Abstract
STUDY DESIGN We conducted a retrospective, descriptive register study. OBJECTIVE The aim of the study was to present the epidemiological and demographic characteristics of the Swedish spinal cord injury (SCI) population. SETTING Rehabilitation units in Sweden were connected to the National Quality Register for Rehabilitation Medicine (Svenskt Register för Rehabiliteringsmedicin: SveReh). The registry includes data from 26 units around the country. METHODS Information was extracted from SveReh for patients who underwent rehabilitation for a new onset SCI between January 1, 2016, and December 31, 2020. Data regarding gender, age, aetiology, level of injury, neurogenic bowel and/or bladder dysfunction, complications during the primary rehabilitation, and the need for bi-level positive airway pressure, continuous positive airway pressure, or ventilator were analysed. RESULTS Mean age at onset was 56 years, and men were overrepresented (66%). Tetraplegia was more common among traumatic SCI (TSCI) than non-traumatic SCI (NTSCI). The incidence was 11.9-14.8 per million for TSCI and 8.9-11.8 per million for NTSCI. At discharge, 8% of patients needed a breathing aid. Of those who were ventilator-dependent at discharge, 75% had a TSCI. Disturbed bowel and bladder functioning was noted in 58% of patients at discharge. The median time spent at the unit was 40 days, but it was approximately 2 weeks longer for those with a TSCI. CONCLUSIONS Systematic and updated data on the Swedish SCI population show a pattern similar to Scandinavian countries with high age at onset and falls being the main cause of TSCI. The TSCI incidence was lower than in previous studies, and the results for NTSCI were novel.

Abstract
This review describes the incidence rates and trends of traumatic spinal cord injuries (TSCI) and non-traumatic spinal cord injuries (NTSCI) in South Korea. The incidence of NTSCI has increased more rapidly than that of TSCI in recent years. In 2007, TSCI was more common, but by 2020, NTSCI had surpassed TSCI, particularly in older individuals. While men have a higher incidence of both TSCI and NTSCI, the incidence difference by sex is greater in TSCI. The incidence rates of both TSCI and NTSCI are higher in older individuals, particularly those in their 70s and 80s. For TSCI, falls and traffic accidents are the most common causes, with falls being more prevalent in older adults. Cervical SCIs are the most common TSCI, especially in high-income countries like South Korea. Patients with NTSCI predominantly display paraplegia, which is usually associated with non-traumatic causes such as degenerative disorders and tumors. Higher rates of tetraplegia and paraplegia are observed with TSCI and NTSCI, respectively. The neurological levels of injury also differ between TSCI and NTSCI. Overall, SCIs are a growing concern in South Korea and there is a need for targeted interventions for their management and prevention, especially in older age groups.

Incidence and mortality of spinal cord injury from 2008 to 2020: a retrospective population-based cohort study in the Piedmont Region, Italy. Spinal Cord 2023; 61:99-105. [PMID: 35933474 PMCID: PMC9362101 DOI: 10.1038/s41393-022-00842-6] [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: 12/17/2021] [Revised: 07/22/2022] [Accepted: 07/26/2022] [Indexed: 11/10/2022]
Abstract
STUDY DESIGN Retrospective population-based cohort study. OBJECTIVES To determine the incidence and mortality of spinal cord injuries (SCI) in the Piedmont Region of Northwestern Italy. SETTING Publicly-funded SCI rehabilitation centres in the Piedmont Region. METHODS Administrative databases were used to identify individuals at their first admission to a SCI rehabilitation centre from January 1st, 2008 to December 31st, 2020. Cases were stratified by age and aetiology (traumatic SCI, TSCI; non-traumatic SCI, NTSCI). Age- and aetiology-specific incidence rate and person-year mortality rates were calculated for each year. Case lethality was reported as deaths among prevalent cases for each year. RESULTS A total of 892 cases were identified (56.4% TSCI). The average annual crude incidence rate was 17.9 per million population, decreasing from 26.0 in 2008 to 10.8 in 2020. Young adults and the elderly represented the majority of TSCI and NTSCI cases, respectively. Of the 235 individuals who died during the study period, 58.3% had NTSCI. The mortality rate per 1000 person-years decreased from 16.3 in 2009 to 8.5 in 2020, while case lethality more than tripled (from 17.2 in 2009 to 57.1 in 2020). CONCLUSIONS We identified a decreasing trend in SCI incidence and mortality rates, with an increased case lethality over the study period, especially in NTSCI. Given these changes in the epidemiology of SCI, community services offered after rehabilitation should be strengthened to enhance their effectiveness and contribute to increased survival in this population.

