Low back pain is a common condition and one of the leading reasons for years of chronic disability. Rehabilitation has been shown to be effective on low back pain, because it is based on the complex and multifactorial mechanisms that low back pain entails.

The aim of this study was to describe and interpret rehabilitation team members' experiences and perspectives regarding an integrated rehabilitation program for patients with chronic low back pain.

This qualitative study used the Interpretive Description methodology. Data consisted of participant observation of 28 rehabilitation team members and four semi-structured focus group interviews with 20 of the 28 participants. The COREQ checklist was used to consolidate the findings in the study.

The results represented an insight into rehabilitation team members' experiences and perspectives regarding the implementation of an integrated rehabilitation program for patients with chronic low back pain. The significance of the rehabilitation team members' expimportant elements when implementing a new rehabilitation intervention in clinical practice and emphasizes the importance of expectations among rehabilitation team members in the implementation process. There should be a specific focus on the importance of involving rehabilitation team members when new interventions are to be implemented, as participation contributes to increased positivity in relation to new initiatives.
The modified Rodnan skin score (mRSS) is often used as a primary outcome measure in systemic sclerosis (SSc) randomized clinical trials (RCTs). Previous cohort studies with predominantly European Caucasian patients showed that setting an upper limit of mRSS as a selection criterion for RCTs leads effectively to enrichment with progressive patients. This study aimed to demonstrate this effect in an ethnically diverse cohort, rich in patients positive for anti-RNA polymerase III antibodies (Pol3).

We selected from the Genetics versus Environment in Scleroderma Outcomes Study (GENISOS) cohort patients with diffuse cutaneous SSc (dcSSc), who had mRSS of 7 or more at inclusion and a documented mRSS after 12 ± 2 months. Progression of skin fibrosis was defined as an increase in mRSS greater than 5 points and 25% or more from baseline. To identify the optimal cutoff for the baseline mRSS yielding the highest sensitivity for progressive skin fibrosis, we developed ROC curves and logistic regression models with "progressors.Skeletal muscle dysfunction in survivors of pneumonia disproportionately affects older individuals in whom it causes substantial morbidity. We found that skeletal muscle recovery was impaired in old compared with young mice after influenza A virus-induced pneumonia. In young mice, recovery of muscle loss was associated with expansion of tissue-resident skeletal muscle macrophages and downregulation of MHC II expression, followed by a proliferation of muscle satellite cells. These findings were absent in old mice and in mice deficient in Cx3cr1. Transcriptomic profiling of tissue-resident skeletal muscle macrophages from old compared with young mice showed downregulation of pathways associated with phagocytosis and proteostasis, and persistent upregulation of inflammatory pathways. Consistently, skeletal muscle macrophages from old mice failed to downregulate MHCII expression during recovery from influenza A virus-induced pneumonia and showed impaired phagocytic function in vitro. Like old animals, mice deficient in the phagocytic receptor Mertk showed no macrophage expansion, MHCII downregulation, or satellite cell proliferation and failed to recover skeletal muscle function after influenza A pneumonia. Our data suggest that a loss of phagocytic function in a CX3CR1+ tissue-resident skeletal muscle macrophage population in old mice precludes satellite cell proliferation and recovery of skeletal muscle function after influenza A pneumonia.Diabetic foot ulcers are a major health care concern with limited effective therapies. Mesenchymal stem cell (MSC)-based therapies are promising treatment options due to their beneficial effects of immunomodulation, angiogenesis, and other paracrine effects. We investigated whether a bioengineered scaffold device containing hypoxia-preconditioned, allogeneic human MSCs combined with the beta-adrenergic antagonist timolol could improve impaired wound healing in diabetic mice. Different iterations were tested to optimize the primary wound outcome, which was percent of wound epithelialization. Takinib in vitro MSC preconditioned in 1 μM timolol at 1% oxygen (hypoxia) seeded at a density of 2.5 × 105  cells/cm2 on Integra Matrix Wound Scaffold (MSC/T/H/S) applied to wounds and combined with daily topical timolol applications at 2.9 mM resulted in optimal wound epithelialization 65.6% (24.9% ± 13.0% with MSC/T/H/S vs 41.2% ± 20.1%, in control). Systemic absorption of timolol was below the HPLC limit of quantification, suggesting that with the 7-day treatment, accumulative steady-state timolol concentration is minimal. In the early inflammation stage of healing, the MSC/T/H/S treatment increased CCL2 expression, lowered the pro-inflammatory cytokines IL-1B and IL6 levels, decreased neutrophils by 44.8%, and shifted the macrophage ratio of M2/M1 to 1.9 in the wound, demonstrating an anti-inflammatory benefit. Importantly, expression of the endothelial marker CD31 was increased by 2.5-fold with this treatment. Overall, the combination device successfully improved wound healing and reduced the wound inflammatory response in the diabetic mouse model, suggesting that it could be translated to a therapy for patients with diabetic chronic wounds.
Our purpose was to determine the complication rate from intravascular ultrasound (IVUS) in a large, multicenter cohort of pediatric heart transplant (PHT) patients.

We retrospectively reviewed all PHT who underwent IVUS at 5 institutions (2006-2014). Rates of major and minor complications were calculated. All adverse events (AE) were graded from 1 to 5 using a previously published AE severity scale.

There were 1380 catheterizations in 505 patients and 32 AE (2.3%); 9 major (0.6%) and 23 AE (1.7%). The major AE attributed to IVUS were all coronary artery vasospasm (7). Major and minor AE rates directly related to IVUS were 0.5% and 0.7%, respectively. Minor AE possibly attributable to IVUS included excessive fluoroscopy (3) and transient ST segment changes (7). Of AE related to IVUS, only 3 were of moderate severity. The rest were≤minor in severity. There were no reports of coronary artery dissection or death.

Most AE during routine PHT coronary evaluation with IVUS were minor and not directly related to the use of IVUS.
