Objectives Female sex and anticitrullinated protein antibodies (ACPA) are associated with higher disease activity in rheumatoid arthritis (RA). Since disease-related inflammation is linked to cardiovascular risk, we explored whether sex and ACPA influenced the association between disease activity at study entry and cardiovascular risk in established RA. Methods We evaluated 4008 patients with prevalent RA from an international observational cohort enrolled between 1985 and 2012. Outcomes included major adverse cardiovascular events (MACE: cardiovascular death, myocardial infarction and stroke) and ischaemic cardiovascular events (iCVE: MACE, angina, revascularisation, transient ischaemic attack and peripheral arterial disease). Follow-up accrued from enrolment until the first event or censoring. Multivariable Cox models stratified by centre risk evaluated disease activity, sex, ACPA and their interactions. Results We documented 193 MACE and 299 iCVE. Disease activity and sex were associated with MACE (all p≤0.017) and iCVE (p≤0.005) but ACPA was only associated with MACE (p=0.043). A three-way interaction on MACE (p=0.034) but not iCVE was noted. Among ACPA-negative patients, disease activity was associated with MACE in males (HR 1.57 (95% CI 1.14 to 2.16)) but not females (p-for-interaction=0.022). Among ACPA-positive patients, neither the disease activity x sex interaction (p=0.929), nor main effect of disease activity on MACE (p=0.124) was significant, but male sex was (HR 1.61 (95% CI 1.15 to 2.27)). Among females, neither disease activity x ACPA interaction (p=0.523) nor disease activity (p=0.319) was significant for MACE, but ACPA was (HR 1.57 (95% CI 1.02 to 2.42)). Conclusions The effect of disease activity at enrolment on cardiovascular risk in prevalent RA varies across patient groups with different sex and ACPA characteristics.

OBJECTIVES: The overall goal of this work is to discuss the various topics associated with critical care advanced practice provider (APP) postgraduate training programs and provide resources for new, developing and existing programs. DESIGN: Three rounds of voting until consensus achieved. SETTING: Electronic surveys, followed by virtual meeting. SUBJECTS: Critical care APPs, physicians, a pharmacist, and a nurse were also included to ensure multidisciplinary representation. All subjects resided and practiced in the United States with a history of education scholarship or post-graduate training leadership. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The workgroup included 14 APPs (ten nurse practitioners and four physician associates), three physicians, one pharmacist, and one registered nurse from 14 institutions across the United States. The workgroup identified six areas of concentration: administration, audience, program structure, curriculum, procedural competence, and accreditation. A survey was generated and employed in three rounds. The first two rounds of voting were completed anonymously, the third round was completed as a live meeting until consensus recommendations, defined as 75% agreement or more, were achieved. CONCLUSIONS: Expert consensus was used to generate consensus recommendations for critical care postgraduate training programs based upon 3 rounds of voting.

Abstract Aims Acute myocardial infarction (AMI) patients face a substantial risk of cardiovascular events and rehospitalization. The impact of the SmartHeart 12-lead electrocardiogram (ECG) telemedicine device on healthcare utilization has not been tested in a US randomized trial. Methods and results Patients with AMI were randomized at discharge to standard of care without (control group) or with the SmartHeart 12-lead ECG device (intervention group). The primary endpoint was the rate of emergency department (ED) visits, hospital readmissions, and any cardiovascular testing from discharge to 90 days of follow-up. The primary endpoint was reached in 57 (59%) patients in the control group and 53 (63%) patients in the intervention group (P = 0.61). However, in the intervention group, only 30% of patients complied with two follow-up training SmartHeart 12-lead ECG transmissions after discharge, and only 24% used the device thereafter. Among device users, ED presentations were lower in the intervention group than in the control group (8.0% vs. 29%, P = 0.04). In all patients advised to present to the ED upon device use (38%), a clinically relevant cardiovascular diagnosis was made. One patient survived a ventricular fibrillation cardiac arrest as advised to present to ED urgently after device use. Conclusion In this US-based RCT, there were no significant differences in the primary outcome in the intention-to-treat analysis. However, according to per-protocol analysis, proper use of the SmartHeart ECG device with 24/7 telemedicine support reduced inappropriate and increased appropriate ED presentations after hospitalization for AMI.

