Sources of parental knowledge about the safety of vaccinations in Poland.

There has been a recent increase in the number of parents refusing vaccination for their children in many European countries, including Poland. This observation necessitates the need to understand parental knowledge in regard to mandatory vaccination of children in these countries. A cross-sectional survey was conducted in 2016 on 1239 parents or legal guardians of preschool and school children in the Silesian Voivodship (Poland) to evaluate their hesitancy in acquiescing to their children mandatory immunization and the relation to this habit in regard to the use of informational sources on children vaccination system in Poland. Medical doctors often provide the basic source of information about vaccination to parents. About one-third (29%) of the respondents from the survey deemed the qualification system for vaccination as either inadequate or bad. 16.9% of the respondents surveyed declared that information received from physicians regarding vaccinations were either incomplete or unconvincing. Results of multivariable analyses confirmed that respondents are less likely to seek information about mandatory vaccinations from medical professionals and more often to misjudged vaccination's qualification system. Participants who used less informative sources (e.g. leaflets) and those with a lower level of education were more likely to avoid vaccination. Greater emphasis on the quality of information provided by medical professionals is crucial in order to avoid doubts about vaccination and to create proper attitudes and adherence to vaccination schedules.

The Web-Based Randomized Controlled Intervention as the Enhancer of Cancer Prevention.

Background and Objectives: Cancer is an unresolved public health issue in society. With the advent of the internet and the development in the technological sector, access to basic health-related information has become more frequent among patients and healthy individuals. The aim of this study is to evaluate the impact of educational intervention on the participant's willingness to undergo selected medical procedures in case of suspected cancer. Materials and Methods: From 14 May 2015 to 13 November 2016, a total of 1118 who visited the Polish scientific website were enrolled in the 'Polish Online Randomized Intervention aimed at Neoplasm Avoidance' (PORINA) and randomized into two groups (educational and control). The original Cancer Knowledge Index (CKI) was used for the evaluation of participants' cancer-related knowledge. They were asked to declare whether they would consent to undergo selected medical procedures necessary for cancer diagnosis or treatment. Results: Most participants declared their readiness to undergo abdominal ultrasonography, computed tomography, and a nevi excision. The most noticeable changes were found for potential consent to undergo breast fine needle aspiration, mammography and gastroscopy. Conclusions: The level of oncological knowledge has an impact on individual decision to consent to particular medical procedures. Conducted educational intervention has significantly increased the readiness to undergo selected medical procedures.

The role of an electronic questionnaires in epidemiologic studies aimed at cancer prevention

The growing number of people diagnosed with cancer is an important issue in public health. Evaluation of the population's level of cancer-related knowledge is mandatory for planning effective prevention or intervention programs. Until recently, traditional methodology, using paper questionnaire or telephone-based interviews had dominated previous cross sectional studies related to this issue. Currently, the use of new research methods based on information technology solutions has been more frequent. Therefore, the aim of this paper is to review published data available in the PubMed database towards the identification of strengths and weaknesses of crosssectional studies conducted via Internet, a type of information technology solution. This review allowed the authors to conclude that web-based questionnaire studies could be an effective solution and may possibly replace traditionally conducted interviews. Likewise, it evidently appears that an online mode is more adequate for querying young people. However, there is lack of consensus regarding the cost-effectiveness of the application of Web technology as a research tool for epidemiological questionnaire-based studies. Data security was revealed to be an important aspect of conducting Internet-based questionnaire studies. Further efforts are aimed at standardizing this type of researches to assess their strengths and weaknesses leading to more widespread use.

Melanoma awareness and prevalence of dermoscopic examination among internet users: a cross-sectional survey.

