Egg consumption and the risk of type 2 diabetes mellitus: a case-control study

OBJECTIVE Type 2 diabetes mellitus appears to involve an interaction between susceptible genetic backgrounds and environmental factors including highly calorific diets. As it is important to identify modifiable risk factors that may help reduce the risk of type 2 diabetes mellitus, the aim of the present study was to determine the association between egg consumption and the risk of type 2 diabetes mellitus. DESIGN A specifically designed questionnaire was used to collect information on possible risk factors of type 2 diabetes mellitus. The odds ratios and 95 % confidence intervals for type 2 diabetes mellitus were calculated by conditional logistic regression. SETTING A case-control study in a Lithuanian out-patient clinic was performed in 2001. SUBJECTS A total of 234 cases with a newly confirmed diagnosis of type 2 diabetes mellitus and 468 controls free of the disease. RESULTS Variables such as BMI, family history of diabetes, cigarette smoking, education, morning exercise and plasma TAG level were retained in multivariate logistic regression models as confounders because their inclusion changed the value of the odds ratio by more than 10 % in any exposure category. After adjustment for possible confounders more than twofold increased risk of type 2 diabetes mellitus was determined for individuals consuming 3-4·9 eggs/week (OR = 2·60; 95 % CI 1·34, 5·08) and threefold increased risk of the disease was determined for individuals consuming ≥5 eggs/week (OR = 3·02; 95 % CI 1·14, 7·98) compared with those eating <1 egg/week. CONCLUSIONS Our data support a possible relationship of egg consumption and increased risk of type 2 diabetes mellitus.

The incidence of type 1 diabetes mellitus among 15-34 years aged Lithuanian population: 18-year incidence study based on prospective databases

BackgroundThe aim of this prospective study was to determine the incidence of type 1 diabetes mellitus in 15-34-year-aged Lithuanian males and females during 1991 - 2008MethodsA contact system with general practitioners covering 100% of the 15-34-year-aged Lithuanian population was the primary data source. Reports from regional endocrinologists and statistical note-marks of State patient insurance fund served as secondary sources for case ascertainment.ResultsThe average age-standardized incidence rate was 8.30 per 100,000 persons per year (95% Poisson distribution confidence interval [CI] 7.90-8.71) during 1991 - 2008 and was statistically significantly higher among males (10.44 per 100,000 persons per year, 95% CI 9.82-11.10) in comparison with females (6.10 per 100,000, 95% CI 5.62-6.62). Male/female rate ratio was 1.71 (95% CI 1.63-1.80). Results of the linear 1991 - 2008 regression model showed that the incidence of Type 1 diabetes in 15-34-year-aged males and females decreased slightly over the time (r = -0.215, p > 0.05).ConclusionsOur data demonstrated the male predominance in primary incidence of type 1 diabetes mellitus in 15-34-year-aged population in Lithuania. The incidence of type 1 diabetes mellitus in 15-34-year-aged males and females decreased slightly during 1991-2008.

The risk of early cardiovascular disease in Lithuanian diabetic children and adolescents: A type 1 diabetes register database based study

AIMS The aim was to assess the frequency and correlates of selected cardiovascular disease risk factors among Lithuanian children and adolescents with type 1 diabetes mellitus (T1DM). METHODS A cohort of 539 T1DM children was investigated. Total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglyceride (TG), glycated haemoglobin (HbA1c) was determined. RESULTS The mean of HbA1c was 8.5 ± 1.8%. Overweight was present in 72 (13.4%, 95% CI 10.6-16.9) and 113 (21.0%, 95% CI 17.5-25.3) had arterial hypertension. Hypercholesterolemia was diagnosed in 120 (22.3%; 95% CI 18.6-26.7), decreased HDL in 22 (4.1%; 95% CI 2.7-6.2), high LDL in 79 (14.7%; 95% CI 11.8-18.3), and high TG in 96 (17.8%, 95% CI 14.7-21.9) subjects. There were positive linear correlations between TG and high HbA1c levels (r=0.192; p<0.001), and between LDL and high HbA1c levels (r=0.238; p<0.001). Two cardiovascular risk factors were present 14.3%, three risk factors in 6.9%, four in 2.4% and five in 0.9%. The frequency of two cardiovascular risk factors was higher among 10-17-year-old T1DM patients than among 1-9-year-old children (27.0% vs. 13.3% respectively, p<0.01). CONCLUSION The frequency of cardiovascular risk factors is common in young people with T1DM and was associated with poor glycaemic control.

