Depression and Elevated Inflammation Among Chinese Older Adults: Eight Years After the 2003 SARS Epidemic

Post-traumatic growth in later-life cognitive function? Evidence from the 1976 Great Tangshan Earthquake

OBJECTIVES

This study aimed to explore the long-term impacts of exposure to earthquake in adolescence on later-life cognitive function in China.

METHODS

Data were from the 2015 China Health and Retirement Longitudinal Study (CHARLS). Our analytical sample comprised 4394 participants aged 49 to 78 from two birth cohorts born between 1937 and 1966: exposed cohort during adolescence (born between 1952 and 1966), and non-exposed cohort during adolescence (born between 1937 and 1951). We defined earthquake exposure as the exposure severity of the 1976 Great Tangshan Earthquake (GTE). We selected community environmental characteristics as our key moderators. A difference-in-differences (DID) method was employed to estimate the long-term impact of the GTE on later-life cognitive function.

RESULTS

We found that exposure to the earthquake during adolescence resulted in higher scores of later-life cognitive function (for males: β = 2.18; 95% CI: 0.70-3.66; for females: β = 1.22; 95% CI: 0.11-2.33). For males, this impact was moderated by community environmental characteristics including the old-age allowance program (β = 3.07; 95% CI: 1.94-4.19) and the condition of basic community infrastructures (β = 1.52; 95% CI: 0.84-2.19).

CONCLUSIONS

Our study supports the post-traumatic growth theory. This finding suggest that individuals with early-life traumatic exposure need to be focused on. Additionally, improving the conditions of community infrastructures and establishing a community environment with comfort and security may be pretty important for promoting cognitive function and post-traumatic growth.

Differences in the influence of daily behavior on health among older adults in urban and rural areas: evidence from China

Background

As the population of older adult in China keeps growing, the degree of aging is becoming increasingly serious and the health of older adults is a growing concern. Comparing the personal characteristics and health levels of urban and rural older adults and determining the relationship between these factors are of great significance in maintaining their health. In addition, exploring how these relationships differ between urban and rural areas is important.

Method

This study conducted a literature review to examine the impact of various factors on the physical and mental health of older adults in urban and rural areas in China. Moreover, based on cross-sectional data from the 2017 Chinese General Social Survey (CGSS), urban-rural differences in the factors' degree of influence on the perceived health of older adults were studied using multiple logistic regression.

Results

Regular physical exercise had a powerful protective effect on urban older adults' physical and mental health, whereas regular participation in social activities had a positive impact on rural older adults' health. Low income, low educational level, low social trust, lack of a partner, and having more than one child negatively affected the physical health of rural older people. Low socioeconomic status had a negative impact on rural people's health both in mind and body. Overall, the rural adults' health status was found to be relatively low and deserves more attention.

Conclusion

This study demonstrated that older people's physical and mental health levels can be significantly affected by the frequency of daily activities and individual and family characteristics. Furthermore, urban-rural differences were observed. These findings could provide feasible suggestions for governments, communities, and older adults' family members to help alleviate health inequality.

Computational approach investigation bioactive molecules from Saussurea Costus plant as SARS-CoV-2 main protease inhibitors using reverse docking, molecular dynamics simulation, and pharmacokinetic ADMET parameters

SARS-COV-2 virus causes (COVID-19) disease; it has become a global pandemic since 2019 and has negatively affected all aspects of human life. Scientists have made great efforts to find a reliable cure, vaccine, or treatment for this emerging disease. Efforts have been directed towards using medicinal plants as alternative medicines, as the active chemical compounds in them have been discovered as potential antiviral or anti-inflammatory agents. In this research, the potential of Saussurea costus (S. Costus) or QUST Al Hindi chemical consistent as potential antiviral agents was investigated by using computational methods such as Reverse Docking, ADMET, and Molecular Dynamics with different proteases COVID-19 such as PDB: 2GZ9; 6LU7; 7AOL, 6Y2E, 6Y84. The results of Reverse Docking the complex between 6LU7 proteases and Cynaropicrin compound being the best complex, as the same result, is achieved by molecular dynamics. Also, the toxicity testing result from ADMET method proved that the complex is the least toxic and the safest possible drug. In addition, 6LU7-Cynaropicrin complex obeyed Lipinski rule; it formed ≤5 H-bond donors and ≤10 H bond acceptors, MW < 500 Daltons, and octanol/water partition coefficient <5.

Social trust and stress symptoms among older adults during the COVID-19 pandemic: evidence from Asia

Objectives

To investigate whether social trust is associated with more stress symptoms among middle-aged and older adults in six East and Southeast Asia regions during the COVID-19 pandemic.

Methods

This multi-region study used cross-sectional survey data collected in May 2020. Participants were a probability-based internet sample of adults aged 55 or older.

Results

Government trust was negatively associated with stress in Singapore and South Korea. Higher levels of health care trust were significantly associated with less stress in Singapore and Taiwan. Trust in neighbors was associated with a higher likelihood of stress in Hong Kong and a lower likelihood in Singapore. Social trust was not associated with stress in Japan or Thailand.

Discussion

Findings suggest the level of social trust in relation to stress substantially varied by region. Interventions to strengthen trust during COVID-19 and other major health crises need to be tailored to fit regions’ unique circumstances.

The association between the community SARS exposure and allostatic load among Chinese older adults

Objectives

Previous studies have found that severe acute respiratory syndrome (SARS) was associated with the physical and psychological stress of those infected. However, research is sparse regarding the long‐term health consequence of community SARS exposure for older adults.

