Screening for hepatitis B in the Bronx West African community with a blood pressure cuff: a cohort study.

Background: Hepatitis B (HBV) and hypertension (HTN) are prevalent in West Africa (WA). Inadequate control is common, and evaluation and management are challenging among immigrants due to unfamiliarity with the United States (US) healthcare system. While HBV is stigmatised, HTN is recognised as an important condition. We describe how a HTN screening program can facilitate HBV screening in the Bronx WA community. Methods: Thirty-minute HTN educational programs were delivered in collaboration with faith-based organisations, and 5-min presentations were presented upon request at community gatherings. Arrangements were made for those interested in a clinic visit where a questionnaire was completed, blood pressure (BP) measured, a free BP cuff provided, HBV testing performed, and referrals made. For those without ongoing care, insurance was arranged, and linkage to care provided. Findings: Seven 30-min and five 5-min presentations were conducted. After the 30-min presentation, 204 of 445 attendees (45.8%) requested a visit, and 68 (33.3%) attended the visit. After the 5-min presentation, 80 requested a visit and 51 (63.8%) attended the visit. A BP >140/90 mmHg was present in 122 individuals (48.4%), including 43 (17.1%) without a history of HTN and 39 (15.5%) with BP >160/90 mmHg. All except two who reported previous testing agreed to HBV testing. 19 (7.5%) were hepatitis B surface antigen positive. Transition into ongoing care was provided for 60 (33.9%) with HTN who were not integrated into the US healthcare system. Interpretation: HTN screening with a free BP cuff promotes HBV screening and US healthcare integration. Funding: No funding.

Eliminating hepatitis B vaccination disparities for West African immigrants.

BACKGROUND: Hepatitis B virus (HBV) infection is endemic in West Africa. There has been a significant increase in the Bronx West African (WA) community. To achieve HBV elimination, vaccination of non-immune individuals is important. Unfortunately, vaccine uptake in immigrant populations is at this time very limited. METHODS: An educational program was conducted by medical providers of WA origin in collaboration with local faith-based organizations, after which free HBV screening was offered. Non-immune individuals were initially recommended to contact their medical provider or referred to the Department of Health for vaccination. Beginning in 2021, the program offered vaccination. A questionnaire including reasons for vaccination in the program was offered. FINDINGS: Among the first500 individuals screened,34.6 % required vaccination. Among those screened before program vaccine availability, 72.2 % initiated the vaccination series,with38.2 % obtainingit at an outside setting and34 % returning when available through the program.Among patients screened after program vaccineavailability, 92.1 % initiated the series.Of those receiving vaccination in the program and completing the questionnaire,70.7 % had access to care but chose vaccination by the program because of the trust instilled by WA personnel. INTERPRETATION: Our findings demonstrate the effectiveness of integrating vaccination into an HBV screening program for an immigrant population. It emphasizes the importance of timeliness and cultural sensitivity.

Multiple sgRNAs for one-step inactivation of the duplicated acetyl-coenzyme A carboxylase 2 (ACC2) genes in Brassica napus.

Efficient plastid transformation in Arabidopsis (Arabidopsis thaliana) requires genetic lines that are hypersensitive to spectinomycin due to the absence of a chloroplast acetyl-coenzyme A carboxylase (ACCase) encoded in the acetyl-coenzyme A carboxylase 2 (ACC2) nuclear gene. To obtain plastid transformation-competent oilseed rape (Brassica napus), we inactivated all nuclear encoded, chloroplast targeted ACCase copies using CRISPR-Cas9. Brassica napus (2n = 38, AACC) is a recent interspecific hybrid of Brassica rapa (2n = 20, AA) and B. oleracea (2n = 18, CC) and is expected to have at least two ACC2 copies, one from each parent. The sequenced genome has two ACC2 copies, one that is B. rapa-like and one that is B. oleracea-like. We designed single-guide RNAs (sgRNAs) that could simultaneously inactivate both nuclear ACC2 copies. We expressed Cas9 from a chimeric egg cell promoter 1.2 (EC1.2p) known to yield homozygous or biallelic mutants in Arabidopsis in the T1 generation. To maximize the probability of functionally inactivating both orthologs in a single step, each of the two vectors carried four sgRNAs. Four T0 transgenic lines were obtained by Agrobacterium tumefaciens-mediated hypocotyl transformation. Amplicon sequencing confirmed mutations in ACC2 genes in 10 T1 progeny, in seven of which no wild-type (WT) copy remained. The B. napus T2 seedlings lacking WT ACC2 gene copies exhibited a spectinomycin hypersensitive phenotype, suggesting that they will be a useful resource for chloroplast genome transformation.

Furthering the One Health Mission:: Template for Establishing Student-Run One Health Groups on College Campuses.

INTRODUCTION: Although it has been well-established that animal health and environmental health impact human health, there is a lack of inclusion of One Health in the education of medical and undergraduate students1. Most students, in fact, are not aware of the One Health initiative. RATIONALE: Due to the fundamental lack of One Health knowledge across all involved disciplines but particularly healthcare fields, educating students at the institutional level is desirable to provide early exposure. Education should influence more integrated practice for future citizens, including those in the health professions. Methods: A framework for commencing a successful One Health student club is outlined, with steps that include distinguishing the club, writing a Constitution, advertising to students, holding elections, formally establishing the University recognized club and expanding its presence on campus. Results: An undergraduate student One Health group at Rutgers University was established, and another one is currently being established at Rutgers Robert Wood Johnson Medical School. Despite the fact that One Health is an established, global initiative, there was a great deal of education necessary to alert students as to what One Health is. Although there also were multiple operational issues that had to be addressed, once commenced at the undergraduate level, it has been a very successful campus initiative. Discussion: From the experience at Rutgers University, One Health student groups can be established that further the message of One Health. Public health implications: Having a One Health presence at educational institutions via student groups will raise awareness of One Health principles, especially as they relate to public health.
