Abstract
PURPOSE to assess overranging (OR) as a function of pitch, collimation and rotation time for three commonly used CT models in France. METHODS OR was measured using XR-SP2 Gafchromic films (Ashland, USA) and computed from exposure data for three widely used CT models in France. The impact of collimation, pitch and rotation time on OR was analyzed while comparing the three CT models. RESULTS for a typical head protocol, measured OR was found to be equal to 1.64 cm for CT scan A, 0.5 cm for CT scan B and 3.44 cm for CT scan C. OR values were respectively of 4.47, 3.24 and 7.81 cm for the typical chest protocol and the 3 CT models. OR was lowest at pitch values <1 for CT scan A, while it linearly increased with pitch for CT scan B and was lowest for high pitch values for CT scan C. Additionally, OR increase with collimation (24 mm to 38.4 mm) was most pronounced for CT scan B (factor of 2.2 for low pitch (0.5) and 2.8 for high pitch (1.2)) while it increased linearly regardless of the pitch for CT scans A and C. Rotation time also proved to slightly affect OR mainly for CT scan B (up to 2.2 mm). CONCLUSION the present study shows that overranging remains an issue in modern CT scanners with large disparities across the vendors.

Abstract
Lymphedema (LD) refers to a condition of lymphatic dysfunction associated with excessive fluid accumulation, fibroadipose tissue deposition and swelling. In industrialized countries, LD development mainly results from a local disruption of the lymphatic network by an infection or cancer-related surgery (secondary LD). In the absence of efficient therapy, animal models are needed to decipher the cellular and molecular mechanisms underlying LD and test putative drugs. In this study, we optimized and characterized a murine model of LD that combines an irradiation of the mice hind limb and a radical surgery (lymph node resection associated to lymphatic vessel ligation). We investigated the respective roles of irradiation and surgery in LD formation by comparing their impacts, alone or in combination (with different intervention sequences), on eight different features of the pathology: swelling (paw thickness), indocyanine green (ICG) clearance, lymphatic vasculature remodeling, epidermal and dermal thickening, adipocyte accumulation, inflammatory cell infiltration and collagen deposition. This study supports the importance of radiation prior to surgery to experimentally induce a rapid, severe and sustained tissue remodeling harboring the different hallmarks of LD. We provide the first experimental evidence for an excessive deposition of periostin (POSTN) and tenascin-C (TNC) in LD. Through a computerized method of digital image quantification, we established the spatial map of lymphatic expansion, as well as collagen, POSTN and TNC deposition in papillary and reticular dermis of lymphedematous skins. This mouse model is available to study the patho-physiology of LD and test potential therapeutic targets.

Abstract
BACKGROUND Mechanisms that preclude lung metastasis are still barely understood. The possible consequences of allergic airways inflammation on cancer dissemination were studied in a mouse model of breast cancer. METHODS Balb/c mice were immunized and daily exposed to ovalbumin (OVA) from day 21. They were subcutaneously injected with 4T1 mammary tumor cells on day 45 and sacrificed on day 67. Lung metastases were measured by biophotonic imaging (IVIS® 200 Imaging System) and histological measurement of tumor area (Cytomine software). Effects of CCL11 were assessed in vivo by intratracheal instillations of recCCL11 and in vitro using Boyden chambers. CCR3 expression on cell surface was assessed by flow cytometry. RESULTS The extent of tumor metastases was significantly higher in lungs of OVA-exposed mice and increased levels of CCL11 expression were measured after OVA exposure. Migration of 4T1 cells and neutrophils was stimulated in vitro and in vivo by recCCL11. 4T1 cells and neutrophils express CCR3 as shown by flow cytometry and a selective CCR3 antagonist (SB-297006) inhibited the induction of 4T1 cells migration and proliferation in response to recCCL11. CONCLUSIONS Allergic inflammation generated by exposure to allergens triggers the implantation of metastatic cells from primary breast tumor into lung tissues plausibly in a CCL11-CCR3-dependent manner. This indicates that asthma related inflammation in lungs might be a risk factor for lung metastasis in breast cancer patients.

Abstract
Spinal anaesthesia for elective caesarean section is associated with maternal hypotension, secondary to alteration of sympathetic tone and hypovolemia, in up to 70% of cases. Measurement of the subaortic variation in the velocity time integral (VTI) after passive leg raising allows prediction of fluid responsiveness. Our objective, in this prospective single-centre observational study, was to assess the ability of change in VTI after 45° passive leg raising to predict hypotension after spinal anaesthesia. Ultrasound measurements were performed just before elective caesarean section. Anaesthesia, intravenous coloading and prophylactic vasopressor treatment were standardised according to current guidelines. We studied 40 women. Hypotension occurred in 17 (45%) women. The area (95%CI) under the receiver operating characteristics (ROC) curve for the prediction of spinal hypotension was 0.8 (0.6-0.9; p = 0.0001). Seventeen women had a change in VTI with leg elevation ≤ 8%, which was predictive for not developing hypotension, and 11 had a change ≥ 21%, predictive for hypotension. The grey zone between 8% and 21%, with inconclusive values, included 12 women. We suggest that cardiac ultrasound provides characterisation of the risk of hypotension following spinal anaesthesia at elective caesarean section, and therefore may allow individualised strategies for prevention and management.

