Bedside monitoring tools and advanced signal processing approaches to monitor critically-ill infants.

Semin Fetal Neonatal Med

November 2024

Institute for Smart, Secure and Connected Systems: ISSACS, Case Western Reserve University, Cleveland, OH, USA. Electronic address:

There is a substantial body of literature that supports neonatal monitoring and signal analysis of the collected data to provide valuable insights for improving patient clinical care and to inform new research studies. This comprehensive monitoring approach extends beyond the collection of conventional vital signs to include the acquisition of continuous waveform data from patient monitors and other bedside medical devices. This paper discusses the necessary infrastructure for waveform retrieval from bedside monitors, and explores options provided by leading healthcare companies, third-party vendors or academic research teams to implement scalable monitoring systems across entire critical care units.

Objective: Syndromic assessment with multiplex polymerase chain reaction (mPCR) testing in patients with acute respiratory illness (ARI) allows for simultaneous identification of multiple possible infectious etiologies. Point-of-care (POC) syndromic assessment can be conducted in a clinical setting, such as an urgent care center (UCC), without requiring certified laboratories. The primary objective of this study was to determine whether POC syndromic assessment improved patient satisfaction for patients seen at an UCC with ARI; secondary objectives included whether syndromic assessment reduced self-isolation time, increased diagnostic confidence, and reduced overall antibiotic utilization.

Purpose: Relaxation correction is crucial for accurately estimating metabolite concentrations measured using in vivo MRS. However, the majority of MRS quantification routines assume that relaxation values remain constant across the lifespan, despite prior evidence of T changes with aging for multiple of the major metabolites. Here, we comprehensively investigate correlations between T and age in a large, multi-site cohort.

Article Synopsis
  • * Researchers used advanced imaging techniques to analyze how different parts of the hippocampus connect with specific cortical pathways during brain development, with the front part linked to the anterior temporal pathway and the back part to the posterior medial pathway.
  • * The study found that as brains develop, there is a shift in connectivity from the back to the front of the hippocampus, emphasizing its role in episodic memory and identifying key regions that influence how the hippocampus integrates into broader brain functions.

Background: Depression is highly prevalent in patients with aortic diseases. While depression has been shown to predispose patients to adverse outcomes after surgery, its impact on postoperative outcomes in Stanford Type A Aortic Dissection (TAAD) has not been established. This study aimed to conduct a population-based examination of the effect of preoperative depression on in-hospital outcomes after TAAD using the National/Nationwide Inpatient Sample (NIS) database, the largest all-layer database in the US.

Background: Carotid endarterectomy (CEA) is an effective treatment for carotid stenosis. Previous studies yielded conflicting findings regarding postoperative outcomes after CEA when comparing those under general and locoregional anesthesia. However, these findings may be influenced by an inherent selection bias, as general anesthesia is frequently selected for more complex CEA.

Advances in antiretroviral therapy (ART) have made it possible for persons with human immunodeficiency virus (HIV) to live a lifespan approaching that of people without HIV, without progressing to AIDS or transmitting HIV to sexual partners or infants. There is, therefore, increasing emphasis on maintaining health throughout the lifespan. To receive optimal medical care and achieve desired outcomes, persons with HIV must be consistently engaged in care and able to access uninterrupted treatment, including ART.

Article Synopsis
  • The study investigates the relationship between dependent functional status (DFS) and 30-day outcomes in patients with ruptured and nonruptured abdominal aortic aneurysm (AAA) undergoing endovascular aneurysm repair (EVAR), highlighting the need for differentiated analysis due to previous study limitations.
  • Utilizing data from the American College of Surgeons database between 2012-2022, the researchers compared outcomes by stratifying patients based on their functional status, with a focus on matching those with DFS and independent functional status (IFS) in nonruptured cases.
  • Results showed that nonruptured patients with DFS had similar 30-day mortality rates as those with IFS, but a higher risk of requiring blood transfusions and longer hospital stays

Electronic address:

Introduction: Sepsis-induced cardiac dysfunction is one of the most serious complications of sepsis. The mitochondrial translocator protein (TSPO), a mitochondrial outer membrane protein, is widely used as a diagnostic marker of inflammation-related diseases and can also lead to the release of inflammatory components. However, whether TSPO has a therapeutic effect on sepsis-induced cardiac dysfunction is unclear.

Background: Multiple clinical trials evaluating therapies for cerebral malaria (CM) have failed to demonstrate improved outcomes. This may derive from inclusion of children at all risk levels, including those at low risk of mortality or neurologic morbidity, limiting power to detect significant differences between intervention arms. One solution is enrichment, enrolling clinical trial participants at higher risk of adverse outcomes.
