Attachment of cells to islands presenting gradients of adhesion ligands

This paper reports a strategy that uses microfluidic networks to pattern self-assembled monolayers with gradient microislands for the attachment of individual cells. A microfluidic network is first used to pattern a monolayer into square regions that present maleimide groups and then used to flow a solution having a gradient of the cell adhesion peptide Arg-Gly-Asp over the substrate. In this way, the surface is patterned with microislands approximately 33 x 33 micrometers in size and each having a defined gradient of immobilized cell adhesion ligand. B16F10 cells were allowed to attach to the patterned islands and were found to display a nonuniform distribution of cytoskeletal structures in response to the gradient of adhesion ligand. This work is significant because it permits studies of the influence of a nonuniform microenvironment on the polarization, differentiation, and signaling of adherent cells

Quality of Life and Autonomy in Emerging Adults with Early‐Onset Neuromuscular Disorders

Emerging adulthood is an important period in the development of one’s identity and autonomy. The ways in which identity and autonomy are viewed by emerging adults and how they impact quality of life (QoL) in individuals with early‐onset neuromuscular conditions is not yet known. This study focused on understanding and exploring relationships between self‐perceptions of emerging adulthood, autonomy, and QoL. Five previously validated measures were incorporated into an online survey and distributed to young adults with early‐onset neuromuscular conditions and unaffected controls. Topics explored included individuals’ views regarding their overall QoL, disease‐specific QoL, components of emerging adulthood, and autonomy. We found that a sense of higher disease impact was associated with a lower Overall General QoL. Additionally, perceptions of key autonomy factors “negativity” and “instability” were uniquely associated with Overall General QoL in the case group as compared to controls, whereas “attitudinal autonomy” (attaining the ability to plan and follow through with goals) was important to this age group regardless of health status. The specific factors of emerging adulthood and autonomy that were significantly correlated with Overall General QoL can be used for developing targeted counseling and interventions to improve QoL for individuals and their families.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146967/1/jgc40713.pd

“At Least until the Second Wave Comes…”: A Twitter analysis of the NHS and COVID-19 between March and June 2020

In the UK, tweets around COVID-19 and health care have primarily focused on the NHS. Recent research has identified that the psychological well-being of NHS staff has been adversely impacted as a result of the COVID-19 pandemic. The aim of this study was to investigate narratives relating to the NHS and COVID-19 during the first lockdown (26 March–4 July 2020). A total of 123,880 tweets were collated and downloaded bound to the time period of the first lockdown in order to analyse the real-time discourse around COVID-19 and the NHS. Content analysis was undertaken and tweets were coded to positive and negative sentiments. Five main themes were identified: (1) the dichotomies of ‘clap for carers’; (2) problems with PPE and testing; (3) peaks of anger; (4) issues around hero worship; and (5) hints of a normality. Further research exploring and documenting social media narratives around COVID-19 and the NHS, in this and subsequent lockdowns, should help in tailoring suitable support for staff in the future and acknowledging the profound impact that the pandemic has had

A randomized trial to determine the impact on compliance of a psychophysical peripheral cue based on the Elaboration Likelihood Model

Objective: Non-compliance in clinical studies is a significant issue, but causes remain unclear. Utilizing the Elaboration Likelihood Model of persuasion, this study assessed the psychophysical peripheral cue ‘Interactive Voice Response System (IVRS) call frequency’ on compliance. Methods: 71 participants were randomized to once daily (OD), twice daily (BID) or three times daily (TID) call schedules over two weeks. Participants completed 30-item cognitive function tests at each call. Compliance was defined as proportion of expected calls within a narrow window (± 30 min around scheduled time), and within a relaxed window (− 30 min to + 4 h). Data were analyzed by ANOVA and pairwise comparisons adjusted by the Bonferroni correction. Results: There was a relationship between call frequency and compliance. Bonferroni adjusted pairwise comparisons showed significantly higher compliance (p = 0.03) for the BID (51.0%) than TID (30.3%) for the narrow window; for the extended window, compliance was higher (p = 0.04) with OD (59.5%), than TID (38.4%). Conclusion: The IVRS psychophysical peripheral cue call frequency supported the ELM as a route to persuasion. The results also support OD strategy for optimal compliance. Models suggest specific indicators to enhance compliance with medication dosing and electronic patient diaries to improve health outcomes and data integrity respectively

The cigarette box as an advertising vehicle in the UK : a case for plain packaging

This research aimed to study tobacco advertising between 1950-2003 and to evaluate the role of the cigarette box in advertising. Tobacco company advertisements (n = 204) were coded for content and meanings used to promote their product. There was a significant shift from cigarettes being displayed to the cigarette box only. Changes in advertising and the meanings evoked were unrelated to changes in smoking behaviour. It is argued that the cigarette box has absorbed the meanings associated with smoking and has become an effective vehicle for advertising. It is also argued that this can only be minimised with plain packaging

Qualitative investigation of exercise perceptions and experiences in people with multiple sclerosis before, during, and after participation in a personally tailored exercise program

