To evaluate the complication and patency rate of superficial femoral vein transposition in tertiary care center.

When all access options in the upper extremity have been exhausted, an autologous access can be created in lower extremity. The purpose of this study is to report our experience with superficial femoral vein transposition (SFVT) results in terms of postoperative complication and patency rate. In the time period from January 1, 2019 to April 30, 2021, thirty-five cases of SFVT performed at our large tertiary care center Sindh Institute of Urology and Transplantation (SIUT). All patients had exhausted upper arm veins or had central vein obstructions. Medical records of all patients were traced, patients were interviewed using a standard proforma and evaluated the current AVF function in the OPD clinic or by telephone calls. Data including demographics and postoperative complications were collected. Thirty-nine cases of SFVT performed at our institute. Three were immediately lost to follow up so they were excluded from the study. Mean patient age was 30 ± 13.4 years. Most of our patients were females (57%) and 15 males (43%) with an average age of 29.05 years. The most common underlying renal diseasewas unknown in 16 (45%).Thirty-five patients included in the analysis; out of which primary failure observed in 4 patients, three patients were expired before fistula maturation and 3 were expired before 6 months. The remaining 25 fistulas patency rates were estimated. No any patient died due to fistulas related complication; patients died due to their primary disease. Our study shows that with appropriate patient selection, SFVT have low infection rates and patency that is comparable with other access types.

GCT-25. THE IMPACT OF RESIDUAL DISEASE ON THE OUTCOMES OF CENTRAL NERVOUS SYSTEM GERMINOMAS – A MULTICENTER INSTITUTION EXPERIENCE

Abstract BACKGROUND Germinomas make up about two-thirds of central nervous system (CNS) germ cell tumors and are highly radio-sensitive with excellent survival rate of more than 90%. Current standard of care involves the combination of chemotherapy with reduced-dose radiotherapy. Typically, patients with residual disease receive a higher dose of radiotherapy. However, recent clinical trials showed that there were no differences in the outcomes between those who had complete response (CR) versus partial response (PR) to initial chemotherapy. Hence, we aimed to assess the outcomes of germinoma patients based on the responses to both chemotherapy and radiotherapy. METHODS A multicenter retrospective chart review of patients with germinoma from four large academic institutions was conducted. RESULTS Data from 41 germinoma patients treated between 2011 and 2022 were analyzed. Thirty-two patients had stable disease (SD)(2), PR(28), or CR(2) to chemotherapy. At the end of radiotherapy, 12 had CR, 5 had PR, and 13 had SD. All patients were alive at the time of review, with a median duration of survival from diagnosis of 78.85 months (range 3.90-278.67). One patient experienced radiographic progression following chemotherapy with SD noted following radiotherapy. CONCLUSION Relapses are extremely rare in patients who have residual disease at the end of therapy for germinoma. Future prospective clinical trials are needed to test the possibility of treating germinoma patients who have residual disease with a dose of radiotherapy comparable to that used in patients who achieve complete response.

The relationship between neural processing efficiency during inter-hemispheric transfer, alcohol consumption, and sleep quality in college students: an ERP study

Objective: To examine relationships between sleep, alcohol consumption, and a physiological and behavioral marker of cognitive function in college students. College students are in a high risk category for high alcohol consumption and poor sleep quality, two unhealthful behaviors which can lead to poor mental health outcomes and compromised academic performance. Participants: Thirty college students from a large midwestern institution. Methods: Participants performed an interhemispheric transfer task while their electroencephalography was recorded for later examination of event-related potentials. They were also administered the Pittsburgh Sleep Quality Index, the Alcohol Use Disorders Identification Test, and the Alcohol Timeline Follow-Back. Results: Results demonstrate that increased alcohol consumption is associated with poor right-to-left interhemispheric transfer performance, and increased frontal P1 ERP amplitudes to neuro-ipsilateral targets requiring an interhemispheric-transfer. Conclusions: These findings assist in furthering explorations into the impacts of unhealthy behaviors in college students and underlying markers of simple cognitive and behavioral function.

The somatic mutation profile of estrogen receptor-positive HER2-negative metastatic breast cancer in Brazilian patients.

