    The Australian, heat-resistant, a virulent V4 strain of Newcastle disease (ND) virus was selected for further heat resistance to give a variant designated V4-UPM. V4-UPM was sprayed on to food pellets which were fed to chickens in amounts calculated to give about 10(6) EID50 per chicken. Chickens vaccinated only once by feeding developed no haemagglutination-inhibition (HI) antibodies and were not protected against challenge with a viscerotropic velogenic strain of ND virus. Chickens given food pellet vaccine at 3 and 6 weeks of age developed HI antibodies and were substantially protected against parenteral and contact challenge with virulent ND virus. Similar protection was achieved when the V4-UPM vaccine was given intranasally on two occasions or when the vaccine virus was allowed to spread by contact from intranasally vaccinated chickens to nonvaccinated chickens. Heat resistant ND vaccine incorporated in food pellets may provide a method for protecting village chickens against ND in tropical countries.

    Droughts are slow-moving natural hazards that gradually spread over large areas and capable of extending to continental scales, leading to severe socio-economic damage. A key challenge is developing accurate drought forecast model and understanding a models' capability to examine different drought characteristics. Traditionally, forecasting techniques have used various time-series approaches and machine learning models. However, the use of deep learning methods have not been tested extensively despite its potential to improve our understanding of drought characteristics. The present study uses a deep learning approach, specifically the Long Short-Term Memory (LSTM) to predict a commonly used drought measure, the Standard Precipitation Evaporation Index (SPEI) at two different time scales (SPEI 1, SPEI 3). The model was compared with other common machine learning method, Random Forests, Artificial Neural Networks and applied over the New South Wales (NSW) region of Australia, using hydro-meteorological variables as predictors. The drought index and predictor data were collected from the Climatic Research Unit (CRU) dataset spanning from 1901 to 2018. We analysed the LSTM forecasted results in terms of several drought characteristics (drought intensity, drought category, or spatial variation) to better understand how drought forecasting was improved. Evaluation of the drought intensity forecasting capabilities of the model were based on three different statistical metrics, Coefficient of Determination (R2), Root Mean Square Error (RMSE), and Mean Absolute Error (MAE). The model achieved R2 value of more than 0.99 for both SPEI 1 and SPEI 3 cases. The variation in drought category forecasted results were studied using a multi-class Receiver Operating Characteristic based Area under Curves (ROC-AUC) approach. The analysis revealed an AUC value of 0.83 and 0.82 for SPEI 1 and SPEI 3 respectively. The spatial variation between observed and forecasted values were analysed for the summer months of 2016-2018. The findings from the study show an improvement relative to machine learning models for a lead time of 1 month in terms of different drought characteristics. The results from this work can be used for drought mitigation purposes and different models need to be tested to further enhance our capabilities.

    Contemporary bioethics education has been developed predominately within Euro-American contexts, and now, other global regions are increasingly joining the field, leading to a richer global understanding. Nevertheless, many standard bioethics curriculum materials retain a narrow geographic focus. The purpose of this article is to use local cases from the Asia-Pacific region as examples for exploring questions such as 'what makes a case or example truly local, and why?', 'what topics have we found to be best explained through local cases or examples?', and 'how does one identify a relevant local case?' Furthermore, we consider the global application of local cases to help extend the possible scope of the discussion, opening new avenues for the development of practical bioethics educational materials. We begin with a background description and discussion of why local cases enhance bioethics education, move to an overview of what is currently available and what is not for the region, and then outline a discussion of what it means to be local using example cases drawn from Hong Kong, Australia, Pakistan, and Malaysia. We are not creating a casebook but rather constructing by example a toolbox for designing active and dynamic learning cases using regional diversity as contextualised cases with generalised principles.

    INTRODUCTION: Weekly iron-folic acid (IFA) supplements are recommended for all menstruating women in countries where anaemia prevalence is >20%. Anaemia caused by folate deficiency is low worldwide, and the need to include folic acid is in question. Including folic acid might reduce the risk of a neural tube defect (NTD) should a woman become pregnant. Most weekly supplements contain 0.4 mg folic acid; however, WHO recommends 2.8 mg because it is seven times the daily dose effective in reducing NTDs. There is a reluctance to switch to supplements containing 2.8 mg of folic acid because of a lack of evidence that this dose would prevent NTDs. Our aim was to investigate the effect of two doses of folic acid, compared with placebo, on red blood cell (RBC) folate, a biomarker of NTD risk.

