The efficacy of Equine Assisted Therapy intervention in gross motor function, performance, and spasticity in children with Cerebral Palsy.

Purpose: To evaluate the efficacy of Equine Assisted Therapy in children with Cerebral Palsy, in terms of gross motor function, performance, and spasticity as well as whether this improvement can be maintained for 2 months after the end of the intervention. Methods: Children with Cerebral Palsy participated in this prospective cohort study. The study lasted for 28 weeks, of which the equine assisted therapy lasted 12 weeks taking place once a week for 30 min. Repeated measures within the subject design were used for the evaluation of each child's physical performance and mental capacity consisting of six measurements: Gross Motor Function Measure-88 (GMFM-88), Gross Motor Performance Measure (GMPM), Gross Motor Function Classification System (GMFCS), Modified Ashworth Scale (MAS) and Wechsler Intelligence Scale for Children (WISC III). Results: Statistically significant improvements were achieved for 31 children in Gross Motor Function Measure and all its subcategories (p < 0.005), also in total Gross Motor Performance Measure and all subcategories (p < 0.005). These Gross Motor Function Measure results remained consistent for 2 months after the last session of the intervention. Regarding spasticity, although an improving trend was seen, this was not found to be statistically significant. Conclusion and implications: Equine Assisted Therapy improves motor ability (qualitatively and quantitatively) in children with Cerebral Palsy, with clinical significance in gross motor function.

Growth trajectories during infancy have a significant impact on body composition in childhood.

Evidence supports that growth trajectory during infancy has a major impact on body composition. We aimed to examine body composition in children born small for gestational age (SGA) or appropriate for gestational age (AGA) adjusted for postnatal growth velocity. We enrolled 365 children, 75 SGA and 290 AGA, aged 7 to 10 years, examining anthropometrics, skinfold thickness, and body composition using bioelectrical impedance analysis. Growth velocity was defined as rapid or slow (weight gain > or <0.67 z-scores, respectively). Gestational age, sex, delivery mode, gestational diabetes, hypertension, nutrition, exercise, parental body mass index (BMI), and socioeconomic status were considered. At a mean of 9 years of age, SGA compared with AGA-born children, had significantly lower lean mass. BMI was negatively associated with SGA status (beta = 0.80, P = .046), after adjusting for birth weight, delivery mode, and breastfeeding. The lean mass index was negatively associated with SGA status (beta = 0.39, P = .018), after adjusting for the same factors. SGA-born participants with slow growth velocity had significantly lower lean mass in comparison to AGA-born counterparts. SGA-born children with rapid compared with those with slow growth velocity had significantly higher absolute fat mass. BMI was negatively associated with a slow postnatal growth pattern (beta = 0.59, P = .023), and the lean mass index was negatively associated with a slow postnatal growth pattern (beta = 0.78, P = .006), after adjusting for the same factors. In conclusion, SGA-born children presented a lower lean mass in comparison to AGA-born counterparts, whereas BMI and lean mass index were negatively associated with slow postnatal growth velocity.

Measuring parental stress, illness perceptions, coping and quality of life in families of children newly diagnosed with autism spectrum disorder.

BACKGROUND: A variety of psychosocial factors have been shown to affect the quality of life of families (FQoL). AIM: This study aimed to assess the impact of mother's demographic characteristics, parental stress, illness perceptions about autism spectrum disorder (ASD), coping strategies, ASD severity and time since diagnosis on FQoL during the initial period following diagnosis (≤6 months). METHOD: Fifty-three mothers of children newly diagnosed with ASD completed the Beach Center Family Quality of Life Scale, the Autism Parenting Stress Index, the Brief Illness Perception Questionnaire and the Brief Coping Orientation to Problems Experienced Inventory. A descriptive analysis was conducted on the demographic characteristics of the family. Eta coefficients and Pearson's analysis were used to determine the associations between the variables and the FQoL dimensions. Hierarchical regression was used to determine whether variables explained a statistically significant family quality of life variance. RESULTS: Pearson's analysis and eta coefficients indicated several correlations. Hierarchical regression analysis showed that higher parental stress related to core autism symptoms was associated with poorer FQoL (95% CI -0.08 to -0.02, P = 0.001), and higher perceived treatment control was associated with better FQoL (95% CI 0.04-0.16, P = 0.001). In addition, stronger perceived personal control was associated with higher physical/material well-being (95% CI 0.01-0.16, P = 0.022) and higher disability-related support (95% CI 0.30-0.61, P = 0.001). Higher family monthly income was associated with better FQoL (95% CI 0.08-0.027, P = 0.000), whereas marital status (divorced mother) was correlated with poorer FQoL (95% CI -0.68 to -0.16, P = 0.002). CONCLUSIONS: Interventions should emphasise managing the disorder's characteristics and implementing psychoeducational and supportive programmes for parents, immediately after the diagnosis, to enhance FQoL.

