    背景:1/2级PanNET的管理大多类似,通常没有任何辅助治疗,相信他们的整体转移率很低。在肿瘤学文献中,10%的Ki67指数越来越多地用作将患者分层为不同方案的截止值,尽管没有系统的病理学研究支持这种方法。
    方法:Ki67指数与190例切除的PanNETs的临床病理参数相关。单独分析验证队列(n=145)。
    结果:在初始队列中,最大选择的等级统计方法显示,有12%是判别截止值(接近10%的经验法则)。G2b病例的肝/远处转移率比G2a高几乎三倍,并且显示出所有侵袭性组织病理学征象的频率显着升高(肿瘤大小,神经周/血管侵犯,渗透生长模式,淋巴结转移)。在验证队列中,这些数字同样惊人。当所有病例一起分析时,与G1相比,G2b类别的肝/远处转移率高9倍(6.1vs.58.5%;p<0.001)和三倍的淋巴结转移率(20.5vs.65.1%;p<0.001)。
    结论:G2bPanNETs的作用与G3非常相似,支持将其视为潜在候选治疗的管理方案。关于地方管理,G2b病例的转移行为表明它们可能不适合保守方法,如观察等待或摘除。这分时应考虑到诊断指南,和临床试验需要设计,以确定更适合G2b(10%至≤20%)组的管理方案,在超过一半的病例中显示肝脏/远处转移,这至少需要更密切的跟进。
    BACKGROUND: Grade 1/2 PanNETs are mostly managed similarly, typically without any adjunct treatment with the belief that their overall metastasis rate is low. In oncology literature, Ki67-index of 10% is increasingly being used as the cutoff in stratifying patients to different protocols, although there are no systematic pathology-based studies supporting this approach.
    METHODS: Ki67-index was correlated with clinicopathologic parameters in 190 resected PanNETs. A validation cohort (n = 145) was separately analyzed.
    RESULTS: In initial cohort, maximally selected rank statistics method revealed 12% to be the discriminatory cutoff (close to 10% rule of thumb). G2b cases had liver/distant metastasis rate of almost threefold higher than that of G2a and showed significantly higher frequency of all histopathologic signs of aggressiveness (tumor size, perineural/vascular invasion, infiltrative growth pattern, lymph node metastasis). In validation cohort, these figures were as striking. When all cases were analyzed together, compared with G1, the G2b category had nine times higher liver/distant metastasis rate (6.1 vs. 58.5%; p < 0.001) and three times higher lymph node metastasis rate (20.5 vs. 65.1%; p < 0.001).
    CONCLUSIONS: G2b PanNETs act very similar to G3, supporting management protocols that regard them as potential therapy candidates. Concerning local management, metastatic behavior in G2b cases indicate they may not be as amenable for conservative approaches, such as watchful waiting or enucleation. This substaging should be considered into diagnostic guidelines, and clinical trials need to be devised to determine the more appropriate management protocols for G2b (10% to ≤ 20%) group, which shows liver/distant metastasis in more than half of the cases, which at minimum warrants closer follow-up.

