Friendships reduce risky behaviors in homeless youth

2013-07-30
(Press-News.org) Homeless young women may be at greater risk for sexually transmitted infections (STIs) than homeless young men because of the structure of their social groups and friendships, according to new research from UC San Francisco. The findings underscore how the social networks of homeless youth can be highly influential, affecting their participation in risky and protective behaviors.

The study examined the relationship between STI rates and the characteristics of the social networks of 258 homeless young people ages 15 to 24 in San Francisco. The youth were surveyed about their housing status, risky behaviors and social networks. They also were tested for Chlamydia and gonorrhea.

The researchers found that the homeless young women had lower condom use and a higher likelihood of sex with intravenous drug users than the homeless young men. The women also showed a trend toward higher rates of sexually transmitted infections.

“We thought that homeless young women may be at higher risk in part because of whom they had access to in their network,” said lead author Annie Valente, MD, who conducted the research while a medical student at UCSF. “Social networks are proving to be a very important indicator for other health outcomes, including obesity and cigarette smoking.”

Study participants were homeless for two nights or more during the previous six months. Each participant took a computer-based survey, and created a table reflecting their social networks from the previous three months. They listed people to whom they felt close, sex partners, injection partners, and people with whom they had shared resources.

The study, which will be published in the Journal of Adolescent Health and is now online, also found: homeless young men were more likely than their female counterparts to have contacts with stable housing and same-sex friends. when young men had stably housed contacts in their network, they were more likely to use condoms. female participants were more likely to use condoms when they were able to name a friend of the same gender.

“The presence of same-sex friendships and contacts living in stable homes seems to increase condom use,” said senior author Colette Auerswald, MD, a UCSF associate adjunct professor of pediatrics and director of the Masters in Medical Science program for the UC Berkeley-UCSF Joint Medical Program. She was based at the UCSF Division of Adolescent Medicine of the UCSF Benioff Children’s Hospital at the time of the study. “Young homeless men seem to name these social network contacts more frequently than do young homeless women. It will be important in future investigations to ask why this happens.”

The presence of family in the social networks of the young women played an important role in their risk of having sexual partners who are intravenous drug users (IDU). None of the females who listed a family member in their network had an IDU sex partner, whereas 26.4 percent of the women who did not list a family member had an IDU sex partner.

“This study shows the importance of reconnecting homeless young men and women to mainstream society,” said Valente. “It also emphasizes how same-gender friendships and family ties may be effective tools in our efforts to improve the health of homeless youth.”

The data collected were part of the Street Youth in Social Environments study, a longitudinal NIH-funded study conducted by Auerswald examining the relationships among street culture, social networks and STI/HIV risk in homeless youth in San Francisco.

This study builds on research that used the same sample of homeless youth in San Francisco to investigate the impact of social networks on shelter use among homeless youth. Published in the June issue of the Journal of Adolescent Health, the researchers found that street youth whose social networks included people who used shelters, increased the odds of their own shelter use over time.

“Together these studies suggest the value of designing social network-based interventions to improve the health of our city’s marginally housed youth,” said Auerswald.

Stress early in life leads to adulthood anxiety and preference for 'comfort foods'

2013-07-30
7/30/13, New Orleans, LA. Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, suggests that exposure to stress in the first few days of life increases stress responses, anxiety and the consumption of palatable "comfort" foods in adulthood. "Comfort foods" have been defined as the foods eaten in response to emotional stress, and are suggested to contribute to the obesity epidemic. Hormonal responses to chronic stress in adulthood seem ...

Taste preference changes in different life stages of rats

7/30/13, New Orleans, LA. Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, found that aging elicits changes in taste preferences and that such changes appear to be independent of taste nerve activity. In humans and animals aging decreases dietary and energy requirements and it is generally believed that reduced consumption is related to alterations in taste preference. However, the mechanisms underlying an age-induced shift in taste ...

Fetal 'programming' of sweet taste's elicited pleasure

2013-07-30
7/30/13, New Orleans, LA. Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, suggests that feeding behavior and preferences may be shaped very early during development, even during fetal life. Newborns of different species react to the sweet taste demonstrating facial expressions of pleasure, such as licking (tongue protusions) and thumb sucking. These "hedonic" responses are related to brain activity in regions that respond to pleasure ...

A maternal junk food diet alters development of opioid pathway in the offspring

2013-07-30
7/30/13, New Orleans, LA. Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, shows that eating a junk-food diet during pregnancy changes the development of the opioid signalling pathway in the baby's brain and permanently alters the way this system operates after birth. Opioids are chemicals which are released when we eat foods that are high in fat and sugar, and that are responsible for causing the release of another 'feel good' chemical, ...

Severe low blood sugar occurs often in patients with Type 2 diabetes

2013-07-30
OAKLAND, Calif., July 30, 2013 — Patients with diabetes who take certain types of medications to lower their blood sugar sometimes experience severe low blood sugar levels, whether or not their diabetes is poorly or well controlled, according to a new study by Kaiser Permanente and Yale University School of Medicine. The finding, published in the current online issue of Diabetes Care, challenges the conventional wisdom that hypoglycemia is primarily a problem among diabetic patients with well-controlled diabetes (who have low average blood sugar levels). Low blood sugar ...

Sanford-Burnham researchers uncover how a potent compound kills prostate cancer cells

2013-07-30
A JOLLA, Calif., July 30, 2013 — One major hallmark of cancer cells is their ability to survive under stressful conditions. A new study spearheaded by researchers at Sanford-Burnham Medical Research Institute reveals how a promising anticancer compound called SMIP004 specifically kills prostate cancer cells by compromising their ability to withstand environmental stress. The study, recently published in Oncotarget, uncovers novel mechanisms of anticancer activity and could lead to the development of more effective therapies for advanced and hard-to-treat forms of prostate ...

A smart way of using testosterone to prevent muscle wasting

2013-07-30
New Australian research suggests that a small dose of testosterone directed solely to the liver stimulates protein synthesis, likely preventing muscle loss and wasting, and potentially promoting muscle growth. The researchers believe they have developed a safe and effective treatment for men and women, that could prevent the muscle wasting associated with many chronic diseases and with ageing. Dr Vita Birzniece and Professor Ken Ho, from Sydney's Garvan Institute of Medical Research, showed in healthy postmenopausal women that a small dose of the male hormone testosterone ...

How to learn successfully even under stress

2013-07-30
Whenever we have to acquire new knowledge under stress, the brain deploys unconscious rather than conscious learning processes. Neuroscientists at the Ruhr-Universität Bochum have discovered that this switch from conscious to unconscious learning systems is triggered by the intact function of mineralocorticoid receptors. These receptors are activated by hormones released in response to stress by the adrenal cortex. The team of PD Dr Lars Schwabe from the Institute of Cognitive Neuroscience, together with colleagues from the neurology department at the university clinic ...

Picosecond accurate slow-motion confirms oxide materials exhibit considerably faster switching properties than do semi-conductors

2013-07-30
This news release is available in German. Materials that have the ability to switch between being good conductors and being good insula-tors are considered good potential candidates for electronic building blocks – for use in transis-tors, for example. The iron oxide magnetite is the best known representative of this class of ma-terials. At low temperatures, magnetite has insulating properties; at high temperatures, the oxide is a good conductor. This switching mechanism however happens so quickly that it's been im-possible until now to fully grasp it on an atomic ...