    METHODS: We conducted a three-arm double-blind efficacy trial in Malaysia. Non-pregnant women (n=331) were randomised to receive 60 mg iron and either 0, 0.4, or 2.8 mg folic acid once weekly for 16 weeks.

    RESULTS: At 16 weeks, women receiving 0.4 mg and 2.8 mg folic acid per week had a higher mean RBC folate than those receiving 0 mg (mean difference (95% CI) 84 (54 to 113) and 355 (316 to 394) nmol/L, respectively). Women receiving 2.8 mg folic acid had a 271 (234 to 309) nmol/L greater mean RBC folate than those receiving 0.4 mg. Moreover, women in the 2.8 mg group were seven times (RR 7.3, 95% CI 3.9 to 13.7; p<0.0001) more likely to achieve an RBC folate >748 nmol/L, a concentration associated with a low risk of NTD, compared with the 0.4 mg group.

    CONCLUSION: Weekly IFA supplements containing 2.8 mg folic acid increases RBC folate more than those containing 0.4 mg. Increased availability and access to the 2.8 mg formulation is needed.

    TRAIL REGISTRATION NUMBER: This trial is registered with the Australian New Zealand Clinical Trial Registry (ACTRN12619000818134).

    BACKGROUND: The visual demands of modern classrooms are poorly understood yet are relevant in determining the levels of visual function required to perform optimally within this environment.

    METHODS: Thirty-three Year 5 and 6 classrooms from eight south-east Queensland schools were included. Classroom activities undertaken during a full school day (9 am to 3 pm) were observed and a range of measurements recorded, including classroom environment (physical dimensions, illumination levels), text size and contrast of learning materials, habitual working distances (distance and estimated for near) and time spent performing various classroom tasks. These measures were used to calculate demand-related minimum criteria for distance and near visual acuity, contrast and sustained use of accommodation and vergence.

    RESULTS: The visual acuity demands for distance and near were 0.33 ± 0.13 and 0.72 ± 0.09 logMAR, respectively (using habitual viewing distances and smallest target sizes) or 0.33 ± 0.09 logMAR assuming a 2.5 times acuity reserve for sustained near tasks. The mean contrast levels of learning materials at distance and near were greater than 70 per cent. Near tasks (47 per cent) dominated the academic tasks performed in the classroom followed by distance (29 per cent), distance to near (15 per cent) and computer-based (nine per cent). On average, children engaged in continuous near fixation for 23 ± 5 minutes at a time and during distance-near tasks performed fixation changes 10 ± 1 times per minute. The mean estimated habitual near working distance was 23 ± 1 cm (4.38 ± 0.24 D accommodative demand) and the vergence demand was 0.86 ± 0.07(Δ) at distance and 21.94 ± 1.09(Δ) at near assuming an average pupillary distance of 56 mm.

    CONCLUSIONS: Relatively high levels of visual acuity, contrast demand and sustained accommodative-convergence responses are required to meet the requirements of modern classroom environments. These findings provide an evidence base to inform prescribing guidelines and develop paediatric vision screening protocols and referral criteria.

    BACKGROUND: Research into capital punishment has focussed on the length of time it will take to abolish. It will take decades or centuries. A key moment in the movement to abolish the death penalty was the 1980s when the Second Optional Protocol to the ICCPR was developed. This was also the decade that the last significant changes were made to the United Nations drug conventions. At the time, awareness of the issue of capital punishment for drug offences was increasing around the world as more people were getting executed. This article looks at how western countries and the United Nations responded to Malaysia which introduced the mandatory death penalty for drug offences in 1982.

    METHODS: Over 30,000 pages of documents have been accessed through the National Archives of Australia in Canberra. These have been photographed, scanned and converted to OCR. The most relevant folders have then been analysed through NVivo 12 to look for relevant mentions of the research question: capital punishment and Malaysia. All probative data is then presented in the article.

    RESULTS: The data from National Archives suggests that the UN, Australia, and other western countries were happy to continue supporting Malaysia's drug policy and to elect it to high positions at UN meetings despite their public proclamations that they were opposed to the death penalty.

    CONCLUSION: Applying a critical juncture approach, the article concludes that the 1980s was a critical juncture in the movement to abolish the death penalty but abolitionist countries allowed capital punishment to continue for drug offences. This may have set back the abolition movement by decades.

