Project description:<p>Mother and infant pairs were enrolled in the Rhode Island Child Health Study (RICHS) at the Woman and Infant's Hospital from 2009 through 2014.</p> <p>This population consists of singleton, term infants (≥37 weeks gestation) born without serious pregnancy complications or congenital or chromosomal abnormalities. Given a priority interest to study fetal growth, the RICHS population was oversampled for both large for gestational age (LGA, >90% 2013 Fenton Growth Curve) and small for gestational age (SGA, <10% 2013 Fenton Growth Curve) infants. </p>

Project description:Lifespan Cancer Institute serves over 50% of cancer patients in the state. Rhode Island is known for strong medical care and high rates of cancer screening with mammography and colonoscopy. However, cancer screening has plummeted during the COVID-19 pandemic, in part to closing physician offices and stopping non-urgent medical procedures. In addition, anecdotal reports suggest the public remains concerned about returning to physician’s offices and risking possible exposure to COVID-19. As in the United States as a whole, COVID-19 has disproportionately impacted ethnic and minority individuals within underserved communities; and in Rhode Island, African Americans, Hispanics and undocumented individuals living in communities such as Central Falls, Pawtucket, Providence, East Providence and North Providence have had the highest rate of COVID-19. These communities are also impacted by healthcare disparities to access and affordability of healthcare, and as such, may be among the least likely to resume cancer screening.
The Lifespan Cancer Institute will institute a project to address health disparities in cancer screening during the pandemic through the use of a targeted campaign involving social media. The goals will be to re-establish screening in the era of COVID-19 and ensure timeliness of care for those found to be at risk, or are positive for, cancer.
Project description:The genetic foundation of chicken tail feather color is not very well studied to date, though that of body feather color is extensively explored. In the present study, we used a synthetic chicken dwarf line (DW), which was originated from the hybrids between a black tail chicken breed, Rhode Island Red (RIR) and a white tail breed, Dwarf Layer (DL), to understand the genetic rules of the white/black tail color. The DW line still contain the individuals with black or white tails, even if the body feather are predominantly red, after more than ten generation of self-crossing and being selected for the body feather color. We firstly performed four crosses using the DW line chickens including black tail male to female, reciprocal crosses between the black and white, and white male to female to elucidate the inheritance pattern of the white/black tail. We found that (i) the white/black tail feather colors are independent of body feather color and (ii) the phenotype are autosomal simple trait and (iii) the white are dominant to the black in the DW lines. Furtherly, we performed a genome-wide association (GWA) analysis to determine the candidate genomic regions underlying the tail feather color by using black tail chickens from the RIR and DW chickens and white individuals from DW lines.
