RESUMEN

PURPOSE: The authors report a technique of local application of anti-metabolite and corticosteroid mixture in the orbit for treatment of thyroid orbitopathy with moderate-severe inflammation and muscle involvement. METHODS: Patients of one orbital surgeon seen between March 2019 and May 2020 with active thyroid eye disease and restrictive strabismus were considered for local treatment of the myopathic component of the disease. A mixture of 1 ml 5-FU 50 mg/ml, 0.25 ml triamcinolone 40 mg/ml, and 1 ml lidocaine 2% is injected through the skin using a 25-gauge, 1.5-inch needle into the orbit adjacent to the affected extraocular muscle. Six patients were treated in the outpatient setting and 3 patients have been treated with this intervention intraoperatively at the time of orbital decompression. One was treated with the mixture reconstituted with hyaluronic acid (Healon GV) to address postoperative medial rectus fibrosis to the medial wall, this mixture was applied topically in the operative field and not injected. RESULTS: All patients had subjective improvement in the eye movement limitation and 2 patients had a change in motility on exam that was temporally correlated to injections. One patient did not disclose high-dose aspirin intake before injection and experienced a retrobulbar hemorrhage immediately following injection which was successfully treated. No complications were noted as a result of the medication itself. DISCUSSION: The combination of 5-fluorouracil and triamcinolone acetonide for orbital treatment may be a useful adjunct in treating patients with ongoing inflammatory activity, both in the office and in the operating room. The novel combination may optimize ophthalmic outcomes, modifying disease course in some patients.

RESUMEN

PURPOSE: The neutrophil-to-lymphocyte ratio (NLR) is a relatively novel biomarker to distinguish between acute stresses. This study was performed to determine whether the NLR may discern infectious orbital maladies from idiopathic orbital inflammation (IOI). METHODS: The NLR was calculated by a review of the initial blood draws of adult patients who presented to the emergency department at a single academic medical center. Statistical comparisons were performed to identify the significance of these results. RESULTS: Ten patients with IOI, 12 patients with necrotizing fasciitis (NF), and 12 patients with orbital cellulitis (OC) presented to the emergency department. The groups were not statistically significantly different in terms of age or gender. The mean NLRs were 3.48 (standard deviation = 1.80), 13.5 (standard deviation = 14.5), and 8.15 (standard deviation = 6.56) for IOI, NF, and OC, respectively. Patients with IOI had statistically significantly lower NLRs than patients with NF ( p = 0.037) and OC ( p = 0.034). However, the NLRs of patients with OC were not statistically significantly different from those of patients with NF ( p = 0.27). CONCLUSIONS: The NLR appears to distinguish IOI from infectious etiologies, but does not discern between variants of infection. These results should be juxtaposed against appropriate imaging and clinical evaluations, but elevated NLR values may heighten clinicians' concerns for an infectious process and encourage them to initiate appropriate management steps.

