The pandemic state has a destructive effect on the human psyche and induces fear for one’s own health. By reducing the risk of severe COVID-19, vaccination may indirectly improve the mental state. This study aims to assess the effects of vaccination on respondents’ mental well-being, their attitudes towards adherence to government recommendations limiting viral transmission, and to identify factors that may influence the decision to get vaccinated. The survey took the form of the authors’ own, fully voluntary, anonymous, online questionnaire. Standardised psychometric tools were used in the survey: Generalised Anxiety Disorder Assessment (GAD-7) and Manchester Short Assessment of Quality of Life (MANSA). The survey involved 1696 respondents, the vast majority of whom were women, and were aged 18–29. The vaccination status was declared by 1677 respondents (98.9%), 430 (25.4%) of whom were vaccinated with at least one dose of vaccine, while 303 (17.9%) respondents were not only unvaccinated at all, and declared no intention to get vaccinated in the future. Fully vaccinated individuals were found to have lower levels of anxiety, higher MANSA scores and lower subjective anxiety about being infected with COVID-19 than those awaiting vaccination or those with an incomplete vaccination regimen (one dose). Those who are not willing to get vaccinated have the lowest sense of anxiety and fear of being infected and they have the lowest adherence to government recommendations limiting SARS-CoV-2 transmission. Conclusions: COVID-19 vaccination reduces the level of anxiety about being infected and anxiety due to COVID-19 disease in people from the immediate environment. Those who are not willing to get vaccinated have extreme attitudes that negate the pandemic as a whole, including the need for COVID-19 vaccination. Fully vaccinated individuals still adhere to the SARS-CoV-2 prevention policies in place.

The outbreak of the Russian–Ukrainian war contributed to the largest migration movement in the 21st century. As a result, over 3 million refugees, mainly women, children and the elderly, arrived in Poland in a short space of time. Despite the ongoing war, it is important to remember that the COVID-19 pandemic is still present in the world, and before the outbreak of the war, Ukraine was struggling with its fifth wave. Furthermore, Ukraine has one of the lowest vaccination rates in Europe, not exceeding 40%. It is, therefore, reasonable to suspect that the vast majority of migrants have not been vaccinated. This situation may pose a significant epidemiological risk. Therefore, it is necessary to implement appropriate steps to determine the vaccination status of refugees and to supplement the vaccination with both the core and booster doses. In response to these needs, the government of Poland, like many other countries, has made it possible to provide free COVID-19 vaccination to persons fleeing war. In the face of massive migration, the overriding priority should be to ensure adequate medical care for refugees, including free COVID-19 vaccinations. However, it seems that the lack of willingness to vaccinate among Ukrainians is also replicated on migration. It seems reasonable that appropriate steps should be taken to increase awareness and confidence in vaccination, which may ultimately translate into increased vaccination uptake. Analyzing previous experiences, it is advisable to consider that the first step should be to promote vaccination and remind refugees of the possibility of free COVID-19 vaccination. Additionally, refugees should be encouraged to be vaccinated during every contact with health care workers.

Vaccination is the most effective tool to combat the COVID-19 pandemic. However, it is ineffective without appropriate public acceptance. In Poland, 53% of the country’s population is vaccinated, which puts us in the last position among the EU countries. Therefore, this study aims to assess the main concerns regarding vaccination in the unvaccinated population of Poland. The study was based on an original questionnaire that was distributed online. There were three phases of the study: Phase 1—before the preventive vaccination plan, Phase 2—2 months after implementation of the programme, Phase 3—after 4 months when the immunisation rate in Poland was 42%. A total of 4459 individuals participated in the study. As many as 1943 participants were excluded from the analysis due to lack of consent (30 subjects) or COVID-19 vaccination (1913 subjects). Out of the remaining 2516 unvaccinated individuals, 463 were participants in the first phase of the study, 1137 in the second phase of the study, and 916 in the third phase. As the preventive vaccination plan in Poland continued, concerns about vaccine adverse events, safety and efficacy were raised. The only lower concern was that about the vaccine transportation rules. Moreover, as the vaccination programme continued, there was an increase in the percentage of individuals declaring their full reluctance towards vaccination against COVID-19. Conclusions: The Internet is the main source of knowledge about the COVID-19 vaccination, so it should be focused on during vaccination campaigns. The public is primarily concerned about adverse events of vaccines and the lack of appropriate tests of the products used. Therefore, it is advisable to popularise the current state of knowledge and promote reliable information concerning the COVID-19 vaccination.

