Hereditary (familial) amyloid polyneuropathy (FAP) is a systemic disease that includes a sensorimotor polyneuropathy related to transthyretin (TTR) mutations. So far, a scale designed to classify the severity of this disease has not yet been validated. This work proposes the implementation of an artificial neural network (ANN) in order to develop a severity scale for monitoring the disease progression in FAP patients. In order to achieve this goal, relevant symptoms and laboratory findings were collected from 98 Brazilian patients included in THAOS - the Transthyretin Amyloidosis Outcomes Survey...

In up to 10% of patients who experience abdominal trauma, renal and urogenital systems will be involved. In polytrauma patients with other potentially life-threatening injuries, renal and genitourinary trauma may be overlooked initially, but a delayed or missed diagnosis of these injuries may result in preventable complications. This review provides a best-practice approach to the diagnosis and management of renal and genitourinary injuries, with an emphasis on the systematic approach needed to identify subtle injuries and avoid long-term urinary sequelae such as hypertension, incontinence, erectile dysfunction, chronic kidney disease, and nephrectomy...

Primary hyperoxaluria (PH) patients overproduce oxalate because of rare genetic errors in glyoxylate metabolism. Recurrent urolithiasis and/or progressive nephrocalcinosis are PH hallmarks and can lead to kidney damage, systemic oxalosis and death. Based on previous studies, we hypothesised that treatment with the oxalate-metabolizing bacterium Oxalobacter formigenes would mediate active elimination of oxalate from the plasma to the intestine of PH patients, thereby reducing urinary oxalate excretion (Uox)...

The main aim in the treatment of renal stones is to clearance of the stones completely with the least morbidity. Parallel to the improvements in technology during recent years, new flexible ureterorenoscopes and effective lithotripters such as holmium laser have been developed, thus retrograde intrarenal surgery (RIRS) has become an efficient and safe option in the management of urinary system stone disease with a gradually increasing popularity. Therewithal, innovations in auxiliary equipment such as guide-wires, ureteral access sheath and stone baskets have made this procedure more effective...

REVIEW
John T Stoffel
Many multiple sclerosis (MS) patients are affected by urinary retention. Common causes include neurogenic underactive bladder and/or bladder outlet obstruction from detrusor sphincter dyssynergia. Systemic review of contemporary MS urodynamic studies demonstrates that 53% of MS patients have detrusor overactivity, 43% have detrusor sphincter dyssynergia, and 12% have atonic bladder (12 studies, 1524 patients). There is no standard definition of MS-related urinary retention, but greater than 300 mL is a proposed threshold value for the condition based on literature review...

AIMS: Urodynamics (UDS) is widely used for the diagnosis of lower urinary tract dysfunction. Air-Charged catheters (ACC), one of the newer technologies for UDS pressure recording, has been adopted in growing numbers around the world for the past 15 years. Currently, there is a lack of published studies characterizing specific performance of the ACC. Since linearity, hysteresis, pressure drift, and frequency response are important components in characterizing accuracy for catheter-manometer systems; this study aimed to assess these four aspects in ACC...

INTRODUCTION: Growing resistance of pathogens to antibiotics, including cross-resistance to other antimicrobial classes that are used in the treatment of recurrent infections of the lower urinary system in children demands constant control of issues of regional antibiotic resistance. In the present days, in the empirical treatment of such patients physicians still choose medications with preserved activity in relation to E. coli. The aim of our study was to investigate the regional features of microbial landscape of urine in children with cystitis and study the efficacy of 7-day administration of Furamag medicinal drug for the treatment of recurrent episodes of this disease in children...

OBJECTIVE: Leukocyte telomere length (LTL) is a biomarker of cellular aging affected by chronic stress. The relationship of LTL to the stress hormones, cortisol and catecholamines, is unclear, as are possible differences between healthy controls (HC) and individuals with Major Depressive Disorder (MDD). This small pilot study is the first to examine the relationship between cortisol, catecholamines and LTL specifically in un-medicated MDD in comparison with HC. METHODS: Participants included 16 un-medicated MDD subjects and 15 HC for assay of LTL, 12-hour overnight urinary free cortisol and catecholamine levels...

Ethyl glucuronide (EtG) is a direct alcohol marker, which is widely used for clinical and forensic applications, mainly for abstinence control. However, the instability of EtG in urine against bacterial degradation or the post-collectional synthesis of EtG in contaminated samples may cause false interpretation of EtG results in urine samples. This study evaluates the potential of sodium azide in tubes used for urine collection to hinder degradation of ethyl glucuronide by bacterial metabolism taking place during growth of bacterial colonies...

The metabolism of flavonoids derived from orange juice in Chinese volunteers has not been well investigated. With the ultra-fast liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry (UFLC-Q-TOF-MS/MS) system, orange juice-derived flavonoids, as well as metabolites contained in urine collected from healthy Chinese volunteers after consumption of 250mL orange juice, were systematically identified and quantified. Finally, a total of 9 flavonoids and 30 metabolites were detected. Obtained results revealed that flavonoids derived from orange juice underwent extensive phase II metabolism in human, mainly comprising glucuronidation and sulfation...

L-Homoarginine (hArg) and guanidinoacetate (GAA) are produced from L-arginine (Arg) by the catalytic action of arginine:glycine amidinotransferase. Guanidinoacetate methyltransferase methylates GAA on its non-guanidine N atom to produce creatine. Arg and hArg are converted by nitric oxide synthase (NOS) to nitric oxide (NO). NO is oxidized to nitrite and nitrate which circulate in the blood and are excreted in the urine. Asymmetric dimethylarginine (ADMA), an NOS inhibitor, is widely accepted to be exclusively produced after asymmetric N (G)-methylation of Arg residues in proteins and their regular proteolysis...

Laparoscopic TAPP inguinal hernia repair is an established alternative to open hernia repair, which offers equivalent outcomes with less postoperative pain and faster recovery. Unfortunately, it remains technically challenging, requiring advanced laparoscopic skills which have limited its popularity among surgeons. The robotic platform has the potential to overcome these challenges. The objective of this study was to examine the long-term quality of life and outcomes following robotic assisted TAPP inguinal hernia repair, since these data have not been reported up to now...

Inflammatory and metabolic diseases can originate during early-life and have been correlated with shifts in intestinal microbial ecology. Here we demonstrate that minor environmental fluctuations during the early neonatal period had sustained effects on the developing porcine microbiota and host-microbe interface. These inter-replicate effects appear to originate during the first day of life, and are likely to reflect very early microbiota acquisition from the environment. We statistically link early systemic inflammation with later local increases in inflammatory cytokine (IL-17) production, which could have important enteric health implications...
