RESUMO
The purpose is to investigate the natural course and long-term prognosis of postpartum depression (PPD). In this retrospective longitudinal cohort study, mothers diagnosed as either suffering from PPD or without PPD were reassessed 5-8 years thereafter by a semi-structured interview and their charts were reviewed for past psychiatric illness prior to the index (initial) episode and for new-onset episodes in the following years. Present psychiatric state was also evaluated by interview and questionnaires. Sixty-five mothers with and 35 without past PPD underwent the full assessment. A total of 66.2% of mothers with past PPD had any axis I psychopathology before their index PPD episode, compared with only 8.6% in the non-PPD group (p < 0.001, φ = .55). Furthermore, 37.2% of the females who had a history of PPD and experienced subsequent childbirths during the follow-up years, developed at least one new episode of PPD. Throughout the 5 years subsequent to the index PPD episode, 42.5% of the PPD group compared with only 3.7% for the non-PPD group developed a new episode of depression (p < 0.001). Lastly, reported psychopathology was higher and functional level was significantly worse in the PPD group at the time of reassessment. Females who develop an episode of PPD show a high degree of subsequent psychopathology and unfavorable prognosis. Clinicians treating females for PPD should consider a longer treatment continuation phase in an effort to prevent further psychopathology and a closer follow-up program.

AIM: Childhood sexual abuse (CSA) among women is an alarmingly prevalent traumatic experience that often leads to debilitating and treatment-refractory posttraumatic stress disorder (PTSD), raising the need for novel adjunctive therapies. Neuroimaging investigations systematically report that amygdala hyperactivity is the most consistent and reliable neural abnormality in PTSD and following childhood abuse, raising the potential of implementing volitional neural modulation using neurofeedback (NF) aimed at down-regulating amygdala activity. This study aimed to reliably probe limbic activity but overcome the limited applicability of functional magnetic resonance imaging (fMRI) NF by using a scalable electroencephalogram NF probe of amygdala-related activity, termed amygdala electrical-finger-print (amyg-EFP) in a randomized controlled trial. METHOD: Fifty-five women with CSA-PTSD who were in ongoing intensive trauma-focused psychotherapy for a minimum of 1 year but still met Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) PTSD criteria were randomized to either 10 add-on sessions of amyg-EFP-NF training (test group) or continuing psychotherapy (control group). Participants were blindly assessed for PTSD symptoms before and after the NF training period, followed by self-reported clinical follow-up at 1, 3, and 6 months, as well as one session of amygdala real-time fMRI-NF before and after NF training period. RESULTS: Participants in the test group compared with the control group demonstrated a marginally significant immediate reduction in PTSD symptoms, which progressively improved during the follow-up period. In addition, successful neuromodulation during NF training was demonstrated. CONCLUSION: This feasibility study for patients with treatment-resistant CSA-PTSD indicates that amyg-EFP-NF is a viable and efficient intervention.

BACKGROUND: Contemporary views of emotion dysregulation in post-traumatic stress disorder (PTSD) highlight reduced ability to flexibly select regulatory strategies according to differing situational demands. However, empirical evidence of reduced regulatory selection flexibility in PTSD is lacking. Multiple studies show that healthy individuals demonstrate regulatory selection flexibility manifested in selecting attentional disengagement regulatory strategies (e.g. distraction) in high-intensity emotional contexts and selecting engagement meaning change strategies (e.g. reappraisal) in low-intensity contexts. Accordingly, we hypothesized that PTSD populations will show reduced regulatory selection flexibility manifested in diminished increase in distraction (over reappraisal) preference as intensity increases from low to high intensity. METHODS: Study 1 compared student participants with high (N = 22) post-traumatic symptoms (PTS, meeting the clinical cutoff for PTSD) and participants with low (N = 22) post-traumatic symptoms. Study 2 compared PTSD diagnosed women (N = 31) due to childhood sexual abuse and matched non-clinical women (N = 31). In both studies, participants completed a well-established regulatory selection flexibility performance-based paradigm that involves selecting between distraction and reappraisal to regulate negative emotional words of low and high intensity. RESULTS: Beyond demonstrating adequate psychometric properties, Study 1 confirmed that relative to the low PTS group, the high PTS group presented reduced regulatory selection flexibility (p = 0.01, Ųâ= 0.14). Study 2 critically extended findings of Study 1, in showing similar reduced regulatory selection flexibility in a diagnosed PTSD population, relative to a non-clinical population (p = 0.002, Ųâ= 0.114). CONCLUSIONS: Two studies provide converging evidence for reduced emotion regulatory selection flexibility in two PTSD populations.

