Objective: Osteoarthritis is a degenerative disease of the joints. Non-steroidal antiinflammatory drugs (NSAIDs) are being used for the treatment of osteoarthritis. However, their use is limited due to complications, such as gastrointestinal bleeding. Therefore, it is necessary to find alternative treatments for osteoarthritis. Recently, nanomicelle curcumin has been developed to increase the oral bioavailability of curcumin. The aim of this study was to evaluate the effect of nano curcumin on the alleviation of the symptoms of knee osteoarthritis patients. Methods: In this randomized, double-blind controlled trial, the intervention group was administered 40 mg of nanocurcumin capsule every 12 hours over a period of six weeks, and the control group received the placebo (similar components of nanomicelle curcumin capsules yet without curcumin). In the final analysis, 36 patients in the nanocurcumin group and 35 patients in the placebo group were enrolled. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was filled for patients in their first visit and at the end of six weeks. Differences were statistically significant at P-value < 0.05. Results: There were no significant differences between the two groups regarding gender, age, Kellgren score, and the duration of the disease before the intervention. A significant decrease was observed in the overall score, along with the scores of pain, stiffness and physical activity subscales of the WOMAC questionnaire in patients of the nano curcumin group compared with the placebo group. Conclusion: Nanocurcumin significantly improves the symptoms of osteoarthritis patients.

Monogenic diabetes mellitus (eg, Wolcott‐Rallison syndrome) is a rare condition. It associates with neonatal or early‐infancy insulin‐dependent diabetes. We reported DKA in the four‐month infant as the first presentation of monogenic diabetes that has accelerated by COVID‐19 infection. Therefore, considering the concurrency of COVID‐19 and DKA is crucial.
BACKGROUND One of the earliest diagnostic signs of hepatorenal syndrome in patients suffering from liver cirrhosis is an increase in the renal vascular resistive index (RI). In this study, the impact of propranolol on decreasing this index and to postpone the probability of hepatorenal syndrome has been investigated. METHODS In the current research, 30 patients with liver cirrhosis with different age and sexes have been enrolled. Demographic data and complete medical history have been collected using a specific questionnaire. At first, renal artery Doppler ultrasonography was performed to determine the RI. The patients were then treated with propranolol, and under supervision, the dose of the drug was increased gradually every 3 to 5 days to reach the target of 25% decrease in resting heart rate. One month after reaching the target dose of the medicine, Doppler ultrasonography was repeated for the patients and the second RI was compared with the pretreatment ones. RESULTS According to our results after treatment with propranolol, a significant decrease of RI was observed ( p < 0.01). However, there was no significant difference in the glomerular filtration rate (GFR) before and after treatment with propranolol ( p = 0.290). In our study, we found that administering propranolol was associated with significant changes in RI and GFR between the patients with compensated and decompensated cirrhosis (mean change: -0.005 ± 0.017 vs. -0.058 ± 0.045; p < 0.01 for RI and -4.226 ± 17.440 vs. 13.486 ± 12.047; p < 0.01 for GFR in patients with compensated and decompensated cirrhosis, respectively). CONCLUSION Propranolol reduces renal vascular RI in patients with cirrhosis. The response rates in the patients with decompensating cirrhosis were significantly higher than the patients with compensating cirrhosis
