Background: Facial appearance influences social perception, with laypersons focusing on the central facial triangle; nasal differences may alter gaze patterns, but few studies have quantified this using eye-tracking. Objective: To evaluate how layperson gaze patterns shift in response to different nasal variations as measured by eye-tracking. Methods: In this prospective cohort study, facial images with 30 nasal differences were created using Photoshop to represent a range of phenotypes, such as dorsal hump, crooked nose, and pinched tip, alongside controls. Gaze data were captured via eye-tracking, and linear mixed-effects modeling assessed differences in time spent viewing defined areas of interest, adjusting for participant and image variables. Results: A total of 119 participants (53.8% female) were enrolled. The median age was 40 years, and 82% identified as Caucasian. Among the 30 nasal alterations, only the saddle nose resulted in significantly increased gaze time compared to controls (mean increase: 0.89 s; p < 0.001). Participant age, sex, and gender of the face in the image did not significantly influence gaze behavior. Conclusion: In this study, only the saddle nose attracted greater visual attention from lay observers compared with other nasal variants.

Background/Objectives: We performed a systematic review of preclinical literature on the use of high-LET particle therapy, DDRi, and/or immunotherapy specifically in pMMR colorectal cancer. Methods: A systematic review of the literature published between 2014 and 2025 was conducted across major databases. Studies were included if they examined particle radiotherapy (e.g., proton, alpha, and carbon) or X-ray radiation either alone or in combination with DDRi and/or immune checkpoint inhibitors (ICIs) in pMMR colorectal cancer models. Results: In total, 131 studies met the inclusion criteria, including 70 preclinical studies. These studies consistently demonstrate that high-LET radiation amplifies immunogenic cell death, increases cGAS-STING pathway activation, and enhances tumor antigen presentation, thereby fostering greater immune infiltration and systemic antitumor responses. Concurrent irradiation with DDRi enhances persistent DNA damage and cytosolic DNA accumulation. In murine models, high-LET therapies show excellent local control, with manageable toxicity profiles. Combination regimens with ICIs exhibit improved local control and elicit systemic antitumor immune responses. Conclusions: High-LET particle radiation and/or the use of concurrent DDRi with ICI have significant preclinical evidence of immunostimulatory effects in pMMR rectal adenocarcinoma and increased response rates to immunotherapy. The clinical evidence will be reviewed in the companion manuscript.

Background/Objectives: Hypofractionated ablative radiation is an increasingly popular option for patients with hepatocellular carcinoma (HCC). However, concern remains about the risk for radiation-induced liver toxicity in patients with decompensated liver function. Methods: We retrospectively identified patients with underlying Child-Pugh (CP) B or C liver function treated at our University and Veterans Affairs (VA) departments from 2014 to 2019. Primary endpoints included treatment-related toxicity and dosimetric parameters. Results: 38 patients were included in the analysis. Most patients (98%) had CP B or Albumin-Bilirubin (ALBI) grade 2–3 (100%) liver disease. The median dose was 50 Gy (range 30–50) delivered in 5 or 10 fractions. Most patients had a single tumor treated (66%) with a median size of 3.1 cm (Interquartile Range (IQR) 2.3–4.1). The mean liver dose was 9.28 Gy (IQR 6.76–13.64) with a liver D800cc of 3.99 Gy (IQR 1.41–8.02). All patients completed their intended course with a median follow-up of 43 months. Four patients (10.3%) developed non-classical radiation-induced liver disease (RILD), comparable to the rate for patients with CP A function treated contemporaneously (8.3%). Otherwise, one patient (2.6%) experienced acute grade 3+ (non-RILD) hepatobiliary toxicity, while one patient (2.6%) experienced late grade 3+ hepatobiliary toxicity. Local control was promising with 2-year freedom from progression in the treated lesion of 73% (95% CI 38–91%). Median overall survival was 12 months (95% CI 5–25 months). Conclusions: Ablative radiation for patients with decompensated liver function and HCC appears well tolerated with low rates of RILD and encouraging local control. With careful selection, these patients should be considered for inclusion in future randomized trials.

