Association of cognitive and adaptive skills with internalizing and externalizing problems in autistic children and adolescents.

The presence of an intellectual disability (ID) alongside autism is considered to increase the risk for mental health and behavior problems in children and adolescents. Existing evidence is restricted by looking at ID as a categorical classification. The study aimed to examine the association of cognitive and adaptive behavior skills with internalizing and externalizing problems in a large sample of autistic children and adolescents, across a wide range of cognitive skills. Participants were 2759 children and adolescents aged between 4 and 18 years recruited as part of the Simons Simplex Collection (SSC), of whom 709 (approximately 25%) had ID. Multiple regression models examined associations of internalizing and externalizing problems with cognitive and adaptive skills (communication, daily living, and socialization skills). Cognitive skills were not associated with externalizing problems but were associated with more internalizing problems in autistic children without ID (Cog ß: 0.126). All adaptive skill domains were inversely associated with externalizing (Communication ß: -0.145; Daily-Living ß: -0.132; Socialization ß: -0.289) and internalizing problems (Communication ß: -0.074; Daily-Living ß: -0.064; Socialization ß: -0.213) in those without ID. Daily living (ß: -0.158) and socialization skills (ß: -0.104) were inversely correlated with externalizing problems in autistic children with ID, while only socialization problems (ß: -0.099) were associated with internalizing problems in this group. Socialization skills were systematically associated with internalizing and externalizing problems across all levels of cognitive functioning. Supporting social skills development may benefit all aspects of child mental health, while recognizing that children with higher cognitive skills are more vulnerable to internalizing problems might assist with earlier identification of these problems.

'Turning up and tuning in'. Factors associated with parental non-attendance and non-adherence in intervention for young children with speech, language communication needs.

BACKGROUND: When parents bring their child to appointments and then adhere to agreed speech and language therapy (SLT) recommendations, there is the potential to increase the intensity of the intervention, support generalization and improve outcomes. In SLT, however, little is known about factors that may promote attendance or adherence. Studies in other clinical areas such in medicine, psychology and physiotherapy have identified risk factors for non-attendance or non-adherence that are multifactorial and variable dependent on, for example, population and intervention. AIMS: To identify rates of non-attendance and non-adherence, and to identify parent or child factors associated with parent involvement in intervention for children under 5 years of age receiving SLT. METHODS: Parents completed questionnaires at two time points assessing the domains of parents' beliefs (problem perceptions, self-efficacy), personal circumstances (socio-demographics, family functioning), treatment experience and child factors. Predictors of parent attendance and adherence were identified through multiple regression analyses. Non-attendance rates were identified via local health records and non-adherence ascertained using a specific parent-reported measure within the treatment experience domain. RESULTS: Participants (N = 199) were predominantly mothers, and were ethnically and socio-economically diverse, speaking a wide range of languages. Their children presented with a range of speech, language communication needs (SLCN). The rate of non-attendance was 25% and the main predictors of non-attendance were maternal age, education level and two factors within the parent beliefs domain. This model explained 40% of the variance in attendance. The rate of non-adherence in this cohort was 26% with parental rating of the importance of a recommendation and self-efficacy beliefs predicting adherence; this explained 56% of the variance in adherence to SLT recommendations at home. CONCLUSIONS & IMPLICATIONS: Our research has provided preliminary evidence of the influence of parents' beliefs, personal circumstances and treatment experiences on their involvement in their child's therapy. Speech and language therapists should consider factors impacting attendance and adherence to treatment and explore parental perceptions of their child's SLCN before embarking on an intervention, a foundation for collaborative practice. A possible limitation of this study is that the levels of attrition in our sample led to generally high measured rates of participation, which should be considered in future studies. Future research should explore adherence in treatments with varying doses, with different types of SLCN or interventions and in different settings. WHAT THIS PAPER ADDS: What is already known on the subject It is acknowledged that parent involvement in their child's therapy, such as attending and adhering to recommendations, is important but little is known about the rates of involvement and what factors may be associated with attendance and adherence in SLT. Qualitative research has explored parental involvement suggesting that beliefs about an intervention may be pertinent. Extensive research in other clinical areas suggest multiple and varied factors are influential and further exploration of particular populations and interventions is necessary. What this paper adds to the existing knowledge This study identified rates of parental non-attendance and non-adherence in a cohort of predominantly mothers of children under the age of 5 years. It is the first study to measure parent adherence in SLT and identify factors that are associated parental adherence to SLT recommendations. It adds to the small body of SLT specific research in understanding risk factors for non-attendance. What are the potential or actual clinical implications of this work? This study highlights the need for a speech and language therapist to consider and explore parents' perspectives of their child's SLCN as a part of achieving collaboration with a parent in order to achieve the best outcomes. It provides a foundation for further systematic research into parent involvement with the ultimate aim of enhancing outcomes for children with SLCN.

