RESUMEN
BACKGROUND: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has been a continuing source of hospital-acquired infection and outbreaks. At Akershus University Hospital in Norway, traditional contact tracing has been combined with whole-genome sequencing (WGS) surveillance in real-time to investigate potential hospital outbreaks. AIM: To describe the advantages and challenges encountered when using WGS as a real-time tool in hospital outbreak investigation and surveillance during the SARS-CoV-2 pandemic. METHODS: Routine contact tracing in the hospital was performed for all healthcare workers (HCWs) who tested positive for SARS-CoV-2. Viral RNA from all positive patient and HCW samples was sequenced in real-time using nanopore sequencing and the ARTIC Network protocol. Suspected outbreaks involving five or more individuals with viral sequences were described. FINDINGS: Nine outbreaks were suspected based on contact tracing, and one outbreak was suspected based on WGS results. Five outbreaks were confirmed; of these, two outbreaks were supported but could not be confirmed by WGS with high confidence, one outbreak was found to consist of two different lineages, and two outbreaks were refuted. CONCLUSIONS: WGS is a valuable tool in hospital outbreak investigations when combined with traditional contact tracing. Inclusion of WGS data improved outbreak demarcation, identified unknown transmission chains, and highlighted weaknesses in existing infection control measures.

INTRODUCTION: There is a wide spectrum of noninfectious gastrointestinal pathology, causing considerable morbidity and mortality in CVID, where both etiology and effective therapy are under debate. AREAS COVERED: This review will focus on the noninfectious inflammation in the GI tract in CVID patients, covering the both the upper and lower GI tract inflammation, including the liver. The controversy of the CVID enteropathy definition and that of gluten-free diet for celiac-like disease in CVID will be discussed. Furthermore, the review will cover the link between GI inflammation and GI cancer. Finally, the role of gut microbiota, IgA, and genetics and its relationship with CVID enteropathy is scrutinized. The authors reviewed literature from PubMed. EXPERT OPINION: The heterogeneity and the unknown mechanism behind CVID enteropathy, and thereby the lack of effective treatment, is one of the key challenges in the field of CVID. Celiac-like disease in CVID is due to immune dysregulation, and a gluten-free diet is therefore not indicated. Gut microbial dysbiosis and mucosal IgA can initiate systemic and local inflammation and is involved in the immune dysregulation in CVID. Considering the heterogeneity of CVID enteropathy, personalized medicine is probably the future for these patients.

In recent years, hyperpolarized 13C magnetic resonance spectroscopic (MRS) imaging has emerged as a complementary metabolic imaging approach. Hyperpolarization via dissolution dynamic nuclear polarization is a technique that enhances the MR signal of 13C-enriched molecules by a factor of > 104, enabling detection downstream metabolites in a variety of intracellular metabolic pathways. The aim of the present review is to provide the reader with an update on hyperpolarized 13C MRS imaging and to assess the future clinical potential of the technology. Several carbon-based probes have been used in hyperpolarized studies. However, the first and most widely used 13C-probe in clinical studies is [1-13C]pyruvate. In this probe, the enrichment of 13C is performed at the first carbon position as the only modification. Hyperpolarized [1-13C]pyruvate MRS imaging can detect intracellular production of [1-13C]lactate and 13C-bicarbonate non-invasively and in real time without the use of ionizing radiation. Thus, by probing the balance between oxidative and glycolytic metabolism, hyperpolarized [1-13C]pyruvate MRS imaging can image the Warburg effect in malignant tumors and detect the hallmarks of ischemia or viability in the myocardium. An increasing number of clinical studies have demonstrated that clinical hyperpolarized 13C MRS imaging is not only possible, but also it provides metabolic information that was previously inaccessible by non-invasive techniques. Although the technology is still in its infancy and several technical improvements are warranted, it is of paramount importance that nuclear medicine physicians gain knowledge of the possibilities and pitfalls of the technique. Hyperpolarized 13C MRS imaging may become an integrated feature in combined metabolic imaging of the future.

