Cognitive strategy use by children with Asperger's syndrome during intervention for motor-based goals

Background:  Cognitive Orientation for (daily) Occupational Performance (CO-OP) is a cognitive approach utilised by occupational therapists to help guide children in the discovery of appropriate strategies for effective task performance through a structured problem-solving process. There has been limited research into its utility for children with Asperger's syndrome (AS). These children often present with motor difficulties, although these are not required for diagnosis of the syndrome. A recent study found that children with AS were able to use the CO-OP framework to enhance their performance of motor-based goals.
Methods:  This paper presents two case studies demonstrating the use of CO-OP with children with AS, and explores the global and domain-specific strategies and types of guidance utilised to improve their task performance. Two children with AS, aged 9 and 11, with above average intellectual ability, engaged in 10 sessions of CO-OP. All sessions were videotaped. One hundred minutes of randomly selected footage were coded per child using the Observer Software Package version 5.0.
Results:  The mean interrater agreement for the two children was 94.06% and 89.30%. Both children (i) utilised the global strategies 'do', followed by 'plan' and 'check', (ii) used at least three domain-specific strategies in each session with 'task specification/modification' and 'body position' utilised most, and (iii) used limited verbal self-guidance.
Conclusion:  These two children with AS were able to utilise cognitive strategies to effectively solve their motor performance problems. Children with AS and those with DCD used similar strategies to achieve motor goals. CO-OP appears to have potential as an effective intervention for children with AS. Study limitations, clinical implications and directions for future research are discussed.     

Efficacy of the cognitive orientation to daily occupational performance with Brazilian children with developmental coordination disorder

Background: Children with Developmental Coordination Disorder (DCD) have difficulties performing daily activities which reflects negatively on participation, impacting their lives.

Objectives: To examine the effects of the cognitive orientation to daily occupational performance Approach (CO-OP Approach) protocol on occupational performance and satisfaction of Brazilian children who have DCD; to examine whether children could transfer strategies and skills learned during CO-OP to untrained goals.

Methods: A pre-post group comparison design with eight boys aged 6–10 years old. Children participated in 12 CO-OP sessions with their parents twice a week, with an extra session added to the protocol for parents´ orientation. The Canadian Occupational Performance Measure and the Performance Quality Rating Scale were used as outcome measures. The study was registered by the United States Institutes of Health at ClinicalTrials.gov (NCT03112746).

Results: Intervention resulted in higher, clinically and statistically significant, occupational performance measures according to parents, children’s, and external evaluators’ perspectives. All children improved occupational performance on their selected goals and five children could transfer the ability to use cognitive strategies to tasks not addressed in therapy.

Conclusions: This study provides initial directions for future research to investigate the applicability and to implement CO-OP approach on pediatric settings in Brazil.     

A tool to enhance occupational therapy reasoning from ICF perspective: The Hasselt Occupational Performance Profile (H-OPP)

Background: In order to enhance occupational therapy reasoning in clinical practice, different elements such as client-centred approach, evidence-based care and interdisciplinary work should be taken into account, but is a challenge.

Aim: To describe the development of the digital Hasselt Occupational Performance Profile (H-OPP^©) that enhances occupational therapy reasoning from ICF perspective.

Method: A participative qualitative design was used to create the H-OPP^© in an iterative way in which occupational therapy lectures, ICF experts, students and occupational therapists in the field were involved.

Results: After linking occupational therapy terminology to the ICF, different stages of the H-OPP were identified and elaborated with main features: generating an occupational performance profile based on inventarization of problems and possibilities, formulating an occupational performance diagnosis and enabling to create an intervention plan. In all stages, both the perspectives of the client and the occupational therapist were taken into account. To increase practical use, the tool was further elaborated and digitalized.

Conclusion: The H-OPP^© is a digital coach that guides and facilitates professional reasoning in (novice) occupational therapists. It augments involvement of the client system. Furthermore, it enhances interdisciplinary communication and evidence-based care.     

Occupational asthma (OA) with sensitization to diphenylmethane diisocyanate (MDI) presenting at the onset like a reactive airways dysfunction syndrome (RADS)

BACKGROUND: Two types of OA are distinguished: immunological (OA with sensitization) and non-immunological, i.e., irritant induced asthma or reactive airways dysfunction syndrome (RADS). METHODS: We describe the case of a worker who developed respiratory symptoms after a spill of diphenylmethane diisocyanate (MDI) at the workplace. RADS was initially diagnosed and the worker resumed working. The progressive worsening of symptoms and the appearance of symptoms-work relationship one year later, when concentrations of isocyanates were no longer "irritant," suggested immunological OA. RESULTS: The diagnosis was confirmed by specific inhalation challenge test, followed by removal from exposure and complete recovery. CONCLUSIONS: In the case of RADS due to an agent with both irritant and sensitizing properties, history should be repeatedly assessed for a possible symptom-work relationship. If this is found, further investigations should be carried out, including specific inhalation challenges, to confirm the possibility of immunological OA.     

