The development of a consensus statement for the prescription of powered wheelchair standing devices in Duchenne muscular dystrophy.

PURPOSE: To develop a consensus statement for the prescription of a Powered Wheelchair Standing Device (PWSD) in young people with Duchenne muscular dystrophy (DMD). MATERIALS AND METHODS: An international multidisciplinary panel comprising clinicians and users (young people with DMD) along with their parents was consulted. A literature review was undertaken and a Delphi method was utilised to generate consensus statements. To supplement limited literature, round one of the Delphi process comprised questions consistent with the International Classification of Functioning, Disability and Health model of disability to generate items based on expert opinion and was completed by 38 clinicians and nine users. Thirty-seven participants completed two further rounds rating the importance of each item with a five-point scale. Agreement of 70% or more participants for items indicated consensus. RESULTS: Consensus was reached for 47 of 80 items. Tolerance and comfort in supported standing for at least 10 min, ankle contracture less than 10 degrees and user goals reflecting motivation to use the standing function were agreed as necessary in guiding the decision to trial a PWSD. Evidence of family, therapist and servicing support were also considered critical in enabling continuity of PWSD use. CONCLUSIONS: PWSD is a mobility option that offers choice, control and opportunity for independence. This consensus statement can assist clinicians with decision-making around factors influencing successful implementation and optimisation of PWSD for young people with DMD.Implications for RehabilitationTolerance and comfort in supported standing for at least 10 minutes, ankle contracture limited to less than 10 degrees and the child's goals reflecting motivation to use the standing position were agreed to be necessary considerations in guiding the decision to trial a PWSD.Trialling a PWSD when the child is predicted to lose the ability to walk within a one to two year period was recommended although a PWSD could be suitable for a child who was unable to walk.Evidence of family, therapist and servicing support was considered critical in enabling continuity of PWSD use.

Red palm oil as a source of beta-carotene in a school biscuit used to address vitamin A deficiency in primary school children.

The effect of a biscuit with red palm oil as a source of beta-carotene was compared with the effect of a biscuit with beta-carotene from a synthetic source on the vitamin A status of primary school children in a randomised controlled trial. Children aged 5-11 years (n = 265) were randomly assigned to one of three groups: (1) placebo biscuit; (2) biscuit with synthetic beta-carotene as a vitamin A fortificant; and (3) biscuit with red palm oil as a source of beta-carotene. The two non-placebo biscuits were designed to provide 34% of the RDA for vitamin A per serving (4 x 15 g biscuits). The biscuits were distributed daily during the school week and compliance was closely monitored and recorded. Children were assessed at baseline and after 6 months of intervention. Mean serum retinol in all three groups increased significantly compared to baseline (P < 0.0001). The prevalence of low serum retinol levels (< 20 micrograms/dL) dropped from 50 to 24.4% in the control group, from 48.2 to 16.9% in the synthetic beta-carotene group, and from 50.6 to 22.8% in the red palm oil group. There was no significant treatment effect compared to the control group in either the synthetic beta-carotene or red palm oil group. The increase in the control group was probably due to a school feeding scheme (providing 33% of the RDA for vitamin A) introduced during the latter part of the study. Our results were thus confounded and the 'true' effect of the red palm oil biscuit on vitamin A status could not be established. The study has, however, shown that red palm oil can be incorporated in a biscuit and that the end product with regard to taste and appearance was well accepted by the school children. A follow-up study in a school where there is no school feeding is indicated.
