Background/Objective:Interfacility transfers are an integral part of integrated systems of care in modern healthcare. Many transferred patients are older adults, a particularly vulnerable patient population. Unfortunately, interfacility transfers can result in discomfort during the transport, increased distance from family and home, a significant bill for the ambulance ride, and risk of an accident occurring during transport. Methods:To better understand the experiences of older adults before, during, and after interfacility transfer, cognitive interviews were performed with patients and their caregivers at the bedside of the receiving hospital. A standard set of questions was used to assess multiple aspects of the interfacility transfer process including the consent process at the sending hospital, experience with the transfer, and perceived benefits/harms resulting from the transfer. Results:21 patients and 14 caregivers were interviewed in this study and five themes were present throughout these conversations. These themes included, a perceived lack of participation in the decision to be transferred, failed expectations at the receiving hospital, and greater trust in trauma centers like Methodist Hospital. Conclusion:Our interviews demonstrate a greater need for thorough consent for transfer at sending hospitals discussing the realistic outcomes and risks that can be expected from interfacility transfer. With these conversations patients and their caregivers can be empowered to make informed decisions about their care and will likely be more satisfied with the care that they receive and know what to expect during their treatment.
背景/目的:机构间转运是现代医疗保健综合系统中不可或缺的一部分。许多被转运的病人都是老年人,这是一个特别脆弱的病人群体。不幸的是,机构间转运可能导致转运过程中的不适、与家人和家庭距离的增加、救护车费用的增加以及转运过程中发生意外的风险。方法:为了更好地了解老年人在医院间转运之前、期间和之后的经历,我们在接收医院的床边对患者及其护理人员进行了认知访谈。访谈中使用了一套标准问题来评估医院间转运过程的多个方面,包括转运医院的同意程序、转运经验以及转运带来的利益/伤害感知。结果:21 名患者和 14 名护理人员接受了本研究的访谈,在整个访谈过程中有五个主题。这些主题包括:转院决定中缺乏参与感、对接收医院的期望落空,以及对卫理公会医院等创伤中心的更大信任。结论:我们的访谈表明,更有必要在转院时征得转送医院的全面同意,讨论医院间转院的实际结果和预期风险。有了这些对话,患者及其护理人员就有能力对其护理做出明智的决定,并可能对所接受的护理更加满意,同时了解治疗期间的预期情况。

Background:Vision is a valuable part of life: influencing our perception of the world and of memories. Diabetes, and more specifically, Diabetic Retinopathy (DR) can affect our vision, taking away sight potentially permanently if left untreated. Currently, Diabetic Retinopathy is the leading cause for adult blindness and will continue to rise with increasing prevalence of adult diabetes. Diabetic Macular Edema (DME), a complication of DR, is diagnosed by ophthalmologists using optical coherence tomography (OCT); however, the sheer amount of DME-related imaging creates a time strain on ophthalmologists, creating a demand to further optimize the image reading process. In this study, we hypothesize that increasing the rate and ease of diagnosing DME by introducing artificial intelligence-based methods in primary medical clinics will increase the long-term preservation of ocular health in diabetic patients. Methods:Due to the nature of our retrospective cohort study, consent was not acquired and images were also de-identified. We categorized 676 patient files by HbA1c, non-proliferative diabetic retinopathy (NPDR) severity, and proliferative diabetic retinopathy (PDR). Retinal OCT images were annotated to identify central macular edema, a common feature of DME. Retinal fundus images were also annotated to identify microaneurysms and hemorrhages, two additional features commonly used for detecting either DR or DME. Results:A lesion features dataset was prepared to train our AI model. OCT and fundus imaging features were extracted and combined to train the AI model for DME detection. From annotations of the in-house Macular thickness dataset, it was seen that 167 patients had DME from the total 389 diabetic retinopathy patients. Conclusion:We will continue to prepare more datasets like the macular thickness dataset for our AI. We predict that after our AI receives substantial training with the datasets, the AI will potentially demonstrate some capability of diagnosing DME, supporting its use in medical diagnostics.
