Twisk, Marianne van der Sande, Arne van Eeden, Danielle A. M. Heideman, Fiona R. M. van der Klis, Henry J C de Vries, Maarten F. Schim van der Loeff" "Background. We aimed to assess whether sexual exposure may explain all incident anal human papillomavirus (HPV) detections among men who have sex with men (MSM).Methods. A longitudinal study among MSM was conducted between 2010 and 2013 with visits every 6 months and up to 24 months of follow-up. Risk-factor questionnaires, blood samples, and anal and penile self-swabs were collected at each visit. Self-swabs were used for detection and genotyping of HPV by the broad spectrum L1 based SPF10 PCR DNA/enzyme immunoassay LiPA(25) system. Serum samples were tested for high-risk HPV (hrHPV) antibodies. Incident anal HPV detection rates among sexually non-, low, and highly exposed MSM were compared. Factors associated with incident anal hrHPV detection were assessed using multivariable Cox regression.Results. Seven hundred fourteen men (median age, 40 years; 39% human immunodeficiency virus [HIV] infected) were included in the analysis. Incident anal detections of all hrHPV types were observed among both sexually nonexposed and exposed MSM. In multivariable analyses, being highly sexually exposed, being HIV infected, and having a penile HPV infection were positively associated with incident anal HPV detection; those reporting more sex partners had a nonsignificantly increased risk of HPV detection.Conclusions. Incident anal hrHPV detection is common among recently nonexposed MSM, suggesting that a reactivated latent HPV infection instead of an incident infection may underlie incident HPV detection."

This procedure is very demanding computational-wise, which limits the research scope. This paper presents a highly efficient method for approximately quantifying congestion spillback due to incidents: Marginal Incident Computation (MIC). MIC superimposes the effect of an incident on a single base simulation run (without incidents) instead of carrying out a complete dynamic network loading with the incident, which would involve many calculations identical to the base simulation (e.g. prior to or far away from the incident). Whereas the results obtained with MIC vary only slightly from the outcome of a complete dynamic network loading, the gain in computation time is significant: a factor > 1100 for a case study of the Sioux Falls benchmark network." "Learning from Incidents and Incident Reporting: Safety Governance at a Belgian Nuclear Research Center" "Nicolas Rossignol, Michiel Van Oudheusden" "This article examines how incidents are governed in a Belgian Nuclear Research Center by way of an incident reporting system (IRS) named Retour d’Experiences (REX). Drawing on a documentary analysis of incident reports, interviews, and focus groups with personnel, it illustrates how REX enacts a safety governmentality centered on identifying incident causes and culprits. As this governmentality mode obscures the epistemic and politicalcharacter of incidents, it closes down important opportunities for collective learning about safety and safety governance. It is argued that joint reflectionabout incidents and resistances toward incident reporting serve as fruitful starting points for a more reflexive safety governance that makes explicit how decisions are made in high-risk contexts. Social scientists can enhancegovernance of this kind by pointing to different perceptions and evaluations of incidents and by insisting that contending interpretations are confronted and accounted for." "High HIV-1 incidence in young women masked by stable overall seroprevalence among childbearing women in Kinshasa, Zaire: estimating incidence from serial seroprevalence data" "V Batter, B Matela, M Nsuami, T Manzila, M Kamenga, F Behets, RW Ryder, WL Heyward, JM Karon, ME St.Louis" "OBJECTIVE: To describe the dynamics of the HIV-1 epidemic in childbearing women in Kinshasa, Zaire, by estimating incidence from serial seroprevalence studies. METHODS: In 1986 and 1989, 5937 and 4623 pregnant women, respectively, were screened for HIV-1 in Kinshasa. We estimated age-specific incidence from two seroprevalence surveys by using a birth-year cohort analysis and adjusting for differences in mortality and fertility between HIV-1-infected and uninfected women. Mortality and fertility data were measured in a cohort of women recruited from the survey in 1986 and followed until 1989. RESULTS: While the overall HIV-1 seroprevalence changed little (5.8% in 1986 and 6.5% in 1989; P = 0.17), the prevalence increased in birth-year cohorts of women under 25 years of age in 1989 from 3.2 to 6.2% (P < 0.001), but decreased for women above 25 years of age from 6.9 to 6.7% (P = 0.7). In addition, new HIV infections between 1986 and 1989 were balanced by a higher mortality and lower fertility observed in HIV-infected women. After adjusting for these effects, we estimated an overall 3-year cumulative HIV-1 incidence of 2.8 per 100 uninfected women [95% confidence interval (CI), 1.4-4.2]. The highest incidence, 5.7 per 100 (95% CI, 3.5-8.0), was in women aged 20-24 years in 1989. CONCLUSION: Despite an overall relatively stable HIV-1 prevalence in childbearing women in Kinshasa between 1986 and 1989, approximately 40% of all HIV-1 infections detected in the 1989 survey occurred between 1986 and 1989, and 60% occurred in women under 25 years of age in 1989" "The incidence and prevalence of upper tract urothelial carcinoma : a systematic review" "Ahmed Soualhi, Elke Rammant, Gincy George, Beth Russell, Deborah Enting, Rajesh Nair, Mieke Van Hemelrijck, Cecilia Bosco" "Lung cancer incidence differences in migrant men in Belgium, 2004-2013 : histology-specific analyses" "Katrien Vanthomme, Michael Rosskamp, Harlinde De Schutter, Hadewijch Vandenheede" "Background Immigrants make up an important share of European populations which has led to a growing interest in research on migrants' health. Many studies have assessed migrants' cancer mortality patterns, yet few have studied incidence differences. This paper will probe into histology-specific lung cancer incidence by migrant origin aiming to enhance the knowledge on lung cancer aetiology and different risk patterns among population groups. Methods We used data on all lung cancer diagnoses during 2004-2013 delivered by the Belgian Cancer Registry individually linked with the 2001 Belgian Census and the Crossroads Bank for Social Security. Absolute and relative inequalities in overall and histology-specific lung cancer incidence have been calculated for first-generation Italian, Turkish and Moroccan migrant men aged 50-74 years compared to native Belgian men. Results Moroccan men seemed to be the most advantaged group. Both in absolute and relative terms they consistently had lower overall and histology-specific lung cancer incidence rates compared with native Belgian men, albeit less clear for adenocarcinoma. Turkish men only showed lower overall lung cancer incidence when adjusting for education. On the contrary, Italian men had higher incidence for overall lung cancer and squamous cell carcinoma, which was explained by adjusting for education. Conclusions Smoking habits are likely to explain the results for Moroccan men who had lower incidence for smoking-related histologies. The full aetiology for adenocarcinoma is still unknown, yet the higher incidence among Italian men could point to differences in occupational exposures, e.g. to carcinogenic radon while working in the mines."
