The foxtail palm (Wodyetia bifurcata), an Australian native species, is an adaptable and fast-growing landscape tree. The foxtail palm is most commonly used in landscaping in Malaysia. Coconut yellow decline (CYD) is the major disease of coconut associated with 16SrXIV phytoplasma group in Malaysia (1). Symptoms consistent with CYD, such as severe chlorosis, stunting, general decline, and death were observed in foxtail palms from the state of Selangor in Malaysia, indicating putative phytoplasma infection. Symptomatic trees loses their green and vivid appearance as a decorative and landscape ornament. To determine the presence of phytoplasma, samples were collected from the fronds of 12 symptomatic and four asymptomatic palms in September 2012, and total DNA was extracted using the CTAB method (3). Phytoplasma DNA was detected in eight symptomatic palms using nested PCR with universal phytoplasma 16S rDNA primer pairs, P1/P7 followed by R16F2n/R16R2 (2). Amplicons (1.2 kb in length) were generated from symptomatic foxtail palms but not from symptomless plants. Phytoplasma 16S rDNAs were cloned using a TOPO TA cloning kit (Invitrogen). Several white colonies from rDNA PCR products amplified from one sample with R16F2n/R16R2 were sequenced. Phytoplasma 16S rDNA gene sequences from single symptomatic foxtail palms showed 99% homology with a phytoplasma that causes Bermuda grass white leaf (AF248961) and coconut yellow decline (EU636906), which are both members of the 16SrXIV 'Candidatus Phytoplasma cynodontis' group. The sequences also showed 99% sequence identity with the onion yellows phytoplasma, OY-M strain, (NR074811), from the 'Candidatus Phytoplasma asteris' 16SrI-B subgroup. Sequences were deposited in the NCBI GenBank database (Accession Nos. KC751560 and KC751561). Restriction fragment length polymorphism (RFLP) analysis was done on nested PCR products produced with the primer pair R16F2n/R16R2. Amplified products were digested separately with AluI, HhaI, RsaI, and EcoRI restriction enzymes based on manufacturer's specifications. RFLP analysis of 16S rRNA gene sequences from symptomatic plants revealed two distinct profiles belonging to groups 16SrXIV and 16SrI with majority of the 16SrXIV group. RFLP results independently corroborated the findings from DNA sequencing. Additional virtual patterns were obtained by iPhyclassifier software (4). Actual and virtual patterns yielded identical profiles, similar to the reference patterns for the 16SrXIV-A and 16SrI-B subgroups. Both the sequence and RFLP results indicated that symptoms in infected foxtail palms were associated with two distinct phytoplasma species in Malaysia. These phytoplasmas, which are members of two different taxonomic groups, were found in symptomatic palms. Our results revealed that popular evergreen foxtail palms are susceptible to and severely affected by phytoplasma. To our knowledge, this is the first report of a mixed infection of a single host, Wodyetia bifurcata, by two different phytoplasma species, Candidatus Phytoplasma cynodontis and Candidatus Phytoplasma asteris, in Malaysia.

Fulltext Job satisfaction among Community-Based Rehabilitation (CBR) workers in caring for disabled persons in the east coast region of Peninsular Malaysia

Hasan H, Aljunid SM

BMC Public Health, 2019 Feb 19;19(1):208.
PMID: 30782152 DOI: 10.1186/s12889-019-6520-z

