ABSTRACT
AIM: To evaluate the prognostic value of GDF-15 in relation the development of bleeding and events in stable CAD patients, receiving combined antithrombotic therapy. MATERIALS AND METHODS: The data was obtained from the prospective registry REGATA, 343 CAD patients (249 males), median age 68 [IQR 62; 75] years) were enrolled. Patients with sinus rhythm and concomitant PAD received acetylsalicylic acid in combination with rivaroxaban 2.5 mg bid (31.8%) or clopidogrel (24.8%). Other 43.4% with concomitant atrial fibrillation (AF) received direct oral anticoagulants in combination with antiplatelet therapy after elective percutaneous coronary interventions. Median follow-up was 12 months [IQR 9.0; 18.0]. The safety end point was major and clinically relevant bleedings (type 2-5) according to the BARC classification. Plasma samples for GDF-15 identification were taken at the inclusion and analyzed using ELISA assay. RESULTS: Frequency of BARC 2-5 bleedings was 16% (BARC 2 - 46; BARC 3 - 9; BARC 4-5 - 0), median GDF-15 level was 1185.0 pg/ml [850.0; 1680.0]. In patients with AF and concomitant MFA, the level of GDF-15 was significantly higher than in the subgroups of patients with only AF or MFA (p=0.0022). According to the quintile analysis, GDF-15 values in the top three quintiles of distribution (cut-off value >943 pg/ml) were associated with higher frequency of bleeding events: 23.2% versus 5.1%; p=0.0001. The multivariable logistic regression model demonstrated that bleeding events were independently associated with GDF-15 level>943 pg/ml (OR 2.65, 95% CI 1.11-6.30; p=0.0275), AF (OR 2.61, 95% CI 1.41-4.83; p=0.0023) and chronic kidney disease (OR 1.92, 95% CI 1.03-3.60; p=0.0401). Clinical factors determining the risk of bleeding events also determined a GDF-15 elevation. CONCLUSION: Assessment of GDF-15 level may improve bleeding risk stratification in CAD patients with concomitant AF and/or PAD receiving combined antithrombotic therapy.

Bleeding within the pleural space may result in persistent clot formation called retained hemothorax (RH). RH is prone to organization, which compromises effective drainage, leading to lung restriction and dyspnea. Intrapleural fibrinolytic therapy is used to clear the persistent organizing clot in lieu of surgery, but fibrinolysin selection, delivery strategies, and dosing have yet to be identified. We used a recently established rabbit model of RH to test whether intrapleural delivery of single-chain urokinase (scuPA) can most effectively clear RH. scuPA, or single-chain tissue plasminogen activator (sctPA), was delivered via thoracostomy tube on day 7 as either one or two doses 8 h apart. Pleural clot dissolution was assessed using transthoracic ultrasonography, chest computed tomography, two-dimensional and clot displacement measurements, and gross analysis. Two doses of scuPA (1 mg/kg) were more effective than a bolus dose of 2 mg/kg in resolving RH and facilitating drainage of pleural fluids (PF). Red blood cell counts in the PF of scuPA, or sctPA-treated rabbits were comparable, and no gross intrapleural hemorrhage was observed. Both fibrinolysins were equally effective in clearing clots and promoting pleural drainage. Biomarkers of inflammation and organization were likewise comparable in PF from both groups. The findings suggest that single-agent therapy may be effective in clearing RH; however, the clinical advantage of intrapleural scuPA remains to be established by future clinical trials.

This review explores the clinical presentation of lower extremity DVT and pulmonary embolism (PE), treatment strategies, and outcomes for venous thromboembolism (VTE) in the pediatric population. Traditional therapy for pediatric VTE was anticoagulation alone with thrombolysis and surgery reserved only in life or limb-threatening cases. Catheter-directed thrombolysis (CDT), pharmacomechanical thrombectomy (PMT) and mechanical thrombectomy (MT) have emerged as effective and safe treatment options for VTE management. Although most data are from adult studies, early pediatric studies suggest that these interventional procedures can be effective in children. The significant clinical impact of post-thrombotic syndrome (PTS) is also discussed, as PTS can lead to lifelong physical symptoms and psychosocial damage.

