BACKGROUND AND OBJECTIVES: The therapeutic approach for small- and medium-sized vestibular schwannoma (VS) with normal hearing function remains controversial, with limited comparative data regarding hearing outcomes after stereotactic radiosurgery (SRS) or observation (OBS). We evaluated the serviceable hearing preservation, loss of American Academy of Otolaryngology-Head and Neck Surgery class A hearing, and tumor control (TC) across individuals with Koos grade I and II VSs and normal hearing at presentation who underwent SRS or OBS. METHODS: In this multicenter international study, we retrospectively analyzed the hearing, radiological, and neurological outcomes of patients who underwent SRS (SRS group) or OBS (OBS group). The cohorts were matched using propensity scores based on age, sex, tumor volume, pure-tone average, and speech discrimination score at a 1:1 ratio without replacement. RESULTS: After matching, each group comprised 57 patients. The median follow-up was 49 and 37 months for the SRS and the OBS groups, respectively ( P = .3). The 5- and 9-year serviceable hearing preservation rates in the SRS group were 76.2% and 42.4% vs 56.1% and 16.8% in the OBS group ( P = .17). Class A preservation occurred in 57.9% (33/57) of the SRS and 52.6% (30/57) of the OBS cohorts ( P = .70). Regarding the TC rates, SRS was associated with significantly higher TC rates ( P < .0001). CONCLUSION: We found that SRS is significantly superior regarding TC and provided noninferior hearing outcomes compared with OBS in VS patients with American Academy of Otolaryngology-Head and Neck Surgery class A hearing at presentation. Therefore, we suggest performing SRS in individuals with VS and normal hearing function.

Abstract Background and Aims Intestinal ultrasound (IUS) is increasingly used to monitor treatment efficacy in inflammatory bowel disease (IBD) trials. However, standardized definitions for response, remission, and optimal assessment timing remain undefined. An international expert consensus meeting was held to establish IUS endpoints for clinical trials. Methods A panel of 35 international gastroenterologists and radiologists participated in a modified Delphi process, reviewing the literature and developing consensus statements. Agreement was defined as at least 75% consensus. Results Consensus was reached on 150 statements across four domains: general IBD (30 statements), luminal Crohn’s disease (CD) (43), perianal CD (51), and ulcerative colitis (UC) (26). For luminal CD and UC, ultrasound response was defined by: (1) a ≥25% reduction in bowel wall thickness (BWT) from baseline, or (2) multifactorial improvement, combining BWT reduction with ≥1 grade decrease in color Doppler signal (CDS) or another IUS parameter. Assessments were set at weeks 4-8 for the colon and week 12 for the terminal ileum. Ultrasound remission in luminal CD was defined as: (1) BWT normalization (≤3 mm) or (2) normalization of multiple parameters, including BWT, CDS, and all other IUS parameters. Similar remission criteria were proposed for UC, but the sigmoid BWT normal range (3-4 mm) remained uncertain. The bowel ultrasound score (BUSS) for CD and the Milan ultrasound criteria (MUC) for UC were supported as standardized scoring systems for trials. Conclusion This consensus provides standardized IUS definitions to enhance consistency in IBD trials, supporting the integration of IUS in future research.

ABSTRACT Introduction Etripamil is a fast‐acting intranasally self‐administered calcium‐channel blocker developed for termination of paroxysmal supraventricular tachycardia (PSVT). Prior studies have demonstrated safety and efficacy of etripamil for PSVT termination following an initial medically supervised test dose during sinus rhythm. NODE‐303 is an open‐label, single‐arm study that evaluated etripamil for multiple, at‐home PSVT episodes, without test dose before first use. Methods Patients applied an ECG monitor at symptom onset and self‐administered etripamil (70 mg) if a vagal maneuver was unsuccessful. ECG monitoring occurred for ≥ 1 h following study drug administration. A repeat 70‐mg dose was introduced during the study for symptoms persisting 10 min after the first dose. Safety measures included treatment‐emergent adverse events (TEAEs) and ECG arrhythmia‐surveillance. Efficacy measures were captured for PSVT termination during treatment of each of the multiple episodes. Results 1054 perceived PSVT episodes were etripamil‐treated in 503 of 1116 patients enrolled. TEAEs within 24 h were mostly mild or moderate and localized: 30.2% of patients experienced nasal discomfort, nasal congestion (13.9%), rhinorrhea (13.1%), epistaxis (7.4%). TEAE frequencies decreased across multiple PSVT episodes and were similar for single versus repeat doses. For first PSVT episodes, 70.5% of patients converted to sinus rhythm by 60 min post etripamil (median time to conversion = 18.3 min [14.2–25.6]). Conversion in earlier episodes was consistently predictive of conversion in subsequent episodes. Conclusions Etripamil nasal spray self‐administered in a real‐world setting was well tolerated, effective, and had a consistent safety profile as a single‐ or repeat‐dose regimen across multiple PSVT episodes.

