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).

Impact and cost-effectiveness of the 6-month BPaLM regimen for rifampicin-resistant tuberculosis in Moldova: A mathematical modeling analysis.

BACKGROUND: Emerging evidence suggests that shortened, simplified treatment regimens for rifampicin-resistant tuberculosis (RR-TB) can achieve comparable end-of-treatment (EOT) outcomes to longer regimens. We compared a 6-month regimen containing bedaquiline, pretomanid, linezolid, and moxifloxacin (BPaLM) to a standard of care strategy using a 9- or 18-month regimen depending on whether fluoroquinolone resistance (FQ-R) was detected on drug susceptibility testing (DST). METHODS AND FINDINGS: The primary objective was to determine whether 6 months of BPaLM is a cost-effective treatment strategy for RR-TB. We used genomic and demographic data to parameterize a mathematical model estimating long-term health outcomes measured in quality-adjusted life years (QALYs) and lifetime costs in 2022 USD ($) for each treatment strategy for patients 15 years and older diagnosed with pulmonary RR-TB in Moldova, a country with a high burden of TB drug resistance. For each individual, we simulated the natural history of TB and associated treatment outcomes, as well as the process of acquiring resistance to each of 12 anti-TB drugs. Compared to the standard of care, 6 months of BPaLM was cost-effective. This strategy was estimated to reduce lifetime costs by $3,366 (95% UI: [1,465, 5,742] p < 0.001) per individual, with a nonsignificant change in QALYs (-0.06; 95% UI: [-0.49, 0.03] p = 0.790). For those stopping moxifloxacin under the BPaLM regimen, continuing with BPaL plus clofazimine (BPaLC) provided more QALYs at lower cost than continuing with BPaL alone. Strategies based on 6 months of BPaLM had at least a 93% chance of being cost-effective, so long as BPaLC was continued in the event of stopping moxifloxacin. BPaLM for 6 months also reduced the average time spent with TB resistant to amikacin, bedaquiline, clofazimine, cycloserine, moxifloxacin, and pyrazinamide, while it increased the average time spent with TB resistant to delamanid and pretomanid. Sensitivity analyses showed 6 months of BPaLM to be cost-effective across a broad range of values for the relative effectiveness of BPaLM, and the proportion of the cohort with FQ-R. Compared to the standard of care, 6 months of BPaLM would be expected to save Moldova's national TB program budget $7.1 million (95% UI: [1.3 million, 15.4 million] p = 0.002) over the 5-year period from implementation. Our analysis did not account for all possible interactions between specific drugs with regard to treatment outcomes, resistance acquisition, or the consequences of specific types of severe adverse events, nor did we model how the intervention may affect TB transmission dynamics. CONCLUSIONS: Compared to standard of care, longer regimens, the implementation of the 6-month BPaLM regimen could improve the cost-effectiveness of care for individuals diagnosed with RR-TB, particularly in settings with a high burden of drug-resistant TB. Further research may be warranted to explore the impact and cost-effectiveness of shorter RR-TB regimens across settings with varied drug-resistant TB burdens and national income levels.

Association between STAT4 gene polymorphism and susceptibility to pulmonary tuberculosis in the Moldavian population.

Signal transducer and activator of transcription 4 (STAT4) plays a crucial role in the host immune response against Mycobacterium tuberculosis. This study investigates the association between STAT4 gene polymorphisms and pulmonary tuberculosis (TB) risk in the Moldavian population. A total of 272 TB patients and 251 community-matched controls underwent screening for functional single-nucleotide polymorphisms (SNPs) rs897200 and rs7574865 in the STAT4 gene. The minor T allele and the TT/CT genotype of rs897200 demonstrated a significant association with reduced pulmonary TB risk (allelic model: adjusted OR = .74, p = .025; log-additive model: adjusted OR = .72, p = .02; and dominant model: adjusted OR = .65, p = .023), indicating a protective effect. Similar associations, characterized by an even more pronounced reduction in risk, were observed among females and late-onset TB patients (>44 years). No significant associations were found for rs7574865. In addition, a combined genotype analysis incorporating 43 SNPs from our previous studies revealed potential associations, such as STAT4 rs897200 CT with IFNG rs2430561 AA (adjusted OR = .36, p = .0025) and STAT4 rs897200 CT with TNFA rs1800629 GA (adjusted OR = .33, p = .0012). This study emphasizes the significant association of STAT4 rs897200 with pulmonary TB risk in the Moldavian population, underscoring its role in the disease development.

