    甲状腺切除术相对安全,通常可以作为微创手术进行。尽管它们可能与学习曲线有关,术中附件如能量装置的周到使用,喉返神经监测,和甲状旁腺自发荧光有可能在甲状腺手术的安全性和效率方面取得递增的改善.也许许多这些附件可能是最大的好处,当常规使用经验较少的外科医生或有选择地在高风险的手术,尽管它们在实践中的采用率总体上继续增加。
    Thyroidectomy is relatively safe and often can be done as a minimally invasive procedure. Although they may be associated with a learning curve, thoughtful use of intraoperative adjuncts such as energy devices, recurrent laryngeal nerve monitoring, and parathyroid autofluorescence have the potential to make incremental improvements in the safety and efficiency of thyroid surgery. Perhaps many of these adjuncts may be of greatest benefit when used routinely by less experienced surgeons or selectively in higher-risk operations, although their adoption in practice continues to increase overall.

    胶质瘤是神经外科医生解决的最典型的脑肿瘤之一。在神经胶质瘤脑肿瘤手术的导航过程中,术前采集的静态图像可能由于移位而不准确。外科医生使用术中成像技术(二维和导航三维超声)来评估和指导切除。本文旨在精确捕获术前参数的重要性,以决定将哪种类型的超声用于特定手术。
    本文提出了两种考虑基分类器逻辑回归和随机森林的套袋算法。在原始数据集的不同子集上训练这些算法。使用假设检验建立了基于Logistic回归的装袋算法的拟合优度。此外,使用的基于随机森林的装袋算法的性能度量是ROC下的AUC和精度-召回曲线下的AUC。我们还提出了一个复合模型,而不损害模型的可解释性。
    这些模型是根据2015年至2020年接受脑部手术的350名患者的数据进行训练的。假设检验表明,单个参数就足够了,而不是与肿瘤相关的所有三个维度([公式:见正文])。我们观察到术中超声的选择取决于外科医生的选择,多年的外科医生经验可以替代这种依赖。
    这项研究表明,神经外科医生可能不需要关注大量的术前参数来决定超声检查。此外,它在手术中个性化使用特定的超声选项。这种方法可能会导致更好的资源管理,并帮助医疗机构改善决策,使手术更有效。
    Gliomas are among the most typical brain tumors tackled by neurosurgeons. During navigation for surgery of glioma brain tumors, preoperatively acquired static images may not be accurate due to shifts. Surgeons use intraoperative imaging technologies (2-Dimensional and navigated 3-Dimensional ultrasound) to assess and guide resections. This paper aims to precisely capture the importance of preoperative parameters to decide which type of ultrasound to be used for a particular surgery.
    This paper proposes two bagging algorithms considering base classifier logistic regression and random forest. These algorithms are trained on different subsets of the original data set. The goodness of fit of Logistic regression-based bagging algorithms is established using hypothesis testing. Furthermore, the performance measures for random-forest-based bagging algorithms used are AUC under ROC and AUC under the precision-recall curve. We also present a composite model without compromising the explainability of the models.
    These models were trained on the data of 350 patients who have undergone brain surgery from 2015 to 2020. The hypothesis test shows that a single parameter is sufficient instead of all three dimensions related to the tumor ([Formula: see text]). We observed that the choice of intraoperative ultrasound depends on the surgeon making a choice, and years of experience of the surgeon could be a surrogate for this dependence.
    This study suggests that neurosurgeons may not need to focus on a large set of preoperative parameters in order to decide on ultrasound. Moreover, it personalizes the use of a particular ultrasound option in surgery. This approach could potentially lead to better resource management and help healthcare institutions improve their decisions to make the surgery more effective.

