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.

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.

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.

Predicting COVID-19 vaccination uptake in Armenia using the Health Belief Model: Results from a nationwide survey

Health behavior theories have been effectively used for studying populations' awareness, attitudes, and beliefs related to COVID-19 preventative behaviors. The aim of this study was to explore the factors associated with the intention to get vaccinated against COVID-19 in the Armenian population using the Health Belief Model (HBM) as a framework. We applied stratified two-stage random sampling to conduct a telephone survey of 3,483 adults in 2021. The multi-domain survey instrument included questions on socio-demographic characteristics, COVID-19-related knowledge, COVID-19 susceptibility, severity and self-efficacy beliefs, sources of information on COVID-19, COVID-19 vaccination practice, and its benefits and barriers. We performed bivariate and hierarchical multivariate regression analysis with the entry of variables in blocks. In total, about 12% of the sample (n = 393) was vaccinated against COVID-19. Of 2,838 unvaccinated participants, about 53% (n = 1516) had an intention to get vaccinated. The final hierarchical logistic regression model containing socio-demographic characteristics, knowledge about COVID-19, and HBM constructs explained 43% of the variance in the intention to get vaccinated against COVID-19. Participants' age, employment status, average monthly expenditures, perceived threat, benefits, perceived barriers, self-efficacy, and cues to action were significant and independent predictors of the intention to get COVID-19 vaccination. This study confirmed the utility of the HBM in highlighting drivers of an important health-protective behavior in the context of pandemics. Health policy makers, communication specialists, and healthcare providers should particularly stress the effectiveness and safety of the vaccines in their efforts to increase vaccination rates and focus on unemployed and low-income population groups.

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.

Young Age of Alveolar Echinococcosis Patient in Armenia: A Case Report

Human alveolar echinococcosis (AE) remains a serious public health concern in endemic areas and a challenge for clinicians. Here a confirmed case of human AE in a patient from Armenia who had not visited a known Echinococcus multilocularis endemic area is reported. In October 2012, a 12-year-old girl from a little Armenian village, presented with paroxysmal pain in the right lumbar area to the children's medical center (MC). The girl mentioned having close contact with an animal, like a cat. She was admitted to the surgical department with a diagnosis of a malignant liver tumor in the right lobe. In November 2012, the patient underwent laparotomy, removal of the hepatic lesion and abdominal cavity drainage. The histopathological examination of the biopsy material confirmed the main diagnosis of liver AE with suppurative lesions. The patient was given albendazole (ABZ) following 20 days in the hospital, but she stopped receiving the preventive chemotherapy at home and even missed the dispensary visits. It later caused complications, and in July 2016, the child had once again surgery. In January 2017, the child was readmitted to the MC with no content from the external biliary drainage tube in the previous 6 hours. Bile flow improved after flushing the drainage with saline solution and suturing the enterostomy tube. In February 2017, the child visited MC for examination, and the drainage of the bile ducts was blocked, although she had neither discomfort nor jaundice. It was recommended to continue the patient's follow-up, to receive ABZ and to undergo a liver transplant surgery.

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.

Characteristics of stroke service implementation in Armenia

Background

Acute stroke care service in Armenia was established in 2019 after the implementation of the National Stroke Program (NSP). This study aimed to provide an up-to-date account of the current image and clinical characteristics of acute stroke service implementation at a tertiary hospital in Armenia by analyzing the quality of care and identifying the areas that need improvement.

Methods

We analyzed patient data from a single hospital in 1 year after the establishment of acute stroke care service (February 2021-January 2022). We selected patients who were within 0-24 h from symptom onset at admission and included patients who benefited from reperfusion therapies (intravenous thrombolysis (IVT) and/or endovascular thrombectomy (EVT)). A favorable outcome was defined as a drop in the National Institutes of Health Stroke Scale (NIHSS) by more than four points at discharge and a modified Rankin score (mRS) of 0-2 at 90 days.

Results

Of the total 385 patients, 155 underwent reperfusion therapies, 91% of patients (141/155) arrived by ambulance, 79.2% (122/155) had neurological improvement at discharge, and 60.6% (94/155) had an mRS of 0-2 at 3 months. Less than 5% of patients had early direct access to the rehabilitation center.

Conclusion

Our study demonstrated that the implementation of NSP with organized protocol-driven inpatient care led to significant advancement in acute stroke service performance. We believe that our report will serve as a model for achieving advanced and structured stroke care in a resource-limited context and contribute to the future development of the healthcare system in our country.

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.

Stroke care in Armenia: Recent developments

Introduction

Armenia is an upper-middle-income country with a population of nearly 3 million. Stroke is one of its major public health problems and ranks as the sixth leading cause of death, with a mortality of 75.5 per 100,000.

Methods and results

Until recently, modern stroke care was not available in Armenia. During the past 8 years substantial advances have been made in building medical infrastructure and delivering acute stroke care. This manuscript describes contributors to this progress, including extensive and long-term collaboration with international stroke experts, the development of hospital-based stroke teams, and a funding commitment for stroke care by the government.

Conclusion

The results of acute stroke revascularization procedures during the past 3 years are reviewed and found to meet international standards. Future directions are discussed including the immediate need to expand acute stroke care to underserved parts of the country by adding primary and comprehensive stroke centers. An active educational program for nurses and physicians and the TeleStroke system development will help support this expansion.

Prevalence of Pretreatment HIV-1 Drug Resistance in Armenia in 2017-2018 and 2020-2021 following a WHO Survey

The increased antiretroviral therapy (ART) coverage of patients in the absence of routine genotyping tests and in the context of active labor migration highlight the importance of HIV-1 drug resistance (DR) surveillance in Armenia. We conducted a two-phase pretreatment DR (PDR) study in 2017-2018 (phase I; 120 patients) and 2020-2021 (phase II; 133 patients) according to the WHO-approved protocol. The analysis of HIV-1 genetic variants showed high degrees of viral diversity, with the predominance of A6. The prevalence of any PDR was 9.2% in phase I and 7.5% in phase II. PDR to protease inhibitors was found only in 0.8% in phase II. PDR to efavirenz and nevirapine was found among 5.0% and 6.7% of patients in phase I, and 6.0% and 6.8% of patients in phase II, respectively. The prevalence of PDR to nucleoside reverse-transcriptase inhibitors decreased from 5.0% in phase I to 0.8% in phase II. In addition, we identified risk factors associated with the emergence of DR-male, MSM, subtype B, and residence in or around the capital of Armenia-and showed the active spread of HIV-1 among MSM in transmission clusters, i.e., harboring DR, which requires the immediate attention of public health policymakers for the prevention of HIV-1 DR spread in the country.

