Trends in Gastric Cancer Mortality in Montenegro, 1990-2018: Joinpoint Regression.

INTRODUCTION: Gastric cancer (GC) remains a significant global public health problem, despite the decreasing trends in GC mortality rates in the last 5 decades. Our study aimed to examine the pattern of GC mortality in Montenegro between 1990 and 2018 and to contribute to the future by designing a national long-term strategy for the control and prevention of GC. METHODS: Gastric cancer mortality data in Montenegro from 1990 to 2018 were collected. Mortality rates were age-standardized to the World Standard Population for estimating both the overall and gender-specific trends. The joinpoint regression model was used to assess GC mortality and identified significant changes in the linear time trend. Linear and Poisson regressions were also applied for additional trend analyses. RESULTS: Joinpoint regression reveals a statistically significant decrease in the age-standardized rate for the overall level, on average by 1.4% per year (AAPC [95% IP] = -1.4 [-2.4 to -0.4]; p = 0.007), which was due to a decrease in the age-standardized rate in men with an average annual change of -1.8% (AAPC [95% IP] = -1.8 [-2.9 to -0.6]; p = 0.003), while in women the rates were stable (p = 0.565). The results for age groups indicate that a decline was registered at the overall level, and among men, as a consequence of the trend of decreasing age-specific rates for the age group 55-64 on average annually by 2% among men (AAPC [95% IP] = -2 [-3.8 to -0.1]; p = 0.035), and for the overall level (AAPC [95% IP] = -2 [-3.7 to -0.3]; p = 0.026). CONCLUSION: Our findings indicate a noteworthy decline in age-standardized overall GC mortality rates among men in Montenegro, while rates for women have remained constant. National strategies to further reduce mortality rates for GC are necessary.

Health policy developments in the Western Balkan Countries 2000-19: towards European Health and Health Care Policies.

BACKGROUND: Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia and Serbia have committed to becoming European Union (EU) member states. This, among others, implies that candidate/potential candidate states adopt legally authorized EU policies, including health. The study aims to identify the main country-specific health policy areas critical to the EU accession health policy dimension and present the change in associated selected health indicators from 2000 to 2019. METHODS: The study draws on published reports and analyses of official statistics over time and cross-country. Health care policy adherence to the European Commission's recommended country-specific health actions was classified into five health policy areas: financing, payment, organization, regulation and persuasion. Key health policy areas for Western Balkan countries (WBCs) were identified. Health progress or lack thereof in catching up to the EU15 population health, health expenditure and the number of health professionals are measured. RESULTS: The European Commission prioritized financing and regulation for all WBCs in the five policy areas. Nine of the 18 analyzed selected health indicators showed divergence, and the other nine converged towards the EU15 averages. WBCs continue to face diverse public health challenges in improving life expectancy at birth, death rates caused by circulatory system diseases, malignant neoplasms, traffic accidents, psychoactive substance use, tuberculosis incidence, tobacco smoking prevalence and public-sector health expenditure. CONCLUSIONS: By 2019, there is limited evidence of WBCs catching up to the average EU15 health levels and health care policies. Closer attention towards EU health and health care policies would be favourable.

Trends in oesophageal cancer mortality in Montenegro, 1990-2018.

BACKGROUND: Oesophageal cancer (OC) is a significant public health issue, despite the decreasing trends in OC mortality rates observed globally in the past decades. The objective of our study is to analyze the pattern of OC mortality in Montenegro between 1990 and 2018 and contribute to the development of a national long-term strategy for the prevention and control of this malignancy. METHODS: The data on OC death cases in Montenegro between 1990 and 2018 were collected. The mortality rates were standardized according to the World Standard Population. The Joinpoint, Linear and Poisson regressions were applied to analyze the OC mortality trend. RESULTS: Joinpoint regression analysis showed an increase in death rates for men and the overall level which were not statistically significant. However, the number of cases increases significantly with an average annual percentage change (AAPC) increase of 2.6% for the overall level [AAPC (95% CI)=2.6 (1.0-4.2); P = 0.002] at the expense of the increase in men, which on average was 2.6% annually [AAPC (95%CI) = 2.6 (1.2-4.1); P = 0.001]. The age groups 55-64 and 65-74 have the highest percentage of deaths cases from OC with 30.6% and 31.4%, respectively. CONCLUSION: Montenegro has witnessed a recent increase in the number of deaths from OC, although the mortality rates remain stable. National strategies to further reduce mortality rates for OC are necessary. Individuals aged 55-64 and 65-74 need specific attention during the ongoing monitoring of this cancer.