背景:视力是生命中宝贵的一部分:影响我们对世界和记忆的感知。糖尿病,尤其是糖尿病视网膜病变(DR)会影响我们的视力,如果不及时治疗,可能会永久性地夺走我们的视力。目前,糖尿病视网膜病变是导致成人失明的主要原因,而且随着成人糖尿病发病率的增加,其发病率还将继续上升。糖尿病性黄斑水肿(DME)是糖尿病性视网膜病变的并发症之一,眼科医生使用光学相干断层扫描(OCT)对其进行诊断;然而,与糖尿病性黄斑水肿相关的大量成像给眼科医生造成了时间压力,从而产生了进一步优化图像阅读过程的需求。在本研究中,我们假设通过在基层医疗诊所引入基于人工智能的方法来提高 DME 的诊断率和简易性,将提高糖尿病患者眼部健康的长期保护率。方法:由于我们的研究属于回顾性队列研究,因此未征得患者同意,同时也对图像进行了去标识化处理。我们按照 HbA1c、非增殖性糖尿病视网膜病变(NPDR)严重程度和增殖性糖尿病视网膜病变(PDR)对 676 份患者档案进行了分类。对视网膜 OCT 图像进行了注释,以识别黄斑中心水肿,这是 DME 的常见特征。此外,还对视网膜眼底图像进行了注释,以识别微动脉瘤和出血,这是检测 DR 或 DME 的另外两个常用特征。结果:我们准备了一个病变特征数据集来训练人工智能模型。我们提取了 OCT 和眼底成像特征,并将其结合起来训练用于 DME 检测的人工智能模型。从内部黄斑厚度数据集的注释中可以看出,在总共 389 名糖尿病视网膜病变患者中,有 167 名患者患有 DME。结论:我们将继续为人工智能准备更多像黄斑厚度数据集这样的数据集。我们预测,在我们的人工智能接受了大量的数据集训练后,人工智能将有可能显示出诊断 DME 的某些能力,从而支持其在医疗诊断中的应用。

Background/Hypothesis: Brief resolved unexplained events (BRUEs) are events in infants characterized by cyanosis, abnormal breathing, abnormal tone, and altered responsiveness. Practice guidelines define high-risk and low-risk BRUEs and do not recommend imaging in low-risk patients. We evaluated imaging in these patients and hypothesized that high-risk patients would have more imaging studies and abnormalities. Methods: Using the radiology information system, a retrospective review was performed between 2016-2022 for patients <1 year presenting with BRUE. Defined search terms were used to identify imaging within one week of presentation. Patients were evaluated for clinical presentation, medical history, physical examination, imaging studies ordered, and final diagnoses. Results: 126 patients were identified. 113 patients (46 female; 93 high-risk), between 3 and 355 days old (average age 97 days), met inclusion criteria. Imaging included chest radiographs (99), head CTs (24), brain MRIs (19), skeletal surveys (16), and others (22). There was no difference in the number of imaging studies obtained between these groups (p=0.423, Mann-Whitney U test). However, a greater proportion of high-risk patients had imaging abnormalities (p=0.023, Fisher’s exact test). Only 1/20 (5%) low-risk patients had abnormal imaging (PCR proven viral bronchiolitis). 26/93 (28%) high-risk patients had abnormal findings, most commonly on chestradiographs (15), brain MRIs (9), head CTs (4), and skeletal surveys (3). 18/26 high-risk patients had imaging abnormalities leading to a diagnosis other than BRUE (viral bronchiolitis, bronchopulmonary dysplasia, nonaccidental trauma, perinatal HSV infection, ventricular septal defect, double aortic arch, intestinal malrotation, and neurofibromatosis). Overall, 7/93 (7.5%) high-risk BRUE patients had significant pathology. Conclusion: High-risk patients were more likely to have an imaging abnormality compared to low-risk patients, which is consistent with current imaging recommendations given only one low-risk imaging abnormality. Interestingly, 7.5% of the high-risk patients had significant pathology diagnosed by imaging.
背景/假设:短暂缓解的不明原因事件(BRUEs)是指以发绀、呼吸异常、张力异常和反应性改变为特征的婴儿事件。实践指南定义了高风险和低风险 BRUE,不建议对低风险患者进行成像检查。我们对这些患者进行了影像学评估,并假设高风险患者将接受更多影像学检查并出现更多异常。方法:利用放射学信息系统,对2016-2022年间出现BRUE的1岁以下患者进行了回顾性审查。使用定义的搜索条件来识别发病一周内的影像学检查。对患者的临床表现、病史、体格检查、影像学检查和最终诊断进行评估。结果:确定了 126 名患者。符合纳入标准的患者有 113 名(46 名女性;93 名高风险患者),年龄在 3 到 355 天之间(平均年龄为 97 天)。影像学检查包括胸片(99 例)、头部 CT(24 例)、脑部 MRI(19 例)、骨骼检查(16 例)及其他(22 例)。这些组别之间获得的影像学检查数量没有差异(P=0.423,曼-惠特尼 U 检验)。不过,高危患者中出现影像学异常的比例更高(P=0.023,费雪精确检验)。只有 1/20(5%)名低风险患者出现影像学异常(PCR 证实为病毒性支气管炎)。26/93(28%)名高危患者出现异常,最常见的是胸部X光片(15)、脑磁共振成像(9)、头部 CT(4)和骨骼测量(3)。18/26 名高危患者的影像学异常导致了除 BRUE 以外的其他诊断(病毒性支气管炎、支气管肺发育不良、非意外创伤、围产期 HSV 感染、室间隔缺损、双主动脉弓、肠错位和神经纤维瘤病)。总体而言,7/93(7.5%)名高危 BRUE 患者存在重大病变。结论:与低风险患者相比,高风险患者更有可能出现影像学异常,这与目前的影像学建议是一致的,因为只有一种低风险影像学异常。有趣的是,7.5% 的高危患者通过影像学检查确诊为重大病变。

