Ultra-deep sequencing provides insights into the virology of hepatitis C super-infections in a case of three sequential infections with different genotypes

The current epidemic of Hepatitis C infection in HIV-positive men who have sex with men is associated with increasing use of recreational drugs. Multiple HCV infections have been reported in haemophiliacs and intravenous drug users. Using ultra-deep sequencing analysis, we present the case of an HIV-positive MSM with evidence of three sequential HCV infections, each occurring during the acute phase of the preceding infection, following risk exposures. We observed rapid replacement of the original strain by the incoming genotype at subsequent time points. The impact of HCV super-infection remains unclear and UDS may provide new insights.

A Single-Frame Super-Resolution Innovative Approach

Super-resolution refers to the process of obtaining a high resolution image from one or more low resolution images. In this work, we present a novel method for the super-resolution problem for the limited case, where only one image of low resolution is given as an input. The proposed method is based on statistical learning for inferring the high frequencies regions which helps to distinguish a high resolution image from a low resolution one. These inferences are obtained from the correlation between regions of low and high resolution that come exclusively from the image to be super-resolved, in term of small neighborhoods. The Markov random fields are used as a model to capture the local statistics of high and low resolution data when they are analyzed at different scales and resolutions. Experimental results show the viability of the method.

Chimiothérapie intra-artérielle super-sélective dans l'artère ophtalmique en cas de rétinoblastome avancé chez l'enfant.

Objectifs: Etude prospective sur l'efficacité de la chimio-perfusion super-sélective avec Melphalan dans l'artère ophtalmique en tant qu'agent tumoricide chez l'enfantatteint de rétinoblastome avancé, pour éviter l'énucléation chirurgicale et/ou la radiothérapie externe. Matériels et méthodes: 19 enfants (âge moyen 25 mois) atteints de rétinoblastome de groupe D ont reçu 1 à 3 séances d'administration intra-artérielle de Melphalan (0,35 mg/kg) dans l'artère ophtalmique sous anesthésie générale. Au total 48 procédures ont été réalisées. Chaque séance était associée à une injection intra-vitréenne deMelphalan, ainsi qu'à une thermothérapie et/ou une cryothérapie. Résultats: Le traitement a été effectué avec succès chez 17/19 enfants avec une régression importante du volume tumoral. L'énucléation ainsi que la radiothérapie externeont pu être évitées dans 15/17 enfants, sur un suivi moyen d'une année. Aucune complication systémique ou thromboembolique n'a été observée. Lescomplications locales ont comporté 2 décollements de la rétine, 5 oedèmes conjonctivaux et palpébraux, 1 cas de pigmentation cutanée locale, 1 vasospasmetransitoire de l'artère carotide interne et 2 cas d'artériopathie occlusive choroïdienne sectorielle . Conclusion: L'administration intra-artérielle de Melphalan s'avère être très efficace dans les cas avancés de rétinoblastome chez l'enfant, aussi bien comme techniquecurative que pour éviter l'énucléation et/ou la radiothérapie externe.

Mortality among 24,865 workers exposed to polychlorinated biphenyls (PCBs) in three electrical capacitor manufacturing plants: a ten-year update.

The objective of this analysis was to evaluate mortality among a cohort of 24,865 capacitor-manufacturing workers exposed to polychlorinated biphenyls (PCBs) at plants in Indiana, Massachusetts, and New York and followed for mortality through 2008. Cumulative PCB exposure was estimated using plant-specific job-exposure matrices. External comparisons to US and state-specific populations used standardized mortality ratios, adjusted for gender, race, age and calendar year. Among long-term workers employed 3 months or longer, within-cohort comparisons used standardized rate ratios and multivariable Poisson regression modeling. Through 2008, more than one million person-years at risk and 8749 deaths were accrued. Among long-term employees, all-cause and all-cancer mortality were not elevated; of the a priori outcomes assessed only melanoma mortality was elevated. Mortality was elevated for some outcomes of a priori interest among subgroups of long-term workers: all cancer, intestinal cancer and amyotrophic lateral sclerosis (women); melanoma (men); melanoma and brain and nervous system cancer (Indiana plant); and melanoma and multiple myeloma (New York plant). Standardized rates of stomach and uterine cancer and multiple myeloma mortality increased with estimated cumulative PCB exposure. Poisson regression modeling showed significant associations with estimated cumulative PCB exposure for prostate and stomach cancer mortality. For other outcomes of a priori interest--rectal, liver, ovarian, breast, and thyroid cancer, non-Hodgkin lymphoma, Alzheimer disease, and Parkinson disease--neither elevated mortality nor positive associations with PCB exposure were observed. Associations between estimated cumulative PCB exposure and stomach, uterine, and prostate cancer and myeloma mortality confirmed our previous positive findings.
