Anxiety disorders as predictors of suicidality in people with type 2 diabetes mellitus: Findings of a study in six European countries. / Zaburzenia lekowe jako predyktory samobójczosci u osób z cukrzyca typu 2: Wyniki badania przeprowadzonego w szesciu europejskich krajach.

OBJECTIVES: Anxiety disorders are significant predictors of suicidality and are proposed to be independent risk factors for suicide attempts. They are common in people with type 2 diabetes (T2DM) and are associated with longer duration of diabetes and poorer treatment outcomes. The aim was to examine associations between anxiety disorders and suicidal thoughts and behaviour in people with T2DM, to establish the prevalence of suicidality among people with T2DM in the selected European countries and to examine whether anxiety disorders were predictive of current outcomes of suicidality in this population using data from the International Prevalence and Treatment of Diabetes and Depression study. METHODS: The study sample comprised 1063 adults with T2DM from 6 European countries. The presence of anxiety disorders and suicidality was assessed with the MINI International Neuropsychiatric Interview. The group of participants with current suicidal risk was compared with the group of participants with no suicidal risk. RESULTS: The participants from Germany were more likely to report suicidality than those from other countries, whereas people from Serbia and Ukraine were less likely to report it. Depression and anxiety disorders significantly contributed to the increased presence of suicidality among people with T2DM. Agoraphobia was a significant predictor of suicidality when controlling for depression. The participants with T2DM and comorbid agoraphobia had 4.86 times higher odds to report suicidality than those without agoraphobia. CONCLUSIONS: Agoraphobia was a significant predictor of suicidality in people with T2DM.

Diabetic Ketoacidosis in Patients with Maturity-Onset Diabetes of the Young.

Maturity-onset diabetes of the young (MODY) is the most frequent monogenetic diabetes form. It is caused by mutations in genes important for the development and function of pancreatic beta-cells, resulting in impaired insulin secretion capacity. Up to now, 14 different types have been described. The inheritance pattern is autosomal dominant, leading to a strong family history with more than three affected generations. Young age at diagnosis and lack of pancreatic autoantibodies are further characteristics of MODY. The presence of diabetic ketoacidosis (DKA) was long regarded as an exclusion criterion for MODY. However, in recent years, several case reports on MODY patients presenting with DKA have been published. The present study aimed to give an overview of the current knowledge of DKA in MODY patients, with a collection of published case studies as a prerequisite for this review.

Homeostasis Model Assessment of ß-Cell Function for Diagnosis of Insulinoma.

CONTEXT: Diagnosis of insulinoma is based on different criteria from the 72-hour fasting test according to current guidelines (Endocrine Society [ES], European [ENETS], and North American [NANETS] Neuroendocrine Tumor Societies), including assessment of ß-cell function by glucagon stimulation test. OBJECTIVE: This study tested whether the homeostasis model assessment of insulin secretion, including assessment of ß-cell function, (HOMA-B) at the end of the fasting test provides comparable efficacy for insulinoma diagnosis. METHODS: In 104 patients with suspected insulinoma, 72-hour fasting tests were performed with frequent assessment of glucose, insulin, and C-peptide in venous blood. HOMA-B values using insulin and C-peptide were calculated at the end of the fasting test, as defined by the lowest glucose concentration from each participant. RESULTS: HOMA-B was more than 6.5-fold higher in patients with (n = 23) than in those without (n = 81) insulinoma (insulin and C-peptide; both P < .001). HOMA-B (cutoff using insulin >253 a.u. and C-peptide >270 a.u.) had a sensitivity of 0.96, 0.78 to 1.00, and a specificity of 0.96 or greater (≥0.89-0.99) for insulinoma diagnosis. ES and ENETS/NANETS criteria reached a diagnostic sensitivity of less than or equal to 0.96 (≤0.78-1.00) and ≤0.83 (≤0.61-0.95) as well as specificity of ≤0.85 (≤0.76-0.92) and less than or equal to 1.00 (≤0.96-1.00) for insulin, and C-peptide, respectively. Using insulin for HOMA-B, sensitivity tended to be higher compared to ENETS/NANETS criteria (P = .063) and specificity was higher compared to ES criteria using insulin and C-peptide (both P < .005). CONCLUSION: HOMA-B, as calculated at the end of the fasting test employing defined cutoffs for insulin and C-peptide, provides excellent diagnostic efficacy, suggesting that it might represent an alternative and precise tool to diagnose insulinoma.

Association of a lifestyle score with cardiometabolic markers among individuals with diabetes: a cross-sectional study.

INTRODUCTION: To investigate the associations of a lifestyle score with various cardiovascular risk markers, indicators for fatty liver disease as well as MRI-determined total, subcutaneous and visceral adipose tissue mass in adults with new-onset diabetes. RESEARCH DESIGN AND METHODS: This cross-sectional analysis included 196 individuals with type 1 (median age: 35 years; median body mass index (BMI): 24 kg/m²) and 272 with type 2 diabetes (median age: 53 years; median BMI: 31 kg/m²) from the German Diabetes Study. A healthy lifestyle score was generated based on healthy diet, moderate alcohol consumption, recreational activity, non-smoking and non-obese BMI. These factors were summed to form a score ranging from 0 to 5. Multivariable linear and non-linear regression models were used. RESULTS: In total, 8.1% of the individuals adhered to none or one, 17.7% to two, 29.7% to three, 26.7% to four, and 17.7% to all five favorable lifestyle factors. High compared with low adherence to the lifestyle score was associated with more favorable outcome measures, including triglycerides (ß (95% CI) -49.1 mg/dL (-76.7; -21.4)), low-density lipoprotein (-16.7 mg/dL (-31.3; -2.0)), and high-density lipoprotein cholesterol (13.5 mg/dL (7.6; 19.4)), glycated hemoglobin (-0.5% (-0.8%; -0.1%)), high-sensitivity C reactive protein (-0.4 mg/dL (-0.6; -0.2)), as well as lower hepatic fat content (-8.3% (-11.9%; -4.7%)), and visceral adipose tissue mass (-1.8 dm³ (-2.9; -0.7)). The dose-response analyses showed that adherence to every additional healthy lifestyle factor was associated with more beneficial risk profiles. CONCLUSIONS: Adherence to each additional healthy lifestyle factor was beneficially associated with cardiovascular risk markers, indicators of fatty liver disease and adipose tissue mass. Strongest associations were observed for adherence to all healthy lifestyle factors in combination. TRIAL REGISTRATION NUMBER: NCT01055093.