Hepatitis C Elimination in Moldova Is Feasible and Cost-Saving: A Modeling Study.

BACKGROUND: Moldova, an upper-middle-income country in Eastern Europe, is facing a high burden of hepatitis C virus (HCV). Our objective was to assist the National Agency of Public Health of Moldova in planning to achieve the World Health Organization's HCV elimination goals by 2030. METHODS: This study adapted a previously developed microsimulation model to simulate the HCV epidemic in Moldova from 2004 to 2050. Model outcomes included temporal trends in HCV infection, prevalence, mortality, and total cost of care, including screening and treatment. We evaluated scenarios that could eliminate HCV by 2030. RESULTS: Multiple strategies could lead to HCV elimination in Moldova by 2030. A realistic scenario of a 20% annual screening and 80% treatment rate would require 2.75 million individuals to be screened and 65 000 treated by 2030. Compared to 2015, this program will reduce HCV incidence by 98% and HCV-related deaths by 72% in 2030. Between 2022 and 2030, this strategy would cost $17.5 million for HCV screening and treatment. However, by 2050, the health system would save >$85 million compared to no investment in elimination efforts. CONCLUSIONS: HCV elimination in Moldova is feasible and can be cost saving, but requires resources to scale HCV screening and treatment.

Limited Nosocomial Transmission of Drug-Resistant Tuberculosis, Moldova.

Applying whole-genome-sequencing, we aimed to detect transmission events of multidrug-resistant/rifampin-resistant strains of Mycobacterium tuberculosis complex at a tuberculosis hospital in Chisinau, Moldova. We recorded ward, room, and bed information for each patient and monitored in-hospital transfers over 1 year. Detailed molecular and patient surveillance revealed only 2 nosocomial transmission events.

Barriers to access adequate maternal care in Romania, Bulgaria, and Moldova: A cross-country comparison.

BACKGROUND: Eastern European health system indicators (e.g., number of health workers and care coverage) suggest well-resourced maternity care systems, but maternal health outcomes compare poorly with those in Western Europe. Often, poor maternal health outcomes are linked to inequities in accessing adequate maternal care. This study investigates access-related barriers (availability, appropriateness, affordability, approachability, and acceptability) to maternity care in Romania, Bulgaria, and Moldova. METHODS: This cross-country study (n = 7345) is based on an online survey where women who received maternity care and gave birth in 2015-2018 in Bulgaria (n = 4951), Romania (n = 2018), and Moldova (n = 376) provided information on their experiences with the care received. We used regression analysis to identify factors associated with accessing maternity care across the three countries. RESULTS: Results show high rates of cesarean births (CB) and a low number of antenatal and postnatal care visits. Informal payments and use of personal connections are common practices. Formal and informal out-of-pocket payments create a financial burden for women with health complications. Women who had health complications, those who gave birth by cesarean, and women who gave birth in a public facility and had fewer antenatal check-ups, were more likely to describe facing access-related barriers. CONCLUSIONS: This study identifies several barriers to high-quality maternity care in Romania, Bulgaria and Moldova. More attention should be paid to the appropriateness of care provided to women with complicated pregnancies, to those who have CBs, to women who give birth in public facilities, and to those who receive fewer antenatal care visits.

Modelling the dispersion of particulate matter (PM10) via wind erosion from opencast mining-Moldova Noua tailings ponds, Romania.

