RESUMO
BACKGROUND: The life-threatening clinical manifestations of strongyloidiasis are preventable with early detection and effective treatment. The aim of this study was to assess if there was an increase to the number and proportion of persons tested for chronic strongyloidiasis, as a result of integrating Strongyloides stercoralis serology into the existing preventive health assessment system in four Aboriginal health services in endemic communities. METHODOLOGY: A prospective, longitudinal, before-and-after intervention study was conducted in four Aboriginal health services in remote endemically infected communities in the Northern Territory, Australia, from July 2012 to December 2016. The electronic patient information and recall systems enabled the integration of Strongyloides stercoralis serology into the adult preventive health assessment. Strongyloides reports for each health service were extracted half-yearly to examine the number and proportion of persons tested for chronic strongyloidiasis during the study and to measure the effect of the intervention. PRINCIPAL FINDINGS: The number and proportion of persons tested increased significantly during the study. From a total resident population of 3650 Indigenous adults over 15 years of age, 1686 persons (47.4%) were tested. The percentage of adults who had at least one serology test increased in all four health services to between 41% (446/1086) and 81.9% (172/210). Of the 1686 persons tested, 680 positive cases of chronic strongyloidiasis (40.3%) were identified. CONCLUSIONS/SIGNIFICANCE: This population health systems intervention increased the number and proportion of persons tested for chronic strongyloidiasis in four health services in endemically infected communities. This intervention is relevant to other health services with high-risk populations.

OBJECTIVE: Although soil-transmitted helminths (STH) are endemic in Solomon Islands, there are few recent reports on their prevalence. This study aimed to determine the prevalence of STH in residents of remote communities in Solomon Islands. METHODS: A cross-sectional convenience-sampled survey of residents of four adjacent villages in Malaita, Solomon Islands was performed in Atoifi and Na'au in April 2011 and in Abitona and Sifilo in April 2012. All residents older than one year were invited to participate, which involved providing a single sample of faeces examined using a modified Kato-Katz technique and completing a questionnaire that asked demographic and STH-related behaviour questions. RESULTS: The overall participation rate was 52.8%, with 402 participants comprising 49.8% males. Hookworm was the predominant STH with only a single case of trichuriasis found in Atoifi. The total prevalence of hookworm was 22.6% (95% confidence interval: 18.6-27.1); the prevalence of hookworm in Abitona, Na'au and Sifilo was 20.0%, 29.9% and 27.4%, respectively, whereas in Atoifi it was 2.3% (P < 0.001). Intensity was low in all villages. Although health behaviours differed significantly between Atoifi and the other three villages, the type of toilet used was the only significant association with hookworm. DISCUSSION: Residents of Atoifi have a relative freedom from STH compared to the other three villages. Rather than a region-wide morbidity control approach, a "one village at a time" approach aiming to eliminate STH and dealing with each village as a separate autonomous unit empowered to manage its own challenges may be a preferred option.

OBJECTIVE: To examine the correlation between HIV prevalence and male circumcision and other foreskin cutting practices across the four regions of Papua New Guinea (PNG). DESIGN: An ecological substudy using unique data from an interdisciplinary research programme to evaluate the acceptability, sociocultural context and public health impact of male circumcision for HIV prevention in PNG. METHODS: Published data describing (a) self-reported circumcision status by region from the 'Acceptability and Feasibility of Male Circumcision for HIV prevention in PNG' study and (b) HIV prevalence by region from PNG National Department of Health were used to correlate male circumcision and other foreskin cutting practices and HIV prevalence. Maps were constructed to visually represent variations across the four regions of PNG. RESULTS: Regions of PNG with the highest HIV prevalence had the lowest prevalence of male circumcision and other forms of foreskin cutting and vice versa. Male circumcision and dorsal longitudinal cuts were strongly associated with HIV prevalence and able to explain 99% of the observed geographical variability in HIV prevalence in PNG (p<0.01). CONCLUSIONS: The regional prevalence of HIV infection in PNG appears to be closely correlated with the regional distribution of male circumcision and dorsal longitudinal foreskin cuts. Further research is warranted to investigate causality of this correlation as well as the potential of dorsal longitudinal cuts to confer protection against HIV acquisition in heterosexual men.

RESUMO
BACKGROUND: The social and cultural positions of both researchers and research participants influence qualitative methods and study findings. In Papua New Guinea (PNG), as in other contexts, gender is a key organising characteristic and needs to be central to the design and conduct of research. The colonial history between researcher and participant is also critical to understanding potential power differences. This is particularly relevant to public health research, much of which has emerged from a positivist paradigm. This paper describes our critical reflection of flexible researcher responses enacted during qualitative research in PNG. METHODS: Led by a senior male HIV researcher from PNG, a male from a PNG university and a female from an Australian university conducted qualitative interviews about faith-based responses to HIV in PNG. The two researchers planned to conduct one-on-one interviews matching gender of participants and interviewer. However, while conducting the study, four participants explicitly requested to be interviewed by both researchers. This experience led us to critically consider socially and culturally situated ways of understanding semi-structured interviewing for public health research in Melanesia. RESULTS: New understandings about public health research include: (i) a challenge to the convention that the researcher holds more power than the research participant, (ii) the importance of audience in Melanesia, (iii) cultural safety can be provided when two people co-interview and (iv) the effect an esteemed leader heading the research may have on people's willingness to participate. Researchers who occupy insider-outsider roles in PNG may provide participants new possibilities to communicate key ideas. CONCLUSIONS: Our recent experience has taught us public health research methods that are gender sensitive and culturally situated are pivotal to successful research in Melanesia. Qualitative research requires adaptability and reflexivity. Public health research methods must continue to expand to reflect the diverse worldviews of research participants. Researchers need to remain open to new possibilities for learning.

