Context: Mindfulness-based interventions have shown promising therapeutic outcomes in improving well-being, mental health, general health, and quality of life; however, findings in this regard are inconsistent. The present study aimed at clarifying this in- consistency in the literature focusing on the Iranian studies through a systematic review and meta-analysis study. Evidence Acquisition: The databases of Pubmed, Scopus, Doaj, EBSCO, Iranmedex, MagIran, SID, and Comprehensive Human Sci- ences Portal, and additional resources were searched using the set terms of “mindfulness” OR “mindfulness-based cognitive thera- py” OR “MBCT” OR “mindfulness-based stress reduction” OR “MBSR” AND “intervention” AND “well-being” OR “health” OR “quality of life” and the time limit of the records was set between March 2008 and May 2017. The language of the search was restricted to English and Farsi. The studies that conducted on Iranian populations were selected in this review, only. Thirty-five studies conducted on 3013 subjects were assessed. Cochrane Q-test and I-squared index were used to detect the heterogeneity among results, and fixed effectmodel with a 95% Confidence Interval (CI) was applied. The effect size of mindfulness-based interventions on well-being, mental health, general health, and quality of life improvement, measured by Hedge‘s g ratios, were respectively 1.54, 1.08, 0.89, and 1.87. Results: The findings showed that the effect size of mindfulness-based interventions on well-being, mental health, general health, and quality of life improvement were of high magnitude, according to the Cohen’s table.Conclusion: Mindfulness-based interventions effectively improved well-being, health, and quality of life

Introduction: A hydatid cyst of the breast is an extremely rare condition caused by Echinococcus granulosus, even in endemic coun- tries, which accounts for 0.27% of all cases. Only a few reports have been published in the literature about breast hydatid cysts. Patients usually present with a palpable and painless lump in the breast. Clinically, it is difficult to differentiate breast hydatid cysts from more common breast lesions. However, imaging plays an important role, and often helps to distinguish this rare cystic disease of the breast from other breast masses. Case Presentation: Iran is an endemic area for Echinococcus granulosus, and we present six cases of primary breast hydatid cysts which were diagnosed over the course of 10 years in our institution. We aimed to present the mammographic and ultrasonographicfindings for these patients. Conclusions: Hydatid cysts should be considered in the diagnosis of cystic lesions of the breast, particularly in endemic areas

Background: There are several therapeutic strategies available from the viewpoint of Traditional Persian Medicine (TPM) to treat hepatic diseases. Objectives: This study aimed at assessing the efficacy and safety of Nigella sativa and Melissa officinalis in patients with Non-Alcoholic Fatty Liver Disease (NAFLD). Methods: From November 2014 to May 2016, in an open-label, simple-blocked, randomized controlled clinical trial, the researchers evaluated the efficacy of Nigella sativa and Melissa officinalis compared with Orlistat capsule on the grade of fatty liver and the serumlevels of Aspartate Transaminase (AST) and Alanine Transaminase (ALT) in 50 patients with NAFLD in Iran. Results: Regarding within-group changes, a significant decrease was observed in the serum level of AST, ALT, body mass index, and grade of fatty liver in both groups after the intervention compared with baseline (P < 0.001). Repeated measures logistic regression analysis showed that there was a more significant reduction in the grade of fatty liver over the study period in the intervention group compared with the control group (0.58 ± 0.50 versus 1.51 ± 0.54, P < 0.001).Conclusion: Traditional Persian Medicine-based preparations of Nigella sativa and Melissa officinalis could reduce body weight and liver enzymes and improves the grade of fatty liver in Non-Alcoholic Fatty Liver Disease

