However, lower doses of losartan were associated with increased mortality risk, while high doses showed no increased risk compared to candesartan.
A systematic review of 17 studies found that low-energy-density diets improve weight loss and maintenance in adults. In children and adolescents, moderately strong evidence shows a relationship between higher energy density diets and increased weight. Lowering energy density is associated with enhanced satiety and reduced calorie intake.

Studies suggest stringent occupational and environmental standards are necessary to reduce the health burden of carcinogenic diesel exhaust.
A large prospective study indicates that chronic air pollution may accelerate cognitive decline in older adults, particularly in women. Higher levels of particulate matter exposure were associated with significantly faster cognitive decline over a four-year period.
A recent study published by Archives of General Psychiatry found a strong association between smoking and more rapid cognitive decline in men. The study analyzed data from over 5,000 men and women in the Whitehall II cohort study, revealing that continued smoking was linked to greater cognitive decline.
A large-scale analysis of over 250,000 people found that middle-aged adults with high blood pressure and other CVD risk factors have a substantially greater chance of having a heart attack or stroke during their remaining lifetime. The study also showed that traditional risk factors predict long-term development of CVD more than age.
Elderly patients who visit emergency departments are three times more likely to develop respiratory or gastrointestinal infections after returning to a long-term care facility. Isolating residents for 7 days following an ED visit can help prevent outbreaks and reduce the financial burden on healthcare facilities.
Researchers at McMaster University found that nearly 1 in 3 patients with pacemakers and no history of atrial fibrillation experience asymptomatic atrial arrhythmias, increasing stroke risk. These episodes were often undetected until they were picked up by the pacemaker, highlighting the importance of monitoring for silent fibrillation.
A new UC Davis study found that greater access to key attributes of high-quality primary care, including comprehensiveness and patient-centeredness, is associated with lower mortality. The study suggests that providing all Americans with a 'medical home' offering these attributes could yield major public health benefits.
A new study from the Norwegian Institute of Public Health found that children delivered by cesarean section have an increased risk of developing asthma by age three. This increased risk was particularly seen among children without a hereditary tendency to asthma and allergies.
Researchers analyzed data from a large study to find that certain protein markers in the blood, such as cystatin C and beta trace protein, are better predictors of an individual's prognosis than creatinine. These markers may indicate not only kidney health but also other aspects of well-being.
A new analysis by Michigan Technological University researchers suggests that solar photovoltaic systems can make electricity cheaper than what consumers pay their utilities. The study reveals that previous assumptions about the cost of solar energy were overly conservative, and that the true cost of photovoltaic technology is lower th...
A UK-wide cohort study found a significant increase in tuberculosis (TB) diagnoses among postpartum women, with a higher risk of TB in the six months following pregnancy. The study suggests that targeted screening of pregnant and post-partum women in high-risk groups may be necessary to prevent poorer outcomes.
An independent panel recommends closely monitoring men with localized, low-risk prostate cancer to delay treatment until disease progression. However, standardizing definitions and conducting additional studies are needed to clarify management strategies and optimize patient outcomes.
Recent solar panel cost reductions have led to a significant decrease in system costs, making solar energy comparable to traditional energy sources. The study estimates the true cost of solar panels at under $1 per watt, with system and installation costs varying widely.
A new study by the American Sociological Association found that health disparities among young US adults have grown substantially since 1980. The study suggests that as younger generations grow older and replace previous cohorts, the gap between healthy and unhealthy individuals will continue to widen.
Research reveals a growing health disparity among US young adults born since 1980, peaking at middle age before declining in old age. The study attributes the widening gap to factors like income inequality, obesity crisis, and digital divide, which are expected to worsen as younger generations replace older cohorts.
