RESUMEN
Patients with spinal cord injury (SCI) suffer from major bowel dysfunction, whose exact pathophysiology, particularly the involvement of the enteric nervous system or epithelial dysfunction is poorly understood. Herein, we aimed to characterize the mucosal biopsies of the right and left colon in SCI patients vs controls (CT): (1) remodeling of key enteric neurotransmitters, (2) remodeling of enteroendocrine cells, and (3) mucosal inflammation compared to those in controls. In SCI, mucosal ACh concentration was lower in the right colon as compared to CT, but no change was observed in the left colon, and AChE expression was lower in both the right and left colons than in CT. While the VIP concentration was similar in the right and left colons, VIP mRNA expression was increased in the right colon and decreased in the left colon, in SCI patients as compared to CT. Interestingly, 5-HT concentration was reduced in the left colon but not in the right colon in SCI patients. Moreover, in SCI patients, as compared to CT, SERT mRNA expression was selectively increased in the left colon while TPH1 mRNA expression was increased in the right and left colons. Although mucosal TNFα and IL-1ß mRNA expression did not significantly differ between SCI and CT groups, we identified a significant positive correlation between TNFα and IL-1ß mRNA expression and left colon transit time in the SCI group. In conclusion, region-specific changes occur in the enteric neurotransmitter, serotonergic, and inflammatory pathways in the colon of SCI patients. The significant correlations between these pathways and clinical parameters in the left colon further set a scientific basis for designing therapeutic targets to improve colonic motor dysfunction in patients.Biobank information: Spinal cord injury patients: PHRC ConstiCAPE-clinical trial NCT02566746.

INTRODUCTION: The prevalence and risk factors of anxiety and depression symptoms in relatives of moderate to severe traumatic brain injury (TBI) survivors have not been thoroughly investigated. METHODS: Ancillary study of a multicentric prospective randomized-controlled trial in nine university hospitals in 370 moderate-to-severe TBI patients. TBI survivor-relative dyads were included in the 6th month of follow-up. Relatives responded to the Hospital Anxiety and Depression Scale (HADS). The primary endpoints were the prevalence of severe symptoms of anxiety (HADS-Anxiety ≥ 11) and depression (HADS-Depression ≥ 11) in relatives. We explored the risk factors of severe anxiety and depression symptoms. RESULTS: Relatives were predominantly women (80.7%), spouse-husband (47.7%), or parents (39%). Out of the 171 dyads included, 83 (50.6%) and 59 (34.9%) relatives displayed severe symptoms of anxiety and depression, respectively. Severe anxiety symptoms in relatives were independently associated with the patient's discharge at home (OR 2.57, 95%CI [1.04-6.37]) and the patient's higher SF-36 Mental Health domain scores (OR 1.03 95%CI [1.01-1.05]). Severe depression symptoms were independently associated with a lower SF-36 Mental Health domain score (OR = 0.98 95%CI [0.96-1.00]). No ICU organization characteristics were associated with psychological symptoms in relatives. DISCUSSION: There is a high prevalence of anxiety and depression symptoms among relatives of moderate-to-severe TBI survivors at 6 months. Anxiety and depression were inversely correlated with the patient's mental health status at 6 months. CONCLUSIONS: Long-term follow-up must provide psychological care to relatives after TBI.

AIM: To compare transanal irrigation with conservative bowel management for the treatment of bowel dysfunction in Spina bifida (SB) patients. METHODS: Patients with SB and bowel dysfunction were randomly assigned to receive either transanal irrigation or conservative bowel management. The effectiveness of the treatment was defined as a decrease of 4 points in the neurogenic bowel dysfunction (NBD) score at week 10. Data on incontinence (Cleveland scores; Jorge-Wexner [JW]) and constipation (Knowles-Eccersley-Scott Symptom Constipation Score [KESS]) were recorded at 10 and 24 weeks after inclusion. Data were analysed on an intention-to-treat basis. RESULTS: A total of 34 patients were randomised: 16 patients to conservative bowel management and 18 patients to transanal irrigation. A total of 19/31 (61%) patients improved at week 10, 13 (76%) in the transanal irrigation group versus six (43%) in the conservative group (p = 0.056). In the irrigation group, the decrease in NBD score was -6.9 (-9.9 to -4.02) versus -1.9 (-6.5 to -2.8) in the conservative group (p = 0.049 in univariate and p = 0.004 in multivariate analysis). The NBD, Cleveland (JW and KESS) and Rosenberg scores were significantly lower in the transanal irrigation group than in the conservative bowel management group at week 10. CONCLUSIONS: This prospective, randomised, controlled, multicentre study in adult patients with SB suggests that transanal irrigation may be more effective than conservative bowel management.

