Examining the creation of synergy in community coalitions for smoke-free environments in Armenia and Georgia.

Community coalitions depend on their members to synergistically pool diverse resources, including knowledge and expertise, community connections and varied perspectives, to identify and implement strategies and make progress toward community health improvement. Several coalition theories suggest synergy is the key mechanism driving coalition effectiveness. The Community Coalition Action Theory (CCAT) asserts that synergy depends on how well coalitions engage their members and leverage their resources, which is influenced by coalition processes, member participation and satisfaction and benefits outweighing costs. The current study used mixed methods, including coalition member surveys (n = 83) and semi-structured interviews with leaders and members (n = 42), to examine the process of creating collaborative synergy in 14 community coalitions for smoke-free environments in Armenia and Georgia. Members, typically seven per coalition representing education, public health, health care and municipal administration sectors, spent an average of 16 hr/month on coalition-related work. Common benefits included making the community a better place to live and learning more about tobacco control. The greatest cost was attending meetings or events at inconvenient times. Members contributed various resources, including their connections and influence, skills and expertise and access to population groups and settings. Strong coalition processes, greater benefits and fewer costs of participation and satisfaction were correlated with leveraging of member resources, which in turn, was highly correlated with collaborative synergy. Consistent with CCAT, effective coalition processes created a positive climate where membership benefits outweighed costs, and members contributed their resources in a way that created collaborative synergy.

Challenges and Opportunities to Advance Adolescent Health Measurement in Armenia: Alignment Between Global Priority Indicators and National Policies, and Feasibility of Collecting Sexual, Reproductive, and Mental Health Indicators.

PURPOSE: To assess alignment of the Global Action for Measurement of Adolescent health (GAMA) draft adolescent health indicators with national policies and explore challenges and opportunities for collecting data on adolescent sexual, reproductive, and mental health in Armenia. METHODS: We reviewed Armenia's national laws, decrees, policies, strategies, and programs for content related to the draft indicators. We conducted three focus group discussions with government and nongovernmental stakeholders and youth representatives on the feasibility of collecting the draft indicators, and analyzed the discussion segments related to sexual, reproductive, and mental health indicators. RESULTS: The policy review included 22 documents. Armenia's national laws, policies, strategies, orders, and decrees mention a range of tracking and monitoring activities in adolescent health, and many draft GAMA indicators are already incorporated into national statistics and are collected in ongoing surveys. However, policies and strategies often lack specificity around how to measure and report indicators. Sexual, reproductive, and mental health indicators were particularly sensitive to collect due to Armenian cultural norms and expectations, especially for younger adolescents under the age of 15 years. DISCUSSION: Guidance should be developed to facilitate the formulation of relevant policies with well-defined indicators and complete tracking and reporting information. Data collection should be further harmonized within the overall health information flow to avoid data overlap. While sensitization work and interviewer training can help address some issues around collecting data on sexual, reproductive, and mental health, it may be necessary to adapt certain indicators to be culturally acceptable in Armenia, such as by limiting the age range to above 15 years for highly sensitive indicators.

The potential range of west Asian apple species Malus orientalis Uglitzk. under climate change.

The wild relatives of cultivated apples would be an ideal source of diversity for breeding new varieties, which could potentially grow in diverse habitats shaped by climate change. However, there is still a lack of knowledge about the potential distribution of these species. The aim of the presented work was the understand the impacts of climate change on the potential distribution and habitat fragmentation of Caucasian crab apple (Malus orientalis Uglitzk.) and the designation of areas of high interest according to climatic conditions. We used the MaxEnt models and Morphological-Spatial Analysis (MSPA) to evaluate the potential distribution, suitability changes, habitat fragmentation, and connectivity throughout the species range in Turkey, Armenia, Georgia, Russia, and Iran. The results revealed that the potentially suitable range of M. orientalis encompasses 858,877 km², 635,279 km² and 456,795 km² under the present, RCP4.5 and RCP8.5 scenario, respectively. The range fragmentation analysis demonstrated a notable shift in the edge/core ratio, which increased from 50.95% in the current scenario to even 67.70% in the future. The northern part of the range (Armenia, northern Georgia, southern Russia), as well as the central and western parts of Hyrcania will be a core of the species range with suitable habitats and a high connectivity between M. orientalis populations and could work as major refugia for the studied species. However, in the Zagros and central Turkey, the potential range will shrink due to the lack of suitable climatic conditions, and the edge/core ratio will grow. In the southern part of the range, a decline of M. orientalis habitats is expected due to changing climatic conditions. The future outlook suggests that the Hyrcanian forest and the Caucasus region could serve as important refuges for M. orientalis. This study helps to understand spatial changes in species' range in response to climate change and can help develop conservation strategies. This is all the more important given the species' potential use in future breeding programs aimed at enriching the gene pool of cultivated apple varieties.

