Executive function impairment is associated with low serum vitamin D levels in children with epilepsy

PurposeExecutive function (EF) impairment and vitamin D deficiency are common clinical features among children with epilepsy (CWE). Recently, vitamin D has become a potential modification factor that affects cognitive status in individuals with neurological disorders. In this study, we investigated the association between EF status and vitamin D levels in patients with CWE. MethodsIn total, 79 CWE patients and 39 healthy controls (HCs) were recruited in this study. Each participant’s EF was assessed using the Behavior Rating Inventory of Executive Function-Parent form (Brief-P), and the serum level of 25-OH vitamin D was measured using liquid chromatography-tandem mass spectrometry (LC-MS/MS). ResultsCompared with those in the HC group, the CWE group had higher T scores of Brief-P scale, including global executive composite (GEC) (51.01(45.12, 60.69) vs. 44.08(39.24, 49.96), p＜0.001), behavioral regulation index (BRI) (51.29(45.67, 59.13) vs. 45.67(40.06, 51.29), p＜0.001), metacognition index (MI) (51.83(46.77, 59.43) vs. 46.13(40.44, 51.83), p＜0.001), and lower serum vitamin D (14.85(10.24,23.2) vs. 22.5(16.91,30), p＜0.001) levels. After adjustment for covariates, multivariate linear regression models suggested that for every 1 ng/ml increase in vitamin D, the GEC, BRI, and MI would decrease by 0.52 (Coeff = -0.48; 95 % CI = -0.69, −0.26; p = 0.000), 0.45 (Coeff = -0.45; 95 % CI = -0.69, −0.20; p = 0.000), and 0.47 (Coeff = -0.45; 95 % CI = -0.67, −0.22; p = 0.000), respectively. ConclusionThere may be an association between decreased vitamin D levels and EF impairment in CWE. Future research should consider longitudinal variations in EF related to improving vitamin D deficiency.

Patterns of proactive interference in CVLT-II: evidence of a low-organized, disorganized, and highly organized learning style

ABSTRACT Objective Previous studies have interpreted proactive interference (PI) either as indicating executive dysfunction or a normal process indicating deep level encoding. We investigated these competing models of PI in a large clinical sample using cluster analyses. We expected to find clusters defined by high PI but otherwise characterized by either EF impairment or of good memory performance. Method File records of 731 patients with neurological or psychiatric disorders were analyzed. PI-scores, false positive recognition errors, and semantic organization scores on the California Verbal Learning Test-II (CVLT-II) were subjected to cluster analyses. Clusters were compared regarding buildup and release from PI, memory performance and strategy measures, measures of intelligence, EF, and processing speed. Results The analyses revealed six analyzable clusters. Two clusters showed no buildup of PI and normal release from PI. Discriminability was impaired both in List A and B. Learning acquisition and speeded measures of EF were reduced. One cluster showed both buildup of PI and problems with releasing from PI, and particularly impaired discriminability of List B. Semantic organization was low. Learning consolidation and EF speeded measures were impaired. Two other clusters showed buildup of PI, but no problem with release. Learning was highly organized, and they showed good memory and normal neuropsychological performance. Conclusions Results shows differentiation between a low organized EF dysfunction pattern with no PI, a disorganized PI pattern also indicating EF dysfunction and a highly organized pattern where PI seems to be the price to pay for high effort put into the learning process.

Executive functioning in preschoolers with 22q11.2 deletion syndrome and the impact of congenital heart defects

BackgroundExecutive functioning (EF) is an umbrella term for various cognitive functions that play a role in monitoring and planning to effectuate goal-directed behavior. The 22q11.2 deletion syndrome (22q11DS), the most common microdeletion syndrome, is associated with a multitude of both somatic and cognitive symptoms, including EF impairments in school-age and adolescence. However, results vary across different EF domains and studies with preschool children are scarce. As EF is critically associated with later psychopathology and adaptive functioning, our first aim was to study EF in preschool children with 22q11DS. Our second aim was to explore the effect of a congenital heart defects (CHD) on EF abilities, as CHD are common in 22q11DS and have been implicated in EF impairment in individuals with CHD without a syndromic origin.MethodsAll children with 22q11DS (n = 44) and typically developing (TD) children (n = 81) were 3.0 to 6.5 years old and participated in a larger prospective study. We administered tasks measuring visual selective attention, visual working memory, and a task gauging broad EF abilities. The presence of CHD was determined by a pediatric cardiologist based on medical records.ResultsAnalyses showed that children with 22q11DS were outperformed by TD peers on the selective attention task and the working memory task. As many children were unable to complete the broad EF task, we did not run statistical analyses, but provide a qualitative description of the results. There were no differences in EF abilities between children with 22q11DS with and without CHDs.ConclusionTo our knowledge, this is the first study measuring EF in a relatively large sample of young children with 22q11DS. Our results show that EF impairments are already present in early childhood in children with 22q11DS. In line with previous studies with older children with 22q11DS, CHDs do not appear to have an effect on EF performance. These findings might have important implications for early intervention and support the improvement of prognostic accuracy.

