Abstract
AIM The objective of this study was to evaluate the safety and efficacy of a novel technique of formal reduction and circumferential fusion for pediatric high-grade spondylolisthesis (HGS). PURPOSE The safety and efficacy of formal reduction for high-grade spondylolisthesis (HGS) has never been thoroughly examined. This study reports the outcomes of 29 children with HGS who underwent a procedure of gradual reduction and circumferential fusion. METHODS 29 children (13 males, 16 females) were recruited between 2006 and 2010. Radiographic measurements (including % of slip, lumbosacral angle-LSA, pelvic incidence-PI, pelvic tilt-PT, sacral slope-SS, and proximal femoral angle-PFA) and quality of life assessment (SRS-22 questionnaire) were prospectively obtained at baseline and at the last post-operative follow-up (> 2 years post-op). Radiological measurements were used to classify patients according to the Spine Deformity Study Group (SDSG) classification. RESULTS Mean baseline slip % was 69.9 ± 16.5%. There were 13 patients with a balanced pelvic (SDSG Type 4) and 16 with an unbalanced pelvis (SDSG Type 5 and 6). On average, a reduction of 45.5 ± 15.3% (range 20-86%) was achieved safely with no major complication. In particular, of the 29 patients, only 3 had a L5 radiculopathy postoperatively that was self-resolved at follow-up. From a radiological standpoint, we observed a mean improvement of LSA from 80.3 ± 17.9° to 91.7 ± 13.6°. We also observed a statistically significant improvement in global HRQOL, and in the function and body image domains. CONCLUSION This prospective study suggests that formal reduction of HGS followed by circumferential fusion is safe when using a standardized surgical technique based on gradual reduction. Performing this intervention could also help improve QOL in some patients.

Abstract
OBJECTIVE The aim of the study is to determine what improvement on the American Spinal Injury Impairment Scale correlates with functional status after a traumatic spinal cord injury. DESIGN We performed an observational cohort study, analyzing prospective data from 168 patients with traumatic spinal cord injury admitted to a single level 1 trauma center. A multivariable analysis was performed to assess the relationship between functional status (from the Spinal Cord Independence Measure) at 1-year follow-up and American Spinal Injury Impairment Scale grade (baseline and 1-yr follow-up), while taking into account covariables describing the sociodemographic status, trauma severity, and level of neurological injury. RESULTS Individuals improving to at least American Spinal Injury Impairment Scale grade D had significantly higher Spinal Cord Independence Measure score compared with those not reaching American Spinal Injury Impairment Scale D (89.3 ± 15.2 vs. 52.1 ± 20.4) and were more likely to reach functional independence (68.5% vs. 3.6%), regardless of the baseline American Spinal Injury Impairment Scale grade. Higher final Spinal Cord Independence Measure was more likely with an initial American Spinal Injury Impairment Scale grade D (β = 1.504; 95% confidence interval = 0.46-2.55), and a final American Spinal Injury Impairment Scale grade D (β = 3.716; 95% CI = 2.77-4.66) or E (β = 4.422; 95% CI = 2.91-5.93). CONCLUSIONS Our results suggest that reaching American Spinal Injury Impairment Scale grade D or better 1 yr after traumatic spinal cord injury is highly predictive of significant functional recovery, more so than the actual improvement in American Spinal Injury Impairment Scale grade from the injury to the 1-yr follow-up.

Abstract
CONTEXT Activity-based therapy initiated within days of the accident could prevent complications and improve neurofunctional outcomes in patients with traumatic spinal cord injury (TSCI). However, it has never been attempted in humans with TSCI because of practical obstacles and potential safety concerns. The PROMPT-SCI trial is the first attempt at implementing ABT within the first days following a TSCI (i.e. very early ABT; VE-ABT). The objective is to determine if VE-ABT can be initiated safely in the intensive care unit (ICU) within 48 h of early decompressive surgery. DESIGN As part of the PROMPT-SCI trial, 15 adult patients with severe TSCI were enrolled between April and November of 2021. The intervention consisted of 30-minute sessions of motor-assisted in-bed leg cycling starting within 48 h of early spinal surgery. Safety was assessed through continuous monitoring of vital signs and recording of adverse events during and after sessions. The main outcome measure was the achievement (yes or no) of a full and safe session within 48 h of early surgery. FINDINGS Out of the 15 participants, 10 (66.6%) achieved this outcome. Out of the remaining 5, 2 were not cleared to engage in cycling within 48 h of surgery and 3 initiated cycling within 48 h but stopped prematurely. All 5 eventually completed a full and safe session within the next 1-2 days. In all 15 participants, there were no neurological deteriorations after the first completed session. CONCLUSION Our results suggest that it is safe and feasible to perform a first session of VE-ABT within days of a severe TSCI with no serious adverse events and excellent completion rates.

