Introduction: Vitamin D deficiency is a common clinical finding in the general population and hospitalized patients, including patients in the intensive care unit (ICU). Acute kidney injury (AKI) occurs in more than 50% in ICU admitted patients. Objectives: There are few studies regarding AKI in COVID-19 patients, therefore we investigated the relationship between vitamin D3 deficiency and the occurrence of AKI in COVID-19 patients. Patients and Methods: This cross-sectional study was conducted on 69 COVID-19 patients who were hospitalized in the ward for 12 months. Their serum vitamin D3 levels were measured in the first 24 hours of hospitalization in the ward. Patients were divided into three groups based on the serum levels of vitamin D3: >50 ng/mL as normal, 20-50 ng/mL as insufficient and 50 ng/mL. The frequencies of AKI in groups of vitamin D350 ng/mL were 46%, 28%, and 23%, respectively. A significant relationship was observed between AKI and our study groups (P=0.011). Furthermore, there was a significant association between our study groups and mortality (P=0.014), ICU admission (P=0.041) and hospital length of stay (P=0.017). In another division in patients with different levels of vitamin D3 in the presence or absence of AKI, there were significant associations between patients with vitamin D3

The high risk of lipid abnormalities in type 2 diabetic (T2D) patients with uncontrolled hyperglycemia may be associated with an increased risk of cardiovascular complications. The aim of the current study was to investigate the association between glycated hemoglobin )HbA1c( and lipid profile levels in T2D patients. This cross-sectional study was conducted on 802 T2D patients, aged≥ 40 years, visiting the Abu Reyhan Clinic of Shahid Mohammadi Hospital in Bandar Abbas, Iran. Serum lipid profiles were measured by the enzymatic method. Diabetes was defined based on the criteria of the American Diabetes Association. The association of HbA1c and estimated glomeruli filtration rate (eGFR) with lipid profile indices was assessed using the Spearman correlation coefficient test and linear regression model. The mean±SD age of participants (27.7% of men) was 53.55±5.56 years. The mean±SD of HbA1c and eGFR for all subjects were 8.97±2.14 and 86.30±17.48, respectively. In this study,a positive association was observed between HbA1c and fasting blood glucose (r=0.619, β=0.635), total cholesterol (r=0.165, β=0.188), triglycerides (r=0.103, β=0.095), and low-density lipoprotein cholesterol (r=0.162, β=0.173), (P

COVID-19 may have various radiological manifestations on the patient’s chest computed tomography (CT) scan. Few cases with COVID-19 and pneumomediastinum have been reported to date. Here we present a patient with COVID-19, pneumomediastinum and emphysema.

Introduction: Kidney transplant is one of the treatments in patients with ESRD (end stage renal disease) that increases the quality of life in patients. Following kidney transplant, patients need glucocorticoid and immunosuppressant drugs. These drugs put patients in risk of hip avascular necrosis. The purpose of this study was to evaluate the prevalence of asymptomatic avascular necrosis of the hip in patients with kidney transplantation. Methods: This prospective descriptive cross-sectional study was conducted on all patients referred to the Shahid Mohammedi Hospital, Bandar Abbas, Iran, who had a kidney transplant at least six month before our study. All patients’ information was collected with a questionnaire consisting of demographic information including age, sex, weight, height, history of hemodialysis, history of peritoneal dialysis, history of smoking, alcohol intake, history of prednisolone and the main variable data of the disease, including the causes of ESRD such as diabetes, hypertension and diabetes combined, polycystic kidney disease, IgA nephropathy reflux disease, focal segmental glomerulonephritis and time elapsed after the transplant. Magnetic resonance imaging (MRI) was used for the detection of avascular necrosis. Diagnosis of avascular necrosis was confirmed by two separate radiologists. Data was analyzed using IBM SPSS 21.0 software. Results: In this study, 83 patients were studied. Among these patients, 45 (54.2%) were male and 38 (45.8%) were female. The average age of the subjects was 41.29 ± 13.72 years. Demographic variables were similar in two groups. There was no relation among the vertebrae and overall results densitometry with avascular necrosis (p>0.05). Based on this chart, prevalence of avascular necrosis in patients with osteoporotic hip based on densitometry, was significantly more than other people (p = 0.008). Conclusion: According to results, prevalence of femoral head avascular necrosis is not higher in patients after transplant and it has no significant relation to age, sex, BMI, time passed after transplant, CMV infection, hospitalization, history of dialysis or type of donator. Also, there was no significant correlation between the vertebra densitometry and the overall results of densitometry with avascular necrosis on MRI. The only factor associated with avascular necrosis in this study, was osteoporosis in the hip densitometry.
