  • 文章类型: Journal Article
    纤维肌痛综合征(FMS)是一种多方面的慢性疼痛障碍,对患者的总体健康状况和生活质量产生重大影响。
    研究运动疗法和遵守美国运动医学学院(ACSM)指南对FMS患者治疗结果的影响。
    文献检索,这项研究于2023年10月结束,涵盖了调查运动干预对FMS患者的影响的研究,并为计算标准化平均差(SMD)提供了足够的数据.主要结果指标包括纤维肌痛影响问卷(FIQ)和健康评估问卷(HAQ)。而次要结果指标包括疼痛水平,睡眠质量,疲劳,和心理健康。
    在4,008条记录中,19项研究(患者=857)符合定性综合条件。荟萃分析显示,总体健康状况影响的SMD为-0.94(95CI-1.26,-0.63),ACSM指南依从性高的亚组的合并SMD为-1.17(95CI-1.65,-0.69).依从性低或不确定的亚组的SMD为-0.73(95CI-1.12,-0.34)。总体效果包括-1.21(95CI-1.62,-0.79)SMD用于缓解疼痛,高依从性达到-1.32(95CI-2.00,-0.64)SMD,低依从性达到-1.06(95CI-1.55,-0.57)SMD。心理健康改善显示整体SMD为-0.95(95CI-1.32,-0.57),高和低依从性亚组在-0.96(95CI-1.62,-0.30)和-0.94(95CI-1.29,-0.60),分别。睡眠质量总体影响为-1.59(95CI-2.31,-0.87),高依从性为-1.71(95CI-2.58,-0.83),低依从性为-1.11(95CI-1.88,-0.33)。疲劳冲击的整体SMD为-1.55(95CI-2.26,-0.85),高依从性为-1.77(95CI-3.18,-0.36),低依从性为-1.35(95CI-2.03,-0.66)。
    运动疗法可以改善整体健康状态,疼痛,睡眠,和FMS患者的疲劳,特别是在遵守ACSM准则时。然而,依从性水平不会影响心理健康的提高,这表明需要对心理影响进行未来的研究。

    UNASSIGNED: The Fibromyalgia Syndrome (FMS) is a multifaceted chronic pain disorder that exerts a substantial impact on the overall state of health and quality of life of patients.
    UNASSIGNED: Investigate the effects of exercise therapy and adherence to the American College of Sports Medicine (ACSM) guidelines on treatment outcomes in FMS patients.
    UNASSIGNED: The literature search, which concluded in October 2023, encompassed studies investigating the impact of exercise interventions on patients diagnosed with FMS and providing adequate data for calculating standardized mean difference (SMD). The primary outcome measures encompassed the Fibromyalgia Impact Questionnaire (FIQ) and Health Assessment Questionnaire (HAQ), while secondary outcome measures comprised pain levels, sleep quality, fatigue, and mental health.
    UNASSIGNED: Among 4,008 records, 19 studies (patients = 857) were eligible for qualitative synthesis. The meta-analysis revealed that the SMD for overall state of health impact was -0.94 (95%CI -1.26, -0.63), and the pooled SMD for the subgroup with high adherence to ACSM guidelines was -1.17 (95%CI -1.65, -0.69). The SMD for the subgroup with low or uncertain adherence was -0.73 (95%CI -1.12, -0.34). The overall effects included a -1.21 (95%CI -1.62, -0.79) SMD for pain relief, with high adherence achieving a -1.32 (95%CI -2.00, -0.64) SMD and low adherence a -1.06 (95%CI -1.55, -0.57) SMD. Mental health improvements showed a -0.95 (95%CI -1.32, -0.57) overall SMD, with high and low adherence subgroups at -0.96 (95%CI -1.62, -0.30) and -0.94 (95%CI -1.29, -0.60), respectively. Sleep quality impact was -1.59 (95%CI -2.31, -0.87) overall, with high adherence at -1.71 (95%CI -2.58, -0.83) and low adherence at -1.11 (95%CI -1.88, -0.33). Fatigue impact had a -1.55 (95%CI -2.26, -0.85) overall SMD, with -1.77 (95%CI -3.18, -0.36) for high adherence and -1.35 (95%CI -2.03, -0.66) for low adherence.
