Cognitive-behavioral stress management intervention effects on anxiety, 24-hr urinary norepinephrine output, and T-cytotoxic/suppressor cells over time among symptomatic HIV-infected gay men

Salivary CRP predicts treatment response to virtual reality exposure therapy for social anxiety disorder

BACKGROUND

Social anxiety disorder (SAD) places a profound burden on public health and individual wellbeing. Systemic inflammation may be important to the onset and maintenance of SAD, and anti-inflammatory treatments have shown promise in relieving symptoms of SAD. In the present study, we conducted secondary analyses on data from a randomized clinical trial to determine whether C-reactive protein (CRP) concentrations and social anxiety symptoms decreased over the course of virtual reality exposure therapy, and whether changes in social anxiety symptoms as a function of treatment varied as a function of CRP.

METHOD

Adult participants (N = 78) with a diagnosis of SAD (59 % female) were randomized to receive exposure therapy alone, or exposure therapy supplemented with scopolamine. Social anxiety symptoms, salivary CRP, and subjective units of distress were measured across three exposure therapy sessions, at a post-treatment extinction retest, and at a 1-month follow-up.

RESULTS

CRP decreased over the course of treatment, b = -0.03 (SE = 0.01), p =.02 95 %CI [-0.06, -0.004], as did all social anxiety symptom domains and subjective distress. Higher CRP was associated with greater decreases from pre-treatment to 1-month follow-up in fear, b = -0.45 (SE = 0.15), p =.004 95 %CI [-0.74, -0.15], and avoidance, b = -0.62 (SE = 0.19), p =.002 95 %CI [-1.01, -0.23], and in-session subjective distress from pre-treatment to post-treatment, b = -0.42 (SE = 0.21), p =.05 95 %CI [-0.83, -0.001]. However, declines in CRP were not correlated with declines in fear, r = -0.07, p =.61, or avoidance, r = -0.10, p =.49, within-persons.

CONCLUSIONS

Virtual reality exposure therapy may be associated with an improvement in systemic inflammation in patients with severe SAD. Pre-treatment CRP may also be of value in predicting which patients stand to benefit the most from this treatment.

Efficacy of psychosocial interventions to reduce affective symptoms in sexual and gender minorities: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ) individuals are more likely than cisgender heterosexuals to experience mental, physical, and sexual health issues. A promising contemporary strategy to address the issue of affective symptoms in sexual and gender minorities (SGM) is psychosocial intervention.

OBJECTIVE

To systematically evaluate the effect of psychosocial interventions on the improvement of affective symptoms in SGM, and to provide a reference for the implementation of effective psychological interventions for SGM with affective symptoms.

METHODS

Between the date of database construction until December 10, 2022, a computerized search of the English-language literature published both nationally and worldwide was done. 8 literature databases and 3 additional gray databases were searched. We gathered randomized controlled trials that used psychological interventions for SGM. To evaluate risk bias in included papers in accordance with Cochrane cooperation criteria, we used Review Manager 5.4 software. In conjunction with post-test and follow-up data, mean differences were standardized using Stata 12.0 software. Subgroup analysis was used to investigate the cause of heterogeneity. The study was conducted strictly in accordance with PRISMA guidelines, and it was registered on the PROSPERO platform (CRD42023408610).

RESULTS

This review covered 18 research, and 14 studies were included in the meta-analysis. A total of 1194 study cases, including 706 cases from the control group and 488 cases from the experimental group, were included in these investigations. Compared to the control group, the psychosocial intervention group had significantly lower levels of depression (standardized mean difference (SMD) = -0.17;95% CI = [-0.30, -0.04]; p = 0.012) and anxiety (SMD = -0.22; 95% CI = [-0.41, -0.04]; p = 0.01), but no significant differences were found for distress (SMD = -0.19; 95% CI = [-0.45,0.07]; p = 0.021).

CONCLUSION

According to this study, psychosocial interventions helped lessen the symptoms of depression and anxiety in SGM but had no significant effect on their psychological distress. To assess the impact of psychological intervention on SGM, more randomized controlled trials with larger sample sizes and numerous follow-up times should be done.

A 4-session written emotional disclosure intervention lowers 6-month sympathoadrenal urinary output in persons living with HIV

OBJECTIVE

We previously reported that a brief guided written emotional disclosure (WED) intervention resulted in significant reductions in post-traumatic stress disorder (PTSD) symptomology in women, but not men, living with HIV. Levels of 24-hour urinary output of epinephrine (E) and norepinephrine (NE) are shown to be elevated in persons diagnosed with PTSD. The current study tested whether there was an effect for the 4-week WED intervention on 6-month change in urinary E and NE output amongst persons living with HIV.

METHOD

Fourteen women and 11 men living with HIV randomized to four 30-min expressive writing sessions of either trauma writing or daily events writing in the parent trial were included based upon collection of urine specimens at baseline, 1-, and 6-months after the intervention. Total volume (µg) and concentration (µg/ml) of urinary E and NE were derived from the specimens as study outcomes.

RESULTS

Four repeated measures analyses of covariance (ANCOVA) were performed to evaluate study outcomes using trauma- versus daily-writing as the between-subject factors and collection time point as the within-subject factor, controlling for age and sex. A group x time interaction was observed wherein the trauma writing treatment group showed a significantly greater decrease in total urinary output, F(2, 46) = 4.03, p = .03, and concentration, F(2, 46) = 4.74, p = .01 of epinepherine. Post-hoc analyses revealed the interaction effect for the total, F(2, 22) = 4.82, p = .03, and concentration, F(2, 22) = 7.57, p = .005, of urinary E output over 6-months was significant for women. Interactions were not observed in urinary NE output.

CONCLUSIONS

Significant reductions in the total output and concentration of urinary E were found up to 6-months following initiation of a 4-session guided written emotional disclosure intervention. Profiles of sympathoadrenal activity and response to expressive writing differ between men and women living with HIV. Futher research is need to characterize the putative pathways linking sympathoadrenal response to upstream neurobiological function and downstream inflammatory-immune status in women living with HIV and PTSD.

Cognitive behavioral stress management for parents: Prevention and reduction of parental burnout

Context

Parental burnout increases the risk of deleterious consequences on parents', couples', and children's physical and mental health.

Methods

The current study (N = 134) aimed to assess the effectiveness of a Cognitive Behavioural Stress Management (CBSM) group programme in terms of parental burnout reduction. In total 67 parents attended the 8-week CBSM intervention groups, and another 67 parents were assigned to the waiting-list control group. We compared the effectiveness of the CBSM intervention with a waiting-list control group directly after the end of the programme and at three-months follow-up.

Results

The results showed that compared to the control group the CBSM programme contributed to the reduction of parental burnout symptoms with statistically significant and small effect size. Moreover, the contrast analyses showed that the reduction in parental burnout severity was maintained at 3 month-follow-up. The reduction in parental burnout scores was mediated by the decrease in stress and the increase in unconditional self-kindness.

Conclusions

These results highlight the potential benefits of the CBSM programme for parental burnout prevention and reduction.

Comparative efficacy of psychological interventions on immune biomarkers: A systematic review and network meta-analysis (NMA)

Psychological interventions are viable, cost-effective strategies for improving clinical and psychological impact of inflammation-related conditions. However, their efficacy on immune system function remains controversial. We performed a systematic review and frequentist random-effects network meta-analysis of randomised controlled trials (RCTs) assessing the effects of psychological interventions, against a control condition, on biomarkers of innate and adaptive immunity in adults. PubMed, Scopus, PsycInfo, and Web of Science were searched from inception up to Oct 17, 2022. Cohen's d at 95% confidence interval (CI) was calculated to assess the effect sizes of each class of intervention against active control conditions at post-treatment. The study was registered in PROSPERO (CRD42022325508). Of the 5024 articles retrieved, we included 104 RCTs reporting on 7820 participants. Analyses were based on 13 types of clinical interventions. Compared with the control conditions, cognitive therapy (d =  - 0.95, 95% CI: -1.64 to - 0.27), lifestyle (d =  - 0.51, 95% CI: -0.99 to - 0.02), and mindfulness-based (d =  - 0.38, 95% CI: -0.66 to - 0.09) interventions were associated with post-treatment reduction of proinflammatory cytokines and markers. Mindfulness-based interventions were also significantly associated with post-treatment increase in anti-inflammatory cytokines (d = 0.69, 95% CI: 0.09 to 1.30), while cognitive therapy was associated also with post-treatment increase in white blood cell count (d = 1.89, 95% CI: 0.05 to 3.74). Results on natural killer cells activity were non-significant. Grade of evidence was moderate for mindfulness and low-to-moderate for cognitive therapy and lifestyle interventions; however, substantial overall heterogeneity was detected in most of the analyses.

Effects of a randomized-controlled trial of cognitive behavioral stress management: Psychosocial adaptation and immune status in men with early-stage prostate cancer

OBJECTIVE

Targets of intervention in cognitive behavioral stress management (CBSM), such as benefit finding (BF) and perceived stress management skills (PSMS), may counteract stress-related changes that impact the immune system. This study tested whether BF, PSMS, and optimism influence the effects of CBSM on immune status in men with prostate cancer.

