Objectives

To establish a model for prediction of recurrence of non-small cell lung cancer (NSCLC) based on clinical data and computed tomography (CT) imaging characteristics.

Methods

A total of 695 patients with surgically resected NSCLC confirmed by pathology at three centers were retrospectively investigated. 626 patients from center 1 were randomly divided into two sets in a ratio of 7:3 (training set, n = 438; testing set, n = 188), 69 patients from center 2 and 3 were assigned in the external validation set. Univariate and binary logistic regression analyses of clinical and CT imaging features determined the independent risk factors used to construct the model. The receiver-operating characteristic curve nomogram and decision curves analysis were used to evaluate the predictive ability of the model.

Results

The mean patient age was 63.3 ± 10.1 years, and 44.7 % (311/695) were male. The univariate and binary logistic regression analyses identified four independent risk factors (age, tumor markers, consolidation/tumor ratio, and pleural effusion), which were used to construct the prediction model. In the training set, the model had an area under the curve of 0.857, an accuracy of 71.7 %, a sensitivity of 88.1 %, and a specificity of 70.0 %; in the testing set, the respective values were 0.867, 75.5 %, 94.4 %, and 73.5 %; in the external validation set, the respective values were 0.852, 79.7 %, 83.3 %, 78.9 %.

Conclusion

A prediction model based on clinical data and CT imaging characteristics showed excellent efficiency in prediction of recurrence of NSCLC. Clinical use of this model could be useful for selection of appropriate treatment options.

Purpose

To determine to what extent colorectal liver metastases (CRLM) display typical imaging characteristics on gadoxetic acid-enhanced magnetic resonance imaging (MRI) and what changes after chemotherapy.

Methods

We retrospectively identified 258 patients with a gadoxetic acid-enhanced MRI between 2015 and 2021 and pathologically proven non-mucinous adenocarcinoma CRLM. 722 unique CRLMs were analyzed: 378 CRLM in only the chemotherapy-naïve analysis; 217 in post-chemotherapy analysis; and 127 CRLM were analyzed both pre- and post-chemotherapy. The following six characteristics were defined as typical; “hypovascular”, “unenhanced T1-weighted (UE-T1W) hypointensity”, “arterial rim enhancement”, “non-enhancing during hepatobiliary phase”, “T2-weighted (T2W) mild hyperintensity”, and “diffusion restriction”.

Results

All six typical characteristics were found in 249/505 chemotherapy-naïve CRLM (49 %) and 87/344 post-chemotherapy CRLM (25 %). The occurrence of some typical characteristics decreased post-chemotherapy: UE-T1W hypointensity 485/505 (96 %) versus 311/336 (93 %), arterial rim enhancement 291/498 (58 %) versus 154/301 (51 %), T2W mild hyperintensity 478/505 (95 %) versus 269/338 (79 %), and diffusion restriction 435/497 (87 %) versus 200/306 (65 %). Almost all metastases showed a hypovascular appearance, both in the chemotherapy-naïve (495/504, 98 %) and post-chemotherapy group (330/331, 100 %). Additionally, all CRLM appeared non-enhancing compared to the liver in the hepatobiliary phase (100 %).

Conclusion

Most CRLM show various combinations of at least five typical characteristics on gadoxetic acid-enhanced MRI. Arterial rim enhancement is the least prevalent characteristic both in chemotherapy-naïve and post-chemotherapy patients. Post-chemotherapy the occurrence of typical MRI characteristics decreases, especially mild T2W hyperintensity and the presence of diffusion restriction.

Injectable dermal fillers have seen a remarkable rise in popularity in recent years for aesthetic enhancements, such as facial contouring and rejuvenation. Hyaluronic acid (HA)-based fillers are especially favored due to their tolerability, minimal invasiveness, and effectiveness. This review examines the applications of ultrasound in HA dermal filler procedures. A literature search was conducted from February 25 to 26, 2024, using Medline and Google Scholar to identify relevant studies on the use of ultrasound for facial HA dermal fillers. Inclusion criteria included peer-reviewed English language studies from the last decade and involving living human subjects. Eleven studies met these criteria. The findings indicate that ultrasound significantly enhances the accuracy and safety of HA filler procedures by enabling precise vascular mapping, filler detection, and complication detection and identification. By presenting evidence of reduced risks and improved outcomes, this review underscores the potential for ultrasound to become a standard tool in HA filler applications, representing an innovation and a new application for ultrasound in the field of aesthetic dermatology.

Purpose

To perform a nationwide analysis of ablation compared to partial and total nephrectomy for the management of renal cell carcinoma (RCC) to evaluate utilization trends and disparities in the USA.

Materials and methods

The 2016–2020 National Inpatient Sample was analyzed. Using ICD-10, we identified the diagnosis of RCC then analyzed the utilization trends of ablation and nephrectomies (both partial and complete). To determine if any disparities exist, a multivariate logistic regression was performed to assess the influence of age, sex, race, income, payer, illness severity, geographical location, and hospital factors.

