ABSTRACT Pork is one of the major food sources of human salmonellosis worldwide, and beef products have been implicated in numerous foodborne outbreaks. Thus, effective interventions to reduce Salmonella contamination during beef and pork processing are of interest to both regulators and the meat industry. We conducted a rapid systematic review and meta-analysis of literature investigating the efficacy of slaughter and processing interventions to control Salmonella in beef and pork. Review steps included a comprehensive search strategy, relevance screening of abstracts, relevance confirmation of articles, data extraction, risk-of-bias assessment, meta-analysis (where appropriate), and a weight-of-evidence assessment. A total of 191 relevant experimental studies were identified. The results of two controlled trials indicated that hot water and steam treatments were effective for reducing the prevalence of Salmonella on beef carcasses (relative risk [RR] = 0.11; 95% confidence interval [CI]: 0.02, 0.58), whereas in four trials, prechill organic acid washes were effective for reducing Salmonella on pork carcasses (RR = 0.32; 95% CI: 0.13, 0.78), with high confidence in the estimates of effect. In four quasi-experimental studies, postexsanguination chemical washes were effective for reducing the prevalence of Salmonella on cattle hides, with low confidence in the specific estimate of effect; however, moderate confidence was found for the effect estimates of scalding (RR =0.20; 95% CI: 0.14, 0.29) and singeing (RR = 0.34; 95% CI: 0.22, 0.52) of pork carcasses. The overall evidence supports enhanced reductions of Salmonella through a multihurdle approach. Various slaughter and processing interventions can contribute to reduction of Salmonella on beef and pork carcasses, depending on the context of application, and an appropriate combination should be selected, validated, and verified by establishment operators under their local conditions.

ObjectiveThe use of herbal medicines for induction of labour (IOL) is common globally and yet its effects are not well understood. We assessed the efficacy and safety of herbal medicines for IOL.DesignSystematic review and meta-analysis of published literature.Data sourcesWe searched in MEDLINE, AMED and CINAHL in April 2017, updated in June 2018.Eligibility criteriaWe considered experimental and non-experimental studies that compared relevant pregnancy outcomes between users and non-user of herbal medicines for IOL.Data extraction and synthesisData were extracted by two reviewers using a standardised form. A random-effects model was used to synthesise effects sizes and heterogeneity was explored through I2statistic. The risk of bias was assessed using ‘John Hopkins Nursing School Critical Appraisal Tool’ and ‘Cochrane Risk of Bias Tool’.ResultsA total of 1421 papers were identified through the searches, but only 10 were retained after eligibility and risk of bias assessments. The users of herbal medicine for IOL were significantly more likely to give birth within 24 hours than non-users (Risk Ratio (RR) 4.48; 95% CI 1.75 to 11.44). No significant difference in the incidence of caesarean section (RR 1.19; 95% CI 0.76 to 1.86), assisted vaginal delivery (RR 0.73; 95% CI 0.47 to 1.14), haemorrhage (RR 0.84; 95% CI 0.44 to 1.60), meconium-stained liquor (RR 1.20; 95% CI 0.65 to 2.23) and admission to nursery (RR 1.08; 95% CI 0.49 to 2.38) was found between users and non-users of herbal medicines for IOL.ConclusionsThe findings suggest that herbal medicines for IOL are effective, but there is inconclusive evidence of safety due to lack of good quality data. Thus, the use of herbal medicines for IOL should be avoided until safety issues are clarified. More studies are recommended to establish the safety of herbal medicines.

Objective: Psychological well-being has been associated with desirable individual and organisational outcomes. This systematic review aims to assess the effectiveness of digital interventions for the improvement of psychological well-being and/or the prevention/management of poor mental well-being in the workplace. Methods: This review protocol is registered in PROSPERO (CRD42019142428). Scientific databases including MEDLINE, Web of Science, CINAHL, PsycINFO, Cochrane Register of Controlled Trials (CENTRAL) and EMBASE will be searched for relevant studies published between January 1990 and July 2019. Studies will be included if they report specific primary and secondary outcomes of digital interventions delivered to adults in the workplace for the improvement of their psychological wellbeing and/or the prevention/management of poor mental well-being and were published in English. Following screening of titles and abstracts, full texts of potentially eligible papers will be screened in duplicate to identify studies that assess the effectiveness of those digital interventions. Discrepancies will be resolved through consensus or by consulting a third reviewer. An integrated narrative synthesis will assess included studies’ findings, and a meta-analysis will be performed if included studies appear to be homogeneous. The “Cochrane Collaboration’s Risk of Bias” tool and the JBI (Joanna Briggs Institute) Critical Appraisal Checklist for Quasi-Experimental Studies will be used to appraise included studies. Conclusion: The results of this work will provide recommendations on the use of digital interventions for the promotion of psychological well-being at work. It will also guide the development of future workplace digital interventions and subsequent primary research in this field.

