The metabolic syndrome is a combination of several metabolic disorders, such as cardiovascular disease, atherosclerosis, and type 2 diabetes. Lifestyle modifications, including quitting smoking, are recommended to reduce the risk of metabolic syndrome and its associated complications. Not much research has been conducted in the field of e-cigarettes and the risk of metabolic syndrome. Furthermore, taking into account the influence of e-cigarettes vaping on the individual components of metabolic syndrome, i.e, abdominal obesity, insulin resistance, dyslipidemia and elevated arterial blood pressure, the results are also ambiguous. This article is a review and summary of existing reports on the impact of e-cigarettes on the development of metabolic syndrome as well as its individual components. A critical review for English language articles published until 30 June 2020 was made, using a PubMed (including MEDLINE), Cochrane, CINAHL Plus, and Web of Science data. The current research indicated that e-cigarettes use does not affect the development of insulin resistance, but could influence the level of glucose and pre-diabetic state development. The lipid of profile an increase in the TG level was reported, while the influence on the level of concentration of total cholesterol, LDL fraction, and HDL fraction differed. In most cases, e-cigarettes use increased the risk of developing abdominal obesity or higher arterial blood pressure. Further research is required to provide more evidence on this topic.

The roles of the autonomic nervous system, vasopressin, and angiotensin II in support of blood pressure were evaluated in seven conscious, resting dogs while hydrated or dehydrated. Mean arterial blood pressure (MAP) was monitored, and the dogs were given hexamethonium to block autonomic ganglia. Thirty minutes later, they were given captopril, and after another 30 min, a vasopressin V1 antagonist, d(CH2)5TyrMeAVP, was given. The order okf administration of captopril and d(CH2)5TyrMeAVP was alternated in different experiments. Hexamethonium had no effect on steady-state MAP in either hydrated or dehydrated dogs. In hydrated dogs, the average MAP was 100 mmHg; d(CH2)5TyrMeAVP decreased MAP by approximately 12 mmHg, and captopril decreased MAP by 24 mmHg. The magnitude of the effect of these two inhibitors was independent of the order of their administration. Dehydration doubled the effect of d(CH2)5TyrMeAVP on MAP but had no effect on the response to captopril. The results suggest that 1) autonomic function is not essential for maintenance of arterial blood pressure in resting dogs; 2) during autonomic ganglionic blockade, arterial blood pressure is supported by both angiotensin II and vasopressin; and 3) dehydration increases the role of vasopressin in control of blood pressure.

Abstract Many studies have shown that systolic and diastolic arterial blood pressure changes due tohigher weight in both school-age children and in adolescents. Abnormalities of thyroid functionmight be no less important factor in relation to metabolic syndrome. The objective of the studywas to determine the relationship of arterial blood pressure, glucose, adiponectin and thyroidfunction parameters to major risk factors of metabolic syndrome. The risk factors tested werebody mass index (BMI) and waist circumference in female students aged 18 to 25 years. Westudied 105 RSU Red Cross college students aged 18 to 25 years. We calculated their BMI, lungvital capacity (ml), thyroid changes by ultrasound (USG) (27 students) and ECG (79 students). Inaddition, we measured their waist and chest circumferences, and systolic and diastolic bloodpressure in both arms. We determined concentration of glucose, adiponectin, thyroid stimulatinghormone (TSH) and free thyroxine (FT4) in blood. Statistical analyses were performed using theSPSS 15.01 package software. There was a statistically significant positive correlation betweenthe arterial blood pressure, BMI and increase of the waist circumference in students (average age20.7 years). The average arterial blood pressure in students was normal. The age at the onset ofmenarche had a significant positive effect on diastolic arterial blood pressure (P = 0.009-0,017).An increase in blood glucose concentration was closely associated with BMI (P = 0.03) and waistcircumference (P = 0.045). However, adiponectin concentration was correlated with systolic (P =0.007-0.048) and diastolic (P = 0.002-0.003) blood pressure. Significant ECG changes werefound in 10% of the subjects, indicating cardiovascular changes in these young women. Thehigher the FT4 and TSH concentrations, the more frequently were observed changes in the ECGST-segment (P = 0.01-0,008). A significant relationship between diastolic blood pressure and theage at onset of menarche (P = 0.009-0.017) was found. Increased arterial blood pressure wasassociated with an increase in BMI, waist circumference and adiponectin concentration, while anincrease in blood glucose concentration was associated with increased BMI and waist circumference,but not with the adiponectin level. Changes in ECG and increased diastolic arterial bloodpressure in relation to menarche indicate a possible role of the endocrine system and genetic factorsin regulation of the main parameters of metabolic syndrome
