ABSTRACT
Seed treatment is important for protecting seed and seedling from pests and/ or pathogens. Seed treatment can be performed generally in two ways: industrial seed treatment (IST), performed by seed companies, or on-farm treatment (OFT). These treatment technologies will affect the final quality of the process. Therefore, the objective of this study was to characterize the seed quality profile of ISTs and OFTs in Brazilian agribusiness in terms of functional quality and dose application effectiveness (DAE). Seed samples treated by both processes were collected in 6 producing states of Brazil, Mato Grosso, Goias, Parana, Minas Gerais, Sao Paulo, and Santa Catarina. To evaluate the functional quality of the treatments, the coating percentage was determined by high-resolution image analysis with GroundEye (R) equipment, and the insecticide active ingredient DAE amount was determined with high-performance liquid chromatography (HPLC). Image analysis proved to be a promising technique to evaluate seed coating, in addition, samples treated with "on farm" technology had greater variation and heterogeneity in coating and active ingredient dose, while samples treated industrially showed greater homogeneity, uniformity, effectiveness of applied products. There was a strong positive correlation between coating with phytosanitary products and DAE in treated corn seeds, important parameters in the evaluation of the quality of the treatment.
ABSTRACT
Considering the first wave of the pandemic scenario and the necessary operation of policies and strategies that promote the population's self-care to mitigate the spread of the COVID-19 virus, we see here the actions taken in the official digital media of the federal public administration in the period from March to October 2020. To this end, we used the method of content analysis on all material advertised by the Ministry of Health on the platforms Twitter, Youtube, Facebook, Instagram, Spotify, Soundcloud, and official websites;ministry of health, pandemic hotsite, and health blog. With the analysis, we verified the prevalence of contents that privilege the illustration of the ministry's achievements, the 1. Self-promotion of the management itself, with 27.57% of the total publications, 2. Self-care promotion 18.87%, 3. Official data with 18.55%, 4. Daily news with 18.03%, 5. Technical communication for specialized audiences with 9.25%, and 6. Structural technical operation with 7.73%. With 3428 posts and 428,073,246 interactions evaluated, we saw self-care promotion content (18.87%) being suppressed by 81.13% of other aspects addressed by official government communication. In this way, we found that the absence of proper official communicative support at a level equivalent to the health demands presented in the pandemic that was established, leaves gaps in essential guidelines for the population, and even misinformation, which may have compromised the rigorous confrontation of the dissemination of the virus. © 2023, Centro Nacional de Informacion de Ciencias Medicas.

ABSTRACT
The last few years the number of Brazilian recovered meteorites has doubled due to an intensive outreach program on meteorites, which began in 2009 with "There is an ET in your backyard [1,2], followed by Geologando project, and with collaboration of fireball camera networks. The number of new recovered freshly meteorite in the last 12 years is: 6 recovered falls, 3 probably falls, added to many finds some not yet submmited to NomCom. Many strewnfields were already determined by the sky observation cameras, but without recoveries yet, due to tropical vegetation and no government efforts. In Brazil there is no financial support to researchers for travel or to buy meteorites. This situation leads to an unbalanced scenario between individual and scientific interests. Recently, a fallen meteorite in Santa Filomena (SF) caught the media's attention, even during the Covid-19 pandemic [3]. Almost instantly, collectors and foreign dealers arrived at the small city, alarming the local authorities regarding the existence of a legal commercialization. How there is not yet a law that regulates meteorite property rights, these space objects could be treated as a thing without a previous owner, called "res nullius" [4] The Brazilian Constitution allows the creation of laws, therefore deputies proposed two specific bill for meteorite property. One of them known by the number 4.471/2020, prays to keep meteorites found in Brazil in private hands, but allows the State to retain the pieces for a limited time, if there is interest in researching them. The other one, registered under number 4.529/2020, aims to create what is called Brazilian Scientific Heritage from Space. Under this project, all meteorites found in Brazil would be state property [5]. The Brazilian Society of Geology (SBG) created a working group to propose a law substitute for the bills, which guarantees that Brazilian meteorites be studied by Brazilian scientists and after that, released to the market. The law had not yet been voted on when the scientific society became aware that a new Brazilian meteorite, named Socorro, had been approved at MB 110. It happens to be the second Brazilian Martian meteorite and the first basaltic shergottite, reforcing the arguments, of some researches, whose deffends the need of a restrictive law in Brazil. To ensure the discontent of Brazilian scientists, four grams of Socorro meteorite was gently donated by the dealer Michael Farmer. Socorro has been analysed by optical microscopy, Electron Probe Micro-Analyzer, Raman Spectroscopy, X-ray Fluorescence Spectroscopy, Inductively coupled plasma mass spectrometry (ICP-MS), Time of flight-Mass spectrometry, Particle Induced X-Ray Emission and other techniques. Some of those laboratories are working with meteorites for the first time. This could be of few interest for the international meteorite community, but the engagement of new scientists in the study of meteorites in Brazil have been very producent.