PURPOSE: We assess the efficacy, safety, and predictive factors for failure of synthetic mid-urethral slings for the treatment of urinary incontinence in a large cohort of women with neurogenic lower urinary tract dysfunction. MATERIALS AND METHODS: Women aged 18 years or older who received a synthetic mid-urethral sling for stress urinary incontinence or mixed urinary incontinence in 3 centers between 2004 and 2019 and who had a neurological disorder were included. Exclusion criteria were less than 1 year of follow-up, concomitant pelvic organ prolapse repair, previous synthetic sling implantation, and no baseline urodynamics. The primary outcome was surgical failure, defined as recurrence of stress urinary incontinence during follow-up. Kaplan-Meier analysis was used to estimate the 5-year failure rate. Adjusted Cox proportional hazard model was used to identify factors associated with surgical failure. Complications and reoperations during the follow-up have also been reported. RESULTS: A total of 115 women with a median age of 53 years were included. The median follow-up duration was 75 months. The 5-year failure rate was 48% (95 CI 46%-57%). Age above 50 years, negative tension-free vaginal tape test and transobturator route were associated with surgical failure. Thirty-six patients (31.3%) underwent at least 1 reoperation for complications or failure, and 2 required definitive intermittent catheterization. CONCLUSIONS: Synthetic mid-urethral slings may be an acceptable alternative to autologous slings or artificial urinary sphincters for the treatment of stress urinary incontinence in a selected group of patients with neurogenic lower urinary tract dysfunction.

OBJECTIVES: The aim of this study was to assess midterm functional outcomes and complications of robot-assisted laparoscopic cystectomy with non-continent urinary diversion in patients with neurogenic lower urinary tract dysfunction. MATERIALS AND METHODS: We performed a retrospective single center study including all patients who underwent robot-assisted laparoscopic cystectomy with non-continent urinary diversion between January 2008 and December 2018 for neurogenic lower urinary tract dysfunction. Perioperative data, early and late complications, reoperation rate, renal function, and patient satisfaction (PGI-I) were evaluated. RESULTS: One hundred and forty patients were included (70 multiple sclerosis, 37 spinal cord injuries, 33 others) with a median follow-up of 29 months (12-49). The main indication for surgery was an inability to perform intermittent self-catheterization (n = 125, 89%). The early complication rate (<30 days) was 41% (n = 58), including 72% (n = 45) minor complications (Clavien I-II) and 29% (n = 17) major complications (Clavien III-V). Three patients died in the early postoperative period. Late complications appear in 41% (n = 57), with 9% (n = 13) being ureteroileal anastomotic stricture. The overall reintervention rate was 19% (n = 27), mainly for lithiasis surgery. Pre- and postoperative renal function were comparable. Most of patients reported an improvement in their quality of life following their surgery (PGI-I 1-2). CONCLUSION: Robot-assisted laparoscopic cystectomy with non-continent urinary diversion may be of particular interest in patients with neurogenic lower urinary tract dysfunction who are unable to benefit from conservative treatment, as it provides midterm protection of the upper urinary tract and an improvement in quality of life.

PURPOSE: Urgent transfers of severely impaired patients with chronic neurological disability (PwND) from a neurological physical and rehabilitation medicine (nPRM) to an intensive care unit (ICU) or an emergency room (ER) served as the basis for this study. We hypothesized that human and structural factors interfered with but were not directly related to the acute context. METHODS: We decided to use a qualitative methodology, based on in-depth interviews with 16 ICU/ER physicians. We used mixed bottom-up and top-down methods. We interpreted our data using a thematic approach based on the key principles of grounded theory, which were modified with consideration of the literature. RESULTS: Three main domains emerged. The impact of the clinical setting notably implied the patient's clinical typology between the acute event and the chronic background, but also bed availability. Key elements of the telephone negotiation were confidence and perceived usefulness of the transfer. Finally, the otherness of some categories of patients, transferred with more difficulty, involved those with cognitive impairment. CONCLUSIONS: The existence of healthcare pathways for many years has created an organizational culture between departments of nPRM and ICUs. But urgent transfers also imply organizational ethics, as a balance should be struck between utility and equity. IMPLICATIONS FOR REHABILITATIONStructural and human factors interfere in urgent transfers, involving the settings within health pathways, the key elements of negotiation to get confidence and a perceived utility of transfer, and certain categories of people, especially those with cognitive impairment.Transfers that imply negotiation between practitioners from physical and rehabilitation medicine and intensive care unit departments, lead to a need of organizational ethics, as a balance should be struck between the principles of utility and equity.The development of facilitating tools such as a commitment charter is of paramount importance as it can support ethical decision-making.

