Trends in the characteristics and outcomes of older patients with non-traumatic spinal cord injury treated in inpatient rehabilitation facilities: 2013–2018

Objective To describe the characteristics and outcomes of older (≥ 65 years of age) patients with a non-traumatic spinal cord injury (NTSCI) treated in inpatient rehabilitation facilities (IRFs) between 2013 and 2018. Design Observational study. Setting IRFs in the United States. Participants 93,631 IRF Medicare stays for patients with NTSCI. Interventions Not Applicable. Main Outcome Measures Length of stay, self-care and mobility function, discharge destination. Results Between 2013 and 2018, the number of older (≥ 65 years of age) Medicare patients with a NTSCI treated in IRFs increased about 22.1 percent, from 14,149 to 17,275. In addition to the increase, patients’ sociodemographic characteristics shifted to have a slightly higher percentage of patients aged 65–74 years, a slightly higher percentage of males, and slightly fewer patients who identified as Hispanic. There was also a trend of more patients in the higher acuity case-mix groups and comorbidities tiers, but the median length of stay remained 12 days across all years. The percent of patients discharged home or to a community-based setting varied from 73.7 to 75.2 without a trend, although discharge self-care and mobility function increased slightly across the years. Conclusions Between 2013 and 2018, the number of Medicare patients with NTSCI treated in IRFs increased by more than 22 percent. While patient complexity increased, the median length of stay remained 12 days across the years. Discharge self-care and mobility function increased slightly, and the percent of patients discharged home ranged from 73.7 to 75.2 across the years.

Causes of Traumatic Spinal Cord Injury with Gender Distribution and Most Commonly Affected Age Group

Background: Spinal cord injury (SCI) has significant consequences, especially for young adults, requiring comprehensive support. Additionally, non-traumatic SCI is under-researched in Pakistan, highlighting the need for further investigation. Managing readmissions post-discharge remains a global challenge for SCI patients. This study conducted at Paraplegic Centre Peshawar aims to find the traumatic causes of spinal cord injury with gender and age distribution. Methods: A retrospective study was conducted at Paraplegic Center in Hayatabad and Prime Teaching Hospital, Peshawar. Over two months, 1843 patients were recruited from hospital records with permission from the department head. Data collection forms were designed to include age, gender, and cause of SCI, ensuring confidentiality by excluding personal identifiers. SPSS-V19 was used for data analysis. Results: Our study included 1843 patient records, with males comprising 80.7% and females 19.3%. Among different age groups, individuals aged 30 and older represented the highest proportion at 52.7%. The primary causes of spinal cord injury were falls from height (46.3%) and firearm injuries (25.9%). Paraplegic injuries were more prevalent, accounting for 87.9% of cases compared to quadriplegic injuries at 12.1%. These findings shed light on the demographics and patterns of spinal cord injuries, providing valuable insights for healthcare management and prevention strategies. Conclusion: Falls are major cause of spinal cord injury (SCI). Mean age patients suffers are 26. frequency of SCI is more in males then females. Paraplegia is more common then quadriplegia. The socioeconomic impact of SCI is eminence because it is affecting the youth population. It is important to understand the epidemiological features of SCIs which could lead to plan appropriate cost-effective prevention strategy in order to reduce the SCI prevalence and incidence in our community. 

A Systematic Review: Exercise Based Approaches to Activate Central Pattern Generator in Spinal Cord Injury Survivors

<i>Background: </i>Locomotion is a basic motor act which is essential for the survival of humans. The basic muscle synergies which are responsible for body propulsion are generated by the neurons in spinal cord collectively known as Central Pattern Generator for Locomotion. Spinal Cord is the major conduit for the transmission of information between brain and the rest of the body. Injury to the spinal cord is the insult to the neural elements of the spinal canal from foramen magnum to cauda equina. SCIs are heterogeneous in casualty, severity and location of injury but locomotion is the ultimate goal for the post-SCI survivors. In order for locomotion to occur, a complex CPG center of locomotion activation is required. Exercise based approach is the cornerstone in the treatment and management of individuals with SCI.<i> Objective</i>: To study the existing evidence on the effectiveness of Exercise-based approaches to activate Central Pattern Generator in Spinal Cord Injury Survivors with a focus on randomized controlled trials and cross over trials studies. <i>Methodology</i>: Literature published in English language. Original publications including RCTs and cross over trials published in peer-reviewed journals focused on traumatic or non-traumatic spinal cord injury published from 2014 to 2022. A key literature search adopted, for a more targeted search the following terms were used: effect of exercise, task-based approaches, body weight supported treadmill training, over ground training, balance and coordination training on the activation. <i>Search Strategy</i>: Database used were PubMed, Cochrane, Scopus, EMBASE, CINAHL and Medline. <i>Results</i>: Assessment of Risk of Bias was done using PeDro analysis. Eleven studies met the inclusion criteria out of 300 studies searched. <i>Discussion</i>: Exercise based approaches are highly essential and integrated part of the rehabilitation of spinal cord injury survivors. It has been concluded that activity-based therapies are highly effective but under-utilized by the rehabilitation specialists.

