Investigating the role of language in children's early educational outcomes

Most children develop speech and language skills effortlessly, but some are slow to develop these skills and then go on to struggle with literacy and academic skills throughout their schooling. It is the first few years of life that are critical to their subsequent performance.\ud This project looks at what we know about the early communication environment in a child’s first two years of life, and the role this plays in preparing children for school using data from a large longitudinal survey of young people (ALSPAC - the Avon Longitudinal Study of Parents and Children).\ud It examines the characteristics of the environment in which children learn to communicate (such as activities undertaken with children, the mother’s attitude towards her baby, and the wider support available to the family) and the extent to which this affects a child’s readiness for school entry (defined as their early language, reading, writing, and maths skills that they need in school).\ud \ud Key Findings:\ud •\ud There is a strong association between a child’s social background and their readiness for school as measured by their scores on school entry assessments covering language, reading, maths and writing.\ud •\ud Language development at the age of 2 years predicts children’s performance on entry to primary school. Children’s understanding and use of vocabulary and their use of two or three word sentences at 2 years is very strongly associated with their performance on entering primary school.\ud •\ud The children’s communication environment influences language development. The number of books available to the child, the frequency of visits to the library, parents teaching a range of activities, the number of toys available, and attendance at pre-school, are all important predictors of the child’s expressive vocabulary at 2 years. The amount of television on in the home is also a predictor; as this time increased, so the child’s score at school entry decreased.\ud •\ud The communication environment is a more dominant predictor of early language than social background. In the early stages of language development, it is the particular aspects of a child’s communication environment that are associated with language acquisition rather than the broader socio-economic context of the family.\ud •\ud The child’s language and their communication environment influence the child’s performance at school entry in addition to their social background. Children’s success at school is governed not only by their social background; the child’s communication environment\ud before their second birthday and their language at the age of two years also have a strong influence

Association of proximal elements of social disadvantage with children's language development at 2 years: An analysis of data from the Children in Focus (CiF) sample from the ALSPAC birth cohort

This is the peer reviewed version of the following article: Law, J., Clegg, J., Rush, R., Roulstone, S. & Peters, T. J. (2018) Association of proximal elements of social disadvantage with children's language development at 2 years: An analysis of data from the Children in Focus (CiF) sample from the ALSPAC birth cohort. International Journal of Language & Communication Disorders, which has been published in final form at https://doi.org/10.1111/1460-6984.12442. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions.Background: An association between social disadvantage and early language development is commonly reported in the literature, but less attention has been paid to the way that different aspects of social disadvantage affect both expressive and receptive language in the first 2 years of life. Aims: To examine the contributions of gender, parental report of early language skills and proximal social variables (the amount of stimulation in the home, the resources available to the child and the attitudes/emotional status of the primary carer and the support available to him/her) controlling for distal social variables (family income and maternal education) to children's expressive and receptive language development at 2 years in a community ascertained population cohort. Methods & Procedures: Data from 1314 children in the Children in Focus (CiF) sample from the Avon Longitudinal Study of Parents and Children (ALSPAC) were analyzed. Multivariable regression models identified the contribution of proximal (what parents do with their children) measures of social disadvantage adjusting for more distal (e.g., family income and material wealth) measures as well as early language development at 15 months to the development of verbal comprehension, expressive vocabulary and expressive grammar (word combinations) at 2 years of age. Outcome & Results: In the final multivariable models gender, earlier language and proximal social factors, co‐varying for distal factors predicted 36% of the variance for expressive vocabulary, 22% for receptive language and 27% for word combinations at 2 years. Language development at 15 months remained a significant predictor of outcomes at 24 months. Environmental factors were associated with both expressive scales but the picture was rather more mixed for receptive language suggesting that there may be different mechanisms underlying the different processes. Conclusions & Implications: This study supports the argument that social advantage makes a strong contribution to children's language development in the early years. The results suggest that what parents/carers do with their children is critical even when structural aspects of social disadvantage such as family income and housing have been taken into consideration although this relationship varies for different aspects of language. This has the potential to inform the targeting of public health interventions focusing on early language and pre‐literacy skills on the one hand and home learning environments on the other and, potentially, the two in combination.54pubpub

Adjusting for BMI in analyses of volumetric mammographic density and breast cancer risk

