This research focuses on the plant-mediated green synthesis process to produce gold nanoparticles (Au NPs) using upland cress (Barbarea verna), as various biomolecules within the upland cress act as both reducing and capping agents. The synthesized gold nanoparticles were thoroughly characterized using UV-vis spectroscopy, surface charge (zeta potential) analysis, scanning electron microscopy-energy-dispersive X-ray spectroscopy (SEM-EDX), atomic force microscopy (AFM), attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), and X-ray diffraction (XRD). The results indicated the synthesized Au NPs are spherical and well-dispersed with an average diameter ~11 nm and a characteristic absorbance peak at ~529 nm.

Background: Haiti has the highest number of people living with HIV infection in the Caribbean/Latin America region. Medical male circumcision (MMC) has been recommended to help prevent the spread of HIV. We sought to assess knowledge, attitudes, practices and beliefs about MMC among a sample of health care providers in Haiti.

Objectives: To assess the safety, acceptability, and preliminary efficacy of a culturally-adapted disclosure intervention for perinatally HIV-infected combined antiretroviral therapy patients in Haiti and the Dominican Republic.

Design: A quasi-experimental trial was conducted comparing caregiver-youth pairs who completed the intervention [adapted Blasini disclosure model (aBDM)] to pairs who discontinued aBDM participation before disclosure. aBDM consists of five components: structured healthcare worker training; one-on one pre-disclosure intervention/education sessions for youth (describing pediatric chronic diseases including cancer, diabetes and HIV) and for caregivers (strengthening capacity for disclosure); a scheduled supportive disclosure session; and one-on-one postdisclosure support for caregivers and youth.

A pilot study is underway to assess safety and acceptability of an intervention to disclose their HIV infection status to status-naïve pediatric antiretroviral therapy patients in Hispaniola [the island shared by Haiti and the Dominican Republic (DR)]. Of 22 Haiti and 47 DR caregivers recruited to date, 68.2% Haiti and 34.

Psychological trauma resulting from natural disasters can negatively affect the health of persons living with HIV/AIDS (PLWH). This study examined relationships of alcohol use and exposure to the 2010 Haiti earthquake on symptoms of posttraumatic stress disorder (PTSD) among HIV-positive adults enrolled in an intervention study. Baseline data were collected from male and female PLWH, 19-56 years old on: alcohol consumption and related harms; anxiety; and coping strategies used to deal with HIV.

Purpose: Estimate the prevalence and burden of urinary incontinence (UI) on the quality of life (QOL) among adults (65 or older) with Medigap insurance.

Methods: Data were obtained from the health update survey (HUS), which contains questions on demographics, comorbid conditions, and the Veteran's RAND 12-item health status survey. The mail survey was fielded on a random sample of 15,000 insureds from 10 states in 2008.