AIM: To assess the efficacy of a novel neurofeedback (NF) method, targeting limbic activity, to treat emotional dysregulation related to premenstrual dysphoric disorder (PMDD). METHODS: We applied a NF probe targeting limbic activity using a functional magnetic resonance imaging-inspired electroencephalogram model (termed Amyg-EFP-NF) in a double-blind randomized controlled trial. A frontal alpha asymmetry probe (AAS-NF), served as active control. Twenty-seven participants diagnosed with PMDD (mean age = 33.57 years, SD = 5.67) were randomly assigned to Amyg-EFP-NF or AAS-NF interventions with a 2:1 ratio, respectively. The treatment protocol consisted of 11 NF sessions through three menstrual cycles, and a follow-up assessment 3 months thereafter. The primary outcome measure was improvement in the Revised Observer Version of the Premenstrual Tension Syndrome Rating Scale (PMTS-OR). RESULTS: A significant group by time effect was observed for the core symptom subscale of the PMTS-OR, with significant improvement observed at follow-up for the Amyg-EFP group compared with the AAS group [F(1, 15)=4.968, P = 0.042]. This finding was specifically robust for reduction in anger [F(1, 15) = 22.254, P < 0.001]. A significant correlation was found between learning scores and overall improvement in core symptoms (r = 0.514, P = 0.042) suggesting an association between mechanism of change and clinical improvement. CONCLUSION: Our preliminary findings suggest that Amyg-EFP-NF may serve as an affordable and accessible non-invasive treatment option for emotional dysregulation in women suffering from PMDD. Our main limitations were the relatively small number of participants and the lack of a sham-NF placebo arm.

INTRODUCTION: Women are more likely to develop depression during the perinatal period than at any other time in their lives. Studies from recent years raise significant concerns regarding the potential of a depressive disorder in the pregnant mother to cause adverse obstetric results for the mother and the newborn. As antidepressants can penetrate the placenta to different degrees, concern has been raised regarding their teratogenic potential. In recent years various inconsistent and ambiguous reports specifying mild risks to the fetus and newborn from exposure to serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs) during pregnancy have been published. This paper provides a review of current medical knowledge regarding the pharmacological treatment with common antidepressants such as SSRIs and SNRIs in pregnant women. Based on this review we also present treatment and follow-up recommendations of the major published guidelines for the treatment of serotonin and norepinephrine reuptake inhibitors (SSRIs and SNRIs) during pregnancy for the medical care providers.

Gonadal steroids (GSs) have been repeatedly shown to play a central role in the onset of postpartum depression (PPD). The underlying mechanisms, however, are only partially understood. We investigated the relationship between cognitive processing of emotional information and naturally occurring hormonal fluctuations in women with and without previous PPD. Euthymic, parous women, with a history (hPPD, n=32) and without a history (nhPPD, n=43) of PPD, were assessed during late-follicular and late-luteal phases. Participants were administered cognitive tasks assessing attention (dot-probe; emotional Stroop), evaluation (self-referential encoding) and incidental recall, and self-report measures. Menstrual-phase-specific differences were found between late-follicular vs. late-luteal phases among hPPD only, with depression-associated patterns observed in the late-luteal phase on the self-referential encoding and incidental recall task and emotional Stroop task, but not on the dot-probe task. No main effect for menstrual phase was found on any of the tasks or questionnaires, apart from the brooding component of rumination. Women with hPPD demonstrate a differential bias in cognitive processing of emotional information that is menstrual phase dependent, and did not correspond to similar difference in mood symptoms. These biases may reflect sensitivity to gonadal steroid fluctuations that are associated with PPD.

