Efficacy of non-surgical periodontal treatment on patients with coronary artery disease: a meta-analysis of randomized controlled trials
2022
Coronary artery disease (CAD) is defined as one of the most common cardiovascular diseases (CVDs). Periodontitis is one of the risk factors for CAD. PubMed, Embase and Cochrane Library databases were carefully and thoroughly retrieved until October 2021. On the basis of the inclusion and exclusion criteria, eligible articles were selected strictly to identify randomized controlled trials (RCTs). Using Cochran's Q statistic, Review Manager 5.4 and Stata 16, data were extracted, and a comprehensive analysis was carried out. Six RCTs of 619 patients were included in this study, including 360 in the intervention group (IG) and 259 in the control group (CG). Meta-analysis showed significant diff…
Scheduling a cellular manufacturing system with GA
2002
The flexible manufacturing cell scheduling problem is considered with a multi-objective approach, pursuing together makespan minimisation and the in process job wait minimisation. The formulation of the scheduling problem is discussed, analysing how to generate well suited sequences, like generalised permutation sequences, and the proper construction of a JIT timing of activities. An evolutionary sequencing algorithm based on both classic genetic operators and hybrid operators is then proposed. The hybrid operators have been introduced to construct highly fit initial population, to perform periodically a local search on the population and to maintain enough genetical diversity in the actual…
Ecological momentary intervention to enhance emotion regulation in healthcare workers via smartphone: a randomized controlled trial protocol
2022
Abstract Background CUIDA-TE is an APP that offers transdiagnostic cognitive behavioral therapy focused on enhancing emotion regulation. As a novelty, it incorporates ecological momentary interventions (EMI), which can provide psychological support in real time, when suffering arises. The main goal of the study is to evaluate the efficacy of CUIDA-TE to improve emotion regulation in healthcare workers, a population that has been particularly emotionally impacted by the COVID-19 pandemic. Methods In this three-arm, randomized controlled trial (RCT) the study sample will be composed of a minimum of 174 healthcare workers. They will be randomly assigned to a 2-month EMI group (CUIDA-TE APP, n …
Palliative sedation in patients with advanced cancer followed at home: A systematic review
2011
Abstract Context Patients with advanced cancer who are near the end of life may experience intolerable suffering refractory to targeted palliative therapies. Palliative sedation (PS) is considered to be an effective treatment modality for these refractory symptoms when aggressive efforts fail to provide relief. Objectives The aim of this study was to systematically review articles regarding PS performed at home in patients with intractable symptoms. Methods Literature databases searched included MedLine, PubMed, and EMBASE. The text words and MeSH/EMTREE terms "home care" and "sedation" were used for electronic database searches. Results Six articles met the inclusion criteria for research …
CEA vs CAS
2009
Objectives: Last years registered an increment in the number of endovascular procedures. Traditional carotid endoarterectomy (CEA) is the most performed surgical treatment for carotid stenosis. In symptomatic patients CEA reduces significantly absolute relative risk of stroke and death. In asymptomatic patients AHA guidelines recommend CEA for stenosis 60–99%, if the risk of perioperative stroke or death is <3%. According to 2007 Clinical Expert Consensus Document Carotid Artery Stenting (CAS) should be used in patients at high-risk for CEA or into controlled trials and Cochrane Database of Systematic Reviews does not support a widespread change in clinical practice away from recommending C…
New antihyperglycaemic agents and cardiovascular disease: let's be optimistic.
2018
Cardiovascular disease (CVD) substantially increases mortality in diabetes mellitus. This narrative review highlights recent research on the putative associations between dipeptyl peptidase 4 inhibitors, glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium glucose co-transporter 2 inhibitors (SGLT-2is) and several cardiovascular risk factors.New antihyperglycaemic agents favourably modulate several CVD risk factors, including fasting and postprandial plasma glucose levels, body weight, blood pressure, lipids, microalbuminuria, nonalcoholic fatty liver disease, serum uric acid, and arterial stiffness. Liraglutide (in LEADER), semaglutide (in SUSTAIN-6), empagliflozin (in EMPA-REG …
Review article: a comparison of glucagon-like peptides 1 and 2.
2013
Summary Background Recent advancements in understanding the roles and functions of glucagon-like peptide 1 (GLP-1) and 2 (GLP-2) have provided a basis for targeting these peptides in therapeutic strategies. Aim To summarise the preclinical and clinical research supporting the discovery of new therapeutic molecules targeting GLP-1 and GLP-2. Methods This review is based on a comprehensive PubMed search, representing literature published during the past 30 years related to GLP-1 and GLP-2. Results Although produced and secreted together primarily from L cells of the intestine in response to ingestion of nutrients, GLP-1 and GLP-2 exhibit distinctive biological functions that are governed by t…
Targeting the vascular endothelial growth factor system to prevent ovarian hyperstimulation syndrome
2008
BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) typically occurs when ovaries are primed with FSH/ LH and subsequently exposed to hCG. The ultimate pathophysiological step underlying this clinical picture is increased vascular permeability (VP). METHODS: A search of the literature was carried out using PubMed and the authors’ files. RESULTS: In rodents and humans, the expression of vascular endothelial growth factor (VEGF) and VEGF receptor 2 (VEGFR-2) mRNA increases during ovarian stimulation. With the administration of hCG, the expression of each rises to a maximum. Expression of VEGF/VEGFR-2 mRNAs correlates with enhanced VP, with both peaking 48 h following an injection of hCG. Imm…
Glucose lowering and anti-atherogenic effects of incretin-based therapies: GLP-1 analogues and DPP-4-inhibitors
2009
Type 2 diabetes is a chronic, progressive disease with a multi-faceted pathophysiology. Beyond the known defects of insulin resistance and beta-cell insufficiency, derangement of incretin hormones normally produced from the gut wall in response to food intake play an important role. In recent years, the 'incretin-based' therapies (IBTs) have been developed to address hyperglycemia through either mimicking the action of the endogenous incretin glucagon-like polypeptide (GLP-1) (GLP-1 receptor agonists) or by inhibiting the activity of the enzyme that degrades GLP-1 (the dipeptyl peptidase-4 inhibitors).We reviewed available evidence on the glucose lowering and anti-atherogenic effects of IBT…
