    患有精神分裂症和双相情感障碍的人患躯体疾病的风险增加。这部分是由于缺乏体力活动,这可能源于童年。睡眠障碍与精神分裂症和双相情感障碍有关。我们旨在评估精神分裂症或双相情感障碍家族高风险儿童的身体活动和睡眠以及基于人群的控制。
    本研究是丹麦高风险和弹性研究的一部分-VIA11。父母所生的11岁儿童患有精神分裂症(FHR-SZ)(N=133),双相情感障碍(FHR-BP)(N=84),或对照(C)(N=150)通过加速度测定法平均6.9天进行评估。
    与对照组相比,FHR-SZ和FHR-BP的儿童高强度体力活动明显较低,(FHR-SZ每天平均小时数:0.29,SD0.19,FHR-BP每天平均小时数:0.27,SD0.24,对照0.38,SD0.22,P=<.001)。两组之间的睡眠没有差异。
    与对照组相比,FHR-SZ或FHR-BP的儿童体力活动较少。我们的研究强调了一个研究领域,该领域揭示了精神分裂症或躁郁症父母所生的迄今为止尚未探索的缺点。需要进一步的研究,以更好地理解FHR-SZ和FHR-BP儿童体力活动减少的因果途径和后果。
    UNASSIGNED: People with schizophrenia and bipolar disorder are at increased risk of having comorbid somatic illness. This is partly due to lack of physical activity, which may originate from childhood. Sleep disturbances are associated with schizophrenia and bipolar disorder. We aimed to assess physical activity and sleep in children at familial high risk of schizophrenia or bipolar disorder and population-based controls.
    UNASSIGNED: This study is part of The Danish High Risk and Resilience Study-VIA 11. Children aged 11 born to parents with schizophrenia (FHR-SZ) (N = 133), bipolar disorder (FHR-BP) (N = 84), or controls (C) (N = 150) were assessed by accelerometry for an average of 6.9 days.
    UNASSIGNED: High-intensity physical activity was significantly lower in children at FHR-SZ and FHR-BP compared to controls, (mean hours per day for FHR-SZ: 0.29, SD 0.19, for FHR-BP: 0.27, SD 0.24, and for controls 0.38, SD 0.22, P = <.001). Sleep did not differ between the groups.
    UNASSIGNED: Children at FHR-SZ or FHR-BP had less physical activity compared to controls. Our study highlights a research area that reveals a hitherto unexplored disadvantage of being born to parents with schizophrenia or bipolar disorder. Further research is needed to enhance better understanding of causal pathways and consequences of reduced physical activity in children with FHR-SZ and FHR-BP.

    背景:公布了图像定义的危险因素(IDRFs),用于预测神经母细胞瘤(NB)儿童完全切除原发性肿瘤的可行性和安全性。关于单个IDRF对原发肿瘤可切除性或患者预后的影响的理解有限。询问了高风险NB患者的多中心数据库以回答此问题。
    方法:高危NB患者(年龄<20岁)如果在切除前至少进行两次横断面成像,则符合资格。记录每个成像研究的IDRF和原发性肿瘤测量值。根据手术报告确定切除程度。
    结果:229例诊断为IDRF的患者中有211例,171名IDRFs患者在手术前。在没有肿瘤侵入或包裹肝门的情况下,切除≥90%的可能性更大。肝十二指肠韧带,肠系膜上动脉(SMA),肾蒂,腹主动脉/下腔静脉(IVC),髂血管,和/或诊断时的隔膜或手术前的IDRF重叠子集(隔膜除外)。当患者在诊断或术前根据是否存在任何IDRF进行分层时,无事件生存率(EFS)和总生存率(OS)没有显着差异。
    结论:诊断时或诱导化疗后存在的两个不同但重叠的IDRFs亚群显著影响高危NB患儿完全切除的概率。在该队列中,IDRFs的存在与OS或EFS的显着差异无关。
    BACKGROUND: Image-defined risk factors (IDRFs) were promulgated for predicting the feasibility and safety of complete primary tumor resection in children with neuroblastoma (NB). There is limited understanding of the impact of individual IDRFs on resectability of the primary tumor or patient outcomes. A multicenter database of patients with high-risk NB was interrogated to answer this question.
