Opis:
Phosphonates are the group of organophosphorus compounds, which are characterized by the presence of covalent bond(s) between carbon and phosphorus atom in their structure. Both; the natural and synthetic phosphonic compounds, are encountered in various ecosystems, however because of their wide range of applications, the latter ones are considerably more frequently discussed. Regarding the broad spectrum of biological activity, capability to chelate metal cations and environmental stability of direct carbon to phosphorus bond under physiological conditions, phosphonic compounds found a variety of applications e.g. as pesticides, drugs, anticorrosive agents, additives to surfactants and flame resistant (partially)polymers. Such massive use of phosphonates, together with mentioned environmental stability of those compounds, results in their common presence as xenobiotic environmental pollutants. Scientific efforts dedicated to recognising the fate and biodegradation of phosphonic compounds in the environment had begun in 80’s last century. Currently it is known that many microorganisms, mainly bacteria, but also fungi, are able to decompose the C-P bond. Interestingly however, the number of known species of fungi that are able to biodegrade and/or to bio-transform the phosphonates, is relatively low. It seems to be surprising, because especially the fungi are known from their impressive skills to adaptation to various nutritional conditions. Such a thesis may be supported by the fact that the process of biodegradation of phosphonates may occur via several pathways. Enzymes which are known to catalyse this process are phosphonoacetaldehyde hydrolase, phosphonoacetate hydrolase, phosphonopyruvate hydrolase and C-P lyase complex. This article briefly presents the issue of degradation pathways of phosphonates, and the role of phosphonate- degrading fungi.

2018 Report
Opis:
In December 2019, the European Food Safety Authority (EFSA), and the European Centre for Disease Prevention and Control (ECDC), published the yearly report on the trends and sources of zoonoses and zoonotic agents in the European Union (EU) in 2018. Campylobacteriosis was the most frequently reported zoonotic disease in the EU, with 246.571 laboratory confirmed cases (including 719 in Poland), which means the same number as in 2017. Poultry meat still appears to be the most important food-borne source of Campylobacter spp. Salmonellosis was the second most frequently recorded zoonosis with 91.857 confirmed human cases (9064 in Poland), which was similar as in the 2017 report. Fresh poultry meat and products thereof followed by fresh pig meat were reported as major sources of Salmonella spp. On the other hand, the prevalence of salmonellae in breeding hens, laying hens, broilers and fattening turkeys decreased, in recent years. VTEC infections in humans were the third, most often reported zoonotic disease in the EU, with a total of 8161 confirmed cases (5 in Poland), which was significantly more than in 2017 (6073 patients). Yersiniosis was diagnosed in 7204 people (170 in Poland), which means the increase as compared to 2017 (6823 cases). The number of cases of listeriosis in humans increased to 2549, including 128 in Poland and among them, in the EU, 229 patients died (56 in our country). The number of Q fever and Francisella tularensis infection cases were 789 and 300, respectively (0 and 16 Poland), whereas the number of Brucella spp. and Mycobacterium bovis infections was 358 and 170, respectively (no cases in Poland).

Opis:
As in previous years, the European Food Safety Authority (EFSA), and the European Centre for Disease Prevention and Control (ECDC), published Report on the monitoring of zoonoses and zoonotic agents in the European Union (EU), in 2019. Campylobacteriosis still remains the first, most reported zoonotic disease in humans, in the EU, with 220,682 laboratory confirmed cases, including 715 in Poland. This means, that the trend for confirmed human cases of this disease was stable during years 2015–2019. Poultry meat is probably the most important source of food-borne Campylobacter. Salmonellosis was the second, most commonly recorded zoonosis with 87,923 confirmed human cases (8,373 in Poland), which is was at the a slightly lower level when compared to 2018. Salmonella was identified mainly in fresh poultry meat and products thereof. VTEC infections in humans, with regard to frequency, were the third reported zoonosis in the EU, with a total of 7,775 confirmed infections (14 in Poland), which was less than in the previous year (8,161 cases). Yersiniosis was identified in 7,048 people (196 in Poland), which was slightly less as compared to the previous data (7,204 cases). The number of listeriosis cases moderately increased to 2,621, including 121 people in Poland. However, the mortality rate was high and in the EU 300 persons have died, including 54 in our country. On the other hand, Listeria monocytogenes rarely exceeded the EU food safety limits in ready-to-eat food. The number of Francisella tularensis infections and Q fever cases were 1,280 and 950, respectively. For the first time since 2014, Q fever was identified in Poland (4 cases). Then, in 2019, Brucella and Mycobacterium bovis or M. caprae infected people were identified as 310 and 147 (two and 0 in Poland), respectively. This article aims at the presentation of the Report findings.