Background: Identification of reliable predictors of hypertension and prehypertension in each population is essential for early detection of at-risk people and also planning preventive strategies. Objectives: The present study aimed to assess the abilities of different indices of general and central obesity in the prediction of incident prehypertension and hypertension in a large population-based study in Iran. Methods: In this cross-sectional study, we evaluated the anthropometric and blood pressure measurements in 10,137 subjects (35 - 70 years) from Azar- Cohort study, north-west of Iran. Blood pressure was measured twice, with 10 minutes apart, from both upper extremities. Height, weight, waist, and hip circumferences measured according to the NIH guidelines. Hypertension considered as systolic blood pressure ≥ 140 and diastolic blood pressure ≥ 90 mmHg or current use of antihypertensive medication for manage- ment of hypertension. Results: The mean BMI (kg/m2), WC (cm), waist- to- hip ratio (WHR), and waist- to- height ratio (WHtR) were 28.75 ± 4.83, 94.69 ± 11.23, 0.90 ± 0.07, and 0.58 ± 0.07, respectively. The prevalence of prehypertension and hypertension were 16.3% and 23.3%, respectively. There was a significant association between prehypertension and hypertension with all included anthropometric indices in both men and women (All P < 0.001). In men, obesity increased the risk of prehypertension and hypertension by 3.13 (95% CI: 2.48 - 3.94) and 4.06 (95% CI: 3.23 - 5.10), respectively. In women with WHtR > 0.5 cm, the risk of hypertension increased by 6.27 (95% CI: 4.39 - 8.95) times. Conclusions: According to the result of this large population-based study, BMI is the best predictor of prehypertension and hyper-tension in men and also the waist- to- hip ratio combined with BMI were the best predictors of prehypertension and hypertension in women. These findings may have significant implications in using the most useful screening index for predicting hypertension in Iranian adults and also using waist- to- hip ratio for early detection of pre-hypertension

Background: Knee osteoarthritis is one of the most prevalent and disabling diseases worldwide, which decreases patients’ qual- ity of life (QoL). However, pharmacological and non-pharmacological treatments, apart from complications, could not desirably control the disease. Objectives: The current study aimed at evaluating the effect of two methods of intra-articular injection of Platelet-Rich Plasma (PRP) and corticosteroid on pain control of knee osteoarthritis. Methods: A randomized clinical trial was performed on 67- patients with grades II-III of knee osteoarthritis (OA) referring to painclinic of a referral, university-affiliated hospital, Rasht, Iran, from April 2016 to June 2017. Patients were randomly divided into two groups: Triamcinolone (T) (n=34) and PRP (P) (n=33) by quadruple block. In the group T, 40 mg Triamcinolone and in the group P, PRP was injected intra-articularly, under ultrasound- guidance, once a month, for three consecutive months. Patients’ pain intensity was evaluated based on the Visual Analog Scale (VAS), and their outcome was determined based on the Knee injury and Osteoarthritis Outcome Score (KOOS) monthly for three consecutive months, as well as six months after the treatment. Results: There were no significant differences between the groups regarding demographic characteristics. VAS assessments indi- cated lower pain scores in the group P than group T; the difference between the groups was statistically significant two, three, and six months after the injections. In the group P, the mean initial VAS was 7.36 ± 0.92 compared with 7.12 ± 1.29 in the group T (P = 0.385). After six months, the scores dropped to 3.45 ± 0.86 and 4.81 ± 1.4, respectively (P = 0.0001). Examination of the KOOS param- eters showed a significant association between treatment outcomes in the group P than the group T. Therefore, the test showed asignificant difference between the groups regarding relief of pain, improvement of symptoms and activities of daily living (ADL) two, three, and six months after treatment. There was also a significant difference between the groups in terms of the quality of life (QoL) and doing sport activities three and six months after the treatment (P < 0.05). Based on the repeated measures analysis, a significant inter- and intra-group differences in the mean score of KOOS parameters was observed between the intervals (P = 0.0001). Conclusions: The current study results showed that three intra-articular injections of Triamcinolone and PRP could reduce pain and improve articular function in patients with grades II-III knee osteoarthritis. However, pain relief and improvement in the outcomes were more effective and more prolonged secondary to PRP injections than corticosteroids.

Background: Increasing evidence implies that Adipocytokines may result in cardiovascular disease (CVD) events and metabolic changes in the general population and also increase graft failure rate in the renal transplant recipient.Objectives: To compare the serum levels of Adipocytokines and lipid profiles in renal transplant recipients with healthy individuals. Methods: In a case-control study undertaken from the beginning of 2015 to December 2016; 30 renal transplant recipients, with sta- ble conditions, whose renal transplant at least survived well over six months, were randomly selected to be the case group. Besides, 30 healthy individuals who referred to the transplantation clinic as the patients’ attendants were considered as the control group. The serum levels of IL-1, IL-6, TNF-α, Adiponectin, Visfatin, Leptin, and the Lipid profiles were measured after 12 hours of fasting and were compared between the two groups.Results: The serum levels of Adipocytokines including IL-1, IL-6, TNF-α, Visfatin, and Leptin were significantly higher in renal trans- plant recipients than in healthy individuals (P <0.001) and the serum level of adiponectin (P < 0.004) was significantly lower in the renal transplant recipients. Linear regression results indicated that in the renal transplant group, only the Visfatin had a sig- nificant negative correlation with age (Unstandardized Coefficient = -0.104, P = 0.002). There were significant positive correlations between Leptin with cholesterol (P = 0.005), triglyceride (P = 0.008), and LDL (P = 0.014) in the healthy individuals, however, these re- lationships were not found in the renal transplant recipients and only a significant negative correlation was found between Tumor necrosis factor alpha (TNF-α) and cholesterol levels (P = 0.01). Conclusions: The findings of the present study demonstrated that renal transplant recipients suffer from inflammation and ac- companying changes in levels of Adipocytokines in comparison with healthy controls

