ABSTRACT Introduction: Fabry disease (FD) is an inborn error of metabolism characterized by α-galactosidase A deficiency. The primary objective was to evaluate the genetic and phenotypic profile of Fabry disease in hemodialysis. Methods: Observational cohort study to determine the incidence of genetic variations and phenotypic changes for FD in hemodialysis patients in the Paraiba Valley and Eastern São Paulo. Genetic testing for the GLA gene was performed for men and women over 12 years of age at the hemodialysis clinics between January 2016 and December 2019 as a screening protocol. Results: The cases came from screening exams of the index case among patients with chronic kidney disease, resulting in 17 families and totaling 82 patients under study. The classification of the most prevalent variant was that of uncertain significance (54%), followed by the pathogenic variant (46%). Five patients in two families were described with two types of variants not previously described in the literature, with pathogenic behavior. Comparing the types of variants, the presence of a pathogenic variant was associated with higher levels of lysoGB3, lower values for alpha-GAL activity and higher frequency of symptoms related to FD. Conclusion: We characterized an extensive population of patients with FD variants with rich genetic, clinical and biomarker details. We believe that this study can help to better characterize the Brazilian population with FD and the most frequent types of variants.

RESUMO Introdução: A doença de Fabry (DF) é um erro inato do metabolismo caracterizado pela deficiência da enzima α-galactosidase A. O objetivo primário foi avaliar o perfil genético e fenotípico da doença de Fabry em hemodiálise. Métodos: Estudo de coorte observacional para determinar a incidência de variações genéticas e alterações fenotípicas para DF em pacientes em hemodiálise no Vale do Paraíba e Zona Leste de São Paulo. O teste genético para o gene GLA foi realizado para homens e mulheres em todos os pacientes das clínicas de hemodiálise maiores de 12 anos entre janeiro de 2016 a dezembro de 2019 como protocolo de rastreio. Resultados: Os casos foram provenientes de exames de triagem do caso índice entre pacientes portadores de doença renal crônica, resultando em 17 famílias e totalizando 82 pacientes em estudo. A classificação da variante mais prevalente foi a de significado incerto (54%), seguida da variante patogênica (46%). Foram descritos 5 pacientes em duas famílias com dois tipos de variantes ainda não previamente descritos na literatura com comportamento patogênico. Na comparação entre os tipos de variantes, a presença de variante patogênica foi associada a maiores níveis de lysoGB3, menores valores da atividade da alfa-GAL e maior frequência de sintomas relativos à DF. Conclusão: Caracterizamos uma extensa população de pacientes com variantes para DF com riqueza de detalhes de genética, clínica e de biomarcadores. Acreditamos que este estudo possa auxiliar na melhor caracterização da população brasileira com DF e nos tipos mais frequentes de variantes.

ABSTRACT Objective: To determine the prevalence and factors associated with the physical rehabilitation of critically ill children in Brazilian pediatric intensive care units. Methods: A 2-day, cross-sectional, multicenter point prevalence study comprising 27 pediatric intensive care units (out of 738) was conducted in Brazil in April and June 2019. This Brazilian study was part of a large multinational study called Prevalence of Acute Rehabilitation for Kids in the PICU (PARK-PICU). The primary outcome was the prevalence of mobility provided by physical therapy or occupational therapy. Clinical data on patient mobility, potential mobility safety events, and mobilization barriers were prospectively collected in patients admitted for ≥ 72 hours. Results: Children under the age of 3 years comprised 68% of the patient population. The prevalence of therapist-provided mobility was 74%, or 277 out of the 375 patient-days. Out-of-bed mobility was most positively associated with family presence (adjusted odds ratios 3.31;95%CI 1.70 - 6.43) and most negatively associated with arterial lines (adjusted odds ratios 0.16; 95%CI 0.05 - 0.57). Barriers to mobilization were reported on 27% of patient-days, the most common being lack of physician order (n = 18). Potential safety events occurred in 3% of all mobilization events. Conclusion: Therapist-provided mobility in Brazilian pediatric intensive care units is frequent. Family presence was high and positively associated with out-of-bed mobility. The presence of physiotherapists 24 hours a day in Brazilian pediatric intensive care units may have a substantial impact on the mobilization of critically ill children.

