Abstract Background to evaluate whether the sildenafil citrate in women undergoing assisted reproduction ameliorate the clinical outcomes. Methods We performed a comprehensive literature search for published randomized controlled trials (RCT) in Medline, Embase, Scopus, Web of Science and Cochrane Central Register of Controlled Trials from inception to 25 Jun 2020. Literature screening, selection of relevant studies, assessment risk of bias and data extraction was conducted independently by two reviewers. We combined study data using the random-effects model. Results Sixteen trials including 1,589 women (771 cases and 818 controls) were included in meta-analysis. Pooling results from five trials, which compared clinical pregnancy between sildenafil citrate and placebo, showed a significantly higher probability of clinical pregnancy in sildenafil citrate group (RR: 1.57, 95% CI: 1.05, 2.36, I2 = 0%). The probability of clinical pregnancy was significantly higher in women who received the combination of sildenafil citrate and clomiphene citrate compared with clomiphene citrate alone (RR: 1.31, 95% CI: 1.12, 1.53, I2 = 0%). Following the intervention, clinical pregnancy significantly increased in women who received the combination of estradiol valerate and sildenafil citrate compared to estradiol valerate (RR: 1.59, 95% CI: 1.05, 2.43, I2 = 0%). Following the intervention, endometrial thickness (ET) increased in women who received sildenafil citrate compared to women who received placebo (SMD: 1.32, 95% CI: 0.30, 2.34, I2 = 92.41%). The mean of ET was significantly higher in women who received the combination of sildenafil citrate and clomiphene citrate compared to women who received clomiphene citrate (SMD: 0.92, 95% CI: 0.49, 1.36). Conclusion Our systematic review and meta-analysis showed that luteal supplementation of sildenafil citrate (oral or vaginal), alone or adjuvant therapy can be used for improving the EM and clinical pregnancy rate in women undergoing assisted reproduction. However, given the methodological limitations the current evidence does not support its use in clinical practice yet.

Acne has several effects on physical symptoms, but the main impacts are on the quality of life, which can be improved by treatment. There are several acne treatments but less evidence comparing their relative efficacy. Thus, we assessed the comparative efficacy of pharmacological and nonpharmacological interventions for acne. We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials from inception to April 2019, to include randomized controlled trials for acne that compared topical antibiotics (TA), benzoyl peroxide (BPO), topical retinoids (TR), oral antibiotics (OA), lasers, light devices including LED device (LED), photodynamic therapy (PDT), and intense pulsed light, chemical peels (CP), miscellaneous therapies or complementary and alternative medicine (MTCAM), or their combinations. We performed Bayesian network meta-analysis with random effects for all treatments compared with placebo and each other. Mean differences (MDs) of lesions count and risk ratios of adverse events with their 95% credible intervals (CrIs) were calculated, and all interventions were ranked by the Surface Under the Cumulative Ranking (SUCRA) values. Additional frequentist additive network meta-analysis was performed to detect the robustness of results and potential interaction effects. Sensitivity analyses were carried out with different priors, and metaregression was to adjust for nine potential effect modifiers. In the result, seventy-three randomized controlled trials (27,745 patients with mild to moderate acne), comparing 30 grouped intervention categories, were included with low to moderate risk of bias. For adverse effects, OA had more risk in combination treatment with others. For noninflammatory lesions reduction, seventeen interventions had significant differences comparing with placebo and three interventions (TR+BPO: MD = −21.89, 95%CrI [−28.97, −14.76]; TR+BPO+MTCAM: −22.48 [−34.13, −10.70]; TA+BPO+CP: −20.63 [−33.97, −7.13]) were superior to others with 94, 94, and 91% SUCRA values, respectively. For inflammatory lesions reduction, nineteen interventions were significantly better than placebo, and three interventions (TR+BPO: MD = −12.13, 95%CrI [−18.41, −5.80]; TR+BPO+MTCAM: −13.21 [−.39, −3.04]; LED: −11.30 [−18.34, −4.42]) were superior to others (SUCRA: 81, 81, and 77%, respectively). In summary of noninflammatory and inflammatory lesions results, TR+BPO and TA+BPO were the best options compared to others. The frequentist model showed similar results as above. In summary, current evidence supports the suggestion that TR+BPO and TA+BPO are the best options for mild to moderate acne. LED is another option for inflammatory lesions when drug resistance occurs. All the combinations involved with OA showed more risk of adverse events than others. However, the evidence of this study should be cautiously used due to the limitations.

