title: Layered Double Hydroxides with the Composition Mn/Al-SO4-A (A = Li, Na, K; Mn:Al ca. 1:1) as Cation Exchangers

description: Hydrated Mn/Al-SO4-A (A = Li, Na or K) layered double hydroxides with M2+:M3+ molar ratio close to 1:1 were synthesized by co-precipitation with increasing pH. All phases presented solvated alkali metals and sulfate as intercalated species. In the exchange reactions, when sulfate solutions of alkali metals were used, sodium could be partially replaced by potassium, and the same was true for the potassium phase, where potassium could be partially replaced by Na and Li, without removing the intercalated sulfate anions. This class of compounds, considered to be anion exchanger, can also exchange cations, which opens new perspectives for applications.

title: Acanthocephalan parasites of the flounder species Paralichthys isosceles, Paralichthys patagonicus and Xystreurys rasile from Brazil

description: Abstract Flounders are commercially and economically important fish. A total of 120 specimens of flounders (60 Paralichthys isosceles, 30 Paralichthys patagonicus and 30 Xystreurys rasile) were collected off the coast of the state of Rio de Janeiro, Brazil. The fish were measured, necropsied and filleted, and then had their organs investigated for acanthocephalans. Taxonomic identification of the parasites was based on morphological, morphometric and genetic characters. Paralichthys isosceles and P. patagonicus were parasitized by juveniles of Serrasentis sagittifer, Bolbosoma turbinella, Corynosoma australe and C. cetaceum; Xystreurys rasile was parasitized by C. australe. Genetic characterization confirmed the identification of specimens of Bolbosoma turbinella and Corynosoma australe, as demonstrated by phylogenetic analyses using both ITS and cox1 molecular targets. Parasite indices of prevalence, intensity, mean intensity, abundance, mean abundance, and range of infection, as well as infection site, were evaluated for each parasite species. This is the first report of S. sagittifer parasitizing P. isosceles and P. patagonicus, and B. turbinella parasitizing P. patagonicus.

title: Tuberculosis: knowledge among nursing undergraduate students

description: ABSTRACT Objective: To analyze the knowledge about tuberculosis among nursing undergraduate students of a Federal Higher Education Institution. Method: Descriptive cross-sectional study, with quantitative approach. Data were collected through a questionnaire based on the WHO’s guide to developing evaluation instruments on knowledge, attitudes and practices related to TB. Students were classified as “with knowledge” and “with little knowledge” based on the mean percentage of correct responses to the variables analyzed. Descriptive statistics techniques were used. Results: 60 nursing students were interviewed. “with little knowledge” was observed among students who were studying at the university for less time and who had no previous contact with the subject, and “with knowledge” was observed among those whose knowledge about tuberculosis was acquired in the health services. Conclusion: Knowledge gaps among undergraduate nursing students were identified, suggesting the need to rethink teaching-learning strategies on the subject.

title: First molecular detection of Mycoplasma ovis (Hemotropic mycoplasmas) from Sheep in Brazil

description: Abstract Mycoplasma ovis is an emerging zoonotic pathogen with a worldwide distribution and can cause mild to severe hemolytic anemia, icterus, and poor weight gain in animals. Although M. ovis has been described in small ruminants worldwide, data on M. ovis in sheep in Brazil is unknown. The objective of the present study was to present the first report of hemotropic mycoplasma (HM) in sheep from Brazil. We evaluated factors associated with this infection, such age group, tick presence, and anemia. Blood samples were collected from 33 sheep from a farm in southern Brazil and screened for hemoplasmas using PCR. Out of 33 samples, 26 (78.8%) tested positive for M. ovis. The sequencing of positive samples showed 100% identity with multiple M. ovis 16S rDNA sequences. No association was observed between the presence of M. ovis and the FAMACHA© score (p = 0.620). Rhipicephalus (Boophilus) microplus (15/33, 45.4%) was the tick species found on the animals. No significant association between M. ovis infection and presence of ticks (p = 0.4134) and age group (p = 0.4221) was observed. This is the first report of M. ovis infection in sheep from Brazil and only the second report of this pathogen in sheep in Latin America.