    UNASSIGNED: Exercise therapy can improve the overall state of health, pain, sleep, and fatigue of FMS patients, particularly when adhering to ACSM guidelines. However, adherence levels do not affect mental health gains, indicating a need for future research on psychological impact.

    背景:许多研究已经评估了粪便微生物群移植(FMT)作为溃疡性结肠炎(UC)治疗的有效性和安全性。然而,这些研究的治疗过程和结果各不相同.
    目的:通过系统荟萃分析评价FMT治疗UC的有效性和安全性。
    方法:纳入标准涉及FMT治疗的成人UC患者的报告,而未报告临床结局或纳入感染患者的研究被排除.临床缓解(CR)和内镜缓解(ER)是主要和次要结果,分别。
    结果:我们纳入了从五个电子数据库检索的9项研究。FMT组的CR优于对照组[相对危险度(RR)=1.53;95%置信区间(CI):1.19-1.94;P<0.0008]。两组ER比较差异有统计学意义(RR=2.80;95CI:1.93~4.05;P<0.00001)。两组之间的不良事件没有显着差异。
    结论:FMT表现出良好的性能和安全性;然而,在推荐广泛使用FMT之前,仍需要精心设计的随机临床试验.此外,为了提高安全性和有效性,迫切需要使FMT流程标准化.
    BACKGROUND: Numerous studies have assessed the efficacy and safety of fecal microbiota transplantation (FMT) as a therapy for ulcerative colitis (UC). However, the treatment processes and outcomes of these studies vary.
    OBJECTIVE: To evaluate the efficacy and safety of FMT for treating UC by conducting a systematic meta-analysis.
    METHODS: The inclusion criteria involved reports of adult patients with UC treated with FMT, while studies that did not report clinical outcomes or that included patients with infection were excluded. Clinical remission (CR) and endoscopic remission (ER) were the primary and secondary outcomes, respectively.
    RESULTS: We included nine studies retrieved from five electronic databases. The FMT group had better CR than the control group [relative risk (RR) = 1.53; 95% confidence interval (CI): 1.19-1.94; P < 0.0008]. ER was statistically significantly different between the two groups (RR = 2.80; 95%CI: 1.93-4.05; P < 0.00001). Adverse events did not differ significantly between the two groups.
    CONCLUSIONS: FMT demonstrates favorable performance and safety; however, well-designed randomized clinical trials are still needed before the widespread use of FMT can be recommended. Furthermore, standardizing the FMT process is urgently needed for improved safety and efficacy.

    背景:由于治疗的快速发展性质,卒中指南声明对临床医生来说是重要的参考。指南声明应该由最新的系统评价(SRs)和荟萃分析(MAs)告知,因为它们提供了最高水平的证据。调查SRs/MAs在卒中管理指南中的应用,我们对指南进行了文献综述,并提取了有关SRs/MA的相关信息.
    方法:在PubMed中使用Trip医学数据库进行了文献综述,以术语“卒中”为目标人群,后跟使用筛选器“指南”。我们提取了包含的SR/MA的数量,出版的岁月,原产国,和其他兴趣特征。使用R软件版本4.2.1生成描述性统计。
    结果:我们包括27个指南声明。指南中总SR或MA的中位数为4.0(四分位距[IQR]=2-9)。仅对于MA,纳入指南的中位数为3.0(IQR=2.0-5.5).加拿大的指南有最古老的引文,最长引文的中位数差距为12.0年(IQR=5.2-18.0年),其次是欧洲(中位数=12;IQR=9.5-13.5)和美国(中位数=10.0;IQR=5.2-16)指南.
    结论:卒中指南编写小组和发布机构应更努力地将最新的SRs/MA纳入其指南声明中,以便临床医生可以参考最新的数据和最高水平的证据。
    BACKGROUND: Stroke guideline statements are important references for clinicians due to the rapidly evolving nature of treatments. Guideline statements should be informed by up-to-date systematic reviews (SRs) and meta-analyses (MAs) because they provide the highest level of evidence. To investigate the utilization of SRs/MAs in stroke management guidelines, we conducted a literature review of guidelines and extracted relevant information regarding SRs/MAs.
    METHODS: A literature review was conducted in PubMed with supplementation using the Trip medical database with the term \"stroke\" as the target population, followed by using the filter \"guidelines\". We extracted the number of included SRs/MAs, the years of publication, the country of origin, and other characteristics of interest. Descriptive statistics were generated using the R software version 4.2.1.
