Multiple-target Therapy for Posttransplant Focal Segmental Glomerulosclerosis.

Background: There is no consensus on the ideal strategy to treat posttransplant focal segmental glomerulosclerosis. The multiple-target therapy, which consisted of high-dose intravenous cyclosporine, prednisone, and plasmapheresis, showed favorable results. Methods: This single-center, prospective study sought to evaluate the multiple-target therapy in an independent cohort of patients. Results: Thirteen patients with posttransplant focal segmental glomerulosclerosis received multiple-target therapy. Complete remission was achieved in 2 patients (15.4%), and partial remission in another 2 patients (15.4%). Four patients (30.7%) did not show remission, and 5 patients (38%) lost the graft because of posttransplant focal segmental glomerulosclerosis during the 12-mo follow-up. Premature discontinuation of treatment occurred in 10 patients (77%), all associated with infectious adverse events. Cytomegalovirus was the most common complication, and preemptive therapy was used instead of prophylaxis. Conclusions: In this cohort of patients, the efficacy of the multiple-target therapy was poor and limited by the high incidence of infectious adverse events.

Dissimilar forests along the Rio Doce watershed call for multiple restoration references to avoid biotic homogenization.

An environmental disaster caused by the rupture of a mining tailings dam has impacted a large area of the Rio Doce watershed in the Brazilian Atlantic Forest, resulting in unprecedented damage at spatial and temporal scales. The Atlantic Forest is one of the world's most important biodiversity hotspots. A long history of land use conversion has resulted in a highly fragmented landscape. Despite numerous restoration initiatives, these efforts have often biased criteria and use limited species assemblages. We conducted a comprehensive synthesis of the plant community in riparian forests along the Rio Doce watershed. Our work detailed vegetation composition (tree and sapling strata) and examined its relationship with edaphic and landscape factors, aiming to inform restoration projects with scientifically robust knowledge. A total of 4906 individuals from the tree strata and 4565 individuals from the sapling strata were recorded, representing a total of 1192 species from 75 families. Only 0.8% of the tree species and 0.5% of the sapling species occurred in all sampled sectors, with over 84% of the species occurring in a single watershed sector for both strata. We observed a high species heterogeneity modulated by turnover (92.3% in the tree, and 92.7% in the sapling strata) among sites. Overall, our research revealed a gradient of soil fertility influencing species composition across different strata. Additionally, we discovered that preserved landscapes had a positive impact on species diversity within both strata. The species exclusivity in the sampled sites and the high turnover rate imply the need to consider multiple reference ecosystems when restoring the watershed to reduce the risk of biotic homogenization. Finally, the reference ecosystems defined here serve as a basis for the selection of locally particular species in the implementation of restoration projects that aim to improve biodiversity, ecosystem services, and water security.

Application of starch-rich mango by-product as filler for the development of an additive manufacturing filament compound.

The surge in global polymeric waste underscores the imperative for biodegradable materials to substitute traditional polymers. Crucially, advancements are needed for emerging technologies like Materials Extrusion (ME) in additive manufacturing, where current biodegradable materials exhibit limitations. This work was based on the development of a biodegradable composite filament. The inner of the mango seed (kernel) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) were used as raw materials. The properties of PHBV and mango by-product mixture were first evaluated by direct-extrusion printing. Then, the feasibility of manufacturing the filaments was studied. Initially, the kernel seed mango was characterized thermally, chemically, and morphologically by DSC, FTIR, and SEM, respectively. It was observed that the addition of mango by-product contributed to the decrease of PHBV crystallinity, resulting in the reduction of printed parts retraction and increases the Tg, as shown by the DMA. The structure of the native starch was preserved due to non-gelatinization, even after processing steps, as indicated by thermal, chemical, and morphological analyses. Finally, PHBV filaments containing mango by-products were fabricated, and prototypes were manufactured by ME to demonstrate the potential for market acceptance and commercialization of the studied filament.

