ECG Patterns of Occlusion Myocardial Infarction: A Narrative Review.

The traditional management of acute coronary syndrome has relied on the identification of ST-segment elevation myocardial infarction (STEMI) as a proxy of acute coronary occlusion. This conflation of STEMI with acute coronary occlusion has historically overshadowed non-ST-segment elevation myocardial infarction (NSTEMI), despite evidence suggesting 25% to 34% of NSTEMI cases may also include acute coronary occlusion. Current limitations in the STEMI/NSTEMI binary framework underscore the need for a revised approach to chest pain and acute coronary syndrome management.

Percutaneous VT Ablation via RA-to-LV Access in Patients With Double Mechanical Valves: A Multicenter Registry.

Background: In patients with mechanical aortic and mitral valves requiring catheter ablation of ventricular tachycardia (VT), a technique for access from the right atrium (RA) to the left ventricle (LV) via puncture of the inferoseptal process of the LV was previously described in a single-center series.

Objectives: This study sought to report the multicenter experience of VT ablation using this novel LV access approach.

Methods: We assembled a multicenter registry of patients with double mechanical valves who underwent VT ablation with RA-to-LV access.

Emerging biomarkers in Gaucher disease.

Gaucher disease (GD) is a rare lysosomal disorder characterized by the accumulation of glycosphingolipids in macrophages resulting from glucocerebrosidase (GCase) deficiency. The accumulation of toxic substrates, which causes the hallmark symptoms of GD, is dependent on the extent of enzyme dysfunction. Accordingly, three distinct subtypes have been recognized, with type 1 GD (GD1) as the common and milder form, while types 2 (GD2) and 3 (GD3) are categorized as neuronopathic and severe.

Left ventricular elastance with resting volumetric transthoracic echocardiography identifies different phenotypes in heart failure with preserved ejection fraction: A retrospective analysis of a multicenter prospective observational study.

Background: Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous entity including patients with different phenotypes of near normal, normal, and supernormal left ventricular (LV) function.

Objectives: To assess the value of resting LV elastance (also known as force) with transthoracic echocardiography (TTE) to identify HFpEF phenotypes.

Methods: In a prospective, observational, multicenter study, 2380 HFpEF patients were recruited from July 2016 to May 2024.

Knowledge of Mandatory Reporting Laws and Recording of Clients' Abuse Data: Effects of a Sexual Health Curriculum Training for Health Students in Tanzania.

Tanzania mandated reporting laws aim to identify and address child abuse, yet healthcare students' awareness and reporting are limited. This study assessed training's impact on their knowledge of reporting laws and handling confidential child abuse data. The study involved 412 medical and nursing students in a randomized controlled trial (RCT), with 206 participants receiving sexual health training and a waitlist control group of equal size receiving no intervention.

Correlating autonomic physiology with symptoms of autonomic dysreflexia after spinal cord injury.

Background: Individuals with spinal cord injury (SCI) commonly have autonomic dysreflexia (AD) with increased sympathetic activity. After SCI, individuals have decreased baroreflex sensitivity and increased vascular responsiveness.

Objective: To evaluate the relationship between baroreflex and blood vessel sensitivity with AD symptoms.

Non-Operative Management of Cholecystitis in Pregnant Patients Remains Common.

Cholecystectomy is the recommended treatment for acute cholecystitis in pregnancy, leading to fewer pregnancy-related complications than non-operative management. However, past research demonstrated high rates of non-operative management despite these recommendations. Rates of cholecystostomy tube usage and outcomes in pregnancy are not well described.

Population-Based Analysis of Late Outcomes of Mitral Valve Repair for Degenerative Mitral Valve Regurgitation.

Background: Population-based analyses may reduce uncertainty related to referral bias and/or incomplete follow-up.

Objectives: This study analyzed long-term mortality and durability of mitral valve repair in a geographically defined population with clinical and echocardiographic follow-up.

Methods: We used the Rochester Epidemiology Project to identify 153 Olmsted County patients who underwent mitral valve repair for degenerative regurgitation from 1993 to 2018.

Home-Based Cardiac Rehabilitation Among Attendees From a Large Health Care System During the Covid-19 Pandemic.

Background: Few studies have evaluated home-based cardiac rehabilitation (HBCR) during the pandemic, compared to prepandemic center-based CR (CBCR), with respect to patient characteristics, participation rates, and its efficacy on clinical metrics, health-related quality of life (QoL), and modifiable risk factors.

Objectives: We aimed to describe patient characteristics and participation rates for those attending HBCR compared to patients who attended CBCR and compare the effects of HBCR vs CBCR on clinical metrics, health-related QoL, and modifiable risk factors in CR patients pre vs during the COVID-19 pandemic.

Methods: A retrospective cohort study comparing 511 HBCR patients and 765 CBCR patients from the Mayo Clinic Health System.

