Abstract
Diabetic retinopathy (DR) is a common microvascular complication in young individuals with type 1 diabetes. It is recommended to implement structured screening programs and adopt an appropriate referral mechanism at all levels of the health system to prevent vision loss in this disease. We developed and pilot-tested the feasibility of a comprehensive DR screening model at a tertiary care diabetes clinic in India. The model comprised an affordable DR screening facility at the diabetes clinic, structured education sessions, and annual inhospital diabetes complication screening camps. Over the span of 2 years, we screened 413 eligible patients with type 1 diabetes and 17.4% (n = 72) had any form of DR in at least one eye. Half of the retinopathy positive patients had mild DR. However, only one-third of newly diagnosed patients reported to the eye care facility for DR management. Based on this study, it is feasible to screen all patients with type 1 diabetes for DR by increasing awareness and providing opportunities for DR screening at a tertiary care diabetes clinic. Our model combined with formal referral and follow-up systems would be a potentially scalable approach for DR prevention and management at diabetes care facilities in India.

Evaluating fear of hypoglycemia, pediatric parenting stress, and self-efficacy among parents of children with type 1 diabetes and their correlation with glycemic control. Med J Islam Repub Iran 2019; 32:119. [PMID: 30815414 PMCID: PMC6387803 DOI: 10.14196/mjiri.32.119] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2017] [Indexed: 12/05/2022] Open
Abstract
Background: This study was designed to determine the level of fear of hypoglycemia (FoH), pediatric parenting stress and selfefficacy in parents of children with type 1 diabetes (T1D).
Methods: In this cross-sectional study, 61 families of children with T1D who had been diagnosed for at least 6 months recruited from "Gabric Diabetes Education Association" in Tehran. Sixty mothers and 41 fathers of 61 children (26 girls, age: 6.0-12.7 years) were assessed using the Hypoglycemia Fear Survey-Parent (HFS-P), Pediatric Inventory for Parents (PIP) and Self-Efficacy for Diabetes Scale-Parent (SED-P) questionnaires. Pearson correlation analysis was used to compute the correlation between HFS-P, PIP and SEDP scores separately for mother and fathers.
Results: Only 8.3% of children had controlled diabetes. Internal reliability of the Persian version of all questionnaires was good. FoH were higher for mothers. Mothers whose children had diabetes for less than two years had significantly lower mean HFS-Behavior subscale (HFS-B) scores than mothers whose children had diabetes for more than two years. There was a positive correlation between fathers’ mean HFS-B score and children’s total insulin dose per day. Parents' FoH score was positively correlated with increased pediatric parenting stress. Findings also showed considerable emotional distress in 51% of mothers and 29.7% of fathers. Frequency of selfmonitoring blood glucose tests (SMBG) correlated negatively with HbA1c.
Conclusion: We concluded that parents with high levels of FoH and stress may benefit from diabetes education. Important implications for education are considering psychological adjustment, recognizing diabetes-related fear and stress in parents, encouraging fathers to become actively involved in the child’s diabetes management and emphasizing the importance of SMBG.

Abstract
OBJECTIVE To assess national differences in diabetes care and quality of life (QOL) between individuals with long-standing type 1 diabetes (≥50 years) in Canada and the U.S. RESEARCH DESIGN AND METHODS Cross-sectional data from identical surveys administered in the Canadian Study of Longevity in Diabetes and the Joslin Medalist Study, collected in 2013-2016 and 2005-2011, respectively, were compared. Laboratory values and ophthalmic examination were completed by clinical care physicians for Canadians and the Joslin Clinic for Americans. Univariate comparisons and multivariable regression for HbA1c, QOL, insulin pump use, and coronary artery disease (CAD) were performed. Nephropathy, CAD, and peripheral arterial disease (PAD) were self-reported; neuropathy was defined by a Michigan Neuropathy Screening Instrument (Questionnaire component) score ≥3, and proliferative retinopathy was documented from ophthalmic examination. QOL was self-reported on an ordinal scale. RESULTS Three hundred sixty-one Canadians and 668 Americans had similar ages (mean 65.78 years [SD 8.67] vs. 66.38 years [7.66], P = 0.27) and durations of diabetes (median 53.00 years [interquartile range 51.00, 58.00] vs. 53.00 years [51.00, 57.00], P = 0.51). Canadians had higher HbA1c (mean 7.53% [SD 1.03] [59 mmol/mol] vs. 7.22% [0.98] [55 mmol/mol], P < 0.0001), lower QOL (36.9% vs. 48.7% with "excellent" QOL, P = 0.0002), and less CAD (29.7% vs. 41.2%, P = 0.0003) and insulin pump use (43.3% vs. 55.6%, P = 0.0002). Other complication rates were similar. Residual differences for Canadians compared with Americans remained after adjustment for age, sex, CAD, PAD, education, and relevant a priori selected variables: 0.28% higher HbA1c (P = 0.0004); and odds ratios of 0.68 (95% CI 0.51, 0.90), 0.46 (0.31, 0.68), and 0.71 (0.52, 0.96) for higher QOL, CAD, and insulin pump use, respectively. CONCLUSIONS Although Canadians and Americans have similar rates of complications other than CAD, further research is required to understand why Canadians have higher HbA1c levels, lower QOL, and less insulin pump use.

