The association between psoriasis and diabetes mellitus: A systematic review and meta-analysis

Background: Psoriasis is an immune-mediated chronic inflammatory skin disease with unknown etiology. Current findings demonstrate that psoriatic patients are at higher risk of other systemic disorders such as diabetes mellitus. The present study was conducted to evaluate the association between psoriasis and diabetes mellitus. Method: The current study was conducted based on preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. Using MeSH keywords we searched online databases of PubMed, Scopus, Web of Science, Science Direct, Embase, CINAHL, Cochrane Library, EBSCO and Google scholar search engine and the reference list of the retrieved articles until June 2018. Heterogeneity among studies was assessed using Cochran's Q test and I 2 index and the random effects model was used to estimate Odds Ratio (OR) and 95 confidence interval (CI). Data were analyzed using Comprehensive Meta-Analysis (CMA) software version 2. Results: Analysis of 38 eligible studies involving 922870 cases and 12808071 controls suggested the estimated OR to be 1.69 (95 Confidence Interval CI: 1.51–1.89; P < 0.001). Subgroup analysis was conducted based on study design and country of study and was significant (test for subgroup differences: P = 0.025 and P < 0.001, respectively). Conclusions: Our study indicated the significant association between psoriasis and diabetes. Therefore, psoriasis is a systemic disorder and other comorbidities should be considered in the management of patients with psoriasis. © 201

Improving supply chain collaborations and performance of inefficient supply chain

Modern manufacturing enterprises are required to collaborate by their business partners through their business process operations such as design, manufacture, distribution, and aftersales services. And furthermore performance evaluation is of great importance for effective supply chain man agement. Therefore, DEA can help companies to remove some of the in efficiencies in operational processes in order to become more effective. The current paper develops one approach for determining the DEA projections for inefficient supply chains. Meanwhile this approach aims at providing an easy, efficient and more practical approach based on the performance evaluation for the multi-member supply chain. And ultimately, this model is illustrated by an numerical example of Chinese commercial bank, and case study application to provide of machine-making supply chain

Comparison of the thickening of donor skin graft with conventional method (using vaseline gas) and platelet-rich plasma topical application

Background: Healing involves complex processes that are not yet fully known. The wound healing process consists of three stages. In all these stages, normal wound healing requires platelet activation, release of cytokines and growth hormones, and chemotaxis and cell differentiation. Platelets play a key role in homeostasis and wound healing and growth factor production of more than 30 carried out by them. Platelets regulate the healing process with their chemotactic effect. Antilogous PRP platelet count in about 3 to 5 times increase and consequently also increases the number of growth factors, for this reason, they are being used in surgical procedures and clinical therapy. Methods: At Ilam Medical Center in Imam Khomeini Hospital, 20 patients with two similar donor graft sites were gradually selected to participate in a clinical trial from January to March 2017. The two regions have the same skin graft patients, an area of Honor conventional and other areas with the topical administration of platelet-rich plasma That immediately after surgery and in the days after the fifth and eleventh, eightieth and after washing the wound with a topical serum Physiology rubbed on the wound and thus treated The rate of wound healing clinically and using X-ray photochecked and compared. Results: Seven are male and thirteen are female and the age range of patients is between 17 and 67 years. After collecting wound healing times in two groups, we used the means comparison method to evaluate the effect of PRP on wound healing rate and analyzed the results (T-Test). Because the data followed a normal distribution, we used the Independent T-test method, which resulted in 0.416, which was higher than the alpha level equal to 0.05. Conclusion: In this study, we found that PRP had a positive effect on wound healing time and increased the speed of wound healing. It is suggested that the effect of the PRP method on various organs that have not been tested before, be discussed in future studies. © 2022 Tehran University of Medical Sciences.

NEBL and AKT1 maybe new targets to eliminate the colorectal cancer cells resistance to oncolytic effect of vesicular stomatitis virus M-protein

This study compares the oncolytic effect of vesicular stomatitis virus (VSV) wild type and M51R M-protein on the colorectal tumors of different invasive intensity on SW480 and HCT116 cell lines and 114 fresh colorectal cancer primary cell cultures. Fresh tumor samples were divided into two groups of lower stages (I/II) and higher stages (III/IV) regarding the medical records. The presence of two mutations in the PIK3CA gene and the expression of NEBL and AKT1 genes were evaluated. The cells were transfected with a plasmid encoding VSV wild-type and M51R mutant M-protein. Results showed either wild type or M51R mutant can kill SW480 and stage I/II primary cultures while mutant M-protein had no apoptotic effects on HCT116 cells and stage III/IV primary cultures. NEBL and AKT1 expression were significantly higher in resistant cells. Elevated caspase-9 activity confirmed that the intrinsic apoptosis pathway is the reason for cell death in lower-stage cells. Different tumors from the same cancer exhibit different treatment sensitivity due to genetic difference. NEBL and AKT1 gene expression may be responsible for this difference, which may be the target of future investigations. Therefore, tumor staging should be considered in oncolytic viral treatment as an interfering factor. © 202

Prevalent latent human cytomegalovirus genotype b2 in biopsy samples of gastric cancer