The use of antithrombotic agents is increasing in infants, children and adolescents. The more recent routine inclusion of children in FDA-monitored clinical trials has propelled the rapid accumulation of safety and efficacy data on these agents in pediatric patients. Antithrombotic agents in current use include indirect or antithrombin-dependent anticoagulants, intravenous direct thrombin inhibitors, direct oral anticoagulants (DOACs) targeting thrombin or factor Xa, antiplatelet agents and thrombolytic therapies. Each class of antithrombotic agent has distinct mechanisms of action, clearance routes, half-lives, safety and dosing. Anticoagulant efficacy is dependent upon the specific clinical indication and stability of the pediatric patient. Duration of anticoagulant course is also dependent upon the clinical indication as well as rate of thrombus resolution. This manuscript reviews the mechanism of action, route of administration, route of clearance and plasma half-life for the antithrombotic agents in current use in children. Use of anticoagulation in the context of thrombolytic therapy is discussed.

BACKGROUND: The optimal treatment for acute minor ischemic stroke is still undefined. and options include dual antiplatelet treatment (DAPT), intravenous thrombolysis (IVT), or their combination. We aimed to investigate benefits and risks of combining IVT and DAPT versus DAPT alone in patients with MIS. METHODS AND RESULTS: This is a prespecified propensity score-matched analysis from a prospective multicentric real-world study (READAPT [Real-Life Study on Short-Term Dual Antiplatelet Treatment in Patients With Ischemic Stroke or Transient Ischemic Attack]). We included patients with MIS (National Institutes of Health Stroke Scale score at admission ≤5), without prestroke disability (modified Rankin scale [mRS] score ≤2). The primary outcomes were 90-day mRS score of 0 to 2 and ordinal mRS distribution. The secondary outcomes included 90-day risk of stroke and other vascular events and 24-hour early neurological improvement or deterioration (≥2-point National Institutes of Health Stroke Scale score decrease or increase from the baseline, respectively). From 1373 patients with MIS, 240 patients treated with IVT plus DAPT were matched with 427 patients treated with DAPT alone. At 90 days, IVT plus DAPT versus DAPT alone showed similar frequency of mRS 0 to 2 (risk difference, 2.3% [95% CI -2.0% to 6.7%]; P=0.295; risk ratio, 1.03 [95% CI 0.98-1.08]; P=0.312) but more favorable ordinal mRS scores distribution (odds ratio, 0.57 [95% CI 0.41-0.79]; P<0.001). Compared with patients treated with DAPT alone, those combining IVT and DAPT had higher 24-hour early neurological improvement (risk difference, 20.9% [95% CI 13.1%-28.6%]; risk ratio, 1.59 [95% CI 1.34-1.89]; both P<0.001) and lower 90-day risk of stroke and other vascular events (hazard ratio, 0.27 [95% CI 0.08-0.90]; P=0.034). There were no differences in safety outcomes. CONCLUSIONS: According to findings from this observational study, patients with MIS may benefit in terms of better functional outcome and lower risk of recurrent events from combining IVT and DAPT versus DAPT alone without safety concerns.

