The mechanisms of sudden-onset type adverse reactions to oseltamivir.

Autor(es): Hama, R; Bennett, C L
Fonte: Acta Neurol Scand;135(2): 148-160, 2017 Feb.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27364959
Resumo: Oseltamivir is contraindicated for people aged 10-19 in principle in Japan, due to concern about abnormal behaviours. Sudden death is another concern. This review examines growing evidence of their association and discusses underlying mechanisms of these sudden-onset type reactions to oseltamivir. First, the importance of animal models and the concept of human equivalent dose (HED) is summarized. Second, the specific condition for oseltamivir use, influenza infection, is reviewed. Third, fi (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: Recently, RNA viral infections caused by respiratory viruses, such as influenza, parainfluenza, respiratory syncytial virus, coronavirus, and Middle East respiratory syndrome-coronavirus (MERS-CoV), and Zika virus, are a major public health threats in the world. Although myriads of diagnostic methods based on RNA amplification have been developed in the last decades, they continue to lack speed, sensitivity, and specificity for clinical use. A rapid and accurate diagnostic method is needed (mais)

Resumo: AIM: To evaluate the performances of the Alere i influenza A&B test and to appraise its contribution to patient management. METHODS: In total, 267 samples were tested. Influenza A and B PCR was performed as the reference. For each positive result, the supervising physician was contacted to collect data regarding patient management. FINDINGS: The overall sensitivity and specificity of the Alere i were 91.4% and 97.6% for influenza A and 54.5% and 98.8% for influenza B, respectively. More spe (mais)

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). The influenz (mais)

Management of Infection for the Obstetrician/Gynecologist.

Autor(es): Eppes, Catherine
Fonte: Obstet Gynecol Clin North Am;43(4): 639-657, 2016 Dec.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27816152
Resumo: Pregnant women have an increased morbidity and mortality for certain illnesses owing to the physiologic and immunologic changes in pregnancy. Certain infections are common during pregnancy, including urinary tract infections and pneumonia. Others are uncommon, but yield increased severity, including influenza. Human immunodeficiency virus, although it does not increase in pathogenesis during pregnancy, requires specific attention and management in the context of pregnancy.

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)

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)
