New evidence shows that older adults need more dietary protein than do younger adults to support good health, promote recovery from illness, and maintain functionality. Older people need to make up for age-related changes in protein metabolism, such as high splanchnic extraction and declining anabolic responses to ingested protein. They also need more(More)
The aging process is associated with gradual and progressive loss of muscle mass along with lowered strength and physical endurance. This condition, sarcopenia, has been widely observed with aging in sedentary adults. Regular aerobic and resistance exercise programs have been shown to counteract most aspects of sarcopenia. In addition, good nutrition,(More)
Protein energy wasting (PEW) is common in patients with chronic kidney disease (CKD) and is associated with adverse clinical outcomes, especially in individuals receiving maintenance dialysis therapy. A multitude of factors can affect the nutritional and metabolic status of CKD patients requiring a combination of therapeutic maneuvers to prevent or reverse(More)
Iodine and gadolinium-based contrast induced nephropathy is the third leading cause of hospital-acquired acute kidney injury. It is essentially observed in patients with defined risk factors and is associated with increased morbidity and mortality. The prevention of contrast induced nephropathy consists in volume expansion through intravenous sodium(More)
We report the case of a 35-year-old man with no cardiovascular morbidity, presenting with acute flank pain, microscopic haematuria and normal blood pressure. Initially diagnosed as a ureteral colic, the patient was recovered 6 weeks later with severe hypertensive crisis. Further investigations revealed a massive renal infarction secondary to medial(More)
Vitamin D is the main hormone of bone metabolism. However, the ubiquitary nature of vitamin D receptor (VDR) suggests potential for widespread effects, which has led to new research exploring the effects of vitamin D on a variety of tissues, especially in the skeletal muscle. In vitro studies have shown that the active form of vitamin D, calcitriol, acts in(More)
Leptin and adiponectin are adipokines with respective pro-atherogenic and anti-atherogenic properties, defining the plasma leptin/adiponectin ratio as a novel marker for atherosclerosis. In non-renal patients, both hyperleptinemia and hypoadiponectinemia are associated with cardiovascular complications. In peritoneal dialysis (PD) patients, the(More)

The adipose tissue has pleiotropic functions far beyond the mere storage of energy, and it secretes a number of hormones and cytokines, called adipokines, which have biological effects that impact heath and disease. Adipokines are markedly elevated in the plasma of uremic patients, mainly due to decreased renal excretion. They have pluripotent signaling(More)
BACKGROUND Falls have been insufficiently studied in patients on maintenance haemodialysis (MHD). This study assessed the incidence and complications of severe falls and the ability of risk factors, including the Performance-Oriented Mobility Assessment (POMA) test, to predict them in this population. METHODS All patients on MHD from our centre were asked(More)
Impaired glucose tolerance or diabetes mellitus are frequent complications after organ transplantation, and are usually attributed to glucocorticoid and immunosuppressive treatments. Liver transplantation results in total hepatic denervation which may also affect glucoregulation. We therefore evaluated postprandial glucose metabolism in a group of patients(More)
