    在应用于考古和古生态学研究的植物学领域,这项研究的多学科和跨学科性质导致缺乏数据共享和分散的文章在专业文献或国家和国际期刊。古植物学和孢粉学数据的大量生产使得有必要开发一种可用性工具,可访问性,和现有研究的传播。有许多关于古生态学的数据库,古植物学或花粉数据。没有集中在考古遗址和人为环境上的收藏,并且集中在南欧和地中海。大脑-考古植物学记录意大利网络是第一个数据库,列出了意大利和附近地中海地区所有类型的植物记录。BRAIN代表了最大的古细菌/古植物学数据集成集合,以及一系列使数据恢复FAIR准备就绪的描述性信息。这个独特的网络承载着关于人为花粉可用性的数据,palynorphs和植物宏观遗骸在同一个数据库中,不同研究领域的专家可能对此有所贡献。
    In the field of botany applied to archaeological and palaeoecological studies, the multi- and inter-disciplinary nature of this research produces a lack of data sharing and scattered articles in the specialty literature or in national and international journals. The vast production of archaeobotany and palynology data makes it necessary to develop a tool for the availability, accessibility, and dissemination of existing research. Many databases exist on palaeoecology, archaeobotany or pollen data. There are no collections focused on archaeological sites and human-induced environments and centred on Southern Europe and the Mediterranean. BRAIN - Botanical Records of Archaeobotany Italian Network is the first database listing sites from which all types of plant records are available in Italy and nearby Mediterranean regions. BRAIN represents the largest integrated collection of archaeo/palaeo-botanical data and a range of descriptive information that makes data recovery FAIR ready. This unique network hosts data on the availability of anthropogenic pollen, palynomorphs and plant macroremains in the same database, and experts of different research fields may contribute to it.

    目的:与肺切除术相比,在胸外科手术中,气道手术相对罕见。尽管如此,越来越多的专用气道中心已经在整个欧洲形成。这些中心的特点是密切的跨学科合作,它们通常充当超区域推荐中心。迄今为止,气道手术的大部分证据来自回顾性研究,由于缺乏大规模的单中心分析,多机构数据库。
    方法:2018年,一项倡议成立,它旨在在ESTS数据库(AIR-ESTS)的框架内创建气道数据库。五个专门的气道中心被要求在试验阶段测试数据库。对AIR-ESTS进行了第一次描述性分析。
    结果:共415例纳入分析。对于成年人来说,最常见的气道手术指征是气管造口术后狭窄和特发性声门下狭窄;在儿童中,大多数切除/重建必须针对插管后狭窄进行.与良性适应症(26.6(9.4-43.8)mm)相比,恶性适应症需要更长的切除时间(36.0(21.4-50.6)mm)。住院时间为11.0(4.1-17.3)天(成人)和13.4(7.6-19.6)天(儿童)。总的来说,并发症发生率较低,据报道伤口感染是最常见的发病率.
    结论:对AIR-ESTS数据库中首例病例的评估允许对欧洲专用气道中心的气道手术实践进行大规模分析。它为AIR-ESTS的功能提供了证据,并为将AIR小节推广到参与ESTS数据库的所有中心奠定了基础。
    OBJECTIVE: Compared to lung resections, airway procedures are relatively rare in thoracic surgery. Despite this, a growing number of dedicated airway centres have formed throughout Europe. These centres are characterized by a close interdisciplinary collaboration and they often act as supra-regional referring centres. To date, most evidence of airway surgery comes from retrospective, single-centre analysis as there is a lack of large-scale, multi-institutional databases.
    METHODS: In 2018, an initiative was formed, which aimed to create an airway database within the framework of the ESTS database (ESTS-AIR). Five dedicated airway centres were asked to test the database in a pilot phase. A 1st descriptive analysis of ESTS-AIR was performed.
    RESULTS: A total of 415 cases were included in the analysis. For adults, the most common indication for airway surgery was post-tracheostomy stenosis and idiopathic subglottic stenosis; in children, most resections/reconstructions had to be performed for post-intubation stenosis. Malignant indications required significantly longer resections [36.0 (21.4-50.6) mm] when compared to benign indications [26.6 (9.4-43.8) mm]. Length of hospital stay was 11.0 (4.1-17.3) days (adults) and 13.4 (7.6-19.6) days (children). Overall, the rates of complications were low with wound infections being reported as the most common morbidity.
    CONCLUSIONS: This evaluation of the 1st cases in the ESTS-AIR database allowed a large-scale analysis of the practice of airway surgery in dedicated European airway centres. It provides proof for the functionality of ESTS-AIR and sets the basis for rolling out the AIR subsection to all centres participating in the ESTS database.

