Abstract	To present a physiological algorithmic approach to weaning of invasive ventilation in the neonatal intensive care, focusing mainly on the preterm infant. Review of literature, consensus guidelines, expert commentaries and practice guidelines from individual units. Weaning of ventilation for extubation in the neonatal population must follow certain criteria but needs individualising based on disease process, timeline and physiology. Algorithms based on scenarios and modes of ventilation used might aid the clinician on the floor for decision-making process.

Abstract	In spatially structured microbial communities, clonal growth of stationary cells passively generates clusters of related individuals. This can lead to stable cooperation without the need for recognition mechanisms. However, recent research suggests that some biofilm-forming microbes may have mechanisms of kin recognition. To explore this unexpected observation, we studied the effects of different types of cooperation in a microbial colony using spatially explicit, agent-based simulations of two interacting strains. We found scenarios that favor a form of kin recognition in spatially structured microbial communities. In the presence of a "cheater" strain, a strain with greenbeard cooperation was able to increase in frequency more than a strain with obligate cooperation. This effect was most noticeable in high density colonies and when the cooperators were not as abundant as the cheaters. We also studied whether a polychromatic greenbeard, in which cells only cooperate with their own type, could provide a numerical benefit beyond a simple, binary greenbeard. We found the greatest benefit to a polychromatic greenbeard when cooperation is highly effective. These results suggest that in some ecological scenarios, recognition mechanisms may be beneficial even in spatially structured communities.

Abstract	Improvements in diagnostic and therapeutic modalities of antenatal care has meant that the neonatal intensive care units (NICU) need to care for infants with complex congenital conditions who need ongoing care post discharge. This, along with improved survival of the extreme preterm infants, provides the neonatal team with a cohort of infants who require long-standing multi-disciplinary input. However, provision of dedicated teams looking after infants with complex medical needs is not commonly reported in NICU workforce structure. The objective of this study is to perform a scoping review of literature on the presence of structured and dedicated complex care management teams in neonatal intensive care unit and their outcomes on care delivery. A scoping review was undertaken to identify all reported literature on existence of chronic care teams in NICU searching medical databases. A narrative synthesis of results was prepared. Conclusions: The review identified very few clinical models reported with no robust data on clinical outcome measures. What is Known: • Neonatal units are increasingly providing care for infants who require chronic ongoing input from multiple specialties or allied health professionals. A majority of this cohort is formed by extreme preterm infants who require long term respiratory support or nutritional rehabilitation. • There are examples of dedicated clinical teams looking after complex patients in adult and pediatric intensive care outfits leading to improvements in outcome. What is New: • This is first literature review in the authors' knowledge on the use of complex care teams in neonatal intensive care unit. • This article provides a narrative synthesis of the clinical models that have been used by complex care teams in neonatal intensive care unit and whether they have demonstrated tangible benefits in patient outcome.

Abstract	Inspired by strategies like Active Learning, it is intuitive that intelligently selecting the training classes from a dataset for Zero-Shot Learning (ZSL) can improve the performance of existing ZSL methods. In this work, we propose a framework called Diverse and Rare Class Identifier (DiRaC-I) which, given an attribute-based dataset, can intelligently yield the most suitable "seen classes" for training ZSL models. DiRaC-I has two main goals - constructing a diversified set of seed classes, followed by a visual-semantic mining algorithm initialized by these seed classes that acquires the classes capturing both diversity and rarity in the object domain adequately. These classes can then be used as "seen classes" to train ZSL models for image classification. We adopt a real-world scenario where novel object classes are available to neither DiRaC-I nor the ZSL models during training and conducted extensive experiments on two benchmark data sets for zero-shot image classification - CUB and SUN. Our results demonstrate DiRaC-I helps ZSL models to achieve significant classification accuracy improvements. Comment: 22 pages, 10 Figures

Article ; Online: Histogram analysis for bedside respiratory monitoring in not critically ill preterm neonates: a proposal for a new way to look at the monitoring data.

