Course of a major postpartum depressive episode: A prospective 2 years naturalistic follow-up study

Understanding and treating postpartum depression: a narrative review

Postpartum depression (PPD) is an increasingly prevalent but still poorly characterized disorder. Causal and modulating factors include hormones fluctuations, such as estrogen, progesterone, and allopregnolone, pathways imbalances, such as oxytocin and kynurenine, chronobiological factors, and brain imaging alterations. Treatment may differ from the traditional major depression management, while selective serotonin reuptake inhibitors such as sertraline are commonly used and suggested by guidelines, neurosteroids such as brexanolone and the more convenient zuranolone have been recently approved. Newer neurosteroids such as ganaxolone, valaxanolone, and lysaxanolone are currently under development, but also esketamine and psychedelics are promising potential treatments. Other somatic treatments including brain stimulation techniques and light therapy also showed benefit. PPD is therefore increasingly understood as, at least partially, independent from major depressive disorder. Specific and individualized treatments including pharmacological and non-pharmacological therapies are progressively being introduced in the routine clinical practice.

Diagnosis of peripartum depression disorder: A state-of-the-art approach from the COST Action Riseup-PPD

BACKGROUND

Peripartum depression (PPD) is a major depression disorder (MDD) episode with onset during pregnancy or within four weeks after childbirth, as defined in DSM-5. However, research suggests that PPD may be a distinct diagnosis. The goal of this study was to summarize the similarities and differences between PPD and MDD by synthesizing the current research on PPD diagnosis concerning different clinical features and give directions for improving diagnosis of PPD in clinical practice.

METHODS

To lay the groundwork for this narrative review, several databases were searched using general search phrases on PPD and its components of clinical diagnosis.

RESULTS

When compared to MDD, peripartum depression exhibits several distinct characteristics. PPD manifests with a variety of symptoms, i.e., more anxiety, psychomotor symptoms, obsessive thoughts, impaired concentration, fatigue and loss of energy, but less sad mood and suicidal ideation, compared to MDD. Although PPD and MDD prevalence rates are comparable, there are greater cross-cultural variances for PPD. Additionally, PPD has some distinct risk factors and mechanisms such as distinct ovarian tissue expression, premenstrual syndrome, unintended pregnancy, and obstetric complications.

CONCLUSION

There is a need for more in-depth research comparing MDD with depression during pregnancy and the entire postpartum year. The diagnostic criteria should be modified, particularly with (i) addition of specific symptoms (i.e., anxiety), (ii) onset specifier extending to the first year following childbirth, (iii) and change the peripartum onset specifier to either "pregnancy onset" or "postpartum onset". Diagnostic criteria for PPD are further discussed.

The long-term course and prognosis of postpartum depression: a retrospective longitudinal cohort study

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.

Efficacy of contextual therapies in perinatal depression and anxiety: A systematic review and meta-analysis

BACKGROUND

There are previous meta-analyses on the efficacy of cognitive behavioral therapy or mindfulness-based therapies in the perinatal period, but no previous review has focused on contextual therapies as a whole. The aim of this study was to carry out a systematic review and meta-analysis of the efficacy of contextual therapies on depressive and anxious symptoms in women in the perinatal period.

METHODS

A systematic search for randomized clinical trials has been carried out in the PUBMED, CINAHL, Psyc-INFO and Cochrane Library search engines. For the quantitative synthesis, the Morris effect size measure has been used.

RESULTS

A total of 34 RCTs have been found, of which 30 have been used for meta-analysis. The mean effect size of the studies on depression scores was dppc2 = -0.81 (95% CI = -1.12 to -0.50), while it was dppc2 = -1.04 (95% CI = -1.54 to -0.53) in the case of studies on anxiety scores. These effect sizes decreased to medium effect sizes when corrected for publication bias.

LIMITATIONS

The main limitations are the quality of the included studies, publication bias, and the limited number of studies on contextual therapies other than mindfulness-based therapies.

CONCLUSIONS

In conclusion, this systematic review found a large number of efficacy studies on mindfulness-based therapies and a small number of studies on the other contextual therapies. The effect sizes found are consistent with previous meta-analyses in the perinatal period.

