Endovascular intervention for acute stroke in the very late window: A meta-analysis of 90-day mRS and procedural outcomes.

OBJECTIVE: This study investigates the effectiveness of Endovascular Therapy (EVT) in very late windows (beyond 24&#xa0;h) for patients with ischemic stroke, focusing on 90-day mortality, functional outcomes, and procedural success. METHODS: This systematic review and meta-analysis followed Cochrane and PRISMA guidelines to evaluate the effectiveness of endovascular therapy (EVT) in acute ischemic stroke patients. Literature from PubMed, Embase, Web of Science, and Scopus was reviewed using specific keywords. Studies included those after 2000 with outcomes such as functional independence (mRS 0-2), mortality, TICI scores, and neurological improvements. RESULTS: The data findings reveal mixed outcomes across studies on EVT beyond 24&#xa0;h. Sarraj et al. (2023) found a significant improvement in functional independence with EVT (38% vs. 10%, p&#xa0;<&#xa0;0.05), despite an increased risk of sICH. The forest plots for mRS and procedural outcomes show some significant results, such as Sarraj (2023) for mortality (p&#xa0;<&#xa0;0.05), but most other studies indicated no statistically significant differences (p&#xa0;>&#xa0;0.05). CONCLUSION: The study has concluded that Endovascular Therapy (EVT) beyond 24&#xa0;h can improve functional outcomes and reduce mortality in selected ischemic stroke patients, though patient selection remains crucial.

Endovascular thrombectomy versus best medical therapy for acute vertebrobasilar artery occlusion in patients with low NIHSS scores: a&#xa0;meta-analysis.

OBJECTIVE: The efficacy of endovascular thrombectomy (EVT) for acute vertebrobasilar artery occlusion (VBAO) presenting with mild symptoms (National Institutes of Health Stroke Scale [NIHSS] score &#x2264;10) remains uncertain. This meta-analysis aimed to compare the effectiveness and safety of EVT versus best medical therapy (BMT) in this population. METHODS: We systematically searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials from inception to September 2025 for comparative studies. The primary outcome was 90-day excellent functional outcome (modified Rankin Scale [mRS] score 0-1). Secondary outcomes included functional independence (mRS 0-2), symptomatic intracranial hemorrhage (sICH), and all-cause mortality. Pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated using a random-effects model. RESULTS: Seven observational studies involving 3,107 patients were included. In unadjusted analyses, EVT was associated with a higher rate of excellent functional outcome (OR 2.17; 95% CI 1.58-2.96) but not with functional independence (OR 1.58; 95% CI 0.90-2.77). After adjustment for confounders, EVT was associated with higher rate of excellent functional outcome (OR 2.86; 95% CI 1.89-4.31) and functional independence (OR 1.91; 95% CI 1.01-3.62). Safety outcomes including sICH and mortality did not differ significantly between groups. CONCLUSION: In patients with acute VBAO and mild symptoms, EVT may be associated with superior functional outcomes compared to BMT alone, without a significant increase in procedural risks. These findings suggest a potential role for EVT in selected patients with low NIHSS scores and underscore the need for confirmation in randomized trials.

Occlusion site and outcomes in intra-arterial tenecteplase after successful endovascular therapy: a secondary analysis of the ANGEL-TNK trial.

