The value of active arts engagement on health and well-being of older adults: a nation-wide participatory study

An emerging body of research indicates that active arts engagement can enhance older adults' health and experienced well-being, but scientific evidence is still fragmented. There is a research gap in understanding arts engagement grounded in a multidimensional conceptualization of the value of health and well-being from older participants' perspectives. This Dutch nation-wide study aimed to explore the broader value of arts engagement on older people's perceived health and well-being in 18 participatory arts-based projects (dance, music, singing, theater, visual arts, video, and spoken word) for community-dwelling older adults and those living in long term care facilities. In this study, we followed a participatory design with narrative- and arts-based inquiry. We gathered micro-narratives from older people and their (in)formal caregivers (n = 470). The findings demonstrate that arts engagement, according to participants, resulted in (1) positive feelings, (2) personal and artistic growth, and (3) increased meaningful social interactions. This study concludes that art-based practices promote older people's experienced well-being and increase the quality of life of older people. This study emphasizes the intrinsic value of arts engagement and has implications for research and evaluation of arts engagement.Public Health and primary careGeriatrics in primary car

Identification of InuR, a new Zn(II)2Cys6 transcriptional activator involved in the regulation of inulinolytic genes in Aspergillus niger

The expression of inulinolytic genes in Aspergillus niger is co-regulated and induced by inulin and sucrose. We have identified a positive acting transcription factor InuR, which is required for the induced expression of inulinolytic genes. InuR is a member of the fungal specific class of transcription factors of the Zn(II)2Cys6 type. Involvement of InuR in inulin and sucrose metabolism was suspected because of the clustering of inuR gene with sucB, which encodes an intracellular invertase with transfructosylation activity and a putative sugar transporter encoding gene (An15g00310). Deletion of the inuR gene resulted in a strain displaying a severe reduction in growth on inulin and sucrose medium. Northern analysis revealed that expression of inulinolytic and sucrolytic genes, e.g., inuE, inuA, sucA, as well as the putative sugar transporter gene (An15g00310) is dependent on InuR. Genome-wide expression analysis revealed, three additional putative sugar transporters encoding genes (An15g04060, An15g03940 and An17g01710), which were strongly induced by sucrose in an InuR dependent way. In silico analysis of the promoter sequences of strongly InuR regulated genes suggests that InuR might bind as dimer to two CGG triplets, which are separated by eight nucleotides

Introduction Improving occupational performance is a key service of occupational therapists and client-centred approach to care is central to clinical practice. As such it is important to comprehensively evaluate the quality of psychometric properties reported across measures of occupational performance; in order to guide assessment and treatment planning. Objective To systematically review the literature on the psychometric properties of child-report measures of occupational performance for children ages 2-18 years. Methods A systematic search of the following six electronic databases was conducted: CINAHL; Psy-cINFO; EMBASE; PubMed; the Health and Psychosocial Instruments (HAPI) database; and Google Scholar. The quality of the studies was evaluated against the COSMIN taxonomy of measurement properties and the overall quality of psychometric properties was evaluated using pre-set psychometric criteria. Results Fifteen articles and one manual were reviewed to assess the psychometric properties of the six measures-the PEGS, MMD, CAPE, PAC, COSA, and OSA- which met the inclusion criteria. Most of the measures had conducted good quality studies to evaluate the psychometric properties of measures (PEGS, CAPE, PAC, OSA); however, the quality of the studies for two of these measures was relatively weak (MMD, COSA). When integrating the quality of the psychometric properties of the measures with the quality of the studies, the PAC stood out as having superior psychometric qualities. Conclusions The overall quality of the psychometric properties of most measures was limited. There is a need for continuing research into the psychometric properties of child-report measures of occupational performance, and to revise and improve the psychometric properties of existing measures

The Transcriptional Repressor TupA in Aspergillus niger Is Involved in Controlling Gene Expression Related to Cell Wall Biosynthesis, Development, and Nitrogen Source Availability.

The Tup1-Cyc8 (Ssn6) complex is a well characterized and conserved general transcriptional repressor complex in eukaryotic cells. Here, we report the identification of the Tup1 (TupA) homolog in the filamentous fungus Aspergillus niger in a genetic screen for mutants with a constitutive expression of the agsA gene. The agsA gene encodes a putative alpha-glucan synthase, which is induced in response to cell wall stress in A. niger. Apart from the constitutive expression of agsA, the selected mutant was also found to produce an unknown pigment at high temperatures. Complementation analysis with a genomic library showed that the tupA gene could complement the phenotypes of the mutant. Screening of a collection of 240 mutants with constitutive expression of agsA identified sixteen additional pigment-secreting mutants, which were all mutated in the tupA gene. The phenotypes of the tupA mutants were very similar to the phenotypes of a tupA deletion strain. Further analysis of the tupA-17 mutant and the DeltatupA mutant revealed that TupA is also required for normal growth and morphogenesis. The production of the pigment at 37 degrees C is nitrogen source-dependent and repressed by ammonium. Genome-wide expression analysis of the tupA mutant during exponential growth revealed derepression of a large group of diverse genes, including genes related to development and cell wall biosynthesis, and also protease-encoding genes that are normally repressed by ammonium. Comparison of the transcriptome of up-regulated genes in the tupA mutant showed limited overlap with the transcriptome of caspofungin-induced cell wall stress-related genes, suggesting that TupA is not a general suppressor of cell wall stress-induced genes. We propose that TupA is an important repressor of genes related to development and nitrogen metabolism

