Abstract
Disparities in type 2 diabetes (T2D) care is a global problem across diverse cultures. The Dysglycemia-Based Chronic Disease (DBCD) model promotes early and sustainable interventions along the insulin resistance (stage 1), prediabetes (stage 2), T2D (stage 3), and complications (stage 4) spectrum. In this model, lifestyle medicine is the cornerstone of preventive care to reduce DBCD progression and the socioeconomic/biological burden of disease. A comprehensive literature review, spanning 2000 to 2021, was performed and 55 studies were included examining the effects of lifestyle medicine and their cultural adaptions with different prevention modalities. In stage 1, primordial prevention targets modifiable primary drivers (behavior and environment), unhealthy lifestyles, abnormal adiposity, and insulin resistance with educational and motivational health promotion activities at individual, group, community, and population-based scales. Primary, secondary, and tertiary prevention targets individuals with mild hyperglycemia, severe hyperglycemia, and complications, respectively, using programs that incorporate structured lifestyle interventions. Culturally adapted lifestyle change in primary and secondary prevention improved quality of life and biomarkers, but with a limited impact of tertiary prevention on cardiovascular events. In conclusion, lifestyle medicine with cultural adaptations is an integral part of preventive care in patients with T2D. However, considerable research gaps exist, especially for tertiary prevention.

The effect of behaviour change interventions on changes in physical activity and anthropometrics in ambulatory hospital settings: a systematic review and meta-analysis.

[PMID: 33413512 PMCID: PMC7791684 DOI: 10.1186/s12966-020-01076-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Accepted: 12/14/2020] [Indexed: 01/17/2023] Open
Abstract
Background The aim of this systematic review and meta-analysis was to investigate whether behaviour change interventions promote changes in physical activity and anthropometrics (body mass, body mass index and waist circumference) in ambulatory hospital populations. Methods Randomised controlled trials were collected from five bibliographic databases (MEDLINE, Embase, CINAHL, The Cochrane Central Register of Controlled Trials (CENTRAL) and PsycINFO). Meta-analyses were conducted using change scores from baseline to determine mean differences (MD), standardised mean differences (SMD) and 95% confidence intervals (95% CI). The Grades of Recommendation, Assessment, Development and Evaluation approach was used to evaluate the quality of the evidence. Results A total of 29 studies met the eligibility criteria and 21 were included in meta-analyses. Behaviour change interventions significantly increased physical activity (SMD: 1.30; 95% CI: 0.53 to 2.07, p < 0.01), and resulted in significant reductions in body mass (MD: -2.74; 95% CI: − 4.42 to − 1.07, p < 0.01), body mass index (MD: -0.99; 95% CI: − 1.48 to − 0.50, p < 0.01) and waist circumference (MD: -2.21; 95% CI: − 4.01 to − 0.42, p = 0.02). The GRADE assessment indicated that the evidence is very uncertain about the effect of behaviour change interventions on changes in physical activity and anthropometrics in ambulatory hospital patients. Conclusions Behaviour change interventions initiated in the ambulatory hospital setting significantly increased physical activity and significantly reduced body mass, body mass index and waist circumference. Increased clarity in interventions definitions and assessments of treatment fidelity are factors that need attention in future research. PROSPERO registration number: CRD42020172140.