METHODS

Men with prostate cancer were randomized to receive CBSM or a psychoeducation (PE) control comparison (NCT05486754). Life Orientation Test-Revised assessed baseline optimism. The Benefit Finding Scale and Measure of Current Status measured BF and PSMS after CBSM. T-cells and T-helper cells captured immune status change at baseline and 6-months post-CBSM. MPlus and SPSS (PROCESS) tested condition effects and moderated mediation, controlling for covariates.

RESULTS

256 primarily middle-aged, White Non-Hispanic or Hispanic men enrolled. PSMS mediated CBSM effects on T-cell and T-helper cell percentage, such that T-cell and T-helper cell percentages were reduced in men in CBSM versus PE via PSMS. Optimism moderated this mediation with the mediating effect of PSMS only observed among men with average optimism versus those with low or high optimism.

CONCLUSION

Baseline psychological characteristics, as well as limited specificity of immune measurement, could explain the conditional effects in this sample.

Through the Looking-Glass: Psychoneuroimmunology and the Microbiome-Gut-Brain Axis in the Modern Antiretroviral Therapy Era

OBJECTIVE

Depression, substance use disorders, and other neuropsychiatric comorbidities are common in people with HIV (PWH), but the underlying mechanisms are not sufficiently understood. HIV-induced damage to the gastrointestinal tract potentiates residual immune dysregulation in PWH receiving effective antiretroviral therapy. However, few studies among PWH have examined the relevance of microbiome-gut-brain axis: bidirectional crosstalk between the gastrointestinal tract, immune system, and central nervous system.

METHODS

A narrative review was conducted to integrate findings from 159 articles relevant to psychoneuroimmunology (PNI) and microbiome-gut-brain axis research in PWH.

RESULTS

Early PNI studies demonstrated that neuroendocrine signaling via the hypothalamic-pituitary-adrenal axis and autonomic nervous system could partially account for the associations of psychological factors with clinical HIV progression. This review highlights the need for PNI studies examining the mechanistic relevance of the gut microbiota for residual immune dysregulation, tryptophan catabolism, and oxytocin release as key biological determinants of neuropsychiatric comorbidities in PWH (i.e., body-to-mind pathways). It also underscores the continued relevance of neuroendocrine signaling via the hypothalamic-pituitary-adrenal axis, autonomic nervous system, and oxytocin release in modifying microbiome-gut-brain axis functioning (i.e., mind-to-body pathways).

CONCLUSIONS

Advancing our understanding of PNI and microbiome-gut-brain axis pathways relevant to depression, substance use disorders, and other neuropsychiatric comorbidities in PWH can guide the development of novel biobehavioral interventions to optimize health outcomes. Recommendations are provided for biobehavioral and neurobehavioral research investigating bidirectional PNI and microbiome-gut-brain axis pathways among PWH in the modern antiretroviral therapy era.

AWARENESS: A cognitive behavioral intervention to reduce intersectional minority stress among sexual minority men living with HIV who use substances

Introduction:

The minority stress model is the primary explanatory model for disparities in substance use and other mental health problems among sexual minority men (SMM) compared to heterosexual men. This pilot randomized controlled trial tested the feasibility of AWARENESS, a novel 9-session cognitive-behavioral psychotherapeutic intervention that targets intersectional minority stress and stigma, among sexual minority men living with HIV who use substances.

Methods:

Feasibility was determined by the number of participants screened to obtain the target sample size, the percentage of eligible participants randomized, percentage of study intervention and assessment visits attended, time to complete study procedures, and percentage of data completeness of intervention assessments. Forty-two sexual minority men living with HIV with any illicit substance use or who reported at least one occasion of consuming five or more drinks in one setting in the last three months were randomized to AWARENESS (n = 22) or an attention control condition (n = 20).

Results:

Feasibility of the trial was supported, with adequate completion of study procedures and visits (73% completed all intervention sessions, 71% completed all study assessment sessions). This trial also demonstrated the feasibility of using AWARENESS skills and strategies in relation to multiple intersecting identities, with participants discussing an average of 5.7 identities (e.g., sexual orientation) or individual characteristics (e.g., socioeconomic status) in relation to intervention content.

Conclusion:

Our results support the feasibility of an AWARENESS trial to reduce intersectional minority stress related to multiple identities and characteristics among sexual minority men living with HIV who use substances

Study design and protocol for tailored Acceptance and Commitment Therapy (ACT) to optimize quality of life in women living with metastatic breast cancer

Women living with metastatic (stage IV) breast cancer face unique challenges, including arduous treatments, side effects, chronic symptom burden, and emotional distress. Nevertheless, most research has paradoxically focused on optimizing quality of life in women with early-stage, non-metastatic breast cancer. Acceptance and Commitment Therapy (ACT) is an evidence-based, third-wave cognitive behavioral therapy that focuses on creating 'a life worth living' by promoting meaning and purpose and optimizing quality of life. ACT may be particularly well-suited for women with metastatic breast cancer as it addresses salient existential concerns, while allowing for the co-occurrence of feelings of grief and loss that are normal and expected when facing a life-limiting prognosis. This manuscript describes the rationale and study design of a pilot randomized controlled trial to develop and assess the feasibility and acceptability of a tailored ACT intervention for women living with metastatic breast cancer. Participants (N = 30) will be randomized 1:1 to either ACT, cognitive behavioral stress management (CBSM), or a usual care control. Both ACT and CBSM are 8-week, group-based interventions that will be delivered online. Primary outcomes are rates of acceptance, retention, and satisfaction. Preliminary effects on variables of interest, including meaning and purpose, psychological flexibility, and several domains of quality of life, will also be examined. Findings will inform the conduct of a full-scale randomized controlled trial of our tailored ACT intervention in women living with metastatic breast cancer.

The effect of cognitive behavioral stress management on perceived stress, biological stress markers and weight loss/regain, from a diet-induced weight loss program: A randomized controlled trial

Obesity and psychosocial stress are inter-related chronic conditions which lead to increased cardiovascular morbidity and mortality. The aim of this parallel randomized controlled trial was to determine whether the addition of a structured cognitive behavioral stress management (CBSM) on to a commercial online weight loss program, resulted in greater weight loss than the standard weight loss program in isolation. Eligible participants were adults between the ages 18–65, BMI 30–45 kg/m², with no major systemic or psychiatric conditions. Seventy-four participants were assigned according to simple randomization using computer generated random numbers to either a 3-month online Weight Watchers® program (n = 36), or Weight Watchers® plus 10 weekly sessions of CBSM (n = 38). The primary outcome was weight at 3 months compared to baseline. Secondary outcomes were weight at 12 months and subjective/objective stress system measures and metabolic markers at 3 and 12 months. The study was powered at 90% to detect a 5 kg difference in weight between the two groups at 3 months. Independent sample t-tests were used to analyze the difference in weight (in kg) between the groups and paired sample t-tests were used to analyze the difference within group at different time intervals. At follow-up, there was no significant difference in weight loss between the groups (1.8 kg, 2.1 kg). However, CBSM was effective in reducing psychological measures of stress (p < 0.05) and salivary cortisol (waking, 20-min post-waking) at 3-months; with the effect on stress persisting at 12-months within the CBSM group. The reduction in PSS at 3 months was significantly greater in the CBSM group (3.84, p = 0.028) compared to WW only group at 3 months. Addition of CBSM to a standard weight loss intervention did not improve the weight loss over the standard approach on its own, but the CBSM intervention improved psychological stress parameters and cortisol secretion in participants living with obesity.

•

Cognitive behavioral stress management (CBSM) reduced morning cortisol levels.

•

Addition of CBSM to a weight loss program did not augment weight loss.

•

CBSM reduced stress scores.

•

CBSM improved psychometric parameters –SF–12, AAQ-II and PSS.

•

Weight loss may have an effect on reducing stress.

Pilot RCT of a telehealth intervention to reduce symptoms of depression and anxiety in adults with cystic fibrosis

BACKGROUND

Adults with cystic fibrosis (awCF) have higher levels of depression and anxiety than community samples. The Coping and Learning to Manage Stress with CF (CALM) intervention was developed for awCF reporting elevated symptoms of depression or anxiety.

METHODS

In this pilot study, awCF were randomly assigned to either six telehealth sessions (CALM; n = 15) or treatment-as-usual (TAU; n = 16). Primary outcomes were depression and anxiety. Secondary outcomes were coping self-efficacy and health-related quality of life (HrQOL). Tertiary outcomes were feasibility, acceptability, and satisfaction. Assessments were completed at baseline, post-intervention, and 3-month follow-up. Group differences were examined via independent samples t-tests. Effect size (ES) was calculated via Cohen's d to provide a measure of the magnitude of the treatment effect.

RESULTS

At post-intervention, the CALM group had a lower mean score than the TAU group for depression (medium ES) and anxiety (large ES). The CALM group had higher (i.e., better) mean scores than the TAU group for coping (large ES) and HrQOL domains of Social Functioning (large ES) and Vitality (large ES). Most treatment gains were not sustained at 3-month follow-up. CALM was feasible, requiring <12 min. for setup and scheduling, and allowed seamless participation when hospitalized. Mean scores for acceptability and satisfaction indicated that most participants either agreed or strongly agreed that CALM was acceptable and satisfactory.

