Predictors of maternal stress in pre-school and school-aged children with autism

Background: Mothers of children with autism experience high levels of stress. However, little is known about whether maternal stressors differ across children of different ages.

Method: This study investigated stressors in mothers of 29 pre-school-aged and 27 school-aged children with autism. Correlation and regression analyses were used to determine if maternal stressors differed between the two age groups.

Results: Findings revealed no difference in maternal stress levels across the two age groups; however, stressors for each age group were different. Stressors in the school-aged group were related to repetitive behaviours, sensory sensitivities, and problematic behaviours, while stressors in the pre-school-aged group were mainly related to adaptive behaviours.

Conclusions: These findings are informative for practitioners and highlight the need for tailored supports and therapies for mothers of children with autism of different ages.     

Using photographs to explore self-understanding in adolescent boys with an autism spectrum condition

Background: Research evidence suggests that self-understanding is likely to be limited in individuals with autism.

Method: Photo-elicitation interview was used to explore self-understanding in five adolescent boys diagnosed with an autism spectrum condition.

Results: An interpretative phenomenological analysis yielded three superordinate themes: self in action, self extended in time and self in relation to others. These themes captured how participants understood themselves in terms of their actions and abilities, in the context of their past and future and in relation to others.

Implications: The findings suggested that self-understanding is informed by relationships with parents, self-other comparisons and by reflecting on past and future selves, as well as on activities engaged in. Photo-elicitation was effective in engaging participants with the research process.     

Effect of activity-based mirror therapy on lower limb motor-recovery and gait in stroke: A randomised controlled trial

Objective: To determine the effect of activity-based mirror therapy (MT) on motor recovery and gait in chronic poststroke hemiparetic subjects.

Design: A randomised, controlled, assessor-blinded trial.

Setting: Rehabilitation institute.

Participants: Thirty-six chronic poststroke (15.89?±?9.01 months) hemiparetic subjects (age: 46.44?±?7.89 years, 30 men and functional ambulation classification of median level 3).

Interventions: Activity-based MT comprised movements such as ball-rolling, rocker-board, and pedalling. The activities were provided on the less-affected side in front of the mirror while hiding the affected limb. The movement of the less-affected lower limb was projected as over the affected limb. Conventional motor therapy based on neurophysiological approaches was also provided to the experimental group. The control group received only conventional management.

Main outcome measures: Brunnstrom recovery stages (BRS), Fugl-Meyer assessment lower extremity (FMA-LE), Rivermead visual gait assessment (RVGA), and 10-metre walk test (10-MWT).

Results: Postintervention, the experimental group exhibited significant and favourable changes for FMA-LE (mean difference?=?3.29, 95% CI?=?1.23–5.35, p?=?.003) and RVGA (mean difference?=?5.41, 95% CI?=?1.12–9.71, p?=?.015) in comparison to the control group. No considerable changes were observed on 10-MWT.

Conclusions: Activity-based MT facilitates motor recovery of the lower limb as well as reduces gait deviations among chronic poststroke hemiparetic subjects.     

Exploring dimensions of social support and resilience when providing care at the end of life: a qualitative study

Background: Research shows that formal and informal social support can facilitate resilience in carers. There is a paucity of research exploring social support and resilience amongst recently bereaved informal carers.

Aim: To examine how the presence or absence of distinct dimensions of social support facilitate or hinder resilience in recently bereaved informal carers.

Participants: 44 bereaved carers, who had been identified by GP as ‘main carer’ of someone recently deceased (3–12 months), aged between 38 and 87 years old (mean= 67).

Methods: Thematic analysis then the Ecological Framework of Resilience as an organisational tool to develop overarching themes in the data. We used the Sherbourne and Stewart model to identify social support that was lacking as well as social support that was present.

Results: A range of social support types were identified. There was an emphasis on the importance of relationships with both health professionals and family members, including the care recipient. However, social support was not necessary for resilience if the participant had other resources.

Conclusions: Social support for carers providing end of life care is almost exclusively based around end of life care ‘work’. In comparison to other research our study suggests that relationships with family and health professionals are paramount. Multidimensional support is needed for carers to enhance their resilience.     

Differences in Developmental Concerns of Young Children with Autism Spectrum Disorder Across Racial/Ethnic Groups

Purpose: Parents/caregivers of children with autism spectrum disorder (ASD) have varying types of initial concerns regarding their child’s development, which may be culturally bound to parents’ perceptions of their child’s development. This study investigated differences in the types of initial developmental concerns reported by parents or caregivers of different racial/ethnic groups with children in an early intervention program.

Method: This study examined the frequency of endorsement of different types of concerns in African American, Caucasian, and Hispanic families.