Breast Cancer Awareness and Screening Perceptions of Women in Yerevan, Armenia.

Objectives: Breast cancer is the leading cause of female cancer mortality in Armenia. The government is considering covering breast cancer screening, but prevailing attitudes towards it are unknown. This cross-sectional study assessed Armenian women's awareness and perceptions of breast cancer screening. Methods: We administered a validated telephone survey to women ages 35-65 registered in Yerevan's polyclinic system between 2019-2021, assessing sociodemographic characteristics, breast cancer exposure and screening attitudes, using an adapted Champion's Health Belief Model Scale (CHBMS). We analyzed the association, unadjusted and adjusted, between sociodemographic characteristics, screening exposure, and CHBMS scores. Results: 170 women completed surveys. Most (82.9%) were aware of screening, 48.5% knew someone with breast cancer, but only 42.5% had undergone screening, predominantly without their physician's recommendation (63.2%). Despite elevated awareness, 76.2% had never discussed screening with their provider. Barriers included cost and mistreatment concerns. Education consistently predicted prior screening and most CHBMS scores. Conclusion: Armenian women are highly exposed to breast cancer, but knowledge and prior screening primarily emanate from non-physician sources. Results highlighted the influence of education, patient-provider relationships, and healthcare costs, underscoring the importance of multi-level interventions.

A case-control study on pre-, peri-, and neonatal risk factors associated with autism spectrum disorder among Armenian children.

We aimed to investigate the role of pre-, peri- and neonatal risk factors in the development of autism spectrum disorder (ASD) among Armenian children with the goal of detecting and addressing modifiable risk factors to reduce ASD incidence. For this purpose a retrospective case-control study using a random proportional sample of Armenian children with ASD to assess associations between various factors and ASD was conducted. The study was approved by the local ethical committee, and parental written consent was obtained. A total of 168 children with ASD and 329 controls were included in the analysis. Multivariable logistic regression analysis revealed that male gender, maternal weight gain, use of MgB6, self-reported stress during the pregnancy, pregnancy with complications, as well as use of labor-inducing drugs were associated with a significant increase in the odds of ASD, whereas Duphaston use during pregnancy, the longer interpregnancy interval and birth height were associated with decreased odds of ASD. These findings are pertinent as many identified factors may be preventable or modifiable, underscoring the importance of timely and appropriate public health strategies aimed at disease prevention in pregnant women to reduce ASD incidence.

Impact of COVID-19 on essential healthcare services at the primary healthcare level in Armenia: a qualitative study.

