Participation measures that evaluate attendance and involvement for young people aged 15 to 25 years with cerebral palsy: a systematic review.

PURPOSE: To identify participation-focused measures used for young people with cerebral palsy (CP), evaluate their psychometric evidence, and map item content to the International Classification of Functioning, Disability, and Health (ICF), and family of Participation-Related Constructs (fPRC) frameworks. METHODS: Four databases (PubMed, Embase, Web of Science, CINAHL) were searched for papers that involved young people with CP aged 15 to 25 years and reported original data from a participation measure. Each measure was examined for validity, reliability, responsiveness (using the COSMIN checklist), clinical utility, the inclusion of accessible design features, self- and/or proxy-report from people with communication support needs, and item content according to ICF and fPRC. RESULTS: Of 895 papers, 80 were included for review. From these, 26 measures were identified. Seven measures (27 papers/resources) were participation-focused, capable of producing a score for participation Attendance and/or Involvement. Of these, all measured Attendance (n = 7) but fewer than half measured Involvement (n = 3). Few included studies (37%) reported including some self-report of people with communication support needs. CONCLUSIONS: Participation measures for young people with CP are evolving but require more: (i) emphasis on measurement of involvement; (ii) investigation of psychometric properties; and (iii) adaptation to enable self-report by young people with communication support needs.IMPLICATIONS FOR REHABILITATIONIdentifies seven participation-focused measures which are available for young people with cerebral palsy, all seven measure Attendance and three measure Involvement.Provides a decision-making tool to assist clinicians and researchers with the selection of participation-focused measures for young people with cerebral palsy.Recommends that more accessible self-report measures are needed which capture age-appropriate participation of young people with cerebral palsy

Reflections on Participation at Home, As Self-Reported by Young People with Cerebral Palsy.

This study explored the home-based participation of young people with cerebral palsy (CP) and described factors that make participation easier or harder. Fifteen young people with CP aged 15 to 26 years provided written reflections, photographs, or videos about their home-based participation experiences. Data were analyzed using reflexive thematic analysis. Self-reported reflections were grouped inductively into 129 codes, then 20 subthemes and 5 themes which emphasized CP characteristics, thoughts, emotions, equipment, environment, supports, and inclusion as important factors influencing home-based participation. Young people with CP largely described the home environment as an inclusive place to participate

Factors impacting positive and negative participation of young people with cerebral palsy: a Delphi study of consumers and health professionals.

Purpose: To identify specific factors influencing the participation experiences of young people with cerebral palsy (CP) aged 15 to 26 years.Materials and methods: A three-round Delphi survey study design was used. Consumers (young people with CP and caregivers) and health professionals were asked to generate and then rate items influencing positive and negative participation experiences. Qualitative content analysis and descriptive statistics were used to classify items across the family of Participation-Related Constructs (fPRC) framework.Results: Sixty-eight participants completed Round I (25 consumers, 43 health professionals). Round II resulted in a consensus for all but two items, with Round III not required. The fPRC construct with the most items rated as extremely important for positive participation experiences was Environment-Availability, and for negative participation, experiences were Environment-Acceptability for both adolescents and young adults.Conclusions: A consensus was reached on the most important items influencing the positive and negative participation experiences of young people with CP. These items should be prioritised when developing support services and allocating funding to improve the participation experiences of young people with CP.Implications for RehabilitationThis study is reporting consumer and professional consensus on the factors promoting positive and negative participation for young people with cerebral palsy.Ensuring availability of appropriate activities and services is extremely important for enabling positive participation experiences.Promoting acceptable attitudes of others is extremely important for alleviating negative participation experiences

Eddy-Current Detection of Pitting Corrosion in Aircraft Lap-Splices

Corrosion is one of the most important limits on the life of transport aircraft. The outer skin of transports consists of thin sheets of aluminum that in many aircraft are fastened at lap-splices. The infiltration of moisture initiates corrosion between the sheets and thus internally erodes the outer covering of the plane. A substantial effort has been undertaken to find ways to detect and quantitatively measure such hidden corrosion. It has been shown that the swept-frequency or pulsed eddy-current impedance can be used to quantitatively measure uniform loss of material (over areas \u3e 1 cm2) in both the first and second layers of the lap-splice [1, 2, 3]. Consequently, eddy-currents form the basis for a quantitative inspection system. However, corrosion does not always result in a uniform loss of material. Sometimes the loss is highly localized and is aptly described as “pitting corrosion”. Consequently, there is a need for understanding the effects of such pits on the eddy-current response