Results: No significant differences between racial/ethnic groups were found in the endorsement of concerns related to communication, language/speech, motor, problem behavior, sensory, feeding, prematurity, attention, adaptive functioning, and medical conditions. Racial/ethnic groups differed significantly in their endorsement for social concerns.

Conclusion: Racial/ethnic group differences were confirmed regarding initial developmental concerns related to social behavior, which may be due to cultural beliefs. The implications of these findings on early identification are discussed.     

French translation and validation of a fragile X syndrome screening checklist

Background: Fragile X syndrome (FXS) is the most common cause of inherited intellectual disability among men. This syndrome is frequently underdiagnosed in adults. The aim of this study was to develop and validate a French translation of the screening checklist Fragiele-X screeningslijst.

Method: The validation sample for the translated checklist included 22 pairs of men between the ages of 18 and 52, matched by age and degree of intellectual impairment.

Results: The translated checklist achieved coefficients of 0.92 for internal consistency, 0.90 for test-retest reliability and 0.65 for inter-rater reliability. These psychometric properties are commensurate with those of the original checklist.

Conclusion: Therefore, the translated checklist developed in this study can be considered a valid screening instrument for the detection of FXS in men with intellectual disabilities.

Abbreviations: FXS: fragile X syndrome; FMR1: fragile X mental retardation 1 (gene)     

Pharmacogenetics and levodopa induced motor complications

Aim: L-dopa remains the most effective symptomatic therapy for Parkinson's disease (PD) but unfortunately, its chronic use is often associated with motor complications. This review highlights the importance of pharmacogenetics in an individualised PD therapeutic approach.

Material and Methods: review of the literature was done.

Results: PD patients show remarkable heterogeneity in their response to L-dopa and this profound interindividual heterogeneity suggests that there is a genetic predisposition.

Conclusions: The impact of the genetic makeup of every individual on PD treatment appears to be of great importance in order to achieve not only the optimum therapeutic effect, but also with minimal side effects.     

A how-to guide to aphasia services: celebrating Professor Linda Worrall’s contribution to the field

Background: This article recognises Professor Linda Worrall’s contribution to aphasiology and discusses research themes which have grown from her work.

Aims: To review, summarise, and discuss literature relating to four themes which have emerged from the work of Professor Worrall: (1) Research capacity building; (2) Implementation of research evidence in clinical practice; (3) Meaningful outcome measurement; and (4) Improvement of psychological and emotional outcomes.

Main contribution: A review of the literature, with examples of practical applications.

Conclusions: The work of Professor Worrall has greatly influenced the field of aphasia; her legacy is the research capacity she has built in Australia and around the world.     

A comparison of WISC-IV and WISC-V verbal comprehension index scores for children with autism spectrum disorder

Objectives: This study aimed to explore changes in verbal comprehension subtest and index scores from Wechsler Intelligence Scale for Children, fourth edition (WISC)-IV to WISC-V for individuals with autism spectrum disorder (ASD), as the test revision dropped the subtest that has proven to be most challenging for those with ASD (i.e. Comprehension).

Methods: In all, 48 children with ASD who had been assessed with WISC-IV and re-evaluated with WISC-V were included in this study. Paired samples t-tests were used to examine changes in scores between administrations.

Results: Results indicated that changes in subtest scores were minimal although a statistically significant index score change occurred.

Discussion: These data suggest that administering additional measures of verbal intellect to individuals with ASD (i.e. beyond the two core verbal comprehension subtests of WISC-V) is critical for capturing the totality of their strengths and weaknesses, to effectively inform treatment planning.     

Estimation of skeletal muscle mass in patients with spinocerebellar ataxia type 3 and 10

Background: Neurodegenerative diseases may progress to a level in which patients present spontaneous weight loss, resulting in increased falls and functional disabilities when the disease is associated with muscle mass depletion.

Objective: Evaluate the muscle compartment in patients presenting spinocerebellar ataxia (SCA) type 3 and 10.

Methods: Forty-six patients presenting SCA type 3 and 10 were assessed and 76 volunteers were selected to the control group. In order to evaluate the muscle compartment, muscle mass anthropometric measurements were assessed and total skeletal muscle mass calculated through a predictive equation.

Results: Women with SCA3 presented greater weight loss and muscle mass reduction compared to those with SCA10 and the control group. Among the predictive measurements, calf muscle circumference showed a more significant correlation with total skeletal muscle mass (p = 0.718).

Conclusion: Patients presenting both types of ataxia did not show severe depletion in their nutritional status; however, those with SCA3 displayed greater weight loss and muscle mass reduction compared to the SCA10 group.     

