ABSTRACT

Forcibly displaced Muslims, including refugees, internally displaced persons, and asylum seekers who have fled their homes to escape violence, conflict, and persecution, often have inequitable access to quality mental health services, despite substantial trauma exposure and high rates of posttraumatic stress disorder (PTSD). Understanding factors associated with domains of perceived need (i.e., community, individual, friends/family) for culturally-responsive, trauma-focused mental health interventions among forcibly displaced Muslims may provide insight into those most likely to seek psychological treatment. A sample of 108 forcibly displaced Muslims endorsed moderate to high perceived need across all three domains for a trauma healing group tailored for Muslim refugees. PTSD severity related to perceived individual need, regardless of locus of displacement. Among participants with minimal PTSD symptoms, those who were externally displaced had higher perceived community and friends or family need than those who were internally displaced. Findings highlight a need for culturally responsive, trauma-focused mental health services to facilitate access to mental health care for forcibly displaced Muslims.

ABSTRACT

INTRODUCTION: Among trauma-exposed, forcibly displaced Muslims, very little is known about how social connectedness, or perceived interpersonal connection and belonging, may alter the relationship between discrimination and negative posttraumatic cognitions. Discrimination may aggravate trauma psychopathology (Helms et al., 2010); however, social connectedness may buffer its negative effects (Juang & Alvarez, 2010). OBJECTIVE: We examined whether higher religious and racial/ethnic discrimination would be associated with stronger negative posttraumatic cognitions and whether stronger social connectedness may adaptively buffer this relationship. METHOD: Trauma exposed individuals (N = 99) who identified as Muslim and as a refugee, asylum seeker, or internally displaced person participated in the study. Measures of discrimination, social connection, and posttraumatic cognitions were completed. RESULTS: Higher discrimination was moderately associated with stronger negative trauma-related cognitions (r = .40, p < .001) and with lower social connectedness (r = -.32, p = .001). Social connectedness moderated the relationship between discrimination and posttraumatic cognitions, such that at lower levels of social connectedness there was a stronger relationship between discrimination and posttraumatic cognitions (-2SD: b = .32, -1SD: b = .23, M: b = .14), this was not present at higher levels of social connectedness. CONCLUSIONS: Connectedness to one's minority group may be an important protective factor by modulating the effects of discrimination on posttrauma adjustment.

ABSTRACT

SIGNIFICANCE: Multiple vision-related quality of life (VRQol) instruments exist, but questionnaires designed specifically for myopic children that are appropriate for assessing the impact of refractive error are rare. PURPOSE: This study aimed to assess the validity and reliability of the Student Refractive Error and Eyeglasses Questionnaire - Revised (SREEQ-R) in school-aged children with myopia in the United Kingdom. METHODS: Community optometrists in the United Kingdom invited children up to the age of 18 years presenting for an eye examination with current or previous reported use of eyeglasses for myopia to complete the SREEQ-R, which consists of 20 specific items divided into two sections each with three response categories. The "without glasses" section relates to perceptions of uncorrected vision/not wearing glasses, and the "with glasses" relates to corrected vision/wearing glasses. Rasch analysis was used to explore the psychometric performance (content, construct validity, and reliability) of the questionnaire items and scale using Winsteps software (Winsteps.com. Portland, OR). RESULTS: A total of 125 eligible children with a mean ± standard deviation age of 12.7 ± 2.9 years completed the SREEQ-R. All items fit the Rasch model and were retained, and the scale was found to be unidimensional. All children and item infit and outfit mean square statistics fell within the recommended fit criteria. As per the Rasch analysis, the person reliability coefficients were 0.84 and 0.91, whereas item reliabilities were 0.99 and 0.80 for the without glasses and with glasses sections, respectively. The internal consistency for the SREEQ-R was good; Cronbach α values were 0.84 for without glasses and 0.91 for with glasses. CONCLUSIONS: The SREEQ-R had satisfactory validity and reliability evidence. Construct validity of the scale was supported to measure the impact of uncorrected and corrected refractive error on vision-related quality of life in myopic school-aged children in the United Kingdom. The SREEQ-R could be used in future studies to evaluate vision-related quality of life in children with myopia.

