Mental health surveillance in elite Para athletes: early identification and follow-up of athletes at risk of mental health problems.

OBJECTIVE: There is a lack of prospective data on mental health of elite Para athletes. The objective was to identify and follow elite Para athletes at risk of mental health problems. METHODS: In a 124-week prospective cohort study, mental health of German elite Para athletes was monitored using the Patient Health Questionnaire-4 (PHQ-4). In case of positive screening (PHQ-4≥5) over 2 weeks, a follow-up contact was conducted by a sports psychiatrist, who asked the athletes about their mental condition and sources for their mental distress and offered support. RESULTS: 7543 PHQ-4 scores were obtained from 122 Para athletes with a mean weekly response rate of 84%. The PHQ-4 screening was considered positive for symptoms of depression or anxiety with a prevalence of 6.7%, affecting 48.4% (n=59) of all participants at some point during the study period. In 76.6% (n=49) of all follow-up contacts, athletes (n=34) reported at least one mental health problem, most frequently mental distress (n=31), followed by symptoms of depression (n=19) including acute suicidality (n=1). The most common mental stressors cited were related to education and problems with the team, coaches or federation. At follow-up, almost two-thirds of the athletes were either already in professional psychiatric or psychological care (25%) or were recommended to seek such care (32.8%). CONCLUSION: Our screening and follow-up system revealed high rates of mental health problems in elite Para athletes. Programmes for early identification with mental health monitoring under the supervision of mental health professionals should be considered by sports federations for Para athletes.

Heat-related risk at Paris 2024: a proposal for classification and review of International Federations policies.

Several International Federations (IFs) employ specific policies to protect athletes' health from the danger of heat. Most policies rely on the measurement of thermal indices such as the Wet Bulb Globe Temperature (WBGT) to estimate the risk of heat-related illness. This review summarises the policies implemented by the 32 IFs of the 45 sports included in the Paris 2024 Olympic Games. It provides details into the venue type, measured parameters, used thermal indices, measurement procedures, mitigation strategies and specifies whether the policy is a recommendation or a requirement. Additionally, a categorisation of sports' heat stress risk is proposed. Among the 15 sports identified as high, very high or extreme risk, one did not have a heat policy, three did not specify any parameter measurement, one relied on water temperature, two on air temperature and relative humidity, seven on WBGT (six measured on-site and one estimated) and one on the Heat Stress Index. However, indices currently used in sports have been developed for soldiers or workers and may not adequately reflect the thermal strain endured by athletes. Notably, they do not account for the athletes' high metabolic heat production and their level of acclimation. It is, therefore, worthwhile listing the relevance of the thermal indices used by IFs to quantify the risk of heat stress, and in the near future, develop an index adapted to the specific needs of athletes.

Sleep, Health Outcomes and Body Weight (SHOW) study: a measurement burst design study on sleep and risk factors for obesity in black emerging adults in North Carolina, USA.

INTRODUCTION: Black emerging adults (18-28 years) have the highest risk of short sleep duration and obesity. This increased risk may be partly explained by greater stress levels, which may result from race-related stress (racial discrimination and heightened race-related vigilance) or living in more disadvantaged home and neighbourhood environments. Insufficient sleep may also impact obesity risk via several weight-related mechanisms including energy balance, appetite and food reward, cortisol profiles and hydration status. This paper describes the rationale, design and methods for the Sleep, Health Outcomes and Body Weight (SHOW) study. This study aims to prospectively assess the effects of sleep, race-related stress and home/neighbourhood environments on weight-related mechanisms and obesity markers (body weight, waist circumference and fat mass) in 150 black emerging adults. METHODS AND ANALYSIS: The SHOW study follows a measurement burst design that includes 3, 7-day data collection bursts (baseline, 6-month and 12-month follow-ups). Sleep is measured with three methods: sleep diary, actigraphy and polysomnography. Energy balance over 7 days is based on resting and postprandial energy expenditure measured via indirect calorimetry, physical activity via accelerometry and self-reported and ad libitum energy intake methods. Self-reported methods and blood biomarkers assess fasting and postprandial appetite profiles and a behavioural-choice task measures food reward. Cortisol awakening response and diurnal cortisol profiles over 3 days are assessed via saliva samples and chronic cortisol exposure via a hair sample. Hydration markers are assessed with 24-hour urine collection over 3 days and fasting blood biomarkers. Race-related stress is self-reported over 7 days. Home and neighbourhood environments (via the Windshield Survey) is observer assessed. ETHICS AND DISSEMINATION: Ethics approval was granted by the University of North Carolina at Greensboro's Institutional Review Board. Study findings will be disseminated through peer-reviewed publications, presentations at scientific meetings and reports, briefs/infographics for lay and community audiences.

