Autor(es): Behzadi, Mohammad Amin; Ziyaeyan, Mazyar; Alborzi, Abdolvahab
Fonte: Arch Med Sci;12(6): 1286-1292, 2016 Dec 01.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27904520
Resumo: INTRODUCTION: Influenza A is known as a public health concern worldwide. In this study, a novel one-step real-time reverse transcription polymerase chain reaction (rtRT-PCR) assay was designed and optimized for the detection of influenza A viruses. MATERIAL AND METHODS: The primers and probe were designed based on the analysis of 90 matrix nucleotide sequence data of influenza type A subtypes from the GenBank database of the National Center for Biotechnology Information (NCBI).

Autor(es): Filleul, Laurent; Ranoaritiana, Dany Bakoly; Balleydier, Elsa; Vandroux, David; Ferlay, Clémence; Jaffar-Bandjee, Marie-Christine; Jaubert, Julien; Roquebert, Bénédicte; Lina, Bruno; Valette, Martine; Hubert, Bruno; Larrieu, Sophie; Brottet, Elise

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27918264
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: Nanoliter scale real-time PCR uses spatial multiplexing to allow multiple assays to be run in parallel on a single plate without the typical drawbacks of combining reactions together. We designed and evaluated a panel based on this principle to rapidly identify the presence of common disease agents in dogs and horses with acute respiratory illness. This manuscript describes a nanoscale diagnostic PCR workflow for sample preparation, amplification, and analysis of target pathogen sequences, (mais)

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27934581
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.

Seasonal Influenza A H1N1pdm09 Virus and Severe Outcomes: A Reason for Broader Vaccination in Non-Elderly, At-Risk People.

Autor(es): Minchole, Elisa; Figueredo, Ana L; Omeñaca, Manuel; Panadero, Carolina; Royo, Laura; Vengoechea, Jose J; Fandos, Sergio; de Pablo, Francisco; Bello, Salvador
Fonte: PLoS One;11(11): e0165711, 2016.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27832114
Resumo: BACKGROUND: Recent pandemics of influenza A H1N1pdm09 virus have caused severe illness, especially in young people. Very few studies on influenza A H1N1pdm09 in post-pandemic periods exist, and there is no information on the severity of both seasonal influenza A(H1N1) and A(H3N2) from the same season, adjusting for potential confounders, including vaccine. METHODS AND RESULTS: We performed a retrospective observational study of adults hospitalized during the 2014 season with influenza A(H1N (mais)

Forecasting Influenza Outbreaks in Boroughs and Neighborhoods of New York City.

Autor(es): Yang, Wan; Olson, Donald R; Shaman, Jeffrey
Fonte: PLoS Comput Biol;12(11): e1005201, 2016 Nov.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27855155
Resumo: The ideal spatial scale, or granularity, at which infectious disease incidence should be monitored and forecast has been little explored. By identifying the optimal granularity for a given disease and host population, and matching surveillance and prediction efforts to this scale, response to emergent and recurrent outbreaks can be improved. Here we explore how granularity and representation of spatial structure affect influenza forecast accuracy within New York City. We develop network mod (mais)

Detection of porcine reproductive and respiratory syndrome virus (PRRSV) and influenza A virus (IAV) in oral fluid of pigs.

Autor(es): Biernacka, Kinga; Karbowiak, Pawel; Wróbel, Pawel; Chareza, Tomasz; Czopowicz, Michal; Balka, Gyula; Goodell, Christa; Rauh, Rolf; Stadejek, Tomasz
Fonte: Res Vet Sci;109: 74-80, 2016 Dec.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27892877
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)

Influenza-Like Illness Diagnosis and Management in the Acute Care Setting.

Autor(es): Humiston, Sharon G; Pham, Thuylinh N
Fonte: Pediatr Emerg Care;32(12): 875-882, 2016 Dec.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27898629
Resumo: During influenza season, acute respiratory illness due to influenza is difficult to distinguish from other influenza-like illnesses, but testing should be reserved for situations when timely results will influence management or infection control measures. Immunization status and timing of disease onset notwithstanding, a neuraminidase inhibitor should be offered immediately for certain high-risk children; neuraminidase inhibitor treatment should be considered if shorter illness is warranted (mais)

Neues zur Influenza./ [Influenza: Whats new?]

Autor(es): Salzberger, Bernd; Schmidt, Barbara
Fonte: Dtsch Med Wochenschr;141(20): 1451-1454, 2016 Sep.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27701689
Resumo: The burden of disease of influenza in Germany has been dominated by high rates of complications in elderly patients in years with high circulation of H3N2 viruses after the introduction of the new H1N1 strain in 2009. Human infections with avian influenza viruses occur mostly in China. Due to the potential of reassortment with human strains these cases are monitored closely. The efficacy of neuraminidase inhibitors (NI) has been newly rated. In randomized studies effects on reduction of com (mais)

Fulminant myocarditis as a primary manifestation of H1N1 infection: A first reported case from Serbia.

Autor(es): Davidovic, Goran; Simovic, Stefan; Mitrovic, Slobodanka; Iric-Cupic, Violeta; Miloradovic, Vladimir
Fonte: Hellenic J Cardiol;57(3): 181-184, 2016 May - Jun.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27725100
Resumo: A 19-year-old male was admitted to our clinic with a diagnosis of suspected acute pericarditis and acute coronary syndrome. The initial diagnostics at our clinic revealed fulminant myocarditis. Twenty-four hours after admission, the patient's condition deteriorated, and he required mechanical ventilation and cardiopulmonary resuscitation. Unfortunately, the patient died. Clinical course, postmortem pathohistological findings and virus serology indicated that an H1N1 viral caused fulminant myocarditis and was the primary manifestation.