Very low frequency of the lactase persistence allele LCT-13910T in the Armenian population

Primary lactose malabsorption is characterised by a down-regulation of lactase activity after weaning and inability to digest lactose in adulthood. It has been suggested that the historical introduction of dairying led to a positive selection for lactase persistence variants in a regulatory region upstream of the LCT gene. Here, we genotyped 202 Armenian subjects for LCT-13910T, a lactase persistence variant which is widespread in Europeans. The homozygous C/C genotype associated with primary hypolactasia, the heterozygous C/T and the homozygous T/T lactase persistence genotypes were found in 191 (94.6%), 11 (5.4%), and 0 (0.0%) samples, respectively. The frequency for the LCT-13910*T allele was 2.7%. The observed allele frequency of 2.7% for LCT-13910T is even lower than previously reported and supports current phenotypic data about lactose malabsorption in Armenia.

Progress Update: Development of Palliative Care From 2017 to 2020 in Five Countries in Eurasia

CONTEXT

In the early 2000s, palliative care was largely unknown in the Eurasian region. For a period of twenty years starting around 2002, Open Society Foundations (OSF) supported palliative care pioneers in the region to establish palliative care services, train health providers, and advocate for the integration into health services.

OBJECTIVES

To report on the development of palliative care in Armenia, Georgia, Moldova, Tajikistan and Ukraine during the period 2017-2021 and explore the impact of OSF's sustained funding for palliative care in these countries. Activities and developments to 2017 were described in country-specific papers in 2018.

METHODS

A retrospective case study analysis was used to examine how palliative care developed in each country. We reviewed theories of change, funding and advocacy strategies, implemented activities and interventions, and their outputs and outcomes, and compared them to legal, policy and service developments in practice.

RESULTS

By the mid-2010s, each country had laid the foundations for rolling out palliative care-basic policies and guidelines were in place; palliative care medications were available; key health providers were trained; and training capacity and models of care had been created-but service availability remained limited. In subsequent years, advocates increasingly embraced public advocacy to hold governments accountable for meeting their commitments and to include palliative care in universal health insurance. By 2021, Armenia, Moldova, and Ukraine had significantly scaled up service availability and palliative care was firmly embedded in universal health coverage in Moldova and Ukraine whereas progress in Georgia and Tajikistan was more modest.

CONCLUSION

Experiences in these countries suggest that a strategy that initially emphasizes training, technical assistance, and engagement to create the building blocks for palliative care combined with or followed by public advocacy and campaigning to demand roll out of services can result in significant advances. Continued progress, however, is not guaranteed, especially considering the COVID-19 pandemic and dwindling donor support.

Palliative Care education in Armenia: perspectives of first-year Armenian physician residents

Background

Due to developing demographic changes, including an aging society and the increasing prevalence of non-communicable diseases, Palliative Care is increasingly highlighted as a universal healthcare need. The need for Palliative Care in Armenia is set against the context of an underdeveloped healthcare system. Further, the absence of palliative medicine within medical education, particularly undergraduate education in Armenia presents a major barrier to improving care. This research aimed to assess the perception of young Armenian physicians’ understanding of Palliative Care, its perceived status in Armenia and the experience and influence of any engaged Palliative Care education.

Methods

Twenty Armenian first-year residents with different specializations were interviewed July and September 2016 regarding: understanding/knowledge, experiences, perceived competence, and expectations of Palliative Care and Palliative Care education. The transcripts from these semi-structured interviews were analyzed using Qualitative Content Analysis.

Results

Participants perceived that Armenia’s health care system lacked sufficient Palliative Care and Palliative Care education. Although elements of Palliative Care were included in different specialty teaching, this provided just a partial understanding of typical Palliative Care patients/symptoms, approaches to holistic care, and crucially key communication skills. Challenges noted by participants in caring for Palliative Care patients included emotional difficulties, communication of diagnosis/prognosis, uninformed patients and concerns for patients, families, and physicians. Self-confidence in caring for patients with incurable illness varied. Participants hoped for increasing availability and accessibility of Palliative Care, and extension of clinical education in Palliative Care at all levels (undergraduate, postgraduate, specialization).

Conclusions

Absence of training has resulted in misconceptions and ignorance of common concepts and practices in Palliative Care. Palliative Care education needs to be systematically developed and integrated into clinical training within Armenia. This research may provide a rallying call for changes within the core curricula in Armenia and may also encourage collaborative development in associated countries of the Caucasus region.

Incidence patterns and review of Hodgkin lymphoma in the Republic of Armenia

Hodgkin lymphoma (HL) accounts for roughly 10% of all lymphomas and 0.6% of all malignant tumours analysed worldwide yearly. Data regarding HL in developing world are exceptionally constrained. The main objective of this research is to investigate the incidence patterns of HL within the Republic of Armenia and to portray disease distribution according to age and sex. There is a very strict evidence on the frequency of HL in Armenia. The results of our research find out that the frequency of HL in Armenia has not changed altogether over the past 15 years and is comparable to that detailed from the USA and Europe.

Qualitative study of barriers and facilitators of health entrepreneurship in rural and semirural communities of Armenia

INTRODUCTION

Low- and middle-income countries often face the issue of unequal distribution of healthcare services and human resources between rural and urban areas. Globally, there are many factors negatively affecting the willingness of physicians to work in remote and rural areas, such as low wages, poor living conditions, poorer and sicker patients, suboptimal equipment and supplies, and a lack of quality infrastructure and transportation.

METHODS

This study explored the perceptions of barriers and facilitators of medical entrepreneurship and the impact of medical entrepreneurship on the served communities among the owners of private medical practices in rural and semirural areas of Armenia. The researchers conducted qualitative in-depth interviews with the 13 owners of 12 private practices. The interviews were transcribed in the original language (Armenian). Only the quotes were translated into English. The direct content analysis approach was used for analyzing textual data.

RESULTS

The findings of the study suggest that high investment cost, intense competition with state facilities, unfavorable laws and regulations, and a lack of entrepreneurship and healthcare quality assurance skills were perceived as barriers to establishing and running private healthcare practices. The dissatisfaction of healthcare providers with their work conditions in state facilities, the instability of the job market in Armenia, and the development of clear marketing strategies by the entrepreneurs facilitated opening and operating private practices. All of the interviewees felt that their practices had a positive impact on the communities they served, in terms of creating new jobs and introducing up-to-date and in-demand services into these communities.

