Inflammatory biomarkers and perinatal depression: a systematic review

This article is a preprint and has not been peer-reviewed [what does this mean?]. It reports new medical research that has yet to be evaluated and so should not be used to guide clinical practice.Background: Approximately 10 to 20% of pregnant women worldwide experience perinatal depression (PND), a depressive episode with onset during pregnancy or after childbirth. We performed a systematic review to identify, summarize and discuss studies on inflammatory biomarkers described in relation to PND. Methods: Inclusion criteria defined the selection of observational studies written in English, French, Spanish or Portuguese, that evaluate analytical levels of inflammatory molecules (protein levels) in biological fluids in women, with a diagnosis of depression using ICD/DSM diagnostic criteria or depressive symptoms assessed by standardized psychometric instruments, during pregnancy and/or postpartum. Case reports, experimental studies, reviews, qualitative analysis, meta-analysis, gray literature or replicated data were excluded. Three electronic databases were used for search (Pubmed, Web of Science and PsychInfo) and quality assessment of selected studies were performed using the Newcastle-Ottawa Scale. Data extraction included study design; number of subjects; obstetric information; tools and timepoints of depression and inflammatory markers assessment. Results: 56 studies where the major aim was to analyze the association between depression and inflammatory biomarkers during pregnancy and postpartum period were included in this systematic review. Overall, the findings of our systematic review lend support to the hypothesis that several inflammatory markers may be associated with peripartum depressive symptoms. The associations were somewhat different looking at pregnancy compared to the delivery time-point and postpartum, and mainly referred to increased levels of IL-6, IL-8, CRP and TNF-α among depressed. Discussion: Our results revealed high heterogeneity in relation to the timing of biological sampling for markers, as well as timing and instruments used for depression assessment within the perinatal period for the different studies. Studies differed also in relation to use of biomarkers or depression as exposure and outcome respectively, and whether these were addressed at the same timepoint or separate ones. Given the high burden of PND on women, children and families, it is crucial to try to harmonize methods used in related studies, in order to be able to pool results that could give us insights into the pathophysiological mechanisms behind how the immune system and PND are connected; this could have great impact on early detection, prevention and even treatment of PND.AS-F was supported by the Portuguese Foundation for Science and Technology and the Portuguese Ministry of Science, Technology and Higher Education, through the national funds, within the scope of the Transitory Disposition of the Decree No. 57/2016, of 29th of August, amended by Law No. 57/2017 of 19 July and previously through the fellowship grant SFRH/BPD/107732/2015.

Spanish validation and factor structure of the birth satisfaction scale-revised (BSS-R).

Objective: To translate and validate a Spanish-language version of the Birth Satisfaction Scale-Revised (BSS-R) and describe key measurement properties.Design: A cross-sectional instrument validation design examining factor structure, validity and reliability.Setting: Three public hospital sites in Spain. Participants: 202 women who had given birth within the past four weeks provided complete questionnaire data for analysis. Measurements and findings: Measures included the Spanish version of the BSS-R (S-BSS-R) and the Perceived Stress Scale (PSS). The tri-dimensional measurement model of the BSS-R was found to offer a good fit to Spanish data. Known-groups discriminant validity was found to be excellent with women experiencing a non-intervention delivery having higher S-BSS-R scores (

Shortened Version of the Token Test: Normative data for Spanish-speaking pediatric population

OBJECTIVE: To generate normative data for the Shortened Version of the Token Test in Spanish-speaking pediatric populations. METHOD: The sample consisted of 4,373 healthy children from nine countries in Latin America (Chile, Cuba, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Puerto Rico) and Spain. Each participant was administered the Shortened Version of the Token Test as part of a larger neuropsychological battery. Shortened Version of the Token Test total scores were normed using multiple linear regressions and standard deviations of residual values. Age, age2, sex, and mean level of parental education (MLPE) were included as predictors in the analyses. RESULTS: The final multiple linear regression models showed main effects for age in all countries, such that score increased linearly as a function of age. In addition, age2 had a significant effect in all countries, except Guatemala and Puerto Rico. Models showed that children whose parent(s) had a MLPE >12 years obtained higher score compared to children whose parents had a MLPE ≤12 years in Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, Puerto Rico, and Spain. The child’s sex did not have an effect in the Shortened Version of the Token Test total score for any of the countries. CONCLUSIONS: This is the largest Spanish-speaking pediatric normative study in the world, and it will allow neuropsychologists from these countries to have a more accurate interpretation of the Shortened Version of the Token Test when used in pediatric populations

CIBERER : Spanish national network for research on rare diseases: A highly productive collaborative initiative

Altres ajuts: Instituto de Salud Carlos III (ISCIII); Ministerio de Ciencia e Innovación.CIBER (Center for Biomedical Network Research; Centro de Investigación Biomédica En Red) is a public national consortium created in 2006 under the umbrella of the Spanish National Institute of Health Carlos III (ISCIII). This innovative research structure comprises 11 different specific areas dedicated to the main public health priorities in the National Health System. CIBERER, the thematic area of CIBER focused on rare diseases (RDs) currently consists of 75 research groups belonging to universities, research centers, and hospitals of the entire country. CIBERER's mission is to be a center prioritizing and favoring collaboration and cooperation between biomedical and clinical research groups, with special emphasis on the aspects of genetic, molecular, biochemical, and cellular research of RDs. This research is the basis for providing new tools for the diagnosis and therapy of low-prevalence diseases, in line with the International Rare Diseases Research Consortium (IRDiRC) objectives, thus favoring translational research between the scientific environment of the laboratory and the clinical setting of health centers. In this article, we intend to review CIBERER's 15-year journey and summarize the main results obtained in terms of internationalization, scientific production, contributions toward the discovery of new therapies and novel genes associated to diseases, cooperation with patients' associations and many other topics related to RD research

Increasing opportunities for networking and public engagement through SRIP Research Development Workshop Grants

The Society for Reproductive and Infant Psychology (SRIP) is committed to supporting the development of research. For this purpose, the SRIP offers funding to support development activities, such as hosting a workshop to bring together collaborators to develop a future project proposal, an event aimed at disseminating research findings, a meeting to plan research impact with non-academic stakeholders, or even a research-led training event to support evidence-based practice (Lafarge, 2021). Such funding can support costs incurred from venue hire, travel and accommodation for speakers and delegates, and other incidental costs. Costs from online hosting can also be sought, for remote or online activities. This editorial aims to highlight the range of activities supported by these grants, including the utility for promoting public involvement and engagement in research

Influence of Maternal Stress during Pregnancy on Child’s Neurodevelopment

(1) Background: High stress levels during pregnancy can affect the organogenesis and the foetus’ central nervous system maturation. The objective of this study was to determine whether a relationship between maternal stress during pregnancy and alterations in child neurodevelopment exists; (2) Methods: A bibliographical review was carried out following PRISMA Methodology and using Scopus, Web of Science and Cinahl databases. The research questions were made using PEO methodology (Participants, Exposition, Outcomes). Moreover, article quality was measured using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies; (3) Results: 22 articles that fit the inclusion criteria were selected. Different elements altered because of maternal stress during pregnancy could side with alterations in different areas of the neurodevelopment, such as cognitive development, motor development, behaviour, temperament, memory and learning abilities; (4) Conclusions: Although maternal stress can have an influence on children’s neurodevelopment, it is still unknown which are the specific elements related to this stress that can modify it negatively. Furthermore, future studies should evaluate whether a sex-specific association exists
