Burnout and depression among Spanish periodontology practitioners.
2009
Objectives: The objective of this study was to determine the prevalence of burnout syndrome and depression symptoms among periodontology practitioners, as well as the relationship with socio-demographic variables and work stress. Study Design: A total of 284 subjects, members of the Spanish Society of Periodontology (SEPA), were selected for this study. The Spanish version of the Maslach Burnout Inventory (MBI) and the Tetradimensional Estructural Questionnaire for Depression (TEC-DE) were sent by post to all participants. Descriptive statistics in addition to mean comparison and chi-square test were used for data analysis. Results: A response rate of 59.85% was obtained. From the total sam…
Prevalence and characteristics of coronary artery disease in a population with suspected ischaemic heart disease using CT coronary angiography: corre…
2008
Purpose. This study was undertaken to describe the correlation between the distribution of coronary artery disease (CAD) in a symptomatic population with suspected ischaemic heart disease, cardiovascular risk factors (RF) and clinical presentation. Materials and methods. We studied 163 patients (mean age 65.5 years; 101 men and 62 women) referred for multidetector computed tomography coronary angiography (MDCT-CA) to rule out CAD. The patients had no prior history of revascularisation or myocardial infarction. We analysed how the characteristics of CAD (severity and type of plaque) can change with the increase in RF and how they are related to different clinical presentations. Results. Pati…
Meta-analysis of genome-wide association studies of attention-deficit/hyperactivity disorder
2010
Contains fulltext : 87688.pdf (Publisher’s version ) (Closed access) OBJECTIVE: Although twin and family studies have shown attention-deficit/hyperactivity disorder (ADHD) to be highly heritable, genetic variants influencing the trait at a genome-wide significant level have yet to be identified. As prior genome-wide association studies (GWAS) have not yielded significant results, we conducted a meta-analysis of existing studies to boost statistical power. METHOD: We used data from four projects: a) the Children's Hospital of Philadelphia (CHOP); b) phase I of the International Multicenter ADHD Genetics project (IMAGE); c) phase II of IMAGE (IMAGE II); and d) the Pfizer-funded study from the…
Rise and fall of HCV-related hepatocellular carcinoma in Italy: a long-term survey from the ITA.LI.CA centres
2013
Background & Aims Hepatitis C virus (HCV) is the leading aetiological factor of HCC in the western world where, overall, its incidence is increasing, despite data suggesting an initial drop in some areas. The aim of this study was to evaluate epidemiology, clinical features and survival of HCV-related HCC (HCV-HCC) in a wide time range in Italy. Methods Multicentre retrospective study including 3695 patients prospectively recruited by the ITA.LI.CA group. Patients were classified into three subgroups according to aetiology (Group A[GA], pure HCV; Group B[GB], HCV + cofactors; and Group C[GC], non-HCV) and in 5 time cohorts (5 years each), according to the year of diagnosis. Age, gender, Chi…
Midterm follow-up after DC-BEAD™-TACE of Hepatocellular Carcinoma (HCC)
2012
Abstract Aim To determine local response, its predictors and survival and complication rates after DC-Bead™-TACE in patients with hepatocellular carcinoma (HCC). Materials and methods DC-Beads™ are non-resorbable, polyvinyl-alcoholic hydrophilic microspheres. They release high amounts of chemotherapeutics directly into the tumour. Delivery is sustained over time, tumour feeders are embolised. We used beads from 100–300 to 500–700 μm loaded with Doxorubicin (max. 150 mg/4 ml). Fifty patients (mean age: 68.5 ± 8.8 years) with HCC were analysed. DC-Bead™-TACE was performed once or repeated in two-month intervals. Imaging scans (CT or MRI) were done one-month following each procedure. To evalua…
Detection of Myocardial Infarction by Cardiac Magnetic Resonance in Embolic Stroke Related to First Diagnosed Atrial Fibrillation
2021
Elevated troponin levels are found in a significant number of patients who are diagnosed with acute embolic stroke (AES) after first diagnosed atrial fibrillation (AF). These myocardial injuries, which are known as cardiocerebral infarction (CCI), are potentially caused by coronary embolism and correspond to simultaneous cardiac and cerebral embolisms. However, this severe condition remains poorly understood. In this prospective study, we aimed to investigate the prevalence and the cardiac magnetic resonance (CMR) characteristics of CCI.Consecutive patients with first diagnosed AF hospitalized for AES in a neurovascular intensive care unit from 2019 to 2020 were included. Troponin Ic kineti…
Hospital admissions for acute myocardial infarction before and after lockdown according to regional prevalence of COVID-19 and patient profile in Fra…
2020
Background The COVID-19 pandemic has had a profound effect on general health care. We aimed to evaluate the effect of a nationwide lockdown in France on admissions to hospital for acute myocardial infarction, by patient characteristics and regional prevalence of the pandemic. Methods In this registry study, we collected data from 21 centres participating in the ongoing French Cohort of Myocardial Infarction Evaluation (FRENCHIE) registry, which collects data from all patients admitted for ST segment elevation myocardial infarction (STEMI) or non-ST segment elevation myocardial infarction (NSTEMI) within 48 h of symptom onset. We analysed weekly hospital admissions over 8 weeks: the 4 weeks …
Relevance of depression for anticoagulation management in a routine medical care setting: results from the ThrombEVAL study program
2014
Summary Background Depressive symptoms have detrimental effects on quality of life and mortality. Poor adherence to a treatment regimen is a potential mechanism for the increased risk of adverse medical events associated with depression. Regarding oral anticoagulation with vitamin K antagonists, adherence is crucial for the outcome. Little is known about the clinical relevance of current depressiveness for anticoagulation treatment. Objectives To examine the impact of current depressiveness on anticoagulation treatment in regular medical care. Patients/Methods We examined the association between clinically significant depressiveness as assessed by the Patient Health Questionnaire-2 ≥ 2 (PHQ…
Prevalence of renal failure and use of antithrombotic prophylaxis among medical inpatients at increased risk of venous thromboembolic events.
2007
Abstract Background Evidence-based guidelines recommend the use of antithrombotic prophylaxis in medical patients at risk of venous thromboembolism (VTE). Low molecular weight heparins (LMWHs) are usually preferred to unfractionated heparin. However, when prophylactic doses of LMWH are administered, patients with renal failure (RF) are exposed to the risk of excessive accumulation, and thus to an increased risk of bleeding. We aimed to assess the prevalence of RF among medical inpatients at increased risk of VTE and the use and dosage of antithrombotic prophylaxis in these patients. Methods In a cross sectional study carried out at three different hospitals, information on all medical inpat…
Results of the Dyslipidemia International Study (DYSIS)-Middle East: Clinical Perspective on the Prevalence and Characteristics of Lipid Abnormalitie…
2013
BACKGROUND: Therapeutic intervention with low-density lipoprotein cholesterol-lowering agents known as statins has been demonstrated to reduce cardiovascular risk. However, many patients on statin treatment have persistent dyslipidemia and remain at a high risk of cardiovascular disease. Therefore, the objective of this study was to assess the frequency of lipid abnormalities in patients receiving chronic statin treatment. METHODS: As part of an international, cross-sectional, observational study, DYSIS-Middle East enrolled 2,182 patients in the United Arab Emirates (UAE), Saudi Arabia, Lebanon and Jordan. All patients were over 45 years of age and had been on statin treatment for at least …
