Prevalence of infection in kidney transplantation from living versus deceased donor: systematic review and meta-analysis

OBJECTIVE To verify if the type of donor is a risk factor for infection in kidney transplant recipients. METHODS Systematic Review of Literature with Meta-analysis with searches conducted in the databases MEDLINE, LILACS, Embase, Cochrane, Web of Science, SciELO and CINAHL. RESULTS We selected 198 studies and included four observational studies describing infections among patients distinguishing the type of donor. Through meta-analysis, it was shown that in patients undergoing deceased donor transplant, the outcome infection was 2.65 higher, than those who received an organ from a living donor. CONCLUSION The study showed that deceased kidney donor recipients are at an increased risk for developing infections and so the need for establishing and enforcing protocols from proper management of ischemic time to the prevention and control of infection in this population emerges.

Genetic polymorphisms in the Cytochrome P450 family and squamous cell carcinoma of the oral cavity, pharynx and larynx

Objective:To analyze the genetic polymorphisms of the cytochrome P450 family and their relationship with squamous cell carcinoma of the oral cavity, pharynx and larynx.Methods: We present a narrative literature review, conducted in Pubmed, Lilacs and Cochrane Databases of articles published in the last five years correlating genetic polymorphisms of the cytochrome P450 family and cancer risk in different populations worldwide.Results: We initially found 65 articles and, after selection criteria, 20 case-control studies with various populations worldwide were eligible. The most studied polymorphisms were those of CYP2E1 and CYP1A1 subfamilies. There is little about the other subfamilies. The association found between polymorphisms and cancer risk amounted to a countless number of variables, amongst them: population, selection methods, racial factors and different modes of exposure to carcinogens, genotyping methods, and nomenclature of the polymorphisms.Conclusion: so far, there is no proven link between genetic polymorphisms of cytochrome P450 family and squamous cell carcinoma of the oral cavity, pharynx and larynx relationship.

Tai Chi Chuan for Cardiac Rehabilitation in Patients with Coronary Arterial Disease

Background:Several studies have shown that Tai Chi Chuan can improve cardiac function in patients with heart disease.Objective:To conduct a systematic review of the literature to assess the effects of Tai Chi Chuan on cardiac rehabilitation for patients with coronary artery disease.Methods:We performed a search for studies published in English, Portuguese and Spanish in the following databases: MEDLINE, EMBASE, LILACS and Cochrane Register of Controlled Trials. Data were extracted in a standardized manner by three independent investigators, who were responsible for assessing the methodological quality of the manuscripts.Results:The initial search found 201 studies that, after review of titles and abstracts, resulted in a selection of 12 manuscripts. They were fully analyzed and of these, nine were excluded. As a final result, three randomized controlled trials remained. The studies analyzed in this systematic review included patients with a confirmed diagnosis of coronary artery disease, all were clinically stable and able to exercise. The three experiments had a control group that practiced structured exercise training or received counseling for exercise. Follow-up ranged from 2 to 12 months.Conclusion:Preliminary evidence suggests that Tai Chi Chuan can be an unconventional form of cardiac rehabilitation, being an adjunctive therapy in the treatment of patients with stable coronary artery disease. However, the methodological quality of the included articles and the small sample sizes clearly indicate that new randomized controlled trials are needed in this regard.

Revisão sistemática da acurácia dos testes diagnósticos: uma revisão narrativa

Este artigo tem o objetivo de realizar uma revisão narrativa sobre revisão sistemática da acurácia dos testes diagnósticos. Foi realizada busca na Cochrane Methodology Reviews (Cochrane Reviews of Diagnostic Test Accuracy), Medline e LILACS, bem como busca manual das listas de referências dos artigos incluídos na revisão. As estratégias de busca empregadas foram as seguintes, empregando-se títulos de assuntos e termos livres: 1. na Cochrane Methodology Reviews: accuracy study "Methodology" 2. Na Pubmed "Meta-Analysis "[Publication Type] AND "Evidence-Based Medicine"[Mesh]) AND "Sensitivity and Specificity"[Mesh]; 3. Na LILACS: (revisao sistematica) or "literatura de REVISAO como assunto" [Descritor de assunto] and (sistematica) or "SISTEMATICA" [Descritor de assunto] and (acuracia) or "SENSIBILIDADE e especificidade" [Descritor de assunto]. Em suma, a preparação e o planejamento metodológicos das revisões sistemáticas de testes diagnósticos é ulterior àqueles empregados nas revisões sistemáticas das intervenções terapêuticas. Há muitas fontes de heterogeneidade nos desenhos dos estudos de teste diagnóstico, o que dificulta muito a síntese - metanálise - dos seus resultados. Para contornar esse problema, existem atualmente normas, exigidas pelas principais revistas biomédicas, para a submissão de um manuscrito sobre testes diagnósticos.