    失眠,作为启动和维持睡眠的困难,再加上心血管疾病(CVDs)增加加重白天症状的风险,死亡率,和发病率。认知行为疗法(CBT)被认为对失眠的治疗有显著影响,但是在心血管疾病患者中,数据很少。综合评价CBT对心血管疾病患者失眠治疗的影响。我们搜查了奥维德,Scopus,WebofScience,和科克伦中央,从开始到2022年11月的随机对照试验(RCT)。感兴趣的结果是失眠严重程度指数(ISI),匹兹堡睡眠质量指数(PSQI)睡眠效率(SE),关于睡眠量表(DBAS)的功能失调信念和态度,和睡眠障碍问卷(SDQ)。在使用STATA17forMac的随机效应模型中,使用均值差异(MD)及其95%置信区间(CI)分析汇总数据。包括365名患者的9个RCTs被纳入分析。CBT显着降低了ISI的得分(MD=-3.22,95%CI-4.46至-1.98,p<0.001),PSQI(MD=-2.33,95%CI-3.23至-1.44,p<0.001),DBAS(MD=-0.94,95%CI-1.3至-0.58,p<0.001),SDQ(MD=-0.38,95%CI-0.56至-0.2,p<0.001)。此外,它增加了SE评分(MD=6.65,95%CI2.54至10.77,p<0.001)。然而,在ESS方面没有差异。CBT是一种简单可行的干预措施,可显著改善失眠症状。需要进一步的大量研究来评估持续疗效。
    Insomnia, as a difficulty in initiating and maintaining sleep, coupled with cardiovascular diseases (CVDs) increase the risk of aggravate daytime symptoms, mortality, and morbidity. Cognitive behavioral therapy (CBT) is thought to have a significant impact on insomnia treatment, but in patients with CVDs, there is a paucity of data. To provide a comprehensive appraisal on the impact of CBT on the treatment of insomnia in patients with CVDs. We searched Ovid, Scopus, Web of science, and Cochrane central, to randomized controlled trials (RCTs) from inception till November 2022. Outcomes of interest were insomnia severity index (ISI), Pittsburgh Sleep Quality Index (PSQI), sleep efficiency (SE), Dysfunctional Beliefs and Attitudes about Sleep Scale (DBAS), and sleep disorders questionnaire (SDQ). Pooled data were analyzed using mean difference (MD) with its 95% confidence interval (CI) in a random effect model using STATA 17 for Mac. Nine RCTs comprising 365 patients were included in the analysis. CBT significantly reduced scores of ISI (MD =  - 3.22, 95%  CI - 4.46 to - 1.98, p < 0.001), PSQI (MD =  - 2.33, 95%  CI - 3.23 to - 1.44, p < 0.001), DBAS (MD =  - 0.94, 95%  CI - 1.3 to - 0.58, p < 0.001), SDQ (MD =  - 0.38, 95%  CI - 0.56 to - 0.2, p < 0.001). Also, it increased the score of SE (MD = 6.65, 95% CI 2.54 to 10.77, p < 0.001). However, there was no difference in terms of ESS. CBT is an easy and feasible intervention with clinically significant improvement in insomnia symptoms. Further large-volume studies are needed to assess sustained efficacy.

    背景:口腔疾病是全球主要的公共卫生问题,影响受影响者的生活质量。虽然对高质量的重要性存在共识,循证指南,为医学实践和公共卫生决策提供信息,口腔健康指南的生产者通常不遵守适当的方法和标准。本研究旨在系统地确定在全球范围内制定口腔健康循证指南的组织,并调查制定建议所遵循的方法学过程。
    方法:我们搜索了许多电子数据库,指南库,和指南开发者的网站,科学社会,和国际组织(2012年1月至2023年10月),以确定制定针对任何口腔健康主题的指南并明确宣布在其制定中纳入研究证据的组织。成对的评审员根据预定义的选择标准和提取的有关组织特征的数据,独立评估潜在合格的组织,他们指南的关键特征,以及在制定正式建议时遵循的过程。描述性统计用于分析和总结数据。
    结果:我们纳入了46个制定口腔健康循证指南的组织。这些组织主要是专业协会和科学学会(67%),其次是政府组织(28%)。总的来说,组织制作了55种不同的指导方针文件类型,其中大多数包含临床实践建议(77%)。小组主要由医疗保健专业人员(87%)组成,其次是研究方法学家(40%),决策者(24%),和患者伴侣(18%)。大多数(60%)的指南报告了他们的资金来源,但只有三分之一(33%)包括利益冲突(COI)政策管理。55种准则文件中使用的方法因组织而异,但只有19个(35%)包含正式建议。一半(51%)的准则文件提到了方法论手册,46%的人建议采用结构化的方法或系统来评估证据的确定性和建议的强度,37%的人提到使用框架从证据转向决策,GRADE-EtD是使用最广泛的(27%)。
    结论:我们的发现强调了口腔健康指南中使用的术语和方法与当前国际标准的一致性和标准化的必要性,以制定值得信赖的建议。
    BACKGROUND: Oral diseases are a major global public health problem, impacting the quality of life of those affected. While consensus exists on the importance of high-quality, evidence-informed guidelines to inform practice and public health decisions in medicine, appropriate methodologies and standards are not commonly adhered to among producers of oral health guidelines. This study aimed to systematically identify organizations that develop evidence-informed guidelines in oral health globally and survey the methodological process followed to formulate recommendations.
