Abstract Diabetes mellitus (DM) is a major cause of chronic kidney disease (CKD) and changes in lipoprotein. Literature data suggest that cholesterol associated with high-density lipoprotein (HDLc) plays a protective role against albuminuria and diabetic nephropathy. These factors are related with changes in serum apolipoproteins such Apo A-I. This work aims to evaluate the correlation of apolipoprotein A-I with renal function in diabetic outpatients. Samples were collected from 281 outpatients for analyses of glycated hemoglobin (HbA1c), serum creatinine (SCr), urea (BUN), cholesterol (TC), triglycerides (TG), HDL-cholesterol (HDLc) and estimation of glomerular filtration rate (eGFR). Urinary samples were obtained to assess urine albumin creatinine ratio (UACR). Triglyceride-glucose index (TyG) was calculated to estimate insulin resistance. The mean age was 61,5 ± 16,4 years. Most patients were female, Afro-Mestizo and over 50 years of age. Pearson's revealed negative correlation of creatinine with HDLc and Apo A-I. There was a correlation of eGFR with HbA1c, TG and HDLc. TyG presented a negative correlation with Apo A-I and HDLc. The highest quartiles of UACR presented the highest TyG and the lowest Apo A-I. In conclusion, Apo A-I indicated an association with insulin resistance and changes in renal function parameters, especially as a factor associated with the onset of albuminuria, with a better predictive potential than the HDLc.

Abstract The objective was to assess the prevalence of bullying victimization and associated factors among adolescents in the city of Pelotas, Rio Grande do Sul. A cross-sectional school-based study was conducted with 795 ninth grade students from 25 urban municipal schools linked to the School Health Program. Bullying was assessed using questions that addressed the occurrence, frequency, location, type of violence suffered and how much it bothers the victims. Gross and adjusted analyses were performed by Poisson regression. Approximately 71% of the students reported having suffered bullying, and school was the location of greatest occurrence (86.7%). Among the types of aggression suffered, “nicknames” was the most recurrent complaint (88.4%), followed by exclusion or isolation (26.6%). Victimization was more frequent among girls (PR 1.13; 95%CI 1.02-1.27), students with non-white skin color/race (PR 1.16; 95%CI 1.05-1.29), who have already tried tobacco (PR 1.14; 95%CI 1.03-1.27), dissatisfied (PR 1.42; 95%CI 1.27-1.58) or indifferent (PR 1.21; 95%CI 1.02-1.43) about their bodies, and who were overweight (PR 1.15; 95%CI 1.04-1.27). The results show that bullying is a frequent practice in the school environment, pointing to the need for educational practices aimed at reducing and preventing this type of violence.

Os resultados mostram que o bullying é uma prática frequente no ambiente escolar, apontando para a necessidade de práticas educativas voltadas para a redução e prevenção desse tipo de violência.

Resumen: La ingesta excesiva de sodio es uno de los principales problemas de salud pública en todo el mundo, y la identificación de las fuentes alimentarias y tendencias temporales en su consumo son esenciales para desarrollar políticas efectivas de reducción de sodio. Este estudio tiene como objetivo actualizar las estimaciones de la ingesta de sodio y sus fuentes alimentarias en Brasil según el sistema de clasificación NOVA. Los registros de compras de alimentos en el período de 7 días de familias de las Encuestas de Presupuestos Familiares de Brasil de 2002-2003, 2008-2009 y 2017-2018 se convirtieron en nutrientes utilizando tablas de composición de alimentos. La disponibilidad media se estimó en 2.000kcal/día. El promedio diario de sodio disponible para el consumo en los hogares brasileños aumentó de 3,9 a 4,7g por 2.000kcal, entre 2002-2003 y 2017-2018, más del doble de los niveles de ingesta recomendados de este nutriente. Entre 2002-2003 y 2017-2018, los ingredientes culinarios procesados, incluida la sal de mesa, representaron la mayor fuente de sodio, aunque su participación en el sodio dietético se redujo en un 17% (del 66,6% al 55%), mientras que el porcentaje de sodio dietético de los alimentos procesados aumentó un 20,3% y de los alimentos ultraprocesados aumentó un 47,6% (11,3% a 13,6% y 17% a 25,1%, respectivamente). En conclusión, la disponibilidad total de sodio en los hogares sigue siendo alta y ha aumentado a lo largo del tiempo en Brasil, pero la proporción de diferentes fuentes dietéticas de sodio ha cambiado gradualmente.

