Embodied cognitive restructuring: The impact of posture and movement on changing dysfunctional attitudes.

BACKGROUND AND OBJECTIVES: Previous theoretical and empirical work has pointed to the important role of the body in emotion generation and emotion regulation. In the present study, we wanted to investigate if the performance of certain body postures and movement could facilitate cognitive restructuring of dysfunctional cognitive attitudes more effectively than traditional, verbal-only methods. METHODS: In total, 130 participants were randomized to one of two groups. One group was subjected to cognitive restructuring (i.e., restructure only group; CR-only), verbally exploring a dysfunctional attitude from a curious, strong, and courageous perspective. The other group received the same verbal instructions but in addition to this, was asked to perform different bodily exercises (i.e., motor-enhanced restructuring group; M-CR) supposed to enhance experience of the different perspectives from which cognitive restructuring was employed. RESULTS: Results confirmed the primary hypothesis, showing that the M-CR-group showed a larger decline in belief in dysfunctional attitudes compared with the CR-only group (F = 4.2, p = 0.041, d = 0.25). No differences on secondary outcomes were observed between the two groups. LIMITATIONS: Future research should explore the effects of motor-enhanced CR both more long-term (e.g., durability over weeks) and in clinical samples (e.g., anxiety and depression). CONCLUSION: Should the findings be replicated in clinical samples, it is encouraging that simple bodily exercises can enhance the effect of one of the most central skills of cognitive therapy.

Effects of psychological interventions on systemic levels of inflammatory biomarkers in humans: A systematic review and meta-analysis.

The purpose of the present investigation was to systematically review randomized controlled trials examining the effects of psychological interventions on inflammatory biomarkers in adult populations and to quantitatively analyze those effects by meta-analysis. Two researchers independently searched key electronic databases, selected eligible publications, extracted data, and evaluated methodological quality. Nineteen randomized controlled trials examining a total of 1510 participants were included. The overall combined effect size from pre to post psychological intervention on pro-inflammatory biomarker levels was statistically significant, showing an attenuating effect, although of a small magnitude (s' g = 0.15, p = .008, CI [0.04-0.26]). However, this effect was not maintained into the follow-up period (g < -0.01, p = .964, CI [-0.19-0.18]). Looking at the individual biomarkers assessed across studies, only C-reactive protein (CRP) was found to significantly decrease following psychological intervention. A number of moderation analyses were conducted, none of which reached statistical significance. However, the numerically largest - and significant - within-group effect size was obtained for the group of studies that had preselected participants based on elevated psychological distress (g = 0.29, p = .047). In conclusion, psychological interventions appear efficacious in reducing pro-inflammatory biomarker levels. Future studies are recommended to carefully select individuals based on inflammatory (e.g., the presence of low-grade inflammation) and/or psychological (e.g., psychological distress) criteria.

Clinical and psychological moderators of the effect of mindfulness-based cognitive therapy on persistent pain in women treated for primary breast cancer - explorative analyses from a randomized controlled trial.

BACKGROUND: Mindfulness-based intervention has been found efficacious in reducing persistent pain in women treated for breast cancer. Little, however, is known about possible moderators of the effect. We explored clinical and psychological moderators of the effect on pain intensity previously found in a randomized controlled trial of mindfulness-based cognitive therapy (MBCT) with women treated for breast cancer with persistent pain. MATERIAL AND METHODS: A total of 129 women treated for breast cancer reporting persistent pain were randomized to MBCT or a wait-list control. The primary outcome of pain intensity (11-point numeric rating scale) was measured at baseline, post-intervention, three, and six months follow-up. Proposed clinical moderators included age, axillary lymph node dissection (ALND), radiotherapy, and endocrine treatment. Psychological moderators included psychological distress [the Hospital Anxiety and Depression Scale (HADS)], the adult attachment dimensions anxiety and avoidance [the Experiences in Close Relationships Short Form (the ECR-SF)], and alexithymia [the Toronto Alexithymia Scale (TAS-20)]. Multi-level models were used to test moderation effects over time, i.e. time × group × moderator. RESULTS: Only attachment avoidance (p = 0.03, d = 0.36) emerged as a statistically significant moderator. Higher levels of attachment avoidance predicted a larger effect of MBCT in reducing pain intensity compared with lower levels attachment avoidance. None of the remaining psychological or clinical moderators reached statistical significance. However, based on the effect size, radiotherapy (p = 0.075, d = 0.49) was indicated as a possible clinical moderator of the effect, with radiotherapy being associated with a smaller effect of MBCT on pain intensity over time compared with no radiotherapy. CONCLUSION: Attachment avoidance, and potentially radiotherapy, may be clinically relevant factors for identifying the patients who may benefit most from MBCT as a pain intervention. Due to the exploratory nature of the analyses, the results should be considered preliminary.