Breast cancer is the leading cause of cancer death among women worldwide. Studies about the genomic landscape of metastatic breast cancer (MBC) have predominantly originated from developed nations. There are still limited data on the molecular epidemiology of MBC in low- and middle-income countries. This study aims to evaluate the prevalence of mutations in the PI3K-AKT pathway and other actionable drivers in estrogen receptor (ER)+/HER2- MBC among Brazilian patients treated at a large institution representative of the nation's demographic diversity. We conducted a retrospective observational study using laboratory data (OC Precision Medicine). Our study included tumor samples from patients with ER+/HER2- MBC who underwent routine tumor testing from 2020 to 2023 and originated from several Brazilian centers within the Oncoclinicas network. Two distinct next-generation sequencing (NGS) assays were used: GS Focus (23 genes, covering PIK3CA, AKT1, ESR1, ERBB2, BRCA1, BRCA2, PALB2, TP53, but not PTEN) or GS 180 (180 genes, including PTEN, tumor mutation burden [TMB] and microsatellite instability [MSI]). Evaluation of tumor samples from 328 patients was undertaken, mostly (75.6%) with GS Focus. Of these, 69% were primary tumors, while 31% were metastatic lesions. The prevalence of mutations in the PI3K-AKT pathway was 39.3% (95% confidence interval, 33% to 43%), distributed as 37.5% in PIK3CA and 1.8% in AKT1. Stratification by age revealed a higher incidence of mutations in this pathway among patients over 50 (44.5% vs 29.1%, p=0.01). Among the PIK3CA mutations, 78% were canonical (included in the alpelisib companion diagnostic non-NGS test), while the remaining 22% were characterized as non-canonical mutations (identifiable only by NGS test). ESR1 mutations were detected in 6.1%, exhibiting a higher frequency in metastatic samples (15.1% vs 1.3%, p=0.003). Additionally, mutations in BRCA1, BRCA2, or PALB2 were identified in 3.9% of cases, while mutations in ERBB2 were found in 2.1%. No PTEN mutations were detected, nor were TMB high or MSI cases. We describe the genomic landscape of Brazilian patients with ER+/HER2- MBC, in which the somatic mutation profile is comparable to what is described in the literature globally. These data are important for developing precision medicine strategies in this scenario, as well as for health systems management and research initiatives.

Computationally derived transition points across phases of clinical care

The objective of this study is to use statistical techniques for the identification of transition points along the life course, aiming to identify fundamental changes in patient multimorbidity burden across phases of clinical care. This retrospective cohort analysis utilized 5.2 million patient encounters from 2013 to 2022, collected from a large academic institution and its affiliated hospitals. Structured information was systematically gathered for each encounter and three methodologies - clustering analysis, False Nearest Neighbor, and transitivity analysis - were employed to pinpoint transitions in patients’ clinical phase. Clustering analysis identified transition points at age 2, 17, 41, and 66, FNN at 4.27, 5.83, 5.85, 14.12, 20.62, 24.30, 25.10, 29.08, 33.12, 35.7, 38.69, 55.66, 70.03, and transitivity analysis at 7.27, 23.58, 29.04, 35.00, 61.29, 67.03, 77.11. Clustering analysis identified transition points that align with the current clinical gestalt of pediatric, adult, and geriatric phases of care. Notably, over half of the transition points identified by FNN and transitivity analysis were between ages 20 and 40, a population that is traditionally considered to be clinically homogeneous. Few transition points were identified between ages 3 and 17. Despite large social and developmental transition at those ages, the burden of multimorbidities may be consistent across the age range. Transition points derived through unsupervised machine learning approaches identify changes in the clinical phase that align with true differences in underlying multimorbidity burden. These transitions may be different from conventional pediatric and geriatric phases, which are often influenced by policy rather than clinical changes.

Association of Timing With Postoperative Complications in the Management of Open Distal Radius Fractures