BACKGROUND: During the SARS-CoV-2 pandemic, healthcare workers (HCWs) are being exposed to infection both at work and in their communities. Determining where HCWs might have been infected is challenging based on epidemiological data alone. At Akershus University Hospital, Norway, several clusters of possible intra-hospital SARS-CoV-2 transmission were identified based on routine contact tracing. AIM: To determine whether clusters of suspected intra-hospital SARS-CoV-2 transmission could be resolved by combining whole genome sequencing (WGS) of SARS-CoV-2 with contact tracing data. METHODS: Epidemiological data were collected during routine contact tracing of polymerase chain reaction-confirmed SARS-CoV-2-positive HCWs. Possible outbreaks were identified as wards with two or more infected HCWs defined as close contacts who tested positive for SARS-CoV-2 less than three weeks apart. Viral RNA from naso-/oropharyngeal samples underwent nanopore sequencing in direct compliance to the ARTIC Network protocol. FINDINGS: Five outbreaks were suspected from contact tracing. Viral consensus sequences from 24 HCWs, two patients, and seven anonymous samples were analysed. Two outbreaks were confirmed, one refuted, and two remained undetermined. One new potential outbreak was discovered. CONCLUSION: Combined with epidemiological data, nanopore WGS was a useful tool for investigating intra-hospital SARS-CoV-2 transmission. WGS helped to resolve questions about possible outbreaks and to guide local infection prevention and control measures.

Osteopontin (OPN) is a multifunctional protein highly expressed in milk, where it is hypothesized to be involved in immunological signaling via the conserved Arg-Gly-Asp (RGD) integrin-binding sequence. Intervention studies have indicated beneficial effects of orally administered OPN in animal and human infants, but the mechanisms underlying these effects are not well described. To induce physiological effects, OPN must resist gastrointestinal transit in a bioactive form. In this study, we subjected bovine milk OPN to in vitro gastrointestinal transit, and characterized the generated fragments using monoclonal antibody and mass spectrometric analyses. We found that the fragment Trp27-Phe151 containing the integrin-binding RGD sequence resisted in vitro gastric digestion. This resistance was dependent on glycosylation of threonine residues near the integrin-binding sequence in both human and bovine milk OPN. Furthermore, the fragment Trp27-Phe151 retained the ability to interact with integrins in an RGD-dependent process. These results suggest a mechanism for how ingested milk OPN can induce physiological effects via integrin signaling in the intestine.

The objective of this study was to determine if real-world ceftaroline treatment in adults hospitalized for acute bacterial skin and skin structure infections (ABSSSI) is associated with decreased infection-related length of stay (LOSinf) compared to that with vancomycin. This was a retrospective, multicenter, cohort study from 2012 to 2017. Cox proportional hazard regression, propensity score matching, and inverse probability of treatment weighting (IPTW) were used to determine the independent effect of treatment group on LOSinf The patients were adults hospitalized with ABSSSI and treated with ceftaroline or vancomycin for ≥72 h within 120 h of diagnosis at four academic medical centers and two community hospitals in Arizona, Florida, Michigan, and West Virginia. A total of 724 patients were included (325 ceftaroline treated and 399 vancomycin treated). In general, ceftaroline-treated patients had characteristics consistent with a higher risk of poor outcomes. The unadjusted median LOSinf values were 5 (interquartile range [IQR], 3 to 7) days and 6 (IQR, 4 to 8) days in the vancomycin and ceftaroline groups, respectively (hazard ratio [HR], 0.866; 95% confidence interval [CI], 0.747 to 1.002). The Cox proportional hazard model (adjusted HR [aHR], 0.891; 95% CI, 0.748 to 1.060), propensity score-matched (aHR, 0.955; 95% CI, 0.786 to 1.159), and IPTW (aHR, 0.918; 95% CI, 0.793 to 1.063) analyses demonstrated no significant difference in LOSinf between groups. Patients treated with ceftaroline were significantly more likely to meet criteria for discharge readiness at day 3 in unadjusted and adjusted analyses. Although discharge readiness at day 3 was higher in ceftaroline-treated patients, LOSinf values were similar between treatment groups. Clinical and nonclinical factors were associated with LOSinf.

