Project description:BACKGROUND:Global health partnerships have expanded exponentially in the last two decades with Gavi, the Vaccine Alliance considered the model's pioneer and leader because of its vaccination programs' implementation mechanism. Gavi, relies on diverse domestic and international partners to carry out the programs in low- and middle-income countries under a partnership engagement framework (PEF). In this study, we utilized mixed methods to examine Mozambique's Gavi driven partnership network which delivered human papillomavirus (HPV) vaccine during the demonstration phase. METHODS:Qualitative tools gauged contextual factors, prerequisites, partner performance and practices while a social network analysis (SNA) survey measured the partnership structure and perceived added value in terms of effectiveness, efficiency and country ownership. Forty key informants who were interviewed included frontline Ministry of Health workers, Ministry of Education staff and supporting partner organization members, of whom 34 participated in the social network analysis survey. RESULTS:Partnership structure SNA connectivity measurement scores of reachability (100%) and average distance (2.5), were high, revealing a network of very well-connected HPV vaccination implementation collaborators. Such high scores reflect a network structure favorable for rapid and widespread diffusion of information, features necessary for engaging and handling multiple implementation scales. High SNA effectiveness and efficiency measures for structural holes (85%) and low redundancy (30%) coupled with high mean perceived effectiveness (97.6%) and efficiency (79.5%) network outcome scores were observed. Additionally, the tie strength average score of 4.1 on a scale of 5 denoted high professional trust. These are all markers of a collaborative partnership environment in which disparate institutions and organizations leveraged each entity's comparative advantage. Lower perceived outcome scores for country ownership (24%) were found, with participants citing the prominent role of several out-of-country partner organizations as a major obstacle. CONCLUSIONS:While there is room for improvement on the country ownership aspects of the partnership, the expanded, diverse and inclusive collaboration of institutions and organizations that implemented the Mozambique HPV vaccine demonstration project was effective and efficient. We recommend that the country adapt a similar model during national scale up of HPV vaccination.

Project description:Global health crises require coordination and collaboration among actors and global health agendas including health security, health promotion, and universal health coverage. This study investigated whether national public health institutes (NPHIs) unify agendas and actors, how this can be achieved, and what factors contribute to success. We conducted semi-structured interviews with 24 public health leaders from 18 countries in six WHO regions between 2019 and 2020. Respondents described how NPHIs bridge agendas reporting five strategies that institutes employ: serving as a trusted scientific advisor; convening actors across and within sectors; prioritizing transdisciplinary approaches; integrating public health infrastructures, and training that builds public health capacity. Findings also revealed five enabling factors critical to success: a strong legal foundation; scientific independence; public trust and legitimacy; networks and partnerships at global, national, and local levels; and stable funding. The Covid-19 pandemic underscores the urgency of securing scientific independence and promoting national institutes' responsiveness to public health challenges.

Project description:Molecular dynamics (MD) simulation is an important tool for understanding bio-molecules in microscopic temporal/spatial scales. Besides the demand in improving simulation techniques to approach experimental scales, it becomes more and more crucial to develop robust methodology for precisely and objectively interpreting massive MD simulation data. In our previous work [J Phys Chem B 114, 10266 (2010)], the trajectory mapping (TM) method was presented to analyze simulation trajectories then to construct a kinetic transition network of metastable states. In this work, we further present a top-down implementation of TM to systematically detect complicate features of conformational space. We first look at longer MD trajectory pieces to get a coarse picture of transition network at larger time scale, and then we gradually cut the trajectory pieces in shorter for more details. A robust clustering algorithm is designed to more effectively identify the metastable states and transition events. We applied this TM method to detect the hierarchical structure in the conformational space of alanine-dodeca-peptide from microsecond to nanosecond time scales. The results show a downhill folding process of the peptide through multiple pathways. Even in this simple system, we found that single common-used order parameter is not sufficient either in distinguishing the metastable states or predicting the transition kinetics among these states.

