Article Synopsis
  • Pregnancy involves significant hormonal and metabolic changes to support fetal development, which the study investigates through changes in the salivary microbiome and biochemical markers between the second and third trimesters.
  • Saliva samples from 45 pregnant women were analyzed using advanced DNA sequencing techniques, revealing notable shifts in microbial diversity, including a 3-fold increase in Bacteroidota and changes in other microbial taxa.
  • Biochemical changes included increased BMI, pulse rate, glucose, and cholesterol levels in the third trimester, along with correlations between these factors and microbial abundance, emphasizing the need for monitoring oral health and metabolic health during pregnancy.

Background: The placenta acts as a buffer to regulate the degree of fetal exposure to maternal cortisol through the 11-Beta Hydroxysteroid Dehydrogenase isoenzyme type 2 (11-β HSD2) enzyme. We conducted a systematic review and meta-analysis to assess the effect of prenatal psychological distress (PPD) on placental 11-β HSD2 gene expression and explore the related mechanistic pathways involved in fetal neurodevelopment.

Methods: We searched PubMed, Embase, Scopus, APA PsycInfo®, and ProQuest Dissertations for observational studies assessing the association between PPD and 11-β HSD2 expression in human placentas.

Biobanks facilitate genome-wide association studies (GWASs), which have mapped genomic loci across a range of human diseases and traits. However, most biobanks are primarily composed of individuals of European ancestry. We introduce the Global Biobank Meta-analysis Initiative (GBMI)-a collaborative network of 23 biobanks from 4 continents representing more than 2.

Qatar Biobank (QBB) is actively acquiring data on the range of short- and long-term health impacts associated with COVID-19. This is performed through the COVID-19 biorepository National project. In this report, we describe the most common indications for the referral to Qatar's healthcare system of COVID-19 biorepository participants in comparison with the Qatar Biobank (QBB) general population study.

Biobank science is progressively becoming indispensable for the development of novel diagnostic tools in health care, by pairing standardized high-quality biological samples, phenotypic, and omics data required to best characterize the underlying biological mechanisms of response to therapy and survival. Qatar Biobank (QBB), Qatar's National Repository Centre for biological samples and health information, aligning with these endeavors, has developed a strategic framework to enable biobanking science that can be transformed into tangible health care diagnostic tools. In this concept, QBB works closely with multidisciplinary stakeholders: (1) governmental authorities ( = 2), (2) health providers ( = 3), (3) academic institutions ( = 28), (4) other research institutions ( = 6), and (5) the Qatar National Research Fund, by providing data and biospecimens to research projects.
