Abstract
Diabetes affects men and women differently and the mistaken assumption of equality in its clinical expression can lead to errors and delays in the diagnostic process and the therapeutic strategy adopted. The objective is to show the gender differences that influence the approach to this pathology and what the role of the family doctor is in the monitoring of women with diabetes. It is a review of the impact of diabetes at different stages of a woman's life, how hormonal changes affect glycemic control, gestational diabetes, how diabetes affects the development of chronic complications in women and their consequences, the existing differences in the control of cardiovascular risk factors and the differential aspects by sex of the different families of drugs used in the treatment of diabetes.

Abstract
Objectives To determine the proportion of diabetic retinopathy (DR) among individuals with diabetes mellitus in the Gulf Cooperation Council (GCC) countries. Methods This study was executed in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. Online databases including Scopus, Web of Sciences, PubMed, Index Medicus for the eastern Mediterranean region, Medline, and ProQuest, were utilized to retrieve studies on the prevalence of DR in GCC countries that were conducted from 2003 to 2019. Results Twenty articles were included in the meta-analysis, involving 61 855 patients. The prevalence of DR was 20.5% (95% CI: 20.212-20.850). The highest prevalence rate was observed in Saudi Arabia (69.8%; 95% CI: 64.989-74.216) and the lowest in the UAE (6.0%; 95% CI: 2.780-11.084). There was a significant heterogeneity between the reviewed studies (p < 0.001). Conclusions The prevalence of DR was high in the GCC countries. Our findings provide crucial information for the public healthcare systems in these countries to actively educate the public and screen at-risk populations for undiagnosed cases of diabetes, detect early stages of retinopathy, and provide required care to minimize the number of untreated cases.

Time-trends in body mass index, and overweight and obesity as independent risk factors for diabetes angiopathy in young females with type 1 diabetes - A nationwide study in Sweden. Diabetes Res Clin Pract 2023; 204:110899. [PMID: 37678727 DOI: 10.1016/j.diabres.2023.110899] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 08/27/2023] [Accepted: 09/04/2023] [Indexed: 09/09/2023]
Abstract
AIMS To examine time-trends in BMI-distributions of young females with and without type 1 diabetes (T1D), with focus on the upper half of the distribution i.e., the median and above, and to explore if overweight and obesity independently increase risk of diabetes angiopathy. METHODS Population-based cohort study of 3,473 females with T1D, 16-35 years, identified in the Swedish National Diabetes Registers, January 2005 to October 2015, and 8,487 females from the background population. BMI-distributions were examined using kernel density estimates and quantile regression. Hazard ratios (HRs) and 95 % confidence intervals (CIs) for angiopathy in overweight/obese subjects were estimated with adjusted Cox regression. RESULTS The BMI-distribution in females with T1D was right shifted to that of the background population (p < 0.001). The 90th percentile and median BMI increased equally overtime in both groups, but females with T1D started from a higher baseline. In T1D, HRs were significantly increased for any angiopathy in individuals with obesity (adj HR 1.37 (CI 1.14-1.64)), and for retinopathy; adj HRs (CIs): overweight; 1.15 (1.02-1.29), obesity; 1.30 (1.08-1.56). CONCLUSIONS Females with T1D have increasing BMI overtime and are heavier than females without T1D. Overweight and obesity are by themselves risk factors for angiopathy.

Abstract
AIM The association between glycemic control and metabolic status is poorly defined in children and adolescents with T1D, besides being biologically plausible. We aimed to evaluate the association between glycemic control and body mass index (BMI), blood pressure (BP), and lipid profile in children and adolescents with T1D. METHODS Observational cross-sectional study including children and adolescents (5-18 years old) followed in our outpatient clinic with the diagnosis of T1D for at least a year. We used linear regression models (unadjusted and adjusted to sex and age) to evaluate the association between glycated hemoglobin (A1c) and time in range (TIR), several prespecified metabolic parameters, and prespecified demographic and clinical characteristics. We considered a p-value of <0.05 to be statistically significant. RESULTS A total of 144 patients were included, 51% of whom were female. The population had a mean age of 12.7±3.4 years old. We report a positive association between A1c and BMI, systolic and diastolic BP, total- and LDL-cholesterol and triglycerides. Females and patients diagnosed at a younger age presented with higher A1c values. There is a tendency for a negative association between TIR and the former parameters. Higher A1c levels and lower TIR were associated with higher glycemic variability and were treated with a higher basal insulin per Kg dose. CONCLUSION Our results support an important association between worse glycemic control and an unhealthier metabolic profile in children and adolescents with T1D. We can hypothesize that a good glycemic profile is needed to achieve good metabolic control at a young age.

Abstract
Objectives Individual studies in the Eastern Mediterranean Region (EMR) have shown the high prevalence of diabetic retinopathy. We conducted a meta-analysis to yield an estimate of the prevalence of diabetic (type 1 and 2) retinopathy in the EMR. Additionally, we explored its potential modulators. Methods Two-step screening of relevant articles published from 1 January 2000 to 13 December 2019 was carried out. An estimation of summary proportions, subgroup analysis, meta-regression, and publication bias assessment were performed. Results One hundred nine articles were included in the meta-analysis, involving 280,566 patients. The prevalence of diabetic retinopathy was 31% (95% confidence interval [CI] = 28, 33). The highest and lowest diabetic retinopathy prevalence rates were observed in low human development index (HDI) countries (63.6; 95% CI = 52.4, 74.0) and very high HDI countries 22.6 (95% CI = 20.5, 24.7), respectively. Conclusions The prevalence of diabetic retinopathy is high in the EMR. Our results provide important information for diverse healthcare surveillance systems in the EMR to implement the modifiable risk factors, diabetes screening to decrease undiagnosed diabetes, early detection of retinopathy, and proper diabetes care to decrease untreated diabetes.

Abstract
AIMS/HYPOTHESIS We hypothesised that adolescents with type 1 diabetes with a urinary albumin/creatinine ratio (ACR) in the upper tertile of the normal range (high ACR) are at greater risk of three-step diabetic retinopathy progression (3DR) independent of glycaemic control. METHODS This was a prospective observational study in 710 normoalbuminuric adolescents with type 1 diabetes from the non-intervention cohorts of the Adolescent Cardio-Renal Intervention Trial (AdDIT). Participants were classified as 'high ACR' or 'low ACR' (lowest and middle ACR tertiles) using baseline standardised log10 ACR. The primary outcome, 3DR, was determined from centrally graded, standardised two-field retinal photographs. 3DR risk was determined using multivariable Cox regression for the effect of high ACR, with HbA1c, BP, LDL-cholesterol and BMI as covariates; diabetes duration was the time-dependent variable. RESULTS At baseline mean ± SD age was 14.3 ± 1.6 years and mean ± SD diabetes duration was 7.2 ± 3.3 years. After a median of 3.2 years, 83/710 (12%) had developed 3DR. In multivariable analysis, high ACR (HR 2.1 [1.3, 3.3], p=0.001), higher mean IFCC HbA1c (HR 1.03 [1.01, 1.04], p=0.001) and higher baseline diastolic BP SD score (HR 1.43 [1.08, 1.89], p=0.01) were independently associated with 3DR risk. CONCLUSIONS/INTERPRETATION High ACR is associated with greater risk of 3DR in adolescents, providing a target for future intervention studies. TRIAL REGISTRATION isrctn.org ISRCTN91419926.

