Cluster-Randomized Studies.
2018
Background Cluster-randomized trials (CRT) are needed to compare interventions that are allocated to entire groups of subjects, rather than to individuals. Publications about CRT have become steadily more common over the past decade. Readers of such publications should be able to categorize and interpret the findings of CRT correctly while considering the methodological requirements applicable to this type of study. Methods This review is based on a selection of pertinent literature and on the authors' expertise. CRT-specific methodological aspects of the planning, performance, and interpretation of studies are discussed. Results Readers of publications on CRT should check whether due consi…
Rare Cancers Europe (RCE) methodological recommendations for clinical studies in rare cancers: A European consensus position paper
2015
While they account for one-fifth of new cancer cases, rare cancers are difficult to study. A higher than average degree of uncertainty should be accommodated for clinical as well as for population-based decision making. Rules of rational decision making in conditions of uncertainty should be rigorously followed and would need widely informative clinical trials. In principle, any piece of new evidence would need to be exploited in rare cancers. Methodologies to explicitly weigh and combine all the available evidence should be refined, and the Bayesian logic can be instrumental to this end. Likewise, Bayesian-design trials may help optimize the low number of patients liable to be enrolled in …
Quality assessment of randomized controlled trial abstracts on drug therapy of periodontal disease from the abstracts published in dental Science Cit…
2020
Background Randomized controlled trials (RCTs) provide the highest level of evidence and are likely to influence clinical decision-making. This study evaluated the reporting quality of RCT abstracts on drug therapy of periodontal disease and assessed the associated factors. Material and Methods The Pubmed database was searched for periodontal RCTs published in Science Citation Indexed (SCI) dental journals from 2010/01/01 to 2019/07/17. Information was extracted from the abstracts according to a modified Consolidated Standards of Reporting Trials (CONSORT) guideline checklist. The data was analyzed using descriptive statistical analysis and the statistical associations were examined using t…
Methodological aspects of clinical trials in tinnitus: a proposal for an international standard
2012
Abstract: Chronic tinnitus is a common condition with a high burden of disease. While many different treatments are used in clinical practice, the evidence for the efficacy of these treatments is low and the variance of treatment response between individuals is high. This is most likely due to the great heterogeneity of tinnitus with respect to clinical features as well as underlying pathophysiological mechanisms. There is a clear need to find effective treatment options in tinnitus, however, clinical trials differ substantially with respect to methodological quality and design. Consequently, the conclusions that can be derived from these studies are limited and jeopardize comparison betwee…
Epidemiology and Reporting Characteristics of Systematic Reviews of Biomedical Research: A Cross-Sectional Study.
2016
Background Systematic reviews (SRs) can help decision makers interpret the deluge of published biomedical literature. However, a SR may be of limited use if the methods used to conduct the SR are flawed, and reporting of the SR is incomplete. To our knowledge, since 2004 there has been no cross-sectional study of the prevalence, focus, and completeness of reporting of SRs across different specialties. Therefore, the aim of our study was to investigate the epidemiological and reporting characteristics of a more recent cross-section of SRs. Methods and Findings We searched MEDLINE to identify potentially eligible SRs indexed during the month of February 2014. Citations were screened using pre…
Research in disaster settings: a systematic qualitative review of ethical guidelines
2016
Background Conducting research during or in the aftermath of disasters poses many specific practical and ethical challenges. This is particularly the case with research involving human subjects. The extraordinary circumstances of research conducted in disaster settings require appropriate regulations to ensure the protection of human participants. The goal of this study is to systematically and qualitatively review the existing ethical guidelines for disaster research by using the constant comparative method (CCM). Methods We performed a systematic qualitative review of disaster research ethics guidelines to collect and compare existing regulations. Guidelines were identified by a three-tie…
When, why, and how to perform wire-based antegrade dissection and reentry technique
2022
Antegrade dissection and reentry (ADR) refers to an attempt to cross a coronary chronic total occlusion (CTO) lesion through wire and/or equipment passage in the subintimal space followed by reentry to the distal true lumen. From the original subintimal tracking and reentry (STAR) technique description by Colombo in 2005, refinement of the technique, improved characteristics of the microcatheters and wires, and better understanding of subadventitial vessel trauma have led to higher success rates, lower complications rates, and improved long-term outcomes. In this chapter, we discuss the technique, its outcomes, and limitations.
Guías EAU sobre incontinencia urinaria
2011
Contexto: Las primeras directrices sobre incontinencia de la European Association of Urology (EAU) se publicaron en 2001. Dichas directrices se han actualizado con regularidad en los últimos años. Objetivo: El objetivo de este artículo es ofrecer un resumen de la actualización de las directrices sobre incontinencia urinaria (IU) de la EAU realizada en 2009. Recogida de evidencias: El comité de trabajo de la EAU formó parte de la IV Consulta Internacional sobre Incontinencia (ICI) y, con permiso de la ICI, llevó a cabo la extracción de la información de relevancia. La metodología de la IV ICI consistió en una amplia revisión de la literatura por parte de expertos internacionales y en la crea…
AISF position paper on liver transplantation and pregnancy: Women in Hepatology Group, Italian Association for the Study of the Liver (AISF)
2016
After the first successful pregnancy in a liver transplant recipient in 1978, much evidence has accumulated on the course, outcomes and management strategies of pregnancy following liver transplantation. Generally, liver transplantation restores sexual function and fertility as early as a few months after transplant. Considering that one third of all liver transplant recipients are women, that approximately one-third of them are of reproductive age (18-49 years), and that 15% of female liver transplant recipients are paediatric patients who have a >70% probability of reaching reproductive age, the issue of pregnancy after liver transplantation is rather relevant, and obstetricians, paedi…
