Exploring the Experience of Existential Anxiety During the COVID-19 Isolation Period in a Small Sample of Young Kosovar Adults

International literature has documented the mental health impact of the coronavirus 2019 pandemic on global communities. However, for this period, a significant lack of research exists on the human and psychological experiences of Albanian Kosovars. This study aimed to retrospectively explore a specific experience associated with the isolation period, that is, the Kosovar young adults’ experience of existential anxiety. The notion of isolation is significant for the Kosovars as their country is recently independent with some referencing its political isolation in the European context. The current study was conducted from March to June 2022; Stage 1 included a quantitative sampling of existential anxiety among 115 Albanian Kosovars through the Existential Anxiety Questionnaire (Weems et al., 2004). In Stage 2, five participants with high levels of existential anxiety partook in in-depth interviews. For the qualitative analysis, the Existential Phenomenological Research approach was adopted. Using Paul Tillich’s existential anxiety framework, results revealed that this study’s participants experienced great losses with the start of the lockdown as they were students who had to return to their families. It appears that a process of transformation occurred in light of the hardships that individuals experienced. Implications for mental health practitioners and researchers are offered.

Postoperative outcomes after splenectomy: a 20-year single-center experience in Colombia.

Splenectomy indications are well documented; however, several infectious complications and potentially life-threatening conditions could arise after splenectomy. We aim to describe a 20-year single-center experience of postoperative outcomes after splenectomy and perform a subgroup analysis according to approach and surgical setting with a 30-day, 90-day, and 1-year follow-up. A retrospective cohort study was conducted between 2003 and 2023. We included all patients aged 18 years and older who underwent splenectomy. A description of clinical and operative variables with infectious outcomes was performed. Subgroup analyses were performed between open or laparoscopic approach and surgical setting. A total of 134 patients were included. Female patients constituted 52.99% (n = 71) of cases, with a mean age of 51.01 ± 20.79 years. The most frequent surgical indication for splenectomy was trauma in 31.34% (n = 42), and a laparoscopic approach was indicated in 41.79% (n = 56). Overwhelming post-splenectomy syndrome (OPSI) was evidenced in 2.24% (n = 3) of the population. Surgical characteristics such as operative time, intraoperative blood loss, and intensive care requirement and unit length of stay were higher in open and trauma patients. Our data describe the demographic, clinical and operative characteristics of patients undergoing splenectomy in Colombia, providing a solid basis for future research. The results obtained on overwhelming postsplenectomy syndrome (OPSI) and postoperative complications are comparable with those reported in the international literature, reinforcing the validity of our findings. Further prospective studies in this population are needed to optimize management strategies and improve clinical outcomes, particularly in higher risk subgroups.

Neuroepithelial cyst causing homonymous hemianopia treated through surgical marsupialization under visual-evoked potentials: A case report

Background: Neuroepithelial cysts (NECs) are rare entities, occasionally causing neurological symptoms that can be overlooked. Case Description: A case of an occipital neuroepithelial cyst is discussed. The initial presentation consisted of mild homonymous hemianopia and gait impairment. Conservative management was suggested to start with, but at 6 months follow-up, the patient’s symptoms were worsening. Surgery was performed under general anesthetic and using visual-evoked potentials. The cyst was marsupialized and connected with subdural space, and a few samples were sent for histological analysis. The patient experienced immediate improvement in her symptoms, and the visual tests at follow-up confirmed the resolution of the previously documented hemianopia. Conclusion: NECs should be carefully assessed to rule out symptoms associated with mass effects. This case and others reported in the international literature show that occipital neuroepithelial cysts can benefit from surgical treatment with meticulous preoperative planning. The aid of neuromonitoring is crucial to identify anatomical variations and cortical functionality that are potentially distorted in the presence of these lesions.