The Birth and Beyond (BABY) study: protocol for a birth cohort study investigating the social and environmental determinants of pregnancy-related outcomes in Black American families.

INTRODUCTION: In the USA, Black birthing people and infants experience disproportionately worse pregnancy-related health outcomes. The causes for these disparities are unknown, but evidence suggests that they are likely socially and environmentally based. Efforts to identify the determinants of these racial disparities are urgently needed to elucidate the highest priority targets for intervention. The Birth and Beyond (BABY) study evaluates how micro-level (eg, interpersonal and family) and macro-level (eg, neighbourhood and environmental) risk and resiliency factors transact to shape birth person-infant health, and underlying psychobiological mechanisms. METHODS AND ANALYSIS: The BABY study will follow 350 Black families (birthing parents, non-birthing parents and infants) from pregnancy through the first postpartum year, with research visits during pregnancy and at infant ages 6 and 12 months. Research visits comprise a combination of interview about a range of recent and life course stress and resiliency exposures and supports, psychophysiological (sympathetic, parasympathetic and adrenocortical) assessment and behavioural observations of parent-infant coregulatory behaviours. Spatial analyses are completed by mapping parent current and past residential addresses onto archival public data (eg, about neighbourhood quality and racial segregation). Finally, EMRs are abstracted for information about birthing parent relevant medical history, pregnancy conditions and infant birth outcomes. Analyses will evaluate the risk and resiliency mechanisms that contribute to pregnancy and birth-related outcomes for Black birthing people and their infants, and the protective role of individual, familial, cultural, and community supports. ETHICS AND DISSEMINATION: The BABY study has been approved by the Institutional Review Board at Albany Medical Centre. The study team consulted with local organisations and groups comprised of stakeholders and community leaders and continues to do so throughout the study. Research results will be disseminated with the scientific and local community as appropriate.

Effectiveness of stress management interventions for nursing students: A systematic review and meta-analysis.

Elevated stress levels are related to diminished mental health, potentially leading to decreased well-being and performance of nursing students. While researchers have focused on developing stress management interventions, there is a need to synthesize the evidence. A systematic review with meta-analysis was conducted to assess the evidence for the effectiveness of stress management interventions in nursing students. A systematic literature search identified controlled stress management interventions employing a validated psychological or physiological stress measure. Forty-one studies were included, with 36 forming a pool of 2715 participants in the meta-analysis. The overall effect on psychological stress was positive. Intervention type, delivery modality, intervention duration in weeks, and number of sessions were moderators of intervention effectiveness, with more significant effects for mind-body programs, on-site delivery methods, durations of 9-12 weeks, and 15-30 sessions. For physiological stress, the biomarkers of blood pressure, heart rate, and cortisol levels decreased significantly. Future research is necessary for promising outcomes related to currently underrepresented indicators and to investigate the long-term effects of interventions.

Effects of cannabidiol on psychosocial stress, situational anxiety and nausea in a virtual reality environment: a protocol for a single-centre randomised clinical trial.