A 48-year-old man with a history of mitral valve replacement (MVR) in March 2019 for rheumatic heart disease (RHD) and ischemic stroke in August 2019 presented with a history of sudden onset angina of 6 hours duration. He admits to defaulting oral anticoagulant (OAC) intake for the last 50 days. On arrival, he had atrial fibrillation with hemodynamic instability [blood pressure (BP) 70/40 mm Hg, saturation of peripheral oxygen (SpO2) 80% at room air and heart rate approx 140/minute], which was managed with intravenous diltiazem and hemodynamic stability achieved (BP 116/72 mm Hg, heart rate 86/minute). Urgent transthoracic echocardiogram (TTE) and fluoroscopy confirmed obstructive prosthetic mitral valve thrombosis. Though available recommendations suggest surgical intervention for the left-sided valve involvement in a stable patient, in view of the nonavailability of a surgical facility, the patient was thrombolyzed with Alteplase, a recombinant tissue plasminogen activator (rtPA). Since the patient was stable, a "long fibrinolytic protocol" of Alteplase 10 mg bolus, 50 mg during the 1st hour, and 20 mg each during the 2nd and 3rd hour (total of 100 mg) was given. Subsequent TTE revealed a mean gradient of 5 mm Hg, and cine fluoroscopy showed improved mitral valve motion, thereby indicating successful thrombolysis. The patient felt symptomatically relieved within 6 hours and is presently on OAC therapy with strict drug compliance.

Background: Alteplase intravenous thrombolysis is effective for treating acute ischemic stroke (AIS) within 4.5 h. Nevertheless, the prognosis remains poor for some patients.Objective: To investigate the risk factors for poor prognosis in patients undergoing intravenous thrombolysis with alteplase following AIS based on propensity score matching and to develop a predictive model.Result: Multivariate logistic regression analysis showed that baseline blood glucose (OR = 1.20, 95%CI, 1.03-1.39), baseline NIH Stroke Scale score (OR = 1.23, 95%CI, 1.12-1.35), and hyperlipidemia (OR = 6.60, 95%CI 1.74-25.00) were risk factors for poor prognosis in patients with AIS undergoing alteplase intravenous thrombolysis. Using these factors, a nomogram model was constructed for predicting patient prognosis at 3 months. The areas under the receiver operating characteristic curve (AUCs) of the training and validation groups were 0.792 (95CI% 0.715-0.870) and 0.885 (95CI% 0.798-0.972), respectively, showing good differentiation. The Hosmer Lemeshow goodness-of-fit test showed that the model had good fit. The calibration curve fitted well with the ideal curve, and the decision curve analysis curve showed that the model had good clinical applicability when the threshold probability was between 10%-80%.Conclusion: The established nomogram could successfully predict the 3-month prognosis of patients with AIS after undergoing alteplase intravenous thrombolysis. The model thus has clinical application value.

According to the importance of time in treatment of thrombosis disorders, faster than current treatments are required. For the first time, this research discloses a novel strategy for rapid dissolution of blood clots by encapsulation of a fibrinolytic (Reteplase) into a Thrombin sensitive shell formed by polymerization of acrylamide monomers and bisacryloylated peptide as crosslinker. Degradability of the peptide units in exposure to Thrombin, creates the Thrombin-sensitive Reteplase nanocapsules (TSRNPs) as a triggered release system. Accelerated thrombolysis was achieved by combining three approaches including: deep penetration of TSRNPs into the blood clots, changing the clot dissolution mechanism by altering the distribution pattern of TSRNPs to 3D intra-clot distribution (based on the distributed intra-clot thrombolysis (DIT) model) instead of peripheral and unidirectional distribution of unencapsulated fibrinolytics and, enzyme-stimulated release of the fibrinolytic. Ex-vivo study was carried out by an occluded tube model that mimics in-vivo brain stroke as an emergency situation where faster treatment in short time is a golden key. In in vivo, efficacy of the developed formulation was confirmed by PET scan and laser Doppler flowmetry (LDF). As the most important achievements, 40.0 ± 0.7 (n = 3) % and 37.0 ± 0.4 (n = 3) % reduction in the thrombolysis time (faster reperfusion) were observed by ex-vivo and in-vivo experiments, respectively. Higher blood flow and larger digestion mass of clot at similar times in comparison to non-encapsulated Reteplase were observed that means more effective thrombolysis by the developed strategy.

