Building stones of resilience of vulnerable older persons

Introduction: Vulnerable older persons need sufficient resilience to deal with (age-related) adversities and safeguard their quality of life. In this study, we investigate which sources of strength vulnerable older persons use to deal adversities. Methods: This qualitative study is based on fifteen narratives of community-dwelling vulnerable older persons in Belgium, who were selected through a ‘purposive sampling’ strategy. Results: Vulnerable older persons use various interrelated sources of strength situated on the individual, interactional, and contextual domains. On the individual domain, important sources of strength are having an optimistic life view and accepting the own vulnerabilities. On the interactional domain positive social relations, ‘the power of giving’ and social participation are sources of strength that benefit the quality of life of older persons, and on the contextual domain various welfare benefits are essential. Conclusion: It is crucial to stimulate those sources of strength, for example by removing contextual barriers that impede social participation. The results can guide empowering interventions that aim to reinforce the sources of strength of vulnerable older persons, which will positively affect their resilience and general well-being

De nood aan een krachtgerichte blik:Participatie en inclusie van ouderen

Onze maatschappij benut de krachten van ouderen veel te weinig, wat een participatief en inclusief ouderenbeleid sterk tegengaat. Wij schuiven empowerment naar voor als een cruciaal kader om het ouderenbeleid onder de loep te nemen, en zo de participatie, inclusie en het algemeen welzijn van ouderen te versterken

"Precious time together was taken away":Impact of COVID-19 restrictive measures on social needs and loneliness from the perspective of residents of nursing homes, close relatives, and volunteers

During the COVID-19 outbreak in March 2020, restrictive measures (e.g., prohibiting physical visits and group activities) were introduced in nursing homes to protect older residents. Although the importance of social contacts and social activities to fulfill social needs and avoid loneliness is known, these were challenged during the pandemic. This qualitative study specifically focused on how residents, close relatives, and volunteers in nursing homes experienced the restrictive measures in retrospect and gained insights into the impact of the restrictive measures on social needs and loneliness, and the lessons that could be learned. Thirty semi-structured, face-to-face interviews with residents and close relatives, and one online focus group with ten volunteers, were conducted. Recruitment took place at psychogeriatric and somatic units in the Northern, Eastern and Southern regions of the Netherlands and Flanders, Belgium. The interviews and focus group were transcribed verbatim, and an open, inductive approach was used for analysis. Alternative ways of social contact could not fully compensate for physical visits. Generally, participants reported that it was a difficult time, indicated by feelings of loneliness, fear, sadness, and powerlessness. A great diversity in loneliness was reported. The most important reasons for feeling lonely were missing close social contacts and social activities. The diversity in the impact of restrictive measures depended on, e.g., social needs, coping strategies, and character. Restrictive COVID-19 measures in nursing homes resulted in negative emotions and unmet social needs of residents, close relatives, and volunteers. During future outbreaks of the COVID-19 virus or another virus or bacterium, for which restrictive measures may be needed, nursing homes should actively involve residents, close relatives, and volunteers to balance safety, self-determination, and well-being

Context matters: Explaining how and why mobilizing context influences motivational dynamics

The emphasis in the social-psychological collective action literature is on why individuals take part in collective action; however, it does not elaborate on how different mobilizing contexts may appeal to distinct motivational dynamics to participate. The present study connects the microlevel of motivational dynamics of individual protesters with the mesolevel of social movement characteristics. To do so a field study was conducted. Protesters were surveyed in the act of protesting in two different demonstrations in two different town squares simultaneously organized by two social movements at exactly the same time against the same budget cuts proposed by the same government. But with one fundamental difference, the movements emphasized different aspects of the policies proposed by the government. This most similar systems design created a unique natural experiment, which enabled the authors to examine whether the motivational dynamics of individual protesters are moderated by the social movement context. Previous research suggested an instrumental path to collective action, and the authors added an ideology path. The authors expected and found that power-oriented collective action appeals to instrumental motives and efficacy and that value-oriented collective action appeals to ideological motives, and, finally, that efficacy mediates on instrumental motives and motivational strength, but only so in power-oriented action. © 2009 The Society for the Psychological Study of Social Issues

Longitudinal changes of telomere length and epigenetic age related to traumatic stress and post-traumatic stress disorder