White matter microstructure and executive functions in congenital heart disease from childhood to adulthood: A pooled case–control study

ABSTRACT Congenital heart disease (CHD) patients are at risk for alterations in the cerebral white matter microstructure (WMM) throughout development. It is unclear whether the extent of WMM alterations changes with age, especially during adolescence when the WMM undergoes rapid maturation. We investigated differences in WMM between patients with CHD and healthy controls from childhood until early adulthood in a pooled sample of children, adolescents, and young adults. The association between WMM and EF was assessed. Patients with CHD (N=78) and controls (N=137) between 9 and 32 years of age underwent diffusion tensor imaging and an executive function test-battery. Mean fractional anisotropy (FA) was calculated for each white matter tract. Linear regression tested age and group effects (CHD vs control) and their interaction on FA. Relative Variable Importance (RI) estimated the independent contribution of tract FA, presence of CHD, CHD complexity, and parental education to the variability in EF. Mean FA was lower in patients compared to controls in almost all tracts (p between 0.057 and <0.001). WMM alterations in patients were not different depending on age (all interaction effects p>0.074). Predictors of EF were CHD group (RI=43%), parental education (RI=23%), CHD complexity (RI=10%), FA of the hippocampal cingulum (RI=6%) and FA of the corticospinal tract (RI=6%). The lack of group-FA-interactions indicates that the extent of altered FA remains similar across age. Altered FA is associated with EF impairments. CHD is a chronic disease with cerebral and neurocognitive impairments persisting into adulthood and, thus, long-term follow-up programs may improve overall outcome for this population.

Age-Related Variance in Performance versus Ratings of Attention and Impulse Regulation in Children: Implications for the Assessment of ADHD.

Executive function task (EF) deficits are hypothesized to underlie difficulties with self-regulation. However, tasks assessing EF impairments have only been weakly correlated with rating scales that index self-regulation difficulties. A community sample of children and youth aged between 8 and 20 years old were assessed longitudinally. Growth curve analyses and correlations were conducted to better understand how these two types of measures relate to one another across development, as well as the impact of age-related variance. EF was assessed using the Stroop Task and Trail Making test and behavioral ratings of self-regulation were captured using the SWAN scale. EF task performance improved steeply until age 14–15, whereas the SWAN Scale showed small age-related decreases. EF task performance was moderately correlated with age among 8–13-year-olds and to a lesser extent among 14–20-year-olds. SWAN scores were not significantly related to age in either group. Correlations were similar in an ADHD “at-risk” subgroup. EF task performance and parent ratings of attention regulation have different developmental trajectories, which may partly explain why correlations are low to modest in these samples. In particular, age-related variance is an important methodological consideration with significant implications for the assessment of self-regulation in children and youth with ADHD.

Inter-Individual Differences in Executive Functions Predict Multitasking Performance - Implications for the Central Attentional Bottleneck.

Human multitasking suffers from a central attentional bottleneck preventing parallel performance of central mental operations, leading to profound deferments in task performance. While previous research assumed that the deferment is caused by a mere waiting time (refractory period), we show that the bottleneck requires executive functions (EF; active scheduling account) accounting for a profound part of the deferment. Three participant groups with EF impairments (dyslexics, highly neurotics, deprived smokers) showed worse multitasking performance than respective control groups. Three further groups with EF improvements (video-gamers, bilinguals, coffee consumers) showed improved multitasking. Finally, three groups performed a dual-task and different measures of EF (reading span, rotation span, symmetry span) and showed significant correlations between multitasking performance and working memory capacity. Demands on EF during multitasking may cause more errors, mental fatigue and stress, with parts of the population being considerably more prone to this.

