title: Modeling multivariate time series with copulas: Implications for pricing revenue insurance

description: Much of the soybean produced in Brazil is exported and, consequently, the domestic soybean price (R$) is greatly influenced by the price traded at the Chicago Mercantile Exchange Group (CME Group) (US$). Therefore, to model the dependency structure between soybean yield and price, the exchange rate must be incorporated into the modeling. This study aims to model the dependency structure between these three variables using the Copula methodology, calculate the crop revenue insurance rates, and compare with the rates offered in the insurance market. The rates applied by the Brazilian insurance market are overpriced when compared to the methodology presented in this study with the incorporation of the dollar rate in the modeling, which could increase the problem of adverse selection exchange and hamper massification of agricultural insurance in the Brazilian territory.

title: Temporal trends and projections of caesarean sections in Brazil, its administrative macro-regions, and federative units

description: Abstract Trend studies on the model of birth in Brazil show a scenario of successive linear increases in cesarean rates. However, they ignore possible changes in the temporal evolution of this delivery modality. Thus, this study aimed to evaluate possible inflection points in cesarean rates in Brazil, its macro-regions, and federated units, as well as to estimate projections for 2030. A time series with information on cesarean sections from 1994 to 2019 from the SUS Department of Informatics was used. Autoregressive integrated moving average and joinpoint regression models were used to obtain cesarean rate projections and trends, respectively. Caesarean rates showed a significant upward trend over the 26 study years at all levels of aggregation. On the other hand, when considering the formation of segments, a stabilization trend was observed both in the country and in the South and Midwest regions, starting in 2012. Rates tended to increase in North and Northeast and significantly decrease in Southeast. Projections show that in 2030, 57.4% of births in Brazil will be cesarean, with rates higher than 70% in Southeast and South regions.

title: Disrespect and abuse during childbirth and postpartum depression: a scoping review

description: This study aims to map, within the scientific literature, the relationship between disrespect and abuse during childbirth and the occurrence of postpartum depression. This is a scoping review designed in accordance with the recommendations of the Joanna Briggs Institute. The search was performed in Embase, LILACS, MEDLINE, PsycINFO, Web of Science, and in the CAPES Portal of Theses and Dissertations. We included studies that investigated the relationship between disrespect and abuse during childbirth with postpartum depression, considering cases diagnosed by physicians and by self-reports via validated scales, without restrictions regarding the year of publication and language. A total of 3,399 publications were identified and, after removing the duplicates and reading the title, abstracts, and the full-texts, seven articles were selected to integrate this review. Studies were published from 2017 onward, in four countries. Women who had experienced disrespect and abuse during childbirth were more likely to experience symptoms of postpartum depression. A standard terminology is necessary for disrespectful and abusive care during childbirth, as well as the elaboration of a measurement instrument that is universally accepted.

title: Interrelationships between dissatisfaction with teaching work and depressive symptoms: Structural equation modelling

description: Abstract The objective of this article is to evaluate the interrelationships of factors associated with depressive symptoms (DS) in teachers, considering dissatisfaction with the teaching job as a possible mediator. This was a cross-sectional study using data from 700 teachers from the public school system of a Brazilian municipality. The outcome of interest was DS, as assessed using the Beck Depression Inventory (BDI). Direct and indirect interrelationships between the outcome and dissatisfaction with work, age, income, lifestyle and adiposity were tested. These variables composed the operational model tested by structural equation modelling. Older age (β=0.12) and greater dissatisfaction with work (β=0.12) were directly associated with DS. A more favourable lifestyle (β=-0.60) and adiposity (β=-0.10) were associated with a lower occurrence of DS. The variables lifestyle (β=-0.06) and adiposity (β=-0.02) also had negative indirect effects on DS, mediated by job dissatisfaction. The structural equation model tested identified interrelationships that influenced DS. Dissatisfaction with teaching work was associated with DS and mediated the relationship of other factors with such symptoms.

title: The inverse equity hypothesis in the implementation of NASF-AB in municipalities of Southern Brazil

description: Abstract The present study aimed to analyze the evolution of the implementation of Family Health and Primary Health Care Expanded Support Centers (NASF-AB, in Portuguese) in the municipalities of Southern Brazil, from 2008 to 2019, in light of the inverse equity hypothesis. This was an ecological study, considering 1,188 municipalities of Southern Brazil. The analyses were separated by state, with municipalities divided into quartiles of Municipal Human Development Index - Income (MHDI-Income). Our study calculated the cumulative percentage of the implementation of NASF-AB within the given period and the inequality between Q1 (richest) and Q4 (poorest), assessed by the absolute and relative inequality measures. In Paraná, Q1 presented a higher coverage of NASF-AB than did Q4, and, although the inequality had decreased at the end of the period, it was still quite distinct, according to the “top inequality” pattern. In Santa Catarina, the predictions of the hypothesis were confirmed, with inequalities found in the beginning of the period and a near 90% decline once NASF-AB had been implemented in the municipalities of Q1, characterizing the “bottom inequality” pattern. In Rio Grande do Sul, the hypothesis was refuted observing that since 2014 there was a greater implementation in Q4 as compared to Q1 was observed.

