Abstract Background: Low functional health literacy in anticoagulated patients using warfarin has been widely discussed in medical literature. Objective: To identify the quality of oral anticoagulation (QOA) over time and to analyze the association between this variable and functional health literacy. Methods: Prospective cohort study conducted at an anticoagulation clinic (AC) in Minas Gerais, in a high-complexity hospital. The study included 81 patients, whose data were collected by direct consultation of medical records or by asking questions while patients were waiting for care. The QOA was assessed at 6, 9, 12, 15, and 18 months after the beginning of this study, and analyses of the association between this variable and functional health literacy were performed at the different time points. The QOA was identified by calculating the Therapeutic Time Range (TTR), with good quality being obtained with TTR values >59%. The incidence analysis of the TTR was performed for each of the five time points of the study through univariate Poisson regression. The significance level adopted in the statistical analysis was 5%. Results: Throughout the study, inadequate control of oral anticoagulation was observed, with only 20% of the patients showing persistent improvement in TTR values. No statistically significant association was identified at the different measurement times between TTR and functional health literacy. Conclusion: There was no direct association between the QOA and functional health literacy. However, the low incidence of persistent quality of anticoagulation in patients with low literacy suggests the development of specific educational actions for this subgroup of patients.

Abstract Background Time in therapeutic range (TTR) plays an important role in the effectiveness of anticoagulant therapy with vitamin K antagonists. Objective To identify factors associated with variation in TTR. Methods The study sites were anticoagulation clinics at two university hospitals in Minas Gerais, with a total of 1357 patients studied. TTR was calculated using the Rosendaal method. Binary logistic regressions were carried out with the study variables, followed by multiple regression with those that were significant for the model, adopting a significance level of 5%. Results The outpatient clinics presented different values in mean TTR; one corresponded to the expected percentage, while the other did not. Multiple regression identified the variable male sex as a protective factor in relation to TTR < 60% (odds ratio [OR]: 0.42; p = 0). Conclusion The identification of variables associated with inadequate TTR contributes to identifying weaknesses in the care process and implementing improvement actions in the hospitals studied.

Abstract Objective We aim to describe an experimental model for studying femoral fractures in rats after exposure to ionizing radiation, demonstrating a way to apply a substance for analysis, the method for patterning fracture and irradiation, and how to evaluate its effectiveness based on radiographic studies. Methods We used 24 rats divided into 2 groups of 12 animals each. The STUDY group was exposed to ionizing radiation and treated with saline solution, and the CONTROL group was not exposed to radiation and was treated with saline solution. All animals were subjected to standardized fracture of the right femur that was fixed with intramedullary wire. The efficiency of the bone union was assessed by radiographic exam. Results Fracture healing was more efficient in bones not exposed to ionizing radiation (p = 0.012). All fractures met the criteria of being simple, diaphyseal, transverse or short oblique. Conclusion The experimental model presented is an efficient alternative for the study of fractures in irradiated bones in rats.

Resumo Objetivo Nosso objetivo é descrever um modelo experimental para estudo de fraturas de fêmur em ratos após exposição a radiação ionizante, demonstrando uma forma de aplicação de uma substância para análise, o método de padronização de fratura e irradiação e a forma de avaliação de sua eficácia com base em estudos radiográficos. Métodos Utilizamos 24 ratos divididos em dois grupos de 12 animais cada. O grupo ESTUDO foi exposto à radiação ionizante e tratado com soro fisiológico, enquanto o grupo CONTROLE não foi exposto à radiação e foi tratado com soro fisiológico. Todos os animais foram submetidos à fratura padronizada do fêmur direito e sua fixação com fio intramedular. A eficácia da consolidação óssea foi determinada por exame radiográfico. Resultados A cicatrização de fraturas foi mais eficiente em ossos não expostos à radiação ionizante (p = 0,012). Todas as fraturas atenderam aos critérios de serem simples, diafisárias, transversas ou oblíquas curtas. Conclusão O modelo experimental apresentado é uma boa alternativa para o estudo de fraturas em ossos irradiados em ratos.

