- Abstract
Study design:Experts opinions consensus.Objective:To develop a common strategy to document remaining autonomic neurologic function following spinal cord injury (SCI).Background and Rationale:The impact of a specific SCI on a person's neurologic function is generally described through use of the International Standards for the Neurological Classification of SCI. These standards document the remaining motor and sensory function that a person may have; however, they do not provide information about the status of a person's autonomic function.Methods:Based on this deficiency, the American Spinal Injury Association (ASIA) and the International Spinal Cord Society (ISCoS) commissioned a group of international experts to develop a common strategy to document the remaining autonomic neurologic function.Results:Four subgroups were commissioned: bladder, bowel, sexual function and general autonomic function. On-line communication was followed by numerous face to face meetings. The information was then presented in a summary format at a course on Measurement in Spinal Cord Injury, held on June 24, 2006. Subsequent to this it was revised online by the committee members, posted on the websites of both ASIA and ISCoS for comment and re-revised through webcasts. Topics include an overview of autonomic anatomy, classification of cardiovascular, respiratory, sudomotor and thermoregulatory function, bladder, bowel and sexual function.Conclusion:This document describes a new system to document the impact of SCI on autonomic function. Based upon current knowledge of the neuroanatomy of autonomic function this paper provides a framework with which to communicate the effects of specific spinal cord injuries on cardiovascular, broncho-pulmonary, sudomotor, bladder, bowel and sexual function.

- Abstract
Background: Hospital medication errors are frequent and may result in adverse events. Data on non-prescription of regular medications to emergency department short stay unit patients is lacking. In response to local reports of regular medication omissions, a multi-disciplinary team was tasked to introduce corrective emergency department (ED) process changes, but with no additional financing or resources. Aim: To reduce the rate of non-prescription of regular medications for patients admitted to the ED Short Stay Unit (SSU), through process change within existing resource constraints. Methods: A pre- and post-intervention observational study compared regular medication omission rates for patients admitted to the ED SSU. Included patients were those who usually took regular home medications at 08:00 or 20:00. Omissions were classified as clinically significant medications (CSMs) or non-clinically significant medications (non-CSMs). The intervention included reinforcement that the initially treating acute ED doctor was responsible for prescription completion, formal checking of prescription presence at SSU handover rounds, double-checking of prescription completeness by the overnight SSU lead nurse and junior doctor, and ED pharmacist medication reconciliation for those still identified as having regular medication non-prescription at 07:30. Results: For the 110 and 106 patients in the pre- and post-intervention periods, there was a non-significant reduction in the CSM omission rate of -11% (95% CI: -23 to 2), from 41% (95% CI: 32-50) to 30% (95% CI: 21-39). Conclusion: Non-prescription of regular CSMs for SSU patients was not significantly reduced by institution of work practice changes within existing resource constraints., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

- Abstract
Introduction: Black people are disproportionately burdened by tobacco-related diseases and are less successful at cigarette cessation with current treatments. We know little about the effectiveness of e-cigarettes as a smoking cessation method compared to currently approved methods in Black adults who smoke. Many Black adults report experiencing racial discrimination in health care, but if discrimination is related to utilization of smoking cessation aids including e-cigarettes and success with smoking cessation in this population is unclear. Therefore, this exploratory study aimed to understand how negative experiences and racial discrimination in health care influence use of e-cigarettes for cigarette cessation and success with cigarette cessation among Black adults., Methods: The study interviewed 201 Black adults who used cigarettes and tried to quit in their lifetime from the Family and Community Health Study in 2016. The study asked if they had tried and successfully quit cigarettes with e-cigarettes vs. other methods (support groups, medications, nicotine replacement therapies, call-in help lines, cold turkey [quit on their own], counseling) and asked about their negative experiences and racial discrimination in health care. We performed separate logistic regressions that evaluated the association of negative experiences and racial discrimination in health care with 1) use of e-cigarettes for cigarette cessation vs. other quitting methods and 2) success with cigarette cessation using any method among Black adults while controlling for age, sex, socioeconomic status, health insurance status, and age of onset of cigarette use., Results: More reported negative experiences and racial discrimination in health care were associated with ever trying to quit with e-cigarettes compared to other methods (OR:1.75, 95 % CI [1.05-2.91]), but negative experiences and racial discrimination in health care were not associated with cigarette quitting success. Interestingly, trying e-cigarettes was associated with being less successful at quitting compared to using other methods to quit smoking (OR: 0.40, 95 % CI [0.20, 0.81])., Conclusions: These results suggest that educating health care professionals that anticipated discrimination in health care settings may be driving Black adults who smoke to engage in non-evidence-based smoking cessation practices, such as e-cigarettes instead of those that are evidence-based, and may be more effective in this population., Competing Interests: Declaration of competing interest The authors have no disclosures to report., (Copyright © 2023 Elsevier Inc.

- Abstract
Purpose: To determine the prevalence of fast global and central visual field (VF) progression in individuals with glaucoma under routine care., Design: Observational study., Participants: Six hundred ninety-three eyes of 461 individuals with glaucoma followed up over a median of 4.5 years., Methods: This study included (1) patients at a private ophthalmology clinic in Melbourne, Australia, and (2) individuals in 2 prospective longitudinal observational studies across 3 sites in the United States. All individuals had a diagnosis of glaucoma and were under routine care, and had performed 5 or more reliable 24-2 VF tests over a 1- to 5-year period. Ordinary least squares regression analyses were used to calculate the rate of global mean deviation (MD) change over time and the rate of the mean total deviation values of the 12 test locations within the central 10° region (MTD
10 ) for each eye., Main Outcome Measures: Prevalence of progression based on the rate of MD and the MTD10 change across various fixed cutoffs and cutoffs based on the estimated normal distribution (from the positive slopes)., Results: Based on the MD and the MTD10 , 12.5% and 11.7% of the eyes, respectively, exhibited a rate of change that was less than -1.0 dB/year (being a rate that typically is defined as "fast progression" for MD values), and 29.0% of the eyes showed a change of less than -0.5 dB/year on MTD10 . Furthermore, 12.7% and 9.1% of the eyes exhibited a rate of change that exceeded the 1% cutoff of the estimated normal distribution MD and the MTD10 values, respectively., Conclusions: This study found that approximately 1 in 8 eyes with glaucoma receiving routine care showed fast progression based on global MD values (< -1.0 dB/year) and that nearly 1 in 3 eyes showed a < -0.5 dB/year decline centrally. These findings highlight the clinical importance of assessing progressive central VF loss and reinforce the need for new therapies to prevent functional disability in a notable proportion of individuals who continue to exhibit fast progression., Financial Disclosure(s): Proprietary or commercial disclosure may be found after the references., (Copyright © 2023 American Academy of Ophthalmology.