Abstract: Excessive sodium intake is a major global public health issue and the identification of dietary sources and temporal trends in its consumption are a key to effective sodium reduction policies. This study aims to update estimates of sodium intake and its dietary sources in Brazil according to the NOVA food classification system. Records of 7-day food purchases of households from the Brazilian Household Budgets Survey of 2002-2003, 2008-2009, and 2017-2018 were converted into nutrients using food composition tables and the mean availability was estimated per 2,000kcal/day. Mean daily sodium available for consumption in Brazilian households has increased from 3.9 to 4.7g per 2,000kcal, from 2002-2003 to 2017-2018, over twice the recommended levels of sodium intake. From 2002-2003 to 2017-2018, the processed culinary ingredients, including table salt, represented the largest dietary source of sodium, although their participation in dietary sodium was reduced by 17% (66.6% to 55%), while the percentage of dietary sodium from processed foods increased by 20.3% and from ultra-processed foods increased by 47.6% (11.3% to 13.6% and 17% to 25.1%, respectively). In conclusion, the total household sodium availability remains high and has increased over time in Brazil, yet the participation of different dietary sources of sodium have gradually changed.

ABSTRACT: Acacia mearnsii De Wild. (Black wattle) is a forest species with great social and economical importance for the southern region of Brazil. This species has multifunctional characteristics, being cultivated to produce tannin, cellulose and energy. This research identified black wattle genotypes with competence for adventitious rooting for mini-cutting propagation. Single-bud mini-cuttings were treated with IBA at a concentration of 2000 mg L-1. After 30 days of cultivation in a humid chamber, the mini-cuttings were evaluated for percentages of survival, rooting, number of roots, average length of the three largest roots, and the number of mini-cuttings rooted per mini-stump. The identification of the best genotypes was performed with the Selegen REML/BLUP software. Selection between and within black wattle progenies can be performed based on the number of rooted mini-cuttings, making it possible to select genotypes with high competence for adventitious rooting while maintaining genetic variability for new selection cycles to develop clones for vegetative propagation by mini-cutting.

ABSTRACT Chrysanthemum (Dendranthema grandiflora) is the second most produced and commercialized ornamental plant in the world. Measuring leaf area through non-destructive methods is fundamental for studies on its growth and production. The estimation of leaf area by linear dimensions of the leaves can be a strategy for this purpose. The objective of this study was to find allometric equations to estimate the leaf area of chrysanthemum. The linear, linear without intercept, quadratic, cubic, power, and exponential regression models were used for the analysis. The choice of equations was based on the highest coefficients of determination. The non-destructive method using allometric models has accuracy for estimating the leaf area (LA) of chrysanthemum from the product between leaf length (L) and leaf width (W). The LA of chrysanthemum can be estimated using the equation ŷ = 0.6611*LW0.9490 (L - leaf length; W - leaf width). This equation will allow researchers and producers to determine leaf area non-destructively.

RESUMO O crisântemo (Dendranthema grandiflora) é a segunda planta ornamental mais produzida e comercializada no mundo. A medição da área foliar por métodos não destrutivos é fundamental para estudos sobre seu crescimento e produção. A estimativa da área foliar por dimensões lineares das folhas pode ser uma estratégia para este fim. O objetivo deste estudo foi encontrar equações alométricas para estimar a área foliar do crisântemo. Os modelos de regressão linear, linear sem intercepto, quadrático, cúbico, potência e exponencial foram utilizados para a análise. A escolha das equações foi baseada nos maiores coeficientes de determinação. O método não destrutivo por meio de modelos alométricos tem acurácia para estimar a área foliar (AF) do crisântemo a partir do produto entre o comprimento da folha (C) e a largura da folha (L). A AF do crisântemo pode ser estimada pela equação ŷ = 0,6611*CL0,9490 (C - comprimento da folha; L - largura da folha). Essa equação permitirá que pesquisadores e produtores determinem a área foliar de forma não destrutiva.