    背景:由于区分模棱两可的痣的主观性,诊断侵袭性皮肤黑色素瘤(CM)可能具有挑战性,黑色素瘤原位和薄CMs从痣进展为黑色素瘤的潜在分子机制必须得到更好的理解。确定治疗反应的生物标志物,诊断和预后至关重要。使用来自生物库的生物医学数据和基于人群的医疗保健数据,转化研究可以通过实施循证研究来改善患者护理。BioMEL生物银行是一个潜在的,多中心,关于模棱两可的痣和原发性黑色素瘤转移的所有阶段的大规模生物医学数据库。它的目的是作为翻译资源,使研究人员能够发现客观分子,基因型,痣和黑色素瘤所有阶段的表型和结构差异。主要目标是利用BioMEL显着改善诊断,黑色素瘤患者的预后和治疗结果。
    方法:BioMEL生物样本库包含生物样本,接受黑色素瘤常规治疗的成年患者的流行病学信息和医学数据。BioMEL专注于原发性和转移性黑色素瘤,但也包括不明确的色素性病变,如临床上非典型痣和原位黑色素瘤。BioMEL数据是通过问卷调查收集的,采血,肿瘤成像,组织取样,病历和组织病理学报告。
    背景:BioMEL生物库项目已获得瑞典国家道德审查局(Dnr。2013/101、2013/339、2020/00469、2021/01432和2022/02421-02)。由于与伦理审查机构相关的规定,生成的数据集不可公开。
    背景:NCT05446155。
    Diagnosing invasive cutaneous melanoma (CM) can be challenging due to subjectivity in distinguishing equivocal nevi, melanoma in situ and thin CMs. The underlying molecular mechanisms of progression from nevus to melanoma must be better understood. Identifying biomarkers for treatment response, diagnostics and prognostics is crucial. Using biomedical data from biobanks and population-based healthcare data, translational research can improve patient care by implementing evidence-based findings. The BioMEL biobank is a prospective, multicentre, large-scale biomedical database on equivocal nevi and all stages of primary melanoma to metastases. Its purpose is to serve as a translational resource, enabling researchers to uncover objective molecular, genotypic, phenotypic and structural differences in nevi and all stages of melanoma. The main objective is to leverage BioMEL to significantly improve diagnostics, prognostics and therapy outcomes of patients with melanoma.
    The BioMEL biobank contains biological samples, epidemiological information and medical data from adult patients who receive routine care for melanoma. BioMEL is focused on primary and metastatic melanoma, but equivocal pigmented lesions such as clinically atypical nevi and melanoma in situ are also included. BioMEL data are gathered by questionnaires, blood sampling, tumour imaging, tissue sampling, medical records and histopathological reports.
    The BioMEL biobank project is approved by the national Swedish Ethical Review Authority (Dnr. 2013/101, 2013/339, 2020/00469, 2021/01432 and 2022/02421-02). The datasets generated are not publicly available due to regulations related to the ethical review authority.
    NCT05446155.

    比较干预措施的安全性和有效性的方法包括分析来自随机对照试验(RCT)的数据,登记册和观察数据库(ODB)。RCT被认为是黄金标准,但这些试验的数据有时无法获得,因为疾病并不常见,因为干预并不常见,由于结构限制或由于实际或(看似)道德原因无法进行随机化。有许多例子表明,未经证实的干预措施被广泛认为是有效的,以至于临床测试人员和潜在受试者拒绝随机化。通常,当RCT最终完成时,干预被证明无效甚至有害.这些情况被称为医疗逆转,并不少见[1,2]。当看似相似的RCT报告来自高质量注册管理机构的不和谐数据时,也存在两难境地,特别是当来自RCT的数据不可用但也有限制时,可以使用ODB。偏差和混杂协变量可能是未知的,难以或不可能识别和/或难以充分调整。然而,ODB有时具有大量不同的受试者,并且通常比RCT提供对临床医生更有用的答案。并排比较表明,来自高质量ODB的分析通常会从高质量RCT中得出类似的结论。结合RCT数据的荟萃分析,注册管理机构和ODB有时是合适的。我们建议增加使用注册表和ODB来比较干预措施的疗效。
    Approaches to comparing safety and efficacy of interventions include analyzing data from randomized controlled trials (RCTs), registries and observational databases (ODBs). RCTs are regarded as the gold standard but data from such trials are sometimes unavailable because a disease is uncommon, because the intervention is uncommon, because of structural limitations or because randomization cannot be done for practical or (seemingly) ethical reasons. There are many examples of an unproved intervention being so widely-believed to be effective that clinical trialists and potential subjects decline randomization. Often, when a RCT is finally done the intervention is proved ineffective or even harmful. These situations are termed medical reversals and are not uncommon [1,2]. There is also the dilemma of when seemingly similar RCTs report discordant conclisions Data from high-quality registries, especially ODBs can be used when data from RCTs are unavailable but also have limitations. Biases and confounding co-variates may be unknown, difficult or impossible to identify and/or difficult to adjust for adequately. However, ODBs sometimes have large numbers of diverse subjects and often give answers more useful to clinicians than RCTs. Side-by-side comparisons suggest analyses from high-quality ODBs often give similar conclusions from high quality RCTs. Meta-analyses combining data from RCTs, registries and ODBs are sometimes appropriate. We suggest increased use of registries and ODBs to compare efficacy of interventions.

