Coronary artery disease is the leading cause of morbidity and mortality worldwide, especially in developed countries, with an increasing incidence in developing countries. Despite the ad-vances in cardiology, there are yet many unanswered questions about the natural history of cor-onary atherosclerosis. However, it has not been fully explained why some coronary artery plaques remain quiescent over time, whereas others evolve to a high-risk, "vulnerable" plaque with a predisposition to destabilize and induce a cardiac event...

INTRODUCTION: A right aortic arch and agenesis of internal carotid artery (ICA) are both extremely rare vascular devel- opment anomalies. Etiology of the both anomalies might be associated with the abnormal regression of the dorsal aorta. Most cases of ICA are asymptomatic due to sufficient collateral circulation and it is usually an incident finding on head and neck imaging by color Doppler ultrasonography, computed tomography (CT) or magnetic resonance imaging (MRI). ICA agenesis has a significant association - 24-67% - with intracranial aneurysms and their early detection can spare the patient serious complications...

End-stage renal failure is the reason for complications in many systems and organs, and the applied pharmacotherapy often causes the deepening of already existing pathologies within the oral cavity, such as: caries, periodontal diseases, mucosal lesions or reduced saliva secretion. Reduced saliva secretion results in an increased accumulation of dental plaque, its mineralization and prolonged retention, which leads to the development of gingival and periodontal inflammation. There is some evidence that chronic kidney diseases are influenced by periodontal health...

BACKGROUND: The chronic kidney disease, blood hypertension and diabetes are recognized as civilization diseases that affect more and more people. The probability of encountering a patient suffering from these diseases is increasing. As such, it appears crucial to better understand the specific dental needs of such groups of patients. The aim of the work was to assess the oral hygiene status and the needs of patients suffering from the end-stage chronic kidney disease, arterial hypertension or/and diabetes...

Background: Secondary hyperparathyroidism (SHPT) is frequent in haemodialysis (HD) patients. Oral cinacalcet-hydrochloride (HCl) decreases parathyroid hormone (PTH); however, real-life PTH data, according to Kidney Disease: Improving Global Outcomes (KDIGO) guidelines, are still lacking. Our goal is to assess the percentage of cinacalcet-HCl-treated HD patients with controlled SHPT (PTH <9× upper limit of the normal range) after 12 months (M12) of treatment. Methods: This is a retrospective observational study in HD patients with SHPT treated by cinacalcet-HCl between 2005 and 2015 and dialysed in seven French HD centres using the same database (Hemodial™)...

BACKGROUND: Persistent left superior vena cava (PLSVC) is a common vena cava malformation, and drains blood into the right atrium via the dilated coronary sinus in most cases. It is usually asymptomatic and detected incidentally during invasive procedures or imaging. Whether the hemodialysis catheters can be placed in PLSVC is still controversial now (Stylianou et al. Hemodial Int 11:42-45, 2007). CASE PRESENTATION: Here we report a rare case of catheterization through PLSVC in an end-stage renal disease (ESRD) male patient whose PLSVC connected with pulmonary vein with insufficient blood flow eventually...

Intracranial aneurysms (IA) are a huge threat to human health, with a global incidence rate of 0.65-8.4%. Although the microsurgical and interventional techniques have made profound progression in treating IA, the relatively high rate of complications and recurrence are still not satisfactory. Thus, there is a need to elucidate its molecular mechanism. Numerous studies have identified the close relationship between hemodynamic-induced inflammation and development of IA. Indeed, the dysfunction of endothelial cells, smooth muscle cells, macrophages and lymphocytes, as well as their secreted cytokines, collectively contribute to the formation, growth and rupture of IA...

OBJECTIVE: This study aimed to investigate the effects ofguided imagery on state and trait anxiety and sleep quality among hemodial ysis patients. DESIGN: This was a randomized controlled trial. A total of seventy hemodialysis patients were assigned through block randomization to either an intervention group to receive guided imagery or a control group to receive routine care services. SETTING: The study was performed in the hemodialysis unit of Akhavan teaching hospital, Kashan, Iran...

Introduction: This study has been performed for the purpose of researching the complications occurred at patients who took metformin overdose in an attempt to suicide. None of the patients has the diagnosis of diabetes mellitus and never used metformin. Materials and Methods: This retrospective cross-sectional study was carried out with 21 patients who has neither diagnosed diabetes mellitus nor taken metformin for suicide before. Results: It was observed that there is a moderate, negative (r = -0...

BACKGROUND: Vascular calcification is one of the risk factors for arterial stiffness in patients with chronic kidney disease. We hypothesized that a mismatch between elastic and muscular arteries, represented as pulse wave velocity (PWV) ratio, could depict the extent of vascular calcification in end-stage renal disease. We also aimed to compare the predictive PWV ratio value to other factors possibly related to vascular calcification in dialysis population. METHODS: In this cross-sectional study, in 60 chronic dialysis patients without previous cerebrovascular events, cardiovascular disease and events or clinically evident peripheral artery disease (ankle-brachial index >0...