Abstract
BACKGROUND Most people with type 2 diabetes are overweight, so initial treatment is aimed at reducing weight and increasing physical activity. Even modest weight loss can improve control of blood glucose. If drug treatment is necessary, the drug of first choice is metformin. However, some people cannot tolerate metformin, which causes diarrhoea in about 10%, and it cannot be used in people with renal impairment. This review appraises three of the newest class of drugs for monotherapy when metformin cannot be used, the sodium-glucose co-transporter 2 (SGLT2) inhibitors. OBJECTIVE To review the clinical effectiveness and cost-effectiveness of dapagliflozin (Farxiga, Bristol-Myers Squibb, Luton, UK), canagliflozin (Invokana, Janssen, High Wycombe, UK) and empagliflozin (Jardiance, Merck & Co., Darmstadt, Germany), in monotherapy in people who cannot take metformin. SOURCES MEDLINE (1946 to February 2015) and EMBASE (1974 to February 2015) for randomised controlled trials lasting 24 weeks or more. For adverse events, a wider range of studies was used. Three manufacturers provided submissions. METHODS Systematic review and economic evaluation. A network meta-analysis was carried out involving the three SGLT2 inhibitors and key comparators. Critical appraisal of submissions from three manufacturers. RESULTS We included three trials of dapagliflozin and two each for canagliflozin and empagliflozin. The trials were of good quality. The canagliflozin and dapagliflozin trials compared them with placebo, but the two empagliflozin trials included active comparators. All three drugs were shown to be effective in improving glycaemic control, promoting weight loss and lowering blood pressure (BP). LIMITATIONS There were no head-to-head trials of the different flozins, and no long-term data on cardiovascular outcomes in this group of patients. Most trials were against placebo. The trials were done in patient groups that were not always comparable, for example in baseline glycated haemoglobin or body mass index. Data on elderly patients were lacking. CONCLUSIONS Dapagliflozin, canagliflozin and empagliflozin are effective in improving glycaemic control, with added benefits of some reductions in BP and weight. Adverse effects are urinary and genital tract infections in a small proportion of users. In monotherapy, the three drugs do not appear cost-effective compared with gliclazide or pioglitazone, but may be competitive against sitagliptin (Januvia, Boehringer Ingelheim, Bracknell, UK).

Abstract
Insulin therapy (IT) is initiated for patients with type 2 diabetes mellitus when glycaemic targets are not met with diet and other hypoglycaemic agents. The initiation of IT improves glycaemic control and reduces the risk of microvascular complications. There is, however, an associated weight gain following IT, which may adversely affect diabetic and cardiovascular morbidity and mortality. A 3 to 9 kg insulin-associated weight gain (IAWG) is reported to occur in the first year of initiating IT, predominantly caused by adipose tissue. The potential causes for this weight gain include an increase in energy intake linked to a fear of hypoglycaemia, a reduction in glycosuria, catch-up weight, and central effects on weight and appetite regulation. Patients with type 2 diabetes who are receiving IT often have multiple co-morbidities, including obesity, that are exacerbated by weight gain, making the management of their diabetes and obesity challenging. There are several treatment strategies for patients with type 2 diabetes, who require IT, that attenuate weight gain, help improve glycaemic control, and help promote body weight homeostasis. This review addresses the effects of insulin initiation and intensification on IAWG, and explores its potential underlying mechanisms, the predictors for this weight gain, and the available treatment options for managing and limiting weight gain.

Abstract
After bariatric surgery there are some favourable effects on comorbidities of obesity as glucose and lipid metabolism besides weight loss. Therefore surgical measures targeting at improvement of such metabolic disorders especially diabetes type 2 has been called "metabolic surgery". The complexity of its underlying metabolic mechanisms is not yet clear, but restriction of energy and weight loss (maintenance) seem to be the cornerstones.Risks of these procedures which are drawn of the established methods of bariatric surgery are reported to be relatively low in qualified centers. Being an elective operation special focus has to be set on mortality and morbidity, numbers of therapeutic failure and redo-surgery. Multiple irreversible and not seldom severe, potentially life-threatening consequences of bariatric surgery require consequent interdisciplinary postsurgery care and therapy throughout the whole life, especially substitution therapy of deficiencies due to post-operative malassimilation, if necessary. Little is known about long term consequences of modified anatomy and function of digestive system caused by surgery, and there may be a delay of (many) years until manifestation of clinical problems.Obese diabetics (BMI ≥ 35 kg/m2) should primarily be treated conservatively in an "individualized" way. Metabolic surgery should not be considered earlier than failure of the conservative approach has to be stated (in this case as an "ultima ratio" in well defined trials). A broader use of metabolic surgery beyond this narrow frame is not yet supported by long-term evidence-based data showing its value and safety.