Objective: To review the latest literature on the effectiveness of DTIs in reducing loneliness in (older) adults. Data Sources: Electronic searches in PubMed, Medline, CINAHL, EMBASE and Web of Science covering publication period from 1 January 2010 to 31 July 2019. Subjects: Adult men and women Design: Systematic review and meta-analysis Main Outcome Measure: Loneliness. Study Selection: Primary studies that used DTIs for tackling loneliness in adults (aged ≥18 years) with follow-up measurements at least three months or more and publication in the English language. Data Extraction and Synthesis: Two researchers independently screened articles and extracted data on several variables: participants, interventions, comparators and outcomes. Data was extracted on the primary outcome i.e. loneliness measured at the baseline and follow-up measurements at three, four, six and twelve months after the intervention. Results: Six studies were selected from 4939 articles screened. Selected studies included 5 clinical trials (4 RCTs and 1 quasi experimental study) and one before and after study, which enrolled 646 participants (men =154 (24%), women =427 (66%), no gender information =65 (10%) with average age between 73 and 78 years (SD 6-11). Five clinical trials were included in the meta-analysis and standardised mean differences (SMD) were calculated for each trial and pooled across studies using a random effects model. The overall effect estimates were not statistically significant in follow-up measurements at three months (SMD= 0.02, 95% CI= -0.36, 0.40; P=0.92), four months (SMDs= -1.11, 95% CI= -2.60, 0.38; P=0.14) and six months (SMD= -0.11, 95% CI= -0.54, 0.32; P=0.61). The quality of evidence was very low to moderate in these trials. Conclusions: There is insufficient evidence to make conclusions that DTIs are effective in reducing loneliness in older adults. Future research may consider RCTs with larger sample sizes and longer duration of interventions and follow-up.

ObjectivesImproved biomass cookstoves may help reduce the substantial global burden of morbidity and mortality due to household air pollution (HAP) that disproportionately affects women and children in low and middle income countries (LMICs).DesignSystematic review and meta-analysis of (quasi-)experimental studies identified from 13 electronic databases (last update: 6 April 2018), reference and citation searches and via expert consultation.SettingLMICsParticipantsWomen and childrenInterventionsImproved biomass cookstovesMain outcome measuresLow birth weight (LBW), preterm birth, perinatal mortality, paediatric acute respiratory infections (ARIs) and COPD among women.ResultsWe identified 53 eligible studies, including 24 that met prespecified design criteria. Improved cookstoves had no demonstrable impact on paediatric lower ARIs (three studies; 11 560 children; incidence rate ratio (IRR)=1.02 (95% CI 0.84 to 1.24)), severe pneumonia (two studies; 11 061 children; IRR=0.88 (95% CI 0.39 to 2.01)), LBW (one study; 174 babies; OR=0.74 (95% CI 0.33 to 1.66)) or miscarriages, stillbirths and infant mortality (one study; 1176 babies; risk ratio (RR) change=15% (95% CI –13 to 43)). No (quasi-)experimental studies assessed preterm birth or COPD. In observational studies, improved cookstoves were associated with a significant reduction in COPD among women: two studies, 9757 participants; RR=0.74 (95% CI 0.61 to 0.90). Reductions in cough (four studies, 1779 participants; RR=0.72 (95% CI 0.60 to 0.87)), phlegm (four studies, 1779 participants; RR=0.65 (95% CI 0.52 to 0.80)), wheezing/breathing difficulty (four studies; 1779 participants; RR=0.41 (95% CI 0.29 to 0.59)) and conjunctivitis (three studies, 892 participants; RR=0.58 (95% CI 0.43 to 0.78)) were observed among women.ConclusionImproved cookstoves provide respiratory and ocular symptom reduction and may reduce COPD risk among women, but had no demonstrable child health impact.RegistrationPROSPERO: CRD42016033075

The objective of this review is to evaluate the effectiveness of digital health supported targeted patient communication versus usual provision of health information, on the recovery of fragility fractures. The review considered studies including older people, aged 50 and above, with a fragility fracture. The primary outcome was prevention of secondary fractures by diagnosis and treatment of osteoporosis, and its adherence. This review considered both experimental and quasi-experimental study designs. A comprehensive search strategy was built to identify key terms including Medical subject headings (MeSH) and applied to the multiple electronic databases. An intention to treat analysis was applied to those studies included in the meta-analysis and odds ratio was calculated with random effects. Altogether, 15 studies were considered in the final stage for this systematic review. Out of these, 10 studies were Randomised controlled trials (RCT) and five were quasi experimental studies, published between the years 2003 and 2016 with a total of 5037 participants. Five Randomised control trails were included in the meta-analysis suggesting that digital health supported interventions were overall, twice as effective when compared with the usual standard care (OR 2.13, 95% CI 1.30–3.48), despite the population sample not being homogeneous. Findings from the remaining studies were narratively interpreted.