CONCLUSIONS

CALM shows promise as an intervention to reduce symptoms of depression and anxiety and improve coping and HrQOL. Next steps are to add a booster session and examine CALM via a multi-site RCT.

Association of Gut Microbiome Dysbiosis with Neurodegeneration: Can Gut Microbe-Modifying Diet Prevent or Alleviate the Symptoms of Neurodegenerative Diseases?

The central nervous system was classically perceived as anatomically and functionally independent from the other visceral organs. But in recent decades, compelling evidence has led the scientific community to place a greater emphasis on the role of gut microbes on the brain. Pathological observations and early gastrointestinal symptoms highlighted that gut dysbiosis likely precedes the onset of cognitive deficits in Alzheimer's disease (AD) and Parkinson's disease (PD) patients. The delicate balance in the number and functions of pathogenic microbes and alternative probiotic populations is critical in the modulation of systemic inflammation and neuronal health. However, there is limited success in restoring healthy microbial biodiversity in AD and PD patients with general probiotics interventions and fecal microbial therapies. Fortunately, the gut microflora is susceptible to long-term extrinsic influences such as lifestyle and dietary choices, providing opportunities for treatment through comparatively individual-specific control of human behavior. In this review, we examine the impact of restrictive diets on the gut microbiome populations associated with AD and PD. The overall evidence presented supports that gut dysbiosis is a plausible prelude to disease onset, and early dietary interventions are likely beneficial for the prevention and treatment of progressive neurodegenerative diseases.

Psychosocial Interventions and Immune System Function: A Systematic Review and Meta-analysis of Randomized Clinical Trials

IMPORTANCE

Recent estimates suggest that more than 50% of all deaths worldwide are currently attributable to inflammation-related diseases. Psychosocial interventions may represent a potentially useful strategy for addressing this global public health problem, but which types of interventions reliably improve immune system function, under what conditions, and for whom are unknown.

OBJECTIVE

To address this issue, we conducted a systematic review and meta-analysis of randomized clinical trials (RCTs) in which we estimated associations between 8 different psychosocial interventions and 7 markers of immune system function, and examined 9 potential moderating factors.

DATA SOURCES

PubMed, Scopus, PsycInfo, and ClinicalTrials.gov databases were systematically searched from February 1, 2017, to December 31, 2018, for all relevant RCTs published through December 31, 2018.

STUDY SELECTION

Eligible RCTs included a psychosocial intervention, immune outcome, and preintervention and postintervention immunologic assessments. Studies were independently examined by 2 investigators. Of 4621 studies identified, 62 were eligible and 56 included.

DATA EXTRACTION AND SYNTHESIS

Data were extracted and analyzed from January 1, 2019, to July 29, 2019. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline was followed. Data were extracted by 2 investigators who were blind to study hypotheses and analyses, and were then analyzed using robust variance estimation. Analysis included 8 psychosocial interventions (behavior therapy, cognitive therapy, cognitive behavior therapy [CBT], CBT plus additive treatment or mode of delivery that augmented the CBT, bereavement or supportive therapy, multiple or combined interventions, other psychotherapy, and psychoeducation), 7 immune outcomes (proinflammatory cytokine or marker levels, anti-inflammatory cytokine levels, antibody levels, immune cell counts, natural killer cell activity, viral load, and other immune outcomes), and 9 moderating factors (intervention type, intervention format, intervention length, immune marker type, basal vs stimulated markers, immune marker measurement timing, disease state or reason for treatment, age, and sex).

MAIN OUTCOMES AND MEASURES

The primary a priori outcomes were pretest-posttest-control (ppc) group effect sizes (ppc g) for the 7 immunologic outcomes investigated.

RESULTS

Across 56 RCTs and 4060 participants, psychosocial interventions were associated with enhanced immune system function (ppc g = 0.30, 95% CI, 0.21-0.40; t50.9 = 6.22; P < .001). Overall, being randomly assigned to a psychosocial intervention condition vs a control condition was associated with a 14.7% (95% CI, 5.7%-23.8%) improvement in beneficial immune system function and an 18.0% (95% CI, 7.2%-28.8%) decrease in harmful immune system function over time. These associations persisted for at least 6 months following treatment and were robust across age, sex, and intervention duration. These associations were most reliable for CBT (ppc g = 0.33, 95% CI, 0.19-0.47; t27.2 = 4.82; P < .001) and multiple or combined interventions (ppc g = 0.52, 95% CI, 0.17-0.88; t5.7 = 3.63; P = .01), and for studies that assessed proinflammatory cytokines or markers (ppc g = 0.33, 95% CI, 0.19-0.48; t25.6 = 4.70; P < .001).

CONCLUSIONS AND RELEVANCE

These findings suggest that psychosocial interventions are reliably associated with enhanced immune system function and may therefore represent a viable strategy for improving immune-related health.

AWARENESS: Development of a cognitive-behavioral intervention to address intersectional minority stress for sexual minority men living with HIV who use substances

Sexual minority (i.e., nonheterosexual) individuals are at greater risk than heterosexual individuals for substance use and poor mental health attributed to exposure to minority stress (Meyer, 2003). Minority stress is stress that places an additional burden on sexual minority people over and above the stress experienced by heterosexual people. Sexual minority men may also be subject to minority stress related to intersecting identities or individual characteristics (e.g., HIV status, race). This study obtained initial feedback about the AWARENESS intervention from sexual minority men living with HIV who use substances and determined the feasibility of the intervention to address minority stress related to intersecting identities. AWARENESS is a 9-session cognitive-behavioral intervention targeting minority stress as a driver of greater substance use and poorer mental and physical health. Ten sexual minority men living with HIV who were episodic substance users (>1 episode of illicit drug use or binge drinking in the previous 3 months) began the intervention. Feedback on the intervention was obtained through open-ended interviews analyzed using thematic analysis and Likert scale questionnaires about experiences with the intervention. Therapists tracked identities discussed in relation to minority stress to evaluate feasibility of AWARENESS to address intersectional minority stress. Participants identified they gained cognitive-behavioral skills to cope with intersectional minority stress and described destigmatization and integration of identities. Participants discussed an average of 3.2 identity characteristics in addition to sexual minority status in relation to intervention content. This study lays the groundwork for additional testing of this intervention. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

A Perspective on the Similarities and Differences Between Mindfulness and Relaxation

Mind-body medicine is an evidence-based approach to health and healing that focuses on interactions between the mind, body, and behavior. It encompasses a wide range of interventions that are similar yet different in meaningful ways. Mindfulness and relaxation practices are 2 mind-body techniques that have similarities and differences; however, these techniques are often used or discussed interchangeably, such that the differences between them become obscured. A greater understanding of the unique facets of mindfulness and relaxation is needed for researchers and clinicians to make informed decisions when selecting an approach. The purpose of the current article is to offer an evidence-informed perspective on similarities and differences between mindfulness and relaxation. Specifically, mindfulness and relaxation practices are compared and contrasted in terms of theoretical foundation, intention, and psychological and physiological effects and mechanisms. Implications for clinical practice and suggestions for future research are discussed.

Associations Among Trajectories of Sleep Disturbance, Depressive Symptomology and 24-Hour Urinary Cortisol in HIV+ Women Following a Stress Management Intervention

Objective: The burden of sleep disturbance and depressive symptomology is high for persons living with HIV and particularly so for women. While cognitive behavioral stress management (CBSM) is shown to reduce symptoms of depression and 24-hr urinary free cortisol output (CORT) in HIV+ men, less is known about the effects of CBSM on mood and concomitant sleep disturbance in HIV+ women. The study aim is to model longitudinal change in sleep disturbance, depressive symptomology, and CORT for HIV+ women exposed to a 12-week CBSM intervention or control condition. Methods: Self-reported sleep quality and depressive symptomology, along with CORT, was collected from surveys at baseline and approximately every three months thereafter for nine months from 130 HIV+ women (M_age = 38.44, SD = 7.73). The data was used to specify a parallel process latent growth model with CORT as a time-varying covariate. Results: The model showed acceptable fit. There was a linear decline in sleep disturbance (β = -0.32, p < .05) and logarithmic decline in depressive symptomology (β = -0.33, p < .05) for those receiving the intervention. Decline in sleep disturbance predicted lower CORT at nine months. Furthermore, having less depressive symptoms at baseline was associated with lower initial levels of sleep disturbance and greater improvement in sleep quality over time. There was no discernible association between sleep and mood disturbance in the control group. Across groups, there was a consistent association between older age and greater sleep disturbance (r = 0.34, p < .01). Conclusion: Sleep disturbance appears to be a behavioral target for CBSM in HIV+ women although older age, preintervention levels of depressive mood, and time-varying levels of CORT output may limit improvement in sleep quality over time.

Mind-body practices for people living with HIV: a systematic scoping review

BACKGROUND

Mind-body practices are frequently used by people living with HIV to reduce symptoms and improve wellbeing. These include Tai Chi, Qigong, yoga, meditation, and all types of relaxation. Although there is substantial research on the efficacy of mind-body practices in people living with HIV, there is no summary of the available evidence on these practices. The aim of this scoping review is to map available evidence of mind-body practices in people living with HIV.

