The health of children and young people with cerebral palsy: a longitudinal, population-based study

Salivary alpha amylase and cortisol levels as stress biomarkers in children with cerebral palsy and their association with a physical therapy program

INTRODUCTION

Cerebral palsy (CP) is one of the main causes of physical disabilities in childhood. There is evidence that CP children display high levels of stress, which could interfere with learning processes and interpretation of relevant sensory information during motor skills acquisition and socialization.

OBJECTIVE

This study aims to compare basal levels of stress biomarkers (cortisol and alpha-amylase) of healthy children (HC) and children with CP, and to investigate whether a physical therapy session using the neurodevelopmental technique (NDT) interferes with these levels.

METHODS

A cross-sectional design was used. A total of 86 children (HC: n = 45 and CP: n = 41) with matching age, sex, socioeconomic status, and sampling time. Salivary cortisol and alpha-amylase levels were measured by means of electrochemiluminescence and spectrophotometry methods. A single saliva sample was collected in the HC group to determine basal levels. For CP group three samples were collected: a first sample was taken 20-30 min prior to the intervention, while two post-intervention samples were collected (5 and 20 min) to evaluate individual changes in salivary stress biomarkers.

RESULTS

Higher basal cortisol concentration was found in CP children when compared to HC group. Moreover, CP children showed a significant reduction in cortisol levels 20 min after NDT intervention. No significant differences were observed in alpha-amylase values.

CONCLUSION

Present results show that CP causes alteration in basal cortisol values at childhood and suggest that CP children respond to environmental regulatory factors such as NDT, in attempt to reduce stress.

Características epidemiológicas da paralisia cerebral em crianças e adolescentes em uma capital do nordeste brasileiro

RESUMO O objetivo deste estudo foi descrever a prevalência de paralisia cerebral entre crianças e adolescentes, seus subtipos, as possíveis comorbidades e as características socioeconômicas das famílias. Foi realizado um estudo epidemiológico do tipo transversal a partir de um inquérito de base populacional sobre a paralisia cerebral em crianças e adolescentes na cidade de Aracaju (SE), Brasil. O estudo obteve informações sobre 240 crianças e adolescentes com paralisia cerebral a partir das respostas a um questionário feitas por seus responsáveis. Foi encontrada a prevalência de período de 1,37 em cada mil. Alguns bairros possuem prevalência de três a quatro vezes maior, revelando que a taxa de prevalência total não é um indicador homogêneo. A maioria dos participantes foi do sexo masculino (56,25%), de raça/cor declarada como parda ou preta (67,50%), sendo que a média de idade foi de 8,56 anos. A paralisia cerebral de tipo espástica bilateral foi a mais frequente (45,42%) e a comorbidade referida na maioria dos casos foi a epilepsia (48,33%). A renda familiar mensal correspondia a $252,87 dólares. O estudo revelou que as crianças e adolescentes com paralisia cerebral são, em grande parte, pertencentes a minorias sociais, de raça/cor parda ou preta, e suas famílias vivem na linha da extrema pobreza.

Tissue Injury and Astrocytic Reaction, But Not Cognitive Deficits, Are Dependent on Hypoxia Duration in Very Immature Rats Undergoing Neonatal Hypoxia-Ischemia

