Surveillance Metrics and History of the COVID-19 Pandemic in Central Asia: Updated Epidemiological Assessment.

BACKGROUND: This study updates the COVID-19 pandemic surveillance in Central Asia we conducted during the first year of the pandemic by providing 2 additional years of data for the region. The historical context provided through additional data can inform regional preparedness and early responses to infectious outbreaks of either the SARS-CoV-2 virus or future pathogens in Central Asia. OBJECTIVE: First, we aim to measure whether there was an expansion or contraction in the pandemic in Central Asia when the World Health Organization (WHO) declared the end of the public health emergency for the COVID-19 pandemic on May 5, 2023. Second, we use dynamic and genomic surveillance methods to describe the history of the pandemic in the region and situate the window of the WHO declaration within the broader history. Third, we aim to provide historical context for the course of the pandemic in Central Asia. METHODS: Traditional surveillance metrics, including counts and rates of COVID-19 transmissions and deaths, and enhanced surveillance indicators, including speed, acceleration, jerk, and persistence, were used to measure shifts in the pandemic. To identify the appearance and duration of variants of concern, we used data on sequenced SARS-CoV-2 variants from the Global Initiative on Sharing All Influenza Data (GISAID). We used Nextclade nomenclature to collect clade designations from sequences and Pangolin nomenclature for lineage designations of SARS-CoV-2. Finally, we conducted a 1-sided t test to determine whether regional speed was greater than an outbreak threshold of 10. We ran the test iteratively with 6 months of data across the sample period. RESULTS: Speed for the region had remained below the outbreak threshold for 7 months by the time of the WHO declaration. Acceleration and jerk were also low and stable. Although the 1- and 7-day persistence coefficients remained statistically significant, the coefficients were relatively small in magnitude (0.125 and 0.347, respectively). Furthermore, the shift parameters for either of the 2 most recent weeks around May 5, 2023, were both significant and negative, meaning the clustering effect of new COVID-19 cases became even smaller in the 2 weeks around the WHO declaration. From December 2021 onward, Omicron was the predominant variant of concern in sequenced viral samples. The rolling t test of speed equal to 10 became entirely insignificant for the first time in March 2023. CONCLUSIONS: Although COVID-19 continues to circulate in Central Asia, the rate of transmission remained well below the threshold of an outbreak for 7 months ahead of the WHO declaration. COVID-19 appeared to be endemic in the region and no longer reached the threshold of a pandemic. Both standard and enhanced surveillance metrics suggest the pandemic had ended by the time of the WHO declaration.

May Measurement Month 2021: an analysis of blood pressure screening results from Armenia.

Elevated blood pressure (BP) is a growing burden worldwide and is the leading cause of mortality and disability-adjusted life years all over the world. May Measurement Month (MMM) is a global initiative aimed to increase awareness of high BP initiated by the International Society of Hypertension, to identify individuals in need of improved hypertension care, and to improve BP screening worldwide. An opportunistic cross-sectional survey of volunteers aged ≥18 years was carried out in accordance with standard MMM protocol in 2021. The study was conducted in public areas, both indoor and outdoor, as well as in primary and secondary healthcare centres. A total of 5777 individuals (mean age 51.8 ± 16.1 years, 49.8% female) were screened. After imputation, 45.7% participants had hypertension and 43.7% of them were aware of their high BP. Of 2640 participants with hypertension, 887 (33.6%) were on antihypertensive treatment, of whom 32.4% were on single medication, 29.7% on two medications, and 37.9% on three or more. Only 42.2% of those on medication had controlled BP (<140/90 mmHg), whereas of the participants with hypertension overall, 14.2% had controlled BP. We found that the prevalence of inadequately treated hypertension remains high in Armenia and may represent a vital contributor to the growing burden of non-communicable diseases.

Telemedicine is now legal in Armenia, how to make it a routine clinical practice?

Armenia's early adoption of telemedicine began with the National Aeronautics and Space Administration (NASA) collaboration following the 1988 Spitak earthquake, providing critical medical support. The 2022 legalization of telemedicine by the Armenian Ministry of Health marked a significant step toward improving healthcare delivery. Current regulations only apply to doctors and lack clear terminology for different telemedicine interactions, highlighting the need for broader and more inclusive policies. Despite regulatory progress, telemedicine adoption in Armenia faces challenges such as insufficient digital literacy, infrastructure, and integration into medical education and practice.

