Some observational studies have shown that only a small number of diabetic patients achieve optimum control of glycaemia and cardiovascular risk factors. The aim of this study was to analyze whether patients with type 2 diabetes mellitus treated in primary care achieve adequate control of glycemic levels and cardiovascular risk factors. This was a retrospective, record-based, cross-sectional study that included eligible patients from 35 to 90 years old with type 2 diabetes mellitus treated in Primary Health Care Center in Podgorica. We investigated electronic records of 531 diabetic patients. The observed prevalence of type 2 diabetes mellitus among individuals between ages 35 and 90 years, was 11,84 %. Half of the patients were female. The mean age was 65,88±9,86 years. The mean value of HbA1c was 7,56±1,71. Fifty-nine percents of patients achieved optimal levels of HbA1c ≤ 7 %. Also, more than half of patients achieved target levels of blood pressure while 27.9% achieved LDL ≤ 2.6 mmol/L. Fifty percent of patients were non-smokers and 45.1 % were obese. Among patients on primary prevention only 5.7 % had met all target levels while on secondary prevention that number was even smaller 3.7 %. Our study showed that control of HbA1c and blood pressure was similar to other studies but reaching target levels of LDL was challenging for our patients. Further analysis are needed in order to discover the reasons for poor control of certain CVRF and to develop strategies for its optimal management.

Published: May 2019

Crouzon syndrome is one of the most common syndromic craniosynostosis. We present complex course of treatment in a child with Crouzon syndrome presented with multisuture craniosynostosis and hydrocephalus. A 3-months-old boy was admitted with clinical signs of hydrocephalus and turribrachycephaly. Firstly, the hydrocephalus was addressed. The ventriculoperitoneal shunt with programmable valve was implanted. Secondly, in May 2017, posterior calvarial remodeling was done. Finally, after the child recovered, anterior calvarial remodeling with fronto-orbital advancement was performed.  This completed the calvarial remodeling in this patient. Child is doing well, so far completing milestones of child development in time. This case presents an extremely complex case of syndromic multisuture craniosynostosis, in which it was necessary to perform the entire calvarial remodeling to correct the deformity and to provide a chance to the brain to grow and develop without constrictions.

Bleeding during liver resection is a significant threat to the clinical outcome. Portal triad occlusion with complete ischemia of the liver flow of hepatoduodenal ligament is a well-documented, safe and useful way to reduce this problem. Although the technique is efficient in limiting blood loss, there is still controversy concerning potential disadvantages and subsequent reperfusion liver injury. A prospective analysis will include at least 30 patients 18-75 years old, who are undergoing liver resection due to metastases of the colorectal carcinoma. After signing the informed consent, the parameters will be analyzed in three phases, pre-, intra- and postoperatively. During surgery (indicated by a surgical/oncological team of doctors not related to our study) liver tissue samples will be taken of the “healthy liver” (not involved in the tumor process) in which after tissue homogenization, analysis of parameters will be done responsible for the development of liver injury. This research will not affect the clinical practice, course and outcome of the treatment in patients who are included. The study may be useful for future patients who will undergo liver resections. The application of modern research methods with scientific validity of statistical processing of data and the use of appropriate literature, significant data will be obtained about the character, i.e. intensity of damage of the liver tissue in patients undergoing liver resections.

Percepción de seguridad, uso y mantenimiento de los parques municipales en Costa Rica, según el sexo de los usuarios
Authors: Espinoza Duran Juliana , Mendez Estrada Victor Hugo , Monge-Nájera Julián
Published: May 2019

