Background: Acute ischemic stroke (AIS) from distal medium vessel occlusion (DMVO) presents unique treatment challenges. Mechanical thrombectomy (MT) is emerging as a viable option for these patients, yet the role of pre-stroke aspirin treatment is unclear. This study evaluates the impact of pre-stroke low-dose aspirin on outcomes in DMVO patients undergoing MT. Methods: We conducted a multinational, multicenter, propensity score-weighted analysis within the Multicenter Analysis of primary Distal medium vessel occlusions: effect of Mechanical Thrombectomy (MAD-MT) registry. Patients with AIS due to DMVO, treated with MT, were included. We compared outcomes between patients on pre-stroke low-dose aspirin (75–100 mg) and those not on antiplatelet therapy. The primary outcome was functional independence at 90 days (modified Rankin Scale (mRS), 0–2). Secondary outcomes included excellent functional outcome at 90 days (mRS, 0–1), mortality, and day 1 post-MT National Institutes of Health Stroke Scale (NIHSS) score. Safety outcomes focused on hemorrhagic complications, including symptomatic intracerebral hemorrhage (sICH). Results: Among 1354 patients, 150 were on pre-stroke low-dose aspirin. After applying inverse probability of treatment weighting (IPTW), aspirin use was associated with significantly better functional outcomes (mRS, 0–2: odds ratio (OR) = 1.89, 95% confidence interval (CI) = 1.14 to 3.12) and lower 90-day mortality (OR = 0.56, 95% CI = 0.32 to 1.00). The aspirin group had lower NIHSS scores on day 1 (β = −1.5, 95% CI = −2.8 to −0.27). The sICH rate was not significantly different between the groups (OR = 0.92, 95% CI = 0.60 to 1.43). Conclusions: Pre-stroke low-dose aspirin was associated with improved functional outcomes and reduced mortality in patients with DMVO undergoing MT, without a significant increase in sICH. These findings suggest that low-dose aspirin may be safe and associated with more frequent excellent outcomes for this patient population. Further prospective studies are needed to validate these results and assess long-term outcomes.

Background Current randomized controlled trials are investigating the efficacy and safety of mechanical thrombectomy (MT) in patients with medium vessel occlusion (MeVO) stroke. Whether best medical management (MM) is more efficient than unsuccessful vessel recanalization during MT remains unknown. Methods This was a retrospective cohort study using data from 37 academic centers across North America, Asia, and Europe between September 2017 and July 2021. Only patients with occlusion of the distal branches (M2 and M3) of the middle cerebral artery territory were included. Unsuccessful MT was defined as a modified Thrombolysis in Cerebral Infarction score of 0–2a. Propensity score matching was used to control for confounders. The primary outcome was functional independence, defined as a modified Rankin Scale (mRS) score of 0–2 at 90 days after treatment. Multivariable regression analysis was used to assess factors associated with the primary outcome. Results Of 2903 patients screened for eligibility, 532 patients were analyzed (266 per group) after propensity score matching. The MM group had superior functional outcomes, with 32% achieving mRS 0–1 at 90 days compared with 21% in the MT group (P=0.011). Patients in the MM group also had significantly lower rates of symptomatic intracranial hemorrhage (sICH) (3.4% vs 16%, P<0.001) and any hemorrhage (18% vs 48%, P<0.001). On multivariable regression, unsuccessful MT was associated with reduced odds of functional independence (OR 0.50, 95% CI 0.29 to 0.85, P=0.011) and increased odds of sICH (OR 4.32, 95% CI 1.84 to 10.10, P<0.001). Mortality rates were similar between groups (27% in MM vs 29% in MT, P=0.73). Conclusion Unsuccessful MT for MeVO was linked to worse outcomes than best MM. These findings highlight the risks of prolonged attempts and emphasize the importance of efficient procedural decision-making to reduce complications and improve patient outcomes.

