Healthcare-associated infections (HAIs) occurring in patients treated in an intensive care unit (ICU) are serious complications in the treatment process. Aetiological factors of these infections can have an impact on treatment effects, treatment duration and mortality. The aim of the study was to determine the prevalence and microbiological profile of HAIs in patients hospitalized in an ICU over a span of 10 years. The active surveillance method was used to detect HAIs in adult patients who spent over 48 h in a general ICU ward located in southern Poland between 2007 and 2016. The study was conducted in compliance with the methodology recommended by the Healthcare-associated Infections Surveillance Network (HAI-Net) of the European Centre for Disease Prevention and Control (ECDC). During the 10 years of the study, 1849 patients hospitalized in an ICU for a total of 17,599 days acquired 510 with overall HAIs rates of 27.6% and 29.0% infections per 1000 ICU days. Intubation-associated pneumonia (IAP) posed the greatest risk (15.2 per 1000 ventilator days), followed by CLA-BSI (8.0 per 1000 catheter days) and CA-UTI (3.0 per 1000 catheter days). The most common isolated microorganism was Acinetobacter baumannii (25%) followed by Coagulaase-negativ staphylococci (15%), Escherichia coli (9%), Pseudomonas aeruginosa (8%), Klebsiella pneumoniae (7%), Candida albicans (6%). Acinetobacter baumannii in 87% and were classified as extensive-drug resistant (XDR). In summary, in ICU patients pneumonia and bloodstream infections were the most frequently found. Acinetobacter baumannii strains were most often isolated from clinical materials taken from HAI patients and showed resistance to many groups of antibiotics. A trend of increasing resistance of Acinetobacter baumannii to carbapenems was observed.

Background: The quality of medical services for a child and their parents are tantamount to a sense of satisfaction with care. Purpose: The assessment of determinants of parental satisfaction with nursing care in paediatric wards. Methods: The study covered 336 parents of children hospitalised in paediatric departments and was based on the “EMPHATIC” questionnaire, standardized and adapted to Polish conditions. Results: The mean score of the overall parental satisfaction was high, amounting to 4.19 points. The lower level of satisfaction with nursing care was reported in parents of children under the age of 6 years, admitted in an emergency mode with a diagnosed post-trauma condition and those with higher education. The duration of hospitalisation, sex and age of parents did not have an influence on the satisfaction with care. Conclusions: The age of the child, admission mode and education of respondents are determinants of parental satisfaction with nursing care.

Aim To study the relationship between Polish nurses' working conditions and their attitudes towards patient safety during the COVID‐19 pandemic. Background Facing the COVID‐19 pandemic, caused by the SARS‐CoV‐2 virus, healthcare worldwide has been reorganised. How these changes affected patient safety for hospitalised persons is not well understood. Introduction Difficult working conditions related to the outbreak of the COVID‐19 pandemic may affect the provision of safe and effective care by healthcare staff. Methods This observational research was performed on the group of 577 nurses working during the COVID‐19 pandemic in isolation infection wards ( n = 201) and non‐infectious diseases wards ( n = 376) in Polish hospitals. The evaluation of working conditions was performed with an author's questionnaire, while the evaluation of factors influencing attitudes towards safety of the hospitalised patients was performed using Safety Attitudes Questionnaire. The STROBE checklist was used to report this study. Results The procedures developed by management in advance for COVID‐19 patient treatment had a statistically significant influence on nurses' ‘evaluation of teamwork climate, safety climate, job satisfaction, perception of management and work conditions’. Providing management with the ability to perform a swab polymerase chain reaction SARS‐CoV‐2 test for hospital staff in the workplace, and psychological support from professionals and employers were statistically significant for higher ratings of ‘teamwork climate, safety climate, job satisfaction, stress recognition, perception of management and work conditions’ by the Polish nurses. Hospital workload during the COVID‐19 pandemic was significantly correlated with lower evaluation of work conditions. Discussion Our study reinforces the existing literature on many fronts and demonstrates how even when operating under the COVID‐19 pandemic conditions, some factors remain critical for fostering a culture of patient safety. Reinforcing patient safety practices is a imperative under these conditions. Conclusions and implications for nursing Working conditions influence nurses' attitudes towards safety of the hospitalised patients. These are largely modifiable factors related to the workplace and include prior preparation of procedures, restrictions to extending daily work hours and psychological counselling for the staff.

Background: The hospitalization of patients treated in the intensive care unit (ICU) in 5-15% of cases is associated with the occurrence of a complication in the form of ventilator-associated pneumonia (VAP). Purpose: Retrospective assessment of risk factors of VAP in patients treated at ICUs in the University Hospital in Krakow. Methods: The research involved the medical documentation of 1872 patients treated at the ICU of the University Hospital in Krakow between 2014 and 2017. The patients were mechanically ventilated for at least 48 h. The obtained data were presented by qualitative and quantitative analysis (%). The qualitative variables were compared using the Chi 2 test. Statistically significant was the p < 0.05 value. Results: VAP was demonstrated in 23% of all patients treated in ICU during the analyzed period, and this infection occurred in 13% of men and 10% of women. Pneumonia associated with ventilation was found primarily in patients staying in the ward for over 15 days and subjected to intratracheal intubation (17%). A statistically significant was found between VAP and co-morbidities, e.g., chronic obstructive pulmonary disease, diabetes, alcoholism, obesity, the occurrence of VAP and multi-organ trauma, hemorrhage/hemorrhagic shock, and fractures as the reasons for admitting ICU patients. Conclusions: Patients with comorbidities such as chronic obstructive pulmonary disease, obesity, diabetes, and alcoholism are a high-risk group for VAP. Particular attention should be paid to patients admitted to the ICU with multi-organ trauma, fractures, and hemorrhage/hemorrhagic shock as patients predisposed to VAP. There is a need for further research into risk factors for non-modifiable VAP such as comorbidities and reasons for ICU admission in order to allow closer monitoring of these patients for VAP.

