New research from the George Washington School of Medicine suggests that cannabidiol (CBD) may offer protective benefits against UVA radiation, which can cause skin aging and cancer. In a small study involving 19 participants, those treated with a nano-CBD cream experienced reduced redness and skin thickening after exposure to high levels of UV radiation compared to a control cream without CBD. While 21% of participants showed less redness with the CBD treatment, experts caution that more extensive research is needed before CBD can be considered a viable alternative to sunscreen. The study highlights the potential of CBD as an adjunct to existing sun protection methods, but researchers emphasize it should not replace sunscreen. The findings, published in the *Journal of the American Academy of Dermatology*, open the door for future investigations into CBD's role in skin protection against UV damage. 
Published: Jul 23 2024, 11 pmeznews.inA recent study conducted by Japanese researchers has explored the cognitive benefits of matcha green tea in older adults, particularly those experiencing mild cognitive decline. While the study, published in *PLOS ONE*, found no significant improvements in broader cognitive functions like memory, participants consuming matcha reported enhancements in social cognition and sleep quality. The study involved 99 participants aged 60 to 85, who were monitored over 12 months, with those in the matcha group taking daily capsules containing high levels of catechins and theanine. Researchers noted that improved social acuity—specifically in recognizing facial expressions—could be linked to the anti-inflammatory properties of catechins. Experts emphasize the need for further research to understand matcha's effects more thoroughly, particularly regarding its potential role in improving sleep and mood, while cautioning against viewing it as a standalone intervention for dementia prevention.
Published: Sep 07 2024, 12 pmeznews.inA recent study has revealed that early-life exposure to low-density lipoprotein (LDL) cholesterol significantly increases the risk of developing atherosclerosis, a condition linked to cardiovascular disease. Researchers found that intermittent exposure to a high-fat Western-style diet in mice led to larger atherosclerotic plaques compared to continuous exposure later in life. This trend was echoed in a Finnish cohort study, which demonstrated that higher LDL cholesterol levels in youth correlated with a greater presence of arterial plaques in mid-adulthood. The findings, published in *Nature*, suggest that early cholesterol testing could be crucial for identifying individuals at risk of heart disease. Experts emphasize that the type of dietary fats consumed plays a critical role in cholesterol management, as diets high in saturated fats can reduce the liver's ability to clear LDL cholesterol from the bloodstream, thereby increasing the likelihood of arterial blockages.
Published: Sep 06 2024, 11 pmeznews.inA recent study from the University of South Wales has revealed that a new triple-combination pill, GMRx2, is more effective in managing hypertension than traditional single-drug therapies. The Phase 3 clinical trial involved around 300 Black African participants in Nigeria with uncontrolled high blood pressure. Those taking GMRx2, which contains low doses of telmisartan, amlodipine, and indapamide, experienced a significant reduction in systolic blood pressure, with 31 mmHg lower readings compared to 26 mmHg in the standard care group. The study found that 81% of GMRx2 participants achieved blood pressure control after one month, compared to 55% with standard treatment. Experts believe that this combination pill could alleviate the "pill burden" faced by many patients, potentially improving adherence to treatment. Following FDA submission, researchers aim to implement this innovative therapy widely, particularly in regions with high hypertension rates.
Published: Sep 06 2024, 9 pmeznews.inA recent study published in the *Canadian Journal of Cardiology* has revealed a potential link between cellphone use and an increased risk of cardiovascular disease. Analyzing data from nearly 450,000 participants, researchers found that those making calls for six or more hours weekly had a 21% higher risk of cardiovascular events compared to infrequent users. This correlation was particularly pronounced among smokers and individuals with diabetes. Factors such as psychological distress, sleep quality, and neuroticism were identified as significant contributors to this association. However, experts caution that the study's observational nature does not establish causation, and other lifestyle factors may also play a role. As cellphone usage continues to rise globally, the findings underscore the need for further research into the health implications of mobile technology, encouraging individuals to adopt healthier habits to mitigate cardiovascular risks.
Published: Sep 06 2024, 6 pmeznews.inNew research published in *Frontiers in Neuroscience* suggests a significant link between excessive nighttime light pollution and an increased risk of developing Alzheimer’s disease, particularly in individuals under 65. The study, led by Robin Voigt-Zuwala, Ph.D., utilized satellite data to assess light intensity across the U.S. from 2012 to 2018, correlating it with Medicare data on Alzheimer’s prevalence. Findings indicated that for those aged 65 and younger, light pollution was a stronger risk factor than any other studied, while for older individuals, factors like high blood pressure and diabetes had a greater correlation. Experts emphasize the need for further research to confirm these findings and explore the implications of both indoor and outdoor light exposure on sleep disruption, which may affect the brain's ability to clear Alzheimer’s-related proteins. The study aims to raise awareness about potential lifestyle changes, such as using blackout curtains, to mitigate risks associated with light pollution.
