RESUMO
BACKGROUND: Dengue is a public health problem in the Indo-Pacific countries. There are concerns over the facilitators and barriers to community engagement in health service research aimed at dengue control. The objective of his study was to identify and synthesize facilitators and barriers to community engagement in health service research aimed at dengue control. METHODOLOGY: The Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) checklist was used to perform this review. Health-related databases including PubMed, Ovid, and Google Scholar were searched for relevant studies. A consolidated framework with five domains was developed after undertaking a six-phase reflective thematic assessment of the data. RESULTS: Thirteen studies were identified, spanning eight low-and middle-income countries of the Indo-Pacific region including Cambodia, India, Indonesia, Myanmar, Philippines, Sri Lanka, Thailand, and Vietnam. The studies in this review covered the period from 2002 to 2021. A broad range of study designs and objectives were revealed across these 13 studies. An array of communities such as the local government, project-related health staff, local health services staff, community leaders, local communities/residences/general public, heads of households, community health volunteers, school teachers, and schoolchildren participated in these dengue related studies. The five Consolidated Framework for Implementation Research (CFIR) domains of 'intervention characteristics', 'inner setting', 'outer setting',' individual characteristics', and 'program implementations' were used to identify and describe barriers and facilitators. CONCLUSIONS: The findings indicate a range of barriers and facilitators to community engagement in dengue control in the selected LMIC in the Indo-Pacific countries. Future health services research on dengue control approaches should be carefully planned, methodologically constructed, aligned with community engagement principles, and involve considerable community participation at all stages of the research.

BACKGROUND: Achieving malaria elimination requires the targeting of the human reservoir of infection, including those patients with asymptomatic infection. The objective was to synthesise evidence on the accuracy of the rapid-onsite diagnostic tests (RDTs) and microscopy for the detection of asymptomatic malaria as part of the surveillance activities in Asian countries. METHODS: This was a meta-analysis of diagnostic test accuracy. Relevant studies that evaluated the diagnostic performance of RDTs and microscopy for detection of asymptomatic malaria were searched in health-related electronic databases. The methodological quality of the studies included was assessed using the QUADAS-2 tool. RESULTS: Ten studies assessing RDT and/or microscopy were identified. The diagnostic accuracies in all these studies were verified by PCR. Overall, the pooled sensitivities of RDT, as well as microscopy for detection of any malaria parasites in asymptomatic participants, were low, while their pooled specificities were almost ideal. For the detection of Plasmodium falciparum, pooled sensitivity by RDT (59%, 95%CI:16-91%) or microscopy (55%, 95%CI: 25-82%) were almost comparable. For detection of Plasmodium vivax, pooled sensitivity of RDT (51%, 95% CI:7-94%) had also the comparable accuracy of microscopy (54%, 95%CI,11-92%). Of note are the wide range of sensitivity and specificity. CONCLUSION: The findings of this meta-analysis suggest that RDTs and microscopy have limited sensitivity and are inappropriate for the detection of asymptomatic Plasmodium infections. Other methods including a combination of PCR-based strategies, Loop-Mediated Isothermal Amplification (LAMP) technique must be considered to target these infections, in order to achieve malaria elimination. However, more data is needed for the wide acceptance and feasibility of these approaches. Studies to explore the role of asymptomatic and sub-patent infections in the transmission of malaria are of critical importance and are recommended.

BACKGROUND: Globally, experiences of menarche and subsequent menstruation are embedded in social and cultural beliefs, norms and practices. Menarche is an important developmental milestone in sexual and reproductive health (SRH) for females. Menarche is intertwined with socio-cultural norms, beliefs and practices, which can impact on women's ability to manage menstruation with dignity. This paper reviews the social and cultural factors that affect women's ability to effectively manage their menstrual health and hygiene (MHH) in Pacific Island Countries and Territories (PICTs). METHODS: A scoping review was conducted following PRISMA scoping review guidelines and inclusion/exclusion criteria. An online search was conducted for peer-reviewed publications in Medline/OVID; Medline/PubMED; PsycINFO; CINAHL; Scopus and JSTOR, and Google Scholar. A search for grey literature was conducted in Google Scholar and websites of international and local organizations. Experts in the field also contributed additional references. Extracted data were summarised in an Excel spreadsheet. Searches were conducted between May and June, 2019, and then repeated in July, 2020. RESULTS: A total of 11 studies were included; 10 qualitative and one mixed methods study. Studies were conducted in Melanesian (n = 9), Polynesian (n = 1) and Micronesian (n = 1) PICTs. All 11 studies reported elements of societal and personal factors; ten studies reported evidence relating to interpersonal factors; nine studies reported elements relating to environmental factors; and two studies presented evidence linked to biological factors. Managing menstrual health with dignity is challenging for many women and girls because menstruation is associated with menstrual taboos and shame. CONCLUSION: This review found that the MHH experiences of women in PICTs are affected by social and cultural beliefs, norms and practices. Beliefs, norms and practices about menarche need to be incorporated in SRH planning, programs and education in order to be relevant to diverse village and urban settings.