Is small for gestational age status independently correlated with body composition during childhood?

This study aims to examine if small for gestation age (SGA) status is correlated with alterations in body composition at prepuberty, independently of other factors, comparing SGA-born children with appropriate for gestational age (AGA)-born children. We examined anthropometrics, waist circumference, body mass index (BMI), six skinfold thickness, and body composition using the method of bioelectrical impedance in 636 children aged 7 to 10 years. We also considered age, gender, birth mode, mother's age, prepregnancy weight, weight gain during pregnancy, social status, parental BMI, type of feeding, and daily exercise. We examined 636 children at a mean age of 9 years: 106 SGA-born and 530 AGA-born children. SGA as compared to AGA-born children had a lower BMI z-score (0.26 ± 0.89 kg/cm2 vs 0.46 ± 0.84 kg/cm2, p < 0.050) and a lower lean mass, although that was not statistically significant (24.0 ± 6.6 kg vs 25.6 ± 6.4 kg, p < 0.100). SGA-born children presented no difference in waist circumference or fat mass in comparison to children born AGA. Logistic regression analysis revealed a strong independent negative association between SGA status and BMI (beta = - 2.33, OR = 0.70 p = 0.019) and SGA status and lean mass (beta = - 2.43, OR = 0.95 p = 0.010).  Conclusion: Our findings suggest that SGA-born children had a lower BMI as compared to AGA-born subjects, whereas SGA status was negatively associated with BMI and lean mass. What is Known: • Deviant birth weight for gestation has been associated with an increased risk of childhood adiposity. • Evidence remains scarce on whether small for gestational age status affects body composition and obesity later in childhood. What is New: • Among school-aged children, small for gestational age subjects had a lower body mass index as compared to appropriate for gestational age counterparts, whereas small for gestational age status was negatively associated with body mass index and lean mass. • A meticulous observation is needed during childhood in children born with deviant birth weight.

Validation of the Greek version of the Affiliate Stigma Scale among mothers of children with autism spectrum disorder.

BACKGROUND: Caregivers of children with autism spectrum disorder (ASD) are sensitive to the internalisation of the stigma, known as affiliate stigma, resulting in reduced self-esteem, isolation and poor psychological well-being. AIMS: This study aims to validate the Greek version of the Affiliate Stigma Scale (ASS) among mothers of children with ASD. METHOD: The translated version of ASS in Greek was administered to 53 mothers of children newly diagnosed with ASD in two time periods: 1-6 months from diagnosis (time point 1) and 12 months from the initial assessment (time point 2). The control group consisted of 62 mothers of typically developing children. RESULTS: The ASS total mean score revealed a moderate level of stigma to the ASD group in both assessments. The reliability measures by item showed a satisfactory composite reliability (affective 0.828, cognitive 0.833, behaviour 0.857). Cronbach's alpha revealed that the estimated internal consistency was excellent (α = 0.888), and it found a high positive item-total correlation. Receiver operating characteristic analysis results indicated a statistically significant positive discrimination (area under the curve 0.849, P = 0.000) between the groups. The cut-off point was 31.00, with a sensitivity of 0.849 and a 1 - sensitivity of 0.258. CONCLUSIONS: The proposed version of the ASS has good psychometric properties and is valid and reliable for measuring affiliate stigma among caregivers of children with ASD in Greece. Health professionals can use it to assess and understand the stigma experienced by caregivers of children with ASD, and design appropriate interventions to reduce their affiliate stigma.

C-reactive protein in infants with no evidence of early-onset sepsis.

