RESUMO

Objetivo: A tecnologia assistiva (TA) busca suprir ou reduzir o impacto das deficiências na execução de tarefas da vida cotidiana. Embora muitas pessoas necessitem de TA, em 2021, a OMS estimou que apenas uma em cada dez pessoas tinha acesso a ela. Com a oferta retraída e a demanda em alta, observou-se um movimento mundial crescente de inovações em TA e a abertura de um cenário de oportunidades para esse mercado. O objetivo deste artigo é avaliar o mercado de TA no Brasil e as projeções futuras, no cenário mundial. Métodos: A pesquisa foi realizada em três etapas. Primeiramente, foi realizado um estudo bibliográfico do Livro Branco da Tecnologia Assistiva no Brasil (2017), para reconhecimento dos desafios do mercado brasileiro. Em seguida, foi realizado um estudo sobre o cenário de crédito nacional, com foco em financiamento de TA. Para compreensão do mercado mundial, foi realizada uma pesquisa nos sites de análise de mercado de TA. Resultados: Há escassez de TA no Brasil. Os principais fornecedores são pequenas e médias empresas, e são escassos os incentivos fiscais e de crédito, assim como os investimentos em pesquisa, desenvolvimento e inovação. Em escala mundial, o mercado de TA foi avaliado em US$ 21,95 bilhões de dólares em 2022, devendo atingir o valor de US$ 31,22 bilhões de dólares até o ano de 2030. Conclusão: O mercado mundial de TA está em franca expansão e apresenta grande potencial de abertura para novos mercados. Esse cenário reflete um momento de oportunidades de negócio para as empresas nacionais.


Objective: Assistive Technology (AT) seeks to overcome or reduce the impact of deficiencies when performing everyday tasks. Although many people needed AT, in 2021, the WHO estimated that only one in ten people had access. With reduced supply and rising demand, a growing global movement of AT innovations was inspired, opening up a scenario of opportunities for this market. The objective of this study is to evaluate the AT market in Brazil and future projections on the global stage. Methods: The research was carried out in three stages. Firstly, a bibliographical study of the "White Book of Assistive Technology in Brazil" was carried out to recognize the challenges of the Brazilian market. Next, a study was carried out on the national credit scenario, focusing on TA financing. To understand the global market, research was carried out on TA market analysis websites. Results: There is a shortage of AT in Brazil. The main suppliers are small and medium-sized companies, and tax and credit incentives, as well as investments in Research, Development and Innovation, are scarce. On a global scale, the AT market was valued at US$ 21.95 billion in 2022, and is expected to reach a value of US$ 31.22 billion by the year 2030. Conclusion: The global AT market is in rapid expansion and presents great potential for opening up new markets. This scenario reflects a moment of business opportunities for national companies.

RESUMO

Background: Real-world data on the effectiveness and safety of ustekinumab (UST) in ulcerative colitis (UC) are lacking in Latin America. In this study, we aimed to describe the effectiveness and safety of UST in a real-world multicenter cohort of Brazilian patients with UC. Methods: We conducted a multicenter retrospective observational cohort study, including patients with moderate-to-severe UC (total Mayo score 6-12, with an endoscopic subscore of 2 or 3) who received UST. The co-primary endpoints were clinical remission, defined as a total Mayo score ≤2 at 1 year, with a combined rectal bleeding and stool frequency subscore of ≤1, and endoscopic remission (endoscopic Mayo subscore of 0) within 1 year from baseline. Secondary endpoints included clinical response between weeks 12 and 16, endoscopic response within 1 year of starting UST, steroid-free clinical remission at week 52, and biochemical remission at week 52. We also evaluated UST treatment persistence and safety. Results: A total of 50 patients were included (female, n = 36, 72.0%), with a median disease duration of 9.2 years (1-27). Most patients had extensive colitis (n = 38, 76.0%), and 43 (86.0%) were steroid dependent at baseline. Forty patients (80.0%) were previously exposed to biologics (anti-TNF drugs, n = 31; vedolizumab [VDZ], n = 27). The co-primary endpoints of clinical remission at 1 year and endoscopic remission within 1 year were achieved by 50.0% and 36.0% of patients, respectively. Clinical response at weeks 12-16 was 56.0%, and endoscopic response, steroid-free clinical remission, and biochemical remission at week 52 were 68.0%, 46.5%, and 50.0%, respectively. The UST treatment persistence rate at 24 months was 73.7%. During the follow-up, 10 patients (20.0%) were hospitalized, mostly due to disease progression, and 3 patients required colectomy. Nine patients (18.0%) discontinued the drug mainly due to a lack of effectiveness. Twenty-seven adverse events (AEs) were reported, 16 of which were considered as serious AEs. Conclusions: In this real-world cohort of difficult-to-treat UC patients, UST was associated with improvements in clinical, biochemical, and endoscopic outcomes. The safety profile was favorable, consistent with the known profile of UST.

