Conceptualising leadership in early childhood education in Aotearoa New Zealand

The New Zealand Teachers Council Te Pouherenga Kaiako o Aotearoa is pleased to publish this occasional paper focused on leadership in early childhood education in Aotearoa New Zealand. The project that led to this publication grew out of a desire of the Council’s Early Childhood Education Advisory Group to promote some action on leadership development specifically for ECE. Whereas there is a well-developed leadership strategy for the school sector there is no equivalent support for teachers in ECE. Yet it is well established in the literature that an effective professional learning community is most likely to result from leadership that has learning as the central focus. Thus the absence of a cohesive leadership strategy was seen as a significant risk to professional initiatives supporting quality teaching in ECE

IMPROVE-DD: Integrating Multiple Phenotype Resources Optimises Variant Evaluation in genetically determined Developmental Disorders

Diagnosing rare developmental disorders using genome-wide sequencing data commonly necessitates review of multiple plausible candidate variants, often using ontologies of categorical clinical terms. We show that Integrating Multiple Phenotype Resources Optimizes Variant Evaluation in Developmental Disorders (IMPROVE-DD) by incorporating additional classes of data commonly available to clinicians and recorded in health records. In doing so, we quantify the distinct contributions of sex, growth, and development in addition to Human Phenotype Ontology (HPO) terms and demonstrate added value from these readily available information sources. We use likelihood ratios for nominal and quantitative data and propose a classifier for HPO terms in this framework. This Bayesian framework results in more robust diagnoses. Using data systematically collected in the Deciphering Developmental Disorders study, we considered 77 genes with pathogenic/likely pathogenic variants in ≥10 individuals. All genes showed at least a satisfactory prediction by receiver operating characteristic when testing on training data (AUC ≥ 0.6), and HPO terms were the best predictor for the majority of genes, though a minority (13/77) of genes were better predicted by other phenotypic data types. Overall, classifiers based upon multiple integrated phenotypic data sources performed better than those based upon any individual source, and importantly, integrated models produced notably fewer false positives. Finally, we show that IMPROVE-DD models with good predictive performance on cross-validation can be constructed from relatively few individuals. This suggests new strategies for candidate gene prioritization and highlights the value of systematic clinical data collection to support diagnostic programs

HEX17(Neumifil) : an intranasal respiratory biotherapeutic with broad-acting antiviral activity

Funding: This research has been funded by Pneumagen Ltd.Broad-acting antiviral strategies to prevent respiratory tract infections are urgently required. Emerging or re-emerging viral diseases caused by new or genetic variants of viruses such as influenza viruses (IFVs), respiratory syncytial viruses (RSVs), human rhinoviruses (HRVs), parainfluenza viruses (PIVs) or coronaviruses (CoVs), pose a severe threat to human health, particularly in the very young or old, or in those with pre-existing respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD). Although vaccines remain a key component in controlling and preventing viral infections, they are unable to provide broad-spectrum protection against recurring seasonal infections or newly emerging threats. HEX17 (aka Neumifil), is a first-in-class protein-based antiviral prophylactic for respiratory viral infections. HEX17 consists of a hexavalent carbohydrate-binding module (CBM) with high affinity to sialic acids, which are typically present on terminating branches of glycans on viral cellular receptors. This allows HEX17 to block virus engagement of host receptors and inhibit infection of a wide range of viral pathogens and their variants with reduced risk of antiviral resistance. As described herein, HEX17 has demonstrated broad-spectrum efficacy against respiratory viral pathogens including IFV, RSV, CoV and HRV in multiple in vivo and in vitro studies. In addition, HEX17 can be easily administered via an intranasal spray and is currently undergoing clinical trials.Peer reviewe

Survey of Plasmodium in the golden-headed lion tamarin (Leontopithecus chrysomelas) living in urban Atlantic forest in Rio de Janeiro, Brazil

Abstract Background Communicating the presence of potential zoonotic pathogens such as Plasmodium spp. in wild animals is important for developing both animal and human health policies. Methods The translocation of an exotic and invasive population of Leontopithecus chrysomelas (golden-headed lion tamarins) required the screening of these animals for specific pathogens. This studies objective was to investigate Plasmodium spp. infection in the L. chrysomelas, both to know its prevalence in these animals in the local area and to minimize the risk of pathogens being translocated to the destination site. To investigate Plasmodium spp. infection, blood samples from 268 animals were assessed for the presence of Plasmodium spp. by genus-specific PCR and stained thick and thin blood smears were examined by light microscopy. Data of human malaria infection in the studied region was also assembled from SINAN (Diseases Information System Notification—Ministry of Health of Brazil). Results Results from the PCR and microscopy were all negative and suggested that no L. chrysomelas was infected with Plasmodium spp. Analysis of SINAN data showed that malaria transmission is present among the human population in the studied region. Conclusions This study is the first to provide information on Plasmodium spp. infection in L. chrysomelas. Plasmodium spp. infection of this species is rare or absent though malaria parasites circulate in the region. In addition, there is minimal risk of translocating Plasmodium spp. infected animals to the destination site

Approaches to integrated housing, health and social care services: case studies from North Tyneside Council and Northumbria Healthcare

The Care Act 2014 places a duty on local authorities to integrate services, including housing, where this could improve wellbeing by preventing, reducing and/or delaying care needs (LGA 2015). Despite calls for greater collaborative working between housing and health professionals, there are limited examples of live projects taking an integrated approach to service delivery. This case study report presents three case studies of innovative approaches to integrated working across housing, health and adult social care from North Tyneside Council and Northumbria Healthcare Foundation Trust. The case studies highlight the relevance of understanding access processes within different services, the role of workforce development in aligning referral and access pathways, targeted and more cost-effective health intervention delivery via housing services, and the potential for achieving health outcomes through housing improvement. Understanding of these issues informed the approach that was developed for the co-ordination of services and departments to work together across organization and sector boundaries

