Abstract Background Obstructive sleep apnea (OSA) is a risk factor for hypertension and some evidence suggests this risk may not be mitigated with positive airway pressure. Low-intensity statin therapy can modestly reduce blood pressure (BP). In this exploratory analysis, we examined if six months of high-intensity statin therapy could lower resting or ambulatory BP in patients with OSA. Methods 39 patients with OSA (13F, age = 49 ± 9yrs, body mass index = 32.9 ± 4.2kg/m2, apnea-hypopnea index = 22.2 ± 12.4 events/hour) were randomized to high-intensity atorvastatin or placebo. BP was assessed using seated, “office” measurements and in 20-minute intervals over 24 consecutive hours at three timepoints (baseline, three- and six-months post-randomization). Participants maintained a diary denoting sleep and wake times for analysis. Changes (Δ) in BP from baseline were assessed and adjusted for adherence to participants’ intervention (atorvastatin or placebo) as well as to their treatment for OSA (yes or no). Results There were no between-group differences in baseline BP variables (P = .09-.96). At three months, the changes in resting (P = .74-.87), 24 hour mean (P = .54-.96), daytime (P = .70-.96), nor nighttime (P = .74-.96) BP did not differ between groups. Similarly, the changes in resting (P = .23-.92), 24 hour mean (P = .51-.82), daytime (P = .17-.78), and nighttime (P = .51-1.00) BP did not differ between groups following six months of their respective intervention. Conclusions Our data suggest that high-intensity atorvastatin does not lower resting or ambulatory BP in patients with OSA relative to a placebo. Thus, it does not appear that atorvastatin is a viable adjunct intervention for BP reduction in patients with OSA. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT03308578.

Background: Coronary artery disease (CAD) is common among liver transplantation (LT) candidates, yet whether pre-transplant percutaneous coronary intervention (PCI) improves post-LT outcomes remains uncertain. Methods: We conducted a single-center, Institutional Review Board-approved cohort study of adults undergoing LT from 2005 to 2025. Asymptomatic candidates with significant stenosis on invasive angiography were included; prior coronary artery bypass grafting was excluded. The primary endpoint was major adverse cardiovascular events (MACE: myocardial infarction [MI], stroke/transient ischemic attack, new systolic dysfunction, post-LT coronary revascularization, or all-cause death). Results: Among 111 patients (median age 65 years; 84% male), 66 (59%) underwent PCI and 45 (41%) were managed medically. Over a median 32 months of follow-up, 61 patients (55%) experienced MACE. Composite MACE did not differ between PCI and non-PCI groups (52% vs. 60%, p = 0.40; log-rank p = 0.59). Fine–Gray modeling showed no association of PCI with MACE; independent predictors were prior MI (HR 1.81, 95% CI 1.01–3.24) and pre-transplant dialysis (HR 2.13, 95% CI 1.07–4.24). Major bleeding occurred in 7%. Matched and era-stratified analyses were concordant. Conclusions: In asymptomatic LT candidates with angiographically severe CAD, pre-LT PCI was not associated with a lower incidence of post-LT MACE.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is rapidly emerging as the leading cause of chronic liver disease, closely tied to rising global obesity rates. Endoscopic bariatric therapies (EBTs), including endoscopic sleeve gastroplasty (ESG), intragastric balloons (IGB), duodenal-jejunal bypass liners (DJBL), and duodenal mucosal resurfacing (DMR), offer minimally invasive interventions that target metabolic dysfunction and weight loss. This review synthesizes current evidence on the mechanisms and hepatic outcomes of EBTs in MASLD, highlighting improvements in hepatic steatosis, liver stiffness, and fibrosis biomarkers across multiple modalities. ESG is consistently associated with reductions in hepatic steatosis and fibrosis scores across multiple studies. IGB therapy improves liver stiffness and reduces hepatic fat as assessed by imaging modalities such as MRI- Proton Density Fat Fraction and ultrasound. DJBL lowers liver enzymes and improves non-invasive markers of steatohepatitis like the Fibroscan-AST score, although its effect on fibrosis appears limited. DMR demonstrates reductions in liver fat, particularly in patients with type 2 diabetes, but evidence for histological improvement in MASLD remains inconsistent. Despite their promise, most EBT studies remain limited by small sample sizes and short follow-up. Further randomized trials are needed to validate long-term efficacy and position EBTs alongside or as alternatives to surgical interventions for MASLD.

Abstract In recent years, various tracking technologies that work independently of imaging systems have been proposed to automate, simplify, and enhance various tasks in the brachytherapy treatment workflow. These tasks, critical to the overall accuracy of the therapeutic dose delivery, include applicator, catheter and needle insertion guidance, and reconstruction as well as transfer tube connection in afterloading technique. Task Group 317 was established as a joint American Association of Physicists in Medicine (AAPM) and European Society for Radiotherapy and Oncology (ESTRO) committee to review: the current state‐of‐the‐art scientific literature as it pertains to tracking technology in the field of brachytherapy; the benefits and issues related to the use of the technology for automated reconstruction of brachytherapy implants, quality control (QC) tasks such as channel path and tip reconstruction, and real‐time guidance tasks; their limitations, in particular in the clinical environment and, finally, to develop recommendations related to commissioning, quality assurance (QA) and clinical use. The Task Group has looked in detail at key tracking technologies in advanced brachytherapy applications: infrared, electromagnetic, fiber optic shape sensing (fiber Bragg grating), and active radiofrequency coil tracking. For each, the performance and accuracy in well‐controlled conditions as well as in clinically relevant environments are provided. Guidelines for clinical implementations, including target accuracy and performance needed for critical tasks, are summarized. Risk‐based analysis is discussed in the context of an electromagnetic‐based tracking system used as part of a clinical trial. The report concludes with the essential elements of an effective quality management program dedicated to the advanced features enabled by the above‐described technology.

