Psychoneurodendocrine correlates of lymphocyte subsets during healthy ageing

Ageing has been associated with increased cortisol levels and absolute counts of T lymphocytes with memory phenotype. Although the mechanisms underlying these changes are still unknown, it has been speculated that this could be related to a dysfunction in FAS/CD95 expression in naive or memory cells. In this study, we investigated the role of psychoneuroendocrine variables in regulating CD95 expression on lymphocyte subsets. Forty-six elderly subjects (65-91 years) and 33 young adults (20-40 years) were recruited accordingly the SENIEUR protocol. The psychological status was measured by structured clinical interviews, salivary cortisol was assessed along the day (9, 12 and 22h) and peripheral blood lymphocytes were immunophenotyped. The elderly were more stressed, depressed and anxious than the young subjects. Cortisol levels were increased in the elderly, indicating an activation of the hypothalamic-pituitary-adrenal (HPA) axis. We observed reduced counts of CD45RA+CD95+ cells in the elderly compared to young adults. The elderly subjects also showed a reduced expression of CD3 and CD62L in contrast to increased CD95 expression in CD45RA+ cells. The emotional state was positively correlated with the lymphocyte markers. Our data suggest the healthy ageing is associated with psychoneuroendocrine alterations that may be implicated in the regulation of CD95 expression on peripheral T cells.     

The perception of problem drinkers by general hospital staff, general practitioners and alcoholic patients

A sample of 275 subjects (general hospital staff, general practitioners and alcoholic patients) was investigated regarding their perception of problem-drinkers. A set of semantic differential scales was used, and subjects were asked to evaluate the concepts of "problem drinker," "self" and "ideal self." Psychological distance was measured in terms of bipolar personality constructs between each of the above concepts. Significant differences were found between the groups in terms of concept evaluation and psychological distance. The implications of these findings for both research and treatment are discussed.

Association of habitual exercise with adults’ mental health following the Fukushima Daiichi nuclear power plant accident: the Fukushima Health Management Survey

IntroductionThe Great East Japan Earthquake and the Fukushima Daiichi nuclear power plant accident in March 2011 impacted survivors’ mental health. This study examined whether exercise habits and mental health conditions were associated, and whether the degree of the effect varied depending on time.MethodsA self-administered questionnaire was sent annually to former residents (born before April 1, 1998) in registered evacuation areas. Exercise habit was evaluated by participants’ exercise frequency, and responses were categorized into “almost never,” “once a week,” and “twice a week and more.” Data were tracked during three periods: fiscal year (FY) 2011–2012, 2012–2013, and 2013–2014. The association between baseline habitual exercise and new onset of psychological distress was assessed using the Japanese version of the Kessler 6-item Psychological Distress Scale and logistic regression analysis.ResultsA total of 1304 (5.7%) of 22,741, 1060 (4.7%) of 22,709, and 759 (3.6%) of 21,220 respondents had psychological distress in FY 2011–2012, 2012–2013, and 2013–2014, respectively. An association between exercise and psychological distress was observed in men in FY 2011–2012 (P for trend: 0.010) and in women in FY 2013–2014 (P for trend: 0.026). “Almost never” was associated with onset of psychological distress in men in FY 2011–2012 [odds ratio (OR): 1.317, 95% confidence interval (CI): 1.054–1.645] and in women in FY 2013–2014 (OR: 1.296, 95% CI: 1.027–1.636).ConclusionsExercise habit was associated with psychological distress, and its effect in time varied according to sex.     

Nursing Home Residents’ Functional Trajectories and Mortality After a Transfer to the Emergency Department

ObjectiveTo describe nursing home residents’ (NHRs) functional trajectories and mortality after a transfer to the emergency department (ED).DesignCase-control observational multicenter study.Setting and ParticipantsIn total, 1037 NHRs presenting to 17 EDs in France over 4 nonconsecutive weeks in 2016.MethodsFinite mixture models were fitted to longitudinal data on activities of daily living (ADL) scores before transfer (time 1), during hospitalization (time 2), and within 1 week after discharge (time 3) to identify groups of NHRs following similar functional evolution. Factors associated with mortality were investigated by Cox regressions.ResultsTrajectory modeling identified 4 distinct trajectories of ADL. The first showed a high and stable (across time 1, time 2, and time 3) functional capacity around 5.2/6 ADL points, with breathlessness as the main condition leading to transfer. The second displayed an initial 37.8% decrease in baseline ADL performance (between time 1 and time 2), followed by a 12.5% recovery of baseline ADL performance (time 2?time 3), with fractures as the main condition. The third displayed a similar initial decrease, followed by a 6.7% recovery. The fourth displayed an initial 70.1% decrease, followed by an 8.5% recover, with more complex geriatric polypathology situations. Functional decline was more likely after being transferred for a cerebrovascular condition or for a fracture, after being discharged from ED to a surgery department, and with a heavier burden of distressing symptoms during transfer. Mortality after ED transfer was more likely in older NHRs, those in a more severe condition, those who were hospitalized more frequently in the past month, and those transferred for cerebrovascular conditions or breathlessness.Conclusions and ImplicationsIdentified trajectories and factors associated with functional decline and mortality should help clinicians decide whether to transfer NHRs to ED. NHRs with high functional ability seem to benefit from ED transfers whereas on-site alternatives should be sought for those with poor functional ability.     

