The Special Programme for Research and Training in Tropical Diseases developed a massive open online course (MOOC) on implementation research with a focus on infectious diseases of poverty (IDPs) to ...reinforce the explanation of implementation research concepts through real case studies. The target MOOC participant group included public health officers, researchers and students. By reshaping institutions and building resilience in communities and systems, implementation research will allow progress towards universal health coverage and sustainable development goals. This study evaluates learners' knowledge in implementation research after completing the MOOC using anonymous exit survey responses. Of the almost 4000 enrolled in the two sessions of the MOOC in 2018, about 30% completed all five modules and the assessments, and were awarded certificates. The majority of the participants were early to mid-career professionals, under the age of 40, and from low- and middle-income countries. They were slightly more likely to be men (56%) with a Bachelor or a Master's degree. Participants were public health researchers (45%), public health officers (11%) or students (11%). On completion of the course, an exit survey revealed that 80.9% of respondents indicated significant improvement to strong and very strong implementation research knowledge. This evaluation clearly shows the usefulness of the MOOC on implementation research for reaching out to field researchers and public health practitioners who are facing problems in the implementation of control programmes in low- and middle-income countries.

IntroductionAn implementation research (IR) massive open online course (MOOC) was developed by the Special Programme for Research and Training in Tropical Diseases, to address the scarcity of ...training in low-income and middle-income countries in the field of IR. The Kirkpatrick model was used to evaluate the IR MOOC as it is widely applied for evaluation of training and educational programmes. The Kirkpatrick model evaluates training programmes on four levels: reaction, learning, behaviour and results. This paper addresses the impact of the IR MOOC on participants’ professional practice.MethodsFindings are based on analysis of survey and interview data collected 1.5–2 years after the conclusion of the two 2018 IR MOOC offerings. Of the 3858 MOC participants, 748 responded to the anonymous online survey and seven of these respondents were interviewed. All data are self-reported.ResultsThe IR MOOC was successful in enhancing the professional practice of participants and for their organisations. Over 40% reported modifying or implementing changes in their professional work. Respondents reported that participation in the MOOC had improved their ability to conduct IR, enhanced their professional profiles and increased their opportunities for collaboration, research and job promotion. Respondents stated that the MOOC had improved their work quality and productivity, and allowed them to contribute to research, initiate and develop professional collaborations and train others in IR. Respondents reported an increase in applying for grants and scholarships and presenting and publishing work on IR after participating in the MOOC. Barriers applying the knowledge gained from the IR MOOC were experienced, for example, due to a lack of funding and lack of support from colleagues, managers and organisations.ConclusionParticipants perceived that the IR MOOC was successful in its aims of delivering medium-term and long-term results in relation to their own and their organisations’ professional outcomes.
Cutaneous leishmaniasis has various outcomes, ranging from self-healing reddened papules to extensive open ulcerations that metastasise to secondary sites and are often resistant to standard ...therapies. In the case of L. guyanensis (L.g), about 5-10% of all infections result in metastatic complications. We recently showed that a cytoplasmic virus within L.g parasites (LRV1) is able to act as a potent innate immunogen, worsening disease outcome in a murine model. In this study, we investigated the immunophenotype of human patients infected by L.g and found a significant association between the inflammatory cytokine IL-17A, the presence of LRV1 and disease chronicity. Further, IL-17A was inversely correlated to the protective cytokine IFN-γ. These findings were experimentally corroborated in our murine model, where IL-17A produced in LRV1+ L.g infection contributed to parasite virulence and dissemination in the absence of IFN-γ. Additionally, IL-17A inhibition in mice using digoxin or SR1001, showed therapeutic promise in limiting parasite virulence. Thus, this murine model of LRV1-dependent infectious metastasis validated markers of disease chronicity in humans and elucidated the immunologic mechanism for the dissemination of Leishmania parasites to secondary sites. Moreover, it confirms the prognostic value of LRV1 and IL-17A detection to prevent metastatic leishmaniasis in human patients.

