Background/Objective:Neurofibromatosis type 1 (NF1) is a multisystem disorder that affects ~1/3000 newborns. Plexiform neurofibromas (PN) are present in about half of cases and can transform (lifetime risk of 8-13%) into malignant peripheral nerve sheath tumor (MPNST), a highly aggressive and metastatic sarcoma with poor survival. Unfortunately, there are currently no reliable biomarkers to identify PN at risk of undergoing malignant transformation. Our research has revealed that a subset of benign-appearing and atypical PN exhibit deregulated immune surveillance and T-cell infiltration that precede malignant transformation. In this study, we are analyzing tumor microenvironment and immune landscape in NF1-related tissue specimens to identify biomarkers of disease progression. To power these studies, this project focused on constructing a dataset of NF1-related samples to be analyzed. Methods:701 patients were identified via Cerner billing codes and pathology archives. De-identified clinical data, including presenting symptoms, relevant clinical history, pathology diagnoses, disease features, prior chemotherapeutics/radiation, prior gene profiling, and imaging features were collected. Results: We selected 86 patients with a total of 175 samples. 81% of patients had a clinical diagnosis of NF1, and 6% had a history of MPNST. Out of the 175 samples, 54 were in the head and neck, 42 in the thorax, 28 in the lower extremity, 27 in the upper extremity, 26 in the pelvis/abdomen, and 15 in the paraspinal region. The leading causes of procedures were pain (41%), growth (40%), and concern for malignancy (27%). The most common tissue diagnoses were neurofibroma (51.4%), PN (20%), and undefined-grade MPNST (11%). Out of the 46 MPNSTs, 30 were primary tumors, 4 metastases, and 12 local recurrences. Conclusion and Potential Impact:The results of this study will provide valuable insights to inform preclinical models of NF1-tumorigenesis to validate these findings and identify novel treatment approaches for individuals affected by these rare but devastating tumors.
背景/目的:神经纤维瘤病 1 型(NF1)是一种多系统疾病,约有 1/3000 名新生儿患病。丛状神经纤维瘤(PN)出现在约半数病例中,可转变为恶性周围神经鞘瘤(MPNST)(终生患病风险为 8-13%),这是一种侵袭性极强的转移性肉瘤,存活率极低。遗憾的是,目前还没有可靠的生物标志物来识别有恶性转化风险的周围神经鞘瘤。我们的研究发现,一部分良性和非典型 PN 在恶性转化前会出现免疫监视和 T 细胞浸润失调。在本研究中,我们正在分析 NF1 相关组织标本中的肿瘤微环境和免疫景观,以确定疾病进展的生物标志物。为了推动这些研究,本项目的重点是构建一个待分析的 NF1 相关样本数据集。方法:通过 Cerner 账单代码和病理档案确定了 701 名患者。收集了去身份化的临床数据,包括主要症状、相关临床病史、病理诊断、疾病特征、之前的化疗/放疗、之前的基因分析和成像特征。结果我们选取了 86 名患者,共 175 份样本。81%的患者临床诊断为 NF1,6%的患者有 MPNST 病史。在 175 份样本中,54 份在头颈部,42 份在胸部,28 份在下肢,27 份在上肢,26 份在骨盆/腹部,15 份在脊柱旁区域。手术的主要原因是疼痛(41%)、增生(40%)和担心恶性肿瘤(27%)。最常见的组织诊断是神经纤维瘤(51.4%)、PN(20%)和未确定等级的 MPNST(11%)。在 46 例 MPNST 中,30 例为原发性肿瘤,4 例为转移瘤,12 例为局部复发。结论和潜在影响:这项研究的结果将为NF1肿瘤发生的临床前模型提供有价值的见解,以验证这些发现,并为受这些罕见但破坏性肿瘤影响的患者确定新的治疗方法。

Abdominal aortic aneurysm (AAA) is a vascular disease process whereby the aorta expands to apoint where rupture may occur. This serious condition is diagnosed in approximately 200,000 people in the United States per year and accounts for over 15,000 deaths annually. The only medical intervention proven to reduce the risk of AAA rupture is surgical repair; however, such repair is associated with high risk of death, reduced quality of life, and high expense. AAA is caused by the weakening of the artery wall due to inflammation-induced destruction of its structural components. Our clinical data shows increased levels of circulating elastin degradation products in patients with AAA, especially smokers, compared to risk factor matched controls. This observation led us to hypothesize that an immune reaction to elastin fragments initiates the inflammatory cascade in the aorta that leads to AAA formation. To test this hypothesis, C57BL/6 mice were injected with poly(lactide-co-glycolide) nanoparticle-encapsulated IL-10 to induce immune tolerance or nanoparticle-encapsulated control ovalbumin. Injection of elastin fragments was performed 7 days later to induce an immune response. AAA of the infrarenal aorta was induced by topical application of elastase during laparotomy procedure 14 days after nanoparticle injection. Aorta diameter was measured 16 days post-operatively with Microfil. Immunologic changes were evaluated by cytokine analysis, Tr1/Th17 cell ratio inperipheral blood, and splenic Th17 and Tr1 response to elastin. Based on prior work, we expect that induction of elastin tolerance using poly(lactide-co-glycolide) nanoparticle-encapsulated IL-10 will suppress abdominal aortic aneurysm expansion and promote an anti-inflammatoryenvironment characterized by increased Tr1/Th17 cell ratio, increased levels of anti-inflammatory cytokines, and decreased pro-inflammatory cytokine expression.