Changes in BOLD signals are sensitive to the regional blood content associated with the vasculature, which is known as V0 in hemodynamic models. In previous studies involving dynamic causal modeling (DCM) which embodies the hemodynamic model to invert the functional magnetic resonance imaging signals into neuronal activity, V0 was arbitrarily set to a physiolog-ically plausible value to overcome the ill-posedness of the inverse problem. It is interesting to investigate how the V0 value influences DCM. In this study we addressed this issue by using both synthetic and real experiments...

BACKGROUND: Some studies have shown an increased relative risk of death for patients with higher levels of Kt/V, which may be associated with marked malnutrition. OBJECTIVE: The aim of this study was to investigate the relationship between the target dose for hemodialysis adequacy, as measured by Kt/V, and various nutritional parameters in hemodialysis patients. DESIGN: Cross-sectional. SETTINGS: Sakarya University Faculty of Medicine, Turkey between February 2014 and March 2014...

Intradialytic hypotension is the most common complication associated with hemodialysis. We describe a case of severe intradialytic hypotension during routine chronic dialysis, the presenting symptom of hypocalcemia due to a procedural error involving a zero calcium liquid acid dialysate concentrate. Although human factors were the root cause of this event, we discuss physical and procedural controls that may help to minimize the risk of human error. Citrate anticoagulation for renal replacement therapy is increasingly used, particularly in acute kidney injury...

OBJECTIVE: Blood pressure (BP) variability correlates with cardio-vascular disease as BP level itself. There is not known easy way to evaluate the BP variability in clinic.To evaluate the usefulness of maximum-minimum difference (MMD) of BP in a month compared to standard deviation (SD), as an index of BP variability. DESIGN AND METHOD: Study-1: Twelve patients (age 65.9 ± 12.1 y/o) were enrolled. Measurements of home systolic (S) BP were required in the morning...

When a patient aggressively receives treatment and looks forward to returning home, the prolonging of meaningful life is difficult, even with medical treatment. It is typically very challenging at this juncture for the members of the medical team to fully disclose to the patient the true extent of his / her condition and to recommend the withdrawal of life-support medical treatment. This article describes a nursing care experience with a renal cell carcinoma patient with subcutaneous metastasis. Her pain was induced by an edema and subcutaneous tumor in her lower limbs, which diminished the effectiveness of hemodialysis...

BACKGROUND: The therapeutic role of L-carnitine (LC) on the anemia of chronic hemodialized patients is still controversial. In order to clarify the long-term effects of LC administration on renal anemia, an open, observational 12-month study was performed. METHODS: Twenty stable outpatients undergoing hemodialysis were administered LC 900 mg p.o. daily for 12 months. The recombinant human erythropoietin (rHuEPO) dose was adjusted monthly when necessary to maintain the target hemoglobin (Hb) levels...

The expression of proinflammatory cytokines/chemokines has been reported in in vitro/ex vivo settings of chronic venous insufficiency (CVI), but the identification of circulating mediators that might be associated with altered hemodynamic forces or might represent innovative biomarkers is still missing. In this study, the circulating levels of 31 cytokines/chemokines involved in inflammatory/angiogenic processes were analysed in (i) CVI patients at baseline before surgical hemody namic correction, (ii) healthy subjects, and (iii) CVI patients after surgery...

BACKGROUND/METHODS: The association between nutritional status, antioxidant human paraoxonase-1 (PON1) activity and low grade inflammation in hemodialized (HD) patients with chronic kidney disease (CKD) is unclear. The aim of this study was to determine PON1 paraoxonase and lactonase activities, ADMA, adiponectin and leptin concentrations, and to clarify the relationship between paraoxonase activity and a set of cardiovascular risk factors in malnourished, normal weight and obese HD patients; 114 HD patients with end-stage renal failure were enrolled...

UNLABELLED: Infectious complications associated with vascular access are a well known cause of increased morbidity and mortality in hemodialysis patients. The aim of the study was to evaluate the incidence of hemodialysis vascular access infections and patients survival in the group of maintenance hemodialysis patients during a one year observation period. The study group consisted of 213 patients (126 male, 87 female; aged 57.4 +/- 14.9 years being on renal replacement therapy for 54 months; range: 2 to 384 months) treated by maintenance hemodialysis at the Nephrology Department of the University Hospital...

Pruritus is an alarming symptom in patients with end-stage renal disease (ESRD) accompanied by sleep disturbances and physical and mental disorders. Although its prevalence is very high among hemodialysis patients (90%), its etiology and its successful treatment have been unconfirmed (Melo N, Elias R, Castro M, Romao G, Abensur H. Pruritus in hemodialysis patients: The problem still remains. Hemodial Int. 2009;13:38-42.). Common pruritus etiologies, such as high parathyroid hormone levels, dialysis inadequacy, and iron deficiency are matters of conflict...
