ObjectiveTo discuss the characteristics of coronary artery disease in patients with type 2 diabetes using coronary angiography of Dual Source CT.
MethodsWe collected the clinical data of patients who underwent coronary angiography of Dual Source CT between December 2010 and November 2012 in Sichuan Provincial People's Hospital and Sichuan Orthopedic Hospital. A total of 302 patients (74 with type 2 diabetes, and 228 with no diabetes) were examined with CT coronary angiography. All images were comprehensively assessed. Types of plaques and luminal narrowing were evaluated.
ResultsPatients with type 2 diabetes had more plaques (P<0.05), especially mixed plaques and non-calcified plaques, than non-diabetic patients (P<0.05). The proportions of calcified plaque, mixed plaques, non-calcified plaque in patients with type 2 diabetes were 29.1%, 41.1%, 29.8%, respectively. The proportions of calcified plaque, mixed plaques, non-calcified plaque in patients with nondiabetic patients were 39.7%, 36.0%, 24.3%, respectively. The difference of the composition between diabetes and nondiabetic was significant (P<0.05). There were more mild, moderate and severe narrowing in type 2 diabetic patients than those in non-diabetic patients (P<0.05).
ConclusionCoronary angiography of CT depicts a high plaque burden in patients with type 2 diabetes mellitus (mixed plaque is the most common type), which may cause stenosis easily.
ObjectiveTo systematically evaluate the safety of dipeptidyl peptidase-4 (DPP-4) inhibitors on the risk of cardiovascular events in type 2 diabetes mellitus (T2DM) patients.
MethodsDatabases such as the Cochrane Library, PubMed, Elsevier ScienceDirect and EMbase were searched to collect randomized controlled trials (RCTs) about DPP-4 inhibitors for T2DM patients from inception to February 2014. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and assessed the methodological quality of included studies. Then, meta-analysis was performed using RevMan5.2 software.
ResultsA total of 20 RCTs involving 10 402 patients were included. The results of meta-analysis showed that:there were no significant differences between the DPP-4 inhibitors group and the control group in the cardiovascular adverse events (RR=0.86, 95%CI 0.62 to 1.20, P=0.38) and acute coronary syndrome (RR=0.66, 95%CI 0.37 to 1.17, P=0.15). Subgroup analyses by type of liptins and durations showed there were lower risks of adverse cardiovascular events in the DPP-4 inhibitors group of the sitagliptin subgroup (RR=0.49, 95%CI 0.29 to 0.82, P=0.007) and the duration of ≥52 weeks subgroup (RR=0.62, 95%CI 0.39 to 0.97, P=0.04). No significant difference was found between the two groups in hypertension events (RR=1.09, 95%CI 0.84 to 1.40, P=0.52).
ConclusionThe DPP-4 inhibitors are relatively safe. In the long-term treatment of T2DM, the sitagliptin could not only effectively control the level of blood sugar but also might obtain benefits in cardiovascular aspects.
ObjectivesTo systematically review the detection rate of depression in Chinese individuals with type 2 diabetes mellitus (T2DM).MethodsPubMed, EMbase, The Cochrane Library, CBM, CNKI, WanFang Data and VIP databases were electronically searched to collect observational studies on the detection rate of depression in Chinese with T2DM from inception to January, 2019. Two reviewers independently screened literature, extracted data and evaluated the quality of included studies. Meta-analysis was performed by R 3.6.1 software.ResultsA total of 29 studies involving 96 557 cases were included. Meta-analysis results showed that the total detection rate of depression in Chinese with T2DM was 27% (95%CI 24% to 30%). Subgroup analysis showed that the detection rate of depression in female was 32% (95%CI 20% to 45%), and in male was 26% (95%CI 18% to 37%). The detection rate of depression in rural areas was 36% (95%CI 18% to 54%), and in urban areas was 30% (95%CI 16% to 43%). The detection rate of depression in individuals aged 60 and above was 31% (95%CI 24% to 39%), and in individuals aged less than 60 was 23% (95%CI 10% to 36%). Individuals with a primary school education and below, a middle or high school education and college degree and above education had detection rate of 31%, 23% and 22%, respectively. Individuals with diabetes duration less than 5 years, 5 to 10 years and more than 10 years had detection rates of 23%, 25% and 30%, respectively. Individuals with and without complications had detection rates of 43% and 26%, respectively. The detection rates of mild and moderate to major depression were 20% and 10%, respectively.ConclusionsThe detection rate of depression in Chinese with T2DM is high. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusion.