RESUMO

This study aimed to investigate recovery markers among elite climbers following the National Boulder Championship. We assessed maximum isometric hand grip strength (HS), forearm swelling (circumference), delayed soreness in forearm muscles, tiredness, and exercise readiness at several time points: pre-competition, immediately post-competition (within 4 min after their last effort), and 12, 24, 48, and 60 h post-competition. Maximum isometric hand grip strength decreased by 6.38 ± 1.32% (p = 0.006) post-12 h, returning to pre-competition values post-24 h (all p > 0.05). Forearm circumference (FC) increased 1.78 ± 1.77% (p < 0.001) post-competition, returning to pre-competition values post-12 h (all p > 0.05). Forearm pain (FP) increased post-competition (p = 0.002) and post-12 h (p < 0.001), returning to pre-competition values post-24 h (all p > 0.05). Tiredness increased post-competition (p < 0.001), post-12 h (p < 0.001), and post-24 h (p < 0.001), returning to pre-competition values post-48 h (all p > 0.05). Climbing readiness was reduced post-competition (p < 0.001), post-12 h (p < 0.001), post-24 h (p < 0.001), and post-48 h (p = 0.005), only returning to pre-competition values post-60 h (p = 0.189). Visual analysis of individual data pointed out a relatively small variability in the HS and FC markers, while FP, tiredness, and readiness exhibited larger individual variations. These findings indicate that different recovery patterns exist for the analyzed markers, suggesting that athletes may require up to 60 h after a competition to fully recover and regain their ability to face new competitive challenges.

RESUMO

BACKGROUND: Inflammatory bowel diseases are immune-mediated disorders that include Crohn's disease (CD) and ulcerative colitis (UC). UC is a progressive disease that affects the colorectal mucosa causing debilitating symptoms leading to high morbidity and work disability. As a consequence of chronic colonic inflammation, UC is also associated with an increased risk of colorectal cancer. OBJECTIVE: This consensus aims to provide guidance on the most effective medical management of adult patients with UC. METHODS: A consensus statement was developed by stakeholders representing Brazilian gastroenterologists and colorectal surgeons (Brazilian Organization for Crohn's Disease and Colitis [GEDIIB]). A systematic review including the most recent evidence was conducted to support the recommendations and statements. All recommendations/statements were endorsed using a modified Delphi Panel by the stakeholders/experts in inflammatory bowel disease with at least 80% or greater consensus. RESULTS AND CONCLUSION: The medical recommendations (pharmacological and non-pharmacological) were mapped according to the stage of treatment and severity of the disease onto three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/patient monitoring after initial treatment. The consensus targeted general practitioners, gastroenterologists and surgeons who manage patients with UC, and supports decision-making processes by health insurance companies, regulatory agencies, health institutional leaders, and administrators.

RESUMO

BACKGROUND: Inflammatory bowel disease (IBD) is an immune-mediated disorder that includes Crohn's disease (CD) and ulcerative colitis. CD is characterized by a transmural intestinal involvement from the mouth to the anus with recurrent and remitting symptoms that can lead to progressive bowel damage and disability over time. OBJECTIVE: To guide the safest and effective medical treatments of adults with CD. METHODS: This consensus was developed by stakeholders representing Brazilian gastroenterologists and colorectal surgeons (Brazilian Organization for Crohn's disease and Colitis (GEDIIB)). A systematic review of the most recent evidence was conducted to support the recommendations/statements. All included recommendations and statements were endorsed in a modified Delphi panel by the stakeholders and experts in IBD with an agreement of at least 80% or greater consensus rate. RESULTS AND CONCLUSION: The medical recommendations (pharmacological and non-pharmacological interventions) were mapped according to the stage of treatment and severity of the disease in three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/patient monitoring after initial treatment. The consensus is targeted towards general practitioners, gastroenterologists, and surgeons interested in treating and managing adults with CD and supports the decision-making of health insurance companies, regulatory agencies, and health institutional leaders or administrators.

RESUMO

This prospective, observational, open-label study aimed to provide access to ustekinumab prior to market authorization and assess its safety and effectiveness in patients with Crohn's disease (CD) refractory to anti-tumor necrosis factor-α and conventional drugs in Brazil. Patients with a diagnosis of moderate-to-severe active CD for ≥3 months before screening received ustekinumab in a single intravenous induction dose (~6 mg/kg) at week 0, and a 90 mg maintenance dose, subcutaneously, every 8 or 12 weeks, from week 8 through to 80. Serious adverse events (SAE), adverse drug reactions (ADR), clinical response (per CD Activity Index and Harvey Bradshaw Index (HBI) scores), remission (per HBI scores), biomarkers (C-reactive protein (CRP) and fecal calprotectin (FC)) and endoscopic improvement rate over 80 weeks were assessed. Patients with a mean age of 39.9 years were assessed. Discontinuation rate was low (23%) and most adverse events were mild (68.7%). The SAE rate was 21% (mostly infections/infestations or gastrointestinal disorder), and ADR rate was 44%. The CD Activity Index and HBI scores decreased (by 74% and 81%, respectively) with 50% of patients showing normalized CRP and FC, and 63% achieved endoscopic improvement. Ustekinumab was fairly safe, well tolerated and effective in a Brazilian cohort of CD patients.

