Serglycin is an intracellular proteoglycan with a unique ability to adopt highly divergent structures by glycosylation with variable types of glycosaminoglycans (GAGs) when expressed by different cell types. Serglycin is overexpressed in aggressive cancers suggesting its protumorigenic role. In this study, we explored the expression of serglycin in human glioma and its correlation with survival and immune cell infiltration. We demonstrate that serglycin is expressed in glioma and that increased expression predicts poor survival of patients...

BACKGROUND: Mortality in the immediate post-hemodialysis transition period is extremely high. Many end-stage renal disease (ESRD) patients in the US start dialysis in an inpatient setting, but the characteristics of patients starting dialysis as inpatients, and the association of inpatient hemodialysis transition with mortality remain unclear. METHODS: We examined 48,261 US veterans who transitioned to hemodialysis between October 2007 and September 2011. Associations of inpatient hemodialysis starting with all-cause mortality were examined in Cox proportional hazard models, with adjustments for demographics, comorbidities, vascular access type, pre-dialysis nephrology care and medication use, and last pre-ESRD estimated glomerular filtration rate and hemoglobin...

BACKGROUND: Whether the benefits of phosphorus binders extend to those without end stage renal disease is uncertain. Among a large diverse non-dialysis chronic kidney disease (CKD) population with hyperphosphatemia, we sought to evaluate phosphorus binder use and compare mortality risk between patients prescribed and not prescribed binders. METHODS: A retrospective cohort study within an integrated health system (January 1, 1998 - December 31, 2012) among CKD patients (age ≥18) was performed...

BACKGROUND: Since the introduction of antiretroviral therapy (ART), human immunodeficiency virus (HIV)-infected patients have a drastically improved prognosis but at the same time they are also more affected by non-HIV related complications, such as chronic kidney disease. The objective of our study was to investigate the effect of proteinuria and tenofovir (TDF)-containing ART regimens on the temporal evolution of estimated glomerular filtration rate (eGFR). METHODS: Between April 2008 and October 2012, we enrolled 395 patients with a complete renal evaluation among patients from the ANRS C03 Aquitaine cohort, a prospective hospital-based cohort of HIV-1-infected patients under routine clinical management in southwestern France...

BACKGROUND AND AIMS: Diet and smoking expose the general population to cadmium (Cd), which is a toxic metal that accumulates in the arterial wall. In experimental studies, Cd causes reductions in proliferation of smooth muscle cells and cellular synthesis of procollagen. The aim of this study was to examine whether blood Cd levels, a valid measure of Cd exposure, are associated with increased risk of abdominal aortic aneurysm (AAA). METHODS: All middle-aged men and women enrolled in the Malmö Diet and Cancer study (n = 30 447) were followed from the baseline examination in 1991-1996 through 2009...

Ochratoxin A (OTA), a mycotoxin known for its nephrotoxic and carcinogenic properties, is a worldwide occurring contaminant in a variety of food commodities. Biomonitoring (i.e. analysis in biological fluids) can serve to assess human internal exposure from all consumed foods and beverages. We now determined the concentration of OTA and its metabolite ochratoxin alpha (OTα) in plasma and in urine of two male volunteers with different food habits, in order to assess intra-individual temporal fluctuations and inter-individual differences in their biomarker levels...

Background: Progressively sensitive assays for plasma HIV RNA have led to increased detection of plasma HIV RNA between 20 and 200 copies/ml, known as low level viremia (LLV) when recurrent or persistent, in HIV-infected patients on antiretroviral therapy (ART). The aim of this study was to determine outcomes following initial detection of LLV in an Australian cohort. Methods: A retrospective study using the HIV Service Database (Alfred Hospital) included all patients on ART who recorded plasma HIV RNA 20-200 copies/mL following prior virological suppression (viral load (VL) HIV RNA <20 copies/mL) over 2 years (2010 to 2012), with follow-up to June 2013...

OBJECTIVE: Profoundly increased mortality rates in schizophrenia, largely caused by a higher risk and earlier onset of cardiovascular disease, remain a major challenge. During the human lifespan, advanced glycation end products (AGEs) accumulate, and their concentration is strongly linked to cardiovascular mortality. AGE accumulation can be accelerated by several pathways, including oxidative stress. METHODS: From March 2015 through January 2016, a case-control study including 111 patients with a recent-onset psychosis, 135 controls from a validation cohort, and 286 healthy controls was performed...
