Abstract Introduction: Pediatric extreme hydrocephalus (PEH) is a complex condition with uncertain prognostic outcomes. Objectives: In this study, we analyze the long-term change in cerebral parenchymal thickness of pediatric patients with extreme hydrocephalus after shunting. Methods: A retrospective observational study was conducted on patients with PEH treated at the General Hospital of Mexico from 2009 to 2016. Cerebral parenchymal thickness was measured in computed tomography studies before surgical intervention, at 5 months, and 4 years post-surgery. The average change in thickness in millimeters was analyzed, and its normalized value was assessed using the Wilcoxon test and the R2 of a linear function. Results: Twelve patients, including 5 females and 7 males, were studied. Nine cases were congenital, while the remaining 3 cases were 6 months, 7, and 10-years-old. At 5.2 months PostOp., patients showed an average increase of 160% in cerebral parenchymal thickness, which increased to 270% at 4.3 years. However, 4 cases (33.3%) had an increase of < 10% from the original thickness. One patient at 4.3 years exhibited a 594% increase compared to the baseline. In the congenital cases, pre-operative thickness had a good correlation (R2 = 0.70) with post-operative thickness, but pre-operative age of patients did not correlate with post-operative thickness (R2 = 0.03). Conclusions: In this study, 3 out of 12 cases of PEH showed a long-term increase of > 200% compared to preoperative thickness. Even in cases of extreme hydrocephalus, significant long-term improvement can occur. Rapid treatment of these cases is crucial to increase the likelihood of improvement.

Abstract This article addresses the world of healthcare work, especially in the Brazilian Unified Healthcare System (SUS) in the context of the COVID-19 pandemic in Brazil. This study used data from the following surveys: “Working conditions of health professionals in the context of COVID-19 in Brazil” and “The Invisible health workers: working conditions and mental health in the context of COVID-19 in Brazil”. Data analysis proves that the pandemic highlighted existing structural problems within SUS, involving the issue of healthcare workforce (HWF) management, which can be interpreted as another reflection of the socioeconomic inequalities that already exist in the country. This article highlights: the reduced provision of permanent education, the regulation of hybrid care, precariousness, a lack of protection in the work environment, as well as fragile biosecurity leading to tragic rates of illness and death of health workers. Our study concludes by showing the importance of formulating public policies in the scope of education and work management in SUS that ensure the discussion on hybrid care as a new way of acting without losing quality, together with the need to review issues related to permanent education, protection, valuation, and reduction of inequalities pointed out among the professional contingents analyzed in this article.

Abstract This in vitro study compared the antimicrobial efficacy of 2.5% sodium hypochlorite (NaOCl) and 8 µg/mL ozonated water agitated by passive ultrasonic irrigation (PUI) or PUI combined with EndoActivator (EA) against mature multispecies biofilm. One hundred and five oval-shaped mandibular premolars were instrumented, sterilized, and inoculated with Enterococcus faecalis, Candida albicans, and Staphylococcus aureus, divided into: control group - saline; O3 group - ozonated water; O3 PUI group - ozonated water with PUI agitation; O3 PUI+EA group - ozonated water with PUI+EA agitation; NaOCl group - NaOCl; NaOCl PUI group - NaOCl with PUI agitation; and NaOCl PUI+EA group - NaOCl with PUI+EA agitation. Microbiological samples were collected before (S1) and after (S2) the disinfection procedures and the data were statistically analyzed using the Kruskal-Wallis test. In the culture method, there was significant disinfection in the O3 PUI+EA, NaOCl, NaOCl PUI, and NaOCl PUI+EA groups (p˂0.05). The combination of NaOCl with PUI+EA reduced microbial counts to zero (p˂0.05). In the qPCR method, there was a significant reduction in the total count of viable microorganisms in the O3 PUI, O3 PUI+EA, NaOCl, NaOCl PUI, and NaOCl PUI+EA groups (p˂0.05). It can be concluded that 2.5% NaOCl with and without agitation, as well as 8 µg/mL ozonated water with its action enhanced by the agitation techniques, were effective in root canal disinfection, and their antimicrobial efficacy is related to the microorganisms present in the biofilm. 25 2 5 2.5 (NaOCl µgmL µg mL (PUI EA (EA biofilm ovalshaped oval shaped instrumented sterilized faecalis albicans aureus into saline O PUIEA S1 S (S1 S2 (S2 KruskalWallis Kruskal Wallis test method p˂0.05. p005 p p˂0.05 . 0 05 (p˂0.05) techniques 2.

