Major Depressive Disorder (MDD) is the leading cause of disability worldwide. Genetic factors influence the effect of its main treatment option, antidepressant drugs (ATD). The GRIK4 rs1954787(T>C) genetic polymorphism was associated with response following 1–3 months of ATD treatment in some studies, but not others. We aimed to analyze its association with clinical outcomes in a cohort of 6-month ATD-treated patients and meta-analysis. Clinical data were obtained at baseline and after 1 (M1), 3 (M3), and 6 (M6) months of ATD treatment in 390 patients of the METADAP cohort. Mixed-effects models were used to assess the association of the GRIK4 rs1954787 polymorphism with the Hamilton Depression Rating Scale (HDRS) score and response and remission rates across time. Meta-analyses of ATD treatment response were performed with previously meta-analyzed data and METADAP. Compared to C allele carriers at M3 (n = 200), TT homozygotes at M3 (n = 66) had higher HDRS scores (coef = 3.37, 95% CI [1.30–5.54], P_adj = 0.0046) and lower remission rates (OR = 0.36, 95% CI [0.16–0.76], P_adj = 0.029). At M6, greater differences between TT homozygotes (n = 53) and C allele carriers (n = 152) were observed for HDRS scores (coef = 4.68, 95% CI [2.17–7.18], P_adj = 0.00091) and remission rates (OR = 0.26, 95% CI [0.12–0.54], P_adj = 0.0016). Meta-analyses of response were significant when comparing C vs T alleles (OR = 1.31, 95% CI [1.06–1.62], P = 0.014) and CC vs TT genotypes (OR = 1.63, 95% CI [1.10–2.38], P = 0.019). Altogether, our results support an association of the GRIK4 rs1954787(T>C) polymorphism with clinical improvement following ATD treatment. This association should be further assessed in other longitudinal studies. Its position within the glutamatergic system may help in understanding the mechanism of ATD action.

Background: Habenula, a hub brain region controlling monoaminergic brain center, has been implicated in major depressive disorder (MDD) and as a possible target of antidepressant response. Nevertheless, the effect of antidepressant drug treatment on habenular volumes remains unknown. The objective of the present research was to study habenular volume change after antidepressant treatment in patients with MDD, and assess whether it is associated with clinical improvement.Methods: Fifty patients with a current major depressive episode (MDE) in the context of MDD, and antidepressant‐free for at least 1 month, were assessed for habenula volume (3T MRI with manual segmentation) before and after a 3 months sequence of venlafaxine antidepressant treatment.Results: A 2.3% significant increase in total habenular volume (absolute volume: P = 0.0013; relative volume: P = 0.0055) and a 3.3% significant increase in left habenular volume (absolute volume: P = 0.00080; relative volume: P = 0.0028) were observed. A significant greater variation was observed in male patients (4.8%) compared to female patients. No association was observed between habenular volume changes and response and remission. Some habenula volume changes were associated with improvement of olfactory pleasantness.Conclusion: Habenular volumes increased after 3 months of venlafaxine treatment in depressed patients. Further studies should assess whether cell proliferation and density or dendritic structure variations are implied in these volume changes.

No increased risk of postpartum major depression (PPMD) was reported in women conceiving through assisted reproductive technologies (ART). However, ART may be associated with a higher risk of parenting difficulties in women with PPMD. In 359 women with a PPMD admitted to a Mother-Baby Unit (MBU), ART-women (4.2%) showed a 5-fold higher rate of parenting difficulties than those with spontaneous pregnancy (73.33% vs. 35.17%, multivariate ORa = 5.09 [1.48–17.48] p = 0.01). Specific support for mother-child relationship should be implemented in ART-women with PPMD.