INTRODUCTION: The non-intoxicating plant-derived cannabinoid, cannabidiol (CBD), has demonstrated therapeutic potential in a number of clinical conditions. Most successful clinical trials have used relatively high (≥300 mg) oral doses of CBD. Relatively few studies have investigated the efficacy of lower (<300 mg) oral doses, typical of those available in over-the-counter CBD products. METHODS: We present a protocol for a randomised, double-blind, placebo-controlled, parallel-group clinical trial investigating the effects of a low oral dose (150 mg) of CBD on acute psychosocial stress, situational anxiety, motion sickness and cybersickness in healthy individuals. Participants (n=74) will receive 150 mg of CBD or a matched placebo 90 min before completing three virtual reality (VR) challenges (tasks) designed to induce transient stress and motion sickness: (a) a 15 min 'Public Speaking' task; (b) a 5 min 'Walk the Plank' task (above a sheer drop); and (c) a 5 min 'Rollercoaster Ride' task. The primary outcomes will be self-reported stress and nausea measured on 100 mm Visual Analogue Scales. Secondary outcomes will include salivary cortisol concentrations, skin conductance, heart rate and vomiting episodes (if any). Statistical analyses will test the hypothesis that CBD reduces nausea and attenuates subjective, endocrine and physiological responses to stress compared with placebo. This study will indicate whether low-dose oral CBD has positive effects in reducing acute psychosocial stress, situational anxiety, motion sickness and cybersickness. ETHICS AND DISSEMINATION: The University of Sydney Human Research Ethics Committee has granted approval (2023/307, version 1.6, 16 February 2024). Study findings will be disseminated in a peer-reviewed journal and at academic conferences. TRIAL REGISTRATION NUMBER: Australian New Zealand Clinical Trials Registry (ACTRN12623000872639).

Metabolic Adaptation and Cellular Stress Response As Targets for Cancer Therapy.

Cancer cells, which divide indefinitely and without control, are frequently exposed to various stress factors but manage to adapt and survive. The mechanisms by which cancer cells maintain cellular homeostasis and exploit stress conditions are not yet clear. Here, we elucidate the roles of diverse cellular metabolism and its regulatory mechanisms, highlighting the essential role of metabolism in cellular composition and signal transduction. Cells respond to various stresses, including DNA damage, energy stress, and oxidative stress, thereby causing metabolic alteration. We provide profound insight into the adaptive mechanisms employed by cancer cells to ensure their survival among internal and external stressors through a comprehensive analysis of the correlation between metabolic alterations and cellular stress. Furthermore, this research establishes a robust framework for the development of innovative therapeutic strategies that specifically target the cellular adaptations of cancer cells.

Efecto del estrés agudo y de la variación del estímulo masticatorio sobre el dolor nociceptivo somático en un modelo murino

Introducción. El estrés agudo se relaciona con la enérgica liberación de catecolaminas, citoquinas y cortisol, las cuales afectan la percepción dolorosa. La masticación estimula neuronas serotoninérgicas, dichas neuronas modulan a las vías neurales del dolor; sin embargo, la relación entre dichas variables aún está en proceso de entendimiento. Objetivo. Determinar el efecto del estrés agudo y del estímulo masticatorio sobre el dolor. Métodos. Experimento que se desarrolló en el bioterio de la Facultad de Medicina de la UNMSM. 40 ratones Balb/c machos de 8 semanas de edad. Los ratones fueron asignados aleatoriamente en 5 grupos iguales. A: semana 1 sin ningún estímulo y semana 2 estimulo masticatorio + estrés. B: semana 1 sin ningún estímulo y semana 2 estrés. C: semana 1 estrés y semana 2 sin ningún estímulo. D: semana 1 estímulo masticatorio + estrés y semana 2 sin ningún estímulo. E: control, sin ningún estimulo. El dolor se evaluó en los 5 grupos a los 7 y 14 días mediante la prueba de tiempo de retirada de la cola ante estímulo térmico. Resultados. Se empleó la prueba de ANOVA para la evaluación intergrupo, no hallándose diferencia significativa. Mediante la prueba de t student para muestras relacionadas se hizo la evaluación intragrupo donde se encontró diferencia significativa entre los 7 vs los 14 días tanto en el grupo A (p=0,029) como en el grupo C (p=0,03). Conclusión. El efecto del estrés agudo sobre la percepción dolorosa fue disminuida por el estímulo masticatorio en ratones Balb/c.