Choosing among second-generation antidepressant treatments for depressed patients with cardiac diseases

Objectives: The present paper aimed to assist physicians in the accurate choice among second-generation agents (SGAs) for patients with cardiovascular disease (CVD).

Methods: We reviewed the published pharmacokinetic (PK) and pharmacodynamic (PD) clinical data that report potential -or absence of- drug interactions between second-generation agents (SGAs) and CVD drugs most commonly used in cardiology, including antiplatelet drugs and anticoagulants, statins, beta-blockers, angiotensin-converting enzyme inhibitors, calcium channel blockers, diuretics and the antiarrhythmic drugs amiodarone and digoxin.

We also reviewed the cardiovascular safety profile that has been published for each class of SGAs and side effects reported by patients with CVD.

Results: Most relevant PK/PD data about SGAs and CVD drugs are based on small studies or detailed case reports. In many cases, the drug interactions are at most assessed in healthy volunteers so that the clinical relevance of findings needs further investigation in patients with CVD. Case reports of serious, sometimes fatal reactions due to concomitant administration of certain drugs require careful consideration.

The major cardiac side effects of SGAs include HR increase, postural hypotension and slight prolongation of the intraventricular conduction time and QT interval. On normal dosage of antidepressants, both advanced heart block and ventricular arrhythmias could occur in patients with severe heart disease, together with clinically important loss of myocardial contractile force.

Conclusions: Data reported in the present review should help physicians about their decision-making processes that govern SGAs use in CVD patients.     

Assessment and Treatment of Problem Behavior Maintained by Termination of Interruptions

Purpose: Previous research has identified termination of interruptions to repetitive behaviour as a reinforcer capable of maintaining problem behaviour. Effective treatments have included functional communication training and multiple schedules of reinforcement.

Methods: In the present study, a functional analysis determined that the aggression of an eight-year-old boy with autism spectrum disorder was maintained by termination of interruptions of repetitive behaviour. An intervention was implemented consisting of differential reinforcement of other behaviour and response cost.

Results: The intervention produced and maintained a reduction in aggression and increased tolerance for interruptions of systematically increasing durations.

Conclusions: This case study demonstrates an alternative approach to the treatment of problem behaviours such as aggression maintained by termination of repetitive behaviour that includes teaching the individual to tolerate interruption of repetitive behavior.     

A Note on the “One Case per Stagger Position” Character of Common Multiple-Baseline Intervention Designs

Purpose: To overcome the constraint of common multiple-baseline designs that only one case per stagger position is permitted.

Methods: Three alternative strategies for assigning more than one case to each stagger position are examined.

Results: The three recommended strategies achieve the objective while maintaining the study’s internal and statistical-conclusion validities.

Conclusions: ExPRT, a freely available Excel-based randomization-test package, can be used to assist in both the design and statistical analysis associated with each of the strategies.     

Differences in sleep patterns,sleepiness, and physical activity levels between young adults with autism spectrum disorder and typically developing controls

Objective: To investigate the differences in sleep, sleepiness, and physical activity (PA) between young adults with autism spectrum disorder (ASD) and typically developing controls (TDC).

Method: Actigraphic data and questionnaires on sleep, sleepiness, and PA were compared between fifteen adults with ASD (ADOS range 7–19; ages 22.8 ± 4.5 years) and TDC.

Results: In comparison to the TDC group, the ASD group slept longer on average per night but took longer to fall asleep. In relationship to PA levels, the objective PA levels were lower in the ASD group than the TDC group. Fewer wake minutes during the sleep period in the ASD sample were associated with more PA the following day.

Conclusion: The findings support previous research that demonstrates differences in sleep parameters and PA between ASD and TDC. Interventions aimed at increasing PA in an ASD population may be beneficial for improved sleep.     

Perspectives of carers of people with intellectual disability accessing general practice: “I’d travel to the ends of the earth for the right person”⁣

Background: Informal carers often play an integral role in the lives of people with intellectual disability (ID) residing in the community. In this study, we explored the extent to which carers of people with ID believe that the health care needs of the person they care for are being accommodated by general practice.

Method: Semi-structured interviews were conducted with 25 informal carers to people with ID living in Australia.

Results: Carers of people with ID report that they experience considerable barriers to accessing general practice care on behalf of the people they care for.

Conclusions: Given the ever-increasing number of people with ID now living in the community and their vulnerability to health problems, it is imperative that future research focuses on the development of strategies to overcome the barriers identified in this study.     

Acute aseptic meningitis during isotretinoin treatment for nodular acne solely presenting with headache: case report and brief review of the literature

Purpose/aim: We describe, in detail, the first case of isotretinoin-induced aseptic meningitis. A brief summary of the literature on drug-induced aseptic meningitis (DIAM) is also presented.

