Hangings are an infrequent wounding mechanism among patients arriving alive to hospital but are frequently encountered by the Coroner's Office. It is unclear if classically described hanging injuries, such as the Hangman's fracture, are common among contemporary hangings patients who typically do not suspend from height. This study was undertaken to define patient and injury characteristics after hangings causing death.

All patients presenting to the Los Angeles County Medical Examiner/Coroner's Office (January 2016 - May 2020) who died by hanging were included. Demographics, psychiatric history, hanging details, autopsy type, and sustained injuries were collected. Data variables were summarized with descriptive statistics and the diagnostic yield of a ligature mark in the diagnosis/exclusion of cervical injuries was calculated.

Over the study, 1,401 patients died by hanging. Patients underwent external exam alone (n=1,282, 92%), traditional neck autopsy (n=114, 8%), or traditional neck autopsy plus posgings are a frequent cause of death in Los Angeles County. OD36 concentration Patients typically have a psychiatric history and die almost exclusively from suicide. Hangings commonly occur at home, in public places, and in jail. Injuries were exceedingly rare and no patient sustained a Hangman's fracture, which may be related to the lack of significant suspension with modern hangings.

Palliative care in trauma patients is still evolving. The goal was to compare characteristics, outcomes, triggers and timing for palliative care consultations (PCC) in geriatric (≥65 y.o.) and non-geriatric trauma patients.

Retrospective study included 432 patients from two level 1 trauma centers who received PCC between December 2012 and January 2019. Non-geriatric (n=61) and geriatric (n=371) groups were compared for mechanism of injury (MOI), Injury Severity Score (ISS), Revised Trauma Score (RTS), Glasgow Coma Score (GCS), Do-Not-Resuscitate (DNR) orders, futile interventions (FI), duration of mechanical ventilation (DMV), ICU admissions, ICU and hospital lengths of stay (ICULOS; HLOS), timing to PCC, and mortality. Further propensity matching (PM) analysis compared 59 non-geriatric to 59 Geriatric patients matched by ISS, GCS, and DNR.

Geriatric patients were older (85.2 versus 49.7), with falls as predominant MOI. Non-geriatric patients comprised 14.1% of all patients with PCC and were more severed more aggressive treatment, and had three times longer time to PCC, resulting in higher rate of FI than in Geriatrics.

Operating room (OR) efficiency, often measured by first case on-time start (FCOTS) percentage, is an important driver of perioperative team morale and the financial success of a hospital.

In this quasi-experimental study of elective surgical procedures at a single tertiary academic hospital, an intervention requiring attending surgeon attestation of availability via SMS text message or identification badge swipe was implemented. Key measures of OR efficiency were compared before and after the change.

FCOTS percentage increased from 61.6% to 66.9% after the intervention (P = 0.01). After adjusting for patient and procedural characteristics, postintervention period remained associated with an increased odds of an on-time start (odds ratio 1.29, P = 0.01). Additionally, procedural start times from the pre- to postintervention period were significantly improved (-0.08 min/day, P = 0.009).

Implementation of an attending surgeon text or badge sign-in process was associated with improved FCOTS percentage and earlier procedure start times.

