Descriptive Epidemiology of Complete ACL Tears in the Skeletally Immature Population: A Prospective Multicenter PLUTO Study.

Background: Anterior cruciate ligament (ACL) injuries are common in pediatric and adolescent patients. Understanding this population's injury characteristics and treatment strategies is vital for managing this high-risk group.

Purpose: To report the descriptive epidemiology and treatment strategies of a large cohort of skeletally immature patients with complete ACL tears.

Perspectives and experiences regarding pre-exposure prophylaxis (PrEP) in a community sample of Veterans with unhealthy alcohol use: overall and across sexual orientation and gender identity.

Background: Unhealthy alcohol use is an independent, modifiable risk factor for HIV, but limited research addresses alcohol use and HIV prevention synergistically. Groups that experience chronic stigma, discrimination, and/or other marginalization, such as sexual and gender minoritized groups, may have enhanced HIV risk related to unhealthy alcohol use. We described awareness of and experiences with pre-exposure prophylaxis (PrEP) among a community sample of Veterans reporting unhealthy alcohol use (relative to those without), overall and across self-reported sexual orientation and gender identity.

Species- and strain-specific microbial modulation of interferon, innate immunity, and epithelial barrier in 2D air-liquid interface respiratory epithelial cultures.

Background: The microbiome regulates the respiratory epithelium's immunomodulatory functions. To explore how the microbiome's biodiversity affects microbe-epithelial interactions, we screened 58 phylogenetically diverse microbes for their transcriptomic effect on human primary bronchial air-liquid interface (ALI) cell cultures.

Results: We found distinct species- and strain-level differences in host innate immunity and epithelial barrier response.

Effects of intra-class peer mentorship intervention programme on the academic performances of academically underperforming medical students in Nigeria.

Background: A significant gap exists in understanding the effectiveness of intra-class (same-class) level peer mentorship programmes designed to enhance academic performance, well-being, and student involvement among underperforming medical students. This study assessed the effectiveness of intra-class (same-class) peer mentorship programme on the academic performances, subjective well-being and school engagement of academically underperforming medical students in Nigeria.

Methods: This was a quasi-experimental research consisting of the pretest-posttest control design at Nnamdi Azikiwe University, Awka, Nigeria.

Ibuprofen reduces inflammation, necroptosis and protects photoreceptors from light-induced retinal degeneration.

Background: The retinal degenerative diseases retinitis pigmentosa (RP) and atrophic age- related macular degeneration (AMD) are characterized by vision loss from photoreceptor (PR) degeneration. Unfortunately, current treatments for these diseases are limited at best. Genetic and other preclinical evidence suggest a relationship between retinal degeneration and inflammation.

Association between metabolic score for visceral fat index and BMI-adjusted skeletal muscle mass index in American adults.

Background: The metabolic score for visceral fat (METS-VF) is a recently identified index for evaluating visceral fat, also referred to as abdominal obesity. The skeletal muscle mass index (SMI) serves as a critical measure for assessing muscle mass and sarcopenia. Both obesity and the reduction of muscle mass can significantly affect human health.

NLRX1 limits inflammatory neurodegeneration in the anterior visual pathway.

Chronic innate immune activation in the central nervous system (CNS) significantly contributes to neurodegeneration in progressive multiple sclerosis (MS). Using multiple experimental autoimmune encephalomyelitis (EAE) models, we discovered that NLRX1 protects neurons in the anterior visual pathway from inflammatory neurodegeneration. We quantified retinal ganglion cell (RGC) density and optic nerve axonal degeneration, gliosis, and T-cell infiltration in Nlrx1 and wild-type (WT) EAE mice and found increased RGC loss and axonal injury in Nlrx1 mice compared to WT mice in both active immunization EAE and spontaneous opticospinal encephalomyelitis (OSE) models.

Myricetin exposure reduces PC differentiation in vitro in primary human B cells.

Background: The process of B cell activation and plasma cell (PC) formation involves morphological, transcriptional, and metabolic changes in the B cell. Blocking or reducing PC differentiation is one approach to treat autoimmune diseases that are characterized by the presence of pathogenic autoantibodies. Recent studies have suggested the potential of myricetin, a natural flavonoid with anti-inflammatory and antioxidant properties, to block or reduce PC differentiation.