PURPOSE: The most effective treatment for longstanding groin pain with no hernia present has not been designated. The aim of this systematic review was to assess whether surgical or conservative treatment are the most effective in reducing pain and thereby returning patients to habitual activity. METHODS: PubMed, Embase, and Cochrane were searched. We included adults diagnosed with longstanding groin pain with no hernia. Treatment included inguinal hernia repair, tenotomy, and nonsurgical management. Outcomes included return to habitual activity, pain, patient satisfaction, re-operations for the operated patients, and shift to surgery for the non-operated patients. We included randomized controlled trials and observational studies with more than 10 participants. RESULTS: In total, 72 studies with 3629 patients were included. Only five studies used a comparison group. After inguinal hernia repair, 94% returned to habitual activity after median 10 weeks, 92% became pain free, and 92% were satisfied with their treatment. After adductor tenotomy, 90% returned to habitual activity after median 12 weeks, 90% became pain free, and 84% were satisfied. After combined inguinal hernia repair and adductor tenotomy, 97% returned to habitual activity after median 10 weeks, 92% became pain free, and 91% were satisfied with their treatment. After nonsurgical management, 80% returned to habitual activity after median 12 weeks, 67% became pain free, 56% were satisfied, and 21% shifted to surgery. CONCLUSION: We found that surgery seems to be more efficient in return the patients to habitual activity, reduce their pain, and satisfy them than conservative treatment.

OBJECTIVE: To assess early recovery of physical health after robotic minimally invasive surgery (RMIS) for early-stage endometrial cancer using the European Organisation of Research and Treatment of Cancer Computer Adaptive Test Core questionnaire (EORTC CAT Core). The EORTC CAT Core provides individualised measurements while maintaining comparability. A hypothesis of individual complete recovery to baseline within three post-surgical weeks was evaluated. METHODS: Ninety-four women who underwent RMIS for early-stage endometrial cancer were included consecutively. The EORTC CAT Core was distributed before surgery and prospectively every week during the first post-operative month. Repeated measures models were fitted for each of the four domains (physical functioning, role function, fatigue, and pain) and tested for impact of age, ASA score, minor/major surgery, and the individual baseline scores (poorest, intermediate, best). RESULTS: Women with the lowest physical functioning, lowest role function, highest fatigue level, and highest pain level at baseline all recovered within three weeks. Women with the highest physical functioning, highest role function, lowest level of fatigue, and lowest level of pain at baseline did not reach their individual baselines within the first post-operative month but had the most favourable domain-scores three weeks post-operatively. CONCLUSION: The individual woman's physical health baseline score is predictive for her postoperative recovery following RMIS for early-stage endometrial cancer. Women with the best physical health had the best postoperative functions and lowest level of symptoms; however their recovery to baseline was prolonged. Computer adaptive testing may be a valuable tool for individualised pre-operative information and supportive care during surveillance.

Common variable immunodeficiency (CVID) patients have reduced gut microbial diversity compared to healthy controls. The reduced diversity is associated with gut leakage, increased systemic inflammation and ten "key" bacteria that capture the gut dysbiosis (dysbiosis index) in CVID. Rifaximin is a broad-spectrum non-absorbable antibiotic known to reduce gut leakage (lipopolysaccharides, LPS) in liver disease. In this study, we explored as a 'proof of concept' that altering gut microbial composition could reduce systemic inflammation, using CVID as a disease model. Forty adult CVID patients were randomized, (1:1) to twice-daily oral rifaximin 550 mg versus no treatment for 2 weeks in an open-label, single-centre study. Primary endpoints were reduction in plasma/serum levels of soluble (s) CD14, sCD25, sCD163, neopterin, CRP, TNF, LPS and selected cytokines measured at 0, 2 and 8 weeks. Secondary endpoint was changes in intra-individual bacterial diversity in stool samples. Rifaximin-use did not significantly change any of the inflammation or gut leakage markers, but decreased gut microbial diversity compared with no treatment (p = 0.002). Importantly, the gut bacteria in the CVID dysbiosis index were not changed by rifaximin. The results suggest that modulating gut microbiota by rifaximin is not the chosen intervention to affect systemic inflammation, at least not in CVID.

