Weaknesses in the continuity of care for preterm infants discharged from the neonatal unit.

To identify weaknesses in the continuity of care for preterm infants discharged from a neonatal unit, based on the perspective of professionals in the family health strategy. Qualitative research, carried out with 16 professionals from four health regions in a capital city in the center-west of Brazil. Data collection took place from October to December 2020, through semi-structured, individual, and in-person interviews. Data underwent content analysis, supported by the concept of continuity of care. The analysis consisted of three categories: Challenges for care in the unit and referral to specialized services; weak interactions between the preterm baby's family and health professionals; Information: essential aspect for the connection between health professionals and the family of the preterm newborn. Health services are shown to be fragile in terms of the dimensions of continuity of care, contributing to the discontinuity of care for preterm children.

Botulismo em bovinos no Mato Grosso do Sul: histórico, situação atual e perspectivas

ABSTRACT: Botulism is a neuroparalytic disease caused by ingesting neurotoxins (BoNTs) produced by the anaerobic bacterium Clostridium botulinum. It is a significant cause of cattle mortality in Brazil. BoNTs block the release of acetylcholine at the neuromuscular synapses and cause muscle flaccidity. The diagnosis of botulism is challenging due to two main factors: the absence of macro and microscopic lesions and the difficulties inherent in laboratory tests considered the gold standard for botulism. Due to these difficulties, reviews of botulism diagnoses in Mato Grosso do Sul and extensively in the Center-West of Brazil became discrepant according to the diagnostic methodology used, making it difficult to correctly assess the disease’s prevalence, epidemiology, and clinical picture. This study aimed to review the diagnoses of botulism in cattle reported in Brazil, comparing the criteria used in each case. We studied the cause, the pathogenesis, clinical signs, and all the diagnosis methods applied to botulism. Based on the subject reviewed, we propose a diagnostic protocol based on standards adequate to the Brazilian circumstances. We also reviewed the critical diseases of cattle diseases to be included in the differential diagnosis of botulism.

Prevalence of inflammatory periodontal disease in patients attended in a university dental clinic – a retrospective analysis

OBJECTIVE: To estimate the prevalence of inflammatory periodontal disease (IPD) in individuals treated in a university dental clinic located in the Center-West of Brazil. METHODS: We performed a retrospective cross-sectional study with census sample. Previously collected data from dental records were tabulated and analyzed descriptively. RESULTS: 151 patients were included on the research. Approximately 60% presented gingivitis and 32.4% periodontitis. 85.4% showed high plaque index (>10%) and 31.7% declared not to use dental floss. 12% of the participants reported being diabetic and 17.2% were smokers. The prevalence of deep pockets was the worst periodontal condition found (15.2%). CONCLUSION: The prevalence of ILD found in this population was higher than the Brazilian national average. The results can be useful to support buccal and general health promotion strategies on public policies.

INFLUÊNCIAS DA ESFERA AFETIVO-RELACIONAL COM O PARCEIRO NO ENGRAVIDAR INTENCIONADO DE ADOLESCENTES

ABSTRACT Objective: to understand interconnected influences on adolescents’ intended pregnancy based on particularities of the affective-relational sphere with partners. Method: this is a qualitative-interpretive study, carried out with 16 pregnant adolescents living in a neighborhood with a low socioeconomic level in a capital in the center-west of Brazil. Data were collected in 2019 through in-depth interviews, with complementary use of self-portrait, relational map and photo-elicitation resources, subjected to thematic content analysis. Results: adolescents’ intention-action towards becoming pregnant was based on status assessment and romantic relationship quality with their partners in terms of marriage/union, bond-commitment, partnership-financial protection and good interaction-love. They expressed needs for emotional bonding and material security, psychological particularities of their stage of development, in addition to social representations built on the conjugal and loving relationship and being a man and a woman in the family. Connectedly, it reflected on social conditions and family relationships experienced as well as absorptions of the cultural ideal of romantic and gender love. Conclusion: in adolescents’ reproductive health, it is essential to consider the affective influences on being pregnant, without detaching them from their social and family insertions as well as their ways of exercising agency over their affective-sexual trajectories.