Los parques y otras zonas verdes mejoran la salud física y mental de los habitantes de las ciudades, pero en Costa Rica se sabe muy poco sobre la percepción que tienen de ellos sus usuarios. Aquí analiza­mos la influencia del sexo en la percepción de la seguridad, el uso y el mantenimiento en una muestra grande y representativa de Costa Rica (27 parques municipales escogidos aleatoriamente). Aplicamos oral­mente y en persona una encuesta validada a 30 visitantes por parque. Hallamos que independientemente de la iluminación y la vegetación, las mujeres se sienten inseguras a toda hora; creen que hay muchos delitos; aunque en muy pocos casos han sido víctimas, y que califican más bajo el mantenimiento y la vigilancia que los hombres. La compa­ración con otros estudios indica que nuestros resultados son similares a los obtenidos en el resto de América Latina y más allá.
The power of short lectures to improve support for biodiversity conservation of unpopular organisms: an experiment with worms
Authors: Monge-Nájera Julian
Published: May 2019

Public opinion is important in obtaining support for the conservation of biodiversity, and invertebrates have a "public relations problem" because -for reasons that are both cultural and biological- they are poorly known and often unpopular. In this article I present the results of an experiment on the power of a short lecture to improve attitude towards invertebrates, using the case of velvet worms. Velvet worms are "living fossils" that have inspired a wide range of cultural expressions, probably because of the adhesive net they use to capture prey. For the experiment, a group of 141 Costa Ricans, aged 10 to 58 years old, rated their reaction to a color photograph of Epiperipatus biolleyi, a Costa Rican species of velvet worm, before and after a five-minute lecture about the natural history of the worm. Even before the treatment, most of the respondents had a correct idea of the animal's anatomy (84%); supported the use of public funds to conserve it (71%); and more than half perceived the worm in a positive way (58%). They stated that they were willing to donate a mean of US$7,00 from their own pocket for the worm's protection (six times more if they had university education); and were less likely to reject the worm if they kept pets at home. Gender, age and education did not have any effect on most variables of attitude and knowledge. Compared with the control group, the group that received the lecture had a 17% improvement in attitude. The Costa Rican educational system, focused on nature and its conservation, can explain the generally good attitude and knowledge of invertebrates found in this study; and a five-minute natural history lecture can produce a significant improvement in perception of an animal that is generally unattractive: a worm.
Extension of life expectancy and contribution to the increase of death of genetic origin
Authors: Bellis Gil , Parant Alain
Published: May 2019

The purpose of this paper is to investigate the consequences of the human
ageing on the frequency of genetic diseases. Taking the exemple of the
Huntington disease, we try to evaluate the expected increase in the number
of persons affected in France, until the year 2020, based on demographic
data and population projections. Because of the frequency of the gene
responsible of this particular pathology, the number of cases is expected to
raise according to increase in health expectancy and the future growth of
aged population. Population ageing seems responsible of the appearance of
endogenous diseases which are often provoking invalidity.
Demographic trends and population prospects in Southeastern Europe
Authors: Kotzamanis Byron
Published: May 2019

Three basic questions are under consideration in today?s demographic
community: a) the European geography of demographic behaviors allows us to
consider the geopolitical area of S.E. Europe as uniform and clearly
distinguished from the rest of Europe, b) to what extent the observed recent
evolutions in the ex "socialist" S.E. European countries are registered in
the long term or/and have been affected by the seismic policies and
socio-economic changes as well as the consequent difficulties the
inhabitants of these countries meet during the transition period and finally
c) the demographic perspectives of these countries and their direct and
indirect implications. In this article we do not aspire to give answers to
all of the above questions. Initially, we confined ourselves to a synthetic
presentation of post-war demographic evolutions (giving indirectly an answer
to the question of the existence or nonexistence of a demographic profile of
the Balkans). Then we focused our attention to the expected demographic
trends and the problems they raise on the one hand, to the labor market of
these countries on their course to free market, and on the other hand, to
the migration pressures these countries might bring upon the neighboring
E.C. countries.
Population - an element of agricultural development in Serbia
Authors: Todorovic Marina , Vojkovic Gordana
Published: May 2019

The author begins by discussing the relationship between agriculture and
population at a theoretical level, proceeds with a historical review of
changes in the role and significance of an individual as agricultural
producer, and finally, analyzes population as an element (potentials -
limitations) of agricultural development in Serbia. The overall production
results, and particularly the propensity to technical and technological
innovation, as well as the ability to adapt to the changed conditions are,
as we know well, crucially dependent on the structure of the working
population. Hence, the author discusses regional differences in agricultural
population by age, sex, level of education and productivity to provide a
clear illustration of the impact of this element (indicator) on the
population as the factor of agricultural production. The results show
significant macroregional differences by this element with respect to the
average for Serbia.

