- Abstract
Introduction Pneumonia is one of the leading complications and causes of death after a spinal cord injury (SCI). After a cervical or thoracic lesion, impairment of the respiratory muscles decreases respiratory function, which increases the risk of respiratory complications. Pneumonia substantially reduces patient’s quality of life, may prolong inpatient rehabilitation time, increase healthcare costs or at worse, lead to early death. Respiratory function and coughing can be improved through various interventions after SCI, but the available evidence as to which asp

- Abstract
INTRODUCTION: Pneumonia is one of the leading complications and causes of death after a spinal cord injury (SCI). After a cervical or thoracic lesion, impairment of the respiratory muscles decreases respiratory function, which increases the risk of respiratory complications. Pneumonia substantially reduces patient's quality of life, may prolong inpatient rehabilitation time, increase healthcare costs or at worse, lead to early death. Respiratory function and coughing can be improved through various interventions after SCI, but the available evidence as to which aspect of respiratory care should be optimised is inconclusive. Furthermore, ability of respiratory function parameters to predict pneumonia risk is insufficiently established. This paper details the protocol for a large-scale, multicentre research project that aims to evaluate the ability of parameters of respiratory function to predict and understand variation in inpatient risk of pneumonia in SCI. METHODS AND ANALYSIS: RESCOM, a prospective cohort study, began recruitment in October 2016 across 10 SCI rehabilitation centres from Australia, Austria, Germany, the Netherlands and Switzerland. Inpatients with acute SCI, with complete or incomplete cervical or thoracic lesions, 18 years or older and not/no more dependent on 24-hour mechanical ventilation within the first 3 months after injury are eligible for inclusion. The target sample size is 500 participants. The primary outcome is an occurrence of pneumonia; secondary outcomes include pneumonia-related mortality and quality of life. We will use the longitudinal data for prognostic models on inpatient pneumonia risk factors. ETHICS AND DISSEMINATION: The study has been reviewed and approved by all local ethics committees of all participating centres. Study results will be disseminated to the scientific community through peer-reviewed journals and conference presentations, to the SCI community, other stakeholders and via social media, newsletters and engagem

- Abstract
__Abstract__ Survival rates and medical care following spinal cord injury (SCI) have improved largely over the last decades and have resulted in a decline of mortality during the first 2 years after injury. The mortality rates in the period thereafter have not changed substantially. Respiratory diseases, particularly lower tract respiratory infections, remain a common cause of early death and hospitalization in persons with chronic SCI. Therefore, in this thesis we focused on respiratory function after SCI. We studied changes in respiratory function, the prevalence of impaired respiratory function and consequences in the early years after inpatient rehabilitation. In addition, we studied the effects of a specific respiratory training program added to the usual inpatient rehabilitation treatment. For the first part of this thesis we used data of a Dutch multicenter prospective cohort study (the Umbrella and SPIQUE project). For the second part we conducted a multicenter randomized controlled trial (RCT) on the effects of resistive inspiratory muscle training (RIMT).

- Abstract
1 augustus 2013, Item does not contain fulltext, OBJECTIVE: To describe changes in pulmonary function (PF) during the 5 years after inpatient rehabilitation in persons with spinal cord injury (SCI) and to study potential determinants of change. DESIGN: Prospective cohort study. SETTING: Eight rehabilitation centers with specialized SCI units. PARTICIPANTS: Persons with SCI (N=180). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: PF was determined by forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) as a percentage of the predicted value, at the start of rehabilitation, at discharge, and 1 and 5 years after discharge from inpatient rehabilitation. The population was divided into 3 subgroups on the basis of whether their PF declined, stabilized, or improved. RESULTS: FVC improved on average 5.1% over the whole period between discharge of inpatient rehabilitation and 5 years thereafter, but changes differed largely between persons. FVC declined in 14.9% of the population during the first year after discharge. During this year, body mass index, inspiratory muscle strength, change in peak power output, and change in peak oxygen uptake differed significantly between subgroups. FVC declined in 28.3% of the population during the following 4 years, but no differences were found between the subgroups for this period. Subgroups based on changes in FEV1 differed only with respect to change in peak oxygen uptake the first year after discharge. CONCLUSIONS: In our study, many persons with SCI showed a decline in PF, larger than the normal age-related decline, during the 5 years after inpatient rehabilitation. Results suggest that a decline in PF during the first year after inpatient rehabilitation is associated with higher body mass index, lower inspiratory muscle strength, and declined physical fitness.