Oral pathologies in anticancer therapy: a literature review

Anticancer therapy is associated with a wide range of systemic symptoms, including oral pathologies, such as dry mouth, mucositis, masticatory spasm, osteoradionecrosis, dental caries, opportunistic infections, dysphagia, hypogeusia, dysgeusia, and hyposalivation. Dental professionals are the most qualified experts in the diagnosis and treatment of oral pathologies, as well as their prevention and control in cancer patients receiving radiation therapy or chemotherapy. The aim of the review was to assess domestic and international literature on primary oral complications associated with anticancer therapy. The review also aimed to highlight the importance of dental care in improving the quality of life of these patients, as well as to provide practical guidelines for managing these complications. The search was performed using electronic databases PubMed, eLIBRARY.RU, and Google Scholar. The search yielded 55 literature sources, which were included in the review. Anticancer therapy may result in significant oral pathologies, including mucositis, infections, hyposalivation, changes in taste, and pain. These symptoms can affect various functions of the oral cavity and oropharynx, causing dry mouth and difficulties chewing and swallowing, which impairs nutrition. Moreover, they can affect speech, oral hygiene, denture treatment, and appearance, all of which can be detrimental to oral health, as well as social and emotional wellbeing. These side effects may also reduce compliance with anticancer therapy, affecting treatment outcomes, overall health, and therapy costs. When examining cancer patients, a dental professional must consider the prescribed therapy, as well as potential long-term complications similar to those in patients receiving bisphosphonates. As a result, a cancer patient will continue to receive the necessary treatment, and any new problems will be identified early.

The modality of historical thinking in the latest Greek primary school curriculum and the new challenges in history education

AbstractThis paper refers to the concept of ‘historical thinking’ as it appears in the three versions of the recent Greek History Curriculum for primary school. It is a comparative study of the discourse of the three versions of the recent history curriculum for primary school. The methodological approach of this study was founded on Critical Discourse Analysis. The main purpose of this paper is to explore the meaning and context of this term as presented in the three versions of the history curriculum and to compare the findings of the study with corresponding references in the international literature regarding the terms of ‘historical thinking’. This study demonstrated that this term is not the same in all three versions of the curriculum. In the first version of the curriculum the term ‘historical thinking’ is mentioned autonomously and we also separately identify the term ‘critical thinking’, while in the second and third versions a synthesis of the term is observed, which eventually becomes ‘critical historical thinking’. As a result of this observation, the use of the terms is critically and comparatively studied. The main conclusion is that the term ‘critical historical study’ refers much more to the development of general skills and competences with cognitive characteristics and much less to the critical understanding of the historical past. Furthermore, the conclusions of this study suggest a perspective for historical thinking in contemporary curricula with new challenges such as the relationship of historical education with artificial intelligence and children's representations.

SLR ABOUT THE COSTS OF PRIVATE BLOCKCHAIN TECHNOLOGY FOR BUSINESSES

Since the appearance of Bitcoin (2009), blockchain technology has been used in many fields. Companies use it for financial services, goods tracking, data authentication and secure storage, among other things, in order to make their operations more transparent and efficient. This technology has revolutionized the data management and transaction processing, but the associated costs are also significant and relevant to understand. The costs of blockchains vary and depend on the type of blockchain and how it is used. In this article, we examine the costs of using blockchain technology based on international literature, studies and reports with systematic literature review. In the results the range of possibilities offered by technology is presented, as well as the technology related cost types, and expenditures what companies have to deal with.

Is corporate reputation associated with voluntary cybersecurity risk reporting?

Purpose This study investigated the effect of voluntary cybersecurity risk reporting (VCRR) on corporate reputation. By examining the association between VCRR and corporate reputation, this study aims to provide exploratory evidence of how cybersecurity risk is sensitive to a company’s image and reputation. Design/methodology/approach An automated content analysis of VCRR by 95 Bombay Stock Exchange-listed companies was undertaken using Python code. Signaling and legitimacy theories were adopted to interpret the findings, establishing whether VCRR was related to corporate reputation. Findings The results confirm that VCRR improves the corporate reputation in the financial market. The results also confirm the signalling and legitimacy theory that a company can manage reputational risks through higher voluntary risk disclosure. Practical implications The corporation’s managers can gain insights from the study’s findings and proactively address cybersecurity risks through strategic disclosure and management practices. In addition, organizations can recognize that investors value transparency and establish a positive reputation for those who communicate openly. Social implications A significant association between VCRR and corporate reputation implies that such disclosures enhance trust and transparency in the business sector and induce security and accountability among investors engaging with the company. Originality/value To the best of the authors’ knowledge, this study is the first that empirically investigates this issue and adds to the international literature a new explanatory variable, corporate reputation, to explain VCRR practices.