The tomato (Solanum lycopersicon L.) crop has great economic relevance, being one of the most processed agricultural products worldwide. Some pesticides are chemically stable and can remain in food even after processing. In this context, the objective of this work was to analyze food products derived from tomatoes (extract, sauce and ketchup), regarding the levels of pesticide residues. Fifteen samples were acquired from Vale do Jaguaribe, Ceará, Brazil. Six pesticides (bifenthrin, chlorothalonil, chlorpyrifos, cyfluthrin, pyriproxyfen, trifluralin) authorized by Agência Nacional de Vigilância Sanitária (Anvisa) for tomato cultivation were selected for the study. QuEChERS (quick, easy, cheap, effective, rugged, safe) extraction and gas chromatography coupled to mass spectrometry (GC-MS) were used in method validation, according to the recommendations of SANTE 11312/2021 guidelines. Statistical analyses of linearity showed that the six pesticides studied were classified as heterocesdastic. Limits of detection (LOD) and quantification (LOQ) values (0.01-0.03 and 0.03-0.10 mg kg-1, respectively) were below the established maximum residue limits (MRLs) for tomatoes. Accuracy and precision (78-121 and 2.3-16.7%, respectively) were satisfactory. The results indicated that among the 15 analyzed samples, one active ingredient was detected (0.05 mg kg-1) in a tomato sauce sample, lower than MRLs (Anvisa 0.15 mg kg-1 and FAO 0.3 mg kg-1). The results show the relevance of monitoring pesticide residues in tomato-derived products and the validation of new methodologies for food control.

Abstract Introduction: recent studies have suggested the use of neck circumference as a parameter capable of identifying risks of cardiometabolic complications and the accumulation of truncal fat caused by both antiretroviral therapy and the lifestyle of people with the human immunodeficiency virus (HIV). Objective: to investigate the relationship between neck circumference and anthropometric indicators and to assess cardiometabolic risk and truncal obesity through proposed cut-off points. Methods: cross-sectional study including 233 people with HIV. Demographic, socioeconomic, lifestyle and clinical data were collected using a structured questionnaire. The anthropometric evaluation included: weight, height, body mass index (BMI) measurements; waist (WC), neck (NC), arm and arm muscle circumferences; triceps and subscapular skinfolds and their sum. ROC curves were constructed to determine the accuracy of NC in predicting cardiometabolic risk in people living with HIV. Results: the sample was 57.5 % male, with a mean age of 38.4 years (95 % CI: 37.2-39.7 years). NC showed a positive and significant correlation with all anthropometric variables analyzed (p < 0.05), and a higher correlation strength with WC and BMI. The NC cut-off point selected as a predictor of risk of cardiac metabolic complications and truncal obesity in women was ≥ 32.4 cm, considering both WC and BMI. For men, the NC cut-off points were different when considering WC (≥ 39.6 cm) and BMI (≥ 38.1 cm) as a reference. It is worth noting that NC performed well in ROC curve analysis for men, while in women it was a poor performance. Conclusion: NC proved to be a promising indicator in the assessment of nutrition and health of people living with HIV, especially in men.

Resumen Introducción: estudios recientes han sugerido el uso de la circunferencia del cuello como parámetro capaz de identificar los riesgos de complicaciones cardiometabólicas y la acumulación de grasa troncal causados tanto por la terapia antirretroviral como por el estilo de vida de las personas con el virus de la inmunodeficiencia humana (VIH). Objetivo: investigar la relación entre la circunferencia del cuello y los indicadores antropométricos y evaluar el riesgo cardiometabólico y la obesidad troncal a través de los puntos de corte propuestos. Métodos: estudio transversal que incluyó a 233 personas con VIH. Se recogieron datos demográficos, socioeconómicos, de estilo de vida y clínicos mediante un cuestionario estructurado. La evaluación antropométrica incluyó: medidas de peso, altura, índice de masa corporal (IMC); circunferencias de cintura (CC), cuello (CN), brazo (CA) y músculo del brazo (MCB); pliegues cutáneos del tríceps y subescapular y su suma. Se construyeron curvas ROC para determinar la precisión de la CN en la predicción del riesgo cardiometabólico en personas que viven con el VIH. Resultados: el 57,5 % de la muestra eran varones, con una edad media de 38,4 años (IC 95 %: 37,2-39,7 años). La CN mostró una correlación positiva y significativa (p < 0,05) con todas las variables antropométricas analizadas, y una mayor fuerza de correlación con la CC y el IMC. El punto de corte de la CN seleccionado como predictor de riesgo de complicaciones metabólicas cardiacas y obesidad troncular en mujeres fue ≥ 32,4 cm, considerando tanto la CC como el IMC. En el caso de los hombres, los puntos de corte de la CN fueron diferentes al considerar como referencia la CC (≥ 39,6 cm) y el IMC (≥ 38,1 cm). Cabe destacar que la CN obtuvo buenos resultados en el análisis de la curva ROC en el caso de los hombres, mientras que en el de las mujeres fue deficiente. Conclusión: la CN demostró ser un indicador prometedor en la evaluación de la nutrición y la salud de las personas que viven con el VIH, especialmente en los hombres.

