Polycystic ovary syndrome (PCOS) is one of the hormonal disorders in women. The PCOS may be due to decreased aromatase activity in adipose tissue. The aim of this study was to investigate the differences in the expression of aromatase protein in adipose tissue of pregnant women with and without PCOS.

In this case-control study, aromatase protein expression were compared in subcutaneous adipose tissue of 11 pregnant women with and 11 without PCOS who were matched with each other in terms of weight characteristics before pregnancy and age. A subcutaneous adipose tissue samples (3-4 grams) was obtained during cesarean section. The expression of aromatase protein in adipose tissue was assessed using Western blotting method. All obtained data were statistically analyzed using SAS software.

According to the analysis and quantification of the results, it was shown that the expression of aromatase protein in the subcutaneous adipose tissue of the abdomen of the group with PCOS decreased significantly compared to the non-PCOS group (P = 0.006). In other words, the expression of aromatase protein was about one-third lower in the adipose tissue of women with PCOS than in women without it.</div>

The current study shows that the expression of aromatase protein in the adipose tissue of women with PCOS is reduced. This finding could confirm the key role of adipose tissue in the development of symptoms of this syndrome.

Contrast-induced acute kidney injury (CI-AKI) is an important issue in patients who are candidate for using contrast media in order to do diagnostic and therapeutic imagining. This study aimed to investigate the effect of rosuvastatin on the development of contrast-induced acute kidney injury in patients with chronic kidney disease performing computed tomography (CT) scan with contrast media.

In this clinical trial study, 402 patients with chronic kidney disease who underwent CT scan with contrast in Alzahra hospital, Isfahan, Iran, during the years 2018-2019 were studied. Patients were divided into two groups, patients in the first group received 20 mg rosuvastatin 24 hours prior to CT scan and 10 mg rosuvastatin tablets daily for two consecutive days. The second group received the placebo.

 There was a significant difference in creatinine and glomerular filtration rate (eGFR) after CT scan (P < 0.050). The mean of creatinine was lower, and the mean of eGFR was higher in the intervention group than placebo after the intervention (P < 0.050). The frequency of contrast-induced acute kidney injury in the intervention group was 1%, and in the placebo group was 4% (P = 0.059).

Rosuvastatin can reduce the risk of contrast-induced acute kidney injury after using contrast media, including increase in creatinine, and decrease in eGFR.

Tracheal intubation can result in extensive changes in heart rate and blood pressure. The aim of this study was to investigate the effect of smearing tracheal tube cuff with diltiazem gel on cardiovascular changes in patients who underwent laparoscopic cholecystectomy surgery.

This clinical trial study was conducted on 80 patients who underwent laparoscopic cholecystectomy surgery in Imam Reza hospital, Kermanshah, Iran. Patients were randomly divided in two groups of intervention (tracheal tube cuff smeared with 2% diltiazem gel) and control (tracheal tube cuff smeared with sterile water-soluble lubricant gel) using permuted block technique. Cardiovascular changes (heart rate, systolic blood pressure, diastolic blood pressure, and dysrhythmia) was measured before the surgery, and immediately and 5 minutes after intubation, every 15 minutes during the surgery, at the beginning of the recovery, and 15 and 30 minutes after entering the recovery.

The mean heart rate, systolic blood pressure, and diastolic blood pressure in patients receiving diltiazem gel was significantly decreased compared to control group (P < 0.050). Moreover, according to the results of repeated measures ANOVA, in the group receiving diltiazem gel, the mean of measured variables showed a significant difference in various times (P < 0.050).

 Regarding the effect of smearing tracheal tube cuff with diltiazem gel on decreasing cardiovascular changes, diltiazem gel can be used to prevent mentioned responses or to suppress them.
