Socioeconomic position is associated with N-terminal pro-brain natriuretic peptide (NT-proBNP)-Results of the population-based Heinz Nixdorf Recall study.

OBJECTIVES: N-Terminal pro Brain Natriuretic Peptide (NT-proBNP) is a diagnostic marker for heart failure and a prognostic factor for cardiovascular disease (CVD). The aim of this study was to examine the association of socioeconomic position (SEP) with NT-proBNP while assessing sex-differences and the impact of CVD risk factors and prevalent CVD on the association. METHODS: Baseline data of 4598 participants aged 45-75 years of the Heinz Nixdorf Recall Study were used. Income and education were used as SEP indicators. Age- and sex-adjusted linear regression models were fitted to calculate effect size estimates and 95% confidence intervals (95%-CIs) for the total effect of SEP indicators on NT-proBNP, while potential mediation was assessed by additionally accounting for traditional CVD risk factors (i.e., systolic blood pressure, HDL cholesterol, LDL cholesterol, diabetes, anti-hypertensive medication, lipid-lowering medication, BMI, current smoking). Education and income were included separately in the models. RESULTS: With an age- and sex-adjusted average change in NT-proBNP of -6.47% (95%-CI: -9.91; -2.91) per 1000€, the association between income and NT-proBNP was more pronounced compared to using education as a SEP indicator (-0.80% [95%-CI: -1.92; 0.32] per year of education). Sex-stratified results indicated stronger associations in men (-8.43% [95%-CI: -13.21; -3.38] per 1000€; -1.63% [95%-CI: -3.23; -0.001] per year of education) compared to women (-5.10% [95%-CI: -9.82; -0.01] per 1000€; -1.04% [95%-CI: -2.59; 0.50] per year of education). After adjusting for CVD risk factors some of the observed effect size estimates were attenuated, while the overall association between SEP indicators and NT-proBNP was still indicated. The exclusion of participants with prevalent coronary heart disease or stroke did not lead to a substantial change in the observed associations. CONCLUSIONS: In the present study associations of education and income with NT-proBNP were observed in a population-based study sample. Only parts of the association were explained by traditional CVD risk factors, while there were substantial sex-differences in the strength of the observed association. Overt coronary heart disease or stroke did not seem to trigger the associations.

Assessment of Coagulation and Hemostasis Biomarkers in a Subset of Patients With Chronic Cardiovascular Disease.

Measurement of a single marker of coagulation may not provide a complete picture of hemostasis activation and fibrinolysis in patients with chronic cardiovascular diseases. We assessed retrospective orders of a panel which included prothrombin fragment 1.2 (PF1.2), thrombin: antithrombin complexes, fibrin monomers, and D-dimers in patients with heart assist devices, cardiomyopathies, atrial fibrillation and intracardiac thrombosis (based on ordering ICD-10 codes). During 1 year there were 117 panels from 81 patients. Fifty-six (69%) patients had heart assist devices, cardiomyopathy was present in 17 patients (21%) and 29 patients (36%) had more than 1 condition. PF1.2 was most frequently elevated in patients with cardiomyopathy (61.1%) compared to those with cardiac assist devices (15.7%; P = 0.0002). D-dimer elevation was more frequent in patients with cardiac assist devices (98.8%) compared to those patients with cardiomyopathy (83.3%; P = 0.014). Patients with cardiomyopathy show increases of PF1.2 suggesting thrombin generation. In contrast, elevations of D-dimers without increase in other coagulation markers in patients with cardiac assist devices likely reflect the presence of the intravascular device and not necessarily evidence of hemostatic activation.

Impact of Radiation on Cardiovascular Outcomes in Older Resectable Esophageal Cancer Patients With Medicare.