OBJECTIVE: C-reactive protein (CRP) is one of the most extensively used biomarkers in the investigation of early-onset sepsis (EOS). Current evidence suggests the normal kinetics of serum CRP should be considered when evaluating infants for presumable EOS. The current study aimed to evaluate the CRP kinetics, and to establish percentiles in a cohort of term and near-term infants with no evidence of confirmed or clinical EOS. METHODS: We retrospectively reviewed the medical records of all neonates ≥34 weeks' gestation screened for presumable EOS, from January until December 2019. We also recorded the clinical management, the blood culture, serial CRP, and white blood cell count analysis of each infant. All infants that received antibiotics for confirmed or presumed EOS were excluded from the analysis. RESULTS: During the study period, 145 infants were detected; 109 (75%) term and 36 (25%) preterm. Term infants had significantly higher median values of CRP at all time points in comparison to preterm infants. Term infants presented a significant rise of CRP at 24 and 36 h, with a peak at 24 h (median 4 (range 1-12) mg/L). Preterm infants had a significant rise of CRP at 24 but not at 36 h, with a peak at 24 h (median 3 (range 1-9) mg/L). In term infants, the 90th percentile of CRP at 24 h was 10.80 mg/L and the 97th percentile was 12.00 mg/L. In preterm infants, the 90th percentile of CRP at 24 h was 7.60 mg/L and the 97th percentile was 8.00 mg/L. CONCLUSIONS: Term and near-term asymptomatic infants had a rise in CRP during the first days of life. Term infants had a more pronounced CRP response in comparison to preterm infants.

Association of fluid overload with patent ductus arteriosus during the first postnatal day.

BACKGROUND: Evidence examining the association of over-hydration during early life with haemodynamically significant patent ductus arteriosus (hsPDA) and other morbidities is limited. Our aim was to evaluate the association of fluid overload during the first postnatal day with hsPDA and common neonatal morbidities such as bronchopulmonary dysplasia in preterm infants. METHODS: A retrospective cohort study was conducted enrolling infants ≤30 weeks' gestation and ≤1500 grams' birth weight, admitted to a tertiary Neonatal Unit. We calculated the fluid balance and we estimated the incidence of infants with fluid overload ≥5% during the first postnatal day, evaluating any possible correlation with hsPDA. RESULTS: 103 infants of 27.3±1.6 weeks' gestation and 1009±225 grams' birth weight were enrolled; of whom 32 (31%) were diagnosed with HsPDA. Fluid overload during the first postnatal day was recorded in 42 infants (41%). Infants with fluid overload were diagnosed with hsPDA in 48%, compared to 20% of infants without fluid overload (p=0.004). No differences were recorded in the development of bronchopulmonary dysplasia or survival. Fluid overload of ≥5% was significantly correlated with hsPDA (r=0.37, p=0.003) and had an independent contribution to the risk of hsPDA (OR 1.17, 95% CI 1.05-1.58), irrespective of other perinatal factors. CONCLUSIONS: In preterm infants, fluid overload ≥5% is significantly associated with hsPDA, therefore, fluid management during the first postnatal day should be closely regulated.

A systematic review indicates an association between birth weight and body fat in childhood.

AIM: To summarise the existing evidence regarding the body fat of small or large for gestation subjects, evaluated from birth up to 18 years of age. METHODS: The PRISMA guidelines were adopted for the current systematic review, including studies having evaluated body fat with bioelectrical impedance analysis, air displacement plethysmography, dual-energy X-ray absorptiometry or magnetic resonance imaging. RESULTS: A total of 31 studies was included. The balance of evidence suggests that small for gestation infants have decreased fat mass at birth; postnatally they experience increased adiposity. In the long term, however, the evidence is inconclusive, since some studies suggest that foetal-restricted children with increased catch-up growth are at increased risk of fat accumulation, whereas other studies suggest a neutral or even negative association. Large for gestation infants have increased fat mass at birth, but in the long term, they have a lower body fat ratio, especially when they develop a catch-down growth. CONCLUSION: Some studies suggested that foetal-restricted children with increased catch-up growth are at increased risk of later adiposity, while other studies suggested a neutral or negative association. Given that the evidence is inconclusive, further studies are warranted. Large for gestation subjects have lower body fat when they develop catch-down growth.

A comparison between risk-factor guidance for neonatal early-onset sepsis and Kaiser Permanente sepsis risk calculator in a Greek cohort.