Objectives: To summarize evidence-based cognitive-behavioral therapy (CBT) treatment and propose clinical interventions for adult patients with obsessive-compulsive disorder (OCD). Methods: The literature on CBT interventions for adult OCD, including BT and exposure and response prevention, was systematically reviewed to develop updated clinical guidelines for clinicians, providing comprehensive details about the necessary procedures for the CBT protocol. We searched the literature from 2013-2020 in five databases (PubMed, Cochrane, Embase, PsycINFO, and Lilacs) regarding study design, primary outcome measures, publication type, and language. Selected articles were assessed for quality with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association. Results: We examined 44 new studies used to update the 2013 American Psychiatric Association guidelines. High-quality evidence supports CBT with exposure and response prevention techniques as a first-line treatment for OCD. Protocols for Internet-delivered CBT have also proven efficacious for adults with OCD. Conclusion: High-quality scientific evidence supports the use of CBT with exposure and response prevention to treat adults with OCD.

Objectives: To summarize evidence-based pharmacological treatments and provide guidance on clinical interventions for adult patients with obsessive-compulsive disorder (OCD). Methods: The American Psychiatric Association (APA) guidelines for the treatment of OCD (2013) were updated with a systematic review assessing the efficacy of pharmacological treatments for adult OCD, comprising monotherapy with selective serotonin reuptake inhibitors (SSRIs), clomipramine, serotonin and norepinephrine reuptake inhibitors (SNRIs), and augmentation strategies with clomipramine, antipsychotics, and glutamate-modulating agents. We searched for the literature published from 2013-2020 in five databases, considering the design of the study, primary outcome measures, types of publication, and language. Selected articles had their quality assessed with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association (ACC/AHA). Results: We examined 57 new studies to update the 2013 APA guidelines. High-quality evidence supports SSRIs for first-line pharmacological treatment of OCD. Moreover, augmentation of SSRIs with antipsychotics (risperidone, aripiprazole) is the most evidence-based pharmacological intervention for SSRI-resistant OCD. Conclusion: SSRIs, in the highest recommended or tolerable doses for 8-12 weeks, remain the first-line treatment for adult OCD. Optimal augmentation strategies for SSRI-resistant OCD include low doses of risperidone or aripiprazole. Pharmacological treatments considered ineffective or potentially harmful, such as monotherapy with antipsychotics or augmentation with ketamine, lamotrigine, or N-acetylcysteine, have also been detailed.

Resumo: O artigo caracterizou a adoção do Manejo Integrado de Pragas (MIP) na produção paulista de laranja a partir do LUPA 2016/2017. Para tanto, buscou apoio nas construções teóricas e conceituais sobre mudança tecnológica e MIP, para conduzir análise pautada no cenário de produção, comercialização, organizacional e de P&D da cultura da laranja, assim como do tratamento e análise de informações censitárias, LUPA 2016/2017, no recorte do MIP e da produção de laranja. Os resultados apontam o forte posicionamento internacional do suco de laranja brasileiro e paulista, associado a uma ampla e consolidada estrutura de representação da agroindústria e da produção agrícola, bem como das atividades públicas e privadas de P&D. Esses resultados convivem com a limitada oferta de tecnologias para solução dos principais problemas fitossanitários da cultura. Nesse ambiente, o MIP toma espaço como alternativa viável e importante, estando presente em 40% da área e pés em produção, em propriedades em que a laranja é a principal fonte de renda familiar, com proprietários que possuem maior nível educacional e são cooperados ou associados. O MIP também foi relacionado a outras tecnologias, a exemplo do uso de mudas certificadas e do crédito e seguro rural.

