Association between beta-blocker atenolol use and prostate cancer upgrading in active surveillance.

Objectives: The objective of this study is to investigate the association between the use of beta-adrenergic antagonist atenolol and risk of pathologic upgrade in patients on active surveillance, considering growing literature implicating adrenergic innervation with disease progression mediated through beta-adrenergic signalling.

Patients And Methods: Men with low-risk or favourable intermediate-risk prostate cancer who were placed on an active surveillance protocol between 2006 and 2020 across three diverse urban hospitals were included. Exposure was duration of atenolol use, and outcome was pathologic grade group upgrading (to GG ≥ 3) on final prostate biopsy.

Two prospective, multicenter studies for the identification of biomarker signatures for early detection of pulmonary hypertension (PH): The CIPHER and CIPHER-MRI studies.

A blood test identifying patients at increased risk of pulmonary hypertension (PH) could streamline the investigative pathway. The prospective, multicenter CIPHER study aimed to develop a microRNA-based signature for detecting PH in breathless patients and enrolled adults with a high suspicion of PH who had undergone right heart catheterization (RHC). The CIPHER-MRI study was added to assess the performance of this CIPHER signature in a population with low probability of having PH who underwent cardiac magnetic resonance imaging (cMRI) instead of RHC.

Posterior spinal fusion for adolescent idiopathic scoliosis and the impact of postoperative intravenous dexamethasone supplementation.

Postoperative care pathways for adolescent idiopathic scoliosis patients undergoing posterior spinal fusion have demonstrated decreases in postoperative opioid consumption, improved pain control, and lead to decreased lengths of stay. Our objective was to implement postoperative steroids to reduce acute postoperative opioid consumption, pain scores, and length of stay. Dosing consisted of intravenous dexamethasone 0.

"Cold feet": A qualitative study of medical students who seriously considered emergency medicine but chose another specialty.

Introduction: Emergency medicine (EM) has historically been among the most competitive specialties in the United States. However, in 2022 and 2023, 219 of 2921 and 554 of 3010 respective National Resident Matching Program positions were initially unfilled. Medical students' selection of a medical specialty is a complex process.

Intra-arrest blood-based biomarkers for out-of-hospital cardiac arrest: A scoping review.

Objective: Blood-based biomarkers play a central role in the diagnosis and treatment of critically ill patients, yet none are routinely measured during the intra-arrest phase of out-of-hospital cardiac arrest (OHCA). Our objective was to describe methodological aspects, sources of evidence, and gaps in research surrounding intra-arrest blood-based biomarkers for OHCA.

Methods: We used scoping review methodology to summarize existing literature.

Methods: Eligibility, consent, and randomization rates across different referral sources were compared. Informal interviews conducted with each site's project team were conducted upon study completion.

The prevalence of frailty and its relationship with sociodemographic factors, regional healthcare disparities, and healthcare utilization in the aging population across India.

Objective: To estimate frailty prevalence and its relationship with the socio-economic and regional factors and health care outcomes.

Methods: In this study, participants from the harmonized Diagnostic Assessment of Dementia for the Longitudinal Aging Study in India (LASI-DAD) were included. The frailty index (FI) was calculated using a 32-variable deficit model, with a value of ≥ 25% considered as frail.

From inequity to access: Evidence-based institutional practices to enhance care for individuals with disabilities.

People with disabilities experience barriers to care in all facets of health care, from engaging with the provider in a clinical setting (attitudinal and communication barriers) to navigating a large institution in a complex health care environment (organizational and environmental barriers), culminating in significant health care disparities. Institutional policy, culture, and physical layout may be inadvertently fostering ableism, which can perpetuate health care inaccessibility and health disparities in the disability community. Here, we present evidence-based interventions at the provider and institutional levels to accommodate patients with hearing, vision, and intellectual disabilities.

Nanodrugs with intrinsic radioprotective exertion: Turning the double-edged sword into a single-edged knife.

