The HIV (Human Immunodeficiency Virus) epidemic remains a significant public health issue, requiring ongoing access to preventive methods. This study aimed to analyze the evolution of the HIV epidemic in Lower Silesia from 2010 to 2020, focusing on the key populations. A retrospective analysis of the medical records from newly diagnosed HIV patients at a major HIV clinic in Wroclaw was conducted, examining demographic data, infection routes, and laboratory results. An 84% increase in newly diagnosed HIV cases was observed over the decade, with the most common route of infection being sex between men (70% among those with a known infection route). These patients were generally in better clinical condition compared to their heterosexual counterparts, as indicated by a higher median CD4+ T cell count (465/μL vs. 250/μL). The changes in clinical status and infection routes were statistically significant. The HIV epidemic in Lower Silesia has shifted, with a notable rise in new infections among men who have sex with men. Heterosexual patients were often diagnosed at more advanced stages. Prevention strategies should adapt to these changing trends, with education and testing accessibility remaining priorities nationwide.

Introduction: Human Immunodeficiency Virus (HIV) remains a major global health issue. In Poland, men represent 79% of the HIV-infected population, but the proportion of women diagnosed has been increasing. This study examines the clinical condition of newly diagnosed HIV-1 patients in Lower Silesia at three key points: 2010, 2016, and 2020, to understand infection dynamics and improve regional screening and prevention efforts. Objective: The objective of the study is to compare the clinical condition of newly diagnosed women and men with HIV-1 in Lower Silesia at three time points in order to identify trends and differences that can inform targeted public health strategies. Methods: A retrospective analysis of medical records from the HIV clinic in Wroclaw was conducted for the years mentioned. The dataset included demographic information, transmission routes, clinical status, and co-infections. Results: The study included 202 patients, of whom 27 were women. Heterosexual transmission was the primary route among women (2010/2016/2020 – 44.44%/57.14%/90.91%), while men predominantly acquired HIV-1 through homosexual contact (2010/2016/2020 – 52.94%/80.82%/75%). A significant decrease in infections from intravenous drug use was observed among men (Chi² = 24.85, df = 2, p < 0.001). Women consistently had lower CD4+ T cell counts, with a median (Q1, Q3) of 250 (108– 288), significantly lower than men’s 431 (280– 550) (Mann–Whitney U-test: z = 4.23, p < 0.001). Women were also more frequently diagnosed as late presenters (OR: 6.07, 95% CI (2.34– 15.82)). Conclusion: This study identifies significant gender disparities in HIV-1 diagnosis in Lower Silesia, with women being six times more likely to be diagnosed as late presenters. This highlights the necessity for enhanced and targeted public health interventions, particularly within the context of antenatal care.

Introduction: Creatine is a naturally occurring compound vital for energy metabolism, particularly in high-energy-demand tissues like muscles and the brain. Traditionally, research on creatine has focused on its ergogenic effects in sports, but emerging research suggests it may also positively impact brain health. Studies are exploring creatine monohydrate's role in improving cognitive function, mitigating neurodegenerative processes, and supporting mental health. This dual functionality highlights the compound's versatility as both a performance enhancer and a potential therapeutic agent for neurological health. By expanding the scope of creatine research beyond physical performance, we can better understand and utilize its full capabilities to enhance human health. This research review examines the growing evidence suggesting that creatine supplementation could significantly benefit brain health and the management of neurological diseases. Aim of the study: This review aims to synthesize current findings on creatine's cognitive benefits and its therapeutic potential for neurological disorders, critically analyzing preclinical and clinical studies to identify gaps and suggest future research directions.Materials and Methods: A comprehensive literature search was conducted using PubMed and Google Scholar databases, covering studies published between 2000 and 2024. Keywords such as creatine supplementation, brain health and neurodegeneration were used. Exclusion criteria included non-peer-reviewed articles, studies with insufficient data, and those not in English. Conclusions: This review highlights the potential benefits of creatine supplementation for cognitive and neurodegenerative diseases, noting its positive effects on memory, alleviating depression and anxiety, and offering neuroprotection. Future research should aim to standardize dosing, extend follow-up periods, and include larger, more diverse populations.

Creutzfeldt-Jakob disease (CJD) is a rare condition. In this study we describe the diagnosis of the disease in a 73-year old female, presenting dementia. Diagnostic tests unveiled characteristic features of CJD. The diagnosis of CJD was confirmed. It is important to always take into consideration the diagnosis of CJD in the diagnostic process of dementia. Purpose: The aim of this scientific paper is to present symptoms and diagnostic methods of Creutzfeldt-Jakob disease on the basis of a clinical case. Review Methods: We conducted our study as a literature review based on information gathered from PubMed, Embase, GoogleScholar using combinations of the following. As a part of study, we also present a case description from our materials from clinical practice.
