Dual loop(Roux en Y) reconstruction with isolated gastric limb reduces delayed gastric emptying after pancreatico-duodenectomy

World Journal of Gastrointestinal Surgery 2019年第2期11卷 93-100页

作者： Offir Ben-Ishay reem Abu Zhaya Yoram Kluger Surgical Oncology Unit Division of General Surgery Rambam Health Care Campus

BACKGROUND Single loop reconstruction(SLR) was routine in our institution for patients undergoing pancreatico-duodenectomy(PD). Roux-en Y reconstruction with an isolated gastric limb(RIGL) recently became the reconstruction of *** To evaluate the impact of RIGL on incidence and severity of delayed gastric emptying(DGE).METHODS This is a single institution, retrospective analysis of patients undergoing PD. All patients undergoing PD from July 2010 through December 2016 were included in the study. Outcome of RIGL were compared to SLR. Primary measure of outcome included incidence and severity of DGE. Secondary measures of outcome were overall complications and postoperative *** One hundred and seventy-nine patients were included in the study. Fifty-two had RIGL, 127 had SLR. Overall complication rate was 40.2%, patients in the RIGL group experienced lower rates of DGE(15.4% vs 59.1%, P = 0.001). Other patient related outcomes were also significantly reduced: day of nasogastric tube removal(3 vs 5, P < 0.001), regain of normal diet(8 vs 9, P < 0.001). On multivariate analysis RIGL was associated independently with reduced rates of DGE(P < 0.001, OR 0.14)CONCLUSION The current study shows that RIGL reduces the rate of DGE after PD. Further prospective randomized controlled trials are required to affirm the current data.

Influence of nitrogen sources on growth and mycotoxin production by isolates of Pyrenophora tritici-repentis from wheat

The Crop Journal 2016年第2期4卷 119-128页

The fungus Pyrenophora tritici-repentis(Died.) Drechs. infects the leaves and kernels of wheat,causing tan spot and red smudge, respectively. Isolates of P. tritici-repentis have been reported to be both phytopathogenic and mycotoxigenic. This research investigates the influence of nitrogen sources on growth and production of mycotoxins by eight different isolates of P. tritici-repentis. A synthetic agar medium(SAM) was used with different nitrogen sources, both inorganic [(NH4Cl, NH4NO3and(NH4)2SO4)] and organic(L-alanine, L-histidine, and L-lysine), at a concentration of 37.5 mmol L-1. Individual isolates exhibited different growth rates that varied according to the nitrogen source added to the medium. The choice of nitrogen source also had a major effect on production of the mycotoxins emodin, catenarin and islandicin. The highest concentrations of emodin, 54.40 ± 4.46 μg g-1, 43.07 ± 23.39 μg g-1and28.91 ± 4.64 μg g-1of growth medium, were produced on the complex medium(V8-potato dextrose agar) by the isolates Alg-H2, 331-2 and TS93-71 B, respectively. A relatively high concentration of emodin also was produced by isolates Az35-5(28.29 ± 4.71 μg g-1of medium)and TS93-71B(27.03 ± 4.09 μg g-1of medium) on synthetic medium supplemented with L-alanine. The highest concentrations of catenarin(174.54 ± 14.46 μg g-1and 104.87 ±6.13 μg g-1of medium) were recorded for isolates TS93-71 B and Alg-H2 on synthetic medium supplemented with L-alanine and NH4 Cl, respectively. The highest concentration of islandicin(4.64 ± 0.36 μg g-1medium) was observed for isolate 331-2 in the presence of L-lysine. There was not a close relationship between mycelial growth and mycotoxin production by the fungal isolates. This is the first report on the influence of nitrogen sources on the production of mycotoxins by P. tritici-repentis.

当今工作环境所面临的挑战之一是增强企业创新力,从而提高员工的创造力。领导行为对创造力的产生有重大影响。赋权领导行为是一种未被意识到的重要领导类型之一。为此,本研究将结合领导行为、赋权和创造力的理论,深入研究这种类型的领导力。关于领导力的研究通常涉及一位对团队或员工群体拥有管理权的特定领导者。赋权领导行为是对领导力的一种逐渐发展的感知,认为这是一种集团层面的现象。它建立在诸如自我领导、半自主性和自我管理的工作团体以及参与性决策等能力上,这些能力通常被特定领导者视为领导力的差异。赋权领导行为是通过一些行为实现的,在本研究中,根据先前的一些研究,将讨论八种行为,这些行为代表了领导能力。与其他领导行为相比,赋权领导行为被认为更广泛、更通俗且更易发展。现代研究表明,赋权领导行为可以对各种结果变量产生积极影响。其中就包括创造力。为此,许多关于创造力的研究都表明,赋权领导行为比控制领导行为更容易产生重要影响。增强创造力可能是赋权领导行为权力的最宝贵优势之一。本研究测试了一个理论模型,该模型通过许多主要变量将赋权领导行为与员工的创造力联系起来。其中包括调解人的内在动机和人际信任。该研究的数据是通过一项调查收集的,该调查已分发给在也门的公共和私人电信公司的工作人员、及具有研发项目经验的专业员工。作者发现,正如预料的那样,赋权领导行为会积极影响内在动机,从而反过来会积极影响员工的创造力。此外,人们认识到,基于情感的信任和基于认知的信任调节了赋权领导行为与内在动机之间的关系。这项研究提出了最关键的概念,并证明了一些假设,这些假设为赋权领导行为对员工创造力的影响扫清了道路。解释了未来研究对赋权领导行为和创造力的影响。因此,领导者可以对如何为研发项目中的团队成员创造良好的环境、以增强创造力有清晰的愿景。当领导者注意自己的行为并了解其对员工的影响时,就可以实现这一目标。总而言之,这项研究提供了将赋权领导行为与员工创造力直接联系起来的解释和建议,并提出了对当前管理系统的改进建议。
