- Five-Year Outcome in Stroke Patients Submitted to ThrombolysisPublication . Machado, C; Pinho, J; Alves, JN; Santos, AF; Ferreira, MC; Abreu, MJ; Oliveira, L; Mota, J; Fontes, JR; Ferreira, CBACKGROUND AND PURPOSE: Little is known on long-term follow-up after thrombolysis in ischemic stroke patients because the majority of studies evaluated outcome at 3 to 12 months. We aimed to assess 5-year outcome after intravenous thrombolysis (IVT). METHODS: Cohort study based on the prospective registry of all consecutive ischemic stroke patients submitted to IVT in our Stroke Unit. Five-year outcome, including living settings, functional outcome, stroke recurrence, and mortality, was ascertained by telephonic interviews and additional review of clinical records. Multivariate analyses were performed to identify predictors of outcome and mortality. Excellent outcome was defined as modified Rankin scale 0 to 1. RESULTS: Five-year outcome was available for 155/164 patients submitted to IVT. At 5 years, 32.9% of patients had an excellent outcome (95% confidence interval (CI) =25.5-43.3) and mortality was 43.9% (95%CI=36.1-51.7). Increasing age (odds ratio =0.93, 95% CI =0.90-0.97) and increasing National Institute of Health Stroke Scale (NIHSS) 24 h after thrombolysis (odds ratio =0.81, 95% CI =0.74-0.90) were independently associated with a lower likelihood of an excellent 5-year outcome. Age (hazards ratio =1.07, 95% CI =1.03-1.11) and excellent functional outcome 3 months after thrombolysis (hazards ratio =0.28, 95%CI=0.12-0.66) were independently associated with mortality during follow-up. CONCLUSIONS: One third of ischemic stroke patients have excellent 5-year outcome after IVT. Younger age, lower NIHSS 24 h after IVT, and excellent 3-month functional outcome are independent predictors of excellent 5-year outcome.
- Orolingual angioedema after thrombolysis is not associated with insular cortex ischemia on pre-thrombolysis CTPublication . Pinho, J; Alves, JN; Oliveira, L; Pereira, S; Barros, JN; Machado, C; Amorim, JM; Santos, AF; Ribeiro, M; Ferreira, COrolingual angioedema (OA) is a well known early complication of treatment with alteplase in ischemic stroke patients. Our aim was to study risk factors for OA in these patients, namely insular cortex ischemia.
- Pregnancy outcomes in Portuguese women with multiple sclerosis: The PREGNIMS studyPublication . Novo, A; Castelo, J; de Sousa, A; Amorim, I; Alves, JN; Calejo, M; Monteiro, A; Arenga, M; Shamasna, M; Vale, J; Sá, MJ; Palavra, FINTRODUCTION: Several questions about pregnancy in women with multiple sclerosis (MS) have been discussed, but clarification is still needed in some very practical issues. Portuguese data on this subject remain scattered and need to be analyzed in order to standardize clinical practice. OBJECTIVE: This study aimed to describe and analyze the impact of MS on pregnancy and perinatal health of children born to Portuguese mothers with the disease. MATERIAL AND METHODS: This is a multicenter, retrospective study of a cohort of Portuguese women with MS who were pregnant and who gave birth between 01/01/2011 and 31/12/2015. Demographic and clinical data related to maternal disease, pregnancy progression and events, childbirth and newborn health were collected. RESULTS: Ninety-seven women were recruited and 90 live births were evaluated. The mean maternal age at conception was 32.5 years, and 63.9% had no relapses in the previous year (98.0% had a relapsing-remitting MS and the EDSS score was ≤ 3 in 92.8% of the cases). Only 50.5% of the women had a preconception specific evaluation and 60 children were exposed to immunomodulatory therapies during pregnancy. Nineteen women had relapses during pregnancy. Childbirth was induced in 22.7% of the cases, and the caesarean section rate was 34%. Children exposed to immunomodulatory drugs during pregnancy had a lower birth length (p = 0.014), and there was also a trend toward lower birth weight (p = 0.054) in these newborns. Pre-conception EDSS score negatively correlated with the duration of pregnancy (r = -0.22; p = 0.029), weight (r = -0.23; p = 0.031) and cephalic perimeter at birth (r = -0.24; p = 0.033). There was no relationship between the occurrence of relapses or progression in EDSS score during pregnancy with any variables related to the newborn. CONCLUSIONS: In our cohort, it has been confirmed that MS has no negative effect on pregnancy or on children's perinatal health. However, the use of immunomodulatory drugs may have some impact on newborns' somatometric features.
