ABSTRACT

Objective:To investigate the application effect of discharge preparation service based on theory of goal attainment on patients with cervical spinal cord injury.Methods:A retrospective cohort study was conducted to analyze the clinic data of 60 patients with cervical spinal cord injury admitted to Zhengzhou Orthopedics Hospital from January 2017 to December 2022, including 49 males and 11 females, aged 23-79 years [(52.2±13.5)years]. Patients were all treated with cervical decompression fusion and internal fixation. Patients admitted from January 2017 to December 2019 were treated with conventional nursing intervention (conventional nursing group, n=30) and patients admitted from January 2020 to December 2022 were treated with discharge preparation service based on theory of goal attainment (discharge preparation service group, n=30). The readiness for hospital discharge of the two groups was compared using the Chinese version of Readiness for Hospital Discharge Scale (RHDS) at 4 hours before discharge. The degree of cervical spinal cord dysfunction of the two groups were compared using Japanese Orthopedic Association (JOA) score before intervention, at discharge and at 6 months after discharge. The complication and unplanned readmission rates of the two groups were compared at 6 months after discharge. Results:All the patients were followed up for 6 months. At 4 hours before discharge, the scores of the three parameters of RHDS containing personal status, adaptability and anticipatory support and the total score of the discharge preparation service group were (20.9±3.5)points, (35.9±2.2)points, (30.4±3.0)points and (87.1±7.8)points respectively, higher than those of the conventional nursing group [(16.2±1.7)points, (32.5±2.2)points, (26.3±2.1)points and (75.0±5.6)points respectively] ( P<0.01). There was no statistically significant difference in the JOA score of the two groups before intervention ( P>0.05). The JOA scores of the discharge preparation service group at discharge and at 6 months after discharge were (11.8±1.7)points and (13.8±1.5)points respectively, higher than those of the conventional nursing group [(10.3±1.8)points and (11.6±1.9)points respectively] ( P<0.01). At 6 months after discharge, the complication rate of the discharge preparation service group was 6.7% (2/30), lower than that of the conventional nursing group [36.7% (11/30)] ( P<0.05). The unplanned readmission rate of the discharge preparation service group was 3.3% (1/30), lower than that of the conventional nursing group [23.3% (7/30)] ( P<0.05). Conclusion:For patients with cervical spinal cord injury, discharge preparation service based on theory of goal attainment can improve the discharge readiness, promote spinal functional recovery and reduce the complication and unplanned readmission rates.

ABSTRACT

Resumo Objetivo Identificar o conflito de decisão de pacientes com lesão medular frente ao cateterismo intermitente limpo. Métodos Estudo observacional, transversal, e quantitativo, que utilizou duas ferramentas de pesquisa, um questionário sociodemográfico e clínico e a versão brasileira da Decisional Conflict Scale. A investigação foi empreendida com uma amostra não probabilística em um hospital público especializado em reabilitação no Distrito Federal. Os dados coletados foram analisados por meio de estatística inferencial e descritiva de tendência central e de dispersão utilizando-se frequências absoluta e relativa, média e desvio padrão. O protocolo de pesquisa foi avaliado e aprovado pelo Comitê de Ética em Pesquisa da Secretaria de Saúde do Distrito Federal e todos os participantes aderiram ao termo de consentimento livre e esclarecido. Resultados A pesquisa envolveu 30 pacientes, sendo a maioria homens, com idade média de 32,43 anos. Destes 16 realizavam o auto cateterismo e 14 eram submetidos ao cateterismo assistido. O conflito de decisão foi identificado em metade dos pacientes, predominantemente entre os com menor tempo de lesão medular e período de realização do cateterismo. A lacuna de informações e a falta de suporte para a realização do procedimento foram os fatores preponderantes para a ocorrência do conflito de decisão. Conclusão O tempo de lesão e de realização do cateterismo parecem influenciar na aquisição de habilidades e conhecimentos na realização do cateterismo, manifestando-se com acentuado conflito decisório logo após a lesão. Suporte decisional e autocuidado apoiado podem contribuir para melhor engajamento do paciente.


Resumen Objetivo Identificar los conflictos de decisión de pacientes con lesión medular respecto al cateterismo intermitente limpio. Métodos Estudio observacional, transversal y cuantitativo, en el que se utilizaron dos herramientas de investigación, un cuestionario sociodemográfico y clínico y la versión brasileña de la Decisional Conflict Scale. La investigación se llevó a cabo con una muestra no probabilística en un hospital público especializado en rehabilitación en el Distrito Federal. Los datos recopilados se analizaron mediante estadística inferencial y descriptiva de tendencia central y de dispersión, con el uso de frecuencia absoluta y relativa, promedio y desviación típica. El protocolo de investigación fue evaluado por el Comité de Ética en Investigación de la Secretaría de Salud del Distrito Federal y todos los participantes adhirieron al consentimiento informado. Resultados Participaron 30 pacientes en el estudio, la mayoría hombres, de 32,43 años de edad promedio. Del total, 16 realizaban el autocateterismo y 14 el cateterismo asistido. Se identificaron conflictos de decisión en la mitad de los pacientes, de forma predominante en aquellos con menor tiempo de lesión medular y período de realización del cateterismo. El vacío de información y la falta de apoyo para la realización del procedimiento fueron los factores preponderantes para los casos de conflicto de decisión. Conclusión El tiempo de lesión y de realización del cateterismo parecen influir en la adquisición de habilidades y conocimientos para la realización del cateterismo, y se manifiesta con un elevado conflicto decisorio poco después de la lesión. El apoyo en la decisión y el autocuidado con apoyo pueden contribuir para que el paciente se comprometa más.


Abstract Objective To identify the decisional conflict of patients with spinal cord injury who perform clean intermittent catheterization. Methods An observational, cross-sectional, quantitative study was conducted using two research tools: a sociodemographic/clinical questionnaire and the Brazilian version of the Decisional Conflict Scale. The research was carried out with a non-probabilistic sample in a public hospital specializing in rehabilitation in the Federal District. The data collected was analyzed using inferential and descriptive statistics of central tendency and dispersion using absolute and relative frequencies, mean, and standard deviation. The research protocol was evaluated and approved by the Research Ethics Committee of the Federal District Health Secretariat and all participants signed an informed consent form. Results The study involved 30 patients, most of whom were men, with a mean age of 32.43 years. Of these, 16 performed self-catheterization and 14 underwent assisted catheterization. Conflict of decision was identified in half of the patients, predominantly among those with a shorter period of spinal cord injury and period of catheterization. The information gap and the lack of support for the procedure were the main factors in decisional conflicts. Conclusion The time since the injury and the period during which the catheterization was performed seem to influence the acquisition of skills and knowledge in performing the procedure, showing a marked decisional conflict soon after the injury. Decisional support and supported self-care can contribute to better patient engagement.

