Article Synopsis
  • This study examines the impact of point-of-care ultrasound (PoCUS) on hospital length of stay (LOS) and mortality rates in stable patients experiencing chest pain or dyspnea between June 2020 and May 2021.
  • Out of 465 patients, findings showed that PoCUS had minimal influence on LOS and mortality for those with ST-segment elevation (STE) but significantly reduced LOS and improved survival in non-STE patients, especially when administered within 90 minutes of arrival.
  • The study concluded that while PoCUS is beneficial for non-STE cases and helps identify unforeseen conditions, its effects on STE patients were limited despite a high overall diagnostic accuracy of 96.6%.*

Article Synopsis
  • The study analyzed high-risk revisits to U.S. emergency departments (EDs) from 2010-2018, focusing on those with serious adverse outcomes like ICU admissions or CPR.
  • It found approximately 827,000 high-risk revisits, constituting a stable 0.1% of total ED visits, while overall revisit rates slightly decreased from 5.1% to 4.5%.
  • Factors such as older age (65+), Hispanic ethnicity, daytime visits, and ambulance arrival were identified as significant predictors for these high-risk revisits.

Introduction: Research suggests that pain assessment involves a complex interaction between patients and clinicians. We sought to assess the agreement between pain scores reported by the patients themselves and the clinician's perception of a patient's pain in the emergency department (ED). In addition, we attempted to identify patient and physician factors that lead to greater discrepancies in pain assessment.

Objective: Appropriate triage in patients presenting to the emergency department (ED) is often challenging. Little is known about the role of physician gestalt in ED triage. We aimed to compare the accuracy of emergency physician gestalt against the currently used computerized triage process.

Background: The effects of early integration of point-of-care ultrasound (PoCUS) into patient care are uncertain. This study aims to investigate the effects of early PoCUS on patients with acute flank pain.

Methods: Adult non-traumatic patients with acute flank pain receiving PoCUS were enrolled.

Background: Opioids have been shown to increase risk of pneumonia among susceptible population. However, the effect of opioid abuse on the outcome of pneumonia has not been evaluated at the population level. We aimed to compare the outcomes of pneumonia among patients with opioid use disorder and patients without substance use disorder using a large population database.

Introduction: Protocolized postarrest care that includes targeted temperature management (TTM) improves survival and neurological outcomes in cardiac arrest survivors. Whether the accumulated experience regarding the use of the protocolized approach also benefits patients who did not undergo TTM has yet to be investigated.

Methods: Adults (≥18 years old) with nontraumatic cardiac arrest and who survived to intensive care unit (ICU) admission were retrospectively recruited from a single tertiary medical centre from 2006 to 2009 and 2011 to 2017.

Little is known about the risk of in-hospital cardiac arrest (IHCA) among patients with sepsis. We aimed to characterize the incidence and outcome of IHCA among patients with sepsis in a national database. We then determined the major risk factors associated with IHCA among sepsis patients.

Introduction: Emergency department (ED) revisits are traditionally used to measure potential lapses in emergency care. However, recent studies on in-hospital outcomes following ED revisits have begun to challenge this notion. We aimed to examine inpatient outcomes and resource use among patients who were hospitalized following a return visit to the ED using a national database.

A first example of an sp carbon-conjugated three-dimensional (3D) covalent organic framework (COF) (BUCT-COF-4) is synthesized via the Knoevenagel condensation of the saddle-shaped aldehyde-substituted cyclooctatetrathiophene and 1,4-phenylenediacetonitrile. Ascribed to the extended π-conjugation and long-range ordered structures, BUCT-COF-4 displays high Hall electron mobility of 1.97 cm V s at room temperature.

Background: Small cell lung cancer (SCLC) is characterized by aggressive spread and poor prognosis, but has limited treatment options. Results of prognostic factors from randomized trials on treatment arrangement are conflicting and large-scale real-world analysis is lacking.

Methods: Patients diagnosed SCLC between 2008 and 2018 in Peking University Cancer Hospital were included in this study.

Although π-conjugated two dimensional (2D) covalent organic frameworks (COFs) have been extensively reported, developing fully π-conjugated 3D COFs is still an extremely difficult problem due to the lack of fully π-conjugated 3D linkers. We synthesize a fully conjugated 3D COF (BUCT-COF-1) by designing a saddle-shaped building block of aldehyde-substituted cyclooctatetrathiophene (COThP)-CHO. As a consequence of the fully conjugated 3D network, BUCT-COF-1 demonstrates ultrahigh Hall electron mobility up to ≈3.

Objectives: Emergency department (ED) revisits had traditionally been used as a quality indicator, but focused more on the same hospital revisit (SHRV). Our study investigated the 72-hour ED revisits on SHRV and different hospital revisits (DHRV), and explored the predictors of DHRV.

Methods: 72-hour ED revisits were analyzed using Taiwan's National Health Insurance Research Database that contained one-third patient records from 2012 to 2013.

Circulating fetal nucleated cells (CFNCs) in maternal blood offer an ideal source of fetal genomic DNA for noninvasive prenatal diagnostics (NIPD). We developed a class of nanoVelcro microchips to effectively enrich a subcategory of CFNCs, i.e.

Treatment of locally advanced penile squamous cell carcinoma (pSCC) remains highly controversial secondary to disease rarity and lack of prospective randomized controlled trials. The current mainstays of care are multi-modality treatment with neoadjuvant chemotherapy and surgery. However, clinicians often have difficulty making recommendations for patients unable to tolerate chemotherapy or surgery due to scarcity of data to guide clinical decision-making.