BACKGROUND: Menarche, the first menstruation, is a significant developmental milestone for females. In Papua New Guinea (PNG), menarche is an important socio-cultural event marking transition from girlhood to womanhood. PNG is a culturally and linguistically diverse nation, with wide-ranging socio-cultural beliefs and practices around menarche. This study explored post-menarcheal women's understanding about body changes and menarche, preparation for menarche, and related cultural beliefs and practices at menarche. METHODS: A constructivist grounded theory study was conducted with 98 female participants who originated from four PNG provinces: Eastern Highlands Province; East Sepik Province; Milne Bay Province; and National Capital District. The participants were purposively and theoretically sampled, with 10 focus group discussions and six individual interviews conducted using a semi-structured interview guide for data collection. Focus group discussions and interviews were voice recorded and transcribed. Data were inductively analyzed using initial, intermediate and advanced coding, memos and constant comparative methods to develop a theoretical model that explains women's experiences at menarche. Interview participants also identified actions required to improve future experiences of girls at menarche in PNG. RESULTS: A grounded theory comprising the core category of 'Making of a Strong Woman' and four interconnecting categories ('Having Baby Sense'; 'Beginning of Learning'; 'Intensifying Learning'; and 'Achieving Womanhood') was constructed. 'Urban' and 'Rural' represented both geographical and socio-cultural intervening conditions that influence the experiences of girls at menarche. Experiences of young women at menarche were rooted in socio-cultural beliefs and practices. Women reported being physically and emotionally distressed and unprepared at onset of menarche. Mothers were considered important support, however, their ability to adequately prepare their daughters is limited by shame and secrecy. Despite these limitations, cultural practices at menarche provided an opportunity for intensive preparation of girls for womanhood. CONCLUSION: Limited pre-menarcheal awareness of the meaning of body changes and menarche of girls was linked to culture of shame and secrecy about open discussion on sexuality. However, traditional cultural practices provide an opportunity for collective support and focused learning for girls. Findings from this study have implications for broader sexual and reproductive health education programs in addressing menstrual health and hygiene in PNG, and the Pacific.

BACKGROUND: The significant contribution of community-based distribution (CBD) of family planning services and contraceptives to the uptake of contraceptives in hard-to-reach communities has resulted in the scaling-up of this approach in many Sub-Saharan countries. However, contextual factors need to be taken into consideration. For example, social network influence (e.g. spouse/partner, in-laws, and parents) on fertility decisions in many African and Asian societies is inevitable because of the social organisational structures. Hence the need to adapt CBD strategies to the social network context of a given society. METHODS: Data collection involved structured interviews from August 2018 to March 2019. Randomly selected respondents (n = 149) were recruited from four purposively selected health facilities in Lusaka district, Zambia. Respondents were screened for age (> 15 yrs.) and marital status. A mix of categorical and qualitative data was generated. The Statistical Package for Social Sciences (SPSS®24) was used to carry out descriptive analysis and tests of association (Fisher's exact) while Nvivo®12 was used to analyse the qualitative data using a deductive thematic approach. RESULTS: The results indicate that pre-marriage counselling (pre-MC) influences key elements of the husband-wife relationship (p > 0.005), namely; sexual relationship, inter-personal communication, assignation of roles and responsibilities, leadership and authority. These elements of the husband-wife relationship also affect how spouses/partners interact when making fertility decisions. More importantly, the majority (86%) of the respondents indicated having a continuing relationship with their marriage counsellors because of the need to consult them on marital issues. CONCLUSION: Marriage counsellors, though hardly reported in fertility studies, are important 'constituents' of the social network in the Zambian society. This is because marriage counsellors are trusted sources of information about marital issues and often consulted about family planning but perceived not to have the correct information about modern contraceptives. In this context, pre-MC offers a readily available, sustainable and culturally appropriate platform for disseminating accurate information about modern contraceptives provided in a private and personal manner. Therefore, the CBD strategy in Zambia can harness marriage counsellors by recruiting and training them as community agents.