Evaluation of Risk Factors for the Occurrence of Limb Fractures in Children Due to Unintentional Injury in Podgorica, Montenegro, Mediterranean.

Background and Objectives: Limb injuries in childhood are very common, with most of them being unintentional and often accompanied by soft tissue injuries. The aim of our study was to determine the risk factors that contribute to the occurrence of limb fractures as the most common type of accidental injury to children in our conditions. Materials and Methods: This study was designed as a prospective clinical analysis of predictive factors with a "nested" case-control study. It included all patients under the age of 18 who were diagnosed with unintentional limb injury and limb fracture due to accidental injury, at the Clinical Center of Montenegro, Podgorica, in the period of 7 January 2020-30 June 2021. Results: The gender of the child and the occurrence of the fracture are not related, and a statistically significant relationship was found between the occurrence of the fracture and the place of residence, the child's age, body mass index (BMI), the affected limb, the method of injury, and the mental state of the parents of the injured child, as well as their economic status. It was proved that the older the child was, the lower the chance of injury, while multivariate analysis proved that BMI could be a predictor of accidental fracture. The most common method of accidental limb fractures in children was a fall from a height. Conclusions: The analysis of factors that influence the occurrence of children's injuries is of great importance for public health. Such and similar research can enable a better understanding of the factors that influence accidental injuries, and therefore influence the prevention of these injuries by organizing various educational materials at the primary healthcare level or at the school level, for both children and parents.

Measles outbreak, Montenegro January-July 2018: Lessons learned.

In 2017, the Regional Verification Commission for Measles and Rubella Elimination (RVC) of the World Health Organization confirmed that measles elimination was sustained in Montenegro, and the previous endemic transmission remained interrupted. However, the RVC was extremely concerned over the continuing low vaccination coverage reported for this country. In this study, we describe the most recent measles epidemic in Montenegro using the epidemiological data collected from January 1 to July 31, 2018. The outbreak is largely attributable to a dangerous accumulation of susceptible subjects across the country and represents a high-risk factor for re-establishing endemic transmission in the Balkan area. This study showed how a vaccine-preventable communicable disease outbreak can have a dramatic impact and severe consequences on regional public health system performance in terms of the sanitary spending point of view. A detailed update is provided on the epidemiological situation in this Central European area, not available until now.

Effectiveness of tax policy changes in Montenegro: smoking behaviour by socio-economic status.

BACKGROUND: The main goal of this study was to examine the responsiveness of smoking prevalence and cigarette consumption to price and income changes by income groups and the effectiveness of tax policy changes to reduce cigarette consumption in Montenegro. DATA AND METHODS: A two-part model was applied to estimate smoking participation, smoking intensity price and income elasticity. The first part of the model applies logit regression, while the second uses Deaton's model to improve the validity and objectivity of conditional (smoking intensity) elasticity results. A generalised linear model (GLM) was applied to verify robustness. The reason for this is that Deaton's model is commonly used in the analysis of Household Budget Survey (HBS) data, especially when households do not report the market price. Moreover, using this model, it is possible to capture the shading of quality to price change. The analysis used HBS data (2006-2017). RESULTS: The estimates indicate that tobacco pricing policies had a much higher impact on smoking prevalence in the low-income group (price elasticity of -0.595) relative to the high-income group (price elasticity of -0.344). The same conclusion could be drawn for the smoking intensity elasticity: the high-income group was the least affected by changes in price (price elasticity of -0.258). At the same time, the most affected was the low-income group, with price elasticity of -0.424. Poorer households spent a larger share of their budget on cigarettes. The simulation results confirm that increases in the specific excise taxes of 58.3% on tobacco would reduce total cigarette consumption by 11.25% while increasing the collection of government revenue by 8.07%. CONCLUSION: Smoking prevalence and consumption are very responsive to price and income changes, with considerable differences in elasticities between income groups. The taxation policy has a positive impact on changing patterns of consumption and public revenues across each income group. Low-income and middle-income households would benefit the most, while on the other hand, the highest revenue collection was generated from the wealthiest group. Our results align with results obtained so far for other low-income and middle-income countries. This paper contributes to the analysis of the smoking prevalence and cigarette consumption responsiveness to price and income changes, which was conducted for the first time in Montenegro.

