The hemodialysis (HD) session per se is a catabolic event contributing to protein–energy wasting via several mechanisms including nutrient losses. Amino acids (AAs) losses in the dialysate are estimated from 6 to 10 g per treatment. The HD patient plasma AA concentration is usually lower than in normal subjects. This is even more marked in patients with long dialysis vintage or malnutrition.
The newly developed Low Physical Activity Questionnaire (LoPAQ) was designed to capture the low activity level among typically sedentary patients undergoing dialysis and correlated well with a physical activity questionnaire used in the general population. However, this instrument has not been validated against a more objective measure.
Although healthy dietary patterns are associated with decreased mortality in patients with chronic kidney disease (CKD), few patients receive dietitian counseling due to concerns such as dietitian availability, travel distance, and cost. Our objective was to determine the feasibility of dietary smartphone application–supported telecounseling to reduce sodium intake and improve dietary quality in patients with early CKD.
Testosterone deficiency is a common disorder among men treated with hemodialysis. The aim of our study was to evaluate the relationship between free testosterone levels and body composition, biochemical markers of nutritional status, and inflammation in men on hemodialysis.