ABSTRACT

ABSTRACT Objective: Analyze the effects of high-intensity interval training (HIIT) on cardiometabolic parameters, and cardiorespiratory fitness to compile the most used HIIT training types in adults with spinal cord injury (SCI). Methods: This is a systematic review of searches performed in the electronic databases PubMed / Medline, Science Direct, and Google Scholar. Studies included I) needed to apply HIIT training II) adults with SCI to analyze III) cardiometabolic aspects and cardiorespiratory fitness. Two independent reviewers selected the articles for inclusion, extracted their data, and assessed their methodological quality. Results: 654 studies were found. Thus, 12 studies, 11 pre- and post-intervention, and one control group (CG) with 106 participants were analyzed. Pre- and post-HIITT intervention results revealed significant improvement in cardiorespiratory fitness and cardiometabolic aspects (VO2peak, LDH, HDL, insulin resistance). In addition, GC results revealed significant improvement in cardiorespiratory fitness observed in the intervention group (HIIT) compared to the moderate-low intensity (GC) group. Seven studies used the arm ergometer as the primary exercise modality. Two studies described functional electrical stimulation (FES) performed with the arm ergometer plus electrical stimulation in the lower limbs. None reported heart rate dynamics during the study period. Conclusion: High-intensity interval training improves physical fitness and cardiometabolic health in adults with SCI. Evidence level II; Systematic Review of level II studies.

This calls for an evaluation of the long-term influence of the use of a device specially developed for orthostatic posture on the physiological, biomechanical and functional parameters of amputees and spinal cord patients. Objective: The objective was evaluate the effect of postural support device use on function, pain, and biomechanical and cardiologic parameters in spinal cord injury and amputees patients compared to a control group. Methods: The orthostatic device was used by the participants for a period of ten consecutive days, for three cycles of 50 minutes each day, and a 15-day follow-up. Participants were positioned and stabilized using adjustable straps on the shoulders, trunk, and hips. The primary outcome was brief pain inventory. Fifteen participants were included the control group, 15 in the amputee group, and 15 in the spinal cord group. Results: Our results demonstrate that the use of the device allows the orthostatic position of amputees and spinal cord patients evaluated for ten days, leading to improved functionality and pain in the spinal cord and amputee groups compared to the control group. In addition, no changes were observed for secondary outcomes, indicating that the use of the device did not cause harm interference to patients. Conclusion: The long-term use of the orthostatic device is beneficial for improving functionality, reduce pain in amputees and spinal cord injury patients.

ABSTRACT

Abstract Objective The aim of this study was to evaluate the GSH effect on functional and histological recovery after experimental spinal cord injury in rats. Methods Forty Wistar rats were subjected to spinal cord injury through the Multicenter Animal Spinal Cord Injury Study (MASCIS) Impactor system. The rats were sorted and divided into four groups, as follows: Group 1 ‒ Laminectomy and spinal cord injury; Group 2 ‒ Laminectomy, spinal cord injury and Saline Solution (SS) 0.9%; Group 3 ‒ Laminectomy, spinal cord injury, and GSH; and Group 4 ‒ lLaminectomy without spinal cord injury. GSH and SS were administered intraperitoneally. Groups 1 and 4 received no intervention. Results The rats were evaluated for locomotor function recovery at seven different times by the Basso, Beattie, and Bresnahan (BBB) scale on days 2, 7, 14, 21, 28, 35, and 42 after the spinal cord injury. On day 42, the rats were sacrificed to analyze the histological findings of the injured spinal cord. In the group submitted to GSH, our experimental study revealed better functional scores on the BBB scale, horizontal ladder scale, and cranial and caudal axon count. The differences found were statistically significant in BBB scores and axonal count analysis. Conclusion This study demonstrated that using glutathione in experimental spinal trauma can lead to better functional recovery and improved axonal regeneration rate in Wistar rats submitted to experimental spinal cord injury.

ABSTRACT

Objectives: To determine the prevalence of individuals with a traumatic spinal cord injury in Nairobi, Kenya. Methods: Retrospective quantitative data was extracted from records of 1st January 2010 to December 2014, at the NSIH. (N=320) participants met the inclusion criteria of all TSCI patients injured archived medical files, out these (n=217) were men, and (n=103) women, collected data was analyzed by SPSS version 23.0. Pearson chi-square was applied to test for association between variables, Student t-test was used to compare mean difference between groups, study Significance level was at p-value <0.05.Results: Mean age of the participants was 37.59 (SD= 15.038), the highest percentage age was 30-39 years old at (27.8%) followed aged 18-29 years at (26.6%). Male to female ratio was 2.1:1, highest prevalence occurred in 2010 and 2014 (20.5%), main cause of a TSCI transportation (49.1%), fall at (33.4%), assault (17.5%) common injury location was at lumber (53.1%), followed thoracic at (27.5%) cervical and sacral at (19.1%) and (0.3%) respectively. There were significantly more persons with paraplegia (54.1%) who had complete injuries than those with tetraplegia (19.6%). Other (27.3%) accounted for the TSCI patients with incomplete paraplegia and tetraplegia and no neurological deficits Conclusions: TSCI is a devastating condition to individuals; it has a high impact on QOL and ADL in low-income countries where there is an increase in manual labor and poor infrastructure, which predispose individuals to TSCI. Further studies need to be done to understand and compare epidemiological results, to inform appropriate prevention strategies that will decrease the burden of TSCI globally.

