Page 1BackgroundMetabolic control is a major concern in preventing diabetic complications. Sa?ron as a natural source of antioxidants could play a role in alleviating diabetes insults. Te aim of this study was to investigate e?ect of sa?ron hydroalcoholic extract on metabolic control in type 2 diabetes (T2D) mellitus.Materials And MethodsTis randomized triple blind study was included 54 T2D patients which randomly received either sa?ron (Group 1) or placebo (Group 2) twice daily other than routine antidiabetic treatments for 8 weeks. Serum concentration of fasting blood sugar (FBS), 2?h plasma glucose, hemoglobin A1c (HbA1c), total cholesterol, triglyceride (TG), low?density lipoprotein, and high?density lipoprotein were measured as the markers of metabolic control. Anthropometric measures and blood pressure were also measured at the baseline, every 2 weeks during the intervention and the end of the study. Data analyzed using repeated measure analysis of variance test.ResultsTe baseline metabolic parameters were the same in two group (P > 0.01). FBS serum level signifcantly decreased within 8 weeks in the sa?ron group (128.84 ± 31.86) as compared to the placebo (153.76 ± 41.23), (P 0.01).ConclusionSa?ron hydroalcoholic extract may improve blood glucose control by reducing FBS in T2D patients. However, sa?ron extract has no signifcant e?ect on other aspects of diabetic control in diabetic patients.Keywords: Diabetes mellitus, fasting blood glucose, lipid, metabolic syndrome, sa?ron extract

Page 2BackgroundRenal colic is a painful medical emergency, needs urgent intervention to reduce pain. Nonsteroidal anti?in?ammatory drugs, opioids, and entonox are pain?relieving agents. Tis study was aimed to compare fentanyl entonox (nitrous oxide O2) versus fentanyl oxygen.Materials And MethodsOne hundred and twenty patients with acute renal colic presenting to the emergency department were enrolled. First, 50 µg fentanyl was infused for all patients. Ten, patients divided into two groups receiving masks of entonox and oxygen, respectively. Quantitative measurement of pain was performed by visual analog scale, before the intervention, after 3, 5, 10, and 30 min of that. If the pain was not relieved after 30 min, 50 µg fentanyl was infused. If the pain was still continued, ketorolac and ketamine were used. Hospitalization duration and severity of pain at specifed times were compared between patients in two groups.ResultsTe mean (standard deviation) time of hospitalization was 211 (59) and 236 (61) min in fentanyl entonox and fentanyl O2 groups, respectively (P = 0.024). Te decrease in pain severity after 10 and 30 min in fentanyl entonox group were signifcantly greater than fentanyl O2 group (P = 0.002 and 0.001, respectively). Mean (standard error) of needed time for renal colic pain to get better was 11.27 (1.23) and 20.47 (1.71) min in fentanyl entonox and fentanyl O2 groups, respectively (PConclusionEntonox is more e?ective to decrease the duration of hospitalization and reduction of pain than O2 in renal colic patients.Keywords: Fentanyl, nitrous oxide, oxygen, renal colic

