Objective To discuss the way and management of cardiopulmonary bypass （CPB） through intubation of femoral artery and femoral vein for completely video assisted cardiac operations, Methods CPB were set up through femoral artery and femoral vein in 85 patients on heart surgery by video assisted thoracotomy. Thirtyeight patients were diagnosed as atrial septal defect （ASD）, forty-three patients were diagnosed as ventricular septal defect （VSD）, and four patients were mitral valve stenosis and mitral incompetence （MS＋MI）,The video assisted thoracotomy was used to repair ASD, VSD and mitral valve replacement （MVR）. Results For all patients the durations of CPB and aortic cross-clamping time was 30-179 min（91.7±27.4 min）, 6-103 min（37.2±6. 1 min）. In one patient, the CPB was set up again for repairing of residual leak. The endothelium of femoral artery was lacerated during withdrawing the cannula in 2 patients. Conclusion The video assisted thoracic operation with CPB and by intubation of femoral artery and femoral vein to perform heart operation are feasible and safe. All patients are recovered well.
Objective To systematically review the efficacy of eight time-restricted eating strategies on overweight/obese adults using network meta-analysis. MethodsThe Scopus, MEDLINE, Embase, PubMed, Web of Science, and Cochrane Library databases were electronically searched to collect studies on randomized controlled trials (RCTs) on the intervention effects of eight time-restricted eating strategies on overweight/obese adults from inception to September 18, 2024. Two researchers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Network meta-analysis was performed using ADDIS 1.16.8 and Stata 18.0 software. ResultsA total of 23 RCTs involving 1 306 overweight/obese adults were included. The network meta-analysis revealed that compared with standard diets, the 8-hour time-restricted eating combined with a low-carbohydrate diet (MD=−4.01, 95%CI −5.95 to −2.08, P<0.05) showed better weight reduction effects. Compared with standard diets, the 8-hour time-restricted eating combined with a low-carbohydrate diet (MD=−3.54, 95%CI −5.44 to −1.63, P<0.05) and the 8-hour time-restricted eating combined with a low-sugar diet (MD=−4.19, 95%CI −8.33 to −0.05, P<0.05) significantly improved overall fat mass. Compared with standard diets, the 8-hour time-restricted eating combined with a low-sugar diet (MD=−15.42, 95%CI −29.12 to −1.72, P<0.05) had a better effect on fasting blood glucose control. The 8-hour time-restricted eating combined with high-intensity interval training (MD=−3.68, 95%CI −6.57 to −0.79, P<0.05) showed better results in reducing waist circumference. No statistical significance was found in direct comparisons regarding bone mineral content. The efficacy ranking showed that the 8-hour time-restricted eating combined with a low-carbohydrate diet was most effective for weight reduction; the 8-hour time-restricted eating combined with a low-sugar diet was more effective in reducing overall fat mass and controlling fasting blood glucose; the 8-hour time-restricted eating combined with calorie restriction had significant effects on waist circumference improvement; and the 8-hour time-restricted eating combined with high-intensity interval training was more effective for increasing bone mineral content. ConclusionBased on the results of the network meta-analysis and ranking, different time-restricted eating strategies have specific advantages for the intervention of overweight or obese individuals. The choice of the appropriate strategy should consider individual dietary habits and health conditions. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