- Abstract
Multicenter cross-sectional study. To determine the prevalence of parenthood in long-term wheelchair-dependent persons who sustained a spinal cord injury (SCI) during their reproductive years. Secondary aims were to (1) explore patient-specific and disease-related factors associated with parenthood after SCI; and (2) quantify fertility aids used by men with SCI. Eight specialized SCI rehabilitation centers in the Netherlands. Questionnaires and physical examination were applied in 255 persons with SCI. Prevalence rates of parenthood among the general Dutch population were used for comparison. Logistic regression analyses were used to explore factors associated with parenthood after SCI. Prevalence of parenthood in SCI was 50% in men and 45% in women, which was significantly (P< 0.05) lower than rates in the general population (74% in men and 81% in women). Among the parents with SCI, most (66% of males and 72% of females) of them had children after SCI. Parenting children after SCI was associated with partnership (OR = 14.5, P < .001 [men]; OR = 3.7, P= .05 [women]), normal micturition (OR = 4.9, P= .02 [men]), incomplete lesion (OR = 5.4, P= .03 [women]), and paraplegia (OR = 7.3, P= .02 [women]). The most frequently used methods for ejaculation and fertilization were electroejaculation (29%) and intracytoplasmatic sperm injection (23%). Prevalence of parenthood in SCI persons is low. However, half of the persons with SCI do become parents, with most doing so following SCI. Demographic and disease-related factors may contribute to this.

- Abstract
Study design:A prospective cohort study. Objectives:To study the longitudinal relationship between objectively measured everyday physical activity level, and physical fitness and lipid profile in persons with a recent spinal cord injury (SCI).Setting:A rehabilitation centre in the Netherlands and the participant's home environment. Methods:Data of 30 persons with a recent SCI were collected at the start of active rehabilitation, 3 months later, at discharge from inpatient rehabilitation, and 1 year after discharge. Physical activity level (duration of dynamic activities as % of 24 h) was measured with an accelerometry-based activity monitor. Regarding physical fitness, peak oxygen uptake (VO2peak) and peak power output (POpeak) were determined with a maximal wheelchair exercise test, and upper extremity muscle strength was measured with a handheld dynamometer. Fasting blood samples were taken to determine the lipid profile. Results:An increase in physical activity level was significantly related to an increase in VO2peak and POpeak, and an increase in physical activity level favourably affected the lipid profile. A nonsignificant relation was found with muscle strength. Conclusion:Everyday physical activity seems to have an important role in the fitness and health of persons with a recent SCI. An increase in physical activity level was associated with an increase in physical fitness and with a lower risk of cardiovascular disease.Spinal Cord advance online publication, 6 December 2011; doi:10.1038/sc.2011.152.

- Abstract
OBJECTIVE: To investigate the reliability of the Dutch version of the Spinal Cord Injury-Interventions Classification System. DESIGN: Descriptive study. SETTING: Three Dutch spinal cord injury facilities. PARTICIPANTS: Six physical therapists, 6 occupational therapists, and 3 sports therapists. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: A 4- or 5-digit code was used to score videotaped interventions on 2 occasions in terms of level, category, and type of intervention. We examined the percentage of correctly assigned interventions (agreement between the researcher and the participants), agreement between the first and second measurements (intrarater reliability), and agreement between the therapists of the same discipline (interrater reliability). RESULTS: A total of 252 interventions were assigned. The agreement between the researcher and the participants was good: the percentage of correct interventions was high at both measurements (91.7% and 94.4%). Intrarater agreement was also good (90.9%). The interrater agreement within the physical therapists and the occupational therapists was high at both occasions (mean, 92.3% and 87.0%, respectively), but lower within the sports therapists (mean, 69.3%). CONCLUSIONS: The study provided first evidence for reliability of the classification system. Further research is needed to confirm these results and to test the reliability of other language versions. Copyright © 2009 by the American Congress of Rehabilitation Medicine [ABSTRACT FROM AUTHOR]

