SUMMARY: The aim of the study was to compare the proprioceptive deficit through the Joint position sense (JPS) and Force steadiness in patients with anterior cruciate ligament (ACL) bone-patellar tendon-bone graft (PTH) reconstruction 6 to 12 months post-surgery. Fifteen patients (13 men and 2 women, 25.5 ± 1.3 years) with ACL reconstruction with HTH autograft and 20 persons without ACL injury (19 men and 1 woman, 24.1 ± 0.8 years) participated. To assess knee joint position sensation, Joint position sense (JPS) was measured in three ranges: 0°-30°, 31°- 60° and 61°-90° and quadriceps strength sensation was assessed with the Force steadiness (FS) test at 15 % of maximal voluntary contraction (MVC), both tests performed 6 to 12 months post surgery. The results showed that there were no statistically significant differences in joint position sensation (JPS 0°-30°) (p=0.564) and 31°-60° (p=0.681), while in the range 61°-90° (p=0.003) there were statistically significant differences. In the quadriceps strength sensation measurements (FS at 15 % CVM) between the patients operated on ACL HTH technique and the control group there were no statistical differences (p= 0.987). The quadriceps strength sensation measured with the FS test at 15 % CVM would not present a deficit between 6 to 12 months in post- operated ACL patients when compared to subjects without injury or surgery of this ligament. It is concluded that the joint position sensation measured with the JPS test in three joint ranges of patients with ACL reconstruction HTH graft 6 to 12 months post surgery only showed alterations in the range of 61°- 90° when compared to the control group, indicating that the joint position sensation presents a deficit in this specific range.

RESUMEN: El objetivo del estudio fue comparar el déficit propioceptivo a través del Joint position sense (JPS) y Force steadiness en pacientes con reconstrucción del ligamento cruzado anterior (LCA) injerto hueso-tendón patelar-hueso (HTH) 6 a 12 meses postcirugía. Participaron 15 pacientes (13 hombres y 2 mujeres, 25,5 ± 1,3 años) con reconstrucción de LCA con autoinjerto HTH y 20 personas sin lesión del LCA (19 hombres y 1 mujer, 24,1 ± 0,8 años). Para evaluar la sensación de posición de la articulación de la rodilla se midió la Joint position sense (JPS) en tres rangos: 0°-30°, 31°-60° y 61°-90° y la sensación de fuerza del cuádriceps fue evaluada con la prueba Force steadiness (FS) al 15 % de la contracción voluntaria máxima (CVM), ambas pruebas realizadas 6 a 12 meses post cirugía. Los resultados mostraron que no hubo diferencias estadísticamente significativas en la sensación de la posición articular (JPS 0°-30°) (p=0.564) y 31°-60° (p=0.681), mientras que en el rango 61°-90° (p=0.003) existieron diferencias estadísticamente significativas. En las mediciones de sensación de fuerza del cuádriceps (FS al 15 % CVM) entre los pacientes operados de LCA técnica HTH y el grupo control no hubo diferencias estadísticas (p= 0.987) La sensación de la fuerza del cuádriceps medida con la prueba FS al 15 % CVM no presentaría déficit entre los 6 a 12 meses en pacientes post operados de LCA al ser comparados con sujetos sin lesión ni cirugía de este ligamento. Se concluye que la sensación de la posición articular medida con la prueba JPS en en tres rangos articulares de pacientes con reconstrucción de LCA injerto HTH 6 a 12 meses post cirugía sólo mostró alteraciones en el rango de 61°- 90° al ser comparado con el grupo control, lo cual indica que la sensación de la posición articular presenta un déficit en este rango específico.

