<b><i>Background:</i></b> Death with graft function remains an important cause of loss among kidney transplant recipients (KTRs). Little is known about the trend specific causes death in KTRs recent years. <b><i>Methods:</i></b> We analyzed United States Renal Data System data (1996–2014) to determine 1- and 10-year all-cause cause-specific mortality adult who died a functioning allograft. also studied trends various mortality....

Abstract Background Anemia is associated with adverse outcomes in those chronic kidney disease (CKD). We examined the association of absolute and functional iron deficiency anemia (IDA) (cardiovascular hospitalization, dialysis mortality) nondialysis-dependent CKD. Methods Nondialysis-dependent CKD patients followed US Veterans Administration hemoglobin level measured within 90 days date second estimated glomerular filtration rate <60 mL/min/1.73 m2 were included. Logistic regression,...

The 4-quadrant forceps biopsy (FB) protocol for identifying Barrett's esophagus (BE) and esophageal dysplasia (ED) suffers from poor sensitivity due to significant sampling error. We investigated the benefit of wide-area transepithelial with 3-dimensional computer-assisted analysis (WATS) used adjunctively combination random targeted FB in detection ED, as a secondary outcome, BE. In this multicenter prospective trial, community endoscopists at 21 sites utilized WATS an adjunct both patients...

Background and objectives The etiology of chronic kidney disease unclear etiology, also known as Mesoamerican nephropathy, remains unclear. We investigated potential etiologies for nephropathy in an immigrant dialysis population. Design, setting, participants, & measurements Migrants with failure ( n =52) were identified by exclusion causes compared using a cross-sectional survey demographically similar patients from other =63) age/sex/place origin–matched healthy participants =16)....

Coronary-cameral fistulas are rare congenital malformations, often incidentally found during cardiac catheterizations. The majority of these in nature but can be acquired secondary to trauma or invasive procedures. These most commonly originate the right coronary artery and terminate into ventricle least frequently drain left ventricle. Depending upon their size location, coronary-cameral lead congestive heart failure, myocardial infarction, bacterial endocarditis. We describe a case...

Marijuana is the most widely abused “recreational” substance in United States, with highest prevalence young adults. It reported to cause ischemic strokes, hepatitis, anxiety, and psychosis. Although it associated dose dependent tachycardia can lead coronary vasospasm, has not been directly related acute myocardial infarction (AMI). induced vasospasm result endothelial denudation at site of a vulnerable atherosclerotic plaque response hemodynamic stressors, potentially causing an AMI. Spice...

In 2011, inclusion of injectable medications into an expanded ESKD payment bundle prompted concerns that dialysis facilities facing higher costs might close, disrupting care delivery and access to care. Whether this policy change influenced facility closures is unknown.To examine whether increased after 2011 factors influencing changed, we analyzed US Renal Data System registry data identify all patients receiving in-center hemodialysis from 2006 through 2015 track closures. We used...

Employment is associated with an improved sense of well-being and quality life in patients kidney disease. Earlier nephrology referral longer duration pre-end-stage disease (ESKD) care are health outcomes advanced who initiate dialysis. It unknown if pre-ESKD helps stay employed leading up to dialysis initiation.We used the US ESKD registry identify adults aged 18-54 years initiated between 2007 2014. Analyses were restricted reported being 6 months prior ESKD. We multivariable regression...

Familial hypercholesterolemia (FH) is a globally underdiagnosed genetic condition associated with premature cardiovascular death. The etiology data on Arab FH patients scarce. Therefore, this study aimed to identify the basis of in Saudi family using whole exome sequencing (WES) and multidimensional bioinformatic analysis. Our WES findings revealed rare heterozygous gain-of-function variant (R496W) exon 9 PCSK9 gene as causal factor for family. This was absent healthy relatives proband 200...
