Abstract

BACKGROUND: We previously reported that infants who developed autism spectrum disorder (ASD) had increased cerebrospinal fluid (CSF) in the subarachnoid space (i.e., extra-axial CSF) from 6 to 24 months of age. We attempted to confirm and extend this finding in a larger independent sample. METHODS: A longitudinal magnetic resonance imaging study of infants at risk for ASD was carried out on 343 infants, who underwent neuroimaging at 6, 12, and 24 months. Of these infants, 221 were at high risk for ASD because of an older sibling with ASD, and 122 were at low risk with no family history of ASD. A total of 47 infants were diagnosed with ASD at 24 months and were compared with 174 high-risk and 122 low-risk infants without ASD. RESULTS: Infants who developed ASD had significantly greater extra-axial CSF volume at 6 months compared with both comparison groups without ASD (18% greater than high-risk infants without ASD; Cohens d = 0.54). Extra-axial CSF volume remained elevated through 24 months (d = 0.46). Infants with more severe autism symptoms had an even greater volume of extra-axial CSF from 6 to 24 months (24% greater at 6 months, d = 0.70; 15% greater at 24 months, d = 0.70). Extra-axial CSF volume at 6 months predicted which high-risk infants would be diagnosed with ASD at 24 months with an overall accuracy of 69% and corresponding 66% sensitivity and 68% specificity, which was fully cross-validated in a separate sample. CONCLUSIONS: This study confirms and extends previous findings that increased extra-axial CSF is detectable at 6 months in high-risk infants who develop ASD. Future studies will address whether this anomaly is a contributing factor to the etiology of ASD or an early risk marker for ASD.

L., Pike, G. B., Fonov, V., Kostopoulos, P., Das, S., Gerig, G., Styner, M., and Gu, H.

Abstract

The present study investigated the relationship between infant temperament characteristics and autism spectrum disorder (ASD) risk status. Temperament was examined at 6, 12, and 24 months in 282 infants at high familial risk for ASD and 114 low-risk controls using the Infant Behavior Questionnaire-Revised and Early Childhood Behavior Questionnaire. Infants were divided into three groups at 24 months: High-Risk Positive--classified as ASD (HR Pos), High-Risk Negative (HR Neg), and Low-Risk Negative (LR Neg). At 6 and 12 months HR Pos infants exhibited lower Surgency and Regulatory Capacity than LR Neg infants. By 12 months they also demonstrated increased Negative Affect. Group differences remained, when early signs of ASD were controlled for, suggesting that temperament differences could be useful targets for understanding the development of ASD.

Abstract

Preschool-aged siblings of children with ASD are at high-risk (HR) for ASD and related challenges, but little is known about their emerging peer competence and friendships. Parents are the main providers of peer-relationship opportunities during preschool. Understanding parental challenges supporting early peer relationships is needed for optimal peer competence and friendships in children with ASD. We describe differences in peer relationships among three groups of preschool-aged children (15 HR-ASD, 53 HR-NonASD, 40 low-risk, LR), and examine parent support activities at home and arranging community-based peer activities. Children with ASD demonstrated precursors to poor peer competence and friendship outcomes. Parents in the HR group showed resilience in many areas, but providing peer opportunities for preschool-age children with ASD demanded significant adaptations.

Abstract

Gestures are an important social communication skill that infants and toddlers use to convey their thoughts, ideas, and intentions. Research suggests that early gesture use has important downstream impacts on developmental processes, such as language learning. However, autistic children are more likely to have challenges in their gestural development. The current study expands upon previous literature on the differences in gesture use between young autistic and non‐autistic toddlers by collecting data using a parent‐report questionnaire called the MCDI–Words and Gestures at three time points, 12, 18, and 24 months of age. Results (N = 467) showed that high‐likelihood infants who later met diagnostic criteria for ASD (n = 73 HL‐ASD) have attenuated gesture growth from 12 to 24 months for both deictic gestures and symbolic gestures when compared to high‐likelihood infants who later did not meet criteria for ASD (n = 249 HL‐Neg) and low‐likelihood infants who did not meet criteria for ASD (n = 145 LL‐Neg). Other social communicative skills, like play behaviors and imitation, were also found to be impacted in young autistic children when compared to their non‐autistic peers. Understanding early differences in social communication growth before a formal autism diagnosis can provide important insights for early intervention. Lay Summary: As infants learn to talk, they use gestures to communicate. In this study, we used a parent‐report questionnaire to look at the group level differences of gestures in the first 2 years of life by comparing infants who later developed autism to infants who did not develop autism. We found that infants who later developed autism have fewer gestures and a slower rate of gesture growth compared to infants who did not develop autism. Play behaviors and imitation skills were also impacted in young autistic children when compared to their non‐autistic peers. [ABSTRACT FROM AUTHOR]

