This article proposes multilevel modelling to account for individuals' contexts when predicting police confidence. It uses the case study of Brazil considering 107 cities from 25 states to assess four evidence and literature-based predictors impacting police confidence measures in the country. The article found that being a crime victim, experiencing police corruption and having low interpersonal trust were negatively and significantly associated with confidence in the police. Levels of variance between individuals grouped by cities and states were a considerable explanatory feature of police confidence. The implications of these results are discussed in relation to police governance. [ABSTRACT FROM AUTHOR]

Background: The short tenure of primary care physicians undermines the continuity of care, compromising health outcomes in low-, middle and in high-income countries. The purpose of this study was to investigate the contextual and individual factors associated with the tenure of physician in Primary Health Care (PHC) services. We consider individual-level sociodemographic variables such as education and work-related variables, as well as the characteristics of employers and services. Methods: This study is a retrospective cohort study of 2,335 physicians in 284 Primary Health Care Units across the São Paulo, Brazil, public health care system from 2016 to 2020. A multivariate hierarchical model was selected, and an adjusted Cox regression with multilevel analysis was employed. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist was used to report the findings from the study. Results: The average physician tenure was 14.54 ± 12.89 months, and the median was 10.94 months. Differences between Primary Health Care Units accounted for 10.83% of the variance observed in the outcome, while the employing organizations were responsible for only 2.30%. The physician characteristics associated with higher tenure in PHC were age at hire, i.e., being between 30 and 60 years old, [HR: 0.84, 95% CI: (0.75–0.95)] and professional experience over five years [HR: 0.76, 95% CI: (0.59–0.96)]. Specialties not related to PHC practices were associated with a short tenure [HR: 1.25, 95% CI: (1.02–1.54)]. Conclusion: Differences between Primary Health Care Units and in the individual characteristics, such as specializations and experience, are related to the low tenure of professionals, but such characteristics can be changed through investments in PHC infrastructure and changes in work conditions, policies, training, and human resource policies. Finding a remedy for the short tenure of physicians is essential for guaranteeing a robust PHC system that can contribute to universal, resilient, and proactive health care. [ABSTRACT FROM AUTHOR]

The study aimed to characterize women that attended prenatal care in Brazil according to ethnicity/skin color and sociodemographic variables and to verify the association between the indicators of the prenatal care process and the women's ethnicity/skin color. This was a population based, cross-sectional study carried out with data from the National Health Survey of 2013. A bivariate analysis was performed using the multilevel logistic regression model, estimating the odds ratio and the respective 95% confidence intervals to test the association between the indicators of the adequate prenatal care process and the women's ethnicity/skin color. The findings showed that black women have a lower chance of starting prenatal care before 12 weeks of gestation, having 6 or more consultations, performing the HIV test, performing the VDRL exam or receiving advice related to care during gestation and childbirth. Inequalities were identified in the healthcare of Brazilian women during prenatal care, related to ethnicity/skin color and other sociodemographic characteristics. It was concluded that being of black ethnicity and living in a socially disadvantaged area entails disadvantages for women regarding access to a prenatal care considered to be adequate according to the criteria established by the Brazilian Ministry of Health.

Background: We tested if fatigue in incident Peritoneal Dialysis associated with an increased risk for mortality, independently from main confounders. Methods: We conducted a side-by-side study from two of incident PD patients in Brazil and the United States. We used the same code to independently analyze data in both countries during 2004 to 2011. We included data from adults who completed KDQOL-SF vitality subscale within 90 days after starting PD. Vitality score was categorized in four groups: >50 (high vitality), ≥40 to ≤50 (moderate vitality), >35 to <40 (moderate fatigue), ≤35 (high fatigue; reference group). In each country's cohort, we built four distinct models to estimate the associations between vitality (exposure) and all-cause mortality (outcome): (i) Cox regression model; (ii) competing risk model accounting for technique failure events; (iii) multilevel survival model of clinic-level clusters; (iv) multivariate regression model with smoothing splines treating vitality as a continuous measure. Analyses were adjusted for age, comorbidities, PD modality, hemoglobin, and albumin. A mixed-effects meta-analysis was used to pool hazard ratios (HRs) from both cohorts to model mortality risk for each 10-unit increase in vitality. Results: We used data from 4,285 PD patients (Brazil n = 1,388 and United States n = 2,897). Model estimates showed lower vitality levels within 90 days of starting PD were associated with a higher risk of mortality, which was consistent in Brazil and the United States cohorts. In the multivariate survival model, each 10-unit increase in vitality score was associated with lower risk of all-cause mortality in both cohorts (Brazil HR = 0.79 [95%CI 0.70 to 0.90] and United States HR = 0.90 [95%CI 0.88 to 0.93], pooled HR = 0.86 [95%CI 0.75 to 0.98]). Results for all models provided consistent effect estimates. Conclusions: Among patients in Brazil and the United States, lower vitality score in the initial months of PD was independently associated with all-cause mortality. [ABSTRACT FROM AUTHOR]