Executives functions in co-occuring adult attention deficit hyperactivity disorder and alcohol use disorder

IntroductionExecutives functions (EF) are cognitive processes mediating the ability to successfully regulate thoughts and behaviours in order to fulfil a goal. EF impairment has been found both in the Attention Deficit Hyperactivity Disorder (ADHD) and in the Alcohol Use Disorder (AUD). Deficits in EF may have a major impact on patients’ everyday life.ObjectivesThe aim of this study was to evaluate EF in a population with a dual diagnosis of Adult ADHD et AUD. We also evaluated the correlation between EF and the dimensions of quality of life.MethodsFor this observational multicentric study, we included patients with AUD starting long-term residential treatment. We used ASRS v.1.1 to screen for Adult ADHD and DIVA to confirm the diagnosis. We assess EF with BRIEF-A. WHOQoL-BREF was used to evaluate quality of life.Results Our population consists of 49 patients. Adult ADHD prevalence was 24,49%. Impairment score of all EF explored (Inhibition, Shifting, Emotional Control, Self-Monitoring, Initiative, Working Memory, Planning/Organizing, Organization of materials, Task Monitoring) was higher in patients with co-occuring Adult ADHD and AUD than in patients without Adult ADHD (p&lt;0,001). We found strong negative correlation between Psychological Health and impairment score of Inhibition (p&lt;0,001), Emotion Control (p&lt;0,001), Self-Monitoring (p&lt;0,001) and planning/Organizing (p&lt;0,001). The other dimensions of quality of life were poorly correlated to EF impairment.ConclusionsThe prevalence of Adult ADHD in AUD patients is high. When AUD and Adult ADHD coexist, EF impairment is stronger and quality of life is poorer. Psychological health and EF impairment are strongly associated.

Bilingualism in Parkinson’s disease: Relationship to cognition and quality of life

ABSTRACT Some studies have found that bilingualism promotes cognitive reserve. Objective: We aimed to determine whether bilingualism, defined as regularly (i.e. daily) using at least two languages at least since early adulthood, is associated with cognitive advantages in Parkinson’s disease (PD) or whether the possible benefits of bilingualism are lost in the context of PD, possibly affecting quality of life (QoL) and independence. Method: Participants with idiopathic PD (n = 140, mean age = 67.9 [SD = 6.4], 78% men) completed standard neuropsychological tasks evaluating attention/working memory, language, executive function, memory, and visuospatial ability, as well as measures of wellbeing and functional independence. Results: Bilinguals with PD (n = 21) performed worse than monolinguals with PD (n = 92) on attention/working memory and language measures. The between-group differences in attention/working memory were restricted to verbally-based measures. When measured along a continuum, a higher degree of bilingualism was correlated with lower scores on measures of attention/working memory and language. There were no group differences in self- or informant-reported cognitive decline, PD health-related QoL, or functional independence. Conclusions: Bilingualism in PD was not associated with better cognitive performance. Lower scores on language-based measures may reflect a distributed fund of linguistic information across more than one language, lower language proficiency in English, and/or other cultural artifacts. Furthermore, using normative data specific to the dominant language spoken or conducting neuropsychological testing in participants’ self-reported most proficient language may enhance additional studies addressing this topic. Future research may also examine the roles of bilingualism over time and across other neurodegenerative diseases with and without EF impairment to illuminate further the impact of bilingualism on cognition and QoL, and shape culturally and linguistically diverse research and clinical care.

A transdiagnostic examination of anxiety and stress on executive function outcomes in disorders with social impairment

BackgroundExecutive function (EF) difficulties characterise a number of psychiatric conditions and EF impairment may be a predisposing factor and/or consequence of anxiety and stress. The aim of the study was to examine EF factors in a mixed clinical cohort (Autism Spectrum Disorder and Social Anxiety Disorder) characterised by social impairment and investigate the influence of trait anxiety and state-based depression, anxiety and stress. MethodsIn Study 1, a factor analysis identified EF and non-EF latent factor structures (N=205). In Study 2, (N=137) multiple regression analyses investigated the association between trait anxiety and state based depression, anxiety and stress, on EF and non-EF cognitive domains and on the two composite indices of the Behavioural Rating Inventory of Executive Function (BRIEF). ResultsTrait anxiety was associated with better performance on neuropsychological measures of EF while state-based stress was associated with lower EF performance. A dissociation was observed between trait anxiety and state stress on the two behavioural indices of the BRIEF. Depression, anxiety and stress did not predict performance on non-EF cognitive domains. LimitationsThe cross-sectional design precludes cause-effect conclusions, further only self-report measures of affect were utilised and our performance measures of EF did not include a working memory test. ConclusionsThe results demonstrate that trait anxiety and state-based stress influence EF processes across disorders with social impairment. The transdiagnostic efficacy of this finding can facilitate remediation strategies, it may also contribute to individuals with Autism Spectrum Disorder gaining better access to mental health services.

