Exploring the reasons behind nurses' intentions to leave their hospital or profession: A cross-sectional survey.

Background: Multiple factors can fuel nurses' intention to leave their employing hospital or their profession. Job dissatisfaction and burnout are contributors to this decision. Sociodemographic and work context factors can also play a role in explaining nurses' intention to leave. Objective: To investigate the role of sociodemographic and work context factors, including job resources, job demands, job dissatisfaction, depersonalization, and emotional exhaustion, on nurses' intention to leave their hospital or their profession. Design: Multicentre cross-sectional study. Settings: Eight European hospitals, two per each country, including Belgium, the Netherlands, Italy, and Poland. Participants: From May 16 to September 30, 2022, we collected 1,350 complete responses from nurses working at the selected hospitals (13 % response rate). Methods: The intention to leave was assessed through two 5-Likert scale outcomes, agreeing with the intention to leave the profession and the intention to leave the hospital. Logistic regression models were used for statistical analysis. Results: At the multivariable analysis, a higher intention to leave the hospital was observed for: younger age, having served on the frontline against COVID-19, lack of quipment, living in the Netherlands, emotional exhaustion, dissatisfaction with work prospects, and dissatisfaction with the use of professional abilities. There was a higher intention to leave the profession for: younger age, living in the Netherlands, having work-related health problems, depersonalization, emotional exhaustion, low possibilities of professional development, dissatisfaction with work prospects, lack of use of professional abilities, overall ob issatisfaction, and dissatisfaction with salary. Nurses living in Italy expressed the lowest intention to leave. Conclusion: While confirming the role of job dissatisfaction and burnout, we found higher intention to leave for young nurses, nurses with work-related health problems, and caregivers during the COVID-19 pandemic. Dissatisfaction with work prospects, professional development, and salary also increased the intention to leave. We call for educators, managers, and policymakers to address these factors to retain at-risk nursing categories, implementing strategies to mitigate intentions to leave.

Prevalence and determinants of overweight or obesity among medical students over a 2-year observation.

Introduction: University students are a special population group characterized by changes in BMI values over the subsequent years of education, with an upward tendency to BMI. The presented study aims to evaluate the prevalence of overweight and obesity and their determinants in medical students during the 2-year follow-up observation. Materials and methods: We analyzed data collected from the first follow-up of the cohort study named "POLLEK" conducted among medical students at the Medical University of Silesia in Katowice. Students were followed at two points of time: in their inaugural year of studies (the academic year 2021/2022, T1, N = 427), and subsequently in their second year (the academic year 2022/2023, T2, N = 335). Results: In the initial year of evaluation, 371 individuals (86.9%) exhibited normal body weight, 47 (11.0%) were overweight, and 9 (2.1%) were classified as obese. Subsequent assessments during the second year revealed the following distribution: 277 students (84.2%) with normal body weight, 40 (12.2%) classified as overweight, and 12 (3.6%) identified as obese. In summary, regardless of the academic year, an increased risk of being overweight or obese was significantly associated with dissatisfaction with personal health, financial strain, and a diet abundant in animal products. Conclusion: The results of our study confirmed an increase in the prevalence of overweight or obesity among medical students during the 2-year follow-up observation. Significant determinants of overweight or obesity among medical students were: dissatisfaction with individual health status, male sex, financial deficiencies, and a diet abundant in meat consumption.

Varicella-Zoster Disease of the Central Nervous System in Immunocompetent Children: Case Series and a Scoping Review.

