13 Clinical Trials for Various Conditions
The purpose of this study is to evaluate how using an indoor air quality monitor can promote a smoke-free home for cancer patients who are enrolled in MSK's Tobacco Treatment Program.
Alaska Native children experience a high burden of respiratory disease, especially those in the Yukon-Kuskokwim (YK) Delta. Studies have shown that things like wood stove use, poor ventilation, and indoor tobacco smoke exposure can lead to poor indoor air quality inside the children's homes. This leads to more frequent and more severe respiratory infections in children. In the Yukon-Kuskokwim (YK) Delta, it's common for homes to have exposure to woodstoves and tobacco use. Both of these activities affect indoor air quality in homes. We know that high efficiency particulate air (HEPA) purifiers can reduce particulate matter and make air quality better. One way that we measure air quality is through particulate matter (PM2.5). One of the few studies that looked at this in the YK Delta found that PM2.5 levels that were nearly twice as high as homes with woodstoves in other states. We believe it is important to reduce the PM2.5 in YK Delta homes. However, the few studies that looked at HEPA purifiers in rural Alaska did not include homes where smokers lived. We know that breathing air with PM2.5 harms the lungs. We also know that HEPA filters can reduce PM2.5, which can mean reducing cough and wheeze in people with chronic lung conditions. We want to learn how HEPA filters work in homes with woodstoves or where a smoker lives, as it's likely these homes may have more PM2.5 than other homes. We expect that using HEPA filters will make the indoor air better and will mean decreased respiratory symptoms. We plan to include 15 households with a child less than 5 years old in the family. Households that join will be asked to: * Set up study equipment in their homes. * Run the study equipment for 12 weeks and do a weekly report of child's respiratory symptoms by phone or text. * Return the air-quality monitor equipment to the study team and keep the HEPA filters.
The primary objective is to determine whether continuous sensing, control and mitigation of home indoor air quality influences the frequency of asthma related symptoms, as measured by Serum IgE, Spirometry with exhaled Nitric Oxide, missed school and workdays, need for pharmacologic intervention (albuterol, oral steroids), frequency of sick visits to pulmonologist or primary care provider (PCP), urgent care / emergency department visits, and hospitalizations
The aims of this project are twofold: 1. to characterize indoor air quality components obtained from apartments with gas stoves and open kitchens in a cohort of Black adults with uncontrolled asthma recruited from federally qualified health centers and enrolled in the parent study. 2. to conduct a comprehensive assessment of feasibility, implementation, and acceptability of the study.
This is a single-center, open-label, parallel-cohort study to measure and compare the levels of selected secondhand smoke (SHS) constituents of a heated tobacco product (HTP) against combustible cigarettes (CC) after ad libitum smoking sessions by generally healthy smokers in an environmental testing chamber (ETC). Evaluation of SHS constituents detected during non-smoking sessions will be performed as a control.
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).
This CTSI pilot study will assess for benefit of a community health worker or nursing student taught green cleaning curriculum (developed by the local asthma coalition) provided to Milwaukee County day care staff. Consumer grade indoor air quality monitors will be deployed before and after the educational intervention to objectively monitor changes as a result of the intervention. Surveys regarding changes in cleaning practices by day care staff will also be obtained to assess changes resulting from the intervention.
The investigators will conduct a randomized, controlled, double-blind, crossover trial to determine whether the presence of a portable high-efficiency indoor air filter in the bedroom reduces respiratory symptoms in former smokers compared with placebo. The primary outcomes will be change in St. George's Respiratory Questionnaire - COPD (SGRQ-C) score associated with using a portable high-efficiency indoor air filter during the study period. Secondary outcomes of COPD exacerbations and hospitalizations, daily step counts, medication changes, spirometry, and cardiovascular outcomes will also be assessed.