Abstract
OBJECTIVE To test whether laser speckle contrast imaging (LSCI) coupled with physiological post-occlusive reactive hyperemia (PORH) and pharmacological iontophoresis of acetylcholine (ACh) as local vasodilator stimuli could distinguish between cutaneous microvascular responses of Type 1 Diabetes (T1DM)'s patients with endothelial dysfunction and that of healthy controls. METHODS Patients with T1DM aged ≥12years completed a clinical-epidemiological questionnaire. Data detailing patients' such as daily insulin dose, duration of diabetes, and use of pharmaceuticals such as antihypertensive drugs and statins that could interfere with endothelial function were obtained. Vascular reactivity was assessed in the forearm by LSCI and PORH at baseline and during iontophoresis of ACh using increasing anodic currents of 30, 60, 90, 120, 150 and 180μA in 10second intervals. RESULTS This study included 50 patients with T1DM and 30 control subjects. The mean resting flux did not differ between patients and control subjects. T1DM patients exhibited endothelial dysfunction upon challenge with physiological or pharmacological stimuli. The microvascular response to both ACh and PORH (i.e., maximum response at peak and amplitude) were significantly reduced in patients with diabetes compared with control subjects (p<0.001). CONCLUSION We demonstrated that endothelium-dependent skin microvascular vasodilator responses are significantly impaired in patients with T1DM compared to healthy subjects investigated using LSCI coupled with ACh iontophoresis and PORH. Additionally, we find that LSCI is a promising methodology for studying physiological vascular reactivity in T1DM.

Abstract
OBJECTIVE This study was designed to test the reliability of a Persian version of 2 questionnaires to assess the level of fear of hypoglycemia (FoH) and self-efficacy in diabetes management and their association with glycated hemoglobin (A1C) and parents' demographic characteristics in a sample of children with type 1 diabetes. DESIGN We assessed 61 children with type 1 diabetes (35 boys and girls, 6.0 to 12.7 years of age) using the Hypoglycemia Fear Survey-Child version (HFS-C) and Self-Efficacy for Diabetes Scale-Child version (SED-C). Their glycemic control was evaluated by A1C levels. RESULTS The internal consistency of the Persian version of HFS-C and SED-C were very good. Our results showed that children older than 10 years of age report lower levels of FoH, which are related to higher levels of self-efficacy (r=-.30, p=0.025 and r=-.30, p=0.02, respectively). Of the children, 42.3% of girls and 31.4% of boys reported that low blood sugar is a big problem for them. These findings suggest that FoH is a significant concern for this target group. Only 19.7% of children had controlled diabetes based on A1C levels. There was no significant association between higher A1C levels and other variables, including HFS-C, SED-C and parents' demographic characteristics. CONCLUSIONS The Persian version of HFS-C and SED-C are reliable and valid measures of the fear of hypoglycemia and of self-efficacy in children with type 1 diabetes, and these questionnaires could be used in our country for identifying those children who may need diabetes education and other supports. The association between greater self-efficacy and lower fear of hypoglycemia suggests that addressing self-efficacy in diabetes education courses may be effective in helping to overcome FoH.

