The prevalence of idiopathic nephrolithiasis is increasing in rich countries. Dietary manipulation could contribute to the prevention of both its first appearance and the recurrence of the disease. The target of dietary treatment is to decrease the "urinary lithogenic risk factors" such as low urine volume, hypercalciuria, hyperoxaluria, hyperuricosuria,(More)
BACKGROUND A direct relation exists between sodium and calcium excretion, but randomized studies evaluating the sustained effect of a low-salt diet on idiopathic hypercalciuria, one of the main risk factors for calcium-oxalate stone formation, are still lacking. OBJECTIVE Our goal was to evaluate the effect of a low-salt diet on urinary calcium excretion(More)
Increasing urinary volume is an important tool in the prevention of calcium renal stones. However, the mechanism of how it actually works is only partially understood. This study aimed at assessing how urine dilution affects urinary calcium oxalate crystallization. A total of 16 male idiopathic calcium oxalate (CaOx) stone-formers and 12 normal male(More)
AIM To evaluate the contribution of family history of stones (FHS), up to second-degree relatives, on clinical course (age of first renal colic, bilateral disease, retained calculi, recurrences, urological procedures) of idiopathic calcium nephrolithiasis (ICN) and urinary parameters of lithogenic risk, a case-control study was carried out. METHOD(More)
Like other diseases striking predominantly the affluent societies, idiopathic nephrolithiasis is increasing in rich countries and appears to be closely related to dietary habits. In this review we summarize the latest evidence about the efficacy of dietary treatment for idiopathic calcium and uric acid stones, dealing especially with its effect on the(More)
OBJECTIVES To assess whether a normal-calcium, low-animal protein, low-salt diet is effective in reducing hyperoxaluria in idiopathic calcium oxalate nephrolithiasis compared with a traditional low-oxalate diet, routinely recommended by clinicians METHODS We treated 56 patients with idiopathic calcium oxalate stone formation who presented with mild(More)
Nutrition has been widely recognized to influence the risk of kidney stone formation. Therefore the aim of our study was to assess: a) whether usual diet of women with idiopathic calcium nephrolithiasis (ICN) living in Parma (Northern-Italy) is different compared to healthy controls, b) how their diet differs from Italian National guidelines and c) whether(More)
OBJECTIVES To establish the predictive value on mortality after 2 months from hospital admission of two laboratory markers of nutritional and inflammatory status, high-sensitivity C-reactive protein (hs-CRP) and prealbumin, in a cohort of frail multimorbid elderly without terminal illness. DESIGN Prospective cohort study. SETTING Internal medicine ward(More)
BACKGROUND Over 20% of hospital bed use is inappropriate, implying a waste of resources and the increase of patient iatrogenic risk. METHODS This is a cluster, pragmatic, randomised controlled trial, carried out in a large University Hospital of Northern Italy, aiming to evaluate the effect of a strategy to reduce unnecessary hospital days. The primary(More)
OBJECTIVES To identify the role of chronic comorbidities, considered together in a literature-validated index (Cumulative Illness Rating Scale, CIRS), and antibiotic or proton-pump inhibitor (PPI) treatments as risk factors for hospital-acquired Clostridium difficile infection (CDI) in elderly multimorbid hospitalised patients.
