    药学教育转向基于能力的培训,以满足医疗保健需求。本研究旨在为药剂师开发和验证科威特高级能力框架(KACF)。该研究采用了FIP全球先进发展框架(GADF)来制定针对特定国家的框架,强调与全球标准保持一致,同时适应当地环境的重要性。所开发的框架以科威特基金会能力框架为基础,以满足对高级药房服务的需求。
    这是一项混合方法研究,采用了“采用和适应”方法。KACF是从FIPGADF采用的,并在四个阶段进行了调整。第一阶段涉及检查和验证FIPGADF的阿拉伯语版本。第二阶段采用了一系列焦点小组来验证能力陈述的准确性和相关性。第三阶段利用与不同利益相关者的研讨会作为验证的最后一步。第四阶段涉及一项全国调查,以根据框架能力评估国家药房劳动力。来自焦点小组和研讨会的定性反馈告知能力修改。使用描述性和多重对应分析(MCA)分析定量数据。
    翻译阶段验证了一种双语框架,可供科威特的药剂师使用。初始和最终验证阶段确定了与科威特药房实践相关的20项行为陈述(原始文件中的22项)。全国调查,由169名受访者组成,验证了KACF的适用性,揭示了不同能力集群的职业阶段进展的变化。调查结果强调了职业阶段和实践设置之间的关联,为量身定制的劳动力发展战略提供见解。
    KACF成为推进科威特药房服务的关键工具,与基于能力的教育的全球趋势保持一致。研究结果强调了在推进药学实践中采用针对具体情况的方法的必要性。全面了解高级角色的能力进展和准备情况。
    UNASSIGNED: Pharmacy education shifts toward competency-based training to meet healthcare demands. This study aims to develop and validate the Kuwait Advanced Competency Framework (KACF) for pharmacists. The study adopts the FIP Global Advanced Development Framework (GADF) to develop a country-specific framework, emphasizing the importance of aligning with global standards while adapting to local contexts. The developed framework builds upon the Kuwait Foundation Competency Framework to address the need for advanced pharmacy services.
    UNASSIGNED: This is a mixed methods study that employed an \"adopt and adapt\" approach. The KACF was adopted from the FIP GADF and adapted following four phases. Phase one involved checking and validating the Arabic version of the FIP GADF. Phase two employed a series of focus groups to validate accuracy and relevancy of competency statements. Phase three utilized a workshop with different stakeholders as a final step of validation. Phase four involved a national survey to assess the national pharmacy workforce against the framework competencies. Qualitative feedback from focus groups and workshops informed competencies modifications. Quantitative data were analyzed using descriptive and multiple correspondence analyses (MCA).
    UNASSIGNED: The translation phase verified a bilingual framework that could be utilized by pharmacists in Kuwait. The initial and final validation phases identified 20 behavioral statements (out of 22 in the original document) that are relevant to pharmacy practice in Kuwait. The national survey, comprising 169 respondents, validated the KACF\'s applicability, revealing variations in career stage progression across competency clusters. Findings highlighted associations between career stages and practice settings, offering insights for tailored workforce development strategies.
    UNASSIGNED: The KACF emerges as a pivotal tool for advancing pharmacy services in Kuwait, aligning with global trends toward competency-based education. Findings underscored the necessity for context-specific approaches in advancing pharmacy practice, providing a comprehensive understanding of competency progression and readiness for advanced roles.

    研究人员和从业人员通常熟悉描述性统计和统计推断。然而,在回归技术之外,人们可能很少关注预测周围的问题。在当前的论文中,我们使用在描述性和推断性统计训练中学习的基本概念引入预测区间(即,抽样误差,标准偏差)。我们使用简单的手工计算来遍历一个示例,并引用一个可用于计算预测间隔的简单R包。
    Researchers and practitioners are typically familiar with descriptive statistics and statistical inference. However, outside of regression techniques, little attention may be given to questions around prediction. In the current paper, we introduce prediction intervals using fundamental concepts that are learned in descriptive and inferential statistical training (i.e., sampling error, standard deviation). We walk through an example using simple hand calculations and reference a simple R package that can be used to calculate prediction intervals.