Civilian control of the armed forces and the absence of military politicization are fundamental democratic norms. In recent years, some democratically elected national leaders, including former Brazilian president Jair Bolsonaro, have subverted these norms. In this article, we, first, evaluate whether the increased national political involvement of the armed forces in Brazil extends to the realm of local politics and, second, discern whether conditions- and demand-based theories explain local-level trends. To do this, we descriptively assess candidacies from 21st-century Brazilian municipal elections and estimate a series of municipality- and multi-level regression models exclusively for the 2020 round. We learn that national politicization has coincided with a marked increase in the number of military candidates, conceptualized as those who use military titles in their electoral campaigns, in Brazilian mayoral and city councilor contests and that municipal support for Bolsonaro is positively associated with military candidates contesting local elections, in line with conditions-based theories, sounding the alarm bells of civil–military weakening.

Background: In Brazil, case-fatality from visceral leishmaniasis (VL) is high and characterized by wide differences between the various political-economic units, the federated units (FUs). This study was designed to investigate the association between factors at the both FU and individual levels with the risk of dying from VL, after analysing the temporal trend and the spatial dependency for VL case-fatality. Methodology: The analysis was based on individual and aggregated data of the Reportable Disease Information System-SINAN (Brazilian Ministry of Health). The temporal and spatial distributions of the VL case-fatality between 2007 and 2017 (27 FUs as unit of analysis) were considered together with the individual characteristics and many other variables at the FU level (socioeconomic, demographic, access to health and epidemiological indicators) in a mixed effects models or multilevel modeling, assuming a binomial outcome distribution (death from VL). Findings: A linear increasing temporal tendency (4%/year) for VL case-fatality was observed between 2007 and 2017. There was no similarity between the case-fatality rates of neighboring FUs (non-significant spatial term), although these rates were heterogeneous in this spatial scale of analysis. In addition to the known individual risk factors age, female gender, disease's severity, bacterial co-infection and disease duration, low level schooling and unavailability of emergency beds and health professionals (the last two only in univariate analysis) were identified as possibly related to VL death risk. Lower VL incidence was also associated to VL case-fatality, suggesting that unfamiliarity with the disease may delay appropriate medical management: VL patients with fatal outcome were notified and had VL treatment started 6 and 3 days later, respectively, in relation to VL cured patients. Access to garbage collection, marker of social and economic development, seems to be protective against the risk of dying from VL. Part of the observed VL case-fatality variability in Brazil could not be explained by the studied variables, suggesting that factors linked to the intra FU environment may be involved. Conclusions: This study aimed to identify epidemiological conditions and others related to access to the health system possibly linked to VL case-fatality, pointing out new prognostic determinants subject to intervention. Author summary: Visceral leishmaniasis (VL) is a potentially fatal disease if not diagnosed and treated promptly. The VL case-fatality in Brazil is the highest rate in the world, reaching an average of 7% and in some regions, more than 15%. In the last years, some improvements in the VL approach have been reached in Brazil, such as the widespread use of rapid diagnostic tests and liposomal amphotericin B for treatment of selected high risk of death cases. Despite these interventions, increase in case-fatality rates were observed. In this study we explored the factors related to the case-fatality from VL using a mixed modeling that encompasses different intervening factors such as time/spatial trends and factors linked to the individual and socio-economic indicators. For the first time, factors unrelated to the patients' clinical condition emerge as possibly related to VL case-fatality, such as low educational level, unavailability of emergency beds and health professionals, suggesting the harmful influence of conditions of limited access to health services. In addition to these significant effects observed in the spatial scale of analysis, this study points to the influence of contextual factors linked to each geopolitical unit. The determinants of death among VL cases may differ according to the region, which requires specific actions planned locally, including increased access to health system qualified to recognize and properly treat VL.

