RESUMEN
Although hookworm is highly prevalent in the Solomon Islands, the species involved are unknown. We initiated this study in response to finding Ancylostoma ceylanicum hookworm in a peacekeeper in Australia who had returned from the Solomon Islands. Kato-Katz fecal surveys performed in 2013 and 2014 in 2 village groups in East Malaita, Solomon Islands, identified hookworm-positive samples. These specimens were tested by cytochrome oxidase 1 (cox-1) gene multiplex PCR and sequenced. Of 66 positive specimens, 54 (81.8%) contained only Necator americanus, 11 (16.7%) contained only A. ceylanicum, and 1 (1.5%) contained both species. A. duodenale was not found. Haplotype analysis of cox-1 sequences placed all human isolates (99% bootstrap support) of A. ceylanicum within the zoonotic clade rather than the human-specific clade. This study confirms that A. ceylanicum is endemic in the East Malaita region of this Pacific Island nation. The strain of the A. ceylanicum in this region can be shared among humans, dogs, and cats.

BACKGROUND: In Solomon Islands many people with Tuberculosis (TB) have challenges in accessing services because of socio-cultural, geographic and health service reasons, resulting in delays in TB treatment and low detection rates. The purpose of this project was to (i) develop a local language audio-visual resource (DVD) about TB (ii) share this resource with people in remote villages and (iii) evaluate the process and outcomes. METHODS: The project involved the development and evaluation of a DVD in local Kwaio language. The DVD included five short videos based on the Australian Respiratory Council TB Education Flipchart. The DVD also included short videos of: traditional music/chanting (ai'imae); drama that presented an allegory of TB; and a short documentary on the redevelopment of the local TB Ward. A mixed-methods approach evaluated changes in TB knowledge and investigated the impact of the DVD. RESULTS: The DVD was recorded and produced in March-June 2013 and screened in 41 villages and hamlets. The pre-post DVD survey was completed by 64% (255/400) of people who viewed the DVD in the villages. Pre-DVD survey responses showed a moderate to high knowledge about TB signs, symptoms and treatment but 76/255 (30%) stated TB was caused by sorcery and 85/255 (33%) incorrectly stated that TB medication should be stopped when a patient feels better. The post-DVD survey showed a significant increase in people in coastal villages reporting (i) a 3-week cough would trigger a medical assessment and (ii) TB is mainly spread through the air. Statements that TB is not caused by sorcery increased post-DVD in both coastal and mountain villages, however belief in sorcery in mountain villages remained high at 20/70 (29%). CONCLUSIONS: The local DVD resource was developed within local cultural understandings and oral traditions of Kwaio people. Using modern but accessible DVD technology generated a lot of interest about the disease and the stories. The project evaluation indicates that current delays in seeking treatment may be more due to socio-cultural and health service factors than awareness of the disease. Therefore the development of TB services, including TB education, which are culturally sensitive, remains important.

The mucosal cytokine response of healthy humans to parasitic helminths has never been reported. We investigated the systemic and mucosal cytokine responses to hookworm infection in experimentally infected, previously hookworm naive individuals from non-endemic areas. We collected both peripheral blood and duodenal biopsies to assess the systemic immune response, as well as the response at the site of adult worm establishment. Our results show that experimental hookworm infection leads to a strong systemic and mucosal Th2 (IL-4, IL-5, IL-9 and IL-13) and regulatory (IL-10 and TGF-ß) response, with some evidence of a Th1 (IFN-γ and IL-2) response. Despite upregulation after patency of both IL-15 and ALDH1A2, a known Th17-inducing combination in inflammatory diseases, we saw no evidence of a Th17 (IL-17) response. Moreover, we observed strong suppression of mucosal IL-23 and upregulation of IL-22 during established hookworm infection, suggesting a potential mechanism by which Th17 responses are suppressed, and highlighting the potential that hookworms and their secreted proteins offer as therapeutics for human inflammatory diseases.

