RESUMO

Hemodynamic management, specifically blood pressure, is essential to reduce mortality and preserve functional capacity. However, the literature is uncertain about the best blood pressure target to be adopted after performing mechanical thrombectomy in patients with acute ischemic stroke. Randomized clinical trials that compared blood pressure goals after mechanical thrombectomy were searched in the following databases: MEDLINE/PubMed, Embase, Scopus, Biomedcentral, and Cochrane Library. The last search was on September 19, 2023. The results obtained were used to construct network meta-analyses. A total of 1556 participants were enrolled from 4 randomized controlled trials (OPTIMAL-BP, ENCHANTED2/MT, BP-TARGET, BEST-II). The last article was not included in the network meta-analysis because it did not have common blood pressure targets. The outcomes compared were: mRS (modified Rankin scale), eTICI/mTICI scale scores, symptomatic and any intracerebral hemorrhage, post-intervention NIHSS, and post-intervention infarct volume. The outcomes using the mRS scale showed that better outcomes were reached with less intensive blood pressure targets when comparing < 120 mmHg vs. ≤ 180 mmHg, OR: 0.71 (95% CI 0.54 - 0.94), in the outcome of mRS 0-1. And for the mRS 0-2 outcome with comparisons < 120 mmHg vs. ≤ 180 mmHg, with OR: 0.59 (95% CI 0.44 - 0.77) and < 140 mmHg vs. ≤ 180 mmHg, with OR: 0.61 (95% CI 0.41 - 0.89). In patients with large vessel occlusion treated with mechanical thrombectomy and who achieved good reperfusion, intensive blood pressure lowering is not effective and might be harmful respect to non intensive blood pressure control in recanalized patients.

RESUMO

The efficacy and safety of dual antiplatelet therapy (DAPT) relative to intravenous (IV) alteplase in patients with acute minor ischemic stroke are insufficiently established. Therefore, we aimed to perform a meta-analysis to compare DAPT with IV alteplase in patients with acute minor stroke. MEDLINE, Embase, and Cochrane were searched for studies comparing DAPT with IV alteplase in patients with minor stroke. Functional and safety outcomes in 90 days were analyzed. Statistical analysis was performed using Rstudio 4.3.1. Subanalyses were performed restricted to non-disabling minor strokes and NIHSS score ≤ 3. PROSPERO (CRD42023440986). We included five studies with a total of 6,340 patients, of whom 4,050 (63.9%) received DAPT. The follow-up period for all included studies was 90 days. There was no significant difference for individual outcomes of mRS 0-1 (OR 1.26; 95% CI 0.85-1.89; p = 0.25), mRS 0-2 (OR 0.99; 95% CI 0.69-1.43; p = 0.97), or all-cause mortality (OR 0.80; 95% CI 0.20-3.13; p = 0.75) between groups. Symptomatic intracranial hemorrhage (sICH) was significantly lower (OR 0.11; 95% CI 0.003-0.36; p < 0.001) in patients treated with DAPT compared with IV alteplase. In terms of mRS 0-1 and mRS 0-2, we found no significant difference in both subgroup analyses. We found no statistically significant difference between DAPT and IV alteplase regarding functional outcome (mRS scores of 0-1 and 0-2) or all-cause mortality at 90 days in patients with minor ischemic stroke. Additionally, DAPT was associated with a significantly lower rate of sICH.

RESUMO

SUMMARY BACKGROUND: Cerebrovascular accident (or stroke) and ischemic heart disease are the the major causes of death in the world. It is estimated that about 85% of strokes are ischemic in origin. Reperfusion therapy in the acute phase of ischemic stroke with a recombinant human tissue plasminogen activator is effective, but some factors influence the success of this treatment. OBJECTIVE: The aim of this study was to evaluate clinical aspects and possible determinants for reperfusion after venous thrombolysis. METHODS: This is a retrospective, cross-sectional, observational study based on a review of hospital records of inpatients diagnosed with ischemic stroke treated with intravenous thrombolysis, the main outcome being reperfusion or not. RESULTS: Data from this study revealed a predominance of females in the group of reperfused patients and males in the non-reperfused group, both maintaining moderate severity on the National Institutes of Health Stroke Scale and admission without statistical significance (p>0.18). In addition, the mean admission severity score was 13.2 for the group of reperfused patients and 14.2 for those not reperfused, and the mean ejection fraction of both groups was within normal functionality, with a mean of 0.50 for reperfused patients and 0.62 for non-reperfused patients. CONCLUSION: We found an association between successful venous chemical thrombolysis reperfusion and lower mortality in patients with acute stroke.