More or Less Ice? Shipping in the Russian Arctic and the Role of Climate Change

Melting sea ice has often been presented as a primary driver for development of Arctic shipping, but what role has it played for policies to develop the Northern Sea Route? It may look paradoxical that Russia has embarked on an ambitious icebreaker construction program, given climate change. In Russia, there have been contradictory assessments of further climate developments in the Arctic. Representatives of the nuclear icebreaker fleet have argued that a new cooling period will soon occur, whereas Russian climate science is dominated by unidirectional climate change. Nevertheless, there is agreement that more icebreakers are needed, since shipping activity is expected to increase, and an extended navigation season is an indisputable goal. Nuances in Russian climate science do not seem to play any role in policy planning for Arctic shipping. Shipping through the Arctic emits less greenhouse gases than navigation on conventional southerly routes, which may be used as an argument in favor of the Northern Sea Route. It is doubtful, though, that this will change priorities of international shipping companies, especially as long as international shipping is not subject to emissions standards. Many other considerations will have precedence. Obviously, Russia’s war in Ukraine and the ensuing international tension is affecting trade patterns and investments in the Russian Arctic. In this situation climate change plays less of a role in the development of shipping in the Russian Arctic. But even before the war climate change was less important than often assumed in the international literature.

Waste management system: sanitary-epidemiological and environmental aspects

Introduction. Despite the positive trends in the field of industrial and consumer waste management, issues related to the legal regulation of activities to eliminate objects of accumulated damage to the environment and its relationship with activities to eliminate unauthorized landfills remain unresolved. A separate and important problematic aspect is the assignment of waste to a certain hazard class and their subsequent accounting and neutralization. The study aims to consider the established practice of using sanitary-epidemiological and environmental legislation in the management of industrial and consumer waste, including in assessing their toxicity. Materials and methods. The authors conducted the study using an information and analytical method for analyzing regulatory documentation and scientific publications from the databases Elibrary, Scopus, Web of Science, PubMed, Techexpert, Consultant, etc. They also compared the topical issues of assessing the toxicity of production and consumption waste and identified the specifics of the methodology for calculating the amount of damage as a result of unauthorized waste disposal. Results. It has been established that one of the optimal solutions in the issue of assessing the hazard class of waste may be to bring the criteria for their classification according to the degree of toxicity to uniformity, as well as the development of a single document carried out by institutions regardless of departmental subordination. Studies conducted to determine the amount of damage as a result of unauthorized disposal of production and consumption waste and to establish the hazard class of waste must comply with the requirements of uniformity of measurements and accreditation in the national system, respectively. To correctly calculate the amount of harm, you need to use the value of the mass of waste with the same hazard class. The availability of separate documents in sanitary-epidemiological and environmental legislation can significantly affect the calculation of the amount of harm due to various methods of determining the hazard class of waste, as well as the timeliness of identifying the long-term impact of waste on the environment and public health. Limitations. The study is limited to the analysis of law enforcement practice in the field of waste management, as well as the results of research in domestic and international literature. The analysis will allow researchers to consider non-obvious and controversial issues in the planning of activities. Conclusion. Updating documents on the establishment of the hazard class of waste should be carried out considering law enforcement practice. The absence of duality in compliance with the established requirements in both the field of environmental and sanitary-epidemiological legislation can be a guarantee of the reliability and truthfulness of research. This will allow you to make the right management decisions. Ethics. The study does not require the submission of the conclusion of the biomedical ethics committee.

