..The main goal of the present analysis was to assess the possible impact of coexposure to PAH-containing barbecued meat consumed during pregnancy on birth outcomes...

..37, 95% CI: 0.15-0.91). No other fruit was significantly associated with altering the risk of colorectal cancer...

..To determine whether the cognitive deficit documented in this study persists to older ages, the follow-up of the children over the next several years is to be carried out...

..The data support the hypothesis that burden of respiratory symptoms in early childhood and possibly in later life may be programmed already in prenatal period when the respiratory system is completing its growth and maturation...

..The study also provided evidence that male fetuses are more sensitive to prenatal PM(2.5) exposure and this should persuade policy makers to consider birth outcomes by gender separately while setting air pollution guidelines...

..The primary purpose of the study was to establish a possible association between very low levels of prenatal exposure to lead and mental development of children at 12, 24 and 36 months of age...

..Current epidemiologic studies investigating the effect of fish intake on colorectal cancer (CRC) risk are scarce. Therefore, the aim of this study was to elucidate the relationship between fish consumption and CRC risk...

..This study assessed personal exposure of pregnant women to fine particles (PM(25)) and benzo[a]pyrene (B[a]P) and the relationship between pollutant concentrations in ambient and indoor air...

..The cohort study in Krakow provided an opportunity for comparative assessment of fetal exposure to SHS based upon questionnaires and cord blood cotinine measurements...

..5) resulting in an increased burden of respiratory infections among infants...

..67 microg/dl) was relatively high (89%) its positive predictive value was too low (22%), so that the screening program based on the chosen cord blood lead criterion was recommended...

..The observed protective effect of apple consumption on colorectal risk may result from their rich content of flavonoid and other polyphenols, which can inhibit cancer onset and cell proliferation...

..Observed cognitive deficit in early wheezers may be caused by RSV infections or can be related to lower lung function attributed to persistent wheezing, which reducing oxygen supply would affect rapidly developing brain...

..The objective of this study was to assess a hypothesized beneficial effect of fish consumption during the last trimester of pregnancy on adverse birth outcomes resulting from prenatal exposure to fine air particulate matter...

..9; 95% CI: 2.2-3.9) but also overweight in early childhood (RR=2.7; 95% CI: 1.7-4.4). The conclusion is that excessive GWG may be a risk factor for overweight in early childhood and should be a focus of public health policy...

..Several in vivo and in vitro studies have shown that metal-rich particles may enhance allergic responses to house dust mites and induce an increased release of allergy-related cytokines...

....

..The findings showed that significant lung function deficits in early childhood are associated with prenatal exposure to fine particulate matter, which may affect fetal lung growth...

..As we reported no synergistic effects between prenatal PAH (measured by PAH-DNA adducts) and PM(2.5) exposures on early wheeze, this suggests the two exposures may exert independent effects via different biological mechanism on wheeze...

....

..The purpose of this study was to estimate the amount of absorbed mercury (Hg) by mothers and their infants as a result of fish consumption during pregnancy...

..Although the maternal fish consumption is supposed to have beneficial effects on development of infants, it may be harmful for child cognitive development since fish is a common source of methylmercury...

....

..Auto emissions for example, are low in benzo(a)pyrene, whereas such emissions from refuse burning are high...

..56; 95% CI: 0.28-1.10). The protective effect of healthy nutrition appeared to be independent from that attributed to physical effort...

..The effect of allergen sensitization on lung size and airway caliber confined to symptomatic subjects may reflect the inflammatory status of bronchial airways in the symptomatic subjects...

..96 and that above 83 g/day by 2.20. In colorectal cancer, the significant protective effect of retinol, carotene and vitamin C has been evidenced, however, only carotene and vitamin E were inversely correlated with stomach cancer...

..The interesting feature of childhood asthma is the great reversibility of symptoms. The main purpose of this study was to assess the effect of persistent and reversed asthma-like symptoms on lung function growth in preadolescent children...

..The associations were mainly seen for particulates or sulfur dioxide, and thus they confirmed the findings from other parts of Europe and the United States...

....

..5% in the total sample, however, only 2.9% in non-allergic children, 7.2% in children in whom allergy was diagnosed by physicians and 8.5% among those children among whom allergy was diagnosed by allergic skin tests...

..We found the highest rates in the southeastern and northern part of the country and this was not compatible with the hygienic hypothesis of asthma and allergic diseases...

..The preliminary results demonstrated the protective effect of higher physical activity in the occurrence of colorectal cancer after accounting for nutritional habits...

..A hypothesis that vaccination with live attenuated measles virus performed in early childhood may prevent allergic sensitization has been explored in the course of a 3-year follow-up study in Kraków (Poland) among 1005 school children...

....

..The particular purpose of our study was to assess the impact of environmental tobacco smoke (ETS) on the individual variability of blood lead levels in pregnant women as earlier publications demonstrated the increased blood lead in smokers...

..The purpose of the study was to determine whether maternal use of antibiotics during pregnancy is a risk factor for wheezing and allergy in early infancy...

..When additional variables were included in the multivariate logistic models such as children health status and potential errors of medical diagnosis, estimated effectiveness of current vaccination program was higher than 90%...

..The risk of obstructive ventilation disorders (FEV1/FVC% 85) was significantly higher in children from the residential areas with higher air pollution (RR = 1.71; 95% CI: 1.19-2.47)...

..This study suggests that a lower level of lung function in pre-adolescent children can be related to postnatal exposure to indoor emissions in the winter...

..These results indicate the need to reduce ambient fine particulate concentrations. However, further research should establish possible biologic mechanisms explaining the observed relationship...

..The aim of the study is to assess the cognitive and psychomotor status of 1-year-old infants whose mothers were exposed to low, but varying, amounts of mercury during pregnancy...

..As the height gain is lower in exposed subjects and this does produce a height deficit, the estimates of adjusted lung function to body size may be biased...

..1, p = 0.00) but not with higher intakes (beta = -0.3, p = 0.56). Prepregnancy nutrition of mothers may modulate the harmful effects of prenatal exposures to pollutants on birth outcomes...
