    在一些国家,药剂师已经获得了处方权利,以提高护理质量和可及性,并减少医生的工作量。本案例研究探讨了药剂师在荷兰初级保健中的当前角色和潜在处方,不存在药剂师的处方权。对在普通实践或社区药房工作的药剂师进行了参与性观察,以及关于当前和潜在实践的半结构化访谈。后者扩展到患者和其他医疗保健专业人员,主要是全科医生,总共进行了34次面试。主题分析表明,药剂师,在所有情况下,写处方,然后在配药前由医生授权。基于一般实践的药剂师经常在患者咨询期间开处方。社区药剂师主要通过(a)药物审查来影响处方,其中医生和/或执业护士经常被咨询以做出治疗决定,(b)与医生达成合作协议,以在特定情况下开始或替代药物。这些发现表明,药剂师目前在荷兰处方中的作用类似于其他国家的协作处方实践。我们还确定了在正式介绍药剂师处方之前应该解决的几个问题,例如任务和责任的定义以及针对药剂师的处方特定培训。
    In some countries, pharmacists have obtained prescribing rights to improve quality and accessibility of care and reduce physician workload. This case study explored pharmacists\' current roles in and potential for prescribing in primary care in the Netherlands, where prescribing rights for pharmacists do not exist. Participatory observations of pharmacists working in either general practice or community pharmacy were conducted, as were semi-structured interviews about current and potential practice. The latter were extended to patients and other healthcare professionals, mainly general practitioners, resulting in 34 interviews in total. Thematic analyses revealed that pharmacists, in all cases, wrote prescriptions that were then authorized by a physician before dispensing. General practice-based pharmacists often prescribed medications during patient consultations. Community pharmacists mainly influenced prescribing through (a) medication reviews where the physician and/or practice nurse often were consulted to make treatment decisions, and (b) collaborative agreements with physicians to start or substitute medications in specific situations. These findings imply that the pharmacists\' current roles in prescribing in the Netherlands resemble collaborative prescribing practices in other countries. We also identified several issues that should be addressed before formally introducing pharmacist prescribing, such as definitions of tasks and responsibilities and prescribing-specific training for pharmacists.

    成团的泛菌,革兰氏阴性细菌,已经成为一种机会病原体,特别是在新生儿医疗机构中。最初被认为是无害的环境污染物,成团假单胞菌越来越多地参与一系列临床感染,包括新生儿败血症和菌血症。本系统综述对2003-2023年发表的临床病例进行了深入分析,阐明了与新生儿成群假单胞菌感染相关的多方面临床表现和治疗挑战。总的来说,包括来自八个不同国家的11例病例报告和45例新生儿病例系列。大多数感染患者(57.8%)在亚洲国家(斯里兰卡,印度,科威特),并涉及极低至低出生体重的早产儿(64.4%),以及并发的医疗状况,包括其中一些(15.6%)的合并感染。血液是病原体的主要培养源,占42例(91.1%),而新生儿的临床表现表现出相当大的异质性,包括常见的症状,如喂养困难,呼吸窘迫,发烧,嗜睡,还有败血症.新生儿的生存在很大程度上取决于感染的起源和诊断的时机。将抗生素敏感性作为治疗选择的标准导致74%的存活率。通常,使用了抗生素的组合。报告有11例新生儿死亡,导致估计死亡率为24.4%。我们得出的结论是,新生儿重症监护病房内的暴发强调了严格的感染控制措施和加强监测的重要性,特别是考虑到纳入的研究中提到的快速疾病进展。增强对聚集假单胞菌感染的临床和微生物学特征的认识和理解对于优化结果和减轻新生儿人群的疾病负担至关重要。
    Pantoea agglomerans, a gram-negative bacterium, has emerged as an opportunistic pathogen, particularly within neonatal healthcare settings. Initially perceived as an innocuous environmental contaminant, P. agglomerans has been increasingly implicated in a spectrum of clinical infections, including neonatal sepsis and bacteremia. This systematic review conducts an in-depth analysis of the clinical cases published in 2003-2023, elucidating the multifaceted clinical presentations and therapeutic challenges associated with P. agglomerans infections in neonates. In total, 11 case reports and case series of 45 neonates from eight different countries were included. Most of the infected patients (57.8%) were reported in Asian countries (Sri Lanka, India, Kuwait) and involved preterm neonates (64.4%) with extremely low to low birth weight, and concurrent medical conditions including co-infections in a few of them (15.6%). Blood was the main culture source of the pathogen, accounting for 42 cases (91.1%) whereas clinical presentations in neonates exhibited considerable heterogeneity, encompassing common symptoms such as feeding difficulties, respiratory distress, fever, lethargy, and sepsis. Neonatal survival largely depended on the infection\'s origin and the timing of diagnosis. Considering antibiotic susceptibility as a criterion for treatment selection led to a 74% survival rate. Usually, a combination of antibiotics was used. There were 11 neonatal deaths reported, leading to an estimated mortality rate of 24.4%. We conclude that outbreaks within neonatal intensive care units underscore the importance of stringent infection control practices and heightened surveillance, especially considering the rapid disease progression noted in the included studies. Enhanced awareness and understanding of the clinical and microbiological characteristics of P. agglomerans infections are paramount for optimizing outcomes and reducing the burden of disease in neonatal populations.