Introduction. Acute stress is related to the energetic release of catecholamines, cytokines, and cortisol, which trigger pain perception. Chewing stimulates serotonergic neurons, these neurons modulate the neural pathways of pain; however, the relationship between these variables is still in the process of understanding. Objective. To determine the effect of acute stress and chewing stimulus on pain. Methods. an experiment that was developed in the Faculty of Medicine of the UNMSM. 40 eight-week-old male Balb/c mice were randomly assigned into 5 equal groups. A: week 1 without any stimulus and week 2 chewing stimulus + stress. B: week 1 without any stimulus and week 2 stress. C: week 1 stress and week 2 without any stimulus. D: week 1 masticatory stimulus + stress and week 2 without any stimulus. E: control, without any stimulus. Pain was assessed in the 5 groups at 7 and 14 days using the tail-withdrawal time test before thermal stimulation. Results. The ANOVA test was used for the intergroup evaluation, finding no significant difference. Using the t student test for related samples, the intragroup evaluation was made, where a significant difference was found between 7 vs. 14 days, both in group A (p=0.029) and in group C (p=0.03). Conclusion. The effect of acute stress on pain perception was decreased by chewing stimulus in Balb/c mice.

Changes in Physiological Indices Before and After Nursing Care of Postoperative Patients With Esophageal Cancer in the ICU.

Introduction: Various stressors have been identified in patients in the intensive care unit (ICU), including postoperative pain, ventilatory management, and nursing care. However, sedated patients are less responsive, and nurses have difficulty capturing their stressors. Objective: To investigate patient stress caused by nursing care performed in the ICU on sedated patients based on changes in physiological indices. Methods: We observed nursing care performed on patients with postoperative esophageal cancer under sedation in the ICU. This included endotracheal suctioning and turning, the time required for the care, and the patients' behavioral responses. Information on arousal levels, autonomic nervous system indices, and vital signs were also obtained. The changes in indicators before and after care were then compared and analyzed. Results: There were 14 patients in the study. The mean age of the patients was 68 years. Ninety-nine scenes of nursing care were observed, and in six of these, additional bolus sedation was administered because of the patient's significant body movements. In endotracheal suctioning, no significant changes were observed in all indicators. In turning, vital signs changed significantly, and when both were continued, all indicators changed significantly. Conclusion: Our study found that different types and combinations of nursing care may cause different stresses to the patients. Moreover, the autonomic nervous system indices may be more likely to react to stresses in a variety of nursing care, while arousal levels may be more likely to react to burdensome stresses. If the characteristics of these physiological indicators can be understood and effectively utilized during care, it may be possible to better identify and reduce patient stress during sedation management.

The Effect of Body Relaxation Techniques on Pre-Eclampsia Syndrome.

Background: Hypertension in the second trimester of pregnancy is accompanied by proteinuria that is called Preeclampsia Syndrome (PES). Body relaxation is a technique which makes harmony between mind and body. The aim of this study was to investigate the effect of Body Relaxation Technique (BRT) on some symptoms of Preeclampsia Syndrome (PES). Materials and Methods: This clinical trial was conducted on 96 high-risk pregnant women who were selected by random sampling method from among women referring to community health centers of Isfahan city. The samples were divided into intervention and control groups by even and odd numbers. The intervention group members received BRT during 16 sessions. Blood pressure and proteinuria were measured and recorded before and after the intervention in both groups at the beginning and in the 36th week of pregnancy. The collected data were analyzed. Result: According to the Chi-square test, the frequency of PES was 11.10% and 23.50% in the intervention and control groups, respectively (χ2 = 3.95, df = 1, p = 0.046). After the intervention, there was no significant difference between the two groups in terms of the diastolic blood pressure and proteinuria. Systolic blood pressure and stress were also significantly reduced in the intervention group. However, proteinuria was not significantly different between the two groups. Conclusions: Based on the results, the relaxation technique, as an easy technique, is recommended for pregnant women who are susceptible to pregnancy hypertension and preeclampsia. Moreover, as a clinical complementary method, it can be recommended for preventing the symptoms of PES.

