RESUMO

To assess the effect of active and passive intra-interval recovery modes in time-efficient high-intensity interval training (HIT) on cardiorespiratory fitness, autonomic function, and endothelial function in sedentary middle-aged men.Participants (n = 62; age: 49.5 ± 5.8 y; BMI: 29.7 ± 3.7 kg·m-2) completed the assessments of cardiorespiratory fitness, flow-mediated dilation (FMD) and heart rate variability before being randomly allocated to control (CON; n = 14), moderate intensity continuous training (MICT; n = 15), HIT with passive (P-HIT; n-15), or active recovery (A-HIT; n = 15). Participants performed thrice weekly exercise sessions for 12 weeks. MICT completed 50-60 min of continuous cycling at 60-70% heart rate (HR) maximum. HIT completed 30-s work intervals (∼85% HR) interspaced with 2.5 min of active or passive recovery.All exercise modalities increased oxygen uptake (V̇O2) (MD: ≥ 3.1 ml·kg-1·min-1, 95%CI: 1.5-4.7 ml·kg-1·min-1; P < 0.001), power output (MD: ≥ 26 W, 95%CI: 15-37 W; P < 0.001) and cycle duration (MD: ≥ 62 s, 95%CI: 36-88 s; P < 0.001) at 85% HRM. Significant pre-to-post differences were observed among all exercise groups for FMD (MD: ≥ 3.4%, 95%CI: 0.3-6.5%; P < 0.05), while MICT and P-HIT significantly increased the standard deviation of all NN intervals (SDNN) pre-to-post intervention (MD: ≥ 7 ms, 2-13 ms; P ≤ 0.05).Time-efficient HIT elicits significant improvements in cardiorespiratory fitness, FMD and autonomic modulation following a thrice weekly 12-week exercise intervention among sedentary middle-aged men. Active recovery between successive high-intensity intervals provided no additional benefit among this deconditioned cohort.

RESUMO

BACKGROUND: A prior drug trial of cannabidiol for treatment-resistant epilepsy in patients with Sturge-Weber syndrome (SWS), a rare neurovascular condition, implicated improvements in neurological, quality of life (QOL), neuropsychologic, psychiatric, and motor outcomes. METHODS: Ten subjects with SWS brain involvement, controlled seizures, and cognitive impairments received study drug in this Johns Hopkins institutional review board-approved, open-label, prospective drug trial. Oral cannabidiol was taken for six months (dose ranged from 5 to 20 mg/kg/day). SWS neuroscore, port-wine birthmark score, QOL, and adverse events were recorded every four to 12 weeks. Neuropsychologic, psychiatric, and motor assessments were administered at baseline and six months' follow-up. Most evaluations were conducted virtually due to the coronavirus disease 2019 pandemic. RESULTS: Cannabidiol was generally well tolerated. Six subjects reported mild to moderate side effects related to study drug and continued on drug; one subject withdrew early due to moderate side effects. No seizures were reported. Significant improvements in SWS neuroscore, patient-reported QOL, anxiety and emotional regulation, and report of bimanual ability use were noted. Migraine QOL scores were high at baseline in these subjects, and remained high. Neuropsychologic and other QOL and motor outcomes remained stable, with some within-subject improvements noted. CONCLUSIONS: Further studies are needed to determine whether Epidiolex can improve quality of life and be beneficial for neurological, anxiety, and motor impairments in SWS independent of seizure control. Large multicentered studies are needed to extend these preliminary findings.

RESUMO

OBJECTIVE: This study examined test score equivalency between traditional in-person assessment and teletesting among youth diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD). METHOD: In all, 896 youth with ADHD, ages 5-21 years, were administered cognitive, academic achievement, and verbal fluency measures via either teletesting (n = 448) or traditional in-person assessment (n = 448). The teletesting and in-person groups were matched on age, sex, and insurance type (as a proxy for income). RESULTS: Results indicated no significant differences in test scores obtained via in-person and teletesting evaluations across all examined measures. CONCLUSION: Clinically referred youth with ADHD perform similarly on measures of cognitive functioning, academic achievement, and verbal fluency, regardless of whether these measures are administered in-person or via teletesting. While additional evidence for equivalent psychometric properties of neuropsychological instruments administered remotely is needed, this study offers support for the validity of remote administration among youth with ADHD.

