RESUMEN

AIM: To investigate the association between vitamin D3 level and oxidative stress biomarkers such as Heat Shock Protein 70 (HSP70), ferric reducing ability of plasma (FRAP), advanced oxidation protein products (AOPP) and advanced glycation end products (AGEs) in patients with Type 2 diabetes. METHOD: In this cross-sectional study, 54 patients including 32 females and 22 males with a mean age of 54.92 ± 11.37 years with T2D attending the diabetes clinic from 2021 to 2022 were included. According to the average level of vitamin D in this population (14.91), they were divided into two groups with vitamin D ≤15 ng/mL and vitamin D >15 ng/mL. Multivariate regression analysis was conducted to evaluate the relationship between vitamin D and AOPP, HSP and FRAP parameters. The correlation between vitamin D and other variables was evaluated via the Pearson correlation test. RESULT: Vitamin D level had a positive relation with FRAP (ß = 0.32, p = 0.017) and HSP (ß = 0.39, p = 0.003), but had a negative relation with AOPP (ß = -0.30, p = 0.02). The level of 2hPP also had a negative relation with the level of vitamin D (ß = -0.33, p = 0.03). There was not any relationship between the level of vitamin D and AGEs or other variables. After adjusting for multiple confounders for the multivariate regression model, HSP remained significant. CONCLUSION: This research indicates the relationship between vitamin D levels and oxidative stress biomarkers in patients with Type 2 diabetes.

RESUMEN

Key clinical message: Struma ovarii (SO), is a rare and specialized ovarian teratoma. The treatment is controversial depending on the risk of recurrence and metastasis. Here a SO with papillary thyroid carcinoma is reported and the approach is thoroughly discussed. Abstract: Struma ovarii (SO) is a highly specialized ovarian teratoma primarily composed of thyroid tissue. Clinical features associated with SO include lower abdominal discomfort, unusual vaginal bleeding, ascites, and hyperthyroidism. While SO rarely transforms into malignancy, the optimal degree of treatment remains controversial due to the varying risks of recurrence and metastasis. In this report, we present the case of a 64-year-old woman experiencing abdominal pain and diagnosed with SO, accompanied by papillary thyroid carcinoma. We thoroughly discuss the evaluation and management of this rare condition.

RESUMEN

BACKGROUND: Lipoprotein a (LP(a)), an LDL-like lipoprotein, known as a risk factor for cardiovascular diseases, has a controversial association with diabetic retinopathy in patients with type 2 diabetes-the current systematic review aimed to critically assess the association between LP(a) and diabetic retinopathy. METHODS: A systematic review of relevant studies was conducted after a thorough search in PubMed, Scopus, and Google Scholar electronic databases. We used English observational, case-control, and prospective cohort studies published up to August 2022, including type 2 diabetic patients as the population, diabetic retinopathy as the outcome, and LP(a) as the intervention. RESULT: 17 relevant studies, including 4688 patients with diabetes, were included in this systematic review. While in 13 studies, Lipoprotein(a) was recognized as a risk factor for diabetic retinopathy, only three studies reported no evidence of a relationship between the two. Also, another study showed a mixed outcome of the relationship between LP(a) and diabetic retinopathy. CONCLUSION: High serum lipoprotein(a) in patients with type 2 diabetes is considered a risk factor for diabetic retinopathy. However, further large-scaled cohort studies are still required to validate this finding.

RESUMEN

BACKGROUND: Metabolic-associated fatty liver disease (MAFLD), one of the most common liver diseases, is detected in patients with concomitant hepatic steatosis and Type 2 Diabetes (T2D). We looked into the relationship between Fibrosis-4 (FIB-4) index and coronary artery diseases (CAD) in patients with MAFLD, to further look into the efficiency of FIB-4 in screening for CAD among patients with MAFLD. METHOD: In this study, we included 1664 patients with MAFLD (T2D, who also had hepatic steatosis) during 2012-2022 and divided them into 2 groups; CAD and non-CAD. Demographic, Anthropometric indices, liver function tests, lipid profile and FIB-4 index of all patients were evaluated and compared. RESULT: Among the 1644 patients (all have MAFLD), 364(21.4%) had CAD. Patients with MAFLD and CAD were more probable to be hypertensive, have longer duration of diabetes and be older (with p-values < 0.001). After adjustment for confounding factors, in a multivariable logistic regression model, FIB4 showed a significant independent relationship with concomitant MAFLD and CAD. Upper Tertile FIB-4 had an odds ratio of 3.28 (P-value = 0.002) to predict CAD. Furthermore, in Receiver Operating Characteristic (ROC) Curve analysis with the maximum Youden Index, a FIB-4 cut-off of 0.85 (AUC = 0.656, 95% CI 0.618-0.693, P < 0.001) noted to predict CAD in patients with MAFLD. CONCLUSION: This study showed that the FIB-4 score independently correlates with CAD in patients with MAFLD.
