Abstract
Importance Cerebral palsy (CP) is the most prevalent neuromotor disability in childhood, but for most cases the etiology remains unexplained. Seasonal variation in the conception of CP may provide clues for their potential etiological risk factors that vary across seasons. Objective To evaluate whether the month or season of conception is associated with CP occurrence. Design, Setting, and Participants This statewide cohort study examined more than 4 million live births that were registered in the California birth records during 2007 to 2015 and were linked to CP diagnostic records (up to year 2021). Statistical analyses were conducted between March 2022 and January 2023. Exposures The month and season of conception were estimated based on the child's date of birth and the length of gestation recorded in the California birth records. Main Outcomes and Measures CP status was ascertained from the diagnostic records obtained from the Department of Developmental Services in California. Poisson regression was used to estimate the relative risk (RR) and 95% CI for CP according to the month or the season of conception, adjusting for maternal- and neighborhood-level factors. Stratified analyses were conducted by child's sex and neighborhood social vulnerability measures, and the mediating role of preterm birth was evaluated. Results Records of 4 468 109 children (51.2% male; maternal age: 28.3% aged 19 to 25 years, 27.5% aged 26 to 30 years; maternal race and ethnicity: 5.6% African American or Black, 13.5% Asian, 49.8% Hispanic or Latinx of any race, and 28.3% non-Hispanic White) and 4697 with CP (55.1% male; maternal age: 28.3% aged 19 to 25 years, 26.0% aged 26 to 30 years; maternal race and ethnicity: 8.3% African American or Black, 8.6% Asian, 54.3% Hispanic or Latinx of any race, and 25.8% non-Hispanic White) were analyzed. Children conceived in winter (January to March) or spring (April to June) were associated with a 9% to 10% increased risk of CP (winter: RR, 1.09 [95% CI, 1.01-1.19]; spring: RR, 1.10 [95% CI, 1.02-1.20]) compared with summer (July to September) conceptions. Analyses for specific months showed similar results with children conceived in January, February, and May being at higher risk of CP. The associations were slightly stronger for mothers who lived in neighborhoods with a high social vulnerability index, but no child sex differences were observed. Only a small portion of the estimated association was mediated through preterm birth. Conclusions and Relevance In this cohort study in California, children conceived in winter and spring had a small increase in CP risk. These findings suggest that seasonally varying environmental factors should be considered in the etiological research of CP.

Incidence of Cerebral Palsy, Risk Factors, and Neuroimaging in Northeast Mexico. Pediatr Neurol 2023; 143:50-58. [PMID: 37001462 DOI: 10.1016/j.pediatrneurol.2023.02.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Revised: 11/17/2022] [Accepted: 02/10/2023] [Indexed: 05/22/2023]
Abstract
BACKGROUND Cerebral palsy (CP) comprises a group of lifelong motor and postural development disorders that can cause static motor encephalopathy. The etiology of CP is attributed to nonprogressive lesions of the central nervous system during fetal or infant brain development. A diagnosis of CP is based on a combination of clinical and neurological signs, typically identified between 12 and 24 months. A medical history, several available standardized tools, including the Neoneuro assessment, and the Hammersmith infant neurological examination (HINE) can be used to predict risk. Magnetic resonance imaging (MRI) can contribute to the diagnosis of CP. The incidence of CP is 2 to 3 per 1000 live births, and in Western industrialized nations, it is 2.0-2.5 per 1000 live births; to our knowledge, no epidemiological studies have reported the incidence of CP in Mexico. AIM To assess the incidence of CP in children aged up to 18 months in northeast Mexico and analyze the risk factors and neuroimaging findings. METHODS This was a multicenter, randomized, prospective, cohort, analytical study of newborn children in three community hospitals and an early intervention and CP center in Nuevo Leon, Mexico, from 2017 to 2021. This study included 3861 newborns randomly selected from a population of 75,951 mothers in the immediate puerperium. According to the Neoneuro tool, high-risk children (n = 432) had abnormal neurological results at birth; they were followed and assessed with the Spanish version of the HINE test by a pediatric neurologist and underwent neuroimaging studies. Neonates with normal results were randomly selected to be in the low-risk group (n= 864). These neonates were followed and assessed with the HINE by a neonatologist. RESULTS The incidence of CP was 4.4 of 1000 up to 18 months old, which was higher than that reported in developed countries. Perinatal risk factors were predominantly recognized in the etiology of CP, such as brain hemorrhage, and prematurity, in addition to congenital anomalies. The most frequent neuroimaging findings were ventricular dilation/cortical atrophy and intraventricular/subependymal hemorrhage and periventricular leukomalacia on MRI. CONCLUSIONS This study is the first on the incidence/prevalence of CP in Mexico, and there are no formal studies in this field in other Latin American countries either. The incidence of CP in northeast Mexico is higher than that reported in developed countries. The follow-up of high-risk young children must be reinforced in the Mexican population, as children with disabilities have high and sequential health-care needs and may usually be lost to follow-up. Neuroimaging of PVL was the more frequent finding by MRI in this population.

Effect of hip CPM on gross motor function and development of the hip joint: a single-center randomized controlled study on spastic cerebral palsy children with hip dysplasia. Front Pediatr 2023; 11:1090919. [PMID: 37228431 PMCID: PMC10203473 DOI: 10.3389/fped.2023.1090919] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Accepted: 04/17/2023] [Indexed: 05/27/2023] Open
Abstract
Objective To investigate the effectiveness of hip continuous passive motion (hCPM) on hip development at skeletal maturity and gross motor function for spastic cerebral palsy children with hip dysplasia. Methods Prospective case-control research of hCPM with goal-directed training versus merely goal-directed training. On the basis of goal-directed training, the hCPM group used the hip joint CPM instrument (the external fixator was connected to the power device to make the hip joint carry out continuous passive movement) for 40-60 min, twice a day, and five times a week, and received continuous training for 8 weeks simultaneously. The control group received only goal-directed training for 8 weeks. Functional outcomes pertaining to the affected hip joints were assessed via gross motor function measure (GMFM), migration percentage (MP), acetabular index (AI), and Harris hip functional score (HHS) at the time of enrollment and the end of the intervention. Results The case-control research included 65 participants (mean age = 46.20 months, SD = 17.09 months; Gross Motor Function Grading System level: III = 41, IV = 24) who were randomly selected to either the hCPM (n = 45) or the control group (n = 20). No differences were found in baseline (acquisition phase) GMFM, MP, AI, or HHS (t = -1.720, P = 0.090; t* = 1.836, P* = 0.071; t# = -1.517, P# = 0.139; t* = -1.310, P* = 0.195; t# = -1.084, P# = 0.097; t = -1.041, P = 0.301). At the 8-week follow-up, GMFM, MP, AI, and HHS significantly improved over baseline in the hCPM group (hCPM group: t = 18.59, 20.172*, 40.291#, 16.820*, 32.900#, 28.081; P < 0.001). Between-group differences at 8-week follow-up times points favored the hCPM group for GMFM (t = -2.637, P = 0.011), MP (t* = 2.615, P* = 0.014; t# = 3.000, P# = 0.006), AI (t* = 2.055, P* = 0.044; t# = 2.223, P# = 0.030), HHS (t = -4.685, P < 0.001) (*: left side; #: right side). Conclusion Spastic cerebral palsy children with hip dysplasia achieved meaningful functional improvement after 8 weeks of goal-directed training with hCPM therapy.