ABSTRACT

Displaced persons are exposed to trauma and experience posttraumatic stress symptoms (PTS). Many displaced Muslims come from communities that rely on religious practices to cope with traumatic experiences, and religious coping has been identified as predictive of posttraumatic growth (PTG). Discrimination may contribute to increased PTS and promote in-group identification. In this study, we hypothesized that perceived discrimination would enhance the relationship between religious coping and PTG. Results indicated that religious coping predicted PTG, but the overall interaction with discrimination was not significant. However, probing moderating effects at discrete levels of discrimination yielded enhanced relationship between religious coping and PTG at its mean and above until reaching the highest values of discrimination. For individuals who experience moderate to high levels of discrimination, religious coping increased PTG. These findings highlight the essential role of religious coping in promoting growth for many Muslims exposed to forced migration and elevated levels of discrimination.

ABSTRACT

Refugees, asylum seekers, and internally displaced persons differ in their experiences, potentially affecting posttraumatic outcomes such as posttraumatic stress disorder (PTSD) symptoms, posttraumatic cognitions, and posttraumatic growth (PTG), as well as psychosocial outcomes such as social connection, discrimination, and well-being. We explored these differences in a sample of N = 112 Muslim displaced persons. Results from planned contrasts indicated that refugees reported more PTSD symptoms (t[46.63] = 3.04, p = 0.004, d = 0.77) and more PTG (t[94] = 2.71, p = 0.008, d = 0.61) than asylum seekers. Higher posttraumatic cognitions predicted less social connections across displacement immigration category. The strength of this relationship was more pronounced for asylum seekers than refugees (b = -0.43, p = 0.014). Refugees may focus more on direct threats from others, resulting in more PTSD symptoms, whereas asylum seekers' uncertainty may pose a greater threat, exacerbating posttraumatic beliefs that drive social disconnection.

ABSTRACT

OBJECTIVE: This study examines whether imaginal exposure leads to symptom exacerbation, systematically comparing individuals who received prolonged exposure (PE) to those who received pharmacotherapy. The study also examined whether common clinical features increase the likelihood of symptom exacerbation. METHOD: In 151 men and women with PTSD, we examined rates of reliable exacerbation of PTSD and depression symptoms after initiation of imaginal exposure and compared it to those receiving sertraline. We also examined relationships between exacerbation, treatment outcome, dropout, imaginal distress, and specific clinical features, including co-occurring MDD, multiple co-occurring disorders, childhood sexual abuse as target trauma, and a history of childhood physical or sexual abuse. RESULTS: Symptom exacerbation was not more common in PE compared to sertraline, not associated with higher dropout, or predictive of worse outcome. Those with co-occurring depression or multiple disorders, a target trauma of child sexual abuse, or a history of child abuse reported functionally equivalent peak distress at onset of imaginal as those without these characteristics. These factors did not lead to more exacerbation or worse adherence. CONCLUSION: Exacerbation was not specific to PE and patients with and without symptom worsening showed comparable treatment gains, suggesting symptom exacerbation may reflect a common clinical process.

ABSTRACT

The COVID-19 global pandemic is in many ways unchartered mental health territory, but history would suggest that long-term resilience will be the most common outcome, even for those most directly impacted by the outbreak. We address 4 common myths about resilience and discuss ways to systematically build individual and community resiliency. Actively cultivating social support, adaptive meaning, and direct prosocial behaviors to reach the most vulnerable can have powerful resilience promoting effects.

ABSTRACT

Women are disproportionately affected by posttraumatic stress disorder (PTSD), and gonadal hormones are implicated in fear learning processes associated with PTSD. In rodents, lower estradiol, particularly during metestrus when progesterone is also low, is associated with impaired extinction. Based on theories that extinction deficits underlie PTSD, individuals with lower estradiol and progesterone may exhibit fear learning deficits and higher PTSD symptomatology. A systematic review was conducted in PsycInfo, PubMed, and Medline databases for studies examining estradiol, progesterone, or menstrual phase in relation to fear learning or PTSD symptoms. Twenty-three studies are organized into fear learning (k = 17) and PTSD symptom (k = 12) studies. Across fear learning studies, higher estradiol was consistently associated with enhanced fear extinction recall and inconsistently and weakly associated with better extinction learning and fear acquisition, respectively. Extending to PTSD symptoms, the association with hormonal status was reversed, such that luteal phase, associated with higher estradiol and progesterone, was generally associated with higher re-experiencing symptoms. Overall, human fear learning studies were consistent with rodent studies. Despite strong experimental links between fear learning processes and PTSD, the clinical translation was inconsistent and may reflect varying methods, imprecise measurement, and greater complexity of hormonal effects on symptomatology.