BACKGROUND: Varicella-Zoster Virus (VZV) is characterized by its ability to enter a dormant state within the body. When the wild or vaccine virus reactivates, it can lead to herpes zoster (HZ), which infrequently manifests as a neuroinfection. OBJECTIVES: The aim of the study was to analyze the clinical manifestations and outcomes associated with VZV reactivation in the CNS in immunocompetent children. METHODS: We searched medical databases for case reports using the keywords "zoster", "meningitis", "encephalitis", and "immunocompetent". The inclusion criteria were age below 18 years, any gender, race, and ethnicity, no features or history of immunodeficiency, and confirmation of VZV reactivation through the detection of VZV DNA in the CSF. Patients were categorized into two groups: children experiencing the reactivation of the wild virus and children with the vaccine strain virus. RESULTS: The cohort included six children hospitalized in our hospital and 49 children reported in the literature. In 37 (67%), a wild-type virus was detected, while in 18 (33%), an infection was caused by the vaccine strain. There were no differences in the clinical presentation between the two groups. A typical rash was observed in 32 (58%) children. Approximately 41 of the 55 children (75%) received antiviral treatment. Four patients experienced complications. CONCLUSIONS: Neither a history of VZV immunization nor the absence of a skin rash can definitively exclude VZV meningitis. It is important to note that any seemingly healthy child, regardless of recognized risk factors, could develop HZ meningitis.

Retaining Healing Hands: A Transnational Study on Job Retention Interventions for the Healthcare Workforce.

Healthcare organizations worldwide face challenges in retaining their healthcare workforce, with individual and organizational factors influencing their intentions to leave. This study conducted eight online co-creation workshops and four Delphi sessions to gain qualitative and in-depth insights into job retention interventions, involving healthcare workers, hospital managers, and policymakers. A thematic analysis was conducted, resulting in multiple interventions that were clustered in four pre-defined themes: professional and personal support, education, financial incentives, and regulatory measures. Professional and personal support interventions included regular interprofessional team meetings, leadership training programs, self-scheduling and sabbaticals, support for administrative and non-clinical work, and the provision of psychological counselling. Educational interventions encompassed facilitating development opportunities, periodic evaluations, onboarding, mentorship programs, and peer support groups. Financial incentives included the provision of competitive salaries, adequate infrastructure, extra benefits, transport possibilities, and permanent employment contracts. Regulatory measures addressed the need for complementary legislation across various levels, fixed healthcare worker-to-patient ratio, and instruments to monitor workload. To optimize retention strategies, healthcare organizations should tailor these interventions to address the unique factors influencing their workforce's intentions to leave within their specific context. The study concludes that combining personal and professional support, educational opportunities, financial incentives, and regulatory measures is necessary because there is no one-size-fits-all solution.

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.

Hospital medical care and the COVID-19 mortality in METEOR partner countries (the Netherlands, Belgium, Italy, And Poland).

OBJECTIVES: Healthcare systems in European countries, including METEOR partner countries, are faced with the aging population, an increase in costs for innovative technologies and medication, a shortage of health professionals, and inequality in access to healthcare. Presented paper aimed to recognize and compare the functioning of healthcare systems between METEOR partner countries and simultaneously check if the current epidemiological situation of COVID-19 has some relationship with the number of medical staff, yearly gross domestic product, or documented percentage of fully vaccinated people. MATERIAL AND METHODS: In the model of descriptive epidemiological study, available demographic, socioeconomic, and healthcare organizational data in the Netherlands, Belgium, Italy, and Poland were compared to the epidemiological situation of the COVID-19 pandemic (percentage of fully vaccinated people, incidence, and mortality) in all mentioned countries. RESULTS: Obtained data confirmed that the lowest number of physicians, as well as the life expectancy and gross domestic product per capita, is in Poland. Simultaneously, the lower number of medical staff and lower gross domestic product (GDP) correspond to higher mortality due to COVID-19. The percentage of fully vaccinated with the last dose of the primary series was also the lowest in Poland. CONCLUSIONS: Obtained results confirmed that higher mortality due to COVID-19 in METEOR participants' countries is related to a lower number of medical staff and weaker GDP. The worse situation was noted in Poland, a country with problems in the functioning healthcare system, including hospital care and a serious shortage of practicing medical staff. Int J Occup Med Environ Health. 2023;36(3):417-27.

Significance of Th17 and Treg in Treatment Efficacy and Outcome in Pediatric Acute Lymphoblastic Leukemia.