    背景:智力障碍是一种神经发育障碍,其特征是智力功能和适应性行为明显受损。认知灵活性和注意力是智力障碍儿童经常受到影响的关键认知领域。本病例报告探讨了经颅交流电刺激的新颖用途,一种无创的大脑刺激技术,来增强这些认知功能。该研究的新颖性在于其专注于针对特定Brodmann区域的α波频率经颅交流刺激,及其对智障儿童人群的认知灵活性和注意力的潜在持续影响。
    方法:案例研究涉及两名小学生,都是7岁有轻度智力障碍,一男一女,都是突厥民族,来自Khosrowshah的ShahidFahmideh特殊儿童学校,伊朗。两位参与者都接受了为期2周的干预,每天以α波频率(10Hz)进行20分钟的经颅交流电刺激,瞄准Brodmann区域F3和P3。使用威斯康星卡片分类测试和时钟测试评估认知灵活性和注意力,在四个时间点进行管理:干预前,干预后第1周、第2周和第1个月。统计分析显示,与基线相比,两位参与者的威斯康星卡片分类测试和时钟测试得分均有显着改善。随着时间的推移持续增强。
    结论:该病例报告的结果表明,经颅交流刺激可能是改善智力障碍儿童认知灵活性和注意力的有希望的干预措施。观察到的显着和持续的改善表明,经颅交流电刺激可能对该人群的认知发展产生有意义的临床影响。然而,需要进一步的研究来证实经颅交流电流刺激的功效,并探索其更广泛的适用性和长期效果,更多样化的人口。
    BACKGROUND: Intellectual disability is a neurodevelopmental disorder characterized by significant impairments in intellectual functioning and adaptive behavior. Cognitive flexibility and attention are crucial cognitive domains often affected in children with intellectual disability. This case report explores the novel use of transcranial alternating current stimulation, a noninvasive brain stimulation technique, to enhance these cognitive functions. The study\'s novelty lies in its focus on alpha-wave frequency transcranial alternating current stimulation targeting specific Brodmann areas and its potential sustained impact on cognitive flexibility and attention in the pediatric population with intellectual disability.
    METHODS: The case study involved two elementary school students, both 7 years old with mild intellectual disability, one male and one female, both with Turkic ethnicity, from Shahid Fahmideh School for Exceptional Children in Khosrowshah, Iran. Both participants underwent a 2-week intervention with daily 20-minute sessions of transcranial alternating current stimulation at an alpha-wave frequency (10 Hz), targeting Brodmann areas F3 and P3. Cognitive flexibility and attention were assessed using the Wisconsin Card Sorting Test and the Clock Test, administered at four time points: pre-intervention, week 1, week 2, and 1 month post-intervention. Statistical analysis showed significant improvements in both Wisconsin Card Sorting Test and Clock Test scores for both participants compared with baseline, with sustained enhancement over time.
    CONCLUSIONS: The findings from this case report indicate that transcranial alternating current stimulation may be a promising intervention for improving cognitive flexibility and attention in children with intellectual disability. The significant and sustained improvements observed suggest that transcranial alternating current stimulation could have a meaningful clinical impact on the cognitive development of this population. However, further research is needed to confirm the efficacy of transcranial alternating current stimulation and to explore its broader applicability and long-term effects in larger, more diverse populations.

