Mapping Hungarian procedure codes to SNOMED CT.

BACKGROUND: Data harmonisation is essential in real-world data (RWD) research projects based on hospital information systems databases, as coding systems differ between countries. The Hungarian hospital information systems and the national claims database use internationally known diagnosis codes, but data on medical procedures are recorded using national codes. There is no simple or standard solution for mapping the national codes to a standard coding system. Our aim was to map the Hungarian procedure codes (OENO) to SNOMED CT as part of the European Health Data Evidence Network (EHDEN) project. METHODS: We recruited 25 professionals from different specialties to manually map the procedure codes used between 2011 and 2021. A mapping protocol and training material were developed, results were regularly revised, and the challenges of mapping were recorded. Approximately 7% of the codes were mapped by more people in different specialties for validation purposes. RESULTS: We mapped 4661 OENO codes to standard vocabularies, mostly SNOMED CT. We categorized the challenges into three main areas: semantic, matching, and methodological. Semantic refers to the occasionally unclear meaning of the OENO codes, matching to the different granularity and purpose of the OENO and SNOMED CT vocabularies. Lastly, methodological challenges were used to describe issues related to the design of the above-mentioned two vocabularies. CONCLUSIONS: The challenges and solutions presented here may help other researchers to design their process to map their national codes to standard vocabularies in order to achieve greater consistency in mapping results. Moreover, we believe that our work will allow for better use of RWD collected in Hungary in international research collaborations.

Neutrophil-to-Lymphocyte Ratio Is an Independent Risk Factor for Coronary Artery Disease in Central Obesity.

Several inflammatory biomarkers were found to be associated with an increased risk of cardiovascular disease. Neutrophil-to-lymphocyte ratio (NLR) is a marker of subclinical inflammation that increases with the stress response. Visceral adiposity index (VAI) calculated as a combination of anthropometric and metabolic parameters reflects both the extent and function of visceral adipose tissue. Given the association of subclinical inflammation with both obesity and cardiovascular diseases, it is plausible that the inflammation-CVD association is modulated by the amount and function of adipose tissue. Thus, our aim was to examine the association between NLR and coronary artery calcium score (CACS), an intermediate marker of coronary artery disease in asymptomatic patients across VAI tertiles. Methods: Data from 280 asymptomatic participants of a cardiovascular screening program were analysed. In addition to the collection of lifestyle and medical history, a non-contrast cardiac CT scan and laboratory tests were performed on all participants. Multivariate logistic regression was conducted with CACS > 100 as the outcome and with conventional cardiovascular risk factors and NLR, VAI, and NLR by VAI tertile as predictors. Results: We found an interaction between VAI tertiles and NLR; NLR values were similar in the lower VAI tertiles, while they were higher in the CACS > 100 in the 3rd VAI tertile (CACS ≤ 100: 1.94 ± 0.58 vs. CACS > 100: 2.48 ± 1.1, p = 0.008). According to multivariable logistic regression, the interaction between NLR and VAI tertiles remained: NLR was associated with CACS > 100 in the 3rd VAI tertile (OR = 1.67, 95% CI 1.06-2.62, p = 0.03) but not in the lower tertiles even after adjustment for age, sex, smoking, history of hypertension, hyperlipidaemia, and diabetes mellitus, as well as high-sensitivity C-reactive protein. Our findings draw attention to the independent association between subclinical, chronic, systemic inflammation and subclinical coronary disease in obesity.

Level of advanced oxidation protein products is associated with subclinical atherosclerosis.

BACKGROUND: Oxidative stress is an important factor in the pathomechanism of atherosclerosis. Advanced oxidation protein products (AOPPs) are considered markers of oxidative stress. Thickening of the carotid intima-media layers indicates subclinical atherosclerosis and can be detected by carotid ultrasound. OBJECTIVE: Our aim was to examine the association between carotid intima-media thickness (CIMT) and the level of AOPPs. METHODS: Carotid duplex scans and measurements of AOPPs were performed on 476 participants of a cardiovascular population study. The presence of conventional cardiovascular risk factors was investigated with a questionnaire, physical examination, and laboratory tests. RESULTS: There was a positive correlation between maximum CIMT and the level of AOPPs only in the male population (r = 0.219, p = 0.033). Multivariate analysis has revealed that the association between AOPPs and mean or maximum CIMT was independent of cardiovascular risk factors (OR = 1.458, p = 0.004, and OR = 2.038, p < 0.001). CONCLUSIONS: Among males, the elevated level of AOPPs as a marker of oxidative stress may signal the existence of early atherosclerotic alterations.