ABSTRACT

Recentemente, a terapia por ondas de choque extracorpóreas (TOCE) mostraram-se ser uma promissora tecnologia não invasiva para neuromodulação e recuperação funcional devido a melhora em brotamento neuronal, neuroproteção, controle de neuroplasticidade e reorganização neuronal, além de atuar em fatores de neurogênese. Objetivo: Descrever um caso que usa TOCE como um adjuvante na reabilitação de trauma medular. Relato de caso: LPS, 25 anos, estudante de medicina, sofreu uma queda de altura indeterminada com fratura de C5 e lesão medular associada a trauma cranioencefálico. Na fase aguda, ele se recuperou adequadamente, tendo sido submetido a descompressão e fixação de coluna e hospitalizado por 5 meses devido a disautonomias e infecções urinárias. Após esse período, ele iniciou um programa de reabilitação intensiva para tetraplegia espástica com classificação inicial segundo o ASIA (American Spinal Injury Association) nível C5 motor e C6 sensório. O tratamento incluiu 10 sessões de TOCE, realizadas com Duolith SD1 (Storz Medical, Suíça) com uma densidade de energia de 0,25mJ/mm², 5 cm e 3 cm de profundidade de foco, 2000 pulsos aplicados na linha média de coluna níveis C5 a T1 e 2000 pulsos a 5 cm de profundidade aplicados em região plantar bilateral. Bloqueio com toxina botulínica e fenol foram realizados com resposta parcial apesar da dose otimizada de baclofeno.


Recently, extracorporeal shockwaves (ESWT) have shown as a promising non-invasive technology for neuromodulation and functional recovery, due to improving neuronal budding, neuroprotection, control of neuroplasticity and neuronal reorganization, in addition to acting on neurogenesis factors. Objective: To describe a case that uses ESWT as an adjuvant to the rehabilitation of spinal cord trauma. Case Report: LPS, 25 years old, medical student, suffered a fall from an undetermined height with C5 fracture and spinal cord injury, associated with a cranioencephalic trauma. In the acute phase, he was rescued properly, performed decompression and spinal cord fixation and remained hospitalized for 5 months due to dysautonomia and urinary infections. After this period, he started an intensive in-patient rehabilitation program for spastic tetraplegia with initial classification according to ASIA C5 (motor) and C6 (sensory). The treatment included 10 sessions of ESWT, made with Duolith SD1 (Storz Medical, Switzerland) with an Energy flux density 0,25 mJ/mm2, at 5cm and 3cm depth focus, 2000 pulses each over the spinal cord at the midline of levels from C5 to T1, and 2000 pulses at 5cm depth focus applied at plantar region bilaterally.

ABSTRACT

Objetivo : Determinar los factores condicionantes para la participación laboral de las personas con discapacidad por lesión medular de un instituto especializado de rehabilitación. Material y métodos : Estudio observacional, retrospectivo y relacional; se incluyeron 224 pacientes con lesión medular del Departamento de Investigación, Docencia, y Atención en Ayuda al Tratamiento del Servicio de Rehabilitación Profesional que fueron atendidos en el periodo 2016 al 2019. Se recolectaron variables clínicas, sociodemográficas y contextuales; y la actividad económica antes y después de la lesión. Resultados : El 65 % de pacientes fueron del sexo masculino, de edad media de 38,61 ± 13,33; según el nivel de lesión medular el 85,3% de pacientes tenía paraplejia, el 62,5% con grado de lesión en la escala ASIA A; el tiempo de evolución fue de más de 1 año 30,4%, estado civil soltero 52,2%, de procedencia Lima y provincias el 51,3%, con grado de instrucción de secundaria 50,9%, nivel socioeconómico de pobreza extrema en 61%. Se encontró diferencia significativa entre la participación laboral antes de la LM y el sexo (p<0,01) y la condición laboral (p<0,0069). La participación laboral después de la LM tuvo una diferencia significativa con el nivel socioeconómico (p<0.005) y el grado de lesión en la escala ASIA (p<0,014). El análisis de regresión logística mostró que el único factor asociado con la participación laboral fue el tiempo transcurrido de la lesión medular (p=0,039; OR=19,9). Conclusiones : Los pacientes con LM con menores ingresos económicos ubicados en grupos de pobreza pobre extremo y no extremo tuvieron mayor participación laboral; así como los que tuvieron un mayor grado de lesión en la escala ASIA. Asimismo, el único factor predictor de la participación laboral fue el tiempo transcurrido desde la lesión.


SUMMARY Objective : To determine the conditioning factors for labor participation in persons with disability due to spine lesions attended at a specialized rehabilitation center. Methods : A retrospective observational study was carried out at the Departamento de Investigación, Docencia, y Atención en Ayuda al Tratamiento del Servicio de Rehabilitación Profesional from 2016 to 2019, 224 patients were evaluated. Clinical, sociodemographic and contextual variables were collected as well as economic activity before and after the trauma. Results : 65% of patients were males; mean age was 38.61 ± 13.33; 85.3% had paraplegia and 63.5% had a lesion grade A on the ASIA scale; duration of illness was higher than one year in 30.4%; 52.2% were single; 51.3% come from provinces of Peru; 50.9% had secondary school level and 61% lived in extreme poverty. A significative difference for labor participation was found between sex (p<0.01) and labor condition (p<0.014) before the spinal lesion. Labor participation after the spinal lesion correlated with socioeconomic level (p<0.005) and the degree of the lesion based on the ASIA scale (p<0.014). The logistic regression analysis found that only duration of illness correlated with labor participation (p=0.039; OR=19.9). Conclusions : Patients with spinal lesions who lived in extreme poverty had higher labor participation as well as those with higher scores in the ASIA scale. The only predicting factor for labor participation was duration of illness.

ABSTRACT

Abstract Objective The objective of the present study was to evaluate the current practice in terms of timing to surgery in acute spinal cord injury (ASCI) patients among spinal surgeons from Iberolatinoamerican countries. Methods A descriptive cross-sectional study design as a questionnaire was sent by an email for all members of the Sociedad Ibero Latinoamericana de Columna (SILACO, in the Spanish acronym) and associated societies. Results A total of 162 surgeons answered questions related to the timing for surgery. Sixty-eight (42.0%) considered that ASCI with complete neurology injury should be treated within 12 hours, 54(33.3%) performed early decompression within 24 hours, and 40 (24,7%) until the first 48 hours. Regarding ASCI with incomplete neurological injury, 115 (71.0%) would operate in the first 12 hours. There was a significant difference in the proportion of surgeons that would operate ASCI within ≤ 24 hours, regarding the type of injury (complete injury:122 versus incomplete injury:155; p<0.01). In the case of patients with central cord syndrome without radiological evidence of instability, 152 surgeons (93.8%) would perform surgical decompression: 1 (0.6%) in the first 12 hours, 63 (38.9%) in 24 hours, 4 (2.5%) in 48 hours, 66 (40.7%) in the initial hospital stay, and 18 (11.1%) after neurologic stabilization. Conclusion All inquired surgeons favour early decompression, with the majority performing surgery in the first 24 hours. Decompression is performed earlier in cases of incomplete than in complete injuries. In cases of central cord syndrome without radiological evidence of instability, there is a tendency towards early surgical decompression, but the timing is still extremely variable. Future studies are needed to identify the ideal timing for decompression of this subset of ASCI patients.