    RESULTS: We included 27 guideline statements. The median number of overall SRs or MAs within the guidelines was 4.0 (interquartile range [IQR] = 2-9). For MAs only, the median number included in the guidelines was 3.0 (IQR = 2.0-5.5). Canadian guidelines had the oldest citations, with a median gap of 12.0 (IQR = 5.2-18.0) years for the oldest citation, followed by European (median = 12; IQR = 9.5-13.5) and US (median = 10.0; IQR = 5.2-16) guidelines.
    CONCLUSIONS: Stroke guideline writing groups and issuing bodies should devote greater effort to the inclusion of up-to-date SRs/MAs in their guideline statements so that clinicians can reference recent data with the highest level of evidence.

    目的:比较PD-1和PD-L1抑制剂发生免疫相关性肺炎的风险,设计了荟萃分析。
    方法:通过两种不同的荟萃分析方法评估了PD-1和PD-L1抑制剂之间免疫相关性肺炎风险的差异,镜像配对和PRISMA指南。
    结果:共有88份报告用于荟萃分析,而32项研究用于镜像配对。PD-1和PD-L1抑制剂(单独使用或与化疗联合使用)都会增加发生免疫相关性肺炎的风险(P<0.00001;P<0.00001)。基于间接分析结果(子组分析),对照组化疗时,PD-L1诱导肺炎的风险弱于PD-1抑制剂(OR=3.33vs.5.43)或安慰剂(OR=2.53vs.3.19),差异无统计学意义(P=0.17;P=0.53)。对于基于镜像配对的荟萃分析,PD-1诱导肺炎的风险显著高于PD-L1抑制剂(OR=1.46,95CI[1.08,1.98],I2=0%,Z=2.47(P=0.01))。然而,这种差异并不显著,联合化疗时(OR=1.05,95CI[0.68,1.60],I2=38%,Z=0.21(P=0.84))。
    结论:PD-1和PD-L1抑制剂都会增加免疫相关性肺炎的风险,而PD-1诱导的肺炎风险明显高于PD-L1抑制剂。
    OBJECTIVE: To compare the risk of immune-associated pneumonitis between PD-1 and PD-L1 inhibitors, the meta-analysis was designed.
    METHODS: The difference in risk of immune-associated pneumonitis between PD-1 and PD-L1 inhibitors was assessed by two different meta-analysis methods, the Mirror-pairing and the PRISMA guidelines.
    RESULTS: A total of eighty-eight reports were used for meta-analysis, while thirty-two studies were used for the Mirror-pairing. Both PD-1 and PD-L1 inhibitors (used alone or combined with chemotherapy) increased the risk of developing immune-related pneumonitis (P < 0.00001; P < 0.00001). Based on indirect analyses results (subgroup analyses), the risk of PD-L1-induced pneumonitis was weaker than that of PD-1 inhibitors when the control group was chemotherapy (OR = 3.33 vs. 5.43) or placebo (OR = 2.53 vs. 3.19), while no obvious significant differences were found (P = 0.17; P = 0.53). For the Mirror-pairing-based meta-analysis, the risk of PD-1-induced pneumonitis was significantly higher than that of PD-L1 inhibitors (OR = 1.46, 95%CI [1.08, 1.98], I2 = 0%, Z = 2.47 (P = 0.01)). However, this difference was not significant, when they were combined with chemotherapy (OR = 1.05, 95%CI [0.68, 1.60], I2 = 38%, Z = 0.21 (P = 0.84)).
    CONCLUSIONS: Both PD-1 and PD-L1 inhibitors increased the risk of immune-related pneumonitis, while the risk of PD-1-induced pneumonitis was significantly higher than that of PD-L1 inhibitors.

    背景:乳腺癌化疗可导致中性粒细胞减少,增加发热性中性粒细胞减少症(FN)和严重感染的风险。已探索使用粒细胞集落刺激因子(G-CSF)作为初级预防来减轻这些风险。评价原发性G-CSF预防化疗对浸润性乳腺癌患者的疗效和安全性。
    方法:根据“临床实践指南开发思想手册”,使用PubMed进行了系统的文献综述,Ichushi-Web,和Cochrane图书馆数据库.包括随机对照试验(RCT)和队列研究,评估使用G-CSF作为浸润性乳腺癌的初级预防。主要结果是总生存率(OS)和FN发生率。对具有足够数据的结果进行Meta分析。
    结果:8项RCT纳入定性分析,5个RCT对FN发生率进行荟萃分析。荟萃分析显示,初次预防G-CSF的FN发生率显着降低(风险差异[RD]=0.22,95%CI:0.01-0.43,p=0.04)。G-CSF改善OS的证据尚无定论。四个随机对照试验表明,G-CSF有增加疼痛的趋势,但未报告有统计学意义.