Impact of different kernel grades on volatile compounds profile, fatty acids and oxidative quality of cashew nut oil.

In this study, the impact of kernel grade on the physicochemical quality, fatty acids, and volatile compounds of cashew nut oil was assessed. The oil samples were obtained from different classifications of nuts and analyzed for acid and peroxide values, color, fatty acids and volatile compounds. The broken kernel oils showed similar or superior quality to the whole kernel oil (LW3), especially samples B3 (batoque) and P3 (large piece), with acid, peroxide and color values equal to the one in LW3. The oils from less intact nuts showed high proportions of monounsaturated fatty acids (MUFA), with acid ratios higher than the ones in LW3 (64.47 to 65.28 %, while the latter displayed 63.33 %). Sample P3 showed higher proportions of volatile compounds not derived from oxidation. This study expands the possibility of valorizing lower commercial value cashew nuts by producing oil with adequate quality for consumption.

Lipid nanoparticles based on natural matrices with activity against multidrug resistant bacterial species.

Lately, the bacterial multidrug resistance has been a reason to public health concerning around world. The development of new pharmacology therapies against infections caused by multidrug-resistant bacteria is urgent. In this work, we developed 10 NLC formulations composed of essential oils (EO), vegetable butter and surfactant. The formulations were evaluated for long-term and thermal cycling stability studies in terms of (particle size, polydispersion index and Zeta potential). In vitro antimicrobial assays were performed using disk diffusion test and by the determination of the minimum inhibitory concentration (MIC) performed with fresh and a year-old NLC. The most promising system and its excipients were structurally characterized through experimental methodologies (FTIR-ATR, DSC and FE-SEM). Finally, this same formulation was studied through nanotoxicity assays on the chicken embryo model, analyzing different parameters, as viability and weight changes of embryos and annexes. All the developed formulations presented long-term physicochemical and thermal stability. The formulation based on cinnamon EO presented in vitro activity against strains of Acinetobacter baumannii, Klebsiella pneumoniae and Pseudomonas aeruginosa isolated from humans and in vivo biocompatibility. Considering these promising results, such system is able to be further tested on in vivo efficacy assays.

Olfactory and gustatory disorders caused by COVID-19: How to regain the pleasure of eating?

BACKGROUND: Recently, anosmia and ageusia (and their variations) have been reported as frequent symptoms of COVID-19. Olfactory and gustatory stimuli are essential in the perception and pleasure of eating. Disorders in sensory perception may influence appetite and the intake of necessary nutrients when recovering from COVID-19. In this short commentary, taste and smell disorders were reported and correlated for the first time with food science. SCOPE AND APPROACH: The objective of this short commentary is to report that taste and smell disorders resulted from COVID-19 may impact eating pleasure and nutrition. It also points out important technologies and trends that can be considered and improved in future studies. KEY FINDINGS AND CONCLUSIONS: Firmer food textures can stimulate the trigeminal nerve, and more vibrant colors are able to increase the modulation of brain metabolism, stimulating pleasure. Allied to this, encapsulation technology enables the production of new food formulations, producing agonist and antagonist agents to trigger or block specific sensations. Therefore, opportunities and innovations in the food industry are wide and multidisciplinary discussions are needed.

PERCEPTION, DEGRADATION AND ENVIRONMENTAL EDUCATION OF RIBEIRINHOS FROM IGARAÇU RIVER, PIAUÍ, BRAZIL / PERCEPCIÓN, DEGRADACIÓN Y EDUCACIÓN AMBIENTAL DE RIBEIRINHOS DE RIO IGARAÇU, PIAUÍ, BRASIL / PERCEPÇÃO, DEGRADAÇÃO E EDUCAÇÃO AMBIENTAL DE RIBEIRINHOS DO RIO IGARAÇU, PIAUÍ, BRASIL

