OBJECTIVE: While decreased ocular blood flow is thought to be a possible contributor to glaucoma pathogenesis, it is unclear what role systemic phosphodiesterase inhibitors (PDEi) play. We performed a cross-sectional study of a nationally representative sample of the U.S. population to investigate the relationship between the most commonly used PDEi, sildenafil and theophylline, and self-reported glaucoma. METHODS: We used the National Health and Nutrition Examination Survey 2005-2008 cycles for this observational study...

Human milk contains essential micronutrients for growth and development during early life. Environmental pollutants, such as potentially toxic metals, can also be transferred to the infant through human milk. These elements have been well-studied, but changing diets and environments and advances in laboratory technology require re-examining these elements in a variety of settings. The aim of this study was to characterize the concentrations of essential and toxic metals in human milk from four diverse populations...

Reverse transcription quantitative polymerase chain reaction (RT-qPCR) is considered as the gold standard for accurate, sensitive, and fast measurement of gene expression. Prior to downstream statistical analysis, RT-qPCR fluorescence amplification curves are summarized into one single value, the quantification cycle (Cq). When RT-qPCR does not reach the limit of detection, the Cq is labeled as "undetermined". Current state of the art qPCR data analysis pipelines acknowledge the importance of normalization for removing non-biological sample to sample variation in the Cq values...

The predictable occurrence of whale sharks, Rhincodon typus, has been well documented in several areas. However, information relating to their migratory patterns, residency times and connectivity across broad spatial scales is limited. In the present study photo-identification data is used to describe whale shark population structure and connectivity among known aggregation sites within the Western Central Atlantic Ocean (WCA). From 1999 to 2015, 1,361 individuals were identified from four distinct areas: the Yucatan Peninsula, Mexico (n = 1,115); Honduras (n = 146); northern Gulf of Mexico, United States (n = 112), and Belize (n = 49)...

Contact lens-related eye infections, which can lead to serious outcomes, including blindness, are associated with several risk factors, including sleeping in lenses, exposing lenses to water, not adhering to replacement schedules, and reusing disinfecting solution (1). In some studies, adolescent and young adult contact lens wearers have been reported to be more likely than older adult contact lens wearers to develop eye infections (2,3) and more likely to have poor contact lens hygiene practices (2). In 2015, CDC reported the number and demographics of adult contact lens wearers in the United States to define the population at risk for contact lens-related eye infections (4); however, this estimate did not include adolescents...

Campylobacter and Salmonella are leading causes of bacterial gastroenteritis in the United States and are estimated to cause >1 million episodes of domestically acquired illness annually (1). Campylobacter and Salmonella are primarily transmitted through contaminated food, but animal-to-human and human-to-human transmission can also occur (2,3). Although occupationally acquired infections have been reported, occupational risk factors have rarely been studied. In 2015, the Occupational Safety and Health Administration (OSHA) identified 63 suspected or confirmed cases of Campylobacter infection over 3...

Hypertension is an important and common risk factor for heart disease and stroke, two of the leading causes of death in adults in the United States. Despite considerable improvement in increasing the awareness, treatment, and control of hypertension, undiagnosed and uncontrolled hypertension remain public health challenges (1). Data from the National Health and Nutrition Examination Survey (NHANES) were used to estimate the prevalence of hypertension, as well as awareness, treatment, and control of hypertension among adults aged ≥18 years in Los Angeles County compared with adults aged ≥18 years in the United States during 1999-2006 and 2007-2014...

Existing U.S. guidelines recommend that men with human immunodeficiency virus (HIV) infection should achieve virologic suppression* with effective antiretroviral therapy (ART) before attempting conception (1). Clinical studies have demonstrated that effective ART profoundly reduces the risk for HIV transmission (2-4). This information might be useful for counseling couples planning a pregnancy in which the man has HIV infection and the woman does not (i.e., a mixed HIV-status couple, often referred to as a serodiscordant couple)...

The growth of health care simulation in schools of medicine and nursing is noteworthy, as is the increasingly sophisticated simulation technology, support from funding agencies and foundations for research, well-attended annual conferences, and continued interest of accreditation and certification groups. Yet there are concerns preventing the full value of health care simulation to be realized when examined from a patient safety perspective. Basic questions are asked by funders of patient safety research when assessing past simulation projects undertaken to advance patient safety: Are the safety and quality of care to patients actually improved, and is something new being learned regarding the optimal use of simulation? Concerns focus on pursuing the right research questions to learn something new about the most effective use of simulation; doing more with simulation than simply providing an interesting, stand-alone educational experience; attending more seriously to how skill acquisition, maintenance, and progression get managed; and encouraging investigators, funders, and reviewers to expand their vision regarding what constitutes important inquiry and evidence in health care simulation...

Chronic pain is a common problem in the United States. Health care professions training at the undergraduate and graduate levels in managing chronic pain is insufficient. The Chronic Pain and Headache Management TeleECHO Clinic (ECHO Pain) is a telehealth approach at Project ECHO (Extension for Community Healthcare Outcomes), which supports clinicians interested in improving their knowledge and confidence in treating patients with chronic pain and safe opioid management. It is a vehicle for educating practicing clinicians (at the "spoke") based on work-place learning with cases selected by participants from their patient panels combined with short lectures by experts (at the "hub")...

Lentiviral vectors are increasingly the gene transfer tool of choice for gene or cell therapies, with multiple clinical investigations showing promise for this viral vector in terms of both safety and efficacy. The third-generation vector system is well characterized, effectively delivers genetic material and maintains long-term stable expression in target cells, delivers larger amounts of genetic material than other methods, is nonpathogenic, and does not cause an inflammatory response in the recipient. This report aims to help academic scientists and regulatory managers negotiate the governance framework to achieve successful translation of a lentiviral vector-based gene therapy...
