ABSTRACT

Burnout is most commonly defined as a syndrome characterized by emotional exhaustion, cynicism, and ineffectiveness, which occurs in response to chronic stressors at work. It can adversely affect health workers' physical and mental health, and the quality of care provided. The COVID-19 pandemic increased stressors and could impact burnout prevalence in this group. There is a lack of information regarding the prevalence of burnout among hospital health workers in Brazil. A newer definition of burnout has been proposed that considers three different clinical profiles: the frenetic, underchallenged and worn-out subtypes. This differentiation could lead to interventions tailored for each subtype. The present study aimed to estimate the prevalence of burnout, its subtypes, and associated factors in workers of a public hospital network in Brazil, during the pandemic. A total of 143 randomly selected participants answered an online form that included sociodemographic and occupational items, and the Burnout Clinical Subtypes Questionnaire, a summarized version. This questionnaire evaluates three burnout dimensions (overload, lack of development, neglect) that can be used to discriminate the three burnout subtypes (frenetic, underchallenged, worn-out, respectively); higher scores indicate higher burnout levels. The prevalence of burnout was high (53.85%), similar to other studies during the pandemic. The most common subtypes were 'frenetic' (34.97%), characterized by increased efforts to meet work demands, to the point of neglecting personal needs, and 'lack of development' (23.78%), characterized by a sense that work is uninteresting and does not contribute to personal development, and a perfunctory behavior towards tasks. Age was associated with burnout: workers with less than 51 years presented higher levels of burnout. These findings indicate the need for effective interventions to prevent and/or treat burnout. The assessment of burnout subtypes can allow managers to better understand the processes affecting employees, and inform actions to improve workforce health.

ABSTRACT

OBJECTIVES: Psychological comorbidities have been associated with asthma in adults and children, but have not been studied in a population of children with severe asthma. The aim of this study was to test the hypothesis that symptoms of anxiety or depression are highly prevalent in pediatric severe asthma and negatively effects asthma control. METHODS: Longitudinal assessments of anxiety or depression symptoms (Patient Health Questionnaire-4 [PHQ-4]), asthma control (Asthma Control Test [ACT]), and lung function were performed in a single-center pediatric severe asthma clinic. Participant data were collected during routine clinical care. Primary outcomes were ACT and forced expiratory volume in 1 s per forced vital capacity (FEV1/FVC). RESULTS: Among 43 subjects (with total 93 observations), 58.1% reported at least one anxious or depressive symptom and 18.6% had a PHQ-4 more than 2, the threshold for an abnormal test result. After adjusting for age, sex, race, and asthma medication step, there was a significant reduction in ACT for girls with PHQ-4 more than 2 (adjusted mean [SE] ACT for PHQ-4 > 2: 13.64 [0.59], ACT for PHQ-4 ≤ 2: 20.64 [1.25], p = .02) but not boys. Moreover, there was a significant differential effect of mental health impairment for girls than boys. ACT for girls with PHQ more than 2: 13.64 (0.59) compared with boys with PHQ-4 more than 2: 17.82 (0.95), adjusted mean difference ACT by sex = 4.18 points; 95% confidence interval, 0.63-7.73; p = .033. In adjusted models, there was no association between PHQ-4 more than 2 and FEV1/FVC. CONCLUSIONS: Symptoms of anxiety and depression are common. In children with severe asthma, a PHQ-4 score more than 2 is associated with worse asthma symptom control in girls, but not boys.

ABSTRACT

[reaction: see text] Peptide p-nitroanilides are useful compounds for studying protease activity; however, the poor nucleophilicity of p-nitroaniline makes their preparation difficult. We describe a new efficient approach for the Fmoc-based synthesis of peptide p-nitroanilides using an aryl hydrazine resin. Mild oxidation of the peptide hydrazide resin yields a highly reactive acyl diazene that efficiently reacts with weak nucleophiles. We have prepared several peptide p-nitroanilides, including substrates for the Lethal Factor protease from B. anthracis.