Abstract
Climate change is impacting agriculture in many ways, and a contribution from all is required to reduce the imminent losses related to it. Recently, it has been shown that citizen science could be a way to trace the impact of climate change. However, how can citizen science be applied in plant pathology? Here, using as an example a decade of phytoplasma-related diseases reported by growers, agronomists, and citizens in general, and confirmed by a government laboratory, we explored how to better value plant pathogen monitoring data. Through this collaboration, we found that in the last decade, 34 hosts have been affected by phytoplasmas; 9, 13, and 5 of these plants were, for the first time, reported phytoplasma hosts in eastern Canada, all of Canada, and worldwide, respectively. Another finding of great impact is the first report of a 'Candidatus Phytoplasma phoenicium'-related strain in Canada, while 'Ca. P. pruni' and 'Ca. P. pyri' were reported for the first time in eastern Canada. These findings will have a great impact on the management of phytoplasmas and their insect vectors. Using these insect-vectored bacterial pathogens, we show the need for new strategies that can allow fast and accurate communication between concerned citizens and those institutions confirming their observations.[Formula: see text] Copyright © 2023 The Author(s).

Abstract
The taxonomic assignment of sequences obtained by high throughput amplicon sequencing poses a limitation for various applications in the biomedical, environmental, and agricultural fields. Identifications are constrained by the length of the obtained sequences and the computational processes employed to efficiently assign taxonomy. Arriving at a consensus is often preferable to uncertain identification for ecological purposes. To address this issue, a new tool called "ASVmaker" has been developed to facilitate the creation of custom databases, thereby enhancing the precision of specific identifications. ASVmaker is specifically designed to generate reference databases for allocating amplicon sequencing data. It uses publicly available reference data and generates specific sequences derived from the primers used to create amplicon sequencing libraries. This versatile tool can complete taxonomic assignments performed with pre-trained classifiers from the SILVA and UNITE databases. Moreover, it enables the generation of comprehensive reference databases for specific genes in cases where no directly applicable database exists for taxonomic classification tools.

Abstract
STUDY DESIGN Retrospective validation protocol. OBJECTIVE The International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) is the most comprehensive tool for classifying spinal cord injuries (SCI), but it is not adapted for the evaluation of trauma patients. The objective is to develop and validate a streamlined tool, the Montreal Acute Classification of Spinal Cord Injury (MAC-SCI) that can be integrated in the evaluation of trauma patients to detect and characterize traumatic SCI (tSCI). METHODS The completion rate of the ISCNSCI during initial evaluation after tSCI was estimated at a Level-1 trauma center specialized in SCI care. Using a modified Delphi technique, we designed the MAC-SCI, a new tool to detect and characterize the severity grade and level of SCI in the polytrauma patient. A cohort consisting of 35 consecutive tSCI patients with complete ISNCSCI documentation was used to validate the MAC-SCI. The severity grade and neurological level of injury (NLI) were assessed using the MAC-SCI, and compared to those obtained with the ISNCSCI. RESULTS Only 33% of 148 patients admitted after a tSCI had a complete ISNCSCI performed at initial presentation. The MAC-SCI retains 53 of the 134 elements from the ISNCSCI. There was a 100% concordance in severity grade between the MAC-SCI and ISNCSCI. The NLI were within 2 levels between the MAC-SCI and ISNCSI for 100% of patients. CONCLUSION The MAC-SCI is a streamlined tool that accurately detects and characterizes tSCI in the acute trauma setting. It could be implemented in trauma protocols to guide the management of SCI patients. LEVEL OF EVIDENCE Level III Diagnostic criteria.