The recovery of oxygen uptake to the standard metabolic rate (SMR) following exhaustive chasing exercise in Atlantic salmon Salmo salar parr occurred in three phases (rapid, plateau and slow). The initial recovery phase lasted 0·7 h and contributed 16% to the total excess post-exercise oxygen consumption (EPOC). It was followed by a longer plateau phase that contributed 53% to the total EPOC. The slow recovery phase that completed recovery of SMR, which has not been reported previously, made a 31% contribution to the total EPOC. The plasticity of EPOC was demonstrated in exercise-trained fish. Exercise training increased EPOC by 39% when compared with control fish (mean ± S.E., 877·7 ± 73·1 v. 629·2 ± 53·4 mg O2 kg-1 , d.f. = 9, P < 0·05), with the duration of the plateau phase increasing by 38% (4·7 ± 0·58 v. 3·4 ± 0·16 h, d.f. = 9, P < 0·05) and the contribution of the slow phase to the total EPOC increasing by 80% (173·9 ± 23·9 v. 312·5 ± 50·4 mg O2 kg-1 , d.f. = 9, P < 0·05). As a result, the combination of the plateau and slow phases of exercise-trained fish increased by 47% compared with control fish (756·6 ± 71·4 v. 513·6 ± 43·1 mg O2 kg-1 ; d.f. = 9, P = 0·01). To substantiate the hypothesis that the plateau and slow recovery phase of EPOC was related to general metabolic recovery following exhaustive exercise, the time-course for recovery of SMR was compared with previously published metabolite recovery profiles. The final phase of metabolic recovery was temporally associated with the final phases of gluconeogenesis, lactate oxidation and muscle intracellular pH regulation. Therefore, the plasticity of the latter phase of EPOC agreed with the known effects of exercise training in fishes.

Influenza virus infection causes worldwide seasonal epidemics. Although influenza is usually a mild disease, a minority of patients experience very severe fulminating disease courses. Previous studies have demonstrated a role for type I interferon (IFN) in anti-viral responses during influenza. So far, however, IFN regulatory factor (IRF)7 deficiency is the only genetic cause of severe influenza described in humans. In this study we present a patient with severe influenza A virus (IAV) H1N1 infection during the 2009 swine flu pandemic. By whole exome sequencing we identified two variants, p.R71H and p.P885S, located in the caspase activation and recruitment domain (CARD) and RNA binding domains, respectively, of DExD/H-box helicase 58 (DDX58) encoding the RNA sensor retinoic acid inducible gene 1 (RIG-I). These variants significantly impair the signalling activity of RIG-I. Similarly, patient cells demonstrate decreased antiviral responses to RIG-I ligands as well as increased proinflammatory responses to IAV, suggesting dysregulation of the innate immune response with increased immunopathology. We suggest that these RIG-I variants may have contributed to severe influenza in this patient and advocate that RIG-I variants should be sought in future studies of genetic factors influencing single-stranded RNA virus infections.

BACKGROUND: Excessive amounts of bile acids entering the colon due to bile acid malabsorption cause chronic bile acid diarrhoea. Diagnosis is possible by measuring the retention fraction of orally ingested 75 Selenium homotaurocholic acid (SeHCAT). The knowledge of long-term effects of medical treatment is sparse. AIM: To describe diarrhoea, adherence to treatment, treatment effects and quality of life in a large, well-defined cohort of patients with bile acid diarrhoea. METHODS: A retrospective survey was performed among 594 patients with bile acid malabsorption verified by SeHCAT scans at our unit between 2003 and 2016. Questionnaires about medical history, diarrhoea, use of medication, and quality of life scores were mailed to all patients. RESULTS: Among 594 patients 377 (69%) responded. Among respondents, 121 (32%) had bile acid diarrhoea due to ileal disease or resection (type 1), 198 (52%) idiopathic bile acid diarrhoea (type 2) and 58 (16%) bile acid diarrhoea due to other non-ileal disease, mainly cholecystectomy (type 3). At follow-up, half of the patients, 184 (50%), reported improvement of diarrhoea. However, 273 patients (74%) still reported diarrhoea and 234 (62%) regularly used anti-diarrhoeal medication. In spite of treatment, 235 (64%) considered reduced quality of life by diarrhoea and 184 (50%) reported that diarrhoea was unaltered or worse than before established diagnosis. CONCLUSION: Many patients with bile acid diarrhoea continue to have bothersome diarrhoea in spite of correct diagnosis and treatment.