Lymphatic vessel network injury reduces local tumor control despite preservation of the tumor-draining lymph node.

The lymphatic system plays complex, often contradictory, roles in many cancers, including melanoma; these roles include contributions to tumor cell metastasis and immunosuppression in the tumor microenvironment as well as generation of antitumor immunity. Advancing our understanding of lymphatic vessel involvement in regulating tumor growth and immune response may provide new therapeutic targets or treatment plans to enhance the efficacy of existing therapies. We utilized a syngeneic murine melanoma model in which we surgically disrupted the lymphatic vessel network draining from the tumor to the tumor-draining lymph node (TDLN) while leaving the TDLN intact.

Noisy-channel language comprehension in aphasia: A Bayesian mixture modeling approach.

Individuals with "agrammatic" receptive aphasia have long been known to rely on semantic plausibility rather than syntactic cues when interpreting sentences. In contrast to early interpretations of this pattern as indicative of a deficit in syntactic knowledge, a recent proposal views agrammatic comprehension as a case of "noisy-channel" language processing with an increased expectation of noise in the input relative to healthy adults. Here, we investigate the nature of the noise model in aphasia and whether it is adapted to the statistics of the environment.

Readmissions and Mortality After "Before Medically Advised" Hospital Discharges Among Medicare Beneficiaries with Opioid Use Disorder.

Background: "Before medically advised" (BMA) discharges are rising among hospitalized people with opioid use disorder (OUD) and associated with worse outcomes. However, little is known about BMA discharge among the growing share of U.S.

Use of Antihyperglycemic Medications Among US People with Limited English Proficiency.

Background: Language barriers can impact pharmaceutical disease management leading to potential health disparities among limited English proficiency (LEP) people with diabetes mellitus (DM) in the United States (US).

Objective: To assess the use of antihyperglycemic medications and estimate their impact on glycemic control by LEP status.

Design: Cross-sectional design.

Sex-specific transcriptomic profiling reveals key players in bone loss associated with Alzheimer's disease.

Alzheimer's disease (AD), a progressive neurodegenerative disorder, is frequently associated with musculoskeletal complications, including sarcopenia and osteoporosis, which substantially impair patient quality of life. Despite these clinical observations, the molecular mechanisms linking AD to bone loss remain insufficiently explored. In this study, we examined the femoral bone microarchitecture and transcriptomic profiles of APP/PS1 transgenic mouse models of AD to elucidate the disease's impact on bone pathology and identify potential gene candidates associated with bone deterioration.

Nedosiran in pediatric patients with PH1 and relatively preserved kidney function, a phase 2 study (PHYOX8).

Background: Primary hyperoxaluria type 1 (PH1) is an autosomal recessive disorder with dysregulated glyoxylate metabolism in the liver. Oxalate over-production leads to renal stones, progressive kidney damage and renal failure, with potentially life-threatening systemic oxalosis. Nedosiran is a synthetic RNA interference therapy, designed to reduce hepatic lactate dehydrogenase (LDH) to decrease oxalate burden in PH.

Intestinal neutrophil extracellular traps promote gut barrier damage exacerbating endotoxaemia, systemic inflammation and progression of diabetic retinopathy in type 2 diabetes.

Aims/hypothesis: Within the small intestine, neutrophils play an integral role in preventing bacterial infection. Upon interaction with bacteria or bacteria-derived antigens, neutrophils initiate a multi-staged response of which the terminal stage is NETosis, formation of protease-decorated nuclear DNA into extracellular traps. NETosis has a great propensity to elicit ocular damage and has been associated with diabetic retinopathy and diabetic macular oedema (DME) progression.

Structural basis for human NKCC1 inhibition by loop diuretic drugs.

Na-K-Cl cotransporters functions as an anion importers, regulating trans-epithelial chloride secretion, cell volume, and renal salt reabsorption. Loop diuretics, including furosemide, bumetanide, and torsemide, antagonize both NKCC1 and NKCC2, and are first-line medicines for the treatment of edema and hypertension. NKCC1 activation by the molecular crowding sensing WNK kinases is critical if cells are to combat shrinkage during hypertonic stress; however, how phosphorylation accelerates NKCC1 ion transport remains unclear.

