Preconception care (PCC), defined as a set of interventions to help women optimize their health and well-being prior to pregnancy, can improve pregnancy outcomes and is recommended by national organizations including the Centers for Disease Control and Prevention and the American College of Obstetricians and Gynecologists. Women Veterans who use the Department of Veterans Affairs (VA) health care system may face elevated risks of adverse pregnancy and birth outcomes due to a high prevalence of chronic medical and mental health conditions as well as psychosocial stressors including sexual trauma history and intimate partner violence. Many women Veterans of childbearing age experience poverty and homelessness, which are key social determinants of poor reproductive health outcomes. Read More

The development of hematopoietic stem cell transplantation (HSCT) programs can face significant challenges in most developing countries because such endeavors must compete with other government health care priorities, including the delivery of basic services. While this is may be a limiting factor, these countries should prioritize development of the needed expertise to offer state of the art treatments including transplantation, by providing financial, technological, legal, ethical and other needed support. This would prove beneficial in providing successful programs customized to the needs of their population, and potentially provide long-term cost-savings by circumventing the need for their citizens to seek care abroad.

Background: Whether gastroesophageal reflux (GER) or GER disease (GERD) causes chronic cough in children is controversial. Using the PICO format, we undertook 4 systematic reviews. For children with chronic cough (>4-weeks duration) and without underlying lung disease: (1) who do not have gastrointestinal GER symptoms, should empirical treatment for GERD be used? (2) with gastrointestinal GER symptoms, does treatment for GERD resolve the cough? (3) with or without gastrointestinal GER symptoms, what GER-based therapies should be used and for how long? (4) if GERD is suspected as the cause, what investigations and diagnostic criteria best determine GERD as the cause of the cough?

Methods: We used the CHEST Expert Cough Panel's protocol and American College of Chest Physicians (CHEST) methodological guidelines and GRADE framework. Read More

Doxorubicin, an agent used to treat a variety of cancers, is cardiotoxic by triggering cardiomyocyte apoptosis. We previously showed that treating cultured cardiomyocytes with human high density lipoprotein in vitro or transgenic overexpression of human apolipoprotein A1, its main structural protein protects against doxorubicin induced cardiomyocyte apoptosis in a manner dependent on the scavenger receptor class B type I [Durham (2018) 314: H31-H44]. This was due to high density lipoprotein induced activation of Akt signaling in cardiomyocytes. Read More

Despite the advances in the management of thalassaemia major, heart disease remains the leading cause of mortality in patients afflicted with this disorder. Cardiac involvement in thalassaemia encompasses a spectrum of disorders including myocardial dysfunction, arrhythmias, pulmonary hypertension and peripheral vascular disease. Although cardiac siderosis (accumulation of iron in cardiac myocytes) as a consequence of repeated blood transfusions is deemed to be the main aetiologic factor for myocardial dysfunction in transfusion dependent patients, the significance of other pathophysiologic mechanisms is being increasingly recognized especially in non-transfusion dependent patients.

In arguing that articulate language is underpinned by an algorithmically simple neural operation, the Minimalist Program (MP) retrodicts that language emerged in a short-term event. Because spoken language leaves no physical traces, its ancient use must be inferred from archeological proxies. These strongly suggest that modern symbolic human behavior patterns - and, by extension, cognition - emerged both abruptly and late in time (subsequent to the appearance of as an anatomical entity some 200 thousand years kyr ago).
