The effectiveness of a community-based, type 2 diabetes prevention programme on health-related quality of life. The DE-PLAN study

Background and aims

The DE-PLAN was a European multicenter study, with the primary objective of testing whether a community-based lifestyle modification programme could serve as a means of primary prevention for type 2 diabetes (T2D) in high-risk individuals (based on the FINDRISC questionnaire). The aim of this study was to examine the impact of a 1-year community-based lifestyle intervention on health-related quality of life (HRQOL) in individuals from four participating European centers (Athens, Barcelona, Krakow, Kaunas), through a post-hoc analysis.

Materials and methods

Each center was allowed to implement different intervention strategies specifically tailored to the needs of their corresponding population sample. Before and after the intervention, participants underwent clinical evaluation, anthropometric measurements, an oral glucose tolerance test and lipid profile measurements. Health-related quality of life was assessed using the validated HRQOL-15D questionnaire. A difference of ±0.015 in the 15D questionnaire score was set as the threshold of clinically meaningful change.

Results

Data from 786 participants (67% females, mean age 59.7±9.4 years, BMI 31.5±4.5 kg/m²) with complete data regarding the HRQOL were analyzed (Athens: 104, Barcelona: 434, Krakow: 175, Kaunas: 70). After 1 year, a significant overall improvement in HRQOL was shown, as depicted by a change of 15D score from baseline value (0.88±0.9) to post-intervention (0.90±0.87, P<0.001), achieving the threshold of clinically meaningful change. A significant weight reduction was also observed (-0.8±4.0 kg, P<0.001). In multivariate analysis, improvement in HRQOL was independently associated with lower 15D score at baseline (P<0.001) and self-reported increase in overall exercise time (P<0.001) as assessed through specifically designed trial questionnaires.

Conclusion

A community-based lifestyle intervention programme aiming at T2D prevention, applied on a heterogeneous population and with varied methods, was shown to improve overall health-related quality of life to a clinically meaningful degree.

The Association of CEP135 rs4865047 and NPY2R rs1902491 Single Nucleotide Polymorphisms (SNPs) with Rapid Progression of Proliferative Diabetic Retinopathy in Patients with Type 1 Diabetes Mellitus

Background

Diabetic retinopathy has a varied prevalence, severity, and rate of progression. The aim of this study was to determine whether the single nucleotide polymorphisms (SNPs) of the gene encoding a 135-kD centrosomal protein CEP135 rs4865047 and the gene encoding the type 2 NPY protein NPY2R rs1902491 were associated with the development of rapidly progressive proliferative diabetic retinopathy in patients with type 1 diabetes mellitus.

Material/Methods

Patients with rapidly progressive proliferative diabetic retinopathy (n=48) were included in the study group. The control group (n=84) consisted of diabetes mellitus patients who had no proliferative diabetic retinopathy up to 15 years of diabetes duration. The reference group (n=90) included non-diabetic individuals who matched the study group by age and gender. The SNPs in the three groups were analyzed using real-time polymerase chain reaction (PCR) amplification.

Results

The analysis of the distribution of genotypes in CEP135 rs4865047 and NPY2R rs1902491 detected significant differences only in the single nucleotide polymorphism rs4865047 genotype between the case and control group in comparison to the reference group. The co-dominant model showed that CEP135 rs4865047 was significantly associated with patients with rapidly progressive proliferative diabetic retinopathy (OR 7.2, 95% CI, 2.28–22.74, p=0.001). No significant association was found for the NPY2R SNP rs1902491 genotype.

Conclusions

Our study reports a significant association of the CEP135 single nucleotide polymorphism rs4865047 genotype with rapidly progressive proliferative diabetic retinopathy and the control group. No significant association was found of the NPY2R single nucleotide polymorphism rs1902491 genotype.

Methimazole-induced liver injury overshadowed by methylprednisolone pulse therapy: Case report

RATIONALE

Treatment choices are limited, when deciding how to manage thyrotoxicosis and moderate to severe Graves ophthalmopathy (GO) with suspected optic nerve damage in patients with elevated liver transaminase levels. The situation become even more complicated, if methimazole induced hepatotoxicity is suspected and intravenous methylprednisolone is co-administrated.

PATIENT CONCERNS

A 74-year-old woman presented with spontaneous retro-bulbar pain, eyelid swelling and inconstant diplopia.

DIAGNOSES

Thyrotoxicosis and severe GO with suspected optic nerve damage and drug induced liver injury (DILI).

INTERVENTIONS

Intravenous methylprednisolone pulse therapy was administered to treat GO and methimazole was continued for thyrotoxicosis. Dose of methimazole was reduced after exclusion of concurrent infection and active liver disease.

OUTCOMES

The GO symptoms (eyelid swelling, sight loss, proptosis, retro-bulbar pain, diplopia) markedly decreased after the treatment course. Liver transaminases spontaneously returned to normal ranges and remained normal during the next 12 months until the Graves' disease until the treatment was completed.

LESSONS

1. The interaction of methimazole and methylprednisolone may result in DILI. 2. In a patient without concomitant liver diseases MP can be continued if the methimazole dose is reduced if no other treatment options are available.

