RESUMEN
Methods to measure the diversity and biological control impact of parasitoids for the control of spotted-wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) are being developed in support of biological control programs around the world. Existing methods to determine parasitism levels and parasitoid species composition focus on sampling D. suzukii within fresh and rotting fruit. However, many D. suzukii pupate in the soil or in dropped fruit, where additional parasitism could occur and where their parasitoids are thought to overwinter. Here we introduce a method for extracting parasitized D. suzukii puparia from the soil through a sieve and flotation system, allowing for effective collection of puparia, from which parasitoids can then be reared. Although the method considerably underestimates the absolute number of puparia in soil samples, it nonetheless yields a high number of puparia relative to sampling effort and provides a robust estimate of the relative abundance of puparia among samples. Using this method, we confirmed that at least 5 species of parasitoids, including some that have rarely been detected in past studies, overwinter in their immature stages inside D. suzukii puparia in south coastal British Columbia, Canada. The ability to sample puparia from the soil will lead to a more comprehensive view of both D. suzukii and parasitoid abundance throughout the season, help confirm parasitoid establishment following intentional releases, and provide a way to measure the diversity of parasitoid species and potential interactions among parasitoids (e.g., hyper- or klepto-parasitism) that may often occur on the soil surface.

BACKGROUND: Effective global health partnerships can strengthen and improve health and healthcare systems across the world; however, establishing and maintaining effective partnerships can be challenging. Principles of Partnerships have been developed to improve the quality and effectiveness of health partnerships. It is unclear how principles are enacted in practice, and current research has not always included the voices of low-income and middle-income country partners. This study aimed to explore how The Tropical Health and Education Trust's nine Principles of Partnership are enacted in practice, from the points of view of partners from low-income, middle-income and high-income countries, to help improve partnerships' quality and sustainability. METHODS: People who had been a part of previous and/or ongoing health partnerships were interviewed virtually. Participants were purposefully sampled and interviews were conducted using an appreciative inquiry approach. Audio recordings were transcribed and deductive framework analysis was conducted. RESULTS: 13 participants from 8 partnerships were interviewed. Six participants were based in the low-income or middle-income countries and seven in the UK. Key findings identified strategies that enacted 'successful' and 'effective' partnerships within the Principles of Partnerships. These included practical techniques such as hiring a project manager, managing expectations and openly sharing information about the team's expertise and aspirations. Other strategies included the importance of consulting behavioural science to ensure the partnerships consider longevity and sustainability of the partnership. DISCUSSION: Core principles to effective partnerships do not work in isolation of each other; they are intertwined and are complimentary to support equitable partnerships. Good communication and relationships built on trust which allow all partners to contribute equally throughout the project are core foundations for sustainable partnerships. Recommendations for established and future partnerships include embedding behavioural scientists/psychologists to support change to improve the quality and sustainability of health partnerships.

OBJECTIVE: To compare clinician documentation of sepsis for infective presentations in the ED against a formal sepsis pathway in the ED and to assess appropriateness of the initial parenteral antibiotic prescription for adult patients in ED. METHODS: A retrospective, clinical audit of adult patients who received at least one parenteral antibiotic in ED over a 10-week period in 2018. Documented initial clinical impression was compared with an approved sepsis pathway. Antibiotic appropriateness was assessed using National Antimicrobial Prescribing Survey definitions. Assessment was carried out by an infectious diseases pharmacist, with input from an infectious diseases physician. RESULTS: Two hundred and nineteen infective presentations were included in the analysis. There was a discordance between the initial documented clinical impression compared with the classification when a sepsis pathway was applied. An initial documented clinical impression of sepsis and septic shock was present in 38 (60.3%) of the presentations compared to 63 presentations when a formal sepsis pathway was applied as a screening tool. There was a significant difference in the proportion of patients in each diagnostic group (infection, sepsis and septic shock) according to documented clinical impression versus sepsis pathway classification (P = 0.0002). There were 386 prescriptions for antibiotics as part of the initial management. Antibiotic appropriateness for the initial prescription was assessed as 63.7% appropriate, 27.2% inappropriate and 9.1% not assessable. CONCLUSION: Our observations demonstrate that use of a formal sepsis pathway may improve the screening and early diagnosis of sepsis and septic shock and that there is a need for antibiotic prescribing guidance in the ED.

