ABSTRACT Identifying Coffea arabica cultivars that are more efficient in the use of nitrogen is an important strategy and a necessity in the context of environmental and economic impacts attributed to excessive nitrogen fertilization. Although Coffea arabica breeding data have a multi-trait structure, they are often analyzed under a single trait structure. Thus, the objectives of this study were to use a Bayesian multitrait model, to estimate heritability in the broad sense, and to select arabica coffee cultivars with better genetic potential (desirable agronomic traits) in nitrogen-restricted cultivation. The experiment was carried out in a greenhouse with 20 arabica coffee cultivars grown in a nutrient solution with low-nitrogen content (1.5 mM). The experimental design used was in randomized blocks with three replications. Six agromorphological traits of the arabica coffee breeding program and five nutritional efficiency indices were used. The Markov Chain Monte Carlo algorithm was used to estimate genetic parameters and genetic values. The agromorphological traits were considered highly heritable, with a credibility interval (95% probability): H2 = 0.9538 – 5.89E-01. The Bayesian multitrait model presents an adequate strategy for the genetic improvement of arabica coffee grown in low-nitrogen concentrations. Coffee arabica cultivars Icatu Precoce 3282, Icatu Vermelho IAC 4045, Acaiá Cerrado MG 1474, Tupi IAC 1669-33, Catucaí 785/15, Caturra Vermelho and Obatã IAC 1669/20 demonstrated greater potential for cultivation in low-nitrogen concentration. fertilization multi structure Thus sense desirable nitrogenrestricted restricted 2 lownitrogen low 1.5 15 1 5 (1. mM. mM . mM) replications values heritable 95% 95 (95 probability probability) H 09538 0 9538 0.953 5.89E01. 589E01 E 5.89E 01. 89E 01 5.89E-01 concentrations 3282 4045 1474 166933, 166933 1669 33, 33 1669-33 78515 785 785/15 166920 1669/2 concentration 1.

Abstract Background In hospital settings, dermatology can offer substantial clinical support for the diagnosis and management of skin conditions, reducing morbidity and mortality. Thus, the study aimed to analyze the profile of referrals and consultations performed by the Dermatology Service of the Santa Casa de Misericordia de Porto Alegre, from August 2018 to January 2020. Methods This study is descriptive, quantitative, and retrospective, conducted through data collection and review of medical records and referrals. The variables included were clinical data of referrals, in-patients profiles, dermatological diagnoses, complementary exams, therapeutic conduct, and recommended follow-ups. Results A total of 1020 referrals were analyzed, which resulted in 641 consultations (328 men, 313 women). The most prevalent skin disease groups were ‘Dermatitis and Eczema’ (33.1%) and ‘Other infectious skin diseases (21.8%), while the most frequent ICD-10 were ‘Drug eruptions - L27’ (9.9%) and ‘Other and unspecified dermatitis - L30’ (6.6%). Corticoids were the most recommended treatments (27.7%), followed by antifungals (13.1%). ‘Consultation Discharge’ (44%) and ‘Outpatient’ Dermatology follow-up (27%) were the most frequent causes for ending consultation. Study limitations Among the study limitations, the authors highlight its retrospective nature, with data analysis based on referrals and medical records, which may present inaccurate or incomplete information. In addition to this, the study may demonstrate a certain degree of subjectivity due to the review and interpretation process conducted by the researchers. However, the definition of objective criteria based on previous studies attenuates such possible bias. Furthermore, considering that the Dermatology teams are composed of a preceptor dermatologist and residents, the established diagnoses were not submitted to third-party verification, except in the cases of skin biopsies and cultures. Thus, the professional’s experience and skills may have influenced the dermatological diagnoses. Conclusions These findings underlie the importance of Dermatology in hospital assistance, contributing to the management of a wide range of skin conditions. settings conditions mortality Thus Alegre 201 2020 descriptive quantitative inpatients patients profiles exams conduct followups. followups follow ups. ups follow-ups 102 analyzed 64 328 (32 men 31 women. women . women) Dermatitis Eczema 33.1% 331 33 1 (33.1% Other 21.8%, 218 21.8% , 21 8 (21.8%) ICD10 ICD 10 ICD-1 Drug L27 L 9.9% 99 9 (9.9% L30 6.6%. 66 6.6% 6 (6.6%) 27.7%, 277 27.7% 27 7 (27.7%) 13.1%. 131 13.1% 13 (13.1%) Consultation Discharge 44% 44 (44% ‘Outpatient Outpatient followup up 27% (27% consultation nature information this researchers However bias Furthermore residents thirdparty third party verification cultures professionals professional s assistance 20 202 32 (3 3 33.1 (33.1 21.8 2 (21.8% ICD1 ICD- L2 9.9 (9.9 L3 6.6 (6.6% 27.7 (27.7% 13.1 (13.1% 4 (44 (27 ( 33.