Abstract High-throughput sequencing studies have shown the important role microbial communities play in the male reproductive tract, indicating differences in the semen microbial composition between fertile and infertile males. Most of these studies were made on human beings but little is known regarding domestic animals. Seminal bacteria studies made in stallions mostly focus on pathogenic bacteria and on their impact on reproductive technology. However, little is known about stallion commensal seminal microflora. That ultimately hinders our capacity to associate specific bacteria to conditions or seminal quality. Therefore, the aim of this study was to characterize the seminal microbial composition of 12 healthy, fertile stallion using next-generation sequencing. Hypervariable region V3 was chosen for bacterial identification. A total of nine phyla was detected. The most abundant ones were Bacteroidetes (46.50%), Firmicutes (29.92%) and Actinobacteria (13.58%). At family level, we found 69 bacterial families, but only nine are common in all samples. Porphyromonadaceae (33.18%), Peptoniphilaceae (14.09%), Corynebacteriaceae (11.32%) and Prevotellaceae (9.05%) were the most representative ones, while the Firmicutes phylum displayed the highest number of families (23, a third of the total). Samples showed high inter-subject variability. Findings previously described in other species notably differ from our findings. Families found in human such as Lactobacillaceae, Staphylococcaceae and Streptococcaceae only represented a 0.00%, 0.17% and 0.22% abundance in our samples, respectively. In conclusion, Porphyromonadaceae, Prevotellaceae, Peptoniphilaceae and Corynebacteriaceae families are highly represented in the seminal microbiome of healthy, fertile stallions. A high variation among individuals is also observed.

Abstract From 1981 to 2014, thirty countries fully or partially privatized their social security public mandatory pensions; as for 2018, eighteen countries had re-reformed and reversed pension privatization. This report analyses the failure of the private mandatory pensions to improve the security of income in old age and its low performance in coverage rates, benefit levels, administrative costs, transition costs, and negative social and tax impacts, among others.

Resumen Entre 1981 y 2014, unos 30 países privatizaron total o parcialmente sus sistemas de pensiones públicas obligatorias; en 2018 unos 18 países habían revertido las privatizaciones. Este informe analiza el fracaso de los sistemas de pensiones privadas obligatorias para mejorar la seguridad de ingresos en la vejez y su bajo desempeño en términos de cobertura, niveles de beneficios, costos administrativos, costos de transición e impactos sociales y fiscales negativos, entre otros.

Abstract The aim of this study was to compare the post-thaw distribution of motile sperm subpopulations, following simple or colloid centrifugation. A new analysis was used to evaluate the available number of sperm from each subpopulation after each centrifugation protocol. Frozen/thawed semen samples were divided into the following after-thawing treatments: uncentrifuged control (UDC), sperm washing (SW) and two colloid centrifugation procedures (Equipure, SLC-E, and Androcoll, SLC-A). Percentage of total and progressive motility (TM and PM), as well as sperm motility kinematics, distribution of motile sperm subpopulations, and recovery rates, were statistically compared among treatments. The SLC treatments showed higher (P < 0.001) TM and PM than UDC and SW. Following each SLC procedure, different percentages of the subpopulation with the most vigorous and progressive sperm (sP4) were obtained. SLC-A recovered a larger number of sperm belonging to sP4 than SLC-E, but not significantly higher than SW. From a practical point of view, sperm washing, the standard centrifugation procedure for equine semen processing, recovered the same amount of fast and progressive sperm as colloid centrifugation, apparently the best treatment according to traditional analysis. In conclusion, samples processed by SLC have higher motility percentages than SW and UDC but, after combining the available number of sperm, SLC and SW techniques are equally efficient in recovering sperm from the most vigorous, fast and progressive motile subpopulation (sP4).

