    "Psychological insulin resistance" (PIR) is an obstacle to insulin treatment in type 2 diabetes, and patients' expectations regarding alternative ways of insulin delivery are poorly understood. PIR and beliefs regarding treatment alternatives were analyzed in patients with type 2 diabetes (n=532; mean glycated hemoglobin, 68±12 mmol/mol [8.34±1.5%]) comparing oral antidiabetes treatment, subcutaneous insulin injections, or inhaled insulin. Questionnaires were used to assess barriers to insulin treatment (BIT), generic and diabetes-specific quality of life (Short Form 36 and Problem Areas in Diabetes, German version), diabetes knowledge, locus of control (Questionnaire for the Assessment of Diabetes-Specific Locus of Control, in German), coping styles (Freiburg Questionnaire of Illness Coping, 15-Items Short Form), self-esteem (Rosenberg Self-Esteem Scale, German version), and mental disorders (Patient Health Questionnaire, German version). Patients discussed treatment optimization options with a physician and were asked to make a choice about future diabetes therapy options in a two-step treatment choice scenario. Step 1 included oral antidiabetes drugs or subcutaneous insulin injection (SCI). Step 2 included an additional treatment alternative of inhaled insulin (INH). Subgroups were analyzed according to their treatment choice. Most patients perceived their own diabetes-related behavior as active, problem-focused, internally controlled, and oriented toward their doctors' recommendations, although their diabetes knowledge was limited. In Step 1, rejection of the recommended insulin was 82%, and in Step 2, it was 57%. Fear of hypoglycemia was the most important barrier to insulin treatment. Patients choosing INH (versus SCI) scored higher regarding fear of injection, expected hardship from insulin therapy, and BIT-Sumscore. The acceptance of insulin is very low in type 2 diabetes patients. The option to inhale insulin increases the acceptability for some but

    Insulin therapy is a therapeutic cornerstone in patients with type 1 diabetes and also in numerous patients with type 2 diabetes especially with longer history of diabetes. The initiation of insulin therapy in type 2 diabetes patients is often delayed which is at least partially due to suboptimal pharmacokinetic characteristics of available insulins. The development of novel insulins with more favorable characteristics than those of current insulins is therefore still ongoing. The aim of this paper is to review current knowledge of novel insulins that have been recently introduced to the market or are getting close to routine clinical use. We will also focus on the perspectives of insulin therapy in the long-term run including the alternative routes of insulin administration beyond its classical subcutaneous injection treatment.Key words: alternative routes of insulin administration - diabetes mellitus - hypoglycemia - insulin - insulin analogues.

    To improve insulin therapy, new insulin analogues have been developed. Two fast-acting analogues with a more rapid onset of effect and a shorter duration of action combined with a low day-to-day variation in absorption rate are now available. Despite this favourable time-action profile most studies....... This is probably the main explanation for the absence of improvement in overall glycaemic control when compared with regular human insulin. A tendency to a reduction in hypoglycaemic events during treatment with fast-acting analogues has been observed in most studies. Recent studies have indicated that NPH insulin...... administered several times daily at mealtimes can improve glycaemic control without increasing the risk of hypoglycaemia. The fast-acting analogues are now also available as insulin mixed with NPH. Insulin glargine is a new long-acting insulin which is soluble and precipitates after injection, resulting...

    Insulin resistance and endogenous hyperinsulinemia are associated with blood hypertension. The aim of this analysis is to estimate the prevalence of blood hypertension one year after insulin treatment in type 2 diabetic patients. and methods: This is a retrospective clinical study of 178 type 2 diabetic patients (57 men and 121 women) insulin treated since at least one year. Mean age is 62 +/- 10 years and mean duration of diabetes is ten years. All patients had a clinical and biological control before treatment with insulin and at least three controls during the first year of insulin treatment (anthropometric measurements, blood pressure, fasting plasma glucose, HbA1C). WHO definition of hypertension is used (blood pressure >or=140 / 90 mmHg). At baseline, 48% of patients have hypertension. After insulin treatment, the prevalence of hypertension significantly increase to 53% (94 / 178) three months later (p=0.008), to 54.5% (98 / 178) six months later (p=0.001) and to 55.6% (99 / 178) twelve months later. This increase in hypertension frequency is associated with a significant weight gain and a better blood glucose control. Insulin therapy may contribute to the development of blood hypertension. It promotes renal sodium retention and increases sympathetic nervous system activity. In the UKPDS intensive blood glucose control with insulin is not associated with an increase of macro vascular complications. These observational data suggest the need for further study of the relationship between exogenous insulin and hypertension.

  5. Stress Hyperglycemia, Insulin Treatment, and Innate Immune Cells

    Full Text Available Hyperglycemia (HG and insulin resistance are the hallmarks of a profoundly altered metabolism in critical illness resulting from the release of cortisol, catecholamines, and cytokines, as well as glucagon and growth hormone. Recent studies have proposed a fundamental role of the immune system towards the development of insulin resistance in traumatic patients. A comprehensive review of published literatures on the effects of hyperglycemia and insulin on innate immunity in critical illness was conducted. This review explored the interaction between the innate immune system and trauma-induced hypermetabolism, while providing greater insight into unraveling the relationship between innate immune cells and hyperglycemia. Critical illness substantially disturbs glucose metabolism resulting in a state of hyperglycemia. Alterations in glucose and insulin regulation affect the immune function of cellular components comprising the innate immunity system. Innate immune system dysfunction via hyperglycemia is associated with a higher morbidity and mortality in critical illness. Along with others, we hypothesize that reduction in morbidity and mortality observed in patients receiving insulin treatment is partially due to its effect on the attenuation of the immune response. However, there still remains substantial controversy regarding moderate versus intensive insulin treatment. Future studies need to determine the integrated effects of HG and insulin on the regulation of innate immunity in order to provide more effective insulin treatment regimen for these patients.

    Inflammation contributes to the pathogenesis of diabetes. A reciprocal relationship exists between diabetes and chronic periodontitis. This report describes the effects of an acute focal dental inflammation and subsequent endodontic treatment on the required insulin dosage of a 70-year-old man who had moderately controlled diabetes. Following an exacerbation of a combined endodontic-periodontic (endo-perio) lesion of tooth #3, the patient noticed a sudden increase in his insulin demand. After 3 weeks, the required dosage was approximately 100% greater. In association with hyperglycemic incidents, he reported a prickling sensation in this tooth. The radiograph showed circular bone loss around the tooth. Just 1 day after the root-canal preparation, the insulin need decreased to approximately 50% of that required prior to treatment. Subsequently, an incision and systemic antibiotics were necessary because of the formation of a periodontal abscess. The insulin demand remained low despite this complication. Forty days after endodontic treatment, the insulin dosage was at a level comparable to that taken 4 weeks before the root-canal preparation. This clinical case revealed a highly relevant correlation between insulin resistance and a local dental inflammation. To avoid an increase in insulin resistance, it seems important to attend to radically non-vital teeth as well as any other dental inflammation in diabetic patients.

    The objective of this study is to evaluate if overcoming the barrier of starting treatment with insulin can lead to better clinical control and a higher level of patient satisfaction with their treatment. This is an observational, multicentre study of patients diagnosed with DM2 who attended primary care centres with poor glycaemic control (A1c≥8%) under treatment with oral antidiabetic drugs (OADs), and who were given motivational treatment to overcome their fear of injections, and started treatment with insulin. The level of satisfaction with the treatment was evaluated using the Diabetes Treatment Satisfaction Questionnaire (DTSQ). The questionnaire was used before initiating the treatment with insulin and in the follow-up visit (3-4 months from the beginning of treatment with basal insulin). A total of 573 patients with a mean age of 64±10 years were recruited. The overall mean score from the DTSQs satisfaction questionnaire was 18.3±6.3, and the change of treatment led to an improvement in patient satisfaction compared to the previous treatment (DTSQc mean score 8.8±5.9). A1c dropped from an initial value of 8.7% (SD 0.8) to 7.5% (SD 0.7) (P<.001). The frequency of hyperglycaemic episodes perceived by the patients was significantly lower after they overcame their fear of injections (35.6% compared to 11.5%; P<.001), but no statistically significant differences were found in the frequency of hypoglycaemic episodes (32% compared to 35%; P=.059). In patients with DM2 poorly controlled with OADs, overcoming a fear of injections and starting treatment with insulin was associated with an overall improvement in satisfaction with the new treatment, and decreased the perception of hyperglycaemic episodes. Glycaemic control and the metabolic profile of the patients also improved to a statistically significant degree with the change of treatment.

    Our prospective pilot study of acupuncture affecting insulin sensitivity on polycystic ovary syndrome (PCOS) combined with insulin resistance (IR) showed that acupuncture had a significant effect on improving the insulin sensitivity of PCOS. But there is still no randomized controlled trial to determine the effect of acupuncture on the insulin sensitivity in women with PCOS and IR. In this article, we present the protocol of a randomized controlled trial to compare the effect of true acupuncture on the insulin sensitivity of these patients compared with metformin and sham acupuncture. Acupuncture may be an effective therapeutic alternative that is superior to metformin and sham acupuncture in improving the insulin sensitivity of PCOS combined with IR. This study is a multi-center, controlled, double-blind, and randomized clinical trial aiming to evaluate the effect of acupuncture on the insulin sensitivity in PCOS combined with IR. In total 342 patients diagnosed with PCOS and IR will be enrolled. Participants will be randomized to one of the three groups: (1) true acupuncture + metformin placebo; (2) sham acupuncture + metformin, and (3) sham acupuncture + metformin placebo. Participants and assessors will be blinded. The acupuncture intervention will be given 3 days per week for a total of 48 treatment sessions during 4 months. Metformin (0.5 g per pill) or placebo will be given, three times per day, and for 4 months. Primary outcome measures are changes in homeostasis model assessment of insulin resistance (HOMA-IR) and improvement rate of HOMA-IR by oral glucose tolerance test (OGTT) and insulin releasing test (Ins). Secondary outcome measures are homeostasis model assessment-β (HOMA-β), area under the curve for glucose and insulin, frequency of regular menstrual cycles and ovulation, body composition, metabolic profile, hormonal profile, questionnaires, side effect profile, and expectation and credibility of treatment. Outcome measures are

    This study investigates if different diabetic treatment regimens affect diabetic foot ulcer healing. From January 2013 to December 2014, 107 diabetic foot ulcers in 85 patients were followed until wound healing, amputation or development of a nonhealing ulcer at the last follow-up visit. Demographic data, diabetic treatment regimens, presence of peripheral vascular disease, wound characteristics, and outcome were collected. Nonhealing wound was defined as major or minor amputation or those who did not have complete healing until the last observation. Median age was 60.0 years (range: 31.1-90.1 years) and 58 cases (68.2%) were males. Twenty-four cases reached a complete healing (healing rate: 22.4%). The median follow-up period in subjects with classified as having chronic wounds was 6.0 months (range: 0.7-21.8 months). Insulin treatment was a part of diabetes management in 52 (61.2%) cases. Insulin therapy significantly increased the wound healing rate (30.3% [20/66 ulcers] vs. 9.8% [4/41 ulcers]) (p = 0.013). In multivariate random-effect logistic regression model, adjusting for age, gender, smoking status, type of diabetes, hypertension, chronic kidney disease, peripheral arterial disease, oral hypoglycemic use, wound infection, involved side, presence of Charcot's deformity, gangrene, osteomyelitis on x-ray, and serum hemoglobin A1C levels, insulin treatment was associated with a higher chance of complete healing (beta ± SE: 15.2 ± 6.1, p = 0.013). Systemic insulin treatment can improve wound healing in diabetic ulcers after adjusting for multiple confounding covariates. © 2017 by the Wound Healing Society.

    Full Text Available Severe hypertriglyceridemia (SH represents a therapeutic emergency because of the possibility of developing cardiovascular events and hyperlipemic acute pancreatitis (PA. Most patients with SH suffer primary or genetic abnormality in lipid metabolism in combination with a precipitating factor such as uncontrolled diabetes mellitus, alcoholism, and drug intake. The standard treatment of hypertriglyceridemia (HTG with omega 3 fatty acids and fibrates, along with dietary changes, has no effect on an emergency situation. There are no clinical guidelines to SH, but therapy with insulin, heparin, a combination of both, plasmapheresis, or octreotide have been tested succesfully. We report the case of a 10-year-old girl with clinical acute pancreatitis and diabetic ketoacidosis debut, along with incidental finding of an SH, who had a good outcome after treatment with insulin intravenous infusion.

In order to make insulin therapy more acceptable to patients, newer formulations of insulin have been developed, such as biphasic insulins. Biphasic insulins conveniently provide both prandial and basal insulin in a single injection. One of the most well-studied biphasic insulins is biphasic insulin aspart 70/30.Objective: Our goal was to review the current literature on the safety and efficacy of biphasic insulin aspart in type 1 and type 2 diabetes.Methods: A MEDLINE search was conducted using the terms “biphasic insulin aspart” to identify clinical studies and reviews.Results: Biphasic insulin aspart more effectively reduces post-prandial glucose compared to other biphasic insulins and basal insulins. Compared to biphasic insulin aspart, fasting glucose levels are lower with NPH, similar with glargine, and similar or lower with biphasic human insulin. Treat-to-target trials have shown that a goal HbA1c below 6.5 or 7% can be achieved with biphasic insulin aspart. The risk of hypoglycemia is similar to or less than that seen with other biphasic insulins or NPH insulin.Conclusion: Biphasic insulin aspart 70/30 is a safe and effective treatment option for patients with diabetes.Keywords: biphasic insulin aspart, insulin, diabetes

    Several instruments evaluate patient-reported outcomes in diabetes mellitus (DM), but almost none are validated for use in Arabic language. The aim of this study is to test the psychometric properties and responsiveness of the Arabic version of the Diabetes Treatment Satisfaction Questionnaire (DTSQs) in Qatar. Ambulatory Arabic speaking DM patients were interviewed at two consecutive time points in Doha, Qatar. The 8-item DTSQs was administered in conjunction with the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and the World Health Organization Quality of Life Measure (WHOQOL-Bref) to assess convergent validity. Reliability was evaluated by internal consistency and item analysis. Construct validity was evaluated using "known groups" comparisons (including gender, insulin use, and HbA1c). Sensitivity of DTSQs scores to the subject's metabolic conditions was determined. One hundred subjects (mean age 50.7) participated. Half (54%) were female. The majority (93%) had Type 2 DM, but 39 (42%) were using insulin. Results revealed satisfactory internal consistency. Metabolic measures (fasting blood glucose and AIC) had significant inverse correlations with DTSQs scores (interview 1, Pearson's r=-0.333 and r=-0.401, respectively, pQatar Arabic DTSQs version was found to be a reliable and valid instrument for the assessment of treatment satisfaction in Arabic diabetes mellitus patients in the country.

    To evaluate glycemic control and pregnancy outcomes among pregnant women with severe insulin resistance treated with 500 units/mL concentrated insulin. Retrospective analysis of gravid women with severe insulin resistance (need for greater than 100 units of insulin per injection or greater than 200 units/d) treated with either 500 units/mL concentrated insulin or conventional insulin therapy. We performed a two-part analysis: 1) between gravid women treated with and without 500 units/mL concentrated insulin; and 2) among gravid women treated with 500 units/mL concentrated insulin, comparing glycemic control before and after its initiation. Seventy-three pregnant women with severe insulin resistance were treated with 500 units/mL concentrated insulin and 78 with conventional insulin regimens. Patients treated with 500 units/mL concentrated insulin were older and more likely to have type 2 diabetes mellitus. Average body mass index was comparable between both groups (38.6 compared with 40.4, P=.11) as were obstetric and perinatal outcomes and glycemic control during the last week of gestation. Within the 500 units/mL concentrated insulin cohort, after initiation of this medication, fasting and postprandial blood glucose concentrations improved. However, the rates of blood glucose values less than 60 mg/dL and less than 50 mg/dL were higher in the 500 units/mL concentrated insulin group after initiation than before, 4.8% compared with 2.0% (Pinsulin in severely obese insulin-resistant pregnant women confers similar glycemic control compared with traditional insulin regimens but may increase the risk of hypoglycemia.

Several insulin options are available for each species, including veterinary registered products and human insulin preparations. The insulin chosen depends on the individual patient's requirements. Intermediate-acting insulin is usually the first choice for dogs, and longer-acting insulin is the first choice for cats. Once the insulin type is chosen, the best method of insulin administration should be considered. Traditionally, insulin vials and syringes have been used, but insulin pen devices have recently entered the veterinary market. Pens have different handling requirements when compared with standard insulin vials including: storage out of the refrigerator for some insulin preparations once pen cartridges are in use; priming of the pen to ensure a full dose of insulin is administered; and holding the pen device in place for several seconds during the injection. Many different types of pen devices are available, with features such as half-unit dosing, large dials for visually impaired people, and memory that can display the last time and dose of insulin administered. Insulin pens come in both reusable and disposable options. Pens have several benefits over syringes, including improved dose accuracy, especially for low insulin doses.

    2018-05-01

    Full Text Available The efficacy of diabetes treatment should not be evaluated solely by HbA1c levels as they should also focus on patient-reported outcomes (PROs, such as patient satisfaction, wellbeing and quality of life. The Diabetes Treatment Satisfaction Questionnaire (DTSQ has been developed to assess patient satisfaction with diabetes treatment. DTSQ has been translated into more than 100 languages and is widely used in many countries, since it is relatively easy to answer and is used for both patients with and without medical therapy. Novel therapeutic options, such as insulin analogs, incretin-based therapy and sodium-glucose cotransporter 2 (SGLT2 inhibitors, have been shown to improve patient satisfaction using DTSQ for assessments. DTSQ is not only used for comparisons between different medications or treatment strategies, but also can be used to assess the quality of diabetes care in clinical settings. This is important as an improvement in treatment satisfaction may enhance patients’ self-efficacy and adherence to therapy, leading to the achievement of long-term stable glycemic control and reduced risk of diabetic complications. In this review, we summarize the current topics in DTSQ, introducing our own experience, and discuss the role of PROs in diabetes treatment.

  6. Central nervous insulin resistance: a promising target in the treatment of metabolic and cognitive disorders?

    2009-11-01

    Research on functions and signalling pathways of insulin has traditionally focused on peripheral tissues such as muscle, fat and liver, while the brain was commonly believed to be insensitive to the effects of this hormone secreted by pancreatic beta cells. However, since the discovery some 30 years ago that insulin receptors are ubiquitously found in the central nervous system, an ever-growing research effort has conclusively shown that circulating insulin accesses the brain, which itself does not synthesise insulin, and exerts pivotal functions in central nervous networks. As an adiposity signal reflecting the amount of body fat, insulin provides direct negative feedback to hypothalamic nuclei that control whole-body energy and glucose homeostasis. Moreover, insulin affects distinct cognitive processes, e.g. by triggering the formation of psychological memory contents. Accordingly, metabolic and cognitive disorders such as obesity, type 2 diabetes mellitus and Alzheimer's disease are associated with resistance of central nervous structures to the effects of insulin, which may derive from genetic polymorphisms as well as from long-term exposure to excess amounts of circulating insulin due to peripheral insulin resistance. Thus, overcoming central nervous insulin resistance, e.g. by pharmacological interventions, appears to be an attractive strategy in the treatment and prevention of these disorders. Enhancement of central nervous insulin signalling by administration of intranasal insulin, insulin analogues and insulin sensitisers in basic research approaches has yielded encouraging results that bode well for the successful translation of these effects into future clinical practice.

  7. Sustained Treatment with Insulin Detemir in Mice Alters Brain Activity and Locomotion.

    Full Text Available Recent studies have identified unique brain effects of insulin detemir (Levemir®. Due to its pharmacologic properties, insulin detemir may reach higher concentrations in the brain than regular insulin. This might explain the observed increased brain stimulation after acute insulin detemir application but it remained unclear whether chronic insulin detemir treatment causes alterations in brain activity as a consequence of overstimulation.In mice, we examined insulin detemir's prolonged brain exposure by continuous subcutaneous (s.c. application using either micro-osmotic pumps or daily s.c. injections and performed continuous radiotelemetric electrocorticography and locomotion recordings.Acute intracerebroventricular injection of insulin detemir activated cortical and locomotor activity significantly more than regular insulin in equimolar doses (0.94 and 5.63 mU in total, suggesting an enhanced acute impact on brain networks. However, given continuously s.c., insulin detemir significantly reduced cortical activity (theta: 21.3±6.1% vs. 73.0±8.1%, P<0.001 and failed to maintain locomotion, while regular insulin resulted in an increase of both parameters.The data suggest that permanently-increased insulin detemir levels in the brain convert its hyperstimulatory effects and finally mediate impairments in brain activity and locomotion. This observation might be considered when human studies with insulin detemir are designed to target the brain in order to optimize treatment regimens.

    Full Text Available Richard WA Mackenzie, Bradley T Elliott Department of Human and Health Sciences, Facility of Science and Technology, University of Westminster, London, UK Abstract: Type 2 diabetes is a metabolic disease categorized primarily by reduced insulin sensitivity, β-cell dysfunction, and elevated hepatic glucose production. Treatments reducing hyperglycemia and the secondary complications that result from these dysfunctions are being sought after. Two distinct pathways encourage glucose transport activity in skeletal muscle, ie, the contraction-stimulated pathway reliant on Ca2+/5′-monophosphate-activated protein kinase (AMPK-dependent mechanisms and an insulin-dependent pathway activated via upregulation of serine/threonine protein kinase Akt/PKB. Metformin is an established treatment for type 2 diabetes due to its ability to increase peripheral glucose uptake while reducing hepatic glucose production in an AMPK-dependent manner. Peripheral insulin action is reduced in type 2 diabetics whereas AMPK signaling remains largely intact. This paper firstly reviews AMPK and its role in glucose uptake and then focuses on a novel mechanism known to operate via an insulin-dependent pathway. Inositol hexakisphosphate (IP6 kinase 1 (IP6K1 produces a pyrophosphate group at the position of IP6 to generate a further inositol pyrophosphate, ie, diphosphoinositol pentakisphosphate (IP7. IP7 binds with Akt/PKB at its pleckstrin homology domain, preventing interaction with phosphatidylinositol 3,4,5-trisphosphate, and therefore reducing Akt/PKB membrane translocation and insulin-stimulated glucose uptake. Novel evidence suggesting a reduction in IP7 production via IP6K1 inhibition represents an exciting therapeutic avenue in the treatment of insulin resistance. Metformin-induced activation of AMPK is a key current intervention in the management of type 2 diabetes. However, this treatment does not seem to improve peripheral insulin resistance. In light of this

    Full Text Available Abstract Objectives Measurement of treatment satisfaction in diabetes is important as it has been shown to be associated with positive outcomes, reduced disease cost and better health. The aim of this study was to assess the construct validity and internal consistency reliability of the Greek version of the Diabetes Treatment Satisfaction Questionnaire (DTSQ. Methods A sample of type II diabetes patients (N = 172 completed the DTSQ status version, the SF-36 health survey and also provided data regarding treatment method, clinical and socio-demographic status. Instrument structure, reliability (Cronbach's a and construct validity (convergent, discriminative, concurrent and known-groups were assessed. Results The DTSQ measurement properties were confirmed in the Greek version with confirmatory factor analysis (CFA. Scale reliability was high (Cronbach's a = 0.92. Item-scale internal consistency and discriminant validity were also good, exceeding the designated success criteria. Significant correlations were observed between DTSQ items/overall score and SF-36 scales/component scores, which were hypothesized to measure similar dimensions. Known groups' comparisons yielded consistent support of the construct validity of the instrument. Conclusions The instrument was well-accepted by the patients and its psychometric properties were similar to those reported in validation studies of other language versions. Further research, incorporating a longitudinal study design, is required for examining test-retest reliability and responsiveness of the instrument, which were not addressed in this study. Overall, the present results confirm that the DTSQ status version is a reasonable choice for measuring diabetes treatment satisfaction in Greece.

    To develop and evaluate the psychometric properties of a Chinese questionnaire which assesses the barriers and enablers to commencing insulin in primary care patients with poorly controlled Type 2 diabetes. Questionnaire items were identified using literature review. Content validation was performed and items were further refined using an expert panel. Following translation, back translation and cognitive debriefing, the translated Chinese questionnaire was piloted on target patients. Exploratory factor analysis and item-scale correlations were performed to test the construct validity of the subscales and items. Internal reliability was tested by Cronbach's alpha. Twenty-seven identified items underwent content validation, translation and cognitive debriefing. The translated questionnaire was piloted on 303 insulin naïve (never taken insulin) Type 2 diabetes patients recruited from 10 government-funded primary care clinics across Hong Kong. Sufficient variability in the dataset for factor analysis was confirmed by Bartlett's Test of Sphericity (P 0.4 and Eigenvalues >1. Total variance for the 10 factors was 66.22%. Kaiser-Meyer-Olkin measure was 0.725. Cronbach's alpha coefficients for the first four factors were ≥0.6 identifying four sub-scales to which 13 items correlated. Remaining sub-scales and items with poor internal reliability were deleted. The final 13-item instrument had a four scale structure addressing: 'Self-image and stigmatization'; 'Factors promoting self-efficacy; 'Fear of pain or needles'; and 'Time and family support'. The Chinese Attitudes to Starting Insulin Questionnaire (Ch-ASIQ) appears to be a reliable and valid measure for assessing barriers to starting insulin. This short instrument is easy to administer and may be used by healthcare providers and researchers as an assessment tool for Chinese diabetic primary care patients, including the elderly, who are unwilling to start insulin.

    We examined whether 0.9 mg/day liraglutide plus basal insulin (Lira-basal) is superior to basal-bolus insulin therapy (BBIT) for type 2 diabetes (T2DM) without severe insulin deficiency as determined by glucagon stimulation. Fifty patients receiving BBIT were enrolled in this 24-week, prospective, randomized, open-labeled study. After excluding subjects with fasting C-peptide immunoreactivity (CPR) basal (n = 12) or continued BBIT (n = 13). Primary endpoint was change in HbA1c. Secondary endpoints were changes in body weight (BW), 7-point self-monitored blood glucose (SMBG), and Diabetes Treatment Satisfaction Questionnaire status (DTSQs) scores. The Lira-basal group demonstrated reduced HbA1c, whereas the BBIT group showed no change. BW was reduced in the Lira-basal group but increased in the BBIT group. The Lira-basal group also exhibited significantly reduced pre-breakfast and pre-lunch SMBG. DTSQs scores improved in the Lira-basal group but not the BBIT group. Plasma lipids, liver function, and kidney function were not significantly changed in either group. Lira-basal therapy is superior to BBIT for T2DM without severe insulin deficiency.

    Full Text Available Background/Aim. The aim of this study, which included patients with insulin-dependent diabetes mellitus, was to determine the influence of the application of various treatment modalities (intensive or conventional on the total plasma antioxidative capacity and lipid peroxidation intensity expressed as malondialdehyde (MDA level, catalase and xanthine oxidase activity, erythrocyte glutatione reduced concentration (GSH RBC, erythrocyte MDA level (MDA RBC, as well as susceptibility of erythrocyte to H2O2-induced oxidative stress. Methods. This study included 42 patients with insulin-dependent diabetes mellitus. In 24 of the patients intensive insulin treatment was applied using the model of short-acting insulin in each meal and medium- acting insulin before going to bed, while in 18 of the patients conventional insulin treatment was applied in two (morning and evening doses. In the examined patients no presence of diabetes mellitus complications was recorded. The control group included 20 healthy adults out of a blood doner group. The plasma and erythrocytes taken from the blood samples were analyzed immediately. Results. This investigation proved that the application of intensive insulin treatment regime significantly improves total antioxidative plasma capacity as compared to the application of conventional therapy regime. The obtained results showed that the both plasma and lipoproteines apo B MDA increased significantly more in the patients on conventional therapy than in the patients on intensive insulin therapy, most probably due to intensified xanthine oxidase activity. The level of the MDA in fresh erythrocytes did not differ significantly between the groups on intensive and conventional therapy. The level of GSH and catalase activity, however, were significantly reduced in the patients on conventional therapy due to the increased susceptibility to H2O2-induced oxidative stress . Conclusion. The presented study confirmed positive effect of

    A study of the glycemic control, quality of life, and fear and perception of hypoglycemia by comparing continuous subcutaneous insulin infusion (CSII) group with multiple daily inyections (MDI) with bolus calculator group. This is a retrospective cohort study with following up during the first 12 months that CSII group (n=30) begins the use of "bolus wizard" and the MDI-calculator (n=30) group begins the use of the bolus calculator (Accu-Chek(®) Aviva Expert). HbA1c (3, 6 and 12 months). Questionnaires used: EsDQOL (quality of life), FH-15 (fear of hypoglycemia), and Clarke (perception of hypoglycemia). T Student and nonparametric tests. The average reduction in HbA1c during the study was significantly higher in CSII group (-0.56±0.84%) compared with the MDI group (0.097±0.94%), P=.028. The average basal insulin dose was significantly higher in the MDI group (at baseline, 6 and 12 months). No significant differences were found between the 2 treatment groups after analyzing the EsDQOL, FH-15 and Clarke questionnaires. In the CSII group, perceived quality of life assessed by the EsDQOL questionnaire was found to be better at the end of the study than at the beginning of using the insulin pump. The average reduction in HbA1c was significantly higher in the CSII group. In the CSII group, perceived quality of life was better at the end of the study than at the beginning.

    Spontaneously hypertensive rats (SHRs) exhibit endothelial dysfunction and insulin resistance. Reciprocal relationships between endothelial dysfunction and insulin resistance may contribute to hypertension by causing imbalanced regulation of endothelial-derived vasodilators (e.g., nitric oxide) and vasoconstrictors (e.g., endothelin-1 [ET-1]). Treatment of SHRs with rosiglitazone (insulin sensitizer) and/or enalapril (ACE inhibitor) may simultaneously improve hypertension, insulin resistance, and endothelial dysfunction by rebalancing insulin-stimulated production of vasoactive mediators. When compared with WKY control rats, 12-week-old vehicle-treated SHRs were hypertensive, overweight, and insulin resistant, with elevated fasting levels of insulin and ET-1 and reduced serum adiponectin levels. In mesenteric vascular beds (MVBs) isolated from vehicle-treated SHRs and preconstricted with norepinephrine (NE) ex vivo, vasodilator responses to insulin were significantly impaired, whereas the ability of insulin to oppose vasoconstrictor actions of NE was absent (versus WKY controls). Three-week treatment of SHRs with rosiglitazone and/or enalapril significantly reduced blood pressure, insulin resistance, fasting insulin, and ET-1 levels and increased adiponectin levels to values comparable with those observed in vehicle-treated WKY controls. By restoring phosphatidylinositol 3-kinase-dependent effects, rosiglitazone and/or enalapril therapy of SHRs also significantly improved vasodilator responses to insulin in MVB preconstricted with NE ex vivo. Taken together, our data provide strong support for the existence of reciprocal relationships between endothelial dysfunction and insulin resistance that may be relevant for developing novel therapeutic strategies for the metabolic syndrome.

    Basal and bolus insulin therapy is required for strict blood control in diabetic patients, which could lead to prevention of vascular complications in diabetes. However, the optimal combination regimen is not well established. Fifty-nine diabetic patients (49 type 1 and 10 type 2; 52.9 ± 13.3 years old) whose blood glucose levels were uncontrolled (HbA1c  > 6.2%) by combination treatment of basal insulin glargine with multiple daily pre-meal injections of bolus short-acting insulin [aspart (n = 19), lispro (n = 37) and regular human insulin (n = 3)] for at least 8 weeks were enrolled in this study. We examined whether glycaemic control and vascular injury were improved by replacement of short-acting insulin with glulisine. Patient satisfaction was assessed with Diabetes Treatment Satisfaction Questionnaire. Although bolus and basal insulin doses were almost unchanged before and after replacement therapy, switching to glulisine insulin for 24 weeks significantly decreased level of HbA1c , advanced glycation end products (AGEs), soluble receptor for AGEs (sRAGE), monocyte chemoattractant protein-1 (MCP-1) and urinary albumin excretion. In multiple stepwise regression analysis, change in MCP-1 values from baseline (ΔMCP-1) was a sole determinant of log urinary albumin excretion. ΔAGEs and ΔsRAGE were independently correlated with each other. The relationship between ΔMCP-1 and ΔsRAGE was marginally significant (p = 0.05). Replacement of short-acting insulin by glulisine significantly increased Diabetes Treatment Satisfaction Questionnaire scores. Our present study suggests that combination therapy of glargine with multiple daily pre-meal injections of glulisine might show superior efficacy in controlling blood glucose, preventing vascular damage and improving treatment satisfaction in diabetic patients.

    Addition of the GLP-1 receptor agonist liraglutide to insulin can reverse insulin-associated weight gain, improve HbA1c and decrease the need for insulin, but is expensive. From a cost perspective, such treatment should be discontinued when it is clear that treatment targets will not be achieved. Our aim was to find the best cost-controlling treatment strategy: the shortest possible trial period needed to discriminate successfully treated patients from those failing to achieve predefined targets of treatment success. We used data from the 'Effect of Liraglutide on insulin-associated wEight GAiN in patients with Type 2 diabetes' (ELEGANT) trial, comparing additional liraglutide (n = 47) and standard insulin therapy (n = 24) during 26 weeks, to calculate the costs associated with different trial periods. Treatment success after 26 weeks was defined by having achieved ≥ 2 of the following: ≥ 4% weight loss, HbA1c ≤ 53 mmol/mol (7%), and/or discontinuation of insulin. The additional direct costs of adding liraglutide for 26 weeks were € 699 per patient, or € 137 per 1 kg weight loss, compared with standard therapy. The best cost-controlling treatment strategy (identifying 21 of 23 responders, treating four non-responders) was to continue treatment in patients showing ≥ 3% weight loss or ≥ 60% decrease in insulin dose at 8 weeks, with a total cost of € 246 for this t rial period, saving € 453 in case of early discontinuation. An 8-week trial period of adding liraglutide to insulin in patients with insulin-associated weight gain is an effective cost-controlling treatment strategy if the liraglutide is discontinued in patients not showing an early response regarding weight loss or insulin reduction.

    To compare the persistence (treatment duration) of basal insulin supported oral therapy (BOT) using insulin glargine (GLA) or NPH insulin (NPH) in Type-2 diabetic patients. This retrospective cohort study reports results from an analysis of claims data from prescriptions for ambulatory patients within the German Statutory Health Insurance scheme. The study is based on claims data from more than 80% of German community pharmacies. Treatment duration until switching to a basal bolus treatment regimen (intensified conventional insulin therapy: ICT) was determined in insulin-naïve patients who began treatment with BOT using GLA or NPH between 01/2003 and 12/2006. A total of 97,998 patients (61,070 GLA and 36,928 NPH) were included. Within the observation period, 23.5% of GLA patients and 28.0% of NPH patients switched from BOT to ICT. The upper quartile of probability of continuation of therapy (the 75th percentile) was reached after 769 days in GLA patients and after 517 days in NPH patients. Therefore, the risk of switching to ICT was significantly higher with NPH compared to GLA: hazard ratios were 1.34 (99% CI: 1.29-1.38; unadjusted) and 1.22 (99% CI: 1.18-1.27) after adjustment for predefined covariates. Various sensitivity analyses using modified inclusion criteria and endpoint definitions were applied and these confirmed the initial results. Type-2 diabetic patients under BOT with GLA stayed significantly longer on the initial therapy before switching to ICT than patients on BOT using NPH.

    Full Text Available Priscilla A Hollander1,21Baylor Endocrine Center, 2Baylor Medical Center, Dallas, Texas, USAAbstract: The risk for developing type 2 diabetes (T2DM is greater among obese individuals. Following onset of the disease, patients with T2DM become more likely to be afflicted with diabetic micro- and macrovascular complications. Decreasing body weight has been shown to lower glycosylated hemoglobin and improve other metabolic parameters in patients with T2DM. Medications used to lower blood glucose may increase body weight in patients with T2DM and this has been repeatedly shown to be the case for conventional, human insulin formulations. Insulin detemir is a neutral, soluble, long-acting insulin analog in which threonine-30 of the insulin B-chain is deleted, and the C-terminal lysine is acetylated with myristic acid, a C14 fatty acid chain. Insulin detemir binds to albumin, a property that enhances its pharmacokinetic/pharmacodynamic profile. Results from clinical trials have demonstrated that treatment with insulin detemir is associated with less weight gain than either insulin glargine or neutral protamine Hagedorn insulin. There are many potential reasons for the lower weight gain observed among patients treated with insulin detemir, including lower risk for hypoglycemia and therefore decreased defensive eating due to concern about this adverse event, along with other effects that may be related to the albumin binding of this insulin that may account for lower within-patient variability and consistent action. These might include faster transport across the blood–brain barrier, induction of satiety signaling in the brain, and preferential inhibition of hepatic glucose production versus peripheral glucose uptake. Experiments in diabetic rats have also indicated that insulin detemir increases adiponectin levels, which is associated with both weight loss and decreased eating.Keywords: basal insulin, body mass index, detemir, insulin analog, satiety

    Full Text Available Background and aims: Insulin resistance (IR is a common pathogenic factor of several diseases: diabetes mellitus, the metabolic syndrome, arterial hypertension, atherosclerosis, dyslipidemia, etc. There are many therapeutic factors involved in decreasing IR. Among them we mention metformin, pioglitazone, physical activity, weight loss, diet, etc. In the last decade, there are more observations of the influence of polyunsaturated fatty acids on IR. The most powerful seem to be omega-3 fatty acids. In our study, we wanted to asses if the administration of omega-3 fatty acids is involved in modifying IR. Materials and methods: We evaluated 126 diabetic patients with IR from January 2011 until July 2014. The study was open-label and non-randomized. For the determination of IR we used the HOMA-IR method. Results: For both males and females there was a regression of HOMA-IR during the 4 weeks of treatment with omega-3 and also after 2 weeks after stopping the administration of these fatty acids. The decrease of HOMA-IR was statistically significant (p<0.05. The statistic result observed in the next 2 weeks after stopping administration of omega-3 was also significant (p<0.05.

    Insulin resistance is manifested by decreased effect of fixed quantity of insulin on glucose metabolism leading to type 2 diabetes mellitus. Visceral obesity has been positively correlated with insulin resistance but its mechanism is not fully defined. Insulin resistance may be the consequence of adipocytokines including visfatin and resistin. This study was designed to see the effect of thiazolidinediones on levels of resistin in insulin resistant rats. Methods: Ninety Sprague Dawley rats were randomly divided into three groups. Group I served as control. Rats in Group II and III were made insulin resistant diabetics. Group III was treated with rosiglitazone after development of diabetes. Plasma glucose, serum triglycerides, HDL, TG:HDL ratio and serum resistin levels were analysed. Results: Body weight and plasma glucose were significantly increased (p<0.05) along with TG:HDL ratio (p<0.05) in group II and group III at the end of 4th week. Serum resistin levels also increased significantly (p<0.05) in group II and III at the end of 4th week. Treatment of group III with rosiglitazone led to improvement in insulin resistance with decrease in serum resistin levels (p<0.05). Conclusion: Increased serum resistin level indicates insulin resistance and impending hyperglycaemia. Thiazolidinediones augment sensitivity of insulin to restore normoglycaemia by decreasing serum resistin level. (author)

  5. Cytochrome C is tyrosine 97 phosphorylated by neuroprotective insulin treatment.

    Directory of Open Access Journals (Sweden)

    Thomas H Sanderson

    Full Text Available Recent advancements in isolation techniques for cytochrome c (Cytc have allowed us to discover post-translational modifications of this protein. We previously identified two distinct tyrosine phosphorylated residues on Cytc in mammalian liver and heart that alter its electron transfer kinetics and the ability to induce apoptosis. Here we investigated the phosphorylation status of Cytc in ischemic brain and sought to determine if insulin-induced neuroprotection and inhibition of Cytc release was associated with phosphorylation of Cytc. Using an animal model of global brain ischemia, we found a ∼50% decrease in neuronal death in the CA1 hippocampal region with post-ischemic insulin administration. This insulin-mediated increase in neuronal survival was associated with inhibition of Cytc release at 24 hours of reperfusion. To investigate possible changes in the phosphorylation state of Cytc we first isolated the protein from ischemic pig brain and brain that was treated with insulin. Ischemic brains demonstrated no detectable tyrosine phosphorylation. In contrast Cytc isolated from brains treated with insulin showed robust phosphorylation of Cytc, and the phosphorylation site was unambiguously identified as Tyr97 by immobilized metal affinity chromatography/nano-liquid chromatography/electrospray ionization mass spectrometry. We next confirmed these results in rats by in vivo application of insulin in the absence or presence of global brain ischemia and determined that Cytc Tyr97-phosphorylation is strongly induced under both conditions but cannot be detected in untreated controls. These data suggest a mechanism whereby Cytc is targeted for phosphorylation by insulin signaling, which may prevent its release from the mitochondria and the induction of apoptosis.

    Highlights: {yields} Anti-diabetic new drug, DPP-4 inhibitor, can affect the insulin exocytosis. {yields} DPP-4 inhibitor treatment altered syntaxin 1 expression. {yields} Treatment of db/db mice with DPP-4 inhibitor increased insulin release. -- Abstract: Incretin promotes insulin secretion acutely. Recently, orally-administered DPP-4 inhibitors represent a new class of anti-hyperglycemic agents. Indeed, inhibitors of dipeptidyl peptidase-IV (DPP-4), sitagliptin, has just begun to be widely used as therapeutics for type 2 diabetes. However, the effects of sitagliptin-treatment on insulin exocytosis from single {beta}-cells are yet unknown. We therefore investigated how sitagliptin-treatment in db/db mice affects insulin exocytosis by treating db/db mice with des-F-sitagliptin for 2 weeks. Perfusion studies showed that 2 weeks-sitagliptin treatment potentiated insulin secretion. We then analyzed insulin granule motion and SNARE protein, syntaxin 1, by TIRF imaging system. TIRF imaging of insulin exocytosis showed the increased number of docked insulin granules and increased fusion events from them during first-phase release. In accord with insulin exocytosis data, des-F-sitagliptin-treatment increased the number of syntaxin 1 clusters on the plasma membrane. Thus, our data demonstrated that 2-weeks des-F-sitagliptin-treatment increased the fusion events of insulin granules, probably via increased number of docked insulin granules and that of syntaxin 1 clusters.

    The effects of pertussis toxin (PT) treatment on insulin-stimulated myristoyl-diacylglycerol (DAG) generation, hexose transport, and thymidine incorporation were studied in differentiated BC3H-1 mycocytes. Insulin treatment caused a biphasic increase in myristoyl-DAG production which was abolished in myocytes treated with PT. There was no effect of PT treatment on basal (nonstimulated) myristoyl-DAG production. Insulin-stimulated hydrolysis of a membrane phosphatidylinositol glycan was blocked by PT treatment. ADP-ribosylation of BC3H-1 plasma membranes with [ 32 P]NAD revealed a 40-kDa protein as the major PT substrate in vivo and in vitro. The time course and dose dependence of the effects of PT on diacylglycerol generation correlated with the in vivo ADP-ribosylation of the 40-kDa substrate. Pertussis toxin treatment resulted in a 71% attenuation of insulin-stimulated hexose uptake without effect on either basal or phorbol ester-stimulated uptake. The stimulatory effects of insulin and fetal calf serum on [ 3 H]thymidine incorporation into quiescent myocytes were attenuated by 61 and 59%, respectively, when PT was added coincidently with the growth factors. Nonstimulated and EGF-stimulated [ 3 H]thymidine incorporation was unaffected by PT treatment. These data suggest that a PT-sensitive G protein is involved in the cellular signaling mechanisms of insulin

    Inflammation associated with obesity is involved in the development of insulin resistance. We hypothesized that anti-inflammatory treatment with the Interleukin-1 receptor antagonist anakinra would improve insulin sensitivity. In an open label proof-of-concept study, we included overweight patients diagnosed with type 1 diabetes with an HbA1c level over 7.5%. Selecting insulin resistant patients with longstanding type 1 diabetes allowed us to study the effects of anakinra on insulin sensitivity. Patients were treated with 100mg anakinra daily for one week. Insulin sensitivity, insulin need and blood glucose profiles were measured before, after one week and after four weeks of follow-up. Fourteen patients completed the study. One week of anakinra treatment led to an improvement of insulin sensitivity, an effect that was sustained for four weeks. Similarly, glucose profiles, HbA1c levels and insulin needs improved. In conclusion, one week of treatment with anakinra improves insulin sensitivity in patients with type 1 diabetes.

    Little is known regarding perception of insulin treatment among midlife and older African American (AA) adults with type 2 diabetes, or how perception affects self-management behaviors. Using the Roy adaptation model, this qualitative descriptive study explored the perception of insulin treatment in midlife and older AAs living with uncontrolled type 2 diabetes. Three 1-hour focus groups were conducted with a total of 13 participants. Thematic analysis of transcribed audio recordings used the constant comparative method. Themes identified include (a) insulin as instigator of negative emotions, (b) adapting to a lifestyle with insulin, and (c) becoming an insulin user: a new identity. Adapting to insulin is a psychosocial process that commonly results in negative emotions, identity conflict, and new roles. Further research is needed to understand how AA adults perceive insulin treatment, understand the role of perception in self-management behaviors, and determine whether interventions to change perceptions may be effective in improving adaptation to diabetes. © The Author(s) 2014.

  10. Insulin treatment promotes tyrosine phosphorylation of PKR and inhibits polyIC induced PKR threonine phosphorylation.

    Tyrosine phosphorylation of insulin receptor beta (IRβ) in insulin treated HepG2 cells is inversely correlated to ser(51) phosphorylation in the alpha-subunit of eukaryotic initiation factor 2 (eIF2α) that regulates protein synthesis. Insulin stimulates interaction between IRβ and PKR, double stranded RNA-dependent protein kinase, also known as EIF2AK2, and phosphorylation of tyrosine residues in PKR, as analyzed by immunoprecipitation and pull down assays using anti-IRβ and anti-phosphotyrosine antibodies, recombinant IRβ and immunopurified PKR. Further polyIC or synthetic double stranded RNA-induced threonine phosphorylation or activation of immunopurified and cellular PKR is suppressed in the presence of insulin treated purified IRβ and cell extracts. Acute, but not chronic, insulin treatment enhances tyrosine phosphorylation of IRβ, its interaction with PKR and tyrosine phosphorylation of PKR. In contrast, lipopolysaccharide that stimulates threonine phosphorylation of PKR and eIF2α phosphorylation and AG 1024, an inhibitor of the tyrosine kinase activity of IRβ, reduces PKR association with the receptor, IRβ in HepG2 cells. These findings therefore may suggest that tyrosine phosphorylated PKR plays a role in the regulation of insulin induced protein synthesis and in maintaining insulin sensitivity, whereas, suppression of polyIC-mediated threonine phosphorylation of PKR by insulin compromises its ability to fight against virus infection in host cells.

    The role of insulin in the mechanism underlying the excessive fluoride that causes skeletal lesion was studied. The in vitro bone marrow stem cells (BMSC) collected from Kunming mice were exposed to varying concentrations of fluoride with or without insulin. The cell viability and early differentiation of BMSC co-treated with fluoride and insulin were measured by using cell counting kit-8 and Gomori modified calcium-cobalt method, respectively. We further investigated the in vivo effects of varying dose of fluoride on rats co-treated with streptozotocin (STZ). Wistar rats were divided into six groups which included normal control, 10 mg fluoride/kg day group, 20 mg fluoride/kg day group, STZ control, STZ+10 mg fluoride/kg day group, and STZ+20 mg fluoride/kg day group. The rats were administered with sodium fluoride (NaF) by gavage with water at doses 10 and 20 mg fluoride/kg day for 2 months. In a period of one month, half of rats in every group were treated with streptozotocin (STZ) once through intraperitoneal injection at 52 mg/kg body weight. The serum glucose, HbA1c, and insulin were determined. Bone mineral content and insulin release were assessed. The results showed insulin combined with fluoride stimulated BMSC cell viability in vitro. The bone mineral content reduced in rats treated with higher dose of fluoride and decreased immensely in rat co-treated with fluoride and STZ. Similarly, a combination treatment of a high dose of fluoride and STZ decreased insulin sensitivity and activity. To sum up, these data indicated fluoride influenced insulin release, activity, and sensitivity. Furthermore, the insulin state in vivo interfered in the osteogenesis in turn and implied there was a close relation between insulin and bone pathogenesis in the mechanism of fluoride toxicity.