RESUMO Objetivo: Determinar a prevalência e os fatores associados à reabilitação física de crianças em estado grave em unidades de terapia intensiva pediátrica brasileiras. Métodos: Realizou-se um estudo de prevalência pontual multicêntrico, transversal, de 2 dias, abrangendo 27 unidades de terapia intensiva pediátrica (do total de 738) no Brasil em abril e junho de 2019. Este estudo brasileiro fez parte de um grande estudo multinacional chamado Prevalence of Acute Rehabilitation for Kids in the PICU (PARK-PICU). O desfecho primário foi a prevalência de mobilidade proporcionada pela fisioterapia ou pela terapia ocupacional. Foram coletados prospectivamente dados clínicos sobre a mobilidade do paciente, possíveis eventos de segurança de mobilidade e barreiras de mobilização em pacientes admitidos por ≥ 72 horas. Resultados: As crianças com idade inferior a 3 anos eram 68% da população de pacientes. A prevalência de mobilidade fornecida pelo terapeuta foi de 74%, ou 277 dos 375 pacientes-dia. A mobilidade para fora do leito foi mais positivamente associada à presença de familiares (razão de chance ajustada de 3,31; IC95% 1,70 - 6,43) e mais negativamente associada às linhas arteriais (razão de chance ajustada de 0,16; IC95% 0,05 - 0,57). Foram relatadas barreiras à mobilização em 27% dos pacientes-dia, sendo a mais comum a falta de prescrição médica (n = 18). Registaram-se eventuais eventos de segurança em 3% de todos os eventos de mobilização. Conclusão: A mobilidade proporcionada pelo terapeuta nas unidades de terapia intensiva pediátrica brasileiras é frequente. A presença de familiares foi alta e positivamente associada à mobilidade para fora do leito. A presença de fisioterapeutas 24 horas por dia nas unidades de terapia intensiva pediátrica brasileiras pode exercer papel importante na mobilização de crianças em estado grave.

ABSTRACT Introduction To evaluate the possible effects of the coronavirus disease 2019 (COVID-19) pandemic on the oncologic results of patients with prostate cancer regarding clinical staging, presence of adverse pathological outcomes, and perioperative complications. Materials and methods This retrospective study included patients who underwent radical prostatectomy. The time between biopsy and surgery, staging tests, final histopathological evaluation after surgery, lymphadenectomy rate, postoperative complications, and prostatic specific antigen (PSA) levels (initial and 30 days after surgery) were analyzed and compared in a group of patients before and during the pandemic period. Results We included 226 patients: 88 in the pre-pandemic period and 138 during the pandemic period. There was no statistically significant difference in mean age, body mass index, ASA, pathological locally advanced disease, the proportion of patients who underwent lymphadenectomy, and ISUP grade in the biopsy between the groups. Positive surgical margins, prostatic extracapsular extension, and PSA levels at 30 days were also similar between the groups. The mean time between medical consultation and surgery was longer in the pandemic period than in the pre-pandemic (124 vs. 107 days, p<0.001), and the mean time between biopsy and medical consultation (69.5 days vs. 114 days, p<0.001) and between biopsy and surgery (198.5 days vs. 228 days, p=0.013) was shorter during the pandemic. The incidence of severe early and late perioperative complications was similar between the periods. Conclusions There was no delay between diagnosis and treatment at our institution during the COVID-19 pandemic period. No worsening of the prostate cancer features was observed.