Efecto del estímulo masticatorio y estrés agudo sobre la interleuquina 6, la memoria y el aprendizaje espacial en ratones Balb/c

Introducción. El estrés agudo altera la memoria y aprendizaje espacial y la expresión de la interleuquina 6 (IL-6), mientras que el estímulo masticatorio evitaría dichos efectos. Objetivo. Determinar el efecto del estímulo masticatorio y el estrés agudo sobre la expresión de interleuquina 6, la memoria y el aprendizaje espacial en ratones. Métodos. Experimento con 70 ratones albinos machos de 2 meses de edad de la cepa Balb/c que fueron distribuidos aleatoriamente en grupo A1: estrés agudo 1 hora; grupo A2: estrés agudo 1 hora + estímulo masticatorio 1 hora; grupo B1: estrés agudo 2 horas; grupo B2: estrés agudo 2 horas + estímulo masticatorio 2 horas; grupo C1: estrés agudo 3 horas; grupo C2: estrés agudo 3 horas + estímulo masticatorio 3 horas; y grupo D: sin intervención. Durante 3 días, se evaluó la memoria y el aprendizaje espacial en el laberinto acuático de Morris. La IL-6 fue determinada mediante ELISA. Resultados. La IL-6 fue mayor en el grupo B2 vs los demás grupos (p < 0,001). Además, en el primer día de evaluación, la adquisición de memoria y aprendizaje espacial fue menor en el grupo A1 vs A2 (p = 0,042). Conclusión. Solo en el primer día de evaluación encontramos que el estímulo masticatorio previno la disminución de la adquisición de memoria y aprendizaje espacial en ratones sometidos a estrés agudo de baja intensidad. Los resultados en general no fueron concluyentes sobre el efecto del estímulo masticatorio. Además, la IL-6 fue mayor en el estrés + el estímulo masticatorio (grupo B2) sobre el resto.

Introduction. Acute stress alters memory and spatial learning and the expression of interleukin 6, the chewing stimulus would prevent these effects. Objective. To determine the effect of chewing stimulation and acute stress on the expression of interleukin 6 and memory and spatial learning in mice. Methods. Experiment where 70 male albino mice of the Balb/c of age 2 month were randomly distributed into: Group A1: acute stress 1 hour; Group A2: acute stress 1 hour + chewing stimulus 1 hour; Group B1: acute stress 2 hours; Group B2: acute stress 2 hours + chewing stimulus 2 hours; Group C1: acute stress 3 hours; C2: acute stress 3 hours + chewing stimulus 3 hours; Group D: without intervention. For 3 days, spatial memory and learning were tested in the Morris water maze. Interleukin 6 (IL-6) was analyzed by ELISA test. Results. IL-6 was higher in the B2 group vs the other groups (p<0.0001). In addition, on the first day of evaluation, the acquisition of spatial memory and spatial was lower in the A1 vs. A2 group (p=0.042). Conclusión. Only on the first day of evaluation, we found that the masticatory stimulus prevented the decrease in memory acquisition and spatial learning in mice subjected to low-intensity acute stress. The results were generally inconclusive on the effect of masticatory stimulation. In addition, IL-6 was higher in the stress + masticatory stimulus (group B2) over the rest.

Effectiveness of physical activity interventions for improving depression, anxiety and distress: an overview of systematic reviews.