    METHODS: We searched numerous electronic databases, guideline repositories, and websites of guideline developers, scientific societies, and international organizations (January 2012-October 2023) to identify organizations that develop guidelines addressing any oral health topic and that explicitly declare the inclusion of research evidence in their development. Pairs of reviewers independently evaluated potentially eligible organizations according to predefined selection criteria and extracted data about the organization\'s characteristics, key features of their guidelines, and the process followed when formulating formal recommendations. Descriptive statistics were used to analyze and summarize data.
    RESULTS: We included 46 organizations that developed evidence-informed guidelines in oral health. The organizations were mainly professional associations and scientific societies (67%), followed by governmental organizations (28%). In total, organizations produced 55 different guideline document types, most of them containing recommendations for clinical practice (77%). Panels were primarily composed of healthcare professionals (87%), followed by research methodologists (40%), policymakers (24%), and patient partners (18%). Most (60%) of the guidelines reported their funding source, but only one out of three (33%) included a conflict of interest (COI) policy management. The methodology used in the 55 guideline document types varied across the organizations, but only 19 (35%) contained formal recommendations. Half (51%) of the guideline documents referred to a methodology handbook, 46% suggested a structured approach or system for rating the certainty of the evidence and the strength of recommendations, and 37% mentioned using a framework to move from evidence to decisions, with the GRADE-EtD being the most widely used (27%).
    CONCLUSIONS: Our findings underscore the need for alignment and standardization of both terminology and methodologies used in oral health guidelines with current international standards to formulate trustworthy recommendations.

    这项研究描述了一种对胶质瘤病理切片进行分级的新方法。我们自己的集成高光谱成像系统用于表征来自神经胶质瘤微阵列载玻片的270条带癌组织样本。然后根据世界卫生组织制定的指南对这些样本进行分类,定义了弥漫性神经胶质瘤的亚型和等级。我们使用不同恶性等级的脑胶质瘤的显微高光谱图像探索了一种称为SMLMER-ResNet的高光谱特征提取模型。该模型结合通道注意机制和多尺度图像特征,自动学习胶质瘤的病理组织,获得分层特征表示,有效去除冗余信息的干扰。它还完成了多模态,多尺度空间谱特征提取提高胶质瘤亚型的自动分类。所提出的分类方法具有较高的平均分类精度(>97.3%)和Kappa系数(0.954),表明其在提高高光谱胶质瘤自动分类方面的有效性。该方法很容易适用于广泛的临床环境。为减轻临床病理学家的工作量提供宝贵的帮助。此外,这项研究有助于制定更个性化和更精细的治疗计划,以及随后的随访和治疗调整,通过为医生提供对神经胶质瘤潜在病理组织的见解。
    This study describes a novel method for grading pathological sections of gliomas. Our own integrated hyperspectral imaging system was employed to characterize 270 bands of cancerous tissue samples from microarray slides of gliomas. These samples were then classified according to the guidelines developed by the World Health Organization, which define the subtypes and grades of diffuse gliomas. We explored a hyperspectral feature extraction model called SMLMER-ResNet using microscopic hyperspectral images of brain gliomas of different malignancy grades. The model combines the channel attention mechanism and multi-scale image features to automatically learn the pathological organization of gliomas and obtain hierarchical feature representations, effectively removing the interference of redundant information. It also completes multi-modal, multi-scale spatial-spectral feature extraction to improve the automatic classification of glioma subtypes. The proposed classification method demonstrated high average classification accuracy (>97.3%) and a Kappa coefficient (0.954), indicating its effectiveness in improving the automatic classification of hyperspectral gliomas. The method is readily applicable in a wide range of clinical settings, offering valuable assistance in alleviating the workload of clinical pathologists. Furthermore, the study contributes to the development of more personalized and refined treatment plans, as well as subsequent follow-up and treatment adjustment, by providing physicians with insights into the underlying pathological organization of gliomas.