Abstract Objective To understand the impact of the coronavirus disease 2019 pandemic on in vitro fertilization (IVF) clinical pregnancy rates and analyze factors that may have influenced their outcome. Methods This was a retrospective observational study conducted at a tertiary-care Brazilian fertility center. All fresh IVF and embryo warming cycles performed from March 11 to December 31, 2018–2021 were analyzed, and their data were used to calculate fertilization, embryo cleavage, cycle cancellation, embryo transfer (ET), and clinical pregnancy rates. Statistical tests were used to evaluate the alterations found. Logistic regression models were used to explore the association of the categorical variables with the observed clinical pregnancy rates. Data from 2018 and 2019 (prepandemic) and 2020 and 2021 (pandemic) were grouped. Results A total of 756 cycles were analyzed (n = 360 prepandemic and n = 396 pandemic). The age group of the patients, fertilization rates, and cleavage rates did not have significant differences (p > 0.05). There was a reduction in the percentage of fresh IVF and an increase in embryo warming cycles (p = 0.005) during the pandemic. There was also an increase in fresh cycle cancellations (p < 0.001) and a reduction in ET rates (p < 0.001). The pandemic had a negative impact on clinical pregnancy rates (p < 0.001) especially due to the increase in fresh cycle cancellations (p < 0.001). Conclusion Embryo warming cycles with subsequent frozen-thawed ET were presented as a viable alternative to continue assisted reproductive treatments against pandemic restrictions on fresh cycles, ensuring clinical pregnancy, albeit at a lower rate than that of the prepandemic period.

Resumo Objetivo Compreender os impactos da pandemia de COVID-19 nas taxas de gravidez clínica em fertilização in vitro (FIV) e analisar fatores que possam ter influenciado seu resultado. Métodos Foi realizado um estudo observacional retrospectivo em um centro brasileiro de reprodução assistida. Todos os ciclos de FIV com embriões frescos e descongelados realizados entre 11 de março e 31 de dezembro, 2018-2021 foram analisados, e seus dados utilizados para cálculo das taxas de fertilização, clivagem embrionária, cancelamento de ciclos, transferência de embriões (TE) e gravidez clínica. Testes estatísticos avaliaram significância das alterações encontradas e modelos de regressão logística exploraram associação das variáveis categóricas estudadas com as taxas de gravidez clínica observadas. Os dados de 2018 e 2019 (pré-pandemia) e 2020 e 2021 (pandemia) foram agrupados. Resultados Foram analisados um total de 756 ciclos (n = 360 na pré-pandemia e n = 396 na pandemia). A faixa etária das pacientes e as taxas de fertilização e de clivagem não tiveram alterações significativas (p > 0,05). Na pandemia, houve redução da porcentagem de ciclos de FIV com embriões frescos e aumento dos com descongelamento (p = 0,005). Também foi notado aumento das taxas de cancelamentos de ciclos com embriões frescos (p < 0,001) e redução do número de TEs (p < 0,001). A pandemia exerceu impacto negativo na taxa de gravidez clínica (p < 0,001), especialmente devido ao aumento de cancelamentos dos ciclos a fresco (p < 0,001). Conclusão Frente às limitações pandêmicas impostas aos ciclos com embriões frescos, os ciclos de descongelamento de embriões se apresentaram como alternativa viável à continuidade dos ciclos de FIV, garantindo gravidez clínica ainda que em taxas inferiores às do período pré-pandêmico.

Abstract Historically, phenol/croton oil deep chemical peeling has been very effective and has generated excellent results compared to other formulas used in dermatological clinics. However, it can cause serious side effects in patients sensitive to phenol. Therefore, this study aimed to develop a liquid crystalline structure containing croton oil (without phenol) as well as to evaluate the physical characteristics and cytotoxicity of this new system. Rational proportions of the croton oil, purified water, and polyethylene glycol hexadecyl ether were designed through a partial phase diagram to obtain 26 formulations. After macroscopic analysis and polarized light microscopy evaluation, formulations with lamellar liquid crystalline phase (4 samples) were identified and chosen to determine pH, size, polydispersion index (PDI), zeta potential, and rheological behavior. After 48 hours, three samples presented phase separation. Formulation 8 remained stable, but hydroxyethyl cellulose (HEC, 0.5%, w/w) was added to the aqueous phase, to prevent coalescence. Sample 8A exhibited a pH compatible with the skin, nanometric size, narrow PDI, negative zeta potential, and stability throughout the study period. The addition of HEC improved the organization of the system, making the formulation more stable. The oil, fractions of the oil, and the sample exhibited increasing cytotoxicity, respectively. This result could be attributed to the fractionation process of the vegetal matrix, and the surfactant present in the formulation increased the cell membrane permeability. The proposed approach successfully achieved a physically stable liquid crystal system containing croton oil.

