Prognostic value of HPV circulating tumor DNA detection and quantification in locally advanced cervical cancer.

Background: Cervical cancers are mainly caused by an oncogenic HPV. For locally advanced stages, the standard treatment is radio-chemotherapy (RTCT) followed by brachytherapy. Nevertheless, the prognosis remains highly heterogeneous between patients.

Monitoring of Ultra-High Dose Rate Pulsed X-ray Facilities with Radioluminescent Nitrogen-Doped Optical Fiber.

We exploited the potential of radiation-induced emissions (RIEs) in the visible domain of a nitrogen-doped, silica-based, multimode optical fiber to monitor the very high dose rates associated with experiments at different pulsed X-ray facilities. We also tested this sensor at lower dose rates associated with steady-state X-ray irradiation machines (up to 100 keV photon energy, mean energy of 40 keV). For transient exposures, dedicated experimental campaigns were performed at ELSA (Electron et Laser, Source X et Applications) and ASTERIX facilities from CEA (Commissariat à l'Energie Atomique-France) to characterize the RIE of this fiber when exposed to X-ray pulses with durations of a few µs or ns.

Diagnostic and predictive accuracy of anti-mullerian hormone for ovarian function after chemotherapy in premenopausal women with early breast cancer.

Purpose: Accurate diagnosis and prediction of loss of ovarian function after chemotherapy for premenopausal women with early breast cancer (eBC) is important for future fertility and clinical decisions regarding the need for subsequent adjuvant ovarian suppression. We have investigated the value of anti-mullerian hormone (AMH) as serum biomarker for this.

Methods: AMH was measured in serial blood samples from 206 premenopausal women aged 40-45 years with eBC, before and at intervals after chemotherapy.

Novel Gd-doped silica-based optical fiber material for dosimetry in proton therapy.

Optical fibers hold promise for accurate dosimetry in small field proton therapy due to their superior spatial resolution and the lack of significant Cerenkov contamination in proton beams. One known drawback for most scintillation detectors is signal quenching in areas of high linear energy transfer, as is the case in the Bragg peak region of a proton beam. In this study, we investigated the potential of innovative optical fiber bulk materials using the sol-gel technique for dosimetry in proton therapy.

[Conflicting recommendations between the French national authority for health (HAS) and clinical practice guidelines (CNGOF); focus on 200 late medical abortions, conducted outside marketing authorizations].

Objectives: There are conflicting recommandations about late medical abortion: the French National College of Gynaecologists and Obstetricians (CNGOF) and the French Superior Health Authority are opposed. The aim was to assess misoprostol's efficiency in medical abortions at 9 to 14 weeks gestational age (GA) METHODS: This is an epidemiologic retrospective study led from March 2017 till January 2019, in Evreux's hospital, France, including all patients undergoing a medical abortion from 9 to 14 weeks GA. We followed the CNGOF's recommandations published in 2016.