Abstract
BACKGROUND Type 1 diabetes (T1DM) is considered to be one of the most significant risk factors for the development of coronary artery disease (CAD). However, the specific risk predictor models for T1DM are subject to many limitations. CASE PRESENTATION We report the case of a 42-year-old Caucasian woman presenting with T1DM for 26 years. During her chronic hyperglycemic evolution (mean of HbA1c > 3 percentage points above the superior limit) without microvascular complications, this patient presented with early and aggressive coronary artery disease, despite the lack of classical risk factors for CAD CONCLUSIONS: The rapidly progressive macrovascular disease observed in this case demonstrates the different degrees of aggressiveness and unpredictable clinical evolution observed in some cases. It also confirms the need for a multi-factorial, early and optimized clinical management regime.

Abstract
AIM AND OBJECTIVE To describe the study design of a randomised controlled trial with the aim of comparing two different regimes for children with newly diagnosed type 1 diabetes; hospital-based care and hospital-based home care. BACKGROUND Procedures for hospital admission and sojourn in connection with diagnose vary greatly worldwide and the existing evidence is insufficient to allow for any conclusive determination of whether hospital-based or home-based care is the best alternative for most families. Comparative studies with adequate power and outcome measurements, as well as measurements of cost-effectiveness are needed. DESIGN The study design was based on the Medical Research Council framework for complex interventions. After two to three days with hospital-based care, children between the ages of 3 and 16 were randomised to receive either continued hospital-based care for a total of 1-2 weeks or hospital-based home care, which refers to specialist care in a home-based setting. The trial started in March 2008 at a University Hospital in Sweden and was closed in September 2011 when a sufficient number of children according to power calculation, were included. The primary outcome was the child's metabolic control during the following two years. Secondary outcomes were set to evaluate the family and child situation as well as the organisation of care. DISCUSSION Childhood diabetes requires families and children to learn to perform multiple daily tasks. Even though intervention in health care is complex with several interacting components entailing practical and methodological difficulties, there is nonetheless, a need for randomised controlled trials in order to evaluate and develop better systems for the learning processes of families that can lead to long-term improvement in adherence and outcome.

Abstract
Distal symmetrical polyneuropathy (DSP) is the most common type of diabetic neuropathy, but often difficult to diagnose reliably. We evaluated the cross-sectional association between three point-of-care devices, Vibratron II, NC-stat(®), and Neurometer(®), and two clinical protocols, MNSI and monofilament, in identifying those with DSP, and/or amputation/ulcer/neuropathic pain (AUP), the two outcomes of major concern. This report presents data from 195 type 1 diabetic participants of the Epidemiology of Diabetes Complications (EDC) Study attending the 18-year examination (2004-2006). Participants with physician-diagnosed DSP, AUP or who were abnormal on the NC-stat, and the Vibratron II, MNSI, and monofilament were older (p<0.05) and had a longer duration of diabetes (p < 0.05). There was no difference by sex for DSP, AUP, or any testing modality, with the exception of NCstat (motor). The Vibratron II and MNSI showed the highest sensitivity for DSP (>87%) and AUP (>80%), whereas the monofilament had the highest specificity (98% DSP, 94% AUP) and positive predictive value (89% DSP, 47% AUP), but lowest sensitivity (20% DSP, 30% AUP). The MNSI also had the highest negative predictive value (83%) and Youden's Index (37%) and currently presents the single best combination of sensitivity and specificity of DSP in type 1 diabetes.

Abstract
Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by absolute insulin deficiency resulting from the progressive immune-mediated destruction of pancreatic islet beta cells. It is thought to be triggered by as yet unidentified environmental factors in genetically susceptible individuals, the major genetic contribution coming from loci within the HLA complex, in particular HLA class II. The worldwide incidence of T1D varies by at least 100-fold, being highest in Finland and Sardinia (Italy) and lowest in Venezuela and China. The incidence has been increasing worldwide at an annual rate of approximately 3%. While genetic factors are thought to explain some of the geographic variability in T1D occurrence, they cannot account for its rapidly increasing frequency. Instead, the declining proportion of newly diagnosed children with high-risk genotypes suggests that environmental pressures are now able to trigger T1D in genotypes that previously would not have developed the disease during childhood. Although comparisons between countries and regions with low and high-incidence rates have suggested that higher socioeconomic status and degree of urbanization are among the environmental factors that play a role in the rising incidence of T1D, the findings are too inconsistent to allow firm conclusions. Morbidity and mortality as well as causes of death also show considerable geographic variation. While glycemic control has been identified as a major predictor of the micro- and macrovascular complications of T1D and shows considerable geographical variability, it does not appear to be the only factor involved in the regional differences in complication rates. The role of genetics in susceptibility to nephropathy, retinopathy and other diabetic complications largely remains to be explored.