Introduction. Neonatal calves are often deficient in iron. Accumulating
evidence indicates that iron status is associated with disease pathologies
including diarrhea. Our objective was to examine the association between iron
status and gut function in neonatal calves with and without a history of calf
diarrhea. Materials and Methods. Calves were divided into two groups based on
their history of diarrhea; the first group were diarrheic calves (n=6) and
the second group were non-diarrheic healthy calves (n=6). Blood samples
(n=12) were collected at day 12 of age and erythrogram determination and
measurements of serum iron and total iron binding capacity were performed.
Hematological values were measured using an automatic analyzer, and
biochemical properties were determined spectrophotometrically. Fecal samples
were obtained from all calves and pH measured using semi quantitative test
strips as well as being examined by bacterial cultivation for enterotoxigenic
Escherichia coli, Salmonella spp. and Clostridium perfringens, by RT-PCR for
the presence of bovine rotavirus, bovine coronavirus and bovine viral
diarrhea virus, and by microscopy for the presence of Cryptosporidium parvum.
Results and Conclusions. There were significant iron-related changes for most
hematological indices in diarrheic calves; and iron (Fe) deficiency and
microcytic, hypochromic anemia were diagnosed. The pH of the feces was
significantly higher in diarrheic calves than in the non-diarrheic healthy
group (P<0.01). All fecal samples were negative for the analyzed enteric
pathogens. According to the results obtained, calves experiencing iron
deficiency anemia exhibit changes in gut function leading to diarrhea as
compared with a matched group of healthy calves.
Food Insecurity Screening Among Families of Children With Diabetes
Authors: Vitale Michele , Dorado Linda , Pais Vanita , Sidani Souraya , Gucciardi Enza
Published: May 2019

Little is known about screening in clinical settings for food insecurity (FI) among households of children with diabetes. This study evaluated the acceptability and feasibility of an FI screening initiative in a pediatric diabetes clinic that was implemented to help diabetes dietitian educators tailor management plans for families of children with type 1 or type 2 diabetes facing FI.

The initiative comprised three validated screening questions, a care algorithm, a community resource handout, and a poster. In total, 50 families of children and adolescents aged 0–18 years with type 1 or type 2 diabetes were screened for FI. In-person semi-structured interviews combining open-ended and Likert-scale questions were conducted with 37 of the screened families and the three diabetes dietitian educators who conducted the screening. Perceived barriers and facilitators of the screening initiative were identified using content analysis, and Likert-scale questionnaires rated interviewees’ comfort level with the screening questions. A reflective journal kept by an onsite research interviewer also facilitated the data interpretation process.

Most families felt comfortable answering the screening questions. Families with FI appreciated the opportunity to express their concerns and learn about affordable food resources. However, ∼20% of these families described stigma and fear of judgment by clinicians if they screened positive for FI. Diabetes educators also felt comfortable with the screening questions but reported lack of time to screen all families and to follow-up with resources after a positive screen. A self-reported intake form was recommended to ensure that everyone is systematically screened.

A standardized and respectful method of assessing FI could help clinicians better tailor treatment plans and support for families of children with diabetes who face FI. Based on these findings, similar FI screening initiatives should be implemented in other clinical settings as part of routine clinical practice.