Abstract
CONTEXT/OBJECTIVE Providing accurate counseling on neurological recovery is crucial after traumatic spinal cord injury (TSCI). The early neurological changes that occur in the subacute phase of the injury (i.e. within 14 days of early decompressive surgery) have never been documented. The objective of this study was to assess peri-operative neurological improvements after acute TSCI and determine their relationship with long-term neurological outcomes, measured 6-12 months following the injury. METHODS A retrospective cohort study of 142 adult TSCI patients was conducted. Early peri-operative improvement was defined as improvement of at least 1 AIS grade between the pre-operative and follow-up (6-12 months post-TSCI) assessment. neurological improvement of at least 1 AIS grade. RESULTS Out of the 142 patients, 18 achieved a peri-operative improvement of at least 1 AIS grade. Presenting a pre-operative AIS grade B and having shorter surgical delays were the main factors associated with stronger odds of achieving this outcome. Out of the 140 patients who still had potential for improvement at the time of the post-operative assessment, 44 achieved late neurological recovery (improvement of at least 1 AIS grade between the post-operative assessment and follow-up). Patients who presented a perioperative improvement seemed more likely to achieve later neurological improvement as well, although this was not statistically significant. CONCLUSION Our results suggest that it is important to assess early perioperative neurological changes within 14 days of surgery because it can provide beneficial insight on long-term neurological outcomes for some patients. In addition, earlier surgery may promote early neurological recovery.

Abstract
CONTEXT/OBJECTIVE Functional motor-incomplete AIS-D traumatic spinal cord injury (tSCI) represents an important growing population in neuro-traumatology. There is thus an important need for establishing strategies to optimize SCI rehabilitation resources. This study aims at proposing eligibility criteria to select individuals who could be discharged home (home-based rehabilitation) after acute care following an AIS-D tSCI and investigate its impact on the long-term functional status and quality of life (QOL), as compared to transfer to inpatient functional rehabilitation (IFR) resources. DESIGN An observational prospective cohort study. SETTING A single Level-1 specialized trauma center. PARTICIPANTS 213 individuals sustaining an AIS-D tSCI. INTERVENTIONS Home-based rehabilitation based on clinical specific criteria to be assessed by the acute care team. OUTCOME MEASURES Functional status and QOL as assessed by the Spinal Cord Independence Measure version 3 and WHOQOL-BREF questionnaire one year following the injury, respectively. RESULTS A total 37.9% of individuals fulfilled proposed criteria for home-based rehabilitation after acute care. As expected, this group was significantly younger, experienced lesser comorbidities and acute complications, and showed higher motor and sensory function compared to the IFR group. Home-rehabilitation was associated with a higher long-term functional status, physical and psychological QOL, when accounting for relevant confounding factors after an acute AIS-D tSCI. There was no readmission due to failure of home-based rehabilitation. CONCLUSION Home-based rehabilitation in selected individuals sustaining an acute AIS-D tSCI is a safe and interesting strategy to optimize the long-term outcome in terms of functional recovery, physical and psychological QOL, as well as to optimize inpatient rehabilitation resources. The proposed eligibility criteria can be used by the acute care team to select the optimal discharge orientation in this important subpopulation.

