To eliminate tuberculosis (TB) in the United States, current guidelines should be changed to reclassify all foreign-born residents from high incidence countries as “high-risk” regardless of the amount of time they have lived in the US.
Researchers reported that all five standard hospital-based performance measures used to gauge quality-of-care for hospitalized heart-failure patients may not be the best benchmarks since none were significant predictors of patient mortality during the critical first 60 to 90 days immediately following hospital discharge.
In work with mice, researchers at the University of California, San Diego, School of Medicine discovered a factor that could be responsible for many unexplained cases of elevated triglyceride levels.
Drugs known as beta blockers help reduce the heart’s workload during heart failure via their action on beta-adrenergic receptors in cardiac cells. However, doctors remain puzzled by the variable responses to beta blockers among patients. Researchers now show that the key to this variation lies in a single amino acid change in the beta1-adrenergic receptor, that may differ from person to person, which alters the receptor’s conformation and the receptor’s response to certain beta blockers.
A new report urges parents and children’s doctors to change their thinking about homesickness among children, to see it as a nearly universal, but highly preventable and treatable phenomenon — rather than an unavoidable part of childhood.
Young adults (ages 20 to 44) with normal lung function who later develop chronic cough and phlegm have a fourfold higher risk of developing chronic obstructive pulmonary disease.
During periods of fasting, brain cells responsible for stimulating the appetite make sure that you stay hungry. Now, a new study of mice reported in the January issue of the journal Cell Metabolism, published by Cell Press, reveals the complex series of molecular events that keep those neurons active.
Researchers at the Harvard School of Public Health (HSPH), Beth Israel Deaconess Medical Center and Dutch research institute TNO Quality of Life and Wageningen University, the Netherlands, found that, among hypertensive men, moderate alcohol consumption was associated with a decreased risk of fatal and non-fatal heart attack.
Using brain imaging, researchers from Washington University in St. Louis have identified several brain regions that are involved in the uniquely human ability to envision future events. The study, to be published in the journal PNAS, provides evidence that memory and future thought are highly interrelated and helps explain why future thought may be impossible without memories. Findings suggest that envisioning the future may be a critical prerequisite for many higher-level planning processes.
Children and adolescents who are obese or overweight have higher health care utilization and a significantly higher average of health care charges than their healthy-weight peers, according to a report in the January issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.
