RESUMEN
OBJECTIVES: Perinatal psychopathology can be damaging. This study examined the strength of the associations between risk factors and all perinatal mood and anxiety disorder symptoms while assessing the mediating effect of experiential avoidance. METHOD: Participants (N = 246) completed assessments during pregnancy (28-32 weeks) and the postpartum (6-8 weeks). Structural equation modeling (SEM) was used to examine associations between risk factors and latent factors: distress (composed of depression, generalized anxiety, irritability, and panic symptoms); fear (social anxiety, agoraphobia, specific phobia, and obsessive-compulsive); and bipolar (mania and obsessive-compulsive). RESULTS: During pregnancy, past psychiatric history, anxiety sensitivity, maladaptive coping, and age were significant risk factors. In the postpartum, negative maternal attitudes and past psychiatric history were only risk factors for symptoms that composed distress. Experiential avoidance mediated the relation between maladaptive coping and symptoms that composed fear. CONCLUSION: It is important to assess for psychological risk factors starting in pregnancy. This study identified critical risk factors that are associated with the underlying commonality among perinatal mood and anxiety symptoms. Some of the risk factors as well as the mediator are malleable (negative maternal attitudes, experiential avoidance), creating new possibilities for prevention and treatment of perinatal mood and anxiety disorder symptoms.

There is heightened risk for maternal posttraumatic stress disorder (PTSD) during the perinatal period. However, it is unclear whether pregnancy and childbirth uniquely contribute to PTSD symptoms above and beyond elevations in negative affectivity that commonly occur among postpartum women (e.g., irritability, fatigue, depressed mood) and past trauma exposure. The present study explored the associations between childbirth stressors and trauma-related distress (TRD; intrusion and avoidance symptoms) across the 2 years following childbirth in a community sample of women (n = 159). Maternal TRD was assessed at pregnancy and four additional timepoints across 2 years postpartum. At pregnancy, mothers completed surveys measuring exposure to trauma and pregnancy-related anxiety. They also reported on pregnancy and childbirth complications across the first 6 months postpartum. Consistent with predictions, labor/delivery complications uniquely predicted increased maternal intrusions during the first 6 months postpartum above and beyond past trauma exposure. Furthermore, growth mixture models identified a subset of women with intrusion symptoms that persisted up to 2 years postpartum and, on average, exceeded the screening threshold for PTSD. Women who experienced greater labor complications were more likely to exhibit this clinical profile relative to low, stable symptoms. Findings highlight the importance of ongoing screening for TRD across the first 2 years postpartum, particularly among women who experience greater labor/delivery complications.

The level of support from family members-and degree of family dysfunction-can shape the onset and course of maternal postpartum depression (PPD). In spite of this, family members are typically not included in treatments for PPD. Developing and disseminating intervention approaches that involve partners or other family members may lead to more effective treatment for perinatal women and potentially promote improved family functioning and wellbeing of multiple members of the family. To evaluate the feasibility and acceptability of a family-based treatment for PPD, we conducted an open pilot trial with 16 postpartum mother-father couples (N = 32 participants) and measured session attendance, patient satisfaction, and changes in key symptoms and functional outcomes. At the time of enrollment, mothers were 1-7 months postpartum, met criteria for major depressive disorder, and had moderate-severe symptoms of depression. Treatment involved 10-12 sessions attended by the mother along with an identified family member (all fathers) at each session. Findings provide strong support for the acceptability and feasibility of the intervention: session attendance rates were high, and participants evaluated the treatment as highly acceptable. Improvements in depression were observed among both mothers and fathers, and family functioning improved by the endpoint across several domains. Symptomatic and functional gains were sustained at follow-up. The current findings provide support for a larger randomized trial of family-based treatment for PPD.

