Efficacy of Fish Oil in Rheumatoid Arthritis
B Heidari, Sh Rezaeemajd, A Makaremi,
Volume 56, Issue 1 (30 1998)
Abstract

Ingestion of fish oil fatty acids (omega - 3 fatty acids ) inhibits the formation of arachidonic acid - derived cytokines and leads to production of compounds with diminished biological activity. Beneficial effects of dietary supplementation with fish oil in rheumatoid arthritis have been shown in many controlled trials.
Methods : 43 patients with active rheumatoid arthritis entered in a prospective, double-blind, placebo-controlled clinical trial to recieve either lOgr fish oil daily (treatment group) or corn oil (placebo group). Baseline drugs and usual diet were continued without any changes. Disease variables were evaluated at baseline and after completion of study period.
The changes in disease variables were compared by paired t-tesl in each group. Comparison of the two groups was done by t-test. Functional capacity was compared by Wilcoxon ranks test.
Results : 19 patients in treatment group and 20 patients in placebo group completed the study which lasted eight weeks . In the treatment group, joint pain index decreased from 30±11 at baseline, to 18±11 at the end of study period (P < 0.01). Joint swelling index decreased from 8 ± 4 to 2 ± 4, (P< 0.01), morning stiffness from 87 ± 41 to 24±16 minutes (P < 0.01). In the placebo group the above variable changes were from 19±14 to 25±14 8±8 to 7±6 and 80±71 to 76±75 minutes respectively, which were not significant . The differences between the treatment and placebo groups were significant in joint swelling index (P < 0.05), morning stiffness (P<0.01) and functioal capacity (p< 0.005), the differences in joint pain index and grip strenght did not quite achieve statstical significance. During study period there were no adverese effects with fish oil consumption.
Conclusion : Fish oil supplemention has anti-inflamatory effects in rheumatoid arthritis. Further studies are needed to recommend its long - term usage concomittant with other drugs in all patients

Volume 69, Issue 12 (5 2012)
Abstract

Background: Nowadays, cancer is one of the main causes of mortality in the world and many mutagens are the cause of death in millions of patients. Due to the side effects of anticancer drugs, scientists are in search of natural drugs with fewer side effects and more therapeutic efficacy. This study aims to, firstly, investigate the antimutgenic effects of different Aloe vera gel and latex extracts on mutated Salmonella typhimurium bacterium by using Ames test and to, secondly, study the probable effects of the habitat conditions on the antimutagenic effects of the plant.

Methods: After preparing different Aloe vera gel and latex extracts, the antimutagenic effects of the extracts were evaluated by Ames test. In this test, a mutated strain of S. typhimurium was grown on culture media containing a minimum of salt and glucose in the presence of a mutagen substance (NaN3). Subsequently, only those bacteria that had turned HIS+ by reverse mutation formed colonies. As different alcoholic and aqueous extracts of Aloe vera reduced reversed mutations, the difference between the means of revertant mutants per plate was calculated by one-way ANOVA using SPSS software (version 18).

Results: The ethanol extracts of latex from Karaj had a maximum (91%) and aqueous extract from Dezfoul had a minimum (42%) percentage of inhibition.

Conclusion: Maximum percentage of inhibition was observed in the extracts of the plant cultivated in Karaj reflecting the impact of environmental conditions on the construction of antioxidant compounds in plants.

Abstract
Background: Everolimus is an immunosuppressive agent with a novel mode of action but has a different clinical role with calcineurin inhibitors (CNI). The aim of this study was to evaluate the safety and effectiveness of everolimus compared with sirolimus and tacrolimus in preventing kidney transplantation rejection. Methods: Search was conducted for finding randomized clinical trials (RCT) until the end of 2013 in main databases include Cochrane, Medline and other related databases in February 2014. To find the ongoing trials two databases were searched (Clinicaltrial.gov and irct.ir/fa/). Two independent reviewers checked studies for quality and eligibility and finally extracted the data. Data extraction was performed using Cochrane data extraction form for clinical trial. Discrepancies were resolved via consultation with third person. The studies examined in term of heterogeneity with I2 and Chi-square test. The mata-analysis was carried out using RevMan 5.2 (Wintertree Software Inc, Ontario, Canada) when there was homogeneity. Results: Finally, seven reports from six RCTs included in this study. All reports were in english language and total numbers of participant in these studies were 824. No studies were found in comparison of everolimus and sirolimus and all seven reports were combination of everolimus, tacrolimus and other relative drugs. Follow up time of studies were different from 6 to 36 months. Due to the heterogeneity of included studies, only two studies were entered into meta-analysis. The recorded mean values for glomerular filtration rate, serum creatinine and creatinine clearance were between 60-80 ml/min, 50 to 80 ml/min and 1.2 to 1.9 mg/dl respectively. The results of meta-analysis in three outcomes include serum creatinine, creatinine clearance and glomerular filtration rate were significantly in favor of low dose tacrolimus plus everolimus. Conclusion: In general, everolimus showed better results in combination with tacrolimus. Given the available evidence in this study, everolimus in combination with low dose tacrolimus showed better safety and effectiveness in preventing kidney transplantation rejection.

