Use of CAR T cell vs non-CAR T cell therapy in the treatment of patients (pts) with multiple myeloma (MM) in the Medicare population.

e23310 Background: Chimeric antigen receptor T-cell therapy (CAR T) is FDA-approved in pts with triple-class exposed (TCE) relapsed/refractory (RR) MM after four or more prior lines of therapy (LOTs). Real-world access to CAR T remains challenging due to manufacturing capacity, financial barriers, and pt fitness. Pts with certain pre-existing comorbidities (e.g., central nervous system disease, heart disease, secondary malignancies) are commonly excluded from clinical trials, including those investigating CAR T. The objective of this study was to identify the factors associated with the use of CAR T in pts with TCE RRMM to better understand the unmet need in this population. Methods: We conducted an observational cohort study using Medicare fee-for-service data; each pt in the CAR T intention-to-treat (ITT) population between 2021 and 2023 was matched to three non-CAR T pts, without replacement. Pts were eligible if they had an initial MM diagnosis, were continuously enrolled, were TCE, and did not receive treatment in a clinical trial. The index date was the ITT date. Baseline characteristics included age, sex, race/ethnicity, census region, three comorbidity indexes (Charlson, Elixhauser, CMS hierarchical condition categories [HCCs]), a claims-based frailty index (CFI), and dual enrollment in Medicare and Medicaid (as a proxy to social economic status [SES]). Logistic regression was used to derive odds ratios (ORs) and 95% confidence intervals (CIs) comparing the characteristics of CAR T vs non-CAR T pts. Results: Seventy-three ITT CAR T pts (nine underwent apheresis but did not receive CAR T) were matched to 219 non-CAR T pts by LOT and index year. Matched pts were treated with varied standard regimens (daratumumab-containing: 63%). Median prior LOTs were similar in the two cohorts (8; range 2–13). Median time from MM diagnosis to index date was 44.6 and 51.9 months for CAR T and non-CAR T pts, respectively. Compared with non-CAR T pts, pts in the CAR T population were younger (aged < 75 years: 59% CAR T vs 36% non-CAR T), less frail (mean CFI: 0.18 vs 0.20) and had higher SES (without dual enrollment in Medicare and Medicaid: 96% vs 81%), but were similar in terms of sex, region, and race/ethnicity. Variation in individual comorbidity prevalence was observed between CAR T and non-CAR T pts. In a multivariable regression analysis, factors strongly associated with lower odds of CAR T use included age ≥75 years (OR 0.29; 95% CI 0.16–0.53), comorbidities (lung/other severe cancers [OR 0.39; 95% CI 0.20–0.74] and chronic obstructive pulmonary disease [OR 0.32; 95% CI 0.10–0.99] defined by HCCs), and SES (OR 0.09; 95% CI 0.02–0.37). Conclusions: Older age, certain comorbidities, and lower SES are associated with lower odds of receiving CAR T in real-world pts with TCE RRMM, demonstrating an unmet need for more accessible and effective treatment options with acceptable safety profiles for these pts.

Expanding diversity in colorectal cancer studies with a focus on Hispanic and Latino participant enrollment.

