Assessing Functional Capacity in Myalgic Encephalopathy/Chronic Fatigue Syndrome: A Patient-Informed Questionnaire.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is an acquired disease with significant morbidity that affects both children and adults. Post-exertional malaise is a cardinal symptom of ME/CFS and impacts a patient's functional capacity (FC). The absence of effective tools to assess FC has significant consequences for timely diagnosis, clinical follow-up, assessments for patient disability benefits, and research studies.

Severe and Very Severe Myalgic Encephalopathy/Chronic Fatigue Syndrome ME/CFS in Norway: Symptom Burden and Access to Care.

There is a striking lack of systematic knowledge regarding the symptom burden, capacity for activities of daily living, and supportive measures for the most severely ill ME/CFS patients. The present study seeks to address this through a national, Internet-based survey targeting patients with severe and very severe ME/CFS and their carers. Responses from 491 patients were included, with 444 having severe and 47 very severe ME/CFS with the classification based on the best estimate from patient responses.

A map of metabolic phenotypes in patients with myalgic encephalomyelitis/chronic fatigue syndrome.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating disease usually presenting after infection. Emerging evidence supports that energy metabolism is affected in ME/CFS, but a unifying metabolic phenotype has not been firmly established. We performed global metabolomics, lipidomics, and hormone measurements, and we used exploratory data analyses to compare serum from 83 patients with ME/CFS and 35 healthy controls.

Development and predictors of childhood mental health problems in former extremely preterm infants.

Objective: To investigate development and predictors of mental health problems from five to eleven years of age in children born extremely preterm (EP).

Method: In a national Norwegian cohort of children born before a gestational age of 28 weeks or with a birthweight <1000 g mental health was assessed by parents at five and eleven years of age using The Strengths and Difficulties Questionnaire. A Total Difficulties Score ≥ 90th percentile (TDS90) for a reference group was used as a measure of a mental health problem.

Mental health assessed by the Strengths and Difficulties Questionnaire for children born extremely preterm without severe disabilities at 11 years of age: a Norwegian, national population-based study.

The aims were to investigate mental health problems with the Strength and Difficulties Questionnaire (SDQ) in children born extremely preterm/extremely low birth weight (EP/ELBW) without severe disabilities compared to controls, and to identify peri-, or neonatal factors possibly predicting later mental health problems. A national Norwegian cohort of 11-year-old EP/ELBW children, excluding those with intellectual disabilities, non-ambulatory cerebral palsy, blindness and/or deafness, was assessed. Parents and teachers completed the SDQ.

Metabolic profiling indicates impaired pyruvate dehydrogenase function in myalgic encephalopathy/chronic fatigue syndrome.

Myalgic encephalopathy/chronic fatigue syndrome (ME/CFS) is a debilitating disease of unknown etiology, with hallmark symptoms including postexertional malaise and poor recovery. Metabolic dysfunction is a plausible contributing factor. We hypothesized that changes in serum amino acids may disclose specific defects in energy metabolism in ME/CFS.

Mental Health in Children Born Extremely Preterm Without Severe Neurodevelopmental Disabilities.

Objective: To describe the prevalence and gender characteristics of mental health problems in extremely preterm/extremely low birth weight (EP/ELBW) children without intellectual disabilities, blindness, deafness, or severe cerebral palsy compared with a reference group at 11 years of age.

Methods: In a national cohort of EP/ELBW children, mental health was assessed by parental and teacher report by using the Autism Spectrum Screening Questionnaire, the Swanson, Noland, and Pelham Questionnaire IV (attention-deficit/hyperactivity disorder), the Screen for Child Anxiety Related Emotional Disorders, symptoms of obsessive-compulsive disorder (OCD), and a total difficulties score from the Strength and Difficulties Questionnaire. Pervasive rating was defined as both parent and teacher scoring the child ≥95th percentile (≥90th percentile for total difficulties score) of the reference group, which was the population-based Bergen Child Study.

Foetal Doppler abnormality is associated with increased risk of sepsis and necrotising enterocolitis in preterm infants.