Abstract Objectives: to analyze a decade of spatio-temporal behavior of pertussis in Brazil and its epidemiological characteristics. Methods: ecological time series study of pertussis cases and deaths from the Notifable Diseases Information System in Brazil (2010-2019). The method of generalized linear analysis of Prais-Winsten and the Kernel analysis were used. Results: 32,849 cases were reported, of which 466 (1.42%) evolved to death, with a prevalence of 1.63/100,000 inhabitants and a mortality rate of 0.023/100,000 inhabitants. In the temporal analysis, the cyclical behavior of pertussis was evidenced, with trend variations in the period in 2014. Most cases occurred in children under 1 year of age (60.16%, p<0.01), sex female (55.28%, p=0.066) and white (48.42%, p=0.14). The largest share of deaths was in children aged <1 year (98.07, p<0.01), females (56.01%, p=0.066) and whites (43.78%, p=0.14). In the Kernel of prevalence, the South, Southeast and Northeast regions stood out with high density; while for mortality, the Southeast and Northeast stood out. Conclusions: the cyclical behavior of pertussis was observed, with a decreasing trend in recent years and the concentration of cases in children. This reinforces the importance of strengthening the population’s immunization process.

ABSTRACT: The most widely used method to classify prognostic factors in cancers today is TNM. However, Oral Squamous Cell Carcinoma (OSCC) often demonstrates different behaviors in relation to aggressiveness and therapeutic response at the same TNM stage. So, in such cases biomarkers can be used to identify the biological diversity of these tumors more reliably, leading to better therapeutic strategies and disease management. The presence of inflammatory immune cells in the tumor microenvironment can have pro or antitumor effects and the investigation of the expression of inflammatory markers in OSSC can be usefulto design immunotherapeutic interventions. The Transforming Growth Factor alpha is a potent stimulator of cell migration that acts on cell proliferation, invasion and metastasis of cancer, as well as immune suppression and angiogenesis. Inflammatory cytokines, such as Interferon-gamma, mediate macrophage differentiation. Macrophages are an important component of the OSCC microenvironment. The greater amount of tumor-associated macrophages, especially the M2 phenotype, may be associated with a more aggressive biological behavior of the OSCC and, consequently, with reduced survival.

RESUMEN: El método más utilizado para clasificar los factores de pronóstico en los cánceres en la actualidad es TNM. Sin embargo, el carcinoma oral de células escamosas (COCE) a menudo muestra diferentes comportamientos en relación con la agresividad y la respuesta terapéutica en la misma etapa TNM. Entonces, en tales casos, los biomarcadores pueden usarse para identificar la diversidad biológica de estos tumores de manera más confiable, lo que lleva a mejores estrategias terapéuticas y manejo de la enfermedad. La presencia de células inmunes inflamatorias en el microambiente tumoral puede tener efectos pro o antitumorales y la investigación de la expresión de marcadores inflamatorios en COCE puede ser útil para diseñar intervenciones inmunoterapéuticas. El factor de crecimiento transformante α es un potente estimulador de la migración celular que actúa sobre la proliferación celular, la invasión y metástasis del cáncer, así como la inmunosupresión y la angiogénesis. Las citocinas inflamatorias, como el IFN-γ, median en la diferenciación de macrófagos. Los macrófagos son un componente importante del microambiente COCE. La mayor cantidad de macrófagos asociados a tumores, especialmente el fenotipo M2, puede estar asociada a un comportamiento biológico más agresivo del COCE y, en consecuencia, a una menor supervivencia.

