A recent study from McMaster University has revealed that high-intensity interval training (HIIT) is more effective than traditional moderate exercise in enhancing aerobic fitness among stroke survivors. Stroke, which affects approximately 15 million people globally each year, often necessitates rehabilitation for survivors, including physical therapy. The study involved 82 participants who engaged in either HIIT or moderate exercise sessions over 12 weeks. Results indicated that those in the HIIT group saw their cardiorespiratory fitness levels improve twice as much as those in the moderate exercise group, with benefits persisting eight weeks post-study. Researchers highlighted the importance of integrating higher intensity exercise into rehabilitation programs to mitigate long-term stroke impacts and reduce recurrence risks. Experts have called for more extensive research to assess HIIT's applicability across a broader range of stroke survivors, particularly those with severe impairments. The study is published in the journal *Stroke*. 
Published: Aug 10 2024, 6 pmeznews.inA comprehensive review by the World Health Organization (WHO) has concluded that there is no evidence linking mobile phone use to an increased risk of brain cancer. This meta-analysis, which examined 63 studies from 22 countries conducted between 1994 and 2022, found no correlation between mobile phone usage, workplace radio frequency electromagnetic fields (RF-EMF), or cell towers and various types of brain and pituitary cancers, as well as leukemia in both adults and children. The findings challenge previous concerns, including the International Agency for Research on Cancer's classification of mobile phones as "possibly carcinogenic." While the review acknowledges the low-to-moderate certainty of its conclusions due to the observational nature of the studies, it emphasizes the need for ongoing research to monitor the health impacts of evolving technologies. Experts stress that current evidence does not support a significant association between RF-EMF exposure and brain cancer.
Published: Sep 09 2024, 9 pmeznews.inA recent review published in *Nutrients* highlights the significant role of dietary patterns in promoting healthy aging and extending healthspan, defined as the period free from chronic diseases. The study examined four diets—caloric restriction, intermittent fasting, the Mediterranean diet, and the ketogenic diet—finding that each may influence key metabolic pathways related to cellular repair and inflammation. Caloric restriction aids in weight management and reduces inflammation, while intermittent fasting enhances insulin sensitivity and cardiovascular health. The Mediterranean diet, rich in plant-based foods, supports cognitive function and gut health, and offers metabolic benefits akin to caloric restriction. Although the ketogenic diet may improve triglyceride levels, its long-term safety remains uncertain. Experts recommend combining these dietary strategies for optimal health benefits, emphasizing that individual preferences and health goals should guide dietary choices. Overall, a holistic approach, including diet, exercise, and social connections, is crucial for fostering healthy aging.
Published: Sep 09 2024, 10 pmeznews.inRecent studies have highlighted the significant link between type 2 diabetes and increased dementia risk, emphasizing the importance of maintaining a healthy lifestyle. Research published in August indicates that stable hemoglobin A1c (HbA1c) levels can predict a lower risk of Alzheimer’s disease and related dementias among older adults. A large study involving 374,021 veterans revealed that those with at least 60% of their HbA1c readings in the target range had a reduced dementia risk. Meanwhile, another study analyzed MRI scans of over 31,000 individuals, finding that diabetes could age the brain by approximately 2.3 years compared to chronological age. However, engaging in healthy behaviors, such as regular exercise and avoiding smoking, may mitigate this risk. Experts stress the need for lifestyle interventions to protect brain health, particularly for those living with diabetes, as the prevalence of the condition continues to rise globally.
Published: Sep 08 2024, 1 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.
