Dietary intake and adherence to the 2010 Dietary Guidelines for Americans among individuals with chronic spinal cord injury: A pilot study

Objective

To investigate dietary intake and adherence to the 2010 Dietary Guidelines for Americans in individuals with chronic spinal cord injury (SCI) and able-bodied individuals.

Design

A pilot study of dietary intake among a sample of individuals with SCI >1 year ago from a single site compared with able-bodied individuals.

Participants/methods

One hundred black or white adults aged 38–55 years old with SCI >1 year and 100 age-, sex-, and race-matched adults enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) study. Dietary intake was assessed by the CARDIA dietary history. Linear regression analysis was used to compare dietary intake between the subjects with SCI and those enrolled in the CARDIA study. Further, adherence to the 2010 Dietary Guidelines for dairy, fruits, and vegetables, and whole-grain foods was assessed.

Results

Compared with CARDIA participants, participants with SCI consumed fewer daily servings of dairy (2.10 vs. 5.0, P < 0.001), fruit (2.01 vs. 3.64, P = 0.002), and whole grain foods (1.20 vs. 2.44 P = 0.007). For each food group, fewer participants with SCI met the recommended servings compared with the CARDIA participants. Specifically, the participants with SCI and in CARDIA who met the guidelines were, respectively: dairy, 22% vs. 54% (P < 0.001), fruits and vegetables 39% vs. 70% (P = 0.001), and whole-grain foods 8% vs. 69.6% (P = 0.001).

Conclusions

Compared with able-bodied individuals, SCI participants consumed fewer daily servings of fruit, dairy, and whole grain foods than proposed by the 2010 Dietary Guideline recommendations. Nutrition education for this population may be warranted.     

Comparison of nutritional intake between individuals with acute and chronic spinal cord injury

Objective

To compare the nutritional intake of patients with acute and chronic spinal cord injury (SCI).

Design

Cross-sectional, observational study.

Setting

Spinal cord unit.

Methods

Twelve in-house patients of a spinal cord unit with acute SCI and paralysis duration of 5.3 ± 2.5 months (acute group) were compared with 12 subjects with chronic SCI (chronic group) with lesion duration of 55.5 ± 21.0 months. All subjects recorded their nutritional intake for 7 days, which was analyzed for intake of energy, proteins, fat, carbohydrates, vitamins, mineral nutrients, fluid, and dietary fiber. Resting energy expenditure (REE) and total body fat were also determined.

Results

The chronic group showed a significantly higher total body fat content compared to the acute group (19.4 ± 3.8 vs. 15.7 ± 4.3%). All other parameters were not significantly different between groups. Both groups ingested excessive fat and insufficient amounts of carbohydrates compared with common nutritional recommendations. Low intakes of vitamins C, D, E, biotin, folic acid, as well as potassium and iron were found.

Conclusions

No differences were found in the nutritional intakes of two comparable groups of subjects with acute and chronic SCI. Independent of lesion duration, subjects with SCI showed considerable deviations from the general accepted nutritional recommendations concerning macro- and micronutrients intake. Professional nutritional education for persons with SCI should start as soon as possible after injury to prevent nutrition-related secondary complications like cardiovascular diseases. Periodic determinations of body fat content and REE combined with a physical activity program might be helpful as well.

Community exercise for individuals with spinal cord injury with inspiratory muscle training: A pilot study