e13532 Background: Colorectal cancer (CRC) is a leading cause of cancer mortality among Hispanic and Latino groups (Hispanic/Latinx). Despite making up 18.9% of the U.S. population, Hispanic/Latinx representation is only 2.3%-3.9% of subjects in oncology trials, highlighting the need for diversity in CRC research. Freenome is developing a blood test (MyTectCRC) intended to provide a convenient and accessible option for CRC screening. Its clinical validation will be supported by PREEMPT CRC, a prospective multi-center observational study. To ensure a diverse enrollment, Freenome partnered with several sites, including IHS, in communities with a diverse population. This analysis explores strategies used at IHS Health to effectively enroll minority groups. Methods: Initiated in 2020, PREEMPT CRC study (NCT04369053) enrolled participants aged 45-85 at average CRC risk. Eligible and consenting participants underwent a blood draw and a screening colonoscopy (CS), with the blood sample analyzed by Freenome using the investigational blood test. IHS Health, a research institute in Kissimmee, Florida, utilized a variety of methods to maximize the enrollment of diverse populations reflective of its local communities, such as partnering with local organizations to establish community outreach and employing bilingual staff to translate, educate, answer study questions, with cultural sensitivity. Participants were also able to have blood drawn and undergo CS on the same day due to its proximity to a gastroenterology office. Results: The site of IHS Health enrolled 427 participants in the PREEMPT CRC study, including substantial representation of Hispanic/Latinx (78.7%) which exceeded their proportional representation in the U.S. population. The self-reported race of enrolled participants was predominantly White (71.2%), with a significant proportion of Black or African American (24.1%). The age distribution showed higher enrollment for the 65-74 age group, emphasizing inclusivity for older populations characteristic of the catchment area. Participants exhibited healthy lifestyle behavior with the majority of the population abstaining from tobacco (88.8%), alcohol (84.1%) or drug use (99.5%). Participants were very receptive to the blood test/CS with all undergoing blood draw and 96% CS adherence. Conclusions: The results underscore the success of IHS Health's recruitment methods in addressing health disparity by emphasizing the importance of inclusivity in clinical trials, leading to high enrollment of Hispanic/Latinx, reflective of local demographics. Success of PREEMPT CRC study highlights the need for careful site selection, robust recruitment strategies, and practical accessibility for patients to ensure a comprehensive understanding of medical interventions across diverse populations.

Increased Time Interval of Postoperative Flap Monitoring After Autologous Breast Reconstruction

Background Hourly flap checks are the most common means of flap monitoring during the first 24 hours following autologous breast reconstruction (ABR). This practice often requires intensive care unit (ICU) admission, which is a key driver of health care costs and decreased patient satisfaction. This study addresses these issues by demonstrating decreased cost and length of admission associated with a 4-hour interval between flap checks during the first 24 hours following ABR. Methods This is a retrospective review of ABR surgeries performed by multiple surgeons from 2017 to 2020. Two cohorts were identified, one that underwent flap checks every hour in the ICU (Q1 cohort) and the other that underwent flap checks every 4 hours on the hospital floor (Q4 cohort). Our primary outcome measures were length of stay (LOS), flap takebacks, flap loss, and encounter cost. Results Rates of flap takeback and loss did not differ between cohorts (P = 0.18, P = 0.21). The Q4 cohort's average LOS was shorter than the Q1 cohort (P = 0.002). The Q4 cohort's average cost was also $25,554.80 less than the Q1 cohort (P < 0.001). This association persisted after controlling for LOS, operating room takeback, timing and laterality of reconstruction, and flap configuration (hazard ratio = 0.65, P = 0.0007). Conclusion This study demonstrates the benefits of lengthened flap check intervals during the first 24 hours following ABR. These intervals decrease the cost of ABR while also maintaining safety, making ABR a more accessible option for breast reconstruction patients.

Enrollment strategies to promote inclusion in a colorectal cancer screening study.