Preterm birth and hypoxia-ischemia (HI) are major causes of neonatal death and neurological disabilities in newborns. The widely used preclinical HI model combines carotid occlusion with hypoxia exposure; however, the relationship between different hypoxia exposure periods with brain tissue loss, astrocyte reactivity and behavioral impairments following HI is lacking. Present study evaluated HI-induced behavioral and morphological consequences in rats exposed to different periods of hypoxia at postnatal day 3. Wistar rats of both sexes were assigned into four groups: control group, HI-120 min, HI-180 min and HI-210 min. Neurodevelopmental reflexes, exploratory abilities and cognitive function were assessed. At adulthood, tissue damage and reactive astrogliosis were measured. Animals exposed to HI-180 and HI-210 min had delayed neurodevelopmental reflexes compared to control group. Histological assessment showed tissue loss that was restricted to the ipsilateral hemisphere in lower periods of hypoxia exposure (120 and 180 min) but affected both hemispheres when 210 min was used. Reactive astrogliosis was increased only after 210 min of hypoxia. Interestingly, cognitive deficits were induced regardless the duration of hypoxia and there were correlations between behavioral parameters and cortex, hippocampus and corpus callosum volumes. These results show the duration of hypoxia has a close relationship with astrocytic response and tissue damage progression. Furthermore, the long-lasting cognitive memory deficit and its association with brain structures beyond the hippocampus suggests that complex anatomical changes should be involved in functional alterations taking place as hypoxia duration is increased, even when the cognitive impairment limit is achieved.

Quality of life in children and adolescents with cerebral palsy: a systematic review with meta-analysis

BACKGROUND

Cerebral palsy has been linked to decreased quality of life. However use of self- versus proxy-perspectives and norm-sample comparisons to examine quality of life impact may produce different results.

AIMS

To compare quality of life ratings in children and adolescents with cerebral palsy relative to typically developing peers in consideration of sample and methodological moderators on estimated effects.

METHODS

Eleven independent studies, comprising a pooled sample of 1475 families living with cerebral palsy and 42119 peers, were identified. Study reporting quality was evaluated with the QualSyst tool and standardised mean group differences (Hedges' g) with associated confidence intervals and p values calculated. Heterogeneity was examined using a random effects model.

RESULTS

All studies provided good to excellent methodological and statistical detail. Physical quality of life was significantly impaired among those with cerebral palsy (g range: -0.42 to -1.58). However, inconsistent findings were noted in relation to the effect of cerebral palsy on psychological (g range: 0.04 to -0.80) and social quality of life (g range: -0.80 to -0.51), depending on the measurement used. There was a trend for parents to evaluate their child's physical quality of life lower than child-reported scores.

CONCLUSIONS

Physical quality of life is, invariably, more affected in those with cerebral palsy. The connection between cerebral palsy and psychosocial quality of life is less clear. Noted parent-child discrepancies highlight the value of a multi-informant approach to child quality of life assessment. Implications for rehabilitation Quality of life is an important health-related outcome in cerebral palsy research and practice. Collecting both self-report and proxy data can help to highlight quality of life issues that are salient to the parent and to the child or adolescent with cerebral palsy. Selection of the appropriate quality of life instrument depends on the assessment purpose, with available measures varying in their focus on functionality, subjectivity and illness-specific items. Quality of life assessment of children with cerebral palsy should extend beyond functional abilities to include less obvious, but critical, psychological and social issues.

Prevalence and characteristics of pain in children and young adults with cerebral palsy: a systematic review

AIM

The primary aim of this review is to evaluate the evidence for pain prevalence in children and young adults with cerebral palsy. Secondary aims are to identify pain characteristics and types of pain measurement used in this population.

METHOD

Ovid MEDLINE, Embase, CINAHL Plus, and PubMed were searched in October 2016 and updated in November 2017. Two authors independently screened studies according to Preferred Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Pain outcomes were categorized within a biopsychosocial pain framework, with pain prevalence extracted for all recall periods and measurement types.

RESULTS

One hundred and six publications from 57 studies met inclusion criteria. Pain prevalence varied widely from 14 per cent to 76 per cent and was higher in females, older age groups, and those classified within Gross Motor Function Classification System level V. Pain was most frequent in the lower limbs, back, and abdomen and associated with reduced quality of life or health status. The influence of pain on psychological functioning, interference, and participation was inconclusive.

INTERPRETATION

Variation exists in reported pain prevalence because of sampling bias, inconsistent measurement, varying recall periods, and use of different participant age ranges.

WHAT THIS PAPER ADDS

Pain prevalence varies from 14 per cent to 76 per cent in children and young adults with cerebral palsy. Pain is more prevalent in females, older age groups, and children in Gross Motor Function Classification System level V.

