Introduction: Patients diagnosed with heart failure in primary care have a better prognosis than those diagnosed in hospital. However, most cases are missed in the community. Recent attention has focussed on the potential of early detection through screening. Natriuretic peptides (NPs) are tested by GPs and used to rule out heart failure in patients presenting with symptoms. Evidence is now emerging that they may also have a role in screening but their accuracy in this context and the associated optimal thresholds, have not been established. The impact that NP screening would have on patients and health care systems also remains unclear. Methods: We aim to undertake a systematic search of the following sources: Ovid Medline, Embase, Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Trials. Screening, data extraction and critical appraisal will be carried out independently and in duplicate by two reviewers. We will include studies based in the community with >100 participants that recruited a screened population. We will not add a study design filter and there will be no language restriction. The primary outcome will be the sensitivity and the specificity of NP screening and optimal thresholds for screening will be explored. Outcomes of interest for the impact analysis will include mortality, hospital admissions and cost effectiveness. This protocol has been developed in accordance with guidelines from the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P). Discussion: This systematic review will identify how accurately NP screen for heart failure in the community and explore where NP screening thresholds should be set. It also aims to summarise the clinical impact of this strategy. Together, these results should inform future interventions that may provide an alternative pathway to facilitate improved detection of heart failure in the community.

ObjectiveTo assess the impact of adjunctive antibiotic therapy on uncomplicated skin abscesses.DesignSystematic review and network meta-analysis.Data sourcesMedline, Embase, the Cochrane Central Register of Controlled Trials and ClinicalTrials.gov.Study selectionA BMJ Rapid Recommendation panel provided input on design, important outcomes and the interpretation of the results. Eligible randomised controlled trials (RCTs) included a comparison of antibiotics against no antibiotics or a comparison of different antibiotics in patients with uncomplicated skin abscesses, and reported outcomes prespecified by the linked guideline panel.Review methodsReviewers independently screened abstracts and full texts for eligibility, assessed risk of bias and extracted data. We performed random-effects meta-analyses that compared antibiotics with no antibiotics, along with a limited number of prespecified subgroup hypotheses. We also performed network meta-analysis with a Bayesian framework to compare effects of different antibiotics. Quality of evidence was assessed with The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.ResultsFourteen RCTs including 4198 patients proved eligible. Compared with no antibiotics, antibiotics probably lower the risk of treatment failure (OR 0.58, 95% CI 0.37 to 0.90; low quality), recurrence within 1 month (OR 0.48, 95% CI 0.30 to 0.77; moderate quality), hospitalisation (OR 0.55, 95% CI 0.32 to 0.94; moderate quality) and late recurrence (OR 0.64, 95% CI 0.48 to 0.85; moderate quality). However, relative to no use, antibiotics probably increase the risk of gastrointestinal side effects (trimethoprim and sulfamethoxazole (TMP-SMX): OR 1.28, 95% CI 1.04 to 1.58; moderate quality; clindamycin: OR 2.29, 95% CI 1.35 to 3.88; high quality) and diarrhoea (clindamycin: OR 2.71, 95% CI 1.50 to 4.89; high quality). Cephalosporins did not reduce the risk of treatment failure compared with placebo (moderate quality).ConclusionsIn patients with uncomplicated skin abscesses, moderate-to-high quality evidence suggests TMP-SMX or clindamycin confer a modest benefit for several important outcomes, but this is offset by a similar risk of adverse effects. Clindamycin has a substantially higher risk of diarrhoea than TMP-SMX. Cephalosporins are probably not effective.