BACKGROUND: Endovascular thrombectomy achieves macroreperfusion in large vessel occlusion (LVO) stroke, but only one-quarter of patients had excellent functional outcome. Adjunct intra-arterial (IA) tenecteplase could further improve the treatment effect, yet its efficacy across internal carotid artery (ICA) versus middle cerebral artery (MCA) M1/M2 occlusion remains unclear. OBJECTIVE: To evaluate whether IA tenecteplase improves 90-day functional outcomes in LVO patients stratified by occlusion site (ICA, MCA M1, MCA M2). METHODS: Prespecified secondary analysis of the ANGEL-TNK trial (multicenter, randomized, open-label, blinded endpoint) in 19 Chinese stroke centers. Participants were enrolled who had anterior circulation LVO, 4.5-24&#x2009;hours from symptom onset, and CT angiography (CTA)/magnetic resonance angiography (MRA)-proven ICA, M1, or M2 occlusion. INTERVENTION: Randomization (1:1) to IA tenecteplase (0.125&#x2009;mg/kg) or standard medical management after expanded Thrombolysis in Cerebral Infarction (eTICI) 2b50-3 reperfusion. MAIN OUTCOME MEASURE: The primary outcome was the rate of 90-day modified Rankin Scale (mRS) 0-1. RESULTS: There were 256 patients in the trial, including 71 (27.7%) ICA, 122 (47.6%) MCA M1, and 62 (24.2%) MCA M2. ICA occlusion patients treated with IA tenecteplase had higher rates of 90-day mRS 0-1 (39.4% vs 13.2%; relative risk (RR) 2.99; 95%&#x2009;CI 1.51 to 5.96; p=0.002) and mRS 0-3 (54.5% vs 42.1%; RR 1.30; p=0.048) versus controls, with a significant shift toward better mRS scores (median 3 (IQR 1-4) vs 4 (2-6); odds ratio (OR) 2.26; p<0.001). Post hoc analysis showed higher eTICI progression in ICA patients (51.5%) versus MCA M1 (37.9%) and M2 (25.7%). IA tenecteplase had a lower any intracranial hemorrhage within 48 hours in ICA patients (15.2% vs 39.5%; RR 0.38; p<0.001) compared with standard medical management. No significant benefits were observed in the MCA M1/M2 subgroups, and interaction effects were significant between ICA and MCA segments for functional outcomes and safety. CONCLUSIONS AND RELEVANCE: IA tenecteplase had a better functional outcome and lower hemorrhage risk in ICA occlusion compared with standard medical management but not in MCA M1/M2. Occlusion site is a critical determinant of response to IA tenecteplase. A pooled analysis of IA tenecteplase stratified by occlusion site strata is warranted.

Transverse Tibial Transport for Limb Salvage in Ischemic Lower Extremity Disease: Technique, Mechanisms, and Clinical Outcomes-A Systematic Review.

Transverse tibial transport (TTT) is a surgical technique derived from Ilizarov's distraction osteogenesis principles that stimulates angiogenesis and microcirculatory regeneration in the ischemic lower limb without directly manipulating macrovascular anatomy. By creating a proximal tibial cortical bone window and distracting it transversely using an external fixator, TTT triggers converging cascades of growth factor release, endothelial progenitor cell mobilization, and immunomodulation that translate into improved distal limb perfusion and wound healing. Combined TTT plus endovascular therapy improves amputation-free survival versus endovascular therapy alone. Prospective randomized trials and standardized international protocols are needed to consolidate TTT's role in multidisciplinary limb salvage pathways.

Blood pressure management after endovascular thrombectomy in acute ischemic stroke: association with symptomatic intracranial hemorrhage and functional outcome at 3&#xa0;months.

BACKGROUND: No clear consensus exists on ideal systolic blood pressure (SBP) targets after endovascular thrombectomy (EVT) following an acute ischemic stroke (AIS). This study investigated the association between SBP parameters within the first 24&#xa0;h after EVT and 3-month functional outcomes and the risk of symptomatic intracranial hemorrhage (sICH). METHODS: We retrospectively collected and prospectively followed clinical, and radiological data for patients undergoing EVT for AIS from 2016 to 2024, including 2-hourly BP measurements during the first 24&#xa0;h and SBP variability assessed by standard deviation (SD) and coefficient of variation (CV). Outcomes included 3-month functional status and sICH, and their associations with post-EVT BP metrics were analyzed. RESULTS: A total of 268 post EVT patients were included with a median age of 61&#xa0;years (IQR, 51-69). Mean SBP was 129.67&#xa0;&#xb1;&#xa0;17.17&#xa0;mm Hg, with SBP variability (SD 12.6&#xa0;&#xb1;&#xa0;5.4&#xa0;mm Hg; CV 9.6&#xa0;&#xb1;&#xa0;3.8&#xa0;%), while good functional outcome and sICH occurred in 39.7&#xa0;% and 4.9&#xa0;% of patients, respectively. Multivariate regression showed that higher admission NIHSS&#xa0;(>15) [0.90 (95&#xa0;%CI, [0.86, 0.95], p&#xa0;=&#xa0;0.000)], recanalization status [1.88 (95&#xa0;%CI, [1.43, 2.48], p&#xa0;=&#xa0;0.00)], and SBP-CV&#xa0;&#x2265;&#xa0;10 [0.44 (95&#xa0;%CI, [0.2, 0.94], p&#xa0;=&#xa0;0.036)] was independently associated with poor 3-month functional outcome, while higher admission NIHSS (>15) [0.87 (95&#xa0;%CI, [0.77,0.98], p&#xa0;=&#xa0;0.02)] and diabetes [0.12 (95&#xa0;%CI, [0.03, 0.54], p&#xa0;=&#xa0;0.006)] predicted increased risk of sICH. CONCLUSIONS: The study showed that reduced BP variability during the first 24&#xa0;h post-EVT was associated with better 3-month functional outcomes. A clear association between SBP and sICH risk was not demonstrated.