Reciprocal association between pain and quality of life after newly acquired spinal cord injury.

Pain is highly prevalent in spinal cord injury (SCI) and a key determinant of quality of life (QoL). This is the first study to examine reciprocal associations between pain and QoL in patients undergoing their first inpatient rehabilitation after SCI. Longitudinal data, with three measurement time points (1month and 3months after SCI onset, and at discharge from inpatient rehabilitation) from the Inception Cohort of the Swiss Spinal Cord Injury Cohort Study. Participants were 381 individuals aged ≥ 16years with a newly diagnosed traumatic or non-traumatic SCI. 75.1% were male and the average age was 53.2years. Random intercept cross-lagged panel models were conducted to examine the reciprocal association between pain intensity and QoL, as measured with the International SCI QoL Basic Data Set three individual items (satisfaction with life, physical health, and psychological health) and total score (mean of the three individual items). Both item and total QoL scores increased over time. 1month: 5.3 (SD = 2.7), 3months: 5.9 (SD = 2.3), discharge: 6.6 (SD = 2.0). Participants reported relatively low levels of pain intensity that remained stable over the course of inpatient rehabilitation. 1month: 2.7 (SD = 2.3), 3months: 2.6 (SD = 2.4), discharge: 2.7 (SD = 2.5). There were no significant cross-lagged associations between QoL and pain intensity across time. Results indicate that pain intensity does not predict changes in QoL during first rehabilitation, and vice versa. Associations between pain intensity and QoL reported by previous studies may be attributable to individual characteristics and timely events that simultaneously influence pain and QoL.

Role of Rehabilitation in Spine Tumors.

Primary and metastatic spine tumors can lead to devastating complications, but timely and careful management of these patients can improve outcomes. A multidisciplinary and structured approach is the most effective way to evaluate patients with spine disease and mitigate the risk of complications. The neurologic, oncologic, mechanical and systemic disease framework gives comprehensive guidance to providers regarding appropriate management. Physiatrists play a critical role in these patients' initial evaluation and continued management throughout cancer treatment. Patients with spinal cord involvement have extensive needs, requiring an individualized management approach. Even though patients with nontraumatic spinal cord injury benefit from rehabilitation efforts and have improved outcomes, they are not routinely admitted to inpatient rehabilitation units or referred to outpatient cancer rehabilitation. Ongoing efforts are needed to promote rehabilitation medicine involvement in improving functional outcomes and quality of life for patients with spine involvement.

A database of the healthy human spinal cord morphometry in the PAM50 template space

Abstract Measures of spinal cord morphometry computed from magnetic resonance images serve as relevant prognostic biomarkers for a range of spinal cord pathologies, including traumatic and non-traumatic spinal cord injury and neurodegenerative diseases. However, interpreting these imaging biomarkers is difficult due to considerable intra- and inter-subject variability. Yet, there is no clear consensus on a normalization method that would help reduce this variability and more insights into the distribution of these morphometrics are needed. In this study, we computed a database of normative values for six commonly used measures of spinal cord morphometry: cross-sectional area, anteroposterior diameter, transverse diameter, compression ratio, eccentricity, and solidity. Normative values were computed from a large open-access dataset of healthy adult volunteers (N = 203) and were brought to the common space of the PAM50 spinal cord template using a newly proposed normalization method based on linear interpolation. Compared to traditional image-based registration, the proposed normalization approach does not involve image transformations and, therefore, does not introduce distortions of spinal cord anatomy. This is a crucial consideration in preserving the integrity of the spinal cord anatomy in conditions such as spinal cord injury. This new morphometric database allows researchers to normalize based on sex and age, thereby minimizing inter-subject variability associated with demographic and biological factors. The proposed methodology is open-source and accessible through the Spinal Cord Toolbox (SCT) v6.0 and higher.

