MODELACIÓN POR COMPARACIÓN Y ACOPLAMIENTO MULTIMÉRICO DE LA PROTEÍNA EXTERIOR PEQUEÑA DE LA CÁPSIDE DEL BACTERIÓFAGO IME08
Authors: Ospina-Bedolla Maicol
Published: June 2020

The small outer capsid protein plays a stabilizing role in the viral assembly, adhering to the
capsid during the later stages of maturation. This protein acts as glue among adjacent
capsomers, protecting the virus against extreme changes. The small outer capsid protein of the
bacteriophage IME08 was modelled using structural protein homology. A trimeric protein
docking was developed with the best-scored model and important sites of the molecules
interfaces were identified. It was used the Swiss Model platform for developing the protein
structure. Reliability was assessed by the QMEAN, Verify3D and ERRAT indices. The quality of
the whole model was verified by Ramachandran plot and the trimerization model was
performed on the platform ClusPro 2.0 Protein-Protein Docking. The structure obtained has a
reliability estimator QMEANscore4 of 0.769, rating it as a suitable model. The Z-Score QMEAN
value was 0.133, showing that the obtained model is not different from the experimental
structures stored in PDB database. The estimators and the Ramachandran plot evaluated
positively the model. Finally we identified a loop between two secondary structures as an
important site of the interaction of small outer capsid proteins, indicating that from residues 35
to 41 are relevant in the trimerization process.

Published: June 2020

A transdisciplinary pilot study with Australia's livestock industries is bringing multiple stakeholders together as equal partners, to examine the complex problems around animal disease management. These problems include disease surveillance and on-farm biosecurity practices. The pilot groups are established in industries susceptible to foot and mouth disease, namely dairy and beef cattle, pork, sheep and goats. The Agricultural Innovation Systems framework is being evaluated to determine its effectiveness as a tool to improve partnerships between stakeholders. These stakeholders include livestock producers (farmers), private and government veterinarians, local council representatives, and industry personal including from saleyards and abattoirs. Stimulation of innovative solutions to issues arising from conflicting priorities and limited resources around animal disease management are also expected. Using a participatory communication approach, the impact of the pilot on trust and relationships is being evaluated. The sustainability of the Agricultural Innovation Systems approach to address complex issues around animal health management is also being assessed. The aim of the study is to strengthen Australia's preparedness for an emergency animal disease outbreak, such as Foot and Mouth Disease.

A FOTOPOLIMERIZAÇÃO DE COMPÓSITOS ODONTOLÓGICOS ALÉM DA POTÊNCIA LUMINOSA
Authors: Ribeiro de Magalhães Filho Thales
Published: June 2020

O objetivo deste estudo foi mostrar que a potência da luz das unidades de fotopolimerização (LED) não é a única ou a propriedade mais importante para uma polimerização satisfatória de compósitos dentários. A distribuição regular e o ângulo de incidência dos raios de luz também são igualmente responsáveis por uma polimerização mais completa e profunda. Esta revisão de literatura mostra que avançamos o suficiente na potência da luz emitida pelos LEDs, mas no que diz respeito à regularidade e ângulo dos raios emitidos, ainda temos muito a avançar. Novos compósitos com cargas reflexivas e preocupações com a diferença de índice de refração entre as cargas e a matriz são importantes para melhorar essa polimerização, mas os LEDs com vários comprimentos de onda podem complicar ainda mais a distribuição regular dos raios de luz emitidos. Dispositivos com diferentes LEDs emitindo raios de luz com diferentes comprimentos de onda não distribuem essas ondas no modo regular. Portanto, parte da restauração pode estar sub polimerizada, tornando-se menos resistente aos esforços mastigatórios e à infiltração. O estudo também relembra propostas de avaliação científica dessa distribuição regular e conclui que os LEDs modernos emitem raios de luz com grande potência e irradiância, mas ainda são irregulares na distribuição dos raios de luz emitidos.Palavras-chave: fotopolimerização, conprimento de onda, irradiância, resina composta.PHOTOPOLIMERIZATION OF DENTAL COMPOSITES BEYOND THE LIGHT POWER EMITED BY LED LIGHT CURING UNITSABSTRACT:            The objective of this study was to show that light power of light curing units (LCU) is not the only or the most important property for a satisfactory polymerization of dental composites. Regular distribution and angle of incidence of the light rays are also equally responsible for a fuller and deeper polymerization. This literature review shows that we advanced enough in the power of light emitted by LCUs, but as regards the regularity and angle of the emitted rays, we still have much to advance. New composites with reflective fillers and concerns about the difference of refractive index between the fillers and the matrixare important help to improve this polymerization, but LCUs with several wavelengths can further complicate the regular distribution of emitted light rays. Devices with different LEDs emitting light rays with different wavelengths does not distribute these waves in a regular mode. Therefore, part of the restoration can be under polymerized, becoming less resistant to masticatory efforts and infiltration as well. The study also recalls proposals for scientific evaluation of this regular distribution and concludes that modern LCUs emit light rays with great power and irradiance, but are still irregular in the distribution of emitted light rays.Keywords: photopolymerization, wavelength, Irradiance, composite.
A STUDY ON ABSOLUTE EULER TOTIENT SERIES SPACE AND CERTAIN MATRIX TRANSFORMATIONS
Authors: İLKHAN Merve , HAZAR GÜLEÇ G. Canan
Published: June 2020