Resumen Introducción y objetivos: En la actualidad la posibilidad de fabricación de implantes vasculares mediante la técnica de electrospinning ha ganado interés para vasos sanguíneos de diámetros pequeños. El potencial en aplicaciones vasculares reside en su capacidad de generar estructuras microporosas con gran área superficial. Sin embargo, poco se conoce del efecto de dicha microestructura y su espesor, tanto en las propiedades de transporte de masa como en la proliferación celular. El propósito de este trabajo es analizar la permeabilidad, la porosidad y el crecimiento celular en membranas electrohiladas para prótesis vasculares. Métodos: mediante electrohilado se fabricaron membranas para implantes de poliuretano con memoria de forma (Irogran) en dos espesores, muestra 0 entre 0,2 mm y 0,9 mm y muestra +1 entre 0,9 mm y 1,0 mm, sobre las cuales se sembraron fibroblastos cardiacos humanos por un periodo de incubación hasta de 10 días. La porosidad y permeabilidad se evaluaron mediante la norma ISO 7198 y la proliferación celular se analizó a través de microscopia óptica y electrónica de barrido (SEM). El número total de muestras fue 12 para cada espesor de referencia. El análisis de datos se llevó a cabo mediante una prueba tipo ANOVA. Resultados: las muestras +1 presentaron permeabilidad promedio de 55,5% menor que las 0, reducción de la porosidad de 10,24%, asociado a mayor crecimiento celular, evidenciado por sincitios celulares. Conclusiones: La variación de estructuras microporosas de gran área superficial para obtener implantes con la técnica de electrospinning, incide en el crecimiento celular y subsecuentemente en la permeabilidad y la porosidad, hecho que abre una gran oportunidad para su uso potencial en aplicaciones vasculares de diámetros pequeños.

Abstract Introduction and motivation: Nowadays, the possibility of engineering vascular grafts by means of electrospinning has attracted interest for small-diameter blood vessels. Potential vascular application lies in their ability to generate microporous structures with a big surface area. However, little is know about the effect of such microstructure and its thickness, both regarding mass transportation as well as cell proliferation. The motivation of this work is to analyse the permeability, porosity and cell growth in electrospun membranes for vascular grafts. Methods: by electrospinning membranes for grafts made of memory polyurethane foam were fabricated in two thicknesses, sample 0 between 0.2 and 0.9 mm and sample +1 between 0.9 and 1.0 mm, amongst which human cardiac fibroblasts were grown during an incubation period of up to 10 days. Porosity and permeability were assessed according to ISO 7198 and cell proliferation was analysed with scanning optical and electronic microscopy (SEM). Total sample number was 12 for each baseline thickness. Data analysis was conducted by ANOVA test. Results: +1 samples presented an average permeability that was 55.5% lower than the 0 samples, 10.24% decrease in porosity associated to bigger cell growth, evidenced by syncytial cells. Conclusion: The variation of microporous structures of great surface area in order to obtain grafts by means of electrospinning technique affects cell growth and subsequently their permeability and porosity, thus offering an opportunity for its potential use in small-diameter vascular applications.

ABSTRACT INTRODUCTION: Cutaneous leishmaniasis (CL) is a tropical disease that affects millions of individuals worldwide. The current drugs for CL may be effective but have serious side effects; hence, alternatives are urgently needed. Although plant-derived materials are used for the treatment of various diseases in 80% of the global population, the validation of these products is essential. Gelatin capsules containing dried Artemisia annua leaf powder were recently developed as a new herbal formulation (totum) for the oral treatment of malaria and other parasitic diseases. Here, we aimed to determine the usefulness of A. annua gel capsules in CL. METHODS: The antileishmanial activity and cytotoxicity of A. annua L. capsules was determined via in vitro and in vivo studies. Moreover, a preliminary evaluation of its therapeutic potential as antileishmanial treatment in humans was conducted in 2 patients with uncomplicated CL. RESULTS: Artemisia annua capsules showed moderate in vitro activity in amastigotes of Leishmania (Viannia) panamensis; no cytotoxicity in U-937 macrophages or genotoxicity in human lymphocytes was observed. Five of 6 (83.3%) hamsters treated with A. annua capsules (500mg/kg/day) for 30 days were cured, and the 2 examined patients were cured 45 days after initiation of treatment with 30g of A. annua capsules, without any adverse reactions. Both patients remained disease-free 26 and 24 months after treatment completion. CONCLUSION: Capsules of A. annua L. represent an effective treatment for uncomplicated CL, although further randomized controlled trials are needed to validate its efficacy and safety.