Endovascular treatment after stroke beyond 24&#xa0;h vs 6-24&#xa0;h: a propensity score-matched cohort study.

BACKGROUND: Endovascular thrombectomy (EVT) is the standard treatment for acute ischemic stroke due to anterior circulation large vessel occlusion (LVO) within 6-24&#xa0;h. However, the safety and feasibility of EVT for anterior circulation strokes beyond 24&#xa0;h remain uncertain. METHODS: We conducted a retrospective cohort study of consecutive patients with anterior circulation LVO who underwent EVT at Changhai Hospital from 2018 to 2023. Patients were stratified into late (6-24&#xa0;h) and very late (>24&#xa0;h) windows. Propensity score matching (PSM) was performed to adjust for baseline imbalances, including age, sex, NIHSS, ASPECTS, occlusion location, perfusion parameters, and vascular risk factors. The primary outcome was functional independence (modified Rankin Scale [mRS]&#xa0;&#x2264;&#xa0;2) at 3&#xa0;months. Secondary outcomes included successful reperfusion (TICI 2b-3) and symptomatic intracranial hemorrhage (sICH). RESULTS: Among 1043 screened patients, 429 patients with anterior circulation LVO were included after exclusions, comprising 373 in the late window and 56 in the very late window. PSM yielded 42 matched pairs. Compared with the late window group, the very late window group showed no statistically significant differences in functional independence (54.8% vs. 57.1%; OR&#xa0;=&#xa0;0.908, 95% CI 0.382-2.153, p&#xa0;=&#xa0;0.830), successful reperfusion (88.1% vs. 92.9%; OR&#xa0;=&#xa0;1.800, 95% CI 0.481-7.096, p&#xa0;=&#xa0;0.460), sICH (2.4% vs. 9.5%; OR&#xa0;=&#xa0;0.232, 95% CI 0.012-1.652, p&#xa0;=&#xa0;0.200), intraprocedural complications (26.2% vs. 19.0%; OR&#xa0;=&#xa0;1.508, 95% CI 0.540-4.362, p&#xa0;=&#xa0;0.440), or postoperative complications (33.3% vs. 35.7%; OR&#xa0;=&#xa0;0.900, 95% CI 0.363-2.219, p&#xa0;=&#xa0;0.820). CONCLUSIONS: In this selected, single-center cohort of anterior circulation LVO patients undergoing EVT, treatment initiated beyond 24&#xa0;h appeared to have comparable effectiveness and safety to treatment initiated within 6-24&#xa0;h. Definitive evidence requires confirmation from adequately powered randomized controlled trials.

Physician-Modified Fenestrated Stent-Grafts Planned Using Three-Dimensional Techniques for Complex Aortic Pathology: A Systematic Review and Meta-Analysis.