Aim of the Study. This systematic review and meta-analysis aims to evaluate the current evidence from randomized controlled trials (RCTs) related to the effectiveness and safety of acupuncture treatment (AT), including electroacupuncture or thread-embedding therapy in combination with modern technology, for chronic pelvic pain (CPP) in women. Materials and Methods. We searched 12 electronic databases up to December 2017. All randomized controlled trials evaluating the effect of AT for CPP were considered. Results. Four RCTs with 474 participants were included. The methodological quality of included studies was generally low. The results of meta-analysis of two studies showed that AT combined with conventional treatment (CT) was associated with significantly reduced CPP, based on the total effectiveness rate (n=277, mean difference = 1.29, confidence interval = 1.13 to 1.47, P=0.0001, I2 = 0%). Conclusions. This review suggests the potential of AT combined with CT compared to CT alone for treating female CPP. However, there is insufficient evidence to conclude that AT can be recommended as a complementary and alternative (CAM) treatment for women with CPP. To draw a firm conclusion, future studies should require not only lager, more rigorously designed RCTs but also research on different AT types. Protocol Registration Number. This study is registered with PROSPERO 2018 (CRD42018088627).

Abstract Objectives Intermittent fasting (IF) is a popular trending diet, yet there is limited evidence-based support considering its clinical impact on cardiometabolic outcomes. In an effort to inform the European Association for the Study of Diabetes (EASD) clinical practice guidelines for nutrition therapy, we conducted a network meta-analysis of randomized controlled trials (RCTs) comparing IF strategies and continuous energy restriction (CER) on cardiometabolic outcomes using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. Methods MEDLINE, EMBASE, and Cochrane databases were searched through Nov 2020. We included RCTs assessing the effect of IF strategies (alternate-day fasting (ADF), whole-day periodic fasting (WDF), time-restricted feeding (TRF)), CER, and ad libitum diet. Outcomes included body weight, fasting glucose and LDL-cholesterol. Two independent researchers extracted data and assessed risk of bias. A network meta-analysis was performed and data were expressed as mean differences (MD) with 95% confidence intervals (CI). The certainty of the evidence was assessed using GRADE. Results We identified 19 RCTs (n = 590) including adults of varying health backgrounds. ADF and CER both showed a benefit for body weight reduction compared to ad libitum diet (18 trials, n = 520; MD −3.95 kg [95% CI −6.09, −1.81] and MD −2.85 kg [95% CI −4.99, −0.71], respectively). For fasting glucose (17 trials, n = 590), TRF showed a benefit compared to ad libitum diet (MD −0.39 mmol/L [95% CI −0.59, −0.20]), to CER (MD −0.25 mmol/L [95% CI, −0.45 to −0.06]) and to WDF (MD −0.20 mmol/L [95% CI, −0.45, −0.05]). Furthermore, ADF showed a benefit in reducing LDL-cholesterol (17 trials, n = 590) compared to ad libitum diet (MD −0.21 mmol/L [95% CI −0.40, −0.1]), and to CER (MD −0.15 mmol/L [95% CI −0.31, −0.01]). The certainty of the evidence ranged from high to moderate due to variable downgrades for imprecision. Conclusions Current evidence provides a good indication that IF strategies have similar benefits to CER for weight loss but may have additional benefits for fasting glucose and LDL-cholesterol. Long-term high quality RCTs are needed to clarify the effect of different IF strategies on cardiometabolic outcomes.

