Several studies have shown a number of biological properties of carotenoids, particularly beneficial impacts on cancer, metabolic, neurodegenerative, and cardiovascular diseases. However, recent evidence has shown that these compounds could prevent, delay, and ameliorate diabetic retinopathy (DR). The aim of current study was to review the therapeutic effects of carotenoids in the treatment of DR and discuss the molecular mechanisms that are behind these pharmacological activities.Methods: Six online databases (Medline/PubMed, Scopus, Web of Knowledge, Embase, ScienceDirect, and ProQuest) were searched until September 2019. The systematic review was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist.Results: A total of 25 studies were included after the final retrieval. A relationship was observed between carotenoids and management of DR. Findings also demonstrated that the underlying mechanism of beneficial effects of these compounds was antioxidant, anti-inflammatory, anti-angiogenic, and neuroprotective properties.Conclusion: Carotenoids potentially delay the initiation and prevent the progression of DR; however, ample preclinical studies are required to confirm their effect, and adequate clinical trials are needed to really understand how well these compounds influence DR among humans.Keywords: diabetic retinopathy, carotenoids, oxidative stress, inflammation, neuroprotection

Background: Today, important proteins and pathways have been identified that lead to the regulation of the white adipose tissue and converting it to brown adipose tissue, the proteins PPARγ and PRDM16 are key proteins in this setting. Diabetes is one of the major causes of obesity and complications that can interfere in the function of these two proteins. This study aimed to investigate the effect of 4 weeks High-Intensity Interval Training (HIIT) on the content of PPARγ and PRDM16 proteins in subcutaneous adipose tissue of diabetic obese male rats. Materials and Methods: In this experimental study, 16 Sprague-Dawley male rats (mean weight of 300±20 gr) were selected and after induction of diabetes by injection of STZ and nicotinamide was randomly assigned into two groups: diabetic training and diabetic control. The experimental group performed HIIT training for 4 weeks, accordance with the training program for 4 weeks, while the control group did not have any training program. Independent T-test was used to analyze the data. Results: Significant change was not observed in the content of PPARγ (P=0.16) and PRDM16 (P=0.83) proteins in HIIT training group compared to the control group. Conclusion: According to the results of this study, HIIT training has not led to significant change the content of PPARγ and PRDM16 proteins. It seems to the intensity of HIIT training be a major contributor to the result that should be taken into consideration

Background: The incidence of kidney cancer from different areas of Iran was reported. Nevertheless, there is no available systematic reviews in this regard. Therefore, the present systematic review carried out to estimate the incidence rate of kidney cancer among Iranian people. Method: This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) in September 2017. A search was concluded using Medline/ PubMed, Scopus, ScienceDirect, and Google scholar for international papers and four national databases (Scientific Information Database, MagIran, IranMedex, and IranDoc) for Persian papers. The incidence rate of kidney cancer was calculated using random effect model. Result: An aggregate of 159 papers were retrieved in the primary search of the databases. Further screening and advanced refinement of the retrieved studies produced 15 studies totally. The age-standardized rate (ASR) of kidney cancer was 1.94, 95% CI (1.62-2.55) and 1.36, 95 % CI (1.09-1.62) in males and females, respectively. Conclusion: In comparison to other parts of the world, the incidence of kidney cancer was lower in Iran. Afterwards, further studies are necessary to outline the exact incidence rate and the trend of kidney cancer in Iran.

