Globally, breast cancer is both the most common cancer and the most common cause of death related to cancer among women. It is estimated that over 2 million women were diagnosed with breast cancer in 2022 worldwide, while almost 400,000 were diagnosed in the EU. Breast cancer has different histopathological subtypes that require different therapeutic approaches. Triple-negative breast cancer (TNBC) is a type that is considered more aggressive; it occurs in about 10 to 20% of all breast cancer cases. Approximately 40% of women initially diagnosed with TNBC will develop metastases. The objective of this study is to present current clinical trials focused on new treatment of advanced and metastatic TNBC. The study was conducted by searching the clinicaltrials.gov database. Due to the scope of this paper, primary endpoints in the included studies were objective response rate, treatment-emergent adverse events or serious adverse events, progression-free survival, and probability of pathologic complete response. Some of the selected studies were phase I or II RCTs; therefore, we should carefully examine their future results and implications for clinical guidelines.

Tele-dentistry is a rapidly growing field, especially in the era of the COVID-19 pandemic. Due to the COVID-19 pandemic, remote services are of increasing interest to both patients and dental personnel. They allow for reduced person-to-person contact and thus a reduced risk of transmission of the SARS-CoV2 virus. The COVID-19 pandemic has affected the functioning of all areas of life, including dental treatment. The aim of the study was to assess the possibility of using tele-dentistry for dental services and analyse the attitudes of patients and dentists towards this solution. The period analysed was between March 2019 and February 2021 in five healthcare entities in Cracow in Central Europe. The study’s retrospective analysis shows a positive attitude of patients towards tele-dentistry at every stage of treatment, from diagnosis through postoperative care, and a significant reluctance of dentists in the majority of dental specialties towards tele-dentistry. Consequently, a significant percentage of patients were invited to dental offices for a face-to-face appointment during the COVID-19 pandemic. The negative attitude of dental personnel towards tele-dentistry compared with the positive attitude of patients towards tele-dentistry is somewhat worrying in view of the possibility of a further pandemic. At the same time, it provides important information about the need to educate and support dental personnel in tele-dental solutions and improve solutions for the future. Taking into account the potential reduction in dental care costs for patients and countries after the implementation of tele-dentistry solutions, this is an important topic, while current studies do not comprehensively address the attitudes of patients and dental personnel towards tele-dentistry. In other parts of the world, a similar approach to tele-dentistry is used by patients and dentists.

Clostridioides difficile is an anaerobic, Gram-positive bacterium widely present in the hospital environment due to its ability to generate spores. The transfer of spores to patients through the hands of medical personnel is one of the most frequent paths of C. difficile transmission. In paediatric patients burdened with a serious primary illness requiring long-term hospitalisation and antibiotic therapy, C. difficile may be a significant risk factor for antibiotic-associated diarrhoea. The goal of the study was to assess the state of hospital environments as a potential source of C. difficile spores and to establish the share of hyperepidemic strains at the two paediatric units. The survey for C. difficile was conducted with a C. diff Banana BrothTM medium, used to detect spores and to recover vegetative forms of the bacteria. Environmental samples (n = 86) and swabs from the clothing of medical personnel (n = 14) were collected at two units of a paediatric hospital, where the cases of antibiotic-associated diarrhoea with a C. difficile aetiology constitute a significant clinical problem. In 17 samples, a change in the broth’s colour was observed, indicating the presence of spores. Out of seven samples, C. difficile strains were cultured. The pathogenic isolates of C. difficile were obtained from swabs collected from elements of beds, a toilet, a door handle and a doctor’s uniform. In our study, we indicated points of increased risk of pathogen transmission, which could constitute a source of infection. The clothing of medical personnel may be a dangerous carrier of pathogenic spores. Periodical surveys of hospital environments with the use of specialist microbiological mediums successfully indicate the direction of corrective actions to be undertaken by the medical facility in order to increase patient safety.

In 2020 it is estimated that 281 million people were international migrants. Migrants constitute a potentially vulnerable population in terms of facing discrimination, poor living and housing conditions, and insufficient access to healthcare services. Due to the armed conflict in Ukraine in 2022, almost 10 million people crossed the Polish border within a year of the outbreak of the conflict. The objective of this paper is to present the use of primary healthcare services by people migrating from Ukraine to Poland and identify the barriers in access to healthcare by this group of persons. This study used a qualitative research technique in the form of an expert interview using individual in-depth interviews (IDI). The study group consisted of professionally active primary healthcare providers (doctors, nurses, and facility managers) in Poland. Research was carried out in the areas regarding the availability of healthcare, the potential threats and challenges, and possible system solutions. The results showed that the most common cause for doctor’s appointments among migrants are respiratory infections, including COVID-19. Many cases were related to back pain, mainly resulting from the physical work of the patients. Additionally, some barriers to access and the provision of healthcare services for patients from Ukraine were identified. The majority (75%) of respondents indicated language as a significant barrier when providing services. Based on the study results, we recommend creating a dedicated website and telephone hotline for this group of persons as well as the use of traditional media to distribute information about access to healthcare services. It is also essential to focus on assistance for older people, since they may experience more difficulties with language and navigating the healthcare system.

Proper oral health care has an impact on the health of the entire body. The COVID-19 pandemic has affected the functioning of the healthcare sector, including dental services. The aim of this study was to analyse the behaviour of patients with regard to their use of dental services during the pandemic. The data were obtained from paper registration forms taken from five dental offices in the city of Cracow between March 2019 and February 2021. During the analysed periods, interest among first-time patients in dental services decreased to 37% (during the month when interest in dental services was at its lowest) compared to the year preceding the COVID-19 pandemic. The number of cancelled visits increased by between 15% and 50% compared to the pre-pandemic period. During the pandemic, appointments made by existing patients increased by up to 84% compared to 2019. The decision by patients to postpone dental treatment not only has adverse effects on their oral and body health, but in turn results in higher health care costs. Given the potential for another pandemic, further long-term research is required to develop and implement special protocols to make the public aware of the safety of health care.

Screening is widely considered one of the most effective methods for the early detection of prostate cancer. Early detection allows for prompt treatment, which increases the likelihood of a full recovery. This review sought to summarize studies on screening methods related to prostate cancer. It examined trends in screening practices and organized the findings into two main categories. The first category focused on strategies to boost screening participation, reach underserved populations, and improve public awareness of health issues. The second category concentrated on refining current diagnostic methods, developing new tests, and testing biomarkers. A significant portion of the research also explored diagnostic techniques aimed at enhancing patient comfort during exams without compromising clinical effectiveness.