e13530 Background: Colorectal cancer (CRC) is the second deadliest cancer in the U.S. and while rates vary among racial/ethnic groups, the Black community is disproportionately impacted with the highest incidence and mortality rates. Notably, CRC rates have also been rising among younger individuals aged 45 to 49. Recruitment of diverse and underrepresented groups, such as the populations described above, is increasingly important to enhance generalizability and real world performance in clinical studies. Freenome is developing a blood-based test (MyTectCRC) with the aim of providing a convenient and accessible option for CRC screening. Clinical validation of MyTectCRC test will be supported by PREEMPT CRC, a prospective, observational, multi-center study. The aim of this analysis is to assess the use of community-based recruitment approaches in a diverse inner-city population in Brooklyn, New York. Methods: PREEMPT CRC enrolled subjects aged 45-85 who were at average risk for CRC. To ensure representation of ethnic groups that have historically been difficult to recruit, the study deliberately engaged sites delivering care in diverse communities. Moskowitz Practice recruited from a patient base consisting largely of city workers in Brooklyn, New York, and deployed several patient-focused, ease-of-access methods such as convenient location for colonoscopy (CS) in an ambulatory surgery center, direct patient education from the physician, direct patient support from attentive and engaged site staff, customizable scheduling and screening reminders, and patient-to-patient referrals. Notably, the same approach was used for all study candidates, regardless of the participant’s ethnic/racial representation. Results: Community-based approaches contributed to strong participation from the site’s community in PREEMPT CRC. Importantly, the participants were representative of the local population with 87.4% of the enrollees identified as Black, a group historically underrepresented in oncology studies. The site also successfully enrolled young participants aged 45 to 50 (20.5%) and more females (58.2%) than males. Participants had relatively healthy lifestyles with 91.4% reporting as non-smokers, and 65% reporting no alcohol use. Study participants were highly compliant with study required procedures such as blood collection (100%) and CS (95%). Conclusions: The community-specific methods utilized by the site helped contribute to the diversity enrollment in PREEMPT CRC while recruiting participants that are representative of the local community. Ensuring diversity in clinical studies is the beginning to promoting equity in CRC screening, diagnosis and treatment. A blood-based test, supported by clinical evidence built on data from a diverse and representative population, may provide a convenient and accessible option for CRC screening and potentially increase the screening rate and reduce the CRC burden.

Decentralized trial recruitment methods to facilitate broad coverage across urban and rural counties for a blood-based test in early colorectal cancer detection.

1607 Background: Based on the 2022 census, 20% of the U.S. population lives in rural areas. Recent literature suggests that individuals in these areas may encounter health disparities, potentially leading to higher mortality from colorectal cancer (CRC) when compared to their urban counterparts. The PREEMPT CRC is a prospective, multicenter clinical study designed to validate an investigational blood test (MyTectCRC) intended to provide a convenient and accessible option for CRC screening. PREEMPT CRC included a decentralized clinical trial (DCT) site to broaden enrollment from a wider range of geographical areas, including traditionally underrepresented rural regions. This analysis evaluates demographic characteristics of participants from rural and urban areas enrolled in two distinct strategies within the DCT sites. Methods: Eligibility criteria for PREEMPT CRC have been previously described (NCT04369053). All DCT activities occurred under one clinical study ‘Metasite’, enabled by a multichannel recruitment strategy that included 1) Direct-to-Participant (DTP) via digital enrollment and 2) Site-Based (SB) partners who supported the principal investigator by identifying participants scheduled to receive a screening colonoscopy. Participant zip codes were mapped to local counties and aligned with either 1) Metropolitan (Urban) or 2) non-Metropolitan (Rural) counties. Enrolled participants were analyzed for demographics and lifestyle behaviors such as tobacco, alcohol, and drug use. Results: The DCT site enrolled 12,137 participants, where 7,634 used DTP and 4,503 used SB. Of all DCT participants, 24.4% resided in rural areas. DTP's rural population recruitment (27.8%) was double that of the SB (13.5%). The female and male distribution was similar across the groups. A larger percentage of participants from underrepresented races overall were enrolled from urban areas; however, there were some noticeable trends in the rural population. For participants who resided in rural areas and reported their race, 12.5% of DTP participants were Black and 1.2% were Asian, compared to 9.6% and 1.2%, respectively, in SB. For participants in rural areas who reported ethnicity, within DTP, 5.1% identified as Hispanic/Latinx, compared to 14.3% Hispanic/Latinx in SB. Lifestyle behavior factors were similar between DTP and SB participants who resided in rural and urban areas. Conclusions: Through the use of a DCT, the PREEMPT CRC study reached rural areas especially through DTP methodology. Furthermore, the use of SB versus DTP showed certain shifts in demographics, these differences highlight the effectiveness of targeted outreach strategies and reflect the importance for integration of multiple methods and tools to enhance essential population characteristics across geographical locations.

