A Meta-analysis of Outcomes After Routine Aspiration of the Gallbladder During Cholecystectomy

Abstract We conducted a meta-analysis of published literature comparing outcomes after aspirating (ASP) the gallbladder versus nonaspiration (NASP). Electronic databases were searched from January 1985 to November 2009. A meta-analysis was performed to obtain a summative outcome. Two randomized, controlled trials involving 360 patients were analyzed. A total of 180 patients were in the ASP group, and 180 were in the NASP group. There was no significant increase in operative time in the ASP group compared with the NASP group [random-effects model: standardized mean difference, −0.72; 95% confidence interval (CI), −2.16, 0.71; z = 0.99; df = 1; P = 0.32], but there was significant heterogeneity among trials (Q = 42.4; P < 0.001; I2 = 98%). Patients undergoing ASP were less likely to have a gallbladder perforation [random-effects model: risk ratio (RR), 0.42; 95% CI, 0.19, 0.96; z = 2.05; df = 1; P < 0.05], but no difference was found regarding the loss of gallstones (random-effects model: RR, 1.33; 95% CI, 0.30, 5.85; z = 0.38; df = 1; P = 0.70). No difference was seen for liver bed bleeding (P = 0.43) or overall 30-day infection rates (P = 0.66). After aspiration, gallbladder perforation rates may be lower. This does not appear to translate into decreased loss of gallstones or infection rates. There was no significant difference between techniques in blood loss from the liver bed. Further randomized, controlled trials and follow-up studies are required to confirm these results and to establish long-term sequelae.

ObjectiveOur aim was to conduct a systematic review and meta-analysis to assess the effectiveness and safety of tea supplements for patients with polycystic ovary syndrome (PCOS).MethodsWe conducted searches of the published literature in PubMed, EMBASE, Cochrane Library, Web of Science, Chinese Biomedical Literature Database, Chinese National Knowledge Infrastructure (CNKI), VIP database, and Wanfang Database in 1985 to September 2021. Data from randomized controlled trials (RCTs) were obtained to assess the effects of tea versus placebo in women with PCOS. Weighted mean differences (WMDs) were pooled using a random-effects model or risks ratios (RRs) using a random-effects model.ResultsSix RCTs (235 participants) were included in our systematic review. Tea supplements as adjuvant therapy led to greater improvement in body weight (WMD −2.71, 95% CI −4.95 to −0.46, P = 0.02, I2 = 0%), fasting blood glucose (FBG: WMD −0.40, 95% CI −0.59 to −0.20, P < 0.0001, I2 = 0%) and fasting insulin (FINS: WMD −3.40, 95% CI −4.76 to −2.03, P < 0.00001, I2 = 0%) when compared with placebo. There were no significant differences of body mass index, waist circumference, hip circumference, waist-to-hip ratio (WHR), body fat rate, total testosterone, free testosterone (FT), dehydroepiandrosterone, luteinizing hormone or follicular-stimulating hormone (FSH) between the two groups. In addition, subgroup analysis suggested that green tea was effective on body weight, FINS, FBG, FT, and FSH, and herbal tea can also reduce FT levels, tea supplements had a significant impact on FBG and FSH in trials with intervention duration ≥ 3 months, and intervention lasting less than 3 months can improve FINS. Tea had significant effect on reducing WHR, FBG and FSH in Asian PCOS patients, but not in Caucasians. And there was no statistically significant effect of tea on weight and FINS in Asians, but it was effective for Caucasian participants. Compared with placebo, tea supplements did not cause significant adverse reactions (RR 1.45, 95% CI 0.30 to 6.90, P = 0.65, I2 = 0%).ConclusionThis meta-analysis suggests that consumption of tea supplementation in women with PCOS could significantly decrease the levels of FBG and FINS as well as reduce body weight. Especially green tea, not only has the above effects, but also has a significant effect on improving a variety of reproductive hormone indexes. Furthermore, tea supplementation is a relatively safe therapy for PCOS patients.