BACKGROUND: Job satisfaction influences staff retention, motivation, and performance in providing services. A considerable amount of published studies has reported on the job satisfaction level of healthcare workers, but to date, very few studies focused on Community-Based Rehabilitation (CBR) workers. This study aimed to explore the job satisfaction level among Community-Based Rehabilitation (CBR) workers and associated factors related to their overall job satisfaction.
METHODS: A one-year survey was conducted in three states of the east coast region of Peninsular Malaysia involving 204 CBR workers selected through universal sampling method where all CBR staff who fulfilled the inclusion criteria were selected as participants. Self-completed questionnaires consisted of 20 association factors on six-point Likert scale responses were distributed. Total mean satisfaction level and mean associated factors were reported in this study.
RESULTS: The results showed that the majority of the participants were between 20 and 40 years old (72%), female (96%), Malay (99%) and had 1-5 years of working experience. The mean total satisfaction score was 79.8 ± SD = 7.85. The highest mean satisfaction level for the associated factor was 4.6 ± SD = 0.59 with about 95% of the participants were satisfied that "CBR programme is a challenging work", while the lowest satisfaction level for associated factor was on "salary of community-based rehabilitation staff is acceptable", with mean score of 2.3 ± SD = 0.97 with about 59% of the participants felt dissatisfied. The results of this study determined that the highest dissatisfied factors among CBR workers were on salary.
CONCLUSION: These findings provided useful information for policymakers to evaluate this issue for a sustainable CBR programme in the future.
TRIAL REGISTRATION: This study has been registered for trial as 'retrospective registered' in the Australian New Zealand Clinical Trials Registry (ANZCTR) (registration no.: ACTRN 12618001101279 ) on 5th October 2018.

Assessment of the phytochemical profiles of novel hop (Humulus lupulus L.) cultivars: A potential route to beer crafting

Yan D, Wong YF, Shellie RA, Marriott PJ, Whittock SP, Koutoulis A

Food Chem, 2019 Mar 01;275:15-23.
PMID: 30724181 DOI: 10.1016/j.foodchem.2018.09.082

This study investigated the volatile phytochemical diversity of 30 samples obtained from experimental hybrid and commercial H. lupulus L. plants. Essential oils distilled from these samples were analysed by high resolution gas chromatography coupled with accurate mass time-of-flight mass spectrometry (GC-accTOFMS). A total of 58 secondary metabolites, mainly comprising 18 esters, 6 monoterpene hydrocarbons, 2 oxygenated monoterpenes, 20 sesquiterpene hydrocarbons, 7 oxygenated sesquiterpenes, and 4 ketones, were positively or tentatively identified. A total of 24 metabolites were detected in all samples, but commercial cultivars (selected for brewing performance) had fewer compounds identified compared to experimental genotypes. Chemometrics analyses enabled distinct differentiation of experimental hybrids from commercial cultivars, discussed in terms of the different classes of compounds present in different genotypes. Differences among the mono- and sesquiterpenoids, appear to be related to either: i) the genetic origin of the plants; or ii) the processes of bioaccumulation of the identified secondary metabolites.

The potential for walkability to narrow neighbourhood socioeconomic inequalities in physical function: A case study of middle-aged to older adults in Brisbane, Australia

Loh VH, Rachele JN, Brown WJ, Ghani F, Washington S, Turrell G

Health Place, 2019 03;56:99-105.
PMID: 30716668 DOI: 10.1016/j.healthplace.2019.01.020

Residents of disadvantaged neighbourhoods have poorer physical function than their advantaged counterparts, although the reasons for this remain largely unknown. We examined the moderating effects of walkability in the relationship between neighbourhood disadvantage and physical function using 2013 cross-sectional data from 5115 individuals aged 46-72 living in 200 neighbourhoods in Brisbane, Australia. The relationship between neighbourhood disadvantage and physical function differed by levels of walkability: positive associations as levels of walkability increased for those living in more disadvantaged neighbourhoods, and no difference for those living in more advantaged neighbourhoods. Further work is required to better understand the underlying mechanisms.