BACKGROUND: Ketamine has been demonstrated to improve depressive symptoms.AimsEvaluation of efficacy, safety and feasibility of repeated oral ketamine for out-patients with treatment-resistant depression (TRD). METHOD: In a randomised, double-blind, placebo-controlled, proof-of-concept trial, 41 participants received either 1 mg/kg oral ketamine or placebo thrice weekly for 21 days (ClinicalTrials.gov Identifier: NCT02037503). Evaluation was performed at baseline, 40 and 240 min post administration and on days 3, 7, 14 and 21. The main outcome measure was change in Montgomery-Åsberg Depression Rating Scale (MADRS). RESULTS: Twenty-two participants were randomised to the ketamine group, and 19 to the control, with 82.5% (n = 33) completing the study. In the ketamine group, a decrease in depressive symptoms was evident at all time points, whereas in the control group a decrease was evident only 40 min post administration. The reduction in MADRS score on day 21 was 12.75 in the ketamine group versus 2.49 points with placebo (P < 0.001). Six participants in the ketamine group (27.3%) achieved remission compared with none of the controls (P < 0.05). The number needed to treat for remission was 3.7. Side-effects were mild and transient. CONCLUSIONS: Repeated oral ketamine produced rapid and persistent amelioration of depressive symptoms in out-patients with TRD, and was well tolerated. These results suggest that add-on oral ketamine may hold significant promise in the care of patients suffering from TRD in the community.Declaration of interestNone.

To explore the mood protective effect of prophylactic SSRI treatment on women undergoing IVF suffering from moderate affective and anxiety symptoms. In a randomized double blind, placebo-controlled, parallel design study, 41 women diagnosed with an Adjustment Disorder, who were undergoing IVF treatments, were randomized into two groups; a study group (n = 22) administered escitalopram 10 mg/day, and a control group (n = 19) administered placebo for a total of 8 weeks before and during the IVF treatment cycle. Patients were assessed at the onset of drug treatment and at embryo transfer. The main outcome measure was the difference in mean score severity rating of depression and anxiety symptoms on the CES-D and Zung questionnaires between groups at the time of embryo transfer. Secondary outcome measures included the MHI rating subscales addressing aspects of psychological distress and coping. At the day of embryo transfer (6 weeks of drug treatment), the CES-D average score for the treatment group was 6.40 (6.71) and 27.47 (4.29) on the Zung Self-Rating Anxiety Scale, while the placebo group scored an average of 15.83 (8.69) and 33.17 (6.95) receptively. These findings were significant (p = .004, p = .015 receptively) and were endorsed by the scoring on the MHI questionnaire subscales. Short-term treatment with SSRI may serve as a prophylactic treatment against the perpetuation and possible worsening of depressive and anxiety symptoms in women undergoing IVF treatments. Further studies concerning pharmacological interventions in larger samples and studies addressing screening for psychological stress indicators in this population are warranted.

