Motor and executive function at 6 years of age after extremely preterm birth

BACKGROUND. Studies of very preterm infants have demonstrated impairments in multiple neurocognitive domains. We hypothesized that neuromotor and executive- function deficits may independently contribute to school failure. METHODS.We studied children who were born at 25 completed weeks’ gestation in the United Kingdom and Ireland in 1995 at early school age. Children underwent standardized cognitive and neuromotor assessments, including the Kaufman Assessment Battery for Children and NEPSY, and a teacher-based assessment of academic achievement. RESULTS. Of 308 surviving children, 241 (78%) were assessed at a median age of 6 years 4 months. Compared with 160 term classmates, 180 extremely preterm children without cerebral palsy and attending mainstream school performed less well on 3 simple motor tasks: posting coins, heel walking, and 1-leg standing. They more frequently had non–right-hand preferences (28% vs 10%) and more associated/ overflow movements during motor tasks. Standardized scores for visuospatial and sensorimotor function performance differed from classmates by 1.6 and 1.1 SDs of the classmates’ scores, respectively. These differences attenuated but remained significant after controlling for overall cognitive scores. Cognitive, visuospatial scores, and motor scores explained 54% of the variance in teachers’ ratings of performance in the whole set; in the extremely preterm group, additional variance was explained by attention-executive tasks and gender. CONCLUSIONS. Impairment of motor, visuospatial, and sensorimotor function, including planning, self-regulation, inhibition, and motor persistence, contributes excess morbidity over cognitive impairment in extremely preterm children and contributes independently to poor classroom performance at 6 years of age

The EPICure study : growth and blood pressure at 6 years of age following extremely preterm birth

Background: Preterm children are at risk for reduced growth in early childhood, which may predispose them to later changes in blood pressure. We studied growth and blood pressure (BP) in extremely preterm (EP) children at age 6 years. Methods: We evaluated children who were born at 25 completed weeks of gestation or less in the United Kingdom and Ireland in 1995 when they reached early school age. Children underwent standardized assessments, including auxology and sitting blood pressure. Results: Of 308 surviving children, 241 (78 percent) were assessed at a median age of 6 years 4 months; 160 full term classmates acted as a comparison group. Compared to classmates, EP children were 1.2 standard deviations (SD) lighter, 0.97SD shorter, BMI was 0.95SD lower and head circumference 1.3SD lower. Compared to 2.5 years of age, EP children showed catch up in terms of weight by 0.37SD, height by 0.42SD and head circumference by 0.13SD. Systolic and diastolic BP were lower by 2.3mmHg and 2.4mmHg respectively in EP children but these differences were accounted for by differences in height and BMI. Maternal smoking in pregnancy was associated with lower BP, children born before 24 weeks had higher systolic and children given postnatal steroids higher diastolic pressures. Conclusions: Poor postnatal growth seen after birth and at in the third year persists into school age. Catch up growth reduces some of the early deficit but is least for head growth. Despite serious postnatal growth restriction blood pressure appears similar in both EP and term classmates

Screening for autism in preterm children : diagnostic utility of the Social Communication Questionnaire

Objective Preterm survivors are at high risk for autism spectrum disorders (ASD). The diagnostic utility of the Social Communication Questionnaire (SCQ) in screening for ASD was assessed in extremely preterm children at 11 years of age. Design All babies born at <26 weeks gestation in UK and Ireland from March through December 1995 were recruited to the EPICure Study. Of 307 survivors, 219 (71%) were assessed at 11 years. Parents of 173 children completed the SCQ to screen for autistic features and the Development and Well Being Assessment (DAWBA) psychiatric interview. A consensus diagnosis of ASD was assigned by two child psychiatrists following review of the DAWBA parental interview and corresponding DAWBA teacher questionnaire. Setting Community-based follow-up. Results Using the established SCQ cut-off (scores ≥15), 28 (16%) extremely preterm children screened positive for ASD. Eleven (6%) were assigned a diagnosis of ASD. Using this cut-off, the SCQ had 82% sensitivity and 88% specifi city for identifying ASD in this population. Using a receiver operating characteristic curve, SCQ scores ≥14 had optimal diagnostic utility (area under curve: 0.94; sensitivity: 91%; specifi city: 86%). Positive predictive value was relatively low (31%) resulting in numerous over-referrals. However, children with false positive screens had signifi cantly worse neuro-developmental, cognitive and behavioural outcomes than those with true negative screens. Conclusion The SCQ has good diagnostic utility for identifying ASD in extremely preterm children and is a useful screening tool in this population. Children with false positive screens represent a high-risk group in whom further diagnostic assessment would be benefi cial