OBJECTIVES: Preoperative radiotherapy improves outcomes for operable esophageal cancer patients, though the proximity of the heart to the esophagus puts patients at risk of radiation-induced cardiovascular disease. This study characterizes the impact of radiotherapy and different radiation techniques on cardiovascular morbidity among a cohort of esophageal cancer patients. MATERIALS AND METHODS: We identified 1125 patients aged 65 and older diagnosed between 2000 and 2011 with esophageal cancer who received surgery alone, or surgery preceded by either preoperative chemotherapy or preoperative chemoradiation from the Surveillance Epidemiology and End Results (SEER)-Medicare database. We used Medicare claims to identify severe perioperative and late cardiovascular events. Multivariable logistic regression and Fine-Gray models were used to determine the effect of presurgery treatment on the risk of perioperative and late cardiovascular disease. RESULTS: Preoperative chemotherapy or chemoradiation did not significantly increase the risk of perioperative cardiovascular complications compared with surgery alone. Patients treated with preoperative chemoradiation had a 36% increased risk of having a late cardiovascular event compared with patients treated with surgery alone (subdistribution hazard ratio [SDHR]: 1.36; P=0.035). There was no significant increase in late cardiovascular events among patients treated with preoperative chemotherapy (SDHR: 1.18; P=0.40). Among patients treated with preoperative chemoradiation, those receiving intensity modulated radiotherapy had a 68% decreased risk of having a late cardiovascular event compared with patients receiving conventional radiation (SDHR: 0.32; P=0.007). CONCLUSIONS: This study demonstrates an increased risk of cardiovascular complications among operative esophageal cancer patients treated with preoperative chemoradiation, though these risks might be reduced with more cardioprotective radiation techniques such as intensity modulated radiotherapy.

Dynamics of detailed components of metabolic syndrome associated with the risk of cardiovascular disease and death.

Few studies quantify a cascade of dynamic transitions on the detailed components of metabolic syndrome (MetS) and subsequent progressions to cardiovascular disease (CVD) and its death. A total of 47,495 subjects repeatedly attending a community-based integrated screening program in Taiwan were recruited. The refined MetS-related classification (RMRC) in relation to five criteria of MetS was defined as free of metabolic disorder (FMD, none of any criteria), mild metabolic disorder (MMD, 1-2 criteria) and MetS. A multistate Markov model was used for modelling such a multistate process. The estimated progression rate from FMD to MMD was 44.82% (95% CI 42.95-46.70%) whereas the regression rate was estimated as 29.11% (95% CI 27.77-30.45%). The progression rate from MMD to MetS was estimated as 6.15% (95% CI 5.89-6.42%). The estimated annual incidence rates of CVD increased with the severity of RMRC, being 1.62% (95% CI 1.46-1.79%) for FMD, 4.74% (95% CI 4.52-4.96%) for MMD, to 20.22% (95% CI 19.52-20.92%) for MetS. The estimated hazard rate of CVD death was 6.1 (95% CI 4.6-7.7) per thousand. Elucidating the dynamics of MetS-related transition and quantifying the incidence and prognosis of CVD provide a new insight into the design and the evaluation of intervention programs for CVD.

Comparative risk assessment for the development of cardiovascular diseases in the Hungarian general and Roma population.

Cardiovascular diseases (CVDs) are the number one cause of death globally, and the early identification of high risk is crucial to prevent the disease and to reduce healthcare costs. Short life expectancy and increased mortality among the Roma are generally accepted (although not indeed proven by mortality analyses) which can be partially explained by the high prevalence of cardiovascular risk factors (CVRF) among them. This study aims to elaborate on the prevalence of the most important CVD risk factors, assess the estimation of a 10-year risk of development of fatal and nonfatal CVDs based on the most used risk assessment scoring models, and to compare the Hungarian general (HG) and Roma (HR) populations. In 2018 a complex health survey was accomplished on the HG (n = 380) and HR (n = 347) populations. The prevalence of CVRS was defined and 10-year cardiovascular risk was estimated for both study populations using the following systems: Framingham Risk Score for hard coronary heart disease (FRSCHD) and for cardiovascular disease (FRSCVD), Systematic COronary Risk Evaluation (SCORE), ACC/AHA Pooled Cohort Equations (PCE) and Revised Pooled Cohort Equations (RPCE). After the risk scores had been calculated, the populations were divided into risk categories and all subjects were classified. For all CVD risk estimation scores, the average of the estimated risk was higher among Roma compared to the HG independently of the gender. The proportion of high-risk group in the Hungarian Roma males population was on average 1.5-3 times higher than in the general one. Among Roma females, the average risk value was higher than in the HG one. The proportion of high-risk group in the Hungarian Roma females population was on average 2-3 times higher compared to the distribution of females in the general population. Our results show that both genders in the Hungarian Roma population have a significantly higher risk for a 10-year development of cardiovascular diseases and dying from them compared to the HG one. Therefore, cardiovascular interventions should be focusing not only on reducing smoking among Roma but on improving health literacy and service provision regarding prevention, early recognition, and treatment of lipid disorders and diabetes among them.