RESUMEN

BACKGROUND: Telehealth for paediatric speech and language therapy became one of the most salient modes of service delivery during the COVID-19 pandemic. Evidence for speech and language therapy services via telehealth in comparison to face-to-face delivery demonstrates promising outcomes, and studies have begun to explore practitioner and client experiences. However, across the literature, many critical elements of services are overlooked, and there is a need to frame the evidence base within a theoretical model that can draw out practical implications that consider the range of factors having an impact on clinical implementation in real-world contexts. The APEASE (Acceptability, Practicability, Effectiveness, Affordability, Side-effects, and Equity) criteria offer such a model. The current study explored practising UK speech and language therapists' (SLTs) clinical experience of telehealth through the lens of the APEASE criteria and aimed to identify recommendations for future service provision from the practitioner perspective. METHODS: An online survey structured using the APEASE criteria was developed in collaboration with the UK Royal College of Speech and Language Therapists. Quantitative data were analysed using descriptive statistics and qualitative data were analysed using reflexive thematic analysis. RESULTS: Four hundred and thirty-eight qualified and practicing UK paediatric SLTs completed the survey. Telehealth was broadly acceptable and practicable to SLTs yet there remains some uncertainty about its efficacy and cost-effectiveness compared to face-to-face interventions and how equitable it is for different population groups. SLTs reported that effective implementation of telehealth services was dependent upon several contextual factors; affordability was a perceived barrier to clients having access to telehealth resources, intervention via telehealth was perceived as more acceptable than assessment, and whilst many SLTs welcomed aspects of telehealth, there were concerns about the physical and mental health consequences for practitioners. Six themes for the future development of telehealth in paediatric speech and language therapy were identified: (1) balanced and tailored services; (2) technology and equipment; (3) information and communication; (4) capacity building; (5) monitoring and evaluation; and (6) leadership and governance. CONCLUSIONS: Outcomes highlight promising, concerning and uncertain aspects of telehealth in paediatric speech and language therapy. SLTs value a flexible and tailored approach to service delivery and recommend that effective leadership, clear communication, ongoing policy and guidance development, upskilling of users and careful evaluation of impact are required to ensure optimal implementation. The APEASE criteria offer a valuable opportunity to enhance and streamline practice and research to ensure sustainable implementation of telehealth in the paediatric speech and language therapy services of tomorrow. WHAT THIS PAPER ADDS: What is already known on this subject The COVID-19 pandemic led to the increased use of telehealth as a main mode of service delivery in paediatric speech and language therapy. Pre-COVID-19, evidence for the use of telehealth in this field included small-scale experimental studies that reported on children with particular disorders and explored telehealth outcomes in comparison to face-to-face delivery. The realities of at-scale clinical practice were not well-represented, and critical elements of service such as cost-effectiveness were often overlooked in the paediatric literature. Furthermore, despite emerging global evidence for temporary telehealth responses to the crisis in speech and language therapy, the long-term and future use of telehealth remains unclear. What this paper adds to existing knowledge The current study applied the lens of the APEASE (Acceptability, Practicability, Effectiveness, Affordability, Side-effects, and Equity) criteria, which were used in this case to consider socioeconomic, ecological and cultural factors to capture an overarching understanding of the use of telehealth in paediatric speech and language therapy, and to inform the role of telehealth in future, longer-term and at-scale service development. Results indicated emerging trends in UK paediatric speech and language therapists' (SLTs') perceptions of telehealth and SLTs perceived a hybrid approach to service delivery, combining mostly face-to-face services with some telehealth, was likely to continue in the future. We identified six themes to guide the future development of telehealth in paediatric speech and language therapy services: (1) balanced and tailored services; (2) technology and equipment; (3) information and communication; (4) capacity building; (5) monitoring and evaluation; and (6) leadership and governance. What are the potential or actual clinical implications of this work? UK SLTs believe that speech and language therapy services using telehealth should be reflective, tailored and flexible to meet the requirements and circumstances of the children, young people and families served, as well as the physical and emotional needs of practitioners. SLTs recommend that this service development is clearly communicated to all stakeholders and suggested that those using telehealth should be supported through appropriate training, and ongoing effectiveness should be monitored. Telehealth is here to stay and the APEASE criteria offer a unique opportunity to ensure sustainable models of service delivery; to support co-ordinated leadership at the local, national and international levels and the development of policy and clinical guidance.

RESUMEN

BACKGROUND: The supraclavicular fossa is the dominant location for human brown adipose tissue (BAT). Activation of BAT promotes non-shivering thermogenesis by utilization of glucose and free fatty acids and has been the focus of pharmacological and non-pharmacological approaches for modulation in order to improve body weight and glucose homeostasis. Sympathetic neural control of supraclavicular BAT has received much attention, but its innervation has not been extensively investigated in humans. METHODS: Dissection of the cervical region in human cadavers was performed to find the distribution of sympathetic nerve branches to supraclavicular fat pad. Furthermore, proximal segments of the 4th cervical nerve were evaluated histologically to assess its sympathetic components. RESULTS: Nerve branches terminating in supraclavicular fat pad were identified in all dissections, including those from the 3rd and 4th cervical nerves and from the cervical sympathetic plexus. Histology of the proximal segments of the 4th cervical nerves confirmed tyrosine hydroxylase positive thin nerve fibers in all fascicles with either a scattered or clustered distribution pattern. The scattered pattern was more predominant than the clustered pattern (80% vs. 20%) across cadavers. These sympathetic nerve fibers occupied only 2.48% of the nerve cross sectional area on average. CONCLUSIONS: Human sympathetic nerves use multiple pathways to innervate the supraclavicular fat pad. The present finding serves as a framework for future clinical approaches to activate human BAT in the supraclavicular region.