Ocorrência e avaliação de risco ecológicos de compostos farmaceuticamente ativos em pequenas bacias neotropicais, Brasil

Abstract: Aim The aim of our study was to evaluate the contamination levels of selected pharmaceutically active compounds (PAC) and their potential ecological threat to forested streams. Methods Samples of stream water were collected in the second largest city in Mato Grosso do Sul State in center-west of Brazil. Physicochemical parameters and concentrations of PAC were quantified in samples collected in six field campaigns. Ecological risk assessment (ERA) based on risk quotient (RQ) was performed based on the maximum measured concentration of PAC in water. Results Six pharmaceutical compounds were successfully quantified in the forested streams, namely caffeine, naproxen, diclofenac, estriol, estradiol and ethinylestradiol. From the point of view of ecological risk, ethinylestradiol (22,57), estradiol (1,46), diclofenac (16.99) and caffeine (5.30) can be considered as priorities PAC, as they present moderate to high risks to aquatic organisms and may also cause damage to the food chain. Conclusions This study provides valuable information to emphasize the importance of continuous monitoring of forested streams in the west central region of the country, as well as efforts to control the input of these micropollutants into watercourses.

Geographical distribution and monitoring of dengue in 141 municipalities in the center-west of Brazil

In fact, it appears that dengue is characterized as a disease that has relevance to public health in the country. For the year 2019, 1,544,987 cases of dengue could be reported, with the presence of 782 confirmed deaths. Regarding the interruption of dengue epidemic cycles, it was noted that measures associated with vector control have not been successful. This study aims to analyze the spatial distribution associated with dengue cases present in the municipalities of the state of Mato Grosso, from 2015 to 2018, in order to identify the municipalities that have the highest risk rates related to the presence of arbovirus. Gross and Smoothed Rates were used through the Local Empirical Bayesian method. In order to calculate these Bayesian rates, a neighborhood matrix was developed with the presence of the continuity criterion that removed the zero risk of dengue from this calculation, thus minimizing the effects associated with the random fluctuations present in the areas that were monitored. Of course, the SaTScan software was used to calculate the Relative Risk (RR), and it was found that in this spatial scan clusters of low, medium and high risks were identified, demonstrating statistically significant data. The use of statistical techniques and spatial analysis employed in the study expanded the more detailed examination of the risk of transmission in the monitored areas, contributing significantly to the formulation and planning of integrated prevention and control strategies aimed at monitoring the arbovirus present in the state of Mato Grosso.

Herbicides to ruzigrass suppression in intercropping with corn

Background The corn intercropping with Brachiaria ruziziensis has rapidly raised in South and Center-West of Brazil. However, the uncertainty about forage interference on corn yield has led growers to use herbicides to suppress ruzigrass. Objective Our objective was to evaluate sub-doses herbicides applied in different stages of ruzigrass to suppress the growth in an intercropping system with corn. Methods A greenhouse experiment was carried out to evaluate the forage intoxication by herbicides to select the best treatments. Subsequently, a [...]

Networks in the context of digital culture: technologies, coordinators, university teachers and students

This research aims to analyze networks of relations in the context of digital culture, focusing on the relationships among technologies, coordinators, university teachers, and students. It is qualitative research with virtual etnography approach, developed in a private university in the Center-West of Brazil, with the participation of 39 university teachers, 285 students and 7 coordinators, answering questionnaires and semi-structured interviews, and posting messages at Facebook, related to the digital culture and to the formative educational process. The results point to a context of mismatch between the comings and goings of university teachers, students and coordinators, seeking to appropriate the technologies in order to invent other ways of teaching and learning, in different times and spaces, individually and collaboratively, with openness to the innovation in a critical way.