    医学科学必须基于可靠和科学的证据,并需要持续的研究。从事研究可以让学生和教师探索新的领域,质疑现有的范式,并发现医疗挑战的创新解决方案。作为特产,社区医学在解决公共卫生问题方面发挥着关键作用。然而,社区医学居民在生物医学研究中的参与度仍然欠佳,这可能会阻碍针对印度背景的循证实践的产生。这项研究是为了寻找社区医学居民的兴趣和参与度,以及影响他们对生物医学研究兴趣的因素。方法对北方邦社区医疗居民进行在线调查,从2024年2月到4月,使用具有半结构化的GoogleForms,预先测试的问卷。结果一百九十六名居民参与研究,其中女性(52.6%;103/196)超过男性(47.4%;93/196)。大多数参与者是三年级居民(40.8%)。大多数参与者似乎对生物医学研究感兴趣(83.2%),并认为生物医学研究基础课程(BCBR)有助于开展研究项目(75%)。大约一半的人以前有研究项目的经验,横断面研究是最常见的(75.9%)研究设计。提高研究技能和为医学知识做出贡献的愿望成为主要动力。另一方面,由于学术和教育活动负担过重而缺乏时间被视为进行研究的最常见障碍。结论发现大多数参与者对研究活动感兴趣。提高研究技能的机会,渴望为医疗兄弟会服务,对简历的积极影响是进行研究的主要激励因素。难以节省时间,小知识,导师的不良支持被认为是重要的障碍。
    Introduction Medical science must be based on sound and scientific evidence and requires continuous research. Engaging in research allows students and faculty to explore new frontiers, question existing paradigms, and discover innovative solutions to medical challenges. As a specialty, community medicine plays a pivotal role in addressing public health issues. However, the engagement of community medicine residents in biomedical research remains suboptimal, which may impede the generation of evidence-based practices tailored to the Indian context. This study was conducted to find the interest and engagement of community medicine residents, and factors influencing their interest in biomedical research. Methods An online survey was conducted among community medicine residents of Uttar Pradesh, from February to April 2024, using Google Forms having a semi-structured, pretested questionnaire. Results One hundred and ninety-six residents participated in the study, where females (52.6%; 103/196) outnumbered males (47.4%; 93/196). The majority of participants were third-year residents (40.8%). Most participants seemed interested in biomedical research (83.2%) and thought that Basic Course in Biomedical Research (BCBR) helps conduct research projects (75%). Around half had previous experience in research projects, with cross-sectional studies being the most common (75.9%) study design. Enhancing research skills and a desire to contribute to medical knowledge emerged as primary motivators. On the other hand, the lack of time due to being overburdened with academic and educational activities was seen as the most common barrier to conducting research. Conclusions The majority of participants were found interested in research activities. The opportunity to improve research skills, desire to serve the medical fraternity, and a positive impact on resumes were the leading motivating factors for conducting research. Difficulty in sparing time, little knowledge, and poor support from mentors were found as important barriers.

    目标:脆弱性指数(FI),即从“事件”到“非事件”的状态变化导致统计显著性丧失的最小次数,作为临床医师解释临床试验结果的重要补充指标,并有助于理解随机对照试验(RCTs)的结果.在这个系统的文献调查中,我们评估了评价中药(CHM)对肠易激综合征(IBS),并探讨了研究特征与随机对照试验的稳健性之间的潜在关联。
    方法:从成立到2023年1月1日,在四个中文数据库和四个英文数据库中进行了全面搜索。RCTs将1:1的比例纳入两个平行的组,并且报道了至少一个显示统计学显著性的二元结果。FI是通过在治疗组中反复减少目标结果事件并同时从该组中减去非目标事件来计算的。直至失去正显著性(Fisher精确检验定义为P<0.05)。试验结果的FI越低(最小1),结果的积极结果越脆弱。采用线性回归模型探讨FI值的影响因素。
    结果:最终纳入了24118篇潜在相关引文中的30项试验。纳入的全部试验的中位FI为1.5(四分位数间距[IQR],1-5),一半的试验(n=15)的FI等于1。在12项试验中(40%),失去随访的参与者总数超过了各自的FI.该研究还发现,患者的纳入标准与无中医辨证显著相关,总样本量更大,低偏见风险,和更多的事件。
    结论:发现大多数结果阳性的CHMIBS随机对照试验是脆弱的。确保足够的样本量,科学严谨的学习设计,适当控制混杂因素,应针对临床医生之间中医诊断结果的一致性进行质量控制校准,以提高随机对照试验的稳健性。我们建议在未来的随机对照试验中报告FI作为敏感性分析的组成部分之一,以促进对试验脆弱性的评估。
    OBJECTIVE: The fragility index (FI), which is the minimum number of changes in status from \"event\" to \"non-event\" resulting in a loss of statistical significance, serves as a significant supplementary indicator for clinical physicians in interpreting clinical trial results and aids in understanding the outcomes of randomized controlled trials (RCTs). In this systematic literature survey, we evaluated the FI for RCTs evaluating Chinese herbal medicine (CHM) for irritable bowel syndrome (IBS), and explored potential associations between study characteristics and the robustness of RCTs.