Background and Hypothesis:Every year, more than 690,000 people in the United States suffer an ischemic stroke. Many survivors are left with long-term disability. While the initial insult to the brain is caused by hypoxia resulting from cerebral artery occlusion, a secondary insult is caused by peripheral immune cell infiltration across the blood brain barrier (BBB) and subsequent cytotoxic insult. Previous studies have demonstrated that interferon beta (IFNβ) limits peripheral immune cell infiltration across the BBB and reduces brain infarction volume. We hypothesize that during ischemic stroke IFNβ suppresses brain endothelial cells (bECs) activation to reduce their expression of adhesion molecules as one of the mechanisms by which it decreases peripheral immune cell infiltration across the BBB. Experimental Design:In this project, bEnd.3 cells, a cell line of bECs, were activated by TNF-α, a pro-inflammatory cytokine. Tissue plasminogen activator (tPA), an FDA-approved thrombolytic for ischemic stroke, was included in the study. bEnd.3 cells were treated with IFNβ at 1.5 hours prior TNF-α or TNF-α + tPA stimulation to evaluate its modulation of adhesion cell expression. The adhesion molecule expression was determined by flow cytometry. Results were further confirmed by in vivo studies in which stroke animals were subjected to tPA treatment in the presence or absence of IFNβ. Results:Our results showed that TNF-α induced ICAM-1, VCAM-1, E-selectin, and P-selectin expression. Importantly, we found IFNβ suppressed the expression of aforementioned adhesion molecules in bEnd.3 cells treated with TNF-α or TNF-α+tPA. Our in vivo results demonstrated that IFNβ treatment reduced ICAM-1 and E-selectin, but not VCAM-1 or P-selectin expression in the ischemic brain. Conclusion and Potential Impact:Our study demonstrates that IFNβ modulates bEC expression of adhesion molecules in vitro and in vivo of ischemic stroke, suggesting IFNβ, an FDA-approved drug for Multiple Sclerosis, shows potential to improve ischemic stroke outcomes.
背景与假设:美国每年有 69 万多人罹患缺血性中风。许多幸存者会留下长期残疾。脑动脉闭塞导致的缺氧是对大脑的最初损伤,而外周免疫细胞跨越血脑屏障(BBB)的浸润和随后的细胞毒性损伤则是对大脑的二次损伤。先前的研究表明,干扰素β(IFNβ)可限制外周免疫细胞跨血脑屏障浸润,并减少脑梗塞体积。我们推测,在缺血性中风期间,IFNβ会抑制脑内皮细胞(bECs)的活化,从而减少其粘附分子的表达,这是IFNβ减少外周免疫细胞跨BBB浸润的机制之一。实验设计:在该项目中,bECs细胞系bEnd.3细胞被促炎细胞因子TNF-α激活。在 TNF-α 或 TNF-α + tPA 刺激前 1.5 小时,用 IFNβ 处理 bEnd.3 细胞,以评估其对粘附细胞表达的调节作用。粘附分子的表达是通过流式细胞术测定的。在IFNβ存在或不存在的情况下,对中风动物进行tPA处理的体内研究进一步证实了这些结果。结果:我们的研究结果表明,TNF-α能诱导ICAM-1、VCAM-1、E-选择素和P-选择素的表达。重要的是,我们发现 IFNβ 可抑制 TNF-α 或 TNF-α+tPA 处理的 bEnd.3 细胞中上述粘附分子的表达。我们的体内研究结果表明,IFNβ处理可减少缺血脑中ICAM-1和E-选择素的表达,但不能减少VCAM-1或P-选择素的表达。结论和潜在影响:我们的研究表明,IFNβ可调节缺血性脑卒中体外和体内bEC粘附分子的表达,这表明IFNβ--一种FDA批准的治疗多发性硬化症的药物--具有改善缺血性脑卒中预后的潜力。

Changes in Transport Mode for Pediatric Trauma Patients Before and After the COVID-19 Pandemic COVID-19 大流行前后儿科创伤患者转运方式的变化
Pub Date : 2024-01-11 DOI: 10.18060/27956

Background: The Emergency Medical Services (EMS) system has faced significant stress due to the COVID-19 pandemic and now workforce issues. This study was performed to evaluate potential changes in pediatric trauma patient transport over that time period. We hypothesized that more trauma patients would use private transportation/personal vehicles to arrive at the ED in the post-pandemic time frame when compared pre-pandemic.  Methods: This was a retrospective cohort study of patients that were admitted to the Emergency Department of Riley Hospital for Children between 01/01/2017 to 12/31/2022.  Patients were excluded if they were transferred from another hospital or had mechanisms of injury including burns, suffocations, drownings, hangings, medical, and ingestions.  Pre- and post-COVID patients were defined as admission to the ED before or after March 25, 2020, the day after a stay at home orders were implemented in Indiana.  Univariate and multivariate analyses were performed.  Results: A total of 4,116 patients matching the criteria were identified with 52% arriving after the start of the COVID-19 shut down orders.  