METHODS

The Arksey and O'Malley (Int J Soc Res Methodol 8:19-32, 2005) methodological framework was used. A search of 16 peer-review and grey literature databases, websites, and relevant journals (1983-2015) was conducted. To identify relevant studies, two reviewers independently applied the inclusion criteria to all abstracts or full articles. Inclusion criteria were: participants were people living with HIV; the intervention was any mind-body practice; and the study design was any research study evaluating one or several of these practices. Data extraction and risk of bias assessment were performed by one reviewer and checked by a second, as needed, using the criteria that Cochrane Collaboration recommends for systematic reviews of interventions (Higgins and Green, Cochrane handbook for systematic reviews of intervention. 2011). A tabular and narrative synthesis was carried out for each mind-body practice.

RESULTS

One hundred thirty-six documents drawing on 84 studies met the inclusion criteria. The most widely studied mind-body practice was a combination of least three relaxation techniques (n = 20), followed in declining order by meditation (n = 17), progressive muscle relaxation (n = 10), yoga (n = 9) and hypnosis (n = 8). Slightly over half (47/84) of studies used a RCT design. The interventions were mainly (46/84) conducted in groups and most (51/84) included daily individual home practice. All but two studies were unblinded to participants.

CONCLUSION

The amount of available research on mind-body practices varies by practice. Almost half of the studies in this review were at high risk of bias. However, mindfulness, a combination of least three relaxation techniques and cognitive behavioral strategies, and yoga show encouraging results in decreasing physical and psychological symptoms and improving quality of life and health in people living with HIV. More rigorous studies are necessary to confirm the results of Tai Chi, Qigong, and some relaxation techniques.

Buffering Internalization of HIV Stigma: Implications for Treatment Adherence and Depression

BACKGROUND

One mechanism through which social stigma of HIV affects health outcomes for people living with HIV (PLWH) is through internalization of stigma. However, this transformation of social stigma in the community into internalized stigma may not be of the same magnitude for all PLWH. We examined the moderating effects of 3 personality traits-fear of negative social evaluation, attachment-related anxiety, and dispositional resilience-in transforming perceived stigma in the community into internalized stigma. Furthermore, we investigated downstream effects of these moderated associations on depressive symptoms and antiretroviral treatment (ART) adherence.

SETTING/METHODS

In study 1, data from 203 PLWH in the Southeast United States were analyzed controlling for age, sex, education, race, and time on ART. In study 2, data from 453 women in a multisite study were analyzed controlling for age, education, race, time on ART, and substance use.

RESULTS

In both studies, fear of negative evaluation and attachment-related anxiety moderated the effect of perceived HIV stigma in the community on internalized HIV stigma: People higher on those moderating variables had stronger associations between perceived stigma in the community and internalized stigma. In study 2, resilience was assessed and also moderated the effect of perceived HIV stigma in the community on internalized stigma. In moderated mediation models, fear of negative evaluation, attachment-related anxiety, and resilience moderated the indirect effect of perceived HIV stigma in the community on ART adherence and depression through internalized stigma.

CONCLUSIONS

Interventions to assuage internalization of HIV stigma should focus on bolstering attachment-related security, social competence, and resilience.

The scientific pursuit of sexual and gender minority mental health treatments: Toward evidence-based affirmative practice

The time has arrived for psychological science to translate the accumulating empirical research regarding sexual and gender minority (SGM) mental health into evidence-based affirmative treatments for this population. Far from the unscientific, homophobic theories of the early 20th century, several recent efforts in psychological science are starting to pave the way for evidence-based SGM-affirmative mental health treatments. These efforts include (a) identifying clear treatment targets for SGM, (b) conducting treatment studies that test the efficacy of therapy for SGM populations, (c) increased reporting of sexual orientation and gender diversity in existing randomized controlled trials conducted with the general population, and (d) reducing stigma itself, which has heretofore impeded the resources necessary to produce scientific evidence about SGM-affirmative treatments. This article reviews this progress and outlines future research directions needed to advance evidence-based practice for SGM, including determining whether and how existing evidence-based treatments need to be adapted to address SGM-specific concerns, why SGM-affirmative treatments work, and for whom and under what conditions SGM-affirmative treatments work best. A program of research is described that attempts to address these questions through randomized controlled trials with strong comparison conditions, psychotherapy process research of current SGM-affirmative practice, and tests of treatment moderators. To the extent that the mental health profession continues to pursue these solutions, it can ensure the continued flourishing of this population, whose visibility and vibrancy likely represent the surest route toward improving public acceptance and therefore its future mental health.

Effects of liver depression and psychological stress on human uterine leiomyoma cells by an AR-cAMP-PKA signal transduction pathway

OBJECTIVE

Based on the emotional theory of Traditional Chinese Medicine, and combined with the modern medicine theory of psychological stress, a research model of human uterine leiomyoma cells (ULM) was cultured in vitro to determine the effectiveness of adrenergic receptor (AR) agonists in human ULM cell growth. In addition, we studied the functional influence of "liver depression and psychological stress theory" on fibroid formation by intervening in the AR-cAMP-PKA signaling pathway. The intention was to establish a new method to prevent and cure fibroids through "liver depression and psychological stress theory" and provide an experimental basis for the Traditional Chinese Medicine emotional theory.

MATERIALS AND METHODS

Primary human ULM cells were enriched by collagenase digestion. Immunohistochemistry and hematoxylin and eosin (HE) staining were used for cytological identification. Using this model, we studied intervention using specific AR agonists on ULM cells to observe the influence of "liver depression and psychological stress theory" on estrogen receptor (ER), progesterone receptor (PR), vascular endothelial growth factor (VEGF) and fibroblast growth factors (FGF).

RESULTS

Norepinephrine (NE) and epinephrine (E) are adrenergic receptor agonists. They promoted ULM cell proliferation and increased the levels of ER, PR, VEGF and FGF. In contrast, isoproterenol (ISO) inhibited ULM cell proliferation and decreased the levels of ER, PR, VEGF and FGF. The protein expression of cAMP and PKA in ULM cells was reduced and the levels of ER, PR, VEGF and FGF were increased when co-treatment with the α-AR blocker (phentolamine). The β-AR blocker (metoprolol) displayed an opposite effect.

CONCLUSIONS

AR agonists modulated ER, PR, VEGF and FGF levels in ULM cells in an AR-cAMP-PKA-dependent signaling pathways to influence fibroid occurrence and development.

Nurse led home-based care for people with HIV/AIDS

BACKGROUND

Home-based care is used in many countries to increase quality of life and limit hospital stay, particularly where public health services are overburdened. Home-based care objectives for HIV/AIDS can include medical care, delivery of antiretroviral treatment and psychosocial support. This review assesses the effects of home-based nursing on morbidity in people infected with HIV/AIDS.

METHODS

The trials studied are in HIV positive adults and children, regardless of sex or setting and all randomised controlled. Home-based care provided by qualified nurses was compared with hospital or health-facility based treatment. The following electronic databases were searched from January 1980 to March 2015: AIDSearch, CINAHL, Cochrane Register of Controlled Trials, EMBASE, MEDLINE and PsycINFO/LIT, with an updated search in November 2016. Two authors independently screened titles and abstracts from the electronic search based on the study design, interventions and types of participant. For all selected abstracts, full text articles were obtained. The final study selection was determined with use of an eligibility form. Data extraction was performed independently from assessment of risk of bias. The results were analysed by narrative synthesis, in order to be able to obtain relevant effect measures plus 95% confidence intervals.

RESULTS

Seven studies met the inclusion criteria. The trial size varied from 37 to 238 participants. Only one trial was conducted in children. Five studies were conducted in the USA and two in China. Four studies looked at home-based adherence support and the rest at providing home-based psychosocial support. Reported adherence to antiretroviral drugs improved with nurse-led home-based care but did not affect viral load. Psychiatric nurse support in those with existing mental health conditions improved mental health and depressive symptoms. Home-based psychological support impacted on HIV stigma, worry and physical functioning and in certain cases depressive symptoms.

CONCLUSIONS

Nurse-led home-based interventions could help adherence to antiretroviral therapy and improve mental health. Further larger scale studies are needed, looking in more detail at improving medical care for HIV, especially related to screening and management of opportunistic infections and co-morbidities.

Psychological Distress Mediates the Effect of Alexithymia on 2-Year Change in HIV Viral Load

PURPOSE

Individuals with trait alexithymia (AL) display poor cognitive assimilation of thoughts, feelings, and emotions. This may result in the persistence of stress, anxiety, and depressive disorders. The cumulative effect of this psychological distress is also linked clinical markers of human immunodeficiency virus (HIV) disease progression. This study examines the indirect effect of AL on HIV viral load as a function of baseline levels and change in psychological distress.

METHODS

N = 123 HIV positive adults aged 37.9 ± 9.2 years provided blood samples for HIV-1 viral RNA and CD4 T lymphocytes along with self-reported stress, anxiety, and depression every 6 months for 2 years. A second-order conditional latent growth model was used to represent baseline and 2-year change in cumulative levels of psychological distress and to test the indirect effect of baseline levels of trait AL on change in HIV-1 viral load through this latent measure.

