Increase of renal resistive index and mineral metabolism disorder in patients with acute coronary syndrome with preserved renal function.

OBJECTIVE: Coronary artery disease is one of the first causes of death in the Western world; for this reason, it is essential to identify new, systemic, non-invasive and low-cost cardiovascular risk markers. The acute coronary syndrome includes ST-Elevation Myocardial Infarction (STEMI) and Non-ST-Elevation Myocardial Infarction (NSTEMI), based on ECG findings. We aimed to evaluate Renal Resistive Index (RRI) as a marker of cardiovascular risk and assess the associations with other cardiovascular risk factors (metabolic indexes, mineral metabolism disorders and endothelial dysfunction and atherosclerosis markers) in STEMI and NSTEMI patients. PATIENTS AND METHODS: Clinical, laboratory and instrumental examinations as metabolic and inflammation indexes, markers of atherosclerosis and endothelial dysfunction (renal function, mineral metabolism disorders, inflammation indexes, Intima Media Thickness (IMT), Ankle Brachial Pressure Index, Left Ventricular Mass Index, Relative Wall Thickness) were performed. RESULTS: Eighty-one patients with STEMI and NSTEMI were enrolled. We showed a significant positive correlation between RRI and age (p<0.01), intact parathyroid hormone (p<0.01) and IMT (p<0.01), as well as a significant negative correlation between RRI and body surface area (BSA) (p=0.02), estimated Glomerular Filtration Rate (eGFR) (p<0.01), serum calcium (p<0.01) and 25-hydroxy-vitamin D (p=0.03). Moreover, we found a significant correlation between RRI and male patients (p<0.01), coronary artery disease history (CAD) (p=0.049), hypertension (p=0.025) and left ventricular eccentric hypertrophy (LVEH) (p=0.047). CONCLUSIONS: Our study showed an association between RRI and the main traditional and non-traditional cardiovascular risk factors involved in atherosclerosis pathogenesis, such as age, BSA, hypertension, male sex, CAD history, mineral metabolism disorders and LVEH, in patients with preserved renal function. Moreover, we found a significant correlation between RRI and eGFR, suggesting that RRI could be useful in the evaluation of both renal function and progression of renal damage, even in an early stage with a conserved or only slightly reduced kidney function. We also showed a significant correlation with some markers of systemic atherosclerosis such as IMT and LVEH. For a more precise assessment of prognosis and cardiovascular risk in patients with high cardiovascular mortality, we suggest performing a systematic RRI evaluation, considering the non-invasive nature of the procedure, its reproducibility, easy execution, and low costs.

Dentition Patterns in Different Unilateral Cleft Lip Subphenotypes.

Oral clefts play an essential role in disturbed odontogenesis of the deciduous and permanent dentition, yet little is known about this relationship. We investigated, within the categories cleft lip with or without alveolus (CL ± A) and cleft lip, alveolus and palate (CLAP), whether different CL subphenotypes based on morphological severity of the cleft show different dentition patterns and whether a more detailed subdivision of the incomplete CL has clinical relevance. In this retrospective study, 345 children with nonsyndromic unilateral CL ± A and CLAP from the Dutch Association for Cleft Palate and Craniofacial Anomalies (NVSCA) registry were included to assess the association between the CL subphenotypes and lateral incisor patterns. Five different deciduous and permanent patterns of the lateral incisor were distinguished: located in normal position (pattern z/Z), in the anterior segment (pattern x/X) or in the posterior segment of the cleft (pattern y/Y), one in each segment of the cleft (pattern xy/XY), and agenesis of the lateral incisor (pattern ab/AB). Analyses were performed by using multinomial logistic regression models. Children born with a vermillion notch or a one-third to two-thirds CL were most likely to have a deciduous pattern x and a permanent pattern X, while children born with a two-thirds to subtotal CL were most likely to have deciduous pattern xy and a permanent pattern X compared to children with a complete CL that predominantly had deciduous pattern y and a permanent pattern AB. Based on the relationship of the CL morphology with the deciduous dentition, subdivision of the CL morphology into vermillion notch to two-thirds CL, two-thirds to subtotal CL, and complete CL appears to be an optimal subdivision. Our results indicate that a more detailed subdivision of the CL has clinical relevance and that critical factors in the pathogenesis of the CL are also critical for the odontogenesis.
