Aims: To determine the prevalence of diabetes self-care activities among type 2 diabetes patients and examine the association between socio-demographic and clinical parameters, diabetes self-care activities, and glycemic control among type 2 diabetes patients.Methods: A cross sectional study was conducted among patients with diabetes (n = 123) at the Sultan Bin Abdulaziz Humanitarian City (SBAHC). A regression model was used to examine the variables that predicted glycemic control. Moreover, a regression analysis examining the effect of each self-efficacy subscale on its respective diabetes self -management (DSM) behavior was carried out.Results: The most frequently reported DSM behaviors were foot care followed by medication taking self-management behavior. The least frequently reported DSM behaviors were exercise self-management behavior and blood sugar testing behavior. Self-efficacy was associated with higher levels of diet, exercise, blood sugar testing, and medication taking self-management behaviors. Diet self-management behaviors and oral hypoglycemic agents (OHA) use were significantly independent predictors of glycemic control HbA1c <7% (53 mmol/mol).Conclusions: The findings can serve to help clinicians have a better understanding on the extent to which different self-efficacy parameters have an influence on self-management behaviors, which will in turn lead to better glycemic control and thus improved HbA1c levels.

Aims: Increasing carotid intima-media thickness (CIMT) is associated with incident heart failure (HF). We investigated whether this association differs by diabetes status.Methods: We characterized 13,590 Atherosclerosis Risk in Communities Study participants free of baseline HF into normal fasting glucose (NFG, glucose <100mg/dl), impaired fasting glucose (IFG, glucose 100-125mg/dl), and type 2 diabetes (T2D, glucose ≥126mg/dl, self-report, or use of diabetes drugs). CIMT was assessed by B-mode ultrasound. Incident HF was defined using ICD-9 or 10 codes from hospitalizations and death certificates. Cox regression was used to estimate hazard ratios (HR) for incident HF, adjusting for age, sex, race, education, hypertension medication, blood pressure, BMI, waist circumference, HDL, LDL, triglycerides, lipid-lowering medication, smoking, alcohol, serum creatinine, and interim CHD.Results: T2D participants had higher mean CIMT (0.79±0.20mm), compared to IFG (0.75±0.19mm) and NFG (0.70±0.17mm) (p<0.0001). Over 20.6years of median follow-up, 15% developed HF. Rates of HF (per 1000 person-years) were substantially higher for those with T2D (24.7), compared to IFG (7.7) and NFG (5.8). In adjusted analyses, the CIMT-HF association was significantly modified by diabetes status (Pinteraction=0.015): for NFG (HR per SD increase in CIMT: 1.27; 95%CI: 1.20-1.34), IFG (HR 1.18; 95%CI: 1.11-1.25) and T2D (HR 1.12; 95%CI: 1.05-1.21).Conclusions: CIMT is associated with increased risk of HF, particularly among persons without diabetes. Due to a high absolute risk of HF among adults with T2D, CIMT may be a less reliable predictor. [ABSTRACT FROM AUTHOR]

Aims: To compare the efficacy on glycemic parameters between a 12-week administration of once-daily linagliptin and thrice-daily voglibose in Japanese patients with type 2 diabetes.Methods: In a multi-center, randomized, parallel-group study, 382 patients with diabetes were randomized to the linagliptin group (n=192) or the voglibose group (n=190). A meal tolerance test was performed at weeks 0 and 12. Primary outcomes were the change from baseline to week 12 in serum glucose levels at 2h during the meal tolerance test, HbA1c levels, and serum fasting glucose levels, which were compared between the 2 groups.Results: Whereas changes in serum glucose levels at 2h during the meal tolerance test did not differ between the groups, the mean change in HbA1c levels from baseline to week 12 in the linagliptin group (-0.5±0.5% [-5.1±5.4mmol/mol]) was significantly larger than in the voglibose group (-0.2±0.5% [-2.7±5.4mmol/mol]). In addition, there was significant difference in changes in serum fasting glucose levels (-0.51±0.95mmol/L in the linagliptin group vs. -0.18±0.92mmol/L in the voglibose group, P<0.001). The incidences of hypoglycemia, serious adverse events (AEs), and discontinuations due to AEs were low and similar in both groups. However, gastrointestinal AEs were significantly lower in the linagliptin group (1.05% vs. 5.85%; P=0.01).Conclusions: These data suggested that linagliptin monotherapy had a stronger glucose-lowering effect than voglibose monotherapy with respect to HbA1c and serum fasting glucose levels, but not serum glucose levels 2h after the start of the meal tolerance test.