Background: Deferoxamine is a potent iron chelator that could remove iron from the virus, and severe acute respiratory syndrome coronavirus 2 requires iron to replication. Also, deferoxamine has antioxidant and cytokine-modulating effects. Therefore, we evaluated the efficacy and safety of deferoxamine in patients with moderate coronavirus disease 2019 (COVID-19)., Methods: In this randomized controlled trial, patients with moderate COVID-19 were randomly assigned in a 1:1 ratio to the deferoxamine group (received a solution of 500 mg deferoxamine divided into 4 doses a day through a nebulizer for 7 days) and the control group. The main outcomes were viral clearance, oxygen saturation (SPO2), body temperature, and respiratory rate (RR). Intensive care unit admission, hospital length of stay, and hospital mortality were also assessed., Results: A total of 62 patients, with 30 in the deferoxamine group and 32 in the control group, were randomly assigned. There was no statistically significant improvement in viral clearance after the intervention ended in the deferoxamine group (36.7%) compared to the control group (34.4%). The results showed there was no significant difference between the analyzed groups in terms of SPO2, body temperature, RR, and the number of patients with a worse prognosis (SPO2 < 96%, temperature ≥ 37.5 °C, or RR ≥ 16/min) at the end of the study. There were no significant differences seen between the groups in terms of intensive care unit admission, hospital length of stay, hospital mortality, and the occurrence of adverse medication events during the follow-up period., Conclusion: Deferoxamine had no significant impact on improving moderately ill patients with COVID-19. However, it was well-tolerated in the patients, and this intervention demonstrated a safe profile of adverse events., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Background: Ginger, a potent antiviral, anti-inflammatory, and antioxidant remedy, is a potential therapeutic option for COVID-19. However, there was not enough clinical evidence about ginger and COVID-19. We evaluated the efficacy and safety of ginger on clinical and paraclinical features in outpatients with COVID-19., Methods: In this randomized controlled trial, the outpatients with confirmed COVID-19 were randomly assigned in a 1:1 ratio to receive ginger (1000 mg 3 times a day for 7 days) or placebo. The primary outcome was viral clearance after the end of the intervention. Oxygen saturation (SPO2), body temperature, respiratory rate (RR), hospital admission, and the incidence of adverse events were also assessed., Results: A total of 84 patients (42 in the ginger and 42 in the control groups) were randomized. The viral clearance was not statistically improved in the ginger group (41.6%) compared to the placebo group (42.8%). The findings indicated that SPO2, body temperature, and RR had no significant difference between the groups at the end of the intervention. The imaging finding indicated pulmonary infiltrate significantly reduced on the 7th day of the intervention in the ginger group. The percentage of patients with SPO2 <96% in the ginger group decreased over the study compared to the placebo group. Moreover, the need for hospital admission and the incidence of adverse drug events were not different between the groups over the follow-up period., Conclusions: Ginger had no significant impact on the clinical and paraclinical parameters of patients. However, this intervention demonstrated a safe profile of adverse events and reduced pulmonary infiltrate., Trial Registration: The trial was registered as IRCT20200506047323N1., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Coronavirus disease 2019 (COVID-19) vaccines are the most effective tools in managing the pandemic. However, the concern about these vaccines is the occurrence of unwanted adverse events (AEs). This study aimed to evaluate the short-term AEs of COVID-19 vaccines (Sputnik V, Astrazenka, and Sinopharm). A cross-sectional study using an online questionnaire was conducted among 321 vaccinated individuals. Demographic information, history of drug use, prior infection with COVID-19, the type of vaccine, vaccination stage, local injection site complication, systemic complication, and allergic reactions were collected and evaluated. Local complications, including pain and swelling at the injection site, and systemic complications, including fever, fatigue, lethargy, lymphadenopathy, and diarrhea, were reported after the injection of the AstraZeneca vaccine was more than the other 2 vaccines; The prevalence of fatigue and lethargy was higher than other systemic complications. The least reported complication was due to lymphadenopathy. The Sinopharm vaccine showed a lower prevalence of AEs than the other 2. The rare AEs, such as facial paralysis, nasal bleeding, and urticarial, were further reported after injection of the AstraZeneca vaccine. In general, the severity of systemic complications after the second dose of the vaccine was also higher than the first dose. All 3 vaccines were safe and tolerable. The most commonly reported AEs were injection site pain (local) and fatigue and lethargy (systemic). These expected AEs occurred shortly after vaccination and indicated an early immune response after vaccination., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Licorice extract (glycyrrhizin), a potent antiviral, anti-inflammatory, and antioxidant remedy, is a potential therapeutic option for COVID-19. We evaluated the efficacy and safety of licorice in patients with moderate COVID-19. In this study, 60 patients with confirmed COVID-19 were randomly assigned in a 1:1 ratio to receive licorice (at a dose of 760 mg three times a day for seven days) or control groups. The primary outcomes were S P O 2 , body temperature, and respiratory rate (RR) after the end of the intervention. The findings indicated that S P O 2 , body temperature, and RR had no significant difference between the groups at the end of the intervention. However, CRP and ALT improved in the licorice group toward the baseline. The number of patients with worse prognoses, LOS, mortality, and the incidence of adverse events were not different between the groups at the end of the study. Licorice had no beneficial effect on the clinical symptoms of COVID-19. Moreover, this intervention demonstrated a safe profile of adverse events. The confirmation of the results of this preparatory trial requires more detailed multiple-center trials with a larger sample size., (© 2023.

Patients with COVID-19 have shown melatonin deficiency. We evaluated the efficacy and safety of administration oral melatonin in patients with COVID-19-induced pneumonia. Patients were randomly assigned in a 1:1 ratio to receive melatonin plus standard treatment or standard treatment alone. The primary outcomes were mortality rate and requirement of IMV. The clinical status of patients was recorded at baseline and every day over hospitalization based on seven-category ordinal scale from 1 (discharged) to 7 (death). A total of 226 patients (109 in the melatonin group and 117 in the control group) were enrolled (median age; in melatonin group: 54.60 ± 11.51, in control group: 54.69 ± 13.40). The mortality rate was 67% in the melatonin group and 94% in the control group (OR; 7.75, 95% CI, 3.27-18.35, P < 0.001). The rate of IMV requirement was 51.4% in the melatonin group and 70.9% in the control group, for an OR of 2.31 (95% CI, 1.34-4.00, P < 0.001). The median number of days to hospital discharge was 15 days (13-17) in the melatonin group and 21 days (14-24) in the control group (OR; 5.00, 95% CI, 0.15-9.84, P = 0.026). Time to clinical status improvement by ≥ 2 on the ordinal scale in was 12 days (9-13) in the melatonin group and 16 days (10-19) in the control group (OR; 3.92, 95% CI, 1.69-6.14, P = 0.038). Melatonin significantly improved clinical status with a safe profile in patients with severe COVID-19 pneumonia., (© 2022. The Author(s), under exclusive licence to Springer Nature Switzerland AG.)