RESUMO

The aim of this study was to evaluate the time course of the effects of far-infrared emitting fabric (FIR) on neuromuscular performance of knee extensor over 120 h and to investigate whether the use of FIR affects semen. This is a crossover, randomized, double-blind, and placebo-controlled trial split into neuromuscular and fertility assessments. Four (28.8 ± 4.7 years old) and six (29 ± 3.9 years old) healthy, resistance-trained males completed all neuromuscular and fertility assessments, respectively. In neuromuscular assessments, for five consecutive days, the participants underwent neuromuscular tests in an isokinetic dynamometer (maximal isometric voluntary contraction (MVC) and fatigue test) every 24 h in both conditions (FIR and Placebo). In fertility assessments, participants performed three semen collections: Baseline, FIR, and Placebo. FIR and Placebo collections were performed after five consecutive days of use of the pants. Conventional parameters and sperm DNA fragmentation were evaluated. In the FIR condition, the participants showed significant differences in total work at 96 h (p < 0.001; Cohen's d = 3.73), 120 h (p = 0.01; Cohen's d = 2.65), and pre-MVC at 120 h (p = 0.02; Cohen's d = 2.15) when compared to Placebo. FIR did not significantly (p > 0.05) affect the conventional semen parameters or sperm DNA fragmentation compared to Baseline or Placebo. FIR improved the knee extensor neuromuscular performance of healthy resistance-trained individuals, with 112.4 ± 7.8 h accumulated, and did not affect their seminal parameters (conventional or sperm DNA fragmentation), with 113.1 ± 10.2 h accumulated.

RESUMO

BACKGROUND: Anti-TNF therapy represented a landmark in medical treatment of ulcerative colitis (UC). There is lack of data on the efficacy and safety of these agents in Brazilian patients. The present study aimed to analyze rates of clinical and endoscopic remission comparatively, between adalimumab (ADA) and infliximab (IFX), in Brazilian patients with UC, and evaluate factors associated with clinical and endoscopic remission after 1 year of treatment. METHODS: A national retrospective multicenter study (24 centers) was performed including patients with UC treated with anti-TNF therapy. Outcomes as clinical response and remission, endoscopic remission and secondary loss of response were measured in different time points of the follow-up. Baseline predictive factors of clinical and endoscopic remission at week 52 were evaluated using logistic regression model. Indirect comparisons among groups (ADA and IFX) were performed using Student's t, Pearson χ2 or Fisher's exact test when appropriated, and Kaplan Meier analysis. RESULTS: Overall, 393 patients were included (ADA, n = 111; IFX, n = 282). The mean age was 41.86 ± 13.60 years, 61.58% were female, most patients had extensive colitis (62.40%) and 19.39% had previous exposure to a biological agent. Overall, clinical remission rate was 66.78%, 71.62% and 82.82% at weeks 8, 26 and 52, respectively. Remission rates were higher in the IFX group at weeks 26 (75.12% vs. 62.65%, p < 0.0001) and 52 (65.24% vs. 51.35%, p < 0.0001) when compared to ADA. According to Kaplan-Meier survival curve loss of response was less frequent in the Infliximab compared to Adalimumab group (p = 0.001). Overall, endoscopic remission was observed in 50% of patients at week 26 and in 65.98% at week 52, with no difference between the groups (p = 0.114). Colectomy was performed in 23 patients (5.99%). Age, non-prior exposure to biological therapy, use of IFX and endoscopic remission at week 26 were associated with clinical remission after 52 weeks. Variables associated with endoscopic remission were non-prior exposure to biological therapy, and clinical and endoscopic remission at week 26. CONCLUSIONS: IFX was associated with higher rates of clinical remission after 1 year in comparison to ADA. Non-prior exposure to biological therapy and early response to anti-TNF treatment were associated with higher rates of clinical and endoscopic remission.

