Since the first report of coronary artery bypass grafting (CABG) in patients with end-stage renal disease in 1974, numerous reports have documented the feasibility of CABG in patients with chronic renal diseases. Patients with chronic renal failure often have comorbid disorders such as hypertension, and diabetes mellitus, each with their own complications and associated impact on both short and long-term survivals. In addition, infection and sepsis have been identified as significant causes of morbidity and mortality in most series of patients with end-stage renal disease undergoing cardiac surgical procedure. As a result of these and other factors such as perioperative volume and electrolyte disturbances, patients with chronic renal failures are at an increased risk of complication and mortality after CABG. We report 3 cases of "Off-pump" CABG in the chronic renal failure patients. patients.

Although re-expansion pulmonary edema (RPE) is rare (incidence rate <1%), it is associated with a mortality rate of >20%; therefore, early diagnosis and treatment are important. We report a case of RPE following chest tube insertion in a patient with spontaneous pneumothorax. We have specifically focused on the mechanism underlying RPE and the possible etiology. An 82-year-old man with a history of chronic anemia, chronic obstructive pulmonary disease, diabetes mellitus, and hypertension was referred to the emergency department for management of recurrent right-sided pneumothorax. We performed emergency closed thoracostomy for suspected tension pneumothorax, which led to stabilization of the patient's vital signs; however, he coughed up frothy pink sputum accompanied by severe right-sided chest pain 30 min postoperatively. The patient showed new-onset right pulmonary consolidation on chest radiography, as well as desaturation, tachycardia, and tachypnea and was diagnosed with RPE. He was transferred to the intensive care unit for mechanical ventilation and supportive treatment using diuretics, ionotropic agents, and prophylactic antibiotics. RPE gradually resolved, and the patient was extubated 3 days after admission. He has not experienced recurrent pneumothorax or pulmonary disease for 4 months. We emphasize the importance of RPE prevention and that aggressive ventilator care and supportive treatment can effectively treat RPE following an accurate understanding of the underlying pathogenetic mechanisms and risk factors.

Objective : Obesity is a disease caused by energy imbalance and increases the risk of complications such as cardiovascular disease and cancer. Additionally, a recent study reported that excessive production of ROS stimulates the expression of transcription factors related to adipogenesis, such as PPAR-𝛾, C/EBP-𝛼 and 𝛽, in 3T3-L1 cells. In this study, Paeonia anomala L. (PAL) was selected as a candidate for improving and preventing obesity from Mongolian medical literature, and its effect on fat metabolism was observed in vitro. Methods : The activity of PAL extract against lipid accumulation was measured in 3T3-L1 cells through Oil red O staining. Additionally, the expression of lipid metabolism-related proteins was measured by western blot. Results : Intracellular lipid accumulation was significantly lower in the treatment group than in the control group. In addition, pAMPK/AMPK protein expression in the treatment group tended to increase in a concentration-dependent manner, and PPAR-𝛾 protein expression in the treatment group showed a significant decrease in a concentration-dependent manner compared to the control group. Conclusion : These results suggest that PAL extract may have an anti-obesity effect, and it is believed that it can be used to develop functional materials for the treatment of obesity.

The purpose of this study was to analyze the effects of combined exercise on body composition and cardiovascular disease risk factors in sarcopenic obesity elderly women. The subjects for the study were 21 obesity elderly women over 65 years old . They were divided into two groups, the sarcopenic obesity group(n=9) and non-sarcopenic obesity group(n=12). The variables of body composition and cardiovascular fitness were measured in all the subjects before and after 16-week combined exercise. All data was analyzed by two-way ANOVA with repeated measures, and paired t-test by using SPSS 18.0. The findings of this study were as follows; 1. Effects on body composition The relationship between sarcopenia and body composition were only significant for the group ${\times}$ time interaction in FFM. In the sarcopenic obesity elderly women, % body fat significantly decreased and sarcopenia reduced by 30%, but there were no significant changes in the FFM and ASM. On the other hand, the non-sarcopenic obesity elderly women significantly decreased % body fat and significantly increased FFM and ASM. 2. Effects on cardiovascular fitness Both groups significantly increased V˙ O2peak. The most important finding in this study was that sarcopenic obesity elderly women showed delayed effects of a 16-week combined exercise on FFM and ASM compared to the non-sarcopenic obesity elderly women. However, the further studies might need to confirm these results with both genders, different age groups, and various exercise types.

