RESUMO

Objectives: To describe the characteristics and outcomes of COVID-19 cases in Jamaica and to explore the risk factors associated with severe COVID-19 from 9 March to 31 December 2020. Methods: A cross-sectional analysis of national surveillance data was conducted using confirmed COVID-19 cases in Jamaica. Definitions of a confirmed case, disease severity, and death were based on World Health Organization guidelines. Chi-square and Fisher exact tests were used to determine association with outcomes. Logistic regression models were used to determine predictors of severe COVID-19. Results: This analysis included 12 169 cases of COVID-19 (median age, 36 years; 6 744 females [ 55.4%]) of which 512 cases (4.2%) presented with severe disease, and of those, 318 patients (62.1%) died (median age at death, 71.5 years). Severe disease was associated with being male (OR 1.4; 95% CI, 1.2-1.7) and 40 years or older (OR, 6.5; 95% CI, 5.1-8.2). COVID-19 death was also associated with being male (OR, 1.4; 95% CI, 1.1-1.7), age 40 years or older (OR, 17.9; 95% CI, 11.6-27.7), and in the Western versus South East Health Region (OR 1.7; 95% CI, 1.2-2.3). Conclusions: The findings of this cross-sectional analysis indicate that confirmed cases of COVID-19 in Jamaica were more likely to be female and younger individuals, whereas COVID-19 deaths occurred more frequently in males and older individuals. There is increased risk of poor COVID-19 outcomes beginning at age 40, with males disproportionately affected. COVID-19 death also varied by geographic region. This evidence could be useful to other countries with similar settings and to policymakers charged with managing outbreaks and health.

[RESUMEN]. Objetivos. Describir las características y los resultados de los casos de COVID-19 en Jamaica y explorar los factores de riesgo asociados a la COVID-19 grave desde el 9 de marzo hasta el 31 de diciembre del 2020. Métodos. Se realizó un análisis transversal de datos nacionales de vigilancia a partir de los casos confirma- dos de COVID-19 en Jamaica. Las definiciones de caso confirmado, gravedad de la enfermedad y muerte se basaron en las directrices de la Organización Mundial de la Salud. Para determinar la asociación con los criterios de valoración se utilizó la prueba de χ2 y la prueba exacta de Fisher. Se usaron modelos de regresión logística para determinar los factores predictivos de la COVID-19 grave. Resultados. Se incluyeron en el análisis 12 169 casos de COVID-19 (mediana de edad, 36 años; 6 744 mujeres [55,4%]), de los que 512 (4,2%) fueron de enfermedad grave. De estos pacientes, 318 (62,1%) fall- ecieron (mediana de edad al morir, 71,5 años). Se observó una asociación de la enfermedad grave con el sexo masculino (OR de 1,4; IC del 95 %, 1,2-1,7) y con la edad igual o superior a 40 años (OR de 6,5; IC del 95 %, 5,1-8,2). La muerte por COVID-19 también mostró una asociación con el sexo masculino (OR de 1,4; IC del 95%, 1,1-1,7), con la edad igual o superior a 40 años (OR de 17,9; IC del 95%, 11,6-27,7) y con la Región de Atención de Salud Occidental en comparación con la Sudoriental (OR de 1,7; IC del 95%, 1,2-2,3). Conclusiones. Los resultados de este análisis transversal indican que los casos confirmados de COVID-19 en Jamaica correspondieron una mayor probabilidad a mujeres y personas más jóvenes, mientras que las muertes por COVID-19 fueron más frecuentes en varones y personas de mayor edad. Hay un mayor riesgo de evolución desfavorable de la COVID-19 a partir de los 40 años, que afecta de manera desproporcionada a los varones. Las muertes por COVID-19 también variaron según la región geográfica. Esta evidencia podría ser de utilidad para otros países con entornos similares y para los responsables de la formulación de políticas en materia de gestión de brotes y salud.

RESUMO

SUMMARY: The aim of this study was to determine the sensitivity of different methods of partialization, in terms of different body component indices in relation to indicators of strength and explosiveness. The research involved 187 subjects who were divided into two groups based on sex. This research consisted of measuring body composition characteristics by multichannel bioimpedance analysis (BIA) InBody 720, as well as contractile characteristics of different muscle groups with tenziometric Dinamometry method. Based on the results of the factor analysis we found that regardless of the sex the most sensitive variable for partialization of absolute body isometric strength variable (ABiS) is partialization by allometric scaling (0.964 for females and 0.947 for males explained factor variance). However, in the case of absolute body isometric explosiveness (ABiE), the results of this study have demonstrated that partialization relative to skeletal muscle mass according to the body longitudinality - skeletal muscle mass index (SMMI) is the methodological choice disregarding the sex (0.982 for females and 0.980 for males explained factor variance). The results of the study have shown that for the purpose of scaling the maximal strength relative to body composition, the allometric method can be considered as a choice, while for the partialization of maximal isometric explosiveness skeletal muscle mass index is the best choice insensitive of the sex.

