title: Telework in health: where are we heading to?

description: ABSTRACT OBJECTIVE To identify the legal norms published in 2020 and 2021 aimed at directly or indirectly regulating telework in health in Brazil, focusing on these contexts: workday length; ergonomics; work environment; worker safety and health. METHODS Legislative and documentary research, with a descriptive qualitative approach. We collected and selected all legal norms dealing directly or indirectly with the regulation of telework in health in Brazil, published in the bases of the National Press and Health Professional Councils until June 2021. RESULTS Until June 2021, there were 113 valid legal norms on the regulation of telework in health, and more than half of them (64) were published in 2020. We identified only a few norms aimed at regulating or guiding aspects related to workday length; ergonomics; work environment; and worker safety and health. From the 113 norms, only one deals with workday length and just 13 pointed out the importance of working environments for offering a good service. DISCUSSION We identified that the selected legal norms lack of devices which regulate telework in health, failing to defend workers’ and patients’ rights, or to guarantee favorable remote work conditions, whether at home or somewhere else.

title: Brazilian inflation and the Theory of Games

description: ABSTRACT Based on the disaggregation of the private sector as an amplification of the well-known Barro & Gordon policy-game model, a coordination and/or cooperation problem of the price-setters in the private sector is identified as a possible cause for the persistence of inflation even during stabilization efforts. This kind of persistence is, at least in the short-term, independent from the willingness of the government to stop inflation. A process of self-fulfilling prophecies is started by the “wait-and-see” behavior of private sector’s price-setters, which can result in the giving up of the stabilization policy. Breaking this “wait-and-see” behavior could be one of the major problems in stabilizing economies with chronic high inflation.

title: Fatty Acid Content and Physicalchemical Properties of Cagaite Seed Oil (Eugenia dysenterica DC) Obtained by Different Extraction Methods

description: Cagaiteira, the fruit popularly known as cagaite, belongs to the Myrtaceae family. Seed oil cagaite (Eugenia dysenterica DC) was obtained by three methods of extraction, extraction using an ultrasound (OCU), extraction by mechanical pressing (OCP) and extraction with Soxhlet extractor (OCS) in 3 different times (3, 6 and 9 h) and the content of fatty acids and physicalchemical properties were compared. The rate of saturated fatty acids ranged from 19.46% (OCP03) to 31.18% (OCS09), while the amount of unsaturated fatty acids ranged from 54.72% (OCP03) to 67.64% (OCS09). Linoleic and linolenic acids, important in nutrition food, varied between 32.22-38.11 and 5.55-8.78%, respectively. For oxidative stability, OCUAq (heated ultrasound extraction) samples showed the highest induction periods, showing a positive correlation with antioxidant activity and phenol content, demonstrating the efficiency of the use of ultrasonic extraction to obtain quality oils from cagaite seeds.

title: Stem growth of Amazonian species is driven by intra-annual variability in rainfall, vapor pressure and evapotranspiration

description: ABSTRACT Intra-annual distribution of precipitation in central Amazonia often leads to a short mild dry season and an increase in irradiance, temperature, and vapor pressure deficit; however, the accurate effect of intra-annual microclimatic variability on stem growth is still under investigation. The objective of this study was to determine how stem growth responds to monthly variations in microclimatic factors in the central Amazon. During five years (2008-2012) we measured diameter stem growth of 109 trees (26 species) and used principal component regression to evaluate the effect of microclimatic variability on stem growth in diameter. We found that the mean stem growth in diameter across species increased in response to an increase in rainfall and reference evapotranspiration, but it decreased with a rise in mean and minimum vapor pressure deficit. A contribution of this study is to show that even when irradiance and temperature had no significant effect on stem growth, small changes in vapor pressure deficit significantly affect stem growth. If the dry season becomes longer, as predicted by models, trees currently more sensitive to microclimatic variability associated with droughts would be the most affected by climate changes.

title: Cardiac Hydatid Cyst: An Uncommon Cause of Complete Atrioventricular Block

description: Abstract Hydatidosis is a zoonosis caused by Echinococcus granulosus, leading to the formation of cysts on involved organs. Cardiac involvement is rare and can cause a wide range of complications secondary to rupture, embolization, or compression. Its diagnosis is challenging, and is generally confirmed through data related to clinical manifestations, environmental exposure, and laboratory and imaging exams. Surgical removal is necessary in most cases, in which an association with antiparasite therapy is recommended. The present article describes a case of a cardiac hydatid cyst associated with a complete atrioventricular block (AVB) in a young adult patient, with the need for a pacemaker implant, an atypical presentation, and scarce reports in the literature.