- Abstract
Objective: To describe the development of a classification for therapeutic activities in clinical spinal cord injury (SCI) rehabilitation.Design: Descriptive study including a modified Delphi consensus method.Setting: Specialized SCI units of 10 rehabilitation facilities.Participants: Thirty physical therapists, occupational therapists, and sports therapists from 10 Dutch and Flemish SCI centers.Main outcome measures: Identification of the levels, categories, and interventions; level of agreement among experts with (1) definitions, (2) terminology, (3) relevance, and (4) completeness of the classification (consensus considered sufficient if 80% or more agree).Results: The classification comprises three levels of functioning: basic functions, basic activities, and complex activities. The three levels comprise 28 categories within which interventions are listed. Sufficient consensus was obtained for the definitions of the three levels (range, 87%-100%). Percentages of consensus for the terminology used and the completeness of the categories ranged from 75% to 100%. The perceived relevance of the categories for everyday work varied per discipline.Conclusion: A potentially useful classification was developed to record clinical treatment sessions in physical therapy, occupational therapy, and sports therapy for persons with SCI. The classification is currently being tested in ongoing research. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Due to the majority of males within the population of persons with spinal cord injuries (SCI), a male-oriented perception of persons with SCI might affect care provision in the way of prioritizing male needs., Objective: The objective of this cross-sectional study is to describe the patient experience of persons with SCI by gender., Methods: This study was based on the International Spinal Cord Injury Survey with 12,588 participants from 22 countries. An interval-based patient experience score was attained by partial credit model. Regression analysis was used in exploring the association between patient experience and gender., Results: Participants reported very good and good patient experience. Respectful treatment was reported by 78 % of participants; clear explanations by 75 %; involvement in decision-making by 71 %; satisfaction with services by 62 %. The average patient experience score was equal among males and females (average: 64, range: 0-100), with the highest score in participants from the USA (78) and the lowest - in Morocco (44). Patient experience score was not associated with gender. Females had lower odds of reporting better decision-making involvement, yet higher odds of better satisfaction. Older participants, with higher household income and better self-rated health, had lower odds of being satisfied., Conclusion: The majority of persons with SCI rated their experience as good or very good. Females were more likely to report higher satisfaction with services and lower involvement in decision-making. For other patient experience categories and the overall patient experience score, no association with gender was found., Competing Interests: Declaration of competing interest The authors declare no conflict of interest relevant to this article., (Copyright © 2024 The Authors.

- Abstract
Objective: To describe the occurrence of pneumonia in individuals with acute spinal cord injury (SCI) and identify its key predictors., Design: Multi-centric, longitudinal cohort study., Setting: 10 specialized SCI rehabilitation units in Europe and Australia., Participants: Eligible were 902 men and women with acute SCI, aged 18 years or older, with cervical or thoracic lesions and not dependent on 24-hour mechanical ventilation; 503 participated in the study (N=503)., Interventions: Not applicable., Main Outcome Measures: We assessed demographics and lesion related parameters at study entry, and any pneumonia events throughout inpatient rehabilitation. Respiratory function, decubitus, and urinary tract infections were assessed at 1, 3, and 6 months post injury as well as at discharge from inpatient rehabilitation. Time to event (pneumonia) analyses were done using the Kaplan-Meier method, and potential predictors for pneumonia were analyzed with multivariable survival models., Results: Five hundred three patients with SCI were included, with 70 experiencing at least 1 pneumonia event. 11 participants experienced 2 or more events during inpatient rehabilitation. Most events occurred very early after injury, with a median of 6 days. Pneumonia risk was associated with tetraplegia (hazard ratio [HR]=1.78; 95% confidence interval [CI] 1.00-3.17) and traumatic etiology (HR=3.75; 95% CI 1.30-10.8) American Spinal Injury Impairment Scale (AIS) A (HR=5.30; 95% CI 2.28-12.31), B (HR=4.38; 95% CI 1.77-10.83), or C (HR=4.09; 95% CI 1.71-9.81) lesions. For every 10 cmH
2 O increase in inspiratory muscle strength, pneumonia risk was reduced by 13% (HR=0.87; 95% CI 0.78-0.97)., Conclusion: Pneumonia is a major complication after SCI with the highest incidence very early after injury. Individuals with traumatic or AIS A, B, or C tetraplegia are at highest risk for pneumonia., (Copyright © 2023 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

