Mesenchymal stem cells for diabetes mellitus treatment: new advances
Authors: Dang Loan Thi-Tung , Phan Ngoc Kim , Truong Kiet Dinh
Published: January 2017

Mesenchymal stem cells (MSCs) are the most widely used stem cells of the human body due to ease of successful isolation and expansion for many years. In particular, from 2012 until now, MSCs have been widely clinically used to treat various diseases, including graft versus host disease (GVHD), Crohn’s disease, and knee osteoarthritis. In this review, the applications of MSCs in diabetes will be reviewed and discussed. Diabetes mellitus type 1, also known as Type 1 diabetes (T1DM), is an autoimmune disease in which immune cells attack the beta cells in islets of Langerhans (pancreatic islets). Although type 2 diabetes (T2DM) is considered to be a disease related to insulin resistance, several recent studies have shown some relation of immune dysfunction in this disease. Therefore, MSC transplantation may be a beneficial treatment for both T1DM and T2DM. MSC transplantation in preclinical trials and clinical trials for T1DM and T2DM have shown a moderate to significant improvement in diabetes without adverse side effects. In this review, we will discuss some of the updates from preclinical and clinical trials of MSC transplantation for diabetes.

Prevalencia y conocimientos de estudiantes de enfermería de una universidad pública sobre el cuidado a la persona que consume drogas lícitas
Authors: Medina-Fernández Josue Arturo , Ortiz-Gómez Laura Dioné
Published: January 2017

Introducción. El abuso de drogas lícitas se constituye en uno de los principales problemas de salud pública a nivel internacional y nacional. En México, la Encuesta Nacional de Adicciones 2011 reporta que el 53,9% de adultos consume alcohol y el 19,9%, tabaco; en Yucatán, la proporción de adultos que consumía alcohol fue de 52,6% y tabaco, de 17,7%. El objetivo del estudio fue determinar la prevalencia y el nivel de conocimientos de estudiantes de enfermería de una universidad pública sobre el cuidado a la persona que consume drogas lícitas. Método. Utilizando una metodología cuantitativa, de corte transversal; con muestreo aleatorio estratificado por semestre, y selección por muestreo aleatorio simple. Se aplicó el cuestionario CDCCP, para obtener datos sociodemográficos, así como la prevalencia en alcohol y tabaco. Se aplicó el instrumento NEADA α=0.70 para medir el nivel de conocimientos respecto del cuidado a la persona que consume drogas lícitas. Se encuestó a 74 estudiantes, 56.8% mujeres y un 43.2% hombres; x=21.14, =2.462 años. Resultados. La prevalencia del consumo de los estudiantes fue de 81,1% de alcohol y 51,1%, de tabaco. De acuerdo con el NEADA, se obtuvo un x=20,15 puntos y =2,280 puntos, que corresponde a un nivel medio de conocimientos. Conclusión. Los estudiantes de pregrado presentaron una prevalencia global elevada del consumo y un nivel de conocimientos medio sobre el cuidado al paciente que consume drogas licitas, lo que sugiere, el desarrollo de programas de salud dirigidos a los estudiantes a fin de reducir o evitar el aumento de la prevalencia del consumo. Por otro lado, se observa la necesidad de reforzar los conocimientos del estudiante de pregrado para la atención a pacientes consumidores, las condiciones crónicas, psicológicas y sociales inherentes.

Abstract:

Introduction: Understanding adolescent smoking trajectories is necessary for tailored prevention programs. Aim: To identify adolescent cigarette use patterns and risk factors of smoking trajectories by a longitudinal study. Method: We conducted a three-year prospective survey in two age cohorts (6th and 9th school grades) of metropolitan adolescents (n = 1,092) with yearly data collection by self-administered questionnaires. Five smoking trajectory groups were defined by cigarette smoking data. Results: 67.5% of the sample remained nonsmoker, 11.3% smoked all the time, 14.3% were initiators, 3.3% quitters and 3.7% experimenters. Members of smoking trajectory groups differed significantly from each other according to number of smoking friends, parental smoking, family structure, academic achievement and weekly allowance at baseline. Conclusions: Concerning tobacco prevention programs, adolescents are not homogenous population, because distinct set of risk factors are highlighted in their different smoking behavior groups. Orv.

