Thromboembolic Events in the Hemodialysis Setting: Understanding Risk Profiles and Cumulative Incidences to Inform Clinical Trial Design.

Background: People with kidney failure have a high risk of cardiovascular morbidity/death, including thromboembolic events. Factor XIa inhibitors are a new class of anticoagulants in development that may offer antithrombotic benefits with a lower risk of incremental bleeding events than traditional therapies. We investigated major adverse vascular events (MAVEs), a relevant composite outcome for testing novel antithrombotic agents, in a large cohort of patients on hemodialysis, to better understand the key requirements to adequately design a phase 3 trial.

Galactosamine and mannosamine are integral parts of bacterial and fungal extracellular polymeric substances.

Extracellular polymeric substances (EPS) are produced by microorganisms and interact to form a complex matrix called biofilm. In soils, EPS are important contributors to the microbial necromass and, thus, to soil organic carbon (SOC). Amino sugars (AS) are used as indicators for microbial necromass in soil, although the origin of galactosamine and mannosamine is largely unknown.

Effects of supplementing direct-fed microbials on health and growth of preweaning Gyr × Holstein dairy calves.

This study aimed to evaluate the effects of direct-fed microbials (DFM) on health and growth responses of preweaning Bos indicus × Bos taurus (Gyr × Holstein) crossbred calves. Ninety newborn heifer calves (initial BW of 35 ± 4.0 kg) were used.

Effects of supplementing a -based direct-fed microbial on performance, nutrient digestibility, rumen fermentation characteristics, and metabolic responses of lactating dairy cows.

This experiment was conducted to evaluate the effects of feeding a -based direct-fed microbial (DFM) on performance, nutrient digestibility, rumen fermentation, and metabolic response of lactating dairy cows. Sixty-eight lactating (50 ± 6 d in milk) Holstein-Friesian (n = 20) and Swedish Red (n = 48) cows were enrolled to a 15-wk experiment. Cows were blocked by breed, lactation number, and days in milk and, within blocks, assigned to 1 of the 2 treatments: (1) basal partial mixed ration (PMR) without DFM (n = 34; CON) or (2) basal PMR with the addition of 3 g/head per day of a DFM containing and (n = 34; DFM).

Differences in politeness perception of irony and prosocial lies: Exploring the role of age, gender, and geographic location.

In daily interactions, individuals use irony and prosocial lies for various reasons, for example, to be humorous, to criticize, or to be polite. While some studies have examined individual differences in perceiving the politeness of such language, research using naturalistic, context-rich materials is lacking. To address this gap, we utilized short videos to assess politeness perception in literal, ironic, and prosocial lie scenarios while also exploring differences based on age, gender, and geographical location.

Percutaneous thoracostomy with thoracic lavage for traumatic hemothorax: a performance improvement initiative.

Objectives: Percutaneously placed small-bore (14 Fr) catheters and pleural lavage have emerged independently as innovative approaches to hemothorax management. This report describes techniques for combining percutaneous thoracostomy with pleural lavage and presents results from a performance improvement series of patients managed with percutaneous thoracostomy with immediate lavage.

Methods: This was a prospective performance improvement series of patients treated at a level 1 trauma center with percutaneous thoracostomy and immediate lavage between April 2021 and May 2023.

Thromboembolic Complications Following Perioperative Tranexamic Acid Administration.

Introduction: The antifibrinolytic tranexamic acid (TXA) may reduce death in trauma; however, outcomes associated with TXA use in patients without proven hyperfibrinolysis remain unclear. We analyzed the associations of empirically administered TXA, hypothesizing that TXA use would correlate to lower transfusion totals but increased thromboembolic complications.

Methods: This retrospective cohort study compared trauma patients started on massive transfusion protocol at a Level I trauma center from 2016 to 2021 who either did or did not receive TXA.

Brain-derived extracellular vesicles as serologic markers of brain injury following cardiac arrest: A pilot feasibility study.

Aim: Assessment of neurologic injury within the immediate hours following out-of-hospital cardiac arrest (OHCA) resuscitation remains a major clinical challenge. Extracellular vesicles (EVs), small bodies derived from cytosolic contents during injury, may provide the opportunity for "liquid biopsy" within hours following resuscitation, as they contain proteins and RNA linked to cell type of origin. We evaluated whether micro-RNA (miRNA) from serologic EVs were associated with post-arrest neurologic outcome.

Brief report on the development of hemorrhagic pericardial effusion after thoracic surgery for traumatic injuries.

Introduction: Hemorrhagic pericardial effusion (HPE) is a rare but life-threatening diagnosis that may occur after thoracic trauma. Previous reports have concentrated on delayed HPE in those who did not require initial surgical intervention for their traumatic injuries. In this report, we identify and characterize the phenomenon of HPE after emergent thoracic surgery for trauma.

Investigating the Extent to which Distributional Semantic Models Capture a Broad Range of Semantic Relations.

Distributional semantic models (DSMs) are a primary method for distilling semantic information from corpora. However, a key question remains: What types of semantic relations among words do DSMs detect? Prior work typically has addressed this question using limited human data that are restricted to semantic similarity and/or general semantic relatedness. We tested eight DSMs that are popular in current cognitive and psycholinguistic research (positive pointwise mutual information; global vectors; and three variations each of Skip-gram and continuous bag of words (CBOW) using word, context, and mean embeddings) on a theoretically motivated, rich set of semantic relations involving words from multiple syntactic classes and spanning the abstract-concrete continuum (19 sets of ratings).

Multidrug resistance protein 1 silencing in osteosarcoma and chondrosarcoma cell lines.

Background: The poor response of metastatic osteo- and chondrosarcomas to chemotherapy could be the result of multidrug resistance (MDR), which may be overcome through the use of small interfering RNA (siRNA). However, several methodologic questions remain unresolved.

Aims: To test the toxicity of three commonly used siRNA transfection reagents and apply the least toxic reagent to investigate the siRNA-induced MDR1 mRNA knockdown.

Genomic analysis of firework fear and noise reactivity in standard poodles.

Background: Fear of firework noises and other loud, sudden noises (noise reactivity) is a significant problem for many dogs and may have a negative effect on both welfare and, in severe cases, the life expectancy of dogs. A wide range of behavior traits, including fear-related behaviors, have high heritability estimates in dogs. The aim of this study was to estimate genomic heritability for fear of fireworks and loud noises in dogs.

Danger Zone or Newfound Freedoms: Exploring Women and Girls' Experiences in the Virtual Space during COVID-19 in Iraq.

During the COVID-19 pandemic, women and girls across the globe faced increased reliance on the digital space to access education, social support, and health and gender-based violence (GBV) services. While research from the last three years has explored how women and girls navigated and responded to their new virtual reality, minimal evidence has been generated from low-resource settings where access to technology may be limited. Further, no studies to date have examined these dynamics in Iraq, where women and girls already face numerous threats to safety due to various forms of structural violence and patriarchal family structures.
