Improvement in glycemic control following a diabetes education intervention is associated with change in diabetes distress but not change in depressive symptoms

In diabetes patients, depression is correlated with diabetes-specific emotional distress, and observational studies have suggested that diabetes distress may have a greater impact on diabetes outcomes than depression itself. To examine the relative effects of change in depressive symptoms and change in diabetes distress on change in glycemic control, we conducted a diabetes self-management education intervention in 234 type 2 diabetes (T2DM) patients, and measured glycemic control (HbA1c), depressive symptoms (CES-D), and diabetes distress (PAID) at baseline and 6 months. In multiple linear regression, change in depressive symptoms was not associated with change in HbA1c (P = 0.23). Change in diabetes distress was significantly associated with change in HbA1c (P < 0.01), such that a 10-point decrease in diabetes distress (which corresponds to the average change in distress in this study population) was associated with a 0.25% reduction in HbA1c. Change in diabetes distress, and not change in depressive symptoms, was associated with both short- and long-term change in glycemic control for patients with poorly controlled T2DM.     

Trace elements in type 2 diabetes mellitus and their association with glycemic control

BackgroundAlterations in serum levels of trace elements reported in type 2 diabetes mellitus (T2DM) have been linked with induction of T2DM and associated complications.ObjectivesTo assess serum levels of copper (Cu), zinc (Zn) and selenium (Se) in T2DM patients with adequate and poor glycemic control.Patients and methodsThis study was performed at King Khalid University Hospital, Riyadh. A total of 100 consenting T2DM patients comprising of 50 patients with glycated hemoglobin (HbA1c) less than 6.5% and 50 patients with HbA1c more than 6.5% along with a group of 50 normal healthy individuals were included in the study. Serum levels of Cu, Zn and Se were measured by inductively coupled plasma-mass spectrometry (ICP-MS) instrument.ResultsAmong T2DM patients with HbA1c <6.5%, mean serum Cu levels (13.4+4.3µmol/L) were not different from the controls (14.5+1.92µmol/L) whereas Zn (9.9+2.7µmol/Lvs15+3.2µmol/L;p<0.0001) and Se levels (1+0.2µmol/Lvs1.62+0.2µmol/L; p<0.0004) were lower than the controls. Among T2DM patients with HbA1c >6.5% mean serum Cu (18.1+4.1µmol/Lvs14.5+1.9µmol/L; p<0.0001), Zn (15+3.2µmol/Lvs13.5+1.9µmol/L; p<0.009) and Se (1.62+0.2µmol/Lvs1.17+0.16µmol/L;p<0.0001) were significantly higher than the controls. HbA1c% negatively correlated with HbA1c >6.5% (r = -0.302; p<0.03).ConclusionCu, Zn and Se homeostasis was altered in T2DM patients and varied with glycemic control.     

Increased frequency of CD14+HLA-DR-/low cells in type 2 diabetes patients with poor glycemic control

AimsType 2 diabetes (T2DM) is associated with alterations of the immune response and T2DM patients have an increased risk for infections and certain sorts of cancers. Although CD14⁺HLA-DR^-/low cells have emerged as important mediators of immunosuppression in several pathologies, including cancer and non-malignant diseases, the presence of these cells in T2DM is not fully characterized.MethodsIn this study, we evaluated the frequency of CD14⁺HLA-DR^-/low cells in non-obese T2DM patients and their association with glycemic control. Peripheral blood mononuclear cells were isolated from healthy controls (HC, n = 24) and non-obese T2DM patients (n = 25), the population was evaluated by flow cytometry, and an analysis of correlation between cell frequencies and clinical variables was performed.ResultsCD14⁺HLA-DR^-/low monocytes were expanded in patients with T2DM compared to HC regardless of weight. Among the subjects with T2DM, the frequency of CD14⁺HLA-DR^-/low was higher in patients with poor glycemic control (HbA1c > 9%) compared to those with better glycemic control (HbA1c < 9%) and, positively correlated with the years since the diagnosis of T2DM, the age of the patients and the glycemic index.ConclusionsAn increased frequency of CD14⁺HLA-DR^-/low cells in the blood of T2DM patients was recorded. The influence of hyperglycemia seems to be independent of obesity, but related to glycemic control and age.     

