Estudios en restos óseos humanos en Patagonia Austral: de la morfología clásica a la morfometría geométrica
Authors: D'Angelo del Campo Manuel Domingo , Guichón Ricardo Anibal , González Martín Armando 
Published: August 2023

A finales del s. XVIII, pero fundamentalmente durante los ss. XIX y XX, se realizan los primeros trabajos craneométricos acerca de las poblaciones que habitaron Patagonia Austral (PA). En esta región, los primeros abordajes de corte tipologista dejaron paso a otra corriente centrada en la estadística multivariante y la síntesis evolutiva a partir de la década de 1980. A fin de abordar cómo ha cambiado la bioantropología de PA a lo largo del tiempo se realizó un diagnóstico acerca de la información que contienen 75 publicaciones morfométricas, desde el año 1937 hasta el año 2020. Los resultados muestran que, en las últimas décadas, se ha producido un incremento exponencial de las publicaciones sobre las poblaciones nativas de PA, centrándose fundamentalmente en el estudio craneano, observándose una preponderancia del abordaje geométrico en la última década. Sin embargo, el trato de los metadatos primarios y secundarios es deficiente; muestra de ello, son los términos utilizados para definir la procedencia de las muestras, los cuales son vagos y poco precisos. El conocimiento acerca de la disposición de los restos esqueléticos y la información aportada acerca de la datación suele ser insuficiente o difusa. Las deficiencias en la comunicación de datos y metadatos conducen a dificultades en la replicabilidad y verificabilidad, promoviendo redundancias, baja eficiencia, e incidiendo en una mala gestión de fondos públicos para investigación. Esperamos que el uso de bases de datos bibliográficas y morfométricas, así como diagnósticos periódicos como este ayuden a que la comunidad bioantropológica comience a reportar en sus publicaciones información relevante asociada a los individuos analizados.

Aims
Hypoalbuminemia was extensively used to diagnose malnutrition in older adults. Malnutrition was associated with mortality in elderly patients with cardiovascular diseases. The relationship between hypoalbuminemia and clinical outcomes in elderly patients with nonischemic dilated cardiomyopathy (NIDCM) remains unknown.

Methods
A total of 1058 consecutive patients with NIDCM (age ≥60 years) were retrospectively enrolled from January 2010 to December 2019. Univariate and multivariate analyses were performed to assess the association of hypoalbuminemia with clinical outcomes.

Results
Patients with hypoalbuminemia were older (69.29 ± 6.67 vs. 67.61 ± 5.90 years, P < 0.001) and had higher prevalence of in-hospital and long-term death than those without (6.9 vs. 1.7%, 50.7 vs. 35.2%, P < 0.001). Logistic regression analysis showed that hypoalbuminemia was significantly related to in-hospital death [odds ratio (OR): 4.334, 95% confidence interval (CI): 2.185–8.597, P < 0.001]. Kaplan–Meier survival analysis showed that patients with hypoalbuminemia had worse prognosis than those with nonhypoalbuminemia (log-rank χ
2 28.96, P < 0.001). After adjusting for age, serum creatinine, HDL-C, AST/ALT hypoalbuminemia, LVEF and diabetes, hypoalbuminemia remained an independent predictor for long-term death (hazard ratio 1.322, 95% CI 0.046–1.670, P = 0.019).

Conclusion
Hypoalbuminemia was associated with increased risk of in-hospital and long-term mortality in elderly patients with NIDCM.
Comparative evaluation of mechanical properties of short aramid fiber on thermoplastic polymers

Published: August 2023

Abstract
This study investigated the mechanical performance of short aramid fiber on polypropylene, polyethylene, polyamide 6, and polyamide 12. Extrusion, press molding, and CNC cutting methods were used in the production of composite samples. Tensile, three-point bending, drop weight and hardness tests of the composites were carried out. As the fiber volume fractions increased, the mechanical properties of the composites improved, but the most efficient fiber fractions for each matrix changed. To analyze the performance of the fibers in the matrix on the composites, scanning electron microscope (SEM) images of the fractured surfaces as a result of tensile and drop weight tests were examined. As the fiber volume fractions increased, the fiber deformation increased, and as a result, the mechanical performance of the composites was adversely affected. Analysis of variance (ANOVA) and F test were performed using signal/noise values to analyze in detail the effect of experimental parameters on output values. Finally, the results of a regression equation model were compared with the experimental readings. It was found to be in good agreement with the model and the results of the experiment.

Estudos demonstram a eficácia de bioinseticidas no controle do mosquito Aedes aegypti. Neste sentido, este estudo teve como objetivo avaliar o efeito larvicida de extratos de Allamanda cathartica (L.) Apocynaceae (alamanda), Chrysanthemum morifolium (L.) Asteraceae (crisântemo) e de Cinnamomum verum (L.) Laureaceae (canela doce) sobre larvas do mosquito A. aegypti. Para a produção dos extratos os materiais vegetais desidratados (50 g) foram extraídos com água (1000 ml) por decocção e maceração por cinco dias com etanol (90%). Os extratos aquosos e hidroalcóolicos liofilizados foram diluídos em água deionizada nas concentrações de 100, 500 e 1000 μg/ml e introduzidos em recipientes (n =3) contendo 20 larvas de A. aegypti no terceiro/quarto estágio larval. A atividade larvicida foi avaliada 72 h após os tratamentos. Os extratos aquosos de C. verum nas concentrações de 100, 500 e 1000 μg/ml apresentaram média de 83,86% de eficiência. Contudo, os extratos aquosos e hidroalcoólicos de C. morifolium apresentaram forte atividade larvicida com 100% de eficiência em todas as concentrações testadas. Os achados deste estudo revelam que os extratos de C. morifolium e C. verum são promissores larvicidas naturais e podem auxiliar no controle do mosquito vetor de arboviroses como, a dengue, febre amarela, Zika e chikungunya.

Urban afforestation consists of arboreal plant elements present in the city and is of fundamental importance for the quality of life of citizens. The study of the urban green area aims to support a better planning of a city seeking an environmental balance so that in the future it will minimize the effects caused by urbanization. Understanding the allometric patterns that govern the growth of trees in public areas is part of modern urban planning. The aim of the study was to determine the allometric patterns of trees located in public green areas in the city of Boa Vista, Roraima. The study was based on adult individuals with a diameter at breast height (DBH) greater than or equal to 10 cm, dispersed in three public squares and central flower beds of two avenues. In the floristic survey, there was a higher relative frequency of the species Licania tomentosa with 45.10%, Handroanthus impetiginosus with 26.65% and Pachira aquatica with 7.51% of the individuals. The best allometric relationships based on the sampling sites were between stem diameter and crown area (R² = 0.63 ) and total height and stem height (R² = 0.50). Our results reflect different allometric patterns between the sampled public areas because each of the sites is provided by cultivation of trees of different species, planting ages and management methods, generating different growth models. Our study is unprecedented and configures itself as one of the bases for discussions on the importance of afforestation within the concepts of environmental services provided by urban green areas.