Historically, Romania is known as a mining site of mineral substances, including gold, silver, copper, lead, zin, uranium, manganese, salt, and coal, whereby their long periods of exploitation and extraction affected human health and the environment in various ways. In Moldova Noua southwest region of Romania, we investigated the environmental impacts of mining activities on air quality over 2021. We quantified PM10 emission rates through in situ monitoring, dispersion modelling, and horizontal and vertical fluxes. Statistical metrics, including the fraction within factor 2 (FAC2), mean bias (MB), mean gross error (MGE), normalized mean bias (NMB), normalized mean gross error (NMGE), coefficient of efficiency (COE), index of agreements (IOAs), and Taylor diagram signifying standards deviation (SD), root mean squared error (RMSE), and correlation coefficient (R), were used to evaluate the reliability of modelling results against observation. Results conclude that PM10 dispersion agrees with MB, MGE, NMB, NMGE, COE, IOA, and Taylor diagram and moderately with FAC2 metrics. PM10 hotspot was investigated in the vicinity of the tailings ponds of 115.5 µg m-3 annual mean, 563.7 µg m-3 daily mean, 63.3 µg m-2 s-1 annual horizontal flux, and 3.0 µg m-2 s-1 annual vertical flux. PM10 dispersion was identified to expand to Moldova Noua City and nearby country Serbia. Findings concluded that a windy air mass accumulation across the overburdened dumps and ponds causes the increase of PM10 in the air, resulting in the region's pollution. Therefore, results recommend adopting a strategic mitigation measure for residents, policymakers, stakeholders, and urban planners.

[Ukrainian war and its consequences Module "Mother and Child" of the Swiss Humanitarian Aid in Moldova]. / La guerre en Ukraine et ses conséquences. Le module « Mère-Enfant ¼ de l'aide humanitaire suisse en Moldavie.

As a result of the Ukraine conflict, more than 6.3 million refugees had to flee to neighbouring countries, among them the Republic of Moldova (RoM), triggering a social and humanitarian crisis. From our assessment of the general health situation and upon request of the RoM Ministry of Health, Swiss Humanitarian Aid module "mother and child" has been deployed to refugee transit centres to deliver primary health care of mothers and children. Due to the specific refugee population consisting mainly of mothers and children, the module showed to be very beneficial, extremely flexible and was highly appreciated. Simultaneously, strategic hospitals were revisited for contingency planning, but also in view of logistical support. We organized a "train the trainer" course together with the National Centre of pre-hospital assistance.

En raison du conflit en Ukraine, plus de 6,3 millions de réfugiés ont dû fuir vers les pays voisins, dont la Moldavie, déclenchant une crise sociale et humanitaire. Sur la base de notre évaluation et à la demande du ministère de la Santé de Moldavie, le module « Mère-Enfant ¼ de l'Aide humanitaire suisse a été déployé dans les centres de transit pour réfugiés afin de fournir des soins de santé primaires aux mères et aux enfants. La population spécifique de réfugiés étant composée principalement de mères et d'enfants, le module s'est avéré très bénéfique, flexible et très apprécié. Dans le même temps, les hôpitaux stratégiques ont été revisités pour la planification d'urgence, mais aussi pour le soutien logistique. Nous avons organisé des « formations des formateurs ¼ en collaboration avec le Centre national d'assistance préhospitalière.

Phylogeography and transmission of M. tuberculosis in Moldova: A prospective genomic analysis.

BACKGROUND: The incidence of multidrug-resistant tuberculosis (MDR-TB) remains critically high in countries of the former Soviet Union, where >20% of new cases and >50% of previously treated cases have resistance to rifampin and isoniazid. Transmission of resistant strains, as opposed to resistance selected through inadequate treatment of drug-susceptible tuberculosis (TB), is the main driver of incident MDR-TB in these countries. METHODS AND FINDINGS: We conducted a prospective, genomic analysis of all culture-positive TB cases diagnosed in 2018 and 2019 in the Republic of Moldova. We used phylogenetic methods to identify putative transmission clusters; spatial and demographic data were analyzed to further describe local transmission of Mycobacterium tuberculosis. Of 2,236 participants, 779 (36%) had MDR-TB, of whom 386 (50%) had never been treated previously for TB. Moreover, 92% of multidrug-resistant M. tuberculosis strains belonged to putative transmission clusters. Phylogenetic reconstruction identified 3 large clades that were comprised nearly uniformly of MDR-TB: 2 of these clades were of Beijing lineage, and 1 of Ural lineage, and each had additional distinct clade-specific second-line drug resistance mutations and geographic distributions. Spatial and temporal proximity between pairs of cases within a cluster was associated with greater genomic similarity. Our study lasted for only 2 years, a relatively short duration compared with the natural history of TB, and, thus, the ability to infer the full extent of transmission is limited. CONCLUSIONS: The MDR-TB epidemic in Moldova is associated with the local transmission of multiple M. tuberculosis strains, including distinct clades of highly drug-resistant M. tuberculosis with varying geographic distributions and drug resistance profiles. This study demonstrates the role of comprehensive genomic surveillance for understanding the transmission of M. tuberculosis and highlights the urgency of interventions to interrupt transmission of highly drug-resistant M. tuberculosis.