El objetivo de este estudio fue determinar la sensibilidad de distintos métodos de parcialización, en términos de diferentes índices de componentes corporales en relación a los indicadores de fuerza y explosividad. En la investigación participaron 187 sujetos que se dividieron según el sexo en dos grupos. Esta investigación consistió en medir las características de composición corporal mediante análisis de bioimpedancia multicanal (BIA) InBody 720, así como las características contráctiles de diferentes grupos musculares con el método de Dinamometría tenciométrica. Con base en los resultados del análisis factorial, encontramos que, independientemente del sexo, la variable más sensible para la parcialización de la variable de fuerza isométrica corporal absoluta (ABiS) fue la parcialización mediante escala alométrica (0,964 para las mujeres y 0,947 para los hombres). Sin embargo, en el caso de la explosividad isométrica corporal absoluta (ABiE), los resultados de este estudio han demostrado que la parcialización relativa a la masa del músculo esquelético según la longitudinalidad del cuerpo - índice de masa del músculo esquelético (SMMI) es la opción metodológica sin tener en cuenta el sexo (0,982 para las mujeres y 0,980 para los hombres). Los resultados del estudio han demostrado que para escalar la fuerza máxima en relación con la composición corporal, el método alométrico puede considerarse como una opción, mientras que para la parcialización de la explosividad isométrica máxima, el índice de masa del músculo esquelético es la mejor opción independiente del sexo.

RESUMO

En Colombia, el Decreto 1421 de 2017 reconoce a la familia como actor esencial en la participación efectiva del estudiantado con discapacidad. Se ofrece una reflexión sobre las barreras que las familias enfrentan al tratar de cumplir con las obligaciones enunciadas en esta normativa, y se proponen estrategias para incrementar su involucramiento. Las barreras actitudinales, físicas, comunicativas y sociales que afrontan las familias dificultan el éxito escolar de niños, niñas y adolescentes con discapacidad. Asimismo, el escaso reconocimiento de la diversidad lingüística, la geografía y el conflicto armado minimizan la presencia de estudiantes con discapacidad y sus familias en entornos escolares de algunas regiones del país. De otra parte, el enfoque unidireccional y centrado en las limitaciones del estudiante dificulta la participación y cumplimiento de las obligaciones escolares en algunos es-tablecimientos educativos. La generación de políticas con enfoque territorial que visibilicen las necesidades regionales y promuevan las diferencias lingüísticas y culturales, así como la toma de conciencia, el acompañamiento psicosocial, el trabajo colaborativo y la generación de espacios de empoderamiento, desde una perspectiva de derechos, pueden favorecer el rol de las familias para el logro de la inclusión y la equidad en la educación.

In Colombia, Decree 1421 of 2017 recognizes the family as a fundamental stakeholder in facilitating the meaningful participation of students with disabilities. This article offers insightful considerations regarding the challenges families face in fulfilling the obligations outlined by this regulation, and several strategies to enhance their engagement. The attitudinal, physical, communicative, and social barriers they encounter significantly impede children and adolescents with disabilities' academic success. In specific regions of the country, poor recognition of linguistic diversity, geography and armed conflict minimize the presence of students with disabilities and their families in school settings. Furthermore, the unidirectional approach focused on the student's limitations makes participating and fulfilling school obligations in some educational establishments difficult. The creation of territorial-focused policies that bring regional needs to the forefront and promote linguistic differences, coupled with fostering awareness, psychosocial support, collaborative work, and the development of empowering spaces from a rights-based perspective, may favor the role of families in achieving inclusion and equity in education

Este artigo oferece uma reflexão sobre as barreiras que as famílias enfrentam no cumprimento das obrigações estabelecidas por esta normativa e propõe algumas estratégias para aumentar sua participação. As barreiras atitudinais, físicas, comunicativas e sociais que as famílias enfrentam dificultam o sucesso escolar de crianças e adolescentes com deficiência. Em algumas regiões, a falta de reconhecimen-to da diversidade linguística, a geografia e o conflito armado minimizam a presença de estudantes com deficiência e suas famílias nos ambientes esco-lares. Por outro lado, a perspectiva unidirecional, focada nas limitações dos estudantes, dificulta a participação e o cumprimento das obrigações escolares em algumas instituições educacionais. A geração de políticas com enfoque te-rritorial, que visibilizem as necessidades regionais e promovam as diferenças linguísticas, bem como a conscientização, o acompanhamento psicossocial, o trabalho colaborativo e a geração de espaços de empoderamento, desde uma perspectiva de direitos, podem favorecer o papel das famílias para alcançar a inclusão e a equidade na educação.

