Abstract Background: The morphology of endplate was considered to be one of the influencing factors of Cage subsidence after lumbar interbody fusion (LIF). Previous radiographic evaluations on endplate mostly used sagittal X-ray or MRI. Whereas, there are few studies on the CT evaluation of endplate and intervertebral space (IVS), especially the evaluation of coronal morphology and its influence on subsidence and fusion after LIF. We aimed to measure and classify the shapes of the endplate and IVS using coronal CT imaging and evaluate the radiographic and clinical outcomes of different shapes of the endplate/IVS following oblique lateral lumbar interbody fusion (OLIF).Methods：A total of 137 patients who underwent L4-5 OLIF combined with anterolateral fixation from June 2018 to June 2020 were included. The endplate concavity depth (ECD) was measured on the preoperative coronal CT image. According to ECD, the endplate was classified as flat (< 2 mm), shallow (2-4 mm), or deep (> 4 mm). The L4-5 IVS was further classified according to endplate type. The disc height (DH), DH changes，subsidence rate, fusion rate, and Oswestry Disability Index (ODI) in different endplate/IVS shapes were evaluated during 1-year follow up. Results: The ECD of L4 inferior endplate (IEP) was significantly deeper than that of L5 superior endplate (SEP) (4.20±1.07 vs 1.63±0.83, P < 0.001). Four types of L4-5 IVS were identified: shallow-shallow (16, 11.68%), shallow-flat (45, 32.85%), deep-shallow (32, 23.36%), and deep-flat (44, 32.12%). A total of 45 (32.85%) cases of cage subsidence were observed. Only one (6.25%) subsidence occurred in the shallow-shallow group，which was significantly lower than in the other three groups (19 shallow-flat, 6 deep-shallow, and 19 deep-flat ) (P < 0.05). Meanwhile，the shallow-shallow group had the highest fusion rate (15, 93.75%) and the highest rate of reach minimal clinically important difference (MCID) ODI among the four types. The shape of L4 IEP mainly affects the final fusion rate, which is higher in the shallow shape than deep ( OR=2.845, p=0.034). Conversely, L5 SEP mainly affects the rate of cage subsidence, which was flat shape higher than shallow (OR=4.364, p=0.001).Conclusion: The L4-5 IVS is an irregular shape that tends to be fornix-above and flat-down on coronal CT view. The shallow-shallow IVS has the lowest subsidence rate and best fusion result, which is possibly because it has a relatively good degree in matching either the upper or lower interface of the cage and endplates. These findings provide a basis for the further improvements in the design of the OLIF cage.

This paper explores techniques to quickly solve the maximum weight clique problem (MWCP) in very large scale sparse graphs. Due to their size, and the hardness of MWCP, it is infeasible to solve many of these graphs with exact algorithms. Although recent heuristic algorithms make progress in solving MWCP in large graphs, they still need considerable time to get a high-quality solution. In this work, we focus on solving MWCP for large sparse graphs within a short time limit. We propose a new method for MWCP which interleaves clique finding with data reduction rules. We propose novel ideas to make this process efficient, and develop an algorithm called FastWClq. Experiments on a broad range of large sparse graphs show that FastWClq finds better solutions than state-of-the-art algorithms while the running time of FastWClq is much shorter than the competitors for most instances. Further, FastWClq proves the optimality of its solutions for roughly half of the graphs, all with at least 105 vertices, with an average time of 21 seconds.

Esta leitura procura refletir sobre os investimentos intelectuais e afetivos de Boris Schnaiderman que movimentam os trânsitos culturais Brasil e Rússia, Verifica-se como a sua trajetória de tradutor intercultural desenvolveu-se no sentido de construir pontes de longo alcance que, com o passar dos anos, constituíram-se como um entrelugar marcado pelo saber e pela afetividade que passa a permear esses contatos. Observa-se também como Jerusa Pires Ferreira contracena com Boris Schnaiderman outra potente face das traduções culturais Brasil-Rússia, pelo viés da oralidade, dedicando-se ao estudo do conto russo no sertão baiano e construindo teias culturais duplamente marcadas pelo saber e pela afetividade.