Abstract
PURPOSE Despite progress in type 1 diabetes (T1DM) therapy, diabetic retinopathy (DR) is still a common complication. We analysed predictors and prevalence of DR in patients with T1DM lasting 10 years or more. All of the patients were considered to be currently in excellent glycemic control and treated using modern therapies. METHODS Study included 384 (80.7% women) T1DM patients participating in the Program of Comprehensive Outpatient Specialist Care at the University Hospital in Krakow between the years 2014 and 2020. A retrospective analysis of medical records was conducted. RESULTS The patients were on average 34 ± 9.2 years old, had a BMI 25.0 ± 3.9 and a T1DM duration of 20.5 ± 7.9 years. The mean level of HbA1c throughout the follow-up (mean duration 4.9 ± 1.4 years) was 6.9 ± 1%. The group included 238 (62.0%) patients treated with insulin pumps and 99 (25.8%) on multiple daily injections, 47 (12.2%) used both methods; almost all patients were on insulin analogues. DR was confirmed in 150 (39.1%) patients, from which 109 (28.4%) were diagnosed de novo. Severe DR was occurred in just 31 cases (8.1%). In the multivariate logistic regression, independent risk factors for the presence of DR were T1DM duration (OR 1.13; 95% CI, 1.09-1.19), HbA1c level (OR 1.41; 95% CI, 1.08-1.84), LDL level (OR 1.79; 95% CI, 1.16-2.87), and the combined presence of non-DR micro- and macrovascular chronic complications (OR 1.86; 95% CI, 1.16-3.03). CONCLUSIONS In this highly-selected group of T1DM patients, mostly female, the prevalence of both DR at any stage and severe DR was lower than earlier reported results from other cohorts. Independent risk factors for the DR cohort did not differ from previously reported studies.

Abstract
PURPOSE OF REVIEW Diabetic retinopathy (DR) is a microvascular complication of diabetes mellitus and a major cause of vision loss worldwide. The purpose of this review is to provide an update on the prevalence of diabetic retinopathy in youth, discuss risk factors, and review recent advances in diabetic retinopathy screening. RECENT FINDINGS While DR has long been considered a microvascular complication, recent data suggests that retinal neurodegeneration may precede the vascular changes associated with DR. The prevalence of DR has decreased in type 1 diabetes (T1D) patients following the results of the Diabetes Control and Complications Trial and implementation of intensive insulin therapy, with prevalence ranging from 14-20% before the year 2000 to 3.7-6% after 2000. In contrast, the prevalence of diabetic retinopathy in pediatric type 2 diabetes (T2D) is higher, ranging from 9.1-50%. Risk factors for diabetic retinopathy are well established and include glycemic control, diabetes duration, hypertension, and hyperlipidemia, whereas diabetes technology use including insulin pumps and continuous glucose monitors has been shown to have protective effects. Screening for DR is recommended for youth with T1D once they are aged ≥ 11 years or puberty has started and diabetes duration of 3-5 years. Pediatric T2D patients are advised to undergo screening at or soon after diagnosis, and annually thereafter, due to the insidious nature of T2D. Recent advances in DR screening methods including point of care and artificial intelligence technology have increased access to DR screening, while being cost-saving to patients and cost-effective to healthcare systems. While the prevalence of diabetic retinopathy in youth with T1D has been declining over the last few decades, there has been a significant increase in the prevalence of DR in youth with T2D. Improving access to diabetic retinopathy screening using novel screening methods may help improve detection and early treatment of diabetic retinopathy.

Abstract
The global prevalence of autoimmune diseases is increasing. As a result, ocular complications, ranging from minor symptoms to sight-threatening scenarios, associated with autoimmune diseases have also risen. These ocular manifestations can result from the disease itself or treatments used to combat the primary autoimmune disease. This review provides detailed insights into the epidemiological factors affecting the increasing prevalence of ocular complications associated with several autoimmune disorders.

Abstract
PURPOSE To evaluate macular and peripapillary vascular changes by optical coherence tomography angiography (OCTA) in children with type 1 diabetes mellitus (T1DM) without diabetic retinopathy (DR). METHODS This study included 46 patients with T1DM and 46 age-sex matched healthy subjects. All participants were evaluated in terms of macular and optic disk parameters by using AngioVue. Foveal avascular zone (FAZ) area, macular and optic disk vessel density (VD) were analyzed. The correlation of these parameters with metabolic factors such as disease duration, mean hemoglobin A1c (HbA1c), insulin-like growth factor 1 (IGF-1) standard deviation score (SDS), homocysteine (Hcy) level, body mass index (BMI) SDS and daily insulin dose was also investigated in T1DM group. RESULTS No significant difference was found in FAZ area and optic disk radial peripapillary capillary (RPC) VD comparing diabetic and control groups. In all macular regions, VD was significantly lower in T1DM versus control group both in superficial capillary plexus (SCP) and deep capillary plexus (DCP). None of the metabolic parameters was correlated with FAZ area and optic disk RPC-VD. Vascular density in SCP was negatively correlated with mean HbA1c and positively correlated with IGF-1 SDS. Homocysteine level was negatively correlated with DCP-VD in all areas. CONCLUSION In children with T1DM without clinically apparent DR, VD in SCP and DCP was decreased and OCTA is a valuable imaging technique for detecting early vascular changes. The metabolic parameters such as mean HbA1c, IGF-1 SDS and Hcy affect the macular VD in diabetic children. TRIAL REGISTRATION NUMBER 2011-KAEK-2, 2021/4, Trial registration date: 02.04.2021.

[PMID: 34309688 PMCID: PMC8310903 DOI: 10.1007/s00125-021-05503-6] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2020] [Accepted: 03/31/2021] [Indexed: 12/16/2022]
Abstract
AIMS/HYPOTHESIS Tables reporting life expectancies by common risk factors are available for individuals with type 2 diabetes; however, there is currently no published equivalent for individuals with type 1 diabetes. We aimed to develop a life expectancy table using a recently published simulation model for individuals with type 1 diabetes. METHODS The simulation model was developed using data from a real-world population of patients with type 1 diabetes selected from the Swedish National Diabetes Register. The following six important risk factors were included in the life table: sex; age; current smoking status; BMI; eGFR; and HbA1c. For each of 1024 cells in the life expectancy table, a synthetic cohort containing 1000 individuals was created, with other risk factors assigned values representative of the real-world population. The simulations were executed for all synthetic cohorts and life expectancy for each cell was calculated as mean survival time of the individuals in the respective cohort. RESULTS There was a substantial variation in life expectancy across patients with different risk factor levels. Life expectancy of 20-year-old men varied from 29.3 years to 50.6 years, constituting a gap of 21.3 years between those with worst and best risk factor levels. In 20-year-old women, this gap was 18.9 years (life expectancy range 35.0-53.9 years). The variation in life expectancy was a function of the combination of risk factor values, with HbA1c and eGFR consistently showing a negative and positive correlation, respectively, with life expectancy at any level combination of other risk factors. Individuals with the lowest level (20 kg/m2) and highest level of BMI (35 kg/m2) had a lower life expectancy compared with those with a BMI of 25 kg/m2. Non-smokers and women had a higher life expectancy than smokers and men, respectively, with the difference in life expectancy ranging from 0.4 years to 2.7 years between non-smokers and smokers, and from 1.9 years to 5.9 years between women and men, depending on levels of other risk factors. CONCLUSIONS/INTERPRETATION The life expectancy table generated in this study shows a substantial variation in life expectancy across individuals with different modifiable risk factors. The table allows for rapid communications of risk in an easily understood format between healthcare professionals, health economists, researchers, policy makers and patients. Particularly, it supports clinicians in their discussion with patients about the benefits of improving risk factors.

