Adolescence is a vulnerable period for the onset of mental disorders and risk behaviours. Based on the Health-Promoting Schools Framework, whole-school interventions offer a promising strategy in this developmentally-sensitive cohort, through championing a systems-based approach to promotion and prevention that involves the key stakeholders in an adolescent's life. The evidence-base surrounding the effectiveness of whole-school interventions, however, remains inconclusive, partly due to the insufficient number of studies in previous meta-analyses.

Left neck and right biceps muscle vibrations have similar effects on perceived body orientation.

Exp Brain Res

January 2025

Center of Neurology, Division of Neuropsychology, Hertie-Institute for Clinical Brain Research, University of Tübingen, Tübingen, Germany.

Vibrating muscles to manipulate proprioceptive input creates the sensation of an apparent change in body position. This study investigates whether vibrating the right biceps muscle has similar effects as vibrating the left posterior neck muscles. Based on previous observations, we hypothesized that both types of muscle vibration would shift the perception of healthy subjects' subjective straight-ahead (SSA) orientation in the horizontal plane to the left.

"It's Like You're Feeding Your Child Twice": Barriers and Facilitators to Human Milk Feeding Children With Cystic Fibrosis.

Pediatr Pulmonol

January 2025

Department of Pediatrics, Division of Pulmonary, Allergy/Immunology, Cystic Fibrosis and Sleep, Emory University, Atlanta, Georgia, USA.

Background: Cystic Fibrosis Foundation guidelines recommend human milk (HM) as the ideal source of nutrition for children with CF (cwCF). Despite known pulmonary and nutritional benefits, fewer cwCF ever receive HM compared to the general population. Early nutrition choices are preference-sensitive, yet little is known about the factors that impede or sustain HM feeding among parents of cwCF.

Tumor-infiltrating lymphocytes (TILs) are a protective prognostic factor in several solid tumors and predict response to immune checkpoint inhibitor therapy. The prognostic impact of TILs in medullary thyroid cancer (MTC) is poorly understood. In this retrospective cohort study, we assessed the TILs profile of primary MTC tumors using the International TILs Working Group system and correlated this with clinicopathological prognostic variables, including the International Medullary Thyroid Cancer Grading System (IMTCGS) grade and survival outcomes.

January 2025

Graduate Institute of Biomedical Materials and Tissue Engineering, College of Biomedical Engineering, Taipei Medical University, 6F Biomedical Technology Building, No. 301, Yuantong Rd., Zhonghe Dist., New Taipei City, 23564, Taiwan.

Background And Objective: Osteoarthritis is a widespread and debilitating condition, particularly affecting the medial compartment of knee joint due to varus knee deformities. Medial opening wedge high tibial osteotomy (MOWHTO) has emerged as an effective treatment, but it comes with challenges like fractures, correction loss, and nonunion, leading to unsatisfactory results in up to 26 % of patients. In response, our study explores the potential of a bioabsorbable magnesium-based bulk metallic glass composite (MgZnCa BMGC) enriched with molybdenum particles as an innovative solution for MOWHTO.