BACKGROUND: Complex aortic pathology involving the visceral arteries remains a significant therapeutic challenge. Open repair is associated with considerable perioperative risk, particularly in patients with multiple comorbidities, while standard endovascular aneurysm repair (EVAR) is often not feasible because of inadequate proximal sealing zones. Fenestrated and branched endovascular repair (F/BEVAR) represents an established treatment strategy; however, the use of custom-made devices is limited by manufacturing time and availability. Physician-modified stent grafts (PMSGs) have therefore emerged as a pragmatic alternative. Three-dimensional planning techniques have been increasingly used to facilitate accurate graft modification. The aim of this systematic review and meta-analysis was to evaluate the effectiveness and safety of PMSG procedures planned with three-dimensional techniques. Technical success, target vessel patency, early mortality, endoleak occurrence, and reintervention rates were analyzed. METHODS: A systematic search was conducted in the PubMed/MEDLINE and Embase databases. Studies describing the use of physician-modified fenestrated stent grafts planned with three-dimensional tools were included. Meta-analyses were performed using a random-effects model with restricted maximum likelihood estimation. A logit transformation was used for the analysis of proportions. RESULTS: The analysis included five studies involving 172 patients. The estimated weighted mean follow-up duration was 14.9 months. The overall technical success rate was 92.9% (95% confidence interval [CI]: 84.5-96.9%), with low-to-moderate heterogeneity. Target vessel patency was 96.9% (95% CI: 93.6-98.5%). Early mortality was 5.5% (95% CI: 2.1-13.3%). The incidence of endoleaks was 13.3% (95% CI: 5.8-27.4%), with significant heterogeneity among studies. Reinterventions were reported in 6.6% of patients (95% CI: 2.3-17.5%). CONCLUSION: The results indicate that PMSG procedures planned with three-dimensional techniques are associated with a high rate of technical success and preserved patency of target vessels in patients with complex aortic pathology. The observed variability in endoleak and reintervention rates likely reflects differences in anatomical complexity and patient selection among studies. Further prospective studies are needed to confirm long-term outcomes.

Efficacy and safety of revascularization in patients with chronic limb-threatening ischemia by kidney function.

BACKGROUND: The optimal revascularization strategy for patients with chronic limb-threatening ischemia (CLTI) with chronic kidney disease (CKD) remains unknown. We evaluated whether the efficacy and safety of surgical vs endovascular revascularization differ by kidney function. METHODS: In this post hoc secondary analysis of BEST-CLI trial (NCT02060630), 1,704 patients with CLTI were stratified by baseline estimated glomerular filtration rate (eGFR, mL/min/1.73 m&#xb2;): non-CKD (eGFR &#x2265; 90), mild-moderate CKD (eGFR 45-89), advanced CKD (eGFR < 45 or dialysis). The primary outcome was a composite of major adverse limb events (MALE) or death. We estimated the difference in restricted mean time lost (RMTL, in days) adjusted for inverse probability treatment weights. RESULTS: Surgical revascularization was significantly associated with fewer days with MALE or death in non-CKD (RMTL difference: -127.8 days; 95% CI -176.1, -79.6) and mild-moderate CKD (-63.2 days; 95% CI -104.7, -21.8) but not in advanced CKD (-16.4 days; 95% CI -78.8, 46.0; P interaction = .02). This attenuation reflected a diminishing mortality benefit with more severe CKD (P interaction = .01), whereas the association with fewer days with MALE remained consistent across CKD strata (P interaction = .34). Major adverse cardiovascular events and serious adverse events were more common with more severe CKD but did not differ significantly by treatment. CONCLUSIONS: Surgical vs endovascular revascularization was consistently associated with fewer days with MALE across CKD strata. However, its association with mortality varied by kidney function, attenuating the overall benefit for the composite endpoint of MALE or death. These results support individualized revascularization strategies, but require prospective confirmation. TRIAL REGISTRATION: The BEST CLI trial is registered at ClinicalTrials.gov (NCT02060630).

Aneurysmal subarachnoid hemorrhage care in a middle-income public healthcare system: A real-world neurocritical care cohort.

BACKGROUND AND PURPOSE: Although aneurysm treatment capacity has expanded worldwide, outcomes after aneurysmal subarachnoid hemorrhage (aSAH) remain strongly influenced by neurocritical care (NCC) delivery, referral pathways, and access to specialized treatment. Contemporary data describing real-world aSAH care in resource-limited healthcare systems remain scarce. We aimed to characterize treatment patterns, NCC delivery, complications, and outcomes in a large Brazilian public referral center. METHODS: This retrospective cohort study included consecutive adults with confirmed aSAH admitted between June 2018 and March 2022 to a high-volume Brazilian tertiary referral center. Only patients admitted within five days of symptom onset were included. Demographic, clinical, radiological, treatment, complication, and outcome data were extracted from institutional records. Primary outcomes were in-hospital mortality and 3-month functional outcome assessed by the modified Rankin Scale (mRS). RESULTS: Seventy-four patients were included. Disease severity was high, with 45% presenting WFNS grades 4-5, 73% modified Fisher grade 4 hemorrhage, and 64% hydrocephalus. Endovascular treatment was performed in 73% of cases, and median time from admission to aneurysm treatment was 1&#xa0;day. Despite early treatment capability, only 28% of patients were admitted to an ICU within 48&#xa0;h, while 38% never received ICU care. Delayed cerebral ischemia occurred in 43%, radiologic vasospasm in 58%, ventriculitis in 22%, and infectious complications in 57%. External ventricular drainage was required in 42%, and vasoactive drugs were used in 85%. In-hospital mortality was 42%, and 66% had unfavorable 3-month outcomes (mRS 4-6). CONCLUSIONS: This real-world cohort highlights the substantial neurocritical care burden of aSAH in a middle-income public healthcare system. Despite timely access to definitive aneurysm treatment, patients experienced frequent neurological and systemic complications, emphasizing that contemporary aSAH care extends well beyond aneurysm occlusion.