Context/Objective: Respiratory disorders are a common cause of rehospitalization, and premature death in individuals with spinal cord injuries (SCI). Respiratory training combined with community exercise programs may be a method to reduce secondary complications in this population.Objective: The present study explores the inclusion of inspiratory muscle training (IMT) in an existing community exercise program.Design: Case series.Setting: Community.Participants: Participants (N = 6) completed the exercise program. Five were male and one was female; four reported incomplete injuries, and two reported complete injuries; four had cervical injuries, and two had thoracic injuries. The average age was 33 years (SD = 18.6) and time since injury was 7 years (SD = 4.0).Interventions: Participants completed an 8-week program, once-per-week for 4 h that included a circuit of resistance training, aerobic exercise, trunk stability, and education. IMT was completed as a home exercise program.Outcome Measures: Transfer test, T-shirt test, four-directional reach, four-directional trunk strength, weekly training diaries, and a subjective interview.Results: Twenty-eight training logs were collected. All measures improved: transfer test (mean = −14.62, SD = 7.00 s), T-shirt test (mean = −7.83, SD = 13.88 s), four-directional reach (mean = 3.75, SD = 8.06 in) and hand-held dynamometer (mean = 6.73, SD = 8.02 kg). Individuals reported a positive impact of the program.Conclusions: This pilot study demonstrated community exercise with IMT use may have positive impact on functional measures for people with SCI who are vulnerable to respiratory compromise. Continued education may increase successful health outcomes.Trial Registration: {"type":"clinical-trial","attrs":{"text":"NCT03743077","term_id":"NCT03743077"}}NCT03743077.     

Weight gain following spinal cord injury: a pilot study

Study design

Retrospective chart review.

Objective

To define the temporal course of weight gain in persons with new spinal cord injury (SCI), and to identify predictors of weight gain in this population.

Setting

A United States Department of Veterans Affairs (VA) SCI Unit.

Methods

A retrospective chart review in a VA SCI Unit was conducted. Participants (n = 85) included all persons with new SCI completing initial rehabilitation at the center between 1998 and 2006. Outcome measures were mean change in body mass index (BMI) between rehabilitation admission and final follow-up, time of greatest BMI change, and distribution of participants by BMI classification. These measures were also examined relative to SCI level, American Spinal Injury Association Impairment Scale (AIS) grade, primary mode of mobility, and age at rehabilitation admission.

Results

Mean BMI increased by 2.3 kg/m² between rehabilitation admission (mean 45 days post-injury) and final follow-up (mean 5 years post-injury). The distribution of participants shifted from lower BMI classifications at rehabilitation admission to higher BMI classifications at final follow-up. For participants transitioning from normal to overweight or obese, the greatest increase occurred during the first year after acute rehabilitation. Neurological level, impairment category, primary mode of mobility, and age at rehabilitation admission did not significantly predict BMI change. BMI at rehabilitation admission correlated significantly with BMI at final follow-up (P < 0.0005).

Conclusions

These findings confirm a significant increase in BMI after new SCI and suggest that persons with new SCI are at greatest weight gain risk during the first year following acute rehabilitation.     

Guidelines for management of pediatric acute hyperextension spinal cord injury

Pediatric acute hyperextension spinal cord injury (SCI) named as PAHSCI by us, is a special type of thoracolumbar SCI without radiographic abnormality and highly related to back-bend in dance training, which has been increasingly reported. At present, it has become the leading cause of SCI in children, and brings a heavy social and economic burden. Both domestic and foreign academic institutions and dance education organizations lack a correct understanding of PAHSCI and relevant standards, specifications or guidelines. In order to provide standardized guidance, the expert team formulated this guideline based on the principles of science and practicability, starting from the diagnosis, differential diagnosis, etiology, admission evaluation, treatment, complications and prevention. This guideline puts forward 23 recommendations for 14 related issues.     

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.     

Exploring daily blood pressure fluctuations and cardiovascular risk among individuals with motor complete spinal cord injury: a pilot study

Background: Clinically silent autonomic dysfunction with bowel and bladder care, are postulated to contribute to cardiovascular disease after chronic spinal cord injury (SCI).

Objective: We describe the frequency and severity of dysreflexic episodes, termed transient blood pressure elevations (T-BPE) over 48 hours in adults with cervical or high-thoracic motor-complete SCI.

Setting: Tertiary SCI Rehabilitation Centre in Toronto, Canada.

