Management of partial extensor tendon lacerations of the hand and forearm: A national survey of practice in the United Kingdom.

Background: Partial extensor tendon lacerations of the hand and forearm are common. There is a lack of evidence to guide their management and it is also unclear at what threshold surgeons would consider repair necessary. This study aimed to identify national surgical management of partial extensor tendon lacerations of the hand and forearm (zones 2-8) and assess surgeons' willingness to randomise in a future trial.

Conceptualizations of Mental Health Among Young Black Gay, Bisexual, and Other Men (YB-GBMSM) Who Have Sex With Men Who Are Living With HIV.

Young Black gay, bisexual, and other men who have sex with men who are living with HIV are at an increased risk of experiencing poor mental health due to their exposures to intersectional stigma and discrimination, but often do not seek traditional mental health care. We qualitatively explored conceptualizations of mental health through interviews with 40 participants and analyzed our data using a phenomenology-informed approach. Participants conceptualized mental health as having inward-facing (cultivation of a healthy relationship with oneself, maintaining a peaceful state of mind, lack of depressed mood) and outward-facing components (goal-oriented behavior, resilient coping mechanisms).

Improving processing fluency to encourage family health information seeking: The mediating role of communication efficacy.

Drawing from the metacognitive literature, this experimental study examines how the relative ease of retrieving information (i.e. processing fluency) impacts individuals' efficacy about engaging in family health discussions and interpersonal information seeking intention across two health topics: family organ donation status and family health history.

S100A1ct: A Synthetic Peptide Derived From S100A1 Protein Improves Cardiac Performance and Survival in Preclinical Heart Failure Models.

Background: The EF-hand Ca sensor protein S100A1 has been identified as a molecular regulator and enhancer of cardiac performance. The ability of S100A1 to recognize and modulate the activity of targets such as SERCA2a (sarcoplasmic reticulum Ca ATPase) and RyR2 (ryanodine receptor 2) in cardiomyocytes has mostly been ascribed to its hydrophobic C-terminal α-helix (residues 75-94). We hypothesized that a synthetic peptide consisting of residues 75 through 94 of S100A1 and an N-terminal solubilization tag (S100A1ct) could mimic the performance-enhancing effects of S100A1 and may be suitable as a peptide therapeutic to improve the function of diseased hearts.

Alcohol and mortality in Mexico: prospective study of 150 000 adults.

Background: Alcohol consumption is a leading cause of premature death globally, but there is no large-scale prospective evidence from Mexico.

Methods: The Mexico City Prospective Study recruited 150 000 adults aged 35 years or older between 1998 and 2004. Participants were followed up until Oct 1, 2022 for cause-specific mortality.

Clonality contributes to the spread of Avrainvillea lacerata (Bryopsidales, Chlorophyta) in Hawai'i.

The relative rates of sexual versus asexual reproduction influence the partitioning of genetic diversity within and among populations. During range expansions, asexual reproduction often facilitates colonization and establishment. The arrival of the green alga Avrainvillea lacerata has caused shifts in habitat structure and community assemblages since its discovery in 1981 offshore of O'ahu, Hawai'i.

Who says what to whom through what channel? Formative communication research on antibiotic resistance messaging for urgent care patients.

Objective: To explore the source, message, channel, and receiver effects on patient concern for antibiotic resistance, willingness to reduce antibiotic use, and expectations for an antibiotic prescription in a prepandemic sample.

Methods: We used data reported from a national cross-sectional survey of adults who had visited an urgent care center within the last year. Data were collected from April 4 to April 9, 2017.

Multiresolution molecular dynamics simulations reveal the interplay between conformational variability and functional interactions in membrane-bound cytochrome P450 2B4.

Cytochrome P450 2B4 (CYP 2B4) is one of the best-characterized CYPs and serves as a key model system for understanding the mechanisms of microsomal class II CYPs, which metabolize most known drugs. The highly flexible nature of CYP 2B4 is apparent from crystal structures that show the active site with either a wide open or a closed heme binding cavity. Here, we investigated the conformational ensemble of the full-length CYP 2B4 in a phospholipid bilayer, using multiresolution molecular dynamics (MD) simulations.

Computational screening of the effects of mutations on protein-protein off-rates and dissociation mechanisms by τRAMD.

The dissociation rate, or its reciprocal, the residence time (τ), is a crucial parameter for understanding the duration and biological impact of biomolecular interactions. Accurate prediction of τ is essential for understanding protein-protein interactions (PPIs) and identifying potential drug targets or modulators for tackling diseases. Conventional molecular dynamics simulation techniques are inherently constrained by their limited timescales, making it challenging to estimate residence times, which typically range from minutes to hours.

Initial assessment and management of adults with suspected acute respiratory infection: a rapid evidence synthesis of reviews and cost-effectiveness studies.

Background: This work was undertaken to inform a National Institute for Health and Care Excellence guideline on the initial assessment of adults with suspected acute respiratory infection.

Objective: To undertake a rapid evidence synthesis of systematic reviews and cost-effectiveness studies of signs, symptoms and early warning scores for the initial assessment of adults with suspected acute respiratory infection.

Methods: MEDLINE, EMBASE and Cochrane Database of Systematic Reviews were searched for systematic reviews and MEDLINE, EMBASE, EconLit and National Health Service Economic Evaluation Database were searched for cost-effectiveness studies in May 2023.

When Fears Come True: An Experimental Approximation of Patient Comprehension During Initial Cancer Diagnoses.

Methods: A multicentre, cross-sectional retrospective study of MSFs at six centres in the UK. We collected and analyzed healthcare records, operative notes, and radiographs of adults presenting within ten days of a MSF affecting the second to fifth metacarpal between 1 August 2016 and 31 July 2017.

Devices for remote continuous monitoring of people with Parkinson's disease: a systematic review and cost-effectiveness analysis.

Background: Parkinson's disease is a brain condition causing a progressive loss of co ordination and movement problems. Around 145,500 people have Parkinson's disease in the United Kingdom. Levodopa is the most prescribed treatment for managing motor symptoms in the early stages.

Comprehensive characterization of the neurogenic and neuroprotective action of a novel TrkB agonist using mouse and human stem cell models of Alzheimer's disease.

Background: Neural stem cell (NSC) proliferation and differentiation in the mammalian brain decreases to minimal levels postnatally. Nevertheless, neurogenic niches persist in the adult cortex and hippocampus in rodents, primates and humans, with adult NSC differentiation sharing key regulatory mechanisms with development. Adult neurogenesis impairments have been linked to Alzheimer's disease (AD) pathology.

Effect of Fenofibrate on Progression of Diabetic Retinopathy.

Background: Findings from cardiovascular outcome trials suggest that fenofibrate therapy may reduce the progression of diabetic retinopathy.

Methods: We recruited and followed adults with nonreferable diabetic retinopathy or maculopathy using the national Diabetic Eye Screening (DES) program in Scotland. We randomly assigned participants to receive 145-mg fenofibrate tablets or placebo (taken daily or, in those with impaired renal function, on alternate days).

Protocol for a systematic review and network meta-analysis of the use of prophylactic antibiotics in hand trauma surgery.

Background: The use of prophylactic antibiotics in surgery is contentious. With the rise in antimicrobial resistance, evidence-based antibiotic use should be followed. This systematic review and network meta-analysis will assess the effectiveness of different antibiotics on the prevention of surgical site infection (SSI) following hand trauma surgery.