ABSTRACT: Thoracoscopy is replacing open lung biopsies because it is less invasive, usually the technique is done using three portals and intracorporeal suture technique. This study described the feasibility and efficacy of a novel pre tied loop ligature and to propose a thoracoscopic access strategy with two portals to perform lung biopsy in patients under 5 kg. Ten rabbits were positioned in dorsal recumbency. Total thoracoscopic lung biopsy was performed using a combined transdiaphragmatic approach and a right intercostal approach. A pre tied loop ligature was placed to perform a caudal lung lobe biopsy. Insufflation of the thoracic cavity was not performed. The total surgery time was 41.4 ± 14.5 min. The procedure was carried out free of complications that prevented slippage or tightening the knot or that made it come loose after the lung biopsy; there was no serious complication during the surgical procedure. The samples obtained averaged 1x0.64x0.45 cm (Length, Width, Depth) and were considered satisfactory according to the histopathologic evaluation. Thorax radiographs taken before and after the surgeries were compared and showed no pneumothorax or hemothorax. Necropsy confirmed no knot failure occurred at the biopsy site. The use of the novel pre tied loop ligature is a safe and effective technique, avoiding problems with the limited size of the thoracic cavity in small patients.

RESUMO: A toracoscopia está substituindo as biópsias pulmonares abertas por ser menos invasiva. Usualmente a técnica é feita utilizando três portais e ligaduras feitas intra corporalmente. O objetivo deste estudo foi descrever a viabilidade e eficácia de uma nova ligadura com alça pré-amarrada e propor uma estratégia de acesso toracoscópico com dois portais para realizar biópsia pulmonar em pacientes com menos de 5kg. Dez coelhos foram posicionados em decúbito dorsal. A biópsia pulmonar por toracoscopia total foi feita pela abordagem combinada transdiafragmática e abordagem intercostal direita. Uma nova ligadura pré-amarrada foi colocada para realizar uma biópsia do lobo pulmonar caudal. Não foi realizada insuflação da cavidade torácica. O tempo total de cirurgia foi de 41,4 ± 14,5 min. Os procedimentos foram realizados sem complicações que impedissem o escorregamento ou aperto do nó ou que o soltassem após a biópsia pulmonar; não houve nenhuma intercorrência grave durante o procedimento cirúrgico. As amostras coletadas tinham tamanho médio 1x0,64x0,45 cm e foram consideradas satisfatórias de acordo com a avaliação histopatológica. As radiografias de tórax feitas antes e depois das cirurgias foram comparadas e não mostraram pneumotórax ou hemotórax. A necropsia confirmou que não ocorreu falha do nó no local da biópsia. Conclui-se que uso da nova ligadura com alça pré-amarrada é uma técnica segura e eficaz, evitando problemas com o tamanho limitado da cavidade torácica em pacientes pequenos.

ABSTRACT Purpose: This study compared, through biomechanical evaluation under ventral flexion load, four surgical techniques for ventral stabilization of the atlantoaxial joint in dogs. Methods: In total, 28 identical atlantoaxial joint models were created by digital printing from computed tomography images of a dog, and the specimens were divided into four groups of seven. In each group, a different technique for ventral stabilization of the atlantoaxial joint was performed: transarticular lag screws, polyaxial screws, multiple screws and bone cement (polymethylmethacrylate–PMMA), and atlantoaxial plate. After the stabilization technique, biomechanical evaluation was performed under ventral flexion load, both with a predefined constant load and with a gradually increasing load until stabilization failure. Results: All specimens, regardless of stabilization technique, were able to support the predefined load without failing. However, the PMMA method provided significant more rigidity (p ≤ 0.05) and also best resisted the gradual increase in load, supporting a significantly higher maximum force (p ≤ 0.05). There was no statistical difference in flexural strength between the transarticular lag screws and plate groups. The polyaxial screws method was significantly less resistant to loading (p ≤ 0.05) than the other groups. Conclusions: The PMMA technique had biomechanical advantages in ventral atlantoaxial stabilization over the other evaluated methods.