RESUMO

The aim of this study was to verify if exposure to the far-IR emitted by fabric (FIR) is able to improve the neuromuscular performance of the knee extensors of resistance-trained males regardless of changes of the temperature. It is a crossover, randomized, double-blind, and placebo-controlled trial. Fourteen resistance-trained males (age: 24.3 ± 4 years; body mass: 82.8 ± 11.3 kg; height: 176.3 ± 4.2 cm) were randomly assigned to one of initial conditions: FIR (n = 7) or placebo (n = 7). After 4 days, the participants were submitted to neuromuscular tests in an isokinetic dynamometer (maximal isometric voluntary contraction (MVC) and fatigue test). After a week of washout, participants performed the other condition. We measured peak torque (Nm), total work (J), fatigue index (%), root mean square (mV), median frequency (Hz), and temperature (°C) of thigh. The FIR was worn for 82 ± 19 h before the experimental session, totaling 317 ± 74 kJ of energy irradiation. There was a significant increase (p < 0.05) for pre-MVC (318.5 ± 68.7 Nm) and post-MVC (284.1 ± 58.2 Nm), and a trend (p = 0.055) for significant increase for total work (4,122.2 ± 699.8 J) on FIR condition regardless of none change on temperature and electromyographic (EMG) signals. FIR improved the neuromuscular performance of knee extensors in resistance-trained males regardless of changes on temperature and EMG. The present results suggest that the FIR could optimize the neuromuscular performance with 82 ± 19 h of wear.

RESUMO Contexto: As doenças inflamatórias intestinais são doenças imunomediadas que incluem a doença de Crohn (DC) e a retocolite ulcerativa (RCU). A RCU é uma doença progressiva que acomete a mucosa colorretal causando sintomas debilitantes levando a alta morbidade e incapacidade laboral. Como consequência da inflamação crônica do cólon, a RCU também está associada a um risco aumentado de câncer colorretal. Objetivo: Este consenso visa fornecer orientações sobre o manejo médico mais eficaz de pacientes adultos com RCU. Métodos: As recomendações do consenso foram desenvolvidas por gastroenterologistas e cirurgiões colorretais referências no Brasil (membros da Organização Brasileira para Doença de Crohn e Colite [GEDIIB]). Uma revisão sistemática, incluindo as evidências mais recentes, foi conduzida para apoiar as recomendações. Todas as recomendações foram endossadas pelas partes interessadas/especialistas em doença inflamatória intestinal usando um Painel Delphi modificado. O nível de concordância para alcançar consenso foi de 80% ou mais. Resultados e conclus ão: As recomendações médicas (farmacológicas e não farmacológicas) foram mapeadas de acordo com o estágio de tratamento e gravidade da doença em três domínios: manejo e tratamento (intervenções medicamentosas e cirúrgicas), critérios para avaliar a eficácia do tratamento médico, e acompanhamento/monitoramento do paciente após o tratamento inicial. O consenso foi direcionado a clínicos gerais, gastroenterologistas e cirurgiões que tratam pacientes com RCU e apoia os processos de tomada de decisão por companhias de seguro de saúde, agências reguladoras, líderes institucionais de saúde e administradores.

RESUMO

Introdução:Aadolescência é um período curto, porém é nela que ocorrem mudanças biológicas, físicas e psicológicas determinantes na busca da autoafirmação e que podem acarretar complicações no ciclo de vida. A gravidez vista nesta etapa é uma realidade no Brasil e, apesar de susceptível em qualquer classe social,os fatores econômico e social são determinantesnos índices estatísticos. Objetivo:Analisar o perfil das adolescentes que utilizam os serviços do ambulatório e enfermaria de obstetrícia do Hospital Veredas, identificar os fatores que levaram a uma maternidade precoce, as relações sociais, familiares e escolares das adolescentes, além das suas expectativas futuras na construção afetiva da relação mãe-filho e dos possíveis riscos gerados à saúde de ambos. Metodologia:Pesquisa analítica, individual, transversal e observacional, com dados coletados através de análise de prontuários para seleção da amostra e entrevistas com as gestantes do ambulatório e enfermaria de obstetrícia do Hospital Veredas, Maceió-Alagoas, entre janeirode 2020enovembro de 2020. Resultadose Discussão:Das adolescentes analisadas, 52,3% eram menores de idade, dadosignificativo que demonstraa natureza social destas gestações. Quando questionadas sobre sua percepção quanto a gestação, 57,5% declararamque se tratava de uma gravidez indesejada,informação que associadaa narrativa dessas mulheres, demonstra que a gravidez associada a ausência de uma rede de apoio, agrava sua rejeição, refletindo em um isolamento e dificuldade de aceitação. Pode-se constatar através de análise inferencial que uma tendência dasadolescentes etilistas evoluírem com gestações pré-termo (tempo de gestação < 37 semanas) e recém-nascidos prematuros. Conclusões:Através da análise dos dados e da bibliografia analisada, nota-se que a gravidez na adolescência é uma realidade no município de Maceió, e permanece um importante problema de saúde pública gerando impactos negativos nos aspectos sociais, econômicos e nos indicadores de saúde dessas jovens (AU).