Abstract
Alstroemeria necrotic streak virus (ANSV) is an Orthotospovirus that has been isolated from symptomatic Alstroemeria plant in 2010 (Hassani-Mehraban et al. 2010). It has been shown to infect crops of bell pepper (Capsicum annuum) and tomato (Solanum lycopersicum) (Olaya et al. 2017) which are two of the three biggest greenhouse crops in Canada in terms of production volume and value (Statistic Canada. 2020). In July of 2022, the entire production of bell pepper (all plants) from a greenhouse in Québec was presenting necrotic rings and discoloration in fruit and seemingly healthy leaves. Samples from these infected bell pepper were found to be negative for twenty two common viruses infecting bell pepper by ELISA immunoassay by the Laboratoire d'expertise et de diagnostic en phytoprotection (LEDP) (Québec, Canada). To identify the causal agent, double-stranded RNA was extracted from leaf and fruit of one plant to form two separate samples (leaf and fruit) and used for cDNA library preparations with Nextera XT DNA Sample Prep kit (Illumina, USA). The libraries were sequenced using Illumina Miseq (Fall et al. 2020). The same dsRNA were also sequenced with MinION nanopore sequencing method as described previously (Javaran et al. 2021; Javaran et al. 2023). The obtained raw FASTQ data were processed following the methodology described in Fall et al. 2020 and Javaran et al. 2023. The Miseq sequencing yielded over 2 million reads per sample with a percentage of mapped viral reads ranging from 26.92 to 47.29% of the total number of reads. The leaf samples were positive to Bell pepper endornavirus (BPEV) with the full genome covered 16713 times and Alstroemeria necrotic streak virus (ANSV) with 98% of the genome covered 4929 times. The MinION sequencing yielded 1,028,460 reads and the same viruses were detected with 1288 long reads (mean length of 745bp) assigned to ANSV genome. Both viruses were detected in the leaf and fruit samples. The complete ANSV genome comprising three segments (L, M, and S) was assembled and deposited in GenBank: (OQ261731-OQ261733). These L, M and S segments shown 99% nt identity with an isolate from the Columbia (GenBank: MF469036, MF469037, MF469038). It is interesting that read coverage at near the 2000th position of the S segment, was very low. This phenomenon may suggest a cleavage site nearby by a viral or host factor. ANSV was mainly found in leaf samples and very low numbers of reads in fruit samples. The presence of ANSV was confirmed by RT-PCR using the primers specific to the ANSV nucleocapsid gene Tospo_S_F (5'- CAG AAT CAG GCT GCA TTT AAT TTC C-3') and Tospo_S_R (5'-CAA CGC TTC CTT TAG CAT TAG G-3') (Gallo et al. 2019). The sequences of ∼600 bp amplicons were determined using Sanger sequencing and showed 100% nt identity with Miseq-derived sequences of ANSV. The virus has previously been detected in Colombia (Hassani-Mehraban et al. 2010) and then in California in 2018 (Tian et al. 2020). This is to our knowledge the first detection of ANSV in Canada. Bell pepper is one of the most important crops in Canada and the ANSV vector, the western flower thrips (Frankliniella occidentalis), known to spread the tomato spotted wilt virus (TSWV) is established in Canada (Allen et al. 1986). The detection of ANSV in Canada is line with the hypothesis of an international spread of this virus (Tian et al. 2020) as is it not known to spread through seeds.

Abstract
CONTEXT Following spinal cord injury (SCI), early spasms are associated with decreased functional recovery. It has also been hypothesized that early spasticity might sign underlying maladaptive neuroplasticity, which could translate in worse neurological outcomes. OBJECTIVE In this context, this paper aims to evaluate if early-onset spasms are also associated with neurological outcomes after SCI. METHODS A retrospective review of 196 cases from a prospective SCI database was conducted. The presence of early spasms during the acute hospitalization was assessed by a single physiatrist. The characteristics and long-term neurological outcomes of individuals with and without early spasms were first compared. Multivariate regression analyses were then performed to determine the relationship between early spasms and neurological outcomes. RESULTS 30.1% (N = 59) of patients presented early spasms. These patients had several distinguishing characteristics including higher odds of tetraplegia (vs. paraplegia) and more severe injuries. At the bivariate level, patients with early spasms had higher odds of improving at least 1 AIS grade between baseline and follow-up. However, this was not significant at the multivariate level. CONCLUSIONS Early spasms are not significantly associated with poorer neurological outcomes, contrasting with the unwritten consensus that early spasticity translates maladaptive neuroplasticity.

Abstract
Rationale: Deep brain stimulation (DBS) of several sites, such as the thalamus, has been shown to reduce seizure frequency and interictal epileptiform activity in patients with refractory epilepsy. Recent findings have demonstrated that the insula is part of the ‘rich club’ of highly connected brain regions. This pilot study investigated short-term effects of high-frequency (HF) insular DBS on interictal epileptiform discharge (IED) rate in patients with refractory epilepsy. Methods: Six patients with drug-resistant epilepsy undergoing an intracranial electroencephalographic study received two sets of 10 min continuous 150 Hz HF-DBS of the insula. For each patient, epileptiform activity was analyzed for a total of 80 min, starting 20 min prior to stimulation set 1 (S1), and ending 20 min after stimulation set 2 (S2). All IEDs were identified and classified according to their anatomic localization by a board-certified epileptologist. The IED rate during the 20 min preceding S1 served as a baseline for comparison with IED rate during S1, S2 and post-stimulation periods. Results: HF-DBS of the anterior insula (aINS) was performed in a patient with an aINS epileptic focus (patient 1). HF-DBS of the posterior insula (pINS) was performed in two patients with a pINS epileptic focus (patients 2 and 4), in one patient with an aINS focus (patient 3), and in two non-insular patients (patients 5 and 6). The total IED (irrespective of their location) rate significantly decreased (p < 0.01) in two patients (patients 1 and 2) during the stimulation period, whereas it significantly increased (p < 0.01) in one patient (patient 6); there was no change in the other three patients. Looking at subsets of spike localization, HF-DBS of the aINS significantly reduced aINS and orbitofrontal IEDs in patient 1 (p < 0.01), while HF-DBS of the pINS had an effect on pINS IEDs (p < 0.01) in both patients with a pINS focus; there was no significant effect of HF-DBS of the insula on IEDs in temporal or other frontal regions. Conclusion: Short-term HF-DBS of the insula had heterogeneous effects on the IED rate. Further work is required to examine factors underlying these heterogeneous effects, such as stimulation frequency, location of IEDs and subregions of the insula stimulated.

