I-Jen Wang, Wilfried J J Karmaus
Background: Phthalate exposure may increase the risk of asthma. Little is known about whether oxidative-stress related genes may alter this association. First, this motivated us to investigate whether genetic polymorphisms of the oxidative-stress related genes glutathione S-transferase Mu 1 (GSTM1), glutathione S-transferase pi 1 (GSTP1), superoxide dismutase 2 (SOD2), catalase (CAT), myeloperoxidase (MPO), and EPHX1 in children are associated with phthalate urine concentrations. Second, we addressed the question whether these genes may affect the influence of phthalates on asthma...

Sows (n = 126) were administered penicillin G; urine, collected at slaughter, was screened by kidney inhibition swab (KIS; 4 h testing time) and then stored at -80 °C (∼1200 days) until analysis by lateral flow assay (LF, ∼5 min testing time) and tandem quadrupole LC-MS/MS (TQ) analysis. The stability of penicillin in urine during storage was verified using TQ analyses. Quantitative results were well-correlated (R(2) = 0.98) with only a ∼10% decrease in penicillin concentration during the 3-year storage period...

In BRCA1/2 families, early-onset breast cancer (BrCa) cases may be also observed among non-carrier relatives. These women are considered phenocopies and raise difficult counselling issues concerning the selection of the index case and the residual risks estimate in negative family members. Few studies investigated the presence of potential genetic susceptibility factors in phenocopies, mainly focussing on BrCa-associated single-nucleotide polymorphisms. We hypothesized that, as for other Mendelian diseases, a revertant somatic mosaicism, resulting from spontaneous correction of a pathogenic mutation, might occur also in BRCA pedigrees...

Most patients initiating hemodialysis have residual renal function (RRF). Whereas RRF is monitored prior to commencing hemodialysis, once dialysis is started most centres simply rely on dialyzer urea clearance to determine adequate uremic toxin clearance and disregard the effect of RRF. However sustaining RRF is important for the dialysis patient, as RRF reduces inter-dialytic weight gains, increases middle molecule and protein bound toxin clearances and is associated with better quality of life assessments...

We investigated urine nerve growth factor (NGF) levels and erectile dysfunction in diabetic men <45 years of age. Urinary NGF levels were measured in 72 diabetic men and 20 control subjects without lower urinary tract symptoms or erectile dysfunction. Participants were evaluated using the International Prostate Symptom Score, quality of life index, Overactive Bladder Symptom Score (OABSS), the five-item version of the International Index of Erectile Function questionnaire (IIEF-5), the patient perception of bladder condition questionnaire, measurement of flow rate and post-void residual urine volume...

INTRODUCTION: Residual renal function (RRF) and phosphaturia had not stimulated particular interest in studies regarding patients on hemodialysis. In the current year the Authors have selected a series of patients with RRF undergoing infrequent hemodialysis treatments. PURPOSE: The Authors have carried out a study of the phosphate balance in patients on infrequent hemodialysis with the hypothesis that the phosphaturia was always neglected in hemodialysis patients, but it could represent a positive impact element on the cardiovascular events and mortality in hemodialysis...

BACKGROUND: Few studies have evaluated the prognostic value of dialysis dose in twice-weekly hemodialysis (HD). A single-pool Kt/V (spKt/V) over 1.70 may benefit patients receiving twice-weekly maintenance HD. METHODS: This is a multicenter randomized controlled trial performed on 163 patients from 17 dialysis centers in Shanghai who were allocated to high- (n = 98) and standard-dose groups (n = 65) and followed through 96 weeks of study period. Therapeutic approaches were given to increase spKt/V to over 1...

REVIEW
Cheuk Chun Szeto, David W Johnson
Long-term exposure to a high glucose concentration in conventional peritoneal dialysis (PD) solution has a number of direct and indirect (via glucose degradation products [GDP]) detrimental effects on the peritoneal membrane, as well as systemic metabolism. Glucose- or GDP-sparing strategies often are hypothesized to confer clinical benefits to PD patients. Icodextrin (glucose polymer) solution improves peritoneal ultrafiltration and reduces the risk of fluid overload, but these beneficial effects are probably the result of better fluid removal rather than being glucose sparing...

We report a case of borderline resectable(BR)pancreatic cancer, which was eligible for R0 resection following preoperative chemotherapy with GEM plus nab-PTX. A 77-year-old woman presented with brown urine and clay-colored stool. After further examination, she was diagnosed with obstructive jaundice due to pancreatic head cancer. Because the tumor was in contact with the region attached to the SMA nerve plexus, she was also diagnosed with BR-A pancreatic cancer. After 6 courses of preoperative GEM plus nab-PTX combination chemotherapy, she underwent subtotal stomach-preservingpancreaticoduodenectomy with SMV resection and right semicircular SMA nerve plexus dissection...