Abstract
Importance Although maternal unintentional injury during pregnancy has shown negative impacts on the mother and fetus, the evidence on its long-term associations with children's neurodevelopment is limited. Objective To examine the association between maternal unintentional injury and cerebral palsy (CP) in offspring. Design, Setting, and Participants This was a population-based, longitudinal, cohort study of all in-hospital live births born between April 1, 2002, and March 31, 2017, in a publicly funded health care system setting of Ontario, Canada. Infants born more than 20 weeks' gestation were included and followed up until March 31, 2018. Excluded from the analysis were stillbirths, infants with missing or invalid records, and births with missing or invalid birth characteristics. Data were analyzed from March 1 to June 30, 2021. Exposures Maternal unintentional injury during pregnancy ascertained based on inpatient or emergency department diagnoses. Main Outcomes and Measures CP diagnosis between birth and the end of follow-up in 2018 with the CP case definition of a single inpatient or 2 or more outpatient diagnoses at least 2 weeks apart between birth and age 16 years. Results Of 2 110 177 children included in this study (mean [SD] gestational age, 38.8 [1.9] weeks; 1 082 520 male [51.3%]), 81 281 (3.9%) were exposed in utero to maternal unintentional injury. During a median (IQR) follow-up time of 8 (4-12) years, 5317 children (0.3%) were diagnosed with CP (292 CP cases [5.5%] were exposed to maternal unintentional injury). The mean incidence rates of CP were 4.36 and 2.93 per 10 000 child-years in the exposed and the unexposed group, respectively. Children exposed to maternal unintentional injury had a modest increase in the risk of CP, compared with those unexposed (hazard ratio [HR], 1.33; 95% CI, 1.18-1.50) after adjusting for maternal sociodemographic and clinical characteristics. Severe injuries that resulted in hospitalization and delivery within 1 week from the injury conferred higher risks of CP (adjusted HR, 2.18; 95% CI, 1.29-3.68 and adjusted HR, 3.40; 95% CI, 1.93-6.00, respectively). Results were robust in multiple bias analyses. Conclusions and Relevance In this Canadian population-based birth cohort study, in utero exposure to maternal unintentional injury was associated with an increased risk of CP, with a higher risk with more severe injuries. These findings fill an important gap in knowledge on the potential role of maternal injury on children's neurodevelopment outcomes. Public health professionals and stakeholders should be aware of these potential long-term consequences on offspring when designing programs and providing recommendations about safety during pregnancy. Early monitoring and developmental assessment of children exposed to maternal injury might be warranted.

Abstract
Cerebral palsy (CP) describes a heterogeneous group of non-progressive neurodevelopmental disorders affecting movement and posture. The etiology and diagnostic biomarkers of CP are a hot topic in clinical research. Recent advances in omics techniques, including genomics, epigenomics, transcriptomics, metabolomics and proteomics, have offered new insights to further understand the pathophysiology of CP and have allowed for identification of diagnostic biomarkers of CP. In present study, we reviewed the latest multi-omics investigations of CP and provided an in-depth summary of current research progress in CP. This review will offer the basis and recommendations for future fundamental research on the pathogenesis of CP, identification of diagnostic biomarkers, and prevention strategies for CP.

Abstract
This study sought to determine data collection approaches in Australian cohort studies and explore the potential impact on reported prenatal alcohol exposure (PAE) prevalence and patterns. Inclusion criteria were that studies related to a general Australian antenatal population where PAE was assessed and reported. Studies were excluded if they were not peer reviewed, examined the prevalence of PAE in pregnancies complicated by alcohol-use disorders, or were published in a language other than English. A systematic search of five electronic databases (PubMed, Embase, CINAHL, Web of Science, and Scopus) was conducted. Risk of bias was assessed using the Effective Public Health Practice Project quality assessment tool. Results were synthesised using MetaXL. Data from 16 separate birth cohorts (n = 78 articles) were included. Included cohorts were either general cohorts that included alcohol as a variable or alcohol-focused cohorts that were designed with a primary focus on PAE. PAE prevalence was estimated as 48% (95% CI: 38 to 57%). When subgroup analysis was performed, estimates of PAE prevalence when self-administered surveys and interviews were used for data collection were 53% (95% CI: 41% to 64%) and 43% (95% CI: 28% to 59%), respectively. Use of trained assessors was an influencing factor of the prevalence estimates when data were collected via interview. Alcohol-focused studies reported higher prevalence of PAE, regardless of method of survey administration. Where interviewer training is not possible, self-administered questionnaires will likely provide the most reliable PAE estimates. No funding sources are relevant to mention. Review was registered with PROSPERO (CRD42020204853).

Abstract
AIM To determine whether infants with intrauterine drug exposure (IUDE) are similarly at risk for cerebral palsy (CP) as other high-risk populations, whether CP classification differs based on IUDE status, and describe the association of CP with specific substances among exposed infants. METHOD This was a retrospective analysis of infants in a high-risk follow-up program (n=5578) between January 2014 and February 2018 with a history of IUDE or who received a CP diagnosis. CP rates were compared using two-sample z-tests. CP classification was assessed using Fisher's exact, Cochran-Armitage, and Wilcoxon rank-sum tests. Models for CP risk were assessed using multivariable logistic regression. RESULTS Among all infants with IUDE (n=1086), 53.8% were male with a mean (SD) birth gestational age of 36.8 (3.6) weeks. Among unexposed infants with CP (n=259), 54.4% were male with a mean (SD) birth gestational age of 29.9 (5.7) weeks. Opioids were the most common exposure (93.7%) of all infants with IUDE. The CP rate in the IUDE (5.2%) and unexposed (5.7%) high-risk populations were not significantly different (p=0.168), nor were there differences in CP typology, topography, or severity between exposed (n=57) and unexposed (n=259) infants (all p>0.05). In patients with IUDE and after controlling for established CP risk factors, the observed odds of CP varied among substances. INTERPRETATION We suggest that IUDE should be considered a 'newborn-detectable risk' in the guidelines for the early detection of CP.

Abstract
OBJECTIVE Neonatal encephalopathy remains a major cause of infant mortality and neurodevelopmental impairment. Infection may exacerbate brain injury and mitigate the effect of therapeutic hypothermia (TH). Additionally, infants with sepsis treated with TH may be at increased risk of adverse effects. This study aimed to review the clinical characteristics and outcomes for infants with sepsis treated with TH. DESIGN AND SETTING Retrospective cohort study of infants treated with TH within Australia and New Zealand. PATIENTS 1522 infants treated with TH, including 38 with culture-positive sepsis from 2014 to 2018. INTERVENTION Anonymised retrospective review of data from Australian and New Zealand Neonatal Network. Infants with culture-positive sepsis within 48 hours were compared with those without sepsis. MAIN OUTCOME MEASURES Key outcomes include in-hospital mortality, intensive care support requirements and length of stay. RESULTS Overall the rate of mortality was similar between the groups (13% vs 13%). Infants with sepsis received a higher rate of mechanical ventilation (89% vs 70%, p=0.01), high-frequency oscillatory ventilation (32% vs 13%, p=0.003) and inhaled nitric oxide for persistent pulmonary hypertension (38% vs 16%, p<0.001). Additionally, the sepsis group had a longer length of stay (20 vs 11 days, p<0.001). CONCLUSION Infants with sepsis treated with TH required significantly more respiratory support and had a longer length of stay. Although this may suggest a more severe illness the rate of mortality was similar. Further research is warranted to review the neurodevelopmental outcomes for these infants.

Abstract
Autism spectrum disorder (ASD) and cerebral palsy (CP) are some of the most common neurodevelopmental diseases. They have multifactorial origin, which means that each case may manifest differently from the others. In patients with ASD, symptoms associated with deficits in social communication and characteristic, repetitive types of behaviors or interests are predominant, while in patients with CP, motor disability is diagnosed with accompanying cognitive impairment of various degrees. In order to minimize their adverse effects, it is necessary to promptly diagnose and incorporate appropriate management, which can significantly improve patient quality of life. One of the therapeutic possibilities is stem cell therapy, already known from other branches of medicine, with high hopes for safe and effective treatment of these diseases. Undoubtedly, in the future we will have to face the challenges that will arise due to the still existing gaps in knowledge and the heterogeneity of this group of patients. The purpose of this systematic review is to summarize briefly the latest achievements and advances in stem cell therapy for ASD and CP.

Yield of clinically reportable genetic variants in unselected cerebral palsy by whole genome sequencing. NPJ Genom Med 2021; 6:74.

