Establece la incidencia del subtipo molecular de cáncer de mama en hallazgos mamográficos BIRADS 4 y 5, Hospital Nacional Guillermo Almenara 2017. El avance de los diferentes métodos diagnóstico, pero principalmente los de inmunohistoquímica, han contribuido a optimizar el abordaje de las variantes inmunofenotípicas del cáncer de mama. Al mismo tiempo, lo anterior ha conducido a caracterizar patrones específicos de comportamiento en relación a su capacidad de metastatizar dadas las diferencias moleculares. Las metástasis,por su parte, son evaluadas mediante varios métodos de imagen, lo que permite el estadiaje, así como la determinación del sitio de presentación. Además, también es factible evaluar el periodo libre de progression, por lo que todos estos factores son fundamentales en el manejo multidisciplinario de las pacientes afectadas con cáncer de mama. Por ello, sie...

La presente investigación tuvo como objetivos evaluar el diurético del zumo del fruto de Citrus limonium (limón) en ratas, se utilizaron 36 ratas albinas Cepa Holtzman quienes recibieron NaCl 0.9% 25 mL/kg, luego de 30 min los animales fueron separados en seis grupos de seis ratas cada grupo, y se procedió a la administración de los tratamientos: G1 SSF 2mL/Kg, 2G furosemida 10 mg/kg °, el 3G hidroclorotiazida 200 mg/Kg y 4G, 5G y 6G recibieron zumo de limón en volúmenes de 0.1, 0.25 y 0.5 mL/rata respectivamente, se encontró un porcentaje de rendimiento del zumo de 45%, así también la presencia de taninos y alcaloides, saponinas, esteroides triterpénicos y flavonoides. Se encontró mayor efecto diurético con el zumo de limón a dosis de 0,5 mL/rata. Concluyendo que el zumo del fruto de Citrus limonium (limón) tiene efecto diurético en ratas normales.

Adult and immature gastrointestinal parasites from 47 tayassuids (27 Tayassu pecari and 20 Pecari tajacu) hunted for human consumption at the Pilon Lajas Biosphere Reserve and Indigenous Territory, Bolivia, were identified. Parasite eggs and oocysts were identified by fecal flotation and sedimentation, while adult parasites were obtained from the digestive tract and collected through the Travassos method for morphometric identification. Four nematode species (Texicospirura turki, Monodontus aguiari, Eucyathostomum dentatum and Ascaris sp.), one cestode (Monienzia benedeni), one trematode (Stichorchis giganteus) and Eimeria spp. oocysts were detected. Parasites of the Ascaris genera were detected only in T. pecari while the rest of the parasites were found in both tayassuid species. This study provides the first report for these parasites in peccaries from Bolivia. Given the close contact...

“The Purpose in Life Test (PIL) is a measure of purpose in life widely used in many cultures and countries; however, cross-cultural assessments are scarce. The present study aimed to evaluate the cross-cultural measurement invariance of the PIL in the general population of seven Latin American countries (Colombia, Ecuador, El Salvador, Mexico, Paraguay, Argentina, and Uruguay). A total of 4306 people participated, selected by non-probabilistic convenience sampling, where Uruguay has the highest mean age (M = 41.8; SD = 16.6 years); while Ecuador has the lowest mean age (M = 24.6; SD = 7.8 years). Furthermore, in each country, there is a higher proportion of women (>60%) than men (<40%). Using Multi-Group Confirmatory Factor Analysis, the factorial structure does not show evidence of invariance among the included countries. However, based on the Multi-Group Factor Analysis Alignment, th...

“The aim was to test the cross-cultural measurement invariance of the PIL-SF in a sample of people from seven Latin American countries. Additionally, the characteristics of the PIL-SF items were evaluated and to assess the relationship between purpose in life, as measured by the PIL-SF, and fear of COVID-19. A total of 4306 people from seven Latin American countries participated in the study. The results indicated that the PIL-SF is invariant in the seven participating countries and, therefore, there is evidence that the items refect the purpose of life in the same way in all countries. This allows comparisons of purpose in life between countries that are free of bias, refecting the true diferences in how countries respond to items. From IRT, the discrimination parameters are adequate and indicate that the items cover a wide range of the purpose in life construct. The difculty paramete...