BACKGROUND: The COVID-19 pandemic has presented significant global healthcare challenges, particularly impacting the continuity of essential health services in low- and middle-income countries. This study investigates the impact of the COVID-19 pandemic on the utilization and provision of essential health services in Armenia. METHODS: We employed a conventional qualitative study design, conducting semi-structured in-depth interviews (n = 17) within public and private primary healthcare (PHC) facilities in Armenia in 2021. Our study participants encompassed physicians providing specialty services in PHC facilities (e.g. endocrinologists, gynecologists/obstetricians, and pediatricians), regular visitors to PHC facilities (e.g. adults with chronic diseases, parents of children), and policymakers. Thematic analysis was conducted, yielding five emergent categories: mobilization and organization of PHC services during COVID-19; PHC visits during COVID-19; worsening of chronic conditions due to the decline in PHC visits; problems with routine childhood vaccinations; and patient-provider communication challenges. RESULTS: The number of in-person visits to PHC facilities declined due to adaptations in service delivery, imposed lockdown measures, and the public's fear of visiting healthcare facilities. Maternal and child health services continued with no major disruptions. PHC providers deliberately limited the number of maternal and child visits to essential antenatal care, newborn screenings, and routine childhood immunizations. Still, children experienced some delays in vaccination administration. The pandemic resulted in a notable reduction in follow-up visits and monitoring of patients with chronic conditions, thereby exacerbating their chronic conditions. Phone calls were the primary method of patient-provider communication during the pandemic. CONCLUSIONS: The COVID-19 pandemic has had a profound impact on the delivery and utilization of essential healthcare services at PHC facilities, especially for those with chronic conditions who needed continuous care. Unified national-level guidance and technical capacity are needed to direct the provision of essential services at the PHC level, promote effective health communication, and implement digital platforms for the uninterrupted provision of essential care during public health emergencies.

Migraine headache and other risk factors associated with glaucoma among the adult population living in Armenia: a case-control study.

PURPOSE: This study aimed to assess the association between migraine headache and glaucoma among the adult population living in Armenia. METHODS: This case-control study recruited 145 cases with glaucoma and 250 controls without glaucoma and other ocular disorders except refractive error from Optomed Canada Diagnostic Eye Center in Armenia. A structured questionnaire contained questions on socio-demographics, family history of glaucoma and stroke, ocular health, smoking, migraine, and obstructive sleep apnea. The Migraine Screening Questionnaire assessed possible migraine and the Berlin Questionnaire measured obstructive sleep apnea. RESULTS: The mean ages of cases and controls were 63.3 (SD = 12.3) and 39.5 (SD = 13.5), respectively. Females comprised 62.8% of cases and 69.1% of controls. A total of 17.8% of cases and 19.0% of controls had possible migraine. In the adjusted analysis older age (OR 1.17; 95% CI 1.12; 1.23), average/lower than average socio-economic status (OR 5.27; 95% CI 1.30; 21.3), and family history of glaucoma (OR 4.25; 95% CI 1.51; 11.9) were associated with high-tension glaucoma. CONCLUSION: Timely case detection of glaucoma among those with average/low socio-economic status and those with family history of glaucoma could prevent further progression of the disease. Further studies to explore the relationship between migraine headache and specific types of glaucoma may be worthwhile.

A Survival Analysis of Patients with Recurrent Epithelial Ovarian Cancer Based on Relapse Type: A Multi-Institutional Retrospective Study in Armenia.

BACKGROUND: Annually, approximately 200 new ovarian cancer cases are diagnosed in Armenia, which is considered an upper-middle-income country. This study aimed to summarize the survival outcomes of patients with relapsed ovarian cancer in Armenia based on the type of recurrence, risk factors, and choice of systemic treatment. METHODS: This retrospective case-control study included 228 patients with relapsed ovarian cancer from three different institutions. RESULTS: The median age of the patients was 55. The median follow-up times from relapse and primary diagnosis were 21 and 48 months, respectively. The incidence of platinum-sensitive relapse was 81.6% (186), while platinum-resistant relapse was observed in only 18.4% (42) of patients. The median post-progression survival of the platinum-sensitive group compared to the platinum-resistant group was 54 vs. 25 months (p < 0.001), respectively, while the median survival after relapse was 25 vs. 13 months, respectively; three- and five-year post-progression survival rates in these groups were 31.2% vs. 23.8%, and 15.1% vs. 9.5%, respectively (p = 0.113). CONCLUSIONS: Overall, despite new therapeutic approaches, ovarian cancer continues to be one of the deadly malignant diseases affecting women, especially in developing countries with a lack of resources, where chemotherapy remains the primary available systemic treatment for the majority of patients. Low survival rates demonstrate the urgent need for more research focused on this group of patients with poor outcomes.

MANIFESTATION OF CREATIVITY AMONG MODERN MANAGERS AS A FACTOR IN PROMOTING PERSONAL MATURITY AND MENTAL HEALTH.

