Depression among adolescents and young adults with HIV affects both their wellbeing and clinical care outcomes. Integrated care models are needed. We hypothesized that the SEARCH-Youth intervention, a life-stage-based care model that improved viral suppression, would reduce depressive symptoms as compared to the standard of care. We conducted a mixed-methods study of youth with HIV aged 15–24 years in SEARCH-Youth, a cluster-randomized trial in rural Uganda and Kenya (NCT03848728). Depression was assessed cross-sectionally with the PHQ-9 screening tool and compared by arm using targeted minimum loss-based estimation. In-depth semi-structured interviews with young participants, family members, and providers were analyzed using a modified framework of select codes pertaining to depression. We surveyed 1,234 participants (median age 21 years, 80% female). Having any depressive symptoms was less common in the intervention arm (53%) compared to the control (73%), representing a 28% risk reduction (risk ratio: 0.72; CI: 0.59–0.89). Predictors of at least mild depression included pressure to have sex, physical threats, and recent major life events. Longitudinal qualitative research among 113 participants found that supportive counseling from providers helped patients build confidence and coping skills. Integrated models of care that address social threats, adverse life events, and social support can be used to reduce depression among adolescents and young adults with HIV.
Marek’s Disease Virus (MDV) Meq Oncoprotein Plays Distinct Roles in Tumor Incidence, Distribution, and Size

Published: February 2025

Marek’s disease (MD), characterized by the rapid onset of T-cell lymphomas in chickens, is caused by Mardivirus gallidalpha2, an oncogenic alphaherpesvirus commonly known as Marek’s disease virus (MDV). MDV encodes a bZIP protein, Meq, which contains a bZIP domain (basic DNA-binding and leucine zipper dimerization domain) at the amino terminus and a transcriptional regulatory domain at the carboxyl end. Meq can transform murine and chicken fibroblasts in vitro and is essential for tumor formation in chickens. Meq homodimerization and heterodimerization through its bZIP domain are involved in Meq-mediated transformation. However, the role of Meq DNA-binding and transcriptional regulatory domains in transformation has not been investigated. In this study, we constructed recombinant Md5 (very virulent MDV) viruses expressing chimeric Meq proteins generated by swapping the DNA-binding and transcriptional regulatory domains of Meq of Md5 and vaccine (CVI988/Rispens) strains. Our results show that these recombinant viruses, rMd5-Md5/CVI-Meq (Md5 DNA-binding domain and CVI transcriptional regulatory domain) and rMd5-CVI/Md5-Meq (CVI DNA-binding domain and Md5 transcriptional regulatory domain), replicated at levels similar to parental rMd5 in cell culture and chickens and could transmit efficiently among chickens. Interestingly, parental rMd5 and chimeric viruses exhibited distinct pathogenic phenotypes in chickens: rMd5 caused 100% mortality, a moderate level of tumor incidence in visceral organs and small visceral tumors; rMd5-Md5/CVI-Meq caused 100% mortality, a high level of tumor incidence in visceral organs, and very large visceral tumors; while rMd5-CVI/Md5-Meq caused an average of 37% mortality, rarely induced tumors in visceral organs, and the visceral tumors were small. In conclusion, our study suggests that the DNA-binding domain of Meq plays an essential role in transformation (tumor incidence), while the transcriptional regulatory domain of Meq influences the distribution and size of MDV-induced tumors.
The Key Importance of Screening Underprivileged People in Order to Achieve Global Hepatitis Virus Elimination Targets

Published: February 2025

Chronic hepatitis B (HBV), alongside hepatitis D virus (HDV) super-/co-infection and chronic hepatitis C (HCV), are major contributors to cirrhosis, end-stage liver disease, hepatocellular carcinoma (HCC), and liver-related mortality. Despite significant progress in antiviral treatments and HBV vaccination, viral hepatitis remains a global health burden. Vulnerable populations, such as those experiencing homelessness, migrants, and economically disadvantaged groups, are disproportionately impacted by these infections, often facing barriers to care and exclusion from traditional health systems. This leads to undiagnosed cases and ongoing transmission, undermining global efforts to eliminate HBV and HCV by 2030, as outlined by the World Health Organization (WHO). Recent studies highlight the importance of tailored interventions to address health inequalities. For instance, on-site community-based screening initiatives targeting marginalized groups have shown promise, achieving higher linkage to care rates without monetary incentives. These approaches not only enhance diagnosis but also facilitate integration into healthcare systems, addressing both public health and social disparities. This review underscores the need for targeted strategies to promote the early detection and management of HBV and HCV in underserved populations. Such efforts are critical to advancing the WHO’s elimination goals, improving health outcomes, and addressing the broader social determinants of health.