ABSTRACT The objective of this study was to evaluate the relationships between preovulatory follicle (POF) and corpus luteum (CL) diameters, and POF and CL vascular perfusion with progesterone production, ovulation, and pregnancy in Nellore cows subjected to timed artificial insemination (TAI). Nellore cows (n = 201) were subjected to ovulation synchronization and later to ultrasound evaluation of POF and CL at the time of insemination (D0) and seven days later (D7), respectively. Females were divided into three categories according to the POF diameter assessed at the time of insemination: small (SF), medium (MF), and large (LF) follicles. The LF group had a greater number and intensity of pixels in the POF ultrasound exam compared with the SF group. The CL flow intensity and progesterone concentration were also higher in the LF group. The SF group showed lower flow intensity and lower ovulation rate compared with the others. When non-pregnant females were compared to pregnant ones, no difference was observed in any of the analyzed variables. The results show for the first time in Nellore cattle the relationship between the size of ovarian structures and blood flow (quantity and intensity) as well as the ability of the CL to produce progesterone. The intensity of the POF pixels proved to be relevant, demonstrating correlations with the size and flow of the CL, which were not found when evaluating only the number of pixels, thus revealing the importance of evaluating complementary characteristics of the flow.

Abstract Background The influence of different crystalloid solutions infused during deceased-donor kidney transplant on the incidence of delayed graft function remains unclear. We investigated the influence of Plasma-Lyte® vs. 0.9% saline on the incidence of delayed graft function in deceased-donor kidney transplant recipients. Methods We conducted a single-blind randomized controlled trial of 104 patients aged 18 to 65 years who underwent deceased-donor kidney transplant under general anesthesia. Patients were randomly assigned to receive either Plasma-Lyte® (n = 52) or 0.9% saline (n = 52), at the same infusion volume, for intraoperative fluid replacement. The primary outcome was the occurrence of delayed graft function. Secondary outcomes included metabolic and electrolytic changes at the end of surgery. Results Two patients in the Plasma-Lyte® group and one in the 0.9% saline group died postoperatively and were not included for analysis. The incidence of delayed graft function in Plasma-Lyte® and 0.9% saline groups were 60.0% (95% Confidence Interval [95% CI 46.2-72.4]) and 74.5% (95% CI 61.1-84.4), respectively (p= 0.140). Mean (standard deviation) values of immediate postoperative pH and serum chloride levels in Plasma-Lyte® and 0.9% saline groups were 7.306 (0.071) and 7.273 (0.061) (p= 0.013), and 99.6 (4.2) mEq.L-1 and 103.3 (5.6) mEq.L-1, respectively (p< 0.001). All other postoperative metabolic and electrolyte variables were not statistically different at the immediate postoperative period (p> 0.05). Conclusion In deceased-donor kidney transplant recipients, the incidence of delayed graft function is not influenced by Plasma-Lyte® or 0.9% saline used for intraoperative fluid replacement.

