Midodrine in patients with spinal cord injury and anejaculation: A double-blind randomized placebo-controlled pilot study.

OBJECTIVE: The objective of this study is to evaluate the efficacy of midodrine in the treatment of anejaculation in men with spinal cord injury (SCI). STUDY DESIGN: Prospective, double-blind, randomized, placebo-controlled pilot study. METHOD: Men with anejaculation associated with SCI (level of injury above T10) of more than 1 year in duration were approached. Those with no ejaculatory response to one penile vibratory stimulation (PVS) trial were assigned in a double-blind manner to one of the two following interventions once a week for a maximum of 3 weeks or until ejaculation occurred: oral administration of flexible midodrine (7.5-22.5 mg max) followed by PVS (group M), or oral administration of flexible sham-midodrine (placebo) followed by PVS (group P). Sociodemographic data, medical characteristics, and plasma desglymidodrine concentration were collected for all participants. OUTCOME MEASURE: Ejaculation success rate in each group. RESULTS: Among the 78 men approached, 23 participants (level of SCI: C4-T9) were randomized. Three participants abandoned the study and 20 completed the study; 10 were assigned to group M, 10 to group P. Ejaculation was reached for one participant of group M and for two participants of group P. Autonomic dysreflexia associated to PVS occurred in three patients. CONCLUSION: In this small sample study, treatment of anejaculation after SCI with midodrine and PVS did not result in a better rate of antegrade ejaculation in 10 men than in 10 men treated with a placebo and PVS.

Revision of the Late Jurassic teleosaurid genus Machimosaurus (Crocodylomorpha, Thalattosuchia).

Machimosaurus was a large-bodied genus of teleosaurid crocodylomorph, considered to have been durophagous/chelonivorous, and which frequented coastal marine/estuarine ecosystems during the Late Jurassic. Here, we revise the genus based on previously described specimens and revise the species within this genus. We conclude that there were three European Machimosaurus species and another taxon in Ethiopia. This conclusion is based on numerous lines of evidence: craniomandibular, dental and postcranial morphologies; differences in estimated total body length; geological age; geographical distribution; and hypothetical lifestyle. We re-diagnose the type species Machimosaurus hugii and limit referred specimens to only those from Upper Kimmeridgian-Lower Tithonian of Switzerland, Portugal and Spain. We also re-diagnose Machimosaurus mosae, demonstrate that it is an available name and restrict the species to the uppermost Kimmeridgian-lowermost Tithonian of northeastern France. We re-diagnose and validate the species Machimosaurus nowackianus from Harrar, Ethiopia. Finally, we establish a new species, Machimosaurus buffetauti, for the Lower Kimmeridgian specimens of France and Germany (and possibly England and Poland). We hypothesize that Machimosaurus may have been analogous to the Pliocene-Holocene genus Crocodylus in having one large-bodied taxon suited to traversing marine barriers and additional, geographically limited taxa across its range.

Tooth serration morphologies in the genus Machimosaurus (Crocodylomorpha, Thalattosuchia) from the Late Jurassic of Europe.

Machimosaurus was a large-bodied durophagous/chelonivorous genus of teleosaurid crocodylomorph that lived in shallow marine and brackish ecosystems during the Late Jurassic. Among teleosaurids, Machimosaurus and its sister taxon 'Steneosaurus' obtusidens are characterized by having foreshortened rostra, proportionally enlarged supratemporal fenestrae and blunt teeth with numerous apicobasal ridges and a shorter anastomosed ridged pattern in the apical region. A recent study on 'S.' obtusidens dentition found both true denticles and false serrations (enamel ridges which contact the carinae). Here, we comprehensively describe and figure the dentition of Machimosaurus, and find that Machimosaurus buffetauti and Machimosaurus hugii have four types of serration or serration-like structures, including both denticles and false denticles on the carinae. The denticles are irregularly shaped and are not always discrete units, whereas the false denticles caused by the interaction between the superficial enamel ridges and the carinae are restricted to the apical region. Peculiarly, the most 'denticle-like' structures are discrete, bulbous units on the apicobasal and apical anastomosed ridges of M. hugii. These 'pseudo-denticles' have never, to our knowledge, previously been reported among crocodylomorphs, and their precise function is unclear. They may have increased the surface area of the apical region and/or strengthened the enamel, both of which would have been advantageous for a durophagous taxon feeding on hard objects such as turtles.