Prevalence and clinical implications of the HPV16 infection in oral cancer in Montenegro - Evidence to support the immunization program.

Oral squamous cell carcinoma (OSCC) makes 85-95% of all malignances in the oral cavity. Increasing evidence shows that the Human Papillomaviruses (HPVs) are preferentially associated with some oropharyngeal and OSCCs, namely the genotype 16. The aim of the present study was to determine the prevalence and clinical implications of HPV16 infection in oral squamous cell carcinoma in population of Montenegro.This study included 60 patients with OSCC (localized on the lower lip, tongue or/and floor of the mouth), surgically treated at the Clinical Centre of Montenegro from 2012 to 2018. Surgically obtained formalin-fixed and paraffin-embedded specimens were used for histopathological analysis and HPV16 genome detection using standard Polymerase Chain Reaction (primers for detection of E6 gene). Each individual was further followed up for the period of three years and for different clinico-pathological characteristics, including disease free interval (DFI).The prevalence of HPV16 infection in OSCCs was 23.3% and the infection was significantly more common in female patients (P = 0.038). No significant correlation was detectable between HPV16 infection and the patients' age (P = 0.302), tumor site (P = 0.125), tumor grade (P = 0.363) and disease stage (P = 0.995). Observing the total sample the DFI was not significantly different for HPV16-positive versus HPV16-negative patients (P = 0.427), but a gender-based difference in DFI was observed, with the significantly shorter DFI (Log Rank test, P = 0.003) in HPV16 positive female patients compared to male patients (P = 0.003).The results obtained in this study provide scientific evidence for the development of national HPV vaccination program in Montenegro.

Optimal outcome factors in maternity and newborn care for inpatient (hospital maternity ward-HMW) and outpatient deliveries (outhospital maternity clinics -OMC).

BACKGROUND AND OBJECTIVES: The aim of the study was to use the United States Optimality Index (OI-US) to assess the feasibility of its application in making decisions for more optimal methods of delivery and for more optimal postpartum and neonatal outcomes. Numerous worldwide associations support the option of women giving birth at maternity outpatient clinics and also at home. What ought to be met is the assessments of requirements and what could be characterized as the birth potential constitute the basis for making the right decision regarding childbirth. MATERIALS AND METHODS: The study is based on a prospective follow-up of pregnant women and new mothers (100 participants) who were monitored and gave birth at the hospital maternity ward (HMW) and pregnant women and new mothers (100 participants) who were monitored and gave birth at the outhospital maternity clinics (OMC). Selected patients were classified according to the criteria of low and medium-risk and each of the parameters of the OI and the total OI were compared. RESULTS: The results of this study confirm the benefits of intrapartum and neonatal outcome, when delivery was carried out in an outpatient setting. The median OI of intrapartum components was significantly higher in the outpatient setting compared to the hospital maternity ward (97 range from 24 to 100 vs 91 range from 3 to 100). The median OI of neonatal components was significantly higher in the outpatient compared to the inpatient delivery. (99 range from 97 to 100 vs 96 range from 74 to 100). Certain components from the intrapartum and neonatal period highly contribute to the significantly better total OI in the outpatient conditions in relation to hospital conditions. CONCLUSION: Outpatient care and delivery provide multiple benefits for both the mother and the newborn.