Project description:BackgroundGlobal health diplomacy (GHD) focuses on the actions taken by diverse stakeholders from different nations -governments, multilateral agents, and civil society- to phenomena that can affect population health and its determinants beyond national borders. Although the literature on conceptual advancements of GHD exists, empirical studies about how health becomes an issue of relevance for foreign policy are scarce. We present an analysis of the entry processes of health into the foreign policy and diplomatic domains in Mexico from the perspective of key informants of three different sectors.MethodsA purposive sample of high-rank representatives of three sectors involved in GHD was designed: Two from Health Sector (HS), four from Foreign Affairs Sector (FAS), and three from Non-governmental organizations (NGOs). Nine semi-structured interviews were conducted exploring the topics of: (1) Health concerns entering diplomatic and foreign policy; (2) Processes that allow actors to influence foreign policy and negotiation and; (3) Impact of multilateral negotiations on decision-making at the national level.ResultsOur analysis suggests that GHD in Mexico is hierarchically driven by the FAS and health concerns only enter foreign policy when they are relevant to national priorities (such as trade or security). HS possesses a lesser degree of influence in GHD, serving as an instance of consultation for the FAS when deciding on health-related issues at global meetings (i.e., World Health Assembly). NGOs resort to lobbying, advocacy, networking, and coalition-working practices with other sectors (academy, think-tanks) to prevent harmful impacts on local health from multilateral decisions and as a mean to compensate its power asymmetry for influencing GHD processes in relation to the government.ConclusionsGHD in Mexico occurs in a context of asymmetric power relationships where government actors have the strongest influence. However, NGOs' experience in raising awareness of health risks needs to be weighted by government decision-makers. This situation calls for capacity building on intersectoral communication and coordination to create formal mechanisms of GHD practices, including the professionalization and training on GHD among government agencies.

Project description:BackgroundThe World Health Organisation framed responsiveness, fair financing and equity as intrinsic goals of health systems. However, of the three, responsiveness received significantly less attention. Responsiveness is essential to strengthen systems' functioning; provide equitable and accountable services; and to protect the rights of citizens. There is an urgency to make systems more responsive, but our understanding of responsiveness is limited. We therefore sought to map existing evidence on health system responsiveness.MethodsA mixed method systemized evidence mapping review was conducted. We searched PubMed, EbscoHost, and Google Scholar. Published and grey literature; conceptual and empirical publications; published between 2000 and 2020 and English language texts were included. We screened titles and abstracts of 1119 publications and 870 full texts.ResultsSix hundred twenty-one publications were included in the review. Evidence mapping shows substantially more publications between 2011 and 2020 (n = 462/621) than earlier periods. Most of the publications were from Europe (n = 139), with more publications relating to High Income Countries (n = 241) than Low-to-Middle Income Countries (n = 217). Most were empirical studies (n = 424/621) utilized quantitative methodologies (n = 232), while qualitative (n = 127) and mixed methods (n = 63) were more rare. Thematic analysis revealed eight primary conceptualizations of 'health system responsiveness', which can be fitted into three dominant categorizations: 1) unidirectional user-service interface; 2) responsiveness as feedback loops between users and the health system; and 3) responsiveness as accountability between public and the system.ConclusionsThis evidence map shows a substantial body of available literature on health system responsiveness, but also reveals evidential gaps requiring further development, including: a clear definition and body of theory of responsiveness; the implementation and effectiveness of feedback loops; the systems responses to this feedback; context-specific mechanism-implementation experiences, particularly, of LMIC and fragile-and conflict affected states; and responsiveness as it relates to health equity, minority and vulnerable populations. Theoretical development is required, we suggest separating ideas of services and systems responsiveness, applying a stronger systems lens in future work. Further agenda-setting and resourcing of bridging work on health system responsiveness is suggested.