Abstract: The article characterized the adoption of Integrated Pest Management (IPM) in orange production in São Paulo from LUPA 2016/2017. To this end, it sought support in theoretical and conceptual constructions on technological change and MIP, to conduct an analysis based on the production, commercialization, organizational and R&D scenario of the orange crop, as well as the treatment and analysis of census information, LUPA 2016/ 2017, in the cut of MIP and orange production. The results point to the strong international positioning of Brazilian and São Paulo orange juice, associated with a broad and consolidated structure of representation of agro-industry and agricultural production, as well as public and private R&D activities. These results coexist with the limited supply of technologies to solve the main phytosanitary problems of the crop. In this environment, MIP takes place as a viable and important alternative, being present in 40% of the area and plants in production, in properties where orange is the main source of family income, with owners who have a higher educational level and are cooperative or associated. . The MIP was also related to other technologies, such as the use of certified seedlings and rural credit and insurance.

Resumen Objetivo: evaluar los efectos de un suplemento especializado en el control de la glucosa (GTSS) frente a un desayuno estándar sobre la glucemia posprandial (PPG). Metodología: es un estudio cruzado, prospectivo, aleatorizado en el que se incluyeron a pacientes con diabetes tipo 2 (T2D) con control subóptimo de la glucemia (HbA1c entre 6,5 y 8,5 %) utilizando monoterapia con metformina. El desayuno estandarizado fue isocalórico en comparación con el GTSS y solamente la distribución calórica fue diferente. Ambas intervenciones se utilizaron una vez al día por la mañana, reemplazando cada una el desayuno durante 7 días consecutivos (14 días de observación). Se utilizó el sistema de monitoreo continuo de glucosa (isCGM) para determinar las diferencias entre las intervenciones con respecto al área bajo la curva (iAUC) de glucosa postprandial (PPG) (3 horas después de la intervención) como variable principal o primaria; las variables secundarias fueron la diferencia entre las intervenciones con respecto al pico glicémico, la excursión de glucosa posprandial (PPGE), la glucosa media en sangre (MBG) y el rango de tiempo (TIR). Resultado: se incluyeron treinta y un pacientes con T2D con edades entre 39 y 69 años. El grupo del GTSS tuvo un área bajo la curva (iAUC) significativamente más baja de la PPG en comparación con el grupo del desayuno estandarizado (33,3 [15,0 a 54,0] frente a 46,8 [27,3 a 75,1] mg/dL), mientras que también presentó una PPG significativamente más baja (26,4 + 17,2 vs. 44,8 + 24,4 mg/dL). No hubo diferencia entre los períodos de intervención con respecto a la MBG, el TIR y eventos hipoglucémicos. Conclusión: el nuevo GTSS, como sustituto del desayuno, produjo una reducción de la iAUC de la PPG del 25 %, según el isCGM, en comparación con un desayuno isocalórico normalizado.

Abstract Objective: to evaluate the effects of a new glycemia targeted specialized supplement (GTSS) compared to a standard breakfast on postprandial blood glucose (PPG). Methods: patients with type 2 diabetes (T2D) and suboptimal control (A1C between 6.5 and 8.5 %) in monotherapy with metformin were included to this prospective, randomized, crossover trial. The standardized breakfast was isoenergetic compared to the GTSS, differing on macronutrients distribution. Both interventions were used once a day in the morning, each replacing breakfast for 7 consecutive days (14 days of observation). Intermittent scanning continuous glucose monitoring system (isCGM) determined the difference between the interventions regarding the incremental area under the curve (iAUC) of the PPG (3 hours after intervention), as a primary endpoint; secondary endpoints were the difference between the interventions regarding the glycemic peak, postprandial glucose excursion (PPGE), mean blood glucose (MBG) and time in range (TIR). Results: thirty-one T2D patients with ages between 39 and 69 years-old were enrolled. GTSS group had significantly lower iAUC of the PPG compared to standardized breakfast (33.3 [15.0 to 54.0] vs 46.8 [27.3 to 75.1] mg/dL), while also presenting a significantly lower PPG excursion (26.4 ± 17.2 vs 44.8 ± 24.4 mg/dL). There was no difference between the intervention periods regarding MBG, TIR and hypoglycemic events. Conclusion: the new GTSS, as a meal replacement in the breakfast, produced a 25 % reduction in the iAUC of the PPG, as accessed by isCGM, in comparison with an isocaloric-standardized meal.