“A bit of a cough, tired, not very resilient – is that already Long-COVID?” perceptions and experiences of GPs with Long-COVID in year three of the pandemic. a qualitative interview study in Austria

BackgroundLong-COVID is a new multisectoral healthcare challenge. This study aims at understanding experiences, knowledge, attitudes and (information) needs that GPs had and have in relation to Long-COVID and how these evolved since the beginning of the COVID-19 pandemic.MethodsThe study used an exploratory qualitative research design using semistructured interviews. A total of 30 semistructured interviews with GPs in different primary care settings (single practices, group practices, primary care centres) were conducted between February and July 2022. The data were analysed using qualitative thematic content analysis with the software Atlas.ti.ResultsThis is the first study that empirically investigated Long-COVID management by GPs in Austria during the third year of the pandemic. All GPs indicated having experience with Long-COVID. In cities, GPs tended to have slightly better networks with specialists. The GPs who already worked in teams tended to find the management of Long-COVID easier. The symptoms that the physicians described as Long-COVID symptoms corresponded to those described in the international literature, but it is unclear whether syndromes and symptomes such as Post-Exertional-Malaise, autonomic dysfunction such as postural tachycardia syndrome or Mast-Cell-Overactivation-Syndrom, and cognitive dysfunctions were also recognized and correctly classified since they were never mentioned. Most GPs reacted quickly by granting the needed sick leaves and by seeing and discussing with the patients often.The treatment of the patients is described as an enormous challenge and frustrating for patient and GP if the treatment does not yield to significantly improved health also due to the high costs for the patient.ConclusionLong-COVID will continue to preoccupy our health care systems for a long time to come, as new variants of COVID-19 will continue to produce new patients without adequate prevention strategies. Therefore, it is not a question of if but when good support for GPs and adequate care pathways for people with Long-COVID will be implemented. Specific contact points that are familiar with therapy-refractory postacute infection syndromes like the postacute COVID condition as a subgroup of Long-COVID are urgently needed.

Incidence and Risk Factors for Amputations in Persons with Diabetes Mellitus: A Retrospective Cohort Study.

The aim of this study was to identify and analyze the incidence rate of amputations and their risk factors in people with Diabetes Mellitus (DM) in two specialized outpatient clinics in Brazil. This is an epidemiological, retrospective cohort study using data collected from electronic health records of 281 adult diabetic patient types 1 or 2; attended in specialized outpatient service between 2015 and 2020. Statistical analyses were performed using the 2 sample t-test or Wilcoxon-Mann-Whitney test, for quantitative variables, and the Pearson's χ2 test or Fisher's exact test for categorical variables. The investigation of the risk factors for amputation was carried out through logistic regression. The study was approved by ethical committee. The sample mean age was 65.6 years (SD 13.05), predominating male gender n = 211 (75%), type 2 DM n = 223 (86.7%), with cardiovascular disease n = 143 (63.2%), and about 68.7% (n = 156) with peripheral arterial disease (PAD). Seventy-seven had lower limb amputation (LLA), with a rate incidence of 31.9% during five years. Logistic regression analysis showed the following associations with amputation: Diabetic peripheral neuropathy increased the rate of amputation by 3.6 times (OR = 3.631, 95% CI = 1.214-11.353; P = .022), and peripheral arterial disease increased by 10 times (OR = 10.631; 95% CI = 2.969-57.029; P = .001). The LLA in individuals with DM in two specialized outpatient services was higher compared to international literature; DPN and PAD were confirmed as risk factors for amputation, according to literature. This finding suggests that the study population faces an increased risk of amputation, highlighting the urgent need for targeted interventions and implementing robust preventive strategies to transform the current scenario and mitigate these severe outcomes. A comprehensive approach is essential to proactively address the underlying issues and reduce the prevalence and impact of amputations in Brazil.

