    肌萎缩侧索硬化症(ALS)是一种普遍致命的神经退行性疾病,无法治愈。人内源性逆转录病毒(HERV)已涉及其发病机理,但其与ALS的相关性尚未完全了解。我们检查了来自近2,000个ALS和来自皮质和脊髓的不受影响的对照样品的大量RNA-seq数据。使用不同的特征选择方法,包括差异表达分析和机器学习,我们发现HERV-K位点1q22和8p23.1的转录在ALS患者的脊髓中显著上调.此外,我们确定了ALS患者的一个亚组在皮质和脊髓HERV-K表达上调.在这项研究中,我们还发现HERV-K基因座19q11和8p23.1的表达与先前与ALS有关的蛋白质编码基因相关,并且在ALS患者中失调。这些结果阐明了HERV-K和ALS的关联,并突出了晚期ALS病理生物学中的特定基因。
    Amyotrophic lateral sclerosis (ALS) is a universally fatal neurodegenerative disease with no cure. Human endogenous retroviruses (HERVs) have been implicated in its pathogenesis but their relevance to ALS is not fully understood. We examined bulk RNA-seq data from almost 2,000 ALS and unaffected control samples derived from the cortex and spinal cord. Using different methods of feature selection, including differential expression analysis and machine learning, we discovered that transcription of HERV-K loci 1q22 and 8p23.1 were significantly upregulated in the spinal cord of individuals with ALS. Additionally, we identified a subset of ALS patients with upregulated HERV-K expression in the cortex and spinal cord. We also found the expression of HERV-K loci 19q11 and 8p23.1 was correlated with protein coding genes previously implicated in ALS and dysregulated in ALS patients in this study. These results clarify the association of HERV-K and ALS and highlight specific genes in the pathobiology of late-stage ALS.

    目标:奥地利的公立医学大学(教育11,000名学生)开发了一个联合的公共远程学习系列,其中临床医生讨论了他们专业的当前数字灯塔项目。本研究旨在研究讲座系列前后参与者的态度和知识的变化,以获得对未来课程发展的见解。
    方法:系列讲座通过各种渠道在大学中宣布,在健康通讯和社交媒体中。在系列讲座之前和之后,对医学数字化的态度进行了调查,以及人口统计数据。对四组感兴趣的学生:女医学生,男性医学生,来自行业和公共机构的教师和成员。
    结果:在参加至少1次讲座的351名受试者中,117人参加了讲座前的调查,47人参加了讲座后的调查。大多数参与者对数字化持积极态度(85.3%)。他们对知识的自我评估从34.4%提高到64.7%(p<0.05)。在讲座系列之后,55.8%的参与者认为数字医疗应用在今天很重要或非常重要,68.6%的参与者认为数字医疗应用在未来很重要。
    结论:研究表明,对灯塔项目的介绍和讨论提高了对医学数字化的理解,但并未引发对进一步培训的强烈渴望。
    OBJECTIVE: The public medical universities in Austria (educating 11,000 students) developed a joint public distance learning series in which clinicians discussed current digital lighthouse projects in their specialty. This study aims to examine the changes in attitude and knowledge of the participants before and after the lecture series to gain insights for future curriculum developments.
    METHODS: The lecture series was announced via various channels at the universities, in health newsletters and in social media. Attitudes toward digitalization in medicine were surveyed before and after the lecture series, together with demographic data. The data were analyzed statistically and descriptively for four groups of interest: female medical students, male medical students, faculty members and members from industry and public agencies.
    RESULTS: Out of 351 subjects who attended at least 1 lecture, 117 took part in the survey before and 47 after the lectures. Most participants had a positive attitude towards digitalization (85.3%). They improved their self-assessment of their knowledge from 34.4% to 64.7% (p < 0.05). After the lecture series 55.8% of participants considered digital medical applications to be important or very important today and 68.6% in the future.
    CONCLUSIONS: The study shows that the presentation and discussion of lighthouse projects improves understanding of digitalization in medicine but does not trigger a strong desire for additional further training.