Resumo Objetivou-se avaliar os impactos da COVID-19 no rastreamento do câncer de mama no Brasil. Coletaram-se dados do Sistema de Informações Ambulatoriais referentes a “mamografia bilateral para rastreamento” de janeiro/2015 a dezembro/2021. As análises foram feitas por região e para o Brasil. Calculou-se a média de exames em cada mês do ano com base nos dados de 2015 a 2019, a qual foi comparada, mensalmente, com o quantitativo de exames em 2020 e 2021, obtendo-se a diferença bruta e percentual entre esses valores. A mesma análise foi realizada para o número total de exames em 2020 e 2021, individualmente, e para os dois anos em conjunto. Em 2020 houve quedas no número de exames que variaram de 25% (Norte) a 48% (Nordeste), culminando em 1,749 milhão de exames a menos no país (queda de 44%). Em 2021, a região Centro-Oeste apresentou quantitativo de exames 11% superior ao esperado, enquanto as demais regiões apresentaram quedas entre 17% (Norte) e 27% (Sudeste/Sul), culminando em negativo de 927 mil exames no país (redução de 23%). Na análise conjunta (2020/2021), encontraram-se reduções que variaram de 11% (Centro-Oeste) a 35% (Sudeste/Sul), culminando em negativo de 2,676 milhões de procedimentos no Brasil (queda de 33%).

Abstract The scope of this study was to evaluate the impacts of COVID-19 on breast cancer screening in Brazil. Data were collected from the Ambulatory Information System relating to “bilateral screening mammography” from January/2015 to December/2021. Analyses were performed by region and for Brazil. The average of exams in each month of the year was calculated based on 2015-2019 data, which was compared, monthly, with the number of exams in 2020 and 2021, obtaining the gross and percentage difference between these values. The same analysis was performed for the total number of exams in 2020 and 2021, individually, and for the two years combined. In 2020 there were reductions in the number of exams, which ranged from 25% (North) to 48% (Northeast), resulting in 1.749 million fewer exams than expected in the country (a drop of 44%). In 2021, the Midwest region presented a number of exams 11% higher than expected, while the other regions presented drops between 17% (North) and 27% (Southeast/South), resulting in 927 thousand exams fewer than expected in Brazil (reduction of 23%). In the joint analysis (2020/2021), reductions varied by region from 11% (Midwest) to 35% (Southeast/South), culminating in 2.676 million exams fewer than expected in Brazil (reduction of 33%).

Objective: to retrospectively evaluate and compare the proportions of complications and radiographic findings of two- and three-part proximal humerus fracture osteosynthesis with two treatment methods: third-generation locked intramedullary nail and locked plate. Methods: 46 patients with a mean age of 58.9±16.6 years were evaluated between January 2020 and January 2021. In sixteen cases (34.8%), an intramedullary nail was used, and in thirty cases (65 .2%), the proximal humerus locked plate. The evaluation used included the rate of complications with a minimum follow-up of 6 months postoperatively and radiographic evaluation. Results: there was no significant difference between the groups regarding the proportion of complications (nail group 18.8%, plate group 13.3%; p=0.681). The nail group showed less residual loss in varus (cervicodiaphyseal angle, nail group 132.1º±2.3º, plate group 123.8º±10.1º; p&lt;0.001). In the plaque group, women had a lower value (1.43±0.22) of the tuberosity-deltoid index (DTI) compared to men (1.58±0.11) (p=0.022). Conclusions: in the short-term follow-up, osteosynthesis, with locked plate and intramedullary nail, did not show differences in the proportions of complications. The nail group showed less change in the post-operative cervicodiaphyseal angle, however, there were two serious complications with cut out and varus deviation requiring a new surgical approach in the nail group.

ABSTRACT Objective: To evaluate and compare the proportions of complications and radiographic findings of osteosynthesis of 2- and 3-part proximal humerus fractures with two methods of treatment: third-generation antegrade nailing and locking plate. Methods: 46 patients with a mean age of 58.9 ± 16.6 years between January 2020 and January 2021 were evaluated. In sixteen cases (34.8%), antegrade nailing was used, and in thirty cases (65, 2%), a locking proximal humerus plate. The method used included the rate of complications with a minimum follow-up of 6 months after surgery and radiographic evaluation. Results: There was no difference between the groups regarding the proportion of complications (nail group 18.8%, plate group 13.3%; p = 0.681). The nail group had less residual varus loss (cervicodiaphyseal angle nail group with 132.1º ± 2.3º, plate group 123.8º ± 10.1º; p < 0.001). In the plate group, women had the lowest value (1.43 ± 0.22) of the deltoid tuberosity index (DTI) compared to men (1.58 ± 0.11) (p = 0.022). Conclusion: Osteosynthesis, with a locking plate and antegrade nailing, did not show differences in the proportion of complications. The nail group had less change in the postoperative cervicodiaphyseal angle, however, there were two serious complications with screw cut-out and varus deviation, requiring surgical reapproach.