CONCLUSION

The study recommended providing potential entrepreneurs with training in entrepreneurship and healthcare quality assurance and mentorship opportunities, as well as with tools to support financing their enterprises.

Overview of Cancer Control in Armenia and Policy Implications

Cancer is the second leading cause of death in Armenia. Over the past two decades, the country has seen a significant rise in cancer morbidity and mortality. This review aims to provide up-to-date info about the state of cancer control in Armenia and identify priority areas of research. The paper analyzes published literature and local and international statistical reports on Armenia and similar countries to put numbers into context. While cancer detection, diagnosis, and treatment are improving, the prevalence of risk factors is still quite high and smoking is widespread. Early detection rates are low and several important screening programs are absent. Diagnosis and treatment methods are not standardized; there is a lack of treatment accessibility due to insufficient government coverage and limited availability of essential medicines. Overall, there is room for improvement in this sector, as research is limited and multidisciplinary approaches to the topic are rare.

Comparison of Conditional and Marginal Models in Assessing a Child Nutrition Intervention in Armenia

INTRODUCTION

Child malnutrition is a major issue in conflict zones. Evidence-based interventions and their thorough evaluation could help to eliminate malnutrition. We aimed to assess the causal effect of a community-based multidisciplinary nutrition program for children in a chronic conflict zone near the northeastern border of Armenia on two main outcomes: stunting and anemia. We further compared the interpretations and public health relevance of the obtained effect estimates.

METHODS

In 2016, the study measured hemoglobin and anthropometric measures and collected data from the children's caregivers. We used propensity score matching analyses, inverse probability weighting, and overlap weighting methods to examine the average treatment effects among treated population (ATT), and among population with overlapping weights (ATO).

RESULTS

The ATT for stunting among children who participated in the intervention program estimated by propensity score matching analyses (PSM-ATT) was (1.95; 95%CI 1.15-3.28). Nevertheless, children who took part in the program had a lower risk of anemia (0.28; 95%CI 0.19-0.42). The ATT, estimated by inverse probability weighting (IPTW-ATT), was slightly lower for stunting (1.82; 95%CI 1.16-2.86) while similar for anemia (0.33; 95%CI 0.23-0.46) compared to PSM-ATT. Compared to the IPTW-ATT and PSM-ATT the ATO was lower for stunting (1.75; 95%CI 1.14-2.68) and similar for anemia (0.31; 95%CI 0.22-0.43).

DISCUSSION

Marginal models could be used in similar quasi-experimental settings to identify the causal effect of interventions in specific populations of interest. Nonetheless, these methods do not eliminate threats to internal validity. Thorough study design and accurate data collection are necessary to improve the efficiency of marginal models.

Managing multiple myeloma in a resource-limited region: Diagnosis and treatment in Armenia

Multiple myeloma (MM) is the second most common blood cancer in adults leading to 117,000 deaths every year. Major breakthroughs in clinical research of the past decades transformed the diagnosis and treatment of MM improving the survival rates and overall quality of life of patients. Unfortunately, scientific advancements are not distributed equally around the globe leading to disparities in the treatment outcomes between different regions of the world. Management of MM in low- and middle-income countries represents a big challenge for healthcare providers considering the economic, technological, and infrastructural restraints in comparison to developed countries. Many standards of practice, including diagnostic tools and therapeutic regimens, are not available in developing regions of the world. As an example of an upper-middle-income country, Armenia has been witnessing considerable progress in the diagnosis and treatment of MM, including but not limited to the establishment of autologous stem cell transplant (ASCT), accessibility to modern anti-myeloma medications, and improved diagnostic and monitoring workup. Despite significant improvements, there is still a need for refinement in the management of MM. The aim of this review article is to discuss the latest developments and the current diagnosis and treatment of MM in Armenia as an example of a resource-limited region.

Genetic Diversity of Armenian Grapevine (Vitis vinifera L.) Germplasm: Molecular Characterization and Parentage Analysis

Armenia is an important country of origin of cultivated Vitis vinifera subsp. vinifera and wild Vitis vinifera subsp. sylvestris and has played a key role in the long history of grape cultivation in the Southern Caucasus. The existence of immense grapevine biodiversity in a small territory is strongly linked with unique relief and diverse climate conditions assembled with millennium-lasting cultural and historical context. In the present in-depth study using 25 nSSR markers, 492 samples collected in old vineyards, home gardens, and private collections were genotyped. For verification of cultivar identity, the symbiotic approach combining genotypic and phenotypic characterization for each genotype was carried out. The study provided 221 unique varieties, including 5 mutants, from which 66 were widely grown, neglected or minor autochthonous grapevine varieties, 49 turned out to be new bred cultivars created within the national breeding programs mainly during Soviet Era and 34 were non-Armenian varieties with different countries of origin. No references and corresponding genetic profiles existed for 67 genotypes. Parentage analysis was performed inferring 62 trios with 53 out of them having not been previously reported and 185 half-kinships. Instability of grapevine cultivars was detected, showing allelic variants, with three and in rare cases four alleles at one loci. Obtained results have great importance and revealed that Armenia conserved an extensive grape genetic diversity despite geographical isolation and low material exchange. This gene pool richness represents a huge reservoir of under-explored genetic diversity.

May Measurement Month 2019: an analysis of blood pressure screening results from Armenia

Elevated blood pressure (BP) is an enormous public health problem and a growing burden worldwide and the biggest single risk factor for cardiovascular death. May Measurement Month (MMM) is a global initiative aimed to raise awareness of high BP and to act as a temporary solution to the lack of screening programmes worldwide. An opportunistic cross-sectional survey of volunteers aged ≥18 years was carried out in May to July 2019. Blood pressure measurement, the definition of hypertension and statistical analysis followed the standard MMM protocol. The study was conducted in public areas (23 sites in the capital city Yerevan and 13 in other regions), both indoor and outdoor, as well as in primary and secondary healthcare centres. In total, 9818 individuals (11.3% participated in either MMM2017/2018 or both) were screened of which 9786 had three BP measurements available, 1.6% of them reported never having had their BP measured. The mean age of screened participants was 47.6 (SD ± 16.5) years, 61.9% were female. After multiple imputation, 41.6% of participants had hypertension and 72.8% of them were aware of their high BP, 65.4% were on treatment, and of those treated, 46.5% had controlled BP (<140/90 mmHg). Of 4088 participants with hypertension, 30.4% had controlled BP. Of all risk factors analysed, reported use of anti-hypertensive medication and a previous diagnosis of hypertension were the strongest predictors of higher levels of BP. We found that the prevalence of hypertension, untreated and treated, but uncontrolled hypertension is still substantial in Armenia, which maybe a vital contributor to the growing burden of non-communicable diseases.