Aortoesophageal Fistula: Mending the Lethal Connection-A Systematic Review and Meta-Analysis.

BACKGROUND: Aortoesophageal fistula (AEF) is a rare, life-threatening condition with limited high-quality evidence to guide management. METHODS: We conducted a systematic review and meta-analysis of PubMed and Scopus through December 2025, evaluating survival and complication outcomes according to treatment strategy and morphological severity. Patients were categorized into 5 groups: TEVAR alone, staged TEVAR followed by surgery, primary open or hybrid surgery, TEVAR with esophageal stenting, and supportive/palliative care. Outcomes were pooled as proportions with 95% confidence intervals (CIs). RESULTS: A total of 167 reports representing 528 patients were included. Overall 30-day mortality was 31.2% (95% CI 27.0% to 35.7%) and 1-year mortality 41.2% (95% CI 36.2% to 46.4%). Infection occurred in 32.6%, reintervention in 20.2%, and recurrence in 13.2%. Staged TEVAR followed by surgery showed favorable survival (30-day 12.7%, 1-year 26.1%) but high infection (66.7%) and reintervention (43.2%) rates. TEVAR with esophageal stenting had the lowest early mortality (5.0%) but frequent reintervention (54.5%) and 1-year mortality of 33.3%. TEVAR alone demonstrated the lowest 1-year mortality among definitive strategies (25.5%) but notable recurrence (26.9%). Primary open or hybrid surgery carried higher early and late mortality, while supportive/palliative care had the worst outcomes. Morphological severity correlated strongly with mortality, infection, reintervention, and recurrence, with type IV lesions showing particularly poor prognosis. CONCLUSION: Despite contemporary management, AEF carries high early and late mortality. Definitive strategies, particularly staged TEVAR followed by surgery, offer improved survival but increased complications. Morphology-guided, individualized management is recommended.

Prognostic Value of Frailty in Aortic Surgery: A Systematic Review and Meta-Analysis Comparing Frailty Assessment Tools.

BACKGROUND: Frailty is increasingly recognized as an important determinant of outcomes after aortic vascular surgery, but assessment methods vary substantially and the optimal tool for risk stratification remains uncertain. This systematic review and meta-analysis evaluated the prognostic value of preoperative frailty and compared the predictive performance of different frailty instruments in aortic surgery. METHODS: PubMed, Embase, and Cochrane Library were searched from inception to April 27, 2026. Eligible studies included patients undergoing open, endovascular, or hybrid aortic procedures involving abdominal, thoracic, thoracoabdominal, arch, and proximal aortic diseases, including aneurysms and dissections, assessed frailty preoperatively, and reported postoperative outcomes. RESULTS: Thirty studies comprising 419,459 patients were included. Frailty was associated with higher early mortality (odds ratio [OR] 2.20; 95% confidence interval [CI] 1.54-3.14) and late mortality (hazard ratio 2.18; 95% CI 1.64-2.90). Frail patients also had increased risks of major complications (OR 2.52; 95% CI 1.22-5.19), acute kidney injury (OR 1.64; 95% CI 1.34-2.02), and nonhome discharge (OR 5.50; 95% CI 3.05-9.92). Associations were consistent across surgical approaches and aortic segments. Judgment-based or phenotype-like tools yielded higher effect estimates than deficit-accumulation indices, although differences were not statistically significant; among index-based tools, Modified Frailty Index (mFI)-11 outperformed mFI-5. CONCLUSION: Preoperative frailty strongly predicts mortality, morbidity, and loss of functional independence after open, endovascular, and hybrid aortic surgery across different aortic segments and pathologies, including aneurysmal and dissecting aortic disease. Routine frailty assessment may improve risk stratification and perioperative decision-making.

