    兽医领域需要更多的种族多样性来反映宠物主人和普通人群。当我们检查兽医实践所有权和其他企业家努力的多样性时,问题变得更加复杂。对于少数族裔兽医来说,实现企业所有权的道路充满挑战,他们必须更加努力地向历史上白人职业的怀疑客户证明自己。但是,当不同的兽医采用正确的心态时,他们可以成功成为企业家,与志同道合和支持的同龄人围绕在一起,发展韧性,接受失败,并在需要时学会转向以纠正他们的路线。
    The veterinary field needs more racial diversity to reflect pet owners and the general population. The problem is compounded when we examine diversity in veterinary practice ownership and other entrepreneurial endeavors. The road to business ownership is challenging for minority veterinarians, who must work harder to prove themselves to skeptical clients in a historically white profession. But, diverse veterinarians can succeed as entrepreneurs when they adopt the right mindset, surround themselves with like-minded and supportive peers, develop resilience, accept failure, and learn to pivot when needed to correct their course.

    在现代手球中,重要的性能指标之一是攻击的有效性,尤其是边锋作为线球员的磨合,这还没有得到充分的探索。这项研究的目的是分析边锋在有组织的攻击中奔跑时的运动。从2022年EHF欧洲男子手球锦标赛中分析了58场比赛。总共记录了491次攻击,并分析了45个变量,其中边锋作为第二支点奔跑,结果是投掷。对于统计分析,采用描述性和归纳性统计.结果表明,磨合的平均时间为12.11±9.28s,左翼奔跑的频率更高(60.1%),而边锋倾向于移出防御编队(72.5%)。边锋在没有控球的情况下奔跑(81.1%),移向防守者2和5,站在防守者旁边,偶尔会被阻塞,滑动或离开他们的位置。防守者的中央区域受到球员的青睐。对应分析表明,无论攻击的演变如何,边锋最终都回到了初始位置。他们的作用是阻止特定的防御者或破坏防御,隔离一名防守者,以便一名进攻球员可以从中央区域执行射门。最后,边锋扮演重要角色,尤其是在磨合行动中,在攻击完成时,在最后的投掷中。
    In modern handball, one of the important performance indicators is the effectiveness of the attack, especially the running-in of wingers as line players which has not been explored adequately. The purpose of the study was to analyze the movements of wingers in the organized attack when they run in. Fifty-eight matches were analyzed from the 2022 EHF European Men\'s Handball Championship. A total of 491 attacks were recorded and 45 variables were analyzed in which wingers ran in as second pivots and the outcome was a throw. For the statistical analysis, descriptive and inductive statistics were used. The results showed that the average time of the running-in was 12.11 ± 9.28 s, the left wing ran in more often (60.1%) and wingers tended to move outside the defense formation (72.5%). Wingers ran in without the ball in possession (81.1%), moved toward defenders 2 and 5 and stood next to defenders, and occasionally blocked, slid or left their position. The defense\'s central zone was preferred by players to make a throw. Correspondence analysis showed that wingers finally returned to their initial position regardless of the evolution of the attack. Their role was to block a specific defender or disorganize the defense, for one defender to be isolated so that one attacking player could execute a shot from the central area. Conclusively, wingers play an important role, especially in run-in actions, at the completion of an attack, and in the final throw.

    医学和科学领域的女性经常考虑职业重心向外过渡或向上过渡;在这篇评论中,我们提供了4个经验教训,使这些枢轴最大限度地成功。这些教训强调了必须尊重现在是时候转向的感觉,特别是如果你产生强烈的不安感,表明你在一个不再为你服务的空间;他们还强调寻求导师指导的重要性,赞助商,或教练。尽管灵活性是过渡的重要组成部分,重要的是要以职业发展计划的形式制定路线图,最重要的是专业地完成过渡。
    Women in the fields of medicine and science often consider career pivots to transition out or transition up; in this review, we offer 4 lessons learned to make those pivots maximally successful. These lessons emphasize the need to honor the feeling that it is time to pivot, especially if you develop a strong sense of restlessness indicating you are in a space that no longer serves you; they also emphasize the importance of seeking the guidance of a mentor, sponsor, or coach. Although flexibility is a substantial part of the transition, it is important to have a road map in the form of a career development plan, and it is of utmost importance to complete the transition professionally.