Web-based cognitive training for breast cancer survivors with cognitive complaints-a randomized controlled trial.

BACKGROUND: Cognitive complaints are common amongst breast cancer survivors, and no standard treatment exists. The present study evaluates whether web-based cognitive training can alleviate subjectively reported and objectively assessed cognitive complaints in a sample of breast cancer survivors. The primary and secondary outcomes were an objective measure of working memory and a measure of perceived cognitive functioning. Additional outcomes were neuropsychological tests of memory, executive function, working memory and questionnaire-based assessment of anxiety, depression and somatization. METHODS: A total of 157 female breast cancer survivors were recruited from an existing cohort and through announcements in open access cancer-related Internet fora and randomly allocated to either web-based cognitive training (eCogT) with telephone support (n = 94) or a waitlist control (WLC) condition (n = 63). eCogT encompassed 30 training sessions over 6 weeks. Neuropsychological assessments were undertaken over the telephone, and questionnaire data was collected online. Data was collected at baseline, post-intervention and at 5-month follow-up. RESULTS: Mixed linear models revealed no statistically significant change in primary or secondary outcome at follow-up in either group. Statistically significant improvements (p 0.040-0.043) were found in the eCogT group for verbal learning and on a working memory test. CONCLUSIONS: Web-based cognitive training did not result in improvements of the primary or secondary outcome. Improved performance was observed on verbal learning and working memory. These effects were observed at 5-month follow-up, indicating long-term effects of training. The intervention may be applied in a clinical setting at low cost and without risk of adverse effects.© 2016 The Authors Psycho-Oncology Published by John Wiley & Sons Ltd.

Social anxiety and emotion knowledge: a meta-analysis.

It has been proposed that social anxiety is associated with poor emotion knowledge (EK), although studies have revealed mixed results. The aim of the present paper was to systematically investigate the association between EK and both non-clinical and clinical social anxiety by means of meta-analyses. Systematic, electronic database literature searches were performed, and meta-analyses were conducted on 43 included studies. Results showed that social anxiety was negatively associated with EK. The strongest association was found between clinical levels of social anxiety and the ability to understand one's own emotions (intrapersonal EK). Regarding interpersonal EK, a subgroup analysis showed that social anxiety was more strongly associated with a decreased ability to understand complex emotions than to recognize basic emotions. No differences were found between patients with social anxiety disorder (SAD) and patients with other anxiety disorders. Although a large between study heterogeneity and differing methodologies may prevent any firm conclusions from being reached, the results indicate that poor EK may play an important role in SAD, and that it could be beneficial to target EK in the treatment of SAD.

Building care systems to improve access for high-risk and vulnerable veteran populations.

BACKGROUND: For many high-risk patients, accessing primary care is challenged by competing needs and priorities, socioeconomics, and other circumstances. The resulting lack of treatment engagement makes these vulnerable patient populations susceptible to poor health outcomes and an over-reliance on emergency department-based care. METHODS: We describe a quasi-experimental pre-post study examining a vulnerable population-based application of the patient-centered medical home applied to four high-risk groups: homeless veterans, cognitively impaired elderly, women veterans and patients with serious mental illness. We measured 6-month primary care, emergency department and inpatient care use and chronic disease management when care was based in a general internal medicine clinic (2006) and in a population-specific medical home (2008). RESULTS: Overall 457 patients were studied, assessing care use and outcomes for the last 6 months in each study year. Compared with 2006, in 2008 there was a significant increase in primary care use (p < 0.001) and improvement in chronic disease monitoring and diabetes control (2006 HBA1C: 8.5 vs. 2008 HBA1C 6.9) in all four groups. However, there was also an increase in both emergency department use and hospitalizations, albeit with shorter lengths of stay in 2008 compared with 2006. Most of the increased utilization was driven by a small proportion of patients in each group. CONCLUSION: Tailoring the medical home model to the specific needs and challenges facing high-risk populations can increase primary care utilization and improve chronic disease monitoring and diabetes management. More work is needed in directing this care model to reducing emergency department and inpatient use.

