Autor(es): Mc Mahon, Aisling; Martin-Loeches, Ignacio
Fonte: Expert Rev Clin Pharmacol;10(1): 81-95, 2017 Jan.
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)

Generation and characterisation of monoclonal antibodies specific to avian influenza H7N9 haemagglutinin protein.

Autor(es): Malik, A; Mallajosyula, Vva; Mishra, N N; Arukha, A P; Varadarajan, R; Gupta, S K
Fonte: Indian J Med Microbiol;34(4): 489-494, 2016 Oct-Dec.
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)

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27936139
Resumo: BACKGROUND: Chongqing is the largest municipality and located in Southwestern of China, with over 30 million registered inhabitants. There are few reports regarding the epidemiology of influenza in Chongqing. The objective of the paper is to explore the epidemiology of influenza in Chongqing, in order to provide scientific basis for prevention and control of influenza. METHODOLOGY /PRINCIPAL FINDINGS: From 2011 to 2015, we collected information on influenza-like illness (ILI) patients fulfi (mais)

Real-time real-world analysis of seasonal influenza vaccine effectiveness: method development and assessment of a population-based cohort in Stockholm County, Sweden, seasons 2011/12 to 2014/15.

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27813473
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)

Resumo: Recently oral fluid has become a novel sample type for pathogen nucleic acid and antibody detection, as it is easy to obtain with non-invasive procedures. The objective of the study was to analyze porcine reproductive and respiratory syndrome virus (PRRSV) and influenza A virus (IAV) circulation in growing pigs from three Polish production farms, using Real Time PCR and ELISA testing of oral fluid and serum. Oral fluids were collected every 2weeks, in the same 3-4 pens of pigs aged between (mais)

Fonte: Int J Infect Dis;52: 55-58, 2016 Nov.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27720945
Resumo: As the characteristics and accuracy of rapid influenza detection tests (RIDTs) vary, the development of a high-performance RIDT has been eagerly anticipated. In this study, the new RIDT GOLD SIGN FLU and the existing RIDT Quick Navi-Flu were evaluated in terms of detecting the antigens of influenza viruses A and B in Japanese adults with influenza-like symptoms. The study was performed from December 2013 to March 2014. Among the 123 patients from whom nasopharyngeal swab specimens were coll (mais)

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27724934
Resumo: BACKGROUND: Influenza A viruses of swine (IAV-S) cause acute and subclinical respiratory disease. To increase our understanding of the etiology of the subclinical form and thus help prevent the persistence of IAV-S in pig populations, we conducted active virologic surveillance in Vietnam, the second-largest pig-producing country in Asia, from February 2010 to December 2013. RESULTS: From a total of 7034 nasal swabs collected from clinically healthy pigs at 250 farms and 10 slaughterhouses, (mais)

Resumo: Influenza antigenic and genetic characterisation data are crucial for influenza vaccine composition decision making. Previously, aggregate data were reported to the European Centre for Disease Prevention and Control by European Union/European Economic Area (EU/EEA) countries. A system for collecting case-specific influenza antigenic and genetic characterisation data was established for the 2013/14 influenza season. In a pilot study, 11 EU/EEA countries reported through the new mechanism. We (mais)
