Epidural dexamethasone for postoperative analgesia in patients undergoing unilateral inguinal herniorrhaphy: A comparative study

Background. This study was designed to evaluate the effect of adding dexamethasone to epidural bupivacaine on postoperative analgesia in unilateral inguinal herniorrhaphy. Methods. Forty-four patients were enrolled in this double-blind, clinical trial study. Patients were randomly allocated into dexamethasone or control group. In the dexamethasone group, patients received 18ml of bupivacaine 0.5% and 2ml (8mg) of dexamethasone; in the control group, patients received 18ml of bupivacaine 0.5% and 2ml of normal saline. The onset of sensory block and its duration and incidence of nausea and vomiting were recorded. Results. The onset of epidural anesthesia was significantly more rapid in the dexamethasone group than in the control group (P < 0.001). Duration of analgesia was markedly prolonged in the dexamethasone group than in the control group (P < 0.001). Five patients (22.7%) in the control group had nausea in the first hour after the procedure (P = 0.048). None of the patients in the dexamethasone group had nausea. None of our patients had vomiting in the two groups. Conclusions. This study showed that adding dexamethasone to bupivacaine significantly prolongs the duration of postoperative analgesia

Critical Content Analysis of Narrative Version of Islamic Medicine

Background and Objective: The nature of Narrative version of Islamic medicine (NIM) is based on Quran and hadith, exclusive attention to Islamic narrative references and rejection of the strategies of other medical schools. This study was conducted to criticize NIM. Methods: In this qualitative study of content analysis, after collecting the opinions of 6 prominent scholars of NIM, the criticisms of these opinions were presented and categorized by three doctors specialized in Persian medicine, a cleric in the field of Islamic jurisprudence and a methodologist by holding expert panel meetings. Findings: Criticisms were raised based on three points of view. The intra-religious area including the routine of Ahl al-Bayt (The holy family of the Prophet Muhammad) in illness and the role of physicians, the place of reason and experience in Islamic sciences, differences in geographical areas, not mentioning the full history of patients and newly occurring diseases was brought up. From a medical point of view, the important points include lack of a research method to check the effectiveness of a medical narrative, lack of diagnostic aspects and an approach to screening. From the viewpoint of religious and social consequences, religious trauma resulting from lack of response to treatment attributed to Ahl al-Bayt, approach to other manifestations of Western civilization, ethical issue of producing, prescribing and selling drugs by a group and loss of life and money due to waste of time in cases with definitive or relative treatment was raised in other medical schools. Conclusion: Based on the results of this research, the introduction of this theory to society without sufficient investigations in the seminaries and universities of medical sciences may cause physical, mental and religious trauma at the individual and social level

Full-length human placental sFlt-1-e15a isoform induces distinct maternal phenotypes of preeclampsia in mice

<div><p>Objective</p><p>Most anti-angiogenic preeclampsia models in rodents utilized the overexpression of a truncated soluble fms-like tyrosine kinase-1 (sFlt-1) not expressed in any species. Other limitations of mouse preeclampsia models included stressful blood pressure measurements and the lack of postpartum monitoring. We aimed to 1) develop a mouse model of preeclampsia by administering the most abundant human placental sFlt-1 isoform (hsFlt-1-e15a) in preeclampsia; 2) determine blood pressures in non-stressed conditions; and 3) develop a survival surgery that enables the collection of fetuses and placentas and postpartum (PP) monitoring.</p><p>Methods</p><p>Pregnancy status of CD-1 mice was evaluated with high-frequency ultrasound on gestational days (GD) 6 and 7. Telemetry catheters were implanted in the carotid artery on GD7, and their positions were verified by ultrasound on GD13. Mice were injected through tail-vein with adenoviruses expressing hsFlt-1-e15a (n = 11) or green fluorescent protein (GFP; n = 9) on GD8/GD11. Placentas and pups were delivered by cesarean section on GD18 allowing PP monitoring. Urine samples were collected with cystocentesis on GD6/GD7, GD13, GD18, and PPD8, and albumin/creatinine ratios were determined. GFP and hsFlt-1-e15a expression profiles were determined by qRT-PCR. Aortic ring assays were performed to assess the effect of hsFlt-1-e15a on endothelia.</p><p>Results</p><p>Ultrasound predicted pregnancy on GD7 in 97% of cases. Cesarean section survival rate was 100%. Mean arterial blood pressure was higher in hsFlt-1-e15a-treated than in GFP-treated mice (∆MAP = 13.2 mmHg, p = 0.00107; GD18). Focal glomerular changes were found in hsFlt-1-e15a -treated mice, which had higher urine albumin/creatinine ratios than controls (109.3±51.7μg/mg vs. 19.3±5.6μg/mg, p = 4.4x10^-2; GD18). Aortic ring assays showed a 46% lesser microvessel outgrowth in hsFlt-1-e15a-treated than in GFP-treated mice (p = 1.2x10^-2). Placental and fetal weights did not differ between the groups. One mouse with liver disease developed early-onset preeclampsia-like symptoms with intrauterine growth restriction (IUGR).</p><p>Conclusions</p><p>A mouse model of late-onset preeclampsia was developed with the overexpression of hsFlt-1-e15a, verifying the <i>in vivo</i> pathologic effects of this primate-specific, predominant placental sFlt-1 isoform. HsFlt-1-e15a induced early-onset preeclampsia-like symptoms associated with IUGR in a mouse with a liver disease. Our findings support that hsFlt-1-e15a is central to the terminal pathway of preeclampsia, and it can induce the full spectrum of symptoms in this obstetrical syndrome.</p></div

