The ability of the Ages and Stages Questionnaire (ASQ) to indicate motor difficulties in infants in primary care

Introduction Delayed achievement of motor milestones may be an early indicator of motor difficulties. Parent-reported questionnaires may serve as an efficient, low-cost screening to identify infants in need of further clinical assessment, and thus be a helpful tool in busy health care centers. Purpose To examine the ability of the Ages and Stages Questionnaire, second edition (ASQ-2) to indicate motor difficulties in infants using the Infant Motor Profile (IMP) as the reference standard. Methods A cross-sectional design was applied to examine the correlation between parent-reported data of the ASQ-2 and data from physiotherapist assessment using IMP. Included were 432 mainly low-risk infants aged 3–12 months from primary care. Results Overall, ASQ-2 gross and fine motor scores did not correlate well with the IMP total or domain scores. The ASQ-2 gross motor cut point (> 2SD below the mean), showed 34.3% sensitivity and 96.7% specificity using the 15th percentile from IMP performance domain as reference standard. The positive predictive value to indicate motor difficulties was 48%. Conclusion The motor domains of ASQ-2 have poor ability to identify infants with motor difficulties as indicated by their IMP scores in low-risk infants.publishedVersio

The Early Sociocognitive Battery: a clinical tool for early identification of children at risk for social communication difficulties and ASD?

BACKGROUND: A substantial proportion of preschool children referred to speech and language therapy (SLT) services have social communication difficulties and/or autistic spectrum disorders (SC&/ASD) that are not identified until late childhood. These 'late' diagnosed children miss opportunities to benefit from earlier targeted interventions. Prior evidence from a follow-up clinical sample showed that preschool performance on the Early Sociocognitive Battery (ESB) was a good predictor of children with social communication difficulties 7-8 years later. AIMS: The aims were three-fold: (1) to determine the impact of child/demographic factors on ESB performance in a community sample of young children; (2) to assess the ESB's concurrent validity and test-retest reliability; and (3) to use cut-offs for 'low' ESB performance derived from the community sample data to evaluate in a clinical sample the predictiveness of the ESB at 2-4 years for outcomes at 9-11 years, including parent-reported SC&/ASD diagnosis. METHODS & PROCEDURES: A community sample of 205 children aged 2-4 years was assessed on the ESB and a receptive vocabulary test. A subsample (n = 20) was retested on the ESB within 2 weeks. Parents completed a questionnaire providing background child/demographic information. The clinical sample from our previous study comprised 93 children assessed on the ESB at 2;6 to < 4;0 whose parents completed the Social Responsiveness Scale (SRS), our measure of social communication, when the children were 9-11 years. Cut-offs for 'low' ESB performance derived from the community sample were used to determine the predictive validity of 'low' ESB scores for social communication outcomes and parent-reported SC&/ASD diagnosis according to age of ESB assessment. OUTCOME & RESULTS: Findings from the community sample confirmed the ESB as psychometrically robust, sensitive to age and language delay, and, in contrast to the receptive vocabulary measure, unaffected by bilingualism. While overall associations between ESB performance and later social communication difficulties in the clinical sample were particularly strong for the youngest age group (2;6 to < 3;0; r = .71, p < .001), 'low' ESB performance was equally predictive across age groups and overall identified 89% of children with 'late' SC&/ASD diagnoses (sensitivity), and 75% of those without (specificity). CONCLUSIONS & IMPLICATIONS: Results indicate that the ESB is a valid preschool assessment suitable for use with children from diverse language backgrounds. It identifies deficits in key sociocognitive skills and is predictive of social communication difficulties in school-age children that had not been identified in preschool clinical assessment, supporting earlier targeted interventions for these children

Extensive spontaneous plasticity of corticospinal projections after primate spinal cord injury.

Although axonal regeneration after CNS injury is limited, partial injury is frequently accompanied by extensive functional recovery. To investigate mechanisms underlying spontaneous recovery after incomplete spinal cord injury, we administered C7 spinal cord hemisections to adult rhesus monkeys and analyzed behavioral, electrophysiological and anatomical adaptations. We found marked spontaneous plasticity of corticospinal projections, with reconstitution of fully 60% of pre-lesion axon density arising from sprouting of spinal cord midline-crossing axons. This extensive anatomical recovery was associated with improvement in coordinated muscle recruitment, hand function and locomotion. These findings identify what may be the most extensive natural recovery of mammalian axonal projections after nervous system injury observed to date, highlighting an important role for primate models in translational disease research

Zinc for the treatment of diarrhoea: effect on diarrhoea morbidity, mortality and incidence of future episodes

Background Zinc supplementation for the treatment of diarrhoea has been shown to decrease the duration and severity of the diarrhoeal episode, diarrhoea hospitalization rates and, in some studies, all-cause mortality. Using multiple outcome measures, we sought to estimate the effect of zinc for the treatment of diarrhoea on diarrhoea mortality and subsequent pneumonia mortality

Insulin-Like Peptides and the Target of Rapamycin Pathway Coordinately Regulate Blood Digestion and Egg Maturation in the Mosquito Aedes aegypti

Mosquitoes are insects that vector many serious pathogens to humans and other vertebrates. Most mosquitoes must feed on the blood of a vertebrate host to produce eggs. In turn, multiple cycles of blood feeding promote frequent contacts with hosts and make mosquitoes ideal disease vectors. Both hormonal and nutritional factors are involved in regulating egg development in the mosquito, Aedes aegypti. However, the processes that regulate digestion of the blood meal remain unclear.Here we report that insulin peptide 3 (ILP3) directly stimulated late phase trypsin-like gene expression in blood fed females. In vivo knockdown of the mosquito insulin receptor (MIR) by RNA interference (RNAi) delayed but did not fully inhibit trypsin-like gene expression in the midgut, ecdysteroid (ECD) production by ovaries, and vitellogenin (Vg) expression by the fat body. In contrast, in vivo treatment with double-stranded MIR RNA and rapamycin completely blocked egg production. In vitro experiments showed that amino acids did not simulate late phase trypsin-like gene expression in the midgut or ECD production by the ovaries. However, amino acids did enhance ILP3-mediated stimulation of trypsin-like gene expression and ECD production.Overall, our results indicate that ILPs from the brain synchronize blood meal digestion and amino acid availability with ovarian ECD production to maximize Vg expression by the fat body. The activation of digestion by ILPs may also underlie the growth promoting effects of insulin and TOR signaling in other species
