Background: The use of body-warming systems is recommended by international anaesthesia societies for patients undergoing surgery. Limited research is however available on the influence of positioning of forced-air warming blankets for patients undergoing spinal surgery. This study aimed to investigate how patients' intra-operative body temperature was affected by the position of forced-air warming blankets while undergoing spinal surgery on a spinal table.

This scoping review aimed to provide an overview of all scientifically relevant information presented on the application of the FII in the prevention and management of insulin resistance and diabetes. The Arksey and O'Malley framework and the PRISMA Extension for Scoping Reviews 22-item checklist were used to ensure that all areas were covered in the scoping review.

Amidst low intakes of dairy and dairy-related nutrients in South Africa, and to increase public awareness thereof, we aimed to develop and evaluate the usability of an application (app) to screen for dairy intake in higher income South African adults. In a consultative process, a dairy intake screener ('Dairy Diary') was developed as an eight-item quantitative FFQ with four types of commonly consumed local dairy products: milk, maas (fermented milk), yoghurt, and cheese.

Remaining in the emergency department for >12 h increases health care costs, morbidity and mortality rates and leads to crowding and lower patient satisfaction.The aim of this research was to describe the areas of delay related to prolonged length of stay in the emergency department of an academic hospital.

The purpose of this study was to describe the factors that increase length of stay (LOS) among elderly patients who have had hip fracture surgery.
Methods: A retrospective review of patient records of elderly (>65 years) patients who had hip fracture surgery in a public hospital in South Africa.
Bioelectrical impedance analysis (BIA) is a practical alternative to dual-energy X-ray absorptiometry (DXA) for determining body composition in children. Currently, there are no population specific equations available for predicting fat-free mass (FFM) in South African populations. We determined agreement between fat-free mass measured by DXA (FFM) and FFM calculated from published multi-frequency bioelectrical impedance prediction equations (FFM); and developed a new equation for predicting FFM for preadolescent black South African children.

Both body composition and vitamin D play an important role in bone health. This study aimed to describe bone health, body composition, and vitamin D status, and the relationship between these among a group of conveniently sampled black preadolescent South African children ( = 84) using a cross-sectional study.

The current postgraduate research supervision culture and supervision practices should change. Moving towards person-centered research supervision practices may enhance the research environment, as healthful relationships between supervisors and postgraduate students may lead to increased postgraduate research outcomes.

In a randomized, parallel, controlled study design, sixty-four subjects having the metabolic syndrome (twenty-nine men, thirty-five women) with a mean age of 45 (sd 10) years and who met the selection criteria were all fed a 3-week run-in control diet. Hereafter, participants were grouped according to gender and age and then randomized into three groups receiving a controlled feeding diet including walnuts, or unsalted cashew nuts or no nuts for 8 weeks.