PURPOSE: The purpose of this study was to test the cultural suitability of the WHOQOL-BREF Bangladesh for a rural village population in Bangladesh. METHODS: Participants (n = 35) were purposefully stratified for age, gender, education level and location from the Nilphamari district in northern rural Bangladesh. Cognitive interviews were conducted via an emergent probing method to identify issues with language and constructs within the tool. Data were collected through note taking and recordings of interviews. A coding framework was used to identify key issues with questions, which were analysed using SPSS version 19 and Chi-square analysis using a Fisher's exact test to determine statistically significant variances within the sample. RESULTS: Twenty-two of the 26 questions in the tool were found to be problematic. The majority of problems with questions related to wording and conceptual difficulties. The majority of participants found the tool to be overly formal. Issues with translation appeared to affect the interpretation of a number of questions, and some concepts in the tool were found to be irrelevant in a village setting. There were statistically significant differences between those of different educational backgrounds and between genders. CONCLUSIONS: The study found that the WHOQOL-BREF Bangladesh as it currently stands is not culturally or linguistically suitable for use within a rural northern Bangladeshi population.

BACKGROUND: Almost 32,000 people are living with human immunodeficiency virus (HIV) in Papua New Guinea (PNG). The primary route of transmission in this moderate prevalence setting is through heterosexual sex. Thus a gendered understanding of HIV is required to inform HIV prevention, treatment and care options. The aim of this review is to investigate understandings specifically about women and HIV in PNG and to identify gaps in the literature to inform future HIV research. METHODS: An integrative review of literature about women, HIV and PNG was conducted using a systematic search of online databases, including book chapters and grey literature. Prior to inclusion, literature was assessed using inclusion and exclusion criteria, and the Critical Appraisal Skills Programme (CASP) appraisal tool. Selected articles, book chapters and reports were coded and a constant comparative method of analysis used to construct a series of themes. RESULTS: The 26 articles, book chapters and reports included in the review were predominantly descriptive, original research (23/26 pieces of literature). Six themes were identified in the literature: economic, social and cultural factors (including mobility); gender issues (including violence against women); knowledge about HIV (including perception of risk of HIV); religious beliefs about HIV; women perceived as responsible for HIV transmission; and prevention of HIV. Literature about women and HIV in PNG is predominantly focussed upon women who sell sex, women as mothers or young women. Women are usually represented as either victims of HIV or responsible for transmitting HIV. Anthropological and social research has described the economic, social and cultural context along with the lived experience of HIV in PNG, but there is limited operations research or implementation research available. CONCLUSIONS: The literature reviewed has highlighted the importance of a gendered analysis of HIV prevention, care and treatment in PNG. There is an opportunity for operations, implementation and health systems research about HIV in PNG to shift research from description to action.

INTRODUCTION: Capacity building has been employed in international health and development sectors to describe the process of 'experts' from more resourced countries training people in less resourced countries. Hence the concept has an implicit power imbalance based on 'expert' knowledge. In 2011, a health research strengthening workshop was undertaken at Atoifi Adventist Hospital, Solomon Islands to further strengthen research skills of the Hospital and College of Nursing staff and East Kwaio community leaders through partnering in practical research projects. The workshop was based on participatory research frameworks underpinned by decolonising methodologies, which sought to challenge historical power imbalances and inequities. Our research question was, "Is research capacity strengthening a two-way process?" METHODS: In this qualitative study, five Solomon Islanders and five Australians each responded to four open-ended questions about their experience of the research capacity strengthening workshop and activities: five chose face to face interview, five chose to provide written responses. Written responses and interview transcripts were inductively analysed in NVivo 9. RESULTS: Six major themes emerged. These were: Respectful relationships; Increased knowledge and experience with research process; Participation at all stages in the research process; Contribution to public health action; Support and sustain research opportunities; and Managing challenges of capacity strengthening. All researchers identified benefits for themselves, their institution and/or community, regardless of their role or country of origin, indicating that the capacity strengthening had been a two-way process. CONCLUSIONS: The flexible and responsive process we used to strengthen research capacity was identified as mutually beneficial. Using community-based participatory frameworks underpinned by decolonising methodologies is assisting to redress historical power imbalances and inequities and is helping to sustain the initial steps taken to establish a local research agenda at Atoifi Hospital. It is our experience that embedding mutuality throughout the research capacity strengthening process has had great benefit and may also benefit researchers from more resourced and less resourced countries wanting to partner in research capacity strengthening activities.