In the process of automating all business processes of an organization, there is an opportunity to implement digitalization of internal audit. Digitalization plays a huge role in modern audit, transforming control and analytical processes, thereby increasing the quality of the audit. At the same time, digitalization of the economy is accompanied
by an increase in the significance of cybersecurity risk. The authors of the article pay special attention to this aspect, suggesting that when conducting an internal audit, when assessing the risk of cybersecurity, determine the formula for an unacceptable (undesirable) event.
Prayer singing among the peoples of the world: time and eternity
Authors:   Herzen State Pedagogical University of Russia, Klujev A.S. ,   Leading Researcher, Russian Institute for the History of the Arts, Saint Petersburg, Russia
Published: February 2025

The article examines prayer singing among the peoples of the world. It is noted that
prayer singing is common among all peoples, but especially among those who profess
Hinduism, Buddhism and Christianity. The role of Christian prayer singing is emphasized
due to the fact that Christianity, unlike Hinduism and Buddhism, is based on the interpenetration
of man and God. It is emphasized that in Christianity the deepest interpenetration
of man and God is carried out within the framework of Orthodoxy, therefore
prayer singing in Orthodoxy is of paramount importance. The Ecumenical character of
Orthodoxy is stated, while explaining that today, due to the historical reasons for the transition of the administration of the Orthodox Church from the Orthodox Church of Constantinople to the Moscow Orthodox Church, Ecumenism has become a distinctive feature of Russian Orthodoxy.

Sự chi phối từ tâm thức văn hóa tổ chức đời sống tập thể cũng như những biến động của thời đại nửa sau thế kỉ XVIII đã tạo nên hệquả, tầm quan trọng và ý thức lo nghĩ, nhớ thương về gia đình ở con người trung đại, nhất là với kẻ tha hương. Vấn đề này được Nguyễn Đề thể hiện rõ qua hình tượng lữ khách trong thơ chữ Hán khi xét từ góc độ mối quan hệ với gia đình, người thân. Bằng phương pháp nghiên cứu thi pháp, so sánh kết hợp hướng nghiên cứu liên ngành, bài viết làm rõ các đặc điểm của hình tượng lữ khách qua cách ứng xử với gia đình, người thân trong hoàn cảnh xa cách, li biệt dựa trên những sáng tác thơ chữ Hán của Nguyễn Đề. Kết quả nghiên cứu cho thấy hình tượng lữ khách trong thơ luôn thường trực ý thức hướng về gia đình, nhớ đến người thân và được biểu hiện qua ba đặc điểm: nỗi khắc khoải, âu lo khi chưa tròn bổn phận với gia đình, tổ tiên; nỗi vấn vương, nghẹn ngào khi xa cách em Tố Như, con cháu và những mơ hồ, hoài nghi trong ý nghĩ hẹn ước tái ngộ cùng huynh đệ. Từ đó, người đọc có thể nhận ra được những góc khuất nội tâm, chiều sâu nhân văn và tài năng thơ ca của Nguyễn Đề.
Blind and Low-Vision Students as Surveyors of in/accessibility in Technology-Mediated Formal Education
Authors: Shaheen Natalie L.
Published: February 2025

K-12 institutions are slowly realizing (a) that many of the instructional technologies they use are inaccessible and (b) that technical debt oppresses blind and low-vision (BLV) students. Herein, I report the findings from a qualitative exploration of how BLV students differentiate between accessible and inaccessible technology-mediated education. The findings suggest that in/accessible technology-mediated education is an assemblage of learning, access labor, teachers, technologies, temporalities, and affectivities. I argue that to construct technology-mediated education that is equitable and accessible to BLV students K-12 institutions must do more than pay off their technical debt. I conclude by offering recommendations for how K-12 institutions could extend their accessibility work beyond technical debt repayment.

