Filter by:The purposes of this study are to determine the practicality of using home indoor air quality monitoring and a smartphone app to identify home air quality changes and how these changes affect adults with asthma.
Plastic products have been used ubiquitously in the modern world for many decades - for example as packaging materials, textile fibers or molded parts. The general use and especially the improper disposal lead to enormous environmental pollution almost everywhere on earth. Microplastics mainly originate from fragmentation of larger plastic objects or can be produced directly for the use in e.g. cosmetics or industrial dyes. Microplastics have already been detected in fresh- and seawater, soil, food, but also in human blood and urine. The accumulation of microplastics in ovarian and testicular tissue in humans has not yet been investigated.
The goal of this cluster-randomized trial in rural Guatemala is to assess intervention strategies to reduce plastic burning in 8 intervention villages compared to 8 control villages. The intervention group participants will participate in 12 weekly behavioral working group sessions; the control group will not receive any specific activities. Two hundred women of reproductive age as well as other community members from these villages will be enrolled in each group. The follow-up period is 12 months. A Community Advisory Board will be formed in order to provide input on study activities, evaluate working group intervention strategies, and discuss the potential to expand activities regionally. Data will be collected via interviews, focus groups, air pollution sampling, plastic waste collection, urinary biomarker assessments, and ambient air sampling. Program evaluation and results dissemination will occur in the last year of the project.
1. Purpose: To confirm the changes in lifestyle due to differences in perceptions of infectious disease risk after the COVID-19 pandemic, decrease in exposure levels of environmentally hazardous chemicals and changes in indicators related to chronic kidney disease 2. Methods: - Survey on health risk awareness and lifestyle for COVID-19 - Blood and urine tests for exposure to environmentally hazardous chemicals - Collection of hospital clinical data utilization for indicators related to chronic kidney disease 3. Clinical endpoints: - Verification of differences in health risk perception level and lifestyle changes - Verification of changes in lifestyle changes and exposure to environmentally hazardous chemicals - Verification of changes in indicators related to kidney disease according to changes in exposure to environmentally hazardous chemicals 4. Statistical methods: chi-square test, independent mean comparison t-test, ANOVA test, regression analysis
Investigators want to learn the role of indoor environmental exposures on respiratory symptoms, and, separately, on lung function deficits in school-aged children with bronchopulmonary dysplasia (BPD).
Tongji-Ezhou study (TJEZ) is a prospective cohort study launched at 2013 in EZhou city, Hubei province, with the goal of recruiting and assessing 10,000 individuals and then following them for at least 2 decades. In addition, blood samples would be collected every 3-5 years among 6000 of them to investigate the nutritional biomarkers and potential determinants of chronic diseases such as obesity, type 2 diabetes, metabolic syndrome, and cardiovascular disease.
the aim of this preliminary observational study is to compare external exposomes from 10 teeth issued through 10 subjects living in high incidence of crohn's disease area and 10 teeth issued through 10 subjects living in low incidence of crohn's disease area.
The study is a prospective cohort study, which is aiming to explore periconceptional phthalates exposure and its potential epigenetic effect on fertility, embryo development, and neonatal outcomes.
Introduction: Sarcomas are rare tumors of connective tissue. The exact overall incidence of sarcomas is unknown due to diagnostic difficulties and the various histological subtypes (over 80 subtypes). However, the apparent increasing incidence of sarcomas suggests environmental causes such as pesticides. Except for some specific factors (i.e. ionizing radiation, vinyl chloride, dioxin, and genetic predispositions) the scientific knowledge on the aetiology of sarcomas is sparse and inconsistent. France is a particularly appropriate country to set up a study investigating the causes of sarcoma occurrence due to the French organization in treatment and care of sarcoma patients, which is highly structured and revolved around national expert networks. The main objective of the ETIOSARC project is to study the role of lifestyle, environmental and occupational factors in the occurrence of sarcomas among adults from a multicentric population-based case-control study. Methods and analysis: Cases will be all incident cases (older than 18 years old) identified in 15 districts of France covered by a cancer registry and/or a reference center in sarcoma's patient care over a three-year period with an inclusion start date ranging from the 1st October 2018 to the 1st January 2020 and histologically confirmed by a second review of the diagnosis. Two controls will be individually-matched by sex, age (5-years group), and districts of residence and randomly selected from electoral list. A standardized questionnaire will be administered by a trained interviewer in order to gather information about occupational and residential history, demographic and socioeconomic characteristics and lifestyle factors. At the end of the interview, a saliva sample will be systematically proposed. This study will permit to validate or not already suspected risk factors for sarcomas such as phenoxyherbicides, chlorophenol and to generate new hypothesis to increase our understanding about the genetic and environmental contributions in the carcinogenicity process.
To reduce the risk of adverse health problems associated with chronic exposure to pesticides, a randomized control study will evaluate a nurse-led integrated pest management (IPM) intervention in 88 child care centers serving socio-economically and ethnically diverse preschool-age children in four California counties. Positive changes in IPM knowledge, policies, practices, pests, and pesticide exposure will be assessed.
