Helicobacter pylori, a globally distributed gastric bacterium, is genetically highly adaptable. Microbiologists at Ludwig-Maximilians-Universitaet (LMU) in Munich have now characterized its population structure in individual patients, demonstrating an important role of antibiotics for its within-patient evolution.
Dengue, also known as dengue fever, is a viral disease transmitted to humans by mosquitoes of the genus Aedes. The incidence of dengue is currently increasing dramatically, and it is now one of the diseases said to be re-emerging. Researchers at the Institut Pasteur have conducted a study to determine the burden of dengue in Bangladesh and identify key risk factors for infection.
A study finds that exposure to fine particulate matter in the first years of life is associated with poorer performance in working memory and executive attention.
Computational modeling of social networks suggests that vaccination programs are more successful in containing disease when individuals have access to local information about disease prevalence. Anupama Sharma of The Institute of Mathematical Sciences in Chennai, India, and colleagues present these findings in PLOS Computational Biology.
New research from Brigham Young University professors finds there is a better way to help increase support for vaccinations: Expose people to the pain and suffering caused by vaccine-preventable diseases instead of trying to combat people with vaccine facts.
New findings from a study by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, show that US incidence rates for aggressive subtypes of uterine cancer rose rapidly among women ages 30 to 79 from 2000 to 2015. The findings also reveal racial disparities, including higher incidence of these aggressive subtypes and poorer survival -- irrespective of subtype and cancer stage -- among non-Hispanic black women than among women in other racial/ethnic groups.
Almost 3,600 people participated in a European study on the impact of green and blue spaces on mental health and vitality.
Researchers in the UK have developed a new method for evaluating plutonium workers' historical internal radiation exposure in a study funded by the National Institute for Health Research. They focused their efforts on workers employed at the start of plutonium operations at the Sellafield (formerly Windscale) nuclear reprocessing facility in the UK.
Cholesterol levels in US youth have improved from 1999 to 2016, but only half of children and adolescents are in the ideal range and 25% are in the clinically high range, according to a study published in JAMA, led by Amanda Marma Perak, M.D. M.S., cardiologist at Ann & Robert H. Lurie Children's Hospital of Chicago.
In Mexicali, Mexico, an uncontrolled epidemic of Rocky Mountain spotted fever, one of the deadliest tickborne diseases in the Americas, has affected more than 1,000 people since 2008. A binational team of researchers led by the University of California, Davis, has conducted the first comprehensive study to examine risk factors for the disease in Mexicali. Researchers examined dogs, ticks, and surveyed households in 200 neighborhoods.