Respiratory Rehabilitation

IntroductionBoth physical and mental disorders may be exacerbated in patients with COVID-19 due to the experience of receiving intensive care; undergoing prolonged mechanical ventilation, sedation, proning and paralysis. Pulmonary rehabilitation is aimed to improve dyspnoea, relieve anxiety and depression, reduce the incidence of related complications, as well as prevent and improve dysfunction. However, the impact of respiratory rehabilitation on discharged patients with COVID-19 is currently unclear, especially on patients who have been mechanically ventilated over 24 hours. Therefore, we aim to investigate the efficacy of respiratory rehabilitation programmes, initiated after discharge from the intensive care unit, on the physical and mental health and health-related quality of life in critical patients with COVID-19.Methods and analysisWe have registered the protocol on PROSPERO and in the process of drafting it, we strictly followed the checklist of Preferred Reporting Items for Systematic Review and Meta-Analysis Potocols. We will search the PubMed, EMBASE, Web of Science, the Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, WanFang, VIP information databases and Chinese Biomedical Literature Database. Additionally, ongoing trials in the WHO International Clinical Trials Registry Platform, ClinicalTrials.gov and ISRCTN registry will be searched as well. Studies in English or Chinese and from any country will be accepted regardless of study design. Two review authors will independently extract data and assess the quality of included studies. Continuous data are described as standard mean differences (SMDs) with 95% CIs. Dichotomous data from randomised controlled trials are described as risk ratio(RR) with 95% CIs; otherwise, it is described as odds ratio(OR) with 95% CIs. I2 and the Cochrane’s Q statistic will be used to conduct heterogeneity assessment. The quality of evidence of main outcomes will be evaluated according to the Grading of Recommendations, Assessment, Development and Evaluation(GRADE) criteria. When included studies are sufficient, we will conduct subgroup analysis and sensitivity analysis; the publication bias will be statistically analysed using a funnel plot analysis and Egger’s test.Ethics and disseminationOur review, planning to include published studies, does not need the request to the ethical committee. The final results of this review will be published in a peer-reviewed journal after completion.Patient and public involvementNo patient involved.PROSPERO registration numberCRD42020186791.

<b><i>Introduction:</i></b> Several studies have implicated the PIK3/AKT pathway in the pathophysiology of cancer progression as its activation seems to be aberrant in several forms of cancer. The purpose of the present systematic review is to evaluate the impact of PIK3CA mutations on survival outcomes of patients with cervical cancer. <b><i>Methods:</i></b> We used the Medline (1966–2020), Scopus (2004–2020), ClinicalTrials.gov (2008–2020), EMBASE (1980–2020), Cochrane Central Register of Controlled Trials (CENTRAL) (1999–2020), and Google Scholar (2004–2020) databases in our primary search along with the reference lists of electronically retrieved full-text papers. Statistical meta-analysis was performed with the RevMan 5.3 software. <b><i>Results:</i></b> Overall, 12 articles were included in the present study that comprised 2,196 women with cervical cancer. Of those, 3 studies did not report significant differences in survival outcomes among patients with mutated versus wild-type PIK3CA tumors, 5 studies reported decreased survival outcomes, and 3 studies revealed increased survival rates. The meta-analysis revealed that patients with the mutated PIK3CA genotypes had worse overall survival compared to patients with wild-type PIK3CA (HR 2.31; 95% CI: 1.51, 3.55; 95% PI: 0.54, 9.96; data from 3 studies) and the same was observed in the case of DFS rates (HR 1.82; 95% CI: 1.47, 2.25; 95% PI: 1.29, 2.56; data from 4 studies). <b><i>Conclusion:</i></b> Current evidence concerning the impact of PIK3CA mutations on survival outcomes of patients with cervical cancer is inconclusive, although the majority of included studies support a potential negative effect, primarily among those with squamous cell carcinoma tumors.

