    大多数接受手术切除的胰腺癌患者最终会出现疾病复发。本研究旨在调查是否有证据支持胰腺癌手术后的常规监测,次要目的是分析北欧国家监测战略的实施情况。
    进行了范围审查,以确定全球临床实践指南和与胰腺癌切除术后监测相关的研究。随后,对来自四个北欧国家的20个胰腺单位进行了一项调查,以评估他们目前对手术患者进行随访的做法。
    共纳入16项临床实践指南和17项研究。该指南对胰腺癌术后监测提供了不一致的建议。临床研究数据主要基于回顾性队列研究,证据水平低,未解决前置时间偏差。瑞典和丹麦建议积极监测,但不在挪威超过手术/辅助期。芬兰没有关于监测的国家建议。北欧调查显示,不同单位之间的报告实践差异很大。大约75%(20个单位中的15个)进行了常规的术后监测。作为监测的一部分,80%使用常规CA19-9检测,67%使用常规CT。约73%的中心持续随访至术后5年。
    胰腺癌手术后常规长期(即5年)监测的证据仍然有限。北欧国家的大多数胰腺单位进行定期随访,但是协议各不相同。
    UNASSIGNED: Most patients with pancreatic cancer who have undergone surgical resection eventually develop disease recurrence. ‍This study aimed to investigate whether there is evidence to support routine surveillance after pancreatic cancer surgery, with a secondary aim of analyzing the implementation of surveillance strategies in the Nordic countries.
    UNASSIGNED: A scoping review was conducted to identify clinical practice guidelines globally and research studies relating to surveillance after pancreatic cancer resection. This was followed by a survey among 20 pancreatic units from four Nordic countries to assess their current practice of follow-up for operated patients.
    UNASSIGNED: Altogether 16 clinical practice guidelines and 17 research studies were included. The guidelines provided inconsistent recommendations regarding postoperative surveillance of pancreatic cancer. The clinical research data were mainly based on retrospective cohort studies with low level of evidence and lead-time bias was not addressed. Active surveillance was recommended in Sweden and Denmark, but not in Norway beyond the post-operative/adjuvant period. Finland had no national recommendations for surveillance. The Nordic survey revealed a wide variation in reported practice among the different units. About 75% (15 of 20 units) performed routine postoperative surveillance. Routine CA 19-9 testing was used by 80% and routine CT by 67% as part of surveillance. About 73% of centers continued follow-up until 5 years postoperatively.
    UNASSIGNED: Evidence for routine long-term (i.e. 5 years) surveillance after pancreatic cancer surgery remains limited. Most pancreatic units in the Nordic countries conduct regular follow-up, but protocols vary.

    目的:大约40%的激素难治性急性重度溃疡性结肠炎(激素难治性(SR)ASUC)患者需要结肠切除术。先进的治疗可能会降低SRASUC患者的短期结肠切除术率。然而,缺乏评估这些抢救疗法有效性的比较临床研究.因此,我们进行了一项网络荟萃分析,以研究SRASUC的抢救疗法的有效性.
    方法:分析了6项随机对照试验和15项队列研究,包括2,004例患者。救援药物包括托法替尼,在0、2和6周时使用5或10mg/kg诱导剂量的英夫利昔单抗(分别为IFX和IFX10),IFX采用根据临床需要定时的三个5mg/kg诱导剂量的加速方案(加速IFX),他克莫司,环孢菌素(CyA),ustekinumab,和阿达木单抗.将治疗与安慰剂进行比较。
    结果:托法替尼(优势比[OR]:0.09[95%置信区间[CI]:0.02-0.52]),加速IFX(OR:0.16[95%CI:0.03-0.94]),IFX(OR:0.2[95%CI:0.07-0.58]),与安慰剂相比,他克莫司(OR:0.24[95%CI:0.06-0.96])显著降低短期结肠切除术率.IFX10和CyA倾向于预防结肠切除术。然而,ustekinumab和阿达木单抗对结肠切除术率无显著影响.
    结论:这是第一个网络荟萃分析,旨在研究先进疗法在降低SRASUC患者短期结肠切除率方面的疗效。托法替尼,加速IFX,标准IFX,与安慰剂相比,他克莫司显著降低了SRASUC患者的结肠切除术率。因此,SRASUC患者的抢救治疗应考虑采用先进疗法.