- Abstract
Objective: To fully address physician burnout, academic medical centers need cultures that promote well-being. One observed driver of a culture of wellness is perceived appreciation. The authors identified several contributors to perceived appreciation among faculty at a large, metropolitan academic institution through use of a novel survey., Methods: The authors surveyed clinical faculty in five departments: psychiatry, emergency medicine, internal medicine, thoracic surgery, and radiology. Two open-ended response questions assessed sources of perceived and lack of perceived appreciation in narrative form. The authors also collected data on gender and department identity. Grounded theory methodology was used to analyze the narrative responses and design thinking to brainstorm specific recommendations based on the main themes identified., Results: A total of 179 faculty respondents filled out the survey for an overall response rate of 29%. Major drivers of perceived appreciation were patient and families (42%); physician, trainee and non-physician colleagues (32.7%); chairs (10%); and compensation (3.3%). Major drivers of perceived lack of appreciation were disrespect for time and skill level, including inadequate staffing (30%); devaluation by a physician colleague, chief of one's service or the chair (29%); poor communication and transparency (13%); and patient and family anger (6%)., Conclusions: Opportunities to improve perceived appreciation include structured communication of patient gratitude, community building programs, top of licensure initiatives and accountability for physician wellness, and inclusivity efforts from organizational leaders., (© 2021.

- Abstract
Background: Existing epidemiological data suggest differences across racial/ethnic groups in drug and alcohol treatment utilization and barriers to treatment and typically include only Black, Latine, and White adults. The objective of this study was to examine whether disparities remain for DSM-5 lifetime alcohol use disorder (AUD) and drug use disorder (DUD) treatment utilization and barriers across Black, American Indian/Alaska Native (AI/AN), Latine, Asian/Pacific Islander/Native Hawaiian (Asian/PI/NH), and White adults., Methods: The current study conducted secondary analyses on data from the National Epidemiological Survey on Alcohol and Related Conditions (NESARC-III). Regression analyses, followed by pairwise comparisons, investigated differences across racial/ethnic groups., Results: Analyses indicated differences across racial/ethnic groups in AUD treatment utilization. White and AI/AN adults were more likely to utilize a health care professional than were Black adults. Asian/PI/NH and Latine adults were more likely to endorse language as a barrier to AUD treatment than were White adults. Black adults were more likely to use 12-step programs for DUD treatment utilization than were White and Latine adults, and Black and White adults were more likely to use outpatient programs than were Latine adults. Further, Black adults were more likely than Asian/PI/NH and Latine adults to use specialty DUD treatment. AI/AN, Asian/PI/NH, and White adults were more likely to endorse fear of what others would think as a barrier to DUD treatment relative to Black adults. AI/AN adults were more likely to endorse fear of being hospitalized relative to Black, Latine, and White adults. Asian/PI/NH and Latine adults were more likely to indicate that the hours were inconvenient relative to Black and White adults. White adults were more likely to endorse a family member objected relative to Black adults. AI/AN and White adults were more likely to endorse they stopped on their own relative to Black, Asian/PI/NH, and Latine adults. Further, AI/AN and White adults reported the greatest number of barriers to DUD treatment., Conclusions: Differences remain across racial/ethnic group in drug and alcohol treatment utilization and barriers to treatment. Future research aimed at increasing treatment utilization across racial/ethnic groups should focus on social determinants of health., (Copyright © 2021 Elsevier Inc. All rights reserved.)

- Abstract
Background and Purpose: Paclitaxel, a widely used anti-cancer drug, is frequently associated with prolonged and severe peripheral neuropathies (PIPN), associated with neuroinflammation. Currently, PIPN effective treatments are lacking. Peroxisome Proliferator-Activated Receptor-α (PPAR-⍺) can modulate inflammatory responses. Thus, the use of PPAR-⍺ agonists, such as fibrates (fenofibrate and choline-fenofibrate), currently used in dyslipidemia treatment, could represent an interesting therapeutic approach in PIPN., Experimental Approach: Our studies tested the efficacy of fenofibrate (150 mg/kg, daily, i.p.) and choline fenofibrate (60 mg/kg daily, p.o.) in reversing and preventing the development of PIPN (paclitaxel: 8 mg/kg, i.p., every other day for 4 days) in male and female C57BL/6J mice. Mechanical and cold hypersensitivity, conditioned place preference, sensory nerve action potential (SNAP), as well as the expression of PPAR-⍺, TNF-⍺, IL-1β and IL-6 mRNA were evaluated., Key Results: While fenofibrate treatment partially reversed and prevented the development of mechanical hypersensitivity, this was completely reversed and prevented by choline-fenofibrate. Both fibrates were able to completely reverse and prevent cold hypersensitivity induced by paclitaxel. The reduction of SNAP amplitude induced by paclitaxel was also reversed by both fenofibrate and choline-fenofibrate. Our results indicate that suppression of paclitaxel-induced hypersensitivity by fibrates involves the regulation of PPAR-⍺ expression and decrease neuroinflammation in DRG. Finally, the co-treatment of Paclitaxel and fenofibric acid (fibrates active metabolite) was tested on different cancer cell lines, no decrease in the antitumoral effect of paclitaxel was observed., Conclusions and Implications: Taken together, our results show for the first time the therapeutic potential (prevention and reversal) of fibrates in PIPN and opens to a potential pharmacological repurposing of these drugs., (Copyright © 2021 Elsevier Inc.

- Abstract
Herbicides increase crop yields by allowing weed control and harvest management. Glyphosate is the most widely-used herbicide active ingredient, with $11 billion spent annually on glyphosate-containing products applied to >350 million hectares worldwide, using about 8.6 billion kg of glyphosate. The herbicidal effectiveness of glyphosate can depend upon the time of day of spraying. Here, we show that the plant circadian clock regulates the effectiveness of glyphosate. We identify a daily and circadian rhythm in the inhibition of plant development by glyphosate, due to interaction between glyphosate activity, the circadian oscillator and potentially auxin signalling. We identify that the circadian clock controls the timing and extent of glyphosate-induced plant cell death. Furthermore, the clock controls a rhythm in the minimum effective dose of glyphosate. We propose the concept of agricultural chronotherapy, similar in principle to chronotherapy in medical practice. Our findings provide a platform to refine agrochemical use and development, conferring future economic and environmental benefits.

