BACKGROUND Neuraminidase inhibitors were widely used during the 2009-10 influenza A H1N1 pandemic, but evidence for their effectiveness in reducing mortality is uncertain. We did a meta-analysis of individual participant data to investigate the association between use of neuraminidase inhibitors and mortality in patients admitted to hospital with pandemic(More)
BACKGROUND During the first wave of pandemic H1N1 influenza in 2009, most cases outside North America occurred in the UK. The clinical characteristics of UK patients hospitalised with pandemic H1N1 infection and risk factors for severe outcome are described. METHODS A case note-based investigation was performed of patients admitted with confirmed pandemic(More)
It is impossible to predict when the next pandemic of influenza will occur; however, it is almost 35 years since the last pandemic, and the longest inter-pandemic interval recorded with certainty is 39 years. The next pandemic virus is likely to emerge in southeast Asia, as have two of the last three pandemic viruses. Complete global spread is likely to(More)
BACKGROUND Assessment of the effect of influenza on populations, including risk of infection, illness if infected, illness severity, and consultation rates, is essential to inform future control and prevention. We aimed to compare the community burden and severity of seasonal and pandemic influenza across different age groups and study years and gain(More)
BACKGROUND Following emergence of naturally occurring oseltamivir-resistant influenza A(H1N1) viruses, a global observational investigation, the Influenza Resistance Information Study (IRIS; NCT00884117), was initiated in 2008 to study neuraminidase inhibitor (NAI) resistance and clinical outcome. METHODS Patients with influenza-like illness and/or(More)
BACKGROUND Effective antigen-sparing vaccines are needed to confront pandemic influenza. Whole-virion and oil-in-water adjuvanted vaccines are the most effective formulations against H5N1 avian influenza. We assessed the safety and immunogenicity in adults in the UK of pandemic H1N1 whole-virion vaccine and oil-in-water adjuvanted vaccine purchased by the(More)
OBJECTIVE The primary objective was to determine the proportion of babies who acquired passive immunity to A/H1N1v, born to mothers who accepted vaccination as part of the national vaccination programme while pregnant (during the second and/or third trimesters) against the novel A/H1N1v influenza virus (exposed group) compared with unvaccinated (unexposed)(More)
In the 1997-98 academic year, we conducted a longitudinal study of meningococcal carriage and acquisition among first-year students at Nottingham University, Nottingham, United Kingdom. We examined the dynamics of long-term meningococcal carriage with detailed characterization of the isolates. Pharyngeal swabs were obtained from 2,453 first-year students at(More)
AIMS To evaluate the role of surgical exploration and repair of the inguinal canal in athletes suspected of having a sports hernia. METHODS Thirty-five (34 males, 1 female) athletes with a suspected sports hernia underwent surgical exploration and inguinal hernia repair. After six months, all athletes were sent questionnaires to assess any improvement in(More)
Statins reduce cardiovascular mortality and related risks associated with pneumonia suggesting potentially beneficial use in influenza pandemics. We investigated the effect of current statin use on acute respiratory infections in primary care. Data from anonymized electronic medical records of persons aged 45 years were examined for statin use, chronic(More)
