Increased Risk of Infection in Bereaved Older Adults: From Broken Heart to Broken Immune System

Testing bidirectional relationships between marital quality and sleep disturbances: A 4-year follow-up study in a Korean cohort

Integrative approaches in the primary care setting have grown in favor over the past few decades, with many interesting findings about the influence of personality disorders on physical health and functioning; however, less is known about how specific pathological personality traits impact patient-provider assessments of physical and mental health. Using the DSM-5 Levels of Personality Functioning Questionnaire-Short Form (DLOPFQ-SF) and Personality Inventory for DSM-5-Brief Form, these relationships were evaluated in a sample of 50 inner-city, low-income patients in a primary care clinic. Point-biserial correlations revealed significant correlations between physical and mental health morbidities, as well as personality pathology and patient response to treatment. Our findings lend further support to describing the relationships between personality pathology, medical comorbidities, and patient response to treatment.

Young adults in the general population are at risk of experiencing loneliness, which has been associated with physical and mental health morbidities. The prevalence and consequences of loneliness in young adult survivors of childhood cancer remain unknown. A total of 9664 young adult survivors of childhood cancer (median age at diagnosis 10.5years [interquartile range (IQR), 5-15], 27.1years at baseline [IQR, 23-32]) and 2221 siblings enrolled in the Childhood Cancer Survivor Study completed a self-reported survey question assessing loneliness on the Brief Symptom Inventory-18 at baseline and follow-up (median follow-up, 6.6years). Multivariable models evaluated the prevalence of loneliness at baseline only, follow-up only, and baseline+follow-up, and its associations with emotional distress, health behaviors, and chronic conditions at follow-up. Survivors were more likely than siblings to report loneliness at baseline+follow-up (prevalence ratio [PR] 2.2; 95% confidence interval [CI], 1.7-3.0) and at follow-up only (PR, 1.4; 95% CI, 1.1-1.7). Loneliness at baseline+follow-up was associated with elevated risk of anxiety (relative risk [RR], 9.8; 95% CI, 7.5-12.7), depression (RR, 17.9; 95% CI, 14.1-22.7), and current smoking (odds ratio [OR], 1.7; 95% CI, 1.3-2.3) at follow-up. Loneliness at follow-up only was associated with suicidal ideation (RR, 1.5; 95% CI, 1.1-2.1), heavy/risky alcohol consumption (RR, 1.3; 95% CI, 1.1-1.5), and new-onset grade 2-4 chronic conditions (RR, 1.3; 95% CI, 1.0-1.7). Young adult survivors of childhood cancer have elevated risk of experiencing loneliness, which is associated with future emotional distress, risky health behaviors, and new-onset chronic conditions.

Family carers of people who have long term illness often experience physical and mental health morbidities, and burden. While there is good evidence to suggest that carers benefit from psychosocial interventions, these have primarily been delivered via face-to-face individual or group-formats. eHealth interventions offer a novel, accessible and self-paced approach to care delivery. Whether these are effective for carers' wellbeing has been little explored. This paper reports the first comprehensive systematic review in this area. A total of 78 studies, describing 62 discrete interventions, were identified. Interventions commonly aimed to promote carers' knowledge, self-efficacy, caregiving appraisal, and reduce global health morbidities. Interventions were offered to carers of people with a wide range of long term illness; dementia has been the most researched area, as reported in 40% of studies. Clinical and methodological heterogeneity in interventions precluded meta-analyses, and so data were analysed narratively. The most popular approach has comprised psychoeducational interventions delivered via an enriched online environment with supplementary modes of communication, such as network support with professionals and peers. Overall, carers appreciate the flexibility and self-paced nature of eHealth interventions, with high rates of satisfaction and acceptability. More studies using robust designs are needed to extend the evidence base.

Understanding gender-based violence perpetration to create a safer future for women and girls.

Longitudinal variations in maximal oxygen intake with age and activity.

Advancing age is commonly associated with changes in both brain structure and function. Recently, the suggestion that alterations in brain connectivity may drive disruption in cognitive abilities with age has been investigated. However, the interaction between the effects of age and gender on the re-organization of resting-state networks is not fully understood. This study sought to investigate the effect of both age and gender on intra- and inter-network functional connectivity (FC) and the extent to which resting-state network (RSN) node definition may alter with older age. We obtained resting-state functional magnetic resonance images from younger (n = 20) and older (n = 20) adults and assessed the FC of three main cortical networks: default mode (DMN), dorsal attention (DAN), and saliency (SN). Older adults exhibited reduced DMN intra-network FC and increased inter-network FC between the anterior cingulate cortex (ACC) and nodes of the DAN, in comparison to younger participants. Furthermore, this increase in ACC-DAN inter-network FC with age was driven largely by male participants. However, further analyses suggested that the spatial location of ACC, bilateral anterior insula and orbitofrontal cortex RSN nodes changed with older age and that age-related gender differences in FC may reflect spatial re-organization rather than increases or decreases in FC strength alone. These differences in both the FC and spatial distribution of RSNs between younger and older adults provide evidence of re-organization of fundamental brain networks with age, which is modulated by gender. These results highlight the need to further investigate changes in both intra- and inter-network FC with age, whilst also exploring the modifying effect of gender. They also emphasize the difficulties in directly comparing the FC of RSN nodes between groups and suggest that caution should be taken when using the same RSN node definitions for different age or patient groups to investigate FC.