Abstract

Background: Sexual dysfunction could be under the influence of some underlying medical problems. The purpose of this study is to examine the relationship between medical problems and sexual function in post-menopausal women.

Methods: This is a community-based, descriptive-correlation study of 405 post-menopausal women residing in Chalus and Nowshahr cities, North of Iran, aged 40 to 65 years old from October 2013 to May 2014. A multistage, randomized sampling was conducted. The data was acquired through interviews using the Female Sexual Function Index (FSFI) questionnaire and a researcher-made questionnaire, and was analyzed using descriptive and analytical tests such as multiple linear regression and logistic regression models.

Results: 51.4% of the subjects had medical conditions. Cardiovascular disorders were the most common diseases among the subjects. 61% of the women were suffering from female sexual dysfunction (FSD). Sexual dysfunction in patients with medical conditions was significantly higher (P= 0.037). Scores of arousal (P= 0.000), orgasm (P= 0.018), and satisfaction (P= 0.026), as well as the FSFI total score (P= 0.005), were significantly lower in subjects with cardiovascular disorders. Scores of desire (P= 0.001), arousal (P= 0.006), lubrication (P= 0.010), orgasm (P= 0.004), and satisfaction (P= 0.022), as well as the FSFI total score (P= 0.017), were significantly lower in subjects with diabetes. Scores of pain were significantly lower in subjects with musculoskeletal disorders (P= 0.041), they experienced more pain during intercourse. In domains of arousal (P= 0.030), satisfaction (P= 0.040), and pain (P= 0.044), the scores of those taking antihypertensive medications were significantly lower than the scores of the rest of the subjects. Scores of desire (P= 0.001), arousal (P= 0.006), orgasm (P= 0.006), and satisfaction (P= 0.048), as well as the FSFI total score (P= 0.006), were significantly lower in those taking antidiabetic drugs. And lastly, the mean satisfaction score in women whose spouse had medical conditions was significantly lower (P= 0.040).

Conclusion: Cardiovascular disorders, diabetes, and musculoskeletal disorders could have a negative impact on sexual function in post-menopausal women. Thus, these diseases must be considered and treated in order to improve women’s health, particularly their sexual function.

Abstract
Background: 2-phenylethanol is a colorless and aromatic compound with antimicrobial effects which is used extensively in perfumes and cosmetics, as well as in the food industry. Chronic vulvovaginal candidiasis is a vulvovaginal inflammation which is caused by Candida spp. Resistance to clotrimazole which is one of the most common drugs in the treatment of this disease was reported in many patients. In order to improve the treatment, the effect of 2-phenyl ethanol was investigated in combination with clotrimazole on Candida species isolated from chronic vulvovaginal candidiasis.
Methods: This interventional study was performed in Iran University of Medical Sciences from February, 2016 until December, 2016 on Candida species isolated from women with chronic candidial vulvovaginitis who had been referred to Lolagar Hospital of Tehran. All specimens were examined by direct microscopy, culturing on Candida CHROMagar medium (to primary identification), sabouraud dextrose agar medium) to preservation the isolates) and determining the internal transcribed spacer (ITS) sequence (in order to final determination of Candida species). Then clotrimazole and 2-phenyl ethanol alone and in combination, was examined on isolated species, according to Clinical and Laboratory Standards Institute (CLSI) M27-A3 protocol (micro-broth dilution method). Finally, findings were analyzed.
Results: From 40 detected strains of Candida species in this study, 95% were Candida albicans and 5% were Candida africana. The mean minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) of clotrimazole were 24.73±28.87 µg/ml and 30.18±33.004 µg/ml, respectively and the mean MIC and MFC of 2-phenylethanol were 2580±932.38 µg/ml and 3200±1403.29 µg/ml, respectively. The MIC50 and MIC90 of clotrimazole were 16 and 64 µg/ml, respectively. The MIC50 and MIC90 of 2-phenylethanol were both 3200 µg/ml. Most of the isolates were resistant to clotrimazole (82.5%). In combination test, the mean MIC of 2-phenylethanol and clotrimazole alone were 3200±0 µg/ml and 56±40.16 µg/ml, respectively. The fractional inhibitory concentration index (FICI) range was 0.14-0.37. Also, there was a significant difference between clotrimazole MIC values alone and in combination (P= 0.021).
Conclusion: The synergistic effect was observed in combination of clotrimazole and 2-phenylethanol.