Effective nutrition educations for prevention of chronic diseases for the general population are of great importance these days. The purpose of this study was to evaluate the feasibility of nutrition education for cardiovascular risk factor reduction by e-mail education in male workers. The participants were divided into three groups by age; 28-39 age group, 40-49 age group, and 50-59 age group who got regular checkups for anthropometry and biochemistry. The 1 year program consisted of 15 topics containing information about metabolic syndrome (MS) and healthy eating behavior (intake of salt, fat and alcohol). Seven hundred thirty nine participants volunteered for the study [28-39 age group, n = 240; body mass index (BMI) = 24.9 $\pm$ 2.7 kg/m$^2$: 40' group, n = 276; BMI = 24.8 $\pm$ 2.6 kg/m$^2$: 50' group, n = 223; BMI = 24.9 $\pm$ 2.7 kg/m$^2$]. Percentage body fat (p < 0.05) and percentage of abdominal fat (p < 0.05), total cholesterol (p < 0.05), systolic blood pressure (p < 0.05), and diastolic blood pressure (p < 0.05) were significantly decreased in all participants after the 1 year program. The total number of participants who had MS was decreased from 216 to 199 and especially the incidence of MS was decreased 27% in the group of subjects who were under the age 39. The e-mail worksite nutrition education program shows a substantial contribution to the development of effective CVD and chronic disease control and lifestyle nutrition educations that are applicable to and attractive for the large population at risk.

We reviewed our 18-year surgical experience of biventricular repair for double-outlet right ventricle. Material and Method: One hundred twelve consecutive patients (80 males and 32 females) who underwent biventricular repair for double-outlet right ventricle between May 1986 and September 2002 were included. We assessed risk factors for early mortality and reoperation. Reoperation-free survival rate and actual survival rate were analysed. Result: Most common type of ventricular septal defect was subaortic (n=58, 52%) and non-committed type was second most common (n=32, 29%). Four different surgical methods were used: intraventricular baffle repair (n=71 , 63%): right ventricle to pulmonary ariery conduit interposition or REV with left ventricle to aorta baffle repair (n=24, 21 .4%): arierial switch operation with left ventricle to pulmonary artery baffle (n=14, 12.5%): Senning atrial switch operation with left ventricle to pulmonary artery baffle (n=3, 2.7%). Thirty four patients(30%) underwent palliative procedures before definite repair. Twenty three patients (21%) required reoperations. There were 12 (10.7%) early deaths and 4 late deaths. Age younger than 3 months at repair (p=0.003), cardiopulmonary bypass and aortic cross clamp time (p=0.015, p=0.067), type of operation (arterial switch operation) (p <0.001) and type of ventricular septal defect (subpulmonic type) (p=0.002) were revealed as risk factors for early death in univariate analysis, while age under 3 months was the only significant risk factor in multivariate analysis. Patients younger than 1 year of age (p=0.02), pulmonary artery angioplasty at definitive repair (p=0.024), type of ventricular septal defect (non-committed) (p=0.001), type of operation (right ventricle to pulmonary artery conduit interposition and REV operation) (p=0.028, p=0.017) were risk factors for reoperation in univariate analysis but there was no significant risk factor in multivariate analysis. Follow-up was available on 91 survivals with a mean duration of 110.8$\pm$56.4 (2~201) months. 5, 10 and 15 year survival rates were 86.5%, 85% and 85% and reoperation free survival were 85%, 71.5%, 70%. Conclusion: Age under 3 months at repair, subpulmonic ventricular septal defect and arterial switch operation were significant risk factors for early mortality. Patients with non-committed ventricular septal defect and who underwent conduit interposition or REV operation were risk factors for reoperation. With careful attention to chose best timing and surgical approach depending on morphologic characteristics, biventricular repair for double outlet right ventricle can be achieved with good long-term outcome.

In an attempt to avoid the adverse effects of the cardiopulmonary bypass, off pump coronary artery bypass grafting(Off pump CABG) that has recently been rediscovered and refined. We compared the preoperative risk factors and in-hospital outcomes of patients done Off pump with those done On pump CABG. Material na Method: One hundred seventy eight patients was underwent CABG between January 2001 and July 2001 12 patients whom underwent associated valvular or left ventricular volume reduction surgery were excluded in this study Data were collected for 52 Off pump CABG and 114 On pump CABG for patient and disease risk factors, extent of coronary disease, and in-hospital outcomes. Result: Off pump CABG and On pump CABG groups did not show any differences in their patient and disease risk factors, and extent of coronary disease. Off pump CABG group had significantly lower mean operation time(234 $\pm$ 37 min vs 290 $\pm$ 48 min, p<0.001), lower mean CK-MB level(10.1 $\pm$ 13.5 IU/L vs 33.1 $\pm$ 18.2 IU/L, p<0.001) and mean ventilation time(14.8 $\pm$ 3.5 hours vs 16.2 $\pm$ 4.9 hours, p=0.048) than On pump CABG groups. On pump CABG group had significantly more distal grafts(3.4 $\pm$ 0.9 vs 2.6 $\pm$ 0.8, p<0.001) than Off pump CABG groups. There were no operative mortality in two groups. Off pump) CABG and On pump CABG groups did not show any differences in their postoperative complications and outcomes including perioperative myocardial infarction, stroke, respiratory failure, renal failure, reoperation, the amount of bleeding, the need of intraaortic balloon pump, the need of inotropics, and the stay of intensive care unit and hospital. Two patients were converted to On pump CABG. Conclusion: This study showed that patients having Off pump CABG are not exposed to a greater risks of adverse outcomes and also provided evidence that patients having Off pump CABG have significantly lower operation time, CK-MB, ventilation time and less distal grafts. Although there may be potential benefits to Off pump CABG, further studies must be directed to determine those patients who would benefit from Off pump CABG.

