• In adults and elderly patients with seizure cluster after i.v. brivaracetam administration no other rescue medications were needed in 77% of the cases. • A lower risk of evolution into status epilepticus was observed when BRV was used as first-line drug. • The underlyng etiology was one of the main outcome predictors of response of the seizure cluster. • No severe treatment emergent adverse events were observed after i.v. brivaracetam. Nearly half of people with epilepsy (PWE) are expected to develop seizure clusters (SC), with the subsequent risk of hospitalization. The aim of the present study was to evaluate the use, effectiveness and safety of intravenous (IV) brivaracetam (BRV) in the treatment of SC. Retrospective multicentric study of patients with SC (≥ 2 seizures/24 h) who received IV BRV. Data collection occurred from January 2019 to April 2022 in 25 Italian neurology units. Primary efficacy outcome was seizure freedom up to 24 h from BRV administration. We also evaluated the risk of evolution into Status Epilepticus (SE) at 6, 12 and 24 h after treatment initiation. A Cox regression model was used to identify outcome predictors. 97 patients were included (mean age 62 years), 74 (76%) of whom had a history of epilepsy (with drug resistant seizures in 49% of cases). BRV was administered as first line treatment in 16% of the episodes, while it was used as first or second drug after benzodiazepines failure in 49% and 35% of episodes, respectively. On the one hand, 58% patients were seizure free at 24 h after BRV administration and no other rescue medications were used in 75 out of 97 cases (77%) On the other hand, SC evolved into SE in 17% of cases. A higher probability of seizure relapse and/or evolution into SE was observed in patients without a prior history of epilepsy (HR 2.0; 95% CI 1.03 – 4.1) and in case of BRV administration as second/third line drug (HR 3.2; 95% CI 1.1 – 9.7). No severe treatment emergent adverse events were observed. In our cohort, IV BRV resulted to be well tolerated for the treatment of SC and it could be considered as a treatment option, particularly in case of in-hospital onset. However, the underlying etiology seems to be the main outcome predictor. [ABSTRACT FROM AUTHOR]

Background: Acute brain injury (ABI) can cause out of hospital cardiac arrest (OHCA). The aim of this study was to compare clinical features, mortality and potential for organ donation in patients with OHCA due to ABI vs other causes.Methods: From January 2017 to December 2018, all adult patients presenting to ED for OHCA were considered for the study. Two physicians established the definitive cause of OHCA, according to clinical, laboratory, diagnostic imaging and autoptic findings. Clinical features in patients with OHCA due to ABI or other causes were compared.Results: 280 patients were included in the analysis. ABI was the third most frequent cause of OHCA (21, 7.5%); ABIs were 8 subarachnoid hemorrhage, 8 intracerebral hemorrhage, 2 ischemic stroke, 2 traumatic spinal cord injury and 1 status epilepticus respectively. Neurological prodromes such as seizure, headache and focal neurological signs were significantly more frequent in patients with OHCA due to ABI (OR 5.34, p = 0.03; OR 12.90, p = 0.02; and OR 66.53, p < 0.01 respectively) while among non-neurological prodromes chest pain and dyspnea were significantly more frequent in patients with OHCA due to other causes (OR 14.5, p < 0.01; and OR 10.4, p = 0.02 respectively). Anisocoria was present in 19% of patients with OHCA due to ABI vs 2.7% due to other causes (OR 8.47, p < 0.01). In 90.5% of patients with ABI and in 53.1% of patients with other causes the first cardiac rhythm was non shockable (OR 8.1; p = 0.05). Multivariate logistic regression analysis revealed that older age, active smoking, post-traumatic OHCA, neurological prodromes, anisocoria at pupillary examination were independently associated with OHCA due to ABI. Patients with ABI showed a higher mortality compared with the other causes group (19 pts., 90.5% versus 167 pts., 64.5%; p = 0.015). Potential organ donors were more frequent among ABI than other causes group (10 pts., 47.6% vs 75 pts., 28.9%) however the difference did not reach the statistical significance (p = 0.07).Conclusions: ABI is the third cause of OHCA. Neurological prodromes, absence of chest pain and dyspnea before cardiac arrest, anisocoria and initial non-shockable rhythm might suggest a neurological etiology of the cardiac arrest. Patients with OHCA due to ABI has an unfavorable outcome, however, they could be candidate to organ donation. [ABSTRACT FROM AUTHOR]

Purpose: to evaluate the use, effectiveness, and adverse events of intravenous brivaracetam (BRV) in status epilepticus (SE).Methods: a retrospective multicentric study involving 24 Italian neurology units was performed from March 2018 to June 2020. A shared case report form was used across participating centres to limit biases of retrospective data collection. Diagnosis and classification of SE followed the 2015 ILAE proposal. We considered a trial with BRV a success when it was the last administered drug prior the clinical and/or EEG resolution of seizures, and the SE did not recur during hospital observation. In addition, we considered cases with early response, defined as SE resolved within 6 h after BRV administration.Results: 56 patients were included (mean age 62 years; 57 % male). A previous diagnosis of epilepsy was present in 21 (38 %). Regarding SE etiology classification 46 % were acute symptomatic, 18 % remote and 16 % progressive symptomatic. SE episodes with prominent motor features were the majority (80 %). BRV was administered as first drug after benzodiazepine failure in 21 % episodes, while it was used as the second or the third (or more) drug in the 38 % and 38 % of episodes respectively. The median loading dose was 100 mg (range 50-300 mg). BRV was effective in 32 cases (57 %). An early response was documented in 22 patients (39 % of the whole sample). The use of the BRV within 6 h from SE onset was independently associated to an early SE resolution (OR 32; 95 % CI 3.39-202; p = 0.002). No severe treatment emergent adverse events were observed.Conclusion: BRV proved to be useful and safe for the treatment of SE. Time to seizures resolution appears shorter when it is administered in the early phases of SE. [ABSTRACT FROM AUTHOR]

