Dental care in children with Down syndrome : a questionnaire for Belgian dentists
2019
Background To date, research on the opinions of dentists on the oral health care of children with DS (Down Syndrome) is scarce. Material and Methods Evaluate the views and knowledge of Belgium dentists regarding dental care of children with DS. An adequate sample of dentists were invited to fill in a validated questionnaire. Results were assessed in 95% confidence interval with p< 0.05 level. Results A total of 356 questionnaires were returned (177 men, 179 women). Mean age of the dentists was 50.3 years (SD: 11.9) and 75% obtained their degree more than 20 years ago. 72.5% of all dentists replied that they had not been instructed in how to treat children with DS during their dental educati…
Lack of effect of azithromycin on QT interval in children: a cohort study.
2016
Macrolides are a group of antimicrobial drugs used widely, being well known for their adverse cardiac effects. Erythromycin and clarithromycin are most commonly associated with these conditions. In recent years, azithromycin (AZM) has been assessed because of its possible relation to arrhythmias (mainly QT interval prolongation) and risk of cardiovascular death.1 The pharmacodynamics of these effects is complex and the occurrence of cardiovascular death is unpredictable.2 However, all published manuscripts on the cardiac effects of AZM to date are cases in adults or …
Vitamin D Intake and Magnetic Resonance Parameters for Knee Osteoarthritis: Data from the Osteoarthritis Initiative
2018
Purpose: There is evidence that vitamin D may play a role in the osteoarthritis (OA) pathogenesis, but the few data available are limited to X-rays and clinical findings. The aim of this study was to investigate whether a higher intake of vitamin D was associated with a better architecture of the cartilage of the knee, assessed with magnetic resonance (MRI), in a large cohort from North America. Methods: 783 participants (59.8% females; mean age: 62.3 years) with an MRI assessment from the Osteoarthritis Initiative were included. Vitamin D dietary intake was calculated as the sum of food and oral supplementation. A coronal 3D FLASH with Water Excitation MR sequence of the right knees was us…
A comparative study of mortality in agricultural and industrial areas in Spain.
1995
The three main causes of contamination in the industrialized world are energy production, and industrial and agricultural activities. The aim of the present study was to examine changes in cause of death in order to contrast causes of death between agricultural and industrial areas. To this effect we have selected four zones — two predominantly industrial and two mainly agricultural — within the Valencian Community. Mortality figures were gathered corresponding to the same period 1976–1989, published by the Conselleria de Sanitat i Consum of the Generalitat Valenciana (Valencian Community health authorities). Thirty large groups of causes of death were established for posterior analysis. Mo…
Booster vaccination with hexavalent DTPa-HBV-IPV/Hib vaccine in the second year of life is as safe as concomitant DTPa-IPV/Hib + HBV administered sep…
2003
The safety and reactogenicity of a booster dose of GSK Biologicals' hexavalent DTPa-HBV-IPV/Hib vaccine (N=4725) was compared with the separate administration of GSK Biologicals' DTPa-IPV/Hib and HBV vaccines (N=4474) in two open, randomized multicenter studies (A and B). Solicited symptoms occurring within 4 days of vaccination were recorded on diary cards and serious adverse events (SAEs) were collected throughout the study period. In Study A (N=1149), incidences of solicited symptoms were similar in both groups; there were no SAEs either reported within 4 days of vaccination or considered to be causally related to vaccination. In study B (N=8050), where fever was the only solicited sympt…
Variants in COMT and spontaneous smoking cessation: retrospective cohort analysis of 925 cessation events
2009
Genome-wide studies have identified single nucleotide polymorphisms associated with smoking behaviour and nicotine dependence. Less is known about genetic determinants of smoking cessation, but rs4680 in COMT has recently been shown to explain a substantial proportion of the variation in cessation in the general population. We attempted to replicate the reported, clinically relevant effect in a population-based retrospective cohort analysis of 1443 ever-heavy smokers, of whom 925 had reached abstinence. In Cox regression models, neither rs4680 nor two polymorphisms nearby were associated with smoking cessation. The adjusted relative cessation rate (95% confidence interval) in rs4680 methion…
Right ventricular strain assessment by cardiovascular magnetic resonance myocardial feature tracking allows optimized risk stratification in Takotsub…
2018
Background A substantial number of patients with Takotsubo syndrome (TTS) exhibit right ventricular (RV) dysfunction which has been associated with adverse outcome. The aim of this study was to assess the clinical and prognostic value of RV myocardial strain in TTS using cardiovascular magnetic resonance myocardial feature tracking (CMR-FT). Methods CMR-FT was performed in a core laboratory to determine RV longitudinal strain in 134 TTS patients undergoing CMR in median 2 days after admission to 2 experienced centers. For comparison, RV involvement was evaluated by sole visual assessment concerning RV contraction abnormalities. Both approaches were analyzed regarding their long-term prognos…
Relation of Multiple Inflammatory Biomarkers to Incident Atrial Fibrillation
2009
Basic and clinical studies have suggested that inflammation predisposes to atrial fibrillation (AF). We assessed the association of 12 circulating inflammatory biomarkers (i.e., C-reactive protein, fibrinogen, interleukin-6, intercellular adhesion molecule-1, lipoprotein-associated phospholipase A2 [mass and activity], monocyte chemoattractant protein-1, myeloperoxidase, CD40 ligand, osteoprotegerin, P-selectin, and tumor necrosis factor receptor II) with incident AF in 2863 Framingham Offspring Study participants (mean age 60.7 years, SD = 9.4, 55% women). During follow-up (median 6 years), 148 participants (43% women) developed incident AF. In the multivariable proportional hazards models…
Lung ultrasound in outpatients with heart failure: the wet‐to‐dry HF study
2021
The Nancy team is supported by the RHU Fight-HF, a public grant overseen by the French National Research Agency (ANR) as part of the second 'Investissements d'Avenir' programme (reference: ANR-15-RHUS-0004), by the French PIA project 'Lorraine Université d'Excellence' (reference: ANR-15-IDEX-04-LUE), the ANR FOCUS-MR (reference: ANR-15-CE14-0032-01), ERA-CVD EXPERT (reference: ANR-16-ECVD-0002-02), the Contrat de Plan Etat Lorraine IT2MP, and FEDER Lorraine. Aims: In ambulatory patients with chronic heart failure (HF), congestion and decongestion assessment may be challenging. The aim of this study is to assess the value of lung ultrasound (LUS) in outpatients with HF in characterizing deco…
Echocardiographic pulmonary artery pressure estimation and heart failure rehospitalization burden in patients with acute heart failure
2017
Abstract Pulmonary hypertension (PH) is a strong predictor of mortality in patients with heart failure (HF). However, the relationship between PH, through echocardiographic pulmonary artery pressure (PASP) estimation, and the risk of HF rehospitalizations remains unclear. Methods We prospectively included 2343 consecutive patients discharged for acute heart failure (AHF). PH was estimated by echocardiography through PASP determination during the index admission. Patients were categorized as follows across PASP: non-measurable, normal (≤35mmHg), mild (36–45mmHg), moderate (46–60mmHg), or severe PH (>60mmHg). Negative binomial regression method was used to evaluate the association between PAS…
