Upper gastrointestinal (UGI) cancers are among the most common cancers in the world, four of them being among the top eight causes of cancer related mortality. Included among UGI cancers are oesophageal, gastric, liver, biliary, pancreatic and small intestinal cancers. Despite more than half a century of well designed…

BACKGROUND: GRADE (Grading of Recommendations, Assessment, Development and Evaluation) is a widely used approach in the fields of medicine and public health to assess the outcome-specific certainty of the evidence in systematic reviews. OBJECTIVES: To make the GRADE approach comprehensible in order to facilitate…

PURPOSE OF REVIEW: Evidence-based women's healthcare is underpinned by systematic reviews and guidelines. Generating an evidence synthesis to support guidance for clinical practice is a time-consuming and labour-intensive activity that delays transfer of research into practice. Artificial intelligence has the potential…

RESEARCH DESIGN AND METHODS: A systematic review of reviews was designed, registered with PROSPERO, and then conducted. This focused on systematic reviews of research…

BACKGROUND: The aim of the present study was to determine empirically which electronic databases contribute best to a literature search in surgical systematic reviews. METHODS: For ten published systematic reviews, the systematic literature searches were repeated in the databases MEDLINE, Web of Science, CENTRAL, and…

AIM: To validate a framework of factors that influence the relationship of transformational leadership and safety climate, and to enable testing of safety chain factors by generating hypotheses regarding their mediating and moderating effects. BACKGROUND: Understanding the patient safety chain and mechanisms by which…

In our hospital, we are currently working to manage the appropriateness of vitamin B₁₂ (B12) testing. Unfortunately, the classic evidence-based approach is unhelpful in this process and meta-analyzing data on the accuracy of this marker for cobalamin deficiency detection is misleading due to the lack of r…

The worldwide prevalence of food allergy appears to be increasing. Early life environmental factors are implicated in the aetiology of this global epidemic. The largest burden of disease is in early childhood, where research efforts aimed at prevention have been focused. Evidence synthesis from good quality systematic…

Ideally, healthcare systematic reviews (SRs) should be beneficial to practicing professionals in making evidence-based clinical decisions. However, the conclusions drawn from SRs are directly related to the quality of the SR and of the included studies. The aim was to investigate the methodological quality and key desc…

Wound management experienced significant changes in the last half century, while acknowledging the concept of "moist wound healing" and the strategy of "wound bed preparation". New solutions in this area have brought by developing new methods of debridement, exudates management and decrease of bacterial load. Debrideme…

Systematic reviews (SRs) are published with an increasing rate in many fields of biomedical literature, including orthodontics. Although SRs should consolidate the evidence-based characteristics of contemporary orthodontic practice, doubts on the validity of their conclusions have been frequently expressed. The aim of…

Strengthening health systems is a key challenge to improving the delivery of cost-effective interventions in primary health care and achieving the vision of the Alma-Ata Declaration. Effective governance, financial and delivery arrangements within health systems, and effective implementation strategies are needed urgen…

Echogenic intracardiac focus and choroid plexus cysts are common findings at the midtrimester ultrasound. These findings have been linked with an increased risk of Down syndrome and trisomy 18. Most fetuses with these findings will, however, not have chromosomal abnormalities, especially when these findings are isolate…

Set out the basic problems of classification, diagnostics and differential diagnostics of chronic gastritis and functional dyspepsia in the context of the Kyoto global consensus.

BACKGROUND: Oral leukoplakia (OL) represents the most common oral potentially malignant disorder globally, with highly variable reported malignant transformation (MT) rates creating challenges for evidence-based clinical management. OBJECTIVE: To systematically synthesize evidence on MT prevalence in OL and evaluate p…

DESIGN: Umbrella review. DATA SOURCES: Medline, Embase, Lilacs, Cochrane Database of Systematic Reviews for peer-reviewed literature, PROSPE…

This meta-review provides the first meta-analytic evidence from published meta-analyses examining the effectiveness of acute exercise interventions on cognitive function. A multilevel meta-analysis with a random-effects model and tests of moderators were performed in R. Thirty systematic reviews with meta-analyses (383…

INTRODUCTION: The aim of this study was to establish an international consensus statement on the indications for the addition of a patellofemoral joint arthroplasty (PFJA) in patients with a unicondylar knee arthroplasty (UKA) and symptomatic progression of patellofemoral compartment osteoarthritis. MATERIALS AND METH…

OBJECTIVES: The purpose of this study was to identify, critically assess, and summarize evidence of the effectiveness of primary care treatments for adults with non-specific chronic low back pain (NSCLBP).