Participants: Individuals with chronic SCI, C1-T3 AIS A or B, >1 year post-injury, living in the community (n=19).

Outcome Measures: Data were obtained via 48-hour ambulatory blood pressure (BP) and heart rate (HR) monitoring, with data captured at 10-minute intervals and a concurrent diary describing activities of daily living, and bladder/bowel routines. T-BPE were defined as a?≥?40 mmHg elevation in systolic blood pressure (SBP) above the participant's supine baseline. Severe (≥ 60–79 mmHg) and Extreme ≥80 mmHg elevations in SBP were described.

Results: Thirteen participants experienced T-BPE within the assessment period, with 7/13 experiencing “severe”, and 3/13 experiencing “extreme” SBP elevations. The median number of T-BPE was 8 (IQR?=?3), and the mean?±?SD SBP during T-BPE was 150?±?16 mmHg, These T-BPE were verified as dysreflexic events using a conservative definition of a >40 mmHg increase in SBP, with a concurrent 10 bpm decrease in HR, above the 48-hour average SBP, yielding 12/19 participants with T-BPE.

Conclusions: T-BPE were frequent, often with severe or extreme elevations in SBP, despite few reported symptoms. Recognition and management of these dysreflexic events associated with T-BPE are needed, which may ameliorate cardiovascular disease risk.     

Cardiovascular disease risk in individuals with chronic spinal cord injury: Prevalence of untreated risk factors and poor adherence to treatment guidelines

Background/Objective: Cardiovascular disease (CVD) is currently the leading cause of mortality among individuals living with chronic spinal cord injury (SCI). The purpose of this study is to: 1) Describe the prevalence of CVD risk factors including dyslipidemia (DYS), hypertension (HTN) and type II diabetes mellitus (DM) in patients with chronic SCI; 2) Report the frequency of individuals recommended for diagnostic testing, as per current Canadian CVD diagnostic guidelines; and 3) Report the frequency of individuals receiving guideline-derived appropriate therapy for these risk factors.

Methods: Adults with a chronic, stable SCI (n?=?91) were included in this study. Medical histories, current medications, blood serum analyses and blood pressures were collected and compared to current Canadian CVD diagnostic guidelines to assess for DYS, HTN and DM.

Results: Of the 81 participants with blood serum analyses, 10 (14.7%) of 23 (28.4%) individuals meeting diagnostic criteria for DYS were not taking appropriate statin medication and 2 (2.5%) of 7 (8.6%) individuals meeting diagnostic criteria for DM were not taking appropriate DM medication. Of the 91 participants having BP measurements, 13 (14.3%) of 26 (28.6%) individuals meeting diagnostic criteria for HTN were not taking appropriate BP medication.

Conclusions: In addition to a high prevalence of CVD risk factors among individuals with chronic SCI, there is also evidence of poor adherence to diagnostic and treatment guidelines for DYS, HTN and DM. The study results highlight an important gap between the observed prevalence of disease and the low rates of screening and guideline adherence in the SCI population.     

Effect of acute intermittent hypoxia on motor function in individuals with chronic spinal cord injury following ibuprofen pretreatment: A pilot study

Introduction: Acute intermittent hypoxia (AIH) enhances lower extremity motor function in humans with chronic incomplete spinal cord injury (SCI). AIH-induced spinal plasticity is inhibited by systemic inflammation in animal models. Since SCI is frequently associated with systemic inflammation in humans, we tested the hypothesis that pretreatment with the anti-inflammatory agent ibuprofen enhances the effects of AIH.

Methods: A randomized, double-blinded, placebo-controlled crossover design was used. Nine adults (mean age 51.1?±?13.1 years) with chronic motor-incomplete SCI (7.7?±?6.3 years post-injury) received a single dose of ibuprofen (800?mg) or placebo, 90 minutes prior to AIH. For AIH, 9% O₂ for 90 seconds was interspersed with 21% O₂ for 60 seconds. Maximal voluntary ankle plantar flexion isometric torque was assessed prior to, and at 0, 30, and 60 minutes post-AIH. Surface electromyography (EMG) of plantar flexor muscles was also recorded.

