This study describes a systematic review of the best available evidence on the effectiveness of a chlorhexidine mouth rinse as a mono-therapy or as an adjunct to mechanical oral hygiene against plaque growth and gingival inflammation. Medline, EMBASE and the Cochrane Central register of Controlled Trials were searched up to April 2011. Randomised controlled clinical trials that compared chlorhexidine to placebo or controlled mouth rinses or regular oral hygiene for a minimum duration of at least four weeks amongst gingivitis patients (≥ 18 years of age) were included. A total of 30 publications fulfilled the selection criteria. Clinical parameters measured at baseline and end of trial were plaque, gingival inflammation, bleeding and staining. Chlorhexidine reduced plaque by 33% and gingivitis by 26% compared to a placebo or a control mouth rinse. The investigators concluded that when used together with oral hygiene, chlorhexidine mouth rinses provide significant reductions in plaque and gingivitis scores in gingivitis patients, but a significant increase in staining compared to placebo or control mouth rinses.

125 Background: Despite the successful integration of targeted therapies, chemotherapy remains the mainstay of treatment for mAGC. Uncertainty remains regarding the choice of the regimen. Methods: We searched: Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE until February 2014; proceedings from ECCO, ESMO, ASCO until June 2014 with Selection criteria: Randomised controlled trials on chemotherapy in mAGC. Objectives: To assess and compare the effects on overall survival of regimens containing: 1) irinotecan (I) vs non-I, 2) docetaxel (D) vs non-D, 3) capecitabine (C) vs 5-FU, 4) S-1 vs 5-FU, 5) oxaliplatin (O) vs the same regimen containing cisplatin. For 1) and 2), substitutive (other chemotherapy substituted by I or D) and additive comparisons (I or D added) were analyzed separately. Results: The meta-analyses of overall survival included: Comparison 1) a. Substitutive: 5 trials, 724 patients (pts), with a HR of 0.85 (95% CI 0.73-0.99), b. Additive: 3 trials, 500 pts, with a HR of 0.88 (95% CI 0.76-1.03), both in favor of the I-containing regimens. Comparison 2) In total, 6 trials, 1702 pts, with a HR of 0.89 (95% CI 0.80-0.99) in favor of patients treated with D. a. Substitutive: 3 trials, 479 pts, with a HR of 1.05 (95% CI 0.87-1.27) in favor of patients treated without D. b. Additive: 3 trials, 1223 pts, with a HR of 0.82 (95% CI 0.87-0.93), in favor of D-containing regimens. If only studies (2 trials, 588 pts) are considered, in which D is added to a platinum/5-FU doublet, the HR is 0.79 (95% CI 0.64-0.98) in favor of the D-containing regimen. Comparison 3) 2 trials, 401 pts, with a HR of 0.85 (95% CI 0.68-1.06) in favor of the C-containing-regimen. Comparison 4) 2 trials, 1497 pts, with a HR of 0.89 (95% CI 0.80-1.0) in favor of the S-1-containing regimen. Comparison 5) 1 trial, 220 pts, with a HR of 0.82 (0.47-1.45) in favor of the O-containing regimen. Conclusions: All different chemotherapy combinations including I, D, O or oral 5-FU prodrugs are valid treatment options for mAGC. Among the comparisons analyzed above, only D-containing combinations, in which D was added to a single-agent or two-drug (platinum/5-FU) combination show a significant advantage in overall survival as compared to regimens without D.

Background Glenohumeral joint instability is associated with structural deficits and/or alterations in sensory and motor processing; however, a proportion of patients with glenohumeral joint instability fail to respond to surgical and rehabilitative measures. This systematic review aimed to establish if functional cortical changes occur in patients with glenohumeral joint instability. Methods AMED, CINAHL, Cochrane Central Register of Controlled Trials, Embase, Medline, PEDro, Pubmed, PsychINFO and Scopus were searched from inception to 17 March 2021. Randomised controlled trials and non-randomised trials were included and quality was appraised using the Downs and Black tool. Results One thousand two hundred seventy-nine records were identified of which five were included in the review. All studies showed altered cortical function when comparing instability patients with healthy controls and included areas associated with higher cortical functions. Discussion The findings of this systematic review offer some insight as to why interventions addressing peripheral pathoanatomical factors in patients with glenohumeral joint instability may fail in some cases due to functional cortical changes. However, data are of moderate to high risk of bias. Further high-quality research is required to ascertain the degree of functional cortical changes associated with the type and duration of glenohumeral joint instability.

