The State University of New York (SUNY) – University of the West Indies (UWI) Health Research Consortium (HRC) was implemented in 2015 by the SUNY Global Health Institute (GHI) and the SUNY-UWI Center for Leadership and Sustainable Development. The goal was to advance public health in the Caribbean through collaborative research and education among faculty and students at SUNY and UWI. The Consortium is now a dynamic matrix addressing health priorities that were initially agreed upon with the Jamaica Ministry of Health and Wellness. The HRC has built a foundational matrix that is planning for cutting edge laboratory instrumentation, biomedical informatics system, seamless electronic medical records network, national laboratory data management system, and novel biotechnology (e.g., robotic surgery cluster). The SUNY-UWI partnership fills existing gaps through collaborative programs with the SUNY GHI that facilitate UWI faculty interactions with SUNY faculty and core resources and incubators that encourage collaborations while UWI infrastructure expands. The Health Research Consortium utilizes existing academic models at UWI and SUNY to promote collaboration, capacity building, and program implementation. Consortium teams develop sound business development models that foster sustained economic growth and form the pipeline for workforce development and career opportunities. The Caribbean diaspora and UWI alumni are engaged in working together on this effort. In addition, mentoring in K-12 and beyond is needed to create a vision for the next generations.

Background Nutritional rehabilitation during severe acute malnutrition (SAM) aims to quickly restore a healthy body weight, but rapid weight gain has been associated with later cardiovascular risk. We hypothesized that faster weight gain during SAM rehabilitation and post-hospitalization is associated with liver fat in adult survivors. Method Jamaican adult survivors of childhood SAM underwent abdominal CT scan to estimate liver fat as mean liver attenuation (MLA) and liver spleen ratio (L/S). Birth weight (BW) and anthropometry measured during, and post-hospitalization were abstracted from admission records. Results We studied 42 marasmus survivors (MRs) and 40 kwashiorkor survivors (KWs). MRs had a lower mean BW (SD) 2.5 (0.8) vs 3.0 (0.7) kg; p=0.01) and were more wasted (p

Background: Severe acute malnutrition (SAM) in infants may present as one of two distinct syndromic forms: non-edematous (marasmus), with severe wasting and no nutritional edema; or edematous (kwashiorkor) with moderately severe wasting. These differences may be related to developmental changes prior to the exposure to SAM and phenotypic changes appear to persist into adulthood with differences between the two groups. We examined whether the different response to SAM and subsequent trajectories may be explained by developmentally-induced epigenetic differences. Methods: We extracted genomic DNA from muscle biopsies obtained from adult survivors of kwashiorkor (n = 21) or marasmus (n = 23) and compared epigenetic profiles (CpG methylation) between the two groups using the Infinium® 450 K BeadChip array. Findings: We found significant differences in methylation of CpG sites from 63 genes in skeletal muscle DNA. Gene ontology studies showed significant differential methylation of genes in immune, body composition, metabolic, musculoskeletal growth, neuronal function and cardiovascular pathways, pathways compatible with the differences in the pathophysiology of adult survivors of SAM. Interpretation: These findings suggest persistent developmental influences on adult physiology in survivors of SAM. Since children who develop marasmus have lower birth weights and after rehabilitation have different intermediary metabolism, these studies provide further support for persistent developmentally-induced phenomena mediated by epigenetic processes affecting both the infant response to acute malnutrition and later life consequences. Funding: Supported by a Grant from the Bill and Melinda Gates Foundation (Global Health OPP1066846), Grand Challenge “Discover New Ways to Achieve Healthy Growth.” Evidence Before This Study: Previous research has shown that infants who develop either kwashiorkor or marasmus in response to SAM differ in birth weight and subsequently have different metabolic patterns in both infancy and adulthood. Added Value of This Study: This study demonstrates epigenetic differences in the skeletal muscle of adult survivors of marasmus versus kwashiorkor and these differences are in genes that may underlie the longer-term consequences. Implications of All the Available Evidence: These data are compatible with the different clinical responses to SAM arising from developmentally-induced epigenetic changes laid down largely before birth and provide evidence for the predictive adaptive response model operating in human development.