INTRODUCTION: Melanoma presents the greater threat to health the later the disease is detected and treated, although treatment results can be improved by the widespread use of dermoscopy. However, scarce data are available concerning the awareness of dermoscopy and the frequency of its performance in the non-patient population. AIM: To assess the awareness of melanoma detection by dermoscopic examination among the audience of a scientific website. MATERIAL AND METHODS: Respondents were invited to participate in an online cross-sectional survey. They were asked to complete an online questionnaire designed by the authors. The preliminary analysis of 5,154 collected forms and the exclusion of incomplete forms yielded 4,919 fully completed questionnaires; the resulting database was analyzed statistically using logistic regression with the R software program (95% CI). RESULTS: Less than two-fifths (39.2%) of respondents reported ever having sought the advice of a medical professional (dermatologist or other specialist), and 25.4% of the respondents had undergone dermoscopy at least once in their life. Furthermore, approximately one-tenth of respondents (10.7%) were not aware of this detection tool. The study respondents gained knowledge about dermoscopic examination from television and magazines. The performance of dermoscopy was more increasingly associated with inhabitants of larger locales, the use of higher-SPF sunscreens, and greater awareness of the relationship between the risk of melanoma and sunburn. CONCLUSIONS: Awareness of melanoma and sun care varied within the analyzed population. A subset of individuals at high risk of melanoma was identified. This group included those who engaged in risky sun exposure behaviors and who had never been examined by dermoscopy.

"Better do not touch" and other superstitions concerning melanoma: the cross-sectional web-based survey.

INTRODUCTION: To the authors' best knowledge, there are no data regarding the prevalence of superstitions concerning melanoma among internet users. AIM: To evaluate the prevalence and identify reasons for superstitions associated with excision of pigmented skin lesions as well as to assess the frequency of this procedure. MATERIAL AND METHODS: Readers of the scientific portal were invited to complete a fully anonymous e-questionnaire. After collection of questionnaires (5,154) and eliminating incomplete ones, 4,919 surveys were analysed. RESULTS: A total of 4,104 (83.4%) respondents have been aware that the total surgical excision is the only efficient way of melanoma treatment. This familiarity was related to increased skin cancer awareness but was not linked to regular skin self-examination. Over half of the surveyed agreed that "it is better not to touch naevi". Moreover, 3,510 (71.3%) individuals believed that naevi located in "harmed places" may turn into melanoma. CONCLUSIONS: Superstitions associated with surgical treatment of melanoma are widespread. Conducting educational campaigns is necessary, particularly among young people, whose dangerous tanning behaviours are important risk factors for melanoma occurrence in their later life.

Bleeding gastric metastases from cutaneous melanoma.

UNLABELLED: 7% of gastrointestinal tract (GIT) involvements with metastatic cutaneous melanoma concerns the stomach. The aim of the study was to describe a rare case of the cutaneous melanoma metastazing to the stomach. MATERIAL AND METHODS: . Bearing in mind the rarity of such cases, we present our experiences based on the history of 42-year-old woman, who underwent surgical excision of skin tumour located on the trunk. RESULTS: Histopathological examination of the skin tumor led to the diagnosis of melanoma (Clark IV, Breslow 5mm) with ulceration and a number of mitoses 40/10 HPF. PET-CT demonstrated multiple organ dissemination. Patient was admitted to the hospital due to severe, symptomatic anaemia. RBC and FFP transfusions were necessary. Gastroscopy revealed multiple gastric and duodenal ulcers and histopathology confirmed metastatic melanoma. Attempts to achieve endoscopic hemostasis were ineffective due to the extent of lesions. CONCLUSION: In the presence of any alarming GIT symptoms or unclear anaemia, any physician treating patient with a history of melanoma should exclude metastatic tumour. Endoscopy may be useful both for the diagnosis and local treatment of gastric metastases and should be routinely and cautiously conducted.

Changes in alcohol consumption among medical students during the COVID-19 pandemic - results from POLLEK study.

OBJECTIVES: Social distancing and remote learning as one of the ways to fight against COVID-19 pandemic have affected universities and changed the lifestyle of many students. Psychoactive substances use was one of the way to deal with the anxiety caused by these new settings. Studies published so far have not provided a clear answer on whether COVID-19 leads to changes in the structure of alcohol consumption among medical students. The presented study attempted to answer this question based on the data available from the POLLEK study. MATERIAL AND METHODS: The study group included 3 separate groups of medical students (recruited in the following academic years: 2019/2020, 2020/2021, and 2021/2022) with a total number of 899 students. To assess the characteristics of alcohol consumption the authors used a Polish version of the Alcohol Use Disorder Identification Test (AUDIT). RESULTS: Students surveyed during the lockdown lived in the family home much more often, reported good health, and declared consumption of a smaller number of alcoholic beverages. Their AUDIT scores were statistically significantly (p = 0.04) lower compared to the group surveyed before the pandemic (5 vs. 6, respectively). There were no significant differences in the AUDIT results between other study periods. CONCLUSIONS: Lockdown due to COVID-19 pandemic might be associated with a decrease in alcohol intake among medical students. This may be due to a different place of residence of students, a family home rather than a dormitory. However, the debate on this topic seems to be still open. Int J Occup Med Environ Health. 2023;36(3):406-16.