BackgroundOptimal fluid resuscitation in children with major burns is crucial to prevent or minimise burn shock and prevent complications of over-resuscitation.ObjectivesTo identify studies using endpoints to guide fluid resuscitation in children with burns, review the range of reported endpoint targets and assess whether there is evidence that targeted endpoints impact on outcome.DesignSystematic review.MethodsMedline, Embase, Cinahl and the Cochrane Central Register of Controlled Trials databases were searched with no restrictions on study design or date. Search terms combined burns, fluid resuscitation, endpoints, goal-directed therapy and related synonyms. Studies reporting primary data regarding children with burns (<16 years) and targeting fluid resuscitation endpoints were included. Data were extracted using a proforma and the results were narratively reviewed.ResultsFollowing screening of 777 unique references, 7 studies fulfilled the inclusion criteria. Four studies were exclusively paediatric. Six studies used urine output (UO) as the primary endpoint. Of these, one set a minimum UO threshold, while the remainder targeted a range from 0.5–1.0 mL/kg/hour to 2–3 mL/kg/hour. No studies compared different UO targets. Heterogeneous study protocols and outcomes precluded comparison between the UO targets. One study targeted invasive haemodynamic variables, but this did not significantly affect patient outcome.ConclusionsFew studies have researched resuscitation endpoints for children with burns. Those that have done so have investigated heterogeneous endpoints and endpoint targets. There is a need for future randomised controlled trials to identify optimal endpoints with which to target fluid resuscitation in children with burns.

ObjectiveOver half of patients with IBS have either diarrhoea (IBS-D) or a mixed stool pattern (IBS-M). The relative efficacy of licenced pharmacological therapies is unclear in the absence of head-to-head trials. We conducted a network meta-analysis to resolve this uncertainty.DesignWe searched MEDLINE, Embase, Embase Classic, the Cochrane central register of controlled trials, and Clinicaltrials.gov through January 2019 to identify randomised controlled trials (RCTs) assessing the efficacy of licenced pharmacological therapies (alosetron, eluxadoline, ramosetron and rifaximin) in adults with IBS-D or IBS-M. Trials included in the analysis reported a dichotomous assessment of overall response to therapy, and data were pooled using a random effects model. Efficacy and safety of all pharmacological therapies were reported as a pooled relative risk with 95% CIs to summarise the effect of each comparison tested. Treatments were ranked according to their p score.ResultsWe identified 18 eligible RCTs (seven alosetron, five ramosetron, two rifaximin and four eluxadoline), containing 9844 patients. All were superior to placebo for the treatment of IBS-D or IBS-M at 12 weeks, according to the Food and Drug Administration (FDA)-recommended endpoint for trials in IBS. Alosetron 1 mg twice daily was ranked first for efficacy, based on the FDA-recommended composite endpoint of improvement in both abdominal pain and stool consistency, effect on global symptoms of IBS and effect on stool consistency. Ramosetron 2.5µg once daily was ranked first for effect on abdominal pain. Total numbers of adverse events were significantly greater with alosetron 1 mg twice daily and ramosetron 2.5µg once daily, compared with placebo. Rifaximin 550 mg three times daily ranked first for safety. Constipation was significantly more common with all drugs, except rifaximin 550 mg three times daily.ConclusionIn a network meta-analysis of RCTs of pharmacological therapies for IBS-D and IBS-M, we found all drugs to be superior to placebo, but alosetron and ramosetron appeared to be the most effective.

