RESUMO
BACKGROUND: Randomized controlled trials (RCTs) proved that short-term (21-90 days) dual antiplatelet therapy (DAPT) reduces the risk of early ischemic recurrences after a noncardioembolic minor stroke or high-risk transient ischemic attack (TIA) without substantially increasing the hemorrhagic risk. We aimed at understanding whether and how real-world use of DAPT differs from RCTs. METHODS: READAPT (Real-Life Study on Short-Term Dual Antiplatelet Treatment in Patients With Ischemic Stroke or TIA) is a prospective cohort study including >18-year-old patients treated with DAPT after a noncardioembolic minor ischemic stroke or high-risk TIA from 51 Italian centers. The study comprises a 90-day follow-up from symptom onset. In the present work, we reported descriptive statistics of baseline data of patients recruited up to July 31, 2022, and proportions of patients who would have been excluded from RCTs. We compared categorical data through the χ² test. RESULTS: We evaluated 1070 patients, who had 72 (interquartile range, 62-79) years median age, were mostly Caucasian (1045; 97.7%), and were men (711; 66.4%). Among the 726 (67.9%) patients with ischemic stroke, 226 (31.1%) did not meet the RCT inclusion criteria because of National Institutes of Health Stroke Scale score >3 and 50 (6.9%) because of National Institutes of Health Stroke Scale score >5. Among the 344 (32.1%) patients with TIA, 69 (19.7%) did not meet the RCT criteria because of age, blood pressure, clinical features, duration of TIA, presence of diabetes score <4 and 252 (74.7%) because of age, blood pressure, clinical features, duration of TIA, presence of diabetes score <6 and no symptomatic arterial stenosis. Additionally, 144 (13.5%) patients would have been excluded because of revascularization procedures. Three hundred forty-five patients (32.2%) did not follow the RCT procedures because of late (>24 hours) DAPT initiation; 776 (72.5%) and 676 (63.2%) patients did not take loading doses of aspirin and clopidogrel, respectively. Overall, 84 (7.8%) patients met the RCT inclusion/exclusion criteria. CONCLUSIONS: The real-world use of DAPT is broader than RCTs. Most patients did not meet the RCT criteria because of the severity of ischemic stroke, lower risk of TIA, late DAPT start, or lack of antiplatelet loading dose. REGISTRATION: URL: https://www.

INTRODUCTION: Nonketotic hyperglycemic hyperosmolar state (NKHHS) is associated with a wide spectrum of neurological syndromes including acute stroke-like deficits. Clinical features and etiology have not been established yet. METHODS: Here we provide a case illustration and systematic review on non-epileptic acute neurological deficits in NKHSS. The systematic literature search followed PRISMA guidelines and a predefined protocol, including cases of NKHSS with acute stroke-like presentation. RESULTS: The database search yielded 18 cases. Hemianopia was the most common clinical presentation (73%), followed by partial or total anterior circulation syndrome (26%). Patients with symptoms of acute anterior circulation infarct were significantly older (69.5 ± 5.1 vs. 52.2 ± 13.9 years; p = 0.03) and showed higher mean glucose levels at the admission vs. those with hemianopia (674.8 ± 197.2 vs. 529.4 ± 190.8 mg/dL; p = 0.16). Brain MRI was performed in 89% of patients, resulting abnormal in 71% of them, especially hemianopic (91%). Subcortical hypointensities in T2-FLAIR MR sequences were present in all the analyzed cases. Cortical DWI hyperintensities were also common (64%). EEG showed diffuse or focal slow wave activity in 68% of patients, especially with visual hallucinations (85%). Neurological symptoms completely resolved in 78% of patients within 6 (IQR 3-10) days, following aggressive treatment and glucose normalization. CONCLUSIONS: Our results suggest neuronal dysfunction on a metabolic basis as the leading cause of acute neurological deficits in NKHHS. Despite the generally favorable prognosis, prompt identification and aggressive treatment are crucial to avoid irreversible damage. Larger cohort studies are needed to confirm our findings.