Morphofunctional characteristics of skeletal muscle in rats with cerebral palsy

Knowledge of skeletal muscle adaptations is important to understand the functional deficits in cerebral palsy (CP). This study aimed to investigate the morphofunctional characteristics of skeletal muscle in a CP animal model. Initially, pregnant Wistar rats were injected intraperitoneally with saline or lipopolysaccharide over the last five days of pregnancy. The control group (n = 8) consisted of male pups born to females injected with saline. The CP group (n = 8) consisted of male pups born to females injected with lipopolysaccharide, which were submitted to perinatal anoxia [day of birth, postnatal day 0 (P0)] and sensorimotor restriction (P1-P30). The open-field test was undertaken on P29 and P45. On P48, the animals were weighed, and the plantaris muscle was collected and its weight and length were measured. Transverse sections were stained with haematoxylin-eosin, NADH-TR, Masson's trichrome and non-specific esterase reaction for analysis. and transmission electron microscopy was performed. In the CP group, reductions were observed in mobility time, number of crossings and rearing frequency, body weight, muscle weight and length, and nucleus-to-fibre and capillary-to-fibre ratios. There was a statistically significant increase in the percentage area of the muscle section occupied by collagen; reduction in the area and increase in the number of type I muscle fibres; increase in myofibrillar disorganization and Z-line disorganization and dissolution; and reduction in the area and largest and smallest diameters of neuromuscular junctions. Thus this animal model of CP produced morphofunctional alterations in skeletal muscle, that were associated with evidence of motor deficits as demonstrated by the open-field test.

The risk, burden, and management of non-communicable diseases in cerebral palsy: a scoping review

AIM

To examine the risk, burden, and management of non-communicable diseases (NCDs) among people with cerebral palsy (CP).

METHOD

Databases (Ovid MEDLINE, Embase Ovid, CINAHL Plus) were systematically searched up to August 2017. Data on the prevalence of risk factors for, and the burden and management of, cardiovascular diseases, diabetes, cancers, and respiratory diseases were extracted.

RESULTS

Thirty-six studies that examined the prevalence of risk factors among people with CP were identified. There was inconsistent evidence that people with CP had higher prevalence of metabolic risk factors such as hypertension, hyperlipidaemia, and obesity, but strong evidence that they participated in low levels of physical activity, compared with people without CP. Seven studies reported on the burden of NCDs. Adults with CP had a higher risk of NCDs, including stroke, chronic obstructive pulmonary disease, and other heart conditions, and death due to NCDs, including cancers, chronic obstructive pulmonary disease, stroke, and ischaemic heart disease, compared with the general population. Only one study reported on the management of NCD, specifically the uptake of breast cancer screening among females.

INTERPRETATION

The burden of NCDs is higher among adults with CP compared with the general population. Further research is required to determine the prevalence of metabolic risk factors and management of NCDs among people with CP.

WHAT THIS PAPER ADDS

Adults with cerebral palsy (CP) have an increased risk of non-communicable diseases (NCDs) and increased risk of death because of NCDs. Evidence is inconsistent about the elevated prevalence of metabolic risk factors for NCDs. Evidence is consistent that people with CP participate in reduced physical activity. Only one study reported on management of NCD among people with CP. Available evidence suggests people with CP are less likely to receive preventive medicine.

Social participation of children age 8-12 with SLI

PURPOSE

Two objectives are being pursued: (1) to describe the level of social participation of children aged 8-12 presenting a specific language impairment (SLI) and (2) to identify personal and family factors associated with their level of social participation.

METHOD

This cross-sectional study was conducted among 29 children with SLI and one of their parents. Parental stress and family adversity were measured as risk factors. The measure of life habits (LIFE-H) adapted to children aged 5-3 was used to measure social participation.

RESULTS

The assumption that social participation of these children is impaired in relation to the communication dimension was generally confirmed. The statements referring to the "communication in the community" and "written communication" are those for which the results are weaker. "Communication at home" is made easier albeit with some difficulties, while "telecommunication" is totally preserved. A high level of parental stress is also confirmed, affecting the willingness of parents to support their child's autonomy.

