Abstract
BACKGROUND The interrelation between COVID-19 and various cardiovascular and metabolic disorders has been a critical area of study. There is a growing need to understand how comorbidities such as cardiovascular diseases (CVDs) and metabolic disorders affect the risk and severity of COVID-19. OBJECTIVE The objective of this study is to systematically analyze the association between COVID-19 and cardiovascular and metabolic disorders. The focus is on comorbidity, examining the roles of CVDs such as embolism, thrombosis, hypertension, and heart failure, as well as metabolic disorders such as disorders of glucose and iron metabolism. METHODS Our study involved a systematic search in PubMed for literature published from 2000 to 2022. We established 2 databases: one for COVID-19-related articles and another for CVD-related articles, ensuring all were peer-reviewed. In terms of data analysis, statistical methods were applied to compare the frequency and relevance of MeSH (Medical Subject Headings) terms between the 2 databases. This involved analyzing the differences and ratios in the usage of these terms and employing statistical tests to determine their significance in relation to key CVDs within the COVID-19 research context. RESULTS The study revealed that "Cardiovascular Diseases" and "Nutritional and Metabolic Diseases" were highly relevant as level 1 Medical Subject Headings descriptors in COVID-19 comorbidity research. Detailed analysis at level 2 and level 3 showed "Vascular Disease" and "Heart Disease" as prominent descriptors under CVDs. Significantly, "Glucose Metabolism Disorders" were frequently associated with COVID-19 comorbidities such as embolism, thrombosis, and heart failure. Furthermore, iron deficiency (ID) was notably different in its occurrence between COVID-19 and CVD articles, underlining its significance in the context of COVID-19 comorbidities. Statistical analysis underscored these differences, highlighting the importance of both glucose and iron metabolism disorders in COVID-19 research. CONCLUSIONS This work lays the foundation for future research that utilizes a knowledge-based approach to elucidate the intricate relationships between these conditions, aiming to develop more effective health care strategies and interventions in the face of ongoing pandemic challenges.

Prediction model for leaflet thrombosis in patients undergoing transcatheter aortic valve implantation: the EFFORT study. Clin Res Cardiol 2024:10.1007/s00392-024-02486-3. [PMID: 39012508 DOI: 10.1007/s00392-024-02486-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2024] [Accepted: 06/24/2024] [Indexed: 07/17/2024]
Abstract
BACKGROUND Leaflet thrombosis (LT) is a multifaceted and underexplored condition that can manifest following transcatheter aortic valve implantation (TAVI). The objective of this study was to formulate a prediction model based on laboratory assessments and clinical parameters, providing additional guidance and insight into this relatively unexplored aspect of post-TAVI complications. METHODS The present study was an observational prospective hypothesis-generating study, including 101 patients who underwent TAVI and a screening for LT (the primary endpoint) by multidetector computed tomography (MDCT). All images were acquired on a third-generation dual-source CT system. Levels of von Willebrand factor (vWF) activity, hemoglobin (Hb), and lactate dehydrogenase (LDH) were measured among other parameters. A predictive score utilizing binary logistic regression, Kaplan-Meier time-to-event analysis, and receiver operating characteristics (ROC) analysis was established. RESULTS LT (11 subclinical and 2 clinical) was detected in 13 of 101 patients (13%) after a median time to screening by MDCT of 105 days (IQR, 98-129 days). Elevated levels of vWF activity (> 188%) pre-TAVI, decreased Hb values (< 11.9 g/dL), as well as increased levels of LDH (> 312 U/L) post-TAVI and absence of oral anticoagulation (OAC) were found in patients with subsequent LT formation as compared to patients without LT. The established EFFORT score ranged from - 1 to 3 points, with an increased probability for LT development in patients with ≥ 2 points (85.7% of LT cases) vs < 2 points (14.3% of LT cases; p < 0.001). Achieving an EFFORT score of ≥ 2 points was found to be significantly associated with a 10.8 times higher likelihood of developing an LT (p = 0.001). The EFFORT score has an excellent c-statistic (area under the curve (AUC) = 0.89; 95% CI 0.74-1.00; p = 0.001) and a high negative predictive value (98%). CONCLUSION An EFFORT score might be a helpful tool to predict LT development and could be used in risk assessment, if validated in confirmatory studies. Therefore, the score has the potential to guide the stratification of individuals for the planning of subsequent MDCT screenings.