Neutrophils are rapidly recruited to the mammalian skin in response to infection with the cutaneous Leishmania pathogen. The parasites use neutrophils to establish the disease; however, the signals ...driving early neutrophil recruitment are poorly known. Here, we identified the functional importance of TLR2 signaling in this process. Using bone marrow chimeras and immunohistology, we identified the TLR2-expressing cells involved in this early neutrophil recruitment to be of nonhematopoietic origin. Keratinocytes are damaged and briefly in contact with the parasites during infection. We show that TLR2 triggering by Leishmania major is required for their secretion of neutrophil-attracting chemokines. Furthermore, TLR2 triggering by L. major phosphoglycans is critical for neutrophil recruitment to negatively affect disease development, as shown by better control of lesion size and parasite load in Tlr2–/– compared with wild-type infected mice. Conversely, restoring early neutrophil presence in Tlr2–/– mice through injection of wild-type neutrophils or CXCL1 at the onset of infection resulted in delayed disease resolution comparable to that observed in wild-type mice. Taken together, our data show a crucial role for TLR2-expressing nonhematopoietic skin cells in the recruitment of the first wave of neutrophils after L. major infection, a process that delays disease control.

Implementation research (IR) can play a critical role in the delivery of disease control interventions, particularly in low- and middle-income countries (LMICs). The growing demand for IR training ...has led to the development of a range of training programmes and university courses, the majority of which can not be accessed by learners in LMICs. This article reports on the evaluation of the massive open online course (MOOC) developed by the Special Programme for Research and Training in Tropical Diseases hosted by WHO on the topic of IR with a focus on infectious diseases of poverty. This study followed the Kirkpatrick Model to evaluate training programmes with a specific focus on post-training changes in behaviour.
MOOC participants were invited to take part in an anonymous online survey examining their knowledge of IR and how they applied it in their professional practice approximately 1-1.5 years after completing their course. The survey contained 43 open-ended, multiple choice and Likert-type questions. Descriptive statistics were calculated for the quantitative data and responses to the open-ended questions were thematically coded.
A total of 748 MOOC participants responded to the survey. The demographic profile of the survey respondents aligned with that of the MOOC participants, with nearly 70% of respondents originating from Africa. Responses to the quantitative and open-ended survey questions revealed that respondents' knowledge of IR had improved to a large extent as a result of the MOOC, and that they used the knowledge and skills gained in their professional lives frequently and had consequently changed their professional behaviour. Respondents most often cited the problem-solving aspect of IR as a substantial area of behavioral change influenced by participating in the MOOC.
These findings indicate that the MOOC was successful in targeting learners from LMICs, in strengthening their IR knowledge and contributing to their ability to apply it in their professional practice. The utility of MOOCs for providing IR training to learners in LMICs, where implementation challenges are encountered often, makes this platform an ideal standalone learning tool or one that could be combined with other training formats.

Neutrophils are rapidly and massively recruited to sites of microbial infection, where they can influence the recruitment of dendritic cells. Here, we have analyzed the role of neutrophil released ...chemokines in the early recruitment of dendritic cells (DCs) in an experimental model of Leishmania major infection. We show in vitro, as well as during infection, that the parasite induced the expression of CCL3 selectively in neutrophils from L. major resistant mice. Neutrophil-secreted CCL3 was critical in chemotaxis of immature DCs, an effect lost upon CCL3 neutralisation. Depletion of neutrophils prior to infection, as well as pharmacological or genetic inhibition of CCL3, resulted in a significant decrease in DC recruitment at the site of parasite inoculation. Decreased DC recruitment in CCL3(-/-) mice was corrected by the transfer of wild type neutrophils at the time of infection. The early release of CCL3 by neutrophils was further shown to have a transient impact on the development of a protective immune response. Altogether, we identified a novel role for neutrophil-secreted CCL3 in the first wave of DC recruitment to the site of infection with L. major, suggesting that the selective release of neutrophil-secreted chemokines may regulate the development of immune response to pathogens.

