Meta-analytic evidence that attachment insecurity is associated with less frequent experiences of discrete positive emotions.

OBJECTIVE: Individual differences in attachment insecurity can have important implications for experiences of positive emotions. However, existing research on the link between attachment insecurity and positive emotional experiences has typically used a composite measure of positive emotions, overlooking the potential importance of differentiating discrete emotions. METHOD: We conducted a meta-analysis of 10 cross-sectional samples (N = 3215), examining how attachment insecurity is associated with self-reported frequency of experiencing positive emotions, with a distinction made between more social (i.e., love and gratitude) and less social (i.e., peace and awe or curiosity) positive emotions. RESULTS: High (vs. low) levels of both attachment anxiety and avoidance were associated with less frequent experience of positive emotions regardless of their social relevance. When analyzing each emotion separately, we found that attachment anxiety showed negative relations to all emotions except gratitude. Attachment avoidance was negatively associated with all emotions, and the link was even stronger with love (vs. peace, awe, or curiosity). Additional analyses of daily diary data revealed that attachment anxiety and avoidance were also negatively associated with daily experiences of positive emotions, regardless of social relevance. CONCLUSION: Our results underscore the need to further investigate the mechanisms underlying insecure individuals' blunted positive emotional experiences.

Using Virtual Reality to Improve the Quality of Life of Older Adults with Cognitive Impairments and their Family Members who Live at a Distance.

This study examines whether using virtual reality (VR) with older adults with mild cognitive impairment (MCI) or mild to moderate dementia with a family member who lives at a distance can improve the quality of life of the older adult and the family member. Twenty-one older adults in a senior living community and a family member (who participated in the VR with the older adult from a distance) engaged in a baseline telephone call, followed by three weekly VR sessions. The VR was associated with improvements in older adults' affect and stress, relationship with their family member, and overall quality of life, compared to baseline. Family members' negative affect, depressive symptoms, and caregiver burden also decreased and their mental health improved after using the VR, compared to baseline. Using the VR, however, did not change their relationship with the older adult. In addition, older adults and family members who experienced the VR sessions as more socially engaging reported better psychological and relational well-being, with older adults also experiencing greater improvements in overall quality of life. Finally, preliminary results suggest that older adults with dementia and their family members might benefit even more from using the VR than older adults with MCI and their family members.

Is Empathic Accuracy Enough to Facilitate Responsive Behavior in Dyadic Interaction? Distinguishing Ability From Motivation.

Growing evidence suggests that interpersonal responsiveness-feeling understood, validated, and cared for by other people-plays a key role in shaping the quality of one's social interactions and relationships. But what enables people to be interpersonally responsive to others? In the current study, we argued that responsiveness requires not only accurate understanding but also compassionate motivation. Specifically, we hypothesized that understanding another person's thoughts and feelings (empathic accuracy) would foster responsive behavior only when paired with benevolent motivation (empathic concern). To test this idea, we asked couples (N = 91) to discuss a personal or relationship stressor; we then assessed empathic accuracy, empathic concern, and responsive behavior. As predicted, when listeners' empathic concern was high, empathic accuracy facilitated responsiveness; but when empathic concern was low, empathic accuracy was unhelpful (and possibly harmful) for responsiveness. These findings provide the first evidence that cognitive and affective forms of empathy work together to facilitate responsive behavior.

A new look at social support: a theoretical perspective on thriving through relationships.

Close and caring relationships are undeniably linked to health and well-being at all stages in the life span. Yet the specific pathways through which close relationships promote optimal well-being are not well understood. In this article, we present a model of thriving through relationships to provide a theoretical foundation for identifying the specific interpersonal processes that underlie the effects of close relationships on thriving. This model highlights two life contexts through which people may potentially thrive (coping successfully with life's adversities and actively pursuing life opportunities for growth and development), it proposes two relational support functions that are fundamental to the experience of thriving in each life context, and it identifies mediators through which relational support is likely to have long-term effects on thriving. This perspective highlights the need for researchers to take a new look at social support by conceptualizing it as an interpersonal process with a focus on thriving.

