Abstract Background Community Paramedic (CP) programs use specially trained paramedics to provide healthcare in the community to increase access to care, reduce unnecessary emergency department visits, and improve timeliness of care. Mayo Clinic in Rochester, MN recently launched a CP Program to provide in-home care for patients who require regular intravenous medications, wound care, diuresis for heart failure, medication reconciliation, care plan compliance/education. CP utilizes i-STAT1 CHEM8+ and Lactate (CG4+) testing (Abbott Point of Care, Abbott Park, IL) to make therapy decisions primarily for heart failure patients based on rapid laboratory results. Having results available at the point of care (POC) eliminates delays between testing and treatments, expediting care for the patient. Prior to using i-STAT, CP traveled to the patient’s residence, drew blood tubes, delivered the tubes to Mayo Clinic, waited for test results, returned to the patient’s home, and provided treatment. In this observational study, we assessed the benefit of in-home POC i-STAT1 testing performed by our CP Program to improve patient care and increase efficiency. Methods Patients within a 40-mile radius of Mayo Clinic were eligible to receive CP service. Whole blood venous specimens were collected and tested using the i-STAT1 CHEM8+ metabolic panel cartridge according to manufacturer instructions to measure: ionized calcium, chloride, glucose, hematocrit, total carbon dioxide, blood urea nitrogen, creatinine, potassium, sodium, anion gap while the i-STAT1 CG4+ cartridge measures lactate. The laboratory information system was used to extract laboratory results, and Excel (Microsoft, Redmond, WA) was used to filter data and perform calculations. Results November 2022 through December 2024, CP performed testing with 353 i-STAT cartridges (3862 tests) on 102 unique patients who each had 1-12 separate orders. Patient ages were 25 to 97 years. 41.2% (1590/3862) of the individual results obtained were outside of our reference intervals (23.0% high, 18.0% low), with 10.8% being ionized calcium, 10.2% chloride, 10.3% glucose, 13.0% hematocrit, 7.6% total carbon dioxide, 18.2% blood urea nitrogen, 16.4% creatinine, 6.7% potassium and 6.9% sodium. Additionally, 0.13% of results were critically high (ionized calcium, potassium, and sodium) and 0.10% were critically low (potassium and ionized calcium). Hypokalemic patients were sent to the infusion therapy center for IV potassium. Patients experiencing hyperkalemia were retested and sent to the emergency department (ED). Hyponatremic and hypercalcemic patients were sent to the ED for further treatment. Abnormal (non-critical) results were reviewed by CP personnel to make treatment recommendations or medication adjustments. Conclusion i-STAT1 home testing performed by CP facilitated rapid therapeutic interventions and expedited decision-making. POC testing has increased the group’s efficiency—alleviating the need to transport specimens to the central laboratory and wait on test results before returning to the patient for treatment. Paramedicine emphasizes a proactive and preventative approach to medicine. We anticipate that this model of care and testing will expand to cover other chronic health conditions due to the program’s early success.

ABSTRACT Background and Objectives Neoadjuvant chemoimmunotherapy (NACI) for node‐positive breast cancer may induce immune cell activation in regional lymph nodes (LN), confounding post‐NACI imaging. Here we evaluated RECIST 1.1 criteria to predict post‐NACI pathologic LN status. Methods We studied patients with biopsy‐proven cN+ non‐distant metastatic breast cancer receiving NACI operated on 03/2020–09/2024 with both pre‐ and post‐NACI cross‐sectional imaging. Per RECIST 1.1, LN short axis diameter (SAD) was measured in target (defined as SAD ≥ 15 mm) and nontarget (SAD 10–14.9 mm) LNs. Groups were compared using Fisher′s exact test. Results 75 patients, median age 53 years, were studied: 61% cN1, 12% cN2, and 27% cN3. Baseline median number of imaging‐suspicious LN was 4 (IQR 2‐5). Post‐NACI, 64% had a nodal pathologic complete response (pCR/ypN0). 55% met RECIST 1.1 LN assessment criteria. 21 of 32 (66%) with an imaging CR (iCR) were ypN0, while 8 of 9 (89%) without an iCR were ypN0. Neither target ( p = 0.24) nor combined target/nontarget LN iCR ( p = 0.76) predicted ypN status. Nodal pCR rates were higher in those with ≤ 1 versus > 1 suspicious LN post‐NACI (71% vs. 42%, p = 0.03). Conclusions RECIST 1.1 criteria did not predict nodal pCR for NACI‐treated node‐positive breast cancer patients. Other post‐NACI imaging assessment strategies are needed.