Moss Biomonitoring of Atmospheric Trace Element Pollution in the Republic of Moldova.

The moss biomonitoring technique was used for the assessment of air pollution in the Republic of Moldova, in the framework of the UNECE ICP Vegetation Programme. The content of 11 chemical elements (Al, V, Cr, Fe, Ni, Zn, As, Sb, Cd, Cu, and Pb) was determined by neutron activation analysis and atomic absorption spectrometry in samples collected in spring 2020. Distribution maps were built to identify the most polluted sites. The highest concentrations of elements in mosses were determined in the north-eastern, central, and western parts of the country. The main element associations were identified using factor analysis. Three factors were determined, of which one of mixed geogenic-anthropogenic origin and two of anthropogenic origin. A comparison of the data obtained in 2020 and 2015 showed a significant decrease in the concentrations of Cr, As, Sb, Cd, Pb, and Cu in 2020. The state of the environment was assessed using Contamination Factor and Pollution Load Index values, which characterized it as unpolluted to moderately polluted. Possible air pollution sources in the Republic of Moldova are resuspension of soil particles, agricultural practices, vehicles, industry, and thermal power plants.

Experience in radiological risk assessment of a surface waste disposal facility in Chisinau, Moldova.

The long-term condition and potential radiological consequences of legacy radioactive waste stored in a RADON-type of near-surface disposal facility outside the city of Chisinau is of concern to the central government and health protection authorities of the Republic of Moldova. A 'zero alternative scenario' risk assessment has been undertaken in order to evaluate the potential radiological impact on humans and the environment of the facility, were it to be left in its current state with no remediation. The results have been used as a basis for regulatory decision making regarding remediation and decommissioning of the legacy radioactive waste facility. The aim of this study was two-fold: first to demonstrate a complete radiological risk assessment of a real site using a combination of methodologies developed by the IAEA (ISAM and BIOMASS), the second to illustrate the current state-of-the-art in respect of extracting site-specific information from site-descriptive material. We illustrate the practicality of employing geographic information systems techniques on site-specific topographic data to identify relevant biosphere dose objects, thereby allowing customisation of the generic ISAM model framework to site-specific conditions. As a result, a simple method is suggested to bound activity concentrations in well water based on an understanding of water balance in the local catchment area in which the biosphere dose object is embedded. With conservative assumptions, estimated doses from the calculation cases of the design scenario remain lower than the IAEA's dose criteria and environmental screening values. However, the results also indicate that human intrusion activities after the institutional control period could lead to radiological exposures above the IAEA's criteria for a period up to 100 000 years. The long-lived radionuclide239Pu dominates doses for the on-site residence scenario. Remediation measures should be implemented were the waste to remain at its present place of disposal.

Safety and Efficacy of 48 Weeks REP 2139 or REP 2165, Tenofovir Disoproxil, and Pegylated Interferon Alfa-2a in Patients With Chronic HBV Infection Naïve to Nucleos(t)ide Therapy.

