Abstract
Abstract
Background
It remains unknown if concomitant left atrial appendage closure (LAAC) at the time of left ventricular assist device (LVAD) surgery can reduce ischemic cerebrovascular accidents.
Purpose
The purpose of this study is to assess the impact of LAAC at LVAD surgery on the incidence of ischemic cerebrovascular accidents.
Methods
Between January 2012 and November 2021, 310 patients underwent LVAD surgery with HeartMate II or III. Out of 310 patients, 98 patients (31.6%) underwent concomitant LAAC. The cohort was divided into two groups: patients with LAAC (Group A, n=98) and without LAAC (Group B, n=212). To minimize device bias, LVAD surgery with HeartWare HVAD device was excluded. The ischemic cerebrovascular accident was defined as ischemic stroke, hemorrhagic stroke or transient ischemic attack. We reviewed early and long-term clinical outcomes. The incidence of ischemic cerebrovascular accidents was compared between two groups using the Kaplan-Meier method. We also investigated if LAAC was associated with ischemic cerebrovascular accidents by Cox proportional hazards analysis.
Results
There were no significant differences in baseline characteristics between two groups including age (Group A: 55.0±12.3 years old, Group B: 56.9±14.1 years old, p=0.26), preoperative CHADS2 score (Group A: 2.40±1.1, Group B: 2.58±1.1, p=0.19) and history of atrial fibrillation (Group A: 42.9%, Group B: 42.5%, p=0.95). In-hospital mortality was not significantly different between the two groups (Group A: 7.1%, Group B: 12.3%, p=0.16). In terms of postoperative complications, there were no significant differences between two groups in requiring extracorporeal membrane oxygenation, re-exploration for bleeding and newly required hemodialysis. Median follow up period was 474 days. Thirty-five patients (11.2%) developed ischemic cerebrovascular accidents (5 patients in Group A and 30 patients in Group B). The rate of freedom from ischemic cerebrovascular accidents in Group A (94.1% at 500 days and 94.1% at 1500 days) was significantly higher than that in Group B (88.2% at 500 days and 77.4% at 1500 days; log rank=0.024). In a Cox proportional hazards regression analysis including LAAC, age, history of atrial fibrillation, diabetes mellitus and Heartmate 3 device implantation, LAAC was associated with reducing the incidence of ischemic cerebrovascular accidents (hazard ratio 0.37, 95% CI 0.13–0.89, p=0.02).
Conclusion
Concomitant LAAC at the time of LVAD surgery can reduce ischemic cerebrovascular accidents without increasing perioperative mortality and complications.

Abstract
The purpose of this research was to investigate the trehalose and vitamin C (Vit C) co-supplementation of freezing media to create a successful cryopreservation protocol for conservation of ovine spermatogonial stem cells (SSCs). SSCs were cryopreserved and cultured with an essential freezing medium containing 200 mM trehalose, 40 µg/mL Vit C, and a combination of both for 3 weeks. Cell viability, colony number and diameter and mRNA levels of Bax, and Bcl-2 genes were evaluated before and after cryopreservation with quantitative real-time PCR. The results showed that cells cryopreserved in freezing medium containing 200 mM of trehalose plus 40 µg/mL Vit C had considerably greater cell viability than the control group (P<0.0001). Up to the 3rd week of cell culture, supplementation of freezing medium with 200 mM trehalose resulted in significantly lower colonies diameters than in the control group. No significant differences were observed during the 1st to 2nd weeks in colony diameter and number of colonies between cells cryopreserved in the freezing medium containing either Vit C or trehalose compared with the control groups. Following thawing, the mRNA level of Bax in the Vit C + trehalose group was drastically lower than in those treated with trehalose or Vit C only (P<0.0001). High expression of Bcl-2 in the 40 µg/mL Vit C group was recorded in the thawed cells compared to the control group (P<0.0001). These findings indicate that the concomitant use of antioxidants and sugar in the freezing medium can improve the quality and viability of SSCs after freezing via different mechanisms. Further studies are needed to clarify apoptosis and cell biomarkers in SSCs during freezing and thawing.