Initiatives to foster a transition toward organic agriculture have drawn policy-makers' interest worldwide. However, research studies evaluating the effectiveness of policies intended to promote 'scaling-out' organic production systems to more farms and larger production areas are still rare. To better understand the role that public procurement and price incentive policies have in scaling-out organic transitions, we assessed the effects of the Brazilian Food Acquisition Program (PAA) in a group of municipalities. PAA offers both markets for family farmers and price incentives for certified organic products. However, our findings suggest that farmers who establish organic production systems and become certified also gain access to other markets; ones that they find more attractive than those created by the PAA. Thus, we find that the PAA offers insufficient incentives for adopting organic practices among peasant and family farmers and supports the argument that scaling-out organic production is a multilevel process that depends on different, but interrelated drivers.

A nationwide survey of dentists was carried out in Brazil, a new pandemic epicenter, to analyze how dental care coverage has been affected in public versus private networks, changes in routine and burdens, and how local prevalence of COVID-19 affects dental professionals. Dentists were recruited via email and Instagram®. Responses to a pre-tested questionnaire were collected May 15–24, 2020. COVID-19 case/death counts in the state where respondents work was used to test associations between contextual status and decreases in weekly appointments, fear of contracting COVID-19 at work, and current work status (α = 0.05). Over 10 days, 3,122 responses were received (response rate ~2.1%) from all Brazilian states. Work status was affected for 94%, with less developed regions being more impacted. The pandemic impact on clinical routine was high/very high for 84%, leading to varied changes to clinic infrastructure, personal protective equipment use, and patient screening, as well as increased costs. COVID-19 patients had been seen by 5.3% of respondents; 90% reported fearing contracting COVID-19 at work. Multilevel models showed that greater case and death rates (counted as 1000 cases and 100 deaths per million inhabitants) in one's state increased the odds of being fearful of contracting the disease (18% and 25%). For each additional 1000 cases/100 deaths, the odds of currently not working or treating only emergencies increased by 36% and 58%. The reduction in patients seen weekly was significantly greater in public (38.7±18.6) than in private clinics (22.5±17.8). This study provides early evidence of three major impacts of the pandemic on dentistry: increasing inequalities due to coverage differences between public and private networks; the adoption of new clinical routines, which are associated with an economic burden for dentists; and associations of regional COVID-19 incidence/mortality with fear of contracting the disease at work.

Brazil is characterized by a sharp consumption market and cultural activities across its distinct locations and social groups. With this in mind, this paper focuses on the relationship between supply of cultural facilities in Brazilian Metropolitan Regions (MR) and household expenditure on outdoor cultural activities through estimation of a two-stage (households and MRs) multilevel logistic model, using microdata from the Brazilian Consumer Expenditure Survey of 2002–2003 and 2008–2009. It was concluded that there is a strong concentration of expenditure distribution among different socioeconomic groups, and that expenditures on outdoor cultural activities (movies, concerts and arts) have demonstrated to be weakly correlated with the qualities of the different study Brazilian MRs, because greater variability of expenditure occurs within these regions. Thus, we also confirmed the hypothesis that recent advances in cultural policies have not been enough to reverse the inertia of inequality. Therefore, public initiatives in favor of cultural democratization, especially for inclusion of lower classes in cultural spaces, should consider the issue comprehensively, combining institutional supply issues, urban policy and public education.

