RESUMO

Postpartum depression (PPD) affects nearly 20% of postpartum women in Sub-Saharan Africa (SSA), where HIV prevalence is high. Depression is associated with worse HIV outcomes in non-pregnant adults and mental health disorders may worsen HIV outcomes for postpartum women and their infants. PPD is effectively treated with psychosocial or pharmacologic interventions; however, few studies have evaluated the acceptability of treatment modalities in SSA. We analyzed interviews with 23 postpartum women with HIV to assess the acceptability of two depression treatments provided in the context of a randomized trial. Most participants expressed acceptability of treatment randomization and study visit procedures. Participants shared perceptions of high treatment efficacy of their assigned intervention. They reported ongoing HIV and mental health stigma in their communities and emphasized the importance of social support from clinic staff. Our findings suggest a full-scale trial of PPD treatment will be acceptable among women with HIV in Zambia.

RESUMO

The hormonal changes of pregnancy and parturition can trigger robust changes in affective state, particularly among patients with a history of postpartum depression. However, more work is needed to elucidate the temporal dynamics of symptom emergence. The current study explored how quickly hormone-sensitive (HS+) individuals can be differentiated from hormone-insensitive (HS-) controls in the context of a tightly controlled experimental hormone manipulation, and which symptoms demonstrate the most rapid, consistent, and largest response during this protocol. Participants were female, non-pregnant, and euthymic, with a history of DSM-5 major depressive episode with peripartum onset (n = 15) or parous healthy controls with no psychiatric history (n = 15). Perinatal hormonal changes were simulated by inducing hypogonadism, adding back estradiol (E2) and progesterone (P4) to reach first-trimester levels for 8 weeks, and then subsequently withdrawing both hormones. Those reporting a 30% or greater increase during addback or withdrawal on select subscales of the Inventory of Depression and Anxiety Symptoms (IDAS) were identified as HS+. Participants provided daily ratings of symptoms throughout the study via the Daily Record of Severity of Problems. Results indicated that HS+ participants could be differentiated from HS- participants early in the hormone protocol, with many symptoms showing significantly greater change from baseline within the first week of addback. Notably, the most rapid symptom increases were observed for Anger/Irritability, Mood Swings, Overwhelm, Lethargy, Increased Appetite, Joint and Muscle Pain, and Breast Tenderness, reaching 50% of peak group contrast within the first week of hormone addback. The largest group effects were observed for Anger/Irritability, followed by Fatigue and Anxiety, and the most consistent group effects were observed for Anger/Irritability, Interpersonal Conflict, Overwhelm, and Hopelessness. Findings support the role of reproductive hormones in the onset of perinatal affective disorders. The rapid emergence of anger and irritability in HS+ participants suggests that these symptoms may be early indicators of perinatal hormone sensitivity.

RESUMO

OBJECTIVES: To examine: (1) the psychometric properties of two therapist competence measures-multiple choice questionnaire (MCQ) and standardized role-plays; (2) whether therapist competence differed between non-specialist (NSPs) and specialist (SPs) providers; and (3) the relations between therapist competence and patient outcomes among perinatal patients receiving brief psychotherapy. METHODS: This study is embedded within the SUMMIT Trial-a large, ongoing psychotherapy trial for perinatal women with depressive and anxiety symptoms. We assessed the: (1) psychometric properties of therapist competence measures using Cronbach's alpha and inter-class correlation; (2) differences in therapist competence scores between n = 23 NSPs and n = 22 SPs using a two-sample t-test; and (3) relations between therapist competence measures and perinatal patient outcomes through a linear regression model. RESULTS: Internal consistency for role-play was acceptable (α = 0.71), whereas MCQ was excellent (α = 0.97). Role-play showed good inter-rater reliability (ICC = 0.80) and scores were higher for SPs compared with NSPs (t(2,38) = -2.86, p = 0.0069) and associated with outcomes of anxiety (B = 1.52, SE = 0.60, p = 0.01) and depressive (B = 0.96, SE = 0.55, p = 0.08) symptom scores. CONCLUSIONS: Our study highlights the importance of demonstrating psychological treatment skills through standardized role-plays over knowledge-based competence to predict perinatal patient outcomes. Using well-defined evidence-based tools is critical for deploying NSPs to provide high-quality psychotherapy and increase accessibility to psychological treatments for perinatal populations worldwide.