BACKGROUND: Complicated pleural infection comprises of complex effusions and empyema. When tube thoracostomy is ineffective, treatment options include surgical drainage, deloculation and decortication or intrapleural fibrinolysis. We performed a systematic review and meta-analysis to examine which technique is superior in treating complicated pleural infections. METHODS: PubMed, MEDLINE and EMBASE databases were searched for studies published between January 2000 to July 2023 comparing surgery and intrapleural fibrinolysis for treatment of complicated pleural infection. The primary outcome was treatment success. Secondary outcomes included hospital length of stay, chest drain duration and in-hospital mortality. RESULTS: Surgical management of complicated pleural infections was more likely to be successful than intrapleural fibrinolysis (RR 1.18; 95% CI 1.02, 1.38). Surgical intervention group benefited from statistically significant shorter hospital length of stay (MD: 3.85; 95% CI 1.09, 6.62) and chest drain duration (MD: 3.42; 95% CI 1.36, 5.48). There was no observed difference between in-hospital mortality (RR: 1.00; 95% CI 0.99, 1.02). CONCLUSION: Surgical management of complicated pleural infections results in increased likelihood of treatment success, shorter chest drain duration and hospital length of stay in the adult population compared with intrapleural fibrinolysis. In-hospital mortality did not differ. Large cohort and randomized research need to be conducted to confirm these findings.

Background The combination of intravenous thrombolysis (IVT) with mechanical thrombectomy (MT) may have clinical benefits for patients with medium vessel occlusion. Purpose To examine whether MT combined with IVT is associated with different outcomes than MT alone in patients with acute ischemic stroke (AIS) and medium vessel occlusion. Materials and Methods This retrospective study included consecutive adult patients with AIS and medium vessel occlusion treated with MT or MT with IVT at 37 academic centers in North America, Asia, and Europe. Data were collected from September 2017 to July 2021. Propensity score matching was performed to reduce confounding. Univariable and multivariable logistic regression analyses were performed to test the association between the addition of IVT treatment and different functional and safety outcomes. Results After propensity score matching, 670 patients (median age, 75 years [IQR, 64-82 years]; 356 female) were included in the analysis; 335 underwent MT alone and 335 underwent MT with IVT. Median onset to puncture (350 vs 210 minutes, P < .001) and onset to recanalization (397 vs 273 minutes, P < .001) times were higher in the MT group than the MT with IVT group, respectively. In the univariable regression analysis, the addition of IVT was associated with higher odds of a modified Rankin Scale (mRS) score 0-2 (odds ratio [OR], 1.44; 95% CI: 1.06, 1.96; P = .019); however, this association was not observed in the multivariable analysis (OR, 1.37; 95% CI: 0.99, 1.89; P = .054). In the multivariable analysis, the addition of IVT also showed no evidence of an association with the odds of first-pass effect (OR, 1.27; 95% CI: 0.9, 1.79; P = .17), Thrombolysis in Cerebral Infarction grades 2b-3 (OR, 1.64; 95% CI: 0.99, 2.73; P = .055), mRS scores 0-1 (OR, 1.27; 95% CI: 0.91, 1.76; P = .16), mortality (OR, 0.78; 95% CI: 0.49, 1.24; P = .29), or intracranial hemorrhage (OR, 1.25; 95% CI: 0.88, 1.76; P = .21). Conclusion Adjunctive IVT may not provide benefit to MT in patients with AIS caused by distal and medium vessel occlusion. © RSNA, 2024 Supplemental material is available for this article.