    背景:尽管体育锻炼(PA)与显着的健康益处相关,只有一小部分青少年达到建议的PA水平.这篇系统综述用荟萃分析探讨了青少年基于设备的PA和/或久坐行为(SB)的可修改决定因素,在以前的干预措施中进行了评估,并检查了PA/SB与这些决定因素之间的关联。
    方法:对五个电子数据库进行了搜索,包括2010年1月至2023年7月发表的论文。随机对照试验(RCT)或对照试验(CT)至少在两个时间点测量青少年基于设备的PA/SB及其可修改的决定因素:干预前和干预后被认为是合格的。PA/SB和决定因素是主要结果。在采用社会生态观点进行数据提取后,对可修改的决定因素进行了分类。根据每个研究设置进行稳健贝叶斯荟萃分析(RoBMA)。仅在一项研究中确定的结果以叙述方式呈现。评估每个研究的偏倚风险和每个荟萃分析的证据的确定性。还检查了发表偏倚。
    CRD42021282874。
    结果:14项RCT(学校有8项,三个在学校和家庭,包括一个在家庭环境中)和一个CT(在学校环境中)。确定了54个可修改的决定因素,并将其合并为33个更广泛的决定因素(21个个体心理学,四种个人行为,七个人际关系,和一个机构)。在所有设置中,ROBMA对PA/SB或决定因素没有或可忽略的合并干预作用。干预措施对结果影响的证据的确定性从非常低到低。叙事,在学校环境中检测到有利于实验组的干预效果的决定因素:实践PA的环境知识,d=1.84,95CI(1.48,2.20),行为改变技术,d=0.90,95CI(0.09,1.70),提供的选择,d=0.70,95CI(0.36,1.03),但未发现对PA或SB的相应影响。
    结论:发现了关于已确定的可修改决定因素与青少年基于设备的PA/SB之间关联的证据,可能是由于干预无效。精心设计和实施良好的多组分干预措施应进一步探索各种可修改的青少年决定因素\'PA/SB,包括政策和环境变量。
    BACKGROUND: Although physical activity (PA) is associated with significant health benefits, only a small percentage of adolescents meet recommended PA levels. This systematic review with meta-analysis explored the modifiable determinants of adolescents\' device-based PA and/or sedentary behaviour (SB), evaluated in previous interventions and examined the associations between PA/SB and these determinants in settings.
    METHODS: A search was conducted on five electronic databases, including papers published from January 2010 to July 2023. Randomized Controlled Trials (RCTs) or Controlled Trials (CTs) measuring adolescents\' device-based PA/SB and their modifiable determinants at least at two time points: pre- and post-intervention were considered eligible. PA/SB and determinants were the main outcomes. Modifiable determinants were classified after data extraction adopting the social-ecological perspective. Robust Bayesian meta-analyses (RoBMA) were performed per each study setting. Outcomes identified in only one study were presented narratively. The risk of bias for each study and the certainty of the evidence for each meta-analysis were evaluated. The publication bias was also checked.
    UNASSIGNED: CRD42021282874.
