Omega-3 is a polyunsaturated fatty acid (PUFA) with a double bond present at the ω-3 carbon atom. Recently, many neurobiologists and psychiatrists have been studying the involvement of inflammatory factors and mechanisms in the pathogenesis of depression, including factors like an improper diet with an excess of omega-6, gut dysbiosis, obesity, and autoimmune diseases. The present study focuses on the impact of unsaturated fatty acids on mood improvement and cognitive processes in elderly patients with major depressive disorder (MDD) resistant to standard treatment. This form of depression is often associated with autoimmune diseases, including rheumatoid arthritis (RA), systemic lupus erythematosus, and inflammatory bowel diseases. The influence of omega-3 supplementation on depression prevention and its effects on childhood depression were also examined. It should be noted that some publications do not confirm the antidepressant effects of omega-3. However, this article provides evidence of the supportive role of omega-3 in depression treatment, based on neuroendocrine, metabolic, and immunological reactions. Objective: Literature review on the impact of omega-3 on depression treatment, considering its forms, inflammatory mechanisms, neuroendocrine factors, diet, lifestyle, and age. Materials and Methods: Literature review based on available sources from PubMed and Google Scholar. Conclusions: Omega-3 is a polyunsaturated fatty acid that positively affects the functioning of the body. Many research studies confirm its antidepressant and anti-inflammatory effects, making it a potential adjunctive treatment for depression, especially in elderly patients with major treatment-resistant depression (MDD) coexisting with other chronic diseases. The results of studies on the relationship between omega-3 and antidepressant action also depend on various environmental factors and lifestyle choices.

Gastric lymphoma is a rare malignant disease, which in recent years has been showing an increasing incidence in the population. The development of MALT is most often the result of chronic Helicobacter pylori infection. Further chronic inflammation may result in malignant transformation of MALT to high-grade diffuse large B-cell lymphoma (DLBCL). However, DLBCL lymphomas most often arise de novo. The risk of primary gastric lymphoma increases with age. The symptoms of gastric lymphoma are very diverse and non-specific, which is why the knowledge about this disease and the differential diagnosis of diseases with similar symptoms play a very important role. The gold standard for diagnosing gastric lymphomas is upper GI endoscopy with biopsy, and sometimes additional imaging tests are necessary to make a proper diagnosis. It is very important to start treatment quickly - the first-line treatment is the eradication of Helicobacter pylori bacteria. Currently, we also have other therapeutic pathways that can change the course of the disease. The therapeutic plan should be individually selected for the needs of the individual patient. Changes detected in the early stages and treated quickly give patients a good chance of being cured. This publication is an attempt to summarize the current state of knowledge about the epidemiology, etiopathogenesis, clinical picture and therapeutic strategies in the case of gastric lymphoma.

The aim of our study is to present a case report of a young patient with rapidly progressive behavioral changes. A 39-year-old well functioning man in a short period of time began to show symptoms like agressive towards his family members, binge eating, apathy, difficulties with social interactions, reduced verbal fluency and poverty of speech, disorders in executive functions and restlessness and anxiety. This behavioral changes appeared in a short period of time (6 months). The concerned family, alarmed by this unusual behavior not previously observed, sought medical help. The patient was disoriented, not receptive to arguments about his atypical behavior, and unaware of the existing problem. A comprehensive diagnostic evaluation (including laboratory, imaging, and neuropsychological assessments) was conducted during the hospital stay. MRI scan showed substantial cortical atrophy in frontal and temporal lobes. Based on the clinical status, typical MRI and neuropsychological examination, the patient was diagnosed with frontotemporal dementia (FTD). The patient received a diagnosis in a very short period of time, which is not typical in establishing a diagnosis for this particular medical condition. The symptoms are often nonspecific, which delays the diagnosis or leads to an incorrect preliminary diagnosis of another medical condition. Difficulties in diagnosing also arise from the non-specific symptoms, which are often overlooked by the patient themselves. It is important to emphasize the crucial role of family members and close associates in recognizing the initial symptoms and making attempts to diagnose the disease. It is also important to provide support and care for the patient's family, for whom the diagnosis of FTD becomes challenging and burdening.

Introduction Breasts are organs found in both male and female representatives. The main building blocks of the breast are fatty tissue and glandular tissue. As far as women are concerned, breast cancer is most commonly found in the upper outer quadrant. It is one of the most common cancers among women worldwide and is therefore an important public health issue. The latest data indicate that the problem of breast cancer currently affects more than 10% of women from all over the world. Importantly, it is the second most common cause of cancer-related death among women, after lung cancer. There are many factors that influence the prevalence rate of breast cancer. In general, they might be divided into modifiable and non-modifiable factors. In the following review, the emphasis will be put on the impact of non-modifiable factors on breast cancer risk and the strength of their impact. Factors that will be discussed include age, gender, ethnic and racial background, family history and genetic factors, pregnancy and breastfeeding. Material and Methods This review was based on available data collected in the PubMed and Google Scholar database, using following keywords: “Breast Cancer”, “Risk factors of Breast Cancer” and “Epidemiology of Breast Cancer”. Conclusion Breast cancer is one of the most common cancers in women worldwide. In recent years, we have observed an increase in the incidence of this cancer among female representatives. The development of this cancer is influenced by many factors, which can be divided into two main groups: modifiable factors and non-modifiable factors. Importantly, it is advisable to undertake new research and initiatives to better understand the etiology of this disease and the factors affecting its development.