- Abstract
Nicotinic acetylcholine receptors (nAChRs) are the primary target for nicotine, the addictive component in tobacco products. These pentameric receptors are made up of various subunits which contribute to the diverse functions of nAChR subtypes. The β3 subunit of the nAChR has been understudied in nicotine dependence, even though it is expressed in brain regions important for drug reward. Therefore, we assessed nicotine dependence behaviors in β3 wildtype (WT) and knockout (KO) male and female mice. We evaluated nicotine reward in the conditioned place preference (CPP) test and then measured nicotine withdrawal signs after chronic exposure to the drug. For the withdrawal studies, mice were continuously infused with 24 mg/kg/day of nicotine using surgically implanted osmotic mini-pumps for 14 days. Mini-pumps were removed at day 15, and withdrawal signs (somatic signs, hyperalgesia, anhedonia-like measure using the sucrose preference test and anxiety-like behaviors using the light dark boxes) were collected at 24 h intervals for three days following spontaneous withdrawal of nicotine. Nicotine-induced CPP did not differ between β3 KO and WT mice. β3 KO mice displayed similar somatic symptoms and hyperalgesia compared to WT mice but showed significant absence in affective (anhedonia and anxiety-like behaviors) withdrawal signs in nicotine-dependent mice. These observations suggest that the β3 nicotinic subunits do not seem to influence nicotine reward but plays an important role in affective nicotine withdrawal signs. Given the health burden of tobacco use disorder and the modest effect of smoking cessation aids, it is important to understand underlying factor contributing to nicotine dependence. The results of this study will further our knowledge of the role of the β3 nAChR subunit in nicotine reward and withdrawal behaviors in hopes of finding new molecular targets for smoking cessation aids., (Copyright © 2019 Elsevier Inc.

17. Bis-tropolonate complexes of tungsten: scaffolds for selective side-on binding of nitriles, imines and ketones.

Becica J, Jackson AB, Dougherty WG, Kassel WS, and West NM
- Abstract
The chiral bis-tropolonate tungsten(ii) tricarbonyl compound, (trop)2W(CO)3 (1), has been synthesized and structurally characterized. This seven-coordinate compound readily loses two carbonyl ligands to preferentially bind a series of π-bonding substrates to form six-coordinate complexes of the type (trop)2W(CO)(L). Alkynes coordinate strongly to form (trop)2W(CO)(η(2)-RCCR) (2) in which spectroscopic data is consistent with the alkyne serving as a 4-electron donor. Compound 1 will also preferentially coordinate organic nitriles in a side-on fashion through the CN triple bond. A dramatic shift in the nitrile carbon signals to greater than 210 ppm in the (13)C NMR confirms the nitriles are coordinated in an η(2) 4-electron donating capacity. Aldehydes, ketones, and imines also react with 1 to form 4-electron donor η(2) adducts. The imine adduct (trop)2W(CO)(η(2)-MeN=C(H)(tol)) (5) was characterized crystallographically and the short 1.91 A W-N bond distance supports the postulation of 4-electron donation from the imine through C=N π-bonding and N lone pair donation. Side-on coordination of ligands of this type is rare and may provide a means towards asymmetric functionalization of these substrates. All of the tropolonate compounds are prone to oxidation in air and the alkyne compounds will oxidize to stable W(IV) oxo alkyne species, (trop)2W(O)(η(2)-RCCR) (6). This causes a 90° rotation of the alkyne ligand and a reduction in alkyne donation to approximately 3 electrons, to maintain an optimal 18 electron configuration.

- Abstract
Objective: To assess the relationship between body mass index (BMI) and adiposity as well as the influence of injury level on this relationship in 24 women with spinal cord injury (SCI) and 23 able-bodied (AB) women with similar age, race, and BMI., Design and Methods: Body composition was measured by dual energy X-ray absorptiometry (DXA). Analysis of covariance was performed to compare total and regional soft tissue percent fat (PF) measures between groups., Results: Women with SCI had a higher soft tissue PF than AB women at any given BMI. The BMI-adjusted soft tissue PF (mean ± SE) was (44.4 ± 1.8)%, (37.8 ± 1.3)%, and (35.9 ± 1.1)% for tetraplegic, paraplegic, and AB women, respectively. The BMI explained about equal amounts of the variance in soft tissue PF among paraplegic and AB women (65%), but only 28% in tetraplegic women., Conclusion: This study confirms a limited use of BMI in measuring adiposity in women with SCI, particularly among those with tetraplegia. Our observation of lower BMI cutoff points for defining obesity (28 kg/m(2) for paraplegia and 21 kg/m(2) for tetraplegia) needs further confirmation. The underweight/malnutrition issue also deserves the consideration while proposing the ideal weight and BMI range for persons with SCI., (Copyright © 2013 The Obesity Society.)

- Abstract
Introduction: The present study describes the design and development of a new heterodimeric RGD-bombesin (BBN) agonist peptide ligand for dual receptor targeting of the form (64)Cu-NO2A-RGD-Glu-6-Ahx-BBN(7-14)NH(2) in which Cu-64=a positron emitting radiometal; NO2A=1,4,7-triazacyclononane-1,4-diacetic acid; Glu=glutamic acid; 6-Ahx=6-aminohexanoic acid; RGD=the amino acid sequence [Arg-Gly-Asp], a nonregulatory peptide that has been used extensively to target α(v)β(3) receptors up-regulated on tumor cells and neovasculature; and BBN(7-14)NH(2)=Gln-Trp-Ala-Val-Gly-His-Leu-Met-NH(2), an agonist analogue of bombesin peptide for specific targeting of the gastrin-releasing peptide receptor (GRPr)., Methods: RGD-Glu-6-Ahx-BBN(7-14)NH(2) was manually coupled with NOTA (1,4,7-triazacyclononane-1,4,7-triacetic acid), and the resulting conjugate was labeled with (64)Cu to yield (64)Cu-NO2A-RGD-Glu-6-Ahx-BBN(7-14)NH(2). Purification was achieved via reversed-phase high-performance liquid chromatography and characterization confirmed by electrospray ionization-mass spectrometry., Results: Competitive displacement binding assays displayed single-digit nanomolar IC(50) values showing very high binding affinities toward the GRPr for the new heterodimeric peptide analogues. In vivo biodistribution studies showed high uptake and retention of tumor-associated radioactivity in PC-3 tumor-bearing rodent models with little accumulation and retention in nontarget tissues. The radiolabeled conjugate also exhibited rapid urinary excretion and high tumor-to-background ratios. Micro-positron emission tomography (microPET) molecular imaging investigations produced high-quality, high-contrast images in PC-3 tumor-bearing mice 15 h postinjection., Conclusions: Based on microPET imaging experiments that show high-quality, high-contrast images with virtually no residual gastrointestinal radioactivity, this new heterodimeric RGD-BBN conjugate can be considered as a promising PET tracer candidate for the diagnosis of GRPr-positive tumors in human patients., (Published by Elsevier Inc.)

