Background: In 2020, the World Health Organization (WHO) estimated that 650 million adults worldwide are obese, and 2.8 billion individuals struggle with overweight. Obesity is associated with an increased risk of cardiovascular diseases, type 2 diabetes, heart disease, adverse effects on mental health, the development of certain cancers, and other conditions. In recent years, there has been growing interest in the role of melatonin, which has therapeutic potential in the treatment of obesity. Studies suggest that melatonin supplementation may lead to weight reduction and improvement in metabolic parameters, significantly reduce cardiovascular disease risk factors, and enhance insulin sensitivity in obese individuals. Aim of study: This review aims to present the latest scientific findings on the impact of melatonin supplementation on the development of obesity and its complications. We focus primarily on the mechanisms of melatonin's action in the context of obesity, particularly on potential pathways that have not yet been thoroughly explored. Our aim is to provide deeper insights into research on obesity and its prevention. Materials and Methods: Search was conducted using PubMed and Google Scholar databases, utilizing the keywords "obesity," "melatonin," and "weight loss" in various configurations. The review primarily considers studies published after 2016 that are available online. Summary Melatonin supplementation leads to a statistically significant reduction in blood glucose levels and an increase in cellular insulin sensitivity. Its promising properties in the treatment of obesity have been demonstrated through the reduction of oxidative stress, indicating a potential adjunct for weight loss. Based on the cited studies, the beneficial effects of melatonin supplementation on cardiovascular risk factors have been confirmed. Melatonin could be considered as an adjunctive therapy for obese individuals who do not respond to other treatment modalities.

INTRODUCTION AND PURPOSE: Long non-coding RNAs are key regulators of gene expression and tumorigenesis. Deleted in leukemia 1 (DLEU1) is significant in cancer development. This article reviews DLEU1's role across cancers, assessing its diagnostic and therapeutic potential. METHODS: A review of scientific articles from PubMed and Google Scholar was conducted. DESCRIPTION OF THE STATE OF KNOWLEDGE: DLEU1 drives tumor growth in glioblastoma, esophageal, colorectal, and oral cancers by interacting with key miRNAs and genes, promoting malignancy. In breast and ovarian cancers, DLEU1 modulates migration and invasion via specific pathways. In cervical cancer, DLEU1 is linked to immune modulation and serves as a prognostic marker. SUMMARY: DLEU1 is a vital regulator in various cancers, offering potential as a diagnostic and therapeutic target.

Introduction: Cytomegalovirus (CMV) is a double-strand DNA virus, member of the viral family known as Herpesviridae which is wide-spread. CMV infection is the most common congenital infection worldwide. Disease is mostly asymptomatic for healthy people, therefore is detected late, when the children start presenting symptoms. Unfortunately the congenital CMV infection leads to the serious health problems for infants. Detection of the virus is typically done through quantitative PCR assays. Infection especially affects nervous system and can present infant’s deafness. Earlier it was equivalent with the children being deaf till the end of life, but nowadays thanks to the development of laryngological methods (ex. cochlear implantation) patients have chance to grow up correctly. Material and methods: A literature search was conducted using Google Scholar, PubMed, and Web of Science databases. We searched articles by entering key words in the appropriate configuration: “CMV”, “Congenital CMV infection”, “valganciclovir”, “infant’s deafness”. Scientific articles published between 1991–2023 were analyzed from all over the world and guidelines of Polish Society of Epidemiology and Infectious Diseases. Conclusions: Currently we haven’t got prevention towards congenital CMV, only the treatment for infants: valganciclovir. It stops development of severe symptoms. There are available analysis, where using valganciclovir during pregnancy reduces the possibility or soften the course of the congenital CMV infection , but it’s not the obligatory guidelines. In many countries researchers want to conduct screening test for CMV IgG among the pregnant women.

Introduction and purpose Infective endocarditis (IE) is a disease resulting from infection of the endocardium. In addition to cardiac symptoms, frequent complications of IE include various damage to the nervous system. The aim of this study is to describe the current state of knowledge about the neurological complications of infective endocarditis. Methods Medical publications were reviewed using the "PubMed" and "Google Scholar" databases. The obtained results were verified in terms of the following criteria: publication in 2016, retrospective analysis, obtaining 44 papaers covering a total of 8067 patients. The information was supplemented with case reports and meta-analyses. Description of the state of knowledge Neurologic complications occur in 20 to 60% of patients with IE. The most common is ischemic stroke, the symptoms of which may precede the diagnosis of IE. Less common complications that often remain asymptomatic include mycotic aneurysms and intracranial hemorrhages. Infectious material entering the brain may also cause meningitis and brain abscess. However, these complications do not occur often. Magnetic resonance imaging of the head is an effective test for detecting neurological damage in the course of IE. The recommendation for routine use of this test is debatable. In addition to antibiotic therapy, cardiac surgery is used to treat IE to remove bacterial vegetation. Research indicates the high effectiveness of this type of surgery in the prevention and treatment of neurological complications of infective endocarditis.

