In most obese people, sugar is blocked from entering fat cells, then blood sugar levels rise leading to insulin resistance & T2. Obesity is assoc with metabolic dysfunction that puts pts at higher risk for DM, stroke & heart disease, but a large percentage of obese people are metabolic-ally healthy. The new study disassociated obesity from its adverse effects. The team tweaked a " glucose transporter " gene in obese mice that serves as a gateway for sugar. Usually, its activity in fat cells drops with obesity. When the glucose transporter levels was increased in obese mice, it allowed more sugar into their fat cells which protected them from DM. Conversely, normal weight mice missing that gene developed DM symptoms. Sugar in fat cells triggered a response from the ChREBP gene that regulated insulin sensitivity throughout the body. online edition of the journal Nature. 3.%% DiabCare.2012;35(2) Efficacy/safety of exenatide once weekly (EQW) vs metformin, pioglitazone, & sitagliptin used as monotherapy in drug-naive pts with T2 Random-double-blind study;26wks.

Medscape: Would you describe early initiation & intensification of IT. Dr.M It means utilizing the guidelines from the ADA & using insulin sooner rather than later. All too often, doctors...advise pts to take oral agent #1, then #2, then oral agent #3, & then say, " Wow, I guess it's time to start insulin. " M: Why is this topic important? Dr.M We have got a failing grade on the number of pts that have their DM in control. In a lot of patients, the hemoglobin A1c is above 7%-complications happen at a more prevalent rate [at that level]..we have some fantastic insulins now that we didn't have just a few years ago. We can now match pts' physiologic problems with the insulins. M: What are some common misperceptions abt IT? ..pts think the needle is really, long or that they will be perceived as having bad control of their DM...I always say, " Let's talk about insulin pens.

While the technique reduces the risk of visual loss, it may not be quite as good at improving visual acuity. That's why clinicians have been using VEGF inhibitors off-label for this condition. The 2 most commonly used are ranibizumab (Lucentis) which is approved for age-related macular degeneration & avastin-long approved for various cancer indications. Both drugs are made by Genentech, but ranibizumab injections can run $1,950 each while bevacizumab costs only $50 per shot.