    背景:有语言障碍的患者遇到医疗保健差异,这可以通过利用口译员技能来减少文化,语言,和识字障碍,通过改善双向交流。证据支持使用现场口译员,特别是涉及复杂护理需求的患者的互动。不幸的是,由于口译员短缺和临床医生对口译员的使用不足,有语言障碍的病人往往得不到他们需要或有权得到的语言服务。卫生信息技术(HIT),包括人工智能(AI),有可能简化流程,提示临床医生使用现场口译员,和支持优先级。
    方法:从2023年5月1日至2024年6月21日,一项单中心阶梯式楔形整群随机试验将在罗切斯特梅奥诊所圣玛丽医院和卫理公会医院的35个单位内进行。明尼苏达。这些单位包括医疗,外科,创伤,以及混合的ICU和医院楼层,可容纳急性内科和外科护理患者以及急诊科(ED)。研究阶段之间的过渡将以60天的间隔开始,导致12个月的研究期。对照组的单位将接受标准护理,并依靠临床医生主动要求口译服务。在干预组中,研究小组将每天生成一份有语言障碍的成年住院患者名单,根据其复杂性分数(从最高到最低)对列表进行排序,并与口译员服务分享,谁会向床边护士发送安全聊天消息。这种参与将由基于姑息治疗评分的预测性机器学习算法触发,辅以其他复杂性预测因素,包括住院时间和护理水平以及程序,事件,和临床笔记。
    结论:这种务实的临床试验方法将把预测性机器学习算法集成到工作流程中,并评估干预的有效性。我们将比较对照组和干预组之间亲自口译员的使用情况和首次使用口译员的时间。
    背景:NCT05860777。2023年5月16日。
    BACKGROUND: Patients with language barriers encounter healthcare disparities, which may be alleviated by leveraging interpreter skills to reduce cultural, language, and literacy barriers through improved bidirectional communication. Evidence supports the use of in-person interpreters, especially for interactions involving patients with complex care needs. Unfortunately, due to interpreter shortages and clinician underuse of interpreters, patients with language barriers frequently do not get the language services they need or are entitled to. Health information technologies (HIT), including artificial intelligence (AI), have the potential to streamline processes, prompt clinicians to utilize in-person interpreters, and support prioritization.
    METHODS: From May 1, 2023, to June 21, 2024, a single-center stepped wedge cluster randomized trial will be conducted within 35 units of Saint Marys Hospital & Methodist Hospital at Mayo Clinic in Rochester, Minnesota. The units include medical, surgical, trauma, and mixed ICUs and hospital floors that admit acute medical and surgical care patients as well as the emergency department (ED). The transitions between study phases will be initiated at 60-day intervals resulting in a 12-month study period. Units in the control group will receive standard care and rely on clinician initiative to request interpreter services. In the intervention group, the study team will generate a daily list of adult inpatients with language barriers, order the list based on their complexity scores (from highest to lowest), and share it with interpreter services, who will send a secure chat message to the bedside nurse. This engagement will be triggered by a predictive machine-learning algorithm based on a palliative care score, supplemented by other predictors of complexity including length of stay and level of care as well as procedures, events, and clinical notes.
    CONCLUSIONS: This pragmatic clinical trial approach will integrate a predictive machine-learning algorithm into a workflow process and evaluate the effectiveness of the intervention. We will compare the use of in-person interpreters and time to first interpreter use between the control and intervention groups.
    BACKGROUND: NCT05860777. May 16, 2023.

    肾衰竭在美国尤其常见,它影响了超过70万人。通常通过反复进行血液透析来过滤和清洁血液。血液透析需要血管通路,在大约70%的病例中,通过连接动脉和静脉手术产生的动静脉瘘(AVF)。AVF需要6周或更长时间才能成熟。成熟的瘘管通常需要干预,最常见的经皮经腔血管成形术(PTA),也被称为瘘管成形术,维持瘘管的通畅.PTA也是恢复血流和延长AVF使用的一线干预措施,许多患者多次接受手术。虽然PTA对于AVF的成熟和维持很重要,对PTA后AVF功能预测模型的研究一直很有限。因此,在本文中,我们假设基于在PTA期间收集的患者特定信息,可以创建预测模型以帮助改进治疗计划。我们测试了一套富人,来自28名患者的多模式数据,包括病史,AVF血流,和介入血管造影成像(特别是不包括任何PTA后测量),并建立深度混合神经网络。建立了3D卷积神经网络与多层感知器相结合的混合模型对AVF进行分类。我们发现使用该模型,我们能够识别不同因素之间的关联,并评估PTA程序是否可以维持主要通畅超过3个月。获得的测试准确度为0.75,加权F1评分为0.75,AUROC为0.75。这些结果表明,使用人工神经网络评估多模式临床数据可以预测PTA的结果。这些初步发现表明,结合临床数据的混合模型,影像学和血流动力学分析可用于血液透析的治疗计划。需要基于大型队列的进一步研究来完善准确性和模型效率。
