Abstract
AIMS To investigate the clinical characteristics, laboratory findings and high- resolution CT (HRCT) features and to explore the risk factors for in-hospital death and complications of coronavirus disease 2019 (COVID-19) patients with diabetes. METHODS From Dec 31, 2019, to Apr 5, 2020, a total of 132 laboratory-confirmed COVID-19 patients with diabetes from two hospitals were retrospectively included in our study. Clinical, laboratory and chest CT data were analyzed and compared between the two groups with an admission glucose level of ≤11 mmol/L (group 1) and >11 mmol/L (group 2). Logistic regression analyses were used to identify the risk factors associated with in-hospital death and complications. RESULTS Of 132 patients, 15 died in hospital and 113 were discharged. Patients in group 2 were more likely to require intensive care unit care (21.4% vs. 9.2%), to develop acute respiratory distress syndrome (ARDS) (23.2% vs. 9.2%) and acute cardiac injury (12.5% vs. 1.3%), and had a higher death rate (19.6% vs. 5.3%) than group 1. In the multivariable analysis, patients with admission glucose of >11 mmol/l had an increased risk of death (OR: 7.629, 95%CI: 1.391-37.984) and in-hospital complications (OR: 3.232, 95%CI: 1.393-7.498). Admission d-dimer of ≥1.5 μg/mL (OR: 6.645, 95%CI: 1.212-36.444) and HRCT score of ≥10 (OR: 7.792, 95%CI: 2.195-28.958) were associated with increased odds of in-hospital death and complications, respectively. CONCLUSIONS In COVID-19 patients with diabetes, poorly-controlled blood glucose (>11 mmol/L) may be associated with poor outcomes. Admission hyperglycemia, elevated d-dimer and high HRCT score are potential risk factors for adverse outcomes and death.

Abstract
BACKGROUND It is controversial whether tighter glycemic control is associated with better clinical outcomes in people with kidney failure. We aim to determine whether worse glycemic control, measured using serum glucose and hemoglobin A(1c) (HbA(1c)) levels, is independently associated with higher mortality in patients undergoing maintenance hemodialysis. STUDY DESIGN Retrospective cohort study. SETTING & PARTICIPANTS 1,484 patients starting maintenance hemodialysis therapy in Alberta, Canada, between 2001 and 2007. PREDICTOR Serum glucose and HbA(1c) levels. OUTCOME All-cause mortality. MEASUREMENTS Monthly casual glucose levels from specimens drawn immediately before the first dialysis treatment were averaged over 3 months before and after hemodialysis therapy initiation. Similarly, monthly HbA(1c) values in patients with or at risk of diabetes were averaged. RESULTS Overall, median age was 66 years, 41% were women, 75% were white, and 55% had diabetes. All-cause mortality during 8 years (median, 1.5 years) was 43%; it was 49% in those with diabetes. There was no relation between average glucose level and mortality in unadjusted analysis (HR, 1.00 per 18 mg/dL [1 mmol/L]; P = 0.4) or after adjustment for confounders (HR, 0.98 per 18 mg/dL; 95% CI, 0.96-1.01; P = 0.2). Higher HbA(1c) level was not associated with mortality when analyzed in the unadjusted analysis (HR, 1.01 per 1% HbA(1c); P = 0.9) or after adjustment for confounders (HR, 0.98 per 1% HbA1c; 95% CI, 0.88-1.08; P = 0.7). Results were similar when HbA(1c) values were divided into prespecified categories (adjusted P > 0.6 for trend). Markers of malnutrition-inflammation (albumin, hemoglobin, and white blood cell values) or the presence of diabetes did not influence the relation between glycemic control and death (all P for interaction > 0.2). LIMITATIONS Registry data; casual serum glucose measurements; HbA(1c) values available for only a subset of participants. CONCLUSIONS Higher casual glucose and HbA(1c) levels were not associated with mortality in maintenance hemodialysis patients with or without diabetes. This may have implications for recommended glycemic targets, quality indicators, and how best to assess glycemic control in this high-risk population.

Abstract
OBJECTIVE To examine whether hyperglycemia at the time of presentation was associated with outcomes in patients admitted to non-intensive care settings with community-acquired pneumonia (CAP). RESEARCH DESIGN AND METHODS Prospective cohort study of consecutive patients admitted to six hospitals between 15 November 2000 and 14 November 2002. RESULTS Of the 2,471 patients in this study (median age 75 years), 279 (11%) had serum glucose at presentation >11 mmol/l: 178 of the 401 patients (44%) with a prior diagnosis of diabetes and 101 of the 2,070 patients (5%) without a history of diabetes. Of patients hospitalized with CAP, 9% died and 23% suffered an in-hospital complication. Compared with those with values < or =11 mmol/l, patients with an admission glucose >11 mmol/l had an increased risk of death (13 vs. 9%, P = 0.03) and in-hospital complications (29 vs. 22%, P = 0.01). Compared with those patients with admission glucose < or =6.1 mmol/l, the mortality risk was 73% higher (95% CI 12-168%) and the in-hospital complication risk was 52% higher (12-108%) in patients with admission glucose >11 mmol/l. Even after adjustment for factors in the Pneumonia Severity Index, hyperglycemia on admission remained significantly associated with subsequent adverse outcomes: for each 1-mmol/l increase, risk of in-hospital complications increased 3% (0.2-6%). CONCLUSIONS Hyperglycemia on admission is independently associated with adverse outcomes in patients with CAP, with the increased risks evident at lower glucose levels than previously reported.