The incidence of microbial resistance is growing, and new rescue regimens are needed to treat Helicobacter pylori ( H. pylori ) infection. This study aimed to evaluate levofloxacin-based quadruple therapies' efficacy, safety, and tolerability in eradicating H. pylori . In a randomized, double-blind clinical trial, 220 patients with dyspepsia and H. pylori infection were randomly assigned to receive either bismuth subcitrate 240 mg, pantoprazole 20 mg, amoxicillin 1000 mg twice a day, and levofloxacin 500 mg daily for seven days (BPAL-7) or ten days (BPAL-10). The eradication of H. pylori was evaluated two months after the end of treatment, and adverse drug reactions (ADRs) were assessed during the intervention. According to intention-to-treat and per-protocol, the eradication rate was significantly lower in the BPAL-7 regimen at 49.1% (95% CI: 39.3-57.8) and 47.6% (95% CI: 39.7-58.4), respectively, compared to the BPAL-10 regimen at 62.7% (95% CI: 53.6-72.8) and 62.4% (95% CI: 55.1-72.8), respectively. The ADR incidence was not statistically significant between the groups of BPAL-7 (33.6%) and BPAL-10 (36.7%). Although the ADRs were negligible in both groups, these regimens could not be an ideal alternative therapy for H. pylori because of their low eradication rates compared to standard regimens. Trial Registration . The study was reviewed and approved by the Iranian Registry of Clinical Trials (IRCT201406141155N19)., Competing Interests: The authors declare that they have no conflicts of interest in this work., (Copyright © 2022 Fariborz Mansour-Ghanaei et al.)

Favipiravir (FVP), lopinavir/ritonavir (LPV/RTV), and interferon-beta (INF-beta) are considered as potential treatments for COVID-19. We examined the efficacy and safety of FVP and INF-beta compared to LPV/RTV and INF-beta combinations for the treatment of SARS-CoV-2. It was a single-center randomized clinical trial. Eligible patients were randomized to receive FVP plus INF-beta versus LPV/RTV plus INF-beta. The primary endpoint was the viral clearance after seven days of randomization. ICU admission, length of stay (LOS) in hospital, in-hospital mortality, and the incidence of adverse events were also measured. This trial was registered on the Iranian Registry of Clinical Trials (IRCT20200506047323N3). Patients were randomly allocated to the FVP (n = 33) and LPV/RTV (n = 33) groups. The viral clearance on Day seven was not significantly different between the FVP (31.1%) and the LPV/RTV groups (16.1%). The rate of ICU admission and likewise the in-hospital mortality in the FVP group (12.5% and 6.3%, respectively) were similar to the LPV/RTV groups (19.4% and 19.4%, respectively). The median LOS in the hospital was also not different (6.8 days [interquartile range; IQR = 5.0-11.0] in the FVP and (8.0 days [IQR = 5.5-12.5]) in LPV/RTV groups (p = 0.140). Adverse events were observed in 25.0% of FVP and 32.3% of LPV/RTV groups. The combination therapy with FVP did not exert a higher efficacy compared to the combination regimen of LPV/RTV. However, both treatment regimens demonstrated a mild profile of adverse events., (© 2022 Wiley Periodicals LLC.)

Background: At present, nonalcoholic fatty liver disease (NAFLD) does not have an approved pharmacologic therapy. The present study investigated the protective effects and possible mechanisms of milk thistle ( Silybum marianum L.) and artichoke ( Cynara scolymus L.) in treating NAFLD in type 2 diabetic rats., Methods: The NAFLD was established in rats after four weeks of type 2 diabetes induction. The animals were treated with pharmaceutical preparations of milk thistle (Livergol®) and artichoke (Atheromod-B®) extracts for eight weeks. After the end of the intervention, oral glucose tolerance, the serum parameters of oxidative stress, liver functional tests, and lipid profiles were evaluated. Histopathological changes were assessed by hematoxylin and eosin staining., Results: Treatment with preparations of milk thistle and artichoke nonsignificantly improved glucose tolerance in diabetic rats. Both preparations significantly improved serum superoxide dismutase activity and the level of malondialdehyde. Although treatment with milk thistle reduced serum activity of aspartate aminotransferase and serum levels of triglyceride (TG), total cholesterol, and low-density lipoprotein-cholesterol, artichoke extracts only attenuated the serum level of TG. Milk thistle also effectively protected the liver from histological changes., Conclusions: Milk thistle could be a promising pharmacological option for the treatment of NAFLD. Nonetheless, long-term randomized clinical trials are necessary to confirm the observed results., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2022 Aida Doostkam et al.)

