Cabozantinib for relapsed neuroblastoma: Single institution case series

Relapsed high‐risk neuroblastoma has few effective therapies currently available or in development. Cabozantinib is an Food and Drug Administration approved multitargeted tyrosine kinase inhibitor for select adult malignancies with preclinical data suggesting efficacy against neuroblastoma. A safe and tolerable dose has been identified for children, but its efficacy remains unknown. We describe four children with relapsed metastatic neuroblastoma treated with cabozantinib. All four patients had extended disease control (two complete responsesfor >12 months, 2 stable disease >6 months) with manageable predictable toxicities requiring dose reduction in two patients. We discuss the potential for the use of cabozantinib in neuroblastoma.     

腹腔镜"蘑菇状"剜除术治疗外生性肾血管平滑肌脂肪瘤的临床应用

目的对比研究腹腔镜下外生性肾血管平滑肌脂肪瘤"蘑菇状"剜除与标准肾部分切除术的安全性及有效性，为肾血管平滑肌脂肪瘤腹腔镜下"蘑菇状"剜除术术式的建立提供临床依据。 方法选取海南医学院第二附属医院与解放军总医院2018年1月至2019年5月期间，接受腹腔镜手术的肾血管平滑肌脂肪瘤患者53例，其中25例沿肿瘤假包膜行"蘑菇状"剜除术(A组)、28例行肾部分切除术(B组)。比较两组手术患者的肾动脉阻断时间、手术时间、术中出血量、术后24 h血红蛋白、术后eGFR(estimated glomerular filtration rate,估计肾小球率过滤)的变化、术后住院时间和术后肿瘤复发率。 结果53例手术无术中转开放，无死亡病例。肾动脉阻断时间：A组(11.9±2.2)min、B组(21.5±6.5) min(P<0.001)。手术时间：A组(87.9±24.8)min、B组(114.3±38.9) min(P<0.001)。术中出血量：A组20 ml(20～40)ml、B组50 ml(50～100)ml(P<0.001)。术后24 h血红蛋白变化：A组(7.4±4.3) g/L、B组(12.4±8.8) g/L(P＝0.013)。术后24 h eGFR变化：A组(6.2±7.2 )ml(min·1.73 m²)，B组(12.7±12.8)ml(min·1.73 m²)(P＝0.027)。术后6个月eGFR变化：A组(1.5±3.7)ml(min·1.73 m²)、B组(6.5±5.6)ml(min·1.73 m²)(P<0.001)。术后住院时间：A组4.0 d(3～4)d、B组4.5 d(3～6)d(P＝0.023)。术后随访两组术后肿瘤均无复发。 结论采用腹腔镜"蘑菇状"剜除术治疗外生性肾血管平滑肌脂肪瘤在肾动脉阻断时间、术中出血量、术后24 h血红蛋白、术后eGFR变化、术后住院时间等方面均优于传统肾部分切除术，两组术后肿瘤均无复发；该方法安全、有效，适于临床推广。     

Biomarker directed chronic wound therapy – A new treatment paradigm

AimTo develop a treatment paradigm for chronic leg ulcers that incorporates new biomarkers of wound healing with currently available therapies.MethodsRecently published data on GM-CSF and MMP-13 as biomarkers of venous leg ulcer (VLU) healing status with accuracies of 92% and 78% respectively, was reviewed along with the wound bed preparation (WBP) theoretical framework for treatment of chronic wounds. The broad categories of wound treatments that align with the WBP concepts were identified. These were then considered in a hierarchical order that initially improves the wound bed and subsequently incorporates more complex advanced wound therapies. Identification of the non-healing status of the wound is the driver to advance through the different treatments.ResultsA point of care test of wound healing status is the key to the systematic use of currently available therapies for chronic leg ulcers in a timely fashion. The different therapies address – debridement, moisture control, bacterial contamination, protease inhibition, formation of granulation tissue, application of growth factors, application of matrix constructs, and application of cellular components. Progression through this hierarchical order of therapies is directed by the leg ulcer remaining in a non-healing state with the previous therapies having been implemented.ConclusionCombining a validated point of care test of wound healing with a systematic approach to wound therapies, has the potential to create a new paradigm of chronic leg ulcer treatment - biomarker directed wound therapy.     