    Although legal, formal, and informal social controls are frequently used to pressure individuals to enter treatment, motivational consequences of using these tactics have been neglected. Self-determination theory (SDT) provides a useful perspective for understanding client experiences of social controls and highlights the importance of self-determined motivation for long-term behavior change. This study assessed the construct validity of the Treatment Entry Questionnaire (TEQ), a brief scale derived from SDT to measure identified, introjected, and external treatment motivation. Two independent samples of clients entering Canadian residential and outpatient treatment completed TEQ items (ns = 529 and 623). Exploratory and confirmatory factor analyses supported a 9-item version of the scale, with 3 factors aligning with SDT motivational subtypes. Subscales showed high internal consistency and correlated as expected with social controls and perceived coercion at treatment entry. The TEQ-9 is a valid option for assessing self-determined motivation in clinical practice and evaluating coerced addiction treatment. Copyright © 2012 Elsevier Inc. All rights reserved.

    2010-01-01

    Full Text Available Insulin detemir is a long-acting basal insulin approved for use in patients with type 1 (T1DM or type 2 diabetes (T2DM. Insulin detemir has demonstrated equivalent glycemic control and hypoglycemic risk when compared to insulin glargine, and insulin detemir has generally but not consistently demonstrated less weight gain than insulin glargine in T2DM. The benefits of basal insulin analogs relative to NPH insulin are well recognized, including less FBG variability, lower risk of hypoglycemia, and less weight gain specifically with insulin detemir. However, NPH insulin continues to be widely prescribed, which may be due in part to economic considerations. While NPH insulin generally costs less per prescription, insulin detemir has been shown to be cost effective compared to NPH insulin as well as insulin glargine. Therefore, insulin detemir is an effective option from both clinical and economic perspectives for patients with T1DM or T2DM who require basal insulin to achieve glycemic control.

    To compare the efficacy of metformin in the treatment of gestational diabetes mellitus (GDM) with insulin and to compare the frequency of hypoglycaemia in neonates of the mothers treated with metformin and insulin. Study Design: Randomized control trial to compare the efficacy of metformin with insulin in the treatment of GDM. Place and Duration of Study: Outpatient department and labour ward of Obstetric and Gynaecology department of Benazir Bhutto Hospital Rawalpindi from August 2012 to January 2013. Patients and Method: A total of 110 pregnant ladies with GDM diagnosed after 20 weeks of gestation were included and divided into group A and group B with 55 patients in each group. Group A patients were treated with insulin and group B with metformin. Plasma fasting glucose and two hours postprandial glucose levels were determined on weekly basis for four weeks after starting the treatment to determine the efficacy of insulin and metformin. At birth plasma glucose levels of all the neonates were carried out two hourly, and more frequently depending upon the requirement, during first 24 hours in both the groups to determine neonatal hypoglycaemia. Results: Fasting plasma glucose in group A and B were calculated as 5.96 ± 0.58 and 5.76 ± 0.46 mmol/L respectively (p=0.280), while two hours post-prandial plasma glucose levels were 7.34 ± 0.48 and 7.28 ± 0.58 mmol/L respectively (p=0.650). Efficacy in group A was 78.18% and in group B was 70.91% (p=0.381) while frequency of neonatal hypoglycaemia was calculated as 61.54% in group A and 41% in group B (p=0.113). Conclusion: The efficacy of metformin in treatment of gestational diabetes mellitus is similar as with insulin and the frequency of hypoglycemia in neonates of the mother treated with metformin and insulin is also similar.

    Objective  To compare the effectiveness of insulin pumps with multiple daily injections for adults with type 1 diabetes, with both groups receiving equivalent training in flexible insulin treatment. Design  Pragmatic, multicentre, open label, parallel group, cluster randomised controlled trial (Relative Effectiveness of Pumps Over MDI and Structured Education (REPOSE) trial). Setting  Eight secondary care centres in England and Scotland. Participants  Adults with type 1 diabetes who were willing to undertake intensive insulin treatment, with no preference for pumps or multiple daily injections. Participants were allocated a place on established group training courses that taught flexible intensive insulin treatment ("dose adjustment for normal eating," DAFNE). The course groups (the clusters) were then randomly allocated in pairs to either pump or multiple daily injections. Interventions  Participants attended training in flexible insulin treatment (using insulin analogues) structured around the use of pump or injections, followed for two years. Main outcome measures  The primary outcomes were a change in glycated haemoglobin (HbA1c) values (%) at two years in participants with baseline HbA1c value of ≥7.5% (58 mmol/mol), and the proportion of participants achieving an HbA1c value of intention to treat analysis, of which 235 (119 pump and 116 injection) had baseline HbA1c values of ≥7.5%. Glycaemic control and rates of severe hypoglycaemia improved in both groups. The mean change in HbA1c at two years was -0.85% with pump treatment and -0.42% with multiple daily injections. Adjusting for course, centre, age, sex, and accounting for missing values, the difference was -0.24% (-2.7 mmol/mol) in favour of pump users (95% confidence interval -0.53 to 0.05, P=0.10). Most psychosocial measures showed no difference, but pump users showed greater improvement in treatment satisfaction and some quality of life domains (dietary freedom and daily hassle) at 12 and 24

    Polycystic ovarian disease (PCOD) is the most important endocrine abnormality that affects women in reproductive age. It is characterized by chronic anovulation and hyperandrogenemia probably secondary to insulin resistance. Hence insulin sensitizers agents had been used in PCOD. Metformin is a biguanide used in the treatment of PCOD via decrease of hepatic gluconeogenesis and insulinemia; improvement peripheral glucose utilization, oxidative glucose metabolism, nonoxidative glucose metabolism and intracellular glucose transport. Such effects, when this drug is administered alone during 3 to 6 months, increase sex hormone binding globulin (SHBG), reduce free androgens index and hirsutism, decrease insulin resistance, and regulate menses in 60 to 70% of cases. Thiazolidinodiones are drugs that decrease insulin resistance in the liver with hepatic glucose production. Their mechanism of action is through the peroxisome proliferator-activated receptors gamma (PPAR-gamma), that help to decrease plasmatic concentrations of free fatty acids, pre and postprandial glucose, insulin, triglycerides, increased HDL cholesterol and decreased LDL, menses return to normality, with improvement of ovulation and decreased hirsutism. It seems that by modulation and attenuation of insulin resistance, hypoglucemic agents such as metfomin and thiazolidinodiones can be used effectively to treat anovulation, infertility and hyperandrogenemia.

    Traumatic brain injury (TBI) results in learning and memory dysfunction. Cognitive deficits result from cellular and metabolic dysfunction after injury, including decreased cerebral glucose uptake and inflammation. This study assessed the ability of intranasal insulin to increase cerebral glucose uptake after injury, reduce lesion volume, improve memory and learning function and reduce inflammation. Adult male rats received a controlled cortical impact (CCI) injury followed by intranasal insulin or saline treatment daily for 14 days. PET imaging of [18F]-FDG uptake was performed at baseline and at 48 h and 10 days post-injury and MRI on days three and nine post injury. Motor function was tested with the beam walking test. Memory function was assessed with Morris water maze. Intranasal insulin after CCI significantly improved several outcomes compared to saline. Insulin-treated animals performed better on beam walk and demonstrated significantly improved memory. A significant increase in [18F]-FDG uptake was observed in the hippocampus. Intranasal insulin also resulted in a significant decrease in hippocampus lesion volume and significantly less microglial immunolabeling in the hippocampus. These data show that intranasal insulin improves memory, increases cerebral glucose uptake and decreases neuroinflammation and hippocampal lesion volume, and may therefore be a viable therapy for TBI.

    CONTEXT: Pegvisomant is a specific GH receptor antagonist that is able to normalize serum IGF-I concentrations in most patients with acromegaly. The impact of pegvisomant on insulin sensitivity and substrate metabolism is less well described. PATIENTS AND METHODS: We assessed basal and insulin......-stimulated (euglycemic clamp) substrate metabolism in seven patients with active acromegaly before and after 4-wk pegvisomant treatment (15 mg/d) in an open design. RESULTS: After pegvisomant, IGF-I decreased, whereas GH increased (IGF-I, 621 +/- 82 vs. 247 +/- 33 microg/liter, P = 0.02; GH, 5.3 +/- 1.5 vs. 10.8 +/- 3...... vs. 1563 +/- 101 kcal/24 h, P = 0.03), but the rate of lipid oxidation did not change significantly. CONCLUSIONS: 1) Pegvisomant treatment for 4 wk improves peripheral and hepatic insulin sensitivity in acromegaly. 2) This is associated with a decrease in resting energy expenditure, whereas free...

    Neonatal diabetes mellitus (NDM) is defined as hyperglycemia and impaired insulin secretion with onset within 6 months of birth. While rare, NDM presents complex challenges regarding the management of glycemic control. The availability of continuous subcutaneous insulin infusion pumps (CSII) in combination with continuous glucose monitoring systems (CGM) provides an opportunity to monitor glucose levels more closely and deliver insulin more safely. We report four cases of young infants with NDM successfully treated with CSII and CGM. Moreover, in two cases with Kir 6.2 mutation, we describe the use of CSII in switching therapy from insulin to sulfonylurea treatment. Insulin pump requirement for the 4 neonatal diabetes cases was the same regardless of disease pathogenesis and c-peptide levels. No dilution of insulin was needed. The use of an integrated CGM system helped in a more precise control of BG levels with the possibility of several modifications of insulin basal rates. Moreover, as showed in the first two case-reports, when the treatment was switched from insulin to glibenclamide, according to identification of Kir 6.2 mutation and diagnosis of NPDM, the CSII therapy demonstrated to be helpful in allowing gradual insulin suspension and progressive introduction of sulfonylurea. During the neonatal period, the use of CSII therapy is safe, more physiological, accurate and easier for the insulin administration management. Furthermore, CSII therapy is safe during the switch of therapy from insulin to glibenclamide for infants with permanent neonatal diabetes mellitus.

    AIM To determine the frequency and causes of blindness in diabetic Africans. METHODS The study was a cross-sectional survey carried out among known black diabetics consecutively admitted at the Teaching Hospital, University of Kinshasa, between 2005 and 2007. Examination methods included interviewer-administered structured questionnaire, eye examinations (visual acuity, tonometry, funduscopy), and fasting plasma glycaemia test. RESULTS Of the 227 patients examined, 15.9% had blindness. Univariate analyses showed significant association between female, severity of diabetic retinopathy, Mayombian ethnic group, use of insulin treatment, low intake of vegetables, diabetic nephropathy, open angle glaucoma and blindness in all diabetics. After logistic regression, only diabetic nephropathy, use of insulin treatment, macular oedema, Mayombian ethnic group and vegetables low intake were the independent risk factors of blindness in all diabetics. However, after logistic regression in the sub-group with diabetic retinopathy, only open angle glaucoma and proliferative diabetic retinopathy were the independent determinants of blindness. CONCLUSION The majority of the causes of blindness in these diabetic Africans are avoidable. It is recommended that appropriate diabetes care, nutrition education, periodic eye examination and laser photocoagulation facilities should be provided for treating diabetics in sub-Saharan Africa.

    To describe patients' and their parents' expectations of orthodontic treatment. A questionnaire survey of 100 patients and their primary care-givers attending a new patient orthodontic consultant clinic, at a teaching hospital. GKT Orthodontic Department, King's College Dental Hospital, London, UK. The sample consisted of 100 participants who completed the questionnaire, including 50 patients aged 12-14 years who had been referred to the orthodontic department for treatment. One parent of each patient was also invited to participate. Participants completed a valid questionnaire measure of orthodontic expectations that was tested for reliability and validity. Descriptive analysis of the responses was undertaken, and comparisons of children's and parents' expectations, in addition to ethnicity, were made. Patients and parents have similar expectations of treatment, with the exception of expectations of duration of orthodontic treatment (Pexpectations of the initial orthodontic assessment visit, the likelihood of wearing headgear, the impact of orthodontic treatment on diet, and the reaction of peers to treatment (Pexpectations regarding the initial visit, headgear and dietary restrictions (Pparents share similar expectations of orthodontic treatment for most aspects of care, although parents are more realistic in their estimation of the duration of treatment and the initial visit. The expectations of patients differ from those of their parents with regard to dietary and drink restrictions in relation to orthodontic treatment. Ethnicity significantly influences expectations of orthodontic treatment, and this may relate to differences in the patients' and their parents' assessed outcome of care.

    We report the case of a 29-year-old man with a 14-year history of type 1 diabetes, normal renal function, and mild diabetic retinopathy. The patient progressively developed a generalized allergic reaction to two insulin excipients--protamine and metacresol--with systemic manifestations of tremor, tachycardia, vertigo, shortness of breath, and short episodes of unconsciousness causing him to be out of work. In June 2003, he received a vascularized cadaveric pancreas transplant using induction with polyclonal antibodies along with tacrolimus and sirolimus but without steroids. A hyperglycemic episode following corticosteroid therapy for rejection treatment required reintroduction of insulin therapy with prompt reappearance of allergic manifestations. Now, the patient is euglycemic without insulin or allergic manifestations and a glycated hemoglobin of 6.4%.

    Intensive insulin treatment in type 1 diabetes reduces the incidence and slows the progression of microvascular and macrovascular complications; however, it is associated with an increased risk of hypoglycaemia and weight gain. In this review, we propose dual-hormone treatment with insulin...... and glucagon as a method for achieving near normalization of blood glucose levels without increasing hypoglycaemia frequency and weight gain. We briefly summarize glucagon pathophysiology in type 1 diabetes as well as the current applications of glucagon for the treatment of hypoglycaemia. Until now, the use...... of glucagon has been limited by the need for reconstitution immediately before use, because of instability of the available compounds; however, stabile compounds are soon to be launched and will render long-term intensive dual-hormone treatment in type 1 diabetes possible....

    Initiating and adjusting insulin treatment for people with type 2 diabetes (T2D) requires frequent clinician contacts both face-to-face and by telephone. We explored the use of a telehealth system to offer additional support to these patients. Twenty-three patients with uncontrolled T2D were recruited from nine general practices to assess the feasibility and acceptability of telehealth monitoring and support for insulin initiation and adjustment. The intervention included a standard algorithm for self-titration of insulin dose, a Bluetooth enabled glucose meter linked to a mobile phone, an integrated diary to record insulin dose, feedback of charted blood glucose data and telehealth nurse review with telephone follow-up. Additional contact with patients was initiated when no readings were transmitted for >3 days or when persistent hyper- or hypoglycaemia was identified. Reponses of patients and clinicians to the system were assessed informally. The mean (SD) patient age was 58 years (12) with 78% male. The mean (SD) diabetes duration was 6.4 years (4.5), HbA1c at baseline was 9.5% (2.2), and the decrease in HbA1c at three months was 0.52% (0.91) with an insulin dose increase of 9 units (26). A mean (SD) of 160 (93) blood glucose readings was transmitted per patient in these three months. Practice nurses and general practitioners (GPs) viewed the technology as having the potential to improve patient care. Most patients were able to use the equipment with training and welcomed review of their blood glucose readings by a telehealth nurse. Although the concept of telehealth monitoring is unfamiliar to most patients and practice nurses, the technology improved the support available for T2D patients commencing insulin treatment.

    This study describes the validation process for the Slovenian version of the Drug Addiction Treatment Efficacy Questionnaire (DATEQ). DATEQ was constructed from the questionnaires used at the Centre for the Treatment of Drug Addiction, Ljubljana University Psychiatric Hospital, and within the network of Centres for the Prevention and Treatment of Drug Addiction in Slovenia during the past 14 years. The Slovenian version of the DATEQ was translated to English using the 'forward-backward' procedure by its authors and their co-workers. The validation process included 100 male and female patients with established addiction to illicit drugs who had been prescribed opioid substitution therapy. The DATEQ questionnaire was used in the study, together with clinical evaluation to measure psychological state and to evaluate the efficacy of treatment in the last year. To determinate the validity of DATEQ the correlation with the clinical assessments of the outcome was calculated using one-way ANOVA. The F value was 44.4, p<0.001 (sum of squares: between groups 210.4, df=2, within groups 229.7, df=97, total 440.1, df=99). At the cut-off 4 the sensitivity is 81% and specificity 83%. The validation process for the Slovenian DATEQ version shows metric properties similar to those found in international studies of similar questionnaires, suggesting that it measures the same constructs, in the same way and as similar questionnaires. However, the relatively low sensitivity and specificity suggests caution when using DATEQ as the only measure of outcome.

    to psychometrically test the Brazilian version of the Treatment Satisfaction Questionnaire for Medication - TSQM (version 1.4), regarding ceiling and floor effect, practicability, acceptability, reliability and validity. participants with coronary heart disease (n=190) were recruited from an outpatient cardiology clinic at a university hospital in Southeastern Brazil and interviewed to evaluate their satisfaction with medication using the TSQM (version 1.4) and adherence using the Morisky Self-Reported Measure of Medication Adherence Scale and proportion of adherence. The Ceiling and Floor effect were analyzed considering the 15% worst and best possible TSQM scores; Practicability was assessed by time spent during TSQM interviews; Acceptability by proportion of unanswered items and participants who answered all items; Reliability through the Cronbach's alpha coefficient and Validity through the convergent construct validity between the TSQM and the adherence measures. TSQM was easily applied. Ceiling effect was found in the side effects domain and floor effect in the side effects and global satisfaction domains. Evidence of reliability was close to satisfied in all domains. The convergent construct validity was partially supported. the Brazilian TSQM presents evidence of acceptability and practicability, although its validity was weakly supported and adequate internal consistency was observed for one domain. realizar o teste psicométrico da versão brasileira do Treatment Satisfaction Questionnaire for Medication - TSQM (versão 1.4) [Questionário Satisfação com Tratamento Medicamentoso] com relação aos efeitos de teto e chão, praticidade, aceitabilidade, confiabilidade e validade. os participantes com doença cardíaca coronária (n=190) foram recrutados num ambulatório de cardiologia de um hospital universitário no sudeste do Brasil e entrevistados para avaliar satisfação em relação ao tratamento medicamentoso através da TSQM (versão 1.4) e ades

    We investigated the safety of the batteries and power units used in insulin pumps in Japan. A self-administered questionnaire was sent to the 201 members of the Association for Innovative Diabetes Treatment in Japan. A total of 56 members responded, and among the 1,499 active devices, 66 had episodes of trouble related to the batteries and power units. The ratio of reported troubles to the number of insulin pumps was significantly higher in insulin pumps with a continuous glucose monitoring sensor compared with insulin pumps without a continuous glucose monitoring sensor (odds ratio 2.82, P batteries varied; alkaline batteries purchased at drug stores and other shops accounted for 19.7%. Termination of battery life within 72 h of use was reported most frequently (50.0%), suspension of the insulin pump (21.2%) and leakage of the battery fluid (4.5%) followed. A total of 53.2% of the reported insulin pumps needed to be replaced, and 37.1% of them recovered after replacement of the battery. As trouble related to the batteries and power units of insulin pumps was frequent, practical guidance should be provided to respective patients regarding the use of reliable batteries, and to be well prepared for unexpected insulin pump failure. © 2017 The Authors.

  17. [Long-acting insulins in the treatment of type 2 diabetes and their position in the current treatment algorithm].

    Science.gov (United States)

    Haluzík, Martin

    Insulin therapy has been for many years an inseparable part of the treatment of patients with type 2 diabetes, in particular those with longer diabetes duration. Current national and international guidelines list insulin treatment as a possible second choice therapy in patient with unsatisfactory glucose control on monotherapy with metformin. In reality, insulin therapy is often initiated later than it optimally should be. The reasons include among others the fear of patients and sometimes also of physicians from the side effects of insulin. Even though the options of antidiabetic treatment has been diversified by the addition of novel groups of antidiabetics with good efficacy and low risk of hypoglycemia, long acting insulin therapy still remains the most effective way of decreasing fasting hyperglycemia with the effect lasting further throughout the day. In this paper we summarize the current knowledge concerning long-acting insulins available on the Czech market or the ones that should be available in the near future. We discuss the differences among available long-acting insulins and their clinical consequences with respect to the selection of particular insulin for particular patient.Key words: biosimilar insulins - body weight - diabetes mellitus - hypoglycemia - long acting insulin.

    The development of a questionnaire to measure patients' and their parents' expectations before orthodontic treatment, and to test the reliability and validity of this measure. A two-stage methodology, with open-ended interviews to identify themes and concepts followed by development and testing of the questionnaire. GKT Orthodontic Department, King's College Dental Hospital. The sample consisted of 140 participants, 70 patients aged 12-14 years, who had been referred to the orthodontic department for treatment. One parent of each patient was also recruited. The study was in two phases. In the first phase 30 participants (15 new patients and their 15 parents) participated in open-ended interviews, which were analysed qualitatively. Information from these interviews was used to construct a questionnaire. During the second phase, the questionnaire was piloted on 10 participants, five new consecutive patients and their parents. The questionnaire was then distributed to 174 subjects (87 new patients and their 87 parents). Seventy-eight subjects (39 new patients and their 39 parents) completed the questionnaire before their orthodontic consultation. Another 96 subjects (48 new patients and their 48 parents) were invited to complete the questionnaire prior to and at their orthodontic consultation. Test-retest analysis was conducted on 22 participants (11 patients and their 11 parents), who completed the questionnaire previous to and at their orthodontic consultation, and contributed to the psychometric validation of this questionnaire. A questionnaire was devized using the key themes and concepts identified in the open-ended interviews. As a result, 10 questions, some with sub-questions were constructed using a visual analogue scale as the response format. The questionnaire developed had good face validity. Internal consistency of the questionnaire using Cronbach's alpha, produced an overall inter-item reliability > 0.7 along with item-total correlations > 0.3 in over 50

    Melatonin treatment has been reported to be capable of ameliorating metabolic diabetes-related abnormalities but also to cause hypogonadism in rats. We investigated whether the combined treatment with melatonin and insulin can improve insulin resistance and other metabolic disorders in rats with streptozotocin-induced diabetes during neonatal period and the repercussion of this treatment on the hypothalamic-pituitary-gonadal axis. At the fourth week of age, diabetic animals started an 8-wk treatment with only melatonin (0.2 mg/kg body weight) added to drinking water at night or associated with insulin (NHP, 1.5 U/100 g/day) or only insulin. Animals were then euthanized, and the subcutaneous (SC), epididymal (EP), and retroperitoneal (RP) fat pads were excised, weighed and processed for adipocyte isolation for morphometric analysis as well as for measuring glucose uptake, oxidation, and incorporation of glucose into lipids. Hypothalamus was collected for gene expression and blood samples were collected for biochemical assays. The treatment with melatonin plus insulin (MI) was capable of maintaining glycemic control. In epididymal (EP) and subcutaneous (SC) adipocytes, the melatonin plus insulin (MI) treatment group recovered the insulin responsiveness. In the hypothalamus, melatonin treatment alone promoted a significant reduction in kisspeptin-1, neurokinin B and androgen receptor mRNA levels, in relation to control group. Combined treatment with melatonin and insulin promoted a better glycemic control, improving insulin sensitivity in white adipose tissue (WAT). Indeed, melatonin treatment reduced hypothalamic genes related to reproductive function. Copyright © 2017. Published by Elsevier Inc.

    To compare treatment with metformin alone, metformin plus insulin and insulin alone in women with gestational diabetes (GDM). A total of 150 gestational diabetic patients who fulfilled the eligibility criteria were included in this prospective randomized control open labeled study. A risk factor based screening was done followed by a GCT and then local GTT criteria from antenatal clinics. They were initially divided into two groups with odd numbers assigned to metformin treatment and even numbers to insulin treatment. Metformin and/or insulin treatment was given and target blood sugar levels aimed at FBS ≤ 100 mg/dl and postprandial levels ≤ 126 mg/dl. Supplemental insulin was added to metformin treatment group to maintain the glycemic targets if required. Patients were followed until delivery and maternal fetal outcomes and pharmacotherapeutic characteristics were recorded on a performa. Less maternal weight gain was found in the metformin treated groups (9.8 ± 1.5 kg [metformin alone] vs. 9.8 ± 1.4 kg [metformin plus insulin] vs. 12.5 ± 1.1 kg [insulin alone] P metformin treated groups. There were no perinatal deaths in the study. Mean birth weight was significantly less in metformin treated groups (3.4 ± 0.4 kg vs. 3.3 ± 0.5 kg vs. 3.7 ± 0.5 kg P metformin groups. 42.7% of patients required supplemental insulin (mean dose of 13.6 ± 2 units) in the metformin group. Mean gestational age at which insulin was added was 31.8 ± 5.9 weeks. Metformin is an effective and cheap treatment option for women with gestational diabetes with or without supplemental insulin.

    Intranasal insulin delivery is currently being used in clinical trials to test for improvement in human memory and cognition, and in particular, for lessening memory loss attributed to neurodegenerative diseases. Studies have reported the effects of short-term intranasal insulin treatment on various behaviors, but less have examined long-term effects. The olfactory bulb contains the highest density of insulin receptors in conjunction with the highest level of insulin transport within the brain. Previous research from our laboratory has demonstrated that acute insulin intranasal delivery (IND) enhanced both short- and long-term memory as well as increased two-odor discrimination in a two-choice paradigm. Herein, we investigated the behavioral and physiological effects of chronic insulin IND. Adult, male C57BL6/J mice were intranasally treated with 5μg/μl of insulin twice daily for 30 and 60days. Metabolic assessment indicated no change in body weight, caloric intake, or energy expenditure following chronic insulin IND, but an increase in the frequency of meal bouts selectively in the dark cycle. Unlike acute insulin IND, which has been shown to cause enhanced performance in odor habituation/dishabituation and two-odor discrimination tasks in mice, chronic insulin IND did not enhance olfactometry-based odorant discrimination or olfactory reversal learning. In an object memory recognition task, insulin IND-treated mice did not perform differently than controls, regardless of task duration. Biochemical analyses of the olfactory bulb revealed a modest 1.3 fold increase in IR kinase phosphorylation but no significant increase in Kv1.3 phosphorylation. Substrate phosphorylation of IR kinase downstream effectors (MAPK/ERK and Akt signaling) proved to be highly variable. These data indicate that chronic administration of insulin IND in mice fails to enhance olfactory ability, object memory recognition, or a majority of systems physiology metabolic factors - as reported to

    Treatment persistence with basal insulins is crucial to achieving sustained glycemic control, which is associated with a reduced risk of microvascular disease and other complications of type 2 diabetes (T2D). However, studies suggest that persistence with basal insulin treatment is often poor. To measure and benchmark real-world basal insulin treatment persistence among patients with T2D across different payer segments in the United States. This was a retrospective observational study of data from a national pharmacy database (Walgreen Co., Deerfield, IL). The analysis included patients with T2D aged ≥ 18 years who filled ≥ 1 prescription for basal insulins between January 2013 and June 2013 (the index prescription) and who had also filled prescriptions for ≥ 1 oral antidiabetes drug in the database. Patients with claims for premixed insulin were excluded. Treatment persistence was defined as remaining on the study medication(s) during the 1-year follow-up period. Patients were stratified according to treatment history (existing basal insulin users vs. new insulin users), payer segments (commercially insured, Medicare, Medicaid, or cash-pay), type of basal insulin (insulin glargine, insulin detemir, or neutral protamine Hagedorn insulin [NPH]), and device for insulin administration (pen or vial/syringe). A total of 274,102 patients were included in this analysis, 82% of whom were existing insulin users. In terms of payer segments, 45.3% of patients were commercially insured, 47.8% had Medicare, 5.9% had Medicaid, and 1.1% were cash-pay. At the 1-year follow-up, basal insulin treatment persistence rate was 66.8% overall, 61.7% for new users, and 67.9% for existing users. In general, for both existing and new basal insulin users, higher persistence rate and duration were associated with Medicare versus cash-pay patients, use of insulin pens versus vial/syringe, and use of insulin glargine versus NPH. This large-scale study provides a benchmark of basal insulin

    Purpose: After treatment for early glottic cancer, a considerable number of patients end up with voice problems interfering with daily life activities. A 5-item screening questionnaire was designed for detection of voice impairment. The purpose of this study is to assess psychometric properties of this questionnaire in clinical practice. Methods and Materials: The questionnaire was completed by 110 controls without voice complaints and 177 patients after radiotherapy or laser surgery for early glottic cancer. Results: Based on normative data of the controls, a score of 5 or less on at least 1 of the 5 questions was considered to state overall voice impairment. Reliability of the questionnaire proved to be good. Voice impairment was reported in 44% of the patients treated with radiotherapy vs. 29% of the patients treated with endoscopic laser surgery. Conclusions: The questionnaire proved to be a reliable, valid, and feasible method to detect voice impairment in daily life. The questionnaire is easy to fill in, and interpretation is straightforward. It is useful for both radiation oncologists and otorhinolaryngologists in their follow-up of patients treated for early glottic cancer

    We aimed to review systematically the published evidence regarding the effect of questionnaire design on the recall of pharmacological treatments. The electronic databases Pubmed, EMBASE, and Cochrane Library were searched from inception to October 2007, using the following search terms: drug utilization, pharmaceutical preparations, pharmacoepidemiology, validation studies, methods, epidemiologic methods, interviews, data collection, and questionnaires. Drug utilization studies comparing different types of questionnaire or methods of questionnaire administration were included. Backward and forward citation tracking were also conducted. Eight studies were included in the systematic review, comparing questions asking for specific drugs or indications with open-ended questions (n = 5), evaluating the use of memory aids (n = 1), or studying the influence of response order on recall (n = 2). The studies were heterogeneous, namely regarding the populations evaluated (e.g., pregnant women, hypertensive patients, general population), mode of questionnaire administration (e.g., personal or telephone interview, self-administered), recall period (e.g., current use, 1 week, previous episode of a disease), or drugs evaluated (e.g., analgesics, antimalarials, all medicines). Despite the lack of standardization in presentation of results, the prevalence of drug use may vary between 5 and 40% when drug names and indications or pictures are used as memory aids, or as a result of primacy effects in self-administered questionnaires. The yielding of the questionnaires depended on the pharmacological groups evaluated. Scientific work regarding methods for drug utilization data collection is scarce. The available evidence highlights the importance of knowing the questionnaire characteristics for a proper interpretation of results from drug utilization studies. (c) 2009 John Wiley & Sons, Ltd.

    Full Text Available BackgroundThe Modality of Insulin Treatment Evaluation (MOTIV study was performed to provide real-world data concerning insulin initiation in Korean type 2 diabetes mellitus (T2DM patients with inadequate glycemic control with oral hypoglycemic agents (OHAs.MethodsThis multicenter, non-interventional, prospective, observational study enrolled T2DM patients with inadequate glycemic control (glycosylated hemoglobin [HbA1c] ≥7.0% who had been on OHAs for ≥3 months and were already decided to introduce basal insulin by their physician prior to the start of the study. All treatment decisions were at the physician's discretion to reflect real-world practice.ResultsA total of 9,196 patients were enrolled, and 8,636 patients were included in the analysis (mean duration of diabetes, 8.9 years; mean HbA1c, 9.2%. Basal insulin plus one OHA was the most frequently (51.0% used regimen. After 6 months of basal insulin treatment, HbA1c decreased to 7.4% and 44.5% of patients reached HbA1c <7%. Body weight increased from 65.2 kg to 65.5 kg, which was not significant. Meanwhile, there was significant increase in the mean daily insulin dose from 16.9 IU at baseline to 24.5 IU at month 6 (P<0.001. Overall, 17.6% of patients experienced at least one hypoglycemic event.ConclusionIn a real-world setting, the initiation of basal insulin is an effective and well-tolerated treatment option in Korean patients with T2DM who are failing to meet targets with OHA therapy.

    to verify the face validity, criterion-related validity and the reliability of two distinct forms of presentation of the instrument Measurement of Adherence to Treatment, one being for ascertaining the adherence to the use of oral antidiabetics and the other for adherence to the use of insulin, as well as to assess differences in adherence between these two modes of drug therapy. a methodological study undertaken with 90 adults with Type 2 Diabetes Mellitus. The criterion-related validity was verified using the Receiver Operating Characteristic curves; and for the reliability, the researchers calculated the Cronbach alpha coefficient, the item-total correlation, and the Pearson correlation coefficient. the oral antidiabetics and the other showed sensitivity of 0.84, specificity of 0.35 and a Cronbach correlation coefficient of 0.84. For the adherence to the use of insulin, the values found were, respectively, 0.60, 0.21 and 0.68. A statistically significant difference was found between the final scores of the two forms of the instrument, indicating greater adherence to the use of insulin than to oral antidiabetics. it is concluded that the two forms of the Measurement of Adherence to Treatment instrument are reliable and should be used to evaluate adherence to drug treatment among people with diabetes mellitus.

    This questionnaire study aimed to estimate the overall frequencies of positive perception towards orthodontic treatment among adults categorized according to age, sex, and area of living, and to identify barriers or negative perceptions preventing them from receiving orthodontic treatment. The participants included 598 adults aged over 20 years (230 men and 368 women) who visited the Dental Hospital of Seoul St. Mary's Hospital. The participants' opinions regarding their consideration of receiving orthodontic treatment were recorded using a specially designed questionnaire. The overall rate of positive perception towards orthodontic treatment was 48.5%. Compared to adults in their 20s (63.2%), those in their 40s and 50s had a lower percentage of interest in orthodontic treatment (46.2% and 45.1%, respectively; p orthodontic treatment. The middle-aged had a relatively high percentage of interest (above 45%) in orthodontic treatment. However, demographic characteristics were not significantly associated with the positive interest. These results highlight the need for educating the middle-aged about the limitations and possibilities of orthodontic treatment to increase its acceptance.

    Comparison of the effects of one year treatment with sibutramine compared to placebo on insulin resistance parameters, body weight, glycemic control, and lipid profile, in type 2 diabetic patients. Two hundred and forty-six patients with uncontrolled type 2 diabetes mellitus in therapy with different oral hypoglycemic agents or insulin were enrolled in this study and randomised to take sibutramine 10 mg or placebo for one year. We evaluated at baseline, and after 3, 6, 9, and 12 months these parameters: homeostasis model assessment insulin resistance index (HOMA-IR), retinol binding protein-4 (RBP-4), resistin, visfatin, and high sensitivity-C reactive protein (Hs-CRP), body weight, body mass index (BMI), glycated hemoglobin (HbA(₁c)), fasting plasma glucose (FPG), post-prandial plasma glucose (PPG), fasting plasma insulin (FPI), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), and triglycerides (T(g)). A faster decrease of HOMA-IR, resistin, and RBP-4 was recorded with sibutramine compared to the control group. We observed a significant decrease of Hs-CRP in both groups, and a faster improvement of HbA(₁c), FPG and PPG with sibutramine compared to the control group; furthermore we recorded a decrease of FPI, TC, LDL-C, body weight, and BMI in the sibutramine group, but not in the control group. Sibutramine gave a faster improvement of insulin resistance parameters and glycemic control compared to placebo; furthermore sibutramine gave also an improvement of lipid profile, and body weight.

    Context: An extensive body of literature indicates a relationship between insulin resistance and the up-regulation of the kynurenine pathway, i.e. the preferential conversion of tryptophan to kynurenine, with subsequent overproduction of diabetogenic downstream metabolites, such as kynurenic acid. Case description: We have measured the concentration of kynurenine pathway metabolites (kynurenines) in the brain and pancreas of two young (27 and 28 yrs) insulin resistant, normoglycemic subjects (M-values 2 and 4 mg/kg/min, respectively) using quantitative C-11-alpha-methyl-tryptophan PET/CT imaging. Both subjects underwent a preventive 12-week metformin treatment regimen (500 mg daily) prior to the PET/CT study. Whereas treatment was successful in one of the subject (M-value increased from 2 to 12 mg/kg/min), response was poor in the other subjects (M-value changed from 4 to 5 mg/kg/min). Brain and pancreas concentrations of kynurenines observed in the responder were similar to that in a healthy control subject, whereas kynurenines determined in the non-responder were about 25% higher and similar to those found in a severely insulin resistant patient. Consistent with this outcome, M-values were negatively correlated with both kynurenic acid levels (R 2  = 0.68, p = 0.09) as well as with the kynurenine to tryptophan ratio (R 2  = 0.63, p = 0.11). Conclusion: The data indicates that kynurenine pathway metabolites are increased in subjects with insulin resistance prior to overt manifestation of hyperglycemia. Moreover, successful metformin treatment leads to a normalization of tryptophan metabolism, most likely as a result of decreased contribution from the kynurenine metabolic pathway.

    It was uncertain whether an algorithm that involves increasing insulin dosages by 1 unit/day may cause more hypoglycemia with the longer-acting insulin glargine 300 units/mL (GLA-300). The objective of this study was to compare safety and efficacy of 2 titration algorithms, INSIGHT and EDITION, for GLA-300 in people with uncontrolled type 2 diabetes mellitus, mainly in a primary care setting. This was a 12-week, open-label, randomized, multicentre pilot study. Participants were randomly assigned to 1 of 2 algorithms: they either increased their dosage by 1 unit/day (INSIGHT, n=108) or the dose was adjusted by the investigator at least once weekly, but no more often than every 3 days (EDITION, n=104). The target fasting self-monitored blood glucose was in the range of 4.4 to 5.6 mmol/L. The percentages of participants reaching the primary endpoint of fasting self-monitored blood glucose ≤5.6 mmol/L without nocturnal hypoglycemia were 19.4% (INSIGHT) and 18.3% (EDITION). At week 12, 26.9% (INSIGHT) and 28.8% (EDITION) of participants achieved a glycated hemoglobin value of ≤7%. No differences in the incidence of hypoglycemia of any category were noted between algorithms. Participants in both arms of the study were much more satisfied with their new treatment as assessed by the Diabetes Treatment Satisfaction Questionnaire. Most health-care professionals (86%) preferred the INSIGHT over the EDITION algorithm. The frequency of adverse events was similar between algorithms. A patient-driven titration algorithm of 1 unit/day with GLA-300 is effective and comparable to the previously tested EDITION algorithm and is preferred by health-care professionals.

    Full Text Available We report a rare case of severe hypoglycemia after sunitinib treatment for pancreatic neuroendocrine carcinoma. We describe the initial clinical presentation, laboratory results, pathologic findings, and managment in a patient with a nonfunctioning pancreatic neuroendocrine carcinoma with liver metastases who developed life threatening hypoglycemia after 2 months of sunitinib therapy. A 46-year-old woman presented to the emergency department with loss of consciousness from hypoglycemia. Serum C-peptide and insulin levels at fasting state revealed that the hypoglycemia resulted from endogenous hyperinsulinemia. She had been diagnosed with nonfunctioning pancreatic neuroendocrine carcinoma based on a biopsy of metastatic cervical lymph node and was being treated with sunitinib, a small molecule tyrosine kinase inhibitor. Immunohistochemical stain of the metastatic liver mass demonstrated that the initially nonfunctioning neuroendocrine carcinoma cells had changed into insulin-producing cells after sunitinib therapy. Transarterial chemoembolization of the liver masses and systemic chemotherapy with streptozotocin/adriamycin relieved the hypoglycemia. A nonfunctioning pancreatic neuroendocrine carcinoma was transformed into an insulin-producing tumor after treatment with sunitinib, causing endogenous hyperinsulinemia and severe hypoglycemia.

    The aim of our study was to compare the responsiveness of the Hand10 questionnaire and the Pain visual analogue scale (VAS) for the assessment of lateral epicondylitis. The standardized response mean and effect size were used as indicators of responsiveness, measured at baseline and after 6 months of treatment. Among the 54 patients enrolled, 28 were treated using a forearm band, compress and stretching, with the other 26 patients treated using compress and stretching. The standardized response mean and the effect size were 1.18 and 1.38, respectively, of the Hand10 and 1.39 and 1.75, respectively, for the Pain VAS. The responsiveness of both tests was considered to be large, based on Cohen's classification of effect size, supporting the use of the Hand10 questionnaire to assess treatment outcomes for lateral epicondylitis.

    Full Text Available Objective: We aimed to demonstrate the approaches of physicians with a questionnaire toward the patients with pulmonary thromboembolism (PTE in our country. Methods: An invitation letter including a questionnaire with 28 questions to assess the approaches they prefer in the patients with PTE and the capabilities of the departments they work at and a link for the questionnaire was directed to the mail groups of chest diseases specialists. Responses of the physicians who participated in the questionnaire were reviewed. Results: The examinations used to diagnose PTE such as D-dimer, troponin, echocardiographic Doppler ultrasonography and multidetector computed tomography (CT have been performed in 94% of the institutions, ventilation/perfusion scintigraphy, MRI and pulmonary angiography examinations were performed in 50% of the instututions. While D-dimer test was performed in 73.2% of the institutions by quantitative ELISA; in 15.7% of them it was semiquantitative and in 11.6% of the instutitions it was performed by latex agglutination. 81% of physicians were seen to be using clinical probability scoring systems and most commonly used scoring method was seen to be Wells scoring with a rate of 90%. According to the simplified PESI score, 61.5% of the physicians reported to prefer outpatient treatment. In non-massive and submassive pulmonary thromboemboli patients, 86.2% of the physicians reported to prefer thr low molecular weight heparin (LMWH treatment; vitamin K antagonist in maintenance treatment was also the most commonly resorted drug with a percentage of 84.9. Conclusion: The absence of the examinations used in the diagnosis and treatment of PTE in most institutions and difficulty to reach the available examinations at all hours of the day were significant facts. Especially; lack of access to high-sensitivity D-dimer test, bedside echocardiography used to assess right ventricular dysfunction, troponin and NT-proBNP makes us think about low

  17. PEDF expression is inhibited by insulin treatment in adipose tissue via suppressing 11β-HSD1.

    Directory of Open Access Journals (Sweden)

    Yinli Zhou

    Full Text Available Early intensive insulin therapy improves insulin sensitivity in type 2 diabetic patients; while the underlying mechanism remains largely unknown. Pigment epithelium-derived factor (PEDF, an anti-angiogenic factor, is believed to be involved in the pathogenesis of insulin resistance. Here, we hypothesize that PEDF might be down regulated by insulin and then lead to the improved insulin resistance in type 2 diabetic patients during insulin therapy. We addressed this issue by investigating insulin regulation of PEDF expression in diabetic conditions. The results showed that serum PEDF was reduced by 15% in newly diagnosed type 2 diabetic patients after insulin therapy. In adipose tissue of diabetic Sprague-Dawley rats, PEDF expression was associated with TNF-α elevation and it could be decreased both in serum and in adipose tissue by insulin treatment. In adipocytes, PEDF was induced by TNF-α through activation of NF-κB. The response was inhibited by knockdown and enhanced by over expression of NF-κB p65. However, PEDF expression was indirectly, not directly, induced by NF-κB which promoted 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1 expression in adipocytes. 11β-HSD1 is likely to stimulate PEDF expression through production of active form of glucocorticoids as dexamethasone induced PEDF expression in adipose tissue. Insulin inhibited PEDF by down-regulating 11β-HSD1 expression. The results suggest that PEDF activity is induced by inflammation and decreased by insulin through targeting 11β-HSD1/glucocorticoid pathway in adipose tissue of diabetic patients.

  18. Is insulin the preferred treatment for HbA1c >9%?

    The algorithms and guidelines of the American Association of Clinical Endocrinologists and the American Diabetes Association recommend that insulin administration be strongly considered for people with type 2 diabetes (T2D) with HbA1c levels exceeding 9.0% and 10%, respectively. Although the caveat is given in both sets of recommendations that this is particularly appropriate when patients are "symptomatic," referring to urinary frequency with increased thirst and appetite, weight loss, and ketosis, the clinical definition of such presentations may be ill-defined, and it is noteworthy that both documents consider insulin to offer particular benefit under such circumstances. However, with multiple options for glycemic treatment, it is of interest to reconsider this argument for insulin use. It should be recalled that in the UK Prospective Diabetes Study, diet alone was associated with a reduction in HbA1c from 9% to 7%. Drug-naïve people with T2D do often show surprisingly strong reductions in HbA1c with metformin-based dual-agent oral treatment approaches; a recent report showed that even with baseline HbA1c >11%, the combination of metformin with a sulfonylurea, pioglitazone, or sitagliptin was associated with reduction in HbA1c from 11.6% to 6.0%. A 32-week study of the combination of rosiglitazone with metformin in patients with mean baseline HbA1c 8.9% showed a mean HbA1c reduction of 2.3%, and an open-label cohort with baseline HbA1c 11.8% had a reduction in HbA1c to 7.8%. With metformin plus sitagliptin, a mean placebo-adjusted HbA1c reduction of 2.1% from a baseline of 8.8% was reported, with those patients with baseline HbA1c >9% having a 2.6% reduction in HbA1c, and an open-label cohort with baseline HbA1c 11.2% having a 2.9% reduction in HbA1c. Similar 2% HbA1c reductions from baseline levels of 9.1% were seen with metformin in initial combination with the sodium-glucose cotransporter 2 (SGLT2) inhibitor dapagliflozin. Although such dual oral agent

    To assess the influence of health locus of control and fear of hypoglycaemia on metabolic control and treatment satisfaction in people with Type 1 diabetes mellitus on continuous subcutaneous insulin infusion. People with Type 1 diabetes on continuous subcutaneous insulin infusion for at least 1 year, sub-classified as an 'acceptable glucose control' group [HbA 1c ≤ 58 mmol/mol (7.5%)] and a 'suboptimum glucose control' group [HbA 1c > 58 mmol/mol (7.5%)], were consecutively enrolled in a multicentre cross-sectional study. Questionnaires were administered to assess health locus of control [Multidimensional Health Locus of Control (MHLC) scale, with internal and external subscales], fear of hypoglycaemia [Hypoglycaemia Fear Survey II (HFS-II)] and treatment satisfaction [Diabetes Treatment Satisfaction Questionnaire (DTSQ)]. We enrolled 214 participants (mean ± sd age 43.4 ± 12.1 years). The suboptimum glucose control group (n = 127) had lower mean ± sd internal MHLC and DTSQ scores than the acceptable glucose control group (19.6 ± 5.2 vs 21.0 ± 5.0, P = 0.04 and 28.8 ± 4.8 vs 30.9 ± 4.5, P locus represents the most important locus of control pattern for achieving good metabolic control. © 2017 Diabetes UK.

    Full Text Available Abstract Background The 'Perception of Anti-Coagulant Treatment Questionnaire' (PACT-Q was developed to assess patients' expectations of, and satisfaction with their anticoagulant treatment. This questionnaire needs to be finalised and psychometrically validated. Methods The PACT-Q was included in the United States, the Netherlands and France into three phase III multinational clinical trials conducted to evaluate efficacy and safety of a new long-acting anticoagulant drug (idraparinux compared to vitamin K antagonist (VKA. PACT-Q was administered to patients with deep venous thrombosis (DVT, atrial fibrillation (AF or pulmonary embolism (PE at Day 1, to assess patients' expectations, and at 3 and 6 months to assess patients' satisfaction and treatment convenience and burden. The final structure of the PACT-Q (Principal Component Analysis – PCA – with Varimax Rotation was first determined and its psychometric properties were then measured with validity of the structure (Multitrait analysis, internal consistency reliability (Cronbach's alpha coefficients and known-group validity. Results PCA and multitrait analyses showed the multidimensionality of the "Treatment Expectations" dimension, comprising 7 items that had to be scored independently. The "Convenience" and "Burden of Disease and Treatment" dimensions of the hypothesised original structure of the questionnaire were combined, thus resulting in 13 items grouped into the single dimension "Convenience". The "Anticoagulant Treatment Satisfaction" dimension remained unchanged and included 7 items. All items of the "Convenience" and "Anticoagulant Treatment Satisfaction" dimensions displayed good convergent and discriminant validity. The internal consistency reliability was good, with a Cronbach's alpha of 0.84 for the "Convenience" dimension, and 0.76 for the "Anticoagulant Treatment Satisfaction" dimension. Known-group validity was good, especially with regard to occurrence of

    Full Text Available Objective: Obesity-associated impaired fat accumulation in the visceral adipose tissue can lead to ectopic fat deposition and increased risk of insulin resistance and type 2 diabetes mellitus (T2DM. This study investigated whether impaired adipogenesis of omental (OM adipose tissues and elevated 4-hydroxynonenal (4-HNE accumulation contribute to this process, and if combined metformin and insulin treatment in T2DM patients could rescue this phenotype. Methods: OM adipose tissues were obtained from forty clinically well characterized obese individuals during weight reduction surgery. Levels of 4-HNE protein adducts, adipocyte size and number of macrophages were determined within these tissues by immunohistochemistry. Adipogenic capacity and gene expression profiles were assessed in preadipocytes derived from these tissues in relation to insulin resistance and in response to 4-HNE, metformin or combined metformin and insulin treatment. Results: Preadipocytes isolated from insulin resistant (IR and T2DM individuals exhibited lower adipogenesis, marked by upregulation of anti-adipogenic genes, compared to preadipocytes derived from insulin sensitive (IS individuals. Impaired adipogenesis was also associated with increased 4-HNE levels, smaller adipocytes and greater macrophage presence in the adipose tissues. Within the T2DM group, preadipocytes from combined metformin and insulin treated subset showed better in vitro adipogenesis compared to metformin alone, which was associated with less presence of macrophages and 4-HNE in the adipose tissues. Treatment of preadipocytes in vitro with 4-HNE reduced their adipogenesis and increased proliferation, even in the presence of metformin, which was partially rescued by the presence of insulin. Conclusion: This study reveals involvement of 4-HNE in the impaired OM adipogenesis-associated with insulin resistance and T2DM and provides a proof of concept that this impairment can be reversed by the synergistic

    The patient, a 24-year-old man, had suffered from hunger, sweating, tachycardia and palpitation for three years. He was diagnosed as having Graves' disease (GD) and treated with methimazole (MMI) for 3 months. He noted that palpitation and perspiration seemed to particularly occur when he was hungry, and thus he was examined to determine whether these symptoms were caused by hypoglycemia. As a markedly elevated immunoreactive insulin level and the presence of insulin antibody in serum were found, he was diagnosed as having insulin autoimmune syndrome (IAS). HLA typing revealed the patient to be positive for group Bw62/Cw4/DR4, which is reportedly a specific HLA type in MMI-treated euthyoroid GD patients with IAS. In spite of the continuation of MMI treatment, the % binding of IRI decreased and the hypoglycemic episode disappeared. In contrast to the previously reported MMI induced IAS in GD cases, MMI is unlikely to have exacerbated IAS in the present case, although his HLA combination is identical to that of the previous cases.