BACKGROUND & AIMS: Nucleic acid polymers (NAPs) inhibit assembly and secretion of hepatitis B virus (HBV) subviral particles. We performed an open-label, phase 2 study of the safety and efficacy of the NAPs REP 2139 or REP 2165 combined with tenofovir disoproxil fumarate (TDF) and pegylated interferon alfa-2a (pegIFN) in patients with chronic HBV infection who were negative for hepatitis B e antigen. METHODS: Following 24 weeks TDF therapy, 40 patients were randomly assigned to groups that received 48 weeks of experimental therapy (TDF + pegIFN + REP 2139-Mg or REP 2165-Mg) or 24 weeks of control therapy (TDF + pegIFN) followed by 48 weeks of experimental therapy. Patients were then followed for a treatment-free period of 48 weeks. Primary outcomes were the safety and tolerability of REP 2139-Mg or REP 2165-Mg in combination with TDF + pegIFN compared with TDF + pegIFN alone through the first 48 weeks of therapy and subsequently throughout 48 weeks of NAP-based combination therapy (treatment weeks 24-72 in the experimental group and weeks 48-96 in the control group). Secondary outcomes were reductions in hepatitis B surface antigen (HBsAg) in control and experimental groups over the first 48 weeks of the study and throughout 48 weeks of combination therapy and virologic control (HBsAg positive, HBV DNA below 2000 IU/mL, normal level of alanine aminotransferase) or functional cure (HBsAg below 0.05 IU/mL, HBV DNA target not detected, normal level of alanine aminotransferase) after removal of all therapy. RESULTS: Levels of HBsAg, anti-HBs, and HBV DNA did not differ significantly between the groups given REP 2139 vs REP 2165. PegIFN-induced thrombocytopenia (P = .299 vs controls) and neutropenia (P = .112 vs controls) were unaffected by NAPs (REP 2139 vs REP 2165). Increases in levels of transaminases were significantly more frequent (P < .001 vs controls) and greater (P = .002 vs controls) in the NAP groups (but did not produce symptoms), correlated with initial decrease in HBsAg, and normalized during therapy and follow-up. During the first 24 weeks of TDF and pegIFN administration, significantly higher proportions of patients in NAP groups had decreases in HBsAg to below 1 IU/mL (P < .001 vs control) and HBsAg seroconversion (P = .046 vs control). At the time patients completed the TDF + pegIFN + NAP regimen, HBsAg levels were 0.05 IU/mL or lower in 24/40 participants (all with seroconversion up to 233,055 mIU/mL). During 48 weeks of treatment-free follow-up, virologic control persisted in 13 of 40 participants (2 lost to follow-up after 24 weeks), whereas functional cure persisted in 14 of 40 participants (all completing 48 weeks of follow-up) with persistent HBsAg seroconversion. One participant had a viral rebound during follow-up with hepatic decompensation and was placed on TDF therapy. CONCLUSIONS: In a phase 2 randomized trial, we found that addition of NAPs to TDF + pegIFN did not alter tolerability and significantly increased rates of HBsAg loss and HBsAg seroconversion during therapy and functional cure after therapy. Clinicaltrials.gov no: NCT02565719.

Paleodemographic analysis of age at death for a population of Black Sea Scythians: An exploration by using Bayesian methods.

OBJECTIVES: Studies of the demography of past populations involving deterministic life tables can be criticized for ignoring the errors of estimation. Bayesian methods offer an alternative, by focusing on the uncertainty of the estimates, although their results are often sensitive to the choice of prior distributions. The aim of this study is to explore a range of Bayesian methods for estimating age at death for a population of nomadic warriors-Scythians from the Black Sea region. MATERIALS AND METHODS: In total, skeletons of 312 individuals (93 children and 219 adults) from Glinoe (Moldova), dated to the 5th-2nd century BCE, were examined. We unified the age categories corresponding to different aging methods, allowing an application of a probabilistic assessment of the age categorization. A hierarchical Bayesian multinomial-Dirichlet-Dirichlet model was applied, with a hypothetical, subjective reference population, a real reference population, and no reference. RESULTS: Stationary-population life expectancy was estimated as 27.7 years (95% CI: 25.1-30.3) for a newborn (e0 ), and 16.4 years (14.0-19.0) for 20-year-olds (e20 ), although with high uncertainty, and sensitive to the model specification. Slight differences in longevity between different social strata and between the Classical and Late chronological periods were found, although with high estimation errors. A more robust finding, confirming earlier studies, was a high probability of death in young adulthood, which could depend on Scythian lifestyle (conflicts, wars). DISCUSSION: Our study shows a way to overcome some limitations of broad age categorization by using the Bayesian approach with alternative model specifications, allowing to assess the impact of reference populations.