Introduction:Adolescence is a short period, but it is when biological, physical and psycological changes happen and those are decisive in the search for self-affirmation and can cause complications in the life cycle. Teenage pregnancy is a reality in Brazil and, although susceptible in any social class, the economic and social factors are determinant in the statistical indexes. Objective:To analyze the profile of adolescents who use the services of the ambulatory and obstetric ward of Hospital Veredas, identifying thefactors that led to an early motherhood, the social, family and school relationships of the adolescents, in addition to their future expectations in the affective construction the mother-child relationship and the possible risks to their health. Methodology:Analytical, individual, cross-sectional and observational research, with data collected through analysis of medical records for sample selection and interviews with pregnant women from the outpatient clinic and obstetrics ward of Hospital Veredas, Maceió-Alagoas, between January2020toNovember 2020. Resultsand Discussion:Of the adolescents analyzed, 52.3% were minors, a significant figure that reflects the social nature of these pregnancies. When asked about their perception of pregnancy, 57.5% stated that it was an unwanted pregnancy, given that associated with the narrative of these women, demonstrates that pregnancy associated with the absence of a support network, aggravates their rejection, reflecting on a isolation and difficulty of acceptance. It can be seen through inferential analysis that a tendency for alcooholic teenagers to evolve with preterm pregnancies (gestation time <37 weeks) and premature newborns. Conclusions:Through the analysis of the data and the analyzed bibliography, it is noted that teenage pregnancy is a reality in the city of Maceió andremains an important public health,problem generating negative impacts on the social, economic and health indicators of these young women (AU).

RESUMO

The present study aimed to investigate the influence of months of birth on anthropometry, body composition, biological maturation, and motor performance in young Brazilian soccer players. Young Brazilian soccer players from the Under-13 (n = 50; 13.6 ± 0.3 years), Under-15 (n = 50; 15.5 ± 0.4 years), and Under-17 categories (n = 46; 17.7 ± 0.3 years) took part in this study. Athletes were divided according to chronological age, 1st tertile (January to April); 2nd tertile (May to August); and 3rd tertile (September to December). Anthropometry, body composition, biological maturation, and motor performance variables were evaluated for all participants. There were no differences between the U-13, U-15, and U-17 categories regarding birth tertiles (p > 0.05). Differences between the ages and birth tertiles were observed for the stature, body mass, and lean body mass (p < 0.05). Moreover, differences were found in maturational status between the ages and birth tertiles (p < 0.05). In general, U-13 players showed lower values compared to U-15 and U-17 players in tests of motor performance. In addition, there was a difference in motor performance between the birth tertiles only for RSA variables. The months of birth influenced the stature, body mass, lean body mass, and repeated sprint ability in the U-13 and U-15 categories. Thus, care should be taken during the process of talent selection, as many young players could be underestimated due to their date of birth.

RESUMO

Objetivo: O objetivo deste trabalho foi identificar, por meio da interposição de questionário, pontos favoráveis e pontos potencialmente impeditivos à compra da Smart Mobb® como tecnologia assistiva auxiliar à mobilidade de pessoas com deficiência visual. Métodos: A aplicação do questionário foi realizada na Fundação Dorina Nowill para Cegos, instituição especializada no atendimento e reabilitação de pessoas com deficiência visual. A entrevista consistiu em perguntas sobre o perfil socioeconômico, social, tecnológico, sob o contexto das tecnologias assistivas, e de saúde, relativas ao indivíduo e às dificuldades que ele enfrenta no dia a dia por causa do seu quadro de deficiência visual. Resultados: Foram entrevistados oito candidatos. Os resultados indicaram que a Smart Mobb® possui características que apresentam identidade com as preferências relatadas pelas pessoas que participaram do estudo, apresentando inconsistência apenas quanto ao valor médio mensal estimado para venda e ao que esses indivíduos estão dispostos a pagar. Conclusão: Verificou-se que existe o desejo, por parte dos potenciais demandantes, quanto a soluções em tecnologias assistivas que carreguem maior teor tecnológico e que surjam como proposta de solução para o problema da mobilidade urbana. Com relação ao preço, a maioria dos entrevistados está disposta a pagar um percentual médio mensal abaixo do mínimo estipulado para a aquisição da bengala eletrônica Smart Mobb® , o que configura um potencial fator impeditivo à adesão


