Background And Purpose: We examined differences in the volume and pattern of physical activity (PA) and sedentary behavior between adults with and without stroke.
Methods: We studied cohort members with an adjudicated or self-reported stroke (n=401) and age-, sex-, race-, region of residence-, and body mass index-matched participants without a history of stroke (n=1203) from the REGARDS study (Reasons for Geographic and Racial Differences in Stroke). Sedentary behavior (total volume and bouts), light-intensity PA, and moderate-to-vigorous-intensity PA were objectively measured for 7 days via hip-worn accelerometer.
Results: Sedentary time (790.5±80.4 versus 752.4±81.9 min/d) and mean sedentary bout duration (15.7±12.6 versus 11.9±8.1 min/d) were higher and PA (light-intensity PA: 160.5±74.6 versus 192.9±73.5 min/d and moderate-to-vigorous-intensity PA: 9.0±11.9 versus 14.7±17.0 min/d) lower for stroke survivors compared with controls (P<0.001). Stroke survivors also accrued fewer activity breaks (65.5±21.9 versus 73.31±18.9 breaks/d) that were shorter (2.4±0.7 versus 2.7±0.8 minutes) and lower in intensity (188.4±60.8 versus 217.9±72.2 counts per minute) than controls (P<0.001).
Conclusions: Stroke survivors accrued a lower volume of PA, higher volume of sedentary time, and exhibited accrual patterns of more prolonged sedentary bouts and shorter, lower intensity activity breaks compared with persons without stroke.

Division of Orthopaedic Trauma and Adult Reconstruction, Department of Orthopaedic Surgery, Cooperman Barnabas Medical Center/Jersey City Medical Center - RWJBarnabas Health, 377 Jersey Ave, Suite 550, Jersey City, NJ 07302 USA.
Background: Acute extra-articular distal humerus fractures (DHFs) continue to pose a treatment challenge for many orthopedic surgeons. The aim of this study was to provide a comprehensive review of treatment principles, while reporting union rates, time to union, complication rates, and outcome measures following operative and non-operative management.
Methods: A systematic review was conducted utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines.
Comparative Analysis of Traumatic Brain Injury Severity in Motorcycle and Car Accident Victims Treated at Korle-Bu Teaching Hospital.
J West Afr Coll Surg
August 2024
Neurosurgery Unit, Department of Surgery, Korle-Bu Teaching Hospital, Accra, Ghana.
Background: Traumatic brain injury (TBI) is one of the common causes of long-term disabilities, with about 10 million deaths annually.
Objectives: Our aim is to compare the severity and outcomes of TBI between motorcycle and car accident victims.
Materials And Methods: A prospective cohort study focusing on TBI patients.
Restoring leg length during total hip arthroplasty (THA) for femoral neck fracture is challenging due to the lack of an intact femoral neck on the fractured side. Thus, templating methods typically use size of the intact contralateral hip to estimate length. Common reference points include the distance from the lesser trochanter to the center of the femoral head (LTC) and femoral head diameter (FHD).

Background: Acute kidney injury (AKI) occurs in up to 50% of cardiac surgical patients and is often hemodynamically mediated. Point-of-care ultrasound is a non-invasive tool that has the potential to characterize intrarenal hemodynamics and predict the risk of AKI.
Objectives: We aimed to determine the predictive characteristics of intrarenal arterial and venous Doppler markers for postoperative AKI in cardiac surgical patients.
Incidence, Prediction, and Prevention of Fractures After Kidney Transplantation: A Systematic Review Protocol.
Can J Kidney Health Dis

Department of Medicine, Western University, London, ON, Canada.
Background: Kidney transplant recipients are uniquely exposed to the disordered bone metabolism associated with chronic kidney disease beginning before transplantation followed by chronic corticosteroid use after transplantation. Previous efforts to synthesize the rapidly accruing evidence regarding estimation and management of fracture risk in kidney transplant recipients are outdated and incomplete.
Objective: To synthesize the evidence informing the overall incidence, patient-specific risk prediction, and methods of prevention of fractures in patient living with a kidney transplant.