Provider attitudes towards a brief behavioral intervention for sexual health in Moldova.

BACKGROUND: Brief behavioral interventions are seen as an efficient way to improve knowledge, change behavior, and reduce provider stigma regarding sexual health. When grounded in evidence-based behavioral change techniques and delivered using Brief Sexuality-related Communication (BSC) tools, brief behavioral interventions can address client-driven sexual health goals in a single session with their provider. Evidence for the efficacy of brief interventions for creating gains in sexual health comes largely from resource rich settings, and there is a lack of knowledge of how brief interventions can be implemented in the more resource constrained environments of low- and middle-income countries. As a first step in developing a brief intervention to address sexual health issues in Moldova, this paper reports on qualitative data collected from Moldovan providers to understand their attitudes, willingness and perceived barriers to the brief intervention and its implementation. METHODS: Thirty-nine in-depth interviews (IDI) were conducted between February and March 2020, with health providers recruited from three primary health care institutions, two Youth Friendly Health Centers and counselors from three NGOs who work with key populations in Moldova, including health centers selected from two cites - the capital city, Chisinau and from the Comrat Region. The IDI addressed four domains of provider attitudes: 1) attitudes towards the intervention; 2) willingness and motivation to implement the intervention; 3) logistics of providing the intervention and 4) ability to implement the intervention. A coding analysis approach was applied to all interview transcripts. RESULTS: Providers largely reported being willing to be trained in and implement the brief intervention. Willingness to implement the intervention stemmed from two perceptions: that it would improve the ability of providers to talk with their clients about sex, and that vulnerable groups would benefit from these conversations. However, while there were generally positive attitudes towards the intervention, providers consistently reported structural barriers to their perceived ability to implement the intervention. CONCLUSIONS: While providers reported high levels of initial acceptance of a brief behavioral intervention, care is needed to ensure that brief interventions, and the training of providers on brief interventions, incorporate cultural attitudes and norms around sex, particularly in highly patriarchal settings, and provide opportunities for providers to practice the intervention in ways that address their assumptions and implicit biases.

Do catastrophic costs impact treatment outcomes in people with rifampicin-resistant tuberculosis in the Republic of Moldova?

The Republic of Moldova is among the 30 Rifampicin-Resistant and/or Multidrug-Resistant (RR/MDR) Tuberculosis (TB) high burden countries in the world. Despite free TB diagnostics and treatment, TB patients face substantial economic losses and this may impact overall treatment outcomes. We assessed if there is an association between TB-related catastrophic costs and TB treatment outcomes. We conducted a cohort study using data from patient records and a survey that quantified catastrophic costs among RR/MDR-TB affected households in the Republic of Moldova in 2016. We included adult patients (age ≥18 years) with RR/MDR-TB who had been in inpatient (intensive phase) or outpatient (continuous phase) treatment for at least 2 months. Unfavourable treatment outcome, such as failure, death or lost to follow-up, was the primary outcome variable. The definition of catastrophic TB-related costs followed the World Health Organisation (WHO) guidelines: costs due to TB ≥20% of annual household income. Log-binomial regression was used to assess association between the outcome and catastrophic TB-related costs adjusting for other socio-demographic, behavioural and clinical covariates.  In total 287 RR/MDR-TB patients (78% males, mean age 42 years) were included. Of them, 30% experienced catastrophic TB-related costs. Overall, one in five patients (21%) had unfavourable treatment outcome, such as treatment failure (5%), death (8%) or lost to follow-up (8%). The experience of catastrophic TB-related costs was not associated with unfavourable treatment outcome [adjusted relative risk (aRR)=0.88, 95% CI: 0.50-1.50]. Major factors independently associated with unfavourable TB treatment outcomes were poverty (aRR=2.07; 95% CI: 1.06-4.07), urban residence (aRR=1.99; 95% CI: 1.12-3.52) and positive HIV (Human Immunodeficiency Virus) status (aRR=2.61; 95% CI: 1.31-4.89). As a result, we failed to find an association between catastrophic costs and treatment outcomes of RR/MDR-TB patients in the Republic of Moldova. However, we found that patients from poor households and urban areas were twice more likely to achieve unfavourable TB treatment outcomes disregarding whether they experienced catastrophic costs or not. Also, TB/HIV patients and urban residents were identified as the most vulnerable groups with higher risk of unfavourable treatment outcome and TB-related costs.