Multipronged intervention strategy to control an outbreak of Clostridium difficile infection (CDI) and its impact on the rates of CDI from 2002 to 2007.

OBJECTIVE: At the end of 2002, a new, more virulent strain of Clostridium difficile, designated BI/NAP1, was the cause of a massive outbreak of infection in the province of Quebec. This particular strain was associated with a dramatic increase in morbidity and mortality among affected patients in 2003-2004. We tested and implemented a multipronged infection control approach to curtail the rate of C. difficile infection (CDI). DESIGN: Five-year observational study. SETTING: A 554-bed, acute care tertiary hospital, the largest single medical center in Quebec, Canada. METHODS: To curtail the magnitude of the outbreak, we implemented a global strategy consisting of rapid C. difficile testing for all hospitalized patients who had at least 1 occurrence of liquid stool, the rapid isolation of patients infected with C. difficile in a dedicated ward with a specially trained housekeeping team, a global hand hygiene program, and the hiring of infection control practitioners. Antibiotic consumption at the institutional level was also monitored during the 5-year surveillance period. Cases of hospital-acquired CDI per 1,000 admissions were continuously monitored on a monthly basis during the entire surveillance period. RESULTS: The highest recorded CDI rate was 42 cases per 1,000 admissions in January 2004. Once additional infection control resources were put in place, the rate decreased significantly during the period from April 2005 to March 2007. During the 2003-2004 period, there were 762 cases of CDI (mean annual rate, 37.28 cases per 1,000 admissions) recorded in our study, compared with 292 cases of CDI (14.48 cases per 1,000 admissions) during the 2006-2007 period (OR, 0.379 [95% CI, 0.331-0.435]; p< .001), a 61% reduction. In March 2007, the equivalent of 4 full-time equivalent infection control practitioners were in place, which gave a ratio of 0.96 infection control practitioners per 133 beds in use, compared with the ratio of 0.24 infection control practitioners per 133 beds in use in 2003, and the total number of hours dedicated to cleaning and housekeeping increased by 26.2%. The total amount of antibiotics used in the hospital did not vary significantly from 2002 to 2007, although there were changes in the classes antibiotic used. CONCLUSION: The implementation of a multipronged intervention strategy to control the outbreak of CDI significantly improved the overall situation at the hospital and underlined the importance of investing in stringent infection control practices.

Risk factors and prevention for spinal cord injury from diving in swimming pools and natural sites in Quebec, Canada: a 44-year study.

BACKGROUND: Diving is the most frequent cause of spinal cord injury (SCI) from recreation and sport in Canada. This study was done to identify risk factors for SCI from diving in the province of Quebec. METHODS: An interview survey was done for a target population of 203 subjects with a SCI from diving treated in the two specialized rehabilitation centers in Quebec during 1961-2004. Telephone interviews of consenting individuals were used to collect pertinent personal, equipment, and environmental factors for each incident. RESULTS: Response was 44% (89/203); 92% were male and 85% <35 years old. Only 37% were aware prior to injury of the risk of SCI from diving, and only 33% had received water safety training. Swimming pools were the site of 51% (n=45) and natural bodies of water for 49% (n=44). 87% (n=39) of pools were single-unit home pools and 57% (n=26) above-ground. Depth indicators were absent for 100% of above-ground and 74% of in-ground pools. For SCI in in-ground pools, 63% resulted from striking the up-slope between deep and shallow ends. For dives at natural sites, a dock or wharf was the most frequent location, 36% (n=16). In 52% of pools and 79% of natural sites, depth was <1.4m (4.6ft). Signs prohibiting diving were absent in 96% of above-ground and 89% of in-ground pools. Alcohol was reported in 47% of SCIs. INTERPRETATION: The target for prevention of diving SCI is male youths and young adults. Above-ground pools are too shallow and small for diving. Deep ends of many in-ground pools are excessively shallow and short since many SCIs resulted from striking the up-slope. Prevention of SCI from diving needs to focus on education of potential victims, pool vendors and manufacturers, and regulations for safety norms in private pools. Water safety should highlight diving as a high-risk activity, and emphasize that most home pools and natural sites are unsafe. Safer evidence-based pool designs and more effective warnings need to be implemented.