OBJECTIVE: To determine whether erenumab is effective and safe in refractory chronic migraine with medication overuse headache. METHODS: In this prospective, multicentric, real-life study, chronic migraine with medication overuse headache patients who received erenumab were recruited. Study inclusion was limited to patients who previously failed onabotulinumtoxinA in addition to at least three other pharmacological commonly used migraine preventive medication classes. RESULTS: Of 396 patients who received erenumab, 38% (n = 149) met inclusion criteria. After 3 months, 51% (n = 76) and 20% (n = 30) patients achieved ≥ 50% and ≥ 75% reduction in monthly headache days, respectively. Monthly pain medications intake decreased from 46.1 ± 35.3 to 16.8 ± 13.9 (p < 0.001), while monthly headache days decreased from 25.4 ± 5.4 to 14.1 ± 8.6 (p < 0.001). Increasing efficacy of erenumab over the study period was observed. Allodynia was a negative predictive factor of erenumab response (odds ratio = 0.47; p = 0.03). Clinical conversion to episodic migraine with no medication overuse was observed in 64% (n = 96) patients. No serious adverse events were observed. CONCLUSIONS: Erenumab reduced significantly migraine frequency and pain medication intake in refractory chronic migraine with MOH patients.

INTRODUCTION: Long-term (1-year) fremanezumab treatment proved to be effective, safe, and well tolerated in individuals with migraine and < 2 medication clusters in a randomized controlled trial (RCT). We aimed to assess real-world evidence (RWE), long-term effectiveness, tolerability, and safety of fremanezumab in people with high-frequency episodic migraine (HFEM) or chronic migraine (CM) with > 3 treatment failures and various comorbidities. METHODS: A 48-week, prospective, multicenter (n = 26), cohort study assessed fremanezumab's effectiveness, safety, and tolerability in consecutive adults with HFEM or CM with > 3 treatment failures. Primary endpoint was variation from baseline in monthly migraine days (MMD) in HFEM and monthly headache days (MHD) in CM at weeks 45-48. Secondary endpoints were changes in monthly analgesic medications, Numerical Rating Scale (NRS), Headache Impact Test (HIT-6), and the Migraine Disability Assessment Scale (MIDAS) scores and ≥ 50%, ≥ 75%, and 100% responder rates. RESULTS: Of 533 participants who had received ≥ 1 fremanezumab dose, 130 were treated for ≥ 48 weeks and considered for effectiveness analysis. No participant missed any treatment dosage every other consecutive month during the 12-month period. PRIMARY ENDPOINT: fremanezumab significantly (p < 0.001) reduced both MMD (- 6.4) in HFEM and MHD (- 14.5) in CM. Secondary endpoints: a significant reduction (p < 0.001) was observed in monthly analgesic medications (HFEM - 6.0; CM -16.5), NRS (HFEM - 3.4; CM - 3.4), HIT-6 (HFEM - 16.9; CM - 17.9) and MIDAS score (HFEM - 50.4; CM - 76.6). The ≥ 50%, ≥ 75%, and 100% response rates to fremanezumab were 75.5%, 36.7%, and 2% in HFEM and 71.6%, 44.4%, and 3.7% in CM. Corresponding response rates were 60.5%, 37.2%, and 2.3% in individuals with psychiatric comorbidities, 74.2%, 50%, and 4.8% in CM with medication overuse, and 60.9%, 39.1%, and 4.3% in CM with medication overuse and psychiatric comorbidities. Mild and transient treatment-emergent adverse events occurred in 7.8% of the participants. No subject discontinued the treatment for any reason. CONCLUSION: This RWE study documents that long-term fremanezumab treatment is highly effective and remarkably well tolerated in subjects with HFEM or CM with multiple (> 3) therapeutic failures, even in the presence of concomitant medication overuse, psychiatric comorbidities, or both. The effectiveness-to-tolerability ratio appears to be better in RWE than in RCTs.
RESUMO
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.