腹主动脉瘤(AAA)是主动脉扩张到可能发生破裂的一种血管疾病。在美国,每年约有 20 万人被诊断出患有这种严重疾病,每年有超过 1.5 万人因此而死亡。经证实,唯一能降低 AAA 破裂风险的医疗干预措施是手术修补;然而,这种修补与高死亡风险、生活质量下降和高费用相关。AAA 是由于炎症引起的动脉结构成分破坏导致动脉壁变薄而引起的。我们的临床数据显示,与危险因素匹配的对照组相比,AAA 患者(尤其是吸烟者)循环中的弹性蛋白降解产物水平升高。根据这一观察结果,我们推测弹性蛋白碎片引起的免疫反应启动了主动脉的炎症级联反应,从而导致 AAA 的形成。为了验证这一假设,我们给 C57BL/6 小鼠注射了包裹 IL-10 的聚乳酸-共聚乙二醇纳米粒子以诱导免疫耐受,或注射了包裹卵清蛋白的纳米粒子对照组。7 天后注射弹性蛋白片段以诱导免疫反应。注射纳米颗粒 14 天后,在开腹手术中局部应用弹性蛋白酶诱导肾下主动脉 AAA。术后 16 天用 Microfil 测量主动脉直径。通过细胞因子分析、外周血中的 Tr1/Th17 细胞比率以及脾脏 Th17 和 Tr1 对弹性蛋白的反应来评估免疫学变化。根据之前的研究,我们预计使用包裹了 IL-10 的聚乳酸-聚乙二醇纳米粒子诱导弹性蛋白耐受性将抑制腹主动脉瘤的扩张,并促进以 Tr1/Th17 细胞比率升高、抗炎细胞因子水平升高和促炎细胞因子表达降低为特征的抗炎环境。

Analysis of Nutritional Composition and Glycemic Control in Patients with Gestational Diabetes Mellitus 妊娠糖尿病患者的营养成分和血糖控制分析
Pub Date : 2024-01-11 DOI: 10.18060/27732

Background:The association between meal content and glycemic control is not well-understood in pregnancy, limits our ability to counsel patients regarding the optimal diet. We therefore sought to evaluate the relationship between maternal dietary content and glycemic control. Methods:This is a secondary analysis of the GDM-MOMS study, which was a randomized controlled pilot trial that compared glycemic targets in 60 pregnant individuals with GDM and either overweight or obesity. During the pilot trial, participants wore a blinded continuous glucose monitor (CGM) for two five-day periods, with the first data collection between 12-32 weeks and the second data collection between 32-36 weeks. During the time that participants wore their CGM, they also collected 3-day food diaries with detailed information regarding intake and cooking technique. These food diaries are being entered into the Nutrition Data System for Research (NDSR) software, which analyzes nutritional composition for each meal. Glycemic control as assessed by CGM will then be assessed based on maternal nutritional intake. Results:The American Diabetes Association recommends a 2,000-calorie daily diet with a minimum of 175g of carbohydrates (with 35% of the total calories coming from carbohydrates), 71g of protein, and 28g of fat. Preliminary data extracted from NDSR includes nutritional analysis of 38 daily food diaries from 14 patients. 12/38 (31.6%) food logs show consumption of less than 35% of their total calories from carbohydrates, with the other 26 consuming 36-62%. Glycemic load can be used to assess how a patient’s diet affects their glycemic levels. 25/38 (65.8%) of food logs demonstrate a daily glycemic load (GL) of 100, with the other 13 showing daily GLs rangingfrom 108-252. Conclusions and Further Directions:Further analyses will assess post-meal glycemic response using both patient-monitored glucose values and reports from their CGM to determine which types of diets allow for optimal glycemic control.
