Abstract Clinical narrative text contains crucial patient information, yet reliable extraction remains challenging due to linguistic variability, documentation habits, and differences across care settings. Large language models (LLMs) have shown strong accuracy on clinical information extraction (IE), but their reproducibility (stability under repeated runs) and robustness (stability under small, natural prompt variations) are less consistently quantified, despite being central to clinical deployment. In this study, we evaluate three open-weight LLMs representing distinct modeling choices: a dense general-purpose model (Llama 3.3), a mixture-of-experts (MoE) general-purpose model (Llama 4), and a domain-tuned medical model (MedGemma). We focus on binary clinical IE aligned with four mobility classes from the International Classification of Functioning, Disability and Health (ICF) framework. Using a controlled experimental design, we quantify (1) intra-prompt reproducibility across repeated sampling and (2) inter-prompt robustness across paraphrased prompts. We jointly report predictive performance (F1-score) and stability (Fleiss’ Kappa). And we test factor effects using three-way ANOVA with post-hoc comparisons. Results show that increasing temperature generally degrades agreement, but the magnitude depends on model and task; furthermore, prompt paraphrasing can substantially reduce stability, with particularly large drops for the MoE model. Finally, we evaluate a practical mitigation, self-consistency via majority voting, which improves κ substantially and often improves or preserves F1-score, at the cost of additional inference. Together, these findings provide a reproducible framework and concrete recommendations for evaluating and improving LLM reliability in clinical IE.

Abstract Introduction The evaluation of diastolic function in diabesity patients undergoing incretin-based therapy could facilitate early detection and help prevent progression to heart failure. Methodology A group of 15 diabesity cases with chest x-ray examinations (< 1 month) before and after ≥ 12 months of incretin-based therapy (absent ventricular/valvular dysfunction) were identified. Standard diabesity descriptors and predictions of pulmonary venous hypertension (aka “pulmonary congestion”) [None; Stage 1: vascular distention/redistribution but minimal interstitial edema; or Stage ≥ 2: vascular congestion with ≥ mild interstitial or alveolar edema] by validated AI-enabled chest x-ray staging, representing mean left atrial pressure in diastolic dysfunction, were evaluated pre- and post-therapy. Results By weight loss, cases clustered into equal-sized subgroups: 1. Significant Responders (9–30% decreases); 2. Insignificant Responders (0–2% decreases); and 3. Non-Responders (2–12% increases). Regarding hemoglobin A1c changes: 1. Significant Responders collectively decreased; 2. Insignificant Responders varied; and 3. Non-Responders were largely stable. Pre-therapy, all 15 cases demonstrated AI-enabled chest x-ray evidence of diastolic dysfunction; post-therapy, 4 improved (especially cases of greatest weight loss or hemoglobin A1c reduction), 5 were stable, and 6 worsened. Per subgroup, AI-enabled chest x-ray indications therapeutic response were: 1. Significant Responders (all demonstrating unequivocally decreased obesity and improved diabetes) collectively showed stable-decreased dysfunction; 2. Insignificant Responders (all demonstrating minimally decreased obesity but stable-worsening diabetes in most) reflected stable-increased dysfunction in 60%; and 3. Non-Responders (all demonstrating increased obesity but stable-improved diabetes) showed increased dysfunction in 80%. Conclusion AI-enabled CXR staging detects background subclinical diastolic dysfunction in diabesity and monitors its response to incretin-based therapy.

Critically ill patients frequently require intrahospital transport (IHT) to diagnostic exams or procedures and must remain connected to life-sustaining medical lines. During IHT, the risk of tangled medical lines is unavoidable. The idea for a novel medical line securement device was inspired by a patient transport nurse due to frustrations and workflow inefficiencies managing tangled medical lines. The study aim was to explore the correlation between the utilization of a single-use securement device to manual or accidental disconnections of medical lines during IHT, and nurses’ perception of efficiency, compared to the current practice of no utilization of a securement device. In 2019, a randomized, descriptive, correlational study was conducted on 142 progressive and intensive care hospitalized patients. Study coordinators measured the number of times either IV lines or monitor cords were accidentally or manually disconnected to detangle during or after transportation and the perception of transport efficiency. Results revealed fewer manual disconnections among intervention group compared to the control. Nurses’ perception regarding the efficiency between the intervention and control group was statistically significant when the device was utilized to secure the lines and cords during transport. Nurses reported much higher satisfaction rates of transport efficiency when the device was used. This finding showed the device’s utility for improving nurse satisfaction during IHT of critically ill patients. Utilization of the medical line securement device may be generalizable across other healthcare settings and disciplines where the complexity of medical lines may exist.