Abstract
AIMS To provide a systematic review and meta-analysis of recent evidence on the effectiveness of lifestyle-based weight loss interventions for adults with type 2 diabetes. METHODS A search of the literature from January 2003 to July 2013 was conducted (PubMed, Embase, CINAHL and Web of Science). The studies considered eligible were randomized controlled trials evaluating weight loss interventions (diet and physical activity, with or without behavioural strategies) of ≥12 weeks duration, compared with usual care or another comparison intervention. Ten studies were included for review. Some heterogeneity was present in the sample, therefore, random-effects models were used to calculate pooled effects. RESULTS Intervention duration ranged from 16 weeks to 9 years, with all but one delivered via individual or group face-to-face sessions. From six studies comparing lifestyle intervention with usual care the pooled effect on weight (n = 5795) was -3.33 kg [95% confidence interval (CI) -5.06, -1.60 kg], and on glycated haemoglobin (HbA1c; n = 5784) was -0.29% (95% CI -0.61, 0.03%), with both attenuated in sensitivity analyses. The pooled within-group effect on weight (n = 3063) from all 10 lifestyle intervention groups was -5.33 kg (95% CI -7.33, -3.34 kg), also attenuated in sensitivity analyses. None of the participant or intervention characteristics examined explained the heterogeneity. Only one study assessed whether intervention effects were maintained after the end of the intervention. CONCLUSIONS Lifestyle-based weight loss intervention trials in type 2 diabetes achieve, on average, modest reductions in weight and HbA1c levels, but results were heavily influenced by one trial. Evidence-based approaches for improving the effectiveness of lifestyle-based interventions in type 2 diabetes are needed, along with future studies reporting on maintenance and cost-effectiveness.

Abstract
Lifestyle changes to healthy diet (HD) and habitual physical activity (HPA) are recommended in type 2 diabetes mellitus (T2DM). Yet, for most people with diabetes, it may be difficult to start changing. We investigated the stage of change toward healthier lifestyles according to Prochaska's model, and the associated psychological factors in T2DM patients, as a prerequisite to improve strategies to implement behavior changes in the population. A total of 1,353 consecutive outpatients with T2DM attending 14 tertiary centers for diabetes treatment completed the validated EMME-3 questionnaire, consisting of two parallel sets of instruments to define the stage of change for HD and HPA, respectively. Logistic regression was used to determine the factors associated with stages that may hinder behavioral changes. A stage of change favoring progress to healthier behaviors was more common in the area of HD than in HPA, with higher scores in action and maintenance. Differences were observed in relation to gender, age and duration of disease. After adjustment for confounders, resistance to change toward HD was associated with higher body mass index (BMI) (odds ratio (OR) 1.05; 95 % confidence interval (CI) 1.02-1.08). Resistance to improve HPA also increased with BMI (OR 1.06; 95 % CI 1.03-1.10) and decreased with education level (OR 0.74; 95 % CI 0.64-0.92). Changing lifestyle, particularly in the area of HPA, is not perceived as an essential part of treatment by many subjects with T2DM. This evidence must be considered when planning behavioral programs, and specific interventions are needed to promote adherence to HPA.

Abstract
BACKGROUND Despite high insulin doses, good glycaemic control is often lacking in type 2 diabetes patients and new therapeutic options are needed. METHODS In a proof of principle study, an energy-restricted, protein-rich meal replacement (PRMR) was examined as a means of reducing insulin requirement, HbA1C and body weight. Obese type 2 diabetes patients (n = 22) with >100 U insulin per day replaced, in week 1, the three main meals with 50 g of PRMR (Almased-Vitalkost) each (= 4903 kJ day(-1) ). In weeks 2-4, breakfast and dinner were replaced, and, in weeks 5-12, only dinner was replaced. Clinical parameters were determined at baseline, and after 4, 8 and 12 weeks, as well as after 1.5 years of follow-up. The Wilcoxon signed-rank test was used for the intention-to-treat analysis and the Mann-Whitney U-test for subgroup analyses. RESULTS The 12-week-programme was completed by 15 participants (68%). After 1 week, the mean insulin dose was reduced from 147 (75) U to 91 (55) U day(-1) (P = 0.0001), and to 65 (32) U (P < 0.0001) after 12 weeks of study. Over a period of 12 weeks, HbA1c decreased from 8.8% (1.4%) to 8.1% (1.6%) (P = 0.048) and weight decreased from 118.0 (19.7) kg to 107.4 (19.2) kg (P < 0.0001). Moreover, body mass index, waist and hip circumference, fasting blood glucose, triglycerides and high-density lipoprotein cholesterol improved significantly. After 1.5 years, insulin requirement and weight remained significantly lower than baseline. Participants who continued PRMR further reduced their HbA1c, weight and insulin dose. Two patients were able to stop insulin therapy altogether. CONCLUSIONS Energy-restricted PRMR was effective in reducing insulin requirement of type 2 diabetes patients with intensified insulin therapy accompanied by a reduction of HbA1c, weight and other cardiometabolic risk factors. With the continuous use of PRMR, glycaemic control might be improved in the long term.

