    OBJECTIVE: This randomized controlled trial evaluated the effect of virtual reality (VR) distraction and fatigue training on anxiety and fatigue in children with cancer.
    METHODS: The sample of this parallel design randomized controlled trial consisted of 41 children aged 7 to 16 who were receiving chemotherapy treatment in the pediatric hematology and oncology wards of a university hospital. Data was collected with the Child Anxiety Scale-State, Child Fatigue Scale-24-Hours, and Visual Fatigue Scale in both groups before and during the first three days of chemotherapy treatment. All children admitted to the clinic during chemotherapy received fatigue education. On the first, second, and third days of chemotherapy treatment, children in the study group underwent a 15-minute VR distraction intervention following stratified randomization. Repeated measures analysis of variance was used to compare scale scores by group, time, and group-time interaction.
    RESULTS: Of the patients, 63.4% were male, and 39% had neuroblastoma. There was no difference between the groups in terms of diagnosis, age, duration of diagnosis, chemotherapy, or hemoglobin levels. A statistically significant difference was found between the mean scores of the anxiety and fatigue scores in the intervention and control groups in terms of group, time, and group-time interaction.
    CONCLUSIONS: Applying VR distraction on the first, second, and third days of chemotherapy treatment was found to be useful in lowering anxiety and fatigue levels in addition to fatigue training.
    CONCLUSIONS: Virtual reality distraction is an effective method for reducing anxiety and fatigue in this population.

    Purpose  There have been numerous advancements in the strategies used for treating mandibular fractures in the present times, while open reduction and internal fixation is still accepted as the most preferred treatment option for such fractures despite numerous drawbacks. The aim of the present prospective, randomized controlled study was to evaluate the clinical outcome including neurosensory deficit and pain score variables in mandibular fractures that were treated using rigid internal fixation with three-dimensional (3D) miniplate internal fixation. Materials and Methods  For the present study, a total of 20 patients of either sex in an age range of 18 to 55 years with simultaneous angle and contralateral body/parasymphysis fractures of the mandible were included, while the clinical outcome was compared in relation to the two groups wherein different treatment options were used including using rigid internal fixation in one as against 3D miniplate internal fixation in the other. Results  Pairwise comparison of pain scores in Group I and Group II patients by the Mann-Whitney U-test at different time zones revealed the results to be statistically significant for all pairs except when the findings were compared between 1 month and 3 months after the procedure in Group II patients. Also, significant recovery was observed in both Group I and II patients during healing when assessed preoperatively to 1 month and then 3 months after the procedure with the results being statistically highly significant in case of the variations observed in relation to the neurosensory deficit observed at different time zones for both Group I and II patients ( p  = 0.0001). Conclusion  Based on the results obtained, it can be concluded that 3D miniplate-led osteosynthesis was found comparable to the osteosynthesis accomplished using reconstruction plates during fixation of unfavorable body/parasymphysis fractures of mandible in study, providing optimal stability, while satisfactorily meeting the biomechanical requirements for occlusal loading, and an early return to normal function.

    背景:寻常疣(VV)是儿童常见的病毒性疾病。由于疼痛或不良反应风险,儿童的治疗选择通常不能很好地耐受。非热大气等离子体(NTAP)产生活性氧/氮物质,耐受性良好,无不良影响。
    目的:确定NTAP与标准护理(SOC)治疗儿童VV的疗效。
    方法:这项前瞻性开放标签研究将病变1:1随机分组接受NTAP或SOC(冷冻治疗)。以4周的间隔对患者进行最多3次治疗。在最终治疗后4周评估他们的持续反应。主要结果是病变反应。
    结果:纳入14例患者的112个VV病变。患者主要是白人(92.9%)男性(71.4%),平均年龄为9.5[±2.5]岁。SOC和NTAP治疗的病变的反应分别包括:无反应(5.4%,7.1%);部分反应(33.9%,41.1%);和完全分辨率(60.7%,51.8%;p值=0.679)。患者在治疗后更可能报告SOC病变疼痛(p值<0.001)。无明显不良事件发生。
    结论:限制包括单站点,最多三种治疗,和短期的治疗后随访。
    结论:NTAP是一种有效的,儿童VV治疗的安全干预。
    BACKGROUND: Verruca vulgaris (VV) is a common viral disease in children. Treatment options are often not well-tolerated in children due to pain or adverse effect risk. Nonthermal atmospheric plasma (NTAP), which generates reactive oxygen/nitrogen species, is well-tolerated and without adverse effects.
