Real-World Retrospective Analysis of Alemtuzumab Outcomes in Relapsing-Remitting Multiple Sclerosis: The LEMCAM Study.

BACKGROUND: Alemtuzumab is a high-efficacy treatment approved for relapsing-remitting multiple sclerosis (RRMS). Although clinical trials and observational studies are consistent in showing its efficacy and manageable safety profile, further studies under clinical practice conditions are needed to further support its clinical use. OBJECTIVE: The aim of this observational retrospective study was to evaluate the effectiveness and safety of alemtuzumab to add to the current real-world evidence on the drug. METHODS: A cohort of 115 adult patients with RRMS treated with alemtuzumab between 2014 and 2020 was retrospectively followed up in five centers in Spain. Analysis included annualized relapse rate (ARR), 6-month confirmed disability worsening (CDW), 6-month confirmed disability improvement (CDI), radiological activity, no evidence of disease activity (NEDA-3), and safety signals. Given the different follow-up periods among participants, ARR was calculated using the person-years method. CDI was defined as a ≥ 1.0-point decrease in Expanded Disability Status Scale (EDSS) score assessed in patients with a baseline EDSS score ≥ 2.0 confirmed 6 months apart. CDW was defined as a ≥ 1.0-point increase in EDSS score assessed in patients with a baseline EDSS score ≥ 1.0 (≥ 1.5 if baseline EDSS = 0), confirmed 6 months apart. RESULTS: ARR decreased from 1.9 (95% confidence interval 1.60-2.33) in the year prior to alemtuzumab initiation to 0.28 (0.17-0.37) after 1 year of treatment (87% reduction), and to 0.22 (0.13-0.35) after the second year. Over the entire follow-up period, ARR was 0.24 (0.18-0.30). At year 1, 75% of patients showed no signs of magnetic resonance imaging (MRI) activity and 70% at year 5. One percent of patients experienced 6-month CDW at year 1, 2.6% at year 2, 7.4% at year 3, and no patients over years 4 and 5. A total of 7.7% of patients achieved 6-month CDI in year 1, 3.6% in year 2, and maintained it at years 3 and 4. Most patients achieved annual NEDA-3: year 1, 72%; year 2, 79%; year 3, 80%; year 4, 89%; year 5, 75%. Infusion-related reactions were observed in 95% of patients and infections in 74%. Thyroid disorders occurred in 30% of patients, and only three patients developed immune thrombocytopenia. No cases of progressive multifocal leukoencephalopathy were reported. CONCLUSIONS: This study shows that alemtuzumab reduced the relapse rate and disability worsening in real-world clinical practice, with many patients achieving and sustaining NEDA-3 over time. The safety profile of alemtuzumab was consistent with previous findings, and no new or unexpected safety signals were observed. As this was an observational and retrospective study, the main limitation of not having all variables comprehensively available for all patients should be considered when interpreting results.

Left Atrial Strain Predicts Stroke Recurrence and Death in Patients With Cryptogenic Stroke.

Left atrial strain (LAS) has been widely studied as a predictor of atrial fibrillation (AF) after cryptogenic stroke (CS). However, the evidence about its prognostic role in terms of stroke recurrence and death in this setting remains scarce. A total of 92 consecutive patients with ischemic stroke or transient ischemic attack with ABCD2 scale ≥4 of unknown etiology were prospectively recruited. Echocardiography, including LAS was performed during admission. The primary outcome measure was the composite of stroke recurrence or death. The mean age was 77.5 ± 7.7, and 58% of patients were female. After a median follow up of 28 months, the primary outcome measure occurred in 15 patients (16%). The primary outcome was more frequent in patients with diabetes (53% vs 21%, p = 0.02), chronic kidney disease (33% vs 10%, p = 0.034), and a history of heart failure (13% vs 0%, p = 0.025). LAS reservoir (LASr) and LAS conduit (LAScd) were lower in patients developing the primary outcome (21% ± 7% vs 28.8% ± 11%, p = 0.017 and 7.7% ± 3.9% vs 13.7% ± 7%, p = 0.007, respectively). On multivariate analysis, LASr (hazard ratio 0.9, 95% confidence interval 0.85 to 0.99, p = 0.048) and diabetes (hazard ratio 3.3, 95% confidence interval 1.03 to 10.4, p = 0.045) were associated with stroke recurrence or all-cause death after CS. On the log-rank test (using the discriminatory cut-off value of LASr <23%), LASr (p = 0.009) was associated with higher risk of the primary outcome. In conclusion, lower values of the LAS reservoir were associated with a higher risk of stroke recurrence or death after CS. LAS may identify patients at higher risk of thromboembolism and stress conditions.