In this commentary, we summarize the current evidence from randomized controlled trials on enteral lactoferrin supplementation in preterm neonates. Our recently completed systematic review includes 12 randomized controlled trials performed all over the world. Our meta-analysis suggests clinical benefit in decreasing late-onset sepsis, late-onset fungal sepsis, length of stay in the hospital and urinary tract infections. There were no adverse effects. There was no statistically significant decrease in necrotizing enterocolitis, mortality or neurodevelopmental impairment in lactoferrin supplemented preterm infants. There was significant statistical heterogeneity in the effects of lactoferrin on late-onset sepsis between larger and smaller studies, which may reflect either small study biases, differences in the effectiveness, dose or duration of supplemental lactoferrin products, or differences in underlying population risk, or any or all of these.

Abstract Background: The current approach for treating anemia in multiple myeloma (MM) patients entails prescribing recombinant erythropoetin (EPO) only if chemotherapy fails initially to raise hemoglobin (Hb) levels. However, this practice is not based on synthesis of the totality of evidence obtained from data of all trials testing EPO exclusively in myeloma patients. Objective: To conduct a systematic review/ meta-analysis (SR/MA) regarding the use of EPO in MM patients. Methods: We conducted a SR of all randomized controlled trials (RCTs) that studied the effect of EPO exclusively in MM patients. We searched all major electronic databases (MEDLINE, LILACS, EMBASE and the Cochrane Controlled Trials Register) as well as performing hand searches of relevant meeting proceedings (ASH, ASCO, EHA), and ongoing NCI trials. We included RCTs that had at least 10 patients in each arm and had compared the use of EPO against a control group. We also identified trials that compared different doses of EPO. We excluded trials that enrolled patients treated with high-dose myeloablative chemotherapy followed by stem cell transplantation or hemodialysis. Results: We identified more than 500 relevant studies; 6 trials met our eligibility criteria and were included in the analysis. Five trials (4 published as full text manuscripts and 1 as the abstract) compared epoetin alpha against a control [placebo (2 trials) or no therapy with or without specification of red cells transfusion trigger level (3 trials)] in anemic MM patients. One trial compared 2 different schedules of epoetin alpha. No trial tested the effect of darbopoeitin. All 5 trials that studied EPO against controls used initial doses of 150 IU 3x/week SC with the possibility of increasing to 300 IU if necessary. In the majority of trials the patients had been receiving chemotherapy at the time EPO was administered. The number of patients included in each trial ranged from 24 to 145. All trials concluded that EPO was superior to a placebo or no treatment in terms of Hb increase. Two trials also concluded that EPO improves quality of life. Our meta-analysis showed that hematological response was favored in the group receiving EPO [relative risk (RR) 7.75; 95% CI 4.19 to 14.35, 4 trials, n = 272]. Mean Hb level improvement with EPO was also significant [weighted mean difference (WMD) 2.29; 95% CI2.00 to -2.58, 3 trials, n = 235]. In terms of adverse events, hypertension was more often found in the EPO arm [RR 5.80; 95% CI 1.30-25.90, 4 trials, n = 290]. Survival and data related to tumor response were not available in all trials. Critical appraisal indicated that available evidence was modest in quantity (5 trials, n= 385 total patients enrolled) and poorly reported in all important methodological domains. Conclusion: Available body of evidence suggests that EPO improves hematological outcomes in patients with myeloma. However, the quality of current evidence is insufficient, data on most important patients’ outcomes are lacking (e.g. survival etc.), thus preventing us from making definitive recommendations regarding the role of EPO in managing anemia in the myeloma setting. A definitive RCT to resolve the role of EPO in myeloma is indicated.