ABSTRACT Dark carbon fixation (DCF) is a source of new and labile carbon in the deep ocean, while heterotrophic microbial production (HMP) promotes organic matter transfer through the microbial loop. Despite their ecological relevance, there is a scientific gap regarding the estimates of DCF and HMP in the Southwestern Atlantic Ocean. Thus, the aim of this study was to investigate the spatial distribution of DCF and HMP; their relevance to the ocean carbon cycle; their relationship with environmental parameters and amongst themselves on the upper slope of Santos Basin. The samples were collected at three different water depths and sediment layers aboard the R/V Alpha Crucis in November 2019. DCF and HMP rates were measured by 14C-bicarbonate and 3H-leucine incorporation, respectively, and incubated in the dark. In the water column, DCF rates varied from 1.51 x 101 to 3.24 x 102 µg C m-3 h-1, which were one to two orders of magnitude lower than the HMP rates, from 1.26 x 102 to 1.48 x 104 µg C m-3 h-1. In the sediments, the DCF ranged from 1.15 x 104 to 1.83 x 105 µg C m-3 h-1, while HMP was one to four orders of magnitude lower, 3.22 x 101 to 1.56 x 103 µ gC m-3 h-1. DCF rates were significantly higher in the sediments, due to a higher availability of energy sources than in the oligotrophic water above. The HMP had higher rates in the water column as it is deeply dependent on organic matter derived from photosynthesis. This is the first study to investigate DCF and HMP considering the water column and sediments of the Southwestern Atlantic Ocean, thus contributing to a better understanding of the microbial role in the marine carbon cycle and ecosystem functioning.

Abstract Pockmarks are geological features that often sustain hydrocarbon-related communities of microorganisms when active, seeping oil or methane. Microbial communities of inactive pockmarks have not been well studied until the present. Plenty of pockmarks in the Southwestern Atlantic Ocean have been discovered. However, no information is available about the organic characteristics in association with the microbial diversity related to methane and non-methane hydrocarbon consumption. This study examined the identity and potential ecology of the methane-related microbial community in an inactive SW Atlantic Carbonate-enriched Pockmark (SWACP). Undisturbed sediment cores were enriched with CH4 99.5% at 5°C, with samples harvested at 16h, 120h, 240h, 720h, and 960h, followed by metataxonomics functional prediction, and the correlation of microbial groups with incubation and enrichment types. The SWACP is depleted in organic compounds, and chemosynthetic production is dominant. Incubated mini-cores of sediment were affected by incubation time and enrichment type, which influenced the microbial composition. Although several taxa were shared among all sediment samples, specific groups per enrichment type and incubation time were observed. These communities comprised taxa previously reported in marine bottom waters, carbonate crusts, active cold-seeps, and inactive pockmarks. The methane-enriched taxa were predominantly related to aerobic methanotrophy, methylotrophy, aerobic and anaerobic non-methane hydrocarbon degradation, and fermentation. This study brings the first survey of the key microbial groups in methane fluxes of a Brazilian deep-sea pockmark, providing data for understanding the ecology surrounding the SW Atlantic gas field areas.

ABSTRACT Worldwide, transplant programs have suffered a setback during the coronavirus disease 2019 (COVID-19) pandemic and most have temporarily suspended their transplant activities. . We identified 36 liver transplant patients who tested positive for COVID-19. The cases were confirmed by the nucleic acid test (RT-PCR). Epidemiological, demographic, clinical, laboratory, management and outcome data were obtained from the patients’ medical records. Fourteen patients (38.9%) required admission to the Intensive Care Unit and/or invasive ventilatory support (severe cases). The mean age of these severe cases was 63.8 years. Regarding the time since the transplant, 71.4% (10/14 patients) had undergone the procedure less than one year before. The immunosuppressive therapy was reduced in patients who required Intensive Care Unit. A total of 12 cases (12/14, 85.7%) required invasive ventilatory support. Eight cases (8/14, 57.1%) required renal replacement therapy. In this group of patients, nine died (64.3 %). In turn, 22 patients had mild to moderate symptoms of COVID-19, not requiring invasive ventilatory support or admission to the Intensive Care Unit. The mean age in these patients was 56.5 years and comorbidities were present in 15 (68.2%) of the cases. In this group, only five patients (5/22, 22.7%) required hospitalization due to complications and there were no deaths This report describes the results of COVID-19 infection in a very specific population, suggesting that liver transplant patients have a significant higher risk of progressing to severeCOVID-19 , with a mortality rate among critically-ill patients above that of the general population.