Summary: Among the many disparities for which Brazil is known is the difference in performance across students who attend the three administrative levels of Brazilian public schools: federal, state and municipal. Our main goal is to investigate whether student performance in the Brazilian Mathematical Olympics for Public Schools is associated with school administrative level and student gender. For this, we propose a hurdle hierarchical beta model for the scores of students who took the examination in the second phase of these Olympics, in 2013. The mean of the beta model incorporates fixed and random effects at the student and school levels. We explore different distributions for the random school effect. As the posterior distributions of some fixed effects change in the presence, and distribution, of the random school effects, we also explore models that constrain random school effects to the orthogonal complement of the fixed effects. We conclude that male students perform slightly better than female students and that, on average, federal schools perform substantially better than state or municipal schools. However, some of the best municipal and state schools perform as well as some federal schools. We hypothesize that this is due to individual teachers who successfully motivate and prepare their students to perform well in the mathematical Olympics. [ABSTRACT FROM AUTHOR]

This article seeks to provide theoretical and managerial insights with respect to the following questions: What is the effect of network management on the outcomes of associated firms? Do these effects on outcomes vary among small-firm networks (SFNs)? Do these outcomes vary among associated firms within the same SFN? Which management elements are most influential in the variation of these SFN outcomes? To answer these questions, this study adopts a multilevel analytical approach using SFNs in southern Brazil that benefit from the Cooperation Networks Program, a local public policy initiative that supports the formation, development, and consolidation of SFNs. The findings suggest that the outcomes provided by the networks differ between networks but are similar for firms in the same network. They also indicate that strategy and processes at the network level are related to firms' outcomes. These findings show that the influence of structure on firms' outcomes varies among networks and that the market segment is the only network-level variable that is significantly related to firms' outcomes.

The Brazilian cerrado occurs interspersed with the semi-deciduous seasonal forest, and soil fertility is considered as the main determinant of the abrupt transitions between both vegetation types. We aimed to study patterns across chemical traits of green leaves in 121 cerrado and seasonal forest woody species from southeastern Brazil, their response to soil nutrient status, and their effects on decomposition rates. We compared leaf traits of both cerrado and forest species and constructed multilevel models to account for partitioning of variance in each trait. We calculated the community-weighted mean of each trait to assess their response to soil nutrient status and their effects on decomposition rates of standard plant material. Most of the traits were significantly correlated among themselves, with cerrado species having lower nutrient concentrations than the seasonal forest. Taxonomy accounted for 52 % of the total variance in leaf traits, whereas vegetation type accounted for 19 %. All leaf traits but leaf manganese and aluminium concentrations were significantly related to soil properties. Decomposition rates were affected indirectly by soil features through its effects on leaf traits. Contrary to the expected, the higher the leaf nitrogen concentration in the surrounding litter, the lower the decomposition rate. Even with a large effect of taxonomy on leaf nutrient-related traits, soil exerted an important role on the chemical traits. Strategies of both cerrado and seasonal forest species were carried out through multi-element control of soil on leaf nutrient composition. The effect of such different strategies on functioning was, however, less prominent. [ABSTRACT FROM AUTHOR]

[Display omitted] • ▪ Temperature and rainfall regulate Sclerotinia sclerotiorum sclerotia parasitism. • ▪ Temperature (27 °C and up) and rainfall (250 mm and up) reduce biocontrol activity. • ▪ Formulations of biological control agents reduce carpogenic germination in ca. 9%. Biocontrol is a plausible strategy to be considered on the management of white mold but the efficacy is not always the same. Therefore, the identification of the sources of such variable performance fosters a fine-tune product recommendation to achieve the highest performance. Based on seven soybean crop seasons, 59 uniform field trials were conducted throughout Brazil to assess the performance of Sclerotinia sclerotiorum sclerotia parasitism under different temperature and rainfall regimes. Hence, we carried out a meta -analysis to evaluate the effect of three treatment classes (Trichoderma- , Bacillus- , and a Mixed combination of both organisms) on the reduction of S. sclerotiorum sclerotia carpogenic germination (mean difference; MD) according to a multilevel network model (59 trials, k = 340). Throughout trials included in the meta -analysis, biocontrol reduced carpogenic germination ca. 70 % of times, with fitted MD ¯ values of − 10.6 for Bacillus , −8.6 for Trichoderma , and − 7.0 for Mixed Bacillus and Trichoderma groups. Separate network models were then fitted to determine the influence of average monthly temperature (AMT) and average monthly rainfall (AMR) under three classes (low, moderate, and high) for each variable on the carpogenic germination. Overall, interactions of treatments and low or moderate AMT and AMR were significant (p < 0.1). Temperatures above 27 °C and precipitation higher than 250 mm have not contributed to the reduction in carpogenic germination regardless of the considered active ingredient. Hence, biocontrol product́s reduce carpogenic germination in ca. 9 % and dominant weather conditions. These relationships are important factors involved in sclerotia colonization and therefore, high temperatures and rainfall should not be indicated for the product's application for best BCAs performance.