Recently, many authors have focused on the studies related to sequence and series spaces. In the literature the simple and fundamental method is to construct new sequence and series spaces by means of the matrix domain of triangular matrices on the classical sequence spaces. Based on this approach, in this study, we introduce a new series space |ϕ_z |_p as the set of all series summable by absolute summability method |Φ,z_n |_p, where Φ=(ϕ_nk ) denotes Euler totient matrix, z=(z_n ) is a sequence of non-negative terms and p≥1. Also, we show that the series space |ϕ_z |_p is linearly isomorphic to the space of all p- absolutely summable sequences l_p for p≥1. Moreover, we determine some topological properties and α, β and γ-duals of this space and give Schauder basis for the space |ϕ_z |_p. Finally, we characterize the classes of the matrix operators from the space |ϕ_z |_p to the classical spaces l_∞,c,c_0,l_1 for 1≤p<∞ and vice versa.
A novel predictive model for estimation of cell voltage in electrochemical recovery of copper from brass: Application of gene expression programming

Published: June 2020

Regarding the high corrosion resistance of brass in sulfuric acid, its
leaching process is the most important step in hydrometallurgical recovery
of brass scraps. In this study, the electrochemical dissolution of brass
chips in sulfuric acid has been investigated. The electrochemical cell
voltage depends on various parameters. Regarding the complexity of
electrochemical dissolution, the system voltage could not be easily
predicted based on the operational parameters of the cell. So, it is
necessary to use modeling techniques to predict cell voltage. In this study,
139 leaching experiments were conducted under different conditions. Using
the experimental results and gene expression programming (GEP), parameters
such as acid concentration, current density, temperature and anode-cathode
distance were entered as the inputs and the voltage of the electrochemical
dissolution was predicted as the output. The results showed that GEP-based
model was capable of predicting the voltage of electrochemical dissolution
of brass alloy with correlation coefficient of 0.929 and root square mean
error (RSME) of 0.052. Based on the sensitivity analysis on the input and
output parameters, acid concentration and anode-cathode distance were the
most and least effective parameters, respectively. The modeling results
confirmed that the proposed model is a powerful tool in designing a
mathematical equation between the parameters of electrochemical dissolution
and the voltage induced by variation of these parameters.

