Modulation effects of the intact motor skills on the relationship between social skills and motion perceptions in children with autism spectrum disorder : A pilot study

Background: An individual with autism spectrum disorder (ASD) has social skill, motor skill, and motion perception deficits. However, the relationship among them was not clarified. Therefore, this study aimed to evaluate the effects of motor skills on social skills and motion perception.Methods: Five typically developed children and fourteen children with ASD participated in our study. The N200 component, a brain activity indicating motion perception, was induced in mid-temporal (MT/V5) brain area by watching a random dot kine-matograph, and was recorded using a scalp electroencephalogram. Furthermore, the social responsiveness scale (SRS) indicating the social skill deficit, the developmental coordination disorder questionnaire (DCDQ) estimating the developmental coordination disorder (DCD), and the movement assessment battery for children second edition (MABC-2) indicating motor skills were recorded in the children with ASD. A hierarchical multiple regression analysis was conducted to examine the modulation effects of motor skills on the relationship between social skills and motion perception. The dependent variable was the N200 latency, and the inde-pendent variables were SRS, MABC-2, and combined MABC-2 and SRS.Results: The N200 latency was more delayed in children with ASD relative that in typically developed children. Intact balance ability modulated the relationship between social skills and N200 latency in children with ASD. Within the high balance ability, when the social skills worsened, the N200 latency was shortened. Conclusions: This is the first report that intact motor skills could modulate the relationship between social skills and motion perception.(c) 2022 The Japanese Society of Child Neurology Published by Elsevier B.V.

Effects of posture regulation on mood states, heart rate and test performance in children

This experiment aimed to investigate the effects of seated posture regulation on children’s psychological and physiological state and test performance. Thirty-eight boys (mean age: 12.3 ± 0.53 years) participated in both upright and normal posture conditions in a within-participants design. Participants completed a two-dimensional mood scale to measure psychological mood states and performed three tests (calculation, listening comprehension and word memory). Heart rate, as an index of physiological arousal state, was measured. Upright posture resulted in greater vitality and pleasure, as well as increased heart rate, compared with normal posture. Upright posture also led to significantly higher scores for calculation and listening comprehension tests. Moreover, increases in vitality level positively influenced increases in calculation and listening comprehension test scores. This study suggests that adopting an upright posture results in maintaining a positive psychological state and improving test performance of children

Clinical profile of reading ability and reading and writing achievement of children with borderline full-scale intellectual quotient : a prospective study

Background Poor reading ability is one of the common causes of low academic performance. In previous studies, children with dyslexia were found to demonstrate poor academic achievement due to poor reading ability. However, the relationship between academic achievement and reading ability in children with a borderline full-scale intellectual quotient (FSIQ) is unknown. This study aimed to clarify the clinical characteristics of children with borderline FSIQ and poor reading ability, and differentiate these characteristics from those of children with higher FSIQ and poor reading ability. Methods A total of 126 children (aged 6-15 years) identified as having low academic performance were enrolled. The reading ability of children was assessed through their performance on the hiragana (Japanese syllabary) reading task, while their reading and writing achievement was assessed through their reading and writing score on the Kaufman Assessment Battery for Children, Second Edition. Children were categorized into two groups based on their FSIQ score (FSIQ > 85 and 85 >= FSIQ >= 70). Reading ability in children was evaluated by referring to the linear relationship between FSIQ and the standard deviation value of reading tasks in typically developing children. A one-way analysis of variance (ANOVA) was performed to examine clinical characteristics between higher and lower FSIQ groups. Associations between reading and writing achievement, reading ability, and ages of children were assessed using Pearson's product-moment correlation coefficients for the higher and lower FSIQ groups. Results Poorer reading and writing achievement was associated with poorer reading ability in the higher FSIQ group. Conversely, poorer reading and writing achievement and poor reading ability were associated with older age in the lower FSIQ group. Conclusions Poor reading and writing achievement were associated with older age, not with poor reading ability in the lower FSIQ group. Children with lower FSIQ need appropriate educational interventions based on independent assessments to further their academic achievement and reading ability. Moreover, they need more frequent evaluations of their academic achievement than do children with higher FSIQ and poor reading ability since they are more likely to be at a lower academic achievement level at an older age.Peer reviewe