Objective. The aim of the review was to compare the use of finasteride to placebo in patients undergoing TURP procedures. Material & Methods. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (1966–November 2011), EMBASE (1980–November 2011), CINAHL, Clinicaltrials.gov, Google Scholar, reference lists of articles, and abstracts from conference proceedings without language restriction for studies comparing finasteride to placebo patients needing TURPs. Results. Four randomised controlled trials were included comparing finasteride to a placebo. A meta-analysis was not conducted due to the disparity present in the results between the studies. Three of the studies found that finasteride could reduce either intra- or postoperative bleeding after TURP. One study found finasteride to significantly lower the microvessel density (MVD) and vascular endothelial growth factor (VEGF). None of the studies reported any long-term complications related to either the medication or the procedure. Conclusion. finasteride reduces bleeding either during or after TURP.

Abstract Primaquine was the only licenced antimalarial hypnozoiticidal drug available until recently. Now there is a newly approved alternative: tafenoquine. This review explores the efficacy of tafenoquine as a primary and terminal prophylactic agent in malaria. Multiple databases (Cochrane Central Register of Controlled Trials [CENTRAL], MEDLINE [PubMed], Embase [Ovid], Scopus, CINAHL [EBSCOhost] and LILACS) were searched for clinical randomised controlled trials that had used tafenoquine for prophylaxis without language or time restrictions. The last date of searching was 13 August 2018. For primary prophylaxis, tafenoquine reduced episodes of malaria compared with placebo, at a dose range from 50 mg weekly to 400 mg monthly in three trials conducted in Ghana, Kenya and Thailand. Two trials compared tafenoquine vs mefloquine, but malaria episodes were too few to reach a conclusion. For terminal prophylaxis, evidence from two trials suggest that tafenoquine may have equal or better efficacy compared with primaquine. All trials excluded pregnant participants or those with G6PD deficiency. Tafenoquine is effective for both primary and terminal prophylaxis. If used for primary prophylaxis it may continue to offer protection against vivax relapses after exposure has ended (as terminal prophylaxis).

4555 Background: Combination chemotherapy is widely accepted for patients with advanced gastric cancer, but uncertainty remains regarding the choice of the regimen. Methods: Our objectives were to assess the effect of: 1) 5-FU/cisplatin combinations with versus without anthracyclines; 2) 5-FU/anthracycline combinations with versus without cisplatin; 3) Irinotecan versus non-irinotecan containing combination chemotherapies; 4) Docetaxel versus non-docetaxel containing combinations; on overall survival and toxicity. Search strategy: We searched: Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, proceedings from DDW, ECCO, ESMO, ASCO until october 2006. Selection criteria: Randomised controlled trials on different combination chemotherapies as above in advanced gastric cancer. Results: 13 trials including in total 2,184 patients (pts) are included in this meta-analysis. Comparison 1) including 501 pts (HR 0.77; 95% CI 0.62–0.95); and 2) including 1,147 pts (HR 0.83; 95%CI 0.76–0.91) both demonstrate a significant survival benefit for three-drug regimens including 5-FU, anthracyclines and cisplatin. Among these, the rate of treatment-related deaths was higher when 5-FU was administered as bolus compared to infusional 5-FU (exact Mantel-Haenszel OR 2.33, p=0.285). Comparison 3) including 536 pts results in a HR of 0.88; 95% CI 0.73- 1.06. The rate of treatment related deaths was 0.7% versus 2.6% in the irinotecan versus non-irinotecan-containing arms (exact Mantel-Haenszel OR 0.275, p=0.166). Comparison 4) 4 relevant trials were identified. A meta-analysis will be performed as soon as the final results of at least 3 trials are available. Conclusions: Three-drug regimens containing 5-FU, anthracyclines and cisplatin achieve superior survival results compared to cisplatin/5-FU or antracycline/5-FU combinations. Among these, ECF (epirubicin, cisplatin and 5-FU) is tolerated best. Combinations including irinotecan demonstrate a non-significant trend towards better survival in this meta-analysis, but have never been compared against three-drug regimens containing 5-FU/cisplatin and an anthracycline.