Abstract Background Fully automated assessment of mammographic density (MD), a biomarker of breast cancer risk, is being increasingly performed in screening settings. However, data on body mass index (BMI), a confounder of the MD–risk association, are not routinely collected at screening. We investigated whether the amount of fat in the breast, as captured by the amount of mammographic non-dense tissue seen on the mammographic image, can be used as a proxy for BMI when data on the latter are unavailable. Methods Data from a UK case control study (numbers of cases/controls: 414/685) and a Norwegian cohort study (numbers of cases/non-cases: 657/61059), both with volumetric MD measurements (dense volume (DV), non-dense volume (NDV) and percent density (%MD)) from screening-age women, were analysed. BMI (self-reported) and NDV were taken as measures of adiposity. Correlations between BMI and NDV, %MD and DV were examined after log-transformation and adjustment for age, menopausal status and parity. Logistic regression models were fitted to the UK study, and Cox regression models to the Norwegian study, to assess associations between MD and breast cancer risk, expressed as odds/hazard ratios per adjusted standard deviation (OPERA). Adjustments were first made for standard risk factors except BMI (minimally adjusted models) and then also for BMI or NDV. OPERA pooled relative risks (RRs) were estimated by fixed-effect models, and between-study heterogeneity was assessed by the I 2 statistics. Results BMI was positively correlated with NDV (adjusted r = 0.74 in the UK study and r = 0.72 in the Norwegian study) and with DV (r = 0.33 and r = 0.25, respectively). Both %MD and DV were positively associated with breast cancer risk in minimally adjusted models (pooled OPERA RR (95% confidence interval): 1.34 (1.25, 1.43) and 1.46 (1.36, 1.56), respectively; I 2 = 0%, P >0.48 for both). Further adjustment for BMI or NDV strengthened the %MD–risk association (1.51 (1.41, 1.61); I 2 = 0%, P = 0.33 and 1.51 (1.41, 1.61); I 2 = 0%, P = 0.32, respectively). Adjusting for BMI or NDV marginally affected the magnitude of the DV–risk association (1.44 (1.34, 1.54); I 2 = 0%, P = 0.87 and 1.49 (1.40, 1.60); I 2 = 0%, P = 0.36, respectively). Conclusions When volumetric MD–breast cancer risk associations are investigated, NDV can be used as a measure of adiposity when BMI data are unavailable

Far-Infrared Therapy Induces the Nuclear Translocation of PLZF Which Inhibits VEGF-Induced Proliferation in Human Umbilical Vein Endothelial Cells

Many studies suggest that far-infrared (FIR) therapy can reduce the frequency of some vascular-related diseases. The non-thermal effect of FIR was recently found to play a role in the long-term protective effect on vascular function, but its molecular mechanism is still unknown. In the present study, we evaluated the biological effect of FIR on vascular endothelial growth factor (VEGF)-induced proliferation in human umbilical vein endothelial cells (HUVECs). We found that FIR ranging 3∼10 µm significantly inhibited VEGF-induced proliferation in HUVECs. According to intensity and time course analyses, the inhibitory effect of FIR peaked at an effective intensity of 0.13 mW/cm2 at 30 min. On the other hand, a thermal effect did not inhibit VEGF-induced proliferation in HUVECs. FIR exposure also inhibited the VEGF-induced phosphorylation of extracellular signal-regulated kinases in HUVECs. FIR exposure further induced the phosphorylation of endothelial nitric oxide (NO) synthase (eNOS) and NO generation in VEGF-treated HUVECs. Both VEGF-induced NO and reactive oxygen species generation was involved in the inhibitory effect of FIR. Nitrotyrosine formation significantly increased in HUVECs treated with VEGF and FIR together. Inhibition of phosphoinositide 3-kinase (PI3K) by wortmannin abolished the FIR-induced phosphorylation of eNOS and Akt in HUVECs. FIR exposure upregulated the expression of PI3K p85 at the transcriptional level. We further found that FIR exposure induced the nuclear translocation of promyelocytic leukemia zinc finger protein (PLZF) in HUVECs. This induction was independent of a thermal effect. The small interfering RNA transfection of PLZF blocked FIR-increased PI3K levels and the inhibitory effect of FIR. These data suggest that FIR induces the nuclear translocation of PLZF which inhibits VEGF-induced proliferation in HUVECs

Abiraterone acetate plus prednisolone with or without enzalutamide for patients with metastatic prostate cancer starting androgen deprivation therapy: final results from two randomised phase 3 trials of the STAMPEDE platform protocol

