Filter by:This pilot study (n=20) is a prospective evaluation of the implementation of an indoor air pollution intervention among patients who have undergone recent percutaneous coronary intervention procedures. The intervention, called Air Improvement and Real-time Monitoring for Wellness through Interactive Strategies and Education (AIRWISE), is focused on improving indoor air quality through air filtration, education, and behavioral recommendations. All participants will receive the AIRWISE intervention with the objective of evaluating acceptance and use of the individual intervention components. This implementation study will inform the submission of a larger NIH proposal for a randomized trial. The central study hypothesis is that an intervention program with educational strategies and visual behavioral cues will increase knowledge and awareness of air pollution exposures among the participants and lead to improved intervention compliance.
Cystic fibrosis (CF) is the most common autosomal recessive disease that leads to early mortality in Caucasians and affects around 7500 patients in France. Progression of the disease depends on pulmonary exacerbations defined as acute deterioration of respiratory symptoms which ultimately impair lung function and quality of life. Most frequently caused by lung bacterial infections, exacerbations' effects include increased cough, increased sputum production, increased use of antibiotics, dyspnea and decreased lung function. The phenotypic variability of CF suggests the implication of other contributors especially to the CF airway disease. Beside genetic and epigenetic alterations, environmental factors - e.g tobacco smoke, air pollution, temperature changes, food intake - appear as relevant candidates. A previous review has discussed current knowledge on the effects of air pollution on the course of CF disease. Although scarce, the existing epidemiological andexperimental literature suggests a link between exposure to air pollutants and adverse health effects.Although scarce, the existing epidemiological and experimental literature suggests a link between exposure to air pollutants and adverse health effects. The EU sponsored REMEDIA project (Impact of exposome on the course of lung diseases, Grant agreement ID 874753) contributes to the understanding of the influence of the exposome on chronic obstructive pulmonary disease (COPD) and CF. Objective of work package 3 within the REMEDIA project is the development of a mobile environmental sensor toolbox that is capable to assess the external exposome. The biomarkertoolbox was developed and tested in a proof-of-concept study carried out in healthy volunteers. The next step is to validate the collectionof exhaled breath condensate (EBC) in a real-life study. In this aim, the objective of the present study will be to assess the feasibility of EBC collection in CF patients and healthy individuals
This is a cross-sectional study to evaluate the variation of biological biomarkers of oxidative stress and inflammation in response to the external exposome, in people with Multiple Sclerosis (pwMS).The objective is to study the variation of biological biomarkers of oxidative stress and inflammation in response to external exposome in pwMS, controlling for other biomarkers (cytokine, neurofilaments, microbiome), gender, age, anthropometric measurements, vitamin D levels and medical history. Specifically, the variation of microRNAs is defined as the primary outcome, in response to urban air pollution, urbanization, lifestyle and quality of life components of the external exposome. Following the functional exposome approach:(1)Information on a pwMS sample about socio-demographic characteristics and medical history will be collected and specific components of the (2) On the same pwMS sample, the internal exposome variation will be measured. MicroRNA levels and gut and nasal microbiota alpha- and beta-diversity and relative bacterial abundances will be considered as biomarkers of oxidative stress and inflammation. At the same time, cytokines and neurofilament proteins (NfL) will be measured as biomarkers of neurodegeneration and axonal damage. Adults (≥ 18 years) pwMS, with relapsing-remitting course, diagnosis of MS according to 2017 McDonald criteria and residing in Pavia or Milan (Italy) will be included. Potentially eligible pwMS will be screened by a neurologist expert in MS who will verify that all the inclusion criteria will be fulfilled. To validate variation among 7 selected MS diagnostic miRNA, in response to urban air pollution, urbanization, lifestyle and quality of life components of the external exposome, the differential expression (ΔCT) for each miRNA will be considered as the outcome measure. Two hundred eligible pwMS who meet the inclusion criteria and sign the informed consent will be included in the study, to consider 15% dropout at the blood sampling stage.
