HOUSTON -- (Aug. 12, 2019) -- To combat the rise of drug-resistant bacteria, researchers are examining how one superbug adapts to fight an antibiotic of last resort, hoping to find clues that can prolong the drug's effectiveness.
Researchers at Rice University and the University of Texas Health Science Center at Houston ran experiments to track the biochemical changes that vancomycin-resistant Enterococci (VRE) underwent as they adapted to fight another antibiotic, daptomycin.

A new review to help physicians manage the risk of ovarian cancer in women who carry the BRCA1/2 gene mutations is published in CMAJ (Canadian Medical Association Journal).
New findings suggest that women with specific DNA characteristics in certain areas of the genome may live longer if they take aspirin before they are diagnosed with breast cancer. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings point to the need for studies on the potential of aspirin to prevent or treat breast cancer in some individuals.
Philadelphia, August 12, 2019 - Ninety-nine percent of cervical cancers are caused by human papillomavirus (HPV). More than 200 HPVs, some of which are associated with varying degrees of
CHICAGO -- Injuries have overtaken infectious disease as the leading cause of death for children worldwide, and psychologists have the research needed to help predict and prevent deadly childhood mishaps, according to a presentation at the annual convention of the American Psychological Association.
DALLAS - Aug. 9, 2019 - Changing the standard dose and timing of two therapies greatly cut tumor relapse and reduced side effects in mouse models of kinase mutated breast cancer and lung cancer, UT Southwestern Simmons Cancer Center researchers have found.
The study published today in Science Immunology suggests that giving the two therapies as short course, first-line treatment might work better than the current practice of providing one treatment early and the other treatment only if tumors relapse.
DALLAS - Aug. 9, 2019 - A new study from the UT Southwestern Simmons Comprehensive Cancer Center demonstrates that antiviral drugs for hepatitis C reduce liver-related deaths by nearly 50% in patients with a history of liver cancer.
The finding builds on a December 2018 study by the same researchers who found that antiviral drugs do not increase the risk of liver cancer recurrence, as was previously feared.
FINDINGS
A Veterans Health Administration program that added mental health specialists, care managers or both in primary care clinics significantly improved access to mental health and primary care services to veterans with behavioral health needs. In a clinic of 100 patients, each additional patient seen by such a mental health specialist or care manager was on average associated with 11% more mental health visits and 40% more primary care visits. The practice also resulted in 9% higher average annual costs for each patient.
BACKGROUND
CHICAGO -- Moderate exercise is not only good for memory as people age, it also appears to help prevent the development of physical signs of Alzheimer's, known as biomarkers, in those who are at risk for the disease, according to research presented at the annual convention of the American Psychological Association.
Bottom Line: An examination of a combined 28 years of data finds similarities in the characteristics and illnesses of patients requesting medical aid in dying in Oregon and Washington. The study included 3,368 prescriptions written for medical aid in dying, with 2,558 patients dying by lethal ingestion of medication, in the two states from 1998 to 2017 in Oregon and from 2009 to 2017 in Washington. Most of the patients were insured, non-Hispanic white individuals with some level of college education, 65 or older, and diagnosed with cancer.
Bottom Line: This observational study looked at whether extreme heat is associated with increased risk of hospitalization or death among the vulnerable population of patients with end-stage renal disease (ESRD). The study included 7,445 patients with ESRD who underwent long-term hemodialysis treatment at clinics in Boston, Philadelphia or New York from 2001 to 2012. During that time, 2,953 of the patients died.
A new study from the University of Bristol has linked bone strength to the timing of puberty.
Published today (Friday 9 August) in JAMA Network Open researchers looked at six repeated bone scans from 6389 children in Bristol's Children of the 90s study between the ages of ten and 25 to assess if the timing of puberty had any influence on bone density throughout adolescence and into early adulthood.
BOSTON -Increasingly, Alzheimer's disease (AD) research has focused on the preclinical stage, when people have biological evidence of AD but no or minimal symptoms, and when interventions might have the potential to prevent future decline of older adults. Researchers from Massachusetts General Hospital (MGH) have shed important new light on this area, reporting in a study published in JAMA Network Open that depression symptoms in cognitively healthy older individuals together with brain amyloid, a biological marker of AD, could trigger changes in memory and thinking over time.
A new study from The Westmead Institute for Medical Research (WIMR) has demonstrated how dual DNA barcoding could help improve the diagnosis of invasive fungal diseases, giving patients access to potentially life-saving treatment much sooner.
Ultrasound is a non-invasive and relatively inexpensive means of diagnosing a number of medical conditions. This review presents an analysis of the diagnostic value of ultrasound to draw comparison between different types of arthritic conditions. The 7 major arthritic conditions included in this study are osteoarthritis, rheumatoid arthritis, gouty arthritis, pseudogout (calcium pyrophosphate deposition disease), psoriatic arthritis, infectious arthritis and spondyloarthritis.