Eutrophication leads to the formation of a sulfide-rich deep-water layer in Lake Sevan, Armenia

Lake Sevan is a meso-eutrophic water body, which was severely impacted by anthropogenic level decrease, pollution and eutrophication during the last century. Starting in the 1970s, these processes resulted in the formation of an oxygen-depleted hypolimnion during summer-autumn stratification of the lake. In this work, we demonstrate for the first time that eutrophication of the lake leads not only to the full depletion of oxygen and nitrate in the hypolimnion but as well to the presence of sulfate-reducing microorganisms and toxic hydrogen sulfide. Concentrations of hydrogen sulfide in the hypolimnion of Major and Minor Sevan in October were as high as 9 and 39 μM, respectively. In October 2019, 66 % of lake's bottom was covered by sulfidic waters, while the fraction of sulfidic water volume reached 19 %. Values of δ³⁴S for hypolimnetic sulfide are lower by only 7-12 ‰ compared to epilimnetic sulfate, while δ³³S values of sulfide are similar to the δ³³S values of sulfate. These isotopic fingerprints are not consistent with microbial sulfate reduction as the sole source of hydrogen sulfide in the hypolimnion. We attribute the formation of a sulfidic deep-water layer to a combination of microbial sulfate reduction in the water column and diffusion of hydrogen sulfide from the sediments.

Investigating the Structure of Son Bias in Armenia With Novel Measures of Individual Preferences

Sex ratios at birth favoring boys are being documented in a growing number of countries, a pattern indicating that families selectively abort females. Son bias also explains why, in many countries, girls have more siblings and are born at relatively earlier parities compared with their brothers. In this study, we develop novel methods for measuring son bias using both questionnaire items and implicit association tests, and we collect data on fertility preferences and outcomes from 2,700 participants in Armenia. We document highly skewed sex ratios, suggesting that selective abortions of females are widespread among parents in our sample. We also provide evidence that sex-selective abortions are underreported, which highlights the problem of social desirability bias. We validate our methods and demonstrate that conducting implicit association tests can be a successful strategy for measuring the relative preference for sons and daughters when social desirability is a concern. We investigate the structure of son-biased fertility preferences within households, across families, and between regions in Armenia, using measures of son bias at the level of the individual decision-maker. We find that men are, on average, considerably more son-biased than women. We also show that regional differences in son bias exist and that they appear unrelated to the socioeconomic composition of the population. Finally, we estimate the degree of spousal correlation in son bias and discuss whether husbands are reliably more son-biased than their wives.

Intimate partner violence constrains timely utilisation of antenatal care services among Armenian women: Results from a nationally representative sample

Background:

Well-timed utilisation of antenatal care (ANC) services during pregnancy emphatically impact pregnancy outcomes. Intimate Partner Violence (IPV) predominance during pregnancy is exceptionally noticeable in Armenia, yet we have restricted information on the association between IPV and ANC attendance. The aim of this study was to determine the association between IPV and utilisation of adequate ANC services among Armenian women.

Methods:

A nationally representative sample survey from 2015 to 2016 Armenia Demographic and Health Survey was considered for this study. A total of 6116 women were interviewed. To estimate the association between outcome and explanatory variable, Pearson's Chi-square test followed by bivariate logistic regression analysis were performed.

Results:

About 58% of participants, more than 35 years old has encountered IPV. Women with advanced education (54.7%) attended ANC services between 0 and 3 months. It was found that only the richer women are two times more likely to visit ANC services above four times than other groups and its association with IPV claimed that richer women are more likely to face IPV. Moreover, women who are residing with alcoholic husbands/partners are two times more likely to suffer from partner abuse (P < 0.001).

Conclusion:

The impact of IPV on accessibility and timely utilisation of ANC services in Armenia cannot be overlooked as IPV is causing risk in healthy delivery and the country's overall productivity in a broader perception.

Evolution of radioecology in Armenia: a short review

PURPOSE

The article generalizes the evolution of radioecological studies conducted by female scientists in Armenia in the period of 1950-2020. Radioecological studies were launched in 1958, prior to the construction of the ANPP and major nuclear disasters.

CONCLUSION

The obtained results allowed the revealing peculiarities of distribution and accumulation of naturally occurring radioactive materials (NORM) and artificial radionuclides in the natural environment, urban sites and industrial centers. Series of national environmental monitoring programs were designed in order to reveal the main migration pathways of NORM and artificial radionuclides, as well as the assessment of exposure to natural and induced radiation.

The millipede tribe Brachyiulini in the Caucasus (Diplopoda, Julida, Julidae)

The diplopod tribe Brachyiulini is represented in the fauna of the Caucasus by eight genera and 32 species, of which one genus and 14 species are described as new: Colchiobrachyiulusmontanus Vagalinski, sp. nov., Iraniulustricornis Vagalinski, sp. nov., Omobrachyiulusarmatus Vagalinski, sp. nov., O.fasciatus Vagalinski, sp. nov., O.faxifer Vagalinski, sp. nov., O.kvavadzei Vagalinski, sp. nov., O.lazanyiae Vagalinski, sp. nov., O.ponticus Vagalinski, sp. nov., O.pristis Vagalinski, sp. nov., O.trochiloides Vagalinski, sp. nov., O.unugulis Vagalinski, sp. nov., O.zuevi Vagalinski, sp. nov., Svaniulusryvkini Vagalinski, gen. nov., sp. nov., and S.waltheri Vagalinski, gen. nov., sp. nov.Colchiobrachyiulus Lohmander, 1936, a former subgenus of Megaphyllum, is here elevated to a full genus, and the genus Grusiniulus Lohmander, 1936 is downgraded to a subgenus of the genus Cyphobrachyiulus Verhoeff, 1900, both stat. nov., with their previously described species, Colchiobrachyiulusdioscoriadis (Lignau, 1915) and Cyphobrachyiulusredikorzevi (Lohmander, 1936), respectively, listed as comb. nov.Omobrachyiulusbrachyurus (Attems, 1899) is formally established as a junior subjective synonym of O.caucasicus (Karsch, 1881), syn. nov., and Omobrachyiulusimplicitusritsensis (Golovatch, 1981) is formally synonymised with the typical Omobrachyiulusimplicitus (Lohmander, 1936), syn. nov.Omobrachyiulussevangensis (Lohmander, 1932), originally described in the genus Megaphyllum, is here transferred to the former genus, comb. nov. The diagnoses and descriptions of some genera and subgenera are refined and complemented. A key is given to all genera and species of Brachyiulini that occur in the Caucasus, and their distributions are mapped. Several species are recorded as new to the faunas of Armenia, Azerbaijan, Georgia, or Russia. The distribution patterns of the Caucasian Brachyiulini and their biogeographic implications are discussed.

