RESUMO

BACKGROUND: Patients with Hemophilia are continually monitored at treatment centers to avoid and control bleeding episodes. This study estimated the direct and indirect costs per patient with hemophilia A in Brazil and evaluated the cost variability across different age groups. METHODS: A prospective observational research was conducted with retrospective data collection of patients assisted at three referral blood centers in Brazil. Time-driven Activity-based Costing method was used to analyze direct costs, while indirect costs were estimated based on interviews with family and caregivers. Cost per patient was analyzed according to age categories, stratified into 3 groups (0-11;12-18 or older than 19 years old). The non-parametric Mann-Whitney test was used to confirm the differences in costs across groups. RESULTS: Data from 140 hemophilia A patients were analyzed; 53 were 0-11 years, 29 were 12-18 years, and the remaining were older than 19 years. The median cost per patient per year was R$450,831 (IQR R$219,842; R$785,149; $174,566), being possible to confirm age as a cost driver: older patients had higher costs than younger's (p = 0.001; median cost: 0-11 yrs R$299,320; 12-18 yrs R$521,936; ≥19 yrs R$718,969). CONCLUSION: This study is innovative in providing cost information for hemophilia A using a microcosting technique. The variation in costs across patient age groups can sustain more accurate health policies driven to increase access to cutting-edge technologies and reduce the burden of the disease.

RESUMO

Background: Various instruments have been used to assess health-related quality of life (HRQoL) in children and adolescents with hemophilia A. Objective: We systematically reviewed the literature to summarize HRQoL measurement instruments and outcomes in this population. Methods: MEDLINE, Embase, Cochrane CENTRAL, and LILACS databases were searched. Studies published from 2010 to 2021, reporting HRQoL assessed by generic or hemophilia-specific instruments in individuals aged 0 to 18 years were included. Two independent reviewers performed screening, selection, and data abstraction. Data were meta-analyzed using the generic inverse variance method with the random-effects model for single-arm studies reporting instrument-specific mean total HRQoL scores. Prespecified subgroup meta-analyses were performed. Heterogeneity among studies was assessed using the I 2 statistic. Results: Six instruments were identified in 29 studies meeting the following inclusion criteria: 4 generic instruments (PedsQL [5 studies], EQ-5D-3L [3 studies], KIDSCREEN-52 [1 study], and KINDL [1 study]) and 2 hemophilia-specific instruments (Haemo-QoL [17 studies] and CHO-KLAT [3 studies]). The overall risk of bias was moderate to low. There was a substantial variability in the primary outcome (mean total HRQoL score) among studies using the same instrument (Haemo-QoL), with scores ranging from 24.10 to 89.58 on a scale from 0 to 100 (higher scores indicating higher HRQoL). Meta-regression with 14 studies using the Haemo-QoL questionnaire demonstrated that 79.34% (R 2 ) of the observed 94.67% total heterogeneity (I 2 ) was explained by the proportion of patients receiving effective prophylactic treatment. Conclusion: HRQoL assessment in young people with hemophilia A is heterogeneous and context specific. The proportion of patients on effective prophylactic treatment is positively correlated with HRQoL. The review protocol was registered prospectively with PROSPERO (CRD42021235453).

RESUMO

Objective: To describe the annual medical direct costs per hemophilia A (HA) patient in the Brazilian public healthcare system (SUS) and to understand and describe the patients' hospital journey, demographical characteristics, and the procedures in the. Methods: This retrospective analysis of DataSUS databases. Data from individuals with registries of HA treatment were gathered between January 1st, 2018, and June 30th, 2021. Besides the D66 ICD-10th code (HA), were also considered the occurrence of some procedures like factor VIII dosage and by-pass therapy dispensation or administration as inclusion criteria. Exclusion criteria were occurrence of factor IX dispensation and female patients were excluded, among others. A record linkage using sociodemographic characteristics was conducted to identify unique patients. Results: Were identified 2,298 individuals underwent ambulatory and 1,018 underwent hospital treatments. The results show that most patients are from the Southeast region of the country, white and middle-aged individuals. The median cost of HA treatment per patient-year was BRL 90.36 for ambulatory care and BRL 1,015.31 for hospital care procedures. The costs were significantly higher for more severe patients and for those between 12 and 18 years old (BRL 1,974.75 and BRL 1,049.09, respectively). Conclusion: The evidence demonstrated encourages the implementation of policies aiming to improve the quality of care provided to patients with HA. Providing referral centers for hemophiliac patients is primordial for the success of the treatment and can result in efficiency.