BACKGROUND: Undertaking HIV research in the culturally diverse Pacific nation of Papua New Guinea (PNG) requires careful consideration of social, cultural and religious beliefs and practices. Here, we share a detailed description of culturally informed research processes and lessons learned from the first ever study undertaken on male circumcision for HIV prevention at a faith-based university in PNG. METHODS: Male and female staff and students at Pacific Adventist University were invited to complete an anonymous self-administered questionnaire, and/or participate in a semi-structured interview or focus group discussion. Male participants were invited for clinical examination. Results were collated and disseminated to the university community in gender segregated sessions. The study deliberately partnered with student leaders and centralised social, cultural, and religious paradigms. Student leaders were interviewed about their experience of partnering in sensitive health research. RESULTS: The student leaders reported that pre-existing relationships, cultural ties, gendered sensitivity and regular communication reinforced trust between researchers, student leaders and participants, and helped the success of the study. The amount of time, complex logistics and social and cultural relationships between single and married staff and students were highlighted as challenges. CONCLUSIONS: Partnering with regional student leaders to plan and implement the study gave a legitimate and immediate mechanism for involving PNG staff and students in this sensitive health research. Gendered research processes utilised established social and cultural structures and ensured the safety of participants; all of these factors contributed to the acceptability of the study. Capacity was strengthened in PNG and Australian researchers to undertake sensitive HIV research in PNG. The study demonstrated that it is possible to conduct sensitive sexual health research at a faith-based university in PNG.

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 AND AIMS: In remote Indigenous Australian communities measuring individual tobacco use can be confounded by cultural expectations, including sharing. We compared self-reported tobacco consumption with community-level estimates in Arnhem Land (Northern Territory). DESIGN AND METHODS: In a cross-sectional survey in three communities (population 2319 Indigenous residents, aged ≥16 years), 400 Indigenous residents were interviewed (206 men, 194 women). Eight community stores provided information about tobacco sold during the survey. To gauge the impact of 255 non-Indigenous residents on tobacco turnover, 10 were interviewed (five men, five women). Breath carbon monoxide levels confirmed self-reported smoking. Self-reported number of cigarettes smoked per day was compared with daily tobacco consumption per user estimated using amounts of tobacco sold during 12 months before the survey (2007-2008). 'Lighter smokers' (<10 cigarettes per day) and 'heavier smokers' (≥10 cigarettes per day) in men and women were compared. RESULTS: Of 400 Indigenous study participants, 305 (76%) used tobacco; four chewed tobacco. Of 301 Indigenous smokers, 177 (58%) provided self-reported consumption information; a median of 11-11.5 cigarettes per day in men and 5.5-10 cigarettes per day in women. Men were three times (odds ratio=2.9) more likely to be 'heavier smokers'. Store turnover data indicated that Indigenous tobacco users consumed the equivalent of 9.2-13.1 cigarettes per day; very similar to self-reported levels. Sixty per cent (=6/10) of non-Indigenous residents interviewed were smokers, but with little impact on tobacco turnover overall (2-6%). DISCUSSION AND CONCLUSIONS: Smoking levels reported by Indigenous Australians in this study, when sharing tobacco was considered, closely reflected quantities of tobacco sold in community stores.

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.
RESUMO
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.
RESUMO
BACKGROUND: This paper examines the specificity and sensitivity of a breath carbon monoxide (BCO) test and optimum BCO cutoff level for validating self-reported tobacco smoking in Indigenous Australians in Arnhem Land, Northern Territory (NT). METHODS: In a sample of 400 people (>/=16 years) interviewed about tobacco use in three communities, both self-reported smoking and BCO data were recorded for 309 study participants. Of these, 249 reported smoking tobacco within the preceding 24 hours, and 60 reported they had never smoked or had not smoked tobacco for >/=6 months. The sample was opportunistically recruited using quotas to reflect age and gender balances in the communities where the combined Indigenous populations comprised 1,104 males and 1,215 females (>/=16 years). Local Indigenous research workers assisted researchers in interviewing participants and facilitating BCO tests using a portable hand-held analyzer. RESULTS: A BCO cutoff of >/=7 parts per million (ppm) provided good agreement between self-report and BCO (96.0% sensitivity, 93.3% specificity). An alternative cutoff of >/=5 ppm increased sensitivity from 96.0% to 99.6% with no change in specificity (93.3%). With data for two self-reported nonsmokers who also reported that they smoked cannabis removed from the analysis, specificity increased to 96.6%. CONCLUSION: In these disadvantaged Indigenous populations, where data describing smoking are few, testing for BCO provides a practical, noninvasive, and immediate method to validate self-reported smoking. In further studies of tobacco smoking in these populations, cannabis use should be considered where self-reported nonsmokers show high BCO.
