Chronic stress undermines the compensatory sleep efficiency increase in response to sleep restriction in adolescents

To investigate the effects of real‐life stress on the sleep of adolescents, we performed a repeated‐measures study on actigraphic sleep estimates and subjective measures during one regular school week, two stressful examination weeks and a week's holiday. Twenty‐four adolescents aged 17.63 ± 0.10 years (mean ± standard error of the mean) wore actigraphs and completed diaries on subjective stress, fatigue, sleep quality, number of examinations and consumption of caffeine and alcohol for 4 weeks during their final year of secondary school. The resulting almost 500 assessments were analysed using mixed‐effect models to estimate the effects of mere school attendance and additional examination stress on sleep estimates and subjective ratings. Total sleep time decreased from 7:38 h ± 12 min during holidays to 6:40 h ± 12 min during a regular school week. This 13% decrease elicited a partial compensation, as indicated by a 3% increase in sleep efficiency and a 6% decrease in the duration of nocturnal awakenings. During examination weeks total sleep time decreased to 6:23 h ± 8 min, but it was now accompanied by a decrease in sleep efficiency and subjective sleep quality and an increase in wake bout duration. In conclusion, school examination stress affects the sleep of adolescents. The compensatory mechanism of more consolidated sleep, as elicited by the sleep restriction associated with mere school attendance, collapsed during 2 weeks of sustained examination stress.     

An integrative review on family caregivers’ involvement in care of home‐dwelling elderly

Often family members provide care‐giving, which allows older adults to remain in their homes. With declining health and increasing frailty, care‐giving of elderly people becomes a task of family caregivers (FC) in conjunction with home care nurses. It has been shown in both acute care settings and long‐term care facilities that family members prefer to be involved in decision‐making and care planning for their next of kin. Therefore, an integrative review was conducted to explore the body of knowledge of FCs’ involvement in home‐care settings from the FCs’ perspective. CINAHL, PubMed, and Cochrane databases was searched with the terms family caregiver, involvement, home care, and community dwelling. Studies written in German or English between 1996 and 2017 focusing on FCs’ caring for home‐dwelling older adults together with home care nurses were included and critically appraised. The extracted findings were analysed with concept analysis method. Twenty‐six studies were included and five themes were identified. Four themes formed the basis of assistance towards family caregivers by nurses and included “relationship building with professionals,” “negotiating with professional care,” “being professionally supported,” and “managing role expectations and knowledge sharing”. The fifth theme, “working together” described the mutual care for the care recipient. Although the first four themes were consistent with a pre‐existing conceptual model by Sims‐Gould and Marin‐Matthews (2010), the fifth required an expansion of the model with an additional contribution “collaborative practice”. The findings illustrate that involvement in care is an interactional process, which provides the basis for collaborative practices with the home care nurses for family caregivers. Family members often want to be part of the healthcare team, and nurses need contextual factors that allow providing their full range of skills and knowledge to involve family caregivers accordingly.     

Two German CINCA (NOMID) patients with different clinical severity and response to anti-inflammatory treatment

Chronic infantile neurologic, cutaneous, articular (CINCA) syndrome is characterized by fever, chronic meningitis, uveitis, sensorineural hearing loss, urticarial skin rash, and a deforming arthritis. In the CIAS1 gene of many but not all CINCA patients, disease-associated mutations have been found recently. We here describe two such patients from Germany. One of them, a 3-yr-old boy, has a 1709A-->G, Y570C, mutation, which has previously been described to cause CINCA syndrome. His clinical course is very severe and no satisfying response has been achieved even with high doses of local and systemic steroids. The other patient has a somewhat milder clinical course and considerable improvement could be accomplished with moderate and low doses of steroids. In her CIAS1 gene we have found a 1043C-->T, T348M, mutation, which has only been detected in Muckle-Wells syndrome before. Our results suggest that the severity of symptoms in CINCA patients may be influenced by the underlying mutation in the CIAS1 gene. Furthermore, our observations support the view that CINCA syndrome and Muckle-Wells syndrome are essentially the same disease with different degrees of severity.