BACKGROUND: Emotional distress is frequently experienced by mothers whose newborns are hospitalized in a neonatal intensive care unit (NICU). Among these women, there is a critical need for emotional support conveniently delivered at the newborn's point of care by a trusted and medically knowledgeable professional: a NICU nurse. One promising way to enhance in situ delivery of emotional care is to have a NICU nurse provide Listening Visits (LVs), a brief support intervention developed expressly for delivery by nurses to depressed postpartum women. OBJECTIVES: This trial assessed the feasibility of having NICU nurses deliver LVs to emotionally distressed mothers of hospitalized newborns and compared depression outcomes in a small sample of participants randomized to LVs or usual care (UC). METHODS: In this pilot randomized controlled trial, emotionally distressed mothers of hospitalized newborns were randomized to receive up to six LVs from a NICU nurse or UC from a NICU social worker. To assess change in depression symptoms, women were invited to complete the Inventory of Depression and Anxiety Symptoms-General Depression Scale at enrollment and 4 and 8 weeks post-enrollment. RESULTS: Depression symptoms declined over time for both groups, with no difference between the two groups. A post hoc analysis of reliable change found higher rates of improvement at the 4-week assessment among recipients of LVs than UC. DISCUSSION: NICU nurses successfully implemented LVs during this trial. Depression symptom scores did not significantly differ in the two groups posttreatment or at follow-up. Nevertheless, post hoc analyses indicated comparatively higher rates of clinical improvement immediately after LVs, suggesting the intervention can reduce maternal depression early on when women are most distressed.

Obsessive-compulsive disorder (OCD) symptoms are more likely to develop or be exacerbated during pregnancy and the postpartum period, which can cause significant distress and impairment. However, the disorders grouped with OCD in the DSM-5, obsessive-compulsive and related disorders (OCRD; e.g., hoarding disorder (HD), body dysmorphic disorder (BDD), trichotillomania (TTM), excoriation disorder (ED)), have rarely been examined in the perinatal period. This study aimed to explore (1) the prevalence of all clinically significant OCRD symptoms in pregnancy and the postpartum period and (2) the correlations between OCRD psychopathology and postpartum functioning. Participants were recruited during their second trimester of pregnancy from a Midwestern medical center. Participants completed an online questionnaire and a semi-structured clinical interview during pregnancy (28-32 weeks' gestation, N = 276) and the postpartum period (6-8 weeks, N = 221). BDD and OCD symptoms were the most prevalent. In pregnancy, 14.9% (N = 41) of participants endorsed clinically significant BDD symptoms and 6.2% (N = 17) endorsed clinically significant OCD symptoms. In the postpartum period, 11.8% (N = 26) endorsed clinically significant BDD symptoms and 14% (N = 31) endorsed clinically significant OCD symptoms. Poorer postpartum functioning was associated with elevated OCRD symptoms in pregnancy and postpartum. OCRD symptoms occur during pregnancy and the postpartum period at rates similar or higher than other life periods. Elevated OCRD symptoms are associated with poorer postpartum functioning across domains. Future research should explore how all OCRD symptoms may affect functioning in the perinatal period, not only OCD symptoms.

Existing research suggests that childbirth may be a significant trigger of posttraumatic stress symptoms (PTSS). The current study examined whether subjective birthing experiences and objective childbirth characteristics mediated the association between predisposing psychosocial factors measured during pregnancy (e.g., fear of childbirth, history of trauma, and social support) and PTSS during the postpartum period. Women were recruited during pregnancy from a large Midwestern hospital. Symptoms of posttraumatic stress, obsessive compulsive disorder (OCD), and depression, as well as PTSS-related risk factors, including social support, lifetime trauma exposure, fear of childbirth, subjective perceptions, and objective characteristics of childbirth, were measured during pregnancy and 4, 8, and 12 weeks postpartum. A path model revealed that subjective perceptions of childbirth mediated the association between fear of childbirth and PTSS at 4 weeks postpartum. Objective childbirth characteristics mediated the association between fear of childbirth and PTSS at 8 weeks postpartum, and there was a direct association between fear of childbirth and PTSS. Subjective perceptions of childbirth also mediated the effect of fear of childbirth on PTSS at 4 weeks postpartum when controlling for OCD symptoms. Further, the direct effect of fear of childbirth on PTSS at 8 weeks postpartum remained significant when controlling for OCD symptoms. The current study emphasizes the importance of fear of childbirth and subjective and objective birthing experiences in predicting postpartum psychopathology. Future research should examine these models in diverse and at-risk samples. Valid assessments and effective interventions for perinatal PTSS should be explored.