Objectives (include all primary and secondary objectives) Specific Aim #1: To determine whether an air cleaner intervention to improve home air quality will improve respiratory symptoms, quality of life, lung function and reduce risk of exacerbations in former smokers with COPD. Hypothesis: An intervention using high-efficiency particulate air (HEPA) and carbon filter air cleaners in homes of former smokers with COPD will improve respiratory symptoms, quality of life, and lung function and reduce risk of COPD exacerbations compared with placebo (sham air cleaners). Specific Aim #2: To determine whether an air cleaner intervention to improve home air quality will be associated with intermediate outcome measures known to be linked with long term outcomes in COPD, including airway and systemic markers of inflammation and oxidative stress, in former smokers with COPD. Hypothesis 2: An intervention using HEPA and carbon filter air cleaners in homes of formers smokers with COPD will be associated with lower levels of markers of inflammation and oxidative stress known to be associated with adverse outcomes in patients with COPD.
The goal of this clinical trial is to learn about whether indoor air quality will improve over time in homes where occupants receive personalized information about levels of health-relevant air pollutants that includes practical, budget-friendly, and culturally relevant recommendations on actions they can take to improve their home's air quality. The rationale for the investigators' approach is that a rigorous intervention study design will generate robust evidence on the value of the in-home environmental data. Participating homes in both the intervention and control groups will receive three, one-week Home Health Box deployments spaced six weeks apart. After each of the first two deployments, homes in the intervention group will receive a Home Health Report with personalized information about in-home levels of health-relevant air pollutants and cost-sensitive recommendations on actions occupants can take to improve their home's air quality. The investigators will (a) investigate whether and how air quality changes over time in control and intervention homes and (b) survey intervention households on the utility of the Home Health Reports.
This is a multi-center randomized, sham-controlled clinical trial to determine the effectiveness of an air cleaner intervention aimed at improving indoor air quality on reducing COPD exacerbation risk and improving quality of life, functional status, rescue medication use.
The goal of this clinical trial is to compare indoor air quality and health in people exposed to air pollution, including possible exposure to wildfire smoke. The study will test the effect of using a do-it-yourself (DIY) air cleaner when air pollution is present to answer the following questions: * Do health outcomes differ between participants who use a DIY PAC and those who use a sham air cleaner? * How effective is the DIY air cleaner in reducing indoor concentrations of fine particles (PM2.5), and volatile organic compounds found in wildfire smoke? OR How effective is the DIY air cleaner in reducing indoor concentrations of fine and coarse particles (i.e., PM 10)? * What are barriers to use of a DIY air cleaner and what factors facilitate its use? Participants will be asked to do the following: * Participate in 5 home visits from study staff between July - October 2023 * Have an air quality sensor placed in the participant's bedroom for the whole study period * Have a small sensor attached to the main door of the participant's house to record when the door is open or closed (important for air quality inside) * Allow researchers to take air and dust samples in the participant's bedroom * Run a DIY air cleaner in the participant's bedroom for at least 6 nights while the participant sleeps * Complete 2 interviews * Allow study staff to collect 3 fingerstick blood samples * Allow study staff to collect 3 samples of fluid from inside the nose * Use the study air cleaner in the participant's bedroom during the study period The investigators will measure air quality in participating homes and measure health outcomes for participants. The investigators will compare outcomes of participants who use a DIY air cleaner with filters that work well to those of participants who use a DIY air cleaner with a placebo filter (one that does not work well to remove the air pollutants of concern). The goal of the study is to see if using the effective air cleaner leads to better health outcomes and indoor air quality.
Primary objective of this project is to measure the impact of passive control and active control systems on indoor pollution that is directly or indirectly related to ambient air pollution (smog). The first goal will be to measure baseline parameters for 50 homes, including information about the building, ventilation characteristics, pollution levels (indoors and outdoors), and occupant survey information. In a subset of these homes, either passive or active control systems will be installed and the impact of these systems on indoor concentrations. Participants will be enrolled on a rolling basis (5-15 persons studied at a given point in time) over a 16-month period. Participants will be followed for approximately 5 weeks and data obtained at three points in time: at enrollment (day 1 of study), after 1 week (baseline verification) and after four weeks with the control system in the home (at the end of study week 5).