Appl Bionics Biomech 2022; 2022:4790344. [PMID: 35498148 PMCID: PMC9054478 DOI: 10.1155/2022/4790344] [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: 02/22/2022] [Revised: 04/02/2022] [Accepted: 04/06/2022] [Indexed: 11/30/2022] Open
Abstract
Objective The present study was designed to study the effect of genistein on spinal cord injury (SCI) in mice and to explore its underlying mechanisms. Methods We established SCI mouse model, and genistein was administered for treatment. We used the Basso, Beattie, and Bresnahan (BBB) exercise rating scale to evaluate exercise recovery, and the detection of spinal cord edema was done using the wet/dry weight method. Apoptosis was determined by TUNEL staining, and inflammation was evaluated by measuring inflammatory factors by an ELISA kit. The expression of M1 and M2 macrophage markers was determined using flow cytometry, and the expression of proteins was detected using immunoblotting. Results Genistein treatment not only improved the BBB score but also reduced spinal cord edema in SCI mice. Genistein treatment reduced apoptosis by increasing Bcl2 protein expression and decreasing Bax and caspase 3 protein expression. It also reduced the expression of inflammatory cytokines (TNF-α, IL-1β, IL-6, and IL-8) in the SCI area of SCI mice. Flow cytometry analysis indicated that genistein treatment significantly decreased the ratio of M1 macrophages (CD45+/Gr-1-/CD11b+/iNOS+) and increased the ratio of M2 macrophages (CD45+/Gr-1-/CD11b+/Arginase 1+) in the SCI area of SCI mice on the 28th day after being treated with genistein. We also found that genistein treatment significantly decreased the expression of TLR4, MyD88, and TRAF6 protein in the SCI area of SCI mice on 28th day after being treated with genistein. Conclusion Our findings suggested that genistein exerted neuroprotective action by inhibiting neuroinflammation by promoting the activation of M2 macrophages, and its underlying mechanisms might be related to the inhibition of the TLR4-mediated MyD88-dependent signaling pathway.

Abstract
Study design A cross-sectional study. Objectives To explore the prevalence of comorbidities, secondary health conditions (SHCs), and multimorbidity in the Finnish population with spinal cord injury (SCI). Setting The data were collected from the Finnish Spinal Cord Injury Study (FinSCI). Participants were identified from three SCI outpatient clinics responsible for the lifelong follow-up of persons with SCI in Finland, (n = 884 participants, response rate; 50%). Methods The FinSCI-questionnaire included a question from the National Study of Health, Well-being, and Service (FinSote) for screening 12 comorbidities. The reference data of the general population for that question were received from the Finnish Institute for Health and Welfare. The Spinal Cord Injury Secondary Condition Scale (SCI-SCS) was used to screen 16 SHCs. The data were analysed with univariate testing and multivariable negative binomial regression modelling. Results The most common comorbidities were high blood pressure/hypertension (38%), back problems (28%), and high cholesterol (22%). The most common SHCs were joint and muscle pain (81%), muscle spasms (74%), chronic pain (71%), and bowel problems (71%). The prevalence of comorbidities was highest among persons aged ≥76 years (mean; 2.0; scale range; 0–12). The prevalence of SHCs was highest in the severity of SCI group C1–4 AIS A, B, and C (mean; 8.9; scale range; 0–16). Conclusions Further research on geriatrics in SCI, non-traumatic SCI, and knowledge of the needs of persons with cervical lesion AIS A, B, or C is required, due to the fact that the prevalence of multimorbidity is high in these groups.

Abstract
STUDY DESIGN Prospective, observational study. OBJECTIVES The International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) represent the gold standard for the assessment of patients with spinal cord injury (SCI) and their measurement properties have been evaluated in patients with traumatic lesions. Albeit the ISNCSCI are widely used also for the assessment and prognosis of patients with non-traumatic SCI, a validation of this grading system in this sample has never been performed. Therefore, the aim of this study is to evaluate the measurement properties of the ISNCSCI in a population of persons with non-traumatic SCI. SETTING Three Italian rehabilitation hospitals. METHODS The sample included 140 patients with non-traumatic SCI of different etiology, level and grade, for a total of 169 evaluations performed by two examiners. Cronbach's Alpha was used to evaluate the internal consistency of the ISNCSCI various components. The agreement between two examiners of each center in the definition of different components was used to assess the inter-rater reliability. The construct validity was evaluated through the correlation of the ISNCSCI with the Spinal Cord Independence Measure (SCIM). RESULTS The ISNCSCI showed substantial internal consistency, and substantial inter-rater agreement for AIS grade, cumulative motor and sensory scores. The motor scores for upper and lower extremity showed fair to moderate correlation with SCIM self-care and motility subscores, respectively. The ISNCSCI total motor score correlated with the total SCIM score. CONCLUSIONS Our study demonstrates that the ISNCSCI are a valid and reliable tool for the assessment of patients with non-traumatic SCI.
