<title>Refractive properties of separate erythrocytes of Chernobyl clean-up workers at different pH</title>

2000

This study is focused on the modifications in erythrocytes of Chernobyl nuclear power plant accident clean-up workers as a late health effect of short-term impact of high level radioactive contamination. As a result, a new method based on erythrocyte (RBC) refractive index properties at different pH has been elaborated. According to the light dispersion theory for fluids refractive index is associated with molecules mass m. This feature is widely used for estimation of cell dry mass. But there is another refractive index dependency from molecules charge q regardless of its sing. This feature is not being used for cell quantitative and qualitative characterization. In this study, RBC were in…

The objective of this study was to analyze the associations of various individual- and environmental-related factors with subgroups of daily, frequent, moderate and low moderate-to-vigorous physical activity (MVPA) among children and adolescents. Data were obtained from the Finnish School-age Physical Activity (FSPA) study 2016 from 4677 national representative 11-, 13-, and 15-year-old children and adolescents. MVPA and individual- and environmental-related factors were assessed by a questionnaire and analyzed by two-level logistic regression. Seventeen of the twenty-one variables were statistically significantly associated with MVPA. However, only three variables were statistically signif…

Genetic risk profiles for a childhood with severely overweight

2013

Summary What is already known about this subject Genome-wide association studies have identified susceptibility loci, conferring only small effects to obesity. We selected 12 from the most accepted susceptibility genes to overweight, which have been corroborated in different populations and series of thousands of adult individuals. Single-nucleotide polymorphisms variants can have a cumulative effect on common forms of obesity, to create a genetic risk score. What this study adds We concentrated on 109 single-nucleotide polymorphisms (SNPs) located in 12 loci previously reported in association to body mass index at genome-wide significant level, for individuals of European ancestry. To iden…

Assessing the Beneficial Effects of Economic Growth: The Harmonic Growth Index

2011

In this paper we introduce the multidimensional notion of harmonic growth as a situation of diffused well-being associated to an increase of per capita GDP. We say that a country experienced a harmonic growth if during the observed period all the key indicators, proxies of the endogenous and exogenous forces driving population well-being, show a significantly common pattern with the income dynamics. The notion is operationalized via an index of time series harmony which follows the functional data analysis approach. This Harmonic Growth Index (HGI) is based on comparisons between the coefficients from cubic B-splines interpolation. Such indices are then synthesized in order to provide the g…

Epidemiology of Mantle Cell Lymphoma: A Population-Based Study in France

2011

Abstract Abstract 5222 Introduction: Mantle cell lymphoma (MCL) is an aggressive and rare B-cell lymphoma entity representing around 5–8% of non-Hodgkin's lymphomas in adults. To our knowledge no data is available on the epidemiology of MCL in France. We aimed to describe incidence, survival and main clinical characteristics of MCL in a French population. Methods: Patients diagnosed with MCL were identified in three administrative areas covered by an haematological malignancies registry: the Côte d'Or (from 1988 to 2008), the Basse-Normandie (from 1997 to 2006) and the Gironde (from 2002 to 2006). Main clinical features and management characteristics were collected. World age-standardised …

Musculoskeletal pain and use of analgesics in relation to mobility limitation among community-dwelling persons aged 75 years and older

2012

Pain and factors related to it constitute serious health problems in the older population. This populationbased cross-sectional study aimed to investigate whether musculoskeletal pain is associated with mobility limitation and whether the relationship between pain and mobility limitation varies according to the use of analgesics among community-dwelling older people. A total of 622 community-dwelling participants aged 75 years and older (mean age 80.4, 74% women) were interviewed about presence and severity of musculoskeletal pain. Self-reported analgesic drug utilization was verified against medical records. Mobility limitation was assessed by the Timed Up & Go test (TUG) time of >13.5 s o…

Fibrinogen plasma levels in an apparently healthy general population: Relation to environmental and genetic determinants

1998

SummaryElevated fibrinogen levels are an independent risk factor for cardiovascular ischemic disease. We investigated the relationship between cardiovascular ischemic risk factors, the fibrinogen Bβ-chain G/A-455 polymorphism and plasma fibrinogen levels in 989 apparently healthy subjects. Fibrinogen values were higher in subjects with C reactive protein (C-RP) > 0.33 mg/dl, BMI > 23.9 kg/m2, total cholesterol > 4.84 mmol/l, triglycerides >1.02 mmol/l, PAI-1 antigen >12.2 ng/ml, carriers of the A allele, first-degree relative history of coronary artery disease, or consuming >10 cigarettes per day (p <0.01). Men and ethanol drinkers showed lower plasma fibrinogen levels …

The Mediating Role of C-Reactive Protein and Handgrip Strength Between Obesity and Walking Limitation

2008

OBJECTIVES: To study the association between different obesity indicators and walking limitation and to examine the role of C-reactive protein (CRP) and handgrip strength in that association. DESIGN: A cross-sectional, population-based study. SETTING: The Health 2000 Survey with a representative sample of the Finnish population. PARTICIPANTS: Subjects aged 55 and older with complete data on body composition, CRP, handgrip strength, and walking limitation (N=2,208). MEASUREMENTS: Body composition, anthropometrics, CRP, medical conditions, handgrip strength, and maximal walking speed were measured in the health examination. Walking limitation was defined as maximal walking speed less than 1.2…

Purpose: Few large-scale population-based studies have adequately examined the relationships between steroid hormones, health status and physical fitness. The purpose of the study was to describe the relationship of serum basal endogenous steroid hormones (testosterone, TES; empirical free testosterone, EFT; cortisol, COR) and sex hormone-binding globulin (SHBG) to body composition, cardiovascular risk factors, and physical fitness in young healthy men. Methods: Male reservists (25±4 yrs, N=846) participated in the study. Basal TES, EFT, COR and SHBG were measured in morning fasted blood. Stepwise regression analyses were used to examine associations between individual hormones to four sepa…
