Background: Mounting data suggest that exposure to chronic stress is associated with worse breast cancer outcomes. This study aimed to explore the impact of social environmental adversity (SEA, e.g., child abuse, crime, sexual, and physical violence), depressive symptomatology, and anxiety on immune cell infiltration into the breast tumor microenvironment. Methods: Participants (n = 33) completed a series of surveys assessing depression and anxiety symptoms, adverse childhood events (ACE), and trauma history. Tumor-associated macrophages (CD68+), B cells (CD19+), and T cells (CD3+) were identified by immunohistochemical analyses of formalin-fixed paraffin-embedded tumor samples and quantified. Spearman rank tests were used to explore the relationships between the variables studied. Results: Exposure to SEA was high (ACE = 72%, exposure to crime = 47%, and exposure to physical/sexual assault = 73%) among participants. Moreover, 30% reported a comorbid history of depression and ACE; 39% reported one or more traumatic events, and clinically significant depression symptomatology, while 21% reported trauma history and significant anxiety symptomatology. Increased tumor-infiltrating B cells were significantly correlated with exposure to crime, anxiety symptoms, and exposure to an ACE. The ACE plus anxiety group presented the highest infiltration of B cells, T cells, and macrophages. Conclusion: These findings support a role for SEA, anxiety symptoms, and depression as potential modulators of the immune tumor microenvironment in breast cancer.

On 7 January 2020, the southern region of Puerto Rico was struck by a 6.4 magnitude earthquake, followed by continual seismic activity. Our team performed secondary analyses to explore the relationship between exposure to seismic activity, protection (support) received, and barriers to health care access for cancer patients. Methods: The research team collected data from the database of a longitudinal case-control cohort parent study concerning the impact of Hurricane Maria in Puerto Rican cancer patients. The participants from the parent study were recruited in community clinics. The extracted data was collected from 51 cancer patients who completed the parent study’s interviews from January–July 2020 (seismic activity period). Barriers to health care were assessed using the Barrier to Care Questionaries (BCQ), which is composed of five subscales: skills, marginalization, knowledge and beliefs expectations, and pragmatics. Exposure to seismic activity and protection was assessed using their respective subscales from the Scale of Psychosocial Impact of Disasters. Results: The results showed a significant relationship between exposure to seismic activity and barriers to health care (p < 0.001) and its five subscales (p < 0.01). These results shed light on potential access to care barriers that could hinder cancer patient treatment in the event of a natural disaster.

Objective: The present study explored the association between the losses incurred due to breast cancer diagnosis, symptoms of depression, PANIC/GRIEF, and contextual factors within the context of Hispanic/Latina (H/L) patients diagnosed with breast cancer (BC). Methods: This study was a cross-sectional study of adult H/L BC patients (n = 129). The participants were H/L women diagnosed with breast cancer (stages 0–4) in the past five years. Sociodemographic variables were assessed, as well as depression symptoms (Patient Health Questionnaire-9; Spanish version), grief (The Affective Neuroscience Personality Scales, Grief subscale; Spanish version), and general losses (Grief diagnostic instrument for general practice, loss categories section). Results: The mean age for the sample was 55.37 (SD = 11.57). The most frequent non-death-related losses were loss of liberty (f = 63, p = 48.8%), followed by fear of own death (f = 67, p = 51.9%) and loss of quality of life (f = 65, p = 50.4%). A higher mean rank was observed in depressive symptomatology scores for those who experienced loss of liberty (U = 73.91, p < 0.008), quality of life (U = 77.30, p < 0.001), and fear of their own death (U = 74.88, p < 0.002). The results indicate a significant positive relationship between the number of reported losses and depressive symptomatology (r = 0.340, p < 0.001). In terms of contextual factors, the participants who reported their income not being enough to cover their expenses reported a greater number of losses related to diagnosis (U = 74.67, p < 0.001) and more depressive symptomatology (U = 69.84, p = 0.041). Moreover, a relationship was observed between grief and academic levels (r = −0.234, p = 0.008). Likewise, a relationship was observed between age and the number of losses (r = −0.461, p < 0.001). Conclusions: Our results provide new evidence on how primary non-death-related losses due to a breast cancer diagnosis impact the mental health of H/L BC patients.

