RESUMEN
AIMS: The impact of prolonged COVID-19 lockdown on metabolic control in type 2 diabetes patients and healthy individuals has not exactly been known. We aimed to evaluate the change in body weight and metabolic control in type 2 diabetic and non-diabetic healthy subjects during the prolonged lockdown period. METHODS: Diabetic (n = 85), and age-and sex-matched non-diabetic subjects (n = 55) were included in this prospective study. Body mass index and metabolic parameters were compared between before and 6th months of lockdown. Changes in values were evaluated using the difference before and after lockdown. RESULTS: Age (54.81 ± 10.53 vs. 52.61 ± 4.88 years), gender (female, 68.2% vs. 56.4%) and, BMI (33.44 ± 6.48 vs. 31.63 ± 3.57 kg/m2) were similar between groups (p > 0.05). Before and after lockdown, BMI increased both in non-diabetic (0.54 ± 0.95 kg) and diabetic groups (1.91 ± 5.48 kg) (p > 0.05). Increase in HbA1c was more in diabetic than in non-diabetic groups (0.71 ± 1.35 vs. 0.02 ± 0.19%, p = 0.002). Glucose, LDL-C, and TG increased in diabetic (39.69 ± 74.69, 7.60 ± 34.33, and 58.21 ± 133.54 mg/dl, p < 0.05) whereas non significantly decreased in non-diabetic group (-0.51 ± 4.40, -3.52 ± 14.53, and -6.47 ± 41.77 mg/dl, respectively. After adjusting BMI, increase in blood glucose (p = 0.021), HbA1c (p = 0.018), and TG (p = 0.041) levels were more in diabetic than non-diabetic group. Duration of diabetes was an independent predictor of the change in HbA1c (OR: 1.2, 95% CI = 1.1-1.8, p = 0.032). CONCLUSIONS: Body weight gain was observed in type 2 diabetic patients and healthy subjects. This is the first study to show that prolonged lockdown COVID-19 pandemic worsened glucose regulation and increased TG level in diabetes mellitus independent of weight gain.

OBJECTIVE: To determine the characteristics of thyroid nodules by using fine needle aspiration (FNA) biopsy and ultrasonography. PATIENTS AND METHODS: FNAs of 1,004 patients with thyroid nodules between 2000 and 2007 were evaluated retrospectively. The surgical records of 101 of the patients were available and reviewed. The Odds ratios for nodule characteristics were calculated individually. RESULTS: The sensitivity of FNA was 66.7% and the specificity was 95.2%. Positive predictive value was 72.7% and negative predictive value was 93.7%. Our diagnostic accuracy was 90.5%. Solitary nodules, irregular margins and microcalcifications were associated with increased risk of malignancy with Odds ratios 3.61 (95% CI: 1.25-10.42; p= 0,017); 5.44 (95% CI: 1.76-16.78; p= 0,003) and 39.29 (95% CI 8.32-185.47; p< 0.001) respectively. Macrocalcification, age, gender and thyroid status were not associated with increased risk of malignancy. CONCLUSION: Our data suggest that FNA is a reliable, reproducible and valid method to evaluate thyroid nodules and ultrasonographic features, especially microcalcification is a very important predictor of malignancy.

AIM: To investigate if obesity which is not accompanied by diabetes and/or hypertension is associated with microalbuminuria in female patients. MATERIALS AND METHODS: A total of 77 obese female patients from the Outpatient Clinic of Endocrinology of Istanbul University Cerrahpasa Medical Faculty and 30 age-matched, lean, healthy women were enrolled in the study. Patients with accompanying diabetes mellitus, hypertension, obesity associated with any endocrine abnormality, hepatic or renal disease, fever, infectious disease, malignancy were excluded. Weight, height, body-mass index (BMI), waist circumference, waist/hip ratio (WHR) and systolic and diastolic blood pressures were recorded. Albumin excretion in 24-hour urine samples (UAE) were measured using SYNCHRON LX System with MA Microalbumin kit in two separate 24-hour urine samples from every patient. Statistical analysis was performed using t-test and Pearson's correlation in SPSS 12.0 for Windows Program. RESULTS: The median albumin excretion in 24-hour urine sample was similar in obese and control groups (12.01 +/- 10.69 mg/day vs 9.35 +/- 4.09 mg/day; p= 0.211). There were no correlations between the albumin excretion in 24 hour urine samples and BMI, waist circumference, WHR, systolic or diastolic blood pressure. CONCLUSION: Diabetes mellitus and hypertension are known to be associated with microalbuminuria. In our study, microalbuminuria was not detected in obese women without diabetes and/or hypertension and UAE was similar in obese and lean women.

OBJECTIVE: Although obesity is related with cardiovascular disease, the exact mechanism of the relationship is not fully understood. We aim to examine the relationship between plasma viscosity and obesity as a cardiovascular disease risk factor in obese and non-obese groups. METHODS: We recruited 75 obese subjects (mean age: 40.2+/-8.4 years, Body Mass Index: 33.61+/-2.57 kg/m(2)) who were admitted to the Clinic of Endocrinology and Metabolism of Cerrahpasa Medical Faculty. As a non-obese group (n=70, mean age: 41.78+/-9.7 years, Body Mass Index: 21.84+/-3.42 kg/m(2)) healthy subjects from medical and laboratory staff were selected. Plasma viscosity and lipid profile were measured and atherogenic index was calculated as atherogenic risk factors. RESULTS: Plasma viscosity, total cholesterol and LDL-cholesterol levels and atherogenic index were significantly increased in obese group compared to non-obese group for each p<0.001. We found no significant difference in plasma fibrinogen, insulin, albumin and HDL-cholesterol levels between obese and non-obese groups. Plasma viscosity was correlated with total cholesterol and atherogenic index only in the obese group (p<0.05 and p<0.05 respectively). In the non-obese group regarding PV, we determined a positive correlation with triglycerides (r: 0.470, p<0.05) and negative correlation with HDL-C (r: -0.518, p<0.05). CONCLUSION: Plasma viscosity, an early atherosclerotic risk factor, might be helpful in the assessment of cardiovascular risk in obese subjects along with classical cardiovascular risk factors such as plasma cholesterol and atherogenic index.