Assessment of motor functioning in the preschool period

The assessment of motor functioning in young children has become increasingly important in recent years with the acknowledgement that motor impairment is linked with cognitive, language, social and emotional difficulties. However, there is no one gold standard assessment tool to investigate motor ability in children. The aim of the current paper was to discuss the issues related to the assessment of motor ability in young pre-school children and to provide guidelines on the best approach for motor assessment. The paper discusses the maturational changes in brain development at the preschool level in relation to motor ability. Other issues include sex differences in motor ability at this young age, and evidence for this in relation to sociological versus biological influences. From the previous literature it is unclear what needs to be assessed in relation to motor functioning. Should the focus be underlying motor processes or movement skill assessment? Several key assessment tools are discussed that produce a general measure of motor performance followed by a description of tools that assess specific skills, such as fine and gross motor, ball and graphomotor skills. The paper concludes with recommendations on the best approach in assessing motor function in pre-school children

The construct validity of the Dutch version of the activity card sort

PURPOSE: Establishing construct validity of the ACS-NL in individuals with Parkinson's disease (PD). METHOD: Discriminative validity was established in 191 community-dwelling individuals with PD using an extreme groups design (Hoehn and Yahr stages 1 and 3). Convergent validity was determined by relating the performance scores of the ACS-NL to the scores of the Canadian Occupational Performance Measure (COPM) and the Parkinson's Disease Questionnaire (PDQ-39) scores, and relating ACS-NL satisfaction scores to the COPM scores and to the Utrecht Scale for Evaluation of Rehabilitation Participation (USER-P). RESULTS: The ACS-NL discriminated between individuals with PD with H&Y stages 1 and 3 (U = 524.5, Z = -5.453). ACS-NL performance scores correlated weakly with COPM scores (r = (0).19) and moderately with PDQ-39 scores (r = 0.44-0.55). The ACS-NL satisfaction scores correlated weakly with COPM scores (r = 0.23), and moderately with USER-P scores (r ≥ 0.40). CONCLUSIONS: This study contributed to the validation of the ACS-NL. The assessment enhances the possibility of monitoring participation in activities in individuals with PD. Implications for Rehabilitation The ACS-NL appears to hold good potential for use in the assessment of participation in activities in individuals with PD. The ACS-NL has added value parallel to administration of other instruments measuring participation (COPM) and quality of life (PDQ-39). This study demonstrates the capacity of the ACS to measure a unique construct of participation and helps to improve the psychometric properties and administration of the ACS-NL in practice

Writing Readiness Inventory Tool in Context (WRITIC): Reliability and convergent validity

BACKGROUND/AIM: This study examined the reliability and convergent validity of the Writing Readiness Inventory Tool in Context, a measurement evaluating writing readiness in kindergarten children (aged from five to six years). METHODS: Test-retest reliability was established with 59 children, inter-rater reliability with 72 children and convergent validity with 119 children. All participants were typically developing kindergarten children. Convergent validity was examined with the Beery-Buktenica Developmental Test of Visual-Motor Integration and the Nine-Hole Peg Test. RESULTS: We found excellent test-retest and inter-rater reliability on the future norm-referenced subdomain 'Task performance' of Writing Readiness Inventory Tool in Context with intra-class correlation coefficient ranging from 0.92 to 0.95. On the other criterion-referenced subdomains, we found fair to good reliability with intra-class correlation coefficient ranging from 0.70 to 1.0 and weighted Kappa ranging from 0.30 to 0.89. Correlations with the Beery-Buktenica Developmental Test of Visual-Motor Integration and the Nine-Hole Peg Test were moderate with rs ranging from 0.34 to 0.40 and these are comparable with correlations in other handwriting studies. CONCLUSION: Writing Readiness Inventory Tool in Context is an assessment of writing readiness that is stable over time and between raters. The expected moderate correlations with the Beery-Buktenica Developmental Test of Visual-Motor Integration and the Nine-Hole Peg Test support the construct of writing readiness
