CAUSAS DE MORTALIDAD NEONATAL EN PARAGUAY: BIENIO 2014-2015.
OBJETIVO: Identificar las causas más frecuentes de muerte neonatal en el Paraguay en los años 2014 y 2015.
METODOLOGÍA: Estudio observacional de tipo descriptivo, prospectivo y analítico. Fueron incluidos datos de cada Región Sanitaria del Paraguay de los años 2014 y 2015 de neonatos de ambos sexos. Los datos fueron obtenidos del Subsistema de Estadísticas Vitales del MSPBS y analizados con el programa Excel© 2013 de Microsoft y Epiinfo 7. Las variables cualitativas se resumieron en frecuencias absolutas y porcentuales. Las variables fueron: Registro de nacidos vivos y muertos por regiones sanitarias y causas de mortalidad.
RESULTADOS: En el 2014, del total de nacidos vivos se registraron 1,04 % muertes en la etapa neonatal (1.172) mientras que en el 2015 disminuyó a 0,97% (1.129), con mayor prevalencia ambos años en Alto Paraguay. En cuanto a etiología prevalecen las lesiones debidas al parto, sin embargo, hubo un descenso del 8,22% de la misma, también de 1,15% en infecciones neonatales y de 1,44 % en prematuridad en el año 2015. No obstante, se registró un ascenso de 1,62% en malformaciones congénitas.
CONCLUSIÓN: Ante los resultados obtenidos, existen descensos en la frecuencia de mortalidad neonatal mediante nuevas estrategias implementadas como entrenamiento de recursos humanos, manejo de emergencias obstétricas y cursos de reanimación neonatal. Pero a pesar de los avances, el Paraguay todavía enfrenta desafíos, la relevancia radica en que la mayoría de las causas son evitables.
PALABRAS CLAVES: Mortalidad, neonato, etiología.

Published: April 2019

The continuous search in renewable energy sources for industrial and domestic utilization is very imperative and motivated this study. The study of Cow- dung and grass clippings Co-digestion are important due to the fact that successful outcome of the studies will provide a basis for waste minimization and enhance renewable energy production for global consumption. This work therefore is focused by exploiting the modified Gompertz kinetic equation in developing design models for the simulation of continuous stirred co-digester(CSC) at isothermal condition. Co-digester functional dimensions such as volume, length, space time, space velocity and heat generation per unit volume were developed for Continuous Stirred Co-digester type..The developed models were simulated using Matlab codes programming technique using design basis of 50,000 metric tons of biogas per annum at 37oC isothermal condition. The developed performance models were solved numerically using MATLAB version 7.1 within the operational limit of conversion degree, XA = 0.1 to 0.9.The results obtained showed that increase in fractional dimensions of Co-digester volume VR, length LR and Space time SV­ increases with increase in fractional conversion at constant radius. Results of space velocity (SV­) and heat generation/per unit volume (q) showed inverse characteristic behavior as increase in fractional conversion decreases space velocity and heat generation per unit volumes.. Further careful examination of the results, demonstrated that at optimal yield of 0.9 degree of conversion, Co-digester volume value of 10.0m3 at constant radius was feasible. The results as obtained in this work proved dependable relationship with fractional conversion.

Aims
To systematically review literature comparing bare metal stent (BMS) to drug-eluting stent (DES) in end-stage renal disease (ESRD) patients on dialysis. ESRD patients on dialysis often suffer from accelerated atherosclerosis and higher rate of stent-related complications including major adverse cardiovascular events. Because dialysis usually qualifies ineligibility for randomized clinical trials, an evidenced-based stent choice for these patients is scarce.

Methods
PUBMED, CINHAL, COCHRANE, EMBASE and WEB OF SCIENCE were searched for studies comparing BMS vs. DES outcome in ESRD patients on dialysis.

Results
Twenty studies including 64 232 patients were considered. The use of DES was significantly associated with a reduction in all-cause mortality [odds ratio (OR) 0.83, 95% confidence interval (CI) 0.76–0.89], death from a cardiovascular cause (OR 0.80, 95% CI 0.76–0.84) and target lesion revascularization/target vessel revascularization (OR 0.73, 95% CI 0.53–1.00). No significant difference was found in stent thrombosis (OR 1.08, 95% CI 0.50–2.33) and myocardial infarction incidence (OR 0.91, 95% CI 0.69–1.20).