INTRODUCTION: It is likely that calls for disaster medical assistance teams (DMATs) will continue in response to international disasters. OBJECTIVE: As part of a national survey, the present study was designed to evaluate leadership issues and use of standards in Australian DMATs. METHODS: Data was collected via an anonymous mailed survey distributed via State and Territory representatives on the Australian Health Protection Committee, who identified team members associated with Australian DMAT deployments from the 2004 Asian Tsunami disaster. RESULTS: The response rate for this survey was estimated to be approximately 50% (59/118). Most of the personnel had deployed to the Asian Tsunami affected areas. The DMAT members were quite experienced, with 53% (31/59) of personnel in the 45-55 years of age group. Seventy-five percent (44/59) of the respondents were male. Fifty-eight percent (34/59) of the survey participants had significant experience in international disasters, although few felt they had previous experience in disaster management (5%, 3/59). There was unanimous support for a clear command structure (100%, 59/59), with strong support for leadership training for DMAT commanders (85%, 50/59). However only 34% (20/59) felt that their roles were clearly defined pre-deployment, and 59% (35/59) felt that team members could be identified easily. Leadership was identified by two team members as one of the biggest personal hardships faced during their deployment. While no respondents disagreed with the need for meaningful, evidence-based standards to be developed, only 51% (30/59) stated that indicators of effectiveness were used for the deployment. CONCLUSIONS: In this study of Australian DMAT members, there was unanimous support for a clear command structure in future deployments, with clearly defined team roles and reporting structures. This should be supported by clear identification of team leaders to assist inter-agency coordination, and by leadership training for DMAT commanders. Members of Australian DMATs would also support the development and implementation of meaningful, evidence-based standards. More work is needed to identify or develop actual standards and the measures of effectiveness to be used, as well as the contents and nature of leadership training.

INTRODUCTION: Calls for disaster medical assistance teams (DMATs) are likely to continue in response to international disasters. OBJECTIVE: As part of a national survey, the present study was designed to evaluate the education and training of Australian DMATs. METHODS: Data were collected via an anonymous, mailed survey distributed via State and Territory representatives on the Australian Health Protection Committee, who identified team members associated with Australian DMAT deployments from the 2004 Southeast Asia tsunami disaster. RESULTS: The response rate for this survey was 50% (59/118). Most of the personnel had deployed to the tsunami-affected areas. The DMAT members were quite experienced, with 53% of personnel in the 45-55-year age group (31/59). Seventy-six percent of the respondents were male (44/58). While most respondents had not participated in any specific training or educationalprogram, any kind of relevant training was regarded as important in preparing personnel for deployment. The majority of respondents had experience in disasters, ranging from hypothetical exercises (58%, 34/59) to actual military (41%, 24/49) and non-governmental organization (32%, 19/59) deployments. Only 27% of respondents felt that existing training programs had adequately prepared them for deployment. Thirty-four percent of respondents (20/59) indicated that they had not received cultural awareness training prior to deployment, and 42% (25/59) received no communication equipment training. Most respondents felt that DMAT members needed to be able to handle practical aspects of deployments, such as training as a team (68%, 40/59), use of communications equipment (93%, 55/59), ability to erect tents/shelters (90%, 53/59), and use of water purification equipment (86%, 51/59). Most respondents (85%, 50/59) felt leadership training was essential for DMAT commanders. Most (88%, 52/59) agreed that teams need to be adequately trained prior to deployment, and that a specific DMAT training program should be developed (86%, 51/59). CONCLUSIONS: This study of Australian DMAT members suggests that more emphasis should be placed on the education and training. Prior planning is required to ensure the success of DMAT deployments and training should include practical aspects of deployment. Leadership training was seen as essential for DMAT commanders, as was team-based training. While any kind of relevant training was regarded as important for preparing personnel for deployment, Australian DMAT members, who generally are a highly experienced group of health professionals, have identified the need for specific DMAT training.

Archey's frogs (Leiopelma archeyi) are first on the list of evolutionarily distinct and globally endangered (EDGE) amphibians. Captive breeding is an important strategy for protection of the species, but programs are hampered by a lack of information on diseases present in wild and captive populations. Two novel nematodes (Koerneria sp. and Rhabditis sp.) were found separately in four captive Archey's frogs showing clinical signs of hemorrhagic purulent nasal discharge and weight loss. One of these frogs also had a novel protozoal infection (Tetrahymena) in the nasal cavity. Koerneria, Rhabditis, and Tetrahymena have not previously been reported in amphibians in New Zealand. One frog was treated successfully with oral moxidectin at 0.4 mg/kg for the nematode infection and topical metronidazole at 10 mg/kg for the protozoal infection. The clinical signs abated only after both infections were cleared. The second frog died before treatment could be established. The third and fourth frogs were found dead.