Barriers and facilitators to primary care research: views of GP trainees and trainers.

BACKGROUND: Primary care plays an important role in the conception and delivery of transformational research but GP engagement is lacking, prompting calls for the promotion of academic opportunities in primary care. AIM: To identify potential barriers and facilitators among GP trainees and trainers in primary care research to inform support given by Local Clinical Research Networks (LCRNs). DESIGN & SETTING: A cross-sectional online survey was developed and distributed by the CRN to GP trainees and trainers in the North East and North West. METHOD: The survey covered areas including demographics, career intentions, current and potential engagement with research, as well as their general understanding of research in primary care, which included barriers and facilitators to primary care research. RESULTS: Trainees had low intentionality to pursue research and half of trainees did not engage with any research activity. Despite one in five trainees reporting intentions to include research in their career, only 1% would undertake a solely academic career. Medical school region was the only strongly associated factor with academic career intention. Just under 30% of trainers reported engagement in research, but far fewer (8.6%) were interested in contributing to research, and only 10% felt prepared to mentor in research. CONCLUSION: Among trainees, there is limited engagement in and intentionality to pursue research, and this was crucially reflected by responses from trainers. This study identified the need for LCRNs to assist with training in research mentoring and skills, funding opportunities, and to develop resources to promote research in primary care.

Standardisation of delivery and assessment of research training for specialty trainees based on curriculum requirements: recommendations based on a scoping review.

OBJECTIVES: (1) To conduct a scoping review of postgraduate specialty training (ST) curricula for doctors within Health Education England in order to identify common themes and variations in requirements for training and assessment of research competencies. (2) To make recommendations on standardisation of training for clinical research across ST programmes. SETTING: Health Education England North East and National Institute for Health Research Clinical Research Network (CRN)-North East and North Cumbria. METHODS: Annual Review of Competence Progression (ARCP); Certificate of Completion of Training (CCT) checklists and curricula for ST were obtained from Health Education England North East and reviewed between June and September 2015. Research competence requirements based on knowledge, skills or behaviour-based domains were identified and entered onto a spreadsheet for analysis. Common themes with levels of competence required were identified. This information was used to construct and propose a model for delivery of training in clinical research across ST programmes. RESULTS: Sixty-two ST curricula were reviewed and seven common themes for research training were found in up to 97% of the curricula. Requirement for good clinical practice (GCP) in research training was included in 15% of curricula. One of the common themes involved knowledge-based competency, and three each of the remaining seven involved skills or behaviour-based competencies. There was less clarity and larger variation between specialties in how research competencies were assessed; and what evidence was required for ARCP and CCT to assure competence. 63% (19/30) of curricula from medical specialties had no mention of research requirements within their ARCP guidelines. CONCLUSIONS: Given that the majority of specialty curricula contain consistent themes around core research knowledge, consideration should be given to standardising the delivery and assessment of generic research competencies within ST. Our recommendations from this review could form the basis for developing structured research training for specialty trainees involving: (1) a taught course for knowledge-based competencies; (2) clinical placements with CRN teams for practical workplace-based experience and (3) developing research tutors to help support placements and assessment of these competencies.

Finding clean water habitats in urban landscapes: professional researcher vs citizen science approaches.

