Abstract
The growth of online support groups has led to an expression effects paradigm within the health communication literature. Although religious support expression is characterized as a typical subdimension of emotional support, we argue that in the context of a life-threatening illness, the inclusion of a religious component creates a unique communication process. Using data from an online group for women with breast cancer, we test a theoretical expression effects model. Results demonstrate that for breast cancer patients, religious support expression has distinct effects from general emotional support messages, which highlights the need to further theorize expression effects along these lines.

Abstract
Animal epidemiological and clinical studies suggest that cholesterol is a risk factor for Alzheimer's disease (AD). Nevertheless, the relation of cholesterol to mild cognitive impairment (MCI), influence of APOE genotype and its changes in lifespan is controversial. We investigated the potential impact of plasma total cholesterol (TC) on development of MCI and AD in the interdisciplinary longitudinal study on adult development and aging, a representative birth cohort (born 1930-1932), examined in 1993/1994 (VT1), 1997/1998 (VT2), and 2005/2007 (VT3). Of 500 participants at baseline, 381 survived and were examined at VT3. After exclusion of participants with lifetime prevalence of major psychiatric diseases or mild cognitive disorder due to a medical condition, 222 participants were included in the analysis. At VT3, 82 participants had MCI, 22 participants had AD, and 118 were in good health. Participants with MCI and AD at VT3 evidenced higher TC levels at VT1 than those who were healthy. Higher TC levels at baseline were associated with an increased risk for cognitive disorders at VT3 (highest vs. lowest quartile: OR 2.64, 95 % CI 1.12-6.23, p < 0.05). Over the 14 year follow-up, TC levels declined in those with MCI and AD, but remained stable in those who remained healthy. These findings were not modified by APOE genotype or use of cholesterol-lowering medications. Our findings demonstrate that higher TC levels are observed long before the clinical manifestation of MCI and AD in patients without psychiatric or somatic comorbidities and are independent of APOE genotype.

Abstract
Several systems for treating alcohol-use disorders (AUDs) exist that operate on mobile phones. These systems are categorized into four groups: text-messaging monitoring and reminder systems, text-messaging intervention systems, comprehensive recovery management systems, and game-based systems. Text-messaging monitoring and reminder systems deliver reminders and prompt reporting of alcohol consumption, enabling continuous monitoring of alcohol use. Text-messaging intervention systems additionally deliver text messages designed to promote abstinence and recovery. Comprehensive recovery management systems use the capabilities of smart-phones to provide a variety of tools and services that can be tailored to individuals, including in-the-moment assessments and access to peer discussion groups. Game-based systems engage the user using video games. Although many commercial applications for treatment of AUDs exist, few (if any) have empirical evidence of effectiveness. The available evidence suggests that although texting-based applications may have beneficial effects, they are probably insufficient as interventions for AUDs. Comprehensive recovery management systems have the strongest theoretical base and have yielded the strongest and longest-lasting effects, but challenges remain, including cost, understanding which features account for effects, and keeping up with technological advances.

Abstract
Squeezed states of light are an important tool for optical measurements below the shot noise limit and for optical realizations of quantum information systems. Recently, squeezed vacuum states were deployed to enhance the shot noise limited performance of gravitational wave detectors. In most practical implementations of squeezing enhancement, relative fluctuations between the squeezed quadrature angle and the measured quadrature (sometimes called squeezing angle jitter or phase noise) are one limit to the noise reduction that can be achieved. We present calculations of several effects that lead to quadrature fluctuations, and use these estimates to account for the observed quadrature fluctuations in a LIGO gravitational wave detector. We discuss the implications of this work for quantum enhanced advanced detectors and even more sensitive third generation detectors.

Abstract
OBJECTIVE This paper seeks to contribute to the understanding of how and why religion affects psychosocial health outcomes. We propose a theoretical model predicting that when women with breast cancer defer control to God they will experience fewer breast cancer related concerns. Deferring control to God, however, should also reduce the likelihood that they take a proactive coping approach, which will be exacerbated by lowered breast cancer concerns. We therefore predict that this passive coping style will ultimately result in lower levels of quality of life. METHODS Data were collected as part of a randomized clinical trial funded by the National Cancer Institute. A total of 192 women with breast cancer participated in a computer-mediated social support group. Deferring control to God statements were captured by using computer-aided content analysis of discussion posts. Psychosocial outcomes were measured using longitudinal survey data. Analysis was performed using structural equation modeling. RESULTS The results of our analysis largely confirm our mediation model for which we find significant model fit. As predicted, deferring control to God leads to lower levels of breast cancer concerns but also to more passive coping styles. Ultimately, deferring control to God can lead to lower levels of quality of life. CONCLUSIONS Our study demonstrates how and why religious coping can lead to both positive and negative psychosocial health outcomes. Health care practitioners should encourage patients who are relying on religion to keep their end of the bargain and maintain an active coping style.

