Opis:
Sea trials with parametric echosounder SES-2000 Compact needs precise information about sounded area of the seafloor. Because of narrow beam both in horizontal and vertical surface each change of antenna position have high influence for results and analyze of measured data. Vessel has to be equipped with a special device, such as multibeam echosounder, to obtain more information about seafloor sounding which is an addition for basic measurements units. Information about bottom topography, from where sounding pulse comes, may give many useful data necessary to correct analyze by echosounder user. There are also parameters such as roll, pitch and heave, which have to be complied. These variables have an influence for shape and echo level. The last parameter analyzed in this article is a difference between vessels heading and bearing. This information comes from heading sensor and GPS receiver.

Opis:
The main subject of the analysis is the question of conformity with Poland’s Constitution of the possibility of carrying out clinical trials on minors. The author concludes that the provisions of Article 31 of the proposed regulation of the European Parliament and of the Council on clinical trials on medicinal products for human use, and repealing Directive 2001/20/EC, providing for the possibility of conducting clinical trials on minors, which are not aimed to be delivered for health benefit of those persons, are inconsistent with Article 39 of the Constitution of the Republic of Poland.

Many governments, charitable organizations and NGOs are dedicated to helping the world’s poor but much of their effort is wasted. In the opinion of Banerjee and Duflo this effort is based on assumptions that are untested generalizations at best, and harmful misperceptions at worst. Because of this, they propose a new way to fight global poverty. The paper presents this way. It is based on randomized trials to reveal the multi-faceted and complex economic lives of the poor. Limitations of the new perspective are shown.

Opis:
In all kinds of ways the idea of judgement has fallen under suspicion in recent times, and opportunities to exercise it have become fewer. It has suffered from being confused with judgmentalism, and from the assumption that it amounts to little more than subjective whim or preference. In the public services of the UK, and especially in education, it has been steadily eliminated by micromanagement and the insistence on tightly specified criteria, for example for assessment, and centrally detailed curricular schemes of work. The growth of neoliberalism, in which judgement becomes replaced by choice, has contributed to these developments. I argue that while the use of judgement does not constitute judgmentalism it cannot be practised in a moral vacuum, and that the exercise of moral judgement is more ubiquitous in our daily lives than is generally acknowledged. Finally I argue that opportunities for judgement and interpretation work to give our lives meaning, and that understandings of the nature of education that are implied by prevalent models of educational research, especially Randomised Controlled Trials and the insistence that educational research should be focused on discovering ‘what works’, further marginalise judgement and the making and discovery of meaning.

Introduction. The occurrence of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has emerged as a global pandemic with huge death tolls. Coronavirus disease 2019 (COVID-19) may progress from minimal infection to serious respiratory failure mandating treatment for a continuum of developed disease condition. Aim. The purpose of this review is to summarize the findings related to epidemiology, clinical manifestations, modes of transmission, diagnosis and the treatment modalities (both experimental and repurposed) for COVID-19. Material and methods. Literature were searched using various search engines like PubMed, SCOPUS, EMBASE, J-Gate, Google Scholar to look for review articles, randomized controlled trial results, prospective studies and, retrospective studies done on COVID-19 for the purpose of this comprehensive review. Analysis of the literature. The transmission seems to be occurring through droplet, fomite and aerosols (rarely). Currently there is no specific/targeted vaccine available. Priority is highly placed to identify possible treatment approaches to circumvention this disease. Conclusion. Till we find a vaccine, we have to strategize to optimally use the existing evidence of the indirect effects of these various available drugs for therapy and maintain a strict protocol for prevention and we must use triage system to admit only those critically ill or having severe disease.