This study investigated patterns of nutrient pollution in waterbody types across Greater London. Nitrate and phosphate data were collected by both citizen scientists and professional ecologists and their results were compared. The professional survey comprised 495 randomly selected pond, lake, river, stream and ditch sites. Citizen science survey sites were self-selected and comprised 76 ponds, lakes, rivers and streams. At each site, nutrient concentrations were assessed using field chemistry kits to measure nitrate-N and phosphate-P. The professional and the citizen science datasets both showed that standing waterbodies had significantly lower average nutrient concentrations than running waters. In the professional datasets 46% of ponds and lakes had nutrient levels below the threshold at which biological impairment is likely, whereas only 3% of running waters were unimpaired by nutrients. The citizen science dataset showed the same broad pattern, but there was a trend towards selection of higher quality waterbodies with 77% standing waters and 14% of rivers and streams unimpaired. Waterbody nutrient levels in the professional dataset were broadly correlated with landuse intensity. Rivers and streams had a significantly higher proportion of urban and suburban land cover than other waterbody types. Ponds had higher percentage of semi-natural vegetation within their much smaller catchments. Relationships with land cover and water quality were less apparent in the citizen-collected dataset probably because the areas visited by citizens were less representative of the landscape as whole. The results suggest that standing waterbodies, especially ponds, may represent an important clean water resource within urban areas. Small waterbodies, including ponds, small lakes<50ha and ditches, are rarely part of the statutory water quality monitoring programmes and are frequently overlooked. Citizen scientist data have the potential to partly fill this gap if they are co-ordinated to reduce bias in the type and location of the waterbodies selected.

The influence of simulated immigration and chemical persistence on recovery of macroinvertebrates from cypermethrin and 3,4-dichloroaniline exposure in aquatic microcosms.

BACKGROUND: Chemical dissipation and organism immigration are considered important factors that influence recovery potential from perturbation of aquatic macroinvertebrates. Experiments were conducted to investigate the effect of simulated immigration on recovery of aquatic macroinvertebrates exposed in outdoor microcosms to ecotoxicologically similar concentrations of the rapidly dissipating pyrethroid insecticide cypermethrin (70 ng L(-1)) or the more persistent herbicide intermediate and degradate 3,4-dichloroaniline (10 mg L(-1)). Microcosms were covered with light-permeable mesh to prevent recolonisation. Immigration was simulated by the regular addition of organisms after treatment. RESULTS: Microcosms exposed to 3,4-dichloroaniline treatment suffered substantial loss of taxon richness and by 10 months after treatment had only recovered where invertebrates had been added. Those treated with cypermethrin underwent an initial decline in certain crustacean and insect populations. These populations showed some signs of recovery over a period of 5 months through internal processes alone. However, rate of recovery was further enhanced where immigration was simulated, and in this case recovery had occurred around 100 days after treatment. CONCLUSION: Although not the only factors involved, simulated immigration and chemical fate clearly influence the ability of communities to recover from chemical exposure. Consideration of immigration processes and development of models will help to increase the realism of risk assessments.

Implications of computer tomography measurement in the management of renal tumours.

BACKGROUND: To compare radiographic measurement and pathological measurement of renal tumours to see if there was a significant difference between the two as this may have implications in the management. METHODS: We retrospectively analyzed CT measurements of 106 consecutive patients who underwent either radical or nephron sparing surgery in our institution and compared this to the actual measurement of the surgical specimen. The largest axial measurement was compared as this is the primary consideration before offering either treatment modality. RESULTS: The mean age of the patients was 64 years (range 31-92). There were 76 males and 30 females. The median tumour size was 70 mm (range 16-175) on CT and 65 mm (range 15-90) on pathological measurement. 25 patients had a CT size < or = 40 mm. CT tended to overestimate the size of tumours in 41 patients, underestimate in 45 and agree with surgical size in 20 patients. Statistically there was no significant difference between the two measurements (p = 0.7, Wilcoxon sign ranked test). When subdivided into tumours less than 40 mm (p = 0.7) and more than 40 mm (p = 0.09) again there was no statistically significant difference between the two measurements. However in 5(5%) patients who were not offered nephron sparing surgery based on CT findings (size > 40 mm) the pathological size was < or = 40 mm (p = < 0.001, Fishers Exact test). Pathologically the tumours were classified as renal cell carcinoma (n = 98), angiomyolipoma (3), and oncocytoma (5). CONCLUSION: CT measurement of renal tumour size correlates well with the actual size of the tumour. However CT does tend to overestimate the size in a small number of patients which may have a bearing on the modality of treatment offered.