Policy transfer is the process of understanding policies, administration, institutions and ideas from other countries to be used in a policy. This study focuses on policy transfer in the JKP program, which is part of the National Social Security, in terms of form, approach and learning process. The method used in this study is descriptive qualitative which aims to provide an overview of the current conditions of JKP policy transfer. The study results show that the policy transfer in the JKP program can be implemented optimally even though the level of participation is still not proportional to the number of workers who are victims of layoffs. Productive-age beneficiaries also need to be given more attention so that they can contribute again to the world of work. Therefore, the government needs to develop JKP by conducting regular monitoring and evaluation so that it can reach a wider range of participants, see the level of re-employment and develop programs to target PKWT. This step is expected to provide more equitable and effective benefits for all workers who need the JKP program.

Peer Group Dynamics and Smoking Behavior: Investigating Actual Social Norms in Adolescence
Authors: Sultana Sadia
Published: February 2025

Background: Adolescent smoking is a significant public health concern, with peer group dynamics and social norms playing a central role in influencing smoking behaviors. Perceptions of peer smoking prevalence and approval (descriptive and injunctive norms) are known to impact adolescent smoking initiation, but the mechanisms underlying these relationships remain unclear. Objective: This study aims to investigate the role of perceived social norms, peer pressure, and social ties in adolescent smoking behavior, with a focus on the mediating and moderating effects of misperceptions and peer smoking prevalence. Methods: A mixed-methods approach was used, combining qualitative and quantitative research techniques. Initially, secondary data analysis was conducted to explore existing research on social norms and adolescent smoking. This was followed by three focus group discussions with Bangladeshi adolescents to gain insights into their perceptions of peer smoking behavior and social norms. A survey was then administered to gather quantitative data on adolescents' smoking behavior, peer group smoking prevalence, and perceptions of social norms. Results: The study found significant correlations between perceived descriptive norms (beliefs about peer smoking prevalence) and perceived injunctive norms (beliefs about peer approval of smoking) with smoking behavior. Additionally, peer pressure and misperceptions of peer smoking behavior were identified as mediators in the relationship between perceived norms and smoking initiation. Peer smoking prevalence and social ties to smokers were found to moderate the effects of perceived norms on smoking behavior. Conclusion: The study highlights the significant role of social norms and peer influences in adolescent smoking behavior. Correcting misperceptions about peer smoking prevalence, reducing peer pressure, and addressing social ties to smokers are essential components of effective smoking prevention programs.

Aim: The aim is to investigate the peculiarities of post-traumatic stress disorder (PTSD) in armed conflict participants and to substantiate the directions of their social and psychological rehabilitation.
Materials and Methods: The research involved 100 armed conflict participants of the russian-Ukrainian war of 2022-2024 (men aged 23 to 54). Research methods included bibliosemantic, medical and sociological (interviews, questionnaires), and statistical methods.
Results: It has been found that the majority of armed conflict participants (66%) have a high degree of PTSD manifestation, the main symptoms of which are headache (96.9 %); sleep disturbance (69.7%); depression (74.2%); increased fatigue (62.1%); stomach cramps (59.1%); constant anxiety (68.2%); “paranoid” phenomena (45.5%); constant feeling of fear (71.2%); lack of self-confidence (65.2%); aggression (51.5%); substance abuse (30.3%); sense of guilt (27.3%); signs of hallucinatory experiences (24.2%); rage attacks (15.2%). The majority of soldiers (45 %) avoid any talk about traumatic events and choose “avoidance” as a defense mechanism. The technology of social and psychological rehabilitation of armed conflict participants with PTSD manifestations has been substantiated, which has the aim, tasks, stages, methods, principles, and techniques.
Conclusions: It has been found that partnership and cooperation are key to implementing rehabilitation impact, which should involve the armed conflict participant himself in the recovery process. Individualization and consideration of each person’s adaptive capacities, as well as the participation of commanders, medical personnel, psychologists, and fellow soldiers, are important elements of successful rehabilitation.
Hydrogen sulphide and sulphide waters in the light of latest research reports
Authors: Ponikowska Irena , Adamczyk Przemysław , Placek Katarzyna
Published: February 2025