RESUMEN

BACKGROUND: Accurate early identification of children with low language ability is important but existing measures generally have low sensitivity. This remains an area of concern for preventive and public health services. This study aimed to create and evaluate a measure of child language, communication and related risks which can be used by community health nurses to accurately identify children with low language aged 24-30 months. METHODS: The Early Language Identification Measure (ELIM) was developed and comprised five measurement sections, each measuring different aspects of development combined into a single measure. This was tested blind against a reference standard language measure, the Preschool Language Scale-5 (PLS-5), at the universal 24-30-month health visitor review in England. The threshold for likely low language was the tenth centile or below on the PLS-5. The aim was to ascertain the performance of the five individual sections in the scale, and consider the optimum combination of sections, for predicting low language ability. Specificity, sensitivity, and positive and negative predictive values were reported for each of the five sections of the ELIM alone and in conjunction with each other. The performance for children from monolingual English-speaking families and those who spoke languages other than English were also considered separately. RESULTS: Three hundred and seventy-six children were assessed on both the ELIM identification measure and the PLS-5 with 362 providing complete data. While each section of the ELIM predicted low language ability, the optimal combination for predicting language outcome was the parent reported vocabulary checklist coupled with the practitioner observation of the child's communication and related behaviours. This gave a sensitivity of 0·98 with a specificity of 0·63. CONCLUSIONS: A novel measure has been developed which accurately identifies children at risk of low language, allowing clinicians to target resources efficiently and intervene early.

RESUMEN

PURPOSE: The aim of this study was to map the use of implementation science frameworks, models, and theories in intervention research targeting learning needs in the classroom. METHOD: A scoping review was conducted. Electronic database and manual searches were conducted. Two reviewers independently completed screening, data extraction, and quality appraisal. Qualitative content analysis was undertaken using Nilsen's taxonomy and the domains of the Consolidated Framework for Implementation Research (CFIR). The data were further analyzed using the CFIR valence and strength rating scales. RESULTS: Included papers (n = 22) used a diverse sample of implementation science frameworks and models. Most studies used determinant frameworks to guide data collection and analysis. Few studies used implementation science theory. Most studies were mixed methods (n = 11), published since 2019 (n = 20), and conducted in North America (n = 15). Over half of the interventions targeted social, emotional, and mental health (n = 13). A complex interplay of inner setting factors was identified as having a strong influence on implementation. Teachers' knowledge and beliefs, adaptability, and complexity of interventions were also identified as important considerations when conducting research in this context. CONCLUSIONS: Early engagement with stakeholders in education is recommended when designing universal level speech, language, and communication interventions for use in the ordinary classroom. Adaptive, hybrid designs that test both implementation strategies and effectiveness of interventions may be warranted given the influence of inner setting factors on implementation outcomes.