Extending the Treatment Window for Intravenous Thrombolysis in Acute Ischemic Stroke: An Updated Systematic Review and Meta-Analysis.

BACKGROUND AND OBJECTIVES: Intravenous thrombolysis (IVT) is the standard treatment for acute ischemic stroke within 4.5 hours of onset. However, imaging-based selection may extend the treatment window. This systematic review and meta-analysis evaluated the efficacy and safety of IVT administered beyond 4.5 hours after stroke onset or last known well (LKW) in patients selected based on imaging findings. METHODS: A comprehensive search of PubMed, Scopus, and Cochrane Library was performed to identify randomized controlled trials comparing IVT with alteplase or tenecteplase (TNK) administered >4.5 hours after stroke onset/LKW vs standard care. Primary outcomes were 3-month excellent (modified Rankin Scale [mRS] 0-1) functional outcome and symptomatic intracranial hemorrhage (sICH). Secondary outcomes included good (mRS 0-2) functional outcome, recanalization, and 3-month mortality. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using random-effects models. Subgroup analysis assessed differences between alteplase and TNK. RESULTS: Fourteen studies involving 4,944 patients were included. The mean age was 69.8 years, 58.2% were male, the median National Institutes of Health Stroke Scale score was 9, and 12.3% received preplanned endovascular thrombectomy (EVT). A total of 2,492 patients received IVT in an extended time window (4.5-24 hours). Compared with standard care, extended IVT was associated with higher odds of achieving an excellent functional outcome (OR: 1.43 [95% CI 1.25-1.63]), a good functional outcome (OR: 1.25 [95% CI 1.11-1.40]), and recanalization (OR: 3.28 [95% CI 2.09-5.16]). There was no difference in 3-month mortality (OR: 1.21 [95% CI 0.95-1.53]). However, IVT increased the risk of sICH (OR: 2.51 [95% CI 1.47-4.28]). Sensitivity analysis excluding patients who received EVT showed no impact on the outcomes. TNK exhibited similar efficacy to alteplase but showed potentially lower odds of sICH (OR: 1.96, 95% CI 1.06-3.64) compared with alteplase (OR: 5.29, 95% CI 1.80-15.57); however, the subgroup difference was not significant (p = 0.11). DISCUSSION: Among patients selected based on imaging, 4.5-24 hours after stroke onset/LKW, IVT improves outcomes despite an increased risk of sICH. TNK showed similar efficacy to alteplase, with a possible lower risk of sICH; however, direct comparisons in future trials are needed.

Effect of Baseline ASPECTS on Tenecteplase Efficacy Before Thrombectomy in Acute Large-Vessel Occlusion Stroke: A Post Hoc Analysis of the BRIDGE-TNK Randomized Trial.

