Radiotracers for in situ infection imaging: Experimental considerations for in vitro microbial uptake of gallium-68-labeled siderophores.

In vitro screening of gallium-68(Ga)-siderophores in pathogens relevant to infections is valuable for determining species specificity, their effect on cell viability, and potential clinical applications. As the recognition and internalization of siderophores relies on the presence of receptor- and/or siderophore-binding proteins, the level of uptake can vary between species. Here, we report in vitro uptake validation in Escherichia coli with its native siderophore, enterobactin (ENT) ([Ga]Ga-ENT), considering different experimental factors.

[Ga]Ga-Schizokinen, a Potential Radiotracer for Selective Bacterial Infection Imaging.

Gallium-68-labeled siderophores as radiotracers have gained interest for the development of infection-specific imaging diagnostics. Here, we report radiolabeling, screening, and pharmacokinetics (PK) of gallium-68-labeled schizokinen ([Ga]Ga-SKN) as a new potential radiotracer for imaging bacterial infections. We radiolabeled SKN with ≥95% radiochemical purity.

Supporting Employment Consultants to Implement Supported and Customized Employment.

Implementing supported and customized employment in all their components is essential for supporting job seekers with disabilities to achieve their career goals. We asked 42 employment consultants in nine employment programs to respond daily to three quick questions about their employment support activities, for 6 months. Through monthly coaching, we helped the managers of these organizations engage their teams of employment consultants to interpret the data, reflect, set goals, and take action for quality improvement.

HTATIP2 regulates arteriogenic activity in monocytes from patients with limb ischemia.

Use of autologous cells isolated from elderly patients with multiple comorbidities may account for the modest efficacy of cell therapy in patients with chronic limb threatening ischemia (CLTI). We aimed to determine whether proarteriogenic monocyte/macrophages (Mo/MΦs) from patients with CLTI were functionally impaired and to demonstrate the mechanisms related to any impairment. Proarteriogenic Mo/MΦs isolated from patients with CLTI were found to have an impaired capacity to promote neovascularization in vitro and in vivo compared with those isolated from healthy controls.

Mechanical aortic valve may no longer be a contraindication to inner branch aortic arch endografts.

Objectives: The presence of a mechanical aortic valve has been a contraindication to the use of an arch branch aortic endograft due to the risk of damaging the valve, resulting in acute aortic regurgitation, or a trapped endograft.

Methods: We present a 67-year-old woman, with a background of Marfan's syndrome and a previous Bentall's procedure, who presented with a symptomatic enlarging aortic arch and descending thoracic aortic aneurysm, with a type 1A endoleak.

Results: Using an inner branch arch endograft (Cook Medical, Bloomington, Indiana), the nose cone of the delivery system was passed laterally through the semi-circular aperture of the mechanical aortic valve to facilitate deployment just distal to the coronary buttons.

Radiometal chelators for infection diagnostics.

Infection of native tissues or implanted devices is common, but clinical diagnosis is frequently difficult and currently available noninvasive tests perform poorly. Immunocompromised individuals (for example transplant recipients, or those with cancer) are at increased risk. No imaging test in clinical use can specifically identify infection, or accurately differentiate bacterial from fungal infections.

Carbon dioxide flushing versus saline flushing of thoracic aortic stents (INTERCEPTevar): protocol for a multicentre pilot randomised controlled trial.

Introduction: Thoracic endovascular aortic repair (TEVAR) carries a 3%-6.1% stroke risk, including risk of 'silent' cerebral infarction (SCI). Stent-grafts are manufactured in room air and retain air.

Management of secondary aorto-enteric fistulae: a multi-centre study.

Background: Secondary aorto-enteric fistulae (SAEF) are a rare, complex and life-threatening complication following aortic repair. Traditional treatment strategy has been with open aortic repair (OAR), with emergence of endovascular repair (EVAR) as a potentially viable initial treatment option. Controversy exists over optimal immediate and long-term management.

Novel modification of a branched arch endograft with a retrograde left common carotid branch for acute pseudoaneurysm post type A repair.

Objective: Pseudoaneurysm formation post type A aortic dissection repair is rare. Revision surgical repair is challenging, with a risk of death from haemorrhage.

Methods: We present a 56-year-old man who presented with a rapidly enlarging distal ascending aortic anastomotic pseudoaneurysm following a recent ascending and hemiarch replacement for acute type A aortic dissection.

The Benefits of Active, Person-Centered Job Placement: Results From Service Providers Undergoing Organizational Transformation Away From Sheltered Employment.

Recent national and state-level policy changes have created an imperative for service providers to transform from sheltered work to competitive integrated employment. The current study sought to understand the impact of participation in a 1-year, comprehensive technical assistance pilot designed to support service providers to transform away from sheltered workshops towards encouraging competitive integrated employment and delivering job development supports. Findings showed competitive integrated employment is attainable if given the appropriate organizational emphasis and when effective job development practices are implemented to a strategically identified group.

Predictors of percutaneous access-related complications in aortic endovascular procedures: 'real-world' insights and a comparison to open access.

Background: Percutaneous endovascular aneurysm repair (PEVAR) is becoming increasingly popular due to fewer access-related complications, shorter procedural times and length of stay (LOS). Our aim was to explore factors associated with access-related complications and their impact on procedural time and LOS.

Methods: We retrospectively analyzed consecutive aorto-iliac endovascular procedures in a tertiary hub comprising 2 institutions and 18 consultant vascular surgeons and interventional radiologists between 2016-2017.

A systematic review of pharmacologic and cell-based therapies for treatment of lymphedema (2010-2021).

Background: Lymphedema describes the accumulation of interstitial fluid that results from lymphatic failure. Lymphedema can be of primary or secondary origin and has been estimated to affect 200 million people worldwide. Secondary lymphedema is commonly due to damage to the lymphatic vessels after surgical procedures.

Mutations in EPHB4 cause human venous valve aplasia.

Venous valve (VV) failure causes chronic venous insufficiency, but the molecular regulation of valve development is poorly understood. A primary lymphatic anomaly, caused by mutations in the receptor tyrosine kinase EPHB4, was recently described, with these patients also presenting with venous insufficiency. Whether the venous anomalies are the result of an effect on VVs is not known.

"Awake" Spinal Cord Monitoring Under Local Anesthesia and Conscious Sedation in Fenestrated and Branched Endovascular Aortic Repair.

Introduction: Endovascular repair of thoracoabdominal aortic aneurysms carries a risk of spinal cord ischemia, the causes of which remain uncertain. We hypothesized that local anesthesia (LA) with conscious sedation could abrogate the potential suppressive cardiovascular effects of general anesthesia (GA) and facilitate intraoperative monitoring of neurological function. Here, we examine the feasibility of this technique during fenestrated (FEVAR) or branched endovascular aortic repair (BEVAR).
