Screening and detection of delirium in an adult critical care setting: a best practice implementation project.

Aim: To assess compliance with evidence-based practice regarding screening and detection of delirium in adult patients at the ICU from a university hospital.

Methods: The compliance rates were evaluated using the Joanna Briggs Institute Practical Application of Clinical Evidence System and Getting Research into Practice audit and feedback tool. This strategy was designed in three phases: (1) establishing a team and conducting a baseline audit based on criteria informed by the evidence; (2) reflecting on the results of the baseline audit and designing and implementing strategies to address noncompliance found in the baseline audit informed by the JBI Getting Research into Practice framework; and (3) conducting a follow-up audit to assess the outcomes of the interventions implemented to improve practice and identify future practice issues to be addressed in subsequent audits.

The effectiveness of Chair Massage on Stress and Pain in Oncology.

Background: There is a high prevalence of moderate-to-high levels of chronic stress among nurses, as well as an occurrence of musculoskeletal disorders.

Purpose: To evaluate the effectiveness of chair massage to reduce chronic stress and musculoskeletal pain in the Oncology Nursing team.

Setting: Two teaching cancer hospitals, one public and the other private, in São Paulo city, Brazil.

Cortisol reactivity to a psychosocial stressor significantly increases the risk of developing Cognitive Impairment no Dementia five years later.

Alzheimer's disease (AD) patients show high cortisol levels suggesting that biological mediators of stress may play a role in the neurodegenerative process of cognitive disorders. However, there is no consensus as to whether cortisol concentrations represent a risk factor for the development of cognitive impairment. We analyzed the potential association between the incidence of cognitive impairment and cortisol concentrations under basal and acute stress conditions in 129 individuals aged 50 years or older, with preserved cognitive and functional abilities.

Work-related stress and cognitive performance among middle-aged adults: The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Assessing risk factors exposure, such as stress in the workplace during adulthood, may contribute to detecting early signs of cognitive impairment in order to implement effective actions to improve brain health and consequently to decrease cognitive disorders later in life. In this cross-sectional study, we aimed to investigate whether work-related stress is associated with low cognitive performance in middle-aged adults from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) and whether social support mediates this relationship. Work-related stress was evaluated in 9,969 workers using the Demand-Control-Support Questionnaire.

Dementia and Cognitive Impairment Prevalence and Associated Factors in Indigenous Populations: A Systematic Review.

Population aging has been accompanied by worldwide growth in dementia. However, little is known about the prevalence of dementia and cognitive impairment not dementia in ethnically diverse populations, such as indigenous populations conceptualized as groups of persons who self-identify as indigenous and who are recognized as distinctive communities reproducing ancestral, historical, and territorial culture. This is particularly relevant in view of increasing life expectancy in indigenous populations and, consequently, in the number of elderly people, as well as the changes in their multimorbidity profile.

[Subjective memory complain in healthy elderly: influence of depressive symptoms, perceived stress and self-esteem].

The current study analyzed the relationship between perceived stress, depressive symptoms and self-esteem in elderly with and without subjective memory complain. Two-hundred four elderly were included (104 without and 100 with subjective memory complain) assesse using the Memory Assessment Complain Questionnaire (MAC-Q). The study protocol was composed by the Perceived Stress Scale (PSS), the Geriatric Depression Scale (GDS) and the Self-Esteem Scale of Rosenberg (SES).

Peripheral oxidative stress biomarkers in mild cognitive impairment and Alzheimer's disease.

Oxidative stress has been associated with normal aging and Alzheimer's disease (AD). However, little is known about oxidative stress in mild cognitive impairment (MCI) patients who present a high risk for developing AD. The aim of this study was to investigate plasma production of the lipid peroxidation marker, malonaldehyde (MDA) and to determine, in erythrocytes, the enzymatic antioxidant activity of catalase, glutathione peroxidase (GPx), glutathione reductase (GR), and glutathione S-transferase (GST) in 33 individuals with MCI, 29 with mild probable AD and 26 healthy aged subjects.

Effects of stress hormones on the brain and cognition: Evidence from normal to pathological aging.

Several studies have demonstrated a wide cognitive variability among aged individuals. One factor thought to be associated with this heterogeneity is exposure to chronic stress throughout life. Animal and human evidence demonstrates that glucocorticoids (GCs), the main class of stress hormones, are strongly linked to memory performance whereby elevated GC levels are associated with memory performance decline in both normal and pathological cognitive aging.

[Stress symptoms and coping strategies in healthy elderly subjects].

Elderly subjects may present stress symptoms due to physical, psychological and social changes during aging process. The aim of this study was to identify stress symptoms in elderly subjects and the coping strategies they used, verifying the relationship between these variables. The Stress Symptoms List (SSL) and the Jalowiec Coping Scale were administered to 41 healthy elderly subjects.

Stress and coping in older people with Alzheimer's disease.

Aim: To investigate stress intensity and coping style in older people with mild Alzheimer's disease.

Background: The potential risk assessment of a stress event and the devising of coping strategies are dependent on cognitive function. Although older individuals with Alzheimer's disease present significant cognitive impairment, little is known about how these individuals experience stress events and select coping strategies in stress situations.

The influence of schooling on working memory performance in elderly individuals without cognitive decline.

Unlabelled: Over recent decades, research on cognition has been developed rapidly toward better understanding the cognitive changes that usually occur during normal aging. There is evidence that elderly individuals have worse working memory performance than young adults. However, the effect of education on this cognitive function remains unclear.