BACKGROUND: Myanmar is a premalaria elimination country with artemisinin-resistant malaria. A strategy for transmission control is focused on vulnerable groups such as mobile and migrant populations (MMPs), and includes improving access to insecticide-treated bed nets in the Myanmar artemisinin resistance containment (MARC) zones using multisectoral approaches (MSA). METHODS: This narrative systematic review addressed MSAs targeted to MMPs in Myanmar for malaria prevention. We searched relevant studies in electronic databases and present the narrative findings in 4 domains: stakeholder groups, net coverage and utilization, social determinates, and facilitators/barriers. RESULTS: Nine studies were included. The review identified stakeholders involved in intersectoral collaboration. Net ownership was higher than utilization rates in the MARC zones and rates remained below the WHO recommended target of 100%. There was inadequate description of roles and responsibilities for implementation and on channels of communication within the partnerships and with the Government. CONCLUSIONS: Findings show that interventions to distribute treated bed nets were supported by the multiple stakeholders. Due to the design of the primary studies, analysis of the added value of intersectoral collaboration was limited. More attention must be paid to designing studies to document and evaluate the contributions and outcomes of intersectoral collaboration.

The Second International Symposium on One Health Research (ISOHR) was held in Guangzhou city, China on 23-24 November 2019. A transdisciplinary collaborative approach, One Health (OH), was the central theme of the symposium which brought together more than 260 experts, scholars and emerging researchers from human health, veterinary health, food safety, environmental health and related disciplines and sectors. More than 50 organizations including World Health Organization, Centers for Disease Control (USA), and Queensland Government (Australia) participated in the symposium. Scholars, experts and emerging researchers, policy-makers and practitioners in their respective fields delivered over 50 presentations at the symposium, highlighting the collective vulnerability to some of the emerging health challenges the region was combating. These included emerging infectious diseases, antimicrobial resistance, climate change, food safety and the growing burden of non-communicable diseases. The Pearl River Declaration, emanated from the symposium, called for establishing a One Health Cooperation Network in the Southeast Asia-Pacific region with a vision to strengthen regional health security through sharing each other's knowledge and experience, and making investments in workforce development, scientific innovations such as vaccine research and development, sharing epidemic intelligence, risk identification, risk communication and appropriate response measures against emerging health threats.

INTRODUCTION: Delivering health services and improving health outcomes of the 1.3 million people residing in northern Australia, a region spanning 3 million km2 across the three jurisdictions of Western Australia, Northern Territory and Queensland, presents specific challenges. This review addresses a need for systems level analysis of the issues influencing the coverage, quality and responsiveness of health services across this region by examining the available published literature and identifying key policy-relevant gaps. METHODS: A scoping review design was adopted with searches incorporating both peer-reviewed and grey literature (eg strategy documents, annual reports and budgets). Grey literature was predominantly sourced from websites of key organisations in the three northern jurisdictions, with peer-reviewed literature sourced from electronic database searches and reference lists. Key articles and documents were also contributed by health sector experts. Findings were synthesised and reported narratively using the WHO health system 'building blocks' to categorise the data. RESULTS: From the total of 324 documents and data sources included in the review following screening and eligibility assessment, 197 were peer-reviewed journal articles and 127 were grey literature. Numerous health sector actors across the north - comprising planning bodies, universities and training organisations, peak bodies and providers - deliver primary, secondary and tertiary healthcare and workforce education and training in highly diverse contexts of care. Despite many exemplar health service and workforce models in the north, this synthesis describes a highly fragmented sector with many and disjointed stakeholders and funding sources. While the many strengths of the northern health system include expertise in training and supporting a fit-for-purpose health workforce, health systems in the north are struggling to meet the health needs of highly distributed populations with poorly targeted resources and ill-suited funding models. Ageing of the population and rising rates of chronic disease and mental health issues, underpinned by complex social, cultural and environmental determinants of health, continue to compound these challenges. CONCLUSION: Policy goals about developing northern Australia economically need to build from a foundation of a healthy and productive population. Improving health outcomes in the north requires political commitment, local leadership and targeted investment to improve health service delivery, workforce stability and evidence-based strengthening of community-led comprehensive primary health care. This requires intersectoral collaboration across many organisations and the three jurisdictions, drawing from previous collaborative experiences. Further evaluative research, linking structure to process and outcomes, and responding to changes in the healthcare landscape such as the rapid emergence of digital technologies, is needed across a range of policy areas to support these efforts.