OBJECTIVES: To describe the 3-month prevalence and correlates of self-reported physical health conditions in persons with spinal cord injury (SCI) worldwide. STUDY DESIGN: Multinational cross-sectional survey. SUBJECTS: Community-living persons with traumatic or non-traumatic SCI aged >18 years from 21 countries representing all the 6 World Health Organization regions. METHODS: The study used data from 11,058 participants in the International SCI Community Survey (InSCI). The survey, based on the International Classification of Functioning, Disability and Health (ICF) Core Sets for SCI, was conducted in 2017-19 simultaneously in the participating countries. The health conditions were reported on a modified version of the SCI Secondary Conditions Scale. RESULTS: Overall, 95.8% of the participants reported having experienced 1 or more health problems secondary to SCI. Having pain was the most prevalent problem (77.3%), followed by spasticity/muscle spasms (73.5%) and sexual dysfunction (71.3%), and the least prevalent was respiratory problems (28.8%). The participants reported a mean of 7.4 concurrent health conditions. Unmet healthcare needs, being a smoker, being a female, having a complete lesion, and a traumatic injury exhibited significant associations with comorbidity. CONCLUSION: Physical health problems secondary to SCI are extremely common worldwide and demand investment in appropriate management, medical care and preventative measures.

BACKGROUND: Scientific evidence indicates the presence of secondary conditions (such as pressure injuries) after spinal cord injury (SCI). Treatment methods focusing on the management of paraplegia and tetraplegia include systematic preventive follow-up. These advances have significantly improved the functional and vital prognosis of people with SCI, but some people may not have access to these specialized organizations or may not adhere closely to this medicalized vision. We used a narrative approach to explore the perceptions of people with SCI to better understand their adherence to follow-up. OBJECTIVES: We aimed to determine the "common denominators" that lead to adherence or non-adherence to long-term follow-up after SCI. METHODS: People with SCI who had completed their first rehabilitation period for > 1 year were included with regard to 2 variables: 1) an actual medical follow-up or not and 2) a history of pressure injury or not. A review of the literature was used as preparation for semi-directive interviews, which were prospectively analysed by using qualitative analysis software. Thematic saturation was reached at 28 interviews, and 32 interviews were ultimately completed. RESULT: Three main areas concerning participants' perceptions emerged: people's readiness, appropriation and modulation of the systematic follow-up. We developed a broad conceptual framework representing follow-up and the promotion of the long-term health of people with SCI from their perspectives. CONCLUSIONS: The medical environment should ensure that people with SCI are ready to actively consider the implementation of prevention strategies and should take into account their ability to establish their own truth, to integrate various life stages after SCI and to negotiate systematic follow-up. The implementation of data about functioning should be conducted using the concept of the Learning Health System.

INTRODUCTION AND HYPOTHESIS: The aim of this systematic review of the literature was to pool all the existing data regarding pregnancy and delivery in women with neurogenic bladder or bladder exstrophy who had undergone previous lower urinary tract reconstruction (LUTR). METHODS: We conducted a systematic review of the literature from PubMed/MedLine, ClinicalTrials.gov and the Google Scholar database, from 1972 to July 2020. Fifty articles were included, of which 25 contained data that could be pooled (229 women representing 292 pregnancies). RESULTS: Ninety-eight women had bladder exstrophy (43%), 58 had spinal dysraphism (25%), 14 had spinal cord injury (6%), and 59 presented other pathological conditions. Of these, 138 have had an augmentation cystoplasty (61%), 42 (18%) had a continent cutaneous urinary diversion, and 31 had an artificial urinary sphincter (14%). During their pregnancy, 97 women (33%) experienced at least one febrile urinary tract infection. Thirty-one women (11%) required ureteral stenting or nephrostomy placement for upper urinary tract dilatation. Forty-six pregnancies ended with premature delivery (16%). Delivery mode was by C-section for 108 patients (62%) and vaginal delivery for 104 (36%). Twenty complications were reported during delivery (mainly urological), of which 19 occurred during C-section. Nine women experienced postpartum urinary incontinence (4%); in 5 of then this was due to urinary fistulae secondary to complicated C-section. CONCLUSIONS: Pregnancy and vaginal delivery are possible for women with LUTR who have no obstetric or medical contraindications, except for some particular cases of bladder exstrophy. However, these high-risk pregnancies and deliveries should be managed by a specialist multidisciplinary team.

