A different pattern of risk factors for atopic and non-atopic wheezing in 9-12-year-old children
2005
Few epidemiological studies have compared the risk factors of asthma or wheezing between atopic and non-atopic children. The objective of this study was to determine if there are specific risk factors for current wheezing related to atopic status in schoolchildren. Schoolchildren 9-12 yr of age from three Spanish cities (n = 2720) were subject to a cross-sectional study of asthma risk factors (by questionnaire) and atopy (by skin prick test) according to the ISAAC phase-II protocol. Risk factors for current wheezing (in the last 12 months) as reported by parents were investigated among the atopic (positive prick test to at least one allergen) and the non-atopic (negative prick test) childre…
An Urbanistic Project Based on General Systems Theory
1991
This paper intends to be an outline of the Urbanistic Development Planning of the Valencian Community in Spain to be performed during the years 1991 to 1993, The following are considered as objectives of the Planning: – Quality of Life improvement, – protection of Nature, – rational management of natural resources, – rational use of land; all based on social demand. The territory and the mechanism of intervention is considered as a system whose elements can be grouped as: – uses of land, – infrastructure, equipment, services, – objectives, – intervention and management. The Planning proposes itself to be: integral, strategic, prospective, programmed, controllable and participative, A simula…
Distribution of Intraocular Pressure and Its Association with Ocular Features and Cardiovascular Risk Factors
2013
Purpose To describe the distribution of intraocular pressure (IOP) and its association with ocular features and cardiovascular risk factors in an adult European cohort. Design Population-based, cross-sectional study. Participants This analysis was based on a Gutenberg Health Study (GHS) cohort that included 4335 eligible enrollees from among 5000 subjects who participated in the survey from 2007 through 2008. The age range was 35 to 74 years at enrollment. Methods Participants underwent a standardized protocol with a comprehensive questionnaire; ophthalmic examination including slit-lamp biomicroscopy, noncontact tonometry, fundus photography, central corneal thickness measurement, and visu…
Post-Migratory Employment Prospects: Evidence from Finland
2000
This paper analyses the role which migration plays in improving post-migratory employment prospects of migrants (long-distance) within Finland, by examining the employment status of migrants and non-migrants at the end of the migration interval. The analysis is based on micro data from the period 1985–90. The results from multivariate analyses suggest that migration by itself has not augmented the likelihood of getting a job, even though tabular comparisons of re-employment rates between migrants and non-migrants suggest this to be the case. Migration, however, has an indirect role in enhancing job search outcomes as it moves workers to labour markets characterized by more favourable employ…
Laparoscopic distal pancreatectomy: what factors are related to the learning curve?
2014
none 7 no PURPOSE: The factors related to the learning curve for laparoscopic distal pancreatectomy have rarely been evaluated. METHODS: A retrospective study of 32 patients who underwent a laparoscopic distal pancreatectomy performed at a high-volume center by a single pancreatic surgeon experienced with laparoscopic surgery was conducted. Pre-, intra- and postoperative data were collected. The primary endpoint was the length of the operation. The secondary endpoints were the conversion and reoperation rates, overall postoperative morbidity and mortality rates, the length of hospital stay and rate of unplanned splenectomy. RESULTS: The length of the operation and the cumulative sum of the …
Differential expression levels of urokinase-type plasminogen activator and cathepsin D in locally advanced laryngeal squamous cell carcinoma: Clinica…
2002
The expression levels and the prognostic impact of urokinase-type plasminogen activator (uPA) and cathepsin D (CD) were evaluated in patients with locally advanced laryngeal squamous cell carcinoma (LSCC). uPA and CD protein levels were determined by immunoluminometric or immunoenzymatic assays in the cytosol of paired sets of tumor tissues and corresponding adjacent normal mucosa (NLM) from 57 patients with stage III/IV LSCC and were correlated with a number of clinicobiological parameters of this tumor including anatomical site, tumor grade, nodal status, clinical stage, DNA ploidy, proliferation rate, and patient outcome. Median uPA levels were significantly higher in LSCC than in NLM (…
Visceral adiposity in patients with psoriatic arthritis and psoriasis alone and its relationship with metabolic and cardiovascular risk
2020
Abstract Background Fat mass distribution, especially in the abdominal visceral region, has been rarely evaluated in patients with PsA or psoriasis (PsO). Methods Patients with PsA and patients with PsO alone were evaluated and compared with control subjects (1:1 ratio in each patient group) matched for age, sex and BMI category. Body composition and fat distribution (android and visceral fat) were evaluated by DXA. Anthropometric measurements, disease activity and the systematic coronary risk evaluation (SCORE) cardiovascular risk were assessed. Metabolic parameters (insulin, homeostasis model assessment for insulin resistance), serum adipokines [total and high-molecular-weight adiponectin…
Molecular dynamics, dynamic site mapping, and highthroughput virtual screening on leptin and the Ob receptor as anti-obesity target.
2014
Body weight control is a mechanism finely regulated by several hormonal, metabolic, and nervous pathways. The leptin receptor (Ob-R) is crucial for energy homeostasis and regulation of food uptake. Leptin is a 16 kDa hormone that is mainly secreted by fat cells into the bloodstream, and under normal circumstances, circulating levels are proportionate to the fat body mass. Sensing of elevated leptin levels by the hypothalamic neurocircutry activates a negative feedback loop resulting in reduced food intake and increased energy expenditure. Decreased concentrations lead to opposite effects. Therefore rational design of leptin agonists constitute an appealing challenge in the battle against ob…
Intercultural Listening: Measuring Listening Concepts with the LCI-R
2016
Listening is an integral part of communication, yet more research is conducted on the speaker as opposed to the listener. Previous research established a general schema of listening as a concept-driven behavior with four factors (Imhof & Janusik, 2006). Further testing by Bodie (2010) confirmed the factor structure and reduced the number of items from 33 to 15 (LCI-R). What is not known is whether the constructs are consistent across cultures. This study investigates whether the LCI-R can fit independent data comprising samples from the United States, Europe, and Japan. Results show that the instrument can be used cross-culturally when listening concepts are of interest and need to be measu…
Beliefs and attitudes among Swedish workers regarding the risk of hearing loss
2004
The aim of this study was to develop an abridged version of the Tinnitus Questionnaire (TQ) to be used as a quick tool for the assessment of tinnitus-related psychological distress. Data from 351 inpatients and 122 outpatients with chronic tinnitus were used to analyse item statistics and psychometric properties. Twelve items with an optimal combination of high item-total correlations, reliability and sensitivity in assessing changes were selected for the Mini-TQ. Correlation with the full TQ was >0.90, and test-retest reliability was 0.89. Validity was confirmed by associations with general psychological symptom patterns. Treatment effects indicated by the Mini-TQ were slightly greater tha…