Real-world multi-target stool DNA adherence in an underserved and vulnerable prison patient population.

e15632 Background: In 2024, colorectal cancer (CRC) is estimated to be the fourth most diagnosed cancer, as well as the second leading cause of cancer death in the United States. While adherence to regular CRC screening has been suboptimal in the general population, this holds to be especially true in populations that are medically underserved. Non-invasive tests, such as the guideline recommended multi-target stool DNA (mt-sDNA) test, offer a more accessible option to increase screening participation in difficult to reach populations. Herein, we evaluated adherence to CRC screening in a cohort of prisoners who received the mt-sDNA test at a Nebraska Department of Corrections facility in Nebraska. Methods: This was a retrospective cohort study in a small prison population. Participants included both males and females between the ages of 45 and 75 years who underwent CRC screening evaluation at the prison’s medical center between June 1st – December 31st, 2023 and were offered multiple CRC screening options, including the mt-sDNA test. No inducements were provided for completion of the mt-sDNA test. Baseline demographics were collected for cohort description. The primary variable of interest was mt-sDNA test return rate (adherence), defined as completion of the mt-sDNA test within 60 days of kit receipt. We also evaluated mt-sDNA test results in secondary analyses. Results: Once inclusion criteria were applied, the resulting analysis cohort included 129 patients who were first time mt-sDNA screeners. The cohort was largely male (96.9%) and between the ages of 50-64 years (78.3%). Overall mt-sDNA test adherence was 95.3%, with the average time to test completion being 20 days. No significant difference was seen in test completion among males and females (95.2% vs 100%, respectively). Completion rates increased with patient age, at 90.9% (45-49 years), 95% (50-64 years), and 100% (65-75 years). The shortest time to completion in the population was observed amongst patients who were females (18.8 days), and those between the ages of 45-49 years (17.1 days). Negative and positive mt-sDNA test results were observed in 82.9% and 17.1% of the cohort, respectively. Conclusions: CRC screening with the mt-sDNA test in this single-center study of incarcerated participants yielded exceptionally high adherence rates within 60 days of kit receipt. Assessment of follow up colonoscopy rates for test-positive participants is ongoing. While based on a relatively small sample size in this initial study, the mt-sDNA test exhibited favorable completion rates in a difficult to reach population, supporting further efforts to characterize patient, provider, and system-level benefits that may be obtained through broader adoption of this highly accessible screening approach in this challenging healthcare setting.

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.

The Implementation of Artificial Intelligence in Breast Cancer Screening

Breast cancer screening is traditionally administered by radiologists through mammography. Most women should be receiving mammograms once they reach their 40s to detect any signs of cancer early, especially those with high risk. Recently, the development of AI in medicine has proven to be useful in several fields, one of which is breast cancer screening. This literature review looks into the current status of AI in this field and evaluates different models of different types that could contribute to diagnosing breast cancer. The methodology used was searching key terms on the database PubMed, and then compiling and organizing papers into a table that highlighted similar results, which were summarized and analyzed. It was found that AI has the potential to be an accessible option. Deep learning, in particular, has seen the most experimentation. The advantages of using this technology include using it as a complementary tool for double reading, improving the time efficiency for the radiologists without losing accuracy, and its inclusivity throughout all populations. However, there are still limitations because many proposals themselves discuss the work that needs to be done before they can be generalized. External validation studies haven’t yielded ideal results, exposing the complications of using AI. Ethics of using this technology are also important to consider because AI is replacing human tasks. Implementing AI in a prominent role in breast cancer screening should take more examination, but promising developments have already set the framework.

A Pilot Study on Dietary Choices at Universities: Vending Machines, Canteens, and Lunch from Home.