Aim: Fetoplacental Doppler abnormalities have been associated with increased neonatal mortality and morbidity. This study evaluated the associations between prenatal Doppler assessments and neonatal mortality and morbidity in premature infants born small for gestational age or after pre-eclampsia.

Methods: This was a population-based study of infants born alive at 22(0) -33(6) weeks of gestation, a birthweight <10th percentile for gestational age and/or maternal pre-eclampsia.

Minor neurodevelopmental impairments are associated with increased occurrence of ADHD symptoms in children born extremely preterm.

ADHD is more common in children born preterm than at term. The purpose of the study was to examine if, and to what extent, ADHD symptoms are associated with minor neurodevelopmental impairments (NDI) in extremely preterm children. In a national population-based cohort with gestational age 22-27 weeks or birth weight <1,000 g assessed at 5 years of age, scores on Yale Children's Inventory (YCI) scales (seven scales) were related to normal functions vs.

Foetal umbilical artery Doppler in small preterms: (IQ) neurocognitive outcome at 5 years of age.

Aim: To investigate whether absent or reversed end-diastolic flow in the umbilical artery (AREDF) is associated with neonatal mortality, morbidity or long-term neurocognitive outcome in extremely preterm infants exposed to preeclampsia or intrauterine growth restriction.

Methods: Prenatal Doppler data were retrospectively collected for liveborn infants with gestational age (GA) <28 weeks or birth weight (BW) <1000 g, born small for gestational age (SGA- BW <5th percentile for GA) or of mothers with preeclampsia at the four largest university hospitals in Norway during 1999-2000. Neonatal mortality and morbidities, cerebral palsy (CP) and IQ at 5 years of age were compared for infants with or without AREDF.

Prediction of outcome at 5 years from assessments at 2 years among extremely preterm children: a Norwegian national cohort study.

Aim: To examine the predictive value of early assessments on developmental outcome at 5 years in children born extremely preterm.

Methods: This is a prospective observational study of all infants born in Norway in 1999-2000 with gestational age (GA) <28 weeks or birth weight (BW) <1000 g. At 2 years of age, paediatricians assessed mental and motor development from milestones.

Neonatal mortality and morbidity in extremely preterm small for gestational age infants: a population based study.

Aim: To assess if growth restricted (small for gestational age, SGA) extremely preterm infants have excess neonatal mortality and morbidity.

Methods: This was a cohort study of all infants born alive at 22-27 weeks' post menstrual age in Norway during 1999-2000. Outcomes were compared between those who were SGA, defined as a birth weight less than the fifth percentile for post menstrual age, and those who had weights at or above the fifth percentile.

The combined burden of cognitive, executive function, and psychosocial problems in children with epilepsy: a population-based study.

The combined burden of psychosocial (Achenbach scales), cognitive (Raven matrices), and executive function (EF) problems was studied in a population-based sample of 6- to 12-year-old children with epilepsy (n=162; 99 males, 63 females) and in an age- and sex-matched control group (n=107; 62 males, 45 females). Approximately 35% of the children with epilepsy had severe non-verbal cognitive problems. In those that did not, mild cognitive problems (26% vs 11%, p=0.

Severe fascioscapulohumeral muscular dystrophy presenting with Coats' disease and mental retardation.

We describe two Norwegian children with fascioscapulohumeral muscular dystrophy in whom Coats' disease, deafness, mental retardation and possible epilepsy were the presenting features. The children have a 4q35 deletion giving a small residual repeat fragment that they have inherited from their father who is a mosaic. Fundal changes consistent with bilateral Coats' disease were found in both children.

Executive functions and seizure-related factors in children with epilepsy in Western Norway.

Executive functions (EFs), seizure-related factors, and school performance were studied in a population-based sample of children with epilepsy (n=117; 71 males, 46 females; mean age 10y 5mo [SD 2y]; range 6y-12y 11mo) and a comparison group (n=124; 71 males, 53 females; mean age 10y 1mo [SD 2y 1mo]; range 6y-12y 11mo). EF, cognitive function, depression, socioeconomic status, and school performance were examined. Patients with epilepsy performed significantly lower than the comparison group on all EF measures except incidental memory.