OBJECTIVE: To compare the effectiveness and safety of the use of non-immunogenic staphylokinase (NS) and alteplase (AP) for intravenous thrombolysis (IT) for ischemic stroke (IS) in real clinical practice at a regional vascular center. MATERIAL AND METHODS: Data from 100 patients with IS who received IT with NS and 100 patients who received IT with AP for the period 2022-2023 were analyzed. The groups were comparable on sociodemographic parameters, cardiovascular risk factors and diseases, and stroke characteristics. RESULTS: Door-to-needle time was 17 (13-22) min in the NS group and 38 (33-42) min in the AP group (p<0.001). During control neuroimaging, a cerebral infarction was detected in 46% of patients in the NS group and 61% of patients in the AP group (OR 0.479 [0.263; 0.875], p=0.035). When performing IT with NS, an NIHSS score of 0 points (no neurological deficit) was observed twice as often (OR 2.202 [1.079; 4.504], p=0.023). The incidence of hemorrhagic transformation, including symptomatic, as well as hospital mortality did not differ. CONCLUSION: IT with NS is associated with a lower probability of cerebral infarction and greater positive dynamics of the neurological status in comparison with the use of AP already within the first stage of treatment and rehabilitation.

Intravenous thrombolysis is the standard treatment for acute ischemic stroke. We here report the cases of thrombolysis alert in the private sector in Morocco We conducted a prospective study of all patients with neurological deficit of sudden onset occurred within the first 12 hours admitted to the Emergency Department of the Al Badie international private clinic from January 2022 to September 2023. Epidemiological, clinical and etiological characteristics as well as data on outpatient and inpatient delays were collected. Sixty patients were included in the study. The average admission delay was 198.36 ± 79.23 minutes. The mean NIHSS (National Institutes of Health Stroke Scale) score was 10.41 ± 4.97. The average time for imaging was 26.68 ± 9.63 minutes. Ischaemic stroke was the most common diagnosis (85%), followed by "stroke mimics" (11.6%). Thirteen patients underwent thrombolysis with tenecteplase. The mean time from admission to the initiation of thrombolysis was 107.15 ± 24.48 minutes. Follow-up imaging at 24 hours post thrombolysis revealed symptomatic haemorrhagic transformation in 3 patients. Six patients were transferred to the Hassan II University Hospital for thrombolysis and/or mechanical thrombectomy. After 3 months, 4 patients were autonomous (Rankin score changed between 0 and 2). Our experience shows that it is imperative to reduce outpatient and inpatient delays in treatment in order to increase the proportion of patients treated with thrombolysis.

BACKGROUND: Management of complicated pleural infections (CPIs) had historically been surgical; however, following the publication of the second multicenter intrapleural sepsis trial (MIST-2), combination tissue plasminogen (tPA) and dornase (DNase) offers a less invasive and effective treatment. Our aim was to assess the quality of life (QOL) and functional ability of patients' recovery from a CPI managed with either intrapleural fibrinolytic therapy (IPFT) or surgery. METHODS: We identified 565 patients managed for a CPI between January 1, 2013 and March 31, 2018. There were 460 patients eligible for contact, attempted through 2 phone calls and one mailer. Two questionnaires were administered: the Short Form 36-Item Health Survey (SF-36) and a functional ability questionnaire. RESULTS: Contact was made in 35% (159/460) of patients, and 57% (90/159) completed the survey. Patients had lower QOL scores compared to average US citizens; those managed with surgery had higher scores in physical functioning (surgery: 80, IPFT: 70, P=0.040) but lower pain scores (surgery: 58, IPFT: 68, P=0.045). Of 52 patients who returned to work, 48% (25) reported an impact on their work effectiveness during recovery, similarly between management strategies (IPFT: 50%, 13/26 vs. surgery: 46%, 12/26; P=0.781). CONCLUSION: Patients with a CPI had a lower QOL compared with average US citizens. Surgically managed patients reported improved physical functioning but worse pain compared with patients managed with IPFT. Patients returned to work within 4 weeks of discharge, and nearly half reported their ability to work effectively was impacted by their recovery. With further research into recovery timelines, patients may be appropriately counselled for expectations.

