Diagnosis, assessment and management of atopic dermatitis in children with skin of colour.

BACKGROUND: It is important to be able to manage patients regardless of ethnicities. The understanding of skin diseases, including atopic dermatitis, in patients with skin of colour (SOC) is lagging compared with that in patients with lighter skin and has been identified as an educational gap among medical practitioners. OBJECTIVE: This paper synthesises the latest literature on the diagnosis, assessment, treatment outcomes and cultural considerations for managing atopic dermatitis in children with SOC in the general practice setting. DISCUSSION: Atopic dermatitis in children with SOC can vary from traditional descriptions and appear psoriasiform, lichenoid, scaly, papular, hypopigmented or violaceous. It can be misdiagnosed and its severity underestimated. Complications from atopic dermatitis, as well as the treatments provided, might result in inadequate treatment unless the treating doctor is aware of specific nuances in children with SOC.

Design and Development of Magnetostrictive Actuators and Sensors for Structural Health Monitoring.

Carbon Fibre Reinforced Polymer composite (CFRP) is widely used in the aerospace industry, but is prone to delamination, which is a major causes of failure. Structural Health Monitoring (SHM) systems need to be developed to determine the damage occurring within it. Our motivation is to design cost-effective new sensors and a data acquisition system for magnetostrictive structural health monitoring of aerospace composites using a simple RLC circuit. The developed system is tested on magnetostrictive FeSiB and CoSiB actuator ribbons using a bending rig. Our results show detectable sensitivity of inductors as low as 0.6 µH for a bending rig radii between 600 to 300 mm (equivalent to 0.8 to 1.7 mStrain), which show a strain sensitivity resolution of 0.01 µStrain (surface area: ~36 mm2). This value is at the detectability limit of our fabricated system. The best resolution (1.86 µStrain) was obtained from a 70-turn copper (~64 µH) wire inductor (surface area: ~400 mm2) that was paired with a FeSiB actuator.

Cumulative psychosocial risk, parental socialization, and child cognitive functioning: A longitudinal cascade model.

Previous studies have demonstrated that various psychosocial risks are associated with poor cognitive functioning in children, and these risks frequently cluster together. In the current longitudinal study, we tested a model in which it was hypothesized that cumulative psychosocial adversity of mothers would have deleterious effects on children's cognitive functioning by compromising socialization processes within families (i.e., parental competence). A prospective community birth cohort of 501 families was recruited when children were newborns. At this time, mothers reported on their current psychosocial circumstances (socioeconomic status, teen parenthood, depression, etc.), which were summed into a cumulative risk score. Families were followed up at 18 months and 3 years, at which point maternal reflective capacity and cognitive sensitivity were measured, respectively. Child cognition (executive functioning, theory of mind, and language ability) was assessed at age 4.5 using age-appropriate observational and standardized tasks. Analyses controlled for child age, gender, number of children in the home, number of years married, and mothers' history of adversity. The results revealed significant declines in child cognition as well as maternal reflective capacity and cognitive sensitivity as the number of psychosocial risks increased. Moreover, longitudinal path analysis showed significant indirect effects from cumulative risk to all three cognitive outcomes via reflective capacity and cognitive sensitivity. Findings suggest that cumulative risk of mothers may partially account for child cognitive difficulties in various domains by disrupting key parental socialization competencies.

Behavioral Risk Assessment From Newborn to Preschool: The Value of Older Siblings.

OBJECTIVES: The aim of this study was to examine the plausibility of a risk prediction tool in infancy for school-entry emotional and behavioral problems. Familial aggregation has been operationalized previously as maternal psychopathology. The hypothesis was tested that older sibling (OS) psychopathology, as an indicator of familial aggregation, would enable a fair level of risk prediction compared with previous research, when combined with traditional risk factors. METHODS: By using a longitudinal design, data on child and family risk factors were collected on 323 infants (M = 2.00 months), all of whom had OSs. Infants were followed up 4.5 years later when both parents provided ratings of emotional and behavioral problems. Multiple regression and receiver operating characteristic curve analyses were conducted for emotional, conduct, and attention problems separately. RESULTS: The emotional and behavioral problems of OSs at infancy were the strongest predictors of the same problems in target children 4.5 years later. Other risk factors, including maternal depression and socioeconomic status provided extra, but weak, significant prediction. The area under the receiver operating characteristic curve for emotional and conduct problems yielded a fair prediction. CONCLUSIONS: This study is the first to offer a fair degree of prediction from risk factors at birth to school-entry emotional and behavioral problems. This degree of prediction was achieved with the inclusion of the emotional and behavioral problems of OSs (thus limiting generalizability to children with OSs). The inclusion of OS psychopathology raises risk prediction to a fair level.