Abstract
Previous studies suggest that health-related quality of life (HRQoL) is impaired after a traumatic spinal cord injury (TSCI) and may be worse with older age. This study determines whether the expectations to achieve normal HRQoL in Canadians following a TSCI is indeed influenced by older age. A prospective observational study was conducted on adult patients admitted acutely at a single level-1 trauma center after a TSCI. We assessed HRQoL using the SF-36 physical and mental component summary (PCS and MCS) scores obtained one year post injury. Using Canadian normative HRQoL data matched for age and sex, we defined normal PCS and MCS as a score within 2 standard deviations with respect to the normative Canadian mean. We then conducted logistic regression models to determine the relationship between age at the time of injury and the likelihood of achieving normal PCS and MCS, while controlling for confounding variables. Overall, 39.3% of individuals displayed normal PCS, whereas 80.4% displayed normal MCS. When adjusted for confounders, older age remained significantly associated with increased likelihood of achieving normal PCS (Odds Ratio: 1.03; 95% Confidence Interval: 1.01-1.06; P=0.002). We observed no association between age and achieving normal MCS. A significant proportion of individuals can achieve a normal HRQoL similar to their healthy peers following a TSCI, particularly for the mental component. When compared to younger individuals, older individuals are more likely to achieve normal PCS and present a similar likelihood for achieving normal MCS.

Abstract
INTRODUCTION Activity-based therapy (ABT) is an important aspect of rehabilitation following traumatic spinal cord injury (SCI). Unfortunately, it has never been adapted to acute care despite compelling preclinical evidence showing that it is safe and effective for promoting neurological recovery when started within days after SCI. This article provides the protocol for a study that will determine the feasibility and explore potential benefits of early ABT in the form of in-bed leg cycling initiated within 48 hours after the end of spinal surgery for SCI. METHODS AND ANALYSIS PROMPT-SCI (protocol for rapid onset of mobilisation in patients with traumatic SCI) is a single-site single-arm proof-of-concept trial. Forty-five patients aged 18 years or older with a severe traumatic SCI (American Spinal Injury Association Impairment Scale grade A, B or C) from C0 to L2 undergoing spinal surgery within 48 hours of the injury will be included. Participants will receive daily 30 min continuous sessions of in-bed leg cycling for 14 consecutive days, initiated within 48 hours of the end of spinal surgery. The feasibility outcomes are: (1) absence of serious adverse events associated with cycling, (2) completion of 1 full session within 48 hours of spinal surgery for 90% of participants and (3) completion of 11 sessions for 80% of participants. Patient outcomes 6 weeks and 6 months after the injury will be measured using neurofunctional assessments, quality of life questionnaires and inpatient length of stay. Feasibility and patient outcomes will be analysed with descriptive statistics. Patient outcomes will also be compared with a matched historical cohort that has not undergone in-bed cycling using McNemar and Student's t-tests for binary and continuous outcomes, respectively. ETHICS AND DISSEMINATION PROMPT-SCI is approved by the Research Ethics Board of the CIUSSS NIM. Recruitment began in April 2021. Dissemination strategies include publications in scientific journals and presentations at conferences. TRIAL REGISTRATION NUMBER NCT04699474.