    免疫检查点抑制剂正在成为晚期胃肠道癌症越来越常见的治疗方法。但免疫相关不良事件的可能性引起了人们的关注.这项研究旨在评估接受免疫检查点抑制剂的患者与接受不同类型胃肠道癌症化疗的患者之间免疫相关不良事件的风险。该研究利用了美国多中心TriNetX数据库的数据,涵盖了2015年至2022年之间的时间。危险比和95%置信区间被用来描述免疫相关不良事件的相对危险基于比较的时间-事件率。我们的研究表明,接受免疫检查点抑制剂和化疗的患者的免疫相关不良事件发生率明显高于仅接受化疗的患者。与PD-1/PD-L1抑制剂相比,CTLA-4抑制剂倾向于具有更高的免疫相关不良事件发生率。我们的研究发现,与倾向评分匹配后未发生免疫相关不良事件的患者相比,发生免疫相关不良事件的患者的死亡率较低(HR,0.661;95%CI0.620-0.704;p<0.01)。我们提供了有关使用免疫检查点抑制剂治疗的晚期胃肠道癌症患者中免疫相关不良事件的发生率和影响的重要现实数据。我们的研究结果支持临床医生就免疫检查点抑制剂治疗胃肠道癌症患者的潜在益处和风险做出明智的决定。
    Immune checkpoint inhibitors are becoming an increasingly common treatment for advanced gastrointestinal cancer, but the possibility of immune-related adverse events has raised concerns. This study aimed to evaluate the risks of immune-related adverse events between patients who received immune checkpoint inhibitors and those who received chemotherapy among different types of gastrointestinal cancer. The study utilized data from the multicenter TriNetX database in the United States covering the period between 2015 and 2022. Hazard ratios and 95% confidence intervals were used to describe the relative hazard of immune-related adverse events based on comparing time-to-event rates. Our study revealed that the incidence of immune-related adverse events was significantly higher in patients who received immune checkpoint inhibitors and chemotherapy compared to those who received chemotherapy only in treating gastrointestinal cancer. CTLA-4 inhibitors tended to have a higher rate of immune-related adverse events compared to PD-1/PD-L1 inhibitors. Our study found a lower mortality rate among patients who developed immune-related adverse events compared to those who did not after propensity score matching (HR, 0.661; 95% CI 0.620-0.704; p < .01). We provide important real-world data on the incidence and impact of immune-related adverse events in patients with advanced gastrointestinal cancer treated with immune checkpoint inhibitors. Our study\'s results support clinicians in making informed decisions about the potential benefits and risks of immune checkpoint inhibitor therapy for patients with gastrointestinal cancer.