BACKGROUND: Maintaining disease remission throughout pregnancy in women with inflammatory bowel disease is of the utmost importance to decrease the risk of adverse outcome. In general, corticosteroids are safe to use during pregnancy, but no data exist in the specific use of budesonide MMX. We report four cases of budesonide MMX in pregnancy and pregnancy outcome. METHODS: Four women with inflammatory bowel disease experienced disease activity during pregnancy. They were treated with budesonide MMX in an attempt to obtain clinical remission. Disease activity was assessed through physician's global assessment as well as lower endoscopy. RESULTS: Budesonide MMX proved effective in achieving remission in three out of four women. One woman had an uncomplicated colectomy in the second trimester. All children were born normal for gestational age, with no congenital abnormalities and have reached all their developmental milestones. The four children have received vaccines according to the national immunization program without complications. CONCLUSION: No adverse pregnancy outcomes were reported after the use of budesonide MMX. To our knowledge, this is the first report on the safety of budesonide MMX treatment in pregnant women with inflammatory bowel disease.

OBJECTIVES: Staphylococcus aureus colonization leading to skin and soft-tissue infections (SSTI) are known challenges in crowded settings such as the military. The aim of the study was to establish and compare the prevalence of S. aureus colonization in recruits at enrolment and discharge after the first year of military service, and to investigate the prevalence of S. aureus SSTI. METHODS: All recruits entering first year of military service in January 2013 to be stationed at three garrisons in the northern part of Norway were invited to join this prospective cohort study. Swabs were taken from nose, throat and perineum. Staphylococcus aureus was identified using standard culturing methods. Methicillin resistance was determined by a cefoxitin disc diffusion test. RESULTS: Of the 923 eligible recruits, 512 were included at enrolment; 265/512 (52%) were also screened at discharge. Staphylococcus aureus colonization was high, and increased significantly during military service (166/265 versus 224/265, p < 0.001) mainly caused by increase in throat colonization alone or in combination with nasal colonization. All S. aureus isolates were susceptible to methicillin. SSTI was self-reported in 7/265 (3%) recruits, of which only one was confirmed by a military physician. CONCLUSION: Staphylococcus aureus colonization increased during military service, but there were few confirmed reports of SSTI. Inclusion of throat swab provides important information as â¼20% of the recruits were only positive in their throat. Further analyses need to be performed to investigate if the increase in colonization is caused by specific S. aureus stains.

Monitoring racehorse fatality and associated jockey falls provides benchmarks for intervention strategies. The aims of this study were to describe the incidence of and reasons for fatalities in Thoroughbred horses during flat races in the Australian Capital Territory and New South Wales (NSW), Australia, and to describe reported jockey falls and injuries associated with racehorse fatalities. A cohort study identified all racehorse fatalities reported through Racing NSW for the 2009-2010 to 2013-2014 racing seasons. Risks of racehorse fatality, fatal musculoskeletal injury, spontaneous death (as distinct from euthanasia) and racehorse fatality associated jockey falls and injuries were calculated using Poisson regression. A total of 167 horse fatalities were reported, with an overall incidence of 0.59 deaths/1000 starts. Forty-nine reasons for horse fatality were reported, although post-mortem examinations were conducted on only 52/165 (31.5%) horses. Musculoskeletal injury accounted for 144/167 (86.2%) fatalities, with an incidence of 0.52/1000 starts. Fractures comprised 96/167 (57.5%) fatalities, with the fetlock or proximal sesamoid bones being the most common fracture location, comprising 36/96 (37.5%) fractures. Only 22/166 (13.3%) racehorse fatalities were due to spontaneous death, representing an incidence of 0.08/1000 starts. A total of 50 racehorse fatality associated jockey falls were reported (incidence of 0.18/1000 starts), with 32 reported jockey injuries (incidence of 0.12/1000 starts). Most racehorse fatality associated jockey injuries occurred to the limbs (17/32, 53.1%), particularly the upper limb. The estimates for both horse fatality and associated jockey injury were comparable with previous estimates from other jurisdictions internationally.

