Impact of Fish Intake Frequency on Cardiovascular Disease-Specific Survival in Hemodialysis Patients.

Introduction: Cardiovascular disease (CVD) is the leading cause of death in hemodialysis patients (HPs). As a food source, fish contains both CVD-preventive and CVD-promoting fatty acids; however, there is no consensus on fish consumption as a preventive measure for CVD in HPs. This single-center longitudinal cohort study aims to assess the impact of fish intake frequency (FIF) per week on CVD in Japanese HPs. Methods: Upon the initiation of the study, 148 HPs were evaluated to determine the FIF, and blood samples were analyzed. These patients were then monitored for 6 years.The relationships between each FIF and blood sampling data, CVD-specific survival (CSS), and new CVD-free survival (nCFS) were statistically calculated using Kaplan-Meier survival curves. Results: During the observation period, 65 deaths were reported, 16 of which were attributed to CVD. Further, 53 patients developed new CVD onset, and no association was found between the FIF and blood sampling data. Based on the Kaplan-Meier survival curves, there was a significant difference in the CSS probability rates at 72 months between patients with an FIF of ≥4 (0.719, 95% confidence interval (CI): 0.530-0.842) and those with an FIF of ≤3 (0.930, 95% CI: 0.851-0.968) (p < 0.01). However, the nCFS probability at 72 months did not significantly differ between patients with an FIF of ≥4 and those with an FIF of ≤3. Multivariate Cox proportional hazards regression showed that an FIF of ≥4 (hazard ratio: 3.64, 95% CI: 1.22-10.9, p = 0.02) was an independent predictor of CSS, but not of nCFS. Conclusions: It was suggested that a higher FIF in HPs might be one of the risks for developing CVD with increased mortality.

A case of adrenal myelolipoma complicated with Prader-Willi syndrome.

Introduction: Prader-Willi syndrome is a congenital disorder that occurs in one in 10 000-30 000 children and is characterized by obesity, short stature, and intellectual disability. Case presentation: A 24-year-old male patient with Prader-Willi syndrome presented with an enlarged adrenal tumor. Computed tomography detected a well-defined mass. Magnetic resonance imaging revealed an increased signal intensity predominantly in fatty areas, suggesting adrenal myelolipoma. Laparoscopic left adrenalectomy was performed. Postoperatively, the patient developed mild pulmonary atelectasis, myelolipoma was confirmed by histopathology, and there was no recurrence at approximately 2 years postoperatively. Conclusion: This is the first report of Prader-Willi syndrome complicated with adrenal myelolipoma, which was removed laparoscopically.