This proposed scientific statement is focused on providing new insights regarding challenges and opportunities for cardiovascular health (CVH) promotion in Africa. The statement includes an overview of the current state of CVH in Africa, with a particular interest in the cardiometabolic risk factors and their evaluation through metrics. The statement also explains the main principles of primordial prevention, its relevance in reducing noncommunicable disease and the different strategies that have been effective worldwide.

Manipulation of mitochondrial poly(A) polymerase family proteins in impacts mRNA termini processing.

RNA-specific nucleotidyltransferases (rNTrs) add nontemplated nucleotides to the 3 end of RNA. Two noncanonical rNTRs that are thought to be poly(A) polymerases (PAPs) have been identified in the mitochondria of trypanosomes - KPAP1 and KPAP2. KPAP1 is the primary polymerase that adds adenines (As) to trypanosome mitochondrial mRNA 3 tails, while KPAP2 is a non-essential putative polymerase whose role in the mitochondria is ambiguous.

Recommended Opioid Receptor Tool Compounds: Comparative for Receptor Selectivity Profiles and for Pharmacological Antinociceptive Profiles.

Opioid agonist ligands bind opioid receptors and stimulate downstream signaling cascades for various biological processes including pain and reward. Historically, before cloning the receptors, muscle contraction assays using isolated organ tissues were used followed by radiolabel ligand binding assays on native tissues. Upon cloning of the opioid G protein-coupled receptors (GPCRs), cell assays using transfected opioid receptor DNA plasmids became the standard practice including S-GTPγS functional and cAMP based assays.

Osseointegration and fixation opportunities of sacroiliac instrumentation: a preclinical evaluation in a large animal model.

Background: Implant fixation is often the cornerstone of musculoskeletal surgical procedures performed to provide bony fixation and/or fusion. The aim of this study was to evaluate how different design features and manufacturing methods influence implant osseointegration and mechanical properties associated with fixation in a standardized model in cancellous bone of adult sheep.

Methods: We evaluated the performance of three titanium alloy implants: (A) iFuse-TORQ implant; (B) Fenestrated Sacroiliac Device; and (C) Standard Cancellous Bone Screw in the cancellous bone of the distal femur and proximal tibia in 8 sheep.

Increased usage of doxycycline for young children with Lyme disease.

Background: The 2018 Infectious Disease Committee of the American Academy of Pediatrics stated that up to 3 weeks or less of doxycycline is safe in children of all ages. Our goal was to examine trends in doxycycline treatment for children with Lyme disease.

Methods: We assembled a prospective cohort of children aged 1 to 21 years with Lyme disease who presented to one of eight participating Pedi Lyme Net centers between 2015 and 2023.

A Case of Atraumatic Splenic Rupture Due to T-Cell/Histiocyte-Rich Large B-Cell Lymphoma and a Potential Role for Massive Transfusion Protocol.

Splenic rupture leads to massive hemorrhage and requires immediate surgical intervention. Splenic rupture results from trauma or from underlying disease processes. Lymphoma is a rare cause of atraumatic splenic rupture (ASR) with high mortality rates.

The Two Sides of Placebo Analgesia: Differential Functional Connectivity Reveals Mechanisms of Placebo Analgesic Response.

Background: Previous research has demonstrated that placebo induction manipulations can reduce an individual's pain through non-specific mechanisms, such as expectancy manipulations. However, despite robust research characterizing these effects, individual differences in predicting placebo analgesic responses are not well understood.

Methods: Fifty-four healthy pain-free adults over 18 (M=22.

Brain aging rejuvenation factors in adults with genetic and sporadic neurodegenerative disease.

The largest risk factor for dementia is age. Heterochronic blood exchange studies have uncovered age-related blood factors that demonstrate 'pro-aging' or 'pro-youthful' effects on the mouse brain. The clinical relevance and combined effects of these factors for humans is unclear.

Participation in mainstream community groups by older United States adults with intellectual and developmental disabilities: A multiple case study.

Background: Adults with intellectual and developmental disabilities want to be included in all aspects of community life, but social inclusion continues to be very limited.

Method: We used a qualitative multiple case study to describe the experiences and perspectives of four older workers or retirees with intellectual and developmental disabilities aged 45 to 63 who each participated in a different socially inclusive community group.

Results: Three themes emerged: finding a good match; support for participation; and the outcomes of participating in a mainstream community group.

Interdisciplinarity and self-injury: Toward an inclusive research and treatment paradigm.

Background: Historically, the research and treatment of self-injury has been disciplinarily siloed. As a result, the behaviour is understood and treated differently among individuals with and without intellectual and developmental disabilities. We explore the potential for an interdisciplinary research and practice agenda in self-injury.

Fine particulate matter from burning oil and gas and associated neurological symptoms among Deepwater Horizon oil spill cleanup workers.

Burning and flaring of oil and gas following the 2010 Deepwater Horizon (DWH) oil spill generated high airborne concentrations of fine particulate matter (PM). Neurological effects of PM have been previously reported, but this relationship has received limited attention in the context of oil spills. We evaluated associations between burning-related PM and prevalence of self-reported neurological symptoms during, and 1-3 years after, the DWH disaster cleanup.