Genetic polymorphism among natural populations of Anacardium humile A. ST-HIL

Abstract The genus Anacardium presents nine species, of these, three have sub-bush size, common in the Cerrado of the Center-West of Brazil. The objective of this work was to evaluate the genetic variability of the species, collected in eleven provenances, using RAPD markers. Genomic DNA from 122 accessions was extracted and amplified with 25 decamer primers. The results indicated polymorphism, ranging from 77.71% to 96.18%. The distribution of genetic diversity among and within populations shows that 27.14% of the variability is found between populations and 37.44% within the populations, suggesting the existence of genetic variability that may be related to the reproductive strategies adopted by the species throughout its evolution. The index of variation within the provenances (93.36%) was higher than the index found among populations (6.64%). Molecular analysis indicated that there is genetic divergence between and within the studied populations of Anacardium humile A. St. - Hill. The origin of Itajá-GO presented the highest genetic diversity, presenting the highest values of genetic diversity index, phenotypic diversity and higher percentage of polymorphic loci.

Systematics of Scelioninae (Hymenoptera, Platygastroidea): new synonymy, distribution, and species.

The genera Doddiella Kieffer, 1913 and Aratala Dodd, 1927 are treated as junior synonyms of of Aneuroscelio Kieffer, 1913 following study of the rediscovered holotype of the type species Aneuroscelio rufipes Kieffer, 1913 (syn. nov.). The nine species previously recognized in Doddiella are all transferred to Aneuroscelio (comb. nov.). Calliscelio schlingeri (Masner & Johnson) is recognized as a junior synonym of Calliscelio vitilevuensis (Fullaway) (syn. nov.). Huddlestonium exu Polaszek & Johnson is recorded from Kenya, significantly expanding its known range from West Africa (Côte d’Ivoire, São Tomé). A new species of the genus Tyrannoscelio Masner, Johnson & Arias-Penna, T. cerradensissp. nov, is described from Paraguay and the Center-West of Brazil (Mato Grosso). The depositories of the holotypes of five recently described are corrected.

Amazon Rubber, A Potential Yet to be Rediscovered

Natural rubber still has socioeconomic, environmental and technical importance, despite the production of several synthetic similar polymers in the last 70 years. The Amazon Rainforest, the genetic base of Hevea brasiliensis, harbors a great diversity of ecosystems that can result in differentiated latex and elastomer molecules, from trees of the same species or other species and varieties of laticifer plants. Even so, there is little research to compare latex and rubber properties produced from native trees and planted clones. In this work, rubber latex was collected from four locations in the Amazon, including the historical places of Boim and Belterra and the most cultivated clone in Brazil, the RRIM 600, from a hevea plantation in the Center-West of Brazil. The following colloid properties were determined: pH, viscosity, particle size, dry rubber content, total solids content, gel content, total lipids, and total proteins. The molecular weight and the main physical and mechanical properties of the rubbers were also determined. Some main results can be highlighted: the rubber sample from Acre, in the extreme Western part of the Amazon, presented the highest molecular weight, while the Belterra sample, from remaining plantations of the Ford Project in Amazon, showed the highest values for mechanical properties. On the other hand, the technical characteristics of the RRIM 600 clone are close to the results obtained for the Boim sample, in Para, of the micro-region from where Henry Wickham collected the 70,000 seeds in 1876, from which the species was internationally domesticated. The present work is one of the very few studies to have been carried out with latex and rubber of these ancient rubber trees.

Quality of Life of the Plastic Surgeon in the Midwest of Brazil.

