TitleStructure of general-population antibody titer distributions to influenza A virus.
Published inSci Rep 2017, 7(1):6060
PubliekssamenvattingSeroepidemiological studies aim to understand population-level exposure and immunity to infectious diseases. Their results are normally presented as binary outcomes describing the presence or absence of pathogen-specific antibody, despite the fact that many assays measure continuous quantities. A population's natural distribution of antibody titers to an endemic infectious disease may include information on multiple serological states - naiveté, recent infection, non-recent infection, childhood infection - depending on the disease in question and the acquisition and waning patterns of immunity. In this study, we investigate 20,152 general-population serum samples from southern Vietnam collected between 2009 and 2013 from which we report antibody titers to the influenza virus HA1 protein using a continuous titer measurement from a protein microarray assay. We describe the distributions of antibody titers to subtypes 2009 H1N1 and H3N2. Using a model selection approach to fit mixture distributions, we show that 2009 H1N1 antibody titers fall into four titer subgroups and that H3N2 titers fall into three subgroups. For H1N1, our interpretation is that the two highest-titer subgroups correspond to recent and historical infection, which is consistent with 2009 pandemic attack rates. Similar interpretations are available for H3N2, but right-censoring of titers makes these interpretations difficult to validate.

The aim of the study was to compare success, mortality, and acquired rifampicin resistance in patients with INH-R pulmonary tuberculosis given different durations of rifampicin, ethambutol, and pyrazinamide (REZ); a fluoroquinolone plus 6 months or more of REZ; and streptomycin plus a core regimen of REZ.
Gemeten en berekende (NO2) concentraties in 2010 en 2011 : Een test van de standaardrekenmethoden 1 en 2Wesseling JP; van Velze K; Hoogerbrugge R; Nguyen L; Beijk R; Ferreira JA; ILG; M&V (Rijksinstituut voor Volksgezondheid en Milieu RIVM, 2013-04-26)Calculated nitrogen dioxide concentrations along roads closely resemble measured concentrations. Calculated and measured concentrations differ on average by less than one microgram per cubic meter of air. As a result, the methods used to calculate air quality comply with European criteria for air quality modeling. It should be noted that both calculated and measured concentrations are subject to uncertainties of several micrograms. Although air quality can be properly assessed through calculations and measurements, some uncertainty should therefore be taken into account when assessing air quality. These conclusions can be drawn from a study performed by the National Institute for Public Health and the Environment (RIVM), by request of the Ministry of Infrastructure and the Environment. This study also shows how the influence of trees on air quality in streets may be modeled more accurately, thereby improving the match between calculated and measured concentrations. For this purpose the RIVM proposes a refinement of the existing calculation method. For this research, more than 400 measurements of nitrogen dioxide concentrations in 2010 and 2011 have been compared to concentrations calculated using the Dutch Standard Calculation Methods for air quality. For Particulate Matter fewer measurements were available. The available data also complied with European quality criteria. Every year the RIVM assesses whether the results of the Standard Calculation Methods for air quality are in agreement with measurements by the Dutch National Air Quality Monitoring Network. Since the start of the National Collaboration Program on Air quality (NSL) much attention is drawn to the quality of the calculation methods as reliable models are needed to monitor the results of the NSL. For input for the calculations the NSL relies on the partners in the program. By request of the Ministry of Infrastructure and the Environment the research has been reviewed by the Wageningen University & Research centre (WUR) and the Flemish Institute for Technological Research (VITO). According to the reviews, the analyses in the report comply to a high scientific standard and the conclusions presented seem logical and correct.