Underserved women of color experience high rates of perinatal affective disorders, but most research to date on the natural history of these disorders has been conducted on White women. The present study investigated longitudinal changes in anxiety and depression in a sample of perinatal non-Hispanic Black and Latina women. Categorical (yes/no) measures of positive anxiety and depression screens, as well as total symptom scores, were measured longitudinally across the perinatal period in 178 women (115 non-Hispanic Black, 63 Latina) using the CAT-MH™, a computerized adaptive test. Time (up to 4 visits) and race/ethnicity effects were assessed in linear mixed effects models. Rates of positive anxiety screenings were 13.6%, 3.2%, 8.5%, and 0% in Latina women and 2.6%, 4.2%, 6.1%, and 5.8% in non-Hispanic Black women in the 1st, 2nd, and 3rd trimesters, and postpartum, respectively. Rates of positive anxiety screenings overall were highest in the first trimester (OR = 0.20; 95% CI 0.04-0.98), and there was a significant time-by-race/ethnicity interaction for positive anxiety screens (OR = 8.88; 95% CI 1.42-55.51), as positive screens were most frequent in the first trimester and sharply declined for Latina women, while rates were relatively consistent across the perinatal period in non-Hispanic Black women. Rates of positive depression screens did not change over time, but there was a trend (OR = 1.93; 95% CI 0.93-4.03) for a time-by-race/ethnicity interaction in a direction similar to that seen for anxiety. The odds of positive anxiety screens vary by race/ethnicity and trimester, suggesting that anxiety screening and anxiety interventions may be most resourcefully used in the first trimester for Latina women in particular.

Depression in the postpartum period impacts approximately 13-26% of the general population. This number can be much higher for rural veteran women who face additional barriers to accessing specialized mental health services due to isolation and cultural factors. This study reports on a program evaluation of MomMoodBooster, a coach-supported internet-delivered CBT program for the treatment of maternal depression in veteran women. Repeated measures ANOVA, run with this sample of 326 women, demonstrated an overall positive effect size across outcome measures and engagement with no differences found between rural women and their urban counterparts. Some differences between urban and rural participants were found in total and average time spent with coaches as well as ratings of coach helpfulness, possibly indicating some cultural differences between coaches and rural women that need to be addressed. These results and the results of earlier trials suggest that MomMoodBooster can be a valid and efficacious option for reaching under-served veteran populations with specialized postpartum mental health support and is as effective with rural women as with urban women.

BACKGROUND: The postpartum period is a vulnerable time for the development of depression. While perinatal depression has been well studied, intrusive thoughts related to the infant and classic obsessive-compulsive (OC) symptoms (e.g. chequering, ordering and cleaning) are also common in the postpartum and less well understood. OBJECTIVE: The present study investigated the associations among depressive symptoms, intrusive thoughts, and OC symptoms and their relation to the quality of the mother-infant relationship, particularly in the realm of maternal responsiveness. METHODS: Participants (N = 228) were recruited after delivery from a large Midwestern academic medical centre. At 2 and 12-week postpartum, participants completed self-report questionnaires that assessed demographics, depressive and OC symptoms, postpartum-specific intrusive thoughts and accompanying neutralising strategies, and maternal responsiveness. RESULTS: At 12-week postpartum, maternal responsiveness was significantly lower for participants that endorsed intrusive thoughts, neutralising strategies or OC symptoms of clinical significance. More severe intrusive thoughts and neutralising strategies were associated with maternal responsiveness but not predictive after accounting for depressive symptoms; depressive symptoms were associated with lower levels of maternal responsiveness across the postpartum. CONCLUSIONS: A sizable number of postpartum women experience clinically significant postpartum-specific intrusive thoughts and utilise neutralising strategies, especially in the context of postpartum depressive symptoms. Depressive symptoms have the most influence on maternal responsiveness but it is also important to target intrusive thoughts and OC symptoms in the context of postpartum depression to promote the welfare of new mothers and their offspring.