Abstract The kinesin-5 motor protein KIF11 is crucial for mitotic spindle assembly, driving the separation of spindle poles through microtubule sliding. Src-family kinases phosphorylate KIF11 at multiple tyrosine residues within its motor domain, but the mechanistic consequences of these modifications remain unclear. Here, we dissect the role of phosphorylation at Y211 using phospho-mimetic (Y211E) and non-phosphorylatable mutants (Y211F) in biochemical, biophysical, and cellular assays. Optical trapping and Förster resonance energy transfer (FRET) analyses reveal that Y211 phosphorylation slows neck-linker docking, reducing motor velocity and force generation under load. In human cells, Y211E expression impairs bipolar spindle formation and decreases spindle pole separation velocity, while Y211F shortens steady-state spindle length. Fluorescence recovery after photobleaching (FRAP) analyses show that Y211E accelerates motor turnover on spindle microtubules, consistent with the mutant motor’s heightened load sensitivity. Together, these findings support a model in which Src-mediated phosphorylation at Y211 acts as a rheostat to tune KIF11 mechanochemistry and spindle assembly dynamics, linking cancer-relevant kinase signaling to mitotic force generation.

What was done? A review of artificial intelligence (AI) applications for the imaging of uterine fibroids, endometriosis, and adenomyosis. What was found? AI models can assist with the recognition, segmentation, and localization of uterine fibroids, and the differentiation of benign fibroids and sarcomas. Models can aid in the diagnosis of adenomyosis and endometriosis, and the prediction of the impact of endometriosis on fertility. What the findings mean? Deployed thoughtfully, AI tools could reduce variability, shorten read times, and add objective measurements to routine care. Studies evaluating these models are limited by single-institution designs and continued reliance on expert sonologists and radiologists.

Background: Running often elicits stress urinary incontinence (SUI) in parous athletes. While cadence retraining improves running biomechanics, its impact on incontinence is unclear. This feasibility study assessed the implementation and preliminary effects of a 6-week cadence retraining program in parous female runners with SUI. Methods: A total of 8 participants with self-reported SUI and a preferred running cadence ≤ 170 steps/minute underwent treadmill testing before and after the intervention. The program involved a 6-week cadence retraining program using a Garmin Forerunner 55 watch. Feasibility was assessed across 6 domains. Running outcome measures included cadence and vertical oscillation. SUI outcome measures included the Questionnaire for Urinary Incontinence Diagnosis and Urinary Distress Inventory-6 scores. Paired t-tests were conducted (α = .05). Results: Following the 6-week program, feasibility outcomes supported the viability of study procedures and high adherence. Statistically significant increases in cadence ( P = .016) and decreases in vertical oscillation ( P = .019) and concomitant decreases in Questionnaire for Urinary Incontinence Diagnosis ( P = .013) and Urinary Distress Inventory-6 ( P = .042) scores were observed. Discussion: This study demonstrated the feasibility and acceptability of a 6-week cadence retraining program for parous runners with SUI. Given the growing movement to foster athleticism after pregnancy, these findings will appeal to physical therapists searching for acceptable treatment options for SUI in parous runners. Preliminary running mechanics and SUI symptoms warrant a larger randomized controlled trial. A power analysis estimated a sample size of 66 participants for a future full-scale efficacy study.

