The epicenter of the COVID-19 crisis since March 17, 2020—the New York metropolitan area—is home to some of the largest Latino immigrant communities in the nation. These communities have long faced barriers to health care access, challenges due to immigration status, and financial and labor instability. The COVID-19 pandemic has aggravated these existing issues in a vulnerable, often forgotten, immigrant community. It has been challenging for this population to access public information regarding COVID-19 testing, treatment, and assistance programs because this information has seldom been disseminated in Spanish and even less frequently in Portuguese. While long-term solutions will require time and changes to policy, some short-term measures can mitigate the current situation. The authors share their experience from Newark, New Jersey, where partnerships of public and private community-based organizations (CBOs) have been successful in establishing trust between the health care system and a fearful Latino community. The Ironbound Initiative, a student group at Rutgers New Jersey Medical School in Newark, New Jersey, has partnered with Mantena Global Care, a Brazilian CBO in Newark, to facilitate dissemination of COVID-19–relevant information. Medical student volunteers, removed from their clinical duties, serve as virtual patient navigators, using social media to reach community members with the goals of improving awareness of precautions to take during the pandemic and of increasing access to needed medical care. These students have collaborated with colleagues in other disciplines to provide necessary legal guidance to community members fearful of seeking care because of their immigration status. The authors urge other academic institutions across the country to recruit multidisciplinary teams of medical, health professions, and law students invested in their local communities and to empower students to partner with CBOs, immigrant community leaders, faith-based organizations, hospitals, and local authorities to support these vulnerable communities during this crisis.

ABSTRACT. Polyploid induction has been used for plant breeding to produce bigger and more robust plants than diploid types. The present study aimed to develop a methodology for in vitro induction of polyploidy in cassava. Apical and lateral microcuttings from the BRS Formosa variety were treated with six oryzalin concentrations for 24 and 48 h. The same methodology was used for colchicine with different concentrations. After 45 days of cultivation and an additional 45 days of subculture, the viability of the explants was assessed and plant acclimatization was performed. Ploidy was determined using flow cytometry. Oryzalin dose and exposure negatively affected cassava explant growth and development compared to untreated explants. Furthermore, apical and lateral explants responded differently to the treatments, showing a diversity in antimitotic sensitivity and effect that is tissue-type specific. In contrast, the doses of 1.25 to 6.25 mM colchicine resulted in high mortality of cassava explants. Therefore, the type of antimitotic affects the morphophysiological behavior of cassava plants in vitro, although apical explants have higher viability and regenerative capacity compared to lateral explants. In addition, the lateral explants have lower mixoploid rates compared to apical explants. Of the 310 plants generated by oryzalin treatments, 277 were diploid, 31 were mixoploid, and 2 were tetraploid. Exposure to oryzalin led to low rate of tetraploids and colchicine caused phytotoxic reactions and death of the explants. The tetraploids were multiplied in vitro to evaluate their yield in the field as well as their behavior against abiotic and biotic stress.