Objectives: To compare the cardiovascular and metabolic outcomes of Insulin versus non-insulin glucose lowering therapy (GLT).Methods: We included randomised control trials (RCTs) which randomised patients aged >18years with Type 2 Diabetes (T2D) to insulin vs non-insulin GLT. We used risk ratios (RR), risk difference (RD) and odds ratios (OR) with 95% confidence interval (95%CI) to analyse the treatment effects of dichotomous outcomes and mean differences (with 95% CI) for continuous outcomes.Results: We included 18 RCTs with 19,300 participants. There was no significant difference in the risk of all-cause mortality and CV events between the groups (RR=1.01; 95%CI: 0.96-1.06; p=0.69). In 16 trials, insulin showed greater efficacy in glycaemic control (mean diff=-0.20; 95%CI: -0.28 to -0.11) but the proportion achieving HbA1c level of either ⩽7.0% or 7.4% (53 or 57mmol/mol) was similar in both (OR=1.55; 95%CI=0.92-2.62). The non-insulin group had a significant reduction in weight (mean diff=-3.41; 95%CI: -4.50 to -2.32) and an increase in the proportion of adverse events (54.7% vs 45.3%, p=0.044), but the insulin group showed an (RR=1.90; 95%CI: 1.44-2.51) increased risk of hypoglycaemia.Conclusion: There was no difference in the risk of all-cause mortality and adverse cardiovascular (CV) events between Insulin and non-insulin GLTs. Insulin was associated with superior reduction in HbA1c; least reduction in weight and higher risk of hypoglycaemia. Both showed similar proportion of patients achieving HbA1c target. Non-insulin GLTs were associated with a higher risk in reported adverse drug events. [ABSTRACT FROM AUTHOR]

Background: This study examines how socioeconomic factors are associated with prevalence and self-management of diabetes among ethnic minority groups in the rural Yunnan province, which has the most ethnic minority groups per province in southwest China.Methods: A cross-sectional survey was carried out in 2014 in a rural southwest population consisting of 5532 consenting individuals aged ⩾35years. Information about participants' demographic characteristics, as well as diabetes diagnosis, treatment, and self-management behaviors, were obtained using a standard questionnaire. Fasting blood sugar levels were recorded for each individual. A socioeconomic position (SEP) index was constructed using principal component analysis.Results: The age-standardized prevalence of diabetes in the study population was 4.8%. In persons with diabetes, 23.1% regularly self-monitored blood glucose, 43.2% adhered to taking prescribed anti-diabetic drugs or insulin injections, and 63.1% took at least one measure to control blood glucose. Individual educational level was found to be negatively associated with the prevalence of diabetes, whereas individuals with greater household assets and higher SEP were more likely to be suffered from diabetes. Persons with diabetes with greater household assets, higher level of education, and higher SEP had a greater probability of regularly self-monitoring blood glucose, compliance to prescribed medicines, and taking measures to control diabetes. Access to medical services was positively associated with regularly self-monitoring blood glucose and compliance to prescribed medicines.Conclusions: Socioeconomic disparities in diabetes prevalence and self-management do exist. Future interventions to further control diabetes and improve diabetes management must be tailored to address socioeconomic factors. [ABSTRACT FROM AUTHOR]

Aims: To investigate treatment patterns and achievement of glycemic targets in patients with type 2 diabetes mellitus treated with basal insulin in a real-world setting, and to determine physicians' beliefs and practices regarding these patients.Methods: This study had two components; a retrospective analysis using a US claims database of patient and treatment data, and a survey of physicians' beliefs and practices.Results: A total of 39,074 patients treated with basal insulin were included in this analysis. The proportion of patients achieving HbA1c<7.0% (53mmol/mol) was similar in ongoing basal insulin users at baseline (26%) and at 3months follow-up (27%). The number of new initiators achieving HbA1c<7.0% (53mmol/mol) increased from baseline (11%) to 3months (27%). In the physician survey component, the majority of physicians indicated they would continue to increase basal insulin dose as long as was needed to reach HbA1c/fasting blood glucose goals (85% of physicians treating 'not on-goal' patients, 78% of physicians treating 'on-goal' patients). Physician-perceived barriers to insulin intensification included patient's lifestyle, non-adherence, and concerns about out-of-pocket costs.Conclusions: A large proportion of patients on insulin-based therapy fail to reach glycemic goals. More education of clinicians may improve insulin intensification rates and increase the proportion of patients reaching glycemic targets. [ABSTRACT FROM AUTHOR]

In a survey of Australian drivers with type 1 diabetes, three-quarters reported not checking their blood glucose consistently before driving. They reported lack of health professional recommendation of this behaviour, less concern about safety, and preference for consuming fast-acting glucose, which may be less effective for mitigating risk.