RESUMO

The municipality of Salvador, situated in Brazil, distinguished itself as the epicenter of the emergence of microcephaly related to congenital manifestations of Zika syndrome. Despite the anticipated significant developmental setbacks in these children, research has indicated a varied range of outcomes, with certain instances even reflecting minimal developmental delay. Our objective was to pinpoint determinants that could forecast developmental anomalies in children diagnosed with microcephaly associated with congenital Zika syndrome (CZS). METHODOLOGY: A forward-looking clinical and neurodevelopmental examination was conducted focusing on neonates diagnosed with microcephaly with CZS, birthed between September 2015 and April 2016 at the Hospital Geral Roberto Santos, in Salvador city. That infants were monitored up to their third year by a multiprofessional team. Child development was assessed using the composite Bayley III score. Undertaken by two blinded experts, cranial CT scan analysis was performed during the neonate period for the detection of brain abnormalities and to quantify ventricle enlargement, measured by Evans' index (EI). RESULTS: Fifty newborns were evaluated with a median head circumference of 28 cm (interquartile range 27-31 cm). EI was associated with neurodevelopmental delay at three years and remained significant after adjustment for head circumference. A 0.1-point increase in EI was associated with a delay of 3.2 months in the receptive language (p = 0.016), 3.4 months in the expressive language (p = 0.016), 3.4 months in the cognitive (p = 0.016), 2.37 months in the gross motor (p = 0.026), and 3.1 months in the fine motor (p = 0.021) domains. CONCLUSIONS: EI predicted neurodevelopmental delay in all Bayley domains in children with microcephaly associated with CZS.

RESUMO

Over the last three decades, stroke care has undergone significant transformations mainly driven by the introduction of reperfusion therapy and the organization of systems of care. Patients receiving treatment through a well-structured stroke service have a much higher chance of favorable outcomes, thereby decreasing both disability and mortality. In this article, we reviewed the scientific evidence for stroke reperfusion therapy, including thrombolysis and thrombectomy, and its implementation in the public health system in Brazil.

RESUMO

Background: The frequency of antibodies in autoimmune encephalitis (AIE) may vary in different populations, however, data from developing countries are lacking. To describe the clinical profile of AIE in Brazil, and to evaluate seasonality and predictors of AIE in adult and pediatric patients. Methods: We evaluated patients with possible AIE from 17 centers of the Brazilian Autoimmune Encephalitis Network (BrAIN) between 2018 and 2022. CSF and serum were tested with TBAs and CBAs. Data on clinical presentation, complementary investigation, and treatment were compiled. Seasonality and predictors of AIE in adult and pediatric populations were analyzed. Results: Of the 564 patients, 145 (25.7%) were confirmed as seropositive, 69 (12.23%) were seronegative according to Graus, and 58% received immunotherapy. The median delay to diagnosis confirmation was 5.97 ± 10.3 months. No seasonality variation was observed after 55 months of enrolment. The following antibodies were found: anti-NMDAR (n=79, 54%), anti-MOG (n=14, 9%), anti-LGI1(n=12, 8%), anti-GAD (n=11, 7%), anti-GlyR (n=7, 4%), anti-Caspr2 (n=6, 4%), anti-AMPAR (n=4, 2%), anti-GABA-BR (n=4, 2%), anti-GABA-AR (n=2, 1%), anti-IgLON5 (n=1, 1%), and others (n=5, 3%). Predictors of seropositive AIE in the pediatric population (n=42) were decreased level of consciousness (p=0.04), and chorea (p=0.002). Among adults (n=103), predictors of seropositive AIE were movement disorders (p=0.0001), seizures (p=0.0001), autonomic instability (p=0.026), and memory impairment (p=0.001). Conclusion: Most common antibodies in Brazilian patients are anti-NMDAR, followed by anti-MOG and anti-LGI1. Only 26% of the possible AIE patients harbor antibodies, and 12% were seronegative AIE. Patients had a 6-month delay in diagnosis and no seasonality was found. Findings highlight the barriers to treating AIE in developing countries and indicate an opportunity for cost-effect analysis. In this scenario, some clinical manifestations help predict seropositive AIE such as decreased level of consciousness, chorea, and dystonia among children, and movement disorders and memory impairment among adults.