Abstract Our hypothesis was that different sources of unsaturated fatty acids from oilseeds (sunflower, soybeans, and cottonseed) could alter milk yield, fatty acid profile, and the amount of unsaturated fatty acids yielded in milk. It aimed to evaluate the effects of lipid sources on yield and composition and fatty acids in milk of primiparous Girolando cows. Five cows in lactation (35 ± 8 days), with 410 ± 7.15 kg BW were randomly distributed in a 5 x 5 Latin square. Five experimental diets, namely a control diet without an additional source of lipid and four diets with different lipid sources: cottonseed, sunflower seed, whole soybean, or soybean oil, as lipid source, to reach 70 g/kg of ethereal extract dry matter basis were used. Cottonseed and soybean oil addition reduced daily yield by 15 and 22%. Oilseed can alter fatty acid profile in milk. Whole soybean provided greater daily milk and fatty acids yields.

ABSTRACT Although sporotrichosis requires a broad approach for control, few reports have described the relationship between the index case and secondary contacts. In the present work, we report an outbreak involving a woman, a dog, and two cats from the same household environment, including the clinical and epidemiological aspects and outcomes, and discuss the importance of a One Health approach to face this neglected disease. The joint efforts of professionals such as veterinarians and physicians are essential for early diagnosis and surveillance, which contributes to the rapid identification and control of zoonotic sporotrichosis outbreaks.

One of the recurrent problems of the agroindustry sector is the incorrect disposal of waste because of the complexity of the material, moisture, among other factors. Waste is not used in tonnage, but is systematically used. Examples of residues are malt bagasse and cassava peel, produced in large quantities in the brewing industry and flour production, respectively. In this context, the objective of this study was to evaluate bioactive compounds of flours produced from agroindustry waste to potentiate their use as an ingredient rich in antioxidants. The flours produced from agroindustry waste were evaluated for phenolic compounds, total carotenoids, antioxidant activity, and the attainment of phenolic profiles and fingerprints by paper spray mass spectrometry. It was possible to identify a broad class of compounds in both flours, such as phenolic acids, flavonoids, among others. The flours can be possibly included in food commodities or packaging formulation since they are natural antioxidants, thus adding value to these products and reducing environmental issues. However, further analysis is needed to ensure bioavailability as well as food safety.

Abstract Objectives To evaluate the impact of invasive mechanical ventilation associated with two serum inflammatory cytokines and clinical indicators, on the second day of life, as predictors of bronchopulmonary dysplasia in very low birth weight preterm infants. It was hypothesized that the use of invasive mechanical ventilation in the first hours of life is associated with biomarkers that may predict the chances of preterm infants to develop bronchopulmonary dysplasia. Methods Prospective cohort of 40 preterm infants with gestational age <34 weeks and birth weight <1500 g. The following were analyzed: clinical variables; types of ventilator support used (there is a higher occurrence of bronchopulmonary dysplasia when oxygen supplementation is performed by long periods of invasive mechanical ventilation); hospitalization time; quantification of two cytokines (granulocyte and macrophage colony stimulating factor [GM-CSF] and eotaxin) in blood between 36 and 48 h of life. The preterm infants were divided in two groups: with and without bronchopulmonary dysplasia. Results The GM-CSF levels presented a significantly higher value in the bronchopulmonary dysplasia group (p = 0.002), while eotaxin presented higher levels in the group without bronchopulmonary dysplasia (p = 0.02). The use of continuous invasive mechanical ventilation was associated with increased ratios between GM-CSF and eotaxin (100% sensitivity and 80% specificity; receiver operating characteristic area = 0.9013, CI = 0.7791–1.024, p < 0.0001). Conclusions The duration of invasive mechanical ventilation performed in the first 48 h of life in the very low birth weight infants is a significant clinical predictor of bronchopulmonary dysplasia. The use of continuous invasive mechanical ventilation was associated with increased ratios between GM-CSF and eotaxin, suggesting increased lung injury and consequent progression of the disease.