- Abstract
Study Design: Longitudinal cohort study., Objectives: Examine the longitudinal association between mobility and level of physical activity (PA) and explore which other factors are also associated with level of PA in ambulatory people with Spinal Cord Injury (SCI) during the first-year post-inpatient rehabilitation., Setting: Three SCI-specialized rehabilitation centers and the Dutch community., Methods: Forty-seven adults with recent SCI and ambulatory function were included. All had motor incomplete lesions, 49% had tetraplegia, and the mean age was 55 ± 13 years. Duration of accelerometry-based all-day PA and self-reported level of mobility, exertion of walking, pain, fatigue, depressive mood symptoms, fear of falling, exercise self-efficacy, and attitude toward PA were measured just before discharge from inpatient rehabilitation and 6 and 12 months after discharge. All data were longitudinally analyzed using generalized estimating equations analyses. Models were corrected for age, lesion level, and time since injury., Results: Mobility was longitudinally associated with level of PA (beta: 4.5, P < 0.001, R
2 : 41%). In addition, lower levels of exertion of walking (beta: -5.6, P < 0.001), fear of falling (beta: -34.1, P < 0.001), and higher levels of exercise self-efficacy (beta: 2.3, P = 0.038) were associated with higher levels of PA. Exertion of walking and fear of falling were associated with level of PA independent of mobility., Conclusions: Mobility, exertion of walking, fear of falling, and exercise self-efficacy seem to be correlates of level of PA in ambulatory people with SCI during the first year after inpatient rehabilitation. Targeting these factors using an interdisciplinary approach may enhance levels of PA in this population., (© 2024.

- Abstract
Aflatoxins are toxic fungal metabolites that occur naturally in the field among cereals, oilseeds, and nuts that may increase during storage. Texas grown maize, commonly referred as corn, has some of the highest aflatoxin levels in the US. In 2011, the Office of the Texas State Chemist (OTSC) collaborated with the Risk Management Agency (RMA) of the United States Department of Agriculture (USDA) and the Texas grain industry to implement the state's first co-regulation governance option to manage aflatoxin risk. Co-regulation is a form of risk management that relies upon a government-private partnership in regulation; utilizing government-backed codes of practice that result in a more connected and transparent marketplace. To measure the economic benefit of co-regulation to manage aflatoxin risk, interviews were conducted among twenty-seven participants in the OTSC aflatoxin co-regulation program who represented 31% of the grain companies that handled maize contaminated by aflatoxin according to Texas Commercial Feed Rules. A comparative approach was used by gathering evidence from 2010 to 2018, in order to evaluate the results before and after the OTSC implemented its co-regulation strategy. The results were evaluated by using the data gathered from the interviews to measure the specific costs and benefits incurred by producers and grain handlers. The findings were modeled in the form of an income statement. From the income statement, the total economic benefit of the One Sample Strategy in 2018 was $14,572,180. This study provides a more realistic characterization of cost drivers associated with aflatoxin risk management and counters exaggerated economic losses associated with aflatoxin in maize from prior studies., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Timothy Herrman, Kelsey Postma, and Mary Sasser are employed, or have been employed, by the Office of the Texas State Chemist, which oversaw the implementation and administration of the Feed and Fertilizer Control Service’s One Sample Strategy, the primary subject of this paper. As authors, we are reporting on our work regulating aflatoxin contamination.