Association between coronary atherosclerosis and visceral adiposity index.

BACKGROUND AND AIMS: Visceral obesity is a marker of dysfunctional adipose tissue and ectopic fat infiltration. Many studies have shown that visceral fat dysfunction has a close relationship with cardiovascular disease. For a better identification of visceral adiposity dysfunction, the visceral adiposity index (VAI) is used. Coronary artery calcium score (CACS) is known to have a strong correlation with the total plaque burden therefore provides information about the severity of the coronary atherosclerosis. CACS is a strong predictor of cardiac events and it refines cardiovascular risk assessment beyond conventional risk factors. Our aim was to evaluate the association between VAI and CACS in an asymptomatic Caucasian population. METHODS AND RESULTS: Computed tomography scans of 460 participants were analyzed in a cross-sectional, voluntary screening program. A health questionnaire, physical examination and laboratory tests were also performed. Participants with a history of cardiovascular disease were excluded from the analysis. Mean VAI was 1.41 ± 0.07 in men and 2.00 ± 0.15 in women. VAI showed a positive correlation with total coronary calcium score (r = 0.242) in males but not in females. VAI was stratified into tertiles by gender. In males, third VAI tertile was independently associated with CACS>100 (OR: 3.21, p = 0.02) but not with CACS>0 after the effects of conventional risk factors were eliminated. CONCLUSION: VAI tertiles were associated with calcium scores and the highest VAI tertile was an independent predictor for the presence of CACS>100 in males but not in females.

Novel structured MRI reporting system in neonatal hypoxic-ischemic encephalopathy - issues of development and first use experiences.

BACKGROUND AND PURPOSE: To develop an evidence-based, standardized structured reporting (SR) method for brain MRI examinations in neonatal hypoxic-ischemic encephalopathy (HIE) suitable both for clinical and research use. METHODS: SR template development was based on comprehensive review of the pertinent literature with the basic sections and subdivisions of the template defined according to MRI sequences (both conventional and diffusion-weighted, MR-spectroscopy (MRS), and T2*-weighted imaging), and the items targeted on age-related imaging patterns of HIE. In order to evaluate the usability of the proposed SR template we compared data obtained from the brain MR image analysis of 87 term and 19 preterm neonates with the literature. The enrolled 106 infants were born between 2013 and 2015, went through therapeutic hypothermia according to the TOBY criteria due to moderate to severe asphyxia and had at least one brain MRI examination within the first two weeks of life. Ethical approval was obtained for this retrospective study. Descriptive statistical analysis was also performed on data exported from the structured reporting system as feasibility test. RESULTS: The mean gestational age of the study population was 38.3±2.2 weeks; brain MRI was performed on 5.8±2.9 day of life, hence in 78% of our patients after the conclusion of therapeutic hypothermia. Our main imaging findings were concordant to the pertinent literature. Moreover, we identified a characteristic temporal evolution of diffusion changes. Interestingly 18% (n=19/106) of the clinically asphyxiated infants had isolated axial-extraaxial haemorrhage without any imaging sign of HIE. CONCLUSION: In this article our approach of reporting HIE cases with our novel SR template is described. The SR template was found suitable for reporting HIE cases, moreover it uncovered time and location dependent evolution of diffusion abnormalities (and pseudonormalization, as well), suggesting its usefulness in clinical research applications. The high number of isolated intracranial haemorrhages, and the changing diffusion pattern emphasizes the importance of early imaging in HIE.

High rate of in-stent restenosis after coronary intervention in carriers of the mutant mannose-binding lectin allele.

