Practice of dialysis access interventional nephrology procedures in the Asia-Pacific region: Getting lay of the land.

AIM: This cross-sectional survey aimed to determine the prevalence of Interventional Nephrology (IN) practice amongst nephrologists in the Asia-Pacific Region (APR), specifically related to dialysis access (DA). METHODS: The Association of VA and intervenTionAl Renal physicians (AVATAR) Foundation from India conducted a multinational online survey amongst nephrologists from the Asia-Pacific to determine the practice of IN in the planning, creation, and management of dialysis access. The treatment modalities, manpower and equipment availability, monthly cost of treatment, specifics of dialysis access interventions, and challenges in the training and practice of IN by nephrologists were included in the survey. RESULTS: Twenty-one countries from the APR participated in the survey. Nephrologists from 18 (85.7%) countries reported performing at least one of the basic dialysis access-related IN procedures, primarily the placement of non-tunnelled central catheters (n-TCC; 71.5%). Only 10 countries (47.6%) reported having an average of <4% of nephrologists performing any of the advanced IN access procedures, the most common being the placement of a peritoneal dialysis (PD) catheter (20%). Lack of formal training (57.14%), time (42.8%), incentive (38%), institutional support (38%), medico-legal protection (28.6%), and prohibitive cost (23.8%) were the main challenges to practice IN. The primary obstacles to implementing the IN training were a lack of funding and skilled personnel. CONCLUSION: The practice of dialysis access-related IN in APR is inadequate, mostly due to a lack of training, backup support, and economic constraints, whereas training in access-related IN is constrained by a lack of a skilled workforce and finances.

Quality characteristics of buckwheat (Fagopyrum esculentum) based nutritious ready-to-eat extruded baked snack.

The study aimed to utilize buckwheat and bread waste to develop ready to eat snack with reduced fat, enriched protein, dietary fiber and minerals. Base flour constituting of buckwheat flour (BF) and rice flour in the ratio of 90:10 was replaced with bread powder (BP) at varying levels (0-80%). The gelatinization temperature of base flour was 67 °C and it decreased with increasing amount of BF. The breaking strength of the extruded snack with varying amount of BP, fat and chilli powder were in the range between 3.46-2.04 N, 1.56-1.26 N and 1.5-1.89 N respectively. Physical and sensory analyses indicate that 40% BP, 8% fat and 1% chilli powder were optimum to obtain extruded snack with desirable characteristics. The ready to eat snack contained 10.64%, 15.33% and 7.45% of fat, protein and total dietary fiber respectively. Minerals present were 169 mg/100 g of magnesium, 46 mg/100 g of calcium, 4.5 mg/100 g of iron and 3.46 mg/100 g of zinc. Bread waste can thus be utilized in producing a healthy ready to eat snack.

Emphysematous pyelonephritis: experience at a tertiary care hospital in Bangladesh.

BACKGROUND: Emphysematous pyelonephritis (EPN) is a necrotizing infection of the renal parenchyma, collecting system and/or perinephric tissues, characterized by gas accumulation. We describe clinical, laboratory and imaging characteristics and in-hospital outcomes of patients with EPN. METHODS: This retrospective observational study was carried out at BIRDEM General Hospital, Dhaka, Bangladesh between 2014 and 2020. RESULTS: We followed 20 patients (mean age 49.4 years; females 70%). Risk factors for EPN were diabetes mellitus (in 100%) and renal stones (in 10%). Fever, loin pain, vomiting and dysuria were common. Complications included acute kidney injury (AKI, 70%; mostly stage 1, 78.6%), hyponatraemia (55%) and bacteraemia (15%). Escherichia coli was the most common (60%) urinary isolate. Most patients (80%) had class 2 EPN, with 15% class 3B and 5% class 3A. Besides medical management, four (20%) required surgery (nephrectomy in 3). Nephrectomised patients had a higher radiological class (p = 0.032) and incidence of AKI (p = 0.034). No deaths occurred. CONCLUSION: EPN occurred predominantly in female diabetic patients, who presented with fever, loin pain, vomiting and dysuria. Two-thirds of patients had AKI and one-fifth required surgery, and there were no deaths.

Class 4 emphysematous pyelonephritis with emphysematous cystitis: report of a rare case from Bangladesh.

Emphysematous pyelonephritis is a rare, severe form of necrotising infection of the kidneys and peri-nephric tissues with gas accumulation, occurring predominantly among patients with diabetes mellitus. Computed tomography scan can identify the distribution of gas in the affected reno-ureteral units and so establish and classify the diagnosis. We report a case of class 4 emphysematous pyelonephritis with emphysematous cystitis, occurring in a young Bangladeshi male, who presented with features of upper urinary tract infection. He had a background history of fibro-calculous pancreatic diabetes and chronic kidney disease. Imaging also revealed renal stones. He responded to conservative treatment.

Experience Managing Adult Patients on Continuous Ambulatory Peritoneal Dialysis in Bangladesh.

Continuous ambulatory peritoneal dialysis (CAPD) is becoming increasingly known to the patients of Bangladesh, and patient numbers are increasing. Here, we report our experience and clinical outcomes in this field.Our analysis included all CAPD patients managed in a tertiary care hospital in Bangladesh between 2003 and 2015. All patients received a Tenckhoff double-cuff catheter by mini-laparotomy, and twin bags were used in most patients. In acute cases, regular exchanges were started manually with small-volume dwells the same or the next day.During the study period, 500 patients (mean age: 62 ± 18 years; 62% men; 86% percent with diabetes) were managed. Selection of CAPD was made by choice (47%) or for hemodynamic instability (32%), remote residence (17%), or poor vascular access (4%). Total duration of follow-up was 9364 patient-months (range: 1 - 78 months). The peritonitis rate was 1 episode in 30 patient-months. Fewer than 5% of patients required catheter removal. Similarly, the percentages of catheter tip migration and fluid leak were at the lower end. Patient survival was 68%, 48%, 38%, 22%, and 8% at 1, 2, 3, 5, and 7 years. Deaths were mostly attributable to vascular events.In a population with predominantly diabetic patients, CAPD was shown to be a viable mode of renal replacement therapy. The rates of peritonitis and catheter-related complications were low. Survival in the initial years can be considered acceptable.

Purtscher's retinopathy and renal cortical necrosis: two rare vaso-occlusive complications in a patient with acute pancreatitis: a case report.

BACKGROUND: Purtscher's retinopathy and renal cortical necrosis are two rare vaso-occlusive complications of acute pancreatitis. Purtscher's retinopathy causes sudden impairment of vision, which was first reported in a patient with head trauma. Subsequently, it was also reported as a complication of acute pancreatitis and few other clinical conditions. Acute pancreatitis also rarely causes renal cortical necrosis leading to acute kidney injury. However, the simultaneous presence of both complications is rarely reported. CASE PRESENTATION: A 20-year-old Bengali man presented to our hospital with a history of acute upper abdominal pain, vomiting, anuria, and disorientation. He was ultimately found to have bilateral complete blindness due to Purtscher's retinopathy and acute kidney injury due to renal cortical necrosis, as sequelae of acute pancreatitis. He became dialysis-dependent, his vision did not recover, and he died 16 months after diagnosis. CONCLUSIONS: This case highlights Purtscher's retinopathy and renal cortical necrosis might be considered as a recognized pair complication of acute pancreatitis.
