Depression and quality of life in relation to decreased glomerular filtration rate among adults with hypertension in rural northeast China

The mediating effect of sleep quality and fatigue between depression and renal function in nondialysis chronic kidney disease: a cross-sectional study

BACKGROUND

Depressive symptoms, fatigue, and poor sleep quality are associated with renal function deterioration in patients with nondialysis chronic kidney disease (CKD-ND). This study was designed to examine whether fatigue and sleep quality are mediators of the association between depression and renal function.

METHODS

This study adopted a cross-sectional study design. Patients with CKD-ND aged 20 years or older were recruited by purposive sampling at a medical center in Central Taiwan from December 2020 to July 2021. Data were collected using the Emotional and Social Support Scale, Fatigue Scale, Beck Depression Inventory-II (BDI-II), and Pittsburgh Sleep Quality Index. Medical records were reviewed to obtain the estimated glomerular filtration rate (eGFR) for the next month. The relationships among variables were analyzed using structural equation modeling to assess the goodness-of-fit of the model. Then, the bootstrapping method was used to analyze the mediated effect.

RESULTS

Two hundred forty-two participants (mean age 70.5 years and 53% males) were included in the analysis. About 39% of the participants met the criteria for depressive symptoms in BDI-II, and 91% reported having sleep disturbances. Participants' degree of fatigue was not high (20.4 ± 13.3). The average eGFR was 25.45 mL/min/1.73 m ² (± 13.36). The results showed that fatigue, sleep quality, and eGFR were significantly correlated with depression. The total effect size was - 0.8304 (95% confidence interval [CI], - 0.9602 to - 0.7006), and the indirect effect size was - 0.1738 (95% CI, - 0.2812 to - 0.0651), which was a statistically significant difference, indicating that the model has a mediating effect. According to mediation analysis, fatigue and sleep quality had a significant indirect effect on the relationship between depression and renal function (95% CI, - 0.0587 to - 0.0039).

CONCLUSIONS

The findings suggest that fatigue and poor sleep quality may mediate the association between depression and renal function.

Effect of novel oral anticoagulants on Hospital Anxiety and Depression Scale scores

BACKGROUND

The negative impact of atrial fibrillation (AF) on health-related quality of life has been extensively documented. The aim of this study was to compare the Hospital Anxiety and Depression Scale (HADS) scores of patients with non-valvular AF during warfarin administration and after switching to novel oral anticoagulants (NOACs).

METHODS

The study comprised 100 consecutive patients on warfarin treatment between July 2018 and January 2019 for whom a transition to NOACs was planned. All patients completed the HADS at the start of the study and at least 3 months after that date.

RESULTS

The mean value of HADS-A (5.9 ± 2.1 vs. 4.4 ± 1.6, p < 0.001) and HADS-D (4.4 ± 1.7 vs. 3.7 ± 1.4, p < 0.001) scores was significantly higher in patients when they used warfarin than when they switched to NOACs. Analysis revealed that there was a significant correlation between HADS-A and HADS-D scores with age and history of bleeding (p < 0.001). The highest scores were found for patients with a history of bleeding and age ≥75 years (p < 0.001).

CONCLUSION

Our study demonstrates that patients with nonvalvular AF under treatment with NOACs had lower HADS-A and HADS-D scores compared with patients on warfarin treatment. These findings suggest that NOACs may increase the quality of life and decrease morbidity and mortality by reducing anxiety and depression.

Comparison of Quality of Life in Patients Undergoing Hemodialysis and Peritoneal Dialysis: a Systematic Review and Meta-Analysis

BACKGROUND/AIMS

The increase in the survival rate of patients with chronic renal failure due to substitution treatment prompts an investigation of their quality of life (QoL), a key measure to evaluate the outcomes of chronic disease treatment. To determine whether hemodialysis or peritoneal dialysis provide a better QoL, a systematic meta-analysis was performed.

METHODS

We searched through the database Cinahl, Medline, PubMed, Scopus and Proquest, including articles published from 2011 until June 2016. We selected articles that compared, through KDQOL-SF 1.3 or 36 questionnaires, QoL among patients undergoing hemodialysis and peritoneal dialysis. The data was collected using Excel Office, and t-test has been performed on independent samples to identify significant differences.

RESULTS

Only some of the seven articles found significant differences between the two treatments. One of the studies showed a better QoL for peritoneal dialysis patients, while, on the contrary, two other studies support that the best QoL is in patients receiving hemodialysis. Another article displayed significant difference only for satisfaction in relation to care, better in patients on peritoneal dialysis, and for physical health, better in hemodialysis.

CONCLUSIONS

The analysis has not led to a unanimous conclusion. Quantitative analysis showed that the only statistically significant difference between the QoL of patients on hemodialysis and peritoneal dialysis regards the effect of kidney disease, which happens to be better in patients undergoing peritoneal dialysis.
