Atherosclerosis increases adventitial pressure and limits solute transport via fluid-balance mechanisms.

The adventitia of blood vessels is their structural interface with surrounding tissues and may also contribute importantly to atherogenesis. Adventitial vasa vasorum and lymphatic vessels provide sources and sinks of interstitial fluid and solutes and remodel in disease. We constructed a mathematical model to investigate how soluble disease mediators, including lipoproteins and cytokines, are transported through the artery wall in healthy and atherosclerotic conditions.

A Cross-Sectional Analysis of EMT Certification Rates among Navy Hospital Corpsmen in the INDO-PACIFIC.

Introduction: Until 2017, the United States Navy (USN) incorporated Emergency Medical Technician (EMT) curriculum into Basic Medical Technician Corpsman (BMTC) training program. At overseas USN and Marine Corps installations, USN hospitals and clinics must train and certify EMTs to support the Emergency Medical System (EMS) mission. The primary aim of this study is to identify the impact of removing NREMT curriculum from BMTC on NREMT exam pass rates of students stationed in the Indo-Pacific (INDOPAC) region.

Molecular docking, molecular dynamics simulations and binding free energy studies of interactions between Mycobacterium tuberculosis Pks13, PknG and bioactive constituents of extremophilic bacteria.

Mycobacterial pathogens present a significant challenge to disease control efforts globally due to their inherent resistance to multiple antibiotics. The rise of drug-resistant strains of Mycobacterium tuberculosis has prompted an urgent need for innovative therapeutic solutions. One promising way to discover new tuberculosis drugs is by utilizing natural products from the vast biochemical space.

Transcarotid versus transaxillary access for transcatheter aortic valve replacement with a self-expanding valve: A propensity-matched analysis.

Unlabelled: Transaxillary access has been the most frequently used nonfemoral access route for transcatheter aortic valve replacement (TAVR) with a self-expanding valve. Use of transcarotid TAVR is increasing; however, comparative data on these methods are limited. We compared outcomes following transcarotid or transaxillary TAVR with a self-expanding, supra-annular valve.

Rare disease variant curation from literature: assessing gaps with creatine transport deficiency in focus.

Background: Approximately 4-8% of the world suffers from a rare disease. Rare diseases are often difficult to diagnose, and many do not have approved therapies. Genetic sequencing has the potential to shorten the current diagnostic process, increase mechanistic understanding, and facilitate research on therapeutic approaches but is limited by the difficulty of novel variant pathogenicity interpretation and the communication of known causative variants.

Tandem LC-MS Identification of Antitubercular Compounds in Zones of Growth Inhibition Produced by South African Filamentous Actinobacteria.

Novel antitubercular compounds are urgently needed to combat drug-resistant (Mtb). Filamentous actinobacteria have historically been an excellent source of antitubercular drugs. Despite this, drug discovery from these microorganisms has fallen out of favour due to the continual rediscovery of known compounds.

The evaluation of ADME and pharmacokinetic properties of decoquinate derivatives for the treatment of malaria.

The emergence of () parasite strains tolerant of the artemisinin component and resistant to the other drug component in artemisinin combination therapies (ACTs) used for treatment now markedly complicates malaria control. Thus, development of new combination therapies are urgently required. For the non-artemisinin component, the quinolone ester decoquinate (DQ) that possesses potent activities against blood stage and acts on a distinct target, namely the cytochrome complex, was first considered.

Generation of stable advective-diffusive chemokine gradients in a three-dimensional hydrogel.

Physiologic chemoattractant gradients are shaped by diffusion, advection, binding to an extracellular matrix, and removal by cells. Previous tools for studying these gradients and the cellular migratory response have required cells to be constrained to a 2D substrate or embedded in a gel devoid of fluid flow. Cell migration in fluid flow has been quantified in the absence of chemoattractant gradients and shown to be responsive to them, but there is a need for tools to investigate the synergistic, or antagonistic, effects of gradients and flow.

A Novel Ventilator Design for COVID-19 and Resource-Limited Settings.

There has existed a severe ventilator deficit in much of the world for many years, due in part to the high cost and complexity of traditional ICU ventilators. This was highlighted and exacerbated by the emergence of the COVID-19 pandemic, during which the increase in ventilator production rapidly overran the global supply chains for components. In response, we propose a new approach to ventilator design that meets the performance requirements for COVID-19 patients, while using components that minimise interference with the existing ventilator supply chains.

Discovery of Novel Cyclic Ethers with Synergistic Antiplasmodial Activity in Combination with Valinomycin.

With drug resistance threatening our first line antimalarial treatments, novel chemotherapeutics need to be developed. Ionophores have garnered interest as novel antimalarials due to their theorized ability to target unique systems found in the -infected erythrocyte. In this study, during the bioassay-guided fractionation of the crude extract of strain PR3, a group of cyclodepsipeptides, including valinomycin, and a novel class of cyclic ethers were identified and elucidated.

The Critical Importance of Spatial and Temporal Scales in Designing and Interpreting Immune Cell Migration Assays.

Intravital microscopy and other direct-imaging techniques have allowed for a characterisation of leukocyte migration that has revolutionised the field of immunology, resulting in an unprecedented understanding of the mechanisms of immune response and adaptive immunity. However, there is an assumption within the field that modern imaging techniques permit imaging parameters where the resulting cell track accurately captures a cell's motion. This notion is almost entirely untested, and the relationship between what could be observed at a given scale and the underlying cell behaviour is undefined.

