How likely are Eastern European and central Asian countries to achieve global NCD targets: multi-country analysis.

BACKGROUND: In Europe, mortality rates from noncommunicable diseases (NCDs) among persons 30-69 years of age ("NCD premature mortality rates") have declined significantly, except in twelve countries of Eastern Europe and Central Asia, namely Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine and Uzbekistan. Data on long-term trends in NCD mortality in these countries are limited. We analyzed NCD premature mortality rates, identified change points in NCD mortality trends and forecasted how likely countries are to achieve the global NCD targets, stratified by gender and NCD type. METHODS: We used the 1990-2019 Global Burden of Disease database to analyze NCD trends and identified country-specific change points by using piecewise linear regression. We assessed the likelihood of achieving the global targets for reducing NCD premature mortality rates among persons 30-69 years of age from four NCDs: cancers, diabetes, cardiovascular and chronic respiratory diseases. The global NCD targets are 25% reduction in mortality from 2010 to 2025 (WHO 25X25 target) and 33%-from 2015 to 2030 (SDG 3.4.1). We applied the analysis to both genders and four NCDs. RESULTS: Only Kazakhstan and Russia are likely to achieve the global NCD targets. For Kazakhstan, WHO 25X25 and SDG 3.4.1 global targets for mortality rates were 494.3 and 374.8 per 100,000 population respectively; the corresponding predicted values (PVs) were 360.6 [CI 260.1-461.1] and 245.1 [CI 113.4-376.8]. For Russia, WHO 25X25 and SDG 3.4.1 global targets were 560.5 and 442.8 per 100,000 population respectively; the corresponding PVs were 427.7 [CI 270.3-585.1] and 311.0 [CI 102.8-519.1]. Achieving NCD global targets is less likely for Kyrgyzstan, while it is unlikely for the rest of countries. Most countries had higher mortality rates and slower progress among men compared with women. The likelihood of achieving overall global NCD targets was mainly explained by reduction in cardiovascular mortality. CONCLUSIONS: In most Eastern Europe and Central Asia countries, progress towards achieving NCD global targets is slow, or there's a reverse trend. Further quantitative and qualitative research is needed to understand the underlying reasons. Separate indicators are needed to monitor trends for cancers, diabetes and chronic respiratory diseases.

Assessing the impacts of crop production on climate change: An in-depth analysis of long-term determinants and policy implications.

This research investigates the long-term determinants of carbon emissions in three diverse regions-Europe and Central Asia (ECA), Sub-Saharan Africa (SSA), and the Middle East and North Africa (MENA)-spanning 1990 to 2020. Utilizing advanced econometric models and analyses, including the Regularized Common Correlated Effects Estimator (rCCE), Common Correlated Effects Estimator (CCE), and Mean-Group (MG) approach, the study explores the intricate relationships between carbon emissions, crop production, emissions per agricultural production, energy consumption, renewable energy consumption, per capita GDP, and population. Region-specific nuances are uncovered, highlighting the varying dynamics: ECA exhibits intricate and non-significant relationships, SSA showcases significant effects of population dynamics and green technology adoption, and the MENA region reveals a nuanced interplay between emissions per agricultural production.The findings underscore the universal efficacy of green technology adoption for mitigation. Strategies for mitigating carbon emissions in the agricultural sector require diversified energy transition approaches, emphasizing efficiency enhancements, green technology adoption, and tailored population management strategies based on regional intricacies. Counterfactual simulations indicate the potential efficacy of strategic measures targeting crop production to reduce carbon emissions, while acknowledging the nuanced relationship between economic growth and emissions. Policymakers are urged to recognize the persistence in emission patterns, emphasizing the importance of targeted interventions to transition towards more sustainable trajectories. Overall, the research provides essential insights for crafting effective policies at both regional and global scales to address the complexities of climate change mitigation in the agricultural sector.

Ancient Genomes Reveal Unexpected Horse Domestication and Management Dynamics.