Analysis of humoral and cellular immunity after SARS-CoV-2 vaccination in patients with multiple sclerosis treated with immunomodulatory drugs.

We analyzed immune response to SARS-CoV-2 vaccination by measuring specific IgG titers and T-cell reactivity to different SARS-CoV-2 peptides in multiple sclerosis patients taking different disease-modifying treatments. Of the 88 patients included, 72 developed any kind of immune response after vaccination. Although DMTs such as fingolimod and anti-CD20+ treatments prevented patients from developing a robust humoral response to the vaccine, most of them were still able to develop a cellular response, which could be crucial for long-term immunity. It is probably advisable that all MS patients take additional/booster doses to increase their humoral and/or cellular immune response to SARS-CoV-2.

Risk of recurrent stroke and mortality after cryptogenic stroke in diabetic patients.

BACKGROUND: Diabetes mellitus is a highly prevalent and growing chronic disease that is associated with increased risk of recurrence among several stroke subtypes. However, evidence on the prognostic role of diabetes in the setting of cryptogenic stroke (CS) remains scarce. METHODS: From April 2019 to November 2021, we recruited prospectively 78 consecutive patients with CS. Patients were classified according to the presence of diabetes. Main outcome was the composite of stroke recurrence and death. Secondary outcome was stroke recurrence. RESULTS: Mean age of the cohort was 78 ± 7.7 years and 18 patients (23%) had diabetes. After a median clinical follow-up of 23 months the incidence of stroke recurrence and mortality [HR 5.8 (95% CI 1.9-19), p = 0.002] and the incidence of stroke recurrence [HR 16.6 (95% CI 1.8-149), p = 0.012], were higher in patients with diabetes. After adjusting for potential confounders diabetes was identified as an independent predictor of stroke recurrence and death in patients with CS [HR 33.8 (95% CI 2.1-551), p = 0.013]. Other independent predictors of stroke recurrence and mortality were hypertension [HR 31.4 (95% CI 1.8-550), p = 0.018], NTproBNP [HR 1.002 (95% CI 1.001-1.004), p = 0.013] and chronic kidney disease (CKD) [HR 27.4 (95% CI 1.4-549) p = 0.03]. Furthermore, diabetes was an independent predictor of stroke recurrence [HR 103 (95% CI 1.3-8261), p = 0.038]. CONCLUSION: Diabetic patients with CS are at higher risk of stroke recurrence and death. Hypertension CKD and NTproBNP are also independent predictors of stroke recurrence and death after CS.

Predictive value of ischemia location on multimodal CT in thrombectomy-treated patients.

OBJECTIVE: Alberta Stroke Program Early CT Score (ASPECTS) applied to CT-perfusion (CTP) and CT-angiography-source-images (CTA-SI) may improve outcome prediction in large vessel occlusion (LVO) stroke if compared to non-contrast CT (NCCT) alone. Besides, ischemia location may have enhanced capabilities, compared to ischemia volume alone, in predicting stroke outcomes. We aim to evaluate the association between ischemia location as measured by ASPECTS regions in NCCT, CTP maps and CTA-SI and 3 months outcome in patients with LVO treated with mechanical thrombectomy (MT). MATERIAL AND METHODS: Consecutive patients with anterior circulation stroke treated with MT were recorded in a prospectively maintained database at a single center. Modified Rankin scale (mRS) at 3 months >2 was considered a poor outcome. Association of patients' characteristics, NCCT, CTP, and CTA-SI parameters with outcome was evaluated using single-variable analysis and binary logistic regression multivariate analysis for each imaging technique. RESULTS: 177 patients were included. 115 (65%) patients reached a favorable outcome. The involvement of lenticular, caudate, M1, or M2 in all imaging techniques, insula in NCCT and CTA-SI and M5 in CBV maps and CTA-SI was related to functional outcome in bivariate analysis. However, in the multivariate analysis, none ischemia location was independently related to outcome, no matter the imaging technique studied. This finding remained unchanged when restricted to patients with good recanalization and when analyzing subpopulations according to hemisphere involvement or territories association. CONCLUSIONS: Our study suggests ischemia location shouldn't be used solely for decision-making in LVO stroke patients. Its predictive value may be taken in consideration together with other clinical and radiological variables.