RESUMO

SUMMARY: The Olympic Games always offer great interest when it comes to water polo. Currently, many selections have an approximate quality and details determine who will win. Prior to the tournament the authors wanted to verify body composition and anthropometric characteristics of players of the three national teams, Serbia, the United States of America (USA) and Montenegro. The purpose of this research was to determine the differences in body composition and anthropometric characteristics between the water polo players of the national team of Serbia and Olympic champion in Tokyo 2021, the national team of USA which took sixth place and the national team of Montenegro, which took the eighth place. Body mass index, fat percentage and muscle mass (body composition variables) were evaluated by Bioelectric Impedance type MC-980 and body height, body weight, triceps skinfold, biceps skinfold, skinfold of the back, abdominal skinfold, upper leg skinfold, lower leg skinfold (other anthropometric characteristics) were evaluated by an anthropometer and a calliper. ANOVA showed that there was a statistically significant difference in fat percentage. The LSD post hoc test showed statistically significant differences between the water polo players of the Montenegrin national team (13.33 %) compared to the water polo players of the USA national team (16.67 %). It can be stated that water polo players from Montenegro had a statistically significantly lower fat percentage than water polo players from the USA and a lower level of fat than water polo players from Serbia, though this was not statistically significant. Although the fat percentage is a disruptive factor with athletes, it had no effect on the result at the Olympic Games in Tokyo, because Serbia eventually won the gold medal, the USA obtained sixth place, and Montenegro eighth place. It means that some other abilities influenced the results at the Tokyo Olympics in water polo, for example tactical, physical, psychological, technical... which is to be shown by some other research.

Los Juegos Olímpicos siempre ofrecen un gran interés en lo que respecta al waterpolo. Actualmente, muchas selecciones tienen una calidad aproximada y los detalles determinan quién ganará. Antes del torneo, los autores deseaban comprobar la composición corporal y las características antropométricas de los jugadores de las tres selecciones nacionales: Serbia, Estados Unidos (EE.UU.) y Montenegro, que siempre tienen las mayores ambiciones en las grandes competiciones. El propósito de esta investigación fue determinar las diferencias en composición corporal y características antropométricas entre los jugadores de waterpolo de la selección nacional de Serbia, que fue campeona olímpica en Tokio 2021, la selección nacional de Estados Unidos que ocupó el sexto lugar y la selección nacional de Montenegro, que acabó octavo. El índice de masa corporal, el porcentaje de grasa y la masa muscular (variables de composición corporal) se evaluaron mediante Impedancia Bioeléctrica tipo MC-980 y la altura corporal, el peso corporal, el pliegue del tríceps, el pliegue del bíceps, el pliegue de la espalda, el pliegue abdominal, el pliegue de la parte superior de la pierna y la parte inferior de la pierna. Los pliegues cutáneos (otras características antropométricas) fueron evaluados mediante un antropómetro y un calibrador. ANOVA mostró que había una diferencia estadísticamente significativa en el porcentaje de grasa. La prueba post hoc de LSD mostró diferencias estadísticamente significativas entre los jugadores de waterpolo de la selección nacional de Montenegro (13,33 %) en comparación con los jugadores de waterpolo de la selección de Estados Unidos (16,67 %). Se puede afirmar que los jugadores de waterpolo de Montenegro tenían un porcentaje de grasa estadísticamente significativamente menor que los jugadores de waterpolo de EE. UU. y un nivel de grasa más bajo que los jugadores de waterpolo de Serbia, lo que no es estadísticamente significativo. Aunque el porcentaje de grasa es un factor perturbador para los atletas, no tuvo ningún efecto en el resultado de los Juegos Olímpicos de Tokio, ya que al final Serbia ganó la medalla de oro, Estados Unidos quedó en sexto lugar y Montenegro en el octavo lugar. Esto significa que en los resultados de los Juegos Olímpicos de Tokio en el waterpolo influyeron otras habilidades, por ejemplo tácticas, físicas, psicológicas y técnicas, tal como lo demostrarán investigaciones a futuro.