History and current activities of the International Diabetes Federation-Western Pacific Region (IDF-WPR)

Baba S

Diabetes Res Clin Pract, 1994 Oct;24 Suppl:S325-9.
PMID: 7859629 DOI: 10.1016/0168-8227(94)90271-2

International Diabetes Federation (IDF) is one of the biggest non-governmental organizations with its 44-year history since 1950. In 1993, 114 diabetes associations in 96 countries participated in the IDF. In 1982, it was decided to divide the globe into seven regions and to promote the diagnosis, treatment, care and education of diabetes based on the environment, natural features, culture and race of the each region. On January 24, 1984, the IDF-WPR establishment meeting was held in Melbourne, Australia, with eight original member countries (Australia, New Zealand, Korea, The Philippines, Malaysia, Singapore, Fiji and Japan). In 1993, 13 diabetes associations in 12 countries joined the IDF-WPR. New member associations are from China (Beijing and Taipei), Hong Kong, Papua New Guinea and Indonesia. The IDF-WPR has been holding congresses and council meetings every 3 or 4 years since 1984 as well as formulating strategic action plans in the scientific, clinical, health care and education fields of diabetes.

My precarious career in photosynthesis: a roller-coaster journey into the fascinating world of chloroplast ultrastructure, composition, function and dysfunction

Chow WS

Photosynth Res, 2021 Aug;149(1-2):5-24.
PMID: 33543372 DOI: 10.1007/s11120-021-00818-2

Despite my humble beginnings in rural China, I had the good fortune of advancing my career and joining an international community of photosynthesis researchers to work on the 'light reactions' that are a fundamental process in Nature. Along with supervisors, mentors, colleagues, students and lab assistants, I worked on ionic redistributions across the photosynthetic membrane in response to illumination, photophosphorylation, forces that regulate the stacking of photosynthetic membranes, the composition of components of the photosynthetic apparatus during acclimation to the light environment, and the failure of the photosynthetic machinery to acclimate to too much light or even to cope with moderate light due to inevitable photodamage. These fascinating underlying mechanisms were investigated in vitro and in vivo. My career path, with its ups and downs, was never secure, but the reward of knowing a little more of the secret of Nature offset the job uncertainty.

Fulltext A cost-effectiveness comparison of the NICE 2015 and WHO 2013 diagnostic criteria for women with gestational diabetes with and without risk factors

Jacklin PB, Maresh MJ, Patterson CC, Stanley KP, Dornhorst A, Burman-Roy S, et al.

BMJ Open, 2017 Aug 11;7(8):e016621.
PMID: 28801424 DOI: 10.1136/bmjopen-2017-016621

OBJECTIVES: To compare the cost-effectiveness (CE) of the National Institute for Health and Care Excellence (NICE) 2015 and the WHO 2013 diagnostic thresholds for gestational diabetes mellitus (GDM).
SETTING: The analysis was from the perspective of the National Health Service in England and Wales.
PARTICIPANTS: 6221 patients from four of the Hyperglycaemia and Adverse Pregnancy Outcomes (HAPO) study centres (two UK, two Australian), 6308 patients from the Atlantic Diabetes in Pregnancy study and 12 755 patients from UK clinical practice.
PRIMARY AND SECONDARY OUTCOME MEASURES PLANNED: The incremental cost per quality-adjusted life year (QALY), net monetary benefit (NMB) and the probability of being cost-effective at CE thresholds of £20 000 and £30 000 per QALY.
RESULTS: In a population of pregnant women from the four HAPO study centres and using NICE-defined risk factors for GDM, diagnosing GDM using NICE 2015 criteria had an NMB of £239 902 (relative to no treatment) at a CE threshold of £30 000 per QALY compared with WHO 2013 criteria, which had an NMB of £186 675. NICE 2015 criteria had a 51.5% probability of being cost-effective compared with the WHO 2013 diagnostic criteria, which had a 27.6% probability of being cost-effective (no treatment had a 21.0% probability of being cost-effective). For women without NICE risk factors in this population, the NMBs for NICE 2015 and WHO 2013 criteria were both negative relative to no treatment and no treatment had a 78.1% probability of being cost-effective.
CONCLUSION: The NICE 2015 diagnostic criteria for GDM can be considered cost-effective relative to the WHO 2013 alternative at a CE threshold of £30 000 per QALY. Universal screening for GDM was not found to be cost-effective relative to screening based on NICE risk factors.

