Pharmacological and surgical treatments have been mainly targeted on lowering IOP by decreasing aqueous humor production or increasing aqueous humor outflow. Stem cell therapies may open new frontiers in regenerative ophthalmology branch. In POAG there is a strong association with pathologic degeneration of the trabecular meshwork (TM) and regenerative cell-therapy approaches have been focused mainly on modulation of the degeneration. Many different adult stem cell types have been discovered in different parts of the eye such as the corneal endothelium (CE) and anterior non-filtering portion of the TM called Schwalbe’s ring region. These stem cells may supply new cells for the TM and may regenerate the TM structure thus reducing IOP and restore the homeostatic function of the eye. In this paper, we report the studies’ latest findings and present our perspective on approaches that seem promising in the management of POAG.","PeriodicalId":41597,"journal":{"name":"Transplant Research and Risk Management","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/TRRM.S160229","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68494685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Effect of pretransplant depression on neutrophil recovery following hematopoietic stem cell transplantation","authors":"Maria Tavakoli-Ardakani, N. Beyraghi, Mahtabalsadat Mirjalili, Ehsan Mirzaei, M. Mehrpooya","doi":"10.2147/TRRM.S194011","DOIUrl":"https://doi.org/10.2147/TRRM.S194011","url":null,"abstract":"Purpose: Pre-transplantation depression is known to exert negative effects on clinical outcomes after hematopoietic stem cell transplantation (HSCT). Accumulating evidence shows a bidirectional association between inflammation and depression. Systemic inflammation can affect clinical outcomes after transplantation, such as time to engraftment. This study evaluated the effect of pre-transplantation depression and serum level of proinflammatory and anti-inflammatory cytokines on clinical outcomes such as neutrophil recovery time and mortality in patients undergoing HSCT. Patients and methods: In this cross-sectional study, we recruited 73 patients who were autologous or allogeneic HSCT candidates. Hospital Anxiety and Depression Scale questionnaire was used to assess depression in the first 2 days after their hospital admission. Serum levels of IL-10, IL-6, and hs-CRP were measured at the same time. Neutrophil engraftment time, length of hospitalization, rate of mortality, relapses, readmissions, and occurrence of major complications following HSCT in a 1-year follow-up period were recorded as comparative outcomes. Results: Thirty-five patients with depression and 38 patients without depression participated in the study. Among the related outcomes, time of engraftment (P=0.020) and mortality rate (P=0.059) were statistically different between the two groups. Depressed patients had longer neutrophil engraftment time and higher mortality rate 1 year following transplantation (14.14±3.95 days and 31.43) in comparison to non-depressed patients (12.21±2.81 days and 13.16). Depressed patients showed significantly higher serum levels of IL-6 and IL-6-to-IL-10 ratio compared to non-depressed participants (P<0.001 and P=0.004). Conclusion: According to the results, pre-transplant depression can negatively impact neutrophil recovery time and mortality rate following HSCT. Higher levels of inflammatory factors in depressed patients might be one of the mechanisms that negatively affect clinical outcomes after HSCT. © 2019 Tavakoli-Ardakani et al.","PeriodicalId":41597,"journal":{"name":"Transplant Research and Risk Management","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/TRRM.S194011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47791894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Greenway","doi":"10.2147/TRRM.S143063","DOIUrl":"https://doi.org/10.2147/TRRM.S143063","url":null,"abstract":": Improved long-term survival following solid-organ transplantation (SOT) has remained elusive over the past several decades, despite significant advances in early survival. The microbiome refers to the genetic material belonging to microbes that live in an ecological balance with the human host, and its importance in human health is increasingly recognized. Extensive research pertaining to the human microbiome has demonstrated that compositional changes in the microbiome can contribute to such diseases as inflammatory bowel disease, metabolic syndrome, and (recently) many of the comorbidities that develop after SOT. It is suggested that the microbiome may be an important environmental variable that could influence health outcomes after SOT. Many factors related to SOT, including end-stage organ disease, surgery, and the use of antimicrobial prophylaxis and immunosuppressive drugs, have been shown to affect microbial composition and function negatively. These alterations could compromise health outcomes after SOT through the dysregulation of important host–microbe interactions, including the modulation of local and systemic host immune function by the gut microbiome, and could contribute to morbidity and even allograft rejection. Such interventions as synbiotic therapy and fecal microbiota transplantation have the potential to prevent or reverse disruption of the microbiome related to SOT and thereby improve the longevity of transplant recipients. Although microbiome research is still a relatively new field, progress is accelerating exponentially. Future research on host– microbiome interactions in the context of SOT will facilitate the development of microbiome-directed treatments to improve patient outcomes on pre- and post-SOT.","PeriodicalId":41597,"journal":{"name":"Transplant Research and Risk Management","volume":"10 1","pages":"1-11"},"PeriodicalIF":0.9,"publicationDate":"2018-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/TRRM.S143063","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45332348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neutrophil gelati-nase-associated lipocalin (NGAL) has been validated as a biomarker for posttransplant acute kidney injury. This observational study aimed to assess the effectiveness of urinary NGAL as a predictive marker of delayed graft function. Materials and methods: Forty-three consecutive patients who received renal transplant were included in the study. Urine samples were collected before transplant (if available) and at days 1, 3, 7, 14, and 30 after transplant, and urinary NGAL levels were quantified by enzyme-linked immunosorbent assay. Results: Urinary NGAL progressively decreased after transplant in patients with both delayed and immediate graft function. However, urinary NGAL concentration remained significantly higher in the presence of delayed graft function in the first 14 days after transplant. The area under the receiver operating characteristic curve showed that the ability of urinary NGAL to predict delayed graft function was accurate at 1st and 3rd days after transplant. Conclusion: The relative decrease of urinary NGAL concentration rather than its absolute value may be relevant to predict delayed graft function after renal transplant. In particular, urinary NGAL area under the curve for 3 days seems to be a more valuable parameter of decision making in the early posttransplant period.","PeriodicalId":41597,"journal":{"name":"Transplant Research and Risk Management","volume":"9 1","pages":"15-21"},"PeriodicalIF":0.9,"publicationDate":"2017-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/TRRM.S122090","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68494519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
