Research reveals the human nose has a much more complex anatomy and function than previously believed, operating similar to two separate organs. A process called the nasal cycle alternately constricts and opens the nostrils. The nasal swelling rather than mucus is the primary cause of stuffiness. Decongestants provide temporary relief by causing nose-specific blood vessels to shrink. Understanding this process could provide more effective treatments for congestion and stuffy nose.
Scientists from the Karolinska Institutet in Sweden and the University of Glasgow have developed a novel DNA methylation (DNAm) clock, improving assessment of aging rate for patients with chronic kidney disease (CKD). The new biomarker allows for the measurement of biological vs chronological age. Further research is necessary to maximize the evaluation of lifestyle change effects on biological age using DNAm clocks.
When dealing with cold or flu symptoms, it’s important to choose over-the-counter medication wisely, as not all may work effectively. Notably, oral phenylephrine, an ingredient in many such medicines, doesn’t work and was removed from CVS Health’s offerings. Alternative effective medicines include Pseudoephedrine, nasal decongestant sprays – though they can worsen symptoms with prolonged use, nasal steroid sprays, and antihistamines. Also, neti pots could be helpful to relieve nasal congestion.
Colorectal cancer, the second-most deadly cancer globally, credited with over 1.7% of all deaths, is tackled predominantly with colonoscopies in the US. Recent randomized controlled trials have proved ambiguous, querying the cost-effectiveness and efficiency of the invasive procedure. This procedure operates on the adenoma-carcinoma hypothesis, removing polyps formed by mutant cells that could develop into cancer. Alternative screening procedures include the occult blood test and sigmoidoscopy, both less invasive and cheaper.
Poor sleep quality in overweight older adults is linked to health issues including anxiety, depression, and alteration in body composition, according to a Brazil-based study. The research, which assessed 95 participants, found poor sleepers had more body fat, less lean muscle, and poorer mental health. Consequently, sleep quality is emerging as a significant health factor, with obesity among older adults worldwide on the rise.
26 Oct 2023 — Researchers from the University of Minnesota and Brightseed are spotlighting more reasons to prioritize fiber in our regular diets. The study
Progressive strength training using resistance can counterbalance the harmful effects of a high-protein diet, according to a study conducted on mice. High-protein diets, while essential for muscle growth, may lead to increased risk of diabetes, heart disease and fat accumulation in sedentary lifestyles. The research suggests that regular resistance exercises might protect against high-protein diet-induced fat gain.
Companies are providing body scans for early-stage health issue detection amongst seemingly healthy patients, with costs ranging from $650. However, health professionals are concerned about unnecessary expenses and anxiety due to potential false positive results. Despite warnings from various health organizations, the demand for these scans, especially among the wealthy, continues to grow.
Scientists obsessed with aging are sketching a road map of how our bodies change as we grow old in the hopes that it will lead
Metastatic cancer is such a tough foe that even with powerful new targeted drugs, big advances in survival are far and few between. I’ve been
