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. \u0000Methods: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. \u0000Results: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. \u0000Conclusion: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.","PeriodicalId":20522,"journal":{"name":"Proceedings of IMPRS","volume":"5 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139438428","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}

{"title":"Clinical Features for Detecting Diabetic Macular Edema using Artificial Intelligence","authors":"Jeffrey Liu, Doaa Hassan Salem, Hunter Jill, S. Janga, Amir Hajrasouliha","doi":"10.18060/27721","DOIUrl":"https://doi.org/10.18060/27721","url":null,"abstract":"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. \u0000Methods: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. \u0000Results: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. \u0000Conclusion: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.","PeriodicalId":20522,"journal":{"name":"Proceedings of IMPRS","volume":"5 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139438480","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}

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. \u0000Methods: 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. \u0000Results: 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. \u0000Conclusion: 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.

Scofield, Jimmy Yen","doi":"10.18060/27762","DOIUrl":"https://doi.org/10.18060/27762","url":null,"abstract":"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. \u0000Experimental 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. \u0000Results: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. \u0000Conclusion 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.","PeriodicalId":20522,"journal":{"name":"Proceedings of IMPRS","volume":"48 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140510360","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}

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.  \u0000Methods: 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.  \u0000Results: 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.  \u0000Conclusion: 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.

Our objective was to evaluate outcomes of the PATH4YOU program to determine the distribution of contraceptive access among people in Indiana. \u0000Study 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. \u0000Results—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. \u0000Conclusion—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. \u0000Implications—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.

This project aims to identify socially vulnerable patients and evaluate the impact of SDOH on clinical outcomes.  \u0000Methods:  \u0000From 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.

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). \u0000Methods: \u0000Visium 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. \u0000Results: \u0000Between 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. \u0000Conclusion/ Clinical Impact and Implications: \u0000Neighborhood characterization provides insight into cell-cell interactions that drive kidney disease progression.

The research was conducted at University and Methodist Hospital radiology reading rooms. \u0000Results: 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. \u0000Conclusion: 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.","PeriodicalId":20522,"journal":{"name":"Proceedings of IMPRS","volume":" 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139625741","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}

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.","PeriodicalId":20522,"journal":{"name":"Proceedings of IMPRS","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139625866","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}