In COVID-19 patients, cytokine storm due to excessive immune responses can cause severe complications. In this study, we investigated the effect of curcumin nanomicelles on clinical outcome and cellular immune responses subtypes changes in COVID-19 patients. A randomized, triple-blinded, placebo-controlled study was done. Forty COVID-19 patients were included into two groups of nano-curcumin and placebo. The nano-curcumin group received 40 mg of nano-curcumin capsule, four times per day for 2 weeks. Clinical signs and gene expression of TBX21, GATA3, RORC and FOXP3 genes and IFN-γ, IL-4, IL-17 and TGF-β cytokines serum levels were measured at time points of 0, 7 and 14 days. Serum levels of IFN-γ (p = .52) and IL-17 (p = .11) decreased, while IL-4 (p = .12) and TGF-β (p = .14) increased in the nano-curcumin group compared with placebo on day 14. Moreover, gene expressions of TBX21 (p = .02) and FOXP3 (p = .005) genes were significantly decreased and increased between nano-curcumin and placebo groups on day 7, respectively. It can be concluded that administration of nano-curcumin in inflammatory phase of COVID-19 can accelerate recovering of the acute inflammatory phase by modulating inflammatory immune responses. Therefore, it is suggested that this supplement in inflammatory diseases, including COVID-19, can be effective in controlling the inflammatory responses., (© 2021 John Wiley & Sons Ltd.)

The main protease of SARS-CoV-2 is one of the key targets to develop and design antiviral drugs. There is no general agreement on the use of non-steroidal anti-inflammatory drugs (NSAIDs) in COVID-19. In this study, we investigated NSAIDs as potential inhibitors for chymotrypsin-like protease (3CLpro) and the main protease of the SARS-CoV-2 to find out the best candidates, which can act as potent inhibitors against the main protease. We also predicted the effect of NSAIDs on the arachidonic pathway and evaluated the hepatotoxicity of the compounds using systems biology techniques. Molecular docking was conducted via AutoDock Vina to estimate the interactions and binding affinities between selected NSAIDs and the main protease. Molecular docking results showed the presence of 10 NSAIDs based on lower binding energy (kcal/mol) toward the 3CLpro inhibition site compared to the co-crystal native ligand Inhibitor N3 (-6.6 kcal/mol). To validate the docking results, molecular dynamic (MD) simulations on the top inhibitor, Talniflumate, were performed. To obtain differentially-expressed genes under the 27 NSAIDs perturbations, we utilized the L1000 final Z-scores from the NCBI GEO repository (GSE92742). The obtained dataset included gene expression profiling signatures for 27 NSAIDs. The hepatotoxicity of NSAIDs was studied by systems biology modeling of Disturbed Metabolic Pathways. This study highlights the new application of NSAIDs as anti-viral drugs used against COVID-19. NSAIDs may also attenuate the cytokine storm through the downregulation of inflammatory mediators in the arachidonic acid pathway., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

Background: Diabetic nephropathy (DN) is the major complication of diabetes mellitus, and leading cause of end-stage renal disease. The underlying molecular mechanism of DN is not yet completely clear. The aim of this study was to analyze a DN microarray dataset using weighted gene co-expression network analysis (WGCNA) algorithm for better understanding of DN pathogenesis and exploring key genes in the disease progression., Methods: The identified differentially expressed genes (DEGs) in DN dataset GSE47183 were introduced to WGCNA algorithm to construct co-expression modules. STRING database was used for construction of Protein-protein interaction (PPI) networks of the genes in all modules and the hub genes were identified considering both the degree centrality in the PPI networks and the ranked lists of weighted networks. Gene ontology and Reactome pathway enrichment analyses were performed on each module to understand their involvement in the biological processes and pathways. Following validation of the hub genes in another DN dataset (GSE96804), their up-stream regulators, including microRNAs and transcription factors were predicted and a regulatory network comprising of all these molecules was constructed., Results: After normalization and analysis of the dataset, 2475 significant DEGs were identified and clustered into six different co-expression modules by WGCNA algorithm. Then, DEGs of each module were subjected to functional enrichment analyses and PPI network constructions. Metabolic processes, cell cycle control, and apoptosis were among the top enriched terms. In the next step, 23 hub genes were identified among the modules in genes and five of them, including FN1, SLC2A2, FABP1, EHHADH and PIPOX were validated in another DN dataset. In the regulatory network, FN1 was the most affected hub gene and mir-27a and REAL were recognized as two main upstream-regulators of the hub genes., Conclusions: The identified hub genes from the hearts of co-expression modules could widen our understanding of the DN development and might be of targets of future investigations, exploring their therapeutic potentials for treatment of this complicated disease.