Conclusions
Our meta-analysis shows a significant reduction in all-cause and cardiovascular mortality with the use of DES over BMS in dialyzed patients. Despite the lack of randomized studies, systematic use of DES in these high-risk patients should thus reasonably be considered as a first option in percutaneous coronary intervention candidates.

Aims
Ablation procedures for the treatment of atrial fibrillation lead to changes in autonomic heart control; however, there are insufficient data on the possible association of these changes with atrial fibrillation recurrence. The study aim was to assess the effects of pulmonary vein isolation (PVI) on cardiac autonomic modulation and atrial fibrillation recurrence.

Methods
We screened 52 patients with atrial fibrillation referred for PVI, of whom 20 patients met inclusion and exclusion criteria, and were enrolled in the study and followed over 6 months. Beat-to-beat blood pressure monitoring was performed 1–2 days before PVI, 1 and 6 months after PVI. We estimated pulse interval variability and spontaneous baroreflex sensitivity (BRS) both in the time and frequency domains, and performed the Valsalva manoeuvre assessing the Valsalva ratio.

Results
During 6 months after PVI, atrial fibrillation recurrence was observed in six patients. One month after PVI, pulse interval variability and BRS (sequence method) significantly decreased in all patients, returning to preintervention values by 6 months. Patients without atrial fibrillation recurrence at 1 month showed a transient reduction in pulse interval variability (frequency domain) and in BRS (both methods) in contrast to those with atrial fibrillation recurrence. A significant decrease in the Valsalva ratio observed at 1 month was maintained at 6 months after PVI in both groups.

Conclusion
Successful PVI may lead to transient autonomic alterations reflected by a reduction in pulse interval variability and BRS, with more prolonged changes in the Valsalva ratio. The efficacy of PVI in preventing atrial fibrillation recurrence seems to be related to transient parasympathetic atrial denervation.

Abstract
Colony losses, including those induced by the colony collapse disorder, are an urgent problem of contemporary apiculture which has been capturing the attention of both apiculturists and the research community. CCD is characterized by the absence of adult dead bees in the hive in which few workers and a queen remain, the ratio between the brood quantity and the number of workers is heavily disturbed in favor of the former, and more than enough food is present. Robbing behavior and pests usually attacking the weakened colony do not occur. In the present paper, the causes of the emergence of this problem are discussed, as well as the measures of its prevention.
The following factors, which lead to colony losses, are analyzed: shortage of high-quality food (pollen and honey); infestation with parasites, primarily with Varroa destructor, and mixed virus infections; bacterial infections (American and European foulbrood), fungal infections (nosemosis and ascosphaerosis) and trypanosomal infections (lotmariosis); and, finally, general management of the apiary.
Certain preventive measures are proposed: (1) providing ample high-quality forage and clean water, (2) avoiding sugarisation, i.e. superfluous use of sugar syrup, (3) meeting the nutritional needs of the colony, (4) when feeding bees, taking care of the timing and the composition of diet, avoiding pure sugar syrup which in excessive quantities may induce energetic and oxidative stress, (5) when there is a shortage of natural feed – honey in the brood chamber – use sugar syrup with natural/artificial supplements to avoid protein starvation, (6) organized control of V. destructor in the colonies is obligatory due to its vector role, and (7) compliance with hygienic and sanitary measures and principles of good apiculture practice and management in apiaries. To conclude, all preventive measures are feasible in compliance with rules and regulations concerning regular spring and autumn bee health monitoring by licensed veterinarians, who can propose adequate treatments if necessary.

Abstract
Canine parvovirus type 2 is one of the most common causes of death among puppies. Despite preventive vaccination, the disease continues to be diagnosed. The aim of the study was to provide a molecular characterization of CPV-2 isolates found in southeastern Poland. Genetic CPV-2 material was isolated from the blood (n=10) and feces (n=50) of infected dogs. The presence of CPV-2 was confirmed by amplification of sequences coding both VP1 and VP2 protein. The products of the PCR reaction with primers amplifying VP2 protein were sequenced and used for genotyping. Bioinformatics analysis of the sequenced PCR product was performed to determine the phylogenetic relationships with variants recorded in the public databases. Based on the analysis of polymorphism in the nucleotide sequence 7 nucleotide variants were detected and assigned into four amino acid groups. Representatives of three groups contained asparagine at amino acid position 426 of the VP2 protein, which is characteristic of CPV-2a. The variant from the fourth group belonged to type CPV-2b. CPV-2a is the dominant antigenic type of CPV-2 in Poland. The pathogen’s high degree of polymorphism is manifested not only by the presence of numerous variants within the type, but also by the presence of representatives of type CPV-2b. Further studies of the molecular epidemiology of CPV-2 are necessary to optimize the effectiveness of preventive measures.

