El Efecto de Cannabis sativa en el cuidado de la piel: una revisión sistemática
(Universidad Santiago de Cali, 2026-05-08) Pérez Galindo, Dahiana Fernanda
Topical products based on phytochemical compounds from Cannabis Sativa (hemp or marijuana) represent a promising alternative for the skincare industry. This plant has been the subject of historical study and is valued in traditional, ancestral, homeopathic, and allopathic medicine due to its complex chemical composition. Among its components, delta-9-tetrahydrocannabinol (THC) stands out, with psychoactive properties and concentrations ranging from 0.5% to 5% in flowers and leaves, as well as other cannabinoids with high industrial potential: cannabidiol (CBD), cannabidolic acid, cannabicidol, and cannabigerol (CBG). Phytochemical analysis has identified more than 60 cannabinoids and 200 additional compounds, opening up a wide range of opportunities for innovation in various production sectors. In this context, this review article aims to identify the scientific evidence on the use of phytocannabinoids in the development of specific products, such as emulsions and creams for dermal application. The results of the systematic review indicate that scientific production on research into the use of Cannabis Sativa has grown steadily, reaching its peak in 2021. The sustainable geographic scope, predominantly from Colombia, Spain, and the United States, also incorporates perspectives from more than 20 countries, supported by bibliographic references from original articles, specialized journals, legal regulations, and grey literature. The research period covers the years 2013 to 2023. Finally, the research was characterized as a multidisciplinary and international study, with strong support from databases such as ScienceDirect and PubMed, among others.

ABSTRACT: Microbiological control is a necessary component of any veterinary practice to protect the safety of personnel and animals and to minimize the risk of nosocomial infections. The purpose of this study is to evaluate the effectiveness of ultraviolet C (UV-C) light as a means of disinfecting hospital cages in a veterinary clinic in Cali, in contrast to the traditional method of using sodium hypochlorite. A longitudinal experimental design was used, and sampling was carried out with swabs that were analyzed in a laboratory by culturing the swabs on nutrient agar followed by incubation for 24-48 hours at 37 degrees Celsius to qualitatively determine whether there was bacterial growth or not. The results indicated that the control samples had bacterial growth; there was a partial reduction in bacterial growth with the use of sodium hypochlorite; and there was a relationship dependent on the exposure time to UV-C, which resulted in the total elimination of microbial growth after 10 minutes. The results of this study contributed to the knowledge that UV-C light is a highly effective means of disinfecting veterinary hospitalization cages and that there are operational and environmental benefits to using UV-C light disinfection instead of traditional chemical disinfection methods, and, therefore, it would be a good addition to the biosecurity measures used in veterinary hospitals.
Efecto del cambio de temperatura ambiental en la dinámica poblacional de Aedes aegypti y en la transmisión de enfermedades zoonóticas en la zona amazónica de Brasil. Revisión sistemática
(Universidad Santiago de Cali, 2026-06-24) Calceto Valencia, Gabriel; Guarin Patarroyo, Camilo(Director)
Introduction: Climate change, characterized by rising global temperatures, poses significant challenges to public health, particularly in ecologically sensitive regions such as the Brazilian Amazon.
Methods: A systematic literature search was conducted using the selected databases, following PRISMA guidelines. Experimental, epidemiological, and modeling studies were included if they analyzed the relationship between temperature and biological parameters of the vector (reproduction rates, development, survival) and/or the incidence of arboviruses (dengue, Zika, chikungunya) in the Brazilian Amazon region or under relevant experimental conditions. Opinion articles, non-systematic reviews, and studies focused exclusively on other regions without relevant data for the Amazon were excluded.
Results: A total of 28 studies were included in the qualitative synthesis. The evidence consistently demonstrates that temperature is a key determinant in the biology of Aedes aegypti. Increasing temperature significantly accelerates larval development, shortens the life cycle, and increases female fecundity, leading to higher vector population density. However, extreme temperatures (>32–35°C) may have deleterious effects, increasing mortality and reducing survival. Likewise, modeling studies project an expansion of climatically suitable areas for Aedes aegypti in southern Brazil, while in warmer regions such as the Amazon, extreme temperature increases could paradoxically render some areas thermally limiting during certain times of the year.
Conclusions: The reviewed evidence confirms that environmental temperature change is a key driver of Aedes aegypti population dynamics in the Brazilian Amazon. Warmer temperatures, within certain limits, accelerate its life cycle and enhance its vectorial capacity, increasing the risk of arbovirus transmission. Climate projections indicate a complex scenario in which some areas may become higher-risk zones, while others may experience seasonal reductions in transmission potential due to extreme heat. These findings underscore the urgent need to integrate climate, entomological, and epidemiological surveillance to develop early warning systems and adaptive, region-specific control strategies for the Amazon
Caracterización de la resistencia antimicrobiana de bacterias aisladas del arrecife La Azufrada del Parque Nacional Natural Isla Gorgona
(Universidad Santiago de Cali, 2026-06-22) Garcia Torres, Luisa Maria; Ocampo Ibáñez, Iván Darío(Director)
This research addresses the issue of antimicrobial resistance and the health status of the marine
ecosystem in relation to the presence of resistant and multidrug-resistant bacteria. The main objective
was to evaluate the antimicrobial activity of bacteria isolated from the La Azufrada reef, located in the
Gorgona Island National Natural Park. For this purpose, the Kirby-Bauer disk diffusion susceptibility
test methodology was employed. The results revealed the presence of resistant and multidrug-
resistant bacteria, which are of interest to public health. It is concluded that the health of the marine
ecosystem is being affected by various anthropogenic wastes, and that the bacteria found constitute
a relevant indicator of the deterioration of the aquatic and marine ecosystem.
Caracterización microbiana del compost elaborado con fibra de caña de azúcar como estrategia sostenible para el aprovechamiento de residuos agroindustriales: Una revisión sistemática.
(Universidad Santiago de Cali, 2026-06-24) Grueso,Rulaes, Diego fernando.; Restrepo,Garcia,yessenia .; Alexis Gafaro Montejo (Director)
The sugarcane agroindustry in Colombia generates large amounts of by-products such as fiber, bagasse, and filter cake. Although these residues have high agricultural potential, they are often improperly managed, causing environmental impacts and leading to the loss of valuable nutrients. Composting emerges as a sustainable alternative to transform these lignocellulosic residues into organic amendments, where microbial activity plays a key role in determining process efficiency, maturity, and compost quality. This study aimed to identify the main microorganisms present in compost produced from sugarcane fiber through a systematic review of scientific literature published between 2014 and 2024. The search was conducted in databases such as Scopus, ScienceDirect, Redalyc, and Scielo, following PRISMA guidelines. From an initial set of 351 documents, 31 studies met the established inclusion and exclusion criteria and were analyzed in detail. Results indicate the predominant presence of aerobic heterotrophic bacteria, filamentous fungi of the genus Aspergillus, and actinobacteria capable of degrading cellulose and lignin, thus enhancing compost stability and maturity. Some studies also highlight the use of bioinoculants and molecular tools to optimize microbial activity, accelerate decomposition, and improve the final product’s quality. In conclusion, available information on microbial characterization of compost from sugarcane fiber remains fragmented, limiting the development of technical protocols applicable at a local scale. This review provides a scientific basis for future research and for implementing sustainable waste management strategies in the sugarcane sector.
