Garbage In, Garbage Out? Negative Impact of Physiological Waveform Artifacts in a Hospital Clinical Data Warehouse.

Hospitals around the world are deploying increasingly advanced systems to collect and store high-resolution physiological patient data for quality improvement and research. However, data accuracy, completeness, consistency, and contextual validity remain issues. This report highlights a data artifact known as waveform clipping in our hospital's physiological data capture system that went unnoticed for years, limiting data analysis and delaying several research projects.

Anesthesia for Posterior Tracheopexy in Pediatric Patients.

Tracheobronchomalacia refers to an abnormally excessive collapse of the trachea and/or bronchi during exhalation. In the pediatric population, tracheobronchomalacia is increasingly recognized as a cause of morbidity and mortality. Historically, options for medical management and surgical intervention were limited, and patient outcomes were poor.

Comparing ChatGPT and a Single Anesthesiologist's Responses to Common Patient Questions: An Exploratory Cross-Sectional Survey of a Panel of Anesthesiologists.

Increased patient access to electronic medical records and resources has resulted in higher volumes of health-related questions posed to clinical staff, while physicians' rising clinical workloads have resulted in less time for comprehensive, thoughtful responses to patient questions. Artificial intelligence chatbots powered by large language models (LLMs) such as ChatGPT could help anesthesiologists efficiently respond to electronic patient inquiries, but their ability to do so is unclear. A cross-sectional exploratory survey-based study comprised of 100 anesthesia-related patient question/response sets based on two fictitious simple clinical scenarios was performed.

Precision Anesthesia in 2050.

Over the last few decades, the field of anesthesia has advanced far beyond its humble beginnings. Today's anesthetics are better and safer than ever, thanks to innovations in drugs, monitors, equipment, and patient safety.1-4 At the same time, we remain limited by our herd approach to medicine.

Negative pressure suction test: An intraoperative airway maneuver to assess effectiveness of surgical correction of tracheobronchomalacia.

Background: Surgical correction of tracheobronchomalacia (TBM) has evolved greatly over the past decade, with select pediatric institutions establishing dedicated surgery and anesthesia teams to navigate the complexities and challenges of surgical airway repairs. Although anesthetic techniques have evolved internally over many years to improve patient safety and outcomes, many of these methods remain undescribed in literature.

Technique: In this article, we describe the intraoperative negative pressure suction test.

Risk Factors for Development and Progression of Scoliosis After Pediatric Cardiothoracic Operations.

Background: The purpose of this study was to determine the incidence and risk factors for the development and rate of progression of scoliosis and moderate/severe scoliosis in patients undergoing cardiothoracic operations (CTOs).

Methods: Included were patients aged younger than 12 years who underwent CTOs in 1995 to 2006 with a preoperative chest roentgenogram (CRG) and a CRG at least 8 years after CTOs. Scoliosis and moderate/severe scoliosis were defined as a Cobb angle of 10 degrees or more and an angle of 25 degrees or more or the need for surgical intervention, respectively.

Derivation and maturation of synthetic and contractile vascular smooth muscle cells from human pluripotent stem cells.

Aims: Embryonic vascular smooth muscle cells (vSMCs) have a synthetic phenotype; in adults, they commit to the mature contractile phenotype. Research shows that human pluripotent stem cells (hPSCs) differentiate into vSMCs, but nobody has yet documented their maturation into the synthetic or contractile phenotypes. This study sought to control the fate decisions of hPSC derivatives to guide their maturation towards a desired phenotype.

The G-protein coupled receptor, GPR84 regulates IL-4 production by T lymphocytes in response to CD3 crosslinking.

The orphan G-protein coupled receptor, GPR84 is highly expressed in the bone marrow, and in splenic T cells and B cells. In this study, GPR84-deficient mice were generated to understand the biological function of this orphan receptor. The proliferation of T and B cells in response to various mitogens was normal in GPR84-deficient mice.

CCR8 is not essential for the development of inflammation in a mouse model of allergic airway disease.

Chemokine receptors play an important role in the trafficking of various immune cell types to sites of inflammation. Several chemokine receptors are differentially expressed in Th1 and Th2 effector populations. Th2 cells selectively express CCR3, CCR4, and CCR8, which could direct their trafficking to sites of allergic inflammation.