Background: This study investigates whether open distal radius fractures (ODRFs) treated after 24 hours from time of injury have an increased risk of infection or overall complication profile compared with those treated within 24 hours. Methods: Retrospective review was performed of all patients treated for ODRF over a 6-year period at a single large academic institution. Postoperative complications included surgical site infections, need for revision irrigation and debridement, delayed soft tissue healing, loss of reduction, nonunion, and malunion. Results: One-hundred twenty patients were treated for ODRF. Mean (SD) age at time of injury was 59.92 (17.68) years. Twenty patients (16.7%) had postoperative complications. Regarding mechanism of injury, 78 (65.0%) had a low-energy and 42 (35.0%) had a high-energy injury. Age and fracture grade were not significant factors. Mean (SD) open wound size was 1.18 (1.57) cm. Mean (SD) time from injury presentation to the emergency department (ED) and first dose of intravenous antibiotics was 3.07 (4.05) hours and mean (SD) time from presentation to the ED and operative treatment was 11.90 (6.59) hours, which did not show a significant association with postoperative complications. Twenty-four patients (20.0%) were treated greater than 24 hours after presentation to the ED, which was not significantly distinct from those treated within 24 hours. Conclusion: Patients with ODRFs treated after 24 hours were not associated with a greater risk of postoperative complications. Factors including age, energy and mechanism of injury, and fracture grade did not alter outcome in any statistically significant manner. Level of Evidence: Level IV

Attitudes, concerns, and perceptions of patients undergoing fertility treatments in an abortion restrictive state in the aftermath of the Roe v. Wade reversal.

To investigate the abortion views and reproductive concerns of current in vitro fertilization patients after the US Supreme Court Dobbs v. Jackson decision, which overturned the Roe v. Wade decision guaranteeing abortion access. This is a cross-sectional survey of English-speaking patients undergoing in vitro fertilization from January to November 2022 at a large academic institution in a state with restricted abortion care. Participants completed a 43-question electronic survey which measured feelings about abortion, future fertility treatments, and embryo disposition both quantitatively and qualitatively. Of 543 eligible patients, 267 (49%) consented to participate when called and were sent the survey. Of those, 180 (67%) completed it, resulting in a total completion rate of 33%. The majority believe abortion should be legal in the case of birth defects (90.8%) or rape or incest (90.3%). A significant proportion (91.4%) expressed concerns about abortion being illegal in the state that they receive infertility care. They reported some concern about making embryos (89.6%), controlling what happens to them (95.4%), and discarding them (94.4%). Patients wrote about their concerns with pursuing fertility treatments, fear of not having access to needed medical care, and the desire to remain close to states with less restrictive abortion laws. The evolving political landscape surrounding access to reproductive care has created significant concerns regarding legal regulation of these treatments and the disposition of embryos. By understanding patients' concerns, health care providers can more effectively advocate for the protection of fertility treatments and patients' autonomy in embryo disposition.

Where to Start: Creating a Roadmap for Collection Storage Planning Through a Collaborative Values-Based Approach: A National Endowment for the Humanities Sustaining Cultural Heritage Collections project at The New York Public Library

Collection storage is one of the most complex collaborations a museum, library, or archive can undertake. A high-level initial assessment can help overcome the inertia and complexity that overwhelms larger organizations due to the number of stakeholders, spaces, and collections. Large institutions need to rise above room-level preservation issues and focus on global, values-based thinking. With support from the Sustaining Cultural Heritage Collections (SCHC) program of the National Endowment for the Humanities (NEH), The Research Libraries of the New York Public Library (NYPL) designed a collaborative pre-planning exercise to inform long-range collection storage planning for over fifty storage areas within its Manhattan research centers. Pulling together experts in architecture, preservation environment, and sustainability to review NYPL’s storage needs in collaboration with an internal team of stakeholders, the project established foundations for ongoing values-based collaborative planning. Project design and considerations on synthesizing observations into recommendations are discussed in this article.

Factors Associated With Economics Course Performance at a Large Associate Degree-Granting Institution

Economics courses are often offered at community colleges and other institutions that primarily confer associate degrees. Despite this, little research has been conducted on performance in economics courses focusing on students attending these institutions. I use multinomial logistic models to determine which factors are related to performance in both introductory macroeconomics and introductory microeconomics at a large institution that primarily confers associate degrees and finds several factors associated with performance in these courses. Among the findings are that citizenship status, foreign-born status, and gender are associated with academic performance in economics courses as noncitizens, foreign-born, and male students outperform their citizen, U.S.-born, and female counterparts in certain circumstances. Additional results show that in-person classes are associated with higher pass rates and lower withdrawal rates.