Exploring autistic-like traits relating to empathic attitude and psychological distress in hospital pharmacists

BACKGROUND: Pharmacists are expected to play a key role in modern cancer care. Research suggests that an empathic approach and attitude in medical staff improves the quality of patient care. An empathic attitude and psychological distress are thought to be associated with autistic-like traits, but little is known about such traits. OBJECTIVE: In this study, we aimed to clarify the associations among autistic-like traits, empathic attitude in a medical context, and psychological health in hospital pharmacists. SETTING: Eligibility criteria for inclusion were certified pharmacists working at hospitals for patient care who returned their questionnaires. METHOD: Eight hundred and twenty-three hospital pharmacists completed a number of self-administered questionnaires anonymously by mail. MAIN OUTCOME MEASURES: Scores were obtained on the Autism-Spectrum Quotient, the Jefferson Scale of Empathy, the General Health Questionnaire-12, and subscales of the Interpersonal Reactivity Index (Perspective Taking, IRI-Empathic Concern, IRIPersonal Distress). We performed correlation and mediation analyses to confirm that the empathy and general health questionnaires were associated with autism-spectrum quotient scores, and with each IRI subscale. RESULTS: Complete responses were obtained from 379 pharmacists comprising 151 males (39.8 %) with a mean age of 37.7 ± 10.8 years (missing data, n = 13) and a median of 11 years after qualification as a pharmacist. Autism-Spectrum Quotient scores were inversely correlated with empathy (r = -0.22, p < 0.001) and positively correlated with general health scores (r = 0.40, p < 0.001). In the models with mediation, the inverse correlation between autism-spectrum quotient and empathy scores was mediated indirectly by IRI-Perspective Taking and IRI-Empathic Concern, and the positive correlation between autism-spectrum quotient and general health was mediated indirectly by IRI-Personal Distress. There were also direct effects, with significant effects of autism-spectrum quotient on empathy and general health scores. CONCLUSION: Our findings suggest that autistic-like traits affect both empathic attitude in a medical context and the psychological health of pharmacists. We recommend that to improve empathy in those with high levels of autistic-like traits, we may need to develop specialized interventions, such as improving communication skills training

EDA-BASED ESTIMATION OF VISUAL ATTENTION BY OBSERVATION OF EYE BLINK FREQUENCY

This paper describes the relationship between visual attention and eye blink frequency. In an experiment, we prompted the activation of a subject's visual attention and examined the influence of visual attention (as measured using electrodermal activity (EDA), which is meaningfully correlated with visual attention) on the subject's eye blink frequency. Experimental results show that engagement of visual attention decreased eye blink frequency and that when visual attention was not activated, eye blink frequency increased. Knowledge of this relationship provides a technique using EDA to objectively determining a subject's visual attention status

Development of a preoperative prediction model for new-onset diabetes mellitus after partial pancreatectomy

ABSTRACT: Pancreatectomy is an invasive surgery that is sometimes associated with complications. New-onset diabetes mellitus sometimes develops after partial pancreatectomy and severely affects the patient's quality of life. This study aimed to develop a preoperative prediction model of new-onset diabetes mellitus after partial pancreatectomy, which will help patients and surgeons to achieve more easily better common decisions on regarding whether to perform partial pancreatectomy. This retrospective cohort study analyzed medical records of patients who underwent partial pancreatectomy (total pancreatectomy excluded) from April 1, 2008, to February 28, 2016, which were available in the database provided by Medical Data Vision Co., Ltd. (Tokyo, Japan). The predictors were preoperative age, body mass index, hemoglobin A1c level, blood glucose level, and indication for partial pancreatectomy. The outcome was the development of new-onset diabetes mellitus at 1 to 12 months after partial pancreatectomy. We used a logistic regression model and calculated the scores of each predictor. To determine test performance, we assessed discrimination ability using the receiver operating characteristic curve and calibration with a calibration plot and the Hosmer-Lemeshow test. We also performed internal validation using the bootstrap method. Of 681 patients, 125 (18.4%) had new-onset diabetes mellitus after partial pancreatectomy. The developed prediction model had a possible range of 0 to 46 points. The median score was 13, and the interquartile range was 9 to 22. The C-statistics of the receiver operating characteristic curve on the score to predict the outcome was .70 (95% confidence interval [CI], .65-.75). Regarding the test performance, the Hosmer-Lemeshow test was not significant (P = .17), and calibration was good. In the bootstrapped cohorts, the C-statistics was .69 (95% CI, .62-.76). We developed a preoperative prediction model for new-onset diabetes mellitus after partial pancreatectomy. This would provide important information for surgeons and patients when deciding whether to perform partial pancreatectomy