Abstract
Abstract
BACKGROUND: Research suggests an association between certain psychiatric conditions and high-risk adolescent sexual activity. In fact, pregnancy is three times more likely in adolescent girls with major mental health disorders in comparison to those without mental illness. Given a proportion of adolescents with mental health disorders will require admission to the hospital for acute psychiatric concerns, this could serve as a useful time point to screen for risky sexual behaviour in high-risk youth.
OBJECTIVES: Our objective was to review the history screening practices at admission and throughout an inpatient stay for adolescents on an inpatient psychiatry unit and to review any resulting referrals or treatment relating to sexual health.
DESIGN/METHODS: A chart review was conducted which included one hundred randomly selected adolescent patients admitted to an inpa-tient psychiatry unit over a 12 month period (January 2013-December 2013). Measures extracted from charts included demographic information, reason for admission, psychiatric diagnoses, documented sexual health related data and any investigations, co-morbidities, treatment and/or follow up booked related to sexual health. Ethics approval was obtained prior to study onset.
RESULTS: The majority of patients were female (79%) and the mean age of study subjects was 15.24 (SD=1.30). The majority of patients admitted received a discharge diagnosis of a major depressive disorder (57%) and the mean length of stay was 11.14 days (SD=7.75). Of the patients admitted, 85% did not appear to have sexual health questions asked on admission and 61% did not have any documented sexual health questions asked throughout their inpatient admission. 17% of patients had sexual activity information documented and very few patients had any STI screening or pregnancy testing (9 patients and 14 patients, respectively).
CONCLUSION: Adolescents with major mental health disorders may be at increased risk for risky sexual behaviours. We found that sexual health practices were only addressed in a minority of patients during their inpatient psychiatric admission. This interaction with the health care system represents an underutilized opportunity to provide counselling and anticipatory guidance to adolescents regarding their sexual health.

Abstract
INTRODUCTION Gemcitabine-induced thrombotic microangiopathy is a rare event whose management is not yet consensual. The use of eculizumab could be of interest. CASE REPORT A 68-year-old woman was treated by gemcitabine as adjuvant chemotherapy of a pancreatic adenocarcinoma. Two months later, the patient presented with mechanical hemolytic anemia, thrombocytopenia and high blood pressure that led to the diagnosis of thrombotic microangiopathy. Gemcitabine was stopped. Plasma exchange therapy was introduced since hematological and renal parameters had worsened. As clinical efficacy was insufficient, eculizumab was introduced at a dose of 900 mg per week 4 times, then 1200 mg every 2 weeks. Symptoms along with hematological and nephrological analysis were back to physiological standards after 7 intravenous injections. CONCLUSION Eculizumab seems to be an effective treatment against gemcitabine-induced thrombotic microangiopathy in case of severe hematological and renal injuries associated with a lack of response to plasma exchange therapy.

Abstract
In the last decade, several studies have emphasised the need to understand and optimise the computed tomography (CT) procedures in order to reduce the radiation dose applied to paediatric patients. To evaluate the influence of the technical parameters on the radiation dose and the image quality, a statistical model has been developed using the design of experiments (DOE) method that has been successfully used in various fields (industry, biology and finance) applied to CT procedures for the abdomen of paediatric patients. A Box-Behnken DOE was used in this study. Three mathematical models (contrast-to-noise ratio, noise and CTDI vol) depending on three factors (tube current, tube voltage and level of iterative reconstruction) were developed and validated. They will serve as a basis for the development of a CT protocol optimisation model.

Abstract
Estetrol (E4) is a natural estrogen produced exclusively by the human fetal liver during pregnancy. Its physiological activity remains unknown. In contrast to ethinyl estradiol and estradiol (E2), E4 has a minimal impact on liver cell activity and could provide a better safety profile in contraception or hormone therapy. The aim of this study was to delineate if E4 exhibits an activity profile distinct from that of E2 on mammary gland. Compared with E2, E4 acted as a low-affinity estrogen in both human in vitro and murine in vivo models. E4 was 100 times less potent than E2 to stimulate the proliferation of human breast epithelial (HBE) cells and murine mammary gland in vitro and in vivo respectively. This effect was prevented by fulvestrant and tamoxifen, supporting the notion that ERα (ESR1) is the main mediator of the estrogenic effect of E4 on the breast. Interestingly, when E4 was administered along with E2, it significantly antagonized the strong stimulatory effect of E2 on HBE cell proliferation and on the growth of mammary ducts. This study characterizes for the first time the impact of E4 on mammary gland. Our results highlight that E4 is less potent than E2 and exhibits antagonistic properties toward the proliferative effect of E2 on breast epithelial cells. These data support E4 as a potential new estrogen for clinical use with a reduced impact on breast proliferation.

