Fluxo de proteína do Rúmen para o duodeno de novilhos alimentados com dieta volumosa e dieta concentrada

Four cannulated steers were used to compare the effect of diet ( concentrate vs. roughage ) on the duodenal N and aminoacidos (AA) flow. Lignin and Cr2O3 were compared with automated total collection (ATC) for estimated duodenal N flow over 3 to 6 – day collection periods. Estimations based on Cr2O3 and lignin were about 10 to 15% great (P < 0.05 ) than direct flow measurements by ATC. Daily duodenal N flow was about 30 % great than daily N intake in the concentrate diet. Intake and duodenal flow of N were similar in the roughage diet. Duodenal AA flow values expressed as percentage of intake were greater in the concentrate diet than in roughage (P < 0.01), especially DAP, suggesting more bacterial synthesis in the concentrate diet. There was a net gain in AA due to a ruminal digestion in the concentrate diet. LYS, THR and ILE were the three EAA that increased the most in the concentrate diet and the only ones that increased in the roughage diet. The date suggest a beneficial effect on the duodenal N and EAA flow by increasing dietary nonstructural carbohydrate. Further studies are necessary to establish the value of the structural and non-out-flow reaching the duodenum.Quatro novilhos fistulados foram usados para comparar o efeito da dieta (volumoso vs. concentrado) no fluxo duodenal de N e aminoácidos (AA). Lignina e Cr2O3 foram comparados com a coleta total automática (ATC), para estimar o fluxo duodenal de N em períodos de três a seis dias de coleta. As estimativas do fluxo de N baseadas no Cr2O3 e lignina foram, em média, 10 a 15% maiores (P < 0,05) do que aquela baseada na ATC. O fluxo duodenal diário de N na dieta concentrada foi cerca de 30% maior do que o ingerido. Essa diferença entre a ingestão e o fluxo duodenal de N não ocorreu de modo significativo na dieta volumosa. O fluxo duodenal de AA, em valores expressos como percentagem da quantidade ingerida, foi maior na dieta concentrada do que na dieta volumosa (P < 0,01), especialmente DAP, sugerindo maior síntese bacteriana na dieta concentrada. Ocorreu um ganho líquido em AA devido à digestão ruminal na dieta concentrada. Entre os AA essenciais (AAE), o maior ganho ocorreu com LYS, THR e ILE, na dieta concentrada, e foram estes os únicos AAE que apresentaram ganho líquido na dieta volumosa. Os dados sugerem um maior fluxo duodenal de N e AAE com o aumento de carboidrato não estrutural na dieta. Outros estudos são necessários para o estabelecimento da proporção ideal entre  carboidrato não estrutural versus proteína na dieta, visando a otimização do fluxo duodenal de aminoácidos

The impact of seasonal operating room closures on wait times for oral cancer surgery

Background Operating room slowdowns occur at specific intervals in the year as a cost-saving measure. We aim to investigate the impact of these slowdowns on the care of oral cavity cancer patients at a Canadian tertiary care centre. Methods A total of 585 oral cavity cancer patients seen between 1999 and 2015 at the London Health Science Centre (lhsc) Head and Neck Multidisciplinary Clinic were included in this study. Operating room hours and patient load from 2006 to 2014 were calculated. Our primary endpoint was the wait time from consultation to definitive surgery. Exposure variables were defined according to wait time intervals occurring during time periods with reduced operating room hours. Results Overall case volume rose significantly from 2006 to 2014 (p \u3c 0.001), while operating room hours remained stable (p = 0.555). Patient wait times for surgery increased from 16.3 days prior to 2003 to 25.5 days in 2015 (p = 0.008). Significant variability in operating room hours was observed by month, with lowest reported for July and August (p = 0.002). The greater the exposure to these months, the more likely patients were to wait longer than 28 days for surgery (odds ratio per day [or]: 1.07, 95% confidence interval [ci]: 1.05 to 1.10, p \u3c 0.001). Individuals seen in consultation preceding a month with below average operating room hours had a higher risk of disease recurrence and/or death (hazard ratio [hr]: 1.59, 95% ci: 1.10 to 2.30, p = 0.014). Conclusions Scheduled reductions in available operating room hours contribute to prolonged wait times and higher disease recurrence. Further work is needed to identify strategies maximizing efficient use of health care resources without negatively affecting patient outcomes

The effect on foreign multinationals: an under-explored aspect of Brexit

While most of the studies on Brexit have focused on its trade effects, very few have analysed the likely impact on foreign multinationals. Claudia Fernández-Pacheco Theurer (Universidad Autonoma de Madrid), Jose Luis López Ruiz and María C. Latorre (Universidad Complutense de Madrid, left) argue that this is an important omission. They show how data on trade and foreign multinationals affiliates' sales underlines the different relationship between the UK and EU-27 on both fronts. They go on to explain the EU trade and investment regulatory regimes and analyse a few studies of Brexit, including its effect on multinationals