Abstract
Cerebral palsy (CP) is the most common cause of childhood physical disability, with incidence between 1/500 and 1/700 births in the developed world. Despite increasing evidence for a major contribution of genetics to CP aetiology, genetic testing is currently not performed systematically. We assessed the diagnostic rate of genome sequencing (GS) in a clinically unselected cohort of 150 singleton CP patients, with CP confirmed at >4 years of age. Clinical grade GS was performed on the proband and variants were filtered, and classified according to American College of Medical Genetics and Genomics–Association for Molecular Pathology (ACMG-AMP) guidelines. Variants classified as pathogenic or likely pathogenic (P/LP) were further assessed for their contribution to CP. In total, 24.7% of individuals carried a P/LP variant(s) causing or increasing risk of CP, with 4.7% resolved by copy number variant analysis and 20% carrying single nucleotide or indel variants. A further 34.7% carried one or more rare, high impact variants of uncertain significance (VUS) in variation intolerant genes. Variants were identified in a heterogeneous group of genes, including genes associated with hereditary spastic paraplegia, clotting and thrombophilic disorders, small vessel disease, and other neurodevelopmental disorders. Approximately 1/2 of individuals were classified as likely to benefit from changed clinical management as a result of genetic findings. In addition, no significant association between genetic findings and clinical factors was detectable in this cohort, suggesting that systematic sequencing of CP will be required to avoid missed diagnoses.

Abstract
Neonatal hypoxic-ischaemic brain damage is a leading cause of child mortality and morbidity, including cerebral palsy, epilepsy, and cognitive disabilities. The majority of neonatal hypoxic-ischaemic cases arise as a result of impaired cerebral perfusion to the foetus attributed to uterine, placental, or umbilical cord compromise prior to or during delivery. Bacterial infection is a factor contributing to the damage and is recorded in more than half of preterm births. Exposure to infection exacerbates neuronal hypoxic-ischaemic damage thus leading to a phenomenon called infection-sensitised hypoxic-ischaemic brain injury. Models of neonatal hypoxia-ischaemia (HI) have been developed in different animals. Both human and animal studies show that the developmental stage and the severity of the HI insult affect the selective regional vulnerability of the brain to damage, as well as the subsequent clinical manifestations. Therapeutic hypothermia (TH) is the only clinically approved treatment for neonatal HI. However, the number of HI infants needed to treat with TH for one to be saved from death or disability at age of 18-22 months, is approximately 6-7, which highlights the need for additional or alternative treatments to replace TH or increase its efficiency. In this review we discuss the mechanisms of HI injury to the immature brain and the new experimental treatments studied for neonatal HI and infection-sensitised neonatal HI.

Abstract
Background and Objectives: This is the first study assessing risk factors for cerebral palsy (CP) among children born in Moldova. The aim of this study was to identify and describe risk factors for cerebral palsy (CP) among children born in Moldova, which is one of the low-middle income countries in Europe. Materials and Methods: We identified 351 children with CP born during 2009 and 2010 in Moldova. Detailed information on 417 children without CP served as a reference group. Logistic regression analyses were applied to the calculate crude and adjusted odds ratios (OR) for CP with 95% confidence intervals (CI) in addition to attributable fraction (AF). Results: Among children with CP (40.5% girls), 26% had spastic unilateral, 54% bilateral, 13% dyskinetic, 5% ataxic and 2% unclassified CP. Significant risk factors for CP included maternal alcohol consumption during pregnancy (OR 1.7, p = 0.002), maternal hypertension (OR 2.0, p < 0.001), children born to mothers from the rural areas (OR 1.6, p < 0.001), maternal age ≥35 years (OR 0.6, p = 0.018), maternal epilepsy (OR 4.3, p < 0.001), breech delivery (OR 3.1, p = 0.001), home births (OR 6.3, p = 0.001), umbilical cord around neck (OR 2.2, p < 0.001), AVD (OR 3.1, p < 0.001), male gender (OR 1.3, p < 0.001), SGA (OR 1.3, p = 0.027), multiple gestations (OR 1.7, p < 0.001) and hyperbilirubinemia (OR 4.5, p < 0.001). Multivariable analyses showed that the AF of CP was 64% for rural residence (OR 2.8, p = 0.002), 87% for home birth (7.6, p = 0.005), 79% for pre-labor rupture of membrane (OR 4.9, p = 0.001), 66% for breech delivery (OR 2.9, p = 0.002) and 81% for hyperbilirubinemia (OR 5.4, p < 0.001). Conclusions: A combination of factors related to the mother, the delivery and the child were risk factors for CP in Moldova, many of them possibly avoidable. Improved pregnancy and maternity care would potentially reduce the risk of CP. A national CP registry in Moldova is suggested as an opportunity to follow up on these findings.

Abstract
BACKGROUND The birth of a child affected by a threatened abortion (TAB) in utero is associated with autism spectrum disorder; association with other neurological disorders is unknown. METHODS This nationwide registry-based cohort study included singletons live-born in Denmark (1979-2010), followed through 2016. The outcomes were epilepsy, cerebral palsy (CP) and attention-deficit/hyperactivity disorder (ADHD). We used Cox regression to compute hazard ratios (HRs), adjusted for birth year, birth order, parental age, morbidity, medication use and maternal socio-economic factors. To remove time-invariant family-shared confounding, we applied sibling analyses. RESULTS The study population included 1 864 221 singletons live-born in 1979-2010. Among the TAB-affected children (N = 59 134) vs TAB-unaffected children, at the end of follow-up, the cumulative incidence was 2.2% vs 1.6% for epilepsy, 0.4% vs 0.2% for CP and 5.5% vs 4.2% for ADHD (for children born in 1995-2010). The adjusted HRs were 1.25 [95% confidence interval (CI) 1.16-1.34] for epilepsy, 1.42 (95% CI 1.20-1.68) for CP and 1.21 (95% CI 1.14-1.29) for ADHD. In the sibling design, the adjusted HRs were unity for epilepsy (full siblings: 0.96, 95% CI 0.82-1.12; maternal: 1.04, 95% CI 0.90-1.20; paternal: 1.08, 95% CI 0.93-1.25) and ADHD (full: 1.08, 95% CI 0.92-1.27; maternal: 1.04, 95% CI 0.90-1.20; paternal: 1.08, 95% CI 0.93-1.25). For CP, HRs shifted away from unity among sibling pairs (full: 2.92, 95% CI 1.33-6.39; maternal: 2.03, 95% CI 1.15-3.57; paternal: 3.28, 95% CI 1.36-7.91). CONCLUSIONS The birth of a child affected by TAB in utero was associated with a greater risk of CP, but not epilepsy or ADHD.

Abstract
BACKGROUND Neuroradiological studies have greatly improved the knowledge and diagnoses of cerebral palsy with its underlying pathology, types and accompanying changes in brain morphology. However, there is no published study on cerebral palsy neuroimaging patterns in Ethiopia. METHODS Retrospective chart and neuroimaging reviews were conducted among pediatric patients, who attended Ayder Comprehensive Specialized Hospital between January 2016 and August 2019, fulfilling the study criteria. The magnetic resonance images and computed tomography scans reviewed by a neuroradiologist and/or pediatric neurologist were included. Data was collected using a structured checklist and analyzed using SPSS statistical software version 22. Results were represented using tables, graphs and images. RESULTS The median age at neuroimaging was 2 years. There were more males (54.5%) than females (45.5%) with a male: female ratio of 1.2:1. Majority of the patients had magnetic resonance (81.8%) as opposed to computed tomography scans (18.2%). Most of the patients (69.7%) had been born at term with spastic quadriplegia (33.3%) found to be the leading type of cerebral palsy. 30.3% of the patients had normal neuroimaging studies whereas 69.7% had neuroimaging abnormalities. Anomalies included pathologies of the white matter (18.2%), basal ganglia (15.2%), cortex and lobes (27.3%), corpus callosum (6.1%), lateral ventricles (12.1%), cysts (18.2%) and cerebellum (3%), respectively. Other findings were seen in 45.5% of the patients. CONCLUSION Severe forms of cerebral palsy (spastic quadriplegia) were most common with majorly cortical and subcortical brain involvement.