    长期研究项目并不总是能够适应新的危机,并结合快速研究的特点和方法来快速产生有用的数据。项目AViD是一项2018年至2022年之间的研究计划,旨在研究影响疫苗信心的因素。该项目最初侧重于五个国家案例研究,研究埃博拉疫苗,麻疹,裂谷热和寨卡。COVID-19大流行是在这段时间出现的,并为大流行的“百万美元问题”--如何部署COVID-19疫苗提供了一个机会。借鉴我们作为研究人员的经验,特别是从AVID,我们提出了七个因素,这些因素可以影响长期定性研究项目何时以及如何适应并有助于应对不断发展的卫生紧急情况。其中包括:(1)紧急情况发生的研究阶段;(2)紧急情况在研究环境中的相对重要性;(3)具体方法和研究团队能力;(4)现有的业务联系;(5)支持性生态系统;(6)研究合同和资金的灵活性;(7)研究团队的态度和方法。我们最后考虑了两个长期研究项目,这些项目发现自己在公共卫生紧急情况下不得不“改变装备”——需要重新评估风险和收益,以及需要保护公平的伙伴关系。
    Long-term research projects are not always able to adapt to a new crisis and incorporate characteristics and approaches of rapid research to produce useful data quickly. Project AViD was a programme of research that ran between 2018 and 2022 to examine factors that shape vaccine confidence. The project initially focused on five country case studies looking at vaccines for Ebola, Measles, Rift Valley Fever and Zika. The COVID-19 pandemic emerged during this time and provided an opportunity to contribute to the pandemic\'s \'million-dollar question\'-how to deploy COVID-19 vaccines. Drawing on our experience as researchers, and specifically from AViD, we propose seven factors that can influence when and how longer-term qualitative research projects can adapt and contribute to the response to an unfolding health emergency. These include: (1) the phase of research in which the emergency hits; (2) the relative significance of the emergency in the research setting; (3) the specific methods and research team capacities; (4) existing operational links; (5) supportive ecosystems; (6) flexibility in research contracting and funding; and (7) the research team attitude and approach. We close with two considerations for longer-term research projects that find themselves having to \"change gear\" amid a public health emergency-the need to re-assess risks and benefits and the need to protect equitable partnerships.

    对骨形态与体内胫骨-股骨运动学之间关系的更好理解可能会增强膝关节疾病患者的功能预后。这项研究的目的是量化健康受试者在整个步态周期中股骨和胫骨骨形态对胫骨-股骨运动学的影响。26名志愿者接受了临床检查,射线照相评估,水平行走时的动态视频透视,下坡行走,和楼梯下降。股骨计算机断层扫描(CT)测量包括内侧髁(MC)和外侧髁(LC)宽度,MC和LC屈曲圆,股骨外侧髁指数(LFCI)。胫骨CT测量包括内侧(MTP)和外侧胫骨平台(LTP)斜率,深度,长度,和宽度。在多元回归模型中分析了骨形态对胫骨内部/外部旋转以及外侧和内侧隔室的前后(AP)平移的影响。在水平行走的加载姿势阶段,随着MC宽度β:-0.30(95%CI:-0.58至-0.03)(p=0.03)的减小,可以证明胫骨内部/外部旋转的增加。在水平行走的负重站立阶段,LC屈曲圆β:-0.16(95%CI:-0.28至-0.05)较小(p=0.007)和MTPβ:0.90(95%CI:0.23至1.56)(p=0.01)均增加了横向AP平移。确定的体内胫骨-股骨运动学和骨形态学之间的关系支持膝关节疾病患者对这些因素的定制方法和个人评估,并可能增强前交叉韧带损伤和全膝关节置换术的功能结果。
    An improved understanding of the relationships between bone morphology and in vivo tibio-femoral kinematics potentially enhances functional outcomes in patients with knee disorders. The aim of this study was to quantify the influence of femoral and tibial bony morphology on tibio-femoral kinematics throughout complete gait cycles in healthy subjects. Twenty-six volunteers underwent clinical examination, radiographic assessment, and dynamic video-fluoroscopy during level walking, downhill walking, and stair descent. Femoral computer-tomography (CT) measurements included medial condylar (MC) and lateral condylar (LC) width, MC and LC flexion circle, and lateral femoral condyle index (LFCI). Tibial CT measurements included both medial (MTP) and lateral tibial plateau (LTP) slopes, depths, lengths, and widths. The influence of bony morphology on tibial internal/external rotation and anteroposterior (AP)-translation of the lateral and medial compartments were analyzed in a multiple regression model. An increase in tibial internal/external rotation could be demonstrated with decreasing MC width β: -0.30 (95% CI: -0.58 to -0.03) (p = 0.03) during the loaded stance phase of level walking. An increased lateral AP-translation occurred with both a smaller LC flexion circle β: -0.16 (95% CI: -0.28 to -0.05) (p = 0.007) and a deeper MTP β: 0.90 (95% CI: 0.23 to 1.56) (p = 0.01) during the loaded stance phase of level walking. The identified relationship between in vivo tibio-femoral kinematics and bone morphology supports a customized approach and individual assessment of these factors in patients with knee disorders and potentially enhances functional outcomes in anterior cruciate ligament injuries and total knee arthroplasty.

