[ effect of resistance and combined exercise on serum levels of liver enzymes and fitness indicators in women with nonalcoholic fatty liver disease]

Background and Aim: Nonalcoholic fatty liver disease is the most common cause of abnormal liver enzymes. We aimed to investigate the effects of resistance and combined exercise on levels of liver enzymes in women with fatty liver disease

Materials and Methods: In this study, 37 women were assigned into three groups including control, resistance and combined exercise groups. Resistance exercise protocol included 8 movements, 3 sets, 8-10 repetitions which performed at%60-75 of one repetition maximum¡ 3 times per week for 8 weeks. Combined exercise included 4 resistance movement in the first half of training session and the aerobic exercise at intensity of%60-75 maximum heart rate in the other half. The AST, ALT and ALP were measured using biochemical methods. Paired t-test results for the extraction of one-way ANOVA, at a significant level of 0/05 were analysed

Results: The level of ALP only in the resistance exercise group significantly decreased [p=0.03], but AST and ALT levels did not significantly change in any groups [p>0.05]. The mean of ALT/AST ratio significantly increased in the resistance exercise group [p =0.04], but no significant changes were observed in the combination and control groups. The mean of flexibility [p=0.001], maximal oxygen consumption [p=0.02], muscle strength [p=0.003] and grip strength [p=0.001], significantly increased after resistance exercise

Conclusion: None of the resistance and combined exercises had significant effect on the levels of AST and ALT, but the resistance exercise improved ALP and fitness indicators. Therefore, resistance exercise may be more favorite for fatty liver patients

Aortic dissection: unusual and rare complication during subclavian vein catheterization in a hemodialysis patient

We present a 56-year-old female with end stage renal disease [ESRD]. As the patient had no vascular access for hemodialysis, the catheter was inserted in the right subclavian vein without an imaging guide. The woman experienced sudden chest pain and hypotension. Imaging showed a malposition of the catheter in the subclavian artery instead of the subclavian vein with dissection of the thoracic and abdominal aorta. This is a rare complication of subclavian vein catheterization for hemodialysis. We discuss this patient because she is the first in the international bibliography. This case report shows that for patients with poor venous access, catheter placement under angiographic control may be helpful