    METHODS: Patients with high-risk NB (age <20 years) were eligible if cross-sectional imaging was performed at least twice prior to resection. IDRFs and primary tumor measurements were recorded for each imaging study. Extent of resection was determined from operative reports.
    RESULTS: There were 211 of 229 patients with IDRFs at diagnosis, and 171 patients with IDRFs present pre-surgery. A ≥90% resection was significantly more likely in the absence of tumor invading or encasing the porta hepatis, hepatoduodenal ligament, superior mesenteric artery (SMA), renal pedicles, abdominal aorta/inferior vena cava (IVC), iliac vessels, and/or diaphragm at diagnosis or an overlapping subset of IDRFs (except diaphragm) at pre-surgery. There were no significant differences in event-free survival (EFS) and overall survival (OS) when patients were stratified by the presence versus absence of any IDRF either at diagnosis or pre-surgery.
    CONCLUSIONS: Two distinct but overlapping subsets of IDRFs present either at diagnosis or after induction chemotherapy significantly influence the probability of a complete resection in children with high-risk NB. The presence of IDRFs was not associated with significant differences in OS or EFS in this cohort.

    目标:我们的医疗中心实施了一个多学科团队,以改善高危老年人的手术决策。为了使这成为一个以病人为中心的过程,试点项目将患者及其家属/护理人员纳入这些对话.我们的假设是,多学科团队讨论可以改善艰难的手术决策。方法:从2022年1月至6月,我们在退伍军人事务医疗中心为患者及其家人提供了多学科讨论的参与。会议后1-6天进行了半结构化访谈。采用定性混合方法对访谈笔录进行分析。结果:六名患者和护理人员参加了访谈。他们发现讨论有助于提高他们对手术决定的理解。在这些中,50%(6个中的3个)的患者根据讨论改变了对计划手术的决定。结论:在多学科手术决策讨论中包括患者和护理人员,导致一半的患者改变手术计划。这项试点研究证明了所有参与者的接受度和可行性。
    Objective: Our medical center implemented a multidisciplinary team to improve surgical decision making for high-risk older adults. To make this a patient-centric process, a pilot program included the patient and their family/caregiver(s) in these conversations. Our hypothesis is that multidisciplinary team discussions can improve difficult surgical decision making. Methods: From January to June 2022, we offered patients and their family participation in multidisciplinary discussions at a Veterans Affairs medical center. Semistructured interviews were conducted 1-6 days after the meeting. Interview transcripts were analyzed with qualitative mixed-methods approach. Results: Six patients and caregivers participated in the interviews. They found the discussion helpful for improving their understanding of the surgical decision. Out of these, 50% (3 of 6) of the patients changed their decision regarding the planned operation based on the discussion. Conclusion: Including patients and caregiver(s) in multidisciplinary surgical decision-making discussions resulted in half of the patients changing their surgical plans. This pilot study demonstrated both acceptance and feasibility for all participants.

