Herbal medications for anxiety, depression, pain, nausea and vomiting related to preoperative surgical patients: a systematic review and meta-analysi…

2019

ObjectiveTo summarise the effects of herbal medications for the prevention of anxiety, depression, pain, and postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic, obstetrical/gynaecological or cardiovascular surgical procedures.MethodsSearches of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and LILACS up until January 2018 were performed to identify randomised controlled trials (RCTs). We included RCTs or quasi-RCTs evaluating any herbal medication among adults undergoing laparoscopic, obstetrical/gynaecological or cardiovascular surgeries. The primary outcomes were anxiety, depression, pain and PONV. We used the Grading of Recommendations Assessme…

Definitive Abutments Placed at Implant Insertion and Never Removed: Is It an Effective Approach? A Systematic Review and Meta-Analysis of Randomized …

2017

Purpose To assess whether repeated abutment disconnections and reconnections have any impact on peri-implant bone resorption and soft tissue healing. Materials and Methods Electronic and manual searches were conducted for English-language articles published up to March 2017 that identified a relation between repeated disconnections of implant abutments (PA group) and prosthetic or implant failures, complications, marginal bone loss (MBL), soft tissue healing, and esthetic evaluation (pink esthetic score [PES]) after at least 1 year of function compared with implants receiving a final abutment at the time of implant placement (DA group). Results Fourteen articles (535 patients with 994 impla…

Predicting mortality with cardiac troponins: recent insights from meta-analyses.

2019

Abstract The introduction of cardiac troponin (cTn) testing in clinical practice has been one of the most important breakthroughs that have occurred in the recent history of laboratory medicine. Although it is now uncontestable that cTn values are essential for diagnosing acute coronary syndrome (ACS), solid evidence is also emerging that assessment of either cardiac troponin I (cTnI) or T (cTnT) may provide valuable prognostic information in the general healthy population, as well as in patients with a vast array of cardiac and extra-cardiac diseases. We have hence performed a critical review of the scientific literature for identifying meta-analyses which have investigated the potential c…

The effect of off-pump coronary artery bypass on mortality after acute coronary syndrome: A meta-analysis

2012

Background Patients requiring surgical revascularisation for acute coronary syndrome (ACS) form a clinically heterogeneous group ranging from haemodynamic stability to cardiogenic shock. Whilst 'off-pump' revascularisation (OPCAB) is often considered, patient selection and operative timing remain controversial. This study aims to identify whether OPCAB may confer a mortality benefit over ONCAB in revascularisation for ACS. Secondly, we review the impact of OPCAB on completeness of revascularisation (CR) and long-term re-intervention. Methods A systematic literature review identified 9 studies (1 randomised controlled trial) of which 8 fulfilled criteria for meta-analysis. Outcomes for a tot…

Prevalence of attention deficit hyperactivity disorder among children and adolescents in Spain: a systematic review and meta-analysis of epidemiologi…

2012

Abstract Background Attention deficit hyperactivity disorder (ADHD) is a commonly diagnosed neuropsychiatric disorder in childhood, but the frequency of the condition is not well established in many countries. The aim of the present study was to quantify the overall prevalence of ADHD among children and adolescents in Spain by means of a systematic review and meta-analysis. Methods PubMed/MEDLINE, IME, IBECS and TESEO were comprehensively searched. Original reports were selected if they provided data on prevalence estimates of ADHD among people under 18 years old in Spain and were cross-sectional, observational epidemiological studies. Information from included studies was systematically ex…

Efficacy of sublingual immunotherapy with grass allergens for seasonal allergic rhinitis: A systematic review and meta-analysis

2010

Background The benefit of sublingual immunotherapy (SLIT) with grass allergens for seasonal allergic rhinitis has been extensively studied, but data on efficacy are still equivocal. Objective To assess the effectiveness of SLIT with grass allergens in the reduction of symptoms and medication in patients with seasonal allergic rhinitis to grass pollen. Methods Computerized bibliographic searches of MEDLINE (1995-2010) were supplemented by hand searches of reference lists. Studies were included if they were double-blind randomized controlled trials (RCTs) comparing SLIT to placebo and if they included patients with history of allergy to grass pollen treated with natural grass pollen extracts.…

Serotonin transporter gene polymorphism in eating disorders: Data from a new biobank and META-analysis of previous studies.

2016

Objectives Growing interest focuses on the association between 5-HTTLPR polymorphism and eating disorders (ED), but published findings have been conflicting. Methods The Italian BIO.VE.D.A. biobank provided 976 samples (735 ED patients and 241 controls) for genotyping. We conducted a literature search of studies published up to 1 April 2015, including studies reporting on 5HTTLPR genotype and allele frequencies in obesity and/or ED. We ran a meta-analysis, including data from BIO.VE.D.A. – comparing low and high-functioning genotype and allele frequencies in ED vs. controls. Results Data from 21 studies, plus BIO.VE.D.A., were extracted providing information from 3,736 patients and 2,707 co…

Anorexia nervosa and cancer: a protocol for a systematic review and meta-analysis of observational studies

2017

BACKGROUND: Anorexia nervosa is characterized by a severe restriction of caloric intake, low body weight, fear of gaining weight or of becoming fat, and disturbance of body image. Pathogenesis of the disorder may include genetic predisposition, hormonal changes and a combination of environmental, psychosocial, and cultural factors. Cancer is the second leading cause of death worldwide. At present, no systematic reviews and meta-analyses have evaluated the risk of cancer in people with anorexia nervosa. The objective of this study will be to evaluate the association between anorexia nervosa and the risk of developing or dying from cancer. METHODS/DESIGN: This study protocol is part of a syst…

Task-sharing interventions for patients with anorexia nervosa or their carers: a systematic evaluation of the literature and meta-analysis of outcome…

2019

The eating disorder clinical and scientific community advocates for the use of a shared approach to healthcare that actively involves patients and carers. A systematic review of the literature on guided self-help or self-help in anorexia nervosa (targeting either the individual affected by the illness or their carers) and meta-analyses of studies using randomised controlled designs for the evaluation of the outcomes: (1) drop-out from end-of-treatment assessment, (2) body mass index (BMI), (3) anxiety, (4) depression and (5) quality of life, were undertaken. Guided self-help was directed to patients in 15 studies and to carers in seven studies. The interventions were based on a variety of t…
