Regulation of autophagy and cellular signaling through non-histone protein methylation.

Autophagy is a highly conserved catabolic pathway that is precisely regulated and plays a significant role in maintaining cellular metabolic balance and intracellular homeostasis. Abnormal autophagy is directly linked to the development of various diseases, particularly immune disorders, neurodegenerative conditions, and tumors. The precise regulation of proteins is crucial for proper cellular function, and post-translational modifications (PTMs) are key epigenetic mechanisms in the regulation of numerous biological processes.

KHSRP ameliorates acute liver failure by regulating pre-mRNA splicing through its interaction with SF3B1.

Acute liver failure (ALF) is characterized by the rapidly progressive deterioration of hepatic function, which, without effective medical intervention, results in high mortality and morbidity. Here, using proteomic and transcriptomic analyses in murine ALF models, we found that the expression of multiple splicing factors was downregulated in ALF. Notably, we found that KH-type splicing regulatory protein (KHSRP) has a protective effect in ALF.

The impact of recreational cannabis legalization on ED visit rates for acute cannabis intoxication.

Background: In December 2018 the Michigan Regulation and Taxation of Marihuana Act legalized the recreational use of cannabis in Michigan. There are now high potency forms of cannabis readily available in the state, which could result in increased emergency department (ED) visit rates due to intoxication in adults and children. Although cannabis related visits account for a small percentage of all adult and pediatric ED visits, they impose a significant burden on the health care system's resources.

Newly Diagnosed Mental Health Disorders in Patients With Breast Cancer Receiving Radiation Therapy.

Purpose: Patients with a mental health disorder (MHD) have higher age-adjusted mortality compared with the general population. Few reports investigate factors contributing to MHD among patients with breast cancer receiving radiation therapy. We report the incidence of acquired MHD after the diagnosis of breast cancer and treatment with radiation therapy.

Theoretical investigation of the magnetic and optical properties in a transition metal-doped GaTeCl monolayer.

We investigate the structural, magnetic, electronic and optical properties of a transition metal-doped GaTeCl monolayer, denoted as M@GaTeCl (M = V, Cr, Mn, Fe and Co), by using first-principles calculations. It is found that the magnetic ground state can be regulated by different M elements. In the meantime, the electronic structure is different with the doping of different M metal atoms, and thus the optical absorption changes correspondingly.

Histone demethylases in the regulation of immunity and inflammation.

Pathogens or danger signals trigger the immune response. Moderate immune response activation removes pathogens and avoids excessive inflammation and tissue damage. Histone demethylases (KDMs) regulate gene expression and play essential roles in numerous physiological processes by removing methyl groups from lysine residues on target proteins.

ACE2 and Innate Immunity in the Regulation of SARS-CoV-2-Induced Acute Lung Injury: A Review.

Despite the protracted battle against coronavirus acute respiratory infection (COVID-19) and the rapid evolution of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), no specific and effective drugs have to date been reported. Angiotensin-converting enzyme 2 (ACE2) is a zinc metalloproteinase and a critical modulator of the renin-angiotensin system (RAS). In addition, ACE2 has anti-inflammatory and antifibrosis functions.

Vaccination reduces need for emergency care in breakthrough COVID-19 infections: A multicenter cohort study.

Background: While recent literature has shown the efficacy of the SARS-CoV-2 vaccine in preventing infection, it's impact on need for emergency care/hospitalization in breakthrough infections remain unclear, particularly in regions with a high rate of variant viral strains. We aimed to determine if vaccination reduces hospital visits in breakthrough COVID-19.

Methods: This observational cohort analysis compared unvaccinated (UV), partially vaccinated (PV), and fully vaccinated (FV) adult patients with SARS-CoV-2 infection requiring emergency care(EC)/hospitalization within an eight-hospital system in Michigan.

An automated streamlined method for the therapeutic drug monitoring of digoxin based on the online-solid-phase extraction liquid chromatography tandem high-resolution mass spectrometry.

Rationale: Digoxin is widely used in the clinical treatment of cardiovascular diseases. However, due to its extremely narrow therapeutic window, therapeutic drug monitoring (TDM) is vitally important. In consideration of the time-consuming and labor-intensive nature of the traditional techniques, an automated and efficient method was required for the clinical individualized TDM of digoxin.