Abstract Background and Aims Interest in histology for ulcerative colitis [UC] has increased recently. This systematic review and meta-analysis aims to assess, for the first time, whether histological outcomes are more informative than endoscopic and clinical outcomes in distinguishing the impact of intervention over placebo in induction trials. Methods MEDLINE, ScienceDirect and Cochrane Central Register of Controlled Trials were searched to identify randomized placebo-controlled trials [RCTs] enrolling moderate-to-severe UC patients. Studies were assessed using the Quality Assessment Tool for Studies with Diverse Designs. We analysed the pooled proportion of patients achieving clinical, endoscopic and histological remission and response after a pharmacological intervention and compared the results with those of placebo-treated patients by using a random-effects model. Results From 889 identified records, 13 RCTs were included. The odds ratio [OR] for remission was higher in patients receiving intervention than in those under placebo for clinical (OR 2.13, 95% confidence interval [CI] 1.33–3.43), endoscopic [OR 1.46, 95% CI 0.19–11.18] and histological remission [OR 1.85, 95% CI 1.20–2.84]. Significant differences were observed for all response outcomes [clinical: OR 2.27, 95% CI 1.84–2.85; endoscopic: OR 2.16, 95% CI 1.51–3.10; histological: OR 3.63, 95% CI, 1.41–9.36]. No significant heterogeneity existed; no subgroup effects were found for duration of the induction or histological scale [p &gt; 0.05]. Clinical and histological remission and endoscopic response were concordant in discriminating interventions from placebo. Conclusion Histological outcomes are informative in trials of moderate-to-severe UC. Further studies analysing histology at the end of induction are needed to confirm its relevance in distinguishing the efficacy of an intervention over placebo in comparison to clinical and endoscopic outcomes and to explore its prognostic value.

The Impact

IntroductionGenerally, complete resection with cancer cell negative (R0) margin has been accepted as the most effective treatment of gastric cancer and positive resection (R1/R2) margin has been associated with decreased survival to varied degrees. However, the independent impact of microscopical positive (R1) margin on long-term survival may be confounded. No meta-analysis has worked at the association between R1 margin and outcomes of gastric cancer and the available evidence are scant. Therefore, we plan to conduct a systematic review and meta-analysis to quantitatively explore the role of R1 margin on gastric (including oesophagogastric junction) cancer survival after curative intent resection.Methods and analysisThe protocol was conducted according to Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guideline. A systematic search of PubMed, Embase and the Cochrane Central Register of Controlled Trials databases will be performed from their inceptions to 30 April 2020 to identify randomised controlled trials (RCTs), cohort studies and case–control studies focusing on the impact of R1 margin on survival of gastric cancer after curative intent resection. The primary outcome will be the overall survival (OS) and disease-free survival (DFS) and the secondary outcomes will be 5-year OS rate and 5-year DFS rate. The Cochrane tool for bias assessment in randomised trials and Risk Of Bias In Non-randomised Studies-I for the assessment of bias in non-randomised studies (NRS) will be used. Statistical heterogeneity will be assessed by visual inspection of forest plots and measured using the I2 statistics. A fixed-effect model will be used when heterogeneity is low, otherwise, a random-effect model will be chosen. Publication bias will be assessed by funnel plots, subgroup analysis and sensitivity analysis will be performed in the right context. For each outcome, we will perform data synthesis separately for RCTs and NRS using Rev Man V.5.3 software and compile ‘summary of findings’ tables separately for RCTs and NRS using GRADEpro software. Grading of Recommendations, Assessment, Development and Evaluations considerations will also be used to make an overall assessment of the quality of evidence.Ethics and disseminationThere is no requirement for ethics approval because no patient data will be collected at an individual level in this systematic review and meta-analysis.The results of this systematic review will be published in a peer-reviewed journal and presented at relevant conferences, any deviations from the protocol will be clearly documented and explained in its final report.PROSPERO registration numberCRD42020165110.

