    目标:优化物理治疗师教育中的学习,学习者需要从他们独特的起点成长的机会。传统的分级做法,如A到F级,零级,对及时性和专业性的评分阻碍了内容的掌握和准确的能力评估。分级应注重技能和内容的掌握,使用最终成绩的总结性评估,无零政策,和可操作的反馈。公平评分支持来自所有背景和身份的学习者,并促进学术成功。本案例研究为在学术物理治疗计划中实施公平的评分实践提供了指导和建议。
    方法:在2年内,DPT计划开始实施5种策略,以创建更公平的评分实践:(1)消除零成绩,(2)允许延迟提交转让而不受到惩罚,(3)在整个学期中使用低风险形成性评估,(4)对课程结束评估的权重高于初始评估,和(5)在入学前提供无桩解剖预备课程。
    结果:实施公平评分做法的结果各不相同。一些学习者感到分数机会减少带来的压力增加,而其他人则赞赏低风险评估减少的焦虑。有些人认为对同龄人的多次尝试是不公平的。由于详细的反馈和补救,教师面临着更高的工作量,但认为这有利于学习者。一些课程的期末成绩中位数有所提高,在其他方面保持稳定,并略有下降。总的来说,这些变化对大多数学习者的成绩影响不大,但对陷入困境的学习者来说,结果和保留率显着改善。
    结论:本案例报告记录了在DPT计划中实施公平评分做法的情况,为其他旨在采用类似做法的机构提供有价值的见解和建议。
    结论:评估中的不平等扩大了学习者进入专业课程之间的差距。公平评估做法公平竞争,使来自不同背景和身份的学习者能够成功。增加多样性使每个人受益,尤其是病人,通过减少历史边缘化群体的健康差距。
    OBJECTIVE: To optimize learning in physical therapist education, learners need opportunities to grow from their unique starting points. Traditional grading practices like A to F grades, zero grades, and grading on timeliness and professionalism hinder content mastery and accurate competency assessment. Grading should focus on mastery of skill and content, using summative assessments for final grades, a no-zero policy, and actionable feedback. Equitable grading supports learners from all backgrounds and identities and promotes academic success. This case study provides guidance and recommendations for implementing equitable grading practices in academic physical therapy programs.
    METHODS: Over a 2-year period, a DPT program began implementing 5 strategies to create more equitable grading practices: (1) eliminating zero grades, (2) allowing late assignment submissions without penalty, (3) using low-stakes formative assessments throughout the semester, (4) weighing end-of-course assessments more heavily than initial ones, and (5) offering a no-stakes anatomy prep course before matriculation.
    RESULTS: Outcomes from implementing equitable grading practices varied. Some learners felt increased stress from fewer points opportunities, while others appreciated the reduced anxiety from low-stakes assessments. Some saw multiple attempts for peers as unfair.Faculty faced higher workloads due to detailed feedback and remediation but believed it benefited learners. Median final grades improved in some courses, remained stable in others, and slightly decreased in one. Overall, the changes had minimal impact on most learners\' grades but significantly improved outcomes and retention for struggling learners.
    CONCLUSIONS: This case report documents the implementation of equitable grading practices in a DPT program, offering valuable insights and recommendations for other institutions aiming to adopt similar practices.
    CONCLUSIONS: Inequity in assessment widens the gap between learners entering professional programs. Equitable assessment practices level the playing field, enabling learners from diverse backgrounds and identities to succeed. Increased diversity benefits everyone, especially patients, by reducing health disparities for historically marginalized groups.

    没有关于健康的社会决定因素(SDoH)如何影响患者护理和健康结果的明确教育和培训,医学院未能有效地装备未来的医生为患者服务。我们创建了这个关于健康公平的研讨会,重点是SDoH,以帮助学生更有效地与不同人群沟通。
    为三年级医学生和教职员工提供了课程指南,学习目标,角色扮演小插曲,其中包含特定于职员的历史和身体检查,时间表,在以SDoH为中心的2小时会议中讨论问题。研讨会的影响是通过调查的混合方法分析来衡量的。
    根据87名参与者的调查前后结果,医学生强烈同意(1)与临床接触相比,SDoH对患者健康结果的影响更大(pre:67%,职位:87%),(2)收集有关SDoH的信息是他们的责任(pre:86%,职位:97%),(3)邻域安全是SDoH的关键之一(pre:88%,职位:97%),(4)他们了解上游干预措施的影响(pre:35%,职位:93%),(5)他们可以在每次医疗时有效地筛查所有患者的SDoH(pre:27%,职位:86%),和(6)他们可以找到初步资源,以快速帮助需要帮助的患者关于特定的SDoH(pre:26%,职位:85%)。
    这是本次研讨会的第一次迭代;挑战涉及内容的试点,时间限制,车间的组织结构设计。未来的方向包括使SDoH课程成为本科医学教育和多样化临床环境的组成部分。
    UNASSIGNED: Without explicit education and training on how social determinants of health (SDoH) impact patient care and health outcomes, medical schools are failing to effectively equip future physicians to serve their patients. We created this workshop on health equity with a focus on SDoH to help students more effectively communicate with diverse populations.