CD19-directed chimeric antigen receptor (CAR) T-cell therapies have been instrumental in improving outcomes of refractory or relapsed B-cell malignancies. However, there have been safety concerns due to recent reports of second primary malignancies (SPMs) related to CAR T-cell therapies. We reviewed articles from Embase, PubMed, and Cochrane Library records and included SPM case reports as well as cohort studies. Across published cohorts, secondary cutaneous or peripheral T-cell lymphoma (PTCL) after diffuse large B-cell lymphomas (DLBCLs) have been reported at low incidence (generally in the low single-digit percentage range). While CAR T-cell therapy is associated with these rare secondary malignancies and lineage-switch events primarily described in acute leukemia, they are clinically significant and have resulted in increased surveillance. The currently available evidence suggests that most secondary malignancies after CAR T-cell therapy are due to background risk and prior treatment exposures rather than direct CAR T-cell therapy induced oncogenesis. However, rare CAR T-cell therapy-associated second primary T-cell malignancies have been reported. To properly define incidence, mechanisms, and risk factors for CAR T-cell therapy-associated malignancies, continued prospective registry follow-up and additional research will be needed.

Intramedullary screw fixation (ISF) of metacarpal fractures is a well-established technique. Prior techniques either involve placement of the intramedullary screw in a retrograde fashion or placement of the guidewire in a retrograde fashion before placing the screw in an antegrade fashion. While effective, previously described techniques have risks of extensor tendon irritation, articular cartilage disruption, and limited access to multiple metacarpals from a single incision. We present a novel antegrade intramedullary screw placement and antegrade guidewire technique for ISF that avoids disruption of the metacarpal head and allows for access to multiple metacarpals through a single incision. Cadaveric evaluation confirmed consistent sparing of the distal carpal row and demonstrated the feasibility of this technique across the index through small finger metacarpals. Compared with previously described methods, this technique offers improved soft tissue preservation, reduced risk of tendon scarring, and enhanced surgical efficiency. Level of Evidence: Level IV—case report; cadaveric study.

Abstract Objective To assess the role of small‐molecule calcitonin gene–related peptide receptor antagonists (gepants) in the acute treatment of migraine, particularly in relation to triptan treatments. Background Triptans have established efficacy and are widely prescribed for the acute treatment of migraine. However, triptans may not be recommended for some individuals due to cardiovascular contraindications and precautions, as well as other comorbidities, and many may discontinue triptans because of inadequate or inconsistent symptom relief or poor tolerability. Several gepants are also indicated for the treatment of migraine (both acute and preventive), and their demonstrated efficacy and safety may address some challenges associated with triptans. Methods This narrative review addresses considerations for the acute treatment of migraine through summarizing literature and data from preclinical studies and clinical trials of triptans and gepants. Results We consider triptans and gepants, where available, first‐line treatment options for the acute treatment of migraine. Triptans may be prescribed in the absence of contraindications, significant risk of cardiovascular disease, or risk for or history of medication‐overuse headache. In those who have contraindications or precautions for triptans, those who do not have an adequate response to triptans, and those unable to tolerate them, gepants are often an appropriate option. The efficacy and safety of gepants for the acute treatment of migraine has been established through clinical trials and open‐label extension studies and based on real‐world evidence. Gepants have demonstrated efficacy and tolerability in triptan insufficient responders, perhaps because of their distinct mechanisms of action. Additionally, the safety of gepants, including relative cardiovascular safety, is supported in pivotal controlled trials and open‐label extension trials. In experimental settings and through their use as preventive treatment for migraine, gepants appear unlikely to produce medication‐overuse headache. In addition, one gepant (ubrogepant) has demonstrated efficacy in preventing headache onset when given during the prodrome, a finding that has not been demonstrated for triptans. A single‐arm, open‐label study of naratriptan given during the prodrome suggested fewer subsequent headaches, but interpretation is limited because there was no contemporaneous control group. Limited head‐to‐head clinical trials comparing gepants and triptans have not demonstrated significant differences. Prescribers of both triptans and gepants should be mindful of potential drug–drug interactions. Conclusions Key advantages of gepants include their favorable tolerability, efficacy for the acute treatment of both the prodromal/premonitory phase (ubrogepant) and the headache phase of migraine (ubrogepant, rimegepant, zavegepant), lack of cardiovascular contraindications, and lack of association with medication‐overuse headache. Disadvantages include limitations due to cost and access and CYP3A4 drug interactions for most gepants. Together, the advantages may help to optimize patient care and lead to better persistence and effectiveness in a real‐world setting. Head‐to‐head studies are needed to clarify the comparative effectiveness of triptans and gepants.