    The prevalence of type 2 diabetes is rapidly increasing, with severe socioeconomic impacts. Excess lipid deposition in peripheral tissues impairs insulin sensitivity and glucose uptake, and has been proposed to contribute to the pathology of type 2 diabetes. However, few treatment options exist that directly target ectopic lipid accumulation. Recently it was found that vascular endothelial growth factor B (VEGF-B) controls endothelial uptake and transport of fatty acids in heart and skeletal muscle. Here we show that decreased VEGF-B signalling in rodent models of type 2 diabetes restores insulin sensitivity and improves glucose tolerance. Genetic deletion of Vegfb in diabetic db/db mice prevented ectopic lipid deposition, increased muscle glucose uptake and maintained normoglycaemia. Pharmacological inhibition of VEGF-B signalling by antibody administration to db/db mice enhanced glucose tolerance, preserved pancreatic islet architecture, improved β-cell function and ameliorated dyslipidaemia, key elements of type 2 diabetes and the metabolic syndrome. The potential use of VEGF-B neutralization in type 2 diabetes was further elucidated in rats fed a high-fat diet, in which it normalized insulin sensitivity and increased glucose uptake in skeletal muscle and heart. Our results demonstrate that the vascular endothelium can function as an efficient barrier to excess muscle lipid uptake even under conditions of severe obesity and type 2 diabetes, and that this barrier can be maintained by inhibition of VEGF-B signalling. We propose VEGF-B antagonism as a novel pharmacological approach for type 2 diabetes, targeting the lipid-transport properties of the endothelium to improve muscle insulin sensitivity and glucose disposal.

They consisted of specialists authorized by the Japanese Society of Allergology and councillors of the society who were treating patients with bronchial asthma. Of the total of 306 (52% respondents, 241 replied to questions relating to adult asthma and 129 to questions relating to childhood asthma (including duplicate replies. For acute treatment, methods most commonly selected by physicians were, in increasing order of popularity, for adults: parenteral aminophylline, oxygen inhalation, parenteral steroids and parenteral adrenaline; for schoolchildren (6–16 years: parenteral aminophylline, inhaled β-stimulant, oxygen inhalation, inhaled β-stimulant + disodium cromoglycate (DSCG, parenteral steroids; and for infants (≤5 years: inhaled β-stimulant, parenteral aminophylline, oxygen inhalation, inhaled β-stimulant + DSCG and parenteral steroids. For maintenance treatment, methods most commonly selected by physicians were, in increasing order of popularity, for adults: oral administration of sustained-release theophylline, inhaled steroids and DSCG inhalation; for schoolchildren (6–16 years: DSCG inhalation, oral administration of sustained-release theophylline, oral administration of antiallergic agent preparation and (β-stimulant + DSCG inhalant; and for infants: DSCG inhalation, oral administration of sustained-release theophylline, oral administration of antiallergicagent preparation and β-stimulant + DSCG inhalant. The questionnaire results clearly showed that different drugs were selected for the treatment of asthma in adults, schoolchildren and infants.

    Objective: To study the magnitude of insulin-mediated airway hyper-reactivity and to explore the protective effects of salbutamol in inhibiting the insulin-induced airway hyper-responsiveness on tracheal smooth muscle of guinea pigs in vitro. Methods: The quasi-experimental study was conducted at the Pharmacology Department of Army Medical College, Rawalpindi, in collaboration with the Centre for Research in Experimental and Applied Medicine from December 2011 to July 2012. It used 18 healthy Dunkin Hartely guinea pigs of either gender. Effects of increasing concentrations of histamine (10-8-10-3M), insulin (10-8-10-3 M) and insulin pre-treated with salbutamol (10-6 M) were observed on isolated tracheal strip of guinea pig in vitro by constructing cumulative concentration response curves. The tracheal smooth muscle contractions were recorded with Transducer on Four Channel Oscillograph. Mean and standard error of mean were calculated. SPSS 16 was used for statistical analysis. Results: Histamine and insulin produced a concentration-dependent reversible contraction of isolated tracheal muscle of guinea pig. The mean of maximum amplitudes of contraction with histamine, insulin and insulin pre-treated with salbutamol were 92. 1.20 mm, 35+-1.13 mm and 14.55+-0.62 mm respectively. Salbutamol shifted the concentration response curve of insulin to the right and downwards. Conclusions: Salbutamol significantly reduced the insulin mediated airway hyper-reactivity in guinea pigs, suggesting that pre-treatment of inhaled insulin with salbutamol may have clinical implication in the amelioration of its potential respiratory adverse effects such as bronchoconstriction.

    Over the past few decades, continuous progress has been made in the development of insulin therapy. Basal insulins were developed around 60 years ago. However, existing basal insulins were found to have limitations. An ideal basal insulin should have the following properties viz. longer duration of action, a flat time-action profile, low day-to-day glycaemic variability, and the potential for flexible dosing. Basal insulins have advanced over the years, from lectin and neutral protamine Haged...

    in insulin requirements during pregnancy necessitate short-acting insulins for postprandial control of hyperglycemia. The fast-acting insulin analogue insulin aspart has been tested in a large, randomized trial of pregnant women with Type 1 diabetes and offers benefits in control of postprandial...... hyperglycemia with a tendency towards fewer episodes of severe hypoglycemia compared with human insulin. Treatment with insulin aspart was associated with a tendency toward fewer fetal losses and preterm deliveries than treatment with human insulin. Insulin aspart could not be detected in the fetal circulation...... and no increase in insulin antibodies was found. Thus, the use of insulin aspart in pregnancy is regarded safe....

    In the context of quality assurance, increasing demands are placed on the whole radiotherapy treatment process. The patients directly concerned generally do not realize most aspects of the quality assurance program (e.g., additional safety checks) during their daily therapy. It was the aim of this study to systematically ask patients about potential improvements during the course of radiotherapy treatment from their own perspective. In the defined time span (1 month), 624 radiotherapy patients (600 questionnaires were returned, 96.2%) were interviewed using a questionnaire newly developed to inquire about several aspects of their treatment. Furthermore, they were asked for their specific needs and suggestions for improvements that could be made during the course of radiotherapy treatment. Overall, the patients were satisfied with the course of their radiotherapy treatment and with patient care. As an example, about 90% agreed with the statement: ''My first contact with the radiation oncology unit proceeded with kindness and competence so that I was given the impression that I will be well cared for in this clinic.'' Considering the organization of the course of radiotherapy, a large majority of patients attached great value to set appointments for the therapy fractions. A main point of criticism was waiting times or delays caused by servicing or machine failures. Small, low cost improvements as music in the therapy room were considered as important as expensive measures (e.g., daylight in the therapy room). The patients emphasized the importance of staff friendliness. The situation of radiotherapy patients was, in general, satisfactory. Future improvements can be mainly expected from smooth organisation of both planning and treatment which can be achieved by electronic scheduling systems. Many results of the survey could be easily implemented in daily practice. In matters of organization radiation oncology with its complex procedures can be used as a model for

    The growth hormone-IGF (insulin-like growth factor) system plays a central role in hormonal growth regulation. Recombinant human (rh) growth hormone (GH) has been available since the late 1980s for replacement therapy in GH-deficient patients and for the stimulation of growth in patients with short stature of various causes. Growth promotion by GH occurs in part indirectly through the induction of IGF-1 synthesis. In primary disturbances of IGF-1 production, short stature can only be treated with recombinant human IGF-1 (rhIGF-1). rhIGF-1 was recently approved for this indication but can also be used to treat other conditions. Selective review of the literature on IGF-1 therapy, based on a PubMed search. In children with severe primary IGF-1 deficiency (a rare condition whose prevalence is less than 1:10,000), the prognosis for final height is very poor (ca. 130 cm), and IGF-1 therapy is the appropriate form of pathophysiologically based treatment. There is no alternative treatment at present. The subcutaneous administration of IGF-1 twice daily in doses of 80 to 120 microg/kg accelerates growth and increases final height by 12 to 15 cm, according to current data. There is, however, a risk of hypoglycemia, as IGF-1 has an insulin-like effect. As treatment with IGF-1 is complex, this new medication should only be prescribed, for the time being, by experienced pediatric endocrinologists and diabetologists.

    Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility in United States, affecting 6-10% of females in the reproductive age group. Recent studies have shown that insulin resistance plays an important role in the pathogenesis of PCOS. Traditionally, management of PCOS consisted mainly of ovulation induction, treatment of acne and hirsutism, and prevention of endometrial cancer. However, with mounting evidence showing that PCOS is associated with dysmetabolic syndrome and an increased risk for developing diabetes and heart disease, this can no longer be our sole focus. Current data support a strong recommendation that women with PCOS should undergo comprehensive evaluation for diabetes and recognized cardiovascular risk factors and receive appropriate treatment as needed. Lifestyle modifications remain the first-line therapy for all obese women with PCOS. However, many obese women with PCOS find weight loss difficult to achieve and maintain, and this is not an option for lean women with PCOS. For these reasons, insulin-sensitizing drugs are proving to be a promising and unique therapeutic option for chronic treatment of PCOS.

    Treatment adherence in hemodialysis is important for guaranteeing better results for patients, but Brazil still lacks validated assessment tools for this purpose. The current study aimed to perform a cross-cultural adaptation of the Renal Adherence Behaviour Questionnaire (RABQ) and the Renal Adherence Attitudes Questionnaire (RAAQ). The two questionnaires were submitted to the following cross-cultural adaptation procedures: translation, back-translation, expert panel review, and pilot study. Changes were made in the items' wording and application, which requires a face-to-face interview. It was not necessary to change the choices of answers. The Brazilian versions of the RABQ and RAAQ showed semantic and cultural equivalence to the original versions and are easy for the target population to understand. The two scales still require validity and reliability studies before use in the field.

This article reviews the available literature on the pharmacology, efficacy and safety of BIAsp 30 in T1DM and T2DM from an online search of the PubMed database. Following injection, BIAsp 30 reaches higher plasma insulin levels more quickly than human premix or basal insulin, giving effective reduction of postprandial hyperglycemia. In T1DM patients, randomized controlled trials (RCTs have shown that HbA1c reduction is similar, but postprandial glycemic control is better, with BIAsp 30 than with human insulin regimens. In T2DM patients, lowering of HbA1c and postprandial hyperglycemia with BIAsp 30 compare favorably with optimized oral antidiabetes drug treatment, insulin glargine, and, in obese patients, human premix. An increase in minor hypoglycemia with BIAsp 30 relative to basal insulin has been reported in T2DM patients, but major and nocturnal hypoglycemia rates are generally low. Findings from RCTs in T2DM patients are supported by large observational studies. In summary, BIAsp 30 once to three times daily represents a simple and effective tool for the modern management of diabetes.Keywords: biphasic insulin aspart, BIAsp 30, premix, type 1 diabetes, type 2 diabetes

    Full Text Available Introduction: Insulin therapy is the most commonly used treatment for controlling hyperglycemia after coronary artery bypass surgery in both diabetic and nondiabetic patients. Metformin has been indicated for critically ill patients as an alternate for the treatment of hyperglycemia. This study evaluated the effect of metformin and insulin in hyperglycemia treatment after coronary artery bypass surgery in nondiabetic patients. Settings and Design: This study was a clinical trial comprising nondiabetic patients who had undergone coronary artery bypass surgery. Patients were randomly divided into the insulin group and the metformin group. Methods: Patients in the insulin group received continuous infusion of insulin while those in the metformin group received 500 mg metformin tablets twice daily. All the patients were followed up for 3 days after stabilization of blood glucose levels. Statistical Analysis: Data were analyzed using Chi-square test and Mann–Whitney U-test. Results: This study included a total of 56 patients. During the study period, the mean blood glucose levels decreased from 225.24 to 112.36 mg/dl (↓112.88 mg/dl in the insulin group and from 221.80 to 121.92 mg/dl in the metformin group (↓99.88 mg/dl. There was no significant difference in the blood glucose levels of the patients between the two groups at any measurement times (P > 0.05. Conclusion: Using 500 mg metformin twice daily is similar to using insulin in nondiabetic patients undergoing coronary artery bypass graft. Therefore, the use of metformin can be considered as a treatment strategy for controlling hyperglycemia in this group of patients.

    Women with polycystic ovary syndrome (PCOS) diagnosed with hyperandrogenism and ovulatory dysfunction have an increased risk of developing metabolic disorders, including type 2 diabetes and cardiovascular disease. We previously developed a model that uses letrozole to elevate endogenous testosterone levels in female mice. This model has hallmarks of PCOS, including hyperandrogenism, anovulation, and polycystic ovaries, as well as increased abdominal adiposity and glucose intolerance. In the current study, we further characterized the metabolic dysfunction that occurs after letrozole treatment to determine whether this model represents a PCOS-like metabolic phenotype. We focused on whether letrozole treatment results in altered pancreatic or liver function as well as insulin resistance. We also investigated whether hyperinsulinemia occurs secondary to weight gain and insulin resistance in this model or if it can occur independently. Our study demonstrated that letrozole-treated mice developed hyperinsulinemia after 1 week of treatment and without evidence of insulin resistance. After 2 weeks of letrozole treatment, mice became significantly heavier than placebo mice, demonstrating that weight gain was not required to develop hyperinsulinemia. After 5 weeks of letrozole treatment, mice exhibited blunted glucose-stimulated insulin secretion, insulin resistance, and impaired insulin-induced phosphorylation of AKT in skeletal muscle. Moreover, letrozole-treated mice exhibited dyslipidemia after 5 weeks of treatment but no evidence of hepatic disease. Our study demonstrated that the letrozole-induced PCOS mouse model exhibits multiple features of the metabolic dysregulation observed in obese, hyperandrogenic women with PCOS. This model will be useful for mechanistic studies investigating how hyperandrogenemia affects metabolism in females. Copyright © 2017 Endocrine Society.

    Insulin charts represent a key component in the inpatient glycemic management process. The aim was to evaluate the quality of structure, documentation, and treatment of diabetic inpatient care to design a new standardized insulin chart for a large university hospital setting. Historically grown blank insulin charts in use at 39 general wards were collected and evaluated for quality structure features. Documentation and treatment quality were evaluated in a consecutive snapshot audit of filled-in charts. The primary end point was the percentage of charts with any medication error. Overall, 20 different blank insulin charts with variable designs and significant structural deficits were identified. A medication error occurred in 55% of the 102 audited filled-in insulin charts, consisting of prescription and management errors in 48% and 16%, respectively. Charts of insulin-treated patients had more medication errors relative to patients treated with oral medication (P international standards, a new insulin chart was developed to overcome these quality hurdles.

    Intensive insulin treatment of critically ill patients was seen as a promising method of treatment, though recent studies showed that reducing the blood glucose level below 6 mmol/l had a detrimental outcome. The mechanisms of the effects of insulin in the critically ill are not completely understood. The purpose of the study was to test the hypothesis that intensive insulin treatment may influence forearm blood flow independently of global hemodynamic indicators. The study encompassed 29 patients of both sexes who were admitted to the intensive care unit due to sepsis and required artificial ventilation as the result of acute respiratory failure. 14 patients were randomly selected for intensive insulin treatment (Group 1; blood glucose concentration 4.4-6.1 mmol/l), and 15 were selected for conventional insulin treatment (Group 2; blood glucose level 7.0 mmol/l-11.0 mmol/l). At the start of the study (t0, beginning up to 48 hours after admittance and the commencement of artificial ventilation), at 2 hours (t1), 24 hours (t2), and 72 hours (t3) flow in the forearm was measured for 60 minutes using the strain-gauge plethysmography method. Student's t-test of independent samples was used for comparisons between the two groups, and Mann-Whitney's U-test where appropriate. Linear regression analysis and the Pearson correlation coefficient were used to determine the levels of correlation. The difference in 60-minute forearm flow at the start of the study (t0) was not statistically significant between groups, while at t2 and t3 significantly higher values were recorded in Group 1 (t2; Group 1: 420.6 +/- 188.8 ml/100 ml tissue; Group 2: 266.1 +/- 122.2 ml/100 ml tissue (95% CI 30.9-278.0, P = 0.02); t3; Group 1: 369.9 +/- 150.3 ml/100 ml tissue; Group 2: 272.6 +/- 85.7 ml/100 ml tissue (95% CI 5.4-190.0, P = 0.04). At t1 a trend towards significantly higher values in Group 1 was noted (P = 0.05). The level of forearm flow was related to the amount of insulin infusion (r

    Full Text Available Objectives: To evaluate the knowledge of ophthalmologists regarding local anesthesia toxicity syndrome (LATS and intravenous lipid emulsion used in treatment, and to raise awareness of this issue. Materials and Methods: A questionnaire comprising 14 questions about demographics, local anesthesia (LA use, toxicity, and treatment methods was administered to ophthalmologists at different hospitals. Results: The study included 104 ophthalmologists (25% residents, 67.3% specialists, 7.7% faculty members with a mean age of 35.71±6.53 years. The highest number of participants was from state hospitals (65.4%, and 34.6% of the physicians had been working in ophthalmology for more than 10 years. Seventy-six percent of the participants reported using LA every day or more than twice a week, but 56.7% had received no specific training on this subject. No statistically significant difference was observed between different education levels and the rates of training (p=0.419. Bupivacaine was the most preferred LA and the majority of respondents (97.1% did not use a test dose. Allergy (76% and hypotension (68.3% were the most common responses for early findings of LATS, while cardiac arrest (57.4% and hepatotoxicity (56.4% were given for late findings. The most common responses concerning the prevention of LATS included monitorization (72.4% and use of appropriate doses (58.2%. Symptomatic treatment was selected by 72.4% of respondents and cardiopulmonary resuscitation and antihistamine treatment by 58.8%. Of the ophthalmologists in the study, 62.5% had never encountered LATS. The use of 20% intravenous lipid emulsion therapy for toxicity was known by 65% of the physicians, but only 1 participant stated having used it previously. Conclusion: The importance of using 20% lipid emulsion in LATS treatment and having it available where LA is administered must be emphasized, and there should be compulsory training programs for ophthalmologists on this subject.

    Full Text Available Aims To study the time and costs of insulin treatment of newly registered outpatients with Type 2 diabetes mellitus (T2DM. Methods In total, 355 patients with T2DM were registered on their first visit to one of 11 diabetes clinics across Japan. Of these, 313 were not being treated with insulin (the non-insulin group, whereas 42 were (the insulin group. In the insulin group, 26 were already on insulin at the first visit, whereas 16 were started on insulin after their first visit. The time and costs involved in the care were recorded over the following 5 months. Results In the first 3 months, considerable time was expended in both groups, with the time spent by physicians a little (but significantly longer for the insulin group. The total time expended by all care providers was approximately 1.3-fold greater for the insulin compared with the non-insulin group. The total cost and total cost/min for the insulin group was almost twice that for the non-insulin group. Over the 5-month period, mean HbA 1c in the non-insulin group improved from 8.0% to 6.5%, with 72% achieving a glycemic target of HbA 1c ≤ 6.5%. In contrast, in the insulin group, mean HbA 1c improved from 9.4% to 7.6%, with only 39% achieving the target. There were no reports of major hypoglycemic events in either group and body mass index remained stable. Conclusions The insulin therapy for T2DM can be achieved safely and effectively at outpatient clinics, even though it requires considerably more time and resources than non-insulin therapy.

    In this study, we review the efficacy and safety limitations of insulin-dependent oral antidiabetic agents. In terms of efficiency, the main drawback of metformin, sulfonylureas, gliptins and -to a lesser extent-glitazones is durability. No drug per se is able to maintain stable blood glucose control for years. Metformin, sulfonylureas and gliptins have demonstrated safety. Experience with the first two drug groups is more extensive. The main adverse effect of metformin is gastrointestinal discomfort. Major concerns related to the use of sulfonylureas are hypoglycemia and weight gain. The use of pioglitazone has been associated with an increased risk of bladder cancer, edema, heart failure, weight gain, and distal bone fractures in postmenopausal women. The most common adverse reactions associated with glucagon-like peptide-1 agonists are gastrointestinal discomfort that sometimes leads to treatment discontinuation.

    To evaluate the effect of short-term intensive insulin treatment on β-cell function in newly diagnosed type 2 diabetes patients with apparently hyperglycemia, twenty-four newly diagnosed type 2 diabetes patients with FPG more than 12.0 mmol/L were treated by short-term transient intensive insulin in average 9.04-4.8 days. Their β-cell function was assessed by oral glucose tolerance test. The FPG, HbAlc and HOMA IR of patients were significantly decreased (P<0.01), while the insulin, the Area Under Curve (AUC) of insulin and HOMA β were significantly increased (P<0.01) after the treatment with insulin. Improvement of β-cell function can be induced by short-term intensive insulin treatment for newly diagnosed type 2 diabetes patients with apparently hyperglycemia. (authors)

    Gonadotropin-releasing hormone agonist (GnRHa) is used as a therapeutic agent for central precocious puberty (CPP); however, increased obesity may subsequently occur. This study compared body mass index (BMI) and insulin resistance during the first year of GnRHa treatment for CPP. Patient group included 83 girls (aged 7.0-8.9 years) with developed breasts and a peak luteinizing hormone level of ≥5 IU/L after GnRH stimulation. Control group included 48 prepubertal girls. BMI and insulin resistance-related indices (homeostasis model assessment of insulin resistance [HOMA-IR] and quantitative insulin sensitivity check index [QUICKI]) were used to compare the groups before treatment, and among the patient group before and after GnRHa treatment. No statistical difference in BMI z -score was detected between the 2 groups before treatment. Fasting insulin and HOMA-IR were increased in the patient group; fasting glucose-to-insulin ratio and QUICKI were increased in the control group (all P resistance compared to the control group. During GnRHa treatment, normal-weight individuals showed increased BMI z -scores without increased insulin resistance; the overweight group demonstrated increased insulin resistance without significantly altered BMI z -scores. Long-term follow-up of BMI and insulin resistance changes in patients with CPP is required.

    The major malfunction in diabetes mellitus is severe perturbation of glucose homeostasis caused by deficiency of insulin.Insulin deficiency is either absolute due to destruction or failure of pancreaticβcells,or relative due to decreased sensitivity of peripheral tissues to insulin.The primary lesion being related to insulin,treatments for diabetes focus on insulin replacement and/or increasing sensitivity to insulin.These therapies have their own limitations and complications,some of which can be life-threatening.For example,exogenous insulin administration can lead to fatal hypoglycemic episodes;islet/pancreas transplantation requires life-long immunosuppressive therapy;and anti-diabetic drugs have dangerous side effects including edema,heart failure and lactic acidosis.Thus the need remains for better safer long term treatments for diabetes.The ultimate goal in treating diabetes is to re-establish glucose homeostasis,preferably through endogenously generated hormones.Recent studies increasingly show that extra-pancreatic hormones,particularly those arising from adipose tissue,can compensate for insulin,or entirely replace the function of insulin under appropriate circumstances.Adipose tissue is a versatile endocrine organ that secretes a variety of hormones with far-reaching effects on overall metabolism.While unhealthy adipose tissue can exacerbate diabetes through limiting circulation and secreting of pro-inflammatory cytokines,healthy uninflamed adipose tissue secretes beneficial adipokines with hypoglycemic and anti-inflammatory properties,which can complement and/or compensate for the function of insulin.Administration of specific adipokines is known to alleviate both type 1 and 2 diabetes,and leptin mono-therapy is reported to reverse type 1 diabetes independent of insulin.Although specific adipokines may correct diabetes,administration of individual adipokines still carries risks similar to those of insulin monotherapy.Thus a better approach is to

    Metformin-induced activation of the 5′-AMP-activated protein kinase (AMPK) has been associated with enhanced glucose uptake in skeletal muscle, but so far no direct causality has been examined. We hypothesized that an effect of in vivo metformin treatment on glucose uptake in mouse skeletal muscles is dependent on AMPK signaling. Oral doses of metformin or saline treatment were given to muscle-specific kinase dead (KD) AMPKα2 mice and wild-type (WT) littermates either once or chronically for 2 wk. Soleus and extensor digitorum longus muscles were used for measurements of glucose transport and Western blot analyses. Chronic treatment with metformin enhanced insulin-stimulated glucose uptake in soleus muscles of WT (∼45%, P metformin treatment. Insulin signaling at the level of Akt and TBC1D4 protein expression as well as Akt Thr308/Ser473 and TBC1D4 Thr642/Ser711 phosphorylation were not changed by metformin treatment. Also, protein expressions of Rab4, GLUT4, and hexokinase II were unaltered after treatment. The acute metformin treatment did not affect glucose uptake in muscle of either of the genotypes. In conclusion, we provide novel evidence for a role of AMPK in potentiating the effect of insulin on glucose uptake in soleus muscle in response to chronic metformin treatment. PMID:24644243

    The study aimed to explore the variability between the treatment decisions dentists make for MIH-affected teeth. In 2009, a pre-coded questionnaire was sent electronically to all dentists employed by the Public Dental Service (PDS) in Norway (n = 1061). The questions were related to treatment of MIH-affected teeth, including three patient cases illustrated by photographs and written case descriptions. Replies were obtained from 61.5 % of the respondents after two reminders. In the first case, showing a newly erupted first permanent molar with moderate hypomineralization and no disintegration of the surface enamel, the preferred treatment among the majority of the respondents (53.5 %) was application of fluoride varnish, while 19.6 % would seal the fissure with GIC material. In the second case, showing a severely damaged first permanent molar in a six year old child, more than half of the respondents (57.5 %) would place a conventional glass ionomer restoration and 10.5 % would use a stainless steel crown (SSC). In the third case, showing a severely damaged permanent first molar in a nine year old child, 43.8 % of the dentists would remove only the parts with soft, damaged enamel; while 35.2 % would remove more and 21.0 % would remove all affected enamel and leave the cavity margins in sound enamel. The survey shows that there is a wide disparity between clinicians' views on how MIH affected teeth should be treated. In a severely affected first permanent molar, only a minority of dentists would remove as much tooth substance as needed to get the full benefit of the acid etch pattern in sound enamel.

    There are no treatments for the core symptoms of autistic spectrum disorder (ASD), but there is now more knowledge on emerging mechanisms and on mechanism-based therapies. In autism there are altered synapses: genes affected are commonly related to synaptic and immune function. Dysregulation of activity-dependent signaling networks may have a key role the etiology of autism. There is an over-activation of IGF-AKT-mTor in autism spectrum disorders. Morphological and electro-physiological defects of the cerebellum are linked to system-wide ASD-like behavior defects. The molecular basis for a cerebellar contribution has been demonstrated in a mouse model. These have led to a potential mechanism-based use of drug targets and mouse models. Neurotrophic factors are potential candidates for the treatment. Insulin-like growth factor-1 (IGF-1) is altered in autism. It reduces neuro-inflammation: by causing changes of cytokines such as IL-6 and microglial function. IGF-1 reduces the defects in the synapse. It alleviates NMDA-induced neurotoxicity via the IGF-AKT-mTor pathway in microglia. IGF-1 may rescue function in Rett syndrome and ASD caused by changes of the SCHANK3 gene. There are recently pilot studies of the treatment of Rett syndrome and of SCHANK3 gene deficiency syndromes. The FDA has granted Orphan drug designations for Fragile X syndrome, SCHANK3 gene deficiency syndrome and Rett syndrome. Copyright © 2016 European Paediatric Neurology Society.

    Background: Endogenous or exogenous glucocorticoid (GC) excess (Cushing's syndrome) is characterized by increased adiposity and insulin resistance. Although GCs cause global insulin resistance in vivo, we have previously shown that GCs are able to augment insulin action in human adipose tissue, contrasting with their action in skeletal muscle. Cushing's syndrome develops following chronic GC exposure and, in addition, is a state of hyperinsulinemia. Objectives: We have therefore compared the ...

    Acute sore throat is commonly associated with viral infections. Consumers typically rely on over-the-counter treatments and other remedies to treat symptoms; however, limited information is available regarding consumer perceptions of sore throat or treatment needs. The aim of this study was to investigate perceptions of throat discomfort and how these influence attitudes and consumer behaviour with regard to treatment. Online consumer surveys were completed by participants invited by email between 2003 and 2004 in four markets: the UK, France, Poland, and Malaysia. The questionnaire consisted of 24 questions that covered key issues surrounding throat discomfort including incidence in the past 12 months, causes, severity, effects on functionality and quality of life, actions taken to relieve throat discomfort, the efficacy of these approaches and the reasons behind using specific products. In total, 6465 men and women aged ≥18 years were surveyed, identifying 3514 participants who had suffered throat discomfort/irritation in the past 12 months (response rate of 54%). These participants completed the full survey. The breakdown of throat discomfort sufferers was: UK, 912; France, 899; Poland, 871; Malaysia, 832. A high proportion of respondents experienced one or more instances of throat discomfort in the previous 12 months, with an overall incidence of 54%. Infections including the common cold/influenza and other bacteria/viruses were commonly perceived causes of throat discomfort (72% and 46%, respectively). Physical and environmental factors were also perceived to be causative, including airborne pollution (28%), smoking (23%), and air conditioning (31%). Symptoms perceived to be caused by an infection were associated with a higher degree of suffering (mean degree of suffering for bacteria/virus and common cold/influenza; 3.4 and 3.0, respectively). Medicinal products were used for all perceived causes, but more commonly for sore throats thought to be caused by

    Lixisenatide is a potent, selective and short-acting once daily prandial glucagon-like peptide-1 receptor agonist which lowers glycohemoglobin and body weight by clinically significant amounts in patients with type 2 diabetes treated with basal insulin, with limited risk of hypoglycemia. To assess the cost-effectiveness of lixisenatide versus bolus insulin, both in combination with basal insulin, in patients with type 2 diabetes in Norway. The IMS CORE Diabetes Model, a non-product-specific and validated simulation model, was used to make clinical and cost projections. Transition probabilities, risk adjustments and the progression of complication risk factors were derived from the UK Prospective Diabetes Study, supplemented with Norwegian data. Patients were assumed to receive combination treatment with basal insulin, lixisenatide or bolus insulin therapy for 3 years, followed by intensification of a basal-bolus insulin regimen for their remaining lifetime. Simulated healthcare costs, taken from the public payer perspective, were derived from microcosting and diagnosis related groups, discounted at 4% per annum and reported in Norwegian krone (NOK). Productivity costs were also captured based on extractions from the Norwegian Labor and Welfare Administration. Health state utilities were derived from a systematic literature review. Sensitivity and scenario analyses were performed. Lixisenatide in combination with basal insulin was associated with increased quality-adjusted life years (QALYs) and reduced lifetime healthcare costs compared to bolus insulin in combination with basal insulin in patients with Type 2 diabetes, and can be considered dominant. The net monetary benefit of lixisenatide versus bolus insulin was NOK 39,369 per patient. Results were sensitive to discounting, the application of excess body weight associated disutility and uncertainty surrounding the changes in HbA1c. Lixisenatide may be considered an economically efficient therapy in combination

    Full Text Available Elizabeth M Lamos,1 Lisa M Younk,2 Stephen N Davis3 1Division of Endocrinology, Diabetes and Nutrition, 2Department of Medicine, University of Maryland School of Medicine, 3Department of Medicine, University of Maryland Medical Center, Baltimore, MD, USA Introduction: Insulin therapy plays a critical role in the treatment of type 1 and type 2 diabetes mellitus. However, there is still a need to find basal insulins with 24-hour coverage and reduced risk of hypoglycemia. Additionally, with increasing obesity and insulin resistance, the ability to provide clinically necessary high doses of insulin at low volume is also needed. Areas covered: This review highlights the published reports of the pharmacokinetic (PK and glucodynamic properties of concentrated insulins: Humulin-R U500, insulin degludec U200, and insulin glargine U300, describes the clinical efficacy, risk of hypoglycemic, and metabolic changes observed, and finally, discusses observations about the complexity of introducing a new generation of concentrated insulins to the therapeutic market. Conclusion: Humulin-R U500 has a similar onset but longer duration of action compared with U100 regular insulin. Insulin glargine U300 has differential PK/pharmacodynamic effects when compared with insulin glargine U100. In noninferiority studies, glycemic control with degludec U200 and glargine U300 is similar to insulin glargine U100 and nocturnal hypoglycemia is reduced. Concentrated formulations appear to behave as separate molecular entities when compared with earlier U100 insulin analog compounds. In the review of available published data, newer concentrated basal insulins may offer an advantage in terms of reduced intraindividual variability as well as reducing the injection burden in individuals requiring high-dose and large volume insulin therapy. Understanding the PK and pharmacodynamic properties of this new generation of insulins is critical to safe dosing, dispensing, and administration

    There is increasing evidence that the pathophysiology of type 2 diabetes mellitus (T2DM) in Asian patients differs from that in Western patients, with early phase insulin deficiencies, increased postprandial glucose excursions, and increased sensitivity to insulin. Asian patients may also experience higher rates of gastrointestinal adverse events associated with glucagon-like peptide-1 receptor agonists (GLP-1RAs), such as nausea and vomiting, compared with their Western counterparts. These factors should be taken into consideration when selecting therapy for basal insulin treatment intensification in Asian patients. However, the majority of studies to establish various agents for treatment intensification in T2DM have been conducted in predominantly Western populations, and the levels of evidence available in Chinese or Asian patients are limited. This review discusses the different mechanisms of action of short-acting, prandial, and long-acting GLP-1RAs in addressing hyperglycemia, and describes the rationale and available clinical data for basal insulin in combination with the short-acting prandial GLP-1RA lixisenatide, with a focus on treatment of Asian patients with T2DM. © 2016 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    This study examined the reliability and validity of the Brazilian Portuguese version of the Treatment Satisfaction Questionnaire for Medication (version 1.4) among patients with hypertension. Understanding the patient experience with treatment satisfaction will contribute to improved medication adherence and control of hypertension. Hypertension is a serious problem in Brazil that is associated with chronic illness controlled, in part, by consistent adherence to medications. Patient satisfaction with medication treatment is associated with adherence to medication. The Treatment Satisfaction Questionnaire for Medication (version 1.4) is a promising instrument for measuring medication; however, to date there has been no report of the reliability and validity of the instrument with Portuguese-speaking adults with hypertension in Brazil. Cross-sectional descriptive exploratory study. A convenience sample of 300 patients with hypertension in an outpatient setting in the southeast region of São Paulo state in Brazil completed the Treatment Satisfaction Questionnaire for Medication (version 1.4). The instrument, comprised of four subscales, was evaluated for reliability using correlation analyses and internal consistency. Confirmatory factor analysis was used to determine factorial validity. Correlational analyses, internal consistency (Cronbach's alpha) and hierarchical confirmatory factor analysis demonstrate adequate support for the four-factor dimensionality, reliability and factorial validity of the Treatment Satisfaction Questionnaire for Medication (version 1.4). This study provides modest evidence for internal consistency and factorial validity of the Treatment Satisfaction Questionnaire for Medication (version 1.4) in Portuguese-speaking adult Brazilians with hypertension. Future testing should focus on extending reliability testing, discriminant validity and potential translation and literacy issues in this population. Within known limitations, clinicians will

    Gestational diabetes mellitus (GDM) has a higher incidence of neonatal respiratory distress syndrome, and lipogenesis is required for the synthesis of pulmonary surfactants. The aim of this study was to determine the effect of insulin treatment in GDM on the production of lipids in the lungs of fetal rats. GDM was induced by streptozotocin, and insulin was used to manage diabetes. Type II alveolar epithelial cells (AEC II), bronchoalveolar lavage fluid (BALF), and lung tissues of the neonatal rats were sampled for analyses. Insulin treatment could not decrease plasma glucose to normal level at a later gestational stage. Lipids/phospholipids in AEC II, BALF, and lung tissues decreased in GDM, and insulin treatment could not increase the levels; quantitative PCR and western blotting demonstrated a lower level of sterol regulator element-binding protein 1 (SREBP-1), SREBP cleavage-activating protein (SCAP), and insulin-induced gene 1 (INSIG-1) in GDM, but insulin treatment upregulated only SREBP-1. Nuclear translocation of the SREBP-1 protein in AEC II was impaired in GDM, which could not be ameliorated by insulin treatment. These findings indicated that insulin treatment in GDM cannot promote lipogenesis in the fetal lung because of failure to redress the imbalance among SREBP-1, SCAP, and INSIG-1.

    Purpose: The goal of this prospective, randomized study was to assess and compare compliance of patients diagnosed with prostate cancer to completing three different validated QOL instruments pre-treatment and six months later. Materials and Methods: Between April 2000 and April 2001, 124 patients were asked to fill out only one of three randomly selected QOL questionnaires (version A, B, C). Each addressed urinary and sexual function. One also addressed patients' physical, social, family, emotional, and functional well being. Study patients received External Beam Radiation Therapy (EBRT) or Brachytherapy (BRACHY), according to departmental policy. Exclusion criteria included current/previous hormone therapy and prostatectomy. Patients were asked to return the questionnaire at their first treatment visit. The three tools were: A The Functional Assessment of Cancer Therapy for Prostate Patients (FACT-P), The Sexual Adjustments Questionnaire (SAQ), and The American Urological Association (AUA) Questionnaire. The Fact-P questionnaire elicits information about physical, social, family, emotional, and functional well being as they relate to prostate cancer. SAQ focuses on sexual function; the AUA on urinary symptoms. B SAQ and AUA only; identical to Version A, but does not address physical, social, family, emotional, and functional well-being. C The International Prostate Symptom Score (I-PSS) Questionnaire, which addresses urinary symptoms and Patient Sexual Function Questionnaire, which focuses on erectile function. Additionally, patients were asked to respond yes/no to four variables designed to evaluate these questionnaires: 1) ease of understanding, 2) too personal, 3)addresses concerns regarding urinary function and sexual potency and 4) willingness to complete questionnaire in six months. These variables were examined for any trends that may exist between the different questionnaires. Results: Fifteen (12%) of the 124 patients returned incomplete questionnaires

    Recent studies indicated that insulin resistance may contribute to the pathogenesis of polycystic ovary syndrome (PCOS); however, the specific mechanism is still unclear. To investigate the effect of sodium aescinate (SA) on PCOS-IR rat models. Sixty rats were randomly divided into the five groups: un-treated rats (n = 12), PCOS-IR group (n = 12), PCOS-IR group plus 50 mg/kg SA (n = 12), PCOS-IR group plus 10 mg/kg SA (n = 12), PCOS-IR group plus 150 mg/kg metformin (n = 12). On day 21, rats were sacrificed, and H(and)E staining was performed for histopathologic examination of the ovaries; moreover, the serum level of follicle-stimulating hormone (FSH), testosterone, and luteotropic hormone (LH) were measured, and the expression as well as phosphorylation of PI3K, Akt and Gsk-3β were examined using western blot assay. High dosage of SA treatment improved the morphological features of the ovaries in PCOS rats, and also induced significant decrease in serum expression of testosterone and LH/FSH ratio and significant decrease in the expression of p-PI3K, p-Akt and p-Gsk-3β. Our results demonstrated that SA treatment could alleviate the symptom of PCOS in rat model through regulating the PI3K/Akt/GSK3-β pathway (Fig. 4, Ref. 22).

    Hyperthyroidism is associated with altered growth hormone (GH) secretion. Many patients with thyroid dysfunction experience several poorly described complications such as symptoms and signs also seen in patients with growth hormone deficiency (GHD). We have therefore prospectively evaluated a possible relationship between the thyroid function, body composition, leptin levels and insulin-like growth factor (IGF) related peptides in patients with Graves' disease. DESIGN, PATIENTS, AND MEASUREMENTS: In a prospective group of 24 fasting female patients with Graves' disease (mean age (CI 95%): 40 years (33-47)), we measured serum thyroxine, triiodothyronine, thyrotropine (TSH), TSH receptor antibodies, anti-thyroid peroxidase, leptin, body composition, body mass index (BMI) and IGF-related peptides at diagnosis and after 12 months of treatment with thiamazol (ATD). In thyrotoxic patients IGF-I plus IGF-II correlated positively with IGFBP-3 at baseline (r = 0.90, p secretion during treatment of autoimmune thyroid disease influence IGF-related peptides leaving the patient in a state somewhat similar to partial GHD, but the mechanism behind these alterations remains unclear.

    The handling of advance directives (AD) in prehospital emergency treatment in Germany is characterized by instability. In the project "Advance directives in preclinical emergency medical aid" ("Patientenverfügungen in der präklinischen Notfallmedizin") the frequency and quality of ADs in emergency situations was investigated. The aim of this study was to fill the gaps in research and to collate data on how consideration of the self-determination of patients in emergency situations can be optimized. Over a period of 12 months from December 2007 to December 2008 a questionnaire was included in the emergency documentation of the medical emergency service in Aachen. Emergency patients were asked by emergency physicians to provide an AD and the quantitative as well as qualitative features of these ADs were examined. Furthermore, the study recorded what kinds of problems occurred with ADs in emergency situations and what measures were needed to correct this deficiency. The reactions of patients were documented on a numeral rating scale with a score of 1 reflecting a negative and 10 reflecting a positive reaction. In the 12-month period emergency doctors recorded 1,321 missions and after application of the exclusion criteria (e.g. missing signature, incomplete documentation and late delivery) 1,047 documented questionnaires were available for the analysis. A total of 127 out of 1,047 emergency patients provided an AD, 44 had a durable power of attorney and 27 had appointed a legal representative for healthcare. Of the emergency patients 20 had a legal attendant and 43 out of the 127 ADs could be presented to the emergency team during the emergency mission. The emergency team often encountered difficulties regarding the handling of the ADs due to the time factor and unclear wording. The latter included the following problems: misleading formulation (19.1 %), difficulty with the complexity (14.9 %) and contradicting information (4 %). Only 29 (61.7 %) of the

    Full Text Available Abstract Background The 14-item Treatment Satisfaction Questionnaire for Medication (TSQM Version 1.4 is a reliable and valid instrument to assess patients' satisfaction with medication, providing scores on four scales – side effects, effectiveness, convenience and global satisfaction. In naturalistic studies, administering the TSQM with the side effects domain could provoke the physician to assess the presence or absence of adverse events in a way that is clinically atypical, carrying the potential to interfere with routine medical care. As a result, an abbreviated 9-item TSQM (TSQM-9, derived from the TSQM Version 1.4 but without the five items of the side effects domain was created. In this study, an interactive voice response system (IVRS-administered TSQM-9 was psychometrically evaluated among patients taking antihypertensive medication. Methods A total of 3,387 subjects were invited to participate in the study from an online panel who self-reported taking a prescribed antihypertensive medication. The subjects were asked to complete the IVRS-administered TSQM-9 at the start of the study, along with the modified Morisky scale, and again within 7 to 14 days. Standard psychometric analyses were conducted; including Cronbach's alpha, intraclass correlation coefficients, structural equation modeling, Spearman correlation coefficients and analysis of covariance (ANCOVA. Results A total of 396 subjects completed all the study procedures. Approximately 50% subjects were male with a good racial/ethnic mix: 58.3% white, 18.9% black, 17.7% Hispanic and 5.1% either Asian or other. There was evidence of construct validity of the TSQM-9 based on the structural equation modeling findings of the observed data fitting the Decisional Balance Model of Treatment Satisfaction even without the side effects domain. TSQM-9 domains had high internal consistency as evident from Cronbach's alpha values of 0.84 and greater. TSQM-9 domains also demonstrated good test

    This work reports the experience with use of continuous subcutaneous insulin infusion (CSII) in 112 type 1 diabetic patients followed up for 7 years and previously treated with multiple daily insulin injections (MDII). A retrospective, observational study in 112 patients with diabetes mellitus treated with CSII from 2005 to 2012, previously treated with MDII and receiving individualized diabetic education with a specific protocol. Variables analyzed included: prevalence of the different indications of pump treatment; mean annual HbA1c and fructosamine values before and after CSII treatment; and hypoglycemia frequency and symptoms. The most common reason for pump treatment was brittle diabetes (74.1%), followed by frequent or severe hypoglycemia or hypoglycemia unawareness (44.6%). Other indications were irregular food intake times for professional reasons (20.2%), dawn phenomenon (15.7%), pregnancy (12.3%), requirement of very low insulin doses (8.9%), and gestational diabetes (0.9%). HbA1c decreased by between 0.6% and 0.9%, and fructosamine by between 5.1% and 12.26%. Nine percent of patients experienced hypoglycemia weekly, 24% every two weeks, and 48% monthly. No hypoglycemia occurred in 19% of patients. Only 10% had neuroglycopenic symptoms. Hypoglycemia unawareness was found in 21%. Hypoglycemia was more common at treatment start, and its frequency rapidly decreased thereafter. CSII therapy provides a better glycemic control than MDII treatment. Specific patient training and fine adjustment of insulin infusion doses are required to prevent hypoglycemic episodes, which are the most common complications, mainly at the start of treatment.

    Lipid profile and insulin resistance (IR) are associated with hepatitis C virus (HCV) and may predict the chronic hepatitis C (CHC) treatment response. The aim of this study was to determine the association between CHC treatment response and lipid profile and IR change during treatment. In total, 203 CHC patients were reviewed retrospectively between January 2005 and December 2011 at Soon Chun Hyang University Hospital. The lipid profile, homeostasis model for assessment (HOMA) of IR (HOMA-IR), and HOMA of β cells (HOMA-β) were evaluated before interferon plus ribavirin therapy (BTx), at the end of treatment (DTx), and 24 weeks after the end of treatment (ATx). A sustained virologic response (SVR) was achieved by 81% of all patients (49/60), 60% (n=36) of whom possessed genotype 1, with the remainder being non-genotype-1 (40%, n=24). Apart from age, which was significantly higher in the non-SVR group (SVR, 48.0 ± 11.2 years, mean ± SD; non-SVR, 56.6 ± 9.9 years; PC) had significantly changed at DTx and ATx compared to BTx. In addition, HOMA-IR and HOMA-β were significantly changed at DTx in the SVR group. Among those with a high baseline insulin resistance (HOMA-IR >2.5), HOMA-IR was significantly changed at DTx in the SVR group. LDL-C appears to be associated with HCV treatment in SVR patients. Furthermore, eradication of HCV may improve whole-body IR and insulin hypersecretion, as well as high baseline insulin resistance (HOMA-IR >2.5).

    Although metformin is widely used to improve insulin resistance in women with polycystic ovary syndrome (PCOS), its mechanism of action is complex, with inconsistent effects on insulin sensitivity and variability in treatment response. The aim of the study was to delineate the effect of metformin on glucose and insulin parameters, determine additional treatment outcomes, and predict patients with PCOS who will respond to treatment. We conducted an open-label, interventional study at an academic medical center. Women with PCOS (n = 36) diagnosed by the National Institutes of Health criteria participated in the study. Subjects underwent fasting blood sampling, an IV glucose tolerance test, dual-energy x-ray absorptiometry scan, transvaginal ultrasound, and measurement of human chorionic gonadotropin-stimulated androgen levels before and after 12 weeks of treatment with metformin extended release 1500 mg/d. Interval visits were performed to monitor anthropometric measurements and menstrual cycle parameters. Changes in glucose and insulin parameters, androgen levels, anthropometric measurements, and ovulatory menstrual cycles were evaluated. Insulin sensitivity did not change despite weight loss. Glucose effectiveness (P = .002) and the acute insulin response to glucose (P = .002) increased, and basal glucose levels (P = .001) decreased after metformin treatment. T levels also decreased. Women with improved ovulatory function (61%) had lower baseline T levels and lower baseline and stimulated T and androstenedione levels after metformin treatment (all P effectiveness and insulin sensitivity, metformin does not improve insulin sensitivity in women with PCOS but does improve glucose effectiveness. The improvement in glucose effectiveness may be partially mediated by decreased glucose levels. T levels also decreased with metformin treatment.