    OBJECTIVE: Approximately 40% of patients with steroid-refractory acute severe ulcerative colitis (steroid-refractory (SR) ASUC) requires colectomies. Advanced therapies may reduce the short-term colectomy rates in patients with SR ASUC. However, comparative clinical studies evaluating the effectiveness of these rescue therapies are lacking. Therefore, we conducted a network meta-analysis to study the effectiveness of rescue therapies for SR ASUC.
    METHODS: Six randomized controlled trials and 15 cohort studies including 2,004 patients were analyzed. Rescue drugs included tofacitinib, infliximab with a 5 or 10 mg/kg induction dose at 0, 2, and 6 weeks (IFX and IFX10, respectively), IFX with an accelerated regimen of three 5 mg/kg induction doses timed according to clinical need (accelerated IFX), tacrolimus, cyclosporine (CyA), ustekinumab, and adalimumab. Treatments were compared with a placebo.
    RESULTS: Tofacitinib (odds ratio [OR]: 0.09 [95% confidence interval [CI]: 0.02-0.52]), accelerated IFX (OR: 0.16 [95% CI: 0.03-0.94]), IFX (OR: 0.2 [95% CI: 0.07-0.58]), and tacrolimus (OR: 0.24 [95% CI: 0.06-0.96]) significantly reduced the short-term colectomy rates compared with placebo. IFX10 and CyA tended to prevent colectomies. However, ustekinumab and adalimumab did not significantly affect the colectomy rates.
    CONCLUSIONS: This is the first network meta-analysis to investigate the efficacy of advanced therapies in reducing short-term colectomy rates in patients with SR ASUC. Tofacitinib, accelerated IFX, standard IFX, and tacrolimus significantly reduced the colectomy rates in SR ASUC patients compared with placebo. Thus, advanced therapies should be considered for rescue therapies in patients with SR ASUC.

    目的:本综述旨在评估免疫球蛋白轻链(AL)淀粉样变性复发/难治性患者接受预先达雷木单抗为基础的治疗方案。
    结果:AL淀粉样变性的治疗前景已经发生了根本性的变化,这要归功于daratumumab与硼替佐米的联合使用,环磷酰胺和地塞米松(DaraCyBorD)改善患者预后,增加血液和器官反应率。然而,许多患者最终复发或对达雷妥单抗无效,最佳的挽救治疗尚未明确.在这场比赛中,我们回顾了daratumumab失败后可用的治疗选择,我们着眼于目前Bcl-2抑制剂的进展,新型免疫治疗剂,如嵌合抗原受体(CAR-T)治疗和双特异性抗体(bsAbs)。复发/难治性AL淀粉样变性代表未满足的临床需求,新的靶向药物需要紧急前瞻性评估。
    OBJECTIVE: This review aims to assess the therapeutic strategies available for relapsed/refractory patients with immunoglobulin light chain (AL) amyloidosis who received upfront daratumumab-based regimens.
    RESULTS: The treatment landscape of AL amyloidosis has changed radically thanks to the introduction in the upfront setting of daratumumab in combination with bortezomib, cyclophosphamide and dexamethasone (DaraCyBorD) which improved patients\' outcomes increasing the rate of hematologic and organ responses. However, many patients eventually relapse or are refractory to daratumumab and the best salvage therapy is not well defined yet. In this contest, we reviewed the available therapeutic options after daratumumab failure, and we look towards the current advances in Bcl-2 inhibitors, novel immunotherapeutic agents as chimeric antigen receptor (CAR-T) therapy and bispecific antibodies (bsAbs). Relapsed/refractory AL amyloidosis represent an unmet clinical need and novel targeted drugs require urgent prospective assessment.