The Association between COVID-19 Pandemic and the Quality of Life of Medical Students in Silesian Voivodeship, Poland.

(1) Background: Since the COVID-19 pandemic spread rapidly in 2020, medical universities have been affected by a particular crisis. Due to the increased risk of SARS CoV-2 transmission, the authorities of medical faculties all over the world, including Poland, started to minimize direct contact between students. The objective of the paper is to identify and assess determinants of the quality of life among medical students in Poland before and during the COVID-19 pandemic. (2) Methods: We analyzed data obtained in a cross-sectional study performed among three groups of students tested in three consecutive research periods: period before the COVID-19 pandemic, the COVID-19 pandemic lockdown period and the COVID-19 pandemic period following lockdown. (3) Results: The total number of participants was 1098. We identified that the research period before the COVID-19 pandemic was the risk factor for lower quality of life in terms of the somatic and environmental domains. It was also confirmed that determinants such as poor financial situation, low frequency of physical activity and bad self-declared health status harmed the QoL scores in all domains. (4) Conclusions: The obtained results confirmed that better financial situation, higher physical activity and better self-declared health status were statistically significant factors improving the quality of life of first-year medical students in Poland. The findings of our study also showed that the declared somatic and environmental domains of QoL among medical students were better during the COVID-19 pandemic period. Our observations confirmed that the immediate implementation of e-learning could protect against the deterioration of mental health and quality of life in first-year medical students during possible future epidemic crises.

Limitation of Futile Therapy in the Opinion of Nursing Staff Employed in Polish Hospitals-Results of a Cross-Sectional Study.

The debate on limiting futile therapy in the aspect of End of Life (EoL) care has been going on in Poland over the last decade. The growing demand for EoL care resulting from the aging of societies corresponds to the expectation of a satisfactory quality of life and self-determination. The authors designed a cross-sectional study using a newly designed questionnaire to assess the opinions of 190 nurses employed in intensive care units (ICUs) on futile therapy, practices, and the respondents' approach to the issue. The problem of futile therapy and its clinical implications are known to the nursing community. Among the most common reasons for undertaking futile therapy in adult patients, the respondents declared fear of legal liability for not taking such actions (71.58%), as well as fear of being accused of unethical conduct (56.32%), and fear of talking to the patient/patient's family and their reaction (43.16%). In the case of adult patients, the respondents believed that discontinuation of futile therapy should be decided by the patient (84.21%), followed by a doctor (64.21%). As for paediatric patients, two-thirds of the respondents mentioned a doctor and a court (64.74% and 64.21%, respectively). Overall, 65.26% of the respondents believe and agree that the comfort of the patient's last days is more important than the persistent continuation of therapy and prolonging life at all costs. The presented results clearly show the attitude of the respondents who defend the patient's dignity and autonomy.

Limiting futile therapy as part of end-of-life care in intensive care units.

The debate about medical futility often involves intensive care units where life-support procedures are routinely applied. Futile therapy is part of end-of-life therapy. In the discussion about medical futility it is important to distinguish the effect of therapy from the benefit for the patient. The goal of treatment is not to maintain the function of an organ, body part or physiological activity, but to maintain health as a whole. Prolonging ineffective treatment violates the standard of good medical practice. In 2014, the first Polish guidelines on limiting futile therapy in patients treated in intensive care units were published. This document presents the official position of intensive care experts consulted by medical societies of other medical disciplines. Limitation of futile therapy by withdrawing from already used treatments or withholding new therapies does not mean that the role of medical personnel has ended. Intensive care turns into palliative care. The list of comorbidities showing a statistically significant correlation with medical futility has been refined. These include heart failure (NYHA III/IV), neoplastic disease and disseminated neoplastic process, and failure of two or more organs. The published survey results are devastating; 66-89% of intensive care nurses have provided futile treatment in their careers. Intensivists estimated that, on average, 20% of patients in intensive care units receive futile therapy. There is a need to disseminate standards and procedures related to end-of-life care in Polish intensive care units.

