AIM To examine which instruments used to assess participation of children with acquired brain injury (ABI) or cerebral palsy (CP) align with attendance and/or involvement constructs of participation; and to systematically review measurement properties of these instruments in children with ABI or CP, to guide instrument selection. METHOD Five databases were searched. Instruments that quantified ‘attendance’ and/or ‘involvement’ aspects of participation according to the family of participation-related constructs were selected. Data on measurement properties were extracted and methodological quality of the studies assessed. RESULTS Thirty-seven instruments were used to assess participation in children with ABI or CP. Of those, 12 measured attendance and/or involvement. The reliability, validity, and responsiveness of eight of these instruments were examined in 14 studies with children with ABI or CP. Sufficient measurement properties were reported for most of the measures, but no instrument had been assessed on all relevant properties. Moreover, most psychometric studies have marked methodological limitations. INTERPRETATION Instruments to assess participation of children with ABI or CP should be selected carefully, as many available measures do not align with attendance and/or involvement. Evidence for measurement properties is limited, mainly caused by low methodological study quality. Future studies should follow recommended methodological guidelines.
BACKGROUND: The Quebec Back Pain Disability Scale (QBPDS) has been translated into different languages, and several studies on its measurement properties have been done. PURPOSE: The purpose of this review was to critically appraise and compare the measurement properties, when possible, of all language versions of the QBPDS by systematically reviewing the methodological quality and results of the available studies. METHOD: Bibliographic databases (PubMed, Embase, CINAHL, and PsycINFO) were searched for articles with the key words "Quebec," "back," "pain," and "disability" in combination with a methodological search filter for finding studies on measurement properties concerning the development or evaluation of the measurement properties of the QBPDS in patients with nonspecific low back pain. Assessment of the methodological quality was carried out by the reviewers using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist for both the original language version of the QBPDS in English and French and all translated versions. The results of the measurement properties were rated based on criteria proposed by Terwee et al. RESULTS: The search strategy resulted in identification of 1,436 publications, and 27 articles were included in the systematic review. There was limited-to-moderate evidence of good reliability, validity, and responsiveness of the QBPDS for the different language versions, but for no language version was evidence available for all measurement properties. CONCLUSION: For research and clinical practice, caution is advised when using the QBPDS to measure disability in patients with nonspecific low back pain. Strong evidence is lacking on all measurement properties for each language version of the QBPDS.
BACKGROUND: Regular inspection of the oral cavity is required for prevention, early diagnosis and risk reduction of oral- and general health-related problems. Assessments to inspect the oral cavity have been designed for non-dental healthcare professionals, like nurses. The purpose of this systematic review was to evaluate the content and the measurement properties of oral health assessments for use by non-dental healthcare professionals in assessing older peoples' oral health, in order to provide recommendations for practice, policy, and research.METHODS: A systematic search in PubMed, EMBASE.com, and Cinahl (via Ebsco) has been performed. Search terms referring to 'oral health assessments', 'non-dental healthcare professionals' and 'older people (60+)' were used. Two reviewers individually performed title/abstract, and full-text screening for eligibility. The included studies have investigated at least one measurement property (validity/reliability) and were evaluated on their methodological quality using "The Consensus-based Standards for the selection of health Measurement Instruments" (COSMIN) checklist. The measurement properties were then scored using quality criteria (positive/negative/indeterminate).RESULTS: Out of 879 hits, 18 studies were included in this review. Five studies showed good methodological quality on at least one measurement property and 14 studies showed poor methodological quality on some of their measurement properties. None of the studies assessed all measurement properties of the COSMIN. In total eight oral health assessments were found: the Revised Oral Assessment Guide (ROAG); the Minimum Data Set (MDS), with oral health component; the Oral Health Assessment Tool (OHAT); The Holistic Reliable Oral Assessment Tool (THROAT); Dental Hygiene Registration (DHR); Mucosal Plaque Score (MPS); The Brief Oral Health Screening Examination (BOHSE) and the Oral Assessment Sheet (OAS). Most frequently assessed items were: lips, mucosa membrane, tongue, gums, teeth, denture, saliva, and oral hygiene.CONCLUSION: Taken into account the scarce evidence of the proposed assessments, the OHAT and ROAG are most complete in their included oral health items and are of best methodological quality in combination with positive quality criteria on their measurement properties. Non-dental healthcare professionals, policymakers and researchers should be aware of the methodological limitations of the available oral health assessments and realize that the quality of the measurement properties remains uncertain.
