Introduction: The flu, a condition that can affect the elderly by increasing the risk of serious complications can be prevented through vaccination. Estimate the prevalence of signs and symptoms suggestive of influenza in a group of elderly either vaccinated or unvaccinated against influenza was the objective this study. Methods: This is a cross-sectional study performed in a Brazilian City. A structured questionnaire was employed to identify the presence of signs and symptoms of influenza in individuals aged 60 years or over. For analysis of associations between variables the prevalence ratio (PR) and its 95% confidence interval (95% CI) were used. Results: One hundred ninety-six participants were interviewed, of whom 57.7% were female. The average age was 69.7 years. About 25% of the vaccinated and 20% of the unvaccinated in 2009, and 25% of the vaccinated and 22.5% of the unvaccinated in 2010 reported having the flu. Among the vaccinated and unvaccinated in 2009 and 2010, there was no verified association between vaccination and influenza (PR=1.24; [95% CI: 0.63-2.43] and PR=1.11; [95% CI: 0.59-2.09], respectively). Conclusions: This study suggests that, among the elderly selected, the vaccination coverage for influenza is below the ideal...

Há muitos estudos sobre plantas medicinais brasileiras, porém a carência de pesquisas relacionadas à segurança alimentar de plantas brasileiras usadas como alimento ainda é consideravelmente grande. A maioria dos alcaloides são substâncias tóxicas que podem ser encontrados em uma grande variedade de plantas medicinais e alimentícias, inclusive em espécies de Passiflora chamadas popularmente no Brasil de "maracujá". As pesquisas sobre as diversas espécies de Passiflora, em grande parte estão relacionadas com as folhas e frutos e na maioria das vezes as sementes são consideradas como resíduo. As metodologias analíticas modernas para análises na área de alimentos, utilizando SBSE com fase extratora de PDMS, tem o objetivo de facilitar o preparo de amostras complexas e diminuir os resíduos orgânicos gerados na etapa de preparo da amostra. Para isso, este estudo teve como objetivo a análise de alcaloides harmânicos pelo método SBSE/CLAE-Flu dual, adaptado para a quantificação de harmana e de harmina em sementes de maracujá azedo. O método foi especifico e linear para os alcaloides estudados (r2 = 0,996 para harmana e r2 = 0,999 para harmina). Os ensaios de repetibilidade e de precisão intermediária confirmam a precisão do método. Os testes de recuperação (entre 92...

O maracujá, nome popular atribuído ao fruto das diversas espécies do gênero Passiflora, da família Passifloraceae, é amplamente comercializado e consumido no mundo, sendo o Brasil um dos maiores produtores do fruto. Alguns estudos apontam possível toxicidade relacionada às espécies de Passiflora, principalmente P. incarnata. No entanto, há pouco conhecimento acerca das espécies P. edulis e P. alata, sobretudo em relação à polpa e sementes. Os extratos da polpa e das sementes dos frutos dessas duas espécies de "maracujá", Passiflora alata e Passiflora edulis, foram estudados com o objetivo de identificar alcaloides harmânicos, pelo preparo das amostras por extração por sorção em barra magnética recoberta com polidimetilsiloxano (SBSE-PDMS) e SBSE recoberta com polietilenoglicol silicone (SBSE-EG Silicone) e análise por cromatografia líquida de alta eficiência com detector por fluorescência (CLAE-Flu) e cromatografia líquida de ultra eficiência acoplada à espectrometria de massas sequencial (CLUE-EM/EM). A análise dos alcaloides harmana e harmina nos extratos da polpa de P. alata foi feita por meio do método de adição de padrão e mostrou menor quantidade destes alcaloides, em comparação com os resultados da análise dos extratos da polpa dos frutos de P. edulis...

A method for the quantification of the alkaloids harmane and harmine in sour passion fruit (Passiflora edulis f. flavicarpa O. Degener, Passifloraceae) pulp and seeds by stir-bar sorptive extraction and high performance liquid chromatography with fluorescence detection (dual SBSE-LC/Flu) is described. The SBSE parameters were optimized using a fractional factorial design, and the dual SBSE-LC/Flu method was validated following the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) guidelines. The high sensitivity and minimal sample handling of the dual SBSE-LC/Flu method make it attractive for application in phytochemical analysis or in the food industry.

Directigen FLU-A, a new enzyme immunoassay membrane test, rapidly detects influenza A virus antigen in specimens from patients. Nasopharyngeal washes and pharyngeal gargles were used to determine the effectiveness of the assay as applied to different types of routinely collected clinical samples. All specimens had been previously shown to contain influenza A virus by virus isolation in tissue culture. Directigen FLU-A was 90% sensitive (95% confidence interval, 56 to 99.7%) with nasopharyngeal washes but only 39% sensitive (95% confidence interval, 17 to 64%) with pharyngeal gargles (P = 0.018) when used with samples containing similar amounts of infectious virus (50% tissue culture infective dose, 1.0 to 4.5). The intensity of the positive reaction with Directigen FLU-A did not correlate with the amount of virus in the specimens. Directigen FLU-A was found to detect cell-associated antigen more readily than free virus; only 20 infected cells were required to identify cell-associated influenza A virus antigen, whereas the limit of detection for free virus was 1.63 x 10(3) infectious virus particles. These findings suggest that Directigen FLU-A detects the cell-associated antigen present in clinical specimens rather than free virus. In addition...