RESULTS

AL was associated with baseline and latent change in psychological distress. Furthermore, baseline psychological distress predicted 2-year change in HIV-1 viral RNA after controlling for viral load at baseline. Altogether, trait AL had a significant indirect effect on change in viral load (β = 0.16, p = 0.03) as a function of baseline levels of distress.

CONCLUSION

Identification and communication of thoughts, feelings, and emotions are important for long-term psychological adaptation in HIV. Greater psychological distress, in turn, allows for persistence of peripheral viral replication.

Telephone-Delivered Mindfulness Training for People Living with HIV: A Qualitative 360° Inquiry

For people living with HIV and AIDS (PLWHA), life stress often undermines quality of life and interferes with medical care. Mindfulness training (MT) may help PLWHA to manage stress. Because standard MT protocols can be burdensome, we explored telephone delivery as a potentially more feasible approach. We used an innovative 360° qualitative inquiry to seek input regarding telephone-delivery of MT for PLWHA in advance of a planned intervention trial. We also sought input on a time- and attention-matched control. Twenty five HIV patients, providers and advocates, were recruited to five focus groups. Participants understood the construct of mindfulness and recognized its potential benefits for stress management and improving medication adherence. Patients preferred the term "mindfulness" to meditation. Telephone-delivery appealed to all patients but several challenges were raised. Topics for the control intervention included nutrition, sleep, and aging. The 360° approach allowed three groups (patients, providers, advocates) to influence intervention development.

Impact of stressful death or divorce in people with HIV: A prospective examination and the buffering effects of religious coping and social support

This study examined the impact of a stressful death/divorce on psychological and immune outcomes in people with HIV. People with HIV with stressful death/divorce were examined from before the event to up to 12 months later (n = 45); controls were assessed at similar intervals (n = 112). Stressful deaths/divorces were associated with increased viral load and anxiety over time (ps ≤ .014), but not CD4+ or depression. Increased use of religious coping after the stressful death/divorce was associated with slower increases in viral load (p = .010). These data suggest people with HIV should consider the potentially elevated risk of transmission after such events and seek appropriate monitoring and care.

The effects of psychological interventions on wound healing: A systematic review of randomized trials

PURPOSE

Psychological stress has been shown to delay wound healing. Several trials have investigated whether psychological interventions can improve wound healing, but to date, this evidence base has not been systematically synthesized. The objective was to conduct a systematic review of randomized controlled trials in humans investigating whether psychological interventions can enhance wound healing.

METHODS

A systematic review was performed using PsychINFO, CINAHL, Web of Science, and MEDLINE. The searches included all papers published in English up until September 2016. The reference lists of relevant papers were screened manually to identify further review articles or relevant studies. Nineteen studies met inclusion criteria and were included in the review.

RESULTS

Fifteen of nineteen studies were of high methodological quality. Six studies were conducted with acute experimentally created wounds, five studies with surgical patients, two studies with burn wounds, two studies with fracture wounds, and four studies were conducted with ulcer wounds. Post-intervention standardized mean differences (SMD) between groups across all intervention types ranged from 0.13 to 3.21, favouring improved healing, particularly for surgical patients and for relaxation interventions. However, there was some evidence for publication bias suggesting negative studies may not have been reported. Due to the heterogeneity of wound types, population types, and intervention types, it is difficult to pool effect sizes across studies.

CONCLUSIONS

Current evidence suggests that psychological interventions may aid wound healing. Although promising, more research is needed to assess the efficacy of each intervention on different wound types. Statement of contribution What is already known on this subject? Psychological stress negatively affects wound healing. A number of studies have investigated whether psychological interventions can improve healing. However, no systematic reviews have been conducted. What does this study add? Synthesis and review of 19 trials conducted on psychological interventions and wound healing. Most evidence supports improved healing, particularly for surgical wounds and relaxation interventions. More research is needed on different intervention types with clinical wounds and into mechanisms of action.

A Systematic Review of Gay, Lesbian, and Bisexual Research Samples in Couple and Family Therapy Journals

The purpose of this study is to review samples from research on gay, lesbian, and bisexual (GLB) issues and to evaluate the suitability of this body of research to support affirmative and evidence-based practice with GLB clients. The authors systematically reviewed the sampling methodology and sample composition of GLB-related research. All original, quantitative articles focusing on GLB issues published in couple and family therapy (CFT)-related journals since 1975 were coded (n = 153). Results suggest that within the GLB literature base there is some evidence of heterocentrism as well as neglect of issues of class, race, and gender. Suggestions to improve the diversity and representativeness of samples-and, thus, clinical implications-of GLB-related research in CFT literature are provided.

Psychosocial group interventions to improve psychological well-being in adults living with HIV

BACKGROUND

Being diagnosed with human immunodeficiency virus (HIV), and labelled with a chronic, life-threatening, and often stigmatizing disease, can impact on a person's well-being. Psychosocial group interventions aim to improve life-functioning and coping as individuals adjust to the diagnosis.

OBJECTIVES

To examine the effectiveness of psychosocial group interventions for improving the psychological well-being of adults living with HIV/AIDS.

SEARCH METHODS

We searched the following electronic databases up to 14 March 2016: the Cochrane Central Register of Controlled Trials (CENTRAL) published in the Cochrane Library (Issue 2, 2016), PubMed (MEDLINE) (1996 to 14 March 2016), Embase (1996 to 14 March 2016), and Clinical Trials.gov.

SELECTION CRITERIA

Randomized controlled trials (RCTs) or quasi-RCTs that compared psychosocial group interventions with versus control (standard care or brief educational interventions), with at least three months follow-up post-intervention. We included trials that reported measures of depression, anxiety, stress, or coping using standardized scales.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened abstracts, applied the inclusion criteria, and extracted data. We compared continuous outcomes using mean differences (MD) with 95% confidence intervals (95% CIs), and pooled data using a random-effects model. When the included trials used different measurement scales, we pooled data using standardized mean difference (SMD) values. We reported trials that we could not include in the meta analysis narratively in the text. We assessed the certainty of the evidence using the GRADE approach.

MAIN RESULTS

We included 16 trials (19 articles) that enrolled 2520 adults living with HIV. All the interventions were multifaceted and included a mix of psychotherapy, relaxation, group support, and education. The included trials were conducted in the USA (12 trials), Canada (one trial), Switzerland (one trial), Uganda (one trial), and South Africa (one trial), and published between 1996 and 2016. Ten trials recruited men and women, four trials recruited homosexual men, and two trials recruited women only. Interventions were conducted with groups of four to 15 people, for 90 to 135 minutes, every week for up to 12 weeks. All interventions were conducted face-to-face except two, which were delivered by telephone. All were delivered by graduate or postgraduate trained health, psychology, or social care professionals except one that used a lay community health worker and two that used trained mindfulness practitioners.Group-based psychosocial interventions based on cognitive behavioural therapy (CBT) may have a small effect on measures of depression, and this effect may last for up to 15 months after participation in the group sessions (SMD -0.26, 95% CI -0.42 to -0.10; 1139 participants, 10 trials, low certainty evidence). Most trials used the Beck Depression Inventory (BDI), which has a maximum score of 63, and the mean score in the intervention groups was around 1.4 points lower at the end of follow-up. This small benefit was consistent across five trials where participants had a mean depression score in the normal range at baseline, but trials where the mean score was in the depression range at baseline effects were less consistent. Fewer trials reported measures of anxiety, where there may be little or no effect (four trials, 471 participants, low certainty evidence), stress, where there may be little or no effect (five trials, 507 participants, low certainty evidence), and coping (five trials, 697 participants, low certainty evidence).Group-based interventions based on mindfulness have not demonstrated effects on measures of depression (SMD -0.23, 95% CI -0.49 to 0.03; 233 participants, 2 trials, very low certainty evidence), anxiety (SMD -0.16, 95% CI -0.47 to 0.15; 62 participants, 2 trials, very low certainty evidence), or stress (MD -2.02, 95% CI -4.23 to 0.19; 137 participants, 2 trials, very low certainty evidence). No mindfulness based interventions included in the studies had any valid measurements of coping.

AUTHORS' CONCLUSIONS

Group-based psychosocial interventions may have a small effect on measures of depression, but the clinical importance of this is unclear. More high quality evidence is needed to assess whether group psychosocial intervention improve psychological well-being in HIV positive adults.