RESUMEN

BACKGROUND: Ten percent of the school-aged population have speech, language, and communication needs (SLCN) that impact access to the curriculum. Successful implementation of classroom-based SLCN interventions can reduce barriers to learning, thereby improving educational outcomes for this vulnerable population. The challenges of implementing innovations in educational settings are well-documented, yet limited studies have addressed such considerations when developing, and piloting universal level SLCN interventions for use in Irish schools. METHODS: A qualitative exploratory study was undertaken to establish the acceptability, feasibility, and appropriateness of a universal level SLCN intervention. An advisory panel of teachers (n = 8) and children with SLCN (n = 2) were engaged as co-researchers in the study. The Communication Supporting Classrooms Observation Tool, developed as part of the Better Communication Project in the UK, was trialled across a diverse sample of school settings (n = 5). Semi-structured interviews were conducted with school practitioners and school leaders, and a deductive content analysis was undertaken using the domains of the Consolidation Framework for Implementation Research. DISCUSSION: The observation tool was viewed as acceptable with suggested additions. Integrating use of the tool within existing data-informed, school self-evaluation processes aimed at supporting school improvement was noted as a potential means of supporting implementation. A knowledge gap in relation to school-based models of support for SLCN was identified which may negatively impact implementation. An implementation strategy targeting coherence, cognitive engagement and contextual integration is indicated if the tool is to be normalised into routine practice in Irish classrooms. Implementation needs appeared to vary at the school level. CONCLUSIONS: The importance of early-stage exploration to guide implementation planning with regards to developing and testing universal level interventions for SLCN in schools is highlighted. Engaging an advisory panel provides important insights to guide implementation decisions. Findings suggest an adaptive design is required when planning implementation studies targeting classroom setting.

RESUMEN

The possible magnetophoretic migration of iron oxide nanoparticles through the cellulosic matrix within a single layer of paper is challenging with its underlying mechanism remained unclear. Even with the recent advancements of theoretical understanding on magnetophoresis, mainly driven by cooperative and hydrodynamics phenomena, the contributions of these two mechanisms on possible penetration of magnetic nanoparticles through cellulosic matrix of paper have yet been proven. Here, by using iron oxide nanoparticles (IONPs), both nanospheres and nanorods, we have investigated the migration kinetics of these nanoparticles through grade 4 Whatman filter paper with a particle retention of 20-25 µm. By performing droplet tracking experiments, the real-time stained area growth of the particle droplet on the filter paper, under the influences of a grade N40 NdFeB magnet, were recorded. Our results show that the spatial and temporal expansion of the IONP stain is biased toward the magnet and such an effect is dependent on (i) particle concentration and (ii) particle shape. The kinetics data were first analyzed by treating it as a radial wicking fluid, and later the IONP distribution within the cellulosic matrix was investigated by optical microscopy. The macroscopic flow front velocities of the stained area ranged from 259 µm/s to 16 040 µm/s. Moreover, the microscopic magnetophoretic velocity of nanorod cluster was also successfully measured as ∼214 µm/s. Findings in this work have indirectly revealed the strong influence of cooperative magnetophoresis and the engineering feasibility of paper-based magnetophoretic technology by taking advantage of magnetoshape anisotropy effect of the particles.

RESUMEN

OBJECTIVE: To evaluate the accuracy of the initial diagnosis in the case of fungal infections of the orbit and identify factors that may influence patient outcomes. METHODS: An institutional review board-approved retrospective chart review was conducted across 2 large academic centres to identify cases of fungal infections involving the orbit from January 1, 1998, to November 15, 2019. Data collected included patient demographics, past medical history, examination findings, diagnosis, treatment, imaging, and outcomes. RESULTS: Fifty cases of fungal infection involving the orbit were identified. Of these, 33 (66.0%) were initially misdiagnosed as nonfungal diagnoses. Sixteen patients (32.0%) received multiple initial diagnoses. The most common diagnoses on presentation were bacterial cellulitis (n = 12 of 50; 24.0%) and bacterial sinusitis (n = 12 of 50; 24.0%). These were followed by vascular and orbital inflammatory conditions (n = 9 of 50; 18.0%): 5 patients (10.0%) were clinically diagnosed with giant cell arteritis, 3 (6.0%) with nonspecific orbital inflammation, and 1 (2.0%) with optic neuritis. In this subset of patients, 77.8% (n = 7 of 9) were treated initially with systemic steroids. Additional initial diagnoses included neoplastic mass lesions, mucocele, dacryocystitis, cavernous sinus thrombosis, hemorrhage, tick-borne illness, allergic rhinitis, and allergic conjunctivitis. Misdiagnosis was significantly correlated with involvement of the masticator space on imaging (p = 0.04). CONCLUSION: Fungal infections of the orbit are misdiagnosed in 2 of 3 cases. Nearly 15% of patients who are later diagnosed with fungal disease of the orbit were initially treated with systemic steroids. Misdiagnosis is more frequent when the masticator space is involved.

