The dental proteome of Homo antecessor.

The phylogenetic relationships between hominins of the Early Pleistocene epoch in Eurasia, such as Homo antecessor, and hominins that appear later in the fossil record during the Middle Pleistocene epoch, such as Homo sapiens, are highly debated1-5. For the oldest remains, the molecular study of these relationships is hindered by the degradation of ancient DNA. However, recent research has demonstrated that the analysis of ancient proteins can address this challenge6-8. Here we present the dental enamel proteomes of H. antecessor from Atapuerca (Spain)9,10 and Homo erectus from Dmanisi (Georgia)1, two key fossil assemblages that have a central role in models of Pleistocene hominin morphology, dispersal and divergence. We provide evidence that H. antecessor is a close sister lineage to subsequent Middle and Late Pleistocene hominins, including modern humans, Neanderthals and Denisovans. This placement implies that the modern-like face of H. antecessor-that is, similar to that of modern humans-may have a considerably deep ancestry in the genus Homo, and that the cranial morphology of Neanderthals represents a derived form. By recovering AMELY-specific peptide sequences, we also conclude that the H. antecessor molar fragment from Atapuerca that we analysed belonged to a male individual. Finally, these H. antecessor and H. erectus fossils preserve evidence of enamel proteome phosphorylation and proteolytic digestion that occurred in vivo during tooth formation. Our results provide important insights into the evolutionary relationships between H. antecessor and other hominin groups, and pave the way for future studies using enamel proteomes to investigate hominin biology across the existence of the genus Homo.

Impact of cultural and genetic structure on food choices along the Silk Road.

The complex interplay between genetics, culture, and environment forms an individual's biology, influencing their behavior, choices, and health. However, to what extent information derived from this intertwined network could be quantitatively summarized to provide a glance at an individual's lifestyle is difficult to say. Here, we focused on dietary preferences as cultural proxies and genome-wide data of 543 individuals from six historical Silk Road countries: Georgia, Armenia, Azerbaijan, Uzbekistan, Kazakhstan, and Tajikistan. These lands favored the dispersal of innovations, foods, and DNA halfway across Eurasia, thus representing an ideal subject to explore interactions of cultural factors and genetic ancestry. We used discriminant analysis of principal components to infer cultural clusters, where mixed memberships are allowed. Five different clusters emerged. Of these, clusters 1 and 3, driven by aversion to pork and alcoholic beverages, mirrored genetic admixture patterns with the exception of Azerbaijan, which shares preferences supported by Islamic culture with Eastern countries. Cluster 3 was driven by protein-rich foods, whose preference was significantly related to steppe pastoralist ancestry. Sex and age were secondary clustering factors, with clusters formed by male and young individuals being related to alcohol preference and a reduced liking for vegetables. The soft clustering approach enabled us to model and summarize the individual's dietary information in short and informative vectors, which show meaningful interaction with other nondietary attributes of the studied individuals. Encoding other cultural variables would help summarize an individual's culture quantitatively, thus ultimately supporting its inclusion as a covariate in future association studies.

Drug-Resistant Tuberculosis, Georgia, Kazakhstan, Kyrgyzstan, Moldova, and Ukraine, 2017-2022.

In 2021, the World Health Organization recommended new extensively drug-resistant (XDR) and pre-XDR tuberculosis (TB) definitions. In a recent cohort of TB patients in Eastern Europe, we show that XDR TB as currently defined is associated with exceptionally poor treatment outcomes, considerably worse than for the former definition (31% vs. 54% treatment success).

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

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

Reductions in spice lead levels in the republic of Georgia: 2020-2022.