ABSTRACT

OBJECTIVE: Chronic pain is a disabling illness, often comorbid with depression. We performed a randomized controlled pilot study on mindfulness-based cognitive therapy (MBCT) targeting depression in a chronic pain population. METHOD: Participants with chronic pain lasting ≥ 3 months; DSM-IV major depressive disorder (MDD), dysthymic disorder, or depressive disorder not otherwise specified; and a 16-item Quick Inventory of Depressive Symptomatology-Clinician Rated (QIDS-C16) score ≥ 6 were randomly assigned to MBCT (n = 26) or waitlist (n = 14). We adapted the original MBCT intervention for depression relapse prevention by modifying the psychoeducation and cognitive-behavioral therapy elements to an actively depressed chronic pain population. We analyzed an intent-to-treat (ITT) and a per-protocol sample; the per-protocol sample included participants in the MBCT group who completed at least 4 of 8 sessions. Changes in scores on the QIDS-C16 and 17-item Hamilton Depression Rating Sale (HDRS17) were the primary outcome measures. Pain, quality of life, and anxiety were secondary outcome measures. Data collection took place between January 2012 and July 2013. RESULTS: Nineteen participants (73%) completed the MBCT program. No significant adverse events were reported in either treatment group. ITT analysis (n = 40) revealed no significant differences. Repeated-measures analyses of variance for the per-protocol sample (n = 33) revealed a significant treatment × time interaction (F1,31 = 4.67, P = .039, η²p = 0.13) for QIDS-C16 score, driven by a significant decrease in the MBCT group (t18 = 5.15, P < .001, d = >1.6), but not in the control group (t13 = 2.01, P = .066). The HDRS17 scores did not differ significantly between groups. The study ended before the projected sample size was obtained, which might have prevented effect detection in some outcome measures. CONCLUSIONS: MBCT shows potential as a treatment for depression in individuals with chronic pain, but larger controlled trials are needed. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01473615.

ABSTRACT

Purpose: Breast cancer affects both genders, but is understudied in men. Although still rare, male breast cancer (MBC) is being diagnosed more frequently. Treatments are wholly informed by clinical studies conducted in women, based on assumptions that underlying biology is similar.Experimental Design: A transcriptomic investigation of male and female breast cancer was performed, confirming transcriptomic data in silico Biomarkers were immunohistochemically assessed in 697 MBCs (n = 477, training; n = 220, validation set) and quantified in pre- and posttreatment samples from an MBC patient receiving everolimus and PI3K/mTOR inhibitor.Results: Gender-specific gene expression patterns were identified. eIF transcripts were upregulated in MBC. eIF4E and eIF5 were negatively prognostic for overall survival alone (log-rank P = 0.013; HR = 1.77, 1.12-2.8 and P = 0.035; HR = 1.68, 1.03-2.74, respectively), or when coexpressed (P = 0.01; HR = 2.66, 1.26-5.63), confirmed in the validation set. This remained upon multivariate Cox regression analysis [eIF4E P = 0.016; HR = 2.38 (1.18-4.8), eIF5 P = 0.022; HR = 2.55 (1.14-5.7); coexpression P = 0.001; HR = 7.04 (2.22-22.26)]. Marked reduction in eIF4E and eIF5 expression was seen post BEZ235/everolimus, with extended survival.Conclusions: Translational initiation pathway inhibition could be of clinical utility in MBC patients overexpressing eIF4E and eIF5. With mTOR inhibitors that target this pathway now in the clinic, these biomarkers may represent new targets for therapeutic intervention, although further independent validation is required.

ABSTRACT

The aim of this work is to investigate the impact of placebo response rates on the relative risk of response to drug versus placebo in randomized, double-blind, placebo-controlled clinical trials of pharmacological therapy in Bipolar Depression (BPD). Medline/PubMed publication databases were searched for randomized, double-blind, placebo-controlled trials of oral drugs used as monotherapy for the treatment of BPD. The search was limited to articles published between January 1980 and September 2015. Data extracted from 12 manuscripts and one poster with yet unpublished results, representing a total of 17 clinical trials were pooled (n = 6578). Pooled response rates for drug and placebo were 55.1% and 39.2%, corresponding to a risk ratio (RR) for responding to active treatment versus placebo of 1.29 (p < 0.001). Clinical response was defined as a 50% or greater reduction in depression scores, baseline to endpoint. A higher placebo response rate correlated with a significantly lower RR of responding to pharmacotherapy versus placebo (p = 0.002). The pooled drug and placebo response rates for studies with a placebo response rate ≤ 30% were 50.5% versus 26.6%, while corresponding values from studies with a placebo response rate >30 were 55.0% versus 41.6%. These results suggest that the relative efficacy of the active drug compared to placebo in clinical trials for BPD is highly heterogeneous across studies with different placebo response rates, with a worse performance in showing a superiority of the drug versus placebo for studies with placebo response rates >30%. It is important to maintain placebo response rates below this critical threshold, since this is one of the most challenging obstacles for new treatment development in BPD.