Abstract Introduction We describe the safety of sotorasib monotherapy in patients with KRAS G12C-mutated advanced non-small cell lung cancer (NSCLC) and discuss practical recommendations for managing key risks. Methods Incidence rates of treatment-related adverse events (TRAEs) were pooled from 4 clinical trials: CodeBreaK 100 (NCT03600883), CodeBreaK 101 (NCT04185883), CodeBreaK 105 (NCT04380753), and CodeBreaK 200 (NCT04303780) and graded according to CTCAE v5.0. Adverse events were deemed sotorasib-related per investigator causality assessment. Results In the pooled population (n = 549), TRAEs were reported in 388 (70.7%) patients (grade 1: 124 [22.6%]; grade 2: 117 [21.3%]; grade ≥ 3: 147 [26.8%]). Gastrointestinal and hepatic TRAEs, including diarrhea (171 [31.1%]), nausea (80 [14.6%]), elevated alanine aminotransferase (ALT; 68 [12.4%]), and elevated aspartate aminotransferase (AST; 67 [12.2%]) were the most common (≥10%). Dose interruption and dose reduction of sotorasib resulted in the resolution of &gt;90% of diarrhea events; median time to resolution were 18.0 days and 22.0 days, respectively. Similar trends were observed for elevated ALT and AST events. Patients who stopped immunotherapy &lt;3 months before initiating sotorasib had a higher incidence of treatment-related hepatotoxicity (80/240 [33.3%]) than those who stopped immunotherapy ≥3 months before initiating sotorasib (26/188 [13.8%]). Treatment-related pneumonitis/interstitial lung disease (ILD) and corrected QT (QTc) prolongation were observed in 9 (1.6%) and 4 (0.7%) patients, respectively. Two (0.4%) patients died with TRAEs, 1 with ILD whose ultimate cause of death was disease progression, and the other with an unknown cause. Conclusions Sotorasib has a well-characterized safety profile in patients with KRAS G12C-mutated advanced NSCLC, and key risks are manageable with dose modification.

Abstract Background Tumor necrosis factor-like ligand 1A (TL1A) is upregulated in inflammatory bowel disease and believed to promote inflammation and intestinal fibrosis. RO7790121, an anti-TL1A antibody, showed promising results in the phase IIa TUSCANY trial.1 Here we report post-hoc analyses of patient-reported outcomes from the TUSCANY-2 trial. Methods This phase IIb, multicenter, randomized, double-blind, treat-through, dose-ranging study evaluated RO7790121 in patients (pts) aged 18–75 years with moderately to severely active ulcerative colitis (UC) (total Mayo score [MS] ≥6, endoscopic subscore ≥2). Pts were randomized to receive subcutaneous (SC) RO7790121 50mg, 150mg, 450mg or matched placebo (PBO) monthly during the 12-week induction period, and SC RO7790121 50mg, 150mg or 450mg monthly during the 40-week treat-through maintenance period. To assess efficacy of RO7790121 in supporting pts achieving early symptomatic improvement, rectal bleeding (RB), stool frequency (SF) and partial modified MS (RB+SF) were evaluated at baseline and Weeks 2, 4, 8, 12 and 14. The exploratory endpoint of symptomatic remission, defined as a RB subscore of 0 and a SF subscore of 0 or 1, was assessed throughout induction. Safety was assessed throughout the study. Results Overall, 245 pts received ≥1 dose of RO7790121 or PBO. At Week 2, pts receiving RO7790121 were more likely to report a RB subscore of 0 (34% RO7790121; 20% PBO) and less likely to report a RB subscore of 2 or 3 (25% RO7790121; 40% PBO) (Figure). Improvements in SF increased from Week 2 and throughout induction, with ~60% of pts receiving RO7790121 reporting a SF subscore of 0 or 1 at Weeks 12 and 14, vs ~40% for PBO. Greater rates of symptomatic remission were observed in pts receiving RO7790121 vs PBO throughout induction and from Week 2 (17.5% RO7790121; 8.9% PBO) (Table). Treatment-emergent adverse events (TEAEs) were reported during induction in 117/245 pts, the most common (reported in ≥5% of pts in any treatment group) were nausea, urinary tract infection and UC (highest in the 50mg arm), anemia (highest in the placebo arm) and fatigue, headache and pyrexia (highest in the 450mg arm). Serious TEAEs were reported in ten pts during induction (PBO=4; 50mg=3; 450mg=3); two were treatment related (PBO=1; 450mg=1). There were six treatment discontinuations due to TEAEs and a generally similar safety profile was observed during the maintenance period. Conclusion Greater and earlier improvements in RB and SF were observed in pts receiving RO7790121 vs PBO. These results indicate early symptom relief and a favorable safety profile for pts treated with RO7790121, supporting its further clinical development.