Spice adulteration using yellow lead chromate-based pigments has been documented as a growing global health concern. Spices from the Republic of Georgia with extremely high levels of lead, up to an order of magnitude higher than any other spices worldwide, have been implicated as sources of child lead poisoning. The objectives of this study were to 1) evaluate lead concentrations in spices sampled across the country of Georgia between 2020 and 2022, and 2) assess factors associated with spice adulteration, specifically the role of spice quality and regulatory enforcement. Spice samples were collected from 29 cities nationwide. The most populous cities were selected in each administrative region as well as those of importance to the spice supply chain. Sampling was carried out at the largest spice bazaars in each city. The regions of Adjara and Imereti were the focus of qualitative interviews conducted in 2021 with key businesspeople selling spices with very high and low levels of lead. The same cities and bazaars were visited at each of three sampling periods between 2020 and 2022. In total, 765 spice samples were collected. Lead concentrations in spices decreased over time, with a maximum of 14,233 µg/g in 2020 down to 36 µg/g in the final sampling round of 2022. A logistic regression determined that sampling round, region and spice type were associated with elevated lead in samples. Samples from Adjara and those containing marigold had the highest lead levels. Interviews with eighteen prominent spice vendors revealed difficulties sourcing sufficient quantities of high quality, brightly colored marigold, and concerns about adulteration. Interviews with two authorities from the National Food Authority highlighted the increased attention on regulating lead in spices since 2018. Continued monitoring and periodic regulatory enforcement may adequately disincentivize further adulteration with lead chromate in the spice industry in Georgia.

SARS-CoV-2 infection during pregnancy and the risk of adverse maternal outcomes in the Republic of Georgia: a national birth registry-based cohort study.

BACKGROUND: Georgia experienced an increase in maternal deaths (MD) during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, which warrants further investigation. This study aimed to assess associations between timing of SARS-CoV-2 infection during pregnancy and MD, post-delivery intensive care unit (ICU) admission, and caesarean section (CS) delivery. METHODS: We performed a national birth registry-based cohort study of pregnant women who had completed 22 weeks of gestation and delivered between February 28, 2020, and August 31, 2022. The data were linked to coronavirus disease 2019 (COVID-19) testing, vital, and immunization registries. Pregnant women were classified into three groups: confirmed SARS-CoV-2 infection from conception through 31 days before delivery; confirmed infection within 30 days before or at delivery; and women negative for SARS-CoV-2 infection or without any test results (reference group). Multivariable logistic regression was used to calculate the adjusted odds ratios (aORs) and 95% confidence intervals (CIs). RESULTS: Among 111,493 pregnant women, 16,751 had confirmed infection during pregnancy, and 7,332 were fully vaccinated against COVID-19 before delivery. Compared to the reference group, those with confirmed infection within 30 days before or at delivery experienced increased odds of MD (aOR: 43.11, 95% CI, 21.99-84.55), post-delivery ICU admission (aOR: 5.20, 95% CI, 4.05-6.67), and CS delivery (aOR: 1.11, 95% CI, 1.03-1.20). CONCLUSIONS: Pregnant women in Georgia with confirmed SARS-CoV-2 infection within 30 days before or at delivery experienced a considerably higher risk of MD and post-delivery ICU admission and a slightly higher risk for CS delivery. Additionally, the results highlighted that most pregnant women were not vaccinated against COVID-19. These findings should alert stakeholders that adherence to public health preventive measures needs to be improved.

Contact tracing in Austria, Georgia, Kyrgyzstan, Ukraine, and Kosovo† during the COVID-19 pandemic: response review and good practices.

BACKGROUND: During the COVID-19 pandemic, effective contact tracing was recognized as a crucial public health response to mitigate the spread of SARS-CoV-2 and reduce COVID-19-related morbidity and mortality, particularly before widespread vaccination. The World Health Organization (WHO) recommended implementing active surveillance strategies to trace and quarantine contacts of confirmed or suspected COVID-19 cases. METHODS: A detailed review and analysis of the COVID-19 contact tracing responses was conducted in five European countries and territories, between March 2021 and August 2022. The countries and territories were selected to ensure geographical representation across the WHO European Region and applied a mixed-methods approach of in-depth interviews with various stakeholders across different administrative levels to identify good practices in COVID-19 contact tracing. The interviews covered 12 themes, including methods and procedures for COVID-19 contact tracing, information technology, quality assurance and key performance indicators. RESULTS: The findings demonstrate that the policy approach, digitalization capabilities and implementation approach varied in the countries and territories and were dynamic throughout the pandemic. The analysis revealed that some practices were applicable across all countries and territories, while others were context-specific, catering to each country's and territory's unique needs. The study highlighted a need for all countries to institutionalize contact tracing as an essential function of existing health systems, to digitalize contact tracing practices and processes, and to build and retain contact tracing capacities for better pandemic preparedness. CONCLUSION: The lessons related to COVID-19 contact tracing should be utilized to strengthen future outbreak response operations as part of epidemic and pandemic preparedness.

