Neuroinflammation underlies the development of social stress induced cognitive deficit in male sickle cell mice.

Cognitive deficit is a debilitating complication of sickle cell disease (SCD), with a multifactorial etiopathogenesis. Here we show that neuroinflammation and dysregulation in lipidomics and transcriptomics profiles are major underlying mechanisms of social stress-induced cognitive deficit in SCD. Male Townes sickle cell (SS) mice and controls (AA) were exposed to social stress using the repeat social defeat (RSD) paradigm concurrently with or without treatment with minocycline.

Endoscopic cystostomy and biliary sphincterotomy for choledochoceles: A pediatric case series.

Management of choledochoceles (type III choledochal cysts) in children varies. We highlight the potential role of endoscopic management of choledochoceles with cystostomy and biliary sphincterotomy through a series of three successfully treated pediatric patients aged 12-13 at our tertiary center. Patients presented with symptoms including abdominal pain and pancreatitis.

Patterns, Barriers, and Preferences of Treating Migraine Within the School Setting: A Survey Study of Students.

Migraine affects 10% of adolescents and children. Typical school protocols in the USA require pharmacological medications to be administered by school nurses, often resulting in treatment delays or omissions when migraine attacks occur during school hours. The Remote Electrical Neuromodulation (REN) wearable is an FDA-cleared smartphone-controlled device delivering acute and preventive treatment of migraine attacks in patients aged 8 and above, allowing safe, effective, discreet, and independent usage.

Public Board Score Reporting Undermines Holistic Review for Residency Selection.

Holistic review has become the gold standard for residency selection. As a result, many programs are de-emphasizing standardized exam scores and other normative metrics. However, if standardized exam scores predict passing of an initial certifying exam, this may lead to an increase in board failure rates within specific residency training programs who do not emphasize test scores on entry.

and variants are the underlying cause of Perrault-like syndrome and cardiac anomalies in a patient.

Recent studies have established an association between variants and Perrault syndrome. In this case report, we present a female patient with Perrault syndrome and cardiomyopathy, resulting from variants in and , respectively.

Facile construction of dual-response super-resolution probes for tracking organelles dynamics.

Super-resolution imaging techniques, such as structured illumination microscopy (SIM), have enabled researchers to obtain nanoscale organelle-level outputs in living systems, but they impose additional stringent requirements on fluorescence probes. However, high-performance, custom-designed SIM probes that can explain underlying biological processes remain unavailable. Herein, a customizable engineering toolkit is developed for the facile assembly of SIM probes suitable for subcellular component detection.

Sustainable synthesis of carbon dots via bio-waste recycling for biomedical imaging.

Bio-waste is a side product of biomedical research containing carbon, which can be utilized for developing carbon dots (CDs). CDs are known to be useful for a variety of applications because of their unique photoluminescence, low toxicity, and straightforward synthesis. In this paper, we employed a one-step hydrothermal method to prepare CDs from bio-waste as the only reactant.

Educator's blueprint: Key considerations for using social media in survey-based medical education research.

In this paper, we present a set of recommendations for using social media as a tool for participant recruitment in survey-based medical education research. Drawing from a limited but growing body of literature, we discuss the opportunities and challenges inherent to social media recruitment. This article builds on the authors' previous educator's blueprints about survey design and administration.

Patient perspectives on international multidisciplinary consensus criteria for chronic rhinosinusitis disease control.

Objectives: Recently, a set of consensus criteria and near-consensus criteria for the evaluation of chronic rhinosinusitis (CRS) disease control was identified by an international multidisciplinary panel of key stakeholders. The objective of this study is to evaluate patient perspectives on these disease control criteria.

Methods: This is a qualitative phenomenological study using constant comparative methodology.

Validity in the Next Era of Assessment: Consequences, Social Impact, and Equity.

Validity has long held a venerated place in education, leading some authors to refer to it as the "sine qua non" or "cardinal virtue" of assessment. And yet, validity has not held a fixed meaning; rather it has shifted in its definition and scope over time. In this Eye Opener, the authors explore if and how current conceptualizations of validity fit a next era of assessment that prioritizes patient care and learner equity.

Scoping review of post-TB pulmonary vascular disease: Proceedings from the 2nd International Post-Tuberculosis Symposium.

Tuberculosis (TB) may cause significant long-term cardiorespiratory complications, of which pulmonary vascular disease is most under-recognized. TB is rarely listed as a cause of pulmonary hypertension (PH) in most PH guidelines, yet PH may develop at various stages in the time course of TB, from active infection through to the post-TB period. Predisposing risk factors for the development of PH are likely multifactorial, involving active TB disease and post-TB lung disease (PTLD), host-related and environment-related factors.

Are interns prepared? A summary of current transition to residency preparation courses content.

Background: The transition from medical student to emergency medicine resident is a critical point in training. Medical students start residency with different levels of understanding and some are not meeting the emergency medicine (EM) Level 1 milestones. Residency preparation courses (RPCs) were created to fill this gap and prepare medical students for residency.

Manometric findings in children with eosinophilic esophagitis and persistent post-remission dysphagia.

Objectives: Dysphagia is a frequent symptom of active eosinophilic esophagitis (EoE), but at times it persists despite attaining histologic healing and lack of fibro-stenotic changes. We aimed to describe the manometric findings in this subset of patients.

Methods: A retrospective review of charts between 2013 and 2023 at a tertiary pediatric gastroenterology center, treating roughly 1500 EoE patients per year.

Infant versus noninfant formulas and cow's milk: Transition based on age or weight?

Infant formulas are meant to be used until 1 year of age, at which point children are transitioned to non-infant formulas or cow's milk, depending on their remaining dietary intake. Noninfant formulas and cow's milk are appropriate for children who have an average weight at that 1-year mark (9-9.5 kg); however, can contribute significant protein and/or electrolytes to children who are underweight for age, particularly if they still rely heavily on formula feeding for their caloric intake.

3D-printed neck phantoms with detailed anatomy for ultrasound-guided procedure and device testing.

Objectives: With rapid advances in ultrasound-guided procedures, there is an unmet need for echogenic phantoms with sufficient anatomical details for artificial intelligence and ultrasound-guided device testing. We developed a method for creating neck phantoms for novel otolaryngology-related device testing. To achieve accurate representation of the anatomy, we utilized CT scans and 3D printing technology to create customized agar molds, thus providing high-fidelity yet cost-effective tools.

Toward once-monthly insulin therapy synergy in two pharmacokinetic protractors: Fc-conjugation and fatty acid acylation.

Pharmacokinetic properties and duration of therapeutic action of a pharmaceutical agent can be significantly extended through the combination of two distinct strategies aimed at increasing plasma half-life: fatty acid acylation and Fc-conjugation. Using insulin as a case study, we demonstrate that a doubly protracted insulin analog produces a substantial prolongation of pharmacodynamic effect to lower blood glucose in STZ-treated mice when compared to the Fc-only counterparts. This enhancement is further corroborated by direct pharmacokinetic measurements in rat and dog models, demonstrating the potential for once-monthly insulin therapy.

A regional learning health system of congregate care facilities for COVID-19 response.

Introduction: The COVID-19 pandemic disproportionately affected congregate care (CC) facilities due to communal living, presence of vulnerable populations, inadequate preventive resources, and limited ability to respond to the pandemic's rapidly evolving phases. Most facilities function independently and are not organized for collaborative learning and operations.

Methods: We formed a learning health system of CC facilities in our 14-county metropolitan region, coordinated with public health and health care sectors, to address challenges driven by COVID-19.