RESUMO

Abstract Solid dispersions (SDs) of ursolic acid (UA) were developed using polyvinylpyrrolidone K30 (PVP K30) in combination with non-ionic surfactants, such as D-α-tocopherol polyethylene glycol 1000 succinate (TPGS) or poloxamer 407 (P407) with the aim of enhancing solubility and in vitro release of the UA. SDs were investigated using a 24 full factorial design, subsequently the selected formulations were characterized for water solubility, X-ray diffractometry (XRD), differential scanning calorimetry (DSC), particle diameter, scanning electron microscopy, drug content, physical-chemical stability and in vitro release profile. SDs showed higher UA water-solubility than physical mixtures (PMs), which was attributed by transition of the drug from crystalline to amorphous or molecular state in the SDs, as indicated by XRD and DSC analyses. SD1 (with P407) and SD2 (with TPGS) were chosen for further investigation because they had higher drug load. SD1 proved to be more stable than SD2, revealing that P407 contributed to ensure the stability of the UA. Furthermore, SD1 and SD2 increased UA release by diffusion and swelling-controlled transport, following the Weibull model. Thus, solid dispersions obtained with PVP k-30 and P407 proved to be advantageous to enhance aqueous solubility and stability of UA.

RESUMO

African mahogany species (Khaya spp.) have proven to be promising in the Brazilian forestry scenario, replacing native mahogany owing to their medium-fast growth and relevant timber value. This study aimed to carry out forest inventory and assessments of a Khaya grandifoliola plantation in the first years after planting, test hypsometric models to describe tree growth, and identify the maximum commercial stem yield (i.e., greater than 6 m in height). The stand was located in the municipality of Piracanjuba (GO), where seedlings of seed origin were used. Twenty random plots with a 15 m radius were allocated, and the total height (HT), stem height (HS), diameter at breast height (DBH), crown area, and forest canopy were measured. Four hypsometric models were employed in this study. The best equation was selected based on determination coefficients and standard errors. Further, the models were cross-validated to evaluate predictability and bias. At four years of planting, the largest class of HS was found to range from 3.1 to 4.1 m, and most trees had a DBH ranging from 0.084 to 0.126 m. The percentage of trees with stems > 6 m was 8.35%. The linear model ensured more consistent results for estimating HT, while the quadratic and Weibull models led to more consistent results for HS. By using models, stem measurements can be measured based on DBH, ultimately aiding the selection of stem management strategies for the growth of forests with greater commercial value.

RESUMO

Edible films have been studied mainly as primary packaging materials, but they may be used as barrier layers between food components, e.g., by reducing the moisture migration between components with contrasting water activities. Since edible films are part of the food itself, components adding sensory appeal (e.g., fruit purees) are usually desirable. The objective of this study was to develop a film to be applied as a moisture barrier between nachos and guacamole. Ten film formulations were prepared according to a simplex centroid design with three components-a polysaccharide matrix (consisting of a 5:1 mixture of bacterial cellulose-BC-and carboxymethyl cellulose), tomato puree (for sensory appeal), and palm olein (to reduce hydrophilicity)-and produced by bench casting. The film with the highest palm olein content (20%) presented the lowest water vapor permeability, and its formulation was used to produce a film by continuous casting. The film was applied as a layer between nachos and guacamole, and presented to 80 panelists. The film-containing snack was preferred and considered as crispier when compared to the snack without the film, suggesting that the film was effective in reducing the moisture migration from the moist guacamole to the crispy nachos.

RESUMO

RESUMEN El cumplimiento de las metas de los Objetivos de Desarrollo Sostenible y el fortalecimiento de las competencias para ser ciudadanos globales plantea grandes desafios a las naciones y especialmente, a sus sistemas educativos. En este contexto, se propone el diseno de un modelo de coordenadas curriculares dirigido a la formación de competencias para el desarrollo sostenible y la ciudadanía mundial, dentro de la Institución Universitaria Pascual Bravo (Colombia). Desde un enfoque Qualitativo, con alcance descriptivo y el diseno de teoria fundamentada, se realizó una caracterización que devela la necesidad de avanzar en modelos curriculares de educación superior, cuya base sean los conocimientos teóricos y prácticos a fin de promover el desarrollo y los estilos de vida sostenible. A partir de ahi, se plantea modelo de gestión curricular que permita reflexionar sobre la importancia de articular dichas competencias a los propósitos misionales. Se concluye que, con su aplicación, la comunidad académica puede adoptar la herramienta teórica y establecer un diseno que favorezca la actualización curricular con enfoque hacia el desarrollo sostenible.

