Successful Use of Surgically Placed Impella 5.0 and Central Extracorporeal Membrane Oxygenation Circuit in a Patient with Postcardiotomy Shock

The Impella 5.0, a percutaneously inserted left ventricular assist device, has been used to support patients who have severe heart failure or who are undergoing high-risk percutaneous coronary intervention. We report our surgical placement of the Impella 5.0, through a graft sewn to the aorta, to unload the left ventricle of a 59-year-old man who was undergoing venoarterial extracorporeal membrane oxygenation for postcardiotomy shock. The patient underwent successful placement of a long-term left ventricular assist device before his discharge from the hospital. The versatility of the Impella 5.0 is exemplified in this patient who was successfully bridged to long-term support.     

Predictive value of HbA1c for in-hospital adverse prognosis in COVID-19: A systematic review and meta-analysis

Background and aimsClinical and laboratory predictors of adverse clinical course and death in COVID-19 patients urgently need to be identified. So far, the association between HbA1c and in-hospital mortality of COVID-19 remains a controversial issue. The aim of this study is to analyze predictive value of HbA1c for adverse prognosis in COVID-19.MethodsBoth Chinese and English databases were systematically searched using specific keywords associated with the aims until November 21th, 2020. The Newcastle-Ottawa Scale (NOS) was used for quality assessment. A Statistical analysis was carried out using Review Manager 5.3 and STATA 15.1.ResultsNine clinical trials were included in this study involving 2577 subjects. The results indicate that the association between elevated HbA1c referred as a continuous variable and adverse prognosis of COVID-19 was not significant (OR, 1.02; 95%CI, 0.95–1.09). However, higher HbA1c levels regarded as a dichotomous variable contributed to an increase mortality of COVID-19 (OR, 2.300; 95%CI, 1.679–3.150). Results were stable in a sensitivity analysis. More studies are needed to demonstrate the effect of HbA1c on hospital mortality.ConclusionProlonged uncontrolled hyperglycemia increases the risk of adverse prognosis in COVID-19. Patients with higher HbA1c should be monitored strictly to minimize the risk of adverse prognosis in COVID-19.     

User experiences with second-generation 32-gauge × 4 mm vs. thinner comparator pen needles: prospective randomized trial

糖尿病患者腹部手术围手术期的处理

糖尿病已成为全球威胁人类健康的三大慢性非传染性疾病之一。需要外科手术的患者占所有糖尿病患者的25%,其围手术期病死率、并发症以及住院时间较正常人明显增加,因此对于糖尿病患者围手术期的处理方案显得尤为重要。但目前对于围手术期血糖控制范围仍众说纷纭,综合各研究结论,笔者认为将血糖控制在7.8~10 mmol/L是一个较为理想的范围。在患者术前、术中及术后应联合多学科制定各项相应的治疗方案,围手术期尤为注意避免患者发生低血糖和电解质紊乱的发生。也亟待后续大规模的随机对照试验进一步确定有效的血糖控制目标。     

“Diabetes care at doorsteps”: A customised mobile van for the prevention,screening, detection and management of diabetes in the urban underprivileged populations of Delhi

Diabetes is on the rise in India and recently shown to be increasing in the urban underprivileged. Lack of awareness of the disease, its complications, combined with lack of financial resources among the underprivileged, often results in late detection and more complications in them. To combat this, healthcare delivered at the doorstep through the use of a customised mobile medical van is a potentially attractive option.We used a customized mobile van (included trained personnel, glucose meters, fundus evaluation camera, apparatus for detection of neuropathy and foot circulation and net enabled Skype calling for remote consultation) for educating general population regarding healthy lifestyle and screening, management and intervention in patients with diabetes.The project covered 10 underprivileged areas (n, 2,31,000 people) in Delhi. Total of 24,072 individuals (10.9% of total population) attended 352 awareness sessions. A total 3,12,347 visits (included repeat visits) were carried out for screening, education and management for obesity and diabetes. During screening (n, 16,834), 2933 subjects (18.7%) had high random blood glucose levels (>200 mg/dL) and had a blood pressure averaging 127.1 ± 23.6/81.3 ± 16.6 mm of mercury (n, 16,339). A pre-post intensive lifestyle counselling for 6 months in a subset of 352 diabetic patients (of which 77.8% i.e. n, 274 were overweight/obese) showed a significant lowering in weight (p < 0.001). In addition, 292 frontline workers and 256 paramedical workers were given training regarding lifestyle and diabetes, over 20 sessions.Based on achievements of this project of spreading awareness, screening, and management of diabetes and obesity in the large number of individuals in urban underprivileged colony, we believe this project could be extended to other cities and rural areas of India, and to other developing countries as well.