BACKGROUND AND OBJECTIVES: The impact of ischemic extent on the efficacy and safety of intravenous thrombolysis before thrombectomy remains uncertain. The aim of this study was to evaluate whether the baseline ischemic extent, measured by the Alberta Stroke Program Early Computed Tomography Score (ASPECTS), modifies outcomes of intravenous tenecteplase administered before endovascular thrombectomy. METHODS: This was a post hoc analysis of the BRIDGE-TNK (thrombectomy with vs without rhTNK-tPA in stroke) trial, conducted across China from May 2022 to September 2024. We compared the efficacy and safety of intravenous tenecteplase plus thrombectomy vs thrombectomy alone in acute large-vessel occlusion stroke patients within 4.5 hours of last known well, stratified by baseline ASPECTS (<8 vs 8-10). The outcomes included 90-day functional independence (modified Rankin Scale score of 0-2), 48-hour symptomatic intracranial hemorrhage (sICH), and 90-day mortality. Regression models incorporating a treatment-by-ASPECTS interaction term were used for analysis. RESULTS: Among 550 patients, 241 (43.8%) had ASPECTS <8 (median [interquartile range, IQR] age, 69 [61-77] years; 56.4% male) and 309 had ASPECTS 8-10 (median [IQR] age, 70 [61-77] years; 59.5% male). The rate of functional independence was significantly higher in the tenecteplase plus thrombectomy group than in the thrombectomy-alone group in the ASPECTS <8 subgroup (adjusted risk ratio [aRR], 1.67; 95% CI 1.18-2.35), but not in the ASPECTS 8-10 subgroup (aRR, 0.99; 95% CI 0.84-1.17; pinteraction = 0.007). Rates of sICH did not differ significantly between treatment groups in either ASPECTS subgroups (ASPECTS <8: 10.0% vs 11.2%; ASPECTS 8-10: 7.5% vs 2.8%; pinteraction = 0.11). Ninety-day mortality was comparable between treatment groups in the ASPECTS <8 subgroup, but numerically higher with tenecteplase plus thrombectomy in the ASPECTS 8-10 subgroup (aRR = 1.89, 95% CI 0.99-3.61, pinteraction = 0.04). DISCUSSION: In this exploratory post hoc analysis, a signal of benefit was observed in patients with ASPECTS <8 who received intravenous tenecteplase before thrombectomy, whereas no functional improvement and possible safety concerns were seen in those with ASPECTS 8-10. Prospective confirmation in randomized trials is required before practice change. TRIAL REGISTRATION INFORMATION: ClinicalTrials.gov; Unique identifier: NCT04733742.

Efficacy of high-intensity laser therapy versus ultrasound therapy in patients with knee osteoarthritis: a randomized controlled trial.

PURPOSE: High-intensity laser therapy (HILT) and ultrasound (US) are widely used for knee osteoarthritis (KOA), but comparative efficacy data remain scarce. This study compared HILT and US as exercise adjuncts in patients with KOA. METHODS: In this single-center, assessor-blinded RCT, 66 adults with KOA were randomized 1:1 to HILT or US twice weekly for 6&#xa0;weeks as exercise adjuncts. The primary outcome was WOMAC total score change from baseline to 12&#xa0;weeks post-treatment (minimum important change [MIC]&#x2009;=&#x2009;10 points, applied as an approximation). Secondary outcomes included VAS, OKS, KOOS, and EQ-5D-5L. RESULTS: In ITT analysis (N&#x2009;=&#x2009;66), the HILT group achieved a mean WOMAC reduction of 40.0 vs 8.2 points (adjusted between-group difference: -27.7 points, 95% CI:&#x2009;-&#x2009;39.0 to&#x2009;-&#x2009;16.5; p&#x2009;<&#x2009;0.001, partial &#x3b7;2&#x2009;=&#x2009;0.277). At 12&#xa0;weeks post-treatment, greater improvements across all secondary outcomes were observed in exploratory analyses (p&#x2009;&#x2264;&#x2009;0.012). Furthermore, HILT maintained therapeutic effects up to 12&#xa0;weeks post-treatment, whereas the US group experienced a gradual loss of post-treatment gains. CONCLUSION: HILT combined with exercise produced greater short-term improvements in WOMAC total score than US in patients with KOA, with exploratory findings suggesting consistent benefits in pain, function, and quality of life, and with benefits maintained up to 12&#xa0;weeks after the last treatment session.

Cost-Effectiveness and the Economics of Genomic Testing and Molecularly Matched Therapies.

Cost-effectiveness analysis of precision oncology can help guide value-driven care. Next-generation sequencing is increasingly cost-efficient over single gene testing because diagnostic algorithms require multiple individual gene tests to determine biomarker status. Matched targeted therapy is often not cost-effective due to the high cost associated with drug treatment. However, genomic profiling can promote cost-effective care by identifying patients who are unlikely to benefit from therapy. Additional applications of genomic profiling such as universal testing for hereditary cancer syndromes and germline testing in patients with cancer may represent cost-effective approaches compared with traditional history-based diagnostic methods.

Insulin, Semaglutide and Dapagliflozin in Adults With Type 1 Diabetes: Design and Methods of Triple Therapy for Type 1 Diabetes (TTT1)-An International Phase 3 Clinical Trial.