背景:妊娠期膳食内容与血糖控制之间的关系尚不十分清楚,这限制了我们为患者提供最佳饮食建议的能力。因此,我们试图评估孕妇饮食内容与血糖控制之间的关系。方法:这是对 GDM-MOMS 研究的二次分析,该研究是一项随机对照试验,比较了 60 名患有 GDM 和超重或肥胖症的孕妇的血糖目标。在试点试验期间,参与者佩戴盲法连续血糖监测仪(CGM)进行了两次为期五天的测试,第一次数据收集时间为 12-32 周,第二次数据收集时间为 32-36 周。在佩戴 CGM 期间,参与者还收集了 3 天的食物日记,其中包含有关摄入量和烹饪技巧的详细信息。这些食物日记将被输入营养研究数据系统(NDSR)软件,该软件可分析每餐的营养成分。然后,将根据产妇的营养摄入量评估 CGM 评估的血糖控制情况。结果:美国糖尿病协会推荐的每日饮食热量为 2000 卡路里,其中碳水化合物至少为 175 克(总热量的 35% 来自碳水化合物)、蛋白质 71 克、脂肪 28 克。从 NDSR 中提取的初步数据包括对 14 名患者的 38 份每日饮食日记进行的营养分析。12/38(31.6%)份食物日志显示碳水化合物摄入量占总热量的比例低于 35%,其他 26 份食物日志显示碳水化合物摄入量占总热量的比例为 36-62%。血糖生成负荷可用于评估患者的饮食如何影响其血糖生成水平。25/38(65.8%)的食物日志显示每日血糖生成负荷 (GL) 为 100,其他 13 人显示每日血糖生成负荷为 108-252 不等。结论和进一步的研究方向:进一步的分析将使用患者监测的血糖值和 CGM 的报告来评估餐后血糖反应,以确定哪种类型的饮食可以实现最佳的血糖控制。

Background: Community health workers (CHWs) promote health education, address social determinants of health, and bridge the gap between healthcare systems and underserved populations, but the lack of sustainable funding remains a challenge to greater CHW utilization. Medicaid reimbursement has been identified as a promising mechanism to fund CHWs, however, state policies vary widely. A comparative policy analysis can guide future reimbursement strategies. Methods: We conducted a comparative policy analysis of Medicaid reimbursement for CHWs. State government websites and legal databases were searched utilizing keyword search terms related to CHWs and Medicaid reimbursement. We identified and analyzed relevant statutes, regulations, and administrative codes for reimbursement mechanism, rates, supervision, certification, and scope of practice. Results: 26 states currently reimburse CHWs through Medicaid; 3 states started reimbursement in the last six months. 16 states authorize payment through State Plan Amendments (SPAs), 3 use Section 1115 demonstration waivers, 10 use Medicaid managed care organization contracts, and 4 use blended strategies. 13 states require certification and supervision for reimbursement, although the supervising licensed professional can vary. The scope of practice of CHW also varies between states. There is a large range for reimbursement rates; for example, billing code 98960 currently used by 14 states varies from $9.70 in Indiana to $55.25 in Arizona for a 30 minute visit. Policy Implications: This study can inform sustainable reimbursement models through Medicaid for CHWs in Indiana and other states. An SPA may be the most expedient way for Indiana to increase reimbursement for CHWs, but its narrowness and inflexibility could hinder CHWs' positive impact. The variety of strategies currently in use demonstrates that there is no single path to sustainable financing. Protocols for a set of scoping reviews will result from this comparative analysis for more in-depth investigations of key peer-reviewed and grey literature.
