The worldwide emergence of viral diseases such as Zika, Dengue, Chikungunya, West Nile and Yellow Fever urge the search for solutions to eliminate their common vector, the Aedes aegypti mosquito. This paper describes the quantitative structure-activity relationship (QSAR) and docking studies of a series of nine 3-(3-aryl-1,2,4-oxadiazol-5-yl)propionic acids (AOPA), 1-9, previously published by our group. Additionally, three new 1,2,4-oxadiazoles, 10-12, have also been synthesized, characterized and studied. The QSAR and docking studies of all compounds, 1-12, clearly indicate that larger hydrophobic substituents such as biphenyl groups attached on position 3 in 1,2,4-oxadiazoles improve the larvicidal activity. It is worthwhile to mention that nanocapsulation of compounds 10-12 were necessary to help their dissolution in water and these three new 1,2,4-oxadiazoles also exhibited approximately equal or higher larvicidal activities compared to the former prototypes at stage L4.

ABSTRACT Introduction: COVID-19 has shown great clinical and epidemiological variability. Objective: The aim of this study was to describe the sociodemographic and clinical-epidemiological characteristics of COVID-19 in a high-altitude population of Perú. Materials and methods: Observational and retrospective study. The population consisted of ambulatory patients diagnosed with COVID-19 from a primary care health facility located at an altitude of 3850 meters above sea level. Documentary analysis of medical records was carried out. Data analysis was descriptive in terms of percentages and measures of central tendency. Results: The study included 154 patients, mostly female (56.5%), adults (51.3%), and housewives (37.0%). The most frequent and longest-lasting symptoms were cough (80.5%, 6.3 days), sore throat (61.7%, 3.6 days), and headache (58.4%, 3.5 days). The most common clinical classification was mild (69.5%). The most common comorbidities were pregnancy (14.5%), hypertension (8.25%), and obesity (5.5%). Oxygen saturation in the elderly was on average the lowest (84.5), while in adolescents it was on average the highest (90). Conclusion: Women, adult housewives, and those with comorbidities such as pregnancy, hypertension, and obesity were most affected. The most frequent and longest-lasting symptoms were cough, sore throat, and headache. Oxygen saturation decreased with age.

ABSTRACT BACKGROUND: The prevalence of primary sclerosing cholangitis (PSC) in the general population has not yet been clearly established. The management of PSC should focus on delaying the progression of the disease and restraining its complications. The only curative therapy for the disease remains liver transplantation (LT). PSC is currently the fifth most common indication for LT and corresponds to 5% of all LT indications in adults. AIMS: Our objective is to evaluate the indications and outcomes of PSC patients undergoing LT in three liver transplantation centers in southern Brazil – Hospital Santa Isabel in Blumenau, Santa Catarina state, and Hospital das Clínicas and Hospital Nossa Senhora das Graças, in Curitiba, Parana state). METHODS: This is a longitudinal observational study of patients with PSC who underwent LT in three major Brazilian medical centers. Electronic medical records and study protocols of all patients subjected to LT from January 2011 to December 2021 were retrospectively reviewed. RESULTS: Of the 1,362 transplants performed in the three medical centers, 37 were due to PSC. Recurrence of PSC occurred in three patients (8.1%) in 3.0±2.4 years (range, 1–4 years). The 1-year and 5-year survival rates after the first LT were 83.8 and 80.6%, respectively. The 1-year and 5-year graft survival rates were, respectively, 83.8 and 74.8%. CONCLUSIONS: Our experience with LT in patients with PSC demonstrated good patient and graft survival results. Most deaths were due to common factors in patients undergoing LT.

