All 10 self-ratings loaded on one factor with high internal reliability. Method: In all 506 adult participants, completed short measures of the bright side, Big Five traits (TIPI) and a short measure of the dark side, personality disorders (PID-5-BF). Results: Correlations and regressions suggested that wellness was related to sex, education and religious beliefs as well as four of five bright- and dark-side traits. Being Sanguine was most positively, and Choleric most negatively, associated with subjective wellness. Detachment and Negative Affect were the highest dark-side correlates. The final regression suggested that over a third of the variance in subjective wellness could be explained by four bright- and two dark-side factors. Conclusions: Personality factors, especially instability and negative affectivity, play a crucial role in all aspects of wellness. Implications and limitations are acknowledged.展开更多

Depending on their type, location and size, malformations can cause functional, psychological and aesthetic defects. The aim of this study is to document the frequency of congenital malformations, describe the characteristics of malformed newborns and their biological mothers, and identify the different types of malformations presented by newborns at the INSE. Methods: Descriptive cross-sectional study of clinically visible malformed newborns. It was carried out from January 1, 2021 to January 1, 2022 at the INSE neonatology unit. Epi info version 3.1 software was used for data entry and analysis. Results: Of a total of 2332 neonates hospitalized during the study period, 81 (3.5%) cases had at least one clinically visible congenital malformation. Nearly 84% had an age ≤ 7 days at the time of admission. The male sex was most concerned (60.5%). Newborns referred by a health facility accounted for 84%. Malformations of the digestive system accounted for 30.9% of cases, followed by those of the limbs (19.8%) and poly malformative syndrome (19.8%). Conclusion: This study shows that congenital malformations exist and are frequent in Guinea. Our results could therefore be the starting point for the future establishment of a national register of congenital malformations.展开更多