RESUMO

Objective: Understanding unmet needs related to hemophilia A management in Brazil is critical for supporting decision-making. Methods: A modified Delphi consensus panel was conducted. Hematologists with extensive experience treating hemophilia in the Brazilian Public Health System were invited to answer questions regarding indicators of severe hemophilia prophylaxis effectiveness, emicizumab treatment indications, and bypassing agents used to reduce bleeding in patients with inhibitors, immune tolerance induction (ITI) use, and adherence. The consensus was defined as ≥75% of votes in Round 1 or using a 5-point Likert-type scale (1 = strongly disagree, 2 = disagree, 3 = neither agree nor disagree, 4 = agree, and 5 = strongly agree) in Round 2, which included questions not reaching minimum cut-off in the first step. Results: Nine expert panelists with extensive experience in the Brazilian Public Health System participated. The panel reached an agreement on recommendations about prophylaxis, bleeding treatment patterns, and bleeding sites. From patients' perspectives, venous access and infusion frequency were the most significant barriers to improving patient treatment. According to most experts, emicizumab will not replace ITI or long-term factor VIII therapy. Still, emicizumab was thought to be a good therapeutic option for patients with difficult venous access, patients requiring central venous access, in the presence of inhibitors, or patients experiencing infusion-related pain. Conclusion: The information gleaned from this study may be helpful to both decision-makers and those in charge of developing healthcare economic models for the treatment of hemophilia A in Brazil.

Objetivo: É fundamental entender as necessidades não atendidas relacionadas ao manejo da hemofilia A no Brasil. Métodos: Foi conduzido um painel Delphi modificado. Foram convidados hematologistas com vasta experiência no tratamento de hemofilia no SUS para responder a perguntas sobre indicadores de eficácia da profilaxia, indicações de tratamento com emicizumabe, uso de agentes de bypass, uso de indução de tolerância imunológica (ITI) e adesão. O consenso foi definido como ≥75% dos votos na rodada 1 ou usando uma escala do tipo Likert de 5 pontos (1 = discordo totalmente, 2 = discordo, 3 = não concordo nem discordo, 4 = concordo e 5 = concordo totalmente) na segunda rodada, que incluiu questões que não atingiram o corte mínimo na primeira etapa. Resultados: Nove especialistas participaram e houve consenso sobre recomendações para profilaxia, padrões de tratamento de sangramento e locais de sangramento. O acesso venoso e a frequência da infusão foram identificados como as barreiras mais significativas para melhorar o tratamento do paciente. De acordo com a maioria, emicizumabe não substituirá a ITI ou tratamento com fator VIII de longo prazo. Emicizumabe foi considerado uma boa opção terapêutica para

RESUMO

Permethrin (PERM) is a member of the class I family of synthetic pyrethroids. Human use has shown that it affects different systems, with wide health dysfunctions. Our aim was to determine bioenergetics, neuroinflammation and morphology changes, as redox markers after subacute exposure to PERM in rats. We used MDA determination, protein carbonyl assay, mitochondrial O2 consumption, expression of pro-inflammatory cytokines and a deep histopathological analysis of the hippocampus. PERM (150 mg/kg and 300 mg/kg body weight/day, o.v.) increased lipoperoxidation and carbonylated proteins in a dose-dependent manner in the brain regions. The activities of antioxidant enzymes glutathione peroxidase, reductase, S-transferase, catalase, and superoxide dismutase showed an increase in all the different brain areas, with dose-dependent effects in the cerebellum. Cytokine profiles (IL-1ß, IL-6 and TNF-α) increased in a dose-dependent manner in different brain tissues. Exposure to 150 mg/kg of permethrin induced degenerated and/or dead neurons in the rat hippocampus and induced mitochondrial uncoupling and reduction of oxidative phosphorylation and significantly decreased the respiratory parameters state 3-associated respiration in complex I and II. PERM exposure at low doses induces reactive oxygen species production and imbalance in the enzymatic antioxidant system, increases gene expression of pro-inflammatory interleukins, and could lead to cell damage mediated by mitochondrial functional impairment.