Evaluation of glycemic control in patients with type 2 diabetes mellitus in Chinese communities: a cross-sectional study

This study aimed to evaluate the glycemic levels in Chinese patients with type 2 diabetes mellitus (T2DM) and to explore the factors related to the results of glycemic control. A total of 2454 T2DM patients from 11 communities were examined for glycosylated hemoglobin levels and glycemic control options. Potential factors related to the results of glycemic control were analyzed using logistic regression. Of all the patients, 55.3 % achieved the glycemic control target of HbA1c < 7 %. Multivariate analysis showed that male sex (OR 1.345, 95 % CI 1.022–1.769; P = 0.034), higher levels of fasting blood glucose (OR 1.954, 95 % CI 1.778–2.147; P < 0.001), and low-density lipoprotein cholesterol (OR 1.181, 95 % CI 1.020–1.367; P = 0.026) were significantly associated with poor glycemic control. The complexity of antidiabetics was also associated with poor glycemic control (P < 0.05). Compared to diet and exercise, insulin injection was most strongly associated with poor glycemic control (OR 6.210, 95 % CI 4.054–9.514; P < 0.001). Male patients with higher levels of total cholesterol, lower levels of high-density lipoprotein cholesterol, or longer diabetic durations showed poor glycemic control, which was not found in female patients. Glycemic control was not satisfactory in T2DM patients of Nanjing communities. Various factors are associated with poor results of glycemic control.     

Efficacy of a language-concordant health coaching intervention for latinx with diabetes

ObjectiveTo describe the effect of a language-concordant health coaching intervention for Spanish-speaking patients with limited English proficiency (LEP) and uncontrolled Type 2 Diabetes (T2D) on glycemic control, anxiety, depression, and diabetes self-efficacy.Methods64 patients with T2D were randomly assigned to a control or intervention group. Outcomes were assessed by blood work and surveys pre and post intervention.ResultsThe mean sample age was 47.8 years (SD=11.3) and 81% were female. HbA1c was not significantly different between groups at baseline. The intervention group’s HbA1c was significantly lower at times 2 and 3 than in the control arm (p < .01 and p < .001). There were significant reductions in the intervention group’s mean HbA1c levels from baseline 10.37 to midpoint 9.20, p < .001; and from baseline 10.42 to study end 8.14, p < .001. Depression and anxiety scores significantly decreased (p < .05 and p < .001), and diabetes self-efficacy significantly increased (p < .001).ConclusionHealth coaching led to statistically significant and clinically meaningful decreases in HbA1c, depression, and anxiety scores among LEP Latinx adults with uncontrolled T2D.Practice ImplicationsHeath coaching can be conducted in primary care clinics by nurses or advanced practice nurses. The short-term intervention tested here could be adapted to the clinical setting.     

The association of lifestyle and stress with poor glycemic control in patients with diabetes mellitus type 2: a Croatian nationwide primary care cross-sectional study

