Objective To investigate the effect of dapagliflozin on myocardial work and energy metabolism in patients with heart failure with reduced ejection fraction(HFrEF)without type 2 diabetes mellitus(T2DM).Methods Patients with HFrEF without T2DM who visited Wuzhou People's Hospital from January 2021 to January 2022 were randomly divided into conventional group and dapagliflozin group(conventional treatment+dapagliflozin).After treatment(12 months),myocardial work[global work index(GWI),global constructed work(GCW),global wasted work(GW),and global work efficiency(GWE)],energy metabolism[(free fatty acids(FFA)and β-hydroxybutyric acid(β-HB)],traditional cardiac function[left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),and left ventricular ejection fraction(LVEF)],clinical efficacy,prognosis[mortality,rehospitalization,and incidence of major adverse cardiovascular events(MACE)]and adverse reactions were compared between the two groups.Results A total of 128 patients with HFrEF without T2DM were enrolled,including 63 patients in the dapagliflozin group and 65 patients in the conventional group.After treatment,the LVEDD,LVESD,GWW,NT-pro BNP in the dapagliflozin group was significantly lower than that in the conventional group(P＜0.05),while the LVEF,GWI,GCW,GWE,β-HB acid and FFA were significantly higher than those in the conventional group(P＜0.05).The total effective rate and hypoglycemia rates in the dapagliflozin group were significantly higher than those in the conventional group(P＜0.05),and the rehospitalization rate and MACE rate were significantly lower than those in the conventional group(P＜0.05).There were no significant differences in mortality,renal adverse events,urinary tract infections and gastrointestinal symptoms between the two groups(P＞0.05).Conclusion Dapagliflozin has significant clinical efficacy in patients with HFrEF without T2DM,which can increase the serum levels of FFA and ketones,improve effective work,and reduce ineffective work,but it is necessary to be vigilant against hypoglycemia.
Résumé
Objective To evaluate the safety and therapeutic effects of stent retriever-based thrombectomy (SRT) on acute ischemic stroke (AIS) in patients aged 80 years and older.Methods A cohort of 157 AIS patients hospitalized in Capital Medical University Affiliated Beijing Tiantan Hospital were selected for SRT from January 2016 to May 2017.Based on the age,all patients were divided into two groups:groups aged ＜ 80 years and ≥ 80 years.Baseline information including gender,the Modified Rankin Scale (mRS) score,past medical history,smoking history,preoperative National Institutes of Health Stroke Scale (NIHSS),the Alberta Stroke Program Early CT Scores (ASPECTS),intravenous thrombolysis and clinical outcomes were compared between two groups.The informations related to the operation,including time from onset to hospital,door-to-needle puncture time,door-to-recanalization time,SRT complications (symptomatic cerebral hemorrhage,mortality) and good outcome,were compared between two groups.Logistic regression analysis was used to determine whether the age of 80 years and over was a risk factor for adverse prognosis after SRT.Results There were 130 patients in the group ＜ 80 years of age,and 27 patients in the group ≥80 years.No significant differences were found in baseline information between the two groups (all P＞ 0.05).In addition,there were no significant differences in the proportions of the operative information,complications of SRT and the good outcome (all P＞0.05).Furthermore,advanced age (≥80 years) was not a risk factor for adverse outcome after SRT (OR =0.738,95％ CI:0.300-1.813).Conclusions Stent retriever-based thrombectomy is safe and beneficial for patients with acute ischemic stroke,even in patients aged 80 years and over.
Résumé
Objective To discuss the optimal retrieval time of the indwelling Gunther Tulip and Cook Celcet inferior vena cava filters (VCF). Methods During the period from March 2013 to April 2015 at Shengli Oilfield Central Hospital, the implantation of retrievable inferior vena cava filter was performed in 58 patients. Among the 58 patients, Gunther Tulip VCF was used in 13 and Cook Celcet VCF was employed in 31. Twenty-one patients followed the doctor's advice to receive retrieval procedure of VCF within three months after the implantation. Results Among the 21 patients, successful retrieval of VCF was obtained in 19. The mean indwelling time of Gunther Tulip VCF was 54.4 days, the longest time being 79.0 days. Gunther Tulip VCF was successfully removed in 3 patients and retrieval of VCF failed in 2 patients, with a retrieval success rate of 60%. The mean indwelling time of Cook Celcet VCF was 37.6 days, the longest time being 67.0 days. Cook Celcet VCF was successfully removed in 16 patients, with the success rate of retrieval being 100%. Conclusion Despite many VCFs that have been indwelled for a long time can be safely retrieved, retrieval procedure should be performed as early as possible in order to improve the retrieval success rate of VCF. It seems that the use of Cook Celcet VCF is a better choice although it is more expensive.
