Within I-MOVE (European programme to monitor seasonal and pandemic influenza vaccine effectiveness (IVE)) five countries conducted IVE pilot case-control studies in 2008-9. One hundred and sixty sentinel general practitioners (GP) swabbed all elderly consulting for influenza-like illness (ILI). Influenza confirmed cases were compared to influenza negative controls. We conducted a pooled analysi...
BACKGROUND The ongoing 2016/17 influenza epidemic in France is characterized by the circulation of A(H3N2) viruses, known to cause more severe illness among at risk populations. OBJECTIVES The purpose of our study was to provide early influenza vaccine effectiveness (IVE) estimates for the ongoing influenza epidemic in France and compare these estimates over the six post-pandemic IVE. STUDY...
This paper describes an inductive learning method in probabilistic domain. It acquires an appropriate probabilistic model from a small amount of observation data. In order to derive an appropriate probabilistic model, a presumption tree with least description length is constructed. Description length of a presumption tree is defined as the sum of its code length and log-likelihood. Using a cons...
BACKGROUND The effectiveness of currently licensed vaccines against influenza has not been clearly established, especially among individuals at increased risk for complications from influenza. We used a test-negative approach to estimate influenza vaccine effectiveness (IVE) against hospitalization with laboratory-confirmed influenza based on data collected from the Global Influenza Hospital Su...
Background: This st udy aims t o evaluat e t he associat ion bet ween envi ronment al and socio-economic condit ions wit h asthma prevalence in t he eight ISAAC cent res in North-East Brazil. Met hods: Est imates on occurrence, severit y and medical diagnoses of asthma in the previous 12 months were compared using environmental and socioeconomic indicators. Associat ions were assessed using sim...
In a multicentre European hospital study we measured influenza vaccine effectiveness (IVE) against A(H3N2) in 2016/17. Adjusted IVE was 17% (95% confidence interval (CI): 1 to 31) overall; 25% (95% CI: 2 to 43) among 65-79-year-olds and 13% (95% CI: -15 to 30) among those ≥ 80 years. As the A(H3N2) vaccine component has not changed for 2017/18, physicians and public health experts should be awa...
BACKGROUND Most evidence of the effectiveness of influenza vaccines comes from studies conducted in primary care, but less is known about their effectiveness in preventing serious complications. Here, we examined the influenza vaccine effectiveness (IVE) against hospitalization with PCR-confirmed influenza in the predominant A(H3N2) 2011-2012 influenza season. METHODS A hospital-based, test-n...
Background: Most of cesarean deliveries are performed with regional anesthesia especially spinal anesthesia (SA). Disadvantages of SA include maternal hypotension and fetal asphyxia. This study was conducted to find prophylactic strategies for prevention of maternal hypotension in the women who were candidate for cesarean in Rasht Azzahra Hospital in 2001. Materials and Methods: This study was ...
We focus on some prelimi~lcny, theoretical and practical, requirements for an agent-based Jystem for cognitive interaction with older people. CVe stress (a) the acceptability of an artiJicia1 agent by elders; (h) a user model, which includes user knowledge, e-epectations, goals; (c) a representation system, (0 an interaction Jysfem, including physical and verbal interaction. We describe in some...