Abstract
PURPOSE Check the evolution of type 1(T1) diabetic patients to hypertension and prehypertension and baseline factors related to final blood pressure levels (BP). METHODS Observational study involving 127 T1 diabetic patients submitted to clinical and laboratory evaluation and followed by for 5 (2.4-9.2) years. RESULTS From the initially normotensive patients, 21.7% developed prehypertension, 4.7% developed hypertension and 73.6% remained with normal BP. From the prehypertensive patients, 35% returned to normal BP, 50% remained prehypertensive and 15% developed hypertension. The relative risk for hypertension development was 3.2 (0.8-12.3) in the prehypertensive compared to the normotensive group. The prevalence of prehypertension and hypertension increased from 15.7% to 26% and 0.8% to 7% respectively. Levels of serum creatinine predicted final levels of systolic and diastolic BP. CONCLUSION It is emphasized the importance of renal function and BP evaluation even when they are in normal range to minimize the deleterious effects of hypertension in the development of nephropathy and cardiovascular disease.

Abstract
AIMS/HYPOTHESIS Cardiac autonomic neuropathy is associated with increased morbidity and mortality rates in patients with type 1 diabetes. The prevalence of early autonomic abnormalities is relatively high compared with the frequency of manifest clinical abnormalities. Thus, early autonomic dysfunction could to some extent be functional and might lead to an organic disease in a subgroup of patients only. If this is true, manoeuvres such as slow deep-breathing, which can improve baroreflex sensitivity (BRS) in normal but not in denervated hearts, could also modify autonomic modulation in patients with type 1 diabetes, despite autonomic dysfunction. METHODS We compared 116 type 1 diabetic patients with 36 matched healthy control participants and 12 heart-transplanted participants with surgically denervated hearts. Autonomic function tests and spectral analysis of heart rate and blood pressure variability were performed. BRS was estimated by four methods during controlled (15 breaths per minute) and slow deep-breathing (six breaths per minute), and in supine and standing positions. RESULTS Conventional autonomic function tests were normal, but resting spectral variables and BRS were reduced during normal controlled breathing in patients with type 1 diabetes. However, slow deep-breathing improved BRS in patients with type 1 diabetes, but not in patients with surgically denervated hearts. Standing induced similar reductions in BRS in diabetic and control participants. CONCLUSIONS/INTERPRETATION Although we found signs of increased sympathetic activity in patients with type 1 diabetes, we also observed a near normalisation of BRS with a simple functional test, indicating that early autonomic derangements are to a large extent functional and potentially correctable by appropriate interventions.

Abstract
OBJECTIVE Children with type 1 diabetes are usually associated with cardiovascular autonomic neuropathy. The present study explored the influence of physical activity on their autonomic nervous function by measuring the heart rate variability (HRV). MATERIALS AND METHODS A total of 93 type 1 diabetic children and 107 healthy control subjects were enrolled. The Physical Activity Questionnaire for Children (PAQ-C) was adopted to determine the physical activity level as low, moderate, or high activity. HRV was determined by frequency analysis and measured in both resting and active states. RESULTS Children with type 1 diabetes had significantly lower HRV than that of healthy control subjects in resting state but not in active state. The decreased HRV in diabetic children was observed only in subjects with low physical activity. The HRV in diabetic children with moderate to high physical activity, however, was not different from that of their healthy controls. CONCLUSIONS Diabetic children should be encouraged to engage in physical activity with more intensity, which can benefit their autonomic nervous function. Nevertheless, the potential risk of vigorous activity still needs our concern.

