title: Association between rectus femoris cross-sectional area and diaphragmatic excursion with weaning of tracheostomized patients in the intensive care unit

description: ABSTRACT Objective: To verify the relationship between the rectus femoris cross-sectional area and diaphragmatic excursion with successful weaning from mechanical ventilation in chronic critically tracheostomized patients. Methods: This was a prospective observational cohort study. We included chronic critically ill patients (those who underwent tracheostomy placement after 10 days under mechanical ventilation). The rectus femoris cross-sectional area and diaphragmatic excursion were obtained by ultrasonography performed within the first 48 hours after tracheostomy. We measured rectus femoris cross-sectional area and diaphragmatic excursion to assess their association with weaning from mechanical ventilation, including their potential to predict successful weaning and survival throughout the intensive care unit stay. Results: Eighty-one patients were included. Forty-five patients (55%) were weaned from mechanical ventilation. The mortality rates were 42% and 61.7% in the intensive care unit and hospital, respectively. The fail group in relation to the success group at weaning presented a lower rectus femoris cross-sectional area (1.4 [0.8] versus 1.84 [0.76]cm2, p = 0.014) and lower diaphragmatic excursion (1.29 ± 0.62 versus 1.62 ± 0.51cm, p = 0.019). When rectus femoris cross-sectional area ≥ 1.80cm2 and diaphragmatic excursion ≥ 1.25cm was a combined condition, it had a strong association with successful weaning (adjusted OR = 20.81, 95%CI 2.38 - 182.28; p = 0.006) but not with intensive care unit survival (adjusted OR = 0.19, 95%CI 0.03 - 1.08; p = 0.061). Conclusion: Successful weaning from mechanical ventilation in chronic critically ill patients was associated with higher measurements of rectus femoris cross-sectional area and diaphragmatic excursion.

title: Lockup periods during lockdown periods in the context of Brazilian funds

description: ABSTRACT This article aimed to test the effect of lockup periods on the performance of Brazilian equity funds and multimarket funds, considering the period affected by the 2019 coronavirus disease (COVID-19). This study contributes to better understanding the effects of redemption restrictions imposed on quotaholders, a relevant subject considering the increase in the number of funds in Brazil. This effect is analyzed with particular focus on the period affected by the COVID-19 pandemic. The results of this study have implications for individual and professional investors and may also interest large families of Brazilian funds, given that the establishment of lockup periods forms part of a long-term decision. The research has the potential to impact planning in the fund industry, the financial planning of small and large investors, as well as the literature on the subject, motivating the undertaking of new research. The sample was composed of 17,417 Brazilian funds, 13,581 of which were multimarket funds and 3,836 were equity funds, covering the period from January of 2018 to December of 2021. Various subsamples were evaluated for robustness purposes. The hypotheses were tested using a difference-in-difference model operationalized through a panel. Fund performance was estimated every quarter based on the four-factor alpha. The main results of the study reveal that lockup periods were positively associated with fund performance. On the other hand, during the period negatively affected by COVID-19, funds with greater lockup periods did not record better performance than the other funds (considering in the comparison the performance of groups with a shorter lockup and that of the funds before the pandemic), a result that may advance the discussion on the effects of redemption restrictions.

title: Research agenda in graduate programs (stricto sensu) in the theme Health Education in the period of 2015-2019

description: ABSTRACT This study aimed to systematize the academic production related to the theme Health Education, developed in graduate programs from Brazil. For operational reasons, the four-year period 2015-2019 was chosen, by the same period in which Coordination for the Improvement of Higher Education Personnel evaluate the graduate programs. The systematization process was carried out between the months of August and December 2020, using the technique of integrative review in order to the inclusion and exclusion of documents concerning the objective of the study. The data indicate that the area of Education had a very low performance from the point of view of the production of thesis and dissertations, when compared to the areas of Nursing, for example. It is possible to indicate a distance from the area of Education in relation to the theme Health Education. It is concluded, therefore, that the focal theme of this study is weakly influenced and/or has a weak contribution from education, which can constitute an important deficit for the development of the theme Health Education in the Brazilian context.

title: Associated Factors with Congenital Heart Disease in the Most Populated State of Brazil Between 2010 and 2018

description: Abstract Background Cardiac anomalies are the most prevalent congenital malformations among live births in the world. In Brazil, it is estimated that nearly 25,757 new cases occur each year, and the Southeast region presents the highest prevalence, with 10 new cases/1,000 live births. Objective The aim of this study is to evaluate the epidemiology of congenital heart disease (CHD) in the state of São Paulo. Methods This is a cross-sectional and time-series observational study with data from the Brazilian Information System on Live Births. Heart-related cardiac malformation cases — International Classification of Diseases (ICD) 10th revision Q20.0 to Q24.9 — were selected from January 2010 to December 2018, in the state of São Paulo, Brazil. This study analyzed rates of malformations per year and investigated associated factors, using single and multiple logistic regression models. The significance level adopted in this study was 5%. Results The highest cardiac malformation rate was in the São Paulo metropolitan region (2.84:1000), while the lowest was found in the region of Franca (0.3:1000). The most frequent defect was interatrial communication (38.2%). The main associated factors observed in this study were prematurity of 22 to 27 weeks (OR=4,401 95% CI: 3,796-5,104) — CI: Confidence Interval; OR: Odds ratio —, mother’s age between 35 and 49 years of age (OR=1,602 95% CI: 1,525-1,682), yellow race (OR=1,481 95% CI: 1,235-1,775), triple or more pregnancy (OR=1,438 95% CI: 1,004-2,060), and history of a dead child (OR=1,213 95% CI: 1,152-1,277). Conclusion The main factors associated with this outcome, which are part of the obstetric history of mothers, should be addressed and considered when pregnancy is a planned event.