Convergent validity and responsiveness of The Standing and Walking Assessment Tool (SWAT) among individuals with non-traumatic spinal cord injury.

This study aimed to (1) describe the use of the Standing and Walking Assessment Tool (SWAT) among individuals with non-traumatic spinal cord injury or disease (NT-SCI/D); (2) evaluate the convergent validity of SWAT for use among inpatients with NT-SCI/D; (3) describe SWAT responsiveness; and (4) explore the relationship between hours of walking therapy and SWAT change. A quality improvement project was conducted at the University Health Network between 2019 and 2022. Participants' demographics and impairments data, rehabilitation length of stay, and FIM scores were obtained from the National Rehabilitation Reporting System. The walking measure data were collected by therapists as part of routine practice. Hours of part- or whole-gait practice were abstracted from medical records. To determine convergent validity, Spearman's correlation coefficients were calculated between SWAT stages (admission and discharge) and the walking measures. The change in SWAT levels was calculated to determine responsiveness. Spearman's correlation coefficient was calculated between SWAT change and hours of walking therapy. Among adult NT-SCI/D participants with potential walking capacity (SWAT≥1B), the majority were classified as American Spinal Injury Association (ASIA) Impairment Scale D (AIS D) at admission. The SWAT category of 1C (N = 100, 18%) was the most frequent at admission. The most frequent SWAT stage at discharge was 3C among participants with NT-SCI/D, with positive conversions in SWAT stages from admission to discharge (N = 276, 33%). The mean change in SWAT score was 3 for participants with T-SCI and NT-SCI/D. Moderate correlations between SWAT stages and walking measures were observed. The correlation of hours of gait therapy with the SWAT change (admission to discharge) was 0.44 (p < 0001). The SWAT has sufficient convergent validity and responsiveness for describing standing and walking recovery and communicating/monitoring rehabilitation progress among patients with NT-SCI/D.

Epidemiology features of traumatic and non-traumatic spinal cord injury in China, Wuhan

Spinal cord injuries are incredibly disabling and can have fatal consequences. At present, there is a lack of available information regarding the epidemiological characteristics of patients who have experienced spinal cord injury (SCI) in China. This retrospective hospital-based study was conducted in the Rehabilitation department of Wuhan’s Tongji Hospital between 2016 and 2022. A total of 649 individuals diagnosed with SCI (both traumatic and non-traumatic) were admitted during this period. Data regarding various epidemiological features were gathered, including sex, age, etiology, occupation, neurological level of injury, the American Spinal Injury Association Impairment Scale at the time of admission, and information on any accompanying injuries. Out of the 649 cases of SCI, there were 539 cases of traumatic SCI and 110 cases of non-traumatic SCI. The mean age at the time of injury was 45.6 ± 14.8 years. The ratio of male to female patients was higher in traumatic SCI at 2.82:1compared to non-traumatic SCI at 1.68:1. Traffic accidents were the most common cause of TSCI, accounting for (n = 207/539; 38.40%) of cases. On the other hand, neoplasm was the most common cause of NTSCI, accounting for (n = 38/110; 34.54%) of cases. The findings indicated a higher proportion of males, with traffic accidents being the main cause of injury among TSCI patients. It is crucial to prioritize the risk of falling among older adults and allocate more attention to this issue. These results emphasize the need for tailored preventive strategies that consider the unique characteristics of different types of SCI patients.

Network analysis of multimorbidity and health outcomes among persons with spinal cord injury in Canada.