背景:社区保健员(CHWs)促进健康教育,解决健康的社会决定因素,并在医疗保健系统和服务不足人群之间架起桥梁,但缺乏可持续的资金仍然是提高社区保健员利用率的一个挑战。医疗补助(Medicaid)报销已被确定为资助社区保健工作者的一种有前途的机制,但各州的政策差异很大。政策比较分析可为未来的报销策略提供指导。方法:我们对 CHW 的医疗补助报销政策进行了比较分析。我们使用与 CHWs 和 Medicaid 补偿相关的关键词搜索各州政府网站和法律数据库。我们确定并分析了有关报销机制、费率、监督、认证和执业范围的相关法规、条例和行政法规。结果:目前有 26 个州通过医疗补助计划为 CHWs 报销;3 个州在过去六个月内开始报销。16 个州通过州计划修正案 (SPA) 授权付款,3 个州使用第 1115 款示范豁免,10 个州使用医疗补助管理性护理组织合同,4 个州使用混合策略。13 个州要求获得认证和监督才能报销费用,但监督的持证专业人员可能有所不同。各州对社区保健工作者的执业范围也不尽相同。报销率的范围很大;例如,目前有 14 个州使用的计费代码 98960 从印第安纳州的 9.70 美元到亚利桑那州的 55.25 美元不等,每次就诊时间为 30 分钟。政策影响:这项研究可以为印第安纳州和其他州通过医疗补助为 CHWs 提供可持续的报销模式提供参考。对于印第安纳州来说,SPA 可能是增加对 CHWs 补偿的最快捷方式,但其狭隘性和不灵活性可能会阻碍 CHWs 的积极影响。目前正在使用的各种策略表明,可持续融资的途径并不单一。通过此次比较分析,我们将制定一套范围审查协议,以便对主要的同行评审文献和灰色文献进行更深入的调查。

Delayed Prescribing of Non-Vitamin K Antagonist Oral Anticoagulants (NOACs) in Patients with Low Socioeconomic Status 社会经济地位低的患者延迟服用非维生素 K 拮抗剂口服抗凝药 (NOAC)
Pub Date : 2024-01-11 DOI: 10.18060/27744

Background/Objective: Atrial fibrillation (AF) and venous thromboembolism (VTE) are conditions with significant morbidity and mortality when left untreated. American Heart Association guidelines changed in 2019 to make non-vitamin K antagonist oral anticoagulants (NOACs) the preferred method for preventing stroke and systemic embolism in patients with AF or history of VTE. NOACs were first introduced to the United States in 2010 and now include dabigatran, apixaban, rivaroxaban, and edoxaban. There is a dearth of research concerning the speed with which new treatments are prescribed to those in different socioeconomic status (SES) groups. We hypothesized that patients with lower SES were prescribed NOACs later than higher SES counterparts following the introduction of NOACs in 2010. Methods: The IU Cardiovascular Research Consortium/Sidus Dataset was mined for AF and VTE patients prescribed a NOAC between 2010 and 2022. The SES groups were determined using 2020 U.S. Census income data that correlated to patients’ zip codes. The yearly number ofpatients in each SES group were compared to assess for proportional uptake of NOAC prescribing. The primary outcome was the proportion of low SES to high SES prescribing over each year between 2010 and 2022. Results: Low SES patients (n=101,945) were prescribed NOACs at an average of 0.65 times the rate of high SES patients (n= 89,130) from 2010 to 2012, the first three years of NOAC market availability. Prescribing rates equilibrated in 2013 and low SES prescribing has outpaced high SES prescribing since 2021. Conclusion/Impact: Low SES patients experienced a three year delay in receiving NOAC prescriptions at the same rate as their high SES counterparts. Systemic changes, like more frequent prescribing guideline updates and improved evidence-based education amongst providers in low-income areas, could prevent a similar delay when introducing similarly transformative treatments in the future.