Abstract Objective: The aim of our study was to evaluate the expression of MMP-2 and MMP-9 as a prognostic factor in patients diagnosed with Hodgkin Lymphoma (HL). Methods: In the present study, 45 paraffin biopsies from patients up to 19 years old diagnosed with HL were used in two referral hospitals in the state of Pernambuco, Brazil. Risk groups were classified into favorable and unfavorable, according to Ann Arbor. The expression of matrix metalloproteinases 2 and 9 and their inhibitors was performed by immunohistochemistry (IHC). Data were analyzed using the GraphPad Prism 5 program. Results: MMP-2 intensity pattern was stronger (> 10% of the total field) in patients with stage III/ IV and B symptoms. MMP-2 showed an association with the risk group (p = 0.0388). That is, the stronger the MMP-2 marking, the greater the unfavorable risk. However, for MMP-9 there was no difference in the stronger intensity pattern in relation to stages I/II and III/IV, only in the presence of B symptoms. MMP-9 showed an association with B Symptoms (p = 0.0411). Therefore, patients with B symptoms have higher MMP-9 expression. Conclusion: Our results suggest that MMP-2 expression is associated with HL progression. While MMP-9 expression is related to the clinical worsening of these patients. However, further studies are needed to evaluate the exact role of these proteins in hematologic malignancies.

Resultados. La región de América Latina y el Caribe definida por el estudio de la CME ocupó el primer lugar a nivel mundial en mortalidad y AVAD de motociclistas varones de 15 a 49 años en el 2019. Las tasas tuvieron un notable aumento del 2010 al 2013, y ambas registraron una reducción importante después de ese período. En la década analizada, la subregión de América Latina Tropical (Brasil y Paraguay) presentó las mayores tasas de mortalidad y de AVAD en la población de estudio, pero fue la única con una reducción importante de las mismas. La subregión del Caribe (Antigua y Barbuda, Bahamas, Barbados, Belice, Bermudas, Cuba, Dominica, Granada, Guyana, Haití, Islas Vírgenes de Estados Unidos, Jamaica, Puerto Rico, República Dominicana, Saint Kits y Nevis, San Vicente y las Granadinas, Santa Lucía, Suriname, y Trinidad y Tabago) mostró un aumento importante de ambas tasas, mientras que América Latina Andina (Bolivia, Ecuador y Perú) y América Latina Central (Colombia, Costa Rica, El Salvador, Guatemala, Honduras, México, Nicaragua, Panamá y Venezuela) se mantuvieron estables. Conclusiones. Los datos refuerzan la importancia de las actividades de vigilancia destinadas a prevenir los accidentes de motocicleta, puesto que la reducción observada de las tasas aún es insuficiente para abordar la morbimortalidad por accidentes de tráfico como problema de salud pública.

ABSTRACT Objective. To identify the temporal trend in mortality and years of life lost to death or disability (DALY) due to motorcycle accidents in males from Latin America and the Caribbean from 2010 to 2019, using estimates produced by the Global Burden of Disease (GBD) study. Method. In this ecological study, the time series was analyzed using a piecewise linear regression model (joinpoint) to estimate and test the annual percent change and the average annual percent change with a 95% confidence interval. Results. The super-region defined by GBD 2019 as Latin America and the Caribbean ranked first globally in mortality and DALY for male motorcyclists aged 15-49 in 2019. Rates increased significantly from 2010 to 2013, with a significant reduction in both after this period. During the analyzed decade, the Tropical Latin America sub-region (Brazil and Paraguay) had the highest mortality and DALY rates in the population of interest; nevertheless, this was the only sub-region achieving a significant reduction in these rates. The Caribbean sub-region (Bermuda, Dominica, Suriname, Guyana, Belize, Bahamas, Puerto Rico, Saint Lucia, Dominican Republic, Haiti, Saint Kitts and Nevis, U.S. Virgin Islands, Grenada, Trinidad and Tobago, Barbados, Saint Vincent and the Grenadines, Antigua and Barbuda, Cuba e Jamaica) showed a significant increase in both rates over the same period, while Andean Latin America (Ecuador, Bolivia and Peru) and Central Latin America (Colombia, Costa Rica, El Salvador, Guatemala, Mexico, Nicaragua, Panama, Honduras, and Venezuela) remained stable. Conclusions. The data underscore the importance of developing surveillance actions aimed at preventing motorcycle accidents, since the observed declining rates are still insufficient to address the morbidity and mortality associated with road accidents as a public health problem.