RESUMO

BACKGROUND: The perimenopausal transition is accompanied by psychiatric symptoms in over 10% of women. Symptoms commonly include depressed mood and anhedonia and less commonly include psychosis. Psychiatric symptoms have been linked to the depletion and/or variability of circulating estradiol, and estradiol treatment reduces perimenopausal anhedonia and psychosis in some women. Estrogen fluctuations may disrupt function in the mesolimbic reward system in some women, leading to psychiatric symptoms like anhedonia or psychosis. The Perimenopausal Effects of Estradiol on Anhedonia and Psychosis Study (PEEPs) is a mechanistic clinical trial that aims to (1) identify relationships between perimenopausal-onset anhedonia and psychosis and neuromolecular markers of mesolimbic reward responses and (2) determine the extent to which estradiol treatment-induced changes in mesolimbic reward responses are associated with alleviation of perimenopausal onset anhedonia or psychosis. METHODS: This study will recruit 100 unmedicated women ages 44-55 in the late-stage perimenopausal transition, sampling across the range of mild-to-high anhedonia and absent-to-moderate psychosis symptoms. Patients will be randomized to receive either estradiol or placebo treatment for 3 weeks. Clinical outcome measures will include symptoms of anhedonia (measured with Snaith-Hamilton Pleasure Scale; SHAPS) and psychosis (measured with Brief Psychiatric Rating Scale; BPRS psychosis subscale) as well as neural markers of mesolimbic reward system functioning, including reward-related fMRI activation and PET-derived measure of striatal dopamine binding. Pre-treatment associations between (1) SHAPS/BPRS scores and (2) reward-related striatal dopamine binding/BOLD activation will be examined. Furthermore, longitudinal mixed models will be used to estimate (1) symptom and neuromolecular trajectories as a function of estradiol vs. placebo treatment and (2) how changes in reward-related striatal dopamine binding and BOLD activation predict variability in symptom trajectories in response to estradiol treatment. DISCUSSION: This clinical trial will be the first to characterize neural and molecular mechanisms by which estradiol treatment ameliorates anhedonia and psychosis symptoms during the perimenopausal transition, thus laying the groundwork for future biomarker research to predict susceptibility and prognosis and develop targeted treatments for perimenopausal psychiatric symptoms. Furthermore, in alignment with the National Institute for Mental Health Research Domain Criteria initiative, this trial will improve our understanding of a range of disorders characterized by anhedonia, psychosis, and reward system dysfunction.

RESUMO

The COVID-19 pandemic has presented many stressors for parents. This study was conducted to examine treatment preferences and barriers to care amidst COVID-19. Parents (N â€‹= â€‹95) completed self-report measures. Education was provided on interventions (e.g., individual therapy, medication), and acceptability assessed. Elevated stress and distress were observed. Parents indicated interest in services for parenting concerns, stress, anxiety, and depression. Individual therapy and telehealth were highly acceptable, while medication and group therapy were less accepted. Findings highlight the need for specific supports among parents amidst the pandemic. Factors that influence treatment preference warrant further attention. Implications for healthcare service delivery are discussed.

RESUMO

OBJECTIVE: There is a critical need to better understand psychological treatments from a culturally sensitive lens. Using a process-oriented model, we examined treatment satisfaction among perinatal patients who received behavioral activation (BA) within a large psychotherapy trial for perinatal depression and anxiety, and explored how to optimize culturally sensitive delivery through a multistakeholder perspective. METHOD: In this mixed methods study, we estimated treatment satisfaction through mean client satisfaction scores (Client Satisfaction Questionnaire [CSQ]-8) among perinatal participants (N = 417) using one-way analysis of variance. We also conducted semistructured interviews with 20 ethnically diverse perinatal participants, 19 treatment providers, and five clinical leads. We employed content analysis to identify barriers, facilitators, and strategies for delivering culturally sensitive treatment. RESULTS: CSQ-8 scores were similar across ethnic groups, F(7, 409) = 0.70, p = .67. Most participant interviewees reported that topics of race, ethnicity, and culture were raised during treatment sessions and that providers were able to address these topics in a culturally sensitive way. Despite this, almost all providers and clinical leads reported insufficient training to deliver culturally sensitive psychotherapy. The most-endorsed challenge for participants and providers was apprehension to bring up issues of race and ethnicity during treatment. Key facilitators included provider style, previous training, ongoing training resources, and supervision. CONCLUSION: BA offers one psychotherapeutic model that uses an idiosyncratic and process-oriented approach that fosters intersectional humility and benefits from cultural humility, comfort, and opportunities. We identify key recommendations to inform culturally sensitive, evidence-based psychological treatments that include explicitly acknowledging and eliciting topics of race, ethnicity, and culture during sessions and supervision and ongoing training and supervision.

