    Abstract DNA is naturally dynamic and can self-assemble into alternative secondary structures including the intercalated motif (i-motif), a four-stranded structure formed in cytosine-rich DNA sequences. Until recently, i-motifs were thought to be unstable in physiological cellular environments. Studies demonstrating their existence in the human genome and role in gene regulation are now shining light on their biological relevance. Herein, we review the effects of epigenetic modifications on i-motif structure and stability, and biological factors that affect i-motif formation within cells. Furthermore, we highlight recent progress in targeting i-motifs with structure-specific ligands for biotechnology and therapeutic purposes.

    Abstract Understanding the day-to-day lived experiences of individuals who have had or are still recovering from Coronavirus Disease-19 (COVID-19), whilst a complex challenge, presents the opportunity to listen and learn. Composite vignettes provide a novel approach to explore and present descriptive portrayals of the most commonly derived experiences and recovery journeys. The thematic analysis of 47 shared accounts (semi-structured interviews with adults aged ≥18 years; 40 females; 6-11 months post-COVID-19 infection) produced a series of four intricate character stories written through the lens of a single individual. Each vignette gives a voice to and captures a different experience trajectory. From the point of initial symptom development onwards, the vignettes depict how COVID-19 has affected everyday lives, focusing on the secondary non-biological socio-psychological effects and implications. The vignettes highlight in participants' own words: i) the potential negative implications of not addressing the psychological effects of COVID-19; ii) the lack of symptom and recovery linearity; iii) the ongoing 'lottery' of access to healthcare services; and iv) the highly variable, yet generally devastating, impacts that COVID-19 and consequent long-COVID has had across multiple facets of daily living.

    Abstract The conceptualisation and visualisation of physical activity through 3D-printed objects offers a unique means by which to elicit positive behaviour change. This study aimed to explore whether 3D-printed models of physical activity obtain autotopographical meaning in youths and the influence of such models on their sense of personal and social identity. Following participation in a seven-week faded intervention, whereby habitual physical activity was measured and used to create individual 3D models, the views of 61 participants (36 boys; 10.9 ± 3.0 years) were explored via semi-structured focus groups. Within the over-arching theme of '3D-Printed Models', key emergent sub-themes were structured around 'Autotopography', 'Reflection', 'In-group norms', and 'Significant others'. Investing meaning in the material representations facilitated social activation and self-reflection on their own behaviour, both of which are key elements of identity formation. The influential role of significant others (familial and peers) within initial model interpretation and their potential long-term efficacy as a behaviour change approach was highlighted. 3D-printed models present a novel concept and intervention approach and may represent a useful component within behaviour change engagement strategies in children and adolescents.

    Abstract Importance: Assessment of tactile perception is foundational for addressing aspects of occupational performance.
    Objective: To evaluate the construct validity and internal reliability of four new tactile perception tests.
    Design: Causal comparative groups design.
    Settings: Homes, schools, and therapy practices across the United States.
    Participants: Children ages 3 to 12 yr: typically developing (n = 174) and those with sensory integration concerns (n = 153).
    Outcomes and measures: Rasch analyses to evaluate construct validity; analysis of covariance to evaluate group differences.
    Results: The Rasch model confirmed evidence of construct validity for each of the four tests. The typically developing group scored significantly higher than the clinical group on all tests (η2p = .040-.105, p < .001). Person reliability indices and strata indicated moderate to strong internal reliability (Rasch person reliability indices = .69-.87; strata = 2.33-3.82).
    Conclusions and relevance: The Evaluation in Ayres Sensory Integration® (EASI) Tactile Perception Tests are reliable and valid measures for assessing tactile perception in children ages 3 to 12 yr. Findings suggest that these tests are likely to be clinically useful and appropriate for children in this age range and may provide critical information regarding underlying sensory functions necessary for optimal occupational performance. What This Article Adds: This article provides data supporting the reliability and validity of the EASI Tactile Perception Tests in a U.S.
    Sample: These assessments can be used by therapists trained in their administration to assess tactile functions that may affect participation in activities, tasks, and occupations.

    Abstract Context: Nutrition care is an effective lifestyle intervention for the treatment and prevention of many noncommunicable diseases. Primary care is a high-value setting in which to provide nutrition care.
    Objective: The objective of this review was to evaluate the cost-effectiveness of nutrition care interventions provided in primary care settings.
    Data sources: Medline, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Cochrane Central Register of Controlled Trials, EconLit, and the National Health Service Economic Evaluation Database (NHS EED) were searched from inception to May 2021.
    Data extraction: Data extraction was guided by the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) reporting guidelines. Randomized trials of nutrition interventions in primary care settings were included in the analysis if incremental cost-effectiveness ratios were reported. The main outcome variable incremental cost-effectiveness ratios (ICERs) and reported interpretations were used to categorize interventions by the cost-effectiveness plane quadrant.
    Results: Of 6837 articles identified, 10 were included (representing 9 studies). Eight of the 9 included studies found nutrition care in primary care settings to be more costly and more effective than usual care. High study heterogeneity limited further conclusions.
    Conclusion: Nutrition care in primary care settings is effective, though it requires investment; it should, therefore, be considered in primary care planning. Further studies are needed to evaluate the long-term cost-effectiveness of providing nutrition care in primary care settings.