The purpose of this article is to investigate the manifestation of creativity levels and criteria, conditioned by the ratio of personal qualities, motivational orientation, and contributing and hindering factors. These elements are regarded as pivotal factors in ensuring mental health and socio-psychological maturity. The study involved 300 managers from the private and public sectors of the Republic of Armenia. The research contributes to the academic discourse by introducing novel correlations between scientific concepts of creativity, enriching the theoretical foundations of creativity and motivation, creativity and personal qualities, and creativity and its contributing and hindering factors. Findings suggest a high level of creativity among managers, characterized by fluency, flexibility, and originality. Notably, power and altruism emerge as significant motivational orientations within the manager's psychological profile. Moreover, modern managers do not perceive reward or competition as hindrances to creativity. Essential factors conducive to creativity include dominance, competition, reward, freedom of thought, and a willingness to take risks in decision-making. The proposed creativity research and development model holds promise for informing a scientific approach to the psychological selection and training of managers.

Examining local smoke-free coalitions in Armenia and Georgia: context and outcomes of a matched-pairs community-randomised controlled trial.

INTRODUCTION: Local coalitions can advance public health initiatives such as smoke-free air but have not been widely used or well-studied in low-income and middle-income countries. METHODS: We conducted a matched-pairs community-randomised controlled trial in 28 communities in Armenia and Georgia (N=14/country) in which we helped establish local coalitions in 2019 and provided training and technical assistance for coalition activity promoting smoke-free policy development and enforcement (2019-2021). Surveys of ~1450 households (Fall 2018, May-June 2022) were conducted to evaluate coalition impact on smoke-free policy support, smoke-free home adoption, secondhand smoke exposure (SHSe), and coalition awareness and activity exposure, using multivariable mixed modelling. RESULTS: Bivariate analyses indicated that, at follow-up versus baseline, both conditions reported greater smoke-free home rates (53.6% vs 38.5%) and fewer days of SHSe on average (~11 vs ~12 days), and that intervention versus control condition communities reported greater coalition awareness (24.3% vs 12.2%) and activity exposure (71.2% vs 64.5%). Multivariable modelling indicated that intervention (vs control) communities reported greater rates of complete smoke-free homes (adjusted Odds Ratio [aOR] 1.55, 95% confiedence interval [CI] 1.11 to 2.18, p=0.011) and coalition awareness (aOR 2.89, 95% CI 1.44 to 8.05, p=0.043) at follow-up. However, there were no intervention effects on policy support, SHSe or community-based activity exposure. CONCLUSIONS: Findings must be considered alongside several sociopolitical factors during the study, including national smoke-free policies implementation (Georgia, 2018; Armenia, 2022), these countries' participation in an international tobacco legislation initiative, the COVID-19 pandemic and regional/local war). The intervention effect on smoke-free homes is critical, as smoke-free policy implementation provides opportunities to accelerate smoke-free home adoption via local coalitions.

Deciphering the maternal ancestral lineage of Greek Cypriots, Armenian Cypriots and Maronite Cypriots.

Cyprus was conquered from several populations because of its special geographical location. In this study, 406 unrelated Cypriot samples were tested based on their mitochondrial DNA. In more detail, 185 were Greek Cypriots, 114 Armenian Cypriots and 107 Maronite Cypriots. This is the first time where the mitochondrial DNA of Greek Cypriots, Armenian Cypriots and Maronite Cypriots is compared with the aim of characterizing the maternal ancestry of Cypriots. The control region of the mtDNA is the most informative in terms of studying maternal ancestry and consists of three hypervariable regions (HVS-I, HVS-II, HVS-III). The hypervariable regions can provide important information regarding the maternal ancestor of the tested samples. The entire control region of the mtDNA was used to determine the mitotypes and subsequently the haplogroups of all the Cypriot DNA samples. Based on the aforementioned analyses, Greek Cypriots were found to be genetically closer to Armenian Cypriots, while Greek Cypriots and Armenian Cypriots showed moderate genetic differentiation with Maronite Cypriots. The most prevalent haplogroups among Cypriots were haplogroups H and U, while R0 is common but in different frequencies for Greek Cypriots, Armenian Cypriots and Maronite Cypriots. It is proposed that the maternal ancestor may have originated during the Neolithic period and/or the Bronze age.