Abstract	Despite robust evidence in favour of maintaining optimal oxygen saturation targets in the preterm infants, the titration of oxygen is largely dependent on manual observations and transcription. Similarly, notwithstanding the gaining popularity of non-invasive modalities like high-flow nasal therapy, the practices of weaning and escalating support are largely individualized and based on point of care observations. These are often erroneous and lack objectivity. Histogram analysis from patient monitors is an easy and objective way of quantifying vital parameters and their trends. We review the technology and evidence available behind this practice.Conclusions: Though there are no randomized controlled trials on this practice solely, we identify several quality improvement studies implementing this into practice with benefit. We also cite studies which have implemented histogram analysis in methodology, thus concluding that this is a useful clinical tool worth incorporating into clinical practice to reduce manual errors and bring more objectivity into decisions. What is Known: • The data from NeOProM (Neonatal Oxygenation Prospective Meta-analysis Collaboration study protocol) indicates that optimal saturation targets for preterm infants born < 28 weeks should be between 91 and 95%. • The most "failsafe" way of maintaining strict compliance to these limits is automated oxygen titration but this is not widely used or available and manual transcription and monitoring are susceptible to error and fatigue. What is New: • Histogram analysis from patient monitors can provide intelligent data on respiratory monitoring and can be incorporated into algorithm to decide on weaning or escalation of respiratory support. • With appropriate training, histogram monitoring by nursing staff can limit fatigue of manual recording of data.

Abstract	Background: Diverse architectures of nervous systems (NSs) such as a plexus in cnidarians or a more centralized nervous system (CNS) in insects and vertebrates are present across Metazoa, but it is unclear what selection pressures drove evolution and diversification of NSs. One underlying aspect of this diversity lies in the cellular and molecular mechanisms driving neurogenesis, i.e. generation of neurons from neural precursor cells (NPCs). In cnidarians, vertebrates, and arthropods, homologs of SoxB and bHLH proneural genes control different steps of neurogenesis, suggesting that some neurogenic mechanisms may be conserved. However, data are lacking for spiralian taxa. Results: To that end, we characterized NPCs and their daughters at different stages of neurogenesis in the spiralian annelid Capitella teleta. We assessed cellular division patterns in the neuroectoderm using static and pulse-chase labeling with thymidine analogs (EdU and BrdU), which enabled identification of NPCs that underwent multiple rounds of division. Actively-dividing brain NPCs were found to be apically-localized, whereas actively-dividing NPCs for the ventral nerve cord (VNC) were found apically, basally, and closer to the ventral midline. We used lineage tracing to characterize the changing boundary of the trunk neuroectoderm. Finally, to start to generate a genetic hierarchy, we performed double-fluorescent in-situ hybridization (FISH) and single-FISH plus EdU labeling for neurogenic gene homologs. In the brain and VNC, Ct-soxB1 and Ct-neurogenin were expressed in a large proportion of apically-localized, EdU Conclusions: Our data suggest a putative genetic hierarchy with Ct-soxB1 and Ct-neurogenin at the top, followed by Ct-ash1, then Ct-neuroD, and finally Ct-elav1. Comparison of our data with that from Platynereis dumerilii revealed expression of neurogenin homologs in proliferating NPCs in annelids, which appears different than the expression of vertebrate neurogenin homologs in cells that are exiting the cell cycle. Furthermore, differences between neurogenesis in the head versus trunk of C. teleta suggest that these two tissues may be independent developmental modules, possibly with differing evolutionary trajectories.

Abstract	Millions of central lines are placed each year worldwide for life-saving measures. We present a case of left internal jugular (IJ) triple lumen catheter (TLC) placement for life-saving vasopressors, which appeared to be in the left mediastinum after a confirmed chest X-ray. After correlation with a previous MRI of the heart with and without contrast, duplication of the superior vena cava (SVC), also known as persistent left SVC (PLSVC), was discovered. PLSVC often causes no symptoms to affected individuals and is usually first found as an incidental finding discovered during thoracic surgeries, cardiovascular interventional procedures, and central line insertions. Placement of TLC or central venous catheter (CVC) can be challenging in such patients and may lead to life-threatening complications such as severe arrhythmias, cardiogenic shock, pneumothorax, and tamponade. Knowing such anomalies can prevent unnecessary catheter removal and help determine the origin of some arrhythmias and dilated heart chambers in these patients.

Abstract	During development, animals generate distinct cell populations with specific identities, functions, and morphologies. We mapped transcriptionally distinct populations across 489,686 cells from 62 stages during wild-type zebrafish embryogenesis and early larval development (3-120 hours post-fertilization). Using these data, we identified the limited catalog of gene expression programs reused across multiple tissues and their cell-type-specific adaptations. We also determined the duration each transcriptional state is present during development and suggest new long-term cycling populations. Focused analyses of non-skeletal muscle and the endoderm identified transcriptional profiles of understudied cell types and subpopulations, including the pneumatic duct, individual intestinal smooth muscle layers, spatially distinct pericyte subpopulations, and homologs of recently discovered human