ABSTRACT

Objective. We sought to demonstrate that maca root may be an effective treatment for antidepressant-induced sexual dysfunction (AISD) in women. Method. We conducted a 12-week, double-blind, placebo-controlled trial of maca root (3.0 g/day) in 45 female outpatients (mean age of 41.5 ± 12.5 years) with SSRI/SNRI-induced sexual dysfunction whose depression remitted. Endpoints were improvement in sexual functioning as per the Arizona Sexual Experience Scale (ASEX) and the Massachusetts General Hospital Sexual Function Questionnaire (MGH-SFQ). Results. 45 of 57 consented females were randomized, and 42 (30 premenopausal and 12 postmenopausal women) were eligible for a modified intent-to-treat analysis based on having had at least one postmedication visit. Remission rates by the end of treatment were higher for the maca than the placebo group, based on attainment of an ASEX total score ≤ 10 (9.5% for maca versus 4.8% for placebo), attaining an MGH-SFQ score ≤ 12 (30.0% for maca versus 20.0% for placebo) and reaching an MGH-SFQ score ≤ 8 (9.5% for maca versus 5.0% for placebo). Higher remission rates for the maca versus placebo group were associated with postmenopausal status. Maca was well tolerated. Conclusion. Maca root may alleviate SSRI-induced sexual dysfunction in postmenopausal women. This trial is registered with NCT00568126.

ABSTRACT

The aim of this work is to investigate placebo response rates in placebo-controlled randomized clinical trials (RCTs) of pharmacological therapy in bipolar depression (BPD) and to identify predictors of placebo response and clinical trial outcome in BPD. Medline/PubMed publication databases were searched for RCTs of oral drugs used as monotherapy for the treatment of BPD, published between January 1980 and September 2013. Data extracted from 12 manuscripts and one poster, representing a total of 17 clinical trials, were pooled. Pooled response rates for drug and placebo were 55.1 and 39.2%, corresponding to a risk ratio for responding to active treatment versus placebo of 1.29 (P<0.001). The probability of receiving placebo and trial duration correlated with the response rate to placebo. A meta-regression showed that trial duration and baseline severity correlated with the risk ratio of responding to drug versus placebo. There was a trend toward statistical significance for a greater probability of receiving placebo to predict greater drug-placebo 'separation'. In conclusion, several modifiable factors, specifically the probability of receiving placebo, baseline illness severity, and trial duration, correlate with placebo response rates and/or clinical trial outcome in RCTs of pharmacotherapy for BPD, and should be taken into account when designing studies for BPD.

ABSTRACT

Current measures for major depressive disorder focus primarily on the assessment of depressive symptoms, while often omitting other common features. However, the presence of comorbid features in the anxiety spectrum influences outcome and may effect treatment. More comprehensive measures of depression are needed that include the assessment of symptoms in the anxiety-depression spectrum. This study examines the reliability and validity of the Symptoms of Depression Questionnaire (SDQ), which assesses irritability, anger attacks, and anxiety symptoms together with the commonly considered symptoms of depression. Analysis of the factor structure of the SDQ identified 5 subscales, including one in the anxiety-depression spectrum, with adequate internal consistency and concurrent validity. The SDQ may be a valuable new tool to better characterize depression and identify and administer more targeted interventions.

ABSTRACT

To examine whether presentation of autism spectrum disorder (ASD) and associated patterns of psychiatric comorbidity and dysfunction vary by referral source. ASD youth referred to a specialized ambulatory program for ASD (N = 143) were compared to ASD youth referred to a general child psychiatry clinic (N = 217). More ASD clinic youth met criteria for a more robust form of ASD (autistic disorder); more youth referred to the psychiatry clinic met criteria for broader spectrum ASD (pervasive developmental disorder not otherwise specified). General psychiatry clinic youth with ASD suffered from a greater burden of psychopathologies and higher levels of dysfunction. The presentation of ASD in psychiatrically referred youth differs between general and ASD-specialized clinics, though both referral populations have high levels of comorbidity and dysfunction.