Abstract
Implementing specific evidence-based practices (EBPs) across a set of addiction treatment providers have been a persistent challenge. In the Advancing Recovery(AR) demonstration project, single state agencies, the entities that distribute federal funds for substance use disorder prevention and treatment services, worked in partnership with providers to increase the use of EBPs in the treatment of addiction. The project supported two cohorts of six 2-year awards. Field observations from the first year of implementation guided development of a multilevel framework (the Advancing Recovery Framework). Government entities and other payers can use the framework as a guide for implementing evidence-based clinical practices within treatment networks. The Advancing Recover Framework calls for a combination of policy and organizational changes at both the payer (government agency) and provider levels. Using the Advancing Recovery Framework, 11 of the 12 AR payer/provider partnerships increased use of clinical EPBs. This article identifies key payer policy changes applied during different phases of EBP program implementation. The public health benefit of the demonstration project was broader use of medication-assisted therapy and continuing care in addiction treatment services.

Abstract
This article describes how 121 women newly diagnosed with breast cancer used a computer mediated discussion group to cope with their diagnosis. These data are part of a larger data set from a randomized clinical trial assessing the impact of a computer-based system called CHESS (the Comprehensive Health Enhancement Support System) on health outcomes. The larger study found significant improvement in health outcomes for those in the experimental group (those receiving CHESS), especially for women of color. Since discussion group is by far the most heavily used service of CHESS, one might conclude that these benefits (both overall and greater for women of color) should be attributed to amount of discussion group use. This study looks at how women of color and Caucasian women used the CHESS discussion group over the period of the study. Content analysis of messages in the discussion group showed that women of color used the discussion group differently from Caucasian women-they used it less frequently but their messages were more focused on breast cancer, suggesting they used discussion group more instrumentally.

Abstract
This paper reports on the phone scheduling systems that patients encounter when seeking addiction treatment. Researchers made a series of 28 monthly calls to 192 addiction treatment clinics to inquire about the clinics' first available appointment for an assessment. Each month, the date of each clinic's first available appointment and the date the appointment was made were recorded. During a 4-month baseline data collection period, the average waiting time from contact with the clinic to the first available appointment was 7.2 days. Clinics engaged in a 15-month quality improvement intervention in which average waiting time was reduced to 5.8 days. During the course of the study, researchers noted difficulty in contacting clinics and began recording the date of each additional attempt required to secure an appointment. On average, 0.47 callbacks were required to establish contact with clinics and schedule an appointment. Based on these findings, aspects of quality in phone scheduling processes are discussed. Most people with addiction seek help by calling a local addiction treatment clinic, and the reception they get matters. The results highlight variation in access to addiction treatment and suggest opportunities to improve phone scheduling processes.