    Kidney failure is particularly common in the United States, where it affects over 700,000 individuals. It is typically treated through repeated sessions of hemodialysis to filter and clean the blood. Hemodialysis requires vascular access, in about 70% of cases through an arteriovenous fistula (AVF) surgically created by connecting an artery and vein. AVF take 6 weeks or more to mature. Mature fistulae often require intervention, most often percutaneous transluminal angioplasty (PTA), also known as fistulaplasty, to maintain the patency of the fistula. PTA is also the first-line intervention to restore blood flow and prolong the use of an AVF, and many patients undergo the procedure multiple times. Although PTA is important for AVF maturation and maintenance, research into predictive models of AVF function following PTA has been limited. Therefore, in this paper we hypothesize that based on patient-specific information collected during PTA, a predictive model can be created to help improve treatment planning. We test a set of rich, multimodal data from 28 patients that includes medical history, AVF blood flow, and interventional angiographic imaging (specifically excluding any post-PTA measurements) and build deep hybrid neural networks. A hybrid model combining a 3D convolutional neural network with a multi-layer perceptron to classify AVF was established. We found using this model that we were able to identify the association between different factors and evaluate whether the PTA procedure can maintain primary patency for more than 3 months. The testing accuracy achieved was 0.75 with a weighted F1-score of 0.75, and AUROC of 0.75. These results indicate that evaluating multimodal clinical data using artificial neural networks can predict the outcome of PTA. These initial findings suggest that the hybrid model combining clinical data, imaging and hemodynamic analysis can be useful to treatment planning for hemodialysis. Further study based on a large cohort is needed to refine the accuracy and model efficiency.

    背景:COVID-19大流行对急性冠状动脉综合征(ACS)患者的护理质量和临床结局的有害影响,因此需要在大流行环境下对预后预测模型进行严格的重新评估。本研究旨在阐明大流行期间ACS患者30天死亡率预测模型的适应性。
    方法:纳入了2020年12月至2023年4月期间来自32个机构的2041例连续ACS患者。数据集包括因ACS入院并在住院期间接受冠状动脉造影诊断的患者。全球急性冠状动脉事件注册(GRACE)和机器学习模型的预测准确性,KOTOMI,对ST段抬高型急性心肌梗死(STEMI)和非ST段抬高型急性冠脉综合征(NSTE-ACS)患者的30天死亡率进行了评估.
    结果:STEMI的受试者工作特征曲线下面积(AUROC)在GRACE中为0.85(95%CI0.81至0.89),在KOTOMI中为0.87(95%CI0.82至0.91)。0.020(95%CI-0.098-0.13)差异不显著。对于NSTE-ACS,GRACE中各自的AUROC为0.82(95%CI0.73至0.91),KOTOMI中的AUROC为0.83(95%CI0.74至0.91),也显示差异不显著0.010(95%CI-0.023至0.25)。两种模型的预测准确性在STEMI患者中具有一致性,而在大流行期之间,NSTE-ACS患者的差异不大。
    结论:即使在大流行时期,预测模型也能保持ACS患者30天死亡率的高准确性。尽管观察到边际变化。
    BACKGROUND: The detrimental repercussions of the COVID-19 pandemic on the quality of care and clinical outcomes for patients with acute coronary syndrome (ACS) necessitate a rigorous re-evaluation of prognostic prediction models in the context of the pandemic environment. This study aimed to elucidate the adaptability of prediction models for 30-day mortality in patients with ACS during the pandemic periods.
    METHODS: A total of 2041 consecutive patients with ACS were included from 32 institutions between December 2020 and April 2023. The dataset comprised patients who were admitted for ACS and underwent coronary angiography for the diagnosis during hospitalisation. The prediction accuracy of the Global Registry of Acute Coronary Events (GRACE) and a machine learning model, KOTOMI, was evaluated for 30-day mortality in patients with ST-elevation acute myocardial infarction (STEMI) and non-ST-elevation acute coronary syndrome (NSTE-ACS).
    RESULTS: The area under the receiver operating characteristics curve (AUROC) was 0.85 (95% CI 0.81 to 0.89) in the GRACE and 0.87 (95% CI 0.82 to 0.91) in the KOTOMI for STEMI. The difference of 0.020 (95% CI -0.098-0.13) was not significant. For NSTE-ACS, the respective AUROCs were 0.82 (95% CI 0.73 to 0.91) in the GRACE and 0.83 (95% CI 0.74 to 0.91) in the KOTOMI, also demonstrating insignificant difference of 0.010 (95% CI -0.023 to 0.25). The prediction accuracy of both models had consistency in patients with STEMI and insignificant variation in patients with NSTE-ACS between the pandemic periods.
