RESUMO Objetivo: Selecionar os indicadores dos Objetivos do Desenvolvimento Sustentável (ODS) determinantes da desnutrição infantil (DI) no Brasil e monitorar o alcance das metas da DI, por região, no ano de 2022. Métodos: Estudo ecológico que utilizou os índices do Desenvolvimento Sustentável no Brasil e analisou os 100 indicadores de monitoramento dos ODS nos 5.570 municípios brasileiros. Foi construída uma árvore de classificação e regressão e calculada a sensibilidade para predizer os determinantes da DI. O teste qui-quadrado foi utilizado, e adotado nível de significância de 5%. As análises descritivas e a árvore foram realizadas com o auxílio do software R. Resultados: Os determinantes da DI segundo percentuais, regiões do país mais afetadas e ordem de impacto foram: analfabetismo na população com ≥15 anos (Nordeste), pré-natal insuficiente (Norte), baixo peso ao nascer (Sul), mulheres jovens de 15 a 24 anos de idade que não estudam nem trabalham (Norte e Nordeste) e população ocupada entre 10 e 17 anos (Sul). Observou-se efeito individual e cumulativo na prevalência de DI nos municípios brasileiros, variando de 1,73 a 15,1%, de acordo com a ocorrência e sobreposição desses indicadores. Conclusão: Os dados indicam que o Brasil não atingirá a meta de redução da DI estabelecida até o ano de 2025. Serão necessários mais investimentos nas áreas da educação e saúde, voltados principalmente para o público materno infantil e nas regiões Norte e Nordeste.

ABSTRACT Objective: To select indicators of the Sustainable Development Goals (SDGs) that determine child malnutrition (CM) in Brazil and to monitor the achievement of SDG targets by region in 2022. Methods: This is a cross-sectional, ecological study that used the Brazilian Sustainable Development indices and analyzed the 100 SDG monitoring indicators in the 5,570 Brazilian municipalities. A decision tree was created and sensitivity analysis was performed to predict CM determinants. Data were analyzed using the χ2 test at 5% significance level. Descriptive analyses and the decision tree were carried out using the R software. Results: The CM determinants according to percentage, most affected regions of the country, and impact order were: illiteracy in the population aged ≥15 years (Northeast), insufficient prenatal care (North), low birth weight (South), young women aged 15-24 years who neither study nor work (North and Northeast), and employed population aged 10-17 years (South). We observed an individual and cumulative effect on the CM prevalence, ranging from 1.73 to 15.1%, in Brazilian municipalities according to the occurrence and overlap of these indicators. Conclusion: The results denote that Brazil will not achieve the intended reduction of CM by 2025. There must be substantial investments in education and health mainly aimed at the maternal and child population and especially in the North and Northeast regions.

Abstract The number of isotopic studies on Quaternary megafauna has increased over the last decades, yet, there is no published data addressing the status of scientific production of this research field. The present study shows the results of a bibliometric research carried out in the Scopus database where the publishing trends within this scientific field was analyzed using the open source software tool SciMAT. We retrieved 278 papers published from 1980 to 2019 and observed that a significant increase in publishing has mainly occurred in the last decade analyzed here. We also identified some of the field´s most influential articles and journals; recognized that carbon, oxygen and nitrogen isotopes are the most used markers in these studies; and that the most cited taxa are representatives of Equidae, Bovidae and Proboscidae. Also, Paleoecology is the basic thematic area, whereas Climate and Paleoenvironmental Changes is the one with the greatest development potential. Our results clearly show that the isotopic study on Quaternary megafauna is still under development and that some subjects could be further explored, such as analyzing more taxa within Carnivora, Pilosa, Notoungulata, Cetartiodactyla and Perissodactyla as well as using other less frequent stable isotope markers, such as strontium, calcium and hydrogen.