    包括手术切除在内的多模态疗法是目前治疗恶性胸膜间皮瘤(MPM)的范例,无法治愈的胸表面癌。所有手术方法的主要限制是缺乏长期耐久性,因为宏观完全切除(R1切除)通常容易局部复发。多年来,有许多研究描述了旨在扩大手术切除效果的各种胸膜内治疗策略.这些方法中的大多数是术中佐剂。广义上,有三个治疗类采用不同的药物。最常见的,广泛使用的佐剂组由直接治疗如腔内化疗(±热疗)组成。相比之下,最不常用的胸腔内佐剂是由药物-装置组合如光动力疗法(PDT)组成的类别。但是,具有改善功效潜力的最迅速发展的(新)类别是通过专门的药物载体(例如含有顺铂的纤维蛋白凝胶)递送的治疗剂。这篇综述提供了关于MPM管理中胸膜定向辅助手段的最新观点,并强调了最有前途的近期技术突破。
    Multimodality therapy including surgical resection is the current paradigm in treating malignant pleural mesothelioma (MPM), a thoracic surface cancer without cure. The main limitation of all surgical approaches is the lack of long-term durability because macroscopic complete resection (R1 resection) commonly predisposes to locoregional relapse. Over the years, there have been many studies that describe various intrapleural strategies that aim to extend the effect of surgical resection. The majority of these approaches are intraoperative adjuvants. Broadly, there are three therapeutic classes that employ diverse agents. The most common, widely used group of adjuvants are comprised of direct therapeutics such as intracavitary chemotherapy (± hyperthermia). By comparison, the least commonly employed intrathoracic adjuvant is the class comprised of drug-device combinations like photodynamic therapy (PDT). But the most rapidly evolving (new) class with much potential for improved efficacy are therapeutics delivered by specialized drug vehicles such as a fibrin gel containing cisplatin. This review provides an updated perspective on pleural-directed adjuncts in the management of MPM as well as highlighting the most promising near-term technology breakthroughs.

    OBJECTIVE: Focused parathyroidectomy has been proven to be a safe technique for the treatment of single-gland primary hyperparathyroidism (PHPT). The CaPTHUS scoring model has been reported to be an accurate preoperative diagnostic tool for distinguishing single-gland (SGD) from multiglandular disease (MGD), including preoperative serum calcium and PTH values plus ultrasound and Sestamibi scanning. The purpose of the present study was to validate the CaPTHUS model for the population in southern Europe, since the North American and the European populations show different clinicopathological profiles in PHPT.
    METHODS: This is a retrospective review of a prospectively maintained database of patients diagnosed with PHPT who underwent surgical treatment in a single referral center. Differences between SGD and MGD groups were analyzed using chi-square and Fisher\'s exact tests for categorical variables and Student\'s t test for continuous variables. Overall diagnostic accuracy of the scoring model was assessed by the area under the receiver operating characteristic (ROC) curve (AUC). A p < 0.05 level was accepted as significant.
    RESULTS: From January 2001 to November 2014, 241 patients were included in the study, of whom 92.1 % had SGD and 71.8 % had a CaPTHUS score ≥3. SGD was distinguished from MGD (p < 0.001) using the dichotomous scoring model based on an AUC value of 0.762. Scores ≥3 had a sensitivity of 76.5 % and a positive predictive value of 96 % for SGD.
    CONCLUSIONS: Despite good test performance, a CaPTHUS score ≥3 does not discard MGD definitely. Intraoperative adjuncts are still needed to further reduce the risk of missing MGD during selective parathyroidectomy.

    OBJECTIVE: Knowledge about compliance with recommendations derived from the positional statement of the European Society of Endocrine Surgeons on modern techniques in primary hyperparathyroidism surgery and the Third International Workshop on management of asymptomatic primary hyperparathyroidism is scarce. Our purpose was to check it on a bi-national basis and determine whether management differences may have impact on surgical outcomes.
    METHODS: An online survey including questions about indications, preoperative workup, surgical approach, intraoperative adjuncts, and outcomes was sent to institutions affiliated to the endocrine surgery divisions of the National Surgical Societies from Spain and Portugal. A descriptive evaluation of the responses was performed. Finally, we assessed the correlation between the different types of management with the achievement of optimal results, defined as a cure rate equal or greater than the median of all interviewed institutions.
    RESULTS: Fifty-seven hospitals (41 Spanish, 16 Portuguese) answered the survey. First-ordered imaging tests were neck ultrasound and sestamibi scan. Facing negative or non-concordant results, 44 % of surgeons ordered additional tests before first-time surgery, and 84 % before reoperations. When indicated, selective parathyroidectomy was an acceptable option for 95 % of institutions as first-time surgery and for 51 % in reoperations. Intraoperative parathormone measurements were used by 92 % of departments. The surgical outcomes were good in most institutions (median cure rate 97 %) and were influenced mostly by the presence of an endocrine surgery unit in the surgical department (p = 0.038).
    CONCLUSIONS: Practice of Iberian endocrine surgeons is consistent with current recommendations on surgery for primary hyperparathyroidism, with variability in some areas.