BACKGROUND: In-stent restenosis occurs in 10-30% of patients following bare metal stent (BMS) implantation and has various risk factors. Mannose-binding lectin (MBL) is known to have effect on the progression of atherosclerosis. Single nucleotide polymorphisms (SNP) of the MBL2 gene intron 1 (codon 52, 54, 57) are known to modulate the bioavailability of the MBL protein. Our aim was to identify the association of these polymorphisms of the MBL gene in the occurrence of in-stent restenosis after coronary artery bare metal stent implantation. METHODS: In a non-randomized prospective study venous blood samples were collected after recoronarography from 225 patients with prior BMS implantation. Patients were assigned to diffuse restenosis group and control group based on the result of the coronarography. MBL genotypes were determined using quantitative real-time PCR. Proportion of different genotypes was compared and adjusted with traditional risk factors using multivariate logistic regression. RESULTS: Average follow-up time was 1.0 (+ - 1.4) year in the diffuse restenosis group (N = 117) and 2.7 (+ - 2.5) years in the control group (N = 108). The age, gender distribution and risk status was not different between study groups. Proportion of the MBL variant genotype was 26.8% (29 vs. 79 normal homozygous) in the control group and 39.3% (46 vs. 71 normal homozygous) in the restenosis group (p = 0.04). In multivariate analysis the mutant allele was an independent risk factor (OR = 1.96, p = 0.03) of in-stent restenosis. CONCLUSIONS: MBL polymorphisms are associated with higher incidence of development of coronary in-stent restenosis. The attenuated protein function in the mutant allelic genotype may represent the underlying mechanism.

[Computer tomography examination of the coronary system - National Plaque Registry and Database, Hungary]. / A coronariarendszer komputertomográfiás vizsgálata ­ Országos Plakk Regiszter és Adatbázis (OPeRA).

INTRODUCTION AND AIM: Coronary computer tomography angiography is a unique non-invasive imaging technique with the capability to provide information regarding plaque quantity, burden and structure. A reliable registry is required to use the data of these examinations in research projects. The difficulty is that registries need double data entry simultaneously to the hospital information system. METHOD: Our registry solves this problem through a structured reporting tool, which generates clinical report and stores all data simultaneously. The automatically generated report is based on international guidelines. RESULTS: Between August 1. 2014 and September 1. 2015 we registered the data of 2866 patients. Coronary plaque was observed in 77.03% of the patients, 33.18% of the plaques were calcified. Severe stenosis was present in 13.71% of the patients. CONCLUSIONS: The structured reporting decreases reporting time, eliminates double data entry related errors. Our goal is to initiate a nationwide, unified registry, the National Plaque Registry and Database. Orv. Hetil., 2017, 158(3), 106-110.

[Hypothermia treatment in asphyxiated neonates - a single center experience in Hungary]. / Terápiás hypothermia alkalmazása az asphyxiás újszülöttek kezelésében ­ egy hazai neonatológiai centrum eredményei.

INTRODUCTION AND AIM: We aimed to analyze patient characteristics of term neonates with hypoxic-ischemic encephalopathy treated with hypothermia at the 3rd level Neonatal Intensive Care Unit of the 1st Department of Pediatrics, Semmelweis University. METHOD: We conducted a retrospective cohort analysis between 2013-2015, including 97 asphyxiated neonates with HIE who received hypothermia treatment, using our in-house developed novel registry database. RESULTS: 59.8% of neonates were born with Cesarean section and the first blood gas analysis showed a pH of 7.0 ± 0.2, pCO2 55.9 ± 27.3 mmHg, base deficit 16.7 ± 7.2 mmol/l, and lactate levels of 13.3 ± 4.7 mmol/l (x ± SD). Hypothermia treatment was started during neonatal transport in 93.7% of the cases, at 2.5 ± 0.3 hours of age. Multiorgan failure associated with the perinatal asphyxia was present in 83.2% of the patients. Patients received intensive therapy for a median of 10.8 days, 61.3% of neonates were discharged home directly, 32.2% required further hospital treatment, and 6.5% died. CONCLUSION: Our novel registry database allowed for a quick, user-friendly and time-efficient analysis of patient characteristics in neonates with HIE. This registry could aid institutional audit work and prospective clinical data collection. Orv. Hetil., 2017, 158(9), 331-339.

