Easy access to evidence-based information on COVID-19 within an infodemic has been a challenging task. Chatbots have been introduced in times of emergency, when human resources are stretched thin and individuals need a user-centered resource. The World Health Organization Regional Office for Europe and UNICEF (United Nations Children's Fund) Europe and Central Asia came together to build a chatbot, HealthBuddy+, to assist country populations in the region to access accurate COVID-19 information in the local languages, adapted to the country context. Working in close collaboration with thematic technical experts, colleagues and counterparts at the country level allowed the project to be tailored to a diverse range of subtopics. To ensure that HealthBuddy+ was relevant and useful in countries across the region, the 2 regional offices worked closely with their counterparts in country offices, which were essential in partnering with national authorities, engaging communities, promoting the tool, and identifying the most relevant communication channels in which to embed HealthBuddy+. Over the past 2 years, the project has expanded from a web-based chatbot in 7 languages to a multistream, multifunction chatbot available in 16 regional languages, and HealthBuddy+ continues to expand and adjust to meet emerging health emergency needs.
El concepto de Salud Global implica conectar la salud humana, animal y medioambiental para combatir la expansión de las infecciones y el preocupante aumento de las bacterias resistentes a los antibióticos.
Medical journal publishing has changed dramatically over the past decade. The shift from print to electronic distribution altered the industry’s economic model. This was followed by open access mandates from funding organizations and the subsequent imposition of article processing charges on authors. The medical publishing industry is large and while there is variation across journals, it is overall highly profitable. As journals have moved to digital dissemination, advertising revenues decreased and publishers shifted some of the losses onto authors by way of article processing charges. The number of open access journals has increased substantially in recent years. The open access model presents an equity paradox; while it liberates scientific knowledge for the consumer, it presents barriers to those who produce research. This emerging “pay-to-publish” system offers advantages to authors who work in countries and at institutes with more resources. Finally, the medical publishing industry represents an unusual business model; the people who provide both the content and the external peer review receive no payment from the publisher, who generates revenue from the content. The very unusual economic model of this industry makes it vulnerable to disruptive change. The economic model of medical publishing is rapidly evolving and this will lead to disruption of the industry. These changes will accelerate dissemination of science and may lead to a shift away from lower-impact journals towards pre-print servers.
Covid infections are putting people at higher risk of diabetes, strokes, heart disease and other long-term illnesses - but experts warn it may be decades before the full impact is known.

We still have much to learn about many aspects of COVID-19 — including its lingering health effects and the mechanics of its endless mutations — but we do know one thing: we can’t let our guard down.
Millions of people are suffering from Long COVID or post-acute sequelae of COVID-19 (PASC). Several biological factors have emerged as potential drivers of PASC pathology. Some individuals with PASC may not fully clear the coronavirus SARS-CoV-2 after acute infection. Instead, replicating virus and/or viral RNA—potentially capable of being translated to produce viral proteins—persist in tissue as a ‘reservoir’. This reservoir could modulate host immune responses or release viral proteins into the circulation. Here we review studies that have identified SARS-CoV-2 RNA/protein or immune responses indicative of a SARS-CoV-2 reservoir in PASC samples. Mechanisms by which a SARS-CoV-2 reservoir may contribute to PASC pathology, including coagulation, microbiome and neuroimmune abnormalities, are delineated. We identify research priorities to guide the further study of a SARS-CoV-2 reservoir in PASC, with the goal that clinical trials of antivirals or other therapeutics with potential to clear a SARS-CoV-2 reservoir are accelerated. Proal and colleagues review the evidence for long-term persistence of coronavirus SARS-CoV-2 in tissues of infected individuals and discuss how this viral reservoir may contribute to the pathogenesis of post-acute sequelae of COVID-19 (PASC).
The determination of an adequate sample size is a prerequisite for any research programme. A study concluded on the basis of a smaller sample size than required is termed an ‘underpowered study’ and its reliability is questionable. Such a study ma

The persistent and pervasive gender gap in health care is a fact backed by data, science, and evidence. This editorial aims to describe some of the challenges that continue to persist. Many of the strategies outlined can be implemented both locally and nationally to effect meaningful change and work toward closing the existing gender gap in health care.

Background: The COVID-19 outbreak has revealed a high demand for timely surveillance of pandemic developments. Google Trends (GT), which provides freely available search volume data, has been proven to be a reliable forecast and nowcast measure for public health issues. Previous studies have tended to use relative search volumes from GT directly to analyze associations and predict the progression of pandemic. However, GT’s normalization of the search volumes data and data retrieval restrictions affect the data resolution in reflecting the actual search behaviors, thus limiting the potential for using GT data to predict disease outbreaks. Objective: This study aimed to introduce a merged algorithm that helps recover the resolution and accuracy of the search volume data extracted from GT over long observation periods. In addition, this study also aimed to demonstrate the extended application of merged search volumes (MSVs) in combination of network analysis, via tracking the COVID-19 pandemic risk. Methods: We collected relative search volumes from GT and transformed them into MSVs using our proposed merged algorithm. The MSVs of the selected coronavirus-related keywords were compiled using the rolling window method. The correlations between the MSVs were calculated to form a dynamic network. The network statistics, including network density and the global clustering coefficients between the MSVs, were also calculated. Results: Our research findings suggested that although GT restricts the search data retrieval into weekly data points over a long period, our proposed approach could recover the daily search volume over the same investigation period to facilitate subsequent research analyses. In addition, the dynamic time warping diagrams show that the dynamic networks were capable of predicting the COVID-19 pandemic trends, in terms of the number of COVID-19 confirmed cases and severity risk scores. Conclusions: The innovative method for handling GT search data and the application of MSVs and network analysis to broaden the potential for GT data are useful for predicting the pandemic risk. Further investigation of the GT dynamic network can focus on noncommunicable diseases, health-related behaviors, and misinformation on the internet.