AIMS To study the cumulative incidence of hospitalization for severe diabetic vascular complications in childhood onset type 1 diabetes patients with special regards to age at onset and gender. METHODS The Swedish Childhood Diabetes Register (SCDR) was linked to the Swedish Hospital Discharge Register up to 31 December 2004. The following diagnoses were traced: diabetic kidney disease, myocardial infarction, stroke, lower limb arterial disease and diabetes with multiple complications. Cox proportional hazards survival method was applied with the following covariates: maternal age, birthweight deviation from gestational week standard, age at onset and gender. RESULTS Until 31 December 9974 children had been followed for at least 10 years corresponding to 141 839 person years at risk and 103 (7.3 per 1000 person years) had been hospitalized at least once at the maximum duration of follow-up of 26 years. Diabetic kidney disease was the most common cause of hospitalization and 63 patients had more than one diabetic complication. Female gender (RR=2.02, 95% CI=1.05-3.89) and age at onset of diabetes (RR=1.37, 95% CI=1.20-1.56) were significant risk factors for severe complication. CONCLUSIONS Hospitalization for severe diabetic complications at a maximum follow-up of 26 years is rather low in Sweden. There is a higher hospitalization rate among females than among males, and also among patients diagnosed with diabetes after 10 years of age than among patients diagnosed before the age of 10 years.

Abstract
Type 1 diabetes mellitus (T1DM) commonly occurs in childhood or adolescence, although the rising prevalence of type 2 diabetes mellitus (T2DM) in these age groups is now being seen worldwide. Diabetic nephropathy (DN) develops in 15-20% of subjects with T1DM and in similar or higher percentage of T2DM patients, causing increased morbidity and premature mortality. Although overt DN or kidney failure caused by either type of diabetes are very uncommon during childhood or adolescence, diabetic kidney disease in susceptible patients almost certainly begins soon after disease onset and may accelerate during adolescence, leading to microalbuminuria or incipient DN. Therefore, all diabetics warrant ongoing assessment of kidney function and screening for the earliest manifestations of renal injury. Pediatric health care professionals ought to understand about risk factors, strategy for prevention, method for screening, and treatment of early DN. This review considers each form of diabetes separately, including natural history, risk factors for development, screening for early manifestations, and strategy recommended for prevention and treatment of DN in children and adolescents.

Abstract
AIMS Gastroparesis is a common gastrointestinal complication in diabetes mellitus, whereas dysfunction in the other gastrointestinal organs has been less thoroughly investigated. Furthermore, it is not known whether there is any relationship between motility and dysmotility between these organs. The aim of this study was to examine whether diabetic patients with gastrointestinal symptoms also have motility disturbances in the oesophagus and stomach and, if so, whether there are any associations between these disturbances. METHODS Thirty-one patients with diabetes mellitus who complained of gastrointestinal symptoms were asked to complete a questionnaire about their symptoms. They were further investigated with oesophageal manometry and gastric emptying scintigraphy. RESULTS Fifty-eight per cent of the patients had abnormal oesophageal function, and 68% had delayed gastric emptying. Abdominal fullness was the only symptom that related to any dysfunction, and it was associated with delayed gastric emptying (P = 0.02). We did not find any relationship in motility or dysmotility between the oesophagus and the stomach. CONCLUSION Oesophageal dysmotility, as well as gastroparesis, are common in patients with diabetes who have gastrointestinal symptoms. It is important to investigate these patients further, to be able to reach an accurate diagnosis and instigate appropriate treatment. Our findings indicate that the oesophagus and the stomach function as separate organs and that pathology in one does not necessarily mean pathology in the other.