    BACKGROUND: Older people use many medications, but combinations of medications used among the oldest old (≥ 80 years) are not commonly reported.

    AIMS: This study aimed to determine common combinations of medications used among women aged 77-96 years and to describe characteristics associated with these combinations.

    METHODS: A cohort study of older women enroled in the Australian Longitudinal Study on Women's Health over a 15-year period was used to determine combinations of medications using latent class analysis. Multinomial logistic regression was used to determine characteristics associated with these combinations.

    RESULTS: The highest medication users during the study were for the cardiovascular (2003: 80.28%; 2017: 85.63%) and nervous (2003: 66.03%; 2017: 75.41%) systems. A 3-class latent model described medication use combinations: class 1: 'Cardiovascular & neurology anatomical group' (27.25%) included participants using medications of the cardiovascular and nervous systems in their later years; class 2: 'Multiple anatomical group' (16.49%) and class 3: 'Antiinfectives & multiple anatomical group' (56.27%). When compared to the reference class (class 1), the risk of participants being in class 3 was slightly higher than being in class 2 if they had > 4 general practitioner visits (RRR 2.37; 95% CI 2.08, 2.71), Department of Veterans Affairs' coverage (RRR 1.59; 95% CI 1.36, 1.86), ≥ 4 chronic diseases (RRR 3.16; 95% CI 2.56, 3.90) and were frail (RRR 1.47; 95% CI 1.27, 1.69).

    CONCLUSION: Identification of combinations of medication use may provide opportunities to develop multimorbidity guidelines and target medication reviews, and may help reduce medication load for older individuals.

    A twin registry is a registry of twin pairs (monozygotic = MZ and Dizygotic = DZ) who are willing to consider participating in health-related research. Twins are able to help researchers study the impact of genetic and environmental factors on health and the treatment and prevention of disease in a special way. Throughout the world, twin registries have been established by the governments via the National Health and Medical Research in order to put researchers in touch with twins who might be willing to take part in particular projects. In Australia, for example, more than 30,000 pairs of twins have joined the registry, making it the largest volunteer registry of its kind in the world. However, in some countries such as Denmark, the first twin registry was born in a medical faculty and it was then expanded to the National Twin Registry of Denmark. (Copied from article).

    The term Developing Nations has to be used with caution as it had traditionally included a wide array of countries outside the developed world of North America, Western Europe and Japan (and a few other countries such as Australia and South Africa). The characteristics which defined these “emerging markets” were a Gross National Product (GNP) per capita which was below that of the developed economies, the potential for market growth and an environment with continued economic and political instability. However, as many of these countries have grown at different rates and have economic and other drivers which are very different and disparate, definitions of this sector have become more fragmented.

    Clidicus Laporte, 1832 currently comprises 27 species distributed in India (Karnataka, Tamil Nadu), Sri Lanka, Indonesia (Java, Kalimantan, Sumatra), Malaysia (Sabah, Sarawak), Laos, Vietnam, the Philippines (Mindanao), China (Hainan) and Australia (Queensland). Some species have conspicuously large adults reaching 8.5 mm, and they represent the largest known Scydmaeninae. Species of Clidicus were relatively poorly known until recently, when Orousset (2014) revised a large portion of this genus and described several new species. Other major studies include Besuchet (1971), who described Sri Lankan species, Jałoszyński et al. (2003) who recorded four new species from Vietnam and Laos, Jałoszyński (2009) with the first description of a Philippine species, and Zhou Li (2015), who discovered the first species in China. Another new species, representing the second Clidicus occurring in the Philippines, is described below.

    Burkholderia pseudomallei is the causative agent of melioidosis, an
    infectious disease endemic in Southeast Asia and northern Australia. Cases have been
    reported in Pahang, Johor Bahru and Kedah. The disease is difficult to combat as B.
    pseudomallei has shown resistance to various antibiotics and much is still not understood
    about its pathogenicity. It is suggested that investigating the bacterium hypothetical
    proteins may provide potential new targets for the development of antimicrobials. The
    gene of interest in this study, BPSL2774, encoding BPSL2774 hypothetical protein, is a
    target gene that was predicted as essential using transposon-directed insertion site
    sequencing technique (TraDIS). We aimed to express and purify soluble GST-tagged
    BPSL2774 protein at sufficient concentration for future functional assays. (Copied from article).