The quality of life theme is much studied in the area of plastic surgery; however, there are few studies on the quality of life of plastic surgeons. The main aim of this study was to describe the quality of life of the plastic surgeon in Center-West of Brazil. A cross-sectional study was performed of plastic surgeons in the greater state of Goias, Center-West of Brazil, registered until January 2015. A sample with power of 80%, 115 surgeons from 163 WHOQOL-BREF, and a social-demographic and professional questionnaire were used as instruments. The data were compared between qualitative variables of the questionnaire and WHOQOL-BREF using the Mann-Whitney and Kruskal-Wallis tests. One hundred sixteen surgeons answered; for WHOQOL-BREF, domain statistics were as follows: physical, 57.85; psychological, 62.9; social, 74.13; and environment, 68.56. The higher scores in each domain were related: physical: monthly income higher than US$ 11,200, more than 10 years of experience, weekly work hours lower than 40, being an associate or full member, and more than 4 surgeries/week; psychological: man, married, and having only private patients; social: man, monthly income higher than US$15,000, more than 20 years of experience, and weekly work hours lower than 40; and environment: monthly income higher than US$15,000, more than 10 years of experience, weekly work hours lower than 60, and more than 4 surgeries/week. The study demonstrates that the youngest surgeon, with a duration of less than 10 years, has the worst quality of life.

Produção endodôntica no atendimento público odontológico do Centro-Oeste do Brasil

Pouco se sabe sobre o atendimento público odontológico no Centro-Oeste do Brasil, ainda menos sobre sua produção endodôntica. Esta produção é realizada principalmente nos Centros de Especialidades Odontológicas (CEO), referência pública para tratamento endodôntico, acessível na base de dados DATASUS. Foi objetivo deste estudo explorar a produção endodôntica nas capitais dos estados da Região Centro-Oeste e do Distrito Federal do Brasil. Este estudo retrospectivo transversal analisou a produção endodôntica destes municípios de janeiro de 2011 a dezembro de 2016. Os dados foram obtidos consultando as bases do Ministério da Saúde (DATASUS) e do Instituto Brasileiro de Geografia e Estatística (IBGE). Os valores foram comparados por análise de variância e os testes de Kolmogorov-Smirnov e Levene seguidos pelo teste post hoc de Tukey. O nível de significância foi definido em p<0,05. Dentre as cidades analisadas, Campo Grande teve a maior produção endodôntica por habitante, seguida de Cuiabá e Goiânia com produções similares, e Brasília. Os dentes com três ou mais canais radiculares apresentaram maior incidência de tratamento endodôntico comparados a dentes com um ou dois canais radiculares. A produção endodôntica dos CEO das capitais dos estados da Região Centro-Oeste e do Distrito Federal do Brasil foi proporcionalmente maior em Campo Grande e menor em Brasília. O tratamento endodôntico foi realizado preferencialmente nos dentes com três ou mais canais radiculares. As instituições de ensino devem estar atentas às mudanças para que seus egressos sejam formados em consonância com o perfil epidemiológico da população bem como com as políticas públicas de saúde.

Serological and molecular evaluation of parvovirus B19 (B19V) in blood donors from the Blood Center of Brasília, Brazil: focus on women of childbearing age

ABSTRACT Parvovirus B19 (B19V) can be transmitted by the respiratory route, vertically - from the mother to the fetus - and via blood transfusion or organ transplantation. Infection by transfusion of blood or blood products occurs due to the resistance of B19V to viral inactivation methods. Our study evaluated the presence of B19V deoxyribonucleic acid (DNA) and the prevalence of anti-B19V class G immunoglobulin (IgG) in women of childbearing age blood donors of the Federal District, Brazil. Our results demonstrated the absence of B19V DNA in these blood donors. However, the seroprevalence for anti-B19V IgG was observed in 60.7% of this population. This study provides important data of B19V circulation in the Center-West of Brazil.

Effect of Rice Husk Treatment with Hot Water on Mechanical Performance in Poly(hydroxybutyrate)/Rice Husk Biocomposite

The south and center-west of Brazil are agribusiness and rice production centers. Hence, after the rice processing, approximately 20% of the rice husk is residue that is discarded by the industry. In this sense, the aim of this research is to evaluate the influence of hot water treatment in the rice husk (RH) and then use it as reinforcement in polyhydroxybutyrate (PHB) matrix. PHB/RH composites with ratio of 90/10 and 80/20 were obtained by melt blending. Two groups of fibers were used, in nature rice hull (RHi) and treated (RHt). The FTIR results of the effluent showed the presence of C=O, C=C, CO, CH, OH groups and silicon. Additionally, indicating a low molecular weight compounds on the natural fiber that are soluble in water. The matrix and composites were characterized by their physical, chemical, mechanical and morphological properties. Tensile and impact tests results showed that all the composites had better performance in terms of mechanical properties related to the unreinforced matrix. There was good interfacial adhesion between fiber and matrix for all the composites, which was verified by SEM images, especially for reinforced composites with untreated rice husk.