Resumo Objetivo O objetivo do presente estudo foi avaliar a prática atual em termos de momento de realização da cirurgia em pacientes com lesão medularaguda (LMA) entre cirurgiões de coluna de países ibero-americanos. Métodos Estudo transversal descritivo com base em um questionário enviado por correio eletrônico para todos os membros da Sociedad Ibero Latinoamericana de Columna (SILACO, na sigla em espanhol) e sociedades associadas. Resultados Um total de 162 cirurgiões responderam a perguntas relacionadas ao momento da cirurgia. Sessenta e oito (42,0%) consideraram que a LMA com lesão neurológica completa deve ser tratada em até 12 horas, 54 (33,3%) realizariam a descompressão precoce em até 24 horas e 40 (24,7%) fariam este procedimento nas primeiras 48 horas. Em relação à LMA com lesão neurológica incompleta, 115 (71,0%) operariam nas primeiras 12 horas. Houve diferença significativa na proporção de cirurgiões que fariam o tratamento cirúrgico da LMA em ≤ 24 horas quanto ao tipo de lesão (lesão completa [122] versus lesão incompleta [155]; p<0.01). Em pacientes com síndrome medular central sem evidência radiológica de instabilidade, 152 cirurgiões (93,8%) realizariam a descompressão cirúrgica: 1 (0,6%) nas primeiras 12 horas, 63 (38,9%) em 24 horas, 4 (2,5%) em 48 horas, 66 (40,7%) no internamento inicial e 18 (11,1%) após a estabilização neurológica. Conclusão Todos os cirurgiões participantes favoreceram a descompressão precoce; a grande maioria realizaria a cirurgia nas primeiras 24 horas. A descompressão é feita antes em casos de lesões incompletas do que em lesões completas. Nos casos de síndrome medular central sem evidência radiológica de instabilidade, há uma tendência à descompressão cirúrgica precoce, mas o momento de intervenção ainda é extremamente variável. Estudos futuros são necessários para identificar o momento ideal para descompressão neste subconjunto de pacientes com LMA.

ABSTRACT

Abstract Objective The aim of the present study was to evaluate the current practice of using of methylprednisolone sodium succinate (MPSS) in acute spinal cord Injuries (ASCIs) among spine surgeons from Iberolatinoamerican countries. Methods A descriptive cross-sectional study design as a survey was conducted. A questionnaire composed of 2 sections, one on demographic data regarding the surgeons and MPSS administration, was sent by email to members of the Sociedad Ibero Latinoamericana de Columna (SILACO, in the Spanish acronym) and associated societies. Results A total of 182 surgeons participated in the study: 65.4% (119) orthopedic surgeons and 24.6% (63) neurosurgeons. Sixty-nine (37.9%) used MPSS in the initial management of ASCIs. There were no significant differences between countries (p = 0.451), specialty (p = 0.352), or surgeon seniority (p = 0.652) for the use of corticosteroids in the initial management of ASCIs. Forty-five (65.2%) respondents reported using an initial high-dose bolus (30 mg/Kg) followed by a perfusion (5.4 mg/ kg/h). Forty-six (66.7%) surgeons who used MPSS only prescribed it if the patients presented within 8 hours of the ASCI. Most of the surgeons (50.7% [35]) administered high-dose corticosteroids because of the conviction that it has clinal benefits and improves neurological recovery. Conclusion Results from the present survey show that MPSS use in ASCI is not widespread within spine surgeons and that the controversy regarding its use remains unresolved. This is probably due to the low level of evidence of the available data, to variations over the years, to inconsistencies in acute care protocols, and to health service pathways.


Resumo Objetivo O objetivo do presente estudo foi avaliar a prática atual de uso do succinato sódico de metilprednisolona (MPSS, na sigla em inglês) nas lesões agudas da medula espinal (LAMEs) entre cirurgiões de coluna de países ibero-americanos. Métodos Um estudo transversal descritivo foi realizado. O questionário continha duas seções, uma sobre os dados demográficos dos cirurgiões e acerca da administração de MPSS, e foi enviado por correio eletrônico aos membros da Sociedad Ibero Latinoamericana de Columna (SILACO, na sigla em espanhol) e sociedades associadas. Resultados No total, 182 cirurgiões participaram do estudo: 65,4% (119) eram cirurgiões ortopédicos e 24,6% (63), neurocirurgiões. Sessenta e nove (37,9%) usaram MPSS no tratamento inicial da LAME. Não houve diferenças significativas entre países (p = 0,451), especialidades (p = 0,352) ou senioridade do cirurgião (p =0,652) em relação ao uso de corticosteroides no tratamento inicial da LAME. Destes, 45 (65,2%) relataram a administração de um bolus de alta dose (30 mg/kg) seguido por perfusão (5,4 mg/kg/h). Quarenta e seis (66,7%) dos cirurgiões que usam MPSS apenas o prescrevem a pacientes tratados nas primeiras 8 horas após a LAME. A maioria dos cirurgiões (50,7% [35]) administrou corticosteroides em alta dose devido à convicção de seus benefícios clínicos e melhora da recuperação neurológica. Conclusão Os resultados do presente questionário mostram que o uso de MPSS na LAME não está disseminado entre os cirurgiões de coluna e que a controvérsia sobre sua administração ainda não foi resolvida. É provável que isto se deva ao baixo nível de evidência dos dados existentes, a variações ao longo dos anos, a inconsistências nos protocolos terapêuticos agudo e a diferentes sistemas de saúde.

