    动脉瘤样骨囊肿是良性的,最常见的非肿瘤性病变影响骨。在某些情况下报告了恶性转化,虽然罕见。它通常发生在年轻人中,大约75%的病例发生在前二十年,95%发生在前三十年。管理取决于个体病例参数,ABC发生在骨骼的负重区域,保证积极的治疗计划,同时考虑预防病理性骨折。
    一名20岁男性患者,没有其他合并症,向我们介绍了9个月的非创伤性右髋部疼痛。在X射线的初步临床检查和影像学研究中,CT扫描,MRI,患者被诊断为右股骨近端动脉瘤样骨囊肿(ABC)。该患者接受了病灶内切除术,并进行了长期刮治和DHS钢板预防性固定,并每年进行一次随访。10年的随访显示病变完全消退,然后进行植入物移除。
    从这种情况可以清楚地看出,动脉瘤样骨囊肿的治疗需要根据患者的年龄进行个体化,投诉,和肿瘤的侵袭性,尺寸,和它的程度。通常,需要进行全面刮除的整块切除以及植骨和预防性固定,以支持植骨并防止病理性骨折和进一步复发。如果需要,应在病变完全消退后进行植入物切除,患者意愿,和任何其他医学适应症。
    UNASSIGNED: Aneurysmal bone cyst is a benign, most often non-neoplastic lesion affecting the bone. Malignant transformation is reported in certain cases, although rare. It commonly occurs in young adults with around 75% of the cases occurring in the first two decades and 95% occurring in the first 3 decades. The management depends on the individual case parameters with ABC occurring in a weight-bearing area of a bone warranting an aggressive treatment plan with the consideration of preventing a pathological fracture.
    UNASSIGNED: A 20-year-old male patient with no other comorbidities presented to us with complaints of atraumatic right hip pain of 9-month duration. On preliminary clinical examination and imaging studies with X-rays, CT scan, and MRI, the patient was diagnosed to have an aneurysmal bone cyst (ABC) of the right proximal femur. The patient was operated with intra-lesional excision with extended curettage and prophylactic fixation with DHS plating and kept on yearly follow-up. 10-year follow-up showed complete resolution of the lesion and implant removal was done after that.
    UNASSIGNED: As is clear from this case, the treatment of an aneurysmal bone cyst needs to individualized based on the patient\'s age, complaints, and tumor behavior in terms of its aggressiveness, size, and its extent. Often, en bloc excision with extensive curettage is required along with bone grafting and prophylactic fixation to support the bone graft and to prevent a pathological fracture and further recurrence. Implant removal if indicated should be done after complete resolution of the lesion, patient willingness, and any other medical indication.

    本研究旨在从父母的角度探讨奥尔夫音乐疗法对自闭症谱系障碍(ASD)儿童的临床效果,评价者,和治疗师。
    93名年龄在3-6岁的ASD儿童参加了这项研究。将其分为观察组(n=48),接受包括奥尔夫音乐疗法在内的综合康复干预,对照组(n=45)仅接受综合康复干预。自闭症行为清单(ABC)儿童自闭症评定量表(CARS),和心理教育概况-第3版(PEP-3)用于干预前后的评估。
    两组之间没有显著的人口统计学差异。两组在感官上都有显著改善,有关,语言,CVP,EL,RL,VMI,AE,SR,以及T1、T2和T3时的CARS评分(T1与T2,T2vs.T3,T1vs.T3)(均p<0.05)。观察组表现出身体和物体使用和FM的显着变化,而对照组在这些领域显示出一些变化。社会和自助,GM,CMB,干预6个月后,两组患者的CVB也有显著改善(均p<0.05)。就不同的时间间隔而言,观察组在感觉方面表现出更大的改善,有关,语言,CARS得分,EL,RL,和SR与对照组相比(均p<0.05)。主体和对象使用的改进级别,CVP,FM,VMI,在T1-T2间期,两组之间的AE没有显着差异,但观察组在T2-T3和T1-T3间期均显著高于对照组(均p<0.05)。社会和自助的变化幅度,GM,CMB,和CVB在两组之间没有显着差异。
    奥尔夫音乐疗法显示出语言表达的显著改善,语言理解,社交技能,认知能力,模仿能力,ASD儿童的情绪表达和精细运动。这些发现为使用奥尔夫音乐疗法作为ASD儿童的有效干预措施提供了支持。
    UNASSIGNED: This study aimed to investigate the clinical effects of Orff music therapy on children with Autism Spectrum Disorder (ASD) from the perspectives of parents, evaluators, and therapists.
