This paper provides an overview of the design and cohort characteristics of the Social Spectrum Study: a clinical cohort study that used a two-phase sampling design to identify children at risk for ASD. After screening 1281 children aged 2.5-10 years who had been consecutively referred to one of six mental health services in the Netherlands, children who screened positive for ASD (n = 428) and a random selection of screen negatives (n = 240) were invited to participate in diagnostic assessments and questionnaires regarding the child, family and society. A 1-year follow-up was also conducted. Results from this study may contribute to knowledge of the identification and characterization of children with ASD, family processes, and the impact of ASD on the family and society.

Resistance exercise training is effective to counteract the adverse effects of androgen deprivation therapy (ADT) on body composition, muscle mass and leg strength in prostate cancer patients (PCa). However, it is unknown whether these effects can be autonomously maintained after cessation of the supervised program. Sixty‐eight PCa patients on ADT were included. The exercise intervention group (EX, n = 37) performed 20 weeks of supervised resistance exercise training. Thereafter, patients were advised to autonomously continue exercise training. The control group (CON, n = 31) only received usual care. Outcome measures were compared between baseline and after 1 year. Changes during the intervention (baseline vs. 20 weeks) and follow‐up period (20 weeks vs. 1 year) were descriptively explored. In EX, 83% reported to have continued exercise training themselves. After 1 year, fat mass gains were attenuated in EX compared to CON (1.2 ± 2.6 and 2.8 ± 1.9 kg, respectively; time × treatment effect p = 0.032). The fat percentage increased, and lean mass and quadriceps muscle cross‐sectional area decreased over time, with no differences between groups (overall 1.6 ± 2.1%, −0.7 ± 2.3 kg and −2.2 ± 2.9 cm2, respectively; time effects, all p < 0.05). For muscle strength, an increase of ∼5% in EX was observed, significantly different from the ∼10% decrease in CON (p < 0.001). Subsequent analyses showed that the initial exercise training‐obtained gains in lean mass, muscle mass and strength in EX compared to CON, declined during the follow‐up period. In conclusion, PCa patients on ADT are not capable to autonomously maintain the exercise‐obtained gains of a 20‐week supervised training program over a subsequent 1‐year period. Highlights: ADT for prostate cancer results in many side effects, including muscle mass lossA supervised resistance exercise training program can counteract many side effectsAfter cessation of the supervised program, exercise benefits are not effectively preservedMore focus on sustainability of exercise programs during ADT is required [ABSTRACT FROM AUTHOR]

Aims and objectives To explore which factors determine successful intermittent catheterisation. Background Intermittent catheterisation is a safe, effective treatment and is associated with improved quality of life, although negative issues are reported. Factors which determine adherence are largely unknown. An additional qualitative study was conducted to gain insight into patient's experience with intermittent catheterisation in everyday life. Design A prospective multicentre study was conducted between March 2012-March 2013 with one year follow-up. Methods Patients with a variety of diagnoses referred to the outpatient clinic, ≥18 years, performed catheterisation at least once a day for ≥3 months were included. Data were obtained by patients' specific questionnaire Visual Analog Scale of quality of life regarding voiding problems, a questionnaire about catheterisation in daily practice, King's Health questionnaire, and a short questionnaire after one year. Results Of the 129 (72 male) patients, mean age 62 (22-86) years, seven died and 63 stopped, 32/63 (50%) due to recovered bladder function. Fifty-nine (47%) continued to perform catheterisation after one year. Forty-seven (86%) patients reported catheterisation had become part of their life or had a positive effect on their life. A weak correlation was found between increasing age and cessation of catheterisation. Visual Analogue Scale - score on quality of life improved for the total group. The King's Health questionnaire identified in the total group that the impact of the bladder problem in daily life, limitations in daily activities and negative emotions decreased over time. Conclusion Adherence of successful intermittent catheterisation can be influenced negatively by increasing age. However, we think catheterisation should be considered as an option for older patients. We could not conform that if intermittent catheterisation was beneficial for the patient, it would positively influence adherence. Further prospective studies on adherence of intermittent catheterisation in larger groups need to be undertaken. Relevance to Clinical Practice After implementation of the national guideline in 2008, we were able to perform a multicentre study. This prospective study gives insight into patients who were undertaking intermittent catheterisation and which factors determine successful intermittent catheterisation adherence. After following the national guideline, we found no factors for additional interventions in assessment or coaching intermittent catheterisation. Post void residual volume turned out to be not a predictor for the necessity of intermittent catheterisation. A large group of patients could discontinue intermittent catheterisation during follow-up due to bladder function recovery. Although a weak correlation was found between increasing age and ceasing of catheterisation, we think the older can benefit from intermittent catheterisation. In the first period, additional support, for example given by a district nurse, may be necessary for this group to achieve better outcomes. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study is to evaluate the effect of different levels of realism of context learning on the prescribing competencies of medical students during the clinical clerkship in internal medicine. Methods: Between 2001 and 2007, 164 medical students took part in the prospective explorative study during their clinical clerkship in internal medicine at the VU University Medical Center, Amsterdam, The Netherlands. In a fixed order, each student had to formulate a treatment plan for a real patient in three situations of increasing realism: a minimal level (studying a patient record), medium level (preparing for a therapeutic consultation), and optimal level (preparing for and performing a therapeutic consultation with the patient). Results: In comparison to studying a patient record (minimal context level), preparing a therapeutic consultation (medium context) improved four of the six steps of the WHO six-step plan. Preparing and performing a therapeutic consultation with a real patient (optimal context) further improved three essential prescribing competencies, namely checking for contraindications and interactions, prescription writing, and instructions to the patient. Conclusion and recommendations: The results of this first explorative study suggest that enrichment of the learning context (responsibility for patient care) might be an important factor to improve the training of rational prescribing skills of medical students during their clinical clerkship in internal medicine. Clinical (pharmacology) teachers should be aware that seemingly small adaptations in the learning context of prescribing training during clinical clerkships (i.e., with or without involvement with and responsibility for patient care) may have relatively large impact on the development of prescribing competencies of our future doctors.