- Abstract
Purpose: (1) To estimate the proportion of Dutch wheelchair users with spinal cord injury (SCI) who meet different SCI exercise guidelines; (2) to evaluate which demographic and lesion characteristics are associated with meeting these guidelines; (3) whether meeting these guidelines is associated with physical fitness and health., Materials and Methods: Based on the PASIPD questionnaire items, participants were allocated to meeting two SCI aerobic exercise guidelines, which differ in exercise load. Differences in personal, lesion, fitness, and health characteristics between groups were tested with a one-way ANOVA. Multiple regression analyses were performed to evaluate if meeting guidelines was associated with better fitness and health. Statistical significance was accepted at p < 0.05., Results: Of the 358 included participants, 63.1% met at least one aerobic exercise guideline. Being female, older age, having tetraplegia, and lower educational level were associated with a lower likelihood to meet the aerobic exercise guidelines. Meeting aerobic exercise guidelines showed a positive association with all respiratory and exercise capacity parameters. Limited associations were found between meeting exercise guidelines and health., Conclusions: Meeting exercise guidelines was associated with better respiratory functions and exercise capacity with additional fitness and some body composition benefits in higher exercise activity levels.IMPLICATIONS FOR REHABILITATIONMeeting SCI exercise guidelines are associated with better respiratory functions and exercise capacity with additional fitness and body composition benefits when higher exercising at higher activity levels, emphasizing the value and importance of regular exercise in individuals with SCI.

- Abstract
Objectives: Evidence on social inequalities in mental health of persons with physical impairments is limited. We therefore investigate associations of individual-level socioeconomic status (SES) and the country-level socioeconomic development (SED) with mental health in persons with spinal cord injury (SCI). Methods: We analyzed data from 12,588 participants of the International SCI Community Survey from 22 countries. To investigate individual-level inequalities, SES indicators (education, income, financial hardship, subjective status) were regressed on the SF-36 mental health index (MHI-5), stratified by countries. Country-level inequalities were analyzed with empirical Bayes estimates of random intercepts derived from linear mixed-models adjusting for individual-level SES. Results: Financial hardship and subjective status consistently predicted individual-level mental health inequalities. Country-level SED was inconsistently related to mental health when adjusting for individual-level SES. It however appeared that higher SED was associated with better mental health within higher-resourced countries. Conclusion: Reducing impoverishment and marginalization may present valuable strategies to reduce mental health inequalities in SCI populations. Investigations of country-level determinants of mental health in persons with SCI should consider influences beyond country-level SED, such as cultural factors., Competing Interests: The authors declare that they do not have any conflicts of interest., (Copyright © 2022 Fekete, Tough, Leiulfsrud, Postma, Bökel, Tederko and Reinhardt.)

- Abstract
Alternatively-activated, M2-like tumor-associated macrophages (TAM) strongly contribute to tumor growth, invasiveness and metastasis. Technologies to disable the pro-tumorigenic function of these TAMs are of high interest to immunotherapy research. Here we show that by designing engineered nanoliposomes bio-mimicking peroxidated phospholipids that are recognised and internalised by scavenger receptors, TAMs can be targeted. Incorporation of phospholipids possessing a terminal carboxylate group at the sn-2 position into nanoliposome bilayers drives their uptake by M2 macrophages with high specificity. Molecular dynamics simulation of the lipid bilayer predicts flipping of the sn-2 tail towards the aqueous phase, while molecular docking data indicates interaction of the tail with Scavenger Receptor Class B type 1 (SR-B1). In vivo, the engineered nanoliposomes are distributed specifically to M2-like macrophages and, upon delivery of the STAT6 inhibitor (AS1517499), zoledronic acid or muramyl tripeptide, these cells promote reduction of the premetastatic niche and/or tumor growth. Altogether, we demonstrate the efficiency and versatility of our engineered "tail-flipping" nanoliposomes in a pre-clinical model, which paves the way to their development as cancer immunotherapeutics in humans., (© 2022.

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

- Abstract
Objective: To evaluate changes in duration of physical activity (PA) and sedentary behavior (SB) from discharge to 1 year after inpatient rehabilitation in ambulatory people with spinal cord injury (SCI)., Design: Longitudinal cohort study with objective measurements of physical behavior at discharge and at 6 and 12 months post discharge., Setting: Three rehabilitation centers and the participant's home environment., Participants: Participants (N=47) with ambulatory function were consecutively recruited from the self-management and self-efficacy in patients with SCI cohort (age 18 years or older, recent SCI, expected inpatient stay ≥4wk). Mean age was 54.5±12.9 years, all had incomplete lesions, 53% were men, 49% had tetraplegia, and 51% were community ambulators at discharge., Interventions: Not applicable., Main Outcome Measures: Duration (min) of PA (summed duration of walking, cycling, running, and wheeling) and SB (sitting/lying)., Results: Mean duration of PA increased by 21 min/d (95% confidence interval, 7-35) and SB decreased by 64 min/d (95% confidence interval, -94 to -35) from discharge to 6 months after inpatient rehabilitation. No changes were found in the second half-year. One year after discharge mean PA was 116±59 min/d and mean SB was 665±121 min/d. The increase in PA was the result of an almost doubling of time spent walking. Variability in physical behavior and its change was large. Older age and lower ambulation level were associated with lower PA, lower ambulation level with higher SB, and tetraplegia was associated with a reduced increase in PA., Conclusions: At group level, duration of PA and SB improved following inpatient rehabilitation in ambulatory people with SCI. However, there were large differences between individuals. Levels 1 year after discharge were still unfavorable, particularly regarding SB., (Copyright © 2020 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.)

