Development of posttransplant diabetes mellitus in US recipients of liver transplant is influenced by OPTN region.

Posttransplant diabetes mellitus (PTDM) is associated with significant morbidity and mortality in liver transplant recipients (LTRs). We used the Organ Procurement and Transplantation Network (OPTN) database to compare the incidence of developing PTDM across the United States and develop a risk prediction model for new-onset PTDM using OPTN region as well as donor-related, recipient-related, and transplant-related factors. All US adult, primary, deceased donor, LTRs between January 1, 2007, and December 31, 2016, with no prior history of diabetes noted, were identified.

Identifying Predictors of Successful Conversion from OREF Grants to Extramural Federal Funding Among Orthopaedic Surgeons.

Background: Musculoskeletal diseases are a major contributor to global human disability, but research in this area of medicine contends with chronic underfunding in the United States, receiving <2% of the National Institutes of Health (NIH) budget. The Orthopaedic Research and Education Foundation (OREF) serves as a vital nongovernmental organization, providing essential support for orthopaedic research. This study investigated the translation of various OREF grants into successful extramural federal funding discerning the clinician demographics and OREF award characteristics associated with increased chances of securing federal grants.

Untangling the Efficient Boron-Initialized Hydroxyl-Terminated Polybutadiene Combustion for High Energetic Solid Propulsion Systems.

Highly energetic boron (B) particles embedded in hydroxyl-terminated polybutadiene (HTPB) thermosetting polymers represent stable solid-state fuel. Laser-heating of levitated B/HTPB and pure HTPB particles in a controlled atmosphere revealed spontaneous ignition of B/HTPB in air, allowing for examination of the exclusive roles of boron. These ignition events are probed via simultaneous spectroscopic diagnostics: Raman and infrared spectroscopy, temporally resolved high-speed optical and infrared cameras, and ultraviolet-visible (UV-vis) spectroscopy.

Huddles in Hospital Maternity Settings: A Scoping Review.

Background: The Agency for Healthcare Research and Quality recommends the use of safety huddles, in which clinicians are briefly gathered to review a patient's condition, including new or developing changes in acuity or stability. The Joint Commission describes huddles as a "hallmark" of high-reliability organizations. Previous reviews have confirmed the general utility of huddles, including positive regard by clinicians, but there has not been work specifically looking at huddle use in hospital maternity care settings.

Psychometric validation of the Diagnostic Assessment Research Tool: Alcohol use disorder module.

Aims: Structured clinical interviewing is considered the gold standard in psychiatric diagnosis. The Diagnostic Assessment Research Tool (DART) is a novel modularized, non-copywritten, semi-structured interview; however, no studies have examined the psychometric properties of its alcohol use disorder (AUD) module. The primary aims of this study were to: (i) validate the factor structure of the DART AUD module and (ii) examine measurement invariance across several key demographic and subgroup factors.

Five-Year Fracture Rate for Transgender and Gender Diverse Patients on Gender-Affirming Hormone Therapy.

Introduction: Gender-affirming hormone therapy (GAHT) is a cornerstone of gender-affirming care for transgender and gender diverse (TGD) patients, with a direct biological role on bone metabolism. However, a paucity of data describes how GAHT influences fracture rate over time. The study's primary objective was to describe the 5-year all-cause fracture incidence rate (IR) among TGD patients initiating estrogen-based GAHT (E-GAHT) or testosterone-based GAHT (T-GAHT), compared with TGD patients not using GAHT (non-GAHT).

Advances in Imaging of Traumatic Nerve Injuries.

Traumatic peripheral nerve injuries represent a spectrum of conditions and remain challenging to diagnose and prognosticate. High-resolution ultrasonography and magnetic resonance neurography have emerged as useful diagnostic modalities in the evaluation of traumatic peripheral nerve and brachial plexus injuries. Ultrasonography is noninvasive, is able to rapidly interrogate large areas and multiple nerves, allows for a dynamic assessment of nerves and their surrounding anatomy, and is cost-effective.

SARS-CoV-2 SPIKE Antibody Levels can Indicate Immuno-Resilience to Re-infection: a Real-World Study.

Introduction: The use of antibody titers against SARS-CoV-2, as a method of estimating subsequent infection following infection or vaccination, is unclear. Here, we investigate whether specific levels of antibodies, as markers of adaptive immunity, can serve to estimate the risk of symptomatic SARS-CoV-2 (re-) infection.

Methods: In this real-world study, laboratory data from individuals tested for SARS-CoV-2 antibodies under routine clinical conditions were linked through tokenization to a United States medical insurance claims database to determine the risk of symptomatic/severe SARS-CoV-2 infection outcomes.

Optimizing Drug Selection in Children with Multiple Sclerosis: What Do We Know and What Remains Unanswered?

Pediatric-onset multiple sclerosis (POMS) refers to multiple sclerosis with onset before 18 years of age. It is characterized by a more inflammatory course, more frequent clinical relapses, and a greater number of magnetic resonance imaging (MRI) lesions compared with adult-onset MS (AOMS), leading to significant impacts on both disability progression and cognitive outcomes in affected individuals. Managing POMS presents distinct challenges due to the unique needs of pediatric patients and the limited number of disease-modifying therapies (DMTs) approved for pediatric use.

Electrolyte Anions Suppress Hydrogen Generation in Electrochemical CO Reduction on Cu.

In this study, we employed EC-MS to elucidate the role of halide anions in electrochemical CO2 and CO reduction. We found that the undesired hydrogen evolution reaction (HER) was significantly suppressed by the anion used. Specifically, the rates of H2 production decreased in the order KF > KCl > KI, meaning that I- most strongly suppressed HER.

The Integrin Receptors: From Discovery to Structure to Medicines.

Innate immune cells perform vital tasks in detecting, seeking, and eliminating invading pathogens, thus ensuring host survival. However, loss of function of these cells or their overactive response to tissue injury often causes serious ailments. It is, therefore, crucial to understand at a basic level how these cells function in health and disease.

Phenotypic Plasticity During Organofluorine Degradation Revealed by Adaptive Evolution.

A major factor limiting the biodegradation of organofluorine compounds has been highlighted as fluoride anion toxicity produced by defluorinating enzymes. Here, two highly active defluorinases with different activities were constitutively expressed in Pseudomonas putida ATCC 12633 to examine adaption to fluoride stress. Each strain was grown on α-fluorophenylacetic acid as the sole carbon source via defluorination to mandelic acid, and each showed immediate fluoride release and delayed growth.
