The area of most significant progress is national PA guidelines. #link# Establishing prevalence targets, streamlining surveillance systems, and investing in public education with supportive policies, environments, and opportunities would strengthen national policy efforts to increase PA and reduce sedentary behavior.
Readmissions for patients with heart failure (HF) continues to be a target of value-based purchasing initiatives. Do-not-resuscitate (DNR) orders-one part of advance care planning (ACP)-have been shown to be related to other patient outcomes but has not been explored as a risk factor for HF readmission.
Examine the association between DNR and 30-day readmissions among elderly patients with HF admitted to hospitals in Pennsylvania.
Data included hospital discharges from 2011 to 2014 of patients 65+ years with a primary diagnosis of HF. Logistic regression was used to model the relationship between DNR and 30-day readmission.
Among 107,806 patients, 20.9% were readmitted within 30 days. After controlling for covariates, patients with HF who had a DNR were less likely to be readmitted to the hospital (OR=0.85, 95% CI 0.80-0.91, p<0.001).
Documentation of a DNR may inform efforts to reduce readmissions among elderly patients with HF.

As the Coronavirus disease 2019 (COVID-19) pandemic accelerates, our hospitals have become overwhelmed.
To describe detection of COVID-19 in asymptomatic hospitalized individuals awaiting advanced therapies for HF and the management of complications of COVID-19.
We present a unique case report of hospital-acquired COVID-19 in a patient on temporary mechanical circulatory support.
Despite intensive care and monitoring, he developed rapid progression of hypoxic respiratory failure which led to his death.
This case highlights various considerations for a patient with temporary MCS. It illustrates the high risk for development of COVID-19 for vulnerable hospitalized patients.

Among Left Ventricular Assist Device (LVAD) implanted patients, body image modifications might occur.
To explore the associations between sexual functioning, confidence in LVAD technology, personal wellbeing, and body image.
The cross-sectional study included 30 conveniently recruited LVAD implanted patients who completed Body Image Scale, sexual functioning, confidence in LVAD technology, and Personal Wellbeing Index questionnaires. The associations between the research variables were examined with multiple regression analyses.
The mean age of the participants was 63 (SD=10), 90% were men. The mean scores were sexual functioning - 2.43 (SD=1.20, range 1-5); confidence in LVAD technology - 2.63 (SD=1.04, range 1-5); Well-Being Index - 6.61 (SD=1.53, range 0-10); and body image - 14.5 (SD=4.17, range 5-20). Sexual functioning (p<.01) and LVAD technology confidence (p=.04) significantly predicted body image.
Healthcare professionals should be aware of challenges regarding body image faced by LVAD implanted patients and to address related factors.

Similar to six-minute walk test (6MWT), sit-to-stand test (STST) is a self-paced test which elicits sub-maximal effort; therefore, it is suggested as an alternative measurement for functional exercise capacity in various pulmonary conditions including COPD and cystic fibrosis. We aimed to investigate the association between 30-second STST (30s-STST) and 6MWT in both children with bronchiectasis (BE) and their healthy counterparts, as well as exploring cardiorespiratory burden and discriminative properties of both tests.
Sixty children (6 to 18-year-old) diagnosed with non-cystic fibrosis BE and 20 age-matched healthy controls were included. Both groups performed 30s-STST and 6MWT. Test results, and heart rate, SpO
and dyspnea responses to tests were recorded.
Univariate analysis revealed that 30s-STST was able to explain 52% of variance in 6MWT (r=0.718, p<0.001) in BE group, whereas 20% of variance in healthy controls (r=0.453, p=0.045). 6MWT elicited higher changes in heart rate and dyspnea level compared to 30s-STST, indicating it was more physically demanding. Both 30s-STST (21.65±5.28vs 26.55±3.56 repetitions) and 6MWT (538±85vs 596±54m) were significantly lower in BE group compared to healthy controls (p<0.01). Receiver operating characteristic (ROC) curve analysis revealed an area under the ROC curve (UAC) of 0.765 for 30s-STST and 0.693 for 6MWT in identifying the individuals with or without BE (p<0.05). Comparison between AUCs of 30s-STST and 6MWT yielded no significant difference (p=0.466), indicating both tests had similar discriminative properties.
30s-STST is found to be a valid alternative measurement for functional exercise capacity in children with BE.