A new tool for identifying risk of repeated intimate partner violence adjusted for the population of Montenegro: a cohort study.

Current estimates suggest that approximately 20% of women and 11% of men have been victims of intimate partner violence. Risk identification tools for repeated domestic violence currently exist and have typically been designed by police and judicial authorities, based on the criminal history of the perpetrator. A follow-up cohort study of 238 cases of intimate partner violence (judicially processed and officially judged as DV according to Montenegrin Criminal Act) was conducted by reviewing randomly selected court files. The results showed that certain perpetrator characteristics (unemployment, lack of regret, other violent criminal history, and history of being beaten by a family member) and victim characteristics (nonqualified education and predictions of future harm) were associated with reassault. Relationship characteristics such as different ethnicity, poor socioeconomic status, difference in incomes, living in a rental property, alcohol and drug use, and unprocessed previous history of physical violence were also associated with repeated violence. A risk identification tool for repeated intimate violence was computed based on the significant variables, with a sensitivity of 85% and a specificity of 89%. This study demonstrates a new tool for repeated intimate partner violence prediction in patriarchal societies, widespread in Eastern Europe and the Middle East. The majority of factors associated with reassault in this sample have been shown to be predictive for repeated intimate partner violence in previous studies. The applicability of our tool in egalitarian societies should be investigated in order to see whether the combination of these factors is universal or specific to patriarchal societies.

Poverty and other correlates of obesity and underweight among 7-year-olds from Croatia and Montenegro.

OBJECTIVES: This study aimed at investigating poverty and other correlates of childhood underweight and obesity in two urban regions with lower (Podgorica, Montenegro) and higher economic development (Osijek, Croatia). STUDY DESIGN: Comparative study. METHODS: A comparative study was conducted on 693 children (52% boys), aged 7 years old (224 from Podgorica and 469 from Osijek). Parents completed the study-specific questionnaire on relevant factors for children's nutritional status. We measured children's height and weight and calculated their body mass index (BMI). International Obesity Task Force cut-off values of BMI were used to assess children's nutritional status. Subjective social position was assessed by the Mac Arthur scale. RESULTS: There were more underweight children in Osijek compared with Podgorica, both among boys (5.5% vs. 1.6%) and girls (6.9% vs. 1.0%). Obesity was more frequent in Podgorica than Osijek, both among boys (11.3% vs. 5.9%) and girls (10.0% vs. 4.3%). However, poverty in two cities diminished observed differences in children's nutritional status. The odds for child underweight decreased by 12.2%, while the odds for obesity increased by 3.6% per each paternal BMI unit. The frequency of child obesity was lowered per each step higher on the Mac Arthur scale and with breastfeeding by 23.2% and 68.0%, respectively. CONCLUSIONS: We show that a higher economic development is related to less obese children but more underweight children. However, poverty seems to impact nutritionally all children equally, regardless of the regional economic development. Paternal and not maternal BMI is relevant for both extremes in children's nutritional status. Breastfeeding and higher social position independently protect from child obesity.

HPV TYPING AS A SCREENING PROGRAM FOR PREVENTION AND EARLY DETECTION OF CERVICAL CANCER IN DIFFERENT MONTENEGRO REGIONS.