The novel coronavirus outbreak began in late December 2019 and rapidly spread worldwide, critically impacting public health systems. A number of already approved and marketed drugs are being tested for repurposing, including Favipiravir. We aim to investigate the efficacy and safety of Favipiravir in treatment of COVID-19 patients through a systematic review and meta-analysis. This systematic review and meta-analysis were reported in accordance with the PRISMA statement. We registered the protocol in the PROSPERO (CRD42020180032). All clinical trials which addressed the safety and efficacy of Favipiravir in comparison to other control groups for treatment of patients with confirmed infection with SARS-CoV2 were included. We searched electronic databases including LitCovid/PubMed, Scopus, Web of Sciences, Cochrane, and Scientific Information Database up to 31 December 2020. We assessed the risk of bias of the included studies using Cochrane Collaboration criteria. All analyses were performed using the Comprehensive Meta-Analysis software version 2, and the risk ratio index was calculated. Egger and Begg test was used for assessing publication bias. Nine studies were included in our meta-analysis. The results of the meta-analysis revealed a significant clinical improvement in the Favipiravir group versus the control group during seven days after hospitalization (RR = 1.24, 95% CI: 1.09-1.41; P = 0.001). Viral clearance was more in 14 days after hospitalization in Favipiravir group than control group, but this finding marginally not significant (RR = 1.11, 95% CI: 0.98-1.25; P = 0.094). Requiring supplemental oxygen therapy in the Favipiravir group was 7% less than the control group, (RR = 0.93, 95% CI: 0.67-1.28; P = 0.664). Transferred to ICU and adverse events were not statistically different between two groups. The mortality rate in the Favipiravir group was approximately 30% less than the control group, but this finding not statistically significant. Favipiravir possibly exerted no significant beneficial effect in the term of mortality in the general group of patients with mild to moderate COVID-19. We should consider that perhaps the use of antiviral once the patient has symptoms is too late and this would explain their low efficacy in the clinical setting.

Background: Occupational contact with blood and body fluids poses a significant risk to healthcare workers. The aim of this systematic review is to investigate the epidemiology and risk factors affecting needlestick injuries (NSI) in healthcare personnel in Iran., Methods: In March 2020, researchers studied six international databases such as Medline/PubMed, ProQuest, ISI/WOS, Scopus, Embase, and Google Scholar for English papers and two Iranian databases (MagIran and SID) for Persian papers. Joanna Briggs Institute (JBI) Critical Appraisal Checklist was used to assess quality of studies. The method of reporting was based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement., Results: A total of 43 articles were included in the analysis. Results showed that females (OR = 1.30, 95 % CI 1.06-1.58, P value = 0.009), younger age (OR = 2.75, 95 % CI 2.27-3.33, P value < 0.001, rotated shift workers (OR = 2.16, 95 % CI 1.47-3.15, P value < 0.001), not attending training courses (OR = 1.30, 95 % CI 1.07-1.56, P value = 0.006), working in the surgery ward (OR = 1.83, 95 % CI 1.33-2.50, P value < 0.001), less work experience (OR = 1.43, 95 % CI 1.04-1.95, P value = 0.025) apposed a greater risk factors for NSI among healthcare workers., Conclusion: Based on the results of this review, factors such as young age, less work experience, work shift, and female gender are considered as strong risk factors for NSI injury in Iran. Preventive measures including education programs can reduce the burden of NSI among healthcare personnel.

Objective: Hepatitis B (HB) and C (HC) are two severe viral infectious diseases with a deleterious impact on global health. This study aimed to evaluate the prevalence of HB and HC in the Prospective Epidemiological Research Studies of the Iranian Adults (PERSIAN) Guilan Cohort Study using immunological and molecular methods., Results: The blood samples were obtained from 10,520 enrolled participants. Complete biochemical and hematological tests, as well as urine analysis, were assessed. The presence of HBsAg, anti-HBs, anti-HBc, and anti-HCV antibodies for all participant and HBeAg and anti-HBe antibodies for HB-positive patients were evaluated. Moreover, HB genomic DNA and HC genomic RNA were extracted from serum samples of HB-positive patients. The real-time PCR assay was employed to quantify the gene copies of hepatitis B and C viruses. HC genotyping was also performed. The prevalence of HB and HC was 0.24% (95% CI 0.16-0.35) and 0.11% (95% CI 0.06-0.19), respectively. Rural participants were significantly more HB-positive than the urban people (P = 0.045), while males were significantly more HC-positive than the females (P = 0.013). The prevalence of HB and HC in this area were lower than those of other geographical locations of Iran, which may be due to different lifestyles or other unknown reasons.

Background: Burn wound infection and sepsis are serious medical conditions requiring prompt intervention. Plants are a good natural source for the development of novel, safe, and cost-effective antibacterial agents. The objective of the present study was to assess the antibacterial potential of aqueous, chloroform, and methanol extracts of the Prunus scoparia ( P. scoparia ) root against the most common burn wound pathogens., Methods: The present experimental study was conducted at Shiraz University of Medical Sciences (Shiraz, Iran) during 2018-2019. The antibacterial activity of the total plant extract was assayed using the broth microdilution method. Fractionation was performed using a separation funnel and solvents with different polarities. Broth microdilution and agar well diffusion assays were performed to determine the antibacterial potential of the obtained fractions. Quantitative and qualitative phytochemical analyses were performed to confirm the presence of secondary metabolites in both the total extract and the fractions., Results: Methanolic extract of P. scoparia root exhibited antibacterial activity against all tested bacterial strains, especially against Methicillin-resistant Staphylococcus aureus (MRSA) isolates. This extract, compared to the aqueous and chloroformic extracts, exhibited the presence of active antibacterial compounds. The quantitative and qualitative results of phytochemical screening showed that phenols and flavonoids were the main antibacterial compounds in the methanolic extract of the plant., Conclusion: For the first time, we demonstrated the antibacterial activity of the P. scoparia root against MRSA isolates and other common burn wound pathogens., (Copyright: © Iranian Journal of Medical Sciences.)

