title: CULTIVATION OF XARAÉS GRASS IRRIGATED WITH IRON MINING TAILINGS

description: ABSTRACT The collapse of the Fundão dam in Brazil caused one of the biggest environmental disasters. One of the challenges was how to manage the tailings so that affected areas could be reused. This study aimed to verify whether applying different irrigation depths to Xaraés grass grown with iron mining tailings would affect grass shoot and root dry masses. The experiment was set up in a randomized design with five irrigation depths (40%, 60%, 80%, 100%, and 120% of crop evapotranspiration) and two additional treatments (grass grown in tailings with soil conditioner, and grass grown in natural soil), each with three repetitions. The grass was cut four times, and the shoot dry mass was evaluated after each cut, while the root dry mass was evaluated at the end of the experiment. Our results showed that irrigation depths had a positive linear effect on shoot dry mass and an exponentially increasing effect on root dry mass, with the highest averages in the treatment applying 120% of crop evapotranspiration. This study showed that even in adverse conditions, Xaraés grass was able to grow and develop well.

title: Early diagnosis of autism and other developmental disorders, Brazil, 2013–2019

description: ABSTRACT OBJECTIVE To investigate the factors associated with the early diagnosis of autism and other types of pervasive developmental disorder (PDD) in children treated at the Psychosocial Care Center for Children and Adolescents of the Unified Health System, from 2013 to 2019,in Brazil. METHODS An exploratory cross-sectional study, based on data from the Record of Outpatient Health Actions (RAAS) of the first appointment of children aged 1 to 12 years. The gross (RRg) and adjusted (RRa) relative risks and respective 95% confidence intervals (95%CI) were estimated using the Poisson regression model with robust variance estimation. RESULTS Of the 22,483 children included in the study, the majority were male (81.9%), lived in the same municipality where they were diagnosed (96.8%) and in the Southeast region (57.7%). Early diagnosis was higher for childhood autism (RRg = 1.48; 95%CI 1.27–1.71) , PDD without subtype designation (RRg = 1.55; 95%CI 1.34–1.80), other PDD (RRg = 1.48; 95%CI 1.21–1.81) and PDD not otherwise specified (RRg = 1.44; 95%CI 1.22–1.69) than for atypical autism. Children residing in the same municipality where the diagnosis was made had a higher rate of early diagnosis (RRg = 1.31; 95%CI 1.10–1.55) than the others; as well as those referred by primary care (RRg = 1.51; 95%CI 1.37–1.68) and by spontaneous demand (RRg = 1.45; 95%CI 1.31–1.61) than those from other types of referral. Early diagnosis was higher from 2014 and lower in the North region than in the other regions. In the multiple analysis, the magnitude of RRa was similar to that of RRg. CONCLUSIONS Early identification of autism and other PDD has improved in Brazil, but it still represents about 30% of the diagnoses made. The variables included in the model were significant, but still explain little of the early diagnosis of children with autism and other PDD.

title: Marker events associated with adherence to HIV/AIDS treatment in a cohort study

description: ABSTRACT OBJECTIVE To analyze how clinical and social events may impact adherence to antiretroviral treatment for HIV. METHODS This is a historical cohort study with 528 patients who underwent treatment for HIV in a specialized care service in Alvorada, RS. A total of 3429 queries executed between the years 2004 and 2017 were analyzed. For each visit, data on treatment characteristics and the patients’ clinical picture were collected. Adherence, as measured by patients’ self-report, was the endpoint of the study. The logistic regression model via generalized estimating equations was used for estimating the associations. RESULTS 67.8% of the patients analyzed have up to 8 years of education and 24.8% have a history of crack and/or cocaine use. Among men, being asymptomatic [odds ratio (OR) = 1.43; 95%CI 1.05-1.93], having more than 8 years of education (OR= 2.32; 95%CI 1.27-4.23), and never having used crack (RC = 2.35; 95%CI 1.20-4.57) were associated with adherence. For women, being older than 24 years (CR = 1.82; 95%CI 1.09-3.02), never having used cocaine (CR = 2.54; 95%CI 1.32-4.88) and being pregnant (RC = 3.28; 95%CI 1.83-5.89) increased the odds of adherence. CONCLUSIONS In addition to defined sociodemographic characteristics, one-off events that may occur in the trajectory of patients on long treatment, such as starting a new pregnancy and not having symptoms, can impact patients’ chances of treatment adherence.

title: PVP solid dispersions containing Poloxamer 407 or TPGS for the improvement of ursolic acid release

description: Abstract Solid dispersions (SDs) of ursolic acid (UA) were developed using polyvinylpyrrolidone K30 (PVP K30) in combination with non-ionic surfactants, such as D-α-tocopherol polyethylene glycol 1000 succinate (TPGS) or poloxamer 407 (P407) with the aim of enhancing solubility and in vitro release of the UA. SDs were investigated using a 24 full factorial design, subsequently the selected formulations were characterized for water solubility, X-ray diffractometry (XRD), differential scanning calorimetry (DSC), particle diameter, scanning electron microscopy, drug content, physical-chemical stability and in vitro release profile. SDs showed higher UA water-solubility than physical mixtures (PMs), which was attributed by transition of the drug from crystalline to amorphous or molecular state in the SDs, as indicated by XRD and DSC analyses. SD1 (with P407) and SD2 (with TPGS) were chosen for further investigation because they had higher drug load. SD1 proved to be more stable than SD2, revealing that P407 contributed to ensure the stability of the UA. Furthermore, SD1 and SD2 increased UA release by diffusion and swelling-controlled transport, following the Weibull model. Thus, solid dispersions obtained with PVP k-30 and P407 proved to be advantageous to enhance aqueous solubility and stability of UA.