    背景:高剂量化疗和自体干细胞移植(HDCT/auto-SCT)和131I-间碘苄基胍(131I-MIBG)治疗在高危神经母细胞瘤中显示出积极的结果。然而,仍需要更优化的治疗策略。
    方法:NB-2014研究是非随机的,前瞻性试验检查转移性高危神经母细胞瘤患者使用响应适应巩固治疗的生存结局。我们使用转移部位的诱导后残留123I-MIBG状态作为治疗反应标记。在转移部位实现MIBG摄取完全消退的患者经历了减少的第一次HDCT/auto-SCT,HDCT剂量减少20%。在第一次HDCT/自动SCT之后,MIBG摄取剩余的患者接受剂量递增(18mCi/kg)131I-MIBG治疗.相比之下,转移部位MIBG完全消退的患者接受标准剂量(12mCi/kg)的131I-MIBG.我们将生存和毒性结果与NB-2009的历史对照组进行了比较。
    结果:在接受治疗的65例患者中,63%的人在诱导化疗后转移部位获得MIBG摄取的完全缓解,而29%的患者在首次HDCT/auto-SCT后仍在转移部位摄取MIBG。3年无事件生存率(EFS)和总生存率(OS)分别为68.2%±6.0%和86.5%±4.5%,分别。与NB-2009相比,EFS相似(p=.855);然而,NB-2014具有更高的OS(p=.031),治疗相关死亡率的累积发生率较低(p=.036),和较少的急性和晚期毒性。
    结论:我们的结果表明,基于转移部位化疗反应的反应适应性巩固治疗有利于更好的治疗剪裁,对于转移性高危神经母细胞瘤患者似乎很有希望。
    BACKGROUND: Tandem high-dose chemotherapy and autologous stem cell transplantation (HDCT/auto-SCT) and incorporation of 131I-metaiodobenzylguanidine (131I-MIBG) treatment have shown positive outcomes in high-risk neuroblastoma. However, more optimized treatment strategies are still needed.
    METHODS: The NB-2014 study was a nonrandomized, prospective trial that examined survival outcomes in metastatic high-risk neuroblastoma patients using response-adapted consolidation therapy. We used post-induction residual 123I-MIBG status at metastatic sites as a treatment response marker. Patients achieving complete resolution of MIBG uptake at metastatic sites underwent a reduced first HDCT/auto-SCT with a 20% dose reduction in HDCT. After the first HDCT/auto-SCT, patients with remaining MIBG uptake received dose-escalated (18 mCi/kg) 131I-MIBG treatment. In contrast, those with complete resolution of MIBG at metastatic sites received a standard dose (12 mCi/kg) of 131I-MIBG. We compared survival and toxicity outcomes with a historical control group from the NB-2009.
    RESULTS: Of 65 patients treated, 63% achieved complete resolution of MIBG uptake at metastatic sites following induction chemotherapy, while 29% of patients still had MIBG uptake at metastatic sites after the first HDCT/auto-SCT. The 3-year event-free survival (EFS) and overall survival (OS) rates were 68.2% ± 6.0% and 86.5% ± 4.5%, respectively. Compared to NB-2009, EFS was similar (p = .855); however, NB-2014 had a higher OS (p = .031), a lower cumulative incidence of treatment-related mortality (p = .036), and fewer acute and late toxicities.
    CONCLUSIONS: Our results suggest that response-adaptive consolidation therapy based on chemotherapy response at metastatic sites facilitates better treatment tailoring, and appears promising for patients with metastatic high-risk neuroblastoma.

    印度的2021年结核病(TB)预防性治疗指南将矽肺作为筛查组,然而,对暴露于二氧化硅粉尘的个体的潜伏性结核感染(LTBI)检测没有得到充分重视.关注估计有5200万接触二氧化硅粉尘的工人,尤其是Khambhat的玛瑙石工人,古吉拉特邦,我们的研究旨在估计LTBI的患病率,确定预测因子,并收集结核病和矽肺病专家的见解。采用顺序解释性混合方法方法,一项横断面研究涉及Khambhat的463名年龄≥20岁的玛瑙石工人,使用IGRA试剂盒进行LTBI测试。与专家的深入访谈补充了定量发现。在玛瑙石工人中,58%的LTBI检测呈阳性,预测因素包括更长的暴露,工作类型,和BCG疫苗接种。我们的研究结果表明,与普通人群相比,LTBI的负担几乎是两倍,特别是在接触二氧化硅粉尘较高的职业中。专家主张将暴露于二氧化硅粉尘的个人纳入高危人群进行LTBI测试,探索具有成本效益的替代方案,如改善皮肤敏感性测试,和更短的结核病预防治疗方案,以提高依从性。未来的研究应该探索对LTBI高患病率和最佳暴露持续时间的二氧化硅粉尘暴露个体的预先结核病预防性治疗。这项研究强调了在暴露于二氧化硅粉尘的人群中,迫切需要政策变化和创新方法来预防结核病。影响全球职业卫生战略。