Results: Torque increased significantly after AIH at 30 (P?=?0.007; by ～20%) and 60 (P?2?=?0.17, P?2?=?0.17, P?Conclusions: AIH systematically increased lower extremity torque in individuals with chronic incomplete SCI, but there was no significant effect of ibuprofen pretreatment. Our study re-confirms the ability of AIH to enhance leg strength in persons with chronic incomplete SCI.     

Secondary health conditions and disability among people with spinal cord injury: A prospective cohort study

Objective: To examine how secondary health conditions (SHCs) that develop early after a spinal cord injury (SCI) are related to disability over time.Design: Prospective cohort study.Setting: Two spinal units in New Zealand (Burwood Spinal Unit and Auckland Spinal Rehabilitation Unit).Participants: Between 2007 and 2009, 91 people participated in three telephone interviews approximately 6, 18, and 30 months after the occurrence of a SCI.Outcome measures: SHCs were measured using 14 items derived from the Secondary Complications Survey. Disability was measured using the 12-item World Health Organization Disability Assessment Schedule 2.0. Linear regression analyses were performed to investigate associations between SHCs at 6 months and disability at each assessment point.Results: The most prevalent SHCs were leg spasms, constipation, back pain, pain below the level of SCI, and shoulder pain. Constipation, urinary tract infection, and headaches at 6 months post-SCI were associated with significantly higher levels of disability at each subsequent follow-up, independent of age, sex and SCI impairment. Back pain, and pain below the SCI, at 6 months were associated with significantly greater disability at 18 months, and difficulty coughing at 6 months was associated with significantly greater disability at 30 months.Conclusion: The experience of specific SHCs in the first 6 months after an SCI is related to greater long-term disability. In order to reduce the disability burden of people with SCI, efforts should be directed toward early prevention of these SHCs.     

Environmental barriers and subjective health among people with chronic spinal cord injury: A cohort study

Abstract

Objective

Although previous studies have found environmental barriers to be associated with social participation and life satisfaction after spinal cord injury (SCI), few studies exist reporting their effects on subjective health after SCI. Our purpose was to identify the prevalence of perceived environmental barriers and their effects on subjective health in persons with chronic SCI who completed two repeated measurements during a 5-year longitudinal study.

Design

This is a prospective cohort study. Environmental barriers were measured at baseline by the Craig Hospital Inventory of Environmental Factors-Short Form. Subjective health was measured at baseline and 5-year follow-up by days of physical and mental health not good. Other control variables included sex, race, age at injury, years since injury, and injury severity at baseline.

Setting

Data were collected at a specialty hospital and analyzed at a medical university in the Southeastern USA.

Participants

A total of 1635 participants completed both baseline and follow-up surveys.

Results

Twenty per cent of participants reported at least one policy barrier, 46% at least one physical and structural barrier, 22% at least one attitudinal and support barrier, 26% at least one barrier to services and assistance, and 13% at least one barrier at work or school. After controlling for sex, race, age at injury, years since injury, and injury severity, the physical and structural barriers, and services and assistance barriers measured at baseline significantly predicted subjective physical and mental health measured at follow-up.

Conclusion

Environmental barriers are prevalent among people with chronic SCI. They are important predictors for future subjective health.

