OBJECTIVE:To assess needs perceptions regarding the importance of and satisfaction with psychosocial support among cancer patients and survivors in Puerto Rico. METHODS:A cross-sectional study was conducted in 181 participants (70 men and 111 women) who were either undergoing cancer treatment (patients) or had completed cancer treatment (survivors). Participants completed a sociodemographic and clinical characteristics questionnaire, and the Psychosocial Needs Inventory (PNI). RESULTS:The participants reported having or having had prostate (36%) or breast (32%) cancer or some other cancer type (32%). Of the 149 participants reporting cancer type, 130 were classified as having a high perceived level of health and quality of life, and 19 were classified as having a low perceived level of health and quality of life. In terms of perceived needs, the highest level of importance were assigned to the Support Network (e.g. family, friends, neighbors, care professionals; M = 2.88, SD = 0.43) and Health Professional (e.g., patient-health professional relationship, etc.; M = 2.80, SD = 0.50) categories, and the Emotional and Spiritual category was given the lowest importance (e.g., help managing negative emotions and spiritual counseling, etc.; M = 2.62, SD = 0.66). These perceptions varied by gender, perceived health status, and date of diagnosis. Women assigned more importance to the Health Professional and Information categories. CONCLUSION/CONCLUSIONS:The results reflect the importance of considering psychosocial needs when providing psychosocial support to cancer patients and survivors. These findings are anticipated to inform services provided by psychosocial oncology support programs in Puerto Rico.

CONTEXT: Ventricular assist devices (VADs) improve quality of life in advanced heart failure (HF) patients, but there are little data exploring psychological symptoms in this population. OBJECTIVE: This study examined the prevalence of psychiatric symptoms and disease over time in VAD patients. METHODS: This prospective multicenter cohort study enrolled patients immediately before or after VAD implant and followed them up to forty-eight weeks. Depression and anxiety were assessed with PROMIS SF8a questionnaires. The panic disorder, acute stress disorder (ASD) and post-traumatic stress disorder (PTSD) modules of the Structured Clinical Interview for the DSM were used. RESULTS: Eighty-seven patients were enrolled. Post-implant, depression and anxiety scores decreased significantly over time (p=0.03 and p<0.001 respectively). Two patients met criteria for panic disorder early after implantation but symptoms resolved over time. None met criteria for ASD or PTSD. CONCLUSIONS: Our study suggests VADs do not cause serious psychological harms and may have a positive impact on depression and anxiety. Furthermore, VADs did not induce PTSD, panic disorder or ASD in this cohort.

Children who grow up in poverty are more likely to experience chronic stressors that generate "wear" on stress regulatory systems including the hypothalamus-pituitary-adrenal (HPA) axis. This can have long-term consequences for health and well-being. Prior research has examined the role of proximal family and home contributions to HPA axis functioning. However, there is evidence to suggest that more distal levels of context, including neighborhoods, also matter. Prior evidence has primarily focused on adolescents and adults, with little evidence linking the neighborhood context with HPA activity in infancy and toddlerhood. We tested whether neighborhood disadvantage (indexed by US Census data) was associated with basal salivary cortisol levels at 7, 15, and 24 months of child age in a large sample of families (N = 1,292) residing in predominately low-income and rural communities in the United States. Multilevel models indicated that neighborhood disadvantage was positively associated with salivary cortisol levels and that this effect emerged across time. This effect was moderated by the race/ethnicity of children such that the association was only observed in White children in our sample. Findings provide preliminary evidence that the neighborhood context is associated with stress regulation during toddlerhood, elucidating a need for future work to address possible mechanisms.

Inhalation of ozone (O₃), a gaseous air pollutant, causes lung injury, lung inflammation, and airway hyperresponsiveness. Macrophages, mast cells, and neutrophils contribute to one or more of these sequelae induced by O₃ Furthermore, each of these aforementioned cells express chemokine (C-C motif) receptor-like 2 (Ccrl2), an atypical chemokine receptor that facilitates leukocyte chemotaxis. Given that Ccrl2 is expressed by cells essential to the development of O₃-induced lung pathology and that chemerin, a Ccrl2 ligand, is increased in bronchoalveolar lavage fluid (BALF) by O₃, we hypothesized that Ccrl2 contributes to the development of lung injury, lung inflammation, and airway hyperresponsiveness induced by O₃ To that end, we measured indices of lung injury (BALF protein, BALF epithelial cells, and bronchiolar epithelial injury), lung inflammation (BALF cytokines and BALF leukocytes), and airway responsiveness to acetyl-β-methylcholine chloride (respiratory system resistance) in wild-type and mice genetically deficient in Ccrl2 (Ccrl2-deficient mice) 4 and/or 24 hours following cessation of acute exposure to either filtered room air (air) or O₃ In air-exposed mice, BALF chemerin was greater in Ccrl2-deficient as compared to wild-type mice. O₃ increased BALF chemerin in mice of both genotypes, yet following O₃ exposure, BALF chemerin was greater in Ccrl2-deficient as compared to wild-type mice. O₃ increased indices of lung injury, lung inflammation, and airway responsiveness. Nevertheless, no indices were different between genotypes following O₃ exposure. In conclusion, we demonstrate that Ccrl2 modulates chemerin levels in the epithelial lining fluid of the lungs but does not contribute to the development of O₃-induced lung pathology.

BACKGROUND: As an important indicator of mobility, driving confers a host of social and health benefits to older adults. Despite the importance of safe mobility as the population ages, longitudinal data are lacking about the natural history and determinants of driving safety in older adults. METHODS: The Longitudinal Research on Aging Drivers (LongROAD) project is a multisite prospective cohort study designed to generate empirical data for understanding the role of medical, behavioral, environmental and technological factors in driving safety during the process of aging. RESULTS: A total of 2990 active drivers aged 65-79 years at baseline have been recruited through primary care clinics or health care systems in five study sites located in California, Colorado, Maryland, Michigan, and New York. Consented participants were assessed at baseline with standardized research protocols and instruments, including vehicle inspection, functional performance tests, and "brown-bag review" of medications. The primary vehicle of each participant was instrumented with a small data collection device that records detailed driving data whenever the vehicle is operating and detects when a participant is driving. Annual follow-up is being conducted for up to three years with a telephone questionnaire at 12 and 36 months and in-person assessment at 24 months. Medical records are reviewed annually to collect information on clinical diagnoses and healthcare utilization. Driving records, including crashes and violations, are collected annually from state motor vehicle departments. Pilot testing was conducted on 56 volunteers during March-May 2015. Recruitment and enrollment were completed between July 2015 and March 2017. CONCLUSIONS: Results of the LongROAD project will generate much-needed evidence for formulating public policy and developing intervention programs to maintain safe mobility while ensuring well-being for older adults.

BACKGROUND: Animals exposed to anesthetics during specific age periods of brain development experience neurotoxicity, with neurodevelopmental changes subsequently observed during adulthood. The corresponding vulnerable age in children, however, is unknown. METHODS: An observational cohort study was performed using a longitudinal dataset constructed by linking individual-level Medicaid claims from Texas and New York from 1999 to 2010. This dataset was evaluated to determine whether the timing of exposure to anesthesia 28 days and 6 months and 1 year old and
