BMC Urol 2022; 22:46. [PMID: 35346141 PMCID: PMC8962082 DOI: 10.1186/s12894-022-00988-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Accepted: 03/03/2022] [Indexed: 11/30/2022] Open
Abstract
Introduction To analyze the risk factors for progression of urolith associated with obstructive urosepsis to severe sepsis or septic shock, we had done the retrospective cross-sectional study, which would facilitate the early identification of high-risk patients. Materials and methods Datas were retrospectively reviewed from 160 patients, suffering from obstructive urosepsis associated with urolith between December 2013 and December 2019. There were 49 patients complicating by severe sepsis (severe sepsis group), 12 patients complicating by septic shock (septic shock group), and 99 patients without progressing to severe sepsis or septic shock (sepsis group). The data covered age, gender, BMI (body mass index), time interval from ED (emergency department) to admission, WBC count (white blood cell count), NLR (neutrophil/lymphocyte ratio), HGB (hemoglobin), etc. Datas were analyzed by univariate analyses and multivariate logistic regression analysis. The corresponding nomogram prediction model was drawn according to the regression coefficients. Results Univariate analysis showed that the differences of age, the time interval from ED to admission, history of diabetes mellitus, history of CKI (chronic kidney disease), NLR, HGB, platelet count, TBil (total bilirubin), SCr (serum creatinine), ALB (albumin), PT (prothrombin time), APTT (activated partial thromboplastin time), INR (international normalized ratio), PCT (procalcitonin), and positive rate of pathogens in blood culture were statistically significant (P < 0.05). Multivariatelogistic regression analysis showed that age, SCr, and history of CKI were independent risk factors for progression to severe sepsis, or septic shock (P < 0.05). Conclusions Aged ≥ 65 years, SCr ≥ 248 mol/L, and history of CKI were independent risk factors for progression of urolith associated with obstructive urosepsis to severe sepsis or septic shock. We need to pay more attention to these aspects, when coming across the patients with urolithic sepsis.

The Influence of Oxidative Stress on Neurological Outcomes in Spontaneous Intracerebral Hemorrhage. Biomolecules 2021; 11:biom11111615. [PMID: 34827613 PMCID: PMC8615528 DOI: 10.3390/biom11111615] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Revised: 10/25/2021] [Accepted: 10/28/2021] [Indexed: 11/17/2022] Open
Abstract
Spontaneous intracerebral hemorrhage (ICH) causes, besides the primary brain injury, a secondary brain injury (SBI), which is induced, amongst other things, by oxidative stress (OS) and inflammation, determining the patient’s outcome. This study aims to assess the impact of OS in plasma and cerebrospinal fluid (CSF) on clinical outcomes in patients with ICH. A total of 19 ICH (volume > 30 cc) patients and 29 control patients were included. From day one until seven, blood and CSF samples were obtained, and ICH volume was calculated. OS markers, like malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), glutathione-sulfhydryl (GSH), and the total antioxidant status (TAS) were measured. Clinical data on treatment and outcome were determined. Patients with mRS ≤ 4 showed significantly elevated SOD and GSH-Px levels in plasma compared to patients with poor CO (p = 0.004; p = 0.002). Initial increased TAS in plasma and increased MDA in CSF were linked to an unfavorable outcome after six months (p = 0.06, r = 0.45; p = 0.05, r = 0.44). A higher ICH volume was associated with a worse outcome at week six (p = 0.04, r = 0.47). OS plays a significant role in SBI. Larger ICHs, elevated MDA in CSF, and TAS in plasma were associated with a detrimental outcome, whereas higher plasma-SOD and -GSH-Px were associated with a favorable outcome.