    OBJECTIVE: Determine efficacy of NTAP as compared to standard of care (SOC) therapy for VV in children.
    METHODS: This prospective open-label study randomized lesions 1:1 to receive NTAP or SOC (cryotherapy). Patients were treated at 4-week intervals for a maximum of 3 treatments. They were evaluated four weeks post-final treatment for sustained response. Primary outcome was lesion response.
    RESULTS: 112 VV lesions in 14 patients were enrolled. Patients were mostly white (92.9%) males (71.4%) with mean age of 9.5 [±2.5] years. Responses of SOC- and NTAP-treated lesions respectively included: no response (5.4%, 7.1%); partial response (33.9%, 41.1%); and complete resolution (60.7%, 51.8%; p-value=0.679). Patients were more likely to report pain in SOC lesions post-treatment (p-value<0.001). No significant adverse events (AEs) occurred.
    CONCLUSIONS: Limitations include single-site, maximum of three treatments, and short post-treatment follow-up.
    CONCLUSIONS: NTAP is an efficacious, safe intervention for treatment of VV in children.

    目的:精确评估术后容量状态对于实施最佳液体管理很重要。使用电特性测量身体成分的生物电阻抗分析(BIA)。BIA的细胞外水(ECW)比率表示为ECW与总体内水(TBW)的比率,并且已知反映水合状态。基于此,我们的目的是确定使用ECW比率进行积极的液体控制是否可以通过单盲法改善临床结果,随机对照试验。
    方法:从2021年11月至2022年12月,将术后收治的重症监护病房(ICU)患者随机分为干预组或对照组,无论术后液体管理是否通过BIA控制。在干预组的患者中,脱水患者接受大剂量输注晶体液,而对过度水合的患者使用利尿剂,直至ECW比值在其正常设定范围(0.390-0.406)内.相反,对照组每天进行一次BIA。对照组患者接受传统的液体治疗,无论BIA结果如何。主要结果是两组的院内死亡率。次要结果是术后并发症,28天死亡率。
    结果:最终分析干预组77例和对照组90例。院内死亡率(干预中为0,4.4%的控制,p=0.125)和28天死亡率(干预率为1.3%,控制14.4%,p=0.002)显示干预组的发病率低于对照组。在多变量分析中,ECW比超过0.406[比值比(OR):2.731,95%置信区间(CI):1.001~7.663,p=0.049]的过度水合状态和ICU入院时的高毛细血管渗漏指数(CLI)(OR:1.024,95%CI:1.008~1.039,p=0.002)是术后并发症的危险因素.关于28天死亡率,高CLI值(OR:1.025,95%CI:1.002-1.050,p=0.037)和不进行BIA监测的传统策略(OR:9.903,95%CI:1.095-89.566,p=0.041)是显著的诱发因素。
    结论:我们的结果表明,通过BIA进行基于ECW比率的严格液体治疗与容量控制未能显著改善住院死亡率,但它可以降低ICU患者的28天死亡率。监测ECW比率可能有助于为术后ICU患者建立最佳的液体治疗策略,这些患者易受液体失衡和液体超负荷的影响。
    背景:ClinicalTrials.gov,NCT06097923,于2023年10月16日回顾性注册,https://clinicaltrials.gov/study/NCT06097923?term=NCT06097923&rank=1。
    OBJECTIVE: Precise assessment of postoperative volume status is important to administrate optimal fluid management. Bioelectrical impedance analysis (BIA) which measures the body composition using electric character. Extracellular water (ECW) ratio by BIA represented as the ratio of ECW to total body water (TBW) and is known to reflect the hydration status. Based on this, we aimed to determine whether aggressive fluid control using ECW ratio could improve clinical outcomes through a single blind, randomized controlled trial.