Investigations approaching environmental perception clarify fundamental thoughts and attitudes for the development of assimilative environmental education. This study aimed to understand the environmental perception of riverside dwellers in the Igaraçu River, Parnaíba, Piauí, regarding the environmental damage that occurs in the river. One person responsible for each riverine family was selected. These were interviewed using semi-structured forms and asked about the environmental damage that occurs in the river, its causes and consequences. Results were evaluated by Loyalty Level (FL). Most of them perceive the existence of damage in the river (67.86%, n:38). Among the damages, the main causes are garbage (FL: 74.41) and sewage (FL: 11, 60). Although the community depends on the river for food and hydration, most of them do not feel prejudiced (56.9%). On the other hand, they perceive that fauna (FL: 55.35%) and flora (FL: 35.70) are being negatively affected. It is concluded that the informants are aware of the damage that occurs in the river, its causes and consequences, but they do not realize how these changes affect their lives. Thus, it is necessary to incorporate these data in the construction of the environmental education process in this community so that it is more assimilative and effective, to build changes in attitudes, values and mitigation of damage to health.

Investigaciones que abordan el percepción ambiental aclaran pensamientos y actitudes fundamentales para la elaboración de una educación ambiental asimilativa. El objetivo fue comprender la percepción ambiental de los habitantes de las riberas del río Igaraçu, Parnaíba, Piauí, sobre el daño ambiental que se produce en el río. Se seleccionó a una persona responsable de cada familia ribereña. Estos fueron entrevistados a través de formularios semiestructurados y se les preguntó sobre el daño ambiental que se produce en el río, sus causas y consecuencias. Los resultados fueron evaluados por nivel de lealtad (FL). La mayoría percibe la existencia de daños en el río (67,86%, n: 38). Entre los daños, las principales causas son basura (FL: 74.41) y eliminación de agua contaminada (FL: 11, 60). A pesar de la comunidad depende del río para su alimentación e hidratación, gran parte no se siente perjudicada (56,9%), por otro lado perciben que la fauna (FL: 55,35%) y la flora (FL: 35,70) están siendo afectadas. Se concluye que los informantes son conscientes del daño que se produce en el río, sus causas y consecuencias, pero no se dan cuenta de cómo esto afecta sus vidas. Por ello, es necesario incorporar estos datos en la construcción del proceso de Educación Ambiental de esta comunidad para que sea más asimilable y eficaz a fin de construir cambios de actitudes, valores y mitigación de daños a la salud.

Rapid displacement of SARS-CoV-2 variant B.1.1.7 by B.1.617.2 and P.1 in the United States

This study reports on the displacement of Alpha (B.1.1.7) by Delta (B.1.617.2 and its substrains AY.1, AY.2, and AY.3) in the United States. By analyzing RT-qPCR testing results and viral sequencing results of samples collected across the United States, we show that the percentage of SARS-CoV-2 positive cases caused by Alpha dropped from 67% in May 2021 to less than 3.0% in just 10 weeks. We also show that the Delta variant has outcompeted the Iota (B.1.526) variant of interest and Gamma (P.1) variant of concern. An analysis of the mean quantification cycles (Cq) values in positive tests over time also reveal that Delta infections lead to a higher viral load on average compared to Alpha infections, but this increase is only 2 to 3x on average for our study design. Our results are consistent with the hypothesis that the Delta variant is more transmissible than the Alpha variant, and that this could be due to the Delta variants ability to establish a higher viral load earlier in the infection compared to the Alpha variant.

