Orthostatic support in paraplegic and amputee patients: a controlled trial / Suporte ortostático em paraplégicos e amputados: um ensaio controlado

ABSTRACT Introduction: Functional incapacity caused by physical alterations leads to significant limitations in daily activities and has a major impact on the return of people with disabilities to the social space and the workplace. 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.

Associação de estimulação por ondas de choque a toxina botulínica e baclofeno durante a reabilitação de paciente com lesão medular e trauma cranioencefálico: relato de caso / Association of extracorporeal shockwave stimulation to botulinum toxin and baclofen during an in-patient rehabilitation in spinal cord injury and traumatic brain injury: case report

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.

Condicionantes para la participación laboral de las personas con discapacidad por lesión medular atendidas en un instituto especializado de rehabilitación

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.

Treatment of Acute Spinal Cord Injuries: A Survey Among Iberolatinoamerican Spine Surgeons - Part 1: Use of High-Dose Corticosteroids / Tratamento das lesões agudas da medula espinal: Uma pesquisa entre cirurgiões de coluna iberoamericanos - Parte 1: Uso de corticosteroides em altas doses

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.

Treatment of Acute Spinal Cord Injuries: A Survey Among Iberolatinoamerican Spine Surgeons - Part 2 Timing to Surgery / Tratamento de lesões agudas da medula espinal: Uma pesquisa entre cirurgiões de coluna iberoamericanos - Parte 2: Momento da cirurgia

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.

Estudo dos determinantes dos custos no atendimento dos pacientes com lesão medular decorrente de trauma raquimedular / Study of cost determinants in the care of subjects with traumatic spinal cord injury

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

Impact of Reconstructing Intercostal Artery on Spinal Cord Circulation During Open Surgery for Thoracoabdominal Aortic Aneurysm

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.

Optimal evidence analysis for the nursing management of limb spasm in patients with spinal cord injury / 中华创伤杂志

Objective:To explore the optimal evidence for the nursing management of limb spasm in patients with spinal cord injury.Methods:Based on the "6S" evidence model, the databases including CNKI, Wanfang, PubMed and Cochrane Library, the guideline websites such as the National Guideline Clearinghouse, Guidelines International Network and Registered Nurses′ Association of Ontario, and the websites of professional associations such as the Royal College of Physicians, American Spinal Injury Association and Canadian Spine Association were systematically searched. Search period of each database was set from the year of inception until July 2022. Two investigators independently screened the literatures related to the management of limb spasm in patients with spinal cord injury, and conducted quality evaluation and evidence recommendation level evaluation.Results:Totally 17 literatures consisting of 6 guidelines, 3 expert consensuses, 5 systematic reviews, 2 evidence summaries, and 1 clinical decision were included. Moreover, 30 pieces of evidence were summarized from 3 aspects, including evaluation and identification, drug therapy (chemical denervation, and oral medication), rehabilitation training (hydrotherapy, electrical stimulation, magnetic stimulation, vibration therapy, heat and cold therapy, body position, and exercise therapy).Conclusion:Nursing staff can set up a multidisciplinary team according to the clinical environment and take into consideration of the characteristics of spinal cord injury patients to provide personalized interventions involving evaluation and identification, drug therapy, rehabilitation training, etc., so as to alleviate the degree of limb spasm.

Effect of Enolase inhibitor on autophagy and motor function after spinal cord injury in rats / 中华创伤杂志