- Abstract
The authors look forward and discuss future directions in spinal cord injury (SCI) from a perspective of biomedical, psychosocial and technologic research. This discussion is based both on recent developments from various fields of knowledge and, more specifically, on SCI Model Systems' research contributions to medical rehabilitation. Biomedical research, as described here, includes (1) the process of moving from the "bench to bedside" and harnessing knowledge from basic science to produce new clinical treatment options for SCI during the life span; (2) the rapid proliferation of clinical trials aimed at neurologic recovery; (3) the growth of new technologies to restore and improve function; and (4) the challenges of developing relevant outcome measures to evaluate efficacy and effectiveness of interventions. Recent progress in psychosocial research has contributed significantly to understanding of the many factors associated with disability during the life course, the importance of quality of life issues, and the value of activity, participation, and the environment in promoting successful rehabilitation outcomes following SCI. Technology and bioengineering advances are discussed in relation to access to high-quality technology; restoration and replacement of movement; and technology to enhance rehabilitation outcomes., (Copyright © 2011 American Congress of Rehabilitation Medicine.

- Abstract
Cationic iminoacyl-carbonyl tungsten complexes of the type [W(CO) (eta (2)-MeNCR)(acac) 2] (+) (acac = acetylacetonate; R = Ph ( 1a), Me ( 1b)) easily undergo thermal substitution of CO with two-electron donors to yield [W(L)(eta (2)-MeNCR)(acac) 2] (+) (L = tert-butylisonitrile [R = Ph ( 2a), Me ( 2b)], 2,6-dimethylphenylisonitrile [R = Me ( 2c)], triphenylphosphine [R = Ph ( 3a), Me ( 3c)], and tricyclohexylphosphine [R = Ph ( 3b)]). Tricyclohexylphosphine complex 3b exhibits rapid, reversible phosphine ligand exchange at room temperature on the NMR time scale. Photolytic replacement of carbon monoxide with either phenylacetylene or 2-butyne occurs efficiently to form [W(eta (2)-alkyne)(eta (2)-MeNCR)(acac) 2] (+) complexes ( 5a- d) with a variable electron donor eta (2)-alkyne paired with the eta (2)-iminoacyl ligand in the W(II) coordination sphere. PMe 3 adds to 1a or 5b to form [W(L)(eta (2)-MeNC(PMe 3)Ph)(acac) 2] (+) [L = CO ( 4), MeCCMe ( 6)] via nucleophilic attack at the iminoacyl carbon. Addition of Na[HB(OMe) 3] to 5b yields W(eta (2)-MeCCMe)(eta (2)-MeNCHPh)(acac) 2, 8, which exhibits alkyne rotation on the NMR time scale. Addition of MeOTf to 8 places a second methyl group on the nitrogen atom to form an unusual cationic eta (2)-iminium complex [W(eta (2)-MeCCMe)(eta (2)-Me 2NCHPh)(acac) 2][OTf] ( 9[OTf], OTf = SO 3CF 3). X-ray structures of 2,6-dimethylphenylisonitrile complex 2c[BAr' 4 ], tricyclohexylphosphine complex 3b[BAr' 4 ], and phenylacetylene complex 5a[BAr' 4 ] confirm replacement of CO by these ligands in the [W(L)(eta (2)-MeNCR)(acac) 2] (+) products. X-ray structures of alkyne-imine complexes 6[BAr' 4 ] and 8 show products resulting from nucleophilic addition at the iminoacyl carbon, and the X-ray structure of 9[BAr' 4 ] reflects methylation at the imine nitrogen to form a rare eta (2)-iminium ligand.

- Abstract
Background: At the 2006 National Institute on Disability and Rehabilitation Research (NIDRR) sponsored pre-conference on spinal cord injury (SCI) outcomes, several gait and ambulation measures were evaluated for utility in clinical practice, validity, and reliability as research measurement tools. The Conference Subcommittee on Gait and Ambulation chose to review the Walking Index for Spinal Cord Injury II (WISCI II), 50-Foot Walk Test (50FTWT), 6-Minute Walk Test (6MWT), 10-Meter Walk Test (10MWT), and Functional Independence Measure-Locomotor (FIM-L)., Methods: A subcommittee of international experts evaluated each instrument for test construct, administration, population applicability, reliability, sensitivity to change, and validity. Evaluations for each outcome measure were compiled, distributed to the whole committee, and then further reviewed with addition of comments and recommendations for consensus. An audience of experts voted on the validity and usefulness of each measure., Results: WISCI II and 10MWT were found to be the most valid and clinically useful tests to measure improvement in gait for patients with SCI. FIM-L had little utility and validity for research in SCI. 6MWT and 50FTWT were found to be useful but in need of further validation or changes for the SCI population., Conclusion: A combination of the 10MWT and WISCI II would provide the most valid measure of improvement in gait and ambulation in as much as objective changes of speed, and functional capacity allow for interval measurement. To provide the most comprehensive battery, however, it will be important to include a measure of endurance such as the 6MWT. Further validation and study should be devoted to WISCI II, 10MWT, and 6MWT as primary outcome measures for gait in SCI.

- Abstract
Women with spina bifida have unique health care concerns and as the life expectancy of this population increases, they are transitioning from adolescence to womanhood and entering their reproductive years with little information about what to expect. Likewise, their health care providers do not have the benefit of evidence-based research that comprehensively addresses the issues these women may face related to reproduction or aging. Few studies have focused on the effects that spina bifida may have on these women's reproductive systems, nor has attention been paid to the effects that possible reproductive endocrine changes may have on their disability. Needless to say, concerns about sexuality, sexual function, and pregnancy are just as important to these women as they are to their able-bodied counterparts.

- Abstract
Study Design: Double-blind, randomized, placebo-controlled, parallel-group clinical trial., Objective: Assess safety and efficacy of sustained-release fampridine in subjects with chronic spinal cord injury., Setting: A total of 11 academic rehabilitation research centers in the United States., Methods: A total of 91 subjects with motor-incomplete spinal cord injury (SCI), randomized to three arms: fampridine, sustained release, 25 mg b.i.d. (Group I), 40 mg b.i.d. (Group II), and placebo (Group III) for 8 weeks., Outcome Measures: Patient diary questionnaire, Ashworth score, American Spinal Cord Injury Association International Standards, International Index of Erectile Function, bladder and bowel management questionnaires, and Clinician and Subject Global Impressions (Clinician Global Impression of change, Subject Global Impression (SGI)). Safety was evaluated from adverse events, physical examinations, vital signs, electrocardiograms, and laboratory tests., Results: In total, 78% of the subjects completed the study. More (13/30) discontinued from Group II than Group I (4/30) and Group III (3/31). The most frequent adverse events across groups were hypertonia, generalized spasm, insomnia, dizziness, asthenia, pain, constipation, and headache. One subject in Group II experienced a seizure. SGI changed significantly in favor of Group I (P=0.02). Subgroup analysis of subjects with baseline Ashworth scores >1 showed significant improvement in spasticity in Group I versus III (P=0.02)., Conclusions: Group I showed significant improvement in SGI, and potential benefit on spasticity. The drug was well tolerated. Group II showed more adverse events and discontinuations.