Cross-Situational Self-Consistency in Nine Cultures: The Importance of Separating Influences of Social Norms and Distinctive Dispositions

Locke KD, Church AT, Mastor KA, Curtis GJ, Sadler P, McDonald K, et al.

Pers Soc Psychol Bull, 2017 Jul;43(7):1033-1049.
PMID: 28903706 DOI: 10.1177/0146167217704192

We assessed self-consistency (expressing similar traits in different situations) by having undergraduates in the United States ( n = 230), Australia ( n = 220), Canada ( n = 240), Ecuador ( n = 101), Mexico ( n = 209), Venezuela ( n = 209), Japan ( n = 178), Malaysia ( n = 254), and the Philippines ( n = 241) report the traits they expressed in four different social situations. Self-consistency was positively associated with age, well-being, living in Latin America, and not living in Japan; however, each of these variables showed a unique pattern of associations with various psychologically distinct sources of raw self-consistency, including cross-situationally consistent social norms and injunctions. For example, low consistency between injunctive norms and trait expressions fully explained the low self-consistency in Japan. In accord with trait theory, after removing normative and injunctive sources of consistency, there remained robust distinctive noninjunctive self-consistency (reflecting individuating personality dispositions) in every country, including Japan. The results highlight how clarifying the determinants and implications of self-consistency requires differentiating its distinctive, injunctive, and noninjunctive components.

Signatures of polygenic adaptation associated with climate across the range of a threatened fish species with high genetic connectivity

Harrisson KA, Amish SJ, Pavlova A, Narum SR, Telonis-Scott M, Rourke ML, et al.

Mol Ecol, 2017 Nov;26(22):6253-6269.
PMID: 28977721 DOI: 10.1111/mec.14368

Adaptive differences across species' ranges can have important implications for population persistence and conservation management decisions. Despite advances in genomic technologies, detecting adaptive variation in natural populations remains challenging. Key challenges in gene-environment association studies involve distinguishing the effects of drift from those of selection and identifying subtle signatures of polygenic adaptation. We used paired-end restriction site-associated DNA sequencing data (6,605 biallelic single nucleotide polymorphisms; SNPs) to examine population structure and test for signatures of adaptation across the geographic range of an iconic Australian endemic freshwater fish species, the Murray cod Maccullochella peelii. Two univariate gene-association methods identified 61 genomic regions associated with climate variation. We also tested for subtle signatures of polygenic adaptation using a multivariate method (redundancy analysis; RDA). The RDA analysis suggested that climate (temperature- and precipitation-related variables) and geography had similar magnitudes of effect in shaping the distribution of SNP genotypes across the sampled range of Murray cod. Although there was poor agreement among the candidate SNPs identified by the univariate methods, the top 5% of SNPs contributing to significant RDA axes included 67% of the SNPs identified by univariate methods. We discuss the potential implications of our findings for the management of Murray cod and other species generally, particularly in relation to informing conservation actions such as translocations to improve evolutionary resilience of natural populations. Our results highlight the value of using a combination of different approaches, including polygenic methods, when testing for signatures of adaptation in landscape genomic studies.

Sharifdini M, Ghanbarzadeh L, Kouhestani-Maklavani N, Mirjalali H, Saraei M

Iran J Parasitol, 2017 Jul-Sep;12(3):374-381.
PMID: 28979347

BACKGROUND: Hookworm infection is one of the important Neglected Tropical Diseases (NTD) in the world. It was previously more prevalent in the northern and southern parts of Iran with a prevalence rate higher than 40% in some endemic regions; nevertheless, the infection rate has decreased to less than 1%. This study aimed to determine prevalence and molecular aspects of hookworm infections in rural inhabitants of Fouman County, Guilan Province, northern Iran.