Change in urinary cortisol excretion mediates the effect of angry/hostile mood on 9 month diastolic blood pressure in HIV+ adults

Cardiovascular disease is a growing concern in HIV disease management and nearly 1 out of 3 persons living with the virus is hypertensive. Biobehavioral factors such as anger, hostility, and HPA axis reactivity are emperically linked to blood pressure regulation. Whether HPA axis or mood disturbance increases risk for hypertension remains unclear in HIV disease. The aim of this study was to determine whether 9-month change in angry/hostile mood predicts alterations in systolic (SBP) or diastolic blood pressure (DBP), and whether this change is mediated by 24-h urinary cortisol (CORT) output. Sixty-one HIV positive adults, aged 41.1 ± 8.6 years, assigned to the control condition of a stress management intervention provided blood samples, 24-h urine specimens, blood pressure in-office, and self-reported mood at baseline and a 9-month follow-up. CORT was tested as a mediator in two separate models controlling for baseline BP, CD4 count, HIV-1 viral load, protease inhibitor use, body mass index, smoking status, and family history of cardiometabolic disease. Increase in angry/hostile mood was associated with greater SBP (β = 0.33, CI 0.09, 0.56, p = 0.01) and DBP (β = 0.39, CI 0.16, 0.62, p < 0.001) at follow-up. CORT partially mediated the effect of angry/hostile mood on DBP (β = 0.28, CI 0.03, 0.54, p = 0.03). Change in CORT was not related to SBP (β = 0.12, CI -0.20, 0.44, p = 0.46). The final mediation model accounted for 41.2% of the variance in 9-month DBP. Angry or hostile mood may contribute to increased risk for hypertension in persons treated for HIV via disturbance of the HPA-axis.

Untangling the Gordian knot of HIV, stress, and cognitive impairment

As individuals live longer with HIV, this "graying of the HIV epidemic" has introduced a new set of challenges including a growing number of age and inflammation-related diseases such as cardiovascular disease, type II diabetes, cancer, and dementia. The biological underpinnings of these complex and co-morbid diseases are not fully understood and become very difficult to disentangle in the context of HIV and aging. In the current review we examine the contributions and interactions of HIV, stress, and cognitive impairment and query the extent to which inflammation is the linchpin in these dynamic interactions. Given the inter-relatedness of stress, inflammatory mechanisms, HIV, and cognitive impairment, future work will either need to address multiple dimensions simultaneously or embrace the philosophy that breaking the aberrant cycle at any one point will subsequently remedy the other related systems and processes. Such a single-point intervention may be effective in early disease states, but after perpetuation of an aberrant cycle, adaptations in an attempt to internally resolve the issue will likely lead to the need for multifaceted interventions. Acknowledging that HIV, inflammation, and stress may interact with one another and collectively impact cognitive ability is an important step in fully understanding an individual's complete clinical picture and moving towards personalized medicine.

Group Interventions for Patients with Cancer and HIV Disease: Part III. Moderating Variables and Mechanisms of Action

Growing evidence supports the value of group interventions for individuals who are at risk for or have developed cancer or HIV disease. However, information is more limited concerning how these services can be delivered in an optimal manner, and what processes contribute to their benefits. Parts I and II of this review examined the efficacy of different interventions for individuals at different phases of illness, ranging from primary prevention to late-stage disease, in both psychosocial and biological domains. The current paper examines some of the factors other than phase of illness that might influence group treatment effects (e.g., intervention parameters, participant characteristics), and explores mechanisms of action.

Group Interventions for Patients with Cancer and HIV Disease: Part I: Effects on Psychosocial and Functional Outcomes at Different Phases of Illness

Group interventions for individuals facing cancer or HIV disease have drawn considerable attention among researchers and clinicians over the past 20 years. There is growing evidence that group services may be helpful, but which interventions are most effective for participants at which phases in the trajectory of disease has been less clear. Moreover, professionals working in different intervention settings (e.g., primary prevention vs. clinical care) and different disease sites (cancer vs. HIV disease) often have little awareness of relevant advances in other fields. Efforts to integrate findings in the literature may accelerate research and advance the standard of clinical care. The current article, the first in a series of four special reports, critically evaluates the efficacy of group interventions led by professional or trained facilitators for individuals confronted by cancer or HIV, across the spectrum of illness from elevated risk through advanced disease. We examine psychosocial and functional outcomes for different interventions directed toward different patient subgroups, trace common themes, highlight limitations, and offer recommendations for further research.

Psychosocial and Neurohormonal Predictors of HIV Disease Progression (CD4 Cells and Viral Load): A 4 Year Prospective Study

Most studies of psychosocial predictors of disease progression in HIV have not considered norepinephrine (NE), a neurohormone related to emotion and stress, even though NE has been related to accelerated viral replication in vitro and impaired response to antiretroviral therapy (ART). We therefore examined NE, cortisol, depression, hopelessness, coping, and life event stress as predictors of HIV progression in a diverse sample. Participants (n = 177) completed psychological assessment, blood draws [CD4, viral load (VL)], and a 15 h urine sample (NE, cortisol) every 6 months over 4 years. Hierarchical linear modeling (HLM) was used to model slope in CD4 and VL controlling for ART at every time point, gender, age, race, SES, and initial disease status. NE (as well as depression, hopelessness, and avoidant coping) significantly predicted a greater rate of decrease in CD4 and increase in VL. Cortisol was not significantly related to CD4, but predicted VL increase. To our knowledge, this is the first study relating NE, in vivo, to accelerated disease progression over an extended time. It also extends our previous 2 year study by relating depressed mood and coping to accelerated disease progression over 4 years.

The ABCs of Trait Anger, Psychological Distress, and Disease Severity in HIV

BACKGROUND

Trait anger consists of affective, behavioral, and cognitive (ABC) dimensions and may increase vulnerability for interpersonal conflict, diminished social support, and greater psychological distress. The concurrent influence of anger and psychosocial dysfunction on Human Immunodeficiency Virus (HIV) disease severity is unknown.

PURPOSE

The purpose of this study was to examine plausible psychosocial avenues (e.g., coping, social support, psychological distress), whereby trait anger may indirectly influence HIV disease status.

METHODS

Three hundred seventy-seven HIV seropositive adults, aged 18-55 years (58% AIDS-defined), completed a battery of psychosocial surveys and provided a fasting blood sample for HIV-1 viral load and T lymphocyte count assay.

RESULTS

A second-order factor model confirmed higher levels of the multidimensional anger trait, which was directly associated with elevated psychological distress and avoidant coping (p<.001) and indirectly associated with greater HIV disease severity (p<.01) (comparative fit index (CFI)=0.90, root-mean-square error of approximation (RMSEA)=0.06, standardized root-mean-square residual (SRMR)=0.06).

CONCLUSION

The model supports a role for the ABC components of anger, which may negatively influence immune function through various psychosocial mechanisms; however, longitudinal study is needed to elucidate these effects.

Future directions for interventions targeting PTSD in HIV-infected adults

Although studies consistently report high rates of comorbid posttraumatic stress disorder (PTSD) and HIV infection, development and testing of PTSD treatment interventions in HIV-infected adults is limited. As such, the purpose of this review was twofold. First, this review augments the three existing reviews of research for PTSD in HIV-infected adults conducted within the past 10 years. We found two empirically supported cognitive-behavioral therapy-based interventions for the treatment of trauma-related symptoms in HIV-infected adults. Due to the continued limited number of effective interventions for this population, a second aim of our review was to draw from the expansive field of effective PTSD interventions for the general population to propose ways that future clinical intervention research may be tailored for HIV-infected adults. Therefore, in addition to a review, we conceptualized this paper as an opportunity to generate an ideal preview of the field of intervention research in this population.

Relationships between dimensions of disability experienced by adults living with HIV: a structural equation model analysis

As individuals age with HIV it is increasingly important to consider the health-related consequences of HIV and multiple morbidities, known as disability. We assessed relationships between four dimensions of disability among adults living with HIV. We conducted a structural equation modeling analysis using data from 913 participants in the Ontario HIV Treatment Network Cohort Study to determine relationships between four latent variables of disability in the Episodic Disability Framework: physical symptoms and impairments, mental health symptoms and impairments, difficulties with day-to-day activities, and challenges to social inclusion. Results indicated that physical symptoms and impairments, mental health symptoms and impairments and difficulties with day-to-day activities directly or indirectly predicted challenges to social inclusion for adults living with HIV. Challenges to social inclusion were directly predicted by mental health symptoms and indirectly by physical health symptoms via (mediated by) having difficulties carrying out day-to-day activities and mental health symptoms and impairments. These findings provide a basis for conceptualizing disability experienced by people living with HIV.

Alexithymia is linked to neurocognitive, psychological, neuroendocrine, and immune dysfunction in persons living with HIV

The neuropathological changes resulting from Human Immunodeficiency Virus (HIV) infection may manifest in alexithymia (AL), a multidimensional trait characterized by impairments in the cognitive assimilation of feelings and emotions. A sample of 93 HIV survivors scoring high, i.e., ⩾74 on the 26-item Toronto Alexithymia Scale (TAS-26), were compared to 79 low AL (TAS-26⩽54) survivors on measures of neurocognitive, psychological, neuroendocrine and immune function. Neurocognitive function was evinced by a standardized test of psychomotor speed, cognitive flexibility and task switching ability, HIV Dementia and general cognitive status. Patients were also screened for levels of depression, anxiety and psychological stress. A 24-h urinary norepinephrine (NE) and cortisol (CORT) collection was taken; blood was drawn for T lymphocyte subset counts (CD4+CD3+) and HIV-1 viral load. Alexithymic patients exhibited higher levels of executive dysfunction, psychological distress, norepinephrine-to-cortisol (NE/CORT) ratio and viral load. Linear regression models accounting for sociodemographic and disease-related variables revealed two AL subscales, difficulties identifying and describing feelings, predicted and explained a significant proportion of variance in the outcome measures. Specifically, poorer executive task-switching/cognitive flexibility was associated with greater difficulty describing feelings; dysregulated autonomic response (high NE/CORT ratio) and depressive symptoms were predicted by difficulty identifying feelings; higher levels of anxiety and psychological stress were both predicted by greater difficulty describing and identifying feelings. Overall, the psychoneuroimmunological profile of alexithymia in HIV positive persons at mid-stage of infection suggests a greater vulnerability for disease progression.

