Studies have showed that lead was associated with human health. However, the effects of lead on thyroid functions are inconsistent, and studies based on Chinese population are fragmentary. To evaluate the correlation between lead and thyroid functions of Chinese with different thyroid diseases, we conducted a hospital-based study. Ninety-six papillary thyroid carcinoma (PTC), 10 nodular goiter (NG), and 7 thyroid adenoma (TA) patients were recruited from the First Affiliated Hospital of Wenzhou Medical University, China...

BACKGROUND: This study investigated the association between pesticide exposure in Brazil (2005-2013) with rates of central nervous system (CNS) and cardiovascular system (CVS) congenital abnormalities in 2014. METHOD: An exposure variable was established from data on production and sales of pesticides (kg) per crop area (ha) for 2012 and 2013 years. The Brazilian states were divided into three categories: high, medium, and low pesticide use and rate ratios were estimated for each group of states (CI: 95 %)...

Latrine cleanliness increased in the intervention group compared to the control group (increase from 21 to 31 % of latrines classified as clean in intervention [N = 198] and decrease from 37 to 27 % in control [N = 91]). Improved habitual latrine cleaning lead to latrines being 3.5 times more likely to improve in observed latrine cleanliness (χ(2) = 16.36, p < .001) and so did improvements in quality of latrine construction, eg households that had installed a lid were 7.39 times more likely to have a cleaner latrine (χ(2) = 4...

Ensuring hygiene and health protection is one of the basic construction requirements. Such requirements are examined when commissioning new constructions and examining defects in constructions already in use. One substantial defect is biocorrosion which represents a synergistic process with a complex variety of factors. It is caused by biochemical manifestations of various micro-organisms (micromycetes). Micromycetes producing mycotoxins therefore play an important role regarding the so-called 'Sick Building Syndrome' that has become a global problem nowadays...

To assess the importance of malaria risk factors for children in sub-Saharan African countries. 61,292 children of 16 countries from DHS and MIS surveys were included in analysis. A regression model with analyse of variance and plots of mean decrease accuracy and mean decrease Gini indices were performed. The most important risk factor was the country and it contributed 52.33 % to the variance of the model. Wealth status of the child's family was the first socio-economic factor which contributed more to the difference of malaria risk among African children...

Unlike most quantitative studies that investigate decision-making on investing in sanitation, this study adopted a qualitative approach to investigate decision-making on shared sanitation in the informal settlements of Kisumu city, in Kenya. Using a grounded theory approach, landlords and tenants were interviewed to identify sanitation decisions, individuals involved in decision-making and factors influencing decision-making. The results indicate that the main sanitation decisions are on investment, emptying, repair and cleaning...

Previously, we reported the development of a Hazard Prediction and Assessment Capability plume dispersion model of the 2005 Graniteville, South Carolina, USA accidental release of chlorine. Here, we assess this model by spatial and statistical comparison with post-incident observed environmental indicators of exposure and other types of observations. Spatial agreement was found when the model was compared to phytotoxic bleaching and corrosion events observed in 2 km radius around the release site. When spatially compared to locations of injured or killed animals, model predictions of the plume footprint were in relatively good agreement...

The microbiological quality of bathing water and the surfaces of the surrounding pool platforms of two pools was estimated. ESBL- and MBL-producing Gram-negative bacteria isolated from water and surface samples were also studied. The water samples were satisfactory in 31 (86.1 %) out of 36 cases. Pseudomonas aeruginosa as well as Escherichia coli were identified in only 2 (5.5 %) cases. There were no correlations between the HPC and number of enterobacteria in the pool water and those found in the surface samples...

We aimed to develop a relevant multi-endpoint biomonitoring system by studying different genotoxicity biomarkers in complex carcinogenic exposures under occupational situations. Altogether 109 workers were followed in five different workplaces. The combined carcinogenic exposures were monitored in the urine and peripheral blood samples using Ames mutagenicity test and cytogenetic analyzes. The different genotoxicity endpoints studied showed different results in the same carcinogenic exposure situations. The urinary mutagenicity tests provided more information and proved to be more sensitive compared to the cytogenetic tests in the majority of cases...

Parabens are widely used as antimicrobial preservatives in cosmetics, pharmaceuticals, food and beverage processing due to their board spectrum of activity, inertness, and low cost. The study population consisted of 156 men under 45 years of age who attended the infertility clinic for diagnostic purposes with normal semen concentration of 15-300 mln/ml. Participants were interviewed and provided a semen sample. The parabens concentrations: ethyl paraben (EP), butyl paraben (BP), methyl paraben (MP), and iso-butyl paraben (iBuP) were analyzed in the urine using a validated gas chromatography ion-tap mass spectrometry method...

Diarrhoea still remains an unsolved enigma in developing countries, a major concern for the health planners. We targeted the abundance and toxicity of Vibrio cholerae non-O1/non-O139 (NOVC) in Gangetic riverine-estuarine ecosystem. A total of 74 V. cholerae were isolated from 120 water samples (68 NOVC, 6 V. cholerae O1) from two sampling sites off river Ganges. V. cholerae showed distinct seasonality, with steady increase from summer to monsoon, steep ascent in post-monsoon and an abrupt decline in winter...

Polybrominated diphenyl ethers (PBDEs) are commonly used flame retardants in foams, building material, electronics, and textiles. These chemicals leach into the environment, where they persist, and are found today in virtually every population worldwide. Several studies in recent years have detected the presence of PBDEs in maternal and infant samples. However, few of these studies were conducted in the U.S., and few examined paired or matched mother blood-cord blood samples. We analyzed serum from 10 mother-infant pairs for the presence of PBDEs in a patient population in the Southeastern U...

We surveyed the opinions of Finnish food business operators (FBOs) about the uniformity of local official food control and its importance for dairy, fishery and meat plants. A total of 136 FBOs responded to the questionnaire. Most FBOs considered official food control to be important for food safety and were generally satisfied with its quality. However, they often did not perceive official food control as being uniform, and 23% even considered it arbitrary. Small-sized FBOs were particularly critical of the relevance of control actions...

Several epidemiological studies have found some evidence suggesting that exposure to air pollutants during pregnancy increases the risk of adverse birth outcomes. In this cohort study, we assessed individual maternal exposure to nitrogen dioxide (NO2) during pregnancy and examined the association between the exposure and pregnancy outcomes, such as low birth weight (LBW), term low birth weight (TLBW), small for gestational age (SGA) and preterm birth (PB). 3292 women living in Kaunas city, Lithuania, data and their singleton newborns were included in the study...

Relationship between cooking fuel and under-five mortality has not been adequately established in Sub-Saharan Africa (SSA). We therefore investigated the association between cooking fuel and risk of under-five mortality in SSA, and further investigated its interaction with smoking. Using the most recent Demographic Health Survey data of 23 SSA countries (n = 783,691), Cox proportional hazard was employed to determine the association between cooking fuel and risk of under-five deaths. The adjusted hazard ratios were 1...

The purpose of the present study was to investigate the prevalence and molecular characterization of Giardia duodenalis among dogs in Aydin, Turkey. A total of 473 faecal samples from dogs were collected. The overall prevalence of G. duodenalis was 18.8%. Higher infection rates were observed in dogs younger than three months old, from shelters, and with diarrhoea. Faecal samples of 89 dogs, diagnosed Giardia-positive by microscopy, were found positive by nested PCR. The β-giardin nested PCR assay revealed assemblage B in all samples (100%), whereas 38 of the samples were mixed with assemblage A (42%)...
