Data Catalog

Basic clinical measures for all patients seen at Detroit Medical Center emergency departments, including hospital ID, reason for visit, age, gender, height, weight, systolic blood pressure, diastolic blood pressure, and patient ZIP code.

Prospective registry and biorepository of consecutive patients who present to emergency departments in the Detroit Medical Center with (1) an established history of hypertension (HTN) or (2) elevated blood pressure with no history of HTN. Patients are surveyed using validated Survey instruments including the SF-12 Health Survey, Patient Activation Measure short form (PAM-13), Berlin Obstructive Sleep Apnea Scale, Social Support Questionnaire short form (SSQ-6), Perceived Stress Scale (PSS-14), MacArthur Scale of Subjective Social Status, Six-Item Cognitive Impairment Test (6-CIT), and Brief Coping Orientation to Problems Experienced (Brief COPE). Biological specimens are obtained from consenting individuals. Other collected data include patient demographics, vital signs, physical examination, basic medical history, medications, electrocardiography, x-ray, and lab results.

Recent studies suggest the necessity of understanding the interactive effects of predation and productivity on species coexistence and prey diversity. Models predict that coexistence of prey species with different competitive abilities can be achieved if inferior resource competitors are less susceptible to predation and if productivity and/or predation pressure are at intermediate levels. Hence, predator effects on prey diversity are predicted to be highly context dependent: enhancing diversity from low to intermediate levels of productivity or predation and reducing diversity of prey at high levels of productivity or predation. While several studies have examined the interactive effects of herbivory and productivity on primary producer diversity, experimental studies of such effects in predator-prey systems are rare. We tested these predictions using an aquatic field mesocosm experiment in which initial density of the zooplankton predator Notonecta undulata and productivity were manipulated to test their interactive effects on diversity of seven zooplankton, cladoceran species that were common in surrounding ponds. Two productivity levels were imposed via phosphorus enrichment at levels comparable to low and intermediate levels found within neighboring natural ponds. We used open systems to allow for natural dispersal and behaviorally-mediated numerical responses by the flight-capable predator. Effects of predators on zooplankton diversity depended on productivity level. At low and high productivity, prey species richness declined while at high productivity it showed a unimodal relationship with increasing the predator density. Effects of treatments were weaker when using Pielou's evenness index or the inverse Simpson index as measures of prey diversity. Our findings are generally consistent with model predictions in which predators can facilitate prey coexistence and diversity at intermediate levels of productivity and predation intensity. Our work also shows that the functional form of the relationship between prey diversity and predation intensity can be complex and highly dependent on environmental context.

The Hispanic Community Health Study / Study of Latinos (HCHS/SOL) is a multi-center epidemiologic study in Hispanic/Latino populations to assess the role of acculturation in the prevalence and development of disease, and to identify factors playing a protective or harmful role in the health of Hispanics/Latinos. The target population of 16,000 persons of Hispanic/Latino origin, specifically Cuban, Puerto Rican, Dominican, Mexican, and Central/South American, were recruited through four Field Centers in Miami, San Diego, Chicago and the Bronx area of New York. During 2008-2011 study participants aged 18-74 years underwent an extensive clinic exam and assessments to determine baseline risk factors. Annual follow-up interviews are conducted to determine health outcomes of interest. During the 2014-2017 second clinic visit (Visit 2) participants were re-examined to again collect data predictive of various health outcomes of interest. In addition, a comprehensive reproductive history of women of childbearing age was assessed. The third clinic operations aka "visit" began January 2020 and will conclude in early 2023. HCHS-SOL provides the prevalence of 5 major, readily measured biomedical CVD risk factors (high serum cholesterol and blood pressure levels, obesity, hyperglycemia/diabetes, cigarette smoking), adverse CVD risk profiles (combinations of CVD risk factors), and CVD (coronary heart disease [CHD] and stroke) among US Hispanic/Latino adults of diverse backgrounds.