Smoking prolongs the infectivity of patients with tuberculosis.

We sought to establish if smokers on anti-tuberculosis treatment are more likely to have a prolonged period of infectivity, compared to non-smoking tuberculosis patients, in a low tuberculosis prevalence country. We conducted a cross-sectional, retrospective study in Ireland that recruited 53 microbiologically confirmed cases of pulmonary tuberculosis (PTB). The age-sex adjusted odds ratios (AOR) suggest that the infectivity status of PTB on treatment was four times more likely to be prolonged beyond 6-8 weeks, if the cases had a smoking history (AOR: 4.42; 95% CI: 1.23; 15.9). Smoking was associated with delayed sputum smear conversion in PTB patients on treatment.

In vitro allergen challenge of peripheral blood induces differential gene expression in mononuclear cells of asthmatic patients: inhibition of cytosolic phospholipase A2alpha overcomes the asthma-associated response.

BACKGROUND: Existing treatments for asthma are not effective in all patients and disease exacerbations are common, highlighting the need for increased understanding of disease mechanisms and novel treatment strategies. The leukotriene pathway including the enzyme responsible for arachidonic acid release from cellular phospholipids, cPLA(2)alpha, is a major contributor to asthmatic responses and an attractive target in asthma therapies. OBJECTIVE: The study reported here investigates (a) the differential effects of in vitro exposure of peripheral blood mononuclear cells (PBMCs) to allergen between asthma and healthy subjects, and (b) the contribution of cPLA(2)alpha to these differences in gene expression. METHODS: In vitro responses of asthma (N=26) and healthy (N=11) subject PBMC samples to allergen stimulation in the presence and absence of cPLA(2)alpha inhibition or 5-lipoxygenase inhibition were compared at the gene expression level using oligonucleotide arrays and at the protein level using ELISA. RESULTS: Subject samples within both asthma and healthy groups showed allergen-dependent cytokine production and allergen-dependent gene expression changes, although transcriptional profiling identified 153 genes that were modulated significantly differently by allergen between asthma and healthy subjects. Among these were genes previously associated with asthma, but the majority (about 80%) have not previously been associated with asthma. CONCLUSIONS: Transcriptional profiling elucidated novel gene expression differences between the asthmatic and healthy subject samples. Although 5-lipoxygenase inhibition did not significantly affect allergen-modulated gene expression, the inhibition of cPLA(2)alpha activity affected many of the allergen-dependent, asthma-associated gene expression changes.

A novel and sensitive ELISA reveals that the soluble form of IL-13R-alpha2 is not expressed in plasma of healthy or asthmatic subjects.

BACKGROUND: IL-13 plays a key regulatory role in asthmatic responses and immunity to parasitic infection. In vivo, IL-13R-alpha2 is a critical modulator of IL-13 bioactivity. When inducibly expressed on the surface of fibroblasts and other cell types under inflammatory conditions, IL-13R-alpha2 contributes to resolution of IL-13 responses. A soluble form of IL-13R-alpha2 (sIL-13R-alpha2) can be detected in murine circulation, and functions as a regulator of IL-13 bioactivity. In humans, sIL-13R-alpha2 has been more difficult to detect. Recently, novel assay systems have been described to quantitate sIL-13R-alpha2 in human circulation, and revealed unexpectedly high levels of sIL-13R-alpha2 in healthy subjects. OBJECTIVE: To verify sIL-13R-alpha2 quantitation in human plasma samples under stringent conditions of signal verification and false-positive detection. METHODS: A standard ELISA protocol was evaluated for specificity using false-positive detection reagents. A more stringent ELISA protocol was developed by optimizing the composition of blocking and dilution buffers. RESULTS: Using the stringent assay protocol, endogenous sIL-13R-alpha2 was undetectable in plasma samples from a total of 120 asthmatics and 20 healthy subjects, and in bronchoalveolar lavage fluid from 10 asthmatics and eight healthy subjects undergoing allergen challenge. CONCLUSION: These results underscore the necessity to perform rigorous assay controls in the biological matrix to be tested. Because the soluble form could not be demonstrated, our findings question a role for sIL-13R-alpha2 in the regulation of IL-13 bioactivity, and highlight the potentially important contribution of the membrane-bound form of IL-13R-alpha2 in humans.