Commercial environments and food acquisition methods significantly shape dietary practices and impact health. This study assesses dietary choices among Portuguese university students regarding vending machines, canteens, and lunches from home. It also evaluates their use of the university canteen and their tendency to bring lunch from home. This pilot cross-sectional study used a self-administered electronic questionnaire, made available in early 2023. Participants were recruited through snowball sampling. The study included 137 students from Portuguese higher education institutions, mainly women (74.5%), pursuing degrees or integrated Master's degrees (83.2%), primarily in health-related fields (55.5%). The median age was 21 years (20 to 23.5 years). About 70.0% regularly consumed food from vending machines, while approximately 60.0% brought lunch from home, avoiding the canteen. Factors such as convenience (48.5%), price (47.5%), product availability (40.6%), and taste (39.6%) mainly influenced vending machine choices. Monthly, chocolates, water, coffee, cookies, treats, and soft drinks were the most commonly acquired items, with coffee being the most frequent daily purchase. These findings provide insights for creating policies and initiatives to promote healthier and more accessible food options for students and strategies to encourage positive eating behaviors.

A Holistic In Silico and In Vivo Approach to Exploring the Antidiabetic, Antioxidant, and Hepatoprotective Properties of Rose of Sharon.

Diabetes mellitus (DM) is a significant global health burden that necessitates the exploration of effective and accessible therapeutic options. Phytotherapy has played a vital role in healthcare, with plant extracts being integral to traditional medicinal practices. The therapeutic potential of Hibiscus syriacus (Rose of Sharon), a plant with a rich ethnobotanical history, in the management of DM and its associated complications was investigated. In this study, the therapeutic potential of Hibiscus syriacus L. extract (HSE) against DM in streptozotocin (STZ)-induced diabetic rats was assessed, focusing on its effects on glucose regulation, antioxidative defense, and liver protection. The administration of the HSE extract substantially reduced hyperglycemia and increased insulin production, with concurrent improvements in body weight and hydration. The enhanced activity of antioxidant enzymes, such as superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), suggests reduced oxidative stress, which is further supported by molecular docking results with the 3GTV superoxide dismutase enzyme, showing a binding energy of -6.3 kcal/mol. A decrease in MDA levels also indicates a reduction in oxidative stress. Notably, HSE treatment led to decreased aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels and improved lipid profiles, indicating its hepatoprotective and lipid-modifying benefits. These findings support the inclusion of HSE as an adjunctive therapy in DM management strategies. This study promotes the consideration of Hibiscus syriacus L. therapeutic properties in global health contexts.

Dilip's Transmucosal Internal Sphincterotomy: A Simplified Approach to Lateral Internal Sphincterotomy for Fissure in Ano.

Fissure in ano is a prevalent and painful condition, typically treated by lateral internal sphincterotomy after conservative measures fail. Dilip's transmucosal internal sphincterotomy introduces a simplified approach that reduces the risk of damaging the external sphincter, making it particularly suitable for less experienced surgeons. This innovation offers a less invasive method with minimal risk of incontinence, providing a safer, more accessible option. Transmucosal internal sphincterotomy simplifies the internal sphincterotomy process, offering a tailored approach that eliminates the need for extensive dissection. This method allows surgeons complete control over the internal sphincter bundle, facilitating a precise, customizable cut without the risks associated with traditional internal sphincterotomy, especially in obese patients where the intersphincteric groove is not visible, leading to potentially harmful blind incisions. The procedure is performed under saddle block anesthesia with the patient in the lithotomy position. A distinctive approach involving the use of retractors and stay sutures allows the internal sphincter to be made prominent and secured without extensive dissection. The division of the internal sphincter is achieved through a minimal mucosal incision, requiring no closure and significantly reducing postoperative pain and complications. Between December 2020 and February 2022, 124 patients received transmucosal internal sphincterotomy, showing significant benefits with a median operative time of 7 minutes and low postoperative pain. With a 2.5% infection rate effectively managed and a 3% transient incontinence rate, the majority healed within 9 weeks. Recurrence was rare at 1.6%. Transmucosal internal sphincterotomy presents significant advantages over traditional internal sphincterotomy, including reduced pain, lower risk of complications, such as hematoma, abscess, or fistula formation, and the absence of painful postoperative nodules. The success of transmucosal internal sphincterotomy suggests that it should be incorporated into surgical education, offering a less daunting and more reproducible method for treating fissure in ano that is especially beneficial for junior surgeons and improving patient outcomes.