Toward New Transmission-Blocking Combination Therapies: Pharmacokinetics of 10-Amino-Artemisinins and 11-Aza-Artemisinin and Comparison with Dihydroartemisinin and Artemether.

As artemisinin combination therapies (ACTs) are compromised by resistance, we are evaluating triple combination therapies (TACTs) comprising an amino-artemisinin, a redox drug, and a third drug with a different mode of action. Thus, here we briefly review efficacy data on artemisone, artemiside, other amino-artemisinins, and 11-aza-artemisinin and conduct absorption, distribution, and metabolism and excretion (ADME) profiling and pharmacokinetic (PK) profiling via intravenous (i.v.

Referral for Imaging in Physical Therapist Practice: Key Recommendations for Successful Implementation.

In recent years, the use of diagnostic imaging in physical therapist practice in the United States has gained considerable interest. In several countries around the world and in the US military, patient direct referral for diagnostic imaging has been considered normative practice for decades. US physical therapy program accreditation standards now stipulate that diagnostic imaging content must be included in physical therapist educational curricula.

Wearable Technology May Assist in Retraining Foot Strike Patterns in Previously Injured Military Service Members: A Prospective Case Series.

A rearfoot strike (RFS) pattern with increased average vertical loading rates (AVLR) while running has been associated with injury. This study evaluated the ability of an instrumented sock, which provides real-time foot strike and cadence audio biofeedback, to transition previously injured military service members from a RFS to a non-rearfoot strike (NRFS) running pattern. Nineteen RFS runners (10 males, 9 females) were instructed to wear the instrumented socks to facilitate a change in foot strike while completing an independent walk-to-run progression and lower extremity exercise program.

Comparison of chest X-ray interpretation by Emergency Department clinicians and radiologists in suspected COVID-19 infection: a retrospective cohort study.

Objectives: We describe the inter-rater agreement between Emergency Department (ED) clinicians and reporting radiologists in the interpretation of chest X-rays (CXRs) in patients presenting to ED with suspected COVID-19.

Methods: We undertook a retrospective cohort study of patients with suspected COVID-19. We compared ED clinicians' and radiologists' interpretation of the CXRs according to British Society of Thoracic Imaging (BSTI) guidelines, using the area under the receiver operator curve (ROC area).

Rise of the Robots: Is Artificial Intelligence a Friend or Foe to Nursing Practice?

Much like other aspects of health care, nursing has become increasingly saturated with technology over the past several decades. Existing technology has advanced nursing in many ways and contributed to patient safety but at the cost of decreasing nurse-patient interaction. As health care technology progresses to the inclusion of artificial intelligence (AI), the future impact on nursing and direct patient care remains largely unknown, unexplored, and difficult to predict.

Post-intravitreal injection endophthalmitis secondary to Turicella otitidis: a case report.

Background: Endophthalmitis is a rare but potentially devastating complication of intravitreal injection. The causative organism plays an important role in prognosis following endophthalmitis. Here we present the first reported case of Turicella otitidis endophthalmitis, which is notable for a delayed presentation.

Preclinical Activity of HER2-Selective Tyrosine Kinase Inhibitor Tucatinib as a Single Agent or in Combination with Trastuzumab or Docetaxel in Solid Tumor Models.

HER2 is a transmembrane tyrosine kinase receptor that mediates cell growth, differentiation, and survival. HER2 is overexpressed in approximately 20% of breast cancers and in subsets of gastric, colorectal, and esophageal cancers. Both antibody and small-molecule drugs that target HER2 and block its tyrosine kinase activity are effective in treating HER2-driven cancers.

An Integrated Pipeline for Combining Data and Mathematical Models Using a Bayesian Parameter Inference Approach to Characterize Spatio-temporal Chemokine Gradient Formation.

All protective and pathogenic immune and inflammatory responses rely heavily on leukocyte migration and localization. Chemokines are secreted chemoattractants that orchestrate the positioning and migration of leukocytes through concentration gradients. The mechanisms underlying chemokine gradient establishment and control include physical as well as biological phenomena.

Comparison of Outcomes After Transcatheter vs Surgical Aortic Valve Replacement Among Patients at Intermediate Operative Risk With a History of Coronary Artery Bypass Graft Surgery: A Post Hoc Analysis of the SURTAVI Randomized Clinical Trial.

Importance: Surgical aortic valve replacement (SAVR) has increased risk for patients with aortic stenosis (AS) and a history of coronary artery bypass graft (CABG) surgery. Transcatheter aortic valve replacement (TAVR) may be an alternative.

Objective: To compare TAVR with SAVR outcomes in patients at intermediate operative risk with prior CABG surgery.

A Cluster of Cyclic Esotropia: White Matter Changes on MRI and Surgical Outcomes.

Purpose: To report a series of patients with cyclic esotropia, their surgical outcomes, and incidental findings.

Methods: The medical records of five patients with cyclic esotropia presenting over 17 months were reviewed. Age at onset, ocular and motility examinations, brain magnetic resonance imaging (MRI), acetylcholine receptor antibodies, thyroid hormone levels and antibodies, calendars documenting phases, surgical treatments, postoperative alignment, and fusion were documented.

Functional Heatmap: an automated and interactive pattern recognition tool to integrate time with multi-omics assays.

Background: Life science research is moving quickly towards large-scale experimental designs that are comprised of multiple tissues, time points, and samples. Omic time-series experiments offer answers to three big questions: what collective patterns do most analytes follow, which analytes follow an identical pattern or synchronize across multiple cohorts, and how do biological functions evolve over time. Existing tools fall short of robustly answering and visualizing all three questions in a unified interface.