RESUMO É importante avaliar as propriedades da superficie do esmalte após a aplicagao da ozonioterapia para clareamento, para garantir que o efeito clareadorproporcione condigoes adequadaspara um substrato dentário higido. Objetivo: O objetivo deste estudo in vitro foi avaliar os efeitos de um tratamento clareador com peróxido de carbamida (PC) a 10%, associado ou nao ao ozonio (O), na microdureza, rugosidade e micromorfologia da superficie do esmalte. Materials e Método: Blocos de esmalte bovino foram aplainados e distribuidos entre tres grupos de tratamento clareador (n=10): PC - 1 hora por dia/14 dias (Opalescence PF 10%/ Ultradent); O - 1 hora por dia a cada 3 dias/3 sessoes (Medplus VPhilozon, 60 mcg/mL e fluxo de oxigenio de 1 L/min); e PCO - CP com O, 1 hora por dia a cada 3 dias/3 sessoes. A microdureza (Knoop), a rugosidade (Ra) e a micromorfologia da superficie do esmalte avaliada por microscopia eletronica de varredura (aumento de 5.000x) foram analisadas antes e após os tratamentos. Resultados: ANOVA e teste de Tukey-Kramer mostraram que O e PCO mantiveram os valores de microdureza do esmalte ao final do tratamento (p=0,0087), enquanto PC promoveu diminuigao da microdureza. O promoveu maiores valores de microdureza do esmalte do que os outros grupos ao final do tratamento (p=0,0169). Modelos lineares generalizados mistos para medidas repetidas no tempo indicaram um aumento na rugosidade da superficie para PC, levando a maior rugosidade do esmalte ao final do tratamento, em comparagao com PCO ou O (p=0,0003). PC apresentou pequenas irregularidades na micromorfologia do esmalte após o tratamento clareador. O, com ou sem PC, manteve as propriedades mecánicas e fisicas de microdureza e micromorfologia da superficie do esmalte, e manteve ou reduziu a rugosidade da superficie, em comparagao com o tratamento clareador a base de PC aplicado em moldeira convencional. Conclusoes: O tratamento com peróxido de carbamida a 10% para uso em moldeiras promoveu maiores alteragoes nas propriedades de superficie do esmalte do que aquelas observadas nos tratamentos com ozonio e com peróxido de carbamida ozonizado a 10% para uso em consultório.

ABSTRACT After ozone therapy for bleaching, it is important to evalúate enamel surface properties, to ensure that bleaching provides adequate conditions for sound dental substrate. Aim: The aim of this in vitro study was to evaluate the effects of a bleaching treatment with 10% carbamide peroxide (CP), with or without ozone (O), on the microhardness, roughness and micromorphology of the enamel surface. Materials and Method: Bovine enamel blocks were planed and distributed among the following three bleaching treatment groups (n=10): CP - 1 hour per day/14 days (Opalescence PF 10%/ Ultradent); O - 1 hour per day every 3 days/3 sessions (Medplus VPhilozon, 60 mcg/mL and oxygen flow rate of 1 L/min); and OCP - CP with O, 1 hour per day every 3 days/3 sessions. Enamel surface microhardness (Knoop), roughness (Ra), and micromorphology by scanning electron microscopy (5,000x magnificaron) were determined before and after the treatments. Results: ANOVA and Tukey-Kramer’s test showed that enamel microhardness remained unchanged by treatment with O and OCP (p=0.0087), but decreased by treatment with CP. Treatment with O promoted higher enamel microhardness than the other groups (p=0.0169). Generalized linear mixed models for repeated measures over time indicated treatment with CP increased enamel roughness more than OCP or O (p=0.0003). CP produced slight irregularities in enamel micromorphology after the whitening treatment. O, with or without CP, maintained the mechanical and physical properties of microhardness and enamel surface micromorphology, and either maintained or reduced surface roughness, compared to the conventional tray-delivered CP bleaching treatment. Conclusions: Treatment with 10% carbamide peroxide in trays promoted greater changes in enamel surface properties than treatments with ozone and with 10% ozonized carbamide peroxide in the office.

Abstract This research analyzes the efficiency of 24 departments of Colombia in the use of their resources to achieve the objective of the national educational programs, during the 2007-2018 period. The efficiency assessment was carried out through the Data Envelope Analysis (DEA), designing three models oriented to output and structured with variable returns to scale. The results of the three shows that only the departments of Bogota D.C., Antioquia, and Quindio efficiently used their teaching staff and educational facilities to increase literacy, enrollment, and urban-rural equity. Therefore, it is advisable to develop public policies aimed at strengthening the education sector, and thus contribute to the well-being of society.