Se deprivation can lead to many disorders and even death. This study investigated the response of Przewalski's gazelle (P. przewalskii) to Se-deprived environment. We found that Se deprivation in soil and forage not only influenced the mineral contents of the blood and hair in P. przewalskii, but also severely disrupted their blood parameters. We identified significant changes in the abundance of 146 proteins and 25 metabolites (P less then 0.05) in serum, including the selenoproteins L8IG93 (glutathione peroxidase) and F4YD09 (Cu/Zn superoxide dismutase). Furthermore, the major known proteins and metabolites associated with the Se stress response in P. przewalskii were Cu/Zn superoxide dismutase, the vitamin K-dependent protein C, the C4b-binding protein alpha chain, complement component C7, lipase linoleic acid, peptidase D, thymidine, pseudo-uridine, L-phenylalanine, L-glutamine, PGA1, and 15-deoxy-delta-12,14-PGJ2. The main signaling pathways involved included complement and coagulation cascades, metabolic pathways, and stress granule formation. Our results indicate that the intake of Se-deficient forage elicited an oxidative stress response in P. przewalskii. These findings provide insights into the response mechanisms of this threatened gazelle to Se stress, and enable the development of conservation strategies to protect populations on the Qinghai-Tibetan Plateau. link2 SIGNIFICANCE This study is the first to point out the presence of oxidative stress in P. przewalskii in selenium-deficient areas through proteomics and metabolomics studies. These findings should prove helpful for conservation efforts aimed at P. przewalskii populations and maintenance of the integrity of their ecological environment.Faecal proteomics studies have focussed on identification of microbial proteins, however; stool represents a valuable resource to interrogate the host interactions with the microbiota without the need for invasive intestinal biopsies. As the widely used enrichment method (differential centrifugation, DC) enriches for microbial proteins, we compared two other methods for enrichment of host proteins, termed 'host enriched' (HE) and ALL (all proteins). link3 The HE and ALL protocols identified 1.8-fold more host proteins than DC while detecting a similar number of microbial proteins, but the methods had limited overlap in the specific microbial proteins detected. To maximize identification of both host and microbial proteins, samples were subjected to HE and the remaining material was used to perform DC. These two fractions displayed large differences in relative taxonomic abundance and cellular compartmentalization, with proteins from Bacteroidales and extracellular vesicles were enriched in the soluble HE component. The combination of data generated from these two fractions may allow identification of more distinct proteins than simply performing samples in duplicate or more complex fractionation techniques, or a single fraction could be chosen to suit the experimental hypothesis. SIGNIFICANCE We compared how different stool protein preparation methods influenced the taxonomic and functional characteristics of microbial and host proteins identified. Surprisingly, a method designed to enrich for host proteins recovered a similar number of microbial protein groups to the method that specifically enriched intact bacterial cells. However, the taxonomic and subcellular origin of the microbial proteins differed considerably between the methods. By implementing a two-step method, we could maximize recovery of both host and microbial proteins derived from different cellular compartments and taxa.Wound repair is a multistep process which involves coordination of multiple molecular players from different cell types and pathways. Though the cellular processes that are taking place in order to repair damage is already known, molecular players involved in crucial pathways are still scarce. In this regard, the present study intends to uncover crucial players that are involved in the central repair events through proteomics approach which included 2-D GE and LC-MS/MS using Caenorhabditis elegans wound model. Initial gel-based 2-D GE and following protein-protein interaction (PPI) network analyses revealed active role of calcium signaling, acetylcholine transport and serotonergic neurotransmitter pathways. Further, gel-free LC-MS/MS and following PPI network analyses revealed the incidence of actin nucleation at the initial hours immediately after injury. Further by visualizing the PPI network and the interacting players, pink-1, a mitochondrial Serine/threonine-protein kinase which is known to regulate mitochondrial dynamics, was found to be the central player in facilitating the mitochondrial fission and its role was further verified using qPCR analysis and pink-1 transgenic worms. Overall, the study delivers new insights from crucial regulatory pathways and central players involved in wound repair using high throughput proteomic approaches and the mass spectrometry Data (PXD024629/PXD024744) are available via ProteomeXchange. SIGNIFICANCE.Over the last two decades, intrinsically disordered proteins and protein regions (IDRs) have emerged from a niche corner of biophysics to be recognized as essential drivers of cellular function. Various techniques have provided fundamental insight into the function and dysfunction of IDRs. Among these techniques, single-molecule fluorescence spectroscopy and molecular simulations have played a major role in shaping our modern understanding of the sequence-encoded conformational behavior of disordered proteins. While both techniques are frequently used in isolation, when combined they offer synergistic and complementary information that can help uncover complex molecular details. Here we offer an overview of single-molecule fluorescence spectroscopy and molecular simulations in the context of studying disordered proteins. We discuss the various means in which simulations and single-molecule spectroscopy can be integrated, and consider a number of studies in which this integration has uncovered biological and biophysical mechanisms.Fully convolutional networks (FCNs), including UNet and VNet, are widely-used network architectures for semantic segmentation in recent studies. However, conventional FCN is typically trained by the cross-entropy or Dice loss, which only calculates the error between predictions and ground-truth labels for pixels individually. This often results in non-smooth neighborhoods in the predicted segmentation. This problem becomes more serious in CT prostate segmentation as CT images are usually of low tissue contrast. To address this problem, we propose a two-stage framework, with the first stage to quickly localize the prostate region, and the second stage to precisely segment the prostate by a multi-task UNet architecture. We introduce a novel online metric learning module through voxel-wise sampling in the multi-task network. Therefore, the proposed network has a dual-branch architecture that tackles two tasks (1) a segmentation sub-network aiming to generate the prostate segmentation, and (2) a voxel-metric learning sub-network aiming to improve the quality of the learned feature space supervised by a metric loss.