Multimorbidity, defined as the coexistence of two or more health conditions, is common in persons with spinal cord injury (SCI). Network analysis is a powerful tool to visualize and examine the relationship within complex systems. We utilized network analysis to explore the relationship between 30 secondary health conditions (SHCs) and health outcomes in persons with traumatic (TSCI) and non-traumatic SCI (NTSCI). The study objectives were to (1) apply network models to the 2011-2012 Canadian SCI Community Survey dataset to identify key variables linking the SHCs measured by the Multimorbidity Index-30 (MMI-30) to healthcare utilization (HCU), health status, and quality of life (QoL), (2) create a short form of the MMI-30 based on network analysis, and (3) compare the network-derived MMI to the MMI-30 in persons with TSCI and NTSCI. Three network models (Gaussian Graphical, Ising, and Mixed Graphical) were created and analyzed using standard network measures (e.g., network centrality). Data analyzed included demographic and injury variables (e.g., age, sex, region of residence, date, injury severity), multimorbidity (using MMI-30), HCU (using the 7-item HCU questionnaire and classified as "felt needed care was not received" [HCU-FNCNR]), health status (using the 12-item Short Form survey [SF-12] Physical and Mental Component Summary [PCS-12 and MCS-12] score), and QoL (using the 11-item Life Satisfaction questionnaire [LiSAT-11] first question and a single item QoL measure). Network analysis of 1,549 participants (TSCI: 1137 and NTSCI: 412) revealed strong connections between the independent nodes (30 SHCs) and the dependent nodes (HCU-FNCNR, PCS-12, MCS-12, LiSAT-11, and the QoL score). Additionally, network models identified that cancer, deep vein thrombosis/pulmonary embolism, diabetes, high blood pressure, and liver disease were isolated. Logistic regression analysis indicated the network-derived MMI-25 correlated with all health outcome measures (p <0.001) and was comparable to the MMI-30. The network-derived MMI-25 was comparable to the MMI-30 and was associated with inadequate HCU, lower health status, and poor QoL. The MMI-25 shows promise as a follow-up screening tool to identify persons living with SCI at risk of having poor health outcomes.

Exploring the Lived Experiences of Individuals With Spinal Cord Injury During the COVID-19 Pandemic.

The global spread of severe acute respiratory syndrome coronavirus 2019 (COVID-19) has affected over 100 countries and has led to the tragic loss of life, overwhelmed health care systems and severely impacted the global economy. Specifically, individuals living with spinal cord injury (SCI) are particularly vulnerable during the COVID-19 pandemic as they often face adverse impacts on their health, emotional well-being, community participation, and life expectancy. The objective of this study was to investigate the lived experience of individuals with SCI during the COVID-19 pandemic in Ontario, Canada. An exploratory design with a qualitative descriptive approach was used to address the study objective. Nine semi-structured interviews were conducted with individuals with traumatic and non-traumatic SCI (37-69 years, C3-L5, AIS A-D, and 5-42 years post-injury). Using reflexive thematic analysis, the following themes were created: (1) Caregiver exposure to COVID-19; (2) Staying physically active in quarantine; (3) Living in social isolation; (4) Difficulty obtaining necessary medical supplies; (5) Access to health services and virtual care during COVID-19; and (6) Fighting COVID-19 misinformation. This is one of the first studies to explore the impact of COVID-19 on individuals living with SCI in Ontario. This study contributes to a greater understanding of the challenges faced by individuals living with SCI and provides insight into how to better support and respond to the specific and unique needs of individuals with SCI and their families during a national emergency or pandemic.

“I am just trying to live a life!” –a qualitative study of the lived experience of pressure ulcers in people with spinal cord injuries

BackgroundPressure ulcers (PUs) are frequently reported in people with spinal cord injuries (SCI). Wound management in people with SCI involves relieving pressure on the affected area by means of immobilisation and bed rest. The healing time of a PU can vary, but often takes several months or even years, causing people to stay in bed for prolonged periods of time. Objective: This study aims to explore the perspectives and lived experiences of people with SCI who are affected by PUs. Designand method: This study is a qualitative explorative study that employs individual semi-structured in-depth interviews to obtain the narratives of people with SCI and a pressure ulcer. We used a phenomenological-hermeneutic approach that was inspired by Ricoeur's theory of interpretation. The analysis was performed in three levels: Naïve reading, structural analysis and critical interpretation and discussion. Participantsand setting: Ten people with SCI who were being treated in the Danish healthcare system for their PU participated in this study: six participants had experienced a complete traumatic SCI, three had an incomplete traumatic SCI, and one had a non-traumatic complete SCI. The study included nine men and one woman, aged 49–81 years (mean 64). Nine had a PU in the seating area, while one had the ulcer on the leg. ResultsThe analysis revealed three themes: 1. Struggling to balance prevention with an active, meaningful life, 2. Challenges and consequences of pressure relief protocols and bed rest, 3. Experiencing prolonged and incoherent treatment with varying levels of staff engagement and competencies. ConclusionsPeople with SCI and a PU have difficulty balancing their active, redefined lives when subjected to a strict pressure relief protocol. The consequences of immobility caused by pressure relief include reduced social and community participation and decreased quality of life. PU treatment is experienced as incoherent and unnecessarily lengthy, leading to a deterioration in the wounds. Improving PU treatment for people with SCI is of utmost importance and has the potential to benefit not only the people with SCI but also the healthcare system and the economy.