Vascular plant checklist in an area of extreme biological importance: filling gaps in the Caparaó National Park-ES, Brazil / Checklist de plantas vasculares em uma área de extrema importância biológica: preenchendo lacunas no Parque Nacional do Caparaó-ES, Brasil

Abstract Regional floristic lists are essential for defining biodiversity conservation strategies and are key to assist in filling knowledge gaps. They aim to provide a data source for applying tools to reduce extinction rates and to conserve ecosystems. Herein we present the results of an inventory of vascular plants in a rainforest in the Caparaó National Park (CNP) and approach their implications for conservation and management of this protected area and the surrounding communities. We conducted botanical expeditions between the years 2012 and 2017 in a montane and upper-montane forest of the CNP. We found 361 species distributed in 78 families and 181 genera. The study area is home to new species for science that have recently been described in other publications outside that location, and 4 new records for Espírito Santo State; also 43 species listed in different extinction threat categories (VU, EN and CR) and another 190 categorized with lesser concerns (LC and NT). The families with the highest species richness were: Melastomataceae (41 spp.), Lauraceae and Myrtaceae (30), Orchidaceae (26), Rubiaceae (24), and Asteraceae (20). Our results contribute to greater knowledge of the CNP flora, of the montane environments in Brazil and the vegetation of Espírito Santo state, in addition to demonstrate the importance of this protected area to the conservation Atlantic Forest biodiversity.

Vascular plants on inselberg landscapes in Espírito Santo state: bases for the creation of a protected area in southeastern Brazil

Inselbergs are granitic or gneissic rocky outcrops prevalent in the landscape of southeastern Brazil. These ecosystems represent islands of isolated habitats that harbor a peculiar flora with high richness and endemism. The present study lists the species of vascular plants occurring in the Pedra da Andorinha Complex, located in the municipality of Jerônimo Monteiro/Cachoeiro de Itapemirim, southern Espírito Santo state, aiming to generate subsidies for the creation of a protected area. The survey was performed between July 2017 and October 2018, resulting in a record of 121 species, 96 genera, and 40 families. Bromeliaceae (17), Orchidaceae (12) and Fabaceae (10) were the richest families. The phytophysiognomy of exposed rock vegetation comprises a greater number of species (79 species) compared to the woody rupicolous communities (42). Eighteen of the collected species are threatened by extinction; a new species was discovered; and five were described based on materials previously collected in the studied location — Alcantarea patriae, Anthurium martinellii, Coleocephalocereus uebelmanniorum, Stigmatodon attenuatoides and Pitcairnia azouryi, the first four being endemic to the region. We also found Tabebuia reticulata, a rare species among Brazilian flora. Our results highlight the biological importance of the Pedra das Andorinhas Complex and reinforce the need to create a protected area to preserve biodiversity and the regional natural heritage.

Evaluation of cooking methods on the bioactive compounds of cashew apple fibre and its application in plant-based foods.

Plant co-products currently represent an attractive alternative to the food industry, especially to the growing market of development low-fat products. Among the co-products resulting from tropical fruits' processing, the cashew apple's fibre presents unusual nutritional and sensory characteristics. In several food preparations could use it as an ingredient. In this work, the bioactive compounds of both artisanal and industrialized cashew apple fibre were studied and the influence of the different cooking methods on their bioactive content, and the acceptance and sensory preference of products new plants-based products formulated. It was observed that both artisanal and industrial cashew apple fibres presented a rich composition in the bioactive compounds, especially regarding the content of ascorbic acid found in artisanal (147.8 mg.100g-1) and carotenoids in industrialized fibre (1.87 mg 100 g-1), which resulted in a higher antioxidant activity for both samples in each method evaluated. Frying (180 °C/3 min) and cooking in a combination oven (98 °C/10 min) exhibited higher averages regarding the retention of the bioactive compounds in the fibres, resulting in a higher antioxidant activity for the products processed by these methods. In contrast, it was boiling processing (100 °C/18min) leads to leach of water-soluble biocompounds and, consequently, their products presented a reduced antioxidant activity. The cashew apple "paçoca" and "meatballs" were judged in terms of their attributes (appearance, aroma, taste, overall impression) and buy intention. In general, the average of these results indicated a high sensorial acceptance and a partial possibility in their purchase of these products. The cashew apple fibres are a source of nutrients. Its incorporation in culinary preparations can be a friendly way to avoid waste and promote new food products.

Determination of water-soluble vitamins and carotenoids in Brazilian tropical fruits by High Performance Liquid Chromatography.