Background: Studies evaluating the effects of natural disasters on cancer outcomes are scarce, especially among USA ethnic minority groups, and none have focused on the effects of concurrent natural disasters and the COVID-19 pandemic. The goal of this secondary data analysis is to explore the impact of concurrent exposure to COVID-19 and earthquakes on psychological distress and symptom burden among Puerto Rican cancer survivors. Methods: This secondary data analysis (n = 101) was part of a longitudinal case–control cohort study (n = 402) aimed at describing unmet psychological needs among Puerto Rican cancer patients and non-cancer subjects previously exposed to Hurricane María in 2017. The research team pooled data from participants (cancer survivors and non-cancer group) from their baseline assessments and from follow-up assessments conducted during January–July 2020 (earthquake and the lockdown period). A descriptive, paired t-test, non-parametric mean rank test, and two-sided Pearson correlation analyses were performed. Results: Psychological distress and cancer symptom burden diminished over time. Resilience was significantly correlated with all the psychological and symptom burden variables during both pre- and post-earthquake and COVID-19 assessment periods. Conclusions: The results support the role of resilience, social support, and post-traumatic growth as potential protective factors preventing psychological distress and diminishing cancer symptom burden among cancer survivors exposed to natural disasters and the COVID-19 pandemic.

Background: Puerto Rico (PR) is highly vulnerable to hurricanes, which severely impact cancer survivors by causing healthcare disruptions and increasing stress. This study investigates the reliability and factor structure of the Hurricane Hazards Inventory (HHI) and its relationship with psychological distress among cancer survivors and non-cancer controls in PR. Methods: Using secondary data from a longitudinal study following Hurricane Maria (HM), the baseline assessment included sociodemographic data from participants, HHI, Patient Health Questionnaire (PHQ-8), and Generalized Anxiety Disorder (GAD-7). Statistical analyses involved descriptive statistics, Exploratory Factor Analysis (EFA), and Partial Least Squares Structural Equation Modeling (PLS-SEM). Results: Among 260 participants, 78.7% were women, with a median age of 58.0 years. EFA reduced the HHI to 17 items grouped into three factors explaining 62.6% of the variance with excellent reliability (Cronbach’s alpha 0.91). The three factors also showed good to excellent reliability (alpha 0.81 to 0.92). The median HHI score was 11.0 (range 4.0–26.5) out of 68. PLS-SEM revealed a direct effect of being a cancer survivor and tertiary hazards on depression and anxiety. Conclusion: The HHI is a valid and reliable tool for assessing mental health impact in cancer survivors after hurricanes. However, the study had limitations, including its small sample size and lack of control for all confounding variables. Future research with larger and more diverse samples is needed to further validate the HHI and examine its generalizability.

Breast cancer (BC) is the leading cancer diagnosis among women in Puerto Rico. Psychological distress is prevalent in this population, and social determinants may exacerbate this risk. This study examines whether sociodemographic characteristics, financial burden, and social support levels are associated with symptoms of anxiety and depression in Puerto Rican women with BC. A quantitative secondary analysis was conducted on a sample of 208 Hispanic women with BC, utilizing the Patient Health Questionnaire (PHQ-8) and the Generalized Anxiety Disorder (GAD-7) questionnaire. These scores were compared with sociodemographic values and Interpersonal Support Evaluation List (ISEL-12) scores, establishing statistical significance through association, parametric, and non-parametric tests, and regression models. 38.5% and 26.4% of participants showed clinically significant symptoms of depression and anxiety, respectively. Age and perceived income showed significant associations with psychological outcomes. However, regression analysis revealed perceived income as the only significant predictor for both depression and anxiety. Tangible and belonging support were significantly lower in participants with symptoms of depression, while appraisal support was significantly lower in participants with symptoms of anxiety. Findings highlight the influence of perceived financial stress on mental health and the need for psychosocial interventions tailored to the patients’ economic context.
