AIM: To review the characteristics of hematological malignancies in tropical areas, and to focus on the specific difficulties regarding their management. METHODS: This is a retrospective narrative review of cases of patients with hematological malignancies. All medical files of patients with malignant disease whose treatment was coordinated by the HematoOncology service of the Cayenne Hospital in French Guiana between the 1st of January 2010 and the 31 st of December 2012 were reviewed. Clinical data were extracted from the medical files and included: Demographic data, comorbidities, serological status for human immunodeficiency virus, human T-lymphotropic virus 1(HTLV1), hepatitis b virus and hepatitis C virusinfections, cytology and pathology diagnoses, disease extension, treatment, organization of disease management, and follow-up. The subgroup of patients with hematological malignancies and virus-related malignancies were reviewed. Cases involving patients with Kaposi sarcoma, and information on solid tumor occurrence in virus-infected patients in the whole patient population were included. Since the data were rendered anonymous, no informed consent was obtained from the patients for this retrospective analysis. Data were compiled using EXCEL® software, and the data presentation is descriptive only. The references search was guided by the nature of the data and discussion. RESULTS: In total, the clinical files of 594 patients(pts) were reviewed. Hematological malignancies were observed in 87 patients, and Kaposi sarcoma in 2 patients. In total, 70 patients had a viral infection, and 34 of these also had hematological malignancies. The hematological diagnoses were: Multiple myeloma in 27 pts, lymphoma(L) in 43 pts, myeloproliferative disorders in 17 pts and Kaposi sarcoma in two patients. The spectrum of non-Hodgkin lymphomas(NHL) was: burkitt L(1 pt), follicular L(5 pts), chronic lymphocytic leukemia(5 pts), high-grade NHL(9 pts), mucosa-associated lymphoid

Does food addiction distinguish a specific subgroup of overweight/obese overeating women?

Neurophysiological and behavioral similarities have been evidenced between excessive food consumption leading to obesity and addiction to other substances. In accordance, food addiction was defined following the DSM-IV diagnostic criteria for substance dependence. The aim of this pilot study was to identify a subgroup of women suffering from food addiction (n = 11), and to compare them to women suffering from substance-use disorder (n = 23), and to women seeking treatment for compulsive overeating but free from food addiction (n = 12) on addiction-related characteristics (reward sensitivity, impulsivity, personality traits, depression, emotion dysregulation). We hypothesized that women with food addiction would be similar to women with substance-use disorders, and different from women with compulsive overeating without food addiction. Participants completed self-reported questionnaires assessing food addiction and other variables related to addiction. Almost half (47.8%) of women with compulsive overeating fulfilled the criteria for food addiction. Although food addiction does not account for every case of compulsive overeating, it characterizes a specific subgroup of overweight/obese women who show more severe overeating. Women with food addiction seem to be more similar to women suffering from substance-use disorders than to other women with overeating difficulties, particularly regarding impulsivity and self-directedness.

Objective: To determine the psychosocial problems, social acceptance and the impact of the costs of parents whose child has cancer. b>Method: b>We carried out a descriptive cross-sectional study over two-year periods (from January 3, 2018 to March 31, 2020) in the pediatric oncology unit of clinics at the University of Lubumbashi, in DR Congo. b>Results:b> 129 parents of children with cancer in the pediatric oncology unit were included in our study. Most children with cancer (53%) were accompanied by their mothers who had a low level of education (53.0%). Emotional shock was the most observed reaction (68%) to the announcement of the disease (cancer). Retinoblastoma has had a significant economic impact on families without medical coverage. Only 38% received psychological support from parents. Sadness was the most common feeling (77%) of households. Support workers consider their relationship with the medical profession acceptable in 67% and difficult in 11%. The majority of parents (78%) felt that the time to provide medical care was longer than expected. b>Conclusion: b>Parents of children with cancer had different feelings and reactions. This observation may be useful for the development of a health policy, in particular that of pediatric cancer in DR Congo.

Corrosion by a Heavy Metal Oxide Glass

引用

Journal of Materials Science & Technology 2005年第2期21卷 243-245页

作者： b.b.Rana Department of Engineering Materials University of Sheffield Sheffield S1 4DU UK PCSIR Laboratories Complex LahorePakistan

Melts of lead bismuth gallate compositions are highly corrosive and attack on crucibles of different materials. In the present study, corrosion by a base glass (50PbO-30bi2O3-20Ga2O3 in mole fraction) melted using different crucibles and the effect on UV-VIS and IR edges were studied. by melting the base glass in platinum/2% rhodium, gold zirconia and alumina crucibles showed less effect on the IR edge and therefore shifted the infrared edge to longer wavelength, whereas silica crucible contaminated the glass, causing a severe deterioration in the infrared and hence shifted infrared edge to much shorter wavelength. In the UV-VIS region, base glass melted in platinum/2% rhodium crucible shifted the edge to the longest wavelength whereas silica crucible shifted the edge to shorter wavelength. The contaminants from gold, zirconia and alumina crucibles caused the UV-VIS edge of the base glass to lie between the two extremes of Pt/2% Rh and SiO2 crucibles. The glasses melted in above mentioned crucibles were also characterized with inductively coupled plasma spectroscopy (ICP) analysis to measure the level of contamination from the crucibles. Depending upon crucible used, the colors of glasses obtained ranged from red to yellow.

由于二叠纪罩笼虫化石材料极度稀缺,我们对罩笼虫从古生代向中生代类型演化的过程仍然一无所知。本文在广西晚二叠世大隆组与领薅组中报道了少量疑似罩笼虫化石。它们的形态简单,与三叠纪的罩笼虫属bipedis形态相似,但缺少外饰,可能是中生代罩笼虫的先驱分子。如果本文描述的这些?bipedis化石真属于罩笼虫目,那么该目从石炭纪晚期到二叠纪的演化可能经历了一段形态简化的阶段;在早三叠世,伴随其辐射过程,它们的形态也开始逐渐变得复杂。这些化石形态上介于古生代和中生代的罩笼虫之间,它们在吴家坪阶-长兴阶界线附近的出现可能是二叠-三叠纪之交深水放射虫由阿尔拜虫向罩笼虫动物群转变的序曲。

Nonsmooth Semi-Infinite Minmax Programming Involving Generalized(Φ, ρ)-Invexity

引用

Journal of Systems Science & Complexity 2015年第4期28卷 857-875页

作者： UPADHYAY b b MISHRA S K Department of basic Sciences & Humanities National Institute of Technology

This paper introduces some new generalizations of the concept of （~, p）-invexity for non- differentiable locally Lipschitz functions using the tools of Clarke subdifferential. These functions are used to derive the necessary and sufficient optimality conditions for a class of nonsmooth semi-infinite minmax programming problems, where set of restrictions are indexed in a compact set. Utilizing the sufficient optimality conditions, the authors formulate three types of dual models and establish weak and strong duality results. The results of the paper extend and unify naturally some earlier results from the literature.
