Vitamin D in Type 2 Diabetes and Its Correlation With Heat Shock Protein 70, Ferric Reducing Ability of Plasma, Advanced Oxidation Protein Products and Advanced Glycation End Products.

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.

Depression, Anxiety, Perceived Stress and Family Support in COVID-19 Patients.

Objective: Coronavirus disease 2019 (COVID-19) was first reported in Iran in February 2020 and then quickly spread to many cities. Different factors contribute to the numerous psychological problems of this pandemic in patients, healthcare workers and the community. This study investigated the prevalence of perceived stress, anxiety and depression in COVID-19 patients hospitalized between March and April 2020 and revealed associations of these factors with social support received from family. Method : In this cross-sectional study, patients with COVID-19 admitted between 21st of March and 22nd of April 2020 were evaluated by three questionnaires: Anxiety and depression were evaluated using the hospital anxiety and depression scale (HADS), stress levels were evaluated using the four-item perceived stress scale (PSS-4) and family support was evaluated using the perceived social support scale-family (PSS-Fa). In addition to obtaining prevalence of the noted psychological disorders and their relationship with demographic details, relationship of stress, anxiety and depression with family support was also investigated using the Pearson's correlation coefficient. Results: Participants comprised 100 COVID-19 patients (38 females and 62 males). Findings suggested high levels of perceived stress in 26% of the participants, anxiety symptoms existed in 29% and borderline conditions existed in 17%. Moreover, depressive and its borderline symptoms were respectively observed in 17% and 23%. Family support was found to negatively and significantly correlated with anxiety (Pearson correlation = -0.249, P < 0.05) and depression. (Pearson correlation = -0.221, P < 0.05). Conclusion: Given the high prevalence of anxiety and depression in hospitalized COVID-19 patients, it is recommended to further focus on non-clinical interventions, such as providing psychological first aids, boosting psychological resilience, and enabling greater family support, in efforts to prevent transformation of these psychological symptoms into long-term psychological disorders.

Facial hyperpigmentation: Any link to cancer?

INTRODUCTION: Ectopic adrenocorticotropic hormone (ACTH) syndrome is recognized by edema, proximal muscle weakness, hypertension, diabetes and skin hyperpigmentation. This syndrome is mainly associated with malignancies. CASE PRESENTATION: A 43-year-old woman came to our hospital with a history of new-onset diabetes, hypertension, edema and facial hyperpigmentation from four months before. Upon admission, she had alkalosis, hypokalemia, mild hypertension and low-grade fever. Due to abdominal pain, an abdominal ultrasound was performed, which revealed common bile duct (CBD) and pancreatic duct dilation. The abdominopelvic computed tomography (CT) scan showed a poorly-enhancing mass in the periampullary region. CONCLUSION: The patient's facial hyperpigmentation and hypokalemia appear to have been due to ACTH ectopic syndrome as a result of periampullary cancer.
