Safety of Innovative Nanotechnology Oral Formulations Loaded with Bioactive Menopause Molecules: Influence of Genotoxicity and Biochemical Parameters on a Menopausal Rat Model

Update on Genitourinary Syndrome of Menopause: A Scoping Review of a Tailored Treatment-Based Approach

This scoping review explores the therapeutic strategies available for managing genitourinary syndrome of menopause (GSM), a condition often underdiagnosed and undertreated despite significantly affecting women's quality of life. GSM results from decreased estrogen levels during menopause, leading to a range of symptoms including vulvovaginal atrophy and urinary tract issues.

MATERIAL AND METHODS

we screened the literature for original studies with "menopause", "hormonal therapy", "vulvovaginal atrophy", "urinary incontinence", "urinary infections", "genitourinary syndrome".

RESULTS

A total of 451 relevant articles were retrieved. After screening, 19 articles were included in this scoping review.

DISCUSSION

First-line treatments typically include lubricants and moisturizers for short-term symptom relief, while unresolved or severe cases may warrant hormonal treatment. Topical hormonal treatments often have fewer side effects than systemic alternatives. Special attention is given to selective estrogen receptor modulators like ospemifene and steroid hormones like dehydroepiandrosterone (DHEA), which have shown beneficial effects on GSM symptoms. Moreover, innovative therapeutic approaches, such as laser treatment, are discussed in the context of their efficacy and accessibility. The safety of GSM hormonal therapy in women with a history or risk of cancer is also addressed, noting the need for more definitive research in this area. While there is a growing demand for tailored therapy, this scoping review emphasizes the importance of effective communication and counseling to allow women to make informed decisions about their treatment. Overall, this review underscores the need for increased awareness and further research into effective treatment options for GSM.

Oral nano-formulations for endocrine therapy of endometrioid adenocarcinomas

Endometrial cancer is one of the three major malignant tumors of the reproductive system that threaten women's lives and health. The incidence of this disease is on the rise globally. Most cases of endometrial cancer comprise endometrioid adenocarcinomas, whose treatment is challenged by factors such as their high recurrence rate and the need to preserve fertility among young patients. Thus, oral endocrine therapy has become the main treatment modality. The main drugs used in oral endocrine therapy are progestins, selective estrogen receptor antagonists, and aromatase inhibitors. However, their clinical use is hindered by their low solubility and low oral utilization. The rapid development of nanotechnology allows the combination of these drugs with oral nano-formulations to create a good carrier. Such nanocarriers, including nanospheres, nanocapsules, and micelles can protect the drug against clearance and increase the site specificity of drug delivery. This paper reviews the pathogenesis of endometrioid endometrial cancer (EEC) and oral nano-formulations for endocrine therapy.

Natural-Origin Betaine Surfactants as Promising Components for the Stabilization of Lipid Carriers

In the present work, we demonstrate studies involving the influence of the formulation composition on the physicochemical properties of nanocarriers: solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs). Novel lipid-origin platforms were prepared using two "green" betaine-based surfactants, cocamidopropyl betaine (ROKAmina K30) and coco betaine (ROKAmina K30B), in combination with three different solid lipids, cetyl palmitate (CRODAMOL CP), trimyristin (Dynasan 114), and tristearin (Dynasan 118). Extensive optimization studies included the selection of the most appropriate lipid and surfactant concentration for effective SLN and NLC stabilization. The control parameters involving the hydrodynamic diameters of the obtained nanocarriers along with the size distribution (polydispersity index) were determined by dynamic light scattering (DLS), while shape and morphology were evaluated by atomic force microscopy (AFM) and transmission electron microscopy (TEM). Electrophoretic light scattering (ELS) and turbidimetric method (backscattering profiles) were used to assess colloidal stability. The studied results revealed that both betaine-stabilized SLN and NLC formulations containing CRODAMOL CP as lipid matrix are the most monodisperse and colloidally stable regardless of the other components and their concentrations used, indicating them as the most promising candidates for drug delivery nanosystems with a diverse range of potential uses.
