[Review about smoking in pregnancy: prevalence, sociodemographic profile, perinatal depression, psychological variables involved and treatment]. / Revisión del tabaquismo en el embarazo: prevalencia, perfil sociodemográfico, depresión perinatal, variables psicológicas implicadas y tratamiento.

OBJECTIVE: Smoking is a Public Health problem. Half of all women smokers continue to smoke during pregnancy, putting their health and that of their foetus at risk. The aim of this review was to synthesise the main studies on the prevalence and sociodemographic, psychological and obstetric profile of women who smoke during pregnancy, the relationship of stress, personality and depression with smoking during pregnancy and the most effective treatments. METHODS: We conducted a literature review in the MEDLINE and PsycInfo databases from 2013 to 2023 on the most relevant aspects of smoking in pregnancy, including thirty studies. RESULTS: The prevalence of smoking in pregnancy is 15.7% in Spain. The socio-demographic profile of women who smoke during pregnancy is that of women with a low socioeconomic and educational level, generally without a partner or with partners who smoke and are unemployed. A relationship had been found between smoking in pregnancy and a higher probability of suffering from perinatal depression. High self-perceived stress may be a predictor variable for continued smoking in pregnancy. Personality traits such as high neuroticism appear to be related to smoking in pregnancy. Intervention to help pregnant women quit smoking must be tailored to the profile of the pregnant woman to be effective. Cognitive behavioural interventions show efficacy, especially in the long term. CONCLUSIONS: In order to design effective prevention and intervention programmes to help pregnant women quit smoking, not only the socio-demographic profile of the pregnant women should be taken into account, but also psychological variables such as personality and stress. These programmes should include cognitive behavioural interventions that teach adaptive stress management strategies to maximise their effectiveness. Special emphasis should be placed on reaching those women with the most disadvantaged profiles.

OBJETIVO: El tabaquismo es un problema de Salud Pública. La mitad de las mujeres fumadoras continúan haciéndolo en el embarazo, poniendo en riesgo su salud y la del feto. El objetivo de esta revisión fue sintetizar los principales estudios sobre la prevalencia y el perfil sociodemográfico, psicológico y obstétrico de la mujer fumadora en el embarazo, la relación del estrés, la personalidad y la depresión con el tabaquismo durante el embarazo y los tratamientos más eficaces. METODOS: Se llevó a cabo una revisión bibliográfica en las bases de datos MEDLINE y PsycInfo desde el año 2013 al 2023 sobre los aspectos más relevantes del tabaquismo en el embarazo, incluyéndose treinta estudios. RESULTADOS: La prevalencia del tabaquismo en el embarazo se sitúa en un 15,7% en España. El perfil sociodemográfico de la mujer fumadora en el embarazo es de aquella con bajo nivel socioeconómico y educativo, generalmente sin pareja o con parejas fumadoras, y sin trabajo. Se encontró relación entre fumar en el embarazo y mayor probabilidad de padecer depresión perinatal. Un alto estrés autopercibido es posible que sea una variable predictora de continuar fumando en el embarazo. Algunos rasgos de personalidad como elevado neuroticismo parecen estar relacionados con el tabaquismo en el embarazo. La intervención para ayudar a dejar de fumar a las embarazadas debe adaptarse al perfil de la misma para que sea eficaz. Las intervenciones cognitivo-conductuales muestran su eficacia, especialmente a largo plazo. CONCLUSIONES: Para diseñar programas de prevención e intervención eficaces que ayuden a las gestantes a dejar de fumar se debe tener en cuenta no solo el perfil sociodemográfico de las mismas, sino variables psicológicas como la personalidad y el estrés. Estos programas deben incluir intervenciones cognitivo-conductuales que enseñen estrategias adaptativas de gestión del estrés para maximizar su eficacia. Se debe poner especial énfasis en que estos programas lleguen a aquellas mujeres con perfil más desfavorecido.

Psychometric Properties of the Online Version of the General Anxiety Disorder-7 (GAD-7): A Longitudinal Study in Pregnant and Postpartum Spanish Women.