Vitamins are organic compounds essential for normal physiological functioning and they need to be provided in adequate amounts by the diet. They are nutrients mainly associated to fruit consumption, playing an important role in the cellular function, growth and development of individuals. The present study aimed to analyze levels of vitamins B, C and carotenoids of fruits from the agrobiodiversity of Northeastern Brazil, among them cajuí (Anacardium spp), murici (Byrsonima crassifolia (L.) Kunth), pequi (Caryocar coriaceum Wittm.), jenipapo (Genipa americana L.), mangaba (Hancornia speciosa Gomes), bacuri (Platonia insignis Mart.), cajá (Spondias mombin L.), umbu-cajá (Spondias bahiensis P. Carvalho, Van den Berg & M. Machado), umbu (Spondias tuberosa Arruda), pitanga (Eugenia uniflora L.), araçá (Psidium sobralianum Landrum & Proença). The vitamins were quantified using the analytical method High Performance Liquid Chromatography (HPLC). Vitamin B complex levels varied from 0.003 ± 0.01 mg/100 g to 6.107 ± 0.06 mg/100 g. Vitamin C ranged from 0.36 ± 0.06 mg/100 g to 253.92 ± 9.02 mg/100 g. Carotenoid values ranged from 0.12 ± 0.02 µg/100 g to 395.63 ± 113.69 µg/100 g. Thus, the profile of water-soluble vitamins and carotenoids of the fruits analyzed was quantified. Therefore, these fruits can provide varied amounts of vitamins important to human health. However, it is interesting for the individual to consume fruits in a diversified manner, avoiding monotony and thus guaranteeing the daily intake of more nutrients.

Complex coacervates of cashew gum and gelatin as carriers of green coffee oil: The effect of microcapsule application on the rheological and sensorial quality of a fruit juice.

In this work, cashew gum (CG) and gelatin (GE) complexation was explored to encapsulate green coffee oil (GCO), rich in cafestol and kahweol, for use as ingredient in fruit juice. The microcapsules were loaded with 25, 50 and 75% (w/w) GCO and characterized by scanning electron microscopy, encapsulation efficiency and accelerated oxidation by Rancimat. Gas chromatography coupled to the mass detector was used to cafestol quantification in simulated gastrointestinal digestion and during fruit juice storage. Particles with 25% GCO (14.56 ± 6.36 µm) presented good encapsulation efficiency (85.57 ± 1.41%), reduced the GCO oxidation by six-fold and were resisted in the pasteurization conditions. The beverage added of capsules showed good sensory quality when compared to the control formulation. For the first time, the incorporation of GCO capsules into fruit juice has been reported, promoting a diterpene-rich drink with good rheological and sensory properties.

Garlic passion fruit (Passiflora tenuifila Killip): Assessment of eventual acute toxicity, anxiolytic, sedative, and anticonvulsant effects using in vivo assays.

Several Passiflora species are known for their sedative and anxiolytic properties. However, the functional properties of Passiflora tenuifila Killip are still unexplored. The objective of this work was to evaluate the phenolic composition and acute toxicity, anxiolytic, sedative, and anticonvulsant effects using in vivo assays. The whole fruit (peel, pulp, and seed) was lyophilized and used for all assays. LC-MS showed 19 phenolic compounds, tentatively identified as flavonoids and phenolic acids. Acute treatment with single doses of up to 2000 mg kg-1 in Wistar rats showed no signs of mortality or toxicity over 14 days. The assay of functional effects was performed with Swiss mice, four groups, received by gavage, doses of P. tenuifila (200 or 400 mg kg-1 body weight), water, and diazepam (as negative and positive control), and behavior tests were performed after 60 min of the treatments. The animals treated with P. tenuifila fruit showed a significant decrease in locomotor activity, indicating a sedative and anxiolytic activity. No significant changes were observed in the rotarod apparatus, suggesting that the P. tenuifila fruit did not cause muscle relaxation. The 400 mg kg-1 dose of P. tenuifila exerted a protective effect against pentylenetetrazole-induced seizures, decreasing the severity and not causing the death of the animals. In conclusion, P. tenuifila showed no acute toxicity and had a promising effect as an anxiolytic agent, hypnotic-sedative and anticonvulsant, which could be related to its composition of flavonoids and phenolic acids.