A systematic review of screening for perinatal depression and anxiety in community-based settings

Screening for perinatal depression and anxiety in community-based maternal and child health settings may help close the detection and treatment gap among women at higher risk for these conditions. We aim to review perinatal depression and anxiety screening tools, timing, and follow-up processes for positive screens in community-based settings. We conducted a systematic review of the literature to identify papers describing screening and interventions for perinatal depression and anxiety in community-based settings. We identified 49 papers describing 47 studies of perinatal depression or anxiety screening in community-based settings. The Edinburgh Postnatal Depression Scale (EPDS) was the most frequently used screening tool. Referral and referral tracking for those who screened positive for symptoms were inadequately described. Types of training and technical assistance provided for screening varied widely. It is feasible and acceptable to screen for perinatal depression in community settings, but there is a need for systematic research examining which screening tools to use, the ideal frequency of screening, and referral completion rates. There is a lack of information regarding perinatal anxiety screening and a lack of uniformity in training regarding screening in community-based settings. Future studies should compare the efficacy of screening in community-based settings to screening in healthcare settings.

Comparing the Different Manifestations of Postpartum Mental Disorders by Origin, among Immigrants and Native-Born in Israel According to Different Mental Scales

We conducted a prospective study, aimed to study whether the prevalence of mental disorders after birth differs by country of origin. Parturient mothers of Ethiopian origin, Former-USSR (FSU) origin, or nonimmigrant, native-Israeli origin (n = 974, all Jewish) were recruited in hospitals in Israel and were followed 6–8 weeks and one year after birth. General linear models were used to study the associations between origin and mental health, comparing Ethiopian and FSU origin with native-Israeli. Ethiopian and FSU mothers were more likely to report on somatic symptoms, compared with native-Israeli women. Ethiopian origin was negatively and significantly associated with anxiety in all three interviews (β = −1.281, β = −0.678 and β = −1.072, respectively; p < 0.05 in all). FSU origin was negatively associated with depression after birth (β = −0.709, p = 0.036), and negatively associated with anxiety after birth and one-year postpartum (β = −0.494, and β = −0.630, respectively). Stressful life events were significantly associated with all mental disorders in the three time points of interviews. Our findings suggest that immigrants tend to express higher mental distress with somatic symptoms. Additional tools are needed for mental distress screening among immigrants.

Intraoperative pain during caesarean delivery: Incidence, risk factors and physician perception

BACKGROUND

Intraoperative pain is a possible complication of neuraxial anaesthesia for caesarean delivery. There is little information available about its incidence, risk factors and physician perception.

METHODS

Parturients undergoing spinal anaesthesia for elective caesarean delivery were enrolled. Before surgery, parturients were asked about preoperative anxiety on a verbal numerical scale (VNS), anticipated analgesic requirement, postoperative pain levels, Spielberger STATE-TRAIT inventory index, Pain Catastrophizing Scale. After surgery, parturients were asked to answer questions (intraoperative VNS pain). The anaesthesiologist and obstetrician were asked to fill out a questionnaire asking about perceived intraoperative pain. Influence of preoperative anxiety on intraoperative pain (yes/no) was assessed using logistic regression. Mc Fadden's R² was calculated. The agreement in physician perception of intraoperative pain with reported pain by the parturient was examined by calculating Cohen's kappa and 95% Confidence Intervals (CI).

RESULTS

We included 193 parturients in our analysis. Incidence of intraoperative pain was 11.9%. Median intraoperative VNS pain of parturients with pain was 4.0 (1st quartile 4.0; 3rd quartile 9.0). Preoperative anxiety was not a good predictor of intraoperative pain (p-value of β-coefficient = 0.43, Mc Fadden's R²  = 0.01). Including further preoperative variables did not result in a good prediction model. Cohen's kappa between reported pain by parturient and by the obstetrician was 0.21 (95% CI: 0.01, 0.41) and by the anaesthesiologist was 0.3 (95% CI: 0.12, 0.48).

CONCLUSIONS

We found a substantial incidence (11.9%) of intraoperative pain during caesarean delivery. Preoperative anxiety did not predict intraoperative pain. Physicians did not accurately identify parturients' intraoperative pain.