Recent guidelines by AmerCollege Physicians (ACP) state that metformin should be used as a first-line agent to treat DM when diet & EX are insufficient There was an assoc risk for severe hypoglycemia with SUs which exceeds the risk with metformin The combo of metformin plus SUs is assoc with 6x more risk for hypo The ACP statements suggest that, for agents other than metformin, SUs should be considered 3rd or 4th line agents for T2. Some DM agents, seem to preserve beta-cell function, but the action of SUs " burns out " beta cells. .A significant benefit with the use of sulfony-lureas is that they are very inexpensive - the only generic anti-DM drug available. Guidelines that recommend SUs as initial or second- line Rx tend to be much simpler & easier to follow., Some clinicians may prefer " the devil they know " rather than newer drugs that seem to carry uncertainties. More to come, later... M.L. Mintz, MD CA 9.%% MNT 4/9 Enzyme In Saliva Helps Regulate Blood Glucose [bG] BG levels after starch ingestion are influenced by differences in salivary amylase [sA]an enzyme that breaks down dietary starches. Higher SA activity is related to lower blood glucose. Findings show a significant metabolic role for salivary amylase in starch digestion. Other implications relate to calculating the glycemic index of starch- rich foods & ultimately the risk of developing DM. 2 pts may have very different glycemic responses to the same starchy food, depending on their SA levels. Those with high SA are better adapted to eat starches, because they rapidly digest the starch while maintaining balanced BG levels. Those with low SA levels need to take their amylase levels into account when paying attention to the glycemic index of foods they are eating. Starch from wheat, corn, potatoes, & other grains makes up to 60% of calories in the US. Amylase enzymes secreted in saliva help break down starches into simpler sugars that can be absorbed into the bloodstream thus influencing BG levels. [48 healthy adult] divided into high amylase(HA) & low (LA). Each pt drank a corn starch solution. Afterwards, pts in the HA grp had lower BG levels vs those in the LA grp. This appears to be related to an early release of insulin by the HA pts. Pts with higher levels of salivary amylase are able to maintain more stable BG levels when eating starch. This might lessen their risk for insulin resistance & non-insulin dependent DM. Future study focus will involve identifying the neuro-endocrine mechanisms that connect starch breakdown in the mouth with insulin release. 10.%% M 4/12 DM Linked to Phthalates Phthalates, [P] which are found in common plastics, cosmetics, pharmaceuticals & medical devices, have been associated with the development of DM among seniors in Sweden. 3 P metabolites were associated with a 25-30% increase in the risk for DM. [1016 pt;70yrs +] 4 of 10 metabolites were detectable in blood serum of at least 96% of pts with DM. 4 P metabo-lites are commonly used in personal care fragrances (includes- monoethyl P(MEP). monoisobutyl P(MiBP). MEP & MiBP were significantly related to DM prevalence. The metabolites are related to either poor insulin secretion or insulin resistance P metabolites are known to affect glucose stability in humans. Further studies are needed that show similar associations. However, for seniors at normal levels of exposure to chemicals.. this study showed that several phthalate metabolites are related to DM prevalence, as well as to markers of insulin secretion & resistance. pub 4/2012 DiabCare. 11.%% M 4/10 Infant & Toddler T1DM Complications After 20 Years' Duration S. Salardi, MD; et al:Diabetes Care2012;35(4): To compare the effect of the prepubertal duration of DM on the occurrence of complications in 2 groups of patients after the same number of years of the disease. [105 pts aged 16–40.3 years; 53 prepubertal at diagnosis (aged 0–3);52 were pubertal Results: prevalence of diabetic retinopathy (DR) was higher in pubertal than in prepubertal pts Conclusions: If diabetes is diagnosed in infants or toddlers and the prepubertal duration of DM is very long, the patients seem to be protected against DR. This protection disappears if lifetime metabolic control is bad. Instead, when onset is at puberty, the DR risk is higher & less dependent on metabolic control & may be influenced by age- related factors, such as BP. 12.%%MA 4/6 Postprandial Administration of Intranasal Insulin Intensifies Satiety & Reduces Intake of Palatable Snacks in Women Diab 2012;61(4): Abstract - The role of brain insulin signaling in the control of food intake in humans has not been thoroughly defined. We hypothesized that the hormone contributes to the postprandial [PP] regulation of appetite for palatable food..Two groups of subjects were intranasally given 160 IU insulin or placebo after lunch. 