The ENCHANT project aims to clarify the differences between circular Calcium Carbonate (CCC) and grounded Calcium Carbonate (GCC), in order to expand the applications of the circular alternative CCC in the paint and coating industry. CCC is produced by pyrolysis from paper waste in an innovative process developed by the company Alucha Works B.V., and it can be applied again as filler or binder in consumer products (e.g. plastics, rubbers, paints and coatings) in a cost-effective manner. Products containing CCC have a higher content of circular resources, which minimizes their carbon footprint, and reduces the exploitation of primary resources. Performances of CCC in oil-based paints, however, is not optimal, due to a larger oil adsorption as compared to GCC. A physical and chemical characterization of CCC and GCC samples, including competitive oil-water adsorption measurements, would help Alucha to formulate a solution to match the properties of CCC and GCC, either adjusting the recycling process or applying a surface modification treatment to CCC. This would enable Alucha to expand the market for CCC, making oil-based formulation products more circular.
Human kind has a major impact on the state of life on Earth, mainly caused by habitat destruction, fragmentation and pollution related to agricultural land use and industrialization. Biodiversity is dominated by insects (~50%). Insects are vital for ecosystems through ecosystem engineering and controlling properties, such as soil formation and nutrient cycling, pollination, and in food webs as prey or controlling predator or parasite. Reducing insect diversity reduces resilience of ecosystems and increases risks of non-performance in soil fertility, pollination and pest suppression. Insects are under threat. Worldwide 41 % of insect species are in decline, 33% species threatened with extinction, and a co-occurring insect biomass loss of 2.5% per year. In Germany, insect biomass in natural areas surrounded by agriculture was reduced by 76% in 27 years. Nature inclusive agriculture and agri-environmental schemes aim to mitigate these kinds of effects. Protection measures need success indicators. Insects are excellent for biodiversity assessments, even with small landscape adaptations. Measuring insect biodiversity however is not easy. We aim to use new automated recognition techniques by machine learning with neural networks, to produce algorithms for fast and insightful insect diversity indexes. Biodiversity can be measured by indicative species (groups). We use three groups: 1) Carabid beetles (are top predators); 2) Moths (relation with host plants); 3) Flying insects (multiple functions in ecosystems, e.g. parasitism). The project wants to design user-friendly farmer/citizen science biodiversity measurements with machine learning, and use these in comparative research in 3 real life cases as proof of concept: 1) effects of agriculture on insects in hedgerows, 2) effects of different commercial crop production systems on insects, 3) effects of flower richness in crops and grassland on insects, all measured with natural reference situations
The application of sensors in water technology is a crucial step to provide broader, more efficient and circular systems. Among the different technologies used in this field, ultrasound-based systems are widely used, basically to generate energy peaks for cell lysis and particle separation. In this work, we propose the adaptation of an ultrasound system to monitor the concentration of solid particles in wastewater treatment plants settlers as well as to indicate sludge level (real time). A similar sensor was developed and tested in another project which operated successfully at solids concentration up to 1% in UASB reactors. Such measurements are nowadays obtained via time-consuming physical (solids) analysis, which can compromise the efficiency of the settlers and the quality of the effluent. The present project proposes an improved version of the sensor, which will combine solids concentration monitoring and sludge level detection. The defined targets have the intention to make a sensor with a much broader range of applications, been suitable not only for UASB reactors but also to settler and aerobic tanks. The project is a cooperation between the Water Technology lectoraat of NHL Stenden University of Applied Sciences, two SME’s - YNOVIO B.V. and Lamp-ion B.V. - and the INCT group (Brazil). If proven feasible, the concept can generate a big business market to the involved Dutch partners as well as favor the automation of WWTP in the Netherlands, Brazil and around the world.
