Effectiveness of the interventions in preventing the progression of pre-frailty and frailty in older adults:a systematic review protocol

REVIEW QUESTION / OBJECTIVE : The objective of this review is to identify the effectiveness of the interventions in preventing progression of pre-frailty and frailty in older adults. More specifically, the review questions are: - What is the effectiveness of interventions in preventing or reducing frailty in older adults? - How does effectiveness vary with degree of frailty? - Are there factors that influence the effectiveness of interventions? - What is the economic feasibility of interventions for pre-frailty and frailty? INCLUSION CRITERIA : Types of participants This review will consider studies that include older adults (female and male) aged 65 years and over, explicitly identified as pre-frail or frail by the researchers or associated medical professionals according to a pre-specified scale or index, and who have received health care and support services in any type of setting (primary care, nursing homes, hospitals). This review will exclude studies that: - Include participants who have been selected because they have one specific illness - Consider people with a terminal diagnosis only. - Types of intervention(s)/phenomena of interest: The clinical/medical component of the review will consider studies that evaluate any type of interventions to prevent the progression of pre-frailty and frailty in older adults. These interventions will include, but will not be limited to, physical activity, multifactorial intervention, psychosocial intervention, health and social care provision, and cognitive, nutrition or medication/medical maintenance and adherence focused interventions. The economic component of the review will consider studies that have performed any type of health economic analysis of ...

Towards flexible parsing of structured textual model representations

Existing parsers for textual model representation formats such as XMI and HUTN are unforgiving and fail upon even the smallest inconsistency between the structure and naming of metamodel elements and the contents of serialised models. In this paper, we demonstrate how a fuzzy parsing approach can transparently and automatically resolve a number of these inconsistencies, and how it can eventually turn XML into a human-readable and editable textual model representation format for particular classes of models.

Long-term efficacy of orthokeratology contact lens wear in controlling the progression of childhood myopia

Purpose: The primary outcome of this study is to compare the axial length growth of white European myopic children wearing orthokeratology contact lenses (OK) to a control group (CT) over a 7-year period. Methods: Subjects 6–12 years of age with myopia −0.75 to −4.00DS and astigmatism ≤1.00DC were prospectively allocated OK or distance single-vision spectacles (SV) correction. Measurements of axial length (Zeiss IOLMaster), corneal topography, and cycloplegic refraction were taken at 6-month intervals over a 2-year period. Subjects were invited to return to the clinic approximately 5 years later (i.e., 7 years after the beginning of the study) for assessment of their ocular refractive and biometric components. The CT consisted of 4 SV and 12 subjects who switched from SV to soft contact lens wear after the initial 2 years of SV lens wear. Changes in axial length relative to baseline over a 7-year period were compared between groups. Results: Fourteen and 16 subjects from the OK and CT groups, respectively, were examined 6.7 ± 0.5 years after the beginning of the study. Statistically significant changes in the axial length were found over time and between groups (both p <0.001), but not for the time*group interaction (p = 0.125). The change in the axial length for the OK group was 22% (p = 0.328), 42% (p = 0.007), 40% (p = 0.020), 41% (p = 0.013), and 33% (p = 0.062) lower than the CT group following 6, 12, 18, 24, and 84 months of lens wear, respectively. Conclusion: A trend toward a reduction in the rate of axial elongation of the order of 33% was found in the OK group in comparison to the CT group following 7 years of lens wear.