    The treatment of type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) using insulin is not ideal at this time. Despite advances made with basal insulin analogues, many individuals achieve less than optimal glycemic control or are at risk for hypoglycemia. Currently available basal insulin analogues do not deliver steady, peakless, continuous insulin for >24 hours and are associated with adverse events, including hypoglycemia. The objective of this paper was to review the clinical efficacy and safety of upcoming long-acting insulin analogues such as insulin degludec and insulin glargine 300 U/mL (Gla-300). A comprehensive literature search of PubMed and Google Scholar was conducted from 1966 to 2015. The search included randomized controlled trials that specifically assessed the efficacy and safety of insulin degludec and Gla-300 in patients with T1DM and T2DM. The efficacy of insulin degludec and Gla-300 in achieving glycemic control has been reported in clinical trials in adults with T1DM and T2DM. Not only did a large number of patients succeed in meeting glycosylated hemoglobin targets, but they also experienced reductions in hypoglycemic events. These 2 therapies are associated with a reduced risk of nocturnal hypoglycemia and are generally well tolerated. The long-acting insulin analogues insulin degludec and Gla-300 are promising therapies in the treatment of T1DM and T2DM. Their improved insulin delivery for >24 hours offers glycemic control with a good safety profile. Copyright © 2017 Elsevier HS Journals, Inc. All rights reserved.

    Based on the known effect of metformin (MET) in improving insulin sensitivity in type 2 diabetes, with the scope to focus the effects on glycaemic and free fatty acids (FFA) levels, we studied the effects of a short-term treatment with this drug in obese subjects and obese patients with diabetes or family history of diabetes (FHD). We used a method to allow us to evaluate the possible difference of insulin sensibility with regard to the insulin action on glycaemia and blood FFA, both in the basal state and during oral glucose tolerance test (OGTT). Insulin sensitivity was investigated before and after MET treatment (850 mg bid for 10 days) in seven obese subjects with normal glucose tolerance and without FHD and 13 obese patients with diabetes (n=7) or FHD (n=6). By using specifically designed formulae, we calculated four insulin-sensitivity indices (ISI) from basal level (b) and area values (a) (during OGTT) of insulinaemia, glycaemia (gly) or FFA (ffa), namely: ISI (gly)-b, ISI (gly)-a, ISI (ffa)-b and ISI (ffa)-a. In patients with diabetes or FHD, MET improved ISI (gly)-b (0.79 +/- 0.06 vs. 0.59 +/- 0.07, p<0.001) and ISI (gly)-a (0.69 +/- 0.09 vs. 0.51 +/- 0.07, p<0.05), whereas only minor changes occurred for ISI (ffa)-b and ISI (ffa)-a. In contrast, in simple obese subjects, MET induced further deterioration of both ISI (gly)-a (0.47 +/- 0.07 vs. 0.64 +/- 0.10, p<0.01) and ISI (ffa)-a (0.43 +/- 0.07 vs. 0.55 +/- 0.08, p<0.05). Fasting level and total area of lactate were high in the obese patients and were not affected by MET. A statistically significant increase (p<0.01), however, was observed for the 'decremental' area of lactate in obese subjects with diabetes or FHD, which might probably contribute to the reduction of insulin resistance induced by the drug in these patients. Although the low number of subjects studied precludes absolute conclusions, data would suggest that MET improved ISI towards glucose but not towards FFA, in the diabetic and

Control of diabetes is often unsatisfactory because the patient does not know about the principles of successful insulin therapy (ie, blood glucose self-monitoring, the principles of insulin administration, titration, current dose adjustments, dietary recommendations, and physical activity preventive measures or because these principles are applied incorrectly or insufficiently. Furthermore, the fear of hypoglycemia may lead to maintaining higher than recommended blood glucose levels. Methods/design: This is a noninterventional, international study focusing on a questionnaire survey of diabetes patients (patient-reported outcome treated with insulin for at least 1 year. It is designed so that the data obtained reflect real access of patients to insulin treatment. The primary objective is to show the results of glycemic control of diabetes (HbA1c achieved in diabetes patients treated with at least one dose of insulin. The secondary objective is to monitor the factors potentially affecting these results, which include the frequency and other characteristics of hypoglycemia, the frequency of blood glucose self-monitoring, and the effects produced when the results

    Beta-cell proliferation is regulated by various metabolic demands including peripheral insulin resistance, obesity, and hyperglycemia. In addition to enhancement of glucose-induced insulin secretion, agonists for glucagon-like peptide-1 receptor (GLP-1R) stimulate proliferation and inhibit apoptosis of beta-cells, thereby probably preserve beta-cell mass. To evaluate the beta-cell preserving actions of GLP-1R agonists, we assessed the acute and chronic effects of exendin-4 on beta-cell proliferation, mass and glucose tolerance in C57BL/6J mice under various conditions. Short-term administration of high-dose exendin-4 transiently stimulated beta-cell proliferation. Comparative transcriptomic analysis showed upregulation of IGF-1 receptor and its downstream effectors in islets. Treatment of mice with exendin-4 daily for 4 weeks (long-term administration) and feeding high-fat diet resulted in significant inhibition of weight gain and improvement of glucose tolerance with reduced insulin secretion and beta-cell mass. These findings suggest that long-term GLP-1 treatment results in insulin sensitization of peripheral organs, rather than enhancement of beta-cell proliferation and function, particularly when animals are fed high-fat diet. Thus, the effects of exendin-4 on glucose tolerance, insulin secretion, and beta-cell proliferation largely depend on treatment dose, duration of treatment and meal contents. While GLP-1 enhances proliferation of beta-cells in some diabetic mice models, our results suggest that GLP-1 stimulates beta-cell growth only when expansion of beta-cell mass is required to meet metabolic demands.

    Generation of new β cells is an important approach in the treatment of type 1 diabetes mellitus (type 1 DM). Adipose tissue-derived stem cells (ADSCs) might be one of the best sources for cell replacement therapy for diabetes. Therefore, this work aimed to test the possible role of transplanted insulin-producing cells (IPCs) differentiated from ADSCs in treatment of streptozotocin (STZ) induced type I DM in rats. Type 1 DM was induced by single intra peritoneal injection with STZ (50 mg/kg BW). Half of the diabetic rats were left without treatment and the other half were injected with differentiated IPCs directly into the pancreas. ADSCs were harvested, cultured and identified by testing their phenotypes through flow cytometry. They were further subjected to differentiation into IPCs using differentiation medium. mRNA expression of pancreatic transcription factors (pdx1), insulin and glucose transporter-2 genes by real time PCR was done to detect the cellular differentiation and confirmed by stimulated insulin secretion. The pancreatic tissues from all groups were examined 2 months after IPC transplantation and were subjected to histological, Immunohistochemical and morphometric study. The differentiated IPCs showed significant expression of pancreatic β cell markers and insulin secretion in glucose dependent manner. Treatment with IPCs induced apparent regeneration, diffused proliferated islet cells and significant increase in C-peptide immune reaction. We concluded that transplantation of differentiated IPCs improved function and morphology of Islet cells in diabetic rats. Consequently, this therapy option may be a promising therapeutic approach to patient with type 1 DM if proven to be effective and safe. Copyright © 2018 Elsevier B.V. All rights reserved.

    The use of dipeptidyl peptidase (DPP)-4 inhibitors in patients with type 2 diabetes treated with insulin may be beneficial. However, the long-term efficacy and safety of vildagliptin add-on therapy in these patients remains unclear. A total of 73 patients with type 2 diabetes treated with insulin were randomly assigned to receive either add-on therapy of vildagliptin (n=37) or conventional therapy without DPP-4 inhibitors (n=36) for glucose control. Hemoglobin A1c (HbA1c) levels, dose and number of insulin injections, number of hypoglycemia episodes, and liver and renal function were monitored for 2years. The baseline characteristics of subjects, including age, dose of insulin injections, or HbA1c levels, did not differ between the two groups. In the vildagliptin group, HbA1c levels significantly decreased and the significance of HbA1c reduction was maintained for 24months (from 8.0±1.2% to 7.4±1.0%, pinsulin injections significantly reduced (-5.6units, p1, and -0.9 times, p1). However, these parameters were unchanged in the control group. The number of patients who experienced three or more episodes of hypoglycemia per year was significantly lower in the vildagliptin group (n=4) than in the control group (n=11) (odds ratio, 0.28; 95% confidence interval, 0.08-0.97; pinsulin treatment for 24months was well tolerated and led to sustained reductions in HbA1c, the dose and number of insulin injections, and the risk of hypoglycemia.

    This paper sums up recently published researches on the continuous subcutaneous insulin infusion (CSII) with the use of insulin pump in children and adolescents with diabetes type 1. Obtaining a balance in the organism metabolism in childhood and adolescence diabetology is nowadays one of the most important rules of the diabetes management in children. One of the modern ways to achieve that goal is the intensive insulin therapy model with use of the insulin pump. In this paper the advantages and disadvantages as well as the indications and contraindications for the CSII in children and adolescents with diabetes are widely discussed.

    Nanoparticles have demonstrated significant advancements in potential oral delivery of insulin. In this publication, we review the current status of polymeric, inorganic and solid-lipid nanoparticles designed for oral administration of insulin. Firstly, the structure and physiological function of insulin are examined. Then, the efficiency and shortcomings of insulin nanoparticle are discussed. These include the susceptibility to digestive enzyme degradation, instability in the acidic pH environment, poor mucus diffusion and inadequate permeation through the gastrointestinal epithelium. In order to optimise the nanocarriers, the following considerations, including polymer nature, surface charge, size, polydispersity index and morphology of nanoparticles, have to be taken into account. Some novel designs such as chitosan-based glucose-responsive nanoparticles, layer by layer technique-based nanoparticles and zwitterion nanoparticles are being adopted to overcome the physiological challenges. The review ends with some future directions and challenges to be addressed for the success of oral delivery of insulin-loaded nanoparticle formulation. Copyright © 2017 Elsevier B.V.

    To evaluate effects of intensive insulin treatment modalities on cardiovascular biomarkers in patients with type 1 diabetes mellitus (T1DM). A total of 25 patients with T1DM receiving intensive insulin therapy either in the form of continuous insulin pump (IP group; n=13) or as multiple daily injections (MDI group; n=12) and 13 controls (control group, n=13) were included. Data on demographics, anthropometrics, diabetes history, and laboratory findings including glycemic and lipid parameters, and cardiovascular biomarkers [C-reactive protein (mg/dL), homocysteine (μmol/L), fibrinogen (mg/dL), oxidized LDL (ng/dL), PAI-1 (ng/mL), MCP-1 (pg/mL) and VEGF (pg/mL)] were recorded in each group. Correlation of cardiovascular biomarkers to other parameters was also evaluated in T1DM patients. Apart from significantly higher mean (SD) values for HbA1c [6.1 (0.3) vs. 5.6 (0.5)% (43 (3) vs. 38 (5) mmol/mol), p1.5 (13.6) vs. 58.2 (10.8), p1) in the IP than in the MDI group, no significance difference was noted between insulin treatment modalities as well as between patient and control groups in terms of demographic, anthropometric and laboratory parameters. Negative correlation of MCP-1 to treatment duration (r=-0.615, p=0.025), and HDL-c to CRP (r=-0.685, p=0.010) and VEGF (r=-0.678, p=0.011) was noted in IP group, whereas positive correlation of PAI-1 to diabetes age (r=0.805, p=0.002) and treatment duration was noted in MDI group. Our findings in a cohort of T1DM patients with optimal glycemic control revealed that intensive insulin therapy was not associated with an increase in atherosclerotic markers in T1DM, regardless of whether continuous IP infusion or MDIs was administered.

    The authors evaluated the effect of metformin (N,N-dimethylbiguanide), a biguanide known to be less toxic than phenformin, on insulin binding to its receptors, both in vitro and in vivo. Specific 125 I-insulin binding to cultured IM-9 human lymphocytes and MCF-7 human breast cancer cells was determined after preincubation with metformin. Specific 125 I-insulin binding to circulating monocytes was also evaluated in six controls, eight obese subjects, and six obese type II diabetic patients before and after a short-term treatment with metformin. Plasma insulin levels and blood glucose were also measured on both occasions. Metformin significantly increased insulin binding in vitro to both IM-9 lymphocytes and MCF-7 cells; the maximum increment was 47.1% and 38.0%, respectively. Metformin treatment significantly increased insulin binding in vivo to monocytes of obese subjects and diabetic patients. Scatchard analysis indicated that the increased binding was mainly due to an increase in receptor capacity. Insulin binding to monocytes of normal controls was unchanged after metformin as were insulin levels in all groups; blood glucose was significantly reduced after metformin only in diabetic patients. These data indicate that metformin increases insulin binding to its receptors in vitro and in vivo. The effect in vivo is observed in obese subjects and in obese type II diabetic patients, paralleling the clinical effectiveness of this antidiabetic agent, and is not due to receptor regulation by circulating insulin, since no variation in insulin levels was recorded

    Patient well-being is always the goal of rehabilitation of edentulism; however, evaluations of treatment success often overlook the patient's subjective feelings about comfort, function, speech, social image, social inhibitions, psychological discomfort, and/or disabilities. The purpose of this study was to assess these patient responses using an oral health questionnaire. To assess such feelings, a self-administered 20-question multiple-choice patient-reported Edentulous Patient Impact Questionnaire was developed, based upon the previously validated Oral Health Impact Profile patient-assessment tool. Responses were solicited from randomly selected patients treated with an implant-supported, fixed, immediately loaded full arch prosthesis. The questionnaires were completed by 250 patients. Of the respondents, 95% described themselves as being either extremely satisfied (74%) or satisfied (21%) with their new teeth, and 98% said they would definitely recommend similar treatment (88%) or consider recommending it (10%) to a friend or colleague. Based upon an oral health impact survey completed by 250 patients treated with full-arch implant-supported, immediately loaded fixed dental prostheses, it appears that patient satisfaction is high and that treated patients would generally be willing to recommend this treatment to others.

    Clinicians are incorporating patient-reported outcomes in the management of HIV-infected persons co-infected with hepatitis C virus (HCV), but there are no validated inventories to monitor symptoms of patients during HCV therapy. Five-year retrospective cohort analysis of persons living with HIV (PLWH) treated for HCV. The HCV symptom-inventory (HCV-SI) was administered before, during, and after HCV treatment. Discriminant validity was assessed, separately, in mixed model linear regression of HCV-SI T-scores on treatment regimens (pegylated-interferon and ribavirin; pegylated-interferon, ribavirin, and telaprevir; and interferon-free antivirals); and side effect-related premature treatment discontinuation (SE-DC). From the 103 patients who completed the HCV-SI, 7% were female, 26% non-white, 32% cirrhotics and 91% had undetectable HIV viral loads. Most had genotype 1 (83%) and were HCV treatment-naïve (78%). We treated 19% of patients with pegylated-interferon and ribavirin, 22% with pegylated-interferon, ribavirin, and telaprevir and 59% received interferon-free antivirals. Overall, 77% achieved a sustained virologic response, and 6% discontinued HCV treatment due to side effects. In the treatment discrimination model, compared to the no treatment period, HCV-SI scores were significantly (p < 0.01) lower for interferon-free antivirals and higher for interferon-containing regimens. In the SE-DC model, the total HCV-SI, somatic and neuropsychiatric scores significantly predicted those patients who prematurely discontinued HCV treatment (P < 0.05). The HCV-SI effectively differentiated among treatment regimens known to vary by side effect profiles and between patients with and without treatment discontinuation due to side effects. The HCV-SI may have value as a patient-reported outcome instrument predicting the risk of HCV treatment discontinuation.

    Polycystic ovary syndrome (PCOS) is associated with insulin resistance and increased risk of type 2 diabetes. Skeletal muscle is the major site of insulin mediated glucose disposal and the skeletal muscle tissue is capable to synthesize, convert and degrade androgens. Insulin sensitivity is conserved in cultured myotubes (in vitro) from patients with PCOS, but the effect of testosterone on this insulin sensitivity is unknown. We investigated the effect of 7days testosterone treatment (100nmol/l) on glucose transport and gene expression levels of hormone receptors and enzymes involved in the synthesis and conversion of testosterone (HSD17B1, HSD17B2, CYP19A1, SRD5A1-2, AR, ER-α, HSD17B6 and AKR1-3) in myotubes from ten patients with PCOS and ten matched controls. Testosterone treatment significantly increased aromatase and androgen receptor gene expression levels in patients and controls. Glucose transport in myotubes was comparable in patients with PCOS vs. controls and was unchanged by testosterone treatment (p=0.21 PCOS vs. controls). These results suggest that testosterone treatment of myotubes increases the aromatase and androgen receptor gene expression without affecting insulin sensitivity and if testosterone is implicated in muscular insulin resistance in PCOS, this is by and indirect mechanism.

    Adherence to preventive drug treatment is a clinical problem and we hypothesised that patients' beliefs about medicines and stroke are associated with adherence. The objective was to examine associations between beliefs of patients with stroke about stroke and drug treatment and their adherence to drug treatment. Cross-sectional questionnaire survey. Patients with stroke from 25 Swedish hospitals were included. Questionnaires were sent to 989 patients to assess their perceptions about stroke (Brief Illness Perception Questionnaire, Brief IPQ), beliefs about medicines (Beliefs about Medicines Questionnaires, BMQ) and adherence to treatment (Medication Adherence Report Scale, MARS) 3 months after stroke onset. Only patients living at home were included in the analysis. The primary outcome was self-reported adherence as measured on MARS. MARS scores were dichotomised into adherent/non-adherent. Background and clinical data from the Swedish Stroke register were included. 811 patients were still living at home and 595 answered the questionnaire. Complete MARS data were available for 578 patients and 72 (12.5%) of these were classified as non-adherent. Non-adherent patients scored lower on positive beliefs as measured on BMQ-necessity (OR = 0.90, 95% CI 0.83 to 0.98) and BMQ-benefit (OR=0.77, 95% CI 0.68 to 0.87), and higher on negative beliefs as measured on BMQ-concern (OR=1.12, 95% CI 1.05 to 1.21), BMQ-overuse (OR=1.29, 95% CI 1.14 to 1.45), and BMQ-harm (OR=1.12, 95% CI 1.01 to 1.24). The Brief IPQ showed that non-adherent patients believed their current treatment to be less useful (p=0.001). This study showed associations between beliefs of Swedish patients with stroke about medicines and adherence. Positive beliefs were less common and negative more common among non-adherent. To improve adherence, patients' beliefs about medicines should be considered.

Further, patients in the youngest age group and patients with no CVD were less adherent to statin treatment. CONCLUSION......: We find some indication that risk attitude is associated with adherence to statin treatment, and that risk-neutral and risk-seeking patients may have poorer adherence than risk-averse patients. This is important for clinicians to consider when discussing optimal treatment decisions...... on the association between risk attitude and adherence. The aim of the present study was to estimate associations between patients' adherence to statin treatment and different dimensions of risk attitude, and to identify subgroups of patients with poor adherence.

    To develop a new questionnaire with good psychometric properties to measure satisfaction with medical care in patients with non-valvular atrial fibrillation. The initial instrument was composed of 37 items, arranged in 6 dimensions: efficacy, ease and convenience, impact on daily activities, satisfaction with medical care, undesired effects of medication, and overall satisfaction. Items and dimensions were extracted from reviewing existing instruments, 3 focus groups with chronic patients, and a panel of 8 experts. Additionally, 3 visual analog scales measuring quality of life, effectiveness, and overall satisfaction were administered. A convenience sample of 119 patients was used for item reduction. Classic psychometric theory and item analysis techniques were used (exploratory factor and confirmatory factor analysis, test-retest, and correlation with visual scales). A validation sample of 230 patients was used to assess convergent validity, and an additional 220 patients sample was used to discriminate between treatment and compliance groups. The questionnaire was reduced in length to 25 items, but the impact dimension had split in treatment inconvenience and treatment control. Overall reliability was high (α = 0.861) with acceptable dimensional reliabilities (α = 0.764-0.908). Individual dimensions correlated to varying degrees. Test-retest correlations were high (r = 0.784-0.965), and correlations with visual and already validated scales were substantial. Differences were detected between antivitamin K and new-oral-anticoagulant treatments in several dimensions (p satisfaction was related with compliance. This new 25-item questionnaire has good psychometric properties for measuring satisfaction with medical care in patients with this condition. It is capable of detecting differences between different treatments.

    Skeletal muscle mitochondrial protein synthesis is regulated in part by insulin. The development of insulin resistance with diet-induced obesity may therefore contribute to impairments to protein synthesis and decreased mitochondrial respiration. Yet the impact of diet-induced obesity and insulin resistance on mitochondrial energetics is controversial, with reports varying from decreases to increases in mitochondrial respiration. We investigated the impact of changes in insulin sensitivity on long-term rates of mitochondrial protein synthesis as a mechanism for changes to mitochondrial respiration in skeletal muscle. Insulin resistance was induced in C57BL/6J mice using 4 wk of a high-fat compared with a low-fat diet. For 8 additional weeks, diets were enriched with pioglitazone to restore insulin sensitivity compared with nonenriched control low-fat or high-fat diets. Skeletal muscle mitochondrial protein synthesis was measured using deuterium oxide labeling during weeks 10-12 High-resolution respirometry was performed using palmitoyl-l-carnitine, glutamate+malate, and glutamate+malate+succinate as substrates for mitochondria isolated from quadriceps. Mitochondrial protein synthesis and palmitoyl- l-carnitine oxidation were increased in mice consuming a high-fat diet, regardless of differences in insulin sensitivity with pioglitazone treatment. There was no effect of diet or pioglitazone treatment on ADP-stimulated respiration or H 2 O 2 emission using glutamate+malate or glutamate+malate+succinate. The results demonstrate no impairments to mitochondrial protein synthesis or respiration following induction of insulin resistance. Instead, mitochondrial protein synthesis was increased with a high-fat diet and may contribute to remodeling of the mitochondria to increase lipid oxidation capacity. Mitochondrial adaptations with a high-fat diet appear driven by nutrient availability, not intrinsic defects that contribute to insulin resistance. Copyright © 2017 the

    Objective: To investigate the β-cell function status and possible mechanism of insulin resistance in patients with type 2 diabetes through studies on the changes of serum APN, insulin, CRP, leptin, insulin antibody and glutamic acid decarboxylase antibody (GAD-Ab) levels after one year of treatment. Methods: Serum levels of the above four parameters and the positive rate of the two antibodies were measured (with CLIA, ELISA and RIA as appropriately) in 184 patients with type 2 diabetes and 30 controls as well as in 75 patients after one year of treatment. Results: The serum contents of insulin, leptin, CRP, insulin antibody in patients with type 2 diabetes were significantly higher (P<0.01) and APN levels significantly lower (P<0.001) than those in controls. Levels of APN were negatively correlated with those of the other parameters. In the 75 treated patients, levels of those parameters (with the exception of APN and insulin-antibody) decreased significantly. However, the APN levels were significantly increased (vs before treatment, P<0.001). Conclusion: Further study on the dynamic changes of these parameters in the diabetic patients might elucidate certain key-points in the pathogenesis of the disease. (authors)

    The administration of testosterone to pregnant sheep to resemble fetal programming of the polycystic ovary syndrome could alter other hormones/factors of maternal origin with known effects on fetal growth. Hence, we studied the weekly profile of insulin, progesterone and glucose during a treatment with testosterone propionate given biweekly from weeks 5 to 17 of pregnancy (term at 21 weeks) and checked the outcome of their fetuses at 17 weeks of gestation after C-section. Control dams were only exposed to the vehicle of the hormone. The testosterone administration did not cause any significant change in the maternal weekly profile of insulin, progesterone or glucose concentration, although the plasma levels of testosterone in the treated dams were inversely correlated to the levels of progesterone. Testosterone treatment also induced an inverse correlation between mean maternal insulin levels and fetal insulin levels; however, the fetal zoometric parameters, body weight, or insulin levels did not differ between exposed and not exposed fetuses. Therefore, treatment with testosterone during pregnancy does not cause significant impact on insulin levels in the mother, leading to less effect on the programming of fetal growth.

    The aim of the present study was to assess the efficacy of structured education in insulin-treated type 2 diabetes mellitus (T2DM) patients. In a 16-week open-label randomized controlled study, 1511 T2DM patients with inadequate responses to two or more oral antidiabetic drugs (OADs) for >3 months (HbA1c >7.5%) were randomized (1:1) to either an education group (structured diabetes education plus insulin therapy) or a control group (usual care plus insulin therapy). Both groups discontinued previous OADs (except biguanides and α-glucosidase inhibitors) and started twice daily injections of 30% soluble-70% isophane recombinant insulin. The primary endpoint was the change in HbA1c from baseline. Efficacy and safety data were analyzed for within- and between-group differences. Of the initial 1511 patients, 1289 completed the study (643 in the control group; 646 in the education group). At the end of the study, significant reductions in HbA1c versus baseline were evident in both groups, but the reduction was greater in the education group (2.16% vs. 2.08%; P patients in the education group achieved target HbA1c levels patients in the education group showed greater increments in scores and improvement in the Morisky Medication Adherence Scale (P education can promote the ability of patients to self-manage and their compliance with medications, thereby achieving better outcomes. © 2013 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

    Full Text Available PurposeGonadotropin-releasing hormone agonist (GnRHa is used as a therapeutic agent for central precocious puberty (CPP; however, increased obesity may subsequently occur. This study compared body mass index (BMI and insulin resistance during the first year of GnRHa treatment for CPP.MethodsPatient group included 83 girls (aged 7.0–8.9 years with developed breasts and a peak luteinizing hormone level of ≥5 IU/L after GnRH stimulation. Control group included 48 prepubertal girls. BMI and insulin resistance-related indices (homeostasis model assessment of insulin resistance [HOMA-IR] and quantitative insulin sensitivity check index [QUICKI] were used to compare the groups before treatment, and among the patient group before and after GnRHa treatment.ResultsNo statistical difference in BMI z-score was detected between the 2 groups before treatment. Fasting insulin and HOMA-IR were increased in the patient group; fasting glucose-to-insulin ratio and QUICKI were increased in the control group (all P<0.001. In normal-weight subjects in the patient group, BMI z-score was significantly increased during GnRHa treatment (−0.1±0.7 vs. 0.1±0.8, P<0.001, whereas HOMA-IR and QUICKI exhibited no differences. In overweight subjects in the patient group; BMI z-score and HOMA-IR were not significantly different, whereas QUICKI was significantly decreased during GnRHa treatment (0.35±0.03 vs. 0.33±0.02, P=0.044.ConclusionGirls with CPP exhibited increased insulin resistance compared to the control group. During GnRHa treatment, normal-weight individuals showed increased BMI z-scores without increased insulin resistance; the overweight group demonstrated increased insulin resistance without significantly altered BMI z-scores. Long-term follow-up of BMI and insulin resistance changes in patients with CPP is required.

    Satisfaction with treatment is considered a relevant factor for assessing results in clinical practice. However, when assessing satisfaction in dependent patients, the opinion of their caregivers becomes crucial, since implicit in satisfaction is the degree of caregiver involvement, of adherence to treatment, and lastly of better care of these patients. The purpose of this study was to develop, validate, and administer two versions of a specific questionnaire to assess satisfaction with blood glucose-lowering treatment in caregivers of dependent type 2 diabetic patients. This was an observational, descriptive, epidemiological study conducted in the Los Montalvos Internal Medicine Department at the University Hospital of Salamanca (Spain). Two versions of the questionnaire to assess caregivers' satisfaction with current treatment and after introducing changes in therapy were created and validated according to model procedures. Once validated, the questionnaires were implemented in 219 cases. Cronbach's α-coefficient, correlation between all the items, intraclass correlation coefficient, and correlation between the obtained scores and satisfaction with blood glucose levels all satisfied the standard for validation. Significant levels of correlation were observed between the degree of satisfaction and the number of daily administrations of the blood glucose-lowering medication (Spearman's r=-0.21, Ppatients receiving more frequent administration of their antidiabetic medication prior to the change were more satisfied with the change (r=0.24, Psatisfaction (r=-0.43, Psatisfaction was validated. When applied to our cohort of cases, the obtained data suggest that simplicity in antidiabetic therapy should be considered in the management of dependent type 2 diabetic patients when caregivers' satisfaction is an additional objective.

    To report the psychometrics of the Glaucoma Treatment Compliance Assessment Tool (GTCAT), a new questionnaire designed to assess adherence with glaucoma therapy. We developed the questionnaire according to the constructs of the Health Belief Model. We evaluated the questionnaire using data from a cross-sectional study with focus groups (n = 20) and a prospective observational case series (n=58). Principal components analysis provided assessment of construct validity. We repeated the questionnaire after 3 months for test-retest reliability. We evaluated predictive validity using an electronic dosing monitor as an objective measure of adherence. Focus group participants provided 931 statements related to adherence, of which 88.7% (826/931) could be categorized into the constructs of the Health Belief Model. Perceived barriers accounted for 31% (288/931) of statements, cues-to-action 14% (131/931), susceptibility 12% (116/931), benefits 12% (115/931), severity 10% (91/931), and self-efficacy 9% (85/931). The principal components analysis explained 77% of the variance with five components representing Health Belief Model constructs. Reliability analyses showed acceptable Cronbach's alphas (>.70) for four of the seven components (severity, susceptibility, barriers [eye drop administration], and barriers [discomfort]). Predictive validity was high, with several Health Belief Model questions significantly associated (P <.05) with adherence and a correlation coefficient (R (2)) of .40. Test-retest reliability was 90%. The GTCAT shows excellent repeatability, content, construct, and predictive validity for glaucoma adherence. A multisite trial is needed to determine whether the results can be generalized and whether the questionnaire accurately measures the effect of interventions to increase adherence.

    The European Organisation for Research and Treatment of Cancer quality of life (EORTC QL) questionnaires are used in international trials and therefore standardised translation procedures are required. This report summarises the EORTC translation procedure, recent accomplishments and challenges. Translations follow a forward-backward procedure, independently carried out by two native-speakers of the target language. Discrepancies are arbitrated by a third consultant, and solutions are reached by consensus. Translated questionnaires undergo a pilot-testing. Suggestions are incorporated into the final questionnaire. Requests for translations originate from the module developers, physicians or pharmaceutical industry, and most translations are performed by professional translators. The translation procedure is managed and supervised by a Translation Coordinator within the EORTC QL Unit in Brussels. To date, the EORTC QLQ-C30 has been translated and validated into more than 60 languages, with further translations in progress. Translations include all major Western, and many African and Asian languages. The following translation problems were encountered: lack of expressions for specific symptoms in various languages, the use of old-fashioned language, recent spelling reforms in several European countries and different priorities of social issues between Western and Eastern cultures. The EORTC measurement system is now registered for use in over 9000 clinical trials worldwide. The EORTC provides strong infrastructure and quality control to produce robust translated questionnaires. Nevertheless, translation problems have been identified. The key to improvements may lie in the particular features and strengths of the group, consisting of researchers from 21 countries representing 25 languages and include the development of simple source versions, the use of advanced computerised tools, rigorous pilot-testing, certification procedures and insights from a unique cross

    The aim of the study is to compare the effects of metformin and insulin treatment for gestational diabetes mellitus (GDM) on vitamin B12 and homocysteine (Hcy) status. Women with GDM, who met criteria for insulin treatment, were randomly assigned to metformin (n = 89) or insulin (n = 91) in the Adelaide cohort of the metformin in gestational diabetes (MiG) trial. Fasting serum total vitamin B12 (TB12), holotranscobalamin (HoloTC), a marker of functional B12 status and plasma Hcy concentrations were measured at 20-34 weeks (at randomization) and 36 weeks gestation, then at 6-8 weeks postpartum. Circulating TB12, HoloTC and Hcy were similar in both treatment groups at each time point. Women who were taking dietary folate supplements at randomization had higher serum TB12 and HoloTC at randomization than those not taking folate. Overall, serum TB12 fell more between randomization and 36 weeks gestation in the metformin group than in the insulin group (metformin: -19.7 ± 4.7 pmol/l, insulin: -6.4 ± 3.6 pmol/l, p = 0.004). The decrease in serum TB12 during treatment was greater with increasing treatment duration in metformin-treated (p pregnancy to a greater extent in metformin-treated than in insulin-treated women with GDM, but neither analyte differed between groups at any stage. This adds further evidence supporting metformin as a safe alternative treatment to insulin in GDM. Further investigation is needed to evaluate whether women treated with metformin for longer periods in pregnancy require additional B12 or other supplementation. © 2013 Blackwell Publishing Ltd.

    Full Text Available Background: Maintenance of stable glycemic control is an important prerequisite of effective treatment of patients with type 1 diabetes mellitus (DM. The ultra-long-acting basal insulin degludec allows for reduction of glycemic variability and for a substantial reduction in the rates of hypoglycemia with equivalent glycemic control. Evaluation of the impact of this novel insulin on diabetes-dependent quality of life and patient satisfactions with the treatment is necessary for comprehensive assessment of treatment efficacy.Aim: To study changes of glycated hemoglobin (HbA1c, rates of hypoglycemia, diabetes-dependent quality of life and treatment satisfaction in patients with type 1 DM, who have been switched to insulin degludec.Materials and methods: This open 12-week observational comparative study included 25  patients with type  1 DM (median age, 36 [20; 63] years, who were switched to insulin degludec in combination with a  ultra-short insulin analogue. The control group included 21 patients with type 1 DM (median age, 40 [23; 63] years, who continued their treatment with a long-acting insulin analogue glargine. At baseline and at week 12 after switching to insulin degludec, we assessed HbA1c level, mean insulin dose, depression score, diabetes-dependent quality of life and patient satisfaction with the treatment with the use of the Russian versions of the diabetes-specific questionnaires “Audit of Diabetes-Dependent Quality of life” (RuADDQoL, and “Diabetes Treatment Satisfaction Questionnaire” (DTSQ, respectively.Results: At 3 months, there was a significant reduction of the HbA1c levels in the main and the control groups to 7.57% (Ме 7.5 [7.1; 8.4]; р=0.03 and 8.18% (Ме 7.8% [7.4; 8.7]; р=0.04, respectively. The mean reduction of this parameter under treatment with degludec was slightly higher than under treatment with glargine (0.73 vs 0.57%, respectively, at 3 months the difference being statistically

    To compare the effects of metformin with insulin on maternal and neonatal outcomes in gestational diabetes mellitus (GDM). A literature search in PUBMED, EMBASE, Science Direct, Springer link, and Cochrane library was conducted using the following search terms: "Gestational Diabetes" or "GDM", and "insulin" and "metformin". Quality assessment of included studies was determined with Quality Assessment of Diagnostic Accuracy Studies. Review Manger 5.2 was used to analyze mean difference (MD)/risk ratio (RR) and 95 % confidence interval (CI) in random-effects model or fixed-effects model depending on the level of heterogeneity. A total of 11 studies were identified. There was no significant difference of the effect on maternal outcomes between the two treatments in glycohemoglobin A1c levels (P = 0.37), fasting blood glucose (P = 0.66), and the incidence of preeclampsia (P = 0.26); whereas, significantly reduced results were found in the metformin group in pregnancy-induced hypertension (PIH) rate (RR = 0.53, 95 % CI 0.31-0.90, P = 0.02), average weight gains after enrollment (MD = -1.28, 95 % CI -1.54 to -1.01, P metformin presented significantly lower average birth weights (MD = -44.35, 95 % CI -85.79 to -2.90, P = 0.04), incidence of hypoglycemia (RR = 0.69, 95 % CI 0.55-0.87, P = 0.001) and neonatal intensive care unit (NICU) (RR = 0.82, 95 % CI 0.67-0.99, P = 0.04). Metformin can significantly reduce several adverse maternal and neonatal outcomes including PIH rate, incidence of hypoglycemia and NICU, thus it may be an effective and safe alternative or additional treatment to insulin for GDM women.

    Background: The PaQ® insulin delivery system is a simple-to-use patch-on device that provides preset basal rates and bolus insulin on demand. In addition to feasibility of use, safety, and efficacy (reported elsewhere), this study analyzed the impact of PaQ on patient-reported outcomes, including barriers to insulin treatment, diabetes-related distress, and attitudes toward insulin therapy in patients with type 2 diabetes on a stable multiple daily injection (MDI) regimen. Methods: This single-center, open-label, single-arm study comprised three 2-week periods: baseline (MDI), transition from MDI to PaQ, and PaQ treatment. Validated questionnaires were administered during the baseline and PaQ treatment periods: Barriers to Insulin Treatment questionnaire (BIT), Insulin Treatment Appraisal Scale (ITAS), and Problem Areas in Diabetes scale (PAID). Results: Eighteen patients (age 59 ± 5 years, diabetes duration 15 ± 7 years, 21% female, HbA1c 7.7 ± 0.7%) completed the questionnaires. There was a strong, significant effect of PaQ use in mean BIT total scores (difference [D] = −5.4 ± 0.7.7, P = .01, effect size [d] = 0.70). Patients perceived less stigmatization by insulin injection (D = −2.2 ± 6.2, P = .18, d = 0.35), increased positive outcome (D = 1.9 ± 6.6, P = .17, d = 0.29), and less fear of injections (1.3 ± 4.8, P = .55, d = 0.28). Mean change in ITAS scores after PaQ device use showed a nonsignificant improvement of 1.71 ± 5.63 but moderate effect size (d = 0.30, P = .14). No increase in PAID scores was seen. Conclusions: The results and moderate to large effects sizes suggest that PaQ device use has beneficial and clinically relevant effects to overcoming barriers to and negative appraisal of insulin treatment, without increasing other diabetes-related distress.

    Continuous subcutaneous insulin infusion (CSII) via personal insulin pump is a valuable therapeutic tool in T1DM patients. However, adherence to recommended CSII-related behaviours may be of concern to young adults with intensive, variable daily activities (students, young professionals). The aim of this observational study was to estimate treatment outcomes in young adult patients with T1DM, and compare them with older individuals. Overall, 140 adults with T1DM on CSII were examined, divided into 2 subgroups: 77 patients younger than 26 years of age (mean 20.6 years) and 63 older subjects (mean 39.0). We compared the glycaemic control in both groups of T1DM subjects and analyzed treatment attitudes to identify potentially modifiable behaviours influencing the efficacy of the treatment. The younger individuals were characterized by significantly worse treatment outcomes, compared to the older ones: the mean HbA1c levels were 7.6 ± 1.3% and 6.9±1.3% (p=0.00001), while the mean glucose levels based on glucometer downloads were 161±33.6 mg/dL and 136±21.8 mg/dL (p=0.00001), respectively. The frequency of self-monitoring of blood glucose (SMBG) was lower in younger individuals (5.3±2.1 vs. 7.0±2.8 daily, p=0.0005, respectively); they were also less frequently used advanced pump functions, e.g. the bolus calculator (48% vs. 67% users, p=0.0014, respectively). The efficacy of CSII treatment observed in young T1DM adults was worse than in older patients. The reason for this phenomenon remains unclear, it may be due simply to age-dependend behaviours, to social environment, or both.

    Background : Treatment research for dissociative identity disorder (DID) and closely related severe dissociative disorders (DD) is rare, and has been made more difficult by the lack of a reliable, valid measure for assessing treatment progress in these populations. Objective : This paper presents psychometric data for therapist and patient report measures developed to evaluate therapeutic progress and outcomes for individuals with DID and other DD: the Progress in Treatment Questionnaire - Therapist (PITQ-t; a therapist report measure) and the Progress in Treatment Questionnaire - Patient (PITQ-p; a patient self-report measure). Method : We examined the data of 177 patient-therapist pairs (total N  = 354) participating in the TOP DD Network Study, an online psychoeducation programme aimed at helping patients with DD establish safety, regulate emotions, and manage dissociative and posttraumatic symptoms. Results : The PITQ-t and PITQ-p demonstrated good internal consistency and evidence of moderate convergent validity in relation to established measures of emotional dysregulation, dissociation, posttraumatic stress disorder, and psychological quality of life, which are characteristic difficulties for DD patients. The measures also demonstrated significant relationships in the hypothesized directions with positive emotions, social relations, and self-harm and dangerous behaviours. The patient-completed PITQ-p, which may be used as an ongoing assessment measure to guide treatment planning, demonstrated evidence of stronger relationships with established symptom measures than the PITQ-t. Conclusions : The PITQ-t and PITQ-p merit use, additional research, and refinement in relation to the assessment of therapeutic progress with patients with DD.

  12. SGLT2 inhibitors – an insulin-independent therapeutic approach for treatment of type 2 diabetes: focus on canagliflozin

    2015-11-01

    Full Text Available Jochen SeufertDepartment of Endocrinology and Diabetology, Clinic for Internal Medicine II, Freiburg University Hospital, Freiburg, GermanyAbstract: Despite the availability of a great variety of medications, a significant proportion of people with type 2 diabetes mellitus (T2DM are not able to achieve or maintain adequate glycemic control. Beyond improved glucose control, novel treatments would ideally provide a reduction of cardiovascular risk, with a favorable impact on excess weight, and a low intrinsic hypoglycemia risk, as well as a synergistic mechanism of action for broad combination therapy. With the development of sodium glucose cotransporter 2 (SGLT2 inhibitors, an antidiabetic pharmacologic option has recently become available that comes close to meeting these requirements. For the first time, SGLT2 inhibitors offer a therapeutic approach acting directly on the kidneys without requiring insulin secretion or action. Canagliflozin, dapagliflozin, and empagliflozin are the SGLT2 inhibitors approved to date. Taken once a day, these medications can be combined with all other antidiabetic medications including insulin, due to their insulin-independent mechanism of action, with only a minimal risk of hypoglycemia. SGLT2 inhibitors provide additional reductions in body weight and blood pressure due to the therapeutically induced excretion of glucose and sodium through the kidneys. These "concomitant effects" are particularly interesting with regard to the increased cardiovascular risk in T2DM. In many cases, T2DM treatment requires a multidimensional approach where the treatment goals have to be adapted to the individual patient. While there is a consensus on the use of metformin as a first-line drug therapy, various antidiabetics are used for treatment intensification. New mechanisms of action like that of SGLT2 inhibitors such as canagliflozin, which can be used both in early and late stages of diabetes, are a welcome addition to expand

    Type 2 diabetes mellitus (T2DM) is a chronic metabolic disease associated with multiple macro and microvascular complications, diabetic retinopathy (DR) being the commonest one. Recent literature has reported an increased risk of DR with insulin use. We carried out a cross-sectional study at the Ophthalmology Department of the Douala General Hospital (DGH) during a 2-year period to explore the association between insulin treatment and both DR and its severity as compared with oral hypoglycemic agents (OHAs) in Cameroonian T2DM patients aged ≥35 years, and who were all screened for DR through eye examination including exhaustive retinal evaluation. In total, medical files of 134 T2DM patients were analyzed. The frequency of DR was 54.1% among patients on OHA and 73.9% among those on insulin treatment, giving an overall frequency of 57.5%. There were significantly more OHA treated patients than insulin treated patients (82.8% vs . 17.2%, Phistory of hypertension, alcohol misuse, and current tobacco smoking. DR was almost significantly more frequent in T2DM patients under insulin regimen than in patients under OHA [73.9% vs . 54.1%; odds ratio (OR) 2.4; 95% confidence interval (CI), 0.9-6.6; P=0.06]. Proliferative diabetic retinopathy (PDR) was significantly more observed in insulin treated patients than in OHA treated patients (34.8% vs . 15.3%; OR 2.95; 95% CI, 1.1-8; P=0.035). Irrespective of staging, the frequency of diabetic macular edema (DME) was significantly higher in the insulin group than in the OHA group (43.5% vs . 19.8%; OR 3.1; 95% CI, 1.2-8; P=0.019). Compared with OHA, insulin therapy may be associated with DR, DR severity and DME in these T2DM sub-Saharan African patients.

    Full Text Available Insulin-Like Growth Factor 1 (IGF-1 is a neurotrophic polypeptide with crucial roles to play in Central Nervous System (CNS growth, development and maturation. Following interrogation of the neurobiology underlying several neurodevelopmental disorders and Autism Spectrum Disorders (ASD, both recombinant IGF-1 (mecasermin and related derivatives, such as (1-3 IGF-1, have emerged as potential therapeutic approaches. Clinical pilot studies and early reports have supported the safety/preliminary efficacy of IGF-1 and related compounds in the treatment of Rett Syndrome, with evidence mounting for its use in Phelan McDermid Syndrome and Fragile X Syndrome. In broader ASD, clinical trials are ongoing. Here, we review the role of IGF-1 in the molecular etiologies of these conditions in addition to the accumulating evidence from early clinical studies highlighting the possibility of IGF-1 and related compounds as potential treatments for these childhood-onset neurodevelopmental disorders.

    Obestatin and ghrelin are peptides encoded by the preproghrelin gene. Obestatin inhibits food intake, in addition to regulation of glucose and lipid metabolism. Here, we test the ability of obestatin at improving metabolic control and liver function in type 2 diabetic animals (type 2 diabetes mellitus). The effects of chronic obestatin treatment of mice with experimentally induced type 2 diabetes mellitus on serum levels of glucose and lipids, and insulin sensitivity are characterized. In addition, alterations of hepatic lipid and glycogen contents are evaluated. Obestatin reduced body weight and decreased serum glucose, fructosamine, and β-hydroxybutyrate levels, as well as total and low-density lipoprotein fractions of cholesterol. In addition, obestatin increased high-density lipoproteins cholesterol levels and enhanced insulin sensitivity in mice with type 2 diabetes mellitus. Moreover, obestatin diminished liver mass, hepatic triglycerides and cholesterol contents, while glycogen content was higher in livers of healthy and mice with type 2 diabetes mellitus treated with obestatin. These changes were accompanied by reduction of increased alanine aminotransferase, aspartate aminotransferase, and gamma glutamyl transpeptidase in T2DM mice with type 2 diabetes mellitus. Obestatin increased adiponectin levels and reduced leptin concentration. Obestatin influenced the expression of genes involved in lipid and carbohydrate metabolism by increasing Fabp5 and decreasing G6pc, Pepck, Fgf21 mRNA in the liver. Obestatin increased both, AKT and AMPK phosphorylation, and sirtuin 1 (SIRT1) protein levels as well as mRNA expression in the liver. Obestatin improves metabolic abnormalities in type 2 diabetes mellitus, restores hepatic lipid contents and decreases hepatic enzymes. Therefore, obestatin could potentially have a therapeutic relevance in treating of insulin resistance and metabolic dysfunctions in type 2 diabetes mellitus.

    The purpose of the paper was to present the results of surgical treatment of foot deformities in peripheral neuropathies using bone procedures: both joint preserving and with joint arthrodesis. The study included 26 patients, 14 males and 12 females (43 feet). The age of the patients at surgery ranged from 5 to 55 years (average 23 years). The follow-up ranged from 0.5 to 15 years (average 4.3 years). Seventeen patients presented Charcot-Marie-Tooth disease, three Friedreich's ataxia and six peripheral motor and sensory neuropathies of undetermined nature. Sixteen patients had bilateral procedures. Four patients had to be re-operated during the follow-up. The patients were divided into four groups depending on the age and the surgical technique applied. The groups I and II (9 children, 17 feet) included patients with growth plate still present in the foot just before surgery. In the groups III and IV (17 adults, 26 feet), bone growth was completed. The assessment of all patients based on a modified AOFAS scale ranged from 44 to 105 points (mean 83.7; SD 17.5). The assessment on the subjective scale ranged from 3 to 10 points (mean 7.4; SD 2.1). The assessment of quality of life on the WOMAC scale ranged from 0 to 41 points (mean 15.7; SD 13.2). All patients stated that they would decide to undergo the treatment again. For groups I and II, joint preserving surgeries gave better results; however, the results could not be statistically confirmed. The results for the groups III and IV were inconclusive as to which surgical techniques should be preferred, arthrodesis or joint preserving. The results show that none of the surgical techniques used for correction of foot deformities in motor-sensory polyneuropathies seems to be preferable.

    Menopause is associated with an increased incidence of insulin resistance and metabolic diseases. In a chronic palmitate treatment model, we investigated the role of skeletal muscle fatty acid exposure in relation to the metabolic deterioration observed with menopause. Human skeletal muscle......, post-myotubes showed a blunted insulin stimulated phosphorylation of AS160 in response to chronic palmitate treatment compared with pre-myotubes (p = 0.02). The increased intramyocellular ceramide content in the post-myotubes was associated with a significantly higher mRNA expression of Serine...... Palmitoyltransferase1 (SPT1) after one day of palmitate treatment (p = 0.03) in post-myotubes compared with pre-myotubes. Our findings indicate that post-myotubes are more prone to develop lipid accumulation and defective insulin signaling following chronic saturated fatty acid exposure as compared to pre-myotubes....