title: Systematic review on health care for transvestites and transsexuals in Brazil

description: ABSTRACT OBJECTIVE To synthesize scientific evidence to characterize health care for transvestites and transsexuals in Brazil. METHODS This is a systematic review, conducted from July 2020 to January 2021 and updated in September 2021, whose protocol is registered in the International Prospective Register of Systematic Reviews (PROSPERO) platform, under code CRD42020188719. The survey of evidence was carried out in four databases and eligible articles were evaluated for methodological quality, and those with a low risk of bias were included. RESULTS Fifteen articles were selected and the findings were grouped into six categories according to their thematic approaches: Possibilities to transform health care; Transvestiphobia and transphobia: violations inside and outside the Brazilian Unified Health System (SUS); Professional unpreparedness to care for transvestites and transsexuals; Search for health care alternatives; Right to health for transvestites and transsexuals: utopia or reality?; The Transsexualization Process: advances and challenges. CONCLUSIONS There is evidence that health care for transvestites and transsexuals in Brazil is still exclusive, fragmented, centered on specialized care and guided by curative actions, resembling the care models that preceded the SUS and which have been heavily criticized since the Brazilian Sanitary Reform.

title: Fashion Conscious Consumption and Consumer Perception: A Study in the Local Productive Arrangement of Clothing of Pernambuco

description: ABSTRACT This study aims to analyze the relationship between the perception of corporate social responsibility actions (PCSRA) and the purchase of green products (PGP) on price sensitivity (PS) and the influence of these constructs on conscious consumption (CC). For this purpose, a descriptive quantitative study was carried out with fashion consumers of a Local Productive Clothing Arrangement in the Agreste area of Pernambuco, and the data was analyzed using Structural Equation Modeling. The results identified that PGP has an influence on PS and a negative relationship with CC. PCSRA, on the other hand, has a positive influence on CC, but not on PS, and the relationship between PS and CC was not significant. These results indicate that social aspects have a greater predominance over CC, and price does not seem to be a barrier to the consumer’s consciousness regarding the consumption of fashion products. This study innovates by bringing to debate the relationship between relevant constructs that have been investigated separately in the field of consumption.

title: Climate-related variables may not improve monthly scale rainfall predictions by artificial neural networks for the metropolitan region of Belo Horizonte, Brazil

description: Abstract Artificial neural networks (ANNs) may experience problems due to insufficient or uninformative predictors, and these problems are common for complex predictions such as those for rainfall. However, some studies point to the use of climate variables and anomalies as predictors to make the forecast more accurate. This research aimed to predict the monthly rainfall, one month in advance, in four municipalities of the metropolitan region of Belo Horizonte using an ANN trained with different climate variables; additionally, it aimed to indicate the suitability of such variables as inputs to these models. The models were developed using the MATLAB® software Version R2011a using the NNTOOL toolbox. The ANNs were trained by the multilayer perceptron architecture and the feedforward and backpropagation algorithm using two combinations of input data, with two and six variables, and one combination of input data with the three most correlated variables to observed rainfall from 1970 to 1999 to predict the rainfall from 2000 to 2009. The climate variable most correlated with the rainfall of the following month was the average compensated temperature. Even when using the variables most correlated with precipitation as predictors (0.66 ≤ nt index ≤ 1.26), there was no notable improvement in the predictive capacity of the models when compared to those that did not use climate variables as predictors (0.55 ≤ nt index ≤ 0.80).

title: Soil nitrous oxide emissions from a soybean-wheat succession under different tillage systems in Southern Brazil

description: ABSTRACT No-tillage (NT) has been largely adopted in Brazil as a strategy for soil conservation, but for the last decade, there have been governmental incentives for its adoption arising from its potential for soil C accumulation. Notwithstanding, the soil mulch formed from crop residues favors the maintenance of soil moisture and nutrients in the upper soil layers, which stimulates soil microbial activity and may increase the potential for nitrous oxide (N2O) emissions. In addition, double-cropping systems in the same year are typical in Brazil and the impact on the fraction of fertilizer N lost as N2O needs to be evaluated. This study aimed to assess the influence of soil tillage and N fertilization on N2O emissions in a wheat-soybean succession system as commonly practiced in southern Brazil. The experiment was carried out at Embrapa Soybean research station located in Southern Brazil. Treatments were conventional tillage (CT) and no-tillage (NT), with and without nitrogen fertilization for the wheat and no N fertilizer for the soybean. Closed-static chambers were used to monitor N2O fluxes for two consecutive years. Together with gas monitoring, soil samples were also taken and analyzed for mineral N, soil moisture and labile carbon. Soybean yields were higher under NT, which seemed to be the result of a higher soil water availability that helped to overcome extended periods without rainfall. Soil N2O emissions were similar between CT and NT, with just a tendency for higher emissions under NT. The highest emissions occurred from the soybean crop. In the second year under NT, the emissions from the soybean crop were higher when preceded by N-fertilized wheat, but the converse was true under CT. None of the soil variables consistently correlated with N2O emissions, with mineral-N as the best predictor in the second wheat cycle and soil moisture in the first soybean cycle. Calculated emission factors were not statistically different between CT and NT and consistently lower than the IPCC default of 1 %. The calculated N2O emission intensity by relating N2O emission to grain yield showed an environmental advantage of NT compared to CT by presenting a 44 % reduction in soybean and similar values for fertilized wheat.