Clinical and pathological features of thrombotic microangiopathy influencing long-term kidney transplant outcomes.

INTRODUCTION: Thrombotic microangiopathy (TMA) in post-transplant setting has heterogeneous clinical manifestations. METHODS: We retrospectively studied data of 89 patients with post-transplant TMA, which was characterized by thrombi in at least one glomerulus and/or arteriole. Systemic TMA was defined by thrombocytopenia and microangiopathic anemia and early onset TMA, when occurred less than 90 days post transplant. RESULTS: The cumulative incidence was 0.93%. The majority of the recipients were young (mean age 39 years), female (52%) and Caucasian (48%) with primary kidney disease of unknown etiology (37%). Early TMA occurred in 51% of the patients and systemic TMA, in 25%. Underlying precipitating factors were: infection (54%), acute rejection (34%), calcineurin inhibitor toxicity (13%) and pregnancy (3%). 18% of the patients had several triggers. Glomerular TMA was observed in 50% of the biopsies and endothelial cell activation, in 61%. The 1-year patient survival was 97% and corresponding graft survival, 66%. Allograft survival was inferior when acute antibody mediated rejection (ABMR) occurred (with 41%; without 70%, p = 0.01), however no differences were determined by hemolysis, time of onset, thrombi location or endothelial cell activation. CONCLUSIONS: Our results suggest that post-transplant TMA is a rare but severe condition, regardless of its clinical and histological presentation, mainly when associated to ABMR.

Graviola Fruit Bar Added Acerola By-Product Extract Protects Against Inflammation and Nociception in Adult Zebrafish (Danio rerio).

Studies involving foods associated with pain reversal and anti-inflammatory effects using zebrafish are rarely reported in the literature. This study aimed to evaluate the effect of graviola (Annona muricata L.) fruit bar (GFB) and GFB added with acerola (Malpighia glabra L) seed extract (ASE) on acute nociception and abdominal inflammation in adult zebrafish (Danio rerio). Acute nociception was induced by formalin, capsaicin, cinnamaldehyde, acidic saline, glutamate (cutaneous models), and hypertonic saline (corneal model), and inflammation was induced by carrageenan. Both GFB and ASE exhibited antinociceptive effect modulated by the nitrergic system, guanylate cyclase, and transient receptor potential ankyrin 1 and acid-sensing ion channels. The antinociceptive effect of GFB also appears to be modulated by the opioid system and glutamatergic receptors (N-methyl-D-aspartate receptor). Only ASE presented corneal antinociceptive effect. Both samples showed anti-inflammatory effect, being more significant the effect of GFB. The addition of acerola by-product extract in GFB results in a product with greater biological potential.