Advanced Echocardiography With Left Atrial Strain and Indexed Left Atrial Three-Dimensional Volume for Predicting Underlying Atrial Fibrillation After Cryptogenic Stroke.

Cryptogenic stroke (CS) represents 1/3 of ischemic strokes. Atrial fibrillation (AF) can be detected in up to 30% of CS. Therefore, there is a clinical need for predicting AF to guide the optimal secondary prevention strategy. The evidence about the role of advanced echocardiography, including left atrial 3-dimensional (3D) index volume and left atrial strain (LAS) techniques, to predict underlying AF in this setting is lacking. From April 2019 to November 2021, 78 consecutive patients with ischemic stroke or transient ischemic attack with ABCD2 scale ≥4 of unknown etiology were prospectively recruited. Echocardiography was performed during admission. All patients underwent 15 days of wearable Holter monitoring. The primary outcome measure was AF detection during follow-up. Twenty-two patients (28%) developed AF. Patients in the AF group were older (81 ± 6.3 vs 76.5 ± 7.8 years; p = 0.012). Left atrial (LA) diastolic indexed volume was higher in the AF group (37.2 ± 12.8 vs 29.7 ± 11 ml/m2 p = 0.01). Three-D LA indexed volume was also higher in patients with AF (41.4 ± 14 vs 32.2 ± 10 ml/m2 p = 0.009). LAS reservoir, LAS conduct, and LAS contraction (LASct) were significantly lower in patients with AF (19 ± 5.6 vs 32% ± 10.3%; 9 ± 4.5 vs 15 ± 7.6; 10 ± 5.3 vs 17 ± 6.4, respectively, all p <0.001). On multivariate analysis, LASct <13.5% and LA 3D indexed volume >44.5 ml/m2 were independent predictors of AF (odds ratio 10.9 [95% confidence interval 1.09 to 108.2], p = 0.042). In conclusion, LASct <13.5% and LA 3D indexed volume >44.5 ml/m2 are independent predictors of underlying AF in patients with CS. Our results show the usefulness of advanced echocardiography in this challenging clinical setting.

Implementation of physiotherapy telerehabilitation before and post Covid-19 outbreak: A comparative narrative between South American countries and Australia.

The continuous development in telecommunication tech-nologies has created opportunities for health professionals to optimise healthcare delivery by adopting digital tools into rehabilitation programs (i.e., telerehabilitation). These tech-nological advances, along with the demographic and social characteristics of each country, have made the implementa-tion of telerehabilitation a disparate process across regions. We have gathered the experience of four countries (Australia, Chile, Brazil, and Colombia) in two different regions (Ocea-nia and South America) to recompile the history pre- and post-Covid-19 outbreak until January of 2021, the barriers to, and facilitators of telerehabilitation, and outline the future challenges for these countries.

A Comprehensive Model to Predict Atrial Fibrillation in Cryptogenic Stroke: The Decryptoring Score.

OBJETIVE: Cryptogenic stroke (CS) represents up to 30% of ischemic strokes (IS). Since atrial fibrillation (AF) can be detected in up to 30% of CS, there is a clinical need for estimating the probability of underlying AF in CS to guide the optimal secondary prevention strategy. The aim of the study was to develop the first comprehensive predictive score including clinical conditions, biomarkers, and left atrial strain (LAS), to predict AF detection in this setting. METHODS: Sixty-three consecutive patients with IS or transient ischemic attack with ABCD2 scale ≥ 4 of unknown etiology were prospectively recruited. Clinical, laboratory, and echocardiographic variables were collected. All patients underwent 15 days wearable Holter-ECG monitoring. Main objective was the Decryptoring score creation to predict AF in CS. Score variables were selected by a univariate analysis and, thereafter, score points were derived according to a multivariant analysis. RESULTS: AF was detected in 15 patients (24%). Age > 75 (9 points), hypertension (1 point), Troponin T > 40 ng/L (8.5 points), NTproBNP > 200 pg/ml (0.5 points), LAS reservoir < 25.3% (24.5 points) and LAS conduct < 10.4% (0.5 points) were included in the score. The rate of AF detection was 0% among patients with a score of < 10 and 80% among patients with a score > 35. The comparison of the predictive validity between the proposed score and AF-ESUS score resulted in an AUC of 0.94 for Decryptoring score and of 0.65 for the AF-ESUS score(p < 0.001). CONCLUSION: This novel score offers an accurate AF prediction in patients with CS; however these results will require validation in an independent cohort using this model before they may be translated into clinical practice.

