Mental Health Treatment Among Nursing Home Residents With Alzheimer's Disease and Related Dementias.

Objectives: To examine the prevalence of mental health treatment among nursing home (NH) long-stay residents with Alzheimer's disease and related dementias (ADRD) and explore factors associated with utilization.

Design: Retrospective cohort study. Minimum Data Set data (April 2017-September 2018), Medicare Master Beneficiary Summary File, Part B Carrier file and Part D prescription file were used to identify mental illness and ADRD diagnoses, patient characteristics, and mental health treatment.

Increase in blood pressure precedes distress behavior in nursing home residents with dementia.

Background: Distress behaviors in dementia (DBD) likely increase sympathetic nervous system activity. The aim of this study was to examine the associations among DBD, blood pressure (BP), and intensity of antihypertensive treatment, in nursing home (NH) residents with dementia.

Methods: We identified long-stay Veterans Affairs NH residents with dementia in 2019-20 electronic health data.

Comparative studies on antitumor activities and apoptosis-inducing effects of enantiomeric ruthenium(II) complexes.

On the basis of our previous comparative studies on the DNA binding of a pair of ruthenium(II) complex enantiomers, -[Ru(bpy)PBIP] and -[Ru(bpy)PBIP] {bpy = 2,2'-bipyridine, PBIP = 2-(4-bromophenyl)imidazo[4,5-]1,10-phenanthroline}, in this study, their antitumor activities and mechanisms were further investigated comparatively. The cytotoxicity assay demonstrated that both the enantiomers exerted selective antiproliferative effects on cancer cell lines A2780 and PC3. Fluorescence localization experiments suggested that both the enantiomers effectively permeated the nucleus of HeLa cells and co-localized with DNA, resulting in their DNA damage and apoptosis.

Comparison of Claims-Based Frailty Indices in U.S. Veterans 65 and Older for Prediction of Long-Term Institutionalization and Mortality.

Background: Frailty is increasingly recognized as a useful measure of vulnerability in older adults. Multiple claims-based frailty indices (CFIs) can readily identify individuals with frailty, but whether 1 CFI improves prediction over another is unknown. We sought to assess the ability of 5 distinct CFIs to predict long-term institutionalization (LTI) and mortality in older Veterans.

The impact and cost-effectiveness of user fee exemption by contracting out essential health package services in Malawi.

Objectives: To examine the impact and cost-effectiveness of user fee exemption by contracting out essential health package services to Christian Health Association of Malawi (CHAM) facilities through service-level agreements (SLAs) to inform policy-making in Malawi.

Methods: The analysis was conducted from the government perspective. Financial and service utilisation data were collected for January 2015 through December 2016.

Comparative studies on DNA-binding and in vitro antitumor activity of enantiomeric ruthenium(II) complexes.

A pair of ruthenium(II) complex enantiomers, Δ- and Λ-[Ru(bpy)PBIP] {bpy=2,2'-bipyridine, PBIP=2-(4-bromophenyl)imidazo[4,5-f]1,10-phenanthroline} have been synthesized and characterized. The systematic comparative studies between two enantiomers on their DNA binding-behaviors with calf thymus DNA (CT DNA) were carried out by viscosity measurements, spectrophotometric methods and molecular simulation technology. Additional assays were performed to explore the cytotoxicity of the ruthenium(II) enantiomers against tumor cell lines.

Study on interaction between curcumin and pepsin by spectroscopic and docking methods.

The interaction between curcumin and pepsin was investigated by fluorescence, synchronous fluorescence, UV-vis absorption, circular dichroism (CD), and molecular docking. Under physiological pH value in stomach, the fluorescence of pepsin can be quenched effectively by curcumin via a combined quenching process. Binding constant (Ka) and binding site number (n) of curcumin to pepsin were obtained.