2hr later con-sumption of cookies of varying palatability was measured. In control study,the effects of intranasal insulin administered to fasting female subjects were assessed. Compared with placebo, insulin adm in the PP but not in the fasting state decreased appetite as well as intake & rated palatability of chocolate chip cookies. In both experiments, intranasal insulin induced a slight decrease in plasma glucose but did not affect serum insulin concentrations. Data indicate that brain insulin acts as a relevant satiety signal during the PP period, in particular reducing the intake of highly palatable food, & impacts peripheral glucose homeostasis. PP intranasal insulin adm might be useful in curtailing overcon-sumption of snacks.. 13.%% M 4/12 Higher HbA1c Levels Predict Better Outcomes in Advanced Heart Failure [HF] With Diabetes — Patients with advanced HF who were also diabetic had better 2yr survival if their baseline glycated hemoglobin (HbA1c) levels were >[greater than] 7.3% in a new study. The retrospective cohort study pub3/27/12 online in the AmerJ Cardiology. " We're finding that in HF plus DM, higher HbA1C levels are associated not with worse outcomes, but with better outcomes, " lead investigator Dr T. Horwich(UCLA)said. This suggests that for pts with both diseases, " .. aiming for a midrange of 7.2 to 8.2% may be very reasonable ..in someone with advanced HF who may be having difficulties with hypoglycemia or other adverse effects of DM meds, less stringent glycemic control (HbA1C <8%) may be acceptable,” On the other hand, " if patients are tolerating the meds without difficulties, current glycemic guidelines should continue to be followed as we await further info from prospective clinical trials. " 14.%% PostgradMed J2012;88 Diabetes-induced Osteoarthritis Data support the hypothesis that DM could be an independent risk factor for OA. If confirmed, this new paradigm will have a dramatic impact on prevention of OA initiation & progression..Diabetes was first considered as a non-inflammatory disease. However, we now know hyperglycaemia can trigger a low-grade systemic inflamm. which would explain the increased risk of CV events seen in pts with DM. Low-grade systemic inflammation is associated with cartilage loss. ..an independent hyperglycaemia-induced systemic inflam may also have an impact on the progression of OA. ..Finally, the neurotoxicity of hyperglycaemia leads to a neuromuscular deficiency, which will also worsen OA by destabilising the joint. 15.%% MPD Diabetes Diagnosis and Management 2011 Web cast for health care providers- The Endocrine Society http://www.softconference.com/endocrine/generic.asp?ID=8067 16.%% MA 4/11 Bevacizumab Beats Laser Therapy in Macular Edema Trial A 2-year randomized controlled trial suggests that bevacizumab (Avastin) is more effective than macular laser therapy in pts with DME. R Rajendram, Moorfields & team report " Many people are using bevacizumab, even though this is the only study out there that shows any benefits, " said Dr. Wayne State U " I think it's an important study, though it's not yet definitive because there were only 80pts & you would usually like to have hundreds. " Macular laser therapy had been the mainstay of treatment for clinically significant DME since the 1980s. The procedure reduces the risk for moderate visual loss, but visual acuity improves in less than 3% of pts. Preliminary evidence has emerged that intravitreal injections of antivascular endothelial growth factor (anti-VEGF) drugs are more effective..patients randomly assigned to receive either bevacizumab or laser. Those receiving avastin had an injection at baseline, 6 & 12 wks, were reviewed at 18 wks & every 6 wks to wk 102 for the need of more injections. If the central macular thickness was greater than 270 ?m at 18 wks the team continued injections until the pts had stable macular thickness. Overall, the patients receiving bevacizumab fared better than the pts receiving laser. The mean ETDRS best-corrected visual acuity at 24 m in the Bev group was 64.4 letters(Snellen equiv 20/50) vs In the laser group 54.8 letters(Snell 20/80). The pts on Bev gained a mean of 8.6 letters, while laser grp lost a mean of 0.5. The pts on bevacizumab had 27 adverse events, 22 related to the injections. A few pts in both groups experienced transient vision loss. 3 patients in the laser grp had serious ocular adverse events. There were no cases of endophthalmitis, intraocular inflammation, or retinal detachment in the bevacizumab group. " This investigator-initiated single-center study provides evidence for the longer-term use of bevacizumab, " authors write.