The objective of our research was to compare the results of human papillomavirus (HPV) typing and occurrence of the most important risk factors for cervical cancer obtained in the towns of northern, central and southern regions of Montenegro, in subjects between 30 and 35 years of age, in accordance with the new screening program introduced by the Ministry of Health of Montenegro in 2018. The study included 400 patients aged 30-35 years from Rozaje, Berane, Budva and Podgorica, 100 from each town, who underwent HPV typing in accordance with the latest screening program for early detection and prevention of cervical cancer, approved by the Ministry of Health of Montenegro in 2018. The material was obtained and sampled at the Health Clinics in Rozaje, Berane, Podgorica and Budva. Specially designed brushes were used to take swabs from the cervices, which were then sampled in separate collection tubes that contained a liquid transport medium. The samples were then sent for further analysis to the Institute of Public Health of Montenegro where HPV typing was performed using the real-time polymerase chain reaction method. The results were encrypted and obtained electronically. The data obtained from the questionnaires each subject filled out in accordance with this program were analyzed and the subjects willingly agreed to partake in the screening program. Nearly one-quarter of subjects had a positive HPV finding. The group of HPV positive women included significantly more women from Podgorica (χ2-test=26.455, p<0.001), women with very good living conditions (χ2-test=12.264, p<0.001), women who smoked cigarettes (χ2-test=5.074, p=0.024), women who had the first sexual intercourse between the ages of 17 and 20 (χ2-test=5.874, p=0.015), and women who did not have permanent partners (χ2-test=6.061, p=0.014). Among the observed socio-demographic characteristics and sexual behaviors of our subjects that proved to be non-significant variables in their HPV statuses we excluded the length of smoking habit (χ2-test=0.638, p=0.424) and protected sexual intercourse (χ2-test=2.628, p=0.105). By implementing the screening program and HPV typing, we came to a conclusion that the problem of cervical cancer could be solved or at least mitigated by raising awareness of the causes and incidence of cervical cancer, as well as by being well informed on its curability, predictability and protection during intercourse, which would contribute to positive changes.

Influenza surveillance: determining the epidemic threshold for influenza by using the Moving Epidemic Method (MEM), Montenegro, 2010/11 to 2017/18 influenza seasons.

BACKGROUND: In 2009, an improved influenza surveillance system was implemented and weekly reporting to the World Health Organization on influenza-like illness (ILI) began. The goals of the surveillance system are to monitor and analyse the intensity of influenza activity, to provide timely information about circulating strains and to help in establishing preventive and control measures. In addition, the system is useful for comparative analysis of influenza data from Montenegro with other countries. AIM: We aimed to evaluate the performance and usefulness of the Moving Epidemic Method (MEM), for use in the influenza surveillance system in Montenegro. METHODS: Historical ILI data from 2010/11 to 2017/18 influenza seasons were modelled with MEM. Epidemic threshold for Montenegro 2017/18 season was calculated using incidence rates from 2010/11-2016/17 influenza seasons. RESULTS: Pre-epidemic ILI threshold per 100,000 population was 19.23, while the post-epidemic threshold was 17.55. Using MEM, we identified an epidemic of 10 weeks' duration. The sensitivity of the MEM epidemic threshold in Montenegro was 89% and the warning signal specificity was 99%. CONCLUSIONS: Our study marks the first attempt to determine the pre/post-epidemic threshold values for the epidemic period in Montenegro. The findings will allow a more detailed examination of the influenza-related epidemiological situation, timely detection of epidemic and contribute to the development of more efficient measures for disease prevention and control aimed at reducing the influenza-associated morbidity and mortality.

Lung cancer mortality in Montenegro, 1990 to 2015.

AIM: To analyze the trend of lung cancer mortality in Montenegro from 1990 to 2015. METHODS: Data on lung cancer mortality were collected from death certificates obtained from the Statistical Office of Montenegro for the period 1990-2009 and the Institute for Public Health for the period 2010-2015. Population data were obtained from the Statistical Office of Montenegro. Rates were age-standardized to the World Standard Population, and mortality trends were analyzed with the joinpoint regression. RESULTS: In 2015, lung cancer accounted for 5.44% of all deaths and 22.92% of all cancer deaths. It was the leading cause of all cancer deaths and the third-leading cause of all deaths. A joinpoint was observed in 2004 in women and in the entire population, and in 2005 in men. The overall mortality rates increased from 1990 to 2004 by an average of 3.91% per year and decreased from 2004 to 2015 by an average of 1.95%; which in the entire observed period resulted in an average increase of 1.3% per year. A particularly strong growth rate was observed in women, even 7.14% in the period from 1990 to 2004. CONCLUSION: The observed increase in lung cancer mortality warrants improved tobacco control.