    结论:强烈建议接受化疗的乳腺癌患者主要预防性使用G-CSF,因为它已被证明可以降低FN的发生率。虽然对操作系统的影响尚不清楚,减少FN的益处被认为大于疼痛增加的潜在危害.
    BACKGROUND: Chemotherapy for breast cancer can cause neutropenia, increasing the risk of febrile neutropenia (FN) and serious infections. The use of granulocyte colony-stimulating factors (G-CSF) as primary prophylaxis has been explored to mitigate these risks. To evaluate the efficacy and safety of primary G-CSF prophylaxis in patients with invasive breast cancer undergoing chemotherapy.
    METHODS: A systematic literature review was conducted according to the \"Minds Handbook for Clinical Practice Guideline Development\" using PubMed, Ichushi-Web, and the Cochrane Library databases. Randomized controlled trials (RCTs) and cohort studies assessing using G-CSF as primary prophylaxis in invasive breast cancer were included. The primary outcomes were overall survival (OS) and FN incidence. Meta-analyses were performed for outcomes with sufficient data.
    RESULTS: Eight RCTs were included in the qualitative analysis, and five RCTs were meta-analyzed for FN incidence. The meta-analysis showed a significant reduction in FN incidence with primary G-CSF prophylaxis (risk difference [RD] = 0.22, 95% CI: 0.01-0.43, p = 0.04). Evidence for improvement in OS with G-CSF was inconclusive. Four RCTs suggested a tendency for increased pain with G-CSF, but statistical significance was not reported.
    CONCLUSIONS: Primary prophylactic use of G-CSF is strongly recommended for breast cancer patients undergoing chemotherapy, as it has been shown to reduce the incidence of FN. While the impact on OS is unclear, the benefits of reducing FN are considered to outweigh the potential harm of increased pain.

    OBJECTIVE: to assess the effects of advanced wound dressings (AWD) commonly used in the treatment of predominantly neuropathic diabetic foot ulcers (DFU) The present meta-analysis was designed to support the development of the Italian Guidelines for the Treatment of Diabetic Foot Syndrome (DFS).
    METHODS: A Medline and Embase search were performed up to April 1st, 2024 collecting all RCTs including diabetic patients or reporting subgroup analyses on diabetic patients with DFU comparing AWD with placebo/standard of care (SoC), with a duration of at least 12 weeks. Prespecified endpoints were: ulcer healing (principal), time-to-healing, frequency of dressings change, major and minor amputation, pain, and all-cause mortality. AWD assessed were: alginates; foam, hydrocolloids, hydrogels, hyaluronic acid, hemoglobin spray, silver-impregnated, sucrose octasulfate-impregnated, honey-impregnated, micro-organism-binding, and protease-modulating matrix dressings. Mantel-Haenzel Odds ratios and 95% confidence intervals (MH-OR, 95% CIs) were either calculated or extracted directly from the publications. Weighted mean differences (WMD) and 95% CIs were calculated for continuous variables.
    RESULTS: Fifteen studies fulfilled all inclusion criteria. Participants treated with AWD had a significantly higher ulcer healing rate and shorter time-to-healing in comparison with SoC/placebo (MH-OR 1.50 [0.80, 2.79], p = 0.20 and WMD:: - 24.38 [- 42.90, - 5.86] days, p = 0.010). No other significant effect on the above reported prespecified endpoints were observed. For the primary endpoint, the quality of evidence was rated as \"moderate\".
    CONCLUSIONS: In conclusion, AWD, particularly sucrose-octasulfate, hydrogels, hyaluronic acid, and honey dressings, can actively promote wound healing and shortening time-to-healing in patients with DFU.