Jackson AB, White PS, and Templeton JL
- Abstract
Two equivalents of acetylacetonate (acac) have been successfully introduced into a monomeric tungsten(II) coordination sphere. With the tetracarbonyltriiodotungsten(II) anion as a precursor, the formation of a tungsten(II) bis(acac) tricarbonyl complex, W(CO)3(acac)2, 1, has been accomplished. The addition of PMe3 or PMe2Ph to tricarbonyl complex 1 formed tungsten(II)bis(acac)dicarbonylphosphine complexes 2a and 2b, respectively. Single-crystal X-ray diffraction studies of the parent tricarbonyl complex, 1, and dicarbonyl trimethylphosphine complex 2a confirmed seven-coordinate geometries for both complexes. Variable-temperature 1H and 13C{1H} NMR spectroscopy revealed fluxional behavior for these seven-coordinate molecules: rapid exchange of the three carbon monoxide ligands in 1 was observed, and movement of the phosphine ligand through a mirror plane in a C(S) intermediate species was observed for both 2a and 2b. Tricarbonyl complex 1 reacted readily with alkyne reagents to form bis(acac)monocarbonylmonoalkynetungsten(II) complexes 3a (PhC(triple bond)CH) and 3b (MeC(triple bond)CMe). Variable-temperature 1H NMR spectroscopy was used to probe rotation of the alkyne ligand in 3a and 3b. The introduction of two alkyne ligands was accomplished thermally using excess PhC(triple bond)CPh to form bis(alkyne) complex 4 which was characterized crystallographically, as well as by 1H and 13C NMR spectroscopy. The availability of W(CO)3(acac)2 as a source of the W(acac)2 d4 moiety lies at the heart of the chemistry reported here.

- Abstract
Study Design: A single group uncontrolled trial., Objectives: Despite widespread emphasis on the obesity-related health risks in persons with spinal cord injury (SCI), limited research has been carried out to intervene in this problem. This study was conducted to assess the initial effectiveness of a weight loss program on various health outcomes in persons with SCI., Setting: A rehabilitation center in Birmingham, Alabama, United States., Methods: A total of 16 individuals with chronic SCI who were overweight or obese participated in a weight management program that consisted of 12 weekly classes, covering nutrition, exercise, and behavior modification. Various outcomes were examined over a 6-month period (baseline, week 12, and week 24), including body composition measured by dual energy X-ray absorptiometry, physiologic measures, diet behavior, and psychosocial and physical functioning. Of these, 13 participants returned for the week 24 follow-up., Results: Weight loss averaged 3.5+/-3.1 kg (3.8% of the initial weight) at week 12 and 2.9+/-3.7 kg (3.0% of the initial weight) at week 24. There was a significant reduction from baseline values at weeks 12 and 24 in body mass index, anthropometric measurements, and fat mass and improvement in diet behavior and psychosocial and physical functioning, while lean mass and blood albumin and hemoglobin levels were maintained. A correlation analysis showed that a greater weight loss was importantly (r>0.4) associated with a greater reduction in total cholesterol at weeks 12 and 24 and in systolic and diastolic blood pressure at week 24. Several factors were important (r>0.4 or r<-0.4) in determining the success in weight loss, including age, race, marital and employment status, family history of overweight/obesity, level and duration of injury, and cholesterol level at baseline., Conclusions: This is the first demonstration that a carefully planned program with time-calorie displacement diet is effective for overweight/obese individuals with SCI to lose weight without compromising total lean mass and overall health. It provides foundation for a future large clinical trial for weight loss of persons with SCI or other spinal cord dysfunction.

- Abstract
Objective: To examine age-period-duration patterns of the prevalence of pressure ulcers in community-residing people with spinal cord injury (SCI)., Design: Multicenter cohort study., Setting: Nine Model Spinal Cord Injury Systems throughout the United States., Participants: People with SCI (N=3361) injured between 1986 and 1995 and followed up thereafter on a yearly basis through 2002., Interventions: Not applicable., Main Outcome Measure: Physician-confirmed pressure ulcers of stage II or greater at the follow-up visits., Results: The multivariable generalized estimating equations model showed a significant trend toward increasing pressure ulcer prevalence in the recent years (1994-2002 vs 1984-1993: odds ratio=1.4; 95% confidence interval, 1.2-1.6) not explained by aging, years since injury, or demographic and clinical factors. The risk of pressure ulcers appeared to be steady during the first 10 years and increased 15 years postinjury. Pressure ulcers were more common among the elderly, men, African Americans, singles, subjects with education less than high school, unemployed, subjects with complete injury, and subjects with history of pressure ulcers, rehospitalization, nursing home stay, and other medical conditions. Injury cause and level had no significant effect., Conclusions: These results highlight the need for research into factors that contribute to the increasing pressure ulcer prevalence.

- Abstract
Background/objectives: Few studies have adequately examined the unique issues of women with spina bifida as they enter their reproductive years. Most studies are anecdotal, retrospective case studies that contribute little to our understanding of the physiological effects of the disability on the reproductive system and, conversely, the effects of the reproductive endocrine changes on the woman's disability. The purpose of this article was to review previously published reports on the reproductive issues facing female adolescents and women and to ascertain the current knowledge so that future research needs can be established., Methods: Multiple MEDLINE searches were performed for publications from 1957 through the present pertaining to females/women with spina bifida and/or disabilities. Papers were then chosen if information was provided on menarche, menstruation and sexual maturation, gynecologic issues, sexual function, birth control, pregnancy outcomes, and menopause. These were then reviewed and classified according to the level of evidence (as defined by Ball et al)., Results: More than 150 titles and abstracts were reviewed for inclusion. Of these, 75 papers met the guidelines for the subject content. Studies were stratified by level of evidence and included 1 study at level 3, 71 studies at level 4, and 3 studies at level 5., Conclusion: Little research has examined the reproductive issues of women with spina bifida and women with other neurologic disabilities. Future controlled prospective research studies are needed to examine issues related to puberty and sexual and gynecologic issues throughout the life span and pregnancy in these populations.

