Background: Chemotherapy drugs are widely used to treat cancer, but their active compounds represent a danger for workers who could be exposed to them. However, they aren't yet included in directive CE No. 1272/2008 and the European Biosafety Network has only recommended a limit value of 100 pg/cm² for surface contamination. Thus, it is crucial to assess surface contaminations in healthcare environments. Currently, the technique of choice is surface wipe test combined with liquid chromatography tandem mass spectrometry to achieve high sensibility.

Material and methods: A campaign involving Careggi University Hospital (Florence, Italy) was performed from January 2020 to December 2021, collecting 1449 wipe samples between administration units, preparation unit, and personnel gloves. From the obtained data, the 90th percentile was calculated for 30 antiblastic drugs and proposed as surface exposure levels (SELs); while from data concerning personnel glove contamination, weekly contamination was estimated.

Results: In the 2-year period only 417 wipe samples were found positive (28.8%), the majority of which regard samples coming from administration unit bathrooms. The proposed SELs are almost all <100 pg/cm², except for few drugs which produce higher contamination on bathroom surfaces. Also, the estimation of pharmacy personnel's glove contamination highlighted very low results (ng/week).

Conclusions: Deeply established protocols and procedures for safe handling of ADs allow for obtaining excellent cleaning results and thus a safer work environment, however, the risk of cytostatic contaminations cannot be avoided in healthcare workplaces, and thus a harmonization of classification and labeling of chemotherapy drugs throughout the European Union should be done.

Background: The aim of the study was to assess the state of knowledge of Medical University of Warsaw (MUW) students on COVID-19, modes of transmission and preventive measures.

Material and methods: The study was conducted in October 2020. The participants were all the students attending classes at MUW - 8922 persons. All had completed the online training "Work safety and hygiene during COVID-19." To assess their state of knowledge an online questionnaire was made available on the MUW e-learning platform. The questionnaire comprised 4 parts: (1) awareness of rules of hand hygiene, (2) medical aspects of COVID-19, (3) preventing SARS-CoV-2 infection transmission in health care facilities, and (4) preventing infection transmissions in the society.

Results: The majority of students (93.9%) demonstrated a sufficient level of knowledge. The highest passing threshold was found on the medical programme (96.7% of students with satisfactory level of knowledge), dentistry (96.2%) and pharmacy (95.5%). The statistically significant factors that differentiated student results proved to be faculty (p < 0.001), study programme (p < 0.001), year of studies (p = 0.001), form of studies (p < 0.001). The participants most often showed full knowledge (100% correct answers in sub-area) of preventing infection transmissions in the society (93.3%) and medical aspects of COVID-19 (91.8%), less complete in terms of ways of preventing infection transmission in health care facilities (85.4%), and in particular hand hygiene rules (78.3%). All the variables characterizing academic status (study programme, faculty, year and form of studies) were statistically significant differentiating factors for students' full knowledge in all of the 4 analyzed sub-areas, while students' sex only in the sub-area of COVID-19 medical aspects.

Conclusions: There is a clear need for conducting systematic educational activities among students of all medical study programmes and assessing their level of knowledge in those areas that were identified as least frequently controlled, namely, hand hygiene and infection transmission in health care facilities.

Background: Studies of influenza, and human coronaviruses provide evidence that the use of a medical mask can prevent the spread of infectious droplets from an infected person to someone else. After global public health emergency of coronavirus SARS-CoV-2 causing illness of COVID-19 was changing frequency of wearing a mask. Therefore, study was undertaken to assess whether the use of protective masks affects the level of oxygen saturation during rest and during exercise.

Material and methods: The test consisted of a non-invasive measurement of oxygen saturation by percutaneous determination of arterial oxygen saturation with the use of the pulse oximeter. Oxygen saturation was measured during rest and after physical exertion performed without a protective mask (2 types of masks were used: surgical and FFP2), as well as during rest and after physical exertion performed with the use of a protective mask. The analysis of the oxygen saturation, heart rate, blood pressure and respiratory rate included data on 48 subjects.

Results: Comparing the post-exercise and pre-exercise values showed a significant difference between all of them. There were no differences found in any variables according to the mask/no-mask status.

Conclusions: A short-term physical exercise performed in a group of healthy young people using protective masks did not affect oxygen saturation, heart rate, blood pressure and respiratory rate. Med Pr. 2022;73(5):363-68.

Background: This article presents the verification of the factor structure and validation of the Polish version of the Short Version of the Occupational Self-Efficacy Scale (SVOSES), developed by Rigotti et al.

Material and methods: The study was questionnaire-based and took place in a "paper-and-pencil" format. They were conducted on 2 independent samples of 1261 and 205 employees, respectively. The factor structure of the tool was checked by means of confirmatory factor analysis (CFA). Its reliability was calculated using 2 methods - Cronbach's α measure (internal consistency) and test-retest method (temporal stability). The theoretical validity of the scale was estimated using correlation analysis in which the criterion variables were: meaning of work, job satisfaction, general self-efficacy, psychological stress symptoms, somatic stress symptoms, and burnout.

Results: The univariate structure of the scale was confirmed, consistent with the original version, as well as the theoretical validity and reliability.

Conclusions: The Polish version of the SVOSES can be used as a diagnostic instrument for research in the field of mental health at work, as well as in practical activities, e.g., career counseling, recruitment, selection or screening. Med Pr. 2022;73(4):325-36.
