Principal investigator

Beverly Watkins

Using a patient-centered approach, this community engagement project seeks to build the capacity of local Community-based Organizations (CBOs) to help patients and potential patients get more involved in obstructive sleep apnea (OSA) screening and treatment initiatives, and create a guide that researchers can use to successfully partner with local CBOs and enhance patient-centered outcomes research (PCOR) initiatives.

COLLECTIVE TRAUMA AND RESILIENCE AMONG LGBTQ PEOPLE IN THE AFTERMATH OF THE ORLANDO MASS SHOOTING

Principal investigator

Perry Halkitis

In the aftermath of traumatic events, including mass shootings, people in communities that were geographically close to the event often experience symptoms of trauma. However, the recent shooting in Orlando, FL, appears to have been motivated, at least in part, by hatred towards lesbian, gay, bisexual, transgender, and queer-identified (LGBTQ) people. As such, experiences of trauma among people in the LGBTQ community may extend far beyond the geographic confines of the Greater Orlando area.

MOLECULAR MECHANISMS OF FILARIAL ENDOSYMBIOSIS (New York Blood Center) (NIH)

Nematodes cause the most common parasitic infections of humans, and the tissue-dwelling filarial worms produce the most severe pathology associated with these infections. Current control programs, however, which are universally based upon the mass distribution of a small arsenal of drugs are exceptionally vulnerable to failure in the event resistance develops. What is lacking is a method to kill or permanently sterilize the adult female parasites, making it critically important to support additional research leading to the discovery of novel drug targets.

UNDERSTANDING THE DIFFUSION AND IMPACT OF STATE ALCOHOL AND TRAFFIC POLICIES (NIH)

Principal investigator

Diana Silver

Traffic fatalities are the second largest contributor to years of life lost before age 75 and are the leading cause of death among youth aged 15-24 years. Alcohol involvement in these crashes has remained relatively steady despite overall declines in traffic fatality rates. Public policies (laws, regulations, penalties) concerning alcohol and car safety have contributed to these declines, but there is enormous variation in policies among states. To date, little scholarship has systematically investigated the impact of such a diverse regulatory environment on health outcomes.