Background: Polycystic ovarian syndrome (PCOS) is a common endocrine disorder that can cause mental and psychological man- ifestations such as depression in addition to medical aspects like obesity. Objectives: The aim of this study was to evaluate the effect of cognitive-behavioral therapy on body mass index (BMI) and depression in women with PCOS. Methods: This randomized controlled trial was conducted on 74 women in Saqez-Iran, 2017. Participants were assigned into two groups of intervention and control through blocked randomization. The intervention group received cognitive-behavioral therapy in 8 sessions of 45 to 60 minutes. Beck’s depression questionnaire was completed, and body mass index (BMI) was calculated before and four weeks after the end of the intervention. ANCOVA test was used to analyze the data. Results: There was no significant difference between the two groups in terms of socio-demographic characteristics (P > 0.05). After the intervention, the mean (SD) of depression score in the intervention group was 4.5 (3.9) and in the control group 16.5 (8.6). Based on the ANCOVA test and with adjusting the baseline values, the mean depression score of the intervention group significantly was lower than the control group (adjusted mean difference: -13.8; confidence interval 95% = -10.9 to -16.7; P < 0.001). In addition, after the intervention, the mean (SD) of BMI in the intervention group was 27.3 (5.4), and in the control group it was 29.4 (5.5). The intervention group was significantly lower than the control group, based on the ANCOVA test with adjusting the baseline values (-0.6; -0.2 to -0.9; P < 0.001). Conclusions: Cognitive-behavioral therapy is effective in improving depression and decreasing BMI in women with PCOS. There- fore, it is recommended to use this therapeutic approach to improve the physical and psychological health of these women.

Background: Incisional hernia repairs are among common abdominal wall surgeries, can be primarily required or being recon- structed using a synthetic or biological material. Objectives: This study aimed at evaluating intra-abdominal adhesions and incisional site healing after the repair of the abdominal wall by fresh amniotic membrane-coated polypropylene mesh in comparison to only polypropylene mesh in an experimental rat study. Methods: The study protocol was approved by the Cumhuriyet University Institutional Ethics Committee for Animal Experiments(Sivas-Turkiye, date 24/06/2015). Sixteen pregnant female Wistar-Albino rats (mean weight, 275 g) were anesthetized on the 21st day of pregnancy, and a 1-cm area of the abdominal wall was excised. The pregnancy was terminated, emerging amniotic membranes were dissected, and eight pieces of the 1-cm2 polypropylene mesh were coated with these amniotic membranes without using any suture or adhesive. The polypropylene meshes were sutured on the abdominal wall of eight rats (control group), selected by simple random sampling. For the remaining eight rats, the same procedure was applied with the amniotic membrane-coated polypropy- lene meshes (experimental group). On the 28th postoperative day, the anterior abdominal wall was opened, and intra-abdominal adhesions were assessed macroscopically by Nair’s adhesion scoring system. Strip-shaped biopsy samples were taken from incision lines for histopathological examination.Results: The experimental group had significantly less intra-abdominal adhesions (i.e., Nair’s score of 2 to 4) compared to the con- trol group (two and six rats, respectively; P = 0.046), and had significantly lower mean score for polymorphonuclear leukocyte infil- tration (P = 0.039), hyperemia (P = 0.039), and epithelialization (P = 0.039). The score for the increase in connective tissue (P = 0.018) was significantly higher in the experimental group, and the scores for edema (P = 0.590) and macrophage infiltration (P = 0.590) were similar between the two groups. Conclusions: The use of polypropylene mesh coated with fresh amniotic membrane provides the advantage of decreasing postop- erative intra-abdominal adhesions along with less inflammation and higher epithelialization after abdominal wall repair surgery.