ABSTRACT

O trauma raquimedular (TRM) é a principal etiologia relacionada à lesão medular em homens jovens. Em decorrência da complexidade ao atendimento desses pacientes e às suas complicações, os custos envolvidos nesses casos são vultosos. Objetivo: Avaliar os custos associados ao atendimento hospitalar e ambulatorial dos pacientes com lesão medular traumática num serviço universitário. Métodos: Este estudo baseou-se na revisão de informações clínicas sobre a lesão medular e suas complicações, bem como a busca de valores relacionados ao atendimento no período hospitalar e ambulatorial de indivíduos com lesão medular traumática num serviço universitário em 2009. Resultados: Foram contabilizados 51 pacientes com trauma na coluna vertebral, dos quais 14 apresentaram TRM (idade= 38,9 ± 20,8; homens: 86%). Os custos do atendimento foram R$402.908,68 na ausência de lesão medular e R$304.433,77 com lesão medular. Os custos do atendimento estiveram relacionados com o tempo de internação, o número de intercorrências clínicas e procedimentos cirúrgicos. A reabilitação correspondeu a 23% dos custos dos pacientes com TRM. Conclusão: Os custos relacionados ao atendimento do paciente com TRM são maiores que aqueles associados ao trauma de coluna sem lesão neurológica. O número de complicações clínicas correlaciona-se diretamente ao tempo de internação e os custos desse atendimento. A reabilitação corresponde a menor parte das despesas no cuidado aos pacientes com TRM


Spinal cord injury (SCI) is the main etiology related to spinal cord injury in young men. Due to the complexity of health care for these patients and their complications, the costs involved in these cases are high. Objective: To evaluate the costs associated with hospital and outpatient care for patients with traumatic spinal cord injury at a university service. Methods: This study was based on the review of clinical information about spinal cord injury and its complications, as well as the search for monetary amounts related to inpatient and outpatient care of individuals with traumatic SCI in a university service in 2009. Results: There were 51 patients with spinal trauma, of which 14 had SCI (age= 38.9 ± 20.8 years; men: 86%). Costs were R$402,908.68 in the absence of spinal cord injury and R$304,433.77 with spinal cord injury, and were statistically associated to the length of stay, the number of clinical complications and surgical procedures. Rehabilitation accounted for 23% of costs for patients with SCI. Conclusion: The costs related to the care of patients with SCI are higher than those associated with spinal trauma without neurological damage. The number of clinical complications is directly correlated with the length of hospital stay and the costs of this care. Rehabilitation corresponds to a smaller part of the expenses in the care of patients with SCI

ABSTRACT

ABSTRACT Introduction: We evaluated the outcomes of the selective intercostal artery reconstruction for preventing spinal cord injury during thoracoabdominal aortic aneurysm repair. Methods: We retrospectively assessed 84 consecutive patients who underwent thoracoabdominal aortic aneurysm repairs between 2004 and 2016. The mean age of the patients was 57.3 years. We performed preoperative multidetector computed tomography in 74 patients (88.0%) to identify the Adamkiewicz artery. Spinal cord injury preventive measures included motor evoked potential monitoring, hypothermia induction, Adamkiewicz artery or other intercostal artery reconstruction, and cerebrospinal fluid drainage. Results: The hospital death rate was 5.9%, and paraplegia occurred in four patients (4.7%). The Adamkiewicz artery or other intercostal arteries were reconstructed selectively in 46 patients (54.7%). Of these patients, 41 underwent postoperative multidetector computed tomography, which revealed occlusion of the reconstructed grafts in 23 patients (56.0%). There was no paraplegia in the patients who underwent reconstruction of the Adamkiewicz artery, which was patent on postoperative multidetector computed tomography. Univariate analysis showed no significant effect of various risk factors on the development of spinal cord injury. Conclusion: Outcome of open surgery for thoracoabdominal aortic aneurysm in our institution regarding spinal cord injury was satisfactory. The benefits of Adamkiewicz artery reconstruction remain inconclusive, and further larger studies are required to identify its validation for spinal cord protection in thoracoabdominal aortic aneurysm repair.

ABSTRACT

PURPOSE@#To identify risk factors for developing pressure ulcers (PUs) in the acute care period of traumatic spinal fracture patients with or without spinal cord injuries (SCIs).@*METHODS@#Data were collected prospectively in participating the National Spinal column/Cord Injury Registry of Iran (NSCIR-IR) from individuals with traumatic spinal fractures with or without SCIs, inclusive of the hospital stay from admission to discharge. Trained nursing staff examined the patients for the presence of PUs every 8 h during their hospital stay. The presence and grade of PUs were assessed according to the European Pressure Ulcer Advisory Panel classification. In addition to PU, following data were also extracted from the NSCIR-IR datasets during the period of 2015 - 2021: age, sex, Glasgow coma scale score at admission, having SCIs, marital status, surgery for a spinal fracture, American Spinal Injury Association impairment scale (AIS), urinary incontinence, level of education, admitted center, length of stay in the intensive care unit (ICU), hypertension, respiratory diseases, consumption of cigarettes, diabetes mellitus and length of stay in the hospital. Logistic regression models were used to estimate the unadjusted and adjusted odds ratio (OR) with 95% confidence intervals (CI).@*RESULTS@#Altogether 2785 participants with traumatic spinal fractures were included. Among them, 87 (3.1%) developed PU during their hospital stay and 392 (14.1%) had SCIs. In the SCI population, 63 (16.1%) developed PU during hospital stay. Univariate logistic regression for the whole sample showed that marital status, having SCIs, urinary incontinence, level of education, treating center, number of days in the ICU, age, and Glasgow coma scale score were significant predictors for PUs. However, further analysis by multiple logistic regression only revealed the significant risk factors to be the treating center, marital status, having SCIs, and the number of days in the ICU. For the subgroup of individuals with SCIs, marital status, AIS, urinary incontinence, level of education, the treating center, the number of days in the ICU and the number of days in the hospital were significant predictors for PUs by univariate analysis. After adjustment in the multivariate model, the treating center, marital status (singles vs. marrieds, OR = 3.06, 95% CI: 1.55 - 6.03, p = 0.001), and number of days in the ICU (OR = 1.06, 95% CI: 1.04 - 1.09, p < 0.001) maintained significance.@*CONCLUSIONS@#These data confirm that individuals with traumatic spinal fractures and SCIs, especially single young patients who suffer from urinary incontinence, grades A-D by AIS, prolonged ICU stay, and more extended hospitalization are at increased risk for PUs; as a result strategies to minimize PU development need further refinement.