Acute lymphoblastic leukemia represents a malignant proliferation of lymphoid cells blocked at an early stage of cell differentiation. It is the most common cancer occurring in children. Despite favorable prognosis, the survival rate of patients with poor treatment response or relapse remains dismal. The interaction between leukemic cells and the tumor immune microenvironment is pivotal in mediating tumor progression. In this study we evaluated associations between Treg and Th17 lymphocytes and the clinical presentation of ALL pediatric patients to validate their value in monitoring treatment outcome. The peripheral blood and bone marrow aspirates from 35 pediatric patients with ALL and 48 healthy control subjects were selected for the experiment. We demonstrated the numbers of Th17 lymphocytes and Tregs were increased in the bone marrow of ALL patients at the moment of diagnosis compared to the healthy control group, with the latter significantly decreasing during the course of ALL treatment. Patients with lower Th17 were found to demonstrate higher risk of blasts prevalence in bone marrow at day 33. ALL patients with lower WBC demonstrated higher frequency of Tregs. In summary, we identified a significant role of Th17 and Treg lymphocytes in ALL of pediatric patients and their contribution to disease-related parameters.

General health and its relation to the quality of life and alcohol consumption in a Polish cohort of medical students - preliminary results of POLLEK survey.

Introduction: First-year students of medicine are at higher risk of stress related to the new environment and study overload. Such factors can play a role and have an impact on their quality of life and general health status which can cause possible problems with alcohol use. The aim of the study is to assess the relationship between mentioned factors in the Polish cohort of first-year medical students. Materials and methods: The quality of life has been assessed within the WHOQOL-BREF questionnaire, the general health status was assessed via GHQ28, and alcohol consumption was assessed the by AUDIT questionnaire. Due to the lack of signature informed consent and lack of data, 381 (72%) students out of 525 were included in the final analysis. Result: The majority of the 1-year students were females 68%; (n = 259) vs. 32% (n = 122) males. Half of the students had lowered risk of distress. However, females had a higher risk of having higher scores in GHQ-28 than males. In relation to the assessment of the quality of life, the students with a lower level of distress (<32 points in GHQ-28) had better results in each WHOQOL domain. There was no association between general health status and alcohol use. For the students who had possible problems with alcohol use the OR was 1.15 95% CI (0.73-1.80) and for students who were probably addicted OR was 1.07 95% CI (0.33-3.41). Conclusion: The total quality of life in first-year Polish medical students is relatively high; however, half of them suffer because of distress and around 30% have some alcohol problems. Females are more likely to have higher GHQ-28 scores than males.

Cations impact radical reaction dynamics in concentrated multicomponent aqueous solutions.

Ultraviolet (UV) photolysis of nitrite ions (NO2-) in aqueous solutions produces a suite of radicals, viz., NO·, O-, ·OH, and ·NO2. The O- and NO· radicals are initially formed from the dissociation of photoexcited NO2-. The O- radical undergoes reversible proton transfer with water to generate ·OH. Both ·OH and O- oxidize the NO2- to ·NO2 radicals. The reactions of ·OH occur at solution diffusion limits, which are influenced by the nature of the dissolved cations and anions. Here, we systematically varied the alkali metal cation, spanning the range from strongly to weakly hydrating ions, and measured the production of NO·, ·OH, and ·NO2 radicals during UV photolysis of alkaline nitrite solutions using electron paramagnetic resonance spectroscopy with nitromethane spin trapping. Comparing the data for the different alkali cations revealed that the nature of the cation had a significant effect on production of all three radical species. Radical production was inhibited in solutions with high charge density cations, e.g., lithium, and promoted in solutions containing low charge density cations, e.g., cesium. Through complementary investigations with multinuclear single pulse direct excitation nuclear magnetic resonance (NMR) spectroscopy and pulsed field gradient NMR diffusometry, cation-controlled solution structures and extent of NO2- solvation were determined to alter the initial yields of ·NO and ·OH radicals as well as alter the reactivity of NO2- toward ·OH, impacting the production of ·NO2. The implications of these results for the retrieval and processing of low-water, highly alkaline solutions that comprise legacy radioactive waste are discussed.

Trends in Fat Modifications Enabling Alternative Partially Hydrogenated Fat Products Proposed for Advanced Application.