BACKGROUND: Transanal irrigation (TAI) has emerged as a key option when more conservative bowel management does not help spinal cord injured (SCI) individuals with neurogenic bowel dysfunction (NBD). AIM: To investigate the short-term efficacy and safety of an electronic TAI system (Navina Smart) in subjects with NBD. DESIGN: We present an open, prospective efficacy study on Navina Smart, in individuals with NBD secondary to SCI, studied at three months. POPULATION: Eighty-nine consecutive consenting established SCI individuals (61 male; mean age 48, range 18-77) naïve to TAI treatment were recruited from ten centres in seven countries. Subjects had confirmed NBD of at least moderate severity (NBD score ≥10). METHODS: Subjects were taught how to use the device at baseline assisted by the Navina Smart app, and treatment was tailored during phone calls until optimal TAI regime was achieved. The NBD score was measured at baseline and at three months follow up (mean 98 days). Safety analysis was performed on the complete population while per protocol (PP) analysis was performed on 52 subjects. RESULTS: PP analysis showed a significant decrease in mean NBD score (17.8 to 10, p<0.00001). In subjects with severe symptoms (defined as NBD score ≥14), mean NBD scores decreased (19.4 to 10.9, p<0.0001). The number of subjects with severe symptoms decreased from 41 (79%) subjects at baseline to 16 (31%) at three months follow-up. Device failure accounted for the commonest cause for loss of data. Side effects possibly related to the device developed in 11 subjects (12%). Discontinuation due to failure of therapy to relieve symptoms was reported by 5 subjects (6%). CONCLUSION: Navina Smart is effective for individuals with NBD, even those with severe symptoms; long-term data will follow. Whilst there were some device problems (addressed by the later stages of subject recruitment) the treatment was generally safe. CLINICAL TRIAL: (ClinicalTrials.gov number NCT02979808).

AIMS: To report the long-term functional outcomes of artificial urinary sphincter (AUS) implantation in female patients with spinal dysraphism and stress urinary incontinence (SUI) related to intrinsic sphincter deficiency (ISD). METHODS: The charts of all spina bifida female patients with SUI due to ISD who underwent AUS (AMS 800) implantation between 2005 and 2019 at three academic departments of urology were retrospectively reviewed. Reoperation was defined as either revision or explantation of the AUS device. Reoperation-free survival of the AUS device was estimated using the Kaplan-Meier method. Continence status as per patients' subjective assessment was categorized as follows: complete continence (no pads), improved continence, unchanged SUI or worsened SUI. RESULTS: Twenty-three patients were included, 69.6% were self-catheterizing. The median follow-up was 14 years. Median time to first reoperation was 10 years. Survival rates without reoperation were 85.9%, 41.8%, 34.6%, and 20.9% at 5, 10, 15, 20 years, respectively. Survival rates without AUS explantation were 90.7%, 66.3%, 55.2%, and 41.4% at 5, 10, 15, 20 years, respectively. None of the patients who underwent device explantation had a new AUS implanted. The only predictive factor of reoperation-free survival was the type of spinal dysraphism (hazards ratio = 3.60 for closed vs. open dysraphism; p = .04). At last follow-up, 17 of the 23 patients were fully continent (73.9%). CONCLUSION: AUS in female patients with spina bifida may be associated with satisfactory long-term functional outcomes and a high reoperation rate. The median time to first reoperation was similar to what is reported in the male AUS literature (10 years).