Infertility and risk of ovarian cancer in the women's health initiative.

Purpose: There is a consistent relationship with greater ovulation frequency and increased risk of ovarian cancer. However, prior research on infertility, which may be associated with ovulation frequency through multiple mechanisms, and ovarian cancer has yielded conflicting results, possibly due to prior research conflating fertility treatment with infertility and restricting follow-up to premenopausal cases. Our objective was to determine the association between infertility and risk of postmenopausal ovarian cancer, overall and by histotype, in a population that had not received treatment with IVF.

Description of STRIVE-ON Study Protocol: Safety and Tolerability of GTX-104 (Nimodipine Injection for IV Infusion) Compared with Oral Nimodipine in Patients Hospitalized for Aneurysmal Subarachnoid Hemorrhage (aSAH): A Prospective, Randomized, Phase III Trial (STRIVE-ON).

Oral nimodipine is the only drug approved in North America for patients with aneurysmal subarachnoid hemorrhage (aSAH). However, bioavailability is variable and frequently poor, leading to fluctuations in peak plasma concentrations that cause dose-limiting hypotension. Furthermore, administration is problematic in patients who cannot swallow.

Who drives weight stigma? A multinational exploration of clustering characteristics behind weight bias against preconception, pregnant, and postpartum women.

Background: Weight bias is a global health challenge and community members are endorsed as the most common source of weight bias. The nature of weight biases specifically against preconception, pregnant, and postpartum (PPP) women from the perspective of community members is not known, especially in terms of cross-cultural trends. We investigated the magnitude of explicit and implicit weight bias and profiles of characteristics associated with harbouring weight bias.

Mutant p53 regulates a distinct gene set by a mode of genome occupancy that is shared with wild type.

To directly examine the interplay between mutant p53 or Mdm2 and wild type p53 in gene occupancy and expression, an integrated RNA-seq and ChIP-seq analysis was performed in vivo using isogenically matched mouse strains. Response to radiation was used as an endpoint to place findings in a biologically relevant context. Unexpectedly, mutant p53 and Mdm2 only inhibit a subset of wild type p53-mediated gene expression.

Association of oxidative balance score with the risk of all-cause and CVD mortality in younger US adults with diabetes.

Oxidative balance score (OBS) is a composite measures that assess the balance between pro-oxidant and antioxidant factors in an individual's diet and lifestyle, with higher scores indicating greater antioxidant exposure. Despite its potential significance, there is a limited body of research exploring the relationship between OBS and all-cause and cardiovascular disease (CVD) mortality specifically in younger patients with diabetes. We aimed to investigate the possible relationship between OBS and all-cause and CVD mortality in younger patients with diabetes.

Leveraging synthetic data to improve regional sea level predictions.

The rapid increase in sea levels driven by climate change presents serious risks to coastal communities around the globe. Traditional prediction models frequently concentrate on developed regions with extensive tide gauge networks, leaving a significant gap in data and forecasts for developing countries where the tide gauges are sparse. This study presents a novel deep learning approach that combines TimesGAN with ConvLSTM to enhance regional sea level predictions using the more widely available satellite altimetry data.

Argonaute2 modulates megakaryocyte development and sex-specific control of platelet protein expression and reactivity.

Platelets are enriched in miRNAs and harbor Ago2 as the principal RNA silencing Argonaute. However, roles in thrombopoiesis and platelet function remain poorly understood. We generated megakaryocyte/platelet-specific Ago2-deleted (Ago2 KO) mice and assessed proteomic and functional effects.

Large language models improve the identification of emergency department visits for symptomatic kidney stones.

Recent advancements of large language models (LLMs) like generative pre-trained transformer 4 (GPT-4) have generated significant interest among the scientific community. Yet, the potential of these models to be utilized in clinical settings remains largely unexplored. In this study, we investigated the abilities of multiple LLMs and traditional machine learning models to analyze emergency department (ED) reports and determine if the corresponding visits were due to symptomatic kidney stones.