Barriers to discharge: A retrospective study of factors associated with stays of longer than 2years in a French secure hospital unit.

Extended stays in specialist secure hospital units raise ethical concerns. While this topic has been investigated in various countries, there has been little research on it in France. We aimed to study the length of stay of patients in the Henri Colin unit, a secure hospital unit in the Paris area and test relationships between length of stay and sociodemographic, clinical and legal features. In this records-based retrospective study, we included all 60 inpatients on a census day just prior to the pandemic. We chose a 2-year threshold to define long stay status. Mean length of stay was just in the long-stay range (756.7days, SD 1071.2). Over a quarter (17, 28%) of the patients had been hospitalised for more than 2 years and 5 (8%) patients for more than 5 years. In multivariate analysis, legal status and need for seclusion during stay were significantly associated with long-stay status. These results are consistent with international literature, especially as they show the significant interplay between legal and medical aspects in the patients' care pathway. As the first such study in a specialist medium security hospital unit in France, this study adds to the international evidence on the complexities surrounding extended stays in secure units and underscores the importance of addressing both clinical and legal aspects in the treatment of patients with mental disorders in these settings.

Performance of Molasses Waste as a Cement Replacement to Study Concrete Compressive Strength

To reduce the negative environmental impact of cement production and preserve natural resources, an experimental investigation was conducted to study the performance of concrete specimens at different curing ages and to determine the compressive strength of these specimens by replacing cement with molasses. Experimentation was carried out on the concrete specimens at a temperature range of 25 °C to 30 °C; six specimens were cast for each replacement ratio, except for 0.75% wt. of cement (86.55 g) and 1% wt. of cement (113.6 g), where five samples were considered for each ratio. The average 28-day compressive strength of the conventional concrete specimens came out to be 29 MPa, but increased to 40 MPa with the addition of 0.25% wt. of cement molasses (28.85 g). It was observed that as the percentage of molasses waste in the concrete mix was further increased by replacing the cement, the compressive strength of the concrete specimens increased gradually and then significantly decreased. The findings shed light on the prospect of using molasses waste instead of cement in the concrete mix. Also, it is worth mentioning that about 30% of the cost–benefit was obtained with reference to that of conventional admixtures available in the market for the production of concrete. However, it is notable that a long-term durability study needs to be conducted before making it viable. This work not only addresses a sustainable and innovative method of waste management (SDG12), but also contributes to low carbon emissions (SDG13). The novelty of this work lies in the fact that no such kind of study has been conducted in Pakistan so far, in addition to the very limited international literature available, and, in particular, no evidence on the compressive strength results at higher molasses dosages, i.e., 1% wt. of cement (113.6 g) and 2% wt. of cement (230.8 g).

Myroides species, pathogenic spectrum and clinical microbiology sight in Mexican isolates.

Myroides is a bacterial genus of opportunistic bacteria responsible for diverse infections including in the skin and soft tissues, urinary tract, cardiovascular system, and bacteremia, although the incidence of its reported infections is low, it is increasing, likely due the use of better bacterial identification methods, but also perhaps due an increase in its prevalence. In addition, their pathogenic role is limited in terms of reporting their microbial physiology, so the present work provides information in this regard in addition to the information that is available in the international literature. To describe the microbiological and genetic characteristics of seven different Myroides spp. clinical strains and comment on their phylum, pathogenic and resistance characteristics. Seven Myroides spp., strains associated with infections were included from 1/January/2012 to 1/January/20 and identified by miniaturized biochemistry and MALDI-ToF. Susceptibility tests were performed according to CLSI recommendations by broth microdilution. Whole genome sequencing was performed for each strain and bioinformatics analysis were performed. Strains were identified at genus level by two methodologies. Our results revealed that likely four strains belong to the species Myroides odoratimimus, while the other two may be undescribed ones. Remarkably, all isolates harbored several genes encoding antibiotic resistance determinants for ß-lactams, aminoglycosides and glycopeptides and in concordance, presented high levels of resistance, against these antibiotics (AK and GN both 100%, ATM, CAZ and FEP 100%, e.g.); moreover, the presences of carbapenemases were evidenced by meropenem (mCIM) and imipenem (CARBA NP) degrading activity in six isolates and two strains possessed plasmids harboring mainly ribosomal RNA genes, tRNAs and genes encoding proteins with unknown functions. Our study increases the knowledge about the biology of this understudied genus and highlights the potential of Myroides to emerge as a broader cause of recalcitrant opportunistic infections.