The effect of electronegativity and angiotensin-converting enzyme inhibition on the kinin-forming capacity of polyacrylonitrile dialysis membranes.

The combination of negatively-charged membranes and angiotensin I-converting enzyme inhibitors (ACEi) evokes hypersensitivity reactions (HSR) during hemodialysis and bradykinin (BK)-related peptides have been hypothesized as being responsible for these complications. In this study, we tested the effects of neutralizing the membrane electronegativity (zeta potential) of polyacrylonitrile AN69 membranes by coating a polyethyleneimine layer (AN69-ST membranes) over the generation of kinins induced by blood contact with synthetic membranes. We used minidialyzers with AN69 or AN69-ST membranes in an ex vivo model of plasma and we showed that plasma dialysis with AN69 membranes led to significant BK and des-Arg(9)-BK release, which was potentiated by ACEi. This kinin formation was dramatically decreased by AN69-ST membranes, even in the presence of an ACEi, and kinin recovery in the dialysates was also significantly lower with these membranes. High molecular weight kininogen and factor XII detection by immunoblotting of the protein layer coating both membranes corroborated the results: binding of these proteins and contact system activation on AN69-ST membranes were reduced. This ex vivo experimental model applied to the plasma, dialysate and dialysis membrane could be used for the characterization of the kinin-forming capacity of any biomaterial potentially used in vivo in combination with drugs which modulate the pharmacological activity of kinins.

Estimated prevalence of obstructive sleep apnea-hypopnea syndrome after cervical cord injury.

OBJECTIVES: To estimate the prevalence of obstructive sleep apnea-hypopnea syndrome (OSAHS) in patients with cervical cord injury and to identify predictive factors. DESIGN: Cross-sectional study. SETTING: Rehabilitation center. PARTICIPANTS: Forty-one adults with cervical cord injury of more than 6 months in duration. INTERVENTIONS: Medical history, physical exam, and full in home overnight polysomnography were undertaken. Data were collected on characteristics of spinal cord injury, current medication, sleeping habits, daytime sleepiness, body mass index (BMI), and neck circumference. MAIN OUTCOME MEASURE: Presence or absence of OSAHS as defined by the American Academy of Sleep Medicine criteria (1999). RESULTS: Twenty-two (53%) patients (95% confidence interval [CI], 38.4%-68.9%) had OSAHS. Daytime sleepiness (odds ratio [OR], 41.1; 95% CI, 2.3-739.7; P=.02), BMI of 30 kg/m2 or higher (OR=17.2; 95% CI, 1.4-206.4; P=.03), and 3 or more awakenings during sleep (OR=34; 95% CI, 1.6-744.8; P=.03) were the best predictive factors of OSAHS obtained by a forward stepwise multiple logistic regression. CONCLUSIONS: The estimated prevalence of OSAHS is high after cervical cord injury. OSAHS should be suspected, especially in patients with daytime sleepiness, obesity, and frequent awakenings during sleep.

Generation of kinins during preparation and storage of whole blood-derived platelet concentrates.

BACKGROUND: Leukoreduction of platelet (PLT) concentrates (PCs) may be associated with hypotension in recipients, and a role for bradykinin (BK)-related peptides has been proposed for this side effect. STUDY DESIGN AND METHODS: The concentration of BK and one of its vasoactive metabolites, des-arginine(9)-BK (des-Arg(9)-BK), was measured in a large number of PCs as a function of leukoreduction and storage duration with specific enzyme immunoassays and complementary techniques. RESULTS: On Day 0 of storage, kinins were detected in leukoreduced and unfiltered PCs at a concentration lower than 100 pg per mL. During storage, both kinin levels peaked on Day 5 of storage, with a concentration higher than 1 ng per mL in 22 percent of PCs whether filtered on Day 0 or not. Physicochemical and pharmacologic characterizations of immunoreactive kinins confirm their nature. In vitro activation of the contact system of the corresponding PLT-poor plasma showed that a high kinin concentration on Day 5 of the storage corresponded with a low kinin-forming capacity of plasma. On Day 7, BK was no longer elevated presumably due to its degradation and the depletion of kinin-forming capacity of the plasma in stored PCs. The activities of metallopeptidases that metabolize BK-related peptides in plasma from PCs were at levels similar to those recorded in the plasma of a normal reference population and were unaffected by storage. CONCLUSION: Storage of PCs contributes to the hydrolysis of high-molecular-weight kininogen and generation of pharmacologically relevant BK levels that might pose a hazard in susceptible patients.

