The exponential growth of human interactions on social media via the internet has revolutionized global communication, but it has also emerged as a critical factor in mental health linked to suicidal ideation and mental disorders. This systematic review and meta-analysis aimed to synthesize evidence on the most prevalent disorders in adolescents and young adults associated with social media use based on previous research, highlighting risk factors and key findings. Publications from 2020 to 2024 in highly relevant databases were reviewed following the PRISMA declaration guidelines. The meta-analysis (conducted in R software) of the included documents (24 studies, 68 effects) verified a significant and positive association between exposure to risk factors in social networks and various disorders in adolescents and young adults (aggregate correlation r = 0.2173, 95% CI [0.1826, 0.2520], p ≤ 0.0001), although with high heterogeneity (I2 = 99.66%). Prevention strategies were indicated by revealing data from contexts in which 40% of adolescents who died by suicide had developed online identities focused on suicidal thoughts.

Background: The leafcutter ant (Atta cephalotes) is associated with losses in the agricultural sector, due to its defoliating activity; for its control, biological, mechanical and chemical methods have been developed, the latter associated with adverse effects on human and environmental health. This research validated in the field for the control of the leafcutter ant (A. cephalotes) using a mixture of Beauveria bassiana and Trichoderma lignorum spores. Methods: The effectiveness from the combination of spores of B. bassiana and T. lignorum with an initial concentration of 2 × 109 spores/ml, in the following proportions of B. bassiana and T. lignorum, A (1:1), of each fungus. It was evaluated within the university campus, comparing it with two commercial formulations, Mycotrol (B. bassiana) and Mycobac (T. lignorum). Additionally, this formulation was evaluated in 49 nests distributed 16 in 14 locations in Colombia. The formulation application was carried out by direct application, using a pump at a speed of 10 ml/m2. The effectiveness was estimated from the reduction of the flow of ants, evaluating the statistically significant differences using the ANOVA and Tukey-test. Results: Effective control of 90% of the nests was observed in the field phase in 60 days, except in nests with areas > 50 m2 that were located in regions with high rainfall (annual average precipitation above 7000 mm), such as Buenaventura. Conclusions: In this work, it was demonstrated that the combination of B. bassiana and T. lignorum spores represent a viable alternative for the control of the leafcutter ant, in which the effectiveness is related to several factors, including the size of the nest and the rainfall in the area.

Fermentation is an ancient process used to prepare and preserve food. Currently, fermented beverages are part of the culture of people living in the Colombian Andean Region, and they are a vital part of their cosmology and ancestral vision. Chicha, Forcha, Champús, and Masato are some of the most common Colombian Andes region’s traditional fermented beverages. These drinks come from the fermentation of maize (Zea maize), but other cereals such as wheat or rye, could be used. The fermentation is carried out by a set of bacteria and yeasts that provide characteristic organoleptic properties of each beverage. In this work, the information collected from the metagenomics analyses by sequencing ITS 1-4 (Internal Transcriber Spacer) and the 16S ribosomal gene for fungi and the V3-V4 region of the rDNA for bacteria allowed us to identify the diversity present in these autochthonous fermented beverages made with maize. The sequencing analysis showed the presence of 39 bacterial and 20 fungal genera. In addition, we determined that only nine genera of bacteria and two genera of fungi affect the organoleptic properties of smell, colour, and flavour, given the production of compounds such as lactic acid, alcohol, and phenols, highlighting the critical role of these microorganisms. Our findings provide new insights into the core microbiota of these beverages, represented by Lactobacillus fermentum, Acetobacter pasteurianus, and Saccharomyces cerevisiae.

Introducción: Poco se sabe acerca de la presencia del VPH en la mucosa oral en población sana y cuales son los factores de riesgo que pueden llevar al virus a una infección persistente que conduzca al desarrollo de un carcinoma.Objetivos: en el presente estudio la detección del VPH se realizó en muestras de ADN obtenidas de la mucosa oral de 76 mujeres sanas.Métodos: el VPH se detectó mediante la técnica de PCR anidada para el gen viral L1. La genotipificación se realizó mediante la secuenciación directa del fragmento del gen L1 amplificado por el método de Sanger, seguido de un análisis de porcentajes de identidad.Resultados: el porcentaje de detección de VPH fue de 6.6 por ciento. Los genotipos virales identificados fueron HPV-11, HPV-43 y HPV-72, todos clasificados de bajo riesgo oncológico. Además, se observó que el no uso del condón en este grupo de edad se asoció significativamente con la presencia de VPH en la mucosa oral (p = 0.037).Conclusión: en la presente investigación exploratoria se evidencio una mayor detección de VPH en la mucosa oral de mujeres sanas y su presencia se asocia con una vida sexual activa sin una protección adecuada contra su transmisión.

Colombian palm wine is a traditional fermented beverage produced from the sap of Attalea butyracea, whose microbiota and biochemical features remain poorly characterized. A comprehensive analytical framework was applied to palm wine samples from three Andean producers. This included the determination of proximate composition, total phenolic content, and antioxidant activity, alongside a dual microbiological approach: traditional plate counting and high-throughput 16S rRNA/ITS metabarcoding. PICRUSt2 was employed to predict KEGG-based metabolic pathways to elucidate the microbial functional potential. The wines exhibited a low pH (3.35–3.65), a variable ethanol content (1.62–8.40 g/L), high residual sugars, moderate microbial loads, and limited antioxidant activity (as measured using the ABTS and DPPH assays). Analysis using high-throughput sequencing revealed high bacterial community diversity, dominated by Liquorilactobacillus nagelii, Limosilactobacillus fermentum, Limosilactobacillus panis, Lacticaseibacillus casei, and Zymomonas mobilis alongside the yeast Saccharomyces cerevisiae. Functional profiling revealed a significant enrichment in metabolic pathways related to carbohydrates, amino acids, and cofactors/vitamins, as well as xenobiotic biodegradation and metabolism. These findings provide the first integrated microbiological and physicochemical characterization of Colombian palm wine and highlight its biotechnological potential.