Patients presenting to the emergency department (ED) represent a heterogeneous population comprised of all ages, various backgrounds, such as from the community and skilled-nursing facilities (SNFs), and at various risks for resistant pathogens. The aim of this study was to compare patient group-specific urinary antibiograms in the ED. Adults presented to the ED with an ICD 9/10 code urinary tract infection (UTI) diagnosis during July 2015 to June 2016 were randomly selected (n = 500) to extract relevant demographic, laboratory, and clinical data from the medical record. Urinary Escherichia coli antibiograms were compared between institutional versus ED and among ED patients (male versus female; age of 18 to 64 years versus ≥65 years; female aged 18 to 50 years versus >50 years; home versus SNF; and admitted versus discharged). E. coli grew from 56% (145/259) of the positive urine cultures. Overall ciprofloxacin (CIP), trimethoprim-sulfamethoxazole (SXT), and cefazolin (CFZ) susceptibilities were <71%. Differences in antibiograms were the following: lower CFZ and SXT susceptibilities in ED versus institutional (CFZ, 67% versus 86% [P = 0.001]; SXT, 66% versus 74% [P = 0.02]), lower ampicillin and gentamicin susceptibilities in females aged 18 to 50 years versus >50 years (32% versus 52% [P = 0.04]; 78% versus 93% [P = 0.02]), lower CIP susceptibilities in the elderly (64% versus 81%; P = 0.03), SNF versus home (35% versus 77%; P < 0.001), admitted versus discharged (63% versus 78%; P = 0.04), and lower SXT susceptibilities in patients aged <65 years versus the elderly (58% versus 71%; P = 0.01). Nitrofurantoin showed >80% susceptibility in all groups. Patient group-specific urinary antibiograms revealed distinct differences in E. coli susceptibility and should be developed to better inform empirical UTI therapy selection in the ED.

A multidrug-resistant, methicillin-resistant Staphylococcus aureus (MRSA) clone, PVL-positive ST772-MRSA-V, named the Bengal Bay clone, is emerging worldwide. In Norway, where MRSA prevalence is low, a sudden increase in ST772-MRSA-V initiated a nationwide molecular epidemiological study. Clinical data were obtained from the Norwegian Surveillance System for Communicable Diseases (MSIS). S. aureus isolates were characterised by antibiotic susceptibility profiles and comprehensive genotyping (spa typing, MLVA, DNA microarray). ST772-MRSA was detected in 145 individuals during 2004-2014, with 60% of cases occurring in 2013-2014. Median age was 31 years and male/female ratio 1.16. The majority had a family background from the Indian subcontinent (70%). MRSA acquisition was mainly reported as unknown (39%) or abroad (42%), the latter associated with a home-country visit (59%), tourism (16%), and immigration (13%). Clinical infection was present in 75%, predominantly by SSTI (83%), 18% were admitted to hospital and 42% were linked to small-scale outbreaks (n = 25). All isolates were multidrug-resistant. Most isolates were resistant to erythromycin, gentamicin and norfloxacin. Genotyping revealed a conserved clone predominated by spa type t657 (83%), MLVA-type 432 (67%) and the genes lukF/S, sea, sec/sel, egc, scn, cna, ccrAA/ccrC, agrII and cap5. A few untypical ccr gene combinations were detected. Bengal Bay isolates have likely been imported on several occasions and revision of infection control guidelines may prevent further spread.

STUDY DESIGN: Cross-sectional. OBJECTIVES: To describe participation in leisure time physical activity (LTPA) (amount, intensity and type) among older adults with long-term spinal cord injury (SCI), and to investigate the associations with sociodemographics, injury characteristics and secondary health conditions (SHCs). SETTING: Home settings in southern Sweden. METHODS: Data from the Swedish Aging with Spinal Cord Injury Study (SASCIS). The physical activity recall assessment for people with SCI was used to assess LTPA among 84 men and 35 women (mean age 63.5 years, mean time since injury 24 years, injury levels C1-L5, American Spinal Injury Association Impairment Scale A-D). Associations were analyzed statistically using hierarchical multivariable regression. RESULTS: Twenty-nine percent reported no LTPA, whereas 53% performed moderate-to-heavy intensity LTPA. The mean minutes per day of total LTPA was 34.7 (±41.5, median 15, range 0-171.7) and of moderate-to-heavy LTPA 22.5 (±35.1, median 5.0, range 0-140.0). The most frequently performed activities were walking and wheeling. Sociodemographics, injury characteristics and SHCs (bowel-related and bladder-related problems, spasticity and pain) explained 10.6% and 13.4%, respectively, of the variance in total and moderate-to-heavy LTPA. Age and wheelchair use were significantly, negatively associated with total LTPA. Women, wheelchair users and employed participants performed significantly less moderate-to-heavy LTPA than men, those using walking devices/no mobility device and unemployed participants. CONCLUSION: Many older adults with long-term SCI do not reach the amount or intensity of LTPA needed to achieve fitness benefits. Research is needed on how to increase LTPA and to identify modifiable factors that could enhance their participation.
