Objective: The main aim of the study was to evaluate the patients' glycemic control and adherence to self-care tasks. Materials and methods: Patients with type 1 diabetes mellitus (T1DM) or latent autoimmune diabetes of the adult (LADA) using a multiple daily injection (MDI) regimen with carbohydrate counting (n = 25, Subgroup B) or fixed insulin dose (n = 25, Subgroup C) were allocated to use the application (app) for 12 weeks. Both subgroups were compared with each other and against a control group (n = 25, Group A) comprising patients with T1DM or LADA treated with continuous subcutaneous insulin infusion (CSII) in a parallel-group, open-label, clinical treatment trial. All patients had glycated hemoglobin (A1C) levels measured and were asked to fill out the Diabetes Self-Management Profile (DSMP) questionnaire at study start and end. The patients were instructed to measure capillary glucose six times daily in study weeks 4, 8, and 12. Results: Mean A1C levels decreased 0.725% in Subgroup C in intragroup analysis (p = 0.0063), and had a mean variation of 0.834% compared with Group A (p = 0.003). Mean DSMP scores increased 5.77 points in Subgroup B in intragroup analysis (p = 0.0004) and increased by a mean of 6.815 points in relation to Group A (p = 0.002). Conclusion: OneTouch Reveal improved both A1C levels and DSMP scores in patients with T1DM or LADA compared with standard treatment (CSII).

In the adult organism, angiogenesis is restricted to a few physiological conditions. On the other hand, uncontrolled angiogenesis have often been associated to angiogenesis-dependent pathologies. A variety of animal models have been described to provide more quantitative analysis of in vivo angiogenesis and to characterize pro-and antiangiogenic molecules. However, it is still necessary to establish a quantitative, reproducible and specific method for studies of angiogenesis factors and inhibitors. This work aimed to standardize a method for the study of angiogenesis and to investigate the effects of thalidomide on angiogenesis. Sponges of 0.5 x 0.5 x 0.5 cm were implanted in the back of mice groups, control and experimental (thalidomide 200 mg/K/day by gavage). After seven days, the sponges were removed. The dosage of hemoglobin in sponge and in circulation was performed and the ratio between the values was tested using nonparametric Mann-Whitney test. Results have shown that sponge-induced angiogenesis quantitated by ratio between hemoglobin content in serum and in sponge is a helpful model for in vivo studies on angiogenesis. Moreover, it was observed that sponge-induced angiogenesis can be suppressed by thalidomide, corroborating to the validity of the standardized method.

Decreasing glycemic variability (GV) is become a criterion of glycemic control and important goal in the treatment of diabetes. Despite this importance there are only a few reports on GV using continuous glucose monitoring (CGM) patients with T2D on basal insulin. The aim of this exploratory study was to compare the GV after 12 weeks of treatment on Glargine-100U (Glar-100) or Glargine-300U (Glar-300) in T2D patients. Methods: This is 12-week, randomized with parallel arms. Ninety-four T2D subjects >18 y old with HbA1c between 7.5% -11% (9.2±0.9%) on NPH insulin ÷ OAD, were randomized to Glar-100 or Glar-300. A blinded CGM was inserted in a baseline (run-in) and after 12-week patient- driven titration period. The CGM parameter included TIR (70-180mg/dl), MAGE, CV, time in hypoglycemia and in hyperglycemia ranges were uploaded by carelink software and the GV parameters were analyzed by Glyculator software. Results: No differences between groups was found in any analysed GV parameter. The final HbA1c were similar to Glar-100 and Glar-300(8.0±1.12 and 8.15±1.04), however there were a significant difference regarding on total hypoglycemic events verified by self-monitoring blood glucose (SMBG) Glar-100 and Glar-300 groups (0.44±0.43 vs. 0.25± 0.42 episodes/patient/year respectively, p= 0.007). In exploratory analysis in the quartile that reached the HbA1c <7.4% TIR for Glar-300 group was 75.43% and 65.62% for Glar-100 (NS). Conclusion: In this exploratory study, even when we could not detect differences between GV parameters (probably due to not reaching target glycemic control), the lower risk of hypoglycemia with Glar-300 compared to Glar-100 can still be clearly shown. A tendency for longer TIR stay in the Glar-300 group vs. in the Glar-100 group was seen in the subgroup of those who reached close-to-target A1c values. Disclosure D.R.

Introduction: neuroendocrine tumors (NET) are a very rare and heterogeneous group of malignancies that can be associated with adrenocortical tumors in approximately 20% of the cases, mostly bilateral and non-functioning. Autonomous cortisol secretion occurs in less than 10% of adrenal incidentalomas and the coexistence of pancreatic neuroendocrine neoplasms and autonomous cortisol secretion is not well-described. Clinical case: a 54-year-old man with previous history of systemic hypertension and type 2 diabetes mellitus, presented with left hypochondrium pain in the last 18 months, associated with abdominal distension, constipation and nausea. Physical examination without abnormalities. Abdominal tomography demonstrated dilatated pancreatic duct and a solid heterogeneous nodule in left adrenal, measuring about 2.7 cm. Ecoendoscopy revealed a heterogeneous, hypoechoic and oval nodular lesion, located at the transition of pancreatic head and uncinate process, measuring 1.5x1.1cm. Biopsy was performed, showing a pattern of neuroendocrine neoplasia, with chromogranin and synaptophysin +, Ki67 1%. Gallium-68 dotatate PET revealed two pancreatic nodular formations, one in proximal neck/body (1.5 cm) and the other in pancreatic tail (1 cm), presenting SUV of 20.4 and 21, respectively. Adrenal nodule presented minimal increase in radiopharmaceutical concentration. To exclude the hypothesis of metastasis, PET FDG was performed, showing physiological uptake in adrenal nodule. Pituitary MRI had no abnormalities. Chromogranin A and gastrin values were normal. Pheochromocytoma and primary hyperaldosteronism were excluded. Hypercortisolism investigation presented the following results: 23h salivary cortisol 167ng/dl (NR < 100), 24-hour free urinary cortisol 42.1 mcg/24h (NR 4.2-60), post-1mg and 2mg dexamethasone serum cortisol of 10.8 mcg/dl and 3.8 respectively (serum dexamethasone levels of 193 and 780 ng/dl; NR > 130), ACTH 13 and 11 pg/ml. By these results, coexistence of non-functioning pancreatic neuroendocrine tumor and autonomous cortisol secretion was confirmed. A total pancreatectomy with partial gastrectomy and bileodigestive anastomosis was performed. Pathological anatomical evidence demonstrated a well-differentiated neuroendocrine tumor (NET G1) and immunohistochemistry analyses showed positive chromogranine A, synaptophysine, Ki67 1% and negative ACTH. Clinical follow-up of the adrenal adenoma was preferred. Conclusion: although most adrenocortical tumors associated with NET are nonfunctional, hypercortisolism should be considered. Adrenal metastasis and ectopic ACTH secretion are differential diagnosis. Clinical follow-up is an option when patient is asymptomatic and comorbidities are well-controlled.