RESUMO

INTRODUCTION: Postpartum depression (PPD) is a prevalent and debilitating disease that may affect medication adherence and thus maternal health and vertical transmission among women with HIV. We assessed the feasibility of a trial of interpersonal psychotherapy (IPT) versus antidepressant medication (ADM) to treat PPD and/or anxiety among postpartum women with HIV in Lusaka, Zambia. METHODS: Between 29 October 2019 and 8 September 2020, we pre-screened women 6-8 weeks after delivery with the Edinburgh Postnatal Depression Scale (EPDS) and diagnosed PPD or anxiety with the Mini International Neuropsychiatric Interview. Consenting participants were randomized 1:1 to up to 11 sessions of IPT or daily self-administered sertraline and followed for 24 weeks. We assessed EPDS score, Clinical Global Impression-Severity of Illness (CGI-S) and medication side effects at each visit and measured maternal HIV viral load at baseline and final study visit. Retention, visit adherence, change in EPDS, CGI-S and log viral load were compared between groups with t-tests and Wilcoxon signed rank tests; we report mean differences, relative risks and 95% confidence intervals. A participant satisfaction survey assessed trial acceptability. RESULTS: 78/80 (98%) participants were retained at the final study visit. In the context of the COVID-19 pandemic, visit adherence was greater among women allocated to ADM (9.9 visits, SD 2.2) versus IPT (8.9 visits, SD 2.4; p = 0.06). EPDS scores decreased from baseline to final visit overall, though mean change was greater in the IPT group (-13.8 points, SD 4.7) compared to the ADM group (-11.4 points, SD 5.5; p = 0.04). Both groups showed similar changes in mean log viral load from baseline to final study visit (mean difference -0.43, 95% CI -0.32, 1.18; p = 0.48). In the IPT group, viral load decreased significantly from baseline (0.9 log copies/ml, SD 1.7) to final visit (0.2 log copies/ml, SD 0.9; p = 0.01). CONCLUSIONS: This pilot study demonstrates that a trial of two forms of PPD treatment is feasible and acceptable among women with HIV in Zambia. IPT and ADM both improved measures of depression severity; however, a full-scale trial is required to determine whether treatment of PPD and anxiety improves maternal-infant HIV outcomes.

RESUMO

OBJECTIVE: Acceptance and commitment therapy (ACT) has demonstrated effectiveness in addressing symptoms of anxiety and depression, frequently experienced by patients with systemic lupus erythematosus (SLE). The goal of this pilot study was to develop and assess the feasibility and acceptability of a novel web-based ACT skills training program tailored for patients with lupus: ACT for Lupus. The program served as a complementary approach to support the management of symptoms and stressors during the COVID-19 pandemic. METHODS: This study employed a single-group pretest-posttest design. Participants with a diagnosis of SLE were primarily recruited through an institutional healthcare system between November 25, 2020 and December 17, 2020 and through an online national lupus organization listserv. Participants were invited to attend two 1-hour webinars delivered over a 2-week period. Educational ACT-based content was tailored for patients with lupus and delivered by an experienced clinical psychologist specializing in ACT. Surveys assessed patient-reported outcomes of anxiety, depression, and quality of life and evaluated program feedback, usability, and satisfaction. RESULTS: A total of 83 participants submitted the baseline survey, with 21 participants designated as study completers. The program was well received by participants, who reported feasibility and acceptability of the intervention, as reflected by high usability ratings. Participants reported favorable experiences with the program. Feedback included suggestions to include additional lupus-tailored content, increase the range and scope of sessions and activities, and improve program flexibility and availability to avoid scheduling conflicts. CONCLUSION: This study provides preliminary evidence for an adapted, ACT-based virtual skills training program as a feasible and acceptable intervention to support the well-being of patients with lupus.

RESUMO

BACKGROUND: We examined the implementation of a brief, behavioural activation (BA) model, via telemedicine, for perinatal populations during a confluence of significant global events in 2020. We conducted a rigorous qualitative study to identify relevant barriers and facilitators from the perspectives of both perinatal participants and treatment providers. We also present two case studies where BA was used and adapted to provide patient-centered care. METHODS: Within the ongoing SUMMIT non-inferiority randomized controlled trial in Canada and USA, we interviewed a random selection of perinatal participants (n = 23) and all treatment providers (n = 28). A content analysis framework was developed to identify relevant barriers and facilitators and frequencies were calculated for each emergent theme within and across respondent groups. RESULTS: Key facilitators reported by participants receiving BA were that BA helped with support and social connection (73.9%), creative problem solving (26.1%) and attending to pandemic-related symptoms (21.7%). Key facilitators endorsed by providers delivering BA were the use of telemedicine (35.7%) and loosening of government restrictions (21.4%). Both participant groups reported similar barriers to BA during the pandemic such as a lack of privacy and limited activities due to pandemic restrictions. However, providers were more likely to endorse pandemic-related life stressors as a barrier to treatment delivery compared to participants (64.3% vs. 34.8%). Both participant groups experienced explicit discussion of race and the racial justice movements during sessions as beneficial and reported harms of not doing so to the therapeutic alliance. CONCLUSIONS: BA offers a person-centered model to facilitate social connection through creative problem-solving for women with perinatal depressive and anxiety symptoms within the context of the COVID-19 pandemic. Explicit discussion of race and racial injustice during sessions is an important and helpful aspect in psychological treatments.