Specifically, it's unclear whether fibrils are structurally continuous along the tendon length and bear load independently, or if they are discontinuous and transfer load through interfibrillar shear forces. To address this question, we investigated whether the multiscale mechanics of rat tail tendon fascicles is dependent on sample gauge length. We hypothesized that as the grip-to-grip length is reduced and approaches the length of the collagen fibrils, tendon fascicles will adopt a multiscale mechanical response consistent with structurally continuous fibrils. Our findings show that, for gauge lengths of 20 mm or greater, the local fibril strains are less than the bulk tissue strains, which can be explained by relative sliding between discontinuous collagen fibrils. In contrast, at a 5 mm gauge length, the fibril strains are equivalent to the applied tissue strains, suggesting that the collagen fibrils are structurally continuous between the grips. Additionally, the macroscale tissue modulus is increased at gauge lengths of 5 and 10 mm. Together, these data support the hypothesis that collagen fibrils in rat tail tendon fascicles are discontinuous and also suggest that their length is between 5 and 10 mm. This fundamental information regarding tendon structure-function relationships underscores the importance of the tissue components that transmit load between fibrils and is critical for understanding tendon pathology as well as establishing structural benchmarks for suitable tissue engineered replacements.Longitudinal in vivo monitoring is essential for the design and evaluation of biomaterials. An ideal method would provide three-dimensional quantitative information, high spatial resolution, deep tissue penetration, and contrast between tissue and material structures. Photoacoustic (PA) or optoacoustic imaging is a hybrid technique that allows three-dimensional imaging with high spatial resolution. In addition, photoacoustic imaging allows for imaging of vascularization based on the intrinsic contrast of hemoglobin. In this study, we investigated photoacoustic computed tomography (PACT) as a tool for longitudinal monitoring of an implanted hydrogel in a small animal model. Hydrogels were loaded with gold nanorods to enhance contrast and imaged weekly for 8 weeks. PACT allowed non-invasive three-dimensional, quantitative imaging of the hydrogels over the entire 8 weeks. Quantitative volume analysis was used to evaluate the in vivo degradation kinetics of the implants which deviated slightly from in vitro predictions. Multispectral imaging allowed for the simultaneous analysis of hydrogel degradation and local vascularization. link2 These results provide support for the substantial potential of PACT as a tool for insight into biomaterial performance in vivo.Development of antitumor agents with high efficiency and low toxicity is one of the most important goals for biomedical research. However, most traditional therapeutic strategies were limited due to their non-specificity and abnormal tumor microenvironments, causing a poor therapeutic efficiency and severe side effects. In this paper, a tumor targeted self-synergistic nanoplatform (designated as PAO@PCN@HA) was developed for chemotherapy sensitized photodynamic therapy (PDT) against hypoxic tumors. The efficient drug loading of phenylarsine oxide (PAO) in porphyrinic metal organic framework of PCN-224 as well as the surface modification of hyaluronic acid (HA) improved the targeted drug delivery and reduced the side effects of PAO at the therapeutic dose. Particularly, PAO as an arsenical-based chemotherapeutic agent could not only induce cell apoptosis by generating reactive oxygen species (ROS), but also regulate tumor microenvironments to improve the PDT effect of PCN-224 by mitigating hypoxia and consuming cellular GSH. Both in vitro and in vivo investigations confirmed an effective self-synergy of PAO@PCN@HA in hypoxic tumor therapy with a low systemic toxicity. This integration of microenvironment adjustment with tumor targeted self-synergistic mechanism might provide a new insight for the development of arsenic-based antitumor strategy for clinical applications.
Medulloblastoma (MB) is a malignant tumor of the central nervous system (CNS), and sarcoidosis is a chronic inflammatory disease of many organ systems, commonly affecting the lungs. No association between MB and sarcoidosis was described in the literature. MB and sarcoidosis have mutual molecular and signaling pathways that may predispose patients with sarcoidosis to develop MB. We describe a patient with sarcoidosis who developed MB.
The patient is a 36-year-old diagnosed with pulmonary sarcoidosis presented with ataxia, bilateral horizontal nystagmus, diplopia, and bilateral upper limb dysmetria was found to have a cerebellar mass on magnetic resonance imaging (MRI). He was initially treated with corticosteroids as a case of neurosarcoidosis. The patient's symptoms worsened, and repeat MRI showed an increase in the tumor size with hydrocephalus. External ventricular drain insertion plus midline suboccipital craniotomy and resection of the tumor was performed. Pathology revealed MB classic type, sonic hedgehog-activated. There was no cerebrospinal fluid dissemination. link3 He received craniospinal radiation and chemotherapy. Follow-up 20 months after radiation revealed residual neurologic symptoms and no recurrence on MRI brain.
The exceedingly rare coexistence of adult MB and sarcoidosis may have a causal relationship based on specific common molecules. Leukotrienes, stimulation of astrocytes and Purkinje neurons, and the sonic hedgehog signaling pathway can be considered. Further genetic and molecular studies are merited.