Effects of guided imagery on biobehavioral factors in women with fibromyalgia

Women diagnosed with fibromyalgia (N = 72) participated in a 10-week randomized trial to examine the effectiveness of guided imagery on self-efficacy, perceived stress, and selected biobehavioral factors (FMS symptoms; immune biomarkers). Participants in both guided imagery and usual care control conditions completed measures and donated 3 cc of blood at baseline, 6- and 10-weeks. A mixed effects linear model to test for differences between groups for all behavioral and biologic variables demonstrated that after 10 weeks of daily intervention use, guided imagery participants reported statistically significant increases in self-efficacy and statistically significant decreases in stress, fatigue, pain, and depression. There were no statistically significant changes in biomarker levels, although total group C-reactive protein was elevated at baseline (4.7 mg/L), indicating an inflammatory process. Subsequent studies should be undertaken to more fully elucidate the biobehavioral aspects of nonpharmacological intervention effectiveness.

A sexual risk and stress reduction intervention designed for HIV-positive bisexual African American men with childhood sexual abuse histories

OBJECTIVES

HIV transmission risk is high among men who have sex with men and women (MSMW), and it is further heightened by a history of childhood sexual abuse (CSA) and current traumatic stress or depression. Yet, traumatic stress is rarely addressed in HIV interventions. We tested a stress-focused sexual risk reduction intervention for African American MSMW with CSA histories.

METHODS

This randomized controlled trial compared a stress-focused sexual risk reduction intervention with a general health promotion intervention. Sexual risk behaviors, psychological symptoms, stress biomarkers (urinary cortisol and catecholamines), and neopterin (an indicator of HIV progression) were assessed at baseline and at 3- and 6-month follow-ups.

RESULTS

Both interventions decreased and sustained reductions in sexual risk and psychological symptoms. The stress-focused intervention was more efficacious than the general health promotion intervention in decreasing unprotected anal insertive sex and reducing depression symptoms. Despite randomization, baseline group differences in CSA severity, psychological symptoms, and biomarkers were found and linked to subsequent intervention outcomes.

CONCLUSIONS

Although interventions designed specifically for HIV-positive African American MSMW can lead to improvements in health outcomes, future research is needed to examine factors that influence intervention effects.

Does music influence stress in mechanically ventilated patients?

OBJECTIVES

Mechanically ventilated patients experience profound stress. Interventions are needed to ameliorate stress that does not cause adverse effects. The purpose of this study was to explore the influence of music on stress in a sample of patients over the duration of ventilatory support.

RESEARCH METHODOLOGY/DESIGN

Randomised controlled trial; randomised patients (56.8+16.9 years, 61% male, APACHE III 57.2+18.3) receiving ventilatory support to: (1) patient-directed music (PDM) where patients self-initiated music listening whenever desired from a preferred collection, (2) headphones only to block ICU noise, or (3) usual ICU care. Twenty-four hour urinary cortisol samples were collected from a sub-set of subjects with intact renal function and not receiving medications known to influence cortisol levels (n=65).

SETTING

12 ICUs in the Midwestern United States.

MAIN OUTCOME MEASURES

Urinary free cortisol (UFC), an integrative biomarker of stress.

RESULTS

Controlling for illness severity, gender, and baseline UFC (29-45 mg/day), mixed models analysis revealed no significant differences among groups in UFC over the course of ventilatory support.

CONCLUSION

While music did not significantly reduce cortisol, less profound spikes in UFC levels were observed but that, given the limitations of the research, this observation could have occurred merely by chance.

Auditory hallucinations: expectation-perception model

In this paper, we aimed to present a hypothesis that would explain the mechanism of auditory hallucinations, one of the main symptoms of schizophrenia. We propose that auditory hallucinations arise from abnormalities in the predictive coding which underlies normal perception, specifically, from the absence or attenuation of prediction error. The suggested deficiencies in processing prediction error could arise from (1) abnormal modulation of thalamus by prefrontal cortex, (2) absence or impaired transmission of external input, (3) dysfunction of the auditory and association cortex, (4) neurotransmitter dysfunction and abnormal connectivity, and (5) hyperactivity activity in auditory cortex and broad prior probability. If there is no prediction error, the initially vague prior probability develops into an explicit percept in the absence of external input, as a result of a recursive pathological exchange between auditory and prefrontal cortex. Unlike existing explanations of auditory hallucinations, we propose concrete mechanisms which underlie the imbalance between perceptual expectation and external input. Impaired processing of prediction error is reflected in reduced mismatch negativity and increased tendency to report non-existing meaningful language stimuli in white noise, shown by those suffering from auditory hallucinations. We believe that the expectation-perception model of auditory hallucinations offers a comprehensive explanation of the underpinnings of auditory hallucinations in both patients and those not diagnosed with mental illness. Therefore, our hypothesis has the potential to fill the gaps in the existing knowledge about this distressing phenomenon and contribute to improved effectiveness of treatments, targeting specific mechanisms.

Cognitive-behavioral stress management reverses anxiety-related leukocyte transcriptional dynamics

BACKGROUND

Chronic threat and anxiety are associated with pro-inflammatory transcriptional profiles in circulating leukocytes, but the causal direction of that relationship has not been established. This study tested whether a cognitive-behavioral stress management (CBSM) intervention targeting negative affect and cognition might counteract anxiety-related transcriptional alterations in people confronting a major medical threat.

METHODS

One hundred ninety-nine women undergoing primary treatment of stage 0-III breast cancer were randomized to a 10-week CBSM protocol or an active control condition. Seventy-nine provided peripheral blood leukocyte samples for genome-wide transcriptional profiling and bioinformatic analyses at baseline, 6-month, and 12-month follow-ups.

RESULTS

Baseline negative affect was associated with >50% differential expression of 201 leukocyte transcripts, including upregulated expression of pro-inflammatory and metastasis-related genes. CBSM altered leukocyte expression of 91 genes by >50% at follow-up (group × time interaction), including downregulation of pro-inflammatory and metastasis-related genes and upregulation of type I interferon response genes. Promoter-based bioinformatic analyses implicated decreased activity of NF-κB/Rel and GATA family transcription factors and increased activity of interferon response factors and the glucocorticoid receptor as potential mediators of CBSM-induced transcriptional alterations.

CONCLUSIONS

In early-stage breast cancer patients, a 10-week CBSM intervention can reverse anxiety-related upregulation of pro-inflammatory gene expression in circulating leukocytes. These findings clarify the molecular signaling pathways by which behavioral interventions can influence physical health and alter peripheral inflammatory processes that may reciprocally affect brain affective and cognitive processes.

Stress reduction through psychoeducation: a meta- analytic review

The aim of this meta-analysis was to evaluate the effectiveness of psychoeducational interventions in reducing stress and to gain more insight in determining features moderating the magnitude of effects. Relevant studies were selected from 1990 to 2010 and were included according to predetermined criteria. For each study, the standardized mean difference was calculated for the outcome measure primarily related to stress. Nineteen studies met the inclusion criteria; for 16 studies, a standardized mean difference could be calculated. The average effect size was .27 (95% confidence interval = [.14, .40]) at posttest and .20 (95% confidence interval = [-.04, .43]) at follow-up. To determine possible moderators of intervention effects, all 19 studies were included. Only interventions that were shorter in duration provided better results. When a model with multiple moderators was considered, a model combining both intervention duration and the number of women in an intervention was significant and accounted for 42% of the variability found in the data set. Specifically, interventions with more women that were shorter in duration obtained better results.

School-Based Intervention: Relaxation and Guided Imagery for Students With Asthma and Anxiety Disorder

This school-based study analyzed the impact of RGI on lung functioning (forced expiratory volume in 1 s [FEV1] and forced expiratory flow 25-75 [FEF25-75]) and by employing a multiple baseline design across 3 high school students with asthma and clinically diagnosed anxiety disorders. The RGI intervention took place for a 20-min period, an average of three times per week, over a 4-week period. At the onset of the intervention, it was found that lung functioning, particularly FEV1 increased in all 3 participants, with effect sizes ranging from —.32 to —2.48. FEF25-75 improved in one of the participants. In addition, a positive impact was also seen in the lowering of anxiety scores across all 3 participants, with effect sizes ranging from .12 to 1.69.

Insulin resistance, obesity, inflammation, and depression in polycystic ovary syndrome: biobehavioral mechanisms and interventions

OBJECTIVE

To summarize physiological and psychological characteristics that are common among women diagnosed with polycystic ovary syndrome (PCOS) and provide evidence suggesting that addressing psychological disturbances can reduce or alleviate physical symptoms of PCOS through behavioral pathways and physiological pathways.