Abstract
AIMS The incidence of type 1 diabetes is increasing in many parts of Asia, where resources may not enable targets for glycemic control to be achieved. The aims of this study were to describe glycemic control, diabetes care, and complications in youth with type 1 diabetes from the Western Pacific Region and to identify factors associated with glycemic control and hypoglycemia. METHODS A cross-sectional clinic-based study on 2312 children and adolescents (aged <18 years; 45% males) from 96 pediatric diabetes centers in Australia, China, Hong Kong, Indonesia, Japan, Malaysia, Philippines, Singapore, South Korea, Taiwan, and Thailand was conducted. Clinical and management details were recorded, and finger-pricked blood samples were obtained for central glycated hemoglobin (HbA(1c)). RESULTS The median age of the patients was 12.5 years [interquartile range (IQR)=9.4-15.3 years]; diabetes duration, 4.4 years (IQR=2.5-7.2 years); and HbA(1c) level, 8.3% (IQR 7.4%-9.7%). Insulin treatment consisted of one or two daily injections in 61% of the patients (range=22%-90% by country), and home blood glucose monitoring (range=67%-100%) was practiced by 96%. HbA(1c) level was significantly associated with country, age, diabetes duration, sex, insulin dose per kilogram, insulin regimen, and frequency of home blood glucose measurement in multiple regression analysis. The incidence of severe hypoglycemia, defined as any episode requiring assistance in the previous 3 months, was 73 per 100 patient-years and was associated with country, male sex, higher HbA(1c) level, an insulin regimen with three or more injections, and more frequent home blood glucose testing. The incidence of diabetic ketoacidosis was 10 per 100 patient-years and was associated with country, higher HbA(1c) level, and higher insulin dose per kilogram. CONCLUSIONS There is marked variability in glycemic control, hypoglycemia, complication rates, and diabetes care among children from the Western Pacific Region. Most are not achieving adequate glycemic control, placing them at high risk of microvascular complications.

Abstract
AIM To estimate the risk of diabetic nephropathy and associated risk factors in a nationwide cohort of childhood-onset type 1 diabetes mellitus (T1DM) and 19-30 yr of diabetes duration. METHODS Patients diagnosed with childhood-onset T1DM (<15 yr) from 1973 through 1982, who previously (1989-1990) participated in a clinical examination to assess diabetic complications, were invited for a new examination in 2002-2003. Of 355 eligible patients, 299 participated (84.2%), and complete urine samples for evaluation of albuminuria were obtained from 295 patients, with a mean age of 33 yr (range 20.9-44.0) and mean diabetes duration of 24 yr (range 19.3-29.9). Persistent microalbuminuria and overt nephropathy [albumin excretion rate (AER) 15-200 microg/min and AER > 200 microg/min, respectively] in at least two out of three consecutive overnight urine samples were defined as diabetic nephropathy. RESULTS Overt nephropathy was found in 7.8% [95% confidence interval (CI) 4.7-10.9] and persistent microalbuminuria in 14.9% (95% CI 10.8-19.0) of the subjects. Hemoglobin A1c (HbA1c) (p = 0.001), systolic blood pressure (BP) (p = 0.002), total cholesterol (p = 0.019), and C-reactive protein (CRP) (p = 0.019) were associated with diabetic nephropathy. Significant predictors in 1989-1990 for the development of diabetic nephropathy in 2002-2003 were HbA1c (p < 0.001), AER (p = 0.007), and cholesterol (p = 0.022). CONCLUSIONS In a subgroup of patients diagnosed with childhood-onset T1DM in 1973-1982, 7.8% had overt nephropathy after 19-30 yr of diabetes duration, which is low compared with studies from other countries. HbA1c, systolic BP, total cholesterol, and CRP were each independently associated with diabetic nephropathy.

Abstract
The objectives of this study were to describe the global geographic variation of microvascular and macrovascular complications in childhood onset type 1 diabetes (T1D) and to relate any such variation to diabetes care activities such as self blood glucose monitoring and intensive insulin therapy. The DiaComp study is a multinational (17 countries) cross-sectional study of complications in T1D (n=2,657). All participants were diagnosed at < 15 years of age and had a diabetes duration of 5-24 years when surveyed. Complications were assessed by self-report of physician diagnosis. Twenty-two centres in 17 countries achieved at least a 67% response rate and are included in the analyses. Central European centres exhibited high rates of retinopathy (Lithuania=31.6%, Romania=24.2%), laser treatment (Lithuania=25.4%) and neuropathy (Lithuania=29.9%, Romania=12.4%) in those with short duration of diabetes (5-15 years), as did Cuba for neuropathy (15.4%). For retinopathy the geographic variation in the short-duration group was also pronounced, ranging from 1.6% in Italy to 41.6% in Lithuania, and from 0% in Brazil, Italy and Australia, to 29.9% in Lithuania for laser treatment. Variation was less dramatic for the prevalence of complications in the long-duration group (15-25 years). Hypertension and duration were strong consistent predictors of all complications, while women had higher prevalence for half the complications (retinopathy, laser treatment and renal disease). Intensive insulin therapy and self-monitoring of blood glucose showed little association with prevalence of complications. In conclusion, this first population-based account of the geographic variation of T1D complications has demonstrated substantial variation. However, the healthcare practice variables that were measured contributed little toward explaining this variation.

