Background: Fecal immunochemical tests (FITs), fecal occult blood tests (FOBTs), and multitarget stool DNA (mt-sDNA) tests are convenient, noninvasive colorectal cancer (CRC) screening strategies. However, delays in or failure to complete follow-up colonoscopy (FU-CY) after a positive noninvasive test are associated with higher CRC incidence, complications, and mortality. We sought to evaluate FU-CY rates, time to colonoscopy, and compliance predictors. Patients and Methods: This retrospective cohort study linked 2 data sources: Komodo Health Data with Exact Sciences Laboratories. Data were collected from January 2016 to June 2023 and analyzed in 2024. Study participants (ages 45–75 years) were individuals with positive stool-based CRC screening tests (FIT, guaiac-based FOBT, or mt-sDNA tests). FU-CY compliance was assessed at 30-day intervals up to 365 days, and logistic regression was used to identify predictors of FU-CY. Results: Among 362,646 participants, colonoscopy compliance was 77.1% for mt-sDNA and 45.1% for FIT/FOBT ( P <.001). Overall FU-CY compliance was lowest among Asian and Black populations, but was significantly higher in these subgroups for mt-sDNA versus FIT (Asian: 74.2% vs 41.1%; Black: 71.3% vs 44.6%). The strongest predictor of compliance was use of mt-sDNA (odds ratio, 3.98; P <.001). More than half of participants across all race groups who completed FU-CY after mt-sDNA did so within the first 120 days, whereas none of the FIT/FOBT racial subgroups reached 50% completion within 365 days. Conclusions: Timely completion of colonoscopy after a noninvasive test is critical, as failure to undergo colonoscopy or delays in completion are associated with increased CRC incidence and more advanced-stage disease. These findings demonstrate that mt-sDNA use may help close CRC screening disparity gaps compared with FIT testing. FU-CY adherence is higher, and time to colonoscopy is shorter following a positive mt-sDNA test versus FIT across all racial and ethnic subgroups.

Background Surgeons face elevated risks of musculoskeletal disorders due to prolonged operating times, awkward postures, and repetitive tasks, which can impair performance and well-being. Microbreaks have emerged as a potential ergonomic intervention to reduce discomfort and fatigue during surgery. Objective The main goal of this study was to investigate and compare the intraoperative usability and effectiveness of two break scheduling strategies using the OR-Stretch TM Web-App. Furthermore, surgeons’ feedback on the primary barriers to implementation of the OR-Stretch Web-App was recorded. Methods This study used a randomized, within-subjects crossover design. Fourteen surgeons (eight females) performed three surgical procedures with the following microbreak schedules; (1) microbreaks every 30 min with an optional ten-minute snooze (Break-30), (2) microbreaks every 60 min with an optional ten-minute snooze (Break-60), or (3) no microbreaks (Baseline). Outcomes were measured using self-reported subjective surveys (e.g., discomfort, fatigue, workload, and usability). Results Surgeons found both Break-30 and Break-60 conditions aided physical performance, mental focus, body pain/discomfort, and level of fatigue (self-reported improvement between 28.6% and 78.6%). No significant differences were observed in surgeons’ subjective evaluations of the Break-30 and Break-60 conditions; however, the data suggest that Break-60 is preferable to the Break-30 condition. Conclusions This study provides evidence supporting the OR-Stretch Web-App as a potential surgical ergonomic intervention. However, enhancing the Web-App's user-friendliness and developing strategies to synchronize microbreaks with appropriate times during surgeries, to avoid disrupting the surgical workflow, are critical areas for future studies.

SignificanceCurrent clinical care following ischemic stroke provides intermittent assessments, potentially missing early detection of neurological deterioration. Optical imaging offers the potential for a continuous, portable alternative to the current combination of physical exams and radiological imaging. However, optical imaging technology has lacked the crucial combination of portability, resolution, and coverage required to assess spatially distributed brain function.AimHere, we present a proof-of-principle study that applies recent advancements in portable high-density diffuse optical tomography (HD-DOT) instrumentation and a functional connectivity analysis strategy to assess spatially distributed brain connectivity. Point-of-care brain health assessments with these tools may inform clinical care and our understanding of brain injury throughout acute stages of stroke recovery.ApproachWe measured spatially distributed cortical oxygenation with HD-DOT within the intensive care unit in N=13 patients with ischemic stroke within the first 72-h since last known normal. To assess brain function integrity, we developed a Similarity metric of functional connectivity (FC) through comparisons to FC in a healthy young adult population. To assess the sensitivity of this FC Similarity metric to disruptions caused by stroke, we compared these data with FC Similarity assessed in an older healthy cohort. We administered the NIH Stroke Scale to stroke patients to evaluate the potential of the FC Similarity metric to inform the severity of functional disruptions.ResultsThe FC Similarity metric applied to HD-DOT data in both acute stroke patients and healthy older controls exhibited a significant sensitivity to the presence of a stroke (Cohen’s d=1.5, p=1.2×10−3) and a significant relationship with the degree of neurological disruption as measured by the NIH Stroke Scale (R2=0.69, p=4.7×10−4).ConclusionsWe present a proof-of-principle for HD-DOT and the FC Similarity metric for assessing brain function during the acute stage of ischemic stroke recovery at the point-of-care.