    The 2021 tuberculosis (TB) preventive treatment guidelines in India included silicosis as a screening group, yet latent TB infection (LTBI) testing for silica-dust-exposed individuals is underemphasized. Focusing on an estimated 52 million silica-dust-exposed workers, particularly agate-stone workers in Khambhat, Gujarat, our study aims to estimate LTBI prevalence, identify predictors, and gather insights from TB and silicosis experts. Employing a sequential explanatory mixed-methods approach, a cross-sectional study involved 463 agate-stone workers aged ≥ 20 years in Khambhat, using IGRA kits for LTBI testing. In-depth interviews with experts complemented quantitative findings. Among agate-stone workers, 58% tested positive for LTBI, with predictors including longer exposure, type of work, and BCG vaccination. Our findings reveal a nearly double burden of LTBI compared to the general population, particularly in occupations with higher silica dust exposure. Experts advocate for including silica-dust-exposed individuals in high-risk groups for LTBI testing, exploring cost-effective alternatives like improved skin sensitivity tests, and shorter TB preventive treatment regimens to enhance compliance. Future research should explore upfront TB preventive treatment for silica-dust-exposed individuals with high LTBI prevalence and optimal exposure duration. This study underscores the urgent need for policy changes and innovative approaches to TB prevention among silica-dust-exposed populations, impacting global occupational health strategies.

    目的:EVEREST是一项针对肾细胞癌(RCC)患者的3期试验,这些患者在肾切除术后复发风险中等-高或极高,随机接受依维莫司辅助治疗或安慰剂治疗。使用依维莫司观察到更长的无复发生存期(RFS)(风险比[HR]0.85,95%置信区间[CI]0.72-1.00;p=0.051),但未达到名义显著性水平(p=0.044)。为了将这些结果与舒尼替尼和派姆单抗辅助治疗的阳性3期试验联系起来,我们在具有非常高危疾病和透明细胞组织学的类似EVEREST患者人群中进行了二次分析.
    方法:具有任何透明细胞成分和非常高风险疾病的肾切除术后患者,定义为pT3a(3-4级),pT3b-c(任何等级),T4(任何等级),或节点正状态(N+),已确定。使用按性能状态分层的Cox回归模型来比较治疗组之间的RFS和总生存期(OS)。
    在1499名患者中,717有透明细胞组织学和非常高风险的疾病;699符合资格标准,其中348人被随机分配到依维莫司手臂,和351到安慰剂组。两臂之间的患者特征相似。依维莫司组中只有163/348(47%)患者按计划完成了所有治疗,安慰剂组的225/351(64%)。依维莫司佐剂导致RFS的统计学显着改善(HR0.80;95CI0.65-0.99,p=0.041)。未发现生存获益的证据(HR0.85;95CI0.64-1.14,p=0.3)结论和临床意义:在复发风险非常高的透明细胞RCC患者中,与安慰剂相比,依维莫司佐剂导致RFS显著改善,但由于不良事件导致高停药率.尽管OS的治疗HR与RFS结果一致,没有达到统计学意义。重点关注风险分层工具和/或生物标志物,以最大程度地减少那些不太可能受益的人的毒性风险,这些信息有助于为高危肾细胞癌患者未来辅助试验的设计提供参考摘要:我们评估了在手术切除透明细胞肾癌后使用依维莫司与安慰剂相比的治疗复发风险非常高.我们发现,依维莫司治疗的患者的生存结果更好,尽管这些患者的副作用发生率较高。
    OBJECTIVE: EVEREST is a phase 3 trial in patients with renal cell cancer (RCC) at intermediate-high or very high risk of recurrence after nephrectomy who were randomized to receive adjuvant everolimus or placebo. Longer recurrence-free survival (RFS) was observed with everolimus (hazard ratio [HR] 0.85, 95% confidence interval [CI] 0.72-1.00; p = 0.051), but the nominal significance level (p = 0.044) was not reached. To contextualize these results with positive phase 3 trials of adjuvant sunitinib and pembrolizumab, we conducted a secondary analysis in a similar population of EVEREST patients with very high-risk disease and clear cell histology.