急性前葡萄膜炎中医体质与生存质量的相关性

目的：评估急性前葡萄膜炎患者中医体质与生存质量的相关性。方法：横断面研究。选取2014年12月 至2017年12月于温州医科大学附属眼视光医院中医眼科专科就诊并经体质评分判定为病理体质的 患者196例，应用中华生存质量量表进行生存质量评分。采用t检验及线性回归分析中医体质与生存 质量评分各领域的相关性。结果：196例患者中单纯体质者147例，复合体质者49例。经广义线性回 归分析，患者的不同体质类型及体质评分与中华生存质量量表评分有显著相关性，进一步分析发现 体质评分与中华生存质量量表评分中的形、情有显著相关性（均P<0.05），与神无显著相关。经线性 回归分析，不同类型中医体质中，气虚、痰湿、血瘀、阳虚、阴虚体质与中华生存质量量表中的形有 显著相关性（均P<0.05）；气郁体质与情有显著相关性（P=0.001）；而湿热体质与形和情均有显著相关 性（均P<0.001）。结论：急性前葡萄膜炎患者的不同中医体质与中医生存质量密切相关，且对形的影 响最大。

Mock jurors’ awareness of age-related changes in memory and cognitive capacity

While age-related changes in memory have been well documented, findings about jurors’ perceptions of older witnesses are conflicting. We investigated the effect of victim age (25 vs. 75?years old) and crime severity (victim injured vs. not injured) on mock jurors’ decisions in a robbery trial. Jury-eligible participants (120 women; 84 men) read a mock trial summary and delivered their verdicts online. Mock jurors believed the young victim more than the older victim when the crime was severe, while no age differences emerged for the less severe crime. Whereas previous research demonstrated that juror characteristics were generally associated with culpability, we demonstrated that with case-specific information, these general views became less important. In all, mock jurors were aware of age-related decline in memory provided by eyewitnesses only to a limited extent. Accordingly, in trials involving older witnesses, jurors will benefit from educative information about age-related memory changes.     

International Hand Function Study Following Distal Radial Access: The RATATOUILLE Study

BackgroundDistal radial access (DRA) has been proposed to improve procedure ergonomics and favor radial artery patency. Although promising data, nothing is known on evolving hand function after DRA.ObjectivesThis study sought to comprehensively evaluate hand function in patients undergoing DRA.MethodsReal-world patients undergoing DRA undertook a thorough multimodality assessment of hand function implementing multidomain questionnaires (Disabilities of the Arm, Shoulder and Hand and Levine-Katz), and motor (pinch grip test) and sensory (Semmes-Weinstein monofilaments test) examinations of both hands. All assessments were performed at preprocedural baseline and planned at 1-, 6-, and 12-month follow-up (FU). Adverse clinical and procedural events were documented too.ResultsData of 313 patients (220 men, age 66 ± 10 years) from 9 international centers were analyzed. The Disabilities of the Arm, Shoulder and Hand and the Levine-Katz scores slightly improved from baseline to FU (P = 0.008 and P = 0.029, respectively). Pinch strength mildly improved from baseline to FU (P < 0.001 for both the left and right hands). Similarly, touch pressure threshold appeared to faintly improve in both the left and right hands (P < 0.012 for all the sites). For both motor and sensory function tests, comparable findings were found for the DRA hand and the contralateral one, with no significant differences between them. Repeated assessment of all tests over all FU time points similarly showed lack of worsening hand function. Access-related adverse events included 19 harmless bleedings and 3 forearm radial artery and 3 distal radial artery occlusions. None affected hand function at FU.ConclusionsIn a systematic multidimensional assessment, DRA was not associated with hand function impairment. Moreover, DRA emerges as a safe alternative vascular access.