The way young people see the mentally ill: a questionnaire study.

BACKGROUND: The stigmatizing of the mentally ill is quite common and has numerous social and economical consequences for these individuals. SUBJECTS AND METHODS: The aim of this paper was to examine young peoples' beliefs regarding the mentally disordered. The authors' questionnaire regarding the interviewees' age, gender, social background and their opinions on the mentally ill was conducted among a popular portal's users. RESULTS: 11900 people were questioned, including 71% women. 30% of the interviewees were under the age of 19, while 34% of them were between 19 and 24 years old and 36% were over 24. 39% of the interviewees stated they closely knew at least one mentally ill person. 44% of the questioned believed a lot of criminal offenders were mentally ill. 66% of interviewees would not mind sharing a flat with a mentally disordered person, 64% would agree to work with one. Those who personally knew a mentally disordered person were more inclined to share a flat or start a relationship with such an individual, than the rest of the interviewed (51% vs. 37% for flat sharing and 38% vs. 26% for starting a relationship, p<0.001). More questioned under the age of 19 believed that significant number of criminal offenders were mentally ill, than those over the age of 24 (50% vs. 37%, p<0.001). CONCLUSIONS: According to the acquired data, many young Poles believe that the mentally disordered are inclined to break the law and behave aggressively. These opinions seem to be related amongst others to age and gender, and they result in unwillingness to have relations with the mentally disordered.

Determinants of Alcohol Consumption among Medical Students: Results from POLLEK Cohort Study.

BACKGROUND: The use of alcohol is a serious public health concern all over the world, especially among young people, including students. Medical students are often exposed to higher levels of distress, which may lead to a higher prevalence of psychoactive substance use and psychiatric co-morbidities. Alcohol abuse can be one of the detrimental methods of coping with distress. The aim of this study was to assess the prevalence of alcohol use among medical students in Poland. METHODS: We analyzed data from the POLLEK cohort study on alcohol consumption and possible influencing factors. RESULTS: Among the 540 students included, 167 (30.9%) were hazardous drinkers (HAZ) according to the AUDIT test. The main identified risk factors of hazardous/harmful drinking were male gender and smoking cigarettes. CONCLUSIONS: Given the fairly widespread alcohol abuse among medical students, it is necessary to implement screening (and intervention in the next stage) programs in these groups.

Impact of Two Different Recruitment Procedures (Random vs. Volunteer Selection) on the Results of Seroepidemiological Study (SARS-CoV-2).

The proper recruitment of subjects for population-based epidemiological studies is critical to the external validity of the studies and, above all, to the sound and correct interpretation of the findings. Since 2020, the novel coronavirus SARS-CoV-2 pandemic has been a new factor that has been, additionally, hindering studies. Therefore, the aim of our study is to compare demographic, socio-economic, health-related characteristics and the frequency of SARS-CoV-2 infection occurrence among the randomly selected group and the group composed of volunteers. We compare two groups of participants from the cross-sectional study assessing the seroprevalence of SARS-CoV-2 coronavirus, which was conducted in autumn 2020, in three cities of the Silesian Voivodeship in Poland. The first group consisted of a randomly selected, nationally representative, age-stratified sample of subjects (1167 participants, "RG" group) and was recruited using personal invitation letters and postal addresses obtained from a national registry. The second group (4321 volunteers, "VG" group) included those who expressed their willingness to participate in response to an advertisement published in the media. Compared with RG subjects, volunteers were more often females, younger and professionally active, more often had a history of contact with a COVID-19 patient, post-contact nasopharyngeal swab, fewer comorbidities, as well as declared the occurrence of symptoms that might suggest infection with SARS-CoV-2. Additionally, in the VG group the percentage of positive IgG results and tuberculosis vaccination were higher. The findings of the study confirm that surveys limited to volunteers are biased. The presence of the bias may seriously affect and distort inference and make the generalizability of the results more than questionable. Although effective control over selection bias in surveys, including volunteers, is virtually impossible, its impact on the survey results is impossible to predict. However, whenever possible, such surveys could include a small component of a random sample to assess the presence and potential effects of selection bias.