Abstract
The aim of the study was to determine gender-specific risk factor sets which could influence optical coherence tomography (OCT) results in children with type 1 diabetes (T1D). MATERIAL AND METHODS 175 children with T1D without symptoms of diabetic retinopathy were enrolled, but 330 eyes were used for the final analysis (168 children, mean age 12.81 ± 3.63 years, diabetes duration 4.59 ± 3.71 years). The multivariate regression models for retinal thickness (foveal FT, and parafoveal PFT) and vascular densities (superficial and deep) were carried out separately for both genders using all metabolic and demographic parameters. RESULTS In the statistically significant multiple regression models for all analyzed OCT parameters for both genders, pH at the onset of diabetes were in existence, as well as for retinal thickness current HbA1c. Duration of continuous insulin infusion (CSII) was an important factor in all parameters, except PFT. For the girls, the most significant factors were daily insulin dose, uric acid, and triglycerides, but for the boys, it was serum creatinine, systolic pressure, and free thyroxine level. CONCLUSIONS We detected significant risk factors set for development of OCT parameters changes, and they were not identical for both genders. Current metabolic control, diabetic ketoacidosis at the disease onset, serum creatinine and longer use of CSII are the most important factors for retinal thickness and vessel densities in both genders in children with type 1 diabetes. For the girls, elements of metabolic syndrome (uric acid and triglycerides) and parameters of insulin amount were more pronounced.

Abstract
PURPOSE To evaluate the pragmatism and generalizability of randomized clinical trials (RCTs) on ranibizumab for diabetic macular edema and determine whether clinical outcomes would differ based on whether or not patients fulfill the eligibility criteria of these RCTs. METHODS Pragmatism and generalizability of three RCTs on ranibizumab for diabetic macular edema (DRCRnet Protocols I and T, and RESTORE) were rated using the PRECIS-2 tool. A cohort of consecutive patients with diabetic macular edema was assessed to determine whether clinical outcomes differed based on whether or not patients met the RCT eligibility criteria. Univariable and multivariable regression analyses, adjusted for baseline best-corrected visual acuity, central retinal thickness and number of injections received, were used. RESULTS All RCTs were rated as being more pragmatic than explanatory, with DRCRnet trials being the most pragmatic. Of the 216 eyes (176 patients) included in the cohort, 63% would have met eligibility criteria for Protocol T, 61% for Protocol I, and 56% for RESTORE. When adjusted for best-corrected visual acuity, central retinal thickness, and number of ranibizumab injections received, there were no statistically significant differences in best-corrected visual acuity or central retinal thickness found between "eligible" and "ineligible" patients. CONCLUSION Randomized clinical trials evaluating ranibizumab for diabetic macular edema were more pragmatic than explanatory. "Ineligible" patients still benefited from ranibizumab therapy.

Abstract
INTRODUCTION Type 1 diabetes mellitus (T1DM) is a chronic, autoimmune disease that is characterized by total absence of insulin production. Hypertension is a common comorbidity in T1DM with complex pathophysiology, while it is also a well-recognized risk factor for the development of cardiovascular disease (CVD), as well as other microvascular diabetic complications. AREAS COVERED The purpose of this review is to present the current definitions, epidemiological data and prevalence rates of hypertension in T1DM, as well as to describe current therapeutic options. EXPERT OPINION Hypertension affects around a third of the type 1 diabetic population, with higher prevalence rates in older individuals with longer disease duration. Although hypertension affects a substantial proportion of T1DM individuals, blood pressure control rates are disappointingly low. Alongside lifestyle modification, antihypertensive treatment should be initiated in those with blood pressure above 140/90 mmHg, with a systolic blood pressure target of 130 mmHg and lower, if tolerated. In those with established CVD or diabetic nephropathy, systolic blood pressure targets below 130 mmHg should be pursued. Initial pharmacotherapy should consist of a renin-angiotensin-aldosterone system inhibitor. There is an urgent need for good quality data regarding proper antihypertensive treatment initiation, optimal BP targets and optimal antihypertensive treatment for better clinical outcomes.

Abstract
OBJECTIVE Data on microvascular complications in children and adolescents with type 1 diabetes mellitus (T1DM) in Sudan are scarce. This study was aimed at determining the prevalence of diabetic nephropathy (DN) and retinopathy (DR) and their relationship to certain risk factors in children with T1DM attending the Sudan Childhood Diabetes Centre. Design and Methods. A clinic-based cross-sectional study of 100 patients with T1DM aged 10-18 years. Patients with disease duration exceeding 5 years if the onset of diabetes was prepubertal and 2 years if it was postpubertal were included. Relevant sociodemographic, clinical, and biochemical information was obtained. Blood pressure was measured. The patients were screened for DN and DR using urinary microalbumin estimation and fundus photography, respectively. RESULTS The frequency of microalbuminuria and diabetic retinopathy was 36% and 33%, respectively. Eleven percent had both retinopathy and microalbuminuria. Seven percent of the patients were found to be hypertensive. Patients with diabetic retinopathy had significantly higher HbA1c levels (p = 0.009) and longer diabetes duration (p = 0.02) than patients without retinopathy. Logistic regression showed that high HbA1c (odds ratio (OR) 0.83, confidence interval (CI) 0.68-1.00, p = 0.04), but not age, duration, ethnic group, BMI, blood pressure, and presence of nephropathy, was an independent risk factor for retinopathy. Likewise, high blood pressure (OR 6.89, CI 1.17-40.52, p = 0.03), but not age, duration, ethnic group, BMI, HbA1c, and presence of retinopathy, was a predictor for nephropathy. CONCLUSION High prevalence of incipient DN and early stages of DR were observed in this study. Longer diabetes duration and higher HbA1c were associated with the presence of diabetic retinopathy. High blood pressure was a risk factor for DN. So regular screening for these complications and optimization of glycemic control are needed.

Abstract
Rates of diabetic retinopathy (DR) and diabetic macular edema (DME), a common ocular complication of diabetes mellitus, are increasing worldwide. There is a substantial burden concerning the detection and management of this condition, particularly in low-resource settings, due to limitations such as the time, cost, and labor associated with current screening and treatment methods. Artificial intelligence (AI) is a modality of pattern recognition that has the potential to combat these limitations in a reliable and cost-effective way. This review explores the various applications of AI on the screening, management, and treatment of DR and DME. AI applications for detecting referable DR and DME have been the most thoroughly researched applications for this condition. While some studies exist using AI to stratify DR patients based on the risk of progression, predict treatment outcomes to anti-VEGF therapy, and explore the utilization of AI for clinical trials to develop new treatments for DR, further validation studies on larger datasets are warranted.

