Avian influenza: Preparing for a pandemic

Abstract Since 1996 to 2006 there have been regular outbreaks of influenza. The genetics of virus plays an important role in its virulence mechanism. In this era of the impending threat on the influenza pandemic it is imperative that there be exchange of knowledge regarding the virus and its virulence. This article tries to address the above motive. An exhaustive review of literature has been provided regarding this viral threat.

Formal kinetics of H1N1 epidemic

<p>Abstract</p> <p>Background</p> <p>The formal kinetics of the H1N1 epidemic seems to take the form of an exponential curve. There is a good correlation between this theoretical model and epidemiological data on the number of H1N1-infected people. But this formal model leads to paradoxes about the dates when everyone becomes infected: in Mexico this will happen after one year, then in the rest of the world.</p> <p>Further implications of the formal model</p> <p>The general limitations of this formal kinetics model are discussed. More detailed modeling is examined and the implications are examined in the light of currently available data. The evidence indicates that not more than 10% of the population is initially resistant to the H1N1 virus.</p> <p>Conclusion</p> <p>We are probably only at the initial stage of development of the H1N1 epidemic. Increasing the number of H1N1-resistant people in future (e.g. due to vaccination) may influence the dynamics of epidemic development. At present, the development of the epidemic depends only on the number of people in the population who are initially resistant to the virus.</p

Removing barriers to emergency medicine point-of-care ultrasound: Illustrated by a roadmap for emergency medicine point-of-care ultrasound expansion in India

Point-of-care ultrasound (PoCUS) has a potentially vital role to play in emergency medicine (EM), whether it be in high-, medium-, or low-resourced settings. However, numerous barriers are present which impede EM PoCUS implementation nationally and globally: (i) lack of a national practice guideline or scope of practice for EM PoCUS, (ii) resistance from non-PoCUS users of ultrasound imaging (USI) and lack of awareness from those who undertake parallel or post-EM patient care, and (iii) heterogeneous pattern of resources available in different institutes and settings. When combined with the Indian Preconception and Prenatal Diagnostic Techniques (PCPNDT) Act, this has led to the majority of India’s 1.4 billion citizens being unable to access EM PoCUS. In order to address these barriers (globally as well as with specific application to India), this article outlines the three core principles of EM PoCUS: (i) the remit of the EM PoCUS USI must be well defined a priori, (ii) the standard of EM PoCUS USI must be the same as that of non-PoCUS users of USI, and (iii) the imaging performed should align with subsequent clinical decision-making and resource availability. These principles are contextualized using an integrated PoCUS framework approach which is designed to provide a robust foundation for consolidation and expansion across different PoCUS specialisms and health-care settings. Thus, a range of mechanisms (from optimization of clinical practice through to PoCUS educational reform) are presented to address such barriers. For India, these are combined with specific mechanisms to address the PCPNDT Act, to provide the basis for influencing national legislation and instigating an addendum to the Act. By mapping to the recent Lancet Commission publication on transforming access to diagnostics, this provides a global and cross-discipline perspective for the recommendations

International Health Security: A Summative Assessment by ACAIM Consensus Group

International health security (IHS) encompasses any natural or anthropogenic occurrence that can threaten the safety of human health and well-being. The American College of Academic International Medicine IHS Consensus Group (ACAIM-CG) developed a summative assessment highlighting the main issues that can impact IHS including emerging infectious diseases; chronic health conditions; bioterrorism; planetary changes (volcanic eruptions, earthquakes, wildfires, and climate change); nuclear incidents; information and cyber health; industrialization; globalization; pharmaceutical production; and communication platforms (social media). These concerns can directly and indirectly impact IHS both in the long and short term. When considering IHS, we aim to emphasize the utility of applying a predefined framework to effectively approach health security threats. This framework comprises of prevention, detection, assessment, reporting, response, addressing needs, and the perpetual repetition of the above cycle (inclusive of appropriate mitigation measures). It is hoped that this collective work will provide a foundation for further research within the redefined, expanded scope of IHS