RESUMO

BACKGROUND: Perinatal distress (PD) is a term used to describe mood and anxiety disorders experienced during pregnancy or in the postpartum period. In acute cases of PD, inpatient hospitalization may be indicated. Although hospitalization tends to result in improved immediate safety outcomes, many patients are discharged when they are still experiencing acute symptomology. Interpersonal and environmental factors, particularly those that exist within intimate relationships, can significantly help or hinder patient progress. Partners are also affected by the patient's symptoms and often lacks the skills or knowledge to offer support. METHODS: The aim of the present investigation is to address PD through a dyadic lens by integrating partners into treatment. In this feasibility study, 20 partners of women hospitalized for PD were recruited to participate in an individually delivered, 90-minute intervention designed to improve partner understanding and support behaviors. RESULTS: Qualitative feedback from partners suggests that the intervention was acceptable and the high recruitment rates demonstrate strong feasibility. Additionally, partners reported significant gains in the context of their support self-efficacy for assisting patients to cope with distress. Patients reported that they were significantly more satisfied with the support that their partners were providing. LIMITATIONS: This was a feasibility study and as such, there was no control group, thereby limiting causal inferences about the intervention. CONCLUSIONS: These findings suggest that this intervention may serve to enhance the recovery of women hospitalized for PD by empowering partners through offering psychoeducation and skills for offering support.

RESUMO

OBJECTIVE: Eating disorder symptoms change in a predictable pattern over the menstrual cycle such that changes in symptoms are triggered by changes in the ovarian hormones estradiol (E2) and progesterone (P4). To date, work in this area has focused exclusively on young adult women. The objective of this pilot study was to examine the effect of E2 and P4 on eating disorder symptom change in midlife women during early perimenopause. METHOD: Participants included women aged 42-52 in early perimenopause (n=8). In-home self-assessments were completed for one menstrual cycle or 40-days, whichever occurred first. In-home self-assessments included collecting saliva samples each morning for E2 and P4 assays and completing online study questionnaires at the end of each day. Multilevel regression models examined the associations of E2 and P4 with daily symptoms of binge eating and body dissatisfaction. RESULTS: E2 was positively associated with binge eating when P4 was high, but not when P4 was low. E2 was inversely associated with body dissatisfaction when P4 was low, but positively associated with body dissatisfaction when P4 was high. However, the simple slopes for the effect of E2 at both high and low P4 were not significant for body dissatisfaction. CONCLUSIONS: Despite the pilot nature of this study, results are broadly consistent with the young adult literature indicating that P4 levels shape the impact of E2 on eating disorder symptoms. Larger studies with the inclusion of key moderators to account for individual heterogeneity are needed to confirm and extend these findings.

RESUMO

Between 10% and 20% of women will experience depression in the perinatal period, which begins during pregnancy and extends into the first year after delivery. Perinatal depression (PD) is associated with significant emotional and social impairments that impact women, their children, and their partners. Although the majority of women with PD do not seek treatment, a considerable proportion of those who engage in treatment do not achieve remission. The couples and depression literature suggests that interpersonal processes are central in the development and maintenance of depressive disorders and thus, as researchers seek safe and effective treatments for perinatal populations, there may be therapeutic benefit in examining the role that partners play in women's recovery. The primary goal of this practice review is to highlight the utility of including partners in treatment for maternal PD and propose a model for practitioners to guide their work with couples within this domain. Specifically, this model involves three key components of treatment: psychoeducation, communication training, and behavioral activation. Each component addresses distinct risk factors for women and couples in the perinatal period in hopes of offering guidance to practitioners for how to address PD symptomology through a dyadic lens.

