Examining Cross-Age Experiences in a Distance-Based Intergenerational Music Project: Comfort and Expectations in Collaborating With Opposite Generation Through “Virtual” Exchanges

There has been an increase in the number of music-based intergenerational programs conducted by music therapists as part of wellness and intergenerational music therapy programs. Research has shown that intergenerational music therapy programs have improved cross-age attitudes, interactions, and older adults' psychosocial well-being. Anecdotal evidence indicates that one of the challenges for creating music-based intergenerational programs is finding agencies that serve younger and older generations within close proximity to one another. We sought to remedy this problem with the integration of “virtual” technology. The purpose of this study was to examine changes in cross-age comfort, expectations after experiencing “virtual” exchanges, and preconceived notions of older and younger persons enrolled in a distance-based intergenerational project. A secondary purpose was to determine what intergenerational project factors were most enjoyable for older and younger participants. Eighteen older adults (61 through 79 years old) from an intact music-therapy choir along and 14 younger children from an intact community choir (9 through 14 years old) served as participants for the current study. All participants experienced the 4-week distance-based intergenerational program that consisted of: (a) two group “virtual” exchanges, (b) two reflective journals related to the “virtual” exchanges, (c) an in-person half-day music-therapy intergenerational workshop, and (d) a joint performance. Cross-age comfort, preconceived notions, expectations, and preference factors were examined through pre-test and post-test measurements. Results indicated an increase in older adults' comfort level collaborating with children after participation in the intergenerational music project. The majority of younger (64%) and older (69%) participants indicated that their preconceived notions about the other generation were different and positive from what they initially thought prior to the project. Both generations indicated an improvement in cross-age attitudes and interactions due to the collaboration process (“virtual” exchange, workshop, and joint-performance) and the cross-age interactions during the project. These findings suggest that music therapists can foster cross-age interactions and relationships between generations that are not within close proximity of one another by using a combination of “virtual” and “live” interactions as an intervention for enhancing the overall quality of life among older adults

Distinguishing Asthma Phenotypes Using Machine Learning Approaches.

Asthma is not a single disease, but an umbrella term for a number of distinct diseases, each of which are caused by a distinct underlying pathophysiological mechanism. These discrete disease entities are often labelled as asthma endotypes. The discovery of different asthma subtypes has moved from subjective approaches in which putative phenotypes are assigned by experts to data-driven ones which incorporate machine learning. This review focuses on the methodological developments of one such machine learning technique-latent class analysis-and how it has contributed to distinguishing asthma and wheezing subtypes in childhood. It also gives a clinical perspective, presenting the findings of studies from the past 5 years that used this approach. The identification of true asthma endotypes may be a crucial step towards understanding their distinct pathophysiological mechanisms, which could ultimately lead to more precise prevention strategies, identification of novel therapeutic targets and the development of effective personalized therapies

3D Printed Franz cells - update on optimization of manufacture and evaluation

The evaluation of permeation profiles from cosmetic formulations is considered to be a crucial component in both the development and quality assurance of any new product [1, 2]. Data gathered from such studies allow researchers to assess the viability of delivering different materials to and through biological membranes. To date, laboratory in vitro permeation processes require the use of modified Franz type diffusion cells, conventionally fabricated from glass, which are available in different formats that can be customised to experimental requirements [3]

3D-printed Franz cells - update on optimization of manufacture and evaluation

OBJECTIVES: Laboratory in vitro permeation processes require the use of modified Franz type diffusion cells which are conventionally fabricated from glass. Fragility and high cost are frequently associated with this type of laboratory apparatus. The purpose of our present research was to develop a simple, economical and versatile approach to manufacture Franz type cells using additive manufacturing (AM). METHODS: Graphical Franz diffusion cell designs were reproduced with a stereolithography (SLA) 3D printer and assessed over a minimum period of 24 h. The surface morphology of AM printouts was analysed before and after compatibility studies using scanning electron microscopy (SEM). Comparative permeation studies in both glass and AM Franz type diffusion cells were conducted using a caffeine solution (1.5 mg mL‑1), applied to a model silicone membrane. RESULTS: Testing of the 3D printed scaffolds confirmed similar recovery of the permeant when compared to glass cells: 1.49 ± 0.01 and 1.50 ± 0.01 mg mL‑1, respectively, after 72 h. No significant differences were visible from the SEM micrographs demonstrating consistent, smooth and non-porous surfaces of the AM Franz cells’ core structure. Permeation studies using transparent 3D printed constructs resulted in 12.85 ± 0.53 μg cm ‑2 caffeine recovery in the receptor solution after 180 min with comparable permeant recovery, 11.49 ± 1.04 μg cm ‑2, for the glass homologues. CONCLUSION: AM constructs can be considered as viable alternatives to the use of conventional glass apparatus offering a simple, reproducible and cost-effective method of replicating specialised laboratory glassware. A wider range of permeants will be investigated in future studies with these novel 3D printed Franz diffusion cells