Objective: The objective of this work was to identify, through the questionnaire, favorable points and potentially impeding points for the purchase of Smart Mobb® as an auxiliary mobility technology for people with visual impairments. Methods: The questionnaire was applied at the Dorina Nowill Foundation for the Blind, an institution specialized in the care and rehabilitation of visually impaired people. The interview consisted of questions about the socioeconomic profile; Social; technological, in the context of assistive technologies; and health, including the individual and the difficulties he faces on a daily basis using his visual impairment. Results: Eight candidates were interviewed. The results indicate that Smart Mobb® has features that display the identity with respect to the people who study, showing inconsistency only in terms of the estimated average monthly value for sale and that these items are available for payment. Conclusion: It was found that it exists or desires, on the part of users who demand as much solutions in assisted technologies that carry greater technological content, and that appear as a solution proposal for the problem of urban mobility. With regard to price, most respondents are willing to pay an average monthly percentage below the minimum stipulated for the purchase of the Smart Mobb® electronic cane, or to set up a potential impediment to adherence

RESUMO

The objective of the study was to investigate the effects of using lifting straps on the lat pull-down exercise on maximal strength, number of repetitions, and muscle activation. Twelve resistance-trained men participated (age 27 ± 4 years, body mass 84 ± 10 kg, height 177 ± 6 cm, resistance training experience 6.6 ± 2.4 years). All participants performed the 1RM tests and training protocols either with the lifting straps (WS) or without (WOS). Exercise sessions for both conditions (WS and WOS) consisted of 3 sets to concentric failure with a load of 70% of one repetition maximum (1RM) and rest intervals of 60 s. For the 1RM test, no difference was observed between WS and WOS conditions (96.5 ± 12.7 kg and 96.6 ± 11.9 kg, respectively). There were no differences between the WS and WOS conditions in the number of repetitions per set, total repetitions and latissimus dorsi muscle activation. In conclusion, the findings of this study demonstrate that the use of lifting straps in the lat pull-down exercise by resistance-trained individuals does not promote beneficial effect in the 1RM value, the number of repetitions performed with 70% of 1RM, and muscle activation.

RESUMO

BACKGROUND: The IBD National Patient Registry is an initiative of the GEDIIB (Brazilian Study Group of Inflammatory Bowel Disease) who aims to survey the epidemiological profile of IBD patients through the creation of a centralized registry with data on patients monitored in public and private health services which will allow the planning of actions by the GEDIIB to facilitate the diagnosis and access to treatment of IBD, enabling the implementation of actions of the GEDIIB and the partnership with government agencies to improve care and, consequently, the quality of life of patients with IBD. This study aims to show the results of the IBD National Patient Registry. METHODS: A cohort study was performed. Data were collected from July 2020 to August 2021. Data were obtained from medical records and/or from patients during the regular follow-up visit and stored in pre-established records for further analysis. Only patients with an established diagnosis of CD and UC were included. The study was approved by the local ethical committees and all patients signed the consent form. RESULTS: In total, 797 patients were included, 60% with UC and 40% with CD; 52.9% from University Hospitals. The mean age was 44.75 ± 16.11 (12 - 92y), 59.9% female, 59.3% married, 76.4% Caucasian, 85.1% non-smokers, 30.5% completed higher education, 14.9% presented familial history of IBD. The age of onset of symptoms ranged from 3 - 79 years (32.94 ± 14.22) and 33.2% presented diarrhea as an initial manifestation. The age of diagnosis ranged from 4 - 81 years (35.07 ± 14.60) and the time from symptoms to diagnosis ranged from 1 to 2 years. The Montreal classification of CD patients were A1: 6.3%, A2: 59.9%, A3: 33.8%; L1: 38%, L2: 16.7%, L3: 43.9%, B1: 51.5%, B2: 27.8%, B3: 7.8%; perianal 12.8%. In UC, 47.8% presented pancolitis, 30.3% left-sided and 21.8% distal colitis. EIMs were present in 45.7% of patients, the most frequent being rheumatological 21.8%. Comorbidities were present in 72%, the most frequent were high blood pressure (15.3%) and diabetes (6.3%); 50% were with BMI > 25 Kg/m2. Most of the patients were in use of medical therapy (95.5%), of which 81.3% salicylate, 70.3% biological therapy, 49% immunosuppressor, 25.6% corticosteroid and 1.2% tofacitinib. Regarding biological therapy, the following medications were used: infliximab 47.6%, adalimumab 28.4%, vedolizumab 9.5%, ustekinumab 7.5%, certolizumab 2.2% and golimumab 1.3%. Eleven women used the medication during pregnancy. IBD surgery-related was performed in 69.7%, 77.2% abdominal and 22.8% perianal. Almost 30% performed more than one surgery. In 62% of patients, at least one complication was reported; most of them were infective disorders, demanding prolonged hospitalizations. CONCLUSION: To date, there is no IBD epidemiologic study covering the entire Brazilian territory. The results found with the registry will be fundamental to show the epidemiology of a country with continental dimensions such as Brazil. The greater the number of researchers included and from different regions of the country, the greater the representativeness of the data and may even help direct government actions on behalf of IBD patients.