Allelic frequencies of polymorphism c.521T>C (rs4149056) favor preemptive SLCO1B1 genotyping in Armenia.

OBJECTIVES: Statins represent an important pharmacological factor for the prevention of cardiovascular diseases but may also cause severe cases of myotoxicity. Numerous studies have described the association of the SLCO1B1 gene variant c.521C with statin-induced myopathy across different populations. This study aimed at evaluating the usefulness of preemptive SLCO1B1 genotyping in Armenia. METHODS: A total of 202 Armenian patients referred to the Center of Medical Genetics and Primary Health Care in Yerevan for upper respiratory tract infection between January and May 2022 were included in this study. Genotyping for SLCO1B1 c.521T>C (rs4149056) was performed using a commercially available real-time PCR assay (RealFast™). RESULTS: In total, 3/202 (1.5 %) samples were C/C homozygotes and 52/202 (25.7 %) were T/C heterozygotes, associated with a high and increased risk for statin-induced myopathy, respectively. The SLCO1B1 c.521C allelic frequency was 14.4 %. CONCLUSIONS: The observed allele frequency of 14.4 % for the c.521C variant is slightly lower than frequencies reported from Europe, but relatively high compared to Asian populations, suggesting that preemptive SLCO1B1 genotyping could be a useful approach for the reduction of statin-induced adverse effects in Armenia.

Plasminogen activator inhibitor-1 genotype 4G/5G associates with skin involvement in Armenian familial Mediterranean fever patients.

There is little and conflicting data on the role of the plasminogen activator inhibitor-1 (PAI-1, SERPINE1) 4G/5G polymorphism in familial Mediterranean fever (FMF). Therefore this study aimed at evaluating the impact of this polymorphism on the disease course in a cohort of 303 Armenian FMF patients. Genotyping for 12 Mediterranean fever (MEFV) gene mutations and the PAI-1 4G/5G (rs1799762) polymorphism were performed by PCR/reverse-hybridization (StripAssay) and real-time PCR, respectively. PAI-1 genotypes 4G/4G, 4G/5G, and 5G/5G could be identified in 4 (5.88%), 30 (18.63%) and 9 (12.16%) patients with erysipelas-like erythema (ELE), while this was the case for 64 (94.12%), 131 (81.37%), and 65 (87.84%) patients without ELE, respectively (P < 0.033). We have identified a significant relationship between the PAI-1 4G/5G genotype and the occurence of ELE in a relatively large cohort of Armenian FMF patients. Because of conflicting results concerning the impact of this polymorphism on the clinical course of FMF in different populations, further studies are desirable to substantiate the findings reported here.

Costs of in- and outpatient respiratory disease and the seasonal influenza vaccination program in Armenia - 2020-2021.

BACKGROUND: Despite the substantial global impact of influenza, there are limited economic data to guide influenza vaccination programs investments in middle-income countries. We measured the costs of influenza and the costs of an influenza vaccination program in Armenia, using a societal perspective. METHODS: During December 2022 through March 2023, retrospective cost data were collected from case-patients and healthcare providers through structured questionnaires at 15 healthcare facilities selected through stratified sampling. Medical costs included medications, laboratory costs, laboratory and diagnostic tests, and routine health care service costs and direct and indirect societal costs were included. Vaccination program costs from the 2021-2022 influenza season were identified using accounting records and categorized as: planning, distribution, training, social mobilization and outreach, supervision and monitoring, procurement, and national- and facility-level administration and storage. RESULTS: The mean costs per episode for SARI and ILI case-patients were $US 823.6 and $US 616.57, respectively. Healthcare service costs were the largest direct expenses for ILI and SARI case-patients. Total costs of the 2021-2022 influenza vaccination program to the government were $US 4,353,738, with the largest costs associated with national- and facility-level administration and storage (30% and 65% respectively). The total cost per dose administered was $US 25.61 ($US 7.73 per dose for procurement and $US 17.88 for the marginal administration cost per dose). CONCLUSIONS: These data on the costs of seasonal influenza prevention programs and the societal costs of influenza illness in Armenia may inform national vaccine policy decisions in Armenia and may be useful for other middle-income countries. Influenza vaccines, like other vaccine programs, are recognized as substantially contributing to the reduction disease burden and associated mortality and further driving economic growth. However, a formal cost-effectiveness analysis should be performed once burden of disease data are available.