Multiple myeloma in Armenia during the period 2006-2018: facts and discussion

Background

It is known that one of the reasons for the increased incidence of hematological malignancies is caused by the growth of multiple myeloma (MM). Worldwide, approximately 159,985 new cases of MM are diagnosed representing 0.9% of all cancer diagnoses and 106,105 patients will die from MM accounting for 1.1% of all cancer deaths per year. Despite significant advances in the MM treatment the mortality rates are still high. The presented study is the first accurate epidemiological study of ММ in Armenia for the period of 2006–2018.

Methods

The initial data for this retrospective cohort survey were derived from ambulance cards, hospitalization journals, and clinical data from the Registry of Blood Diseases at the Yeolyan Hematology Center.

Results

Data analysis showed that during 2006–2018 the average annual incidence for the MM was 1.2 per 100,000 population. A significant increase was observed in 2018 compared to 2006, 1.9 vs. 0.7 per 100,000 population. Interestingly, there were no sex differences in the overall MM incidence during the study period.

According to the received data, during the period of the 2006–2009 and 2014–2018 the 1-year survival rate for both sexes decreased dramatically from 83 to 64.1% at age group 60 years and below and from 78.5 to 68.1% in group 60 years and over. The 1-year overall survival (OS) for both sexes decreased by 18.9% for patients (≤60 age group) and 10.4% (> 60 age group) in the period of 2006–2009 to the period of 2014–2018.

Conclusions

The incidence rates for the MM increased during the analyzed period. Our study showed that males and females in the age group 60 years and below had better 5-year overall survival compared to elder ones and females have better survival.

The Psychosocial Impact of Compounding Humanitarian Crises Caused by War and COVID-19 Informing Future Disaster Response

The coronavirus disease 2019 (COVID-19) pandemic has caused the greatest global loss of life and economic impact due to a respiratory virus since the 1918 influenza pandemic. While health care systems around the world faced the enormous challenges of managing COVID-19 patients, health care workers in the Republic of Armenia were further tasked with caring for the surge of casualties from a concurrent, large-scale war. These compounding events put a much greater strain on the health care system, creating a complex humanitarian crisis that resulted in significant psychosocial consequences for health care workers in Armenia.

Explaining withdrawal's persistence: correlates of withdrawal use in Albania, Armenia, Jordan, and Turkey observed in a cross-sectional study

Background: Withdrawal dominates the contraceptive method mix in a geographical cluster of countries in South-Eastern Europe and Western Asia that have, in part, reached low fertility. This study examines the socio-demographic determinants associated with withdrawal use in Armenia, Albania, Jordan and Turkey that could explain withdrawal’s persistence and inform contraceptive programs in these unique settings.

Methods: Cross-sectional data on 31,569 married women 15 to 49 years were drawn from the Demographic and Health Surveys in Albania (2017-2018), Armenia (2015-2016), Jordan (2017-2018), and Turkey (2013). For each country, multinomial regression models estimating withdrawal use among all women and logistic regression models estimating withdrawal use among contraceptive users were used to evaluate the association with age, marital duration, parity, education, residence, and household wealth.

Results: The socio-demographic determinants associated with withdrawal use varied by country among all women and among all contraceptive users. While these associations were not all significant for all four countries general trends included that women were more likely to use withdrawal than not use contraception, but less likely to use withdrawal than other methods with increasing parity, higher education, and greater household wealth. Measures of association are reported by country for each correlate.

Conclusions: Despite the similar contraceptive mix in these four countries, no single set of factors was found to explain withdrawal’s persistence. Withdrawal’s prevalence in this geographical cluster may instead result from different balances of intertwined circumstances that include couples’ fertility decisions, access to modern contraception and availability of abortion services.

[Plastic surgery and fighting: Our experience during Nagorno-Karabakh war in 2020]

INTRODUCTION

This work relates the experience of three French surgical missions in the care of the war wounded during the armed conflict in Nagorno Karabakh which took place from September 27 to November 10, 2020.

MATERIALS AND METHODS

Three surgical missions were carried out in Armenia between October 2020 and January 2021. Surgeons intervened in different hospitals, at different times of the conflict and on various war wounds.

RESULTS

The presence of a plastic surgeon proved to be essential in the care of war wounded, especially in delayed emergency and secondary care. The ortho-plastic treatment offered during these missions has proven to be effective in the reconstruction of limbs. These missions made it possible to introduce the induced membrane technique of Masquelet AC in Armenia. During our visit to the Yerevan burn center, we mentioned the very probable use of white phosphorus as an etiology in several of the cases analyzed.

CONCLUSION

We relate the particular experience of civilian surgeons in the context of a modern armed conflict. The presence of a plastic surgeon proved to be indispensable in the care of war wounded and especially in their secondary reconstructions.

Identification of radionuclides' altitudinal distribution In soil and mosses In highlands of Armenia

The present study was conducted in mountain regions of Armenia with the aim to assess the activity concentrations of natural K-40 and artificial Cs-137 in soil and mosses and reveal the distribution similarities and differences. Most widespread moss species and surface soils were sampled concurrently from eight mountain ridges and massifs by different altitudinal belts. Statistical analysis revealed significant differences and opposite characteristics for K-40 and Cs-137. In case of K-40 the activity concentrations decreased in mosses by altitude but with no significant correlation. The mean activity concentrations of K-40 in the soils of different altitudinal belts are close, nevertheless, the higher activity concentrations are common for soils derived from ingenious rocks. For Cs-137 in mosses, the correlation with altitude is statistically insignificant, but the altitudinal dependence is noticeable within separate ridges and massifs. A significant correlation was identified between Cs-137 in soil, altitude and precipitation rate. Studying natural K-40 and artificial Cs-137 radionuclides together yielded interesting contrasting results confirming the dissimilar behaviour of radionuclides with different origins in the environment.