ABSTRACT

Introduction:There are few detailed evaluations of upper extremity function in Japan, especially for cervical spinal cord injury (CSCI). The capabilities of upper extremity test (CUE-T) evaluates upper extremity function, is specialized for CSCI, and is internationally used;however, there are few reports from Japan. This study verified the reliability, validity, and responsiveness of the CUE-T in Japan.Methods:We determined the interrater reliability, internal consistency, weighted kappa coefficient, intraclass correlation coefficient, and Cronbach's α coefficient for acute and chronic CSCI. The correlation coefficient with other evaluations was calculated and validated. Furthermore, the evaluation was performed twice at regular intervals, and the correlation between the change in CUE-T and other evaluations and the sensitivity to change using the standardized response mean (SRM) were verified.Results:The weighted kappa coefficient was 0.61-1.00, intraclass correlation coefficient was ≥0.9, and Cronbach's α coefficient were ≥0.9. The CUE-T and other evaluation methods showed moderate to strong correlations. In addition, the amount of change between CUE-T and the other evaluations were significantly correlated, and the SRM was ≥0.8.Discussion:In Japan, the CUE-T has been suggested to have good reliability, validity, responsiveness, and interpretability as an evaluation of upper extremity function in patients with CSCI. We will continue to verify the interpretability of the CUE-T and consider its dissemination in Japan.

ABSTRACT

PURPOSE@#There are many infectious and inflammatory causes for elevated core-body temperatures, though they rarely pass 40 ℃ (104 ℉). The term "quad fever" is used for extreme hyperpyrexia in the setting of acute cervical spinal cord injuries (SCIs). The traditional methods of treating hyperpyrexia are often ineffective and reported morbidity and mortality rates approach 100%. This study aims to identify the incidence of elevated temperatures in SCIs at our institution and assess the effectiveness of using a non-invasive dry water temperature management system as a treatment modality with mortality.@*METHODS@#A retrospective analysis of acute SCI patients requiring surgical intensive care unit admission who experienced fevers ≥ 40 ℃ (104 ℉) were compared to patients with maximum temperatures < 40 ℃. Patients ≥18 years old who sustained an acute traumatic SCI were included in this study. Patients who expired in the emergency department; had a SCI without radiologic abnormality; had neuropraxia; were admitted to any location other than the surgical intensive care unit; or had positive blood cultures were excluded. SAS 9.4 was used to conduct statistical analysis.@*RESULTS@#Over the 9-year study period, 35 patients were admitted to the surgical intensive care unit with a verified SCI. Seven patients experienced maximum temperatures of ≥ 40 ℃. Six of those patients were treated with the dry water temperature management system with an overall mortality of 57.1% in this subgroup. The mortality rate for the 28 patients who experienced a maximum temperature of ≤ 40 ℃ was 21.4% (p = 0.16).@*CONCLUSION@#The diagnosis of quad fever should be considered in patients with cervical SCI in the presence of hyperthermia. In this study, there was no significant difference in mortality between quad fever patients treated with a dry water temperature management system versus SCI patients without quad fever. The early use of a dry water temperature management system appears to decrease the mortality rate of quad fever.

ABSTRACT

Spinal cord injury is a severe central nervous system disorder that often results in sensory and motor impairments below the level of injury, accompanied by respiratory failure, gastrointestinal disturbances, and hemodynamic instability. Existing treatment such as early decompression surgery and steroid-based shock therapy has limited effectiveness and can lead to serious complications. Meanwhile, the rehabilitation therapy is costly and can only provide limited functional recovery. Spinal cord stimulation (SCS), by stimulating and regulating residual neurons in the lower spinal cord, can effectively promote motor function recovery in patients with spinal cord injury. The introduction of intelligent precision-assistive technologies can help to create more precise and individualized neuro-regulation and rehabilitation strategies tailored to the severity, segment, and course of spinal cord injury. These strategies, coupled with real-time feedback and continuous algorithm adjustments, enabled remote and secure control of SCS, enhancing the treatment effectiveness and safety for patients with spinal cord injury, which can help to develop more effective rehabilitation intervention plans and further increase the clinical translational value. In this review, the authors summarized the research progress in the application of intelligent precision-assistive technology in SCS for the treatment of spinal cord injury, so as to provide valuable insights for the rehabilitation of SCI.

ABSTRACT

Objective:To compare the efficacies of negative pressure wound therapy (NPWT) and functional dressings in primary repair of spinal cord injury complicated with lacunar soft tissue defects.Methods:A retrospective cohort study was conducted to analyze the clinical data of 30 patients with spinal cord injury complicated with lacunar soft tissue defects. The patients were admitted to West China Hospital, Sichuan University from January 2020 to December 2022, including 20 males and 10 females; aged 23-54 years [(42.1±7.8)years]. Wound site was located at the sacrococcygeal region in 16 patients, the buttock in 11, and the femoral trochanter in 3. Wound area was 28-36 cm 2 [(32.1±2.1)cm 2]. Time of wound formation was at range of 1-4 months [(2.0±0.8)months]. Among them, 15 patients received functional dressing treatment after mechanical/ultrasonic debridement (dressing treatment group), and 15 patients received NPWT treatment on the basis of mechanical/ultrasonic debridement (negative pressure treatment group). The following items were compared between the two groups: the time of primary wound repair, results of bacterial culture of wound secretions before and at the end of primary wound repair, and levels of serum interleukin-6 (IL-6) and C-reactive protein (CRP) as well as Bates-Jensen wound assessment tool (BWAT) score before, at 5 days after the primary repair and at the end of the primary repair. Results:All the patients were followed up for 3-6 months [(4.1±0.9)months]. The time of primary wound repair in the negative pressure treatment group was (13.4±2.3)days, which was markedly shorter than that in the dressing treatment group [(22.8±2.5)days] ( P<0.01). Before the primary repair, 11 patients in the negative pressure treatment group showed positive bacterial culture of wound secretions [73.3% (11/15)], and 9 patients in the dressing treatment group were positive [60.0% (9/15)] ( P>0.05). At the end of primary repair, there was 1 patient with positive bacterial culture of wound secretions in the negative pressure treatment group [6.7% (1/15)], which was less than 7 patients in the dressing treatment group [46.7% (7/15)] ( P<0.05). The numbers of positive patients at the end of the primary repair were lower than those before the primary repair in both groups, and the difference in the negative pressure treatment group was statistically significant ( P<0.01), with no significant difference found in the dressing treatment group ( P>0.05). Before the primary repair, the IL-6, CRP and BWAT score were 20.5(8.4, 32.3)pg/ml, 24.2(14.7, 33.0)mg/L, and (37.1±4.8)points in the negative pressure treatment group, comparable with 13.8(11.8, 35.4)pg/ml, 23.6(13.1, 52.3)mg/L, and (35.2±4.7)points in the dressing treatment group (all P>0.05). At 5 days after primary repair, the IL-6, CRP and BWAT score in the negative pressure treatment group were 20.2(7.9, 28.6)pg/ml, 20.0(11.6, 30.5)mg/L, and (34.9±4.3)points, comparable with 11.6(8.9, 20.6)pg/ml, 25.3(10.0, 50.3)mg/L, and (35.2±4.5)points in the dressing treatment group (all P>0.05). At the end of primary repair, the IL-6, CRP and BWAT score were 2.3(1.5, 4.5)pg/ml, 4.8(3.7, 6.9)mg/L, and (23.6±1.8)points in the negative pressure treatment group, statistically different from 4.4(3.3, 6.9)pg/ml, 8.4(5.5, 31.4)mg/L, and (31.4±3.3)points in the dressing treatment group (all P<0.01). The IL-6, CRP and BWAT score at the end of the primary repair were significantly different compared with those before and at 5 days after the primary repair in the two groups ( P<0.05 or 0.01). However, no significant difference was found between the two groups before and at 5 days after the primary repair (all P>0.05). Conclusion:Compared with functional dressings, NPWT can shorten the time required for primary repair of spinal cord injury complicated with lacunar soft tissue defects, control the inflammatory state of the wound, improve the trend of wound healing, and create a good condition for secondary repair treatment of the wound.