    UNASSIGNED: Third-year medical students and faculty were provided with class guides, learning objectives, role-play vignettes containing clerkship-specific history and physical exams, schedules, and discussion questions during a 2-hour session centered on SDoH. The workshop\'s impact was measured through mixed-methods analysis of surveys.
    UNASSIGNED: Based on pre- and postsurvey results from 87 participants, medical students strongly agreed that (1) SDoH factor more into a patient\'s health outcomes than the clinical encounter (pre: 67%, post: 87%), (2) it is their duty to gather information about SDoH (pre: 86%, post: 97%), (3) neighborhood safety is one of the key SDoH (pre: 88%, post: 97%), (4) they understood the impact of upstream interventions (pre: 35%, post: 93%), (5) they could efficiently screen all patients for SDoH at every medical encounter (pre: 27%, post: 86%), and (6) they could find preliminary resources to quickly assist patients in need of help regarding particular SDoH (pre: 26%, post: 85%).
    UNASSIGNED: This was the first iteration of this workshop; challenges involved piloting the content, time restraints, and organizational structure of the workshop design. Future directions include making SDoH curricula an integral part of undergraduate medical education and diverse clinical environments.

    医学课程隐含地教导种族具有生物学基础。临床轮换强化了这种误解,因为基于种族的算法用于指导临床决策。本模块旨在揭露临床算法中种族的谬误,以估计的肾小球滤过率(eGFR)方程为例。
    我们在与肾脏病学家协商后创建了一个60分钟的模块。格式是互动的,基于案例的演示,带有说教部分。一名三年级的医学生为医学生提供了便利。评估包括使用5点Likert量表进行的前/后调查,以评估有关将种族用作生物学结构的认识。更高的分数表明意识增强。
    55名学生参加了该模块。前/后结果表明,学生对医学界种族主义历史的自我感知知识显着提高(2.6vs.3.2,p<.001),临床算法中的种族意识(2.7vs.3.7,p<.001),基于种族的eGFR对生活质量/治疗结果的影响(4.5vs.4.8,p=0.01),种族和祖先之间的差异(3.7vs.4.3,p<.001),以及不从eGFR方程中删除种族的含义(2.7与4.2,p<.001)。学生对研讨会的质量和清晰度给予高度评价。
    我们的模块扩展了其他\'工作,以揭露基于种族的算法的谬误,并定义其对健康公平的影响。局限性包括缺乏对知识获取的客观评估。我们建议将此模块整合到临床前和临床课程中,以讨论种族在医学文献和临床实践中的使用。
    UNASSIGNED: Medical curricula implicitly teach that race has a biological basis. Clinical rotations reinforce this misconception as race-based algorithms are used to guide clinical decision-making. This module aims to expose the fallacy of race in clinical algorithms, using the estimated glomerular filtration rate (eGFR) equation as an example.
    UNASSIGNED: We created a 60-minute module in consultation with nephrologists. The format was an interactive, case-based presentation with a didactic section. A third-year medical student facilitated the workshops to medical students. Evaluation included pre/post surveys using 5-point Likert scales to assess awareness regarding use of race as a biological construct. Higher scores indicated increased awareness.
    UNASSIGNED: Fifty-five students participated in the module. Pre/post results indicated that students significantly improved in self-perceived knowledge of the history of racism in medicine (2.6 vs. 3.2, p < .001), awareness of race in clinical algorithms (2.7 vs. 3.7, p < .001), impact of race-based eGFR on quality of life/treatment outcomes (4.5 vs. 4.8, p = .01), differences between race and ancestry (3.7 vs. 4.3, p < .001), and implications of not removing race from the eGFR equation (2.7 vs. 4.2, p < .001). Students rated the workshops highly for quality and clarity.
