Journal of Cancer Therapy 2014年第14期5卷 1332-1343页

Background: The standard therapy in advanced hepatocellular carcinoma (HCC) is sorafenib (SOR), which has the inconvenience of toxicity and discontinuation. Patient selection and the use of early markers are critical for optimizing the potential benefit of SOR. Alpha-fetoprotein (AFP) has an established role in HCC prognosis. The objective was to evaluate whether AFP variation during SOR treatment reflects the lack of progression to SOR and can be used as a prognostic factor. Methods: AFP levels were prospectively analyzed in 114 patients to determine whether the time to progression of AFP (TPA) at 3 months had a prognostic value for survival. Results: Between July 2007 and October 2012, 114 patients were included (mean age 64 years, 97 male, 96 with cirrhosis). Etiology was alcohol 47 (41%) and hepatitis C virus (HCV) 31 (27%). According to the Barcelona Clinic Liver Cancer (BCLC) staging system: A (one case), B (24 cases) and C (89 cases). The Child-Pugh was Class A in 89 cases. The general condition of the patient according to ECOG-PS was 0 in 73 cases. The median duration of treatment was 5 months (3.47 - 6.53, 95% CI). The median overall survival (OS) was 9.23 months. The standard dose was maintained in 26 patients (22.8%). Sixty-seven percent of patients experienced at least one adverse event grade 3-4. The time to progression of AFP lower or higher than 3 months was an independent prognostic factor of OS (univariate and multivariate analysis): 8.10 vs. 18.85 months, P 3 months had longer OS, and TPA was an independent prognostic factor.

Associated or Concomitant Diseases Influence Significantly the Health-Sickness Concept in Celiacs

引用

Open Journal of Epidemiology 2017年第2期7卷 139-158页

It is well-known that feeling to be a healthy or sick person most probably results from the mind than from the body. We all know healthy people who feel sick and vice versa. We were interested in the health and sickness feeling of celiac people, their autorating of these feelings and its conditioning factors as well as their expectations. In this paper we present the results of an inquiry to evaluate these situations. We performed a descriptive, transversal and prospective study for 2 years to groups of celiacs and their families. They received a closed inquiry to be completed before the beginning of the talk. The inquiry included personal data and the co-existence of associated or concomitant (AoC) diseases. Most of the sample’s patients felt to be a healthy person (86.8%). Mothers see their children as healthy and the auto rated criteria is significantly better than the adult celiac person (“t”= -6.024 (p = 0.000)). AoC diseases influenced negatively in the feeling of being healthy and strongly decreased the autorating. Longer time passed on treatment reflects an increase feeling of health and of the autorating. In people with AoC diseases and who feel sick, the increased time of treatment did not show significant differences. People with “gluten sensitivity” felt sicker and auto rated themselves with a lower number than celiacs. Many pediatric gastroenterologists notice that the newly agreed definition of celiac disease, referring it as “autoimmune, chronic, incurable, and multisystemic”, results in a very negative character of the condition which might compromise the future labour of this people as well as their admittance to different health insurance systems.

Analysis of the Per Capita Generation of Municipal Solid Waste by Socioeconomic Strata in Veracruz, Mexico, Using a Statistical Experimental Design

引用

Journal of Chemistry and Chemical Engineering 2012年第2期6卷 138-146页

作者： lorena de Medina-Salas Eduardo CastiUo-gonzalez Rabindranarth Romero-Lopez Luis Omar Jamed-Boza Chemical Engineering School University Veracruzana Xalapa 91040 Veracruz Mexico Civil Engineering School University Veracruzana Xalapa 91040 Veracruz Mexico

The management of municipal solid waste (MSW) is currently one of the major environmental concerns in Mexico. Therefore, municipalities must develop local programs for prevention and integrated management of MSW based on the data of MSW generation; however, these are scarce and diffuse. It is known that the MSW generation is affected by many factors, including life level. Given the importance of having reliable data, the objective of this study was to determine the per capita MSW generation of a small urban locality in the state of Veracruz and test whether there were significant statistic differences of per capita MSW generation among the life levels. The households were randomly sampled according to the Mexican standard of reference and were classified as popular, middle and residential. The per capita MSW generation determined was 0.355 kg·inhab-1·day-1. This value was lower than the value estimated by the national reference, suggesting that it might be overestimated and consequently lead to errors in estimating installations costs for the MSW treatment. The result of the experimental design revealed that there were significant statistic differences in the per capita MSW generation among the three socioeconomic strata. This study will allow the municipality to establish better strategies within the municipal program and differential rate for the provision of public clean service and it also provides a solid basis for future research under similar conditions.

肠道微生物群是生活在我们肠道中的微生物的集合,它们的基因组被称为微生物组。这种微生物群的正确组成和功能对于保持"健康状态"是必不可少的。衰老与肠道微生物群的变化有关,肠道微生物群的变化常常与胃肠道的生理改变有关,也与饮食模式的改变有关,并且伴随着认知和免疫功能的下降,这些都是造成虚弱的原因。因此,旨在恢复老年人微生物群的营养战略必须从全局出发,不仅要考虑微生物群,而且要考虑其他肠道外的作用靶点。本综述旨在总结老年人肠道微生物群改变和其他功能受损的最新知识,并通过使用益生菌、益生元或特定营养素来分析实施营养策略的工具,以平衡这些变化。老年人的疾病和功能损害和肠道微生物的变化密切相关,营养影响微生物群的形成;因此,提高对老年人中营养与肠道菌群结构和功能之间相互作用的认识,可以通过设计个性化营养策略来帮助改善老年人群的总体健康状况。

The aim of this study was to identify the most frequent yeasts in the oral cavity of adult individuals without immune disorders and to associate the presence of these oral yeasts with different characteristics of each individual. Oral rinse samples were obtained from 96 healthy adults and cultured in Sabouraud dextrose agar media and CHROMagar. Yeasts were identified by sequencing the D1/D2 region of the 28 S rRNA gene. Probable association among the socio-demographic characteristics, body mass index, family and personal medical history,oral hygiene, tobacco and/or alcohol consumption habits and presence of oral fungi was analyzed. Contingency tables and logistic regression were employed to evaluate possible relationships between the presence of oral fungi and mixed colonization with these variables. 57.3% of the healthy individuals had oral yeasts and 21.8% had mixed colonization. The most prevalent yeasts were Candida albicans(52%), C. parapsilosis(17.9%), and ***(7.57%). Yeasts with most frequently mixed colonization were C. albicans and C. parapsilosis. No relationships were found among the variables analyzed. However, the presence of mixed colonization was related to the presence of dental prostheses(P<0.006), dental apparatuses(P=0.016) and O’Leary index(P=0.012). This is the first study that characterized oral yeasts in Colombian healthy individuals, determined the most prevalent oral yeasts C. albicans, C. parapsilosis and C. dublinensis and an association of mixed colonization with the use of dental prostheses and aparatology and poor hygiene.