BACKGROUND: The management of neonates with early-onset sepsis (EOS) is based on maternal risk factors and infant clinical indications. An online sepsis risk calculator (SRC) has been established taking into consideration how clinical appearance modifies the initial risk for EOS. AIMS: To compare our clinical practice based on risk-factor guidance with that projected through the application of the SRC. STUDY DESIGN: Retrospective cohort study. METHODS: All neonates ≥34 weeks' gestation, during 01/2019-8/2020. The SRC was applied retrospectively to determine the recommendation. EOS was defined based on a positive blood or cerebrospinal fluid culture-proven infection within 72 h of age. Clinical sepsis was defined according to the European Medicine Agency criteria. OUTCOME MEASURES: Differences on antibiotic administration and management. RESULTS: Overall, 2084 infants were identified, of whom 150 (7%) received antibiotics. Of them, 34 infants were diagnosed with clinical sepsis, while one was diagnosed with culture positive-proven EOS. Applying SRC, 87 (4%) infants would have received antibiotics. Clinical sepsis was diagnosed in 29 infants, while one infant had culture positive-proven EOS. Sixty-seven of 150 (45%) infants that received antibiotics would not have been treated based on SRC; five infants that developed clinical sepsis would have been missed with SRC. A 99.7% agreement between both guidance was found regarding infants not indicated for antibiotics. SRC application led to an absolute reduction of antibiotic administration by 2.93% (95% CI 2.19-3.75), p < 0.0001. CONCLUSIONS: The adoption of SRC would have significantly reduced antibiotic usage; however, a significant portion of cases with clinical EOS would have been missed.

Effects of long-term antiepileptic polytherapy on bone biochemical markers in ambulatory children and adolescents and possible benefits of vitamin D supplementation: a prospective interventional study.

PURPOSE: Our aim was to investigate any adverse effects of long-term polytherapy (VPA and add-on-therapy) on bone biochemical markers in ambulatory children and adolescents with epilepsy and the possible benefits of vitamin D supplementation on the same markers. METHODS: In this prospective interventional study, the levels of 25(OH)D and the bone turnover markers of CrossLaps (CTX), total alkaline phosphatase (tALP), osteoprotegerin (OPG), and the receptor activator for nuclear factor kB (RANK) ligand (sRANKL) were determined in forty-two ambulatory children with epilepsy on polytherapy (valproic acid + one or more other from levetiracetam, topiramate, lamotrigine, or rufinamide). The same markers were assessed after a year's supplementation of vitamin D (400 IU/d) and were compared with those of clinically healthy controls. The respective mean (±SD) ages were 11.9 ±â€¯4.6 and 11.4 ±â€¯4.4 yrs. RESULTS: The basal mean 25(OH)D levels in the patients did not differ from controls (23.9 ±â€¯11.5 vs 27.4 ±â€¯13.3 ng/ml), but increased significantly after the vitamin D intake (31.1 ±â€¯13.3 ng/ml, p < 0.01). In parallel, basal serum CTX levels were found to be significantly lower in the patients than controls (0.89 ±â€¯0.63 vs 1.22 ±â€¯0.58 ng/ml, p < 0.02), but not tALP. Osteoprotegerin was higher in the patients (5.7 ±â€¯7.7 pmol/L vs 2.6 ±â€¯1.0 pmol/L, p < 0.03), while sRANKL did not differ. After vitamin D, the CTX levels increased to comparable levels in controls (0.99 ±â€¯0.57 ng/ml), and those of OPG decreased to levels that did not differ from controls (4.9 ±â€¯5.1 pmol/L). The ratio of OPG/sRANKL was higher in patients than controls before treatment (0.030 ±â€¯0.045 vs 0.009 ±â€¯0.005, p < 0.03), but decreased (0.026 ±â€¯0.038) to comparable values in controls later. CONCLUSIONS: These findings imply a lower bone turnover in the young patients on long-term polytherapy (VPA and add-on-therapy), but after one year's vitamin D intake, bone biochemical markers improved.

Are thyroid function tests in neonates born to mothers with hypothyroidism clinically useful?

Thyroid function tests from all babies born to mothers with hypothyroidism (381 neonates) during a 6-year period, were collected and examined against findings of the universal screening test. No difference was found between the results of bloodspot test and later blood test. Additional blood tests for thyroid function in this population of neonates seem to be without clinical value and may be discontinued.