Abstract Background A systematic review and meta-analysis was conducted to compare the safety and efficiency of nephroscopy and cystoscopy in transurethral cystolithotripsy (TUCL) for bladder stones (BS). Methods The PubMed, Web of Science, Embase, EBSCO, and Cochrane Library databases were searched up to January 2021 for studies assessing the effect of different types of endoscopes among patients who underwent TUCL. The search strategy and study selection process were in accordance with the PRISMA statement. Results Five randomized controlled trials were included in the meta-analysis. The results showed no difference in stone-free rate (RR = 1.00, CI = 0.98–1.02, p = 1.00) between the two groups and nonsignificant heterogeneity (I2 = 0%, p = 1.00), and all patients were rendered stone free. Use of the nephroscope significantly shortened the operative time compared with the cystoscope group (RR= − 26.26, CI = − 35.84 to − 16.68, p < 0.00001), and there was significant heterogeneity (I2= 87%, p < 0.00001). There was no significant difference in mean urethral entries (RR = 0.66, CI = − 0.71 to − 2.04, p = 0.35), hospitalization (MD = 0.08, 95% CI = − 0.07 to 0.23, p = 0.31) or total complication rate (RR=1.37, 95% CI = 0.47–4.00, p = 0.56) between the two groups. Conclusions In conclusion, this systematic review demonstrates that both nephroscopy and cystoscopy have high stone clearance efficiency, low rates of complications and short hospitalizations. The mean urethral entries depend on the treatment method for large stone fragments. However, the use of nephroscopy can significantly reduce the operative time.

Objectives. This study aimed to evaluate the safety and efficacy of acupuncture in the treatment of urinary retention (UR). Methods. Randomized controlled trials investigating the effectiveness of acupuncture in the treatment of UR were identified by searching seven comprehensive databases (Cochrane Library, PubMed, Embase, China National Knowledge Infrastructure, Wanfang Database, China Science and Technology Journal Database, and Chinese Biomedical Literature Database) prior to September 2020. Data analysis was performed using RevMan, version 5.3, and Stata software, version 14.0. Results. A total of 12 studies with 979 participants were included. A random-effects model was used to conduct a meta-analysis on the acupuncture group and the control group. The results show that acupuncture can effectively promote spontaneous urination and reduce anxiety in patients with poor urination (relative risk: 1.35; 95% confidence interval (CI): 1.19–1.53; P < 0.00001 ). The random-effects model showed significant differences in residual urine volume between the acupuncture group and the control group (MD: −84.79, 95% CI: −135.62 to −33.94; P = 0.001 ). Conclusion. Acupuncture is safe and effective in the treatment of UR. However, since the current level of evidence is limited, high-quality, large-sample, multi-center, clinical randomized controlled trials are needed to further confirm our conclusions in the future.

Background: The prevalence of Familial Hypercholesterolemia (FH) is estimated to be 1 in 250 US adults. The advent of PCSK9 inhibitors has led a to a paradigm shift in the management of these patients. The purpose of this study was to analyze the efficacy of PCSK9 inhibitors in patients with heterozygous or homozygous FH. Methods: Pubmed, EMBASE and clinicaltrials.gov were searched for randomized controlled trials of PCSK9 inhibitors. Trials that exclusively recruited FH patients or those that reported data separately for FH patients were included. The primary outcome of this analysis was mean difference in LDL-C in patients treated with a PCSK9 inhibitor compared with placebo. Secondary endpoints were change in other lipids and incidence of adverse events. A random effects model was used to analyze the pooled estimates. Results: A pooled analysis of 9 trials with a total of 1361 patients was performed. Overall the mean difference in LDL-C reduction with PCSK9 inhibition was -48.6% (95% CI: -51.3 to -45.9; p<0.001), as compared with placebo. There was no significant difference in LDL-C reduction between trials using alirocumab vs. those using evolocumab. There was significant heterogeneity among the included trials I 2 =75.9%. The risk of bias in all included studies was low. Conclusions: Among patients with FH, PCSK9 inhibitors were highly effective and reduced LDL-C levels by nearly 50% compared with placebo. No differences in magnitude of reduction were observed between alirocumab and evolocumab.

Abstract Background: A systematic review and meta-analysis was conducted to compare the safety and efficiency of nephroscope and cystoscope in transurethral cystolithotripsy (TUCL) for bladder stones. Methods: PubMed, Web of Science, Embase, EBSCO, and the Cochrane library databases (updated January 2021) were searched for studies that assessed the efficacy of different types of endoscopes in TUCL cases. The search strategy and study selection process was managed according to the PRISMA statement. Results: Five randomized controlled trials were included in the meta-analysis. Our result showed no significant differences in the stone free rate (SFR) across the studies (RR= 1.00; CI 0.98–1.02, p = 1.00). The study heterogeneity (I2 = 0%, P = 1.00) was not significant as all patients were rendered stone free. Using nephroscope can significantly shorten operation times compared to the use of cystoscopy (RR= -26.26; CI -35.84 – -16.68, p < 0.00001) with significant heterogeneity (I2 =87%, p < 0.00001). There was no significant difference between mean urethral entries (RR= 0.66; CI -0.71 – -2.04, p = 0.35), hospitalization (MD = 0.08, 95% CI = -0.07-0.23; P=0.31) and the total complication rate (RR = 1.37, 95% CI = 0.47-4.00, p=0.56). Conclusions: This systematic review demonstrated that using are highly efficient approaches in the clearance of bladder stones and result in a low rate of complication and short hospitalization times. The mean urethral entries are dependent on the treatment method for large stone fragments. However, using nephroscope can significantly reduce operation times.