AimTo assess lifestyle habits and self-reported stress levels among type 2 diabetes mellitus (T2DM) patients and their association with hemoglobin A1c (HbA1c) in general practitioners'' (GP) offices in Croatia.Methods449 GPs from all Croatian regions from 2008 to 2010 consecutively recruited up to 20-25 participants diagnosed with T2DM at least 3 years prior to the study, aged ≥40 years, and scheduled for diabetes control check-ups. The recruitment period lasted six months. Lifestyle habits and self-reported stress were assessed using the questionnaire from the Croatian Adult Health Survey.ResultsThe study included 10 285 patients with T2DM with mean (±standard deviation) age of 65.7 ± 10.05 years (48.1% men). Mean HbA1c level was 7.57 ± 1.58%. 79% of participants reported insufficient physical activity, 24% reported inappropriate dietary patterns, 56% reported current alcohol consumption, 19% were current smokers, and 85% reported at least medium level of stress. Multivariate analysis showed that having received advice to stop drinking alcohol, inadequate physical activity, consumption of milk and dairy products, adding extra salt, and high level of stress were significantly associated with increased HbA1c (P < 0.05).ConclusionPoor glycemic control was more frequent in patients who had several “unhealthy” lifestyle habits. These results suggest that diabetes patients in Croatia require more specific recommendations on diet, smoking cessation, exercise, and stress control.According to Croatian National Diabetes Registry, in Croatian population there are 6.3% of registered type 2 diabetes mellitus (T2DM) patients (1). T2DM contributes to the development of circulatory system diseases, which are among ten leading causes of death in Croatia and which cause significant physical disability. As such, it represents a growing burden to health economy. The total treatment cost of T2DM and its complications in Croatia amounted to 11.49% of the Croatian Health Insurance Fund’s budget in 2009, ie, to 351.7 million EUR: 50.2 million EUR for direct medical costs of diabetes treatment and monitoring, 301.5 million EUR for treatment of diabetes-related chronic complications, and 4.6 million EUR for additional indirect costs (2). It is well established that the risk of microvascular and macrovascular complications is related to glycemia. Average blood glucose levels in the previous 3 months are measured by hemoglobin A1c (HbA1c), which still remains a major therapy monitor in diabetes (3). To reduce the incidence of microvascular disease, the American Diabetes Association’s “Standards of Medical Care in Diabetes” recommends lowering HbA1c to <7.0% (4). Since glucose control requires active patients’ participation and commitment, targeted HbA1c treatment must be individualized (5). Given the tremendous disease burden and financial costs associated with diabetes complications, understanding modifiable predictors of diabetes disease course has great public health importance. T2DM patients are often recommended to control body weight, engage in physical activity, and eat a balanced diet. Regular physical activity is beneficial not only for body weight control, but also for improvement of insulin sensitivity and has been reported to reduce the overall mortality of T2DM patients (6). For these patients, it is also important to consume low-fat, low-salt, high-fiber, and low glycemic load diet (7). Another potentially modifiable behavior that may affect the disease course is alcohol consumption. Moderate alcohol consumption has been associated with better glycemic control than abstinence (8). Apart from the association with the development of T2DM, smoking was also related to higher mortality and morbidity (9,10). Substantial data support the theoretical importance of stress in T2DM, yet there is little direct evidence that stress plays a clinically significant role. Higher stress levels showed no prospective relationship with HbA1c, but higher stress levels attributable to diabetes displayed both cross-sectional and longitudinal relationships with HbA1c (11).According to the Croatian Adult Health Survey (CAHS) 2008, risk factors for T2DM in Croatian adult population were unhealthy nutritional regimen, excessive alcohol consumption, smoking, and lack of physical activity (12). The aim of this study was to investigate the associations between lifestyle habits, self-reported stress, and glycemic control in people diagnosed with T2DM who received medical care in a primary care setting.     

Diabetic patients suffering dengue are at risk for development of dengue shock syndrome/severe dengue: Emphasizing the impacts of co-existing comorbidity(ies) and glycemic control on dengue severity

Background/PurposeThe impact of type 2 diabetes mellitus (DM2) on clinical severity of dengue has not been fully understood. We aimed to assess risk factors for dengue hemorrhagic fever (DHF)/dengue shock syndrome (DSS) and severe dengue (SD) (defined based on the World Health Organization 1997 and 2009 dengue classifications), and additionally identify, among DM2 patients, who are at risk for developing DHF/DSS and severe dengue.MethodsA retrospective analysis of dengue patients diagnosed between 2002 and 2010. Risk factors for development of DHF/DSS/SD were identified using multivariate analysis. To elucidate the impacts of coexisting comorbidity(ies) (i.e., hypertension, chronic kidney disease, old stroke, and/or ischemic heart disease) and glycemic control on clinical outcomes of dengue in DM2 patients, the overall DM2 patients and stratified DM2 patients (HbA1c < 7% vs. HbA1c ≧ 7%), with or without comorbidity(ies), were separately compared to controls (patients without any morbidity).ResultsOf 767 (146 DM2 and 621 controls) included patients, 1.4% suffered DSS and 3.3% SD. While DM2 was an independent risk factor for DSS (adjusted odds ratio [AOR] = 7.473; 95% confidence interval [CI] = 2.221–25.146) and SD (AOR = 6.207; 95% CI = 2.464–15.636), only DM2 patients with additional comorbidity(ies) and suboptimal glycemic control (HbA1c ≧ 7%) had significantly higher incidences of non-shock DHF (60.8% vs. 29%), DSS (8.7% vs. 0.8%) and SD (34.8% vs. 1.1%).ConclusionsThese data could help narrow down the number of targets in the triage for risky DM2 dengue patients to those with suboptimal glycemic control and co-existing comorbidity(ies).     