A scoping review and bibliometric analysis of educational research on water literacy and water education

This paper presents a scoping review of the international academic research literature on water literacy and water education, including its implementation in both formal and non-formal education. The review was conducted through various analyses to examine global trends using bibliometric analysis. Metadata from eight databases (Web of Science (WoS), Scopus, Dimensions, Lens, PubMed, ScienceDirect, ERIC, and Google Scholar) were integrated. The analysis of documents involves examining publication numbers, authors involved, publisher sources, and origin of publications. The research literature is categorized into surveys and interventions in water education. Surveys focus on water literacy, educational measurement, and educational development including teacher education. Analysis of interventions in water education identified learning activities and programs, educational media types, and suggested topics. From the review a framework for incorporating water education in science education through community-based experiential learning is derived.

Vascular complications in TAVI procedures: assessment, management, and outcomes-a retrospective study

ObjectiveTranscatheter Aortic Valve Implantation (TAVI) has emerged as a pivotal therapeutic modality for aortic stenosis, predominantly in the elderly population. Despite its clinical success, the incidence and implications of vascular complications during TAVI remain a subject of critical concern. MethodsA retrospective analysis was conducted on 140 patients who experienced vascular complications during TAVI procedures from a total cohort of 1343 cases. Patient demographics, clinical profiles, and procedural characteristics were scrupulously examined. Vascular complications, both intraoperative and postoperative, were identified through various diagnostic modalities. Statistical analyses were employed to discern associations and significance levels. Comparative assessments with international literature were performed to gain broader insights. ResultsThe study unveiled an overall incidence of vascular complications at approximately 10.44%. Coronary Artery Disease (CAD)-p-value (0.013), choice of valve type-p-value (0.016), and access point-p-value (0.027) demonstrated significant correlations with these complications. Complication incidences in TAVI procedures included pseudoaneurysms (4.76%), arteriovenous fistulas (1.49%), hematomas (0.37%), dissections (2.24%), arterial perforations (0.15%), stenosis/occlusion (0.37%), and closure device failures (1.94%). Over 70% of complications at the valve entry point result from dissections and closure device failures, while the pigtail entry point is predominantly linked to over 70% of pseudoaneurysms. Extended hospitalization (7.84 ± SD 3.14) was observed for patients experiencing vascular complications, underlining the importance of vigilant postprocedural care. ConclusionThis study provides comprehensive insights into vascular complications during TAVI procedures, shedding light on their incidence, risk factors, clinical presentations, diagnostic methodologies, and management strategies.

What’s the risk? It depends. Entrepreneurs’ and employees’ perceptions of domestic city-level institutional risk

With a focus on entrepreneurs' decisions related to domestic location choices, this study draws from the international business institutional risk literature to evaluate city-level risk perceptions while accounting for individual-level political views. Specifically, we surveyed entrepreneurs and prospective employees in an effort to evaluate how important 1) safety risk, 2) political risk, and 3) social risk are when considering where to live, work, and start businesses. This process also included a comparison to ease of doing business, a previously studied driver of investment decisions. To identify low (and high) risk domestic investment locations, we had participants rate 25 large U.S. cities on the risk factors. Our findings indicate that entrepreneurs and prospective employees care about the city-level institutional risk factors. However, the focus and perceptions of entrepreneurs and prospective employees are greatly influenced by political views, perceptions do not always mirror objective data, and the two groups weight risk differently. The key insight of our study is that, in order to access and maintain valuable human capital, entrepreneurs should begin considering employees' perceptions related to city-level institutional risk. Importantly, these perceptions are biased by factors such as one's political views. Likewise, to attract business investment, city leaders should consider these risk perceptions.