The natural properties of oils and fats do not always allow for their direct use in industry (e.g., for food, cosmetics, and pharmaceuticals). Furthermore, such raw materials are often too expensive. Nowadays, the requirements for the quality and safety of fat products are increasing. For this reason, oils and fats are subjected to various modifications that make it possible to obtain a product with the desired characteristics and good quality that meets the needs of product buyers and technologists. The modification techniques of oils and fats change their physical (e.g., raise the melting point) and chemical properties (e.g., fatty acid composition). Conventional fat modification methods (hydrogenation, fractionation, and chemical interesterification) do not always meet the expectations of consumers, nutritionists, and technologists. In particular, Hydrogenation, while it allows us to obtain delicious products from the point of view of technology, is criticised for nutritional reasons. During the partial hydrogenation process, trans-isomers (TFA), dangerous for health, are formed. One of the modifications that meets current environmental requirements and trends in product safety and sustainable production is the enzymatic interesterification of fats. The unquestionable advantages of this process are the wide spectrum of possibilities for designing the product and its functional properties. After the interesterification process, the biologically active fatty acids in the fatty raw materials remain intact. However, this method is associated with high production costs. Oleogelation is a novel method of structuring liquid oils with small oil-gelling substances (even 1%). Based on the type of oleogelator, the methods of preparation can differ. Most oleogels of low molecular weight (waxes, monoglycerides, and sterols) and ethyl cellulose are prepared by dispersion in heated oil, while oleogels of high molecular weight require dehydration of the emulsion system or solvent exchange. This technique does not change the chemical composition of the oils, which allows them to keep their nutritional value. The properties of oleogels can be designed according to technological needs. Therefore, oleogelation is a future-proof solution that can reduce the consumption of TFA and saturated fatty acids while enriching the diet with unsaturated fatty acids. Oleogels can be named "fats of the future" as a new and healthy alternative for partially hydrogenated fats in foods.

COVID-19 in Pediatric Intensive Care Units in Poland, PAPITCO-19 Study (Polish Analysis of PICU Trends during COVID-19).

BACKGROUND: Children suffering from COVID-19 constitute about 10% of the entire population infected with the virus. In most of them, we observe asymptomatic or mild courses; however, about 1% of affected children require a stay in a paediatric intensive care unit (PICU) due to the course of the disease becoming severely life-threatening. The risk of respiratory failure, as with adults, is associated with the coexistence of concomitant diseases. The aim of our study was to analyse patients admitted to PICUs due to the severe course of their SARS-CoV-2 infection. We studied epidemiological and laboratory parameters, as well as the endpoint (survival or death). METHODS: A retrospective multi-centre study, the analysis covered all children with a confirmed diagnosis of SARS-CoV-2 virus infection who were admitted to PICUs in the period from November 2020 to August 2021. We studied epidemiological and laboratory parameters, as well as the endpoint (survival or death). RESULTS: The study analysed 45 patients (0.075% of all children hospitalised in Poland due to COVID-19 at that time). Mortality calculated in the entire study group was 40% (n = 18). Statistically significant differences between the compared groups (survived and died) concerned the parameters of the respiratory system. Lung Injury Score and the Paediatric Sequential Organ Failure Assessment were used. A significant correlation between disease severity and the patient's prognosis was shown by the liver function parameter AST (p = 0.028). During the analysis of patients requiring mechanical ventilation and assuming survival as the primary outcome, a significantly higher oxygen index on the first day of hospitalisation, lower pSOFA scores and lower AST levels (p: 0.007; 0.043; 0.020; 0.005; 0.039, respectively) were found. CONCLUSIONS: As with adults, children with comorbidities are most frequently at risk of severe SARS-CoV-2 infection. Increasing symptoms of respiratory failure, the need for mechanical ventilation and persistently high values of aspartate aminotransferase are indicators of poor prognosis.

The Incidence Proportion of SARS-CoV-2 Infections and the Percentage of Deaths among Infected Healthcare Workers in Poland.