- Abstract
Travel to remote destinations has increased dramatically in recent years. The Clinical Pharmacy International Travel Clinic (CPITC) was established in 1991 in the Kaiser Permanente Colorado Region to provide pre-travel advice to members to decrease their risk of travel-related diseases. The CPITC is unique from other travel medicine clinics because it is a pharmacist-run telepharmacy service. The team includes an infectious diseases physician, an infectious diseases clinical pharmacy specialist, 4 clinical pharmacists, and a pharmacy technician. The clinical pharmacists provide consultations via telephone. Both patient- and trip-related information are gathered to assess the traveler's health risks. Recommendations are provided regarding food- and water-borne diseases, insect-borne diseases, sexually transmitted diseases, and diseases related to animal bites. Additionally, detailed information is provided on vaccines that may be needed to protect travelers against various diseases. The travel consult is documented electronically. A copy of the consult, along with a booklet that provides travel information, is mailed to the patient. Success of the CPITC is demonstrated in several ways. The clinic initially served Kaiser Permanente members in the Colorado Region. The service has expanded and now also provides travel consults to Kaiser Permanente members in the Northwest and Ohio Regions. Patient satisfaction is high, and significant cost-savings have been realized secondary to avoiding the use of unnecessary vaccinations and medications. The CPITC allows resources to be leveraged and provides one center where individuals trained in travel medicine provide information to members, thus improving efficiency and decreasing cost.

- Abstract
Objective: To assess gender differences in neurologic and functional outcome measures in persons with spinal cord injury (SCI)., Design: Case series., Settings: Model Spinal Cord Injury Systems (MSCIS) throughout the United States., Participants: People (N=14,433) admitted to an MSCIS within 30 days of injury., Interventions: Not applicable., Main Outcome Measures: Improvement in American Spinal Injury Association (ASIA) motor index score, ASIA Impairment Scale, level of injury, and FIM instrument scores after SCI., Results: When examining subjects grouped by severity of injury, changes in ASIA motor index total scores, from system admission to 1-year anniversary, were significantly greater for women than men with either complete ( P =.035) or incomplete ( P =.031) injuries. Functional comparison of men and women, using the FIM motor subscale, revealed that men had higher FIM motor scores at rehabilitation discharge among those with motor-complete injuries, except for those with C1-4 and C6 neurologic levels. Women with motor-incomplete high tetraplegia (C1-4 levels) had higher discharge FIM motor scores than did similarly afflicted men. There were no significant differences in FIM motor scores among men and women with other levels of motor incomplete SCI., Conclusions: Gender differences in SCI were seen in several areas. Women may have more natural neurologic recovery than men; however, for a given level and degree of neurologic injury, men tend to do better functionally than women at time of discharge from rehabilitation. Future prospective study of the effects of estrogen on neurologic recovery and the effects of gender on functional potential are recommended.

- Abstract
Objective: To examine the association of health, community integration, and economic status with subsequent mortality and life expectancy among persons with spinal cord injury., Design: Cohort study., Setting: Model Spinal Cord Injury Systems (MSCIS) hospitals., Participants: A total of 5947 persons injured since 1973 who were enrolled in the National Spinal Cord Injury Database and who were still alive and received an annual evaluation from November 1995 through March 2002., Interventions: Not applicable., Main Outcome Measure: Mortality was determined by routine follow-up supplemented by information from the Social Security Death Index. A logistic regression model based on the full set of predictor variables was developed to estimate the chance of dying in any given year., Results: After adjusting for demographic characteristics and injury severity, health status indicators, measures of community integration, and economic status indicators all had relatively small but statistically significant effects (20%-70% increases) on the likelihood of dying during the next year. Inclusion of these factors may result in higher life expectancy estimates under highly favorable conditions., Conclusions: Whereas previous reports of the MSCIS data have identified the life expectancies associated with a particular set of demographic (eg, age, gender) and injury-related characteristics (level and completeness of injury; ventilator dependence), the current analysis suggests that consideration of health, economic, and psychosocial factors may make computations of life expectancy more accurate.

- Abstract
Objective: To evaluate epidemiologic trends in new spinal cord injuries (SCIs) in the United States over 3 decades., Design: Consecutive case series., Setting: Model Spinal Cord Injury Systems (MSCIS) facilities., Participants: Persons (N=30,532) admitted to MSCIS facilities within 365 days of injury between 1973 and 2003, and enrolled in the National Spinal Cord Injury Database., Interventions: Not applicable., Main Outcome Measures: Data were collected at MSCIS admission and rehabilitation discharge. Variables included age, gender, race and ethnic group, year of injury, and level and extent of injury. Specific etiologies were grouped as motor vehicle collisions (MVCs), violence, falls, sports, and other. Demographic and injury severity trends were analyzed by year of injury groupings according to decades (1973-1979, 1980-1989, 1990-1999, 2000-2003.) Chi-square tests assessed statistical significance. One-way analysis of variance compared mean ages., Results: The male/female ratio remained fairly stable at 4:1, but the percentage of women increased slightly over time, especially from MVC etiologies ( P <.001). Over time, the mean age at injury increased significantly ( P <.001); it was 37.7+/-17.5 years in 2000-2003. The majority of cases were white (66.1%). Tetraplegia (54.1%) and complete injuries (55.6%) occurred more than paraplegia and incomplete injuries, respectively. MVCs (45.6%) remained the most common etiology; falls (19.6%) held the second position over violence (17.8%), except for the 1990-1999 period when the positions were reversed. Significantly increasing percentages of new injuries were seen for SCI due to automobile, motorcycle, bicycle, and all-terrain vehicle crashes, blunt object attacks, snow skiing, and medical and surgical mishaps., Conclusions: Many previously seen SCI demographic trends continued into the 2000 decade.

- Abstract
This issue of the Archives of Physical Medicine and Rehabilitation is dedicated to current research findings of the Model Spinal Cord Injury Systems (MSCIS) program. The MSCIS grants were established by the Rehabilitation Services Administration in the 1970s. Now administered by the National Institute on Disability and Rehabilitation Research within the Office of Special Education and Rehabilitation Services in the US Department of Education, the program has included 27 spinal cord injury centers in the United States over the years. In the current 5-year grant cycle (2000-2005), there are 16 designated regional MSCIS centers. In addition to establishing a comprehensive system of care, the grantees contribute patient data to the National Spinal Cord Injury Database (which now contains data on 30,532 subjects with follow-up of up to 30 y). In addition, the MSCIS grants enable the conduct of site-specific and collaborative research projects. To highlight the research findings of the program, the MSCIS have produced a special dissemination effort during each of the previous 5 grant cycles, with this issue of the Archives representing the latest of these endeavors. This article provides a brief history of the MSCIS program and highlights the important findings of the 17 original research articles contained in this issue.

