To determine if volleyball (VB), basketball (BB), soccer (SO) and swimming (SW) programs were associated with site-specific differences in contralateral, regional, and total body bone mineral density (BMD), 62 eumenorrheic female athletes [BB (N = 7), VB (N = 11), SO (N = 9), and SW (N = 7)] and controls participated in the study. The controls were categorized as either moderately active control (MOD) (N = 17) or sedentary control (SED) (N = 11) based on fitness and activity assessments. Contralateral, total body, lumbar (L2-L4), and femur BMD were measured (Lunar DPX). The between sport contralateral comparisons indicated that VB and BB had significantly greater leg and arm measurements than all other groups, while the within contralateral comparisons revealed significantly greater right arm measurements for all groups, except SW. No significant differences were found for the within group contralateral leg comparisons, except VB. VB and BB had significantly higher (P < or = 0.05) total body and lumbar BMD values than SW, MOD, and SED. At the femur neck, trochanter, and Ward's triangle, BB showed significantly higher BMD than SW, MOD, and SED. Only BB had significantly higher Ward's triangle BMD than SW, MOD, and SED. Our findings show site-specific differences in BMD associated with selected sports' programs.

Loneliness is associated with different structural brain changes in schizophrenia spectrum disorders and major depression.
Schizophr Res
January 2025
Department of Psychiatry and Psychotherapy, Central Institute of Mental Health, Medical Faculty Mannheim, Heidelberg University, Mannheim, Germany; German Center for Mental Health (DZPG), partner site Mannheim-Heidelberg-Ulm, Germany. Electronic address:
Background: Loneliness, distress from having fewer social contacts than desired, has been recognized as a significant public health crisis. Although a substantial body of research has established connections between loneliness and various forms of psychopathology, our understanding of the neural underpinnings of loneliness in schizophrenia spectrum disorders (SSD) and major depressive disorder (MDD) remains limited.
Methods: In this study, structural magnetic resonance imaging (sMRI) data were collected from 57 SSD and 45 MDD patients as well as 41 healthy controls (HC).
Decreased Association Between Patellar Axial Malalignment and Patellar Height and Increased Association Between Patellar Axial Malalignment and Tibial Tubercle-Trochlear Groove During Weightbearing.
Clin Orthop Relat Res
January 2025
Department of Radiology, Chongqing Health Center for Women and Children/Women and Children's Hospital of Chongqing Medical University, Chongqing, PR China.
Background: Nonweightbearing preoperative assessments avoid quadriceps contraction that tends to affect patellar motion and appear to be inaccurate in quantifying anatomic factors, which can lead to incorrect corrections and postoperative complications.
Questions/purposes: (1) Does the relationship of patellar axial malalignment and other anatomic factors change during weightbearing? (2) What anatomic factor was most strongly correlated with recurrent patellar dislocation during weightbearing?
Methods: This prospective, comparative, observational study recruited participants at our institution between January 2023 and September 2023. During this time, all patients with recurrent patellar dislocations received both weightbearing and nonweightbearing CT scans; control patients who received unilateral CT scans because of injuries or benign tumors received both weightbearing and nonweightbearing CT scans.
Intraoperative Tranexamic Acid Infusion Reduces Perioperative Blood Loss in Pediatric Limb-Salvage Surgeries: A Double-Blinded Randomized Placebo-Controlled Trial.
J Bone Joint Surg Am
January 2025
National Cancer Institute, Cairo University, Giza, Egypt.
Background: Limb-salvage surgery for malignant bone tumors can be associated with considerable perioperative blood loss. The aim of this randomized controlled trial was to assess the safety and efficacy of the intraoperative infusion of tranexamic acid (TXA) in children and adolescents undergoing limb-salvage surgery.
Methods: All participants were <18 years of age at the time of surgery and diagnosed with a malignant bone tumor of the femur that was treated with resection and reconstruction with a megaprosthesis.
Influence of Insertion/Deletion Polymorphism of the Angiotensin Converting Enzyme Gene on Adiposity and Cardiac Function in Patients with Heart Failure.
Arq Bras Cardiol
January 2025
Programa de Pós-Graduação em Alimentação, Nutrição e Saúde - Universidade Federal do Rio Grande do Sul, Porto Alegre, RS - Brasil.
Background: The angiotensin-converting enzyme (ACE) insertion/deletion (I/D) polymorphism (rs4340) is associated with the pathogenesis of heart failure (HF). This polymorphism may contribute to a greater propensity for severe HF and excess weight.
Objective: To evaluate adiposity, cardiac function, and their association with ACE I/D polymorphism in HF patients.
Metabolic dysfunction-associated liver disease and biliary lithiasis in children with Down Syndrome: a retrospective study.
Rev Paul Pediatr
January 2025
Universidade Federal do Paraná, Curitiba, PR, Brazil.
Objective: To investigate the presence of metabolic dysfunction-associated fatty liver disease (MAFLD) and gallbladder abnormalities in a sample of people with Down syndrome in Brazil.
Methods: This is a retrospective study using medical charts involving Down syndrome patients, diagnosed by karyotype, aged over 5 years, who underwent abdominal ultrasound and were monitored by the same professional in a clinic in Curitiba, Brazil. Data spanned January 1995 to September 2023; all cases with no use of alcohol or hepatotoxic medications.