BACKGROUND: The impact of social support on the long-term condition after a spinal cord injury (SCI) varies across studies mainly involving self-report questionnaires. OBJECTIVE: We aimed to establish the common factors associated with social support leading individuals with an SCI to the effective prevention of secondary complications, including via adherence to medical follow-up. METHODS: Inclusion criteria were a history of acquired SCI of any etiology, wheelchair use, and age≥18 years at the time of the study. Participants should have completed their initial rehabilitation program in France≥1 year earlier and were also enrolled according to 2 related study variables: routine medical follow-up (patients were or were not followed up) and the medically supervised reporting of a pressure ulcer after the initial rehabilitation session (0 or≥1 pressure ulcers). We performed a preparatory quantitative and qualitative literature review to identify factors affecting long-term follow-up after SCI, then adopted a narrative design with semi-structured interviews, transcribed and analyzed progressively by using qualitative analysis software. RESULTS: We included 32 participants. We categorized our results based on the knowledge, attitudes, beliefs and practices of participants with respect to pressure ulcer prevention and long-term medical follow-up. Our narrative approach allowed us to identify 3 main domains relevant to social support: reciprocity, self-management and timing related to social support. CONCLUSIONS: Our study showed social support as a dynamic process, a reciprocal phenomenon evolving in variations over time. These findings should be central to short- and long-term therapeutic education programs for patients and for people providing social support. Effective changes should also be implemented through the concept of the Learning Health System.

OBJECTIVE: To provide prevalence estimates for problems in functioning of community-dwelling persons with spinal cord injury (SCI) and to examine associations between various areas of functioning with the purpose of supporting countries in identifying targets for interventions. DESIGN: Cross-sectional survey. SETTING: Community, 22 countries including all World Health Organization regions. PARTICIPANTS: Persons (N=12,591) with traumatic or nontraumatic SCI aged 18 years or older. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: We estimated the prevalence of problems in 53 areas of functioning from the Brief International Classification of Functioning, Disability and Health (ICF) core set for SCI, long-term context, or ICF rehabilitation set covering 4 domains: impairments in body functions, impairments in mental functions, independence in performing activities, and restrictions in participation. Associations between areas of functioning were identified and visualized using conditional independence graphs. RESULTS: Participants had a median age of 52 years, 73% were male, and 63% had paraplegia. Feeling tired, bowel dysfunction, sexual functions, spasticity, pain, carrying out daily routine, doing housework, getting up off the floor from lying on the back, pushing open a heavy door, and standing unsupported had the highest prevalence of problems (>70%). Clustering of associations within the 4 functioning domains was found, with the highest numbers of associations within impairments in mental functions. For the whole International Spinal Cord Injury sample, areas with the highest numbers of associations were circulatory problems, transferring bed-wheelchair, and toileting, while for the World Health Organization European and Western Pacific regions, these were dressing upper body, transferring bed-wheelchair, handling stress, feeling downhearted and depressed, and feeling happy. CONCLUSIONS: In each domain of functioning, high prevalence of problems and high connectivity of areas of functioning were identified. The understanding of problems and the identification of potential targets for intervention can inform decision makers at all levels of the health system aiming to improve the situation of people living with SCI.

