Hair cortisol and cognitive performance in healthy older people
2013
Summary Worse cognitive performance in older people has been associated with hypothalamic—pituitary—adrenal axis dysregulation (in particular, higher cortisol levels). Analysis of hair cortisol concentrations (HCC) is a novel method to measure long-term cortisol exposure, and its relationship with cognition in healthy older people has not yet been studied. We investigated whether HCC (measured in hair scalp) and diurnal salivary cortisol levels (awakening, 30 min after awakening, and evening, across two days) were related to cognitive performance (assessed with the Trail-making Test A and B, Digit Span Forward and Backward, word list-RAVLT and Stories subtest of the Rivermead) in 57 healthy…
The cortisol awakening response in caregivers of schizophrenic offspring shows sensitivity to patient status
2010
Taking care of offspring during a prolonged period of time is probably one of the most stressful life experiences for parents. The present study compares the cortisol awakening response (CAR) in 38 long-term caregivers (mothers and fathers of schizophrenic relatives) with a control group of 32 non-caregivers. Factors such as general stress, caregiver burden, patient severity, and institutionalization were studied. Although a blunted CAR was observed in caregivers in comparison with controls, this difference was not significant. Among caregivers, the absence of institutionalization for the patient is associated with a lack of CAR in caregivers in comparison with caregivers of institutionally…
Sleep Alterations in Non-demented Older Individuals: The Role of Cortisol
2017
Background: Sleep alterations can impair quality of life and contribute to disease progression but they, and their features and contributing factors, are rarely analysed in institutionalised older individuals. In this study, we investigated sleep alterations, the factors involved, and the role of cortisol in sleep-related problems in institutionalised individuals. Methods: We conducted a descriptive cross-sectional study in participants living in nursing homes in Valencia (Spain); sleep alterations were determined based on two validated tools: the Athens insomnia scale and Oviedo sleep questionnaire. Plasma cortisol was measured in the morning and determined by high performance liquid chrom…
Cortisol awakening response and cognitive performance in hypertensive and normotensive older people.
2016
Healthy older people with a cortisol awakening response (CAR) of decreased magnitude show worse frontal cortex-related cognitive performance. Systemic hypertension has been related to a CAR of decreased magnitude. Additionally, worse executive function and processing speed have been observed in older people with systemic hypertension. This is the first study to examine the relationship between the CAR (measured with six saliva samples at home on two consecutive weekdays) and cognitive performance, in both hypertensive (n=26) and normotensive (n=28) older people (from 56 to 78years old). Hypertensive participants showed lower morning cortisol secretion, and they also woke up earlier. No diff…
The cortisol awakening response and memory performance in older men and women.
2012
Summary The activity and regulation of the hypothalamus-pituitary-adrenal axis has been related to cognitive decline during aging. This study investigated whether the cortisol awakening response (CAR) is related to memory performance among older adults. The sample was composed of 88 participants (44 men and 44 women) from 55 to 77 years old. The memory assessment consisted of two tests measuring declarative memory (a paragraph recall test and a word list learning test) and two tests measuring working memory (a spatial span test and a spatial working memory test). Among those participants who showed the CAR on two consecutive days, we found that a greater CAR was related to poorer declarativ…
Being an optimist or a pessimist and its relationship with morning cortisol release and past life review in healthy older people
2017
Investigate the relationship between optimism and pessimism and the cortisol awakening response (CAR) and past life review in healthy older people.76 older volunteers summarised their lives, highlighting the most important events, impressions and experiences. Cortisol saliva samples were collected on two consecutive weekdays. High and low optimism and pessimism groups were computed by mean split.Percentages of positive (PE) and negative events (NE) and positive (PCE) and negative cognitions and emotions (NCE) were obtained. Optimism and pessimism were measured with the Life Orientation Test Revised. The areas under the curve with respect to the ground and with respect to the increase were c…
Correlation between adrenal function, growth hormone secretion, and insulin sensitivity in children with idiopathic growth hormone deficiency
2017
Purpose Patients with growth hormone deficiency (GHD) demonstrate an increased cortisol/cortisone ratio which could potentially explain the metabolic features of GHD, while GH treatment (GHT) could increase the cortisol metabolism. Methods In 35 children (27 M, mean age 10.1 years) with idiopathic GHD at baseline and after 12 months of GHT and in 25 controls, in addition to metabolic parameters, we assessed adrenal function by morning serum cortisol, its peak, and its area under the curve (AUCCOR) during insulin tolerance test (ITT). Results A cortisol peak <18 µg/dl was shown in 22 and 31% of GHD children at baseline and after GHT, respectively. At baseline, GHD children had lower fasting …
Recovery of rescuers from a 24-h shift and its association with aerobic fitness.
2017
Objectives: Rescuers work in 24-h shifts and the demanding nature of the occupation requires adequate recovery between work shifts. The purpose of this study has been to find out what kind of changes in autonomic control may be seen during work shift and its recovery period in the case of rescuers. An additional interest has been to see if aerobic fitness is associated with recovery from work shifts. Material and Methods: Fourteen male rescuers (aged 34±9 years old) volunteered to participate in the study. Heart rate variability (HRV) was recorded for 96 h to study stress and recovery, from the beginning of a 24-h work shift to the beginning of the next shift. Aerobic fitness assessment inc…
Ks. Konstantego Damrota opowieść o polskim Pomorzu (na podstawie Szkiców z ziemi i historyi Prus Królewskich z 1886 r.)
2022
Jedną z ważnych postaci Kościoła katolickiego na Pomorzu był ks. Konstanty Damrot (1841–1895) – syn śląskiej ziemi, wybitny literat, wieloletni dyrektor katolickiego seminarium nauczycielskiego w Kościerzynie. Zachwycony pięknem dawnych Prus Królewskich, w 1886 r. wydał pozycję książkową zatytułowaną Szkice z ziemi i historyi Prus Królewskich, Jego zamiarem było nie tylko opisanie piękna nadmorskiej krainy, ale przede wszystkim obudzenie ducha polskiego w tamtejszych mieszkańcach. Poprzez słowo pisane chciał także spopularyzować historię i kulturę nadmorskiej krainy, przesiąkniętej polskością, zbudowaną na wierze katolickiej i rodzimej tradycji. Autor w krótkiej syntezie przedstawia biogram…
Timing of Early Maternal Mental Health and Child Cortisol Regulation
2015
Maternal mental health problems can negatively impact children's physiological stress regulation. Yet, little is known of their long-term effects, especially related to the timing of maternal symptoms. We examined how maternal mental health problems during pregnancy versus in the early postpartum period predict children's cortisol levels and diurnal patterns at 10–12 years. Participants were a selection (N = 102) of an original sample of 805 Finnish families, who were followed from the second trimester of pregnancy (T1) to child's age of 2 months (T2) and 12 months (T3), and again at child's age of 10–12 years (T4). Based on the timing of psychological distress and depressive symptoms (T1–T…
