood vessel walls back to the liver for excretion, and - thus over a lifetime - the more HDL in circulation one has, the greater the...

5 Tips for Keeping Your Brain Healthy While Caregiving
Many of us cope with the stress of caring for someone who has dementia. We agonize over the increasing losses that our loved one faces as dementia works its way through their brains. We also worry about ourselves. Will we, too, end our lives without recognizing the people we love? What, if anything, can we do to protect our own brains? With this question in mind, I asked two brain experts for their input on how caregivers can practice self-care and reduce worry about their health—specifically their brain health.
What's good for the heart is good for the brain: First, I questioned Benjamin T. Mast, Ph....

Loving Yourself: A Caregiver ’s Ultimate Challenge
We've all heard that we must first learn to love ourselves before we can love others. Yet, many of us have grown up with family members who were hard on us or taught us that self-love is selfish or arrogant, which couldn’t be further from the truth.
What Is Self-Love? Louise Hay, a founder of the self-help movement and author of several New Thought motivational books, defines self-love as a deep, unconditional acceptance and appreciation for all parts of who we are. Self-love is the culmination of building awareness of ourselves, nurturing our minds and bodies, and acknowledging that we are good and valuabl...

Grandparent's Day: A Reminder of the Importance of the Older Generation
The importance of grandparents in the lives of children cannot be denied. Before our society became so mobile, it was common for children to grow up surrounded by extended family, including one or both sets of grandparents. Seniors often moved in with their adult children and young grandkids when they became frail.
My own childhood mirrored this now quaint picture of the past, and I’ve always felt happy about the fact that my children were involved with both sets of their grandparents as they grew up. Yet even though my kids enjoyed weekly grandparent visits, they were already in the minority. Many of their friends rare...