Challenges and Opportunities for Purchasing High-Quality Health Care: Lessons from Armenia

This paper examines how purchasing decisions in Armenia may contribute to barriers in using high-quality health care, particularly for non-communicable diseases, drawing on a review of the literature and key informant interviews. The paper adapts the strategic health purchasing progress framework, to examine how characteristics of purchasing, the health system, and the political, administrative, and macro-fiscal environment may have facilitated or hindered the attainment of service delivery goals. We conclude with six lessons for reforms aimed at improving the coverage and quality of health care in Armenia. First, increasing the political priority of access to quality of health care is a pre-requisite to advancing reforms to address these issues. Second, improved purchasing governance in Armenia will require a purchaser that can make decisions without political interference, with appropriate accountability mechanisms, improvements in technical capacity, and the routine use of data systems. Third, there is a need for the regulatory framework to ensure that revisions of the benefits package contribute to reducing the disease burden and improving access to care. Fourth, regulations governing quality-related criteria for provider selection should be enforced and include considerations for process quality. Fifth, payment incentives should be revised to encourage an increase in the supply of primary health care, reduce bypassing for hospital care, and improve the quality of services. Sixth, the potential of purchasing to improve service delivery will be dependent on increased pre-paid and pooled funds and better governance of the quality of care.

Intimate Partner Violence and Pregnancy Termination in Armenia: Evidence from Nationally-Representative Survey Data

Intimate partner violence has been associated with numerous consequences for women, including pregnancy termination. This study examined the association between predictive capacity of intimate partner violence and pregnancy termination among women in Armenia. The study analyzed the 2015-16 Armenia Demographic and Health Survey (ADHS) data on women aged 15-49 (Mean: 31.49; Standard Deviation, SD: 9.51). Marital control exercised by husbands, ever experienced physical violence, sexual violence, and emotional violence by husbands were the four indicators of intimate partner violence used in this study. To assess the association between intimate partner violence and pregnancy termination, a binary logistic regression model was fitted. After controlling for confounders, we found that women whose husbands exercised marital control were 26% more likely to experience pregnancy termination, compared to women whose husbands did not exercise marital control (adjusted odds ratio (aOR): 1.26, 95% Confidence interval (CI): 1.03-1.53). Women who ever experienced sexual violence were about 10 times likely to experience pregnancy termination than women who did not experience sexual violence (aOR: 9.76, 95% CI: 1.91-49.96). Both ever experienced physical violence and emotional violence did not have any significant associations with pregnancy termination. Forms of intimate partner violence are associated with pregnancy termination. The findings of this study provide evidence for government and policymakers to formulate, modify, and implement policies and program that target both men and women regarding the prevailing intimate partner violence and its consequences. Strengthening the policy implementation will ensure that women are empowered to make decisions about their reproductive health. Making husbands and their family members aware of the basics and consequences of intimate partner violence and focusing on child cognitive development which can be hampered due to the prevalence violence in families are recommended.

Factors associated with measles vaccination status in children under the age of three years in a post-soviet context: a cross-sectional study using the DHS VII in Armenia

BACKGROUND

The resurgence of measles globally and the increasing number of unvaccinated clusters call for studies exploring factors that influence measles vaccination uptake. Armenia is a middle-income post-Soviet country with an officially high vaccination coverage. However, concerns about vaccine safety are common. The purpose of this study was to measure the prevalence of measles vaccination coverage in children under three years of age and to identify factors that are associated with measles vaccination in Armenia by using nationally representative data.

METHODS

Cross-sectional analysis using self-report data from the most recent Armenian Demographic Health Survey (ADHS VII 2015/16) was conducted. Among 588 eligible women with a last-born child aged 12-35 months, 63 women were excluded due to unknown status of measles vaccination, resulting in 525 women included in the final analyses. We used logistic regression models in order to identify factors associated with vaccination status in the final sample. Complex sample analyses were used to account for the study design.

RESULTS

In the studied population 79.6% of the children were vaccinated against measles. After adjusting for potential confounders, regression models showed that the increasing age of the child (AOR 1.07, 95% CI: 1.03-1.12), secondary education of the mothers (AOR 3.38, 95% CI: 1.17-9.76) and attendance at postnatal check-up within two months after birth (AOR 2.71, 95% CI: 1.17-6.30) were significantly associated with the vaccination status of the child.

CONCLUSIONS

The measles vaccination coverage among the children was lower than the recommended percentage. The study confirmed the importance of maternal education and attending postnatal care visits. However, the study also showed that there might be potential risks for future measles outbreaks because of delayed vaccinations and a large group of children with an unknown vaccination status.

[Modeling of iodine consumption with industrial processed foods made with iodized salt in the adults and pregnant in Armenia and Moldova]

In recent years, significant progress has been made at the global level in eliminating of iodine deficiency. However, until recently, there has been a gap in methods for estimating iodine intake with industrially processed foods (IPF) produced with iodized salt (IS). The aim of this work was to study the iodine consumption with IPF and kitchen salt by the adult population and pregnant women in Armenia and Moldova. Material and methods. For modeling iodine consumption, a special matrix based on MS Excel spreadsheets was used, into which data on the average per capita daily consumption of the main IPF, salt content in IPF, the share of IPF produced with IS in the total volume of their consumption, percentage of households using IS, and the iodine content in salt according to the national standard were entered. Results and discussion. The estimated average daily salt consumption per capita of the adult population of Armenia was 10.6 g. Due to the use of IS in 93% of households and in the production of 82% of bakery products, 7% of cheese, 83% of meat products, 44% of canned vegetables and 5% of pasta, iodine intake in adults was 149% of the recommended daily allowance (RDA). Bakery products and iodized kitchen salt were the main sources of iodine (66 and 70% of the RDA respectively), and the share of other IPF did not exceed 13%. In Moldova, salt consumption was 11.9 g per day. Due to the use of IS for the production of 50% bakery products, 12% of canned vegetables and 20% of pasta, iodine consumption in adults in Moldova amounted to 74% of RDA almost entirely due to bakery products and kitchen salt (37 and 35% of the RDA respectively). The median urinary iodine concentration indicated adequate iodine intake in both countries and was significantly higher in Armenia (242 μg/L) than in Moldova (136 μg/L). A planned 30% reduction in salt intake may lead to an inadequate reduction in iodine intake in pregnant women. Conclusion. Adequate iodine intake among the adult population of Armenia and Moldova is ensured mainly through the use of IS in households and in the production of bakery products.