Volume 75, Issue 12 (March 2018)
Abstract
Thyroid cancer is one of the most common endocrine malignancies and in the last two decades the number of involved people in the world has been increased. Thyroid cancer in Iran is the seventh most common cancer in women and 14th in men. In recent years many achievements regarding to molecular pathogenic factors such as the substantial role of signaling pathways and molecular abnormalities have been made. Nowadays there is no efficient treatment for progressed thyroid cancer that does not respond to radioiodine therapy which are included poorly differentiated, anaplastic and metastatic or recurrent differentiated thyroid cancer. Although the results of some clinical trials in phase II for treatment of progressed thyroid cancer are rewarding but none of the treated patients responded to treatment and only a few of them responded partially to the treatment which indicates that the treatment can only control the condition of patients with advanced disease, therefore it is needed to consider other alternative solutions which would be helpful in controlling the disease. Epigenetic is referred to study of heritable changes in gene expression without changes in primary DNA sequence. The main mechanisms of genetic and epigenetic alterations are including mutations, increasing the gene copy number and aberrant gene methylation. Epigenetic defects are prevalent in different types of cancers. Aberrant methylation of genes that control cell proliferation and invasion (p16INK4A, RASSF1A, PTEN, Rap1GAP, TIMP3, DAPK, RARβ2, E-cadherin, and CITED1), as well as specific genes involved in differentiation of thyroid cancer (Na+/I- symport, TSH receptor, pendrin, SL5A8, and TTF-1) in association with genetic alterations, leads to tumor progression. Growing evidence shows that acquired epigenetic abnormalities participate with genetic alterations to cause altered patterns of gene expression or function. Many of these molecular changes can be used as molecular markers for prognosis, diagnosis and new therapeutic targets for thyroid cancer. This article is about the most common genetic and epigenetic alterations in thyroid cancer which can be complementary together in recognition of new treatments for the disease.

Volume 78, Issue 11 (February 2021)
Abstract
Background: Infection is a vital problem in intensive care units. Currently, chlorhexidine solution is used to reduce oral colonization. This study aimed to determine the efficacy of chlorhexidine solution on oropharyngeal bacterial colonization in hospitalized patients in the intensive care units.
Methods: This descriptive study (from August 2018 to May 2019) was performed on 60 patients who administered in medical and surgical intensive care units (ICUs) in one of the university hospitals in Semnan city. Patients admitted to (ICUs) were selected according to inclusion criteria. At the time of admission to the intensive care unit, oropharyngeal colonization of patients was assessed. Forty-eight hours after admission and using the chlorhexidine solution 0.2% three times a day, oropharyngeal colonization was assessed again. Data analysis was performed with SPSS software, version. 22 in the significant level of 0.05.
Results: This study showed most of the patients in this study were male (80%) with mean age of 45.23±15.19 years. Most patients were transferred from the emergency department to intensive care units and had endotracheal tubes. At the time of admission to the intensive care unit, 8 patients were infected with E. coli and 6 patients were infected with Klebsiella. The results also showed that the use of chlorhexidine 0.2% had no significant effect on the reduction of micro-organisms in the oropharyngeal area. Forty-eight hours after admission to ICUs, the incidence of E. coli infection increased (P=0.01) but there was no significant increase in the klebsiella infection rate (P=0.25).
Conclusion: This study showed that the use of chlorhexidine solution 0.2% did not affect the reduction of micro-organisms in the oropharyngeal areas of patients. Therefore, oral care protocols that include mechanical movements and toothbrushing should be considered to reduce the occurrence of micro-organisms. This study also found that most patients who were referred to the intensive care unit were contaminated with pathogenic micro-organisms. Therefore, consideration should be given to appropriate strategies to reduce infections in the emergency department.

Evaluation of the effect of using platelet-rich fibrin in healing wounds caused by fistulas with supralevator collection and its effect on fistula recurrence
Mehdi Alemrajabi, Seyed Hamze Musavi , Behrouz Seydi Majd , Tayeb Ramim,
Volume 80, Issue 2 (May 2022)
Abstract
Background: Supralevator abscesses make up to 9% of all cryptoglandular abscesses. Given that platelet-rich fibrin accelerates tissue growth and reduces infection, it seems necessary to investigate its effect on the healing of fistula wounds because it can accelerate the healing of morbid wounds and reduce its effect on recurrence.
Methods: The study was performed as a single-blind clinical trial in patients who were referred to the surgical clinic of Rasoul Akram Hospital (PBUH), with the approval of the supralevator collection. Before surgery, Wexner Score were identified in patients who underwent surgery, and the entire path of fistulas and cavities was identified. Clinical outcomes were monitored one day after surgery for up to two months once a week, then every month until complete recovery, and then six months after surgery. After the operation, the patients were examined for recurrence, until the PRF was absorbed, the dressing of the operation site was performed only with normal saline, and the patients were on a low-residue diet so that they could not excrete as much as possible.
Results: 10 people participated in the final analysis. The mean age of patients was 33.20 years (26-46 years). Three patients had a history of perianal abscess surgery, two patients had a history of fistula surgery and 1 patient had a history of Fisher surgery. The mean closing time of the cavity was 14.2 days (10-22 days). Two patients (20%) had a fever and two patients (20%) had a surgical site infection. Bleeding and recurrence were not observed in any of the patients. The mean preoperative Wexner score was 0.80±0.76 Which decreased to 0.68±0.50 postoperatively (P=0.045).
Conclusion: Finally, the findings of the study showed that the use of PRF to repair a complex fistula is a method that can be easily repeated with minimal side effects and can heal wounds caused by fistulas with supralevator collection. This treatment can play an important role in the treatment of complex fistulas that have moderate or extensive involvement with the sphincter, or the occurrence of fistulas with sphincter dysfunction.