RESUMO RACIONAL: A prevalência de colangite esclerosante primária (CEP) na população em geral ainda não foi claramente estabelecida. O manejo da CEP deve se concentrar em retardar a progressão da doença e gerenciar suas complicações. A única terapia curativa para a doença continua sendo o transplante hepático (TH). A CEP é atualmente a 5ª indicação mais comum de TH e corresponde a 5% de todas as indicações de TH em adultos OBJETIVOS: O nosso objetivo é avaliar as indicações e os resultados do transplante de fígado em pacientes com CEP submetidos a TH em três centros de transplante de fígado no sul do Brasil (Hospital Santa Isabel, Blumenau, Santa Catarina; Hospital das Clínicas, Curitiba, Paraná; e Hospital Nossa Senhora das Graças, Curitiba, Paraná). MÉTODOS: Este é um estudo observacional longitudinal de pacientes com colangite esclerosante primária que foram submetidos a transplante hepático em três grandes centros médicos brasileiros. Os prontuários eletrônicos de todos os pacientes submetidos a TH de Janeiro de 2011 a Dezembro de 2021, foram avaliados retrospectivamente. RESULTADOS: De um total de 1.362 transplantes realizados nos três centros médicos, 37 eram devidos à CEP. A recorrência de CEP ocorreu em 3 pacientes (8,1%) em 3±2,4 anos (intervalo, 1–4 anos). A taxa de sobrevida de 1 ano e 5 anos após o 1° TH foi respectivamente de 83,8 e 80,6%. As taxas de sobrevida dos enxertos em 1 ano e 5 anos foram, respectivamente, 83,8 e 74,8%. CONCLUSÕES: A nossa experiência com TH em pacientes com CEP demonstrou bons resultados de sobrevida dos pacientes e dos enxertos. A maioria dos óbitos ocorreu devido a fatores comuns em pacientes submetidos a TH.

The demand for new advanced high strength steels (AHSS) has been increasing in the last few decades. A large part of this demand comes from automotive companies. We have produced a new complex-phase (CP) steel with 1200 MPa of mechanical resistance and 8% of elongation, called CP1200. In this paper the dilatometric and microstructural characterization of a newly produced CP1200 steel is presented. The new steel was produced by making changes to the heat treatment of the already industrially available CP1100. The microstructure was quantified using light optical microscopy (LOM) and electron backscatter diffraction (EBSD). The microstructure of both steels was compared to identify the origin of the mechanical properties improvement. A new microstructure distribution, with higher amount of bainite and smaller concentration of ferrite and martensite was identified.

ABSTRACT Compaction caused by mechanization affects soil quality and, consequently, the development of crops. This study aimed to evaluate the effect of different degrees of soil compaction on the physiology, morphology, and anatomy of different coffee cultivars in a controlled environment. The experiment was carried out in a greenhouse, with randomized block design in a 5 × 5 factorial arrangement, with five coffee cultivars (Arara, Catuaí Amarelo IAC 62, Catuaí Vermelho 144, MGS Paraíso 2 and Mundo Novo IAC 379-19) and five degrees of compaction (68, 74, 80, 86 and 92 %), with four repetitions, totaling 100 experimental units. The following variables were evaluated in the aboveground biomass: plant height, number of leaves, diameter of the orthotropic branch, fresh mass of leaves and stem, leaf area, gas exchange, and chlorophyll a and b index; in the roots: length, surface area, volume, diameter of fine and coarse roots, fresh and dry mass of roots, as well as anatomical characteristics. Results showed that soil with degrees of compaction above 80 % negatively affected the variables evaluated. Catuaí Vermelho 144 presented the worst performance regardless of the degree of compaction, while Arara and MGS Paraíso 2 showed the best performance under the evaluated compaction degrees. Anatomical structure of the roots was modified with soil compaction, and no differences were observed among cultivars.