Project description:Antimicrobial resistance (AMR) decreases the effectiveness of antimicrobials to treat bacterial infections in humans and animals. The increased occurrence of AMR in bacterial population in humans, animals, and the environment requires the measures to combat a rising global health crisis. The aim of this research was to present current knowledge on AMR in a system map and to identify potential explanations of former identified variables significantly associated with AMR. This study applies a systems thinking approach and uses feedback loops to visualize the interconnections between human, animal, and environmental components in a circular AMR system map model. First, a literature review focusing on AMR and socioeconomic factors, wicked problem, and system change was carried out, which was then processed in a system map to conceptualize the present core challenges of AMR via feedback loops. Second, to investigate possible underlying values of the society and those that influence humans' behavior in the present AMR system, an iceberg model was established. Third, leverage points were assessed to estimate which kinds of interventions would have the greatest effect to mitigate AMR in the system. The present AMR system map implies the potential to identify and visualize important risk factors that are direct or indirect drivers of AMR. Our results show that the tool of system mapping, which interconnects animals, humans, and environment in one model, can approach AMR holistically and be used to assess potential powerful entry points for system wide interventions. This study shows that system maps are beneficial as a model to predict the relative effect of different interventions and adapt to rapidly changing environments in a complex world. Systems thinking is considered as a complementing approach to the statistical thinking, and further research is needed to evaluate the use of such tools for the development and monitoring of interventions.

Project description:BackgroundSince the advent of health user fees in low- and middle-income countries in the 1980s, the discourse of global health actors (GHAs) has changed to the disadvantage of this type of healthcare financing mechanism. The aim of the study was to identify and analyze the stance of GHAs in the debate on user fees.MethodsWe conducted documentary research using public documents published by and officially attributed to GHAs from 2005 to 2011. We categorized GHAs into four groups: intergovernmental organizations, international non-governmental organizations, government agencies, and working groups and networks. We then classified the GHAs according to their stance relative to the abolition of user fees, and conducted a thematic analysis of their discourse to understand the arguments used by each GHA to justify its stance.ResultsWe identified 56 GHAs, for which we analyzed 140 documents. Among them, 55% were in favor of the abolition of user fees or in favor of free care at the point of delivery. None of the GHAs stated that they were in favor of user fees; however, 30% did not take a stand. Only the World Bank declares that it is both in favor of user fees and in favor of free care at point of service. GHAs generally circumscribe their stance to specific populations (pregnant women, children under 5 years, etc.) or to specific health services (primary, basic, essential). Three types of arguments are used by GHAs to justify their stance: economic, moral and ethical, and pragmatic.ConclusionsThe principle of "user pays" seems to have fizzled. Production and dissemination of evidence, as well as certain advocacy networks, may have contributed to this change in discourse. However, GHAs should go a step further and translate their words into action, so that free healthcare at the point of delivery becomes a reality in low- and middle-income countries. They should provide technical and financial support to those countries that have chosen to implement user fee exemption policies, sometimes influenced by a GHA.

Project description:Elucidating the complete network of protein-protein interactions, or interactome, is a fundamental goal of the post-genomic era, yet existing interactome maps are far from complete. To increase the throughput and resolution of interactome mapping, methods for protein-protein interaction discovery by co-migration have been introduced. However, accurate identification of interacting protein pairs within the resulting large-scale proteomic datasets is challenging. Consequently, most computational pipelines for co-migration data analysis incorporate external genomic datasets to distinguish interacting from non-interacting protein pairs. The effect of this procedure on interactome mapping is poorly understood. Here, we conduct a rigorous analysis of genomic data integration for interactome recovery across a large number of co-migration datasets, spanning diverse experimental and computational methods. We find that genomic data integration leads to an increase in the functional coherence of the resulting interactome maps, but this comes at the expense of a decrease in power to discover novel interactions. Importantly, putative novel interactions predicted by genomic data integration are no more likely to later be experimentally discovered than those predicted from co-migration data alone. Our results reveal a widespread and unappreciated limitation in a methodology that has been widely used to map the interactome of humans and model organisms.

Project description:Global public health is increasingly being seen as a speciality field within the university education of public health. However, the exact meaning of global public health is still unclear, resulting in varied curricula and teaching units among universities. The contextual differences between high- and low- and middle-income countries, and the process of globalization need to be taken into account while developing any global public health course. Global public health and public health are not separable and global public health often appears as an extension of public health in the era of globalization and interdependence. Though global public health is readily understood as health of global population, it is mainly practiced as health problems and their solutions set within low- and middle-income countries. Additional specialist competencies relevant to the context of low- and middle-income countries are needed to work in this field. Although there can be a long list of competencies relevant to this broad topic, available literature suggests that knowledge and skills related with ethics and vulnerable groups/issues; globalization and its impact on health; disease burden; culture, society, and politics; and management are important.