Published: June 2020

Background/Aim. Although considered rare, gliomas cause morbidity and mortality disproportionate to their incidence. The aim of the study was to determine whether pre and post-therapeutic metric values, derived from the FDG PET/CT maximal standardized uptake value (SU-Vmax) and calculated ratios between tumor and normal brain tissue, may provide a predictive/prognostic biomarker information in estimating overall survival of glioblastoma patients. Methods. In 26 out of 31 patients with glioblastoma treated with standard Stupp protocol after maximal safe reductive surgery, we performed a baseline 18F-FDG PET/CT examination before commencing combined and concomitant chemotherapy/radiotherapy (pre-therapy FDG PET/CT) and a second examination three months after the therapy completion (post-therapy FDG PET/CT). Two-graded SUVmax values and a calculated ratio of uptake in tumor-to-normal-tissue (T/N ratio) value, divided into two grades by the calculated cut-off value, were measured in all patients at both pre- and post-therapy FDG PET/CT studies. Data sets were statistically analyzed by the Kaplan-Meier survival test and Log-rank was calculated, with the level of confidence determined at p < 0.05. Results. Pre-therapy FDG PET/CT two-grade T/N ratio value and both pre-and post-therapy FDG PET/CT derived two-grade SUVmax values had a strong predictive impact on overall survival of glioblastoma patients. Conclusion. Based on two-grade SUVmax and T/N ratio values assessment, FDG PET/CT could provide valuable predictive survival information in glioblastoma patients and serve as a selection tool for identifying patients at higher risk from worse outcomes and shorter survival time.

Published: June 2020

OBJECTIVE

Various organizations have highlighted the need to examine whether abdominal obesity cut points are appropriate for identification of cardiovascular risk among ethnic minority adults, particularly Hispanic/Latino adults living in Western societies. This study aimed 1) to establish optimal definitions for abdominal obesity among Hispanics/Latinos and 2) to determine the level of agreement between the presence of metabolic syndrome diagnosed by the current Joint Interim Statement (JIS) definition and an updated definition with optimal abdominal obesity cut points.

RESEARCH DESIGN AND METHODS

The sample included 16,289 adults who self-identified as Hispanic/Latino ages 18–74 years enrolled in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). Receiver operating characteristic curves were used to derive sensitivity and specificity values. The largest sum of sensitivity plus specificity was used to determine appropriate cut points.

RESULTS

Among U.S. Hispanic/Latino adults, waist circumference cut points of >102 cm in men (in line with current JIS criteria) and >97 cm (9 points higher than JIS criteria) in women provide optimal discrimination for cardiovascular risk as judged by the presence of coronary heart disease. When using these cut points to create an updated metabolic syndrome definition among women, we found disagreement between our updated definition and the current JIS criteria. The prevalence of the metabolic syndrome was overestimated by ∼5 percentage points among women based on JIS criteria in comparison with our definition.

CONCLUSIONS

Our results suggest that the current recommendations for waist circumference cut points may not be appropriate for U.S. Hispanic/Latino women.
Predicting 5- and 10-Year Mortality Risk in Older Adults With Diabetes
Authors: Griffith Kevin N. , Prentice Julia C. , Mohr David C. , Conlin Paul R.
Published: June 2020

OBJECTIVE

Several diabetes clinical practice guidelines suggest that treatment goals may be modified in older adults on the basis of comorbidities, complications, and life expectancy. The long-term benefits of treatment intensification may not outweigh short-term risks for patients with limited life expectancy. Because of the uncertainty of determining life expectancy for individual patients, we sought to develop and validate prognostic indices for mortality in older adults with diabetes.

RESEARCH DESIGN AND METHODS

We used a prevalence sample of veterans with diabetes who were aged ≥65 years on 1 January 2006 (N = 275,190). Administrative data were queried for potential predictors that included patient demographics, comorbidities, procedure codes, laboratory values and anthropomorphic measurements, medication history, and previous health service utilization. Logistic least absolute shrinkage and selection operator regressions were used to identify variables independently associated with mortality. The resulting odds ratios were then weighted to create prognostic indices of mortality over 5 and 10 years.

RESULTS

Thirty-seven predictors of mortality were identified: 4 demographic variables, prescriptions for insulin or sulfonylureas or blood pressure medications, 6 biomarkers, previous outpatient and inpatient utilization, and 22 comorbidities/procedures. The prognostic indices showed good discrimination, with C-statistics of 0.74 and 0.76 for 5- and 10-year mortality, respectively. The indices also demonstrated excellent agreement between observed outcome and predictions, with calibration slopes of 1.01 for both 5- and 10-year mortality.