Progression of Normal Flow Low Gradient “Severe” Aortic Stenosis With Preserved Left Ventricular Ejection Fraction

Normal-flow low-gradient severe aortic stenosis (NF-LG-SAS), defined by an aortic valve area (AVA) <1 cm², mean pressure gradient (MPG) <40 mm Hg and indexed stroke volume ≥35 ml/m², is the most prevalent form of low-gradient aortic stenosis (AS) with preserved ejection fraction (PEF). However, the true severity of AS in these patients is controversial. The aim of this Doppler echocardiographic study was to investigate changes over time in the hemodynamic severity of patients with NF-LG-SAS with PEF. We retrospectively identified 96 patients who had 2 Doppler echocardiographic examinations without an intervening event. After a median follow-up of 25 (interquartile range 15 to 52) months, progression was observed, with increased transaortic MPG (from 28 [25 to 33] to 39 [34 to 50] mm Hg; p<0.001), peak aortic jet velocity (from 3.46 [3.20 to 3.64] to 4.01 [3.70 to 4.39] m/s; p<0.001), and decreased AVA (from 0.87 [0.82 to 0.94] to 0.72 [0.62 to 0.81] cm²; p<0.001). Median annual rates of progression were 4.3 (1.7 to 8.1) mm Hg/year, 0.25 (0.08 to 0.44) m/s/year, and -0.05 (-0.10 to -0.02) cm²/year, respectively. There was no significant change in left ventricular ejection fraction over time (p = 0.74). At follow-up, 46 patients (48%) acquired the features of classical high-gradient severe AS (MPG ≥40 mm Hg). This study shows that most patients with NF-LG-SAS with PEF exhibit significant hemodynamic progression of AS severity without EF impairment. These findings suggest that NF-LG-SAS with PEF is an "intermediate" stage between moderate AS and classical high-gradient severe AS requiring close monitoring.

Assessment of right ventricular function by echocardiography in patients with chronic heart failure.

BackgroundThe main focus of most of the studies in heart failure (HF) is the assessment of the left ventricular functions, while the right ventricle was much less studied. Much of this neglect is due to the complexity of anatomy and physiology of the right ventricle which are considered challenges during assessment of RV.Objective[1] To review the alterations of right ventricular dimensions & function associated with chronic heart failure. [2] To predict the prevalence of right ventricular systolic dysfunction in patients with chronic heart failure, based on echocardiographic parameters.Methods100 chronic left sided heart failure patients with LVEF less than 40% were evaluated in Ain Shams University hospitals from April 2015 to March 2016. All patients were subjected to full history taking & clinical evaluation. ECG was done mainly to exclude presence of ischemic heart disease. Complete trans-thoracic echocardiography study was done for assessment of [B] Left ventricular dimensions, systolic and diastolic functions [B] Assessment of the right side of the heart: [1] Measurement of the right ventricular dimensions [basal – mid cavity and the longitudinal diameters]. [2] Right ventricular area and calculation of the fractional area change (FAC). [3] Tricuspid annular plane systolic excursion (TAPSE). [4] Tissue Doppler derived tricuspid lateral annular systolic velocity (S′ wave velocity). [5] Tissue Doppler derived Myocardial Performance Index (MPI) (Tei index). [6] Grading of tricuspid regurgitation severity, and assessment of right ventricular systolic pressure.ResultsRight ventricle was dilated at the basal level in 36% of the studied patients & at the mid cavity level in 23% of the patients. Longitudinal RV diameter was enlarged in 20% of the patients.Right ventricular systolic dysfunction was found in 36% of patients with DCM in the current study. Patients who had right ventricular systolic dysfunction had significantly higher incidence of elevated JVP, significantly lower EF and significantly higher grade of LV Diastolic dysfunction. They showed significantly larger RV dimensions at different levels, significantly worse degree of TR and significantly higher mean value of RVSP.ConclusionsThe occurrence of right ventricular systolic dysfunction in patients with DCM is common [Approaching 40% in this study] and is independent of age and sex, and is proportionate to the degree of LV dilatation, and EF impairment.