Abstract
PURPOSE The aim of this study is to observe glycemic changes after emphasizing the importance of lifestyle modification in patients with mild or moderately uncontrolled type 2 diabetes. MATERIALS AND METHODS We examined 51 type 2 diabetic patients with 7.0-9.0% hemoglobin A1c (HbA1c) who preferred to change their lifestyle rather than followed the recommendation of medication change. At the enrollment, the study subjects completed questionnaires about diet and exercise. After 3 months, HbA1c levels were determined and questionnaires on the change of lifestyle were accomplished. We divided the study subjects into 3 groups: improved (more than 0.3% decrease of HbA1c), aggravated (more than 0.3% increase of HbA1c) and not changed (-0.3% <HbA1c change <0.3%). RESULTS Among the total 51 subjects, 18 patients (35.3%) showed the decreased levels of HbA1c after 3 months with mean change of -0.74±0.27%, and HbA1c values of 11 patients (21.5%) were less than 7%. In addition, the HbA1c level was significantly reduced in patients who reportedly followed the lifestyle modification such as diet and exercise for 3 months, compared with the one obtained from patients who refused this lifestyle change (p=0.002). CONCLUSION In this study, 35.3% of the patients with mild or moderately uncontrolled type 2 diabetes showed the significant improvement of HbA1c levels after 3 months by simply regulating their daily diet and exercise without change of medication. This suggests that the lifestyle modification is significantly associated with the improvement of glucose control.

Abstract
OBJECTIVE To evaluate the efficacy of ongoing group based diabetes self-management education (DSME) for patients with type 2 diabetes. METHODS 146 patients were randomised to either group education or waiting list control. Primary outcomes were A1C and patient activation measured with patient activation measure (PAM). RESULTS There were no differences in the primary outcomes between the groups at 12 months, but the control group had an increase in A1C of 0.3% points during follow-up. Diabetes knowledge and some self-management skills improved significantly in the intervention group compared to the control group. A sub group analysis was conducted for the quartile with the highest A1C at baseline (>7.7, n=18 in both groups). There were significant improvements within the intervention group at 12 month follow-up for both A1C and PAM and a trend for better outcome in the intervention group compared to the control. CONCLUSIONS The locally developed ongoing diabetes self-management education programs prevented an increase in A1C and can have an effect on A1C in patients with higher A1C level. PRACTICE IMPLICATIONS Locally developed programs may be less effective than programs developed for studies.

Abstract
AIMS To examine progression of glycaemia and cardiovascular risk factors in type 2 diabetes cases participating in a quality improvement initiative. METHODS 1108 new type 2 diabetes cases enrolled on the Otago Diabetes Register had clinical data recorded at baseline and 5 years. Means and standard deviations or percentages were calculated for variables of interest for <40, 40-59, 60-79 and 80-100 year age groups. p-Values for differences over time and among groups were calculated. Ordinal regression, with robust standard errors, was used to examine intensification of diabetes treatment. RESULTS For all age groups blood pressure and lipid levels approached recommended targets at 5 years (p<0.001). Glycated haemoglobin worsened, especially in the youngest age group (from 7.3±1.9% to 7.9±1.7%, p<0.001) who had the highest odds of more intense diabetes treatment at 5 years: 6.2 (95% CI 3.5-11.2) compared with 3.3 (95% CI 2.7-4.1) for 40-59-year olds, 2.8 (95% CI 2.3-3.3) for 60-79-year olds and 1.4 (95% CI 0.9-2.0) for ≥80-year olds. CONCLUSIONS Good management of type 2 diabetes patients, principally in primary care, can lead to improved blood pressure and lipid levels. Targets for glycaemic control and weight are less readily achieved especially among young age groups.