RESUMO

BACKGROUND: Inflammatory bowel diseases (IBD) are chronic inflammatory affections of recurrent nature whose incidence and prevalence rates have increased, including in Brazil. In long term, they are responsible for structural damage that impacts quality of life, morbidity and mortality of patients. OBJECTIVE: To describe the profile of physicians who treat IBD patients as well as the characteristics of IBD care, unmet demands and difficulties. METHODS: A questionnaire containing 17 items was prepared and sent to 286 physicians from 101 Brazilian cities across 21 states and the Federal District, selected from the register of the State Commission of the "Study Group of Inflammatory Bowel Disease of Brazil" (GEDIIB). RESULTS: The majority of the physicians who answered the questionnaire were gastroenterologists and colorectal surgeons. More than 60% had up to 20 years of experience in the specialty and 53.14% worked at three or more locations. Difficulties in accessing or releasing medicines were evident in this questionnaire, as was referrals to allied healthy professionals working in IBD-related fields. More than 75% of physicians reported difficulties in performing double-balloon enteroscopy and capsule endoscopy, and 67.8% reported difficulties in measuring calprotectin. With regard to the number of patients seen by each physician, it was shown that patients do not concentrate under the responsibility of few doctors. Infliximab and adalimumab were the most commonly used biological medicines and there was a higher prescription of 5-ASA derivatives for ulcerative colitis than for Crohn's disease. Steroids were prescribed to a smaller proportion of patients in both diseases. The topics "biological therapy failure" and "new drugs" were reported as those with higher priority for discussion in medical congresses. In relation to possible differences among the country's regions, physicians from the North region reported greater difficulty in accessing complementary exams while those from the Northeast region indicated greater difficulty in accessing or releasing medicines. CONCLUSION: The data obtained through this study demonstrate the profile of specialized medical care in IBD and are a useful tool for the implementation of government policies and for the Brazilian society as a whole.

RESUMO CONTEXTO: As doenças inflamatórias intestinais (DII) são afecções inflamatórias crônicas de caráter recorrente, cujas taxas de incidência e prevalência têm aumentado, inclusive no Brasil. A longo prazo, são responsáveis por danos estruturais que impactam na qualidade de vida, morbidade e mortalidade dos pacientes. OBJETIVO: Avaliar o perfil dos médicos que atendem pacientes com DII, assim como as características deste atendimento, demandas não atendidas e dificuldades. MÉTODOS: Um questionário contendo 17 variáveis foi elaborado e enviado para médicos, selecionados a partir do cadastro da Comissão das Estaduais do Grupo de Estudos da Doença Inflamatória Intestinal do Brasil (GEDIIB), totalizando 286 médicos de 101 cidades brasileiras distribuídas por 21 estados e Distrito Federal. RESULTADOS: A maioria dos médicos que respondeu o questionário foram Gastroenterologistas e Coloproctologistas. Mais de 60% tinham até 20 anos de atuação na especialidade e 53,14% trabalhavam em três locais ou mais. A dificuldade no acesso ou liberação de medicamentos ficou evidenciada neste questionário, assim como a dificuldade no encaminhamento para profissionais não médicos que atuam em DII. Mais de 75% dos médicos relataram dificuldades para realização de enteroscopia por duplo balão e cápsula endoscópica, e 67,8% para realização da calprotectina. Em relação ao número de pacientes atendidos por cada médico, foi evidenciado que não há uma concentração de pacientes sob a responsabilidade de poucos médicos. O infliximabe e o adalimumabe foram os biológicos mais utilizados e ficou evidenciada prescrição maior de derivados de 5-ASA para retocolite ulcerativa quando comparada à doença de Crohn. Os corticoides foram prescritos para uma parcela menor de pacientes em ambas doenças. Os temas "falha a terapia biológica" e "novas drogas" foram referidos como aqueles com maior prioridade para discussão em eventos científicos. Em relação às possíveis diferenças entre cada região e o restante do país, os médicos da região Norte relataram maior dificuldade no acesso a exames complementares e os médicos da região Nordeste, maior dificuldade no acesso ou liberação de medicamentos. CONCLUSÃO: Os dados obtidos por meio deste estudo mostram o perfil do atendimento médico especializado em DII e podem se constituir em ferramenta útil para para elaboração de políticas governamentais e para sociedade brasileira como um todo.