Resumo A atenção especializada do sistema público de saúde brasileiro é crítica e subfinanciada. Poucos estudos avaliaram o planejamento da atenção secundária em um nível estratégico, portanto ainda há questões em aberto a serem examinadas. Este estudo objetiva determinar a localização de centros médicos e a quantidade de equipamentos com base em um processo de otimização em duas etapas para atender a população. Balanceamos decisões conflitantes de propensão dos médicos em trabalharem em metrópoles e de pacientes em mudarem o mínimo de seus municípios para fornecer a localização dos centros médicos, e equipamentos a esses locais e as horas adicionais de especialistas para atender aos padrões oficiais de demanda. Para a demanda restante, a segunda etapa do modelo de otimização sugere a aquisição de equipamento para os centros médicos eleitos, para atender às necessidades. A localização proposta das unidades de atendimento secundário abrange 834 municípios, correspondendo a 97,77% do estado, com um deslocamento médio de pacientes de 58,73 km (IC95%: 56,18 km - 61,28 km). Em geral, 39 das 77 regiões de saúde devem contratar horas adicionais de especialidades médicas. Pediatria e ginecologia representam a maior lacuna.

Abstract The specialized care level of the public Brazilian national health system is critical and chronically underfunded. Few studies have evaluated public secondary care planning on a strategic level, so there are open issues yet to examine. This study aims at locating medical centers and sizing equipment based on a two-step optimization process to meet the population’s needs. The models consider physicians’ propensity for working on a metropolis and the patients’ choice on moving the least from their municipalities, therefore, conflicting decisions. The models provide the location of medical centers, the assignment of equipment to such locations, and the additional hours of specialists required to meet official standards of demand. Available equipment with idle capacity should partly satisfy the requirement for exams within the current infrastructure. For the remaining uncovered demand, the second step of the optimization model suggests the acquisition of additional equipment for the elected medical centers to meet established needs. The proposed location of secondary care facilities covers 834 municipalities, corresponding to 97.77% of the estate, with an average patient displacement of 58.73 km (CI95%: 56.18 km - 61.28 km). In general, 39 out of 77 health regions should hire additional hours of medical specialties. Pediatrics and gynecology represent the major gap.

Abstract This research aims to analyze the determinants of Foreign Direct Investment (FDI) in 14 APEC economies during the period 1990-2019. For this purpose and starting from the segmentation of the economies into homogeneous groups of analysis, two econometric panel data models were developed. The results show that the flow of FDI in Group 1 (Australia, Canada, China, the United States, Hong Kong, Japan, and Russia) was determined by wages, high technology exports, and the level of spending of nations. While in the case of Group 2 (Chile, South Korea, Indonesia, Malaysia, Mexico, Singapore, and Thailand) it was public spending on education and value-added per worker in industry that determined it.

Resumen Esta investigación tiene como objetivo analizar los determinantes de la inversión extranjera directa (IED) en 14 economías del APEC durante el periodo 1990-2019. Para tal fin, y partiendo de la segmentación de las economías en grupos homogéneos de análisis se elaboraron dos modelos econométricos de datos panel. Los resultados del estudio denotan que el flujo de IED en las economías del grupo 1 (Australia, Canadá, China, Estados Unidos, Hong Kong, Japón y Rusia) estuvo determinado por las remuneraciones al trabajo, las exportaciones de alta tecnología y el nivel de gasto de las naciones. Mientras que en el caso del grupo 2 (Chile, Corea del Sur, Indonesia, Malasia, México, Singapur y Tailandia) fueron el gasto público en educación y el valor agregado por trabajador en la industria los factores que la determinaron.

ABSTRACT BACKGROUND: The fragility of healthcare systems worldwide had not been exposed by any pandemic until now. The lack of integrated methods for bed capacity planning compromises the effectiveness of public and private hospitals’ services. OBJECTIVES: To estimate the impact of the COVID-19 pandemic on the provision of intensive care unit and clinical beds for Brazilian states, using an integrated model. DESIGN AND SETTING: Experimental study applying healthcare informatics to data on COVID-19 cases from the official electronic platform of the Brazilian Ministry of Health. METHODS: A predictive model based on the historical records of Brazilian states was developed to estimate the need for hospital beds during the COVID-19 pandemic. RESULTS: The proposed model projected in advance that there was a lack of 22,771 hospital beds for Brazilian states, of which 38.95% were ICU beds, and 61.05% were clinical beds. CONCLUSIONS: The proposed approach provides valuable information to help hospital managers anticipate actions for improving healthcare system capacity.