    目的:精神药物的临床使用涉及多种风险,可通过护理干预来解决。该研究有双重目的:制定“循证药物治疗管理指南”和“药物管理跟踪图表”,并通过评估性案例研究评估其使用情况。
    方法:循证指南和图表开发以及评估案例研究。最初,开发了用于在精神科管理药物的循证药物治疗管理指南和药物管理跟踪图表。随后,在一项案例研究中评估了他们的疗效,该研究涉及10名参与护士,这些护士在土耳其一家培训和研究医院拥有123张床位的精神科使用.数据是通过个人形式收集的,采访,用药图表,和研究人员的观察,分析采用了梅里亚姆的案例研究方法。
    结果:三个主题(开始,实施,终止,和维持者)和12个子主题出现了。护士表示,研究工具填补了他们的信息空白,提高药物治疗管理过程的有效性和安全性,提高护理质量和连续性,并使患者受益。护士表示希望始终如一地使用该单元中的工具并提供建议。
    结论:护士强调了提高用药安全性的潜在工具,精神病治疗,和患者结果。然而,他们使用循证工具的立场揭示了一种方法/避免冲突,平衡利益和障碍。经验成为接受循证临床工具的障碍。这项研究是在全球和我国率先全面制定针对精神科护士的循证用药管理指南和管理跟踪图的研究之一。这些工具的常规使用有望提高护士在精神药物管理方面的专业知识,导致改善患者在药物相关方面的结果。
    OBJECTIVE: Clinical use of psychotropic medications involves diverse risks, addressable by nursing interventions. The research had a dual purpose: developing an \"Evidence-Based Medication Therapy Management Guideline\" and a \"Medication Administration-Tracking Chart\" and evaluating their use through an evaluative case study.
    METHODS: Evidence-based guideline and chart development and evaluative case study. Initially, Evidence-Based Medication Therapy Management Guideline and Medication Administration Tracking Chart for managing medication in a psychiatric unit were developed. Subsequently, their efficacy was evaluated in a case study involving 10 participating nurses used in the psychiatric unit with 123-bed of a training and research hospital in Turkey. Data was collected through personal forms, interviews, medication charts, and researcher observations, and the analysis employed Merriam\'s case study method.
    RESULTS: Three themes (inception, implementation, termination, and sustainers) and 12 sub-themes emerged. Nurses stated that the research tools filled their information gaps, enhancing the medication therapy management process\'s effectiveness and safety, improving nursing care quality and continuity, and benefiting patient outcomes. Nurses expressed a desire to consistently use the tools in the unit and provided suggestions.
    CONCLUSIONS: Nurses highlighted the tools\' potential to enhance medication safety, psychiatric care, and patient outcomes. However, their stance on using evidence-based tools revealed an approach/avoidance conflict, balancing benefits and barriers. Experience emerged as a hindrance in embracing evidence-based clinical tools. This study is among the first to comprehensively develop evidence-based medication management guideline and administration-tracking chart for psychiatric nurses globally and in our country. Routine use of the tools is expected to enhance nurses\' expertise in psychotropic medication management, leading to improved patient outcomes in medication-related aspects.

    在第一波COVID-19疫情期间,中国表现出了对流行病预防和控制的坚定承诺。本案例研究集中在Z大学,在疫情严重时采取封闭管理,通过对10名学生的访谈,考察了COVID-19对学生心理和行为的影响。研究表明,虽然学生认为疫情期间的封闭式管理在一定程度上提高了安全性,促进了学习参与度,这种流行病也对他们的身体健康产生不利影响,心理学,和社交生活。这些影响包括身体健康恶化,关于大学生活的叛逆和沮丧的感觉,以及对未来工作稳定性的担忧和愿望。在讨论中,我们建议高等教育机构可以利用这些信息来制定政策和程序,特别是关于心理健康和风险沟通,不仅在当前的大流行期间,而且在未来的紧急情况或灾难情况下。
    During the first wave of COVID-19, China demonstrated a strong commitment to epidemic prevention and control. This case study focuses on Z University, which adopted closed management when the epidemic was serious, and examines the influence of COVID-19 on students\' psychology and behavior through interviews with 10 students. The research reveals that while students perceive closed management during the epidemic as enhancing safety and promoting learning engagement to some extent, the epidemic also has adverse effects on their physical health, psychology, and social life. These impacts included deteriorating physical health, feelings of rebellion and depression regarding college life, alongside concerns and aspirations regarding future job stability. In the discussion, we suggest that higher education institutions can utilize this information to shape policies and procedures, particularly concerning mental health and risk communication, not only during the current pandemic but also in future emergency or disaster scenarios.