    METHODS: From November 2021 to December 2022, intensive care unit (ICU) patients admitted after surgery were randomly assigned to an intervention group or a control group whether postoperative fluid management was controlled via BIA. Among patients in the intervention group, dehydrated patients received a bolus infusion with crystalloid fluid whereas diuretics were administrated to overhydrated patients until the value of ECW ratio fell within its normal setting range (0.390-0.406). Contrarily, BIA was performed once a day for the control group. Patients in the control group received traditional fluid treatment regardless of BIA results. Primary outcome was in-hospital mortality in two groups. The secondary outcomes were postoperative morbidities, 28-day mortality.
    RESULTS: 77 patients of the intervention group and 90 patients of the control group were finally analyzed. The in-hospital mortality (0 in intervention, 4.4% in control, p = 0.125) and 28-day mortality (1.3% in intervention, 14.4% in control, p = 0.002) showed lower incidence in the intervention group than in the control group. In multivariate analysis, the overhydrated status whose ECW ratio exceeding 0.406 [odds ratio (OR): 2.731, 95% confidence interval (CI): 1.001-7.663, p = 0.049] and high capillary leak index (CLI) value at ICU admission (OR: 1.024, 95% CI: 1.008-1.039, p = 0.002) were risk factors of postoperative morbidities. Regarding the 28-day mortality, high CLI value (OR: 1.025, 95% CI: 1.002-1.050, p = 0.037) and traditional strategy without BIA monitoring (OR: 9.903, 95% CI: 1.095-89.566, p = 0.041) were the significant predisposing factors.
    CONCLUSIONS: Our results revealed the rigorous fluid treatment with volume control based on ECW ratio by BIA failed to achieve significant improvement in in-hospital mortality, but it could reduce 28-day mortality of ICU patients. Monitoring of ECW ratio may help establish optimal fluid treatment strategies for postoperative ICU patients who are susceptible to fluid imbalances with fluid overload.

    OBJECTIVE: We aimed to identify a safe and effective method to assist older adults with pneumonia in tolerating the prone position for a longer duration.
    METHODS: This was a randomized, controlled, double-blinded study performed at the Shanghai Fourth People\'s Hospital. Eighty patients with pneumonia aged ≥ 65 years were included. The patients were able to spontaneous breath in the prone position and were administered intravenous dexmedetomidine or an isotonic sodium chloride solution. The cumulative daily durations of prone positioning for all patients in the two groups were recorded. The primary outcome was the percentage of patients who completed ≥ 9 h/day in the prone position. The secondary outcomes included the incidence of complications in the prone position and patient outcomes.
    RESULTS: Eighty patients were included (average age: 79.6 ± 8.9 years). The percentage of patients who completed ≥ 9 h/day in the prone position was significantly higher in the dexmedetomidine group than in the placebo group (P = 0.011). The percentage of patients who completed ≥ 12 h/day in the prone position was also significantly greater in the dexmedetomidine group than in the placebo group (P = 0.008). There were no significant differences in other variables between the two groups.
    CONCLUSIONS: The results of this study demonstrate that intravenous dexmedetomidine injection can significantly prolong the duration of spontaneous breathing in the prone position in elderly pneumonia patients without obvious adverse events. We provide a safe and effective method to help patients with pneumonia, especially those with delirium or cognitive impairment, who cannot tolerate the length of time needed for spontaneous breathing in the prone position to be effective.
    BACKGROUND: The study was registered with the Chinese Clinical Trial Center (registration number: ChiCRT2300067383) on 2023-01-05.

