..abstract:..

..We conducted a pilot study on early-life arsenic exposure and long-term lung function. We present these preliminary findings because of the magnitude of the effects observed...

..The Chilean experience in removal of arsenic suggests that it is feasible to reach this level using the conventional coagulation process...

..A home-based self-collected vaginal sampling was nested in the 2003 Chilean population-based health survey in order to explore the possibility of a type-specific geographical variation for human papillomavirus..

..More than 18 types of human papillomavirus (HPV) are associated with cervical cancer, the relative importance of the HPV types may vary in different populations...

..Overall, we conclude that highly accurate screening for cervical cancer and CIN 3 is now technically feasible. The remaining vital issue is to extend improved cervical cancer prevention programs to resource-poor regions...

..Cervical cancer is the third cause of cancer death among Chilean women, affecting mainly women from low socioeconomic status...

..Aim To estimate the main factors associated with smoking initiation and quitting among a cohort of adult women living in a low socioeconomic status area of Santiago, Chile...

..To validate a non-invasive method to detect gastric mucosal atrophy in a Chilean population with high prevalence of gastric cancer and a poor survival rate...

..We tested whether cholesterol gallstone disease (GS) is associated to insulin resistance and serum C-reactive protein (CRP) in a high risk population...

..There are several diagnostic criteria for Metabolic Syndrome (MS) definition...

..To study the incidence and survival rate of stomach cancer (SC) and its associated factors in a high risk population in Chile...

..This history provides a unique opportunity to study time trends in the development of arsenic-related cancers, including lung and bladder cancers...

..Unit non-response is a growing problem in sample surveys that can bias survey estimates if respondents and non-respondents differ systematically...

..7). Our results suggest that gallbladder cancer in Chile may be related to both genetic factors and poor living conditions. Future analytic studies are needed to further clarify the role of these factors in gallbladder cancer etiology...

..Smoking increases the risk of squamous-cell carcinoma of the cervix, but it is not clear whether smoking increases the risk of acquisition or persistence of human papillomavirus (HPV) infection...

..With these three causes of death combined, increased mortality peaked in 1991-1995, with estimated excess deaths related to arsenic exposure constituting 10.9% of all deaths among men and 4.0% among women...

..Limited evidence suggests that arsenic may have adverse human reproductive effects. We investigated the association between drinking water arsenic exposure and fetal growth, as manifest in birth weight...

..Key words: arsenic, arsenic metabolism, arsenic methylation, Chile, pregnancy, urinary arsenic...

..Our study showed an effect of both women's and their husbands' sexual behavior on HPV positivity. Furthermore, it suggests some differences in the pattern of the association between sexual behavior and different HPV types...

....

..These differences, however, underline that great caution should be used in inferring the natural history of HPV from age-specific prevalences...

....

..This study was designed to compare chromosomal alterations in bladder cancers of arsenic-exposed individuals to provide insight into the mechanism of how arsenic may induce or promote cancer...

..We ascertained the follow-up care after an abnormal cytology (Papanicolaou) screening in the San Marti;n region of Perú and assessed the status of women who had not received adequate care...

..Arsenic exposure was not associated with an increased prevalence of p53 mutation or P53 immunopositivity and there was no evidence of interaction between arsenic and smoking with these outcome variables...

..VIA gives immediate results, but will require investment in regular training and supervision. Further work is needed to determine whether screened-positive women should all be treated or triaged with a more specific test...