Abstract
AIM To quantify and analyse the prevalence and clinical features of cerebral palsy (CP) in Denmark for birth years 2008-2013 and compare results with previous periods. METHOD A nationwide register-based study covering all children with a confirmed diagnosis of CP born in Denmark. Information about CP subtype, aetiology and severity was collected from the Cerebral Palsy Follow-up Program and supplemented from medical files. Data from the Danish Medical Birth Register was included, and the results were compared to previous data from the Danish National Cerebral Palsy Register. Prevalence per 1000 live births and proportions were analysed using the Cochran-Armitage test for trend. RESULTS The period covered 368,618 live births and 636 children with CP, making the overall prevalence for the period 1.73 per 1000 live births. This was significantly lower than the prevalence of 1.99 for the previous period 1999-2007 (p = 0.004). The decline in prevalence between the two periods was mainly due to a decrease in children with bilateral spastic and dyskinetic CP born after 37 gestational weeks. The decline in prevalence was accompanied by a smaller proportion of children with associated impairment. CONCLUSION We found a decrease in prevalence and severity in CP among Danish children. The decline was most pronounced in children born after 37 gestational weeks with severe subtypes of CP. National guidelines that recommend induction of labour before the completion of week 42 and therapeutic hypothermia for term neonates with hypoxic-ischaemic encephalopathy, may have contributed to the decline.

Abstract
Cerebral Palsy (CP) is one of the foremost causes of childhood motor disability and disrupts the individual's development and ability to function. Several factors contribute to the development of CP such as preterm delivery, low birth weight, infection/inflammation, and additional pregnancy complications, both in preterm and term infants. As there is no specific treatment for CP, rehabilitation is the current option for the management of patients. The serious nature of this condition creates deficits that last a lifetime. We collected studies that were published in the past 10 years, using PubMed as our main database. We chose studies that were relevant to CP and stem cell therapy. We mainly focused on various types of stem cells that can be used in treatment, mechanism of action (MOA) of stem cells, routes, dosage, and adverse effects, their efficacy, and safety in CP patients. Of all the 38 studies we reviewed, we found that five articles discussed the utilization of human umbilical cord blood [hUCB], four articles discussed autologous bone marrow stem cells, and one discussed allogeneic umbilical cord blood usage. One article discussed neural stem-like cells (NSLCs) derived from bone marrow and the remaining 27 articles were about CP and its treatment. We reviewed detailed information about the possible stem cell therapies and their benefits in patients with CP. We found that immune modulation is the major mechanism of action of stem cells, and among all the types of stem cells. Autologous umbilical cord mesenchymal stem cells appear to be safe and most effective in treatment compared to other stem cell treatments. Among all symptoms, motor symptoms are best corrected by stem cell therapy. Still, it did not show any marked improvement in treating other symptoms like speech defects, sensory or cognitive defects, or visual impairment.

Abstract
Cerebral palsy (CP) is the most common neuro-motor disability in young children. Disruptions of maternal hormone function during pregnancy have been linked to CP risk. We investigated whether prenatal exposure to pesticide compounds with endocrine-disrupting action affect CP risk. We conducted a case-control study of 3905 CP cases and 39,377 controls born between 1998 and 2010 in California to mothers who lived in proximity (within 2 km) to any agricultural pesticide application recorded in the California Pesticide Use Reporting (PUR) system. We focused on 23 pesticides considered endocrine disruptors that are frequently used, and we found that exposure to any of the 23 pesticides in the first trimester was associated with elevated CP risks in female offspring (OR = 1.19; 95% CI: 1.05-1.35) but not males (OR = 0.99; 95% CI: 0.89-1.09) compared to the unexposed offspring. Positive associations were estimated for 15 pesticides suspected to affect the estrogen and 7 pesticides suspected to affect the thyroid hormone system. Our study suggests that first trimester exposure to pesticides that are suspected endocrine disruptors are associated with CP risk in female offspring. Pesticide exposures in early pregnancy may have sex-specific influences on the neuro-motor development of the fetus by interfering with endocrine systems.

Congenital Malformations in Children With Cerebral Palsy: Is Prematurity Protective? Pediatr Neurol 2020; 108:70-76. [PMID: 32386793 DOI: 10.1016/j.pediatrneurol.2020.02.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2019] [Revised: 01/27/2020] [Accepted: 02/01/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND Congenital malformations are more common in children who are born prematurely, and prematurity is the leading risk factor for cerebral palsy. The primary objective of this study was to describe the profile of congenital malformations in a Canadian cohort of children with cerebral palsy. The secondary objectives were to compare the profiles of children with cerebral palsy with and without a congenital malformation and explore the possible role of prematurity. METHODS This retrospective cohort study utilized data from the Canadian Cerebral Palsy Registry, a population based registry of children with a confirmed diagnosis of cerebral palsy. Differences between groups were compared using Pearson's chi-square and Student t test as appropriate. Odds ratios and 95% confidence intervals were calculated RESULTS: Congenital malformations were present in 23% participants. In term-born children, brain malformations were the most common, whereas heart and gastrointestinal malformations were more common in children born prematurely. Children with a malformation had higher odds of being born at term (odds ratio 1.57, 95% confidence interval 1.20 to 2.04); having hypotonic, ataxic, or dyskinetic cerebral palsy (odds ratio 1.92, 95% confidence interval 1.35 to 2.72; being nonambulatory (odds ratio 1.70, 95% confidence interval 1.29 to 2.25); and having cerebral palsy-associated comorbidities. CONCLUSIONS One in four children with cerebral palsy have an associated congenital malformation. Their profile of term birth, higher Apgar scores, and lower frequency of perinatal seizures suggests a distinct causal pathway.

Abstract
Cerebral palsy (CP), defined as a group of nonprogressive disorders of movement and posture, is the most common cause of severe neurodisability in children. The prevalence of CP is the same across the globe, affecting approximately 17 million people worldwide. Cerebral Palsy is an umbrella term used to describe the disease due to its inherent heterogeneity. For instance, CP has multiple (1) causes; (2) clinical types; (3) patterns of neuropathology on brain imaging and (4) it's associated with several developmental pathologies such as intellectual disability, autism, epilepsy, and visual impairment. Understanding its physiopathology is crucial to developing protective strategies. Despite its importance, there is still insufficient progress in the areas of CP prediction, early diagnosis, treatment, and prevention. Herein we describe the current risk factors and biomarkers used for the diagnosis and prediction of CP. With the advancement in biomarker discovery, we predict that our understanding of the etiopathophysiology of CP will also increase, lending to more opportunities for developing novel treatments and prognosis.

Abstract
Objective: A risk prediction model of cerebral palsy (CP) was established by a decision tree model to predict the individual risk of CP.Methods: A hospital-based case-control study was conducted with 109 cases of CP and 327 controls without CP. The cases and the controls were obtained from Hunan Children's Hospital. A questionnaire was administered to collect the variables relevant to CP by face to face interviews. Chi-square test was used to identify the factors associated with CP, and a decision tree model was used to construct the prediction model.Results: Univariate analysis showed that there were significant differences between cases group and controls group on maternal age, weight gain during pregnancy, medical treatment during pregnancy, preterm birth, low birth weight and birth asphyxia (all p-values <.05). Three factors, including preterm birth, birth asphyxia, and maternal age >35 years old, entered the decision tree model. The area under the receiver operating characteristic curve (AUC) was 0.722 (95%CI: 0.659-0.784, p < .001).Conclusion: The decision tree prediction model can be used for predicting the individual risk of CP. Further large-scale, population-based cerebral palsy studies are needed to improve the model.

Abstract
An extensive review of the literature on the diagnostic and clinical accuracy of Kurjak's antenatal neurodevelopmental test (KANET) and the summarized results of the multi-center study involving 10 centers revealed that four-dimensional ultrasonography (4D US) has become a powerful tool and KANET a valuable test that empowers the clinicians worldwide to evaluate the fetal behavior in a systematic way and contribute to the detection of fetuses that might be at high risk for neurological impairments and in particular cerebral palsy (CP). After 10 years of clinical use, many published papers and multi-center studies, hundreds of trained physicians and numerous tests performed all over the world, KANET has proven its value and has been showing encouraging results so far. The aim of this paper is to show the results from the studies done so far and to reveal the clinical value of the KANET. We expect that data from the larger ongoing collaborative study, the short- and long-term postnatal follow-up will continue to improve our knowledge. Ultimately, we all strive to prevent the CP disorders, autism spectrum disorder (ASD) and other neurological impairments and we are convinced that KANET might be helpful in the realization of this important aim.