Objective
To explore the correlation between blood glucose and self-management behaviors in patients with type 2 diabetic mellitus before initial basal insulin therapy.
Methods
A convenient sample of 200 patients with type 2 diabetic mellitus who were hospitalized in a tertiary hospital from February to August 2016 were enrolled in the study on a voluntary basis. Patients’ demographic information, fast blood glucose, glycosylated hemoglobin, and scores of diabetes self-care activities were gathered through questionnaires.
Results
A total of 193 valid questionnaires were recovered. Before starting basal insulin therapy, the mean blood glucose and the mean glycosylated hemoglobin of the 193 patients were (12.22±3.95) mmol/L and (10.01±2.38)%, respectively, with 12 patients (6.22%) meeting the goal of fasting blood glucose ≤7 mmol/L and 18 patients (9.33%) meeting the goal of glycosylated hemoglobin <7%, respectively. The total score of self-care activities was 26.76±14.77, in which 3 patients (1.55%) performed well. Spearman analysis demonstrated that the total score of self-care activities was negatively correlated with fast blood glucose ( r=–0.401, P<0.001) and glycosylated hemoglobin (r=–0.227, P=0.028).
Conclusions
The blood glucose levels and self-management behaviors in diabetic patients at the beginning of initial basal insulin therapy are not optimistic. Enhanced management of type 2 diabetic patients with initial basal insulin therapy is the prerequisite to promote diabetes self-care activities.
ObjectiveTo explore the association between prediabetes and early vascular cognitive impairment (VCI) in patients with acute cerebral infarction. MethodsNon-diabetes mellitus patients with first-ever acute cerebral infarction hospitalized in the Department of Neurology, the First Affiliated Hospital of Henan University of Science and Technology between January and April 2019 were retrospectively enrolled. The enrolled patients were divided into prediabetes group and normal blood glucose group according to the level of glycosylated hemoglobin, and the patients were divided into normal cognitive function group and cognitive impairment group according to the Montreal Cognitive Assessment score. The general information and clinical related data of the included patients were compared. Results A total of 129 patients were enrolled. Among them, 46 cases were in the prediabetes group and 83 cases were in the normal blood glucose group. There were 82 cases in the normal cognitive function group and 47 cases in the cognitive impairment group. Multivariate logistic regression analysis showed that compared with the normal blood glucose group, the prediabetes group was associated with early VCI in patients with acute cerebral infarction [odds ratio (OR)=4.172, 95% confidence interval (CI) (1.786, 9.754), P=0.001]; the higher the NationalInstitutes of Health Stroke Scale score at the first admission was, the higher the risk of early VCI was [OR=1.379, 95%CI (1.183, 1.650), P<0.001]. Conclusion In patients with first-ever acute cerebral infarction, prediabetes is associated with early VCI.
Due to the complexity of etiology and a lot of complication of diabetes mllitus, the reliable conclusion of studies of etiology and treatment of diabtets mellitus should rely on randomized controlled trial and systematic review. Alongside the development of meta-analysis, systematic reviewes have provided many beneficial information, including gene mutation and diabetes mellitus, evaluation of risk factors, diagnostic test and treatment of diabets mellitus.
Objective
To investigate the gastrin level in patients with type 2 diabetes mellitus (T2DM) with gastroesophageal reflux disease (GERD), and analyze the possible mechanism of gastrin in the pathogenesis of T2DM combined with GERD.
Methods
Thirty-eight patients with T2DM combined with GERD treated between January 2013 and January 2015 were designated as group A; 40 patients with T2DM only were regarded as group B; 36 patients with GERD only were regarded as group C; and another 40 healthy volunteers who underwent physical examination at the same period were regarded as group D. The fasting serum levels of gastrin were measured and compared among the above four groups.
Results
The fasting serum level of gastrin was significantly higher in group A [(116.53±22.02) pg/mL] than group B [(101.89±20.76) pg/mL], group C [(90.04±21.16) pg/mL], and group D [(92.48±19.69) pg/mL] (P<0.01). The fasting serum level of gastrin in group B was significantly higher than group C and D (P<0.05). There was no significant difference between group C and D in terms of fasting serum level of gastrin (P>0.05).
Conclusions
There is a high level of gastrin in patients with GERD combined with T2DM. Abnormal secretion of gastrin may be closely related with the occurrence and development of T2DM and GERD.
ObjectiveTo study the correlation of postoperative cognitive dysfunction (POCD) with type-2 diabetes and glycosylated hemoglobin (HbA1c) levels in elderly patients.