Retrospective analysis of age-adjusted body mass index among pre-pregnant women in the Lithuanian urban area during three decades

BACKGROUND

The prevalence of maternal obesity at the beginning of pregnancy is increasing. However, there are some studies reporting the stabilisation of obesity epidemic or even the downward trend in the general population.

OBJECTIVE

To determine the prevalence of overweight and obesity in Lithuanian pre-pregnant women during 3 decades.

METHODS

This observational retrospective study included a sample of 2827, women aged 18-44 years who gave birth in 1987-1989, 1996-1997 and 2007-2010: 861 (30.5%), 995 (35.2%) and 971 (34.3%), respectively. All women were divided into groups by body mass index (BMI) calculated from self-reported weight and height, and age reported during the first antenatal visit. Quantitative parametric variables were expressed as mean and SD; qualitative variables, as absolute numbers (n) and percentage (%). For parametric data, analysis of variance (ANOVA) was used. Differences were considered statistically significant at p<0.05.

RESULTS

The prevalence of overweight and obesity among women aged 18-24 years decreased from 20.9% in 1987-1989 to 9.5% in 1996-1997 but increased to 15.7% in 2007-2010; among women aged 25-34 years, decreased from 35.5% in 1987-1989 to 23% in 1996-1997 and to 22.4% in 2007-2010; and among women aged 35-44 years decreased from 64.9% in 1987-1989 to 34% in 1996-1997 but increased to 45.3% in 2007-2010. BMI increased with an increasing age (r=0.254, p<0.05). Analysis by separate periods (1987-1989, 1996-1997 and 2007-2010) revealed a positive correlation between BMI and age at the first antenatal visit in all periods (r=0.325, p<0.01; r=0.266, p<0.01; and r=0.210, p<0.01, respectively).

CONCLUSIONS

The prevalence of overweight and obesity among pre-pregnant women tended to decrease in the Lithuanian urban area during 3 decades. A slight increase in overweight and obesity documented in 2007-2010 compared with 1996-1997 most likely was caused by older maternal age.

Quality indicators for the prevention of type 2 diabetes in Europe--IMAGE

BACKGROUND

The marked increase of type 2 diabetes necessitates active development and implementation of efficient prevention programs. A European level action has been taken by launching the IMAGE project to unify and improve the various prevention management concepts, which currently exist within the EU. This report describes the background and the methods used in the development of the IMAGE project quality indicators for diabetes primary prevention programs. It is targeted to the persons responsible for diabetes prevention at different levels of the health care systems.

METHODS

Development of the quality indicators was conducted by a group of specialists representing different professional groups from several European countries. Indicators and measurement recommendations were produced by the expert group in consensus meetings and further developed by combining evidence and expert opinion.

RESULTS

The quality indicators were developed for different prevention strategies: population level prevention strategy, screening for high risk, and high risk prevention strategy. Totally, 22 quality indicators were generated. They constitute the minimum level of quality assurance recommended for diabetes prevention programs. In addition, 20 scientific evaluation indicators with measurement standards were produced. These micro level indicators describe measurements, which should be used if evaluation, reporting, and scientific analysis are planned.

CONCLUSIONS

We hope that these quality tools together with the IMAGE guidelines will provide a useful tool for improving the quality of diabetes prevention in Europe and make different prevention approaches comparable.

Take action to prevent diabetes--the IMAGE toolkit for the prevention of type 2 diabetes in Europe

When we ask people what they value most, health is usually top of the list. While effective care is available for many chronic diseases, the fact remains that for the patient, the tax payer and the whole of society: prevention is better than cure. Diabetes and its complications are a serious threat to the survival and well-being of an increasing number of people. It is predicted that one in ten Europeans aged 20-79 will have developed diabetes by 2030. Once a disease of old age, diabetes is now common among adults of all ages and is beginning to affect adolescents and even children. Diabetes accounts for up to 18 % of total healthcare expenditure in Europe. The good news is that diabetes is preventable. Compelling evidence shows that the onset of diabetes can be prevented or delayed greatly in individuals at high risk (people with impaired glucose regulation). Clinical research has shown a reduction in risk of developing diabetes of over 50 % following relatively modest changes in lifestyle that include adopting a healthy diet, increasing physical activity, and maintaining a healthy body weight. These results have since been reproduced in real-world prevention programmes. Even a delay of a few years in the progression to diabetes is expected to reduce diabetes-related complications, such as heart, kidney and eye disease and, consequently, to reduce the cost to society. A comprehensive approach to diabetes prevention should combine population based primary prevention with programmes targeted at those who are at high risk. This approach should take account of the local circumstances and diversity within modern society (e.g. social inequalities). The challenge goes beyond the healthcare system. We need to encourage collaboration across many different sectors: education providers, non-governmental organisations, the food industry, the media, urban planners and politicians all have a very important role to play. Small changes in lifestyle will bring big changes in health. Through joint efforts, more people will be reached. The time to act is now.

A European evidence-based guideline for the prevention of type 2 diabetes

BACKGROUND

The prevalence and socioeconomic burden of type 2 diabetes (T2DM) and associated co-morbidities are rising worldwide.