Factors associated with urinary tract infection in the early phase after performing intermittent catheterization in individuals with spinal cord injury: a retrospective study.

To investigate the occurrence rate of urinary tract infections (UTIs) in the early phase after performing intermittent catheterization (IC) and to explore the possible factors associated with UTIs after performing IC among people with spinal cord injury (SCI). An inpatient rehabilitation department of a teaching hospital in China. Retrospective chart review. A retrospective chart review was carried out for traumatic and non-traumatic SCI patients after performing IC during their inpatient stay. Demographic information, comorbidity of diabetes, urine analysis results before IC, method of IC (sterile or clean), use of bladder irrigation, cessation of IC and its reasons, and UTI events were collected. A total of 183 adult individuals were included, of which 60 (32.8%) of them were women. The median age was 49.0 years. The median time post-injury was 2 months. The overall occurrence rate of UTI after performing IC was 1.31 (95% confidence intervals: 0.96-1.77) events per 100 days. Sixty-nine (37.7%) patients discontinued IC during hospitalization, and UTIs were the leading reason for cessation (50.7%). Female sex, use of antibiotics for infections other than UTI, and use of bladder irrigation were found to be associated with a lower occurrence rate of UTI in the early phase after performing IC, with an odds ratio of 0.38 (p = 0.019), 0.20 (p = 0.022), and 0.24 (p < 0.001), respectively. UTI after performing IC is prevalent among people with SCI. The study indicated that antibiotic prophylaxis and routine bladder irrigation might be associated with the reduction in UTI in the early phase after performing IC. Further research is needed to provide more evidence.

A Look at Spinal Cord Injury in Canada: Rick Hansen Spinal Cord Injury Registry (RHSCIR) - 2021 SCI Data Summary.

The Rick Hansen Spinal Cord Injury Registry (RHSCIR) is a prospective registry of individuals who sustain a spinal cord injury (SCI) from 18 acute and 14 rehabilitation (rehab) Canadian hospitals specializing in SCI care. The data summary provides demographic and clinical details on 1148 people with either a traumatic spinal cord injury (tSCI) or a nontraumatic spinal cord injury (ntSCI) who were treated at a RHSCIR hospital in 2021. Information about the patient demographics, cause and severity of injury, care pathway, length of hospital stay, secondary complications, and social impacts after SCI were included. Data from the summary can provide researchers, healthcare providers, and decision makers with knowledge and evidence that may support strategies to improve SCI care services within their institutions.

Increased cranio-caudal spinal cord oscillations are the cardinal pathophysiological change in degenerative cervical myelopathy.