Published: April 2019

Abstract
Infection of cattle with lumpy skin disease virus (LSDV) is very important from the aspect of livestock production. Although it can cause significant economic losses, available serological assays are still not sufficiently efficient and reliable. A 3-day VNT was performed using Madin-Darby bovine kidney (MDBK) cell line and LSDV isolated from clinically infected cow to improve serological diagnostics of lumpy skin disease (LSD).
In total, 325 cattle sera samples were tested in order to compare the performances of VNT and ELISA. Tested samples originated from 125 cows before the occurrence of LSD in the Republic of Serbia and 200 tested samples originated from vaccinated cows. Sera samples from vaccinated cows were collected starting from the vaccination day to 4 months after vaccination. In 7 different time intervals after vaccination sampling was carried out in 20 cows originating from one herd and in 3 different time intervals in 20 cows originating from a different herd each time of sampling.
Out of 200 samples from vaccinated cows, antibodies against LSDV were detected in 68 (34%) samples by VNT, and in 60 (30%) samples by ELISA. No positive finding was detected by VNT in samples collected before the occurrence of LSD in Serbia, while one positive finding was detected in the same samples by ELISA. The first presence of antibodies in vaccinated cattle was detected by both tests 20 days after vaccination, and the largest number of animals with antibodies against LSDV was detected 30 days after vaccination.
Comparing the results obtained by VNT and ELISA, it was calculated that kappa index was 0.913. The specificity of VNT and ELISA was 100% and 99.2%, respectively. VNT is simpler to perform compared to the recommended virus neutralization test by the OIE and can improve LSD serological diagnostics with additional sensitivity testing.

Abstract
The objective of this study was to evaluate the effect of supplementation of organic minerals on the productive performance and bone quality of broilers from 1 to 21 days of age and the intestinal health in situations of enteric challenge from 21 to 28 days of age. In a completely randomized design, with two treatments composed for minerals as sulfate and Carbo-Amino-Phospho-Chelate (CAPC), a total of 900 male broiler chicks were allocated to nine replicates and 18 experimental units with 50 birds each. 640 birds at 21 days of age were transferred to experimental cages and distributed in a completely randomized design, in factorial 2 × 2 (minerals as sulfate and CAPC × with and without enteric challenge), obtaining 4 treatments with 16 replicates and 10 birds each. In the same day of change, the group of challenged broilers received a commercial vaccine for coccidiosis that covers the Eimeria sp. At 7 days, the supplementation with CAPC minerals resulted in higher (p<0.05) weight gain and better feed conversion in relation to the inorganic source. The deposition of minerals evaluated in the tibia of broilers was not influenced (p>0.05) by the source of minerals, with the exception of Cu and Mn, whose deposition was greater (p<0.05) in the bones of poultries supplemented with inorganic source of minerals. There was higher (p<0.05) length and width of the villi and increase in the ratio villus: crypt in response to the intestinal spoliation with CAPC supplementation when compared to the inorganic source.

Abstract
During July 2018, the first clinical case of neurological West Nile virus (WNV) infection was reported in a Belgian sports mare in Belgrade, Serbia. Typical symptoms, such as hypersensitive skin reaction, disorientation, weakness, ataxia and the loss of equilibrium were reported. Detection of WNV IgM antibodies by commercial ELISA in the serum samples of the diseased mare strongly indicated acute infection. The ELISA positive results were confirmed by VNT. Hematological and biochemical parameters were in the reference range. The only finding was a minor lymphopenia. WNV RNA was not detected by RT-qPCR in the blood sample extracted seven days after the disease had broken out. The horse improved clinically in two weeks while other horses at the same premises remained asymptomatic. The clinical, serological, biochemical and molecular analyses applied confirmed the first clinical case of neuroinvasive WNV infection in horses in Serbia. The West Nile virus has been circulating in Serbia in the last decade in mosquitoes, birds, and horses, but no evidence of equine WNV clinical cases were registered so far.