Prevalence of hepatitis B virus infection among general population of Armenia in 2021 and factors associated with it: a cross-sectional study.

OBJECTIVES: This study sought to determine the prevalence and associated factors of hepatitis B virus (HBV) infection ever in life and chronic HBV infection in Armenia. DESIGN: A population-based cross-sectional seroprevalence study combined with a phone survey of tested individuals. SETTING: All administrative units of Armenia including 10 provinces and capital city Yerevan. PARTICIPANTS: The study frame was the general adult population of Armenia aged ≥18 years. PRIMARY AND SECONDARY OUTCOME MEASURES: The participants were tested for anti-HBV core antibodies (anti-HBc) and HBV surface antigen (HBsAg) using third-generation enzyme immunoassays. In case of HBsAg positivity, HBV DNA and hepatitis D virus (HDV) RNA PCR tests were performed. Risk factors of HBV infection ever in life (anti-HBc positivity) and chronic HBV infection (HBsAg positivity) were identified through fitting logistic regression models. RESULTS: The seroprevalence study included 3838 individuals 18 years and older. Of them, 90.7% (3476 individuals) responded to the phone survey. The prevalence of anti-HBc positivity was 14.1% (95% CI 13.1% to 15.2%) and HBsAg positivity 0.8% (95% CI 0.5% to 1.1%). The viral load was over 10 000 IU/mL for 7.9% of HBsAg-positive individuals. None of the participants was positive for HDV. Risk factors for HBsAg positivity included less than secondary education (aOR=6.44; 95% CI 2.2 to 19.1), current smoking (aOR=2.56; 95% CI 1.2 to 5.6), and chronic liver disease (aOR=8.44; 95% CI 3.0 to 23.7). In addition to these, risk factors for anti-HBc positivity included age (aOR=1.04; 95% CI 1.04 to 1.05), imprisonment ever in life (aOR=2.53; 95% CI 1.41 to 4.56), and poor knowledge on infectious diseases (aOR=1.32; 95% CI 1.05 to 1.67), while living in Yerevan (vs provinces) was protective (aOR=0.74; 95% CI 0.59 to 0.93). CONCLUSION: This study provided robust estimates of HBV markers among general population of Armenia. Its findings delineated the need to revise HBV testing and treatment strategies considering higher risk population groups, and improve population knowledge on HBV prevention.

Molecular monitoring of insecticide resistance in major disease vectors in Armenia.

BACKGROUND: Armenia is considered particularly vulnerable to life-threatening vector-borne diseases (VBDs) including malaria, West Nile virus disease and leishmaniasis. However, information relevant for the control of the vectors of these diseases, such as their insecticide resistance profile, is scarce. The present study was conducted to provide the first evidence on insecticide resistance mechanisms circulating in major mosquito and sand fly populations in Armenia. METHODS: Sampling sites were targeted based mainly on previous historical records of VBD occurrences in humans and vertebrate hosts. Initially, molecular species identification on the collected vector samples was performed. Subsequently, molecular diagnostic assays [polymerase chain reaction (PCR), Sanger sequencing, PCR-restriction fragment length polymorphism (RFLP), quantitative PCR (qPCR)] were performed to profile for major insecticide resistance mechanisms, i.e. target site insensitivity in voltage-gated sodium channel (vgsc) associated with pyrethroid resistance, acetylcholinesterase (ace-1) target site mutations linked to organophosphate (OP) and carbamate (CRB) resistance, chitin synthase (chs-1) target site mutations associated with diflubenzuron (DFB) resistance and gene amplification of carboxylesterases (CCEs) associated with resistance to the OP temephos. RESULTS: Anopheles mosquitoes were principally represented by Anopheles sacharovi, a well-known malaria vector in Armenia, which showed no signs of resistance mechanisms. Contrarily, the knockdown resistance (kdr) mutations V1016G and L1014F/C in the vgsc gene were detected in the arboviral mosquito vectors Aedes albopictus and Culex pipiens, respectively. The kdr mutation L1014S was also detected in the sand fly, vectors of leishmaniasis, Phlebotomus papatasi and P. tobbi, whereas no mutations were found in the remaining collected sand fly species, P. sergenti, P. perfiliewi and P. caucasicus. CONCLUSIONS: This is the first study to report on molecular mechanisms of insecticide resistance circulating in major mosquito and sand fly disease vectors in Armenia and highlights the need for the establishment of systematic resistance monitoring practices for the implementation of evidence-based control applications.