Muchos pesticidas han sido clasificados como cancerígenos, ya que su principal efecto es inducir daño estructural o funcional en el material genético. Los agricultores en su afán de erradicar las plagas de los cultivos exceden la cantidad sugerida, esto hace que queden residuos en partes de la planta. En el presente trabajo se evalúa el efecto genotóxico en linfocitos humanos, inducido por extractos de fresas fumigadas con y sin pesticidas. Para evaluar la actividad genotóxica se utilizaron las técnicas de ensayo cometa e intercambio de cromátidas hermanas, la toxicidad se determinó mediante la prueba exclusión con azul de tripano. Los resultados de los ensayos indicaron que existe un efecto genotóxico dependiente de la dosis, con un P<0.05 según la prueba Tukey. El extracto sin pesticidas comparado con el control negativo mostró diferencias no significativas con un P<0.05. Los resultados nos muestran la existencia de compuestos en el extracto de fresa fumigado con pesticidas. Posiblemente estos pesticidas son los que inducen las lesiones en el ADN de linfocitos humanos. Dado que la fresa es un producto de alto uso en nuestra región, el consumo de esta podría convertirse en un factor de riesgo para la población consumidora.

Many pesticides are classified as carcinogenic, because its main effect is to induce structural or functional damage to genetic material. Farmers in their desire to eradicate pests of crops exceed the suggested amount, this makes residues in plant parts. In this paper we evaluate the genotoxic effects in human lymphocytes induced by extracts of fumigated strawberry with and without pesticides. To evaluate the genotoxic activity, comet assay and sister chromatid exchange techniques were used; toxicity test was determined by trypan blue exclusion. The test results indicated that there is a dose-dependent effect, with P <0.05 according to Tukey test. The extract without pesticides compared to the negative control showed no significant differences with P <0.05. The results we all display the existence of compounds in strawberry extract sprayed with pesticides. Possibly these pesticides are agents that induce DNA damage in human lymphocytes. Because the strawberry is a product of high use in our region, the consumption of this could be a risk factor for the consumer population.

Introduction: During malaria infection, both parasite and host are under the effects of oxidative stress due to the increased production of reactive oxygen species, which can induce DNA damage by its genotoxic effects. Objective: To evaluate genotoxic effects in human lymphocytes in a cohort of patients with malaria from Medellin and Quibdó. Methods: We performed an observational cross sectional study in 100 individuals with malaria and 100 healthy controls. Patients infected with Plasmodium consulting the Institute Colombiano of Medicina Tropical of Medellin and the Hospital Ismael Roldán Valencia of Quibdó were included. Genotoxic effects (genetic damage) was analysed by electrophoresis using alkaline single cell gel (Commet assay). Results: The average of tail length of malaria samples (26.9 ± 9.8) was significantly higher than of controls (14.8 ± 3.2) (p < 0.01). Conclusion: In our study population, malaria infection was associated with increased genotoxicity, while other variables such as smoking, antimalarial treatment, and occupation were not.

Introducción: Durante la infección de la malaria, tanto el parásito como el hospedero están bajo los efectos de estrés oxidativo, dado que se aumenta la producción de especies reactivas del oxígeno, las cuales pueden inducir daños en el ADN debido a su gran efecto genotóxico. Objetivo: Evaluar el efecto genotóxico en linfocitos humanos en una cohorte de pacientes con malaria de Medellín y Quibdó. Métodos: Se realizó un estudio observacional transversal en 100 personas con malaria y 100 controles sanos. Se incluyeron pacientes infectados con Plasmodium, que consultaron en el Instituto Colombiano de Medicina Tropical de Medellín y el Hospital Ismael Roldán Valencia de Quibdó. Se realizó una valoración transversal del efecto (daño genético) mediante electro-foresis en gel de células individuales (ensayo Cometa). Resultados: El promedio de longitud de la cola de los pacientes (26,9 ± 9,8) fue significativamente mayor que la media de los controles sanos (14,8 ± 3,2) (p < 0,01). Conclusión: Se evidenció en la población de estudio que la infección por malaria generó genotoxicidad, no así variables como tabaquismo, tratamiento antimalárico y ocupación.