Cardiac MR imaging and MR angiography for assessment of complex tetralogy of Fallot and pulmonary atresia.

Breath-hold electrocardiographically gated cardiac magnetic resonance (MR) imaging and contrast material-enhanced MR angiography are emerging as ideal techniques for the evaluation of complex congenital heart disease. Tetralogy of Fallot is the most common cause of cyanotic congenital heart disease and, in its classic form, is associated with varying degrees of hypoplasia of the central and peripheral pulmonary arteries, with valvar pulmonary atresia and collateral aortopulmonary vessels occupying the extreme end of the spectrum. Accurate assessment of the size and anatomy of the pulmonary arteries is often difficult with echocardiography and conventional cineangiography. Compared with echocardiography in particular, cardiac MR imaging with three-dimensional reconstruction has distinct advantages for pre- or postoperative assessment of pulmonary anatomy in patients with tetralogy of Fallot and pulmonary atresia. MR imaging enables the clear and complete depiction of anatomy and thus can provide additional information about pulmonary artery abnormalities that are difficult to evaluate with conventional cardiac imaging techniques.

US of abnormal uterine bleeding.

Any significant deviation from a woman's established menstrual pattern may be considered abnormal uterine bleeding, and several factors direct evaluation of a patient with such bleeding. Premenopausal disorders that are well evaluated with ultrasound (US) include endometriosis, adenomyosis, and leiomyomas. A positive pregnancy test in a woman of childbearing age prompts a search for an intrauterine pregnancy. Possible complications that may contribute to bleeding include ectopic pregnancy; placental factors including position, trauma, and infection; gestational trophoblastic disease; preterm labor; and postpartum complications. Atrophic changes, hormonal status, and carcinoma are considerations in the postmenopausal patient with abnormal uterine bleeding. Foreign bodies, trauma, infection, polyps, and iatrogenic causes can be observed in all groups. Differential diagnoses for abnormal uterine bleeding in premenopausal, pregnant, and postmenopausal patients are well evaluated with US, and US techniques have greatly facilitated evaluation of pelvic disease. Urgent and emergent conditions such as ectopic pregnancy, placenta previa, and preterm labor are readily identifiable.

How realistic are outdoor microcosms? A comparison of the biota of microcosms and natural ponds.

This study investigated the extent to which aquatic plant and macroinvertebrate assemblages in small outdoor microcosms (cylinders 1.25-m diameter x 1.25 m deep) resembled assemblages found in natural ponds in Britain. Comparisons were made in terms of community structure, species richness, and numbers of uncommon species. Multivariate analysis indicated that, although the microcosms had no exact natural analogues, their plant and animal assemblages were most like those of deep, circumneutral ponds. Unlike natural ponds, the microcosms supported relatively species-poor invertebrate assemblages, lacking uncommon species. Among individual taxa, microcosms supported similar numbers of species of Gastropoda, Isopoda, Amphipoda, and Odonata as natural ponds but significantly fewer Coleoptera, Hemiptera, and Trichoptera species. This was most likely due to the absence of a shallow littoral area in the microcosms. Because of their vertical sides, the microcosms supported no marginal wetland plants, but submerged and floating-leaved plant assemblages were similar in community type and species richness to natural ponds. Refinements to microcosm and mesocosm designs are identified that would enable experimental systems to more closely replicate the assemblages found in natural ponds. In particular, the incorporation of natural margins would be likely to lead to experimental communities that were closer analogues of natural ponds.
