The Global Health Security Agenda in an Age of Biosecurity

Historically, the Oval Office has been a leader in global health assistance. From the President’s Emergency Plan for AIDS Relief (PEPFAR) and the President’s Malaria Initiative (PMI) under the Bush Administration, to the Global Health Initiative launched by President Obama in 2009. However, unlike PEPFAR and PMI, the Global Health Initiative met an untimely end with the launch of a bold new global health measure by the Obama Administration: the Global Health Security Agenda (GHS Agenda). The GHS Agenda aims to “accelerate progress toward a world safe and secure from infectious disease threats” through a US-led diplomatic collaboration with 30 countries, international organizations, nongovernmental organizations, and public/private entities. The intertwining of global health and security follows a line of international agreements, including the revised International Health Regulations (2005), aimed at improving surveillance and response to public health emergencies of international concern. By mid-2012 however, only 22% of WHO member states had implemented the required core competencies. The GHS Agenda aims to address these global deficiencies in infectious disease preparedness. In doing so, the United States faces formidable obstacles including America’s lack of legal legitimacy in setting global norms, as well as the same domestic coordination difficulties that resulted in the dissolution of the Global Health Initiative, and the potential impediment of passing the President’s budget through a hostile Congress. While the securitization of global health has its criticisms, it also has the potential to be transformative, succeeding where international organizations have not always been able to, building a safer and healthier world

The Ebola Epidemic: A Public Health Emergency of International Concern

On August 8, 2014, the World Health Organization (WHO) Director-General Margaret Chan declared the West Africa Ebola crises a “public health emergency of international concern,” triggering powers under the 2005 International Health Regulations (IHR). The most affected West African states have attempted classic public health measures with varied success, including quarantine and isolation, social distancing, risk communication, and travel restrictions. These have involved a trade off between population health and human rights; sometimes to the disadvantage of both. At the same time, the countries’ health systems and human resources are fragile, impeding an effective response. Beyond the public health and humanitarian implications, this crisis has raised controversial ethical issues concerning the withholding or providing early access to investigational therapies, the preference given to foreign aid workers, and the disproportionate impact of Ebola on domestic health care workers. The WHO director-general’s declaration of a public health emergency of international concern underscores the urgency of a coordinated international response and the imperative of raising the health systems capacity of low-income states. However, the current outbreak demonstrates how global governance has suffered from a lack of binding international commitment to sustainable capacity building and technical assistance in low-income states

Development of practice principles for the management of ongoing suicidal ideation in young people diagnosed with major depressive disorder

Objectives: There is a lack of clear guidance regarding the management of ongoing suicidality in young people experiencing major depressive disorder. This study utilised an expert consensus approach in identifying practice principles to complement relevant clinical guidelines for the treatment of major depressive disorder in young people. The study also sought to outline a broad treatment framework for clinical intervention with young people experiencing ongoing suicidal ideation. Methods: In-depth focus groups were undertaken with a specialist multidisciplinary clinical team (the Youth Mood Clinic at Orygen Youth Health Clinical Program, Melbourne) working with young people aged 15–25 years experiencing ongoing suicidal ideation. Each focus group was audio recorded and transcribed verbatim using orthographic conventions. Principles of grounded theory and thematic analysis were used to analyse and code the resultant data. Results: The identified codes were subsequently synthesised into eight practice principles reflecting engagement and consistency of care, ongoing risk assessment and documentation, individualised crisis planning, engaging systems of support, engendering hopefulness, development of adaptive coping, management of acute risk, and consultation and supervision. Conclusions: The identified practice principles provide a broad management framework, and may assist to improve treatment consistency and clinical management of young people experiencing ongoing suicidal ideation. The practice principles may be of use to health professionals working within a team-based setting involved in the provision of care, even if peripherally, to young people with ongoing suicidal ideation. Findings address the lack of treatment consistency and shared terminology and may provide containment and guidance to multidisciplinary clinicians working with this at-risk group

Governance and Public Health Decision-Making During the COVID-19 Pandemic: A Scoping Review

Objective: We provide an in-depth understanding of how governance and decision-making during the COVID-19 pandemic has been empirically characterized in the literature to identify gaps in research and highlight areas that require further inquiry.Methods: We searched peer-reviewed publications using empirical data published between Jan 1, 2020 and Jan 31, 2022 in three electronic databases to examine the process of governance and decision-making during the COVID-19 pandemic. Two authors independently screened the records and 24 publications were extracted for the review.Results: Governance is analyzed by its level at national, sub-national, community and by its aspects of process, determinants and performance. While different methodological approaches are used, governance is conceptualized in four ways 1) characteristics and elements, 2) leadership, 3) application of power and 4) models or arrangements of governance.Conclusion: For future pandemic preparedness, there is a need for more empirical research using a unified conceptual approach to governance, which integrates decision-making processes and can guide governance structures and mechanisms across different countries and contexts. We call for more inclusivity in who performs the research on governance and where

The variability and reproducibility of whole genome sequencing technology for detecting resistance to anti-tuberculous drugs