Abstract
OBJECTIVE: To evaluate the clinical outcomes of glycemic control of intensive insulin therapy and recommend its place in the management of critically ill patients. DATA SOURCES: Searches of MEDLINE (1966—March 2004) and Cochrane Library, as well as an extensive manual review of abstracts were performed using the key search terms hyperglycemia, insulin, intensive care unit, critically ill, outcomes, and guidelines and algorithms. STUDY SELECTION AND DATA EXTRACTION: All articles identified from the data sources were evaluated and deemed relevant if they included and assessed clinical outcomes. DATA SYNTHESIS: Mortality among patients with prolonged critical illness exceeds 20%, and most deaths are attributable to sepsis and multisystem organ failure. Hyperglycemia is common in critically ill patients, even in those with no history of diabetes mellitus. Maintaining normoglycemia with insulin in critically ill patients has been shown to improve neurologic, cardiovascular, and infectious outcomes. Most importantly, morbidity and mortality are reduced with aggressive insulin therapy. This information can be implemented into protocols to maintain strict control of glucose. CONCLUSIONS: Use of insulin protocols in critically ill patients improves blood glucose control and reduces morbidity and mortality in critically ill populations. Glucose levels in critically ill patients should be controlled through implementation of insulin protocols with the goal to achieve normoglycemia, regardless of a history of diabetes. Frequent monitoring is imperative to avoid hypoglycemia.

Abstract
OBJECTIVE There are conflicting results regarding the impact of type 2 diabetes on intravenous thrombolysis effectiveness during ST elevation myocardial infarction (STEMI). The present study, using a continuous 12-lead electrocardiogram, examined the possible association of type 2 diabetes with both acute intravenous thrombolysis effectiveness and long-term prognosis in this setting. RESEARCH DESIGN AND METHODS The study included 726 consecutive subjects (214 type 2 diabetic subjects) with STEMI who received intravenous thrombolysis in the first 6 h from index pain and were followed up for 3.5 years. RESULTS Type 2 diabetic subjects had significantly lower incidence of sustained > or = 50% ST recovery than nondiabetic subjects (P = 0.03). Additionally, the former required a significantly greater time interval through the achievement of this criterion than the latter (P < 0.001). In both type 2 diabetic (P < 0.001) and nondiabetic subjects (P < 0.001), those who had not attained > or = 50% ST recovery were at significantly higher risk of cardiac death than subjects who had reached this criterion. The subjects who attained the above electrocardiographic criterion in > or = 60 min after thrombolysis initiation were at significantly higher risk compared with those who achieved this criterion in <60 min (P = 0.02). However, this association was true only for type 2 diabetic subjects (P = 0.01) and not for nondiabetic subjects (P = 0.9). CONCLUSIONS The present study suggests that type 2 diabetes is a strong predictor of acute intravenous thrombolysis failure during STEMI. This finding may significantly contribute to the worse prognosis for type 2 diabetic subjects compared with nondiabetic ones in this setting.

Abstract
OBJECTIVE To determine the adequacy of perioperative glycemic control in diabetic patients undergoing coronary artery bypass grafting (CABG) and to explore the association between glycemic control and in-hospital morbidity/mortality. RESEARCH DESIGN AND METHODS Retrospective cohort study of consecutive patients with diabetes undergoing CABG between April 2000 and March 2001 who survived at least 24 h postoperatively. RESULTS Of the 291 patients in this study, 95% had type 2 diabetes and 40% had retinopathy, nephropathy, or neuropathy at baseline. During hospitalization (median 7 days), 78 (27%) of these patients suffered a nonfatal stroke or myocardial infarction, septic complication, or died ("adverse outcomes"). Glycemic control was suboptimal (average glucose on first postoperative day was 11.4 [11.2-11.6] mmol/l) and was significantly associated with adverse outcomes post-CABG (P = 0.03). Patients whose average glucose level was in the highest quartile on postoperative day 1 had higher risk of adverse outcomes after the first postoperative day than those with glucose in the lowest quartile (odds ratio 2.5 [1.1-5.3]). Even after adjustment for other clinical and operative factors, average blood glucose level on the first postoperative day remained significantly associated with subsequent adverse outcomes: for each 1-mmol/l increase above 6.1 mmol/l, risk increased by 17%. CONCLUSIONS Perioperative glycemic control in our cohort of diabetic patients undergoing CABG in a tertiary care facility was suboptimal. We believe closure of this care gap is imperative, because hyperglycemia in the first postoperative day was associated with subsequent adverse outcomes in our study patients.

The role of strict metabolic control by insulin infusion on fibrinolytic profile during an acute coronary event in diabetic patients. Clin Cardiol 2000; 23:160-4.