Retrospective analysis in in situ ductal carcinoma; 11 years of experience

Objective: To describe our experience in the diagnosis, treatment and follow up of patients with ductal carcinoma in situ (DCIS). Materials and methods: 953 breast carcinomas treated in the Mastology service of the Department of Gynecology and Obstetrics of the Hospital Aleman of Buenos Aires, between January 2004 and December 2014, are retrospectively analyzed. 206 biopsies (BRQ 25-mammotome 151-core biopsy 30) of ductal carcinomas in situ were identified, resulting after definitive pathological evaluation in 172 (18%) pure ductal carcinomas in situ of the total of 953 patients analyzed. Results: 206 biopsies (BRQ 25-mammotome 151-core biopsy 30) of ductal carcinomas in situ were identified, resulting after definitive pathological evaluation in 172 (18%) pure ductal carcinomas in situ of the total of 953 patients analyzed. The imaging report in the total of the 206 patients showed microcalcifications in 80.1%. The diagnosis of carcinoma in situ was made in 181 (87%) patients by preoperative microinvasive procedures and in the remaining 25 (13%) patients by radiosurgical biopsy (BRQ). There was evidence of 18.8% underdiagnosis after microinvasive procedures. In our case series, 84.3% were GH3/GH2 while 15.7% were GH 1. When comparing the size of the surgical specimens and correlating it with the 34 cases of invasive and microinvasive carcinoma, it showed that 54.8% of invasion in those tumors greater than 30 mm, 50.4% in those that exceeded 21 mm and in no case in those less than 10 mm. 20% of multicentric lesions were associated with invasive tumor. Sentinel lymph node technique was performed in 23.8% patients in the first surgery, resulting negative in all cases. When evaluating radiation and hormonal treatment, radiotherapy was performed in 131 patients (85.6%) and hormonal treatment was performed in 75% of the patients. In the follow-up until December 2014, 11 relapses (5.23%) were recorded. Conclusion: Our results are consistent with the international indexed literature in reference to diagnosis, treatment and recurrence rate pure of DCIS.

Ethnopolitical Trends of Party Building in Kazakhstan and China

The role of political parties in multi-ethnic states is quite complex, as they should be focused not only on political governance at the level of the state as a whole, but also on promoting national unity in interethnic relations, forming tolerant cooperation and interaction between different ethnic groups. Aim. This article aims to take the operation and development of political parties in multi-ethnic countries such as Kazakhstan and China as examples to study the role of political parties and to study cases from the practice of their activities in maintaining national stability, promoting social harmony, and protecting the interests of small ethnic groups.Tasks. One of the tasks of political parties in multi-ethnic states is to integrate different social interests and ensure that all ethnic groups have a voice and are represented in the decision-making process at the national level.Methods. Comparative analysis is used to compare models of multi-ethnic governance in different countries or regions, and to analyze the role and effectiveness of different political parties in these models. This will help to understand the strengths and weaknesses of different governance models and identify best practices. It also analyzes the reasons for the successes and failures of different countries and political parties by analyzing their historical practices of multi-ethnic governance. This will help to understand how political parties have responded to ethnic conflicts and governance challenges throughout history.Results. The research paper pointed out that the policies developed and implemented by political parties in multicultural countries in support of the cultures of different ethnic groups, the protection and promotion of the languages, religions, traditions and cultural identities of different ethnic groups, comply with the UN standards and principles on these issues. However, as shown by the political and SWOT analysis of the statutory and program documents of the political parties in the countries studied, there are problems.Conclusion. Certainly, political parties are making efforts to ensure equal opportunities and access for all ethnic groups to the economy, education, employment and so on, in order to promote the creation of a fair and inclusive society, while ensuring the civil rights of minority ethnic groups, or as it is called in international legal literature “national minorities”.