Resumo Embora o consumo de açaí (Euterpe oleracea) seja há tempos um importante componente da dieta dos povos amazônicos, o açaizeiro tem recentemente atraído tanto o interesse econômico quanto científico devido à presença de urna vasta gama de compostos bioativos encontrados no pericarpo de seus frutos. As sementes de açaí representam o principal subproduto após a extração da polpa e podem ser potencialmente utilizadas para a produção de etanol, mas esse processo é dificultado pelo conhecimento limitado sobre a biología das sementes, sua composição química e a deposição de reserva de padrões durante o desenvolvimento das sementes. O objetivo deste trabalho é descrever o desenvolvimento morfoanatômico das sementes, bem como identificar os principais compostos orgânicos armazenados nas sementes. Para atingir esse objetivo, foram realizadas análises histológicas e histoquímicas das sementes em desenvolvimento. Os resultados revelaram que a semente é albuminosa, bitegmica e que tegumento interno da semente dá origem as ruminações do endosperma. Além disso, os resultados indicam que as reservas nutritivas das sementes de açaí são encontradas nas paredes celulares espessadas pelo endosperma na forma de polissacarídeos de reserva. Nossas descobertas fornecem informações úteis para futuros estudos sobre biología reprodutiva, propagação e melhoria de uma cultura tao lucrativa.

Abstract Although the consumption of açaí (Euterpe oleracea) pulp has long been an important component of the diet of the peoples from the Amazon, the açaí palm tree has recently attracted economic and scientific interest because of its vast array of bioactive compounds found in the fruit pericarp. The açaí seeds are the largest byproduct after pulp extraction and have potential for use in ethanol production, but this process is hindered by limited knowledge of seed biology, chemical composition and pattern reserve deposition during seed development. The aim of this work was to describe the morphoanatomical development of the seeds, as well as to identify the main organic compounds stored in the seeds. To achieve this goal, histological and histochemical analyses were performed on developing seeds. Results showed the seed is albuminous, bitegmic and that ingrowths of the seed coat give rise to a ruminate endosperm. Moreover, the nutritive reserves of açaí seeds are found in the endosperm thickened cell walls as reserve polysaccharides. Our findings provide information for future studies dealing with reproductive biology, propagation and the improvement of this profitable crop.

Abstract Education is an important factor in the formation of behaviors and social postures that an individual adopts every day and in their participation in important events. There is a severe education problem in Mexico, according to data from INEGI (2015) 93% of the 15-year-old population is illiterate. which leads to think that the educational level of the population influences attitudes and postures regarding the preventive guidelines of the pandemic. Aim. Describe how the education of society influences to be able to correctly carry out sanitary measures and prevent the Covod-19 disease from spreading and not affecting more than it has already affected the whole world. Material and methods. A cross-sectional, descriptive, observational study was conducted by applying a google survey in the states of Hidalgo, Chiapas and Estado de México to a total of 128 people. Results. A total of 128 individuals participated in this research: 63 women and 61 men. Of the total number of individuals, 46% reported having completed some degree, while 54% did not report having done so. 100% of the participants reported belief in the pandemic and 99.2% consider that there is COVID 19 in Mexico. Conclusion. In Mexico, it has been shown that education does influence health guidelines, so it is important to invest in education, this allows greater knowledge to avoid contagions and at the same time prevent future diseases or new outbreaks. Otherwise, we will continue with negative results.

Resumen La educación es un factor importante en la formación de conductas y posturas sociales que adopta un individuo día a día y en su participación en eventos de consideración. Existe un severo problema de educación en México, según datos de INEGI (2015) el 93% de la población de 15 años es analfabeta. lo que lleva a pensar que el nivel educativo de la población influye en las actitudes y posturas frente a los lineamientos preventivos de la pandemia. Objetivo. Describir cómo influye la educación de la sociedad para poder llevar acabo correctamente las medidas sanitarias y evitar que la enfermedad Covid-19 se propague y no afecte más de lo que ya ha afectado a todo el mundo. Material y métodos. Se realizó un estudio observacional descriptivo de carácter transversal mediante la aplicación de una encuesta en google en los estados de Hidalgo, Chiapas y Estado de México, a un total de 128 personas. Resultados. Se contó con la participación de 128 individuos en la presente investigación, 63 mujeres y 61 hombres. Del total de personas, el 46% refiere haber cursado algún grado de licenciatura, mientras que el 54% no refirió haberlo hecho. El 100% de los participantes refirieron creer en la pandemia y el 99,2% considera que existe COVID 19 en México. Conclusión. En México se ha demostrado que la educación si influye respecto a los lineamientos de sanidad, por eso es importante invertir en educación, esto permite mayor conocimiento para evitar contagios y al mismo tiempo prevenir para enfermedades futuras o nuevos rebrotes. De no hacerlo así, continuaremos con resultados negativos.