Authors: Shrivastava Prashant Kumar , Singh Bhagat , Shrivastava Yogesh
Published: May 2019

Selection of an appropriate optimal range of cutting parameters during the machining of Inconel-718 is quite essential to achieve the high-quality cut and is a challenging task within this domain of study. The aim of this research is to develop a robust prediction model which can suggest the desired range of cutting parameters for accomplishing better cutting quality, precision, and geometrical accuracy. Experiments have been performed on a 300 W (CNC-PCT 300) pulsed Nd: YAG laser cutting system at various levels of input cutting parameters, viz., gas pressure, standoff distance, cutting speed, and laser power. Thereafter, the artificial neural network technique has been adopted to develop mathematical models in terms of aforementioned input cutting parameters for geometrical quality characteristics: Top Kerf Width, Bottom Kerf Width, and Kerf Taper. These developed models have been validated by comparing the predicted values with the experimental ones. Furthermore, these models have been optimized using a multiobjective genetic algorithm and particle swarm optimization techniques, in order to ascertain the optimal range of cutting parameters pertaining to better quality cut with high precision and geometrical accuracy.
FUNCTIONAL CHARACTERIZATION OF SPERMINE FAMILY TRANSPORTER caf5+ IN Schizosaccharomyces pombe (Lindner)
Authors: ÖRS GEVREKCİ Aslıhan
Published: May 2019

Polyamines are well conserved polycationic molecules that are known to interact with nucleic acids and contribute to multiple functions including cell cycle and stress response. The transport of polyamines in and out of the cell is driven by polyamine transporters that play a significant role in polyamine homeostasis. Schizosaccharomyces pombe (Lindner) caf5+ gene codes for a spermine family transporter that is yet to be characterized functionally. This study aims to understand the contribution of caf5+ on different processes previously associated with polyamines, by reverse genetics. Deletion mutants of caf5+, which are viable in normal conditions, were scanned for multiple cellular processes. The results showed that caf5+ deletion caused shorter cell length and slightly faster growth rate at the optimum conditions. caf5Δ cells also showed sensitivity to high doses of UV irradiation, while no sensitivity was observed against osmotic stress or another DNA damaging agent hydroxyurea. The mutants could successfully go through different phases of mitosis and meiosis as observed by DNA and septum staining. In summary, caf5+ gene is involved in normal growth and cell cycle progression, as well as stress response upon UV irradiation.

Este artigo apresenta análise do mercado brasileiro da aviação comercial. O interesse pela pesquisa consiste no fato de que o concentrado, ou seja, com poucos players. Por meio de estudo de caso, utilizou-se informações reportadas, demonstrações contábeis e outros dados, que possibilitaram métricas para analisar a lucratividade / rentabilidade das Cias. Observou-se que o planejamento empresarial e econômico dessas empresas e seus gestores conseguem adaptar-se rapidamente aos custos do querosene de aviação (QAV1), com variações de preços em todos os aeroportos nacionais em virtude da variação da alíquota do ICMS. O alto custo do QAV1 no Brasil é refinado e disponibilizado pela Petrobrás e distribuído por 3 empresas, sendo a principal uma subsidiaria da BR Distribuidora de Petróleo, com 61,4% do mercado e pertencente ao grupo Petrobrás. Pela convenção com empresas internacionais de aviação, o preço do QAV1 no Brasil é isento do ICMS, mas mesmo assim, é alto, em relação aos valores praticados externamente. A burocracia e os custos penalizam as operações e as incertezas econômicas, com o baixo crescimento do PIB brasileiro e a necessidade de redução do total de aeronaves em operação e dos Slot (aeroportos atendidos). mesmo com taxas de juros externas negativas. As receitas em reais e o leasing das aeronaves em dólar, expõe a riscos maiores.  As empresas não criam opções para redução do principal custo - QAV1 - mesmo com a importação liberada. A baixa da commodity petróleo não foi prevista pelas Cias. aéreas e sua redução não tem possibilitado lucros maiores no exercício. Mesmo com o aumento da quantidade de passageiros transportados, não se obtém a rentabilidade econômica – financeira esperada, resultando em destruição de riqueza na operação.