Abstract: En | Text: En | PDF: En

ABSTRACT Introduction: Congenitally corrected transposition of the great arteries (CCTGA) is a rare anomaly. Current data available regarding adult cases is derived from small series, information simultaneously presented in pediatric publications, and one classical multicenter study. This review, not aimed to exhaust the subject, has the purpose to examine the literature addressing presentation, diagnostic methodology, and management of afflicted adult patients. Methods: A comprehensive search was undertaken in three major databases (PubMed, Cochrane, SciELO), using the keywords “congenitally corrected transposition of the great arteries” and “adults”. Relevant articles in English, Spanish, and Portuguese were extracted and critically appraised in this review. Steps for study selection were: (1) identification of titles of records through databases searching, (2) removal of duplicates, (3) screening and selection of abstracts, (4) final inclusion in the study. Results: Four hundred sixty-five publications on CCTGA in adult patients were retrieved, and 166 were excluded; 299 studies were used for this review including 76 full-text articles, 70 studies related to general aspects of the subject, and, due to the small number of publications, 153 case reports. Sixty-one articles referring to combined experiences in pediatric and adult patients and judged to be relevant, but retrieved from another sources, were also included. Conclusion: Albeit clinical presentation and diagnostic criteria have been well stablished, there seems to be room for discussion related to clinical and surgical management of CCTGA in adults. Considering the rarity of the disease, well designed multicenter studies may provide answers.

RESUMO Objetivo: Descrever uma técnica cirúrgica inovadora para transplante de olho em um modelo animal em coelhos. Métodos: Seis coelhos machos com Dutch Belted foram submetidos à orbitotomia lateral do olho direito, com ampla exposição da anatomia retrobulbar, dissecção do cone muscular, exposição e secção distal do nervo óptico seguida de anastomose por vicryl (Grupo 1) ou cola de fibrina (Grupo 2). O registro da eletrorretinografia foi realizado antes da secção do nervo óptico e a cada 30 segundos após, para monitorar a função da retina. O olho esquerdo foi usado como grupo controle. Resultados: Após a ressecção do nervo óptico, a estabilidade da amplitude da eletrorretinografia foi perdida no olho direito após 302 segundos no Grupo 1 e após 296 segundos no Grupo 2. O olho esquerdo manteve eletrorretinografia estável por períodos mais longos. Conclusão: O modelo animal de transplante total de olho foi eficaz em descrever uma nova técnica cirúrgica para ser utilizada em laboratório com coelhos, com sucesso do procedimento anatômico. Novos estudos esclarecerão os melhores métodos de anastomose e manutenção da função do órgão receptor.

ABSTRACT Purpose: To describe an innovative animal model of eye transplantation used in rabbits. Methods: six Dutch-belted male rabbits were submitted to lateral orbitotomy in the right eye, wide retrobulbar anatomy exposure, dissection of the structures, identification and distal section of the optic nerve followed by anastomosis either by vicryl (group 1) or fibrin glue (group 2). Electroretinography recording was performed before the section of the optic nerve and every 30 seconds after, to monitor the function of retina. Left eye was used as control group. Results: After optic nerve resection and anastomosis, stable ERG amplitude of the right eye was lost after 302 seconds in group 1 and after 296 seconds on group 2. Left eye kept longer stable ERG amplitude curves. Conclusions: The animal model of whole eye transplantation was effective in describing a novel technique to be used in rabbits, with success of the anatomic procedure. Further studies will clarify the best anastomosis methods and maintenance of function of the receptor organ. Translational relevance: this animal model of whole eye transplantation provides a novel perspective for blind patients and the research models, since we describe a novel mammal animal model. This model can be used as basis of a human model of whole eye transplantation in future studies.

RESUMO Introdução: o tratamento do câncer de adrenal benigno (hormonalmente ativo ou não funcional) e maligno inclui a adrenalectomia. A experiência dos cirurgiões e a cirurgia realizada por cirurgiões de alto volume foram associadas a menos complicações e menor custo. O objetivo do estudo foi descrever e comparar o número de cirurgias, a taxa de mortalidade e o tempo de internação para adrenalectomias realizadas entre 2008 e 2019 na rede pública de saúde de São Paulo. Métodos: trata-se de um estudo ecológico. Os dados foram coletados da Plataforma TabNet do Departamento de Informática do Sistema Único de Saúde. Os hospitais foram divididos em três subgrupos de acordo com o volume cirúrgico e hospitais com e sem programa de residência médica em Urologia. Os resultados foram comparados entre os grupos. Resultados: no período estudado, 943 adrenalectomias foram realizadas em São Paulo. As taxas de mortalidade durante a internação de acordo com o volume cirúrgico hospitalar foram: não foram relatados óbitos em hospitais de baixo volume; 0,015% em hospitais de volume intermediário e 0,004% em alto volume. O tempo médio de permanência na UTI foi de 1,03 dias nos hospitais de baixo volume; 2,8 nos de médio volume e 1,12 nos de alto volume (análise entre centros de médio e alto volume com significância estatística, p=0,016). Conclusão: as taxas de mortalidade foram muito baixas em todos os grupos. A permanência na UTI foi menor em centros de alto volume do que em centros de volume intermediário.