    UNASSIGNED: 93 children with ASD aged 3-6 years participated in the study. They were divided into an observation group (n = 48) receiving comprehensive rehabilitation intervention including Orff music therapy, and a control group (n = 45) receiving only comprehensive rehabilitation intervention. The Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS), and Psycho-educational Profile-3rd edition (PEP-3) were used for assessments before and after the intervention.
    UNASSIGNED: There were no significant demographic differences between the two groups. Both groups showed significant improvements in Sensory, Relating, Language, CVP, EL, RL, VMI, AE, SR, and CARS scores at T1, T2, and T3 (T1 vs. T2, T2 vs. T3, T1 vs. T3) (all p < 0.05). The observation group demonstrated significant changes in Body and Object use and FM, while the control group showed some changes in these domains. Social and self-help, GM, CMB, and CVB also significantly improved in both groups after 6 months of intervention (all p < 0.05). In terms of different time intervals, the observation group showed greater improvements in Sensory, Relating, Language, CARS scores, EL, RL, and SR compared to the control group (all p < 0.05). The improvement levels in Body and Object use, CVP, FM, VMI, and AE did not differ significantly between the two groups in the T1-T2 interval, but were significantly higher in the observation group in the T2-T3 and T1-T3 intervals (all p < 0.05). The magnitude of changes in Social and self-help, GM, CMB, and CVB did not differ significantly between the groups.
    UNASSIGNED: Orff music therapy showed significant improvements in language expression, language comprehension, social skills, cognitive abilities, imitation abilities, emotional expression and fine motor in children with ASD. These findings provide support for the use of Orff music therapy as an effective intervention for children with ASD.

    本手稿描述了在最近两次ABC国际共识会议上更新的晚期乳腺癌(ABC)国际共识指南(ABC6于2021年,虚拟,2023年在里斯本的ABC7,葡萄牙),由ABC全球联盟组织。它提供了关于如何最好地管理晚期乳腺癌患者(无法手术的局部晚期或转移性)的主要建议,在所有乳腺癌亚型中,以及姑息治疗和支持治疗。这些指南基于现有证据或缺乏更高水平证据时的专家意见。每个指南都附有证据水平(LoE),推荐等级(GoR)和在共识会议上达成共识的百分比。还提供了更新的诊断和治疗算法。该指南代表了全球ABC患者的最佳管理选择,假设可以使用所有可用的治疗方法。在获得护理的机会有限的环境中,通常需要对其进行调整(即资源分层指南)。
    This manuscript describes the Advanced Breast Cancer (ABC) international consensus guidelines updated at the last two ABC international consensus conferences (ABC 6 in 2021, virtual, and ABC 7 in 2023, in Lisbon, Portugal), organized by the ABC Global Alliance. It provides the main recommendations on how to best manage patients with advanced breast cancer (inoperable locally advanced or metastatic), of all breast cancer subtypes, as well as palliative and supportive care. These guidelines are based on available evidence or on expert opinion when a higher level of evidence is lacking. Each guideline is accompanied by the level of evidence (LoE), grade of recommendation (GoR) and percentage of consensus reached at the consensus conferences. Updated diagnostic and treatment algorithms are also provided. The guidelines represent the best management options for patients living with ABC globally, assuming accessibility to all available therapies. Their adaptation (i.e. resource-stratified guidelines) is often needed in settings where access to care is limited.