- Abstract
Introduction: Pneumonia is one of the leading complications and causes of death after a spinal cord injury (SCI). After a cervical or thoracic lesion, impairment of the respiratory muscles decreases respiratory function, which increases the risk of respiratory complications. Pneumonia substantially reduces patient's quality of life, may prolong inpatient rehabilitation time, increase healthcare costs or at worse, lead to early death. Respiratory function and coughing can be improved through various interventions after SCI, but the available evidence as to which aspect of respiratory care should be optimised is inconclusive. Furthermore, ability of respiratory function parameters to predict pneumonia risk is insufficiently established. This paper details the protocol for a large-scale, multicentre research project that aims to evaluate the ability of parameters of respiratory function to predict and understand variation in inpatient risk of pneumonia in SCI., Methods and Analysis: RESCOM, a prospective cohort study, began recruitment in October 2016 across 10 SCI rehabilitation centres from Australia, Austria, Germany, the Netherlands and Switzerland. Inpatients with acute SCI, with complete or incomplete cervical or thoracic lesions, 18 years or older and not/no more dependent on 24-hour mechanical ventilation within the first 3 months after injury are eligible for inclusion. The target sample size is 500 participants. The primary outcome is an occurrence of pneumonia; secondary outcomes include pneumonia-related mortality and quality of life. We will use the longitudinal data for prognostic models on inpatient pneumonia risk factors., Ethics and Dissemination: The study has been reviewed and approved by all local ethics committees of all participating centres. Study results will be disseminated to the scientific community through peer-reviewed journals and conference presentations, to the SCI community, other stakeholders and via social media, newsletters and engagement activities., Trial Registration Details: ClinicalTrials.gov NCT02891096., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

- Abstract
Despite efforts to improve access to palliative care services, a significant number of patients still have unmet needs throughout their continuum of care. As such, this project was conducted to increase recognition of patients who could benefit from palliative care, increase referrals, and connect regional sites. This study utilized Plan-Do-Study-Act cycles through a quality improvement approach to develop and test the Palliative Care Screening Tool and aimed to screen 100% of patients within 24 hours who were admitted to selected units by February 2017. The intervention was implemented in 3 different units, each within community hospitals. Patients 18 years or older were screened if they were admitted to one of the selected units for the project, regardless of their diagnosis, age, or comorbidities. The percentage of newly admitted patients who were screened and the total number of palliative care consults were assessed as outcome measures. The tool was met with varying compliance among the 3 sites. However, there was an overall increase in consults across all hospital sites, and an increase in the proportion of noncancer patients was demonstrated. Although the aim was not reached, the tool helped to create a shift in the demographic of patients identified as palliative.

