Introduction: The shock index pediatric adjusted score (SIPA) predicts the need for blood transfusion (BT), hemorrhage control interventions (HCI), morbidity/mortality among older pediatric trauma patients but is less predictive in younger patients. We hypothesize that SIPA will be predictive among older pediatric patients for BT, HCI, mortality, and need for trauma intervention (NFTI), however we aim to further delineate the gap in utilizing SIPA in younger patients.

Methods: Using the ACS NTDB for 2017-2021 we evaluated patients 1-14 years old who were transported by EMS from the scene for definitive care.

Article Synopsis
  • Acquired supracarinal tracheal stenosis is a type of postintubation narrowing of the lower trachea that standard tracheostomy tubes can't bypass.
  • Managing this condition surgically is tricky due to the deep location of the stenosis, requiring close cooperation between the surgical and anaesthesia teams for effective patient care.
  • A successful case of this condition was treated using a transoral Diode laser-assisted approach at a tertiary care center known for handling similar cases.

Schwannomas are benign peripheral nerve sheath tumours with a low risk of malignant transformation. About 25%-40% are in the head and neck region with the posterior third of the tongue being a rather rare site of its growth, and a lesion at this site is understandably difficult to approach and treat. Being benign and encapsulated, surgical excision is in the mainstay of treatment.

Microbial fuel cell (MFC) technology is getting acceptance as an emphatic, sustainable and energy efficient alternative of conventional wastewater treatment strategies. MFCs utilize exoelectrogens as biocatalysts to degrade the complex organic substances present in wastewater with simultaneous power generation. The present study was aimed at investigating the impact of MFC electrode's modification with CeO nanoparticles and polyaniline (PANI) on its performance characteristics.

Introduction: Literature shows failure of the outpatient clinic (OC) pathway after emergency department (ED) ultrasound diagnosis of symptomatic cholelithiasis (SC). We hypothesized SC to be more prevalent on final surgical pathology (FSP) in patients who successfully completed OC pathway.

Methods: This retrospective single-institution chart review compared OC and ED patients with right upper quadrant (RUQ) pain and cholelithiasis whom underwent cholecystectomy.

Article Synopsis
  • Laparoscopic pancreaticoduodenectomy (PD) is gaining popularity, but it has a challenging learning curve that may hinder surgeons moving to new institutions.
  • A study reviewed laparoscopic PD surgeries from two institutions, comparing outcomes and learning curves for the same surgeon at both locations.
  • Results showed that the surgeon achieved the same skill level much faster at the new institution, indicating that specialized surgical techniques can be effectively transferred without losing performance quality.

The tobacco cutworm () is a widespread pest that inflicts severe damage on various crops, including cotton, tobacco, and vegetables, with a particular preference for solanaceous plants. Traditional control methods often rely heavily on synthetic insecticides, leading to adverse effects on the environment, human health, and the development of insecticide resistance. In light of these challenges, this study explores the potential of nanotechnology as an innovative and sustainable approach to combat this notorious pest.

Background: The majority of final surgical pathology (FSP) from both emergency department (ED) and outpatient clinic (OC) patients is chronic cholecystitis. We aimed to differentiate these presentations and identify disparities associated with ED utilization and OC failure.

Methods: Retrospective chart review of single institution ED and OC cholecystectomies for cholelithiasis.

Introduction: Incidence of blunt cerebrovascular injury (BCVI) following hanging in the pediatric population is ill-defined. Current guidelines recommend screening imaging during the initial trauma evaluation. Necessity of screening is questioned given BCVI is considered rare after hanging, especially when asymptomatic.

Methemoglobinemia (MetHb, Fe) is a chronic disease arising from the unequal distribution of oxyhemoglobin (HbFe, OHb) in the blood circulatory system. The oxidation of standard oxyhemoglobin forms methemoglobin, causing cyanosis (skin bluish staining). Methemoglobin cannot bind the pulmonary gaseous ligands such as oxygen (O) and carbon monoxide (CO).

Purpose To develop optoacoustic, spectrally distinct, actively targeted gold nanoparticle-based near-infrared probes (trastuzumab [TRA], TRA-Aurelia-1, and TRA-Aurelia-2) that can be individually identifiable at multispectral optoacoustic tomography (MSOT) of human epidermal growth factor receptor 2 (HER2)-positive breast tumors. Materials and Methods Gold nanoparticle-based near-infrared probes (Aurelia-1 and 2) that are optoacoustically active and spectrally distinct for simultaneous MSOT imaging were synthesized and conjugated to TRA to produce TRA-Aurelia-1 and 2. Freshly resected human HER2-positive ( = 6) and HER2-negative ( = 6) triple-negative breast cancer tumors were treated with TRA-Aurelia-1 and TRA-Aurelia-2 for 2 hours and imaged with MSOT.

Two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is a phytophagous haplodiploid mite and its control is largely based on the use of pesticides. But, the short life cycle and high reproductive rate allow them to develop resistance to many pesticides. To design a strategy for resistance management, a fitness cost study was conducted on different populations of T.

Procalcitonin (PCT) is a biomarker for sepsis, but its utility has not been investigated in necrotizing enterocolitis (NEC). Necrotizing enterocolitis is a devastating multisystem disease of infants that in severe cases requires surgical intervention. We hypothesize that an elevated PCT will be associated with surgical NEC.

Nanoscale surface roughness has conventionally been induced by using complicated approaches; however, the homogeneity of superhydrophobic surface and hazardous pollutants continue to have existing challenges that require a solution. As a prospective solution, a novel bubbled-structured silica nanoparticle (SiO) decorated electrospun polyurethane (PU) nanofibrous membrane (SiO@PU-NFs) was prepared through a synchronized electrospinning and electrospraying process. The SiO@PU-NFs nanofibrous membrane exhibited a nanoscale hierarchical surface roughness, attributed to excellent superhydrophobicity.

Background and purpose Gadolinium-based contrast agents (GBCAs) have been administered clinically since 1988. They are remarkably well tolerated by children and result in dose-dependent tissue deposition, even in patients with normal renal function. No adverse effects of gadolinium deposition in patients with normal renal function have been established.

The rapid growth of population and industrialization have intensified the problem of water pollution globally. To meet the challenge of industrialization, the use of synthetic dyes in the textile industry, dyeing and printing industry, tannery and paint industry, paper and pulp industry, cosmetic and food industry, dye manufacturing industry, and pharmaceutical industry has increased exponentially. Among these industries, the textile industry is prominent for the water pollution due to the hefty consumption of water and discharge of coloring materials in the effluent.