Resumo A sífilis, uma infecção vertical e sexualmente transmissível, curável e prevenível, é um problema de saúde pública no Brasil. Métodos diagnósticos e tratamentos são importantes no controle da doença. A pandemia de Covid-19 causou atrasos em diagnósticos e no tratamento na atenção primária em várias doenças e em diversos países, pois interrompeu padrões usuais de atendimento à saúde. O objetivo do estudo é identificar se houve menor número de procedimentos diagnósticos e de tratamento realizados para sífilis nos primeiros sete meses de 2020, comparativamente à média dos mesmos meses entre 2016 e 2019, no Brasil e nas unidades federativas. A redução no número de procedimentos seria um indicativo de atraso no diagnóstico, na detecção e no tratamento da sífilis em 2020. Foram utilizadas informações disponibilizadas no Sistema de Informações Ambulatoriais (SIA/SUS). Os achados para o Brasil indicaram queda de 1/3 nos procedimentos de diagnóstico e de tratamento referentes à sífilis nos sete primeiros meses do ano da pandemia, comparados com a média dos sete primeiros meses nos quatro anos anteriores (2016-2019). Indicadores mostram diferenças importantes por unidades da federação, apontando para maiores quedas proporcionais nos volumes de procedimentos no Norte e Nordeste, com ênfase nos estados do Maranhão, Roraima, Pará, Bahia, Rio Grande do Norte, Amazonas, Pernambuco e Amapá.

Abstract Syphilis, a vertical and sexually transmitted infection, curable and preventable, is a public health problem in Brazil. Diagnostic methods and treatments are important in controlling the disease. The COVID-19 pandemic caused delays in diagnosis and lack of treatment in primary care in several diseases and in several countries, as the pandemic disrupted usual health care standards. The aim of the study was to identify whether there were fewer diagnostic and treatment procedures performed for syphilis in the first seven months of 2020, compared to the average for the same months between 2016 and 2019, in Brazil and Federative Units. The reduction in the number of procedures would be indicative of a delay in the diagnosis, detection and treatment of syphilis in 2020. Information used came from the Outpatient Information System (SIA / SUS). The findings for Brazil indicated a 1/3 drop in diagnosis and treatment procedures for syphilis in the first seven months of the year of the COVID-19 pandemic, compared with the first seven months of the previous four years (2016-2019). Indicators showed important differences by Federation Units, pointing to greater proportional decrease in the volume of procedures in the North and Northeast, with an emphasis on Maranhão, Roraima, Pará, Bahia, Rio Grande do Norte, Amazonas, Pernambuco and Amapá.

La reducción del número de procedimientos indicaría indicativo de un retraso en el diagnóstico, la detección temprana y el tratamiento de la sífilis en 2020. Para ello se utilizó la información disponible en el Sistema de Información Ambulatoria (SIA/SUS). Los hallazgos indicaron una caída de un tercio en los procedimientos de diagnóstico y tratamiento de la sífilis en los primeros siete meses del año de la pandemia de Covid-19 para Brasil, en comparación con los primeros siete meses de los cuatro años anteriores (2016-2019). Los indicadores mostraron diferencias importantes por unidades de la Federación, apuntando a mayores caídas proporcionales en el volumen de trámites en el Norte y Nordeste, con énfasis en Maranhão, Roraima, Pará, Bahia, Rio Grande do Norte, Amazonas, Pernambuco y Amapá.

ABSTRACT Background: Syphilis is a chronic infectious disease that has created challenging situations for humanity for centuries. Transmission can occur sexually or vertically, with great repercussions on populations, particularly among women and children. The present study presents information on the main burden imposed by syphilis generated by the Global Burden of Disease (GBD) Study 2019 for Brazil and its 27 federated units. Methods: We described the metrics of incidence, deaths, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs), standardized by age and per 100,000 inhabitants, from 1990 to 2019, and we compared the disease burden between the years 1990 and 2019. Results: In Brazil, the disease burden increased between 2005 and 2019 for all metrics. Although a higher incidence of syphilis was found among women in 2019, DALYs [YLLs (males: 15.9%; females: 21.8%), YLDs (males: 25.0%; females: 50.0%), and DALYs (males: 16.2%; females: 22.4%)] were higher among men. In 2019, the highest DALY rate per 100,000 inhabitants was observed in individuals aged above 50 years. The State of Maranhão presented the highest values of DALYs {1990: 165.2 [95% uncertainty interval (UI) 96.2-264.4]; 2005: 43.8 [95% UI 30.3-62.4]; 2019: 29.1 [95% UI 19.8-41.1]} per 100,000 inhabitants in the three years analyzed. Conclusions: The burden of syphilis has increased in recent years. Men presented higher DALYs, although the incidence of the disease was higher in women. Syphilis affects a large number of people across all age groups, causing different degrees of disability and premature death (DALYs).