    背景:尽管传统上使用水飞蓟素进行肝脏保护,目前,关于水飞蓟素在治疗代谢功能障碍相关的脂肪变性肝病(MASLD)中的有效性的随机对照试验(RCT)研究有限且尚无定论,特别是当它单独使用时。水飞蓟素的低生物利用度突出了肠道菌群对水飞蓟素有效性的可能影响;然而,没有人类研究调查这方面。
    目的:确定水飞蓟素在改善MASLD指标方面的潜在功效,并研究与肠道菌群相关的潜在机制。
    方法:在这项为期24周的随机研究中,双盲,安慰剂对照试验,83例MASLD患者随机接受安慰剂(n=41)或水飞蓟素(103.2mg/d,n=42)。在0、12和24周,使用FibroScan评估肝脏硬度和肝脏脂肪变性,收集血液样本进行生化检测,而在第0周和第24周收集粪便样品进行16SrRNA测序。
    结果:水飞蓟素补充剂显着降低了肝脏硬度(LSM,-0.21±0.17vs.0.41±0.17,P=0.015)和血清γ-谷氨酰转肽酶(GGT,-8.21±3.01vs.1.23±3.16,P=0.042)和ApoB(-0.02±0.03vs.0.07±0.03,P=0.023),但对受控衰减参数(CAP)没有显着影响,其他生化指标(转氨酶,总胆红素,葡萄糖和脂质参数,hsCRP,SOD,和UA),物理测量(DBP,SBP,BMI,WHR,BF%,和BMR),或APRI和FIB-4指数。肠道菌群分析显示,水飞蓟素组的物种多样性和蛇尾科的富集增加。
    结论:这些发现表明水飞蓟素补充剂可以改善MASLD患者的肝脏硬度,可能是通过调节肠道微生物群。
    背景:该试验已在中国临床试验注册中心(ChiCTR2200059043)注册。
    BACKGROUND: Despite centuries of traditional use of silymarin for hepatoprotection, current randomized controlled trial (RCT) studies on the effectiveness of silymarin in managing metabolic dysfunction-associated steatotic liver disease (MASLD) are limited and inconclusive, particularly when it is administered alone. The low bioavailability of silymarin highlights the possible influence of gut microbiota on the effectiveness of silymarin; however, no human studies have investigated this aspect.
    OBJECTIVE: To determine the potential efficacy of silymarin in improving MASLD indicators and to investigate the underlying mechanisms related to gut microbiota.
    METHODS: In this 24-week randomized, double-blind, placebo-controlled trial, 83 patients with MASLD were randomized to either placebo (n = 41) or silymarin (103.2 mg/d, n = 42). At 0, 12, and 24 weeks, liver stiffness and hepatic steatosis were assessed using FibroScan, and blood samples were gathered for biochemical detection, while faecal samples were collected at 0 and 24 weeks for 16S rRNA sequencing.
    RESULTS: Silymarin supplementation significantly reduced liver stiffness (LSM, -0.21 ± 0.17 vs. 0.41 ± 0.17, P = 0.015) and serum levels of γ-glutamyl transpeptidase (GGT, -8.21 ± 3.01 vs. 1.23 ± 3.16, P = 0.042) and ApoB (-0.02 ± 0.03 vs. 0.07 ± 0.03, P = 0.023) but had no significant effect on the controlled attenuation parameter (CAP), other biochemical indicators (aminotransferases, total bilirubin, glucose and lipid parameters, hsCRP, SOD, and UA), physical measurements (DBP, SBP, BMI, WHR, BF%, and BMR), or APRI and FIB-4 indices. Gut microbiota analysis revealed increased species diversity and enrichment of Oscillospiraceae in the silymarin group.
    CONCLUSIONS: These findings suggest that silymarin supplementation could improve liver stiffness in MASLD patients, possibly by modulating the gut microbiota.
    BACKGROUND: The trial was registered at the Chinese Clinical Trial Registry (ChiCTR2200059043).