Abstract Introduction Cardiovascular disease (CVD) remains the leading cause of death in the world. Mobile phones have become ubiquitous in most developed societies. Smartphone applications, telemonitoring and clinician-driven short message service (SMS) allow for novel methods in managing chronic cardiovascular conditions such as ischaemic heart disease, heart failure and hypertension. Purpose To evaluate the impact of mobile phone-based interventions (MPIs) on mortality, hospitalisations and blood pressure and body mass index (BMI) in patients diagnosed with either acute coronary syndrome, heart failure or hypertension. Methods A systematic review was conducted using seven electronic databases, identifying all randomised control trials (RCTs) featuring an MPI in the management of these conditions. Meta-analysis was performed by using standard analytical techniques. The odds ratio (OR) was used as a summary statistic. Results Twenty-six RCTs including 6,713 patients were identified. Of these 26 studies, 13 examined text messaging intereventions, 10 studied telemonitoring interventions and three described smartphone applications with other functions. Twelve studies were included for meta-analysis. In patients with heart failure (n=1683), MPIs were associated with a significantly lower rate of all-cause hospital admissions at six months (31% vs. 36%, OR 0.77, 95% CI 0.62–0.97, p=0.03, I2 = 0). A significant difference was also demonstrated for heart-failure admissions (14.0% vs. 18.5%, OR 0.69, 95% CI 0.48 to 0.98, p=0.04, I2 = 26%). There was no difference in mortality (10.4% vs. 11.6% p=0.45). In patients with hypertension, the difference in systolic BP was 4.3mmHg less in the intervention group (95% CI: −7.8 to −0.78 mmHg, p=0.02). Four studies examined medication compliance as an endpoint in patients with ischaemic heart disease, and all four demonstrated a significant difference favouring the MPI group (see table 1). However, due to variable quantification of compliance, meta-analysis was not possible. There was no significant difference in the change in BMI from four studies after six or more months (mean difference −0.46, 95% CI: −1.44 to 0.52, P=0.36). Conclusions The available data suggests MPIs may have a role as valuable adjuncts in the management of chronic CVD.

Background. Depression is a debilitating comorbidity of heart failure (HF) that needs assessment and management. Along with mind-body exercise to deal with HF with depression, the use of TaiChi and/or Qigong practices (TQPs) has increased. Therefore, this systematic review assesses the effects of TQPs on depression among patients with HF. Methods. Randomized controlled trials (RCTs) that examined the effect of TQPs on depression in patients with HF were searched by five databases (PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, CINAHL, and China National Knowledge Infrastructure (CNKI)). With standardized mean difference (SMD) and 95% confidence intervals (95% CI), random-effects meta-analyses of the effect of TQPs on depressive symptoms were performed. Results. Of eight included RCTs, seven (481 patients) provided data for the meta-analysis. The pooling revealed that TQPs contribute to depression remission in HF (SMD −0.66; 95% CI −0.98 to −0.33, P < 0.0001 ; I2 = 64%). Its antidepressive effect was not influenced by intervention duration or exercise setting, but rather by ejection fraction subtype, depressive severity, and depression instruments. The beneficial effects were preserved when the study with the largest effect was removed. Conclusion. This study suggests that TQPs might be a good strategy for alleviating depressive symptoms in patients with HF. And rigorous-design RCTs, which focus on the identified research gaps, are needed to further establish the therapeutic effects of TQPs for depression in HF.

ABSTRACTObjectiveTo determine the impact of mesenchymal stromal cells outcomes important to patients with COVID-19.DesignThis is the protocol of a living systematic review.Data sourcesWe will conduct searches in PubMed/Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), grey literature and in a centralised repository in L·OVE (Living OVerview of Evidence). L·OVE is a platform that maps PICO questions to evidence from Epistemonikos database. In response to the COVID-19 emergency, L·OVE was adapted to expand the range of evidence it covers and customised to group all COVID-19 evidence in one place. The search will cover the period until the day before submission to a journal.Eligibility criteria for selecting studies and methodsWe adapted an already published common protocol for multiple parallel systematic reviews to the specificities of this question.We will include randomised trials evaluating the effect of mesenchymal stromal cells versus placebo or no treatment in patients with COVID-19. Randomised trials evaluating other coronavirus infections, such as MERS-CoV and SARS-CoV, and non-randomised studies in COVID-19 will be searched in case we find no direct evidence from randomised trials, or if the direct evidence provides low- or very low-certainty for critical outcomes.Two reviewers will independently screen each study for eligibility, extract data, and assess the risk of bias. We will pool the results using meta-analysis and will apply the GRADE system to assess the certainty of the evidence for each outcome.A living, web-based version of this review will be openly available during the COVID-19 pandemic. We will resubmit it every time the conclusions change or whenever there are substantial updates.Ethics and disseminationNo ethics approval is considered necessary. The results of this review will be widely disseminated via peer-reviewed publications, social networks and traditional media.PROSPERO RegistrationSubmitted to PROSPERO (awaiting ID allocation).