BACKGROUND: Home visitation is a popular mechanism for supporting parents and their young children. Breastfeeding is often promoted by home visitors due to its health benefits. However, maternal depression may interfere with breastfeeding. Thus, home visitors may be attempting to encourage health-promoting behaviors like breastfeeding, but maternal depression may interfere with engagement in those behaviors. METHOD: The data for this study were provided by the Des Moines Healthy Start and the Empowerment Family Support Project (DMHSP). We analyzed the relation between depression and breastfeeding for 364 women. RESULTS: First, rates of elevated depression scores in this sample of women (8.7%-21.4% of women) were lower than rates of elevated depression scores reported in other studies of women enrolled in home visitation (30%-50% of women). Second, rates of breastfeeding at 3 months postpartum in this sample (56% of women) were higher than rates of breastfeeding reported in the general population (51% of women). Third, Non-Hispanic White women were significantly less likely to breastfeed compared to other racial groups. Fourth, average Edinburgh Postnatal Depression Scale (EPDS) scores during the first 3 months postpartum, but not during pregnancy, were predictive of likelihood to breastfeed at 3 months postpartum, even after accounting for demographic characteristics. CONCLUSION: Addressing maternal depression during the early postpartum period may increase the likelihood of engaging in breastfeeding.

The current study examined the moderating role of social support in the association between prenatal maternal stress (PNMS) and childhood body mass index (BMI) in the context of the Iowa floods of 2008. In addition, the mediating role of offspring birthweight was examined in the association between PNMS and childhood BMI. We recruited women from eastern Iowa who were pregnant in 2008 when disastrous floods occurred. Self-report measures of PNMS and cognitive appraisal of the flood's consequences were obtained shortly after the disaster. Social support was assessed during pregnancy. Offspring anthropometric measures were collected at birth and 30 months. Moderated mediation results indicated that greater PNMS predicted greater BMI at age 30 months through effects on higher birthweight as a mediator, but only for participants with low social support. High social support (satisfaction or number) buffered the effect of PNMS or a negative appraisal of the flood on birthweight. The combination of high PNMS or a negative appraisal of the flood's consequences and low social support resulted in higher offspring birthweight, which predicted greater BMI at 30 months. Providing strong social support to pregnant women following a stressor might buffer the effects of PNMS on offspring birthweight and later obesity.

Poor postnatal mental health is a major public health issue, and risk factors include experiencing adverse life events during pregnancy. We assessed whether midwifery group practice, compared to standard hospital care, would protect women from the negative impact of a sudden-onset flood on postnatal depression and anxiety. Women either received midwifery group practice care in pregnancy, in which they were allocated a primary midwife who provided continuity of care, or they received standard hospital care provided by various on-call and rostered medical staff. Women were pregnant when a sudden-onset flood severely affected Queensland, Australia, in January 2011. Women completed questionnaires on their flood-related hardship (objective stress), emotional reactions (subjective stress), and cognitive appraisal of the impact of the flood. Self-report assessments of the women's depression and anxiety were obtained during pregnancy, at 6 weeks and 6 months postnatally. Controlling for all main effects, regression analyses at 6 weeks postpartum showed a significant interaction between maternity care type and objective flood-related hardship and subjective stress, such that depression scores increased with increasing objective and subjective stress with standard care, but not with midwifery group practice (continuity), indicating a buffering effect of continuity of midwifery carer. Similar results were found for anxiety scores at 6 weeks, but only with subjective stress. The benefits of midwifery continuity of carer in pregnancy extend beyond a more positive birth experience and better birthing and infant outcomes, to mitigating the effects of high levels of stress experienced by women in the context of a natural disaster on postnatal mental health.

Postpartum depression is a significant public health problem affecting almost 600,000 US women every year. It may arise de novo in the postpartum period or continue from pregnancy. A number of evidence-based psychotherapies and medical treatments exist for major depression and postpartum depression. The obstetrical team has many opportunities to identify high risk and depressed women and refer them to mental health professionals or begin treatment with antidepressant medication. Careful assessment of risk factors for postpartum depression during pregnancy and monitoring depressive symptoms during pregnancy and the postpartum period will lead to better outcomes for women and their families.