Summary Background Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal lung disease characterized by aberrantly activated, apoptosis-resistant profibrotic lung (myo)fibroblasts. Prior research has demonstrated that lung fibroblasts from patients with IPF exhibit resistance to DNA damage, suggesting that this behavior contributes to their persistent survival and continuous proliferation. We propose that elevated levels of the DNA damage repair protein RAD51 regulate myofibroblast activation and apoptosis and provide a potential therapeutic target to impede fibrosis progression. Methods Human lung fibroblasts were transfected with siRNA against RAD51 or treated with RAD51-specific inhibitor B02 and markers of fibrosis, DNA damage, apoptosis, metabolic reprogramming, and mitochondrial dynamics were assessed. The preclinical efficacy of B02 was evaluated in human precision cut lung slices (PCLS) and in a mouse model of pulmonary fibrosis. Findings RAD51 expression was significantly upregulated in the lungs and lung fibroblasts of IPF patients. Knockdown or inhibition of RAD51 in fibroblasts reduced profibrotic marker expression, suppressed mTORC1 signaling and mitochondrial function, and increased apoptosis susceptibility. Pharmacological inhibition of RAD51 shifted the profibrotic phenotype towards a fibrosis-resolving state in human and mouse PCLS, and in a bleomycin-induced mouse model of lung fibrosis. Interpretation The inhibition of RAD51 exerts therapeutic benefits in lung fibrosis by promoting apoptosis. Our findings identify that inhibiting RAD51 with B02 in fibroblasts impairs DNA repair and induces metabolic reprogramming, making it a potential therapeutic target. Research in context Evidence before this study Pulmonary fibrosis (PF) is characterized by excessive fibroblast activation and subsequent deposition of extracellular matrix (ECM) proteins, which ultimately disrupt normal lung architecture. A significant contributing factor to the pathogenesis of pulmonary fibrosis is the presence of fibroblasts that are resistant to apoptosis, preventing normal wound healing. Recent studies highlight the DNA repair protein RAD51 as effective in protecting fibroblasts from death induced by chemotherapy and ionizing radiation. These finding suggested that RAD51 could have a role in fibroblast activation and apoptosis resistance in pulmonary fibrosis. Added value of this study We demonstrated that RAD51 is important for maintaining apoptosis-resistant fibrotic fibroblasts and their metabolic abnormalities. Our findings indicated that TGFβ-mediated upregulation of RAD51 reduces DNA damage, activates multiple pathways related to fibroblast activation and proliferation, and induces metabolic reprogramming, ultimately regulating apoptosis. Mechanistically, RAD51 inhibition enhanced p53 acetylation at lysine 120 and upregulated the expression proapoptotic proteins PUMA/BAK in mitochondria, promoting apoptosis. Pharmacological inhibition of RAD51 using the specific inhibitor B02 during the fibrotic phase of experimental lung disease effectively ameliorated pulmonary fibrosis. Implications of all the available evidence Our findings establish that RAD51 plays an important role in the survival of apoptosis-resistant fibrotic fibroblasts. We propose that reducing RAD51 expression leads to the metabolic reprogramming of activated fibroblasts, resulting in decreased mitochondrial respiration, reduced ATP levels, and diminished glycolysis or glutaminolysis. These observations suggest that targeting energy metabolism through RAD51 inhibition could be a viable strategy to enhance apoptosis, thereby creating a therapeutically targetable pathway in fibrotic cells. These findings highlight the potential of RAD51 as a therapeutic target for the treatment of IPF.