Potential health impact of strong tobacco control policies in 11 South Eastern WHO European Region countries.

Background: While some WHO European Region countries are global tobacco control leaders, the South Eastern region of Europe has the highest tobacco smoking prevalence globally and a relatively low level of overall implementation of the WHO Framework Convention on Tobacco Control (WHO FCTC). An abridged version of SimSmoke has been developed to project the health impact of implementing tobacco control policies in line with the WHO FCTC. Methods: Data on population size, smoking prevalence, policy-specific effect sizes and formulas were applied in 11 South Eastern WHO European Region countries [Albania, Bosnia and Herzegovina (the Federation of Bosnia and Herzegovina and the Republika Srpska), Bulgaria, Croatia, Israel, Montenegro, Republic of Moldova, Romania, Serbia, Slovenia and the former Yugoslav Republic of Macedonia] to project the relative reduction in smoking prevalence, number of smokers and number of smoking-attributable deaths resulting from implementing individual and/or combined six WHO FCTC measures. Results: For all countries, an increase in excise cigarette taxes to 75% of price yields the largest relative reduction in smoking prevalence (range 8-28%). The projections show that within 15 years smoking prevalence can be reduced by at least 30% in all countries when all six tobacco control measures are fully implemented in line with the WHO FCTC. Conclusion: The projections show that large health effects can be achieved and the results can be used as an advocacy tool towards acceleration of the enforcement of tobacco control laws in WHO European Region countries.

Adverse drug reaction reporting and development of pharmacovigilance systems in Bosnia and Herzegovina, Croatia, Serbia, and Montenegro: a retrospective pharmacoepidemiological study.

AIM: To compare individual case safety reports (ICSR) rates and characteristics between Croatia, Serbia, Montenegro, and Bosnia and Herzegovina (B&H). METHODS: This retrospective pharmacoepidemiological study used the data from ICSR received by the Agency for Medicines and Medical Devices in B&H in 2011-2016. The number, characteristics, and sources of reports, suspected drugs, and patient characteristics were analyzed. The results were compared with the publicly available data from Croatia, Serbia, and Montenegro. RESULTS: The number of reported adverse drug reactions per one million of inhabitants was lowest in B&H and highest in Croatia. There were significant differences in reporter characteristics, sources of reports, and the percentage of missing data in ICSR, while the Anatomical Therapeutic Chemical product classes, patient's sex, and adverse drug reaction System Organ Classes were similar. CONCLUSION: Despite the historical and geographical vicinity of B&H and its neighboring countries, there were significant differences in indicators of pharmacovigilance development.

Hepatitis C virus genotype 3A in a population of injecting drug users in Montenegro: Bayesian and evolutionary analysis.

Few reports are available on HCV molecular epidemiology among IDUs in Eastern Europe, and none in Montenegro. The aim of this study was to investigate the HCV genotype distribution in Montenegro among IDUs and to perform Bayesian and evolutionary analysis of the most prevalent HCV genotype circulating in this population. Sixty-four HCV-positive IDUs in Montenegro were enrolled between 2013 and 2014, and the NS5B gene was sequenced. The Bayesian analysis showed that the most prevalent subtype was HCV-3a. Phylogenetic data showed that HCV-3a reached Montenegro in the late 1990s, causing an epidemic that exponentially grew between the 1995 and 2005. In the dated tree, four different entries, from 1990 (clade D), 1994 (clade A) to 1999 (clade B) and 2001 (clade C), were identified. In the NS5B protein model, the amino acids variations were located mainly in the palm domain, which contains most of the conserved structural elements of the active site. This study provides an analysis of the virus transmission pathway and the evolution of HCV genotype 3a among IDUs in Montenegro. These data could represent the basis for further strategies aimed to improve disease management and surveillance program development in high-risk populations.

Health-related quality of life in adolescents with epilepsy in Montenegro.