    文章类型: English Abstract
    BACKGROUND: The anterior cruciate ligament is an anatomical structure that tends to cause problems for specialists when formulating an accurate diagnosis. There are measurement tools that support the diagnosis such as the KT1000; however, it still has some limitations, since it only manages to measure a single axis of movement, while the \"pivot-shift\" maneuver manages to capture more information about the state of the ligament, as it allows to evaluate the three axes of movement of the joint. The \"pivot-shift\" maneuver lacks a standard execution, therefore it can produce disagreement between evaluators; this creates the need for a tool capable of standardizing the maneuver, while providing an interpretable measurement.
    METHODS: Pivot-shift meter application, a mobile software capable of capturing information on the movements made when executing a pivot maneuver. Intraclass correlation coefficient to measure the intra- and inter-observer correlation of the information captured by the application. The data was obtained from 66 random participants, using the mobile phone\'s built-in gyroscopes.
    RESULTS: With the 66 tests carried out, it was observed that the evaluators tend to achieve high reproducibility when executing the maneuvers within the time period established by the application, which reached an intraclass correlation coefficient above 90%.
    CONCLUSIONS: The intra- and inter-observer correlation is high enough to be able to perform a quantitative analysis of the pivot-shift maneuver, through a mobile phone.
    UNASSIGNED: El ligamento cruzado anterior es una estructura anatómica que tiende a dar problemas a los especialistas al formular un diagnóstico certero. Existen herramientas de medición que apoyan el diagnóstico como el KT1000; sin embargo, aún presenta algunas limitaciones, pues sólo logra medir un solo eje de movimiento, mientras que la maniobra de pivot-shift logra capturar más información sobre el estado del ligamento, ya que permite evaluar los tres ejes de movimiento de la articulación. La maniobra de pivot-shift carece de una ejecución estándar, por ello puede producir discordancia entre evaluadores; así se crea la necesidad de una herramienta capaz de estandarizar la maniobra al tiempo que arroje una medición interpretable.
    UNASSIGNED: La aplicación \"pivot-shift meter\" es un software para móviles capaz de capturar información de los movimientos realizados al ejecutar una maniobra de pivote. Se utilizó el índice de correlación intraclase para medir la correlación intra- e interobservador de la información capturada por la aplicación. Los datos fueron obtenidos de 66 participantes aleatorios, mediante el giroscopio integrado del teléfono móvil.
    RESULTS: Con los 66 ensayos realizados se observó que los evaluadores tienden a alcanzar una alta reproducibilidad al ejecutar las maniobras dentro del periodo de tiempo establecido por la aplicación, que alcanzó un índice de correlación intraclase por encima de 90%.
    UNASSIGNED: La correlación intra- e interobservador es lo suficientemente alta como para poder realizar un análisis cuantitativo de la maniobra de pivot-shift a través de un teléfono móvil.

    肿瘤发生的进展始于细胞中的一些突变和结构驱动事件。存在各种基于群组的计算工具来鉴定驱动基因,但是需要多个样品来鉴定不那么频繁地突变的驱动基因。许多研究使用不同的方法从突变中识别驱动突变/基因,这些突变对肿瘤进展没有影响;然而,一小部分患者在任何已知的驱动基因中均未出现突变事件.当前的无监督方法将体细胞和表达数据映射到网络上,以基于表达变化识别个性化的驱动基因。我们的方法是第一个将基因分类为肿瘤抑制基因(TSG)的机器学习模型,癌基因(OG),或中性,从而确定基因对患者的功能影响。在这项研究中,我们开发了一种多才多艺的方法,PIVOT(驾驶员OGs和TSG的个性化标识),训练实验或计算验证的突变和结构驱动事件。鉴于缺乏识别个性化驾驶员基因的黄金标准,我们使用四种策略标记数据,基于分类度量,显示基于基因的标记策略表现最佳。我们使用SNV建立不同的模型,RNA,以及根据可用数据使用的多维特征。与突变和表达数据相比,我们在多维数据上训练的模型改善了预测,达到BRCA的精度≥0.99,LUAD,和COAD数据集。我们展示了基于网络和表情的功能对PIVOT的贡献最大。我们对BRCA的预测,COAD,和LUAD癌症类型揭示了常见的改变基因,如TP53和PIK3CA,预测多种癌症类型的驱动因素。连同已知的驱动基因,我们的模型还确定了新的驱动基因,如PRKCA,SOX9和PSMD4。我们的多组模型标记CNV和突变,CNV改变的贡献更大。在预测多个样本中突变基因的标记时,我们还标记罕见的驱动事件发生在一个样本。我们还确定了在同一癌症类型中具有双重作用的基因。总的来说,PIVOT将个性化的驱动基因标记为TSG和OGs,还鉴定了罕见的驱动基因。
    The progression of tumorigenesis starts with a few mutational and structural driver events in the cell. Various cohort-based computational tools exist to identify driver genes but require multiple samples to identify less frequently mutated driver genes. Many studies use different methods to identify driver mutations/genes from mutations that have no impact on tumor progression; however, a small fraction of patients show no mutational events in any known driver genes. Current unsupervised methods map somatic and expression data onto a network to identify personalized driver genes based on changes in expression. Our method is the first machine learning model to classify genes as tumor suppressor gene (TSG), oncogene (OG), or neutral, thus assigning the functional impact of the gene in the patient. In this study, we develop a multi-omic approach, PIVOT (Personalized Identification of driVer OGs and TSGs), to train on experimentally or computationally validated mutational and structural driver events. Given the lack of any gold standards for the identification of personalized driver genes, we label the data using four strategies and, based on classification metrics, show gene-based labeling strategies perform best. We build different models using SNV, RNA, and multi-omic features to be used based on the data available. Our models trained on multi-omic data improved predictions compared with mutation and expression data, achieving an accuracy ≥ 0.99 for BRCA, LUAD, and COAD datasets. We show network and expression-based features contribute the most to PIVOT. Our predictions on BRCA, COAD, and LUAD cancer types reveal commonly altered genes such as TP53 and PIK3CA, which are predicted drivers for multiple cancer types. Along with known driver genes, our models also identify new driver genes such as PRKCA, SOX9, and PSMD4. Our multi-omic model labels both CNV and mutations with a more considerable contribution by CNV alterations. While predicting labels for genes mutated in multiple samples, we also label rare driver events occurring in as few as one sample. We also identify genes with dual roles within the same cancer type. Overall, PIVOT labels personalized driver genes as TSGs and OGs and also identified rare driver genes.