RESUMO

INTRODUCTION: Deficits in respiratory function of patients with Parkinson's disease contribute to aspiration pneumonia, one of the main causes of mortality in this population. The aim of this study was to evaluate the effects of functional training, bicycle exercise, and exergaming on respiratory function of elderly with Parkinson's disease. METHODS: A randomized clinical trial with single blinding was conducted in a public reference outpatient clinic for the elderly. The participants were randomly assigned to three groups. Group 1 was submitted to functional training (n = 18); group 2 performed bicycle exercise (n = 20), and group 3 trained with Kinect Adventures exergames (n = 20). The sessions performed lasted 8 weeks with a frequency of three 50-min sessions per week. The primary outcome was the forced expiratory volume in the first second; and the secondary outcomes were forced vital capacity, peak expiratory flow, and maximum inspiratory and expiratory pressures. RESULTS: The interventions performed did not improve the forced expiratory volume in the first second, forced vital capacity, and peak expiratory flow. However, group 2 improved (p = 0.03) maximum expiratory pressure (from 65.5cmH2O to 73.1cmH2O) (effect size 0.47), and group 3 increased (p = 0.03) maximum inspiratory pressure (from -61.3cmH2O to -71.6cmH2O) (effect size 0.53). CONCLUSIONS: No effect was found on lung volume, forced respiratory flow and capacity of the participants with Parkinson's disease submitted to three different modalities of motor training. However, bicycle exercise and exergaming have improved expiratory and inspiratory muscle strength, respectively. NCT02622737.

RESUMO

PURPOSE: To verify the psychometric properties of the Brazilian-Portuguese version of the Falls Behavioral (FaB-Brazil) Scale in Parkinson's disease (PD). MATERIAL AND METHODS: Participants (n = 96) were assessed by disease-specific, self-report and functional mobility measures. Internal consistency of the FaB-Brazil scale was evaluated using Cronbach's alpha and inter-rater and test-retest reliability using intraclass correlation coefficients (ICC). The standard error of measurement (SEM), minimal detectable change (MDC), ceiling and floor effects, and convergent and discriminative validity were evaluated. RESULTS: Internal consistency was moderate (α = 0.77). Excellent inter-rater (ICC = 0.90; p < 0.001) and test-retest (ICC = 0.91; p < 0.001) reliability were found. The SEM was 0.20 and MDC was 0.38. Ceiling and floor effects were not found. Convergent validity was established by the positive correlations between the FaB-Brazil scale and age, modified Hoehn and Yahr, PD duration, Movement Disorders Society-Unified Parkinson's Disease Rating Scale, Motor Aspects of Experiences of Daily Living, Timed Up & Go and 8-item Parkinson's Disease Questionnaire, and negative correlations between the FaB-Brazil scale and community mobility, Schwab & England, and Activities-specific Balance Confidence scale. Females showed greater protective behaviors than males; recurrent fallers showed greater protective behaviors than non-recurrent fallers (p < 0.05). CONCLUSIONS: The FaB-Brazil scale is reliable and valid for assessing people with PD.


