Effect of instrumental music on anxiety and depression among hemodialysis patients: A randomized controlled trial

BACKGROUND

Hemodialysis patients suffer from mental disorders such as anxiety and depression. One of the known nonpharmacological methods to eliminate these disorders is music therapy. The present study aimed to investigate the effect of instrumental music on state depression and anxiety in hemodialysis patients.

MATERIALS AND METHODS

This study was a clinical trial. The population was hemodialysis patients in Hamedan in 2017 and 50 patients were selected and randomly divided into experimental and control groups. The duration each time of the instrumental music intervention for the experimental group was 3 weeks, 3 times a week for 20 min. Data were measured by beck depression inventory and SpeilBerger State-Trait Anxiety Inventory-Y1 before the intervention and immediately after the last intervention and analyzed using Yates correction, Chi-square test, Mann-Whitney U-test, independent t-test, and Wilcoxon test.

RESULTS

No significant difference between the intervention and control groups was observed before the study in terms of demographic variables (P > 0.05). In the intervention group, the mean and standard deviation of the depression score before the intervention was 8.99 ± 23.68 and after the intervention reached 7.54 ± 14.88, which shows that the variable was significant (P = 0.001); however, no significant difference was observed in the control group. In the intervention group, the mean of state anxiety before the intervention was 10.05 ± 53.76 and after the intervention reached 9.76 ± 42.48, which was statistically significant (P = 0.004), while no significant difference was observed in the control group.

CONCLUSION

The results indicate the positive effect of instrumental music on reducing anxiety and depression in hemodialysis patients. It is recommended that this therapy be used as a nursing method to reduce state anxiety and depression in hemodialysis patients.

Risk of chronic kidney disease in women with a history of preterm delivery: Tehran Lipid and Glucose Study

BACKGROUND

Preterm delivery (PTD) may predict the risk of long-term maternal complications. Little is known about the association between preterm delivery and maternal risk of chronic kidney disease (CKD).This study aimed to explore whether a history of preterm delivery is associated with the risk of maternal CKD.

METHODS

In this population-based cohort study within the framework of the Tehran Lipid and Glucose Study (TLGS), a total of 3035 women with at least one delivery met our eligibility criteria. A time-dependent Cox proportional-hazards regression model was used to measure the hazard ratios (HRs) and 95% confidence intervals (CIs) for evaluating the association between history of preterm delivery and risk of CKD, adjusted for smoking, parity, age at first delivery, body mass index, educational level, preeclampsia, and gestational diabetes mellitus.

RESULTS

A total of 212 women with a history of at least one preterm delivery and 2823 women with term delivery were included. The median (interquartile range) follow-up in the preterm and term delivery groups was 16 (13.0-17.0) and 16 (14.0-17.0) years, respectively. The results of multivariate Cox regression model, adjusted for confounders, showed that the risk of CKD significantly increased by 46% in women with a history of preterm delivery. Moreover, according to the time-dependent Cox regression analysis, the risk of CKD in women with a history of preterm delivery was 2.68 (95% CI 1.02, 7.05, P = 0.04) fold higher than among those with no history of  preterm delivery.

CONCLUSION

Pregnancy if complicated by preterm delivery, may increase the risk of future maternal morbidities. Our findings suggest that a history of preterm delivery was associated with an increased maternal risk of CKD in the long term. Further longitudinal studies are needed to confirm our findings.

Renal impairment in Alport syndrome pregnant woman: Case report and review of the literature

Pregnant women affected by Alport syndrome often struggle with worsening of renal function during pregnancy. We focused the attention on the optimal management of the kidney disease in these women in order to avoid maternal-fetal complications.