Abstract
This paper presents a summary of the evidence review group (ERG) report into the clinical effectiveness and cost-effectiveness of liraglutide in the treatment of type 2 diabetes mellitus, based upon the manufacturer’s submission to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal process. The manufacturer proposed the use of liraglutide as a second or third drug in patients with type 2 diabetes whose glycaemic control was unsatisfactory with metformin, with or without a second oral glucose-lowering drug. The submission included six manufacturer-sponsored trials that compared the efficacy of liraglutide against other glucose-lowering agents. Not all of the trials were relevant to the decision problem. The most relevant were Liraglutide Effects and Actions in Diabetes 5 (LEAD-5) (liraglutide used as part of triple therapy and compared against insulin glargine) and LEAD-6 [liraglutide in triple therapy compared against another glucagon-like peptide-1 agonist, exenatide]. Five of the six trials were published in full and one was then unpublished. Two doses of liraglutide, 1.2 and 1.8 mg, were used in some trials, but in the two comparisons in triple therapy, against glargine and exenatide, only the 1.8-mg dose was used. Liraglutide in both doses was found to be clinically effective in lowering blood glucose concentration [glycated haemoglobin (HbA1c)], reducing weight (unlike other glucose-lowering agents, such as sulphonylureas, glitazones and insulins, which cause weight gain) and also reducing systolic blood pressure (SBP). Hypoglycaemia was uncommon. The ERG carried out meta-analyses comparing the 1.2- and 1.8-mg doses of liraglutide, which suggested that there was no difference in control of diabetes, and only a slight difference in weight loss, insufficient to justify the extra cost. The cost-effectiveness analysis was carried out using the Center for Outcomes Research model. The health benefit was reported as quality-adjusted life-years (QALYs). The manufacturer estimated the cost-effectiveness to be £15,130 per QALY for liraglutide 1.8 mg compared with glargine, £10,054 per QALY for liraglutide 1.8 mg compared with exenatide, £10,465 per QALY for liraglutide 1.8 mg compared with sitagliptin, and £9851 per QALY for liraglutide 1.2 mg compared with sitagliptin. The ERG conducted additional sensitivity analyses and concluded that the factors that carried most weight were:
in the comparison with glargine, the direct utility effects of body mass index (BMI) changes and SBP, with some additional contribution from HbA1c
in the comparison with exenatide, HbA1c, with some additional effects from cholesterol and triglycerides
in the comparison with sitagliptin, HbA1c and direct utility effects of BMI changes.
The European Medicines Agency has approved liraglutide in dual therapy with other oral glucose-lowering agents. NICE guidance recommends the use of liraglutide 1.2 mg in triple therapy when glycaemic control remains or becomes inadequate with a combination of two oral glucose-lowering drugs. The use of liraglutide 1.2 mg in a dual therapy is indicated only in patients who are intolerant of, or have contraindications to, three oral glucose-lowering drugs. The use of liraglutide 1.8 mg was not approved by NICE. The ERG recommends research into the (currently unlicensed) use of liraglutide in combination with long-acting insulin.

Abstract
AIM To describe health-related quality of life in diabetes outpatients and investigate the impact of diabetic foot ulcers, by comparing a group of patients with and without diabetic foot ulcers complications. Secondary to study the impact of sociodemographic and clinical variables in the two groups. DESIGN Cross-sectional study. METHODS The study involved 130 diabetes outpatients and 127 diabetic foot ulcers patients. Health-related quality of life was measured with the generic questionnaire Short Form-36, consisting of eight dimensional scores. All scores were adjusted for differences in age and gender (estimated marginal means). Differences were compared with anova calculations, by the use of Predictive Analytics Software, PASW (version 17.0). RESULTS This study confirms that health-related quality of life differs significantly between disease subgroups when measured with Short Form-36. Diabetic foot ulcers had a major negative impact on 7/8 subscales on the Short Form-36 compared to the diabetes outpatients group. health-related quality of life decreased with increasing amount of complications and comorbidity in the diabetes outpatients group, with cardiovascular complications being the most pronounced predictor of lower health-related quality of life scores. CONCLUSION Patients who have developed diabetic foot ulcers reports much poorer health-related quality of life than compared to diabetes outpatients. Factors linked to the development of late complications were not detected in the diabetic foot ulcers group, such as cardiovascular comorbidity and neuropathy. RELEVANCE TO CLINICAL PRACTICE Health-related quality of life measurement in early stages of disease may detect patients at risk of a more serious disease course and who consequently are in need of a more intensive follow-up.