- Abstract
Tumor-associated macrophages (TAMs) are the key effector cells in the tumor microenvironment and induce neoangiogenesis, matrix remodeling, and metastasis while suppressing the tumor immune system. These protumoral macrophages display an M2 phenotype induced by IL-4 and IL-13 cytokines. In this study, we hypothesized that the inhibition of the signal transducer and activator of transcription 6 (Stat6) pathway, a common downstream signaling pathway of IL-4 and IL-13, may be an interesting strategy by which to inhibit TAM differentiation and, thus, their protumorigenic activities. In vitro inhibition of the Stat6 pathway by using small interfering RNA or the pharmacologic inhibitor, AS1517499, inhibited the differentiation of mouse RAW264.7 macrophages into the M2 phenotype, as demonstrated by the reduction of Arg-1 (arginase-1) and Mrc-1 (mannose receptor 1) expression and arginase activity. In vivo, AS1517499 significantly attenuated tumor growth and early liver metastasis in an orthotopic 4T1 mammary carcinoma mouse model. Furthermore, in another experiment, we observed an increase in the intrahepatic mRNA expression of F4/80 (EGF-like module-containing mucin-like hormone receptor-like 1; total macrophages) and M2 macrophage markers [ Ym-1 (chitinase 3-like protein 3) and Mrc-1] and metastatic niche markers [ Mmp-2 (matrix metalloproteinase-2), Postn (periostin), and Cd34] in mice with increasing growth of primary tumors. Of interest, these markers were found to be reduced after treatment with AS1517499. In summary, inhibition of the Stat6 pathway in TAMs is a vital therapeutic approach to attenuate tumor growth and metastasis by inhibiting TAM-induced protumorigenic and prometastatic activities.-Binnemars-Postma, K., Bansal, R., Storm, G., Prakash, J.

- Abstract
In recent years, the influence of the tumor microenvironment (TME) on cancer progression has been better understood. Macrophages, one of the most important cell types in the TME, exist in different subtypes, each of which has a different function. While classically activated M1 macrophages are involved in inflammatory and malignant processes, activated M2 macrophages are more involved in the wound-healing processes occurring in tumors. Tumor-associated macrophages (TAM) display M2 macrophage characteristics and support tumor growth and metastasis by matrix remodeling, neo-angiogenesis, and suppressing local immunity. Due to their detrimental role in tumor growth and metastasis, selective targeting of TAM for the treatment of cancer may prove to be beneficial in the treatment of cancer. Due to the plastic nature of macrophages, their activities may be altered to inhibit tumor growth. In this review, we will discuss the therapeutic options for the modulation and targeting of TAM. Different therapeutic strategies to deplete, inhibit recruitment of, or re-educate TAM will be discussed. Current strategies for the targeting of TAM using nanomedicine are reviewed. Passive targeting using different nanoparticle systems is described. Since TAM display a number of upregulated surface proteins compared to non-TAM, specific targeting using targeting ligands coupled to nanoparticles is discussed in detail.

- Abstract
Background: People with spinal cord injury (SCI) may benefit from resistive inspiratory muscle training (RIMT). Current evidence is weak, and little is known about the effect on functional outcomes and long-term effects., Objective: The purpose of this study was to assess immediate and long-term effects of RIMT in people with SCI., Design: This was a single-blinded randomized controlled trial., Setting: The study was conducted at 4 specialized SCI units in the Netherlands., Patients: The study participants were 40 people with SCI (15 with motor complete tetraplegia, 16 with incomplete tetraplegia, 8 with motor complete paraplegia, and 1 with incomplete paraplegia) who had impaired pulmonary function and were admitted for initial inpatient rehabilitation., Intervention: Study participants were randomized to an RIMT group or a control group. All participants received usual rehabilitation care. In addition, participants in the intervention group performed RIMT with a threshold trainer., Measurements: Measurements were performed at baseline, after 8 weeks of intervention, 8 weeks later, and 1 year after discharge from inpatient rehabilitation. Primary outcome measures were: respiratory muscle function, lung volumes and flows, and perceived respiratory function. Secondary outcome measures concerned patient functioning, which included health-related quality of life, limitations in daily life due to respiratory problems, and respiratory complications., Results: During the intervention period, maximum inspiratory pressure (MIP) improved more in the RIMT group than in the control group (11.7 cm H2O, 95% confidence interval=4.3 to 19.0). At follow-up, this effect was no longer significant. No effect on other primary or secondary outcome measures was found except for an immediate effect on mental health., Limitations: The sample size was insufficient to study effects on respiratory complications., Conclusions: Resistive inspiratory muscle training has a positive short-term effect on inspiratory muscle function in people with SCI who have impaired pulmonary function during inpatient rehabilitation., (© 2014 American Physical Therapy Association.)