We reviewed 1- & 2-year clinical trial findings for ranibizumab [lucentis] used as treatment for DME... For DME with centre involvement & assoc vision loss due, monthly ranibizumab with Rx interruption & re-initiation based on VA stability is recommended. Laser therapy based on ETDRS guidelines is recommended for other forms of clinically significant DME without centre involvement or when no vision loss has occurred.. Since these recommendations are based on randomised controlled trials of 1–2 years duration, guidance may need updating as long-term ranibizumab data become available and as additional therapeutic agents are assessed in clinical trials. 18.%%Eye 2012)26, Distribution, reabsorption, and complications of preretinal blood under silicone oil after vitrectomy for severe prolifer ative diabetic retinopathy [DR] 44 pts;3-yr period.

The human body has a chronological age & biological age. Biological age is represented by the DNA sequence at the end of each chromosome, like the plastic tips on shoelaces (telomeres). The telomeres get shorter each time a cell divides. Short telomeres reflect accelerated aging. Many recently discovered genes that can be manipulated to slow the aging process are involved in the control of metabolism. Metabolic syndrome, is a precursor of metabolic disorders like T2 & CV disease, which have been shown to be a sign of premature aging. DM is a state of accelerated aging. While telomere shortening is associated with T2, there is a lack of studies that explore the relationship among telomere length, oxidative stress, mitochondrial DNA content, & the levels of adiponectin (a protein produced by fat cells which play a role in the development of obesity). Researchers reason that the susceptibility to develop T2 & cardio-vascular diseases could be explained by studying these emerging biomarkers. Unlike chronological aging, accelerated aging can be reversed. With maintenance of appropriate mitochondrial function & telomere length by pharmacological means or lifestyle modification there will be potential for T2DM & associated vascular disorders.

J Osório - C-peptide, a hallmark of ß-cell function, can be detected in the serum of pts with T1 >30 yrs after disease onset, report researchers from Harvard Med School. C-peptide [C-P] is a chain of proteins that is spun off when the beta cell makes insulin. A precursor molecule, pro-insulin is split into insulin & C-P. For every molecule of insulin produced, your beta cells also produce a molecule of C-peptide. C-P is removed from the bloodstream by your kidneys while insulin is removed by the liver. A C-peptide test tells you whether or not you are making C-P. If there is no C-peptide in a blood sample, your beta cells are not making any insulin. A very low C-peptide results in the diagnosis of severe T1DM. When doing C-peptide tests it is important to know whether the C-P test is taken fasting/not fasting & what the blood glucose level was when the sample was taken. A high fasting BS with a high C-peptide shows T2 caused by insulin resistance. In contrast, a normal C-P value taken at the same time as a high fasting glucose suggests T2 where failing beta cells rather than insulin resistance is the primary reason for raising blood sugar. Unfortunately, there is no standard way a lab measures C-peptide If you sent the same sample to a different lab, you could get a very different result. Here's what your C-peptide can tell you: 1. If your C-P is significantly below the normal fasting range your beta cells are likely to be dead or dying. A very low C-peptide value is a good way of diagnosing T1DM (autoimmune) rather than T2DM. Some insurers require a C-peptide test result below .5 nanograms/ml before they will cover the costs of an insulin pump. 2. If your fasting C-P level is high, it is very likely that you will be able to control your BS by cutting way down on the amount of carbohydrate you eat. It also means that you should first try strategies that lower insulin resistance before trying drugs that stimulate more insulin. Exercise may also be very helpful, as many find, to reduce insulin resistance. Research suggests C-peptide rather than being only an inert by-product of insulin synthesis, is rather important for preventing DM complications. If it turns out that C-P is able to prevent complications, those who have secretory defects that respond to beta cell stimulation may have to reconsider whether or not to stimulate their beta cells with drugs like sulfony-lureas or whether to supplement with injected insulin that does not contain C-peptide.

Hamann, et al; DM adversely affects the skeleton & is assoc with an increased risk of osteoporosis & fragility fractures. The mechanisms underlying low bone strength are not fully understood but could include impaired accrual of peak bone mass & DM complications, such as nephropathy. T1 affects the skeleton more severely than T2, probably due to lack of the bone anabolic actions of insulin & other pancreatic hormones. Bone mass can remain high in T2 but it does not protect against fracture, as bone quality is impaired The class of oral anti-DM meds-glitazones [Actos, Avandia] can promote bone loss & osteoporotic fx in post-menopausal women & should be avoided if O is diagnosed. A physically active, healthy lifestyle & prevention of DM complications, along with calcium & VitD, is the mainstay of therapy for O in pts with T1 or T2. Assessment of BMD [bone mineral density] & other risk can help design tailored Rx plans.

C Mathieu & team have attempted to circumvent this response by taking advantage of the fact that the immune system accepts foreign gut bacteria. They engineered gut bacteria which make a form of insulin.. these special bacteria increased the frequency of cured mice when compared to traditional methods, with seemingly no undesirable effects.
