Short-term impact of a wildfire on the homeostasis of Tropidurus oreadicus lizards.

Wildfires cause significant changes in natural habitats and can impact lizard populations. Through changes in the thermal environment, reduced prey availability, and increased exposure to parasite vectors, wildfires affect lizard physiology, immunity, and health. We sampled 56 Tropidurus oreadicus lizards from Cerrado savannas of Brazil living in two adjacent sites: one burned 14 days before the study, and the other unburned for 6 years. We logged the air temperatures of those sites throughout fieldwork. We assessed the short-term possible homeostatic imbalances caused by the fires via measuring body mass, circulating levels of corticosterone (CORT), leukocytes profile changes in heterophile-lymphocyte ratios (HLRs), innate immunity using the bacterial killing assay (BKA), and the diagnosis of hemoparasites using molecular techniques. The air temperature was significantly higher in the burned site. There was no difference in lizard body mass between the two sites, suggesting that prey availability was not affected by the wildfire. While parasite presence was seemingly not affected by fire, the timing of initial parasite infection for animals in the study was unknown, so we also evaluated parasitism as an independent variable relative to the other metrics. Our results showed that parasitic infections lead to reduced bactericidal capacity and body mass in lizards, suggesting clinical disease and depletion of innate immune resources. Moreover, we observed increased HLR with fire and parasitic infections and a strong negative correlation with BKA. These findings suggest that the increased environmental temperature following wildfires may lead to increased CORT and decreased BKA.

Barriers to and Strategies for Gaining Entry to Correctional Settings for Health Research.

Conducting research in corrections can contribute to improved individual and public health. Challenges to gaining entry to correctional settings to conduct research can impede research productivity, delay the launch of studies and inhibit researchers from proposing health research in corrections. The purpose of this paper is to share lessons learned from a large-scale corrections research project designed to develop computer-based learning modules to train front-line corrections personnel about geriatric and end-of-life care. Key lessons learned include the importance of building a team of experts, planning and punting, coordinating with institutional review boards and examining denied applications to inform future planning. To be effective in a correctional setting, leaders in nursing research and corrections nursing must work together within the contextual nature of prisons and jails to advance evidence-based practices for this vulnerable population. These lessons serve to establish best practices on how to access correctional settings and to enable more research in corrections.

Care and companionship in an isolating environment: inmates attending to dying peers.

The purpose of this study was to examine the values, beliefs, and perceptions of end-of-life (EOL) care held by inmates caring for peers approaching the end of their lives. The study is part of a broader participatory action research project to infuse enhanced EOL care into state prisons. Face-to-face interviews using a semistructured discussion guide were conducted with 17 male prisoners who were providing care for peers with advanced chronic illness and approaching end of life. Qualitative data were analyzed using content and thematic analyses. Key themes were getting involved, living the role, and transforming self through caring for others. As well, contextual features at the organizational, peer, and personal levels were identified, which either facilitated or impeded inmate caregiving. Provision of enhanced EOL care by inmate peers shows promise for improving prison community relations and morale, reducing suffering, and demonstrating care and compassion within the harsh prison environment. This study provides clear evidence that providing compassionate care for dying peers may result in transformative experiences for inmate caregivers. Implications for correctional nursing practice include providing training for inmate caregivers, including them in team meetings, and implementing grief support programs. Also, upholding nursing's code of ethics and watching for predatory behavior are critical.