Engaging stakeholders to level up COPD care in LMICs: lessons learned from the "Breathe Well" programme in Brazil, China, Georgia, and North Macedonia.

BACKGROUND: Effective stakeholder engagement in health research is increasingly being recognised and promoted as an important pathway to closing the gap between knowledge production and its use in health systems. However, little is known about its process and impacts, particularly in low-and middle-income countries. This opinion piece draws on the stakeholder engagement experiences from a global health research programme on Chronic Obstructive Pulmonary Disease (COPD) led by clinician researchers in Brazil, China, Georgia and North Macedonia, and presents the process, outcomes and lessons learned. MAIN BODY: Each country team was supported with an overarching engagement protocol and mentored to develop a tailored plan. Patient involvement in research was previously limited in all countries, requiring intensive efforts through personal communication, meetings, advisory groups and social media. Accredited training programmes were effective incentives for participation from healthcare providers; and aligning research findings with competing policy priorities enabled interest and dialogue with decision-makers. The COVID-19 pandemic severely limited possibilities for planned engagement, although remote methods were used where possible. Planned and persistent engagement contributed to shared knowledge and commitment to change, including raised patient and public awareness about COPD, improved skills and practice of healthcare providers, increased interest and support from clinical leaders, and dialogue for integrating COPD services into national policy and practice. CONCLUSION: Stakeholder engagement enabled relevant local actors to produce and utilise knowledge for small wins such as improving day-to-day practice and for long-term goals of equitable access to COPD care. For it to be successful and sustained, stakeholder engagement needs to be valued and integrated throughout the research and knowledge generation process, complete with dedicated resources, contextualised and flexible planning, and commitment.

Detection of carbapenemase producing Acinetobacter baumannii ST19 from Georgia and Ukraine carrying bla OXA-23, bla OXA-72, and/or bla NDM-5, December 2019 to June 2023.

In 2003-2023, amid 5,436 Acinetobacter baumannii isolates collected globally through the Multidrug-Resistant Organism Repository and Surveillance Network, 97 were ST19PAS, 34 of which carbapenem-resistant. Strains (n = 32) sampled after 2019 harboured either bla OXA-23, bla OXA-72, and/or bla NDM-5. Phylogenetic analysis of the 97 isolates and 11 publicly available ST19 genomes revealed three sub-lineages of carbapenemase-producing isolates from mainly Ukraine and Georgia, including an epidemic clone carrying all three carbapenemase genes. Infection control and global surveillance of carbapenem-resistant A. baumannii remain important.

Evaluating Health Care Professionals' Readiness for e-Health Adoption in the Context of the COVID-19 Pandemic: A Georgian Perspective.

Background: The COVID-19 pandemic has accelerated the adoption of Electronic health (e-Health), leveraging technologies such as telemedicine, electronic health records, artificial intelligence, and patient engagement platforms. This transformation underscores e-Health's role in providing efficient, patient-centered care. Our study explores health care professionals' readiness for these technologies, emphasizing the need for tailored education in this evolving landscape. Methods: In our study, conducted between February and March 2023, we administered a questionnaire-based survey to 500 staff members (82.4% female, 17.6% male) aged 25-70 from medical universities in Tbilisi, Georgia. The structured questionnaire covered topics such as computer literacy, telemedicine awareness, patient data security, and ethical considerations. We employed SPSS v21.0 for data analysis, encompassing descriptive statistics and thematic analysis of open-ended responses. Results: Our study included 500 participants categorized into five age groups. Notably, 31% considered themselves computer "experts," while 69% rated their skills as "intermediate" or "advanced." Furthermore, 85% used computers professionally, with 33% having practical computer training. Interestingly, 59% expressed interest in information technology training. Regarding e-Health, 15% believed it involves remote communication between health care professionals and patients, while 42% considered it "correct," and 37% "might be correct." Concerning its application in managing patients, opinions varied. In terms of e-Health's integration into Georgia's health care, responses ranged. Regarding patient data safety, participants exhibited diverse views. Finally, opinions on the necessity of informed consent for e-Health applications varied among participants. Conclusions: Our study explores health care professionals' readiness for e-Health adoption during the COVID-19 pandemic. It reveals varying computer literacy levels, a willingness to learn, differing views on e-Health applications, and mixed opinions on its integration into Georgian health care. These findings emphasize the need for clear e-Health terminology, education, tailored approaches, and a focus on data privacy and informed consent. Overall, e-Health's transformative role in modern health care is underscored.