Academic attainment and special educational needs in extremely preterm children at 11 years of age : the EPICure Study

Aim: To assess academic attainment and special educational needs (SEN) in extremely preterm (EP) children in middle childhood. Methods: Of 307 EP (=25 weeks) survivors born in the UK and Ireland in 1995, 219 (71%) were re-assessed at 11 years, with a comparison group of 153 classmates born at term, using standardised tests of cognitive ability and academic attainment and teacher reports of school performance and special educational needs (SEN). Multiple imputation was used to correct for selective dropout. Results: EP children had significantly lower scores than classmates for cognitive ability (-20 points; 95%CI: -23,-17), reading (-18 points; -22,-15) and mathematics (-27 points; -31,-23). Twenty-nine (13%) EP children attended special school. In mainstream schools, 105 (57%) EP children had SEN (OR: 10; 6, 18) and 103 (55%) required SEN resource provision (OR: 10; 5, 18). Teachers rated 50% of EP children with attainment below the average range compared with 5% of classmates (OR: 18; CI: 8, 41). EP children who are entered for mainstream education an academic year early due to preterm birth had similar academic attainment but required more SEN support (OR: 2; 1.1,3.8). Conclusions: EP survivors remain at high risk for learning impairments and poor academic attainment in middle childhood. A significant proportion require full-time specialist education and over half of those attending mainstream schools require additional health or educational resources in order to access the national curriculum. The prevalence and impact of SEN is likely to increase as these children approach the transition to secondary school. -------------------------------------------------------------------------------

Educational outcomes in extremely preterm children : neuropsychological correlates and predictors of attainment

This study assessed the impact of extremely preterm birth on academic attainment at 11 years of age, investigated neuropsychological antecedents of attainment in reading and mathematics, and examined early predictors of educational outcomes. Children born extremely preterm had significantly poorer academic attainment and a higher prevalence of learning difficulties than their term peers. General cognitive ability and specific deficits in visuospatial skills or phoneme deletion at 6 years were predictive of mathematics and reading attainment at 11 years in both extremely preterm and term children. Phonological processing, attention, and executive functions at 6 years were also associated with academic attainment in children born extremely preterm. Furthermore, social factors, neonatal factors (necrotizing enterocolitis, breech delivery, abnormal cerebral ultrasound, early breast milk provision), and developmental factors at 30 months (head circumference, cognitive development), were independent predictors of educational outcomes at 11 years. Neonatal complications combined with assessments of early cognitive function provide moderate prediction for educational outcomes in children born extremely preterm

Autism spectrum disorders in extremely preterm children

Objectives To investigate the prevalence, correlates, and antecedents of autism spectrum disorders (ASD) in extremely preterm children. Study design We conducted a prospective study of all births <26 weeks gestation in the United Kingdom and Ireland in 1995. Of 307 survivors at 11 years, 219 (71%) were assessed and compared with 153 term-born classmates. Parents completed the Social Communication Questionnaire (SCQ) to assess autism spectrum symptoms, and ASD were diagnosed by using a psychiatric evaluation. An IQ test and clinical evaluation were also administered. Longitudinal outcome data were available for extremely preterm children. Results Extremely preterm children had significantly higher SCQ scores than classmates (mean difference, 4.6 points; 95% CI, 3.4-5.8). Sixteen extremely preterm children (8%) were assigned an ASD diagnosis, compared with none of the classmates. By hospital discharge, male sex, lower gestation, vaginal breech delivery, abnormal cerebral ultrasound scanning results, and not having had breast milk were independently associated with autism spectrum symptoms. By 6 years, independent associates were cognitive impairment, inattention and peer problems, withdrawn behavior at 2.5 years, and not having had breast milk. Conclusions Extremely preterm children are at increased risk for autism spectrum symptoms and ASD in middle childhood. These symptoms and disorders were associated with neurocognitive outcomes, suggesting that ASD may result from abnormal brain development in this population

