Background: Streptococcus pneumoniae is considered the leading bacterial cause of pneumonia in adults. Yet, it was not commonly detected by traditional culture-based and conventional urinary testing in a recent multicenter etiology study of adults hospitalized with community-acquired pneumonia (CAP). We used novel serotype-specific urinary antigen detection (SSUAD) assays to determine whether pneumococcal cases were missed by traditional testing. Methods: We studied adult patients hospitalized with CAP at 5 hospitals in Chicago and Nashville (2010-2012) and enrolled in the Etiology of Pneumonia in the Community (EPIC) study...

C-Mannosylation, a protein-modification found in various eukaryotes, involves the attachment of a single mannose molecule to selected tryptophan residues of proteins. Since C-mannosyl tryptophan (CMW) was detected in human urine, it is generally thought that CMW is not catabolized inside our body and instead is excreted via the urine. This paper reports enrichment of a bacterial consortium from soil that degrades CMW. The bacteria grew in minimal medium supplemented with CMW as the carbon source. Interestingly, even after successive clonal picks of individual colonies, several species were still present in each colony as revealed by 16S rRNA gene sequence analysis, indicating that a single species may not be responsible for this activity...

AIMS: We aimed to investigate the age-associated changes in movement coordination between the urinary bladder and the urethra in rats. METHODS: A total of 17 female Sprague-Dawley rats were used. The rats were divided into young (3 months old) and middle-aged (12-15 months old) groups. In both groups, isovolumetric cystometry and urethral perfusion pressure (UPP) measurements were performed under urethane anesthesia. After the rhythmic bladder contractions stabilized, L-arginine, a nitric oxide (NO) substrate (100 mg/kg), was administered intravenously in both groups...

BACKGROUND: Urinary bladder dysfunction in the form of acontractile/hypocontractile bladder is very common after spinal cord injury and it may lead to recurrent urinary tract infection (UTI), stones formation, and deteriorating renal function. Conventionally, these patients evacuate their bladders by life-long clean intermittent catheterization (CIC) or an indwelling catheter (IC). For these patients, another option is to use innervated skeletal muscle wrap around the bladder to augment detrusor function and voluntary evacuation of bladder...

BACKGROUND: Postoperative urinary retention (POUR) appears to be a common complication in lower limb joint arthroplasty; however, reports on its incidence vary. There is no general consensus on its definition and there is no scientific evidence on treatment principles. We performed a prospective observational study to establish the incidence of POUR and its risk factors, including the preoperative postvoid residual urine volume and the perioperative fluid balance, in fast-track total joint arthroplasty (TJA)...

INTRODUCTION: Very early withdrawal from treatment in patients undergoing peritoneal dialysis (PD) is an increasingly important, but poorly understood, issue. Here, we identified the reasons and risk factors for very early withdrawal from PD. METHODS: Incident PD patients from The First Affiliated Hospital of Sun Yat-sen University above 18 years who started treatment between January 1 2006 and December 31 2011 were included. Cessation of PD therapy within the first 90 days after beginning dialysis was classified as very early withdrawal...

Underactive bladder (UAB) or detrusor underactivity (DU) is a common yet still poorly understood urological problem. In addition to true detrusor failure and neuropathy, the inhibitory effects of detrusor contraction by the striated urethral sphincter and the bladder neck through alpha-adrenergic activity may also play a role in the development of UAB or DU. Treatment of UAB or DU aims to reduce the postvoid residual (PVR) urine volume and increase voiding efficiency, either by spontaneous voiding or abdominal straining...

Thyreostatic compounds, such as thiouracil (TU) are orally active drugs that can be used to increase the weight of cattle before slaughter. Due to potentially teratogenic and carcinogenic effects of their residues on public health, the use of thyreostats in animal production has been banned in the European Union since 1981. Systematic detection of low concentrations of thiouracil in the urine of livestock in many countries is believed to be of endogenous origin due to the use of Brassicaceae plants in the animal diet...

The ureters are retroperitoneal structures controlling urine transport from the kidneys to the bladder. Because of the relative scarcity of data on the biomechanical properties of human ureter and the established importance of knowing these properties for understanding its physiology, we initiated biomechanical studies in cadaveric tissue. Herein, we report definite zero-stress/no-load geometrical characterization at 15 regions along the ureter of human cadavers aged 23-82 years, estimating the opening angle, circumferential residual strains, axial curvature, and dimensional parameters...

PURPOSE: To analyze the 12-month outcomes of low-powered holmium laser enucleation of the prostate (LP-HoLEP) for patients with symptomatic benign prostatic obstruction (BPO). METHODS: A total of 54 patients with symptomatic BPO were treated with LP-HoLEP. All patients were treated by two experienced LP-HoLEP surgeons. A 50-W Ho:YAG laser was used at 39.6-W (2.2 J, 18 Hz). All patients were assessed preoperatively by International Prostate Symptom Score (IPSS), quality of life (QoL), maximum flow rate (Qmax), post-void residual urine (PVR), PSA, and whole prostate volume measurement by transrectal ultrasound...

Glycosaminoglycan (GAG) catabolism involves endo-hydrolysis of polysaccharides followed by the sequential removal of the non-reducing end residue from the resulting oligosaccharides by exo-enzymes. In the inherited metabolic disorder, mucopolysaccharidosis type I (MPS I), a deficiency in the exo-enzyme, α-l-iduronidase, prevents removal of α-l-iduronic acid residues from the non-reducing end of the GAGs, heparan sulphate (HS) and dermatan sulphate (DS). The excretion of partially degraded HS and DS in urine of MPS I patients has long been recognized, but the question of whether they do indeed reflect GAG load in a particular tissue has not been addressed - an important issue in the context of biomarkers for assessment of disease burden in MPS I...

Inguinal herniation of urinary bladder is uncommon and usually an incidental finding in asymptomatic patients. In some of these patients, residual urine volume and consequently, urinary tracer activity can be higher in the herniated bladder than the native bladder, in which case interpretation can be challenging on conventional planar imaging. We describe an interesting case of physiological activity in a herniated bladder simulating a "tear-drop". This case serves an important reminder that whilst F-18 NaF PET-CT has a similar spectrum of urinary activity to conventional bone scintigraphy; morphological correlation on hybrid imaging is invaluable in ensuring the physiological nature of uptake...

AIM: Albumin can be covalently modified at surface lysine residues and thus the circulation contains a mixture of native albumin (i.e. not modified) and albumin with varying degrees of modification. Uptake and lysosomal degradation of glomerular filtered albumin by proximal tubular cells via the megalin scavenger receptor is considered an important mechanism to limit albumin loss in the urine. However, whether this is a general mechanism of tubular uptake of albumin or if this is restricted to modified albumin is unknown...