ABSTRACT The fulfillment ofthe targets of the Sustainable Development Goals and the strengthening of the competencies to be global citizens brings out great challenges to the nations and, especially to their educational systems. In this context, the design of a model of curricular coordinates aimed at the formation of skills for sustainable development and world citizenship, within la Institución Universitaria Pascual Bravo (Pascual Bravo University Institution for its English conversion) (Colombia), is proposed. From a qualitative approach, with a descriptive scope and grounded theory design, a characterization was carried out that reveals the need to advance in higher education curricular models, whose base is theoretical and practical knowledge in order to promote the development and sustainable life styles. From there, a curricular management model is proposed that allows to reflect on the importance of articulating these competencies to the missionary purposes. It is concluded that, with its application, the academic community can adopt the theoretical tool and establish a design that favors curricular updating with a focus on sustainable development.

RESUMO O cumprimento das metas dos Objetivos de Desenvolvimento Sustentável e o reforço das competéncias para a cidadania global representam grandes desafios para as nações e, especialmente, para os seus sistemas educativos.

A partir de uma abordagem qualitativa, com um âmbito descritivo e uma conceção teórica fundamentada, foi realizada uma caracterização que revela a necessidade de avançar nos modelos curriculares do ensino superior cuja base o conhecimento teórico e prático, a fim de promover o desenvolvimento sustentável e os estilos de vida. Nesta base, é proposto um modelo de gestão curricular que permite refletir sobre a importância de articular estas competéncias com os objetivos da missão da instituição. Conclui-se que, com a sua aplicação, a comunidade académica pode adotar a ferramenta teórica e estabelecer um desenho que favoreça a atualização do currículo com enfoque no desenvolvimento sustentável.

RESUMO

Background: Actinobacillus pleuropneumoniae (A. pleuropneumoniae) is one of the most important bacterial respiratory pathogens. It is the only etiological agent of porcine pleuropneumonia (PPP) or it appears as a secondary bacterial infection in the swine respiratory disease complex (PRDC). In Serbia, apart from the identification of serotype 2, no tests have been performed to establish the presence of other A. pleuropneumoniae serotypes in the pig population. The aim of this study was to perform genotyping of A. pleuropneumoniae isolates originating from pig farms in Serbia by apx genes and using multiplex polymerase chain reaction (mPCR). Materials, Methods & Results: Isolates of A. pleuropneumoniae examined in this study were obtained from lungs with macroscopically visible alterations characteristic of a A. pleuropneumoniae. A total of 46 isolates were examined. They were extracted from the lung tissue samples of pig carcasses from 9 farms across different parts of Serbia. Genotyping of isolates was performed in the previously described manner. Briefly, 5 pairs of oligonucleotide primers were used for amplification of 4 different apx genes which encode synthesis of exotoxins (ApxI , ApxII , ApxIII i ApxIV) characteristic for all A. pleuropneumoniae serotypes and biovars. Amplification of appropriate genome parts was performed with a reaction chain polymerase (PCR) in multiplex (m) format using appropriate diagnostic kits to extract DNA from bacteria and perform mPCR reaction. The results of genotyping of 46 isolates of A. pleuropneumoniae indicate the existence of a large number of different serotypes of A. pleuropneumoniae on the studied farms or that different serotypes of this microorganism circulate in the pig population in Serbia. In addition to the detection of dominant serotype 2, which was established on 7 farms, of which in 4 farms it was the only detected serotype, in the examined pig population the presence of serotypes 3, 5, 6, 7 and 9 was also found. Furthermore, the presence of 2 different serotypes of A. Pleuropneumoniae was also detected on 3 farms; on the first farm serotypes 2 and 3, on the second farm serotypes 2 and 6, and on the third farm serotypes 2 and 7. Discussion: Although the research was done with a relatively small number of isolates of A. pleuropneumoniae, comparing the obtained results with the results on the presence and prevalence of appropriate serotypes from other countries, we concluded that there is significant diversity of this pathogen in the pig population in farms of Serbia. Detection of different serotypes of A. pleuropneumoniae in the pig population and the presence of several different serotypes on 1 farm was established for the very first time in Serbia. All isolates from our study can be characterized as highly virulent, considering that the clinical symptoms, pathological findings and the results of bacteriological examination indicated A. pleuropneumoniae to be the cause of animal death. Like in the neighbouring countries, the strongly pathogenic serotype 9 and the less pathogenic serotype 2 are the most frequently identified causative agents of porcine pleuropneumonia in the Autonomous Province of Vojvodina, Republic of Serbia. The necessity to establish the presence of all A. pleuropneumoniae serotypes in the pig population, and in particular to determine the presence of different serotypes on individual farms, is crucial for several reasons: making a definitive e diagnosis; development of prophylactic strategies for medicines; implementation of immunoprophylactic vaccination.