The ratio of the neutrophil leucocytes to the lymphocytes predicts the outcome after cardiac resynchronization therapy.

AIMS: The low lymphocyte counts and high neutrophil leucocyte fractions have been associated with poor prognosis in chronic heart failure. We hypothesized that the baseline ratio of the neutrophil leucocytes to the lymphocytes (NL ratio) would predict the outcome of chronic heart failure patients undergoing cardiac resynchronization therapy (CRT). METHODS AND RESULTS: The qualitative blood counts and the serum levels of N-terminal of the prohormone brain natriuretic peptide (NT-proBNP) of 122 chronic heart failure patients and 122 healthy controls were analysed prospectively in this observational study. The 2-year mortality was considered as primary endpoint and the 6-month reverse remodelling (≥15% decrease in the end-systolic volume) as secondary endpoint. Multivariable regression analyses were applied and net reclassification improvement (NRI) and integrated discrimination improvement (IDI) were calculated. The NL ratio was elevated in chronic heart failure patients when compared with the healthy controls [2.93 (2.12-4.05) vs. 2.21 (1.64-2.81), P < 0.0001]. The baseline NL ratio exceeding 2.95 predicted the lack of the 6-month reverse remodelling [n = 63, odds ratio = 0.38 (0.17-0.85), P = 0.01; NRI = 0.49 (0.14-0.83), P = 0.005; IDI = 0.04 (0.00-0.07), P = 0.02] and the 2-year mortality [n = 29, hazard ratio = 2.44 (1.04-5.71), P = 0.03; NRI = 0.63 (0.24-1.01), P = 0.001; IDI = 0.04 (0.00-0.08), P = 0.02] independently of the NT-proBNP levels or other factors. CONCLUSION: The NL ratio is elevated in chronic heart failure and predicts outcome after CRT. According to the reclassification analysis, 4% of the patients would have been better categorized in the prediction models by combining the NT-proBNP with the NL ratio. Thus, a single blood count measurement could facilitate the optimal patient selection for the CRT.

[Cardiovascular screening programme in the Central Hungarian region. The Budakalász Study]. / Cardiovascularis szuroprogram a közép-magyarországi régióban. Budakalász Vizsgálat.

INTRODUCTION: The reduction in mortality due to prevention programmes observed in some European countries is not currently reached in Hungary. Effective prevention is based on the screening of risk factors and health state of the population. AIM: The goal of this study was to develop a longitudinal, population-based screening programme in the Central Hungarian region in order to collect information on the health state and cardiovascular risk profile of the citizens and discover new potential cardiovascular risk factors. METHOD: The Budakalász Study is a self-voluntary programme involving the adult population (>20 yrs, approx. 8000 persons), and it consists of questionnaires, non-invasive tests (anthropometry, cardiac echo, carotid duplex scan, blood pressure measurement, ankle-brachial index), venous blood sample collection and laboratory tests. RESULTS: Until January, 2014, 2420 persons (30% of the population, male: 41.2%, average age 54.8 years) participated in the programme. Cardiovascular morbidity was higher in contrast to a former national survey. The number of risk factors and, therefore, 10-year cardiovascular risk were also elevated in this population. CONCLUSIONS: These findings underline the importance of screening programmes and effective therapies.

Controlling Inputter Variability in Vignette Studies Assessing Web-Based Symptom Checkers: Evaluation of Current Practice and Recommendations for Isolated Accuracy Metrics.