Diabetes distress in adult type 1 diabetes mellitus men and women with disease onset in childhood and in adulthood

THE AIM To determine whether or not diabetes distress varies by age of type 1 diabetes mellitus (T1DM) onset and/or gender. SUBJECTS AND METHODS A total of 700 adult T1DM patients were randomly selected from the Lithuanian Diabetes Registry; 214 of them (30.6%) agreed to participate and were recruited for the study. Diabetes distress (emotional burden, physician-related distress, regimen-related distress, interpersonal distress) was compared in 105 (42 men and 63 women) patients with T1DM diagnosed during 0-18years of life, and in 109 (61 men and 48 women) with T1DM diagnosed in adulthood, using Diabetes Distress Scale (DDS). RESULTS Adult childhood-onset T1DM women have higher regimen-related distress (36.3±21.3 vs 26.6±16.2, p=0.016) than adulthood-onset women. Adult childhood-onset T1DM women experience higher diabetes distress (higher emotional burden (27.0±22.0 vs 15.6±16.4, p=0.006), physician-related distress (34.4±33.9 vs 20.7±29.4, p=0.024), total diabetes distress (41.2±13.6 vs 34.8±10.9, p=0.011)) than childhood-onset men. Adulthood-onset T1DM women experience higher physician-related distress (39.2±37.6 vs 23.4±32.5, p=0.013), but lower regimen-related distress (26.6±16.2 vs 35.8±21.6, p=0.014) than adulthood-onset men. In conclusion our findings reinforce the interdependence of psychological and biomedical factors in influencing health outcomes and support the need to provide psychological assessment and support to patients with T1DM.

Adding Salt to Meals as a Risk Factor of Type 2 Diabetes Mellitus: A Case-Control Study.

Objective: Type 2 diabetes mellitus (T2DM) is thought to arise from the complex interplay between genetic and environmental factors. It is important to identify modifiable risk factors that may help to reduce the risk of diabetes. Data on salt intake and the risk of type 2 diabetes are limited. The aim of this study was to assess the relationship between adding salt to prepared meals and the risk of type 2 diabetes. Methods: In a case–control study, we included 234 cases, all of whom were patients aged 35–86 years with a newly confirmed diagnosis of T2DM, and 468 controls that were free of the disease. Cases and controls (ratio 1:2) were matched by gender and age (±5 years). A questionnaire was used to collect information on possible risk factors for diabetes. Adding salt to prepared meals was assessed according to: Never, when there was not enough, or almost every time without tasting. The odds ratios (OR), and 95% confidence intervals (CI) for type 2 diabetes was calculated using a conditional logistic regression. Results: The cases had a higher body mass index and a significantly lower education level compared to the controls. Variables such as waist circumference, body mass index, eating speed, smoking, family history of diabetes, arterial hypertension, plasma triglycerides, educational level, occupational status, morning exercise, marital status, daily urine sodium excretion, and daily energy intake were retained in the models as confounders. After adjusting for possible confounders, an approximately two-fold increased risk of type 2 diabetes was determined in subjects who add salt to prepared meals when “it is not enough” or “almost every time without tasting” (1.82; 95% CI 1.19–2.78; p = 0.006) compared with never adding salt. Conclusion: Presented data suggest the possible relationship between additional adding of salt to prepared meals and an increased risk of type 2 diabetes.

Aortopathies in Turner syndrome — new strategies for evaluation and treatment

Turner syndrome is a rare genetic disorder which impairs womens growth, reproductive function, cardiovascular development and other functions. This syndrome has been proposed as an independent risk marker for cardiovascular disease. Despite this, life-threatening cardiovascular outcomes affecting young women are dismissed because of incomplete follow up. During assessment due to their smaller stature, it should be noted that, although the ascending aorta diameter is normal in absolute terms, after indexation for body size, patients with Turner syndrome may have a dilated aorta.Based on recent guidelines and the latest studies, there is new evidence on the use of magnetic resonance imaging in diagnosing aortic lesions. New management possibilities of aortopathies have also been discussed. This approach should optimise medical care for women with Turner syndrome, but many areas of uncertainty still remain in the diagnosis and management of this syndrome, and new prospective studies are needed.

Profile of mood states in adult type 1 diabetes mellitus men and women with disease onset in childhood and in adulthood.

Abstract Introduction: Although diabetes may not be associated with psychopathology, it may be associated with less severe disturbances in psychosocial functioning. Emotional problems in relation to type 1 diabetes are usually analysed as symptoms of psychiatric conditions but not as states of mood. The aim was to compare profiles of mood states in adult patients with childhood-onset and adulthood-onset type 1 diabetes mellitus and to outline possible gender-specific differences. Subjects and methods: A total of 214 adult type 1 diabetic patients were randomly selected from the Lithuanian Diabetes Registry. The mood states were compared in 105 (42 men and 63 women) patients with type 1 diabetes diagnosed during 0–18 years of life and in 109 (61 men and 48 women) diagnosed in adulthood. The scores of tension-anxiety, depression-dejection, anger-hostility, vigour-activity, fatigue-inertia and confusion-bewilderment were evaluated using the Profile of Mood States. Results: Depression-dejection was higher in adulthood-onset diabetic women than in childhood-onset (p=0.005) diabetic patients. In childhood-onset diabetic patients depression-dejection (p=0.046) and confusion-bewilderment (p=0.033) were higher in women than in men. Adulthood-onset women with diabetes had higher tension-anxiety (p=0.027), depression-dejection (p=0.001), and confusion-bewilderment (p=0.004) scores than men. Multiple logistic analyses showed that adulthood-onset period of type 1 diabetes is associated with higher levels of depression-dejection [OR=1.1; 95% confidence intervals (CI) 1.01–1.19, p=0.025], longer diabetes duration (OR=2.00; 95% CI 1.27–2.03, p=0.012), higher HbA1c level (OR=1.15; 95% CI 1.02–1.3, p=0.023), and female gender (OR=2.51; 95% CI 1.29–2.90, p=0.021). Conclusions: Profile of mood states in adult women with type 1 diabetes is worse than in men. Adulthood-onset type 1 diabetic women have higher depression-dejection than do childhood-onset diabetic patients. Adulthood-onset period of type 1 diabetes is associated with higher levels of depression-dejection, longer diabetes duration and female gender.