    Although subcutaneous treatments for multiple sclerosis (MS) have been shown to be effective, adverse reactions and pain may adversely affect treatment satisfaction and adherence. This study presents an adapted and validated Spanish version of the Multiple Sclerosis Treatment Concerns Questionnaire © (MSTCQ), which evaluates satisfaction with the injection device (ID) across 4 domains: injection system (A), side effects (B) (flu-like symptoms, reactions, and satisfaction), experience with treatment (C) and benefits (D). Two study phases: 1) Cultural adaptation process with input from experts (n=6) and patients (n=30). 2) Validation obtained by means of an observational, cross-sectional, multi-centre study evaluating 143 adult MS patients using an ID. Tools employed: MSTCQ © , Patient-Reported Indices for Multiple Sclerosis (PRIMUS © ), and Treatment Satisfaction Questionnaire for Medication (TSQM © ). Psychometric properties: Feasibility (percentage of valid cases and floor/ceiling effects); Reliability (Cronbach α) and test-retest correlation (n=41, intraclass correlation coefficient, ICC); and construct validity (factor analysis of domains A and B) and convergent validity (Spearman rank-order correlation for MSTCQ © vs TSQM © ). Mean age (SD) was 41.94 (10.47) years, 63% of the group were women, and 88.11% presented relapsing-remitting MS. Mean (SD) EDSS score was 2.68 (1.82) points. MSTCQ © completion was high (0%-2.80% missing data). Internal consistency was high at α=0.89 for the total score (A+B) and α=0.76, 0.89, and 0.92 for domains A, B, and C, respectively. The version demonstrated excellent test-retest reliability for the total (ICC=0.98) and for domains A, B, and C: ICC=0.82, 0.97, and 0.89, respectively. Factor analysis corroborated the internal structure of the original questionnaire. The association between total and domain scores on both the MSTCQ © and the TSQM © was moderately strong (Rho=0.42-0.74) and significant (P<.05 and P<.01

    This study assessed the psychometric properties of a parent-reported tic severity measure, the Parent Tic Questionnaire (PTQ), and used the scale to establish guidelines for delineating clinically significant tic treatment response. Participants were 126 children ages 9 to 17 who participated in a randomized controlled trial of Comprehensive Behavioral Intervention for Tics (CBIT). Tic severity was assessed using the Yale Global Tic Severity Scale (YGTSS), Hopkins Motor/Vocal Tic Scale (HMVTS) and PTQ; positive treatment response was defined by a score of 1 (very much improved) or 2 (much improved) on the Clinical Global Impressions - Improvement (CGI-I) scale. Cronbach's alpha and intraclass correlations (ICC) assessed internal consistency and test-retest reliability, with correlations evaluating validity. Receiver- and Quality-Receiver Operating Characteristic analyses assessed the efficiency of percent and raw-reduction cutoffs associated with positive treatment response. The PTQ demonstrated good internal consistency (α = 0.80 to 0.86), excellent test-retest reliability (ICC = .84 to .89), good convergent validity with the YGTSS and HM/VTS, and good discriminant validity from hyperactive, obsessive-compulsive, and externalizing (i.e., aggression and rule-breaking) symptoms. A 55% reduction and 10-point decrease in PTQ Total score were optimal for defining positive treatment response. Findings help standardize tic assessment and provide clinicians with greater clarity in determining clinically meaningful tic symptom change during treatment. Copyright © 2017.

    Full Text Available BACKGROUND: Hypertension is a global public health crisis. Poorly controlled high blood pressure is one of the major factors contributed to this crisis. As lack of treatment adherence is often considered the main reason for this failure, the Treatment Adherence Questionnaire for Patient with Hypertension (TAQPH was developed. Since this questionnaire should be reliable and strongly valid to be used in clinics and research, this study was performed to test the reliability and validity of the TAQPH. METHODS: A cross-sectional study was conducted to validate the Persian version of TAQPH after using a modified forward/backward translation procedure. A total of 330 hypertensive patients were participated in this study. Construct and criterion validity, Cronbach¢s alpha, and test-retest reliability were used to validate the Persian scale. RESULTS: Data analysis showed that the scale had excellent stability (intraclass correlation = 0.95 and good acceptability of internal consistency (α = 0.80. The exploratory factor analysis (EFA was meaningful but was not confirmed with confirmatory factor analysis (CFA. The scale score was correlated with Morisky Medication Adherence Scale (MMAS score (Ρ = 0.27. CONCLUSION: In total, most of the psychometric properties of the 25-item P-TAQHP achieved the standard level and were sufficient to recommend for general use.

    The metabolic and hormonal adaptations to single exercise sessions and to exercise training in normal man and in patients with insulin-dependent as well as non-insulin-dependent diabetes mellitus are reviewed. In insulin-dependent (type I) diabetes good metabolic control is best obtained...... by a regular pattern of life which will lead to a fairly constant demand for insulin from day to day. Exercise is by nature a perturbation that makes treatment of diabetes difficult: Muscle contractions per se tend to decrease the plasma glucose concentration whereas the exercise-induced response of the so......-called counter-regulatory hormones tend to increase plasma glucose by increasing hepatic glucose production and adipose tissue lipolysis.

    Controversial results have been found in literature for the association between insulin resistance and sustained virologic response to standard chronic hepatitis C treatment. This study aims to provide a systematic literature review with meta-analysis, in order to evaluate if insulin resistance interferes with sustained virologic response in patients infected by the HCV genotype 1 versus HCV genotypes 2 and 3, undergoing treatment with interferon and ribavirin or pegylated interferon and ribavarin. Systematic search was performed on main electronic databases until May 2012. Primary outcome was sustained virologic response, defined as undetectable levels of HCV-RNA six months after the end of treatment. Meta-analytic measure was estimated using Dersimonian and Laird's method, using Stata software. Thirteen studies involving 2238 infected patients were included. There was a statistically significant association between insulin resistance and lower sustained virologic response rate, and this difference occurred in HCV genotype G1 (OR: 2.23; 95% CI: 1.59-3.13) and G2/G3 (OR: 4.45; 95% CI: 1.59-12.49). In addition, a difference was seen in the cut-offs used for defining insulin resistance by Homeostasis Model Assessment of Insulin Resistance. To minimize this limitation, sub-analysis that excluded the studies that did not use 2 as a cut-off value was performed and the results still demonstrated association between insulin resistance and sustained virologic response, for both genotypic groups. This meta-analysis provides evidence that elevated Homeostasis Model Assessment of Insulin Resistance is associated with a lower sustained virologic response rate in patients with hepatitis C treated with interferon and ribavirin or pegylated interferon and ribavarin, regardless of their genotype.

    Growth-enhancing hormone treatment is considered a possible intervention in short but otherwise healthy adolescents. Although height gain is an obvious measure for evaluating hormone treatment, this may not be the ultimate goal for the person, but rather a means to reach other goals such as the amelioration of current height-related psychosocial problems or the enhancement of future prospects in life and society. The aim of our study was to clarify the motives of adolescents and their parents when choosing to participate in a growth-enhancing trial combining growth hormone and puberty-delaying hormone treatment. Participants were early pubertal adolescents (25 girls, 13 boys) aged from 11 to 13 years (mean age 11.5 years) with a height standard deviation score (SDS) ranging from -1.03 to -3.43. All had been classified as idiopathic short stature or persistent short stature born small for the gestational age (intrauterine growth retardation) on the basis of a height SDS below -2, or had a height SDS between -1 and -2 and a predicted adult height SDS below -2. The adolescents and their parents completed questionnaires and a structured interview on the presence of height-related stressors, parental worries about their child's behavior and future prospects, problems in psychosocial functioning, and treatment expectations. Questionnaire scores were compared to norms of the general Dutch population. The adolescents reported normal psychosocial functioning and highly positive expectations of the treatment in terms of height gain, whereas the parents reported that their children encountered some behavioral problems (being anxious/depressed, and social and attention problems) and height-related stressors (being teased and juvenilized). About 40% of the parents were worried about their children's future prospects for finding a spouse or job. The motives of the adolescents and their parents exhibited rather different profiles. The most prevalent parental worries related to

    Full Text Available In the current study, we used immunoprecipitation and immunoblotting to examine the levels and phosphorylation status of the insulin receptor-beta subunit (IR-β, as well as the down stream target in PI3K pathway, total PKB/Akt as well as their phosphorylated forms. The assessment of FFAs treatment showed no direct and significant effect on the PI3K stimulation, specifically the IR-β in primary hepatic control cells treated with insulin. Cells treated with either oleate or palmitate (360 µM showed no statistically significant values following insulin stimulation (P > 0.05. To further investigate the effect of both FFAs and high insulin (1 µg, we examined the effects of oleate and palmitate at 360 µM concentration on IR-β as well as PKB. There was no significant difference in the total protein levels and their phosphorylated forms in cells treated with or without oleate or plamitate. Interestingly, IR-β tyrosine phosphorylation showed a similar insignificant effect in vivo and ex vivo hepatic cells treated with oleate or palmitate in comparison to their controls in the fructose fed hamsters.

    Our aim was to evaluate the insulin initiation status, barriers to insulin initiation and knowledge levels about treatment administered by primary care physicians (PCP). We conducted our study in accordance with a multicenter, cross-sectional design in Turkey, between July 2015 and July 2016. A questionnaire inquiring demographic features, status of insulin initiation, obstacles to insulin initiation and knowledge about therapy of the PCPs was administered during face-to-face interviews. 84 PCPs (19%) (n=446, mean age=41.5±8.4years, 62.9% male and 90.0% ministry certified family physicians) initiated insulin therapy in the past. Most of the stated primary barriers (51.9%, n=230) were due to the physicians. The most relevant barrier was "lack of clinical experience" with a rate of 19% (n=84 of the total). The average total knowledge score was 5.7±2.0 for the family medicine specialist, and 3.8±2.1 for the ministry certified family physicians (p=0.000, maximum knowledge score could be 10). The status of insulin initiation in Turkey by the primary care physicians is inadequate. Medical education programs and health care systems may require restructuring to facilitate insulin initiation in primary care. Copyright © 2017 Primary Care Diabetes Europe.

    Facial lines or wrinkles are among the most visible signs of aging, and minimally invasive cosmetic procedures are becoming increasingly popular. The aim of this study was to develop and validate the Facial Line Satisfaction Questionnaire (FLSQ) for use in adults with upper facial lines (UFL). A literature review, concept elicitation interviews (n = 33), and cognitive debriefing interviews (n = 23) of adults with UFL were conducted to develop the FLSQ. The FLSQ comprises Baseline and Follow-up versions and was field-tested with 150 subjects in a US observational study designed to assess its psychometric performance. Analyses included acceptability (item and scale distribution [i.e. missingness, floor, and ceiling effects]), reliability, and validity (including concurrent validity). In total, 69 concepts were elicited during patient interviews. Following cognitive debriefing interviews, the FLSQ-Baseline version included 11 items and the Follow-up version included 13 items. Response rates for the FLSQ were 100% and 73% at baseline and follow-up, respectively; no items had excessive missing data. Questionnaire scale scores were normally distributed. Most domain scores demonstrated good internal consistency reliability (Cronbach's α ≥ 0.70). Most items within their respective domains exhibited good convergent (item-scale correlations > 0.40) and discriminant (items had higher correlation with their hypothesized scales than other scales) validity. Concurrent validity correlation coefficients of the FLSQ domain scores with the associated concurrent measures were acceptable (range: r = 0.40-0.70). Six FLSQ items demonstrated reliability and validity as stand-alone items outside their domains. The FLSQ is a valid questionnaire for assessing treatment expectations, satisfaction, impact, and preference in adults with UFL. © 2015 The Authors.

    Full Text Available Introduction: Clinical decision support systems (CDSS are computer systems designed to assist clinicians with patient-related decision making, such as diagnosis and treatment. CDSS have shown to improve both patient outcomes and cost of care.Methods: A multi-center observational prospective study was conducted. Ten physicians agreed to participate. Seventy-seven patients with high or very high cardiovascular risk were included. After using CDSS for dyslipidemia (HTE-DLPR for a 3 months period, participants were asked to evaluate their experience with HTE-DLPR using a quality of experience questionnaire (QoE tool for mHealth applications.Results: Total score on the QoE was 3.89 out of 5. The highest scores were received for precision, ease of use and content quality. The lowest scores were given to security, appearance and performance. Physicians were in strong agreement with the 1st HTEDLPR recommendation in 86.1% and the system’s use was described as comfortablein 85% of cases. Users positively evaluated the development of a new version of HTEDLPR in the future receiving a total score of 4.25 out of 5.Conclusions: A CDSS for dyslipidemia (HTE-DLP has been positively evaluated by physicians using QoE questionnaire.

    2008-03-01

    Laron syndrome (LS, congenital primary GH insensitivity) is caused by deletions or mutations in the GH receptor gene, resulting in an inability to generate insulin-like growth factor-I (IGF-I). If untreated, the deficiency of IGF-I results in severe dwarfism, as well as skeletal and muscular underdevelopment. The only treatment is the daily administration of recombinant IGF-I. This review summarizes the present experience by several groups worldwide. The main conclusions are: A. The one or two injections regimen result in the same growth velocity; B. The growth velocity obtained with IGF-I administration is smaller than that observed with hGH in children with congenital isolated GH deficiency; C. Overdosage of IGF-I causes a series of adverse effects which can be avoided by carefully monitoring the serum IGF-I and GH levels.

Epidemiologic, observational, multicenter, prospective (October 2008-February 2009) study in patients ≥40 years old with de novo overactive bladder syndrome who start treatment with antimuscarinics by physicians assessment. Data was recorded at baseline (face-to-face) and the follow-up of the study after 1 and 3 months (closed surveys by phone). Morisky-Green questionnaire was used to assess compliance. Bladder Control Self-assessment Questionnaire (B-SAQ) and BSW questionnaire were completed, performing the validation of BSW. 312 evaluable patients were recruited, 93 remained until the 3 months visit. 65% and 71% of patients were not compliant with treatment at 1 and 3 months, respectively. The correlation between the BSW and the B-SAQ questionnaires after 1 and 3 months was moderate and statistically significant. The internal consistency between the BSW questionnaire items was high (Cronbach alpha: 0,89 at 1 month and 0,84 at 3 months). 92% of patients understood the questions and 84% were able to fill the BSW questionnaire without need of previous instructions (N=25). The BSW questionnaire has been shown to be a feasible, valid and reliable tool to know the patient self-assessment of the treatment, according to its psychometric properties. Copyright © 2013 AEU.

    Bad Sobernheim Stress Questionnaire (BSSQ)-Deformity and BSSQ-Brace are the most widely used instruments for evaluating stress levels in adolescent idiopathic scoliosis (AIS) patients under brace treatment, and good reliability and validity have been demonstrated across different cultures. Great stress has been found among many adolescents, becoming a major concern for professionals. However, no previous research has addressed the cultural adaptations and psychometric testing of BSSQ-Deformity and BSSQ-Brace in China or the stress levels in AIS patients. The purposes of our study were to evaluate the cross-cultural adaptation and validation of the BSSQ-Deformity and BSSQ-Brace and to investigate stress levels in Chinese (AIS) patients under brace treatment.The original (German) versions of BSSQ-Deformity and BSSQ-Brace were cross-culturally translated according to international guidelines. Psychometric properties such as reliability and construct validity were tested. Eighty-six AIS patients were included in our study, and 50 patients paid a second visit 3 to 7 days later to test reproducibility. Cronbach α and the intraclass coefficient were determined to assess internal consistency and reproducibility. Scoliosis Research Society patient questionnaire-22 (SRS-22) was applied to evaluate construct validity.The mean BSSQ-Deformity and BSSQ-Brace scores were 15.3 and 13.4 points, respectively. Severe stress was observed in 12% of patients due to brace treatment. Item analysis demonstrated that each item was scored under a normal distribution with no redundancy. Psychometric analysis revealed excellent internal consistency (Cronbach α = 0.85 and 0.80, respectively) and reproducibility (intraclass correlation coefficient = 0.85 and 0.90, respectively) for BSSQ-Deformity and BSSQ-Brace. The correlation coefficients of BSSQ-Deformity, BSSQ-Brace and SRS-22 were 0.48 and 0.63, respectively.In conclusion, BSSQ-Deformity and BSSQ-Brace have been successfully

    Complementary and alternative medicine (CAM) is commonly used by children with juvenile idiopathic arthritis (JIA), yet no validated questionnaires assess that use. The objective of this study was to develop child self- and parent proxy-report questionnaires assessing CAM use and to determine the face and content validity of the "Which Health Approaches and Treatments are you using?" (WHAT) questionnaires in pediatric rheumatology. A sequential phased mixed methods approach was used to develop the questionnaires. A Delphi Survey of 126 experts followed by an interdisciplinary consensus conference of 14 stakeholders in CAM, general pediatrics and pediatric rheumatology was held to develop consensus on the content of the questionnaires using a nominal group technique. To determine face and content validity of the questionnaires, two groups, including (a) a purposive sample of 22 children with JIA 8 to 18 years and their parents from the Children's Hospital of Eastern Ontario and the Hospital for Sick Children, and (b) 21 Canadian pediatric rheumatology experts, participated in interviews. Participants were independently asked about the goal, understandability and comprehensiveness of the WHAT questionnaires, as well as the relevance of items. Consensus was reached on 17 items of the WHAT questionnaires. The domains found to be relevant were child's CAM use, factors associated with CAM use, perceived impact of CAM use, and communication about CAM. A total of 15 items in the parent proxy-report questionnaire and 13 items in the child report questionnaire showed adequate content validity. Consensus was reached by experts on the content of a pediatric CAM questionnaire.

    Full Text Available Background. The causes of decubitus ulcers include ischaemia and neurotrophic tissue changes induced by their chronic compression, continuous pathologic moisture and shift of tissues that determine local ishaemia. The aim of the article: to study clinical options and suppurative complications of decubitus ulcers in patients with type 2 diabetes mellitus (DM in terms of insulin resistance (IR in the context of combined treatment optimization. Materials and methods. Total sample of retro- and prospective analyses involved results of comprehensive treatment of 112 patients. Type 2 DM was diagnosed in 37 patients, I comparison group included 27 patients with decubitus ulcers without complications (I–III stages and DM, with decubitus ulcers stage IV — II comparison group; and the control group included other 75 individuals. Results. The patients with type 2 DM (I comparison group had considerable decrease in HOMA index of β-cell function and increased HOMA index of IR (8.31 ± 0.02, р < 0.01. Patients with type 2 DM with complicated decubitus ulcers (II comparison group had more significant increase of circulating insulin indexes (p2 < 0.01, HOMA index of IR (p2 < 0.05, and considerable decrease on HOMA index of β-cell function (p2 < 0.05. The correlation analysis of HOMA-IR indicators and element concentration in the blood revealed the correlation only in patients with type 2 DM (I and II comparison groups: potent negative correlation (r = –0.72; p < 0.001 was revealed between the HOMA-IR and Mg2+ content in erythrocytes; intermediate negative correlation (r = –0.66; p < 0.01 — between HOMA-IR and Zn2+ concentration in the blood serum; and a negative one (r = –0.69; p < 0.01 — between HOMA-IR and Cr3+ level in the blood serum. Conclusions. The advantage of the proposed classification of decubitus ulcers of soft tissue and a sequence of comprehensive treatment is considering the features of

    Full Text Available Abstract Background Growth-enhancing hormone treatment is considered a possible intervention in short but otherwise healthy adolescents. Although height gain is an obvious measure for evaluating hormone treatment, this may not be the ultimate goal for the person, but rather a means to reach other goals such as the amelioration of current height-related psychosocial problems or the enhancement of future prospects in life and society. The aim of our study was to clarify the motives of adolescents and their parents when choosing to participate in a growth-enhancing trial combining growth hormone and puberty-delaying hormone treatment. Methods Participants were early pubertal adolescents (25 girls, 13 boys aged from 11 to 13 years (mean age 11.5 years with a height standard deviation score (SDS ranging from -1.03 to -3.43. All had been classified as idiopathic short stature or persistent short stature born small for the gestational age (intrauterine growth retardation on the basis of a height SDS below -2, or had a height SDS between -1 and -2 and a predicted adult height SDS below -2. The adolescents and their parents completed questionnaires and a structured interview on the presence of height-related stressors, parental worries about their child's behavior and future prospects, problems in psychosocial functioning, and treatment expectations. Questionnaire scores were compared to norms of the general Dutch population. Results The adolescents reported normal psychosocial functioning and highly positive expectations of the treatment in terms of height gain, whereas the parents reported that their children encountered some behavioral problems (being anxious/depressed, and social and attention problems and height-related stressors (being teased and juvenilized. About 40% of the parents were worried about their children's future prospects for finding a spouse or job. The motives of the adolescents and their parents exhibited rather different profiles

    Diabetes mellitus, a major risk factor of atherosclerosis, is associated with the aortic accumulation of macromolecules. The authors have examined this relationship in the streptozotocin (STZ)-diabetic guinea pig, a species (like man) unable to synthesize ascorbic acid and susceptible to atherosclerosis. Male Dunkin-Hartley guinea pigs received STZ (150 mg/kg, i.c.) or vehicle (control). After 5 days, insulin (10 U/kg/day) was given to half the STZ animals (STZ-INS0 while the remaining half (STZ-SAL) and controls received saline. 25 days later, animals were given 125 I-albumin (100 μCi/kg, i.a.). Activity was determined in plasma at 5 (C/sub p5), 15 and 30 minutes, and in the upper thoracic aorta after 30 minutes. Histopathological changes were evaluated in the lower aorta. Aortic albumin permeability defined as cpm/cm 2 /sec, cpm/cm 2 /sec/C/sub p5/, or cpm/C/sub p5//g tissue was significantly elevated in the STZ-SAL group compared to both STZ-INS and control groups; these latter two groups were not significantly different from each other. Oil-Red-O positive material (lipid) occurred at multifocal areas within the intima of the STZ-SAL animals only. This study demonstrates (1) an abnormal increase in aortic permeability to albumin, (2) histological evidence of early atherosclerotic lesions, and (3) that insulin treatment can prevent these angiopathies in this STZ-diabetic animal model

  7. Oral treatment with γ-aminobutyric acid improves glucose tolerance and insulin sensitivity by inhibiting inflammation in high fat diet-fed mice.

    Full Text Available Adipocyte and β-cell dysfunction and macrophage-related chronic inflammation are critical for the development of obesity-related insulin resistance and type 2 diabetes mellitus (T2DM, which can be negatively regulated by Tregs. Our previous studies and those of others have shown that activation of γ-aminobutyric acid (GABA receptors inhibits inflammation in mice. However, whether GABA could modulate high fat diet (HFD-induced obesity, glucose intolerance and insulin resistance has not been explored. Here, we show that although oral treatment with GABA does not affect water and food consumption it inhibits the HFD-induced gain in body weights in C57BL/6 mice. Furthermore, oral treatment with GABA significantly reduced the concentrations of fasting blood glucose, and improved glucose tolerance and insulin sensitivity in the HFD-fed mice. More importantly, after the onset of obesity and T2DM, oral treatment with GABA inhibited the continual HFD-induced gain in body weights, reduced the concentrations of fasting blood glucose and improved glucose tolerance and insulin sensitivity in mice. In addition, oral treatment with GABA reduced the epididymal fat mass, adipocyte size, and the frequency of macrophage infiltrates in the adipose tissues of HFD-fed mice. Notably, oral treatment with GABA significantly increased the frequency of CD4(+Foxp3(+ Tregs in mice. Collectively, our data indicated that activation of peripheral GABA receptors inhibited the HFD-induced glucose intolerance, insulin resistance, and obesity by inhibiting obesity-related inflammation and up-regulating Treg responses in vivo. Given that GABA is safe for human consumption, activators of GABA receptors may be valuable for the prevention of obesity and intervention of T2DM in the clinic.

    Objective: To understand the current status of diagnosis and treatment of community-acquired pneumonia (CAP) among doctors in various hospitals across Shanghai, for the purpose of promoting the 2016 clinical practice guidelines for adult CAP of China. Methods: A questionnaire was designed to address the common questions in CAP management. The responses were collected via WeChat and the data were analyzed. Results: A total of 1 254 valid questionnaires were received, 46.1% from tertiary , 26.4% from secondary and 27.5% from primary care hospitals. Of these valid respondents, 31.4% were respiratory physicians and 68.6% from non-respiratory physicians. When diagnosing CAP, 78.1% of the doctors would use chest CT in more than 50% of the patients. Regarding the tools for evaluating the severity of CAP, 60.3% of the respondents would prefer CURB-65. "Respiratory failure requiring mechanical ventilation and septic shock" were the most common criteria for admission to ICU. Blood culture was not widely used in severe CAP regardless of the level of hospitals ( P >0.05). The results of this survey showed that the top 5 pathogenic microorganisms of CAP were Streptococcus pneumoniae, Mycoplasma pneumoniae, Klebsiella pneumoniae, Haemophilus influenza and Chlamydia pneumoniae. For non-severe CAP patients, all the doctors tended to select monotherapy. The most frequently used antimicrobial regimen for severe CAP was third- or fourth-generation cephalosporin monotherapy. As for combination therapy, the most frequently used regimen in tertiary hospitals was "carbapenem plus vancomycin" , while in primary and secondary hospitals it was "β-lactams plus macrolides" . More doctors from primary hospitals and non-respiratory medicine would consider "complete resolution of pulmonary opacity" as the indication to discontinue antimicrobial therapy or to discharge patients, and "prolonged high fever" , "large area consolidation" , "multiple lobe-segment involvement " as the indication for

    Patient expectations may be associated with outcomes of complementary and alternative medicine (CAM) treatments for chronic pain. However, a psychometrically sound measure of such expectations is needed. The purpose of this study was to develop and evaluate a questionnaire to assess individuals' expectations regarding outcomes of CAM treatments for chronic low back pain (CLBP), as well as a short form of the questionnaire. An 18-item draft questionnaire was developed through literature review, cognitive interviews with individuals with CLBP, CAM practitioners, and expert consultation. Two samples completed the questionnaire: (1) a community sample (n = 141) completed it via an online survey before or soon after starting a CAM treatment for CLBP, and (2) participants (n = 181) in randomized clinical trials evaluating CAM treatments for CLBP or fibromyalgia completed it prior to or shortly after starting treatment. Factor structure, internal consistency, test-retest reliability, and criterion validity were examined. Based on factor analyses, 10 items reflecting expectations (used to create a total score) and three items reflecting hopes (not scored) were selected for the questionnaire. The questionnaire had high internal consistency, moderate test-retest reliability, and moderate correlations with other measures of expectations. A three-item short form also had adequate reliability and validity. The Expectations for Complementary and Alternative Medicine Treatments (EXPECT) questionnaire can be used in research to assess individuals' expectations of treatments for chronic pain. It is recommended that the three hope questions are included (but not scored) to help respondents distinguish between hopes and expectations. The short form may be appropriate for clinical settings and when expectation measurement is not a primary focus.

    Full Text Available 2-DG triggers glucose deprivation without altering other nutrients or metabolic pathways and then activates autophagy via activation of AMPK and endoplasmic reticulum (ER stress. We investigated whether 2-DG reduced intracellular insulin increased by melatonin via autophagy/EDC3 in insulinoma INS-1E cells. p-AMPK and GRP78/BiP level were significantly increased by 2-DG in the presence/absence of melatonin, but IRE1α level was reduced in 2-DG treatment. Levels of p85α, p110, p-Akt (Ser473, Thr308, and p-mTOR (Ser2481 were also significantly reduced by 2-DG in the presence/absence of melatonin. Mn-SOD increased with 2-DG plus melatonin compared to groups treated with/without melatonin alone. Bcl-2 was decreased and Bax increased with 2-DG plus melatonin. LC3II level increased with 2-DG treatment in the presence/absence of melatonin. Intracellular insulin production increased in melatonin plus 2-DG but reduced in treatment with 2-DG with/without melatonin. EDC3 was increased by 2-DG in the presence/absence of melatonin. Rapamycin, an mTOR inhibitor, increased GRP78/BiP and EDC3 levels in a dose-dependent manner and subsequently resulted in a decrease in intracellular production of insulin. These results suggest that melatonin-mediated insulin synthesis during 2-DG treatment involves autophagy and EDC3 protein in rat insulinoma INS-1E cells and subsequently results in a decrease in intracellular production of insulin.

    We aimed to assess the use of metformin (MTF) in the prevention of gestational diabetes mellitus (GDM) in patients with pregestational insulin resistance (PIR). A double blind, multicenter, randomized trial was carried out in patients with a history of PIR and pregestational MTF treatment. Groups were allocated either to MTF 1700 mg/day or placebo. Patients were recruited between 12 +0 and 15 +6  gestational weeks, and treatment was extended until week 36. A multiple logistic regression analysis was applied to determine the relation between the use of metformin and the development of GDM. One hundred and forty one patients were randomized (68 patients in the MTF group and 73 in the placebo group). A total of 30 patients withdrew from the study during follow-up. Administration of MTF was not associated with a decrease in the incidence of GDM as compared to placebo (37.5% vs 25.4%, respectively; P = 0.2). Moreover, MTF administration was associated with a significant increase in drug intolerance as compared to placebo (14.3% vs 1.8%, respectively; P = 0.02). The use of MTF is not effective in prevention of GDM in populations with PIR. The use of MTF shows a significantly higher frequency of drug intolerance than placebo. © 2017 Japan Society of Obstetrics and Gynecology.

    ABSTRACT Objective To evaluate the psychometric properties of the seven theoretical models proposed in the literature for European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), when applied to a sample of Brazilian cancer patients. Methods Content and construct validity (factorial, convergent, discriminant) were estimated. Confirmatory factor analysis was performed. Convergent validity was analyzed using the average variance extracted. Discriminant validity was analyzed using correlational analysis. Internal consistency and composite reliability were used to assess the reliability of instrument. Results A total of 1,020 cancer patients participated. The mean age was 53.3±13.0 years, and 62% were female. All models showed adequate factorial validity for the study sample. Convergent and discriminant validities and the reliability were compromised in all of the models for all of the single items referring to symptoms, as well as for the “physical function” and “cognitive function” factors. Conclusion All theoretical models assessed in this study presented adequate factorial validity when applied to Brazilian cancer patients. The choice of the best model for use in research and/or clinical protocols should be centered on the purpose and underlying theory of each model. PMID:29694609

    This study demonstrates that aspartame consumption and insulin treatment in a juvenile diabetic rat model leads to increase in cytochrome P450 (CYP) 2E1 and CYP3A2 isozymes in brain. Diabetes mellitus was induced in postweaned 21-day-old Wistar male rat by streptozotocin. Animals were randomly assigned to one of the following groups: untreated control, diabetic (D), D-insulin, D-aspartame, or the D-insulin + aspartame-treated group. Brain and liver tissue samples were used to analyze the activity of CYP2E1 and CYP3A2 and protein levels. Our results indicate that combined treatment with insulin and aspartame in juvenile diabetic rats significantly induced CYP2E1 in the cerebrum and cerebellum without modifying it in the liver, while CYP3A2 protein activity increased both in the brain and in the liver. The induction of CYP2E1 in the brain could have important in situ toxicological effects, given that this CYP isoform is capable of bioactivating various toxic substances. Additionally, CYP3A2 induction in the liver and brain could be considered a decisive factor in the variation of drug response and toxicity. © The Author(s) 2014.

    The PaQ® insulin delivery system is a simple-to-use patch-on device that provides preset basal rates and bolus insulin on demand. In addition to feasibility of use, safety, and efficacy (reported elsewhere), this study analyzed the impact of PaQ on patient-reported outcomes, including barriers to insulin treatment, diabetes-related distress, and attitudes toward insulin therapy in patients with type 2 diabetes on a stable multiple daily injection (MDI) regimen. This single-center, open-label, single-arm study comprised three 2-week periods: baseline (MDI), transition from MDI to PaQ, and PaQ treatment. Validated questionnaires were administered during the baseline and PaQ treatment periods: Barriers to Insulin Treatment questionnaire (BIT), Insulin Treatment Appraisal Scale (ITAS), and Problem Areas in Diabetes scale (PAID). Eighteen patients (age 59 ± 5 years, diabetes duration 15 ± 7 years, 21% female, HbA1c 7.7 ± 0.7%) completed the questionnaires. There was a strong, significant effect of PaQ use in mean BIT total scores (difference [D] = -5.4 ± 0.7.7, P = .01, effect size [d] = 0.70). Patients perceived less stigmatization by insulin injection (D = -2.2 ± 6.2, P = .18, d = 0.35), increased positive outcome (D = 1.9 ± 6.6, P = .17, d = 0.29), and less fear of injections (1.3 ± 4.8, P = .55, d = 0.28). Mean change in ITAS scores after PaQ device use showed a nonsignificant improvement of 1.71 ± 5.63 but moderate effect size (d = 0.30, P = .14). No increase in PAID scores was seen. The results and moderate to large effects sizes suggest that PaQ device use has beneficial and clinically relevant effects to overcoming barriers to and negative appraisal of insulin treatment, without increasing other diabetes-related distress. © 2015 Diabetes Technology Society.

    Full Text Available Background. The aim of this study was to assess the subjective cure rate after the tension-free vaginal tape (TVT procedure in patients with stress (SUI and mixed (MUI urinary incontinence.Methods. This is a questionnaire based study done in 43 patients with SUI and 52 patients with MUI. In the assessement of the subjective cure rate the visual analogue scale and the symptom assessment index (SAI were used. Data were analyzed using nonparametric statistics.Results. The subjective cure rate assessed 19.6 months after TVT amounted to 89.3%. Urinary incontinence after TVT procedure was noted in 26 patients (27.4% and the majority of these women (73.1% were diagnosed with MUI. In patients with SUI and postoperative stable bladder a higher success rate was observed (96.7%. In 18.6% patients with SUI, de novo overactive bladder symptoms occurred. These patients estimated a significantly (p = 0.027 lower cure rate (81.9% after TVT procedure. In patients with MUI, the cure rate after TVT amounted to 85.6%. The subjective cure rate was lower (79.4% in case of persistent overactive bladder symptoms. However, it was significantly higher (97.5% in case of a postoperatively stable bladder (p = 0.016. In the group of MUI patients, the symptoms of overactive bladder disease resolved spontaneously in 17 patients (32.7% postoperatively. The patients were satisfied with TVT and 92.6% would recommend this procedure to others.Conclusions. The TVT procedure is a very effective method of treatment for stress as well as mixed urinary incontinence. The success rate of the procedure is high, however, it is influenced by bladder activity.

    Usage patterns and effectiveness of a longer-acting formulation of insulin glargine at a strength of 300 units per milliliter (Gla-300) have not been studied in real-world clinical practice. This study evaluated differences in dosing and clinical outcomes before and after Gla-300 treatment initiation in patients with type 2 diabetes starting or switching to treatment with Gla-300 to assess whether the benefits observed in clinical trials translate into real-world settings. This was a retrospective observational study using medical record data obtained by physician survey for patients starting treatment with insulin glargine at a strength of 100 units per milliliter (Gla-100) or Gla-300, or switching to treatment with Gla-300 from treatment with another basal insulin (BI). Differences in dosing and clinical outcomes before versus after treatment initiation or switching were examined by generalized linear mixed-effects models. Among insulin-naive patients starting BI treatment, no difference in the final titrated dose was observed in patients starting Gla-300 treatment versus those starting Gla-100 treatment [least-squares (LS) mean 0.43 units per kilogram vs 0.44 units per kilogram; P = 0.77]. Both groups had significant hemoglobin A 1c level reductions (LS mean 1.21 percentage points for Gla-300 and 1.12 percentage points for Gla-100 ; both P per kilogram before switch vs 0.58 units per kilogram after switch; P = 0.02). The mean hemoglobin A 1c level was significantly lower after switching than before switching (adjusted difference - 0.95 percentage points, 95% CI - 1.13 to - 0.78 percentage points ; P per patient-year were significantly lower (relative risk 0.17, 95% CI 0.11-0.26; P < 0.0001). Insulin-naive patients starting Gla-300 treatment had fewer hypoglycemic events, a similar hemoglobin A 1c level reduction, and no difference in insulin dose versus patients starting Gla-100 treatment.

    To investigate the combined effect of diet and orlistat, for 24 weeks, on anthropometric features, hormonal parameters, and indices of insulin resistance in obese women with polycystic ovary syndrome (PCOS) and in obese women without the syndrome. Prospective clinical study. Department of obstetrics and gynecology in a major university in Greece. Eighteen selected women with PCOS were matched for age and body mass index with 14 obese control women. Subjects were prescribed an energy-restricted diet, and orlistat (120 mg, 3 times per d) was administered to all subjects for 24 weeks. At baseline, week 12, and week 24, after an overnight fast, blood samples were collected, and serum levels of FSH, LH, PRL, T, Delta(4)A, DHEAS, 17 alpha-hydroxyprogesterone, sex hormone-binding globulin, glucose, and insulin were measured. Testosterone levels were significantly decreased with treatment in women with PCOS; this decrease was attributed to the first trimester, whereas T levels did not change during the second 12-week period. In women with PCOS, insulin levels and HOMA-IR values were decreased during the first 12 weeks, whereas no significant change was observed during the second trimester. Orlistat administration, combined with diet, for 24 weeks, resulted in significant weight loss and improvement of insulin resistance in obese women, with or without PCOS. Moreover, T levels were significantly decreased in women with PCOS. There appears to be a trend during the first 12-week period for greater improvement of metabolic and hormonal parameters in women with PCOS.

    To assess basal insulin persistence, associated factors, and economic outcomes for insulin-naïve people with type 2 diabetes mellitus (T2DM) in the US. People aged ≥18 years diagnosed with T2DM initiating basal insulin between April 2006 and March 2012 (index date), no prior insulin use, and continuous insurance coverage for 6 months before (baseline) and 24 months after index date (follow-up period) were selected using de-identified administrative claims data in the US. Based on whether there were ≥30 day gaps in basal insulin use in the first year post-index, patients were classified as continuers (no gap), interrupters (≥1 prescription after gap), and discontinuers (no prescription after gap). Factors associated with persistence - assessed using multinomial logistic regression model; annual healthcare resource use and costs during follow-up period - compared separately between continuers and interrupters, and continuers and discontinuers. Of the 19,110 people included in the sample (mean age: 59 years, ∼60% male), 20% continued to use basal insulin, 62% had ≥1 interruption, and 18% discontinued therapy in the year after initiation. Older age, multiple antihyperglycemic drug use, and injectable antihyperglycemic use during baseline were associated with significantly higher likelihoods of continuing basal insulin. Relative to interrupters and discontinuers, continuers had fewer emergency department visits, shorter hospital stays, and lower medical costs (continuers: $10,890, interrupters: $13,674, discontinuers: $13,021), but higher pharmacy costs (continuers: $7449, interrupters: $5239, discontinuers: $4857) in the first year post-index (p US. In addition, persistence patterns were assessed using administrative claims as opposed to actual medication-taking behavior and did not account for measures of glycemic control. Further research is needed to understand the reasons behind basal insulin persistence and the implications thereof, to help

    Full Text Available Abstract Background The Osteoporosis Patient Satisfaction Questionnaire (OPSAT-Q is a new measure of patient satisfaction with bisphosphonate treatment for osteoporosis. The objective of this study was to evaluate the psychometric characteristics of the OPSAT-Q. Methods The OPSAT-Q contains 16 items in four subscales: Convenience, Confidence with Daily Activities, Side Effects, and Overall Satisfaction. All four subscale scores and an overall composite satisfaction score (CSS can be computed. The OPSAT-Q, Osteoporosis Targeted Quality of Life (OPTQoL, and sociodemographic/clinical questionnaires, including 3 global items on convenience, functioning and side effects, were self-administered to women with osteoporosis or osteopenia recruited from four US clinics. Analyses included item and scale performance, internal consistency reliability, reproducibility, and construct validity. Reproducibility was measured using the intraclass correlation coefficient (ICC via a follow-up questionnaire completed by participants 2 weeks post baseline. Results 104 women with a mean age of 65.1 years participated. The majority were Caucasian (64.4%, living with someone (74%, and not currently employed (58.7%. 73% had osteoporosis and 27% had osteopenia. 80% were taking weekly bisphosphonates and 18% were taking daily medication (2% missing data. On a scale of 0–100, individual patient subscale scores ranged from 17 to 100 and CSS scores ranged from 44 to 100. All scores showed acceptable internal consistency reliability (Cronbach's alpha > 0.70 (range 0.72 to 0.89. Reproducibility ranged from 0.62 (Daily Activities to 0.79 (Side Effects for the subscales; reproducibility for the CSS was 0.81. Significant correlations were found between the OPSAT-Q subscales and conceptually similar global measures (p Conclusion The findings from this study confirm the validity and reliability of the OPSAT-Q and support the proposed composition of four subscales and a composite

    This study assessed whether myoinositol might be a first-line medical treatment for gestational diabetes mellitus (GDM). For 12 months, women with GDM not controlled by diet (n=32) were prospectively treated with myoinositol 1200mg and folic acid 400μg/day, while consecutive women (n=28) with insulin-requiring GDM treated during the previous year at our centre constituted the control group. Baseline characteristics and care were similar in both groups. Insulin was required in eight women (25%) in the myoinositol group who, compared with the 24 who did not need insulin, were older (37±5 vs. 32±5 years, respectively; P=0.018) and had a larger percentage of high self-monitored glucose values (45±8% vs. 32±14%; P<0.0001) during the week prior to the introduction of myoinositol treatment. All of the women had similar pregnancy outcomes regardless of their GDM management, although less labour induction was required in the myoinositol group (OR: 0.22 [0.07-0.65]), which had no side effects. This pilot study suggests that myoinositol may be a safe first-line medical treatment for uncontrolled GDM. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Since 2005, several glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have been approved to treat people with type 2 diabetes. These agents are considered for use at the same point in the treatment paradigm as basal insulins. A comprehensive comparison of these drug classes, therefore, can help inform treatment decisions. This systematic review and meta-analysis assessed the clinical efficacy and safety of GLP-1 RAs compared with basal insulins. MEDLINE, EMBASE, CENTRAL and PubMed databases were searched. Randomized clinical trials (RCTs) of ≥16 weeks' duration comparing GLP-1 RAs vs basal insulins in adults with type 2 diabetes inadequately controlled with oral antihyperglycemic drugs were included. Data on the change from baseline to 26 weeks (±10 weeks) of treatment in hemoglobin A1c (HbA1c) and weight, as well as the proportion of patients experiencing hypoglycaemia, were extracted. Fixed-effect pairwise meta-analyses were conducted where data were available from ≥2 studies. Fifteen RCTs were identified and 11 were meta-analysed. The once-weekly GLP-1 RAs, exenatide long acting release (LAR) and dulaglutide, led to greater, statistically significant mean HbA1c reductions vs basal insulins (exenatide: -0.31% [95% confidence interval -0.42, -0.19], dulaglutide: -0.39% [-0.49, -0.29]) whilst once-daily liraglutide and twice-daily exenatide did not (liraglutide: 0.06% [-0.06, 0.18], exenatide: 0.01% [-0.11, 0.13]). Mean weight reduction was seen with all GLP-1 RAs while mean weight gain was seen with basal insulins. Interpretation of the analysis of hypoglycaemia was limited by inconsistent definitions and reporting. Because of the limited number of available studies sensitivity analyses to explore heterogeneity could not be conducted. Although weight reduction is seen with all GLP-1 RA's, only the once-weekly agents, exenatide LAR and dulaglutide, demonstrate significant HbA1c reductions when compared to basal insulins. © 2016 The Authors.

    Increased insulin requirements in pregnancy can hinder attainment of glycemic control in diabetic patients. U-500 insulin is a concentrated form of regular insulin that can be a valuable tool in the treatment of patients with severe insulin resistance. A 24-year-old woman with pregestational diabetes mellitus experienced increasing insulin requirements during pregnancy, peaking at 650 units daily. The frequent, large-volume injections of standard-concentration insulin were poorly tolerated by the patient and resulted in nonadherence. She subsequently achieved glycemic control on thrice-daily U-500 insulin. Pregnancy exacerbates insulin resistance in diabetic patients, and these patients may require high doses of insulin. U-500 insulin is an effective alternative for patients with severe insulin resistance and should be considered for pregnant women with difficulty achieving glycemic control.

    In a randomized, multi-centre trial, the effect of an education programme (MEDIAS 2 ICT) involving intensive insulin treatment for people with type 2 diabetes was compared with an established education programme as an active comparator condition (ACC). We investigated whether MEDIAS 2 ICT was non-inferior to ACC in overall glycaemic control. Secondary outcomes were the diabetes-related distress, diabetes knowledge, quality of life, self-care behavior, lipids, blood pressure and weight. 186 subjects were randomized. After a six month follow-up the mean HbA1c decrease was 0.37% (from 8.2±1.1% to 7.8±1.5%) in the ACC and 0.63% (from 8.5±1.5% to 7.9±1.2%) in MEDIAS 2 ICT. The mean difference between both groups was -0.26% (95% CI -0.63 to -0.14) in favor of MEDIAS 2 ICT. This result was within the predefined limit for non-inferiority. Diabetes-related distress was significantly more reduced in MEDIAS 2 ICT (-3.4±7.1) than in ACC (0.4±9.0; p=0.31). MEDIAS 2 ICT is as effective in lowering HbA1c as previously established education programmes, but showed superiority in reducing diabetes-related distress. MEDIAS 2 ICT provides an alternative for education of people with type 2 diabetes treated by multiple injection therapy. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Diabetes mellitus is a growing in exponential proportions. If the current growth trend continues, it may result in every third adult in the United States having diabetes mellitus by 2050, and every 10 th adult worldwide. Type 2 diabetes mellitus (T2DM) confers a 2- to 3-fold increased risk of cardiovascular (CV) events compared with non-diabetic patients, and CV mortality is responsible for around 80% mortality in this population. Patients with T2DM can have other features of insulin resistance-metabolic syndrome like hypertension, lipid abnormalities, and obesity which are all associated with increased CV disease and stroke risk even in the absence of T2DM. The management of a T2DM calls for employing a holistic risk factor control approach. Metformin is the first line therapy for T2DM and has been shown to have cardiovascular beneficial effects. Intense debate regarding the risk of myocardial infarction with rosiglitazone led to regulatory agencies necessitating cardiovascular outcome trials with upcoming anti-diabetic medications. Glucagon like peptide-1 agonists and sodium glucose co-transporter-2 inhibitors have shown promising CV safety and additional CV benefit in recent clinical trials. These drugs have favorable effects on traditional CV risk factors. The findings from these studies further support that fact that CV risk factor control plays an important role in reducing morbidity and mortality in T2DM patients. This review article will discuss briefly the cardiovascular safety and benefits of the oral medications which are currently being used for T2DM and will then discuss in detail about the newer medications being investigated for the treatment of T2DM.

    Full Text Available The aim of the study was to compare the central corneal thickness (CCT, intraocular pressure (IOP, and tear insulin-like growth factor-1 (IGF-1 levels of 2 patients with acromegaly before and after the surgical treatment of the disease. CCTs, IOP levels, and tear IGF-1 values showed a decrease after the treatment in 2 patients. As we found higher CCT, IOP, and tear IGF-1 levels in the active phase of the disease in two acromegaly patients, detailed information about the activity of the disease may be important before the examination of these patients.

    Better control of blood sugar and reduction of diabetes complications through insulin therapy could convince people to choose this method. However, patients might refuse insulin therapy due to its painful injection, limitations in daily activities, and hypoglycemia. Thus, insulin therapy could have both positive and negative effects on patients' quality of life (QOL). Therefore, the aim of this study was to compare the QOL of insulin recipient and insulin refusal patients with type 2 diabetes. This study was a descriptive and comparative research conducted on 126 patients; 63 were insulin recipients and 63 had refused insulin therapy. Participants were under the care of the Endocrine and Metabolism Research Center of Isfahan, Iran. Data were gathered using the Diabetes Quality of Life (DQOL) questionnaire. In this tool, higher scores indicated lower QOL in patients. Data were analyzed using independent t-test, analysis of covariance, Mann-Whitney, Chi-square, and Pearson and Spearman's correlation. There was a significant difference (P refusal patients (mean = 1.74, SD = 0.41) in terms of mean QOL score. In addition, men and participants with higher educational levels reported a better QOL (P refusal patients had a better QOL. It seems that QOL is associated with the acceptance or refusal of insulin therapy. Therefore, enhancement of QOL could be related to all aspects of the disease, especially its treatment method and solving the therapeutic problems.