title: Covid-19 hospital mortality using spatial hierarchical models: cohort design with 74,994 registers

description: ABSTRACT OBJECTIVE To investigate the relationship between covid-19 hospital mortality and risk factors, innovating by considering contextual and individual factors and spatial dependency and using data from the city of São Paulo, Brazil. METHODS The study was performed with a spatial hierarchical retrospective cohort design using secondary data (individuals and contextual data) from hospitalized patients and their geographic unit residences. The study period corresponded to the first year of the pandemic, from February 25, 2020 to February 24, 2021. Mortality was modeled with the Bayesian context, Bernoulli probability distribution, and the integrated nested Laplace approximations. The demographic, distal, medial, and proximal covariates were considered. RESULTS We found that per capita income, a contextual covariate, was a protective factor (odds ratio: 0.76 [95% credible interval: 0.74–0.78]). After adjusting for income, the other adjustments revealed no differences in spatial dependence. Without income inequality in São Paulo, the spatial risk of death would be close to one in the city. Other factors associated with high covid-19 hospital mortality were male sex, advanced age, comorbidities, ventilation, treatment in public healthcare settings, and experiencing the first covid-19 symptoms between January 24 and February 24, 2021. CONCLUSIONS Other than sex and age differences, geographic income inequality was the main factor responsible for the spatial differences in the risk of covid-19 hospital mortality. Investing in public policies to reduce socioeconomic inequities, infection prevention, and other intersectoral measures should focus on lower per capita income, to control covid-19 hospital mortality.

title: Seroprevalence of SARS-CoV-2 antibodies in schoolchildren in the city of São Paulo, 2020

description: ABSTRACT OBJECTIVE To estimate seroprevalence of SARS-CoV-2 antibodies in schoolchildren aged 4 to 14 years living in the city of São Paulo, according to clinical, demographic, epidemiological, and social variables, during the school closure period as a measure against covid-19 spread. METHODS A serological survey was made in September 2020 with a random sample stratified by school system (municipal public, state public and private) type. A venous blood sample was collected using the Wondfo SARS-CoV-2 Antibody Test (lateral flow method) for detection of total SARS-CoV-2 virus antibodies. Semi-structured questionnaires were applied to collect clinical, demographic, social, and epidemiological data. RESULTS Seroprevalence of SARS-CoV-2 antibodies in schoolchildren was of 16.6% (95%CI 15.4–17.8). The study found higher seroprevalence in the municipal (18.5%; 95%CI 16.6–20.6) and state (16.2%; 95%CI 14.4–18.2) public school systems compared to the private school system (11.7; 95%CI 10.0–13.7), among black and brown students (18.4%; 95%CI 16.8–20.2) and in the most vulnerable social stratum (18.5 %;95%CI 16.9–20.2). Lower seroprevalence was identified in schoolchildren who reported following the recommended protective measures against covid-19. CONCLUSION Seroprevalence of SARS-CoV-2 antibodies is found mainly in the most socially vulnerable schoolchildren. This study can contribute to support public policies that reinforce the importance of suspending face-to-face classes and developing strategies aimed at protective measures and monitoring of the serological status of those who have not yet been included in the vaccination schedule.

title: Economic transition in Poland: the relevance of the Latin-American experience

description: ABSTRACT Shock therapy was used in Poland causing many problems. It is true that four years later the economy started to grow again, but the transition to the market economy took place with high unemployment rates and increasing social inequalities. Poland’s liberalization and economic stabilization program has a lot to do with similar programs experienced in Latin America and could be useful to Poland. In the short term, costs are similar to those of the Latin American experience. Even though stabilization was partially achieved, the social costs that took off were large, making the continuation of economic reform politically indigestible in the democratic context.

title: Invasive Versus Conservative Management of NSTEMI Patients Aged ≥ 75 Years

description: Abstract Background The efficiency of invasive management in older patients (≥75 years) with non-ST-segment elevation myocardial infarction (NSTEMI) remains ambiguous. Objectives To assess the efficiency of invasive management in older patients with NSTEMI based on meta-analysis and trial sequential analysis (TSA). Methods Relevant randomized controlled trials (RCT) and observational studies were included. The primary outcomes were all-cause death, myocardial infarction, stroke, and major bleeding. Pooled odd ratio (OR) and 95% confidence interval (CI) were calculated. P &lt;0.05 was considered statistically significant. Results Five RCTs and 22 observational studies with 1017374 patients were included. Based on RCT and TSA results, invasive management was associated with lower risks of myocardial infarction (OR: 0.51; 95% CI: 0.40-0.65; I2=0%), major adverse cardiovascular events (MACE; OR: 0.61; 95% CI: 0.49-0.77; I2=27.0%), and revascularization (OR: 0.29; 95% CI: 0.15-0.55; I2=5.3%) compared with conservative management. Pooling results from RCTs and observational studies with multivariable adjustment showed consistently lower risks of all-cause death (OR: 0.57; 95% CI: 0.50-0.64; I2=86.4%), myocardial infarction (OR: 0.63; 95% CI: 0.56-0.71; I2=0%), stroke (OR: 0.59; 95% CI: 0.51-0.69; I2=0%), and MACE (OR: 0.64; 95% CI: 0.54-0.76; I2=43.4%). The better prognosis associated with invasive management was also observed in real-world scenarios. However, for patients aged ≥85 years, invasive management may increase the risk of major bleeding (OR: 2.68; 95% CI: 1.12-6.42; I2=0%). Conclusions Invasive management was associated with lower risks of myocardial infarction, MACE, and revascularization in older patients with NSTEMI, yet it may increase the risk of major bleeding in patients aged ≥85 years.