Effect of ginkgo extract on eye microcirculation in patients with diabetes

The prevalence of Diabetes mellitus has increased around the world in the last decade. Anyone with diabetes is at risk of diabetic eye complications. The aim of the study was to compare effects of standardized Ginkgo biloba (Ginkgo biloba L.) dry extract (Ex.Gb) with the placebo on the microcirculation lesions of the eye in randomized double-blind placebo-controlled trial. 44 patients with type 2 diabetes mellitus were randomized to Ex.Gb 160 mg per day or placebo, and were followed up for nine months. Dose of Ex.Gb was increased to 240 mg in next nine months. Total Antioxidant Status (TAS) of plasma was measured using the Trolox equivalent antioxidant capacity assay. Ophthalmologic examination was performed by the biomicroscopic method. Vascular, intravascular and perivascular alterations were evaluated, and total conjunctival index was calculated. Though the values of the total conjunctival index and its constituent decreased (P<0.05) during the study in Ex.Gb group, there were no significant differences between these parameters as compared with placebo group. Evaluation of plasma TAS showed gradually increment, although insignificant and very small, in Ex.Gb group. The significance of Ex.Gb on development of the alterations of eye microcirculation, especially in elder patients needs to be explored further.

The prevalence of type 1 diabetes mellitus among 15–34-year-aged Lithuanian inhabitants during 1991–2010

AIMS To summarize the data on the prevalence of type 1 diabetes mellitus among 15-34-year-aged Lithuania inhabitants (1991-2010). METHODS New prevalent cases consist of growing-up patients with diabetes onset in childhood, i.e., up to 14 years, new onset 15-34-year-aged type 1 diabetic patients Lithuanian inhabitants, and immigrants. The data on type 1 diabetes was collected with the help of general practitioners and regional endocrinologists in Lithuania. RESULTS On 31 December 1991, there were 1202 adolescent and adult 15-34-year-aged patients with type 1 diabetes mellitus or 103.59 per 100,000 inhabitants of the same age group (95% Poisson CI 97.90-109.62), and at the end of 2010 - 1533 or 187.80 (178.63-197.44), respectively in Lithuania. During 19-year period the mean increase of type 1 diabetic patients was 1.25±1.94% per year or 1.47±2.74 per 100,000 inhabitants per mean year of the study period (for males 1.42±2.14% or 1.69±3.05/100,000 and for females 1.05±1.99%, or 1.24±2.92/100,000). Regression-based linear trends showed that the prevalence of type 1 diabetes mellitus in 15-34-year-age group had a tendency to increase among males (r=0.953; p<0.001) and females (r=0.970; p<0.001). The age adjusted prevalence frequencies for males and females in 1991 were correspondingly 102.81/100,000 and 104.55/100,000, and in 2010 - 193.75 and 182.01. CONCLUSION The prevalence of type 1 diabetes mellitus among 15-34-year-age males and females had a tendency to increase during 1991-2010.

Smoking habits and Type 2 diabetes mellitus in women

ABSTRACT The purpose of this case–control study was to evaluate the relationship between smoking and type 2 diabetes mellitus (T2DM) in adult females. A total of 168 women in Kaunas, Lithuania with newly diagnosed T2DM during the year 2001 and 336 controls who were women without diabetes were recruited. Participants were asked about their duration of smoking, the number of cigarettes smoked per day, pack-years, and smoking cessation. Odds ratios (OR), 95 percent confidence intervals (CI) for T2DM were calculated using conditional logistic regression. After adjustment for possible confounders, women with T2DM had a nearly threefold higher odds for smoking 10 or more cigarettes per day compared with controls and using never smokers as the referent category (OR = 2.8; 95 percent CI 1.0–7.7). Women with T2DM had over fourfold odds for having smoked for 40 years or more compared to controls (OR = 4.6; 95 percent CI 1.1–18.6). Compared to controls, women with T2DM had over a sixfold higher odds for stopping smoking for 19 or fewer years with never smokers as the referent category (OR = 6.4; 95 percent CI 1.5–27.3). The findings of our study suggest a possible relationship between smoking and T2DM in women. Also, despite smoking cessation, the association with T2DM remained for a long time.