Fewer COVID-19-associated strokes and reduced severity during the second COVID-19 wave: The Madrid Stroke Network.

BACKGROUND AND PURPOSE: The experience gained during the first COVID-19 wave could have mitigated the negative impact on stroke care in the following waves. Our aims were to analyze the characteristics and outcomes of patients with stroke admitted during the second COVID-19 wave and to evaluate the differences in the stroke care provision compared with the first wave. METHODS: This retrospective multicenter cohort study included consecutive stroke patients admitted to any of the seven hospitals with stroke units (SUs) and endovascular treatment facilities in the Madrid Health Region. The characteristics of the stroke patients with or without a COVID-19 diagnosis were compared and the organizational changes in stroke care between the first wave (25 February to 25 April 2020) and second wave (21 July to 21 November 2020) were analyzed. RESULTS: A total of 550 and 1191 stroke patients were admitted during the first and second COVID-19 waves, respectively, with an average daily admission rate of nine patients in both waves. During the second wave, there was a decrease in stroke severity (median National Institutes of Health Stroke Scale 5 vs. 6; p = 0.000), in-hospital strokes (3% vs. 8.1%) and in-hospital mortality (9.9% vs. 15.9%). Furthermore, fewer patients experienced concurrent COVID-19 (6.8% vs. 19.1%), and they presented milder COVID-19 and less severe strokes. Fewer hospitals reported a reduction in the number of SU beds or deployment of SU personnel to COVID-19 dedicated wards during the second wave. CONCLUSIONS: During the second COVID-19 wave, fewer stroke patients were diagnosed with COVID-19, and they had less stroke severity and milder COVID-19.

Risk and outcomes of COVID-19 in patients with multiple sclerosis.

BACKGROUND AND PURPOSE: Limited information is available on incidence and outcomes of COVID-19 in patients with multiple sclerosis (MS). This study investigated the risks of SARS-CoV-2 infection and COVID-19-related outcomes in patients with MS, and compared these with the general population. METHODS: A regional registry was created to collect data on incidence, hospitalization rates, intensive care unit admission, and death in patients with MS and COVID-19. National government outcomes and seroprevalence data were used for comparison. The study was conducted at 14 specialist MS treatment centers in Madrid, Spain, between February and May 2020. RESULTS: Two-hundred nineteen patients were included in the registry, 51 of whom were hospitalized with COVID-19. The mean age ± standard deviation was 45.3 ± 12.4 years, and the mean duration of MS was 11.9 ± 8.9 years. The infection incidence rate was lower in patients with MS than the general population (adjusted incidence rate ratio = 0.78, 95% confidence interval [CI] = 0.70-0.80), but hospitalization rates were higher (relative risk = 5.03, 95% CI = 3.76-6.62). Disease severity was generally low, with only one admission to an intensive care unit and five deaths. Males with MS had higher incidence rates and risk of hospitalization than females. No association was found between the use of any disease-modifying treatment and hospitalization risk. CONCLUSIONS: Patients with MS do not appear to have greater risks of SARS-CoV-2 infection or severe COVID-19 outcomes compared with the general population. The decision to start or continue disease-modifying treatment should be based on a careful risk-benefit assessment.

Stroke Acute Management and Outcomes During the COVID-19 Outbreak: A Cohort Study From the Madrid Stroke Network.