Racial and Ethnic Differences in Presentation and Outcomes for Patients Hospitalized With COVID-19: Findings From the American Heart Association's COVID-19 Cardiovascular Disease Registry.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has exposed longstanding racial and ethnic inequities in health risks and outcomes in the United States. We aimed to identify racial and ethnic differences in presentation and outcomes for patients hospitalized with COVID-19. METHODS: The American Heart Association COVID-19 Cardiovascular Disease Registry is a retrospective observational registry capturing consecutive patients hospitalized with COVID-19. We present data on the first 7868 patients by race/ethnicity treated at 88 hospitals across the United States between January 17, 2020, and July 22, 2020. The primary outcome was in-hospital mortality. Secondary outcomes included major adverse cardiovascular events (death, myocardial infarction, stroke, heart failure) and COVID-19 cardiorespiratory ordinal severity score (worst to best: death, cardiac arrest, mechanical ventilation with mechanical circulatory support, mechanical ventilation with vasopressors/inotrope support, mechanical ventilation without hemodynamic support, and hospitalization alone. Multivariable logistic regression analyses were performed to assess the relationship between race/ethnicity and each outcome adjusting for differences in sociodemographic, clinical, and presentation features, and accounting for clustering by hospital. RESULTS: Among 7868 patients hospitalized with COVID-19, 33.0% were Hispanic, 25.5% were non-Hispanic Black, 6.3% were Asian, and 35.2% were non-Hispanic White. Hispanic and Black patients were younger than non-Hispanic White and Asian patients and were more likely to be uninsured. Black patients had the highest prevalence of obesity, hypertension, and diabetes. Black patients also had the highest rates of mechanical ventilation (23.2%) and renal replacement therapy (6.6%) but the lowest rates of remdesivir use (6.1%). Overall mortality was 18.4% with 53% of all deaths occurring in Black and Hispanic patients. The adjusted odds ratios for mortality were 0.93 (95% CI, 0.76-1.14) for Black patients, 0.90 (95% CI, 0.73-1.11) for Hispanic patients, and 1.31 (95% CI, 0.96-1.80) for Asian patients compared with non-Hispanic White patients. The median odds ratio across hospitals was 1.99 (95% CI, 1.74-2.48). Results were similar for major adverse cardiovascular events. Asian patients had the highest COVID-19 cardiorespiratory severity at presentation (adjusted odds ratio, 1.48 [95% CI, 1.16-1.90]). CONCLUSIONS: Although in-hospital mortality and major adverse cardiovascular events did not differ by race/ethnicity after adjustment, Black and Hispanic patients bore a greater burden of mortality and morbidity because of their disproportionate representation among COVID-19 hospitalizations.

THE ASSESSMENT OF COMORBID PATHOLOGY IN CLEAN-UP WORKERS OF THE ACCIDENT CONSEQUENCES AT THE CHORNOBYL NPP HAVING CARDIOVASCULAR DISEASES. / OTsINKA KOMORBIDNOÏ PATOLOGIÏ V UChASNYKIV LIKVIDATsIÏ NASLIDKIV AVARIÏ NA ChORNOBYL'S'KII AES Z ZAKhVORIuVANNIaMY SERTsEVO-SUDYNNOÏ SYSTEMY.