A longitudinal, prospective, observational and descriptive study was conducted in 40 women, treated at the doctor's office No. 26 of "Josué País García" University Polyclinic in Santiago de Cuba, from January 2011 to the same month of 2012, in order to identify the factors contributing to exclusive breastfeeding discontinuation. Among the analyzed variables were mother's age, chronic diseases, parity, socioeconomic status, education and complications in childbirth. In the case material, mothers who first discontinued breastfeeding were those between 15-19 years of age (42.5%), nulliparous (32.5%), with low socioeconomic status (50.0%) and primary education. It was demonstrated that complications during the childbirth influenced the discontinuation of this type of feeding.

Introducción. Los mutágenos contenidos en mezclas complejas presentan interacciones de sinergismo, aditivas o antagónicas. Se han desarrollado enfoques experimentales que permitan dilucidar el responsable de las interacciones en la mezcla. Objetivo. Desarrollar un diseño experimental para comprender los procesos que se llevan a cabo entre los compuestos presentes en las mezclas complejas. Materiales y métodos. Se expusieron linfocitos humanos a mezclas binarias de mutágenos B[a]P, DMBA, Trp-P-1 y MX durante una hora, con activación metabólica y sin ella. La viabilidad se evaluó con azul de tripano y, la genotoxicidad, con cometa alcalino. Resultados. Ningún hidrocarburo tuvo efecto con furanona. Con S9 y sin él, se observó que se presentaban interacciones tóxicas entre hidrocarburos. Se observó sinergismo sin S9 entre B[a]P y Trp-P-1 y, con actividad metabólica, entre DMBA y Trp-P-1. Sin S9 se observó interacción antagónica entre Trp-P-1 y DMBA y, con S9, entre Trp-P-1 y MX y entre MX y DMBA. Se observó un incremento dependiente de la dosis en la longitud de la cola. Hubo daño genotóxico medio y aumento de las células dañadas. Para todas las mezclas se pudo determinar la concentración mínima en la que se observaban efectos adversos y solo para algunas se determinó la concentración máxima en la cual no se observaron efectos adversos. Conclusión. Se hace un aporte para comprender los procesos que ocurren cuando en una mezcla hay presentes, al menos, dos mutágenos y se valida un modelo de análisis que permite dilucidar el compuesto que tiene efecto sobre otro. También, se demostró que según el tipo de compuestos en la mezcla, se tendrá o no un umbral de riesgo.

Introduction. Mutagens contained in complex mixtures can present synergistic interactions, either additive or antagonistic. Therefore, development of experimental approaches is necessary to elucidate which is the responsible agent for the effect in the mixtures. Objective. An experimental design was developed that allowed an understanding of the processes between the compounds of complex mixtures. Materials and methods. Human lymphocytes were exposed to binary mixtures of the mutagens B[a]P, DMBA, Trp-P-1 and MX for 1 hour with or without S9. Viability was assessed with trypan blue dye and the genotoxicity by the comet assay. Results. All of the hydrocarbon showed an effect with furanone. With and without S9, the most toxic interactions were observed between hydrocarbons. Synergistic interaction was observed without S9 between B [a] P and Trp-P-1 and between DMBA and Trp-P-1 with metabolic activity. Without S9 antagonistic interaction was observed only between Trp-P-1+DMBA, and with S9 between Trp-P-1+MX and MX+DMBA. It observed an increase dose dependent in tail length. Half the cultures showed genotoxic damage and increased cell damage. For each mixture, minimum concentrations were determined at which adverse effects are observed; for some only the maximum concentration was determined at which no adverse effects are observed. Conclusion. The processes between mutagens present in a mixture have become better understood, and the results validated an analytical model that determined which component had an effect on another. The results also showed that the type of compounds in the mixture determined whether or not a risk threshold was present.