    背景技术在蛛网膜下腔阻滞期间经常使用佐剂来增强和延长镇痛并减少高剂量局部麻醉剂的副作用。鞘内芬太尼与高压布比卡因预混已用于脊髓麻醉,并与在单独的注射器中连续使用这些药物进行了比较。然而,鉴于文学的匮乏,我们进行了这项研究,在血流动力学方面比较了鞘内芬太尼与高压布比卡因的预混前后给药,块特性,和血液动力学改变。方法论这个前瞻性的,随机化,我们对随机分为4组的160例患者进行了三盲对比研究.A组(n=40)(对照组)通过5.0mL注射器接受3.0mL(15mg)0.5%高压布比卡因和0.5mL生理盐水。B组(n=40)通过单个5.0mL注射器接受3.0mL(15mg)0.5%高压布比卡因和0.5mL(25µg)芬太尼预混。C组(n=40)通过1.0mL注射器接受0.5mL(25μg)芬太尼,然后通过5.0mL注射器接受3.0mL(15mg)0.5%高压布比卡因。D组(n=40)通过5.0mL注射器接受3.0mL(15mg)0.5%高压布比卡因,然后通过1.0mL注射器接受0.5mL(25µg)芬太尼。感觉和运动阻滞的发作和消退,血液动力学参数,第一次抢救镇痛的时间,并观察不良事件。数据分析使用SPSS17.0版(SPSSStatisticsInc.,芝加哥,IL,美国)。结果D组感觉和运动阻滞的平均发作时间最少,其次是C组。D组感觉和运动阻滞的持续时间延长。A组患者低血压的发生率高于B组,C,C组和D组延迟了抢救镇痛的要求。结论在15mg(3.0mL)0.5%的高压布比卡因后单独施用25µg(0.5mL)芬太尼可导致感觉和运动阻滞的早期发作和持续时间延长,术中血流动力学稳定性,术后延迟需要抢救镇痛,与作为预混溶液或高压布比卡因的先行剂联合给药相比,副作用更少。
    Background Adjuvants are often used during subarachnoid block to enhance and prolong the analgesia and decrease the adverse effects of high doses of local anesthetic agents. Intrathecal fentanyl premixed with hyperbaric bupivacaine has been used in spinal anesthesia and compared with the sequential use of these drugs in separate syringes. However, given the paucity of literature, we conducted this study where premixed antecedent and succedent administration of intrathecal fentanyl with hyperbaric bupivacaine were compared in terms of flow dynamics, block characteristics, and hemodynamic alterations. Methodology This prospective, randomized, triple-blinded comparative study was conducted among 160 patients who were randomly allocated into four groups. Group A (n = 40) (control) received 3.0 mL (15 mg) of 0.5% hyperbaric bupivacaine and 0.5 mL of normal saline via a 5.0 mL syringe. Group B (n = 40) received 3.0 mL (15 mg) of 0.5% hyperbaric bupivacaine and 0.5 mL (25 µg) of fentanyl premixed via a single 5.0 mL syringe. Group C (n = 40) received 0.5 mL (25 µg) of fentanyl via a 1.0 mL syringe followed by 3.0 mL (15 mg) of 0.5% hyperbaric bupivacaine via a 5.0 mL syringe. Group D (n = 40) received 3.0 mL (15 mg) of 0.5% hyperbaric bupivacaine via a 5.0 mL syringe followed by 0.5 mL (25 µg) of fentanyl via a 1.0 mL syringe. The onset and regression of sensory and motor blockade, hemodynamic parameters, time to first rescue analgesia, and adverse events were observed. Data analysis was done using SPSS version 17.0 (SPSS Statistics Inc., Chicago, IL, USA). Results The mean time taken for the onset of sensory and motor blockade was least in Group D followed by Group C. Duration of sensory and motor blockade was prolonged in Group D. Patients in Group A experienced more hypotension than Groups B, C, and D. Requirement of rescue analgesia was delayed in Groups C and D. Conclusions Administering 25 µg (0.5 mL) of Fentanyl separately after 15 mg (3.0 mL) of 0.5% hyperbaric bupivacaine results in early onset and prolonged duration of sensory and motor blockade, intraoperative hemodynamic stability, the delayed requirement of rescue analgesia postoperatively, and fewer side effects compared to its co-administration as a premixed solution or antecedent to hyperbaric bupivacaine.