Abstract
BACKGROUND Many clinical and laboratory observations give support to the hypothesis that strict metabolic control by insulin infusion during acute coronary events may improve the ischemic damage and prognosis. HYPOTHESIS We investigated the impact of intensive insulin treatment on fibrinolytic parameters during an acute ischemic myocardial event (unstable angina or acute myocardial infarction) in patients with type 2 diabetes mellitus. METHODS The study group consisted of 48 type 2 diabetic patients, of whom 24 were randomized to conventional therapy plus intensive insulin treatment (Group 1) and 24 to conventional therapy only (Group 2). The two groups were comparable according to gender, age, body mass index, waist:hip ratio, duration of diabetes, previous antidiabetic treatment, type of ischemic events, concomitant therapy, and the classic risk factors for coronary disease. Insulin-treated patients were excluded from the study. Plasma levels of fibrinogen, tissue plasminogen activator (t-PA), and plasminogen activator inhibitor-1 (PAI-1) were measured on admission and discharge. Fibrinogen (fibr) was measured using the photometric method. PAI-1 and t-PA were measured by enzyme-linked immunosorbent assays. RESULTS T-PA increased in both groups during hospitalization (t-PA(admission) vs. t-PA(discharge): Group 1: 15.42 +/- 4.4 ng x ml(-1) vs. 21.2 +/- 5.74 ng x ml(-1), p = 0.000037; Group 2: 14.47 +/- 6.31 ng x ml(-1) vs. 19.18 +/- 6.88 ng x ml(-1), p = 0.001). On the other hand, fibr and PAI-1 levels increased remarkably in controls (Group 2, fibr(admission) vs. fibr(discharge): 2.98 +/- 1.04 g x l(-1) vs. 3.59 +/- 1.01 g x l(-1), p = 0.002, and PAI-1admission vs. PAI-1 discharge: 30.6 +/- 17.34 ng x ml(-1) vs. 40.62 +/- 23.48 ng x ml(-1), p = 0.003). This finding was not observed in the intensive insulin treatment group (Group 1, fibr(admission) vs. fibr(discharge): 2.87 +/- 0.73 g x l(-1) vs. 2.67 +/- 0.72 g x l(-1), p = 0.101, and PAI-1 admission vs. PAI-1 discharge: 30.75 +/- 15.81 ng x ml(-1) vs. 27.75 +/- 6.43 ng x ml(-1), p = 0.484). CONCLUSION Intensive insulin treatment during an acute coronary event improves fibrinolytic profile in patients with diabetes mellitus. This is a possible mechanism for the reduced short- and long-term mortality in diabetic patients treated with intensive insulin treatment protocol.

Abstract
The effect of chronic stress on tissue-type plasminogen activator (TPA) and plasminogen activator inhibitor-1 (PAI-1) antigens was studied in 69 healthy middle-aged men. Chronic stress, defined as feelings of fatigue, lack of energy, increased irritability, and demoralization, was positively associated with plasma concentrations of PAI-1 antigen but was unrelated to TPA. The association remained unaltered after controlling for age, smoking, alcohol consumption, and physical activity but became nonsignificant after further controlling for abdominal obesity, BMI, and serum insulin and triglyceride levels. This attenuated association implies that the relationship between vital exhaustion and PAI-1 may be secondary to the effects of the metabolic variables. Thus, the present study shows that long-term stress affects the fibrinolytic system and suggests that obesity and insulin and triglyceride concentrations, which are closely correlated with the fibrinolytic parameters, may mediate the association. These findings are consistent with the hypothesis that chronic stress causes increased synthesis of PAI-1, thus promoting the risk for atherothrombotic disease by decreasing the likelihood of spontaneous fibrinolysis and increasing the likelihood of fibrin deposition.

Abstract
OBJECTIVES We tested how insulin-glucose infusion followed by multidose insulin treatment in diabetic patients with acute myocardial infarction affected mortality during the subsequent 12 months of follow-up. BACKGROUND Despite significant improvements in acute coronary care, diabetic patients with acute myocardial infarction still have a high mortality rate. METHODS A total of 620 patients were studied: 306 randomized to treatment with insulin-glucose infusion followed by multidose subcutaneous insulin for > or = 3 months and 314 to conventional therapy. RESULTS The two groups were well matched for baseline characteristics. Blood glucose decreased from 15.4 +/- 4.1 to 9.6 +/- 3.3 mmol/liter (mean +/- SD) in the infusion group during the 1st 24 h, and from 15.7 +/- 4.2 to 11.7 +/- 4.1 among control patients (p < 0.0001). After 1 year 57 subjects (18.6%) in the infusion group and 82 (26.1%) in the control group had died (relative mortality reduction 29%, p = 0.027). The mortality reduction was particularly evident in patients who had a low cardiovascular risk profile and no previous insulin treatment (3-month mortality rate 6.5% in the infusion group vs. 13.5% in the control group [relative reduction 52%, p = 0.046]; 1-year mortality rate 8.6% in the infusion group vs. 18.0% in the control group [relative reduction 52%, p = 0.020]). CONCLUSIONS Insulin-glucose infusion followed by a multidose insulin regimen improved long-term prognosis in diabetic patients with acute myocardial infarction.
