Serum lipoproteins are not associated with the severity of asthma
2018
Abstract Background Asthma is a chronic inflammatory disorder of the bronchi with a complicated and largely unknown pathogenesis . In this context, an emerging role is attributed to the apolipoproteins which serve as structural components of plasma lipoproteins . Low density lipoproteins (LDL) may be involved in the inflammatory pathways of the asthmatic airways; in particular, small dense LDL (sdLDL) particles were associated with increased oxidative susceptibility compared to medium and large sized LDL. In our previous study, we found a positive correlation between forced expiratory volume 1 s (FEV 1) % predicted and larger LDL particles (LDL-1), and an inverse correlation between FEV1% p…
Is Health-Related Quality of Life Associated with Upper and Lower Airway Inflammation in Asthmatics?
2013
Background.Allergic diseases impair health-related quality of life (HR-QoL). However, the relationship between airway inflammation and HR-QoL in patients with asthma and rhinitis has not been fully investigated. We explored whether the inflammation of upper and lower airways is associated with HR-QoL.Methods.Twenty-two mild allergic asthmatics with concomitant rhinitis (10 males, 38 ± 17 years) were recruited. The Rhinasthma was used to identify HR-QoL, and the Asthma Control Test (ACT) was used to assess asthma control. Subjects underwent lung function and exhaled nitric oxide (eNO) test, collection of exhaled breath condensate (EBC), and nasal wash.Results.The Rhinasthma Global Summary sc…
Determinants of physical activity in daily life in candidates for lung transplantation
2012
BACKGROUND: Participation in daily physical activity (PA) has never been objectively assessed in candidates for lung transplantation (LTx). The main research questions were: 1) How active are LTx-candidates in daily life? 2) What are determinants of activity behavior before LTX? METHODS: Ninety-six candidates for LTx (diagnosis of COPD or interstitial lung disease; mean age 55 ± 7 years) underwent measurements of PA, pulmonary function, 6-min walking distance (6MWD), muscle force and health-status (SF-36 scale). RESULTS: Patients were markedly inactive (5% of waking hours walking, 26% standing and 69% sedentary). Backward multiple regression identified 6MWD (expressed as % of predicted valu…

Diesel motor emissions and lung cancer mortality--results of the second follow-up of a cohort study in potash miners.
2009
International health authorities have graded diesel motor emissions (DME) as probably cancerogenic in human beings. There are gaps in epidemiological evidence regarding exact exposure quantification, confounder control and the investigation of highly exposed populations. We investigated the association of DME ana lung cancer mortality in a historical cohort study of 5,862 German potash miners who were followed from 1970 to 2001. Cumulative exposure (CE) was measured by representative concentrations of total carbon multiplied with exposure years from the mines' medical records. Exposure and smoking behavior were validated by interviews of 3,087 participants. We computed standardized mortalit…
Physical capacity in performing daily activities is reduced in scleroderma patients with early lung involvement
2014
BACKGROUND: Patients with systemic sclerosis (SSc) often complain reduced capacity at submaximal exercise; conversely physical capacity in performing daily duties has never been measured in SSc. OBJECTIVES: To evaluate this performance and its correlates, in patients with SSc compared to healthy controls, in a free-living setting. METHODS: Twenty-seven outpatients with stable SSc and 11 controls were recruited. Physical activity was assessed by portable multiple sensor device (SenseWear Armband) worn for at least six days. Physical activity duration (PAD; in minutes) for non-sedentary activities and physical activity level (PAL= total daily energy/resting energy expenditure) per day were ca…
Force-, EMG-, and elasticity-velocity relationships at submaximal, maximal and supramaximal running speeds in sprinters.
1986
The relationships between ground reaction forces, electromyographic activity (EMG), elasticity and running velocity were investigated at five speeds from submaximal to supramaximal levels in 11 male and 8 female sprinters. Supramaximal running was performed by a towing system. Reaction forces were measured on a force platform. EMGs were recorded telemetrically with surface electrodes from the vastus lateralis and gastrocnemius muscles, and elasticity of the contact leg was evaluated with spring constant values measured by film analysis. Data showed increases in most of the parameters studied with increasing running speed. At supramaximal velocity (10.36 +/- 0.31 m X s-1; 108.4 +/- 3.8%) the…

Diffusion capacity of the lung in young and old endurance athletes
2013
Lung diffusion capacity (D LCO) declines with age. A significant proportion of older endurance athletes develop exercise-induced hypoxemia (SaO2<95%). We hypothesised that master endurance athletes have a lower D LCO than age-matched non-athletes. We recruited 33 control (16 young; 17 old) and 29 male endurance athletes (13 young; 16 old) during the World Masters Athletics Indoor Championships, 2012 (Jyvaskyla, Finland). To measure D LCO the participant exhaled to residual volume and then quickly inhaled to ≥ 90% total lung capacity from a gas source with 0.3% carbon monoxide. The D LCO and transfer coefficient (K CO) were corrected for the actual haemoglobin concentration. Spirometric func…
Survey of autoantibody responses against tumor-associated antigens in thyroid cancer
2014
Background Autoantibodies against tumor-associated antigens (TAAs) have been shown to serve as highly specific serological biomarkers for the diagnosis of various solid cancers. Although the autoimmunity against thyroid tissue specific antigens has been studied extensively, so far, the autoantibody responses against common TAAs such as cancer-testis antigens (CTAs), mutated or differentiation antigens have not been comprehensively analyzed in patients with thyroid cancer. Objective The current study aims to characterize the frequency of autoantibody responses against common TAAs in patients with thyroid cancer and benign thyroid nodules. Methods A phage-displayed antigen microarray comprisi…