The horse was essential to past human societies but became a recreational animal during the twentieth century as the world became increasingly mechanized. As the author reviews here, recent studies of ancient genomes have revisited the understanding of horse domestication, from the very early stages to the most modern developments. They have uncovered several extinct lineages roaming the far ends of Eurasia some 4000 years ago. They have shown that the domestic horse has been significantly reshaped during the last millennium and experienced a sharp decline in genetic diversity within the last two centuries. At a time when no truly wild horses exist any longer, this calls for enhanced conservation in all endangered populations. These include the Przewalski's horse native to Mongolia, and the many local breeds side-lined by the modern agenda, but yet representing the living heritage of over five millennia of horse breeding.

Evidence for extensive hybridisation and past introgression events in feather grasses using genome-wide SNP genotyping.

BACKGROUND: The proper identification of feather grasses in nature is often limited due to phenotypic variability and high morphological similarity between many species. Among plausible factors influencing this issue are hybridisation and introgression recently detected in the genus. Nonetheless, to date, only a bounded set of taxa have been investigated using integrative taxonomy combining morphological and molecular data. Here, we report the first large-scale study on five feather grass species across several hybrid zones in Russia and Central Asia. In total, 302 specimens were sampled in the field and classified based on the current descriptions of these taxa. They were then genotyped with high density genome-wide markers and measured based on a set of morphological characters to delimitate species and assess levels of hybridisation and introgression. Moreover, we tested species for past introgression and estimated divergence times between them. RESULTS: Our findings demonstrated that 250 specimens represent five distinct species: S. baicalensis, S. capillata, S. glareosa, S. grandis and S. krylovii. The remaining 52 individuals provided evidence for extensive hybridisation between S. capillata and S. baicalensis, S. capillata and S. krylovii, S. baicalensis and S. krylovii, as well as to a lesser extent between S. grandis and S. krylovii, S. grandis and S. baicalensis. We detected past reticulation events between S. baicalensis, S. krylovii, S. grandis and inferred that diversification within species S. capillata, S. baicalensis, S. krylovii and S. grandis started ca. 130-96 kya. In addition, the assessment of genetic population structure revealed signs of contemporary gene flow between populations across species from the section Leiostipa, despite significant geographical distances between some of them. Lastly, we concluded that only 5 out of 52 hybrid taxa were properly identified solely based on morphology. CONCLUSIONS: Our results support the hypothesis that hybridisation is an important mechanism driving evolution in Stipa. As an outcome, this phenomenon complicates identification of hybrid taxa in the field using morphological characters alone. Thus, integrative taxonomy seems to be the only reliable way to properly resolve the phylogenetic issue of Stipa. Moreover, we believe that feather grasses may be a suitable genus to study hybridisation and introgression events in nature.

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.

Peer Reviewers in Central Asia: Publons Based Analysis.

BACKGROUND: The five Central Asian republics comprise of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. Their research and publication activities are gradually improving but there is limited data on how good their peer reviewing practices are. METHODS: We have use the Publons database to extract information on the reviewers registered including the number of verified review, Publons award winners, and top universities in the domain of peer reviewing. This has been analysed overall and country wise. RESULTS: Of 15,764 researchers registered on Publons, only 370 (11.7%) have verified records of peer-reviewing. There are 8 Publons award winners. There is great heterogeneity in the number of active reviewers across the five countries. Kazakhstan and Uzbekistan account for more than 90% of verified reviewers. Only Kazakhstan has more than 100 active reviewers and 6 Publons award recipients. Amongst the top 20 reviewers from Central Asia, half of them are from the Nazarbayev University, Nur-Sultan, Kazakhstan. Three countries have less than 10 universities registered on Publons. CONCLUSION: Central Asia has a good number of peer reviewers on Publons though only a minority of researchers are involved in peer reviewing. However, the heterogeneity between the nations can be best dealt with by promoting awareness and international networking including e-learning and mentoring programs.

Chronic hepatitis B infection and the risk of gestational diabetes: a cross-sectional study.