Reliability and validity of the function in sitting test among non-ambulatory individuals with spinal cord injury

Context: Trunk impairment among non-ambulatory individuals with spinal cord injury (SCI) reduces the ability to maintain a functional sitting position and perform activities of daily living. Measuring functional sitting balance is complex and difficult in a clinical setting. The function in sitting test (FIST) is a clinical measure that includes the assessment of all the components of sitting balance. The purpose of this study is to assess the reliability and validity of the 14-item FIST among non-ambulatory individuals with SCI.Participants: Twenty-six individuals with chronic SCI.Outcome measures: Participants were evaluated with the FIST, the modified Functional Reach Test (lateral and forward mFRT) and a posturography assessment (virtual time to contact – VTC). The FIST was re-assessed during a second study visit 12 weeks later. Test-retest reliability was evaluated using intraclass coefficient correlation (ICC), the minimal detectable change (MDC) was calculated and the internal consistency reliability was assessed using Cronbach''s coefficient-α. Concurrent validity of the FIST was also tested with the mFRT and the VTC.Results: Test-retest reliability was found to be excellent (ICC = 0.95) with a MDC of 4. The internal consistency was satisfactory (0.81). Moreover, the FIST correlates with the lateral mFRT (r = 0.64, P = 0.001) but not with the forward mFRT and the VTC.Conclusion: These observations provide evidence that the FIST is a reliable clinical measure with partially established validity for non-ambulatory individuals with SCI. Further studies are needed to strengthen the validity of the FIST and explore this measure in a larger sample.     

Examining implicit bias of physicians who care for individuals with spinal cord injury: A pilot study and future directions

Context

Despite evidence that healthcare providers have implicit biases that can impact clinical interactions and decisions, implicit bias among physicians caring for individuals with spinal cord injury (SCI) has not been examined.

Objective

Conduct a pilot study to examine implicit racial bias of SCI physicians and its association with functioning and wellbeing for individuals with SCI.

Design

Combined data from cross-sectional surveys of individuals with SCI and their SCI physicians.

Setting

Four national SCI Model Systems sites.

Participants

Individuals with SCI (N = 162) and their SCI physicians (N = 14).

Outcome measures

SCI physicians completed online surveys measuring implicit racial (pro-white/anti-black) bias. Individuals with SCI completed questionnaires assessing mobility, physical independence, occupational functioning, social integration, self-reported health, depression, and life satisfaction. We used multilevel regression analyses to examine the associations of physician bias and outcomes of individuals with SCI.

Results

Physicians had a mean bias score of 0.62 (SD = 0.35), indicating a strong pro-white/anti-black bias. Greater physician bias was associated with disability among individuals with SCI in the domain of social integration (odds ratio = 4.80, 95% confidence interval (CI) = 1.44, 16.04), as well as higher depression (B = 3.24, 95% CI = 1.06, 5.41) and lower life satisfaction (B = −4.54, 95% CI= −8.79, −0.28).

Conclusion

This pilot study indicates that SCI providers are susceptible to implicit racial bias and provides preliminary evidence that greater implicit racial bias of physicians is associated with poorer psychosocial health outcomes for individuals with SCI. It demonstrates the feasibility of studying implicit bias among SCI providers and provides guidance for future research on physician bias and patient outcomes.

Elevated levels of IgA and IgG2 in individuals with chronic spinal cord injury

ObjectivesTo determine circulating levels of antibodies (IgA, IgM, IgG1-4) in individuals with SCI as compared to uninjured individuals.Study DesignProspective, observational study.SettingOutpatient clinic of a Department of Physical Medicine and Rehabilitation and research institute in an academic medical center.ParticipantsIndividuals with chronic (≥ 1 year from injury) SCI and uninjured individuals.Outcome MeasuresSerum antibody titers were determined by commercial multiplex ELISA.ResultsBlood samples were collected from individuals with chronic SCI (N = 29, 83% males) and uninjured individuals (N = 25, 64% males). Among participants with SCI, the distribution of American Spinal Injury Association Impairment Scale (AIS) grades was: A (n = 15), B (n = 2), C (n = 4), D (n = 8). Neurological levels of injury were: cervical (n = 17), thoracic (n = 10), and lumbar (n = 2). IgA levels were significantly elevated in participants with SCI compared to uninjured participants (median: 1.98 vs. 1.21 mg/ml, P < 0.0001), with levels most elevated in individuals with motor complete injuries compared to uninjured participants (P < 0.0003). IgG2 antibodies were also significantly elevated in participants with SCI compared to uninjured participants (median: 5.98 vs. 4.37 mg/ml, P < 0.018).ConclusionsTo our knowledge, this study provides the first evidence of elevated IgA, the antibody type most prevalent at respiratory, genitourinary and gastrointestinal tracts, common sites of infections in individuals with SCI. IgG2 levels were also elevated in individuals with SCI. These data support further investigations of IgA and other antibody types in individuals with chronic SCI, which may be increasingly important in the context of emerging novel infectious diseases such as SARS-CoV-2.