AIMS

This guideline provides evidence-based recommendations for preventing T2DM.

METHODS

A European multidisciplinary consortium systematically reviewed the evidence on the effectiveness of screening and interventions for T2DM prevention using SIGN criteria.

RESULTS

Obesity and sedentary lifestyle are the main modifiable risk factors. Age and ethnicity are non-modifiable risk factors. Case-finding should follow a step-wise procedure using risk questionnaires and oral glucose tolerance testing. Persons with impaired glucose tolerance and/or fasting glucose are at high-risk and should be prioritized for intensive intervention. Interventions supporting lifestyle changes delay the onset of T2DM in high-risk adults (number-needed-to-treat: 6.4 over 1.8-4.6 years). These should be supported by inter-sectoral strategies that create health promoting environments. Sustained body weight reduction by >or= 5 % lowers risk. Currently metformin, acarbose and orlistat can be considered as second-line prevention options. The population approach should use organized measures to raise awareness and change lifestyle with specific approaches for adolescents, minorities and disadvantaged people. Interventions promoting lifestyle changes are more effective if they target both diet and physical activity, mobilize social support, involve the planned use of established behaviour change techniques, and provide frequent contacts. Cost-effectiveness analysis should take a societal perspective.

CONCLUSIONS

Prevention using lifestyle modifications in high-risk individuals is cost-effective and should be embedded in evaluated models of care. Effective prevention plans are predicated upon sustained government initiatives comprising advocacy, community support, fiscal and legislative changes, private sector engagement and continuous media communication.

Predicting outcome of treatment with radiotherapy in endocrine ophthalmopathy

OBJECTIVE

To evaluate if the concentration of C-reactive protein and the level of antibodies to thyrotropin receptors might predict the outcome of retrobulbar irradiation in patients with endocrine ophthalmopathy.

MATERIAL AND METHODS

Patients with moderate endocrine ophthalmopathy received orbital radiotherapy. The overall severity of endocrine ophthalmopathy was assessed using the total eye score based on the NOSPECS classification before the treatment and 6 months later. Treatment outcome was evaluated using major and minor criteria recommended by L. Bartalena 6 months after the treatment. Patients who improved in at least one major or in two or more minor criteria were considered responders. Patients in whom no changes occurred or who responded in only one minor criterion or eye status worsened were classified as nonresponders. The active disease was considered present in a patient who responded successfully to retrobulbar irradiation, and the inactive one when a patient did not respond.

RESULTS

The level of antibodies to thyrotropin receptors in responders was 24.0 IU/L (range 2.0-405.0 IU/L) and in nonresponders 23.0 IU/L (range 2.0-405.0 IU/L); P=0.72. C-reactive protein levels in responders and nonresponders were 0.1 mg/L (range 0.1-3.1 mg/L) and 0.1 mg/L (range 0.1-1.5 mg/L), respectively; P=0.92. Although responders and nonresponders differed by proptosis, the severity of endocrine ophthalmopathy, and clinical activity score, but according to the binary logistic regression model, only the clinical activity score could give additional information on the prediction of the treatment outcome. If clinical activity score increased by 1, odds ratio for successful treatment outcome increased 2.4 times.

CONCLUSIONS

1) At the baseline of radiotherapy, the level of antibodies to thyrotropin receptors and concentration of C-reactive protein in responders did not differ from nonresponders; 2) Responders did not differ from nonresponders to radiotherapy by age, gender, duration of endocrine ophthalmopathy and thyroid disease; 3) The pretreatment clinical activity score, total eye score, proptosis of the responders were higher.

Mood and anxiety disorders in women with treated hyperthyroidism and ophthalmopathy caused by Graves' disease

OBJECTIVE

To evaluate the prevalence of mood and anxiety disorders in women with treated hyperthyroidism caused by Graves' disease and to compare them with the prevalence of such findings in women without past or present thyroid disease.

METHODS

Thirty inpatient women with treated hyperthyroidism and ophthalmopathy caused by Graves' disease and 45 women hospitalized for treatment of gynecologic disorders such as abnormal vaginal bleeding, benign tumors or infertility were evaluated for the prevalence of mood and anxiety diagnoses using a standard Mini-International Neuropsychiatric Interview and for mood and anxiety ratings using the Profile of Mood States (POMS). At the time of assessment, it was discovered that 14 of 30 women with treated hyperthyroidism caused by Graves' disease were still hyperthyroid, while 16 women were euthyroid.

RESULTS

Significantly greater prevalence of social anxiety disorder, generalized anxiety disorder, major depression and total mood and anxiety disorders, as well as higher symptom scores on the POMS, was found in hyperthyroid women with Graves' disease in comparison with the control group. A prevalence of total anxiety disorder, as well as history of mania or hypomania and lifetime bipolar disorder, but not lifetime unipolar depression, was more frequent in both the euthyroid and the hyperthyroid subgroups of study women in comparison with the control group.

CONCLUSIONS

These results confirm a high prevalence of mood and anxiety disorders in women with treated hyperthyroidism and ophthalmopathy caused by Graves' disease. Hyperthyroidism plays a major role in psychiatric morbidity in Graves' disease.