Fall-related behaviors should be part of the fall risk assessment of community-dwelling people with Parkinson's disease.The Brazilian-Portuguese version of the Fall Behavioral (FaB-Brazil) Scale is reliable and valid for assessing everyday behaviors and actions related to falling in community-dwelling people with Parkinson's disease.The FaB-Brazil scale may be used to tailor individualized fall prevention programs.

RESUMO

Abstract Background Atrial fibrillation (AF) is a potent risk factor for stroke. The presence of competing etiologies can modify disease outcomes and demand different treatment strategies. Objective The primary purpose of the study was to examine the differences in outcomes for patients with AF admitted with a recurrent stroke, stratified according to the presumed etiology of the stroke. Methods We analyzed AF patients admitted for a recurrent ischemic stroke in an academic comprehensive stroke center. Recurrent strokes were categorized as "Cardioembolic", meaning AF without any competing mechanism, versus "Undetermined" etiology due to competing mechanisms. We used logistic regression to test the association between recurrent stroke etiology and favorable outcome (discharge home), after accounting for important covariates. Results We included 230 patients, with a mean age 76.9 (SD ± 11.3), 52.2% male, median National Institute of Health Stroke Scale (NIHSS) score of 7 (IQR 2-16). Patients with cardioembolic stroke (65.2%) had higher median NIHSS 8.5 (3-18) versus 3 (1-8) and were more likely to be treated with reperfusion therapies. The favorable outcome was reached by 64 patients (27.8%), and in-hospital mortality was 15.2% overall. After adjustment, there was no difference in outcome between patients with cardioembolic versus undetermined stroke etiology (odds ratio for discharge home: 1.41; 95% CI: 0.65-3.15). Conclusions In this single-center sample of AF patients with history of stroke, there was no difference in discharge outcomes between those with cardioembolic and those with undetermined stroke etiology. This question warrants examination in larger samples to better understand the importance of the stroke mechanism and secondary prophylaxis.

RESUMO

BACKGROUND: Obstructive sleep apnea (OSA) is the most common form of sleep-disordered breathing in cerebrovascular diseases, requiring a multidisciplinary approach. There are few studies evaluating the effects of inspiratory muscle training (IMT) in individuals with OSA and the findings regarding the possible effect on apnea hypopnea index (AHI) reduction are controversial. OBJECTIVE: This protocol for a randomized clinical trial will assess the effects of IMT on the severity of obstructive sleep apnea, sleep quality, and daytime sleepiness in individuals after stroke participating in a rehabilitation program. METHODS: This study will be a randomized controlled trial with blinded assessors. Forty individuals after stroke will randomized to two groups. For 5 weeks, both groups will participate in the rehabilitation program activities, including aerobic exercise, resistance training, and educational class when they will receive guidance on the behavioral management of OSA. The experimental group will also perform high-intensity IMT 5 times a week, for 5 weeks, consisting initially of five sets of five repetitions achieving 75% of the maximal inspiratory pressure, increasing one set each week, totaling nine sets at the end of training. The primary outcome will be the severity of OSA measured as AHI at 5 weeks. Secondary outcomes will include sleep quality measured by the Pittsburgh Sleep Quality Index (PSQI) and daytime sleepiness measured by Epworth Sleepiness Scale (ESS). Outcomes will be collected by a researcher blinded to group allocation at baseline (week 0), after intervention (week 5), and 1 month beyond intervention (week 9). TRIAL REGISTRATION: Clinical Trials Register: NCT05135494.