Glycemic control influences lung membrane diffusion and oxygen saturation in exercise-trained subjects with type 1 diabetes: alveolar-capillary membrane conductance in type 1 diabetes

Lung diffusing capacity (DLCO) is influenced by alveolar-capillary membrane conductance (D _M) and pulmonary capillary blood volume (V _C), both of which can be impaired in sedentary type 1 diabetes mellitus (T1DM) subjects due to hyperglycemia. We sought to determine if T1DM, and glycemic control, affected DLNO, DLCO, D _M, V _C and SaO₂ during maximal exercise in aerobically fit T1DM subjects. We recruited 12 T1DM subjects and 18 non-diabetic subjects measuring DLNO, DLCO, D _M, and V _C along with SaO₂ and cardiac output (Q) at peak exercise. The T1DM subjects had significantly lower DLCO/Q and D _M/Q with no difference in Q, DLNO, DLCO, D _M, or V _C (DLCO/Q = 2.1 ± 0.4 vs. 1.7 ± 0.3, D _M/Q = 2.8 ± 0.6 vs. 2.4 ± 0.5, non-diabetic and T1DM, p < 0.05). In addition, when considering all subjects there was a relationship between DLCO/Q and SaO₂ at peak exercise (r = 0.46, p = 0.01). Within the T1DM group, the optimal glycemic control group (HbA1c <7%, n = 6) had higher DLNO, DLCO, and D _M/Q than the poor glycemic control subjects (HbA1c ≥7%, n = 6) at peak exercise (DLCO = 38.3 ± 8.0 vs. 28.5 ± 6.9 ml/min/mmHg, DLNO = 120.3 ± 24.3 vs. 89.1 ± 21.0 ml/min/mmHg, D _M/Q = 3.8 ± 0.8 vs. 2.7 ± 0.2, optimal vs. poor control, p < 0.05). There was a negative correlation between HbA1c with DLCO, D _M and D _M/Q at peak exercise (DLCO: r = −0.70, p = 0.01; D _M: r = −0.70, p = 0.01; D _M/Q: r = −0.68, p = 0.02). These results demonstrate that there is a reduction in lung diffusing capacity in aerobically fit athletes with T1DM at peak exercise, but suggests that maintaining near-normoglycemia potentially averts lung diffusion impairments.     

Effects of the glucose-lowering rate on cTnI and hs-CRP serum levels in type 2 diabetics

Objectives

The current objective is to evaluate the effect of intensive glycemic control on serum levels of both Cardiac Troponin I (cTnI) and high sensitivity C-reactive protein (hs-CRP) in subjects with type 2 diabetes. Hence, we are trying to find a reasonable glucose-lowering rate associated with type 2 diabetics with and without coronary heart disease.

Methods

A total of 132 type 2 diabetes mellitus without coronary heart disease (T2DM) cases and 135 type 2 diabetes mellitus with coronary heart disease (T2DM+CHD) cases received intensive glycemic control. Serum cTnI and hs-CRP levels were tested before and after intensive glycemic control.

Results

There was no significant difference in the changing amplitude of cTnI and hs-CRP serum levels variation between four glucose-lowering rates in T2DM group (P > 0.05), while this difference was observed in T2DM+CHD group(P < 0.05). During the follow-up, cTnI and hs-CRP serum levels were lower than those before glycemic control in both T2DM and T2DM+CHD groups (P < 0.05).

