IntroductionWe examined years of potential life lost (YPLL) associated with pre-diabetes as compared with either normoglycemia or diabetes, using data of the Israel cohort of Glucose intolerance, Obesity and Hypertension 40-year follow-up.Research design and methodsMen and women (N=2844, mean age 52.0±8.2 years) who underwent oral glucose tolerance test and anthropometric measurements, during 1976–1982, were followed for mortality until May 2019. Multiple imputation procedures for missing mortality dates and multivariable regression mixed models were applied.ResultsAt baseline, 35.8%, 48.8% and 15.4% individuals were found with normoglycemia, pre-diabetes, and diabetes, respectively. The average difference in YPLL associated with pre-diabetes as compared with normoglycemia was 4.3 years (95% CI 3.3 to 5.2; p<0.001). YPLL were 1 year higher in women with pre-diabetes than in men with pre-diabetes. These differences persisted mainly in individuals younger than 60 years, and those with body mass index (BMI) <25 kg/m2, at baseline. Adjusting for age, sex, country of origin, smoking status, BMI, and blood pressure, the average difference in YPLL associated with pre-diabetes as compared with normoglycemia was 2.0 years (95% CI 1.2 to 2.8; p<0.001). Significant reductions of 5.9 years (95% CI 4.8 to 7.0) on average were observed for diabetes as compared with pre-diabetes and 7.9 years (95% CI 6.7 to 9.1) as compared with individuals with normoglycemia.ConclusionsThis study reveals that life expectancy of middle-aged individuals with pre-diabetes is shorter than of normoglycemic ones. These findings are especially relevant in view of the rising worldwide prevalence of pre-diabetes within younger age groups and underscore the crucial importance of interventions by either lifestyle modification or drug therapy capable of delaying progression from pre-diabetes to diabetes to reduce the YPLL in this high-risk group.

BackgroundWomen with gestational diabetes (GDM) have an elevated risk of developing type 2 diabetes (T2DM). NICE Guidance recommends women who develop GDM are screened 6 weeks post-partum and annually thereafter.AimTo evaluate conformity to guidance of screening in women with GDM by 6-week post-partum fasting plasma glucose (FPG) and annual FPG and determine time between delivery and development of T2DM.MethodRecords at a tertiary referral centre were used to identify women (n = 54) diagnosed with GDM by antenatal oral glucose tolerance test between July 1999 and January 2007. Data from laboratory records were used to collect investigations of glycaemic status during the follow-up period (median follow-up 12.4 years, range 9.5–17.1 years).ResultsOf 252 women, 102 (40.2%) did not have a FPG at 6 weeks (+/−2 weeks). Of these, median time to first test was 1.2 years (range 0.04–10.8 years), with only 43.1% followed-up within 1 year. In those who had a 6-week FPG, 17 (11.3%) women had no further tests. A total of 84 (33% of those with gestational diabetes in the index pregnancy) women were diagnosed with T2DM; median time from delivery to diagnosis was 5.2 years (range 0.35–15.95). We found the only significant factor for a follow-up test at 1-year post-partum was the use of insulin.ConclusionOur data suggest an alternative approach is needed for monitoring women with a history of GDM. This needs to be appropriate for a generally healthy group in which traditional screening mechanisms may not be adequate or sufficient.

Skeletal Fragility

Increased risks of skeletal fractures are common in patients with impaired glucose handling and type 2 diabetes mellitus (T2DM). The pathogenesis of skeletal fragility in these patients remains ill-defined as patients present with normal to high bone mineral density. With increasing cases of glucose intolerance and T2DM it is imperative that we develop an accurate rodent model for further investigation. We hypothesized that a high fat diet (60%) administered to developing male C57BL/6J mice that had not reached skeletal maturity would over represent bone microarchitectural implications, and that skeletally mature mice would better represent adult-onset glucose intolerance and the pre-diabetes phenotype. Two groups of developing (8 week) and mature (12 week) male C57BL/6J mice were placed onto either a normal chow (NC) or high fat diet (HFD) for 10 weeks. Oral glucose tolerance tests were performed throughout the study period. Long bones were excised and analysed for ex vivo biomechanical testing, micro-computed tomography, 2D histomorphometry and gene/protein expression analyses. The HFD increased fasting blood glucose and significantly reduced glucose tolerance in both age groups by week 7 of the diets. The HFD reduced biomechanical strength, both cortical and trabecular indices in the developing mice, but only affected cortical outcomes in the mature mice. Similar results were reflected in the 2D histomorphometry. Tibial gene expression revealed decreased bone formation in the HFD mice of both age groups, i.e., decreased osteocalcin expression and increased sclerostin RNA expression. In the mature mice only, while the HFD led to a non-significant reduction in runt-related transcription factor 2 (Runx2) RNA expression, this decrease became significant at the protein level in the femora. Our mature HFD mouse model more accurately represents late-onset impaired glucose tolerance/pre-T2DM cases in humans and can be used to uncover potential insights into reduced bone formation as a mechanism of skeletal fragility in these patients.