ADVANCES IN MINIMALLY INVASIVE SURGERY FOR PECTUS EXCAVATUM: ENHANCING OUTCOMES AND PATIENT CARE.

Pectus excavatum, also called sunken chest, is the most common deformation of the sternum (90%). The deformation is caused by the depression of the sternum and costal cartilages, which causes reduction of the chest cavity and dysfunction of cardio-pulmonary systems in it. Sunken chest is more common in males than females, prevalence is 5/1. Most of the cases appear in the first year of life, however severity of the pathology is formed during puberty. Etiopathogenesis, genetic factors, and associated diseases of Pectus Excavatum are various and are still the subject of study. The manifestation of the disease is determined by the degree of chest deformation, which is calculated using the "Haller index". Providing that a high degree of deformation can lead to pathological functioning of the cardiovascular and respiratory systems. The treatment of this condition is an urgent, complex, and developing issue. The main method of treatment for sunken chest is surgical intervention; However, in cases of mild degrees of the mentioned deformation, different approaches are used. Our goal is to discuss contrasting treatment techniques and present our improved repairing technique for sunken chest, which is performed in Georgia.

THYROID CANCER AS A PUBLIC HEALTH CHALLENGE IN GEORGIA.

Thyroid cancer (TC) is the most common endocrine cancer. The increase in thyroid cancer incidence has been observed in both developed and developing countries in different Geographical and climate areas The share of thyroid cancer drastically increased during the last decades in Georgia and ranked as the second most prevalent cause of cancer among women. Although for addressing the burden of cancer, important steps were taken by the State during the last decades, the burden of this disease is still significant. The presented paper aims to provide an overview of the current burden of thyroid cancer in Georgia, delving into its risk factors. To explore the opinion of key stakeholders about the factors causing the increased trend of thyroid cancer in Georgia in-depth interviews were used. The study was conducted from March to August 2023 in the capital of Georgia - Tbilisi. Women and men who had thyroid cancer and survived, women and men who are suffering from thyroid cancer along with healthcare providers, policymakers, and national professional bodies were the respondents in this study. The guides for the in-depth interviews were prepared based on the literature review. Stakeholders agreed that the number of thyroid cancer cases has increased during the last decades. The concern that the prevalence and incidence of thyroid cancer is the highest in the world in Georgia and it is the second leading cause of cancer among women was also expressed by respondents. According to study findings, new diagnostic methods revealed more cases of thyroid cancer. Other respondents stated that the development of the cancer registry, and the improvement of the reporting system existing cases of this disease. The issue of over-diagnosis was also mentioned by the stakeholders, Almost all study participant patients are challenged by the post-operational period. Some of them had not gotten information on how to deal with this period. Several patients mentioned financial problems due to fee-for-service or co-payments. According to the study participants, the recent sharp increase in the incidence and prevalence of thyroid cancer cases might be associated with overdiagnosis and the lack of monitoring and unified diagnostic and treatment methods.

ERGONOMIC PRACTICE IN DENTAL CLINICS AND MUSCULOSKELETAL DISORDERS AMONG DENTISTS IN GEORGIA.

The dental profession is associated with occupational health problems. The working environment of a dentist is associated with ergonomic risk factors that can significantly reduce the dentist's working ability and even cause the termination of his/her professional activity. Numerous studies have been conducted in different countries (Sweden, Denmark, Germany, Poland, Australia, etc.) to assess the prevalence of musculoskeletal disorders in dentists, though no studies related to the principles of ergonomics in dentistry have been carried out in Georgia. The study aimed to assess the ergonomics of the working environment of dentists in Tbilisi (capital city of Georgia) clinics and to identify the prevalence of musculoskeletal disorders among them. An observational descriptive study was conducted in April-July 2023 in Tbilisi. A special questionnaire of 40 questions was designed based on international experience. The survey was conducted by random sampling in selected dental clinics. Dentists were asked to fill out the questionnaire during their free time between patient appointments. Those who agreed to participate were provided with electronic versions of the questionnaire. Five hundred dentists were invited to participate in the survey, of whom 314 (62.8%) agreed to fill out the questionnaire. A total of 291 fully completed questionnaires were used for the descriptive statistical analysis. Our study shows that in Tbilisi clinics dentists work on average for 5-6 days (48.8% - 6 days, 37.1% - 5 days) or 40-48 hours a week. A majority of respondents said their workplace met the requirements of ergonomics (it had a good lighting, the chair had a back, instruments could be easily reached), yet most of them rarely lean on the backrest, never or rarely use the hand rest method, and never or rarely do light physical exercise during breaks. The survey shows that 53.6% of dentists most frequently suffer from pain in the back, followed by pain in the neck (50.9%), shoulders (47.9%) and lower back (47.1%). Most of them said they had to work less because of the pain. Introduction of the principles of ergonomics in dental profession is vital for preventing occupational musculoskeletal disorders. It is important to provide continuing professional development programs and information booklets for dentists and thematic online webinars for the management of dental clinics in Georgia.