In recent years, health partnerships have shared infection prevention and control innovations between United Kingdom hospitals and Low-Middle-Income Countries. However, none had focused on antimicrobial stewardship (AMS), a core component of tackling antimicrobial resistance (AMR). This paper documents an effective approach to developing a program to increase AMS capacity in four African countries: Ghana, Tanzania, Uganda, and Zambia as part of the Commonwealth Partnerships for Antimicrobial Stewardship (CwPAMS) program. A systematic approach was applied to assess gaps in AMS interventions and inform the development of the CwPAMS program through deskbased assessments, including National Action Plans on AMR, online focus group meetings, and expert advisory group reviews. Twelve partnerships were selected for the CwPAMS program. AMS support tools were developed based on recommendations from the scoping, including an AMS checklist tool, a healthcare worker knowledge and attitudes questionnaire, and an antimicrobial prescribing app to support clinical decision-making. Training workshops on AMS were developed and delivered to volunteers in Africa and the UK using a train-the-trainer model. The tools and workshops facilitated capacity building for AMS through the generation and strengthening of knowledge, skills, commitment, structures, systems, and leadership among stakeholders in the UK and Africa. The overall average rating assigned to the program following independent evaluation using the Organisation for Economic Cooperation and Development Assistance Committee Evaluation Criteria was very good. The evaluation also highlighted that the majority of the HPs (75%) focused on AMS and/or improved prescribing practice; all HPs have developed and implemented AMS strategies, guidelines, and tools within their hospitals; and NHS staff were able to translate the knowledge and skills they had received early on in the program into clinical practice in response to COVID-19 challenges.
RESUMEN
BACKGROUND: Healthcare-associated infections (HAIs) are a major global public health problem, increasing the transmission of drug-resistant infections. In Africa, the prevalence of HAIs among all hospital inpatients is estimated to be between 3% and 15%, but outbreaks are infrequently reported. Failure to detect and/or report outbreaks can increase the risk of ongoing infections and recurrent outbreaks. METHODS: A search of the PubMed, Web of Science, Cochrane Library, and other outbreak databases was performed to identify published literature on bacterial HAI outbreaks in Africa (January 2009 to December 2018). Details of the outbreak characteristics, hospital environment, and the control measures implemented were extracted. RESULTS: Twenty-two studies published over the 10-year period were identified. These reported 31 distinct outbreaks and a total of 31 causative pathogens, including Klebsiella pneumoniae (six outbreaks, 19%), Staphylococcus aureus (six outbreaks, 19%), and Enterococcus (five outbreaks, 16%). Most outbreaks were reported from university (n = 8, 26%) and tertiary hospitals (n = 11, 55%), from South Africa (n = 9, 41%) and Tunisia (n = 4, 18%). Interventions to control the outbreaks were described in 27 (90%) outbreaks, and all instituted or recommended enhancing hand hygiene and education. CONCLUSIONS: Few facilities in Africa reported HAI outbreaks over the 10-year period, suggesting substantial under-detection and under-reporting. The quality and timeliness of reporting require improvement to ensure changes in public health practice.

Background: Antimicrobial resistance (AMR) is a growing public health threat in Africa. AMR prevention and control requires coordination across multiple sectors of government and civil society partners. Objectives: To assess the current role, needs, and capacities of CSOs working in AMR in Africa. Methods: We conducted an online survey of 35 CSOs working in 37 countries across Africa. The survey asked about priorities for AMR, current AMR-specific activities, monitoring practices, training needs, and preferences for sharing information on AMR. Further data were gathered on the main roles of the organisations, the length of time engaged in and budget spent on AMR-related activities, and their involvement in the development and implementation of National Action Plans (NAPs). Results were assessed against The Africa Centres for Disease Control and Prevention (Africa CDC) Framework for Antimicrobial Resistance (2018-2023). Results: CSOs with AMR-related activities are working in all four areas of Africa CDC's Framework: improving surveillance, delaying emergence, limiting transmission, and mitigating harm from infections caused by AMR microorganisms. Engagement with the four objectives is mainly through advocacy, followed by accountability and service delivery. There were limited monitoring activities reported by CSOs, with only seven (20%) providing an example metric used to monitor their activities related to AMR, and 27 (80%) CSOs reporting having no AMR-related strategy. Half the CSOs reported engaging with the development and implementation of NAPs; however, only three CSOs are aligning their work with these national strategies. Conclusion: CSOs across Africa are supporting AMR prevention and control, however, there is potential for more engagement. Africa CDC and other government agencies should support the training of CSOs in strategies to control AMR. Tailored training programmes can build knowledge of AMR, capacity for monitoring processes, and facilitate further identification of CSOs' contribution to the AMR Framework and alignment with NAPs and regional strategies.

BACKGROUND: Currently the health research system in Lao PDR is fragmented and largely donor led. Capacity among national public health institutes is limited to select priority research questions for funding. OBJECTIVE: The objective of this capacity building and practice-oriented study is to describe the process and outcome of the first National Health Research Agenda for Lao PDR and how the agenda contributes to institutional capacity of the Ministry of Health, in order to contribute to evidence-informed public health policy making. METHOD: This activity used a mixed-methods approach. The overall design is based on principles of the interactive Learning and Action approach and consists out of 6 phases: (1) identification of needs, (2) shared analysis and integration, (3) nation-wide prioritization of research domains, (4) exploring specific research questions, (5) prioritization of research avenues, (6) dialogue and planning for action. The process involved interviews with experts in health policy and research (n = 42), telephone-based survey with district, provincial and national health staff (n = 135), a two-round Delphi consultation with experts in health policy and research (n = 33), and a workshop with policymakers, researchers, international organisations and civil society (n = 45) were held to gather data and conduct shared analysis. RESULTS: 11 research domains were identified and prioritised: Health-seeking behaviour; Health system research; Health service provision; Mother and child health (MCH); Sexual & reproductive health; Health education; Non-communicable diseases (NCDs); Irrational drug use; Communicable diseases (CDs); Road traffic accidents; Mental health. Within these domains over 200 unique research questions were identified. CONCLUSION: Our approach led to a comprehensive, inclusive, public health agenda for Lao PDR to realise better informed health policies. Questions on the agenda are action-oriented, originating in a desire to understand the problem so that immediate improvements can be made. The agenda is used within the MoH as a tool to fund and approve research.