OBJECTIVE: An estimated two billion people worldwide live with hepatitis B virus (HBV) infection. Many of these are women of reproductive age. Studies that have examined pregnancy outcomes in women living with HBV have reported conflicting results in relation to the incidence of gestational diabetes (GDM). The aim of this study is to examine if gestational diabetes is more common in women with chronic HBV residing in a non-Asian country. DESIGN: Cross-sectional study. SETTING: Victoria, Australia. POPULATION: All singleton births between 2009 and 2017. METHODS: Poisson regression was performed to determine whether gestational diabetes is more common in women with HBV than in women without HBV taking into account other risk factors such as maternal age, body mass index (BMI), parity and country of birth. MAIN OUTCOME MEASURE: Gestational diabetes diagnosis in women with chronic HBV infection. RESULTS: For women with HBV, the unadjusted incidence risk ratio for GDM was 1.75 (95% CI 1.6-1.9). After adjusting for region of birth, BMI, parity, age and smoking, the adjusted incidence risk ratio was 1.2 (95% CI 1.1-1.3). The highest incidence (37.1%) of GDM was in women with HBV and a BMI of >40. CONCLUSIONS: The findings from this study confirm an association between HBV and GDM. TWEETABLE ABSTRACT: HBV is associated with GDM with an incidence risk ratio for GDM of 1.75 (95% CI 1.6-1.9).

Height and life satisfaction: Evidence from 27 nations.

OBJECTIVES: To evaluate the effect of height on life satisfaction. METHODS: We use data from a recent multi-country survey that was conducted in 27 nations. RESULTS: Our main finding is that height does have a strong positive effect on life satisfaction. These findings remain positive and significant when we use a comprehensive set of well-known covariates of life-satisfaction at both the individual and country levels. These findings also remain robust to alternative statistical specifications. CONCLUSIONS: From a theoretical standpoint, our findings suggest that height is important in explaining life-satisfaction independent of other well-known determinants. From a methodological standpoint, the findings of this study highlight the need to explicitly control for the effect of heights in studies on subjective well-being, happiness, and life-satisfaction.

Training of psychiatrists in Eastern Europe: problems and solutions.

The analysis of the training of mental health professionals in WPA Zone 10 was performed based on a comparison of data of a specifically designed questionnaire comprising 29 questions on undergraduate education, 34 questions on postgraduate training, and six questions on training of general practitioners to work in the field of mental health. The project involved National Associations of psychiatrists of Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Russian Federation, Uzbekistan, and Ukraine. This comparison provides an opportunity to identify ways to improve psychiatric training in Eastern Europe.

Exploring the spatial-temporal characteristics of the aerosol optical depth (AOD) in Central Asia based on the moderate resolution imaging spectroradiometer (MODIS).

Central Asia has become a key node of the belt and road corridor. It is located in arid and semi-arid climate regions, and it is a region where the contribution of global aerosols of sand and dust is continuous. However, few studies have been conducted on the Central Asian aerosol optical depth. Therefore, this paper relied on the belt and road sustainable development dataset to analyze the spatial-temporal variations in the AOD in Central Asia and provide spatial-temporal characteristics of the AOD for environmental services. We analyzed the spatial and temporal variation in the aerosol optical depth (AOD) in Central Asia by using MODIS/AQUA C6 MYD08_M3 images from 2008 to 2017. The results showed that (1) the annual average AOD in Central Asia in the past decade varied from 0.183 to 0.232, which indicated a slow decline starting in 2014. The percentage of average annual decline was approximately 0.18%, and the regular distinct revealed the distribution characteristics of AOD. In different years, the Central Asian region exhibited the similar monthly change characteristics: from July to December, the AOD decreased, and from December to February, it increased. In different seasons, the Central Asian region exhibited the different seasonal change characteristics: the AOD value was higher in the spring and summer. The mean values in the spring, summer, autumn, and winter were 0.273, 0.240, 0.155, and 0.183, respectively, and the standard deviations were 0.036, 0.038, 0.025, and 0.048, respectively. (3) Based on spatial distribution characteristics, the Tarim Basin, Aral Sea region, and Ebinur Lake area were high value areas, and Kazakhstan was a low value area. The AOD of the surrounding area of the Aral Sea had increased in the last 5 years, while that of Kazakhstan, Uzbekistan, and Turkmenistan had decreased. The AOD of the Taklamakan area exhibited an inter-annual change. Sand dust aerosols were the largest contributors to the AOD in the Taklamakan area. The rising trend of the AOD in the Aral Sea area was clear, with an average annual increase of 0.234%, and the contribution of salt dust aerosols to the AOD increased. The average annual AOD in the Ebinur Lake area remained stable.