30.6% of patients arrived by private operated vehicles (POV) during pre-covid times and 30.3% in the post-covid years (p=0;39). A logistic regression analysis was performed for mortality which demonstrated that transport mode (ground ambulance vs helicopter vs POV) was not statistically associated with mortality rate (OR 0.36, 95% CI 0.12 – 1.10, p=0.07), when controlling for important clinical variables associated with injury severity.  Conclusion: There was no statistical difference in arrival by POV before and after the COVID-19 pandemic in our cohort.  Additionally, there was no significant data to suggest that transport mode was associated with mortality. Further research should be done to assess potential barriers to transport to pediatric trauma centers, particularly considering ongoing EMS workforce strains. 
背景:由于 COVID-19 大流行和目前的劳动力问题,紧急医疗服务 (EMS) 系统面临着巨大的压力。本研究旨在评估儿科创伤患者转运在这段时间内可能发生的变化。我们假设,与大流行前相比,在大流行后的一段时间内,会有更多的外伤患者使用私人交通工具/私家车到达急诊室。 方法:这是一项回顾性队列研究,研究对象是 2017 年 1 月 1 日至 2022 年 12 月 31 日期间莱利儿童医院急诊科收治的患者。 如果患者是从其他医院转来的,或者受伤机制包括烧伤、窒息、溺水、绞死、内伤和误食,则将其排除在外。 COVID之前和之后的患者定义为在印第安纳州实施居家护理令的第二天,即2020年3月25日之前或之后入院的急诊患者。 进行了单变量和多变量分析。 结果:共确定了 4116 名符合标准的患者,其中 52% 的患者是在 COVID-19 关闭令生效后到达的。 30.6%的患者在停运前乘坐私人运营车辆(POV)抵达,30.3%的患者在停运后乘坐私人运营车辆(POV)抵达(P=0;39)。对死亡率进行了逻辑回归分析,结果表明,在控制了与受伤严重程度相关的重要临床变量后,运输方式(地面救护车 vs 直升机 vs POV)与死亡率无统计学关系(OR 0.36,95% CI 0.12 - 1.10,p=0.07)。 结论在我们的队列中,COVID-19 大流行前后通过 POV 到达的人数没有统计学差异。 此外,没有重要数据表明运输方式与死亡率有关。应开展进一步研究,以评估将患者送往儿科创伤中心的潜在障碍,特别是考虑到目前急救医疗队伍的紧张状况。

Further research should be done to assess potential barriers to transport to pediatric trauma centers, particularly considering ongoing EMS workforce strains. ","PeriodicalId":20522,"journal":{"name":"Proceedings of IMPRS","volume":"28 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139533441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective—PATH4YOU is Indiana’s first state-wide contraceptive access project and provides contraceptive access via in-person and telehealth visits using a reproductive justice framework. Our objective was to evaluate outcomes of the PATH4YOU program to determine the distribution of contraceptive access among people in Indiana. Study Design—We analyzed programmatic data of reproductive-age people who received care in the PATH4YOU program from September 2021 to June 2023. All participants received pregnancy intention screening, comprehensive contraceptive counseling and decision support, and no-cost contraceptive method access, including long-acting reversible contraception (LARC). We evaluated age, location (county), primary method of contraception received, partner site visited, and in-person vs telehealth visit type using descriptive statistics. Geographical mapping analysis was used to determine areas of Indiana most impacted by the PATH4YOU program. Results—Between September 2021 and June 2023, 1,024 people received care at 1,231 visits through the PATH4YOU program. The average age of participants was 27.6 years old. A significant (49.3%) proportion of the participants live in Marion County. The most common primary methods of contraception were the implant (25.8%), contraceptive pills (20.5%), and intrauterine devices (16.0%). The most visited partner sites included People’s Health Center in Indianapolis (24.8%) and via telehealth (22.5%). Most people received contraceptive access in one in-person (66.0%) or telehealth (17.9%) visit. Conclusion—The PATH4YOU state-wide contraceptive access project provided a range of contraceptive methods via both in-person and telehealth visits to a wide reach of people across multiple counties in Indiana. Implications—The unique PATH4YOU model of care using both in-person and telehealth visits is a novel way to increase contraceptive access throughout a state with highly variable access to traditional in-person contraceptive care. Further research is necessary to evaluate direct impacts of the program on minoritized and traditionally excluded populations to evaluate long-term outcomes like maternal mortality.