OBJECTIVE The Centers for Medicare & Medicaid Services (CMS) requires a low C-peptide level for insulin pump coverage unless the individual is β-cell autoantibody positive, which precludes coverage of automated insulin delivery (AID) systems for many people with type 2 diabetes. RESEARCH DESIGN AND METHODS In the Randomized Trial Evaluating the Efficacy and Safety of Control-IQ+ Technology in Adults With Type 2 Diabetes Using Basal-Bolus Insulin Therapy study evaluating the t:slim X2 insulin pump with Control-IQ+ technology, adults with insulin-treated type 2 diabetes were categorized into high C-peptide (n = 195) and low C-peptide (n = 59) groups based on CMS criteria. RESULTS In the AID group, mean HbA1c decreased from baseline by 0.8%, which was significantly greater than in the control group with both high (P < 0.001) and low (P = 0.02) C-peptide levels. Results were similar in participants ≥65 years old. CONCLUSIONS The benefit of AID is present with high and low C-peptide levels. Thus, requiring a low C-peptide level as a prerequisite for AID therapy is not warranted.

Spousal caregivers of persons living with serious illnesses experience significant emotional and social challenges related to their caregiving role. The purpose of this study was to gain a deeper understanding of how spousal caregivers perceive current and anticipated losses associated with caring for a partner living with advanced cancer. Spousal caregiver participants engaged in semistructured interviews about their caregiving experiences and subsequent changes that occurred in their lives. Caregivers experienced social changes, emotional energy investment, and relationship changes as sources of grief. Social changes involved a loss of freedom and increased isolation, while emotional energy investment manifested as suppressed emotions and fears about the future. Relationship changes encompassed both positive and negative shifts in communication and roles. Targeted interventions, such as support groups and counseling, are essential to mitigate the negative impacts of caregiving and improve the well-being of older adult spousal caregivers.

Abstract Background and Aims Truncating variants in the TTN gene (TTNtv) are the most common genetic cause of dilated cardiomyopathy (DCM) but also occur as incidental findings in the general population. This study investigated factors associated with the clinical manifestation of TTNtv. Methods An international multicentre retrospective observational study was performed in families with TTNtv-related DCM. Shared frailty models were used to estimate associations of variant characteristics with lifetime risk of DCM, and logistic regression to estimate odds ratios (ORs) for individual-level clinical risk factor profiles (cardiac conditions, cardiovascular comorbidities, lifestyle) and DCM. Results A total of 3158 subjects in 1043 families with TTNtv-related DCM were studied. TTNtv-positive subjects were 21-fold more likely to develop DCM [OR, 21.21; 95% confidence interval (CI), 14.80–30.39]. Disease onset was earlier in males, but was similar for TTNtv of different types and locations. The presence of clinical risk factors was associated with earlier DCM onset (OR, 3.41; 95% CI, 2.06–5.64), with a prior history of atrial fibrillation having a two-fold increased odds of DCM (OR, 2.05; 95% CI, 1.27–3.32). The prevalence of clinical risk factors increased with age; however, the strength of the DCM association was greatest for young-onset (<30 years) disease (OR, 4.75; 95% CI, 2.35–9.60). Administration of beta-adrenergic receptor or renin-angiotensin system-blocking drugs prior to overt DCM was associated with 87% reduced odds of DCM (OR, .13; 95% CI, .08–.23). Conclusions Disease onset in TTNtv-associated familial DCM is dependent on individual patient context and is potentially modifiable by risk factor management and prophylactic therapeutic intervention.

BACKGROUND: To reduce technical variation in cancer surgery, the Commission on Cancer (CoC) recently implemented 6 operative standards as part of its national cancer center accreditation process. CoC sites are evaluated for compliance with these standards through scheduled visits conducted by trained site reviewers. We characterized site reviewers’ perspectives on the implementation of the operative standards. STUDY DESIGN: Twenty interviews were conducted with CoC site reviewers using a semistructured interview guide based on the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework. Themes were identified using thematic analysis mapped to the updated Consolidated Framework for Implementation Research. RESULTS: Site reviewers viewed the operative standards as an effective starting point for improving technical quality and were optimistic the standards would lead to positive change. Compliance was associated with supportive site leadership, effective interdisciplinary communication, and the availability of adequate personnel and institutional resources. In contrast, resistance from surgeons was identified as a key barrier. CoC site reviewers interpret their role as extending beyond assessing compliance, viewing themselves as advocates, educators, and partners to the sites. CONCLUSIONS: Overall, CoC site reviewers perceive the operative standards favorably. To enhance implementation of the operative standards, efforts should focus on modifiable institutional and individual-level factors, such as leadership support and surgeon engagement. Additionally, the multifaceted role of the site reviewers presents a valuable opportunity to improve compliance by formalizing the supportive relationship between reviewers and sites.