    METHODS: A comprehensive search was conducted in four databases in Chinese and four databases in English from their inception to January 1, 2023. RCTs encompassed 1:1 ratio into two parallel arms and reported at least one binary outcome that demonstrated statistical significance were included. FI was calculated by the iterative reduction of a target outcome event in the treatment group and concomitant subtraction of a non-target event from that group, until positive significance (defined as P < 0.05 by Fisher\'s exact test) is lost. The lower the FI (minimum 1) of a trial outcome, the more fragile the positive result of the outcome was. Linear regression models were adopted to explore influence factors of the value of FI.
    RESULTS: A total of 30 trials from 2 4118 potentially relevant citations were finally included. The median FI of total trials included was 1.5 (interquartile range [IQR], 1-5), and half of the trials (n = 15) had a FI equal to 1. In 12 trials (40%), the total number of participants lost to follow-up surpassed the respective FI. The study also identified that increased FI was significantly associated with no TCM syndrome differentiation for inclusion criteria of the patients, larger total sample size, low risk of bias, and larger numbers of events.
    CONCLUSIONS: The majority of CHM IBS RCTs with positive results were found to be fragile. Ensuring adequate sample size, scientifically rigorous study design, proper control of confounding factors, and a quality control calibration for consistency of TCM diagnostic results among clinicians should be addressed to increase the robustness of the RCTs. We recommend reporting the FI as one of the components of sensitivity analysis in future RCTs to facilitate the assessment of the fragility of trials.

    牙周炎与许多生活方式疾病独立相关。糖尿病患者患牙周炎的几率增加了大约三倍,这反过来又增加了全身性炎症的风险。ThazhePoyil等人的研究旨在根据患有和不患有糖尿病的糖尿病患者的牙周发炎的表面积,建立糖尿病性视网膜病变(DR)与牙周炎之间的炎症联系。为了进一步推进这项研究,我们建议完善合格标准,明确说明牙周炎和DR的临床相关性,更大的样本量和改进的抽样方法,两组基线特征匹配,以及改进的统计方法和对研究结果的解释。在比较有或没有牙周炎的严重程度匹配的2型糖尿病患者的研究中,血红蛋白A1c(HbA1c)的测量可以更清晰地了解HbA1c水平是否确实受到牙周炎的影响。
    Periodontitis is independently associated with numerous lifestyle diseases. Diabetic patients have approximately threefold increased odds of periodontitis, which in turn increases the risk of systemic inflammation. The study by Thazhe Poyil et al is an effort to establish the inflammatory link between diabetic re-tinopathy (DR) and periodontitis based on the periodontal inflamed surface area in diabetic patients with and without DR. To further advance the study, we suggest refining the eligibility criteria to explicitly state the clinical correlates of periodontitis and DR, larger sample size and improved sampling methodology, matching of baseline characteristics of the two groups, as well as improved statistical approach and interpretation of the study findings. Measurement of hemoglobin A1c (HbA1c) in studies comparing type 2 diabetes mellitus patients with DR of matched severity with and without periodontitis could provide a clearer picture of whether HbA1c level is indeed influenced by periodontitis.