Abstract
Cerebral palsy (CP) is a group of non-progressive motor impairment syndromes that are secondary to brain injury in the early stages of brain development. Numerous etiologies and risk factors of CP have been reported, and genetic contributions have recently been identified. Autophagy has an important role in brain development and pathological process, and autophagy-related gene 7 (ATG7) is essential for autophagosome biogenesis. The purpose of this study was to investigate the genetic association between ATG7 gene single nucleotide polymorphisms (SNPs) and CP in Han Chinese children. Six SNPs (rs346078, rs1470612, rs11706903, rs2606750, rs2594972, and rs4684787) were genotyped in 715 CP patients and 658 healthy controls using the MassArray platform. Plasma ATG7 protein was determined in 73 CP patients and 79 healthy controls. The differences in the allele and genotype frequencies of the rs1470612 and rs2594972 SNPs were determined between the CP patients and controls (p allele = 0.02 and 0.0004, p genotype = 0.044 and 0.0012, respectively). Subgroup analysis revealed a more significant association of rs1470612 (p allele = 0.004, p genotype = 0.0036) and rs2594972 (p allele = 0.0004, p genotype < 0.0001) with male CP, and more significant differences in allele and genotype frequencies were also noticed between CP patients with spastic diplegia and controls for rs1470612 (p allele = 0.0024, p genotype = 0.008) and rs2594972 (p allele < 0.0001, p genotype = 0.006). The plasma ATG7 level was higher in CP patients compared to the controls (10.58 ± 0.85 vs. 8.18 ± 0.64 pg/mL, p = 0.024). The luciferase reporter gene assay showed that the T allele of rs2594972 SNP could significantly increase transcriptional activity of the ATG7 promoter compared to the C allele (p = 0.009). These findings suggest that an association exists between genetic variants of ATG7 and susceptibility to CP, which provides novel evidence for the role of ATG7 in CP and contributes to our understanding of the molecular mechanisms of this neurodevelopmental disorder.

Abstract
Objective When delivery of a breech fetus is required at a preterm gestational age, Cesarean delivery is often recommended. We performed a prospective patient series to assess the success rate and safety of performing external cephalic version (ECV) procedures on preterm fetuses as an alternative to Cesarean delivery. Study Design We performed a prospective clinical series of patients who required delivery with a malpresenting fetus at a preterm gestational age. Results ECV procedures were successful in singletons 50% of the time. No significant complications or cases of fetal mortality were documented. Conclusion ECV at preterm gestational ages may be an appropriate approach to management in patients requiring delivery. Larger series are needed to further document success rates and risks of the procedure.

Abstract
Co-existing infection/inflammation and birth asphyxia potentiate the risk of developing neonatal encephalopathy (NE) and adverse outcome. In a newborn piglet model we assessed the effect of E. coli lipopolysaccharide (LPS) infusion started 4 h prior to and continued for 48 h after hypoxia on brain cell death and systemic haematological changes compared to LPS and hypoxia alone. LPS sensitized hypoxia resulted in an increase in mortality and in brain cell death (TUNEL positive cells) throughout the whole brain, and in the internal capsule, periventricular white matter and sensorimotor cortex. LPS alone did not increase brain cell death at 48 h, despite evidence of neuroinflammation, including the greatest increases in microglial proliferation, reactive astrocytosis and cleavage of caspase-3. LPS exposure caused splenic hypertrophy and platelet count suppression. The combination of LPS and hypoxia resulted in the highest and most sustained systemic white cell count increase. These findings highlight the significant contribution of acute inflammation sensitization prior to an asphyxial insult on NE illness severity.

Abstract
Purpose: An observational study using routinely-collected health care data to describe the extent to which children and young people (CYP) with cerebral palsy (CP) can be identified and the prevalence of CP can be estimated. Patients and methods: Routinely-collected anonymized data, for CYP (aged 0–25 years old between 1 January 2004 and 31 December 2014) were analyzed in two linked datasets, from England and Wales respectively. Datasets included National Health Service; General Practitioner (GP), inpatients, outpatients, and national mortality records. CP was identified using ICD-10 codes G80.0–G83.3 and equivalent Read v2 codes. Ascertainment rates of CP were identified for each data source and compared between countries. Frequency and consistency of coding were investigated, and prevalence of CP estimated. Results: A total of 7,113 and 5,218 CYP with CP were identified in the English and Welsh datasets respectively. Whilst the majority of CYP with CP would be expected to attend their GP, 65.3% (4,646/7,113) of English and 65.1% (3,396/5,218) of Welsh cases were ascertained from GP datasets. Further cases were identified solely in inpatient datasets (2,410 in England, 1,813 in Wales). Few cases were coded for CP within outpatient datasets. Four character codes that specified CP type were rarely used; one in five health care records were coded both with G80 codes (explicitly CP) and with G81–83 codes (other paralytic syndromes) or equivalent Read codes. Estimated period prevalence of CYP with CP was 2.5–3.4 per 1,000 in England and 2.4–3.2 per 1,000 in Wales. Conclusion: In England and Wales, coding of CP in routine data is infrequent, inconsistent, non-specific, and difficult to isolate from conditions with similar physical signs. Yet the prevalence estimates of CP were similar to those reported elsewhere. To optimize case recognition we recommend improved coding quality and the use of both primary and secondary care datasets as a minimum.

Abstract
OBJECTIVE To compare neurodevelopmental outcomes of preterm infants at 18-21 months corrected age (CA) whose mothers smoked during pregnancy to those whose mothers did not smoke. STUDY DESIGN Preterm infants born at <29 weeks of gestation and evaluated at 18-21 months CA were included. Primary outcome was a composite outcome of death or neurodevelopmental impairment (NDI). RESULTS Of a total of 2760 infants, 699 met exclusion criteria. Of the remaining 2061 infants, 280 (13.6%) were exposed to maternal smoking and 1781 (86.4%) were not. The odds of the composite outcome of death or NDI (aOR 1.40; 95% CI: 1.03-1.91), NDI alone (aOR 1.43; 95% CI: 1.01-2.03), and Bayley-III motor score <85 (aOR 1.91; 95% CI: 1.31-2.81) were higher in exposed infants. CONCLUSIONS Exposure to maternal smoking was associated with adverse composite outcome of death or NDI, NDI alone and lower motor scores at 18-21 months CA.

Abstract
Spastic cerebral palsy (CP), despite the name, is not consistently identifiable by specific brain lesions. CP animal models focus on risk factors for development of CP, yet few reproduce the diagnostic symptoms. Animal models of CP must advance beyond risk factors to etiologies, including both the brain and spinal cord.

Abstract
AIM Several studies have examined the links between maternal obesity and the risk of cerebral palsy (CP) in children, with inconsistent results. The aim of our study was to investigate whether maternal obesity is associated with increased risk of CP in offspring by using meta-analysis. METHOD PubMed and Web of Science were searched until August 2017. Observational studies relevant to the maternal obesity and risk of CP in children were extracted and compiled. Meta-analyses were performed for different obesity levels and pooled odds ratios (ORs) and 95% confidence intervals (CIs) were reported. RESULTS A total of five cohort studies involving 12 324 cases and 7 919 288 participants were included in our meta-analysis. The pooled crude and adjusted ORs (95% CIs) were 1.65 (1.38-1.98) and 1.51 (1.24-1.84) respectively. Additionally, the pooled OR (95% CI) for CP in offspring in relation to maternal obesity class I (body mass index [BMI] 30.0-34.9), class II (BMI 35.0-39.9), and class III (BMI≥40.0) compared with normal weight during prepregnancy or pregnancy was 1.31 (1.15-1.50), 1.65 (1.34-2.02), and 2.37 (1.91-2.94) respectively. INTERPRETATION This meta-analysis demonstrated that increasing grades of maternal obesity are associated with a higher risk of CP in offspring. WHAT THIS PAPER ADDS Meta-analysis demonstrates a significant positive association between maternal obesity and the risk of cerebral palsy (CP) in children. Subgroup analysis indicates that higher grades of maternal obesity are associated with increasing risk of CP.