Knowledge, opinions, and practices related to oral cancer prevention and oral mucosal examination among dentists in Moldova, Belarus and Armenia: a multi-country cross-sectional study.

INTRODUCTION: Moldova, Belarus, and Armenia are post-Soviet countries with a high rate of heavy smokers and a relatively high age-standardized incidence of oral cancer. However, to our knowledge, there is lack of available information on dentists' knowledge on prevention of oral cancer in the countries in question. Accordingly, this study aimed to assess the knowledge, opinions, and practices related to oral cancer prevention and oral mucosal examination among dentists in Moldova, Belarus, and Armenia. METHODS: This was a multi-country, cross-sectional study based on a self-administered questionnaire. A structured questionnaire was distributed to 3534 dentists (797 in Chisinau, Moldova, 1349 in Minsk, Belarus, and 1388 in Yerevan, Armenia). Dentists' knowledge about risk factors for oral cancer development and its clinical picture, current practices and opinions with regard to oral mucosal screening and oral cancer prevention, and their consistency to perform oral mucosal examination were assessed. A knowledge score ranging from 0 to 14 points was generated based on each dentist's answer to the questionnaire. RESULTS: A total of 1316 dentists responded, achieving an overall response rate of 37.2% (34.5% in Moldova; 52.3% in Belarus; 24.2% in Armenia). Most dentists in the three countries correctly identified tobacco (83.8-98.2%) and prior oral cancer lesions (84.0-96.3%) as risk factors for oral cancer. Most dentists correctly identified leukoplakia as a lesion with malignant potential (68.7% in Moldova; 88.5% in Belarus; 69.9% in Armenia), while erythroplakia was identified by much fewer in all three countries. Less than 52% of dentists identified the tongue, rim of tongue, and floor of mouth as the most common sites for oral cancer. The mean knowledge score for all countries combined was 7.5 ± 2.7. The most commonly reported barriers to perform oral mucosal examination were lack of training, knowledge, and experience. CONCLUSIONS: This study highlights the need for improved oral cancer-related education and training on oral mucosal examination for dentists in Moldova, Belarus, and Armenia. Such skills are essential to enhance oral cancer prevention and to improve the prognostic outcome by early detection.

Risk Factors for Cerebral Palsy in Moldova.

Background and Objectives: This is the first study assessing risk factors for cerebral palsy (CP) among children born in Moldova. The aim of this study was to identify and describe risk factors for cerebral palsy (CP) among children born in Moldova, which is one of the low-middle income countries in Europe. Materials and Methods: We identified 351 children with CP born during 2009 and 2010 in Moldova. Detailed information on 417 children without CP served as a reference group. Logistic regression analyses were applied to the calculate crude and adjusted odds ratios (OR) for CP with 95% confidence intervals (CI) in addition to attributable fraction (AF). Results: Among children with CP (40.5% girls), 26% had spastic unilateral, 54% bilateral, 13% dyskinetic, 5% ataxic and 2% unclassified CP. Significant risk factors for CP included maternal alcohol consumption during pregnancy (OR 1.7, p = 0.002), maternal hypertension (OR 2.0, p < 0.001), children born to mothers from the rural areas (OR 1.6, p < 0.001), maternal age ≥35 years (OR 0.6, p = 0.018), maternal epilepsy (OR 4.3, p < 0.001), breech delivery (OR 3.1, p = 0.001), home births (OR 6.3, p = 0.001), umbilical cord around neck (OR 2.2, p < 0.001), AVD (OR 3.1, p < 0.001), male gender (OR 1.3, p < 0.001), SGA (OR 1.3, p = 0.027), multiple gestations (OR 1.7, p < 0.001) and hyperbilirubinemia (OR 4.5, p < 0.001). Multivariable analyses showed that the AF of CP was 64% for rural residence (OR 2.8, p = 0.002), 87% for home birth (7.6, p = 0.005), 79% for pre-labor rupture of membrane (OR 4.9, p = 0.001), 66% for breech delivery (OR 2.9, p = 0.002) and 81% for hyperbilirubinemia (OR 5.4, p < 0.001). Conclusions: A combination of factors related to the mother, the delivery and the child were risk factors for CP in Moldova, many of them possibly avoidable. Improved pregnancy and maternity care would potentially reduce the risk of CP. A national CP registry in Moldova is suggested as an opportunity to follow up on these findings.