RESUMEN

BACKGROUND AND OBJECTIVE: Low language ability in early childhood is a strong predictor of later psychopathology as well as reduced school readiness, lower educational attainment, employment problems and involvement with the criminal justice system. Assessment of early language development is universally offered in many countries, but there has been little evaluation of assessment tools. We planned to compare the screening performance of two commonly used language assessment instruments. METHODS: A pragmatic diagnostic accuracy study was carried out in five areas of England comparing the performance of two screening tools (Ages and Stages Questionnaire (ASQ) and Sure Start Language Measure (SSLM)) against a reference test (Preschool Language Scale, 5th edition). RESULTS: Results were available for 357 children aged 23-30 months. The ASQ Communication Scale using optimal cut-off values had a sensitivity of 0.55, a specificity of 0.95 and positive and negative predictive values of 0.53 and 0.95, respectively. The SSLM had corresponding values of 0.83, 0.81, 0.33 and 0.98, respectively. Both screening tools performed relatively poorly in families not using English exclusively in the home. CONCLUSION: The very widely used ASQ Communication Scale performs poorly as a language screening tool, missing over one-third of cases of low language ability. The SSLM performed better as a screening tool.

RESUMEN

A stereoselective synthetic entry point to the 5-8-5 carbocyclic core of the ophiobolins was developed. This strategy exploits the chiral tertiary alcohol of ophiobolin A to guide assmebly of the 5-8-5 scaffold in a single step via a photoinitiated cycloisomerization. Mechanistic insights into the origin of stereocontrol in this reaction are described, as are efforts to elaborate the resultant fused 5-8-5 ring system to the pharmacophore of ophiobolin A.

RESUMEN

Background: Methicillin-resistant Staphylococcus aureus (MRSA) decolonization is widely utilized in many medical subspecialities to reduce surgical site infections, but routine ophthalmic implementation has been limited. The aim of this study was to investigate the attitudes and actual practice of corneal specialists and oculoplastic surgeons toward MRSA decolonization as a preventive measure in ophthalmic surgery. Materials and Methods: A web-based survey was sent to cornea specialists and oculoplastic surgeons to assess their knowledge, beliefs, and practices regarding MRSA prophylaxis and the use of MRSA decolonization to prevent post-operative infections. Results: A total of 180 surgeons participated in this study: 71% of respondents agreed that MRSA colonization plays a role in post-operative infection of the eye and adnexal structures; 65% stated that MRSA decolonization could help prevent MRSA infection. Although 41% of respondents would change their management in response to a positive pre-operative MRSA screening result, only 18% performed pre-operative screening. Seventeen percent of respondents indicated that they offer pre-operative decolonization for MRSA-positive patients; the most frequently applied technique was the use of nasal antibiotic agents such as mupirocin, followed by antiseptic baths. Peri-operative MRSA prophylaxis was used by 18% of respondents; pre-operative MRSA decolonization was used in conjunction by 8.5 % of respondents. Conclusions: Although MRSA decolonization has been validated in fields outside of ophthalmology, there has not been widespread adoption of this practice among oculoplastic surgeons and cornea specialists. Prospective MRSA decolonization ophthalmic studies are necessary if evidence-based management guidelines are to be developed.