Degenerative cervical myelopathy (DCM) is the most common cause of non-traumatic incomplete spinal cord injury, but its pathophysiology is poorly understood. As spinal cord compression observed in standard MRI often fails to explain a patient's status, new diagnostic techniques to assess DCM are one of the research priorities. Minor cardiac-related cranio-caudal oscillations of the cervical spinal cord are observed by phase-contrast MRI (PC-MRI) in healthy controls (HCs), while they become pathologically increased in patients suffering from degenerative cervical myelopathy. Whether transversal oscillations (i.e., anterior-posterior and right-left) also change in DCM patients is not known. We assessed spinal cord motion simultaneously in all three spatial directions (i.e., cranio-caudal, anterior-posterior, and right-left) using sagittal PC-MRI and compared physiological oscillations in 18 HCs to pathological changes in 72 DCM patients with spinal canal stenosis. The parameter of interest was the amplitude of the velocity signal (i.e., maximum positive to maximum negative peak) during the cardiac cycle. Most patients suffered from mild DCM (mJOA score 16 (14-18) points), and the majority (68.1%) presented with multisegmental stenosis. The spinal canal was considerably constricted in DCM patients in all segments compared to HCs. Under physiological conditions in HCs, the cervical spinal cord oscillates in the cranio-caudal and anterior-posterior directions, while right-left motion was marginal [e.g., segment C5 amplitudes: cranio-caudal: 0.40 (0.27-0.48) cm/s; anterior-posterior: 0.18 (0.16-0.29) cm/s; right-left: 0.10 (0.08-0.13) cm/s]. Compared to HCs, DCM patients presented with considerably increased cranio-caudal oscillations due to the cardinal pathophysiologic change in non-stenotic [e.g., segment C5 amplitudes: 0.79 (0.49-1.32) cm/s] and stenotic segments [.g., segment C5 amplitudes: 0.99 (0.69-1.42) cm/s]). In contrast, right-left [e.g., segment C5 amplitudes: non-stenotic segment: 0.20 (0.13-0.32) cm/s; stenotic segment: 0.11 (0.09-0.18) cm/s] and anterior-posterior oscillations [e.g., segment C5 amplitudes: non-stenotic segment: 0.26 (0.15-0.45) cm/s; stenotic segment: 0.11 (0.09-0.18) cm/s] remained on low magnitudes comparable to HCs. Increased cranio-caudal oscillations of the cervical cord are the cardinal pathophysiologic change and can be quantified using PC-MRI in DCM patients. This study addresses spinal cord oscillations as a relevant biomarker reflecting dynamic mechanical cord stress in DCM patients, potentially contributing to a loss of function.

Penggunaan Spinal Cord Independence Measure III sebagai Alat Ukur Kemampuan Fungsional Pasien Spinal Cord Injury di Indonesia

This study aims to determine the use of the Spinal Cord Independence Measure (SCIM) III as a functional measurement tool for spinal cord injury patients in Indonesia. The method used was cross-sectional as a pilot project. The population of this study were trauma and non-traumatic spinal cord injury patients. The results of this study indicate that SCIM III can assess the patient's functional status in self-care, bladder management, bowel management, and mobilization. In conclusion, SCIM III is an objective and reliable questionnaire that can be used as a tool to measure the functional ability of SCI patients. In addition, SCIM can be used to determine interventions that are appropriate to the patient's condition so that the outcome of the rehabilitation phase of care to make the patient independent can be achieved optimally.&#x0D;  &#x0D; Keywords: Tool, Functional, Spinal Cord Independence Measure

Toward Shared Decision-Making in Degenerative Cervical Myelopathy: Protocol for a Mixed Methods Study.

Health care decisions are a critical determinant in the evolution of chronic illness. In shared decision-making (SDM), patients and clinicians work collaboratively to reach evidence-based health decisions that align with individual circumstances, values, and preferences. This personalized approach to clinical care likely has substantial benefits in the oversight of degenerative cervical myelopathy (DCM), a type of nontraumatic spinal cord injury. Its chronicity, heterogeneous clinical presentation, complex management, and variable disease course engenders an imperative for a patient-centric approach that accounts for each patient's unique needs and priorities. Inadequate patient knowledge about the condition and an incomplete understanding of the critical decision points that arise during the course of care currently hinder the fruitful participation of health care providers and patients in SDM. This study protocol presents the rationale for deploying SDM for DCM and delineates the groundwork required to achieve this. The study's primary outcome is the development of a comprehensive checklist to be implemented upon diagnosis that provides patients with essential information necessary to support their informed decision-making. This is known as a core information set (CIS). The secondary outcome is the creation of a detailed process map that provides a diagrammatic representation of the global care workflows and cognitive processes involved in DCM care. Characterizing the critical decision points along a patient's journey will allow for an effective exploration of SDM tools for routine clinical practice to enhance patient-centered care and improve clinical outcomes. Both CISs and process maps are coproduced iteratively through a collaborative process involving the input and consensus of key stakeholders. This will be facilitated by Myelopathy.org, a global DCM charity, through its Research Objectives and Common Data Elements for Degenerative Cervical Myelopathy community. To develop the CIS, a 3-round, web-based Delphi process will be used, starting with a baseline list of information items derived from a recent scoping review of educational materials in DCM, patient interviews, and a qualitative survey of professionals. A priori criteria for achieving consensus are specified. The process map will be developed iteratively using semistructured interviews with patients and professionals and validated by key stakeholders. Recruitment for the Delphi consensus study began in April 2023. The pilot-testing of process map interview participants started simultaneously, with the formulation of an initial baseline map underway. This protocol marks the first attempt to provide a starting point for investigating SDM in DCM. The primary work centers on developing an educational tool for use in diagnosis to enable enhanced onward decision-making. The wider objective is to aid stakeholders in developing SDM tools by identifying critical decision junctures in DCM care. Through these approaches, we aim to provide an exhaustive launchpad for formulating SDM tools in the wider DCM community. DERR1-10.2196/46809.