Incidence-angle dependence of optical reflectivity difference from an ultrathin film on solid surface.

We studied the incidence-angle dependence of the optical reflectivity difference in response to ultrathin films on transparent and opaque substrates. We found that the classical three-layer model reproduces the experimentally obtained angular dependence for a monolayer of xenon on Nb(110) and for a monolayer of protein molecules on functionalized glass. We explore the enhancement of the optical response near the Brewster angle (or its equivalent for opaque substrates) in thin film detection.

Treating first episode psychosis--the service users' perspective: a focus group evaluation.

UK national guidance has prioritized developing specialist services for first episode psychosis. Such services are in the early stages of development and a definitive treatment model has yet to be established. The aim of this study was to explore service users' experiences of a first episode intervention designed along evidence-based 'best practice' guidelines and to establish specific elements seen as effective to help inform future service planning and provision. Twelve users of a specialist first episode service participated in focus groups. These were then analyzed using Interpretative Phenomenological Analysis, a specialized form of content analysis. Key elements identified by the service users included the 'human' approach as a key to the recovery process, being involved in treatment decisions, flexibility of appointments, high nurse to patient ratio, reduction in psychotic symptoms, increased confidence and independence and the provision of daily structure. To our knowledge, this is the first systematic qualitative evaluation of users' experience of a specialist first episode treatment intervention. Our findings indicate that adherence to best practice guidelines was appreciated. Regular focus groups provide a continuous audit cycle incorporating service improvements in line with government recommendations, centrally informed by the service users' and caregivers' perspective.

Sending children home on tracheostomy dependent ventilation: pitfalls and outcomes.

In spite of the consistency of the primary discharge coordinator in our practice and attempts to streamline the process, the obstacles to discharge highlighted five years ago remain frustratingly similar. The children in this survey spent an average of 9.6 months extra time in hospital awaiting discharge at considerable cost to the local commissioning teams, quite apart from the emotional cost to the child and stress for the whole family. We hope in future years this review will enable health practitioners and local health providers to anticipate the hurdles, address the problems early, and expedite the process of discharging home children who are dependent on long term ventilation via tracheostomy.

Health Opportunities with Physical Exercise (HOPE): social contextual interventions to reduce sedentary behavior in urban settings.

Physical activity interventions targeting social and physical environments of the urban poor hold promise in improving health outcomes in underserved communities. This study randomly assigned overweight, sedentary, economically disadvantaged adults to one of three intervention conditions at The Hope and Healing Center, a large inner-city health facility providing numerous options for exercise. Within the tenets of Social Action Theory, the Health Opportunities with Physical Exercise (HOPE) trial will test the efficacy of two behavior change models, social support and patient-provider interaction, to increase physical activity. In addition to a standard care condition, in which patients have open access to Hope and Healing physical activity programming, patients were assigned to one of two behavior change interventions. Those assigned to patient-peer receive face-to-face, systematic and scheduled encouragement from study-trained 'peer' interventionists at the facility. Patients assigned to patient-provider receive face-to-face, systematic and scheduled encouragement provided by study-trained 'provider' interventionists also at the facility. The primary outcomes of change in exercise behavior will be documented by self-reported physical activity and confirmed by fitness testing at baseline, 6, 12 and 24 months during the 1 year of active intervention and 1 year of relapse prevention follow-up. Intervention conditions will be compared on psychosocial mediators including motivational appraisals, ratings of social support, rapport, problem solving and self-efficacy for overcoming barriers to increased physical activity. Novel aspects of this intervention include: (1) delivery of socially based physical activity interventions to an economically disadvantaged urban population, (2) reduction of environmental barriers to be physically active and (3) emphasis on social interactions influencing health habit change. Results of this study have the potential to identify mechanisms of behavior change that could be adopted by physical activity interventions aimed at reducing sedentary behavior and health disparities in high-risk, underserved populations.

