The development of a Cognitive Activation Theory of Stress: From limbic structures to behavioral medicine

This paper attempts to argue for a consistent trend in a research spanning more than fifty years, starting in the exciting neuroscience environment in the Anatomical Institute at the University of Oslo, and presently to be found as an active behavioral medicine unit in Bergen. The most comprehensive theoretical result is a systematic and formalized theory of stress, referred to as the Cognitive Activation Theory of Stress, CATS for short ( Ursin & Eriksen, 2004 ). There are many roots, many related issues, and many scientists involved. There is no way to produce a complete story. However, one aspect is beyond discussion, the story started in the Neurophysiology laboratory in Oslo.     

Manualised health support interventions: Their efficacy in a South African primary healthcare setting

The study examined the implementation efficacy of a stress-reduction intervention for people living with HIV/AIDS by health care workers in the Eastern Cape Province, South Africa. Informants were 20 health care workers drawn from two health facilities. There were 17 females (85%) and 3 males (15%). Participants engaged in a focus group discussion on their experiences using a theory-based manualised stress-reduction support intervention in primary care settings. Thematic content analysis of the data yielded the following themes characterising costs to faithful implementation: departure from manualised instructions and ad hoc improvisation of theoretical concepts; disruptive power dynamics; lack of grounding in community values; and implementation resource limitations. Manualised intervention implementation efficacy by health workers needs customisation to local culture and health service support services.     

Sleep in Women: A Review

Sleep complaints are common in women, and women are more likely to suffer from insomnia than men. Multiple factors across a woman's lifespan, including hormonal changes, age‐related physiological changes, psychosocial factors, the presence of sleep disorders, and physical and mental health conditions, can contribute to complaints of poor sleep in women. This article reviews the literature on the characteristics of, and contributing factors to, subjectively and objectively measured sleep during the menstrual cycle, pregnancy, and post‐partum period, as well as the menopausal transition and postmenopause. Evidence from both subjective and objective measurements supports the presence of chronic sleep fragmentation associated with pregnancy, acute sleep deprivation during labour and the immediate post‐partum periods, as well as disrupted sleep during the first few months after childbirth. While there is evidence for menstrual cycle and menopause related sleep disturbance based on women's self report, findings from objectively measured sleep have been mixed. Observational and intervention studies on the relationship between sleep and women's psychological well‐being suggest that underlying causes of sleep disturbance across a woman's lifespan are often multi‐factorial. Comprehensive assessments and targeted interventions are needed in managing sleep problems in women. Cognitive behavioural interventions have been shown to reduce sleep complaints during the perinatal and menopausal periods, and improvements in sleep are likely to lead to improvements in women's overall well‐being.     

Measuring Daytime Drowsiness in Nursing Home Residents: The MSLT-NH

A standardized method of assessing daytime drowsiness in frail nursing home residents has not been previously available. We present here the development and test characteristics of an instrument to measure daytime drowsiness in nursing home residents with cognitive and functional impairment, the Multiple Sleep Latency Test-Nursing Home (MSLT-NH). In a standardized manner, the resident is tested three times in one day (at 9 a.m., 11 a.m., and 1 p.m.) to measure the amount of time until the subject falls asleep. The average sleep latency (minutes to fall asleep) is the measure of interest. We tested the MSLT-NH in 95 residents from six community nursing homes in the Los Angeles area (82% of subjects were female; 81% were white, mean age was 86.6 years and mean score on the Mini-Mental State Examination [MMSE] was 9.4). Interrater reliability of the MSLT-NH was quite good (correlations between raters ranged from 0.98 to 0.99; all p values were <.0001). Validity was assessed by comparing MSLT-NH results to simultaneous wrist activity estimation of sleep, and by comparing MSLT-NH findings to results from nighttime sleep estimation by wrist actigraphy the night prior to MSLT-NH. The percent agreement between MSLT-NH and wrist actigraph ranged from 77% to 79% MSLT-NH results were significantly associated with peak duration of nighttime sleep episodes the night prior to testing. The MSLT-NH was also quite acceptable for use in the NH setting. In conclusion, we have developed a promising measure of daytime drowsiness in NH residents. Further testing will help establish whether this test is a clinically useful measure of daytime drowsiness from medications or other conditions in the NH setting.     

阻塞性睡眠呼吸暂停低通气综合征与冠状动脉支架再狭窄关系的研究

探讨冠状动脉内支架再狭窄与阻塞性睡眠呼吸暂停低通气综合征（OSAHS）的关系及其机制.选择冠状动脉支架植入术后患者172例,其中43例确诊患OSAHS者为研究组,129例无OSAHS的患者为对照组.支架术后第3年行冠状动脉造影术,同时检测患者静脉血中TNF-α、IL-6、IL-4、IL-5、IL-10水平.OSAHS患者7例发生支架内再狭窄,比率16.26%,明显高于对照组6例,比率5.67%（P〈0.01）;OSAHS患者血清中TNF-α、IL-6浓度高于对照组（P〈0.01）;IL-4、IL-5、IL-10水平低于对照组（P〈0.01）.合并OSAHS的患者,支架再狭窄的发生率高于非OSAHS患者,而OSAHS引发的炎症介质水平改变及炎症反应失衡可能与支架再狭窄有关.     

Repetitive Thought and Self-Reported Sleep Disturbance

Repetitive thought has been focused upon as a transdiagnostic risk factor for depression, anxiety, and poor physical health. Among the forms of repetitive thought, rumination and worry are considered to play important roles in the onset and maintenance of insomnia. However, there have been few attempts to clarify the similarities, differences, and interaction between the functions of rumination and worry in sleep problems. Furthermore, no study has investigated the prospective relationships between these two forms of repetitive thought and sleep disturbance. In the present study, we examined the prospective associations between repetitive thought and subjective sleep quality, measured by a self-report questionnaire. A total of 208 undergraduates participated in a 2-wave longitudinal survey with an interval of 3 weeks between assessments. Hierarchical multiple regression analyses showed that baseline rumination predicted reduction in the follow-up assessment of subjective sleep quality, controlling for levels of depressive and anxious symptoms. This main effect of rumination was qualified by the levels of worry; for individuals with higher levels of worry, rumination was associated with greater reduction in subjective sleep quality. These results suggest that both rumination and worry have unique associations with sleep and that their interaction is especially important in sleep problems.