Objective To evaluate cancer risk in individuals with cleft lip and/or cleft palate (CL/P). Design Retrospective chart review of patients with CL/P, including abstraction of information on cancer diagnoses was conducted. Cancer risk was compared with national population-based estimates using standardized incidence ratios (SIRs) and exact binomial tests. Subgroup analyses compared demographic and clinical characteristics between patients with and without cancer. Setting Study was performed at a single tertiary academic center with multidisciplinary surgical, pediatric, and genetic care. Patients/Participants Total of 2121 patients with CL/P from 1970 to 2024 with complete medical documentation were included. Main Outcome Measures Main outcomes included prevalence of cancer diagnoses, childhood cancer incidence, and differences in cancer occurrence by age, cleft type, syndromic status, and family history. Results Total of 144 patients (6.8%) had pathologically confirmed cancer diagnoses. Twelve childhood cancers were identified, with 10 cases presenting before age 15. Children younger than 15 with CL/P had a significantly elevated cancer risk (SIR 4.7; 95% confidence interval: 1.8-7.6; P < .00001). Pediatric cancers occurred mainly in syndromic cases. Cancer prevalence was higher in cleft palate only and cleft lip/palate cases compared with cleft lip only ( P < .05). Cancer occurrence was not higher in adults with CL/P compared to the general population. Conclusions Cancer risk is not uniformly elevated over the lifespan in individuals with CL/P. Increased cancer risk is observed in our pediatric cohort. Clinical care should include careful assessment of childhood cancers, syndromic features, and family history, with consideration for genetic counseling and multidisciplinary follow-up.

Background: Chronic hip abductor insufficiency remains a challenging problem to treat and can result in significant disability in some patients. Tendon transfers involving the gluteus maximus (GM) or combined GM with tensor fascia latae (GM+TFL) are common options for surgical reconstruction. The purpose of this systematic review was to compare clinical outcomes, complications, and revisions rates of patients who underwent GM transfer or GM+TFL transfer for irreparable hip abductor tears. Methods: PubMed (MEDLINE), Scopus (EMBASE, MEDLINE, COMPENDEX), and Cochrane databases were used to conduct a systematic review of articles from inception to February 2025. A total of 18 studies were included (11 GM transfer, 7 GM+TFL transfer). Demographics, hip setting (native hip, primary total hip arthroplasty [THA], revision THA), patient-reported outcome measures, presence of Trendelenburg gait, abduction strength, complication rates, and revision rates were analysed. Results: A total of 207 patients (208 hips) underwent GM transfer, while 55 patients (55 hips) underwent GM+TFL transfer. Meta-analyses demonstrated that both techniques yielded significant preoperative to postoperative improvements in modified Harris Hip Scores/Harris Hip Scores and Visual Analogue Scale pain scores ( p < 0.001). In total, 33.9% of patients who underwent GM transfer had a persistent Trendelenburg gait postoperatively, compared to 48.1% of those who underwent GM+TFL transfer. The complication rate was 16.8% (23/137) for patients who underwent GM transfer and 2.7% (1/37) for those who underwent GM+TFL transfer; while revision rates were 5.9% (9/152) and 3.6% (2/55), respectively. Conclusions: Both GM and GM+TFL transfers yielded comparable outcomes in patients with chronic hip abductor insufficiency not amendable to primary repair. The complication rate was substantially higher in patients who underwent GM transfer, whereas revision rates were comparably low for both techniques. In particular, a sizeable proportion of patients continued to exhibit a persistent Trendelenburg gait postoperatively following both surgical techniques, highlighting the complexity of this pathology.

Vaccine hesitancy refers to the delay in accepting or refusing vaccines despite the availability of vaccination services. Well-conducted studies and trials reviewed in this article support methods both to prevent and manage vaccine hesitancy. Clinicians should know which vaccines their patients are due to receive and should use every encounter to address this issue. Research shows clinicians' recommendations increase vaccine uptake. Recommendations that patients perceive as stronger have a greater effect in increasing vaccine uptake. Using presumptive language to phrase the recommendation is more effective than presenting the vaccine conversationally as an option for the patient. When the patient counters the strong recommendation with hesitancy, the clinician should engage the patient with motivational interviewing, perhaps using a four-step process called the "Four A's".