  19. The neuroprotective effects of intramuscular insulin-like growth factor-I treatment in brain ischemic rats.

    Directory of Open Access Journals (Sweden)

    Heng-Chih Chang

    Full Text Available Brain ischemia leads to muscle inactivity-induced atrophy and may exacerbate motor function deficits. Intramuscular insulin-like growth factor I (IGF-I injection has been shown to alleviate the brain ischemia-induced muscle atrophy and thus improve the motor function. Motor function is normally gauged by the integrity and coordination of the central nervous system and peripheral muscles. Whether brain ischemic regions are adaptively changed by the intramuscular IGF-I injection is not well understood. In this study, the effect of intramuscular IGF-I injection was examined on the central nervous system of brain ischemic rats. Rats were divided into 4 groups: sham control, brain ischemia control, brain ischemia with IGF-I treatment, and brain ischemia with IGF-I plus IGF-I receptor inhibitor treatment. Brain ischemia was induced by right middle cerebral artery occlusion. IGF-I and an IGF-1 receptor inhibitor were injected into the affected calf and anterior tibialis muscles of the treated rats for 4 times. There was an interval of 2 days between each injection. Motor function was examined and measured at the 24 hours and 7 days following a brain ischemia. The affected hind-limb muscles, sciatic nerve, lumbar spinal cord, and motor cortex were collected for examination after euthanizing the rats. IGF-I expression in the central nervous system and affected muscles were significantly decreased after brain ischemia. Intramuscular IGF-I injection increased the IGF-I expression in the affected muscles, sciatic nerve, lumbar spinal cord, and motor cortex. It also increased the p-Akt expression in the affected motor cortex. Furthermore, intramuscular IGF-I injection decreased the neuronal apoptosis and improved the motor function. However, co-administration of the IGF-I receptor inhibitor eliminated these effects. Intramuscular IGF-I injection after brain ischemia attenuated or reversed the decrease of IGF-I in both central and peripheral tissues, and

    We observed the curative effect of the 3C insulin system in combination with non-invasive ventilation in a patient with type 2 diabetes and obstructive sleep apnea syndrome (OSAS). The 3C insulin pump is a system of devices that closely monitors and effectively regulates blood glucose levels. Non-invasive ventilation has been shown to be an effective treatment for OSAS. A type 2 diabetes patient with concomitant OSAS was treated with a 3C insulin pump system for real-time continuous glucose monitoring and nocturnal non-invasive ventilation for OSAS. Treatment-induced diabetic remission with improved sleep and reduced hypoglycemic episodes was achieved. Therefore, the 3C insulin pump system, in combination with non-invasive ventilation, is an effective treatment for type 2 diabetes patients with concomitant OSAS. © 2017 The Authors.

    Rodrigo Oliveira Moreira

    Full Text Available CONTEXT: Insulin autoimmune syndrome (IAS, Hirata disease is a rare cause of hypoglycemia in Western countries. It is characterized by hypoglycemic episodes, elevated insulin levels, and positive insulin antibodies. Our objective is to report a case of IAS identified in South America. CASE REPORT: A 56-year-old Caucasian male patient started presenting neuroglycopenic symptoms during hospitalization due to severe trauma. Biochemical evaluation confirmed hypoglycemia and abnormally high levels of insulin. Conventional imaging examinations were negative for pancreatic tumor. Insulin antibodies were above the normal range. Clinical remission of the episodes was not achieved with verapamil and steroids. Thus, a subtotal pancreatectomy was performed due to the lack of response to conservative treatment and because immunosuppressants were contraindicated due to bacteremia. Histopathological examination revealed diffuse hypertrophy of beta cells. The patient continues to have high insulin levels but is almost free of hypoglycemic episodes.

    Full Text Available Objective. To investigate the relationship between insulin resistance and viral load decay in nondiabetic and noncirrhotic genotype 1 chronic HCV patients during peginterferon and ribavirin treatment and the possible influence of BMI and leptin as metabolic confounders. Methods. 75 consecutive noncirrhotic, nonobese, and nondiabetic patients with genotype 1 chronic hepatitis C treated with peginterferon alpha 2a plus ribavirin were evaluated. HOMA-IR, serum leptin, and BMI were measured in all patients at baseline and at weeks 12 and 48, whereas viral load was measured at the same time points and then 24 weeks after the end of treatment. Results. HOMA-IR was significantly associated with both BMI and leptin at baseline. During peginterferon plus ribavirin treatment, there was a significant reduction of HOMA-IR at weeks 12 and 48 from baseline (P=0.033 and 0.048, resp. in patients who achieved an early viral load decay (EVR, a trend not observed in patients who not achieved EVR. No variations during treatment were observed regarding BMI and leptin irrespective of EVR. Conclusion. The early reduction of HOMA-IR but not of BMI and leptin during antiviral treatment in noncirrhotic, chronic hepatitis C genotype 1 patients who achieved EVR suggests a viral genesis of insulin resistance in patients with nonmetabolic phenotype.

The objective of this study was to evaluate the validity of the uro-gynaecological questionnaire (UGQ), a new instrument for patient self-assessment of urological-, genital-, menopausal-, and pain symptomatology in gynaecological cancer patients. Material and methods: The UGQ was developed after literature review, patient- and expert interviews and pilot testing. From February 1992 to October 1992, 88 gynaecological cancer patients were invited to participate in a validation study after the initiation of their primary radiotherapy or chemotherapy. The method of validation investigated whether patients and researchers interpreted the items of the questionnaire in the same way. The patient's written response before interview was compared with an observer rating of the patient's open-ended audio-taped responses to the same questionnaire, administered as an interview. Qualitative recordings by the observer were made to describe potential misinterpretations. Results: The agreement between the patient's and the observer's ratings was high: the median overall agreement was 0.91 (range 0.71-1.00) and the median kappa was 0.88 (range 0.45-1.00). The quantitative and the qualitative results identified a few minor validity problems; especially, the issue of selective reporting, i.e. some patients only reporting those symptoms they considered relevant for the study, which may lead to systematic errors. Conclusions: The results strongly suggest that patients interpret the UGQ items as intended, i.e. they are valid. The UGQ is recommended for patient self-assessment of uro-gynaecological morbidity in gynaecological cancer patients

    Parkinsonia aculeata L. (Caesalpiniaceae) is a traditional ethnomedicine and has been used for the empiric treatment of hyperglycemia, without scientific background. Mechanistic analyses at molecular level from the antioxidant mechanism observed by P. aculeata are required. Herein the effects of the treatment by hydroethanolic extract partitioned with ethyl acetate of P. aculeata aerial parts (HEPa/EtOAc) in mice fed a high-fat diet that share many obesity phenotypes with humans were evaluated. The animals were treated orally with HEPa/EtOAc (125 and 250 mg/kg/day) and pioglitazone (5 mg/kg/day), for 16 days. After the treatment, HEPa/EtOAc reduced fasting serum glucose and insulin levels, as well as homeostasis model assessment for insulin resistance. In addition, an improvement in glucose intolerance was also observed. Indeed, a reduction in the circulating levels of TNF-α and IL-6 was also observed. Furthermore, at molecular level, it was demonstrated that the HEPa/EtOAc treatment was able to improve these physiological parameters, through the activation of peroxisome proliferator-activated receptor γ (PPARγ) per si, as well as the enhancement of antioxidant mechanism by an increase in PPARγ/Cu(2+), Zn(2+)-superoxide dismutase (CuZn-SOD) axis expression in liver and adipose tissue. In sum, P. aculeata is effective to improve insulin resistance in a mouse model of obesity and this effect seems to involve the antioxidant and anti-inflammatory mechanisms through the increase in PPARγ/CuZn-SOD axis expression.

    The constitutive androstane receptor (CAR) has been reported to decrease insulin resistance even during pregnancy, while exposure to a high-fat diet (HFD) in utero in mice can induce a type 2 diabetes phenotype that can be transmitted to the progeny. Therefore, we examined whether treatment with a CAR ligand during pregnancy could prevent hypertension, insulin resistance, and hyperlipidemia in the offspring from HFD-induced obese pregnant mice (OH mice). We employed four groups of offspring from HFD-fed and control diet-fed pregnant mice with or without treatment with a CAR ligand. Treatment with a CAR ligand during pregnancy improved glucose tolerance and the levels of triglyceride and adipocytokine and restored the changes induced by HFD with amelioration of hypertension in the adult OH mice. This treatment also increased adiponectin mRNA expression, suppressed leptin expression in adipose tissues of OH mice, and abolished the effect of HFD on the epigenetic modifications of the genes encoding adiponectin and leptin in the offspring during immaturity and adulthood. Our data suggest that CAR might be a potential therapeutic target to prevent metabolic syndrome in adulthood of offspring exposed to an HFD in utero.

    Insulin resistance (IR) plays a central role in the development of several metabolic diseases, which leads to increased morbidity and mortality rates, in addition to soaring health-care costs. Deep sea water (DSW) and fucoidans (FPS) have drawn much attention in recent years because of their potential medical and pharmaceutical applications. This study investigated the effects and mechanisms of combination treatment of DSW and FPS in improving IR in HepG2 hepatocytes induced by a high glucose concentration. The results elucidated that co-treatment with DSW and FPS could synergistically repress hepatic glucose production and increase the glycogen level in IR-HepG2 cells. In addition, they stimulated the phosphorylation levels of the components of the insulin signaling pathway, including tyrosine phosphorylation of IRS-1, and serine phosphorylation of Akt and GSK-3β. Furthermore, they increased the phosphorylation of AMPK and ACC, which in turn decreased the intracellular triglyceride level. Taken together, these results suggested that co-treatment with DSW and FPS had a greater improving effect than DSW or FPS alone on IR. They might attenuate IR by targeting Akt/GSK-3β and AMPK pathways. These results may have some implications in the treatment of metabolic diseases. PMID:29393871

    Full Text Available Objective: To investigate the influence of oral antidiabetic drug and combined with basal insulin treatment on diabetic control and micro-inflammatory state in type 2 diabetes mellitus patients. Methods: From May 2014 to June 2015, 128 cases of Type 2 diabetes mellitus were recruited and divided randomly into two groups as observation group and control group. The observation group was given metformin (Glucophage, 0.25 tid plus basal insulin (glargine treatment, while the control group was given metformin (Glucophage, initial dose of 0.25 tid; the largest total dose of 2 g plus other non-euglycemic OADs necessarily for 6 months to adjust dose and control blood glucose at target. The diabetic control indexes, islet function and micro-inflammatory factors were detected and analyzed. Results: After 6 months of medication, the observation group showed significantly lower level of FPG, and HbA1cthan the control group. While AUCc-p, HOMA-β and HOMA-IR of the observation group showed significant difference compared to that of the control group after treatment. Also the microinflammatory indexes including hs-CRP, IGF-1, IL-6 and TNF-α of the observation group after treatment were significantly lower than the control group . Conclusions: Type 2 diabetes given metformin plus glargine not only could control and steady blood glucose, but also significant decrease the micro-inflammation state.

    To determine the effects of dipeptidyl peptidase-4 (DPP-4) inhibition on glucagon dynamics in patients with insulin-treated type 2 diabetes (T2D). The study was a single-centre, double-blind, randomized, placebo controlled crossover study in patients with T2D, mean age 59 ± 6 (s.d.) years and mean haemoglobin A1c 7.7 ± 0.8%, treated with exogenous insulin with or without oral antihyperglycaemic agents. Patients received vildagliptin (50 mg BID) or placebo as add-on to insulin for 4 weeks in random order with a 4-week washout in-between. On day 28 of the respective treatment, patients were served a standard meal (500 kcal) followed by a hyperinsulinaemic hypoglycaemic clamp (target 2.5 mmol/l) and a subsequent food re-challenge (700 kcal). The completers population (n = 29) was analysed. Glucose levels were lower with vildagliptin than with placebo during the meal [areas under the curve (AUC) 1.23 ± 0.07 vs. 1.46 ± 0.05 mol/l min, P vildagliptin (AUC 1.98 ± 0.15 vs. 2.15 ± 0.17 nmol/l min, P = 0.016). In contrast, the glucagon counter-regulation to the insulin-induced hypoglycaemia was sustained by vildagliptin (6.05 ± 1.20 pmol/l during vildagliptin vs.6.94 ± 1.09 pmol/l during placebo, NS). During the food re-challenge after hypoglycaemia, glucagon levels were, again, significantly lower after vildagliptin (AUC 1.30 ± 0.11 vs. 1.52 ± 0.12 nmol/l min, P vildagliptin compared to placebo during meal, hypoglycaemia and food re-challenge. Vildagliptin action to block GLP-1 and GIP inactivation by DPP-4 improves glucagon dynamics during hypoglycaemia, hyperglycaemia and food re-challenge. © 2014 John Wiley & Sons Ltd.

    Abstract Background and aims: Intensification of basal insulin-only therapy in type 2 diabetes is often achieved through addition of bolus insulin 3-times daily. The FullSTEP trial demonstrated that stepwise addition (SWA) of bolus insulin aspart was non-inferior to full basal-bolus (FBB) therapy and reduced the rate of hypoglycemia. Here the cost-effectiveness and budget impact of SWA is evaluated. Cost-effectiveness and budget impact models were developed to assess the cost and quality-of-life (QoL) implications of intensification using SWA compared with FBB in the US setting. At assessment, SWA patients added one bolus dose to their current regimen if the HbA1c target was not met. SWA patients reaching three bolus doses used FBB event rates. Outcomes were evaluated at trial end and projected annually up to 5 years. Models captured hypoglycemic events, the proportion meeting HbA1c target, and self-measured blood glucose. Event rates and QoL utilities were taken from trial data and published literature. Costs were evaluated from a healthcare-payer perspective, reported in 2013 USD, and discounted (like clinical outcomes) at 3.5% annually. This analysis applies to patients with HbA1c 7.0-9.0% and body mass index Budget impact analysis estimated that, by moving from FBB to SWA, a health plan with 77,000 patients with type 2 diabetes, of whom 7.8% annually intensified to basal-bolus therapy, would save USD 1304 per intensifying patient over the trial period. SWA of bolus insulin should be considered a beneficial and cost-saving alternative to FBB therapy for the intensification of treatment in type 2 diabetes.

    The aim of this study was to assess carbohydrate (CHO)-to-insulin ratio (CHO/IR) values in pregnant women with type 1 diabetes and to describe differences in CHO/IR across each week of pregnancy. This was a multicenter, retrospective, observational study (2006-2012) of 101 white pregnant women with a mean age of 32 (range, 18-43) years who had type 1 diabetes and were under continuous subcutaneous insulin infusion (CSII) therapy. These patients had the following characteristics: type 1 diabetes duration was 1 year (range, 1-31 years), the pregestational glycosylated hemoglobin level was 6.9% (range, 6.8-12.1%), the median weight gain during pregnancy was 14 kg (-3; 25 kg), with delivery at 37 weeks (range, 30-40 weeks), and the child had a birth weight of 3.530 kg (range, 1.480-5.250 kg). The CHO/IR was measured by dividing the CHO (in g) of each meal by insulin unit injected to acquire and maintain the following glycemic targets: fasting insulin and 300/total daily doses of insulin. Education and management before and during pregnancy were in agreement with Italian Association of Dietitians, Association of Medical Diabetologists, and Italian Society of Diabetology recommendations. Data were analyzed using SPSS software (version 20.0; SPSS, Inc., Chicago, IL). The CHO/IR decreased on average from 9.6 (5-18) to 5.4 (2.3-8) at breakfast, from 10 (3.5-16) to 8.4 (3.0-17.8) at lunch, and from 12.5 (8-20) to 6.1 (4.2-12) at dinner. The CHO/IR calculated using the "500 rule" decreased from 14.3 (10-20.3) to 8.6 (4.1-15.9). Using the "300 rule," the ratios decreased from 8.5 (6-12.1) to 5.2 (2.4-9.5). The bivariate correlation between the values calculated more appropriate values using the "300 rule" for breakfast and the "500 rule" for lunch and dinner across all weeks of pregnancy. CHO/IR reduction in pregnancy is likely due to an increase in insulin resistance.

    Full Text Available Obesity is a major public health problem that is highly associated with insulin resistance and type 2 diabetes, two conditions associated with circadian disruption. To date, dieting is one of the only interventions that result in substantial weight loss, but restricting caloric intake is difficult to maintain long-term. The use of artificial sweeteners, particularly in individuals that consume sugar sweetened beverages (energy drinks, soda, can reduce caloric intake and possibly facilitate weight loss. The purpose of the present study was to examine the effects of the artificial sweetener, rebaudioside A (Reb-A, on circadian rhythms, in vivo insulin action, and the susceptibility to diet-induced obesity. Six month old male C57BL/6 mice were assigned to a control or Reb-A (0.1% Reb-A supplemented drinking water group for six months. Circadian wheel running rhythms, body weight, caloric intake, insulin action, and susceptibility to diet-induced obesity were assessed. Time of peak physical activity under a 12:12 light-dark (LD cycle, mean activity levels, and circadian period in constant dark were not significantly different in mice that consumed Reb-A supplemented water compared to normal drinking water, indicating that circadian rhythms and biological clock function were unaltered. Although wheel running significantly reduced body weight in both Reb-A and control mice (P = 0.0001, consuming Reb-A supplemented water did not alter the changes in body weight following wheel running (P = 0.916. In vivo insulin action, as assessed by glucose, insulin, and pyruvate tolerance tests, was not different between mice that consumed Reb-A treated water compared to normal drinking water. Finally, Reb-A does not appear to change the susceptibility to diet-induced obesity as both groups of mice gained similar amounts of body weight when placed on a high fat diet. Our results indicate that consuming Reb-A supplemented water does not promote circadian disruption

    Pancreatic islet cell transplantation is an effective approach to treat type 1 diabetes, however the shortage of cadaveric donors and limitations due to rejection require alternative solutions. Multipotent cells derived from the uterine endometrium have the ability to differentiate into mesodermal and ectodermal cellular lineages, suggesting the existence of mesenchymal stem cells in this tissue. We differentiated human endometrial stromal stem cells (ESSC) into insulin secreting cells using ...

    Full Text Available Background: The A 1 chieve, a multicentric (28 countries, 24-week, non-interventional study evaluated the safety and effectiveness of insulin detemir, biphasic insulin aspart and insulin aspart in people with T2DM (n = 66,726 in routine clinical care across four continents. Materials and Methods: Data was collected at baseline, at 12 weeks and at 24 weeks. This short communication presents the results for patients enrolled from Casablanca, Morocco. Results: A total of 495 patients were enrolled in the study. Four different insulin analogue regimens were used in the study. Study patients had started on or were switched to biphasic insulin aspart (n = 231, insulin detemir (n = 151, insulin aspart (n = 19, basal insulin plus insulin aspart (n = 53 and other insulin combinations (n = 41. At baseline glycaemic control was poor for both insulin naïve (mean HbA 1 c: 10.2% and insulin user (mean HbA 1 c: 9.4% groups. After 24 weeks of treatment, both groups showed improvement in HbA 1 c (insulin naïve: −2.3%, insulin users: −1.8%. Major hypoglycaemia was observed in the insulin naïve group after 24 weeks. SADRs were reported in 1.2% of insulin naïve and 2.1% of insulin user groups. Conclusion: Starting or switching to insulin analogues was associated with improvement in glycaemic control with a low rate of hypoglycaemia.

    Full Text Available Corticosteroids (CS effects on insulin resistance related genes in rat skeletal muscle were studied. In our acute study, adrenalectomized (ADX rats were given single doses of 50 mg/kg methylprednisolone (MPL intravenously. In our chronic study, ADX rats were implanted with Alzet mini-pumps giving zero-order release rates of 0.3 mg/kg/h MPL and sacrificed at various times up to 7 days. Total RNA was extracted from gastrocnemius muscles and hybridized to Affymetrix GeneChips. Data mining and literature searches identified 6 insulin resistance related genes which exhibited complex regulatory pathways. Insulin receptor substrate-1 (IRS-1, uncoupling protein 3 (UCP3, pyruvate dehydrogenase kinase isoenzyme 4 (PDK4, fatty acid translocase (FAT and glycerol-3-phosphate acyltransferase (GPAT dynamic profiles were modeled with mutual effects by calculated nuclear drug-receptor complex (DR(N and transcription factors. The oscillatory feature of endothelin-1 (ET-1 expression was depicted by a negative feedback loop. These integrated models provide test- able quantitative hypotheses for these regulatory cascades.

Our aim was to study the change in QoL of patients with severe persistent bronchial asthma (BA during the treatment with genetically engineered biological preparation (GIBP omalizumab in addition to daily background therapy. Methods. The QoL assessment was conducted using the Health Utilities Index Mark 3 and Mark 2 (HUI3, HUI2 questionnaires at two points (1st point and 2nd point — in 6 months in 47 children with severe BA at the age of 13 (7; 17 years, 72% of them are boys. At the same points, QoL was evaluated using the PAQLQ (S specialized pediatric questionnaire (Standardized Pediatric Asthma Quality of Life Questionnaire. Results. Depending on the duration of omalizumab therapy, all children were divided into 5 groups: 1st group — children who did not receive treatment with monoclonal antibodies at the 1st point; in 2, 3, 4, 5-th groups, the QoL assessment was performed on GIBP treatment for different time. In children of the 1st group whose QoL was evaluated before starting GIBP therapy and in 6 months, a statistically significant change in scores on the Health Utilities Index questionnaire was noted: the multi-attribute indices HUI2 and HUI3 improved, respectively, by 21.3 and 10.71% (p = 0.041 and 0.086. According to the HUI2 classification system, a significant improvement in the emotion attribute was revealed, which positively correlated with the overall indicator and the emotion indicator of the PAQLQ (S questionnaire. In the remaining groups, the indicators of the Health Utilities Index questionnaire did not change significantly. Conclusion. The study results showed that the dynamics of the quality of life in children with severe persistent BA is an important additional criterion in a comprehensive assessment of the efficacy of targeted bioengineering therapy.

    Idiopathic short stature (ISS) constitutes a heterogeneous group of short stature which is not associated with an endocrine or other identifiable cause. Some ISS patients may have varying degrees of insulin-like growth factor-1 (IGF-1) deficiency. Recombinant growth hormone (rGH) treatment has been used by some authors with variable results. Reports on long-term rGH treatment are limited. In this study, 21 slowly growing, non-GH-deficient ISS children who received rGH treatment for 3.62±0.92 years were evaluated at the end of a 5.42±1.67-year follow-up period. The study group included patients with low IGF-1 levels who also responded well to an IGF generation test. The patients were divided into two groups as good responders [height increment >1 standard deviation (SD)] and poor responders (height increment deficit and almost 40% of patients may reach their target height.

    In balance system assessment there is no single set of tests applicable for all patients. A comprehensive medical history plays a main role in balance assessment. Patients often describe the same disorders in different ways. The aim of our work was to analyze effectiveness of betahistine hydrochloride (Betaserc) treatment on vertigo, nausea, vomiting, tinnitus and progressive hearing loss basing on the medical assessment (interview) performed by doctors and patient's personal questionnaires as well as to collect and accumulate data about balance system disorders. We prepared questionnaires for both doctors and patients. The doctor's questionnaire was divided into three sections. In the first section we included questions about direct cause of visit at the doctor's office. Questions were covering problems regarding balance system disorders (difficulty to keep erect position), vertigo, tinnitus, hearing impairment and other problems. The second section of the questionnaire included assessment of treatment effectiveness through the first 14 days and on the 28th day (a control visit). A third section of the questionnaire was focused on estimation of intensity of balance system disturbances. Patient's questionnaire included everyday self observations of intensity of disturbances within the 14 days observation period. We analyzed data of 980 patients, of the age between 16 and 96 years (mean age--54.1). There were 57.8% females and 42.2% males. From the group of 980 patients we separated a group of patients under 40 and over 60 years of age for additional analysis. Having analyzed doctors questionnaires we noted that the most frequent cause of patients' visits were: vertigo--in 770 people (78.57%), tinnitus--in 708 people (72.24%), disturbance of balance system--in 612 people (62.45%), hearing loss--in 607 people (61.94%) and other problems--in 72 people (7.35%). Patients over 60 years of age described vertigo as rolling and falling (38.92%). Patients under 40 years of

    Topical treatment of mild to moderate psoriasis is first-line treatment and exhibits varying degrees of success across patient groups. Key factors influencing treatment success are physician topical treatment choice (high efficacy, low adverse events) and strict patient adherence. Currently, no formalized, international consensus guidelines exist to direct optimal topical treatment, although many countries have national guidelines. To describe and analyse cross-regional variations in the use and access of psoriasis topical therapies. The study was conducted as an observational cross-sectional study. A survey was distributed to dermatologists from the International Psoriasis Council (IPC) to assess topical therapy accessibility in 26 countries and to understand how body surface area (BSA) categories guide clinical decisions on topical use. Variation in the availability of tars, topical retinoids, dithranol and balneotherapy was reported. The vast majority of respondents (100% and 88.4%) used topical therapy as first-line monotherapy in situations with BSA 10%, the number of respondents who prescribe topical therapy decreased considerably. In addition, combination therapy of a topical drug and a systemic drug was frequently reported when BSA measured >10%. This physician survey provides new evidence on topical access and the influence of disease severity on topical usage in an effort to improve treatment strategies on a global level. © 2017 European Academy of Dermatology and Venereology.

    Dual-release hydrocortisone (DR-HC) provides physiological cortisol exposure, leading to an improvement of anthropometric and metabolic parameters. The aim of the study was to evaluate the effects of DR-HC on insulin secretion and sensitivity and cardiometabolic risk, indirectly expressed by the visceral adiposity index (VAI). Retrospective analysis of 49 patients, 13 with primary and 36 with secondary adrenal insufficiency (AI), respectively, on conventional glucocorticoid treatment at baseline and switched to DR-HC for 36 months. Overall, 24 patients had AI-pre-diabetes (impaired fasting glucose, impaired glucose tolerance and the combination), and 25 had AI-normal glucose tolerance (NGT). Clinical and metabolic parameters, including VAI, insulin secretion and sensitivity indexes (fasting insulinaemia, AUC 2 h insulinaemia , oral disposition index [Dio] and ISI-Matsuda), were evaluated. In patients with AI-NGT and AI-prediabetes, a significant decrease in BMI (P = .017 and P 36 and P = .043) was, respectively, observed. In addition, in prediabetic patients, only we found a significant decrease in insulinaemia (P = .014), AUC 2 h insulinaemia (P = .038) and VAI (P = .001), in concomitance with a significant increase in DIo (P = .041) and ISI-Matsuda (P = .038). Long-term DR-HC therapy is associated with an improvement in insulin secretion and sensitivity in patients with prediabetes. However, all patients appear to benefit from the treatment in terms of improvement of metabolic and anthropometric parameters. Larger studies are required to confirm our preliminary data. © 2018 John Wiley & Sons Ltd.

  7. Insulin resistance, insulin sensitization and inflammation in polycystic ovarian syndrome

    Full Text Available It is estimated that 5-10% of women of reproductive age have polycystic ovarian syndrome (PCOS. While insulin resistance is not part of the diagnostic criteria for PCOS, its importance in the pathogenesis of PCOS cannot be denied. PCOS is associated with insulin resistance independent of total or fat-free body mass. Post-receptor defects in the action of insulin have been described in PCOS which are similar to those found in obesity and type 2 diabetes. Treatment with insulin sensitizers, metformin and thiazolidinediones, improve both metabolic and hormonal patterns and also improve ovulation in PCOS. Recent studies have shown that PCOS women have higher circulating levels of inflammatory mediators like C-reactive protein, tumour necrosis factor- , tissue plasminogen activator and plasminogen activator inhibitor-1 (PAI-1 . It is possible that the beneficial effect of insulin sensitizers in PCOS may be partly due to a decrease in inflammation.

    A subcutaneous (SC) formulation of rituximab (MabThera ® /Rituxan ® ) has been developed that could reduce administration time and improve patient satisfaction with treatment. The Rituximab Administration Satisfaction Questionnaire (RASQ) was created to assess patients' perceptions and satisfaction with rituximab SC (RASQ-SC) or rituximab intravenous (RASQ-IV). We assessed the content validity and psychometric properties of RASQ in patients with non-Hodgkin lymphoma. Face and content validity of RASQ-SC and RASQ-IV were qualitatively assessed using 60-minute combined concept elicitation and cognitive debriefing interviews. Psychometric validation of RASQ (item performance and reliability) was assessed quantitatively against the established Cancer Therapy Satisfaction Questionnaire (CTSQ), using questionnaire data from the PrefMab (NCT01724021) and MabCute (NCT01461928) clinical studies. RASQ-IV demonstrated excellent coverage of concepts relevant to patients' (n=10) own treatment experiences and no new concepts were identified. Patients' expectations of rituximab SC were conceptually consistent with items included in the RASQ-SC, suggesting that the tool is also conceptually adequate. In 1,051 patients from PrefMab and MabCute, correlations with domains such as "RASQ: Physical Impacts" and "CTSQ: Feelings About Side Effects", "RASQ: Physical Impacts" and "CTSQ: Satisfaction With Therapy", and "RASQ: Satisfaction" and "CTSQ: Satisfaction With Therapy", achieved moderate-to-high correlations (>0.4) for convergent domains and <0.3 for divergent domains. This study supports the qualitative face and content validity and psychometric validity of RASQ-IV and RASQ-SC. Minor revisions were made to the questionnaires to enhance clarity and aid consistent reporting.

    Investigation of patients' subjective perspective regarding the effectiveness - as opposed to efficacy - of antipsychotic medication has been hampered by a relative shortage of self-report measures of global clinical outcome. This paper presents data supporting the feasibility, inter-item consistency, and construct validity of the Patient Assessment Questionnaire (PAQ)-a self-report measure of psychiatric symptoms, medication side effects and general wellbeing, ultimately intended to assess effectiveness of interventions for schizophrenia-spectrum patients. The original 53-item instrument was developed by a multidisciplinary team which utilized brainstorming sessions for item generation and content analysis, patient focus groups, and expert panel reviews. This instrument and additional validation measures were administered, via Audio Computer-Assisted Self-Interviewing (ACASI), to 300 stable, medicated outpatients diagnosed with schizophrenia or schizoaffective disorder. Item elimination was based on psychometric properties and Item-Response Theory information functions and characteristic curves. Exploratory factor analysis of the resulting 40-item scale yielded a five factor solution. The five subscales (General Distress, Side Effects, Psychotic Symptoms, Cognitive Symptoms, Sleep) showed robust convergent (β's=0.34-0.75, average β=0.49) and discriminant validity. The PAQ demonstrates feasibility, reliability, and construct validity as a self-report measure of multiple domains pertinent to effectiveness. Future research needs to establish the PAQ's sensitivity to change. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    In the context of quality assurance, increasing demands are placed on the whole radiotherapy treatment process. The patients directly concerned generally do not realize most aspects of the quality assurance program (e.g., additional safety checks) during their daily therapy. It was the aim of this study to systematically ask patients about potential improvements during the course of radiotherapy treatment from their own perspective. In the defined time span (1 month), 624 radiotherapy patients (600 questionnaires were returned, 96.2%) were interviewed using a questionnaire newly developed to inquire about several aspects of their treatment. Furthermore, they were asked for their specific needs and suggestions for improvements that could be made during the course of radiotherapy treatment. Overall, the patients were satisfied with the course of their radiotherapy treatment and with patient care. As an example, about 90% agreed with the statement: ''My first contact with the radiation oncology unit proceeded with kindness and competence so that I was given the impression that I will be well cared for in this clinic.'' Considering the organization of the course of radiotherapy, a large majority of patients attached great value to set appointments for the therapy fractions. A main point of criticism was waiting times or delays caused by servicing or machine failures. Small, low cost improvements as music in the therapy room were considered as important as expensive measures (e.g., daylight in the therapy room). The patients emphasized the importance of staff friendliness. The situation of radiotherapy patients was, in general, satisfactory. Future improvements can be mainly expected from smooth organisation of both planning and treatment which can be achieved by electronic scheduling systems. Many results of the survey could be easily implemented in daily practice. In matters of organization radiation oncology with its complex procedures can be used

The questionnaire for patients with elevated blood pressure (BP developed by S. N. Gerasimov et al. (2015 was used. The questionnaire included 16 questions organized in the following panels: awareness of hypertension and risk factors, BP self-monitoring, conducted treatment, compliance to therapy, referrals to medical care. Results. 90% of the interviewed patients have known previously about BP elevation; 90% of respondents have had a tonometer; 84% of hypertensives measured BP no rare then once a week, and 54% did it daily; 88% of enrollers regularly take antihypertensive drugs. Only 36% of patients could be classified as compliant to therapy according the Morisky — Green scale (had 4 points. 92% of respondents have received one or more advice on lifestyle modification: 82% — advice on eating, 66% — advice on weight reduction, 55% — advice on physical activity, 28% — advice on smoking cessation, 26% — advice on alcohol consumption. 62.7% of patients were interested in organization of special follow-up program. Conclusion. High frequency of BP self-measurement was identified together with low compliance of patients to antihypertensive therapy, good knowledge on non-pharmacologic treatment interventions.

  13. Short-term vitamin E treatment impairs reactive oxygen species signaling required for adipose tissue expansion, resulting in fatty liver and insulin resistance in obese mice.

    Full Text Available The use of antioxidant therapy in the treatment of oxidative stress-related diseases such as cardiovascular disease, diabetes or obesity remains controversial. Our aim is to demonstrate that antioxidant supplementation may promote negative effects if used before the establishment of oxidative stress due to a reduced ROS generation under physiological levels, in a mice model of obesity.C57BL/6J mice were fed with a high-fat diet for 14 weeks, with (OE group or without (O group vitamin E supplementation.O mice developed a mild degree of obesity, which was not enough to induce metabolic alterations or oxidative stress. These animals exhibited a healthy expansion of retroperitoneal white adipose tissue (rpWAT and the liver showed no signs of lipotoxicity. Interestingly, despite achieving a similar body weight, OE mice were insulin resistant. In the rpWAT they presented a reduced generation of ROS, even below physiological levels (C: 1651.0 ± 212.0; O: 3113 ± 284.7; OE: 917.6 ±104.4 RFU/mg protein. C vs OE p< 0.01. ROS decay may impair their action as second messengers, which could account for the reduced adipocyte differentiation, lipid transport and adipogenesis compared to the O group. Together, these processes limited the expansion of this fat pad and as a consequence, lipid flux shifted towards the liver, causing steatosis and hepatomegaly, which may contribute to the marked insulin resistance.This study provides in vivo evidence for the role of ROS as second messengers in adipogenesis, lipid metabolism and insulin signaling. Reducing ROS generation below physiological levels when the oxidative process has not yet been established may be the cause of the controversial results obtained by antioxidant therapy.

    The aim of the present study was to conduct a cross-cultural adaptation (with translation into Brazilian Portuguese) and validation of the European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire-Bone Metastases-22 (EORTC QLQ-BM22). Ninety-five bone metastasis patients (31 men and 64 women, mean age 58.36±8.90 years) took part in the investigation. The translation guide of the EORTC was used to translate from English into Brazilian Portuguese and adapt the instrument culturally. The reliability and the face, content and construct validities were tested. Internal consistency was estimated using Cronbach's alpha for the total score, pain and functional subscales of the EORTC QLQ-BM22 (0.93, 0.86, 0.90). Reliability was analyzed by Pearson's correlation and intraclass correlation coefficients (ICCs). The correlations were higher than the recommended value of 0.75, which indicated good test-retest reliability. Construct validity was demonstrated by correlation with the questionnaire medical outcome study questionnaire 36-Item Short Form Survey (SF-36). It showed significant correlation between the fields of QLQ-BM22 and the SF-36 (P≤0.001). The EORTC QLQ-BM22 was translated into Brazilian Portuguese, was culturally adapted and was proven to be reliable, with face, content and construct validity.

    OBJECTIVE: This study compared the ability of glucagon to restore plasma glucose (PG) after mild hypoglycemia in patients with type 1 diabetes on an isocaloric high-carbohydrate diet (HCD) versus a low-carbohydrate diet (LCD). RESEARCH DESIGN AND METHODS: Ten patients with insulin pump-treated type...... 1 diabetes randomly completed 1 week of the HCD (≥250 g/day) and 1 week of the LCD (≤50 g/day). After each week, mild hypoglycemia was induced by a subcutaneous insulin bolus in the fasting state. When PG reached 3.9 mmol/L, 100 µg glucagon was given subcutaneously, followed by 500 µg glucagon 2 h...... later. RESULTS: Compared with the HCD, the LCD resulted in lower incremental rises in PG after the first (mean ± SEM: 1.3 ± 0.3 vs. 2.7 ± 0.4 mmol/L, P = 0.002) and second glucagon bolus (4.1 ± 0.2 vs. 5.6 ± 0.5 mmol/L, P = 0.002).

    Insulin degludec (IDeg) is an ultra-long-acting insulin that has a smooth time/action profile over more than 42h. The present study compared the effects of IDeg and insulin glargine (IGlar) on HbA1c reduction and on within-subject day-to-day variability of fasting blood glucose (FBG) in insulin-naïve patients with type 2 diabetes. Eligible patients were randomly allocated at a 3:1 ratio to receive once-daily IDeg (n=31) or IGlar (n=12). Both basal insulins were administered before breakfast and titrated to achieve a target FBG <110mg/dl. The primary endpoints were the change in HbA1c from baseline to 24weeks of treatment, as well as the standard deviation (SD) and coefficient of variation (CV) of FBG from 8 to 12weeks and from 20 to 24weeks. Secondary endpoints included the QOL evaluated by the Diabetes Therapy-Related QOL questionnaire. After 24weeks, HbA1c was decreased by 1.6% in the IDeg group and 1.7% in the IGlar at the same insulin dosage. At 24weeks, FBG was significantly lower in the IDeg group than in the IGlar group and the CV of FBG was significantly smaller in the IDeg group. The frequency of total and severe hypoglycemic episodes did not differ between the groups. In the IDeg group, QOL showed significant improvement regarding anxiety and dissatisfaction with treatment. Treatment with IDeg or IGlar achieved similar improvement in glycemic control in insulin-naïve patients with type 2 diabetes. The day-to-day variation of FBG was smaller in patients receiving IDeg.

    Gestational diabetes mellitus (GDM) is associated with an increased prevalence of fetal and maternal complications primarily caused by maternal hyperglycemia, which results in abnormal fetal growth. Diet modification is a common first step in the treatment of GDM, followed by antidiabetic pharmacotherapy if this approach fails. Insulin therapy is generally accepted; however, oral hypoglycemic agents have been used in this population. In this prospective, randomised study, we compared maternal metabolic status after treatment with insulin or metformin. Pregnant women (gestational age: ≥ 20 weeks) with GDM requiring medical hypoglycemic treatment were randomly allocated to the Metformin (n = 35) or Insulin (n = 43) Groups. Maternal metabolic status - assessed by glycated hemoglobin (HBA1c) level, glycemic profile, insulin concentration, Homeostatic Model Assessment - Insulin Resistance index, and lipids - was recorded at booking and throughout pregnancy. The characteristics of the study group were: maternal age 33.5 ± 5.9 years, gestational age at baseline 28.5 ± 3.5 weeks, prepregnancy body mass index (BMI) 32.2 ± 3.5 kg/m(2), HbA1c at baseline 5.6 ± 0.6%, and average daily glycemia 5.9 ± 0.6 mmol/dl. Fasting glycemia at term was significantly lower in the Insulin Group but there were no significant differences in mean daily glycemia, HbA1c and BMI at term between the groups. Longitudinally, there was a small but significant increase in BMI and a significant increase in high-density lipoprotein-cholesterol in the Insulin Group and a significant increase in the atherogenic index of plasma (AIP) and a trend towards higher triglycerides in the Metformin Group. Both fasting and average daily glycemia were significantly reduced following treatment in both groups. No such change was evident for HbA1c. In a relative risk analysis, metformin treatment was associated with an insignificant elevated risk of HbA1c, triglycerides and lipid indices falling within the

  2. Mechanisms of insulin resistance in obesity

    Obesity increases the risk for type 2 diabetes through induction of insulin resistance. Treatment of type 2 diabetes has been limited by little translational knowledge of insulin resistance although there have been several well-documented hypotheses for insulin resistance. In those hypotheses, inflammation, mitochondrial dysfunction, hyperinsulinemia and lipotoxicity have been the major concepts and have received a lot of attention. Oxidative stress, endoplasmic reticulum (ER) stress, genetic background, aging, fatty liver, hypoxia and lipodystrophy are active subjects in the study of these concepts. However, none of those concepts or views has led to an effective therapy for type 2 diabetes. The reason is that there has been no consensus for a unifying mechanism of insulin resistance. In this review article, literature is critically analyzed and reinterpreted for a new energy-based concept of insulin resistance, in which insulin resistance is a result of energy surplus in cells. The energy surplus signal is mediated by ATP and sensed by adenosine monophosphate-activated protein kinase (AMPK) signaling pathway. Decreasing ATP level by suppression of production or stimulation of utilization is a promising approach in the treatment of insulin resistance. In support, many of existing insulin sensitizing medicines inhibit ATP production in mitochondria. The effective therapies such as weight loss, exercise, and caloric restriction all reduce ATP in insulin sensitive cells. This new concept provides a unifying cellular and molecular mechanism of insulin resistance in obesity, which may apply to insulin resistance in aging and lipodystrophy. PMID:23471659

    Perennial allergic rhinitis impairs social life, but it is not known whether quality of life may be improved when patients are treated with an H1-blocker. A randomized, double-blind, placebo-controlled study was carried out with cetirizine to assess the effect of this drug on quality of life. Two hundred seventy-four patients with perennial allergic rhinitis were tested. Quality of life was measured by using the Medical Outcome Study Short-Form Health Survey (SF-36) questionnaire. After a 2-week run-in period, cetirizine, 10 mg once daily, (136 patients) or placebo (138 patients) was given for the next 6 weeks. The SF-36 questionnaire was administered after the run-in period (at the start of treatment) and after 1 and 6 weeks of treatment. Symptom-medication scores were measured daily during the study. After the run-in period (baseline), there were no significant differences between the cetirizine and placebo groups in terms of symptoms or quality-of-life scores. After 6 weeks of treatment, percentage of days without rhinitis or with only mild rhinitis symptoms was significantly greater in the cetirizine group in comparison with the placebo group (p < 0.0001, Mann-Whitney U test). All of the nine quality-of-life dimensions were significantly improved (from p = 0.01 to p < 0.0001, Mann-Whitney U test) after 1 and 6 weeks of cetirizine treatment compared with placebo. There was no improvement in the placebo group. This study is the first to demonstrate that an H1-blocker, cetirizine, can improve quality of life for patients with perennial allergic rhinitis.

    A validation study was conducted to evaluate the psychometric properties of the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Endometrial Cancer Module (EORTC QLQ-EN24). This module was designed to assess disease and treatment specific aspects of the quality of life (QoL) of patients with endometrial cancer. Two hundred and sixty-eight women with endometrial cancer were recruited in different phases of treatment: after pelvic surgery (Group 1); during adjuvant chemotherapy and/or radiotherapy (Group 2); after completion of treatment (Group 3). Patients completed the EORTC QLQ-C30, the endometrial cancer module and a short debriefing questionnaire. Multi-trait scaling analyses confirmed the hypothesised scale structure of the QLQ-EN24. Internal consistency reliability was good with Cronbach's alpha coefficients ranging from 0.74 to 0.86 (lymphoedema 0.80, urological symptoms 0.75, gastrointestinal symptoms 0.74, body image problems 0.86 and sexual/vaginal problems 0.86). Convergent and discriminant validity did not show any scaling errors for the subscales. The QLQ-EN24 module discriminated well between clinically different groups of patients. All items exhibited a high completion rate with less than 2% missing values except for the sexuality items (19%). The validation study supports the reliability, the convergent and divergent validity of the EORTC QLQ-EN24. This newly developed QLQ-EN24 module is a useful instrument for the assessment of the QoL in patients treated for endometrial cancer in clinical trials. Copyright © 2010 Elsevier Ltd.

    The Suleiman mountainous region is an important cradle of animal domestication and the habitat of many indigenous livestock breeds. The dromedary camel is a highly appreciated and valued animal and represents an important genetic resource. Camel herders, living in remote areas, have developed their own ways to treat diseases in camels, based on a long time of experience. Information about the diseases and the ethnoveterinary practices performed was collected from a total of 90 herders and healers by interviews and participant observations. The respondents classified the diseased in major and minor fractions. Clinical signs were given in detail. Mange followed by trypanosomosis and orf were considered the most prevalent diseases, and also caused the greatest economic losses. Orf was regarded the most complex disease. The season was considered to have great influence on the occurrence of the diseases. A variety of different treatments were described, such as medicinal plants, cauterization, odorant/fly repellents, pesticides, larvicides, cold drink, yogurt and supportive therapy (hot food, hot drink). There is paramount need to document and validate the indigenous knowledge about animal agriculture in general and ethnoveterinary practices in particular. This knowledge is rapidly disappearing and represents a cultural heritage as well as a valuable resource for attaining food security and sovereignty.

    To estimate the costs associated with a flash glucose monitoring system as a replacement for routine self-monitoring of blood glucose (SMBG) in patients with type 1 diabetes mellitus (T1DM) using intensive insulin, from a UK National Health Service (NHS) perspective. The base-case cost calculation was created using the maximum frequency of glucose monitoring recommended by the 2015 National Institute for Health and Care Excellence guidelines (4-10 tests per day). Scenario analyses considered SMBG at the frequency observed in the IMPACT clinical trial (5.6 tests per day) and at the frequency of flash monitoring observed in a real-world analysis (16 tests per day). A further scenario included potential costs associated with severe hypoglycaemia. In the base case, the annual cost per patient using flash monitoring was £234 (19%) lower compared with routine SMBG (10 tests per day). In scenario analyses, the annual cost per patient of flash monitoring compared with 5.6 and 16 SMBG tests per day was £296 higher and £957 lower, respectively. The annual cost of severe hypoglycaemia for flash monitoring users was estimated to be £221 per patient, compared with £428 for routine SMBG users (based on 5.6 tests/day), corresponding to a reduction in costs of £207. The flash monitoring system has a modest impact on glucose monitoring costs for the UK NHS for patients with T1DM using intensive insulin. For people requiring frequent tests, flash monitoring may be cost saving, especially when taking into account potential reductions in the rate of severe hypoglycaemia. Copyright © 2018 The Authors.

    Protein kinase B (Akt/PKB) is a Ser/Thr kinase that is involved in the regulation of cell proliferation/survival through mammalian target of rapamycin (mTOR) and the regulation of glycogen metabolism through glycogen synthase kinase 3β (GSK-3β) and glycogen synthase (GS). Rapamycin is an inhibitor of mTOR. The objective of this study was to investigate the effects of rapamycin pretreatment on the insulin mediated phosphorylation of Akt/PKB phosphorylation and GS activity in parental HepG2 and HepG2 cells with overexpression of constitutively active Akt1/PKB-α (HepG2-CA-Akt/PKB). Rapamycin pretreatment resulted in a decrease (20-30%) in the insulin mediated phosphorylation of Akt1 (Ser 473) in parental HepG2 cells but showed an upregulation of phosphorylation in HepG2-CA-Akt/PKB cells. Rictor levels were decreased (20-50%) in parental HepG2 cells but were not significantly altered in the HepG2-CA-Akt/PKB cells. Furthermore, rictor knockdown decreased the phosphorylation of Akt (Ser 473) by 40-60% upon rapamycin pretreatment. GS activity followed similar trends as that of phosphorylated Akt and so with rictor levels in these cells pretreated with rapamycin; parental HepG2 cells showed a decrease in GS activity, whereas as HepG2-CA-Akt/PKB cells showed an increase in GS activity. The changes in the levels of phosphorylated Akt/PKB (Ser 473) correlated with GS and protein phoshatase-1 activity

    To evaluate the glycaemic control achieved by prandial once-daily insulin glulisine injection timing adjustment, based on a continuous glucose monitoring sensor, in comparison to once-daily insulin glulisine injection before breakfast in patients with type 2 diabetes who are uncontrolled with once-daily basal insulin glargine. This was a 24-week open-label, randomized, controlled, multicentre trial. At the end of an 8-week period of basal insulin optimization, patients with HbA1c ≥ 7.5% and FPG sensor) or arm B (sensor) to receive 16-week intensified prandial glulisine treatment. Patients in arm A received pre-breakfast glulisine, and patients in arm B received glulisine before the meal with the highest glucose elevation based on sensor data. The primary outcome was mean HbA1c at week 24 and secondary outcomes included rates of hypoglycaemic events and insulin dosage. A total of 121 patients were randomized to arm A (n = 61) or arm B (n = 60). There was no difference in mean HbA1c at week 24 between arms A and B (8.5% ± 1.2% vs 8.4% ± 1.0%; P = .66). The prandial insulin glulisine dosage for arm A and arm B was 9.3 and 10.1 units, respectively (P = .39). The frequency of hypoglycaemic events did not differ between study arms (36.1% vs 51.7%; P = .08). Using a CGM sensor to identify the meal with the highest glucose excursion and adjusting the timing of prandial insulin treatment did not show any advantage in terms of glycaemic control or safety in our patients. © 2018 The Authors.