METHODS: This cross-sectional study was performed in 31 villages of Fouman district in Guilan Province, northern Iran during 2015-2016. Stool samples were collected from 1500 rural inhabitants and examined by formalin ethyl-acetate concentration as well as agar plate culture techniques. After treatment with albendazole, adult hookworms were isolated. Following DNA extraction, PCR amplification of ITS2-rDNA region was performed and the product was sequenced, followed by genetic variation analysis.

RESULTS: Of 1500 samples, one case was morphologically diagnosed as N. americanus. In addition, molecular characterization verified the presence of N. americanus, showing more than 95% similarity with sequences of N. americanus present in GenBank. The patient showed no clinical symptoms and a mild hypereosinophilia was the only laboratory finding observed.

CONCLUSION: A reduced prevalence of human hookworms was demonstrated within Guilan Province located in north of Iran. The N. americanus originated from Guilan had a high homology with the isolates found in Japan, Laos, Malaysia, and Australia.

Consensus Validation of Simpler™: A Tool to Improve Pharmacist Delivery of Quality, Evidence-Based Diabetes Care

Ayadurai S, Sunderland VB, Tee LBG, Hattingh HL

Curr Diabetes Rev, 2018;14(6):565-575.
PMID: 29243582 DOI: 10.2174/1573399814666171215115239

BACKGROUND: Studies on a structured method used by pharmacists to provide comprehensive, evidence-based diabetes care are lacking. The aim of this study was to prioritise, rank and construct validate indicators categorised as seven treatment factors utilised in the management of type 2 diabetes namely: Cholesterol, blood pressure and glycaemia control; medication and lifestyle management; cardiovascular risk management and patient education using the Delphi process.
METHODS: A Delphi questionnaire consisted of 29 Part 1 and nine Part 2 indicators which were incorporated into a tool called Simpler™. The indicators were mainly sourced from American, Australian and Malaysian diabetes management guidelines. Diabetes experts were asked to rank indicators in the order of importance in Part 1. In Part 2, indicators had to be chosen for inclusion into Simpler™ using a fivepoint Likert scale. The consensus level was pre-set at 60%.
RESULTS: A three round Delphi process was used to validate all 38 indicators by 12 experts from Australia and Malaysia: five pharmacists, four doctors, two endocrinologists and a diabetes nurse. Consensus was reached for 93.1% (27/29) of the Part 1 indicators and all nine Part 2 indicators (100%). Five out of nine indicators in Part 2 questionnaire obtained consensus disagreement for inclusion into the Simpler ™ tool.
CONCLUSION: The Simpler™ tool is the first structured diabetes multifactorial tool to address all seven evidence-based factors. The tool was refined and validated by multi-disciplinary health professionals from Australia and Malaysia. Pharmacists can use the Simpler™ tool to facilitate evidence-based comprehensive individualised care among type 2 diabetes patients.

Fulltext Examination of Sarcocystis spp. of giant snakes from Australia and Southeast Asia confirms presence of a known pathogen - Sarcocystis nesbitti

Wassermann M, Raisch L, Lyons JA, Natusch DJD, Richter S, Wirth M, et al.

