title: Medical students in the Covid-19 pandemic: experiences through narratives

description: Abstract: Introduction: The pandemic caused by the new coronavirus (Sars-cov-2) has resulted in economic, social and mental health consequences for individuals with the establishment of social distancing. Consequently, medical schools suspended their activities, with the need to rethink the structure of academic education, affecting students in the fifth and sixth years with greater intensity. Objective: To understand the emotional, social and academic and professional training consequences of social distancing resulting from the COVID-19 pandemic, from the perspective of the medical student in the last two years of medical school, after the interruption of in-person activities. Method: Study conducted at a medical school in the interior of São Paulo, with students from the last two years of the medical course. This is a qualitative field research, carried out through narratives with thematic content analysis, according to Bardin and Minayo. Results: Eleven narratives were analyzed, seven written by fifth-year students and four by sixth-year students. In them, fear of the pandemic and its consequences, disbelief with the country’s situation and criticism of the behavior of acquaintances were evident. In the academic setting, there was concern about the interruption of practical activities close to the end of the undergraduate course, thoughts about being a medical student on clinical clerkship during the pandemic, with a feeling of incapacity in helping to cope with the health crisis, as well as fear of getting infected or infecting family members. However, the need for rest, reinforcement of family bonds and opportunities for new learning were also reported. Conclusions: In short, the pandemic generated concerns about uncertainties in the social, economic, political and scientific fields, which, added to the moment of these medical students’ education, contributed to difficulties in relation to mental health. However, the period was also evaluated as a positive one, as it provided free time to increase study performance, in addition to the opportunity to carry out extracurricular activities.

title: Support capacity of a floodplain lake for intensive fish production (Rondônia, Brazil)

description: Abstract The Amazon Basin stands out mainly for its large floodplain’s areas, which during the period of high water become important environments for the maintenance of the life cycle of many fish species. These floodplains act as a source of food and an area for growth and reproduction for the fish assemblages. However, there are few studies on the use of floodplain lakes for breeding fish in confinement. Therefore, we analyzed the support capacity and environmental parameters of Lake Cujubim, in the Madeira River Basin, regarding its use for the implementation of intensive fish farming (net tank system). From 2019 to 2020, bathymetric profiles and limnological data were collected, considering the seasonality of the water level and the shape of the Lake Cujubim. The bathymetry data were primarily used to verify the parameters of depth, area and volume of the lake, while limnological data contributed to statistical analyses for the evaluation of health status and support capacity of the lake for fish farming in an intensive production system. The data collected from the limnological analyses and the depth and profile indicate that Lake Cujubim is suitable for the cultivation of fish, and has an estimated support capacity for an annual production of up to 468.31 tonnes of fish. Herein, we propose a viable alternative for the social and productive development of intensive fish farming in an area of floodplain lake in the state of Rondônia, Brazil.

title: Perceived stress and associated factors in pregnant women: a cross-sectional study nested within a population-based cohort

description: Abstract Objectives: to estimate the prevalence of perceived stress and verify the associated factors in pregnant women assisted by Family Health teams in Montes Claros, Minas Gerais - Brazil. Methods: epidemiological, cross-sectional, and analytical study, nested in a population-based cohort. Sociodemographic and obstetric characteristics and physical and mental health conditions were assessed. The stress level was estimated by the Perceived Stress Scale (PSS-14). Descriptive and bivariate analyses were conducted, followed by the Poisson Regression model with robust variance. Results: a total of 1,279 pregnant women participated. The prevalence of high-stress levels was 23.5% (CI95%=20.8%-26.2%). The outcome was more prevalent among pregnant women aged above 35 years (PR=1.38; CI95%=1.09-1.74) and less than or equal to 19 (PR=1.41; CI95%=1.13-1.77); without a partner (PR=1.33; CI95%=1.09-1.62); with low social support (PR=1.42; CI95%=1.18-1.70); multiparous (PR=1.30; CI95%=1.02-1.66); with current unplanned pregnancy (PR=1.23; CI95%=1.00-1.52); urinary tract infection (PR=1.35; CI95%=1.12-1.62); high level of anxiety symptoms (PR=1.42; CI95%=1.18-1.71); severe (PR=4.74; CI95%=3.60-6.26) and moderate (PR=3.19; CI95%=2.31-4.39) symptoms of depression; and neurological complaints (PR=1.77; CI95%=1.27-2.47). Conclusions: there was a significant prevalence of high perceived stress among pregnant women, an outcome associated with sociodemographic, clinical, obstetric, and emotional factors, which demonstrates the need for comprehensive care of pregnant women’s health.