Abstract:

Spontaneous bacterial peritonitis occurs most commonly in cirrhotic patients with ascites. Pathogens get into the circulation by intestinal translocation and colonize in peritoneal fluid. Diagnosis of spontaneous bacterial peritonitis is based on elevated polymorphonuclear leukocyte count in the ascites (>0,25 G/L). Ascites culture is often negative but aids to get information about antibiotic sensitivity in positive cases. Treatment in stable patient can be intravenous then orally administrated ciprofloxacin or amoxicillin/clavulanic acid, while in severe cases intravenous III. generation cephalosporin. Nosocomial spontaneous bacterial peritonitis often caused by Gram-positive bacteria and multi-resistant pathogens can also be expected thus carbapenem should be the choice of the empiric treatment. Antibiotic prophylaxis should be considered. Norfloxacin is used most commonly, but changes are expected due to increase in quinolone resistance. As a primary prophylaxis, a short-term antibiotic treatment is recommended after gastrointestinal bleeding for 5 days, while long-term prophylaxis is for patients with low ascites protein, and advanced disease (400 mg/day). Secondary prophylaxis is recommended for all patients recovered from spontaneous bacterial peritonitis. Due to increasing antibiotic use of antibiotics prophylaxis is debated to some degree. Orv.

Materials and methods: In the study 62 ballet dancer women (average age: 14.89 ± 1.21 years) were included. Intervention group: n = 30 participant, average age: 14.86 ± 1.00 years, control group: n = 32 participant, average age: 14.91 ± 1.37 years. We examined the pain intensity that occurs during training with visual analog scale, the habitual posture with photogrammetry, the abdominal muscle strength with Kraus–Weber test, the static muscle strength of the trunk muscles with core test and the lumbar motor control with leg lowering test. The intervention group did a trunk prevented exercise program during 3 months, and then we examined them again. Results: In the intervention group the intensity of pain significantly decreased (VAS1: p = 0.012; VAS2: p = 0.021), the abdominal muscle strength significantly improved (K–W. B: p=0.025; K–W. C: p<0.001), the static muscle strength of trunk muscles significantly increased (Core-test: p<0.001) and the lumbar motor control significantly improved in both legs (Leg low. R.: p<0.001; Leg low. L.: p<0.001). Also, the habitual posture greatly improved (frontal view: 34.78%, side view: 52.17%). Conclusion: In ballet dancers with a special exercise program, which improves the conditions of trunk muscles, the motor control of lumbar regions can be improved and the lower back pain and the incidence of injuries can be reduced.

Насадочная часть тепло-массообменных аппаратов пленочного типа выполнена на основе многоканальных композиций из полимерных материалов с каналами сложной конфигурации. Предложена математическая модель, описывающая процессы совместного тепло-массообмена в испарительных охладителях непрямого типа НИОг и выполнен, на основании полученных авторами экспериментальных данных по эффективности процессов тепло-массообмена, сравнительный анализ возможностей разработанных охладителей. В эксперименте варьировали начальные параметры (температуру и влагосодержание) воздушного потока и соотношения контактирующих потоков газа и жидкости. Экспериментально установлены предельные нагрузки по газу и жидкости и рассмотрен вопрос об опасности «захлебывания» «мокрых» каналов насадки. Получены данные по задержке жидкости в насадочном слое, определяющей реальную поверхность контактирования потоков газа и жидкости. Показана опасность реконденсации во вспомогательном воздушном потоке в НИОг и НИО-Rг с ростом глубины охлаждения, когда вспомогательный воздушный поток в пределах насадочной части может оказаться полностью насыщенным влагой.

The goal of this work is to assess and to compare the autonomic nervous system (SNA) response in Parkinson’s disease (EP) patients and healthy subjects in order to evaluate the possible dysautonomia presence. Electrocardiogram and photoplethysmography signals were acquired during the following maneuvers: rest, orthostatic change (Post-CP), controlled breathing (RC) and hyperventilation (Hip.). The signal processing was carried out by means of linear and no linear indices of heart rate variability (VFC), indices of pulse transit time (PTT) and baroreflex sensitivity (– index). Parkinson disease patients showed an attenuated sympathetic modulation mainly during Post-CP and the cardiovagal response resulted blunted during RC. Approximate entropy was significantly decreased in healthy subjects with respect to EP subjects during RC. In addition, the index – resulted in lower values in EP patients with respect to healthy subjects during the complete protocol, this result suggests that the baroreflex control in EP patients is blunted. However, is necessary to increase the number of subjects with the objective of determining levels of dysautonomia. The protocol designed to evaluate the dysautonomia presence in mexicans with EP through non invasive signals provides information about the SNA behavior.

