Enhancing Recovery in Severe Adolescent Idiopathic Scoliosis (AIS) Patients With Cobb Angle ≥90 Degrees Undergoing Single-staged Posterior Spinal Fusion (PSF): Evaluating the Feasibility of Rapid Recovery Protocol (RRP).

Study Design: Retrospective study.

Objective: To assess the feasibility and outcome of rapid recovery protocol (RRP) in severe adolescent idiopathic scoliosis (AIS) patients with Cobb angle ≥90 degrees underwent single-staged posterior spinal fusion (PSF).

Summary Of Background Data: Corrective surgeries in severe AIS patients entail a higher risk of prolonged operation, excessive bleeding, extended hospital stay, and higher complication rates compared with non-severe AIS patients.

A mathematical model for estimating the intraoperative lowest instrumented vertebra (LIV) tilt angle using preoperative supine left side-bending (LSB) radiographs in adolescent idiopathic scoliosis (AIS) patients with lenke type 1 and 2 non-AR curves.

Purpose: To devise a mathematical model for estimating the intraoperative lowest instrumented vertebra (LIV) tilt angle using preoperative supine left side-bending (LSB) radiographs in adolescent idiopathic scoliosis (AIS) patients with Lenke type 1 and 2 (non-AR curves), and to review its clinical and radiological outcomes.

Methods: The mathematical model for the adjusted LSB LIV tilt angle (α) measured preoperatively, was expressed as the sum of preoperative LSB LIV tilt angle (x) and LIV displacement angle (y) (α = x + y). This model was validated through inter-rater and intra-rater analysis in Part I of the study.

Physical activity and incident cardiovascular disease in breast cancer survivors: the pathways study.

Purpose: Breast cancer survivors experience higher rates of cardiovascular disease (CVD) than women without breast cancer, due in part to cardiotoxic cancer treatments and shared lifestyle risk factors. Physical activity is associated with lower mortality risk in breast cancer survivors, but associations with CVD have not been examined in detail.

Methods: The Pathways Study is a prospective cohort study of 4,504 women diagnosed with invasive breast cancer between 2005 and 2013.

Development and validation of the Post-COVID Symptom Scale for Children/Youth (PCSS-C/Y).

This study aims to develop and validate the Post-COVID Symptom Scale for Children/Youth (PCSS-C/Y), which is a comprehensive tool for measuring the symptom burden of post-COVID-19 conditions-persistent symptoms after SARS-CoV-2 infection, commonly known as Long COVID-and its impact on health-related quality of life among children and adolescents. Parents of children and adolescents, adolescents, and young adults with and without a history of COVID-19 were invited to fill in a questionnaire from October 2022 to June 2023. There were 386 valid parent proxy-reported responses, 433 valid adolescent self-reported responses, and 324 valid young adult self-reported responses included in the final analysis.

Machine learning derived physical activity in preschool children with developmental coordination disorder.

Aim: To compare the device-measured physical activity behaviours of preschool children with typical motor development to those with probable developmental coordination disorder (pDCD) and at risk for developmental coordination disorder (DCDr).

Method: A total of 497 preschool children (4-5 years) in the Coordination and Activity Tracking in CHildren (CATCH) study completed repeated motor assessments and wore an ActiGraph GT3X on the right hip at baseline for 1 week. We calculated physical activity metrics from raw accelerometer data using a validated random forest classification machine learning model for preschool-age children.