RESUMO

OBJECTIVE: To quantify and compare the electromyographic activity of trunk and upper limb muscles in three different pullover exercises. METHODS: 15 healthy men, with at least two years of experience in resistance training, executed in random order six repetitions with 60% of 1 Maximum Repetition for three different pullover exercises: lying on a step with a barbell, grip 100% biacromial (E1); lying on a step with a barbell, grip 150% (E2); lying on a Swiss ball with a barbell, grip 100% (E3). Surface electromyography was recorded from the Deltoideus (Clavicular and Spinalis Pars), Pectoralis Major (Clavicular and Sternocostalis Pars), Serratus Anterior, Triceps Brachii (Long Head), Latissimus Dorsi, Infraspinatus, Rectus Abdominis, Obliquus Internus Abdominis and Transversus Abdominis. The normalized electromyogram of maximal voluntary isometric contraction of each muscle was calculated for each exercise. RESULTS: The most engaged muscles were Infraspinatus (51-53% Electromyogram maximal voluntary isometric contraction) and Posterior Deltoid (49-51% Electromyogram maximal voluntary isometric contraction). Surface electromyography activity was similar between the E1, E2 and E3 exercises. CONCLUSIONS: This study quantified muscular solicitation during pullover exercises performed with 60% Maximum Repetition. The muscles with higher level of activation were the Posterior Deltoid and the Infraspinatus, suggesting that pullover may be a valid option for strengthening the dynamic stabilizing muscles of shoulder joint in trained individuals. No significant differences in muscle electromyography intensity were observed when grip distance and trunk stabilization were altered, showing that these conditions do not influence muscle activation levels. However, the 1 Maximum Repetition was lower when the pullover was performed on a Swiss ball, suggesting that it is possible to obtain higher level of muscle recruitment with lower weights in unstable exercises


OBJETIVO: cuantificar y comparar la actividad electromiográfica de diez músculos en tres diferentes ejercicios de pullover. MÉTODO: 15 hombres sanos, con al menos dos años de experiencia en entrenamiento de resistencia, realizaron seis repeticiones al 60% de 1 Repetición Máxima en orden aleatorio para tres ejercicios de pullover diferentes: acostados en una tabla con mancuernas y agarre 100% biacromial (E1), acostados en una tabla con mancuernas, agarre 150% biacromial (E2) y acostado en una pelota suiza con mancuernas, agarre 100% biacromial (E3). Se registró la señal electromiográfica de superfície de Deltoides (anterior y posterior), Pectoral Mayor (clavicular y esternocostal), Serrato Anterior, Tríceps Braquial (porción externa), Dorsal Grande, Infraespinoso, Recto Abdominal, Oblicuo Interno y Transverso del Abdominal. Se calculó la Repetición Máxima para normalizar la señal electromiográfica de cada músculo y para cada ejercicio. RESULTADOS: los músculos más involucrados fueron el Infraespinoso (51-53% señal electromiográfica de superfície 1 Repetición Máxima) y el Deltoides Posterior (49-51% señal electromiográfica de superfície 1 Repetición Máxima). La actividad electromiográfica de superficie fue similar entre los ejercicios E1, E2 y E3. CONCLUSIONES: este estudio cuantificó las demandas musculares durante los ejercicios pullover realizados con un 60% de la Repetición Máxima. Los músculos con mayor nivel de activación fueron el Deltoides Posterior e Infraespinoso, lo que sugiere que el pullover puede ser una opción válida para fortalecer los músculos estabilizadores dinámicos de la articulación del hombro en individuos entrenados. No se observaron diferencias significativas en el nivel de la activación muscular cuando se modificó la distancia del agarre y la estabilización del tronco, lo que demuestra que estas condiciones no influyen en los niveles de activación muscular. Sin embargo, 1 Repetición Máxima fue menor cuando el pullover se realizó en una pelota suiza, lo que sugiere que es posible obtener un mayor nivel de reclutamiento muscular con pesos menores en ejercicios inestables

RESUMO

This study analyzed the physiological adjustments caused by the use of the Elevation training mask® (2.0), an airflow restriction mask (ARM) during continuous exercise. Eighteen physically active participants (12 men and 6 women) were randomized to two protocols: continuous exercise with mask (CE-ARM) and continuous exercise without mask (CE). Exercise consisted of cycling for 20 minutes at 60% of maximum power. Metabolic variables, lactate, and gas concentration were obtained from arterialized blood samples at pre and post exercise. Continuous expired gases and myoelectric activity of the quadriceps were performed at rest and during the test. We observed no reduction in oxygen saturation in CE-ARM, leading to lower pH, higher carbon dioxide, and greater hematocrit (all p <0.05). The expired gas analysis shows that the CE-ARM condition presented higher oxygen uptake and expired carbon dioxide concentrations (p <0.05). The CE-ARM condition also presented lower ventilatory volume, ventilatory frequency, and expired oxygen pressure (p <0.05). No changes in electromyography activity and lactate concentrations were identified. We conclude that using ARM does not induce hypoxia and represents an additional challenge for the control of acid-base balance, and we suggest the use of ARM as being suitable for respiratory muscle training.
