Resumo: Background: : Pandemic influenza has potential to overwhelm healthcare resources. There is uncertainty over performance of existing triage tools for hospital admission and discharge decisions. Aim: : Our aim was to identify clinical criteria that predict safe discharge from hospital and develop a pragmatic triage tool to guide physician decision-making. Design: : We retrospectively examined an existing database of patients who presented to the Royal Liverpool University Hospital during the (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)

METHODS: Patients hospitalized with ILI were included in this prospective, multicentre study carried out in six French hospitals during three consecutive influenza seasons (2012-2015). RSV and other respiratory viruses were detected by multiplex PCR in nasopharyngeal swabs. Risk factors for RSV infection were id (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)

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: 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).

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.

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.

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)
