RESUMO

Gastrointestinal cancers are characterized by high incidence and mortality. However, there are well-established methods of screening. The endoscopy exam provides the macroscopical image and enables harvesting the tissue samples for further histopathological diagnosis. The efficiency of endoscopies relies not only on proper patient preparation, but also on the skills of the personnel conducting the exam. In recent years, a number of reports concerning the application of artificial intelligence (AI) in medicine have arisen. Numerous studies aimed to assess the utility of deep learning/ neural network systems supporting endoscopies. In this review, we summarized the most recent reports and randomized clinical trials regarding the application of AI in screening and surveillance of gastrointestinal cancers among patients suffering from esophageal, gastric, and colorectal cancer, along with the advantages, limitations, and controversies of those novel solutions.

RESUMO

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and is one of the leading causes of cancer-related deaths worldwide. Despite advances in medicine, it is still a cancer with a very poor prognosis. Both imaging and liver biopsy still have important limitations, especially in very small nodules and those which show atypical imaging features. In recent years, liquid biopsy and molecular analysis of tumor breakdown products have become an attractive source of new biomarkers. Patients with liver and biliary malignancies, including hepatocellular carcinoma (HCC), may greatly benefit from ctDNA testing. These patients are often diagnosed at an advanced stage of the disease, and relapses are common. Molecular analysis may indicate the best cancer treatment tailored to particular patients with specific tumor DNA mutations. Liquid biopsy is a minimally invasive technique that facilitates the early detection of cancer. This review summarizes the knowledge of ctDNA in liquid biopsy as an indicator for early diagnosis and monitoring of hepatocellular cancer.

RESUMO

The introduction and development of genetic testing has caused the emergence of numerous dilemmas, which pertain to the performed tests, their results, and the influence they have on an individual person. To minimize potential doubts, it is crucial to ensure compliance with established procedures and to fulfill all test-associated formalities. In 2018, a report of the Polish Supreme Audit's Office (a governmental control agency) on the quality of genetic tests revealed that there is much to be done in the field of laboratory diagnostics in Poland. The inspection of six selected laboratories performing genetic tests identified shortcomings in terms of formalities accompanying the process of performing laboratory tests, keeping patient documentation and personal data protection. Although the observed shortcomings pertained to legal aspects of genetic tests, and not the quality of the tests themselves, the aforementioned may be detrimental to the individual person and the society (eg, lack of consent undermines the concept of biological material ownership), may cause legal liability to the laboratory personnel and even undermine public trust in genetic testing.

RESUMO

Despite strontium ranelate use in osteoporosis management being one of the promising concepts in disease treatment, there is no clear evidence that strontium organic compounds are more effective than inorganic ones. The aim of this study was to compare strontium chlorate and strontium ranelate influence on the mice bone microarchitecture. We investigated whether strontium chlorate (7.532 mmol/L) and strontium ranelate (7.78 mmol/L) solutions fed to healthy SWISS growing mice (n = 42) had an influence on the percent of bone volume (BV/TV), trabecular thickness (Tb.Th), number of trabeculae (Tb.N), and separation between each trabecula (Tb.Sp) in the chosen ROI (region of interest) in the distal metaphysis of the left femurs. The cortical bone surface was examined close to the ROI proximal scan. There was an increase in each examined parameter compared with the control group. There were no statistical differences between strontium ranelate and strontium chlorate parameters. Our study indicates that organic and inorganic strontium compounds similarly affect the bone microarchitecture and strength.

RESUMO

So far, the rate of HIV-positive people who do not know their sero-status is about 14% and the percentage is higher among transgender women (TGW). They represent one of the most vulnerable groups to infection. HIV self-testing (HIVST) may be a way to reduce transmission of the virus. The aim of this analysis and in-depth review was to collect available data on factors that may influence the use and dissemination of HIVST among TGW. This review was conducted in accordance with PRISMA guidelines for systematic reviews and meta-analyses. All data from 48 papers were used. From the available literature, HIVST is a convenient and preferred method of testing due to its high confidentiality and possibility of being performed at home. However, there are barriers that limit its use, including marginalization of transgender people, stigma by medical personnel, lack of acceptance of sexual partners, and even cultural standards. Therefore, there is a need for activities that promote and inform on the possibility of using HIVST as well as enable easier access to it.