Conclusions

The glucose-lowering rate in T2DM+CHD group should be no more than 4 mmol L⁻¹ d⁻¹ and the appropriate glucose-lowering rate in T2DM group is no more than 6 mmol L⁻¹ d⁻¹. Serum levels of cTnI and hs-CRP will be increased if the glucose-lowering rate is over this range, which means that cardiovascular endpoints might be induced.     

Impact of ENPP1 K121Q on Change of Insulin Resistance after Web-Based Intervention in Korean Men with Diabetes and Impaired Fasting Glucose

Ectoenzyme nucleotide pyrophosphate phosphodiesterase 1 (ENPP1) gene has been studied in relation to type 2 diabetes mellitus (T2DM) and insulin resistance (IR). We hypothesized that the difference in genotype may be one of the factors that affect the outcome of intervention. We genotyped 448 men with fasting glucose≥5.6 mM/L, including 371 in subjects with K allele (KK) (69 control group [CG]; and 302 intervention group [IG]) and 77 in subjects with Q allele (KQ+QQ) (13 CG and 64 IG). The web-based intervention based on a lifestyle modification was delivered by e-mail once a month for 10 months. In the KK, IG demonstrated significantly decreased levels of fasting serum insulin (FSI) as compared to CG and homeostasis model of assessment of insulin resistance (HOMA-IR). In the KQ+QQ IG group, hemoglobin A1c (HbA1c), FSI and HOMA-IR were significantly decreased, and showed further reduction in the HOMA-IR than KQ+QQ CG. After analysis of covariance, K121Q did significantly influence the change of HbA1c in CG after appropriate adjustment. In a multivariate model, BMI change predicted HOMA-IR change (adjusted β=0.801; P=0.022) in KK IG subjects with T2DM. ENPP1 K121Q did not influence the change in IR. However, individuals with T2DM carrying the K121 variant are very responsive to the effect of BMI reduction on HOMA-IR.

Characteristics Predictive for a Successful Switch from Insulin Analogue Therapy to Oral Hypoglycemic Agents in Patients with Type 2 Diabetes

PurposeThe objective of this study was to investigate clinical and laboratory parameters that could predict which patients could maintain adequate glycemic control after switching from initial insulin therapy to oral hypoglycemic agents (OHAs) among patients with type 2 diabetes (T2D).ResultsOf 275 patients with insulin initiation, 63% switched to OHAs (Group I) and 37% continued insulin (Group II). Of these, 44% were in Group IA and 19% in Group IB. The lowest tertile of baseline postprandial C-peptide-to-glucose ratio (PCGR), higher insulin dose at switching to OHAs, and higher HbA1c level at 6 months after switching to OHAs were all associated with OHA failure (Group IB; p=0.001, 0.046, and 0.014, respectively). The lowest tertile of PCGR was associated with ultimate use of insulin (Group IB and Group II; p=0.029).ConclusionHigher baseline level of PCGR and lower HbA1c levels at 6 months after switching to OHAs may be strong predictors for the successful maintenance of OHAs after switching from insulin therapy in Korean patients with T2D.     

Association between BDNF Polymorphism and Depressive Symptoms in Patients Newly Diagnosed with Type 2 Diabetes Mellitus

PurposeLittle is known about the relationship between brain-derived neurotrophic factor (BDNF) gene polymorphisms and psychiatric symptoms in diabetes patients. We investigated the effects of BDNF Val/66/Met polymorphism, glucose status, psychological susceptibility, and resilience on anxiety and depression symptoms in patients newly diagnosed with type 2 diabetes mellitus (T2DM).Materials and MethodsWe examined biochemical factors and BDNF polymorphism in 89 patients who were newly diagnosed with T2DM. Psychiatric symptoms were investigated with the Hospital Anxiety and Depression Scale (HADS), and the Connor-Davidson Resilience Scale (CD-RISC) and Impact of Event Scale (IES) were used to assess psychological resilience and susceptibility to psychological distress, respectively. Logistic regression analyses were conducted to investigate factors associated with psychiatric symptoms.ResultsWe determined that 62 patients (70%) were Met-carriers. No significant differences were found between the Val/Val homozygous and Met-carrier groups regarding age, sex, body mass index, and clinical factors related to glycemic control and lipid profiles. HADS-anxiety and HADS-depression scores and IES factor scores were higher in the Met-carrier than the Val/Val homozygous group. Hemoglobin A1c (HbA1c) level was significantly inversely correlated with the severity of depressive symptoms. Resilience factors showed significant inverse correlations, and IES factors showed positive correlations with depressive symptom severity. In the logistic regression analysis model, depressive symptoms were significantly associated with HbA1c and BDNF polymorphism, whereas only the hyperarousal factor of the IES scale was associated with anxiety.ConclusionDepressive symptoms are associated with the presence of the Met-carriers and lower HbA1c in patients newly diagnosed with T2DM.     