Vascular Access Considerations in Home Hemodialysis.

There is a global interest in expanding home dialysis utilization among patients with ESKD. Home hemodialysis (HHD) is an appealing KRT option for this population because of its multiple clinical and quality of life benefits. Central to successful HHD is the establishment and maintenance of a functioning vascular access that serves as a patient's lifeline while on therapy. While the selection of a vascular access type is influenced by individual patient circumstances, the arteriovenous fistula is generally the preferred access method. Training patients to use their dialysis access requires attention to safety, risk management, and monitoring for complications to minimize adverse events and technique failure. Policies incorporating systematic frameworks for quality improvement and assurance, in conjunction with the measurement of metrics relating to vascular access, are tools that should be used by HHD programs to enhance the value of care delivered. In this perspective, we aim to describe what is currently known about the various vascular access options in HHD and to elucidate what needs to be taken into consideration in the selection and care of this access.

Associazione Nazionale Medici Cardiologi Ospedalieri (ANMCO) scientific statement on the simplification of the drug regimen for secondary cardiovascular prevention.

The issue of suboptimal drug regimen adherence in secondary cardiovascular prevention presents a significant barrier to improving patient outcomes. To address this, the utilization of drug combinations, specifically single pill combinations (SPCs) and polypills, was proposed as a strategy to simplify treatment regimens. This approach aims to enhance treatment accessibility, affordability, and adherence, thereby reducing healthcare costs and improving patient health. The document is an Associazione Nazionale Medici Cardiologi Ospedalieri (ANMCO) scientific statement on simplifying drug regimens for secondary cardiovascular prevention. It discusses the underuse of treatments despite available, effective, and accessible options, highlighting a significant gap in secondary prevention across different socio-economic statuses and countries. The statement explores barriers to implementing evidence-based treatments, including patient, healthcare provider, and system-related challenges. The paper also reviews international guidelines, the role of SPCs and polypills in clinical practice, and their economic impact, advocating for their use in secondary prevention to improve patient outcomes and adherence.

Percutaneous Retrograde Trans-Gluteal Embolization of Type 2 Endoleak Causing Iliac Aneurysm Enlargement after Endovascular Repair: Case Report and Literature Review.

Late type II endoleaks (T2ELs) arising from the internal iliac artery (IIA) may present during follow-up after endovascular aortic repair (EVAR) of aortoiliac aneurysm and may warrant embolization if enlargement of the aneurysmal sac is demonstrated. When coverage of the IIA ostium has been made due to extensive iliac disease, access options can be challenging. Different treatment options have been reported over recent years, and a careful selection of the best one must be made based on the characteristics of each case. The present study reports a simple and reproducible sheathless percutaneous superior gluteal artery (SGA) access and provides a discussion based on a review of the existing literature on this topic.

Improvements in motor control are associated with improved quality of life following an at-home muscle biofeedback program for chronic stroke.