Opis:
Non-commercial clinical trials play an increasingly essential role for global health. Thanks to them a progress of knowledge in medical and health sciences is possible. Non-commercial clinical trials are conducted without the participation of pharmaceutical companies, mainly in order to evaluate the effectiveness and safety of drug products already used in the pharmaceutical market. These studies are usually initiated by researchers working at medical universities and they are conducted in clinical hospitals. The Pharmaceutical Law states that the data obtained in non-commercial clinical trials cannot be used for marketing purposes and for changes to existing marketing authorizations. Non-commercial studies are usually carried out with the use of already registered drug products, but used in different dosages, different patient groups (eg. pediatric) or in another application. Non-commercial research leads to the development of new treatments for rare diseases which are rarely in the interest of pharmaceutical companies. This approach allows to broaden the knowledge of medicines, find a new application or a more effective dose. In Poland, non-commercial clinical trials constitute ca. 2-5% of all registered research. In the Western European countries, this rate is much higher (20-25%). There are many difficulties in undertaking independent clinical research without support from the pharmaceutical industry. There is a need to support non-commercial clinical trials addressed to relevant questions about public health and clinical decisions. In Poland, more funding for non-commercial research is still needed. In February 2019, the Medical Research Agency was established as the institution responsible for the development in the field of medical and health sciences. It can be a significant step to support non-commercial clinical trials and consequently it may open access to advanced modern pharmacotherapies for patients or reduction in the cost of treatment of selected diseases.
Niekomercyjne badania kliniczne odbywają się bez udziału firm z sektora farmaceutycznego. Badania te są często inicjowane przez badaczy, będących pracownikami uczelni i prowadzone są w oparciu o szpitale kliniczne. Celem badania niekomercyjnego nie jest uzyskanie zysku w zakresie wytwarzania lub obrotu produktami leczniczymi. Badania niekomercyjne najczęściej prowadzone są z wykorzystaniem już zarejestrowanych produktów leczniczych, ale użytych w innym schemacie dawkowania lub w innym wskazaniu terapeutycznym. Badania niekomercyjne prowadzą do opracowywania nowych metod leczenia m.in. chorób rzadkich, w przypadku których podejmowanie nowych badań klinicznych rzadko spotyka się z zainteresowaniem firm farmaceutycznych. W krajach Unii Europejskiej około 20-25% nowo rejestrowanych badań klinicznych stanowią badania niekomercyjne. Tymczasem w Polsce wśród rejestrowanych co roku badań klinicznych zaledwie około 2-5% stanowią badania niekomercyjne. Powołana w lutym 2019 roku Agencja Badań Medycznych ma zapewnić źródło finansowania niekomercyjnych badań klinicznych, co powinno przełożyć się na opracowanie nowych metod farmakoterapii.

The main point of the legal opinion is the question of conformity with Poland’s Constitution of the proposal for regulation of the European Parliament and of the Council [COM (2012) 369 final]. In provides an in-depth analysis of matter presented (only in general terms) in the opinion dated 27 August 2012. The author claims that Article 30(1) of the proposed regulation should be declared to be partly (i.e. in relation to the scope of regulation) inconsistent with Article 39 of the Constitution. He points out that the Constitution establishes a prohibition against medical experimentation on the human subject (and this notion includes clinical trials referred to in the proposed regulation) without his personal and prior consent. No limitation of this right is allowed, except for when it collides with other “equivalent” constitutional values, especially the right to life protection (Article 38 of the Constitution) and the right to health protection (Article 68 of the Constitution).

Opis:
The pharmaceutical industry remains today a prominent high-technology sector of the economy,and consistently maintains its competitiveness on the world market at a very high level. Similarly to aircraft and spacecraft manufacturing and the electro-energy industry, pharmaceutical industry belongs to a group of innovative high-technology industries, which are based on scientific research results processed for industrial activities. The purpose of this study is to present and analyse global trends currently observed in the pharmaceutical industry in the world. In an era of increasing globalization, new prime movers of the development of the pharmaceutical industry are the countries from peripheralregions, mainly members of the BRICS group. For this reason, this article focuses on the emerging Asian and Latin American markets, next to the United States and countries of Western Europe. At the beginning of the twenty-first century, Brazil and China deemed the stimulation of the pharmaceutical industry one of the prime determinants of their future economic development. The following paper at first presents characteristics of the pharmaceutical industry products: innovative and generic medicines, medications available without prescription, biological agents, biosimilars and pharmaceutical substrates. Furthermore, the author specifies the properties and rates the dynamics of changes that are taking place in the global pharmaceutical market, while explaining the specifics of the relocation of the pharmaceutical industry. By comparing the number of publications in the field of pharmacy in selected countries of the world, the author confirmed the increasing importance of this industry on the global economy. In the last part of the article, the author presents the structure, number and distribution of clinical trials on a global scale. To illustrate the trends currently taking place in the development of the pharmaceutical industry, the author used raw statistical data in the field of pharmacology and literature on the subject.

A clinical trial is each trial conducted in humans to discover or confirm the clinical, pharmacological, including pharmacodynamic, effects of action of one or more investigational medicinal products, or to identify the adverse reactions to one or more investigational medicinal products, or to monitor absorption, distribution, metabolism and excretion of one or more investigational medicinal products, taking into consideration their safety and efficacy. It ought to be remembered that clinical trials may be conducted with the use of medicinal products. Clinical trials must be conducted in a way which is in line with the primary principle that clinical trial participants’ rights, safety, health, and welfare override the interest of science and society.

Opis:
Declamatio sub forma judicii can be found in the Graudenz Codex (1731–1740). It is an interlude that jokingly reports an animal trial. The interlude is a humorous treatment of the historical trials on animals that continued from the Middle Ages to the eighteenth century. Onthe one hand, such eighteenth-century discussions of animal trials continued the medieval tradition. This would confirm the diagnosis about the existence of the “long Middle Ages”, especially in Central and Eastern Europe, where the cultural trends could be somehow belated in comparison to those in the West. On the other hand, perhaps writing about animal trials in the eighteenth century was already a form of medievalism. High culture propagated anthropocentrism in its thinking about animals, while folk culture entailed anthropomorphism. In animal trials animals are treated as subjects to the same regulations as humans, which means that they were seen as very much similar to humans. The eighteenth-century interlude recreates this tradition, but it is a source of satirical laughter.