BACKGROUND AND PURPOSE: The coronavirus disease 2019 (COVID-19) outbreak has added challenges to providing quality acute stroke care due to the reallocation of stroke resources to COVID-19. Case series suggest that patients with COVID-19 have more severe strokes; however, no large series have compared stroke outcomes with contemporary non-COVID-19 patients. Purpose was to analyze the impact of COVID-19 pandemic in stroke care and to evaluate stroke outcomes according to the diagnosis of COVID-19. METHODS: Retrospective multicenter cohort study including consecutive acute stroke patients admitted to 7 stroke centers from February 25 to April 25, 2020 (first 2 months of the COVID-19 outbreak in Madrid). The quality of stroke care was measured by the number of admissions, recanalization treatments, and time metrics. The primary outcome was death or dependence at discharge. RESULTS: A total of 550 acute stroke patients were admitted. A significant reduction in the number of admissions and secondary interhospital transfers was found. COVID-19 was confirmed in 105 (19.1%) patients, and a further 19 patients were managed as suspected COVID-19 (3.5%). No differences were found in the rates of reperfusion therapies in ischemic strokes (45.5% non-COVID-19, 35.7% confirmed COVID-19, and 40% suspected COVID-19; P=0.265). However, the COVID-19 group had longer median door-to-puncture time (110 versus 80 minutes), which was associated with the performance of chest computed tomography. Multivariate analysis confirmed poorer outcomes for confirmed or suspected COVID-19 (adjusted odds ratios, 2.05 [95% CI, 1.12-3.76] and 3.56 [95% CI, 1.15-11.05], respectively). CONCLUSIONS: This study confirms that patients with COVID-19 have more severe strokes and poorer outcomes despite similar acute management. A well-established stroke care network helps to diminish the impact of such an outbreak in stroke care, reducing secondary transfers and allowing maintenance of reperfusion therapies, with a minor impact on door-to-puncture times, which were longer in patients who underwent chest computed tomography.

COVID-19 in 7 multiple sclerosis patients in treatment with ANTI-CD20 therapies.

BACKGROUND AND AIM: In December 2019, the first cases of SARS-CoV-2 infection were detected in Wuhan. Within two months, it had begun to spread around the world in what became an unprecedented pandemic. Patients with Multiple Sclerosis (MS) in a state of immunosuppression may be considered at risk for complications in the COVID-19 pandemic, although there is increasing evidence postulating a possible protective role of selective immunosuppression. One group of such immunosuppressants used in MS comprises the anti-CD20 monoclonal antibodies (mAbs) ocrelizumab and rituximab. Anti-CD20 mAbs bind to the surface of B cells, causing their depletion. We describe our experience in seven cases of patients with multiple sclerosis who have been affected by SARS-COV-2 (with a clinical/serological diagnosis or PCR diagnosis) and who were being treated with anti-CD20+ monoclonal antibodies. MATERIAL AND METHODS: We review the development of patients during infection as well as the resolution of their clinical picture. We also analyze the serology status against SARS-CoV-2 after resolution of the infection. RESULTS: Although the severity of the clinical pictures was variable, patients' development was good. Not all patients, however, developed antibodies against SARS-CoV-2. CONCLUSIONS: Patients treated with anti-CD20+ have adequate resolution of COVID-19 despite the fact that the presence of antibodies against SARS-CoV-2 was not detected in all cases. It is possible that the presence of humoral immunity is not always necessary fora good clinical course of SARS-CoV-2 infection.

Covid-19 in a patient with multiple sclerosis treated with natalizumab: May the blockade of integrins have a protective role?

The disease caused by the new coronavirus SARS-CoV-2 (COVID-19) is currently spread worldwide . Recent data supports SARS-CoV-2 may use integrins to enter human cells. Therefore, anti-integrins therapies might be an alternative against the infection . Natalizumab, approved for Multiple Sclerosis (MS) treatment, acts blocking α4-integrin. We report a MS patient treated with natalizumab who develops COVID-19, with excellent recovery and repeated negative results in 5 consecutive microbiological studies. We postulate this may be due to the blockade of integrins induced by natalizumab.

Assessment of Collateral Circulation Using Perfusion CT in Middle Cerebral Artery Thrombectomy-Treated Patients.

