T2DM can cause many micro or macrovascular complications. Metformin, a biguanides derivative, has multiple benefits except anti-hyperglycemia effect, comprising amelioration blood cholesterol levels, blood pressure and depressing vascular complications accompanied with T2DM. It is proposed that metformin act via adenosine monophosphate-activated protein kinase (AMPK) -dependent or -independent approaches. The mechanisms by which metformin regulates glycemic level in T2DM are complex. In addition to its peripheral effects on insulin resistance and glycogenesis, metformin has direct beneficial effect on the beta-cell secretion. A large part of the metabolic advantages of metformin can be related to effects on gastrointestinal glucose uptake and the interaction of metformin with numerous new objects for glucose depressing in the gastrointestinal tract, including the incretin receptors, bile salt transporters and the gut microbiota.","PeriodicalId":16964,"journal":{"name":"Journal of Renal Endocrinology","volume":"64 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78928586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, he was operated on by two teams of urology and heart surgery. The patient’s kidney was removed, and then he was subjected to sternotomy by the heart surgery team to remove the thrombus tumor. After opening the pericardium inside the pericardial cavity, a pericardial mass measuring 1×2 ×3 cm, which was connected to the lower surface of the aortic arch by a 1 cm long stalk, was observed. It was resected and sent to pathology laboratory. The rest of the surgery to remove the thrombus tumor from inside the right atrium and IVC continued according to the procedure. The pathological report was benign thyroid tissue. Actual cases of IPTH are underreported, and due to the small number, it is not yet possible to comment on the prevalence of malignancy in it or its functional role; However any lesion or abnormal mass in the pericardial cavity should be respected and sent to pathology laboratory therefore by collecting information about these masses, in the future, decisions can be made and summarized.","PeriodicalId":16964,"journal":{"name":"Journal of Renal Endocrinology","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79891916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several studies demonstrated the effect of ketamine in improving the analgesia using opioids, however, obese people reported different reactions to this problem. Objectives: This study seeks to answer the following question: Does adding ketamine to morphine in a patient-controlled intravenous analgesia pump (PCIA) after orthopedic surgeries help better management of postoperative pain in obese patients? Patient and Methods: This double-blinded clinical trial involved 60 obese (body mass of higher than 30 kg/m²) lower limb orthopedic surgery candidates at Shohada hospital (Tabriz, Iran). The participants were randomly categorized into three groups. In group M, 20 mg morphine sulfate, in group MK1 100 mg ketamine + 20 mg morphine sulfate, and in group MK2 200 mg ketamine+10 mg morphine sulfate was added to the analgesia pump. Pain intensity (VAS), sedation score (Ramsay Scale), as well as nausea and vomiting (N&V score) were compared among different groups at 12, 24, 36, and 48 hours after the operation. Results: Group M manifested a significantly higher pain intensity than two other groups during all examined times, and group MK2 demonstrated a significantly lower pain intensity than other groups. In the course of the research, the amount of opioid consumption in group MK2 was significantly lower than in the other groups. Conclusion: The addition of a low dose of ketamine to morphine in the PCIA pump after orthopedic surgeries in obese patients results in proper postoperative pain management.

The severity of the disease was determined using anemia, clinical complications, total white blood cells count, and scores of blood transfusion. To define different renal function phases, estimated glomerular filtration rate (eGFR) was computed in adults and children using the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) and Schwartz equations respectively. The ACE I/D polymorphism was conducted using polymerase chain reaction (PCR) and separation through agarose electrophoresis. Results: The risk of impaired renal function was not statistically distinct between ACE I/D genotypes and alleles. Further, the genotypes of ACE I/D and the risk of disease severity was not found to be associated with each other.

Antioxidants can neutralize free radicals and ROS thus possesses protective effect on the body. Plants are rich sources of natural antioxidants and phenolic compounds are among the most important antioxidants in the plants; therefore, many studies have investigated their protective effects. Objectives: This study was conducted to evaluate and compare the number of flavonoids, flavonols, and total phenolic compounds in 10 commonly used medicinal plants in Iran. Materials and Methods: Extraction was performed using 70% ethanol solvent. The extracts were concentrated by rotary evaporator at 40°C. Folin-Ciocalteu method was used to measure the amount of phenol. The amount of flavonol was measured using 2% aluminum chloride and 5% sodium acetate. In addition, to determine the flavonoid compounds, 2% aluminum chloride and 5% potassium acetate was used. Results: The outcomes of this study disclosed that the studied plants had reasonably high quantities of flavonoid and phenolic compounds. The uppermost amount of phenolic compounds was detected in the myrtle plant (62.7 mg/g), and the lowermost amounts were detected in fig leaves and lemon balm. Moreover, the highest amount of flavonoid compounds was detected in ginger, myrobalan, and myrtle; the measured amounts of flavonoid compounds in the mentioned plants were 42.49, 32.15, and 34.38 mg/g, respectively. The highest amount of phenolic compound was detected in hydroalcoholic extract of barberry. Conclusion: Hydroalcoholic extract of ginger, barberry, fig leaves, rhubarb, myrobalan, walnut diaphragm, pomegranate peel, lemon balm, cardamom, and myrtle had great quantities of phenolic, flavonol, and flavonoid compounds. As a result, these herbal plants can be considered and used as an important source of natural antioxidants.","PeriodicalId":16964,"journal":{"name":"Journal of Renal Endocrinology","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83234625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
