Association of daytime napping with incidence of chronic kidney disease and end-stage kidney disease: A prospective observational study.

BACKGROUND AND AIMS: Few studies have examined the relationship between daytime napping and risk of kidney diseases. We aimed to investigate the association of daytime napping with the incidence of chronic kidney disease (CKD) and end-stage kidney disease (ESKD). We also examined whether sleep duration modified the association of nap with CKD or ESKD. METHODS: We recruited 460,571 European middle- to older-aged adults without prior CKD or ESKD between March 13, 2006, and October 1, 2010, in the UK Biobank. Sleep behavior data were obtained through questionnaires administered during recruitment. The analysis of the relationship between napping and the occurrence of CKD and ESKD utilized Cox proportional hazards regression models. The modification role of sleep duration on the effect of nap on CKD and ESKD was also examined. RESULTS: After a mean follow-up of 11.1 (standard deviation 2.2) years, we observed 28,330 incident CKD cases and 927 ESKD cases. The daytime napping was associated with incident CKD (P for trend = .004). After fully adjusted, when compared with participants who did not take nap, those in sometimes and usually nap groups had higher risk of CKD. Nevertheless, the available evidence did not support a link between daytime napping and ESKD (P for trend = .06). Simultaneously, there was insufficient evidence suggesting that sleeping duration modified the association of daytime napping with incident CKD or ESKD. CONCLUSION: Daytime napping was associated with an increased risk of CKD. However, the absence of conclusive evidence did not indicate a connection between daytime napping and ESKD.

Triple therapy versus amphotericin B plus flucytosine for the treatment of non-HIV- and non-transplant-associated cryptococcal meningitis: retrospective cohort study.

Objectives Amphotericin B plus flucytosine is the most widely used induction therapy regimen for non-HIV-infected and non-transplant patients; however, the therapeutic outcomes are unsatisfactory, especially when two antifungal drugs are at sub-therapeutic doses. Methods In this study of induction therapy, all non-HIV-infected, non-transplant patients with a first episode of cryptococcal meningitis were divided into two groups. In group I, the patients received amphotericin B plus 5-flucytosine. In group II, in addition to amphotericin B and 5-flucytosine, the patients also received fluconazole. Results In this study, 32 patients were included in group I, and the other 30 were in group II. Although patients from group II had higher fungal burdens with approximately 2100 Cryptococci/ml CSF before treatment, they had a significantly higher frequency of satisfactory outcomes (80% vs. 50%, respectively, P = 0.014). Less time for more patients in group II to have CSF sterilization (P = 0.021; P = 0.046). And more patients in group II had improved neurological function circumstances evaluated by comparing the BMRC staging between patients at discharge and follow-up 10 weeks (P = 0.032). No significant difference was observed in the incidence of adverse events between the two groups. Conclusion Triple therapy a superior alternative induction regimen for patients with non-HIV- and non-transplant-associated cryptococcal meningitis.
