Patients who undergo abdominal surgery under general anesthesia develop hypothermia in 80–90% of the cases within an hour after induction of anesthesia. Side effects include shivering, bleeding, and infection at the surgical site. However, the surgical team applies forced air warming to prevent peri-operative hypothermia, but these methods are insufficient. This study aimed to confirm the optimal application method of forced air warming (FAW) intervention for the prevention of peri-operative hypothermia during abdominal surgery. A systematic review and meta-analysis were conducted to provide a synthesized and critical appraisal of the studies included. We used PubMed, EMBASE, CINAHL, and Cochrane Library CENTRAL to systematically search for randomized controlled trials published through March 2020. Twelve studies were systematically reviewed for FAW intervention. FAW intervention effectively prevented peri-operative hypothermia among patients undergoing both open abdominal and laparoscopic surgery. Statistically significant effect size could not be confirmed in cases of only pre- or peri-operative application. The upper body was the primary application area, rather than the lower or full body. These findings could contribute detailed standards and criteria that can be effectively applied in the clinical field performing abdominal surgery.

The role of adjuvant transarterial chemoembolization (TACE) for patients with resectable hepatocellular carcinoma (HCC) undergoing hepatectomy is currently unclear. We performed a systematic review of the literature using the MEDLINE, Embase, and Cochrane Library databases. Random-effects meta-analysis was carried out to compare the overall survival (OS) and recurrence-free survival (RFS) of patients with resectable HCC undergoing hepatectomy followed by adjuvant TACE vs. hepatectomy alone in randomized controlled trials (RCTs). The risk of bias was assessed using the Risk of Bias 2.0 tool. Meta-regression analyses were performed to explore the effect of hepatitis B viral status, microvascular invasion, type of resection (anatomic vs. parenchymal-sparing), and tumor size on the outcomes. Ten eligible RCTs, reporting on 1216 patients in total, were identified. The combination of hepatectomy and adjuvant TACE was associated with superior OS (hazard ratio (HR): 0.66, 95% confidence interval (CI): 0.52 to 0.85; p < 0.001) and RFS (HR: 0.70, 95% CI: 0.56 to 0.88; p < 0.001) compared to hepatectomy alone. There were significant concerns regarding the risk of bias in most of the included studies. Overall, adjuvant TACE may be associated with an oncologic benefit in select HCC patients. However, the applicability of these findings may be limited to Eastern Asian populations, due to the geographically restricted sample. High-quality multinational RCTs, as well as predictive tools to optimize patient selection, are necessary before adjuvant TACE can be routinely implemented into standard practice.

ABSTRACT The aim of this study was to determine the effect of zinc supplementation on anthropometric measures. In this systematic review and dose–response meta-analysis, we searched PubMed, Scopus, ISI Web of Science, and the Cochrane Library from database inception to August 2018 for relevant randomized controlled trials. Mean differences and SDs for each outcome were pooled using a random-effects model. Furthermore, a dose–response analysis for zinc dosage was performed using a fractional polynomial model. Quality of evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. Twenty-seven trials (n = 1438 participants) were included in the meta-analysis. There were no significant changes in anthropometric measures after zinc supplementation in the overall analysis. However, subgroup analyses revealed that zinc supplementation increased body weight in individuals undergoing hemodialysis (HD) [3 trials, n = 154 participants; weighted mean difference (WMD) = 1.02 kg; 95% CI: 0.38, 1.65 kg; P = 0.002; I2 = 11.4%] and decreased body weight in subjects who are overweight/obese but otherwise healthy (5 trials, n = 245 participants; WMD = −0.55 kg; 95% CI: −1.06, −0.04 kg; P = 0.03; I2 = 31.5%). Dose–response analyses revealed a significant nonlinear effect of supplementation dosage on BMI (P = 0.001). Our data suggest that zinc supplementation increases body weight in patients undergoing HD and decreases body weight in individuals who are overweight/obese but otherwise healthy, although after normalization for study duration, the association observed in subjects who are overweight/obese disappeared. Although more high-quality studies are needed to reach a definitive conclusion, our study supports the view that zinc may be associated with body weight.