Vitamin D supplementation and bone markers in ambulatory children on long-term valproic acid therapy. A prospective interventional study.

PURPOSE: Our aim was to investigate any adverse effects of long-term valproic acid (VPA) therapy on bone biochemical markers in ambulatory children and adolescents with epilepsy, and the possible benefits of vitamin D supplementation on the same markers. METHODS: In this single center, the prospective interventional study levels of 25-hydroxyvitamin D (25OHD) and the bone turnover indices of Crosslaps (CTX), total alkaline phosphatase (tALP), osteoprotegerin (OPG), and the receptor activator for nuclear factor kB (RANK) ligand (sRANKL) were assessed before and after one year of vitamin D intake (400 IU/d) and were compared with those of clinically healthy controls. Fifty-four ambulatory children with mean (±standard deviation [SD]) age 9.0 ±â€¯4.5 yrs on VPA (200-1200 mg/d) long-term monotherapy (mean: 3.2 ±â€¯2.6 yrs) were studied, before and after a year's vitamin D intake (400 IU/d). RESULTS: Nearly half of the cases were vitamin D insufficient/deficient with mean levels 23.1 ±â€¯12.8 vs 31.8 ±â€¯16.2 ng/mL of controls (p = 0.004) and after the year of vitamin D intake increased to 43.2 ±â€¯21.7 ng/mL (p < 0.0001). In parallel, serum CTX and tALP had a decreasing trend approaching control levels but OPG and sRANKL did not change and were not different from controls. However, after vitamin D intake, a positive correlation was seen between 25OHD and OPG but not before. CONCLUSIONS: The findings imply a higher bone turnover in the young patients on long-term VPA therapy that decreased after vitamin D intake.

Therapeutic Effects of Horseback Riding Interventions: A Systematic Review and Meta-analysis.

OBJECTIVE: Equine-assisted therapies, such as therapeutic riding and hippotherapy, are believed to have positive physical and emotional effects in individuals with neuromotor, developmental, and physical disabilities. The purpose of this review was to determine whether therapeutic riding and hippotherapy improve balance, motor function, gait, muscle symmetry, pelvic movement, psychosocial parameters, and the patients' overall quality of life. DESIGN: In this study, a literature search was conducted on MEDLINE, CINAHL, MBASE, SportDiscus, Cochrane Database of Systematic Reviews, Cochrane Controlled Trials Register, PEDro, DARE, Google Scholar, and Dissertation Abstracts. Only studies with a control/comparison group or self-controlled studies performing preintervention and postintervention assessment were included. Excluded were (1) studies not providing data on baseline score or end-point outcome, (2) single-subject studies, (3) studies providing only qualitative data, and (4) studies that used a mechanical horse. Sixteen trials were included. The methodologic quality of each study was evaluated using Downs and Black quality assessment tool. RESULTS: Most of the studies showed a trend toward a beneficial effect of therapeutic riding and hippotherapy on balance and gross motor function. The meta-analysis showed improvement in both the Berg Balance Scale and the Gross Motor Function Measure in therapeutic riding and hippotherapy programs. CONCLUSION: Programs such as therapeutic riding and hippotherapy are a viable intervention option for patients with balance, gait, and psychomotor disorders.

Low-birth-weight, but not catch-up growth, correlates with insulin resistance and resistin level in SGA infants at 12 months.

OBJECTIVE: To investigate the insulin resistance status in SGA infants at 12 months and its relationship with auxological and metabolic parameters. METHODS: One group of 45 SGA and one of 50 appropriate for gestational age infants were followed from birth to the end of the first year of life. At 12 months, skinfold thickness, waist circumference, and blood levels of glucose, insulin, adiponectin, leptin, resistin, visfatin, retinol-binding protein 4, IGFs, lipids profile were determined, and the HOMA-IR index was calculated. RESULTS: The SGAs had increased insulin (5.2 ± 2.7 versus 2.9 ± 2.4 µIU/ml, p = 0.012) and HOMA-IR (1.09 ± 0.9 versus 0.59 ± 0.55, p = 0.016). In multiple regression, insulin resistance indices were independently correlated with low-birth-weight (ß = -2.92, p = 0.015 for insulin, ß = -2.98, p = 0.011 for HOMA-IR) but not with catch-up growth in either height or weight or any other metabolic parameter. Resistin was higher in the SGAs (5.1 ± 2.1 versus 3.9 ± 2.1 ng/ml, p = 0.03) and independently correlated with low-birth-weight but not insulin resistance. Resistin was negatively correlated with total cholesterol (R = -0.33, p = 0.007) and positively with lipoprotein(a) (R = 0.49, p = 0.001). CONCLUSION: Low-birth-weight, but not catch-up growth or adiposity tissue hormones, was correlated with insulin resistance at 12 months in non-obese SGA infants. The higher resistin in SGA infants and its correlation with total cholesterol and lipoprotein(a) need further clarification.