Distribution electric networks are an important link in the system of production, transmission and consumption of electric energy. The precise configuration and setting up the relay protection and emergency automation devices, including the right choice of the device working parameters, are of great importance for the reliable operation of power grids. Problems with power supply may appear either as poor quality of electricity supply (instability or distortion of voltage, its frequency fluctuation, low capacity of the power grid), or as its unreliability voltage loss. Recently, in the Astrakhan region there has been recorded an increase of electrical loads due to the growing number of enterprises and energy supply building in industry and household. The search for variants with reduced capital investments in the process of the large-scale and expensive energy construction, as well as the selection of simple and relevant proposals for the development and elaborating power supply systems are important issues for designing power lines. The analysis of the electrical network reliability factors of “Astrakhanenergo”, the branch of “IDGC of the South”, PJSC has been done.

La organización sindical de los trabajadores agrarios en Uruguay: origen, trayectoria y perspectivas
Authors: Riella Alberto , Mascheroni Paola
Published: May 2019

Los asalariados agrarios de Uruguay han presentado históricamente un rezago en sus derechos laborales y en su organización sindical. El propósito del artículo es reflexionar sobre la situación actual del sindicalismo agrario en un escenario político de expansión y reconocimiento de los derechos laborales de los asalariados y de apertura de la negociación colectiva en el sector. Con este fin se desarrollan analíticamente las distintas experiencias organizativas de los asalariados agrarios y su significación para su acción colectiva de estos trabajadores en el país. Luego se discuten los elementos de carácter más permanente que obstaculizan su sindicalización. Finalmente,  se argumenta que a pesar de las peculiaridades del contexto histórico para la aplicabilidad de sus derechos laborales, el movimiento sindical rural no ha logrado consolidarse.
Raymond Aron: la democracia y su otro
Authors: Laleff Ilieff Ricardo
Published: May 2019

El presente trabajo analiza la forma en la cual Raymond Aron pensó la polí­tica en algunos de sus textos más representativos, a saber: Introducción a la filosofí­a polí­tica [1952] y Democracia y totalitarismo [1965]. Para ello, se hace especial hincapié en la relación entre democracia liberal y sus paradigmas adversos. Se pondrá de manifiesto cómo a pesar de ciertas modulaciones, a través de la querella con determinados autores “maquiavelistas” –Michels, Mosca y Pareto–, Aron moviliza una serie de elementos que caracterizan a su decir polí­tico, mostrando aristas ligadas a sus tributos teóricos y a las causas polí­ticas sobre las que se pronunció, entre las cuales figuran su ponderación del liberalismo anglosajón y su aversión a la tradición popular francesa.
Paz y guerra: una perspectiva desde la actualidad
Authors: Bonavena Pablo , Nievas Flabián
Published: May 2019

Raymond Aron publicó en 1962 el voluminoso libro Paz y guerra entre las naciones. Realiza en él un reconocido aporte para las teorí­as de las relaciones internacionales. Transita el ví­nculo entre polí­tica y guerra, en la perspectiva de esbozar un marco conceptual para comprender las relaciones interestatales y presentar algunas proyecciones polí­ticas “racionales” para un mundo signado por las armas nucleares en el marco de Guerra Frí­a. En un itinerario polí­tico e intelectual que recorre el liberalismo y el anticomunismo, Aron ofrece un trabajo sobre el que, si bien fue concebido para un mundo bipolar, siempre es pertinente preguntarse sobre su vigencia, pues si bien ya no vemos bipolaridad, hay más paí­ses con armas nucleares en un mundo plagado de tensiones.
Clausewitz a través de la mirada de Raymond Aron. Vigencia y proyecciones
Authors: Cornut Hernán
Published: May 2019

