The aim of this study was to investigate the level of posttraumatic growth of cancer patients post-treatment in the context of selected sociodemographic characteristics, clinical markers, and psychological variables (positive and negative emotions, anxiety and depressive symptoms, gratitude, forgiveness, hope, importance of the spiritual aspect of life and the practice of religious faith). The study sample consisted of 110 patients post-treatment aged 22-79 years and with an average time since the completion of the last treatment ranging from 5 to 396 months. The Posttraumatic Growth Inventory, the Positive and Negative Affect Schedule, screening methods to measure anxiety (General Anxiety Dis- order-7) and depression (Patient Health Questionnaire-9), and questionnaires to measure dispositional gratitude (Gratitude Questionnaire GQ-6), dispositional hope (Adult Dispositional Hope Scale), and forgiveness (Heartland Forgiveness Scale) were used to measure the psychological variables. There were no differences in the level of posttraumatic growth in terms of sociodemographic characteristics and clinical markers. Partner status, employment status, presence of recurrence, and comorbidities did not differentiate its level either. The rate of posttraumatic growth was related to the experience of positive emotions, gratitude, the importance of the spiritual aspect of life, and the practice of religious faith. In the regression model that explained 21.90% of the variance in posttraumatic growth, only the level of positive emotions was a significant predictor. The results of the present research point suggest that the level of posttraumatic growth is associated with several areas of emotional experience and cognitive adjustment of cancer patients post-treatment.

The research and analysis of the bactericidal properties of the spacer knitted fabric with the UV-C system are presented in this paper. The disintegration factor affecting the bacteria in the knitted fabric is the UV-C radiation in the range of 265–270 nm distributed via woven optical fibres. The way of integrating elements of the system generating the UV-C radiation in the structure of the spacer knitted fabric was designed, as well as various configurations of optical fibres arrangement, fibre density, number of radiation sources, and diode types were tested. The material was contaminated with selected microorganisms indicative of sanitary contamination and important in terms of nosocomial infections. The scope of the research included microbiological (quantitative and qualitative) analyses of selected taxonomic groups of microorganisms (mesophilic bacteria, fungi, actinomycetes) before and after the irradiation process. The analysis of the research results and the applied modification of the knitted fabric turned out to be effective in reducing the amount of potentially pathogenic microorganisms.