Prevention and Treatment of Malnutrition in Older Adults Living in Long-Term Care or the Community: An Evidence-Based Nutrition Practice Guideline.

Malnutrition in older adults can decrease quality of life and increase risk of morbidities and mortality. Accurate and timely identification of malnutrition, as well as subsequent implementation of effective interventions, are essential to decrease poor outcomes associated with malnutrition in older adults. The Academy of Nutrition and Dietetics Evidence Analysis Center conducted a systematic review of the literature to develop an evidence-based nutrition practice guideline for the prevention and treatment of malnutrition in older adults. The objective of this guideline was to provide evidence-based recommendations to identify, prevent, or treat protein-energy malnutrition in older adults (mean age ≥65 years) living in long-term care and community settings. This guideline provides 11 nutrition recommendations to inform shared decision making among dietitians, members of the health care team, family members or caregivers, and older adults living in long-term care or the community to prevent or treat malnutrition. Topics include dietitian effectiveness, nutrition assessment tools, oral nutrition supplements, food fortification, and home-delivered and congregate meals. Guideline implementation should include consideration of the importance of comprehensive individualized nutrition care for older adults. Future research is needed to address gaps that were identified related to the validity, reliability, and feasibility of nutrition assessment tools, as well as the effectiveness of dietitian interventions on outcomes of interest in older adults living in long-term care and the community.

Motivations for providing a secure base: links with attachment orientation and secure base support behavior.

This investigation examined the importance of underlying motivations in predicting secure base support behavior, as well as the extent to which support motivations are predicted by individual differences in attachment orientation. Participants were 189 married couples who participated in two laboratory sessions. During a questionnaire session, couples completed assessments of their underlying motivations for providing, and for not providing, support for their partner's exploration (i.e., goal-strivings), as well as assessments of their typical secure base support behavior. In an observational session, couples engaged in a discussion of one member's personal goals, during which the partner's secure base support was assessed. Results revealed a variety of distinct motivations for providing, and for not providing, secure base support to one's partner, as well as theoretically expected links between these motivations and both secure base behavior and attachment orientation. This work establishes motivations as important mechanisms that underlie the effective or ineffective provision of relational support.

Cognitive Training with Neurofeedback Using fNIRS Improves Cognitive Function in Older Adults.

This study examined the effects of a 4-week cognitive training program with neurofeedback (CT-NF) among 86 healthy adults (M = 66.34 years, range 54-84) randomized to either a treatment (app-based ABC games) or control (Tetris) group. Participants completed seven cognitive assessments, pre- and post-intervention, and measured their cortical brain activity using a XB-01 functional near-infrared spectroscopy (fNIRS) brain sensor, while engaging in CT-NF. The treatment (ABC) group showed significant (pre/post-intervention) improvements in memory (MEM), verbal memory (VBM), and composite cognitive function, while the control group did not. However, both groups showed significant improvements in processing speed (PS) and executive function (EF). In line with other studies, we found that strength of cortical brain activity (measured during CT-NF) was associated with both cognitive (pre and post) and game performance. In sum, our findings suggest that CT-NF and specifically ABC exercises, confer improved cognition in the domains of MEM, VBM, PS, and EF.

Sleep, Emotions, and Sense of Belonging: A Daily Experience Study.

Sleep has strong influences on affective and social experiences. However, less is known about the reciprocal effects of sleep, affect, and social experiences at a daily level, and little work has considered racial/ethnic minorities at high risk for social disconnection and discrimination. A 7-day daily experience study assessed the bidirectional relationships between daily sleep quality, affect, social experiences, and overall well-being among a sample of Latinx undergraduates (N = 109). Each morning, participants reported on their previous night's sleep. Each evening, they reported their positive and negative affect, experiences of belonging and unfair treatment, and overall well-being that day. Results indicate that, at a daily level, sleep quality predicts next-day affect, belonging, and well-being. Reciprocally, only daily well-being predicts sleep quality. Findings highlight sleep as a potentially powerful antecedent of affective and social experiences likely to be particularly potent for underrepresented minority groups.

T cell-depleted unrelated donor stem cell transplantation provides favorable disease-free survival for adults with hematologic malignancies.

