Abstract

Background: Cholangiocarcinoma is a cancer of the bile duct epithelium that originates from the bile ducts inside or outside the liver. Although this tumor is not common, its mortality rate is high. This tumor accounts for about 3% of all gastrointestinal malignancies. Many patients are being detected when the disease has spread. Evaluating risk factors affecting the incidence of cholangiocarcinoma is very important to avoid exposure to them. Therefore, this study was performed to evaluate the risk factors for cholangiocarcinoma in a population in Iran.
Methods: This was a descriptive cross-sectional study. It was performed on 276 patients with cholangiocarcinoma who had been referred to Firoozgar Hospital affiliated with the Iran University of Medical Sciences in Tehran from March 2020 to February 2021. Demographic information, family and personal history, social history (tobacco or drug use) and blood group of patients were extracted from their files. SPSS version 16 was used for data analysis. A P-value below 0.05 was considered statistically significant.
Results: The mean±SD age of patients was 65.97±13.07 years, of whom 65.6% were male and 34.4% were females. The most common site of cholangiocarcinoma was the distal part of the bile ducts and the most common blood group was O+. The main manifestations were jaundice and pruritus. Among the risk factors, the most common ones were smoking, high blood pressure, history of gallstones, opium use, history of cancer of other systems in the family, history of cholecystectomy and diabetes mellitus. While, the lowest prevalence of risk factors was related to heroin use, IBD, Gallbladder polyps, pancreatitis and alcohol consumption. None of the patients in our study had a history of viral hepatitis or PSC.
Conclusion: This was a cross-sectional study and only in the group of cholangiocarcinoma patients, therefore, larger prospective studies are recommended to examine underlying mechanisms of malignant transformation in the biliary tree.

Abstract

Background: smoking enhances the risk of cardiac events in patients with coronary artery disease. So, it is necessary to evaluate the effects of exercise-based cardiac rehabilitation on endothelial function and functional capacity among smoker patients.
Methods: This randomized clinical trial study was conducted on 56 non-diabetic smokers with a history of percutaneous coronary intervention or coronary artery bypass graft surgery in Imam Khomeini Hospital from May to August 2015. Based on cardiac rehabilitation, patients were divided into intervention and control groups. Before rehabilitation, fasting blood sugar (FBS), lipid profile (LDL, HDL, triglyceride, and total cholesterol), and Ankle-Brachial Index (ABI) were measured for endothelial function. Besides, METs were measured based on the Duke activity status index. After 24 rehabilitation sessions (3 sessions of 1 hour each week for 2 months), all values were checked again and compared with the initial values.
Results: The mean age of the subjects in the cardiac rehabilitation and control groups were 61.18 and 52.32, respectively. Before the intervention, there were no significant differences between the two groups in terms of the ABI variables, BMI, systolic and diastolic blood pressure, LDL, triglyceride, total cholesterol and FBS; only HDL and  METs showed significant differences. After exercise-based cardiac rehabilitation, the mean rate of ABI changes was +0.078 on the right side of the body and +0.084 on the left side of the body. In the control group, these values were 0.002 and 0.003, respectively (P=0.001). The amount of changes in increasing METs as well as decreasing body mass index (BMI), and systolic and diastolic blood pressure in the rehabilitation group were statistically significant compared to the control group. In addition, there were no significant differences in terms of FBS and lipid profiles either (P>0.05).
Conclusion: Two months of cardiac rehabilitation with regular exercise was associated with improved ABI as an indicator of endothelial function and prognosis of cardiovascular disease, as well as improved cardiac functional capacity among smoker patients.
