Pre- and peri-natal hurricane exposure alters DNA methylation patterns in children.

Hurricane Maria was the worst recorded natural disaster to affect Puerto Rico. Increased stress in pregnant women during and in the aftermath of the hurricane may have induced epigenetic changes in their infants, which could affect gene expression. Stage of gestation at the time of the event was associated with significant differences in DNA methylation in the infants, especially those who were at around 20-25 weeks of gestation when the hurricane struck. Significant differences in DNA methylation were also associated with maternal mental status assessed after the hurricane, and with property damage. Hurricane Maria could have long lasting consequences to children who were exposed to this disaster during pregnancy.

The psychological impact of the COVID-19 pandemic on physicians in Puerto Rico: a cross-sectional study after the second wave in 2021.

Introduction: Health care providers faced a challenge with the emergence of COVID-19 and its rapid spread. Early studies measuring the psychological impact of COVID-19 on the general population found high levels of anxiety and sleep disorders. The primary goal of this project was to assess the psychological impact of COVID-19 on physicians in Puerto Rico. Materials and methods: A cross-sectional study of physicians in Puerto Rico was conducted anonymously and electronically from February 2021 through April 2021. The electronic survey included socio-demographic data and 4 self-administered assessment tools (Generalized Anxiety Disorder-7, Perceived Stress Scale-10, Pittsburgh Sleep Quality Index and COVID-19 Organizational Support) for anxiety, perceived stress, sleep disturbances, and organizational support during the COVID-19 pandemic. Results: A total of 145 physicians completed the survey, with a female predominance of 53.5% and a majority practicing in the San Juan metropolitan area (50.3%). Mild anxiety symptoms were reported in 26.9% of physicians, and 33.8% had moderate to severe anxiety symptoms. Moderate to high perceived stress was found in 69.9% of participants, and women reported statistically significantly higher levels of anxiety symptoms (8.84 ± 5.99; p = 0.037) and stress (19.0 ± 6.94, p = 0.001). The Pittsburgh Sleep Quality Index reported 67.9% of physicians with global scores associated with poor sleep quality. Assessment of perceived organizational support found a high perception of work support (65.7%) but low perception of personal support (43.4%) and risk support (30.3%). A correlation analysis found a negative correlation for work and personal support, but a positive correlation for risk support, all statistically significant. Conclusion: COVID-19 had a lasting psychological impact in health care providers in Puerto Rico a year after the beginning of the pandemic. Our data supports the importance of organizational support and its correlation with the development of anxiety. It is thus essential to develop strategies to identify individuals at risk of experiencing psychological disturbances and to provide effective support for medical professionals during medical emergencies for their well-being and optimal delivery of patient care.

Cross-Species Convergence of Brain Transcriptomic and Epigenomic Findings in Posttraumatic Stress Disorder: A Systematic Review.

Introduction: Posttraumatic stress disorder (PTSD) is a complex multifactorial disorder influenced by the interaction of genetic and environmental factors. Analyses of epigenomic and transcriptomic modifications may help to dissect the biological factors underlying the gene-environment interplay in PTSD. To date, most human PTSD epigenetics studies have used peripheral tissue, and these findings have complex and poorly understood relationships to brain alterations. Studies examining brain tissue may help characterize the brain-specific transcriptomic and epigenomic profiles of PTSD. In this review, we compiled and integrated brain-specific molecular findings of PTSD from humans and animals. Methods: A systematic literature search according to the PRISMA criteria was performed to identify transcriptomic and epigenomic studies of PTSD, focusing on brain tissue from human postmortem samples or animal-stress paradigms. Results: Gene- and pathway-level convergence analyses revealed PTSD-dysregulated genes and biological pathways across brain regions and species. A total of 243 genes converged across species, with 17 of them significantly enriched for PTSD. Chemical synaptic transmission and signaling by G-protein-coupled receptors were consistently enriched across omics and species. Discussion: Our findings point out dysregulated genes highly replicated across PTSD studies in humans and animal models and suggest a potential role for the corticotropin-releasing hormone/orexin pathway in PTSD's pathophysiology. Further, we highlight current knowledge gaps and limitations and recommend future directions to address them.

Mental Well-being InSciEd Out: Health Partnerships with the Boys & Girls Clubs of Puerto Rico.

BACKGROUND: Mental health care is a top clinical concern for modern Puerto Rico, especially given a dramatically changing economic landscape paired with recurrent natural disasters. Youth are particularly at-risk due to long-term impacts of toxic stress and adverse childhood experiences on health and development. OBJECTIVES: Here we present a novel clinician-community-educator-scientist partnership to address Puerto Rican youth mental well-being and wellness. We deployed pilot health workshops within the Boys & Girls Clubs of Puerto Rico to build youth mental health conceptual understanding and competencies in stress recognition and management. The work in progress herein evaluates acceptability and feasibility of our curricular model. METHODS: Dialogue with community stakeholders guided curricular design of workshops for youth ages 6 to 13 and older. Prior to implementation, educators and volunteers attended a 1-day training on educational strategies. Workshop success was evaluated using qualitative approaches (i.e., narrative feedback, educator and volunteer reflections, youth Talking Drawings) to assess youth engagement, youth conceptual health understanding, and educator/volunteer impressions of feasibility and impact. RESULTS: Initial findings indicate high acceptability and feasibility of our curricular model. Youth engagement and enthusiasm were noted in educator feedback and continue to be sustained post-workshop. Preliminary analysis shows accompanying increases in youth conceptual mental health understanding, particularly for 6- to 12-year-olds in recognition of stress and healthy coping mechanisms. Reciprocal gains were observed for volunteers. CONCLUSIONS: Activities have evolved into a formal partnership called Semilla, which features expanded analysis of mental well-being and wellness outcomes. Our collaborative model continues to engage Puerto Rican youth in the science of their well-being.