Abstract
The goal of this study was to report the first case of antral stenosis in a cat. We have described a clinical case of a 9 months old domestic shorthaired cat referred for persistent and refractory vomiting, anorexia and loss of weight. Ultrasound (US) examination detected a mild gastric distension, mild wall thickening (5mm), severe serosal irregularities and a constriction between the fundus and body. Computed tomography (CT) was then performed: a severe gastric stenosis between the body and antrum with minimum contrast transit was detected and confirmed by flexible endoscopic examination. The antral localization of the stenosis was revealed after a cranial celiotomy and Y-U plastic was necessary to correct the defect. The patient completely recovered after surgery with significant body weight gain and remained in remission throughout a 2-years follow-up. While in human medicine there is evidence of acquired antral stenosis, no information is available about the same lesion in the feline species. To the best of our knowledge, this is the first case of antral stenosis in cats.
Government General Spending and Human Development: A Case Study of Nigeria
Authors: Omodero Cordelia Onyinyechi 
Published: April 2019

Abstract
The study assesses the impact of government general spending on human development in Nigeria from 2003 to 2017. The purpose is to determine the response of human development index (HDI) to recurrent and capital government expenditure. In order to achieve this objective, the multiple linear regression model linking the study variables was applied while Ordinary Lease Squares method was used to analyze the model. The results indicate that government’s capital expenditure and inflation have insignificant negative influence on HDI, corruption does not have any impact on HDI but government recurrent expenditure has strong and significant positive impact on HDI. The study concludes that resources on recurrent expenses should be reduced while more money should be invested in capital projects for human capital development in Nigeria.
Conceptual Metaphors in Political Discourse in Croatian, American and Italian Newspapers

Published: April 2019

Abstract
In political discourse metaphors are frequently employed for persuading and manipulating the public. The aim of our research is to show whether there are differences in the use of source domains of conceptual metaphors among Croatian politicians in comparison with American and Italian politicians. The corpus of our research consists of political newspaper articles and interviews from Croatian, American and Italian daily newspapers (Jutarnji list, Večernji list, Corriere della Sera, Repubblica, ABC, USA Today and The New York Times), downloaded from newspaper archives. We can conclude that metaphorical expressions vary from language to language, but often the same metaphorical expressions appear in all languages. Expressions that frequently recur are victory, attack, battle, race, defense, splay, stage and role. Except for two ontological metaphors in Croatian examples, we can say that there is no major difference in the source domains between Croatian, American and Italian political discourse.
Teachers Scoring and Grading of Students’ Responses to Tasks: The Ghanaian Basic School Experience
Authors: Anane Eric , Adu-Mensah Jephtar 
Published: April 2019

Abstract
This paper explored the scoring and grading practices of teachers in basic schools. The study sought to understand the various factors teachers take into account when scoring students’ responses to tasks in the classroom. The stratified sampling procedure was used to select 278 primary and junior high school teachers from whom data were collected for the study. In the descriptive analysis, the results revealed that teachers considered students’ behaviour such as punctuality, interest in subject and neatness of work presented, and number of questions attempted by a student, and awarded marks when grading. These academic and non-academic factors considered by teachers in this study during scoring and grading are consistent with the literature. In independent samples t-test analyses, primary school teachers did not differ significantly from their counterparts in the junior high schools in terms of factors they considered during the scoring and grading of students’ responses to tasks in the classroom. This study adds a circumstantial data to the existing debate on teacher classroom assessment practices.
Modeling and querying facts with period timestamps in data warehouses
Authors: Mahlknecht Giovanni , Dignös Anton , Kozmina Natalija 
Published: April 2019

Abstract
In this paper, we study various ways of representing and querying fact data that are time-stamped with a time period in a data warehouse. The main focus is on how to represent the time periods that are associated with the facts in order to support convenient and efficient aggregations over time. We propose three distinct logical models that represent time periods as sets of all time points in a period (instant model), as pairs of start and end time points of a period (period model), and as atomic units that are explicitly stored in a new period dimension (period∗ model). The period dimension is enriched with information about the days of each period, thereby combining the former two models. We use four different classes of aggregation queries to analyze query formulation, query execution, and query performance over the three models. An extensive empirical evaluation on synthetic and real-world datasets and the analysis of the query execution plans reveal that the period model is the best choice in terms of runtime and space for all four query classes.