Importance There is a lack of long-term efficacy and safety data on hereditary transthyretin amyloidosis with polyneuropathy (hATTR-PN) and on RNA interference (RNAi) therapeutics in general. This study presents the longest-term data to date on patisiran for hATTR-PN. Objective To present the long-term efficacy and safety of patisiran in adults with hATTR-PN. Design, Setting, and Participants This global open-label extension (OLE) of the APOLLO randomized clinical trial and phase 2 OLE study enrolled patients from 43 hospitals or clinical centers across 19 countries between July 2015 and August 2017, with follow-up until November 2022. Of 212 eligible patients with hATTR who completed the phase 3 APOLLO or phase 2 OLE parent studies, 211 enrolled in and 138 completed the global OLE. Intervention Patisiran, 0.3 mg/kg, intravenously once every 3 weeks for up to 5 years. Main Outcomes and Measures Outcomes evaluated at year 5 of the global OLE included disability (polyneuropathy disability [PND] score); polyneuropathy severity (Neuropathy Impairment Score [NIS]), nutritional status (modified body mass index [mBMI]), quality of life (Norfolk Quality of Life–Diabetic Neuropathy [Norfolk QOL-DN]), and Rasch-Built Overall Disability Scale (R-ODS), with no statistical hierarchy. Safety, survival probability, and mortality were also assessed. Results At the global OLE baseline, the mean (SD) age was 61.3 (12.3) years, and 156 patients (73.9%) were male. In 138 patients completing the study, PND scores remained stable or improved in 89 patients (65.0%), NISs showed a mean (SD) change of 10.9 (14.7), and mean (SD) mBMI (calculated as weight in kilograms divided by height in meters squared times serum albumin in grams per liter) increased by 46.4 (120.7) over 5 years from baseline. Norfolk QOL-DN and R-ODS scores showed mean (SD) changes of 4.1 (16.7) and –3.7 (6.2), respectively. Adverse events (AEs) leading to study withdrawal occurred in 47 patients (22.3%). Infusion-related reactions were the most common treatment-related AE (n = 34 [16.1%]). Overall, 41 patients (19.4%) died during the study. Patisiran treatment in the parent study and low familial amyloid polyneuropathy score at parent study baseline were associated with significantly improved survival. Conclusions and Relevance In the longest study of an RNAi therapeutic for any disease, patisiran treatment resulted in modest changes for patients with hATTR-PN with an acceptable safety profile. These results highlight the importance of initiating early treatment for hATTR and the potential of RNAi therapeutics in medicine. Trial Registration ClinicalTrials.gov Identifier: NCT02510261

OBJECTIVE Cervical spondylotic myelopathy (CSM) shows varying levels of improvement after surgical treatment. While some patients improve soon after surgery, others may take months to years to show any signs of improvement. The goal of this study was to evaluate postoperative improvement, patient-reported outcomes, and patient satisfaction up to 2 years after surgical treatment for CSM, which will help optimize the current treatment strategies and effectively manage patient expectations. METHODS This was a retrospective study of prospectively collected data using the Quality Outcomes Database. The primary outcomes of interest were achievement of the minimal clinically important difference (MCID) for the numeric rating scale for neck and arm pain, modified Japanese Orthopaedic Association, Neck Disability Index, and EQ-5D scores and postoperative satisfaction (North American Spine Society scale). Early and sustained improvement was defined as MCID achievement in at least one patient-reported outcome measure (PROM) at the 3-, 12-, and 24-month follow-ups. Transient improvement was defined as MCID achievement only at the 3-month and/or 12-month follow-up but not at the 24-month follow-up. Late improvement was defined as MCID achievement in at least one PROM only at the 24-month follow-up. RESULTS There were 630 patients included in the comparative analysis. A total of 463 (73.5%) patients achieved early and sustained improvement, 105 (16.7%) patients experienced transient improvement with subsequent decline, 25 (4.0%) patients reported late improvement, and 37 (5.9%) patients did not report any clinically meaningful improvement after surgery. Patients with an anterior approach were more likely to be in the early and sustained improvement group. African American patients (OR 2.98, 95% CI 1.14–7.76; p = 0.03) were more likely to report late improvement when compared with White patients. The overall satisfaction rate at the 24-month follow-up was 87.8%. CONCLUSIONS These findings indicate that 73.5% of patients achieve early and sustained improvement, and 87.8% of patients are satisfied with surgery 24 months postoperatively.

Fungal infections represent a significant global health challenge. Candida albicans is a particularly widespread pathogen, with both molecular and biofilm-based mechanisms making it resistant to or tolerant of available antifungal drugs. This study reports a combination therapy, active against C. albicans, utilizing terbinafine and essential oils incorporated into a gelatin-based nanoemulsion system (T-GNE). Eugenol and methyl eugenol/terbinafine T-GNEs had an additive efficacy, while carvacrol (CT-GNE) worked synergistically with terbinafine, providing effective antifungal treatment with minimal mammalian cell toxicity. Confocal microscopy demonstrated that CT-GNE penetrated the dense C. albicans biofilm and disrupted the fungal cell membrane. Overall, the combination of essential oils with terbinafine in GNE provided a promising treatment for fungal biofilms.