title: Growth and physiology of ‘Sunrise’ papaya seedlings in response to salinity and humic acid

description: ABSTRACT Salinity is one of the major obstacles to agriculture in semi-arid regions, as it affects the physiological processes, growth, and yield of numerous crops. Hence, the application of salt stress attenuators is of paramount importance, as it enables the use of saline water for agricultural purposes. Among these, humic acid promotes the growth as well as water and nutrient uptake of plants. To this end, the present study evaluated the effects of humic acid on the growth and physiology of Carica papaya seedlings irrigated with saline water. The experiment followed the randomized block design with five levels of electrical conductivity (0.5, 1.15, 2.75, 4.35, and 5.0 dS m-1) and five concentrations of humic acid (0.5, 0.94, 2.0, 3.06, and 3.5 mL L-1). Growth, gas exchange, chlorophyll content, and chlorophyll a fluorescence were evaluated. Irrigation with 4.9 dS m-1 water and application of 3.05 mL L-1 humic acid promoted the growth of papaya seedlings. Irrigation with high-salinity water (4.96 and 3.09 dS m-1) coupled with the application of 3.05 and 2.21 mL L-1 humic acid increased internal CO2 concentration, transpiration, instantaneous water use efficiency, carboxylation efficiency, and chlorophyll b content. Overall, humic acid (3.5 mL L-1) attenuated the deleterious effects of salt stress, promoting the growth and improving the performance of papaya seedlings under moderate salinity (4 dS m-1).

title: Gas exchange and photochemical efficiency of guava under saline water irrigation and nitrogen-potassium fertilization

description: ABSTRACT The objective of this study was to evaluate the effects of different combinations of nitrogen and potassium fertilization on gas exchange and chlorophyll a fluorescence in seedlings of guava cv. Paluma irrigated with water of different salinity levels. The experiment was set up in a randomized block design and analyzed in 5 × 4 factorial scheme, with four replicates. The treatments were composed of the combination of the factor electrical conductivity of irrigation water - ECw (0.3, 1.1, 1.9, 2.7, and 3.5 dS m-1), with the factor combinations (C) formed from recommended doses of nitrogen (N) and potassium (K2O), 70% N + 50% K2O, 100% N + 75% K2O, 130% N + 100% K2O, and 160% N + 125% K2O. The fertilization combination 130% N + 100% K2O mitigated the effects of salt stress up to mean ECw of 1.3 dS m-1, resulting in increments in CO2 assimilation rate, transpiration, instantaneous carboxylation efficiency, and electron transport rate. For maximum quantum efficiency of photosystem II, only treatment irrigated with ECw 3.5 dS m-1 under the combination 160% N + 125% K2O showed damage to the photosynthetic apparatus.

title: What changed between the peak and plateau periods of the first COVID-19 pandemic wave? A multicentric Portuguese cohort study in intensive care

description: ABSTRACT Objective: To analyze and compare COVID-19 patient characteristics, clinical management and outcomes between the peak and plateau periods of the first pandemic wave in Portugal. Methods: This was a multicentric ambispective cohort study including consecutive severe COVID-19 patients between March and August 2020 from 16 Portuguese intensive care units. The peak and plateau periods, respectively, weeks 10 - 16 and 17 - 34, were defined. Results: Five hundred forty-one adult patients with a median age of 65 [57 - 74] years, mostly male (71.2%), were included. There were no significant differences in median age (p = 0.3), Simplified Acute Physiology Score II (40 versus 39; p = 0.8), partial arterial oxygen pressure/fraction of inspired oxygen ratio (139 versus 136; p = 0.6), antibiotic therapy (57% versus 64%; p = 0.2) at admission, or 28-day mortality (24.4% versus 22.8%; p = 0.7) between the peak and plateau periods. During the peak period, patients had fewer comorbidities (1 [0 - 3] versus 2 [0 - 5]; p = 0.002) and presented a higher use of vasopressors (47% versus 36%; p &lt; 0.001) and invasive mechanical ventilation (58.1 versus 49.2%; p &lt; 0.001) at admission, prone positioning (45% versus 36%; p = 0.04), and hydroxychloroquine (59% versus 10%; p &lt; 0.001) and lopinavir/ritonavir (41% versus 10%; p &lt; 0.001) prescriptions. However, a greater use of high-flow nasal cannulas (5% versus 16%, p &lt; 0.001) on admission, remdesivir (0.3% versus 15%; p &lt; 0.001) and corticosteroid (29% versus 52%, p &lt; 0.001) therapy, and a shorter ICU length of stay (12 days versus 8, p &lt; 0.001) were observed during the plateau. Conclusion: There were significant changes in patient comorbidities, intensive care unit therapies and length of stay between the peak and plateau periods of the first COVID-19 wave.