Background: In the majority of cases, sternal instability and wound infection concomitantly present after a cardiac operation following conventional median sternotomy, and these complications have a major influence on the postoperative course. The aim of this study is to compare the results of the different sternal wiring techniques of sternal infection. Material and Method: Between April 2004 and December 2008, 157 adult patients underwent cardiac in group A, whereas 71 patients who had undergone modified Robicsek sternal wiring were included in group B. The incidences of sternal wound complications in the two groups were assessed. Result: The mean age of the group B patients was older than that of the group A patients ($61{\pm}10$ years vs $57{\pm}13$ years). The incidence of preoperative left ventricular dysfunction (ejection fraction <30%), chronic obstructive pulmonary disease, renal failure requiring dialysis and diabetes mellitus were significantly higher in Group B, whereas the other perioperative risk factors for infection were not significantly different between the two groups. Two patients in group A experienced superficial wound infection, whereas 4 patients in group B displayed superficial wound infection, but the difference was not statistically significant (p=0.255). Yet poststernotomy deep sternal wound infection appeared in 6 patients of group A, whereas none of the patients in group B displayed this malady. Conclusion: The modified Robicsek sternal wiring technique showed greater sternal stability even for the patient with a high risk for infection, and the technique caused a lower incidence of deep sternal wound infection.

Background: A previous percutaneous coronary intervention (PCI) may affect the outcomes of patients who undergo coronary artery bypass grafting (CABG). The objective of this study was to compare the early in-hospital postoperative outcomes between patients who underwent CABG with or without previous PCI. Methods: The present study included 160 patients who underwent isolated elective on-pump CABG at the department of cardiothoracic surgery, Minia University Hospital from January 2010 to December 2014. Patients who previously underwent PCI (n=38) were compared to patients who did not (n=122). Preoperative, operative, and early in-hospital postoperative data were analyzed. The end points of the study were in-hospital mortality and postoperative major adverse events. Results: Non-significant differences were found between the study groups regarding preoperative demographic data, risk factors, left ventricular ejection fraction, New York Heart Association class, EuroSCORE, the presence of left main disease, reoperation for bleeding, postoperative acute myocardial infarction, a neurological deficit, need for renal dialysis, hospital stay, and in-hospital mortality. The average time from PCI to CABG was $13.9{\pm}5.4$ years. The previous PCI group exhibited a significantly larger proportion of patients who experienced in-hospital major adverse events (15.8% vs. 2.5%, p=0.002). On multivariate analysis, only previous PCI was found to be a significant predictor of major adverse events (odds ratio, 0.16; 95% confidence interval, 0.03 to 0.71; p=0.01). Conclusion: Previous PCI was found to have a significant effect on the incidence of early major adverse events after CABG. Further large-scale and long-term studies are recommended.

Background: Smoking is known as a major risk factor for different types of cancer, as well as cardiovascular disease. Its prevalence is increasing in developing countries. The aims of this study were to determine the prevalence of smoking and its associated factors among the population aged 40-64 years in the city of Shahroud which is a representative urban population in Iran. Materials and Methods: A cross-sectional population-based study with stratified random cluster sampling was conducted in 2009 as the first phase of Shahroud Eye Cohort Study. Of 6,311 people, 5,190 participated (82.2%). Information about smoking habit was obtained by face-to-face interview. Results: The overall prevalence of current tobacco smoking was 11.3% (95%CI: 10.5-12.3). It was significantly higher among males than females (25.7% and 0.71%, P<0.001). The prevalence of current cigarette smoking was 10.8% and 1.75% were past smokers. The smoking rate of water-pipe was 0.67%. Unemployed people smoked more than employed (OR=2.66, 95%CI: 1.38-5.14). Conclusions: The prevalence of smoking is low in Shahroud compared with other parts of Iran and other countries. Age, sex, job and marital status were associated with smoking. The low smoking rate among women may be attributed to cultural and social reasons.