BACKGROUND: Following the scale-up of intervention efforts, malaria burden has decreased dramatically in Solomon Islands (SI). Submicroscopic and asymptomatic Plasmodium vivax infections are now the major challenge for malaria elimination in this country. Since children have higher risk of contracting malaria, this study investigated the dynamics of Plasmodium spp. infections among children including the associated risk factors of residual P. vivax burden. METHODS: An observational cohort study was conducted among 860 children aged 0.5-12 years in Ngella (Central Islands Province, SI). Children were monitored by active and passive surveillances for Plasmodium spp. infections and illness. Parasites were detected by quantitative real-time PCR (qPCR) and genotyped. Comprehensive statistical analyses of P. vivax infection prevalence, molecular force of blood stage infection (molFOB) and infection density were conducted. RESULTS: Plasmodium vivax infections were common (overall prevalence: 11.9%), whereas Plasmodium falciparum infections were rare (0.3%) but persistent. Although children acquire an average of 1.1 genetically distinct P. vivax blood-stage infections per year, there was significant geographic heterogeneity in the risks of P. vivax infections across Ngella (prevalence: 1.2-47.4%, p < 0.01; molFOB: 0.05-4.6/year, p < 0.01). Malaria incidence was low (IR: 0.05 episodes/year-at-risk). Age and measures of high exposure were the key risk factors for P. vivax infections and disease. Malaria incidence and infection density decreased with age, indicating significant acquisition of immunity. G6PD deficient children (10.8%) that did not receive primaquine treatment had a significantly higher prevalence (aOR: 1.77, p = 0.01) and increased risk of acquiring new bloodstage infections (molFOB aIRR: 1.51, p = 0.03), underscoring the importance of anti-relapse treatment. CONCLUSION: Residual malaria transmission in Ngella exhibits strong heterogeneity and is characterized by a high proportion of submicroscopic and asymptomatic P. vivax infections, alongside sporadic P. falciparum infections. Implementing an appropriate primaquine treatment policy to prevent P. vivax relapses and specific targeting of control interventions to high risk areas will be required to accelerate ongoing control and elimination activities.

Large-scale corporate projects, particularly those in extractive industries or hydropower development, have a history from early in the twentieth century of creating negative environmental, social, and health impacts on communities proximal to their operations. In many instances, especially for hydropower projects, the forced resettlement of entire communities was a feature in which local cultures and core human rights were severely impacted. These projects triggered an activist opposition that progressively expanded and became influential at both the host community level and with multilateral financial institutions. In parallel to, and spurred by, this activism, a shift occurred in 1969 with the passage of the National Environmental Policy Act in the United States, which required Environmental Impact Assessment (EIA) for certain types of industrial and infrastructure projects. Over the last four decades, there has been a global movement to develop a formal legal/regulatory EIA process for large industrial and infrastructure projects. In addition, social, health, and human rights impact assessments, with associated mitigation plans, were sequentially initiated and have increasingly influenced project design and relations among companies, host governments, and locally impacted communities. Often, beneficial community-level social, economic, and health programs have voluntarily been put in place by companies. These flagship programs can serve as benchmarks for community-corporate-government partnerships in the future. Here, we present examples of such positive phenomena and also focus attention on a myriad of challenges that still lie ahead.

This study explores conceptualisations and understandings of intimate relationships with young people in Samoa - an at-risk group experiencing high rates of intimate partner violence and alienation from sexual and relationship health promotion. Insights contribute to the immediate need to advance knowledge and practice around prevention with this group. An arts-based approach, which included a two-day interactive drama workshop coupled with follow-up, peer-led focus groups, was used to explore perceptions and understandings related to intimate relationships with 15 tertiary educated young people (nine female and six male) from across Samoa. Intersectionality informed the data collection and thematic analysis, examining participants' lived experiences and the ways multiple and intersecting identities interact within social and cultural systems to influence and inform these experiences. Outcomes highlight important tensions for young people, including the way in which age, gender, religion and sexuality interact with social hierarchies and power structures, socially prescribed gender norms, family structures and globalisation. This research provides insights that can inform the development of prevention strategies to address the root causes of intimate partner violence, building the knowledge and skills required for establishing intimate relationships free from violence with young people.