ABSTRACT

OBJECTIVE: To examine the comparative antidepressant efficacy of S-adenosyl-L-methionine (SAMe) and escitalopram in a placebo-controlled, randomized, double-blind clinical trial. METHOD: One hundred eighty-nine outpatients (49.7% female, mean [SD] age = 45 [15] years) with DSM-IV-diagnosed major depressive disorder (MDD) were recruited from April 13, 2005, to December 22, 2009, at the Massachusetts General Hospital and at Butler Hospital. Patients were randomized for 12 weeks to SAMe 1,600-3,200 mg/d, escitalopram 10-20 mg/d, or placebo. Doses were escalated at 6 weeks in the event of nonresponse. The main outcome measure was the 17-item Hamilton Depression Rating Scale (HDRS-17). Tolerability was assessed by the Systematic Assessment for Treatment of Emergent Events-Specific Inquiry (SAFTEE-SI). RESULTS: All 3 treatment arms demonstrated a significant improvement of about 5-6 points in HDRS-17 scores (P < .001 for all), and no significant differences were observed between the treatment arms (P > .05 for all). Response rates in the intent-to-treat sample were 36% for SAMe, 34% for escitalopram, and 30% for placebo. Remission rates were 28% for SAMe, 28% for escitalopram, and 17% for placebo. No comparisons between treatment groups attained significance (P > .05 for all). Tolerability was good, with gastrointestinal side effects (19% for stomach discomfort and 20% for diarrhea) as the most common in the SAMe arm. Significant differences were observed between treatment groups for dizziness, anorgasmia, diminished mental acuity, and hot flashes (P < .05 for all). CONCLUSIONS: The results fail to support an advantage over placebo for either the investigational treatment SAMe or the standard treatment escitalopram for MDD. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00101452.

ABSTRACT

Previous epidemiologic studies have revealed that East-Asian populations experience fewer depressive symptoms than American populations do. However, it is unclear whether this difference applies to clinical patients with major depressive disorder (MDD). This present study included 1592 Korean and 3744 American outpatients who were 18 years of age or older and met the Diagnostic and Statistical Manual of Mental Disorders, 4th ed. criteria for single or recurrent episodes of nonpsychotic MDD, and evaluated their symptoms of depression using the Hamilton Depression Rating Scale and the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form. Korean patients scored significantly lower for guilt and depressed mood items, and higher for hypochondriasis and suicidality items than American patients did, after adjusting for total Hamilton Depression Rating Scale scores. Conversely, no significant differences were found in quality and function of daily life between groups. Multivariate logistic regression analyses revealed that Korean patients experienced less frequent depressed mood and guilt, including verbal and nonverbal expression of depressed mood [adjusted odds ratio (AOR) = 0.14, 95% confidence interval (CI) 0.08-0.23] and feelings of punishment (AOR = 0.036, 95% CI 0.025-0.054) when compared with Americans after adjusting for age and sex. Conversely, Korean patients experienced more frequent suicidality and hypochondriasis, including suicidal ideas or gestures (AOR = 2.10, 95% CI 1.60-2.76) and self-absorption of hypochondriasis (AOR = 1.94, 95% CI 1.70-2.20). In conclusion, decreased expression of depressed mood and guilt may cause underdiagnosis of MDD in Korean patients. Early diagnosis of and intervention for depression and suicide may be delayed because of this specific cross-cultural difference in depression symptoms.

ABSTRACT

Hormonal stress response is associated with the pathogenesis of disease, including cancer. The role of the stress hormone CRH (corticotropin-releasing hormone) in breast cancer is complex, and its abundance and biological activity may be modulated by estrogen. In the estrogen receptor-positive (ER+) malignant mammary epithelial cell line MCF7, CRH activated numerous kinases and downstream effectors, at least some of which were mediated by the CRH receptor type 1 (CRH-R1). CRH also increased the transcription of many genes that encode effectors, transcriptional targets, or regulators associated with estrogen signaling. Estrogen increased the abundance of the mRNA encoding CRH-R2 and an alternative splice variant encoding CRH-R1 in which exon 12 was deleted [CRH-R1(Δ12)]. Estrogen inhibited the expression SRSF6, which encodes serine/arginine-rich splicing factor 55 (SRp55). An increase in CRH-R1(Δ12), in response to either estrogen or SRp55 knockdown, dampened the cellular response to CRH and prevented its inhibitory effects on cell invasion. SRp55 knockdown also induced additional splicing events within exons 9 to 12 of CRH-R1, whereas overexpression of SRp55 prevented estrogen-induced generation of CRH-R1(Δ12). ER+ breast tumors had increased CRH-R2 and CRH-R1(Δ12) mRNA abundance, which was associated with decreased abundance of the mRNA encoding SRp55, compared with the amounts in ER- tumors, suggesting that estrogen contributes to the pathophysiology of ER+ breast cancer by altering CRH receptor diversity and disrupting CRH-mediated signaling.