Glycyrrhizic Acid Alleviates Lipopolysaccharide (LPS)-Induced Acute Lung Injury by Regulating Angiotensin-Converting Enzyme-2 (ACE2) and Caveolin-1 Signaling Pathway.

Acute lung injury (ALI) is mainly caused by severe infection, shock, trauma, and burn, which causes the extensive release of inflammatory factors and other mediators. As a major bioactive constituent of traditional Chinese herb licorice, glycyrrhizic acid (GA) plays an important effect on inflammatory regulation. Nevertheless, the exact mechanism of this effect remains unclear.

Introduction Insufficient attention has been directed towards urosepsis. Notably, no protocols or clinical decision rules currently exist outlining the appropriate use of imaging in uroseptic patients. The primary objective of our study was to retrospectively evaluate uroseptic emergency department (ED) patients who underwent abdominal imaging, to report the proportion of patients with imaging findings necessitating emergent surgical consultation.

Epidemiology, Clinical Characteristics, and Outcomes of a Large Cohort of COVID-19 Outpatients in Michigan.

Background: Most outpatients with coronavirus disease 2019 (COVID-19) do not initially demonstrate severe features requiring hospitalization. Understanding this population's epidemiological and clinical characteristics to allow outcome anticipation is crucial in healthcare resource allocation.

Methods: Retrospective, multicenter (8 hospitals) study reporting on 821 patients diagnosed with COVID-19 by real-time reverse transcriptase-polymerase chain reaction assay of nasopharyngeal swabs and discharged home to self-isolate after evaluation in emergency departments (EDs) within Beaumont Health System in March, 2020.

Inferior Vena Cava Filter Retrieval Trends: A Single-Center Experience.

Recognition of the adverse events of inferior vena cava filters (VCFs) has prompted the Food and Drug Administration (FDA) to issue safety warnings (2010 and 2014), advocating for removal, once the risk of pulmonary embolism has abated. Despite an initial increase in retrieval rates, these remain low (25-30% at 1 year in 2014). We retrospectively investigated retrieval trends in adults with VCFs placed between 2015 and 2018 at a single institution.

Single-molecule multiplexed profiling of protein-DNA complexes using magnetic tweezers.

Epigenetics, such as the dynamic interplay between DNA methylation and demethylation, play diverse roles in critical cellular events. Enzymatic activity at CpG sites, where cytosines are methylated or demethylated, is known to be influenced by the density of CpGs, methylation states, and the flanking sequences of a CpG site. However, how the relevant enzymes are recruited to and recognize their target DNA is less clear.

Opioid ordering habits in the acute emergency department visit: Before and after implementation of departmental prescribing guidelines.

Objective: At our emergency department (ED), opioid prescribing guidelines were implemented in September 2016. The opioid prescribing guidelines were adopted and revised from collective efforts and advocacy of the Michigan College of Emergency Physicians for ED-led opioid stewardship. We performed a retrospective before and after study to determine if opioid prescribing guidelines would change the use of intravenous opioids per patient and the morphine equivalent units (MEU) per patient in a suburban academic ED.

Assessing the impact of resuscitation residents on the treatment of cardiopulmonary resuscitation patients.

Background: The management of cardiac arrest patients receiving cardiopulmonary resuscitation (CPR) is an essential aspect of emergency medicine (EM) training. At our institution, we have a 1-month Resuscitation Rotation designed to augment resident training in managing critical patients. The objective of this study is to compare 30-day mortality between cardiac arrest patients with resuscitation resident (RR) involvement versus patients without.

Doomed peripheral intravenous catheters: Bad Outcomes are similar for emergency department and inpatient placed catheters: A retrospective medical record review.

Introduction: The survivorship of peripheral intravenous catheters (PIVCs) placed in hospitalized patients is shockingly poor and leads to frequent reinsertions. We aimed to evaluate differences in failure rates and IV insertion practices for PIVCs that are placed in the emergency department (ED) compared to those placed in the inpatient (IP) setting.

Methods: We conducted a retrospective electronic medical record review of PIVC survival at a single-site suburban, academic tertiary care referral center with 130,000 annual ED visits and 1100 inpatient beds.