Racial Disparities in Glioblastoma Genomic Alterations: A Comprehensive Analysis of a Multi-Institution Cohort of 2390 Patients

Although molecular biomarkers have significantly advanced precision oncology in glioblastoma, the prevalence of these biomarkers by race remains underexplored. This study aims to characterize the genomic alterations in glioblastoma across Asian, Black, and White patients, offering insights into racial disparities that may influence treatment outcomes and disease progression. Analyzing data from the American Association for Cancer Research Project Genomics Evidence Neoplasia Information Exchange database V13.0, this study examined 2390 primary glioblastoma samples from unique patients. Genomic alterations in 566 cancer-related genes were assessed using targeted next-generation sequencing panels from 3 large cancer institutes. The patient cohort included 112 Asians, 67 Blacks, and 2211 Whites. Statistical significance of associations between genomic alterations and race was evaluated using the chi-squared test, with the Benjamini-Hochberg method applied to control for multiple testing adjustments. Significant racial differences were observed in the frequency of genomic alterations. Asians exhibited a higher frequency of TP53 alterations (52.68%, P < 0.001), Blacks showed more frequent alterations in NRAS (7.46%, P < 0.001), MTOR (10.45%, P= 0.039), and TET2 (8.96%, P=0.039), and Whites had a higher occurrence of PTEN alterations (48.67%, P= 0.045). Additionally, Black patientshad an elevated rate of RET deletions (14.29%, P<0.001). This study identifies significant racial disparities in the alteration frequencies of 6 key glioblastoma genes: NRAS, TP53, MTOR, TET2, PTEN, and RET. These findings underscore the need for racial considerations in glioblastoma treatment strategies and highlight potential avenues for targeted therapeutic interventions. Further research is needed to explore the clinical implications of these genomic disparities.

Health information and technology engagement for clinical research and healthcare purposes (HITECH) survey of patients with a history of cancer.

e13672 Background: Digital technology offers oncology clinicians and researchers the ability to more closely monitor patients on therapy, including with electronic patient-reported outcomes (ePROs) and real-time passively collected data (for example: heart rate, oxygen saturation, etc.), via smartphone and wearable devices. In order to realize the potential for these technologies to improve patient experience and outcomes, it is critical that we consider the perspectives of patients to design usable and useful digital monitoring programs. Methods: We conducted a cross-sectional survey of cancer patients from a large academic medical institution to study willingness to use digital devices to collect data and to share discrete types of data for the purposes of medical care or research. A survey including baseline characteristics and questions pertaining to digital technology use was sent to participants enrolled in the UCLA Mental Health and Health Technology Research Registry, from November 2023 to January 2024. Participants were included if they were patients at UCLA, age 18 years and older, owned a smartphone and/or wearable device, and self-reported a history of cancer. The primary outcomes of interest were willingness to collect and share digital device data. We report summary statistics for our population. Results: A total of 690 patients participated in our survey. The majority were female (58.5%), 76.7% non-Hispanic white, 8.8% Hispanic, 5.8% Asian, and 2.0% black. Median age was 69 years old. Nearly all participants reported experience using a patient portal (98.9%). Willingness to collect data using a digital device, for the purposes of clinical care was reported by 93.3% of patients. Similarly, 92.0% were willing to use a device to collect health data for research purposes. Sharing patterns were similar regardless of whether data was intended to be for clinical care or research purposes (Table). Conclusions: The overwhelming majority of patients who own a smartphone and/or wearable are willing to collect health data on their digital device for either clinical care or research. There is a preference for sharing more objective clinical information (vitals and physical activity measurements), and less inclination to share subjective information (daily activity, symptoms, and mood). This could be attributable to the greater effort required to input information as well as skepticism of the usefulness of the subjective data. Notably, we must recognize that some patients are not well-represented in this study population. Their perspectives should also be explored to prevent widening of the digital divide.

Survival outcomes after autologous stem cell transplantation in T follicular helper type lymphoma.