Abstract
Background Asthma is the most common pediatric illness in the United States, burdening low-income and minority families disproportionately and contributing to high health care costs. Clinic-based asthma education and telephone case management have had mixed results on asthma control, as have eHealth programs and online games. Objectives To test the effects of (1) CHESS+CM, a system for parents and children ages 4–12 years with poorly controlled asthma, on asthma control and medication adherence, and (2) competence, self-efficacy, and social support as mediators. CHESS+CM included a fully automated eHealth component (Comprehensive Health Enhancement Support System [CHESS]) plus monthly nurse case management (CM) via phone. CHESS, based on self-determination theory, was designed to improve competence, social support, and intrinsic motivation of parents and children. Methods We identified eligible parent–child dyads from files of managed care organizations in Madison and Milwaukee, Wisconsin, USA, sent them recruitment letters, and randomly assigned them (unblinded) to a control group of treatment as usual plus asthma information or to CHESS+CM. Asthma control was measured by the Asthma Control Questionnaire (ACQ) and self-reported symptom-free days. Medication adherence was a composite of pharmacy refill data and medication taking. Social support, information competence, and self-efficacy were self-assessed in questionnaires. All data were collected at 0, 3, 6, 9, and 12 months. Asthma diaries kept during a 3-week run-in period before randomization provided baseline data. Results Of 305 parent–child dyads enrolled, 301 were randomly assigned, 153 to the control group and 148 to CHESS+CM. Most parents were female (283/301, 94%), African American (150/301, 49.8%), and had a low income as indicated by child’s Medicaid status (154/301, 51.2%); 146 (48.5%) were single and 96 of 301 (31.9%) had a high school education or less. Completion rates were 127 of 153 control group dyads (83.0%) and 132 of 148 CHESS+CM group dyads (89.2%). CHESS+CM group children had significantly better asthma control on the ACQ (d = –0.31, 95% confidence limits [CL] –0.56, –0.06, P = .011), but not as measured by symptom-free days (d = 0.18, 95% CL –0.88, 1.60, P = 1.00). The composite adherence scores did not differ significantly between groups (d = 1.48%, 95% CL –8.15, 11.11, P = .76). Social support was a significant mediator for CHESS+CM’s effect on asthma control (alpha = .200, P = .01; beta = .210, P = .03). Self-efficacy was not significant (alpha = .080, P = .14; beta = .476, P = .01); neither was information competence (alpha = .079, P = .09; beta = .063, P = .64). Conclusions Integrating telephone case management with eHealth benefited pediatric asthma control, though not medication adherence. Improved methods of measuring medication adherence are needed. Social support appears to be more effective than information in improving pediatric asthma control.

Abstract
PURPOSE The purpose of this retrospective study was to determine the rate of continuing care for dental trauma patients seen after-hours in a hospital emergency department (ED) and identify predictors for and barriers to seeking continuing care. METHODS Records of 856 patients treated at Nationwide Children's Hospital (NCH) ED for dental trauma between September 2003 and December 2007, were screened for avulsion, luxation, and intrusion injuries. A qualifying cohort (QC) of 175 patients was included based on injury and root development. A quality assurance survey was conducted with 96 parents of these patients to determine barriers and predictors for follow-up treatment. RESULTS Patients averaged 2.5 follow-up visits at NCH. The most commonly reported barriers to receiving treatment were: having to miss school (21%), taking time off of work (17%), and costs associated with dental care (13%). No statistical significance (P=.22) was found between number of follow-up visits and the patient retaining the injured tooth. The number of follow-up visits was not significantly different between patients with private and public insurance. CONCLUSIONS School, work, and costs associated with ongoing trauma management affect follow-up compliance irrespective of payment source.

Abstract
IAGG, WHO, and SFGG organized a international workshop on Health promotion programs on prevention of late on-set dementia. Thirty world specialists coming from Europe, North America, Asia, South America, Africa and Australia, shared their experience on methods and results of large epidemiological interventions to reduce incidents of dementia or delay its on-set. Chaired by Laura FRATIGLIONI, an expert in Epidemiological studies on dementia issues, the workshop gave opportunity for discussions and controversies about the state-of-the-art. Based on different national and international trials (ADAPT, MAPT, FINGER, GUDIAGE, GEM etc) the questions remained opened for different aspects of methodology, the choice of domain or multi domain intervention, the choice and the definition of the target populations, the best age of candidates, the issues related to the discrepancy between late effects, and interventions' duration. We are please to publish in the Journal, the presentations presented to this workshop. These publications will complete previously task force published in the journal in the last two years on methodological issues for Alzheimer's trials including end point, biomarkers, and the experience of past therapeutic trials.

