Objectives: Pregnant women represent a population category at high risk of severe rubella infection, capable of adversely affecting their fetus. This study was conducted to determine the seroprevalence of anti-rubella antibodies in pregnant women seen in prenatal consultations at the Sino-Gabonese Friendship Hospital in Franceville Patients and Methods: A prospective, cross-sectional study was conducted at the Sino-Gabonese Friendship Hospital in Franceville, from April 3 to July 27, 2023. Using a structured and pre-established questionnaire, sociodemographic and obstetrical characteristics were obtained... Three milliliters of blood were collected from participants to measure rubella-specific IgG antibody levels using the OnSite Rapid Test Rubella IgG/IgM COMBO lateral flow immunochromatographic assay. Results were considered significant at p≤0.05. Results: The study included 107 pregnant women seen in prenatal consultations. With a mean age of 27.9±7.1 years, anti-Rubella IgG antibodies were found in 87 pregnant women, indicating an overall seroprevalence of 81.30% (95% CI: [0.72 - 0.87). Of these, 6.9% (n = 6) of the women were serum anti-Rubivirus IgM carriers. In univariate analysis, it was indicated that pregnant women in the study aged between 21-30 years (OR =0.33; 95% CI: [0.12-0.9] p=0.0027), student (OR =6.35; 95% CI: [1.39-29.09] p=0.001), or without professional status (OR =0.05; 95% CI: [0.01- 0.27] p<0.001), high school education (OR =8.24; 95% CI: [2.83-23.96] p<0.001), single (OR =0.3; 95% CI: [0.11-0.85] p=0.0021) or cohabiting OR =3.91; 95% CI: [1.21-12.64] p=0.0017) Residing in an urban area (OR =49; 95% CI: [1.43-16.75] p=0.006), in the first trimester of their pregnancy (OR = 0.29; 95% CI: [0.09-0.94] p= 0.033), with a history of spontaneous abortion (OR = 0.09; 95% CI: [1.04; 11.30] p= 0. 037), and unvaccinated (OR = 0.13; 95% CI: [0.05; 0.13] p<0.000), had an elevated risk of Rubella, After adjusting for risk factors by logistic regression, residence in a rural area (ORA = 139.87 95% CI : [1.74 -11236.216] p=0.027),and no vaccination (ORA = 43.3 95% CI: [1.13 -1662.7] p= 0.043), were identified as the only significant risk factors for Rubella for the present study population Conclusion: The high rate of susceptibility to rubella among pregnant women in the present study indicates that any short-term vaccination strategy aimed at reducing the number of susceptible women of childbearing age is imperative

This study uses explainable artificial intelligence to analyze major predictors of poor self-rated health, dementia and their comorbidity, which include various aspects of social support. Data came from the Korean Longitudinal Study of Ageing (2016-2018), with 5527 participants aged 56 or more. The dependent variables were: (1) poor self-rated health (SRH) with 5 categories (very good, good, middle, poor, very poor); (2) dementia (no, yes); and (3) their comorbidity with 4 categories (SRH very good, good or middle, dementia no; SRH very good, good or middle, dementia yes; SRH poor or very poor, dementia no; SRH poor or very poor, dementia yes). The 49 demographic, socioeconomic and health-related predictors were included. The accuracy and area under the receiver operating characteristic curve (AUC) were compared for logistic regression and the random forest. Logistic regression and the random forest registered similar AUCs with the range of 0.80-0.87. Based on random forest variable importance, 18 out of top-20 predictors were identical for SRH, dementia and their comorbidity: previous SRH, life satisfaction - health, age, body mass index, income, chronic diseases, life satisfaction - economic, life satisfaction - overall, grandchildren alive, friendship meeting, brothers/sisters alive, class identity, children alive, social activity - friendship, education, children in weekly contact, religion and drinker. However, some variations were found among the three dependent variables, i.e., previous SRH for comorbidity (1st) and SRH (1st) compared to dementia (11th), grandchildren alive for SRH (6th) and dementia (4th) compared to comorbidity (9th), chronic diseases for comorbidity (6th) compared to SRH (10th) and dementia (10th). In terms of Shapley Additive Explanation (SHAP) values, the probability of dementia is expected to decrease by 5.57% in case a predictor grandchildren alive is included to the model. This study highlights the importance of social support for the prediction of poor self-rated health, dementia and their comorbidity. Specifically, the promotion of family support and friendship activity for elders would be vital for the prevention and management of their self-rated health and dementia.

Background and Objective: Intimate relationships hold significant importance during emerging adulthood. This study aimed to investigate the critical determinants of perceived well-being in friendship relationships during emerging adulthood.Method: Using a quantitative approach, a sample of 726 undergraduate students from the Ferdowsi University of Mashhad were selected through convenience sampling. They completed the Interpersonal Behaviors Questionnaire (IBQ), the Compassionate and self-image goals scale (CSIGS), the Basic Need Satisfaction in Relationships Scale (BNS-RS), the Interpersonal Needs Questionnaire (INQ-10), Friendship Self-Regulation Questionnaire (SRQ-F), Interpersonal Behaviors Questionnaire-Self (IBQ-self), State Level Subjective Vitality Scale (SVS-SL), the Perceived Relationship Quality Component (PRQC), and the Basic Empathy Scale (BES). Data analysis was conducted using Partial Least Squares Structural Equation Modeling (PLS-SEM).Results: The results indicated that the critical determinants in predicting perceived well-being in friendship relationships were, in order, goals in friendship relationships, friendship self-regulation, perceived support of basic psychological needs by friends, satisfied basic psychological needs, frustrated psychological needs, and supporting the basic psychological needs of friends.Conclusion: The findings demonstrate that self-determination theory (SDT) provides a coherent framework for explaining perceived well-being in friendships.
