The effect of pregnancy vitamin D supplementation on maternal blood pressure: real-world data analysis within the MAVIDOS randomised placebo-controlled trial.

Purpose: Observational studies have suggested negative associations between maternal 25-hydroxyvitamin D (25(OH)D) status and risk of hypertensive disorders of pregnancy [pregnancy-induced hypertension (PIH) and preeclampsia (PET)]. Data from intervention studies are limited. We hypothesised that vitamin D supplementation would lower maternal blood pressure (BP) during pregnancy and reduce the incidence of hypertensive disorders of pregnancy.

Trends and predictors of reporting social determinants of health in shoulder surgery.

Background: The role of social determinants of health (SDH) in patient outcomes, quality of life, and overall well-being has been well documented. However, the inclusion of these variables in randomized control trials (RCTs) remains limited; thus, the extent of generalizability from such trials is brought into question. The purpose of this study is to explore the rates of reporting SDH variables in RCTs focused on shoulder surgery from the past decade.

Defining the Cost of Arthroscopic Rotator Cuff Repair: A Multicenter, Time-Driven Activity-Based Costing and Cost Optimization Investigation.

Background: Rotator cuff repair (RCR) is a frequently performed outpatient orthopaedic surgery, with substantial financial implications for health-care systems. Time-driven activity-based costing (TDABC) is a method for nuanced cost analysis and is a valuable tool for strategic health-care decision-making. The aim of this study was to apply the TDABC methodology to RCR procedures to identify specific avenues to optimize cost-efficiency within the health-care system in 2 critical areas: (1) the reduction of variability in the episode duration, and (2) the standardization of suture anchor acquisition costs.

A Prospective Observational Cohort Study Comparing High-Complexity Against Conventional Pelvic Exenteration Surgery.

Conventional pelvic exenteration (PE) comprises the removal of all or most central pelvic organs and is established in clinical practise. Previously, tumours involving bone or lateral sidewall structures were deemed inoperable due to associated morbidity, mortality, and poor oncological outcomes. Recently however high-complexity PE is increasingly described and is defined as encompassing conventional PE with the additional resection of bone or pelvic sidewall structures.

Effect of diabetes and hyperglycaemia on the physical and mechanical properties of dentine: a systematic review.

Objectives: The aim of this systematic review was to assess the effect of DM (Type 1 and Type 2 Diabetes) and hyperglycaemia on the physical and mechanical properties of dentine which is critical for successful endodontic treatment.

Method: An electronic search of the following databases: PubMed, MEDLINE, Web of Science and the grey literature was performed up until July 2024. In vitro and in vivo studies on the effect of DM or hyperglycaemia on the mechanical and physical properties of dentine were included.

Osteoid Osteoma in an Elderly Patient: Diagnostic Challenges.

Osteoid osteoma is a benign bone tumor commonly affecting young individuals, with a rare occurrence in older adults. It typically presents with night pain relieved by nonsteroidal anti-inflammatory drugs and is characterized radiographically by a small, radiolucent nidus surrounded by reactive sclerosis. We present a 70-year-old female patient with persistent right hip pain, initially diagnosed as arthritis, who underwent total hip arthroplasty.

Induction of Epithelial-Mesenchymal Transition in Periodontitis Rat Model.

Objectives:  Epithelial-mesenchymal transition (EMT) is a process that shifts cellular phenotype. It is linked to several different inflammatory diseases including periodontitis. This study was conducted to investigate the involvement of the EMT process in an experimental periodontitis (EP) model.

Long-Term Outcomes of Acute Temporal Bone Fractures.

Objective(s): To compare the incidence of acute and chronic complications of temporal bone fractures, and identify predictors for post-injury, audiometrically confirmed hearing loss.

Methods: Retrospective cohort analysis of patients with acute temporal bone fractures who underwent both in-hospital and outpatient follow-up Otolaryngology evaluation at an academic, tertiary-care institution from January 2002 to January 2023. Otologic outcomes were compared between initial and follow-up evaluations.

Impact of dementia and mild cognitive impairment on bone health in older people.

Mild cognitive impairment, dementia and osteoporosis are common diseases of ageing and, with the increasingly ageing global population, are increasing in prevalence. These conditions are closely associated, with shared risk factors, common underlying biological mechanisms and potential direct causal pathways. In this review, the epidemiological and mechanistic links between mild cognitive impairment, dementia and skeletal health are explored.

Inborn errors of immunity reveal molecular requirements for generation and maintenance of human CD4 IL-9-expressing cells.

