Supplementation of micronutrients is considered to be crucial in the reinforcement of the skin’s barrier. In this paper, 14 nutritional compounds commonly used in food or pharmaceutic industries were analyzed in terms of influencing skin conditions. The major objective of this paper was to provide a narrative review of the available literature regarding several chosen compounds that are currently widely recommended as supplements that aim to maintain proper and healthy skin conditions. We conducted a review of the literature from PubMed, Scopus, and Web of Science until September 2023 without any other restrictions regarding the year of the publication. Ultimately, we reviewed 238 articles, including them in this review. Each of the reviewed compounds, including vitamin A, vitamin C, vitamin D, vitamin E, curcumin, chlorella, Omega-3, biotin,Ppolypodium leucotomos, Simmondsia chinesis, gamma oryzanol, olive leaf extract, spirulina, and astaxanthin, was observed to present some possible effects with promising benefits for a skin condition, i.e., photoprotective radiation. Adding them to the diet or daily routine might have a positive influence on some skin inflammatory diseases such as atopic dermatitis or psoriasis. Further, UV radiation protection facilitated by some supplements and their impact on human cells might be helpful during chemotherapy or in preventing melanoma development. Further research is needed because of the lack of clear consensus regarding the doses of the described compounds that could provide desirable effects on the skin.

Glaucoma is a leading cause of irreversible blindness and is characterized by increased intraocular pressure (IOP) and progressive optic nerve damage. The current therapeutic approaches for glaucoma management, such as eye drops and oral medications, face challenges including poor bioavailability, low patient compliance, and limited efficacy. In recent years, nanotechnology has emerged as a promising approach to overcome these limitations and revolutionize glaucoma treatment. In this narrative review, we present an overview of the novel nanotechnologies employed in the treatment of primary open-angle glaucoma. Various nanosystems, including liposomes, niosomes, nanoparticles, and other nanostructured carriers, have been developed to enhance the delivery and bioavailability of antiglaucoma drugs. They offer advantages such as a high drug loading capacity, sustained release, improved corneal permeability, and targeted drug delivery to the ocular tissues. The application of nanotechnologies in glaucoma treatment represents a transformative approach that addresses the limitations of conventional therapies. However, further research is needed to optimize the formulations, evaluate long-term safety, and implement these nanotechnologies into clinical practice. With continued advancements in nanotechnology, the future holds great potential for improving the management and outcomes of glaucoma, ultimately preserving vision and improving the lives of millions affected by this debilitating disease.

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection has become a worldwide threat resulting in a pandemic in 2020. SARS-CoV-2 infection manifests itself as coronavirus disease 2019 (COVID-19) that is evidenced in a vast number of either specific or nonspecific symptoms. Except for typical (but nonspecific) symptoms such as fever, dry cough, or muscle weakness, the infected patients might also present atypical symptoms including neurological, dermatological, or ophthalmic manifestations. This paper summarizes the current state of knowledge regarding the onset, progression, and types of ophthalmic symptoms induced by SARS-CoV-2 infection recognized amongst the infected patients.

Endometrial cancer is reported to be one of the most prevalent cancers of the female reproductive organs worldwide, with increasing incidence and mortality rates over the past decade. Early diagnosis is critical for effective treatment. Recently, there has been a growing focus on the role of nutrition and micronutrient and macronutrient status in patients with gynecologic cancers, including endometrial cancer. In the following paper, we have conducted an in-depth narrative literature review with the aim of evaluating the results of metallomic studies specifically concerning the micro- and macronutrient status of patients with endometrial cancer. The main objective of the paper was to analyze the results regarding the nutritional status of endometrial cancer patients and describe the role of chosen elements in the onset and progression of endometrial carcinogenesis. Further, we have focused on the evaluation of the usage of the described elements in the potential treatment of the abovementioned cancer, as well as the possible prevention of cancer considering proper supplementation of chosen elements in healthy individuals. Calcium supplementation has been proposed to reduce the risk of endometrial cancer, although some studies offer conflicting evidence. Deficiencies in phosphorus, selenium, and zinc have been inversely associated with endometrial cancer risk, suggesting they may play a protective role, whereas excessive levels of iron, copper, and cadmium have been positively correlated with increased risk. However, the molecular mechanisms by which these elements affect endometrial carcinogenesis are not fully understood, and current findings are often contradictory. Further research is needed to clarify these relationships and to evaluate the potential of nutritional interventions for the prevention and treatment of endometrial cancer.

Introduction and objective Gel nail allergies have become a growing concern in recent years, as individuals experience adverse immune reactions to the chemicals present in gel nail products. The popularity of gel nails, known for their long-lasting and durable finish compared to traditional nail polishes, has increased in the beauty industry. However, specific constituents, particularly acrylate compounds used in gel nail formulations, can trigger allergic responses in susceptible individuals. Abbreviated description of the state of knowledge Findings from the reviewed articles indicate that allergic reactions to acrylates in gel nail products can manifest in various ways, including contact dermatitis, dermatoses, and general allergic responses. Nail technicians, due to their frequent exposure to gel nail products and other potential allergens, are particularly vulnerable to occupational hazards associated with acrylate sensitization. These insights highlight the need for preventive measures to protect the health and well-being of nail technicians and promote a safer working environment. Summary This literature review addresses the emerging issue of gel nail allergies and provides valuable information regarding the prevalence and characteristics of allergic reactions to acrylates. The article underscores the significance of increasing awareness, implementing preventive measures, and effectively managing gel nail allergies. By doing so, the beauty industry can ensure a safer approach to gel nail applications, benefitting both nail technicians and consumers alike.

Primary dysmenorrhea is the most common, though often underdiagnosed, gynecological disorder of women of reproductive age. The disease presents with painful abdominal cramps associated with menstrual bleeding in the absence of pelvic abnormalities. Symptoms are caused primarily by increased levels of prostaglandins produced by the endometrium, which provides hypercontraction of the uterine muscles, ischemia, and pain. Dysmenorrhea is usually treated pharmacologically with non-steroidal anti-inflammatory drugs or hormonal contraception. In particularly severe cases, surgical treatment is also possible. Nonetheless, an increasing amount of studies on non-pharmacological treatments have been published recently. Methods like Transcutaneous Electrical Nerve Stimulation (TENS), acupuncture, continuous topical heat, or exercise and yoga seem to be effective in reducing the symptoms of primary dysmenorrhea. All have an anti-inflammatory effect by lowering prostaglandin levels, but they also contribute to reducing symptoms through other mechanisms. TENS elevates the pain threshold and, together with acupuncture, causes the release of endogenous opioids. Heat, yoga, and acupuncture also lead to increased blood flow in the uterus, reducing hypoxia. Their additional advantage is the low cost and ease of self-use, except for acupuncture, depending on the patient's needs. Side effects of non-pharmacological treatments are usually mild and rarely reported.
