This study aimed to evaluate energy and nutritional densities, water, carbon and ecological footprints, cost, of omnivorous and vegan main courses served in a university restaurant in the city of Rio de Janeiro. A cross-sectional, analytical study was conducted with 40 main dish-type preparations, 20 of which are omnivorous and 20 vegans, served at lunch, to assess energy and nutritional densities, carbon, water and ecological footprints and cost of preparations. We propose a healthy and sustainable preparation index (HSPI) to evaluate from the list, the best preparation options considering the nutritional quality combined with the impact that the food causes on the environment. Preparations with the highest HSPI were considered the best options because they have a good relation between the nutritional profile and the environmental impact. Results: Regarding energy (ED), nutritional (ND) densities and water, carbon and ecological footprints, omnivorous preparations presented much higher values when compared to the vegan ones. The omnivorous preparations had the highest average cost (R$ 3.44). Regarding the HSPI, vegan preparations showed better rates than omnivorous preparations. Food services should promote healthy and sustainable choices by offering menus with low energy density preparations, high nutritional density, and low environmental impact, considering local realities and customer needs. Conclusion: This study was able to evaluate the best preparation options, considering the nutritional profile and the food impact on the environment, using health and sustainable indicators. Obtaining indicators of preparations regarding healthiness and sustainability, in practice, translates environmental aspects in menu planning, which contribute to changes in food consumption patterns in food services, in addition to contributing to the reduction of the environmental impact. In this way, they can be used as tools added to the menu planning process for the analysis of the

Objective: To understand, based on the life narratives of refugee women, food and nutritional security. Method: Qualitative, descriptive, exploratory study, Narratives of life method, by Daniel Bertaux. Conducted with 11 participants, refugee women residing in the state of Rio de Janeiro, Brazil. Results: The meanings and feelings evidenced in the life narratives of refugee women expressed the insecurities and weaknesses with food in the resettlement. Final Considerations: Given the meanings and feelings regarding food in the refuge, it is expected that the present study will contribute to the elaboration of new action plans and intersectoral public policies of agile action to meet the demands of the refugee population, in the attempt to mitigate starvation, poverty, social differences and the compromised health status of the refugee population.

Intimate partner violence(IPV)is simultaneously assumed as a serious crime and a major public health issue,having recurrences as one of its main characteristics and,consequently,re-entries of some alleged offenders in the criminal justice system(CJS).The main goal of this study is to assess if in cases of female victims of IPV,violence decreases after the first entry of the alleged offender in the CJS.A retrospective study was performed based on the analysis of police reports of alleged cases of IPV during a 4-year *** final sample(n=1488)was divided into two groups according to the number of entries in the CJS(single or multiple)followed by a comparative *** suggest that violence decreases after the first entry of alleged offenders in the ***-entries were found in only 15.5%of the cases but they were accountable for 3.3 times more crimes on ***,victims of recidivism presented more injuries and required more medical ***,a small group of alleged offenders seems to be more violent and accountable for most of the IPV crimes registered in the CJS suggesting that regardless of legal sanctions aiming to deter violence,these measures may not be enough for a certain group of *** study sustains the need for a predictive model to quantify the risk of repeated IPV cases within the Portuguese population.

Elaeis guineensis (African oil palm) and E. oleifera (American oil palm) are bred to attain high oil yields, disease resistances, and decelerated shoot elongation. We cultivated immature zygotic embryos from backcrossed and F1 interspecific progenies on media containing 110, 150, or 200 mg·l-1 2,4-diclorophenoxyacetic acid (2,4-D) to obtain embryogenic cultures. These were set to multiply on medium containing 8 mg·l-1 2,4-D or lower concentrations of auxins and finally we induced plantlets regeneration, from each zygotic embryo, independently, in order to have the clones organized according to their respective origins. Reductions in auxins induced cultures to revert from highly embryogenic into competent for embryogenesis and finally to organogenic degenerated callus lines. Histology and the expression of SOMATIC EMBRYOGENESIS RECEPTOR KINASE, DEHYDRIN, DEFENSIN, TRANSPOSASE, and LIPID TRANSFER PROTEIN were analyzed on four callus lines representative of morphological aspects consistently observed. The highest number of embryogenic cultures was obtained on 150 mg·l-1 2,4-D. Maturation and multiplication of somatic embryos through secondary embryogenesis occurred simultaneously on 8 mg·l-1 2,4-D. LIPID TRANSFER PROTEIN expression was detected in one of the embryogenic cultures and correlated with protoderm onset. Three six-week cycles on induction medium yielded 1.5 shoots above 6 cm per poly-embryogenic complex, which performed better than embryoids individualized mechanically. Rooting was observed for 77% and 82% of shoots from these two types of explants, respectively. Rooted plantlets ready for acclimatization were obtained nine months after shoot

Topotecan Use for Second-Line Treatment in Patients with Recurrent or Metastatic Cervical Cancer at Brazilian National Cancer Institute (INCA)

引用

Journal of Cancer Therapy 2013年第6期4卷 1095-1099页

作者： Leandro Nascimento de Oliveira Flávia vieira guerra Alves Paulo Alexandre Ribeiro Mora Claudio Calazan do Carmo Angélica Nogueira-Rodrigues Alvaro Henrique Ingles Garces Andréia Cristina de Melo Instituto Nacional do Cancer Hospital do Cancer II Rio de Janeiro-RJ Brazil

Objective: Cervical cancer represents the third most commonly diagnosed cancer and is an important cause of death for women suffering with malignancies. Patients who are refractory or progressed after first-line palliative treatment have a dismal prognosis and no second-line chemotherapy is considered standard so far. Several agents have been investigated in this setting and topotecan is one of the most characterized. The objective of this study was to evaluate response rate (RR), progression-free survival (PFS), overall survival (OS) and toxicity of topotecan in second palliative line for cervical cancer. Methods: An analysis was performed of all patients with recurrent or metastatic cervical cancer treated with topotecan in second palliative line at Brazilian National Cancer Institute, between 2008 and 2010. Results: A total of 73 courses of topotecan were given in the current study (median: 3.5 cycles;range 1 - 6). Anemia was the most frequent adverse event (grade 2:35%;grade 3:30%). Of the 20 patients evaluable, there were 2 partial responders to the treatment. The overall response rate (ORR) was 10%;3 patients (15%) had stable disease as maximum response. The median PFS for the entire group was 2.93 months (95% CI 2.41 - 3.45) and OS was 4.66 months (95% CI 1.21 - 8.11). Conclusion: The limited activity of topotecan schemas in second-line treatment of cervical cancer and the associated overall toxicity may not justify their use in this setting. Patients who progress after first-line treatment may be offered participation in clinical trials, other second-line agents or best supportive care measures.