Morphological changes in brain tumors may be related to their malignancy. The objective of this work is to be able to detect and quantify these changes in a magnetic resonance imaging, since it can represent an important advantage for the noninvasive diagnosis in patients. One way to identify such morphological changes can be through the measurement of their tortuosity. The discrete tortuosity is a descriptor that characterizes bi-dimensional curves, as the contour of a region. In this work an alternative procedure for calculating the volumetric tortuosity of a surface is proposed. This technique is based in the slope chain code of the surface contour of a volume, and here we call it tridimensional discrete tortuosity. This descriptor is used as a morphometric index to study the tortuosity of brain tumors. For this, magnetic resonance images from 20 patients with low and high malignancy levels were analyzed, considering four regions: edema, whole tumor, enhancing region, and necrotic region. As a result, the tortuosities of the different regions are presented, with significant differences only in some of them. It should be noted that a disadvantage that is present, is the dependence of the measurement to the use of a robust method of segmentation, nevertheless the proposal of the discrete tortuosity for volumetric surfaces is satisfactory.

The skin in the human is the largest organ, his integrity represents protection against various chemical, biological and mechanical agents. The injuries in this tissue are solved by forming a scar, however, different molecular alterations may overstimulate this process, leading to the formation of aberrant scars (hypertrophic or keloid). The most recommended treatment for such injuries is the intralesional application of triamcinolone acetonide (TA) and on the other hand, dehydroepiandrosterone (DHEA) is a pro-hormone that has a wide variety of biological effects such as regulation of the synthesis of collagen fibers, cell protection, anti-tumor properties, anti-inflammatory and anti-oxidant. In this paper, the combination of AT-DHEA on proliferation and cell death in fibroblast cell line 3T3-L1 was studied. The results showed that the AT 100 and 1000 M DHEA to inhibit proliferation by 50 and 40% respectively. The combination of AT-DHEA (10000-10 M) inhibits cell proliferation and induce programmed cell death, so this combination could be used in hypertrophic or keloid scars for disposal.

The aim of the present study is to determine the influence of the position of the collecting channels on intraocular pressure and its contribution to the development of glaucoma. Numerical simulations were performed using the finite element method for two case studies. The first case is a simplified model of rectangular section that simulates the flow between two collecting channels. The second model describes flow throughout the Schlemm channel (CS), considering that it is a rigid ring of constant thickness, with four distributions of the collector channels. The pressure and velocity profiles are shown for both cases. In the simplified case, there are differences of 10 P a between the average pressures. The second model shows that the symmetric arrangement has a constant pressure distribution while the asymmetric cases have variations of 2 P a. The results confirm that the position of the collecting channels influences the intraocular pressure. This study shows that a transient analysis is needed to understand the whole process, considering the elastic properties of the CS as well as the variations of diameter of the collecting channels.

The motor disability is a problem at the global level and according to the census 2010 from INEGI, in Mexico, people with mobility problems represent 58.3 % of the population with disabilities. To face this problem, robotic devices for rehabilitation have emerged which allow to perform therapies with accuracy, efficiency, reduction of physical efforts and the opportunity to perform them in group. However, these devices may not match the mobility of the members to rehabilitate and their adaptation to the mexican anthropometry is limited. In this article, the design of an exoskeleton focused on the Mexican adult population with partial loss of mobility in the shoulder is presented. The objective is to develop an exoskeleton capable of generating the 3 basic movements of the shoulder (flexion-extension, abduction-adduction and internal-external rotation) considering the anthropometric measurements of the target population. For the design of the prototype, an adaptation of the mechatronic design methodology for robots is used. The proposed design is validated kinematically through numerical simulations in Matlab® and ADAMS™, the numerical results prove the range of mobility of each exoskeleton joint. Moreover, a finite element analysis is carried out to quantify the stress and strain levels in the exoskeleton, verifying the selection of materials for its manufacture.

Cerebral Palsy (CP) is a group of permanent pre, post and perinatal disorders of the motor and posture development due to non-progressive alterations in brain’s natural development caused by injuries in the Central Nervous System. Due to the importance of the daily use of the upper limb members, it’s important to consider more efficient ways to evaluate the performance in patients diagnosed with CP. One way to obtain an evaluation of the performance of the thoracic member is recording defined movements and calculating the smoothness, using an instrumented sorting block box. Our objective is to create a protocol of valuation for the upper member that is objective, efficient and that gives a quantitative feedback of the grade of the motor affectation of child with PC in a clinical environment.