Aims: To describe the degree of diffusion and acceptance of national guideline on screening and diagnosis of gestational diabetes (GDM) among Italian diabetes centers and to detect possible areas for benchmarking.Methods: In 2013 the Italian Diabetes in Pregnancy Study Group structured a national survey, focused on GDM screening and diagnostic procedures, that was administered to diabetologists.Results: Overall, 122 diabetologists of 122 different diabetes centers (21.7% territorial, 78.3% hospital/University) completed the questionnaire. All respondents declared to execute a 75 g-oral glucose tolerance test (OGTT) as diagnostic test. Almost one in five centers preferred a universal screening procedure, the others executing a selective risk factors-based screening. In patients at high risk for GDM the OGTT was performed at 16-18 weeks' gestation in 84.0% of the cases; only 6.5% of respondents preferred to execute it as soon as possible; and 9.5% used to wait until 24-28 weeks' gestation. In the case of fasting plasma glucose (FPG) ≥ 5.1 mmol/l (92 mg/dl), two third of respondents used to proceed with the execution of the complete diagnostic OGTT, the others considering sufficient the FPG value for the diagnosis.Conclusions: Good level of reception of national recommendations was documented. The diagnostic procedure was generally accepted and applied. Some criticisms were specifically linked to the choice of universal or risk factor-based screening procedure, and to the right time for executing the OGTT in women at high risk.

Abstract: Aims: To utilise whole-system analysis of capillary glucose measurement results to examine trends in timing of glucose monitoring, and to investigate whether these timings are appropriate based on observed patterns of hypoglycaemia. Methods: Near-patient capillary blood glucose results from eight acute hospitals collected over 57 months were analysed. Analysis of frequency of measurement, and measurements in the hypoglycaemic (<4mmol/l) and severe hypoglycaemic (<2.5mol/l) range per time of day was made. Results: 3345241 capillary glucose measurements were analysed. 1657594 capillary blood glucose values were associated with 106624 admissions in those categorised as having diabetes. Large peaks in frequency of glucose measurements occurred before meals, with the highest frequency of capillary glucose measurement activity being seen pre-breakfast. Overnight, an increase in measurement activity was seen each hour. This pattern was mirrored by frequency of measured hypoglycaemia. 27968 admissions (26.2%) were associated with at least one hypoglycaemic measurement. A greater proportion of measurements were within the hypoglycaemic range overnight with 61.7% of all hypoglycaemia between 2100 and 0900h, with peak risk of measured capillary glucose being hypoglycaemic between 0300 and 0400h. Conclusions: Hypoglycaemic is common with the greatest risk of hypoglycaemia overnight and a peak percentage of all readings taken being in the hypoglycaemic range between 0300 and 0400h. Measurement activity overnight was driven by routine, with patterns of proportion of measurements in the hypoglycaemic range indicating that there may be a significant burden of undiscovered hypoglycaemia in the patients not routinely checked overnight.

Abstract: Commonly used tests for the diagnosis of diabetes include measurements of fasting plasma glucose levels and the oral glucose tolerance test (OGTT). Recently, a hemoglobin A1C (A1C) level of 6.5% has been included as a criterion for diabetes diagnosis by the American Diabetes Association. We aimed to determine appropriate A1C cutoff values for identifying patients with diabetes or prediabetes, including impaired glucose tolerance and impaired fasting glucose among Korean adults and to determine whether these cutoffs vary according to age. We recruited 4616 adults without a history of diabetes from 10 university hospitals. A 75-g OGTT and A1C sampling were performed in all examinees. Pointwise area under the receiver operating characteristic curve was used to evaluate the diagnostic accuracy of the A1C cutoff. An A1C threshold of 6.1% proved to be the optimal limit for diagnosing diabetes, with 63.8% sensitivity and 88.1% specificity. The cutoff value increased with age (5.9% in 18–39 years, 6.2% in 40–64 years, and 6.4% in older than 65 years) and were similar for men and women. An A1C cutoff of 5.7% had reasonable sensitivity (48.6%) and specificity (65.7%) for the identification of prediabetes. Further prospective studies should be carried out to determine whether the application of age-specific diagnostic criteria is appropriate. [Copyright &y& Elsevier]

