Floristics, structure and site characteristics of "Melaleuca viridiflora" (Myrtaceae) dominated open woodlands of the wet tropics lowlands

Tropical lowland plant communities in north-eastern Queensland remain under pressure from continuing clearing, fragmentation, exotic species invasion, inappropriate fire regimes, and altered hydrological patterns. Comparatively little scientific research has been conducted on the highly diverse and ecologically significant range of remnant vegetation types. Additionally, most plant communities remain very poorly represented in the existing conservation reserve system. Melaleuca viridiflora Sol. ex Gaertn. open woodlands were selected for investigation based on their relatively simple structure, compared to other lowland communities, and the large extent to which they have been affected by past clearing patterns. A detailed analysis of community structure and composition was conducted at 24 sites throughout the wet-tropics coastal region between Townsville and Cooktown. Surprisingly, a high diversity of structural and floristic types was recorded, with a total of 127 species documented across the 24 sites. Classification analyses of species composition data produced seven or eight main groups of sites (dependent on the statistical technique used), essentially related to a gradient of latitude and rainfall. These floristic groups were not well explained by either species richness, past fire frequencies or soil types. Structural classification analyses based upon DBH data identified six or seven main groups, the singularly most striking of which were sites with annual fire histories. Ordinations based on both the DBH and species composition data produced groupings that supported those detected by the classification techniques. On closer examination of sites with similar fire histories, soil moisture and soil type were both found to have significant effects on community structure and composition. Many of the woodland types recorded are not adequately included (some not at all) in the existing conservation reserve system

Hiding from the sun - Vitamin D deficiency in refugees

Permission to reproduce must be sought from the publisher, The Royal Australian College of General Practitioners.BACKGROUND It has been well established that women who wear a veil for cultural reasons and dark skinned migrants from Africa have an increased prevalence of vitamin D deficiency. Many refugee patients also come from countries where their skin is covered or they are indoors for most of the day. OBJECTIVE This article explores the risk, diagnosis and management of vitamin D deficiency in the Australian refugee population. DISCUSSION In 2004–2005, 75% of the 7000 refugees settling in Australia were from African countries and 20% were from the Middle East. Refugees may be exposed to less sunlight in Australia than in their country of origin because of an indoor lifestyle or an increased latitude. Refugee health centres confirm that vitamin D deficiency is present in 40–80% of refugee patients. Importantly, this is often asymptomatic. General practitioners are encouraged to test for vitamin D deficiency in refugees, especially as part of the initial health assessment.Jill Benson; Sue Skul

What factors hinder the decision-making process for women with cancer and contemplating fertility preservation treatment?

Background: Although fertility preservation (FP) treatment options have increased, the existing evidence suggests that many women with cancer do not feel well supported in making these decisions, but find them stressful and complex and fail to take up fertility care at this crucial time. Whilst existing reviews have all made important contributions to our understanding of the FP decision-making process, none of them examine solely and specifically these processes for women of reproductive age with a diagnosis of any cancer, leaving a gap in the knowledge base. Given the expectation that care is patient-centred, our review aims to address this gap which may be of help to those managing patients struggling to make difficult decisions in the often brief period before potentially sterilising cancer treatment is started. Objective and rationale: Underpinning this narrative review was the question “What factors hinder the decision-making process for women with any cancer and contemplating FP treatment?” Our objectives were to i) assess and summarise this existing literature, ii) identify the factors that hinder this decision-making process, iii) explore to what extent these factors may differ for women choosing different methods of FP, and iv) make recommendations for service delivery and future research. Search methods: A systematic search of the medical and social science literature from the 1st January 2005 up to the end of January 2016 was carried out using three electronic databases (Web of Science (PubMed), Ovid SP Medline and CINAHL via Ebsco). Included in the review were quantitative, qualitative and mixed-method studies. Reference lists of relevant papers were also hand searched. From the 983 papers identified, 46 papers were included. Quality assessment was undertaken using the Mixed Methods Appraisal Tool and thematic analysis was used to analyse the data. Outcomes: From the analysis, six key themes with 15 sub-themes emerged: 1) fertility information provision (lack of information, timing of the information, patient-provider communication); 2) fear concerning the perceived risks associated with pursuing FP (delaying cancer treatment, aggravating a hormone positive cancer, consequences of a future pregnancy); 3) non-referral from oncology (personal situation, having a hormone positive cancer, not a priority, transition between service issues); 4) the dilemma (in survival mode, whether to prioritise one treatment over another); 5) personal situation (parity, relationship status); and 6) costs (financial concerns). Wider implications: This review has found that a wide range of internal and external factors impact the FP decision-making process. Key external issues related to current service delivery such as the provision and timing of FP information, and lack of referral from oncology to the fertility clinic. However, internal issues such as women’s fears concerning the perceived risks associated with pursuing FP also hindered decision-making but these ‘risks’ were typically overestimated and non-evidence based. These findings suggest that the implementation of a range of decision support interventions may be of benefit within the clinical care pathway of FP and cancer. Women would benefit from the provision of more evidence-based FP information, ideally received at cancer diagnosis, in advance of seeing a fertility specialist, for example through the implementation of patient decision aids. Health care professionals in both oncology and fertility services may also benefit from the implementation of training programs and educational tools targeted at improving the communication skills needed to improve collaborative decision-making and deliver care that is patient-centred. Exploration of the current barriers, both intellectual and practical, that prevent some patients from accepting FP will help care providers to do better for their patients in the future. Finally, the extent to which a poor prognosis and moral, ethical and religious beliefs influence the FP decision-making process also warrant further research