- Sexual dysfunction in women with Parkinson's diseasePublication . Varanda, S; Ribeiro da Silva, J; Costa, AS; Amorim de Carvalho, C; Alves, JN; Rodrigues, M; Carneiro, GBACKGROUND: Sexual dysfunction in women with Parkinson's disease is poorly understood and research in this area is scarce. The objectives of this study were sexual function characterization in female Parkinson's disease patients, description of sexual dysfunctions, correlation with disease characteristics, and comparison with matched healthy controls. METHODS: Social and demographic data from consecutive female patients with Parkinson's disease and matched healthy controls were collected. The following instruments were used: UPDRS, the Hoehn and Yahr scale, the Beck Depression Inventory-II, the Female Sexual Function Index, and the Sexual Dysfunction Inventory. The only exclusion criterion was cognitive deterioration precluding comprehension of the study scope and its instruments. RESULTS: Of the 95 patients identified, 61 were included. Mean age was 66 years (range 40-89 years), and mean disease duration was seven years (range 1-18 years). Twenty-nine presented an akinetic-rigid syndrome, 25 tremoric disease, and, the remaining, a mixed type of disease. Mean "on" total/part III UPDRS scores were 46 ± 15.0 and 31 ± 8.9. Sexual dysfunction was present in 86.9% of patients and 79.0% of controls, according to the Female Sexual Function Index (p < .01), and in 57.4% of patients and 22.6% of controls, according to the Sexual Dysfunction Inventory (p < .001). Multivariate binary logistic regression identified age and depressive symptoms as positive predictors in the severity of sexual dysfunction. Disease duration, UPDRS part III score, Hoehn and Yahr stage, and antiparkinsonian medication did not show significant predictive value. CONCLUSIONS: Sexual dysfunction is more prevalent in women with Parkinson's disease than in controls and is predicted by older age and severity of depressive symptoms. © 2016 International Parkinson and Movement Disorder Society.
- Wake-up Stroke and Stroke within the Therapeutic Window for Thrombolysis Have Similar Clinical Severity, Imaging Characteristics, and OutcomePublication . Costa, R; Pinho, J; Alves, JN; Amorim, JM; Ribeiro, M; Ferreira, CBACKGROUND: Wake-up stroke (WUS) represents 25% of all ischemic strokes. There is conflicting evidence concerning clinical severity, imaging characteristics, and outcome when WUS is compared with stroke of known time of onset. Our aim was to compare WUS patients with patients with ischemic stroke within the therapeutic window (STW) for thrombolysis. METHODS: This is a retrospective hospital-based study of all consecutive patients hospitalized for acute ischemic stroke during 2013. Patients with STW, WUS, and WUS with computed tomography (CT) at 3 hours or less after awakening (WUS≤3h) were selected for the study. The methods used include a review of clinical records, an independent quantification of early signs of ischemia on admission CT scan, and determination of functional outcome on follow-up. RESULTS: Of 554 patients evaluated, 190 had STW, 113 had WUS (20.4%), and 25 had WUS≤3h. Among all WUS patients, 33.6% did not have any other formal contraindication for thrombolysis besides undetermined time of onset. WUS patients had demographic characteristics, vascular risk factors, and clinical severity similar to STW patients. Mild or absent early signs of ischemia on admission CT in WUS≤3h patients were similar to those in STW patients when adjusted for clinical severity (odds ratio [OR] = .50, 95% confidence interval [CI]=.17-1.47). Favorable prognosis in WUS≤3h was similar to STW when adjusted for age, clinical severity, and thrombolysis (OR = .53, 95% CI=.09-3.14). CONCLUSIONS: This study strengthens the evidence that clinical and early imaging characteristics of WUS patients are similar to those of patients with stroke who are eligible for thrombolysis based on the time window criteria, and patients with WUS do not have a worse short outcome.