Abstract Background Lambert-Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder of neuromuscular transmission. The objective was to examine the efficacy and safety of 3,4-diaminopyridine (3,4-DAP) in patients with LEMS. Methods We searched several databases to identify relevant studies, including PubMed, EMBASE, Web of Science, MEDLINE, Cochrane Neuromuscular Disease Group Specialized Register and the Cochrane Central Register of Controlled Trials(CENTRAL). The primary outcome, quantitative myasthenia gravis (QMG) score and the secondary outcome, compound muscle action potentials (CMAP) amplitude were pooled by meta-analysis. Results Six randomised controlled trials (RCTs) involving 115 patients with LEMS were included. QMG score showed a significant decrease (improvement) of 2.76 points (95 % CI, -4.08 to -1.45, p < 0.001) after treatment with 3, 4-DAP. Moreover, the overall mean CMAP amplitude improved significantly in LEMS patients with 3, 4-DAP treatment, compared with placebo treatment (mean difference 1.34 mV, 95 % CI, 0.98 to 1.70, p < 0.001). The overall assessment of all included trials showed a low risk of bias and low heterogeneity. Conclusions The pooled results of RCTs demonsrated with moderate to high evidence that 3,4-DAP has a significant effect on LEMS treatment, with improvements in muscle strength score and CMAP amplitude.

BackgroundThe prevalence of obesity is increasing globally and this could partly explain the worldwide increase in the prevalence of atrial fibrillation (AF), as both overweight and obesity are established risk factors. However, the relationship between weight change and risk of incident AF, independent of starting weight, remains uncertain.MethodsMEDLINE, Embase, Pubmed, Web of Science, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, Trials Register—clinicaltrials.gov, CINAHL and the WHO ICTRP were searched from inception to July 2018.We included randomised controlled trials and cohort studies across all healthcare settings but excluded studies of bariatric surgery. A random effects model was used to calculate pooled hazard ratios. The primary outcome was the risk of incident AF in relation to weight change.ResultsTen studies, including 108 996 people, met our inclusion criteria. For a 5% gain in weight, the incidence of AF increased by 13% (HR 1.13, 95% CI 1.04 to 1.23, I2=70%, n>20 411 in five studies; study size was unknown for one study). A 5% loss in body weight was not associated with a significant change in the incidence of AF (HR 1.04, 95% CI 0.94 to 1.16, I2=73%, n=40 704 in five studies).ConclusionsWeight gain may increase the risk of AF, but there was no clear evidence that non-surgical weight loss altered AF incidence. Strategies to prevent weight gain in the population may reduce the global burden of AF. Given the lack of studies and methodological limitations, further research is needed.

IntroductionOesophageal cancer is one of the most common malignant tumours and has been identified as one of the leading causes of cancer death worldwide. Surgery is considered to be the optimal treatment for patients with resectable oesophageal cancer. Oesophagectomy for oesophageal cancer can significantly extend the survival period of patients and provide a potential opportunity for a cure. However, there is still controversy regarding which thoracic approach (right or left) during oesophagectomy for oesophageal cancer can lead to better surgical outcomes globally. This systematic review and meta-analysis will be performed to determine which thoracic approach during oesophagectomy will achieve longer patient survival and will be more beneficial for patients.Methods and analysisWe will search PubMed, Web of Science, Embase, Cancerlit, the Cochrane Central Register of Controlled Trials and Google Scholar databases for relevant clinical trials published in any language before 1 October 2019. Randomised controlled trials (RCTs), quasi-RCTs, propensity score-matched comparative studies and prospective cohort studies of interest, published or unpublished, that meet the inclusion criteria will be included. Subgroup analysis of the type of operation, tumour pathological stage and ethnicity will be performed.PROSPERO registration numberCRD42019124133.Ethics and disseminationBecause this study will be based on published or unpublished records and studies, there is no need for ethics approval. The results of the study will be published in a peer-reviewed journal.