7073 Background: T follicular helper (TfH)-type lymphoma is the most common subtype of peripheral T-cell lymphoma (PTCL). TfH lymphoma consists of angioimmunoblastic T-cell lymphoma (AITL), PTCL-TfH and Follicular T cell lymphoma. Most patients receive first-line treatment with anthracycline-based chemotherapy regimens with a potential role for consolidation with autologous stem cell transplantation (ASCT). In this study we analyzed survival outcomes in TfH lymphoma. Methods: This is an IRB approved retrospective analysis of patients with TfH lymphoma followed between 1997–2023 at the MD Anderson Cancer Center. Demographics, treatment history, response and survival outcomes were collected and analyzed. Next-generation sequencing (NGS) data was collected from a panel of 162 cancer-related genes. Survival analysis was performed with Kaplan Meier curves and comparisons were made with log-rank tests. Results: Of the 218 patients with TfH lymphoma for whom information was known about prior history of ASCT, 84 (39%) underwent ASCT (Table). At the time of diagnosis, the majority of patients had advanced stage disease (92% with stage III or IV) and elevated LDH (89%). NGS testing was available from 31 patients and the genes with recurrent somatic mutations identified were TET2 (65% patients), DNMT3A (29%), RHOA (13%), IDH2 (10%), PLCG1 (10%), TP53 (10%), ATM (6%), CCR7 (6%), JAK3 (6%) and STAT3 (6%). The three most common first-line treatments were CHOP (37%) followed by CHOEP (14%) and combination of brentuximab with either CHP or CHEP (13%). Patients who received ASCT were significantly younger (Table). The median overall survival (OS) for the cohort was 40.3 months with median progression-free survival (PFS) after first treatment of 12.5 months. Patients who received ASCT had a significantly higher overall survival (log-rank test p-value &lt; 0.01) compared to those who did not receive ASCT. Conclusions: This retrospective analysis of a large single institution cohort of patients with TfH lymphoma found significantly improved OS in those who underwent ASCT compared to those who did not. Given the sizeable proportion of patients who are transplant-ineligible due to age or comorbidities, there is a need for newer consolidation approaches for TfH lymphoma. [Table: see text]

Resident-as-Teacher: Can It Be Done With an E-Learning Module?

Background Resident-as-teacher initiatives are traditionally specialty-specific and performed in-person, limiting ability to disseminate essential teaching skills to all residents. Objective The aim of this study was to develop, implement, and evaluate a resident-as-teacher interactive e-learning module on growth mindset and coaching. Methods The module was designed and implemented between August 2022 and March 2023. It was distributed to postgraduate year (PGY) 1 residents in all specialties at a large academic institution. Completion rates, Likert ratings, and answers to 2 open-ended questions were used for assessment. Descriptive statistics and 1-way analysis of variance with Sîdák correction for multiple comparisons were performed on Likert ratings. Responses to open-ended questions were evaluated using content analysis. Results The module was completed by all 277 PGY-1 residents (100%), with the evaluation completed by 276 of 277 (99.6%) residents. Mean rating of the module's relevance to the role of resident teacher was 4.06±0.90 (5-point Likert scale), with general surgery residents rating the module less favorably compared to all specialties (3.28±1.06; P<.01; 95% CI 0.26-1.30). Open-ended comments revealed that residents most liked the delivery of relevant teaching strategies and the interactive design of the module. The most common area for suggested improvement was the addition of content such as teaching in challenging situations. Time needed for design, implementation, and evaluation was 80 hours total. Conclusions An e-learning module offers an interactive platform for teaching skills and was found to be an acceptable method of instruction for residents.

Fostering diversity and inclusion in the preempt CRC study through strategic site selection and innovative recruitment tools.

e23025 Background: Diversity in clinical studies is crucial in aligning the study population with the intended patient demographic. Freenome is developing a blood based test (MyTectCRC) intended to offer a convenient and accessible option for colorectal cancer (CRC) screening. Its clinical validation is supported by the PREEMPT CRC study, a prospective, multi-center observational study. PREEMPT CRC was able to achieve a diverse population representing various ethnic, racial, and geographical backgrounds that reflect the United States population. This analysis evaluates the significance of strategic site selection and use of forward-thinking study tools in achieving a diverse and inclusive study population. Methods: Starting in 2020, PREEMPT CRC enrolled participants aged 45-85 at average CRC risk. Eligible and consenting participants underwent a blood draw and a screening colonoscopy, with the blood sample analyzed by MyTectCRC. To ensure diversity, strategic site selection was employed beyond large academic institutions and hospitals to smaller sites and community hospitals. The study also incorporated a decentralized clinical trial (DCT) model to reach broader geographical areas and used electronic consenting and mobile phlebotomy (MP) services to facilitate enrollment. Results: PREEMPT CRC enrolled 48,995 participants and achieved ethnic/racial diversity comparable to 2020 U.S. Census for Blacks (11.2%, vs 13.6%), Asians (6.8%, vs 6.3%) and Hispanic or Hispanic/Latinx (11.2%, vs 19.1%), Native Hawaiian or Other Pacific Islander (0.3% vs 0.4%). The primary site types were community hospitals and regional clinics, accounting for 45.5% of all sites, followed by health systems (12.0%), research institutes (18.5%), and academic centers/teaching hospitals (16.0%). The community clinics and academic centers enrolled the highest proportion of Black participants within their sites (21.4% and 12.1%, respectively). Research institutions had the highest proportion of Asian (24.8%) and Hispanic/Latinx (18.3%) populations. There was no significant difference observed in male versus female distribution between site types. Within traditional sites, 32% used MP service. DCT enrolled 12,137 participants (24.7% of total) from every state in the U.S., including high representation from rural areas (24.5%). Conclusions: PREEMPT CRC integrated multiple methodologies and tools to enhance diversity and inclusivity. This multimodal approach ensured diversified representation through the participation of sites with harder-to-reach populations, which was reflected in ethnic and racial data, as well as the geographical diversity. PREEMPT CRC study underscores the importance of incorporating early diversity planning into study strategy and using multiple methods to broaden the representation of the patient population.

