Bartonella bacilliformis: a systematic review of the literature to guide the research agenda for elimination.

ABSTRACT:

Background

Carrion's disease affects small Andean communities in Peru, Colombia and Ecuador and is characterized by two distinct disease manifestations: an abrupt acute bacteraemic illness (Oroya fever) and an indolent cutaneous eruptive condition (verruga Peruana). Case fatality rates of untreated acute disease can exceed 80% during outbreaks. Despite being an ancient disease that has affected populations since pre-Inca times, research in this area has been limited and diagnostic and treatment guidelines are based on very low evidence reports. The apparently limited geographical distribution and ecology of Bartonella bacilliformis may present an opportunity for disease elimination if a clear understanding of the epidemiology and optimal case and outbreak management can be gained.

Methods

All available databases were searched for English and Spanish language articles on Carrion's disease. In addition, experts in the field were consulted for recent un-published work and conference papers. The highest level evidence studies in the fields of diagnostics, treatment, vector control and epidemiology were critically reviewed and allocated a level of evidence, using the Oxford Centre for Evidence-Based Medicine (CEBM) guidelines.

Results

A total of 44 studies were considered to be of sufficient quality to be included in the analysis. The majority of these were level 4 or 5 (low quality) evidence and based on small sample sizes. Few studies had been carried out in endemic areas.

Conclusions

Current approaches to the diagnosis and management of Carrion's disease are based on small retrospective or observational studies and expert opinion. Few studies take a public health perspective or examine vector control and prevention. High quality studies performed in endemic areas are required to define optimal diagnostic and treatment strategies.

Project description:BackgroundAttacks on health care in armed conflict, including those on health workers, facilities, patients and transports, represent serious violations of human rights and international humanitarian law. Information about these incidents and their characteristics are available in myriad forms: as published research or commentary, investigative reports, and within online data collection initiatives. We review the research on attacks on health to understand what data they rely on, what subjects they cover and what gaps exist in order to develop a research agenda going forward.Methods and findingsThis study utilizes a systematic review of peer-reviewed to identify and understand relevant data about attacks on health in situations of conflict. We identified 1479 papers published before January 1, 2020 using systematic and hand-searching and chose 45 articles for review that matched our inclusion criteria. We extracted data on geographical and conflict foci, methodology, objectives and major themes. Among the included articles, 26 focused on assessment of evidence of attacks, 15 on analyzing their impacts, three on the legal and human rights principles and one on the methods of documentation. We analyzed article data to answer questions about where and when attacks occur and are investigated, what types of attacks occur, who is perpetrating them, and how and why they are studied. We synthesized cross-cutting themes on the impacts of these attacks, mitigation efforts, and gaps in existing data.ConclusionRecognizing limitations in the review, we find there have been comparatively few studies over the past four decades but the literature is growing. To deepen the discussions of the scope of attacks and to enable cross-context comparisons, documentation of attacks on health must be enhanced to make the data more consistent, more thorough, more accessible, include diverse perspectives, and clarify taxonomy. As the research on attacks on health expands, practical questions on how the data is utilized for advocacy, protection and accountability must be prioritized.

Project description:BackgroundGlobally, there is renewed interest in and momentum for strengthening community health systems, as also emphasized by the recent Astana Declaration. Recent reviews have identified factors critical to successful community health worker (CHW) programs but pointed to significant evidence gaps. This review aims to propose a global research agenda to strengthen CHW programs.Methods and resultsWe conducted a search for extant systematic reviews on any intermediate factors affecting the effectiveness of CHW programs in February 2018. A total of 30 articles published after year 2000 were included. Data on research gaps were abstracted and summarized under headings based on predominant themes identified in the literature. Following this data gathering phase, two technical advisory groups comprised of experts in the field of community health-including policymakers, implementors, researchers, advocates and donors-were convened to discuss, validate, and prioritize the research gaps identified. Research gap areas that were identified in the literature and validated through expert consultation include selection and training of CHWs, community embeddedness, institutionalization of CHW programs (referrals, supervision, and supply chain), CHW needs including incentives and remuneration, governance and sustainability of CHW programs, performance and quality of care, and cost-effectiveness of CHW programs. Priority research questions included queries on effective policy, financing, governance, supervision and monitoring systems for CHWs and community health systems, implementation questions around the role of digital technologies, CHW preferences, and drivers of CHW motivation and retention over time.ConclusionsAs international interest and investment in CHW programs and community health systems continue to grow, it becomes critical not only to analyze the evidence that exists, but also to clearly define research questions and collect additional evidence to ensure that CHW programs are effective, efficient, equity promoting, and evidence based. Generally, the literature places a strong emphasis on the need for higher quality, more robust research.