BACKGROUND: Empathy refers to the cognitive and emotional reactions of an individual to the experiences of another. Women with premenstrual dysphoric disorder (PMDD) report severe social difficulties during the luteal phase of their menstrual cycle. AIMS: This clinical and functional magnetic resonance imaging study aimed to explore affective and cognitive empathy in women with PMDD, during the highly symptomatic luteal phase. METHOD: Overall, 32 women with PMDD and 20 healthy controls participated in the study. The neuroimaging data were collected using a highly empathy-engaging movie. First, we characterised the synchrony of neural responses within PMDD and healthy groups, using the inter-individual correlation approach. Next, using network cohesion analysis, we compared connectivity within and between brain networks associated with affective and cognitive empathy between groups, and assessed the association of these network patterns with empathic measures. RESULTS: A consistent, although complex, picture of empathy abnormalities was found. Patients with PMDD showed decreased neural synchrony in parietal and frontal key nodes of cognitive empathy processing (theory-of-mind network), but higher neural synchrony in the anterior insula and anterior cingulate cortex, a part of the salience network, implicated in affective empathy. Positive correlations between cognitive perspective-taking scores and neural synchrony were found within the theory-of-mind network. Interestingly, during highly emotional moments, the PMDD group showed increased functional connectivity within this network. CONCLUSIONS: Similar to major depression, individuals with PMDD show enhanced affective empathy and reduced cognitive empathy. These findings echo clinical observations reported when women with PMDD have a dysregulated emotional response to negative stimuli.
RESUMO
Treatment Rationale: Exposure to repeated sexual trauma, particularly during childhood, often leads to protracted mental health problems. Childhood adversity is specifically associated with complex posttraumatic stress disorder (PTSD) presentation, which is particularly tenacious and treatment refractory, and features severe emotion dysregulation. Augmentation approaches have been suggested to enhance treatment efficacy in PTSD thus integrating first-line psychotherapy with mechanistically informed self-neuromodulation procedures (i.e. neurofeedback) may pave the way to enhanced clinical outcomes. A central neural mechanism of PTSD and emotion dysregulation involves amygdala hyperactivity that can be volitionally regulated by neurofeedback. We outline a treatment rationale that includes a detailed justification for the potential of combining psychotherapy and NF and delineate mechanisms of change. We illustrate key processes of reciprocal interactions between neurofeedback engagement and therapeutic goals.Case Study: We describe a clinical case of a woman with complex PTSD due to early and repetitive childhood sexual abuse using adjunctive neurofeedback as an augmentation to an ongoing, stable, traditional treatment plan. The woman participated in (a) ten sessions of neurofeedback by the use of an fMRI-inspired EEG model of limbic related activity (Amygdala Electrical-Finger-Print; AmygEFP-NF), (b) traditional weekly individual psychotherapy, (c) skills group. Before and after NF training period patient was blindly assessed for PTSD symptoms, followed by a 1, 3- and 6-months self-report follow-up. We demonstrate mechanisms of change as well as the clinical effectiveness of adjunctive treatment as indicated by reduced PTSD symptoms and improved daily functioning within this single case.Conclusions: We outline an integrative neuropsychological framework for understanding the unique mechanisms of change conferring value to conjoining NF applications with trauma-focused psychotherapy in complex PTSD.
Self-neuromodulation procedures that regulates limbic-related activity in adjunction to therapy show clinical effectivity in complex PTSD.We present an integrative perspective of neurofeedback embedded in psychotherapy, illustrated by a single case report.A single case provides an illustration of the potential utility of multifaced treatment including psychotherapy with adjunctive neurofeedback.

The present study aimed to estimate posttraumatic stress symptoms (PTSS) and posttraumatic growth (PTG) among heart disease survivors and examine whether PTG moderates the association between PTSS and mental health. Data from 82 myocardial infarction and acute coronary artery bypass graft survivors (aged 46-82) was obtained at admission to a cardiac rehabilitation unit. Mental status was assessed by the PTSD Inventory, Posttraumatic Growth Inventory (PTGI), Mental Health Inventory and Health Related Quality of Life (HRQOL). 17.1 % of the participants suffered significantly from PTSS and most of the study sample (71.2 %) reported PTG. PTSS were positively associated with PTG and psychological distress and negatively with well-being and HRQOL. PTG moderated the association between PTSS and most mental health outcomes. We conclude that posttraumatic growth may attenuate the negative effect of posttraumatic stress symptoms on mental health.