ABSTRACT
Background: As a reaction to the COVID-19 pandemic, a nation-wide lockdown was enforced in Brazil in March 2020, cancer care was impacted, and cancer screening reduced. Therefore, an increase in cancer diagnoses at more advanced stages was expected. In this study, we extracted data from our nationwide real-world database to evaluate the impact of the COVID-19 pandemic on the stage at diagnosis of breast cancer (BC) cases. Methods: We explored curated electronic medical record data of female patients, over 18 years of age, diagnosed with BC and with established disease stage based on the AJCC 8th edition, who started treatment or follow-up in the Oncoclínicas (OC) between Jan 1, 2018, and Dec 31, 2021. The primary objective was to compare stage distribution at first visit during COVID- 19 pandemic (2020-2021) with a historical control cohort from a period prior to the pandemic (2018- 2019). We investigated stage distribution according to age at diagnosis and tumor ER/HER2 subtype in univariate models. Associations were considered significant if they had a minimum significance (P < 0.1 in Chi-square test). The historical numbers of patients with BC at OC make it possible to identify differences in the prevalence of stages in the order of 5% comparing pre and post pandemic periods with a statistical power greater than 80%. Results: We collected data for 11,752 patients with initial diagnosis of BC, with 6,492 patients belonging to the pandemic (2020-2021) and 5,260 patients to the pre-pandemic period (2018-2019). For both ER+/ HER2- and HER2+ tumors, there was a lower percentage of patients with early-stage (defined as stage I-II) in the years 2020-2021 vs 2018-2019 and a considerable increase in advanced-stage disease (defined as stage IV). For triple negative BC (TNBC), there was a significant higher percentage of patients with advanced-stage disease in the pandemic vs pre-pandemic period (table 1). Age over 50 years was associated with a greater risk of advanced stage at diagnosis after the onset of the pandemic, with an absolute increase of 7% (P twosided <0.01). Conclusions: We observed a substantial increase in cases of advanced-stage BC in OC institutions as a result of delays in BC diagnoses due to the COVID-19 pandemic. The impact appeared greater in older adults, potentially because of stricter confinement in this group.
ABSTRACT
The context of the pandemic we experienced, caused by COVID-19, implied the adoption of several measures, in an attempt to limit its dissemination. Among which, there is social isolation and the prohibition of visits to institutionalized elderly people. These measures favor the worsening or onset of mental illnesses in the elderly, including depression. As a way to reduce these consequences, video calls began to be made in the institutions so that users could see and talk to their family/friends. For the realization of video calls, the informal caregivers began to request the WhatsApp application, because it is currently the most used application in this context. This is how we get to the question of this study: Is the digital application WhatsApp adapted for the institutionalized elderly population? This study then aims to: to know the opinion of the elderly about WhatsApp;identify the advantages, obstacles, limitations pointed out by them about this application;reduce the infoexclusion among the elderly population;stimulate the creation/maintenance of digital social networks;decrease consequences of the isolation caused by COVID-19. The methodology adopted for this study was qualitative, being an Exploratory Case Study, based on descriptive logic. A non-probabilistic convenience sample was selected, composed of 5 subjects institutionalized in an institution of Idanha-a-Nova. For data collection, a characterization questionnaire was applied, and the participant was observed in the interaction with WhatsApp, during which the field notes and observation grid were registered and finally the Focus Group technique was used. It was concluded that the application and the equipment itself are not adapted to the institutionalized elderly belonging to this study, mainly due to the difficulty in accessing effectively, efficiently and satisfactorily. © 2021 AISTI.