Abstract Background and Aims Clinical models incompletely capture the molecular pathways driving heart failure (HF) progression. This study evaluated whether molecular risk stratification provides incremental prognostic information beyond established clinical predictors in patients with HF. Methods A total of 2432 patients from the Global Congestive Heart Failure (G-CHF) registry with available genotyping, DNA methylation, and proteomic profiling were analysed. Three molecular scores were assessed: a composite cardiovascular polygenic risk score (PRS) from DNA sequence polymorphisms, a methylation risk score (MRS) derived from epigenome-wide associations, and a 23-protein-based score (ProteomicDeath23). Each score was tested individually and in combination with the clinical Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) risk score and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels for mortality prediction. Validation was performed in an HF subset of the UK Biobank (UKB). Results Over a median follow-up of 3.0 years in G-CHF, 523 patients died from any cause (7.64 per 100 person-years [PY]). In multivariable analyses, ProteomicDeath23 was the strongest independent predictor of all-cause mortality (hazard ratio [HR] per 1 standard deviation, 2.23), outperforming NT-proBNP (HR 2.00), MRSMortality (HR 1.66), PRSmetaCVD (HR 1.10), and the MAGGIC score (HR 1.70). A model combining ProteomicDeath23 with MAGGIC and NT-proBNP achieved the highest discrimination for mortality (C-index, 0.77). Addition of MRSMortality to this proteomic-clinical model resulted in only small improvements in discrimination (ΔC-index, +0.004, P = .0039), while the PRSmetaCVD provided no incremental benefit. Among patients with low NT-proBNP/MAGGIC score, mortality rates increased from 1.71 to 8.12 per 100 PY across ProteomicDeath23 tertiles. Consistent results were observed in the UKB-HF validation cohort. Conclusion A proteomic score was the strongest molecular predictor of mortality in HF. Integrating proteomic signatures with clinical risk factors significantly improved risk prediction.

Objectives Comparing clinical outcomes after cardiopulmonary bypass with hemodsorption (HA) versus cardiopulmonary bypass without HA in patients undergoing cardiac surgery in terms of mortality and major complications. Methods PubMed, Scopus, and Web of Science databases were searched for relevant randomized control trials (RCTs) that compared postoperative clinical outcomes between patients receiving intraoperative HA with cardiopulmonary bypass versus patients receiving cardiopulmonary bypass without intraoperative HA in cardiac surgery. Results Sixteen RCTs with 851 patients (433 in the HA group and 418 in the control group), were included in our meta-analysis. Our meta-analysis found no significant differences between the intraoperative HA group and the control group in patients undergoing cardiac surgery in terms of 30-days/in-hospital mortality, new-onset atrial fibrillation, stroke or cerebrovascular events, postoperative delirium, renal failure/acute kidney injury, need for renal replacement, postoperative liver dysfunction, thrombocytopenia, bleeding, volume of blood loss, pneumonia, sepsis, respiratory insufficiency, duration of postoperative ventilation, distributive/septic shock, pericardial tamponade, need for extracorporeal membrane oxygenation (ECMO) support, sequential organ failure assessment (SOFA) score at ICU admission, plasma-free hemoglobin levels, and fibrinogen levels. However, the pooled analysis showed a significant association between HA and decreased albumin at ICU admission (MD = − 0.28, 95% CI [0.55 to 0.01], p -value = 0.04), decreased length of ICU stay (MD = −0.66, 95% CI [−1.24 to 0.08], p -value = 0.03), and decreased length of hospital stay (MD = −0.99, 95% CI [−1.88 to −0.10], p -value = 0.03). Conclusion Our findings suggest that there is not enough evidence to endorse the role of routine intraoperative HA during cardiopulmonary bypass in improving clinical outcomes after cardiac surgery. Factors such as patient risk profile, procedure complexity, and cost implications should be taken into account when considering this adjunct therapy.