OBJECTIVE: The objective of this study was to establish potential risk factors for poor health-related quality of life among adolescents with epilepsy in Montenegro. MATERIAL AND METHODS: A sample of 104 adolescents with epilepsy (age: 11-19years) at a tertiary referral center in Podgorica, Montenegro, completed the validated Serbian version of the QOLIE-AD-48 questionnaire. They were divided into two groups: a group with active epilepsy (60 adolescents) and a group with inactive epilepsy (44 adolescents). Demographic and clinical data were collected. RESULTS: Adolescents with active epilepsy had low quality of life and felt the negative impact of the disease. They also had more cognitive impairments, felt more stigmatized, and had considerably more distorted perception of their health than adolescents with inactive epilepsy (p<0.05). Females reported better social support than males (p<0.05). Older males had lower grades at school (p<0.05) than the younger ones. As expected, adolescents with the highest number of seizures in the past two years had the lowest quality of life (p<0.05). CONCLUSION: In our study, the quality of life in adolescents with epilepsy was determined by severity of the disease, age, and gender.

Haemorrhagic fever with renal syndrome in Montenegro, 2004-14.

From 2004 to 2014, 106 cases of Human haemorrhagic fever with renal syndrome were notified in Montenegro, with a peak in 2014. Most of the cases occurred in summer, in the North-east and Central Montenegro, a hilly/mountainous area, that provides suitable habitats for the main rodent carriers. Cases were mainly males (71) and exposures were often working outdoor or spending time visiting mountains and lakes. Incidence correlated with average annual temperature increase and average annual rainfalls decrease, but not with land cover. Environment and climate effects on HFRS in Montenegro need further investigation to get insight into future trends.

Hypertension and correlates among Montenegrin schoolchildren-a cross-sectional study.

OBJECTIVES: In one of the few national studies of children in a former Eastern bloc country emerging as a Western democracy and the first such study ever in Montenegro, this study establishes the prevalence and correlates of childhood hypertension (CH). STUDY DESIGN: A cross-sectional national study. METHODS: The study was conducted with 3254 children aged 7-13 years (50.3% male) from 39 elementary schools. We used a structured questionnaire to gather sociodemographic information as well as data on factors potentially related to CH. Children's nutritional status was assessed using the criteria of the International Obesity Task Force. Waist circumference was also measured. Blood pressure was measured in schools using an oscillometric monitor. CH was defined as an average systolic blood pressure and/or diastolic blood pressure greater than or equal to the 95th percentile for sex, age, and height. RESULTS: The prevalence of CH was 10.4% with no differences between boys and girls. Multiple regression revealed that the odds for child hypertension were lowered by 10% for each year of age. On the other hand, rural environment and child obesity raised the odds of hypertension by 38% and 68%, respectively. CONCLUSIONS: We found hypertension in one out of ten Montenegrin schoolchildren, with no gender differences. Obesity and rural areas may be unfriendly to children's blood pressure.

The association between pro-arrhythmic agents and aortic stenosis in young adults: is it sufficient to clarify the sudden unexpected deaths?

Most young patients with mild-to-moderate aortic stenosis show no symptoms, and sudden death appears only occasionally. We hypothesised that malignant ventricular arrhythmias could be responsible for the high incidence of sudden death in such patients. If multiple factors such as asymptomatic aortic stenosis in association with arrhythmia-provoking agents are involved, could it be sufficient to account for sudden unexpected death? In this study, eight cases of sudden death in young adults, with ages ranging from 22 to 36 years, who had never reported any symptoms that could be related to aortic stenosis, were investigated. Full autopsies were performed, and congenital aortic stenosis in all eight cases was confirmed. DNA testing for channelopathies was negative. Comprehensive toxicological analyses found an electrolyte imbalance, or non-toxic concentrations of amitriptyline, terfenadine, caffeine, and ethanol. Collectively, these results suggest that congenital asymptomatic aortic stenosis without cardiac hypertrophy in young adults is not sufficient to cause sudden death merely on its own; rather, an additional provoking factor is necessary. According to our findings, the provoking factor may be a state of physical or emotional stress, a state of electrolyte imbalance, or even taking a therapeutic dose of a particular drug.