Background and Aims: Pistachio nuts have been considered to improve dysglycemia. However, there are controversial results. This systematic review and meta-analysis carried out to evaluate the effects of pistachio nuts on glycemic control and insulin sensitivity in patients with type 2 diabetes mellitus (T2DM), prediabetes, and metabolic syndrome., Methods: Medline/PubMed, ProQuest, Web of Knowledge, Scopus, Cochrane library, and ScienceDirect were systematically searched to find randomized controlled trials (RCTs). Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist was used to conduct the study., Results: Six RCTs were included in the review. Treatment with pistachio nuts exerted a significant reduction in fasting blood glucose (FBG) level (OR = 1.7, 95% CI; 1.2-2.4, P = 0.002, I 2  = 0.0%, P = 0.731) and homeostasis model assessment of insulin resistance (HOMA-IR) index (OR = 1.5, 95% CI; 1.0-2.4, P = 0.043, I 2  = 0.0%, P = 0.617), but no significant improvement was observed in regard to hemoglobin A1c (HbA1c) level (OR = 1.4, 95% CI; 0.9-2.1 P = 0.089, I 2  = 0.0%, P = 0.957) and fasting plasma insulin (FPI) level (OR = 1.3, 95% CI; 0.9-1.9, P = 0.133, I 2  = 0.0%, P = 0.776)., Conclusions: Pistachio nuts might cause a significant reduction in FBG and HOMA-IR, although HbA1c and FPI might not significantly improve in patients suffering from or at risk of T2DM., Competing Interests: Declaration of competing interest No potential conflict of interest relevant to this article was reported., (Copyright © 2020 Diabetes India.

Background: Previous studies of diabetes in Eastern Mediterranean Region (EMRO) did not assess the prevalence of either unknown diabetes or prediabetes. We conducted a systematic review and meta-analysis to estimate the prevalence of undiagnosed type 2 diabetes and prediabetes as well as variations by region in EMRO, using the relevant publications since 2000., Methods: We carried out a comprehensive electronic search on electronic databases from January 1, 2000 to March 1, 2018. We selected cross-sectional and cohort studies reporting the prevalence of undiagnosed type 2 diabetes, prediabetes, or both. Two independent reviewers initially screened the eligible articles; then, synthesized the target data from full papers. Random- or fixed-effect models, subgroup analysis on Human Development Index (HDI), and publication year and sensitivity analysis to minimize the plausible effect of outliers were used., Results: Amongst 849 identified citations, 55 articles were entered into meta-analysis, involving 567,025 individuals. The forest plots estimated 5.46% (confidence intervals [CI]: 4.77-6.14) undiagnosed diabetic and 12.19% (CI: 10.13-14.24) prediabetics in EMRO. Low HDI countries and high HDI countries had the highest (7.25%; CI: 4.59-9.92) and the lowest (3.98%; CI: 3.11-4.85) undiagnosed diabetes prevalence, respectively. Very high HDI countries and low HDI countries had the highest (13.50%; CI: 8.43-18.57) and the lowest (7.45%; 1.20-13.71) prediabetes prevalence, respectively. In addition, meta-regression analysis showed a statistically significant association between publication year and prevalence of prediabetes (Reg Coef = 0.059, P = 0.014). But such finding was not observed for undiagnosed diabetes and publication year (Reg Coef = 0.034, P = 0.124), prediabetes and HDI (Reg Coef = 0.128, P = 0.31) and undiagnosed diabetes and HDI (Reg Coef = - 0.04, P = 0.96)., Conclusion: The prevalence of undiagnosed diabetes and prediabetes was high and increasing. The notion of universal health coverage is a priority; that is the integration of the primary, secondary and tertiary health levels, as well as employing the available action plans. Therefore, future studies, using identical screening tool and diagnostic criteria, are warranted to make an accurate picture of diabetes in EMRO., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2019 Elsevier B.V.

Background: Prostate cancer is one of the most common health issues among men, especially older men. In recent years, incidences of prostate cancer is increasing., Objective: The aim of this study was to provide a comprehensive estimate of the survival of prostate cancer in Asian countries., Methods: We searched five international databases including Medline/PubMed, Scopus, Embase, Web of Knowledge and ProQuest until June 1, 2018. The Newcastle-Ottawa Quality Assessment was used to evaluate the quality of selected papers. The review protocol was registered in PROSPERO (CRD42019117044)., Results: A total of 714 titles were retrieved. Thirty-seven studies met the inclusion criteria. Based on the random-effect model one-year, five-year and ten-year survival rate of prostate cancer were 81% (95% CI 77.8-84.2), 61.9% (95% CI 59.5-64.3) and 36.2% (95% CI 9.2-63.2) respectively. Survival rates based on HDI level for five-year were 30.07, 43.43 and 70.84 percent for medium, high and very high levels, respectively., Conclusion: According to the results of our study, the prostate cancer survival rate in Asian countries is relatively lower than in Europe and North America., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2020 The Author(s).)