Abstract
OBJECTIVE To determine the extent to which intensive dietary intervention can influence glycaemic control and risk factors for cardiovascular disease in patients with type 2 diabetes who are hyperglycaemic despite optimised drug treatment. DESIGN Randomised controlled trial. SETTING Dunedin, New Zealand. PARTICIPANTS 93 participants aged less than 70 years with type 2 diabetes and a glycated haemoglobin (HbA(1c)) of more than 7% despite optimised drug treatments plus at least two of overweight or obesity, hypertension, and dyslipidaemia. INTERVENTION Intensive individualised dietary advice (according to the nutritional recommendations of the European Association for the Study of Diabetes) for six months; both the intervention and control participants continued with their usual medical surveillance. MAIN OUTCOME MEASURES HbA(1c) was the primary outcome. Secondary outcomes included measures of adiposity, blood pressure, and lipid profile. RESULTS After adjustment for age, sex, and baseline measurements, the difference in HbA(1c) between the intervention and control groups at six months (-0.4%, 95% confidence interval -0.7% to -0.1%) was highly statistically significant (P=0.007), as were the decreases in weight (-1.3 kg, -2.4 to -0.1 kg; P=0.032), body mass index (-0.5, -0.9 to -0.1; P=0.026), and waist circumference (-1.6 cm, -2.7 to -0.5 cm; P=0.005). A decrease in saturated fat (-1.9% total energy, -3.3% to -0.6%; P=0.006) and an increase in protein (1.6% total energy, 0.04% to 3.1%; P=0.045) in the intervention group were the most striking differences in nutritional intake between the two groups. CONCLUSIONS Intensive dietary advice has the potential to appreciably improve glycaemic control and anthropometric measures in patients with type 2 diabetes and unsatisfactory HbA(1c) despite optimised hypoglycaemic drug treatment. TRIAL REGISTRATION Clinical trials NCT00124553.

Abstract
BACKGROUND Survey findings report that 48% of people with type 2 diabetes use complementary and alternative medicine (CAM) practice. Publications suggest a high incidence of health promotion counseling in naturopathic practice, yet clinical data on risk factor changes are not available in the literature. OBJECTIVES The primary aim of this study was to describe clinical risk factor changes during the utilization of naturopathic CAM services in patients with type 2 diabetes. DESIGN A retrospective, observational study design was used to describe naturopathic care. SETTING Abstracted medical charts were from patients of the Bastyr Center for Natural Health in Seattle, WA. PARTICIPANTS The patients in this study had type 2 diabetes and received naturopathic care between 2001 and 2006. OUTCOMES Abstracted data included patient demographics, duration of care, number of visits, laboratory values for hemoglobin A1c (HbA1c), low density lipoprotein (LDL) and high density lipoprotein (HDL) cholesterol, triglycerides (TAG); and systolic/diastolic blood pressure (SPB, DBP). RESULTS Thirty-seven (37) patient records met inclusion criteria and were abstracted in detail. Mean and median duration of care were 27 and 20 months, respectively. The mean number of visits was 11. Significant mean changes in clinical laboratory risk factors over the duration of care were: -0.65% for HbA1c (p = 0.046), -45 mg/dL for TAG (p = 0.037), -7 mm Hg in SBP (p = 0.02), and -5 mm Hg in DBP (p = 0.003). Mean changes for cholesterol did not reach statistical significance. The percentage of patients who reached new control, had clinically significant risk factor improvements, or had any improvement was: 26%, 42%, and 68% for HbA1c, 7%, 28%, and 62% for LDL, 0%, 25%, and 39% for HDL, 14%, 38%, and 52% for TAG, 16%, 51%, and 86% for SBP, and 27%, 54%, and 70% for DBP. COMMENTS/CONCLUSIONS: These preliminary outcomes suggest that risk factor improvements occur during naturopathic care for diabetes, although the contribution of naturopathic care to these changes cannot be determined. Effectiveness and generalizability of naturopathic approaches in treating type 2 diabetes should be evaluated in controlled prospective studies in representative populations or randomized trials.

