BACKGROUND: Mycotic aneurysm of the thoracic or thoracoabdominal aorta and infection of thoracic or thoracoabdominal aortic grafts are challenging problems with high mortality. In-situ reconstruction with cryopreserved allograft(CPA) avoids placement of prosthetic material in an infected field and avoids suppressive antibiotics or autologous tissue coverage. METHODS: Fifty consecutive patients with infection of a thoracic or thoracoabdominal aortic graft or mycotic aneurysm underwent resection and replacement with CPA from 2006 to 2016...

Transplantation of encapsulated porcine islets is proposed to treat type 1 diabetes. However, envelopment of fibrous tissue and infiltration of immune cells impair islets function and eventually cause implant failure. It is known that hemodialysis using an ethylene vinyl alcohol (EVOH) membrane results in minor tissue responses. Therefore, we hypothesized that using a low adhesive EVOH membrane for encapsulation may prevent host cell accumulation and fibrous capsule formation. In this study, rat islets suspended in chitosan gel were encapsulated in bags made from highly porous EVOH membranes, and their in vitro insulin secretion function as well as in vivo performance were evaluated...

AIM: To explore the association between the sociodemographic factors and the needs of patients undergoing hemodialysis in Taiwan. BACKGROUND: Concomitant discomfort, including physical and mental aspects, affects the patients' quality of life and their willingness to undergo hemodialysis. Maslow's hierarchy of needs is a well-known tool to assess different levels of human needs. METHOD: We conducted a small-scale cross-sectional observational study using a structured needs assessment questionnaire on 159 patients from the Taipei Veterans General Hospital hemodialysis unit...

INTRODUCTION: Restless legs syndrome (RLS) is a common disorder in hemodialysis patients. The present study was conducted to determine the effect of near-infrared (NIR) light therapy given to acupoints on the severity of RLS in patients undergoing hemodialysis. METHODS: This single-blind randomized controlled trial was performed on 60 hemodialysis patients with RLS. Participants who met the inclusion criteria were randomly assigned to an intervention group (n = 30) or a control group (n = 30)...

INTRODUCTION: Calciphylaxis is a rare condition including patchy dermal necrosis that mostly affects chronic hemodialysis patients. The syndrome usually heralds impending death although patients may survive following a set of measures including an adapted dialysis regimen. The present case is a unique patient who recovered from an earlier episode of upper leg calciphylaxis 5 years previously but developed fatal bilateral breast necrosis. PRESENTATION OF CASE: A 69 year old Caucasian woman with a history of atrial fibrillation, hypertension, CVA, hyperparathyroidectomy for secondary hyperparathyroidism and end stage renal disease with hemodialysis recovered in 2012 from extensive symptomatic left upper leg necrosis due to calciphylaxis...

BACKGROUND AND AIMS: Oxidized low-density lipoprotein (oxLDL) causes the development of atherosclerosis and kidney injury. Although circulating oxLDL levels were reportedly increased in type 2 diabetic patients with macroalbuminuria, it remains unclear whether albuminuria or the reduced glomerular filtration rate (GFR) is independently associated with the circulating oxLDL level. This study aimed to elucidate the association between the stage of diabetic nephropathy and serum malondialdehyde-modified LDL (MDA-LDL) and the ratio of MDA-LDL to LDL-cholesterol (MDA-LDL/LDL)...

INTRODUCTION: Malnutrition is prevalent in hemodialysis (HD) patients, and the risk of mortality is strongly correlated with malnutrition. Current methods of nutritional evaluation are mostly subjective, time-consuming, and cumbersome. Creatinine index (CI) and geriatric nutritional risk index (GNRI) are very simple and objective methods to assess the nutritional status of HD patients. The present study compares the performance of CI and GNRI as nutritional risk assessment tools. METHODS: Eighty-eight patients with end-stage renal disease on HD were recruited from a single tertiary center...

INTRODUCTION: Identifying the appropriate modality between hemodialysis (HD) and peritoneal dialysis (PD) is an unresolved issue in polycystic kidney disease (PKD) patients. This study aims to illustrate whether the mortality and survival are different among individuals receiving HD comparing PD. METHODS: We searched PubMed, EMBASE, and China National Knowledge Infrastructure about cohort studies involving PKD patients with end stage renal disease and comparing HD with PD...

Blood-membrane interactions can have a large impact on the performance of hemodialysis membranes, particularly for high flux membranes in which the membrane itself provides very low resistance to solute transport. The objective of this study was to examine the effects of exposure to serum on the solute clearance and convective sieving characteristics of high flux polysulfone (Optiflux F250NR), polyethersulfone (ELISIO-25H), and asymmetric cellulose triacetate (SOLACEA-25H) hemodialyzers using both vitamin B12 and a range of polydisperse dextrans...

Background: Remote ischemic preconditioning (RIPC) is a procedure that generates a brief period of ischemia followed by reperfusion. The role of RIPC in protecting myocardial ischemia during hemodialysis is not yet established. The aim of the study was to evaluate RIPC myocardial protection as evaluated by ultrasensitive I troponin in hemodialysis outpatients. Patients and methods: A double-blind randomized trial with two groups: intervention submitted to RIPC and control group without RIPC...

BACKGROUND: Liposomal amphotericin B (L-AmB) was developed to reduce nephrotoxicity and maximize the therapeutic utility of amphotericin B in the treatment of invasive fungal infections. However, there is little investigation into the safety of L-AmB in patients with several renal functions. Therefore, we retrospectively evaluated the clinical safety of L-AmB among patients with several renal functions. METHODS: We divided patients treated with L-AmB from April 2014 to September 2016 into 4 groups (estimated glomerular filtration rate (eGFR)≥60, 60 > eGFR≥30, eGFR<30 and hemodialysis)...

BACKGROUND: Hemodialysis requires needle insertions every treatment. Needle injury (mechanical or hemodynamic) may cause complications (aneurysms/stenosis) that compromise dialysis delivery requiring interventions. Metal needles have a sharp slanted "V"-shaped cutting tip; plastic cannulae have a dull round tip and four side holes. Preliminary observations demonstrated a difference in intradialytic blood flow images and mean Doppler velocities at cannulation sites between the two devices...

Although gastrointestinal complications are a common feature of patients with chronic kidney disease (CKD), the impact of uremia on bowel motility remains poorly understood. The present study was, therefore, designed to investigate the impact of uremia on gut motility. Kidney failure was induced in mice by chemical nephrectomy using an adenine diet (0.25% w/w ). Gastrointestinal transit time and colon motility were explored in vivo and ex vivo . Colons from control mice were incubated with uremic plasma or uremic toxins (urea, indoxyl-sulfate or p-cresyl-sulfate) at concentrations encountered in patients with end-stage renal disease...

Hemodialysis patients represent a fragile population experiencing many symptoms (e.g., pain, fatigue) that impact their quality of life. The presence and severity of these symptoms are significantly underestimated by health professionals. The purpose of this study is to describe and compare the symptoms perceived by hemodialysis patients versus those detected by nurses and to discuss the possible causes of the disparity observed. A total of 123 patients and 70 nurses working in six hemodialysis centers were included in this study...

BACKGROUND: The association of a higher body mass index (BMI) with better survival is a well-known "obesity paradox" in patients on hemodialysis (HD). However, men and women have different body compositions, which could impact the effect of BMI on mortality. We investigated the effect of gender on the obesity-mortality relationship in Korean patients on HD. METHODS: This study included 2,833 maintenance patients on HD from a multicenter prospective cohort study in Korea (NCT00931970)...