背景/目的:心房颤动(AF)和静脉血栓栓塞症(VTE)如不及时治疗,会导致严重的发病率和死亡率。美国心脏协会指南于 2019 年做出改变,将非维生素 K 拮抗剂口服抗凝药(NOAC)作为房颤或有 VTE 病史患者预防中风和全身性栓塞的首选方法。NOACs 于 2010 年首次引入美国,目前包括达比加群、阿哌沙班、利伐沙班和埃多沙班。关于不同社会经济地位(SES)群体接受新疗法的速度,目前还缺乏相关研究。我们假设,自 2010 年引入 NOACs 后,社会经济地位较低的患者获得 NOACs 处方的时间晚于社会经济地位较高的患者。研究方法从 IU Cardiovascular Research Consortium/Sidus Dataset 数据集中挖掘出 2010 年至 2022 年期间被处方 NOAC 的房颤和 VTE 患者。根据与患者邮政编码相关的 2020 年美国人口普查收入数据确定 SES 组别。对每个 SES 组别中每年的患者人数进行比较,以评估 NOAC 处方的使用比例。主要结果是 2010 年至 2022 年期间每年低 SES 与高 SES 的处方比例。结果2010 年至 2012 年,即 NOAC 上市的前三年,低 SES 患者(n=101,945)的 NOAC 处方率平均是高 SES 患者(n=89,130)的 0.65 倍。2013 年处方率趋于平衡,自 2021 年以来,低 SES 处方率超过了高 SES 处方率。结论/影响:低社会经济地位患者延迟三年接受 NOAC 处方的比例与高社会经济地位患者相同。系统性变革,如更频繁地更新处方指南和改善低收入地区医疗服务提供者的循证教育,可避免未来引入类似变革性治疗时出现类似的延迟。

Background and Hypothesis: Children with voiding dysfunction (VD), such as incontinence or urinary frequency, may report lower quality of life (QOL) compared to their peers. QOL questionnaires which could be used in this population have several limitations. PinQ is a bladder-specific, health-related QOL questionnaire, but it was developed without stakeholder input and fails to separate symptoms from QOL. Kidscreen-10 is a generic QOL questionnaire. We aimed to understand how QOL captured using existing instruments correlates with VD severity in a cross-sectional study. We hypothesized that large differences in symptoms would correspond with large differences in bladder-specific QOL but small differences in generic QOL. Methods: We recruited children 8-18 years old with VD at a pediatric urology clinic (June-July 2023). VD included daytime incontinence, enuresis, frequency, urgency, and dysuria. We excluded children with severe developmental delay, anatomical urological abnormalities, or history ofurologic surgery. We captured demographics, symptoms (Vancouver Dysfunction Voiding Symptom Score, DVSS), and QOL (PinQ and Kidscreen-10). Questionnaire scores were compared to weighted means from previous studies. We calculated Spearman correlations and QOL differences corresponding with the reported 20-point range of DVSS scores. Results: Twenty children (11 girls) at a median age of 10 years old participated (Table 1). Mean DVSS score was 14, similar to previous studies (weighted mean: 15). PinQ scores had a moderate positive correlation with DVSS scores (r = 0.37) with a 20-point DVSS difference  corresponding to a 24% difference in PinQ scores (Figure 1). Kidscreen-10 scores had a moderate negative correlation with DVSS scores (r = -0.33) with a 20-point DVSS difference corresponding to a 12% difference in Kidscreen-10 scores (Figure 2). Conclusions: Previously published QOL questionnaires have significant limitations, limiting their clinical use in the care of patients with VD. A new, patient-centered, highly specific, and sensitive healthrelated QOL questionnaire is needed.
背景与假设:与同龄人相比,患有尿失禁或尿频等排尿功能障碍(VD)的儿童的生活质量(QOL)可能较低。可用于此类人群的 QOL 问卷存在一些局限性。PinQ 是一种针对膀胱的、与健康相关的 QOL 问卷,但它在开发过程中并未征求利益相关者的意见,也未能将症状与 QOL 区分开来。Kidscreen-10 是一份通用的 QOL 问卷。我们的目的是在一项横断面研究中了解使用现有工具获得的 QOL 与 VD 严重程度的相关性。我们假设,症状的巨大差异会导致膀胱特异性 QOL 的巨大差异,但通用 QOL 的差异较小。研究方法我们在一家儿科泌尿科诊所招募了 8-18 岁患有 VD 的儿童(2023 年 6 月至 7 月)。尿失禁包括日间尿失禁、遗尿、尿频、尿急和排尿困难。我们排除了严重发育迟缓、泌尿系统解剖异常或有泌尿系统手术史的儿童。我们收集了人口统计学资料、症状(温哥华功能障碍排尿症状评分,DVSS)和 QOL(PinQ 和 Kidscreen-10)。问卷得分与以往研究的加权平均值进行了比较。我们计算了斯皮尔曼相关性以及与报告的 20 分 DVSS 评分范围相对应的 QOL 差异。结果:共有 20 名中位数年龄为 10 岁的儿童(11 名女孩)参加(表 1)。DVSS 平均分为 14 分,与之前的研究结果相似(加权平均分:15 分)。PinQ 分数与 DVSS 分数呈中度正相关(r = 0.37),20 分的 DVSS 差异对应于 24% 的 PinQ 分数差异(图 1)。Kidscreen-10 分数与 DVSS 分数呈中度负相关(r = -0.33),20 分的 DVSS 差异对应于 12% 的 Kidscreen-10 分数差异(图 2)。结论以前公布的 QOL 问卷有很大的局限性,限制了它们在 VD 患者护理中的临床应用。我们需要一种新的、以患者为中心的、高度特异性和敏感性的健康相关 QOL 问卷。