Abstract
Acute T cell-mediated rejection (TCMR) is a major complication after renal transplantation. TCMR diagnosis is very challenging and currently depends on invasive renal biopsy and nonspecific markers such as serum creatinine. A noninvasive metabolomics panel could allow early diagnosis and improved accuracy and specificity. We report, in this study, on urine metabolome changes in renal transplant recipients diagnosed with TCMR, with a view to future metabolomics-based diagnostics in transplant medicine. We performed urine metabolomic analyses in three study groups: (1) 7 kidney transplant recipients with acute TCMR, (2) 15 kidney transplant recipients without rejection but with impaired kidney function, and (3) 6 kidney transplant recipients with stable renal function, using 1H-nuclear magnetic resonance. Multivariate modeling of metabolites suggested a diagnostic panel where the diagnostic accuracy of each metabolite was calculated by receiver operating characteristic curve analysis. The impaired metabolic pathways associated with TCMR were identified by pathway analysis. In all, a panel of nine differential metabolites encompassing nicotinamide adenine dinucleotide, 1-methylnicotinamide, cholesterol sulfate, gamma-aminobutyric acid (GABA), nicotinic acid, nicotinamide adenine dinucleotide phosphate, proline, spermidine, and alpha-hydroxyhippuric acid were identified as novel potential metabolite biomarkers of TCMR. Proline, spermidine, and GABA had the highest area under the curve (>0.7) and were overrepresented in the TCMR group. Nicotinate and nicotinamide metabolism was the most important pathway in TCMR. These findings call for clinical validation in larger study samples and suggest that urinary metabolomics warrants future consideration as a noninvasive research tool for TCMR diagnostic innovation.

Abstract
Although antibody mediated rejection (AMR) accounts for 20-30% of all acute renal allograft rejections, introducing biomarkers for a timely detection of allograft rejection has been remained challenging. This study investigated novel diagnostic biomarkers of AMR by examining of urine proteome in renal transplant patients. Thirty-six patients with kidney transplantation including 22 AMR patients and 14 patients with stable renal function (control group) were enrolled in this study. Urinary samples were collected and Label free quantification (LFQ) proteomics technique was applied on urine samples and data was subjected to Random Forest (RF) algorithm to predict main candidate proteins contributing in AMR. Finally, applicability of candidate diagnostic biomarkers was evaluated in new sets of AMR subjects, stable patients and healthy volunteers. A total of 1020 proteins were detected in urine proteome. RF algorithm predicted 20 differentially expressed proteins with the highest sensitivity and specificity and combination of EGF, COL6A, and NID-1 was identified as possible panel for early diagnosis of AMR. Applicability of EGF as diagnostic biomarker was validated in urine samples of independent set of AMR subjects. This is the first urinary proteomics study in AMR patients demonstrating that urinary EGF might be used as early diagnostic biomarker for AMR. SIGNIFICANCE: Renal antibody mediated rejection (AMR) accounts for 20-30% of all acute rejections of allografted kidneys. Although several possible biomarkers have been proposed to predict AMR, ineffectiveness of current urinary biomarkers in early diagnosing of AMR patients and in distinguishing AMR subjects from patients with stable kidney function casts doubts on their applicability in clinic. Here for the first time and based on the analysis of urinary proteome we showed that uEGF and uEGF/Cr might be candidate biomarkers to predict AMR with high diagnostic power.

Abstract
INTRODUCTION Lupus nephritis (LN) is one of the most serious complications of systemic lupus erythematous (SLE). With no specific clinical or laboratory manifestation to predict response to treatment, this study was aimed to provide a panel of predictive biomarkers of response before initiation of treatment. METHODS Liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis was performed on plasma and urine samples of 11 patients with biopsy proven proliferative LN at the time of biopsy. Unsupervised principal component analysis (PCA), orthogonal projection to latent structures discriminant analysis (OPLS-DA), gene ontology annotation and protein mapping were performed on 326 proteins in plasma and 1381 proteins in urine samples. RESULTS Samples of eight patients achieved complete remission and three reached partial remission were analyzed. The mean 24-hour protein excretion was 3259 mg/day and the mean eGFR was 87.73 cc/min. OPLS-DA analysis of plasma samples showed a clear discrimination for complete and partial remission patients. Twenty plasma proteins and ten urine proteins with the highest fold changes and AUCs were selected as candidate biomarkers (IGHV1-18, PI16, IGHD, C3, FCER2, EPS8L2, CTTN, BLVRB). This plasma and urine biomarker panel is involved in oxidative stress, acute inflammation, reduction in regulatory T cells, complement pathway consumption, and proximal tubule bicarbonate reclamation. CONCLUSION Our suggested panel of plasma and urine biomarkers can precisely discriminate patients with possibility of complete response to treatment. It seems that the higher indices of inflammation will associate with better chance of achieving complete remission.