Evaluating consumer self-medication practices, pharmaceutical care services, and pharmacy selection: a quantitative study.

BACKGROUND: The primary objectives of this study were the evaluation of consumer self-medication practices, the assessment of pharmaceutical care provided by pharmacy employees, and the analysis of consumer satisfaction with such care. The research was also aimed at examining the main criteria that consumers consider important when selecting a pharmacy in Armenia. METHODS: The survey was based on an anonymous questionnaire and carried out between March 2020 and November 2021. It was aimed at providing a comprehensive assessment of pharmaceutical care services and consumer pharmacy choice by investigating two distinct groups: pharmacy consumers and pharmacy employees. RESULTS: The research reveals that many residents in Armenia engage in self-medication without consulting professional sources, which can lead to potential risks and result in dangerous consequences. This is partly due to a lack of trust in pharmacy employees, which is primarily due to their inability to provide adequate information and advice. This study highlights a significant need for improvement in the quality of service provided by pharmacy employees. Despite these challenges, the majority of consumers reported having a preferred pharmacy, and that employee knowledge is the most important criterion when choosing a pharmacy. CONCLUSIONS: Consumer distrust, in this context, is based on the incomplete knowledge or incompetency of pharmacy employees. Collective actions should be taken to improve the role of pharmacy employees and consequently improve the public trust in them, which can ensure better control of self-medication and reduce the instances of mistreatment.

Factors associated with delay or avoidance of medical care during the COVID-19 pandemic in Armenia: results from a nationwide survey.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has disrupted healthcare systems throughout the world. Many patients faced delays and cancellation of care due to scaled back services, mobility restrictions, and concerns related to the risk of infection. The present study aimed to assess the prevalence of and risk factors associated with the avoidance or delay of medical care due to COVID-19 in Armenia. METHODS: We conducted a cross-sectional telephone survey of 3,483 adults across Armenia. We used stratified two-stage cluster sampling to select the participants from different age groups proportionate to their size in the population. Logistic regression analysis assessed the association of risk factors with avoidance/delay of routine, urgent/emergency, and any medical care. RESULTS: The mean age of the sample was 49.5 (SD = 14.8), ranging from 18 to 90. About 9.9% of the respondents avoided/delayed any type of medical care; whereas 5.5% avoided/delayed urgent/emergency care and 6.6% routine care. In the adjusted analysis, female gender and higher monthly expenditures were associated with avoidance/delay of routine medical care. Factors associated with delay/avoidance of urgent/emergency care included female gender and higher perceived threat of COVID-19. Younger age, female gender, higher perceived threat and not being vaccinated against COVID-19 were associated with avoidance/delay of any medical care in the adjusted analysis. CONCLUSION: Since avoiding or delaying care might increase morbidity and mortality associated with conditions not related to COVID-19, identifying population groups that are more likely to avoid care is important. Targeting such groups with educational interventions focusing on the risks of using versus not using medical care in times of pandemic might be crucial. Ensuring the provision of in-home healthcare services for high-risk groups might help to address important medical care needs during the pandemic.

Nationwide Rapid Assessment of Avoidable Blindness (RAAB) in Armenia.

