[PMID: 38948643 PMCID: PMC11209322 DOI: 10.5606/tftrd.2024.13946] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Accepted: 12/04/2023] [Indexed: 07/02/2024] Open
Abstract
Objectives: The study aimed to analyze the relationship between serum adiponectin concentration, Mediterranean diet (MD) adherence, and Dietary Approaches to Stop Hypertension (DASH) diet adherence in patients with spinal cord injury (SCI). Patients and methods: Thirty-three SCI patients (21 males, 12 females; median age: 33 years; range, 18 to 65 years) and 33 age-, sex-, and body mass index-matched healthy controls (21 males, 12 females; median age: 33 years; range, 18 to 64 years) were included in this cross-sectional study between March 2021 and March 2022. Serum adiponectin concentrations of all participants were measured. Body weight, height, and neck, hip, waist, and mid-upper arm circumferences were measured. Twenty-four-hour dietary records were obtained by the researchers for evaluation of the nutritional status. The DASH diet score and MD score were measured for each participant. Results: Most of the cases of SCI were due to motor vehicle collisions (n=12, 36.4%) and complete paraplegic. Mid-upper arm circumference, waist circumference, hip circumference, and neck circumference of the patient group were significantly higher than the control group (p=0.020, p=0.002, p=0.042, and p<0.001, respectively). Mediterranean diet scores and DASH diet scores of the patient group were significantly higher than the control group (p<0.001 and p=0.031, respectively). Serum adiponectin concentration of patients was significantly higher than the control group (p=0.049). No correlation was detected between adiponectin concentration, MD score, and DASH diet score in both groups. Conclusion: Although correlation analysis in the current research did not show significant relation between nutrition and adiponectin concentrations, nutrition of patients with SCI, as demonstrated by higher adherence to MD and DASH, may have provided positive effects on adiponectin concentrations. Future studies focused on the effect of a healthy diet intervention on serum adiponectin concentration is warranted.

Cui Z, Wang S, Hao Y, Chen Y. Higher serum β2-microglobulin is a predictive biomarker for cognitive impairment in spinal cord injury. PeerJ 2023; 11:e15372. [PMID: 37193029 PMCID: PMC10183166 DOI: 10.7717/peerj.15372] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 04/18/2023] [Indexed: 05/18/2023] Open
Abstract
Objective Recent studies have suggested that high levels of β2-microglobulin are linked to cognitive deterioration; however, it is unclear how this connects to spinal cord injury (SCI). This study sought to determine whether there was any association between cognitive decline and serum β2-microglobulin levels in patients with SCI. Methods A total of 96 patients with SCI and 56 healthy volunteers were enrolled as study participants. At the time of enrollment, specific baseline data including age, gender, triglycerides (TG), low-density lipoprotein (LDL), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), smoking, and alcohol use were recorded. Each participant was assessed by a qualified physician using the Montreal cognitive assessment (MoCA) scale. Serum β2-microglobulin levels were measured using an enzyme-linked immunosorbent assay (ELISA) reagent for β2-microglobulin. Results A total of 152 participants were enrolled, with 56 in the control group and 96 in the SCI group. There were no significant baseline data differences between the two groups (p > 0.05). The control group had a MoCA score of 27.4 ± 1.1 and the SCI group had a score of 24.3 ± 1.5, with the difference being significant (p < 0.05). The serum ELISA results revealed that the levels of β2-microglobulin in the SCI group were considerably higher (p < 0.05) than those in the control group (2.08 ± 0.17 g/mL compared to 1.57 ± 0.11 g/mL). The serum β2-microglobulin level was used to categorize the patients with SCI into four groups. As serum β2-microglobulin levels increased, the MoCA score reduced (p < 0.05). After adjustment of baseline data, further regression analysis showed that serum β2-microglobulin level remained an independent risk factor for post-SCI cognitive impairment. Conclusions Patients with SCI had higher serum levels of β2-microglobulin, which may be a biomarker for cognitive decline following SCI.

Front Neurol 2023; 14:1120446. [PMID: 36949855 PMCID: PMC10025340 DOI: 10.3389/fneur.2023.1120446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Accepted: 02/13/2023] [Indexed: 03/08/2023] Open
Abstract
Objective Neutrophil gelatinase-associated lipoprotein (NGAL), a protein encoded by the lipocalcin-2 (LCN2) gene, has been reported to be involved in multiple processes of innate immunity, but its relationship with spinal cord injury (SCI) remains unclear. This study set out to determine whether NGAL played a role in the development of cognitive impairment following SCI. Methods At the Neck-Shoulder and Lumbocrural Pain Hospital, a total of 100 SCI patients and 72 controls were enrolled in the study through recruitment. Through questionnaires, baseline data on the participants' age, gender, education level, lifestyle choices (drinking and smoking) and underlying illnesses (hypertension, diabetes, coronary heart disease, and hyperlipidemia) were gathered. The individuals' cognitive performance was evaluated using the Montreal Cognitive Scale (MoCA), and their serum NGAL levels were discovered using ELISA. Results The investigation included 72 controls and 100 SCI patients. The baseline data did not differ substantially between the two groups, however the SCI group's serum NGAL level was higher than the control group's (p < 0.05), and this elevated level was adversely connected with the MoCA score (p < 0.05). According to the results of the ROC analysis, NGAL had a sensitivity of 58.24% and a specificity of 86.72% for predicting cognitive impairment following SCI. Conclusions The changes in serum NGAL level could serve as a biomarker for cognitive impairment in SCI patients, and this holds true even after taking in account several confounding variables.

Netrin-1: A Serum Marker Predicting Cognitive Impairment after Spinal Cord Injury. DISEASE MARKERS 2022; 2022:1033197. [PMID: 35493300 PMCID: PMC9050267 DOI: 10.1155/2022/1033197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Revised: 03/27/2022] [Accepted: 03/31/2022] [Indexed: 11/28/2022]
Abstract
Objective Although cognitive impairment has received more attention in recent years as a result of spinal cord injury (SCI), the pathogenic process that causes it is still unknown. The neuroprotective effects of Netrin as a family of laminin-related secreted proteins were discovered. The purpose of this study was to determine the changes of serum Netrin-1 after SCI and its relationship with cognitive impairment. Methods 96 SCI patients and 60 controls were included in our study. We collected baseline data from all participants, measured their serum Netrin-1 levels, and followed up their cognitive levels 3 months later. Results The clinical baseline values between the control and SCI groups were not significantly different (p > 0.05). However, the serum Netrin-1 level in the SCI group was significantly lower than that in the control group (528.4 ± 88.3 pg/ml vs. 673.5 ± 97.2 pg/ml, p < 0.05). According to the quartile level of serum Netrin-1 level in the SCI group, we found that with the increase of serum Netrin-1 level, the MoCA score also increased significantly (p < 0.001), indicating that the serum Netrin-1 level was positively correlated with the MoCA score after SCI. After controlling for baseline data, multiple regression analysis revealed that Netrin-1 remained an independent risk factor for cognitive impairment after SCI (=0.274, p = 0.036). Conclusions Netrin-1 may be a neuroprotective factor for cognitive impairment, which may serve as a serum marker to predict cognitive impairment after SCI.
