AIM: To evaluate published trials examining oral post-operative protein supplementation in patients having undergone gastrointestinal surgery and assessment of reported results.METHODS: Database searches (MEDLINE, BIOSIS, EMBASE, Cochrane Trials, Cinahl, and CAB), searches of reference lists of relevant papers, and expert referral were used to identify prospective randomized controlled clinical trials. The following terms were used to locate articles: “oral’’ or “enteral’’ and “postoperative care’’ or “post-surgical’’ and “proteins’’ or “milk proteins’’ or “dietary proteins’’ or “dietary supplements’’ or “nutritional supplements’’. In databases that allowed added limitations, results were limited to clinical trials that studied humans, and publications between 1990 and 2014. Quality of collated studies was evaluated using a qualitative assessment tool and the collective results interpreted.RESULTS: Searches identified 629 papers of which, following review, 7 were deemed eligible for qualitative evaluation. Protein supplementation does not appear to affect mortality but does reduce weight loss, and improve nutritional status. Reduction in grip strength deterioration was observed in a majority of studies, and approximately half of the studies described reduced complication rates. No changes in duration of hospital stay or plasma protein levels were reported. There is evidence to suggest that protein supplementation should be routinely provided post-operatively to this population. However, despite comprehensive searches, clinical trials that varied only the amount of protein provided via oral nutritional supplements (discrete from other nutritional components) were not found. At present, there is some evidence to support routinely prescribed oral nutritional supplements that contain protein for gastrointestinal surgery patients in the immediate post-operative stage.CONCLUSION: The optimal level of protein supplementation required to maximise recovery in gastrointestinal surgery patients is effectively unknown, and may warrant further study. 相似文献

BackgroundTrial registration can provide more reliable study designs, however, the final publications are not exempt from bias. This study aimed to show the characteristics of foot & ankle surgery-related clinical trials registered in ClinicalTrials.gov (CTG) and analyze possible risk factors that can lead to discrepancies between the original trial registry and published results.MethodsFoot & ankle surgery-related randomized controlled studies registered in CTG with an anticipated completion date until 2018 were extracted. 157 trials were found eligible for final analysis and corresponding publications were investigated through literature databases. Discrepancies between trial registries and published results were analyzed.Results67.5% of trials were registered whether during the trial period or after completion. 46.5% were funded by industry. 54.8% of trials were reported to be completed. The results of 66 (42%) trials were published in a journal. There was a sample size discrepancy in 57.6%, follow-up time discrepancy in 28.8%, primary outcome discrepancy in 45.5%, and inclusion/exclusion criteria discrepancy in 89.4% of registries. Sample size, inclusion/exclusion criteria discrepancies were significantly more in trials funded by industry (p = 0.024, 0.001, 0.037, respectively). Industry-funded studies reported positive results more frequently (p = 0.011).ConclusionOnly 42% of all registered foot & ankle surgery-related studies had the chance to be published. The majority of studies presented discrepancies in sample size, outcome assessment method, follow-up time, or inclusion/exclusion criteria. Industry-funded studies showed a higher rate of discrepancies and were more inclined towards reporting positive results indicating a risk of bias in assessments.Level of clinical evidenceLevel 3. 相似文献

BackgroundIn 2009, the Burns Registry of Australia and New Zealand (BRANZ) published a set of clinical quality indicators (QIs) to monitor performance, improve quality of care, and inform and change policy. With several years of data collected since the initial development of the indicators for burns, the BRANZ QI Working Party reviewed the clinical QIs for relevance and meaning, and considered new QIs that had not been collected previously.MethodUsing published literature and expert opinion, the QI Working Party, consisting of multidisciplinary burn clinicians, reviewed the QIs for burn care to be included as routine data items in the BRANZ.ResultsIn July 2016, the list of clinical QIs in the BRANZ was updated to 23 QIs/data items, covering structure, process, and outcome measures. Four QIs were removed as they were not found to be useful, nine QIs/data items were revised, and eight new QIs/data items were added as they were considered to be clinically useful.ConclusionThis review outlines the changes made to the QIs collected by the BRANZ four years since their development and implementation. Ongoing refinement of the BRANZ QIs will ensure that high quality data is collected to drive improvements in clinical and patient outcomes. 相似文献