Introdução: O câncer de mama é considerado um problema de saúde pública, tendo crescente incidência mundial. Diversos fatores contribuem para o diagnóstico tardio e dificultam o início do tratamento, repercutindo em um pior prognóstico. Objetivos: Analisar o intervalo de tempo entre o diagnóstico e o início do primeiro tratamento oncológico na população brasileira, além de avaliar os fatores associados aos maiores intervalos. Método: Trata-se de um estudo de coorte retrospectivo com 540.529 pacientes cadastrados no Sistema de Registros Hospitalares de Câncer (SisRHC)no período de 2000 a 2017. Utilizou-se como desfecho o intervalo de tempo entre o diagnóstico e o início do primeiro tratamento oncológico, considerando-se como atraso o intervalo maior do que 60 dias. Para análise das variáveis, foram realizadas análise descritiva e regressão logística simples (IC95%; p<0,05). Resultados: Foram analisados 204.130 casos que apresentaram média de idade de 55,8 anos (±13,24), sendo predominantemente do sexo feminino (99,1%), 55,1% eram da Região Sudeste e 71,4% residiam em cidades não capitais. A mediana do intervalo de tempo entre o diagnóstico e o início do primeiro tratamento oncológico foi de 63 dias (variação interquartil = 36-109). As variáveis sociodemográficas, clínicas e relacionadas ao tratamento mostraram impacto no intervalo de tempo, com exceção da variável sexo. Conclusão: O tempo entre o diagnóstico e o início do primeiro tratamento oncológico foi elevado. Fatores sociodemográficos, clínicos e relacionados ao tratamento influenciam nos intervalos de tempo. Identificá-los precocemente pode contribuir para o direcionamento de ações a esses grupos mais vulneráveis ao atraso.

Breast cancer is considered a public health problem with an increasing incidence worldwide. Several factors contribute to late diagnosis and hinder the initiation of the treatment, resulting in a worse prognosis. Objectives:To analyze the time interval between diagnosis and the beginning of the first oncologic treatment in the Brazilian population, in addition to assessing the factors associated with the longest time intervals. Method: Retrospective cohort study with 540,529 patients registered in the Hospital Cancer Registry System (SisRHC) from 2000 to 2017. The outcome was the time between diagnosis and the beginning of the first oncologic treatment, considering the interval greater than 60 days as delay. Descriptive analysis and simple logistic regression were performed (95% CI; p <0.05) to analyze the variables. Results: 204,130 cases were analyzed, mean age of 55.8 years (± 13.24), predominantly females (99.1%), 55.1% were from the southeast region and 71% lived in non-capital cities. The median of the time interval between diagnosis and the beginning of the first oncologic treatment was 63 days (interquartile range = 36-109). Sociodemographic, clinical and treatment-related variables affect the time interval, except the gender variable. Conclusion: The time between diagnosis and the beginning of the first oncologic treatment was high. Sociodemographic, clinical and treatment-related factors influence time intervals. Their early identification can contribute to guide the actions toward these most vulnerable groups to delay.

Introducción: El cáncer de mama se considera un problema de salud pública con una incidencia mundial creciente. Varios factores contribuyen al diagnóstico tardío y dificultan el inicio del tratamiento, resultando en un peor pronóstico. Objetivos:Analizar el intervalo de tiempo entre el diagnóstico y el comienzo del primer tratamiento oncologico en la población brasileña, además de evaluar los factores asociados con los intervalos de tiempo más largos. Método: Este es un estudio de cohorte retrospectivo con 540.529 pacientes registrados en el Hospital Cancer Registry System (SisRHC) desde 2000 hasta 2017. El resultado fue el intervalo de tiempo entre el diagnóstico y el comienzo del primer tratamiento oncologico, considerando como retraso el intervalo superior a 60 días. Para el análisis de las variables, se realizó un análisis descriptivo y una regresión logística simple (IC 95%; p <0,05). Resultados: Se analizaron 204,130 casos, con una edad media de 55,8 años (±13,24), predominantemente mujeres (99,1%), 55,1% de la región sureste y 71,4% residentes en ciudades no capitales.La mediana del intervalo de tiempo entre el diagnóstico y el comienzo del primer tratamiento contra el cáncer fue de 63 días (rango intercuartil = 36-109). Las variables sociodemográficas, clínicas y relacionadas con el tratamiento tuvieron un impacto en el intervalo de tiempo, con la excepción de la variable de género. Conclusión: El intervalo de tiempo promedio entre el diagnóstico y el comienzo del primer tratamiento oncologico fue alto. Además, se observó que los factores sociodemográficos, clínicos y relacionados con el tratamiento influyen en los intervalos de tiempo, por lo que identificarlos temprano puede contribuir a acciones directas para estos grupos más vulnerables al retraso.
