Comparison between electronic cigarette refill liquid and nicotine on metabolic parameters in rats.

Aims: Nicotine is known to promote body weight loss and to disturb glucose homeostasis and lipoprotein metabolism. Electronic cigarettes, as a substitute to nicotine, are becoming increasingly popular, although there is no evidence regarding their safety. Considering the dearth of information about e-cigarette toxicity, the present study was designed to compare nicotine alone to e-liquid with or without nicotine on metabolic parameters in Wistar rats.

Serum lipid level in Tunisian patients with psoriasis.

Background: Psoriasis is a common chronic inflammatory skin disorder that has been associated with oxidative stress, abnormal plasma lipid metabolism, and high frequency of cardiovascular events. The aim of this study was to determine lipid profile variations in Tunisian psoriatic patients.

Methods: This study was designed and conducted as a case-control assay with 91 psoriatic patients and 91 controls.

Psoriasis is associated with increased Framingham ten-year risk score for coronary heart disease in Tunisians.

Background: To assess the ten-year cardiovascular risk for coronary heart disease (CHD) in psoriatic patients and to test the impact of psoriasis severity and duration on cardiovascular risk.

Methods: A case-control study included 202 adult psoriatic patients and 202 controls.

Results: Risk CHD was estimated using the Framingham risk score algorithm.