ABSTRACT

Objective:To compare the efficacy of cervical decompression performed at different times in the treatment of incomplete cervical spinal cord injury.Methods:A multicenter retrospective cohort study was conducted to analyze the clinical data of 96 patients with incomplete cervical spinal cord injury admitted to six hospitals including Honghui Hospital affiliated to Xi'an Jiaotong University, etc, from May 2018 to May 2021. There were 36 females and 60 males, aged 28-42 years [(35.2±6.7)years]. The injured segments were at C 3 in 7 patients, C 4 in 15, C 5 in 20, C 6 in 23 and C 7 in 31. According to the American Spinal Injury Association (ASIA) scale, there were 59 patients with grade B, 27 grade C, and 10 grade D. A total of 36 patients underwent cervical decompression within 24 hours after injury (early group), 33 patients within 24-72 hours after injury (late group), and 27 patients within 4-14 days after injury (delayed group). The operation time, intraoperative blood loss, postoperative drainage, length of hospital stay, Cobb angle, height of intervertebral space and space occupation of the spinal canal before surgery and at postoperative 3 days, and ASIA score, ASIA motor score, ASIA light tactile score, ASIA acupuncture sensation score, visual analog scale (VAS) score, Japanese Orthopedic Association (JOA) score, neck dysfunction index (NDI) before surgery and at postoperative 3 months, 1 year and at the last follow-up and incidence of complications were compared among the three groups. Results:All the patients were followed up for 12-21 months [(16.4±4.2)months]. There was no significant difference in the operation time among the three groups (all P>0.05). The intraoperative blood loss and postoperative drainage volume in the early group were (312.5±5.2)ml and (165.3±45.8)ml, which were higher than those in the late group [(253.5±40.0)ml, (120.4±60.6)ml] and the delayed group [(267.3±36.8)ml and (130.4±38.6)ml] (all P<0.01). There was no significant difference between the late group and the delayed group (all P>0.05). The length of hospital stay in the early group was (5.2±1.6)days, which was shorter than that in the late group [(7.6±2.3)days] and the delayed group [(8.0±1.3)days] (all P<0.05), but there was no significant difference between the late group and the delayed group ( P>0.05). There was no significant difference in the Cobb angle, height of intervertebral space and space occupation of the spinal canal among the three groups before and at postoperative 3 days (all P>0.05). There was no significant difference in the ASIA score, ASIA motor score, ASIA light tactile score, ASIA acupuncture sensation score, VAS score, JOA score and NDI among the three groups before surgery (all P>0.05). At postoperative 3 months, 1 year and at the last follow-up, the ASIA grading of the early group was better than that of the late group and the delayed group ( P<0.05 or 0.01), but there was no statistically significant difference between the late group and the delayed group (all P>0.05). The ASIA motor scores of the early group were (56.4±4.5)points, (76.3±3.6)points and (85.4±6.5)points at postoperative 3 months, postoperative 1 year and the last follow-up, respectively, which were higher than those in the late group [(52.3±2.4)points, (60.3±8.6)points and (72.3±2.4)points] and the delayed group [(51.9±2.3)points, (62.8±4.6)points and (71.9±1.3)points]; the ASIA light tactile scores of the early group were (70.2±2.9)points, (72.6±4.3)points and (78.3±2.3)points, which were higher than those in the late group [(66.2±3.7)points, (68.3±1.6)points and (73.3±1.6)points] and the delayed group [(65.2±2.1)points, (67.8±1.9)points and (72.3±2.5)points]; acupuncture sensation scores of the early group were (71.9±3.1)points, (80.1±3.8)points and (89.1±7.6)points, which were higher than those in the late group [(67.4±2.7)points, (72.6±3.7)points and (77.9±1.8)points] and the delayed group [(68.3±2.2)points, (72.6±3.1)points and (77.2±1.9)points] (all P<0.05). VAS scores of the early group at postoperative 3 months, 1 year and at the last follow-up were (4.3±0.6)points, (2.4±0.3)points and (1.6±0.2)points, which were lower than those in the late group [(5.1±1.3)points, (4.1±0.6)points and (3.0±0.6)points] and the delayed group [(5.0±1.7)points, (4.0±0.8)points and (3.1±0.2)points]; JOA scores of the early group were (12.8±1.6)points, (14.4±2.6)points and (17.9±3.3)points, which were higher than those in the late group [(11.9±1.9)points, (13.3±1.6)points and (8.9±1.3)points] and the delayed group [(11.6±1.8)points, (13.2±1.4)points and (9.3±2.1)points]; NDI scores of the early group were 12.1±3.3, 10.1±2.1 and 7.3±1.4, which were lower than those in the late group (14.4±3.1, 12.3±1.6 and 8.9±1.3) and the delayed group (14.1±2.3, 12.9±1.9 and 9.5±2.1) (all P<0.05). There was no significant difference in all the above-mentioned scores at postoperative 3 months, 1 year and at the last follow-up between the late group and the delayed group (all P>0.05). The incidence of complications was 25.0% (9/36) in the early group, 27.3% (9/33) in the late group and 37.0% (10/27) in the delayed group (all P>0.05). Conclusion:Compared with within 24-72 hours and 4-14 days after injury, cervical decompression performed within 24 hours after injury for patients with incomplete cervical spinal cord injury can shorten the length of hospital stay, improve the function of the spinal cord nerves and relieve pain, with no increase of the incidence of complications.