RESUMO Objetivo. Identificar a tendência temporal da mortalidade e dos anos de vida perdidos por morte ou incapacidade (DALY) de homens por acidente motociclístico na América Latina e Caribe no período de 2010 a 2019, utilizando estimativas do estudo Global Burden of Disease (GBD). Métodos. Este estudo ecológico analisou a série temporal pelo modelo de regressão linear segmentada (joinpoint), estimando-se e testando-se a variação percentual anual e a variação percentual anual média, com intervalo de confiança de 95%. Resultados. A grande região da América Latina e Caribe definida pelo GBD ocupou o primeiro lugar global em mortalidade e DALY de motociclistas homens de 15 a 49 anos em 2019. As taxas aumentaram significativamente de 2010 a 2013, havendo redução significativa de ambas após esse período. Durante a década analisada, a sub-região da América Latina Tropical (Brasil e Paraguai) apresentou as maiores taxas de mortalidade e DALY na população em estudo, porém foi a única com redução significativa das mesmas; a sub-região do Caribe (Bermudas, Dominica, Suriname, Guiana, Belize, Bahamas, Porto Rico, Santa Lúcia, República Dominicana, Haiti, São Cristóvão e Névis, Ilhas Virgens/EUA, Granada, Trinidad e Tobago, Barbados, São Vicente e Granadinas, Antígua e Barbuda, Cuba e Jamaica) apresentou aumento significativo de ambas as taxas, enquanto América Latina Andina (Equador, Bolívia e Peru) e América Latina Central (Colômbia, Costa Rica, El Salvador, Guatemala, México, Nicarágua, Panamá, Honduras e Venezuela) permaneceram estáveis. Conclusões. Os dados reforçam a importância das ações de vigilância destinadas à prevenção de acidentes motociclísticos, uma vez que os resultados de queda nas taxas ainda são insuficientes frente à morbimortalidade no trânsito como problema de saúde pública.

RESUMO OBJETIVO Identificar as normas jurídicas publicadas nos anos de 2020 e 2021 para regular direta ou indiretamente o teletrabalho em saúde no Brasil, analisando-as sob o enfoque dos seguintes temas, no contexto do teletrabalho: tempo da jornada de trabalho; ergonomia; ambiente laboral; segurança e saúde do trabalhador. MÉTODOS Pesquisa legislativa e documental, com abordagem qualitativa descritiva. Foram coletadas e selecionadas todas as normas jurídicas que tratam direta ou indiretamente da regulação do teletrabalho em saúde no Brasil, publicadas nas bases da Imprensa Nacional e dos Conselhos Profissionais da área da saúde até junho de 2021. RESULTADOS Destacam-se os seguintes: até junho de 2021 havia 113 normas jurídicas vigentes sobre a regulação do teletrabalho em saúde, sendo mais da metade (64) publicadas no ano de 2020. Dentre os achados, identificou-se um baixo número de normas voltadas a regular ou orientar aspectos relacionados ao tempo da jornada de trabalho; à ergonomia; ao ambiente laboral; à segurança e à saúde do trabalhador. Do total das 113 normas, apenas uma trata da jornada de trabalho e somente 13 destacaram a importância de que os ambientes de trabalho tenham condições para o oferecimento de um bom serviço. DISCUSSÃO Identificamos ausências, nas normas jurídicas selecionadas, de dispositivos que regulam o teletrabalho em saúde, a fim de prover a defesa dos direitos do trabalhador e dos pacientes, ou ainda para garantir condições favoráveis à realização do teletrabalho, seja realizado nos domicílios, seja em outro espaço.

ABSTRACT OBJECTIVE To identify the legal norms published in 2020 and 2021 aimed at directly or indirectly regulating telework in health in Brazil, focusing on these contexts: workday length; ergonomics; work environment; worker safety and health. METHODS Legislative and documentary research, with a descriptive qualitative approach. We collected and selected all legal norms dealing directly or indirectly with the regulation of telework in health in Brazil, published in the bases of the National Press and Health Professional Councils until June 2021. RESULTS Until June 2021, there were 113 valid legal norms on the regulation of telework in health, and more than half of them (64) were published in 2020. We identified only a few norms aimed at regulating or guiding aspects related to workday length; ergonomics; work environment; and worker safety and health. From the 113 norms, only one deals with workday length and just 13 pointed out the importance of working environments for offering a good service. DISCUSSION We identified that the selected legal norms lack of devices which regulate telework in health, failing to defend workers’ and patients’ rights, or to guarantee favorable remote work conditions, whether at home or somewhere else.