CONCLUSIONS

Prognostic indices obtained from administrative data can predict 5- and 10-year mortality in older adults with diabetes. Such a tool may enable clinicians and patients to develop individualized treatment goals that balance risks and benefits of treatment intensification.
The reconstruction of physical education teachers: A critical discourse analysis of regulative texts
Authors: Porsanger Lise
Published: June 2020

In 2008, the Norwegian Directorate for Education and Training implemented a new circular with directives for water activities in schools and with a call for testing teachers’ water competence. This circular seems to align with international school safety policies, where additional regulations and safety guidelines are put into practice in school programs such as physical education. Despite this, studies that have applied a critical discourse perspective on regulative texts in physical education seem scarce. The purpose of this article is to examine how teachers’ risk and safety management in physical education is constructed in five regulative documents governing primary and secondary schools in Norway. Norman Fairclough’s critical discourse methodology has been applied to conduct a linguistic and contextual analysis of language. The analysis seems to reveal a discourse that challenge teachers’ autonomy and position. Because the discourse can appear to be neutral and imperative, it might be taken for granted in the field. The entrancement of a controller in examining teachers’ water competence seems to reflect ideals of revision and central control. This article therefore contributes to the understanding of regulative discourses and their power, in education and physical education.

Published: June 2020

According to the recent WHO data, 39 million people in the world are blind. In developing countries cornea diseases are the second most common cause of blindness. Cornea transplantation remains the only radical method to regain lost vision for many blind people around the world. However, according to literature reports, cadaveric donor corneas pose a potential risk of herpes virus transmission to the recipient during penetrating keratoplasty. It is known that herpes simplex virus-1 persisting in the donor cornea can adversely affect graft survival up to causing the graft failure reaction. The latent herpes simplex virus may be reactivated by a number of factors, most of them occurring with penetrating keratoplasty. One of these factors is immunosuppressive therapy, an essential element of the pharmacological graft protection. Antiviral agents are strongly recommended in order to inhibit the replicating herpes simplex virus in the cornea graft. The most common antiviral agents are interferons with their inducers and acyclic nucleosides. Viral decontamination during cornea storage would prevent the donor-to-recipient transmission of herpes simplex virus in relation to keratoplasty.

Authors:   Diplomatic Academy of the Ministry  of Foreign Affairs of the Russian Federation, Melikyan Gevork Gamletovich
Published: June 2020

The Collective Security Treaty was signed in Tash-kent 28 years ago, on May 15, 1992, by parties who were the new sovereign states formed after the col-lapse of the Soviet Union: Russia, Armenia, Kazakh-stan, Kyrgyzstan, Uzbekistan, and Tajikistan. A year later, the mentioned Treaty was signed by Belarus, Georgia and Azerbaijan. A decade later, the format of the Treaty was transformed and led to the crea-tion of the Collective Security Treaty Organization – CSTO, the charter of which was signed on October 7, 2002. Nowadays, the CSTO member states are Russia, Armenia, Belarus, Kazakhstan, Kyrgyzstan and Tajikistan, which have distinct features of secu-rity architecture. The role and the place of the CSTO in building a regional security system in the context of a transforming post-Soviet space are impacted by a number of different factors.

Este artigo analisa a importância da Ferrovia Norte-Sul (FNS) para o desenvolvimento econômico dos municípios de Açailândia (MA) e Porto Nacional (TO). Assim, aborda a relevância do modal ferroviário para o país, a privatização de trechos ferroviários em funcionamento, a projeção do transporte de cargas para os próximos anos e seus impactos territoriais. Ademais, é demonstrado como os investimentos das concessionárias cumprem papel significativo nesse processo, uma vez que a construção da FNS esteve, por diversos períodos, estagnada por falta de gestão pública dos recursos. Demonstra, ainda, como a gestão pública/privada se coloca como uma alternativa para a consolidação das ferrovias brasileiras, contribuindo para interligar e intensificar a relação econômica entre municípios e regiões brasileiras com o mercado mundial. Por meio de pesquisas bibliográficas e documentais constata que houve melhorias na economia dos municípios de Açailândia (MA) e Porto Nacional (TO), locais em que se encontram os principais pátios ferroviários da FNS em funcionamento.