title: Global warming decreases the morphological traits of germination and environmental suitability of Dipteryx alata (Fabaceae) in Brazilian Cerrado

description: ABSTRACT We experimentally evaluated how different temperatures affect germination of individual seedlings of Dipteryx alata, and estimated the impact of climate change on the species using ecological niche modeling. A total of 240 seeds were randomly distributed among three different temperature treatments (32 ºC, 36 ºC, and 40 ºC), and monitored for 35 days. We measured seven seed traits and estimated the ecological niche of D. alata using a consensus of four methods. The treatment with the highest temperature produced smaller and lighter seedlings. The consensus of ecological niche modeling indicated that are expected to reduce the areas with climates favorable for D. alata in future scenarios. Thus, our two results (experiment and ecological niche modeling) are concordant, and both indicate the impact of global warming on germination (initial stage of the plant) and potential geographic distribution. Moreover, in geographic context, our experiment and ecological niche modeling indicated that north, northwest and central regions of the “Cerrado” are predicted to have lower morphological traits of germination and loss climate favorable area, since these regions are predicted to have higher temperatures (nearly 40 ºC) in future climatic scenarios.

title: Clinical and epidemiological features of tuberculosis in children and adolescents

description: ABSTRACT Objective: To analyze the clinical and epidemiological features of tuberculosis in children and adolescents in an infectious diseases reference hospital. Method: A documental and retrospective study was carried out with 88 medical files in an infectious diseases reference hospital in the state of Ceará. Data were analyzed by univariate, bivariate and multivariate approaches. Results: It was found that, depending on the tuberculosis type, its manifestations may vary. The logistic regression model considered only pulmonary tuberculosis due to a number of observations and included female sex (95% CI: 1.4-16.3), weight loss (95% CI: 1.8-26.3), bacilloscopic screening (95% CI: 1.5-16.6) and sputum collected (95% CI: 1.4-19.4) as possible predictors. Conclusions: Children and adolescents present different manifestations of the disease depending on the tuberculosis type that affects them. Knowing the most common features of each condition could enhance early diagnosis and, consequently, result in adequate treatment and care.

title: A survey of whole-plant corn silages from Minas Gerais dairy farms

description: ABSTRACT Whole-plant corn silage (WPCS) is a commonly used forage for feeding dairy cattle in Brazil. The aim of this study was to evaluate on-farm ensilaging practices and the nutritional value, microbiology and fermentation profiles of WPCS from dairy farms in the south of the state of Minas Gerais, Brazil. Silages from 54 dairy farms located in nine cities were sampled and a questionnaire was distributed for completion to describe the herd profile and ensilage practices. Herd size ranged from 8 to 1,000 lactating cows, and 52 % of the farms had fewer than 50 cows in lactation. The majority of the farms cultivated hard endosperm texture hybrids (52 %) and used pull-type forage harvesters (87 %). Double-sided plastic was the most used form of silo sealing (56 %) and 28 % used inoculants. Lactic acid bacteria count was greater than 6.01 log CFU g–1 in 60 % of the samples, and the mean populations of enterobacteria and Bacillus spp. were 4.23 and 4.09 log CFU g–1, respectively. Silo size ranged from 100 to 250 m3 in 44 % of the farms, and the silage removal rate was below 15 cm of the face/d in 41 % of cases. Silage dry matter (DM) concentration was 33 ± 3 % of fresh matter, NDF concentration was 57 ± 7 % of the DM, and in vitro NDF digestibility was 35 ± 11 % of the NDF. Silages with high DM concentrations had large particle size, affecting the nutritional value and the fermentative pattern. Improvements in ensiling practices can potentially inhibit the growth of spoilage microorganisms and raise the nutritional value of silages.

title: Influence in the reproductive planning and the women's satisfaction with the discovery of being pregnant in the quality of prenatal care in Brazil

description: Abstract Objectives: to analyze the influence on reproductive planning and the women's satisfaction with the discovery of being pregnant in prenatal care characteristics. Methods: a cross-sectional and quantitative study was carried out between March and July 2018 at a low-risk maternity hospital in the Brazilian Northeast region. A total of 652 puerperal women were evaluated in an interview and by their prenatal care card. The Chi-square test and the Odds Ratio were used for statistical analysis. Results: the pregnancy planning was reported by 42% (n=274), and the women's satisfaction of being pregnant was 64.1% (n=418) of the interviewees. Reproductive planning was associated with early initiation of prenatal care (OR=2.48, CI95%=1.61-3.82) and the women received information about the referral maternity for childbirth (OR=1.44, CI95%=1.05-1.99). The women's satisfaction with their pregnancy was also associated with early initiation of prenatal care (OR=2.18; CI95%=1.47-3.25). It should be noted that the performance of six or more prenatal care consultations was less frequent among pregnant women who had not planned their pregnancy (OR=0.43, CI95%=0.27-0.66) and they felt unsatisfied with the discovery of being pregnant (OR=0.56; CI95%=0.37-0.84). Conclusions: Pregnancy planning and women's satisfaction with the discovery of being pregnant favors the performance of prenatal care with better indicators.