Abstract
OBJECTIVES Little is known about cardiac hemodynamics in the fetus with transposition of the great arteries and intact ventricular septum (TGA-IVS). Better understanding of the fetal physiology in TGA-IVS would help to provide insights into specific clinical complications observed after birth, in particular neonatal hypoxia and pulmonary hypertension. The aim of this study was to assess cardiac hemodynamics in fetuses with TGA-IVS by performing systematic longitudinal echocardiographic follow-up from diagnosis to delivery. METHODS This was a longitudinal retrospective study of fetuses referred between 2010 and 2018 to the Sainte-Justine University Hospital Centre. Complete assessment of cardiac hemodynamics was performed in fetuses with TGA-IVS at 18-22, 28-32 and 35-38 weeks' gestation, which were compared with normal fetuses matched for gestational age. The maximum diameter of the foramen ovale was measured using two-dimensional echocardiography under the guidance of color Doppler echocardiography. Fetal cardiac hemodynamics were analyzed according to postnatal preductal transcutaneous oxygen saturation (TcSO2 ) < 65% or ≥ 65%, as a neonatal outcome, in fetuses with TGA-IVS. RESULTS In total, 59 fetuses with TGA-IVS and 160 normal fetuses were included. Global cardiac output was significantly higher in fetuses with TGA-IVS than in controls, mainly owing to higher global pulmonary output, while global systemic cardiac output did not differ between TGA-IVS fetuses and controls throughout pregnancy. Aortic flow (right ventricular output in fetuses with TGA-IVS, left ventricular output in controls) was significantly higher in fetuses with TGA-IVS than in normal fetuses. Ductal flow was significantly lower in fetuses with TGA-IVS at every timepoint, and this difference increased considerably after 28-32 weeks. In parallel, the diameter of the foramen ovale was significantly smaller in fetuses with TGA-IVS at 28-32 and 35-38 weeks, with a stagnation in growth after 28 weeks, compared with continuous growth in normal fetuses. Most of these cardiac hemodynamic anomalies in fetuses with TGA-IVS were already present at 18-22 weeks, and the differences became greater at 28-32 weeks' gestation. TGA-IVS neonates with TcSO2 < 65% had lower fetal left ventricular output, higher diastolic ductal retrograde flow and smaller foramen ovale at 28-32 weeks, compared with fetal values in those with postnatal TcSO2 ≥ 65%. CONCLUSIONS Compared with normal fetuses, those with TGA-IVS undergo a complex redistribution of blood flow during the second half of pregnancy, with higher global pulmonary flow, lower ductal flow (with negative diastolic flow at the end of pregnancy) and a smaller foramen ovale. In addition, fetal cardiac hemodynamic anomalies observed at 28-32 weeks' gestation were associated with lower postnatal TcSO2 . These observations may provide a better understanding of premature closure of the foramen ovale and postnatal hypoxia that are specific to TGA-IVS physiology. © 2019 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Bladder dysfunction is widespread following traumatic spinal cord injury (TSCI). Early diagnosis of bladder dysfunction is crucial in preventing complications, determining prognosis, and planning rehabilitation. We aim to suggest the first clinical protocol specifically designed to evaluate and manage bladder dysfunction in TSCI patients during acute care. A retrospective cohort study was conducted on 101 patients admitted for an acute TSCI between C1 and T12. Following spinal surgery, presence of voluntary anal contraction (VAC) was used as a criterion for removal of indwelling catheter and initiating trial of void (TOV). Absence of bladder dysfunction was determined from three consecutive post-void bladder scan residuals ≤200 mL without incontinence. All patients were reassessed 3 months post-injury using the Spinal Cord Independence Measure (SCIM). A total of 74.3% were diagnosed with bladder dysfunction during acute care, while 57.4% had a motor-complete TSCI. Three months later, 94.7% of them reported impaired bladder function. None of the patients discharged from acute care after a functional bladder was diagnosed reported impaired bladder function at the 3-month follow-up. A total of 95.7% patients without VAC had persisting impaired bladder function at follow-up. The proposed protocol is specifically adapted to the dynamic nature of neurogenic bladder function following TSCI. The assessment of VAC into the protocol provides major insight on the potential for reaching adequate bladder function during the subacute phase. Conducting TOV using bladder scan residuals in patients with VAC is a non-invasive and easy method to discriminate between a functional and an impaired bladder following acute TSCI.

Abstract
STUDY DESIGN Retrospective review of data from a prospective database of a Level 1 trauma center. OBJECTIVES This project aims to identify factors collected during the acute and rehabilitative care following a traumatic spinal cord injury (TSCI) associated with success and failure to return home after inpatient intensive functional rehabilitation (IFR). SETTING Level 1 trauma center specialized in TSCI care in Montreal, Canada. METHODS All eligible patients from our prospective database were separated into two groups according to discharge destination following IFR. Clinical variables collected during the acute and rehabilitative care as well as demographic variables were compared between patients who managed to return home (Group 1) and those who were discharged elsewhere (Group 2). Multivariable regression analyses were conducted with variables that were significant at the univariate level. RESULTS Out of the 193 patients included, 22 (11%) failed to return home following IFR. Six variables were associated with failure to return home at the univariate level: longer acute length of stay (LOS), longer rehabilitation LOS, living alone, higher neurological level of injury, having comorbidities, and having a pressure injury (PI) during acute care. Three variables remained significant at the multivariate level: living alone, increasing acute LOS and presenting a high cervical (C1-C4) neurological level of injury. CONCLUSIONS It is important that acute care clinicians recognize the aforementioned factors early after TSCI in order to optimize patients for community reintegration.