Abstract
OBJECTIVES To synthetize the available evidence regarding the incidence and risk factors of preterm premature rupture of membranes (PPROM). To describe the evolution of pregnancy, neonatal outcomes and the prognosis of infants born in a context of PPROM, according to the existence of an associated intrauterine infection and to the latency duration. METHOD Consultation of the Medline database, from 1980 to February 2018. RESULTS PPROM before 37 and before 34 weeks' gestation occur in 2-3% and <1% of pregnancies, respectively (LE2). Although many risk factors are identified, few are modifiable, and the vast majority of patients have no risk factors (LE2). Consequently, individual prediction of the risk of PPROM and primary prevention measures have not been shown to be effective and are not recommended in clinical practice (Grade B). Most women give birth within the week following PPROM (LE2). The main complications of PPROM are prematurity, intrauterine infection and obstetric and maternal complications (LE2). Latency duration and the frequency of complications decrease with increasing gestational age at PPROM (LE2). Neonatal prognosis is largely conditioned by gestational age at birth, with no apparent over-risk of poor outcomes linked to PPROM compared to other causes of preterm birth (LE2). In contrast, intrauterine infection is associated with an increased risk of in utero fetal death (LE3), necrotizing enterocolitis (LE1) and early-onset sepsis (LE2). The association of intrauterine infection with neurological morbidity remains controversial. Prolongation of latency, from gestational age at PPROM, is beneficial for the child (LE2). CONCLUSION PPROM is a major cause of prematurity and short- and long-term mortality and morbidity. Antenatal care is an important issue for obstetric and pediatric teams, aiming to reduce complications and adverse consequences for both mother and child.

Abstract
Cerebral palsy (CP) is the most prevalent, severe and costly motor disability of childhood. Consequently, CP is a public health priority for prevention, but its aetiology has proved complex. In this Review, we summarize the evidence for a decline in the birth prevalence of CP in some high-income nations, describe the epidemiological evidence for risk factors, such as preterm delivery and fetal growth restriction, genetics, pregnancy infection and other exposures, and discuss the success achieved so far in prevention through the use of magnesium sulfate in preterm labour and therapeutic hypothermia for birth-asphyxiated infants. We also consider the complexities of disentangling prenatal and perinatal influences, and of establishing subtypes of the disorder, with a view to accelerating the translation of evidence into the development of strategies for the prevention of CP.

Abstract
Cerebral palsy (CP) is the most common motor disability of childhood. It is characterised by permanent, non-progressive but not unchanging problems with movement, posture and motor function, with a highly heterogeneous clinical spectrum and frequent neurodevelopmental comorbidities. The aetiology of CP is poorly understood, despite recent reports of a genetic contribution in some cases. Here we demonstrate transcriptional dysregulation of trophic signalling pathways in patient-derived cell lines from an unselected cohort of 182 CP-affected individuals using both differential expression analysis and weighted gene co-expression network analysis (WGCNA). We also show that genes differentially expressed in CP, as well as network modules significantly correlated with CP status, are enriched for genes associated with ASD. Combining transcriptome and whole exome sequencing (WES) data for this CP cohort likely resolves an additional 5% of cases separated to the 14% we have previously reported as resolved by WES. Collectively, these results support a convergent molecular abnormality in CP and ASD.

Abstract
The authors hypothesized that the risk of cerebral palsy at 2 years in children born extremely preterm to overweight and obese women is increased relative to the risk among children born to neither overweight nor obese women. In a multicenter prospective cohort study, the authors created multinomial logistic regression models of the risk of diparetic, quadriparetic, and hemiparetic cerebral palsy that included the prepregnancy body mass index of mothers of 1014 children born extremely preterm, cerebral palsy diagnoses of children at 2 years, as well as information about potential confounders. Overweight and obese women were not at increased risk of giving birth to a child who had cerebral palsy. The risk ratios associated with overweight varied between 1.1 for quadriparesis (95% CI = 0.5, 2.1) to 2.0 for hemiparesis (95% CI = 0.4, 9.8). The risk ratios associated with obesity varied between 0.7 for diparesis (95% CI = 0.2, 2.5) to 2.5 for hemiparesis (95% CI = 0.4, 13).

Abstract
A diagnosis of fetal growth restriction and subsequent preterm birth is associated with increased risks of adverse perinatal and neurodevelopmental outcomes and potentially long-lasting effects to adulthood. Most such cases are associated with placental insufficiency and the fetal response to chronic intrauterine hypoxemia and nutrient deprivation leads to substantial physiological and metabolic adaptations. The management of such pregnancies, especially with respect to perinatal interventions and birth mode, remains an unresolved dilemma. The benefits from standard interventions for threatened preterm birth may not be necessarily translated to pregnancies with small-for-gestational-age fetuses. Clinical trials or retrospective studies on outcomes following administration of antenatal glucocorticoids and magnesium sulfate for neuroprotection when preterm birth is imminent either have yielded conflicting results for small-for-gestational-age fetuses, or did not include this subgroup of patients. Experimental models highlight potential harmful effects of administration of antenatal glucocorticoids and magnesium sulfate in the pregnancies with fetal small for gestational age although clinical data do not substantiate these concerns. In addition, heterogeneity in definitions of fetal small for gestational age, variations in the inclusion criteria, and the glucocorticoid regime contribute to inconsistent results. In this review, we discuss the physiologic adaptions of the small-for-gestational-age fetus to its abnormal in utero environment in relation to antenatal glucocorticoids; the impact of antenatal glucocorticoids and intrapartum magnesium sulfate in pregnancies with fetal small for gestational age; the current literature on birth mode for pregnancies with fetal small for gestational age; and the knowledge gaps in the existing literature.

Abstract
INTRODUCTION Though the human fetus is exposed to placentally derived human chorionic gonadotropin (hCG) throughout gestation, the role of hCG on the fetal brain is unknown. Review of the available literature appears to indicate that groups of women with higher mean levels of hCG during pregnancy tend to have offspring with lower cerebral palsy (CP) risk. Given that newborn cerebral injury often precedes the development of CP, we aimed to determine whether hCG may protect against the neurodegenerative effects of neonatal brain injury. METHODS We utilized the Rice-Vannucci model of neonatal cerebral hypoxia-ischemia (HI) in postnatal day 7 mice to examine whether intraperitoneal administration of hCG 15-18 h prior, 1 h after or immediately following HI decrease brain tissue loss 7 days after injury. We next studied whether hCG has pro-survival and trophic properties in neurons by exposing immature cortical and hippocampal neurons to hCG in vitro and examining neurite sprouting and neuronal survival prior and after glutamate receptor-mediated excitotoxic injury. RESULTS We found that intraperitoneal injection of hCG 15 h prior to HI, but not at or 1 h after HI induction, resulted in a significant decrease in hippocampal and striatal tissue loss 7 days following brain injury. Furthermore, hCG reduced N-methyl-d-aspartate (NMDA)-mediated neuronal excitotoxicity in vitro when neurons were continuously exposed to this hormone for 10 days or when given at the time and following neuronal injury. In addition, continuous in vitro administration of hCG for 6-9 days increased neurite sprouting and basal neuronal survival as assessed by at least a 1-fold increase in MAP2 immunoreactivity and a 2.5-fold increase in NeuN + immunoreactivity. CONCLUSION Our findings suggest that hCG can decrease HI-associated immature neural degeneration. The mechanism of action for this neuroprotective effect may partly involve inhibition of NMDA-dependent excitotoxic injury. This study supports the hypothesis that hCG during pregnancy has the potential for protecting the developing brain against HI, an important CP risk factor.