Insights into matrilineal genetic structure, differentiation and ancestry of Armenians based on complete mitogenome data.

Distinctive peculiarities of Armenians such as their millennia-long genetic isolation and strong national identity attract a keen interest while studying the demographic history of the West Asia. Here, to examine their fine-scale matrilineal genetic structure, ancestry and relationships with neighboring populations, we analyzed 536 complete mitogenomes (141 of which are novel) from 8 geographically different Armenian populations, covering the whole stretch of historical Armenia. The observed patterns highlight a remarkable degree of matrilineal genetic heterogeneity and weak population structuring of Armenians. Moreover, our phylogeographic analysis reveals common ancestries for some mtDNA lineages shared by West Asians, Transcaucasians, Europeans, Central Asians and Armenians. About third of the mtDNA subhaplogroups found in Armenian gene pool might be considered as Armenian-specific, as these are virtually absent elsewhere in Europe, West Asia and Transcaucasia. Coalescence ages of most of these lineages do not exceed 3.1 kya and coincide well with the population size growth started around 1.8-2.8 kya detectable only in the Bayesian Skyline Plots based on the Armenian-specific mtDNA haplotypes.

Population uptake and effectiveness of test-and-treat antiretroviral therapy guidelines for preventing the global spread of HIV: an ecological cross-national analysis.

OBJECTIVES: Although the benefits of adopting test-and-treat antiretroviral therapy (ART) guidelines that recommend initiation of ART regardless of CD4 cell counts have been demonstrated at the individual level, there is uncertainty about how this translates to the population level. Here, we explored whether adopting ART guidelines recommending earlier treatment initiation improves population ART access and viral suppression and reduces overall disease transmission. METHODS: Data on ART initiation guidelines and treatment coverage, viral suppression, and HIV incidence from 37 European and Central Asian countries were collected from the European Centre for Disease Prevention and Control and the Global HIV Policy Watch and HIV 90-90-90 Watch databases. We used multivariate linear regression models to quantify the association of ART initiation guidelines with population ART access, viral suppression, and HIV incidence, adjusting for potential confounding factors. RESULTS: Test-and-treat policies were associated with 15.2 percentage points (pp) [95% confidence interval (CI) 0.8-29.6 pp; P = 0.039] greater treatment coverage (proportion of HIV-positive people on ART) compared with countries with ART initiation at CD4 cell counts ≤ 350 cells/µL. The presence of test-and-treat policies was associated with 15.8 pp (95% CI 2.4-29.1 pp; P = 0.023) higher viral suppression rates (people on ART virally suppressed) compared with countries with treatment initiation at CD4 counts ≤ 350 cells/µL. ART initiation at CD4 counts ≤ 500 cells/µL did not significantly improve ART coverage compared to initiation at CD4 counts ≤ 350 cells/µL but achieved similar degrees of viral suppression as test-and-treat. CONCLUSIONS: Test-and-treat was found to be associated with substantial improvements in population-level access to ART and viral suppression, further strengthening evidence that rapid initiation of treatment will help curb the spread of HIV.

Forensic features and genetic structure of 23 autosomal STRs in Artux Turkic-speaking population residing in southwestern Xinjiang Uyghur Autonomous Region.