目标-PATH4YOU 是印第安纳州首个全州范围内的避孕药具获取项目,该项目采用生殖正义框架,通过面对面访问和远程医疗访问提供避孕药具获取服务。我们的目标是对 PATH4YOU 计划的成果进行评估,以确定避孕药具在印第安纳州人群中的分布情况。研究设计--我们分析了 2021 年 9 月至 2023 年 6 月期间接受 PATH4YOU 计划治疗的育龄人群的计划数据。所有参与者都接受了怀孕意向筛查、全面的避孕咨询和决策支持,并获得了免费的避孕方法,包括长效可逆避孕法(LARC)。我们使用描述性统计方法评估了年龄、地点(县)、接受的主要避孕方法、访问过的伴侣网站以及亲自访问与远程医疗访问类型。我们还利用地理地图分析来确定印第安纳州受 PATH4YOU 计划影响最大的地区。结果--在 2021 年 9 月至 2023 年 6 月期间,共有 1,024 人通过 PATH4YOU 计划接受了 1,231 次就诊。参与者的平均年龄为 27.6 岁。很大一部分参与者(49.3%)居住在马里恩县。最常见的主要避孕方法是皮下埋植(25.8%)、避孕药(20.5%)和宫内节育器(16.0%)。访问最多的合作站点包括印第安纳波利斯的人民健康中心(24.8%)和远程医疗(22.5%)。大多数人都是通过一次上门服务(66.0%)或远程医疗(17.9%)获得避孕药具的。结论--PATH4YOU 全州避孕药具获取项目通过上门服务和远程医疗服务为印第安纳州多个县的广大群众提供了一系列避孕方法。启示--PATH4YOU 采用亲临现场和远程医疗访问的独特护理模式是一种新颖的方法,可在一个获得传统亲临现场避孕护理的机会极不稳定的州提高避孕普及率。有必要开展进一步研究,以评估该计划对少数民族和传统上被排斥人群的直接影响,从而评估孕产妇死亡率等长期结果。

Background and Objective:  Advances in the treatment of cystic fibrosis (CF) with cystic fibrosis transmembrane regulator modulators have improved morbidity and mortality, however, clinical outcomes vary among genetically similar patients due to contributions of social determinants of health (SDOH). Pancreatic insufficiency, CF-related diabetes (CFRD), Pseudomonas infections, and lower BMI increase risk of severe lung disease, measured by forced expiratory volume in 1 second (FEV1). This project aims to identify socially vulnerable patients and evaluate the impact of SDOH on clinical outcomes.  Methods:  From January to July 2023, SDOH screeners were distributed to families of children with CF at Riley Hospital for Children, documenting transportation, housing, food insecurity, insurance, and medication costs. Clinical outcomes for each patient including FEV1% predicted, BMI/WFL percentile, CFRD, hospitalizations, respiratory infections with Pseudomonas aeruginosa, and pancreatic insufficiency within the past 12 months were recorded. Patients were categorized by SDOH vulnerability, and associations with poor clinical outcomes were analyzed using the Chi-squared test of independence.  Results:  A total of 193 screeners were analyzed: males represented 52.6% of the cohort, 2.60% identified as non-white race, and 3.65% reported Hispanic ethnicity. Overall, 51.8% screened positive for at least one SDOH (SDOH+) and 48.1% screened negative (SDOH-). The average FEV1% predicted decline among SDOH+ patients was 5.79% and 3.51% among SDOH- patients. SDOH+ patients were more likely to have at least a 5% decline in FEV1% predicted (p=0.037) and to be hospitalized due to exacerbations of CF lung disease at least once in the past 12 months (p=0.030). Although low BMI percentile, Pseudomonas infection, and CFRD were not significantly associated with SDOH, socially vulnerable patients demonstrated higher rates of these clinical outcomes.  Conclusion and Clinical Implications:  SDOH impact CF clinical outcomes. Screeners are effective in identifying socially vulnerable patients and serve as the first step in addressing unmet social needs. 