The physiopathology of digestive disorders in patients with spinal cord injury (SCI) remains largely unknown, particularly the involvement of the enteric nervous system (ENS). We aimed in a rat model of chronic thoracic SCI to characterize (1) changes in the neurochemical coding of enteric neurons and their putative consequences upon neuromuscular response, and (2) the inflammatory response of the colon. Ex vivo motility of proximal and distal colon segments of SCI and control (CT) rats were studied in an organ chamber in response to electrical field stimulation (EFS) and bethanechol. Immunohistochemical analysis of proximal and distal segments was performed using antibodies again Hu, neuronal nitric oxide synthase, (nNOS), and choline acetyltransferase. Colonic content of acetylcholine and acetylcholinesterase was measured; messenger RNA (mRNA) expression of inflammatory cytokines was measured using reverse transcription quantitative polymerase chain reaction (RT-qPCR) approaches. Compared with the CT rats, the contractile response to bethanechol was significantly decreased in the proximal colon of SCI rats but not in the distal colon. The proportion of nNOS immunoreactive (IR) neurons was significantly reduced in the proximal but not distal colon of SCI rats. No change in proportion of choline acetyltransferase (ChAT)-IR was reported; the tissue concentration of acetylcholine was significantly decreased in the proximal colon of SCI rats. The expression of tumor necrosis factor alpha (TNF-α) and intercellular adhesion molecule-1 (ICAM-1) was significantly reduced in the proximal and distal colon of SCI rats. This study demonstrates that functional motor and enteric neuroplastic changes affect preferentially the proximal colon compared with the distal colon. The underlying mechanisms and factors responsible for these changes remain to be discovered.
RESUMEN
BACKGROUND: Recurrent urinary tract infections (R-UTIs) are the main cause of morbidity and hospitalizations in subjects with neurogenic bladder (NB) due to spinal cord injury (SCI). We evaluated the efficacy of weekly oral cyclic antibiotic (WOCA) prophylaxis (ie, the alternate weekly administration of 2 antibiotics) in preventing R-UTIs. METHODS: Randomized (1:1), open-label, superiority-controlled trial compared WOCA prophylaxis to no prophylaxis (control) for 6 months in patients with NB due to SCI, using clean intermittent self-catheterization, and suffering from R-UTIs. Primary outcome was incidence of symptomatic antibiotic-treated UTIs. Secondary outcomes were number of febrile UTIs, number of hospitalizations, WOCA tolerance, antibiotic consumption, number of negative urine cultures, and emergence of bacterial resistance in urinary, intestinal, and nasal microbiota. RESULTS: Forty-five patients were either allocated to the WOCA group (n = 23) or the control group (n = 22). Median (IQR) incidence of symptomatic antibiotic-treated UTIs was 1.0 (0.5-2.5) in the WOCA group versus 2.5 (1.2-4.0) (P = .0241) in the control group. No febrile UTIs were recorded in the WOCA group versus 9 (45.0%) (P < .001) in the control group. The median number of additional antibiotic treatment was 0.0 (IQR, 0.0-2.0) versus 3.0 (2.0-5.0) (P = .004) in the WOCA and control groups, respectively. Only few adverse events were reported. No impact on emergence of bacterial resistance was observed. CONCLUSIONS: WOCA is efficient and well tolerated in preventing R-UTIs in SCI patients. In our study, we did not observe any emergence of antibiotic resistance in digestive and nasal microbiological cultures. CLINICAL TRIALS REGISTRATION: NCT01388413.

BACKGROUND: The pronator teres and pronator quadratus muscles are frequently injected with neuromuscular blocking agents to improve supination in children with spastic cerebral palsy and limited active elbow supination. However, determining by simple clinical examination whether these muscles are overactive during active movement is difficult. OBJECTIVE: This study aimed to develop a semi-automatic method to detect pronator muscle overactivity by using surface electromyography (EMG) during active supination movements in children with cerebral palsy. METHODS: In total, 25 children with unilateral spastic cerebral palsy (10 males; mean [SD] age 10.6 [3.0] years) and 12 typically developing children (7 males; mean age 11.0 [3.0] years) performed pronation-supination movements at 0.50Hz. Kinematic parameters and surface EMG signals were recorded for both pronator muscles. Three experts visually assessed muscle overactivity in the EMG signals of the children with cerebral palsy, in comparison with the reference group. The reliability and discrimination ability of the visual assessments were analysed. Overactivity detection thresholds for the semi-automatic method were adjusted by using the visual assessment by the EMG experts. The positive and negative predictive values of the semi-automatic detection method were calculated. RESULTS: Intra-rater reliability of visual assessment by EMG experts was excellent and inter-rater reliability was moderate. For the 25 children with unilateral spastic cerebral palsy, EMG experts could discriminate different profiles of pronator overactivity during active supination: no pronator overactivity, one overactive pronator, or overactivity of both pronators. The positive and negative predictive values were 96% and 91%, respectively, for this semi-automatic detection method. CONCLUSIONS: Detection of pronator overactivity by using surface EMG provides an important complement to the clinical examination. This method can be used clinically, with the condition that clinicians be aware of surface EMG limitations. We believe use of this method can increase the accuracy of treatment for muscle overactivity, resulting in improved motor function and no worsening of paresis.