RESUMO

Objective: To describe the healthcare resource utilization (HCRU) related to patients with spinal muscular atrophy (SMA) treated at the Brazilian Unified Health System (SUS) since 2015 according to age-groups. Methods: This study analyzed outpatient and inpatient data for SMA patients from the Brazilian Unified Health System database (DATASUS) from January 2015 to September 2020. Data were collected from patients with ICD-10 codes G12.0 (Infantile spinal muscular atrophy, type I [Werdnig-Hoffman]) or G12.1 (Other inherited spinal muscular atrophy), plus with at least one claim of nusinersen OR at least one claim of any SMA-related procedure groups codes since 2010. SMA-related procedures were defined based on collaborative work involving authors from medical boarding composed by physicians from SUS. Results: In total, 3,775 patients with SMA fulfilled the eligibility criteria. Physiotherapy changed from 11.34 (2.49 ­ 24.40) procedures PPPY in the 0 - 6-month old group to 3.30 (0.84 ­ 11.76) procedures PPPY in the > 36-month old group. The median of orthosis was 1.64 (0.66 ­ 3.41) procedures PPPY in the 0 ­ 6-month old group and 0.63 (0.34 ­ 1.33) PPPY in the > 36-month-old group. Exams were primarily performed for younger groups (0 ­ 6 months and > 6 ­ 18 months). The percentage of patients that needed some ventilatory care seems greater, and the speech therapy and the use of nusinersen seem lower along with age. Conclusion: This study has demonstrated important HCRU at the SUS setting with SMA patients. In addition, our results highlight the need to implement evidence-based strategies to manage SMA patients and drive cost savings for the health care system.

Objetivo: Descrever a utilização de recursos em saúde de pacientes com atrofia muscular espinhal (AME) no Sistema Público de Saúde Brasileiro (SUS) desde 2015, de acordo com a faixa etária. Métodos: Analisaram-se os dados hospitalares e ambulatoriais de pacientes com AME no DATASUS de janeiro de 2015 a setembro de 2020. Foram incluídos pacientes com código de CID-10 G12.0 (atrofia muscular espinhal infantil tipo I ­ Werdning-Hoffman) ou G12.1 (outras atrofias medulares espinhais hereditárias) com pelo menos um registro utilizando o código de nusinersena ou o código de procedimento relacionado à doença desde 2010. Os procedimentos relacionados à doença foram definidos por meio de trabalho colaborativo entre autores, incluindo três autores médicos que atuam no SUS. Resultados: No total, 3.775 pacientes com AME preencheram os critérios de elegibilidade. Procedimentos de fisioterapia passaram de 11,34 (2,49 ­ 24,40) por paciente por ano (PPPY) no grupo 0 ­ 6 meses para 3,30 (0,84 ­ 11,76) PPPY no grupo > 36 meses. A mediada de procedimentos de órteses foi de 1,64 (0,66 ­ 3,41) PPPY no grupo 0 ­ 6 meses para 0,63 (0,34­ 1,33) PPPY no grupo > 36 meses. Exames foram realizados principalmente por pacientes mais jovens (0 ­ 6 meses e > 6 ­ 18 meses). A porcentagem de pacientes que realizaram procedimentos ventilatórios parece aumentar ao longo da idade, já a fonoterapia e o uso de nusinersena parecem reduzir. Conclusão: Este estudo demonstra uma importante utilização de recursos em saúde no SUS pelos pacientes com AME e destaca a necessidade de implementação de estratégias baseadas em evidência para gerenciar esses pacientes e o uso de recursos no sistema de saúde