Aim: Genotyping and prevalence of human cytomegalovirus (HCMV) in gastrointestinal tract remains unclear. Objective: Characterization of HCMV and its viral load in samples of patients with gastric cancer (GC) in northeast Iran. Methods: A total of 21 biopsies were collected from patients with GC. HCMV was detected and genotyped using multiplex nested PCR. Quantitative real-time PCR has been used to determine the viral load. Staining was performed to detect viral inclusions. Results: 76.19 of the samples had HCMV genotypic b2 with viral load <0.1 IU/μl. 66.67 of patients were positive for H. pylori. Conclusion: Multiplex nested-PCR method can detect CMV populations with low viral loads in GC biopsies. For the first time, it was determined that the genotype b2 of HCMV is prevalent in the gastrointestinal tract. © 2020 © 2020 Future Medicine Ltd

Acute renal failure and hemolytic uremic syndrome in overdose with n-acetyl cysteine after acetaminophen poisoning

Context: Acetylcysteine is an effective treatment for acetaminophen poisoning. The preparation and dose calculation of acetylcys-teine is associated with medical errors. The prevalence of this error is 34 globally. Case report: A 15-year-old girl took an overdose of acetaminophen in a suicide attempt. Acetylcysteine intravenous was ordered. Due to the medication error by the nurse, she received a 10-fold overdose of intravenous acetylcysteine in both initial loading dose and maintenance dose, at first day. On the second day, the patient showed abdominal pain, nausea, vomiting, and elevated liver enzymes. Her hemoglobin, hematocrit, and platelet quickly decreased. Subsequently, she developed oliguria, anuria, and rising serum creatinine levels. The patient was diagnosed with uremic hemolytic syndrome. She underwent hemodialysis and was treated with plasmapheresis, blood transfusions, and platelets. Discussion: The effects of acetaminophen poisoning and acetylcysteine overdose may be much more severe and have a greater impact on patient survival than each poisoning alone. Timely and accurate treatment measures can help prevent long-term side effects. © 2021, Author(s)

Investigating the relationship between the number and activity of natural killer cells with increased cytomegalovirus and CMV disease after kidney transplantation

Background: Cytomegalovirus (CMV) infections caused by the cytomegalovirus are one of the most common problems in patients after kidney transplant. We examined the association of the relationship between the number and activity of natural killer cells with increased cytomegalovirus and its related disease after kidney transplantation.Material and methods: In this analytical study, 58 new transplant patients in the Labbafinejad Hospital, who did not have any evidence of CMV infection, were evaluated based on the number and percentage of CD56+/16+, CD56+/16-, and CD69+ Natural Killer (NK) cells.Results: The results of this study showed that CD16+ and CD56+ cells in the group of CMV Ag-positive patients are less than negative patients (p = 0.003) and the difference between the two groups are significant (p = 0.01). However, CD69+ cells did not differ significantly between the two groups (p = 0.1). Moreover, the absolute number of CD16+ and CD56+ cells declined significantly after infection with CMV unlike the CMV Ag - group(p = 0.003). Discussion: These results indicate that kidney transplant patients suffering from CMV infection after transplantation have a significantly reduced total number of NK cells. On the other hand, a slight decrease in the number of NK subgroups was observed with an increase in the peak serum levels of cyclosporine. As a consequence of these findings, it can be assumed that more dosage and a higher level of the drug will result in more severe immunosuppression and, consequently, increased susceptibility to CMV infections. Thus, taking the right dose of the drug would prevent viral infections and immune system from over-activation

Association of IL-15 and IP-10 Serum Levels with Cytomegalovirus Infection, CMV Viral Load and Cyclosporine Level after Kidney Transplantation

Background: Cytomegalovirus (CMV) infection is the most common complications following kidney transplantation. Natural killer (NK) cells demonstrated critical anti-viral role in controlling and elimination of CMV after transplantation. Interleukin-15 (IL-15) is a pleiotropic cytokine that promotes the activity of NK cells and strengthens the acquired immune system. Also, IP10 (CXCL10) is a chemotactic factor which regulates NK cell recruitment and antiviral immune response. We aimed to determine the correlation between the serum levels of IL-15 and IP-10 cytokines with CMV infection, CMV viral load, and cyclosporine as a major immunosuppressive treatment after transplantation. Methods: Fifty-eight kidney transplant recipient patients without evidence of CMV virus disease before transplantation surgery were included in the study. From the day of transplant surgery, the patients were evaluated based on the presence of CMV Ag pp65, CMV viral load, serum levels of IL-15 & IP-10, Cyclosporine levels (C0 & C2), Glomerular Filtration Rate (GFR), and hematological & biochemical Index, up to 75 days. Results: Comparison analysis of serum levels of IL-15 and IP-10 showed no significant association with CMV infection in kidney transplant recipients. In addition, CMV viral load and cyclosporine levels at C0 and C2 did not affect patients' IL-15 and IP-10 levels. Conclusions: The levels of IP-10 and IL-15 cytokines are not affected with CMV infection, even if a viral infection occurs in the early days after transplantation or long afterwards. In addition, taking the different levels of cyclosporine did not affect the cytokines levels. Other mechanisms may play a role in maintaining the levels of these cytokines. © 2021, Reports of Biochemistry and Molecular Biology. All Rights Reserved