    动脉瘤性骨囊肿(ABCs)是罕见的良性骨病变,对长骨干meta端有好感。它们通常是囊性的,膨胀,和溶骨,并可能导致骨畸形。总的来说,关于ABC的最佳治疗仍存在争议;然而,主要由刮宫的组合组成,骨移植,并考虑内固定和截骨术的需要。治疗的目标包括保留骨解剖结构,同时消除病变。关于与良性骨肿瘤相邻的骨关节炎的治疗的文献很少。如果选择全髋关节置换术作为治疗选择,需要勤奋的术前计划,外科医生必须评估病人的骨存量,骨畸形的原因,并根据患者的特征使用特定的植入物和技术。我们介绍了一例患有股骨近端ABC和有症状的相邻髋关节骨关节炎的成年患者,该患者接受了全髋关节置换术的治疗。
    Aneurysmal bone cysts (ABCs) are rare benign bone lesions with a predilection for the metaphysis of long bones. They are often cystic, expansive, and osteolytic and may result in bony deformity. In general, there remains debate about optimal treatment for ABCs; however, the mainstay typically consists of a combination of curettage, bone grafting, and considering the need for internal fixation and osteotomies. The goals of treatment include preserving bony anatomy while eliminating the lesion. There is sparse literature regarding the treatment of osteoarthritis adjacent to benign bony tumors. If total hip arthroplasty is chosen as a treatment option, diligent preoperative planning is required, and the surgeon must assess the patient\'s bone stock, account for bony deformity, and utilize specific implants and techniques based on the patient\'s characteristics. We present a case of an adult patient with proximal femur ABC and symptomatic adjacent hip osteoarthritis who underwent treatment with total hip arthroplasty.

    糖皮质激素已经使用了几十年来治疗淋巴瘤,但没有确定的作用机制。使用功能基因组,蛋白质组学,和化学屏幕,我们发现糖皮质激素抑制B细胞受体(BCR)的致癌信号,侵袭性B细胞恶性肿瘤的复发特征,包括弥漫性大B细胞淋巴瘤和伯基特淋巴瘤。糖皮质激素诱导糖皮质激素受体(GR)直接反式激活编码BCR稳定性(LAPTM5;KLHL14)和PI3激酶途径(INPP5D;DDIT4)的负调节因子的基因。GR直接抑制CSK的转录,一种限制BCR-近端Src-家族激酶活性的激酶。CSK抑制通过过度激活Src家族激酶减弱淋巴瘤的组成型BCR信号,引发它们的泛素化和降解。了解到糖皮质激素禁用致癌BCR信号,它们现在可以合理地用于治疗BCR依赖性侵袭性淋巴瘤,并用于构建与BTK抑制剂的机械合理组合方案,PI3激酶,BCL2和CSK。
    Glucocorticoids have been used for decades to treat lymphomas without an established mechanism of action. Using functional genomic, proteomic, and chemical screens, we discover that glucocorticoids inhibit oncogenic signaling by the B cell receptor (BCR), a recurrent feature of aggressive B cell malignancies, including diffuse large B cell lymphoma and Burkitt lymphoma. Glucocorticoids induce the glucocorticoid receptor (GR) to directly transactivate genes encoding negative regulators of BCR stability (LAPTM5; KLHL14) and the PI3 kinase pathway (INPP5D; DDIT4). GR directly represses transcription of CSK, a kinase that limits the activity of BCR-proximal Src-family kinases. CSK inhibition attenuates the constitutive BCR signaling of lymphomas by hyperactivating Src-family kinases, triggering their ubiquitination and degradation. With the knowledge that glucocorticoids disable oncogenic BCR signaling, they can now be deployed rationally to treat BCR-dependent aggressive lymphomas and used to construct mechanistically sound combination regimens with inhibitors of BTK, PI3 kinase, BCL2, and CSK.