PLoS One, 2017;12(11):e0187984.
PMID: 29131856 DOI: 10.1371/journal.pone.0187984

We examined Sarcocystis spp. in giant snakes from the Indo-Australian Archipelago and Australia using a combination of morphological (size of sporocyst) and molecular analyses. We amplified by PCR nuclear 18S rDNA from single sporocysts in order to detect mixed infections and unequivocally assign the retrieved sequences to the corresponding parasite stage. Sarcocystis infection was generally high across the study area, with 78 (68%) of 115 examined pythons being infected by one or more Sarcocystis spp. Among 18 randomly chosen, sporocyst-positive samples (11 from Southeast Asia, 7 from Northern Australia) the only Sarcocystis species detected in Southeast Asian snakes was S. singaporensis (in reticulated pythons), which was absent from all Australian samples. We distinguished three different Sarcocystis spp. in the Australian sample set; two were excreted by scrub pythons and one by the spotted python. The sequence of the latter is an undescribed species phylogenetically related to S. lacertae. Of the two Sarcocystis species found in scrub pythons, one showed an 18S rRNA gene sequence similar to S. zamani, which is described from Australia for the first time. The second sequence was identical/similar to that of S. nesbitti, a known human pathogen that was held responsible for outbreaks of disease among tourists in Malaysia. The potential presence of S. nesbitti in Australia challenges the current hypothesis of a snake-primate life cycle, and would have implications for human health in the region. Further molecular and biological characterizations are required to confirm species identity and determine whether or not the Australian isolate has the same zoonotic potential as its Malaysian counterpart. Finally, the absence of S. nesbitti in samples from reticulated pythons (which were reported to be definitive hosts), coupled with our phylogenetic analyses, suggest that alternative snake hosts may be responsible for transmitting this parasite in Malaysia.

General nutrition knowledge among carers at group homes for people with intellectual disability

Hamzaid NH, Flood VM, Prvan T, O'Connor HT

J Intellect Disabil Res, 2018 05;62(5):422-430.
PMID: 29484759 DOI: 10.1111/jir.12480

BACKGROUND: Good nutrition knowledge among carers of people with intellectual disability (ID) living in group homes is essential as they have a primary role in food provision for residents. Research on the nutrition knowledge of carers is limited.
METHOD: This cross-sectional study assessed the level of general nutrition knowledge in a convenience sample of Australian carers (C) of people with ID and compared this to the general Australian community (CM). Nutrition knowledge was evaluated using the validated General Nutrition Knowledge Questionnaire. Total knowledge score as well as performance on instrument sub-sections (dietary guidelines, nutrient sources, healthy food choices and diet disease relationships) were assessed (expressed as %). Knowledge scores were adjusted for known confounders (age, sex, education level, BMI, living arrangement and English spoken at home) using generalised linear modelling.
RESULTS: A total of 589 participants were recruited (C: n = 40; CM: n = 549). Age (C: 40.8 ± 12.1 year; CM: 37.8 ± 13.3 years; P = 0.145), sex distribution (C: 62.5%; CM: 67.2% female; P = 0.602) and English spoken at home (C: 82.5%; CM: 89.6%; P = 0.183) were similar between groups, but BMI (C: 28.5 ± 5.7 kgm-2 ; CM: 25.3 kgm-2 ; P = 0.002) was significantly lower and tertiary education (C: 52.5%; CM: 85.1%; P

Cross-Cultural Invariance of the Mental Toughness Inventory Among Australian, Chinese, and Malaysian Athletes: A Bayesian Estimation Approach

Gucciardi DF, Zhang CQ, Ponnusamy V, Si G, Stenling A

J Sport Exerc Psychol, 2016 Apr;38(2):187-202.
PMID: 27390084 DOI: 10.1123/jsep.2015-0320

The aims of this study were to assess the cross-cultural invariance of athletes' self-reports of mental toughness and to introduce and illustrate the application of approximate measurement invariance using Bayesian estimation for sport and exercise psychology scholars. Athletes from Australia (n = 353, Mage = 19.13, SD = 3.27, men = 161), China (n = 254, Mage = 17.82, SD = 2.28, men = 138), and Malaysia (n = 341, Mage = 19.13, SD = 3.27, men = 200) provided a cross-sectional snapshot of their mental toughness. The cross-cultural invariance of the mental toughness inventory in terms of (a) the factor structure (configural invariance), (b) factor loadings (metric invariance), and (c) item intercepts (scalar invariance) was tested using an approximate measurement framework with Bayesian estimation. Results indicated that approximate metric and scalar invariance was established. From a methodological standpoint, this study demonstrated the usefulness and flexibility of Bayesian estimation for single-sample and multigroup analyses of measurement instruments. Substantively, the current findings suggest that the measurement of mental toughness requires cultural adjustments to better capture the contextually salient (emic) aspects of this concept.