Chronic stroke survivors with severe arm impairment have limited options for effective rehabilitation. High intensity, repetitive task practice (RTP) is known to improve upper limb function among stroke survivors who have some volitional muscle activation. However, clients without volitional movement of their arm are ineligible for RTP-based interventions and require hands-on facilitation from a clinician or robotic therapy to simulate task practice. Such approaches can be expensive, burdensome, and have marginal effects. Alternatively, supervised at-home telerehabilitation using muscle biofeedback may provide a more accessible, affordable, and effective rehabilitation option for stroke survivors with severe arm impairment, and could potentially help people with severe stroke regain enough volitional activation to be eligible for RTP-types of therapies. Feedback of muscle activity via electromyography (EMG) has been previously used with clients who have minimal or no movement to improve functional performance. Specifically, training to reduce unintended co-contractions of the impaired hand using EMG biofeedback may modestly improve motor control in people with limited movement. Importantly, these modest and covert functional changes may influence the perceived impact of stroke-related disability in daily life. In this manuscript, we examine whether physical changes following use of a portable EMG biofeedback system (Tele-REINVENT) for severe upper limb hemiparesis also relate to perceived quality of life improvements. Secondarily, we examined the effects of Tele-REINVENT, which uses EMG to quantify antagonistic muscle activity during movement attempt trials and transform individuated action into computer game control, on several different domains of stroke recovery. For this pilot study, nine stroke survivors (age = 37-73 years) with chronic impairment (Fugl-Meyer = 14-40/66) completed 30 1-hour sessions of home-based training, consisting of six weeks of gaming that reinforced wrist extensor muscle activity while attenuating coactivation of flexor muscles. To assess motor control and performance, we measured changes in active wrist ranges of motion, the Fugl-Meyer Assessment, and Action Research Arm Test. We also collected an EMG-based test of muscle control to examine more subtle changes. To examine changes in perceived quality of life, we utilized the Stroke Impact Scale along with participant feedback. Results from our pilot data suggest that 30 sessions of remote training can induce modest changes on clinical and functional assessments, showing a statistically significant improvement of active wrist ranges of motion at the group level, changes that could allow some people with severe stroke to be eligible for other therapeutic approaches, such as RTP. Additionally, changes in motor control were correlated with the perceived impact of stroke on participation and impairment after training. We also report changes in corticomuscular coherence, which showed a laterality change from the ipsilesional motor cortex towards the contralesional hemisphere during wrist extension attempts. Finally, all participants showed high adherence to the protocol and reported enjoying using the system. Overall, Tele-REINVENT represents a promising telerehabilitation intervention that might improve sensorimotor outcomes in severe chronic stroke, and that improving sensorimotor abilities even modestly may improve quality of life. We propose that Tele-REINVENT may be used as a precursor to help participants gain enough active movement to participate other occupational therapy interventions, such as RTP. Future work is needed to examine if home-based telerehabilitation to provide feedback of individuated muscle activity could increase meaningful rehabilitation accessibility and outcomes for underserved populations.

Poland's first vascular access team 3-year analysis: Insights and learnings.

During the COVID-19 pandemic, Poland saw a surge in interest in midline catheters (MCs) and Long Peripheral Catheters (LPCs) for intravenous therapy. Before this, MCs were not extensively utilised in the country, and there was no formally established Polish vascular access team. MCs, which have been used for years in many countries, are now becoming increasingly common in Poland. This study aimed to analyse the use of MCs in a 3-year perspective of their introduction in daily clinical practice based on a nurse-led Vascular Access Team (VAT). The records of adult patients who received intravenous therapy with 727 MCs and 293 LPCs from January 2021 to December 2023 at the University Clinical Centre of the Medical University of Warsaw were analysed. The main indication for cannulation was expected intravenous therapy over 5 days (81.66%, n = 833), of which 71.37% (n = 728) of patients in this group had concomitant difficult intravenous access (DIVA). Over 6 years, centrally inserted central catheters (CICCs) inserted due to DIVA were reduced from n = 108 in 2017 to n = 18 in 2023. The end of intravenous therapy was the reason for the removal of 64.6% of catheters (n = 659), including death and switch to CICCs as well. Complications leading to premature removal accounted for 31.2%, such as: occlusion (14.6%), patient self-removal (7.1%) and thrombosis (3.43%). The introduction of MCs as a possible option for peripheral venous access reduces the use of CVCs. Developing MCs programmes should be based on investing in staff competencies, which increases success rates. The nurses and physicians should be trained in infusion care to achieve better results in the use of MCs and LPCs. Increasing the competence of nurses in Poland is necessary for the implementation of full-service and top-level functioning of VAT.