INTRODUCTION: The prognostic value of leptomeningeal collateral circulation in thrombectomy-treated patients remains unclear. We evaluated the construct validity of assessing leptomeningeal collateral circulation using a new regional perfusion CT source image-based approach, the Perfusion Acquisition for THrombectomy Scale (PATHS). We also compared the prognostic value of PATHS with a further 6 scales based on various techniques: CT-angiography, perfusion CT, and digital subtraction angiography. Additionally, we studied the relationship between the scores for the different scales. PATIENTS AND METHODS: We performed a retrospective study of consecutive patients with stroke and M1/terminal carotid occlusion treated with thrombectomy in our center. Leptomeningeal collateral circulation was prospectively evaluated using 7 scales: Tan and Miteff (CT Angiography); Calleja, Cao, American Society of Intervention and Therapeutic Neuroradiology/Society of Interventional Radiology, and PATHS (perfusion); and Christoforidis (Digital Subtraction Angiography). Correlations were studied using the Spearman method. RESULTS: The study population comprised 108 patients. All scales predicted the modified Rankin Scale at 3 months (P ≤ .02) and all but 1 (Christoforidis) correlated with 24-hour brain infarct volume (P ≤ .02). These correlations were higher with PATHS (rho = -0.47, P < .001 for 3-month modified Rankin Scale; rho = -0.35, P < .001 for follow-up infarct volume). The multivariate analysis showed PATHS to be an independent predictor of modified Rankin Scale at 3 months less than equal to 2. A crosscorrelation analysis revealed a better correlation between scales that used the same techniques. CONCLUSIONS: PATHS can be used to assess leptomeningeal collateral circulation. PATHS had better prognostic value than other scales; therefore, it might be considered for assessment of leptomeningeal collateral circulation in candidates for thrombectomy. The moderate correlation between scales suggests that scores are not interchangeable.

Cytomegalovirus primary infection in a patient with multiple sclerosis treated with alemtuzumab.

Alemtuzumab is an anti-CD52 monoclonal antibody approved for the treatment of multiple sclerosis (MS). It produces rapid depletion of T and B lymphocytes, which could predispose to opportunistic infections. We report one patient with MS who develops cytomegalovirus (CMV) primary infection after a third cycle of alemtuzumab, with spontaneous recovery associated with rapid lymphocyte reconstitution.

Efecto agudo del ejercicio físico de intensidad moderada sobre las variables espirométricas en sujetos asmáticos broncodilatados. Prueba piloto / Acute effect of moderate-intensity exercise on spirometric variables in broncodilated asthmatic subjects. A pilot study

RESUMEN Introducción: el broncoespasmo inducido por el ejercicio (BIE) ocurre entre el 70 y 80 % de los asmáticos y su aparición es más frecuente al terminar una sesión de ejercicio físico, principalmente de intensidad vigorosa. Objetivo: evaluar el efecto agudo que puede tener el ejercicio físico de intensidad moderada sobre las variables espirométricas en sujetos asmáticos broncodilatados. Metodología: se realizó un estudio cuasi-experimental de tipo antes y después. Se incluyeron diez sujetos (edad promedio = 23 ± 4 años), los cuales fueron divididos en dos grupos: cinco sujetos asmáticos y cinco sanos. Los dos grupos realizaron 10 minutos de calentamiento, 20 minutos de ejercicio en banda sin fin al 60 % de la frecuencia cardíaca de entrenamiento, seguido de 5 minutos de recuperación. La función pulmonar fue evaluada antes del ejercicio y 15 minutos después del ejercicio. Resultados: se encontraron diferencias estadísticamente significativas entre grupos (con asma 6 % vs. sin asma -1 %, p = 0,03) en los cambios pre y pos del ejercicio de la relación del volumen espiratorio forzado en el primer segundo (VEF1) sobre la capacidad vital forzada (CVF). El análisis multivariado mostró que la CVF post ejercicio en el grupo con asma fue significativamente menor que el del grupo sin asma, ajustado por evaluación basal y masa corporal total. Conclusión: el ejercicio de intensidad moderada en banda sin fin, no mostró diferencias clínicamente significativas sobre los cambios del pre y post ejercicio de las variables espirométricas estudiadas, puesto que estos cambios en VEF1 o CVF no superaron el 10 % teniendo como referencia la evaluación basal.

