BACKGROUND: Decreased residual urine volume (RUV) is associated with higher mortality in hemodialysis (HD). However, few studies have examined RUV in patients on HD in Sub-Saharan Africa. The aim of this study was to identify predictors of RUV among incident hemodialysis patients in Kinshasa. METHODS: This historical cohort study enrolled 250 patients with ESRD undergoing hemodialysis between January 2007 and July 2013 in two hemodialysis centers in Kinshasa. RUV were collected over 24 h at the initiation of HD and 6 and 12 months later during the interdialytic period...

BACKGROUND: Incremental hemodialysis (HD) regimen has recently gained attention. However, its efficacy and safety, compared with conventional thrice-weekly HD, are controversial and previous research results are not convincing. We sought to conduct a meta-analysis to evaluate the benefits and limitations of incremental HD regimen in patients with end-stage renal disease. METHODS: We searched PubMed, Embase, and the Cochrane Central Register databases for controlled trials published until January 2017...

The use of frequent hemodialysis (HD) is growing, with the hope of improving outcomes in end-stage renal disease. We narratively review the three randomized trials, 15 comparative cohort studies, and several case series of frequent HD that empirically demonstrate the potential efficacy and adverse effects of these regimens. Taken together, the randomized studies suggest frequent HD may result in left ventricular mass regression. This effect is most pronounced when left ventricular mass is abnormal, but attenuated by significant residual urine output...

Lower urinary tract abnormalities are difficult to resolve in pediatric kidney transplant patients. Measure of residual urine, voiding cystourethrography, retrograde urethrography, cystometry, electromyography of urethral external sphincter muscle, urethrometry, and uroflowmetry are the primary methods for evaluation of lower urinary tract abnormalities. Endoscopic resection or ablation of urethral valves is required in children with posterior urethral valve to treat obstruction, but bladder function does not always recover and may deteriorate to end-stage renal failure even after the obstruction is released...

BACKGROUND: Congenital adrenal hyperplasia (CAH) is an autosomal recessive condition resulting in excess androgen production. Females are typically born with ambiguous genitalia and often undergo feminising genitoplasty in infancy or childhood. Recently, there has been considerable international debate as to whether distressing urinary symptoms in CAH patients are truly present and, if so, whether these urinary problems are a consequence of the feminising genitoplasty. OBJECTIVE: To identify and assess any urinary symptoms in an Australian cohort of adolescent and adult women with CAH who have undergone feminising genitoplasty in infancy, childhood or adolescence as a part of their management...

BACKGROUND The purpose of the present study was to assess the effect of luteolin and solifenacin on diabetic cystopathy (DCP) and to investigate the mechanism of action. A novel link between the overexpression of c-Kit in the bladder and voiding dysfunction was identified in rats with DCP. MATERIAL AND METHODS A rat model of DCP was successfully established by intraperitoneal injection of streptozotocin and a diet high in glucose and lipids, and animals were treated with luteolin and solifenacin. The effect of luteolin and solifenacin on urinary dysfunction in DCP rats was investigated by assessing bladder pressure and performing a volume test...

BACKGROUND: Glyphosate (GLY) is the most heavily used herbicide worldwide but the extent of exposure in human pregnancy remains unknown. Its residues are found in the environment, major crops, and food items that humans, including pregnant women, consume daily. Since GLY exposure in pregnancy may also increase fetal exposure risk, we designed a birth-cohort study to determine exposure frequency, potential exposure pathways, and associations with fetal growth indicators and pregnancy length...

Background: No study has assessed whether the prognosis of coexisting diabetes mellitus and chronic kidney disease (DM-CKD) is dictated by DM per se or by the extent of proteinuria. Methods: In this pooled analysis of four prospective studies in CKD patients treated with drugs inhibiting the renin-angiotensin system, we compared the risk of all-cause mortality, fatal and non-fatal cardiovascular (CV) events and end-stage renal disease (ESRD) between patients with (n = 693) and without diabetes (n = 1481) stratified by proteinuria level (<0...

In this study we describe an approach to enhance the sensitivity of an online comprehensive two-dimensional liquid chromatography (LC × LC) high-resolution mass spectrometry method for the separation and detection of trace levels of anabolic-steroid residues in complex urine matrices. Compared to one-dimensional liquid chromatography (1D-LC), LC × LC methods offer higher separation power, thanks to the combined effect of two different selectivities and a higher peak capacity. However, when using state-of-the-art LC × LC instrumentation, the price paid for the increase in separation power is a decrease in sensitivity and detectability of trace-level analytes...

The secretion of small molecules by the proximal tubules of the kidneys represents a vital homeostatic function for rapidly clearing endogenous solutes and medications from the circulation. After filtration at the glomerulus, renal blood flow is directed through a network of peritubular capillaries, where transporters of the proximal tubules actively secrete putative uremic toxins and hundreds of commonly prescribed drugs into the urine, including protein-bound substances that cannot readily cross the glomerular basement membrane...

The removal of the widely used antibiotic norfloxacin (NOR), the presence of which has been reported in natural water, was evaluated using rice (RH) and coffee (CH) husk wastes as adsorbents. Low particle sizes and natural pH in distilled water favored NOR elimination in both materials. In order to investigate the type of adsorption, the data was adjusted to the Langmuir, Freundlich and Redlich-Peterson isotherms. The best fit for the Langmuir and Redlich-Peterson isotherms suggested a monolayer-type adsorption model...

OBJECTIVE: Mirabegron is widely considered as an effective and safe drug for patients with overactive bladder (OAB). However, there is no evidence regarding the efficacy of mirabegron in human T cell lymphotropic virus-1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) patients with OAB symptoms. The aim of the present study was to clarify the efficacy of mirabegron in HAM/TSP patients with OAB symptoms. METHODS: The present study evaluated the efficacy of mirabegron treatment (50 mg, once daily) in nineteen HAM/TSP patients with OAB symptoms by assessing subjective symptoms using the overactive bladder symptom score (OABSS) and International Prostate Symptom Score (IPSS) before and 12 weeks after administration...

An 11-year-old boy was referred to our department with the chief complaint of acute urinary retention. He had had a history of viral enteritis a few days before the onset of dysuria. He presented with a slight fever, mild headache and weakness of the extremities. A cerebrospinal fluid examination showed the elevation of cell number (cell number : 158/3, polynuclear cells : 29/3, and mononuclear cells : 129/3). Although spinal magnetic resonance imaging (MRI) did not show abnormal findings, fluid attenuated inversion recovery (FLAIR) image of the brain MRI showed a high signal area on the cerebral cortex...

Storage of drug-based evidence inside sealed safes may allow chemical vapors to accumulate, creating concerns of drug exposure by inhalation, or the possibility of cross-contamination of drug evidence. Air samples were taken from inside eight drug safes and one small storage room at nine city and country police stations, as well as a large centralized drug evidence storage vault, in New South Wales (NSW), Australia. Sorbent tubes containing charcoal were used to determine whether any drug residues could be detected in the air, and to identify the types of chemicals present...

A 51-year-old male presented 25 years ago with excessive sweating and haematuria. Blood pressure was labile. CT abdomen showed a large right-sided adrenal mass. Two 24-h urine collections showed elevated urinary catecholamines. Right adrenal resection was performed; a phaeochromocytoma (PC) was confirmed histologically. Two decades later, the patient represented with excessive sweating and measured variable blood pressure readings. Measurement of plasma metanephrines (PMets) showed elevated normetanephrine (NMN) [50,250 (R...
