Prognostic Value of White Blood Cell Count in Acute Myocardial Infarction: Long-Term Mortality
2005
Although traditionally an elevated white blood cell count (WBC), an indicator of systemic inflammation, has been accepted as part of the healing response following acute myocardial infarction (AMI), it has frequently been shown to be a predictor of adverse cardiovascular events. The present study was designed to assess the association between WBC and long-term mortality in AMI patients either with ST-segment elevation (STEMI) or without ST-segment elevation (non-STEMI). Patients and method. The study included 1118 consecutive patients who were admitted with the diagnosis of AMI: 569 non-STEMI and 549 STEMI. The WBC was measured in the 24 hours following admission. Patients were divided into…
Serum 25-hydroxyvitamin D and the incidence of peripheral artery disease in the elderly: The Pro.V.A study
2015
Aim: This study was conducted to examine whether low serum levels of 25-hydroxyvitamin D (250HD) are associated with a higher risk of incident peripheral artery disease (PAD) in a representative group of elderly people. Methods: We followed 1568 community-dwelling elderly participants without PAD at the baseline among a sample of 2097 initially eligible over a mean of 4.4 years as part of the Progetto Veneto Anziani (Pro.V.A.) study. The baseline serum 250HD levels were categorized as <24, 25-49, 50-74, >75 nmol/L, and incident PAD was defined as an ankle-brachial index below 0.9. Results: At the baseline, there were no differences in known risk factors for PAD (BMI), waist circumfere…
Geo-Epidemiology of Age-Related Macular Degeneration: New Clues Into the Pathogenesis
2015
Abstract PURPOSE: To evaluate the demographic, geographic, and race-related variables that account for geographic variability in prevalence rates of age-related macular degeneration (AMD). DESIGN: Systematic review, meta-regression, and decision-tree analysis. METHODS: A systematic literature review of PubMed, Medline, Web of Science, and Embase databases identified population-based studies on the prevalence of AMD published before May 2014. Only population-based studies that took place in a spatially explicit geographic area that could be geolocalized, and used retinal photographs and standardized grading classifications, were included. Latitude and longitude data (geolocalization) and the…
Associations of greenness, greyness and air pollution exposure with children's health: a cross-sectional study in Southern Italy
2018
Background Due to the complex interplay among different urban-related exposures, a comprehensive approach is advisable to estimate the health effects. We simultaneously assessed the effect of “green”, “grey” and air pollution exposure on respiratory/allergic conditions and general symptoms in schoolchildren. Methods This study involved 219 schoolchildren (8–10 years) of the Municipality of Palermo, Italy. Data were collected through questionnaires self-administered by parents and children. Exposures to greenness and greyness at the home addresses were measured using the normalized difference vegetation index (NDVI), residential surrounding greyness (RSG) and the CORINE land-cover classes (C…
Risk Factors of Coronary Artery Disease in Secondary Prevention—Results from the AtheroGene—Study
2015
Background Risk factors are important in cardiovascular (CV) medicine for risk stratification of patients. We aimed to compare the traditional risk factors to clinical variables for the prediction of secondary cardiovascular events. Methods and Results For this study, 3229 patients with known coronary artery disease (CAD) were included. We calculated whether the traditional risk factors, diabetes mellitus, increased LDL/HDL ratio, arterial hypertension and smoking alone and in combination with the clinical variables, ejection fraction, creatinine clearance, multi-vessel disease and CRP concentration predict the outcome cardiovascular death or non-fatal myocardial infarction (N = 432) during…
Scores for functional disability in patients with rheumatoid arthritis are correlated at higher levels with pain scores than with radiographic scores
2000
Objective To analyze correlations of functional disability scores with other measures of clinical status, in particular, Larsen radiographic scores and pain scores, in patients with rheumatoid arthritis (RA). Methods The functional capacity of 141 patients with RA (102 women, 39 men; median age 57 years; median disease duration 11.8 years; 83% rheumatoid factor positive) was assessed according to the Stanford Health Assessment Questionnaire (HAQ). Other variables studied included Larsen scores for radiographic damage of the small joints of the hands, wrists, and feet, pain scores by visual analog scale (VAS), Disease Activity Scores, general health scores by VAS, and Beck Depression Invento…
What makes music memorable? : Relationships between acoustic musical features and music-evoked emotions and memories in older adults
2021
Publisher: Public Library of Science; International audience; Music has a unique capacity to evoke both strong emotions and vivid autobiographical memories. Previous music information retrieval (MIR) studies have shown that the emotional experience of music is influenced by a combination of musical features, including tonal, rhythmic, and loudness features. Here, our aim was to explore the relationship between music-evoked emotions and music-evoked memories and how musical features (derived with MIR) can predict them both. Methods Healthy older adults (N = 113, age ≥ 60 years) participated in a listening task in which they rated a total of 140 song excerpts comprising folk songs and popular…
Clinical and biochemical determinants of the extent of liver steatosis in type 2 diabetes mellitus
2015
Objective Nonalcoholic fatty liver disease is very frequent in both type 2 diabetes mellitus (T2DM) and the metabolic syndrome (MS), which share clinical and metabolic characteristics. Whether and to which extent these characteristics can predict the degree of liver steatosis are not entirely clear. Patients and methods We determined liver fat (divided into four classes) by standard sonographic images, and clinical and biochemical variables, in 60 consecutive patients with T2DM and with features of the MS. We examined both simple and multiple correlations between the degree of liver steatosis and the variables measured. Results Increased liver fat (defined as >5% of liver mass) was detec…
Physical Activity Trends of Finnish Adolescents With Long-Term Illnesses or Disabilities From 2002–2014
2016
Background:Adolescents’ physical activity level is a major source of concern. For adolescents with long-term illnesses or disabilities (LTID), being physically active can prevent secondary conditions. This is one of the first studies reporting trends in physical activity of adolescents with LTID in relation to gender, age, and sports club membership.Methods:Data were collected from the Health Behavior in School-aged Children study in Finland during 2002, 2006, 2010, and 2014. In 13- and 15-year-olds (N = 2206), 17.1% reported having LTID. Daily physical activity recall was the dependent variable. Binary logistic regression analysis was conducted eparately for sports club members (n = 936) a…
DSM-IV Combined Type ADHD Shows Familial Association With Sibling Trait Scores
2008
Contains fulltext : 69060.pdf (Publisher’s version ) (Closed access) Attention deficit hyperactivity disorder (ADHD) is a discrete clinical syndrome characterized by the triad of inattention, hyperactivity, and impulsivity in the context of marked impairments. Molecular genetic studies have been successful in identifying genetic variants associated with ADHD, particularly with DSM-IV inattentive and combined subtypes. Quantitative trait locus (QTL) approaches to linkage and association mapping have yet to be widely used in ADHD research, although twin studies investigating individual differences suggest that genetic liability for ADHD is continuously distributed throughout the population, u…