Abstract
This evaluation of the integrated Stepping Stones (SS) Teaching Certificate program, including its instructional development (workshops) and theory review (journal club) components, will inform further program development. Results of this project will also add to the limited amount of scholarly work in the area of faculty development program evaluation.
Faculty development literature in the area of organized program assessment reveals use of either quantitative OR qualitative methods. In this project, a novel method combining both techniques was used to explore program impact. Participants completed 2 questionnaires to identify skill-set knowledge gaps in teaching effectiveness. Pre- and post-program quantitative gaps were generated. Focus groups were used for qualitative exploration. Areas explored pre-program included: a) motives for enrollment, b) program expectations and c) prior teaching preparation. Post-program discussion explored: the impact of the program on a) participant’s perceived gaps, b) teaching behaviour change, and c) its influence on their career in education.
We believed the program’s interprofessional environment would foster development of a learning community having impact on faculty knowledge, skills and attitudes related to teaching, and potentially elicit behavioural change in teaching practices. Results from a 2004-2005 cohort of participants have identified a variety of benefits for faculty and their teaching practice. Results from a second separate cohort, 2005-2006 participants, validated the initial findings. Remarkable harmonization in the results of the qualitative analysis between the two cohort samples was evident. Statistically significant differences (p < 0.05) were found in each of the domains examined qualitatively.
Both qualitative and quantitatively, program effectiveness was demonstrated immediately following completion of the program. Follow up to assess the sustainability of the effects is ongoing. The analysis of the quantitative discrepancy (gaps) data has lead to a possible technique to assist in identifying unperceived educational needs.

Abstract
In Wegener's granulomatosis (WG), when the endogenous Proteinase 3 (PR3) of myeloid cells is translocated to the cell surface, a pathologically consequent interaction is believed to occur with classic anti-neutrophil cytoplasmic antibody (cANCA). In contrast, the exact origin of surface PR3 on cells of nonmyeloid origin is still debated. By various methods, PR3 mRNA and protein are easily demonstrated in myeloid cells but not in nonmyeloid cells. Exceptionally, the endothelial ECV304 cell line spontaneously produced PR3 mRNA but no PR3 protein. In the other nonmyeloid cells, we could not show cell surface PR3 either spontaneously or after TNFalpha stimulation. On the other hand, under serum-free conditions and using [(3)H]DFP-labeled HL-60 extract, a rapid, dose-dependent, saturable binding was demonstrated to both myeloid and nonmyeloid cells. That was reproduced with purified [(3)H]DFP-PR3. While we could not demonstrate cell surface PR3 on nonmyeloid cells after incubation with serum-containing supernatants of HL-60 cell cultures, we could do so after an overnight coculture period with HL-60 cell suspensions under the usual serum-containing culture conditions. Overall, our data would suggest that in vivo, the surface PR3 found on nonmyeloid cells is not endogenous but results from adsorption of PR3 extruded in their microenvironment by neighboring myeloid cells coming in close contact with them.

Abstract
The present study explored the relationship between psychosocial measures and the degree of coronary stenosis in a sample of 59 women between the ages of 39 and 84. Coronary occlusion was correlated with elevated cholesterol and marginally correlated with age and was inversely associated with years of education. Based on hierarchical multiple regression, an interview-based measure of hostility was associated with coronary stenosis after controlling for traditional risk factors, and age moderated the hostility-stenosis relationship. Further, a second regression model suggested that trait anxiety was inversely correlated with degree of occlusion, perhaps because low-anxious women are referred for catheterization later in the course of the disease. Contrary to hypotheses, there was no evidence that repression of interview-based hostility or anxiety predicted coronary occlusion. Given the small sample size, results should be considered preliminary. Future studies should explore the degree to which anxiety and hostility are associated with coronary heart disease (CHD) in larger samples of women and the degree to which age moderates the hostility-occlusion association.