Abstract Composites based on recycled high-density polyethylene (rHDPE) and muscovite mica, with different rHDE/mica ratios (100/0, 95/5, 90/10, 85/15 and 80/20, weight percentage) were prepared in an internal mixer with roller-type rotors at temperature of 170 ºC for 10 minutes. The materials obtained were characterized by tests of density, Shore hardness D and melt-flow index, along with infrared spectroscopy, thermogravimetry, differential scanning calorimetry and scanning electron microscopy. The hardness analysis confirmed the action of mica as a reinforcing load in the matrix, but this effect stabilized at around 15%. The TG analysis showed that the 85/15 composite presented slightly better performance than the 80/20, indicating that mica, up to 15%, caused disorganization of the polymer structure instead of reinforcing it. The DSC results revealed that the composites had slightly lower melting temperatures than the matrix. The FTIR spectrum indicated there was no chemical interaction between the rHDPE and mica.

Methods: data from confirmed cases of COVID-19 was obtained between February 13 and June 19, 2020, in Pernambuco, Brazil. The K-fold Cross Validation algorithm (K=10) assessed RF performance and the importance of clinical features. Results: the RF algorithm correctly classified 78.33% of the elderly people, with AUC of 0.839. Advanced age was the factor representing the highest risk of death. The main comorbidity and symptom were cardiovascular disease and oxygen saturation ≤ 95%, respectively. Conclusion: this study applied the RF classifier to predict risk of death and identified the main clinical features related to this outcome in elderly people with COVID-19 in the state of Pernambuco.

Objetivou-se identificar o estado nutricional, a satisfação e aceitação da dieta hospitalar. Estudo de delineamento transversal, com 50 pacientes diagnosticados com alguma patologia cardiovascular. Foi realizada a identificação do estado nutricional através dos questionários Avaliação Nutricional Subjetiva Global (ANSG), Nutritional Risk Screening (NRS-2002), e através do IMC, comparando os diferentes métodos. Depois foi aplicado outro questionário para identificação da satisfação e da ingestão da dieta oferecida, adaptado de Pfaffenzeller. De acordo com a ANSG nenhum paciente foi constatado com desnutrição, já o NRS-2002 mostrou que 30% dos pacientes estavam em risco nutricional; o IMC mostrou que 52% dos pacientes estavam acima do peso recomendado. Sobre as variáveis que influenciaram na aceitação da dieta, percebeu-se que 80% dos pacientes estavam com o apetite preservado, e 52% faziam uso de sal reduzido antes da internação. Os pacientes relataram estar satisfeitos com a dieta oferecida, tanto no almoço (87,6%) como no jantar (80%). Sobre a quantidade, a maioria dos pacientes consumiram as refeições completamente, no almoço (66%) e jantar (68%). A NRS-2002 mostrou-se mais eficiente no rastreio do risco nutricional, quando comparada a ANSG. Os pacientes apresentaram boa aceitação da dieta oferecida, tanto em relação as variáveis como em relação a quantidade ingerida.

The objective was to identify the nutritional status, satisfaction and acceptance of the hospital diet. Cross-sectional study with 50 patients diagnosed with some cardiovascular disease. Nutritional status was identified through the Global Subjective Nutrition Assessment (ANSG) and Nutritional Risk Screening (NRS-2002) questionnaires, and also through BMI, comparing the different methods. Then another questionnaire was applied to identify the satisfaction and intake of the diet offered, adapted from Pfaffenzeller. According to the ANSG, no patient was found to be malnourished, whereas the NRS-2002 showed that 30% of the patients were at nutritional risk; The BMI showed that 52% of the patients were overweight recommended. Regarding the variables that influenced the acceptance of the diet, it was observed that 80% of the patients had their appetite preserved, and 52% used reduced salt before hospitalization. Patients reported being satisfied with the diet offered, both at lunch (87.6%) and at dinner (80%). About the amount, most patients consumed meals completely, at lunch (66%) and dinner (68%). NRS-2002 was more efficient in the screening of nutritional risk when compared to ANSG. The patients showed good acceptance of the diet offered, both in relation to the variables and in relation to the amount ingested.