ABSTRACT
Introduction: Standard precautions (SP) are measures recommended by the World Health Organization for infection control. There are widespread recommendations of security measures during the COVID-19 pandemic. Objectives: to investigate adherence of a nursing professionals regarding SP during the COVID-19 pandemic and to examine the association among length of experience, professionals with graduate degrees and workplace setting with the percentage of adherence. Methods: A pilot cross-sectional study was conducted using a validated questionnaire. Nursing professionals working in the front line of the COVID-19 pandemic in the State of São Paulo, Brazil, participated in the study. Data were analyzed using descriptive statistics and presented using absolute and relative frequency. Pearson's Chi-square test ( X2) was used to verify the association between length of experience (years working in nursing), completion of postgraduate studies (certification, master's and doctorate), workplace (public or private) of nursing professionals, and the percentage of total adherence to SP. Results: 169 nursing professionals were evaluated, being 49 (29%) aged between 18 and 24 years old, 44 (26%) with ≤ 1 year of experience in nursing, 81 (48%) with postgraduate studies, and 91 (53.8%) were employed in private health institutions. In terms of adherence to the SP, 157 (92.9%) performed hand hygiene in the intervals of care, with greater adherence after being in contact with biological material 165 (97.6%). The majority of the participants reported always using gloves. There was no adequate adherence to the use of safety glasses, hats, handling with sharps or the notification of accidents at work. Chi-square test did not reveal significant association among the conditions: length of experience, completion of graduate studies and workplace of nursing professionals, with the percentage of total adherence to SP ( X2 (1) = 0.033;p = 0.855), ( X2 (1) = 0.006;p = 0.940), ( X2 (2) = 1.031;p = 0.597), respectively. Conclusion: Nursing professionals' adherence to SP was found to be below the ideal recommendation. Length of experience, having an advanced degree or workplace setting did not influence adherence to SP.
ABSTRACT
Background: This study's aims are to assess the current evidence presented in the literature regarding the potential risks of COVID-19 infection among pregnant women and consequent fetal transmission.
ABSTRACT
Right after the Chinese example in conducting COVID-19 epidemic originated in Wuhan, the readiness to detect and respond by health authorities to local (sometimes global) epidemics has become central lately. Within the idea of health 4.0, information about the individual is essential in supporting public community health policies. This paper presents a proposal for an epidemiological surveillance system applied to arboviruses. Data mining techniques and Machine Learning (ML) are used to design mathematical models for detecting epidemics enhanced by Aedes Aegypti (vector for dengue, chikungunaya, yellow fever and zica). Based on data, it is proposed an adaptive manner to reach better stability on results. A Prove of Concept (PoC) is presented for dengue epidemics detection, a common endemic disease in the semiarid region of Brazil. © 2021 IEEE.
ABSTRACT
The present article's main aim is to use the decolonial thought that comes with the emergence of the Modernity / Coloniality, in order to understand how the process of expansion of Western Europe's territories in the Global South culminated over the centuries in the colonizing not only of bodies, but of flavors and minds of the ones who were forcefully dominated. Based on the reflections of decolonial author, such as Aníbal Quijano and Maria Lugones, this article discusses the rise of decolonial feminism and its importance for the personal development of the oppressed, who find themselves in the vicinity of society's obscurantism and their own individuality. Through this analysis - having labor relations as a reference - the present work concludes that oppresion is perpetuated against subjects in the post-colonial world, taking into consideration that this same oppresion is even more intense when the intersectionality of race and gender is taken into account. Therefore, we propose a brief normative analysis of domestic labour in Brazil, presenting a portrait of this labour market, concluding these subjects are still inevitably victmized by "the people" and the capital. Finally, this article presents one final reflection on the situation of domestic workers, taking into consideration the severity of the current Covid19 pandemic and its immediate consequences in this field. Finally, this research is based on academic works by authors in line with decolonial epistemological thinking as a way of contributing to a break with the eurocentric knowledge standard and recognizing the importance of the emergence of a new scientific proposal, which should complementarity and not exclusionnary. © 2020 Centro Universitario de Brasilia.
