Preoperative HbA1c levels might not predict long-term outcomes for diabetic patients undergoing OPCAB. Careful evaluation for diabetes should be needed in preoperative management of CABG.
ObjectivesTo determine whether febuxostat with stepwise dose increase is as useful as colchicine prophylaxis in reducing gout flares during the initial introduction of urate-lowering therapy in patients with gout in comparison with febuxostat with no dose titration.MethodsIn this prospective, multicentre, randomised open-label comparative study, patients were randomised to group A (stepwise dose increase of febuxostat from 10 to 40 mg/day), group B (fixed-dose febuxostat 40 mg/day plus colchicine 0.5 mg/day) or group C (fixed-dose febuxostat 40 mg/day) and observed for 12 weeks. Gout flare was defined as non-steroidal anti-inflammatory drug use for gout symptoms.ResultsA total of 255 patients were randomised, and 241 patients were treated. Among the treated patients, gout flares were experienced by 20/96 (20.8%) in group A, 18/95 (18.9%) in group B and 18/50 (36.0%) in group C. The incidence of flare was significantly lower in groups A and B than that in group C (P=0.047 and P=0.024, respectively), although the differences were not significant after correction for multiple comparisons. No significant difference was noted between the incidence of gout flare in groups A and B.ConclusionsOur data suggested that stepwise dose increase of febuxostat and low-dose colchicine prophylaxis effectively reduced gout flares in comparison with fixed-dose febuxostat alone. Stepwise dose increase of febuxostat may be an effective alternative to low-dose colchicine prophylaxis during the introduction of urate-lowering therapy.Trial registration numberUMIN 000008414.
Reports on the incidence of persistent left superior vena cava (PLSVC) in the normal population are limited to studies involving pacemaker implantation candidates and cadavers. The incidence in patients with congenital heart diseases (CHDs) is estimated to be higher than that in the normal population; however, the details are unclear. To investigate the incidence of PLSVC in the normal population and in patients with CHDs, subjects were examined prospectively using echocardiography. Normal subjects consisted of 2841 successive neonates without intra-cardiac or congenital anomalies born in Gifu Prefectural General Medical Center. Additionally, 1920 patients with CHDs were evaluated. The incidence of PLSVC in normal neonates was 0.21% (95% confidence interval 0.042-0.38%). A high incidence (more than 7.0 times the incidence in normal subjects) was observed in all CHD patients. The high incidence group included coarctation of the aorta (CoA) (23.7%) and double outlet right ventricle (DORV) patients (24.6%). The second group consisted of CHD patients with ventricular septal defect (VSD), with an incidence ranging from 5.1 to 6.1%. The low incidence group comprised patients with other CHDs, with an incidence between 1.5 and 3.1%. The incidence of PLSVC in trisomy 21 and atrial septal defect patients was significantly higher than that in normal neonates. The incidence of PLSVC in the normal population and in patients with CHDs was systematically evaluated for the first time. The incidence in CHD patients appeared to be positively influenced by the type of CHD, particularly by DORV, CoA, and VSD.
These data suggest that improvement in muscle strength may be influenced by changes in muscle mass and high glucose levels in DM patients undergoing CR after CABG. A CR program, including muscle mass intervention and blood glucose control, may improve deterioration in exercise tolerance in DM patients after CABG.
Background: The impact of diabetes mellitus (DM) on muscle mass, muscle strength, and exercise tolerance in patients who had undergone coronary artery bypass grafting (CABG) has not been fully elucidated. Methods: We enrolled 329 consecutive patients who received cardiac rehabilitation (CR) after CABG (DM group, n = 178; non-DM group, n = 151) and measured lean body weight, mid-upper arm muscle area (MAMA), and handgrip power (HGP) at the beginning of CR. We also performed an isokinetic strength test of the knee extensor (Ext) and flexor (Flex) muscles and a cardiopulmonary exercise testing at the same time. Results: No significant differences in risk factors, including age, gender, number of diseased vessels, or ejection fraction were observed between the 2 groups. The levels of Ext muscle strength, peak oxygen uptake, and anaerobic threshold were significantly lower in the DM group than in the non-DM group (all p < 0.05). Both peak oxygen uptake and MAMA correlated with Ext and Flex muscle strength as well as HGP (all p < 0.005). The MAMA, HGP, and Ext muscle strength were lower in patients who received insulin therapy than in those who did not. Interestingly, fasting glucose levels significantly and negatively correlated with Ext muscle strength.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