    UNASSIGNED: Our module expands on others\' work to expose the fallacy of race-based algorithms and define its impact on health equity. Limitations include a lack of objective assessment of knowledge acquisition. We recommend integrating this module into preclinical and clinical curricula to discuss the use of race in medical literature and clinical practice.

    背景:神经外科表现出明显较低的布莱克代表性,西班牙裔,和女性外科医生相比,其他各种医疗和外科专业。现有的研究集中在医学生对外科医生的看法,影响女医学生对外科领域偏好的因素,以及考虑从事神经外科职业的学生的兴趣和关注点。然而,在理解对神经外科感兴趣的女医学生的独特关注和观点方面存在显著差距。
    方法:从DC地区的医学院招募了对女医学生的半结构化访谈。面试问题基于Lent和Brown的社会认知职业理论。成绩单按主题分析为代码。
    结果:总计,我们机构的8名女医学生参加了。我们确定了影响医学生决策的三个主要主题:归属感(多样性,导师,热情),自我效能感(雄心勃勃/“枪手”,激烈/竞争),和结果预期(创新/研究,直接影响,程序/外科方面,薪水,工作与生活的平衡)。
    结论:女医学生在选择神经外科职业时面临不同的挑战和需要考虑的因素。女学生最关心的是归属感。必须增强神经外科专业的多样性,并提高女性神经外科医师的代表性。旨在解决和减轻其具体关切的早期干预措施对于实现这一目标至关重要。
    BACKGROUND: Neurosurgery exhibits notably lower representation of Black, Hispanic, and female surgeons compared to various other medical and surgical specialties. Existing research focuses on medical students\' views on surgeons, factors influencing female medical students\' preferences in surgical fields, and the perceived interests and concerns of students contemplating a career in neurosurgery. However, there is a significant gap in understanding the unique concerns and perspectives of female medical students interested in neurosurgery.
    METHODS: Semi-structured interviews with female medical students were recruited from medical schools in the DC area. Interview questions were based on Lent and Brown\'s Social Cognitive Career Theory. Transcripts were analyzed thematically into codes.
    RESULTS: In total, 8 female medical students from our institution participated. We identified three major themes that influenced medical students decision making: sense of belonging (diversity, mentorship, passionate), self-efficacy (ambitious/\"gunner\", intense/competitive), and outcome expectations (innovation/research, immediate impact, procedural/surgical aspect, salary, work-life balance).
    CONCLUSIONS: Female medical students face distinct challenges and factors to consider when choosing a career in neurological surgery. The biggest concern for female students was a sense of belonging. It is imperative to enhance the diversity within the neurosurgical specialty and boost the representation of female neurosurgeons. Early interventions designed to tackle and alleviate their specific concerns are pivotal in achieving this goal.

    海洋骨料的开采代表了面对陆地骨料资源枯竭的机会。这项活动的环境影响已经在几项研究中进行了评估,导致制定建议以减轻其影响。这项研究调查了其对环境的影响,低强度提取的高电流环境,一个以前没有广泛研究过的独特场景。采用多变量分析和营养组方法,它考察了物种和群落层面的复杂反应。结果表明生物多样性下降,促进r选择物种的建立,特别是过滤器喂食器。尽管现场恢复时间表仍然不确定,初步迹象表明,该地点迅速恢复(2-3年)。该研究还讨论了对这些低强度疏浚地点进行采样的方法学挑战,并强调需要针对这种压力和强流体动力学下的粗沉积物量身定制的新指标。这些见解为未来的研究提供了有价值的方向。
    Marine aggregate extraction represents an opportunity to face the depletion of terrestrial aggregate resources. The environmental effects of this activity have been assessed in several studies, leading to the formulation of recommendations to mitigate its effects. This study investigates its environmental impacts in a coarse, high-current environment with low-intensity extraction, a unique scenario not extensively studied before. Employing multivariate analyses and a trophic group approach, it examines complex responses at both species and community levels. Results indicate a decline in biodiversity, promoting the establishment of r-selected species, particularly filter feeders. Although site restoration timelines remain uncertain, initial indications suggest rapid recovery (2-3 years) for this site. The study also discusses methodological challenges in sampling these low-intensity dredged sites and emphasizes the need for new indices tailored to this pressure and coarse sediments under strong hydrodynamics. These insights offer valuable directions for future research.