OBJECTIVE: Social anxiety disorder is common and impairing. The efficacy of pharmacotherapy is moderate, highlighting the need for alternative therapies. This study compared the efficacy of gaze-contingent music reward therapy (GC-MRT), an eye-tracking-based attention bias modification treatment, with a selective serotonin reuptake inhibitor (SSRI) treatment or a waiting list control condition in reducing social anxiety disorder symptoms. Superior clinical effects of similar magnitude were expected for the active treatments relative to the control condition. METHODS: Participants were 105 treatment-seeking adults with social anxiety disorder, randomly allocated to 12 weeks of GC-MRT, SSRI, or waiting list control. Mean changes in clinician-rated and self-reported social anxiety symptoms from baseline to mid- and posttreatment assessments were compared between groups using generalized estimating equations. Changes in attentional dwell time on threat were also examined. RESULTS: Analysis indicated a significant differential reduction in symptoms between groups. Patients in the GC-MRT and SSRI groups had lower social anxiety scores at the mid- and posttreatment assessments compared with patients in the waiting list group. The efficacy of the active treatments did not differ. Only patients in the GC-MRT group showed reduction in dwell time on threat from baseline to posttreatment assessment. CONCLUSIONS: Eye-tracking-based attention bias modification is an acceptable and effective treatment option for social anxiety disorder.

The influence of psychological processes and psychiatric syndromes on the outcome of fertility treatments is not well understood. In this prospective study, we investigated the effect of baseline psychiatric diagnosis and situational psychiatric symptoms on several biological outcome factors of in vitro fertilization treatments (IVF). Women undergoing their first IVF treatment (n = 108) were interviewed before treatment for the presence of a lifetime DSM-IV-TR disorder. Questionnaires measuring state depression (Center for Epidemiologic Studies Depression scale), anxiety (State Trait Anxiety Inventory), and psychiatric symptomatology (Brief Symptom Inventory) were administered at ovulation induction. Outcome variables were number of retrieved and fertilized oocytes, chemical pregnancy, and a take home baby. Situational anxiety, depression, or other psychiatric symptoms had no effect on any of the outcome measures. Women diagnosed with mood or anxiety disorder prior to the onset of the IVF treatment showed a higher, though not statistically significant, pregnancy success rate compared to women without a diagnosis (57 % compared to 38 %). We speculate that in women with such psychopathology, chronic stress results in biological effects that impede successful implantation, thus impairing fertility. Fertility treatment using the IVF paradigm may bypass this negative effect, resulting in high success rates. This hypothesis should be further explored.

It has been hypothesized that unexplained infertility may be related to specific personality and coping styles. We studied two groups of women with explained infertility (EIF, n = 63) and unexplained infertility (UIF, n = 42) undergoing an in vitro fertilization (IVF) cycle. Women completed personality and coping style questionnaires prior to the onset of the cycle, and state depression and anxiety scales before and at two additional time points during the cycle. Almost no in-between group differences were found at any of the measured time points in regards to the Minnesota Multiphasic Personality Inventory-2 validity and clinical scales, Illness Cognitions and Life Orientation Test, or for the situational measures. The few differences found suggest a more adaptive, better coping, and functioning defensive system in women with EIF. In conclusion, we did not find any clinically significant personality differences or differences in depression or anxiety levels between women with EIF and UIF during an IVF cycle. Minor differences found are probably a reaction to the ambiguous medical situation with its uncertain prognosis, amplifying certain traits which are not specific to one psychological structure but rather to the common experience shared by the group. The results of this study do not support the possibility that personality traits are involved in the pathophysiology of unexplained infertility.

Reorganization of the maternal brain upon childbirth triggers the species-typical maternal social behavior. These brief social moments carry profound effects on the infant's brain and likely have a distinct signature in the maternal brain. Utilizing a double-blind, within-subject oxytocin/placebo administration crossover design, mothers' brain was imaged twice using fMRI while observing three naturalistic maternal-infant contexts in the home ecology; 'unavailable', 'unresponsive', and 'social', when mothers engaged in synchronous peek-a-boo play. The social condition elicited greater neural response across the human caregiving network, including amygdala, VTA, hippocampus, insula, ACC, and temporal cortex. Oxytocin impacted neural response primarily to the social condition and attenuated differences between social and non-social stimuli. Greater temporal consistency emerged in the 'social' condition across the two imaging sessions, particularly in insula, amygdala, and TP. Findings describe how mother's brain varies by caregiving experiences and gives salience to moments of social synchrony that support infant development and brain maturation.