Background: Combined lifestyle interventions (CLIs) have been advocated as an effective instrument in efforts to reduce overweight and obesity. The odds of maintaining higher levels of physical activity (PA) and healthier dietary behaviour improve when people are more intrinsically motivated to change their behaviour. To promote the shift towards more autonomous types of motivation, facilitator led CLIs have been developed including lifestyle coaching as key element. The present study examined the shift in types of motivation to increase PA and healthy dieting among participants of a primary care CLI, and the contribution of lifestyle coaching to potential changes in motivational quality. Methods: This prospective cohort study included participants of 29 general practices in the Netherlands that implemented a CLI named ‘BeweegKuur’. Questionnaires including items on demographics, lifestyle coaching and motivation were sent at baseline and after 4 months. Aspects of motivation were assessed with the Behavioural Regulation and Exercise Questionnaire (BREQ-2) and the Regulation of Eating Behaviour Questionnaire (REBS). We performed a drop out analysis to identify selective drop-out. Changes in motivation were analysed with t-tests and effect size interpretations (Cohen’s d), and multivariate regression analysis was used to identify predictors of motivational change. Results: For physical activity, changes in motivational regulation were fully in line with the tenets of Self Determination Theory and Motivational Interviewing: participants made a shift towards a more autonomous type of motivation (i.e. controlled types of motivation decreased and autonomous types increased). Moreover, an autonomy supportive coaching style was generally found to predict a larger shift in autonomous types of motivation. For healthy dietary behaviour, however, except for a small decrease in external motivation, no favourable changes in different types of motivation were observed. The relation between coaching and motivation appeared to be influenced by the presence of physical activity guidance in the programme. Conclusions: Motivation of participants of a real life primary care CLI had changed towards a more autonomous motivation after 4 months of intervention. Autonomy-supportive lifestyle coaching contributed to this change with respect to physical activity. Lifestyle coaching for healthy diet requires thorough knowledge about the problem of unhealthy dieting and solid coaching skills. [ABSTRACT FROM AUTHOR]

Background Definitions and assessment methods of fussy/picky eating are heterogeneous and remain unclear. We aimed to identify an eating behavior profile reflecting fussy/picky eating in children and to describe characteristics of fussy eaters. Methods Eating behavior was assessed with the Child Eating Behavior Questionnaire (CEBQ) in 4914 4-year olds in a population-based birth cohort study. Latent Profile Analysis (LPA) was used to identify eating behavior profiles based on CEBQ subscales. Results and discussion We found a "fussy" eating behavior profile (5.6% of children) characterized by high food fussiness, slowness in eating, and satiety responsiveness in combination with low enjoyment of food and food responsiveness. Fussy eaters were more often from families with low household income than non-fussy eaters (42% vs. 31.8% respectively; X² (1) = 9.97, p < .01). When they were 14 months old, fussy eaters had a lower intake of vegetables (t [3008] = 2.42, p < .05) and fish (t [169.77] = 2.40,p < .05) but higher intake of savory snacks (t [153.69] = -2.03, p < .05) and sweets (t [3008] = -2.30, p < .05) compared to non-fussy eaters. Also, fussy eaters were more likely to be underweight at 4 years of age (19.3%) than non-fussy eaters (12.3%; X² (1) = 7.71, p < .01). Conclusions A distinct fussy eating behavior profile was identified by LPA, which was related to family and child characteristics, food intake, and BMI. This behavior profile might be used in future research and the development of interventions. [ABSTRACT FROM AUTHOR]

Study design:Cross-sectional studyObjective:The Van Lieshout hand function test for tetraplegia (VLT) measures the quality of arm-hand functioning in persons with tetraplegia. It is valid, reliable and responsive. However, it does not satisfy all the criteria for interval level measurement. The present study aims to apply the Rasch model to the VLT short form (VLT-SF) to upgrade its scale type towards interval level, and to verify if the requirements of an objective measure are satisfied in the revised version.Setting:Eight Dutch Rehabilitation centres.Methods:The VLT-SF data of 73 tetraplegic patients were Rasch-analysed (RUMM2030 software, RUMM Laboratory Pty Ltd, Perth, Australia) to verify the order of response categories, unidimensionality and reliability of the VLT-SF, and to assess its applicability regardless of (motor) lesion completeness.Results:Seven of the ten VLT-SF items showed disordered response categories. The six original response categories were therefore recoded into three or four categories. After recoding, all items satisfied the model requirement of unidimensionality. The items were relatively well-targeted on the subjects' arm-hand skilled performance measures, leading to a good person separation index (R=0.91). The difficulty hierarchy of the VLT-SF items was invariant across patient subgroups of (motor) lesion completeness.Conclusions:Provided that response categories are recoded, VLT-SF Rasch analysis showed that the requirements of an objective measure were satisfied. This allows to compare the measurements of different patients quantitatively, and to follow their results over time. [ABSTRACT FROM AUTHOR]