Materials and methods: A 20-year old female patient with probable (Naranjo adverse reaction probability score of 7) DIAM during treatment with isotretinoin therapy for nodular acne solely, presenting with headache. Pseudotumor cerebri was appropriately ruled-out.

Results: Summary of data altogether lead us suggest that isotretinoin triggered DIAM, possible due to a delayed hypersensitivity mechanism type III or IV.

Conclusion: We highlight a quite uncommon cause of DIAM that may be increasing in frequency due to the current increasing use of isotretinoin against nodular acne.     

Utility of the Taiwan version of the Screening Tool for Autism in Two-Year-Olds to detect autism in children aged three years

Background: The Taiwan version of the Screening Tool for Autism in Two-Year-Olds (T-STAT) had been developed for identifying autism disorder (AD) in children aged 24–35 months. Two studies were performed to elucidate its utility for AD in children aged 36–48 months.

Method: In Study 1, the receiver operating characteristics were utilised to select a cutoff score for the T-STAT with 34 children with AD and with developmental delay (DD). In study 2, 147 children with AD, DD, and pervasive developmental disorder-not otherwise specified (PDD-NOS) were participated for validation.

Results: In study 1, the results indicated that a cutoff of 1.25 would yield high sensitivity and specificity. In study 2, the concurrent agreements between T-STAT risk and clinical diagnosis were high for children with AD and DD, but not PDD-NOS.

Conclusions: The results showed that T-STAT was a promising Level 2 screening tool for AD in children aged three years.     

Long-term cardiovascular safety of psychostimulants in children with attention deficit hyperactivity disorder

Objective: Side effects are a concern during psychostimulant treatment. Unfortunately, many previous studies only investigated short-term effects of psychostimulants in laboratory settings which lack clinical daily routines.

Methods: We examined 1042 patient records of patients with attention deficit hyperactivity disorder (ADHD) who were referred to a pediatric-psychiatry practice over 12?years. Data analysis was based on 466 children with ADHD who were newly treated with psychostimulants and who were not in treatment for elevated blood pressure. We analysed blood pressure percentiles, heart rate and BMI percentiles.

Results: There was a decrease in systolic and diastolic blood pressure percentiles. Heart rate was not affected. BMI slightly declined in girls.

Conclusions: In general psychostimulants were safe. To further elucidate negative effects of psychostimulants, long-term controlled and randomized studies in naturalistic settings are of interest.     

An international survey of obesity and underweight in youth and adults with intellectual disabilities

Background: Increased levels of obesity have been reported for people with intellectual disability based on data mostly gathered in high income countries. Likewise few studies internationally have focussed on underweight in this population.

Method: Data on obesity and underweight were analysed from nearly 86,500 youth and adults with intellectual disabilities drawn from 178 countries attending Special Olympic events.

Results: Binary logistic regressions identified higher levels of obesity for athletes in high income countries – especially in North America – and for females and for adults aged 40 years and over; and for youth aged 8 to 10 years. Rates of underweight were higher for younger adults in low income countries of Asia-Pacific, and highest for males aged 11-13 from lower-middle income countries of Africa.

Conclusions: Contrasting intervention strategies are needed globally to enable people with intellectual disabilities to achieve healthy weight.     

A review on the treatment of sporadic inclusion body myositis with Bimagrumab and Alemtuzumab

Background: Sporadic inclusion body myositis is the most common inflammatory myopathy over the age of 50. The aetiopathogenesis of the disease remains unclear and to the day there is no effective treatment.

Objectives: The aim of the present review is to present the latest data on the new insights and developments in the treatment of sporadic inclusion body myositis, focusing on Bimagrumab and Alemtuzumab.

Methods: For the purpose of the review we searched multiple internet databases in order to find the most recent studies and clinical trials on the safety, tolerability and efficacy of Bimagrumab and Alemtuzumab in sporadic inclusion body myositis.

Results: We found four trials on Bimagrumab, with one of them being an extension phase III study, and one small series trial on Alemtuzumab. The first clincopathological trial on Bimagrumab showed promising evidence, which were partially confirmed by the double-blinded controlled multicentre trial, however the primary endpoint of improving 6-m walking distance or improving the muscle strength has not been reached. The evidence from the Alemtuzumab trial was also promising, but the risk of bias of the study was relatively high, because it was open labelled, the number of patient was low and the yearly disease progression was much higher than in other recent studies.

Conclusions: Although both Bimagrumab and Alemtuzumab were well tolerated and showed promising results, the Bimagrumab trial did not reach the primary endpoint, and the Alemtuzumab trial has a relatively high risk of bias and the results need to be interpreted with caution.
