Basic Science and Pathogenesis.

Background: Alzheimer's disease disproportionately affects women in the U.S., with two-thirds of individuals diagnosed being female.

Basic Science and Pathogenesis.

Background: Alzheimer's disease (AD) pathology can start accumulating 20-30 years before cognitive symptoms occur, with increases in inflammation, amyloid-β (Aβ), and hyperphosphorylated Tau during this time. Previous studies have shown that the post-translational modification of a single N-acetylglucosamine moiety to serine or threonine residues to cytosolic or nuclear proteins, known as O-GlcNAcylation, can modify a plethora of cellular processes, including the processing of the amyloid precursor protein, competing with phosphorylation on tau, as well as having anti-inflammatory effects. This study is designed to evaluate how increasing O-GlcNAcylation is impacting AD pathology in the most comprehensive AD rat model to date, the TgF344-AD rat model.

Characteristics and Guardianship Status of Children Undergoing Forensic Medical and Psychological Evaluation for Asylum in Miami.

To add to the limited evidence on forensic medical and psychological evaluations of children experiencing distress migration and seeking asylum in the United States, this paper describes the sociodemographic characteristics, nature of human rights violations, and guardianship status of the children served by the Human Rights Clinic of Miami from 2010 to 2021. Through a retrospective study of affidavits, we identified trends among sociodemographic characteristics and types of human rights violations and used bivariate analysis to determine factors associated with guardianship. Children constituted 17% of all evaluations conducted during this period.

Factors Associated With Increased Sex Diversity in Orthopaedic Trauma Association-Accredited Fellowship Training.

Introduction: This study quantifies the state of sex diversity in orthopaedic trauma training and analyzes fellowship program characteristics associated with greater sex diversity among trainees. We hypothesized that greater sex diversity among orthopaedic trauma fellows would be associated with the presence of female faculty.

Methods: This was a retrospective, cross-sectional study of orthopaedic trauma faculty (2023 to 2024) and fellows (2009 to 2024).

Hemodynamic markers independent of pulmonary capillary wedge pressure can discriminate between pre and postcapillary exercise-induced pulmonary hypertension.

The discrimination between pre and postcapillary exercise-induced pulmonary hypertension relies on accurate measurement of pulmonary capillary wedge pressure, which can be unreliable. We found that exercise pulmonary artery compliance and right atrial pressure (AUC 0.88, 0.

Nature and Magnitude of Industry Payments to Fellowship Program Directors in Orthopaedic Surgery.

Introduction: Previous research has highlighted conflicts of interest stemming from industry funding and education of orthopaedic surgeons. This study sought to define the nature and magnitude of industry payments to orthopaedic surgery fellowship program directors (FPDs) in the United States.

Methods: This was a retrospective cohort study of orthopaedic surgery FPDs during 2021.

Effect of sintering cycle on the strength and translucency of multilayered zirconia.

Purpose: A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated. The purpose of this study was to measure and compare the effect of two sintering protocols on the translucency and flexural strength of two multilayered zirconia materials.

Between-limb difference in peak knee flexion angle can identify persons post-stroke with Stiff-Knee gait.

Background: Stiff-Knee gait affects 25-75 % of individuals with post-stroke gait impairment and is typically defined as reduced swing phase knee flexion. Different studies use various measures to identify Stiff-Knee gait, such as peak swing knee flexion angle, timing of peak knee flexion, knee range of motion, and ankle push-off acceleration, leading to inconsistent results.

Methods: This study used univariate cluster analysis to examine the independence, consistency, validity, and accuracy of different definitions in 50 post-stroke individuals (24 with and 26 without Stiff-Knee gait), as determined by a physiatrist.

Trends in Case Volume Reported by Musculoskeletal Oncology Fellows in Accreditation Council for Graduate Medical Education-Accredited Training Programs: 2017 to 2022.

Introduction: Increasingly, national accrediting bodies and professional societies for musculoskeletal oncology recognize the need for more standardized training. This study elucidates recent trends in reported case volume during Accreditation Council for Graduate Medical Education (ACGME)-accredited musculoskeletal oncology fellowship training relative to case minimum requirements.

Methods: We conducted a retrospective cross-sectional analysis of fellows at ACGME-accredited musculoskeletal oncology fellowships (2017 to 2022).

Implementing a Peer Support Program for Second Victims.

The second victim phenomenon describes the distress frequently experienced by health care providers after an unintentional medical error or unexpected adverse event. However, few health care institutions have initiatives that proactively address this phenomenon. The pilot project discussed in this article aimed to create a peer support program for health care providers experiencing the second victim phenomenon.

Vitamin D Supplementation May Prevent or Treat Deficiency After Total Knee Arthroplasty: A Retrospective Cohort Analysis.

Background: Vitamin D deficiency is associated with poorer functional outcomes and increased complication rates after total knee arthroplasty (TKA). Yet, there is no longer term study evaluating vitamin D levels and supplementation after TKA. Our study aimed to compare quantitative vitamin D levels and supplementation regimens after TKA stratified by patient sex and race.

Islet Isolation Outcomes in Patients Undergoing Total Pancreatectomy With Islet Autotransplantation in the POST Consortium.

Background: In total pancreatectomy with islet autotransplantation (TPIAT), a greater number of islets transplanted produces more favorable outcomes. We aimed to determine predictors of islet isolation outcomes.

Methods: We investigated factors associated with islet isolation outcomes expressed as islet number (IN), islet equivalents (IEQ; standardized to an islet with 150 μm diameter), IN/kg, or IEQ/kg using data from the multicenter Prospective Observational Study of TPIAT.

Intraoperative Adjuncts in Thyroid Surgery.

Thyroidectomy is relatively safe and often can be done as a minimally invasive procedure. Although they may be associated with a learning curve, thoughtful use of intraoperative adjuncts such as energy devices, recurrent laryngeal nerve monitoring, and parathyroid autofluorescence have the potential to make incremental improvements in the safety and efficiency of thyroid surgery. Perhaps many of these adjuncts may be of greatest benefit when used routinely by less experienced surgeons or selectively in higher-risk operations, although their adoption in practice continues to increase overall.
