Abstract Loneliness is defined as a distressing feeling that arises from the discrepancy between one’s desired and perceived social relationships. Theorists have posited that loneliness involves affective, cognitive, and behavioral components that can be noticed by close family or friends. Little is known about whether social withdrawal, a behavioral marker of loneliness observed by knowledgeable others, shares similar associations with cognition as self-reported loneliness. The present study examined whether self-reported and informant-rated loneliness are related to cognitive function in older adulthood. Data come from Harmonized Cognitive Assessment Protocol subsample included in three national aging studies from the US (HRS; N = 2,821, Mage = 75.8), England (ELSA; N = 896, Mage = 73.6), and India (LACI-DAD; N = 2,994, Mage = 69.3). Respondents reported on 1-item loneliness and informants rated the respondent’s withdrawal behavior. Regression models were used to analyze the association between both measures of loneliness and cognition, controlling for respondent (age, gender, education, race/ethnicity) and informant (age, gender, education, spouse, known years, frequency of contact) covariates. Meta-analysis showed that both respondent-reported and informant-rated loneliness were independently associated with lower cognitive functioning (memory, speed–attention–executive, visuospatial ability, and fluency) and global cognition (MMSE). The associations between observed withdrawal and cognition did not vary by informant-level characteristics nor the respondent’s cognitive impairment status. The present study indicates that withdrawal behavior observed by informants is associated with cognitive function, supporting psychosocial observations provided by knowledgeable others can be utilized in detecting cognitive function.

Abstract Background Five-factor model (FFM) personality traits have been associated consistently with risk of Alzheimer’s disease and related dementias (ADRD). Less is known about how these traits are associated with functioning in specific domains of cognitive function in older adulthood. Methods Participants (N = 2865) were drawn from the 2016 Harmonized Cognitive Assessment Protocol sub-study of the Health and Retirement Study (HRS). Participants completed a battery of cognitive tasks that measured performance in five domains: Memory (eight tasks), speed-attention-executive (five tasks), visuospatial ability (three tasks), fluency (one task), and numeric reasoning (one task). Participants completed an FFM personality measure as part of the regular HRS assessment in either 2014 or 2016. Linear regression was used to examine the association between the traits and each cognitive task and composite scores for the five domains, controlling for age, sex, race, ethnicity, and education. We also tested whether the associations were moderated by these sociodemographic factors or mental status. Results Neuroticism was associated with worse performance on all of the cognitive tasks. Conscientiousness was associated with better performance across all five cognitive domains, although not necessarily with every task. Openness and Agreeableness were associated with better performance in all domains, except for numeric reasoning. Extraversion was associated with better speed-attention-executive and fluency. There was no robust evidence that the association between personality and cognition was moderated by sociodemographic characteristics or global cognitive function. Conclusions Personality traits have pervasive associations with functioning across five cognitive domains. Consistent with the literature on personality and risk of ADRD, Neuroticism and Conscientiousness were associated with cognitive performance in the expected direction in all domains. Extraversion was the only trait that showed domain-specific associations. The present research supports models of personality and health in the context of cognition and suggests that personality is associated with intermediate markers of cognitive health.

Centered Care

Abstract Background and Objectives The concept of person-centered care has been utilized/adapted to various interventions to enhance health-related outcomes and ensure the quality of care delivered to persons living with dementia. A few systematic reviews have been conducted on the use of person-centered interventions in the context of dementia care, but to date, none have analyzed intervention effect by intervention type and target outcome. This study aimed to review person-centered interventions used in the context of dementia care and examine their effectiveness. Research Design and Methods A systematic review and meta-analysis were conducted. We searched through five databases for randomized controlled trials that utilized person-centered interventions in persons living with dementia from 1998 to 2019. Study quality was assessed using the National Institute for Health and Clinical Excellence. The outcomes of interest for the meta-analysis were behavioral and psychological symptoms in dementia (BPSD) and cognitive function assessed immediately after the baseline measurement. Results In total, 36 studies were systematically reviewed. Intervention types were: reminiscence, music, and cognitive therapies, and multisensory stimulation. Thirty studies were included in the meta-analysis. Results showed a moderate effect size for overall intervention, a small one for music therapy, and a moderate one for reminiscence therapy on BPSD and cognitive function. Discussion and Implications Generally speaking, person-centered interventions showed immediate intervention effects on reducing BPSD and improving cognitive function, although the effect size and significance of each outcome differed by intervention type. Thus, healthcare providers should consider person-centered interventions as a vital element in dementia care.

