MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27797595
Resumo: INTRODUCTION: Over the last century several influenza outbreaks have traversed the globe, most recently the influenza A(H1N1) 2009 pandemic. On each occasion, a highly contagious, virulent pathogen has emerged, leading to significant morbidity and mortality amongst those affected. Areas covered: Early antiviral therapy and supportive care is the mainstay of treatment. Treatment should be started as soon as possible and not delayed for the results of diagnostic testing. Whilst oseltamivir is (mais)

Resumo: Flu infection, caused by the influenza virus, constitutes a serious threat to human lives worldwide. A rapid, sensitive and specific diagnosis is urgently needed for point-of-care treatment and to control the rapid spread of this disease. In this study, an ultrasensitive, rapid and specific localized surface plasmon resonance (LSPR)-induced immunofluorescence nanobiosensor has been developed for the influenza virus based on a gold nanoparticle (AuNP)-induced quantum dot (QD) fluorescence si (mais)

Resumo: Influenza virus infections (IVI) may pose a vital threat to immunocompromised patients such as those suffering from malignancies, but specific data on epidemiology and outcome in these patients are scarce. In this study, we collected data on patients with active cancer or with a history of cancer, presenting with documented IVI in eight centres in Germany. Two hundred and three patients were identified, suffering from haematological malignancies or solid tumours; 109 (54 %) patients had ac (mais)

Resumo: There was an increase in severe and fatal influenza cases in Greece during the 2011-2015 post-pandemic period. To investigate causality, we determined neuraminidase (NA) inhibitor susceptibility and resistance-conferring NA and hemagglutinin (HA) mutations in circulating influenza type A viruses during the pandemic (2009-2010) and post-pandemic periods in Greece. One hundred thirty-four influenza A(H1N1)pdm09 and 95 influenza A(H3N2) viruses submitted to the National Influenza Reference Lab (mais)

Resumo: Pneumonia remains a leading cause of morbidity and mortality in developing countries. Comprehensive surveillance data are needed to review the prevention and control strategies. We conducted active surveillance of acute lower respiratory infections among children aged <2 years hospitalized at two hospitals of Islamabad, Pakistan. Viral etiology was determined using real-time PCR on respiratory specimens collected during March 2011-April 2012. The overall mean age was 7.83 ± 5.25 months (mais)

Resumo: We herein report the pulmonary histopathological findings of an autopsy case of post-pandemic season A/H1N1pdm09 infection-associated acute respiratory distress syndrome (ARDS). The lung histology predominantly exhibited findings indicative of the exudative phase of diffuse alveolar damage, with similar inflammation severity observed in all sections. Furthermore, the lung sections only showed a few A/H1N1pdm09 antigen-positive cells along with a low viral RNA copy number. The sequence of th (mais)

Resumo: The 2016 seasonal influenza in Réunion in the southern hemisphere, was dominated by influenza A(H1N1)pdm09 (possibly genogroup 6B.1). An estimated 100,500 patients with acute respiratory infection (ARI) consulted a physician (cumulative attack rate 11.9%). Sixty-six laboratory-confirmed cases (65.7/100,000 ARI consultations) were hospitalised in an intensive care unit, the highest number since 2009. Impact on intensive care units was major. Correlation between severe cases was 0.83 between Réunion and France and good for 2009 to 2015.

Resumo: In October 2016, a severe infection with swine influenza A(H1N1) virus of the Eurasian avian lineage occurred in a child with a previous history of eczema in the Netherlands, following contact to pigs. The patient's condition deteriorated rapidly and required life support through extracorporeal membrane oxygenation. After start of oseltamivir treatment and removal of mucus plugs, the patient fully recovered. Monitoring of more than 80 close unprotected contacts revealed no secondary cases.

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27934828
Resumo: INTRODUCTION: Emerging virulent strains of influenza virus pose a serious public health threat with potential pandemic consequences. A novel avian influenza virus, H7N9, breached the species barrier from infected domestic poultry to humans in 2013 in China. Since then, it has caused numerous infections in humans with a close contact to poultry. MATERIALS AND METHODS: In this study, we describe the preliminary characterisation of five murine monoclonal antibodies (MAbs) developed against rec (mais)

Resumo: Real-world estimates of seasonal influenza vaccine effectiveness (VE) are important for early detection of vaccine failure. We developed a method for evaluating real-time in-season vaccine effectiveness (IVE) and overall seasonal VE. In a retrospective, register-based, cohort study including all two million individuals in Stockholm County, Sweden, during the influenza seasons from 2011/12 to 2014/15, vaccination status was obtained from Stockholm's vaccine register. Main outcomes were hospi (mais)