    背景:深度访谈是定性数据收集的常用方法,提供关于个人的观念和行为的丰富数据,用定量方法收集这些数据将是具有挑战性的。研究人员通常需要事先决定样本量。尽管研究已经评估了何时达到饱和,对于达到饱和所需的最低采访次数没有达成一致。迄今为止,大多数关于饱和度的研究都是基于现场数据收集。在COVID-19大流行期间,基于网络的数据收集变得越来越普遍,因为传统的面对面数据收集是可能的。研究人员在COVID-19紧急情况后继续使用基于网络的数据收集方法,这使得重要的是评估饱和的结果是否在面对面采访和基于网络的采访中有所不同。
    目的:我们旨在确定实现真正代码饱和或接近代码饱和所需的基于网络的访谈数量。
    方法:本研究的分析基于5项食品和药物管理局资助的研究的数据,这些研究是通过基于网络的平台进行的,这些平台对患有潜在医疗状况的患者或对患者提供初级或专科护理的医疗保健提供者进行的。我们提取了特定于代码和访谈的数据,并检查数据摘要,以确定何时达到真正的饱和或接近饱和。
    结果:5项研究中使用的样本量范围为30至70次访谈。经过91%至100%(n=30-67)的计划面试后达到真正的饱和度,而在计划访谈的33%至60%(n=15-23)后达到接近饱和.严重依赖演绎编码的研究和具有更结构化访谈指南的研究更快地达到了真正的饱和和接近饱和。我们还检查了在达到接近饱和后应用的代码类型。在5项研究中的4项,这些代码中的大多数代表了以前建立的核心概念或主题。代表新确定的概念的代码,其他或杂项回应(例如,\"ingeneral\"),不确定性或困惑(例如,\“不知道\”),或用于分析的分类(例如,与不正确的相比,正确的)在达到接近饱和后较不常见。
    结论:这项研究提供了支持,即接近饱和可能是一个足够的指标,并且在这一点之后进行额外的访谈可能会导致收益递减。在决定进行多少次面试时要考虑的因素包括面试指南中包含的问题的结构和类型,编码结构,和正在研究的人口。具有较少的结构化面试指南的研究,严重依赖归纳编码和分析技术的研究,以及包括可能对所讨论主题了解较少的人群的研究可能需要更大的样本量才能达到可接受的饱和水平。我们的发现还建立在先前的研究基础上,这些研究着眼于在少数地点进行的现场数据收集的饱和度。
    BACKGROUND: In-depth interviews are a common method of qualitative data collection, providing rich data on individuals\' perceptions and behaviors that would be challenging to collect with quantitative methods. Researchers typically need to decide on sample size a priori. Although studies have assessed when saturation has been achieved, there is no agreement on the minimum number of interviews needed to achieve saturation. To date, most research on saturation has been based on in-person data collection. During the COVID-19 pandemic, web-based data collection became increasingly common, as traditional in-person data collection was possible. Researchers continue to use web-based data collection methods post the COVID-19 emergency, making it important to assess whether findings around saturation differ for in-person versus web-based interviews.
    OBJECTIVE: We aimed to identify the number of web-based interviews needed to achieve true code saturation or near code saturation.
    METHODS: The analyses for this study were based on data from 5 Food and Drug Administration-funded studies conducted through web-based platforms with patients with underlying medical conditions or with health care providers who provide primary or specialty care to patients. We extracted code- and interview-specific data and examined the data summaries to determine when true saturation or near saturation was reached.
    RESULTS: The sample size used in the 5 studies ranged from 30 to 70 interviews. True saturation was reached after 91% to 100% (n=30-67) of planned interviews, whereas near saturation was reached after 33% to 60% (n=15-23) of planned interviews. Studies that relied heavily on deductive coding and studies that had a more structured interview guide reached both true saturation and near saturation sooner. We also examined the types of codes applied after near saturation had been reached. In 4 of the 5 studies, most of these codes represented previously established core concepts or themes. Codes representing newly identified concepts, other or miscellaneous responses (eg, \"in general\"), uncertainty or confusion (eg, \"don\'t know\"), or categorization for analysis (eg, correct as compared with incorrect) were less commonly applied after near saturation had been reached.
    CONCLUSIONS: This study provides support that near saturation may be a sufficient measure to target and that conducting additional interviews after that point may result in diminishing returns. Factors to consider in determining how many interviews to conduct include the structure and type of questions included in the interview guide, the coding structure, and the population under study. Studies with less structured interview guides, studies that rely heavily on inductive coding and analytic techniques, and studies that include populations that may be less knowledgeable about the topics discussed may require a larger sample size to reach an acceptable level of saturation. Our findings also build on previous studies looking at saturation for in-person data collection conducted at a small number of sites.