Aims Recently, more and more attention has been drawn on the long-term effects of insulin glargine. Here we strived to estimate the association of cancer occurrence with the use of insulin glargine. Methods We searched all the publications regarding the association between cancer occurrence and the use of insulin glargine using the US National Library of Medicine's PubMed database. Data were independently extracted and analyzed using random or fixed effects meta-analysis depending upon the degree of heterogeneity. Results Seven cohort studies were included in the meta-analysis. Cancer occurrence had no significant difference in glargine-treated patients compared to patients treated with other insulins (RR=0.86, 95% CI=0.69–1.07, p=0.17, Pheterogeneity <0.00001). In our subgroup analysis, glargine, compared to other insulins, did not increase the risk of breast cancer (RR=1.14, 95% CI=0.65–2.02, p=0.65, Pheterogeneity=0.002), prostate cancer (RR=1.00, 95% CI=0.79–1.26, p=0.99, Pheterogeneity=0.78), pancreatic cancer (RR=0.57, 95% CI=0.14–2.35, p=0.44, Pheterogeneity=0.0002) and gastrointestinal cancer (RR=0.80, heterogeneity 95% CI=0.62–1.02, p=0.07, Pheterogeneity=0.86). Conclusions This meta-analysis of open-label studies does not support an increased cancer risk in patients treated with insulin glargine. The result provides confidence for the development of insulin glargine, but needs confirmation by further clinical studies.

Risk For Depression

ABSTRACTBackground: We assessed the relationship between cognitive impairment (including mild cognitive impairment with no signs of dementia, and dementia) and risk for depression in old age (60 years and older).Methods: MEDLINE, EMBASE and the Cochrane Library database were used to identify potential studies. All of the clinical studies that produced data on the association between cognitive function and risk of depression among individuals aged 55 years or older were identified and included in this review. The studies were classified into cross-sectional and longitudinal subsets. The quantitative meta-analysis of cross-sectional and longitudinal studies were performed. For prevalence and incidence rates of depression, odds risk (OR) and relative risk (RR) were calculated, respectively.Results: Since all but two studies found in the search were for individuals aged 60 years or over, we assessed and reported on results for this larger group only. In this review we included 13 cross-sectional and four prospective longitudinal studies. The quantitative meta-analysis showed that, in old age, individuals with non-dementia cognitive impairment had neither significant higher prevalence nor incidence rates of depression than those without (odds risk (OR): 1.48, 95% confidence intervals (95% CI): 0.87–2.52; relative risk (RR): 1.12, 95% CI: 0.62–2.01). In old age, individuals with dementia had both significant higher prevalence and incidence rates of depression than those without (OR: 1.82, 95% CI: 1.15–2.89; RR: 3.92, 95% CI: 1.93–7.99).Conclusions: Despite the methodological limitations of this meta-analysis, we found that in old age, there was no association between depression and cognitive impairment with no dementia; however, there was a definite association between depression and dementia and thus dementia might be a risk for depression.

Abstract With the accelerating progress of population aging, cognitive dysfunction is becoming increasingly prevalent. Exercise, as a promising non-pharmaceutical therapy, showed favorable effects on cognitive function. But which type is the most effective exercise treatment is still unclear. This study compared the efficacy of different types of exercise interventions based on network meta-analysis and aimed to explore the optimal exercise treatment for cognitive decline. The electronic databases of PubMed, Web of Science, Embase, Cochrane Central Register of Controlled Trials, SPORTDiscus, PsycInfoy, and OpenGrey were searched from inception to September 2019. We only included randomized controlled trials that examined the effectiveness of exercise interventions in people with MCI or dementia. Primary outcomes were global cognition, executive function and memory function. Standard mean difference (SMD) and its 95% confidence interval (CI) were calculated to estimate the effect sizes. Finally, 73 articles with 5748 participants were included. The results showed all kinds of exercise interventions were effective on global cognition and resistance exercise was probably the most effective exercise treatment to prevent the decrease of global cognition (SMD=1.05, 95%CI 0.56-1.54), executive function (SMD=0.85, 95%CI 0.21-1.49) and memory function (SMD=0.32, 95%CI 0.01-0.63) for people with cognitive dysfunction. Subgroup analysis revealed multi-component exercise showed more favorable effects on global cognition (SMD=0.99, 95%CI 0.44-1.54) and executive function (SMD=0.72, 95%CI 0.06-1.38) in people with MCI. In conclusion, resistance exercise tended to be the optimal exercise type for people with cognitive dysfunction, especially for people with dementia. And multi-component exercise also should be recommended for people with MCI.