The aim of study was verify the performance of athletes of the orientation sports. The sample was composed for ten athletes practices of modality, participants to Paulista Orientation Championship (CAMPOR/2016), with age to 21 and 30 years, from to competitor class “Category H21A” (mans over 21 years old), with road hard and intermediaries difficulty. Was utilized the “SPORTident” for attainment to results to performance to athletes during the competition. Was verify that athletes obtained the 1st and 35th places. Was showed that in some ware was verify more differences, fact that influenced in athltes, with velocity in 1,74 m/s for 1st and 1,24 for 35th . It is concluded that though from same category and has similar ages, the athletes evaluated showed differentiated results.

In the academic world, where we learn marketing theories and concepts, we take into consideration only the professional environment of large and medium-sized companies, not paying attention to the companies and entrepreneurs belonging to the base of the pyramid. The distance between the professional and the academic environments has already been proven in academic studies, however only taking into account the professional environment of large / medium enterprises. Thus, the gap between the academic environment and the environment where low-income entrepreneurs are inserted would be even greater. This study aims to better understand this distance, through comparative interviews of teachers and low-income entrepreneurs, in order to understand how low-income entrepreneurs can succeed even without academic education.

Analisar como a comunicação está sendo utilizada pelas agroindústrias da região da Alta Paulista para divulgar as ações de responsabilidade socioambiental para o fortalecimento da imagem organizacional é o objetivo deste artigo. Para coleta de dados realizou pesquisa de campo, com aplicação de formulários, junto a 59 agroindústrias da região da Nova Alta Paulista. Entre as respostas coletadas percebe-se uma falta de conhecimento evidente sobre o que é comunicação organizacional e, muitas vezes, esta é identificada apenas como publicidade. A falta de entendimento da importância das divulgações na região da Alta Paulista remete a falta de valor que se dá às próprias ações de responsabilidade socioambiental. As agroindústrias da região analisada ainda não enxergam nessas ações o potencial instrumento de fortalecimento da imagem que pode ser promovido com essas ações e, principalmente, com a eficácia da sua divulgação. PALAVRAS-CHAVE: responsabilidade socioambiental. comunicação organizacional. Imagem organizacional.

O transtorno de compulsão alimentar periódica (TCAP) é um distúrbio psiquiátrico com alta morbidade, associado à obesidade e ao alto risco cardiovascular. O objetivo deste trabalho foi identificar alterações antropométricas e/ou metabólicas em obesos com TCAP e compará-las aqueles sem TCAP. Estudo transversal realizado no ambulatório do Napta/UERJ, envolvendo 39 adultos obesos, sem doenças malignas ou consumptivas e medicamentos que interferissem nos resultados, sendo 22 com e 17 sem TCAP. As variáveis coletadas foram peso, estatura, perímetro da cintura, pressão arterial; e analisadas glicemia, perfil lipídico, dosagem de leptina, adiponectina e insulina, sendo calculado Índice HOMA IR. Os dados foram expressos como média (desvio-padrão), sendo utilizados os testes: Qui-quadrado e t-Student. O valor de significância foi 5%. Amostra composta por 82% de mulheres, com elevada prevalência de hipertensão arterial, resistência insulínica e sedentarismo, sem diferenças entre os grupos com ou sem TCAP. Todos apresentaram o perímetro da cintura acima da recomendação, mais de 60% apresentaram HDL-colesterol baixo e um terço, triglicerídeos elevados. Não houve diferença dos níveis de adiponectina nem de leptina entre obesos com ou sem TCAP, apesar dos valores estarem fora dos limites normais. Obesos independentemente do diagnóstico de TCAP têm elevado risco cardiovascular com alta prevalência de hipertensão arterial, dislipidemia, circunferência de cintura alterada e sedentarismo. Além disso, apresentam inflamação crônica de baixo grau com baixos níveis de adiponectina e altos de leptina. Entretanto, apesar destas afirmativas terem sido confirmadas, não foram identificadas diferenças significativas entre obesos com o transtorno alimentar.