    Insulin dose self-adjustment is an essential part of intensified insulin therapy - nowadays the routine treatment of type 1 diabetes (DM1). The aim of this study was to evaluate principles and frequency of insulin dose self-adjustments in people with DM1 before and one year after participating in a structured diabetes treatment and teaching programme (DTTP) and to determine to which extent the patients followed the way they had been trained. 72 people with DM1 were interviewed before participation in our inpatient (32/72) or outpatient (40/72) DTTP. Sixty-six participants (91.7%) were followed up after one year. The number of adaptations of the insulin dose by the patients was recorded from 28days of the patients' diary. The ability to find the correct dose was tested using five different examples. Metabolic control improved significantly after one year (7.9±1.0 to 7.5±0.8%, p=0.004). The participants performed 86.0±37.1 insulin dosage adaptations per 28days before the DTTP. After one year the frequency increased significantly to 99.1±30.7 per 28days (p=0.011). Before the DTTP, 42 of 72 patients (58.3%) adjusted their insulin dose to correct high blood glucose levels by adjustment rules (factor for correction or correction scheme) and 20 of 72 people (27.8%) by personal experience/feeling. One year after the DTTP, 73% (48/66) used adjustment rules. After participating in an structured education programme, patients adjusted their insulin dosage more frequently. Metabolic control improved despite the fact that many patients did not strictly apply the rules they had been trained for. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    There is a lack of instruments that focus on the specific health-related quality of life (HRQOL) issues that affect older people with cancer. The aim of this study was to develop a HRQOL questionnaire module to supplement the European Organisation for Research and Treatment of Cancer (EORTC) core questionnaire, the EORTC QLQ-C30 for older (>70years) patients with cancer. Phases 1-3 were conducted in seven countries following modified EORTC Quality of Life Group guidelines for module development. Phase 1: potentially relevant issues were identified by a systematic literature review, a questionnaire survey of 17 multi-disciplinary health professionals and two rounds of qualitative interviews. The first round included 9 patients aged >70. The second round was a comparative series of interviews with 49 patients >70years with a range of cancer diagnoses and 40 patients aged 50-69years matched for gender and disease site. In Phase 2 the issues were formulated into a long provisional item list. This was administered in Phase 3 together with the QLQ-C30 to two further groups of cancer patients aged >70 (n=97) or 50-69years (n=85) to determine the importance, relevance and acceptability of each item. Redundant and duplicate items were removed; issues specific to the older group were selected for the final questionnaire. In Phase 1, 75 issues were identified. These were reduced in Phase 2 to create a 45 item provisional list. Phase 3 testing of the provisional list led to the selection of 15 items with good range of response, high scores of importance and relevance in the older patients. This resulted in the EORTC QLQ-ELD15, containing five conceptually coherent scales (functional independence, relationships with family and friends, worries about the future, autonomy and burden of illness). The EORTC QLQ-ELD15 in combination with the EORTC QLQ-C30 is ready for large-scale validation studies, and will assess HRQOL issues of most relevance and concern for older people with

    We have previously shown that aerosolized liposomes with dipalmitoyl phosphatidylcholine (DPPC) enhance the pulmonary absorption of encapsulated insulin. In this study, we aimed to compare insulin encapsulated into the liposomes versus co-administration of empty liposomes and unencapsulated free insulin, where the DPCC liposomes would serve as absorption enhancer. The present study provides the useful information for development of noninvasive treatment of diabetes. Co-administration of empty DPPC liposomes and unencapsulated free insulin was investigated in vivo to assess the potential enhancement in protein pulmonary absorption. Co-administration was compared to DPPC liposomes encapsulating insulin, and free insulin. DPPC liposomes enhanced the pulmonary absorption of unencapsulated free insulin; however, the enhancing effect was lower than that of the DPPC liposomes encapsulating insulin. The mechanism of the pulmonary absorption of unencapsulated free insulin by DPPC liposomes involved the opening of epithelial cell space in alveolar mucosa, and not mucosal cell damage, similar to that of the DPPC liposomes encapsulating insulin. In an in vitro stability test, insulin in the alveolar mucus layer that covers epithelial cells was stable. These findings suggest that, although unencapsulated free insulin spreads throughout the alveolar mucus layer, the concentration of insulin released near the absorption surface is increased by the encapsulation of insulin into DPPC liposomes and the absorption efficiency is also increased. We revealed that the encapsulation of insulin into DPPC liposomes is more effective for pulmonary insulin absorption than co-administration of DPPC liposomes and unencapsulated free insulin.

    Despite increased efforts in preventing the occurrence of metabolic disorders in transition cows, hyperketonemia remains a frequent early-lactation metabolic disease affecting an average of 40% of cows in herds in the United States. Despite the demonstrated economic effect of this disorder, controlled clinical trials comparing different treatment strategies in affected cows are lacking. The objective of our study was to investigate the effect of treatment with intravenous glucose, oral propylene glycol, or a combination of both on the reduction in blood β-hydroxybutyrate (BHB) concentrations of early-lactation hyperketonemic dairy cows. Multiparous Holstein cows between 3 to 9 d in milk were screened for hyperketonemia using a handheld meter 3 times per week, and enrolled at whole blood BHB concentration ≥1.2 mmol/L to 1 of 4 treatment groups: (1) 500 mL of a 50% dextrose solution i.v. once daily for 3 d (GLU, n = 9), (2) 300 mL of propylene glycol as a drench once daily for 3 d (PG, n = 9), (3) a combination treatment of a 500 mL of 50% dextrose solution i.v. and 300 mL of propylene glycol orally once daily for 3 d (GLU+PG, n = 8), or (4) an untreated control group (CTRL, n = 8). Blood samples were collected immediately before as well as at 1, 2, 4, 8, 12, 24, 36, 48, 60, and 72 h after administration of the first treatment through a jugular catheter and 3 times per week thereafter from coccygeal vessels. Concentrations of BHB were measured in whole blood, and plasma samples were analyzed for glucose, fatty acid (NEFA), insulin, glucagon, and electrolyte concentrations. The EDTA-anticoagulated blood samples were assessed for red blood cell indices, and smears were made for evaluation of red blood cell morphology. Outcomes were analyzed using repeated measures analysis. Overall least squares means (95% CI) of whole blood BHB concentrations between 1 h and d 11 relative to first treatment were 1.11 (0.95 to 1.30), 1.26 (1.07 to 1.47), 0.96 (0.81 to 1.13), and 1

    Research conducted during the last decades has provided increasing evidence for the use of psychological treatments for a number of psychiatric disorders and somatic complaints. However, by focusing only on the positive outcomes, less attention has been given to the potential of negative effects. Despite indications of deterioration and other adverse and unwanted events during treatment, little is known about their occurrence and characteristics. Hence, in order to facilitate research of negative effects, a new instrument for monitoring and reporting their incidence and impact was developed using a consensus among researchers, self-reports by patients, and a literature review: the Negative Effects Questionnaire. Participants were recruited via a smartphone-delivered self-help treatment for social anxiety disorder and through the media (N = 653). An exploratory factor analysis was performed, resulting in a six-factor solution with 32 items, accounting for 57.64% of the variance. The derived factors were: symptoms, quality, dependency, stigma, hopelessness, and failure. Items related to unpleasant memories, stress, and anxiety were experienced by more than one-third of the participants. Further, increased or novel symptoms, as well as lack of quality in the treatment and therapeutic relationship rendered the highest self-reported negative impact. In addition, the findings were discussed in relation to prior research and other similar instruments of adverse and unwanted events, giving credence to the items that are included. The instrument is presently available in eleven different languages and can be freely downloaded and used from www.neqscale.com. PMID:27331907

    The health-related quality of life (HRQOL) after treatment of prostate cancer is examined using a new HRQOL tool. HRQOL, based on the expanded prostate cancer index composite (EPIC) and SF-8 questionnaires, was prospectively compared after either a radical retropubic prostatectomy (RRP) or a permanent prostate brachytherapy (PPB) at a single institute. Between October 2005 and June 2007, 96 patients were treated by an RRP and 88 patients were treated by a PPB. A HRQOL survey was completed at baseline, and at 1, 3, 6 and 12 months after treatment, prospectively. The general HRQOL in the RRP and PPB groups was not different after 3 months. However, at baseline and 1 month after treatment, the mental component summary was significantly better in the PPB group than in the RRP group. Moreover, the disease-specific HRQOL was worse regarding urinary and sexual functions in the RRP group. Urinary irritative/obstructive was worse in the PPB group, but urinary incontinence was worse in the RRP group and had not recovered to baseline after 12 months. The bowel function and bother were worse in the PPB group than in the RRP group after 3 months. In the RRP group, the patients with nerve sparing demonstrated the same scores in sexual function as the PPB group. This prospective study revealed the differences in the HRQOL after an RRP and PPB. Disease-specific HRQOL is clarified by using EPIC survey. These results will be helpful for making treatment decisions. (author)

    To study clinical inertia in the management of oral hypoglycemic agents (OHA) in non-insulin treated patients with type 2 diabetes mellitus (T2DM) in Spain. Epidemiological, cross-sectional, retrospective (2 years), multicenter study. Clinical inertia was measured as the total number of patients without OHA treatment intensification divided by the total number of patients with inadequate HbA1c values (≥7%), multiplied by 100. Total clinical inertia (TCI) was the absence of OHA treatment intensification in all visits with a HbA1c≥7% values in the previous 2 years; partial clinical inertia (PCI) occurred when this absence only occurred in some of these visits. We assessed OHA treatment compliance with the Morisky-Green test. We included 2,971 patients, 1,416 adequately controlled (HbA1c<7%) and 1,555 inadequately controlled (HbA1c≥7%). PCI prevalence was 52.5%(95% confidence interval [95% CI] 52.4-52.6%) while TCI prevalence was 12.8% (95% CI 12.2-13.8%). PCI was lower in patients adequately controlled as compared with those inadequately controlled (31.4% vs. 71.8%; P<.001). PCI was associated with sedentary lifestyle, hypertension and higher prevalence of micro and macrovascular complications. Only 38.0% of patients were compliant with the OHA treatment, being this percentage even lower in subjects with ICP. Two variables were independently associated with ICP: female sex (odds ratio [OR] 1.43; 95% CI 1.09-1.86%) and a shorter duration of DM2 (OR 0.98; 95% CI 0.95-0.99). One out of 2 patients with T2DM and treated with OHA without insulin suffer from PCI. Only 4 out of 10 patients are compliant with OHA treatment. Female sex and a shorter duration of T2DM are independently associated with PCI. Copyright © 2012 Elsevier España, S.L. All rights reserved.

At baseline glycaemic control was poor for both insulin naïve (mean HbA1c: 8.7%) and insulin user (mean HbA1c: 9.2%) groups. After 24 weeks of treatment, both the groups showed improvement in HbA1c (insulin naïve: -1.4%, insulin users: -1.8%). SADRs including major hypoglycaemic events or episodes did not occur in any of the study patients. Starting or switching to insulin analogues was associated with improvement in glycaemic control with a low rate of hypoglycaemia.

    Both attention-deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are frequently accompanied by serious aggression that requires psychiatric treatment. However, little is known about the experiences psychiatrists have had using pharmacotherapy to treat aggression in patients who have both ASD and ADHD (ASD/ADHD). The purpose of this study was to examine the experiences of Japanese child and adolescent psychiatrists in prescribing medication for aggression in patients with ASD/ADHD. A prospective questionnaire was mailed to 2001 psychiatrists affiliated with the Japanese Society for Child and Adolescent Psychiatry. Multivariate logistic regression analysis was used to identify factors predicting the outcome of pharmacotherapeutic treatment of aggression in pediatric and adolescent patients with ASD/ADHD. Of 2001 psychiatrists, 571 (28.5%) completed the full questionnaire (final sample). Of these, 488 (85.4%) prescribed psychotropic medication in treating pediatric and adolescent patients with ASD/ADHD, 299 (61.3%) of them doing so to treat aggression. Prescribers' duration of practice (odds ratio, 1.055; P = 0.038) and patient symptoms of residual impulsivity (odds ratio, 2.479; P = 0.039) increased the odds of prescribing psychotropic medications to treat aggression in these patients. The respondents reported a similar effect for patients with ADHD/ASD compared with those with ADHD only in treating aggression. Japanese psychiatrists tended to prescribe psychotropic medication for aggression in pediatric and adolescent patients with ASD/ADHD. Future studies examining aggression in pediatric and adolescent patients with ASD/ADHD should aim to accumulate evidence for the use of psychotropic medications, which could help clinicians make better decisions. © 2017 The Authors.

    Assessing functional outcome from patient-based outcomes questionnaires are essential to the evaluation of adolescent idiopathic scoliosis surgical treatment At the minimum follow-up of 2 years, 45 operated on adolescent idiopathic scoliosis patients were mailed the French version of the Scoliosis Research Society Outcome Instrument (SRS-22) questionnaires containing items on pain, activities of daily living, and satisfaction. Mean values of the SRS-22 domains were 3,66 for the Pain domain, 3,85 for the Self-perceived image domain, 4,32 for the Function domain, 3,52 for the Mental health domain and 4,12 for the Global satisfaction with management domain. Mean value of the global SRS-22 score was 3,88. We showed no differences in functional SRS-22 health status in patients according to the type of curve (Lenke classification). We showed statistically significant correlations between the gain of Cobb angle and Patients self-image and function domain scores. There was a statistically significant correlation between preoperative Cobb angle and patient satisfaction with management. Even if Function and Self-image scores in our patients are close to control group values, indicating good short to mid-term outcome of surgical treatment, scores for pain and mental health status were significantly lower in patients than controls. Long-term follow-up studies conducted by multiple surgeons over successive generations are mandatory to assess clinical significance of these differences. Level IV. Retrospective study.

    Chronic low grade inflammation is closely linked to obesity-associated insulin resistance. To examine how administration of the anti-inflammatory compound indomethacin, a general cyclooxygenase inhibitor, affected obesity development and insulin sensitivity, we fed obesity-prone male C57BL/6J mice...... a high fat/high sucrose (HF/HS) diet or a regular diet supplemented or not with indomethacin (±INDO) for 7 weeks. Development of obesity, insulin resistance, and glucose intolerance was monitored, and the effect of indomethacin on glucose-stimulated insulin secretion (GSIS) was measured in vivo...... and in vitro using MIN6 β-cells. We found that supplementation with indomethacin prevented HF/HS-induced obesity and diet-induced changes in systemic insulin sensitivity. Thus, HF/HS+INDO-fed mice remained insulin-sensitive. However, mice fed HF/HS+INDO exhibited pronounced glucose intolerance. Hepatic glucose...

    Full Text Available Larix laricina K. Koch is a medicinal plant belonging to traditional pharmacopoeia of the Cree of Eeyou Istchee (Eastern James Bay area of Canada. In vitro screening studies revealed that, like metformin and rosiglitazone, it increases glucose uptake and adipogenesis, activates AMPK, and uncouples mitochondrial function. The objective of this study was to evaluate the antidiabetic and antiobesity potential of L. laricina in diet-induced obese (DIO C57BL/6 mice. Mice were subjected for eight or sixteen weeks to a high fat diet (HFD or HFD to which L. laricina was incorporated at 125 and 250 mg/kg either at onset (prevention study or in the last 8 of the 16 weeks of administration of the HFD (treatment study. L. laricina effectively decreased glycemia levels, improved insulin resistance, and slightly decreased abdominal fat pad and body weights. This occurred in conjunction with increased energy expenditure as demonstrated by elevated skin temperature in the prevention study and improved mitochondrial function and ATP synthesis in the treatment protocol. L. laricina is thus a promising alternative and complementary therapeutic approach for the treatment and care of obesity and diabetes among the Cree.

    Full Text Available BackgroundIn Korea, the costs associated with self-monitoring of blood glucose (SMBG for patients with type 2 diabetes mellitus (T2DM under insulin treatment have been reimbursed since November 2015. We investigated whether this new reimbursement program for SMBG has improved the glycemic control in the beneficiaries of this policy.MethodsAmong all adult T2DM patients with ≥3 months of reimbursement (n=854, subjects without any changes in anti-hyperglycemic agents during the study period were selected. The improvement of glycosylated hemoglobin (HbA1c was defined as an absolute reduction in HbA1c ≥0.6% or an HbA1c level at follow-up <7%.ResultsHbA1c levels significantly decreased from 8.5%±1.3% to 8.2%±1.2% during the follow-up (P<0.001 in all the study subjects (n=409. Among them, 35.5% (n=145 showed a significant improvement in HbA1c. Subjects covered under the Medical Aid system showed a higher prevalence of improvement in HbA1c than those with medical insurance (52.2% vs. 33.3%, respectively, P=0.012. In the improvement group, the baseline HbA1c (P<0.001, fasting C-peptide (P=0.016, and daily dose of insulin/body weight (P=0.024 showed significant negative correlations with the degree of HbA1c change. Multivariate analysis showed that subjects in the Medical Aid system were about 2.5-fold more likely to improve in HbA1c compared to those with medical insurance (odds ratio, 2.459; 95% confidence interval, 1.138 to 5.314; P=0.022.ConclusionThe reimbursement for SMBG resulted in a significant improvement in HbA1c in T2DM subjects using insulin, which was more prominent in subjects with poor glucose control at baseline or covered under the Medical Aid system.

    The coexistence of two diseases associated with different metabolic disorders is a very rare event. Some associations, although sporadic, can be particularly challenging both in terms of diagnostic and therapeutic management and in terms of theoretical perspective. Here, we report a child affected by type 1 diabetes mellitus (T1DM) and glutaric aciduria type 1 (GA1). The child was diagnosed with classical T1DM at 15 months of age, with a tendency toward hypoglycemia. A few months later, during an acute intercurrent infective episode, the child displayed acute hypotonia of the lower limbs and limbs dystonia. A brain MRI showed bilateral striatal necrosis, suggesting GA1 diagnosis. Treatment with a low-lysine dietary regimen and carnitine supplementation was started and resulted in an improvement in metabolic control and a reduction of hypoglycemic episodes along with an increasing in insulin daily dose. After 2 years, the neurological outcome consisted of a reduction in dystonic movements and a metabolic stability of both diseases. This case provides some insight into the reciprocal interconnections between the two metabolic disorders. Similar pathogenic mechanisms responsible for the neuronal injury might have impacted each other, and a strict relationship between a specific aspect of GA1-impaired metabolism and glucose homeostasis might explain how the tailored management of GA1 was not only effective in controlling the disease, but it also resulted in an improvement in the control of the glycemic profile. What in known: • Glutaric aciduria type 1 (GA1) usually presents in childhood with severe and possibly irreversible neuronal damage, triggered by a catabolic stress • The association of GA1 with other diseases, including type 1 diabetes mellitus (T1DM), is a rare event, complicating the treatment management What is new: • Insulin treatment has a role in preventing GA1 metabolic decompensation, even in the catabolic condition of hypoglycemia • Promoting

    Radioimmunoassay of insulin in rat plasma using a popular method involving charcoal-separation of free and antibody-bound insulin was found to be unsatisfactory despite inclusion in standard tubes of insulin-free plasma prepared in either of two ways. Insulin-free plasma and untreated plasma had different effects on adsorption of free insulin to the charcoal. It was concluded that separation with charcoal is very sensitive to any prior treatment of the plasma. Particular care must be taken to ensure that hormone-free plasma is identical in all other respects to untreated plasma.

    To compare multiple doses of insulin and continuous insulin infusion therapy as treatment for type 1 diabetes melito. 40 patients with type 1 diabetes melito (21 female) with ages between 10 and 20 years (mean=14.2) and mean duration of diabetes of 7 years used multiple doses of insulin for at least 6 months and after that, continuous insulin infusion therapy for at least 6 months. Each one of the patients has used multiple doses of insulin and continuous insulin infusion therapy. For analysis of HbA1c, mean glycated hemoglobin levels (mHbA1c) were obtained during each treatment period (multiple doses of insulin and continuous insulin infusion therapy period). Although mHbA1c levels were lower during continuous insulin infusion therapy the difference was not statistically significant. During multiple doses of insulin, 14.2% had mHbA1c values below 7.5% vs. 35.71% while on continuous insulin infusion therapy; demonstrating better glycemic control with the use of continuous insulin infusion therapy. During multiple doses of insulin, 15-40 patients have severe hypoglycemic events versus 5-40 continuous insulin infusion therapy. No episodes of ketoacidosis events were recorded. This is the first study with this design comparing multiple doses of insulin and continuous insulin infusion therapy in Brazil showing no significant difference in HbA1c; hypoglycemic events were less frequent during continuous insulin infusion therapy than during multiple doses of insulin and the percentage of patients who achieved a HbA1c less than 7.5% was greater during continuous insulin infusion therapy than multiple doses of insulin therapy.

    Adipocytes treated with neuraminidase show markedly reduced responsiveness to insulin without any alteration in insulin binding. In addition, several studies have separately demonstrated both insulin resistance and decreases in membrane sialic acid content and associated biosynthetic enzymes in diabetes mellitus. In the present study, the authors investigated the role that sialic acid residues may play in insulin action and in the hepatic insulin resistance associated with nonketotic diabetes. Primary cultures of hepatocytes from normal rats treated with neuraminidase demonstrated a dose-dependent decrease in insulin-stimulated lipogenesis. At a concentration of neuraminidase that decreases insulin action by 50%, 23% of total cellular sialic acid content was released. Neuraminidase-releasable sialic acid was significantly decreased in hepatocytes from diabetic rats and this was associated with significant insulin resistance. Treatment of hepatocytes from diabetic rats with cytidine 5'-monophospho-N-acetylneuraminic acid (CMP-NANA) enhanced insulin responsiveness 39%. The enhanced insulin responsiveness induced by CMP-NANA was blocked by cytidine 5'-monophosphate (CMP) suggesting that the CMP-NANA effect was catalyzed by a cell surface sialyl-transferase. CMP reduced neuraminidase-releasable [ 14 C]sialic acid incorporation into hepatocytes by 43%. The data demonstrate a role for cell surface sialic acid residues in hepatic insulin action and support a role for decreased cell surface sialic acid residues in the insulin resistance of diabetes mellitus

    Full Text Available Insulin antibodies (IA associated with exogenous insulin administration seldom caused hypoglycemia and had different characteristics from insulin autoantibodies (IAA found in insulin autoimmune syndrome (IAS, which was first described by Dr Hirata in 1970. The characteristic of IAS is the presence of insulin-binding autoantibodies and related fasting or late postprandial hypoglycemia. Here, we report a patient with type 1 diabetes mellitus under insulin glargine and insulin aspart treatment who developed recurrent spontaneous post-absorptive hyperinsulinemic hypoglycemia with the cause probably being insulin antibodies induced by exogenous injected insulin. Examinations of serial sera disclosed a high titre of insulin antibodies (33%, normal <5%, high insulin concentration (111.9 IU/mL and undetectable C-peptide when hypoglycemia occurred. An oral glucose tolerance test revealed persistent high serum levels of total insulin and undetectable C-peptide. Image studies of the pancreas were unremarkable, which excluded the diagnosis of insulinoma. The patient does not take any of the medications containing sulfhydryl compounds, which had been reported to cause IAS. After administering oral prednisolone for 3 weeks, hypoglycemic episodes markedly improved, and he was discharged smoothly.

    Insulin adsorbs to plastic tubing, which decreases the concentration of an insulin solution delivered from an intravenous infusion set. Dwelling insulin within tubing before starting the infusion decreases adsorption but delays treatment initiation and wastes time in infusion preparation. The lack of data on dwell time effects results in wide variability in practice. We aim to determine the effect of dwell time on insulin concentration from intravenous infusion tubing. In this in vitro study, we used insulin solutions with concentrations of 0.1 unit/mL, 1 unit/mL, and 10 units/mL. Each solution dwelled in intravenous infusion sets for 0, 15, 30, or 60 min. After the dwell, we measured insulin concentrations from the solution bags and tubing. We repeated each insulin concentration-dwell time combination five times. Comparisons were performed using analyses of variance. For each of the three insulin concentrations, the mean insulin concentrations from the tubing were not significantly different between dwell times. Duration of dwell time did not affect insulin adsorption in polypropylene intravenous infusion sets. We recommend that following a 20-mL flush, insulin infusions can be started without any dwell time. Removal of dwell times may improve clinical practice by minimizing preparation time and will allow faster initiation of insulin infusion therapy.

  14. Negative Effects of Psychological Treatments: An Exploratory Factor Analysis of the Negative Effects Questionnaire for Monitoring and Reporting Adverse and Unwanted Events.

    Alexander Rozental

    Full Text Available Research conducted during the last decades has provided increasing evidence for the use of psychological treatments for a number of psychiatric disorders and somatic complaints. However, by focusing only on the positive outcomes, less attention has been given to the potential of negative effects. Despite indications of deterioration and other adverse and unwanted events during treatment, little is known about their occurrence and characteristics. Hence, in order to facilitate research of negative effects, a new instrument for monitoring and reporting their incidence and impact was developed using a consensus among researchers, self-reports by patients, and a literature review: the Negative Effects Questionnaire. Participants were recruited via a smartphone-delivered self-help treatment for social anxiety disorder and through the media (N = 653. An exploratory factor analysis was performed, resulting in a six-factor solution with 32 items, accounting for 57.64% of the variance. The derived factors were: symptoms, quality, dependency, stigma, hopelessness, and failure. Items related to unpleasant memories, stress, and anxiety were experienced by more than one-third of the participants. Further, increased or novel symptoms, as well as lack of quality in the treatment and therapeutic relationship rendered the highest self-reported negative impact. In addition, the findings were discussed in relation to prior research and other similar instruments of adverse and unwanted events, giving credence to the items that are included. The instrument is presently available in eleven different languages and can be freely downloaded and used from www.neqscale.com.

    Validity and reliability of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) had already been verified as the patients' self-rating assessment of low back pain and lumbar spinal disease and, the present study demonstrated the responsiveness of this measure. 192 subjects who were determined by medical instructors of the Japanese Society for Spine Surgery and Related Research were analyzed. They had completed a series of treatment and both surveys before and after the treatment. Authors investigated rates of concordance between assessment by physicians and subjective assessment by patients. The mean, standard deviation, minimum, 25th percentile, median, 75th percentile and maximum values for pre-treatment, post-treatment, and acquired points were calculated, and then, we also investigated the trend between subjective assessment by patients and mean acquired points for each JOABPEQ domain and substantial clinical benefit thresholds for the JOABPEQ. Symptom changes as assessed by physicians did not coincide with those by patients, and acquired points in each JOABPEQ domain were significantly increased with improved self-rating by patients. In addition, patients who rated symptom changes as "slightly improved" showed a mean acquired points of ≥20, and those reporting "improved" showed a 25th percentile points of the acquired points of ≥20 approximately. A significant correlation was noted between the self-rating of patients and acquired points JOABPEQ, suggesting that ≥20 acquired points can be interpreted as substantial clinical benefit thresholds for the JOABPEQ.

    Objective Complementary and alternative medicine (CAM) is commonly used by children with juvenile idiopathic arthritis (JIA), yet no validated questionnaires assess that use. The objective of this study was to develop child self- and parent proxy-report questionnaires assessing CAM use and to determine the face and content validity of the “Which Health Approaches and Treatments are you using?” (WHAT) questionnaires in pediatric rheumatology. Methods A sequential phased mixed methods approach was used to develop the questionnaires. A Delphi Survey of 126 experts followed by an interdisciplinary consensus conference of 14 stakeholders in CAM, general pediatrics and pediatric rheumatology was held to develop consensus on the content of the questionnaires using a nominal group technique. To determine face and content validity of the questionnaires, two groups, including (a) a purposive sample of 22 children with JIA 8 to 18 years and their parents from the Children’s Hospital of Eastern Ontario and the Hospital for Sick Children, and (b) 21 Canadian pediatric rheumatology experts, participated in interviews. Participants were independently asked about the goal, understandability and comprehensiveness of the WHAT questionnaires, as well as the relevance of items. Results Consensus was reached on 17 items of the WHAT questionnaires. The domains found to be relevant were child’s CAM use, factors associated with CAM use, perceived impact of CAM use, and communication about CAM. A total of 15 items in the parent proxy-report questionnaire and 13 items in the child report questionnaire showed adequate content validity. Conclusions Consensus was reached by experts on the content of a pediatric CAM questionnaire. Face and content validity testing and modifications made to the WHAT questionnaires have helped ensure adequate preliminary validity for use in pediatric rheumatology. This constitutes the basis for further testing of these questionnaires in pediatric

    Evidence from human clinical, epidemiological, and experimental animal models has clearly highlighted a link between the early life environment and an increased risk for a range of cardiometabolic disorders in later life. In particular, altered maternal nutrition, including both undernutrition and overnutrition, spanning exposure windows that cover the period from preconception through to early infancy, clearly highlight an increased risk for a range of disorders in offspring in later life. This process, preferentially termed "developmental programming" as part of the developmental origins of health and disease (DOHaD) framework, leads to phenotypic outcomes in offspring that closely resemble those of individuals with untreated growth hormone (GH) deficiency, including increased adiposity and cardiovascular disorders. As such, the use of GH as a potential intervention strategy to mitigate the effects of developmental malprogramming has received some attention in the DOHaD field. In particular, experimental animal models have shown that early GH treatment in the setting of poor maternal nutrition can partially rescue the programmed phenotype, albeit in a sex-specific manner. Although the mechanisms remain poorly defined, they include changes to endothelial function, an altered inflammasome, changes in adipogenesis and cardiovascular function, neuroendocrine effects, and changes in the epigenetic regulation of gene expression. Similarly, GH treatment to adult offspring, where an adverse metabolic phenotype is already manifest, has shown efficacy in reversing some of the metabolic disorders arising from a poor early life environment. Components of the GH-insulin-like growth factor (IGF)-IGF binding protein (GH-IGF-IGFBP) system, including insulin-like growth factor 1 (IGF-1), have also shown promise in ameliorating programmed metabolic disorders, potentially acting via epigenetic processes including changes in miRNA profiles and altered DNA methylation. However, as

    Diabetes mellitus type 1 is a chronic metabolic disorder, and its main characteristic is Hyperglycemia. It usually occurs in the early years because of the absolute or relative absence of the active insulin that is caused by the autoimmune disease of the beta cells of the pancreas. Despite the numerous researches and efforts of the scientists, the therapy for Diabetes type 1 is based on the substitution of insulin. Even though the principles of the therapy have not changed so much, still some important changes have occurred in the production and usage of insulin. Lately, the insulin pumps are more frequent in the therapy for Diabetes type 1. The functioning of the pump is based on the continuing delivery of insulin in a small dose ("the basal dose"), that keeps the level of glycemia in the blood constant. The increase of glycemia during the meal is reduced with the additional dose of insulin ("the bolus dose"). The use of the insulin pumps and the continuing glucose sensors has provided an easier and more efficient monitoring of the diabetes, a better metabolic control and a better life quality for the patient and his/her family. This work presents the way of automatic regulation of the basal dose of insulin through the synthesis of the functions of the insulin pump and the continuing glucose sensor. The aim is to give a contribution to the development of the controlling algorithm on the insulin pump for the automatic regulation of the glucose concentration in the blood. This could be a step further which is closer to the delivery of the dose of insulin that is really needed for the basic needs of the organism, and a significant contribution is given to the development of the artificial pancreas.

    What's known on the subject? and What does the study add? Studies on erectile dysfunction (ED) therapies rely heavily on patient-reported outcomes (PROs) to measure efficacy on treatment response. A challenge when using PROs is interpretation of the clinical meaning of changes in scores. A responder analysis provides a threshold score to indicate whether a change in score qualifies a patient as a responder. However, a major consideration with responder analysis is the sometimes arbitrary nature of defining the threshold for a response. By contrast, cumulative response curves (CRCs) display patient response rates over a continuum of possible thresholds, thus eliminating problems with a rigid threshold definition, allowing for a variety of response thresholds to be examined simultaneously, and encompassing all data. With respect to the psychosocial factors addressed in the Self-Esteem And Relationship questionnaire in ED, CRCs clearly, distinctly, and meaningfully highlighted the favourable profiles of responses to sildenafil compared with placebo. CRCs for PROs in urology can provide a clear, transparent and meaningful visual depiction of efficacy data that can supplement and complement other analyses. To use cumulative response curves (CRCs) to enrich meaning and enhance interpretation of scores on the Self-Esteem And Relationship (SEAR) questionnaire with respect to treatment differences for men with erectile dysfunction (ED). This post hoc analysis used data from all patients who took at least one dose of study drug and had at least one post-baseline efficacy evaluation in a previously published 12-week, multicentre, randomized, double-blind, placebo-controlled trial of flexible-dose (25, 50, or 100 mg) sildenafil citrate (Viagra) in adult men with ED who had scored ≤ 75 out of 100 on the Self-Esteem subscale of the SEAR questionnaire. CRCs were used on the numeric change in transformed SEAR scores from baseline to end-of-study for each SEAR component. The

    Insulin-like growth factor (IGF)-1 has shown some interesting results in studies examining its use as a hair-loss treatment. IGF-1 works by regulating cellular proliferation and migration during the development of hair follicles. Hepatotoxicity and myelotoxicity were evaluated in hamsters (Mesocricetus auratus) after topical application of the liquid gel vehicle (placebo), 1% IGF-1 or 3% IGF-1. No significant difference in the levels of aspartate aminotransferase or alanine aminotransferase was found between the control and treated groups. ELISA did not shown any increase in the plasma level of IGF-1. A haematopoietic niche was found, but it was not associated with myelotoxicity. Efficacy was determined by dermatoscopy analysis of hair density and microscopy analysis of hair diameter, with hair found to be thicker and with more rapid growth in the 3% group than in either the 1% group or the control group. These results strongly suggest that liposomal IGF-1 in a liquid gel formulation is a safe and efficient treatment for hair loss. © The Author(s). CED © 2012 British Association of Dermatologists.

    Full Text Available Objective. To compare dipeptidyl peptidase-4 (DPP-4 inhibitors with neutral protamine Hagedorn (NPH insulin, in terms of effectiveness and safety for the management of patients with type 2 diabetes mellitus (DM2 not controlled on metformin and sulfonylureas. Methods. A retrospective cohort study of individuals with DM2 newly dispensed with either DPP-4 inhibitors or NPH as third-line therapy, after metformin and sulfonylurea. Treatment discontinuation, macrovascular outcomes, and hypoglycemia were compared using multivariable Cox regression models, adjusted for sex, age, year of cohort entry, place of residence, hypertension, past history of hypoglycemia, diabetic ketoacidosis, comorbidities, and number of visits to emergency departments, outpatient physician, and hospitalizations. Results. Treatment discontinuation and hypoglycemia occurred more frequently with NPH than with DPP-4 inhibitor users. In the adjusted Cox model, the use of NPH compared to that of DPP-4 inhibitors was associated with a higher risk of discontinuation (HR: 1.33; 95% CI 1.27–1.40 and hypoglycemia (HR: 2.98; 95% CI 2.72–3.28. Risk of cardiovascular events was similar across groups. Conclusions. This real-world analysis suggests that DM2 patients initiating third-line therapy with NPH have poorer control of diabetes when compared to DPP-4 inhibitor initiators.

    A positive effect of fluoxetine has been shown in some children with autism. The present study was undertaken to correlate striatal dopamine transporter (DAT) binding and cerebrospinal fluid insulin-like growth factor-1 (CSF-IGF-1) with clinical response in autistic children (n=13, age 5-16 years) after a 6-month fluoxetine treatment. Good clinical responders (n=6) had a decrease (p=0.031) in DAT binding as assessed using single-photon emission computed tomography with [123I]-nor-β-CIT, whereas poor responders had a trend to an increase. An increase in CSF-IGF-1 (p=0.003) was detected after the treatment period, but no correlation between the clinical response and CSF-IGF-1 was found. In conclusion, fluoxetine decreases DAT binding indicating alleviation of the hyperdopaminergic state and increases CSF-IGF-1 concentration, which may also have a neuroprotective effect against dopamine-induced neurotoxicity in autistic children. © Georg Thieme Verlag KG Stuttgart · New York.

    1999-02-01

    The aim of insulin replacement therapy is to normalize blood glucose in order to reduce the complications of diabetes. The pharmacokinetics of the traditional insulin preparations, however, do not match the profiles of physiological insulin secretion. The introduction of the rDNA technology 20 years ago opened new ways to create insulin analogs with altered properties. Fast-acting analogs are based on the idea that an insulin with less tendency to self-association than human insulin would be more readily absorbed into the systemic circulation. Protracted-acting analogs have been created to mimic the slow, steady rate of insulin secretion in the fasting state. The present paper provides a historical review of the efforts to change the physicochemical and pharmacological properties of insulin in order to improve insulin therapy. The available clinical studies of the new insulins are surveyed and show, together with modeling results, that new strategies for optimal basal-bolus treatment are required for utilization of the new fast-acting analogs.

    Full Text Available Introduction. Insulin allergy is a rare complication of insulin therapy, especially in type 1 diabetes mellitus (T1DM. Key manifestations are hypersensitivity-related symptoms and poor metabolic control. T1DM, as well as insulin allergy, may develop in the context of autoimmune polyendocrine syndrome (APS, further complicating management. Case Report. A 17-year-old male patient, diagnosed with T1DM, was treated with various insulin therapy schemes over several months, which resulted in recurrent anaphylactoid reactions and poor glycemic control, after which he was referred to our Endocrinology and Immunology Department. A prick test was carried out for all commercially available insulin presentations and another insulin scheme was designed but proved unsuccessful. A desensitization protocol was started with Glargine alongside administration of Prednisone, which successfully induced tolerance. Observation of skin lesions typical of vitiligo prompted laboratory workup for other autoimmune disorders, which returned positive for autoimmune gastritis/pernicious anemia. These findings are compatible with APS type 4. Discussion. To our knowledge, this is the first documented case of insulin allergy in type 4 APS, as well as this particular combination in APS. Etiopathogenic components shared by insulin allergy and APS beg for further research in immunogenetics to further comprehend pathophysiologic aspects of these diseases.

    Full Text Available Today an obesity became the global epidemic striking both children, and adults and represents one of the most important problems of health care worldwide. Excess accumulation of fatty tissue is resulted by insulin resistance and a compensatory hyperinsulinaemia which are the main predictors of development of a diabetes mellitus type 2. Insulin resistance is also one of key links of a pathogenesis of such diseases as cardiovascular pathology, not-alcoholic fatty liver disease, a polycystic ovary syndrome, gestational diabetes and many others. Depression of sensitivity of tissues to insulin can be physiological reaction of an organism to stress factors and pathological process. The endogenic reasons also take part in development of insulin resistance besides factors of the external environment. The role of genetic predisposition, a subclinical inflammation of fatty tissue, thyroid hormones, adipokines and vitamin D in formation of this pathological process is studied. As insulin resistance takes part in a pathogenesis of various diseases, methods of its diagnostics and correction are of great importance in therapeutic practice. At purpose of treatment it is worth giving preference to the drugs which are positively influencing sensitivity of tissues to insulin.

    We studied the effect of 10-week treatment with intranasal insulin (0.5 IU/day) on glucose tolerance, glucose utilization, lipid metabolism, functions of pancreatic β cells, and insulin system in the liver of rats with cafeteria diet-induced metabolic syndrome. The therapy reduced body weight and blood levels of insulin, triglycerides, and atherogenic cholesterol that are typically increased in metabolic syndrome, normalized glucose tolerance and its utilization, and increased activity of insulin signaling system in the liver, thus reducing insulin resistance. The therapy did not affect the number of pancreatic islets and β cells. The study demonstrates prospects of using intranasal insulin for correction of metabolic parameters and reduction of insulin resistance in metabolic syndrome.

    The timely onset of stage II lactogenesis (OL) is important for successful breastfeeding and newborn health. Several risk factors for delayed OL are common in women with a history of gestational diabetes mellitus (GDM), which may affect their chances for successful breastfeeding outcomes. We investigated the prevalence and risk factors associated with delayed OL in a racially and ethnically diverse cohort of postpartum women with recent GDM. We analyzed data collected in the Study of Women, Infant Feeding and Type 2 Diabetes After GDM Pregnancy (SWIFT), which is a prospective cohort of women diagnosed with GDM who delivered at Kaiser Permanente Northern California hospitals from 2008 to 2011. At 6-9 wk postpartum, delayed OL was assessed by maternal report of breast fullness and defined as occurring after 72 h postpartum. We obtained data on prenatal course and postdelivery infant feeding practices from electronic medical records and in-person surveys. We used multivariable logistic regression models to estimate associations of delayed OL with prenatal, delivery, and postnatal characteristics. The analysis included 883 SWIFT participants who initiated breastfeeding and did not have diabetes at 6-9 wk postpartum. Delayed OL was reported by 33% of women and was associated with prepregnancy obesity (OR: 1.56; 95% CI: 1.07, 2.29), older maternal age (OR: 1.05; 95% CI: 1.01, 1.08), insulin GDM treatment (OR: 3.11; 95% CI: 1.37, 7.05), and suboptimal in-hospital breastfeeding (OR: 1.65; 95% CI: 1.20, 2.26). A higher gestational age was associated with decreased odds of delayed OL but only in multiparous mothers (OR: 0.79; 95% CI: 0.67, 0.94). One-third of women with recent GDM experienced delayed OL. Maternal obesity, insulin treatment, and suboptimal in-hospital breastfeeding were key risk factors for delayed OL. Early breastfeeding support for GDM women with these risk factors may be needed to ensure successful lactation. This trial was registered at clinicaltrials

    Contrary to the previous belief that insulin does not act in the brain, studies in the last three decades have demonstrated important roles of insulin and insulin signal transduction in various functions of the central nervous system. Deregulated brain insulin signaling and its role in molecular pathogenesis have recently been reported in Alzheimer's disease (AD). In this article, we review the roles of brain insulin signaling in memory and cognition, the metabolism of amyloid β precursor protein, and tau phosphorylation. We further discuss deficiencies of brain insulin signaling and glucose metabolism, their roles in the development of AD, and recent studies that target the brain insulin signaling pathway for the treatment of AD. It is clear now that deregulation of brain insulin signaling plays an important role in the development of sporadic AD. The brain insulin signaling pathway also offers a promising therapeutic target for treating AD and probably other neurodegenerative disorders.

    Type 2 diabetes and obesity are common metabolic disorders characterized by resistance to the actions of insulin to stimulate skeletal muscle glucose disposal. Insulin-resistant muscle has defects at several steps of the insulin-signaling pathway, including decreases in insulin-stimulated insulin receptor and insulin receptor substrate-1 tyrosine phosphorylation, and phosphatidylinositol 3-kinase (PI 3-kinase) activation. One approach to increase muscle glucose disposal is to reverse/improve these insulin-signaling defects. Weight loss and thiazolidinediones (TZDs) improve glucose disposal, in part, by increasing insulin-stimulated insulin receptor and IRS-1 tyrosine phosphorylation and PI 3-kinase activity. In contrast, physical training and metformin improve whole-body glucose disposal but have minimal effects on proximal insulin-signaling steps. A novel approach to reverse insulin resistance involves inhibition of the stress-activated protein kinase Jun N-terminal kinase (JNK) and the protein tyrosine phosphatases (PTPs). A different strategy to increase muscle glucose disposal is by stimulating insulin-independent glucose transport. AMP-activated protein kinase (AMPK) is an enzyme that works as a fuel gauge and becomes activated in situations of energy consumption, such as muscle contraction. Several studies have shown that pharmacologic activation of AMPK increases glucose transport in muscle, independent of the actions of insulin. AMPK activation is also involved in the mechanism of action of metformin and adiponectin. Moreover, in the hypothalamus, AMPK regulates appetite and body weight. The effect of AMPK to stimulate muscle glucose disposal and to control appetite makes it an important pharmacologic target for the treatment of type 2 diabetes and obesity.

    Full Text Available The brain represents an important site for the action of insulin. Besides the traditionally known importance in glucoregulation, insulin has significant neurotrophic properties and influences the brain activity: insulin influences eating behavior, regulates the storage of energy and several aspects concerning memory and knowledge. Insulin resistance and hyperinsulinism could be associated with brain aging, vascular and metabolic pathologies. Elucidating the pathways and metabolism of brain insulin could have a major impact on future targeted therapies.

    Full Text Available Diabetes is one of the most prevalent, costly, and debilitating diseases in the world. Pancreas and islet transplants have shown success in re-establishing glucose control and reversing diabetic complications. However, both are limited by donor availability, need for continuous immunosuppression, loss of transplanted tissue due to dispersion, and lack of vascularization. To overcome the limitations of poor islet availability, here, we investigate the potential of bone marrow–derived mesenchymal stem cells differentiated into islet-like insulin-producing aggregates. Islet-like insulin-producing aggregates, characterized by gene expression, are shown to be similar to pancreatic islets and display positive immunostaining for insulin and glucagon. To address the limits of current encapsulation systems, we developed a novel three-dimensional printed, scalable, and potentially refillable polymeric construct (nanogland to support islet-like insulin-producing aggregates’ survival and function in the host body. In vitro studies showed that encapsulated islet-like insulin-producing aggregates maintained viability and function, producing steady levels of insulin for at least 4 weeks. Nanogland—islet-like insulin-producing aggregate technology here investigated as a proof of concept holds potential as an effective and innovative approach for diabetes cell therapy.

    Full Text Available Abstract Background The course of barriers towards insulin therapy was analysed in three different groups of type 2 diabetic patients. This observational longitudinal study surveyed a three-month follow-up. Methods Participants in this study totalled 130 type 2 diabetic patients. The first subgroup was on insulin therapy at baseline (group 1: n = 57, age 55.6 ± 8.7 yrs, disease duration 12.7 ± 7.2 yrs, HbA1c 8.5 ± 1.6% and remained on insulin at follow-up. Of an initial 73 insulin-naïve patients, 44 were switched to insulin therapy (group 2: age 58.1 ± 6.8 yrs, disease duration 7.7 ± 5.0 yrs, HbA1c 9.1 ± 1.7% and 29 patients remained on an oral regimen (group 3: age 52.7 ± 10.7 yrs, disease duration 5.3 ± 4.6 yrs, HbA1c 8.3 ± 1.4%. Barriers towards insulin therapy were measured using the Insulin Treatment Appraisal Scale (ITAS. As generic instruments of health related quality of life patients completed also the Problem Areas of Diabetes Questionnaire (PAID, the WHO-5 Well-Being Scale (WHO-5, the Centre for Epidemiologic Studies Depression Scale (CES-D and the Trait Version of the State Trait Anxiety Inventory (STAI at baseline and at three-month follow-up. Results At the three-month follow-up, HbA1c had improved in all three groups (7.7 ± 1.2% vs. 7.1 ± 1.1% vs. 6.7 ± 0.8%. The course of negative appraisal of insulin therapy was significantly different in the three groups (p > .003: the ITAS score increased in patients remained on oral antidiabetic drugs (51.2 ± 12.2 to 53.6 ± 12.3, whereas it decreased in patients switched to insulin therapy (49.2 ± 9.8 to 46.2 ± 9.9 or remained on insulin treatment (45.8 ± 8.3 to 44.5 ± 8.0. Diabetes-related distress, trait anxiety, and well-being, showed a similar course in all three groups. The depression score improved significantly in patients switched to insulin treatment compared with patients remaining on insulin therapy. Conclusions In summary, this study suggests that a negative

    Headache disorders are both common and burdensome but, given the many people affected, provision of health care to all is challenging. Structured headache services based in primary care are the most efficient, equitable and cost-effective solution but place responsibility for managing most patients on health-care providers with limited training in headache care. The development of practical management aids for primary care is therefore a purpose of the Global Campaign against Headache. This manuscript presents an outcome measure, the Headache Under-Response to Treatment (HURT) questionnaire, describing its purpose, development, psychometric evaluation and assessment for clinical utility. The objective was a simple-to-use instrument that would both assess outcome and provide guidance to improving outcome, having utility across the range of headache disorders, across clinical settings and across countries and cultures. After literature review, an expert consensus group drawn from all six world regions formulated HURT through item development and item reduction using item-response theory. Using the American Migraine Prevalence and Prevention Study's general-population respondent panel, two mailed surveys assessed the psychometric properties of HURT, comparing it with other instruments as external validators. Reliability was assessed in patients in two culturally-contrasting clinical settings: headache specialist centres in Europe (n = 159) and primary-care centres in Saudi Arabia (n = 40). Clinical utility was assessed in similar settings (Europe n = 201; Saudi Arabia n = 342). The final instrument, an 8-item self-administered questionnaire, addressed headache frequency, disability, medication use and effect, patients' perceptions of headache "control" and their understanding of their diagnoses. Psychometric evaluation revealed a two-factor model (headache frequency, disability and medication use; and medication efficacy and headache control), with

Materials and Methods: Data was collected at baseline, at 12 weeks and at 24 weeks. This short communication presents the results for patients enrolled from Rajasthan, India. Results: A total of 477 patients were enrolled in the study. Four different insulin analogue regimens were used in the study. Patients had started on or were switched to biphasic insulin aspart (n = 340, insulin detemir (n = 90, insulin aspart (n = 37, basal insulin plus insulin aspart (n = 7 and other insulin combinations (n = 2. At baseline glycaemic control was poor for both insulin naïve (mean HbA 1 c: 8.3% and insulin user (mean HbA 1 c: 8.4% groups. After 24 weeks of treatment, both the groups showed improvement in HbA 1 c (insulin naïve: −0.9%, insulin users: −1.2%. Major hypoglycaemic events decreased from 0.5 events/patient-year to 0.0 events/patient-year in insulin naïve group while no change from baseline (1.3 events/patients-year was observed for insulin users. SADRs were not reported in any of the study patients. Conclusion: Starting or switching to insulin analogues was associated with improvement in glycaemic control with a low rate of hypoglycaemia.