This paper presents an application of the Chan-Vese algorithm for a semi-automatic segmentation of anatomical structures of interest (lungs and lung tumor) in thorax 4DCT images, as well as its threedimensional reconstruction. Segmentations and reconstructions were performed in 10 CT images, which conform an inspiration-expiration cycle. The maximum displacement of the lung tumor was calculated using the reconstructions of the beginning of inspiration, beginning of expiration, and the voxel size information. The proposed method was able to succesfully segment the studied structures regardless of their size and shape. The threedimensional reconstruction allow us to visualize the dynamics of the structures of interest throughout the respiratory cycle. In the near future, we are expecting to be able to have more evidence of the good performance of the proposed segmentation approach, and to have feedback from a clinical expert, giving the fact that the knowledge of anatomical structures characteristics, such as their size and spatial location, may help in the planning of radiotherapy treatments (RT), optimizing the radiation dose to cancer cells and minimizing it in healthy organs. Therefore, the information found in this work maybe of interest for the planning of RT treatments.

This study was undertaken to identify the effect of ᴅ-allulose and sucrose solution on mass transport phenomena and diffusion coefficient of sugar solution. Potato samples were immersed in sugar osmotic solution (20% w/v) at room temperature (20°C). The mass transfer kinetics was measured at 30 min, 1 h, 2 h, 4 h, 6 h, 8 h and 16 h. The optimum value of ᴅ-allulose content in sample after immersion with ᴅ-allulose solution was higher compared with sucrose content in sample after immersion with sucrose solution. Also, ᴅ-allulose has higher diffusion coefficient compared with sucrose. Diffusion coefficient of ᴅ-allulose and sucrose were 6.43 x 10-10m2s-1 and 2.83 x 10-10m2s-1, respectively. ᴅ-Allulose has potential effect to accelerate an ingredient movement into the food materials. The acceleration movement of ingredients such as ᴅ-allulose into the food materials may be useful in food processing and preservation such as curing process of meat and fish.

Published: January 2017

A 51-year-old male underwent replacement of the ascending aorta for acute type A dissection. The post-operative course was uncomplicated, and he was discharged home. Approximately a month later, control CT revealed an enlarging pseudoaneurysm of the proximal anastomosis. The patient was re-operated, and a Bentall operation with mechanical prosthesis was performed. Again, surgery was uncomplicated, but follow-up CT scan revealed a recurrent small pseudoaneurysm of the proximal suture line. He was managed with close observation, and control CT at four months showed complete resolution. Conservative treatment of small postsurgical pseudoaneurysms is discussed.   
Improving myocardial protection. The key variables, which effect troponin release after CABG.
Authors: Sladden David , Schembri Kevin , Camilleri Liberato , Xuereb Robert , Galea Joseph
Published: January 2017

Background

Myocardial cell ischaemic injury during cardiopulmonary bypass and aortic crossclamp remains a key limiting factor to patient outcomes in coronary artery bypass grafting. Troponin I has been shown to be an effective indicator of myocardial ischaemic injury and achieves peak levels early post-operatively.

Methods

All consenting CABG patients from one centre, during a one year period, were recruited. All surgeries were performed using identical techniques besides the cardioplegia volume and number of doses. Troponin I levels were checked regularly post-operatively until a peak troponin I level was ascertained. All the patient demographics, crossclamp times, bypass times and cardioplegia dosing were analysed using multiple combinations of statistical tools.

Results

172 patients were included in the study and cardiopulmonary bypass (CPB) time was found to be significant as a single variable (p=0.033). The combination of CBP time and ischaemia time (p=0.002) and the combination of CPB time and multidose cardioplegia (p=0.009), were both found to significantly effect peak troponin I levels. Another analysis was performed on the volume of cardioplegia used. While this was not significant as an individual variable it did become significant when combined with ischaemia time at a threshold total cardioplegia volume of 750mls (p=0.026).

Conclusions

The conclusion therefore is that using over 750mls of cardioplegia in multiple doses will safely protect against an ischaemia time of up to 62min. However there is no protection against the CPB time, which proved to have the most impact on myocardial cell damage in our practice.

