Background: We aimed to describe addictive behaviours and identify risk factors for addiction among students in their first year of university, which is known to represent a stressful situation conducive to the emergence of addictive behaviours. Methods: Ongoing cross-sectional survey among first-year students of the University of Reims Champagne-Ardenne (france). The first 16 months of the survey, which is due to run for 5 years, are analysed here. A self-report questionnaire was proposed to all first-year students during their mandatory preventive medicine consultation. The questionnaire kit comprised validated questionnaires evaluating addiction to alcohol, tobacco, cannabis, cocaine, amphetamines, solvents, tranquillizers, hallucinogens, opiates, other drugs, internet, and gambling or games of chance. Results: In total, 1139 students were included in this analysis;participation rate was 94% among all those invited to participate. Average age was 19 ± 1 years, male to female sex ratio was 0.54. Among respondents, 18% were at risk of addiction to alcohol, 2.3% were addicted;19.6% were smokers, and 5.5% were dependent. Cannabis was the most frequently used illicit substance, with 4.8% of students at risk, and 2 subjects addicted. For the internet, 11.6% of subjects were at risk, and 1.4% were addicted. By logistic regression, students receiving grants or whose parents have a low socio-professional category were at less risk of addiction to alcohol. We also found that students at risk were less likely to accept treatment. Conclusion: These initial findings show that certain addictive behaviours are particularly prevalent among first-year students, with identifiable risk factors or protective factors, thereby opening avenues for preventive and therapeutic measures.

Objective: To analyze the volumetric modifications of the non tumourous part of the liver when liver metastases (LM) decrease under chemotherapy. Methods: Patients were highly selected based on the following criteria: multiple bilateral large colorectal LM, response of LM attaining at least 85% under chemotherapy. The volumes and ratios of the whole liver, of the LM, and mainly of the non tumourous (normal) part of the liver, were measured on CT scan before and after chemotherapy. Results: Only ten (5%) among 198 treated patients were eligible. Nine of them had received intra-arterial chemotherapy. Metastatic involvement was initially 34% before chemotherapy (range: 13% - 75%), and was 5% (range: 1% - 25%) after chemotherapy. The whole liver volume decreased by 41% (range: 23% - 68%) after chemotherapy. The non metastatic liver (volume and ratio) decreased after chemotherapy in 6 patients and increased in 4 patients. The volume and ratio increased in the 4 patients whose disease initially exhibited the highest metastatic involvement (p = 0.01). Conclusion: The volume of the non metastatic part of the liver varied slightly under standard chemotherapy. Intra-arterial chemotherapy induces dramatic responses, but also liver injury which impairs liver regeneration. However increasing volumes were observed when initial tumour involvement was major.

China Ocean Engineering 2005年第2期19卷 225-234页

作者：廖迎娣张玮 P.Y.deschamps College of Ocean Hohai University Nanjing 210098 China Laboratoire d'Optique Atmosphérique UMR CNRS 8518 Université de Lille I 59655 Villeneuve d'Ascq France

The data of SeaWiFS (Sea-Viewing Wide Field-of-View Sensor), installed on SeaStar, has been used to generate SSC (suspended sediment concentration) of complex and turbid coastal waters in China. In view of the problems of the SeadAS (SeaWiFS data Analysis System) algorithm applied to China coastal waters, a new atmospheric correction algorithm is discussed, developed, and used for the SSC of East China coastal waters. The advantages of the new algorithm are described through the comparison of the results from different algorithms.

Open Journal of Preventive Medicine 2012年第3期2卷 272-278页

作者： Monat-descamps Caroline deschamps frederic department of occupational Health Medicine Faculty 51100 Reims france

Encephalopathy, extrapyramidal features, neurodegenerative diseases, and peripheral neuropathy are commonly encountered in presentations of occupational neurotoxic syndromes. Epidemiological findings have suggested the role of pesticides, solvents and metals on the onset and progression of neurological diseases. The aim of this review is to present clinical manifestations of occupational and environmental neurologic disorders, to discuss toxic’s implications of these conditions, and to give indications about occupational branches and main jobs concerned. Better to know and categorize the clinical manifestation of neurologic disorders and toxics implicated, will improve the clinical management of occupational neurologic diseases. We performed a research of studies, case reports and review, particularly among most recent, available into Pub Med databases about occupational and environmental neurologic disorders and main toxics incriminated.