ABSTRACT Introduction: treating benign (hormonally active or nonfunctional) and malignant adrenal cancer includes adrenalectomy. The expertise of surgeons and surgery performed by high-volume surgeons were associated with fewer complications and lower cost. We aimed to describe and compare the number of surgeries, mortality rate, and length of hospital stay for adrenalectomies performed between 2008 and 2019 in the public health system of São Paulo. Methods: this was an ecological study. The data were collected using the TabNet Platform of the Unified Health System Department of Informatics. Outcomes analyzed included the number of surgeries performed, mortality rate during hospital stay, and length of hospital stay. Public hospitals in Sao Paulo were divided into three subgroups according to the surgical volume of adrenalectomies performed as well as hospitals with and without a residency program in Urology, and the results were compared among them. Results: a total of 943 adrenalectomies were performed in Sao Paulo between 2008 and 2019. Mortality rates during hospital stay according to hospital surgical volume were no reported deaths in low-volume, 0.015% in intermediate-volume, and 0.004% in high-volume hospitals. The average length of the ICU stay was 1.03 days in low-volume, 2.8 in intermediate-volume, and 1.12 in high-volume hospitals (analysis between intermediate and high volume centers with statistical significance, p=0.016). Conclusions: despite no statistically significant differences among the groups analyzed, mortality rates were very low in all groups. ICU stay was shorter in high-volume centers than in intermediate-volume centers.

RESUMO Objetivos: investigar o impacto da idade, da disfunção motora e dos sintomas neuropsiquiátricos sobre a qualidade de vida de pessoas com esclerose múltipla na comparação com controles saudáveis. Métodos: 141 participantes foram testados em uma única sessão. As avaliações foram compostas por questionários gerais aplicados em ambos os grupos e por instrumentos específicos à esclerose múltipla. Modelos de regressão múltipla foram usados para avaliar relações entre preditores e desfecho. Resultados: idade, disfunção motora e sintomas neuropsiquiátricos explicaram 56,6% da qualidade de vida do grupo esclerose múltipla. Idade e sintomas neuropsiquiátricos corresponderam a 36,6% da qualidade de vida do grupo-controle. Idade impactou mais o grupo esclerose múltipla do que o grupo-controle. Sintomas neuropsiquiátricos afetaram os grupos semelhantemente. A disfunção motora impactou 21,9% da qualidade de vida na esclerose múltipla. Conclusões: os preditores explicaram considerável variação da qualidade de vida na esclerose múltipla, o que deve nortear políticas públicas de saúde.

ABSTRACT Objectives: to investigate the impact of age, motor dysfunction and neuropsychiatric symptoms on the quality of life of people with multiple sclerosis in comparison to healthy peers. Methods: a total of 141 participants were tested in a single session. The assessments were composed by general questionnaires applied in both groups and by specific instruments restricted to multiple sclerosis. Multiple regression models were applied to assess relationships between predictors and outcome. Results: age, motor dysfunction and neuropsychiatric symptoms explained 56.6% of quality of life of the multiple sclerosis group. Age and neuropsychiatric symptoms explained 36.6% of quality of life in the control group. Age impacted more the multiple sclerosis group than the control group. Neuropsychiatric symptoms affected both groups similarly. Motor dysfunction impacted 21.9% of the quality of life in multiple sclerosis. Conclusions: the predictors explained considerable variance of quality of life in multiple sclerosis, which should guide public health policies.