PURPOSE: This study aimed to estimate the prevalence and main causes of blindness and visual impairment in population aged 50 years and older in Armenia using Rapid Assessment of Avoidable Blindness (RAAB) methodology. METHODS: The study team randomly selected 50 clusters (each consisting of 50 people) from all 11 regions of Armenia. Data on participants' demographics, presenting visual acuity, pinhole visual acuity, principal cause of presenting visual acuity, spectacle coverage, uncorrected refractive error (URE), and presbyopia were collected using the RAAB survey form. Four teams of trained eye care professionals completed data collection in 2019. RESULTS: Overall, 2,258 people of 50 years and older participated in the study. The age- and gender- adjusted prevalence of bilateral blindness, severe and moderate visual impairment were 1.5% (95% CI: 1.0-2.1), 1.6% (95% CI: 1.0-2.2) and 6.6% (95% CI: 5.5-7.7), respectively.The main causes of blindness were cataract (43.9%) and glaucoma (17.1%). About 54.6% and 35.3% of participants had URE and uncorrected presbyopia, respectively. The prevalence of bilateral blindness and functional low vision increased with age and was the highest in participants 80 years and older. CONCLUSION: The rate of bilateral blindness was comparable with findings from countries that share similar background and confirmed that untreated cataract was the main cause of blindness. Given that cataract blindness is avoidable, strategies should be developed aiming to further increase the volume and quality of cataract care in Armenia.

Trends in pediatric CNS tumors in Armenia: a multicenter retrospective study.

PURPOSE: Central nervous system (CNS) tumors are the most common solid malignancies in children worldwide, including in Armenia. The current study aims to analyze epidemiological data, treatment, and outcomes of children and young adults (≤25 years) with CNS tumors in Armenia during the last 26 years. METHODS: We collected data from pediatric and young adult patients treated in selected sites in Armenia from 1st January 1995 to 31st December 2020. Incidence by sex, age at diagnosis, time from first complaints to diagnosis, histopathology results, treatment strategies, complications, and overall survival (OS) rates were calculated. RESULTS: The multicenter data analysis revealed 149 patients with diagnosed primary CNS tumors over 26 years. Among them, 84 (56.4%) were male. The median age at diagnosis was 7 years (range, 3 months to 25 years), and the median time from the first complaints to diagnosis was 2 months (range, 1 week to 70 months). Medulloblastomas and other embryonal tumors (47), low-grade gliomas (32), and high-grade gliomas (22) were the most commonly diagnosed malignancies. Ependymomas, craniopharyngiomas, germ cell tumors, and other malignancies were observed in 22 patients. For 26 patients, no histopathological or radiological diagnosis was available. Follow-up information was available for 98 (65.8%) patients. The 5-year OS rate for the whole study group was 67.7%. CONCLUSION: Consistent with international data, embryonal tumors, and gliomas were the most commonly diagnosed CNS malignancies in Armenia. Multimodal treatment was often not available in Armenia during the study period, especially for early cases.

ON THE RESULTS OF A SYSTEMIC MULTIFACTOR ANALYSIS WITH MATHEMATICAL MODELING OF THE INDICATORS OF MEDICAL EXPERTISE OF YOUNG MALES WITH SURGICAL DISEASES IN THE REPUBLIC OF ARMENIA.

Medical aspects of the organization of replenishment of the Armed Forces with healthy and physically strong personnel are of great importance, and the deficit in the number of conscripts and their low-quality condition have become one of the main and important problems for the Armed Forces. The aim of the study was to improve the medical care of male conscripts aged 18-27 years by revealing the regularities and peculiarities of the expert assessment of surgical diseases among this category of young men on the basis of mathematical modeling. The object of the research was the study of the names of surgical profile articles, according to which these people were recognized as unfit or restricted fit for service, and the results of military medical expertise. Descriptive, social, and statistical methods were applied in the course of the study. The final stage was to conduct a systemic multifactor analysis in order to obtain a mathematical model of the process under study. The values of the influence coefficients of the mentioned indicators for 2013-2019 on the obtained mathematical models from the point of view of military-medical expertise of young men with surgical diseases both in the Republic of Armenia as a whole and in its separate regions are presented. Summarizing, it can be stated that from the point of view of military-medical expertise of young men with surgical diseases it is impossible to consider Yerevan city and the regions of RA as separate parts of the Republic of Armenia. Yerevan and the regions of the Republic of Armenia as separate parts, as they appear as a single whole according to the results of systemic multifactor analysis with mathematical modeling.