Several studies have indicated that student performance is strongly influenced by school context. Within this frame of reference, the present study sought to identify contextual variables that affect proficiency in mathematics taking the multilevel structure of schools into consideration. The information of 4,338,885 students who participated in the Brazilian national assessment of educational progress of 2009 was used. Multilevel analysis showed an intra-class correlation of .27 and .19 for the 5th grade of elementary school and 9th grade of middle school, the last year of middle school. In both models, more than 50% of school level variance and more than 11% of the variance on student level was explained. The final model is composed of control variables, 13 student level variables, 9 school level variables, and random and interaction effects. The results contribute to a better comprehension of factors that affect school performance, which permits the orientation of public policies. [ABSTRACT FROM AUTHOR]

Ultra-processed drinks (UPDs) consumption is increasing, and this intake has been associated with the risk of illness and death. Data on individuals (n = 430) and food stores (n = 231) were collected in an economically vulnerable area in Recife-Brazil, and multilevel regression models were applied to assess the association between UPDs consumption with food environment characteristics. The results show 29.5% of individuals consume UPDs, higher UPD consumption was significantly associated with age (OR: 0.96), lower educational levels (OR:2.06), high density of stores predominantly selling UPFs (OR:2.34) and lower availability of FV in stores (OR:0.49). The applied methodology can inform food environment interventions to reduce UPDs consumption. [ABSTRACT FROM AUTHOR]

Background: Environmental, social and individual factors influence eating patterns, which in turn affect the risk of many chronic diseases. This study aimed to estimate associations between environmental factors and the consumption of fruit and vegetables among adults in a Brazilian urban context.Methods: Data from the surveillance system for risk factors for chronic diseases (VIGITEL) of Brazilian Ministry of Health were used. A cross-sectional telephone survey (VIGITEL - 2008-2010) was carried out with 5826 adults in the urban area of Belo Horizonte. Individual variables were collected. The frequency of fruit and vegetables consumption was assessed from number of servings, weekly frequency and an intake score was calculated. Georeferenced variables were used to characterize the food environment. The density of healthy food outlets (stores specialized in selling fruit and vegetables), unhealthy food outlets (bars, snack bars and food trucks/trailers) and the neighborhood family income were investigated and associated with fruit and vegetables intake score. Weighted multilevel linear regression was used to evaluate the associations between the environment variables and the fruit and vegetables intake score.Results: Higher fruit and vegetables intake scores were observed in neighborhoods with higher density of healthy food outlets and higher income. Lower scores were observed in neighborhood with higher density of unhealthy food outlets. These associations were adjusted by individual variables such as gender, age, physical activity, sugar sweetened beverages consumption, education level and smoking.Discussion: The food environment might explain some of the socioeconomic disparities with respect to healthy food intake and health outcomes. Healthy food stores are less common in socially disadvantaged neighborhoods, and therefore, healthy foods such as fruits and vegetables are less available or are of a lower quality in lower income areas.Conclusion: Food environment characteristics and neighborhood socioeconomic level had significant associations with fruit and vegetable intake score. These are initial findings that require further investigation within the middle income world populations and the role of the environment with respect to both healthy and unhealthy food acquisition and intake.

Objective. To evaluate gingival and calculus status among schoolchildren 12 years of age using a geographic information system and multilevel analysis. Methods. A total of 1 002 schoolchildren were selected from 18 municipal districts by means of cluster sampling, from among 25 public and private schools in Piracicaba, São Paulo, Brazil, in 2005. Examinations were carried out by a single calibrated examiner utilizing the criteria of the World Health Organization, as well as the Community Periodontal Index. Social, economic, and behavioral variables were recorded with the use of a questionnaire and were used in the individual analysis (first level). The variables "percentage of heads of families without income" and "percentage of illiterate heads of families" were used in the contextual analysis (second level). Results. A geographic information system was constructed for mapping the distribution of gingival bleeding. The variables were visually distinguished in the maps and demonstrated a tendency toward better gingival health in the central areas of the city, which are recognized as more privileged. On the contextual level, only the "percentage of illiterate heads of families" was significantly associated to gingival bleeding. Conclusions. The study confirms better oral health status among schoolchildren from privileged families, but does not confirm the data regarding "income." The individuals from areas in which the heads of family did not have income were not associated to a higher prevalence of gingival problems. This suggests that these individuals are reasonably protected from the impact of social privation due to the actions of public health care services in the municipality. [ABSTRACT FROM AUTHOR]