Abstract
To delineate prevalence of stroke in the pediatric intensive care unit and to determine risk factors for stroke and association of stroke with mortality in patients with congenital heart disease. Retrospective cohort study. Patients admitted to pediatric intensive care units in the USA participating in the Pediatric Health Information System database from 2016 to 2021. Patients were categorized as those who experienced ischemic or hemorrhagic stroke and those with congenital heart disease. We performed univariate and multivariate logistic regressions to determine risk factors associated with stroke and then developed a predictive model for stroke development in patients with congenital heart disease. Of 426,029 admissions analyzed, 4237 (0.9%) patients experienced stroke and 1197 (1.4%) of 80,927 patients with congenital heart disease developed stroke (odds ratio 1.15, 95% confidence interval 1.06-1.24). Patients with congenital heart disease, younger age, extracorporeal membrane oxygenation, mechanical ventilation, and cardiac arrest were most strongly associated with increased risk of stroke. Stroke increased odds of mortality for patients with congenital heart disease (odds ratio 2.49, 95% confidence interval 2.08-2.98). A risk score greater than 0 was associated with a 33.3% risk of stroke for patients with congenital heart disease (negative predictive value of 99%, sensitivity 69%, specificity 63%). Children with congenital heart disease are at increased risk for developing stroke, which is associated with increased mortality. Early identification of the most vulnerable patients may enable providers to implement preventative measures or rapid treatment strategies to prevent neurologic morbidity.

Abstract
Von Hippel-Lindau protein (VHL) is essential to hypoxic regulation of cellular processes. VHL promotes proteolytic clearance of hypoxia-inducible transcription factors (HIFs) that have been modified by oxygen-dependent HIF-prolyl hydroxylases. A homozygous loss-of-function VHLR200W mutation causes Chuvash erythrocytosis, a congenital disorder caused by augmented hypoxia-sensing. Homozygous VHLR200W results in accumulation of HIFs that increase transcription of the erythropoietin gene and raise hematocrit. Phlebotomies reduce hematocrit and hyperviscosity symptoms. However, the major cause of morbidity and mortality in Chuvash erythrocytosis is thrombosis. Phlebotomies cause iron deficiency, which may further elevate HIF activity and transferrin, the HIF-regulated plasma iron transporter recently implicated in thrombogenesis. We hypothesized that transferrin is elevated in Chuvash erythrocytosis, and that iron deficiency contributes to its elevation and to thrombosis. We studied 155 patients and 154 matched controls at steady state and followed them for development of thrombosis. Baseline transferrin was elevated, and ferritin reduced in patients. VHLR200W homozygosity and lower ferritin correlated with higher erythropoietin and transferrin. During 11 years of follow-up, risk of thrombosis increased 8.9-fold in patients versus controls. Erythropoietin elevation, but not hematocrit or ferritin, correlated with thrombosis risk. Unexpectedly, transferrin elevation associated with reduced rather than increased thrombosis risk. The A allele of the promoter EPO single nucleotide polymorphisms (SNP), rs1617640, associated with elevated erythropoietin and increased thrombosis risk, whereas the A allele of the intronic TF SNP, rs3811647, associated with higher transferrin and protection from thrombosis in patients. Our findings suggest an unexpected causal relationship between increased transferrin and protection from thrombosis in Chuvash erythrocytosis.

Abstract
Retinal vein occlusion (RVO) is the second most common retinal disorder. In comparison to diabetic retinopathy or age-related macular degeneration, RVO is usually an unexpected event that carries a greater psychological impact. There is strong evidence to suggest that cardiovascular diseases are the most common risk factors in this pathology and it has long been known that a higher consumption of fish, nuts, fruits, and vegetables has a protective effect against these types of conditions. In the last several years, interest in plant-based diets has grown in both the general population and in the scientific community, to the point to which it has become one of the main dietary patterns adopted in Western countries. The aim of this review is to investigate the potential impact of macro- and micronutrients on retinal vein occlusion.

Abstract
OBJECTIVES To study the causes of iron deficiency, laboratory findings and clinical manifestation of infants aged 6-12 months and children aged 1-3 years diagnosed with severe iron-deficiency anemia. PATIENTS, MATERIALS AND METHODS We conducted an observational, retrospective single tertiary center study between January 2015 and April 2022, which included 142 children. The control group (patients with no diagnosis of severe iron-deficiency anemia) included 71 patients and the study group (patients diagnosed with severe iron-deficiency anemia) included also 71 patients. Clinical data were retrospectively collected from hospital medical records. Statistical analysis was conducted using Statistical Package for the Social Sciences (SPSS) 25.0 software. RESULTS Seventy-one children had hemoglobin <7 g∕dL and low values of ferritin/serum iron (22 infants aged 6-12 months and 49 children aged 1-3 years). In both the study and control groups, the male gender was slightly more prevalent. Mother's age at birth and living standard is significantly lower in the study group. We note a higher frequency of premature births (14.08%) in children identified with anemia compared to control group (8.45%). We found a statistically significant distribution of cow's milk consumption among the two groups (p<0.001). Pearson's correlation test revealed a significant positive correlation, indicating that anemia is directly proportional to cow's milk consumption. CONCLUSIONS The most frequent cause of iron-deficiency anemia in infants and children 1-3 years old was the consumption of cow's milk following incorrect diversification and incomplete prophylaxis of iron-deficiency anemia.