Autosomal short tandem repeats (STRs) are viewed as the gold standard in forensic individual identification and parentage testing. The Huaxia Platinum System contains 23 autosomal markers along with rs2032678 (Yindel) and amelogenin. Here, we genotyped 23-STRs in the southwestern Xinjiang Uyghur residing in the Artux Region and assessed the allele frequency and forensic statistical parameters. All investigated STRs are in conformity with the Hardy-Weinberg equilibrium with an effective combined power of discrimination (0.99999999999999999999999999992) and cumulative probability of exclusion (0.9999999997) in the Artux Uyghur population. Population comparisons among 54 worldwide populations via PCA and MDS indicate that the Artux Uyghur population has a close genetic relationship with geographically distinct Uyghurs and Kazakh groups than other East Asians or Eurasians. Genetic ancestry component dissection among 2198 individuals from Sinitic, Turkic, and Tibeto-Burman language groups further demonstrates the genetic homogeneity within the Turkic language family and apparent genetic heterogeneity among other language groups.

Multilocus Genotypes of the Wheat Leaf Rust Fungus Puccinia triticina in Worldwide Regions Indicate Past and Current Long-Distance Migration.

Many plant pathogenic fungi have a global distribution across diverse ecological zones and agricultural production systems. Puccinia triticina, the wheat leaf rust fungus, is a major pathogen in many wheat production areas of the world. The objective of this research was to determine the genetic relatedness of P. triticina in different worldwide regions. A total of 831 single-uredinial isolates collected from 11 regions were characterized for multilocus genotype at 23 simple sequence repeat loci and for virulence to 20 lines of wheat with single genes for leaf rust resistance. A total of 424 multilocus genotypes and 497 virulence phenotypes were found. All populations had high heterozygosity and significant correlation between virulence and molecular variation, which indicated clonal reproduction. The populations from North America and South America, Central Asia and Russia, and the Middle East and Europe were closely related for multilocus genotypes and many individual isolates from other continental regions were closely related. Twenty-seven multilocus genotypes were found in more than one continental region, and 13 of these had isolates with identical virulence phenotypes. The wide geographic distribution of identical and highly related multilocus genotypes of P. triticina indicated past and more recent migration events facilitated by the spread of clonally produced urediniospores.

Regional Overview on Maternal and Child Nutrition and Examples of Nutrition Governance and Policy Responses: Europe, Central Asia and Eastern Mediterranean Regions.

The Eastern Mediterranean Regions and Europe and Central Asia Regions are facing an epidemiological and nutrition transition, especially among vulnerable groups including mothers, children and adolescents. This has led to a double burden of malnutrition (DBM). Poor infant and young child feeding (IYCF), poor dietary diversity, excessive consumption of energy dense unhealthy foods, a growing obesogenic environment for children, including aggressive marketing of unhealthy foods for children, and reduced physical activity are among the main causes. In addition, several countries in the region lack the nutrition governance capacity to respond effectively to the DBM. This article reviews the context and provides a set of conclusions in which countries are called to reduce the marketing of unhealthy foods for children, enforce the fortification of staple foods with micronutrients to reduce micronutrient deficiencies and improve IYCF, including breastfeeding in the region. Also, the call is strong for cross-border multi-sectoral efforts to address the DBM in these regions.

Challenges and solutions for instituting an efficient maintenance program for laboratory equipment in Central Asian, and developing world, countries.

We review the current state of quality assurance in laboratories of the five Central Asia Republics (CARs), focusing on laboratory equipment, and compare quality assurance approaches with CLSI standards. The laboratories of the CARs faced exceptional challenges including highly-structured laboratory systems that retain centralized and outmoded Soviet-era approaches to quality assurance, considerably jeopardizing the validity of laboratory tests. The relative isolation of the CARs, based on geography and almost exclusive use of the Russian language, further hamper change. CARs must make high-level government decisions to widely implement quality assurance programs within their laboratory systems, within which approaches to the management of laboratory equipment will be a prominent part.

Risk of Invasive Cervical Cancer Among Immigrants in Ontario, Canada.