Retinoids are a group of substances that include vitamin A and its natural and synthetic derivatives. They are used in the treatment of various skin diseases, such as: rosacea, acne vulgaris, psoriasis. In addition, recently there is a lot of information about the action of preventing photoaging. Oral retinoids have been proven to be the most effective treatment for acne of various severity available today. Through their comprehensive action, affecting the four main factors associated with the pathogenesis of acne, they significantly reduce skin changes. Externally applied retinoids regulate the renewal of epidermal cells, stimulate the production of collagen fibers, increase the production of elastin, and lead to an increase in the number and activity of fibroblasts. Therefore, more and more people are using preparations containing retinoids to prevent skin aging. It has been proven that this procedure leads to shallower wrinkles and slows down the appearance of new ones, and evens out the skin tone. Retinoids are effective substances, but their use is associated with the risk of various side effects, the most common of which are: skin irritation, photosensitisation, headaches, muscle and joint pain, and teratogenicity.

Collagen is a protein and one of the main building blocks of our skin. It is found in bones, tendons, ligaments, internal organs, blood vessels, and the lining of the intestines. In our body, collagen enables the cohesion of tissues and organs, affects hydration, resistance and elasticity of the skin, reduces the risk of developing degenerative joint diseases. Its production decreases with age. As a result, more and more people are taking collagen supplements. It has been proven that doing so can bring many benefits to the body. Taking collagen orally can be an effective way to improve the quality of the skin, increase hydration and delay the aging process. Collagen peptides are potential therapeutic agents for treating osteoarthritis and maintaining joint health. Collagen supplementation may be an element of preventive medicine in the field of cardiovascular diseases. as it significantly reduces fat mass and increases lean mass, it also leads to lower LDL concentrations. A beneficial effect was also noted on hair and nails, as well as on brain function.

Introduction: The COVID-19 pandemic has caused numerous changes to the healthcare system, including care for the newborns. Aim of the study: The aim of the study was to create a clear set of recommendations used in the care of a newborn during the SARS-CoV-2 pandemic. State of knowledge: Despite the low risk of infection of the newborn in utero or during vaginal delivery, in rare cases there is a possibility of vertical transmission of the SARS-CoV-2 virus. Every newborn baby whose mother has been diagnosed with COVID-19 disease should be screened for infection. Suspected neonates should be isolated from healthy children and kept in quarantine until the test result is obtained. It is essential to constantly monitor your baby's health and be alert to any possible signs of infection. Medical personnel should ensure adequate protection when handling an infected newborn. A healthy infant whose mother is SARS-Cov-2 positive may be discharged home provided it is looked after by a healthy caregiver. Summary: New patterns of management in maternity and neonatal departments are associated with changes that may have a significant impact on the mother-child relationship. When making decisions aimed at reducing the spread of SARS-CoV-2 infection, it is necessary to seek solutions taking into account the needs of this particular group of patients.

Introduction: The COVID-19 pandemic significantly changed the lifestyle of pregnant women. Pregnant women with COVID-19 are more likely to suffer from severe disease, as well as unfavorable pregnancy and childbirth. Currently, there is no causal treatment for this disease available, so attention should be paid to preventing infection with vaccines. Aim of the study: A review of the literature on the influence of COVID-19 vaccines on the course of pregnancy and summary of recommendations regarding the use of COVID-19 vaccines during pregnancy and breastfeeding. State of knwoledge: Three types of COVID-19 vaccines are most commonly used: mRNA vaccines, vector vaccines as well as subunit vaccines. In preclinical developmental and reproductive toxicity studies in animal models, there were no alarming safety signals, and observations of vaccinated pregnant women did not reveal any complications with respect to the course of pregnancy and development of the fetus. No cases of neonatal death have been reported in the first 28 days after birth. Most of the side effects following vaccination, such as injection site pain or tenderness, fatigue, fever or muscle pain, were moderate and resolved within 24 hours. The current research results confirm a positive immune response in pregnant women. Moreover, it is important that the presence of antibodies in the umbilical cord blood makes it possible to protect and reduce the risk of SARS-CoV-2 infection of the newborn. Summary: All pregnant women, irrespective of trimester, and breastfeeding mothers are advised to administer a booster dose of the COVID-19 vaccine within an appropriate period of time after the primary vaccination schedule.

Introduction: COVID-19 is an infection caused by the new SARS-CoV-2 virus. In pregnant women with COVID-19, compared to non-pregnant women, there is an increased risk of a severe course of the infection. Pregnant women are more often hospitalized in the Intensive Care Unit and require mechanical ventilation. In the course of COVID-19 infection, pregnant women have a greater risk of miscarriage, premature birth or having a baby with low birth weight, compared to their healthy pregnancy peers. The aim of the study: To present, based on the available literature, the principles of management of a pregnant woman infected with SARS-CoV-2 virus. State of knowledge: The evidence of infection is the detection of the virus in the clinical specimen confirmed by PCR. Chest computer tomography can be useful in diagnosis, especially when the PCR test result is negative. Particular attention should be paid to pharmacological treatment, which should be both effective and safe for the fetus. Certain antiviral and anti-inflammatory drugs as well as anticoagulants drugs are used in COVID-19 therapy. Oxygen and fluid therapy is also important. The condition of the fetus should be monitored regularly. It is recommended to measure the fetal heart rate, perform cardiotocography, pregnancy ultrasound and assess the volume of amniotic fluid. The decision about the time and method of delivery should be made individually on the basis of obstetric indications and the maternal-fetal condition. Summary: The therapy of a pregnant patient infected with SARS-CoV-2 should be adjusted individually depending on the woman's health condition. In therapeutic interventions, the welfare of both the mother and the fetus should be taken into account.