BACKGROUND: The use of online questionnaires to assess common mental disorders such as perinatal anxiety has spread due to the proliferation of Internet-based psychological interventions and research. This study analyses the validity and reliability of the online version of the Generalized Anxiety Disorder-7 (GAD-7) in a sample of pregnant and postpartum Spanish women. METHOD: A total of 3082 pregnant (n = 1260) and postpartum (n = 1822) women were recruited via the Internet and underwent three follow-up evaluations during a six-month period. RESULTS: A one-factor solution was assigned by Exploratory Factor Analysis and confirmed by Confirmatory Factor Analysis for both pregnant (CFI = 0.998; RMSEA = 0.035) and postpartum (CFI = 0.998; RMSEA = 0.038) women. The one-factor model showed strict invariance across groups. Validity was confirmed by assessing correlations between GAD-7, the Edinburgh Postnatal Depression Scale, and the 10-item Posttraumatic Stress Disorder checklist at three time points. The reliability coefficient was .92 for the two groups. CONCLUSIONS: This study shows that the Spanish online GAD-7 version has good psychometric properties and can be used to assess anxiety symptoms during the perinatal period.

Hygiene-based measures for the prevention of cytomegalovirus infection in pregnant women: a systematic review.

BACKGROUND: Human Cytomegalovirus (HCMV) is the most frequent congenital infection worldwide causing important sequelae. However, no vaccine or antiviral treatments are currently available, thus interventions are restricted to behavioral measures. The aim of this systematic review was to assess evidence from available intervention studies using hygiene-based measures to prevent HCMV infection during pregnancy. METHODS: Studies published from 1972 to 2023 were searched in Medline, PsycInfo, and Clinical Trials (PROSPERO, CRD42022344840) according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Methodological quality was assessed by two authors, using ROBE-2 and MINORS. RESULTS: After reviewing 6 selected articles, the outcome analysis suggested that implementation of hygiene-based interventions during pregnancy prevent, to some extent, the acquisition of congenital HCMV. CONCLUSIONS: However, these conclusions are based on limited and low-quality evidence available from few studies using this type of intervention in clinical practice. Thus, it would be necessary to perform effective and homogeneous intervention studies using hygiene-based measures, evaluated in high-quality randomized controlled trials (RCTs).

Self-harm thoughts among postpartum women - associated factors.

BACKGROUND: Even though in many countries suicide is the leading cause of maternal deaths during the postpartum period, the prevalence of thoughts of self-harm (SHTs), an important risk factor for suicide attempts, is still not well documented. AIM: We aimed to investigate the prevalence of SHTs in a Polish cohort of postpartum women and identify socio-demographic and maternal mental health factors associated with experiencing SHTs. METHOD: 1545 women took part in a midwife-led postpartum depression (PPD) screening. 337 of them reported SHTs. The Edinburgh Postpartum Depression Scale (EPDS) was administered. Specifically, we used an abbreviated 5-item version to assess depression symptoms, item 10 to assess SHTs, a composite score of items 1 and 2 - anhedonia, and a composite score of items 3, 4, and 5 - anxiety. Logistic regression analyses were performed to examine associations between variables. RESULTS: Approximately 2% (n = 337) of women self-reported experiencingSHTs. Within the group of postpartum mothers who self-reported SHTs, 65.60% (n = 221) manifested the symptoms of PPD, and 56.40% (n = 190) - of anxiety. The symptoms of PPD, a mood disorder diagnosed in the past, and younger age were predictors of SHTs. CONCLUSION: The results of this study can contribute to the development of prevention strategies: analysing separately items from PPD screening questionnaires focusing on SHTs can be an important part of prevention. The lack of the symptoms of PPD and anxiety risk does notexclude experiencing SHTs.

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.

"Social support and stressful life events: risk factors for antenatal depression in nulliparous and multiparous women".