    The metabolic flexibility is often impaired in diseases associated with obesity, and many studies are based on the hypothesis that dysfunction in peripheral tissues such as skeletal muscle, liver and adipose tissue represent the etiology of development of metabolic inflexibility. Experimental evidence shows that the use of phototherapy combined with exercise was effective in controlling the lipid profile, reducing the mass of adipose tissue, suggesting increased metabolic activity and changes in lipid metabolism. However, we found few data in the literature involving the use of phototherapy in association to physical training in the obese population. Thus, our objective was to evaluate the effects of exercise training (aerobic plus resistance exercises) plus phototherapy (laser, 808 nm) on metabolic profile and adiponectinemia in obese women. Sixty-four obese women (BMI 30-40 kg/m2 , age between 20 and 40 years old) were randomly assigned in two groups: Exercise Training plus SHAM group (ET-SHAM, n = 32) and Exercise Training plus Phototherapy group (ET-PHOTO, n = 32). The treatment consisted in physical exercise intervention and the individual application of phototherapy immediately after the end of the training session. However, in the ET-SHAM group the device was turned off simulating the phototherapy application (placebo effect). The study protocol lasted for 20 weeks and comprised of three weekly sessions of aerobic plus resistance training and application of phototherapy (when applicable). The body composition and metabolic parameters were assessed (HOMA, adiponectin, insulin, glucose). Comparing the magnitude of effects between groups (ET-PHOTO vs. ET-SHAM), we observed that physical training plus phototherapy was more effective than physical training in reducing the delta of percentage of fat mass (%; -5.60 ± 1.59 vs. -4.33 ± 1.5; P obese women undergoing weight loss treatment promoting significant changes in inflexibility metabolic

    BACKGROUND Hypomagnesemia is associated with a disturbed glucose metabolism. Insulin hypo-secretion predicts diabetes in the general population and in transplant recipients. We aimed to assess whether magnesium improves insulin secretion and glycemic control after transplantation in prevalent hypomagnesemic kidney transplant recipients. MATERIAL AND METHODS We conducted an open-label, randomized, parallel-group study. Eligible participants were adults more than 4 months after kidney transplantation on tacrolimus with persisting serum magnesium concentrations food-frequency questionnaire. All analyses were done on an intention-to-treat basis. RESULTS Magnesium with a mean daily dose of 688±237mg in the treatment group failed to lead to significant differences between the 2 groups in FPIR, fasting glucose, HbA1c, or HOMA-IR. Persisting hypomagnesemia was very common and associated with more insulin hypo-secretion, glucose intolerance, and lower dietary magnesium intake (142±56 versus 202±90 mg; p=0.015) as compared to patients with a rise in serum magnesium over 6 months. CONCLUSIONS Magnesium supplementation does not improve insulin secretion in stable hypomagnesemic kidney transplant recipients on tacrolimus. Persisting hypomagnesemia is associated with impaired glucose tolerance, insulin hypo-secretion, and dietary factors.

    Insulin resistance, when combined with impaired insulin secretion, contributes to the development of type 2 diabetes. Insulin resistance is characterised by a decrease in insulin effect on glucose transport in muscle and adipose tIssue. Tyrosine phosphorylation of insulin receptor substrate 1 (IRS......-1) and its binding to phosphatidylinositol 3-kinase (PI 3-kinase) are critical events in the insulin signalling cascade leading to insulin-stimulated glucose transport. Modification of IRS-1 by serine phosphorylation could be one of the mechanisms leading to a decrease in IRS-1 tyrosine...... to phosphorylate these serine residues have been identified. These exciting results suggest that serine phosphorylation of IRS-1 is a possible hallmark of insulin resistance in biologically insulin responsive cells or tIssues.

    Basal insulin peglispro (BIL) is a novel, PEGylated insulin lispro that has a large hydrodynamic size compared with insulin lispro. It has a prolonged duration of action, which is related to a delay in insulin absorption and a reduction in clearance. Given the different physical properties of BIL compared with native insulin and insulin lispro, it is important to assess the cellular internalization characteristics of the molecule. Using immunofluorescent confocal imaging, we compared the cellular internalization and localization patterns of BIL, biosynthetic human insulin, and insulin lispro. We assessed the effects of BIL on internalization of the insulin receptor (IR) and studied cellular clearance of BIL. Co-localization studies using antibodies to either insulin or PEG, and the early endosomal marker EEA1 showed that the overall internalization and subcellular localization pattern of BIL was similar to that of human insulin and insulin lispro; all were rapidly internalized and co-localized with EEA1. During ligand washout for 4 h, concomitant loss of insulin, PEG methoxy group, and PEG backbone immunostaining was observed for BIL, similar to the loss of insulin immunostaining observed for insulin lispro and human insulin. Co-localization studies using an antibody to the lysosomal marker LAMP1 did not reveal evidence of lysosomal localization for insulin lispro, human insulin, BIL, or PEG using either insulin or PEG immunostaining reagents. BIL and human insulin both induced rapid phosphorylation and internalization of human IR. Our findings show that treatment of cells with BIL stimulates internalization and localization of IR to early endosomes. Both the insulin and PEG moieties of BIL undergo a dynamic cellular process of rapid internalization and transport to early endosomes followed by loss of cellular immunostaining in a manner similar to that of insulin lispro and human insulin. The rate of clearance for the insulin lispro portion of BIL was slower than

    Full Text Available Venlafaxine (VLX, a serotonine-noradrenaline reuptake inhibitor, is one of the most commonly used antidepressant drugs in clinical practice for the treatment of major depressive disorder (MDD. Despite being more potent than its predecessors, similarly to them, the therapeutical effect of VLX is visible only 3-4 weeks after the beginning of treatment. Furthermore, recent papers show that antidepressants, including also VLX, enhance the motor recovery after stroke even in non depressed persons. In the present, transcriptomic-based study we looked for changes in gene expressions after a long-term VLX administration.Osmotic minipumps were implanted subcutaneously into Dark Agouti rats providing a continuous (40 mg/kg/day VLX delivery for three weeks. Frontal regions of the cerebral cortex were isolated and analyzed using Illumina bead arrays to detect genes showing significant chances in expression. Gene set enrichment analysis was performed to identify specific regulatory networks significantly affected by long term VLX treatment.Chronic VLX administration may have an effect on neurotransmitter release via the regulation of genes involved in vesicular exocytosis and receptor endocytosis (such as Kif proteins, Myo5a, Sv2b, Syn2 or Synj2. Simultaneously, VLX activated the expression of genes involved in neurotrophic signaling (Ntrk2, Ntrk3, glutamatergic transmission (Gria3, Grin2b and Grin2a, neuroplasticity (Camk2g/b, Cd47, synaptogenesis (Epha5a, Gad2 and cognitive processes (Clstn2. Interestingly, VLX increased the expression of genes involved in mitochondrial antioxidant activity (Bcl2 and Prdx1. Additionally, VLX administration also modulated genes related to insulin signaling pathway (Negr1, Ppp3r1, Slc2a4 and Enpp1, a mechanism that has recently been linked to neuroprotection, learning and memory.Our results strongly suggest that chronic VLX treatment improves functional reorganization and brain plasticity by influencing gene expression in

    the resonating sound from the microbubbles in the systemic circulation were recorded for determination of microvascular recruitment in designated muscle segments. Results showed that microvascular recruitment increased with insulin stimulation by ~30% in rats and ~40% in humans (study I). Furthermore......, it was observed that muscle contractions increased muscle perfusion rapidly by 3-4 fold and by 1-2 fold compared to basal and insulin, respectively, in both rat and human skeletal muscle (study I). The real-time contrast-enhanced ultrasound method was applied to investigate the vaso-active effect of the incretin...... hormone glucagon-like-peptide-1 (GLP-1) in the microcirculation. Glucagon-like-peptide-1 analogs are drugs used for treatments of insulin resistance and type 2 diabetes but the vascular effects of GLP-1 in vivo are elusive. Here it was shown that GLP-1 rapidly increased the microvascular recruitment...

    Objectives. The primary objective of this study was to assess the rules governing secondary school pupils' carriage of inhalers for emergency treatment of asthma in the North East of England. Design. This study was based upon a postal questionnaire survey. Setting. The setting for this study was mainstream free-to-attend secondary schools which admit 16 year old pupils within the 12 Local Authority areas which make up the North East of England. Participants. All 153 schools meeting the inclusion criteria were invited to participate in the study, of which 106 (69%) took part. Main Outcome Measures. Our three main outcome measures were: whether pupils are permitted to carry inhalers on their person while at school; whether advance permission is required for pupils to carry inhalers, and from whom; and whether the school has an emergency 'standby' salbutamol inhaler for use in asthma emergencies, as permitted since October 2014 under recent amendments to The Human Medicines Regulations 2012. Results. Of 98 schools submitting valid responses to the question, 99% (n = 97) permitted pupils to carry inhalers on their person while at school; the remaining school stored pupils' inhalers in a central location within the school. A total of 22% of included schools (n = 22) required parental permission before pupils were permitted to carry inhalers. Of 102 schools submitting valid responses to the question, 44% (n = 45) had purchased a 'standby' salbutamol inhaler for use in asthma emergencies. Conclusions. Most secondary schools in North East England permit pupils to carry inhalers on their person. The requirement in a minority of schools for parental permission to be given possibly contravenes the standard ethical practices in clinical medicine for children of this age. Only a minority of schools hold a 'standby' salbutamol inhaler for use in asthma emergencies. Wider availability may improve outcomes for asthma emergencies occurring in schools.

    synthesis was at least equally strong. Moreover, we found a correlation between plasma adiponectin and insulin activation of GS. This result is supported by a number of recent studies of animal models and muscle cell lines, which have shown that adiponectin augments insulin action on enzymes in the insulin signaling cascade. In contrast, we observed no differences in the abundance or activity of AMPK in obesity, type 2 diabetes, PCOS or inherited insulin resistance. This indicates that reduced insulin sensitivity in these conditions is not mediated via abnormal AMPK activity. The results from these studies demonstrate that the well-established abnormalities in insulin action on glucose uptake and glycogen synthesis are reflected by defects in insulin signaling to these cellular processes in type 2 diabetes, obesity, and PCOS, and as expected also in inherited insulin resistance caused by a mutation in INSR. In common metabolic disorders, low plasma adiponectin may contribute to insulin resistance and defects in insulin signaling, whereas in inherited insulin resistance a normal plasma adiponectin and reduced insulin clearance could contribute to maintain a sufficient activation of the insulin signaling cascade. The insight gained from these studies have improved our understanding of the molecular mechanisms underlying insulin resistance in skeletal muscle of humans, and can form the basis for further studies, which can lead to the development of treatment that more directly targets insulin resistance, and hence reduce the risk of type 2 diabetes and cardiovascular disease.

    An oral delivery system for insulin was developed and functional activity was tested in a non-obese diabetic (NOD) mice model. Calcium phosphate particles containing insulin was synthesized in the presence of PEG-3350 and modified by aggregating the particles with caseins to obtain the calcium phosphate-PEG-insulin-casein (CAPIC) oral insulin delivery system. Single doses of CAPIC formulation were tested in NOD mice under fasting or fed conditions to evaluate the glycemic activity. The blood glucose levels were monitored every 1-2h for 12h following the treatments using an ACCU CHECK blood glucose monitoring system. Orally administered and subcutaneously injected free insulin solution served as controls in the study. Based on the results obtained we propose that: (1). the biological activity of insulin is preserved in CAPIC formulation; (2). insulin in CAPIC formulations, but not the free insulin, displays a prolonged hypoglycemic effect after oral administration to diabetic mice; (3). CAPIC formulation protects insulin from degradation while passing through the acidic environment of the GI track until it is released in the less acidic environment of the intestines where it can be absorbed in its biologically active form; (4). CAPIC formulation represents a new and unique oral delivery system for insulin and other macromolecules.

    The aim of this study was to investigate the influence of association state and net charge of human insulin analogues on the rate of iontophoretic transport across hairless mouse skin, and the effect of different skin pretreatments on said transport. No insulin flux was observed with anodal delivery probably because of degradation at the Ag/AgCl anode. The flux during cathodal iontophoresis through intact skin was insignificant for human hexameric insulin, and only low and variable fluxes were observed for monomeric insulins. Using stripped skin on the other hand, the fluxes of monomeric insulins with two extra negative charges were 50-100 times higher than that of hexameric human insulin. Introducing three additional charges led to a further 2-3-fold increase in flux. Wiping the skin gently with absolute alcohol prior to iontophoresis resulted in a 1000-fold increase in transdermal transport of insulin relative to that across untreated skin, i.e. to almost the same level as stripping the skin. The alcohol pretreatment reduced the electrical resistance of the skin, presumably by lipid extraction. In conclusion, monomeric insulin analogues with at least two extra negative charges can be iontophoretically delivered across hairless mouse skin, whereas insignificant flux is observed with human, hexameric insulin. Wiping the skin with absolute alcohol prior to iontophoresis gave substantially improved transdermal transport of monomeric insulins resulting in clinically relevant delivery rates for basal treatment.

    Full Text Available Abstract Background This study was designed to develop a diabetes-specific questionnaire on parents' quality of life and satisfaction with their child's diabetes treatment, the WEll-being and Satisfaction of CAREgivers of Children with Diabetes Questionnaire, and to conduct psychometric validation of the WE-CARE. Methods Parents of 116 children aged 6 to 11 years were enrolled in the United States. Children had type 1 diabetes mellitus for > 1 year, had been treated with subcutaneous insulin for ≥ 2 months, and had a recent glycosylated hemoglobin (HbA1C measurement. Recruiting clinicians provided clinical information on the children. Over a two-week period, parents completed WE-CARE (initial 68 items and two other questionnaires (the 36-item Short Form of the Medical Outcomes Study and the 50-item Child Health Questionnaire-Parent Form twice. Results A literature review and one-on-one interview with caregivers and pediatricians led to the development of a draft questionnaire consisting of 68 items. Factor analysis suggested retention of 37 of the 68 initial items grouped into four multi-item scales (Psychosocial Well-being, Ease of Insulin Use, Treatment Satisfaction, and Acceptance of Insulin Administration as well as a Total Score. The four multi-item domains of WE-CARE were found to be psychometrically robust – they had negligible floor and ceiling effects, excellent internal consistency and test-retest reliability, high item-discriminant validity and good concurrent, divergent, known-group and clinical validity. Moderate interscale correlations among the four WE-CARE domains indicated that the concepts they measure were related but distinct. Conclusion These data suggest that WE-CARE provides a reliable and valid measure of parents' well-being and treatment satisfaction related to their child's diabetes. While these results show promise, additional validation of WE-CARE is warranted.

    A rare case of the insulin autoimmune syndrome (IAS) accompanied by insulin receptor anomaly is reported. Antibodies to insulin and insulin receptor were determined in the patient with severe hypoglycaemia before and after the treatment with prednisolone. Titers of antibody to insulin and insulin receptors were 73.0% and 41.5%, respectively. Drug-induced lymphocyte stimulation tests were all negative for the suspicious drugs. Her HLA-DR was DRB1*0403/04051. Following steroid therapy, the formation of antibodies was suppressed and alleviated her symptoms. Scatchard analysis yielded findings specific to polyclonal antibodies. The changes in autoantibodies resulted in alleviation of the hypoglycemic symptoms as a result of steroid therapy.

    Full Text Available Basal insulin represents an essential tool in the treatment of both type 1 and type 2 diabetes mellitus. The development of insulin analogues has improved the possibilities of diabetes treatment. Despite significant progress in understanding the physiology, chemistry, kinetics and action of insulin, currently available basal insulin products do not optimally mimic the endogenous profile of insulin. Although basal insulin analogues have some advantages over neutral protamine Hagedorn insulin in diabetes treatment, hypoglycaemia remains the main problem in the achievement of optimal glycaemic control in most patients with diabetes. These unmet clinical needs have stimulated the development of new basal insulin analogues with improved pharmacological profiles. This article reviews the specific characteristics of new long-acting insulin analogues to try and understand their benefits and limitations in the improvement of diabetes management and their possibilities in physiologic and safe insulin replacement.

    Full Text Available Scientific knowledge has advanced to enable the development of inhaled insulin. It is a form of diabetes medication administered via the pulmonary system that studies have shown to be efficacious in the treatment of both type 1 and type 2 diabetes. Inhaled insulin is a new, safe means to deliver insulin that may increase patient compliance with insulin therapy, helping them to achieve optimal glycemic control and possibly reducing their risk of developing cardiovascular complications. However, diabetes is a chronic illness requiring lifetime intervention. Empowering patients with the knowledge of the diabetes disease process may give them the confidence to be more autonomous in managing their diabetes. HIIP gives nurse practitioners a new option that may improve their patients’ acceptance of insulin therapy, and improve glycemic control.

    Increased skeletal muscle capillarization is associated with improved glucose tolerance and insulin sensitivity. However, a possible causal relationship has not previously been identified. We therefore investigated whether increased skeletal muscle capillarization increases insulin sensitivity....... Skeletal muscle specific angiogenesis was induced by adding the α1-adrenergic receptor antagonist Prazosin to the drinking water of Sprague Dawley rats (n=33) while 34 rats served as controls. Insulin sensitivity was measured ≥40 h after termination of the 3-week Prazosin treatment, which ensured...... that Prazosin was cleared from the blood stream. Whole-body insulin sensitivity was measured in conscious, unrestrained rats by hyperinsulinemic euglycemic clamp. Tissue specific insulin sensitivity was assessed by administration of 2-deoxy-[(3)H]-Glucose during the plateau phase of the clamp. Whole...

    To institute intensive insulin therapy protocol in an acute pediatric burn unit and study the mechanisms underlying its benefits. Prospective, randomized study. An acute pediatric burn unit in a tertiary teaching hospital. Children, 4-18 yrs old, with total body surface area burned > or =40% and who arrived within 1 wk after injury were enrolled in the study. Patients were randomized to one of two groups. Intensive insulin therapy maintained blood glucose levels between 80 and 110 mg/dL. Conventional insulin therapy maintained blood glucose patients were included in the data analysis consisting of resting energy expenditure, whole body and liver insulin sensitivity, and skeletal muscle mitochondrial function. Studies were performed at 7 days postburn (pretreatment) and at 21 days postburn (posttreatment). Resting energy expenditure significantly increased posttreatment (1476 +/- 124 to 1925 +/- 291 kcal/m(2) x day; p = .02) in conventional insulin therapy as compared with a decline in intensive insulin therapy. Glucose infusion rate was identical between groups before treatment (6.0 +/- 0.8 conventional insulin therapy vs. 6.8 +/- 0.9 mg/kg x min intensive insulin therapy; p = .5). Intensive insulin therapy displayed a significantly higher glucose clamp infusion rate posttreatment (9.1 +/- 1.3 intensive insulin therapy versus 4.8 +/- 0.6 mg/kg x min conventional insulin therapy, p = .005). Suppression of hepatic glucose release was significantly greater in the intensive insulin therapy after treatment compared with conventional insulin therapy (5.0 +/- 0.9 vs. 2.5 +/- 0.6 mg/kg x min; intensive insulin therapy vs. conventional insulin therapy; p = .03). States 3 and 4 mitochondrial oxidation of palmitate significantly improved in intensive insulin therapy (0.9 +/- 0.1 to 1.7 +/- 0.1 microm O(2)/CS/mg protein/min for state 3, p = .004; and 0.7 +/- 0.1 to 1.3 +/- 0.1 microm O(2)/CS/mg protein/min for state 4, p protocol improves insulin sensitivity and mitochondrial

    Graphical abstract: - Highlights: • Quercetin inhibits insulin ligand–receptor interactions. • Quercetin reduces downstream insulin receptor signaling. • Quercetin blocks insulin induced glucose uptake. • Quercetin suppresses insulin stimulated cancer cell proliferation and tumor growth. - Abstract: Although the flavonoid quercetin is known to inhibit activation of insulin receptor signaling, the inhibitory mechanism is largely unknown. In this study, we demonstrate that quercetin suppresses insulin induced dimerization of the insulin receptor (IR) through interfering with ligand–receptor interactions, which reduces the phosphorylation of IR and Akt. This inhibitory effect further inhibits insulin stimulated glucose uptake due to decreased cell membrane translocation of glucose transporter 4 (GLUT4), resulting in impaired cancer cell proliferation. The effect of quercetin in inhibiting tumor growth was also evident in an in vivo model, indicating a potential future application for quercetin in the treatment of cancers.

    Graphical abstract: - Highlights: • Quercetin inhibits insulin ligand–receptor interactions. • Quercetin reduces downstream insulin receptor signaling. • Quercetin blocks insulin induced glucose uptake. • Quercetin suppresses insulin stimulated cancer cell proliferation and tumor growth. - Abstract: Although the flavonoid quercetin is known to inhibit activation of insulin receptor signaling, the inhibitory mechanism is largely unknown. In this study, we demonstrate that quercetin suppresses insulin induced dimerization of the insulin receptor (IR) through interfering with ligand–receptor interactions, which reduces the phosphorylation of IR and Akt. This inhibitory effect further inhibits insulin stimulated glucose uptake due to decreased cell membrane translocation of glucose transporter 4 (GLUT4), resulting in impaired cancer cell proliferation. The effect of quercetin in inhibiting tumor growth was also evident in an in vivo model, indicating a potential future application for quercetin in the treatment of cancers

    PCOS, a heterogeneous disorder characterized by cystic ovarian morphology, androgen excess, and/or irregular periods, emerges during or shortly after puberty. Peri- and post-pubertal obesity, insulin resistance and consequent hyperinsulinemia are highly prevalent co-morbidities of PCOS and promote an ongoing state of excess androgen. Given the relationship of insulin to androgen excess, reduction of insulin secretion and/or improvement of its action at target tissues offer the possibility of improving the physical stigmata of androgen excess by correction of the reproductive dysfunction and preventing metabolic derangements from becoming entrenched. While lifestyle changes that concentrate on behavioral, dietary and exercise regimens should be considered as first line therapy for weight reduction and normalization of insulin levels in adolescents with PCOS, several therapeutic options are available and in wide use, including oral contraceptives, metformin, thiazolidenediones and spironolactone. Overwhelmingly, the data on the safety and efficacy of these medications derive from the adult PCOS literature. Despite the paucity of randomized control trials to adequately evaluate these modalities in adolescents, their use, particularly that of metformin, has gained popularity in the pediatric endocrine community. In this article, we present an overview of the use of insulin sensitizing medications in PCOS and review both the adult and (where available) adolescent literature, focusing specifically on the use of metformin in both mono- and combination therapy.

    This study aims to examine the operationalisation of 'psychological insulin resistance' (PIR) among people with type 2 diabetes and to identify and critique relevant measures. PIR has been operationalised as (1) the assessment of attitudes or beliefs about insulin therapy and (2) hypothetical or actual resistance, or unwillingness, to use to insulin. Five validated PIR questionnaires were identified. None was fully comprehensive of all aspects of PIR, and the rigour and reporting of questionnaire development and psychometric validation varied considerably between measures. Assessment of PIR should focus on the identification of negative and positive attitudes towards insulin use. Actual or hypothetical insulin refusal may be better conceptualised as a potential consequence of PIR, as its assessment overlooks the attitudes that may prevent insulin use. This paper provides guidance on the selection of questionnaires for clinical or research purpose and the development of new, or improvement of existing, questionnaires.

    Insulin is composed of 51 amino acids in two peptide chains (A and B) linked by two disulfide bonds. The three-dimensional structure of the insulin molecule (insulin monomer), essentially the same in solution and in solid phase, exists in two main conformations. These differ in the extent of helix in the B chain which is governed by the presence of phenol or its derivatives. In acid and neutral solutions, in concentrations relevant for pharmaceutical formulation, the insulin monomer assembles to dimers and at neutral pH, in the presence of zinc ions, further to hexamers. Many crystalline modifications of insulin have been identified but only those with the hexamer as the basic unit are utilized in preparations for therapy. The insulin hexamer forms a relatively stable unit but some flexibility remains within the individual molecules. The intrinsic flexibility at the ends of the B chain plays an important role in governing the physical and chemical stability of insulin. A variety of chemical changes of the primary structure (yielding insulin derivatives), and physical modifications of the secondary to quaternary structures (resulting in "denaturation," aggregation, and precipitation) are known to affect insulin and insulin preparations during storage and use (Fig. 8). The tendency of insulin to undergo structural transformation resulting in aggregation and formation of insoluble insulin fibrils has been one of the most intriguing and widely studied phenomena in relation to insulin stability. Although the exact mechanism of fibril formation is still obscure, it is now clear that the initial step is an exposure of certain hydrophobic residues, normally buried in the three-dimensional structure, to the surface of the insulin monomer. This requires displacement of the COOH-terminal B-chain residues from their normal position which can only be accomplished via monomerization of the insulin. Therefore, most methods stabilizing insulin against fibrillation share the

    Diabetes is a set of diseases characterized by defects in insulin utilization, either through autoimmune destruction of insulin-producing cells (Type I) or insulin resistance (Type II). Treatment options can include regular injections of insulin, which can be painful and inconvenient, often leading to low patient compliance. To overcome this problem, novel formulations of insulin are being investigated, such as inhaled aerosols. Sufficient deposition of powder in the peripheral lung to maximize systemic absorption requires precise control over particle size and density, with particles between 1 and 5 μm in aerodynamic diameter being within the respirable range. Insulin nanoparticles were produced by titrating insulin dissolved at low pH up to the pI of the native protein, and were then further processed into microparticles using solvent displacement. Particle size, crystallinity, dissolution properties, structural stability, and bulk powder density were characterized. We have demonstrated that pure drug insulin microparticles can be produced from nanosuspensions with minimal processing steps without excipients, and with suitable properties for deposition in the peripheral lung.

    To examine patient and physician beliefs regarding insulin therapy and the degree to which patients adhere to their insulin regimens. Internet survey of 1250 physicians (600 specialists, 650 primary care physicians) who treat patients with diabetes and telephone survey of 1530 insulin-treated patients (180 with Type 1 diabetes, 1350 with Type 2 diabetes) in China, France, Japan, Germany, Spain, Turkey, the UK or the USA. One third (33.2%) of patients reported insulin omission/non-adherence at least 1 day in the last month, with an average of 3.3 days. Three quarters (72.5%) of physicians report that their typical patient does not take their insulin as prescribed, with a mean of 4.3 days per month of basal insulin omission/non-adherence and 5.7 days per month of prandial insulin omission/non-adherence. Patients and providers indicated the same five most common reasons for insulin omission/non-adherence: too busy; travelling; skipped meals; stress/emotional problems; public embarrassment. Physicians reported low patient success at initiating insulin in a timely fashion and adjusting insulin doses. Most physicians report that many insulin-treated patients do not have adequate glucose control (87.6%) and that they would treat more aggressively if not for concern about hypoglycaemia (75.5%). Although a majority of patients (and physicians) regard insulin treatment as restrictive, more patients see insulin treatment as having positive than negative impacts on their lives. Glucose control is inadequate among insulin-treated patients, in part attributable to insulin omission/non-adherence and lack of dose adjustment. There is a need for insulin regimens that are less restrictive and burdensome with lower risk of hypoglycaemia. © 2012 The Authors. Diabetic Medicine © 2012 Diabetes UK.

    To compare foot length deficits between patients with Laron syndrome (LS) (primary growth hormone [GH] insensitivity) and congenital isolated GH deficiency (IGHD) and their response to replacement therapy with insulin-like growth factor-I (IGF-I) and hGH, respectively. Data for the study were collected from the records of nine children with LS (3 M, 6 F) 7.8 +/- 4.8 years old (mean +/- SD), and nine children with IGHD (3 M, 6 F), 3.8 +/- 3.3 years old. Fifteen non-treated adult patients with LS were also included in the study. Measurements of foot length were recorded without treatment and monitored during 9 years of treatment in the children and in the untreated adult patients. For statistical analysis the non-parametric Mann-Whitney U test was used. With almost similar basal values in growth deficit and pre-treatment growth velocities, the achievements towards norms after 9 years of treatment were greater in the patients with IGHD than in the patients with LS: foot length reached -1.4 +/- 0.8 vs. -3.3 +/- 1.0 SDS (mean +/- SD), and body height -2.2 +/- 1.0 vs. -3.9 +/- 0.5 SDS. The difference between the two groups could be due to the initiation of replacement therapy in the patients with IGHD at a younger age. Adult foot size of untreated patients with LS is small but less retarded than the height deficit. Both IGF-I and hGH are potent growth stimulating hormones of linear growth and acrae as exemplified by foot growth.

    Previously, we reported that CARM1 undergoes ubiquitination-dependent degradation in renal podocytes. It was also reported that CARM1 is necessary for fasting-induced hepatic gluconeogenesis. Based on these reports, we hypothesized that treatment with insulin, a hormone typically present under the ‘fed’ condition, would inhibit gluconeogenesis via CARM1 degradation. HepG2 cells, AML-12 cells, and rat primary hepatocytes were treated with insulin to confirm CARM1 downregulation. Surprisingly, insulin treatment increased CARM1 expression in all cell types examined. Furthermore, treatment with insulin increased histone 3 methylation at arginine 17 and 26 in HepG2 cells. To elucidate the role of insulin-induced CARM1 upregulation, the HA-CARM1 plasmid was transfected into HepG2 cells. CARM1 overexpression did not increase the expression of lipogenic proteins generally increased by insulin signaling. Moreover, CARM1 knockdown did not influence insulin sensitivity. Insulin is known to facilitate hepatic proliferation. Like insulin, CARM1 overexpression increased CDK2 and CDK4 expression. In addition, CARM1 knockdown reduced the number of insulin-induced G2/M phase cells. Moreover, GFP-CARM1 overexpression increased the number of G2/M phase cells. Based on these results, we concluded that insulin-induced CARM1 upregulation facilitates hepatocyte proliferation. These observations indicate that CARM1 plays an important role in liver pathophysiology. - Highlights: • Insulin treatment increases CARM1 expression in hepatocytes. • CARM1 overexpression does not increase the expression of lipogenic proteins. • CARM1 knockdown does not influence insulin sensitivity. • Insulin-induced CARM1 upregulation facilitates hepatocyte proliferation.

Despite substantial literature to support the benefits of glucose lowering and clear treatment targets, glycemic control remains suboptimal for most people with DM in the United States. Pharmacokinetic limitations of conventional insulins have been a barrier to achieving treatment targets secondary to adverse effects such as hypoglycemia and weight gain. Recombinant DNA technology has allowed modification of the insulin molecule to produce insulin analogues that overcome these pharmacokinetic limitations. With time action profiles that more closely mimic physiologic insulin secretion, rapid acting insulin analogues (RAAs reduce post-prandial glucose excursions and hypoglycemia when compared to regular human insulin (RHI. Insulin glulisine (Apidra® is a rapid-acting insulin analogue created by substituting lysine for asparagine at position B3 and glutamic acid for lysine at position B29 on the B chain of human insulin. The quick absorption of insulin glulisine more closely reproduces physiologic first-phase insulin secretion and its rapid acting profile is maintained across patient subtypes. Clinical trials have demonstrated comparable or greater efficacy of insulin glulisine versus insulin lispro or RHI, respectively. Efficacy is maintained even when insulin glulisine is administered post-meal. In addition, glulisine appears to have a more rapid time action profile compared with insulin lispro across various body mass indexes (BMIs. The safety and tolerability profile of insulin glulisine is also comparable to that of insulin

    1997-05-01

    Formation of insulin fibrils is a physical process by which partially unfolded insulin molecules interact with each other to form linear aggregates. Shielding of hydrophobic domains is the main driving force for this process, but formation of intermolecular beta-sheet may further stabilize the fibrillar structure. Conformational displacement of the B-chain C-terminal with exposure of nonpolar, aliphatic core residues, including A2, A3, B11, and B15, plays a crucial role in the fibrillation process. Recent crystal analyses and molecular modeling studies have suggested that when insulin fibrillates this exposed domain interacts with a hydrophobic surface domain formed by the aliphatic residues A13, B6, B14, B17, and B18, normally buried when three insulin dimers form a hexamer. In rabbit immunization experiments, insulin fibrils did not elicit an increased immune response with respect to formation of IgG insulin antibodies when compared with native insulin. In contrast, the IgE response increased with increasing content of insulin in fibrillar form. Strategies and practical approaches to prevent insulin from forming fibrils are reviewed. Stabilization of the insulin hexameric structure and blockage of hydrophobic interfaces by addition of surfactants are the most effective means of counteracting insulin fibrillation.

    Full Text Available OBJECTIVE: Insulin is recommended as an appropriate treatment in type 2 diabetes patients with suboptimal glycemic control; however, its initiation is often delayed. We therefore conducted the DAWN (Diabetes Attitudes, Wishes and Needs JAPAN study in an attempt to identify specific patient- and physician-related factors which contribute to delay of insulin initiation among Japanese patients with diabetes. In this report, we explored barriers for physicians which prevent timely insulin initiation. METHODS: The DAWN JAPAN study is a multicenter, questionnaire-based survey, conducted between 2004 and 2005. Participating physicians were categorized as follows based on their expertise: Japan Diabetes Society (JDS certified specialists (n = 77, JDS-affiliated physicians (n = 30, and non-JDS-affiliated physicians (n = 27. To assess physician barriers to insulin initiation, we have used a newly developed 27- item questionnaire. RESULTS: The mean age of patients (n = 11,656 treated by participating physicians was 64.1 years. The mean duration of diabetes was 121.6 months, and their mean HbA1c was 7.5%. Insulin was used in 27.4% of total patients. With regard to physician barriers to insulin initiation, the biggest differences in concerns expressed by JDS-certified specialists and non-JDS-affiliated physicians were observed in the following items with statistical significance: "I do not have staff (nurse, pharmacists who can assist with explanations" (1.3% vs 55.5%, respectively, "I have concerns about the use of insulin therapy in elderly patients" (38.1% vs 81.5%, and "It is difficult to provide guidance and education on insulin injection to patients" (16.9% vs 55.5%. The mean HbA1c at which physicians responded they would recommend insulin to their patients was 8.7%; however, they would reduce this level to 8.2% if they themselves required insulin.

    Although the brain has long been considered an insulin-independent organ, recent research has shown that insulin has significant effects on the brain, where it plays a role in maintaining glucose and energy homeostasis. To avoid peripheral insulin resistance, the brain may act via hypoinsulinemic responses, maintaining glucose metabolism and insulin sensitivity within its own confines; however, brain insulin resistance may develop due to environmental factors. Insulin has two important functions in the brain: controlling food intake and regulating cognitive functions, particularly memory. Notably, defects in insulin signaling in the brain may contribute to neurodegenerative disorders. Insulin resistance may damage the cognitive system and lead to dementia states. Furthermore, inflammatory processes in the hypothalamus, where insulin receptors are expressed at high density, impair local signaling systems and cause glucose and energy metabolism disorders. Excessive caloric intake and high-fat diets initiate insulin and leptin resistance by inducing mitochondrial dysfunction and endoplasmic reticulum stress in the hypothalamus. This may lead to obesity and diabetes mellitus (DM). Exercise can enhance brain and hypothalamic insulin sensitivity, but it is the option least preferred and/or continuously practiced by the general population. Pharmacological treatments that increase brain and hypothalamic insulin sensitivity may provide new insights into the prevention of dementia disorders, obesity, and type 2 DM in the future.

  11. A Molecular and Whole Body Insight of the Mechanisms Surrounding Glucose Disposal and Insulin Resistance with Hypoxic Treatment in Skeletal Muscle

    2016-01-01

    Full Text Available Although the mechanisms are largely unidentified, the chronic or intermittent hypoxic patterns occurring with respiratory diseases, such as chronic pulmonary disease or obstructive sleep apnea (OSA and obesity, are commonly associated with glucose intolerance. Indeed, hypoxia has been widely implicated in the development of insulin resistance either via the direct action on insulin receptor substrate (IRS and protein kinase B (PKB/Akt or indirectly through adipose tissue expansion and systemic inflammation. Yet hypoxia is also known to encourage glucose transport using insulin-dependent mechanisms, largely reliant on the metabolic master switch, 5′ AMP-activated protein kinase (AMPK. In addition, hypoxic exposure has been shown to improve glucose control in type 2 diabetics. The literature surrounding hypoxia-induced changes to glycemic control appears to be confusing and conflicting. How is it that the same stress can seemingly cause insulin resistance while increasing glucose uptake? There is little doubt that acute hypoxia increases glucose metabolism in skeletal muscle and does so using the same pathway as muscle contraction. The purpose of this review paper is to provide an insight into the mechanisms underpinning the observed effects and to open up discussions around the conflicting data surrounding hypoxia and glucose control.

    We have evaluated the effect of peripheral insulin deficiency on brain insulin pathway activity in a mouse model of type 1 diabetes, the parallels with Alzheimer's disease (AD), and the effect of treatment with insulin. Nine weeks of insulin-deficient diabetes significantly impaired the learning capacity of mice, significantly reduced insulin-degrading enzyme protein expression, and significantly reduced phosphorylation of the insulin-receptor and AKT. Phosphorylation of glycogen synthase kinase-3 (GSK3) was also significantly decreased, indicating increased GSK3 activity. This evidence of reduced insulin signaling was associated with a concomitant increase in tau phosphorylation and amyloid beta protein levels. Changes in phosphorylation levels of insulin receptor, GSK3, and tau were not observed in the brain of db/db mice, a model of type 2 diabetes, after a similar duration (8 weeks) of diabetes. Treatment with insulin from onset of diabetes partially restored the phosphorylation of insulin receptor and of GSK3, partially reduced the level of phosphorylated tau in the brain, and partially improved learning ability in insulin-deficient diabetic mice. Our data indicate that mice with systemic insulin deficiency display evidence of reduced insulin signaling pathway activity in the brain that is associated with biochemical and behavioral features of AD and that it can be corrected by insulin treatment.

    Interleukin-1β (IL-1β) promotes insulin resistance in tissues such as liver and skeletal muscle; however the influence of IL-1β on placental insulin signaling is unknown. We recently reported increased IL-1β protein expression in placentas of obese mothers, which could contribute to insulin resistance. In this study, we tested the hypothesis that IL-1β inhibits insulin signaling and prevents insulin-stimulated amino acid transport in cultured primary human trophoblast (PHT) cells. Cultured trophoblasts isolated from term placentas were treated with physiological concentrations of IL-1β (10pg/ml) for 24h. IL-1β increased the phosphorylation of insulin receptor substrate-1 (IRS-1) at Ser307 (inhibitory) and decreased total IRS-1 protein abundance but did not affect insulin receptor β expression. Furthermore, IL-1β inhibited insulin-stimulated phosphorylation of IRS-1 (Tyr612, activation site) and Akt (Thr308) and prevented insulin-stimulated increase in PI3K/p85 and Grb2 protein expression. IL-1β alone stimulated cRaf (Ser338), MEK (Ser221) and Erk1/2 (Thr202/Tyr204) phosphorylation. The inflammatory pathways nuclear factor kappa B and c-Jun N-terminal kinase, which are involved in insulin resistance, were also activated by IL-1β treatment. Moreover, IL-1β inhibited insulin-stimulated System A, but not System L amino acid uptake, indicating functional impairment of insulin signaling. In conclusion, IL-1β inhibited the insulin signaling pathway by inhibiting IRS-1 signaling and prevented insulin-stimulated System A transport, thereby promoting insulin resistance in cultured PHT cells. These findings indicate that conditions which lead to increased systemic maternal or placental IL-1β levels may attenuate the effects of maternal insulin on placental function and consequently fetal growth.

    Patients with Type 2 diabetes mellitus (T2DM) are often treated with multiple glucose-lowering and cardiovascular agents. The concomitant use of nitrates, renin-angiotensin system (RAS) blockers, or insulin has been linked to a potential increase in myocardial ischemic risk with rosiglitazone. The PROactive database provides an opportunity to investigate the effects of these medications on the potential macrovascular benefits reported with pioglitazone. The PROactive study was a randomized double-blind prospective trial that evaluated mortality and cardiovascular morbidity in 5238 patients with T2DM and macrovascular disease. Patients received pioglitazone or placebo in addition to their baseline glucose-lowering and cardiovascular medications. The effect of pioglitazone on composite endpoints was evaluated, including all-cause death, myocardial infarction (MI), and stroke, as well as safety events of edema and serious heart failure, in subgroups using nitrates, RAS blockers, or insulin at baseline. The risk of all-cause death, MI, and stroke for pioglitazone versus placebo was similar regardless of the baseline use of nitrates, RAS blockers, or insulin, with hazard ratios ranging from 0.81 to 0.87. Similar results were obtained for the other composite endpoints analyzed. There were no significant interactions between baseline medication subgroups and treatment. The increased risk of edema and serious heart failure was consistent across the baseline medication subgroups. This post hoc analysis did not reveal an increased risk of macrovascular events with pioglitazone in patients receiving nitrates, RAS blockers, or insulin. Rather, all patients realized the same trend towards benefit with pioglitazone, and adverse events of edema and heart failure were predictable. © 2010 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Blackwell Publishing Asia Pty Ltd.

    Full Text Available To determine effect of acupuncture on insulin resistance in Otsuka Long-Evans Tokushima Fatty (OLETF rats and to evaluate expression of insulin signaling components. Rats were divided into three groups: Sprague-Dawley (SD rats, OLETF rats, and acupuncture+OLETF rats. Acupuncture was subcutaneously applied to Neiguan (PC6, Zusanli (ST36, and Sanyinjiao (SP6; in contrast, acupuncture to Shenshu (BL23 was administered perpendicularly. For Neiguan (PC6 and Zusanli (ST36, needles were connected to an electroacupuncture (EA apparatus. Fasting blood glucose (FPG was measured by glucose oxidase method. Plasma fasting insulin (FINS and serum C peptide (C-P were determined by ELISA. Protein and mRNA expressions of insulin signaling molecules were determined by Western blot and real-time RT-PCR, respectively. OLETF rats exhibit increased levels of FPG, FINS, C-P, and homeostasis model assessment-estimated insulin resistance (HOMA-IR, which were effectively decreased by acupuncture treatment. mRNA expressions of several insulin signaling related molecules IRS1, IRS2, Akt2, aPKCζ, and GLUT4 were decreased in OLETF rats compared to SD controls. Expression of these molecules was restored back to normal levels upon acupuncture administration. PI3K-p85α was increased in OLETF rats; this increase was also reversed by acupuncture treatment. Acupuncture improves insulin resistance in OLETF rats, possibly via regulating expression of key insulin signaling related molecules.

    Background: The A1chieve, a multicentric (28 countries), 24-week, non-interventional study evaluated the safety and effectiveness of insulin detemir, biphasic insulin aspart and insulin aspart in people with T2DM (n = 66,726) in routine clinical care across four continents. Materials and Methods: Data was collected at baseline, at 12 weeks and at 24 weeks. This short communication presents the results for patients enrolled from Northern Tunisia. Results: A total of 443 patients were enrolled in the study. Four different insulin analogue regimens were used in the study. Study patients had started on or were switched to biphasic insulin aspart (n = 137), insulin detemir (n = 243), insulin aspart (n = 11), basal insulin plus insulin aspart (n = 39) and other insulin combinations (n = 13). At baseline glycaemic control was poor for both insulin naïve (mean HbA1c: 10.2%) and insulin user (mean HbA1c: 9.8%) groups. After 24 weeks of treatment, both the study groups showed improvement in HbA1c (insulin naïve: −2.1%, insulin users: −0.9%). SADRs including major hypoglycaemic events or episodes did not occur in any of the study patients. Conclusion: Starting or switching to insulin analogues was associated with improvement in glycaemic control with a low rate of hypoglycaemia. PMID:24404473

    2013-07-01

    Glucose is the molecule that drives milk production, and insulin plays a pivotal role in the glucose metabolism of dairy cows. The effect of insulin on the glucose metabolism is regulated by the secretion of insulin by the pancreas and the insulin sensitivity of the skeletal muscles, the adipose tissue, and the liver. Insulin resistance may develop as part of physiologic (pregnancy and lactation) and pathologic processes, which may manifest as decreased insulin sensitivity or decreased insulin responsiveness. A good knowledge of the normal physiology of insulin is needed to measure the in vivo insulin resistance of dairy cows. Copyright © 2013 Elsevier Inc. All rights reserved.

  4. Flexibility in insulin prescription

    2016-01-01

    Full Text Available This communication explores the concept of flexibility, a propos insulin preparations and insulin regimes used in the management of type 2 diabetes. The flexibility of an insulin regime or preparation is defined as their ability to be injected at variable times, with variable injection-meal time gaps, in a dose frequency and quantum determined by shared decision making, with a minimal requirement of glucose monitoring and health professional consultation, with no compromise on safety, efficiency and tolerability. The relative flexibility of various basal, prandial and dual action insulins, as well as intensive regimes, is compared. The biopsychosocial model of health is used to assess the utility of different insulins while encouraging a philosophy of flexible insulin usage.

    2014-03-01

    Degludec is the most recent molecule of the ultra-long-acting basal insulin analogues approved for human use. It forms soluble multihexamers which after subcutaneous injection are converted into monomers, and are thus slowly and continuously absorbed into the bloodstream. This absorption mechanism confers degludec an ultra-long and stable action profile, with no concentration peaks. This paper discusses the most recent studies in patients with type 1 and 2 diabetes mellitus, which showed degludec to be non inferior in decreasing HbA1c, ensuring optimum glycemic control similar to that achieved with insulin glargine or detemir. Degludec also had an improved safety profile, as it was associated to a significantly lower rate of nocturnal hypoglycemia in both types of diabetes and to a potentially lower overall hypoglycemia rate in type 2 DM. Degludec also opens the possibility to use more flexible regimens. Copyright © 2013 SEEN. Published by Elsevier Espana. All rights reserved.

  8. Induction of insulin secretion in engineered liver cells by nitric oxide

    Full Text Available Abstract Background Type 1 Diabetes Mellitus results from an autoimmune destruction of the pancreatic beta cells, which produce insulin. The lack of insulin leads to chronic hyperglycemia and secondary complications, such as cardiovascular disease. The currently approved clinical treatments for diabetes mellitus often fail to achieve sustained and optimal glycemic control. Therefore, there is a great interest in the development of surrogate beta cells as a treatment for type 1 diabetes. Normally, pancreatic beta cells produce and secrete insulin only in response to increased blood glucose levels. However in many cases, insulin secretion from non-beta cells engineered to produce insulin occurs in a glucose-independent manner. In the present study we engineered liver cells to produce and secrete insulin and insulin secretion can be stimulated via the nitric oxide pathway. Results Expression of either human insulin or the beta cell specific transcription factors PDX-1, NeuroD1 and MafA in the Hepa1-6 cell line or primary liver cells via adenoviral gene transfer, results in production and secretion of insulin. Although, the secretion of insulin is not significantly increased in response to high glucose, treatment of these engineered liver cells with L-arginine stimulates insulin secretion up to three-fold. This L-arginine-mediated insulin release is dependent on the production of nitric oxide. Conclusion Liver cells can be engineered to produce insulin and insulin secretion can be induced by treatment with L-arginine via the production of nitric oxide.

    Full Text Available It is unknown whether autophagy activity is altered in insulin resistant podocytes and whether autophagy could be a therapeutic target for diabetic nephropathy (DN. Here we used shRNA transfection to knockdown the insulin receptor (IR gene in cultured human immortalized podocytes as an in vitro insulin resistant model. Autophagy related proteins LC3, Beclin, and p62 as well as nephrin, a podocyte injury marker, were assessed using western blot and immunofluorescence staining. Our results show that autophagy is suppressed when podocytes lose insulin sensitivity