Objective To undertake a qualitative investigation of exercise perceptions and experiences in people with multiple sclerosis (PwMS) before, during, and after participation in a personally tail ored program designed to promote long-term maintenance of self-directed exercise. Design Focus groups and semistructured telephone interviews. Setting University exercise science department close to the recruiting hospital. Participants PwMS (N=33; mean age ± SD, 47.6±7.9y). Interventions Participants were recruited after participation in a randomized controlled exercise trial; all had been allocated to a 12-week exercise program comprising supervised and self-directed exercise sessions. Main Outcome Measures Exercise perceptions and experiences before, during, and after participation in the program. Results Four themes emerged from the analysis: (1) the transition to inactivity; (2) lack of knowledge and confidence; (3) positive exercise experiences; and (4) perspectives on exercise adherence. Conclusions Lack of confidence and exercise knowledge, coupled with negative perceptions about physical capabilities after an MS diagnosis, are clear barriers to exercise participation in PwMS. These issues are not being adequately addressed as part of the health care pathway or in community settings. Perceptions of improved posture, ability to overcome everyday difficulties, acute mood enhancements during and after exercise, and increased opportunities for social interaction were among the reported benefits of exercise participation. Despite the provision of a personally tailored exercise plan and use of cognitive behavioral strategies, self-directed exercise continued to present challenges to PwMS, and the importance of seeking cost-effective ways to maintain motivational support was implicit in participant responses

Mental Health and Well-Being in Mothers of Children With Rare Genetic Syndromes Showing Chronic Challenging Behavior::A Cross-Sectional and Longitudinal Study

It is well documented that mothers of children with challenging behavior (CB) experience elevated levels of stress and that this persists over time, but less is known about the experience of mothers of children with rare genetic syndromes. This article describes 2 studies, 1 cross-sectional and 1 longitudinal, comparing well-being in mothers of children with Angelman, Cornelia de Lange and Cri du Chat syndrome who have either shown chronic CB (n = 18) or low/no CB (n = 26) in the preceding 7 years. The presence of chronic, long-term CB increased maternal stress but not depression or anxiety, and did not influence positive well-being. Stress relating specifically to their child's genetic syndrome reduced with age, highlighting the need for further exploration in this area.Arts, Education & Law Group, School of Education and Professional StudiesFull Tex

Participant recruitment into a randomised controlled trial of exercise therapy for people with multiple sclerosis

The success of a clinical trial is often dependant on whether recruitment targets can be met in the required time frame. Despite an increase in research into the benefits of exercise in people with multiple sclerosis (PwMS), no trial has reported detailed data on effective recruitment strategies for large-scale randomised controlled trials. The main purpose of this report is to provide a detailed outline of recruitment strategies, rates and estimated costs in the Exercise Intervention for Multiple Sclerosis (ExIMS) trial to identify best practices for future trials involving multiple sclerosis (MS) patient recruitment

Effect of the Growth Assessment Protocol on the DEtection of Small for GestatioNal age fetus: process evaluation from the DESiGN cluster randomised trial

BACKGROUND: Reducing the rate of stillbirth is an international priority. At least half of babies stillborn in high-income countries are small for gestational-age (SGA). The Growth Assessment Protocol (GAP), a complex antenatal intervention that aims to increase the rate of antenatal detection of SGA, was evaluated in the DESiGN type 2 hybrid effectiveness-implementation cluster randomised trial (n = 13 clusters). In this paper, we present the trial process evaluation. METHODS: A mixed-methods process evaluation was conducted. Clinical leads and frontline healthcare professionals were interviewed to inform understanding of context (implementing and standard care sites) and GAP implementation (implementing sites). Thematic analysis of interview text used the context and implementation of complex interventions framework to understand acceptability, feasibility, and the impact of context. A review of implementing cluster clinical guidelines, training and maternity records was conducted to assess fidelity, dose and reach. RESULTS: Interviews were conducted with 28 clinical leads and 27 frontline healthcare professionals across 11 sites. Staff at implementing sites generally found GAP to be acceptable but raised issues of feasibility, caused by conflicting demands on resource, and variable beliefs among clinical leaders regarding the intervention value. GAP was implemented with variable fidelity (concordance of local guidelines to GAP was high at two sites, moderate at two and low at one site), all sites achieved the target to train > 75% staff using face-to-face methods, but only one site trained > 75% staff using e-learning methods; a median of 84% (range 78–87%) of women were correctly risk stratified at the five implementing sites. Most sites achieved high scores for reach (median 94%, range 62–98% of women had a customised growth chart), but generally, low scores for dose (median 31%, range 8–53% of low-risk women and median 5%, range 0–17% of high-risk women) were monitored for SGA as recommended. CONCLUSIONS: Implementation of GAP was generally acceptable to staff but with issues of feasibility that are likely to have contributed to variation in implementation strength. Leadership and resourcing are fundamental to effective implementation of clinical service changes, even when such changes are well aligned to policy mandated service-change priorities.