We report a prospective phase II clinical trial in 35 adult patients (median age 40.5 years) with hematologic malignancies who received T cell-depleted, hematopoietic stem cell transplants from HLA-compatible, unrelated donors. The cytoreductive regimen consisted of hyperfractionated total-body irradiation, thiotepa, and fludarabine. The preferred graft source was granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood stem cells (PBSC). PBSC were CD34(+) selected, followed by sheep erythrocyte rosetting to deplete residual T cells. Anti-thymocyte globulin provided graft rejection prophylaxis. No additional graft-versus-host disease (GVHD) prophylaxis was planned. Estimated disease-free survival at 4 years is 56.8% for the entire group and 75% in patients with standard-risk disease. The cumulative incidence of relapse is 6%. Acute GVHD grade II-III developed in 9% and chronic GVHD in 29% of patients. Fatal infections occurred in 5 of 35 (14%) patients. There was 1 late graft failure. This study demonstrates durable engraftment with a low overall incidence of GVHD. Its curative potential is reflected in the remarkably low relapse rate at 4 years.

Distinct responses of human monocyte subsets to Aspergillus fumigatus conidia.

Aspergillus fumigatus is an environmental fungus that causes life-threatening infections in neutropenic patients. In the absence of intact innate immunity, inhaled A. fumigatus spores (conidia) germinate in the lung, forming hyphae that invade blood vessels and disseminate to other tissues. Although macrophages and neutrophils are postulated to provide defense against invasive fungal infection, animal models and human studies suggest that circulating monocytes also contribute to antifungal immunity. Although human monocyte subsets, defined as either CD14(+)CD16(-) or CD14(+)CD16(+), have been extensively characterized, their respective roles during fungal infection remain undefined. We isolated CD14(+)CD16(-) and CD14(+)CD16(+) monocytes from healthy allogeneic hematopoietic stem cell transplantation donors and compared their ability to phagocytose and inhibit A. fumigatus conidia. Both monocyte subsets efficiently phagocytose conidia, but only CD14(+)CD16(-) monocytes inhibit conidial germination yet secrete little TNF. In contrast CD14(+)CD16(+) do not inhibit conidial germination and secrete large amounts of TNF. Although CD14(+)CD16(-) and CD14(+)CD16(+) monocytes differ in their response to dormant conidia, responses are similar if conidia are already germinated at the time of monocyte uptake. Our study demonstrates that functional CD14(+)CD16(-) and CD14(+)CD16(+) monocytes can be isolated from allogeneic hematopoietic stem cell transplantation donors and that these subsets differ in their response to A. fumigatus conidia.

Testing the Feasibility of Virtual Reality With Older Adults With Cognitive Impairments and Their Family Members Who Live at a Distance.

BACKGROUND AND OBJECTIVES: This study tests the feasibility of using virtual reality (VR) with older adults with mild cognitive impairment (MCI) or mild-to-moderate dementia with a family member who lives at a distance. RESEARCH DESIGN AND METHODS: 21 residents in a senior living community and a family member (who participated in the VR with the older adult from a distance) engaged in a baseline telephone call, followed by 3 weekly VR sessions. RESULTS: Residents and family members alike found the VR safe, extremely enjoyable, and easy to use. The VR was also acceptable and highly satisfying for residents with MCI and dementia. Human and automated coding revealed that residents were more conversationally and behaviorally engaged with their family member in the VR sessions compared to the baseline telephone call and in the VR sessions that used reminiscence therapy. The results also illustrate the importance of using multiple methods to assess engagement. Residents with dementia reported greater immersion in the VR than residents with MCI. However, the automated coding indicated that residents with MCI were more kinesically engaged while using the VR than residents with dementia. DISCUSSION AND IMPLICATIONS: Combining networking and livestreaming features in a single VR platform can allow older adults in senior living communities to still travel, relive their past, and engage fully with life with their family members, despite geographical separation and physical and cognitive challenges.

A new CAM6 + DART reanalysis with surface forcing from CAM6 to other CESM models.