Background: Liposomes constitute a promising drug delivery vehicle, and are believed to improve drugs' effectiveness. This study was aimed to compare antihypertensive and vascular modifying activities of liposomal and non-liposomal forms of ascorbic acid., Methods: Forty-nine male Sprague-Dawley rats were randomly divided into seven groups (n=7): A sham vehicle-receiving (Sham-veh), hypertensive (HTN), vehicle-receiving hypertensive (HTN-Veh), two liposomal Ascorbic acid-treated hypertensive at 50 or 100 mg/kg/day (LVC-50 and LVC-100), and two non-liposomal Ascorbic acid-treated hypertensive at 50 or 100 mg/kg/day (VC-50 and VC-100). Systolic blood pressure (SBP) and heart rate (HR) were measured weekly; after 4 weeks, dose-responses to phenylephrine (PE) in the absence and presence of nitro-L-arginine methyl ester (L-NAME), acetylcholine (Ach), and sodium nitroprusside (SNP) were obtained on aortic rings. Data were analyzed with one-way ANOVA and Duncan's multiple range test at a P value of <0.05 using Sigmastat statistical software., Results: Compared to the non-liposomal form, the liposomal one was associated with more prominent effects on the final SBP. Both forms of Ascorbic acid decreased SBP dose-dependently. The basal and stimulated release of Nitric Oxide (NO) was significantly recovered by both forms of Ascorbic acid. The PE maximal responses were not significantly different between the liposomal and non-liposomal groups (P=0.08). Although the Emax of Ach-relaxation response was not different in two preparation forms, Ach-relaxation response induced a lower concentration of the liposomal form of Ascorbic acid (P=0.03., Conclusion: The liposomal Ascorbic acid exhibited relaxation activity in significantly lower concentrations. The observed effects were partly mediated by the increased basal release of NO., (Copyright: © Shiraz University of Medical Sciences.)

The purpose of this study was to examine the neuroprotective effects of caffeic acid hexyl (CAF6) and dodecyl (CAF12) amide derivatives on the early stage of retinopathy in streptozotocin-induced diabetic rats. Animals were divided in five groups (n=8/group); one group consisted of non-diabetic rats as control, while the other four were diabetic animals either non-treated or treated with CAF6, CAF12 or resveratrol intravitreally for four weeks. Retinal superoxide dismutase (SOD) activity and 8-iso-prostaglandin F 2α (iPF 2α ) levels were evaluated by an ELISA assay. Phosphorylation of ERK1/2 and AKT was determined by immunoblotting in retinal homogenates. Retinal morphology was also examined using light microscopy. Treatment with CAF6 and CAF12 increased retinal SOD activity, while it decreased iPF 2α levels in diabetic rats. Phosphorylation of ERK1/2 was increased, while AKT phosphorylation was decreased in diabetic rats compared to normal control and these alterations were significantly reversed in diabetic rats treated with CAF6 and CAF12. Furthermore, thickness of the whole retinal layer, outer nuclear layer, and ganglion cell count were decreased in diabetic rats compared to control and CAF6 and CAF12 treatments prevented these changes. CAF6 and CAF12 seem to be effective agents for treatment of diabetic retinopathy via attenuation of retinal oxidative stress and improvement of neuronal survival signaling., (© 2019 Wiley-VHCA AG, Zurich, Switzerland.)

The optimal pharmacological regimen for eradication of Helicobacter pylori ( H. pylori ) has been investigated for many years. This study aimed to evaluate the efficacy and tolerability of bismuth-based quadruple therapy (B-QT) and a modified sequential therapy (ST) regimens in eradication of H. pylori . A randomized, double-blind trial was conducted on 344 patients. Patients with H. pylori infection and without a history of previous treatment were randomized to receive 14-day B-QT (bismuth subcitrate 240 mg, pantoprazole 40 mg, amoxicillin 1000 mg, and clarithromycin 500 mg twice daily) or 14-day ST (bismuth subcitrate 240 mg, pantoprazole 40 mg, amoxicillin 1000 mg, and metronidazole 500 mg twice a day for seven days followed by bismuth subcitrate 240 mg, pantoprazole 40 mg, amoxicillin 1000 mg, and furazolidone 100 mg twice a day for additional seven days). Drug adverse effects were assessed during the study. H. pylori eradication was determined eight weeks after the end of treatment using 14 C-urea breath test. Based on per-protocol and intention-to-treat, the eradication rate was significantly higher (p<0.05) in the B-QT regimen 91.9 % (95 % CI; 88.1-94.0) and 90.2 % (95 % CI; 86.3-92.9), respectively compared to the ST regimen 80.8 % (95 % CI; 76.6-84.9) and 78.1 % (95 % CI; 73.7-82.4), respectively. The severity of vomiting and loss of appetite were significantly higher in ST regimen (p<0.05). The B-QT regimen was more effective and safer than the ST regimen. Conclusively, it is suggested to assess the efficacy and safety of this regimen in longer studies, larger population, and in other communities., (Copyright © 2019 Mansour-Ghanaei et al.)

