Construction of ethics in clinical research: clinical trials registration
Provedor de dados: 80
Autores: Caramori,C. A.
Scientific development that has been achieved through decades finds in clinical research a great possibility of translating findings to human health application. Evidence given by clinical trials allows everyone to have access to the best health services. However, the millionaire world of pharmaceutical industries has stained clinical research with doubt and improbability. Study results (fruits of controlled clinical trials) and scientific publications (selective, manipulated and with wrong conclusions) led to an inappropriate clinical practice, favoring the involved economic aspect. In 2005, the International Committee of Medical Journal Editors (ICMJE), supported by the World Association of Medical Editors, started demanding as a requisite for...

strbee: Randomization-based efficacy estimator
Provedor de dados: 31
Autores: White,   Ian R.; Walker,   Sarah; Babiker,   Abdel.
strbee analyzes a two-group clinical trial with a survival outcome, in which some subjects may “crossover” to receive the treatment of the other arm. Adjustment for treatment crossover is done by a randomization-respecting method that preserves the intention-to-treat p-value.

Bioethical aspects of basic research and medical applications of human stem cells
Provedor de dados: 48
Autores: Santos,Manuel J; Ventura-Juncá,Patricio.
The new discoveries, the extraordinary dynamism in human stem cell (SC) research, and the great expectations of the benefits in clinical treatment of many diseases are on the edge of unparalleled advances in both: 1) the understanding of basic mechanisms of cell differentiation and development and 2) the translation from basic research to new clinical therapies. Human stem cells are obtained from different sources, such as embryo, fetal, and adult tissues, in vitro induction (iPS cells) or transdifferentiation. The evidence that these cells are pluripotent (or multipotent), meaning they have the ability to differentiate into all body tissues or tissues of the same lineage, raises the possibility that they could regenerate diseased or damaged tissue in...

The corporate bias and the molding of prescription practices: the case of hypertension
Provedor de dados: 56
Autores: Fuchs,F.D.
Drug management of hypertension has been a noticeable example of the influence of the pharmaceutical industry on prescription practices. The worldwide leading brands of blood pressure-lowering agents are angiotensin receptor-blocking agents, although they are considered to be simply substitutes of angiotensin-converting enzyme (ACE) inhibitors. Commercial strategies have been based on the results of clinical trials sponsored by drug companies. Most of them presented distortions in their planning, presentation or interpretation that favored the drugs from the sponsor, i.e., corporate bias. Atenolol, an ineffective blood pressure agent in elderly individuals, was the comparator drug in several trials. In a re-analysis of the INSIGHT trial, deaths appeared to...

Corticosteroids in acute respiratory distress syndrome
Provedor de dados: 56
Autores: Fernandes,A.B.S.; Zin,W.A.; Rocco,P.R.M.
Improving the course and outcome of patients with acute respiratory distress syndrome presents a challenge. By understanding the immune status of a patient, physicians can consider manipulating proinflammatory systems more rationally. In this context, corticosteroids could be a therapeutic tool in the armamentarium against acute respiratory distress syndrome. Corticosteroid therapy has been studied in three situations: prevention in high-risk patients, early treatment with high-dose, short-course therapy, and prolonged therapy in unresolving cases. There are differences between the corticosteroid trials of the past and recent trials: today, treatment starts 2-10 days after disease onset in patients that failed to improve; in the past, the corticosteroid...

The anti-obesity potential of Ilex paraguariensis: results from a meta-analysis
Provedor de dados: 60
Autores: Luís,Ângelo Filipe Santos; Domingues,Fernanda da Conceição; Amaral,Luísa Maria Jota Pereira.
The dried leaves of Ilex paraguariensis, also known as yerba mate or chimarrão, are used to produce infusions consumed by over 1 million people worldwide, being a traditional drink in several South American countries, particularly, Argentina, Brazil, Uruguay, and Paraguay. The positive effects of I. paraguariensis in obesity have been described and observed in some clinical trials both in animals and in humans. The main goal of this work was to perform a systematic review, complying with the PRISMA (Preferred Reported Items for Systematic Reviews and Meta-Analysis) recommendations, followed by a meta-analysis and Trial Sequential Analysis (TSA), to summarize the results of the recent clinical trials, clarifying the anti-obesity potential of I....