Abstract
Diabetes mellitus is becoming more prevalent and even with new advancements which improve glycaemic control, complications of diabetes are common. Vascular complications of diabetes include the microvascular complications: retinopathy, nephropathy, and peripheral and autonomic neuropathy. Macrovascular complications are also common in patients with diabetes and arguably more concerning as they confer a high mortality risk yet are sometimes under-treated. Risk factors for diabetes complications start to occur in childhood and adolescents and some youths may be diagnosed with complications before transition to adult care. This article discusses the prevalence, risk factors, screening, and treatment recommendations for vascular complications in children and adolescents with diabetes.

Abstract
The increasing prevalence of type 1 diabetes mellitus (DM) has made it necessary to have new markers for early detection of diabetic nephropathy. Renal resistive index (RI) by using renal Doppler can be a helpful tool in detecting functional alterations in renal hemodynamics. This study was conducted on 100 children and adolescents with type 1 DM. They were further subdivided into two equal subgroups: group 1 with type 1 DM and normo-albuminuria [urinary albumin excretion (UAE) <30 mg/24 hours], and group 2 with type 1 DM and hyper-albuminuria (increased UAE >30 mg/24 hours). There were 37 males (37%) and 63 females (63%); their mean ages were 13.6±2.53 (range, 10-19) years and mean disease duration was 8.867±2.260 (range, 5-13) years. Progressive increase in RI was significantly associated with increased disease duration more than 10 years, elevated serum HbA1c more than 7.5% and early pubertal stages. While not significantly related to sex, weight, height, blood pressure or serum lipid profile, diabetic micro-vascular complications (nephropathy and sensory neuropathy) were more prevalent among patients with RI more than 0.58. Renal RI could be a useful complementary test for the evaluation of functional alterations in renal hemodynamics in the early stages of diabetic nephropathy.

Abstract
INTRODUCTION Currently, all people with diabetes (PWD) aged 12 years and over in the UK are invited for screening for diabetic retinopathy (DR) annually. Resources are not increasing despite a 5% increase in the numbers of PWD nationwide each year. We describe the rationale, design and methodology for a randomised controlled trial (RCT) evaluating the safety, acceptability and cost-effectiveness of personalised variable-interval risk-based screening for DR. This is the first randomised trial of personalised screening for DR and the largest ophthalmic RCT in the UK. METHODS AND ANALYSIS PWD attending seven screening clinics in the Liverpool Diabetic Eye Screening Programme were recruited into a single site RCT with a 1:1 allocation to individualised risk-based variable-interval or annual screening intervals. A risk calculation engine developed for the trial estimates the probability that an individual will develop referable disease (screen positive DR) within the next 6, 12 or 24 months using demographic, retinopathy and systemic risk factor data from primary care and screening programme records. Dynamic, secure, real-time data connections have been developed. The primary outcome is attendance for follow-up screening. We will test for equivalence in attendance rates between the two arms. Secondary outcomes are rates and severity of DR, visual outcomes, cost-effectiveness and health-related quality of life. The required sample size was 4460 PWD. Recruitment is complete, and the trial is in follow-up. ETHICS AND DISSEMINATION Ethical approval was obtained from National Research Ethics Service Committee North West - Preston, reference 14/NW/0034. Results will be presented at international meetings and published in peer-reviewed journals. This pragmatic RCT will inform screening policy in the UK and elsewhere.

Abstract
Women have a higher incidence and prevalence of autoimmune diseases than men, and 85% or more patients of multiple autoimmune diseases are female. Women undergo sweeping endocrinological changes at least twice during their lifetime, puberty and menopause, with many women undergoing an additional transition: pregnancy, which may or may not be accompanied by breastfeeding. These endocrinological transitions exert significant effects on the immune system due to interactions between the hormonal milieu, innate, and adaptive immune systems as well as pro- and anti-inflammatory cytokines, and thereby modulate the susceptibility of women to autoimmune diseases. Conversely, pre-existing autoimmune diseases themselves impact endocrine transitions. Concentration-dependent effects of estrogen on the immune system; the role of progesterone, androgens, leptin, oxytocin, and prolactin; and the interplay between Th1 and Th2 immune responses together maintain a delicate balance between host defense, immunological tolerance and autoimmunity. In this review, multiple autoimmune diseases have been analyzed in the context of each of the three endocrinological transitions in women. We provide evidence from human epidemiological data and animal studies that endocrine transitions exert profound impact on the development of autoimmune diseases in women through complex mechanisms. Greater understanding of endocrine transitions and their role in autoimmune diseases could aid in prediction, prevention, and cures of these debilitating diseases in women.

Abstract
AIMS To evaluate our proposed multivariate approach to identify patients who will develop sight-threatening diabetic retinopathy (STDR) within a 1-year screen interval, and explore the impact of simple stratification rules on prediction. MATERIALS AND METHODS A 7-year dataset (2009-2016) from people with diabetes (PWD) was analysed using a novel multivariate longitudinal discriminant approach. Level of diabetic retinopathy, assessed from routine digital screening photographs of both eyes, was jointly modelled using clinical data collected over time. Simple stratification rules based on retinopathy level were also applied and compared with the multivariate discriminant approach. RESULTS Data from 13 103 PWD (49 520 screening episodes) were analysed. The multivariate approach accurately predicted whether patients developed STDR or not within 1 year from the time of prediction in 84.0% of patients (95% confidence interval [CI] 80.4-89.7), compared with 56.7% (95% CI 55.5-58.0) and 79.7% (95% CI 78.8-80.6) achieved by the two stratification rules. While the stratification rules detected up to 95.2% (95% CI 92.2-97.6) of the STDR cases (sensitivity) only 55.6% (95% CI 54.5-56.7) of patients who did not develop STDR were correctly identified (specificity), compared with 85.4% (95% CI 80.4-89.7%) and 84.0% (95% CI 80.7-87.6%), respectively, achieved by the multivariate risk model. CONCLUSIONS Accurate prediction of progression to STDR in PWD can be achieved using a multivariate risk model whilst also maintaining desirable specificity. While simple stratification rules can achieve good levels of sensitivity, the present study indicates that their lower specificity (high false-positive rate) would therefore necessitate a greater frequency of eye examinations.

Abstract
Type 1 and type 2 diabetes are increasing in prevalence and diabetes complications are common. Diabetes complications are rarely studied in youth, despite the potential onset in childhood. Microvascular complications of diabetes include retinopathy, diabetic kidney disease or nephropathy, and neuropathy that may be somatic or autonomic. Macrovascular disease is the leading cause of death in patients with type 1 diabetes. Strict glycaemic control will reduce microvascular and macrovascular complications; however, they may still manifest in youth. This article discusses the diagnosis and treatment of complications that arise from type 1 and type 2 diabetes mellitus in youth. Screening for complications is paramount as early intervention improves outcome. Screening should commence from 11 years of age depending on the duration of type 1 diabetes or at diagnosis for patients with type 2 diabetes. Diabetic retinopathy may require invasive treatment such as laser therapy or intravitreal antivascular endothelial growth factor therapy to prevent future blindness. Hypertension and albuminuria may herald diabetic nephropathy and require management with angiotensin converting enzyme (ACE) inhibition. In addition to hypertension, dyslipidaemia must be treated to reduce macrovascular complications. Interventional trials aimed at examining the treatment of diabetes complications in youth are few. Statins, ACE inhibitors and metformin have been successfully trialled in adolescents with type 1 diabetes with positive effects on lipid profile, microalbuminuria and measures of vascular health. Although relatively rare, complications do occur in youth and further research into effective treatment for diabetes complications, particularly therapeutics in children in addition to prevention strategies is required.