We solicited ideas for modifying the TDR fellowship using a crowdsourcing challenge. Then we used a mixed methods approach to evaluate texts submitted in response to the challenge. The qualitative ...analysis identified themes from eligible submissions. The quantitative analysis examined the mean score (1-10 scale) assigned to submitted ideas and also the number of eligible women applicants before (2014-7) and after (2018) implementing the top three ideas. We received 311 ideas on improving women's participation in this fellowship from 63 countries. Among all ideas, 282 (91%) were from women and 286 (92%) were from low- and middle-income countries (LMICs). Thirty-three (17%) ideas received an overall mean score of 7.0 or greater. The top three ideas included enhanced social media communication targeting women, improving career mentorship, and creating a nomination system to nudge women applicants. These ideas were implemented as part of the 2018 fellowship application cycle. The number of eligible women applicants increased from 11 in 2016 to 48 in 2018. The number of eligible men applicants increased from 55 in 2016 to 114 in 2018. Women represent 44% (8/18) of the 2018 cohort. This suggests that the challenge contest resulted in strong participation from women in LMICs. The three top ideas likely contributed to a greater number of women applicants to this mid-career fellowship. Further ways of enhancing women's participation in global health training are needed.

The EDCTP-TDR Clinical Research and Development Fellowship (CRDF) scheme has offered one-year clinical research training placements for early- and mid-career researchers from LMIC since 1999.
Using ...the results of a 2018 external evaluation of the CRDF, the current article aims to identify the principal benefits for the main stakeholders of the CRDF scheme as well as the main barriers to accessing these benefits.
Data analysis was derived from an external evaluation of the CRDF scheme. Based on a logical framework approach, data for the external evaluation was collected through document review, interviews, focus groups, and questionnaires collected from the main stakeholder groups. The evaluation was structured along six main themes: relevance, effectiveness, efficiency, impact, sustainability, and equity.
The current paper focuses on the expected benefits, unexpected benefits, and barriers to enjoying benefits of the scheme for key stakeholders.
Expected benefits were aligned with the development of clinical research competencies, which is the objective of the scheme. Unexpected benefits centred on transferable professional skills in scientific leadership and knowledge translation. Barriers mainly were found around engagement with home institutions and the return and reintegration of fellows following the training period.
Recommendations include further engagement with and support for home institutions and developing a formal framework for the development of transferable professional competencies, including leadership and knowledge transfer competencies.

The Special Programme for Research and Training in Tropical Diseases (TDR) co-sponsored by UNICEF, UNDP, World Bank and WHO has been supporting research capacity strengthening in low- and ...middle-income countries for over 40 years. In order to assess and continuously optimize its capacity strengthening approaches, an evaluation of the influence of TDR training grants on research career development was undertaken. The assessment was part of a larger evaluation conducted by the European Science Foundation. A comprehensive survey questionnaire was developed and sent to a group of 117 trainees supported by TDR who had completed their degree (masters or PhD) between 2000 and 2012; of these, seventy seven (77) responded. Most of the respondents (80%) rated TDR support as a very important factor that influenced their professional career achievements. The "brain drain" phenomenon towards high-income countries was particularly low amongst TDR grantees: the rate of return to their region of origin upon completion of their degree was 96%. A vast majority of respondents are still working in research (89%), with 81% of respondents having participated in multidisciplinary research activities; women engaged in multidisciplinary collaboration to a higher extent than men. However, only a minority of all have engaged in intersectoral collaboration, an aspect that would require further study. The post-degree career choices made by the respondents were strongly influenced by academic considerations. At the time of the survey, 92% of all respondents hold full-time positions, mainly in the public sector. Almost 25% of the respondents reported that they had influenced policy and practice changes. Some of the challenges and opportunities faced by trainees at various stages of their research career have been identified. Modalities to overcome these will require further investigation. The survey evidenced how TDR's research capacity grant programmes made a difference on researchers' career development and on south-south collaborations, by strengthening and localizing research capacity in lower income regions, and also showed there is more that needs to be done. The factors involved, challenges and lessons learnt may help donors and policy makers improve their future interventions with regard to designing capacity strengthening programmes and setting funding priorities.