For over 100 years healing properties, therapeutic use and effect mechanism of sulphide and hydrogen sulphide waters have been researched. In recent time, especially during the pandemic, interest in sulphide waters has greatly increased. Many research papers have been published showing new, previously unknown, therapeutic effects and indications for use. In this article authors present new research results, which supplement and broaden current knowledge regarding sulphide and hydrogen sulphide waters. Proving an important physiological role of endogenous hydrogen sulphide (H₂S) effect as signaling gas was an exceptionally important discovery. In this aspect hydrogen sulphide is now classified among other, earlier known signaling gases – nitrous oxide (NO) and carbon monoxide (CO). H₂S is created within the organism in enzymatic and non-enzymatic process. It is synthesized in blood vessel endothelium, cerebral tissue, liver, pancreas and gastrointestinal tract. Modern laboratory technology allows determining blood H₂S level. This allows proving that in case of many diseases (such as diabetes, Parkinson’s disease, brain stroke or dementia) the concentration of H₂S in serum is decreased. This led to the concept of supplementing hydrogen sulphide contained in mineral waters. Aside of earlier known effects of hydrogen sulphide and sulphide waters, the following new ones have been found in recent time: antioxidant, anti-inflammatory, cardio-protective, neuroprotective, metabolic and endocrine. In recent decade many new research results have emerged, proving that hydrogen sulphide and sulphide waters can be used therapeutically in wider way than before.

ESG RATING AS A FINANCIAL RISK MANAGEMENT TOOL IN THE DIGITAL ECONOMY: CHALLENGES AND OPPORTUNITIES
Authors:   Financial University under the Government of the Russian Federation, Moscow, Russia, Pavlika Alena Yu.
Published: February 2025

Over the past two decades, there has been increased attention to and awareness of corporate environmental, social, and managerial responsibilities (ESG). The asset allocation process has changed accordingly to accommodate these ESG responsibilities, and it has been largely recognized that private and institutional investors are sensitive to ESG factors when mak-ing investment decisions. In addition to ESG factors, other key equity-related factors that inves-tors usually pay attention to are risk-adjusted indicators such as the Sharpe ratio (SR) and the Sortino index (SI), as well as tail risk indicators such as cost at risk (VaR) and expected loss (ES). In general, SR, SI, VaR, and ES can provide investors with guidance on market performance regarding the risk of the stocks being investigated. In this context, the following research ques-tion arises: are firms' indicators sensitive to ESG indicators? The purpose of this study is to answer this question. In particular, the SR, SI, VaR and ES indicators for a number of listed companies are calculated and evaluated. The list of stocks under consideration consists of do-mestic companies represented on the international market by rating agencies (primarily due to the breadth of coverage) of the Sustainalytics and S&P Global indices for the period from 2022 to 2024. Empirical results show that the effectiveness of the risk market does not depend properly on high or low ESG estimates.
IMPERFECT COMPETITION IN THE AGRO-INDUSTRIAL COMPLEX, ANTIMONOPOLY POLICY TOWARDS AGRO-INDUSTRIAL ASSOCIATIONS IN MODERN RUSSIA
Authors:   State University of Land Use Planning, Moscow, Russia, Butusova Yulia K.
Published: February 2025

This study analyzes the phenomenon of imperfect competition in the agro-in-dustrial complex (AIC) of the Russian Federation and assesses the effectiveness of antimonopoly policy in relation to agro-industrial associations. The dominance of large vertically integrated structures in the agricultural sector and related industries (processing, logistics, distribution) results in systemic asymmetry of the market, leading to price disproportions, limited access of small enterprises to resources and reduced innovation activity. Based on the analysis of data from the Federal Antimonopoly Service (FAS of Russia), Rosstat statistics and case studies of court proceedings (2015-2023), the authors identify key institutional and market barriers that impede the formation of a competitive environment. Particular attention is paid to the contradic-tions between the declared objectives of antimonopoly regulation (Article 10 of the Federal Law “On Protection of Competition”) and their practical implementation in the context of the specifics of the agro-industrial complex, including the lobbying influence of agricultural holdings and in-sufficient adaptation of legislation to the digitalization of value chains. The results of the study demonstrate that the current mechanisms for controlling the concentration of ownership and abuse of market power do not take into account the regional differentiation of agrifood markets, which reduces the effectiveness of sanctions. In conclusion, we propose a model of flexible anti-trust regulation that combines incentives for small business cooperation with stricter merger control in segments with critical concentration.

Successful implementation of educational tasks requires from the teacher not only deep subject knowledge and methodological skills, but also the formation of a wide range of professional and personal qualities. These include, in particular, communicative competence, the ability to reflect and improve oneself, willingness to innovate and cooperate, psychological and pedagogical competence, the ability to effectively manage the educational process in condi-tions of uncertainty and adapt to rapidly changing requirements. The absence or insufficient level of development of these qualities limits the teacher's ability to achieve educational goals, reduces the quality of education and negatively affects the psycho-emotional state of students.
