Importance: Patients often visit the emergency department (ED) near the end of life. Their common disposition is inpatient hospital admission, which can result in a delayed transition to hospice care and, ultimately, an inpatient hospital death that may be misaligned with their goals of care.

Objective: To assess the association of hospice use with a novel multidisciplinary hospice program to rapidly identify and enroll eligible patients presenting to the ED near end of life.

Purpose/objectives: The onset of the coronavirus disease 2019 pandemic increased the demand for inpatient services and led to widespread staffing shortages in the acute and post-acute setting, contributing to delayed inpatient throughput and leading to capacity crises. Novel strategies are needed to facilitate the efficient progression of hospitalized patients when medically ready for lower levels of care. The authors have developed a foundational strategic framework for patient progression to ensure capture of patient progression data, enhance efficiency, and optimal utilization of post-acute resources in increasingly complex and resource-constrained acute and post-acute environments.

The COVID-19 pandemic has highlighted that bereavement care is under-recognized with few hospitals offering universal bereavement services. One hundred sixty-nine bereaved individuals, whose loved ones died at our hospital during 2021 and 2022, completed a survey about their experience with the bereavement program. Of respondents who recalled receiving bereavement outreach, 79% rated speaking to a team member soon after the death as having a positive impact on their bereavement, and 75% rated receiving a condolence call or note from the team positively.

It is the second decade of controversy regarding the cardiovascular effects of cyclo-oxygenase-2 (COX-2) inhibitors. At this time, celecoxib is the only available COX-2-specific inhibitor for treatment of pain and inflammation. Therefore, the present study was designed primarily to determine the impact of celecoxib on cholesterol handling (uptake via scavenger receptors and efflux from the cells) and foam cell formation in human THP-1 macrophages, followed by comparison to rofecoxib and other non-steroidal anti-inflammatory drugs (NSAIDs).

"Truth" has been used as a baseline condition in several functional magnetic resonance imaging (fMRI) studies of deception. However, like deception, telling the truth is an inherently social construct, which requires consideration of another person's mental state, a phenomenon known as Theory of Mind. Using a novel ecological paradigm, we examined blood oxygenation level dependent (BOLD) responses during social and simple truth telling.

This study examines the role of resilience in the romantic lives of Black same gender loving romantic male couples in the nyc metropolitan area. Twenty in-depth interviews (N=40) were conducted, ranging in age from 18 to 67, and were predominately low income and moderately educated. Research questions were: 1) What strategies do Black sgl couples use to preserve and improve their relationships and (2) What are the potential problems or barriers your relationship experiences? The data from interviews were aggregated and three major themes emerged: direct communication strategies, relationship support, and intentional and thoughtful decision making.

This article is about a transdisciplinary project between the social, human and life sciences, and the felt experiences of the researchers involved. 'Transdisciplinary' and 'interdisciplinary' research-modes have been the subject of much attention lately--especially as they cross boundaries between the social/humanistic and natural sciences. However, there has been less attention, from within science and technology studies, to what it is actually like to participate in such a research-space.

Immunologic derangements in rheumatoid arthritis (RA) patients likely contribute to premature atherosclerotic cardiovascular disease (CVD). Traditional CVD risk factors do not reliably identify at-risk RA patients, probably because disease-associated mechanisms are not taken into account. The purpose of this study was to determine whether plasma from subjects with RA exhibits atheroma-promoting properties leading to disruption of cholesterol homeostasis in human monocytes/macrophages.

Atherosclerosis is considered to be a chronic inflammatory disease of the arterial wall. Atherogenesis is accompanied by local production and release of inflammatory mediators, for which the macrophage is a major source. The proinflammatory cytokine, interferon (IFN)-γ derived from T cells, is expressed at high levels in atherosclerotic lesions.

The adenosine A(2A) receptor (A(2A)R) plays an important role in the regulation of inflammatory and immune responses. Our previous work has demonstrated that A(2A)R agonists exhibit atheroprotective effects by increasing expression of reverse cholesterol transport proteins in cultured human macrophages. This study explores the impact of pharmacologic activation/inhibition and gene silencing of A(2A)R on cholesterol homeostasis in both THP-1 human monocytes/macrophages and primary human aortic endothelial cells (HAEC).

Surfactant miscible-displacement experiments represent a conventional means of estimating air-water interfacial area (A(I)) in unsaturated porous media. However, changes in surface tension during the experiment can potentially induce unsaturated flow, thereby altering interfacial areas and violating several fundamental method assumptions, including that of steady-state flow. In this work, the magnitude of surfactant-induced flow was quantified by monitoring moisture content and perturbations to effluent flow rate during miscible-displacement experiments conducted using a range of surfactant concentrations.