背景和目的: 使用囊性纤维化跨膜调节器调节剂治疗囊性纤维化(CF)的进展改善了发病率和死亡率,然而,由于健康的社会决定因素(SDOH)的影响,基因相似的患者的临床结果各不相同。胰腺功能不全、CF 相关糖尿病(CFRD)、假单胞菌感染和较低的体重指数(BMI)会增加严重肺部疾病的风险(以 1 秒用力呼气容积(FEV1)衡量)。本项目旨在确定社会弱势患者,并评估 SDOH 对临床结果的影响。 方法: 从 2023 年 1 月到 7 月,向莱利儿童医院的 CF 患儿家庭发放 SDOH 筛查表,记录交通、住房、食品不安全、保险和药物费用。记录了每位患者的临床结果,包括预测 FEV1%、BMI/WFL 百分位数、CFRD、住院治疗、铜绿假单胞菌呼吸道感染以及过去 12 个月内的胰腺功能不全。根据 SDOH 易感性对患者进行分类,并使用卡方检验分析其与不良临床结果的关系。 结果 共对 193 名筛查者进行了分析:其中男性占 52.6%,2.60% 为非白人,3.65% 为西班牙裔。总体而言,51.8%的筛查者对至少一项 SDOH(SDOH+)呈阳性,48.1%的筛查者对一项 SDOH(SDOH-)呈阴性。SDOH+患者的平均预测 FEV1% 下降率为 5.79%,SDOH-患者的平均预测 FEV1% 下降率为 3.51%。SDOH+ 患者的 FEV1% 预测值至少下降 5%(P=0.037),且在过去 12 个月中至少因 CF 肺病加重住院一次(P=0.030)的可能性更大。虽然低体重指数百分位数、假单胞菌感染和 CFRD 与 SDOH 无显著相关性,但社会弱势患者出现这些临床结果的比例更高。 结论和临床意义: SDOH 对 CF 临床结果有影响。筛查人员可有效识别社会弱势患者,并作为解决未满足的社会需求的第一步。

Background: Lupus nephritis (LN) affects 1 in 3 individuals with systemic lupus erythematosus. Suboptimal treatment precipitates irreversible kidney damage, leading to end stage renal disease. Kidney damage in lupus is characterized by immune cells injuring epithelial, endothelial, and stromal cells. We characterized molecular neighborhoods composed of immune cells interacting with resident cells of the kidney through spatial transcriptomics (ST). Methods: Visium ST experiments were conducted in 8 healthy controls (233 glomeruli) and 3 LN samples (48 glomeruli). Cell type labels from the Kidney Precision Medicine Project single cell RNA-seq atlas were transferred to deconvolute ST spots into specific cell types. Using histology and NPHS2 expression, glomeruli were selected as functional tissue units. Data were normalized, dimensionally reduced, and clustered with Seurat v4. Spatially anchored gene signatures of LN were identified. Glomeruli were re-clustered according to cell composition, to identify associated neighborhoods by fisher’s exact test. We characterized the cell composition, differentially expressed genes (DEGs), and pathways of relevant neighborhoods. Results: Between LN and control glomeruli, we identified HSPA8, PLEK, COL1A2 DEGs, associated with hypoxia, fibrosis, and immune response. We identified glomerular neighborhoods consistent with immune complex deposition, endothelial dysfunction (e.g. wire loop lesions), and mesangial cell expansion enriched in LN (p<0.05). Immune complex-mediated injury neighborhoods were characterized by interferon signaling, endothelial cell migration, and vascular genesis, consistent with DEGs BST2, CXCL12, and ENG. Endothelial dysfunction neighborhoods present cellular adhesion, immune cell signaling, and hypoxic pathways. DEGs included ITGB2, HLA-DPB1, and EGR1. Pathways enriched in mesangial expansion neighborhoods included matrix adhesion, podocyte development, and ERK1 and ERK2 cascade, aligned with ITGB3, NPHS1, and APOE DEGs. Conclusion/ Clinical Impact and Implications: Neighborhood characterization provides insight into cell-cell interactions that drive kidney disease progression. Future directions will change how kidney biopsy specimens drive treatment by delineating specific cell-cell interactions, linking molecular and histopathological signatures, and defining genes associated with therapeutic resistance.