BACKGROUND: In resource-poor countries, such as Solomon Islands, the research agenda on health is often dominated by researchers from resource-rich countries. New strategies are needed to empower local researchers to set directions for health research. This paper presents a process which seeks to enable a local and potentially more equitable research agenda at a remote hospital in Solomon Islands. METHODS: In preparation for a health research capacity-building workshop at Atoifi Adventist Hospital, Malaita, Solomon Islands, a computer-based search was conducted of Solomon Islands public health literature. Using a levels-of-agreement approach publications were categorised as: a) original research, b) reviews, c) program descriptions and d) commentaries or discussion. Original research publications were further sub-categorised as: i) measurement, ii) descriptive research and iii) intervention studies. Results were reviewed with Solomon Islander health professionals in a focus group discussion during the health research workshop. Focus group participants were invited to discuss reactions to literature search results and how results might assist current or future local researchers to identify gaps in the published research literature and possible research opportunities at the hospital and surrounding communities. Focus group data were analysed using a grounded theory approach. RESULTS: Of the 218 publications meeting inclusion criteria, 144 (66%) were categorised as 'original research', 42 (19%) as 'commentaries/discussion', 28 (13%) as 'descriptions of programs' and 4 (2%) as 'reviews'. Agreement between three authors' (MRM, DM, AC) independent categorisation was 'excellent' (0.8 <κ). The 144 'original research' publications included 115 (80%) 'descriptive studies' (κ = 0.82); 19 (13%) 'intervention studies' (κ = 0.77); and 10 (7%) 'measurement studies'(κ = 0.80). Key themes identified in the focus group discussion challenged historical inequities evident from the literature review. These included: i) who has done/is doing research in Solomon Islands (largely non-Solomon Islanders); ii) when the research was done (research needs to keep up to date); iii) amount of published research (there should be more); iv) types of research (lack of intervention and operational research); v) value of published research (important); vi) gaps in published literature (need more research about nursing); vii) opportunities for research action (start small); viii) support required to undertake research at the hospital and in surrounding communities (mentoring and partnering with experienced researchers). CONCLUSIONS: A search and collaborative review of public health literature for Solomon Islands at a health research capacity building workshop has uncovered and challenged historical inequity in the conduct and access to public health research. Emerging Solomon Islander researchers at a remote hospital are now working to set priorities and strengthen local research efforts. These efforts have highlighted the importance of collaboration and mentoring for Solomon Islanders to instigate and implement public health research to improve the health of individuals and communities served by this remote hospital.
RESUMEN
BACKGROUND: One strategy available to public health officials during a pandemic is physician recommendations for isolation of infected individuals. This study was undertaken during the height of the Australian pandemic (H1N1) 2009 outbreak to measure self-reported willingness to comply with physician recommendations to stay home for seven days, and to compare responses for the current strain of pandemic influenza, avian influenza, seasonal influenza, and the common cold. METHODS: Data were collected as part of the Queensland Social Survey (QSS) 2009, which consisted of a standardized introduction, 37 demographic questions, and research questions incorporated through a cost-sharing arrangement. Four questions related to respondents' anticipated compliance with a physician's advice to stay home if they had a common cold, seasonal influenza, pandemic (H1N1) 2009 influenza or avian influenza were incorporated into QSS 2009, with responses recorded using a balanced Likert scale ranging from "very unlikely" to "very likely." Discordance between responses for different diseases was analysed using McNemar's test. Associations between demographic variables and anticipated compliance were analysed using Pearson's chi-square or chi-square for linear-by-linear association, and confirmed using multivariate logistic regression; p < 0.05 was used to establish statistical significance. RESULTS: Self-reported anticipated compliance increased from 59.9% for the common cold to 71.3% for seasonal influenza (p < .001), and to 95.0% for pandemic (H1N1) 2009 influenza and 94.7% for avian influenza (p < 0.001 for both versus seasonal influenza). Anticipated compliance did not differ for pandemic (H1N1) 2009 and avian influenza (p = 0.815). Age and sex were both associated with anticipated compliance in the setting of seasonal influenza and the common cold. Notably, 27.1% of health and community service workers would not comply with physician advice to stay home for seasonal influenza. CONCLUSIONS: Ninety-five percent of people report they would comply with a physicians' advice to stay home for seven days if they are diagnosed with pandemic (H1N1) 2009 or avian influenza, but only 71% can be expected to comply in the setting of seasonal influenza and fewer still can be expected to comply if they are diagnosed with a common cold. Sub-populations that might be worthwhile targets for public health messages aimed at increasing the rate of self-imposed isolation for seasonal influenza include males, younger people, and healthcare workers.