CONCLUSIONS

The achievement of a normal lifestyle of children with SLI is upset in many spheres of life. Methods of intervention must better reflect the needs and realities experienced by these children in their various living environments, in order to optimize social participation, and consequently, to improve their well-being and that of their families. The need to develop strategies to develop children's independence and to reduce parental stress must be recognized and all stakeholders need to be engaged in the resolution of this challenge.

IMPLICATIONS FOR REHABILITATION

The realization of life habits of SLI children is compromised at various levels, especially in the domain related to "communication in the community" and "written communication". Speech-language pathologists must consider providing ongoing support throughout the primary years of these children and during adolescence, to promote and facilitate the continued realization of life habits of SLI persons. Providing ongoing support throughout the primary years and thereafter is needed to facilitate the continuing realization of life habits of SLI persons. Parents of children with SLI experience considerable stress in relation to the exercise of their parental roles. It is important to intervene and to support parents to promote autonomy for their SLI children.

Self-reported quality of life of adolescents with cerebral palsy: a cross-sectional and longitudinal analysis

BACKGROUND

Children with cerebral palsy who can self-report have similar quality of life (QoL) to their able-bodied peers. Is this similarity also found in adolescence? We examined how self-reported QoL of adolescents with cerebral palsy varies with impairment and compares with the general population, and how factors in childhood predict adolescent QoL.

METHODS

We report QoL outcomes in a longitudinal follow-up and cross-sectional analysis of individuals included in the SPARCLE1 (childhood) and SPARCLE2 (adolescent) studies. In 2004 (SPARCLE1), a cohort of 818 children aged 8-12 years were randomly selected from population-based cerebral palsy registers in nine European regions. We gathered data from 500 participants about QoL with KIDSCREEN (ten domains); frequency of pain; child psychological problems (Strengths and Difficulties Questionnaire); and parenting stress (Parenting Stress Index). At follow-up in 2009 (SPARCLE2), 355 (71%) adolescents aged 13-17 years remained in the study and self-reported QoL (longitudinal sample). 76 additional adolescents self-reported QoL in 2009, providing data for 431 adolescents in the cross-sectional sample. Researchers gathered data at home visits. We compared QoL against matched controls in the general population. We used multivariable regression to relate QoL of adolescents with cerebral palsy to impairments (cross-sectional analysis) and to childhood QoL, pain, psychological problems, and parenting stress (longitudinal analysis).

FINDINGS

Severity of impairment was significantly associated (p<0·01) with reduced adolescent QoL on only three domains (Moods and emotions, Autonomy, and Social support and peers); average differences in QoL between the least and most able groups were generally less than 0·5 SD. Adolescents with cerebral palsy had significantly lower QoL than did those in the general population in only one domain (Social support and peers; mean difference -2·7 [0·25 SD], 95% CI -4·3 to -1·4). Pain in childhood or adolescence was strongly associated with low adolescent QoL on eight domains. Childhood QoL was a consistent predictor of adolescent QoL. Child psychological problems and parenting stress in childhood or their worsening between childhood and adolescence predicted only small reductions in adolescent QoL.

INTERPRETATION

Individual and societal attitudes should be affected by the similarity of the QoL of adolescents with and without cerebral palsy. Adolescents with cerebral palsy need particular help to maintain and develop peer relationships. Interventions in childhood to alleviate psychological difficulties, parenting stress, and especially pain, are justified for their intrinsic value and for their longer term effect on adolescent QoL.

Health-related quality of life of children with physical disabilities: a longitudinal study

BACKGROUND

Outcomes of health and rehabilitation services for children and youth with disabilities increasingly include assessments of health-related quality of life (HRQoL). The purpose of this research was to 1) describe overall patterns of HRQoL, 2) examine changes in parent's perceptions of child's HRQoL across 18 months and 3) explore factors that predict these changes.