Background: CD4 T cells play essential roles in adaptive immunity. Distinct CD4 T-cell subsets-T1, T2, T17, T22, T follicular helper, and regulatory T cells-have been identified, and their contributions to host defense and immune regulation are increasingly well defined. IL-9-producing T9 cells were first described in 2008 and appear to play both protective and pathogenic roles in human immunity.

NF-κB c-Rel is a critical regulator of TLR7-induced inflammation in psoriasis.

Background: Nuclear factor kappa B (NF-κB) c-Rel is a psoriasis susceptibility locus, however mechanisms underlying c-Rel transactivation during disease are poorly understood. Inflammation in psoriasis can be triggered following Toll-like Receptor 7 (TLR7) signalling in dendritic cells (DCs), and c-Rel is a critical regulator of DC function. Here, we studied the mechanism of TLR7-induced c-Rel-mediated inflammation in DCs.

Genome-wide meta-analysis conducted in three large biobanks expands the genetic landscape of lumbar disc herniations.

Given that lumbar disc herniation (LDH) is a prevalent spinal condition that causes significant individual suffering and societal costs, the genetic basis of LDH has received relatively little research. Our aim is to increase understanding of the genetic factors influencing LDH. We perform a genome-wide association analysis (GWAS) of LDH in the FinnGen project and in Estonian and UK biobanks, followed by a genome-wide meta-analysis to combine the results.

Guided Growth for Correction of Elevated Tibial Posterior Slope in Pediatric ACL Deficiency: A Case Report.

Case: Fourteen-year-old boy, history of autism presented with bilateral knee instability. Imaging revealed bilateral anterior cruciate ligament (ACL) insufficiency, 20° of posterior tibial slope (PTS) on the right and 18° on the left. A guided growth technique using anterior placed tension band plates was used to correct the PTS.

Surgical Predictors of Clinical Outcome 6 Years After Revision ACL Reconstruction.

Background: Revision anterior cruciate ligament (ACL) reconstruction has been documented to have inferior outcomes compared with primary ACL reconstruction. The reasons why remain unknown.

Purpose: To determine whether surgical factors performed at the time of revision ACL reconstruction can influence a patient's outcome at 6-year follow-up.

Functionality of lyophilized osteoinductive EVs: a mechanistic study.

Introduction: Mesenchymal stem cell-derived extracellular vesicles (MSC EVs) hold significant promise for regenerative medicine. Lyophilization of EVs significantly enhances their translational potential. While, lyophilized EVs have been studied from a morphological perspective, the functional stability of these EVs and their cargo following lyophilization need to be mechanistically investigated.

An Efficiency Model for Decreasing Operative Room Turnover Time for Total Joint Arthroplasties.

Objectives: Despite an increased demand for total joint arthroplasty (TJA), rising health-care costs and bundling of payments by payers have shifted the focus to improving operating room (OR) efficiency. This study aimed to assess the efficacy of an efficiency model that optimized instrument trays on decreasing OR turnover time (TOT) and the benefits made possible by this improved efficiency.

Methods: All primary TJA procedures performed by a single fellowship-trained surgeon from January 2022 to August 2023 were reviewed.

Association Between MRI Findings of Facet Arthropathy and Synovitis With Health-Related Outcome and Pain Scores Following Therapeutic Lumbar Facet Injections.

Low back pain is a common complaint among adults. The facet joint is a major source of lumbar pain, and therapeutic facet injections have gained popularity as a minimally invasive treatment option. In addition, magnetic resonance imaging (MRI) utilization for diagnosing low back pain has increased significantly over the past few decades.

The COVID-19 Pandemic's Effect on Preventive Imaging.

Introduction: This study assessed the effect of the COVID-19 pandemic on preventive care imaging and potential disparities because preventive care may be perceived as nonurgent. The objective was to identify the associations between the COVID-19 pandemic and changes in preventive imaging volumes for patients in general and as affected by race and ethnicities.

Methods: The authors performed a retrospective observational study by extracting the weekly volumes of all imaging studies between January 7, 2019 and May 1, 2022 from a radiology data warehouse at a tertiary care medical center (=92,105 preventive imaging studies and 3,493,063 total radiology imaging studies) and compared preshutdown with postshutdown periods using a 2-sample -test.

Investigating the long-term outcomes and efficacy of surgical intervention in patients with adolescent idiopathic scoliosis and Cobb angles ranging between 40 and 50 degrees.

Purpose: Patients with adolescent idiopathic scoliosis (AIS) are either managed with non-operative strategies or surgery depending on the severity of lateral curvature and impact on quality of life. However, supportive evidence for the appropriate treatment approach is lacking in AIS patients with Cobb angles between 40 and 50 degrees. Therefore, we investigated differences in long-term patient-centered outcomes in AIS patients with Cobb angles between 40 and 50 degrees who received either operative or non-operative management.