Background: Abiraterone acetate plus prednisolone (herein referred to as abiraterone) or enzalutamide added at the start of androgen deprivation therapy improves outcomes for patients with metastatic prostate cancer. Here, we aimed to evaluate long-term outcomes and test whether combining enzalutamide with abiraterone and androgen deprivation therapy improves survival. Methods: We analysed two open-label, randomised, controlled, phase 3 trials of the STAMPEDE platform protocol, with no overlapping controls, conducted at 117 sites in the UK and Switzerland. Eligible patients (no age restriction) had metastatic, histologically-confirmed prostate adenocarcinoma; a WHO performance status of 0–2; and adequate haematological, renal, and liver function. Patients were randomly assigned (1:1) using a computerised algorithm and a minimisation technique to either standard of care (androgen deprivation therapy; docetaxel 75 mg/m2 intravenously for six cycles with prednisolone 10 mg orally once per day allowed from Dec 17, 2015) or standard of care plus abiraterone acetate 1000 mg and prednisolone 5 mg (in the abiraterone trial) orally or abiraterone acetate and prednisolone plus enzalutamide 160 mg orally once a day (in the abiraterone and enzalutamide trial). Patients were stratified by centre, age, WHO performance status, type of androgen deprivation therapy, use of aspirin or non-steroidal anti-inflammatory drugs, pelvic nodal status, planned radiotherapy, and planned docetaxel use. The primary outcome was overall survival assessed in the intention-to-treat population. Safety was assessed in all patients who started treatment. A fixed-effects meta-analysis of individual patient data was used to compare differences in survival between the two trials. STAMPEDE is registered with ClinicalTrials.gov (NCT00268476) and ISRCTN (ISRCTN78818544). Findings: Between Nov 15, 2011, and Jan 17, 2014, 1003 patients were randomly assigned to standard of care (n=502) or standard of care plus abiraterone (n=501) in the abiraterone trial. Between July 29, 2014, and March 31, 2016, 916 patients were randomly assigned to standard of care (n=454) or standard of care plus abiraterone and enzalutamide (n=462) in the abiraterone and enzalutamide trial. Median follow-up was 96 months (IQR 86–107) in the abiraterone trial and 72 months (61–74) in the abiraterone and enzalutamide trial. In the abiraterone trial, median overall survival was 76·6 months (95% CI 67·8–86·9) in the abiraterone group versus 45·7 months (41·6–52·0) in the standard of care group (hazard ratio [HR] 0·62 [95% CI 0·53–0·73]; p<0·0001). In the abiraterone and enzalutamide trial, median overall survival was 73·1 months (61·9–81·3) in the abiraterone and enzalutamide group versus 51·8 months (45·3–59·0) in the standard of care group (HR 0·65 [0·55–0·77]; p<0·0001). We found no difference in the treatment effect between these two trials (interaction HR 1·05 [0·83–1·32]; pinteraction=0·71) or between-trial heterogeneity (I2 p=0·70). In the first 5 years of treatment, grade 3–5 toxic effects were higher when abiraterone was added to standard of care (271 [54%] of 498 vs 192 [38%] of 502 with standard of care) and the highest toxic effects were seen when abiraterone and enzalutamide were added to standard of care (302 [68%] of 445 vs 204 [45%] of 454 with standard of care). Cardiac causes were the most common cause of death due to adverse events (five [1%] with standard of care plus abiraterone and enzalutamide [two attributed to treatment] and one (<1%) with standard of care in the abiraterone trial). Interpretation: Enzalutamide and abiraterone should not be combined for patients with prostate cancer starting long-term androgen deprivation therapy. Clinically important improvements in survival from addition of abiraterone to androgen deprivation therapy are maintained for longer than 7 years.

The snapshot pre-registration assessment tool. Part 1: background, literature and research.

This is the first of a two-part article that presents a new assessment tool - the snapshot - for pre-registration nurses in clinical practice, that is being used at Kingston University/St George's University of London during year 3 of the Diploma and BSc programmes. A pilot study of the use of the snapshot in a simulation environment had previously been undertaken and as a result of this, the snapshot was piloted as part of continuous clinical assessment in practice on two cohorts of third-year pre-registration student nurses. An evaluative study was undertaken. This article describes the background to the project, the literature and the research methods used to undertake the evaluative research study. Part 2 will focus on the findings and a discussion of these findings mapped against the literature

Using simulation in a vocational programme: Does the method support the theory?

