Comparative Study
Host adaptive immunity deficiency in severe pandemic influenza.
Pandemic A/H1N1/2009 influenza causes severe lower respiratory complications in rare cases. The association between host immune responses and clinical outcome in severe cases is unknown. ⋯ Our findings suggest an impaired development of adaptive immunity in the most severe cases of pandemic influenza, leading to an unremitting cycle of viral replication and innate cytokine-chemokine release. Interruption of this deleterious cycle may improve disease outcome.

The cornerstone of Canadian response to the pandemic H1N1 outbreak was the Canadian Pandemic Influenza Plan. The Plan was based on a moderate scenario, articulated around 7 pillars: surveillance, antiviral drugs, vaccines, public health measures, clinical care, communications, and research. This presentation provides an overview of Canada's response to pandemic H1N1. It presents the context (Who did what? How? …), what happened (focusing on pregnant women), addresses making decisions together, and includes some post-H1N1 reflections.

From the first case reports of pandemic influenza (H1N1) 2009 it was clear that a significant proportion of infected individuals suffered a primary viral pneumonia. The objective of this study was twofold; to assess the utility of the CURB-65 community acquired pneumonia (CAP) severity index in predicting pneumonia severity and ICU admission, and to assess the relative sensitivity of nasopharyngeal versus lower respiratory tract sampling for the detection of pandemic influenza (H1N1) CAP. ⋯ The CURB-65 score does not predict severe pandemic influenza (H1N1) 2009 CAP or need for ICU admission. Lower respiratory tract specimens should be collected when pandemic (H1N1) 2009 influenza CAP is suspected.

ReviewInfluenza pandemic preparedness and response: A review of legal frameworks in India.
the potential of pandemics to cause global destabilization calls for robust pandemic preparedness plans with supportive health legislation. Few international studies have investigated their national legal preparedness in case of a pandemic. This study reviews India's legal preparedness in the face of an epidemic. ⋯ india needs a critical mass of public health legislations to make impact and not police acts to control epidemics. This study aims to assist policy makers to create comprehensive pandemic preparedness plans, translating preparedness 'on paper' to 'in practice'.

The ongoing pandemic of 2009 H1N1 swine-origin influenza A has heightened the world's attention to the reality of influenza pandemics and their unpredictable nature. Currently, the 2009 H1N1 influenza strain appears to cause mild clinical disease for the majority of those infected. However, the risk of severe disease from this strain or other future strains remains an ongoing concern and is noted in specific patient populations. ⋯ Triage algorithms for resource allocation have been delineated in the general medical population. However, no current guidance considers the unique aspects of pregnant women and their unborn fetuses. An approach is suggested that may help guide facilities faced with these challenges.