SIGNIFICANCE

Intraoperative pain occurred in 11.9% and severe intraoperative pain occurred in 1.11% of parturients undergoing elective caesarean delivery under spinal anaesthesia. We did not find any preoperative variables that could reliably predict intraoperative pain. Obstetricians and anaesthesiologists underestimated the incidence of intraoperative pain in our cohort and thus, more attention must be put to parturients' pain.

Efficacy of non-invasive brain stimulation in decreasing depression symptoms during the peripartum period: A systematic review

BACKGROUND

Non-invasive brain stimulation (NIBS) techniques have been suggested as alternative treatments to decrease depression symptoms during the perinatal period. These include brain stimulation techniques that do not require surgery and that are nonpharmacological and non-psychotherapeutic. NIBS with evidence of antidepressant effects include repetitive transcranial magnetic stimulation (rTMS), transcranial electric stimulation (TES) and electroconvulsive therapy (ECT).

OBJECTIVES

This systematic review aims to summarize evidence on NIBS efficacy, safety and acceptability in treating peripartum depression (PPD).

METHODS

We included randomized, non-randomized and case reports, that used NIBS during pregnancy and the postpartum. The reduction of depressive symptoms and neonatal safety were the primary and co-primary outcomes, respectively.

RESULTS

rTMS shows promising results for the treatment of PPD, with clinically significant decreases in depressive symptoms between baseline and end of treatment and overall good acceptability. Although the safety profile for rTMS is adequate in the postpartum, caution is warranted during pregnancy. In TES, evidence on efficacy derives mostly from single-arm studies, compromising the encouraging findings. Further investigation is necessary concerning ECT, as clinical practice relies on clinical experience and is only described in low-quality case-reports.

LIMITATIONS

The reduced number of controlled studies, the lack of complete datasets and the serious/high risk of bias of the reports warrant cautious interpretations.

CONCLUSIONS AND IMPLICATIONS

Existing evidence is limited across NIBS techniques; comparative studies are lacking, and standard stimulation parameters are yet to be established. Although rTMS benefits from the most robust research, future multicenter randomized clinical trials are needed to determine the position of each NIBS strategy within the pathways of care.

A systematic review of the association between postpartum depression and neuraxial labor analgesia

BACKGROUND

Postpartum depression (PPD) is the most common complication after childbirth, affecting 10-15% of women. It is associated with serious long-term consequences for the mother and family. Whether or not neuraxial labor analgesia mitigates the risk is uncertain and controversial. The purpose of this review was to summarize studies investigating the association between neuraxial labor analgesia and the incidence of PPD.

METHODS

A systematic literature search for randomized controlled trials and cohort studies reporting the incidence of PPD among parturients who received neuraxial analgesia compared with non-neuraxial or no analgesia. The primary outcome was the incidence of PPD between 5 and 12 weeks' postpartum. Depression was diagnosed using a cutoff score of ≥10 on the Edinburgh Postnatal Depression scale, a validated screening tool. The risk of bias of each study was evaluated, and odds ratios and 95% confidence intervals calculated from raw data or reported as adjusted odds ratios.

RESULTS

Eleven observational studies involving 5717 patients were included. Three studies had a critical risk, three a serious risk, and five a moderate risk of bias. Two studies reported significantly lower odds for PPD associated with neuraxial analgesia compared with non-neuraxial or no analgesia, whereas the odds ratios in the remaining nine studies were not significantly different.

CONCLUSIONS

Our systematic review did not find compelling evidence for an association between PPD and labor analgesia. Studies were heterogenous in nature and had a high risk of bias. Further research controlling for confounding factors is recommended to determine if a relationship exists.

Perinatal death triples the prevalence of postpartum depression among women in Northern Uganda: A community-based cross-sectional study

INTRODUCTION

Deaths during the perinatal period remain a big challenge in Africa, with 38 deaths per 1000 pregnancies in Uganda. The consequences of these deaths can be detrimental to the women; some ending up with postpartum depression. We examined the association between perinatal death and postpartum depression among women in Lira district, Northern Uganda.

METHODS

We conducted a community-based cross-sectional study of 1,789 women. Trained research assistants screened women for postpartum depressive symptoms on day 50 postpartum using the Edinburgh postpartum depression scale (EPDS). Socio-demographic, economic, birth and survival status of the neonate were collected during pregnancy and within one week postpartum. We used generalized estimating equation for the Poisson family with a log link using Stata to estimate the prevalence ratio of the association between postpartum depressive symptoms (EPDS scores ≥14) and perinatal death. Mothers who lost their babies between 7-49 days postpartum were excluded.