[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.

Video-observed therapy and medication adherence for tuberculosis patients: randomised controlled trial in Moldova.

INTRODUCTION: The effectiveness of video-observed therapy (VOT) for treating tuberculosis (TB) has not been measured in low- and middle-income countries (LMICs), where >95% of TB cases and deaths occur. In this study, we analyse the effectiveness and patient cost-difference of VOT compared to clinic-based directly observed therapy (DOT) in improving medication adherence in Moldova, a LMIC in Eastern Europe. METHODS: The study was a two-arm individually randomised trial with 197 TB patients (n=99 DOT control group; n=98 VOT treatment group; multidrug-resistant TB cases were excluded). The primary outcome was observed medication adherence, measured by the number of days that a patient failed to be observed adhering to medication for every 2-week period during the course of their treatment. RESULTS: VOT significantly decreased nonadherence by 4 days (95% CI 3.35-4.67 days, p<0.01) per 2-week period: 5.24 days missed per 2-week period for DOT and 1.29 days for VOT. VOT patients spent MDL 504 (∼EUR 25) (95% CI MDL 277-730, p<0.01) and 58 h (95% CI 48-68 h, p<0.01) less on their treatment. In addition, VOT increased self-reported satisfaction with treatment. We found no significant results pertaining to treatment success, patient wellbeing or patient employment status and some evidence of an increase in side-effects. DISCUSSION: In this trial, VOT increased observed medication adherence for TB patients in Moldova, a LMIC, when compared to clinic-based DOT. Additionally, VOT significantly reduced the time and money patients spent on their treatment.

Street food in Eastern Europe: a perspective from an urban environment in Moldova.

Street food is popular in Eastern Europe, but its diversity and nutritional value are unknown. This study aimed to characterise the street food environment in Chisinau, Moldova, including the vending sites and vendors, food availability and nutritional composition of foods and beverages. All street food vending sites (single point of sale) located in a 1-km buffer centred on the main public market were systematically selected (n 439; n 328 participants). Data on vending sites' characteristics (mobility, type of physical set-up and access to electricity), operating periods and food availability were collected. Samples of the most commonly available foods of unknown composition were collected (twenty-eight home-made and twenty-four industrial). Macronutrients, Na and K were quantified through chemical analysis. Fruits, beverages and food other than fruits were available in 2·5, 74·3 and 80·8 % of the vending sites, respectively. Among the latter, 66·4 % sold only industrial foods (e.g. pretzels, biscuits, wafers, chocolate and ice cream), 21·5 % only home-made (e.g. savoury and sweet pastries) and 12·1 % both. Home-made foods presented larger serving sizes and energy/serving (median kJ/serving: 1312·5 v. 670·3, P = 0·022); industrial foods were more energy-dense (median kJ/100 g: 1797·0 v. 1269·8, P = 0·002). High SFA, trans-fat and Na contents were found, reaching 10·9 g/serving, 1·4 g/serving and 773·7 mg/serving, respectively. Soft drinks and alcoholic beverages were available in 80·7 and 42·0 % of the vending sites selling beverages, respectively. Concluding, industrial snacks and home-made pastries high in Na and unhealthy fat were frequent in Chisinau. Prevention of diet-related diseases in Moldova may benefit from the improvement of the nutritional profile of street food.