Introduction Patients hospitalized for headache treatment pose unique challenges to the healthcare system. Currently, there is a lack of evidence-based guidance on management. This practice advisory aims to fill this critical gap by systematically reviewing the existing literature and providing comprehensive, evidence-based recommendations for managing headache patients during hospitalization. Methods In February 2023, the American Society of Regional Anesthesia and Pain Medicine approved this practice advisory proposal. The steering committee selected committee members based on clinical and research expertise in the field of headache medicine. Nine questions were formulated by the committee, and each question was assigned to a group composed of 3–4 members. A systematic literature search for each question was performed in Medline, Embase, Cochrane Database of Systematic Reviews and Web of Science on June 21, 2023. The results from each search were imported into separate Covidence projects for screening, data extraction, and risk of bias assessment. Additionally, relevant systematic reviews (SR) were screened. Each group submitted a structured narrative review along with statements and recommendations based on the US Preventive Services Task Force (USPSTF) format for grading of evidence. While the USPSTF framework was used, including the language in the recommendations, the formal USPSTF methodology, including the SR with meta-analysis and summary tables with forest plots, was not followed because of low overall evidence quality. The interim draft was shared electronically with each collaborator, who was requested to vote anonymously using two rounds of the modified Delphi approach. A consensus recommendation required >75% agreement. Results The panel generated 12 statements and 17 recommendations, along with their strength and certainty of evidence. Following two rounds of Delphi voting, a high consensus was achieved for all statements and recommendations. Most statements received a low-to-moderate level of certainty, and all but one recommendation received grade B or C, which was consistent with the lack of randomized controlled trials supporting most of the drugs in this document. Conclusions This evidence-based practice advisory provides a foundational step toward standardizing inpatient headache care and highlights existing gaps in the literature that should be addressed through rigorous prospective randomized studies.

Pediatric central nervous system tumors are the leading cause of cancer-related deaths in children. The five-year survival rate for high-grade glioma in children is less than 20%. The development of new treatments is dependent upon multi-institutional collaborative clinical trials requiring reproducible and accurate centralized response assessment. We present the results of the BraTS-PEDs 2023 challenge, the first Brain Tumor Segmentation (BraTS) challenge focused on pediatric brain tumors. This challenge utilized data acquired from multiple international consortia dedicated to pediatric neuro-oncology and clinical trials. BraTS-PEDs 2023 aimed to evaluate volumetric segmentation algorithms for pediatric brain gliomas from magnetic resonance imaging using standardized quantitative performance evaluation metrics employed across the BraTS 2023 challenges. The top-performing AI approaches for pediatric tumor analysis included ensembles of nnU-Net and Swin UNETR, Auto3DSeg, or nnU-Net with a self-supervised framework. The BraTS-PEDs 2023 challenge fostered collaboration between clinicians (neuro-oncologists, neuroradiologists) and AI/imaging scientists, promoting faster data sharing and the development of automated volumetric analysis techniques. These advancements could significantly benefit clinical trials and improve the care of children with brain tumors.

Abstract We conducted this systematic review to evaluate outcomes of thrombolysis followed by anticoagulation vs anticoagulation alone in pediatric patients with venous thromboembolism (VTE). This systematic review addresses mortality, VTE resolution, recurrence, bleeding, and organ-specific outcomes in 5 PICO (population, intervention, comparison, outcomes) questions on thrombolysis across pulmonary embolism (PE), extremity deep vein thrombosis (DVT), right atrial thrombosis (RAT), cerebral sinus venous thrombosis (CSVT), and renal vein thrombosis (RVT). Meta-analysis reported risk ratios or differences (95% confidence intervals [CIs]), and absolute effects per 1000 patients. Certainty of evidence was assessed using GRADE (Grading of recommendation, assessment, Development, and Evaluation) guidelines. Thirteen nonrandomized studies were included and no randomized clinical trials addressed these questions. Thrombolysis might be associated with a higher risk of major bleeding, clinically relevant nonmajor bleeding, or unspecified bleeding with risk differences of 0.09 (95% CI, −0.06 to 0.23), 0.06 (95% CI, −0.11 to 0.22), and 0.09 (95% CI, −0.04 to 0.23), respectively. In PE with hemodynamic compromise, thrombolysis might be associated with a lower risk of mortality but conclusions on PE progression were uncertain in submassive PE. In DVT, thrombolysis may have little to no effect on mortality or thrombus resolution but might be associated with lower risk of postthrombotic syndrome. In RAT, thrombolysis might have little to no effect on thrombus resolution but a higher risk of major bleeding and mortality. For CSVT and RVT, the evidence was very limited. These findings were based on very-low-certainty evidence because of confounding and imprecision from small sample sizes. This systematic review highlights key challenges in developing recommendations for thrombolysis in children with VTE.