    背景:吲哚胺2,3-双加氧酶1(IDO1)是一种免疫抑制酶,与尿路上皮癌(UC)患者的疾病特异性生存期较短有关。IDO1可能抵消免疫检查点抑制剂的抗肿瘤作用。Epacadostat是一种有效且高度选择性的IDO1抑制剂。在I/II阶段ECHO-202/KEYNOTE-037研究中,在一组晚期UC患者中,epacadostat+pembrolizumab的初步客观缓解率(ORR)为35%.
    方法:ECHO-307/KEYNOTE-672是双盲,随机化,第三阶段研究。符合条件的成年人已确认尿路局部晚期/不可切除或转移性UC,并且没有资格接受基于顺铂的化疗。参与者被随机分配(1:1)接受epacadostat(每天两次100mg)加pembrolizumab(每3周200mg)或安慰剂加pembrolizumab,最多35次pembrolizumab输注。主要终点是研究者根据实体瘤的反应评估标准(1.1版)评估的ORR。
    结果:共有93例患者被随机分组(epacadostat+pembrolizumab,n=44;安慰剂加帕博利珠单抗,n=49)。由于来自第三阶段ECHO-301/KEYNOTE-252研究的新数据,提前停止了登记。两组的中位随访时间为64天。根据截止时的所有可用数据,epacadostat+pembrolizumab的ORR(未经证实)为31.8%(95%CI,22.46-55.24%),安慰剂+pembrolizumab的ORR为24.5%(95%CI,15.33-43.67%)。在安慰剂加帕博利珠单抗组中,循环犬尿氨酸水平从C1D1增加到C2D1,在epacadostat加帕博利珠单抗组中降低。Epacadostat+pembrolizumab联合治疗耐受性良好,安全性与安慰剂组相似。epacadostat患者因治疗相关不良事件而停止治疗的频率更高(11.6%vs.4.1%)。
    结论:在先前未经治疗的局部晚期/不可切除或转移性UC不合格的顺铂患者中,epacadostat联合pembrolizumab治疗与安慰剂联合pembrolizumab的ORR和安全性相似。每天两次100毫克的剂量,epacadostat与pembrolizumab联合给药时,似乎不能使循环犬尿氨酸水平完全正常化.更大的研究,随访时间更长,可能测试更高剂量的epacadostat,可能在不同的治疗环境中,可以保证。

    BACKGROUND: Indoleamine 2,3- dioxygenase 1 (IDO1) is an immunosuppressive enzyme that has been correlated with shorter disease-specific survival in patients with urothelial carcinoma (UC). IDO1 may counteract the antitumor effects of immune checkpoint inhibitors. Epacadostat is a potent and highly selective inhibitor of IDO1. In the phase I/II ECHO-202/KEYNOTE-037 study, epacadostat plus pembrolizumab resulted in a preliminary objective response rate (ORR) of 35% in a cohort of patients with advanced UC.
    METHODS: ECHO-307/KEYNOTE-672 was a double-blinded, randomized, phase III study. Eligible adults had confirmed locally advanced/unresectable or metastatic UC of the urinary tract and were ineligible to receive cisplatin-based chemotherapy. Participants were randomly assigned (1:1) to receive epacadostat (100 mg twice daily) plus pembrolizumab (200 mg every 3 weeks) or placebo plus pembrolizumab for up to 35 pembrolizumab infusions. The primary endpoint was investigator-assessed ORR per Response Evaluation Criteria in Solid Tumors (version 1.1).
