The association of overhydration with megafistulas in hemodialysis patients.

The association of overhydration with megafistulas in hemodialysis patients. Ren Fail. 2019 Nov;41(1):440-445 Authors: Tapolyai M, Faludi M, Berta K, Forró M, Zsom L, Pethő ÁG, Rosivall L, Fülöp T Abstract Objectives: Diffuse enlargements of arteriovenous dialysis fistulas customarily attributed to either excessive arterial inflow or central outflow stenosis. The relationship between volume status and clinically enlarged (arteriovenous) fistula (CEF) formation in end-stage renal disease (ESRD) patients is not well understood. Methods: We assessed the pre-dialysis bioimpedance spectroscopy-measured percentage of overhydration (OH%) in 13 prevalent dialysis patients with CEF development and negative angiography and compared the results with those of 52 control dialysis patients (CONTR). All patients were prevalent ESRD patients receiving thrice-weekly maintenance hemodiafiltration at an academic outpatient dialysis unit. Results: 10/13 CEF patients had OH% ≥15% as compared to 20/52 control patients (Chi square p: .02). The degree of OH% was 20.2 ± 7.4% among the CEF vs. 14.4 ± 7.1% in the control group (Student's t-test p: .01), representing 4.2 ± 3.2 vs. 2.8 ± 1.6 L of excess fluid pre-dialysis (p: .03). Patients with CEF development took an average of 1.7 ± 1.4 vs. 0.8 ± 0.8 (p: .002) antihyperten...

AbstractBackgroundMany of the patients who are undergoing Coronary Artery Bypass Graft have diabetes mellitus or metabolic syndrome and are at risk for hyperglycemia events.ObjectiveThe present study aimed to compare conventional glucose control with adjusted tight control in patients undergoing on-pump CABG.MethodsThis double –blind randomized clinical trial study was conducted in Shiraz, Iran, from September 2017–March 2018. Two consecutive groups of 75 patients undergoing elective on- pump coronary artery bypass graft surgery.InterventionThe patients were divided into adjusted tight control of the blood gluc...

Authors: Lin WC, Tsai JP, Lai YH, Lin YL, Kuo CH, Wang CH, Hsu BG Abstract Osteoprotegerin (OPG) is a potential biomarker of cardiovascular disease complications and severity. Peripheral arterial disease (PAD) is associated with an increased risk of death in patients on peritoneal dialysis (PD). Therefore, this study aimed to evaluate the relationship between serum OPG levels and PAD by measuring the ankle-brachial index (ABI) of patients on PD. A commercial enzyme-linked immunosorbent assay kit was used to measure OPG values. Left or right ABI values of

Abstract Diabetic nephropathy as a deleterious complication of diabetes mellitus and an important cause of end-stage renal failure is characterized by changes in the molecular and cellular levels. Cell-cell communication via the gap and tight junctions are involved in the pathogenesis of diseases such as diabetes and kidney failure. Studying cell junctions including gap junctions, tight junctions, and anchoring junctions within the nephron can be used as an early sign of diabetic nephropathy. Furthermore, cell junctions may be an upcoming target by pharmacological methods to improve treatments of diabetic nephropa...

This study aims to understand the progression of two chronic diseases in the Australian health context. It specifically focuses on the comorbidity progression of cardiovascular disease (CVD) in patients with type 2 diabetes mellitus (T2DM), as the prevalence of these chronic diseases in Australians is high. A research framework is proposed to understand and represent the progression of CVD in patients with T2DM using graph theory and social network analysis techniques. Two study cohorts (i.e., patients with both T2DM and CVD and patients with only T2DM) were selected from an administrative dataset obtained from an Australi...

SUMMARY Type 2 diabetes mellitus is an important public health problem, with a significant impact on cardiovascular morbidity and mortality and an important risk factor for chronic kidney disease. Various hypoglycemic therapies have proved to be beneficial to clinical outcomes, while others have failed to provide an improvement in cardiovascular and renal failure, only reducing blood glucose levels. Recently, sodium-glucose cotransporter-2 (SGLT2) inhibitors, represented by the empagliflozin, dapagliflozin, and canagliflozin, have been showing satisfactory and strong results in several clinical trials, especially regarding...

This study aims to compare the survival and the risk of heart failure, chronic obstructive pulmonary disease, diabetes mellitus, hypoglycemia, and renal failure hospitalizations in geriatric patients that were exposed to carvedilol or metoprolol. Danish administrative healthcare registers were used as data sources. Patients aged ≥ 65 and having heart failure, chronic obstructive pulmonary disease, and diabetes mellitus were followed for 1 year from the date of the first beta-blocker prescription redemption.

Abstract Treat to target is defined by a process defining a level of a relevant outcome of the disease to be reached in order to prevent subsequent disability The benefit of a Treat to Target strategy has been clearly demonstrated in chronic diseases such as diabetes and hypertension. A better knowledge of the natural history of chronic inflammatory rheumatic diseases including axial spondyloarthritis has emphasized the deleterious long term effect of a sustained inflammation, usually evaluated by disease activity markers. The Treat to Treat strategy in axial spondyloarthritis has emerged since the possibility of ...

Conclusion Despite similar dialysis intensity, the composite neonatal morbidity was higher in women with renal failure caused by diabetes or lupus compared with other etiologies. Our findings suggest that pregnancy outcome in women receiving dialysis is dependent on both the intensity of dialysis as well as the etiology of renal failure.

We describe the first case worldwide of capillary hemangioma that was a true vascular tumor arising from the lesser omentum. Although capillary hemangioma arising from the lesser omentum is extremely rare, it should be considered in the differential diagnosis of patients presenting with a highly enhanced lesser omental tumor, and laparoscopy can be safely applied for the excision of this tumor.