Background:Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus characterized by symptoms of esophageal dysfunction and 15 or more eosinophils per high-powered field (HPF) on esophageal biopsy. Treatment options for EoE include proton pump inhibitors (PPIs), topical corticosteroids (TCS), dietary elimination, and dupilumab. Dupilumab is monoclonal antibody against IL-4 and IL-13 administered subcutaneously and was granted FDA approval for EoE in adults and adolescents recently in 2022. Outcomes of real-world, clinical use of dupilumab for EoE remains unknown. Objectives:To observe outcomes in pediatric patients with EoE treated with dupilumab. Methods:A retrospective cohort study of pediatric patients prescribed dupilumab for EoE was conducted. Medical records were reviewed for demographic and clinical information as well as endoscopic and histologic findings before and after dupilumab treatment. Results:A total of 28 patients were included (mean age 15y, 71.4% male). Mean baseline maximum eosinophils/HPF was 48 ± 41. 75% of patients were treated with combination therapy of EoE with diet elimination, PPIs, or TCS prior to being prescribed dupilumab. Prior authorization for dupilumab was required in 85.7% of cases. Ten patients had follow-up endoscopy with biopsy after starting dupilumab, and among these patients the mean maximum eosinophils/HPF with dupilumab significantly improved from 44 ± 37 to 13 ± 15 (p=0.027). Among 12 patients who had follow up clinic visits, two patients reported pain or swelling at injection sites, but no otheradverse events were reported Conclusions:Dupilumab significantly improves histologic findings of EoE and is well tolerated among pediatric patients. We hope for continued monitoring of these patients to understand the clinical utility of dupilumab for EoE over time.
背景:嗜酸性粒细胞食管炎(EoE)是一种慢性食管炎症性疾病,以食管功能障碍症状和食管活检每高倍视野(HPF)15 个或更多嗜酸性粒细胞为特征。嗜酸性粒细胞增多症的治疗方法包括质子泵抑制剂(PPI)、局部皮质类固醇(TCS)、饮食调理和杜比单抗。杜比鲁单抗是一种针对IL-4和IL-13的单克隆抗体,可皮下注射,最近于2022年获得美国食品药品管理局(FDA)批准用于成人和青少年的EoE治疗。在现实世界中,临床使用杜比鲁单抗治疗咽喉炎的疗效尚不清楚。目的:观察使用杜比鲁单抗治疗的儿童咽喉炎患者的疗效。方法:对开具杜比单抗治疗咽喉炎的儿科患者进行回顾性队列研究。研究人员查阅了病历,以了解杜比鲁单抗治疗前后的人口统计学、临床信息以及内镜和组织学检查结果。结果:共纳入28名患者(平均年龄15岁,71.4%为男性)。平均基线最大嗜酸性粒细胞/HPF为48 ± 41。75%的患者在接受杜比鲁单抗治疗前接受了嗜酸性粒细胞饮食消除、PPIs或TCS联合治疗。85.7%的病例需要获得杜比鲁单抗的事先授权。10名患者在开始使用杜比鲁单抗后进行了随访内镜检查和活组织检查,在这些患者中,使用杜比鲁单抗后,平均最大嗜酸性粒细胞/HPF从44 ± 37明显降低至13 ± 15(P=0.027)。结论:杜匹单抗能明显改善咽喉炎的组织学检查结果,而且在儿童患者中耐受性良好。我们希望继续对这些患者进行监测,以了解杜匹单抗在治疗咽喉炎方面的临床效用。

Alzheimer's disease (AD), fracture healing, and the gut microbiome are interconnected aspects of health that have gained significant research interest. Recent studies suggest gut dysbiosis may play a role in AD pathogenesis, potentially through the gut-brain axis, a bidirectional communication system. Moreover, the gut microbiome's role in bone health could link dysbiosis and fracture risk. Furthermore, research reports have revealed that the brain communicates with bone, termed the bone-brain axis. Despite these insights, the effect of the gut microbiome on fracture healing in AD remains largely unexplored. To uncover these connections, our study uses the AD mouse models, 3xTg and 5xFAD. We conducted osteotomies on these mice and analyzed fecal samples that were collected at different timepoints. Fecal samples are being examined via qPCR and 16s RNA analysis toidentify and quantify bacterial phyla. These findings will be linked to both AD progression, gauged through behavior and histological analyses, and fracture healing, quantified using X-ray mRUST scoring, microCT, and histology. We hypothesize that the progression of AD could alter the gut microbiome, potentially affecting fracture healing. This might occur through inflammation pathways triggered by specific gut bacteria. We may identify specific gut bacteria that play critical roles in both fracture healing and AD. We anticipate finding a shift towards pro-inflammatory bacterial phyla in the context of AD progression and during the fracture healing process. If this hypothesis is validated, it could unlock new therapeutic strategies aimed at targeting the gut microbiome to improve bone health, fracture healing, and AD progression in patients.