Objective: To investigate covariates that could affect the variation in mean length/age z scores in the first year of life of children born full term with normal birth weight. Methods: This was a prospective study of a cohort of mother-infant pairs recruited at public maternity units in two municipalities in the Brazilian state of Bahia, from March 2005 to October 2006. This paper reports the results for linear growth of 489 children who were followed-up for the first 12 months of their lives. A mixed-effect regression model was used to investigate the influence of covariates of mean length/age z score during the first year of life. Results: The multivariate mixed effect analysis indicated that mothers not cohabiting with a partner (β = 0.2347; p = 0.004) and increased duration of exclusive breastfeeding (β = 0.0031; p < 0.001) had a positive impact, whereas mother's height less than 150 cm (β = -0.4393; p < 0.001), birth weight of 2,500-2,999 g (β = -0.8084; p < 0.001) and anemia in the child (β = -0.0875; p < 0.001) all had a negative impact on the variation in estimated length/age z score. Conclusions: Therefore, the results of this study indicate that short maternal stature, birth weight < 3,000 g and anemia in the infant had a negative effect on linear growth during the first year of life, whereas longer duration exclusive breastfeeding and mothers who did not cohabit with a partner had a positive effect.

Objective. To examine the link between tooth loss and multilevel factors in a national sample of middle-aged adults in Brazil. Material and methods. Analyses were based on the 2003 cross-sectional national epidemiological survey of the oral health of the Brazilian population, which covered 13 431 individuals (age 35–44 years). Multistage cluster sampling was used. The dependent variable was tooth loss and the independent variables were classified according to the individual or contextual level. A multilevel negative binomial regression model was adopted. Results. The average tooth loss was 14 (standard deviation 9.5) teeth. Half of the individuals had lost 12 teeth. The contextual variables showed independent effects on tooth loss. It was found that having 9 years or more of schooling was associated with protection against tooth loss (means ratio range 0.68–0.76). Not having visited the dentist and not having visited in the last ≥3 years accounted for increases of 33.5% and 21.3%, respectively, in the risk of tooth loss ( P < 0.05). The increase in tooth extraction ratio showed a strong contextual effect on increased risk of tooth loss, besides changing the effect of protective variables. Conclusions. Tooth loss in middle-aged adults has important associations with social determinants of health. This study points to the importance of the social context as the main cause of oral health injuries suffered by most middle-aged Brazilian adults. [ABSTRACT FROM AUTHOR]

• We verified that infrastructure negatively affects the levels of household poverty in Brazil. • These effects are strengthened when infrastructure quality and access are greater. • Our results also indicate that there are important spatial heterogeneities in household poverty. • Infrastructure policies should take into account the heterogeneities of the infrastructure in the regional scope. Many scholars have highlighted the role of infrastructure investments in promoting economic growth along with poverty reduction and social inclusion. Developing economies show substantial discrepancies in terms of infrastructure in the rural–urban, regional and income dimensions. These disparities may be reinforcing a social and economic framework marked by a large portion of the population living in poverty. In a scenario characterized by immense regional and income heterogeneities, the present study aims to evaluate the effect of infrastructure investments on household poverty in Brazil. In addition, we verify whether these effects vary according to infrastructure characteristics such as provision, quality and access. The analysis is based on detailed household microdata from the Demographic Census and infrastructure variables at the municipal and state levels, captured from a variety of data sources. An additional contribution of the paper is the novel application of multilevel logistic models to investigate the relationship between infrastructure and poverty at household, municipal and state levels. Our results demonstrate negative effects of the infrastructure provision on poverty. These effects, in turn, are strengthened when infrastructure quality and access are greater, which allows us to infer about the importance of public policies aimed at achieving lower inequalities in access to basic sanitation, Internet, transportation, telephone services and electricity. These policies should also take into account the infrastructure heterogeneities at the regional level, since such heterogeneities have been important in explaining household poverty.