Directigen FLU-A, an enzyme immunoassay membrane test, was compared prospectively to isolation in cell culture and direct immunofluorescence (IF) for the detection of influenza A virus. One hundred ninety specimens were evaluated by Directigen FLU-A and cell culture; 184 of these specimens were also tested by direct IF. The sensitivity of Directigen FLU-A compared to isolation in cell culture and direct IF was 100%. The specificities of Directigen FLU-A compared to isolation and direct IF were identical, 91.6%. Fourteen specimens that were positive by Directigen FLU-A did not yield virus in culture; two of the specimens, however, were positive by direct IF, and four other specimens were not specimens of choice for the test. A positive Directigen result had positive predictive values of 62.6 and 75.0% compared to isolation and direct IF, respectively; a positive Directigen result with an intensity reading of 2+ or greater, however, had positive predictive values of 85 and 100% compared to isolation and direct IF, respectively. In all comparisons, the negative predictive value was 100%. There was no evidence that cross-reactivity occurred with non-influenza A antigens. Directigen FLU-A should serve as a convenient screening test for influenza A and as a rapid test supported by isolation in cell culture during an influenza outbreak.

flu, a gene of Escherichia coli K-12, was discovered and mapped between his and shiA. It is shown that flu is a metastable gene that changes frequently between the flu+ and flu states. flu+ variants give stable homogeneous suspensions, are piliated, and form glossy colonies. flu variants aggregate, fluff and sediment from suspensions, are nonpiliated, and form frizzy colonies. flu+ and flu variants can be isolated from most strains. Implications of these observations are discussed, and it is demonstrated that flu+ variants of strain P678-54 yield three times more minicells than flu variants.

The Xpert Flu Assay cartridge is a next-generation nucleic acid amplification system that provides multiplexed PCR detection of the influenza A, influenza A 2009 H1N1, and influenza B viruses in approximately 70 min with minimal hands-on time. Six laboratories participated in a clinical trial comparing the results of the new Cepheid Xpert Flu Assay to those of culture or real-time PCR with archived and prospectively collected nasal aspirate-wash (NA-W) specimens and nasopharyngeal (NP) swabs from children and adults. Discrepant results were resolved by DNA sequence analysis. After discrepant-result analysis, the sensitivities of the Xpert Flu Assay for prospective NA-W specimens containing the influenza A, influenza A 2009 H1N1, and influenza B viruses compared to those of culture were 90.0%, 100%, and 100%, respectively, while the sensitivities of the assay for prospective NP swabs compared to those of culture were 100%, 100%, and 100%, respectively. The sensitivities of the Xpert Flu Assay for archived NA-W specimens compared to those of Gen-Probe ProFlu+ PCR for the influenza A, influenza A 2009 H1N1, and influenza B viruses were 99.4%, 98.4%, and 100%, respectively, while the sensitivities of the Xpert Flu Assay for archived NP swabs compared to those of ProFlu+ were 98.1%...

Respiratory tract infections caused by influenza A and B viruses often present nonspecifically, and a rapid, high-throughput laboratory technique that can identify influenza viruses is clinically and epidemiologically desirable. The PLEX-ID Flu assay (Abbott Molecular Inc., Des Plaines, IL) incorporates multilocus PCR and electrospray ionization-mass spectrometry to detect and differentiate influenza A 2009 H1N1 (H1N1-p), seasonal H1N1 (H1N1-s), influenza A H3N2, and influenza B viruses in nasopharyngeal swab (NPS) specimens. The clinical performance characteristics of the PLEX-ID Flu assay in symptomatic patients were determined in this multicenter trial. A total of 2,617 prospectively and retrospectively collected NPS specimens from patients with influenza-like illness between February 2008 and 28 May 2010 were eligible for inclusion in the study. Each specimen was tested in parallel by the PLEX-ID Flu assay and by the Prodesse ProFLU+ assay (Prodesse Inc., Madison, WI), to detect influenza A and B viruses. Specimens testing positive for influenza A virus by ProFLU+ were subtyped as H1N1-p, H1N1-s, or H3N2 by using the ProFAST+ assay (Gen-Probe Prodesse Inc.). The reproducibility of the PLEX-ID Flu assay ranged from 98.3 to 100.0%...

