Underserved communities were disproportionately affected during the coronavirus (COVID-19) pandemic. Limited data exist on the impact of COVID-19 among refugee populations because refugee status is not often classified in electronic medical record (EMR) systems, unlike race or primary language. The study aim was to evaluate the PCR-based prevalence of SARS-CoV-2 in a delivering population over the first 2 years of the pandemic by refugee status, ethnicity, insurance, and vaccination status.

Article Synopsis
  • The study focuses on the anatomy of the External Carotid Artery (ECA) and identifies a rare variant where the Occipital Artery (OA) and Ascending Pharyngeal Artery (APA) originate from the Internal Carotid Artery (ICA) instead of the typical ECA branches.
  • Dissection of 28 formaldehyde donors revealed this variation in one case, specifically on the right side, with a notable bifurcation angle of nearly 180 degrees.
  • The findings highlight the importance of recognizing this variation for surgeons and radiologists, improving procedural planning and reducing complications in head and neck surgeries.

Article Synopsis
  • Elevated intracranial pressure during vaginal delivery may lead to neonatal retinal hemorrhage by causing stress and deformation in the eye's structures.
  • A computational model showed how maternal contractions can displace the eye backward, inducing strain in the retina and stress on retinal vessels.
  • The study suggests that the resulting eye deformation, rather than blockage of blood vessels, is a more likely cause for this type of retinal damage in newborns.

Objective: This study used a program evaluation approach to investigate the perceptions of utilizing in-person applicant interviews for a general surgery residency program.

Design: The study utilized de-identified data routinely collected during the residency program applicant interviews in the General Surgery Residency Program during the fall of 2023. Applicant and faculty/resident exit interview questionnaires were developed to evaluate perceptions of in-person interviewing; the questions were informed by domains for considering the appropriateness and feasibility of continuing in-person interviews as identified by the institution's Graduate Medical Education Committee.

Article Synopsis
  • The increasing incidence of heat stroke due to climate change necessitates urgent strategies to combat weather-related health issues and prevent severe outcomes like organ failure.
  • The text focuses on a new protocol for cold-water immersion in emergency departments, aimed at quickly lowering core body temperatures in patients with heat stroke, particularly those with altered mental states and temperatures over 40 °C.
  • It highlights the implementation of this protocol during the summer of 2023, detailing its effectiveness, challenges faced, and the need for collaboration, education, and infrastructure improvements in emergency care.

Background: Resuscitative thoracotomies are a time-sensitive emergency surgical procedure with an immediate risk of mortality. We hypothesize that a high-fidelity whole-body donor simulation model, referred to as a Knowledge Donor (KD), with mechanical lung ventilation and expired human blood perfusion could increase learner confidence in performing this critical procedure.

Methods: General surgery residents and faculty were invited to participate in KD training.

Article Synopsis
  • Artificial intelligence in medicine usually faces challenges related to small, non-diverse patient data due to privacy concerns, but federated learning (FL) offers a solution by allowing training across different hospitals without sharing sensitive data.
  • The newly developed FL-PedBrain platform is specifically designed for pediatric brain tumors, enabling collaborative training for tumor classification and segmentation across 19 international centers, addressing the lack of diverse datasets in this area.
  • FL-PedBrain shows impressive performance metrics, maintaining almost equivalent accuracy to centralized data training while significantly improving segmentation performance by 20 to 30% at external sites, and allows for the examination of data variability in real-world situations.

Article Synopsis
  • This text is aimed at interns and junior emergency medicine residents, focusing on the importance of using transvaginal ultrasound (TVUS) in emergency departments to evaluate abdominal pain and vaginal bleeding in early pregnancy.
  • It highlights the benefits of transvaginal point-of-care ultrasound (TVPOCUS) for making quick assessments, improving patient satisfaction, and reducing costs and wait times, while also noting that emergency physicians can be trained to perform this skill safely.
  • The session's educational objectives are to help learners recognize when to use TVUS, practice performing TVPOCUS, interpret ultrasound images, and understand proper procedures for using ultrasound equipment.

Introduction: Delta-9-tetraydrocannabinol (THC) usage is associated with venous thromboembolic events (VTE) in trauma patients. We hypothesized that THC ​+ ​trauma patients would have less platelet inhibition than THC - patients using thromboelastography with platelet mapping (TEG-PM).

Methods: Results from initial TEG- PM assays and patient's UDS were reviewed between 2019 and 2023.

Deserts are defined by their arid nature, characterized by little rainfall, and often featuring vast stretches of sandy terrain with sparse vegetation. The resulting variations in temperature, humidity, and topography predispose patients to medical conditions that practitioners in both rural and urban deserts must recognize and manage. This article will equip medical practitioners with the essential knowledge and tools to navigate these complexities, including a description of specific environmental considerations and challenges encountered while providing care in these desert locations, common conditions associated with extreme heat and solar radiation, and animal encounters.

Promising immunomodulators for management of substance and alcohol use disorders.

Expert Opin Pharmacother

May 2024

Department of Psychology, Behavioral Neuroscience and Comparative Psychology Area, Arizona State University, Tempe, Arizona, USA.

Introduction: The neuroimmune system has emerged as a novel target for the treatment of substance use disorders (SUDs), with immunomodulation producing encouraging therapeutic benefits in both preclinical and clinical settings.

Areas Covered: In this review, we describe the mechanism of action and immune response to methamphetamine, opioids, cocaine, and alcohol. We then discuss off-label use of immunomodulators as adjunctive therapeutics in the treatment of neuropsychiatric disorders, demonstrating their potential efficacy in affective and behavioral disorders.

Progressive supranuclear palsy (PSP) is a neurodegenerative disorder resulting from the deposition of misfolded and neurotoxic forms of tau protein in specific areas of the midbrain, basal ganglia, and cortex. It is one of the most representative forms of tauopathy. PSP presents in several different phenotypic variations and is often accompanied by the development of concurrent neurodegenerative disorders.

Breast-conserving surgery (BCS) is a well-established standard treatment option alternative to mastectomy for patients with early breast cancer that consists of a lumpectomy followed by adjuvant radiotherapy. However, irradiated tissues are at an increased risk of wound healing complications when post-treatment surgical management is required. The management of an irradiated wound dehiscence can be challenging, as it often requires a multimodal treatment approach that includes more invasive interventions when compared to a traditional surgical wound dehiscence.
