Congenital anomalies among live births in a high environmental risk area—A case-control study in Brindisi (southern Italy)
2013
Maternal exposure to ambient pollution has been increasingly linked to the risk of congenital anomalies (CAs) in the fetus and newborns. Recently, a descriptive study in the high environmental risk city of Brindisi (Italy) revealed an increased prevalence of total CAs, especially congenital heart disease (CHD) and ventricular septal defects (VSDs), both at the local level and in comparison with the pool of EUROCAT registries. This paper concerns a population-based case control study to investigate the association between maternal exposure to air pollutants - sulfur dioxide (SO2) and total suspended particulate (TSP) matter - and the risk of CA. Cases were newborns up to 28 days of age, born…
Treated Incidence of Psychotic Disorders in the Multinational EU-GEI Study
2018
Importance: Psychotic disorders contribute significantly to the global disease burden, yet the latest international incidence study of psychotic disorders was conducted in the 1980s. Objectives: To estimate the incidence of psychotic disorders using comparable methods across 17 catchment areas in 6 countries and to examine the variance between catchment areas by putative environmental risk factors. Design, Setting, and Participants: An international multisite incidence study (the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions) was conducted from May 1, 2010, to April 1, 2015, among 2774 individuals from England (2 catchment areas), France (3 catch…
Penalized linear discriminant analysis and Discrete AdaBoost to distinguish human hair metal profiles: The case of adolescents residing near Mt. Etna
2016
The research focus of the present paper was twofold. First, we tried to document that human intake of trace elements is influenced by geological factors of the place of residence. Second, we showed that the elemental composition of human hair is a useful screening tool for assessing people's exposure to potentially toxic substances. For this purpose, we used samples of human hair from adolescents and applied two robust statistical approaches. Samples from two distinct geological and environmental sites were collected: the first one was characterized by the presence of the active volcano Mt. Etna (ETNA group) and the second one lithologically made up of sedimentary rocks (SIC group). Chemica…
Personal and Environmental Risk Factors at Birth and Hospital Admission: Direct and Vitamin D-Mediated Effects on Bronchiolitis Hospitalization in It…
2021
Seasonal variations in UV-B radiation may influence vitamin D status, and this, in turn, may influence the risk of bronchiolitis hospitalization. The aim of this study was using a causal inference approach to investigate, simultaneously, the interrelationships between personal and environmental risk factors at birth/hospital admission (RFBH), serum vitamin D levels and bronchiolitis hospitalization. A total of 63 children (<
First results of a European multi-center registry of patients with anorectal malformations.
2013
Background: The European consortium on anorectal malformations (ARM-NET) was established to improve the health care of patients and to identify genetic and environmental risk factors. The aim of the present study was to present the first results on clinical data of a large European cohort of ARM patients based on our registry. Methods: In 2010, the registry was established including patient characteristics and data on diagnosis, surgical therapy, and outcome regarding complications. Patients born between 2007 and 2012 were retrospectively added. A descriptive analysis of this cohort was performed. Results: Two hundred and three ARM patients were included. Syndromes or chromosomal abnormalit…
Multiple stressors in Mediterranean coastal wetland ecosystems : Influence of salinity and an insecticide on zooplankton communities under different …
2021
Temperature increase, salinity intrusion and pesticide pollution have been suggested to be among the main stressors affecting the biodiversity of coastal wetland ecosystems. Here we assessed the single and combined effects of these stressors on zooplankton communities collected from a Mediterranean coastal lagoon. An indoor microcosm experiment was designed with temperature variation (20 °C and 30 °C), salinity (no addition, 2.5 g/L NaCl) and the insecticide chlorpyrifos (no addition, 1 μg/L) as treatments. The impact of these stressors was evaluated on water quality variables and on the zooplankton comunity (structure, diversity, abundance and taxa responses) for 28 days. This study shows …
Characterization of chronic obstructive pulmonary disease in dairy farmers
2020
International audience; Background - Although farming is often considered a risk factor for COPD, data regarding the burden and characteristics of COPD in dairy farmers are sparse and conflicting. Objectives - To characterize COPD in dairy farmers. Methods - 4788 subjects entered two parallel COPD screening programs, one in agricultural workers and one in general practice from 2011 to 2015. Subjects with COPD were invited to participate in the characterization phase of the study. Those who accepted were included in two subgroups: dairy farmers with COPD (DF-COPD) (n = 101) and non-farmers with COPD (NF-COPD) (n = 85). Patients with COPD were frequency-matched with subjects with normal spiro…
Preliminary report of a multicentric study on environmental risk factors in Ta-T1 transitional cell carcinoma of the bladder
2006
<i>Objective:</i> The distribution of potential environmental risk factors among patients affected by superficial transitional cell carcinoma of the bladder (TCCB) has been analyzed. <i>Methods:</i> Patients affected by superficial TCCB underwent TUR and early intravesical chemotherapy. Detailed data about age, sex, residence, employment, active and passive cigarette smoking, water resource and hair dye use were centralized. Analysis has been conducted on 474 patients affected by Ta-T1 G1-2 TCCB at medium risk for recurrence. Patients with primary single Ta G1-2, Tis or T1G3 tumors were excluded from the present analysis. <i>Results:</i> Over 80% of the p…
Methodological Problems in RCTs on IBD
2012
Abstract: Randomized controlled trials (RCTs) are the gold standard method for developing evidence-based medicine in inflammatory bowel disease (IBD). Methodological problems in RCTs in IBD concern different aspects such as the definition of the study population due to the extreme variability of patients with IBD, the indices of disease activity, a clearly defined outcome, the environmental risk factors (i.e smoking behaviour) that may influence the randomization, the heterogeneous placebo rate of remission and the different statistical methods used to analyze the results. It is important that trials are designed efficiently, done well and complement clinical practice with a careful subject…
Environmental Risk Factors in Superficial Bladder Cancer
2004
As a preliminary approach to define the object of larger case-control studies, the distribution of potential risk factors coming from environmental pollution among patients affected by superficial bladder cancer (TCCB) has been analyzed. Material e Methods. The analysis included only patients affected by medium risk superficial TCCB. Forty Italian urological centres joined the study. Detailed information about age, sex, residency, employment, active and passive cigarette smoking, water resource, hair-dye use were centralized. All patients underwent TUR and early intravesical chemotherapy. The distribution of the above mentioned environmental factors was related to tumor characteristics suc…