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.

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.

Emergency medical services in Armenia: national call trends and future directions.

BACKGROUND: Emergency medical services (EMS) are paramount to boosting health indices in lower-middle income countries (LMICs); however, lack of uniform data collection and analysis hinders system improvement efforts. In the present study, we describe patterns of EMS utilization in the Republic of Armenia and provide key insight into the quality of digital data collection methods. RESULTS: For calls logged in the capital city, Yerevan, the majority had at least one missing field. The predominant complaint was high blood pressure among adults (34.4%) and fever among pediatrics (65.9%). A majority of patients were female (57.6%), adults (90.2%), and not transported to a hospital (85.0%). In the rural provinces, the data was largely intact. The predominant complaints were unspecified acute condition (27.4%) and high blood pressure (26.2%) among adults, and fever (43.9%) and unspecified acute condition (22.1%) among pediatrics. A majority of patients were female (57.1%), adults (94.2%), and not transported to a hospital (78.9%). CONCLUSIONS: Our study reveals that the majority of calls to the EMS system are for concerns not needing in-hospital treatment and for acute exacerbation of chronic conditions. Our study also provides a critical foundation for the improvement of EMS systems in Armenia and in other nations in transition. The Locator software has the potential to be a valuable tool to the MoH if it is improved for surveillance purposes, and future synchronization of digital systems would provide easy access to critical information on population health needs and the effectiveness of public health interventions.

Historical evolution of healthcare systems of post-soviet Russia, Belarus, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, Armenia, and Azerbaijan: A scoping review.

This scoping review addresses the transformation and development of new healthcare systems in nine countries -Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Russia, Tajikistan, Turkmenistan, and Uzbekistan over the period following the collapse of the Soviet Union from 1991 to the present. This assessment focuses on maternal and child health, mental health, communicable diseases, and non-communicable diseases in an effort to highlight the changes in the healthcare status of these nine countries under scrutiny. Considering that all the post-Soviet nations are officially recognized members of the World Health Organization (WHO) and have demonstrated their commitment to attaining the WHO's objectives, the evaluation of healthcare system progress and improvement was carried out utilizing indicators provided by the WHO. This review reveals that the evolution of healthcare systems could be considered sustainable, given that average life expectancy has returned to the level it was in 1991- the year of the USSR's breakup, and people's health has improved since the turn of the twenty-first century. To enhance the potential success of future healthcare reforms, however, governments must monitor implementation of the reform process, evaluate the achievement of objectives, and make necessary adjustments. The success of future healthcare changes will depend on the active involvement of the government, medical community, and patient community, as well as obtaining the support of local health authorities. This study may help identify successful and failed strategies, guiding future healthcare changes and investments.

Preliminary investigations of parasite contamination of water sources in Armenia.

The intestinal protozoan parasites, Cryptosporidium and Giardia, are known to have a global distribution, infecting and causing disease in a range of hosts, including people, livestock, pets, and wildlife. However, data from some regions is very sparse. In Armenia, in the Caucasus region of West Asia, only scanty data are available, with just a few surveys on Cryptosporidium infections in livestock, and no available data on human infections or environmental contamination. As part of implementation of water analysis methods for these parasites in Armenia, 24 raw water samples and two sediment samples were analysed for these parasites using a range of approaches, including modified Ziehl-Neelsen, Lugol stain, immunofluorescent antibody test (IFAT), qPCR and, on sediment samples, immunomagnetic separation and IFAT. Results suggest substantial contamination of raw water sources and indicate the need for further targeted studies using appropriate methods and collecting data on host infections in catchment areas.

Assessing the Adoption of One Health Approaches in National Plans to Combat Health Threats: The Pilot of a One Health Conceptual Framework in Armenia.

