Broadening clinical evidence has markedly designated inositol(s) as a common and effective therapeutic approach for PCOS and infertility. Although considerable research has been focused on the use in clinical practice of myo-inositol (myo-ins) and D-chiro-inositol (D-chiro-ins), the two major inositol stereoisomers, less attention has been paid to their bioavailability. Therefore, the aim of this paper is to gather and analyze information on inositol(s) bioavailability, to better delineate its optimal concentration for scientific and clinical purposes...

BACKGROUND AND OBJECTIVES: Physicians must communicate effectively with patients. Actual patients (APs) rarely evaluate medical students' clinical skills; instead, standardized patients (SPs) provide proxy ratings. It is unclear how well SP ratings mirror AP experiences. The aim of this study was to compare AP and SP assessments of medical students' communication skills and professionalism. We hypothesized that their perspectives would be similar, but distinct, and offer insight about how to more reliably include the patient's voice in medical education...

Mitchell A Pavao-Zuckerman, Christine Sookhdeo
Urbanization affects ecosystem function and environmental quality through shifts in ecosystem fluxes that are brought on by features of the built environment. Green infrastructure (GI) has been suggested as a best management practice (BMP) to address urban hydrologic and ecological impacts of the built environment, but GI practice has only been studied from a limited set of climatic conditions and disciplinary approaches. Here, we evaluate GI features in a semiarid city from the perspective of soil ecology through the application of soil nematode community analysis...

Cover crops are important management practices for reducing nitrogen (N) leaching, especially in the Chesapeake Bay watershed, which is under total maximum daily load (TMDL) restraints. Winter cereals are common cool-season crops in the Bay watershed, but studies have not directly compared nitrate-N (NO-N) leaching losses from these species. A 3-yr cover crop lysimeter study was conducted in Beltsville, MD, to directly compare NO-N leaching from a commonly grown cultivar of barley ( L.), rye ( L.), and wheat ( L...

Francisco José Roma Paumgartten
Notwithstanding its approval by the National Committee for Ethics in Research (Conep) on April 19, 2016, a trial of the so-called "synthetic" phosphoethanolamine (syn-phospho) pill in cancer patients raises ethical concerns. An analysis by a laboratory contracted by the Ministry of Science, Technology and Innovation (MCTI) revealed that syn-phospho contained a great amount of impurities and did not meet standards of pharmaceutical quality required for an investigational drug. Cytotoxicity against human tumor cell lines and in vivo rodent xenograft tumor assays consistently failed to demonstrate a potential anticancer activity of syn-phospho...

This study addresses the practical, methodological and ethical challenges that were found in three studies that used focus groups with people with severe mental illness, in the context of community mental health services in Brazil. Focus groups are a powerful tool in health research that need to be better discussed in research with people with severe mental illness, in the context of community mental health facilities. This study is based on the authors' experience of conducting and analyzing focus groups in three different cities - Campinas, Rio de Janeiro and Salvador - between 2006-2010...

This paper examines the development of a treatment - a fixed-dose combination of artesunate and mefloquine - in Brazil, from three points of view: in terms of access to medication; to record and report successes; and to look at the lessons learned. This product development took place in the ambit of a public-private partnership. Semi-structured interviews were held with key actors involved in the different phases of the development, and documents were analyzed. Two important points of reference orienting the design of the study and analysis were: a logical model for access to medication; and evaluation of programs...

Chlordecone (Kepone) (CLD) is a highly persistent pesticide which was extensively used in the French West Indies; high levels of CLD can still currently be found in large agricultural areas. As CLD transfers from soil to animals mainly via involuntary ingestion, the consumption of foodstuffs derived from animals raised in contaminated areas may significantly contribute to exposure of humans to CLD. The present study was designed to test the efficacy of two different activated carbons (ACs) sources in limiting CLD transfer from soil to animal...