- Abstract
Objective: To determine the predictive value of serum levels of creatine phosphokinase (CPK) and alkaline phosphatase (ALP) in identifying patients with spinal cord injury (SCI) who are at risk to develop heterotopic ossification (HO) at the hips., Design: Prospective cohort study., Setting: Tertiary-care level I trauma center., Participants: Consecutive sample of 18 adults with acute traumatic SCI. Patients were excluded if they had medical or surgical conditions that are known to cause elevated enzyme levels., Interventions: Not applicable., Main Outcome Measures: Conventional hip radiographs were taken approximately 3 weeks after injury and again from between 3 to 6 months after injury. Serum ALP and CPK were measured approximately 3 weeks after SCI. Patients were later separated into 2 groups: group 1 was comprised of those who developed HO and group 2 was comprised of those who did not., Results: The initial radiographs showed no evidence of HO in either group. The radiographs taken at 3 to 6 months showed HO in 7 of 18 patients. The levels of CPK at the initial evaluation were significantly higher (R=.947, P<.0024) in group 1 than in group 2 and correlated with the severity of HO. There was no correlation between serum ALP levels and subsequent development of HO between the 2 groups (P=.07)., Conclusion: Elevated serum levels of CPK have value in predicting the HO.

- Abstract
Objective: An evaluation of the history, design, and status of the database of the National Spinal Cord Injury Statistical Center (NSCISC) was undertaken to identify its continued relevance., Research Design: A systematic review was conducted of goals, content, and quality control procedures, as well as its suitability and public availability for conducting future epidemiologic and health services research., Results: The NSCISC database contains information on approximately 29,000 persons injured since 1973 and treated at any regional model spinal cord injury system within 1 year of injury. The NSCISC database is structured longitudinally with data collected at discharge, 1 year after injury, 5 years after injury, and every 5 years thereafter. The database includes information on demographics, injury severity, medical complications, surgical procedures, types and amounts of therapy, length of stay, charges, and both short-term and long-term treatment outcomes. Strengths include large sample size, use of valid and reliable measures, geographic and patient diversity, comprehensiveness, availability of long-term prospective follow-up information, good case identification, and rigorous quality control procedures. Limitations include lack of population basis, inclusion of only model system patients, losses to follow-up, and other missing data. Recent content additions include detailed information on each treatment phase, depression, substance abuse, environmental barriers to community integration, and patient identifying information. A process exists for researchers to gain access to the data., Conclusions: The database remains a valuable resource. Future plans include linkage to other databases to enhance research capability, a published research compendium, and development of a user's guide to facilitate database usage.

- Abstract
As the treatment of SCI and its secondary medical complications improves, women with SCI are becoming increasingly successful in re-integrating themselves into society. Part of this re-integration involves the resumption of active sexual lives and motherhood. Clinicians who care for patients with SCIs play an important role in facilitating the resumption of these roles. With appropriate follow-up and care, women with SCI should be expected to maintain good gynecologic health and deliver healthy children with minimal complications.

- Abstract
Objective: To examine upper-extremity motor recovery of subjects with tetraplegia with both complete and incomplete injuries, to predict which patients and at what time they would recover a motor level., Design: Prospective, multicenter clinical study of upper-extremity motor recovery in subjects with acute traumatic spinal cord injury., Setting: Three regional spinal cord injury centers., Subjects: One hundred sixty-seven individuals with acute traumatic tetraplegia (144 males [86%], and 23 females [14%]) between the ages of 15 and 75 years (mean age, 35.5 yrs)., Methods: Subjects were examined and classified using sequential manual muscle tests performed on admission, 72 hours, 1, 2, and 3 weeks, and 1, 2, 3, 6, 12, 18, and 24 months postinjury. C5 biceps, C6 extensor carpi radialis, C7 triceps, and C8 flexor digitorum profundus were evaluated using a 0-5 scale. Analyses of the right motor levels used a series of logistic regression models, and for multiple measurements on each subject, models were estimated using generalized estimating equations., Results: The analysis for recovery of the biceps for the C4 group showed 70% of complete compared with 90% of incomplete injuries recovered (p < .001); of the extensor carpi radialis in the C5 group, 75% complete and 90% incomplete recovered (p < .002); and of the triceps in the C6 group, 85% of complete and 90% of incomplete injuries recovered (p < .16)., Conclusion: Predicting future potential for upper-extremity motor recovery and for independence in self-care in groups of patients at a specific motor level is possible within the first week of injury.

- Abstract
Objective: To analyze the incidence, risk factors, and trends of long-term secondary medical complications in individuals with traumatic spinal cord injury., Design: Data were reviewed from the National SCI Statistical Center on annual evaluations performed at 1, 2, 5, 10, 15, and 20 years after injury on patients injured between 1973 and 1998., Setting: Multicenter Regional SCI Model Systems., Main Outcome Measures: Secondary medical complications at annual follow-up years, including pneumonia/atelectasis, autonomic dysreflexia, deep venous thrombosis, pulmonary embolism, pressure ulcers, fractures, and renal calculi., Results: Pressure ulcers were the most frequent secondary medical complications in all years, and individuals at significant (p < .05) risk included those with complete injuries (years 1, 2, 5, 10), younger age (year 2), concomitant pneumonia/atelectasis (year 1, 2, 5), and violent injury (years 1, 2, 5, 10). The incidence of pneumonia/atelectasis was 3.4% between rehabilitation discharge and year-1 follow-up with those most significantly at risk being older than 60 years (years 1, 2, 5, 10) and tetraplegia-complete (years 1, 2). One-year incidence of deep venous thrombosis was 2.1% with a significant decline seen at year 2 (1.2%), and individuals most significantly (p < .001) at risk were those with complete injuries (year 1). The incidence of calculi (kidney and/or ureter) was 1.5% at 1-year follow-up and 1.9% at 5 years and was more frequent in patients with complete tetraplegia. Intermittent catheterization was the most common method of bladder management among patients with paraplegia but became less common at later postinjury visits., Conclusions: Pressure ulcers, autonomic dysreflexia, and pneumonia/atelectasis were the most common long-term secondary medical complications found at annual follow-ups. Risk factors included complete injury, tetraplegia, older age, concomitant illness, and violent injury.