Background: The emergence of resistance to anti-tuberculosis drugs is a serious and growing threat to public health. Next-generation sequencing is rapidly gaining traction as a diagnostic tool for investigating drug resistance in Mycobacterium tuberculosis to aid treatment decisions. However, there are few little data regarding the precision of such sequencing for assigning resistance profiles. Methods: We investigated two sequencing platforms (Illumina MiSeq, Ion Torrent PGM™) and two rapid analytic pipelines (TBProfiler, Mykrobe predictor) using a well characterised reference strain (H37Rv) and clinical isolates from patients with tuberculosis resistant to up to 13 drugs. Results were compared to phenotypic drug susceptibility testing. To assess analytical robustness individual DNA samples were subjected to repeated sequencing. Results: The MiSeq and Ion PGM systems accurately predicted drug-resistance profiles and there was high reproducibility between biological and technical sample replicates. Estimated variant error rates were low (MiSeq 1 per 77 kbp, Ion PGM 1 per 41 kbp) and genomic coverage high (MiSeq 51-fold, Ion PGM 53-fold). MiSeq provided superior coverage in GC-rich regions, which translated into incremental detection of putative genotypic drug-specific resistance, including for resistance to para-aminosalicylic acid and pyrazinamide. The TBProfiler bioinformatics pipeline was concordant with reported phenotypic susceptibility for all drugs tested except pyrazinamide and para-aminosalicylic acid, with an overall concordance of 95.3%. When using the Mykrobe predictor concordance with phenotypic testing was 73.6%. Conclusions: We have demonstrated high comparative reproducibility of two sequencing platforms, and high predictive ability of the TBProfiler mutation library and analytical pipeline, when profiling resistance to first- and second-line anti-tuberculosis drugs. However, platform-specific variability in coverage of some genome regions may have implications for predicting resistance to specific drugs. These findings may have implications for future clinical practice and thus deserve further scrutiny, set within larger studies and using updated mutation libraries

Associations Between Daily Wellness Behaviors and Outcomes among Medical Students

Objective: Explore which wellness behaviors have the greatest impact on wellbeing outcomes in medical students. Methods: A total of 213 medical students were enrolled in this study between June and September 2021. Participants completed a battery of online surveys, including demographic information, and 60-second nightly surveys on the WE-MD smartphone app, which assessed wellness-related indicators (exercise duration, sleep quality, nutrition quality, etc.) and wellbeing outcomes (mood, focus, stress, etc.). Results: 116 participants completed \u3e50% of nightly surveys between September 2021 and November 2021 and were included in the analysis. All wellness indicators were significantly associated with at least one wellness outcome. Quality of social interactions had the greatest relative positive association with wellbeing. Any amount of exercise, including 1-30 minutes, was significantly associated with improved wellbeing outcomes compared to no exercise. A lagged analysis separating indicators and outcomes by one day found wellbeing was only associated with limited sleep (\u3c 6 hours) and higher nutritional quality the day prior. Conclusion: This study provides substantial information on daily wellness behaviors and their relative impact on medical student wellbeing. Social interaction and exercise of any duration may be more important to wellbeing than previously recognized. Infrequently studied behaviors, including kindness, nutrition, and screen time, were also found to have significant associations with wellbeing. The numerous significant associations between behaviors and outcomes suggest a cumulative effect and point to the multifactorial nature of medical student wellbeing. This study may aid medical schools in developing high-impact initiatives and curricular changes that promote wellbeing for their students

Genome-wide diversity and differentiation in New World populations of the human malaria parasite Plasmodium vivax.

BACKGROUND: The Americas were the last continent colonized by humans carrying malaria parasites. Plasmodium falciparum from the New World shows very little genetic diversity and greater linkage disequilibrium, compared with its African counterparts, and is clearly subdivided into local, highly divergent populations. However, limited available data have revealed extensive genetic diversity in American populations of another major human malaria parasite, P. vivax. METHODS: We used an improved sample preparation strategy and next-generation sequencing to characterize 9 high-quality P. vivax genome sequences from northwestern Brazil. These new data were compared with publicly available sequences from recently sampled clinical P. vivax isolates from Brazil (BRA, total n = 11 sequences), Peru (PER, n = 23), Colombia (COL, n = 31), and Mexico (MEX, n = 19). PRINCIPAL FINDINGS/CONCLUSIONS: We found that New World populations of P. vivax are as diverse (nucleotide diversity π between 5.2 × 10-4 and 6.2 × 10-4) as P. vivax populations from Southeast Asia, where malaria transmission is substantially more intense. They display several non-synonymous nucleotide substitutions (some of them previously undescribed) in genes known or suspected to be involved in antimalarial drug resistance, such as dhfr, dhps, mdr1, mrp1, and mrp-2, but not in the chloroquine resistance transporter ortholog (crt-o) gene. Moreover, P. vivax in the Americas is much less geographically substructured than local P. falciparum populations, with relatively little between-population genome-wide differentiation (pairwise FST values ranging between 0.025 and 0.092). Finally, P. vivax populations show a rapid decline in linkage disequilibrium with increasing distance between pairs of polymorphic sites, consistent with very frequent outcrossing. We hypothesize that the high diversity of present-day P. vivax lineages in the Americas originated from successive migratory waves and subsequent admixture between parasite lineages from geographically diverse sites. Further genome-wide analyses are required to test the demographic scenario suggested by our data