Development and Evaluation of a Tele-Education Program for Neonatal ICU Nurses in Armenia

PURPOSE

Neonatal mortality currently accounts for more than 60% of all infant mortality in Armenia. The majority of health professionals in Neonatal Intensive Care Units (NICU) however, have had no specialized training in neonatology. Local and global agencies have emphasized the need for improvement in the education and skills of NICU health professionals. The objective of this study was to design, implement, and evaluate an innovative tele-education program for NICU nurses in Armenia.

DESIGN AND METHODS

Seven online tele-education courses were designed on various neonatal nursing topics using Final Cut Pro and translated professionally to Armenian. The videos were uploaded to YouTube. All NICU nurses employed in two hospitals (n = 35) in Yerevan, Armenia, completed a diagnostic pretest, course viewing, a posttest, and a satisfaction survey for each topic. A difference in knowledge was defined as the number of correct test answers obtained before and after the course. Participant satisfaction was measured using a Likert scale.

RESULTS

The combined average for completed pre-tests for all courses was 45% and 71% for post-tests, which was statistically significant for each course (p < 0.05). A majority of the nurses either agreed or strongly agreed with all of the satisfaction parameters of the course.

CONCLUSIONS

These results support a tele-education model for effectively providing continuing education to NICU nurses in Armenia. A similar platform could be used to establish nationwide certification programs for neonatal nurses.

PRACTICE IMPLICATIONS

Tele-education technology can be used effectively by nursing educators working in global health as part of international learning collaboratives.

Surveillance Metrics of SARS-CoV-2 Transmission in Central Asia: Longitudinal Trend Analysis

BACKGROUND

SARS-CoV-2, the virus that caused the global COVID-19 pandemic, has severely impacted Central Asia; in spring 2020, high numbers of cases and deaths were reported in this region. The second wave of the COVID-19 pandemic is currently breaching the borders of Central Asia. Public health surveillance is necessary to inform policy and guide leaders; however, existing surveillance explains past transmissions while obscuring shifts in the pandemic, increases in infection rates, and the persistence of the transmission of COVID-19.

OBJECTIVE

The goal of this study is to provide enhanced surveillance metrics for SARS-CoV-2 transmission that account for weekly shifts in the pandemic, including speed, acceleration, jerk, and persistence, to better understand the risk of explosive growth in each country and which countries are managing the pandemic successfully.

METHODS

Using a longitudinal trend analysis study design, we extracted 60 days of COVID-19-related data from public health registries. We used an empirical difference equation to measure the daily number of cases in the Central Asia region as a function of the prior number of cases, level of testing, and weekly shift variables based on a dynamic panel model that was estimated using the generalized method of moments approach by implementing the Arellano-Bond estimator in R.

RESULTS

COVID-19 transmission rates were tracked for the weeks of September 30 to October 6 and October 7-13, 2020, in Central Asia. The region averaged 11,730 new cases per day for the first week and 14,514 for the second week. Infection rates increased across the region from 4.74 per 100,000 persons to 5.66. Russia and Turkey had the highest 7-day moving averages in the region, with 9836 and 1469, respectively, for the week of October 6 and 12,501 and 1603, respectively, for the week of October 13. Russia has the fourth highest speed in the region and continues to have positive acceleration, driving the negative trend for the entire region as the largest country by population. Armenia is experiencing explosive growth of COVID-19; its infection rate of 13.73 for the week of October 6 quickly jumped to 25.19, the highest in the region, the following week. The region overall is experiencing increases in its 7-day moving average of new cases, infection, rate, and speed, with continued positive acceleration and no sign of a reversal in sight.

CONCLUSIONS

The rapidly evolving COVID-19 pandemic requires novel dynamic surveillance metrics in addition to static metrics to effectively analyze the pandemic trajectory and control spread. Policy makers need to know the magnitude of transmission rates, how quickly they are accelerating, and how previous cases are impacting current caseload due to a lag effect. These metrics applied to Central Asia suggest that the region is trending negatively, primarily due to minimal restrictions in Russia.

Violation of the Global Ceasefire in Nagorno-Karabagh: A Viral Amplification of Aggression

On March 23, 2020, the United Nations (UN) made an "Appeal for a Global Ceasefire following the Outbreak of Coronavirus." Despite this appeal, the Nagorno-Karabagh war was instigated on September 27, 2020. This Guest Editorial frames the conflict in the context of the UN appeal and by introducing a figure that plots seven-day average coronavirus disease 2019 (COVID-19) cases overlaid with key inflection points to illustrate the clear impact that conflict has had on pandemic spread in Armenia. The conflict in Nagorno-Karabagh provides a timely, concise, and illustrative example of conflict and its impact on health. Finally, an argument is made that the ability to enforce the UN "Appeal for a Global Ceasefire" is essential to ensure global health and security.

Healthcare in transition in the Republic of Armenia: the evolution of emergency medical systems and directions forward

Armenia, an ex-Soviet Republic in transition since independence in 1991, has made remarkable strides in development. The crisis of prioritization that has plagued many post-Soviet republics in transition has meant differential growth in varied sectors in Armenia. Emergency systems is one of the sectors which is neglected in the current drive to modernize. The legacy of the Soviet Semashko system has left a void in specialized care including emergency care. This manuscript is a descriptive overview of the current state of emergency care in Armenia using in-depth key informant interviews and review of published and unpublished internal United States Agency for International Development (USAID) and Ministry of Health (MOH) documents as well as data from the Yerevan Municipal Ambulance Service and international agencies. The Republic of Artsakh is briefly discussed.

The development of emergency care systems is an extremely efficient way to provide care across many different conditions in many age groups. Conditions such as traumatic injuries, heart attacks, cardiac arrest, stroke, and respiratory failure are very time-dependent. Armenia has a decent emergency infrastructure in place and has the benefit of an educated and skilled physician workforce. The missing piece of the puzzle appears to be investment in graduate and post-graduate education in emergency care and development of hospital-based emergency care for stabilization of stroke, myocardial infarction, trauma, and sepsis as well as other acute conditions.