Background. A substantial proportion of patients undergoing colorectal surgery receive a temporary stoma, and the timing for stoma closure remains unclear. The aim of this study was to evaluate the safety and feasibility of early stoma closure (ESC) compared with routine stoma closure (RSC) after colorectal surgery. Methods. We comprehensively searched PubMed, Embase, and the Cochrane Library for randomized controlled trials that compared ESC and RSC after colorectal surgery. Results. A total of 7 randomized controlled trials with 814 enrolled patients were identified for this meta-analysis. There were no significant differences between the ESC and RSC groups regarding the complications of stoma closure (26.8% and 16.6%, respectively; odds ratio [OR]: 1.30; 95% confidence interval [CI]: 0.89-1.90; P = .17). A subgroup analysis was conducted by Clavien-Dindo grade of complication, and no significant difference was observed in any subgroup ( P > .05). However, the ESC group had a significantly higher risk of wound complications than the RSC group (17.6% and 7.8%, respectively; OR: 2.61; 95% CI: 1.43-4.76; P = .002), and the RSC group had more cases of small bowel obstruction than the ESC group (3.1% and 8.4%, respectively; OR: 0.37; 95% CI: 0.15-0.87; P = .02). Conclusions. ESC is a safe and effective therapeutic approach in patients who have undergone colorectal surgery; it is associated with a reduced risk of bowel obstruction but a higher risk of wound complications.

Virtual reality (VR), a technology that provides a stimulated sensory experience, has recently been implemented in various fields of medicine. Several studies have investigated the efficacy of VR on preoperative anxiety. The purpose of this meta-analysis was to validate whether VR could relieve preoperative anxiety in patients undergoing surgery. Electronic databases were searched to identify all randomized controlled trials (RCTs) investigating the effect of VR on preoperative anxiety. The primary outcome was defined as the preoperative anxiety scores. We estimated the effect size using the standard mean difference (SMD) with a 95% confidence interval (CI) using a random effect model. Ultimately, 10 RCTs, with a total of 813 patients, were included in the final analysis. Preoperative anxiety was significantly lower in the VR group than in the control group (SMD −0.64, 95% CI −1.08 to −0.20, p = 0.004). In a subgroup analysis, the preoperative anxiety scores were lower in the VR group than in the control group in pediatric patients (SMD −0.71, 95% CI −1.14 to −0.27, p = 0.002), whereas a significant difference was not observed between the two groups in adult patients (p = 0.226). The results of this meta-analysis indicated that VR could decrease preoperative anxiety, especially in pediatric patients.

This meta-analysis aims to compare intravenous colistin monotherapy and colistin-based combination therapy against carbapenem-resistant gram-negative bacteria (GNB) infections. PubMed, Embase, and Cochrane databases were searched up to July 2018. Only randomized controlled trials (RCTs) evaluating colistin alone and colistin-based combination therapy in the treatment of carbapenem-resistant GNB infections were included. The primary outcome was all-cause mortality. Five RCTs including 791 patients were included. Overall, colistin monotherapy was associated with a risk ratio (RR) of 1.03 (95% confidence interval (CI), 0.89–1.20, I2 = 0%) for all-cause mortality compared with colistin-based combination therapy. The non-significant difference was also detected in infection-related mortality (RR, 1.23, 95% CI, 0.91–1.67, I2 = 0%) and microbiologic response (RR, 0.86, 95% CI, 0.72–1.04, I2 = 62%). In addition, no significant difference was observed in the subgroup analysis—high or low dose, with or without a loading dose, carbapenem-resistant Acinetobacter baumannii infections, and in combination with rifampicin. Finally, colistin monotherapy was not associated with lower nephrotoxicity than colistin combination therapy (RR, 0.98; 95% CI, 0.84–1.21, I2 = 0%). Based on the analysis of the five RCTs, no differences were found between colistin monotherapy and colistin-based combination therapy against carbapenem-resistant GNB infections, especially for A. baumannii infections.