Abstract
The need for screening for retinopathy in patients with type 1 diabetes mellitus (T1DM) has been emphasised, but diagnostic delays were reported when screening was done at fixed intervals. To establish an individualised risk-prediction model to assist screening non-proliferative diabetic retinopathy (NPDR) in T1DM, we performed a retrospective cohort study enrolling participants in the Chang Gung Juvenile Diabetes Eye Study. There were 413 patients with 12 381 records analysed from 2005 to 2015. A time-dependent Cox proportional hazard analysis was used to evaluate the risks of NPDR development and a nomogram with risk-stratification indicators was established based on the results. During 97 months of follow-up, 43 of 413 patients (10.4%) developed NPDR. Male sex (HR: 0.4, 95% CI: 0.19–0.85), age 5–14 years at onset of T1DM (6.38, 2.41–16.87), duration of diabetes (1.57, 1.41–1.75), and hemoglobin A1c level (1.56, 1.35–1.80) were independently associated with NPDR. Using the nomogram offers a quick method in the clinical setting to interpret the risk of NPDR development. Based on its weighting, each of the independent factors is allocated a score, and the total points indicate the probabilities of NPDR occurring within 6 months, 1 year, and 3 years.

Abstract
AIM To examine the trajectory of small artery elasticity (SAE) and pulse pressure (PP) in people with Type 1 diabetes and non-diabetic controls across the lifespan, and explore associations with microvascular complications (CX+). METHODS This cross-sectional study included 477 Type 1 diabetes patients (188 with CX+, 289 without CX-) and 515 controls. Relationships between SAE and PP and age were evaluated using segmented linear regression. Logistic regression was used to assess the associations between microvascular complications (retinopathy and/or nephropathy) and SAE and PP. RESULTS SAE peaked significantly later among controls than diabetic patients CX- vs. CX+ (21.2 vs. 20.4 vs. 17.6 years respectively, p < 0.001). In adults, mean SAE was significantly lower in CX+ vs. CX- vs. controls (6.8 vs. 7.8 vs. 8.0 ml/mm Hg × 10; p < 0.0001), and mean PP was significantly higher in CX+ vs CX- and controls (60 vs. 55 vs. 53 mm Hg; p < 0.0001). CONCLUSION Type 1 diabetes CX+ subjects have an earlier peak and decline in SAE relative to CX- and controls, who did not differ. Lower SAE and higher PP were associated with increased odds of Type 1 diabetes complications in adults. These clinically applicable techniques demonstrate an association between accelerated vascular aging and vascular complications in diabetes.

Guided self-determination-young versus standard care in the treatment of young females with type 1 diabetes: study protocol for a multicentre randomized controlled trial. Trials 2017; 18:562.

Abstract
Background Female adolescents with type 1 diabetes mellitus (T1DM) have the most unsatisfactory glycaemic control of all age groups and report higher disease burden, poorer perceived health, and lower quality of life than their male counterparts. Females with T1DM face an excess risk of all-cause mortality compared with men with T1DM. New methods are needed to help and support young females with T1DM to manage their disease. A prerequisite for successful diabetes management is to offer individualized, person-centred care and support the patient’s own motivation. Guided self-determination (GSD) is a person-centred reflection and problem-solving method intended to support the patient’s own motivation in the daily care of her diabetes and help develop skills to manage difficulties in diabetes self-management. GSD has been shown to improve glycaemic control and decrease psychosocial stress in young women with T1DM. The method has been adapted for adolescents and their parents, termed GSD-young (GSD-Y). The aim of this study was to evaluate whether an intervention with GSD-Y in female adolescents with T1DM leads to improved glycaemic control, self-management, treatment satisfaction, perceived health and quality of life, fewer diabetes-related family conflicts, and improved psychosocial self-efficacy. Methods/design This is a parallel-group randomized controlled superiority trial with an allocation ratio of 1:1. One hundred female adolescents with T1DM, 15–20 years of age, and their parents (if < 18 years of age), will be included. The intervention group will receive seven individual GSD-Y education visits over 3 to 6 months. The control group will receive standard care including regular visits to the diabetes clinic. The primary outcome is level of glycaemic control, measured as glycosylated haemoglobin (HbA1c). Secondary outcomes include diabetes self-management, treatment satisfaction, perceived health and quality of life, diabetes-related family conflicts, and psychosocial self-efficacy. Data will be collected before randomization and at 6 and 12 months. Discussion Poor glycaemic control is common in female adolescents and young adults with T1DM. Long-standing hyperglycaemia increases the risks for severe complications and may also have an adverse impact on the outcome of future pregnancies. In this study, we want to evaluate if the GSD-Y method can be a useful tool in the treatment of female adolescents with T1DM. Trial registration Current controlled trials, ISRCTN57528404.

Abstract
OBJECTIVE To examine the relationship between diabetes distress and gender, and the association with glycemic control, social support, health behaviors, and socio-economic status. METHODS All adolescents, aged 15 to 18 years, in the national, pediatric diabetes registry SWEDIABKIDS with type 1 diabetes were invited to complete an online questionnaire. A total of 2112 teenagers were identified. RESULTS 453 complete responses were valid for analyses. Young women scored significantly higher on the distress-screening instrument DDS-2. Almost half of the female respondents exhibited moderate to severe diabetes distress-more than twice the proportion than among male respondents (44% vs 19%). Females reported twice as high scores on the fear of hypoglycemia scale (P < 0.0001) and had a higher HbA1c value than males (P < 0.0001). Gender was highly correlated with distress level even when controlling for multiple factors that may affect distress (parameterfemale = 0.4, P = 0.0003). Particular social problems were highly significant, that is, those who trust that their parents can handle their diabetes when necessary were significantly less distressed than others (P = 0.018). Higher HbA1c levels were associated with higher distress scores (P = 0.0005 [female], P = 0.0487 [male]). CONCLUSIONS Diabetes-related distress is a great burden for adolescents living with diabetes. Actively involved family and friends may reduce diabetes distress, but female adolescents appear to be particularly vulnerable and may need extra focus and support. Our findings indicate that pediatric diabetes teams working with teenagers must intensify the care during this vulnerable period of life in order to reduce the risk of both psychological and vascular complications in young adults.

Abstract
AIMS/HYPOTHESIS Retinal imaging enables non-invasive microvasculature assessment; however, only central retinal vessels have been studied in type 1 diabetes. Peripheral smaller vessels have a major haemodynamic role and may differ from central vessels in their response to the diabetic milieu. We hypothesise that diabetes has a greater impact on peripheral retinal vessels vs central vessels. METHODS Retinal photographs from adolescents (n = 736; age 12-20 years) with type 1 diabetes were graded (Singapore I Vessel Assessment) with vessel calibres measured in the 'central zone' as central retinal arteriolar and venular equivalents (CRAE and CRVE, respectively) and the 'extended zone' as mean width of arterioles and venules (MWa and MWv, respectively). Multivariable linear regression was used to explore associations between vessel calibres and HbA1c, diabetes duration, sex and BP. RESULTS Mean ± SD age was 14.1 ± 1.5 years, HbA1c was 8.5 ± 1.3% (69.4 ± 14.1 mmol/mol) and median diabetes duration was 4.9 years (interquartile range 3.1-7.6 years). Wider MWa was associated with HbA1c (β 0.01 [95% CI 0.004, 0.03]), longer diabetes duration (0.07 [0.02, 0.13]) and higher systolic BP (0.04 [0.02, 0.05]). MWv was associated with HbA1c (0.02 [0.009, 0.03]) and higher systolic BP (0.04 [0.03, 0.06]). CRAE was associated with longer diabetes duration (0.93 [0.58, 1.28]) and higher systolic BP (-0.28 [-0.37, -0.19]). CRVE was associated with longer diabetes duration (0.91 [0.42, 1.41]) and higher systolic BP (-0.20 [-0.33, -0.07]). Girls had wider vessels (for all four calibre measurements). CONCLUSIONS/INTERPRETATION In adolescents with type 1 diabetes, higher HbA1c is associated with adverse changes to peripheral smaller retinal vessels but not central vessels. The predictive value of retinal vascular imaging should be evaluated using longitudinal data.