ABSTRACT The objective of this study was to characterize and understand the investment profile towards technologies for control and automation of climate control on swine farms, focused on integrated producers on the same integration system. A structured questionnaire including open, dichotomic, or multiple-choice questions was responded by 190 integrated producers classified as nursery (28,300 swines), wean-to-finish (WTF; 144,388 swines), or finishing unit (FU; 164,185 swines) farms. Data were described and categorized according to the type of integrated producer (nursery, WTF, and FU) and income history during a 24-month interval. The most predominant farmer profile was of a 44.5-year-old man, with incomplete secondary education. Furthermore, the majority of the farms had family-based labor with an average area of 43.6±65.5 ha and ~2.4 economic activities developed. Overall, a reduced labor availability was observed, although the integrated producers declared to be satisfied with the activities. Interestingly, integrated producers with a better income history declared a longer working (high = 37; average = 31; regular = 31; low = 28 min). The investment profile in automation technologies is conservative; however, potential improvements in pig performance were the most popular justification for potential investments. Furthermore, high costs, knowledge in technologies, interest rates, and quality of the available material are the limiting factors for investing in environment control. A total of 74% of the integrated producers considered the activity as economically profitable. Lastly, the uptake of environmental control technologies is strongly associated with the average income received by farmers.

ABSTRACT This study was developed using meta-analysis to evaluate the effect of β-mannanase on both poultry and pig performance. Two databases were constructed using information from previous studies that evaluated the β-mannanase supplementation in diets for broilers (30 papers; 19,643 birds) and pigs (20 papers; 5,319 animals). The meta-analysis followed three sequential analyses: graphical, correlation, and variance-covariance. The effect of β-mannanase supplementation on performance considerably varied in both databases. Data analysis considering the study effect showed that β-mannanase supplementation did not influence feed intake. Diets supplemented with β-mannanase did not influence weight gain, but improved feed conversion (−1%) of broilers compared with the control group. Feeding pigs diets supplemented with β-mannanase improved weight gain (+5%) and feed conversion (−6%) compared with pigs fed non-supplemented diets. β-mannanase supplementation increased the digestibility coefficient of dry matter, crude protein, and energy in both species. The inclusion of β-mannanase also improved the metabolizable energy content in broiler diets and enhanced the digestibility of energy in pig feeds. Current results indicate that β-mannanase can be considered as an important tool for nutritionists who search for improved feed conversions and nutrient digestibility coefficients.

Resumo: O estudo teve como objetivo avaliar o consumo de alimentos processados e ultraprocessados por crianças entre 13 e 35 meses de idade e fatores associados. Estudamos 1.185 crianças da coorte BRISA em São Luís, Maranhão, Brasil. O consumo alimentar foi investigado com um recordatório de 24 horas, e os percentuais de ingestão diária de calorias e nutrientes foram estimados por grupos de alimentos de acordo com a classificação “NOVA”. Optamos por categorizar as crianças pertencentes ao tercil superior da distribuição como tendo consumo elevado de produtos alimentícios processados e ultraprocessados. Foi utilizado um modelo de regressão Poisson com estimativa robusta de variância com modelagem hierárquica para calcular as razões de prevalência (RPs) das variáveis associadas ao consumo elevado de produtos alimentícios processados e ultraprocessados. A ingestão calórica média era 1.226Kcal/dia. Após os ajustes, houve uma proporção maior de consumo elevado de produtos alimentícios processados e ultraprocessados entre crianças cujas mães tinham menos de 12 anos de escola e entre crianças com mais de 16 meses de idade. As mães com baixa escolaridade e crianças acima de 16 meses devem ser alvos de intervenções para reduzir o consumo desses produtos alimentícios e prevenir os desfechos de saúde adversos na adolescência e idade adulta.

Abstract: The aim of this study was to evaluate the consumption of processed and ultra-processed foods among children aged 13-35 months and its associated factors. We studied 1,185 children within the BRISA cohort in São Luís, Maranhão State, Brazil. The food consumption was investigated using a 24-hour recall, and the percentages of daily caloric intake and nutrients were estimated by food groups according to “NOVA” classification. We chose to categorize children belonging to the upper tertile of the distribution as having a high consumption of processed and ultra-processed food products. The Poisson regression model with robust variance estimation using a hierarchical modeling approach was used to calculate the prevalence ratios (PRs) of variables associated with high consumption of processed and ultra-processed food products. The mean energy intake was 1,226Kcal/day. After adjustments, there was a higher proportion of high consumption of processed and ultra-processed food products among children whose mothers had < 12 years of education and among children who were older than 16 months. Mothers with low schooling and children older than 16 months should be the targets of interventions aimed at reducing consumption of these food products and preventing adverse health outcomes in later life.
