Surgery in ovarian cancer - Brazilian Society of Surgical Oncology consensus.

Surgical management in epithelial ovarian cancer (EOC) has a significant impact in overall survival and progression-free survival. The Brazilian Society of Surgical Oncology (BSSO) supported a taskforce of experts to reach a consensus: experienced and specialised trained surgeons, in cancer centres, provide the best EOC surgery. Laparoscopic and/or radiological staging prognosticates the possibility of complete cytoreduction (CC0) and helps to reduce unnecessary laparotomies. Surgical techniques were reviewed. Multidisciplinary input is essential for treatment planning. Quality assurance criteria are proposed and require national consensus. Genetic testing is mandatory. This consensus states the final recommendations from BSSO for management of EOC. TWEETABLE ABSTRACT: Brazilian Society of Surgical Oncology consensus for surgery in epithelial ovarian cancer patients.

Valor nutritivo de pastagens de Coastcross-1 em consórcio com diferentes leguminosas de ciclo hibernal / Nutritive value of coastcross-1 pastures mixed to different cool season legumes

Objetivou-se com esta pesquisa avaliar três sistemas forrageiros constituídos por Coastcross-1 (CC) + 100kg de N/ha/ano + ervilhaca comum; CC + 100kg de N/ha/ano + trevo vesiculoso; e CC + 200kg de N/ha/ano. Durante o período experimental (345 dias), foram realizados treze pastejos. O delineamento experimental utilizado foi o inteiramente ao acaso, com três tratamentos (sistemas forrageiros), três repetições (piquetes) em parcelas subdividas no tempo (valores médios dos pastejos em cada estação do ano). Para avaliação, foram utilizadas vacas em lactação da raça Holandesa. Amostras de simulação de pastejo foram coletadas para análise de proteína bruta (PB), fibra em detergente neutro (FDN) e ácido (FDA), digestibilidade in situ da matéria seca (DISMS) e da matéria orgânica (DISMO) e os nutrientes digestíveis totais (NDT). Os valores médios para PB, FDN, FDA, DISMS, DISMO e NDT foram de 18,1; 16,7 e 17,6%; 57,8; 58,9 e 58,7%; 26,5; 26,5 e 26,7%; 79,6; 78,9 e 80,6%; 79,8; 79,1 e 80,6%; 72,1; 71,4 e 72,7%, respectivamente. Melhores resultados de valor nutritivo foram obtidos no inverno, em especial para o consórcio de Coastcross-1 com ervilhaca.(AU)

The aim of this research was to evaluate three grazing systems with Coastcross-1 (CC) + 100kg N/ha/year + common vetch; CC + 100kg N/ha/year + arrowleaf clover; and CC + 200kg N/ha/year. Thirteen grazing cycles were performed during the experimental period (345 days). The experimental design was completely randomized with three treatments (grazing systems), three replicates (paddocks) in completely split-plot time (average values of grazing season). Lactating Holstein cows were used in the evaluation. Forage mass and botanical composition were evaluated. Samples from the hand-plucking method were collected to analyze crude protein (CP), neutral detergent fiber (NDF) and acid (ADF), in situ digestibility of dry matter (ISDMD) and organic matter (ISOMD) and total digestible nutrients (TDN). The averages of CP, NDF, ADF, ISDMD, ISOMD and TDN were 18.1, 16.7 and 17.6 %; 57.8, 58.9 and 58.7 %; 26.5, 26.5 and 26.7 %; 79.6, 78.9 and 80.6 %; 79.8, 79.1 and 80.6 %; 72.1, 71.4 and 72.7 %, respectively. Better results for nutritive value were found during winter, especially on Coastcross-1 mixed with common vetch.(AU)

Efeito da adubação nitrogenada na produção de forragem, teor de proteína bruta e taxa de lotação em pastagens de azevém / Effect of nitrogen fertilization on the forage production, crude protein content and stocking rate of ryegrass pastures

O objetivo desta pesquisa foi avaliar a produção e o teor de proteína bruta da forragem de três pastagens de azevém (Lolium multiflorum Lam) cv. Comum, adubadas com 50, 100 e 150 kg de N/ha, na forma de ureia, de maio a outubro de 2012, onde foram conduzidos cinco ciclos de pastejo. Na avaliação da pastagem de azevém foram usadas vacas da raça Holandesa (530 kg PC) que receberam diariamente suplementação alimentar de 4,5 kg de concentrado. Avaliou-se a massa de forragem no pré e no pós-pastejo, a composição botânica e estrutural do azevém, e a taxa de lotação. Foram coletadas amostras de forragem pelo método de simulação de pastejo para análise de proteína bruta. O delineamento experimental foi o inteiramente casualizado com três tratamentos (níveis de N) e três repetições (piquetes). Os valores médios para produção de forragem, teor de proteína bruta e taxa de lotação foram: 4827; 6344 e 6123 kg/ha; 20,17; 21,51 e 22,82%; 2,3; 2,95 e 3,32 UA/ha para os tratamentos de 50, 100 e 150 kg de N/ha, respectivamente.

The objective of this study was to evaluate the forage production and crude protein content of three ryegrass stands (Lolium multiflorum Lam. cv. Comum) fertilized with 50, 100 and 150 kg N/ha in the form of urea from May to October 2012. Five grazing cycles were conducted. Holstein cows (530 kg body weight) supplemented daily with 4.5 kg concentrate were used for the evaluation of ryegrass pasture. Pre- and post-grazing forage mass, the botanical and structural composition of ryegrass, and stocking rate were evaluated. Forage samples were collected by the pasture simulation method for the analysis of crude protein. A completely randomized experimental design consisting of three treatments (N levels) and three repetitions (paddocks) was used. The mean forage production, crude protein content and stocking rate were 4827, 6344 and 6123 kg/ha; 20.17, 21.51 and 22.82%, and 2.3, 2.95 and 3.32 AU/ha for the treatments with 50, 100 and 150 kg N/ha, respectively. The maximum nitrogen level recommended is 100 kg N/ha...(AU)

[Comparison of 2 artificial insemination technics. (Sperm tubal perfusion and intrauterine insemination)]. / Comparación de dos técnicas de inseminación artificial. (Perfusión tubárica de esperma e inseminación intrauterina).

In 1991 Kahn et al, described a method of intrauterine Insemination called Fallopian Tube Sperm Perfusion (FSP) using 4.0 ml for the insemination volume, unlike the classic Intrauterine Insemination (IIU) in which insemination volume is 0.5 ml. The aim of this study is to compare pregnancy rate per cycle in both technics. Between August 1993 and January 1994, 60 couples with infertility were studied, 131 ovarian stimulation cycles were done, 95 with IIU and 36 with PTE. 18 clinical pregnancies occurred, 11 with IIU and 7 with PTE, for a pregnancy rate per cycle of 11.5% for IIU and 19.4% for PTE. This result confirms the reports by Kahn. PTE represents a new possibility for the treatment of different etiology infertility.