Results

From the 183,885 inpatient encounters with RCC, 3045 (1.65 %) underwent ablation, 70,080 (38.1 %) underwent partial nephrectomy, and 110,760 (60.2 %) underwent total nephrectomy. There was no significant difference in the sex between all groups. There was a statistically significant difference in the mean age of those undergoing ablation (67.30, SD = 12.05) versus those undergoing partial nephrectomy (59.27, SD = 13.26) and total nephrectomy (62.22, SD = 14.42) (OR: 1.04, 95%CI: 1.03–1.05, P < 0.001). Compared to White patients, Hispanic and African Americans were more likely to undergo ablation versus nephrectomy (OR: 1.52, 95%CI: 1.16–1.98, P = 0.002 and OR: 1.65, 95%CI: 1.28–2.13, P < 0.001, respectively). Compared to patients on private insurance, those on Medicaid and Medicare were more likely to have ablation than nephrectomy (OR: 1.85, 95%CI: 1.31–2.61, P < 0.001, and OR: 1.62, 95%CI: 1.26–2.08, P < 0.001, respectively). Furthermore, patients were less likely to undergo ablation than nephrectomies in 2020 compared to 2016 (OR: 0.69, 95%CI: 0.53–0.90, P = 0.006).

Conclusion

Since 2016, there has been a decreasing trend in the use of ablation for treating RCC in hospitalized patients. Those undergoing ablation tend to be older, African American, Hispanic, and insured by Medicare or Medicaid. Further research is needed to ensure equitable access for optimal treatment of RCC.

All of us must find the right balance between team science and fostering leadership with dynamic colleagues. That dichotomy was well-encapsulated in a famous exchange between basketball players Shaquille O'Neal and Kobe Bryant regarding there “being no ‘I’ in team”. In our view, there is nothing more satisfying than collaborating with a team of people and publishing impactful papers or making key discoveries. At the same time, there are innumerable instances of collaborations stumbling along and the team failing to gel in a meaningful way. Strong leaders may be very important to propagating the overall team approach. Those leaders may be acknowledging that the team is composed of individuals who all bring something to the table. In this way, a diversity of backgrounds of the individual teammates makes the team stronger. The key, of course, is to find the right team and build within that team a strong foundation. Ultimately, we need to emphasize the importance of both team science and individual excellence in our work. In this manuscript, we will emphasize that as scientific endeavor continues to become more complex, leveraging diverse teams will be increasingly important – but also that team success cannot come at the expense of the uniquely talented individual.
我们所有人都必须在团队科学和培养充满活力的同事的领导能力之间找到适当的平衡。篮球运动员沙奎尔·奥尼尔和科比·布莱恩特之间关于“团队中没有自我”的著名交流很好地概括了这种二分法。在我们看来,没有什么比与一个团队合作、发表有影响力的论文或做出重大发现更令人满意的了。与此同时,也有无数的合作受挫的例子,团队无法以一种有意义的方式团结起来。强有力的领导者可能对宣传整体团队方法非常重要。这些领导者可能会承认,团队是由个人组成的,他们都能带来一些东西。通过这种方式,队友个人背景的多样性使团队更加强大。当然,关键是找到合适的团队,并在这个团队中建立坚实的基础。最后,我们需要强调团队科学和个人卓越在工作中的重要性。在本文中,我们将强调,随着科学努力变得越来越复杂,利用不同的团队将变得越来越重要——但团队的成功不能以牺牲独特的人才为代价。

Purpose

To evaluate henna as a durable skin marker on various skin tones for sonographic targeting and to identify the shortest duration of henna application needed for practical clinical workflow.

Materials and methods

Prospective study applying seven henna lines through ultrasound (US) gel on the forearms of 15 healthy participants equally represented across the validated six-color bar tool. Color bar categories 1–2, 3–4, and 5–6 were designated low, moderate, and high-melanin groups, respectively. Each subsequent line was applied with staining wait-times ranging from 10 to 480 s. Serial photographs were obtained after scrubbing with chlorhexidine every 2–3 days with the number of clearly visible lines assessed by participants, by individual and consensus physician reads, and by band intensity quantification.

Results

Henna could be applied through US gel and the markings were resistant to chlorhexidine scrubbing. Staining wait-times for 60, 120, and 240 s resulted in visible lines for 6, 8, and 10 days (low-melanin), 5, 6, and 8 days (moderate-melanin), and 2, 3, and 4 days (high-melanin). No lines were visible on day 13 for most participants in the low or moderate-melanin groups and on day 6 on most participants in the high-melanin group. The marking intensities decreased more quickly in the moderate-melanin group compared the low-melanin group.