BACKGROUND: Malaria cases among mobile and migrant populations (MMPs) represent a large and important reservoir for transmission, if undetected or untreated. The objectives of this review were to identify which intersectoral actions have been taken and how they are applied to interventions targeted at the MMPs and also to assess the effect of interventions targeted to these special groups of population. RESULTS: A total of 36 studies met the inclusion criteria for this review. Numerous stakeholders were identified as involved in the intersectoral actions to defeat malaria amongst MMPs. Almost all studies discussed the involvement of Ministry of Health/Public Health (MOH/MOPH). The most frequently assessed intervention among the studies that were included was the coverage and utilization of insecticide-treated nets as personal protective measures (40.5%), followed by the intervention of early diagnoses and treatment of malaria (33.3%), the surveillance and response activities (13.9%) and the behaviour change communication (8.3%). There is a dearth of information on how these stakeholders shared roles and responsibilities for implementation, and about the channels of communication between-and-within the partners and with the MOH/MOPH. Despite limited details in the studies, the intermediate outcomes showed some evidence that the intersectoral collaborations contributed to improvement in knowledge about malaria, initiation and promotion of bed nets utilization, increased access to diagnosis and treatment in a surveillance context and contributed towards a reduction in malaria transmission. Overall, a high proportion of the targeted MMPs was equipped with correct knowledge about malaria transmission (70%, 95% CI 57-83%). Interventions targeting the use of bed nets utilization were two times more likely to reduce malaria incidence amongst the targeted MMPs (summary OR 2.01, 95% CI 1.43-2.6) than the non-users. The various intersectoral actions were often more vertically organized and not fully integrated in a systemic way within a given country or sub-national administrative setting. CONCLUSION: Findings suggest that interventions supported by the multiple stakeholders had a significant impact on the reduction of malaria transmission amongst the targeted MMPs. Well-designed studies from different countries are recommended to robustly assess the role of intersectoral interventions targeted to MMPs and their impact on the reduction of transmission.

Achieving a malaria-free world presents exciting scientific challenges as well as overwhelming health, equity, and economic benefits. WHO and countries are setting ambitious goals for reducing the burden and eliminating malaria through the "Global Technical Strategy" and 21 countries are aiming to eliminate malaria by 2020. The commitment to achieve these targets should be celebrated. However, the need for innovation to achieve these goals, sustain elimination, and free the world of malaria is greater than ever. Over 180 experts across multiple disciplines are engaged in the Malaria Eradication Research Agenda (malERA) Refresh process to address problems that need to be solved. The result is a research and development agenda to accelerate malaria elimination and, in the longer term, transform the malaria community's ability to eradicate it globally.

BACKGROUND: In a drug-resistant, malaria elimination setting like Western Cambodia, field research is essential for the development of novel anti-malarial regimens and the public health solutions necessary to monitor the spread of resistance and eliminate infection. Such field studies often face a variety of similar implementation challenges, but these are rarely captured in a systematic way or used to optimize future study designs that might overcome similar challenges. Field-based research staff often have extensive experience and can provide valuable insight regarding these issues, but their perspectives and experiences are rarely documented and seldom integrated into future research protocols. This mixed-methods analysis sought to gain an understanding of the daily challenges encountered by research field staff in the artemisinin-resistant, malaria elimination setting of Western Cambodia. In doing so, this study seeks to understand how the experiences and opinions of field staff can be captured, and used to inform future study designs. METHODS: Twenty-two reports from six field-based malaria studies conducted in Western Cambodia were reviewed using content analysis to identify challenges to conducting the research. Informal Interviews, Focus Group Discussions and In-depth Interviews were also conducted among field research staff. Thematic analysis of the data was undertaken using Nvivo 9® software. Triangulation and critical case analysis was also used. RESULTS: There was a lack of formalized avenues through which field workers could report challenges experienced when conducting the malaria studies. Field research staff faced significant logistical barriers to participant recruitment and data collection, including a lack of available transportation to cover long distances, and the fact that mobile and migrant populations (MMPs) are usually excluded from studies because of challenges in follow-up. Cultural barriers to communication also hindered participant recruitment and created unexpected delays. Field staff often paid a physical, emotional and financial cost, going beyond their duty in order to keep the study running. CONCLUSIONS: Formal monthly reports filled out by field study staff could be a key tool for capturing field study staff experiences effectively, but require specific report fields to encourage staff to outline their challenges and to propose potential solutions. Forging strong bonds with communities and their leaders may improve communication, and decrease barriers to participant recruitment. Study designs that make it feasible for MMPs to participate should be pursued; in addition to increasing the potential participant pool, this will ensure that the most malaria-endemic demographic is taken into account in research studies. Overlaps between clinical care and research create ethical dilemmas for study staff, a fact that warrants careful consideration. Lessons learned from study field staff should be used to create a set of locally-relevant recommendations to inform future study designs.