Background: Kallmann syndrome is a rare congenital disorder characterized by hypogonadotropic hypogonadism and anosmia or hyposmia. KS results from abnormalities in the migration of GnRH neurons from the nasal placode to the hypothalamus. The prevalence of KS is estimated to be approximately 1:30,000 in males and 1:125,000 in females. KS manifests at various stages of life, ranging from the neonatal period through adolescence to adulthood. In the neonatal period, boys may present with cryptorchidism and micropenis, while symptoms in girls may be less apparent. During adolescence, patients often experience the absence or incomplete development of secondary sexual characteristics. In adulthood, KS often leads to infertility, cardiovascular issues, and neurological symptoms. Diagnostic methods include olfactory tests and hormonal analysis, assessing levels of gonadotropins, testosterone, LH and FSH. MRI can reveal structural abnormalities in the olfactory system. Aim of study: The goal of this article was to gather information about the Kallmann syndrome, focusing on its epidemiology, etiology, characteristic features, and treatment strategies. Materials and Methods: A review of the literature available in the “PubMed”, Google Scholar and Medline databases. The search was performed by using following keywords: “kallmann syndrome”, “anosmia”, hypogonadotropic hypogonadism”. Results and conclusions: Kallmann syndrome is a complex condition that necessitates a multifaceted approach to diagnosis and treatment. Early identification of the disorder is crucial, allowing for the timely initiation of appropriate hormonal therapy and psychological support, which significantly improves the quality of life for patients. Further research into the genetic and neurobiological mechanisms of KS is essential for the development of more effective therapeutic and diagnostic methods.

Results and conclusions: In spite of the progress of science the preeclampsia is still a serious threat for pregnant women all around the world. Thank to the advanced molecular and ultrasonographic techniques the doctors can estimate the risk of complications. The most important is screening, which helps the doctors to define the group of risk and then launch the treatment. That should decrease the amount of maternal and neonatal complications and deaths.

Colchicine, a lipid-soluble alkaloid derived from Colchicum autumnale, has a long history of use dating back to ancient Egypt. Traditionally used to alleviate pain and swelling, colchicine is now administered for various diseases, including gout and Familial Mediterranean Fever (FMF). Recent studies have expanded its applications to atherosclerotic cardiovascular diseases, such as acute coronary syndromes and COVID-19. This review aims to summarize the diverse clinical applications of colchicine, with a particular focus on its role in athletes and the synergistic effects of physical exercise in these conditions. Colchicine exhibits broad anti-inflammatory effects primarily by disrupting microtubule functions, which impairs neutrophil migration and reduces cytokine production. Despite its narrow therapeutic window and potential for drug interactions, colchicine is considered safe and effective for managing conditions like gout, FMF, and acute coronary syndromes. Physical exercise complements colchicine treatment by enhancing symptom control and disease management. However, the role of colchicine in COVID-19 treatment remains inconclusive, necessitating further research.

Introduction: Psoriasis is a systemic inflammatory disease with an immunological basis. The estimated number of people suffering from psoriasis is 60 million. Despite the large number of patients with this diagnosis, the question of which mechanisms are mainly responsible for its development has not yet been answered. One theory is that a change in the patient's psychological state acts as a trigger for the manifestation and worsening of the disease. Another unresolved issue is the relationship between sports and psoriasis. While some studies suggest exercise might worsen symptoms, others highlight potential benefits like improved quality of life. Aim of the study : The aim of our study is to present connection between mental state of patients and occurance of psoriasis. Additionally, the study aims to elucidate the potential benefits of integrating psychological interventions and physical activity into psoriasis management strategies, with the goal of improving patient outcomes and enhancing overall quality of life. Material and methods : We searched electronic databases, using keywords such as „Psoriasis”, „Depression” and „Psoriasis and sport ”. Conclusions : Psoriasis stands as a profound example of the intricate interplay between physical health and mental well-being. The findings presented in this paper underscore the importance of a holistic approach to psoriasis management, integrating dermatological, psychological, and physical interventions.

Introduction: Depression is the most common mental disorder, affecting a significant percentage of the adult population. The disease is associated with many negative health consequences and is one of the leading causes of disability and inability to work worldwide. This neurological condition is commonly associated with neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD) and Huntington's disease (HD). In recent decades, advancements have uncovered certain pathophysiological and molecular mechanisms underlying these disorders. These revelations suggest that, although they exhibit unique characteristics, there are notable parallels in the neurobiological changes associated with major depressive disorder (MDD) and the neurodegenerative processes in Alzheimer's disease, Parkinson's disease, and Huntington's disease. In this article the relevance of non-pharmacological therapies in the management of neurodegenerative diseases have been rising. Almost absent from side effects, non-pharmacological alternatives, including physical exercise have shown promising benefits. Aim of the study: The study aims to evaluate the association between depression symptoms and neurodegenerative diseases. Moreover, we indicate sport as a way to preserve and improve cognitive function, and to maintain a proper quality of life. Material and methods: We conducted a review of scientific publications published in the years 1998-2024 in English and Polish in the PubMed and Google Scholar databases. We used keywords such as "depression", "neurodegeneration” and “physical exercise”. Conclusions: Depression has been demonstrated to be a risk factor for neurodegenerative diseases and suggested to be a possible prodrome for them. However, sport can alleviate behavioral symptoms in neurodevelopmental disorders, like anxiety, depression, indifference and sleep disruptions.