    METHODS: Postnephrectomy patients with any clear cell component and very high-risk disease, defined as pT3a (grade 3-4), pT3b-c (any grade), T4 (any grade), or node-positive status (N+), were identified. A Cox regression model stratified by performance status was used to compare RFS and overall survival (OS) between the treatment arms.
    UNASSIGNED: Of 1499 patients, 717 had clear cell histology and very high-risk disease; 699 met the eligibility criteria, of whom 348 were randomized to everolimus arm, and 351 to the placebo arm. Patient characteristics were similar between the arms. Only 163/348 (47%) patients in the everolimus arm completed all treatment as planned, versus 225/351 (64%) in the placebo arm. Adjuvant everolimus resulted in a statistically significant improvement in RFS (HR 0.80; 95%CI 0.65-0.99, p = 0.041). Evidence of a survival benefit was not seen (HR 0.85; 95%CI 0.64-1.14, p = 0.3) CONCLUSIONS AND CLINICAL IMPLICATIONS: In patients with clear cell RCC at very high-risk for recurrence, adjuvant everolimus resulted in significantly improved RFS compared to placebo but resulted in a high discontinuation rate due to adverse events. Although the treatment HR for OS was consistent with RFS findings, it did not reach statistical significance. With a focus on risk stratification tools and/or biomarkers to minimize toxicity risk in those not likely to benefit, this information can help inform the design of future adjuvant trials in high-risk RCC PATIENT SUMMARY: We assessed treatment with everolimus in comparison to placebo after complete surgical removal of clear-cell kidney cancer at very high risk of recurrence. We found that survival outcomes were better for patients treated with everolimus, although these patients had a higher rate of side effects.

    尽管在印度法律上接受同性恋,它仍然是一个社会禁忌,导致同性恋男性面临各种挑战。这些挑战主要包括成瘾/药物使用以及不一致和/或不正确的避孕套使用等问题,这些问题增加了获得性传播感染(STIs)和艾滋病毒的风险。因此,进行这项研究的目的是研究同性恋男性的成瘾/吸毒和避孕套使用方式。
    这项研究是在非政府组织(NGO)的外展地点进行的。共有240人参加,由18-24岁的同性恋和双性恋男性组成,他们在大都市孟买居住至少1年,已注册。收集有关成瘾/药物使用和避孕套使用模式的数据,编译,输入到MicrosoftExcel中,随后使用SPSS进行了分析。
    在所有参与者中,171(71.2%)报告从事成瘾/吸毒,在这些参与者中,105(61.4%)在性接触之前从事酒精消费,以增强快感或延迟高潮。吸烟是最常见的成瘾类型。习惯性成瘾/吸毒之间存在统计学上的显着关联(P=0.0023),使用摇头丸/壮阳药(P=0.00654)和,参与者使用避孕套不一致和/或不正确。然而,仅在性接触前计划成瘾/药物使用未显示显著相关性(P=0.066).
    同性恋男性的习惯性成瘾/吸毒增加了不一致和/或不正确使用避孕套的可能性,从而提高获得性传播感染和艾滋病毒的风险。为了减轻这种风险,应在青春期开始针对成瘾/药物使用预防的干预措施,以便在生命的早期阶段解决这一问题.
    UNASSIGNED: Despite the legal acceptance of homosexuality in India, it remains a social taboo, resulting in various challenges being faced by homosexual males. These challenges mainly include issues such as addiction/drug use and inconsistent and/ or incorrect condom usage which increase the risk of acquiring sexually transmitted infections (STIs) and HIV among them. This study was thus conducted with the objective of studying the patterns of addiction/drug use and condom usage among homosexual males.