RESUMO

PURPOSE: To develop and cross-culturally adapt a Brazilian-Portuguese version of the Falls Behavioral Scale (FaB-Brazil) and to verify its psychometric properties. MATERIAL AND METHODS: The translation and cross-cultural adaptation process of the scale followed standard guidelines. The FaB-Brazil scale was applied to 93 community-dwelling older people. Cronbach's alpha was calculated to evaluate internal consistency and the intraclass correlation coefficient (ICC) to evaluate interrater and test-retest reliability. The standard error of measurement (SEM), minimal detectable change (MDC), ceiling and floor effects, convergent and discriminative validity were evaluated. A significance level of .05 was set for statistical analyses. RESULTS: Internal consistency was moderate (α = 0.73). An excellent inter-rater (ICC = 0.93; p < 0.001) and a good test-retest (ICC = 0.79; p < 0.001) reliability were found. The SEM was 0.27 and MDC was 0.53. Neither ceiling nor floor effects were found. Convergent validity was established by the positive correlations between the FaB-Brazil scale, age, and functional mobility, and by the negative correlations between the FaB-Brazil scale and balance confidence, community mobility and EuroQol-5D (p < 0.05). No significant differences were found between males and females and between non-fallers and fallers. CONCLUSIONS: Our results offer evidence for the reliability and validity of the FaB-Brazil scale for community-dwelling older people.Implications for RehabilitationFall-related behaviors should be part of the fall risk assessment of community-dwelling older people.The Brazilian-Portuguese version of the Falls Behavioral Scale (FaB-Brazil) is reliable and valid for assessing fall-related behaviors in community-dwelling older people.The FaB-Brazil scale may be used to raise awareness about potential fall hazards and to guide fall prevention programs.

RESUMO

Abstract Background Refractory hypertension (RfH) is a severe phenotype of resistant hypertension (RH) linked to higher risk of stroke and other adverse cardiovascular events, but knowledge about it is still lacking. Objectives To evaluate the association between RfH and stroke. Methods We conducted a cross-sectional study in a referral clinic for patients with severe hypertension in the period from 2018 to 2020. RH was defined as uncontrolled blood pressure (BP) despite the use of 3 antihypertensive agents, including a diuretic, or the use of ≥ 4 agents regardless of BP control. RfH was defined as lack of BP control despite use of ≥ 5 antihypertensive agents. Individuals were classified as RfH or RH, and multivariate logistic regression models were constructed to examine the association between RfH and stroke. Results We evaluated a total of 137 patients; 81% were female, and 93,3% were Black or multiracial. The mean age was 64.4 years. Stroke was more prevalent in the RfH group (35.7%), in comparison to the RH group (12.8%) (p value = 0.01). Unadjusted odds ratio (OR) and 95% confidence interval (CI) for factors associated with stroke were RfH (OR 3.77; 95% CI 1.45 to 9.80), systolic BP (OR 1.02; 95% CI 1.002 to 1.04) and diastolic BP (OR 1.03; 95% CI 1.001 to 1.06). Adjusted OR for factors associated with stroke were RfH (OR 3.55; 95% CI 1.02 to 12.42), systolic BP (OR 1.02; 95% CI 0.99 to 1.05) and diastolic BP (OR 1.01; 95% CI 0.96 to 1.06). Conclusion RfH was associated with higher prevalence of stroke. Efforts are required to better understand this association to prevent adverse cardiovascular outcomes in these patients.

RESUMO

Mucosal leishmaniasis (ML) is a severe form of tegumentary leishmaniasis associated with a persistent inflammatory response. High levels of TNF, IFN-γ, CXCL9 and CXCL10 are found in ML patients, and the association of pentoxifylline with antimony is more effective in decreasing the healing time in ML patients when compared to antimony alone. The present study aimed to investigate the existence of a correlation between cytokine and chemokine production and ML severity and evaluate the potential value of cytokine and chemokine production as marker of therapeutic response in ML patients. This prospective study included 86 subjects in an area of endemic Leishmania braziliensis transmission. Patients diagnosed with ML were classified into clinical stages ranging from I to V according to disease severity. TNF, IFN-γ, CXCL9 and CXCL10 levels were quantified in the supernatant of the mononuclear cell cultures by ELISA before and after treatment with antimony alone or antimony plus pentoxifylline. The median TNF level in the group with mild disease (Stages I-II) was 1064 pg/mL (142-3738 pg/mL), while, in the group with moderate or severe disease (Stages III-V), it was 1941 pg/mL (529-5294 pg/mL) (p = 0.008). A direct correlation was observed between ML clinical severity and levels of TNF production (r = 0.44, p = 0.007). Patients who were treated with antimony and pentoxifylline healed significantly faster than those treated with antimony alone (52 vs. 77 days, hazard ratio = 0.60; 95% confidence interval = 0.38-0.95, p = 0.013). Therapeutic failure was higher in the group that received antimony alone (25% vs. 7%; p = 0.041). There was a significant decrease in CXCL9 after therapy of ML in both groups (p = 0.013; p = 0.043). TNF levels are associated with the severity of mucosal diseases, and pentoxifylline associated with antimony should be the recommended therapy for ML in countries where liposomal amphotericin B is not available.

