A socio-ecological approach to physical activity interventions in childcare: a systematic review
2014
The promotion of physical activity (PA) in young children requires effective interventions. This article reviews the evidence on PA interventions in childcare by applying a socio-ecological approach. A computer-based literature search for intervention studies aimed at increasing children's PA levels was run across four databases: SPORTDiscus, ISI Web of Science, PsycINFO and ERIC. The participants had to be in childcare, aged 2-6-year-old, and their pre- and post- intervention PA levels measured. Selection was restricted to peer-reviewed publications and to studies conducted in childcare settings. Twenty-three studies met the inclusion criteria and their methodological quality was assessed.…
Big Data in Medical Science–a Biostatistical View
2015
Big data” is a universal buzzword in business and science, referring to the retrieval and handling of ever-growing amounts of information. It can be assumed, for example, that a typical hospital generates hundreds of terabytes (1 TB = 1012 bytes) of data annually in the course of patient care (1). For instance, exome sequencing, which results in 5 gigabytes (1 GB = 109 bytes) of data per patient, is on the way to becoming routine (2). The analysis of such enormous volumes of information, i.e., organization and description of the data and the drawing of (scientifically valid) conclusions, can already hardly be accomplished with the traditional tools of computer science and statistics. For ex…
Impaired glutathione redox status is associated with decreased survival in two organophosphate-poisoned marine bivalves
2002
Biomonitoring organophosphate (OP) exposure in marine environments is generally achieved by the measurement of acetylcholinesterase activity in bivalves like mussels. However, there is evidence that indicates that oxidative stress may be implied in OP toxicity. The aim of this study was to evaluate the relationship between survival from the OP insecticide fenitrothion and glutathione levels in marine bivalves. Mussels (Mytilus galloprovincialis Lam.) and scallops (Flexopecten flexuosus Poli) were exposed, in a time to death test, to their LC85 of fenitrothion for 96 h. OP-poisoned mussels showed reduced (GSH) and oxidised (GSSG) glutathione depletion in the digestive gland, muscle and gills…
Possible synergic action of non-steroidal anti-inflammatory drugs and glucosamine sulfate for the treatment of knee osteoarthritis: a scoping review
2022
Abstract Background Several studies have reported that glucosamine sulfate (GS) can improve knee osteoarthritis (OA) symptomatology. In parallel, the disease-modifying effects of non-steroidal anti-inflammatory drugs (NSAIDs) in knee OA have also been investigated. However, limited literature has reported the combined effect of GS and NSAIDs. The aim of this scoping review is to describe the scope and volume of the literature investigating the potential benefits and synergistic effect of a combination of GS and NSAIDs in patients with knee OA. Methods PubMed and Embase were searched for studies published from inception through April 2022, evaluating the effects of the combination of GS and …
Behavioral medicine interventions in diabetes.
2010
Poor glycemic control is prevalent in the majority of patients with diabetes and has a strong impact on medical as well as psychological outcomes. Psychological and behavioral variables are of particular interest, as the patients themselves are the most determining factor of treatment success. Consequently, a wide range of behavioral medicine interventions are aimed at improvement in diabetes self-management, coping strategies, blood glucose awareness, and stress reduction. This review provides an overview of randomized controlled trials (RCTs) published in the past 18 months (from March 2008 to September 2009) that evaluated behavioral medicine interventions in patients with diabetes. The …
Metabolomics discloses donor liver biomarkers associated with early allograft dysfunction
2014
Background & Aims Early allograft dysfunction (EAD) dramatically influences graft and patient outcome after orthotopic liver transplantation and its incidence is strongly determined by donor liver quality. Nevertheless, objective biomarkers, which can assess graft quality and anticipate organ function, are still lacking. This study aims to investigate whether there is a preoperative donor liver metabolomic biosignature associated with EAD. Methods A comprehensive metabolomic profiling of 124 donor liver biopsies collected before transplantation was performed by mass spectrometry coupled to liquid chromatography. Donor liver grafts were classified into two groups: showing EAD and immediate g…
Pharmacogenetic considerations for optimizing tacrolimus dosing in liver and kidney transplant patients
2013
The introduction of tacrolimus in clinical practice has improved patient survival after organ transplant. However, despite the long use of tacrolimus in clinical practice, the best way to use this agent is still a matter of intense debate. The start of the genomic era has generated new research areas, such as pharmacogenetics, which studies the variability of drug response in relation to the genetic factors involved in the processes responsible for the pharmacokinetics and/or the action mechanism of a drug in the body. This variability seems to be correlated with the presence of genetic polymorphisms. Genotyping is an attractive option especially for the initiation of the dosing of tacrolim…
Effect of CYP3A5*3 on kidney transplant recipients treated with tacrolimus: a systematic review and meta-analysis of observational studies
2014
The highly variable pharmacokinetics of tacrolimus can hamper the optimal management of kidney transplant patients. This variability has been attributed to the genetic polymorphism of CYP3A5 6986A>G, but the evidence is not clear. We conducted a meta-analysis of studies evaluating the effect of CYP3A5 polymorphism on kidney transplant recipients with tacrolimus plasma concentration divided by daily dose per body weight (C/D) and clinical outcomes. We searched in MEDLINE and EMBASE. We found evidence suggesting a significantly lower C/D among CYP3A5*1 allele carriers compared with carriers of the CYP3A5*3/*3 genotype at weeks 1 and 2, and months 1, 3, 6 and 12. We demonstrated that the expre…
Corticosteroid-free immunosuppression in liver transplantation: a meta-analysis and meta-regression of outcomes.
2009
To examine the impact of steroid withdrawal from the immunosuppression protocols in liver transplantation. The electronic databases Medline, Embase, Pubmed and the Cochrane Library were searched. Meta-analysis pooled the effects of outcomes of a total of 2590 patients enrolled into 21 randomized controlled trials (RCTs), using classic and modern meta-analytic methods. Meta-analysis of RCTs addressing patients transplanted for any indication showed no differences between corticosteroid-free immunosuppression and steroid-based protocols in most of the analyzed outcomes. More importantly, steroid-free cohorts appeared to benefit in terms of de novo diabetes mellitus development [R.R = 1.86 (1.…