ABSTRACT Background Preoperative vascular embolization (PVE) is commonly used in managing juvenile nasopharyngeal angiofibroma (JNA) to improve outcomes. However, few studies have evaluated how embolization patterns and vascular features affect prognosis. Methods A 15‐year retrospective review was performed on 44 patients with JNA undergoing surgery at one institution. Data included demographics, vascular supply, embolization techniques, surgical outcomes, and recurrence. Results Forty‐three patients underwent PVE. Most tumors were embolized transarterially (93.0%) using polyvinyl alcohol‐based agents (79.1%). The internal maxillary artery was most commonly embolized (93.0%). Internal carotid artery supply was present in 34.9%, and more than two vessels were embolized in 23.3%. Postembolization tumor blush occurred in 60.5%, with a median of 5% of the pre‐embolization blush remaining after embolization. Neither internal carotid involvement, number of vessels embolized, nor residual blush significantly impacted operative time, surgical outcomes, or recurrence. Conclusion With effective embolization, vascular complexity might not affect JNA resection outcomes. Multicenter studies are required to confirm those findings.

Abstract Background Computational modeling is a tool being deployed for orthopaedic solutions but its use in the hand and wrist remains limited. This work used a model to simulate a clinically relevant provocative scaphoid shift maneuver (SSM) with different levels of scapholunate interosseous ligament (SLIL) injuries to observe the effect on different metrics. Methods A personalized model simulated the full SSM motion cycle from ulnar deviation with extension to radial deviation with flexion informed by the participant’s motion obtained from dynamic computed tomography. Models repeated the SSM under different levels of SLIL injury and reported changes in joint kinematics, contact mechanics, and ligament forces. Results The fully injured model increased scaphoid dorsal translation, flexion, and radial deviation compared to the intact condition and caused a subluxation of the scaphoid. Radioscaphoid contact areas were approximately 200% greater in the fully injured model compared with all others and the fully injured model was the only condition where contact force decreased across the motion cycle. Ligament forces in the intact condition were on average 33.0 N and 54.2 N for the volar and dorsal SLIL, respectively. Lastly, the long radiolunate, an extrinsic stabilizer, had forces that increased following SLIL injury. Conclusions Computational models can successfully recreate clinically observed behaviors of an SSM, including scaphoid subluxation, while providing new insights via quantification of contact mechanics and ligament forces. Contact mechanics metrics may be important for understanding the long-term progression of untreated SLIL injuries to osteoarthritis. Additionally, ligament force metrics may explain the progression of SLIL injuries from volar SLIL to dorsal SLIL and highlight the importance of repairing extrinsic stabilizers of the joint, due to increased force sharing following SLIL injury. This work provides a pathway to future studies investigating the effects of SLIL injury and repair, both acutely and chronically.

ABSTRACT Background Prolonged QT interval is common in end‐stage renal disease (ESRD) on dialysis, but its long‐term cardiovascular (CV) implications remain unclear. Methods Using TriNetX network (2010–2024), we identified adults with ESRD on dialysis and categorized them by QTc status. After 1:1 propensity score matching ( n = 3428/group), outcomes (hazard ratio [HR]) were assessed using Cox regression. Results Prolonged QTc (> 500 ms) was associated with higher risk of all‐cause mortality (HR 1.67; p < 0.001), MACEs (HR 1.40; p < 0.001), cardiac arrest (HR 1.75; p < 0.001), sustained ventricular arrhythmia (HR 1.66; p < 0.001), new‐onset atrial fibrillation (HR 1.12; p = 0.01), and acute myocardial infarction (HR 2.19; p < 0.001). Conclusions In ESRD patients on dialysis, prolonged QT interval was independently associated with adverse CV outcomes and mortality.