Abstract
Introduction Type 1 Diabetes Mellitus (T1DM) is one of the important risk factor for cardiovascular disease. Endothelial dysfunction and increased Carotid Intima-Media Thickness (CIMT) result in cardiovascular complications. Vascular Cell Adhesion Molecule-1 (VCAM-1) and Intercellular Adhesion Molecule-1 (ICAM-1) are two adhesion molecules that are markers of early atherosclerosis and play a significant role in developing atherosclerosis. Aim To evaluate CIMT and its association with the levels of ICAM-1 and VCAM-1 in children and adolescents with T1DM. Materials and Methods In this descriptive, cross-sectional study conducted between April 2013 and September 2014, 29 children aged 7-20 years with T1DM for at least two years and 29 age and sex-matched, healthy individuals were evaluated. Plasma level of ICAM-1 and VCAM-1 was measured by ELISA, and CIMT via Doppler ultrasound was also assessed. The data were analysed by t-test and Pearson's correlation coefficient in SPSS 16.0 (p≤0.05). Results Independent t-test indicated that there is a significant difference in ICAM-1 level between the patients and controls (p<0.001). Further, CIMT was significantly higher in diabetic subject (p<0.001). CIMT was not significantly associated with the level of VCAM-1 and ICAM-1 in the patients (p>0.5). Conclusion ICAM-1 and VCAM-1 were not associated with CIMT but, CIMT and level of ICAM-1 were significantly, higher in diabetic patients, and therefore could be used as useful tools for identification of early atherosclerosis in children and adolescents with T1DM.

Abstract
AIMS To assess metabolic control in a paediatric T1D population in Spain and analyse the rate of severe acute decompensations and chronic complications. METHODS Data from patients treated at eight paediatric diabetes units with experienced diabetes teams between June and December 2014 were analysed in an observational prospective study. Variables included: age, sex, diabetes duration, number of follow-up visits/year, anthropometrical data, insulin treatment modalities, mean annual HbA1c and the prevalence of acute and chronic complications. SPSS statistics 21.0 was used. RESULTS A total of 853 patients (49.7% female) with a mean age of 12.1 ± 3.7 years were included. Anthropometric data were normal. Mean diabetes duration was 8 ± 3.4 years. Mean outpatient follow-up was 4.7 ± 0.04 visits/year. Twenty-five per cent were on continuous subcutaneous insulin infusion (CSII). Mean HbA1c was 7.3 ± 1% (56 ± 8 mmol/mol) and 66.6% had HbA1c < 7.5% (58 mmol/mol). HbA1c value correlated negatively with age at onset and positively with years of diabetes, number of visits/year and current age (F = 7.06; p = 0.01). Patients on CSII (n = 213) were younger, attended the outpatient clinic more frequently, were diagnosed earlier, had better metabolic control and had presented more severe hypoglycaemic episodes the previous year. The rate of severe decompensation (episodes/100 patients/year) was ketoacidosis 1.5 and severe hypoglycaemia 4.5. The prevalence of chronic complications was very low. CONCLUSIONS Our data describe the good compliance of paediatric T1D patients treated at eight paediatric units in Spain following international standards of metabolic control.

Abstract
Introduction The purpose of this study was to determine the prevalence of diabetic retinopathy in Samoa by piloting a retinal photography screening programme. Methods We performed a cross-sectional study of patients with diabetes who presented to the Tupua Tamasese Meaole eye clinic in Apia, Samoa, between May 2011 and September 2011. Study approval was granted by the National Health Service Board of Samoa, the Monash University Human Research Ethics Committee, and the study adhered to the Tenets of the Declaration of Helsinki. Following informed consent, data collection included patient demographics [age, area of residence (rural or urban)], type of diabetes, length of time since diagnosis, most recent random blood sugar and blood pressure levels. The subjects had three 45-degree retinal photographs taken in each eye with the Canon CR6-45NM camera. All gradable photographs were assessed for the presence of diabetic retinopathy or macular oedema using the International Clinical Diabetic Retinopathy Severity Scale and the International Clinical Diabetic Macular Oedema Severity scale, respectively. Results Two hundred and fourteen eyes from 107 subjects were examined during the study period, all of whom had type 2 diabetes mellitus. Diabetic retinopathy was present in 53.3% (114/214) of eyes, with 14.5% having proliferative retinopathy and 7.5% with severe non-proliferative retinopathy. Also, 25.2% (54/214) had some evidence of macular oedema with 11.7% (25/214) requiring treatment. A statistically significant relationship existed between the length of time since diagnosis and the severity of both retinopathy (p < 0.001) and macular oedema (p = 0.031). Blood pressure more than 150/85 mmHg was associated with higher levels of diabetic retinopathy (p = 0.03) and macular oedema (p = 0.02). Conclusion A comprehensive diabetic retinopathy screening programme is much needed in Samoa given the high prevalence of diabetic eye disease.

Abstract
Adolescence is a challenging period of life for any young person, and for those with Type 1 diabetes, physiological and psychological factors can result in a deterioration in glycaemic control. In young people with Type 1 diabetes, puberty may be an additional risk factor impacting on the lifetime risk for renal and cardiovascular complications. Our longitudinal studies have identified that increases in urinary albumin excretion through childhood are associated with the development of microalbuminuria and a generalized endotheliopathy linked to cardiovascular risk. Screening of participants recruited to the Adolescent type 1 Diabetes cardio-renal Intervention Trial (AdDIT) confirms that these early changes in albumin excretion are related to both diabetic nephropathy and cardiovascular risk; in part, independent of glycaemic control. Thus, as well as current attempts to improve glycaemic control through enhanced targeted insulin delivery, pumps, sensors and closed loop, we have explored the role of angiotensin-converting enzyme inhibitors and statins in providing cardio-renal protection during adolescence.

Abstract
Diabetic retinopathy (DR), one of the leading causes of preventable blindness, is associated with many systemic factors that contribute to the development and progression of this microvascular complication of diabetes. While the duration of diabetes is the major risk factor for the development of DR, the main modifiable systemic risk factors for development and progression of DR are hyperglycemia, hypertension, and dyslipidemia. This review article looks at the evidence that control of these systemic factors has significant benefits in delaying the onset and progression of DR.

