Translational medical research and liver transplantation: systematic review.

ABSTRACT: Translational medicine has become a priority, but there is still a big difference between the arrival of new treatments and investment. Basic science should not be neglected because the translation from basic research is not sustained in the absence of basic research. The purpose of this literature review was to analyze the translational medicine in the liver transplant field: liver ischemia-reperfusion injury (IRI), immunosuppression, clinical and surgical complications, small-for-size syndrome (SFSS), rejection, and ongoing innovations (liver machine, liver preservation, artificial livers, and regenerative medicine). We performed a systematic literature review that were updated in October 2016. The searches were performed in the Cochrane Central Register of Controlled Trials and Review, PubMed/Medline, Embase, and LILACS databases. All the selected studies on the management of translational medical research in liver transplantation (LT) were analyzed. Initially the search found 773 articles. Methodological viewing and analysis of the articles, followed by the application of scientific models, including translational medicine in the liver transplant field. In conclusions, this review demonstrates the application of scientific research with translation medical benefits regarding the LT. The literature has a great tendency, improvements and investments in the study of translational medicine in LT. Innovative studies and technologies from basic science help to clarify clinical doubts. Moreover, evidence increases the importance of scientific research in quality of clinical practice care.

Project description:PhenomenonResearch literacy remains important for equipping clinicians with the analytical skills to tackle an ever-evolving medical landscape and maintain an evidence-based approach when treating patients. While the role of research in medical education has been justified and established, the nuances involving modes of instruction and relevant outcomes for students have yet to be analyzed. Institutions acknowledge an increasing need to dedicate time and resources towards educating medical undergraduates on research but have individually implemented different pedagogies over differing lengths of time.ApproachWhile individual studies have evaluated the efficacy of these curricula, the evaluations of educational methods and curriculum design have not been reviewed systematically. This study thereby aims to perform a systematic review of studies incorporating research into the undergraduate medical curriculum, to provide insights on various pedagogies utilized to educate medical students on research.FindingsStudies predominantly described two major components of research curricula-(1) imparting basic research skills and the (2) longitudinal application of research skills. Studies were assessed according to the 4-level Kirkpatrick model for evaluation. Programs that spanned minimally an academic year had the greatest proportion of level 3 outcomes (50%). One study observed a level 4 outcome by assessing the post-intervention effects on participants. Studies primarily highlighted a shortage of time (53%), resulting in inadequate coverage of content.InsightsThis study highlighted the value in long-term programs that support students in acquiring research skills, by providing appropriate mentors, resources, and guidance to facilitate their learning. The Dreyfus model of skill acquisition underscored the importance of tailoring educational interventions to allow students with varying experience to develop their skills. There is still room for further investigation of multiple factors such as duration of intervention, student voluntariness, and participants' prior research experience. Nevertheless, it stands that mentoring is a crucial aspect of curricula that has allowed studies to achieve level 3 Kirkpatrick outcomes and engender enduring changes in students.Supplementary informationThe online version contains supplementary material available at 10.1007/s40670-020-01183-w.

Project description:BackgroundChronic kidney disease following liver transplantation is a major long-term complication. Most liver transplant recipients with kidney failure will be treated with dialysis instead of kidney transplantation due to noneligibility and shortage in organ availability. In this population, the role of peritoneal dialysis (PD) as a modality of kidney replacement therapy (KRT) remains unclear.ObjectiveTo determine the feasibility regarding safety, technique survival, and dialysis efficiency of PD in liver transplant recipients requiring KRT for maintenance dialysis.DesignSystematic review.SettingInterventional and observational studies reporting the use of PD after liver transplantation.PatientsAdult liver transplant recipients with kidney failure treated with maintenance KRT.MeasurementsExtracted data included eligibility criteria, study design, demographics, and PD modality. The following outcomes of interest were extracted: rate of peritonitis and microorganisms involved, noninfectious peritoneal complications, technique survival, and kidney transplantation-censored technique survival. Non-PD complications included overall survival, liver graft dysfunction, and hospitalization rate.MethodsThe following databases were searched until July 2020: MedLine/PubMed, EMBASE, CINAHL, and Cochrane Library. Two reviewers independently screening all titles and abstracts of all identified articles. Due to the limited sample size, observational designs and study heterogeneity expected, no meta-analysis was pre-planned. Descriptive statistics were used to report all results.ResultsFrom the 5263 identified studies, 4 were included in the analysis as they reported at least 1 outcome of interest on a total of 21 liver transplant recipients, with an overall follow-up duration on PD of 19.0 (Interquartile range [IQR]: 9.5-29.5) months. Fifteen episodes of peritonitis occurred in a total cumulative PD follow-up of 514 patient-months, representing an incidence rate of 0.35 per year. These episodes did not result in PD technique failure, mortality, or impairment of liver graft function.LimitationsLimitations include the paucity of studies in the field and the small number of patients included in each report, a risk of publication bias and the impossibility to directly compare hemodialysis to PD in this population. These results, therefore, must be interpreted with caution.ConclusionsBased on limited data reporting the feasibility of PD in liver transplant recipients with kidney failure, no signal was associated with an increased risk of infectious complications. Long-term studies evaluating this modality need to be performed.Registration prosperoCRD42020218374.

Project description:BACKGROUND:Crowdsourcing is used increasingly in health and medical research. Crowdsourcing is the process of aggregating crowd wisdom to solve a problem. The purpose of this systematic review is to summarize quantitative evidence on crowdsourcing to improve health. METHODS:We followed Cochrane systematic review guidance and systematically searched seven databases up to September 4th 2019. Studies were included if they reported on crowdsourcing and related to health or medicine. Studies were excluded if recruitment was the only use of crowdsourcing. We determined the level of evidence associated with review findings using the GRADE approach. RESULTS:We screened 3508 citations, accessed 362 articles, and included 188 studies. Ninety-six studies examined effectiveness, 127 examined feasibility, and 37 examined cost. The most common purposes were to evaluate surgical skills (17 studies), to create sexual health messages (seven studies), and to provide layperson cardio-pulmonary resuscitation (CPR) out-of-hospital (six studies). Seventeen observational studies used crowdsourcing to evaluate surgical skills, finding that crowdsourcing evaluation was as effective as expert evaluation (low quality). Four studies used a challenge contest to solicit human immunodeficiency virus (HIV) testing promotion materials and increase HIV testing rates (moderate quality), and two of the four studies found this approach saved money. Three studies suggested that an interactive technology system increased rates of layperson initiated CPR out-of-hospital (moderate quality). However, studies analyzing crowdsourcing to evaluate surgical skills and layperson-initiated CPR were only from high-income countries. Five studies examined crowdsourcing to inform artificial intelligence projects, most often related to annotation of medical data. Crowdsourcing was evaluated using different outcomes, limiting the extent to which studies could be pooled. CONCLUSIONS:Crowdsourcing has been used to improve health in many settings. Although crowdsourcing is effective at improving behavioral outcomes, more research is needed to understand effects on clinical outcomes and costs. More research is needed on crowdsourcing as a tool to develop artificial intelligence systems in medicine. TRIAL REGISTRATION:PROSPERO: CRD42017052835. December 27, 2016.