The present study aims to identify (1) what proportion of abstracts of clinical trials presented at The American Society for Laser Medicine and Surgery (ASLMS) annual meetings are published as full reports, (2) time to publication, and (3) factors that may predict the publication of research in peer-reviewed journals. Two investigators independently hand-searched all abstracts of the ASLMS meetings to identify all reports of clinical trials. Details of sample size, the country of origin, topic of research, type of presentation, type of laser, direction of outcome, and statistical significance were recorded for each abstract. To determine the full publication status of each study, The Cochrane Central Register of Controlled Trials, PubMed, and EMBASE was searched. A total of 198 abstracts were identified. Of these, 87 abstracts (44%) have been fully published. The average time from presentation at the meeting to full publication was 57 months (95% confidence interval = 52-61), and the estimated rate of abstracts published at 1, 2, and 4 years was 15, 30, and 38%, respectively. There is significant tendency for being fully published in high-power laser studies, with USA as country of origin, and orally presented. Our findings supports this opinion that conference abstracts can be an important source for systematic reviews and failure to identify trials presented in congresses might threaten the validity of systematic reviews. 相似文献

ObjectivesPatient-reported outcomes (PRO) help patients, caretakers, clinicians, and policy makers make informed decisions regarding treatment effectiveness. Our objective was to assess the quality of PRO reporting and methodological strengths and weaknesses in randomized controlled trials (RCT) in bladder cancer.MethodsA systematic literature search of bladder cancer RCT published between January 2004 and March 2014 was performed. Relevant studies were evaluated using a predetermined extraction form that included trial demographics, clinical and PRO characteristics, and standards of PRO reporting based on recommendations of the International Society for Quality of Life Research.ResultsIn total, 9 RCTs enrolling 1,237 patients were evaluated. All studies were in patients with nonmetastatic disease. In 5 RCTs, a PRO was the primary end point. Most RCTs did not report the mode of administration of the PRO instrument or the methods of collecting data. No RCT addressed the statistical approaches for missing data.ConclusionsWe found that few RCTs in bladder cancer report PRO as an outcome. Efforts to expand PRO reporting to more RCTs and improve the quality of PRO reporting according to recognized standards are necessary for facilitating clinical decision making. 相似文献

Objective
To evaluate the methodological quality of published randomised controlled trials (RCTs) in burn care treatment and management.Methods
Using a predetermined search strategy we searched Ovid MEDLINE (1950 to January 2008) database to identify all English RCTs related to burn care. Full text studies identified were reviewed for key demographic and methodological characteristics. Methodological trial quality was assessed using the Jadad scale.Results
A total of 257 studies involving 14,535 patients met the inclusion criteria. The median Jadad score was 2 (out of a best possible score of 5). Information was given in the introduction and discussion sections of most RCTs, although insufficient detail was provided on randomisation, allocation concealment, and blinding. The number of RCTs increased between 1950 and 2008 (Spearman's rho = 0.6129, P < 0.001), although the reporting quality did not improve over the same time period (P = 0.1896) and was better in RCTs with larger sample sizes (median Jadad score, 4 vs. 2 points, P < 0.0001). Methodological quality did not correlate with journal impact factor (P = 0.2371).Conclusions
The reporting standards of RCTs are highly variable and less than optimal in most cases. The advent of evidence-based medicine heralds a new approach to burns care and systematic steps are needed to improve the quality of RCTs in this field. Identifying and reviewing the existing number of RCTs not only highlights the need for burn clinicians to conduct more trials, but may also encourage burn health clinicians to consider the importance of conducting trials that follow appropriate, evidence-based standards. 相似文献9.

ObjectivesChild and adolescent burn survivors benefit from skills to cope with the physical and mental challenges associated with their injuries. Burn camps can offer an opportunity to build these skills. In this study, we systematically review the best available evidence on burn camps in order to better assess their impact on burn survivors.MethodA systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. A total of 815 articles on recreational therapeutic camps for burn survivors were retrieved from PubMed, PsycINFO, CINAHL and Scopus restricted to the English language and published before or by May 2018. Critical Appraisal Skills Programme (CASP) for Qualitative Studies Checklist and the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for non-randomized experimental studies were used to assess the methodological rigour of the quantitative studies.ResultsQuantitative data did not support any long-lasting impacts on psychosocial wellbeing. Qualitative data showed children, parents and staff all perceived benefits from camp attendance, including companionship and belonging.ConclusionFurther research is required to understand the lack on congruence between qualitative and quantitative data. Qualitative data suggests burn camps are beneficial for children with burn injuries. 相似文献