    UNASSIGNED: The study was conducted at outreach sites of a non-governmental organization (NGO). A total of 240 participants, consisting of homosexual and bisexual males aged 18-24 years who were residing in the metropolitan city of Mumbai for at least 1 year, were enrolled. Data about addiction/drug use and patterns of condom usage was collected, compiled, entered into Microsoft Excel, and subsequently analyzed using SPSS.
    UNASSIGNED: Out of the total participants, 171 (71.2%) reported engaging in addiction/drug use, Among those participants, 105 (61.4%) engaged in alcohol consumption prior to sexual contact to enhance pleasure or delay climax. Cigarette smoking was the most common type of addiction. Statistically significant association was found between habitual addiction/drug use (P=0.0023), use of ecstasy/aphrodisiac drugs (P=0.00654) and, inconsistent and/or incorrect condom use among the participants. However, planned addiction/drug use only before sexual contact did not show a significant association (P=0.066).
    UNASSIGNED: Habitual addiction/drug use among homosexual males increases the likelihood of engaging in inconsistent and/ or incorrect condom use, thereby elevating the risk of acquiring STIs and HIV. To mitigate this risk, interventions targeting addiction/ drug use prevention should be initiated during adolescence to address this issue at an earlier stage of life.

    目的:高危神经母细胞瘤患者的生存率是不可接受的。日本已经开发了一种时间强化治疗策略,即延迟局部治疗以控制全身性疾病。我们在全国范围内进行了一次,prospective,延迟局部治疗的单臂临床试验。这项研究评估了延迟手术以增加治疗强度的安全性和有效性。
    方法:2011年5月至2015年9月,75例高危神经母细胞瘤患者纳入本研究。延迟的局部治疗包括五个疗程的诱导化疗(顺铂,吡柔比星,长春新碱,和环磷酰胺)和清髓性高剂量化疗(美法仑,依托泊苷,和卡铂),随后通过手术和放疗进行局部肿瘤切除。主要终点是无进展生存期(PFS)。次要终点是总生存期(OS),响应率,不良事件,和手术并发症。
    结果:纳入75例患者,64个可评估(第3阶段,n=8;第4阶段,n=56)。估计的3年PFS和OS率(95%置信区间[CI])分别为44.4%[31.8%-56.3%]和80.7%[68.5%-88.5%]。具体而言。完成治疗方案后INRC的反应率为66%(42/64;95%CI:53%-77%;23CR[完全反应],10VGPR[非常好的部分响应],和九个公关[部分响应])。没有患者在方案治疗期间或完成后30天内死亡。4级不良反应,排除血液学不良反应,48%的患者发生[31/64;95%CI:36%-61%]。在25%的患者中观察到主要的手术并发症[13/51;95%CI:14%-40%]。
    结论:这项研究表明,延迟局部治疗是可行的,并显示出有希望的疗效,提示在对高危神经母细胞瘤的比较研究中,应进一步考虑这种治疗方法。
    OBJECTIVE: Survival rates of patients with high-risk neuroblastoma are unacceptable. A time-intensified treatment strategy with delayed local treatment to control systemic diseases has been developed in Japan. We conducted a nationwide, prospective, single-arm clinical trial with delayed local treatment. This study evaluated the safety and efficacy of delayed surgery to increase treatment intensity.
    METHODS: Seventy-five patients with high-risk neuroblastoma were enrolled in this study between May 2011 and September 2015. Delayed local treatment consisted of five courses of induction chemotherapy (cisplatin, pirarubicin, vincristine, and cyclophosphamide) and myeloablative high-dose chemotherapy (melphalan, etoposide, and carboplatin), followed by local tumor extirpation with surgery and irradiation. The primary endpoint was progression-free survival (PFS). The secondary endpoints were overall survival (OS), response rate, adverse events, and surgical complications.