By reconstructing schoolyards with greenery, physical activity levels among children can be increased at the population level and also mitigate health and environmental risks resulting from rising climate changes in urban areas. The overarching purpose of the proposed project is to: i. increase physical activity levels among school-aged children, independent of socioeconomic factors, and thus affect short- and long-term health outcomes on a population level ii. establish an evidence-based bottom-up approach for schoolyard reconstructions iii. evaluate the cost-effectiveness of schoolyard reconstructions with greening on health outcomes and its environmental impact
The main objective is to identify specific risk factors for ANCA vasculitis of occupational and/or environmental origin (exposures identified by questioning, geographical distribution of cases) from the RNV3P data. The secondary objectives are as follows: - Description of cases of ANCA vasculitis seen in French occupational pathology consultation centres: - reasons for consultation, - occupational and environmental etiologies described - occupational situations responsible - aptitude notices - recognition as an occupational disease - Identification of specific risk factors for ANCA vasculitis of occupational and/or environmental origin (exposures identified on questioning, geographical distribution of cases). - For occupational and non-occupational cases of ANCA vasculitis: identification of difficulties encountered by patients at work and proposed work adaptations. - Estimation of the number of applications for recognition of disabled worker status made within this patient group. - Identification of clinical severity and autoimmune profiles of ANCA vasculitis of occupational and/or environmental origin.
Recent studies on health personnel in Colombia have evidenced the considerable increase in the levels of stress and anxiety, among other psychological disorders, as a product of the COVID-19 pandemic that is being experienced since 2019 and that implies a greater demand for attention from the affected citizens, with the consequent work overload and tension due to the risk of contagion. Thus, the present work will allow the generation of new knowledge in relation to the benefits of Vitamin N therapy in Colombia; which can contribute quickly and effectively to the reduction of stress levels, anxiety, insomnia, and depression in individuals, when compared with conventional interventions and result in possible benefits such as the reduction of health problems such as obesity, diabetes, high blood pressure, and diseases associated with the immune system.
To quantify health effects of synergizing chemical and biological pollutants in a targeted population setting, i.e., school-aged children. Indoor air pollutants will be monitored within the classrooms with high end sensors. Exposure data from additional sources (outdoor, home, transports) will be obtained. Health outcomes will be assessed prospectively using validated medical procedures and real-time tracking with mobile health (mHealth) equipment and a gamified computer app.
Exposure to adverse environments such as socioeconomic disadvantage and psychosocial deprivation are risk-factors for neurodevelopmental problems in childhood. Children exposed to such environments may benefit from interventions that target social-communication abilities, since these skills act as protective factors for healthy neurodevelopment in vulnerable children. One early childhood intervention that has shown efficacy in improving early social-communication development is Paediatric Autism Communication Therapy (PACT). However, there are no studies testing the efficacy of PACT in Latin American countries where environmental risk factors are common. This randomized controlled trial will test the efficacy of PACT in improving social-communication development in young children at risk for neurodevelopmental difficulties due to living in socio-economically disadvantaged regions of São Paulo, Brazil. Methods: Participants will be 160 children aged 2 years 0 months to 4 years 11 months with low social-communication abilities and their primary caregivers. Child-caregiver dyads will be recruited from public early childhood education centers in impoverished urban regions of the city of São Paulo, Brazil. Low social-communication abilities will be defined by Standard Scores <84 on the Socialization and/or Communication domains of the Vineland Adaptive Behavior Scales. Child-caregiver dyads will be randomized to receive 12 sessions (five months) of the PACT intervention (N=80) or five months of community support as usual plus psychoeducation (N=80). The primary outcome (parent-child interaction) and secondary outcomes (social-communication abilities assessed with the Vineland, neurophysiological activity during a live social interaction) will be measured pre- and post-intervention. All procedures will be performed in accordance with the CONSORT declaration for non-pharmacological interventions.
The main objective of the pilot phase of PGLEXPO will be to assess the faisability and to precise methodology of a case-control study designed for testing the impact of environmental and professional exposures on the tumoral risk in SDHx-mutation carriers
The elderly are weakened by the accumulation of chronic diseases. Their acute decompensation often leads to unscheduled hospitalization, which constitutes a breach of care with often serious consequences in terms of morbidity and mortality. Few studies have identified all the risk factors for unscheduled hospitalization in the very elderly. This project deals with the impact of air pollution on the very elderly as a source of physiological decompensations leading to unscheduled hospitalizations, in association with other individual and environmental risk factors. It complements the Rieho cohort that followed 973 elderly people on the same objective and enriches it with the use of sensors measuring the peri-individual atmospheric environment.