    RESULTS: A total of 93 patients were randomized (epacadostat plus pembrolizumab, n = 44; placebo plus pembrolizumab, n = 49). Enrollment was stopped early due to emerging data from the phase III ECHO-301/KEYNOTE-252 study. The median duration of follow-up was 64 days in both arms. Based on all available data at cutoff, ORR (unconfirmed) was 31.8% (95% CI, 22.46-55.24%) for epacadostat plus pembrolizumab and 24.5% (95% CI, 15.33-43.67%) for placebo plus pembrolizumab. Circulating kynurenine levels numerically increased from C1D1 to C2D1 in the placebo-plus-pembrolizumab arm and decreased in the epacadostat-plus-pembrolizumab arm. Epacadostat-plus-pembrolizumab combination treatment was well tolerated with a safety profile similar to the placebo arm. Treatment discontinuations due to treatment-related adverse events were more frequent with epacadostat (11.6% vs. 4.1%).
    CONCLUSIONS: Treatment with epacadostat plus pembrolizumab resulted in a similar ORR and safety profile as placebo plus pembrolizumab in cisplatin-ineligible patients with previously untreated locally advanced/unresectable or metastatic UC. At a dose of 100 mg twice daily, epacadostat did not appear to completely normalize circulating kynurenine levels when administered with pembrolizumab. Larger studies with longer follow-up and possibly testing higher doses of epacadostat, potentially in different therapy settings, may be warranted.

  • 文章类型: Journal Article
    背景:吲哚胺2,3-双加氧酶1(IDO1)水平与尿路上皮癌(UC)的不良预后相关。IDO1和程序性死亡配体1(PD-L1)通常共表达。Epacadostat是一种有效且高度选择性的IDO1抑制剂。在参加I/II期研究的晚期UC患者的亚组分析中,epacadostat-pembrolizumab治疗的客观缓解率(ORR)为35%.
    方法:ECHO-303/KEYNOTE-698是双盲,针对转移性或不可切除的局部晚期UC患者进行随机III期研究,并在铂类一线化疗后复发或进展.参与者被随机分配给每天两次(BID)100mg的epacadostat或安慰剂加pembrolizumab,直到35次pembrolizumab输注完成,疾病进展,或不可接受的毒性。主要终点是根据1.1版实体瘤的反应评估标准研究者评估的ORR。
    结果:目标入组为648名患者;根据ECHO-301/KEYNOTE-252转移性黑色素瘤III期研究的疗效结果,提前停止入组。42名患者被随机分配到每个治疗组。每组的中位随访时间为62天。研究者评估的ORR(未经证实)对于epacadostat+pembrolizumab为26.2%(95%CI16.35-48.11),对于安慰剂+pembrolizumab为11.9%(95%CI4.67-29.50)。报告了两个完整的答复,两者都在安慰剂加帕博利珠单抗组。在安慰剂加帕博利珠单抗组中,循环犬尿氨酸水平从C1D1增加到C2D1,在epacadostat加帕博利珠单抗组中数字下降。epacadostat联合pembrolizumab的安全性与pembrolizumab单药相似,尽管组合中的患者比例高于对照组经历了与治疗相关的≥3级不良事件(16.7%vs.7.3%)。每个手臂都有一名患者死于心血管事件,不被认为与药物有关。没有发现任何一个代理商的新安全问题。
    结论:Epacadostat联合pembrolizumab显示出抗肿瘤活性,并且作为二线治疗不可切除的局部晚期或复发/进展性转移性UC患者通常可以耐受。Epacadostat100毫克BID,当与pembrolizumab一起给药时,大多数患者的循环犬尿氨酸未恢复正常。对该患者人群中IDO1/PD-L1联合抑制的进一步研究,特别是使用导致循环犬尿氨酸持久正常化的epacadostat剂量,可以保证。
    背景:ClinicalTrials.gov,NCT03374488。注册2017年12月15日。
    BACKGROUND: Indoleamine 2,3-dioxygenase 1 (IDO1) levels correlate with poor outcomes in urothelial carcinoma (UC). IDO1 and programmed death-ligand 1 (PD-L1) are often co-expressed. Epacadostat is a potent and highly selective inhibitor of IDO1. In a subgroup analysis of patients with advanced UC participating in a phase I/II study, epacadostat-pembrolizumab treatment produced an objective response rate (ORR) of 35%.