    背景:前交叉韧带(ACL)损伤的体格检查极为重要,和杠杆测试通常用于ACL评估。然而,杠杆测试的研究数量和范围是有限的。在这项前瞻性横断面研究中,我们的目的是评估拉赫曼诊断价值的有效性,枢轴位移,杠杆,和前抽屉测试方面的股四头肌萎缩和ACL损伤的病例阶段。
    方法:在这项前瞻性研究中,Lachman的诊断价值,枢轴位移,杠杆,对189例MRI结果阳性的患者进行了前抽屉测试。
    结果:治疗前后股四头肌萎缩组的杠杆试验阳性发生率明显更高(p<0.05)。前抽屉试验阳性在术前股四头肌萎缩阳性组中明显更频繁,镇静后和脊髓麻醉后(p<0.05)。杠杆和前抽屉试验与镇静前和镇静后股四头肌萎缩呈正相关(p<0.05)。手术前的杠杆测试,镇静和脊髓麻醉后,慢性患者组的阳性高于急性和亚急性组(p<0.05)。杠杆试验与术前阶段呈正相关,镇静后和脊髓麻醉后(p<0.01)。
    结论:急性,亚急性,或慢性ACL损伤对杠杆试验的预测价值有显著影响。我们认为单变量分析在证明预测值时可能会给出错误的结果,进行多变量分析会更正确。
    BACKGROUND: The physical examination in anterior cruciate ligament (ACL) injuries is extremely important, and the Lever test is commonly utilized on ACL evaluation. However, the number and scope of studies on the Lever test is limited. In this prospective cross-sectional study, we aimed to evaluate the effectiveness of the diagnostic values of Lachman, Pivot Shift, Lever, and Anterior Drawer tests in terms of quadriceps atrophy and case phase in ACL injuries.
    METHODS: In this prospective study, diagnostic values of Lachman, Pivot Shift, Lever, and Anterior Drawer tests were examined on 189 patients with positive MRI results as the gold standard.
    RESULTS: Lever test positivity was significantly more frequent in the group with quadriceps atrophy preoperative and after sedation (p<0.05). Anterior Drawer test positivity was significantly more frequent in the group with positive quadriceps atrophy preoperatively, after sedation and after spinal anesthesia (p<0.05). Lever and Anterior Drawer tests were positively correlated with quadriceps atrophy preop and after sedation (p<0.05). Lever test before surgery, after sedation and after spinal anesthesia in the chronic patient group was more positive than in the acute and subacute groups (p<0.05). Lever test was positively correlated with phase preoperatively, after sedation and after spinal anesthesia (p<0.01).
    CONCLUSIONS: The presence or absence of quadriceps atrophy in patients with acute, sub-acute, or chronic ACL injury has a significant effect on the predictive value of the Lever test. We think that univariate analyzes may give incorrect results when demonstrating predictive value, and it would be more correct to perform multivariate analyzes.