背景:狼疮肾炎(LN)影响着三分之一的系统性红斑狼疮患者。治疗不当会引发不可逆的肾损伤,导致终末期肾病。狼疮肾损伤的特点是免疫细胞损伤上皮细胞、内皮细胞和基质细胞。我们通过空间转录组学(ST)描述了免疫细胞与肾脏常驻细胞相互作用的分子邻域。研究方法在 8 个健康对照组(233 个肾小球)和 3 个 LN 样本(48 个肾小球)中进行了 Visium ST 实验。将肾脏精准医学项目单细胞 RNA-seq 图谱中的细胞类型标签转移到特定细胞类型的 ST 点上。通过组织学和 NPHS2 表达,选择肾小球作为功能组织单位。数据经过归一化、降维处理,并使用 Seurat v4 进行聚类。确定了 LN 的空间锚定基因特征。根据细胞组成对肾小球进行重新聚类,通过 Fisher's exact 检验确定相关邻域。我们对相关邻域的细胞组成、差异表达基因(DEG)和通路进行了特征描述。结果在 LN 肾小球和对照肾小球之间,我们发现了与缺氧、纤维化和免疫反应相关的 HSPA8、PLEK 和 COL1A2 DEGs。我们在 LN 中发现了与免疫复合物沉积、内皮功能障碍(如线环病变)和间质细胞扩增一致的肾小球邻域(p<0.05)。免疫复合物介导的损伤邻域以干扰素信号、内皮细胞迁移和血管形成为特征,与 DEGs BST2、CXCL12 和 ENG 相一致。内皮功能障碍邻域呈现细胞粘附、免疫细胞信号传导和缺氧通路。DEGs包括ITGB2、HLA-DPB1和EGR1。间质扩张邻域中富集的通路包括基质粘附、荚膜细胞发育、ERK1和ERK2级联,与ITGB3、NPHS1和APOE DEGs一致。结论/临床影响和意义:邻居特征描述有助于深入了解驱动肾脏疾病进展的细胞-细胞相互作用。未来的研究方向将通过界定特定的细胞-细胞相互作用、连接分子和组织病理学特征以及定义与治疗耐药性相关的基因,改变肾活检标本推动治疗的方式。

Biopsy or no biopsy? Risk of Malignancy in Thyroid Nodules Based on TI-RADS Criteria 活检还是不活检?基于 TI-RADS 标准的甲状腺结节恶性风险
Pub Date : 2024-01-11 DOI: 10.18060/27782
Faadil Shariff, Vivek Halappa
Purpose: To assess the risk of malignancy in thyroid nodules recommended for biopsy using the American College of Radiology (ACR) Thyroid Imaging Reporting & Data System (TIRADS). Methods: We conducted a retrospective review of ultrasound (US) guided thyroid biopsies performed from 2018- 2023 at IU Health hospitals for nodules which were recommended for biopsy based on ACR TI-RADS criteria and compared with histopathology results. The research was conducted at University and Methodist Hospital radiology reading rooms. Results: Of the total 210 thyroid nodules recommended for biopsy, only 8.57% of nodules biopsied were malignant. Positive malignancy rate for TR-3 was 10.2%, TR-4 was 7.1%, and TR-5 was 12.5%. TR-3 nodules less than 2.9 cm were all benign on histopathology. TR-4 nodules less than 1.5 cm were all benign on histopathology. TR-5 nodules were all benign on histopathology. The most common malignancy was papillary thyroid carcinoma. Conclusion: ACR TI-RADS is currently the standard of care for guidelines and lexicon for radiologists for characterizing thyroid nodules. Our results demonstrate that all TR-3 nodules less than 2.9 cm were all benign and most of the TR-4 and TR-5 nodules biopsied were benign on histopathology. The lower biopsy rate for positive malignancy even for TR-4 and TR-5 nodules respectively raises the need for revision for existing TI-RADS criteria, as more nodules could be followed up with ultrasound rather than percutaneous biopsy, which will alleviate patient anxiety as well as decrease overall healthcare costs.
目的:使用美国放射学会(ACR)甲状腺成像报告和数据系统(TIRADS)评估建议进行活检的甲状腺结节的恶性风险。方法:我们对2018-2023年期间IU Health医院根据ACR TI-RADS标准推荐进行活检的结节进行了超声(US)引导下甲状腺活检的回顾性研究,并与组织病理学结果进行了比较。研究在大学医院和卫理公会医院放射科阅片室进行。研究结果在建议活检的 210 个甲状腺结节中,只有 8.57% 的结节为恶性。TR-3的阳性恶性率为10.2%,TR-4为7.1%,TR-5为12.5%。组织病理学结果显示,小于 2.9 厘米的 TR-3 结节均为良性。小于 1.5 厘米的 TR-4 结节经组织病理学检查均为良性。TR-5结节的组织病理学检查结果均为良性。最常见的恶性肿瘤是甲状腺乳头状癌。结论ACR TI-RADS 是目前放射科医生描述甲状腺结节特征的标准指南和词典。我们的研究结果表明,所有小于 2.9 厘米的 TR-3 结节都是良性的,大多数活检的 TR-4 和 TR-5 结节在组织病理学上都是良性的。即使是TR-4和TR-5结节的活检阳性恶性率也较低,这就提出了修订现有TI-RADS标准的必要性,因为更多的结节可以通过超声而不是经皮活检进行随访,这将减轻患者的焦虑并降低总体医疗成本。

MicroRNA-150 (miR-150) as a Potential Biomarker for Diabetic Retinopathy 作为糖尿病视网膜病变潜在生物标记物的微RNA-150 (miR-150)
Pub Date : 2024-01-11 DOI: 10.18060/27785

