Introduction: To evaluate the efficacy and safety of transition from premixed and intensive insulin to twice-daily insulin degludec/aspart (IDegAsp) co-formulation in patients with type 2 diabetes mellitus.Material and methods: In this 12-week study, patients receiving twice-daily premixed insulin therapy in group 1 (n = 55) were switched to twice-daily IDegAsp. In group 2 (n = 60), patients on intensive insulin therapy were switched to IDegAsp injected twice a day. Inter- and intragroup comparisons were made.Results: A total of 115 patients were included in the study. There was a significant improvement in glycaemic control, median daily total insulin dose, body mass, body mass index, and hypoglycaemic events in group 1 and group 2 with the switch to IDegAsp (p < 0.05). The decrease in median daily total insulin dose requirement in group 2 was higher than that of group 1 (p = 0.001). There was no difference between groups in terms of other parameters (p > 0.05).Conclusions: The current analysis indicates that IDegAsp treatment improves outcomes, with the most notable differences observed in daily total insulin requirement, body mass, and hypoglycaemia.

Relationship between lymphovascular invasion and clinicopathological features of papillary thyroid carcinoma

Aim BRAF mutation inhibits many tumour suppressor genes, increases pro-angiogenic molecules and reduces radioactive iodine uptake of tumour in papillary thyroid cancer (PTC), giving it more aggressive clinical characteristics. In this study, we aimed to evaluate the effect of BRAF V600E mutation on the clinicopathological features in patients with PTC. Methods The laboratory and clinical findings of 256 PTC patients who were referred to our clinic between 2007 and 2017 were assessed. Subjects involved in the study were divided into two groups depending on the presence of BRAF V600E mutation. Results BRAF V600E mutation testing gave positive results for 65 (25.4%) out of 256 patients. No significant correlation between BRAF V600E mutation, age and gender was detected. There was no difference between the groups in terms of tumour variant, tumour localization, tumour focality, and perineural invasion. In terms of histopathologic characteristics, presence of tumour capsular invasion (p=0.027), extrathyroidal extension (ETE) (p=0.002), absence of pathologically detected lymphocytic thyroiditis (p=0.006) and radio iodine I-131 treatment (p=0.001) were significantly higher in BRAF V600E (+) patients. During a followup period, four patients with BRAF V600E (+) and two patients with BRAF V600E (-) status underwent lateral neck dissection due to lymph node metastasis (p=0.01). Conclusion The presence of BRAF V600E mutation was proved to be a poor prognostic factor. However, in order to further assess the prognostic effect of BRAF V600E mutation in this group of patients and particularly its effect on mortality, long term followup results must be evaluated.

Background and Objectives: This study aimed to investigate the relationship between the systemic immune inflammation (SII) index and the development of micro and macro complications and mortality within the first year and the following three years in type 2 diabetic retinopathy patients. Materials and Methods: The retrospective study included 523 type 2 diabetic retinopathy patients seen in the endocrinology outpatient clinic of our hospital between January and December 2019. Their demographic and clinical characteristics were analyzed using descriptive statistics. The normal distribution of quantitative data was assessed by the Shapiro–Wilk test. Mann–Whitney U, McNemar–Chi-square, and Cochran’s Q tests were used to analyze the SII values and complication rates over time. An ROC analysis determined the sensitivity and specificity of SII. A multiple linear regression analysis examined the relationship between variables and SII, while Spearman’s test assessed the correlation between CRP and SII. p < 0.05 was accepted as significant. Results: The mean age of patients was 63.5 ± 9.3 years, with mean SII values of 821.4 ± 1010.8. Higher SII values were significantly associated with acute–chronic renal failure, peripheral arterial disease, and hospitalization rates in both the first year and the following three years (p < 0.05 for all). Significant cut-off values for SII were found for micro- and macrovascular complications and death within the first year (p < 0.05 for all). The ROC curve analysis identified an optimal SII cut-off value of >594.0 for predicting near-term (1-year) complications and mortality, with a sensitivity of 73.8% and specificity of 49.4% (area under the ROC curve: 0.629, p = 0.001). Multiple linear regression indicated that smoking of at least 20 pack-years had a significant positive effect on SII. The Spearman test showed a weak positive correlation between SII and CRP. Conclusions: High SII values predict both early and late acute–chronic renal failure, peripheral arterial disease, and hospitalizations in patients with type 2 diabetic retinopathy. The study also shows that high SII values may predict microvascular and macrovascular complications of type 2 DM and mortality risk in the early period in patients with type 2 diabetic retinopathy. In addition, comorbidities and inflammatory habits, such as long-term smoking, should be considered in the clinical use of SII.
