I Get by with a Little Help from my Family and Friends: Adolescents' Support for Diabetes Care

Evaluated and compared the support provided by family membersand friends for adolescents' diabetes care. Family and friendsupport also were examined in relation to other measures ofsocial support, to demographic variables (age, gender, durationof diabetes) and to adherence. Using a structured interview,74 adolescents with diabetes described the ways that familymembers and friends provided support for diabetes management(insulin shots, blood glucose monitoring, eating proper meals,exercise), and for helping them to "feel good about their diabetes."Families provided more support than friends for three managementtasks (insulin injections, blood glucose monitoring, meals);this support was largely instrumental. In contrast, friendsprovided more emotional support for diabetes than families.Greater family support was related to younger age, shorter diseaseduration, and better treatment adherence. Implications of thefindings include encouraging parents to remain involved in adolescents'treatment management, and involving peers as supportive companionsfor meals and exercise.

Relationship quality moderates the effect of social support given by close friends on cardiovascular reactivity in women

We examined the role of the type of support provided, gender of support provider, and relationship quality in predicting how social support might influence cardiovascular reactivity during acute stress in women. A group of 88 women received either emotional, instrumental, or no support from a close female or male friend while performing a series of speech tasks. Results suggest that the effectiveness of social support for women depended primarily on the quality of the friendship (i.e., purely positive, or ambivalent). More specifically, women who interacted with a female, ambivalent friend had the largest changes in diastolic blood pressure, total peripheral resistance (TPR), and pre-ejection period compared to the other conditions. Furthermore, receiving emotional support from a purely positive friend was related to lower increases in cardiac output (CO) compared to a no-support condition. In contrast, receiving emotional support from an ambivalent friend was related to larger increases in CO and only small changes in TPR when compared to individuals in the no-support condition. These data are discussed in light of the psychosocial processes underlying social support effects in women, and the importance of a more comprehensive view of how close relationships influence cardiovascular function.

The rheumatic patient''s early needs and expectations

During the last few years, studies have revealed that the need for psychosocial support and concrete social services are great in the early stages of the treatment of rheumatic diseases. The ability to keep a job, to do household chores, to participate in leisure activities and to maintain social relations is clearly impaired. Anxiety and depression are not unusual and often associated with weak support from relatives, loneliness and disturbed family relations. Nevertheless, the patients report resilience and determination to cope with the impacts of illness. Crisis intervention, vocational guidance and counselling about problems concerning the disease should be available and offered to the patients. As the patients seem to be unaccustomed to talking about their psychosocial problems, an empathetic and information-seeking attitude on the part of the health care staff is essential.     

Eye tracking as an objective measure of hyperphagia in children with Prader‐Willi syndrome

This study examined sensitivity of eye tracking measures to hyperphagia severity in Prader‐Willi syndrome (PWS). Gaze data were collected in 57 children with PWS, age 3–11 years, and 47 typically developing peers at two study sites during free visual exploration of complex stimulus arrays that included images of food, animals, and household objects. Analysis of the number and duration of fixations as well as gaze perseverations revealed that food items are not exceptionally salient for children with PWS. Instead, increased attention to food in the context of other high‐interest items (e.g., animals) was associated with caregiver reports of more severe hyperphagia and more advanced nutritional phase. The study also provided preliminary evidence of possible genetic subtype and sex differences as well as demonstrated that multiple investigators in a wide range of settings can effectively implement the eye tracking protocol. The results indicate that gaze characteristics derived from eye tracking may be a promising objective marker of hyperphagia in PWS for use in research and clinical trials.     

吸毒者的社会支持及与心身健康水平的相关分析

Psychosocial factors regulating natural-killer cell activity in recurrent spontaneous abortions

PROBLEM: The preconceptional natural-killer cell (NK) activity predicts subsequent miscarriage among women with unexplained recurrent spontaneous abortion (RSA). Psycho-neuro-immuno-endocrine network has recently been proposed as a mechanism for abortions. We therefore examined which psychosocial factors influenced the NK activity among women with RSA. METHOD OF STUDY: We measured the preconceptional NK activity of 61 women with a history two consecutive unexplained first-trimester miscarriages and no live births. We also administered semi-structured interviews and a battery of self-report questionnaires to assess their social support, personality, self-esteem and psychiatric symptoms. RESULTS: The preconceptional NK activity was negatively correlated with the women's neuroticism personality trait (r= -0.32, P = 0.01) and current depressive symptoms (r = -0.26, P= 0.05), and positively correlated with their self-esteem (r = 0.34, P = 0.01). CONCLUSIONS: In addition to several substances such as transforming-growth-factor beta and granulocyte-macrophase colony-stimulating factor, we found that low neuroticism, low depression scale score and high self-esteem contributed to high NK activity among women with RSA.