    网络模型越来越多地用于研究传染病传播。指数随机图模型在这方面有历史,现在可以使用可扩展的推理方法。另一种方法使用机械网络模型。机械网络模型直接捕获个体行为,使它们适合研究性传播疾病。将机械模型与近似贝叶斯计算相结合,可以使用代理之间特定领域的交互规则进行灵活的建模,避免网络模型过度简化。这些模型对于纵向设置是理想的,因为它们明确地结合了网络随时间的演变。我们实现了先前发布的连续时间模型的离散时间版本,该模型用于与男性发生性关系的男性不断发展的联系网络,并为此提出了基于ABC的近似推理方案。不出所料,我们发现,与横截面设计相比,两波纵向研究设计提高了推断的准确性。然而,两次收集数据的精度提高,高达18%,取决于两个波的间距,并且对汇总统计的选择很敏感。除了方法的发展,我们的结果为未来性传播疾病纵向网络研究的设计提供了信息,特别是在从参与者那里收集什么数据以及何时收集数据方面。
    Network models are increasingly used to study infectious disease spread. Exponential Random Graph models have a history in this area, with scalable inference methods now available. An alternative approach uses mechanistic network models. Mechanistic network models directly capture individual behaviors, making them suitable for studying sexually transmitted diseases. Combining mechanistic models with Approximate Bayesian Computation allows flexible modeling using domain-specific interaction rules among agents, avoiding network model oversimplifications. These models are ideal for longitudinal settings as they explicitly incorporate network evolution over time. We implemented a discrete-time version of a previously published continuous-time model of evolving contact networks for men who have sex with men and proposed an ABC-based approximate inference scheme for it. As expected, we found that a two-wave longitudinal study design improves the accuracy of inference compared to a cross-sectional design. However, the gains in precision in collecting data twice, up to 18%, depend on the spacing of the two waves and are sensitive to the choice of summary statistics. In addition to methodological developments, our results inform the design of future longitudinal network studies in sexually transmitted diseases, specifically in terms of what data to collect from participants and when to do so.

    在进化过程的大型模型中,参数的统计估计通常在计算上效率低下,无法使用精确的模型似然性来追求。即使使用单核苷酸多态性(SNP)数据,这提供了一种在保留相关信息的同时减少遗传数据大小的方法。执行关于大型模型的参数的统计推断的近似贝叶斯计算(ABC)利用模拟来绕过模型可能性的直接评估。我们开发了一个机械模型来模拟具有可变迁移率的时间前向发散选择,繁殖方式(性,无性),迁移选择周期的长度和数量。我们研究了ABC进行统计推断的计算可行性,并研究了选择中基因座位置的估计质量和选择强度。要展开选择下的位置的参数空间,我们通过对汇总的观测数据实施离群扫描来增强模型。我们评估了众所周知的汇总统计数据对捕捉选择强度的有用性,并在不同的选择下评估它们的信息量。我们还评估了遗传漂移相对于单基因座选择的理想化确定性模型的影响。我们讨论了重组率作为估计发散选择强度的混杂因素的作用,并强调其在打破连锁不平衡(LD)中的重要性。我们回答的问题是,在模型的参数空间的哪一部分中,我们恢复了用于估计选择的强信号,并确定基于人口差异的汇总统计或基于LD的汇总统计在估计选择方面是否表现良好。
    Statistical estimation of parameters in large models of evolutionary processes is often too computationally inefficient to pursue using exact model likelihoods, even with single-nucleotide polymorphism (SNP) data, which offers a way to reduce the size of genetic data while retaining relevant information. Approximate Bayesian Computation (ABC) to perform statistical inference about parameters of large models takes the advantage of simulations to bypass direct evaluation of model likelihoods. We develop a mechanistic model to simulate forward-in-time divergent selection with variable migration rates, modes of reproduction (sexual, asexual), length and number of migration-selection cycles. We investigate the computational feasibility of ABC to perform statistical inference and study the quality of estimates on the position of loci under selection and the strength of selection. To expand the parameter space of positions under selection, we enhance the model by implementing an outlier scan on summarized observed data. We evaluate the usefulness of summary statistics well-known to capture the strength of selection, and assess their informativeness under divergent selection. We also evaluate the effect of genetic drift with respect to an idealized deterministic model with single-locus selection. We discuss the role of the recombination rate as a confounding factor in estimating the strength of divergent selection, and emphasize its importance in break down of linkage disequilibrium (LD). We answer the question for which part of the parameter space of the model we recover strong signal for estimating the selection, and determine whether population differentiation-based summary statistics or LD-based summary statistics perform well in estimating selection.