Nulliparous (pregnant women who are giving birth for the first time) and multiparous (women who have multiple children) may have different concerns, which may be associated with risk of antenatal depression. This study aims to examine the role of social support and stressful life events as risk factors for antenatal depression in nulliparous and multiparous women. The sample included 1,524 pregnant women recruited from an obstetrics setting at the end of the first trimester of pregnancy from two Spanish tertiary-care public hospitals. The sample completed the Patient Health Questionnaire (PHQ-9), and the "social support" and "stressful life events" subscales of the Postpartum Depression Predictor Inventory-Revised (PDPI-R). Nulliparous women reported a lower prevalence of depressive symptoms (15.6 percent) compared to multiparous mothers (20.1 percent). In both groups, marriage/partner problems (NP: ß = 0.178, p < .01 vs MP: ß = 0.164, p < .01) and a perceived lack of instrumental support from friends (NP: ß = -0.154, p < .01 vs MP: ß = -0.154, p < .01) were significant risk factors for antenatal depression. However, nulliparous women have more risk factors such as unemployment (ß = 0.096, p < .05), job change (ß = 0.127, p < .01), financial problems (ß = 0.145, p < .01) and lack of instrumental support from partner (ß = -0187, p < .01). For multiparous women, moving (ß = 0.080, p < .05) and lack of instrumental support from family (ß = -0.151, p < .01) were risk factors. These results suggest the critical need for screening and designing preventive interventions adapted and taking into consideration parity to provide more effective health care during pregnancy.

The healthy moms and babies app to prevent postpartum depression: analysis of user-profiles and dropout cases.

Introduction: Perinatal depression affects mothers, babies and society. Preventive interventions are needed, but face barriers to access. E-health interventions could be an effective and accessible option. To date, few studies have attempted to understand the use of mobile health (m-health) applications and why they are not more widely used. This study aims to understand the demographic characteristics of enrolled participants and examine dropout patterns through the Healthy Moms and Babies app. Methods: A longitudinal study was conducted with a sample of 511 women recruited between 2020 and 2022. Data were collected from the app, including sociodemographic information, the participant's progress through the modules of the app, and the permissions granted to use the app. Results: Out of the 511 women who completed the initial form to initiate participation, 279 downloaded the app and completed the evaluation. Results indicated that granting permission to be notified about the module's availability is related to an increase in the use of the first modules. Conclusion: This study shows the importance of establishing follow-ups in the use of mobile apps during the perinatal period.

Relationship between social support and perinatal depression during the COVID-19 pandemic.

AIMS/BACKGROUND: This research aimed to identify the sources of social support and its relationship with perinatal depression (PPD) during the coronavirus (COVID-19) pandemic. DESIGN/METHODS: We carried out a cross-sectional study with a sample of 3,356 women during perinatal period living in Spain. We used five items from the Spanish version of the Coronavirus Perinatal Experiences - Impact Survey to assess the impact of COVID-19 on social support and, the Edinburgh Postnatal Depression Scale was used to assess depressive symptomatology. RESULTS: The results obtained identified a possible relationship between seeking in-person support (OR = 0.51; 0.67, during pregnancy and after delivery respectively) and degree of feeling social support (OR = 0.77; 0.77) during the COVID-19 pandemic with a lower prevalence of depression. Otherwise, requiring the help of a mental health professional (OR = 2.92; 2.41) and weeks of confinement (OR = 1.03; 1.01) appeared to be associated with a higher prevalence of depression. During pregnancy, a possible association was found between the degree of concern about future changes in support and involvement of family and friends (OR = 1.75) with a higher prevalence of depression. On the other hand, in the postpartum period, there seems to be a relationship between seeking social support through social media (OR = 1.32) with a higher prevalence of depression and receiving support from friends (OR = 0.70) and health professionals (OR = 0.53) with a lower prevalence of depression. CONCLUSION: These results highlighted the importance of protecting perinatal mental health during the COVID-19 pandemic by protecting and developing social support networks.