- Abstract
Objective: Little attention has been given to women's reproductive health issues in the disabled population. This study documents the unique reproductive health conditions, complications, and behaviors in women with spinal cord injury (SCI)., Subjects: A total of 472 women at least 18 years of age who were at least 1 year post-SCI. Their average age at injury was 32 years., Design: An extensive questionnaire regarding gynecologic, sexual, obstetric, and menopausal health issues was developed and piloted. The questionnaire was then administered by a trained woman health care clinician to women who agreed to participate in the study., Setting: Private outpatient clinics at 10 regional model SCI systems of care., Results: Women reported similar gynecologic problems in both preinjury and postinjury time periods. Exceptions were urinary tract infections and vaginal yeast infections. Sexually transmitted infections appear to be less common after injury, but the difference was not statistically significant. The number of hysterectomies was similar both before and after injury, but reasons differed greatly. Women with SCI were less likely to have routine mammograms. They reported similar preventive practices such as performing self-breast examinations and obtaining Papanicolaou smears. Almost 14% of women with SCI became pregnant after injury (101 pregnancies). Complications from pregnancy, labor, and delivery were reported to be more frequent in their postinjury than in their preinjury obstetric experiences. They tended to have babies of lower birth weight and with more complications at time of delivery. Of the sample, 87% reported having sexual intercourse before injury, with only 67% having intercourse after injury. Years postinjury and level of injury were predictive of intercourse; extent of injury was not. Experience of orgasms and methods of contraception varied among the two groups. There were significant complaints of dysreflexia and bladder incontinence with sexual function. Menopause after injury was reported by 14.6% of the women. Postinjury menopausal symptoms were of low frequency, but more than those reported by women who had undergone menopause before injury. Only 19% of women who had menopause after SCI were placed on hormone replacement therapy. Almost one third of the women who had menopause after injury reported new bone fractures., Conclusion: This study illustrates the unique reproductive health concerns of women with SCI. Many pregnancy, labor, and delivery experiences in these women are different. Sexual activity and function have several disability-related consequences and the effects of menopause are still unknown, but may be more problematic than for able-bodied women.

- Abstract
The optimal management of acute spinal cord injuries remains to be defined. The authors prospectively applied resuscitation principles of volume expansion and blood pressure maintenance to 77 patients who presented with acute neurological deficits as a result of spinal cord injuries occurring from C-1 through T-12 in an effort to maintain spinal cord blood flow and prevent secondary injury. According to the Intensive Care Unit protocol, all patients were managed by using Swan-Ganz and arterial blood pressure catheters and were treated with immobilization and fracture reduction as indicated. Intravenous fluids, colloid, and vasopressors were administered as necessary to maintain mean arterial blood pressure above 85 mm Hg. Surgery was performed for decompression and stabilization, and fusion in selected cases. Sixty-four patients have been followed at least 12 months postinjury by means of detailed neurological assessments and functional ability evaluations. Sixty percent of patients with complete cervical spinal cord injuries improved at least one Frankel or American Spinal Injury Association (ASIA) grade at the last follow-up review. Thirty percent regained the ability to walk and 20% had return of bladder function 1 year postinjury. Thirty-three percent of the patients with complete thoracic spinal cord injuries improved at least one Frankel or ASIA grade. Approximately 10% of the patients regained the ability to walk and had return of bladder function. As of the 12-month follow-up review, 92% of patients demonstrated clinical improvement after sustaining incomplete cervical spinal cord injuries compared to their initial neurological status. Ninety-two percent regained the ability to walk and 88% regained bladder function. Eighty-eight percent of patients with incomplete thoracic spinal cord injuries demonstrated significant improvements in neurological function 1 year postinjury. Eighty-eight percent were able to walk and 63% had return of bladder function. The authors conclude that the enhanced neurological outcome that was observed in patients after spinal cord injury in this study was in addition to, and/or distinct from, any potential benefit provided by surgery. Early and aggressive medical management (volume resuscitation and blood pressure augmentation) of patients with acute spinal cord injuries optimizes the potential for neurological recovery after sustaining trauma.

- Abstract
From 1985 to 1990 five Model Regional Spinal Cord Injury (SCI) Care Systems participated in a collaborative effort to prospectively document the occurrence of adult respiratory distress syndrome (ARDS), aspiration, atelectasis, bronchitis, bronchospasm, lung abscess, pleural effusion, pneumonia, pneumo/hemothorax, pulmonary edema, pulmonary thromboembolism, tracheitis, upper respiratory infection, and ventilatory failure in patients admitted within 48 hours of SCI with a level of C1-T12 and Frankel Grade A, B, or C. The mean, standard deviation and range was calculated for the time of onset and duration of each complication. Of the 261 patients who entered the study, 175 (67%) experience 544 respiratory complications with atelectasis being the most common (36.4%) followed by pneumonia (31.4%) and ventilatory failure (22.6%). These complications occurred on the average of 17.7 days, 24.5 days and 4.5 days postinjury and lasted 12.8 days, 15.5 days, and 35.9 days, respectively. Twenty-two percent, 47%, and 31% had injury levels at C1-4, C5-8, T1-12, respectively with the majority being Frankel Grade A (78%). Eighty-four percent of C1-4, 60% of the C5-8, and 65% of the T1-12 had respiratory complications. Statistical analysis revealed complications to be significantly greater (p < .05) and of longer duration (p < .05) for the C1-4 group. Ventilatory failure and aspiration were the earliest to occur (at 4.5 days) for all SCI patients. Surprisingly, however, complications overall occurred significantly sooner (p < .05) in the T1-12 group. In conclusion, patients who sustain SCI have a high incidence of respiratory complications; however, some occur earlier and more frequently depending on the level of injury.

- Abstract
The Spinal Cord Injury Model Systems of Care have served a unique role in the provision of integrated and coordinated care for persons with spinal cord injuries (SCI), and in collaborative research efforts to advance available technologies. Although the basic mission of the model systems remains viable, contemporary issues and trends indicate that the model systems concept ought to be expanded in terms of roles and functions to meet current needs.

50. Intermittent catheterization in women with spinal cord injury-three decades of experience.

Jackson AB
- Abstract
Removal of an indwelling catheter and the initiation of intermittent catheterization (IC) has become a standard urological goal over the past decades. While realistic for men it is more difficult for women, mainly due to their anatomical differences and lack of development of a satisfactory external collection device. Thus, the evaluation for IC as a bladder management method must involve a different approach for women with spinal cord injury (SCI) than their male counterparts. Key components of the evaluation include the woman's functional abilities, attendant care, motivation, neurological bladder type (i.e., reflexive versus areflexive) along with maintenance of social continence and stable renal function. It has been shown that women tend to have less urological complications and renal deterioration than men, no matter what method of bladder management they we. Advances in urological pharmacology, diversionary surgeries and neural blocks have greatly contributed to successful bladder manipulation for self-IC.
