Background: Trauma-induced hypocalcemia is common and associated with adverse outcomes, but the mechanisms remain unclear. Thus, we aimed to characterize the metabolomic and proteomic differences between normocalcemic and hypocalcemic trauma patients to illuminate biochemical pathways that may underlie a distinct pathology linked with this clinical phenomenon. Methods: Plasma was obtained on arrival from injured patients at a Level 1 Trauma Center.

This study will develop, implement, and evaluate Canadian Clinical Practice Guidelines for ED transition, including identifying the relevant measurement and evaluation tools for transition readiness and continuity of care.
Methods: This study consists of three phases.
Oxygenation is a crucial indicator of tissue viability and function. Oxygen tension ([Formula: see text]), i.e.

Imprinted genes are central to placental development and are thought to contribute to the evolution of reproductive barriers between species. However, it is unclear how rapidly imprinting evolves or how functional specialization among placental tissues influences the evolution of imprinted expression.

This study aimed to measure the radiographic change in pulmonary contusions over time and evaluate the association of the radiographic change with clinical outcomes and surgical stabilization of rib fractures (SSRF).
Methods: This retrospective cohort study included adults admitted with three or more displaced rib fractures or flail segment on trauma CT and when a chest CT was repeated within one week after trauma.
The greatest known risk factor for Alzheimer's disease (AD) is age. While both normal aging and AD pathology involve structural changes in the brain, their trajectories of atrophy are not the same. Recent developments in artificial intelligence have encouraged studies to leverage neuroimaging-derived measures and deep learning approaches to predict brain age, which has shown promise as a sensitive biomarker in diagnosing and monitoring AD.

This study leveraged a trans-omics analysis of longitudinal samples from trauma patients to illuminate molecular endotypes and trajectories that underpin patient outcomes, transcending traditional demographic and physiological characterizations. We hypothesize that trans-omics profiling reveals underlying clinical differences in severely injured patients that may present with similar clinical characteristics but ultimately have very different responses to treatment and clinical outcomes.
View Article and Find Full Text PDFTranscription of ribosomal RNA (rRNA) by RNA Polymerase (Pol) I in the nucleolus is necessary for ribosome biogenesis, which is intimately tied to cell growth and proliferation. Perturbation of ribosome biogenesis results in tissue specific disorders termed ribosomopathies in association with alterations in nucleolar structure. However, how rRNA transcription and ribosome biogenesis regulate nucleolar structure during normal development and in the pathogenesis of disease remains poorly understood.

Background: Regionalization of trauma care saves lives. The underlying concept driving this is a volume-outcome relationship.
Marginal zone lymphoma (MZL) is a primary, indolent small B-cell lymphoma. Subtypes include nodal, splenic, and those of extranodal mucosa-associated lymphoid tissue (MALT). These are slow growing and generally exhibit low rates of transformation to diffuse large B-cell lymphoma (DLBCL).

Objective: To explore the association of maternal T2D and gestational diabetes mellitus (GDM) with childhood anthropometry, and the influence of maternal BMI on these associations.
Methods: The PANDORA cohort comprises women (n = 1138) and children (n = 1163).
Background: The diagnostic performance of multiple tests for detecting the presence of a main pancreatic duct injury remains poor. Given the central importance of main duct integrity for both subsequent treatment algorithms and patient outcomes, poor test reliability is problematic. The primary aim was to evaluate the comparative test performance of computed tomography (CT), magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), and intraoperative ultrasound (IOUS) for detecting main pancreatic duct injuries.
View Article and Find Full Text PDFBackground: Eating patterns such as breakfast consumption and fruit and vegetable intake have been associated with academic achievement and cognitive function.
Method: The purpose of this study was to learn more about psychological (emotion-driven eating) and behavioral (over-eating) eating patterns and motives, and the roles of body image, academic achievement (reading and math), and social supports (peer acceptance and school attachment), among 378 fourth-grade students (55% boys) from 14 classrooms across 6 schools within a large Midwestern urban area.
Results: Results were analyzed through a 2-group (male and female) path analysis.
Among various super-resolution microscopic techniques, structured illumination microscopy (SIM) stands out for live-cell imaging because of its higher imaging speed. However, conventional SIM lacks optical sectioning capability. Here we demonstrate a new, to the best of our knowledge, approach using a phase-modulated spinning disk (PMSD) that enhances the optical sectioning capability of SIM.

However, research on male athletes' BS and ED/DE is limited, particularly in relation to times of transition, such as occurred in the months immediately following COVID-19 being recognized as a global pandemic. In this study, we surveyed 1975 male collegiate athletes in April/May 2020 to assess their body satisfaction and ED/DE symptomatology to determine prevalence and prediction between the two.

Incisional hernia (IH) is a late manifestation of the failure of abdominal wall closure and represents frequent complication of any abdominal incision: IHs can cause pain and discomfort to the patients but also clinical serious sequelae like bowel obstruction, incarceration, strangulation, and necessity of reoperation. Previous guidelines and indications in the literature consider elective settings and evidence about laparotomy closure in emergency settings is lacking.

The study sought to evaluate risk of recurrence in relation to the mastectomy surgical margin.
Methods: A single institution retrospective review of patients with DCIS who underwent mastectomy between 2000 and 2010 was performed.