Ionizing radiation (IR) poses a growing threat to human health, and thus ideal radioprotectors with high efficacy and low toxicity still receive widespread attention in radiation medicine. Despite significant progress made in conventional radioprotectants, high toxicity, and low bioavailability still discourage their application. Fortunately, the rapidly evolving nanomaterial technology furnishes reliable tools to address these bottlenecks, opening up the cutting-edge nano-radioprotective medicine, among which the intrinsic nano-radioprotectants characterized by high efficacy, low toxicity, and prolonged blood retention duration, represent the most extensively studied class in this area.

Electrophysiological Characterization of a Variant with Tremor Phenotype.

Background: The concept of a myopathy with associated tremor ("myogenic tremor") in humans has been previously described for specific (Myosin-Binding Protein C) variants. Here we report for the first time an individual with tremor who was found to have a de-novo likely pathogenic variant in Myosin Heavy Chain 7 (MYH7

Unlabelled: We provide a detailed electrophysiological characterization of the tremor syndrome in a human individual with a myopathy and this pathogenic MYH7 variant to provide further insight in the phenotypic spectrum and pathomechanism of myogenic tremors in skeletal sarcomeric myopathies.

Methods: Electromyographic recordings were obtained from facial muscles, as well as bilateral upper and lower extremities.

Prognosis of pulmonary arterial hypertension patients with pericardial effusion before and after initiation of parenteral prostacyclin therapy.

Few studies have evaluated the effects of pulmonary arterial hypertension therapies on pericardial effusion. We evaluated hemodynamics, echocardiograms, and outcomes for 119 parenteral prostanoid-treated patients. We discovered an increased frequency of pericardial effusions posttreatment, and that a moderate-large pericardial effusion at initiation, but not at 1st follow-up, was significantly associated with mortality.

Arginase 1 Deficiency in Patients Initially Diagnosed with Hereditary Spastic Paraplegia.

Background: Arginase 1 Deficiency (ARG1-D) is a rare autosomal recessive urea cycle disorder (UCD) characterized by pathologic elevation of plasma arginine and debilitating manifestations. Based on clinical commonalities and low disease awareness, ARG1-D can be diagnosed as hereditary spastic paraplegia (HSP), leading to treatment delays.

Cases: A Hispanic woman with unremarkable medical history experienced progressive lower-limb spasticity in her 20s and received a diagnosis of HSP.

Protein profiling by reverse phase protein array (RPPA) in classical hairy cell leukemia (HCL) and HCL-variant.

Classical hairy cell leukemia (HCL-c) and HCL variant (HCL-v) are recognized as separate entities with HCL-v having significantly shorter overall survival. Proteomic studies, shown to be prognostic in various forms of leukemia, have not been performed in HCL. We performed reverse phase protein array-based protein profiling with 384 antibodies in HCL-c ( = 12), HCL-v ( = 4), and normal B-cells ( = 5) samples.

Macitentan is an oral endothelin receptor antagonist for the management of pulmonary arterial hypertension (PAH). The OPsumit® USers Registry (OPUS) and the OPsumit® Historical USers cohort (OrPHeUS) medical chart review provide real-world data for patients newly initiating macitentan. This study aims to describe the characteristics, safety profile, and clinical outcomes of PAH patients newly treated with macitentan in the combined OPUS/OrPHeUS data set.

An artificial intelligence system applied to recurrent cytogenetic aberrations and genetic progression scores predicts rearrangements in large B-cell lymphoma.

Diffuse large B-cell lymphoma (DLBCL), the most common type of non-Hodgkin lymphoma, is characterized by rearrangements ( R) in up to 15% of cases, and these have unfavorable prognosis. Due to cryptic rearrangements and variations in breakpoints, R may be undetectable by conventional methods in up to 10%-15% of cases. In this study, a retrospective proof of concept study, we sought to identify recurrent cytogenetic aberrations (RCAs), generate genetic progression scores (GP) from RCAs and apply these to an artificial intelligence (AI) algorithm to predict status in the karyotypes of published cases.

Emergency care of LGBTQIA+ patients requires more than understanding the acronym.

Emergency physicians (EPs) frequently deliver care to members of the LGBTQIA+ community in the emergency department. This community suffers from many health disparities important to understand as part of comprehensive care, and these disparities are infrequently discussed in emergency medicine education. Previous data also suggest a need for broader education to increase the comfort of EPs caring for LGBTQIA+ patients.