Importance Opioid prescribing has decreased in the US for more than a decade. However, less is known about how prescribing trends differ by prescriber specialty and separately for short-term and long-term opioid prescribing for which the indications, clinical decision-making, and potential for harm vary substantially. Objective To characterize opioid analgesic prescribing trends in the US between January 1, 2010, and December 31, 2024, by prescriber specialty, analyzing short-term and long-term opioid use episodes separately. Design, Setting, and Participants This cross-sectional study used administrative claims data for commercially insured and Medicare Advantage patients (aged ≥65 years and &amp;lt;65 years with long-term disability) with at least 90 days of enrollment in medical and prescription coverage. Statistical analysis was performed from May 2025 to September 2025. Main Outcomes and Measures Prescribing volume, daily dose, and prescription duration. Results The study identified 110 288 218 opioid fills by 14 959 612 patients during the 15-year study period. Among opioid fills, 59.4% were attributed to female patients; the median (IQR) age at opioid fill was 61 (50-71) years. From 2010 to 2024, decreases in opioid prescribing were greater for long-term than short-term opioid use episodes (eg, commercial cohort: 81.3% reduction [from 33.2 fills per 100-person years in 2010 to 6.2 in 2024] and 74.6% reduction [from 36.2 fills per 100-person years in 2010 to 9.2 in 2024]), respectively. The proportion of all opioid fills written by primary care clinicians decreased (eg, Medicare Advantage with disability cohort: from 52.2% to 47.2%), whereas those written by pain medicine specialists increased (eg, Medicare Advantage with disability cohort: from 17.1% to 25.7%). Distinct trends for short-term and long-term opioid use episodes were observed in prescription characteristics, such as daily dose and duration. Conclusions and Relevance In this cross-sectional study of opioid prescribing trends in the US between 2010 and 2024, decreases in prescribing were greatest in long-term opioid use episodes, and prescribing was increasingly concentrated among pain medicine specialists. These findings suggest the need to balance reductions in opioid prescribing with provision of nonopioid pain treatments and raise concerns about access to care for patients taking opioids for chronic pain management.

Importance High-quality evidence guiding opioid prescribing decisions for acute pain across common diagnoses is lacking. Objective To describe pain trajectories and patterns of opioid and nonopioid treatment use among individuals who were offered opioids for the treatment of acute pain. Design, Setting, and Participants This was a prospective cohort study of patients recruited from 5 US health systems between September 2020 and March 2023 in emergency departments (EDs), primary care clinics, dental practices, or after cesarean delivery or knee replacement. Eligible patients were opioid-naive adults aged 18 years or older at all study sites, as well as adolescents aged 15 to17 years undergoing impacted molar extraction at 1 site, who were offered an opioid prescription for acute pain. Analysis was conducted April 2023 through February 2026. Exposure Offer of a prescription for an opioid analgesic. Main Outcomes and Measures Time to pain resolution (3 consecutive reports of no pain), patterns of opioid and nonopioid treatment use, and opioid-related adverse effects, ascertained from digital questionnaires. Results Among 1708 enrolled patients (median age, 38 years [IQR, 28-52 years]; 615 [36.0%] reporting race or ethnicity underrepresented in studies of acute pain management) followed up for 180 days, 915 (53.6%) were recruited in EDs, 307 (18.0%) in primary or urgent care, 263 (15.4%) in dental settings, and 223 (13.1%) in inpatient settings. Pain sources included dental (302 patients [17.7%]), trauma or injury (302 [17.7%]), obstetric (176 [10.3%]), musculoskeletal (131 [7.7%]), and low back (100 [5.9%]). Among 1502 patients reporting pain level at least once, median time to pain resolution irrespective of the treatment approach was 20 days (IQR, 8-88 days), with longer durations for surgical pain (74 days [IQR, 30 days to not reached]) and low back pain (69 days [IQR, 18 days to not reached]). The median time to opioid discontinuation among 1189 patients (69.6%) who reported any opioid use was 7 days (IQR, 2-31 days); an estimated 10.0% (95% CI, 7.7%-12.7%) of patients used opioids for at least 90 days, with higher rates in people reporting frequent pain before enrollment. Of 1482 patients (86.8%) completing at least 1 survey during the first 2 weeks of follow-up, 1153 (77.8%) reported using any opioids and 1287 (86.8%) reported using acetaminophen or ibuprofen. Among 619 (52.1%) patients with any opioid use who reported the dose of opioids taken in the first 15 days, daily doses were low (median, 10 [IQR, 5-15] morphine milligram equivalents). Most respondents reported leftover opioids (657 of 982 responding [66.9%]). Conclusions and Relevance In this cohort study of opioid-naive patients with acute pain, opioid use was generally low dose and of short duration, although some patients reported prolonged opioid use; most reported achieving pain resolution within 3 weeks, with longer times for surgical and low back pain. The findings suggest current guidelines for multimodal treatment and for short-duration opioid prescriptions if needed will serve many but not all patients, and treatment should be tailored to address individual patients’ needs.