OBJECTIVE: Analysis of comorbid pathology based on the use of methods for its quantitative assessment in personswho were exposed to radiation because of the Chornobyl accident. MATERIALS AND METHODS: Comorbid pathology was studied in 608 men, including 420 clean-up workers (CW) of theaccident consequences at the Chornobyl NPP (main group) and 188 non-irradiated persons (control group - CG). Allpatients had cardiovascular diseases as their main pathology and were examined in the cardiology department ofthe NRCRM hospital during 2011-2019. The groups did not differ by age, either at the beginning of the accident orat the time of their last examination. Patients of both groups before the accident were practically healthy peopleand were not registered at the dispensary. The Cumulative Illness Rating Scale (CIRS) was used to quantify comorbid pathology. RESULTS: Comorbid pathology was detected in 418 CW (99.5 %) and 183 patients of CG (99.3 %). The total score inCW (10.3 ± 2.9) units significantly (р = 0.000) exceeded the same index in non-irradiated patients (8.8 ± 3.0) units,as well as the mean number of CIRS categories, whose level severity was 1 point (3.3 ± 1.7 vs. 2.6 ± 1.5, р = 0.000),2 points (1.8 ± 1.0 vs. 1.6 ± 1.0, p = 0.032) and 3-4 points (1.2 ± 0.8 vs. 1.0 ± 0.9, р = 0.062). In contrast, the meanvalue of the categories with zero score, i.e. without diseases, was more common in CG (7.8 ± 1.8 vs. 8.8 ± 1.7,р = 0.000). The most common pathology in CW and CG were heart (98.3 % vs. 94.7 %, р < 0.05) and vascular diseases(92.9 % vs. 87.8 %, р > 0.05), followed by diseases of nervous system (79.0 % vs. 57.4 %, р <0.001), musculoskeletal system and skin (69.8 % vs. 56.9 %, р < 0.01), endocrine (56.0 % vs. 49,5 %, р > 0.05) and the respiratory system (53.8 % vs. 53.7 %, р > 0.05) and liver (51.2 % vs. 36.2 %, р < 0.001), which were detected more than in halfpatients of the main group. Diseases of the kidneys (3.3 % vs. 4.8 %, р > 0.05) and lower gastrointestinal tract(3.3 % vs. 0.5 %, р < 0.01) were quite rare. The incidence of the other four CIRS categories was 18.6-34 %. The totalscore in subgroups with different ages varied in descending order of mean values as follows: CW > 65 years (10.5 ± 2.9)units, CW < 65 years (9.9 ± 2.8) units, CG > 65 years (9.5 ± 2.8) units and CG < 65 years (7.8 ± 2.9) units with significant differences both between age subgroups in each of the groups and between CW and CG older subgroups. CONCLUSIONS: Quantitative assessment of comorbidity by CIRS showed that in persons irradiated during their emergency work due to the Chornobyl accident, the incidence of combined pathology of such organ systems as cardiovascular, nervous, endocrine, hematopoietic, urogenital, musculoskeletal, gastrointestinal, liver and kidneys wassignificantly higher than in non-irradiated patients. In irradiated patients, the course of comorbid pathology wasmore severe for each system and in general, reflecting higher values of the total CIRS score. Both among CW andnon-irradiated controls, higher values of the total comorbidity score were observed in patients 65 years and older,compared with younger individuals. In both age subgroups of CW the total score was higher than in patients of thecontrol group.

Age- and cause-specific contributions to the life expectancy gap between Medical Aid recipients and National Health Insurance beneficiaries in Korea, 2008-2017.

Recipients of Medical Aid, a government-funded social assistance program for the poor, have a shorter life expectancy than National Health Insurance beneficiaries in Korea. This study aims to explore the contributions of age and major causes of death to the life expectancy difference between the two groups. We used the National Health Information Database provided by the National Health Insurance Service individually linked to mortality registration data of Statistics Korea between 2008 and 2017. Annual abridged life tables were constructed and Arriaga's life expectancy decomposition method was employed to estimate age- and cause-specific contributions to the life expectancy gap between National Health Insurance beneficiaries and Medical Aid recipients. The life expectancy difference between National Health Insurance beneficiaries and Medical Aid recipients was 14.5 years during the period of 2008-2017. The age groups between 30 and 64 years accounted for 78.7% and 67.5% of the total life expectancy gap in men and women, respectively. Cancer was the leading cause of death contributing to excess mortality among Medical Aid recipients compared to National Health Insurance beneficiaries. More specifically, alcohol-attributable deaths (such as alcoholic liver disease, liver cancer, liver cirrhosis, and alcohol/substance abuse), suicide, and cardiometabolic risk factor-related deaths (such as cerebrovascular disease, ischemic heart disease, and diabetes) were the leading contributors to the life expectancy gap. To decrease excess deaths in Medical Aid recipients and reduce health inequalities, effective policies for tobacco and alcohol regulation, suicide prevention, and interventions to address cardiometabolic risk factors are needed.