BACKGROUND: The risk of invasive cervical cancer (ICC) varies throughout the world. We aimed to compare the risk of this invasive disease among immigrants arriving in Ontario with that of the general female population of Ontario. METHODS: We used an exposure-control matched design. We identified females from the Immigration, Refugees, and Citizenship Canada (IRCC) database with arrival in Ontario, and whose first eligibility for the Ontario Health Insurance Plan according to its Registered Persons Database fell between July 1, 1991, and June 30, 2008, at age 20 years or older, and matched two female controls on year of birth. We identified cases of ICC between the index date and December 31, 2014. Crude rates and relative rates of ICC were calculated. Multivariable extended Cox regression models were then implemented. RESULTS: The crude rate of ICC was 0.032 per 100 000 person-years for immigrants and 0.037 for controls. Immigrants who were born in certain countries showed a higher risk of ICC; Russia had a relative rate of 1.736 compared with a relative rate of 0.221 among those born in Iran. Among immigrants, the age-adjusted HR was 0.76 (95% CI 0.63-0.92) after 10 years of residency when compared with controls. Immigrants aged 20 to 39 years had a lower risk of ICC compared with controls of equivalent age, and immigrants aged ≥40 years had a higher risk of ICC. CONCLUSIONS: The risk of ICC among immigrants in Ontario varies by age, country of birth, and time since immigration.

Tuberculosis incidence among migrants according to migrant status: a cohort study, Denmark, 1993 to 2015.

BackgroundMigrants account for the majority of tuberculosis (TB) cases in low-incidence countries in western Europe. TB incidence among migrants might be influenced by patterns of migration, but this is not well understood.AimTo investigate differences in TB risk across migrant groups according to migrant status and region of origin.MethodsThis prospective cohort study included migrants ≥ 18 years of age who obtained residency in Denmark between 1 January 1993 and 31 December 2015, matched 1:6 to Danish-born individuals. Migrants were grouped according to legal status of residency and region of origin. Incidence rates (IR) and incidence rate ratios (IRR) were estimated by Poisson regression.ResultsThe cohort included 142,314 migrants. Migrants had significantly higher TB incidence (IR: 120/100,000 person-years (PY); 95% confidence interval (CI): 115-126) than Danish-born individuals (IR: 4/100,000 PY; 95% CI: 3-4). The IRR was significantly higher in all migrant groups compared with Danish-born (p < 0.01). A particularly higher risk was seen among family-reunified to refugees (IRR: 61.8; 95% CI: 52.7-72.4), quota refugees (IRR: 46.0; 95% CI: 36.6-57.6) and former asylum seekers (IRR: 45.3; 95% CI: 40.2-51.1), whereas lower risk was seen among family-reunified to Danish/Nordic citizens (IRR 15.8; 95% CI: 13.6-18.4) and family-reunified to immigrants (IRR: 16.9; 95% CI: 13.5-21.3).DiscussionAll migrants had higher TB risk compared with the Danish-born population. While screening programmes focus mostly on asylum seekers, other migrant groups with high risk of TB are missed. Awareness of TB risk in all high-risk groups should be strengthened and screening programmes should be optimised.

Pediatric Celiac Disease in Central and East Asia: Current Knowledge and Prevalence.

The current prevalence of pediatric Celiac Disease (CD) is estimated to be around 1% in the general population, worldwide. However, according to the geographic area, a great variability of CD prevalence has been described. Whereas a number of studies are available from Europe, North and South America, Australia, South-West Asia, and North Africa, the knowledge and awareness of CD in large parts of the remaining world areas is definitively poor. In several countries of Central and East Asia, the consumption of wheat is consistent and/or has significantly increased in recent decades, and CD is supposed to be underdiagnosed in children. In this mini-review, we aimed to summarize the current knowledge about the prevalence of pediatric CD in Central and East Asia, paying attention to the HLA-DQ immunogenetic background as well. Indeed, CD is likely not to be as uncommon as previously or currently thought in countries like Russia, Kazakhstan, and China, in addition to India, where pediatric CD has been clearly showed to be quite prevalent. Therefore, there is an urgent need for population-based studies on the prevalence of CD in those countries, especially in children, in order to increase the awareness of this disease and to improve the diagnostic strategy in these areas.