Black race and Hispanic ethnicity are associated with higher mortality in severe combined immunodeficiency (SCID) following hematopoietic cell transplantation (HCT), though mechanisms remain unclear. We evaluated 796 children with SCID who received nonsibling HCT between 1982 and 2020 using data from the Primary Immune Deficiency Treatment Consortium. Overall survival for Black (aHR 2.47, 95%CI 1.64, 3.71) and Asian/Pacific Islander patients (aHR 1.82, 95%CI 1.00, 3.30) was significantly lower compared with non-Hispanic White patients, while Hispanic patients had lower event-free survival (aHR 1.83, 95%CI 1.27, 2.63) compared with non-Hispanic White patients. Even after adjusting for age and infection, Black patients with SCID had more than twofold hazard of death compared with non-Hispanic White patients. NBS was associated with earlier diagnosis, reduced infection at HCT, and elimination of survival disparities between Black and non-Hispanic White patients. These findings suggest that universal, system-level interventions such as NBS can mitigate disparities in outcomes for children with SCID.

Background/Purpose Although intravenous (IV) regular insulin has been the main treatment option for management of acute hyperkalemia, our institution utilizes IV insulin lispro as the preferred rapid-acting insulin. Little data currently exists on the safety or efficacy of insulin lispro for this indication. This study aims to evaluate the safety and efficacy of this alternative. Methods This study is a retrospective chart review of adult patients who received IV insulin lispro in an academic medical center Emergency Department (ED) for the treatment of hyperkalemia. The main efficacy and safety outcomes evaluated within 6 hours post-insulin administration were: change in serum potassium concentration and the incidence of hypoglycemia. Results One hundred and thirteen IV insulin lispro administrations were included. For evaluation of efficacy, the mean serum potassium before insulin administration was 6.6 mmol/L. The mean first serum potassium concentration after insulin administration was 5.5 mmol/L, with a serum potassium decrease of 1.1 mmol/L. As for safety, the mean blood glucose before insulin administration was 147.8 mg/dL. The mean first blood glucose after insulin administration was 149.9 mg/dL. Dextrose was co-administered 90.2% of the time. There were a total of 18 hypoglycemic events (15.9%), including 3 events that met the criteria for severe hypoglycemia (2.7%). Conclusion For treatment of hyperkalemia in ED patients, IV insulin lispro appears to be an efficacious alternative to IV insulin regular. However, a further review of its safety profile is warranted.

Background Evidence to guide the optimal timing of antiplatelet and oral anticoagulants (OACs) therapy after hemorrhagic infarction (HI) versus parenchymal hematoma (PH) is limited and inconsistent, leading to substantial variation in practice. This study's goal was to study the practice pattern and compare clinical outcomes associated with early‐versus‐delayed initiation of antiplatelet/OACs after hemorrhagic transformation (HT). Methods This multicenter, retrospective, cross‐sectional study included patients with acute ischemic stroke and HT. Patients with an HI or PH were categorized by HT to antithrombotic initiation time, and their outcomes—30‐day HT exacerbation, composite outcomes of recurrent stroke/systemic emboli, 90‐day vascular death, and functional outcomes—were compared. Results Of 748 patients, 496 received antiplatelets, and 252 received OACs after HT. The median HT‐to‐antiplatelet time was significantly shorter after HI than PH (1 [interquartile range, 0–2] versus 3 [interquartile range, 1–5] days; P <0.001). There were no statistically significant differences in HT exacerbation and composite outcomes (30‐day), as well as vascular death and unfavorable functional outcomes (90‐day), between patients who received same‐day, early (HI, <1 day; PH, <3 days), or late (HI, >1 day; PH, >3 days) antiplatelets after either HI or PH. Among patients on OACs, those with HI had shorter median HT‐to‐OAC time than PH (7 [interquartile range, 2–15] versus 15 [interquartile range, 7–32] days; P <0.001). Although HT exacerbation rates (30‐day) were comparable between early (HI, <7 days; PH, <15 days) and late (HI, >7 days; PH, >15 days) OAC initiation after either HI or PH, late initiation after PH was accompanied by higher rates of composite outcomes (30‐day) than early initiation (20.7% versus 3%; P =0.044). Regression models adjusted for demographics, National Institutes of Health Stroke Scale, and stroke severity showed no statistically significant association between early initiation of antiplatelets or OACs with HT exacerbation risk. Conclusions Our study found no statistically significant difference in HT exacerbation between early and late initiation of antiplatelets or OACs among patients with HI/PH, while prolonged delay among patients with PH were accompanied by increased systemic thromboembolic events. Although these findings offer preliminary clinical insight, prospective studies are needed.