Decreasing the Impact of Anxiety on Cancer Prevention through Online Intervention.

BACKGROUND: Low levels of public knowledge, incorrect beliefs, and anxiety are the most often mentioned factors that may negatively affect the implementation of preventive campaigns and timely diagnosis of cancer. Cancer is a major unresolved problem for global public health. As a result, many effective preventive measures need to be found and implemented. METHODS: For a duration of 18 months, readers of the Polish scientific Internet portal were invited to participate in the Polish On-line Randomized Intervention aimed at Neoplasm Avoidance (PORINA) study. Level of cancer-related anxiety was our main measure (self-declared on a simple five-point Likert scale) in this analysis. RESULTS: A total of 463 participants were qualified for the final analysis. Respondents with a positive family history of cancer (p < 0.001) declared the highest level of cancer-related anxiety, whereas lower levels were declared by those previously treated for cancer (p = 0.006). The conducted educational intervention reduced the declared level of cancer-related anxiety. CONCLUSIONS: The results of this study provide evidence that the use of web-based interventions aimed at increasing awareness could reduce cancer-related anxiety and may lead to more frequent consent to undergo some of the medical procedures used to diagnose or treat cancer.

[The review of prospective studies on mental health and the quality of life of physicians and medical students]. / Przeglad badan prospektywnych na temat stanu zdrowia psychicznego oraz jakosci zycia lekarzy i studentów medycyny.

Psychosocial determinants play a significant role in shaping mental health and the quality of life of workers, including physicians. The results of the presented review indicate that mental health problems of physicians are particularly manifested by chronic fatigue syndrome and burnout syndrome, and are related to chronic stress exposure at the workplace. Moreover, published data suggest that the most important mental health problems of medical students and young doctors include alcohol addiction and risky alcohol consumption, depression, and potential suicidal ideation. The studies on mental health and the quality of life of physicians, including their determinants, as presented in this paper, were mostly conducted on the basis of prospective observations that enable the tracking of changes over time. Med Pr. 2020;71(4):483-91.

The Reliability and Compatibility of the Paper and Electronic Versions of the POLLEK Cohort Study Questionnaire.

Background: Chronic fatigue, depression, burnout syndrome, and alcohol addiction have been identified as significant mental health problems in young medical doctors. Given the lack of prospective studies in this area in Poland, the POLski LEKarz (POLLEK) cohort study was created. The goal of the POLLEK study is to assess the quality of life and health status (including mental health) of medical students and young physicians. The aim of the presented paper was to assess the reliability and compatibility of paper and electronic versions of the POLLEK questionnaire. Methods: Between 1 October 2019 and 28 February 2020, all medical students (N = 638) of the first year in the Medical University of Silesia were invited to participate in a cross-sectional study. Three hundred and fifty-three students (55.3%) who accomplished both versions were included in the current analysis. Results: Values of Cronbach's alpha >0.7 proved both modes of delivery to have good internal consistency, except for the individual Alcohol Use Disorder Identification Test (AUDIT) domains and the Environmental domain of the WHOQOL-BREF (paper version). Similarly, interclass correlation coefficients equal to or greater than 0.9 denoted an excellent reproducibility. Conclusions: We documented very good accordance and reproducibility of POLLEK questionnaire (both paper and electronic versions). These findings legitimize the use of the questionnaire interchangeably.

Dermoscopy of Cutaneous Graft-Versus-Host-Disease in Patients After Allogeneic Hematopoietic Stem Cell Transplantation.