RESUMEN

Children aged 3-4 years (n = 876) were recruited from deprived areas in England, and a significant minority of the sample were second language learners. Oral language ability was assessed using child administered standardized measures, and parents reported on children's language. We adapted the Language Use Inventory [LUI; (1)] to capture carer's reports of the children's structural language in the language of instruction and their home language (where appropriate). The final measure included six subscales from the original: use of simple words, requests for help, gaining attention, talking about activities/actions, interactions with others, and building sentences. Children's language abilities and non-verbal abilities were below norms on all standardized tests administered except non-word repetition. Factor analysis indicated that all the six scales of the adapted parent completed measure loaded on one language factor. The revised total scale score correlated significantly (p < 0.0005) with child assessed language measures, specifically expressive vocabulary and grammar. Different patterns across gender, language status and parental education were examined. Sensitivity and specificity of the scale to identify children with the greatest delays were evaluated. These preliminary data indicated that parent-reported information on children's language skills at 3 years of age has the potential to provide a reliable indicator to inform pedagogy and practice at the start of nursery school. Study limitations are examined and avenues for future development explored.

RESUMEN

BACKGROUND: Parental education is one of the best predictors of child school achievement. Higher parental education is not only associated with higher child intelligence, but children from highly educated parents also perform better in school due to other family related factors. This study evaluates the relation between parental education, child non-verbal intelligence and parenting practices with child school achievement. METHODS: Longitudinal data from a large population-based, multi-ethnic cohort of children in the Netherlands (63% Dutch origin) followed from birth to age 13 years (3547 children; 52.3% girls) were analyzed. School achievement was measured at the end of primary school (12 years of age) with a national Dutch academic test score. Parental education was assessed at age 3 years. The non-verbal intelligence of the child was measured at age 6 years and a full intelligence was measured at age 13 years. Maternal and paternal family routines, harsh parenting and corporal punishment were assessed in early and mid-childhood. Mediation analysis was performed with the G-formula and Structural Equation Models. RESULTS: Child intelligence partially mediated [B indirect effect =0.54 95% CI (0.46, 0.62) P < 0.001] the association between parental education and child school achievement. Independent of intelligence, family routines [B indirect effect =0.04 95% CI (0.01, 0.07) P < 0.01], but not harsh parenting mediated this association. CONCLUSIONS: Higher parental education was associated with better school achievement through two independent mechanisms, through higher intelligence of the child and parenting practices.

RESUMEN

A new polyene cyclization strategy exploiting ß-ionyl derivatives was developed. Photoinduced deconjugation of the extended π-system within these chromophores unveils a contrathermodynamic polyene that engages in a Heck bicyclization to afford [4.4.1]-propellanes. This cascade improves upon the limited regioselectivity achieved using existing biomimetic tactics and tolerates both electron-rich and electron-deficient (hetero)aryl groups. The utility of this approach was demonstrated with the diverted total synthesis of taxodione and salviasperanol, two isomeric abietane diterpenes that were previously inaccessible along the same synthetic pathway.

RESUMEN

PURPOSE: To review the correction of chin-up abnormal head position (AHP) due to infantile nystagmus syndrome via surgery on the vertical rectus muscles, typically a combined recession-resection of these muscles. METHODS: This was a review of 6 patients who underwent surgical correction of chin-up vertical AHP in the context of infantile nystagmus syndrome at an academic institution. The correction of AHP, visual acuity, ductions, and ocular alignment were noted both preoperatively and postoperatively. The need for repeat surgery, induced strabismus, or correction of AHP were also noted. RESULTS: Six patients underwent surgery for chin-up AHP. A combined recession-resection of the vertical rectus muscles (bilateral inferior rectus muscle recession of 5 to 8 mm; bilateral superior rectus muscle resection of 7 to 8 mm) was performed in 4 of 6 patients, and isolated bilateral recession of the inferior rectus muscles was performed in the remaining 2 patients. Four of 6 patients (67%) achieved complete correction of their AHP at the last follow-up visit, with a mild residual chin-up AHP persisting in the other 2 patients. One patient developed large angle exotropia, one had restrictive hypertropia and horizontal plane null position, and another developed an incomitant horizontal strabismus with exotropia in right gaze. Reoperation was performed in the former 2 patients, with successful correction of the strabismus in each. CONCLUSIONS: Surgery on the vertical rectus muscles can reduce or eliminate a chin-up head position in patients with infantile nystagmus syndrome. Care should be taken to avoid producing a restriction of depression in abduction if the amount of resection is too large. [J Pediatr Ophthalmol Strabismus. 2022;59(6):410-415.].