Social information processing skills link executive functions to aggression in adolescents with mild to borderline intellectual disability

ABSTRACTExecutive Functions (EFs) have been associated with aggression in children and adolescents. EFs as higher-order cognitive abilities are assumed to affect cognitive functions such as Social Information Processing (SIP). We explored SIP skills as a mediating mechanism linking EFs to aggression in adolescents with mild to borderline intellectual disability (MBID with IQ from 50–84), a high risk group for aggressive behaviors and EF impairments. A total of 153 adolescents (Mage = 15.24, SD = 1.35; 54% male) with MBID participated. Focused attention, behavioral inhibition, and working memory were tested with multiple neurocognitive tasks to define latent EF constructs. Participants responded to a video-based SIP task. A latent construct for aggression was defined by caretaker, teacher, and adolescent self-reports of aggression (Child Behavior Check List, Teacher Report Form, and Youth Self Report). Structural equation modeling was performed to test mediation. Results were consistent with mediation of the relation between focused attention and aggression by SIP, namely via hostile interpretations and self-efficacy for aggression. Behavioral inhibition was linked to aggression, but this relation was not mediated by SIP. The relation between working memory and aggression was mediated by SIP, namely via hostile interpretations, aggressive response generation and via self-efficacy for aggressive responses. Bearing the cross-sectional design in mind, support was found for SIP skills as a mechanism linking EFs, in particular focused attention and working memory, to aggression, providing a viable explanation for the high vulnerability of adolescents with MBID for aggression.

Is damage to the pre-frontal cortex dormant until adolescence, or difficult to detect? Looking for keys that unlock executive functions in children in the wrong place

A range of functions can be negatively affected by pre-frontal cortex (PFC) injury, but observed behavioural and social changes are commonly linked to post-injury changes in executive function. Executive functioning is a complex neuropsychological construct which is further complicated by neuro-developmental processes when applied to children. There is a substantial and continuing evidence base that supports the view that early childhood pre-frontal cortex (PFC) injury results in hidden, dormant, or sleeping effects. In contrast, recent and rapidly accruing contemporary studies provide preliminary evidence that challenge the view that PFC associated impairments are completely ‘hidden’. Studies that examine the various functions of the PFC and differentiate these to provide preliminary evidence to indicate earlier EF development than that which develops upon reaching adolescence, are reviewed here, together with research that identifies early predictors of later EF impairments. It remains that studies of PFC function and/or structural brain-changes are substantially complicated by issues related to definition regarding functions of the PFC, measurement of EF and other PFC-related functions that may be better understood as meta-processes. These issues are discussed in the concluding sections of this paper.

How do assessments of activities of daily living address executive functions: A scoping review

ABSTRACTExecutive functions (EF) allow persons to adapt to situations arising in daily life and can be affected following acquired brain injury (ABI). Measuring the impact of EF impairments on the accomplishment of activities of daily living (ADL) requires specific assessment tools, but choosing the right tool may be difficult.Purpose: To conduct a scoping review on how assessments of ADL address EF and EF impairments in persons with ABI.Method: A scoping review of literature (peer-reviewed and grey literature) published until August 2014 was conducted. Using a systematic procedure, literature was selected, results were charted, and tools were analysed with respect to their goals, underlying models, psychometric properties and applicability. The analysis also included how tools considered components of EF according to Lezak’s model.Results: 12 tools, developed either to assess EF in ADL, independence in ADL considering EF or ADL capacities, were identified and analysed according to multiple criteria.Conclusions: This review provides important information about existing tools to assist in tool selection and clinical decision-making related to ABI and EF.

