Boston, Massachusetts - Measuring a menopausal woman’s pulse wave at her wrist may help explain the increase in cardiovascular disease risk during menopause better than a standard blood pressure measurement, according to preliminary research presented at the American Heart Association’s Basic Cardiovascular Sciences 2019 Scientific Sessions.

Washington, DC - A large-scale, collaborative, systems biology approach is needed to expedite the discovery of treatments for dry age-related macular degeneration (AMD) – a leading cause of blindness among people 65 and older for which is there is no treatment— according to a report by a working group of scientists appointed by the National Advisory Eye Council (NAEC). The NAEC is a 12-member panel that guides the National Eye Institute (NEI), part of the National Institutes of Health. The NAEC charged the working group to assess the state of research on dry AMD and to propose directions for future research.

Washington, DC - In a study of open-label Truvada as daily pre-exposure prophylaxis (PrEP) to prevent HIV among 427 young African women and adolescent girls, 95% initiated the HIV prevention strategy, and most used PrEP for the first three months. However, PrEP use fell among participants in this critical population during a year of follow-up clinic visits, although HIV incidence at 12 months was low. The preliminary results suggest that tailored, evidence-based adherence support strategies may be needed to durably engage young African women in consistent PrEP use.

Washington, DC - Hyperglycemia, or high levels of glucose, is common in patients with acute ischemic stroke and is associated with worse outcomes compared to normal blood sugar levels. Animal studies also pointed to an effect of high blood sugar in worsening stroke injury. Stroke experts have debated whether intensive glucose management after acute ischemic stroke leads to better outcomes but a new study in JAMA finds that aggressive methods are not better than standard approaches. The study was supported by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health.
Better science needed to support clinical predictors that link cardiac arrest, brain injury, and death

Dallas, Texas - According to new research in the American Heart Association’s journal Circulation, resuscitation and post-resuscitation care after cardiac arrest have both improved but mortality remains high. Most of the poor outcomes and deaths of cardiac arrest survivors have been attributed to widespread brain injury, but inaccurate neurologic prognostication, resulting in withdrawal of life-sustaining treatment and deaths, may significantly bias clinical studies, leading to failure in detecting the true study outcomes.