RESUMEN

BACKGROUND: Early interventions to support young children's language development through responsive parent-child interaction have proven efficacy but are not currently delivered universally. A potential universal delivery platform is the Health Visitor (HV)-led 2-2½-year-old review in England's Healthy Child Programme. It is unclear if it is feasible to offer such interventions through this platform. We report an intervention development process, including extensive stakeholder consultation and co-design which aimed to develop an acceptable, feasible and equitable early language intervention for delivery in this context. METHODS: The study involved five phases including 13 stakeholder co-design workshops with 7 parents and 39 practitioners (HVs, early years practitioners and speech and language therapists): (1) Identification of existing intervention evidence, (2) qualitative review of intervention studies extracting candidate target behaviours for intervention and intervention techniques, (3) co-design workshops with parents and practitioners examining acceptability, barriers and enablers to those behaviours and techniques (particular attention was paid to diverse family circumstances and the range of barriers which might exist), (4) findings were analysed using COM-B and theoretical domains frameworks and a prototype intervention model designed, and (5) co-design workshops iteratively refined the proposed model. RESULTS: Practitioners were committed to offering language intervention at the 2-2½-year-old review but were not sure precisely how to do so. Parents/caregivers wanted to be proactive and to have agency in supporting their own children and to do this as soon as possible. For equitable intervention, it must be proportionate, with higher 'intensity' for higher levels of disadvantage, and tailored, offering differing approaches considering the specific barriers and enablers, assets and challenges in each family. The importance and potential fragility of alliances between parent/caregiver and practitioner were identified as key, and so, strategies to engender successful collaborative partnership are also embedded in intervention design. CONCLUSION: It is possible to develop a universal intervention which parents and practitioners judge would be acceptable, feasible and equitable for use at the 2-2½-year review to promote children's language development. The result is one of the most explicitly developed universal interventions to promote children's language development. Further development and piloting is required to develop materials to support successful widespread implementation.

RESUMEN

BACKGROUND: Children with Developmental Language Disorder (DLD) have a significant deficit in spoken language ability which affects their communication skills, education, mental health, employment and social inclusion. AIM: The present study reports findings from a survey by EU network COST ACTION 1406 and aims to explore differences in service delivery and funding of SLT services for children with DLD across Europe and beyond. METHODS AND PROCEDURES: The survey was completed by 5024 European professionals. COST countries were grouped into Nordic, Anglo-Saxon, Continental, Mediterranean, Central/Eastern and Non-European categories. The use of direct, indirect and mixed interventions, and their relationship to funding available (public, private or mixed) were considered for further analysis. OUTCOMES AND RESULTS: The results revealed that for direct therapy, there were more cases than expected receiving private funding. For indirect therapy, fewer than expected received private and more than expected public funding. For mixed therapy, fewer cases than expected received private funding. CONCLUSIONS AND IMPLICATIONS: The results implies that other factors than evidence-based practices, practitioners experience, and patient preferences, drive choices in therapy. More research is needed to gain a better understanding of factors affecting the choice of therapy.

RESUMEN

While previous research has suggested that lowering athletes' heart rates can enhance sports performance, it is unknown whether slow-paced music might induce a lower heart rate and thereby improve some types of motor performance. In this study, we investigated the effects of different types of music during dart-throw training on both heart rate and dart-throwing performance in 45 (M age = 19.7, SD = 0.31 years) novice dart throwers who were randomly assigned to either a Slow Music Group (SMG), a Fast Music Group (FMG), or a Control Group (CG). All participants completed three dart-throwing blocks - Pre-Test, Practice, and Post-Test. During the Practice block, participants practiced dart-throwing with either slow-paced, fast-paced or no music according to their assigned group. We recorded the participants' heart rates and total dart-throwing accuracy scores during Pre-Test and Post-Test. Music-assisted dart-throw training with slow-paced music was effective in significantly inhibiting a performance-related increase in heart rate and was associated with the greatest dart throwing improvement after training.