- Abstract
Objective: To describe changes in pulmonary function (PF) during the 5 years after inpatient rehabilitation in persons with spinal cord injury (SCI) and to study potential determinants of change., Design: Prospective cohort study., Setting: Eight rehabilitation centers with specialized SCI units., Participants: Persons with SCI (N=180)., Interventions: Not applicable., Main Outcome Measures: PF was determined by forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) as a percentage of the predicted value, at the start of rehabilitation, at discharge, and 1 and 5 years after discharge from inpatient rehabilitation. The population was divided into 3 subgroups on the basis of whether their PF declined, stabilized, or improved., Results: FVC improved on average 5.1% over the whole period between discharge of inpatient rehabilitation and 5 years thereafter, but changes differed largely between persons. FVC declined in 14.9% of the population during the first year after discharge. During this year, body mass index, inspiratory muscle strength, change in peak power output, and change in peak oxygen uptake differed significantly between subgroups. FVC declined in 28.3% of the population during the following 4 years, but no differences were found between the subgroups for this period. Subgroups based on changes in FEV1 differed only with respect to change in peak oxygen uptake the first year after discharge., Conclusions: In our study, many persons with SCI showed a decline in PF, larger than the normal age-related decline, during the 5 years after inpatient rehabilitation. Results suggest that a decline in PF during the first year after inpatient rehabilitation is associated with higher body mass index, lower inspiratory muscle strength, and declined physical fitness., (Copyright © 2013 American Congress of Rehabilitation Medicine.

- Abstract
Background: Research reports have described the contents of therapy in spinal cord injury (SCI) rehabilitation only as the total number of therapy hours. We developed the Spinal Cord Injury-Interventions Classification System (SCI-ICS) as a tool to classify therapy to improve mobility and self-care into 3 levels (body functions, basic activities, and complex activities) and 25 categories., Objective: The purposes of this study were: (1) to compare specific contents and amount of therapy provided, with the aim of improving mobility and self-care for people with SCI in Australia, Norway, and the Netherlands and (2) to evaluate the use of the SCI-ICS outside the Netherlands., Design: This was a prospective, descriptive study., Methods: Physical therapists, occupational therapists, and sports therapists in 6 centers recorded all therapy provided to all people with a recent SCI in inpatient rehabilitation during 4 designated weeks. Each treatment session was classified using 1 or more SCI-ICS codes. Duration of each intervention was specified., Results: Seventy-three therapists recorded 2,526 treatments of 79 people with SCI (Netherlands, 48; Australia, 20; Norway, 11). Most therapy time was spent on exercises (overall mean=84%) and on categories at body function and basic activity level of the SCI-ICS. Therapy time significantly differed among countries for 13 of 25 categories. Mean time in minutes per treatment (Netherlands, 28; Australia, 43; Norway, 39) and in hours per patient per week (Netherlands, 4.3; Australia, 5.8; Norway, 6.2) differed significantly., Limitations: The short period and small number of patients may have influenced the results., Conclusions: Therapy in inpatient SCI rehabilitation in all 3 countries focused on mobility and self-care exercises at body function and basic activity level, but differences were present in focus on the various categories and therapy time. The SCI-ICS can be used reliably to describe therapy in different countries.

- Abstract
Purpose: To describe the contents of interventions to improve self-care and mobility for patients with spinal cord injury (SCI) in early post-acute rehabilitation, using the Spinal Cord Injury-Interventions Classification System (SCI-ICS), and to compare these interventions between rehabilitation centres. The SCI-ICS describes therapy to improve self-care and mobility at three levels of functioning and consists of 25 categories with a total of 139 different interventions., Methods: Fifty-three physical therapists, occupational therapists and sports therapists of three Dutch SCI rehabilitation centres recorded interventions with the SCI-ICS for patients with SCI in early post-acute rehabilitation for four consecutive weeks., Results: Therapists recorded 1640 treatment sessions of 48 patients with a SCI. The mean number of treatment sessions per patient per week (8.9 overall) differed between centres (p < 0.05), unlike the mean therapy time in minutes per patient per week (259 overall). Highest frequencies for individual categories were found for 'Muscle Power', 'Walking', and 'Hand rim wheelchair propulsion'., Conclusions: We described the specific contents of therapy of patients with a SCI in three Dutch rehabilitation centres. The largest proportion of time was spent on interventions to improve muscle power, walking, and hand rim wheelchair propulsion.
