Background: Frailty is a geriatric syndrome of significant public health concern that causes vulnerability to physiologic stressors and an increased risk of mortality and hospitalizations. Dietary intake and quality are contributing factors to the development of frailty. The Mediterranean diet is known to be one of the healthiest eating patterns with promising health impacts for prevention.

: The volume of cardiac valve and coronary artery revascularization procedures is rising in the United States. This cross-sectional study explores ethnic disparities in mortality in cardiac surgery attributed to mechanical failures of implantable heart valves and coronary artery grafts. : We used the CDC Wide-Ranging Online Data for Epidemiologic Research Multiple Causes of Death database to identify patients whose single cause of death was categorized by complications of cardiovascular prosthetic devices, implants, and grafts (ICD-10 code T82) between 1999 and 2020.

Acute ischemic stroke with large vessel occlusion (LVO) continues to present a considerable challenge to global health, marked by substantial morbidity and mortality rates. Although definitive diagnostic markers exist in the form of neuroimaging, their expense, limited availability, and potential for diagnostic delay can often result in missed opportunities for life-saving interventions. Despite several past attempts, research efforts to date have been fraught with challenges likely due to multiple factors, such as the inclusion of diverse stroke types, variable onset intervals, differing pathobiologies, and a range of infarct sizes, all contributing to inconsistent circulating biomarker levels.

Idiopathic pulmonary fibrosis (IPF) and other progressive fibrotic interstitial lung disease have limited treatment options. Fibroblasts are key effector cells that sense matrix stiffness through conformation changes in mechanically sensitive receptors, leading to activation of downstream profibrotic pathways. Here we investigate the role of Piezo2, a mechanosensitive ion channel, in human and mouse lung fibrosis, and its function in myofibroblast differentiation in primary human lung fibroblasts (HLFs).

Objective: Inflammation contributes to morbidity following subarachnoid hemorrhage (SAH). The authors of this study evaluate how applying noninvasive transauricular vagus nerve stimulation (taVNS) can target this deleterious inflammatory response following SAH and reduce the rate of radiographic vasospasm.

Methods: In this prospective, triple-blinded, randomized controlled trial, 27 patients were randomized to taVNS or sham stimulation.

Rational: One of the important considerations to select the appropriate outcome measures is determining if the tool is relevant to patients. Despite the availability of various performance-based tests to objectively assess function, it is unknown which performance-based tests best capture important aspects of function after hip or knee arthroplasty.

Aims And Objectives: Our systematic review aimed to identify the existing performance-based tests used in hip or knee arthroplasty and link the activity component of each test to the modified International Classification of Functioning, Disability and Health (ICF) core set for osteoarthritis (OA).

The Evolving Features of Takotsubo Syndrome.

Curr Cardiol Rep

January 2025

Berne Cardiovascular Research Center and Division of Cardiology, University of Virginia, Charlottesville, USA.

Purpose Of The Review: Takotsubo syndrome (TTS) is a transient form of left ventricular dysfunction, typically affecting post-menopausal females, often preceded by emotional or physical stressful events that act as triggers. Initially believed to be a rare and benign condition for its reversible nature, TTS has recently emerged as a complex multifaceted clinical entity, with heterogenous clinical presentations and a non-negligible risk of serious in-hospital complications, including acute heart failure, arrhythmias and death.

Recent Findings: Emerging pathophysiological hypotheses, ranging from microvascular dysfunction to systemic inflammation, offer new insights into the underlying mechanisms of TTS.

Cocaine use disorder (CUD) is associated with executive functioning impairments linked to serotonergic function. Previous studies reported efficacy with the selective serotonin reuptake inhibitor citalopram in reducing cocaine use. The current study explored moderation and mediation of citalopram effects on cocaine use by performance across executive function domains.

In this conceptual article, the authors provide a narrative review of literature on bullying and sexual harassment in K-12 schools framed through a comparative analysis of risk and protective factors for both forms of violence across the social-ecological spectrum. We find that a greater number of studies of both forms of violence focus on student and microsystem-level factors rather than on higher levels of the ecosystem including school boards, neighborhoods, and broader cultural norms. In addition, the research overwhelmingly identifies more risk factors than protective factors.

The surface topography and chemistry of titanium-aluminum-vanadium (Ti6Al4V) implants play critical roles in the osteoblast differentiation of human bone marrow stromal cells (MSCs) and the creation of an osteogenic microenvironment. To assess the effects of a microscale/nanoscale (MN) topography, this study compared the effects of MN-modified, anodized, and smooth Ti6Al4V surfaces on MSC response, and for the first time, directly contrasted MN-induced osteoblast differentiation with culture on tissue culture polystyrene (TCPS) in osteogenic medium (OM). Surface characterization revealed distinct differences in microroughness, composition, and topography among the Ti6Al4V substrates.

The case for value-based care in kidney transplantation: insights into geography, growth, and financial models.

Curr Opin Organ Transplant

January 2025

Department of Pharmacotherapy & Outcomes Science, School of Pharmacy, Virginia Commonwealth University, Richmond, Virginia, USA.

Purpose Of Review: Kidney transplantation (KT) is the preferred treatment for end-stage renal disease (ESRD), yet systemic challenges, including geographic disparities, impede equitable access. This review evaluates transplant center activity and regional disparities using recent trends and discusses the potential of value-based care (VBC) models like the proposed Increasing Organ Transplant Access (IOTA) model to address these challenges.

Recent Findings: Analysis of Organ Procurement and Transplantation Network (OPTN) data from 2021 to 2023 identified 185 of 322 transplant centers as potentially eligible for VBC inclusion.

Black Americans with Posttraumatic Stress Disorder have less access to mental healthcare compared to White Americans. Many factors contribute to this inequity, including broader disparities within the healthcare system driven by systemic racism, and an underutilization of mental health services by Black Americans due to provider bias and stigma around mental health care. These disparities are rooted in a racist historical context of exclusion and abuse of the Black community by the White psychiatric establishment, and a perpetration of further trauma on Black clients, a context that is largely missing from traditional mental health education and literature on Black mental health today.

Diagnosis of cryptococcal meningitis is typically aided through CSF analysis obtained via lumbar puncture (LP), revealing elevated WBCs, increased protein, decreased glucose, and increased opening pressure. While CSF culture confirms the diagnosis, it takes days, prompting reliance on these adjuncts. AIDS from Human Immunodeficiency Virus is less commonly diagnosed in the emergency setting due to advances in testing and treatment.

Department of Chemistry, Virginia Commonwealth University, 1001 West Main Street, Richmond, VA 23284, USA.

Quinine is known for treating malaria, muscle cramps, and, more recently, has been used as an additive in tonic water due to its bitter taste. However, it was shown that excessive consumption of quinine can have severe side effects on health. In this work, we utilized fluorescence spectroscopy to measure the concentration of quinine in commercial tonic water samples.

Department of Structural Biology, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo, State University of New York, Buffalo, New York, USA.

Periodontal diseases afflict 20-50% of the global population and carry serious health and economic burdens. Chronic periodontitis is characterized by inflammation of the periodontal pocket caused by dysbiosis. This dysbiosis is coupled with an increase in the population of Treponema denticola, a spirochete bacterium with high mobility and invasivity mediated by a number of virulence factors.