    在计算方法发展的时候,通常与现在备受吹捧的机器学习(ML)和人工智能(AI)术语联系在一起,在公平方面面临越来越多的挑战,透明度和问责制,研究人员将主流ML方法应用于几乎任何类型的数据的诱惑似乎仍然无法抗拒。在本文中,我们批判性地研究了最近提出的将ML应用于测谎仪筛查结果的建议(其中人类采访者已经得出了关于欺骗的结论),这对研究的目的和设计提出了几个问题,特别是考虑到基于测谎仪的程序本身的空虚科学地位。我们认为,在刑事司法和就业实践等高风险环境中,在基本权利和正义原则受到威胁的地方,科学研究的法律和道德考虑得到了加强。具体来说,我们认为,模糊标记的数据和临时机器学习模型的组合不符合这一要求。更糟糕的是,这样的研究可能会不恰当地合法化,否则在科学上是无效的,实际上是伪科学方法,如基于测谎仪的欺骗检测,特别是当在一个著名的科学期刊上发表时。我们得出的结论是,方法论上的关注,如本文所强调的,在研究可以说有助于解决法律诉讼中使用的方法和技术的任何基本有效性问题之前,应该予以解决。
    At a time when developments in computational approaches, often associated with the now much-vaunted terms Machine Learning (ML) and Artificial Intelligence (AI), face increasing challenges in terms of fairness, transparency and accountability, the temptation for researchers to apply mainstream ML methods to virtually any type of data seems to remain irresistible. In this paper we critically examine a recent proposal to apply ML to polygraph screening results (where human interviewers have made a conclusion about deception), which raises several questions about the purpose and the design of the research, particularly given the vacuous scientific status of polygraph-based procedures themselves. We argue that in high-stake environments such as criminal justice and employment practice, where fundamental rights and principles of justice are at stake, the legal and ethical considerations for scientific research are heightened. Specifically, we argue that the combination of ambiguously labelled data and ad hoc ML models does not meet this requirement. Worse, such research can inappropriately legitimise otherwise scientifically invalid, indeed pseudo-scientific methods such as polygraph-based deception detection, especially when presented in a reputable scientific journal. We conclude that methodological concerns, such as those highlighted in this paper, should be addressed before research can be said to contribute to resolving any of the fundamental validity issues that underlie methods and techniques used in legal proceedings.

    研究的基本概念是通过系统的文献检索学习的,这些文献构成了研究陈述和研究主题的基础。然后是研究问题,假设,目标,和目标,以及实验设计,是开发的。鉴于所提供的上下文,主要重点是在研究方法和项目开发方面充分培训研究生和年轻研究人员的重要性。显然,在这些方面缺乏适当的培训,印度大学的迅速扩张加剧了这个问题。为了解决这个问题,研究型学生必须接受全面的科研方法论指导,实验设计,统计数据,科学写作,出版,和研究伦理。我们的团队已经举办了二十多年的研讨会和座谈会,以改善这些领域的现有教学方法。最近,我们在印度多个州组织了一系列国家和国际研讨会,以巩固学生和教职员工的科学研究核心概念。本报告重点介绍了这些研讨会的关键方面以及参与者所取得的积极成果。
    The basic concepts of research are learned through systematic literature searches which form the basis of a research statement and research topic. Then the research question, hypothesis, aim, and objectives, as well as the experimental design, are developed. Given the context provided, the primary focus is on the importance of adequately training postgraduates and young research investigators in research methodology and project development. It is evident that there is a lack of proper training in these areas, and the rapid expansion of colleges in India exacerbates this issue. To address this, research students must receive comprehensive instruction in scientific research methodology, experimental design, statistics, scientific writing, publishing, and research ethics. Our team has been conducting workshops and symposia for more than two decades to improve the current teaching methods in these areas. Most recently, we organized a series of national and international workshops and seminars in multiple states across India to fortify the core concepts of scientific research for students and faculty members. This report highlights the key aspects of these workshops and the positive outcomes experienced by participants.
