Objective: This study aims to analyse changes in body sway over the course of pregnancy.
Study Design: This is a descriptive study in which stabilometric tests were applied at three stages of pregnancy and with a combination of different visual conditions (eyes open/closed) and support base configuration (feet together/apart). Twenty healthy pregnant women participated in the study. Changes in postural control with pregnancy were analysed via the elliptical area of the stabilograms and spectral analysis of the displacements of the centre of pressure (COP) along the lateral and anterior/posterior directions.
Results: The elliptical area encompassing the COP significantly increased over the course of the pregnancy for the feet apart and eyes closed test protocols. The spectral analysis revealed a significant increase of COP oscillations along the anterior-posterior direction when subjects stood with the eyes open/feet together and feet apart. A reduction (significant) of the lateral oscillations of COP was observed for the eyes open/feet together protocol.
Conclusion: Pregnancy induced significant changes in the postural control when pregnant women stood with a reduced support base or with eyes closed.

No Association Between Donor Variables and Clinically Significant Outcomes, Reoperations, and Failure After Osteochondral Allograft Transplantation.

Background: Mismatch between osteochondral allograft (OCA) donor and recipient sex has been shown to negatively affect outcomes. This study accounts for additional donor variables and clinically relevant outcomes.
Purpose: To evaluate whether donor sex, age, donor-recipient sex mismatch, and duration of graft storage affect clinical outcomes and failure rates after knee OCA transplantation.
Experiences of perinatal genetic screening for people from migrant and refugee backgrounds: a scoping review.

People from refugee and migrant backgrounds often face poor experiences and outcomes in healthcare, and genetic healthcare is no exception. Understanding whether and how these health inequities manifest is an important step towards equitable perinatal genetic screening for genetic or chromosomal conditions (offered preconception, prenatally, or during the newborn period). A scoping review was conducted to review international evidence of perceptions and experiences of perinatal genetic screening for people from migrant and refugee backgrounds.

Objectives: This paper aims to review the immunopathogenesis of Diabetes-associated periodontitis (DPD) and to propose a description of the research progress of drugs with potential clinical value from an immunotherapeutic perspective.
Materials And Methods: A comprehensive literature search was conducted in PubMed, MEDLINE, Embase, Web of Science, Scopus and the Cochrane Library. Inclusion criteria were studies on the association between diabetes and periodontitis using the Boolean operator "AND" for association between diabetes and periodontitis, with no time or language restrictions.
Emergency department ophthalmoscopy: physician confidence and clinical practices.
CJEM
January 2025
Department of Ophthalmology and Vision Sciences, University of Toronto, Toronto, ON, Canada.
Objectives: Fundoscopy is crucial in the emergency department to identify or rule out serious ocular and neurological conditions. Despite its clinical importance, fundoscopy is often omitted due to the technical challenges associated with traditional direct ophthalmoscopy, particularly for non-ophthalmologists. This study examines emergency physicians' practices, confidence levels, and training related to various modalities of fundoscopy including traditional direct ophthalmoscopes, binocular indirect ophthalmoscopes, panoptic ophthalmoscopes, slit lamp fundoscopy and fundus cameras; and explores the potential role of alternative modalities, such as fundus cameras, in Canadian emergency departments.

Streptococcus pneumoniae (SP) remains an important cause of community acquired pneumonia (CAP). We aimed to describe the prevalence and characteristics of outpatients with radiologically confirmed pneumococcal CAP. Between November 2017 and December 2019, a French network of general practitioners enrolled CAP-suspected adults, with ≥1 clinical signs of infection and ≥1 signs of pulmonary localization in an observational study.
