In phenylketonuria (PKU) patients, a genetic defect in the enzyme phenylalanine hydroxylase (PAH) leads to elevated systemic phenylalanine (Phe), which can result in severe neurological impairment. As a treatment for PKU, Escherichia coli Nissle (EcN) strain SYNB1618 was developed under Synlogic's Synthetic Bioticâ„¢ platform to degrade Phe from within the gastrointestinal (GI) tract. This clinical-stage engineered strain expresses the Phe-metabolizing enzyme phenylalanine ammonia lyase (PAL), catalyzing the deamination of Phe to the non-toxic product trans-cinnamate (TCA).

Introduction: Individuals who identify as lesbian, gay, bisexual, transgender, or queer (LGBTQ) face significant health disparities and barriers to accessing care. Patients have reported provider lack of knowledge as one of the key barriers to culturally responsive, clinically competent care. Many US and Canadian medical schools still offer few curricular hours dedicated to LGBTQ-related topics, and medical students continue to feel unprepared to care for LGBTQ patients.

Purpose Of Review: At a moment when UNAIDS (Joint United Nations Programme on HIV/AIDS) has acknowledged a 'prevention crisis,' and multiple countries and implementers are emphasizing 'user-centered' and/or differentiated models of delivering HIV treatment and prevention, it is essential to understand and act on best practices from all relevant interventions to create effective oral preexposure prophylaxis (PrEP) programs.

Recent Findings: It is possible to adapt private sector approaches to understanding and segmenting the preferences and mindsets of potential consumers to primary HIV prevention programs, as demonstrated by a voluntary medical male circumcision (VMMC)-focused intervention that successfully trained and supported counselors to identify and deliver tailored messages to men potentially undergoing VMMC. Literature on PrEP and demand creation is less extensive and suggests uneven application of user-centered design and demand-side thinking; a recent analysis of condom programing demonstrates that failure to maintain resources for social marketing can drive a collapse in use and an increase in HIV incidence.

Maryland's test for a finding of legal insanity (not criminally responsible [NCR]) allows a defendant to be found legally insane due to either a lack of appreciation of wrongfulness (cognitive impairment [CI]) or lack of ability to refrain from illegal behavior (volitional impairment [VI]). During a four-year period, 1,446 defendants underwent in-depth (post screening) evaluations for the NCR plea at Maryland state hospitals. Of the 416 defendants assessed as NCR by the hospitals' court-appointed evaluators, 44 (11%) were assessed as NCR due to VI alone.

As part of its mandate to evaluate and monitor program delivery, the Alberta Riparian Habitat Management Society (Cows and Fish) has commissioned independent evaluations to examine the effectiveness and applicability of the community-based riparian awareness and management program. The society's aim is to improve the understanding of landscape function, to better enable landowners and managers to make management decisions. The staff interaction evaluation examined staff ability to deliver certain valued characteristics, and identified whether the program and staff increased awareness and management action.

Two competitive particle concentration fluorescence immunoassays were developed to measure blood levels of analogs of anti-diabetic drugs being tested in diabetic mice. Ligands that contained the active pharmacophores were conjugated to PPD for immunization and to beta-phycoerythrin for use as a tracer in the immunoassays. Approximately 90% of 262 compounds assayed were detectable at less than 120 nM in plasma which was well below the estimated therapeutic level of 1 microM for lowering blood glucose.

Monoclonal antibodies (MoAbs) were made to a known insulin sensitivity enhancer (ISE) compound, CS-045. The MoAbs were characterized with respect to binding other known thiazolidinedione ISE compounds using a CS-045 labeled with b-phycoerythrin in a competitive particle concentration fluorescence immunoassay (PCFIA). By comparing the rank order of IC50 values for each compound to its respective potency as an ISE, one MoAb (13E3) was selected for further characterization.

The purpose of this study was to examine the effects of aspirin use on mortality and morbidity rates in a subset of the control group of the Program on the Surgical Control of the Hyperlipidemias (POSCH) that was stratified by cigarette smoking status at the time of randomization. The clinical impact of aspirin intake in cigarette smokers and former cigarette smokers has not been well studied. POSCH was a randomized, controlled, clinical trial designed to ascertain the effects of lipid modification by the partial ileal bypass operation on clinical end-points and arteriographic changes in postmyocardial infarction subjects with hypercholesterolemia.

The Program on the Surgical Control of the Hyperlipidemias (POSCH) was a secondary atherosclerosis intervention trial employing partial ileal bypass surgery as the intervention modality. For this report, we analyzed 105 subgroups in 35 variables in POSCH, chosen predominantly for their potential relationship to the risk of atherosclerotic coronary heart disease (ACHD). We defined potential differential effects as those with: (1) an absolute z-value > or = 2.

The Program on the Surgical Control of the Hyperlipidemias (POSCH) was a randomized controlled clinical trial designed to ascertain whether cholesterol lowering induced by the partial ileal bypass operation would favorably affect overall mortality and the mortality and morbidity due to coronary heart disease. The trial results provided strong clinical and coronary arteriographic support for the beneficial effects of lipid modification for the reduction of atherosclerosis progression. At the same time, the surgery-assigned group experienced diarrhea and an increased incidence of kidney stones and gallstones compared to the control-assigned group.

Background: Serum creatinine has been reported in previous studies to be a prognostic indicator for overall mortality, in particular in a hypertensive population.

Methods: The Program on the Surgical Control of the Hyperlipidemias (POSCH) was a randomized, controlled clinical trial. All patients had survived a single myocardial infarction, were normotensive, were not obese, were not having heart failure, and were free of diabetes mellitus and renal disease at entry into the study.

Objective: Assessment of the relationship between changes in sequential coronary arteriograms and subsequent clinical coronary events.

Design: The Program on the Surgical Control of the Hyperlipidemias, a randomized secondary atherosclerosis intervention trial, obtained coronary arteriograms at baseline, 3, 5, and 7 or 10 years of follow-up. Assessments of changes between pairs of coronary arteriograms were made by two-member panels blinded to the patients' assigned treatment and to the temporal sequence of the films.