Spirometry Interpretation After Implementation of Race-Neutral Reference Equations in Children

The implications of adopting race-neutral reference equations on spirometry interpretation in children remain unknown. To examine how spirometry results and patterns change when transitioning from Global Lung Function Initiative (GLI) race-specific reference equations (GLIR, 2012) to GLI race-neutral reference equations (GLIN, 2023). Cross-sectional study of spirometry tests conducted in children aged 6 to 21 years between 2012 and 2022 at 2 large academic pediatric institutions in the US. Data were analyzed from September 2023 to March 2024. Data on participant characteristics and raw test measurements were collected. Forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and FEV1/FVC z scores and percent predicted were calculated using both GLIR and GLIN. In addition, test results were categorized into normal, obstructive, suspected restrictive, mixed, suspected dysanapsis, and uncategorized patterns based on z scores calculated using GLIR or GLIN. For each spirometry result, the difference between z scores and percent predicted when transitioning from GLIR to GLIN was calculated. The proportion of tests with a normal pattern and individual spirometry patterns changed by GLI reference equation applied were also examined. Data from 24 630 children were analyzed (mean [SD] age, 12.1 [3.8] years). There were 3848 Black children (15.6%), 19 503 White children (79.2%), and 1279 children of other races (5.2%). Following implementation of GLIN, FEV1 and FVC z scores decreased in Black children (mean difference, -0.814; 95% CI, -0.823 to -0.806; P < .001; and -0.911; 95% CI, -0.921 to -0.902; P < .001, respectively), while FEV1 and FVC z scores slightly increased (0.073; 95% CI, 0.069 to 0.076; P < .001). Similar changes were found when using percent predicted. In Black children, the number of tests with a normal pattern decreased from 2642 (68.7%) to 2383 (61.9%) (χ21 = 204.81; P < .001), mostly due to tests with a normal pattern transitioning to a suspected restrictive or uncategorized pattern. Opposite, albeit smaller, changes in spirometry results and patterns were seen in White children. In adjusted models, Black children had approximately 3-fold higher odds than White children of changing spirometry pattern following the implementation of GLIN (adjusted odds ratio, 3.15; 95% CI, 2.86 to 3.48; P < .001). Pronounced differences in spirometry results and patterns were found when switching between GLI reference equations, which markedly differed by race. These findings suggest that the implementation of GLIN is likely to change the treatment of children with chronic lung diseases that are more prevalent in underrepresented minorities, such as asthma.

Postpartum Hemorrhage after Vaginal Delivery Is Associated with a Decrease in Immediate Breastfeeding Success.