Rapid adaptation to invasive predators overwhelms natural gradients of intraspecific variation

Invasive predators can exert strong selection on native populations. If selection is strong enough, populations could lose the phenotypic variation caused by adaptation to heterogeneous environments. We compare frog tadpoles prior to and 14 years following invasion by crayfish. Prior to the invasion, populations differed in their intrinsic developmental rate, with tadpoles from cold areas reaching metamorphosis sooner than those from warm areas. Following the invasion, tadpoles from invaded populations develop faster than those from non-invaded populations. This ontogenetic shift overwhelmed the intraspecific variation between populations in a few generations, to the point where invaded populations develop at a similar rate regardless of climate. Rapid development can have costs, as fast-developing froglets have a smaller body size and poorer jumping performance, but compensatory growth counteracts some costs of development acceleration. Strong selection by invasive species can disrupt local adaptations by dampening intraspecific phenotypic variation, with complex consequences on lifetime fitness

Structural Differences between the Streptococcus agalactiae Housekeeping and Pilus-Specific Sortases: SrtA and SrtC1

The assembly of pili on the cell wall of Gram-positive bacteria requires transpeptidase enzymes called sortases. In Streptococcus agalactiae, the PI-1 pilus island of strain 2603V/R encodes two pilus-specific sortases (SrtC1 and SrtC2) and three pilins (GBS80, GBS52 and GBS104). Although either pilus-specific sortase is sufficient for the polymerization of the major pilin, GBS80, incorporation of the minor pilins GBS52 and GBS104 into the pilus structure requires SrtC1 and SrtC2, respectively. The S. agalactiae housekeeping sortase, SrtA, whose gene is present at a different location and does not catalyze pilus polymerization, was shown to be involved in cell wall anchoring of pilus polymers. To understand the structural basis of sortases involved in such diverse functions, we determined the crystal structures of S. agalactiae SrtC1 and SrtA. Both enzymes are made of an eight-stranded beta-barrel core with variations in their active site architecture. SrtA exhibits a catalytic triad arrangement similar to that in Streptococcus pyogenes SrtA but different from that in Staphylococcus aureus SrtA. In contrast, the SrtC1 enzyme contains an N-terminal helical domain and a ‘lid’ in its putative active site, which is similar to that seen in Streptococcus pneumoniae pilus-specific sortases, although with subtle differences in positioning and composition. To understand the effect of such differences on substrate recognition, we have also determined the crystal structure of a SrtC1 mutant, in which the conserved DP(W/F/Y) motif was replaced with the sorting signal motif of GBS80, IPNTG. By comparing the structures of WT wild type SrtA and SrtC1 and the ‘lid’ mutant of SrtC1, we propose that structural elements within the active site and the lid may be important for defining the role of specific sortase in pili biogenesis

Change & Maintaining Change in School Cafeterias: Economic and Behavioral-Economic Approaches to Increasing Fruit and Vegetable Consumption

Developing a daily habit of consuming fruits and vegetables (FV) in children is an important public-health goal. Eating habits acquired in childhood are predictive of adolescent and adult dietary patterns. Thus, healthy eating patterns developed early in life can protect the individual against a number of costly health deficits and may reduce the prevalence of obesity. At present, children in the United States (US) under-consume FV despite having access to them through the National School Lunch Program. Because access is an obstacle to developing healthy eating habits, particularly in low-income households, targeting children’s FV consumption in schools has the advantage of near-universal FV availability among more than 30 million US children. This chapter reviews economic and behavioral-economic approaches to increasing FV consumption in schools. Inclusion criteria include objective measurement of FV consumption (e.g., plate waste measures) and minimal demand characteristics. Simple but effective interventions include (a) increasing the variety of vegetables served, (b) serving sliced instead of whole fruits, (c) scheduling lunch after recess, and (d) giving children at least 25 minutes to eat. Improving the taste of FV and short-term incentivizing consumption of gradually increasing amounts can produce large increases in consumption of these foods. Low-cost game-based incentive program may increase the practicality of the latter strategy