The socio-demographic profile associated with perinatal depression during the COVID-19 era.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has caused an increase in perinatal depression. The aim of this research was to identify which sociodemographic variables are related to the increase in perinatal depression due to the pandemic. In addition to estimating to what extent they predict perinatal depression, differentiating the prenatal and postnatal periods. METHODS: The sample consisted of 3,356 subjects, 1,402 in the prenatal period and 1,954 in the postnatal period. The Edinburgh Postnatal Depression Scale was used to assess depressive symptomatology. A subset of 14 questions was included to collect demographic data. Items from the Spanish version of the Coronavirus Perinatal Experiences Survey were also included. RESULTS: Experiencing the change of environment due to COVID-19 as negative and having a history of mental health predict perinatal depression, otherwise having higher education decreases the risk. In the prenatal stage having symptoms compatible with COVID-19 is a predictor of perinatal depression and having more than 3 years living together with the partner and being a housewife decreases the risk. In the postnatal stage being unemployed is a predictor of prenatal depression and being a first-time mother decreases the risk. CONCLUSIONS: This study highlights the relevance of sociodemographic status. It is essential to be aware of the risk factors of perinatal depression, to make adequate prevention, and to create health policies to alleviate the consequences of the pandemic.

The impact of the war in Ukraine on the perinatal period: Perinatal mental health for refugee women (pmh-rw) protocol.

Background: The aim of the Perinatal Mental Health for Refugee Women (PMH-RW) Project is to investigate the impact of the war on perinatal mental health: anxiety, post-traumatic stress, depression, and birth trauma symptoms. It will also evaluate the factors that serve as protective elements for the development of these potential diagnoses (such as personality traits, social support, sociodemographic characteristics, and access to medical/mental health services). Method: An international observational cohort study with baseline data is being assessed in Ukraine (for internal refugees) and several European Countries (for external refugees). The study includes as participants both pregnant women and those who have recently given birth (with babies up to 1 year old). The assessment includes measures on depression (EPDS), anxiety (GAD-7), experiences during birth (City Birth Questionnaire), post-traumatic stress symptoms [Impact of events scale-revised (PTSD-R)], Personality (10-Item Personality Inventory-TIPI), and a questionnaire for socio-demographic data which also such social support. Conclusion: This study will provide needed information for determining the impact of the Ukrainian Crisis on perinatal mental health by studying potential risk and protective factors. The data collected will be used to inform policymakers with useful information that can be used in the development of plans to protect and promote the mental health of the perinatal refugees impacted by this event. Also, it is our hope that data collected from this study will serve to plant the seeds for further research regarding the impact of the crisis in Ukraine on the offspring and to analyze how these events are affecting further generations.

Effectiveness of interventions to prevent perinatal depression: An umbrella review of systematic reviews and meta-analysis.

BACKGROUND: To date, dozens of systematic reviews (SRs) and meta-analyses (MAs) summarize the effectiveness of preventive interventions for perinatal depression. However, the results are inconclusive, making an urgent need to step up to higher levels of evidence synthesis. AIMS: To summarize and compare the evidence from the SR&MA examining the effectiveness of all types of interventions for preventing perinatal depression. METHOD: PubMed, PsycINFO, Cochrane Database of Systematic Reviews and OpenGrey were searched from inception to December 2022. We selected SR&MA of randomized controlled trials (RCTs) that compared all types of preventive interventions for perinatal depression with control groups whose outcome was the reduction of depressive symptoms and/or incidence of new cases of perinatal depression (PROSPERO: CRD42020173125). RESULTS: A total of 19 SRs and MAs evaluated 152 unique RCTs that included 83,408 women from 26 countries and five continents. The median effect size for any intervention was SMD = 0.29 (95% CI: 0.20 to 0.38). Exercise/physical activity-based, psychological, and any type of intervention showed median effect sizes of 0.43, 0.28 and 0.36, respectively. The degree of overlap among RCTs was slight. According to AMSTAR-2, 79% of them were rated as low or critically low-quality. The strength of evidence, according to GRADE, was poorly reported and, in most cases, was low. CONCLUSIONS: Exercise/physical activity-based and psychological interventions have a small-to-medium effect on reducing perinatal depressive symptoms. There is insufficient evidence to conclude that dietary supplements and pharmacological interventions are effective in preventing perinatal depression. There is a need for high-quality SR&MA of RCTs, mainly focusing on universal preventive interventions.