This study aimed to identify the impact of postpartum hemorrhage (PPH) after vaginal delivery on immediate breastfeeding success. This is a retrospective cohort study examining the impact of PPH on breastfeeding for nulliparous patients after term, singleton, vaginal deliveries at a large academic institution from 2017 to 2018. Indicators of successful breastfeeding in the immediate postpartum period were measured by the presence of breastfeeding, the need for formula supplementation, the average number of breastfeeding sessions per day, the average amount of time spent at each breastfeeding session, the average number of newborn stools and wet diapers produced daily, and the neonatal percentage in weight loss over the first 2 to 3 days of life. A total of 1,904 women met inclusion criteria during the study period, 262 (13.8%) of whom experienced PPH, defined as an estimated blood loss of 500 mL or greater after vaginal delivery. Women who had a PPH had significantly fewer breastfeeding sessions on average (β = -0.06, p-value 0.01) and required more time at each breastfeeding session (β = 0.08, p-value <0.002). Neonates of women with PPH had a larger percentage in weight loss over the first 2 to 3 days of life compared with those without PPH (β = 0.06, p = 0.008). Women who experience PPH after vaginal delivery have a decreased number of breastfeeding sessions despite spending more time trying to breastfeed, and an increased percentage in neonatal weight loss over the first 2 to 3 days of life. Further work is needed to elicit the mechanism behind this association; however, it is possible that PPH results in decreased secretion of endogenous oxytocin from the hypothalamic-pituitary axis as a result of hypovolemia. These women may therefore require additional breastfeeding support for successful breastfeeding initiation in the immediate postpartum period. · Women who experience PPH after vaginal delivery have decreased breastfeeding success.. · Further work is needed to elicit the mechanism behind this association.. · These women may require additional support for successful breastfeeding initiation postpartum..

Low rates of vaccination among atopic dermatitis, alopecia areata, psoriasis, and psoriatic arthritis patients on biologics.

Biologics and Janus kinase (JAK) inhibitors are immunomodulating and immunosuppressing medications utilized to treat atopic dermatitis (AD), psoriasis (PSO), psoriatic arthritis (PsA), and alopecia areata (AA). Special recommendations must be considered when prescribing vaccinations in this population, as the pneumococcal and herpes zoster vaccine are recommended to patients ≥ 19-years-old (rather than ≥ 65-years-old and ≥ 50-years-old as in the general population, respectively), along with a yearly influenza and up to date COVID-19 vaccination. Additionally, TNF-α and JAK-inhibitors may increase the risk of latent Hepatitis B virus (HBV) reactivation among high-risk patients. Prior to prescribing these medications, a quantitative HepB Surface Antibody (HepB SA) test is performed to determine immunity. This study utilized the SlicerDicer function on EPIC Medical Records to search for any patient ≥ 19-years-old prescribed a biologic or JAK inhibitor for AD, PSO, PsA, or AA between 10/2003 and 10/2023 at a large tertiary institution. Vaccination rates among patients on biologics and JAK inhibitors were low, with rates being significantly lower in patients 19-64 years-old, compared to those ≥ 65 years-old for most disease states (p < 0.01). Among AD, PSO/PsA, and AA patients, on average, 9.39% were vaccinated for influenza, 6.76% for herpes zoster, 16.56% for pneumococcal pneumonia, and 63.98% for COVID-19. Only 3.16% of patients were adequately vaccinated for HepB after an abnormal HepB SA test. Here, extremely low rates of vaccination among patients on biologics and JAK inhibitors at our institution were highlighted, emphasizing the imperative need for ensuring vaccination in this group.

