Article Abstract
Purpose: The purpose of this study is to characterize the effect of sex and the influence of oral contraception usage on musculotendinous injury (MTI). Current literature suggests a disparity in the incidence of MTI between males and females. This may be attributed to inherent biological differences between the sexes, such as in the sex hormonal milieu. There is a lack of information associating sex hormone milieu and MTI.
Methods: We searched the PearlDiver database (a for-fee healthcare database) for males, females taking oral contraceptives (OC), and eumenorrheic females not taking any form of hormonal contraceptives (non-OC) 18-39 yr old. The three populations were matched by age and body mass index. We queried the database for lower-extremity skeletal MTI diagnoses in these groups.
Results: Each group contained 42,267 patients with orthopedic injuries. There were a total of 1476 (3.49%) skeletal MTI in the male group, 1078 (2.55%) in non-OC females, and 231 (0.55%) in OC females. Both the non-OC and the OC groups had a significantly smaller proportion of MTI than males ( P < 0.0001), and therefore these groups were less likely (adjusted odds ratios, 0.72 and 0.15, respectively) to experience MTI when controlled for potential covariates.
Conclusions: In this study, we show that females are less likely to develop MTI to total injuries, when compared with males, with OC using females being least likely followed by non-OC females. These results are consistent with other epidemiological studies; however, overall results in the literature are variable. This study adds to the emerging body of literature on sex hormone-influenced musculoskeletal injury but, more specifically, MTI, which have not been rigorously investigated.

NAD Metabolism Regulates Proliferation of Macrophages in Atherosclerosis.
Arterioscler Thromb Vasc Biol
September 2025
Department of Medicine/Division of Cardiology, University of California Los Angeles. (S.S., C.R.S., L.F., M.P., C.P., Z.Z., J.J.M., R.C.D., D.S., A.J.L.).
Background: In genetic studies with the Hybrid Mouse Diversity Panel, we previously identified a chromosome 9 locus for atherosclerosis. We now identify NNMT (nicotinamide -methyltransferase), an enzyme that degrades nicotinamide, as the causal gene in the locus and show that the underlying mechanism involves salvage of nicotinamide to nicotinamide adenine dinucleotide (NAD).
Methods: Gain/loss of function studies in macrophages were performed to examine the role of NAD levels in macrophage proliferation and apoptosis in atherosclerosis.
Antibiotic Therapy for Pyelonephritis in the Emergency Department.

Objectives: Acute pyelonephritis (APN) is a common diagnosis among patients presenting to the Emergency Department (ED). It is treated by empiric antibiotics within the ED. With a rise in antimicrobial resistance globally, it is unknown whether patients are being managed with empiric antibiotics that are appropriate for the causative organisms of APN.

Reliably defining the risk of adverse in-flight events in aeromedical trauma patients could enable more informed pre-departure treatment and guide central asset allocation to achieve better system-level outcomes. Unfortunately, the current literature base specifically examining the in-flight period is sparse. Flight duration is often considered a proxy for the risk of in-flight deterioration; however, there is limited data to support this commonly held assumption.

Objective: This study applied the Theoretical Domains Framework (TDF) to explore the barriers and enablers to optimizing post-operative pain management and supporting safe opioid use from the perspectives of both patients and health care professionals, applying the Theoretical Domains Framework (TDF).
Design: Experience-based co-design (EBCD) qualitative study.
Methods: In the initial phase of the EBCD approach, focus groups were conducted comprising 20 participants, including 8 patients and 12 health care professionals involved in post-operative care.
Sex distribution in tuberculosis disease in children, adolescents, and adults in a low-incidence country: a retrospective population-based cohort study.

Mycobacterial and Migrant Health Research Group, University of Basel Children's Hospital Basel and Department of Clinical Research, University of Basel, Basel, Switzerland.
Aim: Globally, tuberculosis incidence shows notable sex disparity, with higher rates observed in males. While this pattern is well documented in adults from high-incidence countries, the influence of sex on tuberculosis incidence in children and adolescents, particularly in low-incidence settings, remains unclear. This study investigated sex-specific tuberculosis incidence rates across all age groups, focusing on adolescents, in a low-incidence country.