Esta pesquisa tem o objetivo de avaliar a interação da UFJF com a sociedade, por meio da análise das interações de seus Grupos de Pesquisa com empresas, poder público e organizações da sociedade civil. A revisão da literatura focou nos modelos da Triple Helix e da Hélice Quádrupla, bem como nas barreiras à interação da universidade com a sociedade. O método utilizado foi a pesquisa de campo, por meio de survey, realizada no mês de outubro de 2019 com a participação de 74 Grupos de Pesquisa da UFJF. A análise dos dados foi realizada por meio estatística descritiva simples e os resultados mais relevantes indicam que as principais interações da UFJF estão relacionadas com outras instituições de ensino e pesquisa, no Brasil e no exterior, seguida de ações de interação com organizações da sociedade civil e com o poder público. Verifica-se que ainda é incipiente a interação com empresas. O ponto positivo é que a resistência de interagir com estas organizações representa menos de 25% dos respondentes, o que propicia a possibilidade de ampliação destas interações.

Purpose. The research goal comprises primary analysis of CT examinations results and their interpretation by comparing with the data already available in the literature.

Material and methods. During the period from April 17, 2020 to May 18, 2020, 830 chest CT scans were performed and results of 123 CDs with CT scans made by other institutions were interpreted. Follow-up examinations were carried out every 3–4 days or when clinical presentation changed. At the primary stage, we have analysed in a more detail way a group of 69 patients, who were diagnosed with CT-3 or CT-4 volume of lung damage at least once during hospitalization. The patients underwent PCR analysis three times during hospitalization. Among 69 patients, 34 patients had a positive PCR test at least once, the remaining 35 patients had a clinic, corresponding with this disease.

Results. At the initial examination, ground-glass opacity prevailed, as it was observed in 44 cases (64%), and lung tissue consolidation was observed in 25 cases (36%) in a group of 69 patients. When comparing the two groups, the average age of the patients with consolidation changes was statistically significantly lower than one of the group where ground-glass opacity prevailed – 51.7 and 59.4 years, respectively (p = 0.01) In the group of patients with pulmonary tissue consolidation, there were fewer concomitant diseases, fatal outcomes, positive PCR test results, a shorter hospitalization period, and fewer cases of tocilizumab administration were noted. At the initial examination the average percentage of pulmonary parenchyma involvement in the group of patients with lung tissue consolidation was higher (63.3%; p = 0.04), follow-up examinations showed c statistically significantly lower average values of the increase in the percentage of involvement of the parenchyma, which acquired negative values after the third CT scan (8.3 after the 2nd CT and −5.2 after the 3rd CT versus 18.5 and 3 in the GGO glass group; p = 0.02 and 0.03, respectively). No visible differences in CT between the period from the onset of the disease and the predominant symptom in CT were revealed. Meanwhile, on the 5th day (the day of the check-up CT examination) the largest number of patients was determined in both groups.

Conclusion. An analysis of our experience during the first month of operation of Covid-19 Hospital is presented. According to our data, the appearance of consolidation at the initial CT examination is probably not related to the period, when the disease has been in progress, and may be associated with a more favorable course of the process.

Aim: to explore functional connectivity of the normal brain during Stroop test modification and new suggested counting test performance.

Materials and methods. Data were acquired from 18 healthy volunteers who underwent fMRI examination on 3T scanner with Stroop test modification and new suggested counting test used as block paradigms.

Results. Functional connectivity analysis showed involvement of similar regions but with different distribution of positive correlations between them: interhemispheric significant positive correlations during Stroop test modification performance were found between anterior insular cortex, interhemispheric significant positive correlations during counting test performance were found between dorsolateral prefrontal cortices bilaterally and inferior parietal cortices bilaterally. Different distribution of significant correlations could be due to specificity of tasks. Comparative analysis showed significantly higher positive correlations with occipital cortex during Stroop test performance.

Conclusions. Received data allow alternative use of the abovementioned paradigms for executive functions investigation, with preference for counting test paradigm in patients with vision disturbances.

Published: June 2020

Aim. This publication is devoted to a brief review of the unresolved questions of medical imaging and treatment of COVID-19.

Materials and methods. The analysis of publications for the first quarter of 2020 on radiation diagnosis and treatment of COVID-19 with an emphasis on morpho-radiological comparisons was performed.