Malassezia is a genus of lipophilic yeasts residing on the skin of warm-blooded animals. The correlation between specific species and their involvement in skin diseases has been well researched. However, only very few studies have investigated the distribution of Malassezia spp. on the healthy skin of patients infected with human immunodeficiency virus (HIV). The purpose of this work was to analyze whether the composition of Malassezia spp. isolated from the skin of the HIV-infected patients differs from that of healthy individuals. The study included a total of 96 subjects, who were divided into two equally sized groups: HIV-seropositive and HIV-seronegative. The specimens were collected from the subjects by swabbing four anatomical sites (face, chest, back, and scalp). Species were identified using phenotype-based methods, and the identification of strains isolated from the HIV-seropositive patients was confirmed by PCR sequencing of the rDNA cluster. Malassezia spp. were isolated from 33 (69%) HIV-seropositive patients and 38 (79%) healthy volunteers. It was found that men were much more likely to have their heads colonized with Malassezia spp. than women. The most prevalent species on the skin of both HIV-seropositive and HIV-seronegative individuals were Malassezia sympodialis, M. globosa, and M. furfur, albeit at different proportions in the two populations. The diversity of Malassezia spp. was the highest on the face of the HIV-seropositive patients (Shannon–Weiner Index H = 1.35) and lowest on the back of the healthy volunteers (H = 0.16). The phenotype- and molecular-based identification methods were congruent at 94.9%. It was observed a tendency that the HIV-seropositive patients had higher CD4+ cell counts, indicating higher colonization with Malassezia spp.

Abstract Context Recent studies have outlined the potential role of dietary factors in patients who have survived cancer. Objective The aim of this study was to summarize the evidence of the relation between dietary intake of phytoestrogens and their blood biomarkers and, overall, cancer-specific mortality and recurrence in patients with cancer. Data Sources A systematic search of PubMed, EMBASE, and Web of Science databases of studies published up to September 2019 was performed. Databases were searched for prospective and retrospective cohort studies reporting on dietary phytoestrogen intake and/or blood biomarkers and the outcomes investigated. Data extraction Data were extracted from each identified study using a standardized form. Data analysis Twenty-eight articles on breast, lung, prostate, and colorectal cancer, and glioma were included for systematic review. Given the availability of studies, a quantitative meta-analysis was performed solely for breast cancer outcomes. A significant inverse association among higher dietary isoflavone intake, higher serum/plasma enterolactone concentrations, and overall mortality and cancer recurrence was found. Among other cancer types, 2 studies reported that higher serum enterolactone and higher intake of lignans were associated with cancer-specific survival for colorectal cancer and glioma, respectively. Conclusions Dietary phytoestrogens may play a role in survival from breast cancer ; evidence regarding other cancers is too limited to draw any conclusions.

Objectives: The basic care requirement for patients with weakened immune systems is to create the environment where the risk of mycosis is reduced to a minimum. Material and Methods: Between 2007 and 2013 air samples were collected from various wards of a number of hospitals in Kraków, Poland, by means of the collision method using MAS-100 Iso MH Microbial Air Sampler (Merck Millipore, Germany). The air mycobiota contained several species of fungi, and almost 1/3 of it was made up of the species of the Aspergillus genus. Sixty-one strains of species other than A. fumigatus were selected for the research purposes, namely: 28 strains of A. ochraceus, 22 strains of A. niger and 11 strains of A. flavus species. Selected fungi underwent a cytotoxicity evaluation with the application of the MTT colorimetric assay (3-(4,5-dimethylthiazol-2-yl)-2,5-di phenyltetrazolium bromide). The assay assesses cell viability by means of reducing the yellow tetrazolium salt to insoluble formazan. A semi-quantitative scale for cytotoxicity grading was adopted: low cytotoxic effect (+) with half maximal inhibitory concentration (IC 50 ) for values ranging from 31.251 cm 2 /ml to 7.813 cm 2 /ml, medium cytotoxic effect (++) for values ranging from 3.906 cm 2 /ml to 0.977 cm 2 /ml and the high one (+++) for values ranging from 0.488 cm 2 /ml to 0.061 cm 2 /ml. The absence of cytotoxicity was determined when the IC 50 values was at ≥ 50. Results: For 48 samples the analyzed fungi displayed the cytotoxic effect with A. ochraceus in 26 out of 28 cases, with 11 strains displaying the high cytotoxic effect. The lowest cytotoxicity was displayed by fungi of A. niger in 13 out of 22 cases, and the major fungi of A. flavus species were toxic (9 out of 11 cases). Conclusions: A half of the fungi displayed the low cytotoxic effect. On the basis of the comparison of average cytotoxicity levels it was determined that there were significant differences in the levels of cytotoxicity of the analyzed fungi. However, such statement may not provide grounds for a definite conclusion about the compared species of fungi that display a more cytotoxic effect than others.