BACKGROUND: Pressure ulcers, also known as bed sores, pressure sores or decubitus ulcers develop as a result of a localised injury to the skin or underlying tissue, or both. The ulcers usually arise over a bony prominence, and are recognised as a common medical problem affecting people confined to a bed or wheelchair for long periods of time. Anabolic steroids are used as off-label drugs (drugs which are used without regulatory approval) and have been used as adjuvants to usual treatment with dressings, debridement, nutritional supplements, systemic antibiotics and antiseptics, which are considered to be supportive in healing of pressure ulcers. Anabolic steroids are considered because of their ability to stimulate protein synthesis and build muscle mass. Comprehensive evidence is required to facilitate decision making, regarding the benefits and harms of using anabolic steroids. OBJECTIVES: To assess the effects of anabolic steroids for treating pressure ulcers. SEARCH METHODS: In March 2017 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting. SELECTION CRITERIA: Published or unpublished randomised controlled trials (RCTs) comparing the effects of anabolic steroids with alternative treatments or different types of anabolic steroids in the treatment of pressure ulcers. DATA COLLECTION AND ANALYSIS: Two review authors independently carried out study selection, data extraction and risk of bias assessment. MAIN RESULTS: The review contains only one trial with a total of 212 participants, all with spinal cord injury and open pressure ulcers classed as stage III and IV. The participants were mainly male (98.2%, 106/108) with a mean age of 58.4 (standard deviation 10.4) years in the oxandrolone group and were all male (100%, 104/104) with a mean age of 57.3 (standard deviation 11.6) years in the placebo group. This trial compared oxandrolone (20 mg/day, administered orally) with a dose of placebo (an inactive substance consisting of 98% starch and 2% magnesium stearate) and reported data on complete healing of ulcers and adverse events. There was very low-certainty evidence on the relative effect of oxandrolone on complete ulcer healing at the end of a 24-week treatment period (risk ratio RR) 0.81, 95% confidence interval (CI) 0.52 to 1.26) (downgraded twice for imprecision due to an extremely wide 95% CI, which spanned both benefit and harm, and once for indirectness, as the participants were mostly male spinal cord injury patients). Thus, we are uncertain whether oxandrolone improves or reduces the complete healing of pressure ulcers, as we assessed the certainty of the evidence as very low.There was low-certainty evidence on the risk of non-serious adverse events reported in participants treated with oxandrolone compared with placebo (RR 3.85, 95% CI 1.12 to 13.26) (downgraded once for imprecision and once for indirectness, as the participants were mostly male spinal cord injury patients). Thus, the treatment with oxandrolone may increase the risk of non-serious adverse events reported in participants.There was very low-certainty evidence on the risk of serious adverse events reported in participants treated with oxandrolone compared with placebo (RR 0.54, 95% CI 0.25 to 1.17) (downgraded twice for imprecision due to an extremely wide 95% CI, which spanned both benefit and harm, and once for indirectness, as the participants were mostly male spinal cord injury patients). Of the five serious adverse events reported in the oxandrolone-treated group, none were classed by the trial teams as being related to treatment. We are uncertain whether oxandrolone increases or decreases the risk of serious adverse events as we assessed the certainty of the evidence as very low.Secondary outcomes such as pain, length of hospital stay, change in wound size or wound surface area, incidence of different type of infection, cost of treatment and quality of life were not reported in the included trial.Overall the evidence in this study was of very low quality (downgraded for imprecision and indirectness). This trial stopped early when the futility analysis (interim analysis) in the opinion of the study authors showed that oxandrolone had no benefit over placebo for improving ulcer healing. AUTHORS' CONCLUSIONS: There is no high quality evidence to support the use of anabolic steroids in treating pressure ulcers.Further well-designed, multicenter trials, at low risk of bias, are necessary to assess the effect of anabolic steroids on treating pressure ulcers, but careful consideration of the current trial and its early termination are required when planning future research.