Impact of Psychosocial Occupational Therapy Combined with Anodal Transcranial Direct Current Stimulation to the Left Dorsolateral Prefrontal Cortex on the Cognitive Performance of Patients with Schizophrenia: A Randomized Controlled Trial

BackgroundThe most common cognitive dysfunctions in patients with schizophrenia are information processing, memory, and learning. Based on the hypothesis of rehabilitation and brain stimulation in memory and learning, adding a form of neuromodulation to conventional rehabilitation might increase the effectiveness of treatments.AimsTo explore the effects of psychosocial occupational therapy combined with anodal Transcranial Direct Current Stimulation (tDCS) on cognitive performance in patients with Schizophrenia.MethodsTwenty-four patients diagnosed with schizophrenia were randomized into the experimental and control groups. We used The Cambridge Neuropsychological Test Automated Battery (CANTAB) and the Loewenstein Occupational Therapy Cognitive Assessment battery (LOTCA) to assess spatial recognition, attention, visual memory, learning abilities, and high-level cognitive functions like problem-solving. All participants received customized psychosocial occupational therapy activities. Furthermore, the experimental group received 12 sessions of active anodal tDCS for 20 minutes with 2 mA intensity on the left dorsolateral prefrontal cortex (DLPFC) while the patients in the sham group received sham tDCS.ResultsCombining tDCS to conventional psychosocial occupational therapy resulted in a significant increase in spatial memory, visual learning, and attention.ConclusionsAnodal tDCS on the left DLPFC improved visual memory, attention, and learning abilities. Contrary to our expectations, we could not find any changes in complex and more demanding cognitive functions.     

School performance and school behaviour of children affected by acquired immune deficiency syndrome (AIDS) in China

It is generally recognized that the acquired immune deficiency syndrome (AIDS) epidemic will have a negative effect on orphans' school education. However, few studies have been carried out to examine the school performance and school behaviour of AIDS orphans and vulnerable children [children living with human immunodeficiency virus (HIV)-infected parents]. Using both self-report and teacher evaluation data of 1625 children from rural central China, we examined the impact of parental HIV/AIDS on children's school performances (academic marks, educational expectation and student leadership) and school behaviours (e.g. aggression, shyness/anxiety and assertive social skills). Results indicate that AIDS orphans and vulnerable children had disadvantages in school performance in comparison to their peers from the same community who did not experience AIDS-related death and illness in their family (comparison children). AIDS orphans had the lowest academic marks based on the reports of both children and teachers. From a teacher's perspective, educational expectation was significantly lower among AIDS orphans and vulnerable children than comparison children. AIDS orphans were significantly more likely to demonstrate aggressive, impulsive and anxious behaviours than non-orphans. Moreover, orphans have more learning difficulties. Vulnerable children were also at a disadvantage on most measures. The data suggest that greater attention is needed to school performance and behaviour of children affected by AIDS. The findings also indicate that AIDS relief and assistance programmes for children should go beyond school attendance and efforts should be made to improve their school performance and educational aspirations.     

Association of Dietary Vitamin D Intake,Serum 25(OH)D3, 25(OH)D2 with Cognitive Performance in the Elderly

Background: As life expectancy increases, cognitive performance decline in the elderly has become one of the major global challenges. We aimed to evaluate the association of dietary vitamin D (VD), serum 25-hydroxyvitamin D3 (25(OH)D₃), 25-hydroxyvitamin D2 (25(OH)D₂), and total 25-hydroxyvitamin (25(OH)D) concentration with cognitive performance in older Americans. Methods: The data from the National Health and Nutrition Examination Survey (NHANES), 2011–2014 was used. The cognitive performance was assessed by the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) Word Learning sub-test, Animal Fluency test, and Digit Symbol Substitution Test (DSST). A binary logistic regression model was applied to evaluate the association between VD and cognitive performance, and restricted cubic spline model was adopted to evaluate the dose–response relationship. Results: While comparing to the lowest dietary VD intake group, the multivariate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of the highest dietary VD intake group were 0.51 (0.36–0.72) for the Animal Fluency test score and 0.45 (0.31–0.66) for DSST score, respectively; and those of serum total 25(OH)D and 25(OH)D₃ concentration were 0.68 (0.47–0.97) and 0.62 (0.44–0.86) for DSST score. L-shaped relationships were identified for dietary VD intake, serum total 25(OH)D and 25(OH)D₃ concentration with cognition performance. The associations between dietary VD intake, serum total 25(OH)D and cognitive performance were non-significant when stratified by gender. Conclusions: The study indicates that dietary VD intake, serum total 25(OH)D and 25(OH)D₃ concentration were positively associated with cognitive performance. Further studies are needed to clarify the possible effects of dietary VD intake and serum 25(OH)D₂, 25(OH)D₃ on cognitive performance.     

Barriers to uptake of hepatitis C virus (HCV) health intervention among men who have sex with men in Southwest China: A qualitative study

Men who have sex with men (MSM) are at risk of contracting the hepatitis C virus (HCV). Previous studies have documented low uptake of sexually transmitted disease (STD) prevention and health services among Chinese MSM. We carried out qualitative research among MSM in Southwest China. By taking the Health Brief Model (HBM) as a framework, we aimed to determine the underlying factors related to use of HCV health intervention services among MSM. From May to July 2018, we conducted in-depth interviews in Southwest China with 20 participants. Our research revealed that a lack of knowledge about HCV prevention was the main reason why MSM failed to perceive their susceptibility to HCV and had low motivation to seek preventive services. Poor service accessibility and unpleasant experiences seeing doctors also exerted negative influences on health care-seeking behaviour in MSM. More trust and understanding needs to be built between health providers and MSM. Protection of privacy for MSM should be guaranteed in the delivery of health interventions. In addition, the interviewees showed refusal to engage with health interventions being specifically targeted at MSM, which would create a sense of being ‘labelled’. Tailored health interventions may overemphasise their sexuality, segregate them from heterosexuals, and make them feel alienated. Therefore, we speculate that differential treatment may be an obstacle for MSM to become involved in health interventions.
