Objective: This field study was designed to compare the level of styrene absorbed percutaneously with that absorbed by inhalation in a real situation in the fiberglass-reinforced polyester industry.
Methods: The study protocol consisted of comparisons of the patterns of urinary excretion of styrene metabolites by four groups of workers, all of whom performed the same task at the same time in the same workshop but wore the following different protective equipment: total protection with an insulating suit and mask, respiratory equipment only, percutaneous protection only, and no protection.
Results: The urinary excretion level of the group with total protection did not significantly differ from that of the group with respiratory protection only.
Conclusions: Precutaneous absorption is not a particularly important pathway for styrene absorption during stratification work in the polyester industry. Completely insulating personal protective equipment provides no greater level of protection than does a respirator at positive pressure alone.

Introduction: A strong and well-known association exists between salt consumption, potassium intake, and cardiovascular diseases. MINISAL-SIIA results showed high salt and low potassium consumption in Italian hypertensive patients. In addition, a recent Italian survey showed that the degree of knowledge and behaviour about salt was directly interrelated, suggesting a key role of the educational approach.

Purpose Of Review: This review highlights the latest findings regarding hypocitraturia in autosomal dominant polycystic kidney disease (ADPKD), from both experimental and clinical studies, exploring the underlying pathophysiology and potential therapeutic approach.
Recent Findings: Experimental studies have shown that the lodging of microcrystals in the tubules can trigger cyst formation and growth in polycystic kidney disease (PKD). ADPKD patients are prone to developing hypocitraturia in early stages, which could predispose to calcium microcrystal formation.
Urinary Endotrophin and Long-term Outcomes in Kidney Transplant Recipients.
Transplant Direct

Department of Nephrology, Odense University Hospital, Odense, Denmark.
Background: Kidney fibrosis is a suggested cause of kidney failure and premature mortality. Because collagen type VI is closely linked to kidney fibrosis, we aimed to evaluate whether urinary endotrophin, a collagen type VI fragment, is associated with graft failure and mortality among kidney transplant recipients (KTR).
Methods: In this prospective cohort study, KTR with a functioning graft ≥1-y posttransplantation were recruited; 24-h urinary endotrophin excretion was measured using an ELISA method.
Calcium to magnesium ratio as a superior biomarker for nephrolithiasis detection in primary hyperparathyroidism.

Primary hyperparathyroidism (pHPT) is marked by mineral imbalances, often leading to nephrolithiasis and osteoporosis. While imaging remains the cornerstone for stone detection, there is growing interest in biochemical markers that could enhance diagnostic accuracy. This study investigates the calcium-to-magnesium (Ca/Mg) ratio as a novel biomarker for nephrolithiasis, comparing its utility to traditional 24-h urinary calcium excretion and exploring its broader clinical implications.

Background: Advanced glycation end-products (AGEs) can enter patients' circulation through exogenous sources, such as enteral nutrition formulae. Circulating AGEs, specifically carboxymethyllysine, can promote insulin resistance and activation of pro-inflammatory pathways leading to oxidative stress, cell death, and organ failure. Suboptimal kidney function increases the risk of elevated circulating AGEs because levels are controlled through urinary excretion.