    CONCLUSIONS: The prediction models maintained high accuracy for 30-day mortality of patients with ACS even in the pandemic periods, despite marginal variation observed.

    背景:急诊科拥挤继续威胁患者的安全并导致患者预后不良。先前设计用于预测住院的模型存在偏见。成功估计患者入院概率的预测模型将有助于减少或预防急诊科“登机”和医院“出口障碍”,并通过提前入院和避免旷日持久的床位采购流程来减少急诊科的拥挤。
    目的:通过利用现有的临床描述符,开发一种模型来预测即将从急诊科住院的成年患者在患者就诊早期(即,患者生物标志物)在分诊时常规收集并记录在医院的电子病历中。生物标志物有利于建模,因为它们在分诊时的早期和常规收集;瞬时可用性;标准化定义,测量,和解释;以及他们摆脱患者病史的限制(即,他们不会受到不准确的病史患者报告的影响,不可用的报告,或延迟报告检索)。
    方法:这项回顾性队列研究评估了急诊科成年患者1年的连续数据事件,并开发了一种算法来预测哪些患者需要即将入院。评估了八个预测变量在患者急诊科就诊结果中的作用。采用Logistic回归对研究数据进行建模。
    结果:8预测模型包括以下生物标志物:年龄,收缩压,舒张压,心率,呼吸频率,温度,性别,和敏锐度水平。该模型使用这些生物标志物来识别需要住院的急诊科患者。我们的模型表现很好,观察到的和预测的录取之间有很好的一致性,这表明了一个很好的拟合和校准良好的模型,显示出很好的能力来区分谁会入院和不会入院。
    结论:这个基于主要数据的预测模型确定了急诊科患者入院风险增加。这些可操作的信息可用于改善患者护理和医院运营,特别是通过预测分诊后哪些患者可能入院,从而减少急诊科的拥挤,从而提供所需的信息,以在护理连续体中更早地启动复杂的入院和床位分配过程。
    BACKGROUND: Emergency department crowding continues to threaten patient safety and cause poor patient outcomes. Prior models designed to predict hospital admission have had biases. Predictive models that successfully estimate the probability of patient hospital admission would be useful in reducing or preventing emergency department \"boarding\" and hospital \"exit block\" and would reduce emergency department crowding by initiating earlier hospital admission and avoiding protracted bed procurement processes.
    OBJECTIVE: To develop a model to predict imminent adult patient hospital admission from the emergency department early in the patient visit by utilizing existing clinical descriptors (ie, patient biomarkers) that are routinely collected at triage and captured in the hospital\'s electronic medical records. Biomarkers are advantageous for modeling due to their early and routine collection at triage; instantaneous availability; standardized definition, measurement, and interpretation; and their freedom from the confines of patient histories (ie, they are not affected by inaccurate patient reports on medical history, unavailable reports, or delayed report retrieval).
    METHODS: This retrospective cohort study evaluated 1 year of consecutive data events among adult patients admitted to the emergency department and developed an algorithm that predicted which patients would require imminent hospital admission. Eight predictor variables were evaluated for their roles in the outcome of the patient emergency department visit. Logistic regression was used to model the study data.
    RESULTS: The 8-predictor model included the following biomarkers: age, systolic blood pressure, diastolic blood pressure, heart rate, respiration rate, temperature, gender, and acuity level. The model used these biomarkers to identify emergency department patients who required hospital admission. Our model performed well, with good agreement between observed and predicted admissions, indicating a well-fitting and well-calibrated model that showed good ability to discriminate between patients who would and would not be admitted.
    CONCLUSIONS: This prediction model based on primary data identified emergency department patients with an increased risk of hospital admission. This actionable information can be used to improve patient care and hospital operations, especially by reducing emergency department crowding by looking ahead to predict which patients are likely to be admitted following triage, thereby providing needed information to initiate the complex admission and bed assignment processes much earlier in the care continuum.

    BACKGROUND: Governments and public health agencies worldwide experienced difficulties with social media-mediated infodemics on the internet during the COVID-19 pandemic. Existing public health crisis communication strategies need to be updated. However, crisis communication experiences of governments and public health agencies worldwide during the COVID-19 pandemic have not been systematically compiled, necessitating updated crisis communication strategies.
    OBJECTIVE: This systematic review aims to collect and organize the crisis communication experiences of senders (ie, governments and public health agencies) during the COVID-19 pandemic. Our focus is on exploring the difficulties that governments and public health agencies experienced, best practices in crisis communication by governments and public health agencies during the COVID-19 pandemic in times of infodemic, and challenges that should be overcome in future public health crises.