Background: Lactobacilli are commonly used organisms in the production of probiotics. Objectives: The present study was conducted to examine the effect of probiotics isolated from dairy products on the expression of Stx1 and Stx2 genes in verotoxigenic E. coli (VTEC). Methods: This experimental study was conducted during April and January 2016 in East Azerbaijan, Iran. At first, Hundred samples of traditional dairy products were collected. Then, using standard phenotypic and genotypic methods, the Lactobacillus casei (L. casei) and lactobacillus (L. plantarum) were studied. Subsequently, these strains were examined along with the pathogenic bacteria strain of Escherichia coli (E. coli) (O157: H7) by neighboring cultivation. After extraction of mRNA, the expression of these genes was determined using real- time PCR.Results: The results revealed that L. casei reduces the expression of Shiga toxin (Stx1 and Stx2) genes more compared to L. plantarum (P = 0.001). Moreover, it was found that both Lactobacilli reduce the expression of Stx1 genes more than Stx2. Conclusions: Probiotics could be used to prevent and control intestinal diseases caused by E. coli

Background: Oxidative stress in the pathogenesis of diabetes is of great prominence and that Carnosine is a natural antioxidant. Objectives: This study was aimed to investigate the effect of Carnosine supplementation on different oxidative stress biomarkers in patients with type 2 diabetes mellitus (T2DM). Methods: In this randomized, double-blind placebo-controlled trial, 54 patients with T2DM were employed from Tabriz Sheikhor- raees polyclinic and Imam-Reza Hospital endocrine center, and assigned to either the intervention group (n = 27) to receive two cap- sules of Carnosine 500 mg each or the control group (n = 27) to take two capsules of crystalline microcellulose for 12 weeks. Serumlevels of fasting blood sugar (FBS), malondialdehyde (MDA), protein carbonyl (PC) and erythrocytes content of catalase (CAT), and superoxide dismutase (SOD) were assessed before and after the supplementation. Results: A total of 44 patients completed the study. Anthropometric indices and energy intake did not show a significant changein both studied groups. Improved catalase level and decreased serum levels of fasting blood sugar, malondialdehyde and protein carbonyl occurred in the carnosine group compared to the placebo group after adjusting for baseline values and confounders (P < 0.05). Between-group differences were not significant for other variables at the end of the research. In the placebo group, none of the studied biomarkers were altered significantly. Conclusions: Our findings divulge the beneficial effects of carnosine supplementation in improving the antioxidant status and attenuating some of the oxidative stress biomarkers in patients with T2DM making it a useful adjunct therapy.

Background: Non-small cell lung cancer (NSCLC) is the most common type of lung Neoplasms, which accounts for about 85% of all lung cancer types. However, critical biological pathways and key genes implicated in NSCLC remain ambiguous. Objectives: The present study aimed at identifying the critical biological pathways and key genes implicated in NSCLC, and provid- ing insight into the molecular mechanism underlying NSCLC. Methods: In this case-control bioinformatics study, the researchers used four microarray data of NSCLC from public gene expres- sion omnibus (GEO) database at the national center for biotechnology information (NCBI) website. The microarray data came fromstudies of American, Spanish, and Taiwanese NSCLC patients, and in total contained 190 NSCLC tissue and 180 normal lung tissue. A standardized- microarray preprocessing and gene set enrichment analysis (GSEA) were used to analyze each microarray data and obtained significantly regulated pathways. Venn analysis was used to identify the common significantly regulated biological path- ways. Protein and protein interaction (PPI) network analysis was used to identify the key genes within common significantly reg- ulated pathways. The PPI information was retrieved from the STRING database, and Cytoscape software was used to construct and visualize the PPI network. Results: Through integrating GSEA results of four microarray data, finally, the researchers identified 22 common up-regulated and 85 common down-regulated pathways. Many genes within 107 common significantly regulated pathways were significantly en- riched within cell cycle pathway (P value of 2.58e-79) and focal adhesion pathway (P value of 2.44e-81). The PPI network showed thatup-regulated CDK1 (P value = 1.33e-18 and logFC = 1.41) and down-regulated PIK3R1 (P value = 5.09e-22 and logFC = -1.13) genes shared the most abundant edges, and were associated with NSCLC. Conclusions: This cross-sectional study showed increased concordance between gene expression profiling data. These identified pathways and genes provide some insight into the molecular mechanisms of NSCLC, and the genes may serve as candidate diagnos-tic and therapeutic targets of NSCLC.