Understanding Healthcare Professionals' Knowledge on Perinatal Depression among Women in a Tertiary Hospital in Ghana: A Qualitative Study.

Health conditions affecting women in the perinatal period still account for a major contribution to disease burden in Sub-Saharan Africa, yet there is a dearth of empirical research to understanding health professionals' perspective on their experiences and how they care for perinatal women in depression. We used a qualitative exploratory descriptive approach through a face- to face-interview to explore the knowledge of 11 health professionals of Komfo Anokye Teaching Hospital, Kumasi- Ghana. Interviews were taped recorded and transcribed verbatim. The study adopted Haase's modification of Colaizzi's method for the analysis. Four main themes emerged: ineffective communication (Referral lapses among care providers, long waiting time, lack of confidentiality), workload (Inefficient staff to meet perinatal women's need, no screening tools and time constraints), Reaction to patients symptoms (Identifying patient's symptoms, assessment through patient's centeredness and Education and counselling). Our results emerged that time constraints, stigmatization and lack of awareness delayed the care and management of perinatal depression among healthcare professionals in the hospital setting. There is the need to improve healthcare professionals' knowledge on perinatal depression and it is imperative for the hospital administrators to invest in continuous training and professional development for healthcare professionals.

Psychological, Psychosocial and Obstetric Differences between Spanish and Immigrant Mothers: Retrospective Observational Study.

This study analyzed the influence of psychological and psychosocial factors of pregnant women at an obstetric level. The possible differences between Spaniards and immigrants were studied. This was a retrospective observational study. The sample has been divided into two study cohorts, one consisting of Spanish pregnant women and one consisting of foreign pregnant women. Both completed the Revised Postpartum Depression Predictors Inventory and the Patient Health Questionnaire-9. A total of 15.9% of Spanish women and 23.2% of immigrants had depressive symptoms. Immigrants claim to have less support at the partner, family, and friendship levels than Spaniards. Moreover, 16.4% of Spaniards vs. 8.1% of immigrants had pregnancy complications; Cesarean section was performed in 16.2% of Spaniards vs. 7.9% of immigrants. A greater number of premature births were detected in immigrants than in Spaniards. Access to universal healthcare is a protective factor against socioeconomic and cultural conditions affecting the mental and obstetrical health of immigrants.

Clinical practice guidelines with recommendations for peripartum depression: A European systematic review.

OBJECTIVE: This study aims to systematically review all Clinical Practice Guidelines (CPGs) with recommendations for peripartum depression in European countries. METHODS: A systematic review according to the PRISMA statement was conducted. CPGs focussing on peripartum depression or with at least one specific recommendation for peripartum depression from European countries were selected. Searching was conducted in electronic databases (MEDLINE and PsycINFO), and by contacting professional societies and international experts until November 24th, 2021. Characteristics of the included CPGs and their recommendations were extracted. A methodological quality assessment was conducted using the AGREE-II tool. RESULTS: A total of 239 records were identified after duplicate removal. Of these, 54 were examined for full-text inspection. The final selection yielded 14 CPGs from 11 European countries in 10 languages. Of them, 11 provided recommendations on pharmacological treatments, 10 on psychological treatment (e.g., cognitive-behavioural therapy), 10 on screening, 8 on diagnosis, 6 on other treatments (e.g., physical exercise), 5 on prevention, and 5 other recommendations (e.g., provide information). Regarding the overall methodological quality, only five (35.7%) guidelines were rated as of adequate quality, reaching a score ≥ 70% in the overall assessment of the AGREE-II instrument. Of the six AGREE-II domains, applicability scored the lowest and clarity of presentation scored the highest. CONCLUSION: The absence of CPGs in most European countries, the discrepancy in recommendations and the low methodological quality of the guidelines may lead to disparities and inequalities in peripartum depression management in Europe. The COST Action Riseup-PPD highlights key considerations for future guideline developers.

