Most odors of foods and drinks are mixtures of molecules. By means of the coupled Gas Chromatography-Olfactometry (GC-O) technique, single components of flavor mixtures can be separated, identified and verbally evaluated by subjects. The number of single molecules smelled by subjects during GC-O analysis (i.e., the number of odor-active compounds) was previously found to be linearly correlated with odor Threshold (T) score. Using the "Sniffin' Sticks" test, the same subjects were classified as normosmic or hyposmic. Hydrophobic odorants are captured and transported through the mucus layer by the odorant binding proteins (OBPs), particularly expressed in the olfactory cleft and associated with the olfactory function. In this study, subjects were genotyped for the rs2590498 (A/G) polymorphism of the OBPIIa gene, whose major allele A is associated with a higher olfactory sensitivity as compared to the minor allele G. One-way ANOVA showed a significant effect of the genotype of the OBPIIa locus on the a) T score; b) number of odor-active compounds smelled; c) intensity perceived when sniffing the complex odor of banana. In conclusion, the threshold olfactory performance, but also the individual ability to smell single molecules, can be attributed, partly at least, to the rs2590498 polymorphism of the OBPIIa gene.<br /><br /> The risk for surgical site infections (SSIs) is influenced by patient- and procedure-related factors. Urgent surgery represents a challenge in operative medicine and is frequently linked to a variety of complications, including SSIs.<br /><br /> We aimed to investigate whether urgency was significantly associated with SSI occurrence, and determine whether collection of this variable provided useful information for SSI surveillance.<br /><br /> We performed a retrospective data analysis of caesarean sections (C-sections) and colon surgeries conducted between 2017 and 2019 within the German national SSI surveillance network. A multivariable logistic regression model was utilized to determine the influence of urgency on SSI occurrence. For this purpose, data on procedures and SSIs were associated with available department- and patient-related parameters.<br /><br /> A total of 115,648 procedures were included in the analysis 78,288 C-sections and 37,360 colon surgeries. For C-sections, the SSI rate per 100 procedures was 0.98 (95% confidence interval 0.85-1.11) for urgent and 0.46 (0.40-0.53) for elective procedures (P&lt;0.001). For open colon surgeries, SSI rates were 9.66 (8.89-10.49) for urgent and 8.60 (8.13-9.11) for elective procedures (P&lt;0.001). For laparoscopic colon surgeries, SSI rates did not differ significantly. Multivariable analysis revealed that urgency significantly increased the likelihood of SSI occurrence only for C-sections.<br /><br /> Urgency significantly increased the SSI risk of C-sections, but not colon surgeries. Hence, collection of this variable is useful for SSI surveillance of C-sections, but may be dispensable for other procedures. Future analyses on the matter should therefore focus on other procedure types.<br /><br />Urgency significantly increased the SSI risk of C-sections, but not colon surgeries.

Data on nosocomial influenza infection are limited.<br /><br /> To describe nosocomial cases of seasonal influenza in south-western Switzerland.<br /><br /> This study was conducted during two seasonal influenza epidemics from 2016 to 2018 in 27 acute care public hospitals in south-western Switzerland. During these two time-periods, every patient hospitalized for &gt;72 h who was positively screened by reverse transcription-polymerase chain reaction or antigen detection for influenza was included in the survey. Characteristics of patients included age, sex, and comorbidities. Included patients were followed up until discharge or death. Complications and administration of antineuraminidases and/or antibiotics were registered.<br /><br /> The median influenza vaccine coverage of healthcare workers was 40%. In all, 836 patients were included (98% with type A influenza virus in 2016-2017; 77% with type B virus in 2017-2018). Most patients (81%) hdequate additional measures to prevent dissemination, including the timely administration of antineuraminidases to avoid antibiotic use (and misuse).<br /><br /> Healthcare workers (HCWs) have been disproportionately affected by coronavirus disease 2019 (COVID-19), which may be driven, in part, by nosocomial exposure. If HCW exposure is predominantly nosocomial, HCWs in paediatric facilities, where few patients are admitted with COVID-19, may lack antibodies to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and be at increased risk during the current resurgence.<br /><br /> To compare the seroprevalence of SARS-CoV-2 amongst HCWs in paediatric facilities in seven European countries and South Africa (N=8).<br /><br /> All categories of paediatric HCWs were invited to participate in the study, irrespective of previous symptoms. A single blood sample was taken and data about previous symptoms were documented. [https://www.selleckchem.com/products/gsk650394.html find more] Serum was shipped to a central laboratory in London where SARS-CoV-2 immunoglobulin G was measured.<br /><br /> In total, 4114 HCWs were recruited between 1<br /><br /> May and mid-July 2020. The range of seroprevalence was 0-16.93%. The highest seroprevalence was found in London (16.93%),burden countries have very low seroprevalence rates and thus are likely to be susceptible to COVID-19. Their susceptibility to infection may affect their ability to provide care in the face of increasing cases of COVID-19, and this highlights the need for appropriate preventative strategies in paediatric healthcare settings.<br /><br /> The fasting, 1-h, and 2-h plasma glucose (PG) levels during oral glucose tolerance test represent different glucose metabolic functions. We examined whether averaging these PG indices (GLU<br /><br /> ) results in a better predictor of future type 2 diabetes (T2DM).<br /><br /> 7533 participants were followed up biannually for 12years. Hazard ratios (HRs), area under the curve (AUC) of the receiver-operating characteristic, and the net reclassification index (NRI) for T2DM were calculated to compare the discriminative ability of GLU<br /><br /> versus other PG indices.<br /><br /> The adjusted HRs and 95% confidence intervals for an increase in SD of GLU<br /><br /> was 2.50 (2.36-2.65) and 1.88 (1.73-2.04) in T2DM-free and normal glucose tolerance (NGT) participants, respectively. The AUC of GLU<br /><br /> was higher than that of fasting PG, 1-h, and 2-h PG values for T2DM-free (0.79 versus 0.67, 0.77, and 0.73) and NGT (0.73 versus 0.65, 0.72, and 0.61). The model using GLU<br /><br /> improved the classification of the models with fasting PG, 1-h, and 2-h PG values (NRI 0.