An ensemble Kalman filter reanalysis has been archived in the Research Data Archive at the National Center for Atmospheric Research. It used a CAM6 configuration of the Community Earth System Model (CESM), several million observations per day, and the Data Assimilation Research Testbed (DART). The data saved from this global, [Formula: see text] resolution, 80 member ensemble span 2011-2019. They include ensembles of: sub-daily, real world, atmospheric forcing for use by all of the nonatmospheric models of CESM; weekly, CAM6, restart file sets; 6 hourly, prior hindcast estimates of the assimilated observations; 6 hourly, land model, plant growth variables, and 6 hourly, ensemble mean, gridded, atmospheric analyses. This data can be used for hindcast studies and data assimilation using component models of CESM; CAM6, CLM5, CICE5, POP2. MOM6, MOSART, and CISM; and non-CESM Earth system models. This large dataset (~ 120 Tb) has a unique combination of a large ensemble, high frequency, and multiyear time span, which provides opportunities for robust statistical analysis and use as a machine learning training dataset.

The effect of the composition of unrelated donor bone marrow and peripheral blood progenitor cell grafts on transplantation outcomes.

To test the hypothesis that the outcome of hematopoietic stem cell (HSC) grafts is at least partially determined by the cellular composition of the graft, the National Marrow Donor Program (NMDP) analyzed the correlation of cellular phenotypes of unrelated grafts with graft outcome. Samples from 94 bone marrow (BM) and 181 peripheral blood progenitor cell (PBPC) grafts for transplantations at 40 U.S. transplant centers between 2003 and 2005 were analyzed at a single immunophenotyping reference laboratory. Samples were shipped from transplant centers upon receipt of graft. Graft cellular composition included analysis of leukocyte total cell numbers, and subsets of myeloid [CD34(+), CD34(+) CD38(-)], lymphoid [CD3(+), CD3(+) CD4(+), CD3(+) CD8(+)], and activated lymphoid cells [CD3(+) CD25(+), CD3(+) CD69(+), CD3(+) HLA-DR(+)] coexpressing CD3(+). There was substantial variability in the cellular composition of BM and PBPC grafts before and after graft processing by red blood cell (RBC) removal or plasma depletion in preparation for transplant. With BM grafts, cellular composition was not associated with hematopoietic recovery, graft-versus-host disease (GVHD), or survival. With PBPC grafts, survival rates were higher with CD34(+)>5 x 10(6)/kg, 59% compared to 34% with CD34(+)< or =5 x 10(6)/kg at 1 year. Platelet recovery was higher with PBPC containing CD3(+) CD8(+) >8 x 10(7)/kg. Neutrophil recovery or GVHD could not be predicted by any cellular subsets of PBPC grafts. Although survival was superior with PBPC grafts containing >5 x 10(6) CD34(+)/kg, an optimal graft mix of myeloid, lymphoid, and activated lymphoid subsets was not identified.

After the Honeymoon: Neural and Genetic Correlates of Romantic Love in Newlywed Marriages.

In Western culture, romantic love is commonly a basis for marriage. Although it is associated with relationship satisfaction, stability, and individual well-being, many couples experience declines in romantic love. In newlyweds, specifically, changes in love predict marital outcomes. However, the biological mechanisms underlying the critical transition to marriage are unknown. Thus, for the first time, we explored the neural and genetic correlates of romantic love in newlyweds. Nineteen first-time newlyweds were scanned (with functional MRI) while viewing face images of the partner versus a familiar acquaintance, around the time of the wedding (T1) and 1 year after (T2). They also provided saliva samples for genetic analysis (AVPR1a rs3, OXTR rs53576, COMT rs4680, and DRD4-7R), and completed self-report measures of relationship quality including the Eros (romantic love) scale. We hypothesized that romantic love is a developed form of the mammalian drive to find, and keep, preferred mates; and that its maintenance is orchestrated by the brain's reward system. Results showed that, at both time points, romantic love maintenance (Eros difference score: T2-T1) was associated with activation of the dopamine-rich substantia nigra in response to face images of the partner. Interactions with vasopressin, oxytocin, and dopamine genes implicated in pair-bonding (AVPR1a rs3, OXTR rs53576, COMT rs4680, and DRD4-7R) also conferred strong activation in the dopamine-rich ventral tegmental area at both time points. Consistent with work highlighting the role of sexual intimacy in relationships, romantic love maintenance showed correlations in the paracentral lobule (genital region) and cortical areas involved in sensory and cognitive processing (occipital, angular gyrus, insular cortex). These findings suggest that romantic love, and its maintenance, are orchestrated by dopamine-, vasopressin- and oxytocin-rich brain regions, as seen in humans and other monogamous animals. We also provide genetic evidence of polymorphisms associated with oxytocin, vasopressin and dopamine function that affect the propensity to sustain romantic love in early stage marriages. We conclude that romantic love maintenance is part of a broad mammalian strategy for reproduction and long-term attachment that is influenced by basic reward circuitry, complex cognitive processes, and genetic factors.