Quienes sostienen que la teorí­a clausewitziana ha perdido su valor en el presente, probablemente se equivoquen tanto como aquellos que pretendan atribuirle un carácter dogmático e imperecedero. Mientras la tecnologí­a ha transformado la vida, la economí­a y la forma de combatir en términos instrumentales e ingenieriles, una buena parte de las nociones de Clausewitz parecen guardar validez. Por su parte, Raymond Aron es uno de los autores prominentes en el estudio de la estrategia y la polí­tica preconizadas por el noble alemán, aunque dentro del contexto de la Guerra Frí­a de mediados del siglo XX, y con un pensamiento geopolí­tico eurocéntrico. La propuesta consiste en reexaminar a Clausewitz para comprobar la vigencia de sus opiniones, y determinar en qué medida impacta en la realidad presente. Así­, este trabajo tendrá por objetivos el análisis de la condición polí­tica o filosófica de De la guerra, la consideración sobre la validez de la dialéctica entre moderación y violencia, la utilidad presente acerca de la disquisición entre teorí­a y doctrina aportada por Clausewitz, y dirimir sobre la pertinencia del concepto trinitario de la guerra en el conflicto de hoy, entre otros aspectos. Todo ello en clave de respuesta para el uso de la fuerza legí­tima en manos de los Estados a la hora de resolver sus controversias.

Good Agricultural Practices in Protected Areas: Which factors Affecting the implementation?
Authors: Karagkiozi Polyxeni , Oxouzi Eleni , Papanagiotou Evangelos
Published: May 2019

The purpose of this study is to indicate and analyse the factors that affect the decision of the Prespa bean producers to implement Good Agricultural Practices (GAP) in their farmlands. Additionally, the social characteristics of the producers are analyzed in order to obtain a broader picture. To achieve the above objectives, a logit model was applied as well as descriptive statistics for the analysis of the personal and social characteristics of farmers. The research was conducted in the Florina Prefecture of Western Macedonia through questionnaires that were filled in during personal interviews with the producers. The results of the research showed that growing PGI (Protected Geographical Indication) products, attending training seminars, the educational level of the producers, the earned income, the communication and information by an agricultural engineer affect significantly the decision of the producers to apply Good Agricultural Practices.

Published: May 2019

Particularly in the fruit juice industry, the remaining peels and pulp parts are not available for human consumption after the juices are used. It is possible to evaluate these wastes by adding them to poultry feeds. A number of studies have been conducted by researchers on the nutritional value of many fruit wastes and on the performance of poultry. Natural antioxidant content has been reported to have a positive effect on growth, microbial and immunological parameters when high fruit peels are used as feed additive in poultry feeding.
Detection of Potential Bacterial Pathogens and Aflatoxigenic Fungi from Grain Samples

Published: May 2019

Current research work was carried out for the detection of potential bacterial pathogen and aflatoxigenic fungi Aspergillus spp. from grain comprising [Rice (5), Maize (5), Wheat (5), Khessari dal (5) and Anchora dal (5)] were collected from 3 different local markets of Dinajpur District, Bangladesh. 15 bacterial isolates comprising 4 genera of bacteria were found from a total of 25 samples. The isolated bacteria were Staphylococcus spp., Escherichia coli, Klebsiella spp., Salmonella spp. with 16%, 28%, 16% and 16% prevalence respectively. Antibiogram studies revealed that overall effective drugs against isolated bacteria were Ciprofloxacin followed by Gentamycin. But resistant drugs were Penicillin, Vancomycin, Erythromycin, Kanamycin, and Amoxicillin. The variation in the sensitivity of common antibiotic could be the result of extensive and indiscriminate use of these antibiotics. Aspergillus spp. was isolated from 4-grain samples with 16% prevalence. But aflatoxigenic Aspergillus spp. was isolated from 3 samples with 12% prevalence. From the wheat samples and maize, the aflatoxigenic fungus was isolated and their prevalence in maize, wheat was 40% and 20% respectively. Their early detection can help to take preventive measures to combat economic and health losses. The study showed that earlier detections can be made by simple traditional identifications using macro and micromorphological fungal features rather than adopting the time and cost consuming molecular identification techniques.
