Trends in the Application of Dyadic Coping in Older Adults with Mild Cognitive Impairment and Their Spouses

Dyadic coping plays an important role in older adults with mild cognitive impairment and their spouses. Significant correlations were found between dyadic coping and self-efficacy, anxiety and depression, marital quality, and quality of life in elderly patients with mild cognitive impairment and their spouses, and there were gender differences, with a 36.1% [P = 0.028, OR = 0.639, 95% CI (0.429, 0.952)] and 54% [P = 0.004, OR = 0.460, 95% CI (0.269, 0.785)] reduction in the risk of MCI and dementia for older men aged 65 - 69 years with a spouse and for those aged 80 years and older with a spouse, respectively. In contrast, there was no significant difference in the association between having or not having a spouse and developing MCI and dementia in older women (all P > 0.05). Psychosocial interventions, skills interventions, and exercise from the perspective of dyadic relationships were effective in improving the physical and mental health of older adults with mild cognitive impairment and their spouses. However, there is a lack of specific intervention programs for dyadic relationships in the local cultural context as an entry point. Therefore, it is necessary to draw on internal and external relevant literature to treat both partners as a whole for intervention, provide personalized social, cognitive and motor therapy for patients and promote the integration and participation of caregivers, help patients and spouses to improve the sense of well-being and intimacy, reduce the burden of caregivers, and build a dyadic coping intervention program suitable for elderly patients with mild cognitive impairment in China. The current article aims to provide a conceptual review focusing on dyadic coping care to inform the development of a dyadic intervention program suitable for older adults with mild cognitive impairment in China. This review outlines the theoretical concepts, assessment tools, current state of research, and intervention methods for mild cognitive impairment and dyadic coping.

Spillover and quantile linkage between oil price shocks and stock returns: new evidence from G7 countries

The link between crude oil price and stock returns of the Group of Seven(G7)countries(Canada,France,Germany,Italy,Japan,the United Kingdom,and the United States)was analyzed in this study using monthly data from January 1999 to March 2020.We adopt a similar approach to Kilian(Am Econ Rev 99(3):1053–1069,2009)and construct a structural vector autoregression framework to decompose crude oil price shocks into oil supply shock,oil aggregate demand shock,and oil-specific demand shock.We then explore the distinct effects of different kinds of oil price shocks from various sources.Based on the decomposed oil price shocks,we apply the connectedness approach and QQ regression to find time-varying co-movements and tail dependence between oil price shocks and G7 stock returns.There is no general correlation between the decomposed oil prices and stock returns in these countries.The effects of oil price shocks on stock returns across different stock market conditions appear to be heterogeneous.Oil supply shock appears to be a net transmitter of spillover effects for all G7 countries within the sample period.

Risk factors and birth outcomes of preterm birth subtypes:a case-control study of singleton natural pregnancy

Objective The objective of the study was to identify the risk factors correlated with spontaneous preterm birth(SPTB)and iatrogenic preterm birth(IPTB),as well as to compare the pregnancy outcomes between SPTB and IPTB.Materials and methods A total of 1676(343 SPTB,144 IPTB and 1189 full-term control group)cases were collected from the International Peace Maternity&Child Health Hospital of Shanghai between August 2018 and October 2020.A case-control study was conducted to explore the risk factors and pregnancy outcomes of SPTB and IPTB.Results The study identified a set of risk factors for SPTB and IPTB,as well as differences in pregnancy outcomes.Reproductive tract infections and myoma of the uterus were the risk factors for SPTB(p<0.05).Fetal growth restriction,pre-eclampsia,intrahepatic cholestasis of pregnancy,fetal distress,placenta abnormality,oligohydramnios and scarred uterus were the risk factors for IPTB(p<0.05).Antenatal haemorrhage and placental abruption were the risk factors both for SPTBand IPTB(p<0.05).The pregnancy outcomes of the two PTB gubtypes differed,and birth woight,longth and 1-minute Apgar score of newborns were significantly lower in IPTB than in SPTB(p<0.05).Conclusion The risk factors of SPTBand IPTB are different,and IPTB is associated with a higher incidence of worse pregnancy outcomes than SPTB.