Background. Chinese oral herbal paste has been widely used in the treatment of chronic obstructive pulmonary disease (COPD). However, the treatment effects of herbal paste were controversial and lack evidence to support its clinical use. This study aims to systematically assess the efficacy and safety of Chinese oral herbal paste for the treatment of stable COPD. Methods. PubMed, Web of Science, CENTRAL, EMBASE, CNKI, VIP, CBM, and WANFANG database in addition to two websites of clinical trial registry were searched from respective inception to August 2019. Only randomized controlled trials (RCTs) studying Chinese herbal paste for the treatment of stable COPD were included. Methodological quality was assessed based on Cochrane risk of bias and GRADE approach. Data were analyzed using RevMan 5.3. Results. A total of 19 RCTs with 1303 individuals compared Chinese oral herbal paste and Western medicine (WM) with WM alone were included for meta-analysis. The review showed compared with WM alone, the combination of herbal paste and WM reduced exacerbation frequency. Subgroup analyses showed that after two to three months of treatment, compared with WM alone, Chinese herbal paste plus WM significantly decreased the St George’s Respiratory Questionnaire (SGRQ) scores, COPD assessment test (CAT) scores, and scores of traditional Chinese medicine (TCM) syndrome, and improved clinical effective rates, lung function, and 6-minute walk distance. No serious adverse events related to herbal paste were reported. Conclusion. Current evidence showed that Chinese oral herbal paste may be an effective and well-tolerated adjuvant therapy for stable COPD. Considering the risks of bias and heterogeneity, more high-quality, well-designed RCTs are still needed.

Background. Robotic surgery has been recently used as a novel tool for rectal surgery. This study assessed the current evidence regarding the efficiency, safety, and potential advantages of robotic rectal surgery (RRS) compared with laparoscopic rectal surgery (LRS). Methods. We comprehensively searched PubMed, Embase, and the Cochrane Library databases and performed a systematic review and cumulative meta-analysis of all randomized controlled trials (RCTs) assessing the 2 approaches. Results. Seven RCTs including a total of 1022 cases were identified. The conversion rate is significantly lower for RRS (odds ratio: 0.29; 95% confidence interval: 0.09 to 0.96; P = .04). The length of the distal margin was significantly shorter in the LRS group than in the RRS group (weighted mean difference: 0.60; 95% confidence interval: 0.09 to 1.10; P = .02). Perioperative complication rates, harvested lymph nodes, positive circumferential resection margins, complete total mesorectal excision, first flatus, and length of stay did not differ significantly between approaches ( P > .05). Conclusions. This meta-analysis indicates that RRS is a safe and effective approach. It is not inferior to LRS in terms of oncologic outcomes and postoperative complications. Future large-volume, well-designed RCTs with extensive follow-up are awaited to confirm and update the findings of this analysis.

Background. The effect of phytoestrogen on postmenopausal quality of life is unclear. This study evaluated the effects of phytoestrogen supplement on quality of life for postmenopausal women. Methods. We conducted a systematic review and meta-analysis of randomized controlled trials on the effects of phytoestrogen supplements on the quality of life of postmenopausal women. We searched PubMed, MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials on March 31, 2018, for relevant randomized controlled trials. Two authors independently selected studies, assessed risk of bias, and extracted data. Disagreement was resolved through discussion with a third author. Results. We involved 10 articles in the systematic review. 8 studies and a total of 1,129 subjects were included in the meta-analysis. The questionnaires used in the evaluation of quality of life were as follows: SF-36, 4 studies; MENQOL, 4 studies; For Short Form 36 surveys, phytoestrogen groups scored significantly higher for body pain (mean difference = 3.85, 95% confidence interval [CI] = [1.14, 6.57], P < 0.01), mental health (mean difference = 4.01, 95% CI = [1.49, 6.57], P < 0.01), and role limitations caused by emotional problems domains (mean difference = 3.83, 95% CI = [1.81, 5.85], P < 0.01). No statistically significant difference was obtained from Menopause-Specific Quality of Life surveys (vasomotor domain mean difference 0.14, 95% CI = [−0.08, 0.36], P = 0.20; physical domain mean difference 0.20, 95% CI [−0.08, 0.48], P = 0.15; psychological domain mean difference −0.10, 95% CI [−0.26, 0.07], P = 0.27; sexual domain mean difference −0.17, 95% CI [−0.42, 0.09], P = 0.19). Conclusion. Current evidence does not support phytoestrogen supplementation improving postmenopausal quality of life. Further comprehensive trials or long-term follow-up studies are warranted.