Background
Pediatric surgical randomized clinical trials (RCTs) are labor-intensive and costly. This systematic review investigated patient accrual and estimates of study duration in RCTs by interrogating enrollment and registration practices.Methods
We performed a peer-review search of multiple databases from 2000 to 2016 evaluating RCTs salient to the field with inclusion mandated that a self-identified pediatric surgeon be listed as an author. Trial registries were also searched. RCTs were appraised, and predictors of success were evaluated using multivariate logistic regression, with success defined as achievement of recruitment objectives.Results
After screening, 137 RCTs were analyzed. Mean Jadad score was 1.80 (median = 2). CONSORT scores ranged between 17% and 97% (median = 58%). Sixty-seven studies described sample-size determination, 49 reported projected enrollment, and 26 were successful. Among 26 registered RCTs, 15 disclosed their expected completion date, which was achieved by 8. On average, protocols underwent 3.42 iterations. 9% of trials were terminated before completion, most commonly owing to poor recruitment. Trial registration and urgent cases significantly predicted success on multivariable analysis (p < 0.05).Conclusion
Overall quality of reporting in pediatric surgical trials is poor. Sample-size calculation and patient accrual are frequently poorly performed or underestimated, resulting in trial overrun and/or premature termination. These data may help inform subsequent study design and facilitate successful completion.Level of Evidence

The aim of the study was to conduct a systematic review to identify and appraise the evidence on possible association of the site of venous catheter insertion in burn patients and an increased occurrence of catheter-related infection. Searches were performed in MEDLINE, LILACS, CINAHL, EMBASE, Web of Science and The Cochrane Library. Nine studies were selected for the review; four of them mentioned, directly or indirectly, an association between catheter-related infection and the insertion of the catheter either in the burn wound or in surrounding area, and five studies investigated the occurrence of infection related to both the catheter and the anatomical sites of catheter insertion. Higher infection rates occurred when the catheters were inserted directly in the burn wound or near the wound (level of evidence IV) or in the femoral vein (level of evidence IV). No significant differences in infection occurrence rates were observed between central catheters and peripherally inserted central catheter (level of evidence IV). Further investigations for techniques and types of coverage of venous catheter insertion dressings are important for preventing infection in burn patients. Also, new technologies for venous access must be evaluated. 相似文献

IntroductionA burn is a trauma that breaks the skin barrier, causing local and systemic responses. Treatment is complex, multiprofessional and expensive. In addition to surgical treatment, topical dressings can be used to keep the wound moist, reduce the risk of infection and stimulate healing. Clinical studies show that topical use of fibroblast growth factors may accelerate healing. An assessment of the quality of the available evidence and its strength of recommendation is necessary.ObjectiveThis study aimed to evaluate the effectiveness and safety of topical use of fibroblast growth factor, compared to other topical treatments or placebo, in the healing of burns, to determine the strength of recommendation.MethodBased on a defined search strategy, randomized and quasi-randomized clinical trials, available in electronic databases, were gathered. These compare the topical use of FGF versus other topical or non-treatment. The primary outcome was healing and as adverse effects: pain, infection and mortality. The systematic review protocol was registered on the PROSPERO platform (CRD42018089556), developed in accordance with the “Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) 2015” and within the “SWiM guideline 2019”. GRADEpro was used for the critical analysis of the methodology of the studies.ResultsFour clinical trials were found, in which FGF reduced the healing time and improved the appearance of the scar. Two trials were determined to be of low strength, while two others have a moderate recommendation strength.ConclusionThis review gathered available evidence, between low and moderate recommendation strength for the use of FGF as a topical dressing. Further rigorous trials are needed to improve the strength of recommendation for topical use of FGF for burns. 相似文献

Chemical burns can cause deep injury and subsequently significant scarring to the skin. The mechanism and pathophysiology of chemical burns is distinct to thermal burns, and recommended first aid approaches are consequently different. Twenty minutes of cool running water is an effective first aid measure to improve outcomes after thermal burn. For chemical burns to the skin, the recommendations are immediate water lavage for 60 min, removal of contaminated clothing if not stuck to the skin and then covering the wound with a sterile dressing. This review assesses the peer-reviewed literature to find the evidence behind the efficacy of cutaneous chemical burn first aid on short term outcomes such as length of hospital stay, depth of burn and longer-term outcomes such as scarring; in particular, the effect of immediate or early water lavage, and the effect of the duration of water lavage. Ocular chemical burns were not included in this review. The review suggests some evidence to support that the early application of cool water irrigation may reduce length of hospital stay and the extent of scarring. Community education should emphasize that water irrigation is recommended and that the earlier this happens, the better. 相似文献
