Oral anticoagulation (OAC) is highly effective preventing stroke and mortality in AF, but withdrawal is common in the elderly, when high bleeding risk and when are difficulties achieving an optimal time in therapeutic range (TTR). We analysed the rate of OAC cessation, predisposing factors to cessation and the relation to clinical outcomes in a large 'real world' cohort of AF patients over a long follow-up period. Consecutive non-valvular AF outpatients clinically stables for six months were recruited. Rates of cardiovascular events, major bleeding and mortality were recorded and related to OAC cessation...

BACKGROUND: Ischemia-reperfusion (I/R) injury is a common cause of patient morbidity and mortality in the perioperative period. Patients undergoing long-lasting, abdominal, and urogenital surgeries with risk factors such as advanced age, peripheral artery disease, diabetes mellitus, renovascular disease, and congestive heart failure are candidates for acute kidney injury (AKI) due to impaired renal perfusion and decreased functional renal reserve. Pharmacological agents with multiple functions and anti-oxidative and anti-inflammation properties may be promising preventative strategies for AKI...

Increased neurohumoral stimulation resulting in excessive sodium avidity and extracellular volume overload are hallmark features of decompensated heart failure. Especially in case of concomitant renal dysfunction, the kidneys often fail to elicit effective natriuresis. While assessment of renal function is generally performed by measuring serum creatinine-a surrogate for glomerular filtration-, this only represents part of the nephron's function. Alterations in tubular sodium handling are at least equally important in the development of volume overload and congestion...

BACKGROUND AND OBJECTIVE: Background and Objective: The motivation of cardiovascular modeling is to understand the haemodynamic and mechanical factors in the diagnosis and treatment of cardiovascular diseases. Several investigations have been carried out by many authors to understand the flow properties of blood in modelling blood flows in the circulatory system. In the present article, the pulsatile flow of Herschel-Bulkley fluid through a bifurcated arterial stenosis in a porous medium with magnetic field and periodic body acceleration has been investigated in view of understanding the role of rheological behaviour of blood, stenotic height, bifurcation angle, magnetic field and porosity of wall in the initiation and proliferation of cardiovascular diseases...

The advent of safe and highly effective direct acting antivirals (DAA) had huge implications for the HCV transplant field and changed our management of both, patients on the waiting list and those with HCV graft reinfection after Liver Transplantation (LT). When treating HCV infection before LT, HCV reinfection of the graft may be prevented in nearly all patients. In addition some candidates show a remarkable clinical improvement and are possibly delisted. Alternatively, HCV infection can be treated post LT either soon after the transplant, taking advantage of the removal of the infected native liver, or at the time of disease recurrence as done in the past...

Oxidative stress aggravates renal fibrosis, a pathway involved in almost all forms of chronic kidney disease (CKD). However, the underlying mechanism involved in the pathogenesis of renal oxidative stress has not been completely elucidated. In this study, we explored the role and mechanism of hypochlorite-modified albumin (HOCl-alb) in mediating oxidative stress and fibrotic response in a remnant-kidney rat model. Five-sixths nephrectomy (5/6 NX) was performed on the rats and then the animals were randomly assigned to intravenous treatment with either vehicle alone, or HOCl-rat serum albumin (RSA) in the presence or absence of SS-31 (administered intraperitoneally)...

BACKGROUND: The mechanistic target of rapamycin (mTOR) inhibitors, everolimus and temsirolimus, have widened therapeutic options to treat renal cell carcinoma (RCC). However, chronic treatment with these inhibitors often induces resistance, leading to therapeutic failure. PURPOSE: The natural compound, sulforaphane (SFN), was added to an everolimus based regime in vitro in the hopes of preventing resistance development. METHODS: A panel of RCC cell lines (A498, Caki-1, KTCTL-26) was treated with everolimus or SFN or with an everolimus-SFN-combination, either short- (24h) or long-term (8 weeks), and cell growth, proliferation, apoptosis, and cell cycle phases were measured...

Dietary management of heart failure (HF) has largely been focused on sodium and fluid restrictions. Although safety and efficacy of these interventions in HF remain unclear, a daily sodium intake between 2000 and 3000 mg/day appears to be safe in these patients. Ongoing clinical research will inform on the safety and efficacy of a more restrictive sodium intake to less than 1500 mg/day. Data shows that routine fluid restriction in HF regardless of symptoms may be unnecessary; however, in patients with signs of congestion, fluid restriction to 2...

BACKGROUND: Anderson-Fabry disease (AFD) is an X-linked recessive inborn error of glycosphingolipid metabolism caused by a deficiency of alpha-galactosidase A. Renal failure, heart and cerebrovascular involvement reduce survival. A Cochrane review provided little evidence on the use of enzyme replacement therapy (ERT). We now complement this review through a linear regression and a pooled analysis of proportions from cohort studies. OBJECTIVES: To evaluate the efficacy and safety of ERT for AFD...