    RESULTS: Fourteen RCTs (eight in school, three in school and family, and one in the family setting) and one CT (in the school setting) were included. Fifty-four modifiable determinants were identified and were combined into 33 broader determinants (21 individual-psychological, four individual-behavioural, seven interpersonal, and one institutional). RoBMAs revealed none or negligible pooled intervention effects on PA/SB or determinants in all settings. The certainty of the evidence of the impact of interventions on outcomes ranged from very low to low. Narratively, intervention effects in favour of the experimental group were detected in school setting for the determinants: knowledge of the environment for practicing PA, d = 1.84, 95%CI (1.48, 2.20), behaviour change techniques, d = 0.90, 95%CI (0.09, 1.70), choice provided, d = 0.70, 95%CI (0.36, 1.03), but no corresponding effects on PA or SB were found.
    CONCLUSIONS: Weak to minimal evidence regarding the associations between the identified modifiable determinants and adolescents\' device-based PA/SB in settings were found, probably due to intervention ineffectiveness. Well-designed and well-implemented multicomponent interventions should further explore the variety of modifiable determinants of adolescents\' PA/SB, including policy and environmental variables.

    OBJECTIVE: To describe the methodology used by the Reassessment Campaign on Veterinary Resuscitation (RECOVER) to re-evaluate the scientific evidence relevant to CPR in small and large animals, to newborn resuscitation, and to first aid and to formulate the respective consensus-based clinical guidelines.
    METHODS: This report describes the evidence-to-guidelines process employed by RECOVER that is based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach and includes Information Specialist-driven systematic literature search, evidence evaluation conducted by more than 200 veterinary professionals, and provision of clinical guidelines in the domains of Preparedness and Prevention, Basic Life Support, Advanced Life Support, Post-cardiac Arrest Care, Newborn Resuscitation, First Aid, and Large Animal CPR.
    METHODS: Transdisciplinary, international collaboration in academia, referral practice, and general practice.
    RESULTS: For this update to the RECOVER 2012 CPR guidelines, we answered 135 Population, Intervention, Comparator, and Outcome (PICO) questions with the help of a team of Domain Chairs, Information Specialists, and more than 200 Evidence Evaluators. Most primary contributors were veterinary specialists or veterinary technician specialists. The RECOVER 2024 Guidelines represent the first veterinary application of the GRADE approach to clinical guideline development. We employed an iterative process that follows a predefined sequence of steps designed to reduce bias of Evidence Evaluators and to increase the repeatability of the quality of evidence assessments and ultimately the treatment recommendations. The process also allowed numerous important knowledge gaps to emerge that form the foundation for prioritizing research efforts in veterinary resuscitation science.
    CONCLUSIONS: Large collaborative, volunteer-based development of evidence- and consensus-based clinical guidelines is challenging and complex but feasible. The experience gained will help refine the process for future veterinary guidelines initiatives.

    UNASSIGNED: Autism is a neurodevelopmental condition that is increasing in prevalence worldwide. There has been an exponential increase in autism-related research since 2010, when the first Singapore Clinical Practice Guidelines (CPG) on autism was published. Understanding of autism has since evolved to adopt a lifespan approach beyond that of a childhood condition. The aim of this CPG was to provide an updated set of recommendations for children and adolescents to aid clinical practice for professionals.
    UNASSIGNED: A multidisciplinary workgroup that comprised representatives from various sectors worked on this CPG. Clinical questions were organised into 10 different sections, each with its own subgroup of members. Seventeen existing international guidelines were evaluated using the Appraisal of Guidelines for REsearch & Evaluation II (AGREE-II) framework, of which 4 met criteria to act as references. Literature review across multiple databases was conducted between January 2011 to 2023; Grading of Recommendations, Assessment, Development and Evaluation (GRADE-like) methodology was used to synthesise evidence. Recommendation statements were derived, following Delphi-style consensus surveys among the workgroup. The draft guidelines underwent external review and public consultation before being formalised.
    UNASSIGNED: Recommendation and good practice statements pertaining to care of children and adolescents on the autism spectrum across 10 different sections were developed. Evidence matrices complement these recommendations and detail relevant evidence behind each recommendation statement.
    UNASSIGNED: It is intended for these guidelines to promote effective management and healthcare services for children and adolescents on the autism spectrum, by reinforcing good and evidence-based clinical practice within our national context.