Predictive value of intraoperative contrast-enhanced ultrasound in functional recovery of non-traumatic cervical spinal cord injury.

To evaluate the ability of intraoperative CEUS to predict neurological recovery in patients with degenerative cervical myelopathy (DCM). Twenty-six patients with DCM who underwent laminoplasty and intraoperative ultrasound (IOUS) were included in this prospective study. The modified Japanese Orthopaedic Association (mJOA) scores and MRI were assessed before surgery and 12months postoperatively. The anteroposterior diameter (APD), maximum spinal cord compression (MSCC), and area of signal changes in the cord at the compressed and normal levels were measured and compared using MRI and IOUS. Conventional blood flow and CEUS indices (time to peak, ascending slope, peak intensity (PI), and area under the curve (AUC)) at different levels during IOUS were calculated and analysed. Correlations between all indicators and the neurological recovery rate were evaluated. All patients underwent IOUS and intraoperative CEUS, and the total recovery rate was 50.7 ± 33.3%. APD and MSCC improved significantly (p < 0.01). The recovery rate of the hyperechoic lesion group was significantly worse than that of the isoechoic group (p = 0.016). 22 patients were analysed by contrast analysis software. PI was higher in the compressed zone than in the normal zone (24.58 ± 3.19 versus 22.43 ± 2.39, p = 0.019). ΔPI compress-normal and ΔAUC compress-normal of the hyperechoic lesion group were significantly higher than those of the isoechoic group (median 2.19 versus 0.55, p = 0.017; 135.7 versus 21.54, p = 0.014, respectively), and both indices were moderately negatively correlated with the recovery rate (r =  - 0.463, p = 0.030; r =  - 0.466, p = 0.029). Signal changes and microvascular perfusion evaluated using CEUS during surgery are valuable predictors of cervical myelopathy prognosis. In the spinal cord compression area of degenerative cervical myelopathy, especially in the hyperechoic lesions, intraoperative CEUS showed more significant contrast agent perfusion than in the normal area, and the degree was negatively correlated with the neurological prognosis. • Recovery rates in patients with hyperechoic findings were lower than those of patients without lesions detected during intraoperative ultrasound. • The peak intensity of CEUS was higher in compressed zones than in the normal parts of the spinal cord. • Quantitative CEUS comparisons of the peak intensity and area under the curve at the compressed and normal levels of the spinal cord revealed differences that were inversely correlated to the recovery rate.

A review of neurological health disparities in Peru.

Peru is a historically unique and culturally diverse Latin American country. As a low-to-middle-income country (LMIC), Peru faces health implications from the spread of communicable diseases as well as a growing rate of noncommunicable diseases, both of which have been worsened by the recent COVID-19 pandemic's impact on the national health system. Over the past two decades, the country has aimed to improve health access for its population through various efforts described in this review. Despite this, there are notable neurological health disparities that exist today. This narrative review investigates such disparities through the leading neurological contributors to the national burden of disease in the country, including migraine headaches, cerebrovascular disease, and dementia. Public health disparities that contribute to other major neurological diseases in the country, including epilepsy, neurocysticercosis, Chagas disease, multiple sclerosis, traumatic brain injury, traumatic and non-traumatic spinal cord injuries are also investigated. We also explore potential solutions for overcoming the various neurological health disparities covered in this review that may be applied through public policies, as well as in similar LMICs in Latin America. By overcoming such disparities, the country may be able to successfully address the major contributors of neurological disease burden and create a healthcare environment that can sustainably and equitably improve health outcomes for Peruvian people.