Expression of metallopeptidases and kinin receptors in swine oropharyngeal tissues: effects of angiotensin I-converting enzyme inhibition and inflammation.

Angiotensin I-converting enzyme inhibitors (ACEi) cause both chronic and acute side effects, including rare but potentially life-threatening angioedema (AE). The main hypothesis to be tested in this study was that metallopeptidases and kinin receptors are present in oropharyngeal tissues and that their expression is modulated by ACEi and inflammation. Novel real-time polymerase chain reaction analysis was developed and allowed the relative quantification of tissue's gene expression for neprilysin, membrane-bound aminopeptidase P (mAPP), and both B1 and B2 kinin receptor subtypes in tongue, parotid gland, and laryngeal tissue (areas especially involved in the gravest clinical forms of AE) and in kidney in a porcine model (single injection or 7-day ACEi oral treatments applied or lipopolysaccharide injected as a positive inflammatory control). The results provide evidence of the expression and activities of kininases in oropharyngeal tissues in the swine. ACEi treatment modulated the expression of neutral endopeptidase and mAPP mRNA, but the corresponding enzyme activities and that of angiotensin I-converting enzyme (ACE) were generally stable in tissues. The 7-day ACEi treatment up-regulated both kinin receptor mRNAs in the oropharynx and the B1 receptor mRNA in the lingual vascular endothelium (immunohistochemistry). The inhibition of ACE in plasma is responsible for an accumulation of bradykinin and des-arginine9-bradykinin generated during activation of the contact system with glass beads. The expression of critical components of the kallikrein-kinin system in the oropharyngeal tissues supports the role of kinins in ACEi-induced AE.

Human recombinant membrane-bound aminopeptidase P: production of a soluble form and characterization using novel, internally quenched fluorescent substrates.

APP (aminopeptidase P) has the unique ability to cleave the N-terminal amino acid residue from peptides exhibiting a proline at P(1)'. Despite its putative involvement in the processing of bioactive peptides, among them the kinins, little is known about the physiological roles of both human forms of APP. The purpose of the present study is first to engineer and characterize a secreted form of hmAPP (human membrane-bound APP). Our biochemical analysis has shown that the expressed glycosylated protein is fully functional, and exhibits enzymic parameters similar to those described previously for mAPP purified from porcine or bovine lungs or expressed from a porcine clone. This soluble form of hmAPP cross-reacts with a polyclonal antiserum raised against a 469-amino-acid hmAPP fragment produced in Escherichia coli. Secondly, we synthesized three internally quenched fluorescent peptide substrates that exhibit a similar affinity for the enzyme than its natural substrates, the kinins, and a higher affinity compared with the tripeptide Arg-Pro-Pro used until now for the quantification of APP in biological samples. These new substrates represent a helpful analytical tool for rapid and reliable screening of patients susceptible to adverse reactions associated with angiotensin-converting enzyme inhibitors or novel vasopeptidase (mixed angiotensin-converting enzyme/neprilysin) inhibitors.

Back strength cannot be predicted accurately from anthropometric measures in subjects with and without chronic low back pain.

OBJECTIVES: (1) To develop a multiple regression equation using anthropometric measurements to predict back strength and (2) to estimate the effect of practice on the back strength results and back strength predictions. DESIGN: Comparative study with repeated measures performed on three days. BACKGROUND: The assessment of back muscle relative endurance (% maximal strength) requires the measurement of maximal back strength which is problematic with low back pain patients. METHODS: The back strength (L5/S1 static extension moment), age and 26 anthropometric parameters were obtained from 83 male volunteers [42 healthy subjects and 41 chronic low back pain patients] aged between 20 and 60 years. A subsample of 20 healthy subjects and 20 patients were assessed through three days of testing to evaluate the variations of back strength with practice. RESULTS: The final regression model (n=42 healthy subjects) explained 39% of the variance in back strength. Back strength increased with practice (Day1

Hypotensive reaction during staphylococcal protein A column therapy in a patient with anomalous degradation of bradykinin and Des-Arg9-bradykinin after contact activation.

