BACKGROUND: Little is known about the burden of recurrent out-of-hospital cardiac arrest (OHCA) episodes in initial survivors of OHCA. We sought to investigate the frequency of recurrent OHCA, describe time-to-event trends, and establish baseline predictors of occurrence. METHODS: Between January 2000 and June 2015, we included consecutive OHCA survivors to hospital discharge from the Victorian Ambulance Cardiac Arrest Registry. Patient identifiers were used to match index and recurrent episodes of OHCA, and death records from a government database...

OBJECTIVE: Preoperative anemia in elderly patients undergoing surgery is prevalent and associated with adverse events; however, the interaction with other risk factors in patients with chronic limb-threatening ischemia (CLTI) is not well described. The purpose of this study was to assess the association between lower hematocrit (HCT) levels on admission and postoperative outcomes after infrainguinal bypass surgery. METHODS: Patients with CLTI undergoing nonemergent infrainguinal bypass were identified in the targeted vascular module of National Surgical Quality Improvement Program (NSQIP; 2011-2014)...

When estimating the effect of an exposure on a time-to-event type of outcome, one can focus on the baseline exposure or the time-updated exposures. Cox regression models can be used in both situations. When time-dependent confounding exists, the Cox model with time-updated covariates may produce biased effect estimates. Marginal structural models, estimated through inverse-probability weighting, were developed to appropriately adjust for time-dependent confounding. We review the concept of time-dependent confounding and illustrate the process of inverse-probability weighting...

BACKGROUND: Adequate muscle relaxation is important for ensuring optimal conditions for intubation. Although acceleromyography of the adductor pollicis muscle is commonly used to assess conditions for intubation, we hypothesized that acceleromyography of the trapezius is more indicative of optimal intubating conditions. The primary outcome was the difference between both measurement sites with regard to prediction of good or acceptable intubating conditions. METHODS: Neuromuscular blockade after injection of rocuronium 0...

BACKGROUND: Weight gain early after transplant is a risk factor for posttransplant metabolic syndrome (PTMS), cardiovascular events, and renal insufficiency. The impact of mTOR inhibition on posttransplant weight gain and the development of PTMS components postliver transplantation were examined in a randomized, controlled study. METHODS: Following a run-in period, patients (N = 719) were randomized at 30±5 days posttransplant in a 1:1:1 ratio to 3 treatment groups: (i) everolimus (EVR) + reduced tacrolimus (TAC)(n=245); (ii) TAC control (n=243) or (iii) TAC elimination (n=231)...

Hyponatremia is associated with bone demineralization. We hypothesized that, during hyponatremia, calciuria and calcium balance depend on volemic status. We evaluated calciuria in patients with hyponatremia, secondary to SIAD or hypovolemia. Patients with SIAD exhibited a volemic expansion that was associated with hypercalciuria. Calciuria was proportional to markers of volemia. INTRODUCTION: Chronic mild hyponatremia has been associated with bone demineralization of unknown mechanisms...

STUDY OBJECTIVE: Computed tomography (CT) is an important imaging modality used in the diagnosis of a variety of disorders. Imaging quality may be improved if intravenous contrast is added, but there is a concern for potential renal injury. Our goal is to perform a meta-analysis to compare the risk of acute kidney injury, need for renal replacement, and total mortality after contrast-enhanced CT versus noncontrast CT. METHODS: We searched MEDLINE (PubMed), the Cochrane Library, CINAHL, Web of Science, ProQuest, and Academic Search Premier for relevant articles...

It is acknowledged that contrast-induced nephropathy (CIN) is a common cause of acute renal insufficiency after cardiac catheterization and affects mortality and morbidity. To date, it is unknown whether oral N-acetylcysteine (NAC) is able to prevent contrast-induced nephropathy (CIN) in patients undergoing coronary angioplasty. A meta-analysis of randomized controlled trials was performed to assess the effects of NAC in the prevention of CIN in patients following coronary angioplasty. A total of 19 studies published prior to January 2015 that investigated the efficacy of oral NAC for the prevention of CIN were collected from Medline, Cochrane and Embase databases and conference proceedings from cardiology and nephrology meetings...