Abstract

Item does not contain fulltext, Pathogenic variants in KMT5B, a lysine methyltransferase, are associated with global developmental delay, macrocephaly, autism, and congenital anomalies (OMIM# 617788). Given the relatively recent discovery of this disorder, it has not been fully characterized. Deep phenotyping of the largest (n = 43) patient cohort to date identified that hypotonia and congenital heart defects are prominent features that were previously not associated with this syndrome. Both missense variants and putative loss-of-function variants resulted in slow growth in patient-derived cell lines. KMT5B homozygous knockout mice were smaller in size than their wild-type littermates but did not have significantly smaller brains, suggesting relative macrocephaly, also noted as a prominent clinical feature. RNA sequencing of patient lymphoblasts and Kmt5b haploinsufficient mouse brains identified differentially expressed pathways associated with nervous system development and function including axon guidance signaling. Overall, we identified additional pathogenic variants and clinical features in KMT5B-related neurodevelopmental disorder and provide insights into the molecular mechanisms of the disorder using multiple model systems.

Abstract

Introduction: Stroke causes disability and pain, especially shoulder pain. Often, shoulder pain, has a not completely known mechanism and evolution.1,2 Objectives: Assess shoulder pain and its impact in upper limb function, in patients who had suffered a stroke within 6 months. Methods: Observational study. Included patients at discharge from an inpatient rehabilitation centre, from November 2019 until February 2020. Assessment was done using validated Portuguese versions of the Brief Pain Inventory (BPI) and Fugl Meyer Assessment Scale (FMAS). Results: Of 32 patients screened, 26 fulfilled the inclusion criteria, 7 were females (26,9 %), with mean age of 60,7±10 years. Mean values of BPI Severity and Interference were 3,2±1,6 and 2,4±1,8, respectively. The mean values of the FMAS Motor Function and Passive Articular Movement were 38,8±23,2 and 20,3±2,3, respectively. Analysing the association between both subscales of BPI and both Subscales of FMAS negative correlations were found to be statistically significant with a confidence interval of 95% but there was no correlation between BPI Severity and FMAS motor function. Six patients (23%) received a local injection for shoulder pain. Analysing both groups, BPI Severity and both subscales of FMAS showed a statistically significant difference (p values of 0,0083, 0,0031 and 0,0056, respectively) for a Wilcoxon/Kruskal-Wallis test with a confidence interval of 95%. Discussion/Conclusions: Patients with voluntary upper limb movements after a stroke tend to have less shoulder pain. Local injection was an effective intervention for shoulder pain. The greatest limitation of this study is the small sample size.

Abstract

Software-Defined Networking (SDN) é um paradigma de rede que permite a aplicação de novas técnicas de engenharia de tráfego através da separação do plano de controle do plano de encaminhamento. De forma a dar suporte às características dinâmicas do ambiente computacional (tais como, condições dinâmicas de tráfego e variedade protocolos de rede, mobilidade do usuário, heterogeneidade de dispositivos, entre outros), técnicas inovadoras de engenharia de tráfego devem ser propostas para lidar com aplicações sensíveis às variações de atraso, tais como videoconferência e voz sobre IP. Neste trabalho apresentamos o arcabouço Context-Aware Adaptive Routing Framework SDN (CAARF-SDN), uma solução para otimização do tráfego de redes, compatível com qualquer controlador SDN, através de uma abordagem dinâmica e proativa baseada em contexto. Neste trabalho, está aplicado a otimização de tráfego de voz abordando a mudança da prioridade do fluxo e a mudança de topologia, baseando a noção de contexto nas métricas de qualidade de serviço, experiência e dispositivo (QoE, QoS e QoD) demonstrando a otimização dos recursos de rede em cenários adversos.