ANMCO Scientific statement on combination therapies and polypill in secondary prevention

The issue of suboptimal drug regimen adherence in secondary cardiovascular prevention presents a significant barrier to improving patient outcomes. To address this, the utilization of drug combinations, specifically single pill combinations (SPCs) and polypills, was proposed as a strategy to simplify treatment regimens. This approach aims to enhance treatment accessibility, affordability, and adherence, thereby reducing healthcare costs and improving patient health. The document is an ANMCO scientific statement on simplifying drug regimens for secondary cardiovascular prevention. It discusses the underuse of treatments despite available, effective, and accessible options, highlighting a significant gap in secondary prevention across different socioeconomic statuses and countries. The statement explores barriers to implementing evidence-based treatments, including patient, healthcare provider, and system-related challenges. The paper also reviews international guidelines, the role of SPCs and polypills in clinical practice, and their economic impact, advocating for their use in secondary prevention to improve patient outcomes and adherence.

Attitudes towards Telemedicine among Pregnant People and Parents of Toddlers in an Urban Safety-net Setting

Abstract: Objective. To understand attitudes towards telemedicine and to further elucidate benefits, disadvantages, and visit preferences in a largely minority, urban safety-net setting. Methods. Between 2020 and 2021, pregnant people, and parents of children younger than two years old were recruited from outpatient clinics. Interviews were conducted via phone, recorded, transcribed, and translated. Data were analyzed using content analysis. Results. Seventy-four (74) individuals participated including 42 pregnant people and 32 parents. Most participants cited advantages to telemedicine including safety, convenience, improved access, and less disruption of work schedules, and wished to continue to have the telemedicine option available after the pandemic. Conclusions. Patients seeking care in safety-net settings, many of whom are working parents, noted that telemedicine improves access to care by providing an efficient and accessible option that overcomes barriers related to transportation and work schedules. Their experiences highlight the importance of continuing to offer telemedicine services.

Variables Leading to Usage of Alteplase Versus Heparin Lock in Patients With Tunneled Catheters in Hemodialysis Care Project Centers, Saudi Arabia.

A hemodialysis tunneledcatheter is one option for vascular access used with hemodialysis patients; however, catheter complications such as thrombosis are still inevitable. To prevent thrombosis formation, a catheter-locking solution is instilled between dialysis sessions. Heparin is used as a default locking solution in our Hemodialysis Care Project centers, while arecombinant tissue plasminogen activator (rt-PA) such as alteplase is used to treat suspected catheter thrombosis. This study aimed to identify the clinical factors, catheter brands, and hemodialysis variables that influence the choice of use for alteplase versus heparin, for those patients with tunneled catheters, and reduce overprescribing of high-alert medication alteplase. A retrospective medical chart review study was conducted involving 230 patients with tunneled catheters; the first group of 133 patients used alteplase regularly three times a week, while the second group of 97 patients completed at least one year using the same catheter access with heparin lock only. Multivariate logistic regression and logistic regression analysis showed a significant association (p < 0.05) between different variables. Results suggest that overweight and hyperlipidemia patients are more likely to use alteplase. Patients using brand-name catheters such as Hemostar/Vas-cath (BD, Franklin Lakes, NJ) are less likely to use heparin than those using Medcompcatheters (Medcomp, Yuma, AZ). In addition, patients having a history of angioplasty would be less likely to have heparin than no angioplasty. Moreover, if the patient's fluid removal were equal to or less than 2 kg, they would be more likely to use heparin and vice versa. The study postulates that identified variables affect whether alteplase or heparin is used in hemodialysis tunneled catheters, and may be useful to increase awareness, improve practices, or judiciously control the use of alteplase within Saudi Arabia and globally.