The pathway to parenthood constitutes a fundamental and transformative stage in every individual’s life. While postpartum depression in mothers has been increasingly studied and acknowledged, paternal postpartum depression (PPD) has garnered only moderate research attention. This study aims to delve into the comprehension and knowledge of healthcare professionals who may encounter men suffering from postpartum depression. Within the framework of this qualitative research, we conducted six semi-structured interviews with various healthcare professionals. The data were subjected to interpretative phenomenological analysis, revealing the following themes: (1) the professionals’ uncertainty in the face of paternal PPD; (2) the context and timing of healthcare professionals’ involvement appeared unsuited for detecting paternal PPD; (3) the experiences of fathers were found not to be shared with healthcare professionals due to their inhibitions and avoidance reactions; (4) the social representation of the role of fathers influenced professionals in their considerations of this aspect. Strengthening the training and confidence of healthcare professionals in France would lead to an enhancement in the screening and management of paternal PPD. Additionally, the healthcare system should better organize postnatal support to enable caregivers to be more available during the peak of depression occurrence.

Introduction: Depression is one of the most common co‐morbidities during pregnancy; with severe symptoms, antidepressants are sometimes recommended. Social determinants are often linked with antidepressant use in the general population, and it is not known if this is the case for pregnant populations. Our objective was to determine if social determinants are associated with prenatal antidepressant intake via a systematic review and meta‐analysis.Methods: A systematic search of five databases was conducted to identify publications from inception to October 2022 that reported associations with prenatal antidepressant intake (use/continuation) and one or more social determinants: education, race, immigration status, relationship, income, or employment. Eligible studies were included in random effects meta‐analyses.Results: A total of 23 articles describing 22 studies were included. Education was significantly and positively associated with prenatal antidepressant continuation and heterogeneity was moderate. (Odds ratio = 0.83; 95% CI, 0.78 to 0.89; p < 0.00001; I² = 53%). Meta‐analyses of antidepressant use and education, race, and relationship status, and antidepressant continuation and income were not significant with high levels of heterogeneity.Discussion: While most social determinants in this review were not linked with prenatal antidepressant intake, lower maternal education level does seem to be associated with lower rates of prenatal antidepressant continuation.Conclusions: Education appears to be linked with prenatal antidepressant intake. The low number of included studies precludes conclusive evidence for other social determinants.

The COVID-19 pandemic had a major impact on mental health across populations, especially young and precarious people. Furthermore, COVID-19 diagnosis itself has been associated with psychiatric symptoms. However, only a few studies have assessed the mental health of precarious youth, and examined a possible association with food insecurity, while including COVID-19 diagnosis in their analyses. We aimed to determine the prevalence of poor mental health in precarious youth during the COVID-19 pandemic, and to investigate its possible association with food insecurity, independently of COVID-19 diagnosis. In a cross-sectional study conducted in the context of an employment program for precarious youth (18–25 years) living in Paris, France, 823 individuals were assessed for depression, anxiety, subjective distress and food insecurity during the second lockdown of 2020. A directed acyclic graph (DAG)-based approach was used to identify confounders for inclusion in a multivariate regression model. Of the 823 precarious youth, 45.93% reported significant symptoms of depression, 36.69% anxiety, 39% distress and 25.39% suicidal ideation. In the multivariate analysis based on DAG, food insecurity (less than one meal per day) was associated with depression (OR = 2.30; CI%: 1.19–4.51), anxiety (OR = 2.51; CI%: 1.29–4.88), distress (OR = 2.36; CI%: 1.23–4.57) and suicidal ideation (OR = 4.81; CI%: 2.46–9.44), independently of age, gender, education, COVID-19 contact and COVID-19 diagnosis. This study highlights the importance of food insecurity on mental health among young precarious people during the COVID-19 pandemic. Reducing food insecurity is essential to help reduce psychological distress.

The increasing prevalence of sexual abuse calls for exceptional awareness of its multidimensional impact on the mental, sexual, and social wellbeing of male adults. This study aims to deepen the overall understanding of sexual abuse consequences; to highlight some common resilience factors; and to strengthen therapeutic and social support. In this qualitative research, we conducted seven semi-structured interviews with male victims of sexual violence. The data were analysed with the interpretative phenomenological analysis. They shed light on the great suffering linked to sexual violence, and on seven themes which are seemingly pillars of resilience: bond to others, bond to the body, making sense of things, expression, rediscovering oneself, institutions, and finally, learning and commitment. The exploration of these themes reveals several avenues for adjusting care, most of which imply the importance of raising awareness so that spaces receiving the victims’ word can emerge.