    BACKGROUND: Recruitment of sufficient and diverse participants into clinical research for Alzheimer\'s disease and related dementias remains a formidable challenge. The primary goal of this manuscript is to provide an overview of an approach to diversifying research recruitment and to provide case examples of several methods for achieving greater diversity in clinical research enrollment.
    METHODS: The University of Kansas Alzheimer\'s Disease Research Center (KU ADRC) developed MyAlliance for Brain Health (MyAlliance), a service-oriented recruitment model. MyAlliance comprises a Primary Care Provider Network, a Patient and Family Network, and a Community Organization Network, each delivering tailored value to relevant parties while facilitating research referrals.
    RESULTS: We review three methods for encouraging increased diversity in clinical research participation. Initial outcomes reveal an increase in underrepresented participants from 17% to 27% in a research registry. Enrollments into studies supported by the research registry experienced a 51% increase in proportion of participants from underrepresented communities.
    CONCLUSIONS: MyAlliance shifts power, resources, and knowledge to community advocates, promoting brain health awareness and research participation, and demands substantial financial investment and administrative commitment. MyAlliance offers valuable lessons for building sustainable, community-centered research recruitment infrastructure, emphasizing the importance of localized engagement and cultural understanding.
    UNASSIGNED: MyAlliance led to a significant increase in the representation of underrepresented racial and ethnic groups and individuals from rural areas.The service-oriented approach facilitated long-term community engagement and trust-building, extending partnerships between an academic medical center and community organizations.While effective, MyAlliance required substantial financial investment, with costs including infrastructure development, staff support, partner organization compensation, and promotional activities, underscoring the resource-intensive nature of inclusive research recruitment efforts.

    地方品种是重要的遗传资源,对保持传统农业生态系统的长期可持续性具有重要作用,食物,营养,和生计安全。为了在农场保护背景下记录地方品种,对印度中西部Ghat地区进行了调查。从24个地点记录了属于60种作物的671个地方品种。保管员农民被发现可以保护包括蔬菜在内的各种农作物,谷物和豆类,多年生水果,香料,块茎和种植园作物。调查表明,各个地点的地方品种流行率存在差异。关于香农多样性指数的显著差异,Gini-Simpson指数,均匀度,物种丰富度,在不同的调查地点之间观察到丰富。流行指数的计算表明,需要立即采取干预措施,以收集和异地保护某些作物的地方品种,作为农场保护的后盾。该研究还确定了农场保护的关键决定因素,包括(I)对区域条件的适宜性,(ii)与区域美食和当地医学实践的相关性,(三)文化和传统的意义,(四)经济优势。本研究中记录的信息有望促进地方品种异地的收集和保护。国家基因库位于ICAR-NBPGR,新德里保存了从本报告调查的中西部高止山脉地区收集的约550种地方品种。从托管农民那里收集的有关特定用途的信息将有助于提高这些种质的利用率。
    Landraces are important genetic resources that have a significant role in maintaining the long-term sustainability of traditional agro-ecosystems, food, nutrition, and livelihood security. In an effort to document landraces in the on-farm conservation context, Central Western Ghat region in India was surveyed. A total of 671 landraces belonging to 60 crops were recorded from 24 sites. The custodian farmers were found to conserve a variety of crops including vegetables, cereals and pulses, perennial fruits, spices, tuber and plantation crops. The survey indicated a difference in the prevalence of landraces across the sites. A significant difference with respect to the Shannon-diversity index, Gini-Simpson index, evenness, species richness, and abundance was observed among the different survey sites. Computation of a prevalence index indicated the need for immediate intervention in the form of collecting and ex situ conservation of landraces of some crops as a back-up to on-farm conservation. The study also identified the critical determinants of on-farm conservation, including (i) suitability to regional conditions, (ii) relevance in regional cuisine and local medicinal practices, (iii) cultural and traditional significance, and (iv) economic advantage. The information documented in this study is expected to promote the collection and conservation of landraces ex situ. The National Genebank housed at ICAR-NBPGR, New Delhi conserves around 550 accessions of landraces collected from the Central Western Ghats region surveyed in this report. Information collected from custodian farmers on specific uses will be helpful to enhance the utilization of these accessions.