RESUMO

The Physical and Neurological Examination of Subtle Signs (PANESS) is a brief neuromotor exam designed for use in children. This study examined the inter-rater reliability of PANESS scoring using video review in 23 typically developing youth, aged 10-18 years, who were either never-concussed or evaluated following clinical recovery from concussion. Moderate to excellent inter-rater reliability was identified across PANESS subscores and total score. The strongest inter-rater reliability was observed for the Timed Motor portion of the PANESS (ICCs >.90) suggesting that this section in particular may be a strong candidate for video-based scoring or telehealth administration.

RESUMO

Introduction: Sonographers in the Western New South Wales Local Health District (WNSWLHD) reported a musculoskeletal pain prevalence rate of 95%. Participatory ergonomics, where workers are consulted about improving work conditions, was utilised to identify work-related musculoskeletal disorder (WMSD) risks and potential solutions. The aim of this study was to compare the prevalence of WMSD in a cohort of sonographers before and after implementation of ergonomic changes that were driven by recommendations from a participatory ergonomics approach. Methods: This observational mixed methods study analysed the impact of participatory ergonomic-driven interventions on changes on musculoskeletal pain in a cohort of sonographers employed within the WNSWLHD. A retrospective analysis of 10 sonographer WMSD pain surveys over five sites was completed, along with semi-structured interviews regarding which interventions were perceived as useful, which interventions were not implemented and any barriers to implementation. Results: Installation of patient monitors, use of ergonomic scanning techniques and job rotation were perceived as responsible for decreased musculoskeletal pain. Taking lunch breaks and microbreaks, use of antifatigue mats and having two sonographers perform mobile exams were not fully implemented. No interventions were perceived as responsible for increased pain. Conclusion: This small study provides preliminary evidence that a participatory ergonomics approach facilitated identification of occupation and site-specific risks for WMSD in the WNSWLHD, allowing implementation of ergonomic changes to be tailored to the workplace, resulting in a safer work environment for sonographers.

RESUMO

The aim of this systematic review was to summarise the effects of ergonomics interventions on work-related upper limb musculoskeletal pain and dysfunction, and on productivity in sonographers, surgeons and dentists. A total of 31 studies were included. All studies reported effects on upper limb pain. Nine studies reported effects on dysfunction and only two studies reported effects on productivity. Moderately strong evidence in reducing upper limb pain was found for instigation of microbreaks into long duration surgical procedures, and the use of wider, lighter handles in dental instruments. Moderate evidence was also found for use of prismatic glasses and favourable positioning in reducing upper limb pain. Weak, inconsistent or no evidence was found for all other ergonomics interventions in reducing upper limb pain and dysfunction and increasing productivity. The lack of high quality research, particularly in sonographers and in the outcome of productivity, should be addressed. Practitioner summary: This systematic review investigates the effectiveness of ergonomics interventions on upper limb pain, dysfunction and productivity in sonographers, dentists and surgeons. Instigation of microbreaks during long duration procedures and the use of wider, lighter instrument handles were most effective in reducing upper limb work-related pain.

RESUMO

Objective: As the coronavirus pandemic extends across the globe, the impacts have been felt across domains of industry. Neuropsychology services are no exception. Methods for neuropsychological assessments, which typically require an in-person visit, must be modified in order to adhere to social distancing and isolation standards enacted in an effort to slow the pandemic. How can providers continue to meet the needs of patients referred for neuropsychology evaluations, while respecting federal and state guidelines for safety and ethical mandates? We offer a novel, tiered model of care, successfully implemented in response to mandated social distancing, in a large, pediatric neuropsychology program.Method: We describe the considerations and challenges to be addressed in transitioning a large neuropsychology department to a new model of care, including triaging referrals, developing -or rediscovering - types of services to meet the needs of a virtual patient population, and helping patients, parents, and providers to adjust to these new models.Conclusions: Lessons learned as a function of rapid changes in care models have implications for the field of neuropsychology as a whole as well as for future flexibility in meeting the needs of pediatric patients and their families.