RESUMO

Background: Uterine torsion is one of many causes of dystocia in sheep. Failure in performing of wright-time diagnostic procedures and treatment by certain obstetric procedures, can result with death of both fetus and ewe. There is sufficient knowledge about risk factors which could contribute to the occurrence of uterine torsion in sheep, but there is insufficient knowledge about measures for prevention of uterine torsion. The aim of this study was to evaluate the effects of performing incorporative uteropexy as potential method for prevention of uterine torsion. Cases: This research was part of the experimental research of changes in the anterior presentation in sheep fetuses due to their ventro-sacral position in the 2nd half of gestation. At the same sheep farm where afore mentioned research was conducted, the farmer has reported the death of 3 pregnant ewes. In all of 3 animals, torsion of the uterus was diagnosed by patho-anatomical examination. This study was conducted on 6 ewes. All of the animals were in the period around the 100th day of pregnancy at the time of clinical examination. The exact day of pregnancy was not determinated because of free mating in the herd. Confirmation of pregnancy in all of 6 ewes was performed by ultrasound examination. Uniparous pregnancy was found in all of 6 ewes. The entire surgical procedures were performed in the field conditions. Laparotomy was performed in the animals positioned in the left lateral recumbency. Surgical procedure of incorporative uteropexy was performed during the closure of muscle layers of abdominal wall. In need for experimental research of changes in the anterior presentation in sheep fetuses due to their ventro-sacral position in the 2nd half of gestation, 14 days after surgical procedures were conducted, all of sheep were positioned by assistants into a sitting position so that their trunks were vertical to the ground and kept in that position for 2 min. Ultrasound examination of surgical place of uteropexy confirmed that, in all of animals, uteruses were in place of surgical procedures. All of 6 ewes included in this study lambed naturally. One of 6 sheep was sent for economic exploitation on the 14th day after lambing. At the slaughter line, the abdominal wall was evaluated at the site where the incorporative uteropexy was performed. Patho-anatomical examination revealed tissue adhesions at the junction of the uterine horn with the abdominal wall. Discussion: Postsurgical tissue adhesions develop during normal healing process of tissue. According to our knowledge, previous studies do not mention effective measures that could contribute to the prevention of uterine torsion in sheep, but attention is focused on prompt diagnosis and treatment of the disease. According to the results of this study, postsurgical tissue adhesions were developed and confirmed by patho-anatomical examination in 1 sheep. Other 5 sheep were not economically exploited or sacrificed, and no studies were performed to establish the presence of postsurgical tissue adhesions. In conclusion, it could be said that incorporative uteropexy could be considered as preventive procedure in order to avoid the development of uterine torsion in ewes which have shown a history of this pathology, but also in ewes with identified risk factors for the disease. In future studies, it is necessary to identify more parameters which will contribute to identification of sheep which have high risk factors to obtain the torsion of uterus. Also, it is necessary to use non-invasive methods of clinical diagnostics, primary ultrasound diagnostic, to evaluate the area of incorporative uteropexy in order to assess newly formed tissue adhesions as well as to assess the vitality of fetus. It is necessary to follow the lambing process of ewes with incorporated uterus, and to provide medical assistance to the animals if complications occur during the lambing time.

RESUMO

Abstract Carbon tetrachloride (CCl4) represents an organic chemical that causes reactive oxygen species derived organ disturbances including male infertility. Melatonin (MLT) is a neurohormone with strong antioxidant capacity, involved in numerous physiological processes. In this study we evaluated the capability of MLT, administered in a single dose of 50 mg/kg, to preserve the testicular tissue function after an acute administration of CCl4 to rats. The disturbance in testicular tissue and the effects of MLT after CCl4 exposure were estimated using biochemical parameters that enabled us to determine the tissue (anti)oxidant status and the intensity of arginine/nitric oxide metabolism. Also, the serum levels of testosterone and the histopathological analysis of tissue gave us a better insight into the occurring changes. A significant diminution in tissue antioxidant defences, arginase activity and serum testosterone levels, followed by the increased production of nitric oxide and extensive lipid and protein oxidative damage, was observed in the CCl4-treated group. The application of MLT after the CCl4 caused changes, clearly visible at both biochemical and histological level, which could be interpreted mainly as a consequence of general antioxidant system stimulation and a radical scavenger. On the other hand, the application of MLT exerted a limited action on the nitric oxide signalling pathway.

