Cervical cancer (CC) is women’s fourth most common cancer worldwide. A worrying increase in CC rates in Hispanics suggests that besides Human papillomavirus infections, there may be other cofactors included in the epithelial microenvironment that could play a role in promoting the disease. We hypothesized that the cervical microbiome and the epithelial microenvironment favoring inflammation is conducive to disease progression in a group of Hispanics attending gynecology clinics in Puerto Rico. Few studies have focused on the joint microbiota and cytokine profile response in Hispanics outside the US, especially regarding the development of precancerous lesions. We aimed to investigate the relationship between the cervicovaginal microbiome and inflammation in Hispanic women living in PR while considering cervical dysplasia and HPV genotype risk. Cervical samples collected from 91 participants coming to gynecology clinics in San Juan, underwent 16S rRNA genes (V4 region) profiling, and cytokines were measured using Luminex MAGPIX technology.
Cytokines were grouped as inflammatory (IL-1β, TNFα, IFNγ, IL-6), anti-inflammatory (IL- 4, IL-10, TGFβ1), and traffic-associated (IL-8, MIP1a, MCP1, IP10). They were related to microbes via an inflammation scoring index based on the quartile and tercile distribution of the cytokine’s concentration. We found significant differences in the diversity and composition of the microbiota according to HPV type according to carcinogenic risk, cervical disease, and cytokine abundance. Community State Types (CSTs) represents a profile of microbial communities observed within the vaginal microbiome ecological niche, and Lactobacillus-depleted CST IV had ~ 90% dominance in participants with high-grade squamous intraepithelial lesions and high-risk HPV. The increasing concentration of pro-inflammatory
cytokines was associated with a decrease in L. crispatus. In contrast, dysbiosis-associated bacteria such as Gardnerella, Prevotella, Atopobium concomitantly increased with pro-inflammatory cytokines. Our study highlights that the cervical microbiota of Hispanics living in Puerto Rico is composed mostly of diverse CST profiles with decreased Lactobacillus and
is associated with a higher pro-inflammatory environment. The joint host-microbe interactionanalyses via cytokine and microbiota profiling have very good translational potential.

Your accomplishments serve as an inspiration to us all, and we look forward to witnessing your continued success in the future. Well done!

On March 31 2023, the Vice Presidency for Research and Innovation of the University of Puerto Rico and latinasteam.com recognized the scientific contributions of Doctors Emma Fernandez Repollet and Filipa Godoy-Vitorino in a ceremony in Rio Piedras, entitled “Symposium the Power of Women in the Science", celebrating the trajectory of outstanding women in science, technology, engineering, art and mathematics (STEAM) from the 11 campuses of the UPR.

We congratulate Dr. Filipa Godoy for receiving recognition as “Best INBRE Presentation" in her session by the NISBRE 2022 Organizing Committee. This symposium hosted a competitive field of distinguished young INBRE, COBRE, and CTR investigators selected among all 24 IDeA states to be presenters.  We therefore wish to congratulate all the oral presenters as well as our virtual poster presenters at this symposium for their outstanding presentations. Winners in other sessions and categories are listed below.