(1) Background: The incidence proportion of SARS-CoV-2 infection among healthcare workers (HCWs) in Poland is not exactly known. This study aims to present secondary epidemiological data identifying the scale of the spread of novel coronavirus infection and the estimation of vaccination coverage in selected professional groups of HCWs in Poland. (2) Methods: The secondary epidemiological data included both the number of infections and infection fatality rate (IFR) in individual occupational groups, which occurred throughout the observation period (January 2021-July 2022), both in the country and in individual voivodeship (administrative area). (3) Results: The incidence proportion of SARS-CoV-2 infections among HCWs was 16.48%. The highest percentage of infected workers concerned laboratory scientists (21.62%) and paramedics (18%). The highest frequency of infections among HCWs occurred in the province of Zachodnio-Pomorskie (18.9%). Due to COVID-19, 558 healthcare workers died during the analysed period, mostly nurses (n = 236) and doctors (n = 200). The results regarding the vaccination coverage of HCWs against COVID-19 indicate the highest percentage of vaccinated were among doctors (83.63%) and the lowest among physiotherapists (38.2%). (4) Conclusions: In general, the percentage of infections was high in Poland during the pandemic (16.48%). Significant territorial differences were observed in the frequency of infections, deaths, and percentage of vaccinated workers in individual voivodeships.

The prevalence and determinants of SARS-CoV-2 infections among healthcare workers, results of a cross-sectional study in the Silesian Voivodeship.

OBJECTIVES: A significant proportion of healthcare workers (HCWs) had been infected with SARS-CoV-2, which complicated the organization of patient care during the COVID-19 pandemic. However, the exact scale of infection prevalence among the group of HCWs is not known, therefore this study aimed to assess the prevalence of SARS-CoV-2 infection among HCWs in the Silesian voivodeship, Poland, and to define its determinants. MATERIAL AND METHODS: The cross-sectional study was conducted in 2 multidisciplinary hospitals in the Silesian voivodeship during the period October 2021-February 2022. The standardized WHO questionnaire Surveillance protocol for SARS-CoV-2 infection among health workers was completed by 242 HCWs. To assess the prevalence of SARS-CoV-2 infection and its determinants, such as personal, occupational, and work environment-related conditions and preventive behaviors, the collected data were subjected to statistical analysis. For this purpose, descriptive and analytical statistics (significance of differences in χ2 test) were used. RESULTS: Almost half (42.6%) of subjects were infected with coronavirus, most frequently care assistants (57.1%) and paramedics (50%). People suffering from chronic diseases were infected significantly more often (p < 0.001). The majority of the infected HCWs declared previous contact with COVID-19 patients (56.3%). Unfortunately, 10.3% of respondents refused to be vaccinated against COVID-19, most often care assistants (38.1%) and nurses (10.6%). The determinants such as sex, age, occupation, place of work (ward), participation in occupational safety and health training, use of personal protective equipment (PPE), or preventive behaviors did not significantly affect the risk of infection (p > 0.05). CONCLUSIONS: Even though the PPE was used and the percentage of fully vaccinated HCWs against COVID-19 was high (89.7%), the frequency of SARS-CoV-2 infected HCWs remains high at 42.6% (95% CI: 40.7-44.5%). The main determinants of SARS-CoV-2 infection risk among HCWs were previous contact with infected individuals and the presence of chronic disease. Int J Occup Med Environ Health. 2023;36(2):201-13.

Situation of Pediatric Patients with Testicular Torsion in Times of COVID-19.

PURPOSE: To assess whether the COVID-19 pandemic had an influence on presentation of testicular torsion and/or increase in the frequency of orchiectomy. Patients and Methods. This retrospective study included boys under 18 years of age with testicular torsion divided in two groups: pre-COVID operated in 2019 vs. COVID-19 group from 2020. We compared demographic data as well as local and general symptoms. We analyzed additional tests, intraoperative findings, length of operation and hospitalization, and followup. Results. We analyzed the data collected from 44 patients (24 boys from first group vs. 20 boys from second group). The median age was 13.4 years vs. 14.5 years in the latter. The median time of symptoms duration was 6.5 hours and 8.5 hours, respectively. The main manifestation was testicular pain without additional signs. The results of the laboratory tests did not reflect local advancement. In the 2019 group, Doppler ultrasound showed absent blood flow in the affected testicle in 62% vs. 80% in 2020. The mean time from admission to surgery was virtually identical: 75 minutes in 2019 vs. 76 minutes in 2020. The mean duration of scrotal revision was similar in both groups. There was only one significant difference: the degree of twisting. In 2019, the mean was 360° vs. 540° in 2020. Incidence of orchiectomy also did not significantly vary between the analyzed time periods, with 21% during the pandemic and 35% during the pre-COVID-19 period. Conclusion. We did not observe an increase in the number of testicular torsion cases during the COVID-19 pandemic. Most importantly, the rates of orchiectomy did not significantly differ between the patients with testicular torsion presenting during the COVID-19 outbreak.