OBJECTIVES: Although intrapleural administration of fibrinolytics is an important treatment option for the management of empyema, the addition of fibrinolytics failed to reduce the need for surgery and mortality in previous randomized controlled trials. This study aimed to investigate the effects of administrating fibrinolytics in the early phase (within 3 days of chest tube insertion) of empyema compared with late administration or no administration. METHODS: We used the Japanese Diagnosis Procedure Combination Inpatient Database to identify patients aged ≥16 years who were hospitalized and underwent chest tube drainage for empyema. A 1:2 propensity score matching and stabilized inverse probability of treatment weighting were conducted. RESULTS: Among the 16 265 eligible patients, 3082 and 13 183 patients were categorized into the early and control group, respectively. The proportion of patients who underwent surgery was significantly lower in the early fibrinolytics group than in the control group; the odds ratio (95% confidence interval) was 0.69 (0.54-0.88) in the propensity score matching (P = 0.003) and 0.64 (0.50-0.80) in the stabilized inverse probability of treatment weighting analysis (P < 0.001). All-cause 30-day in-hospital mortality, length of hospital stay, duration of chest tube drainage, and total hospitalization costs were also more favourable in the early fibrinolytics group. CONCLUSIONS: The early administration of fibrinolytics may reduce the need for surgery and death in adult patients with empyema.

BACKGROUND: The percentage of elderly trauma patients under anticoagulation and antiplatelet agents has been rising lately. As newer agents are introduced, each comes with its own advantages and precautions. Our study covered elderly patients admitted to the ED with maxillofacial trauma while on anticoagulation (AC) or antiplatelet therapy (APT). We aimed to investigate the demographic characteristics, causes, and types of maxillofacial trauma, along with concomitant injuries, duration of hospitalisation, haemorrhagic complications, and the overall costs of care in the emergency department (ED). METHODS: Data were gathered from the ED of Bern University Hospital. In this retrospective analysis, patients over 65 of age were included, who presented at our ED with maxillofacial trauma between 2013 and 2019 while undergoing treatment with therapeutic AC/APT. RESULTS: The study involved 188 patients with a median age of 81 years (IQR: 81 [74; 87]), of whom 55.3% (n=104) were male. More than half (54.8%, n=103) were aged 80 years or older. Cardiovascular diseases were present in 69.7% (n=131) of the patients, with the most common indications for AC/APT use being previous thromboembolic events (41.5%, n=78) and atrial fibrillation (25.5%, n=48). The predominant cause of facial injury was falls, accounting for 83.5% (n=157) of cases, followed by bicycle accidents (6.9%, n=13) and road-traffic accidents (5.3%, n=10). The most common primary injuries were fractures of the orbital floor and/or medial/lateral wall (60.1%, n=113), zygomatic bone (30.3%, n=57), followed by isolated orbital floor fractures (23.4%, n=44) and nasal bone fractures (19.1%, n=36). Fractures of the mandible occurred in 14.9% (n=28). Facial hematomas occurred in 68.6% of patients (129 cases), primarily in the midface area. Relevant facial bleeding complications were intracerebral haemorrhage being the most frequent (28.2%, n=53), followed by epistaxis (12.2%, n=23) and retrobulbar/intraorbital hematoma (9%, n=17). Sixteen patients (8.5%) experienced heavy bleeding that required emergency treatment. The in-hospital mortality rate was 2.1% (4 cases). CONCLUSIONS: This study indicates that falls are the leading cause of maxillofacial trauma in the elderly, with the most common diagnoses being orbital, zygomatic, and nasal fractures. Haemorrhagic complications primarily involve facial hematomas, especially in the middle third of the face, with intracerebral haemorrhage being the second most frequent. Surgical intervention for bleeding was required in 8.5% of cases. Given the aging population, it is essential to improve prevention strategies and update safety protocols, particularly for patients on anticoagulant/antiplatelet therapy (AC/APT). This can ensure rapid diagnostic imaging and prompt treatment in emergencies.