Highlights 
We describe a novel technique to exchange an Impella over a guide-wire, preserving the arteriotomy access and to lower the risks of vascular complications. We describe this technique in the context of two interesting cases. The first case is of a young man with myocarditis and cardiogenic shock from a previously undiagnosed systemic lupus erythematous. The second case is of a woman with ST elevation myocardial infarction and cardiogenic shock requiring complex percutaneous intervention. The implantation of Impella CP served as circulatory support in these cases as myocardium recovered but was complicated by access site bleeding. We were able to remove the Impella device while maintaining the access sheath to allow for adequate hemostasis prior to sheath removal.  We believe the readers of the journal will find these images and technique interesting and useful in their own practice. 
Brugada Syndrome: Current Practices in Diagnosis, Prognosis, and Treatment
Authors: Ali Muhammad
Published: January 2017

Brugada syndrome (BrS) is a hereditable syndrome, first reported in 1992, characterized by right bundle branch block and an uncommon form of ST-T wave elevation in the V1 and V2 leads and associated with risk of sudden cardiac death (SCD) arising from polymorphic ventricular tachyarrhythmias. BrS is an autosomal dominant inherited condition; however, more than 50% of BrS cases may be sporadic. Approximately 20% to 25% of BrS cases originate from loss of function mutations in the SCN5A cardiac sodium channel.

The diagnosis of BrS is mainly based on electrocardiogram. SCD due to ventricular fibrillation can be the first clinical presentation of BrS. The insertion of an implantable cardioverter-defibrillator remains the only approved effective measure to prevent SCD in BrS patients. Risk stratification in BrS is still challenging. Because the role of electrophysiological study (EPS) for estimating prognosis in BrS patients has been controversial, but the expert consensus published in 2013 (Priori et al, 2013) considered the performance of EPS, class IIb. Future randomized studies focused on risk stratification and the value of radiofrequency ablation in BrS patients are needed.

This review provides a succinct general overview of BrS focusing on current practices in diagnosis, prognosis, and treatment.

Published: January 2017

Objective: To examine the relationships be­tween spirituality and physical activity and sedentary behavior in a sample of Latino adults in Massachusetts.

Design: This is a cross-sectional analysis of the Lawrence Health and Well Being Study; a study that was conducted among patients at the Greater Lawrence Family Health Cen­ter (GLFHC) in Lawrence, Massachusetts.

Participants: 602 Latino or Hispanic adults aged 21 to 85 years completed the study.

Results: There was a significant nega­tive relationship between spirituality and sedentary behavior (β= -.12, p = .004). Although not statistically significant, higher spirituality was associated with increased odds of engaging in physical activity. There were no significant associations between spirituality and physical activity among men or women. Men with greater spirituality were significantly less sedentary (β = -.17, P = .005). There was no relationship between sedentary behavior and spirituality among women.

Conclusions: This study found that indi­viduals who are more spiritual are also less sedentary, and this association was stronger in men than women. Findings provide insight for developing future interventions to promote activity in this high-risk popula­tion, which has been greatly understudied. Future research endeavors should consider investigating the impact of spirituality-based messages to reduce sedentary behavior among Latinos.

Authors: López Alexis , Osorio Sánchez Karime
Published: January 2017

The main goal of this study is to examine the perceptions of students from a master’s program about how they receive feedback and the quality of such feedback. Results show that students receive it in different ways, and most of them have a positive most of them have a positive perception of its role in the learning process. Overall, students believe that feedback is formative when teachers allow them to use it and when it is constructive, timely, clear and relevant. The most important thing in the feedback process is that students can use the information they receive to improve the learning process.

This is a quantitative investigation with a correlational scope that aims to establish the existing relationship between the preferred style for teaching resources and strategies and the initial professional training of teachers from the District’s Department of Education in Bogota. Fonseca’s teaching styles test was applied in order to determine them. The sample consisted of 118 students from the Master of Science Teaching from Universidad Autónoma de Colombia. Results show that science teachers’ preferred style for teaching resources is the conference style, while teachers of the initial training in basic sciences program prefer the workshop style. The least preferred style is the prose style.
Influencia de las TIC en la escritura juvenil contemporánea
Authors: Garzón Bohórquez Aída Patricia
Published: January 2017

Writing mediated by new technologies is a vernacular practice accepted by young people because the net offers them authentic environments to improve ties, develops collaborative work and provides resources that enable the creation of meaningful knowledge. Therefore, virtual writing becomes a support to independent learning that facilitates the production of texts, since these formats make new ways of writing viable. This investigation stresses the importance of chat speak as a new discursive “genre” to introduce reflection on ICT and curriculum at schools, as the new paradigm is virtual and schools should teach young men and women to be proficient in the use of digital tools to manage and create knowledge.
Características morfológicas de sorgo sacarino BRS 501 em deficit hídrico
Authors: Moreira Luciano Rezende , Carvalho Ervilha Jardélcio Damião , Vidigal Juliana Gonçalves , Miranda Glauco Vieira
Published: January 2017