PROCEDURE: Twelve regular users of marijuana underwent two positron emission tomography (PET) scans using [18F] Fluorodeoxyglucose (FDG), one while subject to the effects of 17 mg THC, the other without THC. In both sessions, a virtual reality maze task was performed during the FDG uptake period. RESULTS: When subject to the effects of 17 mg THC, regular marijuana smokers hit the walls more often on the virtual maze task than without THC. Compared to results without THC, 17 mg THC increased brain metabolism during task performance in areas that are associated with motor coordination and attention in the middle and medial frontal cortices and anterior cingulate, and reduced metabolism in areas that are related to visual integration of motion in the occipital lobes. CONCLUSION: These findings suggest that in regular marijuana users, the immediate effects of marijuana may impact on cognitive-motor skills and brain mechanisms that modulate coordinated movement and driving.

CONTEXT: Although the behavioral effects of high-dose androgen administration may involve alterations in serotonergic activity, few studies have investigated the impact of androgen withdrawal on the central nervous system in humans. OBJECTIVE: To examine the effects of pharmacologically induced hypogonadism on several cerebrospinal fluid (CSF) systems that could mediate the behavioral concomitants of hypogonadism. DESIGN: Double-blind assessment of the effects of the short-term induction of hypogonadism and subsequent replacement with testosterone and placebo in a crossover design. SETTING: National Institutes of Health, Bethesda, Md. PARTICIPANTS: Twelve healthy male volunteers. INTERVENTIONS: We administered the gonadotropin-releasing hormone agonist leuprolide acetate (7.5 mg intramuscularly every 4 weeks) to the healthy male volunteers, creating a hypogonadal state, and then either replaced testosterone (200 mg intramuscularly) or administered a placebo every 2 weeks for 1 month. MAIN OUTCOME MEASURES: Mood and behavioral symptoms were monitored with daily self-ratings, and lumbar punctures were performed during both hypogonadal (placebo) and testosterone-replaced conditions for CSF levels of steroids and monoamine metabolites. RESULTS: The CSF testosterone, dihydrotestosterone, and androsterone levels were significantly lower during hypogonadism (P=.002, .04, and .046, respectively), but no significant changes were observed in CSF measures of 5-hydroxyindoleacetic acid, homovanillic acid, dehydroepiandrosterone, or pregnenolone. Decreased sexual interest was observed during the hypogonadal state compared with both baseline and testosterone replacement (P=.009) and correlated significantly with CSF measures of androsterone during both hypogonadism and testosterone replacement (r = -0.76 and -0.81, respectively; P<.01). Moreover, the change in severity of decreased sexual interest correlated significantly with the change in CSF androsterone levels between testosterone replacement and hypogonadism (r = -0.68; P<.05). The CSF 5-hydroxyindoleacetic acid and homovanillic acid levels did not correlate significantly with any behavioral or CSF measure. CONCLUSION: These data suggest that the neurosteroid androsterone contributes to the regulation of sexual function in men.