Abstract
Abstract
Background and Aims
Contrast induced nephropathy (CIN) has been reported to be the third foremost cause of acute renal failure. Metabolomics is a robust technique that has been used to identify potential biomarkers for early detection of renal damage after procedures with using contrast media. We aim to analyze the serum and urine metabolites changes, after using contrast for coronary angiography, to determine if metabolomics can use as a tool for early detection of CIN.
Method
Sixty-six patients with positive primary non-invasive diagnostic tests for coronary artery disease (CAD) who were candidate of elective coronary angiography recruited. Spot urine samples collected in the morning before angiography and 4 hours after angiography. Patients with > 0.5 mg/dL creatinine rise compared to baseline were considered as case (CIN group). Urine samples were centrifuged at 3000 rcf for 20 minutes at 4°C to remove the cell debris and after addition of sodium azide to prevent bacterial growth, were stored at -80 degree Celsius in aliquots until required. The mixtures were then transferred to a standard 5 mm NMR tube for analysis. 1H-NMR spectra were acquired at 300 K on a Bruker DRX 500 MHz spectrometer by using Carr–Pucell–Meiboom–Gill (CPMG) technique. For each spectrum, 154 scans were collected into 32K data points using a spectral width of 8389.26 Hz during the relaxation time of 2.5 s.
Results
Structure and outliers of the dataset composed of patient with CIN (n = 10) before angiography and after angiography were evaluated by PCA. A model with two principal components (PC1 and PC2) with R2X = 0.775 and Q2(cum) = 0.487 was obtained .A supervised OPLS-DA model was built to identify discriminative variables between metabolite profiles before and after angiography in patients with CIN. The high level of AUC 0.95 that was obtained from 10-fold cross validation besides decreased R2 (0.0, 0.415) and Q2 (0.0, -0.454) intercepts of 999 random permutations reflects the good validity of this diagnostic model. According to this valid OPLS-DA model, 15 chemical shifts were significant based on VIP > 1 and FC > 1.2. To check these suggested chemical shifts if their changes are due to kidney injury and not caused by contrast agent, a decoy OPLS-DA model was built for non-CIN patients before and after angiography .Two common significant chemical shifts (2.42 and 2.78 ppm) were found in comparison of these two models (i.e. before vs. after angiography in CIN group in compared with before vs. after angiography in non-CIN group) and were excluded from the results. Metabolites corresponding with the remaining list of 12 significant chemical shifts were identified and suggested as early detection biomarker candidates for CIN (Fig 1). The AUC value of a panel of four biomarker candidates were higher than single biomarkers that reflects the value of simultaneous measurement of these four metabolite candidates than single candidates. Figure 2 shows the list of diagnostic metabolite candidates with p < 0.05 . Pathway characterization was used to better understanding of pathophysiology of CIN. As the input data was small list of metabolites, only “Histidine_ lysine_ phenylalanine, tyrosine, proline and tryptophan catabolism” pathway (p < 0.05) was significant and suggested as the most important disturbed pathway in CIN.
Conclusion
Early detection of CIN as early as only 4 hours after using contrast can help better management of these patients. In this study, only after 4 hours passed from using contrast a panel of metabolites could be found in urine of patients who develop CIN, which facilitates early detection of CIN. This is the first study to investigate urine metabolic profile using NMR-based metabolomics for early detection of CIN after coronary angiography. The use of this suggested panel might significantly improve clinical consequences of this harmful complication.

Abstract
Contrast induced nephropathy (CIN) has been reported to be the third foremost cause of acute renal failure. Metabolomics is a robust technique that has been used to identify potential biomarkers for the prediction of renal damage. We aim to analyze the serum and urine metabolites changes, before and after using contrast for coronary angiography, to determine if metabolomics can predict early development of CIN. 66 patients undergoing elective coronary angiography were eligible for enrollment. Urine and serum samples were collected prior to administration of CM and 72 h post procedure and analyzed by nuclear magnetic resonance. The significant differential metabolites between patients who develop CIN and patients who have stable renal function after angiography were identified using U test and receiver operating characteristic analysis was performed for each metabolite candidate. Potential susceptible pathways to cytotoxic effect of CM were investigated by pathway analysis. A predictive panel composed of six urinary metabolites had the best area under the curve. Glutamic acid, uridine diphosphate, glutamine and tyrosine were the most important serum predictive biomarkers. Several pathways related to amino acid and nicotinamide metabolism were suggested as impaired pathways in CIN prone patients. Changes exist in urine and serum metabolomics patterns in patients who do and do not develop CIN after coronary angiography hence metabolites may be potential predictive identifiers of CIN.