BACKGROUND: There has been progress towards malaria elimination in the last decade. In response, WHO launched the Global Technical Strategy (GTS), in which vector surveillance and control play important roles. Country experiences in the Eliminating Malaria Case Study Series were reviewed to identify success factors on the road to elimination using a cross-case study analytic approach. METHODS: Reports were included in the analysis if final English language draft reports or publications were available at the time of analysis (Bhutan, Cape Verde, Malaysia, Mauritius, Namibia, Philippines, Sri Lanka, Turkey, Turkmenistan). A conceptual framework for vector control in malaria elimination was developed, reviewed, formatted as a matrix, and case study data was extracted and entered into the matrix. A workshop was convened during which participants conducted reviews of the case studies and matrices and arrived at a consensus on the evidence and lessons. The framework was revised and a second round of data extraction, synthesis and summary of the case study reports was conducted. RESULTS: Countries implemented a range of vector control interventions. Most countries aligned with integrated vector management, however its impact was not well articulated. All programmes conducted entomological surveillance, but the response (i.e., stratification and targeting of interventions, outbreak forecasting and strategy) was limited or not described. Indoor residual spraying (IRS) was commonly used by countries. There were several examples of severe reductions or halting of IRS coverage and subsequent resurgence of malaria. Funding and operational constraints and poor implementation had roles. Bed nets were commonly used by most programmes; coverage and effectiveness were either not measured or not articulated. Larval control was an important intervention for several countries, preventing re-introduction, however coverage and impact on incidence were not described. Across all interventions, coverage indicators were incomparable, and the rationale for which tools were used and which were not used appeared to be a function of the availability of funding, operational issues and cost instead of evidence of effectiveness to reduce incidence. CONCLUSIONS: More work is required to fill gaps in programme guidance, clarify the best methods for choosing and targeting vector control interventions, and support to measure cost, cost-effectiveness and cost-benefit of vector surveillance and control interventions.

BACKGROUND: In Cambodia, behaviour change communication (BCC) represents an integral component of malaria efforts aimed at fighting artemisinin resistant parasites and achieving elimination. The multi-pronged BCC interventions include interpersonal communication through village health volunteers (VHVs) and village malaria workers (VMWs), broadcasting malaria prevention, diagnosis and treatment messages via TV, radio and mobile broadcasting units (MBUs), distributing information education and communication (IEC) materials and introducing mobile malaria workers (MMWs) in endemic villages. METHODS: This was a cross sectional household survey using a stratified multi-stage cluster sampling approach, conducted in December 2012. A stratified multi-stage cluster sampling approach was used; 30 villages were selected (15 in each stratum) and a total of 774 households were interviewed. This survey aimed to assess the potential added effect of 'intense' BCC interventions in three Western provinces. Conducted 2 years after start of these efforts, 'non-intense' BCC (niBBC) interventions (e.g., radio or TV) were compared to "intense" BCC (iBBC) implemented through a set of interpersonal communication strategies such as VMWs, VHVs, mobile broadcasting units and listener viewer clubs. RESULTS: In both groups, the knowledge of the mode of malaria transmission was high (96.9 vs 97.2 %; p = 0.83), as well as of fever as a symptom (91.5 vs 93.5 %; p = 0.38). Knowledge of local risk factors, such as staying in the forest (39.7 vs 30.7 %; p = 0.17) or the farm (7.1 vs 5.1 %; p = 0.40) was low in both groups. Few respondents in either group knew that they must get tested if they suspected malaria (0.3 vs 0.1; p = 0.69). However, iBBC increased the discussions about malaria in the family (51.7 vs 35.8 %; p = 0.002) and reported prompt access to treatment in case of fever (77.1 vs 59.4 %; p < 0.01). CONCLUSION: The use of iBCC supported positive improvements in both attitudes and behaviours among the population with regard to malaria compared to mass media (niBCC) only. The significantly increase in people seeking treatment for fever in iBCC villages supports Objective Five of the Strategic Plan in the Cambodia Malaria Elimination Action Framework (2016-2020). Therefore, this study provides evidence for the planning and implementation of future BCC interventions to achieve the elimination of artemisinin resistant Plasmodium falciparum malaria.