Abstract

Using the Infant Behavior Questionnaire–Revised in a longitudinal sample of infant siblings of autistic children (HR; n = 427, 171 female, 83.4% White) and a comparison group of low‐risk controls (LR, n = 200, 86 female, 81.5% White), collected between 2007 and 2017, this study identified an invariant factor structure of temperament traits across groups at 6 and 12 months. Second, after partitioning the groups by familial risk and diagnostic outcome at 24 months, results reveal an endophenotypic pattern of Positive Emotionality at both 6 and 12 months, (HR‐autism spectrum disorder [ASD] < HR‐no‐ASD < LR). Third, increased 'Duration of Orienting' at 12 months was associated with lower scores on the 24‐month developmental outcomes in HR infants. These findings may augment efforts for early identification of ASD. [ABSTRACT FROM AUTHOR]

Abstract

Thin layers of MnSi, the first discovered host material of a skyrmion lattice, are epitaxially grown on Si(111) and their crystal properties are investigated by X-ray diffraction and transmission electron microscopy (TEM) measurements. Azimuthal φ-scans of asymmetric X-ray reflections reveal the formation of twinned domains with their unit cell rotated ±30° in plane with respect to the Si unit cell. The intensities of corresponding reflections indicate the same volume fractions for both domain types. Cross-sectional TEM confirms the presence of these domains and reveals a typical domain size of about 200 nm. [ABSTRACT FROM AUTHOR]

Abstract

Resting state functional magnetic resonance imaging (rs-fMRI) in infants enables important studies of functional brain organization early in human development. However, rs-fMRI in infants has universally been obtained during sleep to reduce participant motion artifact, raising the question of whether differences in functional organization between awake adults and sleeping infants that are commonly attributed to development may instead derive, at least in part, from sleep. This question is especially important as rs-fMRI differences in adult wake vs. sleep are well documented. To investigate this question, we compared functional connectivity and BOLD signal propagation patterns in 6, 12, and 24 month old sleeping infants with patterns in adult wakefulness and non-REM sleep. We find that important functional connectivity features seen during infant sleep closely resemble those seen during adult sleep, including reduced default mode network functional connectivity. However, we also find differences between infant and adult sleep, especially in thalamic BOLD signal propagation patterns. These findings highlight the importance of considering sleep state when drawing developmental inferences in infant rs-fMRI. Fil: Mitra, Anish.

Abstract

Background We previously reported that infants who developed autism spectrum disorder (ASD) had increased cerebrospinal fluid (CSF) in the subarachnoid space (i.e., extra-axial CSF) from 6 to 24 months of age. We attempted to confirm and extend this finding in a larger independent sample. Methods A longitudinal magnetic resonance imaging study of infants at risk for ASD was carried out on 343 infants, who underwent neuroimaging at 6, 12, and 24 months. Of these infants, 221 were at high risk for ASD because of an older sibling with ASD, and 122 were at low risk with no family history of ASD. A total of 47 infants were diagnosed with ASD at 24 months and were compared with 174 high-risk and 122 low-risk infants without ASD. Results Infants who developed ASD had significantly greater extra-axial CSF volume at 6 months compared with both comparison groups without ASD (18% greater than high-risk infants without ASD; Cohen's d = 0.54). Extra-axial CSF volume remained elevated through 24 months (d = 0.46). Infants with more severe autism symptoms had an even greater volume of extra-axial CSF from 6 to 24 months (24% greater at 6 months, d = 0.70; 15% greater at 24 months, d = 0.70). Extra-axial CSF volume at 6 months predicted which high-risk infants would be diagnosed with ASD at 24 months with an overall accuracy of 69% and corresponding 66% sensitivity and 68% specificity, which was fully cross-validated in a separate sample. Conclusions This study confirms and extends previous findings that increased extra-axial CSF is detectable at 6 months in high-risk infants who develop ASD. Future studies will address whether this anomaly is a contributing factor to the etiology of ASD or an early risk marker for ASD.

Abstract

Equipas interdisciplinares estão na base do sucesso de muitos trabalhos de investigação. Um exemplo disso é a colaboração da estatística com as ciências da saúde. Neste trabalho, recorrendo a testes não paramétricos e a modelos de regressão logística, foi possível contribuir para o conhecimento da não acuidade, da ecografia no diagnóstico de colecistite aguda na presença de pancreatite aguda. Deste modo, este estudo contribui para um melhor diagnóstico clínico que será determinante na terapêutica a adotar. info:eu-repo/semantics/publishedVersion