Abstract Aims and Methods The declining ability to control blood glucose with advancement of age is an important health risk factor and may lead to insulin resistance, type-2-diabetes and Alzheimer’s disease. Adenovirus 36(Ad36) improves glycemic control independent of insulin signaling(insulin sparing effect) as evidenced by cell, animal and observational human studies. This property of Ad36 may be useful in correcting aging-related glucose intolerance and related health conditions. Therefore, we determined the effect of Ad36 on glycemic control in older mice, to identify the age group that best responds to Ad36. Six, 12 or 20-month old C57Bl/6 mice on chow diet were each divided into weight-matched groups(mock-infected or Ad36-infected). Body weight was recorded weekly post infection (p.i.) and fasting glucose measured(week 0, 4, 8 and 20 p.i.). Blood glucose and serum insulin were measured during glucose tolerance test(week 0 and 16 p.i.). At week 20 p.i., animals were sacrificed, blood and tissues collected. Results Mice from all age groups showed improvement in glucose clearance post Ad36 infection, but a more profound effect was observed in 6-month old mice compared with mock-infected mice. Under fed conditions though there was no difference in blood glucose at 20 wk p.i., interestingly, Ad36 reduced serum insulin in age groups old mice, compared with control mice. Conclusions These findings suggest Ad36 infected animals improve glycemic control and clear post-prandial gluco00000se increase without increasing insulin secretion in an insulin sparing manner. These beneficial effects provide strong evidence for developing Ad36-based approaches as a novel tool to attenuate age associated glucose intolerance.

We aimed to clarify how the trajectories of 1-hour postload plasma glucose (PG) and 2-hour PG were different in the development of type 2 diabetes. Using data of repeated health checkups in Japanese workers from April 2006 to March 2016, longitudinal changes of fasting, 1-hour, and 2-hour PG on the oral glucose tolerance test were analyzed with a linear mixed effects model. Of the 1464 nondiabetic subjects at baseline, 112 subjects progressed to type 2 diabetes during the observation period (progressors). In progressors, 1-hour PG and 2-hour PG showed gradual increases with slopes of 1.33 ± 0.2 and 0.58 ± 0.2 mg/dL/year, respectively, followed by a steep increase by which they attained diabetes. Until immediately before the diabetes transition, age- and sex-adjusted mean level of 2-hour PG was 149 ± 2.7 mg/dL, 34 ± 2.7 (30%) higher compared to nonprogressors, while that of 1-hour PG was 206 ± 4.1 mg/dL, 60 ± 4.3 mg/dL (41%) higher compared to nonprogressors. In conclusion, diabetes transition was preceded by a mild elevation of 2-hour PG for several years or more. The elevation in 1-hour PG was larger than that of 2-hour PG until immediately before the transition to diabetes.

ObjectiveAmong individuals at high risk for diabetes identified through a population survey, we performed an intervention study with basic lifestyle advice aiming to prevent diabetes.Research design and methodsAmong 50 806 participants in the HUNT3 Survey (2006–2008), 5297 individuals with Finnish Diabetes Risc Score (FINDRISC ≥15 were invited to an oral glucose tolerance test (OGTT) and an education session with lifestyle advice, and 2634 (49.7%) attended. Among them, 2380 people without diabetes were included in the prevention study with repeated examinations and education sessions after 6, 12, and 24 months. We examined participation, diabetes incidence, glycemia, and adiposity during follow-up.ResultsOf 2380 participants, 1212 (50.9%) participated in ≥3 of the four examinations. Diabetes was detected in 3.5%, 3.1%, and 4.0% of individuals at the 6-month, 12-month, and 24-month examinations, respectively, indicating a 10.3% 2-year diabetes incidence. Mean (95% CI) increases from baseline to 2-year follow-up were 0.30 (0.29 to 0.32) percentage points (3.3 (3.2 to 3.5) mmol/mol) for Hemoglobin A1c, 0.13 (0.10 to 0.16) mmol/L for fasting serum-glucose, 0.46 (0.36 to 0.56) mmol/L for 2-hour OGTT s-glucose, 0.30 (0.19 to 0.40) kg/m2 forbody mass index (BMI) (all p<0.001) and −0.5 (-0.9 to −0.2) cm for waist circumference (p=0.004), with broadly similar estimates by baseline age, sex, education, depressive symptoms, BMI, physical activity, and family history of diabetes. Only 206 (8.7%) participants had evidence of >5% weight loss during follow-up; their fasting and 2-hour s-glucose did not increase, and HbA1c increased less than in other participants.ConclusionBasic lifestyle advice given to high-risk individuals during three group sessions with 6-month intervals was not effective in reducing 2-year diabetes risk.

Purpose A significant proportion of adults surviving childhood cancer are smokers. Although these estimated rates of smoking are slightly lower than those in the US population, they remain alarmingly high for this high-risk group. The purpose of this study was to examine the predictive validity of adolescent self-reported smoking intentions for later smoking among childhood cancer survivors. Patients and Methods Baseline tobacco intentions were collected from 119 nonsmoking cancer survivors, age 10 to 18 years, who participated in a tobacco-based clinical trial during the late 1990s. Follow-up smoking status was systematically collected annually up to 10 years postintervention (median follow-up, 6.0 years; interquartile range, 3.0 to 6.9 years) as part of clinical survivorship care. Results Twenty-seven participants (22.7%) subsequently initiated tobacco use within 5 years of study enrollment. The 5-year cumulative incidence was 29.8% ± 6.0% for those who were susceptible to smoking compared with 12.8% ± 5.4% for those who were committed never smokers (P = .022). Past use (P < .001) and having friends who smoked (P = .038) were also associated (univariate model) with tobacco initiation, and there was a trend for an association for older adolescents (P = .073). Every unit increase on the intentions scale was associated with a 17% increase in the risk for tobacco initiation (P = .002) after adjusting for age group and past tobacco use in a multivariable model. Conclusion Because early intentions to smoke are predictive of later tobacco use, survivors as young as 10 years of age who waver in their commitment to remain tobacco abstinent should be targeted for tobacco prevention interventions.
