Pesticide Exposure May Relate to Colorectal Cancer in Younger Adults
Researchers at the Vall d’Hebron Institute of Oncology identified epigenetic signatures linking diet, smoking and the herbicide picloram to early‑onset colorectal cancer. By analyzing DNA methylation patterns, they created exposure risk scores that correlated higher picloram use in U.S. counties with elevated cancer rates among adults under 50. The study confirms known lifestyle risks while highlighting a novel pesticide association, though causation remains unproven. Findings suggest the exposome—cumulative lifetime exposures—may help explain the alarming rise in colorectal cancer among younger populations.
Frequent or Longer Naps in Older Age May Signal Declining Health, Study Suggests
A long‑term JAMA Network Open study of 1,338 older adults found that longer and more frequent daytime naps, especially in the morning, are linked to higher mortality. Each additional hour of napping raised death risk by 13%, and each extra...
Keto May Work Best for Sending Diabetes Into Remission: Here's Why
A recent 12‑week study published in the Journal of the Endocrine Society compared a ketogenic (high‑fat, low‑carb) diet with a low‑fat diet in 51 adults aged 55‑62 with type 2 diabetes. Both groups lost weight, but the keto group exhibited a...
Could Anemia Increase the Risk of Developing Dementia?
A Swedish cohort of 2,282 adults aged 60+ was followed for up to 16 years to examine anemia’s link to dementia. Researchers found that baseline anemia raised the risk of developing dementia by 66 % compared with normal hemoglobin levels. The...
Anti-Amyloid Drugs May Not Work Against Alzheimer's but if so, What Will?
A Cochrane systematic review of 17 clinical trials involving over 20,000 patients with early Alzheimer’s found that anti‑amyloid drugs produce little to no clinically meaningful improvement in cognition or daily function. The analysis also highlighted an increased risk of brain...
Natural GLP-1 Discovery Hidden in Joints Could Revolutionize Arthritis Treatment
A study published in The Lancet Rheumatology found trace amounts of the body’s natural GLP‑1 hormone in the synovial fluid of patients with rheumatoid arthritis and spondyloarthritis. Researchers compared joint‑fluid and blood samples from the INART biobank and observed a...
Urine Biomarker May Predict Bladder Cancer Treatment Response, Study Finds
Stanford researchers have created a urine‑based liquid biopsy that detects tumor DNA to predict which non‑muscle invasive bladder cancer (NMIBC) patients will benefit from BCG immunotherapy. In a Cell‑published study, patients with detectable tumor DNA after BCG had a high...
What a Dietitian Would Eat in a Day to Help with ADHD
A preventive cardiology dietitian recommends a plant‑forward, Mediterranean‑style diet to help adults with ADHD manage focus, anxiety, and energy levels. She emphasizes stable blood‑sugar through balanced carbs, protein, fiber, and healthy fats, while warning against ultra‑processed foods and low‑carb keto...
Blood Test May Be More Effective and Cost-Efficient than Standard Cholesterol Tests
A recent JAMA study led by Northwestern researchers finds that measuring apolipoprotein B (apoB) offers a more accurate assessment of cardiovascular risk than traditional LDL or non‑HDL cholesterol tests. Using a simulation of 250,000 adults eligible for cholesterol‑lowering therapy, the apoB‑guided...
Too Busy or Tired to Exercise? Here's How to Stay on Track
Exercise is essential for health, yet busy schedules and fatigue often derail routines. The World Health Organization advises at least 150 minutes of moderate activity weekly, but aligning workouts with an individual’s chronotype—whether a morning or evening person—can boost cardiometabolic...
Brain Health: Staying More Active During the Day Helps Retain Brain Volume
A new Johns Hopkins study using wrist accelerometers and MRI scans found that older adults with less fragmented daily rest‑activity rhythms retain larger volumes in the hippocampus, parahippocampus and amygdala, while highly fragmented rhythms accelerate brain atrophy and ventricular expansion....
GLP-1s Don't Work for Everyone: Why, and What to Do?
GLP‑1 receptor agonists have become a cornerstone of modern weight‑loss therapy, yet roughly 20% of patients fail to achieve meaningful reductions. A recent review proposes pairing a GLP‑1 drug with the naltrexone‑bupropion combo (Contrave) to address this gap, leveraging complementary...
Single Blood Sample Could Soon Screen for Several Cancers, Study Suggests
UCLA researchers unveiled MethylScan, a low‑cost blood test that reads DNA methylation patterns in cell‑free DNA to flag multiple cancers and liver diseases from a single draw. By stripping out 80‑90% of background DNA, the assay slashes sequencing needs, driving...
AI Tool Analyzes CT Scans to Help Boost Early Lung Cancer Detection
A team at Kaunas University of Technology has created a dual‑scale AI system that simultaneously evaluates detailed and contextual information in CT scans, mimicking radiologists’ workflow. Trained on scans from healthy and cancer patients, the model distinguishes normal tissue, benign...
Flu Vaccine May Slash Alzheimer's Risk: Here's What Dose to Get
A new Neurology study of about 200,000 U.S. adults 65 and older found that receiving a high‑dose influenza vaccine cut Alzheimer’s disease risk by roughly 55 percent, compared with a 40 percent reduction for the standard‑dose shot. The analysis adjusted for health‑care...