Published: Sep 06 2024, 10 ameznews.inA recent study published in *JAMA Network* suggests that lowering the threshold for potassium supplementation after cardiac surgery could benefit patients with atrial fibrillation (AFib) without increasing risks. Traditionally, potassium is administered intravenously when levels drop below 4.5 mEq/L; however, researchers found that a threshold of 3.6 mEq/L is equally effective in reducing AFib risk while saving an average of $111.89 per patient. AFib is the most common arrhythmia globally, affecting nearly one-third of the 1.5 million cardiac surgery patients each year. The study, which involved 1,690 patients across 23 surgical centers in the UK and Germany, concluded that the relaxed potassium standard does not lead to adverse outcomes. Experts emphasize the importance of maintaining potassium levels for cardiovascular health, noting that both low and high levels can pose serious risks.
Published: Sep 05 2024, 10 pmeznews.inRecent research has highlighted a concerning link between nighttime light exposure and an increased risk of developing type 2 diabetes. A study from Flinders University analyzed data from nearly 85,000 individuals in the U.K. Biobank, revealing that participants exposed to bright light between 12:30 AM and 6:00 AM were at a higher risk of diabetes, regardless of daytime light exposure. Published in _The Lancet Regional Health – Europe_, the findings suggest that reducing nighttime light exposure could serve as a simple and cost-effective measure to potentially delay or prevent diabetes onset. Experts emphasize the importance of good sleep hygiene and recommend turning off electronic devices at night as a preventive strategy. While the study underscores the significance of light in regulating circadian rhythms and metabolism, further research is necessary to fully understand the mechanisms at play and their broader health implications.
Published: Sep 04 2024, 10 pmeznews.inA recent study published in *Science Translational Medicine* has uncovered a potential link between high dietary salt intake and an increased risk of multiple sclerosis (MS), a chronic autoimmune disease affecting millions globally. Researchers identified a molecular pathway involving the SGK-1 and PRDM1-S genes that, when activated by elevated sodium levels, leads to dysfunction in regulatory T cells—immune cells that normally suppress harmful immune responses against the body. The study’s lead author, Dr. Tomokazu Sumida from Yale School of Medicine, emphasized the significance of understanding this pathway, suggesting it could inform new treatment strategies for autoimmune diseases. While the findings highlight the role of environmental factors like salt intake in MS, further research is essential to explore the broader implications for other autoimmune conditions and to validate these results in clinical settings. The study opens avenues for targeted therapies that could mitigate disease onset and progression.
Published: Sep 04 2024, 3 ameznews.inA recent study published in *JAMA Network Open* suggests that hormone therapy (HT) administered during perimenopause can slow biological aging in women, particularly benefiting those from lower socioeconomic backgrounds. Analyzing data from 117,763 postmenopausal women in the UK Biobank, researchers found that 40.3% had used HT, exhibiting fewer aging indicators compared to non-users. The most significant anti-aging effects were noted in women who began HT around age 48 for four to eight years. While HT can mitigate aging effects associated with lower socioeconomic status, it also carries risks of stroke, cancer, and dementia when started later in life. Experts highlight the importance of timing in HT administration, noting that benefits are most pronounced during perimenopause. The findings contribute to ongoing discussions about the safety and efficacy of HT, with a growing consensus that it may be advantageous when used appropriately.
Published: Sep 03 2024, 10 pmeznews.inA recent study has detected trace amounts of 16 heavy metals, including arsenic, lead, and cadmium, in 14 brands of tampons sold in the U.S. and U.K., raising concerns about the safety of menstrual products. Given that individuals who menstruate use an estimated 11,000 to 15,000 pads and tampons over their lifetimes, the potential for harmful chemical exposure is significant, particularly as tampons are inserted into sensitive areas of the body. The findings have sparked anxiety about the long-term health implications, especially regarding reproductive health. In a recent podcast episode, _Medical News Today_ editors discussed these findings with Dr. Anna Pollack, a public health expert whose research focuses on environmental chemical exposures and their effects on fertility and gynecologic health. The episode addresses how these metals may enter tampons and whether organic alternatives offer a safer option.