Background and importance Emergency airway management in the emergency department (ED) is a high-risk procedure associated with patient outcomes. First-attempt success is a widely recognized quality metric, as multiple attempts are associated with an increased risk of peri-intubation complications. In Brazil, where emergency medicine is a recently established specialty, many ED are staffed by physicians without formal emergency medicine training. The association between emergency medicine training and intubation outcomes in this setting has not been well characterized. Objective To assess the association of physician specialty with first-attempt success and immediate peri-intubation complications in Brazilian EDs. Design Secondary analysis of a multicenter, prospective cohort study from the Brazilian Airway Registry Cooperation. Setting and participants This study included adult patients who underwent tracheal intubation in EDs between March 2022 and April 2024. Patients were excluded if the intubation occurred outside the ED, during cardiopulmonary resuscitation, or for elective procedures. Intubations performed by medical students were also excluded. Physicians were categorized by specialty as emergency medicine or nonemergency medicine. Outcome measures and analysis The primary outcome was first-attempt success; secondary outcomes included peri-intubation complications (severe hypoxemia, hemodynamic instability, and cardiac arrest). Multivariable logistic regression was used to assess the association between physician specialty and outcomes. Main results Among 2582 patients, 1087 (42.1%) were intubated by emergency physicians and 1495 (57.9%) by other physicians (mainly internal medicine and surgery). Intubations by emergency physicians were associated with a higher rate of first-attempt success [80.4 vs. 70.9%, adjusted odds ratio [aOR]: 1.63, 95% confidence interval (CI): 1.34–1.97]. There was also a higher odds of intubations without major complications (aOR: 1.20, 95% CI: 1.01–1.42). Conclusion In this study, there was a higher rate of first-attempt success in intubations performed by board-certified emergency physicians compared with other physicians working in Brazilian EDs.

Abstract Rationale Inflammation is central to chronic obstructive pulmonary disease (COPD) pathogenesis but incompletely represented in COPD prognostic models. The neutrophil-to-lymphocyte ratio (NLR) is a readily available inflammatory biomarker. Objectives To explore the associations of NLR with smoking status, clinical features of COPD, and future adverse outcomes. Methods We analyzed NLR calculated from the complete blood count of participants who currently or formerly smoked (n = 2,624) and tobacco-naive control subjects (n = 187) in the SPIROMICS multicenter observational cohort study. We assessed the stability of NLR at 6 weeks and 1 year, the association with select blood biomarkers, and the impact of smoking on NLR and cell counts. We stratified participants by NLR quartiles to compare cross-sectional clinical features at enrollment, prospectively observed exacerbations at 1 year, and mortality during longitudinal follow up. Results Higher NLR quartiles were broadly associated with more severe clinical features of COPD. NLR values were repeatable at 6 weeks (intraclass correlation coefficient, 0.74) and 1 year (intraclass correlation coefficient, 0.62). The impact of smoking on NLR varied with the severity of airflow limitation, mediated by an interaction between smoking, forced expiratory volume in 1 second percent predicted, and neutrophil counts but not lymphocyte counts. The highest NLR quartile (&gt;3.11) was associated with an increased risk of exacerbation over 1 year (adjusted odds ratio, 1.51; 95% confidence interval, 1.18, 1.92) and increased risk of mortality (adjusted hazard ratio, 1.41; 95% confidence interval, 1.20, 1.66) compared with quartiles 1–3. Conclusions Elevated NLR in stable COPD is a widely available biomarker associated with increased risk for exacerbation and death. The impact of cigarette smoking on NLR varies with disease severity.