Due to several factors, such as environmental and climate changes, the risk of health threats originating at the human-animal-environment interface, including vector-borne diseases (VBDs) and zoonoses, is increasing. Low-resource settings struggle to counter these multidimensional risks due to their already-strained health systems and are therefore disproportionally affected by the impact caused by these changes. Systemic approaches like One Health (OH) are sought to strengthen prevention and preparedness strategies by addressing the drivers of potential threats with a multidisciplinary and multisectoral approach, considering the whole system at the human-animal-environment interface. The integration of OH in national plans can be challenging due to the lack of effective coordination and collaboration among different sectors. To support the process of knowledge coproduction about the level of OH integration in prevention and preparedness strategies against health threats in Armenia, a situation analysis was performed on Crimean-Congo hemorrhagic fever/virus and anthrax (identified by local stakeholders as priorities to be addressed with the OH approach), and actions to strengthen the national OH system were identified with the support of a OH conceptual framework. The study highlighted that multidisciplinary and multisectoral efforts towards prevention and preparedness against VBDs and zoonoses threats need to be strengthened in Armenia, and priority actions to integrate the OH approach were identified.

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.

Wild grapes of Armenia: unexplored source of genetic diversity and disease resistance.

The present study is the first in-depth research evaluating the genetic diversity and potential resistance of Armenian wild grapes utilizing DNA-based markers to understand the genetic signature of this unexplored germplasm. In the proposed research, five geographical regions with known viticultural history were explored. A total of 148 unique wild genotypes were collected and included in the study with 48 wild individuals previously collected as seed. A total of 24 nSSR markers were utilized to establish a fingerprint database to infer information on the population genetic diversity and structure. Three nSSR markers linked to the Ren1 locus were analyzed to identify potential resistance against powdery mildew. According to molecular fingerprinting data, the Armenian V. sylvestris gene pool conserves a high genetic diversity, displaying 292 different alleles with 12.167 allele per loci. The clustering analyses and diversity parameters supported eight genetic groups with 5.6% admixed proportion. The study of genetic polymorphism at the Ren1 locus revealed that 28 wild genotypes carried three R-alleles and 34 wild genotypes carried two R-alleles associated with PM resistance among analyzed 107 wild individuals. This gene pool richness represents an immense reservoir of under-explored genetic diversity and breeding potential. Therefore, continued survey and research efforts are crucial for the conservation, sustainable management, and utilization of Armenian wild grape resources in the face of emerging challenges in viticulture.

Factors Associated with the Uptake of Rotavirus and Pneumococcal Conjugate Vaccines among Children in Armenia: Implications for Future New Vaccine Introductions.

Advances in vaccinology have resulted in various new vaccines being introduced into recommended immunization schedules. Armenia introduced the rotavirus vaccine (RV) and the pneumococcal conjugate vaccine (PCV) into its national schedule in 2012 and 2014, respectively. Using data from the Armenia Demographic and Health Survey, the uptake of the RV and the PCV among children aged younger than three years was estimated. Multilevel logistic regression models were used to evaluate individual- and community-level factors associated with uptake. Intra-cluster correlations were estimated to explain variations in uptake between clusters. The uptake proportionof each RV dose were 90.0% and 86.6%, while each PCV dose had values of 83.5%, 79.4%, and 75.5%, respectively. Non-uptake was highest among children less than 6 months old, children with one sibling, children from a wealthy family, or children whose living distance to a health clinic was problematic. Significant variability in non-uptake due to cluster differences was found for both RV doses (30.5% and 22.8%, respectively) and for the second PCV dose (53.9%). When developing strategies for new vaccine implementation, characteristics of the child, such as age, siblingship, and distance to a health clinic or residence, should be considered. Further exploration of cluster differences may provide insights based on the increased uptake of these and other new vaccines.

Medical Education in Armenia: An Overview.

