Substantial COVID-19 research investment has been allocated to randomized clinical trials (RCTs) on hydroxychloroquine/chloroquine, which currently face recruitment challenges or early discontinuation. We aim to estimate the effects of hydroxychloroquine and chloroquine on survival in COVID-19 from all currently available RCT evidence, published and unpublished. We present a rapid meta-analysis of ongoing, completed, or discontinued RCTs on hydroxychloroquine or chloroquine treatment for any COVID-19 patients (protocol: https://osf.

Aim: We sought nurse managers' perspectives on challenges and opportunities with technology and how it may influence communication and leadership.

Background: e-Leadership is a conceptual framework used to understand and teach organisational leaders about the application of technology to leadership. Technology is integral to leadership, yet little is understood about how nurse managers may use this technology and how they negotiate the complexity of the multiple communication systems currently in use.

Background: College of nursing leaders can foster organizational learning as a means of achieving their desired organizational outcomes. Organizational learning has not previously been studied in colleges of nursing, leaving college administrators and faculty little guidance as they strive to improve outcomes in their own colleges.

Objectives: The purpose of this study was to discover new insights related to organizational learning in a college of nursing.

Background: We review research findings and the limitations of recent qualitative and quantitative studies of HIV prevalence and risk behaviors in military populations in three Caribbean countries (Dominican Republic, Belize, and Barbados).

Methods: This research shows how mental health issues, disordered substance use, and structuring aspects of the occupational field produce and reproduce patterns of risk behaviors.

Results: We discuss the use of formative research, the Positive Health, Dignity, and Prevention framework, and the use of implementation science (including research methods that employ alternative methodological assumptions to better elucidate both cultural nuances and unknown components of program impact in different military populations) as a means to tailor individual prevention strategies to military populations.

Background: Alirocumab, a monoclonal antibody to proprotein convertase subtilisin/kexin type 9 (PCSK9), lowers plasma low-density lipoprotein (LDL) cholesterol and apolipoprotein B100 (apoB). Although studies in mice and cells have identified increased hepatic LDL receptors as the basis for LDL lowering by PCSK9 inhibitors, there have been no human studies characterizing the effects of PCSK9 inhibitors on lipoprotein metabolism. In particular, it is not known whether inhibition of PCSK9 has any effects on very low-density lipoprotein or intermediate-density lipoprotein (IDL) metabolism.

Femtosecond laser-assisted cataract surgery is becoming more widely available as an option for patients considering cataract surgery. Controversies exist around determining the best platform for LCS, the potential global role and cost to the health care system of LCS, as well as the future of LCS in resident surgical training.

The frequency and intensity of extreme weather events have increased in recent decades; one example is Hurricane Sandy. If the frequency and severity continue or increase, adaptation and mitigation efforts are needed to protect vulnerable populations and improve daily life under changed weather conditions. This field report examines the devastation due to Hurricane Sandy experienced in Red Hook, Brooklyn, New York, a neighborhood consisting of geographically isolated low-lying commercial and residential units, with a concentration of low-income housing, and disproportionate rates of poverty and poor health outcomes largely experienced by Black and Latino residents.

Computerized physician order entry (CPOE) is a form of patient management health technology software used for providers to enter medical orders into a computer system. CPOE is a health care solution used to improve patient safety and quality of care, decrease costs, and reduce the risk of medical errors. However, there are unintended consequences to electronic health records that can actually cause an increase in medical errors.

Worldwide, military personnel have been recognized as a population at elevated risk for sexually transmitted infections and HIV. However, few evidence based behavioral interventions for the prevention of HIV and STIs have been rigorously evaluated in military personnel. We adapted the Popular Opinion Leaders (POL) intervention and piloted the adapted program with the Barbados Defence Force at one military base in Barbados.

Purpose: Sperm DNA damage is common amongst infertile men and may adversely impact natural reproduction, IUI-assisted reproduction and to a lesser degree IVF pregnancy. The objective of this study was to examine the influence of sperm DNA damage on embryo quality and/or development at IVF and ICSI.

Methods: We conducted a systematic review of studies that evaluated sperm DNA damage and embryo development and/or quality after IVF and/or ICSI.

The recent approval of azacitidine (Vidaza®), decitabine (Dacogen®) and vorinostat (Zolinza™) for myelodysplastic syndrome and cutaneous T-cell lymphoma has led to a wave of interest in epigenetic therapy. These DNA methylation inhibitors and the histone deacetylase inhibitor clearly have demonstrated activity in hematologic malignancies, but the future role of epigenetic therapy in solid tumors is still unknown. What is not commonly known is that azacitidine and decitabine were originally developed as cytotoxic nucleoside analogs and clinical trials were previously conducted in a variety of cancer types prior to the knowledge of their ability to inhibit DNA methylation.

To evaluate lead exposure among children living in border communities, the states of Arizona and New Mexico in the United States (US), and the states of Sonora and Chihuahua in Mexico collaboratively requested that the Centers for Disease Control and Prevention (CDC) provide technical assistance to document pediatric blood lead levels (BLLs) in children living along this part of the US/Mexico border. Two studies were conducted to evaluate BLLs of children aged 1-6 years. In 1998, 1210 children were tested in the Arizona/Sonora study; in 1999, 874 children were tested in New Mexico/Chihuahua.
