Sex Differences in Re-experiencing Symptoms Between Husbands and Wives Who Lost Their Only Child in China: A Resting-State Functional Connectivity Study of Hippocampal Subfields.

ABSTRACT: Background: Losing one's only child may lead to post-traumatic stress disorder (PTSD), of which re-experiencing is the core symptom. However, neuroimaging studies of sex differences in re-experiencing in the context of the trauma of losing one's only child and PTSD are scarce; comparisons of the functional networks from the hippocampal subfields to the thalamus might clarify the neural basis. Methods: Thirty couples without any psychiatric disorder who lost their only child (non-PTSD group), 55 patients with PTSD, and 50 normal controls underwent resting-state functional magnetic resonance imaging. The functional connectivity (FC) from the hippocampal subregions to the thalamus and the correlations of FC with re-experiencing symptoms were analyzed within and between the sexes. Results: Compared with husbands without PTSD, wives without PTSD had higher re-experiencing symptoms and weaker FC between the right hippocampal cornu ammonis 3 (RCA3) and the right thalamus (RT; RCA3-RT). Moreover, only the correlation between the RCA3-RT FC and re-experiencing in wives without PTSD was significant. Among the three groups, only the RCA3-RT FC in female subjects was markedly different. Additionally, the RCA3-RT FC in wives without PTSD was remarkably lower relative to female patients with PTSD. Conclusion: Wives without PTSD who lost their only child had worse re-experiencing symptoms relative to their husbands, which was associated with the FC alteration between the hippocampal subregions and the thalamus. Importantly, the low level of the RCA3-RT FC may play a potentially protective role against the development of PTSD in wives who have lost their only child.

Project description:BACKGROUND:In order improve the quality of birth care and women satisfaction with birthing process it is recommended that every woman should be offered the option to experience labour and childbirth with a companion of her choice. Involving husbands who are decision makers in the household may a play role in reducing maternal mortality which is unacceptably high despite the targeted goal to reduce this mortality up to three quarters as targeted in the MDGs by 2015. This is still addressed in the Sustainable Development Goals (SDGs) of 2015/30. This study aimed to explore the experiences and perceptions of husbands' support of their wives during pregnancy, labour and deliveries in Tanzania. METHODS:Qualitative descriptive study design was employed; involving men aged between 24 and 63?years. Participants were selected purposefully at the clinic and in labour ward of SekouToure Regional Referral Hospital (SRRH). The in-depth interview, guided by semi structured interview guide was used to collect the audio recorded and hand written information. Data were analysed using qualitative content analysis. RESULTS:Nine semi-structured interviews were conducted with husbands of women attended for antenatal care and those came for deliveries. Four themes emerged; Demonstrating care, love and affection, adopting modern life style, observing women's right and meeting social economic difficulties. Husbands' support to their partners is a good behaviour practiced during matrimonial lives. Husbands who support their partners during pregnancy and delivery consider themselves as being modern men as they at home take duties beside their usual tasks to let their wives have adequate time to rest during pregnancy. Poor road infrastructure makes difficult to get transport to the healthcare facility especially when labour is imminent. Also ward infrastructure is not supportive to accommodate husbands when they accompany their wives to the healthcare facility. CONCLUSIONS:The healthcare settings in low income countries need to accommodate men during the routine antenatal and intranatal care for the positive outcome of labour and delivery. Educating men on importance of active involvement in reproductive and child health services is important. Exploratory research should be conducted to understand how education and urbanisation affects men involvement in maternal and child health specifically in the low income countries.

Project description:While age-related volumetric changes in human hippocampal subfields have been reported, little is known about patterns of subfield functional connectivity (FC) in the context of healthy ageing. Here we investigated age-related changes in patterns of FC down the anterior-posterior axis of each subfield. Using high resolution structural MRI we delineated the dentate gyrus (DG), CA fields (including separating DG from CA3), the subiculum, pre/parasubiculum, and the uncus in healthy young and older adults. We then used high resolution resting state functional MRI to measure FC in each group and to directly compare them. We first examined the FC of each subfield in its entirety, in terms of FC with other subfields and with neighboring cortical regions, namely, entorhinal, perirhinal, posterior parahippocampal, and retrosplenial cortices. Next, we analyzed subfield to subfield FC within different portions along the hippocampal anterior-posterior axis, and FC of each subfield portion with the neighboring cortical regions of interest. In general, the FC of the older adults was similar to that observed in the younger adults. We found that, as in the young group, the older group displayed intrinsic FC between the subfields that aligned with the tri-synaptic circuit but also extended beyond it, and that FC between the subfields and neighboring cortical areas differed markedly along the anterior-posterior axis of each subfield. We observed only one significant difference between the young and older groups. Compared to the young group, the older participants had significantly reduced FC between the anterior CA1-subiculum transition region and the transentorhinal cortex, two brain regions known to be disproportionately affected during the early stages of age-related tau accumulation. Overall, these results contribute to ongoing efforts to characterize human hippocampal subfield connectivity, with implications for understanding hippocampal function and its modulation in the ageing brain.