METHODS

Participants in this study included 427 parents of children (229 boys and 198 girls) with a physically-based disability between the ages of 6 to 14 years. The Child Health Questionnaire (CHQ) was administered three times, at nine month intervals. Comparisons to the CHQ normative data were analyzed at Time 1 using t-tests, and change over time was examined using linear mixed-effects models. Possible predictors were modeled: 1) child's factors measured by the Activities Scale for Kids, Strengths and Difficulties Questionnaire, and general health measured by SF-36, 2) family characteristics measured by the Impact on Family Scale and 3) environmental barriers measured by the Craig Hospital Inventory of Environmental Factors.

RESULTS

CHQ scores of the study's participants demonstrated significantly lower summary scores from the normative sample for both CHQ Physical and Psychosocial summary scores. On average, children did not change significantly over time for physical summary scores. There was an average increase in psychosocial health that was statistically significant, but small. However, there was evidence of heterogeneity among children. Environmental barriers, behavioral difficulties, family functioning/impact, general health and child physical functioning had negative and significant associations with physical QoL at baseline. Change in physical QoL scores over time was dependent on children's behavioral difficulties, family functioning and environmental barriers. Environmental barriers, behavioral difficulties, family functioning/impact and general health had significant associations with psychosocial scores at baseline, but none served as predictors of change over time.

CONCLUSIONS

Children with physical disabilities differ from the normative group on parent ratings of their physical and psychosocial health. While there was little average change in CHQ scores over 18 months, there is evidence of heterogeneity among children. Factors such as environmental barriers, family functioning/impact, child physical functioning and behavioral difficulties and general health significantly influence QoL scores as measured by the CHQ.

Cerebral palsy in Al-Quseir City, Egypt: prevalence, subtypes, and risk factors

Cerebral palsy (CP) is the most frequent cause of motor handicap. The present door-to-door survey was conducted in Al-Quseir City, Egypt, to investigate the epidemiology of CP. All inhabitants were screened by three neurologists. Medical and neurological examinations were performed for all residents and suspected cases of CP were confirmed by meticulous neurological assessment, brain magnetic resonance imaging, electroencephalography, and testing with the Stanford-Binet Intelligence Scale. Forty-six of 12,788 children aged ≤18 years were found to have CP, yielding a childhood prevalence of 3.6 (95% confidence interval 1.48-2.59) per 1,000 live births. Five adults (aged 19-40 years) among 13,056 inhabitants had CP, giving an adult prevalence of 0.4 (95% confidence interval 0.04-0.72) per 1,000. The risk factors for CP identified in this study were premature birth, low birth weight, neonatal jaundice, neonatal seizures, and recurrent abortion in mothers of children with CP.

At the edge of vulnerability--lived experience of parents of children with cerebral palsy going through surgery

This study explored the experiences of parents of children with cerebral palsy undergoing surgery as they describe them from a lived experience perspective. When children undergo surgical procedures, they have to stay at hospital for a long time, which represents a great challenge for the children as well as their parents. We collected data by using open-ended interviews with 12 parents of 9 children and analyzed these data in accordance with Max van Manen's methodological themes. Based on the parents' stories, the essential theme is: At the edge of vulnerability-being parents at hospital to a child with CP undergoing surgery, which consisted of three subthemes: establishing trust, awareness of a child who cannot speak, and sensing bodily reactions. Parents experienced demanding challenges as they entered the hospital, in a situation that meant both familiarity and unfamiliarity. Judgments about how to care for the child relied on what they normally did. Sitting bedside for hours and days, thoughts about the legitimacy of letting their child go through the suffering surgery were tormenting the parents. They felt vulnerable and very much dependent on health care workers' competence and at the same time doubting them in seeing and taking care of their child's specific needs. It was experienced as an ambivalent situation, and even more so for the parents of a child without speech. The findings indicate that establishing trust implies being met at an existential level and a deeply felt need for health care workers that are really engaged in taking care of their child and their parents.