The importance of relational support for attachment and exploration needs.

In this article, we discuss theory and research on social support and caregiving processes in adult close relationships. We first outline key theoretical principles of attachment theory and of a theoretical perspective on thriving through relationships that builds on attachment theory. We then review empirical research that has tested key theoretical postulates regarding the importance of relational support for both attachment and exploration needs. The empirical review is divided into two components that reflect the two major functions of support/caregiving in close relationships, and that reflect the two different life contexts in which relational support/care is crucial (support in adversity and support for exploration and pursuit of opportunities). We conclude by emphasizing important directions for future research.

Close Relationships and Health: The Interactive Effect of Positive and Negative Aspects.

Most health research focuses on the independent associations of positive or negative aspects of close relationships with health outcomes. A small but growing literature has begun to examine interactive effects of positive and negative aspects. These interactive effects frequently predict health independently or above-and-beyond main effects of either the positive or the negative aspects, suggesting unique relationship processes or emergent features of these close relationship patterns. Our goal in this review is to lay out the existing approaches to studying the interactive effects of positive and negative aspects of close relationships, and to review available evidence linking these interactive effects to health outcomes. We conclude by discussing important unresolved issues and highlighting critical directions for future research.

Transplantation in remission improves the disease-free survival of patients with advanced myelodysplastic syndromes treated with myeloablative T cell-depleted stem cell transplants from HLA-identical siblings.

From 1985 to 2004, 49 patients with advanced myelodysplastic syndromes (MDS) (> or =5% blasts) or acute myeloid leukemia (AML) transformed from MDS underwent T cell depleted bone marrow or peripheral blood hematopoietic stem cell transplantation (HSCT) from HLA-identical siblings following conditioning with a myeloablative regimen that included total body irradiation (44 patients) or busulfan (5 patients). Thirty-six patients received chemotherapy (3 low dose and 33 induction doses) before conditioning, and 13 patients did not receive any chemotherapy. Prior to transplantation, 22 of the 36 treated patients were in hematologic remission; 4 were in a second refractory cytopenia phase (26 responders); 8 had failed to achieve remission; and 2 of the responders had progression or relapse of their MDS (10 failures). No post-transplantation pharmacologic prophylaxis for graft-versus-host disease (GVHD) was given. The median age was 48 yrs (range 13-61). Forty-five of the 49 patients engrafted; 2 had primary graft failure; and 2 died before engraftment. Only 3 patients developed acute GVHD (aGVHD) (grades I and III) and 1 chronic GVHD (cGVHD). At 3 yrs post-transplantation, the overall survival (OS) was 54% in the responders; 31% in the untreated group; and 0% in the failure group (P=.0004). The disease free survival (DFS) was 50%, 15% and 0% in each group respectively (P=.0008). In multivariate analysis, disease status before cytoreduction remained highly correlated with DFS (P<.001). The cumulative incidence (CI) of relapse at 2-yrs post-transplantation for the responders was 23%; for the untreated group was 38%; and for the failures was 50%. The CI of non-relapse mortality at 2-yrs post-transplantation, for the responders was 23%; for the untreated group was 38%; and for the failures was 40%. All survivors achieved a Karnofsky Performance Status (KPS) of > or =90. These results indicate that patients with advanced MDS who achieve and remain in remission or a second refractory cytopenia phase with chemotherapy before conditioning can achieve successful long-term remissions following a myeloablative T cell depleted allogeneic HSCT.
