In the electromagnetic spectrum, structural damage to living tissues per unit of absorbed energy tends to increase with the decrease of a wavelength which is evident not only for ultraviolet and ionizing radiation but also for the infrared and visible light. By causing thermal damage after absorbing energies that would be harmless for radiofrequency electromagnetic fields (EMF), tissues are eve...

Background. Missed Nursing Care (MNC) is experienced in nearly all health care facilities. Awareness of the aspects involved in the occurrence of MNC can lead to the improvement of the quality of patient care. This systematic review aims to answer the question: "What factors are involved in the incidence of missed nursing care?"   Methods. This systematic review follows the Preferred Reporting...

In combination with randomization, blinding or masking is an important factor in randomized controlled trials (RCTs), particularly in trials that assess therapeutic effects. Here an attempt is made to explain blindness and why it is important. In clinical trials, blinding is defined as the condition imposed on a study in which study participants, health care providers and assessors collecting o...

BACKGROUND The Cochrane risk of bias tool is commonly criticized for having a low reliability. We aimed to investigate whether training of raters, with objective and standardized instructions on how to assess risk of bias, can improve the reliability of the Cochrane risk of bias tool. METHODS In this pilot study, four raters inexperienced in risk of bias assessment were randomly allocated to ...

This study focuses on levels of concern for hurricanes among individuals living along the Gulf Coast during the quiescent two-year period following the exceptionally destructive 2005 hurricane season. A small study of risk perception and optimistic bias was conducted immediately following Hurricanes Katrina and Rita. Two years later, a follow-up was done in which respondents were recontacted. T...

Background: Risk-of-bias assessments are now a standard component of systematic reviews. At present, reviewers need to manually identify relevant parts of research articles for a set of methodological elements that affect the risk of bias, in order to make a riskof-bias judgement for each of these elements. We investigate the use of text mining methods to automate risk-of-bias assessments in sy...

objective: the study was designed to examine explicit memory bias in trait-anxiety and obsessive compulsive disorder. method: memory bias was examined in three groups of subjects: low-trait  anxious (20 subjects), high-trait anxious (20 subjects), and obsessive compulsive patients (20 subjects) in whom danger schema were activated after they were exposed the threat-related material. the trait-a...

OBJECTIVE Despite the increasing numbers of published trials of quality improvement (QI) interventions in diabetes, little is known about the risk of bias in this literature. DESIGN Secondary analysis of a systematic review. DATA SOURCES Medline, the Cochrane Effective Practice and Organisation of Care (EPOC) database (from inception to July 2010) and references of included studies. ELIGI...

Introduction: Previous studies have reported contradicting results about the effect of medication therapy on attribution bias and jumping to conclusion (JTC) bias in schizophrenic patients. This study aims at analyzing the effect of medication on attribution bias and JTC bias in schizophrenic patients. Methods: This study is an ex post facto and casual-comparative research. 28 people includi...