Tidal Prediction in the Sea Scheldt (Belgium) Using a Combination of Harmonic Tidal Prediction and 1d Hydraulic Modeling

引用

Natural Resources 2014年第11期5卷 627-633页

作者： Joris Vanlede Leen Coen Maarten deschamps Flanders Hydraulics Research Antwerp Belgium

The vertical tide in the Sea Scheldt (Belgium) is predicted using a combination of harmonic tidal prediction and 1d hydraulic modeling. At Prosperpolder (a measurement station close to the dutch-Belgian border), four years of water level data (2009-2012) are analyzed to obtain the harmonic components at that location. The accuracy of the harmonic prediction is checked with a statistical analysis of an astronomical hindcast for 2009-2012 against measurements. An existing 1d hydraulic model of the tidally influenced part of the Scheldt estuary is cut off at Prosperpolder. The time series of tidally predicted water levels at Prosperpolder is used as a downstream boundary condition for the hydraulic model. In this way, a tidal prediction can be obtained for any location in the Sea Scheldt, also for locations where no harmonic components are available, whilst guaranteeing the consistency between the predicted time series.

Validation of the General <i>Health Questionnaire</i>(GHQ-12) adapted to a work-related context

引用

Open Journal of Preventive Medicine 2011年第2期1卷 44-48页

作者： francois-Xavier Lesage Sonia Martens-Resende frederic deschamps Sophie Berjot 不详

Introduction: The aim of this study is to test the factorial structure and the internal consistency of the 12-items General Health Questionnaire adapted to work-related psychological distress (GHQW). Methods: A validated french version of the GHQ-12 was used and transformed to remind of the occupational context. A sample of 1014 workers completed the GHQW. Internal consis- tency was assessed by Cronbach’s α coefficient. The factorial structure was extracted with an exploratory factorial analysis (EFA). Results: The EFA run on the data yield to a one- factor structure explaining 60.5% of the total variance of the scale. The Cronbach’s alpha showed a very good internal consistency of the scale (α = 0.94). Conclusion: The findings support that the GHQW is a reliable and valid instrument for measuring work-related psychological distress in workers. This work-related version could find some applications in epide-miological research at work, in the study of psychosocial risk factors and in the occupational health physi- cian’s daily activity.

文中提出了一种从空间估算大气总水汽含量的新方法。该方法是从一窄一宽两个光谱通道来观测地球表面,两光谱通道的中心都在水汽吸收最大处940nm附近的波长上。由于这些特征,两个通道测得的太阳辐射率之比不依赖于地面反射率,能得到一个沿光学路径的总水汽含量直接估计值。以这种概念为基础,我们设计并制作丁一台两通道辐射仪以检验该方法。采用新设备进行的机载试验证明,在海洋和陆地上晴空条件下该方法是可行的,然而在海洋上并且有深厚气溶胶层存在时用该方法所得的总水汽量可能估计偏低20％。尽管卫星微波方法可以在各种天气条件下使用,与之相比,我们的方法具有简便的优点,而且在陆地上微波辐射测量技术不适用。我们提出的方法可能是一种很有希望的、可用于陆地的备选方法。

Isolated Gross Hematuria or Associated to Acute Retention of Urine as a Sign of Urologic Malignant Pathology

引用

Journal of Health Science 2014年第1期2卷 56-61页

作者： Angel Tomas Ibanez Concejo Marco Antonio Castillo Juan Sanchez-Verde Bilbao Jorge Short Apellaniz Ambar deschamps Perdomo Joaquin Garcia Canete Emergency department Fundaeion Jimenez-Diaz Hospital Madrid 28760 Spain

The causes oflGH （Isolated gross hematuria）, as the only symptom or associated with ARU （acute retention of urine） caused by clots in the urinary tract in patients who do not have a previous diagnosis of urological malignant pathology and to study the immediate mortality in patients with that sign are described. A descriptive observational study of the etiologies of patients shows the above mentioned symptomatology from the 1 st of January to the 30th of June of 2008 in the Emergency department which received follow-up treatment up to december 2010. It also describes the mortality before the definitive diagnosis and the days between receiving attention in the Emergencies department and the diagnostic tests. One hundred and four cases with the criteria described above were evaluated. Of these, 20.0% turned out to have bladder, prostate or kidney cancer; the bladder being the most affected organ. Of all the pathology, benign and malignant, the most frequent one is the benign hypertrophy of the prostate （49.8% of the total）. Of the total, 4.8% of the patients died in the following weeks before finishing the diagnostic study. Isolated gross hematuria is a clinical symptom closely related to urological malignant pathology and it does not have an insignificant mortality rate in a short period of time. For these reasons it is necessary to accelerate the diagnostic tests as soon as the patient presents the symptom.