BACKGROUND: The rapid growth of web-based symptom checkers (SCs) is not matched by advances in quality assurance. Currently, there are no widely accepted criteria assessing SCs' performance. Vignette studies are widely used to evaluate SCs, measuring the accuracy of outcome. Accuracy behaves as a composite metric as it is affected by a number of individual SC- and tester-dependent factors. In contrast to clinical studies, vignette studies have a small number of testers. Hence, measuring accuracy alone in vignette studies may not provide a reliable assessment of performance due to tester variability. OBJECTIVE: This study aims to investigate the impact of tester variability on the accuracy of outcome of SCs, using clinical vignettes. It further aims to investigate the feasibility of measuring isolated aspects of performance. METHODS: Healthily's SC was assessed using 114 vignettes by 3 groups of 3 testers who processed vignettes with different instructions: free interpretation of vignettes (free testers), specified chief complaints (partially free testers), and specified chief complaints with strict instruction for answering additional symptoms (restricted testers). κ statistics were calculated to assess agreement of top outcome condition and recommended triage. Crude and adjusted accuracy was measured against a gold standard. Adjusted accuracy was calculated using only results of consultations identical to the vignette, following a review and selection process. A feasibility study for assessing symptom comprehension of SCs was performed using different variations of 51 chief complaints across 3 SCs. RESULTS: Intertester agreement of most likely condition and triage was, respectively, 0.49 and 0.51 for the free tester group, 0.66 and 0.66 for the partially free group, and 0.72 and 0.71 for the restricted group. For the restricted group, accuracy ranged from 43.9% to 57% for individual testers, averaging 50.6% (SD 5.35%). Adjusted accuracy was 56.1%. Assessing symptom comprehension was feasible for all 3 SCs. Comprehension scores ranged from 52.9% and 68%. CONCLUSIONS: We demonstrated that by improving standardization of the vignette testing process, there is a significant improvement in the agreement of outcome between testers. However, significant variability remained due to uncontrollable tester-dependent factors, reflected by varying outcome accuracy. Tester-dependent factors, combined with a small number of testers, limit the reliability and generalizability of outcome accuracy when used as a composite measure in vignette studies. Measuring and reporting different aspects of SC performance in isolation provides a more reliable assessment of SC performance. We developed an adjusted accuracy measure using a review and selection process to assess data algorithm quality. In addition, we demonstrated that symptom comprehension with different input methods can be feasibly compared. Future studies reporting accuracy need to apply vignette testing standardization and isolated metrics.

Growth and differentiation factor-15: A link between inflammaging and cardiovascular disease.

Age-related disorders are closely linked to the accumulation of senescent cells. The senescence-associated secretory phenotype (SASP) sustains and progresses chronic inflammation, which is involved in cellular and tissue dysfunction. SASP-related growth and differentiation factor-15 (GDF-15) is an immunoregulatory cytokine that is coupled to aging and thus may have a regulatory role in the development and maintenance of atherosclerosis, a major cause of cardiovascular disease (CVD). Although the effects of GDF-15 are tissue-specific and dependent on microenvironmental changes such as inflammation, available data suggest that GDF-15 has a significant role in CVD. Thus, GDF-15 is a promising biomarker and potential therapeutic target for atherosclerotic CVD.

Association of growth and differentiation factor-15 with coronary artery calcium score and ankle-brachial index in a middle-aged and elderly Caucasian population sample free of manifest cardiovascular disease.

Growth and differentiation factor-15 (GDF-15) is a stress-associated cytokine of the transforming growth factor-ß superfamily. The inflammatory and angiogenic effects of GDF-15 in atherosclerosis are controversial, and its correlation with the long asymptomatic phase of the disease is not well understood. Coronary artery calcium score (CACS) and ankle-brachial index (ABI) are sensitive markers of subclinical atherosclerosis. To date, only a few studies have examined the impact of GDF-15 on coronary artery calcification, and the association between GDF-15 and ABI has not been evaluated. Therefore, we aimed to investigate the possible relationship between serum GDF-15 concentrations and CACS and ABI in a Caucasian population sample of middle-aged (35-65 years) and elderly (> 65 years) people. In addition to recording demographic and anthropometric characteristics, atherosclerotic risk factors, and laboratory tests including serum HDL-cholesterol, LDL-cholesterol, hemoglobin A1c (HbA1c), high-sensitivity C-reactive protein, and N-terminal pro-B-type natriuretic peptide (NT-proBNP); GDF-15 level, cardiac computed tomography, and ABI measurements were also performed. A total of 269 asymptomatic individuals (men, n = 125; median age, 61.5 [IQR, 12.7] years) formed the basis of this study. Participants were divided into two groups according to their age (middle-aged, n = 175 and elderly, n = 94). Hypertension and diabetes mellitus were significantly more prevalent and CACS values and HbA1c, NT-proBNP, and GDF-15 levels were significantly higher (all p < 0.001) in the elderly group compared to the middle-aged group. Multivariate ridge regression analysis revealed a significant positive association between GDF-15 and CACS (middle-aged group: ß = 0.072, p = 0.333; elderly group: ß = 0.148, p = 0.003), and between GDF-15 and ABI (middle-aged group: ß = 0.062, p = 0.393; elderly group: ß = 0.088, p = 0.041) only in the elderly group. Our results show that GDF-15 is not only a useful biomarker of inflammation but can also predict early signs of asymptomatic atherosclerosis, especially in elderly people with chronic systemic inflammation associated with aging (inflammaging).