RESUMO

BACKGROUND: Aphasia, the most common language disorder secondary to stroke, has been associated with increased mortality, longer hospitalization and rehabilitation times, worse performance in daily activities, increased financial burden, and short- and long-term complications. Aphasia can negatively impact functional communication skills, including social networks, social activities, relationships with other people and social support. OBJECTIVE: To evaluate patients with poststroke aphasia in their respective residences to investigate potential predictors of functional communication. METHODS: The prospective cohort included patients with poststroke aphasia aged 18 years or older who resided in the city of Salvador, Northeastern Brazil. Following discharge from the Stroke Unit (SU), the individuals themselves, or their guardians, were contacted by telephone to schedule a home visit no less than three months after discharge. At baseline, sociodemographic and clinical data were collected, in addition to the scores on the National Institutes of Health Stroke Scale (NIHSS) and modified Barthel Index (mBI). The American Speech-Language-Hearing Association Functional Assessment of Communication Skills for Adults (ASHA FACS) was applied at the patients' homes. Multivariate linear regression was employed using the total score on the ASHA FACS as the outcome of interest. RESULTS: A multivariate analysis of the associated factors identified using the linear regression revealed that only functional capacity (as assessed by the mBI) upon discharge from the SU remained as an independent predictor of functional communication performance (ß = 0.042; 95% confidence interval [95%CI] = 0.013-0.071; p = 0.002). CONCLUSION: The functional capacity to perform daily activities, evaluated upon discharge from a stroke unit, was identified as a potential predictor of functional communication performance, regardless of the time elapsed after the stroke.


ANTECEDENTES: A afasia, distúrbio de linguagem mais comum secundário ao acidente vascular cerebral (AVC), está associada ao aumento da mortalidade, a um maior tempo de internação e reabilitação, ao pior desempenho nas atividades diárias, ao aumento da carga financeira, e às complicações de curto e longo prazos. Pode impactar negativamente as habilidades de comunicação funcional, incluindo atividades sociais, relacionamento com outras pessoas, e o apoio social. OBJETIVO: Avaliar pacientes com afasia pós-AVC em suas respectivas residências para investigar potenciais preditores de comunicação funcional. MéTODOS: A coorte prospectiva incluiu pacientes com afasia pós-AVC com 18 anos de idade ou mais, residentes em Salvador, Brasil. Após a alta da Unidade de AVC (UAVC), os próprios indivíduos, ou seus responsáveis, foram contatados por telefone para agendamento de visita domiciliar no mínimo três meses após a alta. Inicialmente, foram coletados dados sociodemográficos e clínicos, além das pontuações na National Institutes of Health Stroke Scale (NIHSS) e no Índice de Barthel modificado (IBM). O American Speech-Language-Hearing Association Functional Assessment of Communication Skills for Adults (ASHA FACS) foi aplicado no domicílio dos pacientes. A regressão linear multivariada foi empregada usando a pontuação total no ASHA FACS como o desfecho de interesse. RESULTADOS: A análise multivariada por meio de regressão linear revelou que apenas a capacidade funcional avaliada na alta da UAVC permaneceu como preditor independente do desempenho da comunicação funcional (ß = 0,042; intervalo de confiança de 95% [IC95%] = 0,013­0,071; p = 0,002). CONCLUSãO: A capacidade funcional para realizar as atividades diárias, avaliada na alta hospitalar, foi identificada como potencial preditor do desempenho da comunicação funcional, independente do tempo desde o AVC.