Use of simulation is well established as a way of learning and assessing skills in vocational disciplines. In many institutions the use of simulation with student nurses is being tested as a way of helping them learn clinical skills, problem solving, clinical assessment and decision-making. This paper explores the value of simulation as a learning tool through the presentation of findings from an evaluative research project into the use of simulation in nursing education. The focus of this paper is how students perceive that simulations help them learn and suggests that simulation may play a part in how students perceive learning that is meaningful to them. A literature review on the use of simulation is presented together with literature related to the learning theory that underpins simulation. The methodology, data collection and findings of the evaluative study are then presented followed by a discussion of the findings. Although the original research did not set out to examine how students perceived that simulations influenced their learning, the analysis indicated that this was a significant issue for them. Conclusions are drawn about how learning theory and simulation can be brought together to enhance student learning

The snapshot pre-registration assessment tool. Part 2: data, discussion and future directions

This paper is the second of a two-part article presenting a new assessment tool (the snapshot) for pre-registration nurses in clinical practice that is being used at Kingston University/St George's University of London during year 3 of the Diploma and BSc programme. Part 1 of this article presented background to the snapshot tool and the research approach used in the evaluative research study. Part 2 will present the data collection, findings and discussion which show that the snapshot is perceived positively by students in terms of the criteria, documentation and process. However, mentor understanding of these factors varied with some mentors having an inadequate understanding and additional questions of assessment validity also arose and need to be addressed. Both parts of this article make a contribution to the practice assessment agenda and to the continuous clinical assessment methods currently in use that tests students' competence against agreed criteria. The snapshot reflects the reality of practice and assesses skills in a realistic environment

The contribution of early language development to children's emotional and behavioural functioning at 6 years: An analysis of data from the Children in Focus sample from the ALSPAC birth cohort

© 2014 Association for Child and Adolescent Mental Health. Background: An association between children's early language development and their emotional and behavioural functioning is reported in the literature. The nature of the association remains unclear and it has not been established if such an association is found in a population-based cohort in addition to clinical populations.Methods: This study examines the reported association between language development and emotional and behavioural functioning in a population-based cohort. Data from 1,314 children in the Children in Focus (CiF) sample from the Avon Longitudinal Study of Parents and Children (ALSPAC) were analysed. Regression models identified the extent to which early language ability at 2 years of age and later language ability at 4 years of age is associated with emotional and behavioural functioning at 6 years while accounting for biological and social risk and adjusting for age and performance intelligence (PIQ).Results: A series of univariable and multivariable analyses identified a strong influence of biological risk, social risk and early and later language ability to emotional and behavioural functioning. Interestingly, social risk dropped out of the multivariate analyses when age and PIQ were controlled for. Early expressive vocabulary at 2 years and receptive language at 4 years made a strong contribution to emotional and behavioural functioning at 6 years in addition to biological risk. The final model accounted for 11.6% of the variance in emotional and behavioural functioning at 6 years.Conclusions: The study identified that early language ability at 2 years, specifically expressive vocabulary and later receptive language at 4 years both made a moderate, but important contribution to emotional and behavioural functioning at 6 years of age. Although children's language development is important in understanding children's emotional and behavioural functioning, the study shows that it is one of many developmental factors involved

Nursing Management of the Patient Undergoing Focused Ultrasound: A New Treatment Option for Essential Tremor.

Essential tremor (ET) is among the most common neurological movement disorders that causes postural or action tremors, with an estimated prevalence nationwide of less than 3% of the population. The incidence of ET increases with age but often affects younger adults and has a familial trait association. Depending on disease progression, ET can cause significant limitations for individuals, in many cases, significantly limiting their ability to perform activities of daily living and occupational responsibilities. Until recently, treatment of ET heavily relied on medication management and invasive surgery, such as deep brain stimulation. With advances in the use of focused ultrasound (FUS) for treatment of various medical conditions, recent clinical trials have revealed positive outcomes with the use of FUS as a less invasive approach to treat patients with medication-refractory ET. In a large academic medical center in the mid-Atlantic region, the Department of Neurosurgery conducted a continued access study, recently approved by the Food and Drug Administration, to evaluate the effectiveness of transcranial FUS thalamotomy for the treatment of medication-refractory ET. One patient's experience will be introduced, including discussion of evidence-based treatment options for ET and information on the nursing management of the patient undergoing FUS thalamotomy