OBJECTIVE: To synthesise the evidence on the effects of physical activity on symptoms of depression, anxiety and psychological distress in adult populations. DESIGN: Umbrella review. DATA SOURCES: Twelve electronic databases were searched for eligible studies published from inception to 1 January 2022. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Systematic reviews with meta-analyses of randomised controlled trials designed to increase physical activity in an adult population and that assessed depression, anxiety or psychological distress were eligible. Study selection was undertaken in duplicate by two independent reviewers. RESULTS: Ninety-seven reviews (1039 trials and 128 119 participants) were included. Populations included healthy adults, people with mental health disorders and people with various chronic diseases. Most reviews (n=77) had a critically low A MeaSurement Tool to Assess systematic Reviews score. Physical activity had medium effects on depression (median effect size=-0.43, IQR=-0.66 to -0.27), anxiety (median effect size=-0.42, IQR=-0.66 to -0.26) and psychological distress (effect size=-0.60, 95% CI -0.78 to -0.42), compared with usual care across all populations. The largest benefits were seen in people with depression, HIV and kidney disease, in pregnant and postpartum women, and in healthy individuals. Higher intensity physical activity was associated with greater improvements in symptoms. Effectiveness of physical activity interventions diminished with longer duration interventions. CONCLUSION AND RELEVANCE: Physical activity is highly beneficial for improving symptoms of depression, anxiety and distress across a wide range of adult populations, including the general population, people with diagnosed mental health disorders and people with chronic disease. Physical activity should be a mainstay approach in the management of depression, anxiety and psychological distress. PROSPERO REGISTRATION NUMBER: CRD42021292710.

Stress hyperglycemia ratio predicts the outcome of successful recanalization after endovascular treatment in patients with acute ischemic stroke / 国际脑血管病杂志

Objective:To investigate the correlation between stress hyperglycemia ratio (SHR) and poor outcome of successful recanalization after endovascular treatment in patients with acute ischemic stroke.Methods:From January 2019 to October 2022, patients with acute ischemic stroke received endovascular treatment and successful recanalization in the Second People’s Hospital of Lianyungang were included retrospectively. SHR was defined as the fasting blood sugar and glycosylated hemoglobin ratio. At 90 d after procedure, the outcome of patients was evaluated using the modified Rankin Scale score. 0-3 was defined as good outcome, and >3 was defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent risk factor for poor outcome. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of SHR for 90 d poor outcome in patients with successful recanalization after endovascular treatment.Results:A total of 159 patients were enrolled, including 98 males (61.6%), aged 69.8±8.9 years old. The baseline National Institutes of Health Stroke Scale (NIHSS) score was 12.6±4.3, and SHR was 1.17±0.46. One hundred and five patients (66.0%) had good outcome, while 54 (34.0%) had poor outcome. There were statistically significant differences in SHR, fasting blood glucose, glycosylated hemoglobin, baseline NIHSS score and the proportion of patients with poor collateral circulation and symptomatic intracranial hemorrhage between the poor outcome group and the good outcome group (all P<0.05). Multivariate logistic regression analysis showed that SHR was an independent predictor of poor outcome (odds ratio 2.254, 95% confidence interval 1.136-4.278; P<0.001). The ROC curve analysis showed that the area under the curve of SHR for predicting poor outcome was 0.726 (95% confidence interval 0.648-0.804; P<0.001), which was higher than fasting blood glucose and glycosylated hemoglobin. The optimal cutoff value for SHR was 1.21, and the sensitivity and specificity for predicting poor outcomes were 66.23% and 75.82%, respectively. Conclusion:SHR is associated with the poor outcome of successful recanalization after endovascular treatment in patients with acute ischemic stroke and can be used as a potential predictor.

Introduction: COVID-19 has been a considerable challenge to obtain high-quality training for students in the Nursing area because universities continued with norms, outdated strategies that did not respond to changes. Objective: to analyse the characteristics of academic stress in Nursing students during the teaching-learning process in times of the COVID-19 pandemic. Methods: a systematic bibliographic review was carried out to develop a reflective critical analysis on the content of the bibliographies, with a documentary search based on the 32 previously selected original scientific articles, publications in English, Spanish and Portuguese in the Scopus databases, Pubmed, Dialnet, Scielo, Elsevier, Latindex, and Web of Science. The keywords used were stress, academy, resilience, pandemic, and virtual teaching. Development: the change from the face-to-face to the virtual environment caused a significant shift in the development of the teaching-learning mode, generating stress, for which reason care protocols for students must be managed. Conclusions: the academy was surprised by the pandemic, as it happened with the general population. Not enough strategies were articulated to be able to face the different situations that generated academic stress. Resilience needs to be addressed for all health eventualities.