The aim was to evaluate the use of an internal strategy (i.e., subjective organization) in relation to physical activity (PA) level in older adults. We expected (1) an effect of age on memory performance and subjective organization, in favor of younger adults, and (2) an association between PA and memory performance and between PA and organization index, particularly in older adults. Forty-five younger (M = 27.58 yo) and 45 older adults (M = 71.49 yo) learned a list of 19 semantically unrelated concrete nouns and took three consecutive recalls. An index was calculated from the order in which the words were recalled (pairwise frequency index, PFI). Participants reported their PA over the past year. Three General Linear Models were conducted to examine: (1) the effect of age and PFI on memory, (2) the effect of age and PA on memory, and (3) the effect of age and PA on PFI. Mediation analyses tested whether subjective organization (PFI) mediated the relationship between PA and memory recall. Younger adults recalled more words and used more subjective organization than older adults. In both age groups, those with better memory performance also used more subjective organization. Positive correlations were found between PA and memory performance in both younger and older adults, and between PA and subjective organization only in older adults. The mediation analysis revealed that PA's effect on memory was partially mediated by subjective organization, explaining 39% of the effect. The present study revealed that higher PA level in older adults was associated with increased recall and use of subjective organization strategy, addressing a gap in understanding the benefits of PA on memory during aging. The results are discussed in terms of the possible implication of executive functions, particularly for their role in implementing effective memory strategies during encoding.

Effects of age and sex on fatigability and recovery from a sustained maximal isometric voluntary contraction

Time of day (TOD) influences on executive functions have been widely reported, with greater efficiency demonstrated at optimal relative to non-optimal TOD according to one’s chronotype (i.e., synchrony effect). Older adults (OAs) show declines in inhibitory control and are more sensitive to the effects of circadian variation on executive functioning. To date, no studies have investigated the effects of TOD and aging on executive functioning using electrophysiological measures. The present study investigated the effects of aging and TOD on the neural correlates of inhibitory processing (N2 and P3) using event-related potentials (ERPs). Go-NoGo and Flanker tasks were administered to 52 OAs of morning chronotype and 51 younger adults (YAs) of afternoon-to-evening chronotype who were randomly assigned to morning or afternoon test sessions, with the optimal TOD for OAs in the morning and for YAs in the afternoon/evening. While behavioral results demonstrated no TOD effects, ERPs indicated synchrony effects. Both YAs and OAs showed greater modulation of Go-NoGo N2 and greater P3 amplitude during the non-optimal than optimal TOD, consistent with the synchrony effect. For the Flanker task, age differences in P3 amplitude were only apparent during the non-optimal TOD. These results suggest that processes associated with inhibitory control are differentially affected by TOD and aging, with age-related reductions in inhibitory efficiency during off-peak test times on measures of interference control. These findings highlight the sensitivity of ERPs to detect TOD effects in the absence of behavioral differences, confirm more pronounced TOD effects in OAs relative to YAs on ERP measures of interference control, and reinforce the need to assess and control for circadian typology in research studies.

ObjectivesFinancial decision-making (FDM) is crucial for independent living. Due to cognitive decline that accompanies normal aging, older adults might have difficulties in some aspects of FDM. However, an improved knowledge, personal experience and affective decision-making, which are also related to normal aging, may lead to a stable or even improved age-related performance in some other aspects of FDM. Therefore, the present explorative study examines the effects of normal aging on multiple aspects of FDM.MethodsOne-hundred and eighty participants (range 18–87 years) were assessed with eight FDM tests and several standard neuropsychological tests. Age effects were evaluated using hierarchical multiple regression analyses. The validity of the prediction models was examined by internal validation (i.e. bootstrap resampling procedure) as well as external validation on another, independent, sample of participants (n = 124). Multiple regression and correlation analyses were applied to investigate the mediation effect of standard measures of cognition on the observed effects of age on FDM.ResultsOn a relatively basic level of FDM (e.g., paying bills or using FDM styles) no significant effects of aging were found. However more complex FDM, such as making decisions in accordance with specific rules, becomes more difficult with advancing age. Furthermore, an older age was found to be related to a decreased sensitivity for impulsive buying. These results were confirmed by the internal and external validation analyses. Mediation effects of numeracy and planning were found to explain parts of the association between one aspect of FDM (i.e. Competence in decision rules) and age; however, these cognitive domains were not able to completely explain the relation between age and FDM.ConclusionNormal aging has a negative influence on a complex aspect of FDM, however, other aspects appear to be unaffected by normal aging or improve.