    地西泮是一种基石的即时使用的抗癫痫治疗,可以延长癫痫患者癫痫发作之间的持续时间。然而,由于缺乏合适的临床前模型,我们对间歇性抢救治疗对疾病进展的机制理解受到限制.具体来说,地西泮的药代动力学在人类和实验动物之间差异很大。这里,我们在大鼠中开发了一种新的重复挽救疗法给药模式,以维持在人类中观察到的延长的治疗浓度.大鼠接受了三个剂量的地西泮,间隔1小时(0.75、1.5或3mg/kg,腹膜内);最后一次给药后10分钟和1、3或6小时收集血浆和大脑。血浆和脑浓度遵循剂量依赖性增加,重复3mg/kg范例(180ng/mL)后的峰值浓度相当于地西泮鼻喷雾剂人体研究中观察到的血浆水平。在这种范例中,脑血浆比增加表明地西泮在大脑中的积累可能在作用部位起长效作用。总的来说,我们重复地西泮给药模式模拟了在人类中看到的药物浓度和积累,提供了一种临床前工具来研究苯二氮卓类药物抢救治疗对啮齿动物癫痫模型中癫痫发作集群生物学的影响。简单语言总结:还有更多关于地西泮如何在24小时内仅在两次或更多次癫痫发作时使用它的人的大脑中发挥作用(这被称为癫痫发作集群)。动物的伦理研究可用于了解体内药物的更多信息。在这项研究中,我们发现,在大鼠体内服用三剂地西泮给人的药物量与一剂相同。我们现在可以测试患有癫痫的大鼠,看看这种药物如何在需要癫痫发作时服用的人身上起作用。
    Diazepam is a cornerstone immediate-use antiseizure rescue therapy that may extend the duration between seizure clusters in people living with epilepsy. However, our mechanistic understanding of intermittent rescue therapy on disease progression is limited by the lack of suitable preclinical models. Specifically, the pharmacokinetics of diazepam varies widely between humans and laboratory animals. Here, we developed a novel repeat rescue therapy dosing paradigm in rats to maintain prolonged therapeutic concentrations seen in humans. Rats received three diazepam doses separated by 1 h (0.75, 1.5, or 3 mg/kg, intraperitoneal); plasma and brains were collected at 10 min and 1, 3, or 6 h following the last dose. Plasma and brain concentrations followed a dose-dependent increase with peak concentrations following the repeat 3 mg/kg paradigm (180 ng/mL) being equivalent to plasma levels observed in human studies with diazepam nasal spray. Increased brain-to-plasma ratios in this paradigm indicate that diazepam accumulation in the brain may be long-acting at the site of action. Overall, our repeat diazepam dosing paradigm mimics drug concentrations and accumulation seen in humans, offering a preclinical tool to study the impact of benzodiazepine rescue therapy on seizure-cluster biology in rodent models of epilepsy. PLAIN LANGUAGE SUMMARY: There is more to learn about how diazepam works in the brains of people who use it only when they have two or more seizures in 24 h (this is called a seizure cluster). Ethical studies in animals can be used to learn more about medicines in the body. In this study, we showed that three doses of diazepam in rats give about the same amount of the drug as one dose for a person. We can now test rats with epilepsy to see how the drug might work in people who take it when needed for seizure clusters.

    神经昼夜节律的影响,包括睡眠/觉醒过渡,进程(例如,荷尔蒙变化),和行为模式(例如,食用食物和口服药物),可能会影响癫痫发作模式。据报道,癫痫发作的具体昼夜节律模式取决于类型,发病位置,和严重程度;然而,关于癫痫群集患者的模式和一天中时间的抢救治疗有效性的数据有限.
    我们使用地西泮鼻喷雾剂3期安全性研究的患者日记数据进行了事后分析,适用于年龄≥6岁的癫痫患者的癫痫发作集群的急性治疗。给予患者基于年龄和体重的剂量;如果需要控制癫痫发作群,可以给予第二剂量。我们评估了癫痫发作-集群发作的时钟时间以及第二剂量的使用作为有效性的代表。记录治疗引起的不良事件。
    在早晨和深夜,癫痫发作通常最高,在傍晚和深夜最低。第二剂量的使用与一天中的特定时间并不一致。安全性与先前地西泮鼻喷雾剂研究的预期一致。
    这些结果表明,地西泮鼻喷雾剂可以在一天中的任何时间有效给药。
    UNASSIGNED: Neurologic circadian influences, including sleep/wake transitions, processes (e.g., hormonal variation), and behavioral patterns (e.g., consumption of food and oral medications), may affect seizure patterns. Specific circadian patterns of seizures have been reported depending on type, onset location, and severity; however, data on patterns for patients with seizure clusters and effectiveness of rescue therapy by time of day are limited.