    背景:命名实体识别(NER)是自然语言处理中的一项基本任务。然而,它之前通常是命名实体注释,这带来了一些挑战,尤其是在临床领域。例如,确定实体边界是注释者之间最常见的分歧来源之一,因为诸如是否应该注释修饰语或外围词。如果未解决,这些会导致产生的语料库不一致,然而,另一方面,严格的指导方针或裁决会议可以进一步延长已经缓慢和复杂的过程。
    目的:本研究的目的是通过评估两种新颖的注释方法来解决这些挑战,宽松的跨度和点注释,旨在减轻精确确定实体边界的难度。
    方法:我们通过对日本医学病例报告数据集的注释案例研究来评估其效果。我们比较注释时间,注释者协议,和生成的标签的质量,并评估对在注释的语料库上训练的NER系统的性能的影响。
    结果:我们看到了标签过程效率的显着提高,与传统的边界严格方法相比,整体注释时间减少了25%,注释者协议甚至提高了10%。然而,与传统的注释方法相比,即使是最好的NER模型也表现出一些性能下降。
    结论:我们的发现证明了注释速度和模型性能之间的平衡。尽管忽略边界信息会在一定程度上影响模型性能,这是由显著减少注释者的工作量和显著提高注释过程的速度所抵消的。这些好处可能在各种应用中被证明是有价值的,为开发人员和研究人员提供了一个有吸引力的折衷方案。
    BACKGROUND: Named entity recognition (NER) is a fundamental task in natural language processing. However, it is typically preceded by named entity annotation, which poses several challenges, especially in the clinical domain. For instance, determining entity boundaries is one of the most common sources of disagreements between annotators due to questions such as whether modifiers or peripheral words should be annotated. If unresolved, these can induce inconsistency in the produced corpora, yet, on the other hand, strict guidelines or adjudication sessions can further prolong an already slow and convoluted process.
    OBJECTIVE: The aim of this study is to address these challenges by evaluating 2 novel annotation methodologies, lenient span and point annotation, aiming to mitigate the difficulty of precisely determining entity boundaries.
    METHODS: We evaluate their effects through an annotation case study on a Japanese medical case report data set. We compare annotation time, annotator agreement, and the quality of the produced labeling and assess the impact on the performance of an NER system trained on the annotated corpus.
    RESULTS: We saw significant improvements in the labeling process efficiency, with up to a 25% reduction in overall annotation time and even a 10% improvement in annotator agreement compared to the traditional boundary-strict approach. However, even the best-achieved NER model presented some drop in performance compared to the traditional annotation methodology.
    CONCLUSIONS: Our findings demonstrate a balance between annotation speed and model performance. Although disregarding boundary information affects model performance to some extent, this is counterbalanced by significant reductions in the annotator\'s workload and notable improvements in the speed of the annotation process. These benefits may prove valuable in various applications, offering an attractive compromise for developers and researchers.

    本案例研究利用整体生态方法(HEA)来探索中国成功的运动人才培养环境(ATDE)。作为一个案例,我们在上海一所体育友好型高中中选择了一支具有杰出个人和团队成就的篮球队,旨在(a)描述ATDE,(b)确定环境成功因素(ESF)。使用参与者的观察,文档分析,非正式会谈,以及与主要利益相关者的正式访谈,包括教练,教师,运动员,以及体育和教育部门的管理人员,我们推导了ATDE和ESF经验模型。研究结果表明,(a)ATDE展示了宏观和微观层面之间的有效相互作用,和(b)经验丰富的总教练,敬业的助理教练,运动员父母的支持有助于克服先决条件的障碍(例如,有限的财政和人力资源)。Further,由总教练领导的连贯和强大的文化范式帮助环境长期保持成功。尽管某些功能与其他国家/地区的成功ATDE相似,独特的特征(例如,在中国文化背景下,不优先考虑运动员的自主权)已确定。我们的发现补充了目前使用HEA对ATDE的研究,并反映了中国背景下的环境,为研究人员和从业人员提供见解。
    This case study utilized the holistic ecological approach (HEA) to explore a successful athletic talent development environment (ATDE) in China. As a case, we selected a basketball team in one Shanghai sport-friendly high school with outstanding individual and team achievements and aimed at (a) describing the ATDE, and (b) identifying environmental success factors (ESF). Using participant observations, document analysis, informal talks, and formal interviews with key stakeholders, including coaches, teachers, athletes, and administrators from sports and education departments, we derived the ATDE and ESF empirical models. The findings showed that (a) the ATDE demonstrated effective interactions between macro- and micro-levels, and (b) the experienced head coach, dedicated assistant coach, and support from athletes\' parents contributed to overcoming barriers of preconditions (e.g., limited financial and human resources) within the environment. Further, a coherent and robust cultural paradigm led by the head coach helped the environment maintain its success for a long period. Although some features are similar to successful ATDEs in other countries, unique characteristics (e.g., not prioritizing athletes\' autonomy) specific to this ATDE within the Chinese cultural context have been identified. Our findings supplement current studies on ATDEs using the HEA and reflect the environment within Chinese context, offering insights for researchers and practitioners.

