One simple claudication question as first step in Peripheral Arterial Disease (PAD) screening: A meta-analysis of the association with reduced Ankle …
2019
Purpose and methods A meta-analysis using data from seven German population-based cohorts was performed by the German Epidemiological consortium of Peripheral Arterial Disease (GEPArD) to investigate whether one question about claudication is more efficient for PAD screening than established questionnaires. Claudication was defined on the basis of the answer to one question asking for pain in the leg during normal walking. This simple question was compared with established questionnaires, including the Edinburgh questionnaire. The associations of claudication with continuous ABI values and decreased ABI were analyzed by linear and logistic regression analysis, respectively. The results of t…
Low bone mineral density in HIV-positive young Italians and migrants.
2020
Background Human immunodeficiency virus (HIV) infected individuals may have osteoporosis. We aimed to evaluate the bone mineral density (BMD) in naïve antiretroviral (ARV) treated HIV positive patients comparing native Italian group (ItG) to a Migrants group (MiG) upon arrival in Italy. Methods We conducted a cross-sectional study on 83 HIV patients less than 50 years old. We used the dual-energy X-ray absorptiometry (DXA) within six months from the HIV diagnosis. Participants were categorized as having low BMD if the femoral neck or total lumbar spine Z-score was– 2 or less. Results MiG showed low BMD more often than ItG (37.5% vs.13.6%), especially for the female gender (16.7% vs. 0.0%). …
Reversal of Hartmann's procedure: a single-centre experience of 533 consecutive cases.
2018
AIM Hartmann's procedure (HP) is common. However, restoration of intestinal continuity is not so frequent. The aim of this study was to determine predictive factors which might influence outcomes following the reversal of HP. METHOD All consecutive patients who underwent elective and emergency HP in a single institution between January 1999 and December 2014 were included. Data concerning patient, disease and treatment features were collected. Univariate and multivariate binary logistic regression models were used to determine prognostic factors. RESULTS A total of 533 consecutive patients underwent HP over the 16-year period. Factors that were associated with a higher probability of revers…
Playing tactics, contextual variables and offensive effectiveness in English Premier League soccer matches. A multilevel analysis.
2020
The aim of this study was to investigate the combined effects of tactical and contextual indicators on achieving offensive penetration and scoring opportunities in English Premier League (EPL) soccer matches. A total of 1971 team possessions from 20 random matches were evaluated by means of multidimensional observation. The EPL matches had a great proportion of fast attacks (36.0%) followed by combinative (29.6%), direct attacks (24.1%) and counterattacks (9.5%). Multilevel logistic regression models revealed that counterattacks (OR = 3.428; 95% CI: 2.004–5.864; P<0.001) were more effective to create goal scoring opportunities than combinative attacks, while direct attacks showed to be less…
Urban green and grey space in relation to respiratory health in children
2017
We assessed the effect of three different indices of urban built environment on allergic and respiratory conditions.This study involved 2472 children participating in the ongoing INMA birth cohort located in two bio-geographic regions (Euro-Siberian and Mediterranean) in Spain. Residential surrounding built environment was characterised as 1) residential surrounding greenness based on satellite-derived normalised difference vegetation index (NDVI), 2) residential proximity to green spaces and 3) residential surrounding greyness based on urban land use patterns. Information on wheezing, bronchitis, asthma and allergic rhinitis up to age 4 years was obtained from parent-completed questionnair…
Fat intake in children with autism spectrum disorder in the Mediterranean region (Valencia, Spain)
2015
Children with autism spectrum disorder (ASD) have been found to have alterations in dietary fat intake and fat quality. The fat intakes of the foods consumed by children with and without ASD were compared, and the deficiency and excess of these nutrients were examined.In a matched case-control study, 3-day food diaries were completed by 105 children with ASD and 495 typically developing (TD) 6- to 9-year-old children in Valencia (Spain). We used the probabilistic approach and estimated average requirement cut-point to evaluate the risk of inadequate nutrients intakes. These were compared between groups and with Spanish recommendations using linear and logistic regression, respectively.Group…
Psychotic experiences and subjective cognitive complaints among 224 842 people in 48 low- and middle-income countries.
2018
Abstract Aims Cognitive deficits are an important factor in the pathogenesis of psychosis. Subjective cognitive complaints (SCCs) are often considered to be a precursor of objective cognitive deficits, but there are no studies specifically on SCC and psychotic experiences (PE). Thus, we assessed the association between SCC and PE using data from 48 low- and middle-income countries. Methods Community-based cross-sectional data of the World Health Survey were analysed. Two questions on subjective memory and learning complaints in the past 30 days were used to create a SCC scale ranging from 0 to 10 with higher scores representing more severe SCC. The Composite International Diagnostic Intervi…
The Role of the Unitary Prevention Delegates in the Participative Management of Occupational Risk Prevention and Its Impact on Occupational Accidents…
2020
The aim of this research was to study the impact of the unitary prevention delegates (UPDs) on the Spanish working environment. To this end, a cross-sectional study was carried out using microdata from the National Survey on Health and Safety Management in Companies (ENGE-2009) with a sample of 5147 work centres. To measure the relationship between the presence of UPD in workplaces with preventive management indicators and damage to health, individual and multiple logistic regression models were carried out, calculating the crude (cOR) and adjusted (aOR) odds ratios by sociodemographic covariates, with their corresponding 95% confidence intervals (95% CI). Ambivalent results were obtained. …

Academic well-being and smoking among 14- to 17-year-old schoolchildren in six European cities
2016
It is well established that poor academic performance is related to smoking, but the association between academic well-being and smoking is less known. We measured academic well-being by school burnout and schoolwork engagement and studied their associations with smoking among 14- to 17-year-old schoolchildren in Belgium, Germany, Finland, Italy, the Netherlands, and Portugal. A classroom survey (2013 SILNE survey, N = 11,015) was conducted using the Short School Burnout Inventory and the Schoolwork Engagement Inventory. Logistic regression, generalized linear mixed models, and ANOVA were used. Low schoolwork engagement and high school burnout increased the odds for daily smoking in all cou…