    背景:中度深吸气屏气(mDIBH)是一种以心脏保留而闻名的方式。基于此的前瞻性研究很少来自世界东部和印度。我们打算比较mDIBH和自由呼吸(FB)计划之间的剂量学。
    方法:研究对象为32例局部晚期左乳癌患者。所有患者接受50Gy的剂量,分为25个部分,以胸壁/完整的乳房,在乳房保护手术的情况下,随后对乳房切除术腔进行10Gy的提升。所有患者均使用主动呼吸协调器(ABC)进行mDIBH治疗。关于计划质量和由有风险的器官接收的剂量,比较来自两个剂量体积直方图的数据。采用配对t检验进行数据分析。
    结果:ABC组的心脏接受V5,V10和V30的剂量(4.55%vs8.39%)和平均剂量(4.73Gyvs6.74Gy)均具有统计学意义。比FB组(所有p值<0.001)。此外,在ABC组中,LADA接受的V30剂量(19.32%vs24.87%)和平均剂量(32.99Gyvs46.65Gy)明显较少.ABC组的平均治疗时间为20分钟,而自由呼吸组为10分钟。
    结论:将ABC-mDIBH纳入左侧乳腺癌放疗可显著降低心脏接受的剂量,LADA,左肺和右肺,计划质量没有妥协,但治疗时间增加。
    BACKGROUND: The moderate deep inspiratory breath hold (mDIBH) is a modality famed for cardiac sparing. Prospective studies based on this are few from the eastern part of the world and India. We intend to compare the dosimetry between mDIBH and free-breathing (FB) plans.
    METHODS: Thirty-two locally advanced left breast cancer patients were taken up for the study. All patients received a dose of 50 Gy in 25 fractions to the chest wall/intact breast, followed by a 10-Gy boost to the lumpectomy cavity in the case of breast conservation surgery. All the patients were treated in mDIBH using active breath coordinator (ABC). The data from the two dose volume histograms were compared regarding plan quality and the doses received by the organs at risk. Paired t-test was used for data analysis.
    RESULTS: The dose received by the heart in terms of V5, V10, and V30 (4.55% vs 8.39%) and mean dose (4.73 Gy vs 6.74 Gy) were statistically significant in the ABC group than that in the FB group (all p-values < 0.001). Also, the dose received by the LADA in terms of V30 (19.32% vs 24.87%) and mean dose (32.99 Gy vs 46.65 Gy) were significantly less in the ABC group. The mean treatment time for the ABC group was 20 min, while that for the free-breathing group was 10 min.
    CONCLUSIONS: Incorporating ABC-mDIBH for left-sided breast cancer radiotherapy significantly reduces the doses received by the heart, LADA, and left and right lung, with no compromise in plan quality but with an increase in treatment time.