The Serum Prolidase Enzyme Activity as a Biomarker for Evaluation of the Subclinical Vascular Damage in Children with Epilepsy. Ann Indian Acad Neurol 2021; 23:787-791. [PMID: 33688128 PMCID: PMC7900735 DOI: 10.4103/aian.aian_640_19] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2019] [Revised: 12/23/2019] [Accepted: 02/07/2020] [Indexed: 01/14/2023] Open
Abstract
Backgroud: Epilepsy is a chronic medical condition requiring long term or even lifelong therapy. Various researches have shown that epilepsy patients have vascular risk factors such as abnormal lipids, insulin, elevated oxidative stress, chronic inflammation, and subclinical atherosclerosis. Objectives: The purpose of the present study was to determine serum prolidase enzyme activity as a biomarker in children taking antiepileptic drug treatment through comparison with control cases. Materials and Methods: The present study group consists of 61 children (20 females, 41 males) with epilepsy and a control group was formed of 32 healthy individuals (14 females, 18 males). Aspectrophotometric method was used to measure serum prolidase enzyme activity. Results: The epilepsy group demonstrated statistically significantly higher prolidase enzyme activity values when compared with the control group (P = 0.003). It was measured that the serum TOS and OSI values were significantly elevated in patients with epilepsy compared to controls (P < 0.001). However, serum TAS values were significantly lower in the epilepsy group than in the control group (P = 0.032). Conclusions: These results supported that epileptic patients taking the antiepileptic treatment had increased serum prolidase enzyme activity, suggesting that it may show an increased risk of subclinical vascular damage related to both chronic inflammation and fibrotic process associated with degenerated collagen turnover. Therefore, serum prolidase enzyme activity could be considered a useful biomarker for evaluation of the subclinical vascular damage in children with epilepsy on some antiepileptic drugs.

Changes of complement and oxidative stress parameters in patients with acute cerebral infarction or cerebral hemorrhage and the clinical significance. Exp Ther Med 2019; 19:703-709. [PMID: 31853325 PMCID: PMC6909527 DOI: 10.3892/etm.2019.8229] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2019] [Accepted: 11/13/2019] [Indexed: 12/18/2022] Open
Abstract
Changes of complement and oxidative stress parameters in patients with acute cerebral infarction (ACI) or cerebral hemorrhage (CH), and their clinical significance were explored. A total of 122 patients with ACI or CH admitted to the People's Hospital of Zhangqiu Area from August 2018 to September 2019 were collected. There were 59 ACI patients assigned into a cerebral infarction group (CIG) and further 63 CH patients in a cerebral hemorrhage group (CHG). Additionally, 53 healthy people in physical examination during the same period were enrolled as a control group (CG). Both the CIG and the CHG were treated with edaravone, Xueshuantong, brain protein hydrolysates, aspirin and statin-related drugs. The levels of complement C3, complement C4, superoxide dismutase (SOD), and total antioxidant capacity (TAC) were determined. Receiver operating characteristic (ROC) curves were employed to analyze the predictive value of C3, C4, SOD and TAG in ACI and CH, and logistic regression was used to analyze the risk factors of stroke. Both CIG and CHG showed higher C3 level, and lower C4, SOD and TAC levels than the CG. The NIHSS <4 group and the NIHSS ≥4 group showed higher hs-C3 level, and lower SOD and TAC levels than the CG (all P<0.05), and the NIHSS <4 group showed lower C3 level and lower SOD and TAC levels than the NIHSS ≥4 group (all P<0.05). Hypertension and hyperlipidemia were independent risk factors of stroke. The serum complement and oxidative stress parameters in patients with ACI or CH can be determined through routine examination, and the nerve function deficit could be assessed by determining the complement and oxidative stress parameters in clinical practice.

Abstract
Commonly observed in older community persons, dilated perivascular spaces (dPVSs) are thought to represent an emerging MRI marker of cerebral small vessel disease, but their clinical significance is uncertain. We examined the longitudinal relationship of dPVS burden with risk of incident stroke, ischemic stroke, and intracerebral hemorrhage (ICH) in the 3C-Dijon population-based study (N = 1678 participants, mean age 72.7 ± 4.1 years) using Cox regression. dPVS burden was studied as a global score and according to dPVS location (basal ganglia, white matter, hippocampus, brainstem) at the baseline. During a mean follow-up of 9.1 ± 2.6 years, 66 participants suffered an incident stroke. Increasing global dPVS burden was associated with a higher risk of any incident stroke (hazard ratio [HR], 1.24; 95% CI, [1.06-1.45]) and of incident ICH (HR, 3.12 [1.78-5.47]), adjusting for sex and intracranial volume. Association with ICH remained significant after additionally adjusting for vascular risk factors and for other cerebral small vessel disease MRI markers. High dPVS burden in basal ganglia and hippocampus, but not in white matter or brainstem, were associated with higher risk of any stroke and ICH.