INTRODUCTION.Malaria is caused by the Plasmodium spp. which are spread through Anopheles mosquitoes. Disease is not endemic in Poland currently but can be brought from other countries, mostly from Africa and Asia. The main sign of the disease is fever with shivers repeated periodically. There is highly effective chemoprophylaxis available and treatment, which should be given quickly. CASE REPORT. A 35-year-old man have worked monthly in Nigeria since two years. He was using Malarone chemoprophylaxis, but contrary to recommendations. Patient presented to a hospital after four days of having fever in a medium-serious state. He reported three similar incidents in the past. Physical examination revealed hepatomegaly, depressive state, oliguria and diarrhoea. Lab tests showed DIC with thrombocytopenia, renal injury, liver injury, hypoalbuminemia. ECG indicated myocardial ischemia. Malaria Rapid Test and blood smear confirmed Plasmodium falciparum infection with 9,9% parasitemia. When antimalarial treatment was given, patient condition improved, but after three days in hospital he got pneumonia as a complication of malariaantibiotic admission was committed. Moreover, quinine caused temporary deafness and serological tests revealed chronic HBV infection. After 23-days of hospitalisation the patient was discharged in a good condition. A month later patient went to follow-up and only mild anaemia was shown. CONCLUSIONS. This case shown that even such severe disease like malaria can be cured well without serious complications if patient will be diagnosed quickly. Moreover patient's experience and respecting symptoms improve prognosis. There also should be stronger emphasis on the role of chemoprophylaxis -patient did not use it properly, so it did not have to prevent development of malaria.

Objectives: The aim of this review is to summarize the most relevant scientific discoveries regarding SARS- CoV-2 virus infection, with the special emphasis put on its pathophysiology and way of treatment.Methods: In November 2020, the research articles have been collected and examined manually to pick the most relevant. In case of fresh topics, e.g. vaccines, we have performed searching using adequate keywords. Preliminary analysis was conducted on 200 manuscripts.Results: Among them 59 papers were out-of-scope, and thus were rejected from the further elaboration. Another 25 papers were rebuffed because they presented topics, that have been extensively described in the already included papers. Basing on the 29 papers we have estimated ratio of observed SARS-CoV-2 infection clinical manifestations and comorbidities among hospitalized patients. 12 papers let us evaluate frequencies of deviations within laboratory markers concentrations, as well as weighted average of the laboratory tests results.Conclusion: Due to the significant infectivity of the virus and its harmfulness towards organism further studies are required to find accurate way of the disease treatment and suspending its spreading.

Spinach and its preserves have beneficial effects on the organism, associated with its dietary changes, but also affect by containing biologically active substances which directly affects the body’s tissues. The studies cited in this article have proven many effects of this interesting and, as it finds out, often undervalued plant. Water is the largest part of the spinach composition, however, it also contains carbohydrates and protein and it is linked with a rich source of valuable and necessary substances like microelements and vitamins. Storage, as well as the condition in which the spinach grew, has a large impact on its composition. Factors forming good development of this plant are organic farming, adequate lighting and growing season. There are many studies which are linked with beneficial spinach influence on nervous system, osteoarticular system, digestive system and endocrine system. Trials carried out on rats often prove rightness of hypotheses about beneficial and pleiotropic property of the spinach. Effect of local acting of spinach on teeth was examined, and it can diminish teeth hypersensitivity as well as potassium nitrate. In the other studies concerning about osteoarticular system impact of delaying osteoporotic changes associated with menopause, as well as formation of degenerative changes in the knee joints in rats. Another proved attribute of spinach is its beneficial influence on obesity. Spinach extracts by inhibiting hunger hormones and stimulating satiety hormones secretion can increase satiety level in comparison to placebo.