Results. It was established that CT can be used for the initial “sorting” of patients in determining the need and conditions of hospitalization, but in the future, often leads to disagreement among pulmonologists and radiologists in assessing the dynamics of the development of the disease. In most patients with COVID-19, the pathomorphological and radiological patterns indicate the formation of the acute phase of diffuse alveolar damage, transforming into organizing pneumonia with typical CT manifestations. However, to date there are no established opinions on the management of patients with corresponding lung lesions.

Conclusion. The literature data on the peculiarities of the pathomorphological and radiological patterns of COVID-19 COVID-19 justify the advisability of using corticosteroids in the treatment of this disease.

Purpose of the study. To evaluate the practical significance of MRI in the primary diagnosis of inflammatory lung diseases, as well as in follow-up control of treatment, also in comparison with the results of CT of the chest.

Material and Methods. In 25 patients with acute pneumonia, six of them with acute myocardial infarction developed as complication of it, the MRI of the chest organs was performed in T1 - and T2-weighted (-w.) modes, also with fat signal suppression, with slice thickness of 2.5 to 5 mm, in a matrix of 256 × 256 or 256 ×392 pixels, with a scanning field of view as large as 40 x 40 cm. In T1-w. mode TR = 390–650 ms, TE = 10–15 ms. When T2-w. scanning, respectively, TR = 2900 -4000 ms, TE = 20–25 ms. Paramagnetic contrast enhancement was also carried out in 16 of 24 patients, at a dosage of 0.1 mmol/kg of body weight. Post-contrast images were acquired 12-17 minutes after the introduction of paramagnetic agent. In 17 out of 25 of our patients, chest CT was also performed.

Results. The minimal cross-dimension of focal inflammatory lesions for community-acquired pneumonia, imaged with MRI chest scanning was as little as 9 х 21 mm. The dimensions of lung lesion obtained from the MRI scanning did correlate significantly with results of the CT (r = 0.96, p < 0.001). Also MRI of the lung did prove the successful cure of pneumonia. Also in six cases the MRI verified the acute myocardial infarction occurred as complication of severe pneumonia. Based on the results of MRI of the lungs and chest, the treatment strategy was supplemented in 16 cases and significantly changed in 9 cases.

Conclusion. MRI of the lungs employing the T1- and T2-weighted protocols with fat suppression, diffusionweighted imaging and use of contrast enhancement delivers highly efficient technique of imaging of nodal, segment and lobe inflammation. MRI of the chest should be reasonably employed for diagnosis and follow-up of treatment in hospitals and diagnostic units possessing high- and middle-field MRI scanners able toacquire the images in breath-synchronised mode.

AN ONLINE RESOURCE HUB FOR ENGINEERING FACULTY: PROVIDING PRACTICAL INFORMATION AND SUPPORT FOR OUTCOMES-BASED EDUCATION
Authors: Parker A.M. , Dyck N. , Carey J. P.
Published: June 2020

Faculty resistance toward outcomes-based education (OBE) can be sorted into two categories— lack of understanding and lack of resources—and can be addressed by leadership through increased education and communication. With this in mind, the Faculty of Engineering at the University of Alberta has created an online OBE Resource Hub on its faculty intranet, guided by the question, “What kinds of education and communication do faculty require to gain knowledge and acceptance of OBE, and therefore be engaged and motivated in the process?” Artifacts on the ever-growing site include theoretical and practical information in the form of articles, tipsheets, videos, and external links. This article showcases the site, since an initiative of this nature might be of interest to other post-secondary faculties working toward OBE.
CURRICULUM RENEWAL FOR BETTER DESIGN-RELATED STUDENT OUTCOMES IN SECOND-YEAR CHEMICAL AND BIOLOGICAL ENGINEERING
Authors: Potvin Gabriel , Verrett Jonathan
Published: June 2020