Diabetic status and the relationship of blood glucose to mortality in adults with carbapenem-resistant Acinetobacter baumannii complex bacteremia

Background/PurposeDiabetes is associated with increased mortality in Acinetobacter baumannii (AB) complex infection. This study investigated the risk factors and relationship of diabetic status and glycemic indices to mortality in patients with carbapenem-resistant (CR) AB complex bacteremia.MethodsRelationship of glycemic indices to mortality were compared in adult diabetes (DM) and nondiabetes (non-DM) patients with CRAB complex bacteremia hospitalized from January 2010 to December 2015 in MacKay Memorial Hospital, Taiwan.ResultsOf 317 patients with CRAB complex bacteremia, 146 (46.06%) had diabetes. DM patients were elderly (mean age of 69.23 years) and the mortality rate was higher (64.38% vs. 52.05%, p = 0.036) than in non-DM patients. By multivariate analysis, septic shock was associated with increased mortality in DM patients. Hypoglycemia was associated with increased mortality in non-DM patients only (100% vs. 50.33%, p = 0.006). The lowest mortality was for the blood glucose range 70–100 mg/dL in non-DM patients (43.24%) and 100–140 mg/dL for DM patients (56.52%). Increased glycemic variability (coefficient of variation (CV) > 40% compared to < 20%) was associated with increased mortality in non-DM patients (86.36% vs. 47.12%, p = 0.003).ConclusionEffects of dysglycemia on mortality due to CRAB complex bacteremia differ according to diabetic status. Mortality was higher in DM patients. In non-DM patients, hypoglycemia and increased CV were associated with increased mortality. The lowest mortality was for the blood glucose range 70–100 mg/dL in non-DM patients and 100–140 mg/dL for DM patients.     

Comparative efficacy of exenatide versus insulin glargine on glycemic control in type 2 diabetes mellitus patients inadequately treated with metformin monotherapy

PurposeComparative efficacy of exenatide versus insulin glargine primarily on glucemic control, and secondarily on body mass index (BMI), lipid profile and blood pressure, in type 2 diabetes mellitus (T2DM) patients suboptimally treated with metformin monotherapy.Material/MethodsForty-seven inadequately treated T2DM patients on metformin assigned to exenatide (n=18) or insulin glargine (n=29) for 26 weeks. Glycosylated hemoglobin (HbA1c), serum lipids, BMI, systolic and diastolic blood pressure, and adverse events, including episodes of hypoglycemia and gastrointestinal symptoms, were recorded.ResultsEither treatment had a similar favorable mean reduction in HbA1c. However, more patients in exenatide group achieved HbA1c ≤ 7% at the 26th week compared with insulin glargine group (p=0.036). Insulin glargine group had significantly more episodes of hypoglycemia compared with exenatide group (p=0.039). Gastrointestinal adverse events were non-significantly higher in the exenatide group. A significantly greater BMI reduction was observed in exenatide group, whereas BMI was not altered in insulin glargine group. Total and LDL cholesterol (p=0.012), and triglycerides (p=0.016) significantly decreased, whereas HDL cholesterol increased (p=0.021) in the exenatide group, whereas only total cholesterol decreased in insulin glargine group. Changes in systolic and diastolic blood pressure were insignificant in both groups.ConclusionsExenatide provided similar reduction in HbA1c, but fewer episodes of hypoglycemia, compared with insulin glargine. Exenatide had also a favorable effect on weight loss, although more gastrointestinal adverse events. Exenatide may provide a justified alternative in second line treatment of T2DM, but more trials are required to elucidate its long-term safety and cost-effectiveness.     