title: Long-term resveratrol administration improves diabetes-induced pancreatic oxidative stress, inflammatory status, and β cell function in male rats

description: Abstract Diabetes is a metabolic disorder caused by insulin resistance or a defect in the pancreatic beta cells in insulin secretion. The aim of this study was to evaluate the possible effectiveness of long-term administration of resveratrol on inflammatory and oxidative stress markers in the pancreatic tissue of diabetic rats. Male Wistar rats (n = 24) were randomly divided into four groups of six animals, namely a healthy group, a healthy group receiving resveratrol, a diabetic control group, and a diabetic group receiving resveratrol. Diabetes was induced by single dose injection of streptozotocin (50 mg/kg; ip), 15 min after injection of nicotinamide (110 mg/kg; ip). Resveratrol was also administered by gavage (5 mg/kg/day) for 4 months. Administration of resveratrol alleviated hyperglycemia, weight loss and pancreatic β cell function measured by HOMA-β. Resveratrol improved oxidative stress (nitrate/nitrite, 8-isoprostane and glutathione) and proinflammatory markers (tumor necrosis factor α, cyclooxygenase 2, interleukin 6 and nuclear factor kappa B) in the pancreatic tissue of diabetic rats. Resveratrol administration had no significant effect on the activity of superoxide dismutase and catalase enzyme. These observations indicate that resveratrol administration may be effective as a beneficial factor in improving pancreatic function and reducing the complications of diabetes.

title: ARTICLE - WHAT IS THE VALUE OF A QUALITY EARLY CHILDHOOD EDUCATION?

description: ABSTRACT: This study aims to problematize how the future evaluation of K-12 educational offers and reflects on the guidelines that may ground quality parameters for childhood education after the determinations of the new Fundeb. We analyzed data from the School Census of K-12 Education done by Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (Inep) and the Demographic Census of IBGE. Based on this data, we discuss how far the wishful thinking of childhood education lies. We show that children’s access to kindergarten and preschool needs to be more equitable, public investment needs to be guided towards public systems, and allocating resources is a key mechanism to reducing inequality. Finally, our findings point out the need to reinforce the concept of Custo Aluno Qualidade (CAQ- Student Quality Cost), sizing the necessary input to scale the access of all children to a quality childhood education.

title: Effect of antenatal class attendance on fear of childbirth and antenatal stress

description: ABSTRACT OBJECTIVE To assess the effect of attending antenatal classes on fear of childbirth and antenatal stress in nulliparous pregnant women. METHODS A total of 133 nulliparous pregnant women participated in the study, which had a quasi-experimental design. Data were collected by a descriptive data form, the Wijma Delivery Expectancy/Experience Questionnaire, and the Antenatal Perceived Stress Inventory (APSI). RESULTS A significant correlation was found between antenatal class attendance and having a high schooling level and an intended pregnancy (p &lt; 0.05). The mean fear of childbirth score of pregnant women was 85.50 ± 19.41 before the training and 76.32 ± 20.52 after the training, and the difference between these scores was significant (p &lt; 0.01). Fear of childbirth score were not significantly different between the intervention group and the control group. The mean APSI score of pregnant women in the intervention group was 22.32 ± 6.12 before the training and 21.79 ± 5.97 after the training. However, this difference was not statistically significant (p = 0.70). CONCLUSION The fear of childbirth score decreased significantly in the intervention group after the training.

title: Smoking cessation for peripheral arterial disease: systematic review protocol

description: ABSTRACT Background: peripheral arterial disease has smoking as its main avoidable vascular risk factor. However, most studies do not focus on smoking as the main exposure variable. Objectives: to assess the impact of smoking cessation interventions versus active comparator, placebo or no intervention, on peripheral arterial disease outcomes. Methods: we will use the Cochrane Handbook for Systematic Reviews of Interventions to guide whole this review process. We will consider parallel or cluster-randomised controlled trials (RCTs), quasi-RCTs, and cohort studies. We will search CENTRAL, MEDLINE, Embase, PsycINFO, LILACS and IBECS. We will also conduct a search of ClinicalTrials.gov and the ICTRP for ongoing or unpublished trials. Each research step will involve at least two independent reviewers. We will create a table, using GRADE pro GDT software, reporting the pooled effect estimates for the following outcomes: all-cause mortality, lower limb amputation, adverse events, walking distance, clinical severity, vessel or graft secondary patency, and QoL. Conclusions: we will assess these outcomes according to the five GRADE considerations to assess the certainty of the body of evidence for these outcomes, and to draw conclusions about the certainty of the evidence within the review.

title: International Entrepreneurship: Thematic Mapping and Research Agenda Proposal

description: Abstract This study aimed to carry out a bibliometric analysis of the production on International Entrepreneurship IE based on perspectives of the thematic structure of the field using thematic mapping techniques to model the knowledge produced in it. Data from the scientific production on the subject were collected from Scopus and Web of Science databases. Three thematic maps representing the periods of 1995-2004, 2005-2014 and 2015-2022 were yielded in the study. The discussion of results concludes that IE is a research area that has grown significantly since the second period, showing a considerable increase in publications from 127 in the first period to 1,042 in the second. This increase remained constant reaching 1,934 in the third and final period. The themes that stood out the most and were most representative in the field of IE were: performance of companies in IE, innovation, knowledge, entrepreneurial companies, entrepreneurial orientation, management, strategy, model and export behavior. A conceptual variation of the themes was also observed with the performance theme standing out, maintaining a high representativeness in the three periods analyzed with displacements between the basic themes – transversal – and the driving themes. Another highlight was the capabilities theme, which, over time, resulted in the dynamic capabilities theme. As emerging themes, performance, entrepreneurial orientation, entrepreneurship, impact and management appear. Based on the results and conclusions of this study, a research agenda is proposed.
