RESUMEN
Proper blood collection and timely analysis are vital steps for reliable results. This study aims to compare potassium(K), calcium(Ca), and phosphorus(P) concentrations in serum separator tube (SST), lithium heparin tube without gel (LiH), and lithium heparin tube with a barrier (Barricor)tubes in essential thrombocytosis(ET) patients. Additionally, we assessed short-term stability of these analytes at room temperature. K, Ca and P concentrations of blood taken from 40 ET patients into SST, LiH and Barricor tubes were measured at 0, 2, 4 and 8 h. We calculated the percentage difference and defined the maximum permissible difference (MPD) using the Biological Variation Database. Intertube comparisons were conducted using Passing-Bablok regression and Bland-Altman analysis. Comparing SST to LiH, the percentage difference values for all tests exceeded the MPD. When comparing Barricor to LiH, K and Ca tests were above MPD, except for P. At the 8th hour, LiH showed clinically significant changes in all three electrolytes. Barricor exhibited stability for K, Ca, and P for up to 8 h, with only Ca levels borderline higher than the MPD. Our study reveals clinically significant alterations in K, Ca, and P concentrations in SST compared to LiH tubes, and in K and Ca concentrations in Barricor compared to LiH tubes. While K, Ca and P concentrations were stable for up to 4 h at room temperature in all tube types tested, significant changes were observed in all electrolytes at 8 h in the LiH tube.

PURPOSE: Obesity, a low-grade systemic inflammatory disease, causes inflammation in metabolic tissues. Galectin-3(Gal-3) is one of the lectin molecules involved in inflammatory processes. We evaluated the possible relationship between Gal-3 level and the metabolic inflammatory process before and after obesity surgery. METHODS: One hundred participants were included in the study and classified as normal weight, overweight, Class I, II, and III obese. Class III obese group underwent bariatric surgery and evaluated in the 3rd and 6th months after surgery. Glucose, insulin, glycated hemoglobin A1c (HbA1c), homeostatic model assessment of insulin resistance (HOMA-IR), high sensitivity C-reactive protein (hsCRP), Gal-3, interleukin (IL)-6, IL-10, adiponectin, and leptin levels were determined. RESULTS: Gal-3 levels were higher in Class III obese compared to the normal weight group. Postoperative leptin and hsCRP levels were decreased significantly, but the decrease in IL-6 and Gal-3 levels were not significant. Postoperative increased adiponectin and IL-10 levels were significant. Gal-3 was found significantly higher in insulin resistant group. The correlation between Gal-3 with BMI, adiponectin, leptin, hsCRP levels, and HOMA-IR was found weak. CONCLUSION: These findings might support the fact that Gal-3 is one of the molecules involved in the linkage between insulin resistance and meta-inflammation in morbid obese.

OBJECTIVES: In this study, our aim was to determine the differences between intrauterine growth restriction (IUGR) and normal birth weight fetuses in terms of ischemia modified albumin (IMA) levels. For this purpose, we measured ischemia modified albumin levels in the cord blood of fetuses and venous blood of mothers. MATERIAL AND METHODS: This study is a prospective study conducted at University of Health Sciences Tepecik Training and Research Hospital between January 2018 and December 2019. According to the inclusion/exclusion criteria, 227 patients were included in the study. Participants were divided into two groups according to the presence (patient group) or absence (control group) of intrauterine growth restriction (IUGR). In addition to routine parameters recorded during pregnancy, the IMA levels and Doppler USG findings of all participants were recorded. RESULTS: The mean cord blood serum IMA levels of the patient group were significantly elevated compared to controls (p = 0.038). Whereas mean maternal blood serum IMA levels were similar among groups (p = 0.453). The cord blood and mother blood serum IMA levels were not significantly different with regard to the presence or absence of perinatal asphyxia. CONCLUSIONS: In the literature, studies evaluating IMA levels in the cord and maternal blood of IUGR fetuses are limited. In IUGR patients, IMA level is expected to increase and in our study, IMA levels were significantly increased but the presence of oxidative stress has not been found to affect IMA levels.