Patient-physician interpersonal processes of care at the time of diabetes treatment intensification and their links to patient outcomes

ObjectiveTo investigate how patient-physician interpersonal processes of care are related to levels of diabetes-related distress, diabetes medication-taking behavior, and HbA1c during conversations with patients about intensifying medication.MethodsWe randomly recruited 1270 patients from diabetes specialty clinics in Tehran, Iran who were taking an additional oral diabetes medication or starting insulin during the prior 3 months. This interviewer-administered cross-sectional survey assessed multiple aspects of patient-physician interpersonal processes, diabetes-related distress, and diabetes medication-taking. Clinical history and HbA1c were collected from electronic medical records. Regression estimates and Structural Equation Modeling were used to test associations.ResultsSome communication scales indicated a significant relationship with total diabetes distress (P < 0.001). Diabetes medication-taking was associated with less diabetes distress (adjusted odds ratio [aOR]=0.45, P < 0.001), lower Hurried Communication (aOR=0.72, P = 0.013), higher Elicited Concerns (aOR=1.30, P = 0.012), and higher Explained Results (aOR=1.41, P < 0.001) scores. SEM analyses showed medication-taking behavior was associated with a 0.68 decrease in HbA1c. Hurried Communication and diabetes distress were directly associated with HbA1c.ConclusionAspects of patient-physician interpersonal processes at the time of intensifying diabetes treatment may be related to experiencing less distress, effective medication-taking, and improved HbA1c.Practice implicationsThe results are intended to inform communication strategies that physicians might incorporate into practice.

Improving empowerment,motivation, and medical adherence in patients with poorly controlled type 2 diabetes: A randomized controlled trial of a patient-centered intervention

ObjectiveTo test whether an intervention consisting of four patient-centered consultations improves glycemic control and self-management skills in patients with poorly regulated type 2 diabetes (T2DM), compared to a control group receiving usual care.MethodsUnblinded parallel randomized controlled trial including 97 adults diagnosed with T2DM ≥ 1 year and hemoglobin A1c (HbA1c) levels ≥ 8.0% (64 mmol/mol). Consultations incorporated tools supporting self-reflection, learning processes, and goal setting. Primary outcome was HbA1c. Secondary outcomes were autonomy support, motivation, self-management skills, and well-being.ResultsAverage HbA1c decreased slightly in both groups. Autonomy support and frequency of healthy eating were significantly higher in the intervention group. Most participants in the intervention group chose to set goals related to diet and physical exercise. Implementation of the intervention was inconsistent.ConclusionDespite increased autonomy support and individual goal-setting, the intervention was not superior to usual care in terms of glycemic control. More research is needed on how individual preferences and goals can be supported in practice to achieve sustainable behavior changes.Practice ImplicationsThe intervention promoted participant engagement and supported exploration of participants’ challenges and preferences. Further exploration of more flexible use of tools adapted to individual contexts is recommended.     

Low-dose IL-2 therapy restores imbalance between Th17 and regulatory T cells in patients with the dermatomyositis combined with EBV/CMV viremia

ObjectiveDermatomyositis (DM) is closely associated with infection, the levels of peripheral lymphocyte subpopulations are rarely studied in patients with DM combined with Epstein-Barr virus (EBV)/cytomegalovirus (CMV) infection. Here, we aimed to observe the level of lymphocyte subsets, especially Th17, regulatory T (Treg) cells in DM combined with EBV/CMV viremia, and explore the effects of short-term low-dose IL-2.Methods34 DM patients combined with EBV/CMV viremia (DM infection group), 31 DM patients without infection (DM non-infection group) and 20 healthy controls were entrolled in our study. In DM infection group, 13 patients received low-dose IL-2 at 0.50 Million IU/day for a five-day course on the basis of conventional treatment. All subjects had completed the decetion of the absolute numbers of lymphocytes subsets in peripheral blood by flow cytometry.ResultsThe infection group had significant decreases levels of total T, total B, NK, CD4 + T cells and CD4 + T subsets (Th1, Th2, Th17, Treg cells). Compare to the healthy controls, Th17 cells was significantly reduced in the infection group, but not in the non-infection group (P < 0.001 vs. P = 0.171). After low-dose IL-2 therapy, the levels of Treg (P = 0.001) cells and Th17 cells were significantly elevated, re-balancing the Th17 and Treg proportions.ConclusionsThe absolute numbers of Th17 and Treg cells in DM patients with EBV/CMV viremia is further reduced. In addition to Treg cells, a decrease in Th17 cells may be also a crucial feature. Low-dose IL-2 treatment may be beneficial and safe prospect immunomodulatory therapy to restores imbalance between Th17 and Treg cells for these patients. Low-dose IL-2 therapy may be a new prospect field with some challenges such as long-term immunoregulatory utility in various virus infection.     