BACKGROUND: Village malaria workers (VMWs) and mobile malaria workers (MMWs) are a critical component of Cambodia's national strategy to eliminate Plasmodium falciparum malaria by 2025. Since 2004, VMWs have been providing malaria diagnosis through the use of rapid diagnostic tests and free-of-charge artemisinin-based combination therapy in villages more than 5 km away from the closest health facility. They have also played a key role in the delivery of behaviour change communication interventions to this target population. This study aimed to assess the job performance of VMWs/MMWs, and identify challenges they face, which may impede elimination efforts. METHODS: A mixed-methods assessment was conducted in five provinces of western Cambodia. One hundred and eighty five VMW/MMW participants were surveyed using a structured questionnaire. Qualitative data was gathered through a total of 60 focus group discussions and 65 in-depth interviews. Data triangulation of the qualitative and quantitative data was used during analysis. RESULTS: Overall, VMWs/MMWs met or exceeded the expected performance levels (80 %). Nevertheless, some performance gaps were identified. Misconceptions regarding malaria transmission and prevention were found among workers. The recommended approach for malaria treatment, directly-observed treatment (DOT), had low implementation rates. Stock-outs, difficulties in reaching out to migrant and mobile populations, insufficient means of transportation and dwindling worker satisfaction also affected job performance. DISCUSSION: VMW/MMW job performance must be increased from 80 to 100 % in order to achieve elimination. In order to do this, it is recommended for the national malaria programme to eliminate worker malaria knowledge gaps. Barriers to DOT implementation and health system failures also need to be addressed. The VMW programme should be expanded on several fronts in order to tackle remaining performance gaps. Findings from this evaluation are useful to inform the planning of future activities of the programme and to improve the effectiveness of interventions in a context where artemisinin drug resistance is a significant public health issue.

BACKGROUND: As malaria transmission declines, it becomes more geographically focused and more likely due to asymptomatic and non-falciparum infections. To inform malaria elimination planning in the context of this changing epidemiology, local assessments on the risk factors for malaria infection are necessary, yet challenging due to the low number of malaria cases. METHODS: A population-based, cross-sectional study was performed using passive and active surveillance data collected in Aceh Besar District, Indonesia from 2014 to 2015. Malaria infection was defined as symptomatic polymerase chain reaction (PCR)-confirmed infection in index cases reported from health facilities, and asymptomatic or symptomatic PCR-confirmed infection identified in reactive case detection (RACD). Potential risk factors for any infection, species-specific infection, or secondary-case detection in RACD were assessed through questionnaires and evaluated for associations. RESULTS: Nineteen Plasmodium knowlesi, 12 Plasmodium vivax and six Plasmodium falciparum cases were identified passively, and 1495 community members screened in RACD, of which six secondary cases were detected (one P. knowlesi, three P. vivax, and two P. falciparum, with four being asymptomatic). Compared to non-infected subjects screened in RACD, cases identified through passive or active surveillance were more likely to be male (AOR 12.5, 95 % CI 3.0-52.1), adult (AOR 14.0, 95 % CI 2.2-89.6 for age 16-45 years compared to <15 years), have visited the forest in the previous month for any reason (AOR 5.6, 95 % CI 1.3-24.2), and have a workplace near or in the forest and requiring overnight stays (AOR 7.9, 95 % CI 1.6-39.7 compared to workplace not near or in the forest). Comparing subjects with infections of different species, differences were observed in sub-district of residence and other demographic and behavioural factors. Among subjects screened in RACD, cases compared to non-cases were more likely to be febrile and reside within 100 m of the index case. CONCLUSION: In this setting, risk of malaria infection in index and RACD identified cases was associated with forest exposure, particularly overnights in the forest for work. In low-transmission settings, utilization of data available through routine passive and active surveillance can support efforts to target individuals at high risk.

BACKGROUND: During the process of malaria elimination in the Greater Mekong Sub-region, mobile and migrant populations (MMPs) have been identified as the most at-risk demographic. An important sub-group of MMPs are seasonal workers, and this paper presents an evaluation of the reach and effectiveness of interventions tailored towards this group and was carried out as part of the Containment Project from 2009-11. METHODS: A mixed-methods study was conducted in Pailin Province in Western Cambodia. Three-hundred-and-four seasonal workers were surveyed using a structured questionnaire. Qualitative data were gathered through a total of eight focus group discussions and 14 in-depth interviews. Data triangulation of the qualitative and quantitative data was used during analysis. RESULTS: High mobility and low access of the target population to the interventions, as well as lack of social and anthropological research that led to implementation oversights, resulted in under-exposure of seasonal workers to interventions. Consequently, their reach and impact were severely limited. Some services, particularly Mobile Malaria Workers, had the ability to significantly impact key factors, such as risky behaviours among those they did reach. Others, like Listening and Viewing Clubs and mass media campaigns, showed little impact. CONCLUSIONS: There is potential in two of the interventions assessed, but high mobility and inadequate exposure of seasonal workers to these interventions must be considered in the development and planning of future interventions to avoid investing in low-impact activities and ensure that all interventions perform according to their maximum potential. This will be critical in order for Cambodia to achieve its aim of malaria elimination. The lessons learned from this study can be extrapolated to other areas of health care in Cambodia and other countries in order to reduce the gap between healthcare provided to MMPs, especially seasonal workers, and to the general population.