Executive function after severe childhood traumatic brain injury – Age-at-injury vulnerability periods: The TGE prospective longitudinal study

BackgroundExecutive function (EF) impairment is a major predictor of overall outcome after traumatic brain injury (TBI). TBI severity is a factor of poor outcome, but most studies include a majority of children with mild and moderate TBI. The aims of this study were to estimate EF impairment after severe childhood TBI and to explore factors predicting EF outcome. The secondary aim was to compare recovery trajectories by age-at-injury groups. MethodsThis was a prospective longitudinal study of children with severe TBI who were tested for EFs by performance-based tests and questionnaires at 3, 12 and 24 months. ResultsChildren with TBI (n=65) showed significant impairment in working memory, inhibition, attention and global EF, with little or no recovery at 24 months. For flexibility and performance-based EF score, children were impaired at 3 months only and showed normal scores by 12 months. No impairment was found in planning. At 3 and 24 months, Glasgow Coma Scale score and parental education predicted global EF. Coma length was not a significant predictor of outcome. Age at injury predicted progress in EF, but the relationship was not linear; children 10–12 years old at injury showed better outcome than older and younger children. ConclusionsEFs are impaired after severe TBI in childhood. The relationship between age at injury and outcome is not linear. Relying on only performance-based EF tests can underestimate EF impairment.

Development of Hot and Cold Executive Function in Boys and Girls With ADHD

Objective: To investigate the development of executive function with pronounced emotional salience (hot EF) and less pronounced emotional salience (cold EF) in boys and girls with ADHD relative to typically developing (TD) children. Method: Seventy-five children with ADHD and 47 TD children were assessed with hot and cold EF tests at baseline and after 2 years. Results: Despite considerable maturation, the ADHD group remained impaired on all cold EF tests relative to TD children after 2 years. There was no effect of gender on cold EF test results. Females with ADHD outperformed TD counterparts on hot EF at baseline. Females with ADHD showed deteriorating hot EF performance, while TD counterparts showed improved hot EF performance across time. Conclusion: Enduring cold EF impairments after 2 years may reflect stable phenotypic traits in children with ADHD. Results indicate divergent developmental trajectories of hot EF in girls with ADHD relative to TD counterparts.

Comparison of two cognitive interventions for adults experiencing executive dysfunction post-stroke: a pilot study

Purpose This pilot partially randomised controlled trial compared the feasibility and preliminary efficacy of two promising interventions for persons with executive dysfunction post-stroke: (1) occupation-based strategy training using an adapted version of the Cognitive Orientation to daily Occupational Performance (CO-OP) approach; and (2) Computer-based EF training (COMPUTER training). Method Participants received 16 h of either CO-OP or COMPUTER training. We assessed feasibility and acceptability of each intervention, and change in intervention outcomes at baseline, post-intervention and one-month follow-up. Performance and satisfaction with performance in self-selected everyday life goals were measured by the participant and the significant other-rated Canadian Occupational Performance Measure (COPM). Other intervention outcomes included changes in EF impairment, participation in daily life and self-efficacy. Results Six participants received CO-OP and five received COMPUTER training: one in each group discontinued the intervention for medical reasons unrelated to the intervention. The remaining nine participants completed all 16 sessions. Participants expressed high levels of satisfaction with both interventions. Both treatment groups showed large improvements in self and significant other-rated performance and satisfaction with performance on their goals immediately post-intervention and at follow-up (CO-OP: effect sizes (ES) = 1.6–3.5; COMPUTER: ES = 0.9–4.0), with statistically significant within-group differences in CO-OP (p < 0.05). The COMPUTER group also showed large improvements in some areas of EF impairment targeted by the computerised tasks (ES = 0.9–1.6); the CO-OP group demonstrated large improvements in self-efficacy for performing everyday activities (ES = 1.5). Conclusions Our findings provide preliminary evidence supporting the feasibility of using both CO-OP and COMPUTER training with patients with executive dysfunction post-stroke.Implications for RehabilitationComputerised executive function training and occupation-based strategy training are feasible to deliver and acceptable to persons with executive dysfunction post-stroke.Preliminary evidence suggests that both interventions have a positive impact on real-world outcomes; and, that CO-OP might have a greater impact on improving self-efficacy for performing everyday activities.