Reduced Nogo-P3 in adults with developmental coordination disorder (DCD)

Nogo-N2 is associated with the premotor cognitive process that precedes motor response (e.g., conflict monitoring), whereas Nogo-P3 is related to the inhibition of the actual motor response. We examined the influence of motor clumsiness of developmental coordination disorder (DCD) on components of the event-related potential in a Go/Nogo task. Participants were healthy adults (N = 81) that were classified into control and DCD groups based on the Movement Assessment Battery for Children Second Edition. We manipulated the difficulty in stopping a response by varying the frequency of Nogo stimuli in a response task into rare (20%) and frequent (80%) conditions, and Nogo-N2 and Nogo-P3 were calculated from electroencephalograms (EEGs) during the Go/Nogo tasks. The commission error rate in the rare condition was significantly higher in the DCD group than in the control group, indicating that motor clumsiness decreases task performance. There were no differences in Nogo-N2 between DCD and control groups. However, Nogo-P3 in the rare condition was reduced in the DCD group compared to the control group. These results suggest that the influence of motor clumsiness is limited to the cognitive process after the initiation of the actual motor response.Peer reviewe

Analysis of Surgical Outcomes of Diverticular Disease of the Colon

We analyzed retrospectively the surgical outcomes of diverticular diseases of the colon at the surgical division of Fukuyama Medical Center. Data were collected from 39 patients who underwent surgery for diverticular disease at Fukuyama Medical Center. Thirty-nine patients were admitted between 2005 and 2010. The mean age of the 39 patients was 63.6 years. The collected data included patient demographics, patient history, type of surgery and complications. Patients were divided into 2 groups, Elective vs. Emergent group, right vs. left colon group and laparotomy vs. laparoscopic approach. Multivariate analysis of the logistic model of morbidity revealed a significantly higher rate in the left colon and the Cox proportional hazards model clearly showed fewer postoperative hospital days with the laparoscopic approach. Surgical procedures should be decided in reference to the particular clinical and pathological features of diverticular disease to gain an acceptable morbidity and mortality rates

DNA Lesions Induced by Replication Stress Trigger Mitotic Aberration and Tetraploidy Development

During tumorigenesis, cells acquire immortality in association with the development of genomic instability. However, it is still elusive how genomic instability spontaneously generates during the process of tumorigenesis. Here, we show that precancerous DNA lesions induced by oncogene acceleration, which induce situations identical to the initial stages of cancer development, trigger tetraploidy/aneuploidy generation in association with mitotic aberration. Although oncogene acceleration primarily induces DNA replication stress and the resulting lesions in the S phase, these lesions are carried over into the M phase and cause cytokinesis failure and genomic instability. Unlike directly induced DNA double-strand breaks, DNA replication stress-associated lesions are cryptogenic and pass through cell-cycle checkpoints due to limited and ineffective activation of checkpoint factors. Furthermore, since damaged M-phase cells still progress in mitotic steps, these cells result in chromosomal mis-segregation, cytokinesis failure and the resulting tetraploidy generation. Thus, our results reveal a process of genomic instability generation triggered by precancerous DNA replication stress