Review of suicidal ideation during pregnancy: risk factors, prevalence, assessment instruments and consequences.

BACKGROUND: Pregnancy is a period when women are particularly vulnerable to suicidal ideation and a great opportunity for suicide risk prevention. AIMS: This study aimed to establish a comprehensive understanding of suicidal ideation prevalence, risk factors, screening tools, consequences and management during pregnancy. METHOD: A literature search was performed in MEDLINE and PsycInfo databases from 2016 to 2021. A narrative synthesis of the literature and a critical overview of the current issues/questions to be addressed within the topic of suicidal ideation during pregnancy was performed. RESULTS: The prevalence of suicidal ideation during pregnancy was between 2.73 and 18% internationally. The risk factors identified were major depressive disorder, anxiety disorder, difficulties with sleep, previous suicide attempts, high rumination, low incomes, being black, being young, low educational level, partner violence, having poor support, food insecurity, history of child abuse, high obstetric risk, multiparity, previous induced abortion and exposure to tobacco or human immunodeficiency virus diagnosis. The screening tools used for suicidal ideation during pregnancy were item 10 of the Edinburgh Postpartum Depression Scale and item 9 of the Patient Health Questionnaire. Results showed that suicidal ideation during pregnancy is associated with poor cognitive development in children and low birth weight. No case management studies on suicidal ideation were found. LIMITATIONS: The main limitation of the available studies was the lack of articles with a high degree of methodological rigour on this subject. CONCLUSIONS: This narrative review is a state-of-the-art paper about suicidal ideation during pregnancy. Further research is needed, and researchers should carry out systematic reviews and meta-analyses, leading to Clinical Practice Guidelines in this area. This effort would improve our evidence-based practice in Perinatal Psychology and prevent associated suicidal behaviour.

The Impact of the COVID-19 Pandemic on Perinatal Depression and Anxiety: A Large Cross-sectional Study in Spain.

BACKGROUND: The current COVID-19 pandemic is a unique stressor with potentially negative consequences for pregnant and postpartum women. We investigated the impact of the COVID-19 pandemic on perinatal depression and anxiety in Spain. METHOD: This cross-sectional study was conducted from June to December 2020. A total of 3,356 adult pregnant and postpartum women (with infants up to 6 months of age) from all Spanish regions were surveyed. The assessment included measures of Coronavirus Perinatal Experiences (COPE-IS questionnaire) and Generalized Anxiety Disorder Screener (GAD-7=10) and Edinburgh Postnatal Depression Scale (EPDS=10). RESULTS: The prevalence of perinatal anxiety and depression (above established cut-offs) was 33.3% and 47.2%, respectively; 29.2% of women screened positive for both conditions. Higher rates of perinatal depression and anxiety were associated with increased concern about threats of COVID-19, especially employment and the financial impact, along with increased overall levels of distress. Exposure to COVID-19 and its symptoms did not appear to be a relevant risk factor. More COVID-19-related predictors and a higher rate of depression were found in postpartum women. CONCLUSIONS: The current study highlights the substantial increase in symptoms of perinatal depression and anxiety, especially in postpartum women. Interventions for perinatal mental health should be a priority.

Suicidal ideation: Prevalence and risk factors during pregnancy.