Data from composition of milk from 301 buffaloes served as sample for this study, with a total of 2833 observations over a period of 18 months (May 2008 to September 2009). The animals were from a commercial herd, milked mechanically, and located in a region with harsh climate, northeast of Brazil. The objective of this study was to evaluate how the time data were collected (month, year) affected the components of milk, describing the influence of environmental factors. Concentrations of fat (F), lactose (L), protein (P), solid (S), somatic cell count (SCC) and somatic cell score (SCS) were measured. A polynomial linear regression model was use as variable for time. The variable SCS was also analyzed by means of covariance functions (VC, CS, HCS, AR (1), ARH (1)), to interpret the relationship between the different observations. The best polynomial models for the variables were: S - linear, F - quadratic, L, SCC and SCS - cubic; P - grade four. The conclusion is that variations found are consistent with expectations for the region, based on nutrition and pasture (F, L, P) and the influence of climate on the occurrence of subclinical mastitis (SCS and SCC). The covariance function with the worst shape was the VC (variance components) and the one with best shape was the HCS (heterogeneous compound symmetry), showing that there is a correlation between the different measures, and that the relationship between them tends to shrink as the time interval between the different measures grows. The influence of environmental factors on milk composition suggests the search for alternatives to minimize their impact on milk composition and health of buffaloes, with particular attention to the rainy season when there is an increase on the content of somatic cells.

Most of the epilepsy longitudinal studies have analyzed children. However, in endemic regions, such as Brazil, neurocysticercosis accounts for many adult-onset epilepsy cases. So, the main objective of this study was to identify the clinical predictors associated with drug-resistant adult-onset epilepsy in Brazil during a long-term follow-up. We followed 302 individuals with adult-onset epilepsy for 9.8 years in our University Hospital. Structured questionnaires about drug-resistant epilepsy were applied. The presence of drug-resistant epilepsy was the primary outcome. We used multilevel linear modeling in our data analysis. Overall 47 (15.6%) individuals presented drug-resistant epilepsy and the etiology was structural in 70.2% of them, while infectious etiology was present in 8.5% of this group. Infectious etiology occurred in 25.9% (n = 66) of the patients from the nondrug-resistant group. Those with developmental delay were two times more likely to present seizures. Structural epilepsy etiology was associated with an increased chance of relapsing. Poor school performance and abnormal electroencephalogram were also associated with an increased chance of seizures. The course of epilepsy was favorable in the majority of our patients, and drug-resistant epilepsy rates were similar to those found in other studies, although we evaluated older individuals with higher levels of infectious etiology. Also, we found that neurocysticercosis was associated with well-controlled epilepsy, while structural epilepsy was directly related to the occurrence of seizures. We also hypothesized that the smaller size of lesions found in neurocysticercosis could contribute to better treatment response. • Neurocysticercosis was associated with well-controlled epilepsy in our study. • Structural etiology was associated with drug-resistant epilepsy. • Developmental delay, Poor school performance, and abnormal EEG were also associated with an increased chance of seizures.

Objectives: To investigate the association between personal, relational and school factors with involvement in fights with weapon among Brazilian school-age youth., Methods: Using data from the Adolescent School-Based Health Survey 2015 (n = 102.072), we conducted multilevel logistic regression models., Results: IFW was associated with female sex (OR = 0.45), and with older age (OR = 1.15), previous involvement in physical violence (OR = 2.05), history of peer verbal (OR = 1.14) and domestic victimization (OR = 2.11), alcohol use (OR = 2.42) and drug use (OR = 3.23). The relational variables (e.g., parent's supervision) were mostly negatively associated with IFW. At the school level, attending public school and attending schools in violent surroundings were both positively associated with IFW. The intraclass correlation coefficient estimated in the empty model showed that 5.77% of the variance of IFW was at school level. When all individual- and school-level variables were included in the model, the proportional changes in variance were 61.7 and 71.55%, respectively., Conclusions: IFW is associated with personal, relational and school factors. Part of the variance in IFW by school is explained by characteristics of the school context.