A cultura do sorgo [Sorghum bicolor (L.) Moench] destaca-se das demais por tolerar tanto o deficit hídrico como o excesso de umidade no solo, em situações ambientais muito secas e/ou muito quentes, nas quais a produtividade de outros cereais torna-se antieconômica. Este trabalho objetivou avaliar os efeitos da irrigação na conformação radicular na fase inicial de desenvolvimento do sorgo sacarino. Nesse propósito, foi utilizada a cultivar BRS 501 submetida a quatro níveis de irrigação que se basearam em 80%, 60%, 40% e 20% da capacidade de campo (CC). A diminuição na disponibilidade de água no solo influenciou negativamente a maioria das características avaliadas com exceção da relação entre o sistema radicular e a parte aérea (SR/PA), diâmetro médio de raiz (DMR) e área radicular específica (ARE). Conclui-se que o crescimento das plantas de sorgo sacarino é sensível à diminuição de água no solo, sendo afetado pela baixa disponibilidade hídrica. A metodologia utilizada, comum a outras culturas, adequa-se ao sorgo sacarino para estabelecer disponibilidades hídricas em estudos com a finalidade de discriminar cultivares tolerantes à seca.

Published: January 2017

As falhas em rolamentos são muito comuns em vários segmentos industriais. O monitoramento do estado de funcionamento através de técnicas preditivas é imprescindível para evitar que as falhas inesperadas ocorram. Dessa forma é possível aumentar a disponibilidade do equipamento dentro da planta industrial. Um dos parâmetros de monitoramento mais relevantes para avaliar a condição de trabalho de um equipamento é analisar o seu modo de vibração. Entretanto, os sinais de vibração provenientes de defeitos em rolamentos são de natureza transiente, não sendo bem averiguados pelas técnicas de análises convencionais. O objetivo deste trabalho consiste em apresentar um estudo da Transformada de Wavelet, técnica recente e promissora para detecção de falhas em rolamentos, demonstrando as suas vantagens e limitações utilizando o software Matlab. Os defeitos foram inseridos em diferentes rolamentos, montados numa banca de teste. Os resultados revelam a potencialidade e viabilidade da Transformada de Wavelet, podendo ser incluída em programas de Manutenção Preditiva.

Que currículo escolar favorece uma educação inclusiva?
Authors: Santiago Sandra Alves da Silva
Published: January 2017

O presente artigo discute os significados do currículo escolar frente à proposta inclusiva. A partir de um estudo bibliográfico analisou as diferentes perspectivas de currículo, e fundamentado na análise documental, estudou os diferentes dispositivos legais que sustentam a perspectiva inclusiva. Com base nestas análises, os resultados apontam para a tendência de currículo Pós-Crítica como a que melhor atende as necessidades de construção de uma escola verdadeiramente inclusiva. E considera que a tendência pós-crítica do currículo rompe com o jeito de ser e fazer a escola e questiona as verdades absolutas de que os alunos com deficiência necessitam de uma escola diferente ou segregadora.

Revista Vértices: uma análise da produção científica
Authors: Rosa Mendes Luiz Fernando , Almeida de Souza Silva Grazielle , Ribeiro Machado Letícia
Published: January 2017

Este estudo realiza uma análise da produção de artigos científicos originais entre os anos de 1997 a 2012 pela revista Vértices da Essentia Editora, do Instituto Federal Fluminense, com intuito de auxiliar na gestão da mesma. O trabalho teve como referência os estudos de Francisco (2011) sobre a RAE-Eletrônica, e a partir deste, foi proposta uma pesquisa exploratória de caráter quantitativo e qualitativo dos 250 artigos científicos distribuídos nos 14 volumes, e do nível de acesso ao website da revista. A pesquisa mostra que o Periódico vem aumentando a sua visibilidade nacional. Também se verificou que 41% dos artigos da Revista pertencem à área de Ciências Humanas e dois terços dos autores não pertencem à mesma Instituição da Vértices. Isso denota que a endogenia tem um valor aceitável e, desta forma, o Periódico apresenta pluralidade de autores e Instituições. Além disso, em especial nos últimos três anos pesquisados (2010, 2011 e 2012), a Vértices aumentou o número de publicações que tratavam de questões de cunho socioambiental, socioeconômico e político referentes às regiões Norte, Noroeste, Baixada Litorânea e Lagos do estado do Rio de Janeiro.