Abstract
BACKGROUND Complications of hypertension are particularly common in people of African descent but previous reports had suggested rarity of hypertensive retinopathy in black Africans. We evaluated retinal changes among Nigerian hypertensive patients and determined their relationship with renal function. METHODS Consecutive Hypertensive patients who were ≥18 years were selected for the study. Socio-demographic characteristics, anthropometric parameters and blood pressure were measured. All patients had ophthalmoscopic examination and retinal changes were graded according to Keith-Wegener's classification. Blood samples were taken for blood urea nitrogen, lipids and C-reactive protein; and urine was collected for creatinine and microalbuminuria. Serum creatinine was determined using modified Jaffe method and estimated glomerular filtration (eGFR) was calculated using MDRD equation: 186 × (Creatinine/88.4)-1.154 × (Age)-0.203 × (0.742 if female) × (1.210 if black). RESULTS Of the 240 patients studied, 187 (78 %) had one form of retinopathy or the other. While 85 (35.4 %) patients had grade 1 retinopathy, 87 (36.3 %) had grade 2, 13 (5.4 %) had grade 3 and 2 (0.83 %) had grade 4 respectively. Comparison of patients with and without retinopathy showed that, the former were older (p = 0.001) and had longer duration of hypertension (p = 0.001). Similarly, hypertensive patients with retinopathy had higher total cholesterol and low density lipoprotein cholesterol (p = 0.017, p = 0.041 respectively). However, eGFR was lower in individuals with retinopathy (46.2 ml/min/1.73) than those with normal retinal (55.9 ml/min/1.73) findings, p = 0.019. Multi-variable adjusted odds ratios showed increased probability of retinopathy with age (odds ratio-1.08, p = 0.001) and body mass index (odds ratio-1.20, p = 0.013). CONCLUSIONS Hypertensive retinopathy is a common clinical finding among hypertensive Nigerians and may occur pari passu with renal damage as consequences of long standing hypertension.

Abstract
PURPOSE To customize clinical practice guidelines (CPGs) for management of diabetic retinopathy (DR) in the Iranian population. METHODS Three DR CPGs (The Royal College of Ophthalmologists 2013, American Academy of Ophthalmology [Preferred Practice Pattern 2012], and Australian Diabetes Society 2008) were selected from the literature using the AGREE tool. Clinical questions were designed and summarized into four tables by the customization team. The components of the clinical questions along with pertinent recommendations extracted from the above-mentioned CPGs; details of the supporting articles and their levels of evidence; clinical recommendations considering clinical benefits, cost and side effects; and revised recommendations based on customization capability (applicability, acceptability, external validity) were recorded in 4 tables, respectively. Customized recommendations were sent to the faculty members of all universities across the country to score the recommendations from 1 to 9. RESULTS Agreed recommendations were accepted as the final recommendations while the non-agreed ones were approved after revision. Eventually, 29 customized recommendations under three major categories consisting of screening, diagnosis and treatment of DR were developed along with their sources and levels of evidence. CONCLUSION This customized CPGs for management of DR can be used to standardize the referral pathway, diagnosis and treatment of patients with diabetic retinopathy.

Abstract
AIMS To evaluate relationships between early alterations in blood pressure and the progression of microvascular complications of diabetes in clinically-normotensive patients with type 1 diabetes (T1DM). METHODS In a prospective observational study of 85 normotensive T1DM patients without microalbuminuria, blood pressure (BP) was monitored over 24h using the ambulatory blood pressure monitoring (ABPM) system at baseline and 7years later. Development or progression of microalbuminuria, retinopathy and hypertension was evaluated. RESULTS Initially, 20 patients (24%) were diagnosed with masked hypertension and 31 (37%) with non-dipper pattern as the only pathological findings. At 7years: 1) twenty-seven patients (32%) had progression of retinopathy related to the nocturnal diastolic blood pressure (BPD) (OR:1.122; p=0.034) and final non-dipper pattern (OR:5.857; p=0.005); 2) seven patients (10%) developed microalbuminuria for which nocturnal systolic blood pressure (BPS) was a risk factor (OR:1.129; p=0.007); 3) five of the normotensive patients (9%) progressed to hypertension; historic HbA1c (OR:2.767; p=0.046) and nocturnal BPD (OR:1.243; p=0.046) being the related risk factors. BPD level ≥65mmHg was associated with an increase in progression of retinopathy and hypertension. CONCLUSIONS In T1DM patients there is an elevated prevalence of BP alterations, detected using ABPM. Alterations in nocturnal BP predispose to development/progression of microvascular complications and overt hypertension.

Abstract
AimTo assess whether the current starting age of 12 is suitable for diabetic retinopathy (DR) screening and whether diabetes duration should be taken into account when deciding at what age to start screening patients.Materials and methodsA retrospective analysis of 143 patients aged 12 years or younger who attended diabetic eye screening for the first time in the Birmingham, Solihull and Black Country Diabetic Eye Screening Programme was performed.ResultsThe mean age of the patients was 10.7 (7-12) years with 73 out of 143 aged below 12 years and 70 were 12 years of age. 98% had type 1 diabetes and mean diabetes duration was 5 (1 month-11 years) years. For those younger than 12 years, 7/73 (9.6%) had background DR (BDR), of these mean diabetes duration was 7 years (6-8). The youngest patient to present with DR was aged 8 years. In those aged 12 years, 5/70 (7.1%) had BDR; of these mean diabetes duration was 8 years (6-11). No patient developed DR before 6 years duration in either group.ConclusionsThe results show that no patient younger than the age of 12 had sight-threatening DR (STDR), but BDR was identified. Based on the current mission statement of the Diabetic Eye Screening Programme to identify STDR, 12 years of age is confirmed as the right age to start screening, but if it is important to diabetic management to identify first development of DR, then screening should begin after 6 years of diabetes diagnosis.

Abstract
BACKGROUND Diabetic retinopathy (DR) is linked to increased risk of cardiovascular (CV) disease. However, the effect size of the association was not consistent. In this study, we performed a systematic review and meta-analysis of available cohort studies to determine the association between DR and CV disease, and to investigate the factors that influence the association. METHODS Terms related to DR and CV disease were searched from MEDLINE and EMBASE database. High-quality articles (Newcastle-Ottawa scales above 6) conducted in cohort studies reporting the association between DR and CV disease were identified. Study-specific estimates were pooled using random effects with inverse variance meta-analysis. Subgroup analysis was performed according to diabetes types. Heterogeneity of included studies was assessed using the I(2) test. The cause of the heterogeneity was examined using metaregression analyses. RESULTS A total of 13 studies representing 17,611 patients without CV disease at baseline were included. At follow-up, there were 1457 CV disease-related incidences. Overall, DR was associated with increased risk of CV disease (relative risk [RR]: 2.42, 95% confidence interval [CI]: 1.77-3.31) in diabetes. Specifically, the RR was 3.59 (95% CI: 1.79-7.20) for type 1 diabetes and 1.81 (95% CI: 1.47-2.23) for type 2 diabetes. Significant heterogeneity was found in studies with type 1 diabetes. Metaregression analysis showed that baseline systolic blood pressure was a key factor leading to the heterogeneity. CONCLUSION In conclusion, DR is significantly associated with CV disease incidence and CV disease-related mortality in diabetes. Patients with DR may need more intensive management to control future CV disease attacks.