A brief fall prevention intervention for manual wheelchair users with spinal cord injuries: A pilot study

Objective: To conduct a pilot study of an intervention to decrease fall incidence and concerns about falling among individuals living with Spinal Cord Injury who use manual wheelchairs full-time.

Design: Pre/post. After a baseline assessment, a structured intervention was implemented. The assessment protocol was repeated 12 weeks after the baseline assessment.

Setting: Research laboratory and community.

Participants: 18 individuals living with SCI who use a manual wheelchair full-time with an average age of 35.78?±?13.89 years, lived with SCI for 17.06?±?14.6 years; 61.1% were female.

Intervention: A 1:1, 45 minute, in-person intervention focused on factors associated with falls and concerns about falling: transfers skills and seated postural control.

Outcome measures: Participants reported fall incidence and completed the Spinal Cord Injury Fall Concerns Scale, Community Participation Indicators and the World Health Organization Quality of Life – short version (WHOQOL-BREF). Transfer quality was assessed with the Transfer Assessment Instrument (TAI) and seated postural control with the Function In Seating Test (FIST).

Results: Recruitment, assessment and delivery of the intervention were successfully completed. After exposure to the intervention, fall incidence significantly decreased, (P?=?0.047, d_{z ?}=?0.507) and FIST scores improved (P?=?0.035, d_z? =?0.54). Significant improvements were also found in the WHOQOL-BREF Physical (P?=?0.05, d_{z ?}=?1.566) and Psychological (P?=?0.040, d_{z ?}=?0.760) domains.

Conclusion: The feasibility of the structured intervention was established and the intervention has the potential to reduce fall incidence and improve quality of life among individuals living with SCI who use a wheelchair. Appropriately powered randomized controlled trials of the program are warranted.     

The association between dietary inflammatory index and psychological profile among men with spinal cord injury

ObjectiveThe present study was designed to examine the relationship between the dietary inflammatory index (DII) and depression, anxiety and stress in Iranian men with spinal cord injury (SCI).DesignCross-sectional study.SettingMottahary SCI clinic, Isfahan, Iran.ParticipantsThe current study was conducted on 150 men with SCI aged 40–65 years.Outcome MeasuresDietary data were collected using a semi-quantitative 148 item food frequency questionnaire (FFQ). The Depression, Anxiety, Stress Scale-21 (DASS-21) was used to assess the psychological profile of the participants.ResultsThe DII score ranged from −3.62 to 4.02. Overall, 34% of study participants had at least mild levels of depression and anxiety symptoms and 25% had at least mild levels of stress symptoms. A one-unit increase in the DII was significantly associated with higher scores of depressive symptoms (β = 1.31, 95% CI 0.44–2.18; P = 0.003). Also, a one-unit increase in the DII was associated with higher odds of having at least mild depressive symptoms (OR = 1.77, 95% CI 1.17, 2.67; P = 0.007). No significant association was found between the DII and anxiety and stress.ConclusionThe present study indicated that a higher DII score is associated with higher odds of depressive symptoms in men with SCI. These initial findings highlight the crucial role of the inflammatory potential of diet in the mental health of subjects with SCI. Future prospective studies are warranted to confirm these findings.