Induced endometrial trauma (endometrial scratch) in the mid-luteal menstrual cycle phase preceding first cycle IVF/ICSI versus usual IVF/ICSI therapy: study protocol for a randomised controlled trial

Endometrial trauma commonly known as endometrial scratch (ES) has been shown to improve pregnancy rates in women with a history of repeated implantation failure undergoing in vitro fertilisation (IVF), with or without intracytoplasmic sperm injection (ICSI). However, the procedure has not yet been fully explored in women having IVF/ICSI for the first time. This study aims to examine the effect of performing an ES in the mid-luteal phase prior to a first-time IVF/ICSI cycle on the chances of achieving a clinical pregnancy and live birth. If ES can influence this success rate, there would be a significant cost saving to the National Health Service through decreasing the number of IVF/ICSI cycles necessary to achieve a pregnancy, increase the practice of single embryo transfer and consequently have a large impact on risks and costs associated with multiple pregnancies. This 30-month, UK, multicentre, parallel group, randomised controlled trial includes a 9-month internal pilot and health economic analysis recruiting 1044 women from 16 fertility units. It will follow up participants to identify if IVF/ICSI has been successful and live birth has occurred up to 6 weeks post partum. Primary analysis will be on an intention-to-treat basis. A substudy of endometrial samples obtained during the ES will assess the role of immune factors in embryo implantation. Main trial recruitment commenced on January 2017 and is ongoing.Participants randomised to the intervention group will receive the ES procedure in the mid-luteal phase of the preceding cycle prior to first-time IVF/ICSI treatment versus usual IVF/ICSI treatment in the control group, with 1:1 randomisation. The primary outcome is live birth rate after completed 24 weeks gestation. South Central-Berkshire Research Ethics Committee approved the protocol. Findings will be submitted to peer-reviewed journals and abstracts to relevant national and international conferences. ISRCTN23800982; Pre-results

“Why Did You Do That?” A Teacher’s Quest to Finding a Solution to Social-Emotional Learning in a Transitional Classroom

The purpose of this study was to explore what would happen when a mood board and social-emotional centers were implemented in a transitional first-grade classroom. The goal was to understand how the students would express themselves after receiving this learning and the student and teacher perceptions on social-emotional learning (SEL). Field notes were taken daily for observation when students used SEL language. Surveys and student and teacher interviews were conducted over a four-week span. These were coded using the constant comparative method, grouping together similar categories in the data to create 16 level 1 codes and five level 2 codes. The study found that there were major differences in the boys’ perceptions of sharing big feelings than the girls. It also found that the students held their personal value highly in receiving the classroom reward incentives and tied a lot of their own emotions to their family\u27s wellbeing

Pneumococcal conjugate vaccines PREVenar13 and SynflorIX in sequence or alone in high-risk Indigenous infants (PREV-IX_COMBO): protocol of a randomised controlled trial.

INTRODUCTION: Otitis media (OM) starts within weeks of birth in almost all Indigenous infants living in remote areas of the Northern Territory (NT). OM and associated hearing loss persist from infancy throughout childhood and often into adulthood. Educational and social opportunities are greatly compromised. Pneumococcus and non-typeable Haemophilus influenzae (NTHi) are major OM pathogens that densely colonise the nasopharynx and infect the middle ear from very early in life. Our hypothesis is that compared to current single vaccine schedules, a combination of vaccines starting at 1 month of age, may provide earlier, broadened protection. METHODS AND ANALYSES: This randomised outcome assessor, blinded controlled trial will recruit 425 infants between 28 and 38 days of age and randomly allocate them (1:1:1) to one of three pneumococcal conjugate vaccine (PCV) schedules: Synflorix at 2, 4, 6 months of age, Prevenar13 at 2, 4 and 6 months of age, or an investigational schedule of Synflorix at 1, 2 and 4 months plus Prevenar13 at 6 months of age. The blinded primary outcomes at 7 months of age are immunogenicity of specific vaccine antigens (geometric mean concentration (GMC) and proportion of participants with above threshold GMC of 0.35 µg/L). Secondary outcomes at all timepoints are additional immunogenicity measures and proportion of participants with nasopharyngeal carriage of vaccine-type pneumococci and NTHi, and any OM, including any tympanic membrane perforation. Parental interviews will provide data on common risk factors for OM. ETHICS AND DISSEMINATION: Ethical approval has been obtained from NT Department of Health and Menzies HREC (EC00153), Central Australian HREC (EC00155) and West Australian Aboriginal Health Ethics Committee (WAAHEC- 377-12/2011). Final trial results, data analyses, interpretation and conclusions will be presented in appropriate written and oral formats to parents and guardians, participating communities, local, national and international conferences, and published in peer-reviewed open access journals.