title: Assisted Reproductive Technologies in Latin America and Europe: a Comparative Analysis of Reported Databases for 2013

description: Abstract Objective To compare the Latin American and European assisted reproductive technology (ART) registries regarding data accessibility and quality, treatment utilization, effectiveness, safety, and quality of services. Methods We performed an ecological study using data from scientific publications of Latin American and European registries that report cycles initiated during 2013 (the most recent registries available until December of 2017). The summarized data are presented as frequencies, percentages, minimum-maximum values, and absolute numbers. Results Reporting clinics and cycle treatments were unevenly distributed between the participating countries for both registries, although access to ART is 15 times greater in Europe. In Latin America, individual services participate voluntarily reporting started cycles until cancellation, birth or miscarriage, while in Europe it varied among countries. It makes the data available from Latin America more uniform, although lesser representative when compared with European ones, given that reporting is compulsory formost countries. The cumulative live birth rate was better in Latin America. Female age, use of intracytoplasmic sperm injection (ICSI), cycles with transfer of ≥ 3 embryos, as well as multiple pregnancy rates were greater in the Latin American Register of Assisted Reproduction (RLA, in the Portuguese acronym). Assisted reproductive technology complications, such as ovarian hyperstimulation syndrome, hemorrhage, and infections were also higher in LatinAmerica, although they are extremely uncommon in both regions. Conclusion Both regions have points to improve in the quality of their reports. Latin America has produced a more uniform reporting, their clinical results are generally

title: Depression, self-concept, future expectations and hope of people with HIV

description: ABSTRACT Objective: To analyze conditions of depression, self-concept, future expectations and hope in people with HIV/AIDS. Method: Cross-sectional survey of 108 individuals living with HIV/AIDS, carried out in a reference hospital for the treatment of infectious diseases in Northeast Brazil. The following instruments were employed: sociodemographic data, and questionnaires for ascertaining participants’ emotions, including scales for self-concept, hope, depression (HAMD-D), and future expectations. Descriptive statistics using the following tests were performed: Mann–Whitney, Kruskal–Wallis, chi-square, and t-test—considered significant when p ≤ 0.05. Results: 31.5% presented mild depression and 21.3% presented moderate depression; 63% reported difficulty in obtaining decent employment; 52.8% considered life a failure; 52.8% felt worthless. Fear, guilt and loneliness influenced self-concept (p ≤ 0.05). Loneliness influenced hope (p ≤ 0.05). Conclusion: It is necessary to raise the attention of nursing professionals and healthcare managers to the importance of providing health services that consider the mental health of people with HIV/AIDS, contributing to treatment adherence and well-being.

title: Hydrogen Peroxide Electrogeneration by Gas Diffusion Electrode Modified With Tungsten Oxide Nanoparticles for Degradation of Orange II and Sunset Yellow FCF Azo Dyes

description: In this work, the gas diffusion electrode (GDE) cathode of Vulcan XC72 carbon modified with nanoparticles of WO2.72 (WO2.72 / Vulcan XC72) was used for H2O2 electrogeneration and degradation of 350 mL of Orange II (OII) and Sunset Yellow FCF (SY) azo dyes by electro-Fenton (EF) and photoelectro-Fenton (PEF) processes with different Fe2+ initial content (1.00, 0.50 and 0.25 mmol L-1). The WO2.72 / Vulcan XC72 GDE electrolyzed approximately 3 times more H2O2 than the Vulcan XC72 GDE. Decolorizations and mineralizations of the dye solutions were more efficient at higher concentrations of Fe2+. The decolorization decay showed pseudo-first-order kinetics. The most promising decolorization results obtained at processes of WO2.72 / Vulcan XC72 cathode combined with Pt anode (100% color removal of OII and SY at 30 and 20 min of electrolysis with 1.00 mmol L-1 Fe2+, respectively). The best mineralization achieved in trials of WO2.72 / Vulcan XC72 cathode combined with boron-doped diamond (BDD) anode (82% total organic carbon (TOC) removal of OII by PEF / 1.00 after 3 h and 90% TOC removal of SY by PEF / 0.50 after 4 h). It was found that SY decolorization was faster and mineralization showed a similar yield independent of oxidized dye.