    METHODS: ECHO-303/KEYNOTE-698 was a double-blinded, randomized phase III study of adults with metastatic or unresectable locally advanced UC with recurrence or progression following first-line platinum-based chemotherapy. Participants were randomized to epacadostat 100 mg twice daily (BID) plus pembrolizumab or placebo plus pembrolizumab until completion of 35 pembrolizumab infusions, disease progression, or unacceptable toxicity. The primary endpoint was investigator-assessed ORR per Response Evaluation Criteria in Solid Tumors version 1.1.
    RESULTS: Target enrollment was 648 patients; enrollment was halted early based on efficacy results from the phase III ECHO-301/KEYNOTE-252 study in metastatic melanoma. Forty-two patients were randomized to each treatment arm. Median duration of follow-up was 62 days in each arm. The investigator-assessed ORR (unconfirmed) was 26.2% (95% CI 16.35-48.11) for epacadostat plus pembrolizumab and 11.9% (95% CI 4.67-29.50) for placebo plus pembrolizumab. Two complete responses were reported, both in the placebo-plus-pembrolizumab arm. Circulating kynurenine levels increased from C1D1 to C2D1 in the placebo-plus-pembrolizumab arm and numerically decreased in the epacadostat-plus-pembrolizumab arm. The safety profile of epacadostat plus pembrolizumab was similar to that of pembrolizumab monotherapy, although a numerically greater proportion of patients in the combination vs. control arm experienced treatment-related grade ≥ 3 adverse events (16.7% vs. 7.3%). One patient in each arm died due to cardiovascular events, which were not deemed drug-related. No new safety concerns were identified for either agent.
    CONCLUSIONS: Epacadostat plus pembrolizumab demonstrated anti-tumor activity and was generally tolerable as second-line treatment of patients with unresectable locally advanced or recurrent/progressive metastatic UC. Epacadostat 100 mg BID, when administered with pembrolizumab, did not normalize circulating kynurenine in most patients. Further study of combined IDO1/PD-L1 inhibition in this patient population, particularly with epacadostat doses that result in durable normalization of circulating kynurenine, may be warranted.

    活性氧(ROS)在生理过程中起着关键作用。然而,ROS和抗氧化剂之间的不平衡有利于前者导致与多种病理有关的氧化应激。由于其独特的属性,包括卓越的渗透性和选择性抗氧化能力,分子氢(H2)已经成为一种必不可少的治疗剂。氢吸入疗法(HIT)已成为对抗氧化应激的有希望的策略。在这项随机对照研究中,我们旨在评估HIT降低血液ROS水平的有效性.37名ROS水平升高(d-ROM值>350U.CARR)的参与者被纳入研究。参与者分为测试组和对照组。测试组参与者接受了HIT,然后在治疗后和24小时后立即测量他们的血液ROS水平。将他们的结果与未经历HIT的对照组参与者进行比较。试验组显示治疗后血液ROS水平显著降低。这些发现表明HIT在减少氧化应激方面的功效。
    Reactive Oxygen Species (ROS) play a key role in physiological processes. However, the imbalance between ROS and antioxidants in favor of the former causes oxidative stress linked to numerous pathologies. Due to its unique attributes, including distinguished permeability and selective antioxidant capability, molecular hydrogen (H2) has become an essential therapeutic agent. Hydrogen Inhalation Therapy (HIT) has come to light as a promising strategy to counteract oxidative stress. In this randomized controlled study, we aimed to evaluate the effectiveness of HIT in reducing blood ROS levels. 37 participants with elevated ROS levels (d-ROMs value > 350 U.CARR) were enrolled in the study. Participants were divided into test and control groups. The test group participants received HIT, and then their blood ROS levels were measured immediately post-treatment and after 24 h. Their results were compared to those of the control group participants who did not undergo HIT. The test group demonstrated a significant reduction in blood ROS levels after the treatment. These findings suggested the efficacy of HIT in reducing oxidative stress.
