OBJECTIVE Guidelines following median sternotomy typically include strict sternal precautions (SP). Recently, alternative approaches propose less functional restrictions while avoiding excessive stress to the sternum. The study aimed to determine the effect of a less restrictive (LR) approach versus a standard sternal precautions protocol after median sternotomy. METHODS The study was a cross-sectional design (n = 364; SP n = 172, 66.3 ± 11.2 y; LR n = 196, 65.2 ± 11.2 y). This study ran in 2 consecutive phases and compared 2 groups post median sternotomy at a community-based hospital. The LR group received instructions on the Keep Your Move in the Tube™ approach. At 2-3 weeks post discharge, sternal instability was assessed using the Sternal Instability Scale (SIS), and patients completed a self-reported survey (perceived pain rating/frequency, sternal instability, and functional mobility). The 2 groups were compared using the Mann Whitney U test and Chi square test (P less then 0.05). RESULTS There were no significant differences between the 2 groups for all the outcomes, SIS, pain rating, pain frequency, perceived sternal instability, difficulty with functional mobility, length of stay, and discharge disposition. CONCLUSIONS In our study, the implementation of the LR approach, Keep Your Move in the Tube™, had no adverse effect on outcomes 2 to 3 weeks following median sternotomy. Although no statistically significant differences were noted for all outcomes, patients with the LR approach reported less difficulty with functional mobility. IMPACT These data are useful in clinical decision making regarding alternative apporaches for mobility following sternotomy. © The Author(s) 2020.

The primary objective of this study was to determine the interrater reliability of muscle ultrasound image acquisition by physical therapists and physical therapist students. Secondarily, this study was designed to elucidate the process for training physical therapists to perform peripheral skeletal muscle ultrasonography. METHODS This was a cross-sectional observational study. Four novice and 1 expert participated in the study. Novice sonographers engaged in a structured training program prior to implementation. Ultrasound images were obtained on the biceps brachii, quadriceps femoris, and tibialis anterior muscles in 3 groups patients in the intensive care unit (ICU), patients on the hospital ward, and participants in the outpatient gym who were healthy. Reliability of image acquisition was analyzed in comparison to the expert sonographer. RESULTS [email protected] characterization of genetic variants of a large population of individuals within the same species is essential to have a deeper insight into its evolutionary history as well as the genotype-phenotype relationship. Population genomic surveys have been performed in multiple yeast species, including the two model organisms, Saccharomyces cerevisiae and Schizosaccharomyces pombe. In this context, we sought to characterize at the population level the Brettanomyces bruxellensis yeast species, which is a major cause of wine spoilage but also can contribute to the specific flavor profile of some Belgium beers. We have completely sequenced the genome of 53 B. Etomoxir solubility dmso bruxellensis strains isolated worldwide. The annotation of the reference genome allowed us to define the gene content of this species. As previously suggested, our genomic data clearly highlighted that genetic diversity variation is related to ploidy level, which is variable in the B. bruxellensis species. Genomes are punctuated by multiple loss-of-heterozygosity regions while aneuploidies as well as segmental duplications are uncommon. Interestingly, triploid genomes are more prone to gene copy number variation than diploids. Finally, the pangenome of the species was reconstructed and was found to be small with few accessory genes compared to S. cerevisiae. The pangenome is composed of 5,409 ORFs among which 5,106 core ORFs and 303 ORFs that are variable within the population. All these results highlight the different trajectories of species evolution and consequently the interest of establishing population genomic surveys in more populations. © The Author(s) 2020.

In this Perspective, autopsy results and literature are presented supporting the hypothesis that a little known yet powerful function of neutrophils-the ability to form neutrophil extracellular traps (NETs)-may contribute to organ damage and mortality in COVID-19. We show lung infiltration of neutrophils in an autopsy specimen from a patient who succumbed to COVID-19. We discuss prior reports linking aberrant NET formation to pulmonary diseases, thrombosis, mucous secretions in the airways, and cytokine production. If our hypothesis is correct, targeting NETs directly and/or indirectly with existing drugs may reduce the clinical severity of COVID-19. © 2020 Barnes et al.The proliferative activity of aging hematopoietic stem cells (HSCs) is controversially discussed. Inducible fluorescent histone 2B fusion protein (H2B-FP) transgenic mice are important tools for tracking the mitotic history of murine HSCs in label dilution experiments. A recent study proposed that primitive HSCs symmetrically divide only four times to then enter permanent quiescence. We observed that background fluorescence due to leaky H2B-FP expression, occurring in all H2B-FP transgenes independent of label induction, accumulated with age in HSCs with high repopulation potential. We argue that this background had been misinterpreted as stable retention of induced label. We found cell division-independent half-lives of H2B-FPs to be short, which had led to overestimation of HSC divisional activity. Our data do not support abrupt entry of HSCs into permanent quiescence or sudden loss of regeneration potential after four divisions, but show that primitive HSCs of adult mice continue to cycle rarely. © 2020 Morcos et al.