TOIB Study. Are topical or oral ibuprofen equally effective for the treatment of chronic knee pain presenting in primary care: a randomised controlled trial with patient preference study. [ISRCTN79353052]

BACKGROUND: Many older people have chronic knee pain. Both topical and oral non- steroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat this. Oral NSAIDS are effective, at least in the short term, but can have severe adverse effects. Topical NSAIDs also appear to be effective, at least in the short term. One might expect topical NSAIDs both to be less effective and to have fewer adverse effects than oral NSAIDs. If topical NSAIDs have fewer adverse effects this may outweigh both the reduction in effectiveness and the higher cost of topical compared to oral treatment. Patient preferences may influence the comparative effectiveness of drugs delivered via different routes. METHODS: TOIB is a randomised trial comparing topical and oral ibuprofen, with a parallel patient preference study. We are recruiting people aged 50 or over with chronic knee pain, from 27 MRC General Practice Research Framework practices across the UK. We are seeking to recruit 283 participants to the RCT and 379 to the PPS. Participants will be followed up for up to two years (with the majority reaching one year). Outcomes will be assessed by postal questionnaire, nurse examination, laboratory tests and medical record searches at one and two years or the end of the study. DISCUSSION: This study will provide new evidence on the overall costs and benefits of treating chronic knee pain with either oral or topical ibuprofen. The use of a patient preference design is unusual, but will allow us to explore how preference influences response to a medication. In addition, it will provide more information on adverse events. This study will provide evidence to inform primary care practitioners, and possibly influence practice

The experience of foot problems and decisions to access foot care in patients with rheumatoid arthritis: A qualitative study

© 2017 The Author(s). Background: Although foot problems are common in rheumatoid arthritis (RA), the consequences of foot problems from the patient perspective have not been fully explored. The aims of this study were to explore the experience of foot problems and decisions to access foot care services or not in patients with RA. Methods: Semi structured, one-to-one interviews with patients recruited from 2 UK rheumatology units, purposively sampled for self-reported foot problems and a range of personal/disease characteristics. Inductive thematic analysis was used, with rigour provided by multiple independent analysers. Emerging themes were discussed and agreed by all authors. Results: Twelve patients participated: 7 female mean age 56 years (29-72); mean disease duration 12 years (2-27), 5 had accessed foot care services. The 'Impact' of foot problems was substantial and formed the underpinning theme, comprising three organising themes: 'Foot symptoms'; 'Consequences'; and 'Cost'. Foot symptoms such as pain and numbness required self-management, and affected daily life (walking, working) leading to social and emotional costs. The global theme, 'Decision to access foot care or not', also comprised three organising themes: 'Access perceived unnecessary' (no problem, can cope); 'Access hindered by patients' perception'; and 'Access supported by patient and clinician'. Decisions to access foot care or not were complex and influenced by patient beliefs regarding possible treatments and how to access these, and hindered by patient perceptions that their feet were ignored by rheumatology clinicians. Positive experience of foot care encouraged continued utilisation but negative experiences contributed to patients' decisions to discontinue foot care services. Conclusions: Foot problems are important issues for patients and impact on many aspects of their physical, social and emotional lives. Patients who had accessed foot care services prioritised their foot problems as an important health care need. However, for others who would like foot care services, personal knowledge and values, and perceived barriers in clinical practice, appear to interact to inhibit foot care access. The extent which these interactions affect overall access to foot care in RA patients in general now needs to be quantified to help to inform and improve the effectiveness of the organisation and delivery of foot care