Abstract
We sought to determine the extent to which the geographic variation in the complications of type 1 diabetes (T1D) may reflect the socioeconomic status (SES) conditions and health care performance (HCP) of countries around the world. The World Health Organization (WHO) DiaMond complications study (DiaComp) is a multinational, cross-sectional study of complications in T1D. Information on complications was identified for 892 subjects from 14 clinical centers in 12 countries. All participants were diagnosed with diabetes in childhood (<15 years of age) and had disease duration of 5-24 years. Complications were assessed by self-report, and by clinical exam, with microalbuminuria identified by Micral II dipstick, neuropathy by the Michigan Neuropathy Screening Instrument exam and hypertension using the HDFP protocol. These data were linked to center-specific information on the local social and economic landscape, health care access and diabetes management practices and health care costs. Country-specific indicators of social and economic development were also linked to the complications data. Both diabetes complications and economic and health care factors vary widely across the DiaComp centers. Health system performance, as measured by disability adjusted life expectancy (DALE), gross national investment (GNI) per capita and purchasing power all showed strong consistent correlations with complications, and significant independent associations with complication prevalence after controlling for HbA1c and hypertension. In conclusion, health system performance, social distribution of wealth and purchasing power may play important roles in explaining the geographic variation of diabetes complications.

Abstract
OBJECTIVE The development of diabetic neuropathy (DN) is predicted by cardiovascular risk factors associated with insulin resistance. As inflammation seems to be implicated in the pathogenesis of insulin resistance, we investigated whether subjects with type 1 diabetes mellitus (T1DM) and DN have an increase in plasma concentrations of inflammatory proteins involved in insulin resistance. DESIGN Cross-sectional. Patients One hundred twenty subjects, all diagnosed with T1DM 14 years before. MEASUREMENTS (1) Sex, age, body mass index, waist-to-hip ratio (WHR), blood pressure, smoking, alcohol intake, insulin dose, HbA1c and lipid profile; (2) DN (peripheral and cardiac autonomic), retinopathy and nephropathy; (3) plasma concentrations of soluble fractions of tumour necrosis factor alpha receptors 1 and 2 (sTNFR1 and sTNFR2), interleukin-6, high-sensitive C-reactive protein, adiponectin and leptin; and (4) insulin resistance (by way of a mathematical estimation of the glucose disposal rate - eGDR-). RESULTS Thirty-six subjects had DN and 84 did not. Subjects with DN received higher insulin doses (57.6 +/- 16.7 vs. 49.2 +/- 15.0 IU/day; P = 0.008) and had higher WHR (0.85 +/- 0.07 vs. 0.81 +/- 0.10; P = 0.007) and HbA1c values (8.5 (7.6-9.6) vs. 7.7 (7.3-8.9)%; P = 0.049) than subjects without DN. They also had higher values of sTNFR1 (2.42 +/- 0.60 vs. 1.96 +/- 0.66 microg/l; P = 0.001) and sTNFR2 (4.73 +/- 1.33 vs. 4.14 +/- 1.09 microg/l; P = 0.015), and were more insulin resistant (eGDR values: 7.28 (5.83-8.03) vs. 8.30 (7.17-9.03) mg kg(-1) min(-1); P = 0.003). The relationship between DN and either sTNFR1 or sTNFR2 remained essentially unchanged after adjusting for several confounders, including glycaemic control, WHR, lipid profile, blood pressure and other microvascular complications (OR for sTNFR1: 2.592 (1.222-5.498), P = 0.013; OR for sTNFR2: 2.124 (1.258-3.587), P = 0.005). CONCLUSIONS The activity of the TNF-alpha system is increased in subjects with type 1 diabetes mellitus and diabetic neuropathy, regardless of their glycaemic control and cardiovascular risk factors associated with insulin resistance. These results suggest that TNF-alpha may play a pathogenic role in the development of diabetic neuropathy.