Abstract
CONTEXT Infusion of insulin acutely stimulates leptin production and chronic insulin treatment is associated with elevated serum leptin levels and body weight in subjects with type 2 diabetes. OBJECTIVE The objective of the study was to investigate the relationship between insulin administration, leptin levels, and weight gain in subjects with type 2 diabetes. DESIGN This was a post hoc analysis of two randomized, controlled trials. SETTING The study was conducted at an outpatient clinic. SUBJECTS Subjects included 35 (study 1) and 32 (study 2) poorly controlled oral hypoglycemic agent (OHA)-treated type 2 diabetic subjects. INTERVENTION Study 1: subjects were investigated during a hyperinsulinemic, euglycemic glucose clamp and 12 months after being randomly allocated to start insulin or continue on OHAs. Study 2: 1 yr treatment with either OHAs and lifestyle intervention or insulin with or without concomitant lifestyle intervention. MAIN OUTCOME MEASURE Changes in serum leptin levels during clamp and during 1 yr of treatment in relationship to changes in body weight. RESULTS Study 1: during acute insulin infusion leptin levels increased by 10% (P < 0.001). During 1 yr of insulin therapy, mean body weight increased by 6%, whereas the fasting leptin levels increased by 108% (both P < 0.001). The weight gain observed at 1 yr correlated with the increase in leptin levels observed during the clamp (r = 0.62, P = 0.003). Study 2: mean body weight increased by 4% (P < 0.01), whereas leptin levels increased by 56% (P < 0.001) during 1 yr of insulin treatment and the increase in leptin preceded the increase in body weight. CONCLUSIONS Significant correlations were observed between insulin's effect on serum leptin levels and the increase in weight that accompanied insulin therapy.

Abstract
BACKGROUND Type 2 diabetes is a common and costly chronic disease which is associated with significant premature mortality and morbidity. Although patient education is an integral component of diabetes care, there remain uncertainties regarding the effectiveness of different methods and modes of education. OBJECTIVES To evaluate the effectiveness of individual patient education on metabolic control, diabetes knowledge and psychosocial outcomes. SEARCH STRATEGY Multiple electronic bibliographic databases were searched, including The Cochrane Library, MEDLINE, Premedline, ERIC, Biosis, AMED, Psychinfo, EMBASE, CINAHL, APAIS-health, Australian Medical Index, Web of Science, dissertation abstracts and Biomed Central. SELECTION CRITERIA Randomized controlled and controlled clinical trials which evaluated individual education for adults with type 2 diabetes. The intervention was individual face-to-face patient education while control individuals received usual care, routine treatment or group education. Only studies that assessed outcome measures at least six months from baseline were included. DATA COLLECTION AND ANALYSIS Information was extracted by two reviewers who summarized both study characteristics and outcome statistics. A meta-analysis using a fixed-effect model was performed if there were adequate studies with a specified outcome of sufficient homogeneity. For outcomes where there were too few studies or the assessment measurements were not standardized or variable, the results were summarised qualitatively. MAIN RESULTS Nine studies involving 1359 participants met the inclusion criteria. Six studies compared individual education to usual care and three compared individual education to group education (361 participants). There were no long-term studies and overall the quality of the studies was not high. In the six studies comparing individual face-to-face education to usual care, individual education did not significantly improve glycaemic control (weighted mean difference (WMD) in HbA1c -0.1% (95% confidence interval (CI) -0.3 to 0.1, P = 0.33) over a 12 to 18 month period. However, there did appear to be a significant benefit of individual education on glycaemic control in a subgroup analysis of three studies involving participants with a higher mean baseline HbA1c greater than 8% (WMD -0.3% (95% CI -0.5 to -0.1, P = 0.007). In the two studies comparing individual to group education, there was no significant difference in glycaemic control between individual or group education at 12 to 18 months with a WMD in HbA1c of 0.03% (95% CI -0.02 to 0.1, P = 0.22). There was no significant difference in the impact of individual versus usual care or group education on body mass index systolic or diastolic blood pressure. There were too few studies to perform a meta-analysis on the effect of individual education on dietary self management, diabetes knowledge, psychosocial outcomes and smoking habits. No data were available on the other main outcome measures of diabetes complications or health service utilization and cost analysis in these studies. AUTHORS' CONCLUSIONS This systematic review suggests a benefit of individual education on glycaemic control when compared with usual care in a subgroup of those with a baseline HbA1c greater than 8%. However, overall there did not appear to be a significant difference between individual education and usual care. In the small number of studies comparing group and individual education, there was an equal impact on HbA1c at 12 to 18 months. Additional studies are needed to delineate these findings further.