Non-invasive assessment of left ventricular contractility by myocardial work index in veno-arterial membrane oxygenation patients: rationale and design of the MIX-ECMO multicentre observational study.

Introduction and aims: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is an increasingly utilized therapeutic choice in patients with cardiogenic shock, however, high complication rate often counteracts with its beneficial cardiopulmonary effects. The assessment of left ventricular (LV) function in key in the management of this population, however, the most commonly used measures of LV performance are substantially load-dependent. Non-invasive myocardial work is a novel LV functional measure which may overcome this limitation and estimate LV function independent of the significantly altered loading conditions of VA-ECMO therapy. The Usefulness of Myocardial Work IndeX in ExtraCorporeal Membrane Oxygenation Patients (MIX-ECMO) study aims to examine the prognostic role of non-invasive myocardial work in VA-ECMO-supported patients. Methods: The MIX-ECMO is a multicentric, prospective, observational study. We aim to enroll 110 patients 48-72 h after the initiation of VA-ECMO support. The patients will undergo a detailed echocardiographic examination and a central echocardiography core laboratory will quantify conventional LV functional measures and non-invasive myocardial work parameters. The primary endpoint will be failure to wean at 30 days as a composite of cardiovascular mortality, need for long-term mechanical circulatory support or heart transplantation at 30 days, and besides that other secondary objectives will also be investigated. Detailed clinical data will also be collected to compare LV functional measures to parameters with established prognostic role and also to the Survival After Veno-arterial-ECMO (SAVE) score. Conclusions: The MIX-ECMO study will be the first to determine if non-invasive myocardial work has added prognostic value in patients receiving VA-ECMO support.

[Relationship between cardiovascular risk assessment and health behavior in the light of psychosocial factors.] / A cardiovascularis rizikóbecslés és az egészségmagatartás kapcsolata pszichoszociális tényezok tükrében.

INTRODUCTION: Even though preventive measures have been taken to reduce cardiovascular risk, cardiovascular mortality is increasing. Cardiovascular screening can be a population strategy that contributes to the reduction of mortality over the long term when implemented in a systematic, protocol-based, expanded manner. OBJECTIVE: In this study, we examine changes in participants' health behavior between 2012 and 2019 as a follow-up to the Budakalász Epidemiological Study (BEV). METHOD: A cardiovascular health index was developed to enable effective follow-up. This study included subjects with medium and high cardiovascular risks who participated in the BEV complex cardiovascular risk assessment in 2012 (n = 502). Besides the basic data from the BEV baseline study (demographics, healthy lifestyle, risk behavior, diseases treated by medicine), the 2019 follow-up questionnaire included newly added psychological questionnaires (Perceived Stress, WHO Well-being, Beck Hopelessness Scale, Health-Related Social Support, ABCD Risk Questionnaire). RESULTS: All factors of the cardiovascular health index created in our analysis showed an improvement of over 70% between 2012 and 2019. 37.6% of the participants did something for their health, according to their confession, by 30.3%, BEV had a big or very big impact on their lives from the 2012 BEV test in the year after the test, and by 24.7%, BEV had and still has a big or very big impact on their lives. The improving health indices show a significant correlation with psychological factors. Psychological factors showed a positive correlation with well-being (tau_b = 0.344) and a negative correlation with perceived stress (tau_b = -0.225) and hopelessness (tau_b = -0.206). CONCLUSION: The participants in the study showed a significant change in health behavior seven years after the BEV cardiovascular risk assessment. A higher level of mental well-being is associated with improved values. By analyzing the impact of BEV on the health behavior change and the lifestyle, we can conclude that the cardiovascular risk assessment facilitates health behavior change.