This article serves to describe the medical education system of Armenia, a country located in the cross-section of Europe and Asia. Similar to other countries in the region, its medical education system is structured into undergraduate (6 years), postgraduate (1-4 years), and continuing education components. Its largest medical university, Yerevan State Medical University (YSMU), is the predominant institute for medical education and has enrollment of not only Armenian citizens, but also international students from India, Iran, Russia, and other countries. According to publication metrics, research activity at YSMU is increasing. Finally, the unique relationship between the country and its global diaspora has facilitated collaborative efforts in not only medical education, but also the delivery of care and capacity building. Significant challenges remain for each stage of medical education, such as the lack of standardized licensing or board examinations and oversight of the number of resident physicians per specialty.

Establishing urogynecology subspecialty in Armenia: The Armenia project.

It is well known that there are many countries in the world where Urogynecology is not an existing subspecialty, and women are not receiving appropriate care for their pelvic floor disorders (PFD). One of these countries is the Republic of Armenia. Given the lack of expertise in the field of Urogynecology in Armenia, we conducted a study on the prevalence of PFDs and the degree of bother among women of all ages across the country, which was published in 2020. This led to the creation of the International Urogynecology Association for Armenia, comprising seven physicians from different countries: five from the USA, one urogynecologist from Lebanon, and one urologist from Russia. We implemented hybrid teaching based on Zoom lectures, case presentations, journal clubs, and live visits of mentors to Armenia on a regular basis to see patients and operate with our five fellows. We introduced our fellows to research and statistics by assigning research topics for different projects. Our fellows presented evidence-based presentations and extensive literature reviews on a regular basis. Our program will continue to grow the next 2-3 years. The success of this project holds significance for governmental, public, and healthcare entities in Armenia and across the world, where this subspecialty is non-existent, in preparing future female pelvic surgeons to care for the growing needs of women with these conditions. Replicating this program in other parts of the world will compound the benefits and successes of Urogynecology care across different societies, cultures, and people around the globe.

Lung cancer screening beliefs in Armenia.

Introduction: In Armenia, an upper-middle income country, 93% of deaths are from non-communicable diseases and over half of the male population smokes. Armenia has more than double the global lung cancer incidence. Over 80% of lung cancer is diagnosed at stages III or IV. However, there is a significant mortality benefit in detecting early-stage lung cancer via screening with low-dose computed tomography. Methods: This study employed a rigorously-translated, previously-validated survey based on the Expanded Health Belief Model to understand how Armenian male smokers' beliefs would affect lung cancer screening participation. Results: Survey responses highlighted key health beliefs that would mediate screening participation. Most respondents felt they were at risk for lung cancer, but over 50% also believed their cancer risk was equivalent to (or less than) non-smokers' risk. Respondents also overwhelmingly agreed a scan could help detect cancer earlier, but fewer agreed early detection could reduce cancer mortality. Important barriers included absence of symptoms and costs of screening and treatment. Discussion: Overall, the potential to reduce lung cancer-related deaths in Armenia is high, but there are a number of central health beliefs and barriers that would limit screening uptake and effectiveness. Improved health education, careful consideration of socioeconomic screening barriers, and appropriate screening recommendations may be useful in overcoming these beliefs.

Health Informatics Training Program in Low and Middle Income Countries.

We developed the first health informatics training program in Armenia and in the Caucasus region. The training program consists of four educational pillars, including a bootcamp, an individualized training program, a capstone, and a scholarly project. We conducted surveys and qualitative interviews to evaluate the training program. With trending positive results we acknowledge that it is important to understand the landscape of health informatics and conduct needs assessment prior to establishing such a training program in an LMIC.

Multidimensional Deprivation from Labor Market Opportunities in Armenia: Evidence from 2018 and 2020.

This paper explores the multidimensional deprivation from labor market opportunities in Armenia by constructing a Quality of Employment measure. Using Labor Force Survey datasets for the years 2018 and 2020, we conduct a comparative analysis for a group of job-separated individuals. The identified dimensions of deprivation from labor market opportunities prior to and after the onset of COVID-19 are reasons for separating from a job, reasons for not looking for a job, and main obstacles in finding a job. These dimensions enable to study employee-level (supply factors) and job-related characteristics (demand factors). Our study shows that demand factors are the primary drivers of amplified deprivation in times of the pandemic. Also, we observe that the gender gap in the labor market deprivation has been increased during the pandemic, further amplified for married women. Interestingly, gender gap in deprivation is invariant to the occupational composition.