BACKGROUND: Heart transplantation (HTx) is the preferred treatment for patients with end-stage heart failure and has been successful for >30 y. The clinical course of recipients at the extreme of age is unknown. We reviewed our experience to determine the overall health and prevalence of Tx-related medical problems for recipients in their ninth decade. METHODS: We reviewed the UCTP experience from 1985 to present to identify patients who survived into their 80s and matched (1:1) with other recipients for gender and age at HTx, but did not survive to ≥80 y...

We report a case of allergic acute tubulointerstitial nephritis (TIN) induced by acetaminophen in a 48-year-old Japanese man with no past medical history. Two days after receiving the non-steroidal anti-inflammatory drug (NSAID) loxoprofen for left shoulder pain, he developed cold symptoms such as fever and sore throat. He then took a 300 mg dose of acetaminophen three times a day and a 100 mg dose of minocycline hydrochloride twice a day for 7 days. Because there was no improvement in his symptoms, he consulted a local clinic again, where blood tests revealed renal insufficiency, and he was, then, referred to our hospital for evaluation of kidney function...

Functional tricuspid valve (TV) regurgitation secondary to left heart disease (e.g. mitral insufficiency and stenosis) is observed in 75% of the patients with TV regurgitation and is thus the most common etiology; therefore, the majority of patients who require TV surgery, undergo concomitant mitral and/or aortic valve surgery. Uncorrected moderate and severe TV regurgitation may persist or even worsen after mitral valve surgery, leading to progressive heart failure and death. Patients with moderate to severe TV regurgitation show a 3-year survival rate of 40%...

Inferior vena cava (IVC) anomalies were rare and usually asymptomatic. Among these, anomalies absence of infra-renal IVC is the rarest anomaly. Absence of infra-renal IVC may present with symptoms of venous insufficiency and idiopathic deep vein thrombosis. Contrast enhanced CT and MRI abdomen play crucial role in diagnosing these anomalies. These patients can be managed conservatively or by venous bypass. Identification of these anomalies is important to avoid surgeries for varicose veins.

Autosomal recessive polycystic kidney disease (ARPKD) is an important childhood nephropathy, occurring 1 in 20,000 live births. The major clinical phenotypes are expressed in the kidney with dilatation of the collecting ducts, systemic hypertension, and progressive renal insufficiency, and in the liver with biliary dysgenesis, portal tract fibrosis, and portal hypertension. The systemic hypertension has been attributed to enhanced distal sodium reabsorption in the kidney, the structural defects have been ascribed to altered cellular morphology, and fibrosis to increased TGF-β signaling in the kidney and biliary tract, respectively...

INTRODUCTION: Hyperuricemia is common in approximately 50% of patients with kidney failure due to decreased uric acid excretion, and it has been recently known as an independent factor in the progression of renal insufficiency. Allopurinol inhibits the production of uric acid. The aim of this study was to evaluate the effect of allopurinol on chronic kidney disease progression. MATERIALS AND METHODS: In a clinical trial, patients with stages 3 and 4 of chronic kidney disease were divided into two groups to receive allopurinol, 100 mg, daily and placebo for 12 months...

BACKGROUND: Renal insufficiency is one of the most serious renal diseases. Early diagnosis plays an essential role. Serum creatinine as a marker has had priority so far. The use of cystatin C for estimation of glomerular filtration rate has been recommended recently. There is a set of formulae which consolidates serum values of both creatinine and cystatin C. The study focuses on different formulae and their estimation for the purpose of better, faster, and more accurate diagnosis of renal insufficiency...

In patients with chronic kidney disease (CKD), clinical interest often centers on determining treatments and exposures that are causally related to renal progression. Analyses of longitudinal clinical data in this population are often complicated by clinical competing events, such as end-stage renal disease (ESRD) and death, and time-dependent confounding, where patient factors that are predictive of later exposures and outcomes are affected by past exposures. We developed multistate marginal structural models (MS-MSMs) to assess the effect of time-varying systolic blood pressure on disease progression in subjects with CKD...
