Do Older Adults Aged 60–75 Years Benefit From Diabetes Behavioral Interventions?
OBJECTIVE In this secondary analysis, we examined whether older adults with diabetes (aged 60–75 years) could benefit from self-management interventions compared with younger adults. Seventy-one community-dwelling older adults and 151 younger adults were randomized to attend a structured behavioral group, an attention control group, or one-to-one education. RESEARCH DESIGN AND METHODS We measured A1C, self-care (3-day pedometer readings, blood glucose checks, and frequency of self-care), and psychosocial factors (quality of life, diabetes distress, frustration with self-care, depression, self-efficacy, and coping styles) at baseline and 3, 6, and 12 months postintervention. RESULTS Both older (age 67 ± 5 years, A1C 8.7 ± 0.8%, duration 20 ± 12 years, 30% type 1 diabetes, 83% white, 41% female) and younger (age 47 ± 9 years, A1C 9.2 ± 1.2%, 18 ± 12 years with diabetes, 59% type 1 diabetes, 82% white, 55% female) adults had improved A1C equally over time. Importantly, older and younger adults in the group conditions improved more and maintained improvements at 12 months (older structured behavioral group change in A1C −0.72 ± 1.4%, older control group −0.65 ± 0.9%, younger behavioral group −0.55 ± 1.2%, younger control group −0.43 ± 1.7%). Furthermore, frequency of self-care, glucose checks, depressive symptoms, quality of life, distress, frustration with self-care, self-efficacy, and emotional coping improved in older and younger participants at follow-up. CONCLUSIONS The findings suggest that, compared with younger adults, older adults receive equal glycemic benefit from participating in self-management interventions. Moreover, older adults showed the greatest glycemic improvement in the two group conditions. Clinicians can safely recommend group diabetes interventions to community-dwelling older adults with poor glycemic control

Statin-induced diabetes: incidence, mechanisms, and implications
Persuasive data from many randomized controlled trials and large, long-term observational studies indicate a modestly increased risk for the emergence of new diabetes after statin initiation. Several meta-analyses of many statin trials as well as longitudinal population-based studies suggest that the risk factors for diabetes in statin-treated persons include underlying risk for diabetes at baseline (specifically features of metabolic syndrome), the intensity of statin therapy, certain genetic traits independent of diabetes risk, and adherence to lifestyle factors. Limited data suggest statins modestly worsen hyperglycemia and A1c levels in those with pre-existing diabetes or glucose intolerance. The precise mechanism(s) of diabetogenesis with statin therapy are unclear, but impaired insulin sensitivity and compromised β cell function via enhanced intracellular cholesterol uptake due to inhibition of intracellular cholesterol synthesis by statins, as well as other mechanisms, may be involved. Furthermore, while statins are known to have anti-inflammatory effects, it is hypothesized that, under dysmetabolic conditions, they might have pro-inflammatory effects via induction of certain inflammasomes. This concept requires further elucidation in the human. Finally, it is clear that the risk–benefit ratio for cardiovascular disease events is strongly in favor of statin therapy in those at risk, despite the emergence of new diabetes. Adherence to lifestyle regimen is critical in the prevention of new diabetes on statins
Height-Weight Indices and Blood Lipid Levels in Normal Controls and Offspring of Conjugal Diabetics
The purpose of this study was to investigate body size and body mass relative to total fasting cholesterol, triglyceride, high density and low density lipoprotein cholesterol levels and ratios in normal controls and offspring of conjugal Type II diabetics. Height, weight, percent ideal weight, and height/weight, ponderal, body mass and F-index ratios were used in the assessment of relative body size and body mass. Correlative examination of these height-weight measures and ratios relative to blood lipid analysis demonstrated that significant relationship patterns were more common for the offspring than for the control group.An analysis of variance study utilizing ponderal and body mass indices as representative and respective measures of body size and body mass in regard to the blood lipids, corroborated the correlation results. In reference to the ponderal and body mass indices of the offspring group, many mean significant differences were found in favor of the lean and underweight in comparison to the average and desirable weight, and stout and overweight subgroups relative to all of the blood lipid levels and ratios. In contrast, few control gtoup mean significant differences between the subgroups were found. Age may also have contributed to the results obtained, since the stout and overweight subgroups were generally older than their leaner and lighter subgroup counterparts. The overall results of this study indicate that increased body size and body mass are related to increased blood lipid levels and ratios, especially in the offspring group with a high genetic risk of developing diabetes and atherosclerosis

Alanine-induced amino acid interrelationships
Six normal subjects received 10 g of alanine both orally and as a 60-min intravenous infusion. In both studies blood samples for hormones and substrates were obtained every thirty minutes for

. Significant increases in whole blood levels of threonine, serine, glutamine, proline, glycine, and α-amino-n-butyric acid were found, which were mainly due to increases of these amino acids in the plasma compartment. In contrast, whole blood levels of leucine, valine, and isoleucine declined, mainly due to decreases in the cell compartment. Plasma glucagon levels increased in both studies while insulin levels rose significantly only during the oral study. Plasma free fatty acids and blood glycerol levels declined while lactate and pyruvate increased. Glucose concentration did not change during both tests.
These data suggest that the administration of large quantities of alanine is capable of inducing significant alterations in levels of other amino acids and substrates as well as changing hormone levels
The Role of Bile Acid Sequestrants in the Management of Type 2 Diabetes Mellitus
The prevalence of type 2 diabetes (T2DM) and cardiovascular disease (CVD) continues to escalate globally. There is now abundant clinical trial evidence that the optimal treatment of CVD risk factors, with lifestyle changes aimed at weight loss in most patients, and pharmacologic management of dyslipidemia and hyperglycemia, can help mitigate the CVD burden. Yet more than 50% of patients are still not achieving glycosylated hemoglobin (HbA1c) and low-density lipoprotein cholesterol (LDL-C) goals. Over the past 15 years, many novel and emerging drugs have made it possible to achieve optimal glycemic control, generally in combination therapy, without untoward effects of weight gain, hypoglycemia, and other adverse effects with traditional agents. Although the long-term efficacy and safety of some of the newer classes of agents are yet to be determined, bile acid sequestrants represent a unique long-standing class of agents. These drugs have the dual efficacy in glycemic control and LDL-C reduction, and an established record of long-term safety. Colesevelam HCl is the only drug approved for this dual indication and is an adjunct in the treatment of both hyperglycemia and hypercholesterolemia that frequently co-exist in adults with T2DM