Feasibility and integration of an intensive emergency pediatric care curriculum in Armenia

Background

Emergency pediatric care curriculum (EPCC) was developed to address the need for pediatric rapid assessment and resuscitation skills among out-of-hospital emergency providers in Armenia. This study was designed to evaluate the effectiveness of EPCC in increasing physicians’ knowledge when instruction transitioned to local instructors. We hypothesize that (1) EPCC will have a positive impact on post-test knowledge, (2) this effect will be maintained when local trainers teach the course, and (3) curriculum will satisfy participants.

Methods

This is a quasi-experimental, pre-test/post-test study over a 4-year period from October 2014‑November 2017. Train-the-trainer model was used. Primary outcomes are immediate knowledge acquisition each year and comparison of knowledge acquisition between two cohorts based on North American vs local instructors. Descriptive statistics was used to summarize results. Pre-post change and differences across years were analyzed using repeated measures mixed models.

Results

Test scores improved from pretest mean of 51% (95% CI 49.6 to 53.0%) to post-test mean of 78% (95% CI 77.0 to 79.6%, p < 0.001). Average increase from pre- to post-test each year was 27% (95% CI 25.3 to 28.7%). Improvement was sustained when local instructors taught the course (p = 0.74). There was no difference in improvement when experience in critical care, EMS, and other specialties were compared (p = 0.23). Participants reported satisfaction and wanted the course repeated. In 2017, EPCC was integrated within the Emergency Medicine residency program in Armenia.

Discussion

This program was effective at impacting immediate knowledge as well as participant satisfaction and intentions to change practice. This knowledge acquisition and reported satisfaction remained constant even when the instruction was transitioned to the local instructors after 2 years. Through a partnership between the USA and Armenia, we provided OH-EPs in Armenia with an intensive educational experience to attain knowledge and skills necessary to manage acutely ill or injured children in the out-of-hospital setting.

Conclusions

EPCC resulted in significant improvement in knowledge and was well received by participants. This is a viable and sustainable model to train providers who have otherwise not had formal education in this field.

Frozen conflict in the midst of a global pandemic: potential impact on mental health in Armenian border communities

Armenia has been in a conflict with its neighbor, Azerbaijan, since 1988. Civilians in Tavush Province are regularly affected by ceasefire violations along the armed border with recent escalations further threatening the population's safety. In the midst of the COVID-19 pandemic, concerns regarding the mental health of border village residents in Armenia are prevalent. We present context-related factors of psychiatric illness, the prevalence of mental health disorders, and the state of mental health services in Armenia. We recommend directing greater attention towards the mental health status of civilians residing in conflict zones during the ongoing COVID-19 pandemic.

Characterization of Salmonella Isolates from Various Geographical Regions of the Caucasus and Their Susceptibility to Bacteriophages

Non-typhoidal Salmonella present a major threat to animal and human health as food-borne infectious agents. We characterized 91 bacterial isolates from Armenia and Georgia in detail, using a suite of assays including conventional microbiological methods, determining antimicrobial susceptibility profiles, matrix assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry, serotyping (using the White-Kauffmann-Le Minor scheme) and genotyping (repetitive element sequence-based PCR (rep-PCR)). No less than 61.5% of the isolates were shown to be multidrug-resistant. A new antimicrobial treatment strategy is urgently needed. Phage therapy, the therapeutic use of (bacterio-) phages, the bacterial viruses, to treat bacterial infections, is increasingly put forward as an additional tool for combatting antibiotic resistant infections. Therefore, we used this representative set of well-characterized Salmonella isolates to analyze the therapeutic potential of eleven single phages and selected phage cocktails from the bacteriophage collection of the Eliava Institute (Georgia). All isolates were shown to be susceptible to at least one of the tested phage clones or their combinations. In addition, genome sequencing of these phages revealed them as members of existing phage genera (Felixounavirus, Seunavirus, Viunavirus and Tequintavirus) and did not show genome-based counter indications towards their applicability against non-typhoidal Salmonella in a phage therapy or in an agro-food setting.

Continuing Medical Education and Continuing Professional Development in the Republic of Armenia: The Evolution of Legislative and Regulatory Frameworks Post Transition

The collapse of the Soviet Union in 1991 left many ex-republics in a financial and administrative crisis for the ensuing two decades. Previously centralised processes like recertification of doctors and healthcare workers and continuing medical education fell by the wayside. Continuing medical education and continuing professional development in Armenia have evolved through multiple phases from Soviet, to immediate, mid and late-transitional post-Soviet periods, to current modernising efforts. This manuscript describes the phases of evolution of continuing medical education chronologically and details the legislative and regulatory framework surrounding each stage of development. Armenia is currently implementing a credit system of continuing medical education with the aim to introduce and adopt new and efficient approaches in this field. Continuing education credits fall into three categories: didactic or theoretical knowledge, practical skills and self-education/self-development. To recertify, professionals must collect credits from all three groups with specified minimum amounts according to their degrees. Armenia’s guiding principle is to harmonise the continuing medical education and professional development model with internationally accepted criteria in order to contribute to the international mobility of healthcare workers and to provide for true on-going professional development and knowledge that will benefit our doctors, nurses and above all our patients.

Gaps in tuberculosis control in Armenia: How to improve the care system?

INTRODUCTION

Tuberculosis (TB) continues to be a global public health problem. People with weakened immune systems are more vulnerable to TB. It is one of the top 10 causes of death worldwide and is a leading cause of death for people living with HIV (PLWH). The aim of the current study was to perform programmatic data analysis of TB cases treated with the first-line drugs, registered in Armenia for the period of January 2017 - August 2018, and to identify gaps in TB care system in Armenia.

METHODOLOGY

A retrospective cohort study using programmatic data from National TB Program.

RESULTS

Overall treatment success rate for the period of study was 79%. HIV had impact only on "died" outcome with odds ratio (OR) of 20.9. More than a third (34%) of all HIV-positive patients died during TB treatment and 45% of patients who had non-Armenian citizenship were lost to follow-up during the treatment (OR = 3.3). Treatment duration for the 8% of all cases (mainly with brain or bone localization) was > 9 months and lasted up to 500 days.

CONCLUSIONS

Better collaboration and partial integration of TB and HIV services in Armenia is required. The access to care for non-Armenian citizens needs to be improved. The national TB treatment guideline needs to be updated based on scientific evidence. This study demonstrates that continuous analysis of the available data and tailoring of the system is required to address the needs of key populations and achieve universal care coverage.