title: Potassium fertilization and bioactivators on the soybean yield and soil microbiota

description: ABSTRACT Soil microorganisms are of paramount importance for crop yield. This study aimed to evaluate the effect of potassium chloride doses associated with two bioactivation sources on soybean yield and soil microbial activity. The experimental design was randomized blocks, arranged in a 5 x 2 factorial scheme, with four replications, being the first factor potassium doses (0, 30, 60, 90 and 120 kg ha-1 of K2O), using potassium chloride as a source, and the second factor soil bioactivation products: Penergetic (250 g ha-1) and Efficient Microorganisms (EM) (1:250), with 250 L ha-1 of spray volume. The KCl doses affected the soil microbial activity, while the soil bioactivating sources with the potassium chloride doses did not show significance for the leaf potassium content and soybean yield. K2O doses higher than the maintenance dose for the soybean crop with EM negatively influenced the soil microbial biomass. The EM bioactivator associated with the maintenance dose of K for the soybean crop (60 kg ha-1) is the most appropriate treatment for soil microbial activity, as it is the condition that presents the most stable environment and the highest microbial efficiency.

title: Deeper exploration of inflammatory cell populations in milk to monitor udder health in dairy cows

description: ABSTRACT The present study explored the predictive values of milk leukocyte differentials (MLD) as a basis for improving the diagnosis of intramammary infections (IMIs) and subclinical mastitis. Quarter milk samples were collected for bacteriological analysis, quarter somatic cell count (qSCC), and MLD. The MLD were assessed using the cytospin technique, direct microscopic smears, and flow cytometry. The predictive values of each single leukocyte population and useful potential indices that could better reflect immune complexity were also calculated. Changes in the percentage of any leukocyte alone failed to substantially improve the predictive value of qSCC in diagnosing IMIs. Although certain parameters increased the area under the receiver operating characteristic curve (ROC curve) as a result of increased specificity values, a slight reduction in sensitivity was observed. The so-called CD8 complex was a unique parameter which improved both the sensitivity (78.79 %) and the specificity (80.77 %) in IMI diagnosis, resulting in the highest area under the ROC curve (0.87). To diagnose subclinical mastitis, the percentage of macrophages and the sum of the percentage PMNLs and T CD8+ cells divided by the percentage of macrophages showed the highest predictive values (sensitivity = 79.63, specificity = 73.68, and area under the ROC curve = 0.83) in the differentiation of the inflammatory condition status of cows. In conclusion, this study provides further insights into using T CD8+ lymphocytes in diagnosing bovine IMIs, combined with PMNLs and macrophages. The antidromic trend of macrophages vs. PMNLs and T CD8+ lymphocytes due to the increasing qSCCs was crucial to differentiating quarters under both inflammatory and non-inflammatory conditions.

title: Association between social capital and food patterns in women from Southern Brazil

description: Abstract The present study aimed to verify the association between psychosocial aspects (social capital) and food patterns in adult women. A cross-sectional, population-based study was conducted with a representative sample of 1,128 women, aged 20 to 69 years, living in the urban area of the municipality of São Leopoldo, Rio Grande do Sul, Brazil, in 2015. The food patterns were identified based on the frequency of food intake and classified as: healthy (fruits, vegetables, and whole foods), at-risk (ultraprocessed foods), and Brazilian (rice and beans), while social capital was evaluated using a collective efficacy scale. It was observed that 18.9% of the sample was classified with high collective efficacy. After adjusting for potential confounding factors, a 44% higher probability was observed for adherence to the healthy pattern (PR [prevalence ratio] = 1.44; 95%CI [95% confidence interval]: 1.01-2.03; p = 0.040) and 71% higher for the Brazilian pattern (PR = 1.71; 95%CI: 1.18-2.47; p= 0.004) among women with a higher level of collective efficacy, when compared to those with a low level of collective efficacy. Thus, this study verified a significant relationship between psychosocial aspects and food intake in women.

title: Clinical trials of COVID-19 vaccine development: a global overview

description: Abstract: This study aims to report analyses regarding the global distribution of institutions involved in clinical trials of COVID-19 vaccines throughout February 2022. We retrieved global data from the World Health Organization report on vaccine development. These data allowed us to identify project institutions and plot their geographic coordinates. We produced a georeferenced map using an R programming environment and, based on the geographical location of vaccine developers, we analyzed the subcontinental distribution of clinical trials and the nature of the vaccines. Regionally, South-Southeast Asian countries carried out more clinical trials than any other region, proportionally, although this happened solely for mature technologies. Few trials were under implementation in Latin America and Africa. Our findings confirm previous studies on the regional concentration in the development of technology. However, our contribution lies in showing these phenomena for COVID-19 vaccines in specific subcontinents and technologies, at a country level. Our data underscores which subcontinents perform very few clinical trials for COVID-19 and seem to be ill-prepared for future disease outbreaks, and if these become epidemics or even pandemics and require domestic vaccine development or production. We also consider the case of Brazil, which did not finish the complete cycle of COVID-19 vaccine development in the indicated period; but, with favorable policies, it has potential to engage further in COVID-19 vaccine technology.