RESUMO

BACKGROUND: The dynamic character of the COVID-19 pandemic and its social consequences caused several medical and societal issues and dilemmas. The aim of our qualitative research was to capture and analyze attitudes and beliefs of convalescents who experienced mild symptoms of COVID-19 in the first wave of the pandemic and decided to donate their plasma for therapeutic purposes. MATERIAL AND METHODS: The article presents results of qualitative research conducted on the basis of grounded theory (GT) methodology. Empirical material includes 10 in-depth interviews conducted with respondents who had mild or asymptomatic disease and, after recovery, voluntarily donated their plasma to the Regional Centre for Blood Donation and Blood Treatment (RCKiK). Data were collected in May and June 2020 in Poland. Qualitative analysis was focused on the experience of convalescents who entered the social role of a sick person in individual, social, and organizational dimensions. RESULTS: The social role of the patient in the narratives of convalescents was related to three stages: (1) initiation to the role, (2) staying in the COVID-19 patient role, and (3) leaving the role. Research results enabled the distinction of three basic descriptive categories ("ontological uncertainty", "the global and individual dimension", and "being sick in the disease-infected environment"), which became epistemological framework for a detailed description of the roles played by an individual COVID-19 patient during the pandemic. CONCLUSIONS: The disease, despite its mild course, generated a number of non-medical issues, and the entire process of being ill was burdened with institutional and emotional struggles. The experience of mild COVID-19 is significantly modified by disease institutionalization. These results may contribute to a better understanding of the psychosocial dimension of COVID-19 and convalescents' motivations for plasma donation.

RESUMO

BACKGROUND: Assessment of community pharmacies' quality of service is a very difficult task, resulting from the multiplicity and variety of provided services as well as patient-related factors (i.e. their health condition, expectations, education level or cultural and social background). Although proceedings of pharmaceutical professionals are to a great extend legally determined and described in various acts and regulations, work diligence should be one of the most characteristic traits of a professional pharmacy employee. Many publications addressing the quality of services provided by pharmaceutical employees focus on patient satisfaction, here the authors focused on more objective methods i.e. prescription analysis. OBJECTIVE: The main aim of the study was to assess whether post-inspection National Health Fund reports would constitute a reliable source of quality assessment of pharmaceutical services provided by community pharmacies. METHODS: The study is an in-depth quality and quantity analysis of 28 post-inspection quarterly reports conducted by the National Health Fund between 2013 and 2019. RESULTS: Vast majority of inspections ended in stating a variety of irregularities. CONCLUSIONS: The analysis of irregularities contained in the National Health Fund's post-inspection reports does not seem an appropriate indicator of assessing the quality of pharmaceutical services provided in community pharmacies, because of its targeted character. Inappropriate performance of professional duties by staff members is the main source of irregularities in the implementation of prescriptions for reimbursable medications. There is a need to improve staffs' professional competence and ultimately the quality of pharmaceutical services.

RESUMO

INTRODUCTION: In the European Union, the process of controlling currently used medical devices is carried out and determined by legal provisions. The law stipulates that each entity responsible for using medical equipment must confirm its safety with an appropriate certificate issued by a notifying body. In Poland, the entity responsible for keeping records as to the withdrawn and suspended certificates, is the Office for Registration of Medicinal Products, Medical Devices, and Biocidal Products (URPL). Certification is required for all medical devices prior to their introduction onto the market and during their use. PURPOSE: The article presents data concerning the number of medical devices that failed to meet the certification criteria. METHODS: The research method is an analysis of available subject literature and a report on withdrawn and suspended certificates of medical devices in Poland. RESULTS: In the years 2014-2020, the notified bodies withdrew and suspended 13,354 certificates for medical devices, of which 9792 certificates were withdrawn, 2852 suspended and one falsified. CONCLUSION: The suspension or withdrawal of a certificate for medical devices due to the inefficiency, obsolescence, imprecision, or safety of the devices is an action that improves the safety of patients. Such action reduces the number of medical damages and the obligation to pay compensation to those injured.

RESUMO

The aim of this work was to assess orthorectic behaviors among young people and to evaluate their attitudes towards caring for their health. The study was conducted in 2019 on a group of 538 respondents aged 16-35. After analysis, 65 questionnaires were eliminated from further research, and the assessment of orthorectic disorders was performed using a method based on the modified ORTO-15 questionnaire on a group of 473 respondents. A large percentage of them exhibited an increased risk of orthorectic behaviors (32.8), which was higher among women than men (34.7% and 28.2%, respectively). People with higher risks of orthorectic disorders significantly more often reduced their consumption of foods high in fats and sugars. Attitudes of people with orthorectic disorders towards health care proved neutral, with a tendency to be positive. Nutritional behaviors observed in the studied group show some irregularities, which indicates the need for preventive and educational measures aimed at increasing awareness of the role of proper nutrition among young people. The obtained results may be the basis for further research on ON symptoms. One of the major areas of future research would be to create a reliable diagnostic tool which would allow for distinguishing between orthorexia and overdiagnosis.

RESUMO

Vaccinations cause controversies for numerous reasons: medical, religious, and even personal. The following paper focuses on one more, underestimated conflict between individual autonomy and public health in regard to obligatory childhood vaccinations. Every medical intervention should be preceded by informed consent; however, informed consent in the case of obligatory vaccinations cannot be voluntary and valid. Moreover, asking parents to sign an informed consent form is paradoxical in a situation where not signing it will lead to legal consequences. Our paper tries to accentuate the issue of involuntariness and invalidity of informed consent in the case of obligatory vaccination and tries to propose a solution that acknowledges requirements for vaccinations and makes parents feel safer coming in and out of a vaccination visit.