Objective:To investigate the effect of Enolase inhibition (ENOblock) on autophagy- related protein expression and motor function promotion after spinal cord injury in rats.Methods:A total of 160 female SD rats were divided into sham-operation group, 3-methyladenine (3-MA) autophagy inhibitor treatment group (3-MA group), spinal cord injury group and ENOblock treatment group (ENOblock group) according to the random number table, with 40 rats per group. Back laminectomy without injury to the spinal cord was performed in sham-operation group. Spinal cord injury at T 8 was induced by using a modified Allen weight-drop apparatus to establish a spinal cord injury model in the rest three groups. 3-MA and ENOblock groups were injected 3-MA (2.5 mg/kg) and ENOblock (100 μg/kg) into the caudal vein immediately after injury, respectively. Sham-operation and spinal cord injury groups were injected same dose of isotonic sodium chloride solution into the caudal vein. At 1, 3, 7, 14 and 21 days after injury, BBB score was used to evaluate lower limb motor function. At day 3 after injury, the ratio of microtubule-associated protein 1 light chain 3 (LC3)-II to LC3-I and protein expressions of autophagy effector protein (Beclin-1) and polyubiq-uitinbinding protein (p62) were detected by Western blotting. At day 7 after injury, LC3-Ⅱ and Beclin-1 positive cells in the injured area of the spinal cord were determined by immunofluorescence staining. At day 3 after injury, the mRNA expressions of Beclin-1 and Enolase in the injured area of the spinal cord were detected by RT-PCR. Results:At 1, 3, 7, 14 and 21 days after injury, BBB score was lowered in 3-MA group [(1.4±1.1)points, (2.4±0.9)points, (3.8±1.8)points, (7.6±1.1)points, (9.0±2.1)points], spinal cord injury group [(0.8±0.5)points, (1.8±0.9)points, (3.6±0.9)points, (6.2±1.3)points, (8.0±0.7)points] and ENOblock group [(2.0±0.9)points, (2.2±0.8)points, (4.8±1.1)points, (10.6±1.5)points, (13.2±0.8)points] compared to sham-operation group [(21.0±0.0)points at all time points] (all P<0.05). Moreover, the score in ENOblock group was significantly higher than that in spinal cord injury group at 14, 21 days after injury, and the score in 3-MA group was significantly higher than that in spinal cord injury group at day 21 after injury (all P<0.05). At day 3 after injury, Western blotting showed that the ratio of LC3-II to LC3-I and protein expressions of Beclin-1 and p62 were 0.46±0.10, 0.41±0.03, 0.81±0.03 in sham-operation group, 0.66±0.06, 0.69±0.02, 0.59±0.05 in 3-MA group, 0.85±0.06, 1.07±0.03, 0.41±0.02 in spinal cord injury group and 0.68±0.06, 0.66±0.08, 0.55±0.02 in ENOblock group. By comparison, spinal cord injury group showed significantly higher ratio of LC3-II to LC3-I and protein expression of Beclin-1 and significantly lower protein expression of p62 than sham-operation group (all P<0.05); 3-MA and ENOblock groups showed significantly lower ratio of LC3-II to LC3-I and protein expression of Beclin-1 and significantly higher protein expression of p62 than spinal cord injury group (all P<0.05); there was no significant difference in the ratio of LC3-II to LC3-I and protein expressions of Beclin-1 and p62 between 3-MA and ENOblock groups (all P>0.05). At day 7 after injury, immunofluorescence staining showed that LC3-II and Beclin-1 positive cells in 3-MA and ENOblock groups were less than those in spinal cord injury group. At day 3 after injury, RT-PCR showed that mRNA expressions of Beclin-1 and Enolase in spinal cord injury group (1.08±0.16, 0.98±0.17) were higher than those in sham-operation group (0.25±0.06, 0.29±0.03). Moreover, mRNA expressions of Beclin-1 and Enolase in 3-MA group (0.77±0.11, 0.72±0.04) and ENOblock group (0.81±0.10, 0.64±0.09) were lower than those in spinal cord injury group (all P<0.05). There was no significant difference in mRNA expressions of Beclin-1 and Enolase between 3-MA and ENOblock groups (all P>0.05). Conclusions:Autophagy activity is significantly up-regulated after spinal cord injury in rats. ENOblock can inhibit autophagy and promote motor function recovery in rats by regulating the expression of autophagy-related proteins.

Basic researches over spinal cord injury: problems and countermeasures / 中华创伤杂志

Spinal cord injury leads to extremely high mortality and disability rates and its treatment has always been a global challenge. The survival of patients with spinal cord injury is partially lengthened with the development of medical treatments, but the clinical outcome is still not satisfactory. Some important progress has been made in the basic researches over spinal cord injury, such as analysis of repair mechanism of spinal cord injury and development of cellular therapies and biological scaffolds of spinal cord injury in China. However, some basic researches show insufficient understanding of the microenvironment and animal model of spinal cord injury and lack support from clinical problems, leading to too simplistic or contradictory conclusions. There is an urgent need to reexamine the research methods and carry out basic and clinical translational researches. Therefore, the authors discuss the key problems and difficulties in basic researches over spinal cord injury and propose improvement suggestions, aiming to provide a reference for conducting basic researches correctly and accelerating clinical innovational transformation.

