Avaliação do Ensino de Empreendedorismo entre Estudantes Universitårios por meio do Perfil Empreendedor
Entrepreneurship is a socioeconomic phenomenon that has been valued for its influence on the growth and
development of regional and national economies. The main promoter of this phenomenon are entrepreneurs,
subjects endowed with multiple features that make up their profiles. They are dynamic and results oriented,
benefitting from the fruits of their own personal efforts. Entrepreneurial education is highlighted as one of the most
efficient ways to promote an entrepreneurial culture and train new entrepreneurs. However, some difficulty has
been observed in assessing the effectiveness of teaching and learning this subject. The objective of this study was
to analyze, by means of multivariate techniques, an instrument whose function is to measure the learning of
Entrepreneurship, verifying the change in entrepreneur profiles of 407 college students participating or not in an
entrepreneurial training process. The results showed that students who participated in Entrepreneurship
educational training activities showed significant changes in their entrepreneurial profiles. The main contributions
showed growth in the Self-realization, Planner, Innovative and Risks Assumed dimensions
A list of land plants of Parque Nacional do CaparaĂł, Brazil, highlights the presence of sampling gaps within this protected area
Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of âParque Nacional do CaparaĂłâ (PNC) was previously built using online databases and published on the website "CatĂĄlogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states
COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study
Background:
The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms.
Methods:
International, prospective observational study of 60â109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms.
Results:
âTypicalâ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (â€â18 years: 69, 48, 23; 85%), older adults (â„â70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each Pâ<â0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country.
Interpretation:
This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men
Aspectos clĂnicos da intoxicação experimental pelas favas de Stryphnodendron fissuratum (Leg. Mimosoideae) em caprinos Clinical aspects of the experimental poisoning by the pods of Stryphnodendron fissuratum (Leg. Mimosoideae) in goats
Com o objetivo de caracterizar o quadro clĂnico da intoxicação por Stryphnodendron fissuratum Mart. (Leg. Mimosoideae) em caprinos, administraram-se as favas dessa planta a oito caprinos, por via oral forçada em doses Ășnicas e a outros dois caprinos, em doses fracionadas. A menor dose que causou sinais clĂnicos e morte foi a de 10g/kg. Doses de 20g/kg e 40g/kg causaram sinais acentuados e doses Ășnicas de 5g/kg nĂŁo provocaram sinais. Doses fracionadas de 5g/kg durante quatro dias, totalizando 20g/kg provocaram sinais acentuados e morte. Em ambos os grupos, os primeiros sinais de intoxicação foram observados a partir do primeiro dia de experimento e a evolução variou de 4-25 dias. A doença caracterizou-se principalmente por alteraçÔes digestĂłrias e nervosas que consistiram em anorexia, desidratação, hipomotilidade e atonia ruminal, timpanismo, gemidos constantes, dor Ă percussĂŁo abdominal, fezes com muco, ranger de dentes, apatia, ataxia, dismetria, tremores de cabeça, tremores musculares, fraqueza com o andar cambaleante e trĂŽpego, acentuada depressĂŁo e decĂșbito esternal ou lateral prolongado e morte. Alguns animais apresentaram acentuada queda de pĂȘlos na regiĂŁo dorsal; apenas um caprino apresentou fezes lĂquidas, marrom-escuras e fĂ©tidas. Outros sinais incluĂram perda de fluido ruminal durante a ruminação, sialorrĂ©ia, exsudato nasal seroso e lacrimejamento. As provas de função hepĂĄtica e renal revelaram alteraçÔes discretas. As concentraçÔes sĂ©ricas de aspartato aminotransferase encontraram-se levemente aumentadas e as de creatinofosfocinase muito aumentadas.<br>In order to confirm the susceptibility of goats to the poisoning by Stryphnodendron fissuratum Mart. (Leg. Mimosoideae) and to characterize the clinical disease, the pods of the plant were given orally to each of eight young goats and in fractioned doses to other two. The lowest lethal dose was 10g/kg. The same dose was the lowest that induced disease. Doses of 20g/kg and 40g/kg caused pronounced clinical signs and doses of 5g/kg did not caused signs. Fractioned doses of 5g/kg during four days also caused pronounced signs. In each groups the first signs of poisoning were observed from the first day of experiments and the changes ranged from 4-25 days. The disease was characterized mainly by digestive and nervous disorders. Clinical signs were partial to complete anorexia, dehydration, decrease in ruminal activity up to atonia, tympanism, constant vocalizations, grinding of the teeth pain up on abdominal palpation, apathy, ataxia, depression, dysmetria, head and muscle tremors, weakness, difficulty in rising, sternal or lateral recumbency and death. Some goats presented extense hair loss in the skin of the dorsum; one goat presented liquid and black fetid feces. Other signs included loss of ruminal fluid during rumination, drooling, serous nasal and ocular discharges. Liver and kidney function tests had resulted in slight changes. AST serum levels were slightly increased and creatine phosphokinase levels were highly increased. These changes can associated to the effects of triterpenic saponins contained in the S. fissuratum pods

In-hospital mortality and severe outcomes after hospital discharge due to COVID-19: A prospective multicenter study from Brazil.
BackgroundWe evaluated in-hospital mortality and outcomes incidence after hospital discharge due to COVID-19 in a Brazilian multicenter cohort.MethodsThis prospective multicenter study (RECOVER-SUS, NCT04807699) included COVID-19 patients hospitalized in public tertiary hospitals in Brazil from June 2020 to March 2021. Clinical assessment and blood samples were performed at hospital admission, with post-hospital discharge remote visits. Hospitalized participants were followed-up until March 31, 2021. The outcomes were in-hospital mortality and incidence of rehospitalization or death after hospital discharge. Kaplan-Meier curves and Cox proportional-hazard models were performed.Findings1589 participants [54.5% male, age=62 (IQR 50-70) years; BMI=28.4 (IQR,24.9-32.9) Kg/mÂČ and 51.9% with diabetes] were included. A total of 429 individuals [27.0% (95%CI,24.8-29.2)] died during hospitalization (median time 14 (IQR,9-24) days). Older age [vs<40 years; age=60-69 years-aHR=1.89 (95%CI,1.08-3.32); age=70-79 years-aHR=2.52 (95%CI,1.42-4.45); ageâ„80-aHR=2.90 (95%CI 1.54-5.47)]; noninvasive or mechanical ventilation at admission [vs facial-mask or none; aHR=1.69 (95%CI 1.30-2.19)]; SAPS-III scoreâ„57 [vs<57; aHR=1.47 (95%CI 1.13-1.92)] and SOFA scoreâ„10 [vs <10; aHR=1.51 (95%CI 1.08-2.10)] were independently associated with in-hospital mortality. A total of 65 individuals [6.7% (95%CI 5.3-8.4)] had a rehospitalization or death [rate=323 (95%CI 250-417) per 1000 person-years] in a median time of 52 (range 1-280) days post-hospital discharge. Age â„ 60 years [vs <60, aHR=2.13 (95%CI 1.15-3.94)] and SAPS-III â„57 at admission [vs <57, aHR=2.37 (95%CI 1.22-4.59)] were independently associated with rehospitalization or death after hospital discharge.InterpretationHigh in-hospital mortality rates due to COVID-19 were observed and elderly people remained at high risk of rehospitalization and death after hospital discharge.FundingFundação Carlos Chagas Filho de Amparo Ă Pesquisa do Estado do Rio de Janeiro (FAPERJ), Conselho Nacional de Desenvolvimento CientĂfico e TecnolĂłgico (CNPq) and Programa INOVA-FIOCRUZ