OBJECTIVES: The present study developed normative data for the expanded version of the Inventory of Depression and Anxiety Symptoms (IDAS-II). The IDAS-II is a self-report measure containing 18 factor-analytically derived scales, each assessing a specific symptom of internalizing disorders, including depression, anxiety disorders, OCD, bipolar disorder, and PTSD. These normative data were used to examine group differences in internalizing symptoms across demographic characteristics. METHOD: A total of 1,836 Mechanical Turk users (47.6% male; mean age = 35.6) completed the IDAS-II; the sample was weighted to be representative of the U.S. population on gender, age, and race/ethnicity. RESULTS: Percentiles were derived for each of the IDAS-II scales. Age was the demographic characteristic most consistently associated with lower internalizing symptoms. CONCLUSIONS: The present study provides information on the distribution of specific internalizing symptoms in a large national sample, as well as on how these symptoms are related to demographic characteristics.

Depression during pregnancy is highly prevalent and is associated with increased risk of a variety of negative psychological and medical outcomes in both mothers and offspring. Antenatal depression often co-occurs with significant anxiety, potentially exacerbating morbidities for women and their children. However, screening during the antenatal period is frequently limited to assessment of depression so that other significant comorbid disorders may be missed. Follow-up assessment by clinicians has similarly focused primarily on detection of depressive symptoms. Anxiety, obsessive compulsive disorder, and post-traumatic stress disorder, among others, often go undetected in perinatal care settings, even when depression is identified. Failing to recognize these comorbid diagnoses may lead to inadequate treatment or only partial alleviation of distress. Consequently, screening for and assessment of comorbid disorders is warranted. In this study, 382 pregnant women (M age = 25.8 [SD = 5.3] years, 85.0% Caucasian) receiving care at a university hospital clinic and Maternal Mental Health Care centers in eastern Iowa and who screened positive for depression on the Beck Depression Inventory completed the Structured Clinical Interview for DSM-IV to assess comorbid mental health symptoms and diagnoses. Overall, findings demonstrate high rates of anxiety disorders among women both with and without current major depression, although depressed women reported higher rates of generalized anxiety disorder and post-traumatic stress disorder. Notably, however, incidence-specific symptoms were comparable across groups. Routine screening of both anxiety and depression during pregnancy should be conducted.

Maternal depression is a prevalent public health problem, particularly for low-income mothers of young children. Intervention development efforts, which often focus on surmounting instrumental barriers to care, have not successfully engaged and retained women in treatment. Task-sharing approaches like Listening Visits (LV) could overcome key instrumental and psychological barriers by leveraging the access of trusted, community caregivers to deliver treatment. A recent randomized controlled trial (RCT) demonstrated the efficacy of LV delivered by non-mental-health providers as compared to usual care. The present report presents results from a follow-up phase of that RCT during which participants who had completed LV were followed for an additional 8 weeks and completed measures of depression and quality of life. In addition, participants who were initially randomized to the wait-list control group received LV and were assessed. Treatment gains previously observed in participants completing LV were enhanced during the 8-week follow-up period. Participants receiving LV during the follow-up period experienced significant improvement in depressive symptoms. Results demonstrate the sustainability of LV delivered by non-mental-health providers, and provide preliminary evidence for the replicability of this approach in a sample of predominately low-income pregnant women and mothers of young children.

Preclinical development of and research on potential Middle East respiratory syndrome coronavirus (MERS-CoV) medical countermeasures remain preliminary; advancements are needed before most countermeasures are ready to be tested in human clinical trials. Research priorities include standardization of animal models and virus stocks for studying disease pathogenesis and efficacy of medical countermeasures; development of MERS-CoV diagnostics; improved access to nonhuman primates to support preclinical research; studies to better understand and control MERS-CoV disease, including vaccination studies in camels; and development of a standardized clinical trial protocol. Partnering with clinical trial networks in affected countries to evaluate safety and efficacy of investigational therapeutics will strengthen efforts to identify successful medical countermeasures.