Opis:
In November 2021, the European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC), published the recent report on the monitoring of zoonoses and zoonotic agents in the European Union (EU), in 2020. The number of cases was usually much lower than in 2019, mainly due to lack of the United Kingdom data (non-EU Member State since January 31, 2020). Campylobacteriosis was still the first most reported zoonotic disease in the EU with 120,946 laboratory confirmed cases, including 414 in Poland. Poultry meat is probably still the most important food-borne source of Campylobacter due to remained a high level of these bacteria. Salmonellosis was the second most commonly recorded zoonosis with 52,702 confirmed human cases (5,205 in Poland), and Salmonella was mainly identified in fresh poultry meat and products thereof. In 2020, yersiniosis was the third on the list of reported zoonoses in EU, with a total of 7,048 cases (87 in Poland). VTEC infections in humans were identified in 4,446 people in the EU (only three cases in Poland), whereas the number of listeriosis cases was 1,876, including 62 people in Poland. However, the mortality was still high, since 167 (almost 9%), patients have died. The number of Francisella tularensis infections and Q fever cases were 641 and 523, respectively, which were much lower than in the previous year. Brucella and Mycobacterium bovis or M. caprae infected people identified in 2020 were 128 and 88 (none in Poland), respectively.

Opis:
At the end of 2021, the European Medicines Agency (EMA), published the 11th report on sales of antimicrobial agents used in veterinary medicine in 31 European countries in years 2019 and 2020. A total of 5,577.8 tons were sold in 2020 for animal treatment, including 5,507.7 tons used for food production animals, which was 5.6% more as compared to 2019. In Poland, 856.7 tons were sold, making 15.4% of total European antimicrobials consumption. EMA has developed a unit of measurement to monitor antibiotic use and sales across Europe as mg/PCU, where PCU means Population Correction Unit, and takes into account the animal population as well as the estimated weight of each particular animal at the time of treatment with antibiotics. Differences of sales of various antimicrobial classes between the countries (mean is 89.0 mg/PCU) in Europe was observed, from 2.3 mg/PCU in Norway to 393.9 mg/PCU in Cyprus (187.9 mg/PCU in Poland). These values show that between 2020 and 2021 in Europe and in Poland antibiotics use has increased 5.9% and 1.9%, respectively The largest proportions of the sold antimicrobials were accounted for penicillins (31.1%; 27.7 mg/PCU), tetracyclines (26.7%; 23.8 mg/PCU), and sulfonamides (8.8%; 6.4 mg/PCU). For the antimicrobials classes from the list of critically important antibiotics with highest priority in human medicine, namely 3rd and 4th generation of cephalosporins, fluoroquinolones, other quinolones, and polymyxins, the sales for food-producing animals accounted for 0,2%, 2.6%, 0.2%, and 2.8%, of the total sales in the 31 countries in 2020, respectively. In Poland, the highest consumption of antimicrobials were noted for penicillins (61.1 mg/PCU), tetracyclines (45.3 mg/ PCU), and macrolides (24.8 mg/PCU). For the period 2011–2020, an overall decline in sales of 43.2% was observed, from 161.4 mg/PCU in 2011 to 91.6 mg/PCU in 2020. During this period, sales decreased by more than 5% in 19 countries, whereas in four others sales increased by more than 5%, including Poland, where a total increase from 126.3 mg/PCU in 2011 to 197.9 mg/PCU in 2020 was noted. This article presents EMA report with critical comments and remarks.