    Molnupiravir,一种在体外有效对抗SARS-CoV-2的口服直接作用抗病毒药物,已在COVID-19大流行期间大量使用,自2021年12月。经过营销和广泛使用,SARS-CoV-2谱系的逐渐增加,其特征是更高的转变/转变比率,莫努比拉韦行动的特征标志,出现在全球共享所有流感数据倡议(GISAID)和国际核苷酸序列数据库合作(INSDC)数据库中。这里,我们通过SARS-CoV-2全基因组测序评估了38例接受莫诺比拉韦治疗的持续阳性COVID-19门诊患者在治疗前后的药物效果.17名接受tixagevimab/cilgavimab治疗的门诊患者作为对照。突变分析证实,SARS-CoV-2在开始使用molnupiravir后7天表现出更高的转变/转化率。此外,我们观察到与对照组相比,G->A比率增加,与载脂蛋白BmRNA编辑酶无关,催化多肽样(APOBEC)活性。此外,我们首次证明了病毒准种的多样性和复杂性增加.
    Molnupiravir, an oral direct-acting antiviral effective in vitro against SARS-CoV-2, has been largely employed during the COVID-19 pandemic, since December 2021. After marketing and widespread usage, a progressive increase in SARS-CoV-2 lineages characterized by a higher transition/transversion ratio, a characteristic signature of molnupiravir action, appeared in the Global Initiative on Sharing All Influenza Data (GISAID) and International Nucleotide Sequence Database Collaboration (INSDC) databases. Here, we assessed the drug effects by SARS-CoV-2 whole-genome sequencing on 38 molnupiravir-treated persistently positive COVID-19 outpatients tested before and after treatment. Seventeen tixagevimab/cilgavimab-treated outpatients served as controls. Mutational analyses confirmed that SARS-CoV-2 exhibits an increased transition/transversion ratio seven days after initiation of molnupiravir. Moreover we observed an increased G->A ratio compared to controls, which was not related to apolipoprotein B mRNAediting enzyme, catalytic polypeptide-like (APOBEC) activity. In addition, we demonstrated for the first time an increased diversity and complexity of the viral quasispecies.

    由于不断的变化和生物多样性的下降,今天的科学应该依靠长期的基于物种的生态研究。我们对水甲虫科进行了长期的生态动力学研究,which,尽管它在底栖群落中非常丰富,仍然缺乏研究。这项研究的主要目的是调查人口方面(组成,多样性,性别比例)和生态方面(出现模式,PlitviceLakesNP15年以上的Scirtidae家族的季节性动态和对环境因素的偏好,克罗地亚。该研究在三个地点和五种不同的底物类型中进行。在研究区域中总共记录了三个具有不同分布的分类单元:在凝灰岩屏障和Elodessp。在春季地区。在春季和初夏,性别比对男性有利,而在秋末,它转向了对女性的青睐。家庭的丰富和出现主要取决于环境参数,这些参数在15年内表现出最大的波动:水温,水排放和氧饱和度。我们的结果清楚地表明,Scirtidae可以用作河流分区和栖息地质量的指标。根据本研究的方法和结果,我们得出结论,应在东南欧喀斯特淡水栖息地的未来监测和保护措施中使用Scirtidae。
    Due to ongoing changes and a decline in biodiversity, science today should rely on long-term species-based ecological studies. We have conducted a long-term ecological dynamics study on the water beetle family Scirtidae, which, although it is very abundant in benthic communities, is still poorly studied. The main objective of this study was to investigate the population aspects (composition, diversity, sex ratio) and ecological aspects (emergence patterns, seasonal dynamics and preferences for environmental factors) of the family Scirtidae over 15 years in Plitvice Lakes NP, Croatia. The study was conducted at three sites and in five different substrate types. A total of three taxa with different distributions were recorded in the study area: Hydrocyphon novaki and H. deflexicollis on the tufa barriers and the Elodes sp. in the spring area. The sex ratio was in favour of males in spring and early summer, while it shifted in favour of females towards the end of autumn. The abundance and emergence of the family were primarily determined by the environmental parameters which showed the greatest fluctuations over a period of 15 years: water temperature, water discharge and oxygen saturation. Our results clearly show that Scirtidae can be used as indicators of stream zonation and habitat quality. Based on the methodology and the results of this study, we conclude that Scirtidae should be used in future monitoring and protection measures in karst freshwater habitats in southeastern Europe.