AIMS: Attaining target glycaemia can be a challenge in Type 1 Diabetes (T1D) due to insulin-induced weight gain. Adjunct therapy with modern glucose-lowering agents developed for type 2 diabetes (T2D) has great potential but may be insufficiently efficacious and carries risks of hypoglycaemia and ketosis. We designed the first Phase 3 clinical trial to assess the efficacy and safety of adding a Glucagon-Like Peptide 1 receptor agonist (GLP-1RA) and a Sodium-Glucose Co-transporter (SGLT2) Inhibitor to insulin therapy in overweight and obese adults with T1D and glycaemia above target (HbA1c 7.5%-11.0% inclusive) (NCT03899402). MATERIALS AND METHODS: In Period 1, participants are randomized 2:1 (open label) for 26&#x2009;weeks to semaglutide and insulin (uptitrated to 1.0&#x2009;mg weekly) or standard insulin therapy. In Period 2, those randomized to semaglutide and insulin in Period 1 are further randomized (double-blind) for 26&#x2009;weeks to dapagliflozin (10&#x2009;mg daily) or placebo, in addition to semaglutide. The primary objective is to compare change in HbA1c on 'triple therapy' (dapagliflozin, semaglutide and insulin) with 'dual therapy' (placebo, semaglutide and insulin). Secondary objectives include comparisons of triple therapy with standard insulin therapy and dual therapy (semaglutide and insulin) with standard insulin therapy. Safety outcomes include hypoglycaemia and ketosis. A sample size recalculation during the trial based on analysis of masked data revised the original recruitment target from 114 to 82 participants. CONCLUSION: The TTT1 trial will provide clinically useful information on combination adjunct therapy in the treatment of T1D.

Understanding FDA's reasons for nonapproval: A systematic review of complete response letters in cell and gene therapy.

BACKGROUND AIMS: Cell and gene therapy products face unique regulatory challenges due to their biological complexity and the stringent expectations for manufacturing control, analytical testing, and clinical assessment. As the pipeline grows, understanding the drivers of FDA non&#x2011;approval is increasingly important for improving first&#x2011;cycle success and reducing development delays. In this study, we aimed to characterize the frequency and impact of refuse&#x2011;to&#x2011;file actions, major amendments, and complete response letters issued for biologics licensing applications; and to identify recurring patterns of deficiencies contributing to delayed approval. METHODS: Publicly available documents were extracted from the FDA website. Data from each approved cell and gene therapy product's regulatory history-including complete responses, major amendments, inspection timing, and cited deficiencies-were compiled and categorized across clinical, quality, and labeling domains. RESULTS: Analysis showed that informational deficiencies were common across modalities. Major amendments occurred in roughly half of applications, and complete responses had the most significant impact. Quality deficiencies appeared in all complete responses and were the predominant barrier, while clinical and labeling issues were less frequent but meaningful when present. CONCLUSION: Overall, these findings highlight the need for proactive FDA engagement, comprehensive readiness, and early inspection preparation to reduce regulatory risk and improve first cycle approval outcomes.

Effects of Cognitive Behavioral Couple Therapy With Integrated Mindfulness on Mindful Attention, Depressive Symptoms, and Dyadic Adjustment in Low-Income Couples: A Pilot Randomized Clinical Trial.

Psychosocial distress can exacerbate marital conflict, maladjustment, and mental health vulnerability. This pilot randomized clinical trial examined cognitive-behavioral couple therapy (CBCT) integrated with mindfulness in low-income Brazilian couples (per-capita household income up to one minimum wage). Thirty-four participants (17 heterosexual couples) were randomized (independent computer-generated sequence) to an experimental (n&#x2009;=&#x2009;16) or waitlist control group (n&#x2009;=&#x2009;18). We assessed dyadic adjustment, mindful attention, marital social skills, and depressive symptoms (R-DAS, MAAS, IHSC, BDI-II) at baseline, post-treatment, and 3-month follow-up. The intervention was eight 80-min conjoint sessions plus daily home exercises. Time&#x2009;&#xd7;&#x2009;group effects favored the experimental group for dyadic adjustment, mindful attention, and depressive symptoms (all p&#x2009;<&#x2009;0.001,&#x2009;=&#x2009;0.20-0.37), but not marital social skills (p&#x2009;=&#x2009;0.14). Because two outcomes differed at baseline, effects were confirmed with baseline- and dependence-adjusted sensitivity analyses. These findings provide preliminary evidence that CBCT with mindfulness may benefit disadvantaged couples.