Research progress in brain computer interface technology applied to motor recovery after spinal cord injury / 中华创伤杂志

Most patients with spinal cord injury suffer from limb motor dysfunction. Given drugs, surgery and other conventional treatments are often not effective, the patients can only rely on a wheelchair to move or even lie in bed for a long time, seriously affecting their quality of life. Brain computer interface (BCI) technology provides a non-muscular pathway for the recovery of motor function in patients with spinal cord injury, which allows the patients to recover partial motor function through the normal function of their own non-diseased spinal cord or external mechanical devices. After decades of development of BCI technology, signal collection devices can identify and collect the motor signals of the brain more accurately, transform the signal by characteristic analysis, and implement the brain command by using the output device. A large number of experimental and clinical studies have also proved that the application of BCI technology in patients with spinal cord injury can partially improve the motor function of upper and lower limbs. Therefore, BCI technology has attracted more and more attention. The authors summarized the BCI technology and its influence on motor function rehabilitation in patients with spinal cord injury, so as to provide a reference for the rehabilitation of motor function in patients with spinal cord injury.

Research progress in characteristics of intestinal flora and intestinal flora-targeted therapeutic methods in patients with spinal cord injury / 中华创伤杂志

Patients with spinal cord injury is associated with seriously affected gastrointestinal function and imbalance of intestinal flora, leading to increased inflammation of spinal cord nerves. With the proposal of the theory of gut microbiota-gut-brain axis in recent years, the regulatory role of gut microbiota in the central nervous system and gastrointestinal system has gradually attracted attention. Although a considerable number of studies have focused on the effects of intestinal flora characteristics on spinal cord nerve function repair in patients with spinal cord injury from different perspectives, there are numerous research models for treating spinal cord injury with intestinal flora as intervention targets and remains a lack of unified and effective clinical treatment methods. In this paper, the authors review the research progress in characteristics of intestinal microflora and intestinal microflora-targeted therapeutic methods in patients with spinal cord injury, hoping to provide a reference for the clinical treatment and basic research of spinal cord injury.

Pressure ulcers and acute risk factors in individuals with traumatic spinal fractures with or without spinal cord injuries: A prospective analysis of the National Spinal Column/Cord Injury Registry of Iran (NSCIR-IR) data / 中华创伤杂志(英文版)

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.

Fatores que implicam na sexualidade dos pacientes com lesão medular / Factors that imply on the sexuality of patients with spindle injury

A Lesão Medular acomete as funções sexuais devido à interrupção dos estímulos neurais, determinando as disfunções sexuais que dependem do nível, tipo da lesão, fatores físicos, psíquicos e sociais. Surge, assim, o processo de reabilitação sexual no sentido de promover a reinserção desses indivíduos. Objetivo: Identificar as alterações fisiológicas, fatores psicológicos e sociais intrínsecos, dentro do contexto da sexualidade em indivíduos com Lesão Medular. Métodos: Trata-se de um estudo exploratório, descritivo, de abordagem quantitativa, nos quais foram incluídos 50 participantes com Lesão Medular em um Centro de Reabilitação. O instrumento de coleta utilizado foi o Questionário de Sexualidade Humana na Lesão Medular, abordando aspectos da sexualidade nos períodos antes e após a lesão. Resultados: A sexualidade foi afetada negativamente, sendo que a vida sexual ativa, após a lesão, teve em média de frequência 2,02 (±1,80), vontade 7,15 (±2,66) e satisfação sexual 4,80 (±3,08), mostrando que esta reduziu significativamente. Quanto às respostas sexuais, a ejaculação é a mais afetada: média 0,61 (±2,08), seguida da ereção 3,02 (±3,20), orgasmo masculino 2,95 (±3,49) e orgasmo feminino 0,22 (±0,67). Além disso, foi possível constatar uma lacuna existente na abordagem da temática pelos profissionais de saúde, onde apenas 21(42%) dos indivíduos receberam algum tipo de aconselhamento sexual após a lesão. Conclusão: Tornaram-se claros os impactos negativos das alterações enfrentadas após a Lesão Medular quanto aos ajustes físicos, psicológicos e sociais ressaltando a necessidade de capacitação dos profissionais para que estejam aptos a realizarem a reabilitação sexual desses indivíduos