BACKGROUND: Hypotensive reactions have occurred in patients taking angiotensin converting enzyme (ACE) inhibitors after infusion of blood previously in contact with negatively charged surfaces capable of generating kinins, which accumulate when ACE, a kininase, is inhibited. A patient with anomalous bradykinin (BK) metabolism who experienced hypotension during extracorporeal staphylococcal protein A (SPA) therapy while on an ACE inhibitor was studied. CASE REPORT: A patient with mitomycin-associated hemolytic-uremic syndrome received SPA treatments after her ACE inhibitor, lisinopril, was held. Lisinopril was restarted before her 18th SPA treatment, and immediately after return of treated plasma she developed facial redness and hypotension, which resolved after the return stopped and recurred when restarted. To study formation and degradation of kinins, exposed her plasma to glass beads. We found a normal kinin formation rate but an abnormal degradation and accumulation of Des-Arg9-BK. The kinin degradation enzymes ACE, aminopeptidase P (APP), and carboxypeptidase N (CPN) were measured while on an ACE inhibitor, showing absence of ACE activity, low APP, but normal CPN. CONCLUSION: This patient's vasodilation and hypotension during SPA therapy was associated with a pre- existing anomaly of BK metabolism. Her ACE inhibitor shifted degradation toward Des-Arg9-BK formation, and her low APP was associated with a prolonged t50 and accumulation of the vasoactive Des-Arg9-BK.

Effect of force-feedback treatments in patients with chronic motor deficits after a stroke.

OBJECTIVE: To assess the effects a motor reeducation approach based on static dynamometers used to provide feedback on the force produced. DESIGN: The study design was a single-blind, randomized, controlled trial. Chronic stroke subjects participated in a 6-wk, thrice-weekly, force-feedback program of either the upper paretic limb (n = 13) or the lower paretic limb (n = 12). Baseline and postintervention assessments of the performance of both the upper and the lower limb were measured for each subject, the untreated paretic limb of each group serving as a control for the other group. RESULTS: With the exception of the handgrip force, strength measurements of the treated limb increased after completion of the treatment. The outcome measurements of the upper limb of the subjects included in the upper paretic limb were not significantly different after treatment from those measured in the lower paretic limb. In contrast, gait velocity and the distance walked in 2 min increased after treatment in the lower paretic limb as compared with the upper paretic limb, whereas the scores in the Fugl-Meyer test for the lower limb and the timed up-and-go test did not increase for either group after treatment. CONCLUSION: The results indicate that treatment of the lower limb based on force feedback produces an improvement of gait velocity.

Angiotensin-converting enzyme inhibitor-associated angioedema is characterized by a slower degradation of des-arginine(9)-bradykinin.

Angioedema (AE) is a rare but potentially life-threatening side effect of therapy with inhibitors of angiotensin-converting enzyme (ACE), the main bradykinin (BK)- inactivating metallopeptidase in humans. The pathogenesis of ACE inhibitor (ACEi)- associated AE (AE+) is presently unknown, although there is increasing evidence of a kinin role. We analyzed the metabolism of endogenous BK (B(2) receptor agonist) and its active metabolite, des-Arg(9)-BK (B(1) receptor agonist), in the presence of an ACEi during in vitro contact activation of plasma from hypertensive patients (n = 39) who presented AE+. Kinetic parameters were compared with those measured in a control group (AE-) of hypertensive patients (n = 39) who never manifested any acute or chronic side effects while treated with an ACEi. The different kinetic parameters were analyzed using a mathematical model (y = k t(alpha) e(-beta t)) previously applied to a normal, healthy population. The slope of BK degradation, but not its formation from high-molecular-weight kininogen, was lower in AE+ patients when compared with the AE- controls. des-Arg(9)-BK accumulation during the kinetic measurements was significantly higher in AE+ plasma. This accumulation of the B(1) agonist in AE+ patients paralleled its half-life of degradation. In conclusion, our results show, for the first time, that an abnormality of endogenous des-Arg(9)-BK degradation exists in the plasma of patients with ACEi-associated AE, suggesting that its pathogenetic mechanism lies in the catabolic site of kinin metabolism.

Colonic transit time after spinal cord injury: any clinical significance?