UGT1A6- and UGT2B7-related valproic acid pharmacogenomics according to age groups and total drug concentration levels.

AIM: The role of UGT1A6 and UGT2B7 polymorphisms and the impact of total drug plasma concentration in valproic acid (VPA) pharmacogenomics. PATIENTS & METHODS: A total of 134 Greek patients were recruited (76 adults). Patients were genotyped for UGT1A6 19T>G, 541A>G and 552A>C and UGT2B7 802T>C polymorphisms. Patients' demographic and clinical data were registered. Natural logarithm of concentration-to-dose ratio (CDR) was also calculated as the final outcome. RESULTS: No significant genotype-related differences in VPA metabolism were noted among various subgroups. An increased lnCDR ratio was noted in children patients compared with adults suggesting increased metabolic capability in younger ages. CONCLUSION: UGT1A6 and UGT2B7 genotypes were not related to significant changes in VPA metabolism, even after controlling for total drug concentration levels. Younger ages were associated with increased VPA clearance rate.

Diffusion tensor imaging in children with tuberous sclerosis complex: tract-based spatial statistics assessment of brain microstructural changes.

BACKGROUND: There is evidence of microstructural changes in normal-appearing white matter of patients with tuberous sclerosis complex. OBJECTIVE: To evaluate major white matter tracts in children with tuberous sclerosis complex using tract-based spatial statistics diffusion tensor imaging (DTI) analysis. MATERIALS AND METHODS: Eight children (mean age ± standard deviation: 8.5 ± 5.5 years) with an established diagnosis of tuberous sclerosis complex and 8 age-matched controls were studied. The imaging protocol consisted of T1-weighted high-resolution 3-D spoiled gradient-echo sequence and a spin-echo, echo-planar diffusion-weighted sequence. Differences in the diffusion indices were evaluated using tract-based spatial statistics. RESULTS: Tract-based spatial statistics showed increased axial diffusivity in the children with tuberous sclerosis complex in the superior and anterior corona radiata, the superior longitudinal fascicle, the inferior fronto-occipital fascicle, the uncinate fascicle and the anterior thalamic radiation. No significant differences were observed in fractional anisotropy, mean diffusivity and radial diffusivity between patients and control subjects. No difference was found in the diffusion indices between the baseline and follow-up examination in the patient group. CONCLUSION: Patients with tuberous sclerosis complex have increased axial diffusivity in major white matter tracts, probably related to reduced axonal integrity.

The Role of Fast Cell Cycle Analysis in Pediatric Brain Tumors.

Cell cycle analysis by flow cytometry has not been adequately studied in pediatric brain tumors. We investigated the value of a modified rapid (within 6 min) cell cycle analysis protocol for the characterization of malignancy of pediatric brain tumors and for the differentiation of neoplastic from nonneoplastic tissue for possible intraoperative application. We retrospectively studied brain tumor specimens from patients treated at our institute over a 5-year period. All tumor samples were histopathologically verified before flow-cytometric analysis. The histopathological examination of permanent tissue sections was the gold standard. There were 68 brain tumor cases. All tumors had significantly lower G0/G1 and significantly higher S phase and mitosis fractions than normal brain tissue. Furthermore low-grade tumors could be differentiated from high-grade tumors. DNA aneuploidy was detected in 35 tumors. A correlation between S phase fraction and Ki-67 index was found in medulloblastomas and anaplastic ependymomas. Rapid cell cycle analysis by flow cytometry is a promising method for the identification of neoplastic tissue intraoperatively. Low-grade tumors could be differentiated from high-grade tumors. Thus, cell cycle analysis can be a valuable adjunct to the histopathological evaluation of pediatric brain tumors, whereas its intraoperative application warrants further investigation.