Classification and management strategy of spontaneous carotid artery dissection

ObjectiveSpontaneous carotid artery dissections (sCADs) are the common cause of stroke in middle-aged and young people. There is still a lack of clinical classification to guide the management of sCAD. We reviewed our experience with 179 patients with sCAD and proposed a new classification for sCAD with prognostic and therapeutic significance. MethodsThis is a retrospective review of prospectively collected data from June 2018 to June 2023 of patients with sCAD treated at a large tertiary academic institution in an urban city in China. Based on imaging results, we categorize sCAD into four types: type Ⅰ, intramural hematoma or dissection with <70% luminal narrowing; type Ⅱ, intramural hematoma or dissection with ≥70% luminal narrowing; type Ⅲ, dissecting aneurysm; type ⅣA, extracranial carotid artery occlusion; and type ⅣB, tandem occlusion. We compared the clinical data and prognostic outcomes among various types of sCADs. ResultsA total of 179 patients and 197 dissected arteries met the inclusion criteria. The mean age of the 179 patients with sCAD was 49.5 years, 78% were male, and 18 patients (10%) had bilateral sCAD. According to our classification, there were 56 type Ⅰ (28.4%), 50 type Ⅱ (25.4%), 60 type Ⅲ (30.5%), and 31 type Ⅳ (15.7%) dissections. During a mean hospitalization length of 11.4 ± 47.0 days, there were nine recurrent strokes (4.6%) after medical treatment, two type Ⅲ dissections (1.0%), seven type Ⅳ dissections (3.6%), all ipsilateral, and one death. Overall, there were seven (3.6%, 1 type Ⅰ dissection, 3 type Ⅱ dissections, 2 type Ⅲ dissections, and 1 type Ⅳ dissection) recurrent strokes and three (1.5%, all type Ⅲ dissections) recurrent transient ischemic attacks in patients treated with just medical therapy during the follow-up period, all ipsilateral, with a mean follow-up of 26 months (range, 3-59 months). These patients did not undergo further intervention due to the high difficulty associated with endovascular treatment (EVT) or the mild nature of recurrent cerebral ischemic symptoms. Twenty-nine type I dissections (51.8%) were completely recanalized after antithrombotic therapy. A total of 19 type II dissections (38%) and 44 type III dissections (73%) received EVT for persistent flow-limited dissections, enlargement of dissecting aneurysms, or aggravation of neurological symptoms despite antithrombotic therapy. Type Ⅳ dissections are more likely to lead to the occurrence of ischemic stroke and presented with more severe symptoms. Eight type IVB dissections (33%) received acute phase intervention due to distal thromboembolism or aggravation of neurological symptoms after medical treatment. In terms of cerebral ischemic events and mortality, there were no statistically significant differences among the four types of sCAD (all P > .05). Favorable outcome was achieved in 168 patients (93.9%). ConclusionsThis study proposed a novel and more comprehensive classification method and the modern management strategy for sCAD. Antithrombotic therapy is beneficial to reduce the risk of recurrent stroke for stable sCAD. Non-emergent EVT can be an alternative therapeutic approach for patients who meet indications as in type II to IVA dissections. Urgent procedure with neurovascular intervention is necessary for some type IVB dissections. The short-term results of EVT for sCAD are encouraging, and long-term device-related and functional outcomes should undergo further research.

Research impact assessment: Developing and applying a viable model for the social sciences

Abstract Prompted by research funding agencies and regulatory bodies, universities need to demonstrate and manage the impact of their research. Therefore, models for evaluating research impacts that can be applied quickly and at a reasonable cost are needed. However, the development of these models presents considerable challenges: research impact is multidimensional and can occur over time because of multiple interactions between different agents. Furthermore, impact assessment can demand substantial time and resources. Considering this challenging context, this study proposes a research impact assessment model capable of optimizing benefits and costs. The model was based on a multidimensional impact perspective and an application-oriented way of generating and transmitting knowledge. It was applied to a large teaching and research institution with a predominant role in the social sciences. The assessment involved a survey of the leaders of 133 research projects. The main findings of the application of the assessment model were as follows: first, knowledge production is transitioning from a traditional mode (aimed to impact science) to a new mode (aimed to impact multiple stakeholders); second, project leaders still perceive the prevalence of scientific impact over other types of impact; and third, the survey revealed how certain characteristics of the knowledge production mode relate to (perceived) impact. The viable research impact assessment model was demonstrated to be useful and cost-effective; thus, with adaptations and improvements, it may be used by other institutions, particularly those with internal research funding programs. This article also presents the model’s limitations, suggesting directions for future research.

Chinese expert consensus on clinical practice of daytime hip arthroplasty

Daytime hip arthroplasty refers to a medical procedure where a patient undergoes admission, surgery, and discharge all within a single day (24 hours). The establishment of daytime hip arthroplasty centers signifies a significant paradigm shift in the development model of modern hospitals. While numerous nationally accredited large medical institutions are undertaking daytime hip arthroplasty in various forms and scales, there remains a lack of standardized system processes and criteria. In this context, the National Clinical Research Center for Geriatric Disorders (Xiangya Hospital), Bone and Joint Specialty Committee of the China Ambulatory Surgery Alliance, Joint Surgery Branch of the Chinese Orthopedic Association, and Osteoarthritis Study Group of the Chinese Association of Orthopedic Surgeons have collaboratively organized experts in the relevant field domestically. Leveraging international experiences in daytime hip arthroplasty and integrating them with the clinical practices of well-established medical institutions conducting daytime surgeries in China, they have arrived at consensus recommendations. These recommendations cover the establishment of daytime hip arthroplasty centers, policies, procedures, and perioperative management. The ultimate goal is to provide reference points and guidance for the standardized implementation of daytime hip arthroplasty.