    UNASSIGNED: We conducted post hoc analyses using patient diary data from the phase 3 safety study of diazepam nasal spray, which is indicated for acute treatment of seizure clusters in patients with epilepsy aged ≥6 years. Patients were administered age- and weight-based doses; second doses could be administered if needed to control a seizure cluster. We assessed clock timing of seizure-cluster onset along with second-dose use as a proxy for effectiveness. Treatment-emergent adverse events were recorded.
    UNASSIGNED: Seizure-cluster onset was observed to be generally highest during mornings and late evenings and lowest in the early evening and middle of the night. Second-dose use was not consistently associated with a specific time of day. The safety profile was consistent with that expected from previous studies of diazepam nasal spray.
    UNASSIGNED: These results suggest that diazepam nasal spray can be effectively administered at any time of day.

    SARS病毒家族的最新病毒称为急性综合征-冠状病毒-2(SARS-CoV-2),导致COVID-19疾病,于2019年底在中国确定。2020年3月,在它传播到另外29个国家之后,世界卫生组织(WHO)宣布它为大流行。SARS-CoV-2感染主要通过呼吸道开始,并引起从无症状感染到急性呼吸窘迫综合征并伴有多器官衰竭和血管麻痹性休克的广泛症状。在已研究用于治疗COVID-19的许多免疫调节和抗病毒药物中,亚甲蓝(MB)可能起着重要作用。本文回顾了MB应用程序的历史,MB对SARS-CoV-2的抗病毒作用,以及MB在COVID-19中使用的体内和体外研究结果。根据研究,由于其多种特性,MB可以同时影响SARS-CoV-2感染引起的大多数宿主的有害反应,包括抗低氧血症,抗氧化剂,免疫系统调节剂,和抗病毒。MB的使用与感染可能性的降低有关,和死亡率,可以用作保险箱,有效,便宜,和可用的治疗选择,副作用最小,可用于COVID-19的临床管理。
    The newest virus from the SARS family of viruses called acute syndrome-coronavirus-2 (SARS-CoV-2), which causes COVID-19 disease, was identified in China at the end of 2019. In March 2020, after it spread to 29 additional countries, it was declared a pandemic by the World Health Organization (WHO). SARS-CoV-2 infection mainly starts through the respiratory tract and causes a wide spectrum of symptoms from asymptomatic infections to acute respiratory distress syndrome with multi-organ failure and vasoplegic shock. Among the many immunomodulatory and antiviral drugs that have been studied for the treatment of COVID-19, methylene blue (MB) may play an influential role. This article reviews the history of MB applications, the antiviral effects of MB against SARS-CoV-2, and the results of in vivo and in vitro studies of the use of MB in COVID-19. Based on studies, MB can simultaneously affect most of the host\'s harmful responses caused by SARS-CoV-2 infection due to its multiple properties, including anti-hypoxemia, anti-oxidant, immune system modulator, and antiviral. The use of MB is associated with a reduction in the possibility of getting infection, and mortality, and can be used as a safe, effective, cheap, and available treatment option with minimal side effects for the clinical management of COVID-19.

    目的:描述安全性,并发症,需要住院治疗英夫利昔单抗治疗急性克罗恩病(CD)发作的患者需要紧急手术。
    背景:英夫利昔单抗越来越多地用于急性重症溃疡性结肠炎住院患者的抢救治疗;然而,对因CD耀斑住院患者的最佳管理仍不清楚.
    方法:对2008年至2020年收治的18岁以上急性克罗恩病发作患者进行单机构回顾性研究,需要进行抢救英夫利昔单抗治疗。结果包括术后和药物相关的并发症以及紧急手术的需要。
    结果:52例患者被纳入分析;8%的患者在入院时需要手术,19%的患者在英夫利昔单抗治疗90天内需要手术治疗.术后并发症包括吻合口瘘1例,3浅表伤口感染,3延长肠梗阻,1例泌尿系感染。输注英夫利昔单抗无不良反应,医疗并发症发生率低。穿透性疾病患者在英夫利昔单抗治疗90天内更有可能接受手术(43%vs8%;P=.01)。与未接受治疗的患者相比,在治疗后90天内接受手术的患者的平均LOS更长(13.4天vs8.3天,P=.04)。
    结论:除了标准的类固醇治疗外,住院抢救英夫利昔单抗对于治疗急性克罗恩病发作是安全的。大多数因克罗恩病发作而住院的患者需要抢救英夫利昔单抗避免了手术,术后并发症和药物相关并发症较低。需要更多的研究来阐明最佳的抢救英夫利昔单抗治疗剂量。
    OBJECTIVE: Describe the safety, complications, and need for urgent surgery in patients requiring inpatient rescue infliximab for acute Crohn\'s disease (CD) flare.