AIMS: Diabetic kidney disease (DKD) is the second leading cause (16.4%) of end-stage renal disease (ESRD) in China. The current study is to assess the cost effectiveness of preventing DKD in patients with newly diagnosed type 2 diabetes (T2DM) from the Chinese health care perspective. METHODS: A lifetime Markov decision model was developed according to the disease course of DKD. Patients with newly diagnosed T2DM might receive treatment according to one of the following three strategies: "do nothing" strategy (control strategy), treatment with angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) (universal strategy), or screening for microalbuminuria followed by ACEI/ARB treatment (screening strategy)...

Gluteal compartment syndrome is a rather rare syndrome often leading to severe sequelae, sepsis, renal failure, and even death due to delayed diagnosis. Establishing early diagnosis is essential to prevent complications associated with ischemia. In this article, we report a 56-year-old male patient who developed gluteal compartment syndrome after incisional hernia and nephrectomy surgery in lateral decubitus position. Gluteal muscle insufficiency developing after fasciotomy and Trendelenburg gait improved within two years...

The diuretics are essential medicaments of antihypertensive therapy. They reduce blood pressure and cardiovascular events optimally. With increasing doses of thiazides and thiazide analogs do not come further powerful effect of reducing blood pressure or cardiovascular mortality and morbidity, but clearly elevate the side effects. Because of it, the minimum effective dose level and the fixed-dose combination therapy should be preferred. The use these drugs leads to especially positive outcome in elder patients, isolated systolic hypertension, heart failure, after stroke and in black population...

REVIEW
Nai-Ching Chen, Chih-Yang Hsu, Chien-Liang Chen
The high prevalence of arterial calcification in end-stage renal disease (ESRD) is far beyond the explanation by common cardiovascular risk factors such as aging, diabetes, hypertension, and dyslipidemia. The finding relies on the fact that vascular and valvular calcifications are predictors of cardiovascular diseases and mortality in persons with chronic renal failure. In addition to traditional cardiovascular risk factors such as diabetes mellitus and blood pressure control, other ESRD-related risks such as phosphate retention, excess calcium, and prolonged dialysis time also contribute to the development of vascular calcification...

Excess of uric acid is mainly treated with xanthine oxidase (XO) inhibitors, also called uricostatics because they block the conversion of hypoxanthine and xanthine into urate. Normally, accumulation of upstream metabolites is prevented by the hypoxanthine-guanine phosphoribosyltransferase (HPRT) enzyme. The recycling pathway, however, is impaired in the presence of HPRT deficiency, as observed in Lesch-Nyhan disease. To gain insights into the consequences of purine accumulation with HPRT deficiency, we investigated the effects of the XO inhibitor allopurinol in Hprt-lacking (HPRT-/-) mice...

Diabetic kidney disease is the leading cause of end-stage renal disease, a significant contributor to cardiovascular (CV) disease, responsible for much of the morbidity and mortality in patients with type 2 diabetes (T2DM). Strategies to slow or prevent the onset and progression of diabetic kidney disease are critical for effectively managing T2DM and reducing CV risk. Sodium-glucose cotransporter 2 (SGLT2) inhibitors are effective antidiabetic agents, which may provide nephroprotective and CV protective effects...

Several multivariate risk score models were developed to predict prognosis of patients with heart failure (HF). We compared 3 models with regard to prediction of mortality in patients with HF who received an implantable defibrillator (ICD) or a cardiac resynchronization therapy defibrillator (CRT-D), as primary prevention of sudden death. The study cohort consisted of 823 patients (ICD = 410; CRT-D = 413). The evaluated models were the Seattle Heart Failure Model (SHFM), the Multicenter Automatic Defibrillator Implantation Trial II (MADIT II) score, and an adjusted Charlson Comorbidity Index (aCCI)...

The shortage of organs for transplant is a universal problem. The World Health Organization is urging every nation to seek self-sufficiency regarding their organ procurement program. Reaching self-sufficiency inevitably requires the provision of a well-developed deceased-donor organ procurement program. Most countries represented by the Middle East Society for Organ Transplantation still rely on living-donor organ donations. Some of these countries have been relatively successful in promoting deceased-donor donation as well...

One of the most important pathological consequences of renal ischemia/reperfusion (I/R) is kidney malfunctioning. I/R leads to oxidative stress, which affects not only nephron cells but also cells of the vascular wall, especially endothelium, resulting in its damage. Assessment of endothelial damage, its role in pathological changes in organ functioning, and approaches to normalization of endothelial and renal functions are vital problems that need to be resolved. The goal of this study was to examine functional and morphological impairments occurring in the endothelium of renal vessels after I/R and to explore the possibility of alleviation of the severity of these changes using mitochondria-targeted antioxidant 10-(6'-plastoquinonyl)decylrhodamine 19 (SkQR1)...