RESUMO

Traumatic brain injury (TBI) induces two types of brain damage: primary and secondary. Damage initiates a series of pathophysiological processes, such as metabolic crisis, excitotoxicity with oxidative stress-induced damage, and neuroinflammation. The long-term perpetuation of these processes has deleterious consequences for neuronal function. However, it remains to be elucidated further whether physiological variation in the brain microenvironment, depending on diurnal variations, influences the damage, and consequently, exerts a neuroprotective effect. Here, we established an experimental rat model of TBI and evaluated the effects of TBI induced at two different time points of the light-dark cycle. Behavioral responses were assessed using a 21-point neurobehavioral scale and the cylinder test. Morphological damage was assessed in different regions of the central nervous system. We found that rats that experienced a TBI during the dark hours had better behavioral performance than those injured during the light hours. Differences in behavioral performance correlated with less morphological damage in the perilesional zone. Moreover, certain brain areas (CA1 and dentate gyrus subregions of the hippocampus) were less prone to damage in rats that experienced a TBI during the dark hours. Our results suggest that diurnal variation is a crucial determinant of TBI outcome, and the hour of the day at which an injury occurs should be considered for future research.

RESUMO

Dengue is an important arthropod-borne viral disease in terms of morbidity, mortality, economic impact and challenges in vector control. Benchmarks are expensive, time consuming and require trained personnel. Preventing dengue complications with rapid diagnosis has been based on the testing of easy-to-perform optimized immunochromatographic methods (ICT). This is a systematic meta-analysis review of the diagnostic accuracy of IgA, NS1, IgM and/or IgG ICT studies in suspected cases of acute or convalescent dengue, using a combination of RT-PCR, ELISA NS1, IgM IgG or viral isolation as a reference standard. This protocol was registered in PROSPERO (CRD42014009885). Two pairs of reviewers searched the PubMed, BIREME, Science Direct, Scopus, Web of Science, Ovid MEDLINE JBrigs, SCIRUS and EMBASE databases, selected, extracted, and quality-assessed by QUADAS 2. Of 3,783 studies, we selected 57, of which 40 in meta-analyses according to the analyte tested, with high heterogeneity (I2 > 90%), as expected for diagnostic tests. We detected higher pooled sensitivity in acute phase IgA (92.8%) with excellent (90%) specificity. ICT meta-analysis with NS1/IgM/IgG showed 91% sensitivity and 96% specificity. Poorer screening performance was for IgM/IgG ICT (sensitivity = 56%). Thus, the studies with NS1/IgM/IgG ICT showed the best combined performance in the acute phase of the disease.

RESUMO

ABSTRACT Background: Although performance of rapid immunochromatographic tests (RITs) for dengue virus (DENV) serotypes 1, 2 and 3 is relatively settled, evidence on accuracy of RITs for DENV-4 are based on studies with small sample sizes and with discrepant results. Objectives: To assess accuracy and inter-observer agreement of RITs targeting dengue nonstructural protein-1 (NS1) antigen - Dengue NS1-Bioeasy™, Dengue NS1 Ag Strip-Bio-Rad™, IVB Dengue Ag NS1-Orangelife™ and Dengue NS1-K130-Bioclin™ in DENV-4 samples. Methods: Study sample (n = 324) included adults presenting at an emergency unit in Rio de Janeiro, Brazil, with fever of ≤72 h and two or more dengue symptoms. A serum sample from each patient was tested by each RIT. A positive reverse-transcription polymerase chain reaction was considered as the reference standard for dengue diagnosis. The diagnostic parameters analyzed for each RIT were sensitivity, specificity, positive and negative predictive values, and likelihood ratios. Each RIT was read by homogeneous (two junior nurses) or heterogeneous (one junior nurse and one senior biologist) pairs. Agreement was estimated by simple kappa with 95% confidence interval, positive (Ppos) and negative (Pneg) proportion concordance and prevalence and bias adjusted kappa, rated from poor (k < 0.0) to almost perfect (0.8 < k < 1.0), and perfect (k = 1). Results: NS1 RITs for DENV-4 diagnosis showed high specificity (95.9%-99.4%), but low sensitivity (14.7%-45.4%). Bioeasy™ had the best performance, with a positive likelihood ratio of 26.0 (95% CI: 8.4;81.0). Inter-observer agreement was almost perfect for all evaluated RITs. Mismatches in confirmed dengue were more common for the Bioclin™ (Ppos 88.3-90.0 %) and Orangelife™ (Ppos 91.7-94.1 %) tests. Conclusions: For DENV-4, the tested RITs had high specificity, but lower sensitivity compared to published results for other serotypes. They should not be used for screening purposes. Different brands may have very different performances. This should be considered upon deciding of using RITs in DENV-4 outbreaks.