Level of natural hepatotoxin (Indospicine) contamination in Australian camel meat

Tan ET, Al Jassim R, D'Arcy BR, Fletcher MT

Food Addit Contam Part A Chem Anal Control Expo Risk Assess, 2016 Oct;33(10):1587-1595.
PMID: 27575484

Camel meat production for human consumption and pet food manufacture accounts for a relatively small part of overall red meat production in Australia. Reliable statistical data for the Australian production and consumption of camel meat are not available; however, it is estimated that 300,000 feral camels roam within the desert of central Australia, with an annual usage of more than 3000 camels for human consumption, 2000 for pet food manufacture and a smaller number for live export. Despite a small Australian camel meat production level, the usage of camel meat for pet food has been restricted in recent years due to reports of serious liver disease and death in dogs consuming camel meat. This camel meat was found to contain residues of indospicine, a non-proteinogenic amino acid found in certain Indigofera spp., and associated with mild to severe liver disease in diverse animals after dietary exposure to this hepatotoxin. The extent of indospicine-contaminated Australian camel meat was previously unknown, and this study ascertains the prevalence of such residue in Australian camel meat. In this study, indospicine levels in ex situ (95 samples collected from an abattoir in Queensland) and in situ (197 samples collected from camels after field culling in central Australia) camel meat samples were quantitated using a validated ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The quantitation results showed 46.7% of the in situ- and 20.0% of the ex situ-collected camel meat samples were contaminated by indospicine (more than the limit of detection (LOD) of 0.05 mg kg(-1) fresh weight). The overall indospicine concentration was higher (p < 0.05) in the in situ-collected samples. Indospicine levels detected in the present study are considered to be low; however, a degree of caution must still be exercised, since the tolerable daily intake for indospicine is currently not available for risk estimation.

Fulltext Optimising technology to measure functional vision, mobility and service outcomes for people with low vision or blindness: protocol for a prospective cohort study in Australia and Malaysia

Deverell L, Meyer D, Lau BT, Al Mahmud A, Sukunesan S, Bhowmik J, et al.

BMJ Open, 2017 12 21;7(12):e018140.
PMID: 29273657 DOI: 10.1136/bmjopen-2017-018140

INTRODUCTION: Orientation and mobility (O&M) specialists assess the functional vision and O&M skills of people with mobility problems, usually relating to low vision or blindness. There are numerous O&M assessment checklists but no measures that reduce qualitative assessment data to a single comparable score suitable for assessing any O&M client, of any age or ability, in any location. Functional measures are needed internationally to align O&M assessment practices, guide referrals, profile O&M clients, plan appropriate services and evaluate outcomes from O&M programmes (eg, long cane training), assistive technology (eg, hazard sensors) and medical interventions (eg, retinal implants). This study aims to validate two new measures of functional performance vision-related outcomes in orientation and mobility (VROOM) and orientation and mobility outcomes (OMO) in the context of ordinary O&M assessments in Australia, with cultural comparisons in Malaysia, also developing phone apps and online training to streamline professional assessment practices.
METHODS AND ANALYSIS: This multiphase observational study will employ embedded mixed methods with a qualitative/quantitative priority: corating functional vision and O&M during social inquiry. Australian O&M agencies (n=15) provide the sampling frame. O&M specialists will use quota sampling to generate cross-sectional assessment data (n=400) before investigating selected cohorts in outcome studies. Cultural relevance of the VROOM and OMO tools will be investigated in Malaysia, where the tools will inform the design of assistive devices and evaluate prototypes. Exploratory and confirmatory factor analysis, Rasch modelling, cluster analysis and analysis of variance will be undertaken along with descriptive analysis of measurement data. Qualitative findings will be used to interpret VROOM and OMO scores, filter statistically significant results, warrant their generalisability and identify additional relevant constructs that could also be measured.
ETHICS AND DISSEMINATION: Ethical approval has been granted by the Human Research Ethics Committee at Swinburne University (SHR Project 2016/316). Dissemination of results will be via agency reports, journal articles and conference presentations.