BACKGROUND: The interaction of depression and anesthesia and surgery may result in significant increases in morbidity and mortality of patients. Major depressive disorder is a frequent complication of surgery, which may lead to further morbidity and mortality. LITERATURE SEARCH: Several electronic data bases, including PubMed, were searched pairing "depression" with surgery, postoperative complications, postoperative cognitive impairment, cognition disorder, intensive care unit, mild cognitive impairment and Alzheimer's disease. REVIEW OF THE LITERATURE: The suppression of the immune system in depressive disorders may expose the patients to increased rates of postoperative infections and increased mortality from cancer. Depression is commonly associated with cognitive impairment, which may be exacerbated postoperatively. There is evidence that acute postoperative pain causes depression and depression lowers the threshold for pain. Depression is also a strong predictor and correlate of chronic post-surgical pain. Many studies have identified depression as an independent risk factor for development of postoperative delirium, which may be a cause for a long and incomplete recovery after surgery. Depression is also frequent in intensive care unit patients and is associated with a lower health-related quality of life and increased mortality. Depression and anxiety have been widely reported soon after coronary artery bypass surgery and remain evident one year after surgery. They may increase the likelihood for new coronary artery events, further hospitalizations and increased mortality. Morbidly obese patients who undergo bariatric surgery have an increased risk of depression. Postoperative depression may also be associated with less weight loss at one year and longer. The extent of preoperative depression in patients scheduled for lumbar discectomy is a predictor of functional outcome and patient's dissatisfaction, especially after revision surgery. General postoperative mortality is increased. CONCLUSIONS: Depression is a frequent cause of morbidity in surgery patients suffering from a wide range of conditions. Depression may be identified through the use of Patient Health Questionnaire-9 or similar instruments. Counseling interventions may be useful in ameliorating depression, but should be subject to clinical trials.

BACKGROUND: Retrospective studies suggest that maternal exposure to a severe stressor during pregnancy increases the fetus' risk for a variety of disorders in adulthood. Animal studies testing the fetal programming hypothesis find that maternal glucocorticoids pass through the placenta and alter fetal brain development, particularly the hypothalamic-pituitary-adrenal axis. However, there are no prospective studies of pregnant women exposed to a sudden-onset independent stressor that elucidate the biopsychosocial mechanisms responsible for the wide variety of consequences of prenatal stress seen in human offspring. The aim of the QF2011 Queensland Flood Study is to fill this gap, and to test the buffering effects of Midwifery Group Practice, a form of continuity of maternity care. METHODS/DESIGN: In January 2011 Queensland, Australia had its worst flooding in 30 years. Simultaneously, researchers in Brisbane were collecting psychosocial data on pregnant women for a randomized control trial (the M@NGO Trial) comparing Midwifery Group Practice to standard care. We invited these and other pregnant women to participate in a prospective, longitudinal study of the effects of prenatal maternal stress from the floods on maternal, perinatal and early childhood outcomes. Data collection included assessment of objective hardship and subjective distress from the floods at recruitment and again 12 months post-flood. Biological samples included maternal bloods at 36 weeks pregnancy, umbilical cord, cord blood, and placental tissues at birth. Questionnaires assessing maternal and child outcomes were sent to women at 6 weeks and 6 months postpartum. The protocol includes assessments at 16 months, 2½ and 4 years. Outcomes include maternal psychopathology, and the child's cognitive, behavioral, motor and physical development. Additional biological samples include maternal and child DNA, as well as child testosterone, diurnal and reactive cortisol. DISCUSSION: This prenatal stress study is the first of its kind, and will fill important gaps in the literature. Analyses will determine the extent to which flood exposure influences the maternal biological stress response which may then affect the maternal-placental-fetal axis at the biological, biochemical, and molecular levels, altering fetal development and influencing outcomes in the offspring. The role of Midwifery Group Practice in moderating effects of maternal stress will be tested.