METHOD(S)

Empirical studies and expert consensuses pertaining to physiological, psychological, and medical management aspects of PCOS were identified and presented in this review. Articles were identified by searching Pubmed, PsycInfo, Medline ISI, CINAHL, or a Web browser (i.e., Google) using numerous combinations of terms pertaining to physiological, psychological, and medical management aspects of PCOS. An article was chosen to be included in this review if it reported findings and/or provided information that related to and helped support the main purpose(s) of this review article.

RESULT(S)

Available literature on the physiological (i.e., hyperandrogenism, central obesity, inflammation, insulin resistance) and psychological (i.e., depression, anxiety, eating disorders) factors among women with PCOS provides evidence that these various aspects of PCOS are strongly interrelated.

CONCLUSION(S)

The existence of these relationships among physiological and psychological factors strongly suggests that medical management of PCOS would greatly benefit from inclusion of psychological and behavioral approaches.

Mechanisms of change in negative thinking and urinary monoamines in depressed patients during acute treatment with group cognitive behavior therapy and antidepressant medication

This naturalistic study investigated the mechanisms of change in measures of negative thinking and in 24-h urinary metabolites of noradrenaline (norepinephrine), dopamine and serotonin in a sample of 43 depressed hospital patients attending an eight-session group cognitive behavior therapy program. Most participants (91%) were taking antidepressant medication throughout the therapy period according to their treating Psychiatrists' prescriptions. The sample was divided into outcome categories (19 Responders and 24 Non-responders) on the basis of a clinically reliable change index [Jacobson, N.S., & Truax, P., 1991.

CLINICAL SIGNIFICANCE

a statistical approach to defining meaningful change in psychotherapy research. Journal of Consulting and Clinical Psychology, 59, 12-19.] applied to the Beck Depression Inventory scores at the end of the therapy. Results of repeated measures analysis of variance [ANOVA] analyses of variance indicated that all measures of negative thinking improved significantly during therapy, and significantly more so in the Responders as expected. The treatment had a significant impact on urinary adrenaline and metadrenaline excretion however, these changes occurred in both Responders and Non-responders. Acute treatment did not significantly influence the six other monoamine metabolites. In summary, changes in urinary monoamine levels during combined treatment for depression were not associated with self-reported changes in mood symptoms.

Home-based care for reducing morbidity and mortality in people infected with HIV/AIDS

BACKGROUND

Home-based care (HBC), to promote quality-of-life and limit hospital care, is used in many countries, especially where public health services are overburdened.

OBJECTIVES

This review assessed the effects of HBC on morbidity and mortality in those with HIV/AIDS.

SEARCH STRATEGY

Randomised and controlled clinical trials of HBC including all forms of treatment, care and support offered in the home were included. A highly sensitive search strategy was used to search CENTRAL, MEDLINE, EMBASE, AIDSearch, CINAHL, PsycINFO/LIT. Risk of bias of all trials was assessed.

SELECTION CRITERIA

All randomised and controlled clinical trials were included of HIV/AIDS positive individuals, adults and children, of any gender, and from any setting. Home-based care, provided by family, lay and/or professional people, including all forms of treatment, care and support offered in the HIV/AIDS positive person's home as compared to hospital or institutional based care

DATA COLLECTION AND ANALYSIS

Titles, abstracts and descriptor terms of the electronic search results were screened independently by two authors for relevance based on the types of participants, interventions, and study design. Full text articles were obtained of all selected abstracts and an eligibility form was used to determine final study selection. Data extraction and assessment of risk of bias were done independently. Narrative synthesis of results were done. Relevant effect measures and the 95% confidence intervals were reported.

MAIN RESULTS

Ten studies randomised individuals and trial sizes varied from n=31 to n=549. One study randomised 392 households and enrolled a total of 509 persons with HIV and 1,521 HIV-negative household members. Two ongoing studies were identified. Intensive home-based nursing significantly improved self-reported knowledge of HIV and medications, self-reported adherence and difference in pharmacy drug refill (1 study). Another study, comparing proportion of participants with greater than 90% adherence, found statistically significant differences over time but no significant change in CD4 counts and viral loads. A third study found significant differences in HIV stigma, worry and physical functioning but no differences in depressive symptoms, mood, general health, and overall functioning. Comprehensive case management by trans-professional teams compared to usual care by primary care nurses had no significant difference in quality-of-life after 6-months of follow-up (n=57) and average length of time on service (n=549). Home total parenteral nutrition had no significant impact on overall survival and rate of re-hospitalisation. Two trials comparing computers with brochures/nothing/standard medical care found no significant effect on health status, and decision-making confidence and skill, but a reduction in social isolation after controlling for depression. Two trials evaluating home exercise programmes found opposing results. Home-based safe water systems reduced diarrhea frequency and severity among persons with HIV in Africa.

AUTHORS' CONCLUSIONS

Studies were generally small and very few studies were done in developing countries. There was a lack of studies truly looking at the effect of home based care itself or looking at significant end points (death and progression to AIDS). However, the range of interventions and HBC models evaluated can assist in making evidence-based decisions about HIV care and support.

Psycho-Immunological Effects of Written Emotional Disclosure During Long-Term Injury Rehabilitation

Psychological trauma associated with long-term injury can cause athletes to experience intense stress-like symptoms and considerable negative affect (e.g., Tracey, 2003; Udry, 1997). Due to the nature of competitive sport, however, it is thought that injured athletes inhibit these emotions to the detriment of their physical health. The present study examined Pennebaker’s (1989) emotional disclosure paradigm within a sporting context. It was hypothesized that writing about a traumatic injury would reduce athletes’ mood disturbance and stress during rehabilitation. Further, it was believed that these changes would correspond with an increase in immune expression from pre- to postintervention. Elite injured athletes (N = 9) rehabilitating from anterior cruciate ligament surgery participated in the 3-day writing intervention, consisting of 3 X 20 min writing sessions, during which athletes disclosed negative emotions associated with their injury and rehabilitation experiences. Measures were taken at six time-points (T1-T6), with pre- and postintervention phases lasting for 4 weeks each. Measures consisted of psychological stress (intrusion and avoidance), total mood disturbance, and relative cell-counts/µL for circulating T-cells (CD4/8) and NK cells (CD16/56). Repeated-measures ANOVAs showed a signifcant main effect of time for intrusion, F(5, 70) = 5.83, p =.001, η2 = .29 and avoidance, F(5, 70) = 5.73, p =.002, η2 = 0.29 subscales; mood disturbance, F(5, 70) = 3.71, p= 0.005, η2 = 0.21; and CD4+, F(5, 65) = 2.39, p= 0.048, η2 = .16. Subsequent linear contrasts provided further evidence of significant prepost differences among the stress, mood state, and immune variables. These results suggest that the written disclosure intervention has potential psycho-immunological benefits for athletes rehabilitating from long-term injury.

Public health significance of neuroticism

The personality trait of neuroticism refers to relatively stable tendencies to respond with negative emotions to threat, frustration, or loss. Individuals in the population vary markedly on this trait, ranging from frequent and intense emotional reactions to minor challenges to little emotional reaction even in the face of significant difficulties. Although not widely appreciated, there is growing evidence that neuroticism is a psychological trait of profound public health significance. Neuroticism is a robust correlate and predictor of many different mental and physical disorders, comorbidity among them, and the frequency of mental and general health service use. Indeed, neuroticism apparently is a predictor of the quality and longevity of our lives. Achieving a full understanding of the nature and origins of neuroticism, and the mechanisms through which neuroticism is linked to mental and physical disorders, should be a top priority for research. Knowing why neuroticism predicts such a wide variety of seemingly diverse outcomes should lead to improved understanding of commonalities among those outcomes and improved strategies for preventing them.

Effects of faith/assurance on cortisol levels are enhanced by a spiritual mantram intervention in adults with HIV: a randomized trial

OBJECTIVES

Previous research among HIV-infected individuals suggests that spiritual well-being is inversely related to psychological distress and rates of disease progression. Use of a mantram, a spiritual word or phrase repeated frequently and silently throughout the day, has been associated with decreased psychological distress and increased spiritual well-being. This study compared the effects of 2 interventions-a spiritually-based mantram intervention versus an attention-matched control group-on faith/assurance and average salivary cortisol levels among HIV-infected individuals.

METHODS

Using a randomized design, HIV-infected adults were assigned to the intervention (n = 36) or control condition (n = 35). Faith scores and saliva (collected at 7 a.m., 11 a.m., 4 p.m., and 9 p.m.) were assessed at preintervention, postintervention, and 5-week follow-up. Path analyses tested competing models that specify both concurrent and sequential relationships between faith and average daily cortisol levels while comparing groups.

RESULTS

Faith levels increased among mantram participants from pre- to postintervention. Greater faith at preintervention was significantly associated with lower average cortisol at postintervention in the mantram group but not in the controls. The associations between faith at postintervention and cortisol levels at 5-week follow-up were significant among both groups but weaker than the pre- to postintervention association identified in the mantram group.

CONCLUSIONS

These results suggest the presence of lagged or antecedent consequent relationships between faith and cortisol, which may be enhanced by mantram use. Decreased cortisol could potentially benefit immune functioning among HIV-infected individuals.
