The notion that chronic stress fosters disease by activating the hypothalamic-pituitary-adrenocortical (HPA) axis is featured prominently in many theories. The research linking chronic stress and HPA function is contradictory, however, with some studies reporting increased activation, and others reporting the opposite. This meta-analysis showed that much of the variability is attributable to stressor and person features. Timing is an especially critical element, as hormonal activity is elevated at stressor onset but reduces as time passes. Stressors that threaten physical integrity, involve trauma, and are uncontrollable elicit a high, flat diurnal profile of cortisol secretion. Finally, HPA activity is shaped by a person's response to the situation; it increases with subjective distress but is lower in persons with posttraumatic stress disorder.

www.mobilehealthmap.org 617‐442‐3200 New research shows that mobile health clinics improve health outcomes for hard to reach populations in cost‐effective and culturally competent ways . A Harvard Medical School study determined that for every dollar invested in a mobile health clinic, the US healthcare system saves $30 on average. Mobile health clinics, which offer a range of services from preventive screenings to asthma treatment, leverage their mobility to treat people in the convenience of their own communities. For example, a mobile health clinic in Baltimore, MD, has documented savings of $3,500 per child seen due to reduced asthma‐related hospitalizations. The estimated 2,000 mobile health clinics across the country are providing similarly cost‐effective access to healthcare for a wide range of populations. Many successful mobile health clinics cite their ability to foster trusting relationships. Qualitative research in such mobile health clinics has found that patients value the informal, familiar environment in a convenient location, with staff who “are easy to talk to,” and that the staff’s “marriage of professional and personal discourses” provides patients the space to disclose information themselves. A communications academic argued that mobile health clinics’ unique use of space is important in facilitating these relationships. Mobile health clinics park in the heart of the community in familiar spaces, like shopping centers or bus stations, which lend themselves to the local community atmosphere.

Hypocortisolism and increased glucocorticoid sensitivity of pro-inflammatory cytokine production in Bosnian war refugees with posttraumatic stress disorder.

The objectiveofthis study was to analyze associations of three indicators of perceived work stress (physical job demand, low control at work, andan imbalance between effort and reward), and of overcommitment, a personal pattern of coping with work demands, with musculoskeletal pain. A standardized questionnaire measuring these conditions in addition to self-reported musculoskeletal pain at different locations was administered to a group of 316 male and female employees of a public transport enterprise. After we adjusted for confounding effects of age, sex, socioeconomic status, shift work, and negative affectivity, we observed elevated prevalence odds ratios in employees who scored high on overcommitment, who were exposed to physical job demand, and, to a lesser extent, who reported psychosocial work stress. Results have implications for a more comprehensive approach to primary and secondary prevention of musculoskeletal pain.

Perceived work stress, overcommitment, and self-reported musculoskeletal pain: Across-sectional investigation

The aim of this study is to evaluate the effects of a trauma-focused psychotherapy upon war refugees from Bosnia. Seventy refugees who met the criteria for posttraumatic stress disorder (PTSD) and somatoform disorders were included. The first 35 refugees were offered psychotherapy and the following 35 refugees received usual care. Outcome variables were changes in self-reported PTSD symptoms, psychological symptoms, and health status. At 12-month follow-up, participants in the intervention group reported significantly lower scores on the PTSD scale and the measure of psychological symptoms than the comparison group participants. Our results suggest that psychotherapy reduces symptoms of PTSD and somatoform disorders among war refugees even in the presence of insecure residence status.

Effects of trauma-focused psychotherapy upon war refugees.

During acute psychological stress, the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system are activated. The released stress hormones influence glucose metabolism, can activate immune cells, and modulate subclinical inflammation. The aim of our study was to analyze the effect of acute psychological stress on glucose metabolism and the inflammatory status in patients with post-traumatic stress disorder (PTSD). We included 15 overweight male Bosnian war refugees with PTSD into the study (mean age 44+/-11 years, BMI 29.3+/-4.3 kg/m (2)). All subjects underwent an oral glucose tolerance test (OGTT) with either acute stress (trauma script exposure) or a resting period in a cross-over design. Blood was drawn over 2.5 h and metabolic markers were measured. Systemic levels of immune markers were determined using high-sensitive ELISA or bead-based multiplex assay. Immune gene expression was quantified by RT-PCR. After being exposed to acute stress, cortisol levels and heart frequency tended to be increased. Higher blood glucose and insulin levels after stress exposure were observed (p<0.05). Systemic levels of the chemokines interferon-gamma-inducible protein-10 and macrophage chemoattractant protein-1 were decreased compared to the control day (both p<0.05) and the expression of the proinflammatory regulator IKK beta was significantly reduced after stress exposure (p<0.001). In conclusion, acute stress induces postprandial blood glucose peaks and elevated insulin levels and a selective decrease of systemic immune markers and the proinflammatory regulator of the NF kappaB cascade, which are associated with type 2 diabetes. This points towards an independent effect of acute psychological stress on glucose metabolism and inflammation.