INTRODUCTION: Progress in the transplant procedure has resulted in a higher proportion of patients with long-term survival after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Cutaneous graft-versus-host disease (GvHD) occurs often among patients who have undergone allo-HSCT. Routine diagnosis of skin and mucosal lesions is based primarily on clinical evaluation and histopathologic confirmation of skin biopsies. However, biopsy is an invasive method and histopathologic analysis is time-consuming, often accompanied by a lack of clinical correlation. There is therefore an urgent need for non-invasive, reproducible in vivo imaging methods that could be used in patients with cutaneous GvHD-both in the setting of initial diagnosis and during follow-up.The aim of the study reported here was to determine the role of dermoscopic monitoring of skin lesions in allo-HSCT recipients with consecutive histopathologic support as a non-invasive, alternative method to diagnose GvHD. METHODS: Twenty patients were examined by dermoscopy upon the manifestation of skin changes in the course of GvHD. Consecutive skin biopsies for histopathologic analysis were obtained from the suspected skin locations determined during dermoscopy. RESULTS: Graft-versus-host disease was confirmed by histopathology in 19 of the 20 allo-HSCT recipients. Four patients developed symptoms of acute cutaneous GvHD (grade 1, n = 2; grade 2, n = 1; grade 3, n = 1), and 15 patients developed chronic cutaneous GvHD. The most frequent dermoscopic signs (irrespective of whether GvHD was chronic or acute) were vessels and scaling (both n = 14, 73.7%). Hyperpigmentation and white patchy areas were present in eight patients (42.1%). Fair to moderate levels of agreement were found between presence of melanophages in the skin sample and dermoscopic granularity (Cohen's Kappa [κ] = 0.39), scaling (κ = - 0.3) and vessels (κ = - 0.42). The finding of white patchy areas was inversely associated with lymphocytic infiltration (κ = - 0.55). CONCLUSION: The results of this study suggest that dermoscopy may be a useful tool for diagnosing cutaneous GvHD in allo-HSCT recipients. Combining the clinical picture with dermoscopic features may bring us closer to a faster and easier diagnosis of GvHD.

Parental Declaration of Adverse Event Following Immunization in a Cross-Sectional Study in Poland.

Vaccines are a well-known and effective preventive measure in communicable diseases. However, like any medical product, vaccines can cause some adverse effects. With increasing population awareness, the number of reported events related to vaccination has increased. Aim: The aim of the study was to assess the frequency and type of reported adverse events following childhood immunization (AEFI), and to recognize the determinant of their occurrence related with a socio-demographic situation, parental knowledge, and/or opinions on vaccinations. Material and Methods: The self-administrated questionnaire was distributed to a group of 3000 random parents or legal guardians living in the Silesian Voivodship (the southern part of Poland) in 2016. The response rate was eventually 41.3% from 1239 participants. Both, the number of children and the percentage of vaccinations given in the studied region, was representative for Poland as a whole. Results: Approximately one-third (32%) of surveyed parents declared the occurrence of AEFI in their children. The most frequently declared AEFIs were: redness, pain, swelling at the injection site (27%), and fever (24.9%). The frequency of reported AEFI was associated with a higher level of parental education and the number of vaccinations given. A negative attitude toward vaccination and the belief that vaccination is unsafe were associated with a higher number of reported AEFI. Conclusions: The results obtained confirmed that the number of declared mild and moderate AEFI is related to a lower parental educational level and is associated with a better experience as a consequence of a higher number of vaccinations given. Frequent AEFI reporters represent negative attitudes toward vaccinations. Further investigation with the exact surveillance system is needed to improve parental trust in vaccination safety.

Evaluation of the First Polish Web-Based Intervention Aimed at Improving Cancer Prevention (the PORINA Study).

The appropriate level of the society's health-oriented knowledge is essential for improving the effectiveness of actions to reduce the number of new cases and deaths caused by cancer. The aim of this study was to identify the role of web-based educational campaigns in the field of cancer prevention in Poland. From 14.05.2015 to 13.11.2016 readers of Polish scientific websites were invited to participate in the "PORINA" prospective interventional study. A total of 1118 volunteers (unrepresentative sample) were recruited and randomized (interventional and control groups). After applying the inclusion and exclusion criteria, 463 participants (41.4% of the recruited) qualified for the final analysis; 207 were allocated to the interventional and 256 to the control group. A specially designed internet platform, a self-reported questionnaire (validated during the study) and educational materials which were prepared by a physician specialized in clinical oncology were used. Assessments of participants' knowledge were based on the authors Cancer Knowledge Index (CKI). The number of subjects with an increase in CKI score was significantly higher for the interventional group with minor changes in the control (p < 0.001). The highest increase in CKI scores was obtained in the following demographic groups: females, younger participants, those living in smaller villages and also among the less educated. An overall impact of presented web-based educational intervention was moderate. However, the results obtained confirmed that well-organized intervention supported by oncologists may be useful in cancer prevention.