Abstract
UNLABELLED HTA Vasc offers an approved educational program for hypertensive patients at high cardiovascular risk (CVR). METHOD A telephone survey (December 2011-July 2012) evaluated the benefits of different workshops "my treatment", "my blood pressure" and "my nutrition", more than 6 months after the end of the program. The follow-up data (TS) were compared to inclusion data (T0) and to final data (TF) in 73 hypertensive patients. RESULTS The follow-up period was 6 to 31 months. The number of hypertensive controlled patients [blood pressure (BP)<140/90 mmHg] increased from 55.4% to 75.4% (P=0.0158) in TF, which remained over time. The practice of physical activity increased from 47.9% (T0) to 79.5% (TS) (P=0.001). The follow-up period of 18 months or more was associated with a tendency to weight gain (P=0.0059) and with a decline in physical activity [89.7% (<18 months) to 67.5% (≥ 18 months) (P=0.0198)]. The practice of self-measurement BP increased from 41.1% (T0) to 71.2% (TS) (P<0.0001); knowledge of the "rule of three" increased from 6.8% (T0) to 74% (TS) (P<0.0001). CONCLUSION An educational support contributes to a better long-term BP control. The motivation for lifestyle rules decreases with time. The implementation of a structured motivational follow-up could maintain the lifestyle motivation at these CVR patients.

Abstract
PURPOSE This document presents a systematic and structured approach for functional modeling for risk analysis in radiotherapy, aiming to reconcile the need, on one hand, for a method that can be applied generally and, on the other hand, for a method that provides a highly precise model. MATERIALS AND METHODS The approach relies on new functional structuring patterns and flux analysis, derived from system engineering and knowledge engineering. RESULTS The method affords strong support for the development of detailed models of the patient's process through a department of radiotherapy. Lack of structure of the actual process in a particular department may be easily identified leading to the development of specific procedures for the improvement of security. CONCLUSION Modeling approach derived from engineering may be used for functional modeling for risk analysis in radiotherapy.

Abstract
Peritumoral Lymphatic Vessel Density (LVD) is considered to be a predictive marker for the presence of lymph node metastases in cervical cancer. However, when LVD quantification relies on conventional optical microscopy and the hot spot technique, interobserver variability is significant and yields inconsistent conclusions. In this work, we describe an original method that applies computed image analysis to whole slide scanned tissue sections following immunohistochemical lymphatic vessel staining. This procedure allows to determine an objective LVD quantification as well as the lymphatic vessel distribution and its heterogeneity within the stroma surrounding the invasive tumor bundles. The proposed technique can be useful to better characterize lymphatic vessel interactions with tumor cells and could potentially impact on prognosis and therapeutic decisions.

Abstract
In February 2007, the radiation therapy department of the Jean Monnet Hospital in Epinal (France) has stopped the radiotherapy treatments after the discovery of a radiotherapy accident and bad practices leading to overexposure of patients between 1987 and 2006. The Regional Cancer Center "Centre Alexis Vautrin" in Nancy (France) was given the task of the new start of treatment activity. From February 2007 to January 2008, actions of training, updates of equipments and practices have been performed in the Epinal Hospital, guided by the quality approach, allowing the treatment of new patients in February 2008, with the radiation oncologists and the medical physicists of the Centre Alexis Vautrin, with the highest conditions of security and confidence.

Abstract
OBJECTIVES The ADAMs (a disintegrin and metalloproteinase) enzymes compose a family of membrane-bound proteins characterized by their multi-domain structure and ADAM-12 expression is elevated in human non-small cell lung cancers. The aim of this study was to investigate the roles played by ADAM-12 in critical steps of bronchial cell transformation during carcinogenesis. MATERIALS AND METHODS To assess the role of ADAM-12 in tumorigenicity, BEAS-2B cells were transfected with a plasmid encoding human full-length ADAM-12 cDNA, and then the effects of ADAM-12 overexpression on cell behaviour were explored. Treatment of clones with heparin-binding epidermal growth factor (EGF)-like growth factor (HB-EGF) neutralizing antibodies as well as an EGFR inhibitor allowed the dissection of mechanisms regulating cell proliferation and apoptosis. RESULTS Overexpression of ADAM-12 in BEAS-2B cells promoted cell proliferation. ADAM-12 overexpressing clones produced higher quantities of HB-EGF in their culture medium which may rely on membrane-bound HB-EGF shedding by ADAM-12. Targeting HB-EGF activity with a neutralizing antibody abrogated enhanced cell proliferation in the ADAM-12 overexpressing clones. In sharp contrast, targeting of amphiregulin, EGF or transforming growth factor-alpha failed to influence cell proliferation; moreover, ADAM-12 transfectants were resistant to etoposide-induced apoptosis and the use of a neutralizing antibody against HB-EGF activity restored rates of apoptosis to be similar to controls. CONCLUSIONS ADAM-12 contributes to enhancing HB-EGF shedding from plasma membranes leading to increased cell proliferation and reduced apoptosis in this bronchial epithelial cell line.