Conclusion

Henna is an effective skin marker that can be applied through US gel where short staining wait-times result in markings lasting several days. To achieve the same durability, staining wait-times are about double for high-melanin skin tones compared to low or moderate-melanin skin tones.
目的:评价指甲花作为不同肤色的持久皮肤标记物用于超声定位,并确定实际临床工作流程中指甲花应用所需的最短时间。材料和方法:前瞻性研究,通过超声凝胶在15名健康参与者的前臂上应用7条指甲花线,这些参与者使用经过验证的六色条工具。色条分类1-2、3-4、5-6分别为低、中、高黑色素组。随后的每条线应用染色,等待时间从10到480秒不等。每2-3天用氯己定擦洗后获得系列照片,由参与者、个人和共识医生读数以及波段强度量化评估清晰可见线的数量。结果:指甲花可通过US凝胶涂抹,斑点耐洗必泰擦洗。染色等待时间为60、120和240 s, 6、8和10天(低黑色素),5、6和8天(中等黑色素),2、3和4天(高黑色素)可见线。在第13天,大多数低黑色素组或中等黑色素组的参与者没有看到线条,在第6天,大多数高黑色素组的参与者没有看到线条。与低黑色素组相比,中等黑色素组的标记强度下降得更快。结论:指甲花是一种有效的皮肤标记,可以通过美国凝胶涂抹,染色时间短,标记持续数天。为了达到同样的耐久性,高黑色素肤色的染色等待时间大约是低或中等黑色素肤色的两倍。

Purpose

Though prior studies have proven CTC's efficacy in outpatients, its utility in the inpatient setting has not been studied. We evaluated the efficacy of a modified CTC protocol in the inpatient setting, primarily for patients awaiting organ transplantation.

Methods

This retrospective study compared a group of inpatient CTCs from 2019 to 2021 and a randomly selected, age-matched 2:1 control group of outpatient CTCs. Both groups were assessed based on established criteria from literature.

Results

10 % (63/652) of CTCs were performed in the inpatient setting, of which 29 were excluded, yielding 34 inpatient cases. 90 % (589/652) of CTCs were performed in the outpatient setting, from which 68 randomly selected, age-matched patients were selected as controls. Significantly more (24 %, 8/34) inpatients expired due to extracolonic causes (vs. 1 %, 1/68 outpatients, p < 0.05). 62 % (21/34) of inpatient CTCs were reported as diagnostic (vs. 74 %, 50/68 outpatient, p = 0.22). Significantly more inpatients (12 %, 4/34) than outpatients (1 %, 1/68) were unable to tolerate two imaging positions (p = 0.02). Subsequent colonoscopy was performed in 24 % (8/34) of inpatients, revealing pathologies including colonic polyps and non-bleeding ulcers. Inpatient CTCs had lower average quality scores, significant for one reviewer (p = 0.009–0.054). Inpatients had a larger number of segments with: >25 % residual fluid (1.22–1.28 inpatients vs. 0.60–0.73 outpatients, p = 0.003–0.026) and inadequate fluid tagging (1.10 inpatients vs. 0.49 outpatients, p = 0.046–0.0501). Distention was not significantly different between groups (p = 0.317–0.410).

Conclusion

Quality of inpatient CTC was inferior to outpatient CTCs across several metrics. 24 % undergoing inpatient CTC died of extracolonic causes within 22 months, and most did not have findings warranting intervention, questioning the value of this difficult exam in this patient population. Routine CT may be sufficient to exclude large or metastatic colonic lesions precluding transplant.

Background

Congenital heart diseases (CHDs) are common birth defects. This work presents over four years of clinical experience of 4D flow cardiovascular magnetic resonance (CMR), highlighting its value for pediatric CHD.

Methods

Children with various CHD diagnoses (n = 298) were examined on a 1.5 or 3 T scanner using 4D flow CMR in free breathing with respiratory compensation. The image volume was acquired in axial orientation, covering the entire heart and major vessels. Head-to-head comparisons with reference standards were systematically performed.

Results

4D flow CMR provided more detailed insights into complex cardiovascular conditions while maintaining a comparable level of accuracy in peak velocity, Q and Qp/Qs (R = 0.9–1.0) compared to conventional 2D flow CMR. The advantages of 4D flow CMR were particularly evident for valve function, stenosis, and shunt assessments. However, our findings emphasize the need for additional corrections to address partial volume (up to 180 % error in perfusion ratio) and through-plane cardiac motion effects (up to 25/10 ml error in aortic/pulmonary regurgitation volume).

Conclusion

Overall, 4D flow CMR proved to be a comprehensive diagnostic tool that enhanced the understanding and management of pediatric CHD, potentially changing the course of the treatment.
背景:先天性心脏病(CHDs)是常见的先天性缺陷。本文介绍了4年多来心血管磁共振(CMR)的临床经验,强调了其在小儿冠心病中的价值。方法:对298例不同诊断的CHD患儿进行自由呼吸呼吸补偿4D血流CMR 1.5 T或3t扫描检查。图像体积在轴向上获得,覆盖整个心脏和主要血管。系统地进行了与参考标准的直接比较。结果:与传统的二维血流CMR相比,4D血流CMR在保持峰值流速、Q和Qp/Qs (R = 0.9-1.0)的准确度的同时,对复杂的心血管疾病提供了更详细的见解。4D血流CMR在瓣膜功能、狭窄和分流评估方面的优势尤为明显。然而,我们的研究结果强调需要额外的校正来解决部分容积(灌注比误差高达180%)和贯穿平面的心脏运动影响(主动脉/肺反流容积误差高达25/ 10ml)。结论:总的来说,4D血流CMR被证明是一种全面的诊断工具,增强了对儿童冠心病的认识和管理,有可能改变治疗过程。
