Two validation studies were conducted to optimize the sleep-detection algorithm of the Actillume. The first study used home recordings of postmenopausal women (age range: 51 to 77 years), which were analyzed to derive the optimal algorithm for detecting sleep and wakefulness from wrist activity data, both for nocturnal in-bed recordings and considering the(More)
Patterns of sleep, illumination, and activity of women of different ages were continuously monitored in their natural environments with a wrist activity monitor. Partial correlation analyses were performed to determine relationships between age and sleep and several circadian rhythm measures including the amplitudes, mesors, and timings of sleep, of(More)
BACKGROUND The American Cancer Society's Cancer Prevention Study II was a large survey designed primarily to examine cancer risks such as cigarette smoking. From the same survey and methods, data on usage of "prescription sleeping pills" in 1982 were examined. METHODS Standardized mortality ratios were computed. Because sleeping pill use could be a proxy(More)
BACKGROUND A randomized and controlled clinical study was performed to evaluate the use of neurofeedback (NF) to treat attention-deficit/hyperactivity disorder (ADHD) in children and adolescents. METHODS The ADHD population was selected from an outpatient clinic for Child and Adolescent Mental Health in Norway. Ninety-one of the 275 children and(More)
BACKGROUND The aim of this study was to measure chest compression decay during simulated advanced life support (ALS) in a cardiac arrest manikin model. METHODS 19 paramedic teams, each consisting of three paramedics, performed ALS for 12 minutes with the same paramedic providing all chest compressions. The patient was a resuscitation manikin found in(More)
BACKGROUND Music therapy (MT) has been shown to be efficacious for mental health care clients with various disorders such as schizophrenia, depression and substance abuse. Referral to MT in clinical practice is often based on other factors than diagnosis. We aimed to examine the effectiveness of resource-oriented MT for mental health care clients with low(More)
OBJECTIVE This study sought to identify potential differing clinical characteristics between patients with a mild traumatic brain injury (MTBI) who attended a planned follow-up session and not. This study investigated whether clinical characteristics and attendance for a planned follow-up service 2-months after injury could be related to return-to-work(More)
A significant variation in the metastatic pattern among breast cancer patients exists. Clinical observations suggest that these differences are related to time to recurrence (TTR), thus suggesting a common systemic growth signal at the time of surgery. Our goal was to identify a marker for synchronized growth of micrometastases. To quantify the metastatic(More)