Diabetic retinopathy (DR) is a known chronic complication of diabetes mellitus and is one of the leading causes of visual impairment. The chronic inflammation associated with DR poses large risks not only for the vasculature but also for the surrounding neuronal tissue. Potential biomarkers, especially those surrounding microRNAs (miRNAs), have been proposed to indicate the progression of DR. Levels of certain miRNAs have been shown to be either down or upregulated in type 1 diabetes patients and have shown correlations with specific types of DR. MicroRNA-150 (miR-150) has also been shown to have protective effects on cells in hypoxic environments, but when downregulated, miR-150 actually induces apoptosis. And, it has been shown to be downregulated in patients with type 1 and type 2 diabetes as well as patients with obesity. We hypothesize then that the levels of miR-150 from a peripheral blood sample should be indicative of the progression of DR and may be used for potential early intervention. In this project, we assessed miR-150 levels in the peripheral blood mononuclear cells (MNCs) of individuals with different severities of DR by isolating mononuclear cells and extracting RNA. We then reverse-transcribed the RNA into cDNA and used RT-qPCR to measure the levels of miR-150 in individuals with varying DR severity. MiR-150 levels in the MNCS were decreased in individuals with diabetes with no retinopathy, moderate NPDR and severe NPDR groups when compared to control individuals; however, there was a marginal increase in the miR-150 mild NPDR group. The data could show evidence that a peripheral blood draw could be used as a less invasive approach to assessing the severity of diabetic retinopathy in patients. This would change the disease management and future treatments individually.
众所周知,糖尿病视网膜病变(DR)是糖尿病的一种慢性并发症,也是导致视力损伤的主要原因之一。与糖尿病视网膜病变相关的慢性炎症不仅对血管,而且对周围的神经元组织都构成巨大风险。有人提出了一些潜在的生物标志物,尤其是与微小核糖核酸(miRNA)有关的生物标志物,以指示 DR 的进展。某些 miRNA 的水平在 1 型糖尿病患者中出现了下调或上调,并显示出与特定类型 DR 的相关性。微RNA-150(miR-150)也被证明对缺氧环境中的细胞有保护作用,但当其被下调时,miR-150实际上会诱导细胞凋亡。而且,在 1 型和 2 型糖尿病患者以及肥胖症患者中,miR-150 已被证明是下调的。因此我们推测,外周血样本中的 miR-150 水平应能指示 DR 的进展,并可用于潜在的早期干预。在该项目中,我们通过分离单核细胞并提取 RNA,评估了不同严重程度的 DR 患者外周血单核细胞(MNCs)中的 miR-150 水平。然后,我们将 RNA 反转录为 cDNA,并使用 RT-qPCR 测定不同严重程度 DR 患者的 miR-150 水平。与对照组相比,无视网膜病变的糖尿病患者、中度NPDR组和重度NPDR组的MNCS中的miR-150水平有所下降;然而,miR-150轻度NPDR组的水平略有上升。这些数据可以证明,外周血抽取可以作为一种创伤较小的方法来评估患者糖尿病视网膜病变的严重程度。这将单独改变疾病管理和未来的治疗方法。
{"title":"MicroRNA-150 (miR-150) as a Potential Biomarker for Diabetic Retinopathy","authors":"Conner Smith, Qianyi Luo, Neha Mahajan, Ashay Bhtwadekar","doi":"10.18060/27785","DOIUrl":"https://doi.org/10.18060/27785","url":null,"abstract":"Diabetic retinopathy (DR) is a known chronic complication of diabetes mellitus and is one of the leading causes of visual impairment. The chronic inflammation associated with DR poses large risks not only for the vasculature but also for the surrounding neuronal tissue. Potential biomarkers, especially those surrounding microRNAs (miRNAs), have been proposed to indicate the progression of DR. Levels of certain miRNAs have been shown to be either down or upregulated in type 1 diabetes patients and have shown correlations with specific types of DR. MicroRNA-150 (miR-150) has also been shown to have protective effects on cells in hypoxic environments, but when downregulated, miR-150 actually induces apoptosis. And, it has been shown to be downregulated in patients with type 1 and type 2 diabetes as well as patients with obesity. We hypothesize then that the levels of miR-150 from a peripheral blood sample should be indicative of the progression of DR and may be used for potential early intervention. In this project, we assessed miR-150 levels in the peripheral blood mononuclear cells (MNCs) of individuals with different severities of DR by isolating mononuclear cells and extracting RNA.