Method: It was planned with a descriptive and relational screening design. It was carried out with the participation of 132 patients diagnosed with COPD. The study data were collected through Patient Information Form, Perceived Stress Scale, and Death Anxiety Scale. Descriptive statistics and multiple regression analysis were used in data analysis. Results: The COPD patients' total perceived stress scale and perceived insufficient self-efficacy and perceived stress/distress subscale mean scores were found as 32.75 ± 5.32, 15.81 ± 3.60, and 16.93 ± 2.97, respectively. The patients' Anxiety total scale mean score was determined to be 6.96 ± 3.40. A positive and statistically significant relationship was found between COPD patients' Perceived Stress total scale mean score and their Death Anxiety Scale mean score (F = 4.332, p < 0.05). Conclusion: Perceived stress level of COPD patients was found to be at a high level, while their death anxiety level was determined as moderate. It was also determined that as perceived stress levels of the patients increased, their death anxiety levels also increased.

RESUMEN Objetivos: Investigar la relación entre el nivel de estrés percibido y la ansiedad ante la muerte en personas con EPOC. Método: Se planificó con un diseño de screening descriptivo y relacional. En el estudio participaron 132 pacientes diagnosticados de EPOC. Los datos del estudio se recopilaron mediante el Formulario de información del paciente, la Escala de estrés percibido y la Escala de ansiedad ante la muerte. En el análisis de datos se utilizaron estadísticas descriptivas y análisis de regresión múltiple. Resultados: Las puntuaciones medias de la escala total de estrés percibido de los pacientes con EPOC y de la autoeficacia percibida insuficiente y de la subescala de estrés/angustia percibida fueron 32.75±5.32, 15.81±3.60 y 16.93±2.97 respectivamente. Se determinó que la puntuación media de la escala total de Ansiedad de los pacientes era 6.96 ± 3.40. Se encontró una relación positiva y estadísticamente significativa entre la puntuación media de la escala total de Estrés Percibido de los pacientes con EPOC y la puntuación media de la Escala de Ansiedad ante la Muerte (F = 4.332, p <0.05). Conclusión: Se descubrió que el nivel de estrés percibido por los pacientes con EPOC era alto, mientras que se determinó que su nivel de ansiedad ante la muerte era moderado. También se determinó que a medida que aumentaban los niveles de estrés percibido de los pacientes, también aumentaban sus niveles de ansiedad ante la muerte.

RESUMO Objetivos: Objetivou-se investigar a relação entre nível de estresse percebido e ansiedade de morte em indivíduos com DPOC. Método: Foi planejado com design de triagem descritiva e relacional. Foi realizado com a participação de 132 pacientes diagnosticados com DPOC. Os dados do estudo foram coletados por meio da Ficha de Informações do Paciente, da Escala de Estresse Percebido e da Escala de Ansiedade de Morte. Estatísticas descritivas e análises de regressão múltipla foram utilizadas na análise dos dados. Resultados: Os escores médios da escala total de estresse percebido e autoeficácia percebida insuficiente e estresse/angústia percebida dos pacientes com DPOC foram de 32.75 ± 5.32, 15.81 ± 3.60 e 16.93 ± 2.97, respectivamente. A pontuação média da escala total de ansiedade dos pacientes foi determinada em 6.96±3.40. Foi encontrada uma relação positiva e estatisticamente significativa entre a pontuação média da escala total de Estresse Percebido dos pacientes com DPOC e a pontuação média da Escala de Ansiedade da Morte (F = 4.332, p < 0.05). Conclusão: O nível de estresse percebido dos pacientes com DPOC foi considerado alto, enquanto o nível de ansiedade de morte foi considerado moderado. Também foi determinado que, à medida que os níveis de estresse percebidos pelos pacientes aumentavam, os níveis de ansiedade de morte também aumentavam.