Vitamin E Supplementation

Abstract Background Chemotherapy often causes chemotherapy-induced peripheral neuropathy (CIPN), but effective prevention measures are still lacking. Whether vitamin E can prevent peripheral neurotoxicity caused by chemotherapy is inconclusive. Therefore, we collected related randomized controlled trials (RCTs) and conducted a meta-analysis to examine whether vitamin E could prevent CIPN. Methods We searched PubMed, EMBASE and the Cochrane databases in November 2019 for eligible trials. Two reviewers conducted the analysis independently when studies were homogeneous enough. Results Eight RCTs, involving 555 patients, were identified. Upon pooling these RCTs, patients who received vitamin E supplementation of 600 mg/day had a significantly lower incidence of peripheral neuropathy (RR 0.31; 95% CI 0.14 to 0.65; P = 0.002) induced by chemotherapy compared with the placebo group. Vitamin E played a key role in decreasing the incidence of peripheral neuropathy in the cisplatin chemotherapy group (RR 0.28; 95% CI 0.14 to 0.54; P = 0.0001). With regard to improvements in sural amplitude, vitamin E supplementation significantly decreased patients’ sural amplitude after three rounds of chemotherapy (RR -2.66; 95% CI -5.09 to -0.24; P =0.03) in contrast with that of placebo supplementation, while no significant difference was observed when patients were treated with vitamin E after six rounds of chemotherapy. In addition, the vitamin E group had better improvement in the neurotoxicity score (RR -2.65; 95% CI -4.01to -1.29; P = 0.0001) and a lower incidence of reflexes and distal paraesthesias (RR 0.50; 95% CI 0.29 to 0.87; P = 0.01) compared to the control group. Conclusion Available data included in this meta-analysis showed that vitamin E supplementation can confer modest improvement in the prevention of CIPN. However, large-scale, well-designed RCTs are needed to confirm the exact role of vitamin E supplementation in the prevention of CIPN.

Objectives. To systematically evaluate the efficacy and safety of sinomenine preparation (SP) for treating ankylosing spondylitis (AS). Methods. Clinical randomized controlled trials (RCTs) of SP for treating AS were systematically identified in six electronic databases including PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP), and Wanfang Databases from the inception up to 31 October 2019. Cochrane’s risk of bias tool was used to assess the methodological quality and Review Manager 5.3 software was used to analyze data. Results. A total of 12 RCTs involving 835 patients were finally included. According to interventions, RCTs were divided into two types. The intervention in 10 RCTs was SP combined with conventional pharmacotherapy (CPT) versus CPT and that in 2 RCTs was SP alone versus CPT. The results of the meta-analysis showed that, compared with CPT alone, SP combined with oral CPT has better improvement in BASDAI (WMD = −1.84, 95% CI [−3.31, −0.37], P=0.01), morning stiffness time (WMD = −13.46, 95% CI [−16.12, −10.79], P<0.00001), the Schober test (WMD = 1.26, 95% CI [0.72, 1.80], P<0.00001), the occipital wall test (WMD = −0.55, 95% CI [−0.96, −0.14], P=0.009), the finger-to-ground distance (WMD = −3.28, 95% CI [−5.64, −0.93], P=0.006), 15 m walking time (WMD = −8.81, 95% CI [−13.42, −4.20], P=0.0002), the C-reactive protein (CRP) (WMD = −1.84, 95% CI [−3.24, −0.45], P=0.01), and the total effective rate (RR = 1.10, 95% CI [1.01, 1.20], P=0.03). Besides, it also showed that oral SP alone may be more effective in improving morning stiffness time (WMD = −31.89, 95% CI [−34.91, −28.87], P<0.00001) compared with CPT alone. However, this study cannot provide evidence that loading the injectable SP based on CPT can significantly increase the efficacy due to the insufficient number of studies included. In terms of adverse events, there was no statistically significant difference between the experimental group and the control group. Conclusions. This study shows that oral SP may be effective and safe in the treatment of AS. Due to the low methodological quality of the included RCTs and the limitations of the meta-analysis, it is still necessary to carry out more multicenter, large-sample, and high-quality RCTs to further verify the conclusions. The review protocol was registered on PROSPERO (CRD42018099170), and the review was constructed following the PRISMA guidelines (Annex 1).