CONTEXT: Alternative and over-the-counter medicines have become increasingly popular choices for many patients who prefer not to take traditional antidepressants. The adrenal androgen and neurosteroid dehydroepiandrosterone (DHEA) is available as over-the-counter hormonal therapy and previously has been reported to have antidepressant-like effects. OBJECTIVE: To evaluate the efficacy of DHEA as a monotherapy treatment for midlife-onset depression. DESIGN: A double-blind, randomized, placebo-controlled, crossover treatment study was performed from January 4, 1996, through August 31, 2002. Settings The National Institute of Mental Health Midlife Outpatient Clinic in the National Institutes of Health Clinical Center, Bethesda, Md. Patients Men (n = 23) and women (n = 23) aged 45 to 65 years with midlife-onset major or minor depression participated in this study. None of the subjects received concurrent antidepressant medications. Intervention Six weeks of DHEA therapy, 90 mg/d for 3 weeks and 450 mg/d for 3 weeks, and 6 weeks of placebo. MAIN OUTCOME MEASURES: The 17-Item Hamilton Depression Rating Scale and Center for Epidemiologic Studies Depression Scale. Additional measures included the Derogatis Interview for Sexual Functioning. Results were analyzed by means of repeated-measures analysis of variance and post hoc Bonferroni t tests. RESULTS: Six weeks of DHEA administration was associated with a significant improvement in the 17-Item Hamilton Depression Rating Scale and the Center for Epidemiologic Studies Depression Scale ratings compared with both baseline (P<.01) and 6 weeks of placebo treatment (P<.01). A 50% or greater reduction in baseline Hamilton Depression Rating Scale scores was observed in 23 subjects after DHEA and in 13 subjects after placebo treatments. Six weeks of DHEA treatment also was associated with significant improvements in Derogatis Interview for Sexual Functioning scores relative to baseline and placebo conditions. CONCLUSION: We find DHEA to be an effective treatment for midlife-onset major and minor depression.

OBJECTIVE: Postpartum depressive disorders are common and symptoms may appear as early as the first 2 weeks postpartum. Data regarding hormone-related risk factors for depressive symptoms occurring in the very early postpartum period are scarce and may be of importance in identifying serious postpartum illness. We examined the association between the reported history of psychiatric symptoms of possible hormonal etiology and very early postpartum depressive symptoms. METHODS: All women (n= 1,800) in a general hospital maternity ward were assessed during the first 3 days after parturition for potential risk factors for postpartum depressive disorders by a self-reported questionnaire and for present mood symptoms (Edinburgh Postnatal Depression Scale, EPDS). The associations between potential risk factors and postpartum depressive symptoms were analysed. RESULTS: The incidence of women with an EPDS >or=10 was 6.8% (88/1,286). Significant risk factors for early postpartum depressive symptoms were a history of mental illness including past postpartum depression (PPD), premenstrual dysphoric disorder (PMDD), and mood symptoms during the third trimester. CONCLUSION: In accordance with other studies, a history of depression was found to be a risk factor for early postpartum mood symptoms. An association was also found between some risk factors of possible hormone-related etiology such as PMDD and third trimester mood symptoms and early postpartum mood symptoms. As such, early postpartum symptoms may indicate vulnerability to subsequent PPD; it may be of importance to assess these risk factors and mood immediately after parturition. A prospective study is needed to determine which of these risk factors is associated with progression to PPD and which resolves as the blues.

OBJECTIVES: The purpose of this study is to compare the baseline psychological distress and symptom profile of women undergoing either medical (with mifepristone) or surgical pregnancy termination and the psychological outcome 2 weeks after the procedure. METHODS: Women (n = 200) given free choice of pregnancy termination method, either medical or surgical, were assessed before pregnancy termination by a demographic questionnaire including questions regarding the choice of the method of pregnancy termination, the Brief Symptom Inventory (BSI), the Spielberger State Anxiety questionnaire and the Rotter Locus of Control Scale. Two weeks after the procedure, the BSI and Spielberger questionnaires were repeated. RESULTS: Women with a smaller number of past pregnancies tended to choose the medical procedure. Reasons for choosing the medical procedure were fear of surgery, anesthesia and of future fertility difficulties. Prior to the procedure, the "medical group" had significantly higher levels of obsessive-compulsive symptoms, guilt and BSI general symptom index score, and a trend for higher interpersonal sensitivity and paranoid ideation. Postprocedure, both groups showed significant decline in anxiety levels and did not differ on most symptom parameters. CONCLUSIONS: Women who chose to have a medical termination are marginally more symptomatic before the procedure than women choosing surgical termination. However, both methods of pregnancy termination resulted in significant reduction in preabortion psychological distress level.