Several studies have reported an association between traumatic stress and telomere length suggesting that traumatic stress has an impact on ageing at the cellular level. A newly derived tool provides an additional means to investigate cellular ageing by estimating epigenetic age based on DNA methylation profiles. We therefore hypothesise that in a longitudinal study of traumatic stress both indicators of cellular ageing will show increased ageing. We expect that particularly in individuals that developed symptoms of post-traumatic stress disorder (PTSD) increases in these ageing parameters would stand out.From an existing longitudinal cohort study, ninety-six male soldiers were selected based on trauma exposure and the presence of symptoms of PTSD. All military personnel were deployed in a combat zone in Afghanistan and assessed before and 6 months after deployment. The Self-Rating Inventory for PTSD was used to measure the presence of PTSD symptoms, while exposure to combat trauma during deployment was measured with a 19-item deployment experiences checklist. These groups did not differ for age, gender, alcohol consumption, cigarette smoking, military rank, length, weight, or medication use. In DNA from whole blood telomere length was measured and DNA methylation levels were assessed using the Illumina 450K DNA methylation arrays. Epigenetic ageing was estimated using the DNAm age estimator procedure.The association of trauma with telomere length was in the expected direction but not significant (. B=. -10.2, p=. 0.52). However, contrary to our expectations, development of PTSD symptoms was associated with the reverse process, telomere lengthening (. B=. 1.91, p=. 0.018). In concordance, trauma significantly accelerated epigenetic ageing (. B=. 1.97, p=. 0.032) and similar to the findings in telomeres, development of PTSD symptoms was inversely associated with epigenetic ageing (. B=. -0.10, p=. 0.044). Blood cell count, medication and premorbid early life trauma exposure did not confound the results.Overall, in this longitudinal study of military personnel deployed to Afghanistan we show an acceleration of ageing by trauma. However, development of PTSD symptoms was associated with telomere lengthening and reversed epigenetic ageing. These findings warrant further study of a perhaps dysfunctional compensatory cellular ageing reversal in PTSD

Towards broad spectrum activity-based glycosidase probes: synthesis and evaluation of deoxygenated cyclophellitol aziridines

Activity-based protein profiling has emerged as a powerful tool for visualizing glycosidases in complex biological samples. Several configurational cyclophellitol isomers have been shown to display high selectivity as probes for glycosidases processing substrates featuring the same configuration. Here, a set of deoxygenated cyclophellitols are presented which enable inter-class profiling of [small beta]-glucosidases and [small beta]-galactosidases

Muscarinic receptor subtypes and signalling involved in the attenuation of isoprenaline-induced rat urinary bladder relaxation

β-Adrenoceptors are important mediators of smooth muscle relaxation in the urinary bladder, but the concomitant presence of a muscarinic agonist, e.g., carbachol, can attenuate relaxation responses by reducing potency and/or efficacy of β-adrenoceptor agonists such as isoprenaline. Therefore, the present study was designed to explore the subtypes and signalling pathways of muscarinic receptors involved in the attenuation of isoprenaline-induced isolated rat detrusor preparations using novel subtype-selective receptor ligands. In radioligand binding studies, we characterized BZI to be a M3-sparing muscarinic agonist, providing selective M2 stimulation in rat bladder, and THRX-182087 as a highly M2-selective antagonist. The use of BZI and of THRX-182087 in the presence of carbachol enabled experimental conditions with a selective stimulation of only M2 or M3 receptors, respectively. Confirming previous findings, carbachol attenuated isoprenaline-induced detrusor relaxation. M2-selective stimulation partly mimicked this attenuation, indicating that both M2 and M3 receptors are involved. During M3-selective stimulation, the attenuation of isoprenaline responses was reduced by the phospholipase C inhibitor U 73,122 but not by the protein kinase C inhibitor chelerythrine. We conclude that both M2 and M3 receptors contribute to attenuation of β-adrenoceptor-mediated relaxation of rat urinary bladder; the signal transduction pathway involved in the M3 component of this attenuation differs from that mediating direct contractile effects of M3 receptors

A Genetic Signature of Spina Bifida Risk from Pathway-Informed Comprehensive Gene-Variant Analysis

Despite compelling epidemiological evidence that folic acid supplements reduce the frequency of neural tube defects (NTDs) in newborns, common variant association studies with folate metabolism genes have failed to explain the majority of NTD risk. The contribution of rare alleles as well as genetic interactions within the folate pathway have not been extensively studied in the context of NTDs. Thus, we sequenced the exons in 31 folate-related genes in a 480-member NTD case-control population to identify the full spectrum of allelic variation and determine whether rare alleles or obvious genetic interactions within this pathway affect NTD risk. We constructed a pathway model, predetermined independent of the data, which grouped genes into coherent sets reflecting the distinct metabolic compartments in the folate/one-carbon pathway (purine synthesis, pyrimidine synthesis, and homocysteine recycling to methionine). By integrating multiple variants based on these groupings, we uncovered two provocative, complex genetic risk signatures. Interestingly, these signatures differed by race/ethnicity: a Hispanic risk profile pointed to alterations in purine biosynthesis, whereas that in non-Hispanic whites implicated homocysteine metabolism. In contrast, parallel analyses that focused on individual alleles, or individual genes, as the units by which to assign risk revealed no compelling associations. These results suggest that the ability to layer pathway relationships onto clinical variant data can be uniquely informative for identifying genetic risk as well as for generating mechanistic hypotheses. Furthermore, the identification of ethnic-specific risk signatures for spina bifida resonated with epidemiological data suggesting that the underlying pathogenesis may differ between Hispanic and non-Hispanic groups