Abstract: Aims: Polymorphisms of KCNQ1 were previously associated with type 2 diabetes (T2DM) in select Caucasian and non-Caucasian populations. We investigated the association of rs231361, rs231359, rs151290, rs2237892, rs2283228, rs2237895, and rs2237896 KCNQ1 polymorphisms with T2DM in Tunisian Arabs. Subjects and methods: Subjects comprised 900 T2DM patients and 600 normoglycemic controls. KCNQ1 genotyping was done by allelic discrimination (real-time PCR) and PCR-RFLP methods; the contribution of KCNQ1 polymorphisms to T2DM were analyzed by Haploview and regression analysis. Results: Minor allele frequency (MAF) of the 7 tested KCNQ1 variants was comparable between T2DM cases and controls. Mild association of rs2237892 genotypes with T2DM was seen (P =0.014), highlighted by the significant association of the C/T genotype with increased T2DM risk (OR, 2.11; 95%CI, 1.25–3.53), after adjusting for BMI, gender, systolic and diastolic blood pressure, and serum lipid profile. Heterogeneity in linkage disequilibrium pattern between tested KCNQ1 variants analyzed was seen. Two-locus (rs231361 and rs231359) and 5-locus (remaining 5 SNPs) haplotype analysis did not reveal any significant association with any of the haplotypes contained in either block 1 or block 2. Conclusion: These results indicate that there was no evidence for an association of KCNQ1 polymorphisms with T2DM in Tunisian Arabs. [Copyright &y& Elsevier]

Abstract: Aim: To determine whether inpatient diabetes management and education with improved transition to outpatient care (IDMET) improves glycemic control after hospital discharge in patients with uncontrolled type 2 diabetes (T2DM). Methods: Adult inpatients with T2DM and HbA1c>7.5% (58mmol/mol) admitted for reasons other than diabetes to an academic medical center were randomly assigned to either IDMET or usual care (UC). Linear mixed models estimated treatment-dependent differences in the change in HbA1c (measured at 3, 6, and 12 months) from baseline to 1-year follow-up. Results: Thirty-one subjects had mean age 55±12.6 years, with mean HbA1c of 9.7±1.6% (82±18mmol/mol). Mean inpatient glucose was lower in the IDMET than in the UC group (176±66 versus 195±74mg/dl [9.7 versus 10.8mmol/l], P =0.001). In the year after discharge, the average HbA1c reduction was greater in the IDMET group compared with the UC group by 0.6% (SE 0.5%, [7 (SE 5)mmol/mol], P =0.3). Among patients newly discharged on insulin, the average HbA1c reduction was greater in the in the IDMET group than in the UC group by 2.4% (SE 1.0%, [25 (SE 11)mmol/mol], P =0.04). Conclusions: Inpatient diabetes management (IDMET) substantially improved glycemic control 1 year after discharge in patients newly discharged on insulin; patients previously treated with insulin did not benefit.

Abstract: Objective: To analyse first-day-of-life glucose levels in infants of women with gestational diabetes (GDM) and the influence of maternal, gestational and peripartum factors on the development of neonatal hypoglycaemia. Study design: Prospective cohort study including newborns of GDM mothers. Capillary blood glucose (CBG) was measured serially on the first day of life. CBG values were defined as normal (≥2.5mmol/l), mild hypoglycaemia (2.2–2.4mmol/l), moderate hypoglycaemia (1.6–2.1mmol/l) and severe hypoglycaemia (<1.6mmol/l). Results: One hundred and ninety infants were included: 23 (12.1%) presented mild, 20 (10.5%) moderate and only 5 (2.6%) severe hypoglycaemia. Hypoglycaemic infants were more frequently large-for-gestational-age (29.3% vs 11.3%, p =0.003), had lower umbilical cord pH (7.28 vs 7.31, p =0.03) and their mothers had more frequently been hyperglycaemic during labour (18.8% vs 8.5%, p =0.04). In multivariate analysis Pakistani origin (OR: 2.94; 95% CI: 1.14–7.55) and umbilical cord venous pH (OR: 0.04, 95% CI: 0.261–0.99) were significantly and independently associated with hypoglycaemia. Conclusions: Mild and moderate neonatal hypoglycaemias were common although severe episodes were unusual in infants of women with GDM. Hypoglycaemia is mainly influenced by ethnicity and cord blood pH, although maternal peripartum glycaemic control and large-for-gestational-age condition may also play a role.