Assessment of Executive Functions in Preschool-Aged Children with Autism Spectrum Disorders: Usefulness and Limitation of BRIEF-P in Clinical Practice

This study examines the context of executive functioning in preschool children with Autism Spectrum Disorders (ASDs) and verifies the degree of agreement between the compilation of the Behavior Rating Inventory of Executive Functions-Preschool Version (BRIEF-P) by parents and therapists. To this end, parents and professionals of 46 ASD children aged between 24 and 71 months completed the BRIEF-P in order to highlight the level of agreement between these two different evaluators and then investigate the correlations between executive functions impairment, the degree of autistic symptomatology, the level of cognitive development, the chronological age and the therapy duration. The results showed that parents tend to underestimate the impairment of executive functions in ASD children compared to what estimated by specialized operators. A low level of agreement was found between the two evaluators. Moreover, both for parents and professionals, the EF impairment was not related to the severity of autistic symptoms, assessed with the ADOS-2, while it was correlated to cognitive development in professional evaluations, and to chronological age and therapy duration in parental evaluations. These results indicate that, even if among the pathogenic assumptions about ASDs there has been included also that of the EF impairment, this, if present, does not correlate with the severity of autistic symptoms. With regard to cognitive development, the greater correlation between cognitive and executive impairment seems to be rather obvious. The use of the BRIEF-P completed by parents allows them a greater awareness but does not add clinical data to the diagnosis.

0437: Impact of RV involvement on LV remodeling after acute MI

The purpose of this study was to investigate the impact of the right ventricular involvement as assessed on cardiac MRI (CMR) in patients with reperfused acute myocardial infarction (AMI). 147 patients with reperfused AMI were included in a prospective multicenter study (clinical trials: NCT 01113268). All patients underwent CMR imaging within 4 days following primary percutaneous coronary intervention (PPCI) and at 6 months follow-up. Right and left ventricular volumes and function were retrospectively calculated using dedicated software. Data study consisted of topography and size of myocardial infarction and of the microvascular obstruction measurements. Right and left ventricular remodeling were defined as end-diastolic volume (EDV) increase >20 between immediate CMR and 6-month follow-up. The presence of RV infarction was compared with the prevalence of LV and RV remodeling. All patients were successfully reperfused within first 6 hours after chest pain onset. Location of AMI was as follow: 82 (56%) had anterior MI, 44 (30%) had inferior MI and 21 (14%) had lateral MI. RV infarction was observed in 50 patients (34%) of the cohort. RV remodeling did not occur alone. It was observed in 51 patients (34.7%) and was associated with LV remodeling. A strong association between right and left ventricular remodeling was noted (p=0.027). RV involvement in AMI is not rare and is a good predictor of LV EF impairment at 6 months. LV and RV remodeling are strongly associated. LV infarct size and microvascular obstruction do not influence RV remodeling but have an important role in LV remodeling.

PP.08.24

Objective: Arterial hypertension phenotyping by plasma renin activity (PRA) may be a useful approach to improve BP control. Thus target organ damage evaluation is important in different types of arterial hypertension determined by PRA measurement. The aim of study was to compare left ventricular systolic function with speckle tracking technique in subjects with low-renin and renin-mediated hypertension Design and method: PRA (radioimmune assay) was measured in 72 hypertensive subjects (age 61,1 ± 7,6 years, 30 male). PRA < 0,65 ng/ml/h was classified as volume (V)-type hypertension, PRA > 0,65 ng/ml/h - as renin (R)-type. Longitudinal global systolic deformation (LGSD) was evaluated by 2-D echocardiography (normal < -18,6%) and compared in subjects with two types of hypertension. Multivariate regression analysis was applied to define determinants of LGSD. p < 0,05 was considered significant. Results: 42 (58%) subjects had V-type hypertension, 30 (42%) - R-type. Despite patients with V-type hypertension were older (respectively, 63,1 ± 9,1 vs 60,3 ± 6,4 years, p < 0,05) and had higher systolic and diastolic BP (162,6 ± 14,1/103,7 ± 11,5 vs 157,9 ± 17,1/95,0 ± 7,8 mmHg), respectively, p < 0,05). Left ventricular ejection fraction was similar in the two subgroups: 64,8 ± 5,9% in V-type, and 68,5 ± 7,0% in R-type. Despite of normal EF impairment of LGSD was found in 75% among all patients and was significantly higher in subjects with R-type hypertension than in V-type, respectively, 97% vs 40% (χ2 = 75,3; p < 0,001). Absolute LGSD values were, respectively, −16,6 ± 3,3 vs -17,9 ± 3,4% (p < 0,05). Multivariate regression analysis revealed independent association of PRA and LGSD (β = 1,94, p < 0,001). Conclusions: Evaluation of longitudinal global systolic deformation reveals systolic dysfunction in 75% hypertensive patients. Systolic function impairment is associated with renin-mediated arterial hypertension.