African Swine Fever Virus and Host Response: Transcriptome Profiling of the Georgia 2007/1 Strain and Porcine Macrophages.

African swine fever virus (ASFV) has a major global economic impact. With a case fatality in domestic pigs approaching 100%, it currently presents the largest threat to animal farming. Although genomic differences between attenuated and highly virulent ASFV strains have been identified, the molecular determinants for virulence at the level of gene expression have remained opaque. Here, we characterize the transcriptome of ASFV genotype II Georgia 2007/1 (GRG) during infection of the physiologically relevant host cells, porcine macrophages. In this study, we applied cap analysis gene expression sequencing (CAGE-seq) to map th0e 5' ends of viral mRNAs at 5 and 16 h postinfection. A bioinformatics analysis of the sequence context surrounding the transcription start sites (TSSs) enabled us to characterize the global early and late promoter landscape of GRG. We compared transcriptome maps of the GRG isolate and the lab-attenuated BA71V strain that highlighted GRG virulence-specific transcripts belonging to multigene families, including two predicted MGF 100 genes, I7L and I8L. In parallel, we monitored transcriptome changes in the infected host macrophage cells. Of the 9,384 macrophage genes studied, transcripts for 652 host genes were differentially regulated between 5 and 16 h postinfection compared with only 25 between uninfected cells and 5 h postinfection. NF-κB activated genes and lysosome components such as S100 were upregulated, and chemokines such as CCL24, CXCL2, CXCL5, and CXCL8 were downregulated. IMPORTANCE African swine fever virus (ASFV) causes hemorrhagic fever in domestic pigs, with case fatality rates approaching 100% and no approved vaccines or antivirals. The highly virulent ASFV Georgia 2007/1 strain (GRG) was the first isolated when ASFV spread from Africa to the Caucasus region in 2007, then spreading through Eastern Europe and, more recently, across Asia. We used an RNA-based next-generation sequencing technique called CAGE-seq to map the starts of viral genes across the GRG DNA genome. This has allowed us to investigate which viral genes are expressed during early or late stages of infection and how this is controlled, comparing their expression to the nonvirulent ASFV-BA71V strain to identify key genes that play a role in virulence. In parallel, we investigated how host cells respond to infection, which revealed how the ASFV suppresses components of the host immune response to ultimately win the arms race against its porcine host.

Analysis of the illicit tobacco market in Georgia in response to fiscal and non-fiscal tobacco control measures.

BACKGROUND: Georgian illicit cigarette consumption was 1.5% in 2017. In 2018, a new tobacco control law took effect followed by a substantial cigarette excise tax increase in 2019. Research shows these policies reduce tobacco consumption, but the tobacco industry argues they increase illicit trade. There is limited evidence on this, particularly from developing countries. METHODS: A panel household survey in Georgia obtained data over three waves: 2017 baseline, 2018 after the tobacco control law took effect and 2019 after taxes increased. A sample of 1578 smokers (and quitters in later waves) from five regions reported their tobacco use and were asked to present a cigarette pack in their possession. These were examined for tax stamps and health warnings to establish legality. FINDINGS: There was no evidence of an increase in illicit cigarette consumption in Tbilisi, Kutaisi, Akhaltsikhe or Gori in any wave. In Zugdidi, near the Russian-occupied Abkhazia, illicit cigarette consumption was increasing even prior to the tax increase, reaching 30.9% by wave 3. A country-wide shift occurred from manufactured cigarettes to roll-your-own tobacco (whose tax remained unchanged) between waves 2 and 3. CONCLUSION: No evidence of a country-wide increase in illicit cigarette trade was found after non-fiscal tobacco measures took effect and cigarette taxes increased. Relatively high illicit cigarette consumption in Zugdidi highlights the role of disputed territories and border administration in illicit cigarette supply. Substitution towards roll-your-own tobacco after manufactured cigarette taxes increased demonstrates the importance of equalising taxes on tobacco products to maximise public health benefits.