ABSTRACT. Analyzing the organochlorine pesticide (OCP) content in milk is relevantbecause it helps evaluate the quality of milk that reaches the consumer's table and also helps identify the geographical areas where there is a high possibility of contamination. Accordingly,thispilot project was aimed at determining the extent of contamination by OCP residues and their metabolites in fresh cow's milk in Mojuí dos Campos and Belterra, Pará, using solid-phase extraction (SPE) and gas chromatography coupled with electron capture detection (GC-ECD). The OCPs evaluated in this study weredichlorodiphenyltrichloroethane (DDT) and its metabolites (dichlorodiphenyldichloroethylene (DDE) and dichlorodiphenyldichloroethane (DDD)), hexachlorocyclohexane (HCH) (α, β, γ, and δ), endosulfanα and β, andendosulfansulfate. None of the thirty bovine milk samples analyzedshowed any contamination with OCPs.TheOCP content was within the limit of quantification of the method. The results of this study add to the existing knowledge on the quality ofbovine milk produced in these locations. However, further researchon other environmental matricesis required to confirm the results obtained in this study.

Resumen: Introducción: la obesidad es una pandemia de alta mortalidad. Su tratamiento es multidisciplinario y tiene como base el cambio del estilo de vida con un beneficio limitado, por lo que en la mayoría de los casos es necesario realizar otras intervenciones. El uso de dispositivos intragástricos colocados por endoscopia es un método en el tratamiento para la pérdida de peso, principalmente cuando el paciente no es apto o no acepta una intervención quirúrgica. Objetivo: evaluar los resultados del tratamiento con el dispositivo intragástrico Spatz-3® en un periodo de cuatro a 12 meses. Material y métodos: se analizaron los resultados de un estudio longitudinal para evaluar la eficacia del dispositivo intragástrico Spatz-3® en un centro endoscópico privado en el norte de México. Se analizaron 27 pacientes del género femenino en un periodo comprendido entre enero de 2019 y diciembre de 2021, a quienes se les colocó el dispositivo Spatz-3®. Resultados: se observó una disminución del peso total en promedio de 14.2 kg (14.6% del peso total corporal y 37.6% del exceso de peso perdido) a los 12 meses. Aunque estos resultados están por debajo de lo reportado por otros estudios con tratamiento quirúrgico (manga gástrica, bypass gástrico), el dispositivo intragástrico tiene una efectividad más alta comparada con las intervenciones conservadoras basadas en el cambio del estilo de vida del paciente. Conclusión: el dispositivo intragástrico Spatz-3® mostró una reducción considerable del peso total, siendo además un método con menor tasa de complicaciones y completamente reversible.

Abstract: Introduction: obesity is a high-mortality pandemic. Its treatment is multidisciplinary and is based on lifestyle changes with limited benefit. The use of intragastric devices is a treatment for weight loss, especially when the patient is unfit or denies surgery. Objective: to evaluate the results of treatment with the intragastric device Spatz-3® in a period of 12 months. Material and methods: a longitudinal study is carried out to evaluate the efficacy of the intragastric device Spatz-3® in a private endoscopic center in northern Mexico; and 27 female patients were analyzed between January 2019 and December 2021. Results: an average decrease in total weight of 14.2 kg (14.6% of total body weight and 37.6% of excess weight lost) was observed at 12 months. Despite a lower effectiveness than that reported in surgical treatment, DIG has a higher effectiveness compared to conservative interventions based on changing the patient’s lifestyle. Conclusion: the intragastric device Spatz-3® showed a considerable reduction in total weight, being also a method with a lower rate of complications and completely reversible.

Resumo O objetivo deste trabalho foi quantificar os compostos fenólicos totais no mel monofloral de aroeira (Astronium urundeuva) e verificar, por meio de testes histoquímicos, se estes compostos estão presentes nos tecidos florais. O apiário, com abelhas Apis mellifera, foi instalado em meio a aroeiras, na região do semiárido do estado de Minas Gerais, Brasil. A partir da anatomia das flores e da raque da inflorescência, observou-se epiderme ornamentada, tricomas tectores e glandulares, idioblastos e sistema secretor desenvolvido. O mel de aroeira apresenta, em média, 142.5±22.6 mg 100 g-1 de compostos fenólicos totais, valor considerado muito elevado quando comparado aos de outros méis monoflorais provenientes do Brasil e do mundo. Os testes histoquímicos detectaram a presença de substâncias fenólicas nos idioblastos e nos ductos secretores associados ao floema nos tecidos florais, especialmente no parênquima nectarífero, na epiderme e nos tricomas glandulares. Os compostos fenólicos estão presentes no tecido floral de ambos os morfos florais, principalmente no nectário onde as abelhas coletam o néctar. Os resultados obtidos são os primeiros, na literatura, indicativos de que os compostos fenólicos produzidos pelas árvores de aroeira são transferidos através do néctar para o mel. Este estudo contribui para o estabelecimento de padrões de qualidade do mel de aroeira e para a identificação da sua origem botânica.