Long-term prognostic value of left atrial longitudinal strain in an elderly community-based cohort.

Despite the well-known importance of left atrial (LA) mechanics in diastolic function, data are scarce regarding the prognostic power of LA longitudinal strain and its potential added value in the risk stratification of an elderly population. Accordingly, our aim was to determine the long-term prognostic importance of 2D speckle-tracking echocardiography-derived peak atrial longitudinal strain (PALS) in a community-based screening sample. Three hundred and fourteen volunteers were retrospectively identified from a population-based screening program (mean age 62 ± 11 years; 58% female) with a median follow-up of 9.5 years. All subjects who participated in the screening program underwent 2D echocardiography to measure left ventricular (LV) ejection fraction (EF), global longitudinal strain (GLS), and PALS, as well as low-dose cardiac CT to determine the Agatston score. The primary endpoint was all-cause mortality. Thirty-nine subjects (12.4%) met the primary endpoint. Subjects with adverse outcomes had significantly lower LV GLS (dead vs. alive; - 19.2 ± 4.3 vs. - 20.6 ± 3.5%, p < 0.05) and PALS (32.3 ± 12.0 vs. 41.8 ± 14.2%, p < 0.001), whereas LV EF did not show a difference between the two groups (51.1 ± 7.0 vs. 52.1 ± 6.2, %, p = NS). By multivariable Cox regression analysis, PALS was found to be a significant predictor of adverse outcomes independent of LV GLS, and Agatston and Framingham scores. In subjects with PALS values below the standard cut-off of 39%, the risk of all-cause mortality was almost 2.5 times higher (hazard ratio: 2.499 [95% confidence interval: 1.334-4.682], p < 0.05). Beyond the assessment of LV EF and LV GLS, PALS offers incremental value in cardiovascular risk stratification in a community-based elderly cohort. PALS was found to be a significant and independent predictor of long-term mortality among other classical cardiovascular risk estimators.

PCSK9, A Promising Novel Target for Age-Related Cardiovascular Dysfunction.

Cardiovascular diseases (CVDs) are the leading cause of death among elderly people. Proprotein convertase subtilisin/kexin type 9 (PCSK9) is an important regulator of cholesterol metabolism. Herein, we investigated the role of PCSK9 in age-related CVD. Both in humans and rats, blood PCSK9 level correlated positively with increasing age and the development of cardiovascular dysfunction. Age-related fatty degeneration of liver tissue positively correlated with serum PCSK9 levels in the rat model, while development of age-related nonalcoholic fatty liver disease correlated with cardiovascular functional impairment. Network analysis identified PCSK9 as an important factor in age-associated lipid alterations and it correlated positively with intima-media thickness, a clinical parameter of CVD risk. PCSK9 inhibition with alirocumab effectively reduced the CVD progression in aging rats, suggesting that PCSK9 plays an important role in cardiovascular aging.

Catenin Alpha 2 May Be a Biomarker or Potential Drug Target in Psychiatric Disorders with Perseverative Negative Thinking.

AlphaN-catenin gene CTNNA2 has been implicated in intrauterine brain development, as well as in several psychiatric disorders and cardiovascular diseases. Our present aim was to investigate CTNNA2 gene-wide associations of single-nucleotide polymorphisms (SNPs) with psychiatric and cardiovascular risk factors to test the potential mediating role of rumination, a perseverative negative thinking phenotype in these associations. Linear mixed regression models were run by FaST-LMM within a sample of 795 individuals from the Budakalasz Health Examination Survey. The psychiatric outcome variables were rumination and its subtypes, and ten Brief Symptom Inventory (BSI) scores including, e.g., obsessive-compulsive, depression, anxiety, hostility, phobic anxiety, and paranoid ideation. Cardiovascular outcome variables were BMI and the Framingham risk scores for cardiovascular disease, coronary heart disease, myocardial infarction, and stroke. We found nominally significant CTNNA2 associations for every phenotype. Rumination totally mediated the associations of CTNNA2 rs17019243 with eight out of ten BSI scores, but none with Framingham scores or BMI. Our results suggest that CTNNA2 genetics may serve as biomarkers, and increasing the expression or function of CTNNA2 protein may be a potential new therapeutic approach in psychiatric disorders with perseverative negative thinking including, e.g., depression. Generally, an antiruminative agent could be a transdiagnostic and preventive psychopharmacon.