We postulated that fludarabine (Flu) instead of cyclophosphamide (Cy) combined with IV busulfan (Bu) as preconditioning for allogeneic hematopoietic stem cell transplantation (HSCT) would improve safety and retain antileukemic efficacy. 67 patients received BuCy2 and subsequently 148 patients received Bu-Flu. We used a Bayesian method to compare outcomes between these non-randomized patients. The groups had comparable pretreatment characteristics, except that Bu-Flu patients were older (46 vs. 39 years, p< 0.01), more often had unrelated donors (47.3% vs. 20.9%, p< 0.0003), and had shorter median follow-up (39.7 vs. 74.6 months). To account for improved supportive care and other unidentified factors that may affect outcome (“period” effects), 78 AML patients receiving Melphalan-Flu (“MF”), treated in parallel during this time (1997 to 2004) were used to estimate the period effect; The MF patients’ outcomes worsened during this period. Therefore, the period effect is unlikely to explain the greatly improved outcome with Bu-Flu. Patients transplanted with Bu-Flu in CR1 had a 3-year overall survival and event-free-survival (EFS) of 78% and 74%, respectively, while CR1 patients younger than age 41 had a 3-year EFS of 89%. These results support replacing BuCy±ATG with Bu-Flu±rabbit-ATG...

This article examines flu vaccination beliefs and practices produced during a survey of undergraduate students in Spring 2012 (IRB#10-732). This research uses the methods of rhetorical analysis — or the study of persuasive features and arguments used in language — to examine statements respondents made regarding flu and flu vaccine. In these responses, students generated unique categories of arguments about the perceived dangers of flu vaccination, including the assertion that vaccines cause disease (including illnesses and conditions other than flu), that vaccines are toxic medicines, and that vaccines carry unknown, population-wide risks that are inadequately acknowledged. This study provides insight into vaccination beliefs and rationales among a population at risk of flu (college students) and suggests that further study of this population may yield important keys to addressing flu vaccine concerns as expressed by college students. Rhetorical analysis also offers a useful set of methods to understanding vaccination beliefs and practices, adding to existing methods of study and analysis of vaccination practices and beliefs in medicine and public health.

Many national organizations call for medical students to receive more public health education in medical school. Nonetheless, limited evidence exists about successful servicelearning programs that administer preventive health services in nonclinical settings. The Flu Crew program, started in 2001 at the Stanford University School of Medicine, provides preclinical medical students with opportunities to administer influenza immunizations in the local community. Medical students consider Flu Crew to be an important part of their medical education that cannot be learned in the classroom. Through delivering vaccines to where people live, eat, work, and pray, Flu Crew teaches medical students about patient care, preventive medicine, and population health needs. Additionally, Flu Crew allows students to work with several partners in the community in order to understand how various stakeholders improve the delivery of population health services. Flu Crew teaches students how to address common vaccination myths and provides insights into implementing public health interventions. This article describes the Stanford Flu Crew curriculum, outlines the planning needed to organize immunization events, shares findings from medical students’ attitudes about population health...

This report reviews some of the accomplishments of the Global Program for Avian Influenza Control and Human Pandemic Preparedness and Response (GPAI). This multisectoral program comprised 72 projects in 60 developing countries in all regions and received $1.3 billion in financing from the World Bank. This support for GPAI projects was one of the World Bank s contributions to a coordinated global response to the threats of avian and pandemic influenzas, which benefited from financing of $4 billion from 35 donors in 2006-2013. Thanks to this support, developing countries strengthened their capacity for early and effective disease control, bringing substantial public health and economic benefits to the countries and to the world. According to Harvard University Professor and former US Treasury Secretary Lawrence Summers, "[veterinary and human public health systems are] probably the single most important area for productive investment on behalf of mankind." Indeed, circulation of the highly pathogenic avian flu virus was reduced...

In response to its poor performance during the 2012-2013 flu season, Google Flu Trends (GFT) engineers announced a redesign of the GFT algorithm. Two changes were made: (1) dampening anomalous media spikes and (2) using ElasticNet, rather than regression, for estimation. This paper identifies several problems that persist in the new algorithm. First, the transparency problems identified in our earlier Science paper appear to have, if anything, become worse. Second, there are reasons to doubt whether a spike in media attention was the only, or primary, cause of GFT's errors. Finally, there is strong evidence that GFT is still not using all the information at its disposal to make accurate measurements of flu prevalence. While it is too early to give a complete evaluation of the new algorithm, these results are discouraging.; Other Research Unit

Based on Bourdieu’s theory of social capital, this article analyses Swedes’ willingness to vaccinate during the swine flu outbreak in autumn 2009. The analysis is based partly on responses to a survey of 3,000 Swedes that was conducted when the virus was spreading, and partly on a comprehensive content analysis of the largest Swedish news media’s coverage of swine flu. The starting point is a model where people’s vaccination willingness is analysed against the background of their social capital, media consumption, perceived concern about catching the virus, and trust in how the authorities were handling the influenza virus. The results show that social capital in terms of class affiliation, education and profession in covariance with media consumption impacted both the perception of concern and trust in the authorities, and that, in this case, trust in the authorities had greater significance for the rate of vaccination than the perception of concern.

We analyzed the 124 deaths reported in Portugal form flu pandemic. The estimated mortality rate was 1.17/100 000 population. 60% were males, the average age was 47.6 and 66.1% had at least one risk factor. Chronic lung and heart diseases were the most common risk factors. Viral pneumonia was the major cause of death. 11% of the deceased had no treatment with neuraminidase inhibitors and none was vaccinated against the pandemic strain of flu. Compared to average life expectancy, we estimated that 3859 years of potential life were lost. In the future, we should work on improved strategies for risk communication for health professionals and general public.