Objectives: Despite emerging evidences on the clinical usefulness of lung ultrasound (LUS), international guidelines still do not recommend the use of sonography for the diagnosis of pneumonia. Our study assesses the accuracy of LUS for the diagnosis of lung consolidations when compared to chest computed tomography (CT).Methods: This was a prospective study on an emergency department population complaining of respiratory symptoms of unexplained origin. All patients who had a chest CT scan performed for clinical reasons were consecutively recruited. LUS was targeted to evaluate lung consolidations with the morphologic characteristics of pneumonia, and then compared to CT.Results: We analyzed 285 patients. CT was positive for at least one consolidation in 87 patients. LUS was feasible in all patients and in 81 showed at least one consolidation, with a good inter-observer agreement (k = 0.83), sensitivity 82.8% (95% CI 73.2%-90%) and specificity 95.5% (95% CI 91.5%-97.9%). Sensitivity raised to 91.7% (95% CI 61.5%-98.6%) and specificity to 97.4% (95% CI 86.5%-99.6%) in patients complaining of pleuritic chest pain. In a subgroup of 190 patients who underwent also chest radiography (CXR), the sensitivity of LUS (81.4%, 95% CI 70.7%-89.7%) was significantly superior to CXR (64.3%, 95% CI 51.9%-75.4%) (P<.05), whereas specificity remained similar (94.2%, 95% CI 88.4%-97.6% vs. 90%, 95% CI 83.2%-94.7%).Conclusions: LUS represents a reliable diagnostic tool, alternative to CXR, for the bedside diagnosis of lung consolidations in patients with respiratory complains.

Study objective: We investigate the prognostic value of plasma lactate levels in patients with acute pulmonary embolism. Methods: We studied adult patients with symptomatic, objectively confirmed pulmonary embolism presenting to a single emergency department. Plasma lactate and troponin I levels were tested at presentation. We considered lactate values greater than or equal to 2 mmol/L and troponin I values greater than or equal to 0.10 ng/mL to be abnormal. Right-sided ventricular dysfunction was assessed by echocardiography. Primary endpoint was all-cause death occurring on or before 30 days after presentation. Secondary endpoints were the composite of all-cause death and clinical deterioration (defined as progression to shock, mechanical ventilation, or cardiopulmonary resuscitation) and death caused by pulmonary embolism. We tested the association between lactate level greater than or equal to 2 mmol/L and the endpoints using Cox proportional hazards regression analysis. Results: Of the 270 patients included in the study, the mean age was 73 years (SD 12.7 years) and 151 (55.9%) were women. Twelve patients (4.4%) showed shock or hypotension (shock or systolic arterial pressure <100 mm Hg) at presentation, 109 (40.4%) had right-sided ventricular dysfunction, 93 (34.4%) showed troponin I level greater than or equal to 0.10 ng/mL, and 81 (30%) showed lactate level greater than or equal to 2 mmol/L. Seventeen patients (6.3%) died, 12 (4.4%) because of pulmonary embolism, and 37 (13.7%) reached the composite endpoint. Patients with lactate level greater than or equal to 2 mmol/L showed higher mortality (17.3%; 95% confidence interval [CI] 11.9% to 20%) than patients with a lower level (1.6%; 95% CI 0.8% to 1.9%). Plasma lactate level was associated with all-cause death (hazard ratio 11.67; 95% CI 3.32 to 41.03) and the composite endpoint (hazard ratio 8.14; 95% CI 3.83 to 17.34) independent of shock or hypotension, right-sided ventricular dysfunction, or elevation of troponin I values. Conclusion: Patients with pulmonary embolism and elevated plasma lactate level are at high risk of death and adverse outcome, independent of shock or hypotension, or right-sided ventricular dysfunction or injury markers.

This paper reviews, compares, and analyzes the legal and institutional frameworks of the Disaster Management (DM) systems in India and Nigeria. This research aims to study the effectiveness and efficacy of the DM systems in both countries to identify the strengths and weaknesses and make recommendations for enhancing the current systems. The study initially provides a comprehensive introduction of Indian and Nigerian DM systems, including the countries' disaster profiles and the current DM policies and institutional frameworks, then compares them from various perspectives to identify the similarities, differences, common challenges, and lessons learned. An intense documentary survey of relevant literature is applied in this study to obtain data and information. The study finds that India, by developing better legal and institutional frameworks, creates a more effective DM system than Nigeria in terms of the integration and prioritization of Disaster Risk Reduction (DRR) efforts, community participation and coordination, and collaboration mechanisms. The research also discovers that both nations struggle to mobilize, manage, and utilize DM funds due to a lack of transparency in funding sources, particularly at the state and local/district levels. The findings also show that both countries' DM systems are mainly focused on natural disasters, with little emphasis provided on effective preventative and regulatory measures to deal with the risks and consequences of man-made hazards. The paper concludes that due to administrative and financial issues, none of the two countries achieved total success in capacity building activities. [ABSTRACT FROM AUTHOR]