Retinol binding protein 4 correlates with and is an early predictor of carotid atherosclerosis in type 2 diabetes mellitus patients

The association of retinol binding protein 4 (RBP4) with atherosclerosis of the carotid artery in type 2 diabetes mellitus (T2DM) remains undefined. We aimed to investigate the correlation of RBP4 expression with atherosclerosis of the carotid artery in T2DM. A total of 1,076 subjects were investigated for intima-media thickness of the bilateral common carotid arteries, and they were divided into three groups: in group I, patients had normal neck vascular ultrasound, in group II, intimal carotid artery media thickness was equal to or more than 1 mm, and in group III, carotid artery plaque was present. Height, weight, blood pressure (BP), fasting plasma glucose (FPG), hemoglobin A1c (HbA1c), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), apolipoprotein A-1 (apoA-1), apolipoprotein B (apoB) and lipoprotein (a) [Lp(a)] were determined by routine laboratory methods. RBP4 and high sensitivity C reactive protein (HsCRP) were measured by an enzyme-linked immuno-sorbent assay, and insulin concentration was measured by an electrochemiluminescence sandwich immunoassay. Duration of diabetes, waist and BP, FPG, HbA1c, TG, TC, LDL-C, APOB, Lp(a), HsCRP, RBP4 and homeostasis model assessment insulin resistance index (HOMA-IR) were significantly lower in group I than in the other two groups (P<0.01, P<0.01). Plasma levels of HbA1c, RBP4, LDL-C, TC, HOMA-IR, HsCRP and Lp(a), waist and BP were significantly increased in group III than in group II (P<0.01). Multivariate logistic regression analysis showed that there were seven factors associated with the occurrence of carotid artery atherosclerosis and its risks in descending order were: high LDL-C, high waist, high HsCRP, duration of diabetes, high HOMA-IR, HbA1c and high RBP4. Our finding supported that RBP4 was positively correlated with carotid atherosclerosis in patients with T2DM and could be used as an early predictor of cardiovascular disease.     

艾塞那肽对新诊断2型糖尿病患者骨代谢的影响

 目的:观察24周胰高糖素样肽1受体激动剂艾塞那肽治疗对新诊断2型糖尿病患者骨密度及骨转化标志物的影响。方法:20名新诊断2型糖尿病患者,予以艾塞那肽治疗24周。治疗前后检测体重、空腹血糖（FPG）、餐后2 h血糖（PBG）、糖化血红蛋白（HbA1c）、空腹胰岛素（FINS）、骨密度、体脂分布和空腹血清中的骨转化标志物水平,包括骨形成标志物骨钙素（OC）、骨吸收标志物Ⅰ型胶原交联羧基末端肽（CTX）和抗酒石酸酸性磷酸酶5b（TRAcP5b）。结果:新诊断2型糖尿病患者经过24周艾塞那肽治疗后,FPG、PBG和HbA1c降低（P<0.01）,HOMA胰岛素抵抗指数改善(P<0.05),体重及体脂含量下降（P<0.05）;虽然患者OC水平下降,骨吸收标志物（CTX和TRAcP5b）水平上升,骨密度增加,但均未达统计学意义。结论: 24周艾塞那肽治疗改善新诊断2型糖尿病患者的血糖和胰岛素抵抗,使体重及体脂含量下降,但尚未对患者骨密度及骨转化标志物产生影响。
