Filter by:Environmental toxins exert damaging health effects in workers. Thousands of responders who worked or volunteered on the World Trade Center (WTC) rescue and recovery effort following the September 11, 2001 attacks suffer from health conditions or may be at increased risk for worsening health. In a pilot study, investigators identified the first evidence of kidney damage in subjects with very high exposure at Ground Zero. Specifically, noted was a preliminary association between the intensity of particulate matter exposure and albuminuria, a marker of early chronic kidney disease (CKD), systemic endothelial dysfunction, and increased cardiovascular risk. The long-term goal is to minimize the risk of CKD and cardiovascular disease (CVD) among individuals exposed to inhaled toxins. The primary objective of this research is to quantify the risk of kidney damage among first responders to the WTC attack and to determine the relationship to particulate matter exposure as well as determine an association between renal and cardiovascular damage in first responders and to explore potential mechanisms. The central hypothesis is that exposure to inhaled particulate matter causes systemic inflammation and endothelial dysfunction that result in chronic kidney and cardiovascular damage. This hypothesis will be investigated in a subgroup of participants from a previously conducted NIOSH-funded study "Pulmonary Function Abnormalities, Diastolic Dysfunction and WTC Exposure: Implications for Diagnosis and Treatment" ("WTC-CHEST," PI Mary Ann McLaughlin). The proposed study will capitalize on unique resources in WTC-CHEST, including the standardized collection of data on particulate matter exposure and shared risk factors for CKD and cardiovascular disease, and cardiopulmonary function testing. The output from this proposal is anticipated to have a broad impact on understanding the health effects of inhaled particulate matter.
There are prevalent micronutrient and fiber deficiencies in a significant proportion of US population, particularly among the overweight or obese. Intensive lifestyle counseling results in modest, measurable dietary improvements and weight stabilization, yet falls short of restoring optimal nutritional status and metabolism. A carefully formulated nutritional supplement bar (referred to as the CHORIBAR) delivered in a whole food matrix may correct micronutrient deficiencies in overweight or obese adults and children. This may have a beneficial impact on traditional indices of insulin dysregulation and the metabolic syndrome, gut inflammation, redox status, immune function and DNA integrity, and may favorably influence weight change and fat distribution. The investigators believe that the improvements seen with CHORIBAR trials will be mediated at the level of generalized enhancement in cellular metabolism that are not readily achieved with lifestyle counseling alone. The investigators suspect this is due to many nutritional barriers, some of which are disproportionately borne by inner city populations, such as cost and access to healthy food. The investigators hypothesize that a nutritional supplement like the CHORIBAR will facilitate restoration of optimal nutritional status and improve metabolic and weight outcomes.
The purpose of this research is to estimate the outcomes in health and cost of the follow-up of patients with pacemakers. The initial hypothesize of this study is that remote monitoring of pacemaker will show a best relation of outcomes in costs and effectiveness than the conventional follow-up in hospital.
The ultimate goal of our partnership with local African-American churches is to implement an effective, multi-component intervention to increase awareness of the critical importance of healthy lifestyle in the prevention of cardiovascular disease (CVD). We will utilize the American Heart Association (AHA) prevention strategy, "Life's Simple 7" to address the major risk factors for CVD: diet, smoking, physical inactivity, hypertension, diabetes, cholesterol and obesity in order to improve overall cardiovascular health. Our main strategy consists of a community-based participatory research approach that involves focus groups to assess participant knowledge and beliefs about CVD risk factors prior to program initiation. We will also determine participant dietary and exercise practices, knowledge and perceptions related to healthy lifestyle and chronic diseases, demographic/health status information, health care utilization, biometrics (weight, blood pressure, blood tests for glucose and cholesterol, etc.) and attitudes about medical research at baseline, program completion and 6-month follow-up.

Despite advances in cardiovascular care, the occurrence of heart failure (HF) is steadily increasing. The increase in HF rates poses enormous challenges, as once an individual becomes symptomatic or requires hospitalization with HF, the prognosis remains poor. Therefore, prevention of HF is essential. HF prevention is a critical issue as HF risk factors that include common medical conditions such as hypertension and diabetes are also increasing. However, not everyone with these risk factors develops HF. Using novel blood tests, the investigators propose to identify and treat subjects at higher HF risk to see if the investigators can stabilize or improve ultrasound measures known to be associated with HF risk. This study will enroll only Veterans.
A human clinical consumption trial will be performed in volunteers with increased risk factors for cardiovascular disease (Metabolic Syndrome), which includes obesity and diabetes and related conditions over a period of 12 weeks with blood draws at baseline (0 weeks), 4, 8, and 12 weeks and a 24 hr urine collection on each blood draw day.
Project CONNECT ("Community-based Organizations Neighborhood Network: Enhancing Capacity Together") is a randomized controlled trial that involves 22 community-based organizations (CBOs) located in Baltimore, MD. Half of these organizations were randomly assigned to the intervention group using a constrained cluster randomization process. The remaining 11 are a part of the control intervention group. The intervention is a co-developed set of IT tools hypothesized to improve the connections among intervention CBOs, Johns Hopkins health care facilities and CBO clients.
The investigators will conduct a prospective observational cohort study to investigate factors that influence contraceptive method utilization among women with medical conditions. The investigators will also investigate how women with medical conditions access to contraception and family planning fellowship trained specialist. After the baseline questionnaire, there be a 3 month and 6 month follow up questionnaire to investigate continuation and satisfaction with the contraceptive method. This study is unique because it will allow us to explore doing collaborative family planning research at the multiple UC medical campuses.
The study tested whether a pharmacist-run cardiovascular risk service (CVRS) at the University of Iowa can increase use of national standards of care in clinics