Effects of saffron supplementation on oxidative/antioxidant status and severity of disease in ulcerative colitis patients: A randomized, double-blind, placebo-controlled study

Supplementation with saffron helps improve antioxidant status. Oxidative stress plays an important role in ulcerative colitis (UC). The present study aimed to investigate the effect of saffron supplementation on disease severity and Oxidative/Antioxidant factors in patients with UC. This randomized double-blinded study was conducted on 80 mild to moderate UC patients. Participants were randomly divided into intervention (100 mg saffron/daily) and placebo (100 mg maltodextrin/daily) groups. Of all the participants, 75 completed the study. After 8 weeks, there were significantly increased in the mean score of simple clinical colitis activity index questionnaire (3.83 ± 1.78 to 3 ± 1.60, p =.004), the serum levels of total antioxidant capacity (2.68 ± 0.90 to 2.79 ± 0.87, p =.016), superoxide dismutase (60.69 ± 9.59 to 66.30 ± 10.79, p =.009) and glutathione peroxidase (22.05 ± 14.27 to 29.67 ± 17.97, p =.011) in patients received saffron compared to the placebo group. Whereas, there was no significant difference in serum levels of malondialdehyde between the two groups. Finally, dietary saffron as an alternative therapy may effective in improving antioxidant factors and reducing the severity of disease in UC patients. © 2020 John Wiley & Sons Lt

The effect of melatonin supplementation on lipid profile and anthropometric indices: A systematic review and meta-analysis of clinical trials

Background: Epidemiological evidence suggests that melatonin has some effects on the serum lipid. However, these results are controversial. The aim of this systematic review and meta-analysis is to examine the effect of melatonin supplement on dyslipidemia and anthropometric indices. Methods: We searched electronic databases including Medline, Embase, Scopus, Web of Science and Cochrane Library up to Des 2018 without any language restriction. To compare the effects of melatonin with placebo, differences in standardized means difference (SMD) with 95 confidence intervals (95 CI) were pooled using random effects model. Results: Twelve trials including 641 participants included in meta-analysis finally. The dose of melatonin was reported at 0.8�30 mg. Comparing with the control group, melatonin may improve low density lipoprotein cholesterol (LDL-C) (�0.31 mmol/L, 95 CI (�0.61, 0.01), P = 0.049, I2 = 42) and triglyceride (TG) level (SMD = �0.45 mmol/L; 95 CI, �0.77, �0.13, P = 0.006, I2 = 47). No significant effect of melatonin on high density lipoprotein cholesterol (HDL-C) and anthropometric indices was found. Conclusions: The results of our systematic review and Meta-analyzes showed that supplementation of melatonin could be effective in improving lipid parameters and should be considered in the prevention of cardiovascular disease, although the effect of this supplement on anthropometric indices needs further investigation. © 2019 Diabetes Indi

High-Velocity Oxy-Fuel (HVOF) Spray Coating of Inconel, Colmonoy, and Aluminum on AISI 316L Stainless Steel: A Comparative Investigation of the Microstructure and Corrosion Resistance of Coatings

This study examines the effect of high-velocity oxy-fuel (HVOF) coatings of Inconel, aluminum, and Colmonoy on the corrosion resistance of stainless steel substrates. The coated samples were characterized using SEM, XRD, and EDS techniques. Impedance and Tafel tests were used to investigate the coatings corrosion responses at 40, 50, and 60 °C. Inconel-coated specimens showed superior corrosion behavior thanks to the Cr2O3 layers formed between the lamella structures of the coating, preventing chloride ions from diffusing across the coating. Although the Nyquist curve indicated oxide layer formation for the Al-coated sample, the Tafel test results showed severe corrosion
