BACKGROUND: A decrease in absolute numbers (abs.) of circulating dendritic cells (DCs) and recruitment into target organs has been reported, but whether the level of proteinuria associates with circulating DC abs. has not been clarified. METHODS: We conducted a cross-sectional study of 210 patients with kidney disease aged 21-96 years who were admitted to our hospital for kidney biopsy in 2007-2010. For accuracy, the level of proteinuria was thoroughly measured by 24-h urine collection from patients in their admitted condition...

INTRODUCTION AND HYPOTHESIS: Urethral diverticulum in pregnancy is a rare finding and difficult to diagnose. The classical triad of dysuria, dyspareunia and dribbling of urine is found in a minority of women. METHODS: A young woman presented during the first trimester of pregnancy with vaginal and suprapubic pain as well as voiding difficulty. Ultrasound demonstrated a 2-cm hypoechoic lesion to the left of the urethra. She went on to have a cystoscopy that demonstrated a diverticulum...

BACKGROUND: Vitamin D repletion is recommended for secondary hyperparathyroidism (SHPT) and associated vitamin D insufficiency (VDI) in chronic kidney disease (CKD), but optimal levels of serum total 25-hydroxyvitamin D remain undefined. Clinical practice guidelines target sufficiency, whereas recent data indicate that higher levels are required to control the elevation of intact parathyroid hormone (iPTH) as CKD advances. This secondary analysis of 2 randomized controlled trials seeks to identify the minimum level of mean serum 25-hydroxyvitamin D required to control SHPT arising from VDI in stage 3 or 4 CKD...

Blood trihalomethanes (THMs) and urinary haloacetic acids (HAAs) are the leading candidate biomarkers for disinfection byproduct (DBP) exposure. However, no studies have assessed the exposure profiles, temporal variability, and potential predictors of these biomarkers during pregnancy. Here we collected blood (n = 4304) and urine samples (n = 4165) from 1760 Chinese pregnant women during early, mid-, and late pregnancy, which were separately analyzed for 4 THMs and 2 HAAs. We calculated the intraclass correlation coefficients (ICCs) to assess the variability of these biomarkers and estimated their correlations with sociodemographic, water-use behavioral, dietary and sample collection factors using mixed models...

Chronic exposure to inorganic arsenic (As) is associated with numerous adverse effects. Argentina is one of the countries affected by arsenicism; however, there are few studies that evaluate inorganic As exposure and its effects on child population. The aim of this study is to evaluate exposure to As through water and food in child populations living in the provinces of Santiago del Estero and Chaco (n = 101), and to determine the impact of this exposure analysing biomarkers of exposure (urine and hair As contents) and effect [8-oxo-7,8-dihydro-2'-deoxyguanosine (8-OHdG)]...

2,2',4,4'-Tetrabromodiphenyl ether (BDE-47) is a predominant polybromodiphenyl ether congener in the environment. Its absorption, excretion, and metabolism in animals have been investigated; however, the distribution of BDE-47 and its metabolites in excreta and blood at steady-state conditions has been unclear. In the present study, we addressed the issue by determining the amounts of BDE-47, eight monohydroxylated metabolites (OH-BDEs), and 2,4-dibromophenol (2,4-DBP) in serum, urine, and feces of gpt delta transgenic mice orally administered BDE-47 at 1...

The authors aim to report a case of surreptitious administration of a synthetic cannabinoid (SC) and the subsequent toxicological investigations to be able to document accurately the case for submission at a hearing. A dealer gave surreptitiously a substance to two juvenile migrants who experienced shakings and faintness. The laboratory received a blood sample from each of the two victims, who, according to the investigators, were probably exposed to SGT-151, a SC, also known as CUMYL-PEGACLONE. Blood and urine specimens from the dealer, who claimed being a user of SGT-151 were received at the same time...

To simplify the pretreatment process of complex samples is a key step for rapid detection. Herein, we report a single-step method to rapidly extract analytes with liquid-phase microextraction (LPME) from complex samples on a superwetting porous silicon (PSi) for onsite detection with surface-assisted laser desorption/ionization mass spectrometry (SALDI-MS). The operation time is less than 3 min with this simple method. The limit of detection (LOD) of malachite green in lake water is lowered to 10-13 M, that of verapamil and methadone in whole blood is down to 10-11 M and 10-13 M, in urine is 10-13 M and 10-14 M, respectively; and the ranges of quantification is up to 8 or 9 orders of magnitude with high precision (coefficients of determination (R2 ) > 0...
