Information management and complementary alternative medicine: the anatomy of information about CAMs through PubMed
2013
In recent years, there has been a growing interest about complementary and alternative medicine (CAM), and the use of CAM interventions has become more common among people. For these reasons, health professionals must be able to effectively manage information in this field of knowledge according to an evidence-based point of view. This study assessed the anatomy of the available information about CAMs using PubMed, to give practical instructions to manage information in this field. We also analyzed the anatomy of information according to each alternative medicine branch, narrow and broad search methods, subset filters for indexed-for-Medline and non-indexed citations, and different publicat…
Ensuring content validity of psychological and educational tests – the role of experts
2020
Many test developers try to ensure the content validity of their tests by having external experts review the items in terms of relevance, difficulty, clarity, and so on. Although this approach is widely accepted, a closer look reveals there are several pitfalls that need to be avoided if experts’ advice is to be truly helpful. First, I offer a classification of tasks experts are given by test developers as reported on in the literature dealing with procedures of drawing on experts’ advice. Second, I review a sample of reports on test development (N = 72) to identify the common current procedures for selecting and consulting experts. Results indicate that often the choice of experts seems to…
Interpersonal difficulties in obesity: A systematic review and meta-analysis to inform a rejection sensitivity-based model
2019
Abstract Obesity is associated with difficulties due to stigma and loneliness. These impact negatively on individuals’ quality of life and behaviour change efforts. Increased sensitivity to others’ negative feedback might play a role in the maintenance of these difficulties and could be addressed in psychological interventions. We conducted a systematic review of interpersonal difficulties in individuals with obesity, across the lifespan. We investigated early interpersonal adversity (i.e. frequency of teasing/bullying), perceived interpersonal stress and quality of social life, based on a rejection sensitivity model. The databases PubMed, Web of Knowledge and AGRIS, Embase, Medline and Psy…
Un análisis empírico del impacto de la regulación contable en el mercado de auditoría
2017
El objetivo de la presente tesis se centra en el estudio de la estructura del mercado de la auditoría así como en analizar el impacto económico que la regulación contable ejerce sobre determinados elementos del mercado de auditoría (honorarios y rentabilidad de las firmas de auditoría). A partir de la publicación del Reglamento europeo 1606/2002 se requirió a los grupos cotizados que formulasen sus estados financieros consolidados desde el 1 de enero de 2005, conforme a las Normas Internacionales de Información Financiera o NIIF. En España, la adaptación de las NIIF al resto de empresas, no se llevó a cabo hasta la aprobación del Nuevo Plan General Contable (NPGC) y del plan para pequeñas y…
Transient Focal Neurological Events in Cerebral Amyloid Angiopathy and the Long-term Risk of Intracerebral Hemorrhage and Death: A Systematic Review …
2021
Importance Transient focal neurological episodes (TFNEs) are a frequently overlooked presentation of cerebral amyloid angiopathy (CAA), a condition with prognostic implications that are still not well described. Objective To perform a systematic review and meta-analysis to examine the factors associated with incident lobar intracerebral hemorrhage (ICH) and death in patients with CAA presenting with TFNEs. Data Sources A systematic review and individual participant meta-analysis including (1) a hospital-based cohort and (2) the results obtained from a systematic search performed in MEDLINE and Embase completed in December 2019. Study Selection Included studies were observational reports of …
Effect of pistachio on brachial artery diameter and flow-mediated dilatation: A systematic review and meta-analysis of randomized, controlled-feeding…
2017
Background: Results of previous clinical trials evaluating the effect of pistachio supplementation on endothelial reactivity (ER) are controversial. Aims: We aimed to assess the impact of pistachio on ER through systematic review of literature and meta-analysis of available randomized, controlled-feeding clinical studies (RCTs). Methods: The literature search included SCOPUS, PubMed-Medline, ISI Web of Science and Google Scholar databases up to 1st August 2017 to identify RCTs investigating the impact of pistachio on ER. Two independent reviewers extracted data on study characteristics, methods and outcomes. Overall, the impact of pistachio on ER was reported in 4 trials. Results: The meta-…
Effects of balance training on functionality, ankle instability, and dynamic balance outcomes in people with chronic ankle instability: Systematic re…
2021
Aim: To identify the effects of balance and strength training on function, ankle instability and dynamic balance in people with chronic ankle instability. Method: The search was conducted on randomized controlled trials that investigated the effects of balance training or strength training in people with chronic ankle instability compared to a control group. Therefore, a systematic electronic search was performed until April 2021 in Pubmed/MEDLINE, Cochrane, and Embase databases. Moreover, an additional search was further performed checking the reference lists of the selected articles. The main outcomes were ankle instability, functionality, and dynamic balance. Finally, a qualitative and q…
Innovation in endocrine surgery: robotic versus laparoscopic adrenalectomy. Meta-analysis and systematic literature review.
2017
Several studies in the last years demonstrated the better surgical outcome of laparoscopic approach to adrenal gland. Laparoscopic surgery is more difficult to learn and requires different psychomotor skills than open surgery, especially with regard to complex maneuvers requiring precision and dexterity. The development of robotic platform with three-dimensional vision and increased degrees of freedom of the surgical instruments has the aim to overcome these problems. We performed a systematic literature review with meta-analysis to evaluate preoperative data and surgical outcomes of robotic adrenalectomy compared with laparoscopic technique. In September 2016 we performed a systematic lite…
Serum leptin level as a diagnostic and prognostic marker in infectious diseases and sepsis: A comprehensive literature review.
2021
Abstract Background: Infections and sepsis are common causes of morbidity and mortality, with an increasing incidence worldwide. Leptin is involved in the inflammatory process and may modulate the cytokine production, immune cell proliferation and endothelial function. There are conflicting results regarding alterations of leptin levels in infectious diseases and the outcome from sepsis. The aim of the current article is to provide an overview of the medical literature on the correlations between variations of leptin levels and infectious diseases and sepsis. Methods: We performed an extensive literature search in PubMed and Google Scholar databases, using keywords to identify articles rela…
Survival time and differences between dementia with Lewy bodies and Alzheimer’s disease following diagnosis: a meta-analysis of longitudinal studies.
2019
Objective: To synthesize the evidence across longitudinal studies comparing survival in dementia with Lewy bodies (DLB) and Alzheimer's disease (AD). Methods: We conducted a systematic review and meta-analysis of studies comparing survival in clinically diagnosed DLB to AD. Longitudinal cohort studies were identified through a systematic search of major electronic databases from inception to May 2018. A random effects meta-analysis was performed to calculate survival time and relative risk of death. Results: Overall, 11 studies were identified including 22,952 patients with dementia: 2029 with DLB (mean diagnosis age 76.3; 47% female) compared with 20,923 with AD (mean diagnosis age 77.2; 6…