    RESULTS: Seventy-five patients were enrolled, and 64 were evaluable (stage 3, n = 8; stage 4, n = 56). The estimated 3-year PFS and OS rates (95% confidence interval [CI]) were 44.4% [31.8%-56.3%] and 80.7% [68.5%-88.5%], resspectively. The response rate of INRC after completion of the treatment protocol was 66% (42/64; 95% CI: 53%-77%; 23 CR [complete response], 10 VGPR [very good partial response], and nine PR [partial response]). None of the patients died during the protocol treatment or within 30 days of completion. Grade 4 adverse effects, excluding hematological adverse effects, occurred in 48% of patients [31/64; 95% CI: 36%-61%]. Major Surgical complications were observed in 25% of patients [13/51; 95% CI: 14%-40%].
    CONCLUSIONS: This study indicates that delayed local treatment is feasible and shows promising efficacy, suggesting that this treatment should be considered further in a comparative study of high-risk neuroblastoma.

    目的:不准确的青霉素过敏标签(PAL)的巨大负担是抗菌药物耐药性的重要驱动因素。过敏专家不足和缺乏“护理点”测试放大了这一点。我们调查了非过敏医疗保健专业人员(HCPs)提供直接口服青霉素挑战(DPC)用于青霉素过敏去标记的可行性。
    方法:这项前瞻性观察性研究是在英格兰的三家医院进行的,涉及三种环境(急性医学,术前和血液学-肿瘤学)。对PAL患者进行筛查并分层为低风险/高风险。低风险患者(非免疫介导的症状,良性皮疹,耐受阿莫西林以来和家族史)接受了DPC。
    结果:筛选了N=2257个PAL,1054人符合条件;接近643人,373拒绝,270份同意,259份风险分层(低风险=155;高风险=104)。126例低危患者接受DPC,122(96.8%)被去标记,没有严重的过敏反应。从筛查到同意的转化率为12%[在急性和选择性设置中分别为3.3%和17.9%;在血液学-肿瘤学和手术前设置中,同意的赔率分别为3.42(p<0.001)和5.53(p<0.001)。研究进展失败的常见原因包括难以接触到患者,临床不稳定/医疗原因,缺乏同意的能力和心理因素。
    结论:DPC可以通过非过敏HCP递送。高比例的PAL患者在研究途径中没有进展。需要在护理途径的最佳点递送DPC的策略以增强摄取。选择性设置比DPC的急性设置提供更大的机会。DPC的安全性和简单性适合英国以外的医疗保健系统采用,包括在资源有限的设置中。

    OBJECTIVE: The huge burden of inaccurate penicillin allergy labels (PALs) is an important driver of antimicrobial resistance. This is magnified by insufficient allergy specialists and lack of \'point-of-care\' tests. We investigated the feasibility of non-allergy healthcare professionals (HCPs) delivering direct oral penicillin challenges (DPCs) for penicillin allergy de-labelling.
    METHODS: This prospective observational study was conducted in three hospitals in England across three settings (acute medical, pre-surgical and haematology-oncology). Patients with a PAL were screened and stratified as low risk/high risk. Low risk patients (non-immune mediated symptoms, benign rash, tolerated amoxicillin since and family history) underwent a DPC.
    RESULTS: N = 2257 PALs were screened, 1054 were eligible; 643 were approached, 373 declined, 270 consented and 259 risk stratified (low risk = 155; high risk = 104). One hundred and twenty-six low risk patients underwent DPC, 122 (96.8%) were de-labelled with no serious allergic reactions. Conversion rate from screening-to-consent was 12% [3.3% and 17.9% in acute and elective settings respectively; odds ratios for consent were 3.42 (p < 0.001) and 5.53 (p < 0.001) in haematology-oncology and pre-surgical setting respectively. Common reasons for failure to progress in the study included difficulty in reaching patients, clinical instability/medical reasons, lacking capacity to consent and psychological factors.
    CONCLUSIONS: DPCs can be delivered by non-allergy HCPs. A high proportion of patients with PALs did not progress in the study pathway. Strategies to deliver DPC at optimal points of the care pathway are needed to enhance uptake. Elective settings offer greater opportunities than acute settings for DPC. The safety and simplicity of DPCs lends itself to adoption by healthcare systems beyond the UK, including in resource-limited settings.