The Department of Chemical and Biological Engineering at UBC is currently undergoing a major curriculum renewal with the aim of modernizing the two undergraduate programs it offers to better prepare students for increasingly diverse industries. Part of this initiative aims to introduce design earlier and integrate it throughout the programs.          At the core of the new 2nd year curriculum are two new courses: CHBE 220 and 221 – Fundamentals of Chemical and Biological Engineering I/II. CHBE 220 is taken in term 1 and replaces a previous classically-structured physical chemistry course and an introductory seminar on process technology. It focuses on basic chemical process design and analysis, drawing from thermodynamics and kinetics as needed to support design topics. CHBE 221, offered in term 2, replaces the previous introductory cell biology course, and focuses on industrial microbiology and bioprocess design, drawing from cell and molecular biology and physical chemistry as needed to support design tasks. Both courses include substantial term-spanning design projects.       This paper outlines the content and structure of both courses and their place in the updated curriculum. It describes the integrated design projects and other course deliverables. Recommendations for future iterations of the courses are also presented.

Published: June 2020

O objetivo deste artigo foi avaliar as ofertas de estágio para o curso de administração pública no município de Araraquara. Esta avaliação foi guiada por quatro dimensões analíticas, que se entrelaçam e interferem diretamente na oferta de vagas para o estágio e na dinâmica de sua execução. Nota-se que esta avaliação foi embasada em pesquisas com dados secundários disponíveis na Fundação SEADE, no Relatório Anual de Informações Sociais, no IBGE, no portal do curso de Administração Pública da Universidade Estadual Paulista e no portal da prefeitura municipal de Araraquara. Constatou-se que o município apresenta elevado potencial para geração de vagas de estágio para o curso de Administração Pública no município. Contudo, apresenta uma competitividade, em termos de potencial para gerar vagas, maior que os outros municípios que ofertam cursos no “Campo de Públicas”. Nota-se que há, proporcionalmente, um número menor de empresas com CNPJ ativo, logo os estudantes concorrem em um número maior por uma possível vaga.
Factors that Influence the Dissemination and Implementation of a School Health Policy

Published: June 2020

The policy on school health is ineffectively disseminated and poorly implemented in many contexts. The purpose of this study was to explore and describe the factors that influence the dissemination and implementation of a policy on school health in Bayelsa state in southern Nigeria. A qualitative approach (using an exploratory, descriptive and contextual research design) was used to achieve the aim of the study. Non-probability purposive sampling was used to select 24 participants for the study. Semi-structured individual interviews and an Olympus VN-7800 audio tape were used to collect data. The data were analysed concurrently using line-by-line the six inductive steps of a thematic analysis as well as Atlas ti version 8.0 to ensure consistency of the findings. The results show that bureaucracy, ineffective monitoring and evaluation, insufficient financial support, political interference, lack of equity of service delivery, poor working conditions, ineffective communication, and lack of knowledge and awareness are perceived as barriers to such a policy. Accessibility to policy documents, collaborative partnership, existing school health programmes, and competent and willing personnel are perceived as positive factors for the dissemination and implementation of such a policy. This study would contribute towards the improvement of school health and educational practices if the findings and recommendations are implemented appropriately.

Aim. Assessment of methods for prolonging gestation after an extra-preterm premature rupture of membranes (PROM) in a patient with abnormal invasive placenta and the efficacy of a multidisciplinary approach for treatment of a combined obstetric pathology in a tertiary perinatal centre.

Results. A clinical case is reported of PROM at 22+6 weeks’ gestation in a patient with two caesarean scars on the uterus and abnormal invasive placenta. In a tertiary perinatal centre, pregnancy was prolonged to 36+3 weeks’ term. The period between PROM and delivery was 96 days. A planned caesarean section and metroplasty were performed in the setting of temporary balloon occlusion of common iliac arteries. Blood loss was 75 mL/kg. Placenta increta without chorioamnionitis was confirmed histologically. The patient stayed in the intensive care unit for two days and was discharged home on the 8th day. The newborn was assigned the Apgar score of 6/6. For two days, ventilatory support was rendered in a neonatal intensive care unit. The newborn was diagnosed with congenital pneumonia, the first-degree hypoxic-ischemic damage of the central nervous system and transferred to the second phase of nursing.

Conclusions. A multidisciplinary approach and high technology facilities in the setting of a tertiary perinatal centre allow to reduce perinatal losses and provide high-quality care to patients with an increased risk of massive blood loss with the capacity to manage organ-preserving operative delivery with full rehabilitation in the postoperative period.
