(Press-News.org) Philadelphia, August 15, 2013 – Research suggests that a patient's chronic pain affects a spouse's emotional well-being and marital satisfaction. In a novel study of behavioral health outcomes published in the journal PAIN®, researchers examined the effects of patients' daily knee osteoarthritis pain on their spouses' nightly sleep. They determined that couples who expressed a high degree of closeness in their marriage experienced a stronger association between pain levels and the spouse's ability to sleep restfully. Findings further illustrated that chronic pain may place the spouse's health at risk and suggest an important therapeutic target for couples.
"Sleep is a critical health behavior, and individuals whose sleep is affected by their partner's pain are at risk for physical and psychiatric problems," says lead investigator Lynn M. Martire, PhD, Department of Human Development & Family Studies, Penn State University, University Park, Pennsylvania. "Spouses whose sleep is compromised may also be less able to respond empathically to patients' symptoms and need for support."
The research team chose to study knee pain because of the difficulty many patients experience in getting comfortable in bed and staying asleep. In addition, the resulting restlessness may disturb the patient's partner. Investigators sought to test two hypotheses:
Greater osteoarthritis pain during the day would be associated with poorer sleep for the spouse that night
A couple's degree of closeness affects the relationship between pain and sleep
The team collected data from 145 couples who recorded their levels of pain, sleep quality, and level of feeling rested or refreshed over 22 consecutive nights of sleep. Eligible participants were husbands or wives who had been diagnosed with knee osteoarthritis by a physician, who experienced usual knee pain of moderate or great intensity, were at least 50 years old, and were married or in a long-term relationship in which they shared a residence with their partners.
Data analysis indicated:
Patients' reports of sleep quality did not significantly correlate with their pain on the previous day, but they did relate to beginning-of-day reports of pain.
When patients reported greater knee pain at the end of the day, their spouses slept poorly that night and reported feeling less refreshed the following morning.
Spouses who reported symptoms of depression and negative moods upon awakening were more likely to experience poor sleep quality and less refreshing sleep.
In close relationships, the greater a patient's pain, the less refreshing the sleep for the spouse.
"Compromised sleep caused by exposure to a loved one's suffering may be one pathway to spousal caregivers' increased risk for health problems, including cardiovascular disease," concludes Dr. Martire. "In developing behavioral couple-oriented interventions for arthritis, it is important to identify the couples in which the spouse is most affected by patient suffering. Our findings suggest that assessing the extent to which partners are closely involved in each other's lives would help to identify spouses who are especially at risk for being affected by patient symptoms and in need of strategies for maintaining their own health and well-being."

The first animal model for sexual transmission of HIV
Infection by human immunodeficiency virus (HIV) causes acquired immunodeficiency syndrome (AIDS), a debilitating disorder in which progressive weakening of the immune system makes affected individuals more susceptible to potentially life-threatening infections and chronic diseases. Despite advances in the treatment and management of AIDS, there is no cure, and HIV infection remains a major global health problem. According to the WHO, there were an estimated 34 million infected individuals in 2011. Over the last three decades, a number of animal models have been developed ...
Chronicling cancer experience online can reduce depressive symptoms in breast cancer patients
Adults increasingly are conveying their personal experiences with serious disease online, but do such chronicles help the authors or their audience? In the first known study of its kind, UCLA researchers discovered that creating a personal website to chronicle the cancer experience and communicate with one's social network can reduce depressive symptoms, increase positive mood and enhance appreciation for life among women diagnosed with breast cancer. The study, published online Aug. 12 in the Journal of Clinical Oncology (and scheduled for print publication at ...
Plastic solar cells' new design promises bright future
Energy consumption is growing rapidly in the 21st century, with rising energy costs and sustainability issues greatly impacting the quality of human life. Harvesting energy directly from sunlight to generate electricity using photovoltaic technologies is considered to be one of the most promising opportunities to produce electricity in an environmentally benign fashion. Among the various photovoltaic technologies, polymer (plastic) solar cells offer unique attractions and opportunities. These solar cells contain Earth-abundant and environmentally benign materials, can ...
1-pot to prep biomass for biofuels
The advantages of the "one-stop" shop have long been recognized in the retailing and services industries. Similar advantages would also be realized for the biofuels industry with the development of a "one-pot" processing system in which sugars could be extracted from biomass and turned into fuels in a single vat. A major step forward in this goal has now been achieved by researchers with the U.S. Department of Energy (DOE)'s Joint BioEnergy Institute (JBEI) who report the first demonstration of a one-pot, wash-free, process for the ionic liquid pretreatment and saccharification ...
Digital streak camera captures full-color photographs of high-speed objects
LAGUNA HILLS, California, USA -- Researchers at MetroLaser, Inc., have developed a new design for a digital streak camera that captures full-color images of projectiles traveling up to 3350 m/s, which is 10 times the speed of sound. This system was designed to replace the outdated film-based streak cameras that are still in use at high-speed test tracks. Film-based streak photography records the motion of an object as it passes in front of a camera lens, while the film moves behind a vertical slit aperture during the exposure. The result is a long, continuous composite ...
Children of obese mothers face risk of early death, study shows
Children born to obese mothers are more likely to die early as adults than those whose mothers were a normal weight, a study has found. The offspring of obese mothers are one-third more likely to die before the age of 55, mainly as a result of heart disease, researchers found. Children born to mothers who were overweight when they became pregnant were also 10 per cent more likely to die prematurely in later life than those born to mothers of a normal weight. The study, carried out by the Universities of Edinburgh and Aberdeen, examined the health records of more ...
Children of obese mothers at greater risk of early heart death as adults
Children of obese and overweight women have a higher risk of early cardiovascular death as adults, finds a study published on bmj.com today. The findings highlight the urgent need for strategies to prevent obesity in women of childbearing age and the need to assess the offspring of obese mothers for their cardiovascular risk, say the authors. Rates of maternal obesity have risen rapidly in the past two decades. In the United States, about 64% of women of reproductive age are overweight and 35% are obese, with a similar pattern in Europe. Many studies have shown a ...
How bacteria found in mouth may cause colorectal cancer
Gut microbes have recently been linked to colorectal cancer, but it has not been clear whether and how they might cause tumors to form in the first place. Two studies published by Cell Press on August 14th in the journal Cell Host & Microbe reveal how gut microbes known as fusobacteria, which are found in the mouth, stimulate bad immune responses and turn on cancer growth genes to generate colorectal tumors. The findings could lead to more effective strategies for the early diagnosis, prevention, and treatment of colorectal cancer. "Fusobacteria may provide not only ...

Stanford scientists get a handle on what made Typhoid Mary's infectious microbes tick
STANFORD, Calif. — Stanford University School of Medicine scientists have shown how salmonella — a bacterial menace responsible for hundreds of thousands of deaths each year from typhoid fever and food poisoning — manages to hide out in immune cells, altering their metabolism to its own benefit, much as someone might remodel a newly rented home to suit his own comfort. Salmonella's ability to position itself inside infected people's cells for the long haul can turn them into chronic, asymptomatic carriers who, unknown to themselves or others, spread the infectious organism ...