    BACKGROUND: Infliximab is increasingly used for patients hospitalized with acute severe ulcerative colitis as rescue therapy; however, optimal management for patients hospitalized for CD flares remains unclear.
    METHODS: A single-institution retrospective study of patients aged 18+ admitted from 2008 to 2020 with acute Crohn\'s flare requiring induction of rescue infliximab therapy. Outcomes included postoperative and medication-related complications and need for urgent surgery.
    RESULTS: 52 patients were included in analysis; 8% required surgery on index admission, and 19% required surgery within 90 days of infliximab. Postoperative complications included 1 anastomotic leak, 3 superficial wound infections, 3 prolonged ileus, and 1 urinary infection. There were no adverse reactions to infliximab infusion, and medical complication rates were low. Patients with penetrating disease were more likely to undergo surgery within 90 days of infliximab (43% vs 8%; P = .01). Mean LOS was longer for patients undergoing surgery within 90 days of therapy compared to those who did not (13.4 vs 8.3 days, P = .04).
    CONCLUSIONS: Inpatient rescue infliximab is safe for treating acute Crohn\'s disease flare in addition to standard steroid therapy. The majority of patients hospitalized with Crohn\'s flare requiring rescue infliximab avoided surgery with low postoperative and medication-related complications. More research is needed to clarify the optimal rescue infliximab therapy dosage.

    Yu等人在《世界胃肠病学杂志》(2023年)上的研究介绍了沃诺拉赞-阿莫西林双重疗法联合布拉氏酵母菌(S.boulardii)用于针对幽门螺杆菌(H.pylori),引起消化性溃疡和胃癌的病原体。沃诺拉赞是一种钾竞争性酸阻滞剂,以其快速和持久的酸抑制作用而闻名。受进餐时间的影响最小。与质子泵抑制剂相比,不可逆地与H+/K+-ATP酶泵中的半胱氨酸残基结合,Vonoprazan与K+离子竞争,防止离子与泵结合并阻止酸分泌。对抗生素耐药性增加的担忧,对肠道微生物群的影响,患者依从性,和副作用导致幽门螺杆菌双重治疗方案的出现。先前的研究表明,布拉氏链球菌在稳定肠屏障中发挥作用,从而提高幽门螺杆菌的根除率。具有可接受的安全性,无论以前的治疗失败和抗生素耐药性如何,双重辅助方案都是有效的,从而加强在临床环境中的适用性。尽管如此,布拉氏链球菌有各种配方和剂量,有必要进一步探索抢救治疗中补充的最佳剂量。此外,较大,随机化,有必要进行双盲对照试验以证实这些有希望的结果.
    Yu et al\'s study in the World Journal of Gastroenterology (2023) introduced a novel regimen of Vonoprazan-amoxicillin dual therapy combined with Saccharomyces boulardii (S. boulardii) for the rescue therapy against Helicobacter pylori (H. pylori), a pathogen responsible for peptic ulcers and gastric cancer. Vonoprazan is a potassium-competitive acid blocker renowned for its rapid and long-lasting acid suppression, which is minimally affected by mealtime. Compared to proton pump inhibitors, which bind irreversibly to cysteine residues in the H+/K+-ATPase pump, Vonoprazan competes with the K+ ions, prevents the ions from binding to the pump and blocks acid secretion. Concerns with increasing antibiotic resistance, effects on the gut microbiota, patient compliance, and side effects have led to the advent of a dual regimen for H. pylori. Previous studies suggested that S. boulardii plays a role in stabilizing the gut barrier which improves H. pylori eradication rate. With an acceptable safety profile, the dual-adjunct regimen was effective regardless of prior treatment failure and antibiotic resistance profile, thereby strengthening the applicability in clinical settings. Nonetheless, S. boulardii comes in various formulations and dosages, warranting further exploration into the optimal dosage for supplementation in rescue therapy. Additionally, larger, randomized, double-blinded controlled trials are warranted to confirm these promising results.
