Semi-structured Interview to Analyse Needs of Family Caregivers for People with Dementia

Background: Globally, our population is aging. The prevalence of dementia increases dramatically with advancing age. Caring for a person living with dementia affects different people in different ways. Objectives: In response, this research study was conducted to explore the role, needs and stress of family caregivers (FCGs) for people with dementia as a means of understanding their experience of caring. The study also targeted to identify coping strategies employed by FCGs and explore positive aspects of the caring relationship in relation to their quality of life, information needs, day care and respite care, and emotional support.Methods: To measure individuals’ uniqueness and their specificity in their care-giving experience, this study employed qualitative research design, through semi-structure interview (SSI) as research methods to explore the grounded theory on role, needs and stress of caregivers. The needs of caregivers were documented under their continuum of care: seeking understanding, stabilization, preparation, implementation and adaptation. Results: Twenty FCG were recruited through purposeful sampling. Results indicated caregiving to dementia is a very demanding task both mentally and physically. Two main categories were formulated from the data: the impact of caring and the need to support their caregivers' role. The need to develop understanding of the effectiveness of specific health and social care interventions showed as highly important. Conclusion: Individuals’ perspectives need to be integrated into future service planning and decision-making processes. Suggested strategies from FCG’ perspectives that can potentially alleviating their care stress would be illustrated

Information Communication Technology as Instrumental Activities of Daily Living for Aging-in-Place in Chinese Older Adults With and Without Cognitive Impairment: The Validation Study of Advanced Instrumental Activities of Daily Living Scale

Background: The capability in applying information communication technology (ICT) is crucial to the functional independence of older peoples of community living nowadays. The proper assessment of individuals' capability of ICT application is the corner stone for the future development of telemedicine in our aging population. Methods: With the recruitment of 300 participants of different functional and social background in home-living, hostel-living, and care-and-attention home living; and through assessing the ability of individuals in instrumental activities of daily living and cognitive assessments, this study aimed at capturing the content validity and construct validity of the Advanced Instrumental Activities of Daily Living (AIADL scale). In addition, this study assess the ability of older peoples in applying ICT and how the functional and social background affects their independence in aging-in-place. Results: The AIADL scale showed good test-retest reliability and good-to-excellent internal consistency. To determine if items of the AIADL scale measure various aspects of community living, exploratory factor analysis revealed a two-factor structure with “home living and management” and “community living”. Validity analysis with the known-groups method showed a high overall accuracy of prediction of individuals' capability of independent living in the community. Conclusions: The AIADL scale is a valid and reliable instrument to assess the ability of older adults in handling ICT as part of their instrumental activities in daily living. The scale can reflect capability of older peoples in applying ICT. This instrument can serve as a reference in measuring readiness of individuals in receiving telemedicine and their ability of aging-in-place

Adoption and Handling Information Communication Technology as Instrumental Activities of Daily Living for Aging-in-Place in Chinese Older Adults

(Background) The use of information communication technology and smartphone application are crucial to individuals’ functional independence of community living. Previous studies did not reveal how older adults’ in applying the information communication technology will affect their aging-in-place in our contemporary community. (Methods) This study aimed at developing the psychometric properties of the instrument named Advanced Instrumental Activities of Daily Living (AIADL), and to explore the adoption and handling information communication technology in instrumental activities of daily living for aging-in-place of older adults. 100 home-living participants who are functionally and socially independent, 100 hostel-living participants who are functionally independent but need social assistance, and 100 care-and-attention home living participants who need environment support and assistance in daily functioning were recruited for this study. (Results) AIADL showed good test-retest reliability and good-to-excellent internal consistency. Exploratory factor analysis revealed a two-factor structure with “home living and management” and “community living”. Validity analysis with the known-groups method showed a high overall accuracy of prediction of individuals’ capability of independent living in the community. (Conclusions) AIADL is a valid and reliable instrument to assess older adults’ ability in handling contemporary instrumental activities in their daily life. This instrument can serve as a reference in measuring individuals’ ability of aging-in-place

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Risks and Mitigating Factors in Psychosocial Adjustment of Spousal Caregivers of People with Dementia

By applying the Stress Process Model to examine the characteristics of people with dementia and their spousal caregivers, this study aims to identify the potential risk and mitigating factors of psychosocial adjustment among the spousal caregivers. We recruited 80 care recipient-caregiver couples in Hong Kong and examined the relationships of socio-economic, care recipient’s, and caregiver’s factors with spousal caregivers’ psychosocial adjustment. It was found that care recipients’ cognitive functions were associated with caregivers’ reported frequencies of their behavioral and psychological symptoms of dementia (BPSD) (r = .30, p = .008), and caregivers’ perceived burden of caregiving (r = -.54, p = .008). Caregivers’ quality of life was associated with their perceived caregiving burden (r = -.82, p = .001) and self-efficacy (r = .32, p = .001). Upon further examining the caregiving model with these parameters, a significant multivariate general linear model was found with (F (1, 12) = 13.06, p = .001, partial eta square = .70, observed power = .99). Moreover, female caregivers reported higher sense of caregiving stress and poorer quality of life than male caregivers. This study found that the cognitive functions and BPSD of care recipients with dementia and perceived level of caregiving burden are strongly associated with degrees of psychosocial adjustment among their spousal caregivers. The self-perceived caregiving role in a family is also a possible confounding factor contributing to the perceived caregiving burden. To support in-home caregiving of people with dementia, strategies to empower spousal caregivers to execute their caregiving roles are recommended
