Corrected and Republished: Global Health Diplomacy Fingerprints on Human Security.

Human security is a concept that challenges the traditional notion of national security by placing the 'human' as the central referent of security instead of the 'state.' It is a concept that encompasses health and well-being of people and prioritizes their fundamental freedoms and basic livelihoods by shielding them from acute socioeconomic threats, vulnerabilities and stress. The epicenter of "health security" is located at the intersection of several academic fields or disciplines which do not necessarily share a common theoretical approach. Diverse players in the "health security" domain include practitioners in such fields as security studies, foreign policy, international relations, development theory, environmental politics and the practices of the United Nations system and other multilateral bodies like the World Health Organization (WHO) and the Pan American Health Organization (PAHO). Improvements in health are not only dependent on continued commitments to enhance the availability of healthcare and to strengthen disease prevention systems; they are very much enhanced by that intersection between global security and global health. What is emerging is global health diplomacy paradigm that calls for strengthening of core capacities in the public health and foreign policy arenas aimed at advancing human security through the strengthening of global health diplomacy practices. Human security in its broadest sense embraces far more than the absence of violence and conflict. It encompasses human rights, good governance, access to education and health care, and ensuring that each individual has opportunities and devices to fulfill his or her potential. Every step in this direction is a step towards reducing poverty, achieving growth and preventing conflict. Freedom from want, freedom from fear and the freedom of future generations to inherit a natural environment - these are the interrelated building blocks of human- and therefore national security.

Port of Spain Summit Declaration as a successful outcome of global health diplomacy in the Caribbean region: a systematic review.

Background: The Caribbean region, with a population of around 17 million, has the highest burden of chronic noncommunicable diseases (NCDs) in the region of the Americas. It is estimated that diabetes and hypertension has an economic impact of around 5%-8% of the gross domestic product of the region. The purpose of this study was to explore and understand how global health diplomacy contributed to the evolution of a collective Caribbean regional summit declaration to address the epidemic of NCDs. Methods: A systematic review was conducted, and all the major databases such as MEDLINE, PubMed, EMBASE, Scopus, Web of Science, EBSCO, Global Health database and other available policy documents from various sources were screened. All articles available from 1910-2018were extracted. From the total of 3223 titles, after filtering, the search narrowed down to 28full texts that are included in this study. Policy documents and articles related to NCDs, global health diplomacy, and the Port of Spain Declaration (POSD) were the focused themes. Results: The Caribbean region showed significant commitment to the prevention and control of NCDs through its united voice and commitment since 2001. The successful rounds of negotiations for regional health have led to the formulation of the 15- point multisectoral POSD "Uniting to Stop the Epidemic of Chronic NCDs." This was the first Summit in the world where the Heads of Government focused on prevention and control of NCDs with a clear road map for policy implementation, collaboration, and collective action. This regional summit declaration gained global attention and resulted in the United Nations Political Declaration on the Prevention and Control of NCDs and as WHO Global Action Plan for the Prevention and control of NCDs 2013-2020. Conclusion: There is enormous scope for this evolving area of Global Health Diplomacy in addressing the future challenges of health security.

Global health diplomacy, health and human security: The ascendancy of enlightened self-interest.

The political, social, economic, and security implications of health-related issues such as emerging infectious diseases or the epidemic of Non Communicable Diseases offer a rare opportunity for professionals in foreign policy and international relations to engage with the health arena and at the same time for global health experts to enter into and intersect with the domain of diplomacy. The aim of this review is to understand and explore the concepts of global health diplomacy (GHD), health security, and human security. For this narrative review, a literature search was done in PubMed, Scopus, and EBSCO for the "global health diplomacy," "health security," and "human security," and full-texts were reviewed. The recent outbreaks of Ebola in West Africa and Zika in South America are pertinent examples of the nature of the human security crisis and the imminent and severe threat posed to human life across the globe as a result of these epidemics. The Commission on Human Security defines human security as the protection of the vital core of all human lives from critical and pervasive threats. We highlight the ways in which health has now become an issue of national security/global concern and also how GHD can aid in the development of new bilateral or multilateral agreements to safeguard the health and security of people in our globalized world. The paper provides a prospective about, and overview of, health and human security that essentially emphasizes the growing interlinkages between global health, diplomacy, and foreign policy.