    目的:更新疾病缓解抗风湿药(DMARDs)疗效和安全性的证据,并为2024年日本风湿病学会(JCR)类风湿关节炎(RA)临床实践指南(CPG)更新的工作组提供信息。
    方法:我们在各种数据库中搜索了截至2022年6月发表的关于RA的随机对照试验,没有语言限制。对于15个临床问题中的每一个,两名独立审稿人筛选了这些文章,评估了核心成果,并进行了荟萃分析。
    结果:皮下注射甲氨蝶呤(MTX)在MTX初治RA患者中显示出与口服MTX相似的疗效。在对csDMARD反应不足(IR)的RA患者中,与安慰剂相比,Ozoralizumab联合MTX提高了药物疗效。在bDMARD-IRRA患者中,利妥昔单抗伴和不伴CSDMARD的疗效与其他bDMARD相似。与MTX-IRRA患者的肿瘤坏死因子抑制剂相比,联合Janus激酶抑制剂和MTX在4年内实现了相似的临床反应和同等的安全性。生物仿制药在csDMARD-IR和bDMARD-IRRA患者中的疗效与原始bDMARD相当。
    结论:本系统评价为2024年RA管理JCRCPG更新提供了最新证据。
    OBJECTIVE: To update evidence on the efficacy and safety of disease-modifying antirheumatic drugs (DMARDs) and provide information to the taskforce for the 2024 update of the Japan College of Rheumatology (JCR) clinical practice guidelines (CPG) for the management of rheumatoid arthritis (RA).
    METHODS: We searched various databases for randomised controlled trials on RA published until June 2022, with no language restriction. For each of the 15 clinical questions, 2 independent reviewers screened the articles, evaluated the core outcomes, and performed meta-analyses.
    RESULTS: Subcutaneous injection of methotrexate (MTX) showed similar efficacy to oral MTX in MTX-naïve RA patients. Ozoralizumab combined with MTX improved drug efficacy compared to the placebo in RA patients with inadequate response (IR) to csDMARD. Rituximab with and without concomitant csDMARDs showed similar efficacy to other bDMARDs in bDMARD-IR RA patients. Combined Janus kinase inhibitors and MTX achieved similar clinical responses and equal safety during a 4-year period compared to tumour necrosis factor inhibitors in MTX-IR RA patients. Biosimilars showed efficacy equivalent to that of the original bDMARDs in csDMARD-IR and bDMARD-IR RA patients.
    CONCLUSIONS: This systematic review provides latest evidence for the 2024 update of the JCR CPG for RA management.

    背景:该指南由意大利全科医生-初级保健和老年病医院-社区协会推广,并由国家卫生研究院和一个专家小组参与,其中包括来自25个科学和卫生专业组织的代表。该指南的目的是制定基于证据的建议,以评估不同临床环境中老年人的CGA疗效以及基于CGA的工具评估预后的准确性和实用性。
    方法:根据意大利国家指南和NICE标准体系(英国国家健康与护理卓越研究所)的方法手册,该指南是根据建议评估的分级制定的,发展和评价。最初选择了通过数据库搜索收集的20,000多个记录。根据117项符合纳入标准并在一般实践和初级保健中进行的研究(包括26项研究),确定了16项关于CGA疗效的建议。医疗和外科诊所(16项研究),急诊科(17项研究),医院内科和外科病房(53项研究),长期护理设施和疗养院(5项研究),临终关怀和姑息治疗网络(无研究)。关于基于CGA的预后工具的9项建议是基于42项在一般实践和初级保健中进行的研究(5项研究)的问题,医疗和外科诊所(4项研究),和医院病房(33项研究)。
    结果:使用CGA可以减少住院,死亡率,制度化,谵妄的风险,提高药物处方的适当性,并在不同环境下维持功能活动。进一步研究CGA在康复设施中的功效,疗养院,和临终关怀和姑息治疗设置建议。基于CGA的工具,特别是多维预后指数,应该用来预测不同环境下的一些负面结果。
    结论:本指南在临床实践中可能是有用的,并且可以作为支持在老年人中使用CGA研究的工具。
    BACKGROUND: The guideline was promoted by the Italian General Practitioners-Primary Care and Geriatrics Hospital-Community Societies and was carried out involving the National Institute of Health and an Expert Panel including representatives from 25 Scientific and Health-Professional Organizations. The aim of the Guideline was to develop evidence-based recommendations on the efficacy of CGA in older people across different clinical settings and the accuracy and utility of CGA-based tools to assess prognosis.