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.

Readiness for Telemedical Services in Patients With Cardiovascular Diseases: Cross-sectional Study.

BACKGROUND: Telemedicine solutions, especially in the face of epidemiological emergencies such as the COVID-19 pandemic, played an important role in the remote communication between patients and medical providers. However, the implementation of modern technologies should rely on patients' readiness toward new services to enable effective cooperation with the physician. Thus, successful application of patient-centric telehealth services requires an in-depth analysis of users' expectations. OBJECTIVE: This study aimed to evaluate factors determining readiness for using telehealth solutions among patients with cardiovascular diseases. METHODS: We conducted a cross-sectional study based on an investigator-designed, validated questionnaire that included 19 items (demographics, health status, medical history, previous health care experience, expected telehealth functionalities, and preferred remote communication methods). Multivariate logistic regression was applied to assess the relationship between readiness and their determinants. RESULTS: Of the 249 respondents, 83.9% (n=209) consented to the use of telemedicine to contact a cardiologist. The nonacceptance of using telemedicine was 2 times more frequent in rural dwellers (odds ratio [OR] 2.411, 95% CI 1.003-5.796) and patients without access to the internet (OR 2.432, 95% CI 1.022-5.786). In comparison to participants living in rural areas, city dwellers demonstrated a higher willingness to use telemedicine, including following solutions: issuing e-prescriptions (19/31, 61.3% vs 141/177, 79.7%; P=.02); alarming at the deterioration of health (18/31, 58.1% vs 135/177, 76.3%; P=.03); and arranging or canceling medical visits (16/31, 51.6% vs 126/176, 71.6%; P=.03). Contact by mobile phone was preferred by younger patients (OR 2.256, 95% CI 1.058-4.814), whereas older patients and individuals who had no previous difficulties in accessing physicians preferred landline phone communication. CONCLUSIONS: During a nonpandemic state, 83.9% of patients with cardiovascular diseases declared readiness to use telemedicine solutions.

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 risk of respiratory incidents in response to the increase of ozone concentration in the ambient air, in the Silesian Voivodeship, in 2016-2017.

INTRODUCTION: Due to the high level of urbanization and industrialization, Silesian Voivodeship remains a region with the poorest quality ambient air, especially in the winter season in which alarm levels are constantly being exceeded. However, in the summertime, there are observed short-term episodes of high ozone concentrations for which their impact on the population health is poorly documented. The aim of the study was to assess the risk of daily respiratory health problems related to an increased pollutants concentration typical for photochemical smog. MATERIAL AND METHODS: In the ecological type of study, secondary epidemiological data were used. They were obtained from the National Health Fund (NFZ) in Katowice and included the number of outpatient visits in primary health care and hospitalizations due to respiratory diseases (J00-J99) and selected acute respiratory incidents registered between 01/01/2016 and 31/08/2017 in the Silesian Voivodeship. RESULTS: In the summertime of both years (2016 and 2017), there were observed short-term episodes of photochemical smog in the study region. Obtained results show a significant increase in the risk of outpatient visits due to total respiratory diseases, and also due to acute pharyngitis, acute laryngotracheitis, bronchitis, and asthma in response to the increase in ozone concentration. Similarly, a significant increase in the risk of hospitalization for all respiratory diseases was found, however, it appeared with a delay of at least two to three weeks. In the case of hospitalization due to bronchitis statistically significant risk was observed 2-4 days after the increase in exposure. CONCLUSIONS: The occurrence of registered respiratory incidents was confirmed in response to the increase in ozone concentration, characteristic of the summertime in the Silesian Voivodeship.

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.
