Comparison of desmopressin, alarm, desmopressin plus alarm, and desmopressin plus anticholinergic agents in the management of paediatric monosymptomatic nocturnal enuresis: a network meta-analysis.

OBJECTIVE: To assess the efficacy of desmopressin, alarm, desmopressin plus alarm, and desmopressin plus anticholinergic agent (AA) therapy in the management of paediatric monosymptomatic nocturnal enuresis (MNE) using a network meta-analysis. MATERIALS AND METHODS: We searched the electronic databases PubMed, Cochrane Library, EMBASE and Web of Science from inception to 1 March 2018. Randomized controlled trials (RCTs) that compared desmopressin, alarm, desmopressin plus alarm, and desmopressin plus AAs were identified. The network meta-analysis was conducted with software R 3.3.2 and STATA 14.0. RESULTS: Eighteen RCTs with a total of 1 649 participants were included. The meta-analysis results showed that complete response (CR) and success rates with desmopressin plus AAs were higher than with desmopressin or alarm monotherapy. Success rates for desmopressin plus alarm therapy were higher than for alarm monotherapy. No obvious difference was observed between desmopressin plus AAs and desmopressin plus alarm therapy with regard to CR rate and success rate. The relapse rate with alarm monotherapy was much lower than with desmopressin monotherapy. Adverse events seemed to be infrequently and tolerable for all treatments. The ranking probability results were as follows: desmopressin plus AA ranked first for the outcomes of CR and success, desmopressin plus alarm therapy ranked first for mean number of wet nights per week, and alarm therapy had the lowest relapse rate. CONCLUSIONS: The network meta-analysis showed that desmopressin had similar efficacy to alarm therapy but a higher relapse rate. Desmopressin plus AA therapy was associated with better efficacy than and a similar relapse rate to desmopressin monotherapy. Desmopressin plus alarm therapy was similar to both desmopressin and alarm monotherapy in efficacy. All treatments, including desmopressin plus AAwere associated with tolerable adverse events; however, additional high-quality studies are needed for further evaluation of these treatments.

Prognosis and risk factors of patients with upper urinary tract urothelial carcinoma and postoperative recurrence of bladder cancer in central China.

BACKGROUND: To investigate the prognostic risk factors and postoperative recurrence of bladder cancer in patients with upper urinary tract urothelial carcinomas (UTUCs). METHODS: Data of 439 UTUC patients were retrospectively analyzed. Follow-up and analysis of smoking effects, consumption of traditional Chinese medicine containing aristolochic acid, history of bladder cancer, age, sex, presence or absence of diabetes mellitus (DM), metformin use, tumor characteristics (number, location, stage, grade), and open or laparoscopic surgery on the prognosis of UTUCs were performed. Cox proportional hazard regression analysis was performed to analyze the relationship between various factors and the postoperative survival rate. The survival rate was analyzed using the Kaplan-Meier method. Moreover, logistic regression analysis was performed to analyze the relationship between the above mentioned factors and postoperative recurrence of bladder cancer. RESULTS: Overall, 439 patients met, including 236 males (53.7%) and 203 females (46.3%), the criteria for the final statistical analysis, and the average age was 66.7 years. The 1-, 3-, and 5-year overall survival rates of 439 UTUC patients were 90.0, 76.4, and 67.7%, respectively. The 5-year survival rates of T1, T2, T3, and T4 patients were 90.2%, 78%, 43.8%, and 18.5%, respectively. Factors influencing the long-term survival rate of UTUC patients were smoking, taking traditional Chinese medicine containing aristolochic acid, history of bladder cancer, age, tumor size, tumor stage, tumor grade, and lymph node metastasis. The risk factors related to postoperative bladder cancer recurrence were advanced tumor stage, high grade tumor, preoperative ureteroscopy, ureteral urothelial carcinoma, no postoperative bladder perfusion chemotherapy and DM without metformin use. CONCLUSIONS: Advanced tumor stage and presence of a high-grade tumor were risk factors for not only poor UTUC prognosis but also BC recurrence. In addition, preoperative ureteroscopy, ureteral urothelial carcinoma and DM without metformin use were high risk factors for BC recurrence, whereas regular postoperative bladder perfusion chemotherapy was a protective factor.

Study on neuropathological mechanisms of primary monosymptomatic nocturnal enuresis in children using cerebral resting-state functional magnetic resonance imaging.

Primary monosymptomatic nocturnal enuresis (PMNE) is a heterogeneous disorder, which remains a difficult condition to manage due to lack of knowledge on the underlying pathophysiological mechanisms. Here we investigated the underlying neuropathological mechanisms of PMNE with functional MRI (fMRI), combining the amplitude of low frequency fluctuation (ALFF), regional homogeneity (ReHo), and seed-based functional connectivity (seed-based FC) analyses. Compared to the control group, PMNE group showed decreased ALFF value in the left medial orbital superior frontal gyrus (Frontal_Med_Orb_L), and increased ReHo value in the left superior occipital gyrus (Occipital_Sup_L). With left thalamus as the seed, PMNE group showed significantly decreased functional connectivity to the left medial superior frontal gyrus (Frontal_Sup_Medial_L). We conclude that these abnormal brain activities are probably important neuropathological mechanisms of PMNE in children. Furthermore, this study facilitated the understanding of underlying pathogenesis of PMNE and may provide an objective basis for the effective treatment.