Telomeres and telomerase in risk assessment of cardiovascular diseases.

Telomeres are repetitive nucleoprotein structures located at the ends of chromosomes. Reduction in the number of repetitions causes cell senescence. Cells with high proliferative potential age with each replication cycle. Post-mitotic cells (e.g. cardiovascular cells) have a different aging mechanism. During the aging of cardiovascular system cells, permanent DNA damage occurs in the telomeric regions caused by mitochondrial dysfunction, which is a phenomenon independent of cell proliferation and telomere length. Mitochondrial dysfunction is accompanied by increased production of reactive oxygen species and development of inflammation. This phenomenon in the cells of blood vessels can lead to atherosclerosis development. Telomere damage in cardiomyocytes leads to the activation of the DNA damage response system, histone H2A.X phosphorylation, p53 activation and p21 and p16 protein synthesis, resulting in the SASP phenotype (senescence-associated secretory phenotype), increased inflammation and cardiac dysfunction. Cardiovascular cells show the activity of the TERT subunit of telomerase, an enzyme that prevents telomere shortening. It turns out that disrupting the activity of this enzyme can also contribute to the formation of cardiovascular diseases. Measurements of telomere length according to the "blood-muscle" model may help in the future to assess the risk of cardiovascular complications in people undergoing cardiological procedures, as well as to assess the effectiveness of some drugs.

Association of Zinc and Copper Status with Cardiovascular Diseases and their Assessment Methods: A Review Study.

Cardiovascular disease (CVD) is the leading cause of mortality, morbidity, and financial losses and has a high prevalence across the world. Several studies have investigated the association between various CVD types with zinc and copper status as the essential minerals for the human body, proposing contradictory and similar results. This narrative review aimed to survey the correlations between zinc and copper status in the human body and some risk factors of CVD, as well as the assessment methods of zinc and copper status in the human body. According to the reviewed articles, zinc and copper deficiency may increase the risk of coronary heart disease, valvular regurgitation, and myocardial lesions, cardiac hypertrophy. Furthermore, it could lead to the expanded mitochondrial compartments of the heart, acute and chronic heart failure, and elevation of inflammation markers, such as interleukin-1 (IL-1) and IL-6. Two methods are primarily used for the assessment of zinc and copper in the human body, including the direct method (measurement of their concentrations) and indirect method (determining the activity of zinc- and copper-containing enzymes). Both these methods are considered reliable for the assessment of the zinc and copper levels in healthy individuals. Serum or plasma levels of these elements are also commonly used for the assessment of the correlation between zinc and copper status and CVD. But, which one is a more accurate indicator in relation to CVD is not yet clear; therefore, further studies are required in this field.

Measuring satisfaction with health care services for Vietnamese patients with cardiovascular diseases.

Patient satisfaction is a useful predictor of adherence and outcomes of cardiovascular diseases (CVDs) treatment. This study explored the satisfaction of Vietnamese CVDs inpatients and outpatients using a scale specifically designed for CVDs patients and examined the factors associated with satisfaction towards CVDs treatment services. Interviews of 600 patients at the Hanoi Heart Hospital were conducted. We developed a measurement scale for both inpatient and outpatient services. Multivariate Tobit regression was used to determine the associated factors with patient satisfaction. For inpatients, Cronbach's alpha reported for the domains were in the range of 0.72-0.97, while for outpatients, Cronbach's alpha was within 0.61-0.97. Overall, patients were more satisfied with inpatient services (Mean = 81.8, SD = 5.8) than outpatient services (Mean = 79.7, SD = 5.2, p<0.05). In inpatients, the highest complete satisfaction was in "Attitude of Nurse" item (42.0%), the highest satisfaction score was in "Care and treatment" domain (Mean = 85.6, SD = 9.7) and the lowest in "Hospital facilities" domain (Mean = 78.3; SD = 9.2). Among outpatients, the highest complete satisfaction was in "Attitude of physicians when examining, guiding and explaining to the patient" item (19.7%), the highest satisfaction score was in "Attitude of medical staff" domain (Mean = 82.8; SD = 7.9) and the lowest in "Waiting time" domain (Mean = 76.6; SD = 8.2). People not having health insurances had significantly higher scores in "Waiting time", "Hospital facilities" and "Attitude of staff" domains (for outpatients) and in "Health service accessibility", "Hospital facilities" domains (for inpatients) as well as higher total satisfaction score than those having health insurance. Findings discovered through the application of the newly developed instrument showed low satisfaction regarding hospital facilities for inpatients and waiting time for outpatients, suggesting renovation efforts, while inferiority regarding patient satisfaction of health insurance covered patients compared to those without implied policy reform possibility. Further enhancement and validation of the developed instrument was required.