Abstract
BACKGROUND Cerebral palsy (CP) is a neurodevelopmental disorder resulting from an injury to the developing brain. It is the most common form of childhood disability with prevalence rates of between 1.5 and 3.8 per 1000 births reported worldwide. The primary impairments associated with CP include reduced muscle strength and reduced cardiorespiratory fitness, resulting in difficulties performing activities such as dressing, walking and negotiating stairs.Exercise is defined as a planned, structured and repetitive activity that aims to improve fitness, and it is a commonly used intervention for people with CP. Aerobic and resistance training may improve activity (i.e. the ability to execute a task) and participation (i.e. involvement in a life situation) through their impact on the primary impairments of CP. However, to date, there has been no comprehensive review of exercise interventions for people with CP. OBJECTIVES To assess the effects of exercise interventions in people with CP, primarily in terms of activity, participation and quality of life. Secondary outcomes assessed body functions and body structures. Comparators of interest were no treatment, usual care or an alternative type of exercise intervention. SEARCH METHODS In June 2016 we searched CENTRAL, MEDLINE, Embase, nine other databases and four trials registers. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs of children, adolescents and adults with CP. We included studies of aerobic exercise, resistance training, and 'mixed training' (a combination of at least two of aerobic exercise, resistance training and anaerobic training). DATA COLLECTION AND ANALYSIS Two review authors independently screened titles, abstracts and potentially relevant full-text reports for eligibility; extracted all relevant data and conducted 'Risk of bias' and GRADE assessments. MAIN RESULTS We included 29 trials (926 participants); 27 included children and adolescents up to the age of 19 years, three included adolescents and young adults (10 to 22 years), and one included adults over 20 years. Males constituted 53% of the sample. Five trials were conducted in the USA; four in Australia; two in Egypt, Korea, Saudi Arabia, Taiwan, the Netherlands, and the UK; three in Greece; and one apiece in India, Italy, Norway, and South Africa.Twenty-six trials included people with spastic CP only; three trials included children and adolescents with spastic and other types of CP. Twenty-one trials included people who were able to walk with or without assistive devices, four trials also included people who used wheeled mobility devices in most settings, and one trial included people who used wheeled mobility devices only. Three trials did not report the functional ability of participants. Only two trials reported participants' manual ability. Eight studies compared aerobic exercise to usual care, while 15 compared resistance training and 4 compared mixed training to usual care or no treatment. Two trials compared aerobic exercise to resistance training. We judged all trials to be at high risk of bias overall.We found low-quality evidence that aerobic exercise improves gross motor function in the short term (standardised mean difference (SMD) 0.53, 95% confidence interval (CI) 0.02 to 1.04, N = 65, 3 studies) and intermediate term (mean difference (MD) 12.96%, 95% CI 0.52% to 25.40%, N = 12, 1 study). Aerobic exercise does not improve gait speed in the short term (MD 0.09 m/s, 95% CI -0.11 m/s to 0.28 m/s, N = 82, 4 studies, very low-quality evidence) or intermediate term (MD -0.17 m/s, 95% CI -0.59 m/s to 0.24 m/s, N = 12, 1 study, low-quality evidence). No trial assessed participation or quality of life following aerobic exercise.We found low-quality evidence that resistance training does not improve gross motor function (SMD 0.12, 95% CI -0.19 to 0.43, N = 164, 7 studies), gait speed (MD 0.03 m/s, 95% CI -0.02 m/s to 0.07 m/s, N = 185, 8 studies), participation (SMD 0.34, 95% CI -0.01 to 0.70, N = 127, 2 studies) or parent-reported quality of life (MD 12.70, 95% CI -5.63 to 31.03, n = 12, 1 study) in the short term. There is also low-quality evidence that resistance training does not improve gait speed (MD -0.03 m/s, 95% CI -0.17 m/s to 0.11 m/s, N = 84, 3 studies), gross motor function (SMD 0.13, 95% CI -0.30 to 0.55, N = 85, 3 studies) or participation (MD 0.37, 95% CI -6.61 to 7.35, N = 36, 1 study) in the intermediate term.We found low-quality evidence that mixed training does not improve gross motor function (SMD 0.02, 95% CI -0.29 to 0.33, N = 163, 4 studies) or gait speed (MD 0.10 m/s, -0.07 m/s to 0.27 m/s, N = 58, 1 study) but does improve participation (MD 0.40, 95% CI 0.13 to 0.67, N = 65, 1 study) in the short-term.There is no difference between resistance training and aerobic exercise in terms of the effect on gross motor function in the short term (SMD 0.02, 95% CI -0.50 to 0.55, N = 56, 2 studies, low-quality evidence).Thirteen trials did not report adverse events, seven reported no adverse events, and nine reported non-serious adverse events. AUTHORS' CONCLUSIONS The quality of evidence for all conclusions is low to very low. As included trials have small sample sizes, heterogeneity may be underestimated, resulting in considerable uncertainty relating to effect estimates. For children with CP, there is evidence that aerobic exercise may result in a small improvement in gross motor function, though it does not improve gait speed. There is evidence that resistance training does not improve gait speed, gross motor function, participation or quality of life among children with CP.Based on the evidence available, exercise appears to be safe for people with CP; only 55% of trials, however, reported adverse events or stated that they monitored adverse events. There is a need for large, high-quality, well-reported RCTs that assess the effectiveness of exercise in terms of activity and participation, before drawing any firm conclusions on the effectiveness of exercise for people with CP. Research is also required to determine if current exercise guidelines for the general population are effective and feasible for people with CP.

Abstract
Aim and Objective: Cerebral palsy (CP) is the most common motor disability in childhood. This study aimed to describe clinical spectrum, comorbidities, and risk factors associated with CP children. Materials and Methods: This hospital-based observational study was conducted in tertiary level hospital in Jaipur including 180 CP children aged 1–12 years, attending the Paediatric Neurology Outdoor and Child Development Centre. A detailed history of antenatal, natal, and postnatal events taken and thorough examination was performed to stratify children in proper topographical and physiological classification. Results: Mothers of 47.7% CP children were primigravida and 17.7% mothers had anemia during pregnancy. Among natal factors, asphyxia contributed to maximum cases (52.2%). Seizure in postnatal life was the second most common risk factor for CP after asphyxia. Spastic CP (84.4%) was the most common physiological type, and quadriplegia (56.6%) was the most common topographical type observed in this study. Intellectual disability (47.7%) followed by epilepsy (41.6%) was the most common comorbidity. Conclusion: Even with the advancement of health-care system, asphyxia is the most common risk factor, and spastic quadriplegia is the most common type of CP. There is still a need of improving the health facilities to overcome this costly and common neuromotor disability. Widespread knowledge of common risk factors that can predispose to CP can prevent the CP development to some extent and knowledge of clinical spectrum, and comorbidities can improve their targeted treatment which can improve their growth and social participation.

Abstract
AIM The overall aim was to investigate the feasibility and utility of linking a cerebral palsy (CP) register to an administrative data set for health services research purposes. We sought to compare CP hospital admissions to general childhood population admissions, and identify factors associated with type and frequency of admissions in a CP cohort. METHOD The CP register for Victoria, Australia was linked to the state's hospital admissions database. Data pertaining to the admissions of a CP cohort (n=1748) that took place between 2007 and 2014 were extracted. Population data were also obtained. RESULTS Overall, 80% of the CP cohort (n=1401) had at least admission between 2007 and 2014, accounting for 11 012 admissions or 1.5% of all admissions in their age group. Compared to general population admissions, CP admissions were more costly and more likely to be elective (66% vs 57%; p<0.001), medical (71% vs 57%; p<0.001), and to take place in metropolitan hospitals (92% vs 78%; p<0.001). Increased CP severity and complexity were associated with having more admissions and a higher proportion of admissions attributable to respiratory illness. INTERPRETATION By linking with administrative data sets, CP registers may be useful for health services research and inform health service delivery.

Abstract
AIM To estimate epidemiological risk factors for cerebral palsy (CP) in children. METHODS A N:M matched case control study was conducted in 114 persons with CP and 1286 controls. Relevant data were collected using a maternal self-design questionnaire. Univariate logistic regression and multivariate conditional logistic regression analyses were performed using SPSS. RESULTS Univariate analysis has yielded 20 significant risk factors for CP. Advanced maternal age (30 years or older) at childbirth (adjusted odds ratio (OR) 1.63, 95% confidence interval (CI) 0.98-2.72), alcohol consumption during pregnancy (adjusted OR 4.17, 95% CI 1.23-14.08), living in the countryside (adjusted OR 1.71, 95% CI 1.18-2.48), father's occupational exposure to harmful substances (adjusted OR 3.34, 95% CI 1.61-6.93) and multiple births (adjusted OR 3.10, 95% CI 1.65-5.84) were found to be risk factors for CP by multivariate analysis. On the other side, high mother's education level (adjusted OR 0.60, 95% CI 0.46-0.76), folic acid supplements (adjusted OR 0.50, 95% CI 0.30-0.82), and high birth hospital level (adjusted OR 0.68, 95% CI 0.52-0.90) were found to be protective factors. CONCLUSION Although the important risk factors of CP focus on gestation at birth and perinatal events, the incidence could probably be further lowered, if potential risk factors identified in this study are considered.