Purpose: Hepatocellular carcinoma or liver cancer (LC) is one of most important cancer around the world. There are several reports about LC incidence from various Iranian locations with conflicting results. The present study aimed to accomplish a systematic review to estimate the accurate incidence rate of LC among Iranian people., Methods: This systematic review was performed based on the preferred reporting items for systematic reviews and meta-analyses (PRISMA) checklist in 2018. A literature search was conducted using international databases (Medline/PubMed, Scopus, ScienceDirect, and Google Scholar) for English papers and national databases (Scientific Information Database, MagIran, IranMedex, and IranDoc) for Persian papers which estimated incidence rate of LC in any geographical area of Iran. The incidence rate of LC was calculated using random effect model., Results: Of 171 papers in the primary searches, 15 studies were included by advanced screening and refinement. The age-standardized rate (ASR) of LC was 1.66 (95% CI 1.49-1.83) for males and 1.25 (95% CI 1.12-1.38) for females., Conclusions: The incidence rate of LC in Iran was lower in comparison to other countries. Afterwards, more studies are necessary to outline the accurate incidence rate and the trend of LC among Iranian population.

Background and Aim: Gastrointestinal (GI) symptoms are common in patients with diabetes mellitus (DM), which involved in high cost of health care and low quality of life. The aim of this study to investigate the prevalence of GI symptoms in diabetic patients referred to the Gastrointestinal and Liver Diseases Research Center (GLDRC), Guilan University of Medical Sciences (Rasht, Iran) using a validated questionnaire., Methods: In this descriptive, cross-sectional study, 255 diabetic patients and 255 non-diabetic subjects were recruited. Participants were randomly selected. The questionnaire recorded GI symptoms among the study population., Results: GI symptoms were reported in 91.4% of diabetic patients, and 42.1% of them were male. The common GI symptoms in diabetic patients were flatulence (33.0%), followed by retrosternal pain (14.9%), belching (13.7%), postprandial fullness (12.5%), and constipation (11.4%). Retrosternal pain, constipation, flatulence, loss of appetite, and abdominal distention were more prevalent in diabetic women than men., Conclusions: DM is associated with high prevalence rate of upper and lower GI symptoms. This effect may be linked to gender and poor glycemic control in diabetic patients, but not to type and duration of diabetes., (Copyright © 2019 Diabetes India. Published by Elsevier Ltd.

The design, synthesis, antinociceptive and β-adrenoceptor blocking activities of several eugenyloxy propanol azole derivatives have been described. In this synthesis, the reaction of eugenol with epichlorohydrin provided adducts 3 and 4 which were N-alkylated by diverse azoles to obtain the eugenyloxy propanol azole analogues in good yields. Adducts 3 and 4 were also reacted with azide ion to obtain the corresponding azide 6. The 'Click' Huisgen cycloaddition reaction of 6 with diverse alkynes afforded the title compounds in good yields. The synthesized eugenyloxy propanol azole derivatives were in vivo studied for the acute antinociception on male Spargue Dawley rats using tail-flick test. Compounds 5f, 5g, 7b and 11a exhibited potent analgesic properties in comparison with eugenol as a standard drug. In addition, all compounds were ex vivo tested for β-adrenoceptor blocking properties on isolated left atrium of male rats which exhibited partial antagonist or agonist behaviour compared to the standard drugs. The molecular docking study on the binding site of transient receptor potential vanilloid subtype 1 (TRPV1) has indicated that like capsaicin, eugenyloxy propanol azole analogues exhibited the strong affinity to bind at site of TPRV1 in a "tail-up, head-down" conformation and the presence of triazolyl moieties has played undeniable role in durable binding of these ligands to TRPV1. The in silico pharmacokinetic profile, drug likeness and toxicity predictions carried out for all compounds determined that 5g can be considered as potential antinociceptive drug candidate for future research.

Background: Prostate cancer is one of the most common cancers among men. There are various estimates of prostate cancer incidence from different geographical areas in Iran. In addition, no systematic reviews are available regarding the incidence rate of prostate cancer in Iran. Therefore, the present systematic review aimed to address this epidemiological gap., Method: This systematic review was performed based on the preferred reporting items for systematic reviews and meta-analyses in July 2017. In doing so, the researchers searched Medline/PubMed, Scopus, Embase, ScienceDirect, and Google Scholar for international articles and four Iranian databases (Scientific Information Database, MagIran, IranMedex, and IranDoc) for Persian articles., Result: A total of 274 titles were retrieved in the initial search of the databases. Further refinement and screening of the retrieved studies produced a total of 21 studies. Based on the random-effect model, the age-standardized rate of prostate cancer was 9.11 and 95% confidence interval was 8.19-10.04. Besides, the results of Cochran's test indicated the heterogeneity of the studies (Q = 1457.8, df = 46.0, I 2  = 96.8%, P  < 0.001)., Conclusion: The incidence of prostate cancer was lower in Iran than in the other parts of the world. Yet, establishing cancer registries covering a broader perspective of the population and conducting further studies are required to map out the exact incidence rate and trend of prostate cancer in Iran.