Abstract Purpose The purpose of the systematic review and meta-analysis is to analyze the application value of the stoma support rods in loop enterostomy. Methods The studies on the application of stoma rods in loop enterostomy published from January 2000 to January 2020 were searched in the databases of PubMed, Embase, Cochrane library, and Clinical trials. All randomized controlled trials (RCTs) and cohort studies that observed the value of stoma rods were included according to inclusion criteria. The RevMan5.3 software was used for statistical analysis. Results A total of 1131 patients with loop enterostomy in six studies were included in this study; there were 569 cases in the experimental group and 562 cases in the control group. All six studies analyzed the effect of support rods on the incidence of stoma retraction; the meta-analysis showed that in a total of 32 patients, stoma retraction occurred, with a total incidence of about 2.8% in 1131 patients. The incidence of stoma retraction in the rod group was not significantly lower than that in the non-rod group, and the difference was not statistically significant (OR = 0.65, 95% CI 0.32~1.32, I2 = 0%, P = 0.23), and the studies were homogeneous. The incidences of stoma necrosis (OR = 6.41, 95% CI 2.22~18.55, I2 = 0%, P = 0.0006), peristomal dermatitis (OR = 2.93, 95% CI 2.01~4.27, I2 = 0%, P < 0.00001), and mucocutaneous separation (OR = 2.14, 95% CI 1.03~4.47, I2 = 0%, P = 0.04) were significantly increased in the rod group. Conclusions It is not recommended to routinely use stoma support rods in the clinical practice.

Abstract Background Bendamustine is a chemotherapeutic drug with structural similarities to both alkylating agents (nitrogen mustard derivative) and purine analogues (benzimidazole ring). Theoretically, due to its nucleoside-like properties it might be associated with more infections. Data in the literature is lacking regarding the infection-related adverse events of bendamustine-containing regimens. Thus, we aimed to assess this risk. Methods Systematic review and meta-analysis of all randomized controlled trials comparing bendamustine containing regimens (alone or combined with other chemotherapeutic agents and/or rituximab) to any other regimens. Trials evaluating bendamustine for any indication (hematological as well as solid malignancies) were included.  A comprehensive search of The Cochrane Library, MEDLINE, conference proceedings and references was conducted until July 2013. Two reviewers appraised the quality of trials and extracted data. Outcomes assessed were: any infections, grade 3-4 infections, fatal infections, grade 3-4 neutropenia and grade 3-4 lymphopenia. For dichotomous data, relative risks (RR) with 95% confidence intervals (CIs) were estimated and pooled. We used fixed effect model to pool data, unless there was significant heterogeneity, in which case we used the random effects model. Results Ten trials conducted between the years 1998 and 2013 and randomizing 2360 patients were included. We included 4 trials of patients with non-Hodgkin lymphoma (Rummel 2013, Rummel 2010, Herold 2006 and the Bright study 2013), 3 trials of CLL (Knauf 2009, Niederle 2013, LeBlond 2013), 1 trial of patients with multiple myeloma (Ponish 2006) and 2 trials of breast carcinoma patients. The bendamustine arm included: bendamustine alone (2 trials), bendamustine-rituximab (BR) (4 trials), bendamustine, vincristine, prednisone (BOP) (1 trial), bendamustine, MTX. 5FU (BMF) (2 trials) and bendamustine, prednisone (BP) (1 trial). The comparator arms in 8 of the trials included other alkylating agents: chlorambucil, R -CHOP,  cyclophosphamide, MTX, 5-FU (CMF) and melphalan-prednisone (MP) – each regimen used in 2 trials and COP used in 1 trial.  In 2 trials the comparator arm included fludarabine based regimens (alone or with rituximab). There was no statistically significant effect for bendamustine on the rate of any type of infection (RR 1.06 [95% CI 0.83, 1.34], 6 trials, figure). This analysis included only trials of hematological malignancies. There was no increase in the rate of grade 3-4 infections (RR 1.45 [95% CI 0.86, 2.45], 7 trials) or fatal infection (RR 0.69 [95% CI 0.30, 1.58], 3 trials). Data were too scarce to analyze by specific types of infections separately. There was no increase in the rate of grade 3-4 neutropenia in the bendamustine arm (RR 0.9 [95% CI 0.58, 1.42], 6 trials). This was true both when the comparator was alkylating agent containing regimens (RR 0.87 [95% CI 0.52, 1.48], 4 trials) or fludarabine containing regimens (RR 1.02 [95% CI 0.54, 1.91], 2 trials). There was a significant increase in grade 3-4 lymphopenia in the bendamustine arm compared to alkylating agent containing regimens (RR 1.95[95% CI 1.54, 2.47). Conclusions Our systematic review demonstrates no effect of bendamustine on the rate of infections when compared to either alkylating agents or fludarabine,  in hematological as well as in solid malignancies, despite an increase in lymphopenia. Thus, bendamustine remains a safe therapeutic option. The main drawback of this meta-analysis is the heterogeneity between malignancies and treatments. Disclosures: No relevant conflicts of interest to declare.