RESUMO

RATIONALE: Anxiety during pregnancy has been linked to adverse maternal health outcomes, including postpartum depression (PPD). However, there has been limited study of biological mechanisms underlying behavioral predictors of PPD during pregnancy. OBJECTIVES: Considering the shared etiology of chronic stress amongst antenatal behavioral predictors, the primary goal of this pilot study was to examine associations among stress-related physiological factors (including GABA-ergic neurosteroids) and stress-related behavioral indices of anxiety during pregnancy. METHODS: Fourteen nulliparous women in their second trimester of a singleton pregnancy underwent speech and mental arithmetic stress, following a 2-week subjective and objective recording of sleep-wake behavior. RESULTS: Lower cortisol, progesterone, and a combined measure of ALLO + pregnanolone throughout the entire stressor protocol (area under the curve, AUC) were associated with greater negative emotional responses to stress, and lower cortisol AUC was associated with worse sleep quality. Lower adrenocorticotropic hormone was associated with greater anxious and depressive symptoms. Stress produced paradoxical reductions in cortisol, progesterone, and a combined measure of allopregnanolone + pregnanolone, while tetrahydrodeoxycorticosterone levels were elevated. CONCLUSIONS: These data suggest that cortisol, progesterone, and ALLO + pregnanolone levels in the second trimester of pregnancy are inversely related to negative emotional symptoms, and the negative impact of acute stress challenge appears to exert its effects by reducing these steroids to further promote negative emotional responses.

RESUMO

OBJECTIVE: Individual differences in sensitivity to cyclical changes in ovarian steroids estradiol (E2) and progesterone (P4) have been implicated in the pathophysiology of menstrually related mood disorder (MRMD). However, no prospective studies have investigated psychosocial risk factors for sensitivity to hormone effects on mood in MRMD. Using a repeated measures approach and multilevel models, we tested the hypothesis that a history of abuse provides a context in which within-person elevations of E2 and P4 prospectively predict daily symptoms. METHOD: 66 women with prospectively-confirmed MRMD recruited for a trial of oral contraceptives provided 1 month of baseline hormone and mood data prior to randomization. Lifetime physical and sexual abuse experiences were assessed. Across one cycle, women completed daily measures of symptoms and provided blood samples on 5 days across the menstrual cycle. Current E2 and P4 were centered within person (CWP) such that higher values represented cyclical elevations in hormones. RESULTS: Rates of physical (27%) and sexual (29%) abuse were high, consistent with previous work documenting a link between trauma and MRMD. In women with a history of physical abuse, cyclical increases in P4 predicted greater mood and interpersonal symptoms on the three days following that sample. In women with a history of sexual abuse, cyclical increases in E2 predicted greater anxiety symptoms on the three days following that sample. CONCLUSIONS: Results inform further inquiry into the role of severe life stressors and stress response systems in MRMD. We discuss areas for future research on the psychosocial and physiological pathways through which abuse may influence the link between hormones and symptoms.

RESUMO

Changes in neurosteroid levels during the luteal phase of the menstrual cycle may precipitate affective symptoms. To test this hypothesis, we stabilized neurosteroid levels by administering the 5α-reductase inhibitor dutasteride to block conversion of progesterone to its neurosteroid metabolite allopregnanolone in women with premenstrual dysphoric disorder (PMDD) and in asymptomatic control women. Sixteen women with prospectively confirmed PMDD and 16 control women participated in one of two separate randomized, double-blind, placebo-controlled, cross-over trials, each lasting three menstrual cycles. After one menstrual cycle of single-blind placebo, participants were randomized to receive, for the next two menstrual cycles, either double-blind placebo or dutasteride (low-dose 0.5 mg/day in the first eight PMDD and eight control women or high-dose 2.5 mg/day in the second group of women). All women completed the daily rating form (DRF) and were evaluated in clinic during the follicular and luteal phases of each menstrual cycle. Main outcome measures were the DRF symptoms of irritability, sadness, and anxiety. Analyses were performed with SAS PROC MIXED. In the low-dose group, no significant effect of dutasteride on PMDD symptoms was observed compared with placebo (ie, symptom cyclicity maintained), and plasma allopregnanolone levels increased in women with PMDD from follicular to the luteal phases, suggesting the absence of effect of the low-dose dutasteride on 5α-reductase. In contrast, the high-dose group experienced a statistically significant reduction in several core PMDD symptoms (ie, irritability, sadness, anxiety, food cravings, and bloating) on dutasteride compared with placebo. Dutasteride had no effect on mood in controls. Stabilization of allopregnanolone levels from the follicular to the luteal phase of the menstrual cycle by blocking the conversion of progesterone to its 5α-reduced neurosteroid metabolite mitigates symptoms in PMDD. These data provide preliminary support for the pathophysiologic relevance of neurosteroids in this condition.