Effectiveness of the electronic medical record in cholesterol management in patients with coronary artery disease (Virtual Lipid Clinic).

This study demonstrates that the Virtual Lipid Clinic, an electronic medical record with computer-assisted cholesterol management, is associated with improved lipid management in patients with coronary artery disease. In comparison to traditional documentation methods with "pen and paper" charts, outpatient visits utilizing the electronic medical record were associated with a twofold increase in low-density lipoprotein (LDL) documentation, a threefold increase in achieving LDL goal, and a 30% increase in the use of lipid-lowering drugs.

Gender differences in exercise-induced changes in sex hormone levels and lipid peroxidation in athletes participating in the Hawaii Ironman triathlon. Ginsburg-gender and exercise-induced lipid peroxidation.

BACKGROUND: Exercise reduces the risk of coronary heart disease in men and women but paradoxically, may promote free-radical formation, lipid peroxidation and vascular tissue injury. In this study, we assessed whether exercise-induced oxidative stress similarly affected men and women who participated in the Hawaii Ironman triathlon. METHODS AND RESULTS: Fifty-seven athletes (38 males) who completed the triathlon (3.9 km swim, 180.2 km bike, 42.2 km run) participated in this study. Blood samples were obtained 2 days before and immediately after the triathlon for the measurement of lipids, antioxidants and sex hormones and for the assessment of the susceptibility of plasma lipids to peroxidation. Lipid changes after exercise were similar for men and women. However, the susceptibility of plasma lipids to peroxidation was reduced by 61% (P < 0.001) in men and only 14% (P = NS) in women postrace. These changes were not associated with the supplemental use or levels of antioxidants. In addition, in men there was an increase of 58% in the antioxidant sex hormone estradiol and a decrease of 58% in testosterone (P < 0.001) postrace. No significant changes were noted for these two hormones in women. CONCLUSIONS: There are significant gender-specific differences in the susceptibility of lipids to peroxidation and in changes in estradiol and testosterone levels as a result of ultra-endurance exercise. These changes may in part explain the salutary effect of exercise on the development of vascular disease.

High-density lipoprotein cholesterol and vascular stiffness at baseline in the activity counseling trial.

In a middle-aged patient population, age was associated with stiffer vessels and high-density lipoprotein cholesterol with more elastic vessels. High-density lipoprotein cholesterol may be an indirect indicator of aerobic capacity or of less atherosclerosis, suggesting mechanisms for preserving vascular integrity.

Discharge planning for complex paediatric cases.

The aim of this study was to identify the functions performed by social workers specifically engaged in paediatric discharge planning by undertaking a detailed analysis of discharge planning practice in forty cases referred to a specialist discharge planning team, at the Royal Children's Hospital, Melborne. A second aim was to identify the characteristics that distinguished complex cases from more routine cases. Discharge planning activity focused on the family, community and the organisation, with most cases requiring activity in all three areas. More complex cases were characterised by amount of social work time spent on the case, length of stay and number of discharge planner functions performed, but not number of prior admissions.

Do sweat calcium losses affect bone mass during firefighter training?

Although participation in vigorous exercise is associated with increased bone mass, recent evidence suggests that loss of calcium in sweat may result in a negative calcium balance and, ultimately, a decrease in bone mass. Anthropometric characteristics, habitual physical activity levels, dietary calcium intake, bone mineral content, and bone turnover markers were measured in 42 male recruits before and after 4 months of firefighter training. During two strenuous mid-training sessions, sweat calcium concentrations were measured; they averaged 1.1 mM. Whole body and total hip bone mineral content increased significantly, as did one marker of bone formation, and were not associated with sweat calcium concentration. This study demonstrates that intense physical training sessions that produce high sweat rates do not have an adverse effect on the bone mineral content of healthy young men.
