Expecting a child conceived by medically assisted reproduction in the context of infertility: A qualitative case study of the experience of pregnant women and their partners
No full textBackground: Infertility affects around one in six people worldwide. Technological advances and changes in legislation in medically assisted reproduction (MAR) are helping more people achieve parenthood after a journey marked by infertility. Yet the unique experience of women who become pregnant after MAR, and of their partners, remains little known. Aim: To describe the experience of pregnant women and their partners during a pregnancy resulting from infertility-related MAR by examining their emotions throughout the pregnancy, their parental identity construction, and transformations experienced in various spheres of their life. Methods: We conducted an integrated case study using a descriptive qualitative approach. Semi-structured interviews were conducted with 21 participants from Quebec (Canada), including 13 pregnant women and eight partners (five men, three women) who had conceived by infertility-related MAR. The data were analysed abductively. Findings: The pregnant women and their partners experienced intense emotions throughout the pregnancy, oscillating between joy, fear, and relief. Parental identity construction was marked by expectation, hope, and a transition centred on pregnancy and infertility. They also transformed their relationships, adapting as a couple, redefining family and social ties, and entering a new normal with healthcare professionals. Conclusion: For pregnant women and their partners, pregnancy after infertility-related MAR is fraught with paradoxical emotions and marked by challenging parental identity construction. Social and family recognition of their journey influences how they navigate the transitional period of pregnancy and project themselves into their parental role. Personalised, empathetic support from healthcare professionals is essential to support them during pregnancy and facilitate their transition to parenthood
Converging evidence of a specific vulnerability of young boys to parental childhood trauma
No full textAbstract
Objective
Childhood trauma is common among parents and can have intergenerational effects. Preliminary evidence suggests that young boys may be more vulnerable to maternal childhood trauma than girls. This finding needs to be replicated, and it remains to be determined whether it also applies to paternal childhood trauma. The current study aims to examine the associations between parental childhood trauma and 3 indicators of early functioning (general development, socioemotional development, and temperament) in offspring and to assess the moderating role of child sex.
Method
Childhood trauma was assessed during pregnancy in 3 community samples of women (N = 143; N = 195; N = 216) and postnatally in 1 community sample of fathers (N = 165). Child functioning was assessed using parental reports of child development and temperament between 6 and 38 months postnatal. Regression-based moderation analyses were conducted.
Results
Significant associations between parental childhood trauma and adverse child outcomes were observed in all samples. A moderating role of child sex was supported in 3 of the 4 samples, all indicating greater vulnerability to parental childhood trauma among boys.
Conclusion
These findings suggest that maternal and paternal childhood trauma are associated with poorer functioning in infants and toddlers, but only in boys. This has implications for personalized preventive interventions with parents exposed to childhood trauma. These results call for replication with large and diverse samples including biological measures and observational measures of child development

Integration of Water Management Into the Energy Management Strategy for a Fuel Cell Vehicle
No full textUnlike other studies that focus solely on determining the optimal power distribution for a fuel cell hybrid electric vehicle (FC-HEV), this article aims to integrate water management into the energy management strategy (EMS) by designing an adaptive efficient purge strategy. This article investigates the impact of integrated water management into the EMS (IWM-EMS) on the performance and operating cost of FC-HEV. The IWM-EMS consists of two levels: the first level is the EMS, which determines the optimal power, and the second level is the proposed purge strategy. The proposed IWM-EMS in this article is the adaptive IWM-EMS (AIWM-EMS), which utilizes an adaptive efficient purge strategy that can adjust based on the fuel cell (FC) reference current. Another IWM-EMS is the nonadaptive IWM-EMS (NAIWM-EMS), which utilizes a constant purge strategy suggested by the FC manufacturer for all current levels. The results show that the FC-HEV under AIWM-EMS consumes 4.09% less hydrogen than the NAIWM-EMS and reduces total operating cost by up to 5.21%. In addition, 78.36% of the FCs’ operating time is spent in the high-efficiency zone