Abstract
PURPOSE Long non-coding RNAs (lncRNAs) include a vast portion of human transcripts. They exert regulatory roles in immune responses and participate in diverse biological functions. Recent studies indicated dysregulation of lncRNAs in the process of transplant rejection. In the current study, we aimed at identification of the expression of five lncRNAs (OIP5-AS1, FAS-AS1, TUG1, NEAT1 and PANDAR) in association with the process of transplant rejection. MATERIAL AND METHODS We assessed expression of these lncRNAs in the peripheral blood of 61 kidney transplant receivers including 29 transplant rejected patients and 32 transplant non-rejected patients using real time PCR technique. RESULTS Expression of FAS-AS1 was significantly higher in rejected group compared to non-rejected group in males, however, differences between case and control groups were insignificant among females. For other lncRNAs no significant differences were detected between two study groups. Quantile regression model showed that patients' gender was an important parameter in determination of FAS-AS1 expression (Beta=-9.46, t=-2.82, P=0.007) but not for other lncRNAs expressions. Significant pairwise correlations were detected between expression levels of lncRNAs in a disease related manner. CONCLUSION Based on the higher expression of FAS-AS1 in patients with transplant rejection, this lncRNA might be associated with the pathogenesis of renal transplant rejection.

Abstract
BACKGROUND Protein inhibitors of activated STAT (PIAS) proteins are regarded as negative regulators of cytokine-signaling and potent immunosuppressive proteins. However, their role in the process of organ transplant rejection has not been elucidated. METHODS In the current study, we compared transcript levels of PIAS1 to 4 in the peripheral blood of renal transplant recipients who experienced transplant rejection with those having normal transplant functions. Expression of PIAS1 was significantly higher in nonrejected group compared with the rejected group among male recipients; however, differences were insignificant among female recipients. Expressions of other PIAS genes were not different between study groups. Significant pairwise correlations were found between expression levels of PIAS genes in all study subgroups. The current investigation highlights the role of PIAS1 downregulation in the evolution of graft rejection and potentiates this gene as a predictive marker for transplant fate.

Abstract
Suppressor of cytokine signaling (SOCS) proteins have acknowledged roles in regulation of immune responses. Moreover, their role in the evolution of allograft rejection is being elucidated. In the current investigation, we measured transcript levels of SOCS1-4 in the peripheral blood of a group of renal transplant recipients including both rejected and non-rejected allografts. Expression analyses showed that relative expression of SOCS2 was significantly higher in transplant-rejected male patients compared to non-rejected group. However, such significant difference was not detected between female subjects. Expression of SOCS2 was significantly higher in T-cell-mediated rejection group compared with non-rejected individuals with creatinine rise (Relative expression difference [95% CrI] =6.74 [0.94, 12.65], P = 0.043). Conversely, SOCS4 expression was significantly lower in T-cell-mediated rejection group compared with non-rejected individuals with creatinine rise (Relative expression difference [95% CrI] = -0.35 [-0.63, -0.1], P = 0.008). Patterns of correlations between expression levels of SOCS genes were different in non-rejected group. The obtained results indicate the role SOCS genes in development of allograft rejection.

Abstract
Introduction: Focal segmental glomerulosclerosis (FSGS), the most common primary glomerular disease, is a diverse clinical entity that occurs after podocyte injury. Although numerous studies have suggested molecular pathways responsible for the development of FSGS, many still remain unknown about its pathogenic mechanisms. Two important pathways were predicted as candidates for the pathogenesis of FSGS in our previous in silico analysis, whom we aim to confirm experimentally in the present study. Methods: The expression levels of 4 enzyme genes that are representative of "chondroitin sulfate degradation" and "eicosanoid metabolism" pathways were investigated in the urinary sediments of biopsy-proven FSGS patients and healthy subjects using real-time polymerase chain reaction (RT-PCR). These target genes were arylsulfatase, hexosaminidase, cyclooxygenase-2 (COX-2), and prostaglandin I2 synthase. The patients were sub-divided into 2 groups based on the range of proteinuria and glomerular filtration rate and were compared for variation in the expression of target genes. Correlation of target genes with clinical and pathological characteristics of the disease was calculated and receiver operating characteristic (ROC) analysis was performed. Results: A combined panel of arylsulfatase, hexosaminidase, and COX-2 improved the diagnosis of FSGS by 76%. Hexosaminidase was correlated with the level of proteinuria, while COX-2 was correlated with interstitial inflammation and serum creatinine level in the disease group. Conclusion: Our data supported the implication of these target genes and pathways in the pathogenesis of FSGS. In addition, these genes can be considered as non-invasive biomarkers for FSGS.