    营养不良在心力衰竭(HF)患者中普遍存在,增加功能下降的可能性。我们评估了血红蛋白-老年营养风险指数(H-GNRI)结合血红蛋白和老年营养风险指数(GNRI)对老年HF患者预后的预测价值。我们使用JMDC多中心数据库来检查营养不良风险与其他结局指标之间的潜在关联。患者被归类为低(H-GNRI评分=0),中间-(H-GNRI分数=1),或高风险(H-GNRI评分=2)基于他们的H-GNRI评分。主要结果指标是Barthel指数(BI)增益;次要结果包括出院时的BI,BI效率,住院时间,住院死亡率,出院回家或疗养院,和住院相关的残疾。我们分析了3532名患者,244是低风险的,952是中等风险,2336人是高危病人.高危患者组出院时BI值明显降低,较低的BI收益,降低了BI效率值,与低风险组相比,住院时间延长。高危患者的住院死亡率也较高,家庭或疗养院的出院率较低,与低危组相比,住院相关残疾的发生率更高。H-GNRI可作为确定HF患者预后的有价值的工具。
    Malnutrition prevails among patients with heart failure (HF), increasing the likelihood of functional decline. We assessed the predictive value of the Hemoglobin-Geriatric Nutritional Risk Index (H-GNRI)-combining hemoglobin and the Geriatric Nutritional Risk Index (GNRI)-on prognosis in older patients with HF. We used the JMDC multicenter database to examine the potential associations between malnutrition risk and other outcome measures. The patients were categorized as low- (H-GNRI score = 0), intermediate- (H-GNRI score = 1), or high-risk (H-GNRI score = 2) based on their H-GNRI scores. The primary outcome measure was the Barthel Index (BI) gain; the secondary outcomes included the BI at discharge, the BI efficiency, length of hospital stay, in-hospital mortality, discharge to home or a nursing home, and hospitalization-associated disability. We analyzed 3532 patients, with 244 being low-risk, 952 being intermediate-risk, and 2336 being high-risk patients. The high-risk group of patients had significantly lower BI values at discharge, lower BI gains, reduced BI efficiency values, and prolonged hospital stays compared to those in the low-risk group. The high-risk patients also had higher in-hospital mortality rates, lower rates of discharge to home or a nursing home, and greater incidences of a hospitalization-associated disability in comparison to the low-risk group. The H-GNRI may serve as a valuable tool for determining prognoses for patients with HF.

    目的:描述创建多中心人工耳蜗数据库作为未来医疗数据库设计的模板。检查的第一个临床问题是BMI与人工耳蜗植入手术时间和术后结果之间的关系。
    方法:REDCap中的回顾性存储库,命名为“耳蜗植入信息库”(ROCII),创建并收集了接受人工耳蜗植入的患者的去识别数据。将数据导出并分层为三个BMI分组(<25,25.0-29.9,≥30.0)。使用混合效应模型分析手术时间和AZBioSentenceTest术后评分变化的差异。
    结果:平均BMI(n=145)为28.52,平均手术时间为128.9分钟。BMI<25参考组(n=50)和BMI25.0-29.9组(n=50)的平均手术时间相同,为127.5分钟。BMI≥30.0组(n=45)的平均手术时间为132分钟,然而,与参考组相比,这一差异无统计学意义(p=0.4727).AZBio术后平均评分变化(n=74)为63.32。BMI<25参考组(n=29)的术后平均变化为56.66。BMI25.0-29.9组(n=22)和BMI≥30.0组(n=23)的平均术后变化分别为61.32和73.65。然而,与参考组相比,这些差异无统计学意义(p=0.5847,0.0637).
    结论:BMI与手术时间或术后结局无显著关联,因此不应成为植入的禁忌症。ROCII将有助于更深入地了解评估过程,结果,以及跨机构人工耳蜗植入的患者体验。
    方法:1级。
    OBJECTIVE: To describe the creation of a multi-center cochlear implant database as a template for future medical database design. The first clinical question examined was the association between BMI on cochlear implant surgical time and postoperative outcome.
    METHODS: A retrospective repository in REDCap, named the \"Repository of Cochlear Implant Information\" (ROCII), was created and collected de-identified data on patients who underwent cochlear implantation. Data was exported and stratified into three BMI groupings (<25, 25.0-29.9, ≥ 30.0). Differences in surgical time and AZBio Sentence Test postoperative score changes were analyzed using the mixed-effect model.
    RESULTS: The mean BMI (n = 145) was 28.52, and the mean surgical time was 128.9 min. The BMI < 25 reference group (n = 50) and the BMI 25.0-29.9 group (n = 50) had an identical mean surgical time of 127.5 min. The BMI ≥30.0 group (n = 45) had a mean surgical time of 132 min, however this difference was not statistically significant when compared to the reference group (p = 0.4727). The mean AZBio postoperative score change (n = 74) was 63.32. The BMI < 25 reference group (n = 29) had a mean postoperative change of 56.66. The BMI 25.0-29.9 group (n = 22) and BMI ≥30.0 group (n = 23) had mean postoperative changes of 61.32 and 73.65 respectively, however these differences were not statistically significant compared to the reference group (p = 0.5847, 0.0637).
    CONCLUSIONS: BMI did not have a significant association with surgical time or postoperative outcome and therefore should not be a contraindication for implantation. ROCII will facilitate a deeper understanding of the evaluation process, outcomes, and patient experience of cochlear implantation across institutions.
    METHODS: Level 1.