Purpose: To examine the effects on anxiety of mindfulness-based interventions (MBIs) among youth with anxiety disorders. Method: Systematic review and meta-analytic procedures were employed to synthesize experimental and quasi-experimental studies authored between 1980 and 2015. Results: The search yielded five studies from five countries reporting results for a total of 188 youth between the ages of 5 and 18 (mean age 13.26) who met criteria for an anxiety disorder. Risk of bias varied across studies. Meta-analytic results suggest a moderate and significant effect ( g = .62; 95% confidence interval = [0.20, 1.04], p = .004). Heterogeneity was moderate ( I2 = 47.22) and not statistically significant ( Q = 7.58, df = 4, p = .11), thus moderator analyses were not warranted. Discussion: The findings of this review suggest that MBIs for the treatment of anxiety in youth with anxiety disorders are effective.

IntroductionThe 2016 WHO antenatal guidelines propose evidence-based recommendations to improve maternal outcomes. We aim to complement these recommendations by describing and estimating the effects of the interventions recommended by WHO on maternal well-being or functioning.Methods and analysisWe will conduct a systematic review of experimental and quasi-experimental studies evaluating women’s well-being or functioning following the implementation of evidence-based antenatal interventions, published in peer-reviewed journals through a 15-year interval (2005–2020). The lead reviewer will screen all records identified at MEDLINE, EMBASE, CINAHL Plus, LILACS and SciELO. Two other reviewers will control screening strategy quality. Quality and risk of bias will be assessed using a specially designed instrument. Data synthesis will consider the instruments applied, how often they were used, conditions/interventions for positive or negative effects documented, statistical measures used to document effectiveness and how results were presented. A random-effects meta-analysis comparing frequently used instruments may be conducted.Ethics and disseminationThe study will be a systematic review with no human beings’ involvement, therefore not requiring ethical approval. Findings will be disseminated through peer-reviewed publication and scientific events.PROSPERO registration numberCRD42019143436.

ABSTRACT Objectives: The aim of this systematic review was to examine the effectiveness of pre-anaesthetic assessment clinics (PACs) implemented to improve quality and patient safety in perioperative care. Design: Systematic review. Data sources: The electronic databases CINAHL Plus with Full Text (EBSCOhost), Medline, and Embase (OvidSP) were systematically searched from 1st April, 1996 to 4th February, 2021. Eligibility criteria: The main inclusion criterion was that the study, using empirical quantitative methods, addressed the effectiveness of PACs. Data extraction and synthesis: Titles, abstracts, and full texts were screened in duplicate by two authors. Risk of bias assessment, using the Joanna Briggs Institute critical appraisal checklist for quasi-experimental studies, and data extraction were performed by one author and checked by the other author. Results were synthesised narratively owing to the heterogeneity of the included studies. Results: Seven prospective controlled studies were conducted. Most studies had a high risk of bias. Three studies reported a significant reduction in the length of the hospital stay, and two studies reported a significant reduction in cancellation of surgery for medical reasons when patients were seen in the PAC. In addition, the included studies presented mixed results regarding anxiety in patients. Conclusion: This systematic review demonstrated a reduction in the length of hospital stay and cancellation of surgery when the patients had been assessed in the PAC. There is a need for high-quality prospective studies to gain a deeper understanding of the effectiveness of PACs. PROSPERO registration number: CRD42019137724

Background: There is a lack of systematic review exploring the effectiveness of Enhanced Recovery After Surgery (ERAS) in hysterectomy in promoting better recovery. Objectives: To synthesize the best available evidence of the effectiveness of ERAS intervention in promoting better recovery of shortened length of hospital stay (primary outcome), lower readmission, and complication rates (secondary outcomes) among patients undergoing hysterectomy due to benign conditions as compared to conventional perioperative care. Search Strategy: Seven electronic databases were searched from the date of inception to December 2020. Selection Criteria: Randomized controlled trials, cohort studies, or quasi-experimental studies published in English examining the effects of ERAS for women diagnosed with benign gynecologic diseases and underwent either abdominal or laparoscopic hysterectomy were included. Data Collection and Analysis: Two reviewers independently conducted database search, data extraction, and methodological quality assessment. Meta-analyses were performed for all outcomes. The overall quality of evidence was assessed using GRADE. Main Results: Nine studies were included in this review. Meta-analysis showed a statistically significant reduction in length of hospital stay (SMD = -0.76, 95% CI [-1.06, -0.46], Z = 4.72, p < .00001), readmission rate (RR = 0.65, 95% CI [0.44-0.96]; Z = 2.16, p = .03) and complication rate (RR = 0.61, 95% CI [0.48-0.77]; Z = 4.17, p < .0001), with high certainty of evidence. Conclusions: The effectiveness of ERAS in improving recovery indicates that hospitals could adopt the protocol to improve patients’ health and wellbeing. Future studies can focus more on standardizing the protocol’s elements.