RESUMO

Motor deficits persisting into childhood (>7 years) are associated with increased executive and cognitive dysfunction, likely due to parallel neural circuitry. This study assessed the longitudinal trajectory of motor deficits in preschool children with ADHD, compared to typically developing (TD) children, in order to identify individuals at risk for anomalous neurological development. Participants included 47 children (21 ADHD, 26 TD) ages 4-7 years who participated in three visits (V1, V2, V3), each one year apart (V1=48-71 months, V2=60-83 months, V3=72-95 months). Motor variables assessed included speed (finger tapping and sequencing), total overflow, and axial movements from the Revised Physical and Neurological Examination for Subtle Signs (PANESS). Effects for group, visit, and group-by-visit interaction were examined. There were significant effects for group (favoring TD) for finger tapping speed and total axial movements, visit (performance improving with age for all 4 variables), and a significant group-by-visit interaction for finger tapping speed. Motor speed (repetitive finger tapping) and quality of axial movements are sensitive markers of anomalous motor development associated with ADHD in children as young as 4 years. Conversely, motor overflow and finger sequencing speed may be less sensitive in preschool, due to ongoing wide variations in attainment of these milestones.

RESUMO

Cognitive neuroscience models suggest both reward valuation and cognitive control contribute to reward-based decision-making. The current study examined the relationship between cognitive control and delay discounting (i.e., choosing smaller, immediate over larger, delayed rewards) in a large sample of boys and girls diagnosed with attention-deficit/hyperactivity disorder (ADHD; N = 95) and typically developing control children (TD; N = 59). Specifically, we examined performance on multiple measures of cognitive control (i.e., Go/No-Go task, Stop Signal task, and Spatial Span task) and delay discounting (i.e., Classic Delay Discounting and Real-Time Delay Discounting tasks), as well as the relationship between these measures. Results indicated that sex moderated the effects of group on task performance. Specifically, girls with ADHD, but not boys with the disorder, exhibited atypical delay discounting of real-time rewards. Results from correlational analyses indicated that delay discounting and cognitive control were not significantly correlated in the overall sample. Multiple regression analyses demonstrated that among girls with ADHD poorer spatial working memory and inhibitory control predicted greater real-time discounting. Collectively, findings provide support for distinct patterns of cognitive control and delay discounting among school-aged girls and boys with ADHD. Additionally, findings suggest that among girls with ADHD, those who exhibit relatively poor working memory and inhibitory control might be a particularly vulnerable subgroup with the greatest propensity to exhibit maladaptive decision-making.

RESUMO

BACKGROUND: Imitation, which is impaired in children with autism spectrum disorder (ASD) and critically depends on the integration of visual input with motor output, likely impacts both motor and social skill acquisition in children with ASD; however, it is unclear what brain mechanisms contribute to this impairment. Children with ASD also exhibit what appears to be an ASD-specific bias against using visual feedback during motor learning. Does the temporal congruity of intrinsic activity, or functional connectivity, between motor and visual brain regions contribute to ASD-associated deficits in imitation, motor, and social skills? METHODS: We acquired resting-state functional magnetic resonance imaging scans from 100 8- to 12-year-old children (50 ASD). Group independent component analysis was used to estimate functional connectivity between visual and motor systems. Brain-behavior relationships were assessed by regressing functional connectivity measures with social deficit severity, imitation, and gesture performance scores. RESULTS: We observed increased intrinsic asynchrony between visual and motor systems in children with ASD and replicated this finding in an independent sample from the Autism Brain Imaging Data Exchange. Moreover, children with more out-of-sync intrinsic visual-motor activity displayed more severe autistic traits, while children with greater intrinsic visual-motor synchrony were better imitators. CONCLUSIONS: Our twice replicated findings confirm that visual-motor functional connectivity is disrupted in ASD. Furthermore, the observed temporal incongruity between visual and motor systems, which may reflect diminished integration of visual consequences with motor output, was predictive of the severity of social deficits and may contribute to impaired social-communicative skill development in children with ASD.

RESUMO

Congenital Epulis (CE) is a rare, benign tumour of the mucosa of the mouth in a neonate. It presents as an intraoral tumour and is rarely diagnosed prenatally. Complications include neonatal airway compromise, difficulty feeding and aesthetic considerations. Ultrasound is useful in aiding decisions regarding site, age, method of delivery and preparing parents and staff for the appearances of the tumour at birth. We present a case where CE was identified at 35 weeks gestational age during a routine third trimester prenatal ultrasound. The patient was scanned at a rural centre, referred to a tertiary institution for follow up and delivered at a specialist perinatal surgical centre, in preparation for neonatal surgery. The outcome was excellent and this case is a good example of multi-centre cooperation.