The impact of COVID-19-related restrictions on pregnancy and abortion rates in the Republic of Georgia.

BACKGROUND: The Republic of Georgia implemented COVID-19-related restrictions starting on 31 March 2020, when it imposed a 1-month strict lockdown, after which the country continued with some form of restrictions for 1 year. These restrictions created barriers to healthcare access, affected healthcare services, caused severe economic degradation, and changed reproductive behavior. The aim of this study was to explore the impact of COVID-19-related restrictions on pregnancy and abortion rates in Georgia. METHODS: Information on pregnancy, abortion, and related variables was extracted from the Georgian Birth Registry from January 2018 through April 2022. The final study sample included 232,594 pregnancies and 86,729 abortions. We used interrupted time series analysis to study the impact of COVID-19-related restrictions. RESULTS: There were slightly decreasing trends in pregnancy and abortion rates in the pre-pandemic period (1 January 2018-31 March 2020). During the 1-month strict lockdown (1 April-30 April 2020), pregnancy and abortion rates decreased in all investigated age groups. There were no substantial differences in pregnancy or abortion rates in the pandemic period (for pregnancies: 1 April 2020-30 June 2021; for abortions: 1 April 2020-30 April 2022) compared to the pre-pandemic period. The precision of all estimates suggested that both small increases and decreases in pregnancy and abortion rates are reasonably compatible with our data. CONCLUSIONS: Despite the 1-year-long COVID-19-related restrictions, our results did not indicate substantial long-term changes in pregnancy or abortion rates during the study period for any age group. This may indicate that the restrictions did not substantially influence access to contraception, abortion services, or reproductive behavior.

Insights from a national survey in 2021 and from modelling on progress towards hepatitis C virus elimination in the country of Georgia since 2015.

BackgroundBetween May 2015 and February 2022, 77,168 hepatitis C virus (HCV)-infected people in Georgia have been treated through an HCV elimination programme. To project the programme's long-term impacts, an HCV infection model was initially developed, based on data from surveys among people who inject drugs and a national serosurvey in 2015.AimAccounting for follow-up surveys in 2021, we validate and update projections of HCV infection prevalence and incidence.MethodWe assessed the initial model projections' accuracy for overall prevalence, by age, sex, and among people who ever injected drugs, compared with 2021 serosurvey data. We used 2021 results to weight model fits and to recalculate the national programme's impact leading up to March 2022 on HCV infection incidence rates. Cases and deaths averted were estimated. The impact of reduced treatment rates during the COVID-19 pandemic was assessed.ResultsThe original model overpredicted adult (≥ 18 years old) chronic HCV infection prevalence for 2021 (2.7%; 95% credible interval (CrI): 1.9-3.5%) compared with a 2021 serosurvey (1.8%; 95% confidence interval (CI): 1.3-2.4%). Weighted model projections estimated a 60% decrease in HCV infection incidence by March 2022, with an absolute incidence of 66 (95% CrI: 34-131) per 100,000 person-years (overall population). Between May 2015 and March 2022, 9,186 (95% CrI: 5,396-16,720) infections and 842 (95% CrI: 489-1,324) deaths were averted. The COVID-19 pandemic resulted in 13,344 (95% CrI: 13,236-13,437) fewer treatments and 438 (95% CrI: 223-744) fewer averted infections by March 2022.ConclusionResults support the programme's high effectiveness. At current treatment rate (406/month), 90% reductions in prevalence and incidence in Georgia are achievable by 2030.

Knowledge, attitudes, and beliefs of cardiovascular disease prevention in young adults in the country of Georgia.