Background: Episiotomy is one of the most common surgical procedures in obstetrics performed in the second stage of labor. Objectives: This study was conducted to compare the effects of Alpha® Ointment in comparison with Betadine® solution on epi- siotomy healing process. Methods: The present single-blind clinical trial was conducted on 128 eligible women admitted to a university affiliated hospital in Karaj, Iran, in 2015. The subjects were divided into a case group (getting an Alpha® Ointment plus a sitz bath with Betadine® solution) and a control group (getting a sitz bath with Betadine® solution). After delivery, the mothers applied 2 g of Alpha® Ointment on their episiotomy site three times a day. The REEDA scale was used to assess the wound healing process, and the intensity of pain was assessed by measuring pain in the first 24 hours as well as the third and seventh day after delivery. Results: In the first 24 hours after delivery, the two groups were not significantly different in terms of their repair score (P = 0.27), however, the mean REEDA score was 0.25 ± 0.53 on the third day and 0.203 ± 0.47 on the seventh day in the case group, while in the control group, it was 1.32 ± 1.4 and 0.92 ± 1.17, suggesting a significant difference between the groups (P < 0.001). Conclusions: Alpha® Ointment is more effective than Betadine® solution for episiotomy wound healing and pain reduction and can, therefore, be regarded as an appropriate medication for episiotomy wound healing.

Background: Insulin resistance has a pivotal role in the occurrence of impaired glucose tolerance and dyslipidemia in patients with Non-Alcoholic Fatty Liver Disease (NAFLD). There is evidence of possible beneficial effects of Alpha-Lipoic Acid (ALA) on insulin resistance and metabolic disorders. Objectives: This study aimed at examining the effects of ALA supplementation on liver enzymes, insulin sensitivity, glucose markers, and lipid profile in obese patients with NAFLD.Methods: In this double-blind placebo-controlled randomized clinical trial, 50 obese patients with NAFLD were randomly allocated to “ALA group” (received 1200 mg ALA as two capsules per day) or “Placebo group” (received placebo containing cornstarch as two capsules per day) for 12 weeks. Anthropometric measures, dietary intakes, liver enzymes as well as glucose markers and lipid profile were assessed at baseline and after 12 weeks of intervention.Results: Forty-five patients completed the study (ALA group = 23; placebo group = 22). Liver enzymes were not significantly altered by the intervention group. Alpha Lipoic Acid supplementation led to a significant attenuation in serum levels of insulin (13.4 ± 5.4 vs. 18.1 ± 8.6; P = 0.019) and triglyceride (146.9 ± 60.6 vs. 186.3 ± 54.2; P = 0.037) in comparison with the placebo group, yet did not affect other lipid profile parameters, Fasting Serum Glucose (FSG) and β-cell function index (HOMA-B) in patients with NAFLD. furthermore, quantitative insulin sensitivity check index (QUICKI) increased significantly in the ALA group compared to the placebo (0.329 ± 0.025 versus 0.317 ± 0.020; P = 0.033).Conclusions: Patients with NAFLD may benefit from ALA supplementation, at least partially through augmented insulin sensitivity and improvement of lipid profile

Background: With regards to the high potential of medicinal plants in the production of biopharmaceuticals, one can rely on the promising prospect of insulin production via plant resources. Objectives: This study was conducted with the aim of using plant extract for insulin-producing cells. Methods: This was a quasi-experimental study. In this study, critical case sampling was used. Six samples were gathered from the umbilical cord (Wharton’s jelly) at Imam hospital, after successful isolation of mesenchymal stem cells. Initially, Nigella sativa seeds extraction was performed to prepare the extract for cellular differentiation. Next, dithizone (DTZ) staining was used to evaluate insulin production and insulin level was examined by the enzyme linked immunosorbent assay (ELISA) kit. All data was analyzed with the SPSS version 16 software using independent sample t-test. Results: The mean of the amount of insulin secretion was 92.33 ± 5.13 for the intervention and 0.33 ± 0.15 for the control group. The results showed that there was a significant difference in the average insulin in the culture obtained from Nigella sativa seeds between control and intervention groups (P = 0.001). In addition, via the ELISA kit and specific dithizone staining, insulin-producing cells were proven. Conclusions: In this regard, it could be concluded that the extract of Nigella sativa seeds was capable in the induction of differenti- ation of mesenchymal stem cells derived from Wharton’s jelly to IPCs.