MethodsA total of 140 elderly patients who were going to undergo non-cardiothoracic surgery in our hospital between January 2011 and February 2013 were included in this study.ASA classification was between I and Ⅲ.There were 78 males and 62 females,aged between 65 and 86 years old.Group A had 70 patients with diabetes,while group B had another 70 corresponding patients without diabetes.One day before surgery and a week after surgery,Mini-mental State Examination (MMSE) and Montreal Cognitive Functioning Scale (MoCA) were used to test patients'cognitive function,and the incidence of POCD was compared between the two groups.Group A patients,according to HbA1c levels,were divided into group AH (HbA1c>7.5%) and group AL (HbA1c<7.5%).And we compared the relationship between group AL and group B,and the relationship between group AH and group B.
ResultsThe incidence of POCD in group A was significantly higher than that in group B (P<0.05).Group AH had a significantly higher incidence of POCD than group AL (P<0.05).No significant difference was found in fasting plasma glucose among the groups.
ConclusionElderly diabetic patients with poor glycemic control is a risk factor for POCD occurrence,but fasting glucose as a predictor of POCD is not as good as HbA1C.
Objective To summarize the relationship of diabetes and its complications with microRNA. Methods Domestic and international researches were collected by searching to summarize the role of microRNA in diabetes and its complications. Results MicroRNA could affect the secretion of insulin and interfer metabolism of gulcose in fat cells， muscle cells， and liver cells， which resulting in insulin resistance. At the same time， the microRNA also played an role in damage of vascular endothelial cells and myocardial cell in diabetes. Conclusion MicroRNA acts an important role in the process of diabetes and its complications.
ObjectiveTo compare the clinical features of bacterial liver abscess (BLA) with or without diabetes and provide reference for clinical diagnosis and treatment.MethodsThe clinical data of 312 patients with BLA admitted to Huaian First People’s Hospital of Nanjing Medical University from January 2016 to January 2020 were collected. The differences in the clinical symptoms and signs, results of laboratory, imaging, etiological tests, treatment methods, and outcomes of the patients between with and without diabetes were compared.ResultsA total of 312 patients with BLA were collected, 128 BLA patients with diabetes and 184 BLA patients without diabetes. ① There were no significant differences in gender and age between patients with and without diabetes, but the boby mass index of BLA patients with diabetes was higher than that of the patients without diabetes [(25.54±4.99) kg/m2 versus (23.75±3.92) kg/m2, t=3.546, P<0.001]. ② In terms of etiology, the main cause of BLA was the biliary tract infection [37.18% (116/312)]. The incidence of cryptogenic infections in the BLA patients with diabetes was significantly higher than that of the BLA patients without diabetes [39.06% versus 26.63%, χ2=5.386, P=0.020]. ③ In terms of clinical manifestations, the fever was the main symptom of BLA [97.76% (305/312)]. The incidences of abdominal pain and percussion pain in the liver area of BLA patients with diabetes were significantly lower than those in the BLA patients without diabetes [32.03% versus 51.63%, χ2=11.793, P=0.001; 15.63% versus 30.98%, χ2=9.572, P=0.002]. ④ In terms of laboratory tests, compared with the patients without diabetes, the albumin level was lower [(30.88±5.25) g/L versus (33.67±4.33) g/L, t=–5.139, P<0.001], the procalcitonin level and neutral cell ratio were higher [(44.22±39.56) μg/L versus (36.03±22.73) μg/L, t=2.312, P=0.021; (86.68±7.05)% versus (80.73±8.12)%, t=6.710, P<0.001] in the patients with diabetes. ⑤ In terms of imaging findings, the BLA was mainly single abscesses [77.56% (242/312)] and mainly in the right lobe [66.34% (207/312)]. ⑥ In terms of microbiological examination, the bacterial positive detection rate of all patients was 71.15% (222/312). The main pathogen was Klebsiella pneumoniae [71.62% (159/222)]. The Klebsiella pneumoniae infection rate in the BLA patients with diabetes was higher than that in the BLA patients without diabetes [79.30% versus 66.67%, χ2=4.161, P=0.041]. ⑦ The septic shock occurred in 20 (6.41%) patients with BLA. After treatment of all patients, 4 cases of BLA with diabetes and 2 cases of BLA without diabetes died. The patients who died all came from septic shock.ConclusionsClinical manifestations of BLA patients with diabetes are atypical and main infection is Klebsiella pneumoniae. When BLA combined with septic shock, individual treatment strategy should be chosen basing on actual situation of patient.