Amphibian chytridiomycosis is a fungal disease caused by the chytrid fungus Batrachochytrium dendrobatidis. It is arguably the most significant recorded infectious disease of any vertebrate class. The disease is reducing amphibian biodiversity across most continents and regions of the world, affecting the resilience of surviving populations and driving multiple species to extinction. It is now recognised by the World Organisation for Animal Health (OIE) as an internationally notifiable disease. Collaborative research in areas including the development of diagnostic assays, distribution and impact of the disease, and management (treatment and policy) has assisted in leading a paradigm shift in accepting infectious disease as a major factor influencing wildlife population stability and biodiversity.

The global trade in amphibians entails the transport of tens of millions of live animals each year. In addition to the impact harvesting wild animals can have on amphibian populations, there is mounting evidence that the emerging pathogens Batrachochytrium dendrobatidis and ranaviruses, the aetiological agents of chytridiomycosis and ranaviral disease, respectively, are spread through this trade. The link between these pathogens and amphibian declines and extinctions suggests that the epidemiological impact of the trade is significant and may negatively affect conservation and trade economics. Here we present a brief assessment of the volume of the global trade in live amphibians, the risk of individuals harboring infection, and information on the recent listing by the World Organization for Animal Health (OIE) of chytridiomycosis and ranaviral disease in the OIE Aquatic Animal Health Code. This listing made chytridiomycosis and ranaviral disease internationally notifiable diseases and thus subject to OIE standards, which aim to assure the sanitary safety of international trade in live amphibians and their products.

Spread of the amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd), which causes chytridiomycosis, has resulted in the extinction of frogs, but the distribution of Bd is incompletely known. We trialled the survey protocol for Bd by attempting to systematically map its distribution in Queensland, Australia. Bd was easily detected in known infected areas, such as the Wet Tropics and South East Queensland. It was not detected in bioregions adjacent to, but inland from or to the north of, infected regions: Einasleigh Uplands and Cape York adjacent to the infected Wet Tropics; and Brigalow Belt South adjacent to the infected South East Queensland bioregion. These regions where Bd was not detected have bordered infected regions for between 15 yr (in northern Queensland) and 30 yr (in southern Queensland), and so they define the geographical limits of Bd with regard to the long-term environmental conditions in Queensland. The Gulf Plains, a bioregion distant from infected bioregions, was also negative. Bd was confined to rainforest and bordering habitats, such as wet eucalypt forests. Infections were largely confined to permanent water-associated species, consistent with this being an important cause of this group having the greatest declines. Our data supports biogeographic climatic models that show much of inland and northern Australia to be too hot and dry to support Bd. As there is limited opportunity for Bd to spread further in Queensland, the priority for management is reducing the impact of Bd in affected populations and assisting frogs to disperse into their former distributions. Given that the survey protocol has been applied successfully in Australia it may be useful for mapping the distribution of Bd in other parts of the world.