RESUMO

Predatory magazines are created by unreliable publishers who, after collecting a fee, publish the submitted paper in the Open Access (OA) formula without providing substantive control. For the purpose of "encouraging" authors to submit their work, they often impersonate existing periodicals by using a similar-sounding title, a similar webpage, and copied names of editors of the editorial board. They also offer credits close in name to the Impact Factor. The purpose of such activity is to deceive authors and to earn money in an unfair manner. This contribution presents mechanisms used by such journals and includes suggestions for protection from the duplicity and the subsequent disappointment of publishing, often for an exorbitant fee.

RESUMO

OBJECTIVE: The aim of the article is a critical presentation of the typology of consents included in the European Convention on Bioethics and in other formal solutions concerning the gathering of genetic material in institutions called Biobanks. MATERIAL AND METHODS: Existing types of Acts of Consent are inaccurate in their scope and possess insufficient information regarding the gathering of genetic material (application, usage, processing) and their final (future and diverse) use. RESULTS: Lack of precise legal regulations on the broad future use of genetic material may result in various formal problems relating both to research participants as well as those commissioning the research. Ultimately, it may lead to various complications with the appropriate legal interpretation of consent and possible claims on behalf of the donors. CONCLUSIONS: The presented proposition of consent with a terminal premise is to be applied eventually to legal and formal aspects of the collecting of genetic material. It is a possible solution which would clarify the issue of informed consent, and may be implemented in the regulations of the Convention as well as constitute a self-contained legislative solution to this matter. For example, Polish law in its current form, without the ratification of the Bioethical Convention, allows the collecting of material for genetic testing for determination of the risk of genetic defects in common genetic material from people who are planning to have a child.

RESUMO

The article presents vaccination obligation in relation to the existing or newly enacted legislation. Mass vaccinations and a wave of criticism they cause, forces us to reflect on the limits of medical intervention in the human body and the boundaries granted to individual's freedom and autonomy. This problem is universal and exists mainly in countries without mandatory vaccinations. Analyzing recent years, it must be underlined that a process in some legislatures has been introduced to enforce various forms of vaccination coercion. Although, refusing vaccinations has been treated liberally, the last wave of epidemics in the United States and Europe forced the creation of a different approach. Gradually in the USA, a duty (not a 'coercion') of vaccination is being enforced. Occurring epidemics, (e.g. measles) and dangers resulting from them, force authorities to violate the principle of autonomy and restrict individuals' freedoms regarding their own body. The article presents legal solutions relating to vaccinations in the United States and Europe i.e. administrative decisions imposing vaccinations, solutions conditioning social existence and financial penalties for not complying with this obligation and proposes a solution based on financial liability that will balance out patients' autonomy and public security.

RESUMO

In 1955, Eugene Garfield (1925-1917) published a paper in Science where for the first time he advocated the necessity of introducing parameters to assess the quality of scientific journals. Underlying this necessity was an observation of a trend where the whole area of influence in academic publishing was dominated by a narrow group of large interdisciplinary research journals. For this reason, along with Irving H. Sher, they created the impact factor (IF), also called the Garfield impact factor, journal citation rate, journal influence, and journal impact factor. The concept of IF concerns a research discipline called bibliometrics, which uses mathematical and statistical methods to analyze scientific publications. Established by Garfield in 1963, the Science Citation Index, a record of scientific publications and citations therein, contributed directly to the increased importance of this method. Since the 1960s, the register of scientific publications has expanded and their evaluation by the IF has become a fundamental and universal measure of the journal's value. Contrary to the authors' intentions in the creation of the index (IF), it is often used to assess the quality of contributions, simultaneously assessing the authors' achievements or academic career and academic institutions' funding possibilities.

RESUMO

Dynamically changing social situation associated with migrations, increasing freedom rights, popularity of anti-vaccine movements and the resulting from that decrease in herd immunity, forces the medical society and the governments of various countries to reflect on the attitude toward vaccinations. Issues of freedoms and self-determination frequently do not accept any medical coercion in case of prophylactic vaccinations, however, recent waves of epidemics revealed that there is a necessity for undertaking strict legal actions to encourage vaccinations. After analyzing various legal approaches toward vaccinations we believe that personal coercion in case of vaccination refusal has too far reaching sanctions and propose the possibility of balancing the right to autonomy and the medical coercion. We postulate that vaccination refusal should be equivalent with covering frequently high medical costs in case of infection, The threat of financing medical treatment should influence the decision making process of those opposing vaccinations simultaneously respecting their rights not too get vaccinated.