Abstract
BACKGROUND Individuals aged 80 years and older is the fastest growing segment of the population worldwide. To understand the biology behind increasing longevity, it is important to examine factors related to survival in this age group. The relationship between brain atrophy and survival after age 85 remains unclear. METHODS A population-based sample (n = 239) had head CT scans at age 85 and was then followed until death. Cortical atrophy and ventricular size were assessed. Statistical analyses included Cox proportional hazards models with time to death as the outcome and considering a large number of possible confounders, including baseline cognitive function, incident dementia, and somatic disorders. RESULTS Mean survival time (±SD) was 5.0 ± 3.6 years (range 0.10-19.8 years). Decreased survival was associated with temporal, and frontal atrophy, sylvian fissure width and a number of ventricular measures after adjustment for potential confounders. In participants without dementia at baseline (n = 135), decreased survival was associated with temporal lobe atrophy and bifrontal ratio. In those with dementia (n = 104), decreased survival was associated with third ventricle width, cella media ratio, and ventricle-to-brain and ventricle-to-cranial ratio. CONCLUSIONS Several indices of brain atrophy were related to decreased survival after age 85, regardless of dementia status. Brain atrophy is rarely mentioned as a significant indicator of survival in the elderly, independent of traditional predictors such as cardiovascular disease or cancer. The biology behind the influence of brain atrophy on survival needs to be further scrutinized.

Abstract
UNLABELLED Quantitative imaging biomarkers could speed the development of new treatments for unmet medical needs and improve routine clinical care. However, it is not clear how the various regulatory and nonregulatory (eg, reimbursement) processes (often referred to as pathways) relate, nor is it clear which data need to be collected to support these different pathways most efficiently, given the time- and cost-intensive nature of doing so. The purpose of this article is to describe current thinking regarding these pathways emerging from diverse stakeholders interested and active in the definition, validation, and qualification of quantitative imaging biomarkers and to propose processes to facilitate the development and use of quantitative imaging biomarkers. A flexible framework is described that may be adapted for each imaging application, providing mechanisms that can be used to develop, assess, and evaluate relevant biomarkers. From this framework, processes can be mapped that would be applicable to both imaging product development and to quantitative imaging biomarker development aimed at increasing the effectiveness and availability of quantitative imaging.

To understand the underlying psychosocial reactions against the unfolding of medical events that announce the disease progression, the objective of this analysis was to identify the patterns of online discussion group message themes in relation to the medical timeline of one woman's breast cancer trajectory. 202 messages posted by Darlene (our studied case) were analyzed by 2 independent coders using a grounded theory approach. The findings suggest that the pattern of messages was clearly correlated with distress-inducing events. The most frequent interaction theme was about building friendship with peers through communication of encouragement, validation, appreciation, and life sharing. Narratives of medical progression were constantly updated to identify similarities with peers. Family issues were increasingly raised at the end of life.

Abstract
BACKGROUND Successive elderly birth cohorts improved in cognitive performance during the 20th century. It is not clear whether this influences cognitive predictors of dementia and mortality. OBJECTIVE In 2 longitudinal population studies, representing 2 cohorts of 70-year-olds examined 30 years apart, we investigated the relation between baseline cognitive function and 5-year occurrence of dementia and mortality. METHODS Two representative cohorts of 70-year-olds initially free from dementia born in 1901-1902 (cohort 1901-1902: n = 381) and 1930 (cohort 1930: n = 551) from Gothenburg, Sweden, were examined in 1971-1972 and 2000-2001 and after 5 years for the outcome of dementia and death. Recent memory was evaluated during psychiatric examinations, and nonmemory domains using psychometric tests. RESULTS At age 70, cohort 1930 performed better on psychometric tests, and had fewer recent memory problems compared to cohort 1901-1902. During 5-year follow-up, 5.0% in cohort 1901-1902 and 4.4% in cohort 1930 (p = 0.742) developed dementia, and 15.7% in cohort 1901-1902 and 4.4% in cohort 1930 died (p < 0.001). Recent memory was associated with incident dementia in both cohorts. Low scores in nonmemory tests were associated with incident dementia in cohort 1901-1902, but not in cohort 1930. Recent memory problems and lower scores in nonmemory tests were associated with 5-year mortality in cohort 1901-1902, but not in cohort 1930. CONCLUSIONS Secular changes in cognitive performance may influence cognitive predictors of dementia and mortality, despite similar incidence of dementia. The findings should be taken cautiously due to differences between cohorts in refusal rates, quality of education, and dementia recognition in medical records.

Abstract
The goal of the current study was to examine how social support and coping strategies are related in predicting emotional well-being of women with breast cancer. In achieving this goal, we examined two hypothesized models: (1) a moderation model where social support and coping strategies interact with each other in affecting psychological well-being; and (2) a mediation model where the level of social support influences choices of coping strategies between self-blame and positive reframing. In general, the data from the current study were more consistent with the mediation model than the moderation model.