BACKGROUND Glossopharyngeal neuralgia (GPN) is a rare disorder characterized by severe, episodic pain along the sensory distribution of cranial nerve (CN) IX. Bilateral GPN presents unique challenges for consideration of microsurgical treatment due to potential risks of postoperative dysphagia and cardiac arrhythmias associated with resection of bilateral CN IX/X. Here, the authors describe successful staged bilateral microsurgical rhizotomy of CN IX and upper CN X rootlets to treat bilateral GPN. OBSERVATIONS A 54-year-old female presented with right GPN and underwent a right retrosigmoid craniotomy with rhizotomy, resulting in complete resolution of pain. During the following year, the patient developed left GPN and was considered for the same surgical intervention. However, prior to pursuing surgical intervention, evaluation of her swallowing function was conducted to stratify her risk of pharyngeal sensory denervation or dysphagia, and to confirm her suitability for left-sided rhizotomy. Given the patient’s normal oropharyngeal swallowing function on videofluoroscopic swallow study, she underwent left retrosigmoid craniotomy with rhizotomy. At the 3-month follow-up, the patient described complete resolution of pain and normal swallowing function. LESSONS With the use of comprehensive patient evaluation between surgical stages, staged bilateral microsurgical rhizotomy is a feasible and safe treatment option for carefully selected patients with bilateral GPN. https://thejns.org/doi/10.3171/CASE25359

Abstract Chimeric antigen receptor (CAR) T-cell (CAR-T) treatment for B-cell acute lymphoblastic leukemia (ALL) induces high initial response rates, but most patients relapse. Low disease burden (often defined as <5% blasts in the bone marrow) is associated with better outcomes. CAR HEMATOTOX (HT) is a score using prelymphodepletion hematologic and inflammatory parameters to predict outcomes in lymphoma. Here, we assess its prognostic utility in a large multicenter adult B-cell ALL cohort. Patients who received brexucabtagene autoleucel across 33 centers in North America were included as part of the Real-World Outcomes Collaborative of CAR-T in Adult ALL (ROCCA) consortium. An independent cohort of 61 patients with ALL treated with an investigational CD19 CAR-T therapy at 1 center was also described. Among 199 ROCCA consortium patients, 43 (22%) patients with HTlow scores had lower rates of delayed neutrophil recovery than those with HThigh scores (26% vs 52%, P = .002) and fewer severe infections (2.5% vs 18.8%, P = .011). They also had higher response rates, overall survival (OS), and event-free survival (EFS), as well as lower nonrelapse mortality and cumulative incidence of relapse. The survival differences remained significant after multivariable adjustment for disease burden and other covariates. In the investigational cohort of 61 patients, patients with HTlow scores had improved OS and EFS, as well as higher peak CAR-T expansion. In summary, CAR HT score is a prognostic factor independent of disease burden in adult ALL. HTlow score is associated with superior outcomes after CD19 CAR-Ts and higher CAR-T expansion in a single-center cohort. These trials were registered at www.clinicaltrials.gov as #NCT01044069 and #NCT01860937.

Background and Aims: Primary biliary cholangitis is a chronic cholestatic liver disease that may progress to cirrhosis and liver failure. For patients with inadequate response or intolerance to ursodeoxycholic acid, peroxisome proliferator–activated receptor (PPAR) agonists have emerged as second-line options. This study assessed the comparative effectiveness and safety of PPAR agonists in primary biliary cholangitis through a systematic review and network meta-analysis. Approach and Results: A systematic review identified randomized controlled trials evaluating PPAR agonists versus ursodeoxycholic acid, with or without placebo. A frequentist network meta-analysis assessed biochemical response (primary outcome) and ALP normalization (secondary outcome). Pairwise meta-analyses were performed for percentage change in ALP and total bilirubin, and adverse events leading to treatment discontinuation. Data were stratified by baseline ALP, and a random-effects model was used. Eight randomized controlled trials (727 participants) evaluating 4 PPAR agonists were included. All agents outperformed placebo in achieving biochemical response and ALP normalization. Bezafibrate ranked highest for the primary outcome; both bezafibrate and seladelpar ranked highest for the secondary outcome. Percentage ALP reduction did not vary by baseline ALP. Total bilirubin changes were similar across arms, and treatment discontinuations due to adverse events were infrequent. Conclusions: PPAR agonists are effective second-line therapies for primary biliary cholangitis. Treatment ranking differences likely reflect variations in outcomes, populations, and drug mechanisms. In the absence of head-to-head trials, network meta-analysis provides important insights into comparative effectiveness. Further studies are warranted to confirm long-term safety and improve the evaluation of patient-centered outcomes.