Pertanika Journal of Science & Technology, 2017;25(1):121-138.
MyJurnal

The present study aimed to examine the levels of diabetes knowledge, attitudes, self-management and quality of life (QoL) between two countries with different cultural and language backgrounds. Data collection was conducted in two hospitals in Melbourne, Australia, and a hospital in Kelantan, Malaysia. Participants with type 2 diabetes mellitus (T2DM) were asked to complete four questionnaires, measuring diabetes knowledge, attitudes, self-management, and QoL. The differences between the samples were
examined using chi-square and independent samples t-tests. The variables of gender and type of treatment (using insulin or not using insulin for treatment) based on groups were analysed using one-way ANOVA. All analyses were conducted using SPSS 22.0. The results highlighted some similarities and differences between the Australia-based sample and the Malaysia-based sample. In general, the Australia-based participants scored significantly higher in diabetes knowledge and reported more regular self-management of T2DM in exercise, blood glucose testing and foot care. The Australia-based sample also scored higher on attitudes compared to the Malaysia-based participants. On the other hand, Malaysia-based participants reported a lower level of impacts of T2DM on QoL. There was no significant difference between self-management of T2DM in terms of diet and satisfaction as an aspect of QoL related to living with diabetes between the two samples. The present study highlighted the levels of diabetes knowledge, attitudes, self-management, and QoL among Australia-based and Malaysia-based people with T2DM.

Fulltext Determining the spatial autocorrelation of dengue vector populations: influences of mosquito sampling method, covariables, and vector control

Azil AH, Bruce D, Williams CR

J Vector Ecol, 2014 Jun;39(1):153-63.
PMID: 24820568 DOI: 10.1111/j.1948-7134.2014.12082.x

We investigated spatial autocorrelation of female Aedes aegypti L. mosquito abundance from BG-Sentinel trap and sticky ovitrap collections in Cairns, north Queensland, Australia. BG-Sentinel trap collections in 2010 show a significant spatial autocorrelation across the study site and over a smaller spatial extent, while sticky ovitrap collections only indicate a non-significant, weak spatial autocorrelation. The BG-Sentinel trap collections were suitable for spatial interpolation using ordinary kriging and cokriging techniques. The uses of Premise Condition Index and potential breeding container data have helped improve our prediction of vector abundance. Semiovariograms and prediction maps indicate that the spatial autocorrelation of mosquito abundance determined by BG-Sentinel traps extends farther compared to sticky ovitrap collections. Based on our data, fewer BG-Sentinel traps are required to represent vector abundance at a series of houses compared to sticky ovitraps. A lack of spatial structure was observed following vector control treatment in the area. This finding has implications for the design and costs of dengue vector surveillance programs.

Fulltext Cigarette smoking among school children in Singapore. Part I--Smoking prevalence

Emmanuel SC, Ho CK, Chen AJ

Singapore Med J, 1990 Jun;31(3):211-6.
PMID: 2392697

A cross sectional nationally representative survey of 33,110 school-going children in Singapore aged between 9 and 20 years was carried out to obtain, for the first time, baseline information on smoking among the school-going population in Singapore. The survey was carried out among students attending vocational institutes and public sector schools in Singapore in 1987. The overall smoking prevalence was found to be 2% (3% among boys and 0.2% among girls). Ex-smokers comprised 2% of respondents whilst those who had only experimented with smoking made up 9% of the respondents. Analyses of the data showed that cigarette smoking was more prevalent among Malays, among boys, among older children, and among the less academically inclined. On average, boys smoked a median of 20 cigarettes a week and girls, 12 cigarettes a week. On an international basis, the smoking prevalence among the school-going population in Singapore is significantly lower than that of developed countries like Australia, England and Wales and neighbouring countries such as Malaysia.