BACKGROUND: Both bowel dysfunction and increases in colonic transit time (CTT) are frequently observed in individuals with spinal cord injury; however, it is unknown whether there is an association between chronic intestinal problems and changes in CTTs. The current study investigates a possible relationship between the main intestinal symptoms of SCI patients and CTT values. METHODS: The following clinical variables and symptoms were investigated and collected in 30 individuals with SCI: total time for bowel care, abdominal pain, abdominal gas, success of rectal emptying, fecal incontinence, and decrease in quality of life. Total and segmental CTTs (right colon, left colon, and rectosigmoid colon) were assessed using radiopaque markers. The effects of the sociodemographic variables and the clinical symptoms on the different CTTs (total and segmental) were analyzed. RESULTS: The assessed clinical conditions were observed in the following percentages of subjects: abdominal gas symptoms (70%), fecal incontinence (56%), abdominal pain (63%), total time for bowel care > 1 hour (11%), difficult rectal emptying (66%), and decrease in quality of life (36%). We also observed an increase in total CTT in 47% of subjects; increases in segmental CTT were found in the right colon in 23%, in the left colon (60%), and in the rectosigmoid segment (23%). Statistical analyses failed to show a significant difference in mean CTT values between the group of symptomatic patients (1 or more symptoms) and the group of asymptomatic patients. No significant difference could be detected in the incidence of each intestinal symptom between the group of participants with normal CTT values and those with abnormal CTT values. For each of the clinical data assessed separately, a significantly longer CTT (left colon) was associated with the lack of abdominal pain (P < .03) and the presence of fecal incontinence (P < .01); successful rectal emptying was associated with significantly shorter total (P < .02) and segmental CTTs for the left colon (P < .01) and rectosigmoid colon (P < .05). CONCLUSIONS: Besides an association between shorter CTT and successful rectal emptying, there was little relationship between CTTs and intestinal symptoms in this study of patients with SCI.

Health behaviors of nursing students: a longitudinal study.

To ascertain the degree to which a health science curriculum may influence health-related behaviors among students, nine selected health behaviors of 52 undergraduate nursing students were studied for 3 consecutive years and compared to those of a similar group of education students. In addition, the health behaviors of both student groups were compared to those of the general population. During the study, the nursing students had no significant alterations in the observed health behaviors, and no significant differences were observed between the health behaviors of the two groups of students. Both groups manifested certain health behaviors that were significantly different from the general population. However, nursing students were observed more frequently to be significantly different from the general population. A 3-year nursing curriculum may have facilitated the adoption of some personal health behaviors, but the time demands of academic life may have induced students to reduce time-consuming health behaviors, such as getting enough sleep, eating breakfast, and exercising.

Aminopeptidase P in individuals with a history of angio-oedema on ACE inhibitors.

Angio-oedema is a rare but potentially life threatening side-effect of angiotensin-converting-enzyme (ACE) inhibitor treatment. Identification of individuals at risk of this adverse effect is not possible. Angio-oedema is associated with raised concentrations of bradykinin, which is mainly inactivated by ACE. We assessed the plasma activity of two other enzymes that catabolise bradykinin (aminopeptidase P and carboxypeptidase N) in 39 hypertensive patients with a history of angio-oedema during ACE inhibitor treatment and in 39 hypertensive patients who had never had ACE inhibitor associated side-effects. Patients with previous angio-oedema had a lower plasma activity of aminopeptidase P than did those who never presented with angio-oedema (p=0 003). Our data suggest that low plasma concentrations of aminopeptidase P could be a predisposing factor for development of angio-oedema in patients treated with ACE inhibitors.

Health-related quality of life after spinal cord injury.

PURPOSE: The purpose of this study was to assess health-related quality of life (HRQOL) in spinal-cord-injured adults living in Quebec (Canada). METHOD: Subjects with spinal cord injury (SCI) all of whom were members of the Quebec Paraplegic Association who gave their consent to participate completed the 36-item Short Form Health Survey (SF-36); sociodemographic and medical data were also solicited. RESULTS: Five hundred and eighty-seven participants were studied. The findings show a significant decrease in the score of the eight health concepts as measured by the SF-36 as well as that of the physical component summary measure (p<0.05). Analysing the various medical and sociodemographic variables with the eight scales of the SF-36 indicate that younger age, employment and the lack of hospitalization in the previous year were associated with a better quality of life. Mid- and long-term medical complications related to a spinal cord lesion and the impact of ageing are discussed briefly. CONCLUSION: HRQOL is decreased in the studied population with an SCI.