Background: Crohn disease (CD) is a chronic inflammatory disease that affects quality of life. There are several drugs available for the treatment of CD, but their relative efficacy is unknown due to a lack of high-quality head-to-head randomized controlled trials.Aim: To perform a mixed comparison of the efficacy and safety of biosimilars, biologics and JAK1 inhibitors for CD.Methods: We searched PubMed, Web of Science, embase and the Cochrane Library for randomized controlled trials (RCTs) up to Dec. 28, 2020. Only RCTs that compared the efficacy or safety of biosimilars, biologics and JAK1 inhibitors with placebo or another active agent for CD were included in the comparative analysis. Efficacy outcomes were the induction of remission, maintenance of remission and steroid-free remission, and safety outcomes were serious adverse events (AEs) and infections. The Bayesian method was utilized to compare the treatments. The registration number is CRD42020187807.Results: Twenty-eight studies and 29 RCTs were identified in our systematic review. The network meta-analysis demonstrated that infliximab and adalimumab were superior to certolizumab pegol (OR 2.44, 95% CI 1.35–4.97; OR 2.96, 95% CI 1.57–5.40, respectively) and tofacitinib (OR 2.55, 95% CI 1.27–5.97; OR 3.10, 95% CI 1.47–6.52, respectively) and revealed the superiority of CT-P13 compared with placebo (OR 2.90, 95% CI 1.31–7.59) for the induction of remission. Infliximab (OR 7.49, 95% CI 1.85–34.77), adalimumab (OR 10.76, 95% CI 2.61–52.35), certolizumab pegol (OR 4.41, 95% CI 1.10–21.08), vedolizumab (OR 4.99, 95% CI 1.19–25.54) and CT-P13 (OR 10.93, 95% CI 2.10–64.37) were superior to filgotinib for the maintenance of remission. Moreover, infliximab (OR 3.80, 95% CI 1.49–10.23), adalimumab (OR 4.86, 95% CI 1.43–16.95), vedolizumab (OR 2.48, 95% CI 1.21–6.52) and CT-P13 (OR 5.15, 95% CI 1.05–27.58) were superior to placebo for steroid-free remission. Among all treatments, adalimumab ranked highest for the induction of remission, and CT-P13 ranked highest for the maintenance of remission and steroid-free remission.Conclusion: CT-P13 was more efficacious than numerous biological agents and JAK1 inhibitors and should be recommended for the treatment of CD. Further head-to-head RCTs are warranted to compare these drugs.

Abstract Objective: The aim of this review was to evaluate the efficacy and tolerability of ubrogepant in patients with acute migraine. Methods: We systematically searched PubMed, Embase, MEDLINE, Cochrane Library, and clinicaltrials.gov from inception to JULY, 2019. Randomized controlled trials of the efficacy and/or tolerability of ubrogepant for migraine were included. Meta-analysis was conducted by RevMan 5.3 software. Results: A total of 4 RCTs involving 4 163 patients were included. The meta-analysis showed that:compared to the control group, the percentage of participants with PF, the percentage of participants with PR, the percentage of participants with SPF, the percentage of participants with SPR,the absence of phonophobia in sound,the absence of phonophobia in light and the absence of nausea (RR=1.31,95%CI:1.18~1.45,P<0.00001, RR=1.63,95%CI:1.46~1.82,P<0.00001, RR=1.22,95%CI:1.15~1.29,P<0.00001, RR=1.32,95%CI:1.22~1.42,P<0.00001, RR=1.16,95%CI:1.05~1.27,P=0.002), all the differences were statistically significant. Conclusions: For adult patients with acute migraine, ubrogepant could effectively abort the acute attack. High-quality, adequately powered RCTs are needed to fully evaluate the efficacy and tolerability of ubrogepant for acute migraine.