To compare the neurological evolution, functional improvement, and outcomes after acute hospitalization for elderly patients with newly non-traumatic (NTSCI) and traumatic (TSCI) spinal cord injury. Retrospective single-center study conducted with a cohort of patients older than 70 years old with NTSCI and TSCI, admitted between January 2004 and December 2014.in a Rehabilitation center in Nantes France. One hundred and ten patients were included (43 TSCI and 67 NTSCI). Most of the NTSCI had incomplete paraplegia (p<0.001) whereas TSCI had incomplete tetraplegia (p=0.002). Falls were the main cause of traumatic injury. NTSCI and paraplegia had a favourable neurological improvement (p=0.14 and 0.02) whereas TSCI and tetraplegia remained stable (p=0.13 and p=0.007). Therefore functional status remained stable for almost half the patients. Sixty percent of the patient get an assistance or were independent in Katz ADL Index assessment, mostly were NTSCI and paraplegic (p=0.17 and 0.40). About 44% of the patients had normal micturition at discharge, they all had incomplete lesion. Fifteen patients used intermittent catheterization, most of them were TSCI (p=0.02). Private residence was the first place of residence after discharge (47%), 17% goes in nursing home residence. NTSCI were more likely to go home at discharge (p=0.07), to have less comorbidities (p=0.08), length of stay shorter (p=0.053) and a mean age at death higher (p=0.01). Twenty-six percent of the patient deceased, mostly by respiratory problem. The etiology of the lesion and level of neurological impairment influence the neurological evolution, functional improvement and the outcomes of elderly patient with newly SCI. Rehabilitation of elderly SCI must be adapted to enhance neurological and functional recovery.

OBJECTIVE: To evaluate the clinical efficacy, urodynamic effect and safety of Botulinum Toxin A (BTXA) injections after failure of augmentation enterocystoplasty (AE) performed for neurogenic detrusor overactivity. PATIENTS AND METHODS: We performed a multicenter retrospective study that included patients who had AE and at least one injection of BTXA after AE in 15 GENULF (French Speaking Neuro-Urology Study Group) centers. Clinical and urodynamic data were collected from medical files according to a standardized questionnaire and colligated in an anonymous database. RESULTS: Thirty-three patients with an injection of BTXA after AC in 9 out of 15 centers were included. Mean age at the time of AE was 24 ± 15 years. Overall efficacy (defined by clinical efficacy associated with a request by the patient for reinjection) was observed in 58% of the patients. Mean maximum cystomanometric capacity increased by 28% (333 ± 145 vs 426 ± 131 mL; Pâ¯=â¯.007) and maximum detrusor pressure (Pdet max) decreased by 43% (44 ± 37 vs 25 ± 18 cm H2O; Pâ¯=â¯.02) after BTXA. Only one side effect was recorded out of the 152 procedures (transient generalized muscle weakness without respiratory distress). CONCLUSION: In patients with failure after AE performed for neurogenic detrusor overactivity, injection of BTXA in the enlarged bladder was effective in over half of the cases with low morbidity. If this therapeutic approach were confirmed, it could be proposed as an alternative to AE surgical revision.

Spinal cord injury (SCI) is a major cause of severe disability. This study aims to assess the effectiveness of a quality improvement program on neurological recovery after SCI. Before-after study during two phases was done in one intensive care unit in a university hospital. The quality improvement project comprised protective mechanical ventilation, early tracheostomy in anatomical injury above the sixth cervical vertebra, early enteral nutrition, early mobilization, and active perineal care in adult SCI patients. The primary endpoint was the difference between the American Spinal Injury Association (ASIA) motor score between discharge and intensive care unit (ICU) admission (Delta ASIA). Fifty-seven and 60 patients were included in the control and in the intervention period respectively. The ASIA motor score upon ICU admission was 16 (7-37) before and 11 (2-30) after the implementation (p = 0.30). The implementation phase was associated with lower tidal volumes (p < 0.001), higher positive end-expiratory pressure (p < 0.001), earlier tracheostomy (p = 0.01), earlier enteral nutrition initiation (p < 0.05), earlier mobilization (p < 0.05), and more active perineal care (p < 0.05). The Delta ASIA was +16 [4-32] after versus +6 [0-14] before the intervention (p < 0.05). After adjustment for potential cofounders, the intervention phase was significantly associated with higher Delta ASIA (ß coefficient, 11.4; CI95 [1.9-21]; p = 0.01) in multi-variable analysis. No secular time trend unrelated to the intervention was highlighted. One year after trauma, the Delta ASIA was higher in the intervention period than in the control period (+34 [15-60] vs. +11 [0-33]; p < 0.05). After adjustment on potential confounders, an early in-ICU rehabilitation program in SCI patients was associated with higher neurological score upon ICU discharge.
