Using Discrete Event Simulation to Design and Assess an AI-aided Workflow for Same-day Diagnostic Testing of Women Undergoing Breast Screening.

The process of patients waiting for diagnostic examinations after an abnormal screening mammogram is inefficient and anxiety-inducing. Artificial intelligence (AI)-aided interpretation of screening mammography could reduce the number of recalls after screening. We proposed a same-day diagnostic workup to alleviate patient anxiety by employing an AI-aided interpretation to reduce unnecessary diagnostic testing after an abnormal screening mammogram.

Myocardial tissue expression of mRNA and preoperative neutrophil-lymphocyte ratio in children undergoing congenital heart surgery.

Background: The neutrophil-lymphocyte ratio (NLR) is an easily accessible and inexpensive biomarker that has been shown to predict morbidity and mortality in congenital cardiac surgery. However, its regulatory mechanism remains unclear. This study aims to compare and correlate the tumor necrosis factor alpha (TNF-α), interleukin (IL)-1β, IL-6, and IL-10 messenger RNAs (mRNAs) with the NLR in patients with tetralogy of Fallot (ToF) and ventricular septal defect (VSD).

Submitral aneurysm correction with mitral valve repair: a case report.

Submitral aneurysm is a rare type of non-ischaemic ventricular aneurysm. We describe the case of a 26-year-old woman with progressive dyspnoea for approximately 1 year who was diagnosed with a ruptured submitral aneurysm in the left atrium with severe regurgitation. The patient underwent aneurysm correction and mitral valve repair, and post-operative echocardiography showed no residual abnormalities.

Building School-Academic Partnerships to Implement COVID-19 Testing in Underserved Populations.

Objective: In April 2021, the US government made substantial investments in students' safe return to school by providing resources for school-based coronavirus disease 2019 (COVID-19) mitigation strategies, including COVID-19 diagnostic testing. However, testing uptake and access among vulnerable children and children with medical complexities remained unclear.

Methods: The Rapid Acceleration of Diagnostics Underserved Populations program was established by the National Institutes of Health to implement and evaluate COVID-19 testing programs in underserved populations.

Implementation of ESC QI Initiative in Neonatal Unit Setting and Adaptation During the Pandemic.

Objectives: To improve outcomes in infants with neonatal opioid withdrawal syndrome (NOWS) admitted to NICU by implementing a quality improvement (QI) initiative incorporating "eat, sleep, console" (ESC) as a withdrawal evaluation tool and promotion of nonpharmacological interventions. Secondarily, we evaluated the impact of the coronavirus disease 2019 pandemic on QI initiative and outcomes.

Methods: We included infants born ≥ 36 weeks gestation and admitted to NICU with a primary diagnosis of NOWS between December 2017 and February 2021.

A Green Method for the Determination of Cadmium in Natural Waters Based on Multi-Fibre Supported Liquid Membranes.

Supported liquid membranes have been used to implement a hollow fibre liquid-phase microextraction (HF-LPME) method for the preconcentration of Cd(II) in natural waters as a sample preparation step for its determination by high-resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS-GFAAS). This system was designed to use four hollow fibres simultaneously with the same sample, thus improving the simplicity, speed and reproducibility of the results. The organic liquid membrane bis-(2,4,4-trimethylpentyl) phosphinic acid (Cyanex 272) dissolved in dihexylether (DHE) was immobilised into the pores of the walls of polypropylene hollow fibres.

Timely access to primary care in New Brunswick: Variability across health regions.

Objective: To examine the factors that influence variation in timely access to primary care across the different health regions in New Brunswick.

Design: Descriptive and comparative study of organizational practices in primary care practices based on speed of access. Data were collected from December 2019 to March 2020 using semistructured interviews conducted by telephone, in person, or online, according to participants' preferences.

Modeling COVID-19 infection dynamics and mitigation strategies for in-person K-6 instruction.

Background: U.S. school closures due to the coronavirus disease 2019 (COVID-19) pandemic led to extended periods of remote learning and social and economic impact on families.

Evaluation of right ventricle systolic function after tetralogy of Fallot repair: A systematic review comparing cardiac magnetic resonance and global longitudinal strain.

Background: Most patients who undergo tetralogy of Fallot (TOF) repair experience late right ventricle (RV) dysfunction due to pulmonary valve regurgitation (PVR). Cardiac magnetic resonance (CMR) is the gold standard method for evaluating RV during follow-up. Global longitudinal strain (GLS) has been introduced as a novel method for the assessment of RV dysfunction.

Giant left myxoma with mitral valve obstruction.

We present a case of a patient admitted with acute pulmonary edema. An echocardiogram showed a giant myxoma of the left atrium causing mitral valve obstruction. The patient underwent urgent cardiac surgery for tumor resection.

Feasibility of Implementing a Modified SENSE Program to Increase Positive Sensory Experiences for Preterm Infants in the Neonatal Intensive Care Unit (NICU): A Pilot Study.

Aims: To evaluate the feasibility of implementing the Supporting and Enhancing NICU Sensory Experiences (SENSE) program with adaptations to increase positive sensory exposure for infants born preterm, support neonatal neurodevelopment, and decrease parent stress.

Methods: Eight infants born between 28 and 33 weeks were recruited within one week of birth. Parents, trained in the program, delivered the SENSE protocol.

Nuclear RIPK1 promotes chromatin remodeling to mediate inflammatory response.

RIPK1 is a master regulator of multiple cell death pathways, including apoptosis and necroptosis, and inflammation. Importantly, activation of RIPK1 has also been shown to promote the transcriptional induction of proinflammatory cytokines in cells undergoing necroptosis, in animal models of amyotrophic lateral sclerosis (ALS) and Alzheimer's disease (AD), and in human ALS and AD. Rare human genetic carriers of non-cleavable RIPK1 variants (D324V and D324H) exhibit distinct symptoms of recurrent fevers and increased transcription of proinflammatory cytokines.

School Masking Policies and Secondary SARS-CoV-2 Transmission.

Objectives: Throughout the COVID-19 pandemic, masking has been a widely used mitigation practice in kindergarten through 12th grade (K-12) school districts to limit within-school transmission. Prior studies attempting to quantify the impact of masking have assessed total cases within schools; however, the metric that more optimally defines effectiveness of mitigation practices is within-school transmission, or secondary cases. We estimated the impact of various masking practices on secondary transmission in a cohort of K-12 schools.

Neutrophil-Lymphocyte Ratio in Congenital Heart Surgery: What Is Known and What Is New?

Operative mortality after repair of congenital heart disease has improved dramatically over the past few decades. Nevertheless, there is always room for the additional mitigation of complications and mortality. Being able to anticipate adverse outcomes is clearly important, especially when using low-cost and easily accessible resources.

Selective Targeting of the Novel CK-10 Nanoparticles to the MDA-MB-231 Breast Cancer Cells.

The main objective of this project was to formulate novel decorated amphiphilic PLGA nanoparticles aiming for the selective delivery of the novel peptide (CK-10) to the cancerous/tumor tissue. Novel modified microfluidic techniques were used to formulate the nanoparticles. This technique was modified by using of Nano Assemblr associated with salting out of the organic solvent using KHPO.