INTRODUCTION: Although suicide is the main cause of maternal death during pregnancy in industrialized countries, there are few research regarding the prevalence and risk factors of suicidal ideation during pregnancy, especially in Spain. METHOD: In a multicenter study, the sample included 1,524 pregnant women recruited from an obstetrics setting from two Spanish tertiary-care public hospitals. The prevalence of prenatal suicidal ideation was estimated by analyzing their responses to item 9 on the Patient Health Questionnaire (PHQ-9). The risk factors (which increases the probability of having suicidal ideation) included sociodemographic and biomedical variables, and the stress subscale from the revised prenatal version of the Postpartum Depression Predictors Inventory (PDPI-R). RESULTS: A total of 2.6% of pregnant women reported suicidal ideation. Risk factors of suicidal ideation during pregnancy include sociodemographic, such as prior history of depression (ß = 0.120, p < .05), unemployment (ß = 0.149, p < .05), and being an immigrant (ß = 0.140, p < .01), and biomedical variables, such as previous abortion (ß =0.169, p < .01) and assisted reproduction (ß = -0.100, p < .05). DISCUSSION: Given that the prevalence of suicidal ideation is higher than expected, the results of the study suggest the critical need for screening and designing preventive interventions adapted to pregnant women to decrease risk of associated suicidal behavior. In protocols carried out by midwives, specific risk factors should be included in health screenings during pregnancy.

αN-Acetyl ß-Endorphin Is an Endogenous Ligand of σ1Rs That Regulates Mu-Opioid Receptor Signaling by Exchanging G Proteins for σ2Rs in σ1R Oligomers.

The opioid peptide ß-endorphin coexists in the pituitary and brain in its αN-acetylated form, which does not bind to opioid receptors. We now report that these neuropeptides exhibited opposite effects in in vivo paradigms, in which ligands of the sigma type 1 receptor (σ1R) displayed positive effects. Thus, αN-acetyl ß-Endorphin reduced vascular infarct caused by permanent unilateral middle cerebral artery occlusion and diminished the incidence of N-methyl-D-aspartate acid-promoted convulsive syndrome and mechanical allodynia caused by unilateral chronic constriction of the sciatic nerve. Moreover, αN-acetyl ß-Endorphin reduced the analgesia of morphine, ß-Endorphin and clonidine but enhanced that of DAMGO. All these effects were counteracted by ß-Endorphin and absent in σ1R-/- mice. We observed that σ1Rs negatively regulate mu-opioid receptor (MOR)-mediated morphine analgesia by binding and sequestering G proteins. In this scenario, ß-Endorphin promoted the exchange of σ2Rs by G proteins at σ1R oligomers and increased the regulation of G proteins by MORs. The opposite was observed for the αN-acetyl derivative, as σ1R oligomerization decreased and σ2R binding was favored, which displaced G proteins; thus, MOR-regulated transduction was reduced. Our findings suggest that the pharmacological ß-Endorphin-specific epsilon receptor is a σ1R-regulated MOR and that ß-Endorphin and αN-acetyl ß-Endorphin are endogenous ligands of σ1R.

Healthy Moms and Babies Preventive Psychological Intervention Application: A Study Protocol.

Depression is the most common psychological disorder during the perinatal period, and its negative effects extend to mothers, babies, their family and society. Scientific evidence points to the urgency of designing preventive interventions and concludes that the gestational period is the most appropriate time to implement these interventions. However, many pregnant women do not seek professional help due to a lack of knowledge about the importance of mental health, its impact, and the available intervention options, as well as a lack of time and financial resources. E-health interventions can be an efficient, cost-effective, and accessible resource for preventing postpartum depression that can circumvent the barriers that pregnant women face. This randomized clinical trial will examine the efficacy of Healthy Moms and Babies, an app aimed at preventing postpartum depressive symptomatology. The second objective of this study is to analyze the effectiveness of the tool in preventing anxious symptomatology. The primary outcome measure is the difference in the mean score between the intervention and control groups on the Patient Health Questionnaire-9 (PHQ-9) at the end of the intervention and at 3 and 6 months postpartum. The secondary outcome will be determined by using the Generalized Anxiety Disorder Screener (GAD-7) at the same time points. The research findings can be used to determine pregnant women's use of the e-health application for the prevention of postpartum depression, whether the Healthy Moms and Babies intervention app is an effective and useful resource, and what modifications will need to be made to the tool in future updates.