    这篇综述的目的是提高对动脉瘤性骨囊肿(ABC)的诊断和治疗的当前趋势的演变和发展的认识。ABC是良性的,但主要影响儿童的局部侵袭性骨肿瘤。ABCs占所有原发性骨肿瘤的1%,在生命的头二十年中最常见。诊断是使用多种成像方式进行的,并且具有膨胀性的特征,放射状病变,常见于骨的干phy端区域,并且在MRI上具有明显的流体水平。在儿科人群中,毛细血管扩张骨肉瘤和单房骨囊肿(UBC)是ABC的主要鉴别诊断。巨细胞瘤(GCT)也包括在鉴别诊断中,这通常表现在15岁以上的患者中,尽管它们在physeal闭合后发展,但不会穿透开放性physis。单靠影像学不能排除毛细血管扩张骨肉瘤;因此,建议进行活检。已经描述了多种治疗方案;传统上,大多数患者接受刮宫和植骨治疗。独自刮宫,然而,切除后通常会导致肿瘤复发。已使用各种佐剂以不同程度的有效性来降低局部复发的风险。当囊肿在骨盆时,它的位置和大小使得手术是一个非常危险的选择。选择性动脉栓塞术极大地促进了针对这些情况的有效治疗方法的发展。栓塞或辐射,以及denosumab疗法,在手术会显着增加发病率的解剖位置,广泛用作ABC的疗法。
    The purpose of this review is to increase awareness about the evolution and development of current trends in the diagnosis and treatment of aneurysmal bone cysts (ABCs). ABCs are benign, but locally aggressive bone tumors that mainly affect children. ABCs comprise 1% of all primary bone tumors and occur most frequently during the first two decades of life. The diagnosis is made using a variety of imaging modalities and has the characteristic features of an expansile, radiolucent lesion that is often seen in the metaphyseal region of the bone and has fluid-fluid levels that are apparent on MRI. In the pediatric population, telangiectatic osteosarcoma and unicameral bone cyst (UBC) are the main differential diagnoses of an ABC. Giant cell tumors (GCTs) also include in differential diagnosis, which often manifest in patients older than 15 and do not penetrate the open physis although they develop after the physeal closure. Imaging alone cannot rule out telangiectatic osteosarcoma; therefore, a biopsy is recommended. A variety of treatment options have been described; traditionally, most patients are treated with curettage and bone grafting. Curettage alone, however, usually results in tumor recurrence following excision. A variety of adjuvants have been utilized with varying degrees of effectiveness to reduce the risk of local recurrence. When a cyst is in the pelvis, its location and size are such that surgery is a very risky option. Selective arterial embolization has significantly contributed to the development of effective treatments for these situations. Embolization or radiation, as well as denosumab therapy, are widely used as therapies for ABCs in anatomic locations where surgery would significantly increase morbidity.

    本文提供了三个最近提出的分数导数,即Caputo意义上的AtanganaBaleanu分数导数(ABC)描述的广义二级流体流之间的比较,卡普托·法布里齐奥(CF)和常数比例-卡普托混合(CPC)分数导数。在流过垂直多孔板的过程中观察到传热传质,该垂直多孔板在磁流体动力学的作用下呈指数加速。本文还分析了温度边界层的热产生和指数加热以及浓度边界层的化学反应的影响。流动模型由三个偏微分方程描述,并利用积分变换技术(拉普拉斯变换)将无量纲PDE集转换为ODE。为了更好地理解二级流体的流变特性,我们使用了CF,ABC和CPC运算符来描述记忆效应。问题的解析精确解以G函数和MittagLeffler函数的形式获得。对于流动参数的物理意义,不同的参数被绘制出来。从该分析可以得出结论,CPC是描述记忆效应的最合适的运算符。
    This article provides a comparison among the generalized Second Grade fluid flow described by three recently proposed fractional derivatives i.e. Atangana Baleanu fractional derivative in Caputo sense (ABC), Caputo Fabrizio (CF) and Constant Proportional-Caputo hybrid (CPC) fractional derivative. The heat mass transfer is observed during the flow past a vertical porous plate that is accelerated exponentially under the effects of the Magneto hydro dynamics. The effects of the heat generation and exponential heating in the temperature boundary layer and chemical reaction at the concentration boundary layer are also analyzed in this article. The flow model is described by three partial differential equations and the set of non-dimensional PDE\'s is transformed into ODE\'s by utilization of the integral transform technique (Laplace transform). For the better understanding of the rheological properties of the Second Grade fluid we used the CF, ABC and CPC operators to describe the memory effects. The analytical exact solution of the problem is obtained in the form of G-functions and Mittag Leffler functions. For the physical significance of flow parameters, different parameters are graphed. From this analysis it is concluded that the CPC is the most suitable operator to describe the memory effects.