The Social and Cultural Context of Coping with Sickle Cell Disease: I. A Review of Biomedical and Psychosocial Issues

Sickle cell disease (SCD) is widely conceived in the United States as a group of blood disorders that principally affect African Americans. Although pain is its principal feature, strokes, lung problems, sepsis, anxiety, depression, impaired social functioning, and maladjustment at work are frequent concomitants. This article selectively reviews biomedical and psychosocial aspects of SCD related to pain assessment, medical treatment, genetic counseling, education, and employment. The strongest support exists for claims of social deficits among adolescents and depression and work-related problems among adults. The social context of SCD, including issues related to socioeconomic status (SES), urbanicity, ethnicity, cultural values, and racial stigmatization, are important to include in empirical assessments and theoretical analyses of the effects of SCD on children and their families. The adverse psychosocial functioning often described as an effect of SCD might indeed be a consequence of these factors acting alone or in concert with the strains of SCD.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/67048/2/10.1177_0095798499025003002.pd

Intergenerational Communication – an interdisciplinary mapping review of research between 1996 and 2017

Concerns have been raised regarding the limited opportunities for intergenerational communication both outside and within the family. This “mapping review” draws together empirical literature in the topic published since 1996. Three hundred and twenty-four published studies met inclusion criteria, based on abstract review. The contents of each study were subjected to thematic analysis and nine broad themes emerged. These were (1) Dynamics of relationships, (2) Health & Well-being, (3) Learning & Literacy, (4) Attitudes, (5) Culture, (6) Digital, (7) Space, (8) Professional Development, and (9) Gender & Sexual Orientation. Studies commonly intersected disciplinary research areas. There was a marked rise across three key academic journals since 2007. An emergent finding was that a third of the studies relate to programs addressing intergenerational interventions, but many of these were primarily descriptive and failed to specify a primary outcome. Review implications and future research directions are discussed

Native American Children and Their Reports of Hope: Construct Validation of the Children's Hope Scale

Child reports of hope continue to be utilized as predictors of positive adjustment; however, the utilization of the hope construct has not been assessed within the culturally diverse Native American child group. The present study investigated the applicability of the Hope theory among 96 Native American children in the Midwest. Measures included the Children’s Hope Scale and a Hope Interview. Native American children in the current sample appear to conceptualize hope as a way to reach goals as did the children in the normative sample. Results from the factor analysis demonstrate that the factor structure found in the current study was similar to the factor structure found in the standardization sample. Because of the similar Hope theory conceptualization and factor structure, interventions focused on the positive psychology construct of hope may be applicable within a Native American child population

Trajectories of childhood immune development and respiratory health relevant to asthma and allergy.

Events in early life contribute to subsequent risk of asthma; however, the causes and trajectories of childhood wheeze are heterogeneous and do not always result in asthma. Similarly, not all atopic individuals develop wheeze, and vice versa. The reasons for these differences are unclear. Using unsupervised model-based cluster analysis, we identified latent clusters within a prospective birth cohort with deep immunological and respiratory phenotyping. We characterised each cluster in terms of immunological profile and disease risk, and replicated our results in external cohorts from the UK and USA. We discovered three distinct trajectories, one of which is a high-risk 'atopic' cluster with increased propensity for allergic diseases throughout childhood. Atopy contributes varyingly to later wheeze depending on cluster membership. Our findings demonstrate the utility of unsupervised analysis in elucidating heterogeneity in asthma pathogenesis and provide a foundation for improving management and prevention of childhood asthma