Abstract Chimeric antigen receptor (CAR) T-cell therapy enriched for a memory-like phenotype may persist and function longer than a nonenriched product, thereby improving duration of response (DOR). We conducted a phase I study with bb21217 (NCT03274219), an anti–B-cell maturation antigen CAR T-cell therapy manufactured in the presence of the phosphoinositide 3-kinase inhibitor bb007 to enrich for T cells with a memory-like phenotype, in patients with relapsed/refractory multiple myeloma (N = 72). No new safety concerns were raised with bb21217 therapy (three cases each of grade ≥3 cytokine release syndrome and grade ≥3 neurotoxicity were observed). The objective response rate was 69.4% and the median DOR was 23.8 (95% confidence interval, 16.8–34.8) months. Analysis of the drug product established an association between early memory phenotype and robust expansion and depth of response. Examination of baseline characteristics indicated that tumor burden and prior therapies influenced DOR. The data indicate that generation of CAR T cells early in a disease course when tumor burden is lower and source material exhibits a more naïve phenotype may maximize the clinical benefit potential of the drug product.

With improvement in medical and surgical care, the number of adults with congenital heart disease (CHD) is soaring. Adults with CHD commonly have impairments in brain health. However, significant gaps in knowledge remain regarding the relevant types and prevalence of neurologic and psychiatric risk and their associated risk factors. We sought to review current evidence, identify gaps in knowledge, and develop key next steps to improve scientific understanding and clinical care. Three working groups—Genetics and Brain Health, Characterizing Neuropsychological and Psychological Outcomes, and Neuropsychological and Psychosocial Interventions—were composed of multidisciplinary experts in relevant clinical and research domains, as well as adults with CHD. Each group identified 5 key knowledge gaps and associated next investigations needed to address those gaps. For Genetics and Brain Health, 5 key knowledge gaps were identified: lack of a standardized neuroimaging protocol for adults with CHD, need to understand neuroradiological–pathological–neuropsychological correlates, role of gene–environment interactions, what can be learned from brain health risk models from other groups, and how existing multimodal approaches influence risk and neuroresilience. Adults with CHD can benefit from routine assessment of brain health, as well as increased clinical and basic research into the underlying factors that contribute to risk and neuroresilience for neurologic and psychiatric sequalae. Multidisciplinary collaborative efforts that incorporate adults with CHD across the research cycle are essential for all key next steps.

Objectives To comprehensively review the available literature on prehabilitation and rehabilitation exercise, nutrition, and psychological support interventions for patients with kidney cancer (KC), to summarise the clinically relevant efficacy and cost‐effectiveness of interventions, to expose key knowledge gaps, and to inform future investigations and initiatives. Methods This review was performed according to the per Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) Extension for Scoping Reviews Guidelines. We included randomised controlled trials (RCTs) assessing programmes of prehabilitation or rehabilitation, exercise, psychological support, or nutrition components in patients with KC or KC caregivers from January 2004 to March 2022. Statistically significant positive (SS+) and negative (SS−) results were summarised. Results The systematic search yielded 10 968 records including 18 RCTs, involving 2774 unique subjects, 706 of whom were KC patients/survivors. None included caregivers or assessed cost‐effectiveness. Two interventions were implemented before surgery, one was implemented prior to initiation of systemic therapy, eight were implemented during systemic or radiation therapy, three were implemented after treatment, while implementation time was not specified for four interventions. Conclusion Most (14/18) RCTs involving exercise, nutrition, psychological support, or prehabilitative or rehabilitative programmes for KC performed to date demonstrated SS+ results. The evidence was most robust regarding previously evaluated psychological support, especially mindfulness‐based interventions (9/10 studies demonstrating SS+ improvement in primary outcomes), followed by therapeutically valid exercise with/without psychological support (5/8 RCTs demonstrated efficacy), then nutrition or pharmacological interventions (2/5 demonstrated efficacy). Level 1 evidence supports counselling patients and referral to mindfulness‐based psychological therapy along with physical therapy or physical medicine and rehabilitation, as well as consideration of preoperative carbohydrate drinks. No studies have examined impact on caregivers, or cost‐effectiveness, which are both critical areas for future study.