RESULTS

Of the 1,789 participants symptomatically screened for postpartum depression, 377 (21.1%) [95% confidence interval (95%CI): 17.2%, 23.0%] had probable depressive symptoms. The prevalence of postpartum depressive symptoms among the 77 women who had experienced perinatal death (37 stillbirths and 40 early neonatal deaths (≤7 days of life)) was 62.3% [95% CI: 50.8%, 72.6%] compared to 19.2% [95% CI: 17.4%, 21.2%], among 1,712 with live infants at day 50 postpartum. Women who had experienced a perinatal death were three times as likely to have postpartum depressive symptoms as those who had a live birth [adjusted prevalence ratio 3.45 (95% CI: 2.67, 4.48)].

CONCLUSIONS

The prevalence of postpartum depressive symptoms, assessed by EPDS, was high among women who had had a perinatal death in Northern Uganda. Women experiencing a perinatal death need to be screened for postpartum depressive symptoms in order to intervene and reduce associated morbidity.

Patterns of Positivity: Positive Affect Trajectories Among Infants of Mothers with a History of Depression

This study examined positive affect (PA) trajectories over the first year of life among infants of mothers with a history of depression (N = 191) as well as predictors (i.e., maternal prenatal and postpartum depression symptoms, maternal parenting behaviors) of those trajectories. Infant PA was observed in play and feeding tasks during lab visits at 3, 6, and 12 months of age; parenting behaviors were observed at 3 months. Mothers completed questionnaires regarding their symptoms of depression throughout the prenatal period and during the first 3 months postpartum. Growth curve analyses indicated that infant PA increased across time, and this finding replicated across both the play and feeding tasks, though increases slowed over time. Neither maternal prenatal nor postpartum depression symptoms predicted infants' PA trajectories, but mothers' PA, positive parenting, and disengaged parenting were associated with infant PA during the play task. Our finding that infant PA increased over the first year postpartum suggests PA trajectories among infants of mothers with a history of depression may be indices of resilience, despite risks associated with their mothers' history of depression. Furthermore, this study highlights parenting behaviors that may be important targets of prevention and early intervention efforts to bolster infant PA.

Interrupting the Pathway from Gestational Diabetes Mellitus to Type 2 Diabetes: The Role of Primary Care

OBJECTIVE

Our objective was to describe patient-, provider-, and health systems-level factors associated with likelihood of obtaining guideline-recommended follow-up to prevent or mitigate early-onset type 2 diabetes after a birth complicated by gestational diabetes mellitus (GDM).

METHODS

This study presents a retrospective cohort analysis of de-identified demographic and health care system characteristics, and clinical claims data for 12,622 women with GDM who were continuously enrolled in a large, national U.S. health plan from January 31, 2006, to September 30, 2012. Data were obtained from the OptumLabs Data Warehouse. We extracted 1) known predictors of follow-up (age, race, education, comorbidities, GDM severity); 2) novel factors that had potential as predictors (prepregnancy use of preventive measures and primary care, delivery hospital size); and 3) outcome variables (glucose testing within 1 and 3 years and primary care visit within 3 years after delivery).

RESULTS

Asian ethnicity, higher education, GDM severity, and delivery in a larger hospital predicted greater likelihood of post-GDM follow-up. Women with a prepregnancy primary care visit of any type were two to three times more likely to receive postpartum glucose testing and primary care at 1 year, and 3.5 times more likely to have obtained testing and primary care at 3 years after delivery.

CONCLUSIONS

A history of use of primary care services before a pregnancy complicated by GDM seems to enhance the likelihood of postdelivery surveillance and preventive care, and thus reduce the risk of undetected early-onset type 2 diabetes. An emphasis on promoting early primary care connections for women in their early reproductive years, in addition to its overall value, is a promising strategy for ensuring follow-up testing and care for women after complicated pregnancies that forewarn risk for later chronic illness. Health systems should focus on models of care that connect primary and reproductive/maternity care before, during, and long after pregnancies occur.