RESUMO

SUMMARY: This study aimed to consolidate data regarding body height, body weight, body mass index, and nutrition status of the entire young male population from the Municipality of Bijelo Polje in order to estimate trends from 1979 to 1987. The sample of respondents includes 10,954 young males divided into nine groups. The measurement sample includes body height, body weight, and body mass index based on two previous measures. The descriptive statistics were expressed as a mean and standard deviation for each variable, while the analysis of nutrition status was done based on body mass index (underweight, normal weight, pre-obese, obese). The results showed that a secular trend in the observed study period is not visible regarding body height, body weight, and body mass index. The contribution of this study is reflected in the fact that there were no previously published data for this period and this municipality; the data can significantly aid in monitoring the secular trends throughout Montenegro.

SUMMARY: This research aimed to determine the differences between the junior (U18) water polo players of five Croatian and one Montenegrin clubs in the anthropometric characteristics and body composition. The first sample of the subjects consisted of 14 players of the water polo club Mladost average age 17.57±0.65, the second sample consisted of 11 players of the water polo club Sibenik (17.82±0.65), the third sample consisted of 13 players of the water polo club Primorje (17.23±1.01), the fourth sample consisted of 15 players of the water polo club Mornar (17.13±0.64), the fifth sample consisted of 13 players of the water polo club Medvescak (17.92±0.76) and the sixth sample consisted of 10 players of the water polo club Jadran Herceg Novi (Montenegro) (17.70±1.34). In the 2010-11 season, these clubs participated in Regional Water Polo League, commonly known as the Regional League or Adriatic League in Southeast Europe. The measurements was conducted in the competition season in the period September-December 2010, at sports centers and swimming pools of water polo clubs that participated in the research. Anthropometric characteristics and body composition were evaluated using a battery of 12 variables: body height, body weight, arm length, arm span, leg length, foot length, chest skinfold, triceps skinfold, back skinfold, abdominal skinfold, upper leg skinfold and body mass index. The standard central and dispersion parameters of all variables were calculated. The significance of the differences between the water polo players of six teams in the variables for assessing anthropometric characteristics and body composition were determined using ANOVA and an LSD Post Hoc test.Based on the central and dispersion parameters, it can be stated that the values of all the variables are highly similar to all of the water polo players of these six clubs. The ANOVA test found that the water polo players of the six international clubs do not have statistically significant differences in the variables for assessing anthropometric characteristics and body composition.

RESUMO

SUMMARY: The purpose of this study was to describe the anthropometric characteristics and body composition of elite handball and volleyball players from the Serbian national league as well as to make comparisons between them. Sixty males were enrolled, divided into three groups: 15 handball players, 14 volleyball players, and 31 healthy sedentary subjects. All subjects were assessed for the anthropometric measures required for the calculation of body composition variables, using the standardized procedures recommended by established literature. Data were analysed using SPSS, and the descriptive statistics were expressed as a mean (SD) for each variable, while the ANOVA and LSD Post Hoc tests were carried out to detect the effects of each type of sport. The results showed there was no significant difference for body weight and body mass index, nor were there any differences for the bone contents of bodies among the groups, while significant differences were found for body height, as well as for muscle and fat content of body among the groups. These findings may give coaches from the region better working knowledge and enable them to follow recent selection process methods and to be more careful during talent identification.

RESUMO

SUMMARY: The purpose of this research is to determine a regression equation for the estimation of stature from sitting height measurements in the Southern Region of Kosovo. This research was carried out on 225 individuals (120 male and 105 female). The anthropometric measurements were taken according to the ISAK protocol. The relationships between standing height and sitting height measurements were determined using simple correlation coefficients at a 95 % confidence interval. A comparison of means of standing height and sitting height between genders was performed using a t-test. After that, a linear regression analysis was carried out to examine the extent to which sitting height can reliably predict standing height. The results revealed that Southern Kosovan males are 178.61±5.73 cm tall and have a sitting height of 94.05±3.09 cm, while Southern Kosovan females are 165.33±4.46 cm tall and have a sitting height of 89.34±2.50 cm. The results have shown that both genders made Southern-Kosovans a tall group, taller than the general Kosovan population. This research study confirmed that sitting height reliably predicts stature in both genders of adolescents in the Southern Region of Kosovo and revealed a very useful finding for physical anthropologists and experts from related fields.

