Objetivo: avaliar os principais fatores estressores apontados pelos pacientes em uma unidade cardiointensiva. Método: pesquisa descritiva, quantitativa, realizada com 25 pacientes maiores de 18 anos, lúcidos, orientados, alfabetizados, com diagnóstico de síndrome coronariana aguda. Aplicou-se questionário relacionado às informações sociodemográficas e clínicas e a escala The Environmental Stressor Questionnaire. Os dados foram analisados através de estatística descritiva simples. Resultados: houve predominância do sexo masculino (16-64%), com idade de 60 a 70 anos (14-56%). O infarto agudo do miocárdio (14-56%%) foi a causa mais prevalente de internação. As afirmativas “sentir dor” (17-68%); seguido de “não conseguir mexer mãos ou braços devido às vias intravenosas” (13-52%); “não ter controle de si mesmo” (11-44%) e “não ter explicações sobre o tratamento” (10-40%) sobressaíram como extremamente estressantes. Conclusão: conhecer os estressores mais prevalentes contribui para o planejamento do cuidado de enfermagem com ênfase no acolhimento e atendimento às necessidades individualizadas.

Lichens are classified into different functional groups depending on their ecological and physiological response to a given environmental stressor. However, knowledge on lichen response to the synergistic effect of multiple environmental factors is extremely scarce, although vital to get a comprehensive understanding of the effects of global change. We exposed six lichen species belonging to different functional groups to the combined effects of two nitrogen (N) doses and direct sunlight involving both high temperatures and ultraviolet (UV) radiation for 58 days. Irrespective of their functional group, all species showed a homogenous response to N with cumulative, detrimental effects and an inability to recover following sunlight, UV exposure. Moreover, solar radiation made a tolerant species more prone to N pollution’s effects. Our results draw attention to the combined effects of global change and other environmental drivers on canopy defoliation and tree death, with consequences for the protection of ecosystems.

The behaviour of a nursing dam influences the development, physiology, and behaviour of her offspring. Maternal behaviours can be modulated both by environmental factors, including diet, and by physical or behavioural characteristics of the offspring. In most studies of the effects of the environment on maternal behaviour, F0dams nurse their own F1offspring. Because the F1are indirectly exposed to the environmental stressorin uteroin these studies, it is not possible to differentiate between effects on maternal behaviour from direct exposure of the dam and those mediated by changes in the F1as a consequence ofin uteroexposure. In this study, we used a mouse model of high-fat (HF) diet feeding, which has been shown to influence maternal behaviours, combined with cross-fostering to discriminate between these effects. We tested whether the diet of the F0dam or the exposure experienced by the F1pupsin uterois the most significant predictor of maternal behaviour. Neither factor significantly influenced pup retrieval behaviours. However, strikingly, F1in uteroexposure was a significant predictor of maternal behaviour in the 15 min immediately following pup retrieval while F0diet had no discernable effect. Our findings suggest thatin uteroexposure to HF diet programmes physiological changes in the offspring which influence the maternal behaviours of their dam after birth.

The non-ionized form of ammonia is very toxic to many aquatic species. It is especially important in several aspects of fish biology. A large range of organismal strategies for coping with environmental stressors is usually observed in living organisms. Among those, the responses for managing chemical stressors are well studied. The present work compares biochemical responses of two evolutionarily close species, Hoplias malabaricus and Hoplerythrinus unitaeniatus, exposed to environmental ammonia. Adult fish were submitted to 1.0 mg/L of ammonium chloride for 24 hours, and plasma ammonia and urea levels were determined. The activities of OUC enzymes OCT and ARG, and the accessory enzyme GS, were quantified in liver extract and are expressed below in mumol/min/mg of wet tissue. Increases in OUC enzymes (GS from 1.14 to 2.43, OCT from 0.81 to 1.72, and ARG from 3.15 to 4.23), plasma ammonia (from 0.95 to 1.42 mmol/L), and plasma urea (from 0.82 to 1.53 mmol/L) were observed (p < 0.05) in H. malabaricus exposed to 1 mg/L of ammonia chloride. The GS in H. unitaeniatus increased from 1.43 to 1.84, however the OCT, ARG, and plasma urea from H. unitaeniatus did not change. These data indicate that each species responds differently to the same environmental stressor.

BackgroundWildfires are increasingly a significant source of fine particulate matter (PM2.5), which has been linked to adverse health effects and increased mortality. ESKD patients are potentially susceptible to this environmental stressor.MethodsWe conducted a retrospective time-series analysis of the association between daily exposure to wildfire PM2.5 and mortality in 253 counties near a major wildfire between 2008 and 2012. Using quasi-Poisson regression models, we estimated rate ratios (RRs) for all-cause mortality on the day of exposure and up to 30 days following exposure, adjusted for background PM2.5, day of week, seasonality, and heat. We stratified the analysis by causes of death (cardiac, vascular, infectious, or other) and place of death (clinical or nonclinical setting) for differential PM2.5 exposure and outcome classification.ResultsWe found 48,454 deaths matched to the 253 counties. A 10-μg/m3 increase in wildfire PM2.5 associated with a 4% increase in all-cause mortality on the same day (RR, 1.04; 95% confidence interval [95% CI], 1.01 to 1.07) and 7% increase cumulatively over 30 days following exposure (RR, 1.07; 95% CI, 1.01 to 1.12). Risk was elevated following exposure for deaths occurring in nonclinical settings (RR, 1.07; 95% CI, 1.02 to 1.12), suggesting modification of exposure by place of death. “Other” deaths (those not attributed to cardiac, vascular, or infectious causes) accounted for the largest portion of deaths and had a strong same-day effect (RR, 1.08; 95% CI, 1.03 to 1.12) and cumulative effect over the 30-day period. On days with a wildfire PM2.5 contribution >10 μg/m3, exposure accounted for 8.4% of mortality.ConclusionsWildfire smoke exposure was positively associated with all-cause mortality among patients receiving in-center hemodialysis.
