Evaluating the understandability and actionability of online educational videos on pre-dialysis chronic kidney disease.

AIM: It remains undetermined whether online education videos for Japanese patients with chronic kidney disease (CKD) are easy to understand and allow adoption of behavioural changes. This study quantitatively assessed the understandability and applicability of online education videos for patients with CKD. METHODS: In September 2021, we identified 200 videos on YouTube using the Japanese translations of the keywords 'kidney,' 'kidney disease,' 'CKD,' and 'chronic kidney disease.' We used the Japanese version of the Patient Education Materials Assessment Tool to evaluate the understandability and usability of webpages on a scale of 0% to 100%. The cut-off was set at 70%. RESULTS: A total of 54 videos were evaluated. The overall understandability and actionability of the materials were 57.6 (SD = 22.6) and 53.7 (SD = 33.4), respectively. Approximately 70% and 60% of the materials were considered insufficiently understandable and actionable, respectively. Most videos lacked a summary and had difficulty in using only everyday language. Most videos included at least one action for the audience to take. However, many failed to break down the action into sequential steps. They also lack visual aids to encourage the audience to take action. CONCLUSION: Our results suggest that current information on pre-dialysis chronic kidney disease was not presented in a manner that can be applied by laypeople.

Paralytic Ileus during Treatment of Pulmonary and Renal Tuberculosis in a Non-Human Immunodeficiency Virus Patient: An Unusual Presentation of Tuberculosis-immune Reconstitution Inflammatory Syndrome.

Paralytic ileus as tuberculosis-immune reconstitution inflammatory syndrome (TB-IRIS) is extremely rare. We herein report a 44-year-old man with pulmonary and renal tuberculosis who developed paralytic ileus 14 days after starting antituberculosis therapy (ATT) despite an initial favorable response to ATT. Paralytic ileus was successfully managed with conservative care. He initially required hemodialysis because of obstructive uropathy due to renal tuberculosis, but he was able to withdraw from dialysis after placement of ureteral stents. TB-IRIS can affect organs other than the original sites of tuberculosis, and the combined use of steroids may be effective for its prevention and treatment.

A case of proliferative glomerulonephritis with monoclonal IgG deposits (PGNMID) that responded favorably to steroid therapy.

Proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID) generally has a poor prognosis and the consensus is that it needs to be treated with clone-directed therapy. However, the prognosis of PGNMID is heterogenous and some cases have been successfully treated using other therapeutic strategies. We herein report a case of PGNMID that responded favorably to steroids without clone-directed therapy. An 18-year-old woman was referred to a nephrologist with proteinuria detected in an annual health check-up. Over a 3-year period, the concentration of creatinine (Cr) increased from 0.76 to 1.00 mg/dL and proteinuria from 0.35 to 1.9 g/g Cr. Monoclonal gammopathies were not detected in her serum or urine. Based on the findings of kidney biopsy at the age of 21 years, the patient was diagnosed with proliferative glomerulonephritis with monoclonal IgG1-kappa deposits. The histological feature was mesangial proliferative glomerulonephritis with advanced glomerulosclerosis, which is a rare presentation of PGNMID. Intravenous methylprednisolone pulse therapy was initiated, followed by oral prednisolone at a dose of 30 mg daily. One year later, a second kidney biopsy revealed a significant decrease in mesangial deposits of IgG1-kappa. Prednisolone was gradually tapered and discontinued 2 years after the first kidney biopsy. At the time of prednisolone withdrawal, urinalysis showed proteinuria of 0.2 g/g Cr without hematuria. Kidney function remained stable throughout the treatment period.

Incidence and risk factors of contrast-induced nephropathy after transcatheter arterial chemoembolization in hepatocellular carcinoma.

BACKGROUND: Transcatheter arterial chemoembolization (TACE) is widely used for unresectable hepatocellular carcinoma (HCC). The purpose of this study was to investigate incidence and risk factors of contrast-induced nephropathy (CIN) after TACE in patients with HCC. METHODS: In this single-center retrospective study, we examined 461 consecutive TACE sessions in 260 patients between January 2003 and October 2015. CIN was defined as an increase in serum creatinine levels by ≥ 0.5 mg/dl or ≥ 25% from baseline within 72 h after TACE. We calculated incidence rate of CIN and tried to identify its risk factors by logistic regression analysis. RESULTS: Twenty-one cases of CIN (5%) were observed in 461 TACE sessions. One patient required subsequent hemodialysis transiently. In univariate analysis, tumor size > 5 cm [odds ratio (OR) 5.76, 95% confidence interval (CI) 2.34-14.14, p < 0.001], chronic kidney disease (OR 2.54, 95% CI 1.05-6.14, p = 0.04), serum hemoglobin level [OR 0.79 (per 1 g/dl increase), 95% CI 0.64-0.98, p = 0.03] and serum albumin level [OR 0.44 (per 1 g/dl increase), 95% CI 0.19-1.02, p = 0.05] were associated with the development of CIN. Stepwise logistic regression methods showed that tumor size > 5 cm (OR 7.81, 95% CI 2.99-20.46, p < 0.001) and serum albumin [OR 0.29 (per 1 g/dl increase), 95% CI 0.11-0.75, p = 0.01] were risk factors of CIN. CONCLUSIONS: In this study, HCC tumor size and lower serum albumin level were independent predictors of CIN after TACE.