Cardiovascular disease risk perception in a Hungarian community sample: psychometric evaluation of the ABCD Risk Perception Questionnaire.

OBJECTIVES: Reliable and valid assessment of subjective risk perception is a crucial part of cardiovascular disease (CVD) prevention and rehabilitation. Since the recently developed Attitudes and Beliefs about Cardiovascular Disease (ABCD) Risk Questionnaire complies with these requirements, the aim of the present study was to investigate the psychometric properties of the Hungarian version of the measure. DESIGN AND SETTING: Community-based cross-sectional observational study PARTICIPANTS: In sum, 410 (M=49.53 years, SD=8.09) Hungarian adults (inclusion criteria: aged 35 and above, not under treatment with a psychiatric disorder) were included in the present study (female: n=277, 67.6%; college or university-level education: n=247, 60.2%). METHODS: We translated the ABCD Risk Questionnaire into Hungarian and checked its psychometric properties and validity indices. PRIMARY OUTCOME MEASURES: Internal consistency, explorative and confirmative factorial validity. Associations with sociodemographic and health-related characteristics, as well as with measures of mental health (depressive symptoms, perceived stress and well-being). RESULTS: Exploratory and confirmatory factor analyses supported a three-factor solution, corresponding to the original subscales of Risk Perception, Perceived Benefits and Healthy Eating Intentions, with a moderate correlation between the latent constructs. The respondents' level of knowledge on CVD risk factors was largely independent of their subjective risk perception. The results also provided evidence on the weak-to-medium associations between mental health indices and CVD-related perceptions. Based on the results, a shortened scale version was also suggested. CONCLUSION: This study confirms the factorial structure, internal consistency and validity of the Hungarian version of the ABCD Risk Questionnaire in a non-English-speaking community sample. The ABCD Risk Perception Questionnaire is a parsimonious and psychometrically adequate measure to assess CVD-related attitudes and knowledge in the general population. Further research is needed in socioeconomically more diverse and in clinical samples, as well as in longitudinal intervention studies.

[Correlation of social support and healthy lifestyle]. / A társas támogatás és az egészséges életmód összefüggései.

Introduction: Cardiovascular disease is the leading cause of death accounting for 4 million deaths per year in Europe. Psychosocial factors explain at least 25-40% of the disease's prevalence beyond the well-known lifestyle factors. Isolation in adulthood is one of the main sources of chronic stress that raises the incidence of the disease. The low level of social support and social isolation are increasing the risk of depression and high blood pressure hence the incidence of cardiovascular diseases. Aim: Our aim was to observe the correlation between social isolation and health behaviour. Furthermore, we have adapted the earlier validated Multidimensional Social Support Scale to the domain of health. Method: The data from 507 persons were collected online in 2018. Multidimensional Social Support Scale adapted to health, self-rated health, subjective means, short version of Beck Depression, shortened version of WHO Wellbeing, and Perceived Stress Scales were recorded. Results: Factor analysis verified the scale construction of the original 3-subscale structure (Cronbach alpha values = 0.945, 0.950 and 0.905). According to the regression models, social support received from friends we have observed to have moderately positive correlation with intensive exercises (B = 0.205, beta = 0.096, p = 0.093). Logistic regression model revealed that health-connected social support does not correlate with smoking, only education variable was related with it strongly, statistically significantly (B = -1.284, OR = 0.277, p<0.001). Conclusion: Multidimensional Social Support Scale has satisfactory stability and consistency to measure health-related social support. Social support showed correlation with the measures of mental health (depression, stress-level, wellbeing), and moderate association with intense exercises. Orv Hetil. 2020; 161(4): 129-138.