Abstract: We have developed an electromagnetic microwave cavity sensor based on the resonant frequency shift for real time measurement of the glycemia in pig blood. We could determine the concentration of d-glucose in pig blood in the range of 150–550mg/dl at the resonance frequency near 4.75GHz with a bandwidth of 300MHz. The change in the d-glucose concentration in blood brings microwave reflection coefficient S 11 changes of about 6.26dB and resonance frequency shifts of about 11.25MHz due to the electromagnetic interaction between the cavity resonator and the blood filled plastic tube inserted into the cavity. This proposed system provides a unique approach for real time noninvasive and contactless glucose monitoring. [Copyright &y& Elsevier]

Relationships between exercise, glucose control and diabetes dependent quality of life (DDQoL) are not straightforward. We investigated the DDQoL of 99 persons with type 1 diabetes and linked it to individual amount of weekly physical activity and HbA1c. Physically active lifestyle was not associated with better DDQoL or glucose control. [ABSTRACT FROM AUTHOR]

We found that in obese youth, plasma glucose above 155mg/dl (8.6mmol/l) at 60min of an OGTT, a predictor of type 2 diabetes (T2D) in adults, was present in 12% with normal glucose tolerance and 57% with impaired glucose tolerance. Performance of elevated 1-h glucose in predicting T2D in overweight youngsters should be tested. [ABSTRACT FROM AUTHOR]

Aim: To estimate the prevalence of undiagnosed diabetes, and to identify the relative importance of risk factors for undiagnosed diabetes among Bangladeshi adults.Method: Data from 11, 421 Bangladeshi adults aged 18 years and older available from the most recent nationally representative Bangladesh Demographic and Health Survey 2017-18 were used. Anthropometric measurements and fasting blood glucose samples were taken as part of the survey. Prevalence estimates of undiagnosed diabetes was age-standardised with direct standarisation, and risk factors were identified using multilevel mix-effects Poisson regression models with robust variance.Results: The overall age-standardised prevalence of undiagnosed diabetes was 6.0% (95 %CI, 5.5-6.4%) (men: 6.1%, women: 5.9%). Risk factors associated with undiagnosed diabetes were older age, elevated body mass index (BMI), highest wealth quintile, hypertension, and being male. The top two modifiable risk factors contributing over 50% to undiagnosed diabetes were BMI and wealth quintiles.Conclusion: Undiagnosed diabetes affects a substantial proportion of Bangladeshi adults. Since elevated BMI and the highest wealth quintile are strong risk factors, these offer an opportunity for early detection and screening to reduce undiagnosed diabetes in Bangladesh. In addition, wide-reaching awareness campaigns among the general public, clinicians, and policymakers are needed. [ABSTRACT FROM AUTHOR]

Aims: Considering a surge in the incidence of Diabetes mellitus (DM) across all ethnic groups and lack of any representative data from the tribal communities of Jammu and Kashmir, the present study aimed to assess the prevalence of DM and prediabetes in them.Methods: Subjects were recruited from five districts of Kashmir valley using multistage cluster sampling by probability proportional to size (PPS) technique. Data collection included recording of socio-demographic, medical facts, assessment of anthropometric parameters and biochemical evaluation HbA1c and random blood glucose measurements as per the American Diabetes Association (ADA) criteria were used for diagnosis of DM.Results: A total of 6808 subjects were recruited in this study including 2872 (42%) men and 3936 (58%) women with mean age of 39.60 ± 20.19 years and 35.17 ± 16.70 years, respectively. Around 8.60% subjects were obese, 38.9% were found to be hypertensive, 73% had dyslipidemia and 3.75% had metabolic syndrome. About 1.26% (0.5% males and 0.9% females) had DM and 11.64% had prediabetes based on HbA1c cut offs. Increasing age, body mass index and family history portend significant risk factors while smoking and sedentary lifestyle increased the risk marginally.Conclusions: Although the prevalence of DM among tribals of Kashmir valley is lower than general population, the higher prediabetes to DM ratio may indicate a future trend of increasing DM prevalence in this disadvantageous subpopulation.

Abstract: Post-absorptive glucose lowering (PALG) is observed in individuals with glucose intolerance and in healthy individuals. We report a prevalence of about 23% among healthy Asian Indians. Individuals with PALG are characterized by leaner phenotype, low body fat percentage, increased insulin sensitivity and higher fasting glucose levels. [Copyright &y& Elsevier]

Abstract: We measured fasting plasma glucose (FPG) on a single day in all persons without diabetes history admitted in general wards (N =1922). After age and length of stay adjustment, dextrose infusion was associated with a 3-fold increase (p <0.001) of hospital-related hyperglycemia (FPG≥7mmol/l), highlighting the need to interpret glucose disorders cautiously.
