RESUMO
BACKGROUND: Vaginal dryness (VD) represents a significant concern affecting women across diverse life stages, encompassing both pre- and postmenopausal women at any age. Dyspareunia, defined by genital pain that can be experienced before, during, or after intercourse, is often associated with vaginal dryness. AIM: This study aimed to evaluate the effectiveness and safety of a water-based vaginal lubricant with hyaluronic acid to reduce sexual discomfort associated with vaginal dryness. METHODS: A prospective, multicenter, uncontrolled clinical investigation was conducted over a three-month period in women aged 18 years or older experiencing pain or difficulty during sexual intercourse for whom the use of a vaginal lubricant was recommended. RESULTS: Significant improvements were observed in the FSFI scores, indicating enhanced sexual function (p < .001). Vaginal dryness symptoms, including irritation, dryness, itching, and dyspareunia, significantly decreased after product use (p < .001). CLINICAL IMPLICATIONS: This study contributes to the limited scientific knowledge on the application of lubricants in the context of symptoms associated with VD. STRENGTHS & LIMITATIONS: In addition to the short study period, inherent limitations of the study design, and lack of placebo control, it is pertinent to acknowledge that some of the pros used in this study were not based on validated questionnaires. However, as far as we know, this study is the only one that analyzes well-being and sexual pleasure as results using a lubricant formulated with hyaluronic acid. CONCLUSION: This tested vaginal lubricant with hyaluronic acid has demonstrated efficacy in improving vaginal dryness and female sexual function, particularly in reducing pain and improving lubrication during sexual intercourse, and showed a favorable safety profile, with minimal and transient adverse events.

La ingeniería bioquímica juega un papel importante en el desarrollo tecnológico de los procesos de obtención ya sea de cuerpos fructíferos de setas con potencial medicinal para el consumo directo, o en la fabricación de nutracéuticos y/o suplementos dietarios. Esta investigación implementó una metodología en biorreactor para el cultivo del hongo macromiceto Lentinula edodes, conocido comúnmente como Shiitake, con el objetivo de evaluar el efecto que tienen la velocidad de agitación y el flujo de aire en la producción de biomasa y de metabolitos de mediana y baja polaridad. Se determinó que el rendimiento y la productividad más altos de producción de biomasa se logra a unas condiciones de 80 rpm y 0,50 vvm obteniendo 0,0260 g/g y 0,00433 g/L*h respectivamente. Igualmente, en cuanto a la composición de esta biomasa, se concluyó que se genera un máximo contenido de proteína (33,4% del micelio liofilizado) a unas condiciones de 140 rpm y 0,75 vvm, los esteroles alcanzaron un porcentaje de 89,32% del extracto en DCM a 80 rpm y 0,5 vvm. Los resultados del análisis por GC-MS confirman la amplia variedad de compuestos que se pueden obtener a partir de un cultivo en biorreactor del hongo Lentinula edodes.
Biochemical engineering plays an important role in the technological development of the processes for obtaining either mushroom fruiting bodies with medicinal potential for direct consumption, or in the manufacture of nutraceuticals and/or dietary supplements. This research implemented a methodology in a bioreactor for the cultivation of the Lentinula edodes macromycete fungus, commonly known as Shiitake, with the aim of evaluating the effect of agitation speed and air flow on the production of biomass and metabolites of median and low polarity. Thus, it was found that the highest yield and productivity of biomass production is achieved at conditions of 80 rpm and 0,50 vvm, obtaining 0,0260 g/g and 0,00433 g/L*h respectively. Likewise, in the study of the content of metabolites it was concluded that for the protein 33,4% of the lyophilized mycelium was reached at conditions of 140 rpm and 0,75 vvm, the sterols reached a percentage of 89,32% of the extract. in DCM at 80 rpm and 0,5 vvm. The results of the GC-MS analysis confirm the wide variety of compounds that can be obtained from a bioreactor culture of the Lentinula edodes fungus.