RESUMEN: El objetivo de este trabajo fue determinar una ecuación de regresión para la estimación de la estatura a partir de mediciones de la altura sentada en la Región Sur de Kosovo. La investigación se realizó en 225 individuos (120 hombres y 105 mujeres). Las medidas antropométricas se tomaron según el protocolo ISAK. Se determinaron las relaciones entre la altura de pie y la altura sentada utilizando coeficientes de correlación simples con un intervalo de confianza del 95 %. Se realizó una comparación de las medias de la altura de pie y la altura sentada entre sexos mediante una prueba t. Además, se llevó a cabo un análisis de regresión lineal para la estimar la confiabilidad de la medición de altura de pie, considerando la altura sentada. Los resultados indican que los varones del sur de Kosovo miden 178,61 ± 5,73 cm de altura y tienen una altura sentada de 94,05 ± 3,09 cm, mientras que las mujeres miden 165,33 ± 4,46 cm de altura y tienen una altura sentada de 89,34 ± 2,50 cm. Los resultados han demostrado que ambos sexos kosovares del sur son más altos que la población general de Kosovo. Este estudio confirmó que la altura sentada predice de manera confiable la estatura de ambos sexos en adolescentes de la región sur de Kosovo y reveló un hallazgo útil para los antropólogos físicos y los expertos de áreas relacionadas.

RESUMO

The aim of this research was to determine the differences between the cadets (U15) water polo players of national teams of Montenegro and Croatia in the body composition and anthropometric characteristics. A sample of 32 subjects was divided into two sub-samples. The first sub-sample of the subjects was consisted of 16 water polo players of Montenegro national team of the average age 14.69±.48, the vice champions on the European Championships in Burgas (Bulgaria) 2019, while the other sub-sample was consisted of 16 water polo players of national team of Croatia of the average age of 14.75±.45, who occupied the eighth position on the European Championships in Burgas (Bulgaria) 2019. Water polo players were tested at the final preparations just before the European championship. Body composition and anthropometric characteristics were evaluated by a battery of 11 variables: body height, body weight, triceps skinfold, biceps skinfold, skinfold of the back, abdominal skinfold, upper leg skinfold, lower leg skinfold, body mass index, fat percentage and muscle mass. The standard central and dispersion parameters of all variables were calculated. The significance of the differences between the water polo players of two national teams in the variables for assessing body composition and anthropometric characteristics was determined by a t-test for independent samples. It was found that there are statistically significant differences in five variables, in three variables at p<0.01 (body height, triceps skinfold and biceps skinfold), and in two variables at p<0.05 (upper leg skinfold and muscle mass). It can be stated that the water polo players of Montenegro have statistically significantly higher triceps skinfold, biceps skinfold and upper leg skinfold, and statistically significantly lower body height and muscle mass than the water polo players of Croatia.

RESUMO

Resumen Este artículo muestra los resultados del proyecto de investigación/intervención, denominado "Significados y Sentidos del amor en parejas con historias de infidelidad", realizado en la Universidad Santo Tomas de Bogotá (Colombia). Se realizó una apuesta por la comprensión de los significados del amor en parejas que han tenido engaños y desilusiones amorosas asociadas a infidelidades, y la intervención psicoterapéutica para la reorganización de versiones novedosas del amor, la infidelidad y el ser pareja desde una perspectiva sistémica constructivista, socio construccionista y compleja. En esta investigación, participaron dos parejas cuyo motivo de consulta se relaciona con la infidelidad, se desarrollaron 5 escenarios narrativos conversacionales con cada una de ellas, empleando dispositivos de intervención tales como: la construcción de historias, las esculturas y las metáforas. Los principales hallazgos reconocen relatos matizados de los conyugues, por imágenes idealizadas de la pareja generando sentimientos de culpabilidad, historias asociadas al silencio y sometimiento como forma de solucionar los conflictos, la deconstrucción de historias de infidelidad para reconstruir la trama narrativa de la pareja desde aspectos particulares que conectan a los enamorados, y el acontecimiento de infidelidad como posibilidad de cambio.

Abstract This article shows the results of the research/intervention project titled "Meanings and senses of love in couples with a history of infidelity", carried out in the Santo Tomas University of Bogotá (Colombia). An effort was made to understand the meanings of love in couples who have suffered from deceit and disappointment in love associated with infidelity, and who have received psychotherapeutic intervention for the configuration of new versions of love, infidelity, and being a couple from a systemic-constructivist, social-constructionist, and complex perspective. Two couples whose reason for consultation was related to infidelity participated in this research, and five conversational narrative scenarios were developed with both of them, using intervention devices such as the construction of stories, sculptures, and metaphors. The main findings show stories from the spouses that are nuanced through idealized images of the couple that generates feelings of guilt; stories associated with silence and submission as a means to resolve conflicts; the deconstruction of infidelity stories to reconstruct the couple's narrative plot based on particular aspects that connect the lovers; and the event of infidelity as a possibility for change.