Abstract The objective of this work was to quantify the content of total phenolic compounds in monofloral honey from aroeira (Astronium urundeuva) trees and to verify, through histochemical tests, if these compounds are present in the floral tissues. The apiary, with Apis mellifera bees, was installed among aroeira trees in the semiarid region of the state of Minas Gerais, Brazil. From the anatomy of the flowers and of the inflorescence rachis, an ornamented epidermis, tector and glandular trichomes, idioblasts, and a developed secretory system were observed. Aroeira honey has an average phenolic content of 142.5±22.6 mg 100 g-1, a value considered very high when compared with those of other monofloral honeys from Brazil and around the world. Histochemical tests detected the presence of phenolic substances in the idioblasts and secretory ducts associated with the phloem in the floral tissues, especially in the nectar parenchyma, epidermis, and glandular trichomes. Phenolic compounds are present in the floral tissue of both floral morphs, mainly in the nectary where honeybees collect nectar. The obtained results are the first, in the literature, indicative that the phenolic compounds produced by aroeira trees are transferred through the nectar to the honey. This study contributes to the establishment of quality standards for monofloral aroeira honey and to the identification of its botanical origin.

ABSTRACT Selection indexes represent the real efforts of a breeding program to obtain genetic gains for various significant traits simultaneously. As such, this study selected superior F5 lines by combined selection for fruit quality using an index based on predicted genotypic values via residual or restricted maximum likelihood/best linear unbiased prediction (REML/BLUP) methodology weighted by agronomic weights. To do so, 97 F5 papaya lines obtained by the single seed descent method, resulting from the biparental cross between the genotypes JS-12 and Sekati, were evaluated for the main traits related to fruit quality. Results of the analysis of deviance and the genetic parameters indicated that there was genetic variability, indicating possible success in the selection process. Based on the selection index, 29 lines were selected as superior for fruit quality with ‘Formosa’ pattern. The strategy of the selection index combining BLUPs of multiple traits of interest associated with agronomic weights allows maximizing genetic progress while discarding less-promising genotypes.

ABSTRACT COVID-19 has become the main problem facing the government. In this scenario, geographic information systems through thematic zone maps can be tools for decision-making in municipal public management. The purpose is to identify areas at risk of COVID-19 infection, through the use of spatial data as a tool for public management in the city of Juliaca. In the first stage the coordinates of the banking equipment have been located and classified into 5 types, the second stage develops the spatial analysis through the density of Kernel to obtain the partial maps, in the third stage the partial maps are added through the map algebra and reclassified into the values of high, high-moderate, moderate, low-moderate and low risk of contagion. The red area catalogued as high risk of infection COVID-19 has an area of 74042.89 m2 which represents 3% of the study area covering 8 blocks around this due to the large accumulation of banking equipment in the center of the city that caused inequality with other sectors of the city of Juliaca.