Co-existing symptoms and risk factors among African school children with hyperactivity-inattention symptoms in Kinshasa, Congo.

Unlabelled: The aims of the study were to explore hyperactivity-inattention (HI) symptoms and co-existing symptoms of emotional and behavioural problems among African school children and their relationship with health status, socio-demographic factors, and school performance.

Method: A case-control approach was used. The Strengths and Difficulties Questionnaire (SDQ) was used to explore the co-existing emotional and behavioural symptoms and a semi-structured interview with parents to explore the socio-demographic variables.

Psychosocial problems and seizure-related factors in children with epilepsy.

In this study we describe psychosocial functions and seizure-related factors in a population-based sample of children with epilepsy. Psychosocial problems (Achenbach scales), cognitive function, and socioeconomic status were studied in 117 children with epilepsy aged between 6 and 13 years (mean age 11y [SD 2y 1mo] and 10y 8mo [SD 2y]; 71 males, 46 females) and in randomly selected controls matched with 117 children for sex and age (mean age 11y 2mo [SD 2y 1mo] and 10y 5mo [SD 2y 4mo]; 69 males, 48 females). The children had partial (n=67), generalized (n=43), or undetermined (n=7) epilepsy syndromes, and partial (n=68), generalized (n=47), or other (n=2) main seizure types.

Maternal signs of chorioamnionitis: persistent cognitive impairment in low-birthweight children.

Aim: To examine whether chorioamnionitis (CA) is associated with long-term cognitive impairment in low-birthweight (LBW) children without major handicaps such as cerebral palsy.

Methods: Population-based long-term follow-up study at 11 y of age of 130 LBW children with birthweight less than 2,000 g, without major handicaps. Thirteen children with maternal signs of clinical CA were compared with the 117 LBW children without.

Shunt revisions in children--can they be avoided? Experiences from a population-based study.

Background: Shunt failure is by far the most frequent problem in children with shunts, and most of them will experience this condition at some point in their lives. In order to identify causes of shunt failure, and to compare multi-component and one-piece shunt systems, we analyzed retrospectively all pediatric shunt procedures in our Department during an 11-year period. The study does not deal with shunt infections.

A non-handicapped cohort of low-birthweight children: growth and general health status at 11 years of age.

Aims: To describe and compare physical growth, current health status, functional limitations and neurodevelopmental impairments (defined as low IQ, school problems or psychiatric disorder) at 11 y of age in a population of non-handicapped low-birthweight (LBW) children with that of normal-birthweight (NBW) children.

Methods: A population-based sample of 130 LBW children (weighing less than 2000 g at birth) without major handicaps, and a random sample of 131 NBW children born at term. Somatic and mental health and cognitive abilities were assessed through questionnaires to parents, a physical examination, standardized tests of cognitive function (WISC-R) and a semi-structured interview (Children Assessment Schedule).

Attention deficit and hyperactivity disorder among school children in Kinshasa, Democratic Republic of Congo.

Objectives: To estimate the prevalence and determinants of attention deficit and hyperactivity disorder (ADHD) symptoms among school children in Kinshasa, an African urban setting.

Methods: The 18-items of the Disruptive Behaviour Disorder rating scale (DBD), which is based on the Diagnostic and Statistical Manual for mental disorders 4(th) edition (DSM-IV), were used to investigate the presence of ADHD symptoms. Parents interviews, using a questionnaire specially designed for the study, were performed to identify socio-demographic characteristics.

Cognition in African children with attention-deficit hyperactivity disorder.

The aims of the study were: (1) to describe the performance of African children with symptoms of attention-deficit hyperactivity disorder on selected neuropsychologic tests and compare it with performance among peers of the same age without symptoms; (2) to explore through a factor analysis if the selected tests cover the same functions as known from studies in Europe and North America. A nested case-control approach was used to select the two groups of children. The tests were selected to measure aspects of executive functions, attention and memory functions as well as motor skills.
