Objective: To examine the relationship between body mass index (BMI), newly developed sleep disorders and functional outcome after moderate-to-severe traumatic brain injury (msTBI).

Methods: Retrospective data from the TBI Model Systems National Database was analyzed, focusing on the independent association between BMI, sleep disorder diagnosis, and functional outcome as measured by the Extended Glasgow Outcome Scale (GOSE) at 1-year post-injury. Linear and logistic regression were used.

Background: Recurrent weight gain (RWG) is a major post-operative challenge among metabolic and bariatric surgery (MBS) patients. Binge eating behaviours (BEB) and food addiction (FA) have been identified as significant predictors of post-MBS RWG. However, limited research has investigated their independent associations with post-MBS RWG.

Introduction: Whole blood resuscitation is associated with survival benefits in observational cohort studies. The mechanisms responsible for outcome benefits have not been adequately determined. We sought to characterize the achievement of hemostasis across patients receiving early whole blood versus component resuscitation.

Prokaryotic heme biosynthesis in Gram-positive bacteria follows the coproporphyrin-dependent heme biosynthesis pathway. The last step in this pathway is catalyzed by the enzyme coproheme decarboxylase, which oxidatively transforms two propionate groups into vinyl groups yielding heme b. The catalytic reaction cycle of coproheme decarboxylases exhibits four different states: the apo-form, the substrate (coproheme)-bound form, a transient three-propionate intermediate form (monovinyl, monopropionate deuteroheme; MMD), and the product (heme b)-bound form.

Polymyxins are last-resort antimicrobial peptides administered clinically against multi-drug resistant bacteria, specifically in the case of Gram-negative species. However, an increasing number of these pathogens employ a defense strategy that involves a relay of enzymes encoded by the pmrE (ugd) loci and the arnBCDTEF operon. The pathway modifies the lipid-A component of the outer membrane (OM) lipopolysaccharide (LPS) by adding a 4-amino-4-deoxy-l-arabinose (L-Ara4N) headgroup, which renders polymyxins ineffective.

Data regarding cardiogenic shock (CS) from safety-net hospitals serving socioeconomically-disadvantaged patients are limited. In addition, little is known regarding long-term outcomes and management of heart failure-related CS (HF-CS), a population potentially especially vulnerable to adverse social determinants of health (SDOH). A single-center retrospective cohort study of patients with Stage C, D, or E CS at a public safety-net hospital between 2017-2023 was performed.

Baseline and outcome stereoacuity of children with anisometropic amblyopia undergoing dichoptic amblyopia treatment.

J AAPOS

January 2025

Pediatric Vision Laboratory, Retina Foundation of the Southwest, Dallas, Texas; Optometry & Vision Science, University of Waterloo, Waterloo, Ontario, Canada.

Background: One rationale for dichoptic amblyopia therapy is that it may promote recovery of binocular function. Yet data on binocular outcomes in anisometropic amblyopia following dichoptic therapy are sparse. We report factors associated with pre- and post-treatment binocular function in anisometropic amblyopia, and examine binocular function in children who recover normal visual acuity compared to those with residual amblyopia.

Department of Psychiatry, Beth Israel Deaconess Medical Center, Boston, MA, USA; Department of Psychiatry, Harvard Medical School, Boston, MA, USA. Electronic address:

Background: Past studies associating personality with psychosis have been limited by small nonclinical samples and a focus on general symptom burden. This study uses a large clinical sample to examine personality's relationship with psychosis-specific features and compare personality dimensions across clinically and neurobiologically defined categories of psychoses.

Methods: A total of 1352 participants with schizophrenia, schizoaffective disorder, and bipolar with psychosis, as well as 623 healthy controls (HC), drawn from the Bipolar-Schizophrenia Network for Intermediate Phenotypes (BSNIP-2) study, were included.

Introduction: In NCCN favorable intermediate-risk (FIR) prostate cancer (PCa) patients treated with radical prostatectomy (RP), we tested the effect of upstaging and upgrading on cancer-specific mortality (CSM).

Methods: Within the SEER database (2010-2021), upstaging (≥pT3a or pN1) and upgrading (ISUP ≥3) rates in FIR RP patients were tabulated. Kaplan-Meier (KM) plots and multivariable Cox-regression models (CRMs) were fitted.

The Role of Imaging in Pulmonary Vascular Disease: The Clinician's Perspective.

Radiol Clin North Am

Pulmonary vascular diseases, particularly when accompanied by pulmonary hypertension, are complex disorders often requiring multimodal imaging for diagnosis and monitoring. Echocardiography is the primary screening tool for pulmonary hypertension, while cardiac MR imaging (CMR) is used for more detailed characterization and risk stratification in right ventricular failure. Chest computed tomography (CT) is used to detect vascular anomalies and parenchymal lung diseases.

Objective: Metabolic reprogramming plays a critical role in modulating the innate and adaptive immune response, but its role in cutaneous autoimmune diseases, such as cutaneous lupus erythematosus (CLE), is less well studied. An improved understanding of the metabolic pathways dysregulated in CLE may lead to novel treatment options, biomarkers and insights into disease pathogenesis. The objective was to compare metabolomic profiles in the skin and sera of CLE and control patients using liquid chromatography-mass spectrometry (LC-MS).

Background: The etiology of status epilepticus (SE) in Tibet has not yet been reported. We aimed to establish the etiological baseline of SE in the Tibet Autonomous Region in China and compare it with a SE cohort from a regional neuroscience centre in Sichuan, Southwestern China to reveal whether there was a unique etiology distribution in the Tibetan region.

Methods: We retrospectively captured clinical data of patients diagnosed with SE in the People's Hospital of Xizang Autonomous Region from January 2015 to December 2020.

Testing for myelin oligodendrocyte glycoprotein immunoglobulin G antibodies (MOG-IgG) is essential to the diagnosis of MOG antibody-associated disease (MOGAD). Due to its central role in the evaluation of suspected inflammatory demyelinating disease, the last 5 years has been marked by an abundance of research into MOG-IgG testing ranging from appropriate patient selection, to assay performance, to utility of serum titers as well as cerebrospinal fluid (CSF) testing. In this review, we synthesize current knowledge pertaining to the "who, what, where, when, why, and how" of MOG-IgG testing, with the aim of facilitating accurate MOGAD diagnosis in clinical practice.

Vitiligo is a chronic autoimmune pigmentation disorder shaped by a complex interplay of genetic predispositions and environmental triggers. While conventional therapies-phototherapy, corticosteroids, and immunosuppressants-can be effective, their benefits are often partial and temporary, with recurrence common once treatment stops. As such, there is increasing interest in exploring complementary approaches that may offer a more sustainable impact.
