"We Feel Alone and Not Listened To": Parents' Perspectives on Pediatric Serious Illness Care in Somali, Hmong, and Latin American Communities.

PURPOSE: The experience of ethnically diverse parents of children with serious illness in the US health care system has not been well studied. Listening to families from these communities about their experiences could identify modifiable barriers to quality pediatric serious illness care and facilitate the development of potential improvements. Our aim was to explore parents' perspectives of their children's health care for serious illness from Somali, Hmong, and Latin-American communities in Minnesota. METHODS: We conducted a qualitative study with focus groups and individual interviews using immersion-crystallization data analysis with a community-based participatory research approach. RESULTS: Twenty-six parents of children with serious illness participated (8 Somali, 10 Hmong, and 8 Latin-American). Parents desired 2-way trusting and respectful relationships with medical staff. Three themes supported this trust, based on parents' experiences with challenging and supportive health care: (1) Informed understanding allows parents to understand and be prepared for their child's medical care; (2) Compassionate interactions with staff allow parents to feel their children are cared for; (3) Respected parental advocacy allows parents to feel their wisdom is heard. Effective communication is 1 key to improving understanding, expressing compassion, and partnering with parents, including quality medical interpretation for low-English proficient parents. CONCLUSIONS: Parents of children with serious illness from Somali, Hmong, and Latin-American communities shared a desire for improved relationships with staff and improved health care processes. Processes that enhance communication, support, and connection, including individual and system-level interventions driven by community voices, hold the potential for reducing health disparities in pediatric serious illness.

High-affinity memory B cells induced by SARS-CoV-2 infection produce more plasmablasts and atypical memory B cells than those primed by mRNA vaccines.

Although both infections and vaccines induce memory B cell (MBC) populations that participate in secondary immune responses, the MBCs generated in each case can differ. Here, we compare SARS-CoV-2 spike receptor binding domain (S1-RBD)-specific primary MBCs that form in response to infection or a single mRNA vaccination. Both primary MBC populations have similar frequencies in the blood and respond to a second S1-RBD exposure by rapidly producing plasmablasts with an abundant immunoglobulin (Ig)A+ subset and secondary MBCs that are mostly IgG+ and cross-react with the B.1.351 variant. However, infection-induced primary MBCs have better antigen-binding capacity and generate more plasmablasts and secondary MBCs of the classical and atypical subsets than do vaccine-induced primary MBCs. Our results suggest that infection-induced primary MBCs have undergone more affinity maturation than vaccine-induced primary MBCs and produce more robust secondary responses.

Strategies to Enhance Culturally Responsive Research: Community Research Recommendation Tool.

Under-representation of minorities in research hinders the ability to address persistent societal inequities. To understand how to increase the cultural responsiveness of research, a community-academic partnership conducted listening sessions and community forums with African Americans in North Carolina, Native Hawaiians in Hawai'i, and Hmong and Latino/a/x communities in Minnesota. Participants shared their concerns and desires for research, as well as generated strategies aimed at communities, researchers, and partnerships to enhance culturally responsive research practices. These findings resulted in a Community Research Recommendation Tool (CRRT) that can be used to guide community members, researchers, and partnerships as they build equitable research partnerships that honor cultural practices, account for sociopolitical contexts, and aim to redress societal inequities.

US Immigration Westernizes the Human Gut Microbiome.

Many US immigrant populations develop metabolic diseases post immigration, but the causes are not well understood. Although the microbiome plays a role in metabolic disease, there have been no studies measuring the effects of US immigration on the gut microbiome. We collected stool, dietary recalls, and anthropometrics from 514 Hmong and Karen individuals living in Thailand and the United States, including first- and second-generation immigrants and 19 Karen individuals sampled before and after immigration, as well as from 36 US-born European American individuals. Using 16S and deep shotgun metagenomic DNA sequencing, we found that migration from a non-Western country to the United States is associated with immediate loss of gut microbiome diversity and function in which US-associated strains and functions displace native strains and functions. These effects increase with duration of US residence and are compounded by obesity and across generations.