ABSTRACT

Objective:To explore the changes of mitophagy- and apoptosis-related protein expressions after spinal cord injury in rats and its related mechanism.Methods:Ninety-six healthy female SD rats were divided into sham surgery group ( n=48) and spinal cord injury group ( n=48) according to the random number table. Each group was divided into six time points of 1, 3, 7, 14, 21 and 28 days with 8 rats at each time point. In the sham surgery group, the T 8-9 spinous processes and vertebral plates were removed without damage to the spinal cord; in the spinal cord injury group, the spinal cord injury model was established using Allen′s method. At each post-injury time point in two groups, BBB score was used to evaluate the motor function of the rats; HE staining was used to observe the histopathological changes of the spinal cord; immunofluorescence was used to observe the co-localized positive cells of the voltage-dependent anion channel protein 1 (VDAC1) with microtubule-associated protein 1 light chain 3 (LC3) II, E3 ubiquitin ligase (Parkin), and polyubiquitin-binding protein (p62); Western blotting was used to observe expressions of the mitochondrial LC3 II/LC3 I, cytoplasmic Parkin, mitochondrial Parkin, cytoplasmic p62, mitochondrial p62, cytoplasmic apoptotic proteins (Bax), mitochondrial Bax, cytoplasmic cytochrome C (Cyt C), and mitochondrial Cyt C. Results:(1) Compared with the sham surgery group [(21.00±0.00)points at all time points], the BBB scores in the spinal cord injury group were (0.94±0.50)points, (1.69±0.70)points, (4.13±0.99)points, (11.81±1.03)points, (15.06±1.12)points and (18.38±0.83)points at 1, 3, 7, 14, 21 and 28 days after injury, respectively ( P<0.01). (2) Compared with the sham surgery group, the structure in the spinal cord injury group was significantly disrupted at 1 and 3 days after injury, when a large number of hemorrhagic foci, inflammatory cell infiltration, neuronal swelling, and cavity formation were observed. At 7 and 14 days after injury, the number of hemorrhagic foci was markedly reduced compared with the earlier period, when swollen neuronal cytosols, inflammatory cell infiltration and a large number of cavities were found. At 21 and 28 days after injury, a large number of cells were seen to be involved in the repair and the arrangement of cells was disorganized. (3) Compared with the sham surgery group, the number of co-localized positive cells of VDAC1 with LC3 II, Parkin and p62 separately in the spinal cord injury group, markedly increased at 1 and 3 days after surgery, and gradually decreased after that. (4) In the sham surgery group and at 1, 3, 7, 14, 21 and 28 days after injury in the spinal cord injury group, the mitochondrial LC3 II/LC3 I expression levels were 0.56±0.05, 1.00±0.05, 1.19±0.11, 0.86±0.05, 0.80±0.08, 0.66±0.13 and 0.51±0.11, respectively; the cytoplasmic Parkin expression levels were 0.80±0.13, 0.47±0.08, 0.29±0.06, 0.57±0.07, 0.70±0.05, 0.97±0.09 and 0.88±0.12, respectively; the mitochondrial Parkin expression levels were 0.67±0.09, 1.07±0.18, 1.27±0.15, 0.82±0.12, 0.59±0.09, 0.53±0.13 and 0.57±0.14, respectively; the cytoplasmic p62 expression levels were 1.25±0.08, 1.04±0.04, 0.94±0.05, 1.09±0.05, 1.19±0.06, 1.20±0.04 and 1.27±0.05, respectively; the mitochondrial p62 expression levels were 0.61±0.06, 0.88±0.07, 1.09±0.09, 0.98±0.07, 0.70±0.08, 0.68±0.08 and 0.60±0.09, respectively; the cytoplasmic Bax expression levels were 0.92±0.08, 0.67±0.07, 0.36±0.08, 0.48±0.08, 0.69±0.06, 0.88±0.11 and 0.94±0.08, respectively; the mitochondrial Bax expression levels were 0.57±0.04, 0.74±0.04, 0.91±0.05, 0.76±0.05, 0.63±0.08, 0.61±0.05 and 0.57±0.05, respectively; the cytoplasmic Cyt C expression levels were 0.28±0.05, 0.81±0.07, 1.12±0.08, 0.64±0.07, 0.67±0.13, 0.60±0.11 and 0.37±0.06, respectively; and the mitochondrial Cyt C expression levels were 1.02±0.07, 0.91±0.14, 0.37±0.07, 0.73±0.06, 0.91±0.11, 0.95±0.13 and 1.10±0.15, respectively. Compared with the sham surgery group, in the spinal cord injury group mitochondrial LC3II/LC3I had the highest expression level at 3 days after injury; cytoplasmic Parkin had the lowest expression level at 3 days after injury; mitochondrial Parkin had the highest expression level at 3 days after injury; cytoplasmic p62 had the lowest expression level at 3 days after injury; mitochondrial p62 had the highest expression level at 3 days after injury; cytoplasmic Bax had the lowest expression level at 3 days after injury; mitochondrial Bax had the highest expression level at 3 days after injury; cytoplasmic Cyt C had the highest expression level at 3 days after injury; and mitochondrial Cyt C had the lowest expression level at 3 days after injury. Conclusion:Mitochondrial autophagy and apoptosis are enhanced after spinal cord injury in rats, and the potential mechanism may be associated with the transfer of Parkin and P62 from the cytoplasm to the damaged mitochondria for enhanced mitophagy and the release of a large amount of Cyt C from the mitochondria caused by the transfer of Bax from the cytoplasm to the damaged mitochondria for enhanced apoptosis.