Psychological distress and quality of life in lung cancer: The role of health-related stigma, illness appraisals and social constraints

Psycho-Oncology Published by John Wiley & Sons Ltd. Objective Health-related stigma is associated with negative psychological and quality of life outcomes in lung cancer patients. This study describes the impact of stigma on lung cancer patients' psychological distress and quality of life and explores the role of social constraints and illness appraisal as mediators of effect. Methods A self-administered cross-sectional survey examined psychological distress and quality of life in 151 people (59% response rate) diagnosed with lung cancer from Queensland and New South Wales. Health-related stigma, social constraints and illness appraisals were assessed as predictors of adjustment outcomes. Results Forty-nine percent of patients reported elevated anxiety; 41% were depressed; and 51% had high global distress. Health-related stigma was significantly related to global psychological distress and quality of life with greater stigma and shame related to poorer outcomes. These effects were mediated by illness appraisals and social constraints. Conclusions Health-related stigma appears to contribute to poorer adjustment by constraining interpersonal discussions about cancer and heightening feelings of threat. There is a need for the development and evaluation of interventions to ameliorate the negative effects of health-related stigma among lung cancer patients

The SOFG Anatomy Entry List (SAEL):an annotation tool for functional genomics data

A great deal of data in functional genomics studies needs to be annotated with low-resolution anatomical terms. For example, gene expression assays based on manually dissected samples (microarray, SAGE, etc.) need high-level anatomical terms to describe sample origin. First-pass annotation in high-throughput assays (e.g. large-scale in situ gene expression screens or phenotype screens) and bibliographic applications, such as selection of keywords, would also benefit from a minimum set of standard anatomical terms. Although only simple terms are required, the researcher faces serious practical problems of inconsistency and confusion, given the different aims and the range of complexity of existing anatomy ontologies. A Standards and Ontologies for Functional Genomics (SOFG) group therefore initiated discussions between several of the major anatomical ontologies for higher vertebrates. As we report here, one result of these discussions is a simple, accessible, controlled vocabulary of gross anatomical terms, the SOFG Anatomy Entry List (SAEL). The SAEL is available from http://www.sofg.org and is intended as a resource for biologists, curators, bioinformaticians and developers of software supporting functional genomics. It can be used directly for annotation in the contexts described above. Importantly, each term is linked to the corresponding term in each of the major anatomy ontologies. Where the simple list does not provide enough detail or sophistication, therefore, the researcher can use the SAEL to choose the appropriate ontology and move directly to the relevant term as an entry point. The SAEL links will also be used to support computational access to the respective ontologies

Tear proteomics in infants at risk of retinopathy of prematurity: a feasibility study

Purpose: This feasibility study investigated the practicability of collecting and analyzing tear proteins from preterm infants at risk of retinopathy of prematurity (ROP). We sought to identify any tear proteins which might be implicated in the pathophysiology of ROP as well as prognostic markers. Methods: Schirmer's test was used to obtain tear samples from premature babies, scheduled for ROP screening, after parental informed consent. Mass spectrometry was used for proteomic analysis. Results: Samples were collected from 12 infants, which were all adequate for protein analysis. Gestational age ranged from 25 + 6 to 31 + 1 weeks. Postnatal age at sampling ranged from 19 to 66 days. One infant developed self-limiting ROP. Seven hundred one proteins were identified; 261 proteins identified in the majority of tear samples, including several common tear proteins, were used for analyses. Increased risk of ROP as determined by the postnatal growth ROP (G-ROP) criteria was associated with an increase in lactate dehydrogenase B chain in tears. Older infants demonstrated increased concentration of immunoglobulin complexes within their tear samples and two sets of twins in the cohort showed exceptionally similar proteomes, supporting validity of the analysis. Conclusions: Tear sampling by Schirmer test strips and subsequent proteomic analysis by mass spectrometry in preterm infants is feasible. A larger study is required to investigate the potential use of tear proteomics in identification of ROP. Translational Relevance: Tear sampling and subsequent mass spectrometry in preterm infants is feasible. Investigation of the premature tear proteome may increase our understanding of retinal development and provide noninvasive biomarkers for identification of treatment-warranted ROP

Sperm DNA fragmentation, recurrent implantation failure and recurrent miscarriage

Evidence is increasing that the integrity of sperm DNA may also be related to implantation failure and recurrent miscarriage (RM). To investigate this, the sperm DNA fragmentation in partners of 35 women with recurrent implantation failure (RIF) following in vitro fertilization, 16 women diagnosed with RM and seven recent fathers (control) were examined. Sperm were examined pre- and post-density centrifugation by the sperm chromatin dispersion (SCD) test and the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. There were no significant differences in the age of either partner or sperm concentration, motility or morphology between three groups. Moreover, there were no obvious differences in sperm DNA fragmentation measured by either test. However, whilst on average sperm DNA fragmentation in all groups was statistically lower in prepared sperm when measured by the SCD test, this was not seen with the results from the TUNEL assay. These results do not support the hypothesis that sperm DNA fragmentation is an important cause of RIF or RM, or that sperm DNA integrity testing has value in such patients. It also highlights significant differences between test methodologies and sperm preparation methods in interpreting the data from sperm DNA fragmentation tests