An audit of half-count myocardial perfusion imaging using resolution recovery software.

INTRODUCTION: The Nuclear Medicine Software Quality Group of the Institute of Physics and Engineering in Medicine has conducted a multicentre, multivendor audit to evaluate the use of resolution recovery software from several manufacturers when applied to myocardial perfusion data with half the normal counts acquired under a variety of clinical protocols in a range of departments. The objective was to determine whether centres could obtain clinical results with half-count data processed with resolution recovery software that were equivalent to those obtained using their normal protocols. MATERIALS AND METHODS: Sixteen centres selected 50 routine myocardial perfusion studies each, from which the Nuclear Medicine Software Quality Group generated simulated half-count studies using Poisson resampling. These half-count studies were reconstructed using resolution recovery and the clinical reports compared with the original reports from the full-count data. A total of 769 patient studies were processed and compared. RESULTS: Eight centres found only a small number of clinically relevant discrepancies between the two reports, whereas eight had an unacceptably high number of discrepancies. There were no significant differences in acquisition parameters between the two groups, although centres finding a high number of discrepancies were more likely to perform both rest and stress scans on normal studies. CONCLUSION: Half of the participating centres could potentially make use of resolution recovery to reduce the administered activity for myocardial perfusion scans without changing their routine acquisition protocols. The other half could consider adjusting the reconstruction parameters used with their resolution recovery software if they wish to use reduced activity successfully.

UK audit of quantification of left-ventricular function using gated myocardial perfusion imaging.

PURPOSE: The aim of the study was to evaluate UK-wide interinstitutional reproducibility of left-ventricular functional parameters, end-systolic volume, end-diastolic volume and ejection fraction, obtained from gated myocardial perfusion imaging (GMPI) studies using technetium-99m-labelled radiopharmaceuticals. The study was carried out by the UK Institute of Physics and Engineering in Medicine Nuclear Medicine Software Quality Group. MATERIALS AND METHODS: Ten anonymized clinical GMPI studies, five with normal perfusion and five with perfusion defects, were made available in DICOM and proprietary formats for download and through manufacturers' representatives. Two of the studies were duplicated in order to assess intraoperator repeatability, giving a total of 12 studies. Studies were made available in 8 and 16 frames/cycle. RESULTS: A total of 58 institutions across England, Scotland, Wales and Northern Ireland participated in this study using six different computer packages. Studies were processed at centres using their normal clinical computers and software. The overall mean±SD ejection fraction for all centres was 58.5±3%; the mean end-diastolic volume was 114±12 ml and the mean end-systolic volume was 54±6 ml. The results were affected by the number of frames per cycle and by the postprocessing computer package, but not by the reconstruction filter in the filtered back-projection. CONCLUSION: Calculation of functional parameters from GMPI using technetium-99m-labelled radiopharmaceuticals is reliable and shows limited variability across the UK.

An audit of manufacturers' implementation of reconstruction filters in single-photon emission computed tomography.

AIM: The Nuclear Medicine Software Quality Group of the Institute of Physics and Engineering in Medicine has conducted an audit to compare the ways in which different manufacturers implement the filters used in single-photon emission computed tomography. The aim of the audit was to identify differences between manufacturers' implementations of the same filter and to find means for converting parameters between systems. METHODS: Computer-generated data representing projection images of an ideal test object were processed using seven different commercial nuclear medicine systems. Images were reconstructed using filtered back projection and a Butter worth filter with three different cutoff frequencies and three different orders. RESULTS: The audit found large variations between the frequency-response curves of what were ostensibly the same filters on different systems. The differences were greater than could be explained simply by different Butter worth formulae. Measured cutoff frequencies varied between 40 and 180% of that expected. There was also occasional confusion with respect to frequency units. CONCLUSION: The audit concluded that the practical implementation of filtering, such as the size of the kernel, has a profound effect on the results, producing large differences between systems. Nevertheless, this work shows how users can quantify the frequency response of their own systems so that it will be possible to compare two systems in order to find filter parameters on each that produce equivalent results. These findings will also make it easier for users to replicate filters similar to other published results, even if they are using a different computer system.