OBJECTIVE Open resective surgery (ORS) has become the standard of care for focal drug-resistant epilepsy (DRE). However, minimally invasive surgical alternatives, such as laser interstitial thermal therapy (LITT), have also been shown to be safe and effective. A meta-analysis comparing both treatments is warranted to assess the benefits of each modality for focal DRE. METHODS A literature search was conducted until March 14, 2024, to identify studies comparing LITT and ORS in patients with DRE. The primary outcomes included seizure freedom (SF), length of hospital stay (LHS), and complication rate (CR). Subgroup analyses were performed based on age, epilepsy etiology, and propensity score–matched (PSM) studies. RESULTS Of 558 articles, 15 cohort studies met the authors’ inclusion criteria, encompassing 3873 patients for analysis. The rate of SF in the LITT group was 52.5% (95% CI 0.453–0.597, I 2 = 47.4%) and 67.1% (95% CI 0.602–0.739, I 2 = 57.4%) for the ORS group. LITT showed a significantly lower rate of SF compared to ORS (risk ratio [RR] 0.78, 95% CI 0.70–0.88, p ≤ 0.0001). However, when PSM studies (RR 0.85, 95% CI 0.63–1.15, p = 0.30) and studies on patients with temporal lobe epilepsy (TLE) (RR 0.88, 95% CI 0.67–1.14, p = 0.34) were analyzed, the SF rates were similar. Patients who underwent LITT had a significantly shorter LHS (mean difference 2.95 days, 95% CI 1.12–4.78, p < 0.00001), lower CR (RR 0.54, 95% CI 0.37–0.79, p < 0.002, I 2 = 32%), lower rate of ischemic stroke (RR 0.15, 95% CI 0.04–0.65, p = 0.01), and lower rate of permanent neurological deficits (RR 0.13, 95% CI 0.05–0.36, p < 0.0001). CONCLUSIONS Across unmatched studies evaluating focal DRE, ORS showed a higher rate of SF. However, pooled matched-cohort analyses showed no difference between interventions in achieving SF, a trend also noted in the authors’ PSM TLE sample. LITT, however, offered significantly shorter LHS and lower CRs. Future prospective studies should match patient populations to control for confounding factors and assess key outcomes, such as postoperative neurocognitive follow-up and quality of life measurements, in order to fully evaluate the risks and benefits of each approach.

Objective: Patients with chronic pancreatitis commonly experience abdominal pain, anxiety, depression, reduced mobility, and difficulty performing daily activities or maintaining employment. These factors contribute to diminished quality-of-life and high healthcare utilization. This study aims to explore the relationship between specific quality-of-life domains among patients with chronic pancreatitis. Methods: A 55-item online survey was administered to patients with the diagnosis of chronic pancreatitis at 3 Mayo Clinic sites from December 26, 2023, to December 26, 2024. The survey included validated questions assessing demographic, clinical, and quality-of-life metrics using EuroQol 5-Dimension 5-Level instrument—a standardized assessment tool that evaluates 5 key health dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Results: Of the 298 patients with chronic pancreatitis who completed the survey, employed patients had decreased odds of reporting problems with mobility (odds ratio [OR] = 0.45, P < .05), self-care (OR = 0.26, P < .01), usual activities (OR = 0.47, P < .05), and anxiety/depression (OR = 0.41, P < .05). Similarly, older patients had decreased odds of reporting problems with self-care (OR = 0.91, P < .01), usual activities (OR = 0.96, P < .01), pain/discomfort (OR = 0.96, P < .01) and anxiety/depression (OR = 0.92, P < .01). However, Medicare patients had greater odds of reporting problems with self-care (OR = 5.54, P < .01) and pain/discomfort (OR = 2.58, P < .05). Conclusions: Chronic pancreatitis impacts multiple dimensions of quality-of-life beyond pain. The EuroQol 5-Dimension 5-Level tool enables comprehensive assessment of physical and mental health. Our findings highlight key associations between patient characteristics and quality-of-life domains, supporting the need for individualized, deficit-targeted interventions. These results also suggest a potential role for vocational rehabilitation in promoting functional recovery and enhancing overall well-being in individuals with chronic pancreatitis.

Abstract We investigated the influence of 55 583 autophagy-related single-nucleotide polymorphisms (SNPs) on chronic lymphocytic leukemia (CLL) risk across 4 independent populations comprising 5472 CLL cases and 726 465 controls. We also examined their impact on overall survival (OS), time to first treatment (TTFT), autophagy flux, and immune responses. A meta-analysis of the 4 populations identified, to our knowledge, for the first time, significant associations between CDKN2A (rs3731204) and BCL2 (rs4940571, rs12457371, and rs1026825) SNPs and CLL risk, with CDKN2A showing the strongest association (P = 1.57 × 10−12). We also validated previously reported associations for FAS, BCL2, and BAK1 SNPs with CLL risk (P = 4.73 × 10−21 to 3.39 × 10−9). The CDKN2Ars3731204 and FASrs1926194 SNPs associated with increased CDKN2A and ACTA2 messenger RNA expression levels in the whole blood and/or lymphocytes (P = 5.1 × 10−7, P = 1.58 × 10−21, and P = 7.8 × 10−41), although no significant effect on autophagy flux was observed. However, associations were found between CDKN2A, BCL2, and FAS SNPs and various T-cell subsets, cytokine production, and circulating concentrations of interferon gamma, tumor necrosis factor–related apoptosis-inducing ligand, CD40, chemokine ligand 20, and interleukin-2 receptor subunit β proteins (P ≤ .005). No significant association was detected between autophagy variants and OS or TTFT, suggesting that these variants drive disease initiation rather than progression. In conclusion, this study identified 4 novel associations for CLL and provided insights into the biological pathways that influence CLL development.
