ABSTRACT
AIM: To characterize the clinical phenotype of type 2 diabetes mellitus (T2DM) with respect to age, gender, and BMI. METHOD: Anonymized data of 120,183 people with T2DM from the German/Austrian multicenter Diabetes Patienten Verlaufsdokumentation database were analyzed based on chronological age or age at diagnosis (0-19, 20-39, 40-59, 60-79, and ≥80 years). Age, gender, and BMI comparisons with clinical phenotype were made using χ(2) and Kruskal-Wallis tests (SAS V9.2). RESULTS: Of all the patients, 51.3% were male, average age was 67.112.7 years, and average disease duration was 9.99.1 years. More girls than boys were diagnosed during adolescence and more men than women during adulthood (2060 years). No gender differences existed when age at diagnosis was 60 years. Patients were obese on average (BMI: 30.5±6.1 kg/m(2)) and had significantly higher BMI values than German population peers. The BMI gap was widest in the younger age categories and closed with increasing age. Adult women were significantly more obese than men. Obese patients more often had elevated HbA1c (≥7.5%), hypertension or dyslipidemia (irrespective of age), microalbuminuria (adults), or retinopathy (elderly) than nonobese patients. More men than women (20-60 years) had hypertension, dyslipidemia, or microalbuminuria while more women than men (≥60 years) had hypertension or dyslipidemia. CONCLUSION: During puberty, more girls than boys were diagnosed with T2DM while during adulthood males predominated. T2DM manifested at comparatively lower BMI in males, and younger patients were more obese at diagnosis. Age, gender, and BMI were also associated with poor metabolic control and cardiovascular disease comorbidities/complications.

OBJECTIVE: The present publication describes an inflammatory pain model based on an air-stream introduced in the nasal cavity. The aim of the present study was to investigate the influence of flow, humidity and temperature of the air-stream on the intensity of the evoked pain sensations. METHODS: Six healthy volunteers participated in the study. Pain was produced by a stream of air introduced to the nasal cavity at different flow rates (5, 6 and 81/min), humidity (20 and 80% relative humidity) and temperature (16, 24, and 32 degrees C). The evoked pain was quantified by means of visual analogue scales. RESULTS: The air-stream induced a dull and burning painful sensation. The intensity of pain was found to be related to the air-stream's humidity and temperature. Specifically, a dry air-stream (20% relative humidity) evoked significantly stronger pain than a humidified air-stream (80% relative humidity). Pain was significantly greater at a temperature of 32 degrees C than at 24 degrees and 16 degrees C, while the temperatures of 16 and 24 degrees C did not differ with respect to pain intensity. In contrast, a tendency towards stronger pain produced by a flow of 81 compared to that with 51 could not be statistically justified within the present study. CONCLUSIONS: The non-invasive pain stimulus was found to be easily applicable and the evoked pain sensation could be modified by variation of humidity and temperature of the air-stream.