BACKGROUND AND PURPOSE: Randomized controlled trials (RCTs) proved the efficacy of short-term dual antiplatelet therapy (DAPT) in secondary prevention of minor ischemic stroke or high-risk transient ischemic attack (TIA). We aimed at evaluating effectiveness and safety of short-term DAPT in real-world, where treatment use is broader than in RCTs. METHODS: READAPT (REAl-life study on short-term Dual Antiplatelet treatment in Patients with ischemic stroke or Transient ischemic attack) (NCT05476081) was an observational multicenter real-world study with a 90-day follow-up. We included patients aged 18+ receiving short-term DAPT soon after ischemic stroke or TIA. No stringent NIHSS and ABCD2 score cut-offs were applied but adherence to guidelines was recommended. Primary effectiveness outcome was stroke (ischemic or hemorrhagic) or death due to vascular causes, primary safety outcome was moderate-to-severe bleeding. Secondary outcomes were the type of ischemic and hemorrhagic events, disability, cause of death, and compliance to treatment. RESULTS: We included 1920 patients; 69.9% started DAPT after an ischemic stroke; only 8.9% strictly followed entry criteria or procedures of RCTs. Primary effectiveness outcome occurred in 3.9% and primary safety outcome in 0.6% of cases. In total, 3.3% cerebrovascular ischemic recurrences occurred, 0.2% intracerebral hemorrhages, and 2.7% bleedings; 0.2% of patients died due to vascular causes. Patients with NIHSS score ⩽5 and those without acute lesions at neuroimaging had significantly higher primary effectiveness outcomes than their counterparts. Additionally, DAPT start >24 h after symptom onset was associated with a lower likelihood of bleeding. CONCLUSIONS: In real-world, most of the patients who receive DAPT after an ischemic stroke or a TIA do not follow RCTs entry criteria and procedures. Nevertheless, short-term DAPT remains effective and safe in this population. No safety concerns are raised in patients with low-risk TIA, more severe stroke, and delayed treatment start.
RESUMO
Increased incidence rates of amyotrophic lateral sclerosis (ALS) have been recently reported across various Western countries, although geographic and temporal variations in terms of incidence, clinical features and genetics are not fully elucidated. This study aimed to describe demographic, clinical feature and genotype-phenotype correlations of ALS cases over the last decade in the Emilia Romagna Region (ERR). From 2009 to 2019, our prospective population-based registry of ALS in the ERR of Northern Italy recorded 1613 patients receiving a diagnosis of ALS. The age- and sex-adjusted incidence rate was 3.13/100,000 population (M/F ratio: 1.21). The mean age at onset was 67.01 years; women, bulbar and respiratory phenotypes were associated with an older age, while C9orf72-mutated patients were generally younger. After peaking at 70-75 years, incidence rates, among women only, showed a bimodal distribution with a second slight increase after reaching 90 years of age. Familial cases comprised 12%, of which one quarter could be attributed to an ALS-related mutation. More than 70% of C9orf72-expanded patients had a family history of ALS/fronto-temporal dementia (FTD); 22.58% of patients with FTD at diagnosis had C9orf72 expansion (OR 6.34, p = 0.004). In addition to a high ALS incidence suggesting exhaustiveness of case ascertainment, this study highlights interesting phenotype-genotype correlations in the ALS population of ERR.
RESUMO
Friedreich ataxia is the most common form of hereditary ataxia. Heart involvement in Friedreich ataxia is common and can include increased left ventricular wall thickness, atrial fibrillation, and in the later stages, a reduction of left ventricular ejection fraction. We present the case of a 45-year-old man with a history of paroxysmal atrial fibrillation and a congestive heart failure, hypertension, age ⩾ 75 years, diabetes mellitus, stroke, vascular disease, age 65-74 years, and female sex (CHA2DS2-VASc) score of only 1 (because of reduced left ventricular ejection fraction) who presented with pneumonia and was also found to have atrial fibrillation with a rapid ventricular response. Despite already being on long-term therapy with a non-vitamin K-antagonist oral anticoagulant, a transesophageal echocardiogram showed a mobile floating thrombus in the left atrial appendage. In accordance with previous necropsy evidence of thrombosis and thromboembolism in Friedreich ataxia subjects who likely have had only non-sex-related CHA2DS2-VASc score ⩽1, this case suggests that the risk of thromboembolism in Friedreich ataxia subjects with atrial fibrillation may not be adequately predicted by the sole CHA2DS2-VASc score.

OBJECTIVE: To provide to emergency department (ED) physicians with guidelines for diagnosis of patients with nontraumatic headaches. BACKGROUND: Many patients present to an ED with the chief complaint of headache. Causes of nontraumatic headache include life-threatening illnesses, and distinguishing patients with such ominous headaches from those with a primary headache disorder can be challenging for the ED physician. CONCLUSION: We present a consensus statement aimed to be a useful tool for ED doctors in making evidence-based diagnostic decisions in the management of adult patients with nontraumatic headache. METHODS: A multidisciplinary work performed an extensive review of the medical literature and applied the information obtained to commonly encountered scenarios in the ED.