SUMMARY OBJECTIVE: The aim of this study was to determine the prospective capacity and impact of donor risk index, preallocation survival outcomes following liver transplant, donor model for end-stage liver disease, and balance of risk on patients’ 30-day survival after liver transplantation. METHODS: We prospectively analyzed patient survival in a multicentric observational cohort of adult liver transplantation through the year of 2019 at the state of Paraná, Brazil. The receiver operating characteristic curve, the area under the curve, and the best cutoff point (i.e., the Youden’s index) were estimated to analyze the prognostic value of each index. RESULTS: In total, 252 liver transplants were included with an average model for end-stage liver disease score of 21.17 and a 30-day survival of 79.76%. The donor risk index was the only prognostic variable with no relation to patients’ 30-day mortality model for end-stage liver disease and donor model for end-stage liver disease have no prognostic value on receiver operating characteristic curve, but preallocation survival outcomes following liver transplant, survival outcomes following liver transplant, and balance of risk presented good relationship with this observation. The cutoff value was estimated in 11-12 points for balance of risk and 9-12 for preallocation survival outcomes following liver transplant and survival outcomes following liver transplant. The 30-day survival for the group of transplants with scores up to 12 points (n=172) in all the three indexes was 87.79%, and for those transplants with scores higher than 12 it was 36.36%. CONCLUSIONS: The 30-day survival is 79.76%, and balance of risk, survival outcomes following liver transplant, and preallocation survival outcomes following liver transplant are the good prognostic indexes. The cutoff value of 12 points has clinical usefulness to predict the post-liver transplantation results.

ABSTRACT BACKGROUND: Overweight and obesity have reached epidemic prevalences. Obesity control involves many factors and needs to begin early in childhood. OBJECTIVES: To ascertain the association between tracked extracurricular sports practice and weight status; and to analyze tracking of overweight and obesity among school-aged children. DESIGN AND SETTING: Prospective cohort study conducted in 13 public schools in Cianorte, Paraná, in 2012-2016. METHODS: The sample comprised 2459 schoolchildren in Cianorte, of mean age 6.3 years at baseline and 9.4 years at follow-up. Body mass index was calculated from body mass and height measurements. The children were grouped as normal weight, overweight or obese. Information on extracurricular sports practice was collected through the dichotomous question “Do you participate in any extracurricular sports?” (“yes” or “no”). RESULTS: Tracking of weight status showed that 75.5% maintained this, with kappa of 0.530. Tracking of extracurricular sports practice showed that 80.9% maintained this, with low concordance (kappa of 0.054). Weight status correlation between baseline and follow-up showed that overweight or obese individuals were 4.65 times (CI: 4.05-5.34) more likely to maintain the same classification or move from overweight to obese at follow-up. Correlation of extracurricular sports practice with overweight or obesity at follow-up was not significant. CONCLUSIONS: These results demonstrated that overweight or obese children were at higher risk of gaining weight than were normal-weight children. In addition, the proportion of these children who maintained extracurricular sports practices over the years was low. Maintenance of this variable was not associated with weight status.

Abstract Aim: The aim was to compare performance in specific-skill tests and motor coordination between groups with different technical efficiency and verify possible variables related to specific skills and motor coordination that contribute to discriminate players into high- and low-technical efficiency. Methods: The sample consisted of 82 young soccer players (12-15 years). Body size, bone age, motor performance tests, soccer-specific skill tests, and frequency of technical actions in SSG were analyzed. Statistic cluster-derived ANOVA F was used to identify which variables related to technical action most contributed to classifying subjects with similar performance. Discriminant analysis (Stepwise Method) was used to verify which predictor variables discriminated players into groups of low- and high-frequency technical actions in SSG. Statistical significance was set at 5%. Results: The group of high technical efficiency presented better performance in motor tests, shuttle run (P = 0.04; ES = −0.55), jumping laterally (P = 0.02; ES = 0.58), kicking speed (P = 0.03; ES = 0.60), soccer-specific skill tests, leading the ball in a straight line (LBSL) (P = 0.01; ES = −0.75), and zig-zag ball control (ZZBC) (P = 0.04; ES = −0.55); variable leading the ball in a straight line correctly discriminated 60% of players into high- and low-frequency groups. Conclusion: The frequency of technical actions in SSG was poorly influenced by motor performance and specific skill tests, and only the LBSL test correctly classified players of different frequencies of technical actions in SSG.
