Gonadal status modulates large elastic artery stiffness in healthy middle-aged and older men.

Hypogonadism is a risk factor for cardiovascular disease (CVD) in men related, in part, to increased oxidative stress. Elevated large artery stiffness and central pulsatile hemodynamics (e.g.

Patient Perspectives on Portal-Based Anxiety and Depression Screening in HIV Care: A Qualitative Study Using the Consolidated Framework for Implementation Research.

Electronic patient portals represent a promising means of integrating mental health assessments into HIV care where anxiety and depression are highly prevalent. Patient attitudes toward portal-based mental health screening within HIV clinics have not been well described. The aim of this formative qualitative study is to characterize the patient-perceived facilitators and barriers to portal-based anxiety and depression screening within HIV care in order to inform implementation strategies for mental health screening.

Perspectives of people living with HIV age 50 and over regarding barriers and resources for care.

With early and effective antiretroviral therapy leading to improved life expectancy in people with HIV (PWH), PWH aged 50 or older face concerns and issues related to aging. Providers at the University of Colorado identified a need to assess the healthcare needs of PWH aged 50 and older at the UCHealth Infectious Diseases/Travel (TEAM) Clinic in Aurora, Colorado. A survey was developed to illuminate participants' general rating of their health, factors that made it challenging to get the healthcare needed prior to COVID-19 and during COVID-19, and types of healthcare appointments and providers that would make a difference in healthcare experience.

Characterization of an archaeal inorganic pyrophosphatase from Sulfolobus islandicus using a [P]-NMR-based assay.

Inorganic pyrophosphatase catalyzes the conversion of pyrophosphate to phosphate and is often critical for driving reactions forward in cellular processes such as nucleic acid and protein synthesis. Commonly used methods for quantifying pyrophosphatase enzyme activity employ reacting liberated phosphate with a second molecule to produce absorbance changes or employing a second enzyme in coupled reactions to produce a product with a detectable absorbance. In this investigation, a novel [P]-NMR spectroscopy-based assay was used to quantitatively measure the formation of phosphate and evaluate the activity of inorganic pyrophosphatase from the thermoacidophilic Crenarchaeota Sulfolobus islandicus.

Management and outcomes of a COVID-19 outbreak in a nursing home with predominantly Black residents.

Background/objectives: Few studies present clinical management approaches and outcomes of coronavirus disease 2019 (COVID-19) outbreaks in skilled nursing facilities (SNFs). We describe outcomes of a clinical management pathway for a large COVID-19 outbreak in an urban SNF with predominantly racial minority (>90% black), medically complex, older residents.

Design: Single-center, retrospective, and observational cohort study (March 1, 2020-May 31, 2020).

Three-Tiered COVID-19 Cohorting Strategy and Implications for Memory-Care.

An outbreak of SARS-CoV-2 in a skilled nursing facility (SNF) can be devastating for residents and staff. Difficulty identifying asymptomatic and presymptomatic cases and lack of vaccination or treatment options make management challenging. We created, implemented, and now present a guide to rapidly deploy point-prevalence testing and 3-tiered cohorting in an SNF to mitigate an outbreak.

Development of a new and reliable assay for choline kinase using P NMR.

Choline kinase catalyzes the conversion of choline to phosphocholine (PC) by transferring a phosphate group from adenosine triphosphate (ATP) as the first step in the biosynthetic pathway for the membrane phospholipid phosphatidylcholine, an essential pathway in the parasitic protozoan. Commonly used methods for kinetically quantifying the enzyme include a radioisotope assay utilizing labeled choline and a coupled spectrophotometric assay with multiple enzymes and substrates that indirectly measures choline kinase activity. When testing potential inhibitors with the coupled assay, results can cast doubt on whether choline kinase is being inhibited or one of the coupled enzymes.

Does listening to music preoperatively reduce anxiety? An evidence-based practice process for novice researchers.

This article discusses the development of a clinical research question, the execution of a systematic literature search strategy, and the critical appraisal of a selected article. It demonstrates an evidence-based review process used by nurses to critique and evaluate the evidence used to support their work. This review was conducted by a novice researcher under the supervision of his lecturer.

OBSERVED DEFICIENCIES IN MEDICAL STUDENT KNOWLEDGE OF TRANSGENDER AND INTERSEX HEALTH.

Objective: Lesbian, gay, bisexual, transgender, and intersex (LGBTI) patients face many well-documented disparities in care which among transgender and intersex people can often be traced to providers' lack of knowledge.

Methods: We administered surveys to examine the self-assessed knowledge and attitudes of all medical students at Boston University regarding different LGBTI subpopulations. Survey questions were based on a Likert scale from 1 to 5; analysis was conducted with Wilcoxon rank sum tests.

Latent Tuberculosis Infection Testing Practices in Long-Term Care Facilities, Boston, Massachusetts.

Objectives: To describe latent tuberculosis infection (LTBI) testing practices in long-term care facilities (LTCFs).

Design: Retrospective cohort study.

Setting: Three Boston-area LTCFs.

Recurrent network of perceptrons with three state synapses achieves competitive classification on real inputs.

We describe an attractor network of binary perceptrons receiving inputs from a retinotopic visual feature layer. Each class is represented by a random subpopulation of the attractor layer, which is turned on in a supervised manner during learning of the feed forward connections. These are discrete three state synapses and are updated based on a simple field dependent Hebbian rule.
