ABSTRACT
Cattle is one of the main items in the Brazilian productive guideline and an important export product. During the covid-19 pandemic, the price of beef occupied a prominent position in agricultural sector analyzes due to the prices increases. The objective of this research is to observe the national production behavior, exports, and domestic supply. Therefore, a domestic supply forecast was made for January 2021 to December 2022 (24 months). Based on the results obtained, it was found that the beefs supply available to the Brazilian market will not present an expressive upward behavior that compensates the evolution in beef export to international markets. Thus, a shift in the price of beef in the domestic market to higher levels may be observed.
ABSTRACT
BACKGROUND AND AIM: Sars-CoV-2 infection can lead to severe pulmonary impairment at all ages, however, the best therapy in children is not established. Our objective is to discuss a severe pulmonary case in a pediatric oncology patient who presented good clinical evolution and the therapeutic measures chosen in its management. METHOD(S): Case report and literature review. RESULT(S): A 2-year-old girl undergoing chemotherapy for acute lymphocytic leukemia had received cytarabine and methotrexate one week before being admitted to the ward for febrile neutropenia, identified with Sars-Cov-2 infection by RT-PCR. Referred to pediatric intensive care on day 3 of symptoms when she was prostrate and antibiotics switched to a broader spectrum. On day 8 of symptoms she rapidly developed respiratory failure and required mechanical ventilation at high parameters, CT scan showed lesions in ground glass in 75% of the lung parenchyma. On day 9, she was still feverish and showed altered inflammatory tests, such as ferritin 4492 mcg/L D-dimer 5909 ng/dL CRP 28 mg/ dL. Cardiac, hepatic and renal functions remained stable. At that moment, the patient received gammaglobulin 2g/kg in a single dose and methylprednisolone 2mg/kg/day for 5 days. Substantial improvement was observed 48 hours after the introduction of anti-inflammatory therapy, allowing for weaning and extubation after 7 days of mechanical ventilation. 72 hours after extubation, she was discharged home, breathing normally on room air. CONCLUSION(S): Severe Sars-Cov-2 lung infection in a pediatric oncology patient with markedly high inflammatory tests was treated with anti-inflammatory therapies such as steroids and gammaglobulin, with rapid and favorable recovery (Figure Presented).
ABSTRACT
Introduction: COVID-19 has affected the routine of health services, and there are few studies that address the practices of nurses in monitoring child health during the pandemi c period. Objective: To describe the practices of Brazilian nurses in monitoring child health at the beginning of the COVID-19 pandemic. Methods: Cross-sectional study carried out with 115 Brazilian nurses from Primary Health Care. The questionnaire sent by email and WhatsApp, included questions about activities for monitoring child health, aspects addressed in nursing care and the implementation of innovative strategies. Descriptive statistics were used for data analysis through Stata 15.1 software. Results: The majority of participants belonged to the family health strategy (75.65%) and were from the southeastern region of Brazil (40.87%). Child health monitoring activities were suspended or reduced in most Brazilian regions. Promotion of physical activity, guidance on playing, evaluation of food consumption and guidance on sleep quality were the least addressed aspects. Regarding the use of innovative strategies, phone calls and messages through WhatsApp were the most used. Conclusions: At the beginning of the pandemic, the nurses adapted their practices to innovative strategies to keep monitoring the child population, however, important health promotion actions for this pandemic period were little addressed. © 2022, Editorial Ciencias Medicas.

ABSTRACT
Purpureocillium lilacinum is a filamentous and hyaline fungus cosmopolitan, saprophytic, largely used in the biological control of plant-parasitic nematodes and insects, also considered an emerging and opportunistic human pathogen. The standard treatment for hyalohyphomycosis caused by P. lilacinum is not yet defined, since this fungus is resistant to different antifungals, in vitro and in vivo. The aim of this study was to evaluate and compare in vitro antifungal activity against environmental and clinical P. lilacinum isolates and our results demonstrated that these isolates can be resistant to newer generation triazoles, such as voriconazole, and to caspofungin, a drug of the echinocandin class. In summary, we highlight the importance of knowing the different susceptibility profiles of P. lilacinum isolates, and besides that, the emergence of uncommon human and animal opportunistic fungi, such P. lilacinum, especially during COVID-19, highlight the need for antifungal susceptibility testing of isolates since empirical therapy with different treatment schedules failed in great number of patients.

Purpose: COVID-19 causes lung inflammation and lesions, and chest X-ray and computed tomography images are remarkably suitable for differentiating the new disease from patients with other lung diseases. In this paper, we propose a computer model to classify X-ray images of patients diagnosed with COVID-19. Chest X-ray exams were chosen over computed tomography scans because they are low cost, results are quickly obtained, and X-ray equipment is readily available. Methods: A new CNN network, called CNN-COVID, has been developed to classify X-ray patient’s images. Images from two different datasets were used. The images of Dataset I is originated from the COVID-19 image data collection and the ChestXray14 repository, and the images of Dataset II belong to the BIMCV COVID-19+ repository. To assess the accuracy of the network, 10 training and testing sessions were performed in both datasets. A confusion matrix was generated to evaluate the model’s performance and calculate the following metrics: accuracy (ACC), sensitivity (SE), and specificity (SP). In addition, Receiver Operating Characteristic (ROC) curves and Areas Under the Curve (AUCs) were also considered. Results: After running 10 tests, the average accuracy for Dataset I and Dataset II was 0.9787 and 0.9839, respectively. Since the weights of the best test results were applied in the validation, it was obtained the accuracy of 0.9722 for Dataset I and 0.9884 for Dataset II. Conclusions: The results showed that the CNN-COVID is a promising tool to help physicians classify chest images with pneumonia, considering pneumonia caused by COVID-19 and pneumonia due to other causes. © 2021, Sociedade Brasileira de Engenharia Biomedica.
ABSTRACT
Objective: to identify the occurrence of the factors associated with: (1) suspected infection by the virus that causes COVID-19;(2) absenteeism at work due to suspected infection or diagnosis of infection by the virus that causes COVID-19;and (3) performance of tests for the screening of infection by the virus that causes COVID-19 among Nursing professionals. Method: a cross-sectional study conducted with 890 nurses in June and July 2020. The associations between the outcomes and the other variables were explored using Poisson regression models with robust variance estimators. Results: occurrence of the outcomes was (1) 35.5%, (2) 16.2% and (3) 38.2%, respectively. For suspected infection, associations were observed with assessment of the working conditions as deficient (RR: 1.55;95% CI: 1.21-1.99) and with lack of Personal Protective Equipment (RR: 1.27;95% CI: 1.06-1.51). Absenteeism at work was associated with the adoption of moderate social distancing (RR: 1.49;95% CI: 1.00-2.21). To perform the screening tests, the associations with links to outpatient (RR: 2.47;95% CI: 1.52-4.01) and hospital (RR: 2.49;95% CI: 1.60-3.89) services stood out, in addition to direct contact with patients with confirmed COVID-19 diagnoses (RR: 1.65;95% CI: 1.33-2.05). Conclusion: despite the high occurrence of suspected infection and a considerable incidence of absenteeism at work among professionals from the various services under study, disparity in access to the screening tests was evidenced, especially with regard to the professionals who work in Primary Care. © 2021, Universidade Federal de Santa Catarina.