INTRODUCTION: Cardiovascular disease (CVD) accounts for 46% of all mortality in the country of Georgia (former Soviet Union). Young adults in that country have not been studied regarding CVD and a need exists to understand lifestyle modifications to promote cardiovascular health. DESIGN: An interpretive description qualitative design was used to explore Georgian young adults' knowledge, attitudes, and beliefs of CVD preventative practices and life experiences. METHODS: A convenience sample of 19 ethnic Georgian participants (18-40 years old) who were fluent in either English, Georgian, or Russian from a local private university was used. Semi-structured interviews were conducted via video conferencing utilizing an interpreter. RESULTS: Four themes were identified: (1) CVD and risk factor knowledge, (2) prevention attitudes, beliefs, and gender differences, (3) health literacy influences, and (4) culture and societal impacts. CVD knowledge was limited and influenced by health literacy and the current healthcare system in Georgia. CONCLUSION: Cultural and societal gender norms influence cardiovascular health behaviors. CLINICAL IMPLICATIONS: Georgian nurses can play a key role in CVD education and screening for young adults in Georgia.

Costs of syringe vending machines in Tbilisi, Georgia.

BACKGROUND: Syringe vending machines (SVM) can improve access to sterile injecting equipment, but they have not been widely implemented or evaluated. We evaluate the cost of SVM installed between July 2019-December 2020 in Tbilisi, Georgia. METHODS: The SVM were stocked with several kit types, including injecting equipment for opioid or stimulant users, naloxone, male and female condoms, and pregnancy tests. We gathered financial data from the project to estimate fixed (staff time, start-up costs, equipment, running costs, and consumables) and variable (harm reduction kits) costs. We calculated the full cost of the SVM intervention, cost per user, cost per additional syringe accessed by SVM users, and cost per kit distributed (2020 Euros). RESULTS: SVM access cards were issued to 1132 users, and 29,238 kits were distributed through SVM, total cost €204,358. Staff costs were 51% of total, consumable costs 28%, equipment 10%, and start up, recurrent costs, and overheads 5% or less each. Opioid and stimulant kits were most accessed (35% and 32% of total). Cost per user was €66/year, and cost per transaction €7, of which €5 fixed costs and €2 variable. If monthly transactions increased from the average of 1622/month to highest monthly usage (4714), fixed costs per transaction would decrease to < €1. It cost €0.55 per additional syringe accessed/user/month. CONCLUSIONS: This study provides evidence for governments about the cost of SVM, a novel harm reduction intervention. This is particularly relevant where Global Fund is withdrawing and harm reduction services need to be incorporated into national budgets.

Evaluation of barriers to cervical cancer screening in Georgia.

OBJECTIVES: The Cervical Cancer (CC) Screening Programme in Georgia provides insufficient coverage of the target population. The aim of the study is to identify the barriers to cervical cancer screening for women in Georgia in order to plan and implement adequate measures to increase the screening effectiveness. METHODS: The study is based on the results of a survey of 582 women aged 25-60 years (mean age 42.11 + 12.17). Respondents were selected in out-patient clinics. The questionnaire included questions related to the place of residence, ethnicity, religion, marital status, education, employment, cervical cancer awareness and screening, screening participation practices, and barriers to participation. RESULTS: The following factors reliably increase the chance of participating in the screening: residing in Tbilisi, OR = 1.84 (95% CI: 1.10-3.07); higher education, OR = 1.87 (95% CI: 1.09-3.19); being employed as a nurse, OR = 3.42 (95% CI: 1.49-7.85); receiving screening-related information from medical staff, OR = 2.43 (95% CI: 1.42-4.15); and from television, OR = 2.57 (95% CI: 1.47-4.50). The chance of participating in the screening is reduced due to incomplete secondary education, OR = 0.10 (95% CI: 0.01-0.77); single marital status, OR = 0.49 (95% CI: 0.28-0.87); employment in public service, OR = 0.39 (95% CI: 0.17-0.89); and receiving screening-related information from friends, OR = 0.26 (95% CI: 0.09-0.77). Women with higher education are undoubtedly more informed about screening, screening procedures and free programmes than those without higher education. The common barrier to participation in the screening was "fear of the manipulation-related pain" but the most frequent answer was "I'm afraid that the test will detect cancer (36.3%)." Women with a lower level of education are more likely to believe that "Pap testing is appropriate for the women who have active sexual life", and/or "have multiple sexual partners", and/or "have children," and "it is not necessary if a woman has no complaints". CONCLUSION: Screening participation among women in Georgia depends on screening availability, formal education and awareness of CC, sources of information, and employment type.