Opis:
The purpose of the opinion is not to examine thoroughly the proposal for a regulation but only to assess the legal basis for its issue, and to provide an analysis of those provisions of the proposal that may raise doubts about their conformity with the Constitution of the Republic of Poland. The main conclusions of the opinion relate to the lack of grounds for delegation by the Republic of Poland to the bodies of the European Union of the competence to regulate the issue of clinical trials on medicinal products for human use under primary law of the EU. Such delegation would infringe Article 90(1) of the Constitution. The author claims that the time limits specified in the proposal for regulation for action of the State make it impossible for Polish public authorities to implement obligations resulting from the preamble to the Constitution and their duties relating to protection of individual’s rights referred to in its Article 30.

Introduction and aim. Blue light is part of the natural light spectrum and plays a role in regulating the circadian rhythm. However, with the increasing use of electronic devices and energy-efficient lighting emitting high levels of artificial blue light, concerns are raised regarding its potential effect on human health. Blue-blocking filters have been developed and are advertised as a solution to be used in spectacles or intraocular lenses. This review aims to provide an in-depth analysis of the use of blue-blocking filters based on the results of clinical trials. Material and methods. This review included relevant original papers reporting on clinical trial results from PubMed, Science Direct, and Google Scholar databases using specified keywords. Analysis of the literature. Trials conducted with patients reveal mixed results, with some showing no significant changes in vision and reading abilities, while others indicating potential limitations such as reduced contrast vision. However, blue-blocking filters have demonstrated potential benefits in improving sleep quality and mood, particularly in patients with sleep disturbances or psychiatric disorders. The efficacy of blue-blocking filters in mitigating symptoms of digital eye strain remains inconclusive. Conclusion. Overall, this paper provides a comprehensive assessment of the benefits and limitations associated with the use of blue-blocking filters, highlighting the need for further investigation in certain areas.

Opis:
W pracy przedstawiono empiryczne porównanie ośmiu metod oceny efektów obiektowych z doświadczeń prowadzonych na wczesnych etapach hodowli. Materiał do badań stanowiły wyniki doświadczeń z pszenicą jarą, pszenicą ozimą i jęczmieniem jarym przeprowadzonych w Choryni, Kobierzycach, Polanowicach, Modzurowie oraz Nagradowicach. Powyższe linie oceniano w doświadczeniach jednopowtórzeniowych z wzorcami (stosowano od 1 do 5 odmian wzorcowych, w zależności od doświadczenia). Wyniki otrzymane dla poszczególnych metod porównywano w oparciu o różne kryteria. Jednym z nich jest kryterium równomierności rozkładu na polu doświadczalnym linii wybranych do dalszych badań (wybierano od 20% do 30% ogólnej liczby badanych linii). Drugie kryterium polegało na porównaniu sum kwadratów różnic między estymatorami efektów badanych linii otrzymanymi przy zastosowaniu różnych metod i estymatorami efektów tych samych linii otrzymanymi przy pomocy klasycznej analizy wariancji doświadczenia wielopowtórzeniowego. Wskazanie najlepszej metody estymacji efektów obiektowych jest trudne, ponieważ wybór metody najlepszej zależał od lokalnych warunków środowiska doświadczalnego w poszczególnych miejscowościach. Na uwagę zasługuje jednakże fakt, iż we wszystkich analizowanych doświad¬czeniach najgorszą okazała się tzw. metoda „nieprzekształconych wyników pomiarów”, czyli ta, w której nie poprawia się otrzymanych pomiarów, a do dalszych badań przyjmuje się ustaloną frakcję (20%–30%) najlepszych linii. Stosunkowo najskuteczniejszymi (w sensie zastosowanych kryteriów) okazały się metody eliminujące przestrzenne zależności między jednostkami doświad¬czalnymi (poletkami).
In the paper the empirical comparison of eight methods of estimation of treatment effects in one-replicate trials (with replicated standards) is reported. The data from experiments on spring wheat, spring barley and winter wheat performed at Choryń, Kobierzyce, Polanowice, Modzurów and Nagradowice form a basis for all considerations. There were from one to five standard varieties used in particular trials. Different criteria were used. The uniformity of distribution of chosen (the best) lines in experimental area was one of these criteria. Another one based on comparison of the estimates of treatment effects with the same effects obtained when classical analysis of variance in muti-replicated trials was applied. Selection of explicit best method of estimation of treatment effects is difficult (or even impossible) as the decisions on superiority of a particular method is dependent on local type of field variability. Nevertheless, it is to be mentioned than in all cases the worst method was the method of raw data. The best were methods eliminating spatial relationships between plots.