Abstract
Objective Oxidative stress (OS) and inflammation are considered responsible for the pathogenesis of epilepsy. Prolidase has an extremely important role in proline recycling for collagen synthesis. Higher than normal proline levels have been shown to increase OS. Furthermore, prolidase activity is associated with inflammation during fibrotic process. No study has yet investigated the relationship between epilepsy and prolidase enzyme activity (PEA). In this study, we aimed to contribute to the existing literature by assessing postictal PEA levels, which are correlated with inflammation and OS, to determine whether PEA levels may be used as a biomarker for epilepsy. Materials and Methods This study included patients with epilepsy who presented to the emergency department within first 6 h of a seizure. Results The epileptic group included 27 patients (16 males, 11 females) and the control group included 31 healthy individuals (11 males, 20 females). The mean age of the epilepsy (n=27) and healthy control group (n=31) was 43.1±20.2 and 51.9±21 years, respectively. Serum PEA levels were 1171.90±343.3 in the epileptic group and 1137.1±295.6 in the control group. There were no significant differences between two groups (p>0.05). Conclusion Our study results suggest that although PEA is an enzyme associated with OS and inflammation, it is still not an ideal biomarker for epileptic patients. This study is important because it investigated PEA in patients with idiopathic epilepsy for the first time.

Abstract
The Notch signaling pathway is a crucial regulator of numerous fundamental cellular processes. Increasing evidence suggests that Notch signaling is involved in inflammation and oxidative stress, and thus in the progress of cerebrovascular diseases. In addition, Notch signaling in cerebrovascular diseases is associated with apoptosis, angiogenesis and the function of blood-brain barrier. Despite the contradictory results obtained to date as to whether Notch signaling is harmful or beneficial, the regulation of Notch signaling may provide a novel strategy for the treatment of cerebrovascular diseases.

Abstract
Hemorrhagic stroke is a common and severe neurological disorder and is associated with high rates of mortality and morbidity, especially for intracerebral hemorrhage (ICH). Increasing evidence demonstrates that oxidative stress responses participate in the pathophysiological processes of secondary brain injury (SBI) following ICH. The mechanisms involved in interoperable systems include endoplasmic reticulum (ER) stress, neuronal apoptosis and necrosis, inflammation, and autophagy. In this review, we summarized some promising advances in the field of oxidative stress and ICH, including contained animal and human investigations. We also discussed the role of oxidative stress, systemic oxidative stress responses, and some research of potential therapeutic options aimed at reducing oxidative stress to protect the neuronal function after ICH, focusing on the challenges of translation between preclinical and clinical studies, and potential post-ICH antioxidative therapeutic approaches.

Abstract
Stroke remains an important health and social challenge. The present study investigated whether blood pressure (BP) parameters and circulating levels of nitric oxide metabolites (NOx) and adrenomedullin (AM) may predict clinical outcomes of stroke. Patients (n=76) diagnosed with acute ischemic stroke were admitted to the stroke unit and clinical history data and monitored parameters were recorded. Blood plasma was collected at days 1, 2, and 7 to measure NOx and AM levels. Infarct volume, neurological severity [on the National Institutes of Health Stroke Scale (NIHSS)], and functional prognosis (on the Rankin scale) were measured as clinical outcomes. Patients with higher BP had more severe symptoms (NIHSS >3; P<0.01) and BP variability predicted neurological severity and growth of infarct volume. NOx values were significantly lower in stroke patients than in healthy controls (P<0.01). An increase in NOx levels from day 1 to day 2 was beneficial for the patients as measured by NIHSS at 7 days and 3 months, and by Rankin at 3 months [odds ratio (OR), 0.91] whereas a steep increase from day 2 to day 7 was detrimental and associated with an increase in infarct volume (OR, 35.3). AM levels were significantly higher in patients at day 1 and 2 than in healthy individuals (P<0.01) and these levels returned to normal at day 7. Patients with high AM levels at day 2 had significantly higher NIHSS scores measured at day 1 (P<0.05) and 7 (P<0.01). A receiving operating characteristic curve analysis identified that AM levels at day 2 of >522.13 pg/ml predicted increased neurological severity at day 7 (area under the curve=0.721). Multivariate logistic regression indicated that AM levels at day 2 predicted increased neurological severity at 7 days and at 3 months. BP parameters and changing levels for NOx and AM predicted long-term clinical outcomes as measured by infarct volume, neurological severity scale, and functional prognosis.
