Sudden infant death syndrome (SIDS) is a complex, multifactorial phenomenon with an etiology that has not been fully clarified to this day. Despite a noticeable decrease in the number of SIDS cases worldwide, sudden infant death syndrome remains one of the most common causes of death among children in infancy. Sudden infant death syndrome is still the subject of scientific research aimed to clearly determine and identify potential pathogenetic factors responsible for the occurrence of SIDS. Many years of efforts to clarify the etiology of the discussed issue have made it possible to characterize important factors that increase the risk of sudden infant death syndrome. In addition, research has made it possible to develop important approaches that make a significant contribution to reduce the risk of SIDS in an infant. Complete knowledge of the specific conditions that have a protective effect against SIDS will significantly reduce the risk of sudden infant death syndrome, so a very important aspect is not only their precise analysis, but also their propagation among the public.

Background: Transcranial magnetic stimulation (TMS) is a method of non-invasive and painless brain stimulation with an electromagnetic field, which induces changes in the electric field in the brain leading to the cortical activity modulation and stimulation of neurons. Currently, transcranial magnetic stimulation is increasingly used in the diagnosis and treatment of various neuropsychiatric conditions, such as depression, schizophrenia, neurodegenerative diseases, and more. TMS can be used as a method of enhancing the effect of pharmacotherapy as well as a regular treatment. Aim of the study: The study's aim is to summarize the current state of knowledge on transcranial magnetic stimulation as a method of treatment in depression and various neuropsychiatric conditions. Material and methods: The study is based on the literature available in scientific databases such as PubMed, using the following keywords: „transcranial magnetic stimulation”, „tms”, “depression” and “treatment-resistant depression”. Results and conclusions: Transcranial magnetic stimulation is a non-invasive, painless and generally safe method of diagnosis and treatment of many neuropsychiatric diseases, such as depression, schizophrenia, obsessive-compulsive disorders, neurodegenerative diseases, tinnitus, addiction to psychoactive substances and many more. TMS is a well-documented, approved, and recommended treatment primarily for treatment-resistant depression due to its effectiveness, mild side effect profile and good tolerability. Recently there are more and more reports on the effectiveness of TMS in the diagnosis and treatment of other neuropsychiatric conditions, but further research and setting guidelines are needed, so is increasing the availability of the method for patients.

Introduction: Type 1 diabetes is a common and debilitating disease that requires regular glycemic control to prevent potentially fatal hypoglycemia. Objective: The aim of this study is to demonstrate the purpose, process, and consequences of pancreatic islet transplantation in patients with type 1 diabetes. Additionally, the results of the procedure after several years are described based on the available publications. Materials and Methods: The authors created a summary of available publications on pancreatic islet transplantation, based on databases such as PubMed and Google Scholar. Using the terms listed in the "key words" section, the authors searched for relevant information in other scientific papers to create the following review. Conclusions: Reducing the number of donors and developing alternative sources of pancreatic islet cells for transplantation is an active area of research, that promises to expand access and indications for pancreatic islet transplantation in future diabetes treatment.