Noncommunicable disease burden among conflict-affected adults in Ukraine: A cross-sectional study of prevalence, risk factors, and effect of conflict on severity of disease and access to care.

BACKGROUND: There is limited research on noncommunicable diseases (NCDs) in humanitarian settings despite the overall global burden and disproportionate growth in many conflicts and disaster-prone settings. This study aimed to determine the prevalence of NCDs and assess the perceived effect of conflict on NCD severity and access to treatment among conflict-affected adults (≥ 30 years) in Ukraine. METHODS AND FINDINGS: We conducted two population-representative, stratified, cross-sectional household surveys: one among adult internally displaced people (IDPs) throughout Ukraine and one among adults living in Donbas in eastern Ukraine. One randomly selected adult per household answered questions about their demographics, height and weight, diagnosed NCDs, access to medications and healthcare since the conflict began, as well as questions assessing psychological distress, trauma exposure, and posttraumatic stress disorder. More than half of participants reported having at least one NCD (55.7% Donbas; 59.8% IDPs) A higher proportion of IDPs compared to adults in Donbas experienced serious psychological distress (29.9% vs. 18.7%), interruptions in care (9.7-14.3% vs. 23.1-51.3%), and interruptions in medication than adults in Donbas (14.9-45.6% vs. 30.2-77.5%). Factors associated with perceived worsening of disease included psychological distress (p: 0.002-0.043), displacement status (IDP vs. Donbas) (p: <0.001-0.011), interruptions in medication (p: 0.002-0.004), and inability to see a doctor at some point since the start of the conflict (p: <0.001-0.008). CONCLUSIONS: Our study found a high burden of NCDs among two conflict-affected populations in Ukraine and identified obstacles to accessing care and medication. Psychological distress, interruptions to care, and interruptions in medication were all reported by a higher proportion of IDPs than adults in Donbas. There is a need for targeted policies and programs to support the unique needs of displaced conflict-affected individuals in Ukraine that address the economic and perceived barriers to NCD treatment and care.

Frailty and Comprehensive Geriatric Assessment.

Frailty is defined as a reduced physiologic reserve vulnerable to external stressors. For older individuals, frailty plays a decisive role in increasing adverse health outcomes in most clinical situations. Many tools or criteria have been introduced to define frailty in recent years, and the definition of frailty has gradually converged into several consensuses. Frail older adults often have multi-domain risk factors in terms of physical, psychological, and social health. Comprehensive geriatric assessment (CGA) is the process of identifying and quantifying frailty by examining various risky domains and body functions, which is the basis for geriatric medicine and research. CGA provides physicians with information on the reversible area of frailty and the leading cause of deterioration in frail older adults. Therefore frailty assessment based on understanding CGA and its relationship with frailty, can help establish treatment strategies and intervention in frail older adults. This review article summarizes the recent consensus and evidence of frailty and CGA.

RETROSPECTIVE ASSESSMENT OF CLINICAL-MORPHOLOGICAL CHANGES OF THE HEPATOBILIARY SYSTEM IN LIVER CIRRHOSIS OF THE CHORNOBYL NPP ACCIDENT CLEAN-UP WORKERS. / RETROSPEKTYVNA OTsINKA KLINIKO-MORFOLOGIChNYKh ZMIN GEPATOBILIARNOÏ SYSTEMY PRY TsYROZI PEChINKY V UChASNYKIV LIKVIDATsIÏ NASLIDKIV ChORNOBYL'S'KOÏ KATASTROFY.

