Abstract Objectives This narrative review aims to update the current evidence and offer insight into new non-invasive ultrasound techniques used early identify degenerative vascular changes in subjects with periodontitis investigate if these methodologies could be useful subclinical cardiovascular disease (CVD) dysfunction patients monitor CVD risk after periodontal treatment. Methods Studies examining assessment of endothelial function through latest were analyzed. Systematic reviews, observational studies, clinical trials English language identified using PubMed, Web Science, Google Scholar databases key search terms such as “periodontitis,” “endothelial (ED),” “arterial stiffness,” “periodontal therapy.” Results Several mechanisms are involved association between CVD. The players bacteria their toxins, which can enter circulation infiltrate blood vessel walls. increase proinflammatory molecules interleukins chemokines, c-reactive protein, fibrinogen, oxidative stress also plays a decisive role. In addition, an parameters ED, arterial stiffness, atherosclerosis, carotid intima-media thickness, pulse wave velocity, flow-mediated dilatation, has been shown patients. Conclusions literature today agrees on positive role therapy systemic inflammatory indices outcomes. Hopefully, extended provide comprehensive understanding CVD-periodontitis link from perspective personalized medicine approach periodontology.

Abstract Treatment of classic congenital adrenal hyperplasia (CAH) is directed at replacing deficient hormones and reducing androgen excess. However, even in the era early diagnosis lifelong hormonal substitution, presence CAH still associated with numerous complications also increased mortality. The aim this article was to create an authoritative balanced review concerning cardiometabolic risk patients CAH. authors searched all major databases scanned reference lists potentially eligible articles find relevant articles. compared that other forms insufficiency. reviewed articles, most which were published recently, provided conflicting results, can be partially explained by differences inclusion criteria treatment, small sample sizes, gene–environment interactions. many studies showed weight gain, worsening insulin sensitivity, high blood pressure, endothelial dysfunction, atherosclerotic changes vascular wall, left ventricular diastolic dysfunction. These more consistently reported than nonclassic part related functional abnormalities disorder and/or impact overtreatment undertreatment. An analysis available suggests individuals are risk. Excess cardiovascular metabolic morbidity likely multifactorial, glucocorticoid overtreatment, imperfect hormone replacement therapy, excess, adrenomedullary failure. Cardiometabolic effects new therapeutic approaches require future targeted studies.

Flow-mediated dilation (FMD) is a noninvasive method to evaluate vascular endothelial function, which manifests the inflammatory response, cell proliferation, and autoregulation. Since FMD assesses commonly in brachial artery by ultrasound, compared other invasive methods such as optical coherence tomography (OCT) intravascular ultrasound (IVUS), it widely used function allows serial assessment. In this review, we present currently accepted mechanisms of measurement with studies applied current clinical practice using FMD. After all, association cardiovascular diseases substance, so introduce related disease diabetes, hyperlipidemia, chronic kidney disease, coronary peripheral disease. addition, pregnancy COVID-19 were also inspected. Yet, examination not endorsed prevention measure, for lack clear standardized value methodology. Still, many recommend practicable would be better prognostic prognosis future research.

Cardiovascular diseases (CVDs) are one of the most critical public health problems in contemporary world because they leading cause morbidity and mortality. Diabetes mellitus (DM) is substantial risk factors for developing CVDs. Glycated hemoglobin a product non-enzymatic glycation present erythrocytes. The determination percentage glycated (HbA1c) commonly used clinical practice to assess glycemic control patients diagnosed with DM. This method much more informative than repeated blood glucose tests, HbA1c value reflects degree over last three months. It is, therefore, not surprising that correlates presence severity diabetes complications, including CVDs, population diabetic patients. purpose this publication was results literature review on relationship between people without DM, subclinical cardiovascular dysfunction, clinically overt important tools dysfunction included measurement intima-media thickness (IMT), especially carotid IMT (cIMT), arterial stiffness assessment by pulse wave velocity (PWV), ankle–brachial index (ABI).