SUMMARY Background: Exercise-Induced Bronchospasm (BIE) occurs in 70 % to 80 % of asthmatics and its occurrence is more frequent at the end of a session of physical exercise, mainly of vigorous intensity. Objective: To evaluate the acute effect of moderateintensity physical exercise on spirometric variables in asthmatic subjects. Methodology: A before-and-after type quasi-experimental design. Ten subjects were included (mean age= 23 ± 4 years), which were divided into two groups: five asthmatic subjects and five healthy subjects. Both groups performed 10 min of warm-up, 20 min of treadmill exercise at an intensity of 60 % of the Heart Rate Reserve, and a final cool-down of 5 minutes. Lung function was assessed before and 15 minutes after exercise. Results: There were statistically significant differences between groups (with asthma = 6 % vs. without asthma = -1 %, p = 0.03) in the pre-post-exercise changes of the ratio of the forced expiratory volume in one second and the forced vital capacity (FEV1/FVC). The multivariate analysis showed that post-exercise FVC in subjects with asthma was significantly lower than in subjects without asthma, after adjusting for the baseline assessment and total body mass. Conclusion: Moderate-intensity exercise on a treadmill did not shows clinically significant differences on the changes pre-post exercise of the studied spirometric variables, since the changes on FEV1 or FVC did not exceed 10 % having as reference the baseline evaluation.

Mechanical thrombectomy in orally anticoagulated patients with acute ischemic stroke.

BACKGROUND AND PURPOSE: To investigate the efficacy and safety of mechanical thrombectomy in patients with acute ischemic stroke according to the oral anticoagulation medication taken at the time of stroke onset. MATERIALS AND METHODS: A retrospective multicenter study of prospectively collected data based on data from the registry the Madrid Stroke Network was performed. We included consecutive patients with acute ischemic stroke treated with mechanical thrombectomy and compared the frequency of intracranial hemorrhage and the modified Rankin Scale (mRS) score at 3 months according to anticoagulation status. RESULTS: The study population comprised 502 patients, of whom 389 (77.5%) were not anticoagulated, 104 (20.7%) were taking vitamin K antagonists, and 9 (1.8%) were taking direct oral anticoagulants. Intravenous thrombolysis had been performed in 59.8% and 15.0% of non-anticoagulated and anticoagulated patients, respectively. Rates of intracranial hemorrhage after treatment were similar between non-anticoagulated and anticoagulated patients, as were rates of recanalization. After 3 months of follow-up, the mRS score was ≤2 in 56.3% and 55.7% of non-anticoagulated and anticoagulated patients, respectively (P=NS). Mortality rates were similar in the two groups (13.1%and12.4%, respectively). Among anticoagulated patients, no differences were found for intracranial bleeding, mRS score, or mortality rates between patients taking vitamin K antagonists and those taking direct oral anticoagulants. CONCLUSIONS: Mechanical thrombectomy is feasible in anticoagulated patients with acute ischemic stroke. The outcomes and safety profile are similar to those of patients with no prior anticoagulation therapy.

Do people with epilepsy have a different lifestyle?

BACKGROUND: Epilepsy is one of the most common neurological diseases. Its high prevalence, economic relevance and impact on daily life make it crucial that we study this condition in further detail. Our study seeks to investigate whether the lifestyle of people diagnosed with epilepsy is different to that of people without epilepsy, in order to better understand our patients. METHODS: We designed and delivered a questionnaire about quality of life and daily habits to patients from our hospital's Epilepsy Unit. We also delivered the questionnaire to a control group with similar demographic characteristics. Lifestyle differences between patients and control group members were analyzed. Patients were further divided according to the type of epilepsy, time since diagnosis, seizure frequency and pharmacotherapy. RESULTS: A total of 278 people were interviewed (85 patients, 193 controls). There was no difference in educational level, marital status and healthy habits (sports, reading and diet) between the groups. However, patients with epilepsy were more often unemployed (p<0.05) and had a healthier lifestyle (lower body mass index, lower alcohol consumption and a tendency towards smoking less). Anxiolytic-antidepressant intake was higher in patients with epilepsy. In terms of the type of epilepsy, patients with focal epilepsy exercised more than those with generalized epilepsy; no other statistically significant differences were found between the individuals studied. DISCUSSION: Epilepsy diagnosis does not seem to negatively alter the daily life of patients; in fact, many adopt a healthier lifestyle after diagnosis. The risk of antidepressant/anxiolytic intake is, however, higher, which could reflect the impact this chronic condition still has at a social level.