Abstract
UNLABELLED Guidance has been published on the choice of initial insulin regimen for patients with type 2 diabetes [NPH (isophane) insulin or a long-acting insulin analogue] but not on how to choose a second regimen when glycaemic control becomes unsatisfactory. AIMS To develop pragmatic clinical guidance for choosing a second-line insulin regimen tailored to the individual needs of patients with type 2 diabetes after failure of first-line insulin therapy. METHODS Formulation of a consensus by expert panel based on published evidence and best clinical practice, taking into account patient preferences, lifestyle and functional capacity. RESULTS Six patient-dependent factors relevant to the choice of second-line insulin regimen and three alternative insulin regimens (twice-daily premixed, basal-plus and basal-bolus) were identified. The panel recommended one or more insulin regimens compatible with each factor, emphasising the fundamental importance of a healthy lifestyle that includes exercise and weight reduction. These recommendations were incorporated into an algorithm to provide pragmatic guidance for clinicians. CONCLUSION The three alternative insulin regimens offer different benefits and drawbacks and it is important to make the right choice to optimise outcomes for patients.

Abstract
Insulin therapy or intensification of insulin therapy commonly results in weight gain in both type 1 and type 2 diabetes. This weight gain can be excessive, adversely affecting cardiovascular risk profile. The spectre of weight gain can increase diabetic morbidity and mortality when it acts as a psychological barrier to the initiation or intensification of insulin, or affects adherence with prescribed regimens. Insulin-associated weight gain may result from a reduction of blood glucose to levels below the renal threshold without a compensatory reduction in calorie intake, a defensive or unconscious increase in calorie intake caused by the fear or experience of hypoglycaemia, or the 'unphysiological' pharmacokinetic and metabolic profiles that follow subcutaneous administration. There is, however, scope for limiting insulin-associated weight gain. Strategies include limiting dose by increasing insulin sensitivity through diet and exercise or by using adjunctive anorectic or insulin-sparing pharmacotherapies such as pramlintide or metformin. Insulin replacement regimens that attempt to mimic physiological norms should also enable insulin to be dosed with maximum efficiency. The novel acylated analogue, insulin detemir, appears to lack the usual propensity for causing weight gain. Elucidation of the pharmacological mechanisms underlying this property might help clarify the mechanisms linking insulin with weight regulation.

Abstract
AIMS/HYPOTHESIS Adipokines may be important in mediating signals from adipocytes to insulin-sensitive tissue and vasculature. We studied the effect of different glucose-lowering therapies on serum levels of plasminogen activator inhibitor-1 (PAI-1), high-sensitivity C-reactive protein (hs-CRP), TNF-alpha, leptin, adiponectin and ghrelin in patients with type 2 diabetes. SUBJECTS AND METHODS Twenty-eight patients with poorly controlled type 2 diabetes who were receiving oral hypoglycaemic agents were allocated to one of the following groups, and treated for 1 year: (1) lifestyle intervention (L); (2) insulin treatment (I); and (3) combined treatment (L+I). RESULTS Similar improvements in glycaemic control occurred in all three groups. There was a reduction in body weight of 3.0 kg (median) (95% CI -5.9 to -2.0) in group L, whereas in groups L+I and I body weight increased by 3.5 kg (95% CI 1.5-4.9) and 4.9 kg (95% CI -3.1 to 8.2), respectively. By trend analyses, group L had reduced levels of PAI-1 (p=0.002), hs-CRP (p<0.0001) and TNF-alpha (p=0.006), while no significant changes were observed in the levels of leptin or adiponectin. In group I, the median levels of PAI-1 (p=0.008), TNF-alpha (p=0.058) and leptin (p=0.004) increased. In the L+I group there was a reduction in PAI-1 levels (p=0.014) and an increase in levels of leptin (p<0.001). The differences in changes in the levels of PAI-1, hs-CRP, TNF-alpha and leptin between groups were also significant (all p<0.01). CONCLUSIONS/INTERPRETATION Improvement of glycaemic control through lifestyle intervention in type 2 diabetes had more beneficial effects on adipokine levels than when the same lowering of HbA(1c) was achieved with insulin treatment.