阿尔茨海默病(AD)、骨折愈合和肠道微生物组是相互关联的健康问题,已引起了研究人员的极大兴趣。最近的研究表明,肠道菌群失调可能通过肠道-大脑轴这一双向交流系统在阿尔茨海默病发病机制中发挥作用。此外,肠道微生物组在骨骼健康中的作用可能将菌群失调与骨折风险联系起来。此外,研究报告还揭示了大脑与骨骼之间的沟通,即骨-脑轴。尽管有了这些见解,但肠道微生物组对艾滋病患者骨折愈合的影响在很大程度上仍未得到探讨。为了揭示这些联系,我们的研究使用了 AD 小鼠模型 3xTg 和 5xFAD。我们对这些小鼠进行了截骨手术,并分析了在不同时间点采集的粪便样本。粪便样本正在通过 qPCR 和 16s RNA 分析进行检验,以确定细菌门类并对其进行量化。这些发现将与注意力缺失症的进展(通过行为和组织学分析进行衡量)和骨折愈合(通过 X 射线 mRUST 评分、microCT 和组织学进行量化)相关联。我们假设,AD 的进展会改变肠道微生物群,从而可能影响骨折愈合。这可能是通过特定肠道细菌引发的炎症途径发生的。我们可能会找出在骨折愈合和 AD 中发挥关键作用的特定肠道细菌。我们预计,在 AD 发展过程中和骨折愈合过程中,会发现向促炎细菌门类的转变。如果这一假设得到验证,它将开启以肠道微生物组为靶点的新治疗策略,从而改善患者的骨骼健康、骨折愈合和 AD 进展。

Introduction: Rigid silicon electrodes like Utah array grids and Neuropixel probes have been used in human and animal brain models to understand the dynamics of neural computation, treat neurodegenerative disorders, and act as brain-machine-interfaces. However, when implanted chronically, glial proliferation can rapidly disrupt the interaction between neurons and electrodes, drastically reducing recording fidelity. The development of flexible electrodes has the potential to minimize tissue damage and inflammation, which allows for long-term recordings over several months. In line with this objective, the Nano-neurotechnology Lab at Purdue University has developed a 6-µm thick, flexible, and biocompatible Parylene probe to facilitate chronic recordings in awake mice. However, flexible electrodes present a unique engineering challenge as the force required to insert into the brain causes the probe to buckle and fail during insertion.  Methods and Results: Here, I designed a micropipette shuttle using a glass micropipette and custom insertion system which provided reproducible probe implantation into the cortex. The implantation device was designed in CAD software and 3D-printed for rapid prototyping. The procedure was developed on brain phantoms made of 0.6% agarose with a comparable Young’s modulus to mouse brain tissue. Utilizing 3D-printed pieces and the surface tension of diluted poly-vinyl-acrylate adhesive to align the probe to a micropipette, insertion of the electrode and retraction of the shuttle was accomplished in awake mice.   Conclusion: The implications of flexible recording electrodes are extensive. Long-term implantation opens the door for understanding behavioral and learning dynamics over time. Moreover, the flexibility of these probes allows for the combination of 2-photon optical microscopy, thus enabling multi-modal investigation of neuronal physiology. A low-cost, consistent procedure is the first step in the implementation of these flexible probes for further advancements in fundamental neuroscience research and its potential applications in human and animal studies. 