A Preliminary Study about the Utilization of Cajueiro and Amescla for MDP Panels Production

The most commons woods used for production of medium density particleboard (MDP) are Eucalyptus and Pinus. The Cajueiro and Amescla wood are typical trees coming from the center-west of Brazil, from the States of Mato Grosso and Tocatins. These are medium density woods similar to Pinus sp, the Brazilian’s wood’s industries usually used these woods only as piece of wood for structures or furniture. The purpose of this research is to investigate, in a preliminary study, the possibility of MDP panel’s production using Cajueiro and Amescla wood species. The panels were produced under a pressure of 4 MPa for 10 minutes at 100°C, and it was produced a total of 12 MDP panels, 6 of Cajueiro and 6 of Amescla, with a thickness of 10mm, dimensions 250mm×250mm and 0.5 kg mass. For the bending modulus of elasticity, 2200 MPa were obtained for Cajueiro and 2700 MPa for Amescla, which are considered good values. The results can be considered satisfactory because it is a preliminary and unpublished study in the case of MDP panels manufactured with Cajueiro and Amescla wood species.

Assessment of the fatigue failure of an All Aluminium Alloy Cable (AAAC) for a 230kV transmission line in the Center-West of Brazil

Abstract The aim of this work was to conduct an evaluation on the causes for the premature fatigue failure of an AAAC 900 MCM conductor used in a 230 kV transmission line located at the Center-West of Brazil. Each phase of the line had a double cable configuration separated by vertical rigid spacer clamps. To carry out the analysis, vibration recorders were installed on the spacer clamps at two different positions in the span and fatigue tests on the cable were conducted. The Miner's rule was applied and the remaining life of the cable was estimated to be greater than 33 years. The fact that the actual life of the cable is much smaller than the estimated one was associated to the conjoint action of three factors: (i) the use of rigid spacer clamps between the two conductors; (ii) the choice of an AAAC conductor (whose fatigue resistance proved to be significantly less than that of an ACSR) and (iii) the existence of a high frequency laminar wind regime. To avoid new failures the rigid spacer clamps were uninstalled. This action drastically reduced vibration in the line so that life estimates increased for more than 100 years.

Impacts of sugarcane ethanol production in the Paranaiba basin water resources

This study evaluates the impacts of sugarcane cultivation for ethanol production on water availability in a watershed located in the Center-West of Brazil, using the water footprint (WF) indicator. We assessed i) the green, blue and gray WF of sugarcane produced in Paranaíba basin in baseline (year 2010) and GHG emission scenarios (year 2020) under rainfed and full irrigation conditions; ii) the green, blue and gray WF of sugarcane ethanol produced in Paranaíba basin in 2010, and iii) the impact of the water demand for different sugarcane plantation scenarios on the context of water availability. Differences between full irrigated and rainfed sugarcane growing conditions resulted in different crop evapotranspiration, yields and WFs. For baseline scenario the WF of sugarcane was evaluated around 142 m3 t−1 (full irrigation) and 151 m3 t−1 (rainfed). For GHG emission scenarios was around 137 m3 t−1 (full irrigation) and 139 m3 t−1 (rainfed), in scenario A2, and around 136 m3 t−1 (full irrigation) and 137 m3 t−1 (rainfed), in scenario B2. In this context irrigation has proved to be an important way to increase the sugarcane yield and reduce WFs. However water demands for full irrigated sugarcane destined for ethanol production showed different conditions of quantitative impairment of surface water resources in Paranaíba basin. The potential impacts may result in lack of adequate and equitable access to water, especially when the analysis considered the water availability for grants.
