Short-term add-on therapy with angiotensin receptor blocker for end-stage inotrope-dependent heart failure patients: B-type natriuretic peptide reduction in a randomized clinical trial
OBJECTIVE: We aimed to evaluate angiotensin receptor blocker add-on therapy in patients with low cardiac output during decompensated heart failure. METHODS: We selected patients with decompensated heart failure, low cardiac output, dobutamine dependence, and an ejection fractio
Necessidades de irrigação suplementar em soja nas condições edafoclimáticas do Planalto Médio e Missões, RS.
Este trabalho foi conduzido com a finalidade de estimar as necessidades estocásticas de irrigação suplementar por aspersão na cultura da soja (Glycine max L. Merrill), nas regiões agroecológicas do Estado do Rio Grande do Sul, denominadas de Planalto Médio e Missões. As necessidades foram simuladas em relação à combinação entre locais, épocas de semeadura, níveis de manejo da irrigação e entre níveis de ocorrência . As necessidades de irrigação suplementar foram máximas na semeadura de 15 de outubro, e os menores valores foram encontrados na semeadura de 15 de dezembro; as necessidades de irrigação suplementar foram maiores nas condições agroecológicas das Missões quando comparadas com as do Planalto Médio; as lâminas de irrigação suplementar estimadas aumentaram à medida que o nível de risco diminuiu
Area spectrum and quasinormal modes of black holes
We demonstrate that an equidistant area spectrum for the link variables in
loop quantum gravity can reproduce both the thermodynamics and the quasinormal
mode properties of black holes.Comment: 11 pages, no figures; references adde

Simulating maize yield in sub-tropical conditions of southern Brazil using Glam model
The objective of this work was to evaluate the feasibility of simulating maize yield in a sub‑tropical
region of southern Brazil using the general large area model (Glam). A 16‑year time series of daily weather data
were used. The model was adjusted and tested as an alternative for simulating maize yield at small and large
spatial scales. Simulated and observed grain yields were highly correlated (r above 0.8; p<0.01) at large scales
(greater than 100,000 km2), with variable and mostly lower correlations (r from 0.65 to 0.87; p<0.1) at small
spatial scales (lower than 10,000 km2). Large area models can contribute to monitoring or forecasting regional
patterns of variability in maize production in the region, providing a basis for agricultural decision making, and
Glam‑Maize is one of the alternatives
Emotional, hyperactivity and inattention problems in adolescents with immunocompromising chronic diseases during the COVID-19 pandemic
Objective: To assess factors associated with emotional changes and Hyperactivity/Inattention (HI) motivated by COVID-19 quarantine in adolescents with immunocompromising diseases.
Methods: A cross-sectional study included 343 adolescents with immunocompromising diseases and 108 healthy adolescents. Online questionnaires were answered including socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and validated surveys: Strengths and Difficulties Questionnaire (SDQ), Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0).
Results: The frequencies of abnormal emotional SDQ scores from adolescents with chronic diseases were similar to those of healthy subjects (110/343 [32%] vs. 38/108 [35%], p = 0.548), as well as abnormal hyperactivity/inattention SDQ scores (79/343 [23%] vs. 29/108 [27%], p = 0.417). Logistic regression analysis of independent variables associated with abnormal emotional scores from adolescents with chronic diseases showed: female sex (Odds Ratio [OR = 3.76]; 95% Confidence Interval (95% CI) 2.00‒7.05; p < 0.001), poor sleep quality (OR = 2.05; 95% CI 1.08‒3.88; p = 0.028) and intrafamilial violence during pandemic (OR = 2.17; 95% CI 1.12‒4.19; p = 0.021) as independently associated with abnormal emotional scores, whereas total PedsQL score was inversely associated with abnormal emotional scores (OR = 0.95; 95% CI 0.93‒0.96; p < 0.0001). Logistic regression analysis associated with abnormal HI scores from patients evidenced that total PedsQL score (OR = 0.97; 95% CI 0.95‒0.99; p = 0.010], changes in medical appointments during the pandemic (OR = 0.39; 95% CI 0.19-0.79; p = 0.021), and reliable COVID-19 information (OR = 0.35; 95% CI 0.16‒0.77; p = 0.026) remained inversely associated with abnormal HI scores.
Conclusion: The present study showed emotional and HI disturbances in adolescents with chronic immunosuppressive diseases during the COVID-19 pandemic. It reinforces the need to promptly implement a longitudinal program to protect the mental health of adolescents with and without chronic illnesses during future pandemics