    METHODS: We plan to begin the literature search on May 1, 2024. We will search PubMed, MEDLINE, CINAHL, PsycINFO, PsycARTICLES, Communication Abstracts, and Web of Science. We will filter our database searches to search from the year 2020 and beyond. We will use a combination of keywords by referring to the SPIDER (Sample, Phenomenon of Interest, Design, Evaluation, and Research type) tool to search the abstracts in databases. We intend to include qualitative studies on crisis communication by governments and public health agencies (eg, officials, staff, health professionals, and researchers) to the public. Quantitative data-based studies will be excluded. Only papers written in English will be included. Data on study characteristics, study aim, participant characteristics, methodology, theoretical framework, object of crisis communication, and key results will be extracted. The methodological quality of eligible studies will be assessed using the Joanna Briggs Institute critical appraisal checklist for qualitative research. A total of 2 independent reviewers will share responsibility for screening publications, data extraction, and quality assessment. Disagreement will be resolved through discussion, and the third reviewer will be consulted, if necessary. The findings will be summarized in a table and a conceptual diagram and synthesized in a descriptive and narrative review.
    RESULTS: The results will be systematically integrated and presented in a way that corresponds to our research objectives and interests. We expect the results of this review to be submitted for publication by the end of 2024.
    CONCLUSIONS: To our knowledge, this will be the first systematic review of the experiences of governments and public health agencies regarding their crisis communication to the public during the COVID-19 pandemic. This review will contribute to the future improvement of the guidelines for crisis communication by governments and public health agencies to the public.

    背景:远程皮肤病学和会诊中的模糊图像增加了深度学习模型和医生的诊断难度。我们的目标是确定模糊图像通过深度学习模型进行模糊处理后诊断准确性的恢复程度。方法:我们使用了公共皮肤图像数据集中的19,191张皮肤图像,其中包括23种皮肤病类别,来自模糊皮肤图像的公开数据集中的54张皮肤图像,和医疗中心的53张模糊皮肤科会诊照片,比较训练后的诊断深度学习模型的诊断准确率和模糊图像与去模糊图像之间的主观清晰度。我们评估了五种不同的去模糊模型,包括运动模糊模型,高斯模糊,博克·模糊,混合轻微模糊,混合强烈的模糊。主要结果和措施:诊断准确性被测量为皮肤疾病类别的正确模型预测的灵敏度和精度。锐度等级由董事会认证的皮肤科医生以4分制进行,4是最高的图像清晰度。结果:在轻微和强烈模糊的图像上,诊断模型的灵敏度下降了0.15和0.22,分别,去模糊模型每组恢复0.14和0.17。去模糊后,皮肤科医生认为的清晰度等级从1.87提高到2.51。激活图显示诊断模型的焦点因模糊而受到损害,但在去模糊后得以恢复。结论:深度学习模型可以恢复模糊图像诊断模型的诊断准确性,并提高皮肤科医生感知的图像清晰度。该模型可以并入皮肤学,以帮助模糊图像的诊断。
    Background: Blurry images in teledermatology and consultation increased the diagnostic difficulty for both deep learning models and physicians. We aim to determine the extent of restoration in diagnostic accuracy after blurry images are deblurred by deep learning models. Methods: We used 19,191 skin images from a public skin image dataset that includes 23 skin disease categories, 54 skin images from a public dataset of blurry skin images, and 53 blurry dermatology consultation photos in a medical center to compare the diagnosis accuracy of trained diagnostic deep learning models and subjective sharpness between blurry and deblurred images. We evaluated five different deblurring models, including models for motion blur, Gaussian blur, Bokeh blur, mixed slight blur, and mixed strong blur. Main Outcomes and Measures: Diagnostic accuracy was measured as sensitivity and precision of correct model prediction of the skin disease category. Sharpness rating was performed by board-certified dermatologists on a 4-point scale, with 4 being the highest image clarity. Results: The sensitivity of diagnostic models dropped 0.15 and 0.22 on slightly and strongly blurred images, respectively, and deblurring models restored 0.14 and 0.17 for each group. The sharpness ratings perceived by dermatologists improved from 1.87 to 2.51 after deblurring. Activation maps showed the focus of diagnostic models was compromised by the blurriness but was restored after deblurring. Conclusions: Deep learning models can restore the diagnostic accuracy of diagnostic models for blurry images and increase image sharpness perceived by dermatologists. The model can be incorporated into teledermatology to help the diagnosis of blurry images.