Methods

Using data from the 2011 and 2015 China Health and Retirement Longitudinal Study (CHARLS), we estimated multilevel regression models of allostatic load (AL) in the years after the SARS epidemic among 7735 respondents. Interaction terms between SARS epidemic exposure and social participation or community environment were included to examine potential effects.

Results

We found that community SARS exposure was associated with greater AL for those who had no social participation. Among those who were in worse community environment, community SARS exposure was strongly related to elevated load in the cardiovascular system. However, for those had social participation and lived in better community environment, community SARS exposure manifested no association with AL years later. Active social participation and better community environment could offset the negative association between SARS exposure and AL.

Conclusions

Taken together, these findings helped determine the positive direction of future social efforts and policy decisions to guide the global recovery from the devastating COVID‐19 pandemic.

Update Advances on C-Reactive Protein in COVID-19 and Other Viral Infections

Severe coronavirus disease 2019 (COVID-19) can manifest as a viral-induced hyperinflammation with multiorgan dysfunction. It has been documented that severe COVID-19 is associated with higher levels of inflammatory mediators than a mild disease, and tracking these markers may allow early identification or even prediction of disease progression. It is well known that C-reactive protein (CRP) is the acute-phase protein and the active regulator of host innate immunity, which is highly predictive of the need for mechanical ventilation and may guide escalation of treatment of COVID-19-related uncontrolled inflammation. There are numerous causes of an elevated CRP, including acute and chronic responses, and these can be infectious or non-infectious in etiology. CRP are normally lacking in viral infections, while adaptive immunity appears to be essential for COVID-19 virus clearance, and the macrophage activation syndrome may explain the high serum CRP contents and contribute to the disease progression. Nevertheless, for the assessment of host inflammatory status and identification of viral infection in other pathologies, such as bacterial sepsis, the acute-phase proteins, including CRP and procalcitonin, can provide more important information for guiding clinical diagnosis and antibiotic therapy. This review is aimed to highlight the current and most recent studies with regard to the clinical significance of CRP in severe COVID-19 and other viral associated illnesses, including update advances on the implication of CRP and its form specifically on the pathogenesis of these diseases. The progressive understanding in these areas may be translated into promising measures to prevent severe outcomes and mitigate appropriate treatment modalities in critical COVID-19 and other viral infections.

Bereavement from COVID-19, Gender, and Reports of Depression among Older Adults in Europe

Objectives

The coronavirus disease 2019 (COVID-19) pandemic has left older adults around the world bereaved by the sudden death of relatives and friends. We examine if COVID-19 bereavement corresponds with older adults’ reporting depression in 27 countries and test for variations by gender and country context.

Method

We analyze the Survey of Health, Ageing and Retirement in Europe COVID-19 data collected between June and August 2020 from 51,383 older adults (age 50–104) living in 27 countries, of whom 1,363 reported the death of a relative or friend from COVID-19. We estimate pooled multilevel logit regression models to examine if COVID-19 bereavement is associated with self-reported depression and worsening depression, and we test whether national COVID-19 mortality rates moderate these associations.

Results

COVID-19 bereavement is associated with significantly higher probabilities of both reporting depression and reporting worsened depression among older adults. Net of one’s own personal loss, living in a country with the highest COVID-19 mortality rate is associated with women’s reports of worsened depression but not men’s. However, the country’s COVID-19 mortality rate does not moderate associations between COVID-19 bereavement and depression.

Discussion

COVID-19 deaths have lingering mental health implications for surviving older adults. Even as the collective toll of the crisis is apparent, bereaved older adults are in particular need of mental health support.

The impact of Covid-19-related distancing on the well-being of nursing home residents and their family members: a qualitative study

OBJECTIVES

The aim of this study is to examine the consequences of Covid-19-related isolation and social restrictions on the well-being of nursing home residents and their family members, and to analyze how distancing has affected the relationships of family members with residents and the nursing home staff.

DESIGN

The data consist of 41 thematic one-on-one interviews conducted during May-December 2020 with family members of nursing home residents. Convenience sampling was utilized by asking several nursing homes in different parts of Finland to relay a contact request from the researchers to the residents' family members. The main themes of the interviews were lockdown and visiting restrictions. Subthemes included the frequency of visits, other means of interaction, changes in the relationships of family members with their loved ones and with nursing home staff, and the feelings aroused by the situation. The interviews were audio recorded and transcribed verbatim, resulting in 794 pages of data.

METHOD

The qualitative study uses inductive content analysis. NVivo12 software facilitated the systematic coding of the data.

RESULTS

According to the family members, distancing aggravated the residents' pre-existing conditions: they reported a sudden progression in memory disorders and significant deterioration in physical abilities, for example. Both residents and family members experienced anxiety, grief, and severe stress, and family members expressed concern that residents might die due to a lack of social contact and activity. Family members were also frustrated about not being able to touch their relatives or participate in their care, and therefore sometimes thought that their visits were useless. New forms of interaction with family members, introduced by the nursing homes, were appreciated. However, some family members perceived the interactional protocols as unfair and complained about insufficient information.

CONCLUSIONS

The findings underline the need for nursing homes to implement a good interactional protocol. Overall, the results show that the measures taken to protect residents' health during the Covid-19 outbreak were short-sighted in terms of the social dimension of well-being. It is therefore important to continue developing safe and humane solutions for interaction when social restrictions are in place. Tweetable abstract: Covid-19-related distancing has caused anxiety, grief, and severe stress for nursing home residents and their family members.