The Relationship Between Violence Syndemics and Sexual Risk Behaviors Among African American Adolescents: Implications for Future Research

PurposeWe present a conceptual framework based on a review of the literature to highlight the interconnecting and reinforcing elements of a violence syndemic and how this syndemic influences sexual risk behaviors among African American heterosexual adolescents.MethodsWe review existing peer-reviewed published research from 2000 to 2020 that links a violence syndemic (i.e., racism and race-related stress, neighborhood and police violence, peer violence, and family violence and disruptions) to adolescent sexual risk behaviors. Empirical findings and theoretical underpinnings are used to document this relationship and illuminate the factors that mediate this relationship.ResultsEmpirical studies support the links between specific types of violence and sexual risk behaviors among African American adolescents. Further, existing studies point to the important relationships among the specific types of violence, supporting a violence syndemic approach.ConclusionsWhile more researchers are examining socio-ecological contextual factors as important predictors for sexual risk behaviors, there remains inadequate understanding about how violence types reinforce one another to heighten sexual risk behaviors among African American heterosexual adolescents. This article presents new directions for adolescent research, especially how a violence syndemic approach can be used to explain sexual risk, but also to refocus intervention design on the complex burdens experienced by this population.     

Coping With Stress Through Texting: An Experimental Study

PurposeTexting is used by many adolescents and has the potential to improve well-being, as youth can reach out for support immediately after experiencing a stressful situation. Many studies have examined whether texting is associated with well-being, but few have used experimental designs, preventing causal claims.MethodsIn this experimental study, 130 adolescents (M_age = 12.41) participated with a same-gender friend whom they texted regularly. Both adolescents completed a task that elicited stress and then engaged in one of the following randomly assigned activities: texting their friend, watching a video on a cellphone (passive-phone condition), or sitting quietly (no activity condition). Participants reported their mood and stress levels after the stress task and again after the activity. Heart rate variability was measured throughout.ResultsParticipants who texted their friend reported higher moods (b = ?.80, standard error [SE] = .24, p < .001, η_p² = .09) and lower stress at the end of the study than those in the no activity condition (b = .51, SE = .25, p = .046, η_p² = .04) and higher moods than adolescents in the passive-phone condition (b = ?.74, SE = .25, p = .004, η_p² = .08). No differences were noted between the passive-phone and no activity conditions. There were no differences in heart rate variability between the three conditions. The effects of texting on mood, self-reported stress, and heart rate variability did not differ by gender.ConclusionsBoth boys and girls may benefit from texting a friend after experiencing a stressful event.     

A Cross-Country Network Analysis of Adolescent Resilience

PurposeIn situations of adversity, young people draw on individual, relational, and contextual (community and cultural) resources to foster their resilience. Recent literature defines resilience as a capacity that is underpinned by a network of interrelated resources. Although empirical studies show evidence of the value of a network approach, little is known regarding how different country contexts influence which resources are most critical within a resource network and how resources interact for adolescent resilience.MethodsNetwork analysis was conducted with data from studies that had used the Child and Youth Resilience Measure. Regularized partial correlation networks of 17 resources were estimated for 14 countries (Botswana, Canada, China, Colombia, Equatorial Guinea, India, Indonesia, Italy, Jordan, New Zealand, the Philippines, Romania, South Africa, and Syrian refugees living in Jordan). The sample size was 18,914 (mean age = 15.70 years, 48.8% female).ResultsWe observed mostly positive associations between the resources of interest. The salience and strength of associations between resources varied by country. The most central resource across countries was having supportive caregivers during stressful times because this resource had the most and strongest positive associations with other resources.ConclusionsThis study gives first empirical evidence from multiple countries that an interplay of social–ecological resources (such as individual skills, peer, caregiver and community support, and educational aspirations and opportunities) matter for adolescent resilience. Across countries, caregiver support appears to be most central for adolescent resilience. Future resilience interventions might apply this network approach to identify important, contextually relevant resources that likely foster additional resources.