Opis:
Przedmiot badań: W artykule dokonano analizy obszarów badań podejmowanych przez naukowców publikujących swoje artykuły w części ekonomicznej czasopisma Studia Prawno-Ekonomiczne. Analizie poddano wszystkie numery czasopisma, które funkcjonuje ponad 50 lat. Cel badawczy: Celem głównym artykułu jest zidentyfikowanie obszarów badawczych prezentowanych w części ekonomicznej czasopisma Studia Prawno-Ekonomiczne. W artykule dokonano przyporządkowania zidentyfikowanych obszarów badawczych do trzech dyscyplin naukowych, tj. ekonomii, finansów oraz nauk o zarządzaniu. W artykule uwzględniono artykuły opublikowane w Studiach Prawno-Ekonomicznych w całym okresie funkcjonowania czasopisma, tj. w latach 1968–2019. 1 Metoda badawcza: Treści przedstawione w artykule sformułowano na podstawie studiów literaturowych oraz analizy 832 artykułów opublikowanych w Studiach Prawno-Ekonomicznych. Szeroka formuła czasopisma oraz dostęp do tak dużej bazy artykułów pozwoliły na prześledzenie, jak na przestrzeni ostatnich 50 lat zmieniała się „polska myśl ekonomiczna”. Wyniki: Wyniki badań wskazują, że naukowcy najczęściej publikowali w Studiach Prawno-Ekonomicznych artykuły dotyczące ekonomii. Począwszy od lat dziewięćdziesiątych coraz więcej publikacji dotyczy nauk o zarządzaniu oraz finansów. Obszary badawcze podejmowane przez naukowców zmieniają się w zależności od sytuacji gospodarczo-politycznej Polski, Europy czy świata. Wyniki badań wskazują, że na przestrzeni analizowanych lat nastąpiła dywersyfikacja wybieranych przez autorów obszarów badawczych we wszystkich trzech przywołanych w artykule dyscyplinach. Obszarem badawczym, który w ostatnich latach jest przedmiotem szczególnego zainteresowania naukowców publikujących swoje teksty w Studiach Prawno-Ekonomicznych, jest nadzór korporacyjny. Co ważne, obszar ten podejmowany jest przez naukowców reprezentujących zarówno ekonomię, finanse, jak i nauki o zarządzaniu.
Background: The article analyzes the research areas undertaken by scientists publishing their articles in the economic part of the journal Studies in Law and Economics. All issues of the journal, which have been published for over 50 years, have been analyzed. Research purpose: The main goal of the article is to identify research areas presented in the economic part of the journal Studies in Law and Economics. This article assigns the identified research areas to three scientific disciplines: economics, finance and the management sciences. This paper includes articles published in Studies in Law and Economics throughout the period of the journal’s operation, i.e. in the years 1968–2019. Methods: The content presented in the paper is based on literature studies and analysis of 832 articles published in Studies in Law and Economics. The broad scope of the journal and access to such a large database of articles allowed tracing how the “Polish economic thought” has changed over the past 50 years. Conclusions: Research results indicate that scientists most often published articles on economics in Studies in Law and Economics. Beginning in the nineties, more and more publications concern management and finance sciences. The research areas undertaken by scientists change depending on the economic and political situation of Poland, Europe, or the world. The research results indicate that over the analyzed years there has been a diversification of research areas selected by the authors in all three disciplines cited in the article. Corporate governance is a research area that has become of particular interest to authors publishing in Law and Economics in recent years. Importantly, corporate governance research has been undertaken by scientists representing economics, finance, and management sciences.

Opis:
The variety of the chemical forms of phosphorus compounds occurring in plant tissues, accompanied by the complexity of the chemical composition of plants as the analytical matrices, are the reasons why there is no one, the best answer, how those individual substances may be determined qualitatively and quantitatively. Interestingly, if the subject of determination is the total phosphorus content, the spectrum of effective methods and techniques seems to be impressive. However, in case of spectrophotometric measurements and classical variants of absorption (FAAS) or emission (ICP-AES/ ICP-OES) spectrometry techniques, it is necessary at first to isolate various phosphorus forms from the matrix, and then to mineralize them prior determination. The development of combined methods e.g. ETV-ICP- AES or HR-ETAAS, does allow the isolation of the phosphorus analyte and its detection in a kind of “one step” analytical procedure, directly in plant tissues. Similar benefits, while maintaining the sensitivity of determinations, are brought by the use of XRF, SIMS or nanoSIMS - more expensive techniques of imaging the presence of phosphorus in biological matrices. In turn, the application of nuclear magnetic resonance spectroscopy, especially the 31P NMR technique is thought to be the most universal approach. Using this technique and being aware of higher limit of detection, it is possible to determine various plant phosphorus compounds qualitatively and quantitatively, at the same time.

Opis:
Opieka zdrowotna jest niebywale istotnym, a jednocześnie bardzo trudnym elementem polityki społecznej państwa. Zarówno w Polsce, jak i w wielu innych krajach, kwestia źródeł i sposobu finansowania opieki zdrowotnej to ważny element efektywnej polityki państwa, a jednocześnie jeden z największych problemów społeczno-ekonomicznych. Jednostkami organizacyjnymi systemu finansowania opieki zdrowotnej w Polsce są przede wszystkim instytucje udzielające świadczeń zdrowotnych: Ministerstwo Zdrowia i Narodowy Fundusz Zdrowia. Źródłem finansowania polskiego systemu opieki zdrowotnej są: budżet państwa, ubezpieczenia zdrowotne (dobrowolne lub obowiązkowe) oraz środki własne pacjentów. W Polsce obowiązuje system obowiązkowego, powszechnego ubezpieczenia zdrowotnego.
Health care is an extremely important and at the same time very difficult element of the social policy of the state. Both in Poland and in many other countries, the issue of sources and ways of financing health care is an important element of effective state policy and at the same time one of the largest socio-economic problems. Organizational units of the health financing system in Poland are primarily health care institutions: the Ministry of Health and the National Health Fund. The source of funding for the Polish health care system is the state budget, health insurance (voluntary or compulsory) and patients’ own funds. In Poland, universal health insurance is compulsory.