INTRODUCTION: Atoifi Adventist Hospital is a 90 bed general hospital in East Kwaio, Malaita, Solomon Islands providing services to the population of subsistence villagers of the region. Health professionals at the hospital and attached College of Nursing have considerable human capacity and willingness to undertake health research. However they are constrained by limited research experience, training opportunities, research systems, physical infrastructure and access to resources. This brief commentary describes an 'Introduction to Health Research' workshop delivered at Atoifi Adventist Hospital in September 2009 and efforts to move from 'research workshop' to 'research work'. THE APPROACH: Using a participatory-action research approach underpinned by decolonising methodologies, staff from Atoifi Adventist Hospital and James Cook University (Queensland, Australia) collaboratively designed, implemented and evaluated a health research workshop. Basic health research principles and methods were presented using active learning methodologies. Following the workshop, Atoifi Adventist Hospital and Atoifi College of Nursing staff, other professionals and community members reported an increased awareness and understanding of health research. The formation of a local Research Committee, improved ethics review procedures and the identification of local research mentors followed the week long workshop. The workshop has acted as a catalyst for research activity, increasing structural and human resource capacity for local health professionals and community leaders to engage in research. DISCUSSION AND CONCLUSIONS: Participants from a variety of educational backgrounds participated in, and received benefit from, a responsive, culturally and linguistically accessible health research workshop. Improving health research systems at a remote hospital and aligning these with local and national research agendas is establishing a base to strengthen public health research and practice on Malaita, Solomon Islands.
RESUMEN
Worldwide, the numbers of travellers are increasing, with pharmacists having the potential to play a significant role in the provision of pre-travel health services to a large number of these travellers. However, studies examining whether pharmacists have the travel health knowledge to provide these services are limited. This study thus aimed to explore the travel health knowledge of Australian pharmacists. Surveys assessing pharmacists' knowledge of travel health were distributed through the Pharmaceutical Society of Australia and community pharmacies for self-completion. Overall, the travel health knowledge of participants was found to be good. However, although the majority of participants were aware of the common causes of morbidity and mortality in travel health, some slightly overestimated the prevalence of malaria and were less knowledgeable about the global distribution of some diseases. Most participants also demonstrated an ability to give appropriate advice on the management of traveller's diarhoea, the selection of appropriate items for inclusion in travel first aid kits, vaccinations, and malarial chemoprophylaxis for travellers visiting endemic areas. This study highlights that Australian pharmacists have the knowledge to deliver travel health advice, with the potential to improve both access and outcomes for travellers.
RESUMEN
BACKGROUND: Although hand dermatitis (HD) represents a frequent occupational issue for many health professionals, little is known about the prevalence and distribution of HD among veterinarians, particularly in Australia. AIM: We utilized a previously validated questionnaire survey to examine a cross-section of veterinarians from Queensland, Australia, to determine the prevalence of HD and its associated factors. METHOD: We conducted a questionnaire-based survey of HD, which was mailed to 1094 veterinarians registered with the Veterinary Surgeons Board of Queensland during 2006 (64.0% response rate). RESULTS: The overall prevalence rate of HD during this study was 15.9%. HD prevalence was significantly higher in those with current allergic disease (P < 0.001), among female veterinarians (P < 0.001), and those reporting latex allergy in the past 12 months (P < 0.001). CONCLUSIONS: Overall, this study suggests that HD may be more prevalent among veterinarians in Queensland than among their counterparts studied elsewhere. Veterinary practices may need to consider making non-latex gloves available or avoiding latex products wherever possible, particularly for their female staff. The importance of HD to the veterinary profession is predicted to increase as females begin to make up a greater proportion of registered veterinarians as result of a demographic shift.

Chytridiomycosis, a disease that has caused amphibian population declines globally and elevated many species of anurans to endangered or threatened status, has recently been declared an internationally notifiable disease. Batrachochytrium dendrobatidis (Bd), the amphibian chytrid fungus causing this disease, has not been previously reported in Korea or on mainland Asia. Thirty-six frog specimens representing 7 species were collected from the wild in South Korea and examined for Bd using standard PCR. Bd was detected in 14 (38.8%) samples from 3 species (Bufo gargarizans, Hyla japonica, and Rana catesbiana). Skin sections from all 14 PCR-positive frogs were examined using 2 staining techniques: haematoxylin and eosin (H&E) and Bd immunoperoxidase (IPX). In histological sections, zoosporangia were found in 6 frogs, with lower sensitivity for H&E (21%) than for IPX (46%). Intensity of infection, based on histopathology, was low in all frogs. These results confirm that Bd is present in South Korea and, hence, on the Asian mainland. Studies are urgently required to determine the impact of chytridiomycosis on Korean amphibians, and to map the distribution of Bd in Korea and other Asian mainland countries.
