Article Synopsis
  • A recent clinical trial found that a dietary supplement of essential amino acids (EAAs) is more effective than whey protein in improving physical function among older adults with low physical function.
  • The study identified 20 proteins that were differentially expressed between the EAA and whey groups, with five proteins in the EAA group showing significantly higher expression linked to increased energy for muscle and cardiac strength.
  • Overall, the research suggests that EAAs could enhance muscle strength and physical performance in older adults, highlighting their potential benefits over traditional whey protein.

Background: Delirium is a common medical condition that is highly prevalent in older adults who are at increased risk for its development with any illness, post-surgery or during hospitalization. The purpose of our study was to evaluate the health literacy of older adult patients and their caregivers about delirium, offer a brief educational intervention, and reevaluate their knowledge post intervention.

Materials And Methods: We conducted a quality improvement project, focused on delirium health literacy in older adult patients ≥60 years and their caregivers.

We have investigated the hypothesis that nutritional supplementation of the diet in low-physical-functioning older individuals with a specially formulated composition based on essential amino acids (EAAs) would improve physical function as compared to supplementation with the same amount of whey protein. A third group of comparable volunteers were given nutrition education but no supplementation of the diet. After 6 weeks of whey protein supplementation (n = 32), there was no effect on the distance walked in 6 minutes, but the distance walked improved significantly from the pre-value after 12 weeks of whey supplementation.

In this work, we use existing particulate matter (PM) data from Dakar, Senegal, satellite aerosol optical depth (AOD) and the Weather Research and Forecasting (WRF) model to evaluate the role of dust transport from the Sahara and PM concentrations and exposure into other administrative districts of Senegal during 2015 and 2016. We also use data from the Ministry of Health to examine spatial and temporal patterns of acute respiratory infections, asthma, bronchitis, and tuberculosis across Senegal with an emphasis on Northern Hemisphere winter December-February, when air quality is poor, and June-August when there is an improvement in air quality. Measurements in Dakar, Senegal, suggest hazardous PM concentrations associated with Saharan dust storms but lower PM concentrations during the summer.

OBJECTIVES The purpose of this study was three-fold: to identify which behavioural, communicative and personal presentation characteristics most closely represent patients' views of professionalism; to determine whether patients perceive resident doctors as displaying these characteristics, and to explore whether or not resident doctor professional behaviour creates an impression of clinical competence to the degree where patients perceive a decreased need for Attending Physician involvement. METHODS We carried out a descriptive, cross-sectional study at an academic centre. An anonymous, voluntary four-question survey with multiple items was administered to all adult patients or the parents of paediatric patients attending an ophthalmology clinic who were seen by a resident doctor followed by an Attending Physician.
