A protocol of systematic review and meta-analysis of neuromuscular electrical stimulation for interstitial cystitis.

BACKGROUND: This study will examine the effectiveness and safety of neuromuscular electrical stimulation (NMES) for the treatment of patients with interstitial cystitis (IC). METHODS: We will retrieve the following electronic databases from their commencements to the March 1, 2020 to discover all related potential studies: MEDLINE, EMBASE, Cochrane Library, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Chinese Scientific Journal Database, and WANFANG Database. Randomized controlled trials related to the NMES for the treatment of patients with IC will be included, regardless publication status and language. Literature selection, data collection, and study quality assessment will be independently performed by 2 authors. The extracted data will be expressed as risk ratio and 95% confidence intervals for dichotomous data, and mean difference or standard mean difference and 95% confidence intervals for continuous data. RevMan V.5.3 software will be employed for statistical analysis. RESULTS: This study will summarize current high quality randomized controlled trials to appraise the effectiveness and safety of NMES for the treatment of patients with IC. CONCLUSION: The findings of this study will provide helpful evidence to determine whether NMES is an effective treatment for patients with IC or not.

Efficacy of pirarubicin for nonmuscle invasive bladder cancer: A protocol of systematic review and meta-analysis.

BACKGROUND: This study will aim to appraise the efficacy and safety of pirarubicin for the treatment of patients with nonmuscle invasive bladder cancer (NMIBC). METHODS: We will perform a comprehensive literature search in MEDLINE, EMBASE, Cochrane Library, Scopus, PsycINFO, Web of Science, Allied and Complementary Medicine Database, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure from their beginning to the February 29, 2020. All randomized controlled trials of pirarubicin for NMIBC will be included regardless limitations related to the language and publication time. Two researchers will independently select studies from searched records, extract data from included randomized controlled trials, and assess study quality using Cochrane risk of bias tool. Any differences between them will be solved with the help of another researcher. RevMan 5.3 software will be utilized for statistical analysis. RESULTS: This study will provide a synthesis of current evidence to investigate the efficacy and safety of pirarubicin for NMIBC using overall survival, progression-free survival, recurrence-free survival, quality of, rates of recurrence, and adverse events. CONCLUSION: This study will explore whether or not pirarubicin can be used as an effective and safety treatment for patients with NMIBC. REGISTRATION NUMBER: INPLASY202040113.

Can docetaxel combined prednisone effectively treat hormone refractory prostate cancer?: A protocol of systematic review and meta-analysis.

BACKGROUND: Previous studies have reported that docetaxel combined prednisone (DP) has been used for the treatment of patients with hormone refractory prostate cancer (HRPC). However, its results are still inconsistent. Therefore, this study will synthesize the latest evidence of the efficacy and safety of DP for the treatment of patients with HRPC. METHODS: Cochrane Library, PUBMED, EMBASE, Web of Science, CINAHL, CBM, and CNKI will be searched to identify randomized controlled trials published from their inception to the March 1, 2020, irrespective language and publication time restrictions. We will calculate the pooled effects of dichotomous outcomes as risk ratio and 95% confidence intervals, and that of continuous outcomes as standardized mean difference or mean difference and 95% confidence intervals. Study quality will be assessed using Cochrane risk of bias, and quality of evidence for main outcome will be evaluated using Grading of Recommendations Assessment Development and Evaluation. Statistical analysis will be performed using RevMan 5.3 software. RESULTS: This study will appraise the efficacy and safety of DP for the treatment of patients with HRPC. The primary outcome includes overall survival, and the secondary outcomes comprise of progression-free survival, prostate-specific antigen response rate, duration of prostate-specific antigen response, objective tumor response rate, disease-free survival, quality of life, and adverse events. CONCLUSION: The results of this study may provide helpful evidence of DP for the treatment of patients with HRPC.Systematic review registration: INPLASY202040112.