Abstract
OBJECTIVES To investigate the association between maternal pre-pregnancy BMI and risk of cerebral palsy (CP) in offspring. METHODS The study population consisted of 188 788 children in the Mothers and Babies in Norway and Denmark CP study, using data from 2 population-based, prospective birth cohorts: the Norwegian Mother and Child Cohort Study and the Danish National Birth Cohort. Prepregnancy BMI was classified as underweight (BMI <18.5), lower normal weight (BMI 18.5-22.9), upper normal weight (BMI 23.0-24.9), overweight (BMI 25.0-29.9), and obese (BMI ≥30). CP diagnoses were obtained from the national CP registries. Associations between maternal prepregnancy BMI and CP in offspring were investigated by using log-binomial regression models. RESULTS The 2 cohorts had 390 eligible cases of CP (2.1 per 1000 live-born children). Compared with mothers in the lower normal weight group, mothers in the upper normal group had a 40% excess risk of having a child with CP (relative risk [RR], 1.35; 95% confidence interval [CI], 1.03-1.78). Excess risk was 60% (RR, 1.56; 95% CI, 1.21-2.01) for overweight mothers and 60% (RR, 1.55; 95% CI 1.11-2.18) for obese mothers. The risk of CP increased ∼4% for each unit increase in BMI (RR, 1.04; 95% CI, 1.02-1.06). Estimates changed little with adjustment for mother's occupational status, age, and smoking habits. CONCLUSIONS Higher prepregnancy maternal BMI was associated with increased risk of CP in offspring.

Abstract
OBJECTIVES To assess the incidence of cerebral palsy among children born to mothers who had their pregnancy complicated by a motor vehicle crash. DESIGN Retrospective longitudinal cohort analysis of children born from 1 April 2002 to 31 March 2012 in Ontario, Canada. PARTICIPANTS Cases defined as pregnancies complicated by a motor vehicle crash and controls as remaining pregnancies with no crash. MAIN OUTCOME Subsequent diagnosis of cerebral palsy by age 3 years. RESULTS A total of 1 325 660 newborns were analysed, of whom 7933 were involved in a motor vehicle crash during pregnancy. A total of 2328 were subsequently diagnosed with cerebral palsy, equal to an absolute risk of 1.8 per 1000 newborns. For the entire cohort, motor vehicle crashes correlated with a 29% increased risk of subsequent cerebral palsy that was not statistically significant (95% CI -16 to +110, p=0.274). The increased risk was only significant for those with preterm birth who showed an 89% increased risk of subsequent cerebral palsy associated with a motor vehicle crash (95% CI +7 to +266, p=0.037). No significant increase was apparent for those with a term delivery (95% CI -62 to +79, p=0.510). A propensity score-matched analysis of preterm births (n=4384) yielded a 138% increased relative risk of cerebral palsy associated with a motor vehicle crash (95% CI +27 to +349, p=0.007), equal to an absolute increase of about 10.9 additional cases per 1000 newborns (18.2 vs 7.3, p=0.010). CONCLUSIONS Motor vehicle crashes during pregnancy may be associated with an increased risk of cerebral palsy among the subgroup of cases with preterm birth. The increase highlights a specific role for traffic safety advice in prenatal care.

Abstract
BACKGROUND Chorioamnionitis is a risk factor for cerebral palsy. The relationship between extra-amniotic infections and cerebral palsy is less well studied. We examined maternal intra-amniotic and extra-amniotic infections and risk of cerebral palsy in the child. METHODS Among a retrospective cohort of 6 million Californian births, 1991-2001, we analyzed administrative maternal and newborn hospital discharge abstracts linked to records of all children receiving services for cerebral palsy at the California Department of Developmental Services. We identified maternal hospital diagnoses of intra-amniotic (chorioamnionitis) and extra-amniotic (other genitourinary and respiratory) infections occurring up to 12 months before delivery. Using multivariable logistic regression, we determined the independent association between maternal infections and cerebral palsy, adjusting for infant sex, maternal age, race, education, socioeconomic status, and obesity. RESULTS About 5.5% of mothers had a hospital discharge diagnosis of at least one of the following: chorioamnionitis (2.0%), other genitourinary (3.1%), and respiratory infection (0.6%). An infection diagnosis was more common in mothers of the 8473 infants with cerebral palsy than in mothers of unaffected children (13.7% vs 5.5%, P < 0.001). All three types of maternal infections (chorioamnionitis, odds ratio [OR] 3.1, 95% confidence interval [CI] 2.9-3.4; other genitourinary infection, OR 1.4, 95% CI 1.3-1.6; and respiratory infection, OR 1.9, 95% CI 1.5-2.2) were associated with cerebral palsy in multivariable analyses. Maternal extra-amniotic infections, whether diagnosed during prenatal or birth hospitalizations, conferred an increased risk of cerebral palsy. CONCLUSIONS Maternal extra-amniotic infections diagnosed in the hospital during pregnancy are associated with a modestly increased risk of cerebral palsy in the child.

Abstract
Studies have noted several factors associated with the occurrence of Cerebral Palsy (CP), yet considerable uncertainty remains about modifiable factors related to disease onset. A systematic review was performed to identify existing systematic reviews and primary studies pertaining to targeted factors associated with the onset of CP. The following databases were searched: MEDLINE, MEDLINE In Process, EMBASE, PsycINFO, Scopus, Web of Science, Cochrane Database of Systematic Reviews, CINHAL, ProQuest Dissertations & Theses, Huge Navigator, AARP Ageline. Variations of MeSH and keyword search terms were used. Critical appraisal was conducted on selected articles. Data extraction targeted reported factors, risk estimates, and 95% confidence intervals (CI). Findings identified two systematic reviews and three meta- analyses, as well as 83 studies of case control, cohort, and cross-sectional methodological designs. Selected studies indicated that lower gestational age was associated with the onset of CP. Medical diagnoses for the mother, in particular chorioamnionitis, was found to be positively associated with onset of CP. Preeclampsia was reported to be either inconclusive or positively associated with CP onset. Low birth weight predominantly indicated a positive association with the onset of CP, while male gender showed mixed findings. The combination of male gender with pre-term or low birth weight was also found to be positively associated with CP. Evidence was identified in the literature pertaining to specific factors relating to the onset of CP, in particular showing positive associations with lower gestational age and low birth weight.

Abstract
Objective The aim of this study was to identify the relevant obstetric factors for cerebral palsy (CP) after 33 weeks’ gestation in Japan. Study design This retrospective case cohort study (1:100 cases and controls) used a Japanese national CP registry. Obstetric characteristics and clinical course were compared between CP cases in the Japan Obstetric Compensation System for Cerebral Palsy database and controls in the perinatal database of the Japan Society of Obstetrics and Gynecology born as live singleton infants between 2009 and 2011 with a birth weight ≥ 2,000 g and gestation ≥ 33 weeks. Results One hundred and seventy-five CP cases and 17,475 controls were assessed. Major relevant single factors for CP were placental abnormalities (31%), umbilical cord abnormalities (15%), maternal complications (10%), and neonatal complications (1%). A multivariate regression model demonstrated that obstetric variables associated with CP were acute delivery due to non-reassuring fetal status (relative risk [RR]: 37.182, 95% confidence interval [CI]: 20.028–69.032), uterine rupture (RR: 24.770, 95% CI: 6.006–102.160), placental abruption (RR: 20.891, 95% CI: 11.817–36.934), and preterm labor (RR: 3.153, 95% CI: 2.024–4.911), whereas protective factors were head presentation (RR: 0.199, 95% CI: 0.088–0.450) and elective cesarean section (RR: 0.236, 95% CI: 0.067–0.828). Conclusion CP after 33 weeks’ gestation in the recently reported cases in Japan was strongly associated with acute delivery due to non-reassuring fetal status, uterine rupture, and placental abruption.

Abstract
Children of obese mothers are at increased risk of developmental adversities. Maternal obesity is linked to an inflammatory in utero environment, which, in turn, is associated with neurodevelopmental impairments in the offspring. This is an integrated mechanism review of animal and human literature related to the hypothesis that maternal obesity causes maternal and fetal inflammation, and that this inflammation adversely affects the neurodevelopment of children. We propose integrative models in which several aspects of inflammation are considered along the causative pathway linking maternal obesity with neurodevelopmental limitations.
