OBJECTIVE: Percutaneous cholecystostomy (PC) is used for the treatment of acute cholecystitis in patients with high surgical risk due to the severity of cholecystitis and/or the underlying acute or chronic medical comorbidities. The evidence for this strategy is unclear. MATERIALS AND METHODS: We searched PubMed and t…

Despite the lack of evidence that the 'putative human pheromones' androstadienone and estratetraenol ever were pheromones, almost 60 studies have claimed 'significant' results. These are quite possibly false positives and can be best seen as potential examples of the 'reproducibility crisis', sadly common in the rest o…

BACKGROUND: Atraumatic hip pain in children is one of the most common symptoms with which pediatricians, orthopedists, and general practitioners are confronted, with an incidence of 148 cases per 100 000 persons per year. METHODS: This article is based on publications up to April 2019 that were retrieved by a selectiv…

BACKGROUND: Systematic reviews are considered the best design to synthesize all existing information of a given research topic. To date, there is no study that investigated the quality of reporting of systematic reviews relevant to physical therapy published in Portuguese. OBJECTIVE: To analyse the quality of reportin…

Physical activity seems to be an important component of lifestyle interventions for weight loss and maintenance. Although the effects of physical activity on weight loss may seem to be modest, there seems to be a dose-response relationship between physical activity and weight loss. Physical activity also seems to be a…

Randomized controlled clinical trials remain the best method for minimizing bias when evaluating dermatological treatments. Many dermatologic clinical trials have suffered from small sample sizes, selective reporting of outcomes, publication bias, poor reporting, and heterogeneous outcomes that have hampered comparabil…

Coronary revascularisation using cardiopulmonary bypass remains the gold standard treatment for coronary artery disease. Over the past decade, techniques of revascularisation on the beating heart without the use of cardiopulmonary bypass (off-pump surgery) have evolved with an attempt to reduce the potential deleteriou…

The integrity and functional activity of the endothelial monolayer play a critical role in preventing atherosclerotic disease progression. Endothelial cell (EC) damage by atherosclerosis risk factors can result in EC apoptosis with loss of the integrity of the endothelium. Thus, approaches to repair the injured vessels…

Bariatric surgery for the treatment of morbid obesity or overweight refractory to medical therapy was born at the beginning of second half of the twentieth century, and its first steps were uncertain and with a not jet well definite purpose. In fact the main result to be pursued seemed to be simply the reduction of bod…

In an effort to identify priority statements for research into the healthcare of children and adolescents a search of multiple research databases and the Internet was undertaken. There is a considerable body of literature outlining research priorities that are built around specific disorders or specialist services, whi…

Online handwriting recognition is gaining renewed interest owing to the increase of pen computing applications and new pen input devices. The recognition of Chinese characters is different from western handwriting recognition and poses a special challenge. To provide an overview of the technical status and inspire futu…

There is almost universal agreement that the quality of clinical trials of acupuncture is poor. There is an urgent need to improve their quality. The author develops here a list of 45 criteria important in the design, implementation, and writing up of controlled clinical acupuncture trials. This list has been compiled…

BACKGROUND: It is difficult to determine the effectiveness or potential harm of dental therapies. Thus, any tools able to condense reliable scientific information would be of benefit. PURPOSE: To discuss methods for the assessment of the scientific literature and, in particular, of systematic reviews for evaluating th…

Evidence-based medicine is a new paradigm of clinical practice that promotes the collection, interpretation and integration of valid, important and applicable to patients research-derived evidence, and it can improve the efficiency and the effectiveness of health care. Nevertheless research often fails to get in clinic…

BACKGROUND: The unprecedented emergence of the COVID-19 pandemic necessitated the development and global distribution of vaccines, making the understanding of global vaccine acceptance and hesitancy crucial to overcoming barriers to vaccination and achieving widespread immunization. OBJECTIVE: This umbrella review syn…

STATEMENT OF PROBLEM: Several systematic reviews have investigated the clinical performance and patient-reported outcomes of conventionally and digitally fabricated complete dentures, with conflicting results. An overview of these studies is needed. PURPOSE: The purpose of this systematic review was to summarize the s…

OBJECTIVE: To propose a framework for enhancing the reporting quality of genetic association studies by adapting the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. METHODS: A systematic review was performed on case-control and cohort studies published in peer-reviewed journals…

OBJECTIVE: To present an overview to summarize the efficacy and safety of biologics for the treatment of Crohn's disease (CD). METHODS: We gathered systematic reviews or meta-analyses on the efficacy and safety of biologic therapy for CD from the beginning to September 30, 2023, by searching the databases of the Chine…

PURPOSE: Pelvimetry is often recommended in primiparous patients before offering vaginal breech delivery. Later studies show a reduction in perinatal mortality in women undergoing pelvimetry while earlier studies show the opposite. Magnetic resonance imaging (MRI), considered a new technology in 1990, has become the mo…

BACKGROUND: Early child development sets the course for optimal outcomes across life. Increasing numbers of children worldwide are exposed to opioids in pregnancy and frequently live in environments associated with adverse developmental outcomes. Although multiple systematic reviews have been published in this area, th…