Page 3BackgroundGenetically, predisposed children are considered as at?risk individuals for cardiovascular disease. In this study, weaimed to compare the frequency of four?lipid regulatory polymorphism in obese and normal?weight children with and withoutcardiometabolic risk factors.Materials And MethodsIn this nested casecontrol study, 600 samples of four groups of participantsconsisted of those with normal weight with and without cardiometabolic risk factors and obese with and without cardiometabolic risk factors. Allelic and genotypic frequencies of GCKR (rs780094), GCKR (rs1260333), MLXIPL (rs3812316), and FADS (rs174547)polymorphisms were compared in the four studied groups.ResultsData of 528 samples were complete and included in this study.
Te mean (standard deviation) age of participants was 15.01 (2.21) years. Frequency of tt allele (minor allele) of GCKR (rs1260333)polymorphism was significantly lower in normal weight metabolically healthy participants than metabolically unhealthynormal weight (MUHNW) and obese children with and without cardiometabolic risk factor (P = 0.01). Frequency of ga allele ofGCKR (rs780094) polymorphism was signifcantly higher in normal weight children with cardiometabolic risk factor than in theirobese counterparts with cardiometabolic risk factor (P = 0.04). Frequency of cg and gg alleles (minor type) of MLXIPL (rs3812316)polymorphism in normal weight metabolically healthy participants was signifcantly higher than MUHNW (P = 0.04) and metabolicallyhealthy obese children (P = 0.04).ConclusionTe fndings of our study indicated that the minor allele of GCKR (rs1260333)single nucleotide polymorphisms (SNPs) could have pathogenic e?ect for obesity and cardiometabolic risk factors. Ga allele of
GCKR (rs780094) SNPs had a protective e?ect on obesity. Minor alleles of MLXIPL (rs3812316) could have a protective e?ect forobesity and cardiometabolic risk factors.Keywords: Children, fatty acid desaturases, glucokinase regulatory protein, metabolic syndrome, MLXIPL protein, obesity, polymorphism -
Page 4BackgroundWe aim to compare the degree of pain control and complications in three types of anesthesia using periprostatic nerve block (PPNB) plus intrarectal local anesthesia (IRLA), low?dose spinal anesthesia, and intravenous (IV) sedation in patients undergoing transrectal ultrasound (TRUS)?guided prostate biopsy.Materials And MethodsIn this clinical trial study, 106 patients were participated from December 2015 to December 2016 at Alzahra Hospital, Isfahan, Iran. Patients were randomly allocated into three groups to receive PPNB plus IRLA (n = 36), low?dose spinal anesthesia (n = 35) and IV sedation (n = 35) before TRUS?guided prostate biopsy. Pain scores were recorded using a 10 point visual analog scale right after the biopsy was done. Early and late complications were assessed using a questionnaire after the procedure and in follow?up of patients.ResultsOverall, the pain score in the low?dose spinal anesthesia group was signifcantly lower than PPNB plus IRLA and IV sedation groups (PConclusionTis study demonstrates that low?dose spinal anesthesia is superior to PPNB plus IRLA and IV sedation in terms of pain controlling and was associated with higher tolerance of the examination and patient comfort.Keywords: Intravenous sedation, nerve block, pain, prostate biopsy, spinal anesthesia, trans rectal ultrasonography

Page 7BackgroundNonmelanoma skin cancer (NMSC) in renal transplant recipients is common and associated with signifcant morbidity and mortality. Te aim of the present systematic review and meta?analysis was to estimate the incidence of NMSC among renal transplant recipients.Materials And MethodsWe systematically searched PubMed, Medline, Scopus, and Web of Science databases for studies that assessed the incidence of NMSC in renal transplant recipients using a combination of relevant keywords. Two independent investigators included studies and extracted necessary information. Random e?ect meta?analysis was used to estimate pooled incidence of NMSC with 95% confdence intervals (CIs).ResultsTwenty?nine studies comprising 36,021 patients meet the criteria for the systematic review. Te pooled incidence of NMSC in renal transplant recipients was 12.6% (95% CI: 12%14%) with a majority of squamous cell carcinoma (SCC) 55% (95% CI: 47%63%). Te pooled estimate of the incidence rates of SCC and basal cell carcinoma was 2.7% (95% CI: 2%3.4%) and 2.2% (95% CI: 1.5%2.8%), respectively. Subgroup analysis per geographic location showed that pooled incidence of NMSC was 39.1% (95% CI: 26.3%51.8%), 12.4% (95% CI: 8.8%16%), and 1.2% (95% CI: 0.4%2%) in Australia and New Zealand, Europe, and Middle East, respectively.ConclusionTe results of the current meta?analysis demonstrated that the incidence of NMSC in renal transplant recipients varies widely. Regarding the high incidence of NMSC among renal transplant recipients, awareness of associated risk factors and early diagnosis of the malignancy in the population is a major clinical need.Keywords: Basal cell carcinoma, incidence, nonmelanoma skin cancer, renal transplantation, squamous cell carcinoma