简介犹他阵列网格和神经像素探针等刚性硅电极已被用于人类和动物大脑模型,以了解神经计算的动态、治疗神经退行性疾病,并用作脑-机接口。然而,当长期植入电极时,胶质增生会迅速破坏神经元与电极之间的相互作用,从而大大降低记录的保真度。柔性电极的开发有可能最大限度地减少组织损伤和炎症,从而实现几个月的长期记录。为了实现这一目标,普渡大学纳米神经技术实验室开发了一种 6 微米厚、柔韧、生物相容性好的 Parylene 探针,以方便对清醒小鼠进行长期记录。然而,柔性电极带来了独特的工程挑战,因为插入大脑所需的力会导致探针在插入过程中弯曲和失效。 方法与结果在此,我设计了一种使用玻璃微量移液管和定制插入系统的微量移液管穿梭器,可将探针重复植入大脑皮层。该植入装置是在 CAD 软件中设计的,并通过 3D 打印实现了快速原型制作。该程序是在由 0.6% 琼脂糖制成的脑模型上开发的,其杨氏模量与小鼠脑组织相当。利用三维打印件和稀释的聚丙烯酸乙烯酯粘合剂的表面张力将探针对准微量移液管,在清醒的小鼠体内完成了电极的插入和梭子的回缩。 结论柔性记录电极具有广泛的意义。长期植入为了解行为和学习动态打开了大门。此外,这些探针的灵活性允许与双光子光学显微镜相结合,从而实现对神经元生理学的多模式研究。低成本、一致的程序是实施这些灵活探针的第一步,可进一步推动基础神经科学研究及其在人类和动物研究中的潜在应用。

Background and Objective:In the emergency department, providers are expected to evaluate patients who have experienced strangulation resulting from sexual assault or interpersonal violence. Non-fatal strangulation can lead to significant injuries, including carotid artery dissection. Given the prevalence of strangulation injuries, providers must feel confident in their decision-making for this population. Previous educational interventions effectively improved provider knowledge of sexual assault and domestic violence patients, however, no studies have been conducted with the goal of improving provider knowledge about strangulation injuries in this population. We aimed to assess and improve emergency department provider knowledge surrounding nonfatal strangulation injuries. Project Methods:Preintervention and postintervention surveys were administered to emergency department physicians and advanced practice providers assessing both provider comfort and knowledge regarding treatment of survivors of sexual assault, domestic violence, and strangulation. Key content areas included: physician comfort in treating sexual assault survivors, understanding of trauma-informed care, satisfaction with prior training regarding nonfatal strangulation, and physician attitudes. 6 vignette-style questions designed to evaluate knowledge in clinical scenarios were also administered. A 15-minute, interactive, educational presentation was administered during the pre-existing departmental meeting. Survey responses were collected via email and data was stored in REDCAP. Preintervention and postintervention results were compared via t-tests. Results:There were 22 pre-intervention and 10 post-intervention responses. Median years of practice were 8. Survey participants tended to rate awareness of imaging recommendations and resources, decisionmaking, history taking, and use of trauma-informed care higher than preintervention participants. Postintervention participants tended to answer more clinical vignettes correctly than preintervention participants. Conclusion and Potential Impact:A 15-minute educational intervention was effective in improving provider knowledge, confidence, and comfort in treating patients who have experienced non-fatal strangulation. In the future, similar interventions may be implemented in other emergency departments to increase awareness about the evaluation and treatment of nonfatal strangulation injuries.
背景和目的:在急诊科,医疗服务提供者需要对因性侵犯或人际暴力而遭受勒颈的患者进行评估。非致命性扼颈可导致严重伤害,包括颈动脉夹层。鉴于勒伤的发生率很高,医疗服务提供者必须对自己为这类人群做出的决策充满信心。以前的教育干预措施有效地提高了医疗服务提供者对性侵犯和家庭暴力患者的认识,但是,还没有任何研究是以提高医疗服务提供者对这一人群中勒伤的认识为目标的。我们的目标是评估并提高急诊科医疗服务提供者对非致命性勒伤的认识。项目方法:我们对急诊科医生和高级医疗服务提供者进行了干预前和干预后调查,以评估医疗服务提供者在治疗性侵犯、家庭暴力和勒杀幸存者方面的舒适度和知识。主要内容包括:医生在治疗性侵犯幸存者时的舒适度、对创伤知情护理的理解、对之前有关非致命性勒杀的培训的满意度以及医生的态度。此外,还设计了 6 个小插曲式问题,用于评估临床场景中的知识。在事先举行的科室会议期间,还进行了 15 分钟的互动式教育演示。调查回复通过电子邮件收集,数据存储在 REDCAP 中。通过 t 检验比较干预前和干预后的结果。结果:干预前有 22 份回复,干预后有 10 份回复。从业年限中位数为 8 年。调查参与者对成像建议和资源、决策制定、病史采集和使用创伤知情护理的认识程度往往高于干预前的参与者。与干预前的参与者相比,干预后的参与者往往能正确回答更多的临床小故事。结论和潜在影响:15 分钟的教育干预能有效提高医疗服务提供者的知识水平、自信心以及治疗非致命性勒杀患者的舒适度。今后,其他急诊科也可实施类似的干预措施,以提高对非致命性勒伤的评估和治疗的认识。