Abstract
AIM To audit levels of diabetes-related eye disease in Type 1 diabetes mellitus (T1DM) patients in northwest Ethiopia. In particular to establish whether, despite identical clinical goals, major differences between the physically demanding life-style of rural subsistence farmers and the sedentary life-style of urban dwellers would influence the prevalence of diabetes-related eye complications. METHODS A robust infrastructure for chronic disease management that comprehensively includes all rural dwellers was a pre-requisite for the investigation. A total of 544 T1DM were examined, representing 80% of all T1DM patients under regular review at both the urban and rural clinics and representative of patient age and gender (62.1% male, 37.9% female) of T1DM patients from this region; all were supervised by the same clinical team. Eye examinations were performed for visual acuity, cataract and retinal changes (retinal photography). HbA1c levels and the presence or absence of hypertension were recorded. RESULTS/CONCLUSIONS Urban and rural groups had similar prevalences of severe visual impairment/blindness (7.0% urban, 5.2% rural) and cataract (7.3% urban, 7.1% rural). By contrast, urban dwellers had a significantly higher prevalence of retinopathy compared to rural patients, 16.1% and 5.0%, respectively (OR 2.9, p<0.02, after adjustment for duration, age, gender and hypertension). There was a 3-fold greater prevalence of hypertension in urban patients, whereas HbA1c levels were similar in the two groups. Since diabetic retinopathy is closely associated with microvascular disease and endothelial dysfunction, the possible influences of hypertension to increase and of sustained physical activity to reduce endothelial dysfunction are discussed.

Abstract
PURPOSE The purpose of this study was to examine the relationship between metabolic and inflammatory markers in patients with diabetic retinopathy (DR). METHODS 208 adult patients with type 2 diabetes participated in this study and were categorized into (1) mild nonproliferative diabetic retinopathy (NPDR) without clinically significant macular edema (CSME), (2) NPDR with CSME, (3) proliferative diabetic retinopathy (PDR) without CSME, and (4) PDR with CSME. Variable serum metabolic markers were assessed using immunoassays. Multinomial logistic regression analysis was performed. RESULTS Diabetes duration and hypertension are the most significant risk factors for DR. Serum Apo-B and Apo-B/Apo-A ratio were the most significant metabolic risk factors for PDR and CSME. For every 0.1 g/L increase in Apo-B concentration, the risk of PDR and CSME increased by about 1.20 times. We also found that 10 pg/mL increase in serum TNF-α was associated with approximately 2-fold risk of PDR/CSME while an increase by 100 pg/mL in serum VEGF concentration correlated with CSME. CONCLUSIONS In conclusion, it seems that there is a link between metabolic and inflammatory markers. Apo-B/Apo-A ratio should be evaluated as a reliable risk factor for PDR and CSME, while the role of increased systemic TNF-α and VEGF should be explored in CSME.

Abstract
Diabetes mellitus (DM) has assumed epidemic proportions and as a consequence, diabetic retinopathy is expected to be a major societal problem across the world. Diabetic retinopathy (DR) affects the vision by way of proliferative disease that results in vitreous hemorrhage and traction retinal detachment or by way of diabetic maculopathy (DME). The present-day management of diabetic retinopathy revolves around screening the diabetics for evidence of retinopathy and treating the retinopathy with laser photocoagulation. DME is treated with laser photocoagulation and/or intra- vitreal injection of anti-vascular endothelial growth factor (VEGF) agents or steroids. Laser remains the mainstay of treatment and is potentially destructive. Systemic management aims at preventing or delaying the onset of retinopathy; reversing the early retinopathy; or delaying the progression of established retinopathy. Evidence from multiple studies has confirmed the protective role of rigid control of blood glucose and blood pressure. The evidence for lipid control versus maculopathy was less definitive. However, the use of fenofibrates (originally used for lowering serum lipids) has shown a benefit on both proliferative disease and maculopathy outside their lipid-lowering effect. Other drugs being tried are the Protein Kinase C (PKC) inhibitors, other peroxisome proliferator-activated receptors (PPAR) agonists, Forsoklin (which binds GLUT 1 receptor), minocycline (for its anti inflammatory effect), and Celecoxib (Cox-2 inhibitor).

Abstract
The diagnosis and treatment of diabetic retinopathy (DR) in young adults have significantly improved in recent years. Research methods have widened significantly, for example, by introducing spectral optical tomography of the eye. Invasive diagnostics, for example, fluorescein angiography, are done less frequently. The early introduction of an insulin pump to improve the administration of insulin is likely to delay the development of diabetic retinopathy, which is particularly important for young patients with type 1 diabetes mellitus (T1DM). The first years of diabetes occurring during childhood and youth are the most appropriate to introduce proper therapeutic intervention before any irreversible changes in the eyes appear. The treatment of DR includes increased metabolic control, laserotherapy, pharmacological treatment (antiangiogenic and anti-inflammatory treatment, enzymatic vitreolysis, and intravitreal injections), and surgery. This paper summarizes the up-to-date developments in the diagnostics and treatment of DR. In the literature search, authors used online databases, PubMed, and clinitrials.gov and browsed through individual ophthalmology journals, books, and leading pharmaceutical company websites.

Abstract
Much is written about how difficult it is to deal with diabetes during adolescence, and rightly so. Less is understood as to how puberty may be an accelerator of vascular complications. With the increase in childhood diabetes, complication risks need to be revisited in relation to puberty and the secular increase in adiposity. Recent data suggest greater risk for severe vascular complications in those with diabetes during puberty, compared with young people who develop diabetes after puberty. It is also widely recognized that higher hemoglobin A1c (HbA1c) results are often seen during the pubertal period. This article will review complication outcomes in relation to puberty and examine mechanisms by which puberty may modify risk above glycemic exposure, and possible gender disparities in the risk of complications in the adolescent period.

[PMID: 23819888 PMCID: PMC3729714 DOI: 10.1186/1741-7015-11-157] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2013] [Accepted: 06/04/2013] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Sub-Saharan Africa faces an epidemic of diabetes. Diabetes causes significant morbidity including visual loss from diabetic retinopathy, which is largely preventable. In this resource-poor setting, health systems are poorly organized to deliver chronic care with multiple system involvement. The specific skills and resources needed to manage diabetic retinopathy are scarce. The costs of inaction for individuals, communities and countries are likely to be high. DISCUSSION Screening for and treatment of diabetic retinopathy have been shown to be effective, and cost-effective, in resource-rich settings. In sub-Saharan Africa, clinical services for diabetes need to be expanded with the provision of effective, integrated care, including case-finding and management of diabetic retinopathy. This should be underpinned by a high quality evidence base accounting for differences in diabetes types, resources, patients and society in Africa. Research must address the epidemiology of diabetic retinopathy in Africa, strategies for disease detection and management with laser treatment, and include health economic analyses. Models of care tailored to the local geographic and social context are most likely to be cost effective, and should draw on experience and expertise from other continents. Research into diabetic retinopathy in Africa can drive the political agenda for service development and enable informed prioritization of available health funding at a national level. Effective interventions need to be implemented in the near future to avert a large burden of visual loss from diabetic retinopathy in the continent. SUMMARY An increase in visual loss from diabetic retinopathy is inevitable as the diabetes epidemic emerges in sub-Saharan Africa. This could be minimized by the provision of case-finding and laser treatment, but how to do this most effectively in the regional context is not known. Research into the epidemiology, case-finding and laser treatment of diabetic retinopathy in sub-Saharan Africa will highlight a poorly met need, as well as guide the development of services for that need as it expands.