Texting while walking (TeWW) has become common among people of all ages, and mobile phone use during gait is increasingly associated with pedestrian injury. Although dual-task walking performance is known to decline with age, data regarding the effect of age on dual-task performance in ecological settings are limited. The objective of this study was to evaluate the effect of age, environment (indoors/outdoors), and mixed reality (merging of real and virtual environments) on TeWW performance. A cross-sectional design was used. Young (n=30; 27.8±4.4 years) and older (n=20; 68.9±3.9 years) adults performed single- and dual-task texting and walking indoors and outdoors, with and without a mixed reality display. Participants also completed evaluations of visual scanning and cognitive flexibility (Trail Making Test) and functional mobility (Timed "Up & Go" Test). Indoors, similar interference to walking and texting occurred for both groups, but only older adults' gait variability increased under dual task conditions. Outdoors, TeWW was associated with larger age-related differences in gait variability, texting accuracy, and gait dual-task costs. Young adults with better visual scanning and cognitive flexibility performed TeWW with lower gait costs (r=0.52-0.65). The mixed reality display was unhelpful and did not modify walking or texting. Older adults tested in this study were relatively high functioning. Gaze of participants was not directly monitored. Although young and older adults possess the resources necessary for TeWW, older adults pay an additional "price" when dual-tasking, especially outdoors. TeWW may have potential as an ecologically valid assessment and/or an intervention paradigm for dual-task performance among older adults as well as for clinical populations.

The aging Chinese population is growing fast, and the proportion of the population aged 60 years old is projected to reach 28% by 2040, estimated 402 million. With increased life expectancy, the aging population tends to suffer from health risks and diseases, which create a burden on public health policy. Hence, it is essential to promote healthy and active aging, which includes improving older adults' physical and mental capacities and advocating for the achievement of a healthy life expectancy. Despite the rapidly growing aging population in China, there have been no reviews investigating the effect of physical activity on physical and mental health among older Chinese adults. Therefore, the current study aimed to review studies from the past 15 years that illustrate the effect of physical activity on physical and mental health among Chinese older adults. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews (PRISMA-ScR), this review addresses the associations between physical activity, physical health and mental health among older Chinese adults. A total of 371 studies were included in the scoping review, which covered the relationships between physical activity, physical health and mental health variables. The scoping review also revealed the impact of various kinds of physical activity affecting older adults' physical health, such as functional fitness, body composition, fall risk and balance, and mental health issues, such as depression, anxiety, cognitive function and quality of life. Moreover, studies have identified innovative forms of physical activity as emerging trends in physical activity interventions for older adults. To conclude, this scoping review captured the common effects between physical activity and overall wellbeing, including physical, mental, and cognitive health. Additionally, diverse forms of physical activity intervention, such as group-based and supervised individual interventions, should be supported, and cross-cultural exercise comparisons should be made in future explorations.

Intense inspiratory muscle work evokes a sympathetically mediated pressor reflex, termed the respiratory muscle metaboreflex, in which young females demonstrate an attenuated response relative to males. However, the effects of ageing and female sex hormones on the respiratory muscle metaboreflex are unclear. We tested the hypothesis that the pressor response to inspiratory work would be similar between older males and females, and higher relative to their younger counterparts. Healthy, normotensive young (26±3years) males (YM; n=10) and females (YF; n=10), as well as older (64±5years) males (OM; n=10) and females (OF; n=10), performed inspiratory pressure threshold loading (PTL) to task failure. Older adults had a greater mean arterial pressure (MAP) response to PTL than young (P<0.001). YF had a lower MAP compared to YM (+10±6 vs. +19±15mmHg, P=0.026); however, there was no difference observed between OF and OM (+26±11 vs. +27±11mmHg, P=0.162). Older adults had a lower heart rate response to PTL than young (P=0.002). There was no effect of sex between young females and males (+19±9 and +27±11bpm, P=0.186) or older females and males (+17±7 and +20±7bpm, P=0.753). We conclude the respiratory muscle metaboreflex response is heightened in older adults, and the sex effect between older males and post-menopause females is absent, suggesting an effect of circulating sex hormones. KEY POINTS: The arterial blood pressure response to the respiratory muscle metaboreflex is greater in older males and females. Compared to sex-matched young individuals, there is no sex differences in the blood pressure response between older males and post-menopause females. Our results suggest the differences between males and females in the cardiovascular response to high levels of inspiratory muscle work is abolished with reduced circulating female sex hormones.