OBJECTIVE: to retrospectively characterize changes in the hepatobiliary system in liver cirrhosis (LC) in the clean-up workers of the Chornobyl NPP accident and to determine the factors of disease progression according to the expert materials of the Central Interagency Expert Commission on Establishing the Causal Relationship of the Diseases with the influence of factors of Chornobyl NPP accident. MATERIALS AND METHODS: Based on the data of 60 cases of the Central Interagency Expert Committee on establishing the causal link of diseases with the impact of the Chornobyl NPP accident, the factors of development, concomitant pathology and indicators of the hepatobiliary system status in 49 deceased and 11 alive clean-up workers with LC were investigated. RESULTS: A retrospective study of the morphological changes of the hepatobiliary system in the clean-up workers with LC showed that the main pathologic anatomical diagnosis in 37.8 % of cases was small-nodal LC, in 8.9 % - micromacronodular, in 4.4 % - large-nodal, in 2.2 % - primary biliary LC, in the other 40 % of cases - LC with uncer- tain nodal structure, as well as 2 (4.4 %) cases of fatty liver and 1 case (2.2 %) of portal cirrhosis against the back- ground of fatty liver. Pathomorphological changes were characterized by expressed growth of fibrous tissue with replacement of the liver parenchyma (fields of fibrosis), increase in size and impaired structure of the liver, thick- ening and tightening of its capsule, fibrotic changes in other organs - gastric mucosa, pancreas, spleen, lungs, heart. Histological examination revealed lobe structure abnormalities, false lobules, periportal fibrosis, lymphoid-lympho- cytic infiltration, diffuse fatty small-sized and large-drop dystrophy, and hepatocyte atrophy. Common inflammato- ry processes and fibrotic changes of other organs and systems: cardiovascular, urinary, bronchopulmonary, stomach, pancreas and spleen made the course of the LC more severe. The most frequent were cardiovascular diseases, signi- ficantly more frequent among the deceased than alive patients: hypertension - 67.3 % and 45.5 %, p < 0.05, coro- nary heart disease - 57.1 % and 18 %, p < 0.05. In most cases, the cause of death in the clean-up workers with LC was hepatic and cellular failure (53.3 %), which together with hepatic-renal failure (17.8 %) made 71.1 %. CONCLUSION: Changes in the hepatobiliary system of change in in the clean-up workers with LC were characterized by marked growth of fibrotic tissue with replacement of the parenchyma and impaired liver structure, fibrotic changes in other organs, diffuse fatty small and large droplet dystrophy and atrophy of hepatocytes. The severe course of the LC with the manifestation of the disease at the stage of decompensation was due to a vague clinical picture, lack of subjective symptoms of liver disease, slow, steadily progressing development, lack of or inadequate examination and treatment, a significant number of concomitant pathology of other organs and systems. The fac- tors of the development of LC in the clean-up workers were the long course of chronic liver disease, numerous con- comitant pathology, long stay in the accident zone, the effect of ionizing radiation, as well as the lack of dispensa- ry supervision and adequate treatment.

A longitudinal study on perceived health in cardiovascular patients: The role of conscientiousness, subjective wellbeing and cardiac self-efficacy.

Cardiovascular disease (CVD) is the world's most prevalent chronic disease and the leading chronic cause of morbidity. There are several psychosocial factors associated with quality of life during CVD. Our main objectives were to analyze the roles of conscientiousness, subjective wellbeing and self-efficacy beliefs. The sample comprised 514 patients (mean age 63.57 years) who were assessed twice over a nine-month interval. At Time 1, participants answered a questionnaire assessing conscientiousness, perceived subjective wellbeing (positive and negative affect, life satisfaction), cardiac self-efficacy and health-related quality of life (HRQoL). The same variables (except for conscientiousness) were re-assessed at Time 2. Results showed that conscientiousness had a positive relation with subjective wellbeing, cardiac self-efficacy, and HRQoL at Time 1. Moreover, cardiac self-efficacy at Time 1 had a positive longitudinal effect on HRQoL at Time 2, while controlling for autoregressive effects. Mediation analyses indicated that the relationship between conscientiousness and HRQoL was mediated by positive affect and cardiac self-efficacy. These results suggest the usefulness of psychosocial interventions aimed at promoting positive affect and self-efficacy beliefs among CVD patients.