    高等教育机构中性别和性别多样化的工作人员可能会在包容性环境中体验到归属感和接受感,但也可能面临歧视和偏见,导致孤立和排斥的感觉。本文报告了与HEI和LGBTQIA盟友中的LGBTQIA自我识别的员工进行的40次深入访谈和6次焦点小组讨论的结果,这些人可能自己认为是LGBTQIA。研究结果表明,以工作人员身份加入大学时的第一印象可能会产生持久的影响,积极和消极的经验都存在。Further,在男同性恋者中形成了一种模式,他们可能更加重视与直线经理的关系,这可能是支持性的,但有时是有毒的,不支持和不专心。除此之外,调查结果突显了员工面临的歧视,它对他们福祉的影响,以及可见性和代表性的意义。本文得出的结论是,LGBTQIA+高等教育工作人员的生活经历继续与经历歧视的工作人员比例很高,主要以微攻击的形式,但是机构需要更加积极主动,以更具包容性的政策和做法为所有人营造安全的空间。
    Sexually and gender diverse staff in Higher Education Institutions may experience a sense of belonging and acceptance in inclusive environments, but may also face discrimination and bias, leading to feelings of isolation and exclusion. This paper reports on findings from 40 in-depth interviews and six focus group discussions with LGBTQIA+ self-identified staff members in a HEI and LGBTQIA+ allies who may identify as LGBTQIA+ themselves. Findings reveal that first impressions when joining a university as a staff member may have a long-lasting effect, while both positive and negative experiences are present. Further, a pattern is developed among gay men who may be placing more emphasis on their relationship with line managers, which can be supportive but at times toxic, unsupportive and inattentive. In addition to this, the findings highlight discrimination faced by staff, its impact on their wellbeing, and the significance of visibility and representation. This paper concludes that lived experiences of LGBTQIA+ staff members in Higher Education continue to be mixed with a high percentage of staff experiencing discrimination, primarily in the form of microaggressions, but institutions need to be more pro-active to foster safe spaces for all with more inclusive policies and practices.

    家族性卵磷脂:胆固醇酰基转移酶(LCAT)缺乏症(FLD)是一种非常罕见的常染色体隐性疾病,其特征是HDL-C水平非常低,角膜混浊,贫血,和进行性肾脏疾病。FLD患者肾脏疾病的发生率和严重程度各不相同,疾病进展的生物标志物和危险因素知之甚少。在这里,我们报告了一项为期30年的临床和实验室生物标志物的比较分析,在FLD患者中,进行了2次肾脏和1次肝脏移植。结果表明,升高的TG和non-HDL-C水平可能促进LpX的形成,加速肾功能下降,而贫血的标志物可能是早期预测因子。相反,角膜混浊以稳定的速率进展,与脂质无关,血液学,或肾脏生物标志物。我们的研究表明,监测贫血标志物可能有助于保守治疗早期发现和及时治疗肾脏疾病。此外,提示控制高胆固醇血症和高甘油三酯血症可能有助于改善肾脏疾病的预后.
    Familial lecithin:cholesterol acyltransferase (LCAT) deficiency (FLD) is an ultra-rare autosomal recessive disease characterized by very low HDL-C levels, corneal opacity, anemia, and progressive renal disease. The rate and severity of renal disease are variable across FLD patients and the biomarkers and risk factors for disease progression are poorly understood. Here we report a 30 year-long comparative analysis of the clinical and laboratory biomarkers in an FLD patient with accelerated renal decline, who underwent 2 kidney and one liver transplantations. Results show that elevated TG and non-HDL-C levels may promote the formation of LpX and accelerate renal function decline, whereas markers of anemia may be early predictors. Conversely, corneal opacity progresses at a steady rate and does not correlate with lipid, hematologic, or renal biomarkers. Our study suggests that monitoring of markers of anemia may aid the early detection and timely management of kidney disease with conservative therapies. Furthermore, it suggests that controlling hypercholesterolemia and hypertriglyceridemia may help improve renal disease prognosis.