OBJECTIVES: After introducing a team simulation training programme at our hospital, we saw a reduction in door-to-needle times (DNT) for stroke thrombolysis but persisting variability prompting further investigation. Our objective is to examine this gap through assessing: (1) whether there is an association between DNT and the clinical experience of neurology registrars and (2) whether experience influences the benefits from attending simulation. DESIGN: Prospective cohort study. SETTING AND PARTICIPANTS: Patients treated with intravenous thrombolysis between January 2016 and 2020 at a Norwegian stroke centre. PRIMARY AND SECONDARY OUTCOME MEASURES: Using DNT and prior intravenous thrombolysis administrations (case-based definition of clinical experience) as continuous variables, a mixed effects linear regression model was performed to examine the association between clinical experience, DNT and simulation attendance. For dichotomised analyses, neurology registrars with 15 or more prior treatments were defined as experienced. RESULTS: A total of 532 patients treated by 36 neurology registrars from January 2016 to 2020 were included. There was a linear association between clinical experience and DNT (test for non-linearity p=0.479). Each prior intravenous thrombolysis administration was associated with a significant 1.1% decrease in DNT in the adjusted analysis (ΔDNT -1.1%; 95% CI, -2.2% to -0.0%; p=0.048). The interaction between effects of clinical experience and simulation on DNT was not statistically significant (p=0.150). In the dichotomised analysis, experienced registrars had similar gains from attending simulation sessions (mean DNT from 18.5 min to 13.5 min) compared with less experienced registrars (mean DNT from 22.4 min to 17.4 min). CONCLUSIONS: Less experienced registrars had longer DNT in stroke thrombolysis. Attending team simulation training was associated with similar improvements for experienced and inexperienced neurology registrars. We suggest a focus on high-quality onboarding programmes to close the experience-related quality gap. Our findings suggest that both inexperienced and experienced neurology registrars might benefit from team simulation training for stroke thrombolysis.

OBJECTIVES: This study is to establish a nomination graph model for individualised early prediction of the 3-month prognosis of patients who had an acute ischaemic stroke (AIS) receiving intravenous thrombolysis with recombinant tissue plasminogen activator. DESIGN: For the period from January 2016 through August 2022, 991 patients who had an acute stroke eligible for intravenous thrombolysis were included in the retrospective analysis study. The study was based on multifactor logistic regression. PARTICIPANTS: Patients who received treatment from January 2016 to February 2021 were included in the training cohort, and those who received treatment from March 2021 to August 2022 were included in the testing cohort. INTERVENTIONS: Each patient received intravenous thrombolysis within 4.5 hours of onset, with treatment doses divided into standard doses (0.9 mg/kg). PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome measure was a 3-month adverse outcome (modified Rankin Scale 3-6). RESULTS: The National Institutes of Health Stroke Scale Score after thrombolysis (OR=1.18; 95% CI: 1.04 to 1.36; p = 0.015), door-to-needle time (OR=1.01; 95% CI: 1.00 to 1.02; p = 0.003), baseline blood glucose (OR=1.08; 95% CI: 1.00 to 1.16; p=0.042), blood homocysteine (OR=7.14; 95% CI: 4.12 to 12.71; p<0.001), monocytes (OR=0.05; 95% CI: 0.01 to 0.043; p=0.005) and monocytes/high-density lipoprotein (OR=62.93; 95% CI: 16.51 to 283.08; p<0.001) were independent predictors of adverse outcomes 3 months after intravenous thrombolysis, and the above six factors were included in the nominated DGHM2N nomogram. The area under the receiver operating characteristic curve value of the training cohort was 0.870 (95% CI: 0.841 to 0.899) and in the testing cohort was 0.822 (95% CI: 0.769 to 0.875). CONCLUSIONS: A reliable nomogram model (DGHM2N model) was developed and validated in this study. This nomogram could individually predict the adverse outcome of patients who had an AIS receiving intravenous thrombolysis with alteplase for 3 months.
