Increasing Care for Underserved Communities Through a Global Health Residency Training Program.

Global health education is important for addressing health inequities nationally and internationally. Physician shortages in underserved areas suggest more exposure during training is needed. To study the impact of a global health training program on residents' perceived preparedness and intention to care for underserved populations.

ApoA-I binding protein (AIBP) regulates transient receptor potential vanilloid 1 (TRPV1) activity in rat dorsal root ganglion neurons by selective disruption of toll-like receptor 4 (TLR4)-lipid rafts.

Toll-like receptor 4 (TLR4) and the transient receptor potential vanilloid subtype 1 (TRPV1) are both upregulated and play key roles in the induction and expression of paclitaxel-related chemotherapy-induced peripheral neuropathy (CIPN). Using Apolipoprotein A-I binding protein, non-specific cholesterol depletion, TLR4 mis-sense rats and a TLR4 inhibitor, we demonstrate that co-localization of TRPV1 with TLR4 to cholesterol-rich lipid membrane rafts in nociceptors is essential for its normal activation as well as for its exaggerated activation that underlies the development and expression of CIPN. The findings suggest that TLR4-lipid rafts may have an essential role in numerous neuroinflammatory and neuropathic pain conditions.

Electrophysical cardiac remodeling at the molecular level: Insights into ryanodine receptor activation and calcium-induced calcium release from a stochastic explicit-particle model.

We present the first-ever, fully discrete, stochastic model of triggered cardiac Ca dynamics. Using anatomically accurate subcellular cardiac myocyte geometries, we simulate the molecular players involved in Ca handling using high-resolution stochastic and explicit-particle methods at the level of an individual cardiac dyadic junction. Integrating data from multiple experimental sources, the model not only replicates the findings of traditional in silico studies and complements in vitro experimental data but also reveals new insights into the molecular mechanisms driving cardiac dysfunction under stress and disease conditions.

Perioperative Quality Improvement in Children's Hospitals Neonatal Consortium NICUs.

Infants admitted to NICUs in children's hospitals represent a different population than those in a traditional birth hospital. The patients in a children's hospital NICU often have the most complex neonatal diagnoses and are cared for by various subspecialists. The Children's Hospitals Neonatal Consortium is a collaborative of more than 40 NICUs that collect data and perform quality improvement (QI) work across the United States and Canada.

Neighborhood environments and psychological distress 6-years later: results from the San Diego HCHS/SOL community and surrounding areas study.

Purpose: The current study examined associations of social and built features of neighborhood environments with psychological distress 6 years later and whether these associations were explained by stress and social factors, among Hispanic/Latino adults from the HCHS/SOL and SOL CASAS Ancillary Study.

Methods: In the SOL CASAS Ancillary Study, HCHS/SOL San Diego participants' baseline (2008-2011) home addresses were geocoded, neighborhoods were defined using 800 m radial buffers, and variables representing neighborhood socioeconomic deprivation, social disorder, walkability, and greenness were created. Psychological distress (anxiety and depression symptoms) and proposed pathway variables chronic stress, social support, and family cohesion were assessed at HCHS/SOL Visit 2 (2014-2017).

Treatment of Refractory Osteochondral Lesions of the Talus with a Novel Transmalleolar Drilling Technique: A Case Report.

Case: A 15-year-old adolescent girl underwent revision surgery for a posteromedial osteochondral lesion of the talus (OLT). To provide anatomic reduction of her lesion, fluoroscopy and ankle arthroscopy facilitated a transmalleolar tunnel for screw fixation. Now, 8 years after surgery, the patient reports high patient satisfaction and pain-free functional use of her ankle.

Impact of Lymph Node Dissection for Patients With Clinically Node-Negative Intrahepatic Cholangiocarcinoma: A Multicenter Cohort Study.

Background: Lymph node status is a prominent prognostic factor for intrahepatic cholangiocarcinoma (ICC). However, the prognostic value of performing lymph node dissection (LND) in patients with clinical node-negative ICC remains controversial. The aim of this study was to evaluate the clinical value of LND on long-term outcomes in this subgroup of patients.

Targeting of REST with rationally-designed small molecule compounds exhibits synergetic therapeutic potential in human glioblastoma cells.

Background: Glioblastoma (GBM) is an aggressive brain cancer associated with poor prognosis, intrinsic heterogeneity, plasticity, and therapy resistance. In some GBMs, cell proliferation is fueled by a transcriptional regulator, repressor element-1 silencing transcription factor (REST).

Results: Using CRISPR/Cas9, we identified GBM cell lines dependent on REST activity.

Health Risks of Unaccompanied Immigrant Children in Federal Custody and in US Communities.

Unaccompanied immigrant children continue to arrive at the US-Mexico border and are at high risk for ongoing abuse, neglect, and poor mental and physical health. We are medical and legal experts in the fields of immigrant and refugee health, child abuse, and the legal rights of international refugee and migrant children. We provide an overview of US federal agencies with custody of unaccompanied immigrant children, a summary of medical care provided while in custody, and recent findings from the independent mandating new custodial conditions for immigrant children while in federal custody.

Integrated Genomic and Social Network Analyses of SARS-CoV-2 Transmission in the Healthcare Setting.

Background: Infection prevention (IP) measures are designed to mitigate the transmission of pathogens in healthcare. Using large-scale viral genomic and social network analyses, we determined if IP measures used during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic were adequate in protecting healthcare workers (HCWs) and patients from acquiring SARS-CoV-2.

Methods: We performed retrospective cross-sectional analyses of viral genomics from all available SARS-CoV-2 viral samples collected at UC San Diego Health and social network analysis using the electronic medical record to derive temporospatial overlap of infections among related viromes and supplemented with contact tracing data.

The Evolve to Next-Gen ACT Network: An evolving open-access, real-world data resource primed for real-world evidence research across the Clinical and Translational Science Award Consortium.

The ACT Network was funded by NIH to provide investigators from across the Clinical and Translational Science Award (CTSA) Consortium the ability to directly query national federated electronic health record (EHR) data for cohort discovery and feasibility assessment of multi-site studies. NIH refunded the program for expanded research application to become "Evolve to Next-Gen ACT" (ENACT). In parallel, the US Food and Drug Administration has been evaluating the use of real-world data (RWD), including EHR data, as sources of real-world evidence (RWE) for its regulatory decisions involving drug and biological products.

Safety and acute efficacy of catheter ablation for atrial fibrillation with pulsed field ablation vs thermal energy ablation: A meta-analysis of single proportions.

Background: Pulsed field ablation (PFA) has emerged as a novel energy source for the ablation of atrial fibrillation (AF) using ultrarapid electrical pulses to induce cell death via electroporation.

Objective: The purpose of this study was to compare the safety and acute efficacy of ablation for AF with PFA vs thermal energy sources.

Methods: We performed an extensive literature search and systematic review of studies that evaluated the safety and efficacy of ablation for AF with PFA and compared them to landmark clinical trials for ablation of AF with thermal energy sources.

The Impact of Spine Pathology on Posterior Ligamentous Complex Structure and Function.

Purpose Of Review: Spinal ligament is an important component of the spinal column in mitigating biomechanical stress. Particularly the posterior ligamentous complex, which is composed of the ligamentum flavum, interspinous, and supraspinous ligaments. However, research characterizing the biomechanics and role of ligament health in spinal pathology and clinical context are scarce.