    METHODS: According to the methodological handbook of the Italian National System of Guidelines and NICE criteria (National Institute for Health and Care Excellence in England), the Guideline was produced based on the Grading of Recommendations Assessment, Development and Evaluation. Over 20,000 records gathered through databases searches were initially selected. Sixteen recommendations on CGA efficacy were defined based on 117 studies that met the inclusion criteria and were performed in general practices and primary care (26 studies included), medical and surgical clinics (16 studies), emergency departments (17 studies), hospital medical and surgical wards (53 studies), long-term care facilities and nursing homes (5 studies), hospices and palliative care networks (no studies). Nine recommendations on CGA-based prognostic tools were issues based on 42 included studies carried out in general practices and primary care (5 studies), medical and surgical clinics (4 studies), and hospital wards (33 studies).
    RESULTS: Using CGA can be useful to reduce hospitalization, mortality, institutionalization, the risk of delirium, and improve appropriateness in drug prescription and maintain functional activities in different settings. Further research on the efficacy of CGA in rehabilitative facilities, nursing homes, and hospice and palliative-care settings is recommended. CGA-based tools, particularly the Multidimensional Prognostic Index, should be used to predict some negative outcomes in different settings.
    CONCLUSIONS: This Guideline may be useful in clinical practice and as a tool to support research on the use of CGA in older people.

    背景:复发性或难治性急性髓性白血病(AML)的预后仍然很差。尽管已经研究了同时使用粒细胞集落刺激因子(G-CSF)和抗化学治疗剂以改善对AML的抗白血病作用,它的有用性仍然存在争议。本研究旨在探讨G-CSF引发作为缓解诱导治疗或挽救性化疗的效果。
    方法:我们使用PubMed对与G-CSF启动效应相关的研究进行了全面的文献搜索,Ichushi-Web,还有Cochrane图书馆.对汇总数据进行了定性分析,计算并总结风险比(RR)和置信区间(CI)。
    结果:两名评审员独立提取并访问了初步筛选过程中确定的278条记录,对62篇全文文章进行了第二次筛查的合格性评估.11项研究纳入定性分析,10项纳入荟萃分析。一项系统评价显示,用G-CSF启动与应答率和总生存率(OS)的改善无关。荟萃分析的结果表明,G-CSF启动组的复发率较低,没有研究间异质性[RR,0.91(95%CI0.82-1.01),p=0.08;I2=4%,p=0.35]。在特定人群中,包括具有中等细胞遗传学风险的患者和接受高剂量阿糖胞苷的患者,G-CSF启动方案延长OS。
    结论:G-CSF启动联合强化缓解诱导治疗在AML患者中并不普遍有效。需要进一步的研究来确定推荐G-CSF引发的患者队列。
    BACKGROUND: The outcomes of relapsed or refractory acute myeloid leukemia (AML) remain poor. Although the concomitant use of granulocyte colony-stimulating factor (G-CSF) and anti-chemotherapeutic agents has been investigated to improve the antileukemic effect on AML, its usefulness remains controversial. This study aimed to investigate the effects of G-CSF priming as a remission induction therapy or salvage chemotherapy.
    METHODS: We performed a thorough literature search for studies related to the priming effect of G-CSF using PubMed, Ichushi-Web, and the Cochrane Library. A qualitative analysis of the pooled data was performed, and risk ratios (RRs) with confidence intervals (CIs) were calculated and summarized.
    RESULTS: Two reviewers independently extracted and accessed the 278 records identified during the initial screening, and 62 full-text articles were assessed for eligibility in second screening. Eleven studies were included in the qualitative analysis and 10 in the meta-analysis. A systematic review revealed that priming with G-CSF did not correlate with an improvement in response rate and overall survival (OS). The result of the meta-analysis revealed the tendency for lower relapse rate in the G-CSF priming groups without inter-study heterogeneity [RR, 0.91 (95% CI 0.82-1.01), p = 0.08; I2 = 4%, p = 0.35]. In specific populations, including patients with intermediate cytogenetic risk and those receiving high-dose cytarabine, the G-CSF priming regimen prolonged OS.
    CONCLUSIONS: G-CSF priming in combination with intensive remission induction treatment is not universally effective in patients with AML. Further studies are required to identify the patient cohort for which G-CSF priming is recommended.
