Epidemiological intelligence community network intervention: a community response for COVID-19 community transmission.

BACKGROUND: Expanding and providing access to early detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) through testing community-based strategies among socially vulnerable communities (SVC) are critical to reducing health disparities. The Epidemiological Intelligence Community Network (EpI-Net) community-based intervention sought to increase coronavirus 2019 (COVID-19) testing uptake and prevention practices among SVC in Puerto Rico (PR). We evaluated EpI-Net's community leaders' capacity-building component by assessing pre-post COVID-19 public health workshops' tests' score changes and satisfaction among trained community leaders. METHODS: A total of 24 community leaders from SVC in PR have completed four community workshops. Pre- and post-assessments were completed as part of the health promotors training program to evaluate participants' tests score changes and satisfaction outcomes. RESULTS: Preliminary results showed: (1) high intervention retention levels of community leaders (85.7% acceptance rate); (2) change in post-test scores for community engagement strategies (p = 0.012); (3) change in post-test educational scores in COVID-19 prevention practices (p = 0.014); and (4) a change in scores in public health emergency management strategies (p < 0.001). CONCLUSIONS: The overall workshop satisfaction was 99.6%. Community leaders have shown the importance of community capacity building as a key component for intervention feasibility and impact. TRIAL REGISTRATION: Our study was retrospectively registered under the ClinicalTrial.gov ID NCT04910542.

Women with endometriosis have a higher DNA repair capacity and diminished breast cancer risk.

INTRODUCTION: Breast cancer (BC) and endometriosis are important reproductive health diseases for women. Although endometriosis is not a malignant condition, some of its characteristics mimic that of a malignancy. Endometriosis is associated with increased risk of certain cancers; however, whether it alters BC risk is unclear. This study evaluates the association of endometriosis and BC and explores whether DNA repair capacity (DRC) plays a role in such a relationship. MATERIALS AND METHODS: A case-control study of 991 women (385 with BC and 606 controls, all recruited over 5 years) was undertaken in Puerto Rico. Eighty participants with self-reported surgically diagnosed endometriosis were identified, 20 of whom also had a diagnosis of BC. Data from a structured questionnaire and DRC measurements were assessed to determine the association between BC, DRC, and endometriosis. RESULTS: Participants with BC cases were 50% less likely to have history of endometriosis (OR = 0.5 95%CI: 0.3, 0.9, p = 0.038) than women without BC controls. Findings that did not reach statistical significance included the following: women with history of endometriosis had a slightly higher DRC level than those without it; BC cases and history of endometriosis were less likely to have had endometriosis diagnosis before age 38 as compared to controls with endometriosis. DISCUSSION: Here we report an inverse association between endometriosis and BC, the former possibly conferring a protective effect on the latter. Although the mechanisms involved are unknown they may include protection provided by higher DRC and or hormonal treatments for endometriosis. A larger sample of endometriosis cases is necessary to confirm these results and answer the question of whether a higher DRC capacity may contribute to this potential protection, and to identify other factors at play.