RESUMO

ABSTRACT. Motor fluctuations in Parkinson's disease (PD) are a frequent long-term complication. Knowledge is limited on the prevalence and incidence of non-motor symptoms (NMS) fluctuations, especially in Brazil. Objective: The objective of this study was to verify the frequency of NMS fluctuations and its relationship with other aspects of PD in patients followed at an outpatient movement disorders clinic. Methods: This is a cross-sectional study in which patients were evaluated for the presence of both types of fluctuations using the Wearing Off Questionnaire (WOQ-19). Results: A total of 37 patients (11 women and 26 men) were participated in this study, and the frequency of NMS fluctuations was 54.1% (90.9% in women and 38.5% in men). Anxiety was the most frequent non-motor fluctuation (35.1%). The highest percentage of NMS fluctuations (70%) was found in the group in which disease duration was more than 6 years. Most patients with motor fluctuations also had NMS fluctuations (66.7%). No patient presented with isolated NMS fluctuations. Conclusions: This study showed that, in the study population, approximately half of the patients had NMS fluctuations, with a higher frequency among women. A higher frequency was present in patients with earlier age of diagnosis, longer duration, and greater severity of disease. These findings point to the importance of recognizing the fluctuations of NMS in the study population, since these may not be spontaneously mentioned by the patient, who is remaining unnoticed, undiagnosed, and not treated by the neurologist, representing a significant aggravating factor in the patient's quality of life.


RESUMO. A flutuação dos sintomas na doença de Parkinson é uma complicação frequente em longo prazo. Pouco é conhecido sobre a prevalência e a incidência de flutuações de sintomas não motores (SNM), principalmente na população brasileira. Objetivo: Verificar a frequência das flutuações dos SNM e sua relação com outros aspectos da doença de Parkinson em pacientes acompanhados em ambulatório de movimentos anormais do Hospital das Clínicas de Salvador, Bahia. Métodos: Trata-se de um estudo de corte transversal, no qual os pacientes foram avaliados quanto à presença de flutuações utilizando-se o Wearing-Off Questionnaire (WOQ-19). Resultados: O total de 37 pacientes (11 mulheres e 26 homens) participou do estudo. A frequência de flutuações dos SNM foi de 54,1% (90,9% no sexo feminino e 38,5% no sexo masculino). Ansiedade foi a flutuação não motora mais frequente (35,1%). O maior percentual de flutuações dos SNM (70%) encontrou-se no grupo cujo tempo de doença estava acima de seis anos. A maioria dos pacientes com flutuações motoras teve também flutuações dos SNM (66,7%). Nenhum paciente apresentou apenas flutuação de SNM. Conclusões: O presente estudo mostrou que, na população estudada, aproximadamente metade dos pacientes apresentaram flutuações dos SNM, sendo essa frequência maior no sexo feminino. Estes achados apontam para a importância do reconhecimento das flutuações dos SNM na população estudada, já que elas podem não ser espontaneamente citadas pelo paciente, passando despercebidas, não sendo diagnosticadas nem tratadas pelo neurologista e constituindo-se em agravante não desprezível na qualidade de vida dos pacientes.

RESUMO

OBJECTIVES: To describe the differences in clinical presentation and relative disease burden of congenital Zika syndrome (CZS)-associated microcephaly at 2 large hospitals in Salvador, Brazil that serve patients of different socioeconomic status (SES). METHODS: Clinical and serologic data were collected prospectively from pregnant women and their infants, who delivered at 2 study centers during the 2015-2016 Zika virus (ZIKV) epidemic in Salvador, Brazil. RESULTS: Pregnant women from Salvador, Brazil delivering in a low SES hospital had 3 times higher ZIKV exposure rate than women at a high SES hospital. However, different SES hospitals had similar prevalence of infants with CZS-associated microcephaly (10% vs 6%, p = 0.16) after controlling for ZIKV exposure in their mothers. CONCLUSIONS: Our study supports the positive association between low SES, high maternal ZIKV exposure, and high rates of CZS-associated microcephaly.
