Comparison of Taxonomic Resolutions of Various Typing Methods for and Species Isolated from Landfill Leachate.

Anaerobic bacteria and methanogenic archaea at municipal landfill dumping sites play a vital role in the landfill ecology, waste degradation, global warming and climate change. Although landfill works as a cheap way of solid waste management, unmanaged landfill plays a significant role in spreading pollutants and pathogens in natural ecosystems. The genera and are important groups of anaerobic microbes from a public and environmental health perspective.

The impact of diabetes mellitus on the outcomes of revascularization for chronic limb-threatening ischemia in the BEST-CLI trial.

Objective: Several observational studies have demonstrated an association between diabetes mellitus (DM) and above-ankle amputation after lower extremity revascularization (LER). However, data from prospective randomized trials is lacking. This analysis compares the outcomes of patients with and without DM enrolled in the Best Endovascular vs Best Surgical Therapy in patients with Chronic Limb-Threatening Ischemia (BEST-CLI) trial.

Outcomes of a Novel Single-Branched Aortic Stent Graft for Treatment of Type B Aortic Dissection.

Background: Intervention on type B dissection frequently requires landing the proximal edge of the stent graft between the left common carotid artery and left subclavian artery (LSA). The GORE TAG thoracic branch endoprosthesis is a technology that allows LSA preservation with a single internal branch.

Methods: This study was a prospective nonrandomized single-arm clinical trial of patients with type B aortic dissection who were treated with the single-branched device.

The impact of revascularization strategy on clinical failure, hemodynamic failure, and chronic limb-threatening ischemia symptoms in the BEST-CLI Trial.

Objective: Sustained clinical and hemodynamic benefit after revascularization for chronic limb-threatening ischemia (CLTI) is needed to resolve symptoms and prevent limb loss. We sought to compare rates of clinical and hemodynamic failure as well as resolution of initial and prevention of recurrent CLTI after endovascular (ENDO) vs bypass (OPEN) revascularization in the Best-Endovascular-versus-best-Surgical-Therapy-in-patients-with-CLTI (BEST-CLI) trial.

Methods: As planned secondary analyses of the BEST-CLI trial, we examined the rates of (1) clinical failure (a composite of all-cause death, above-ankle amputation, major reintervention, and degradation of WIfI stage); (2) hemodynamic failure (a composite of above-ankle amputation, major and minor reintervention to maintain index limb patency, failure to an initial increase or a subsequent decrease in ankle brachial index of 0.

Isolation and characterization of rabies monoclonal antibody charge variants.

Current postexposure prophylaxis of rabies includes vaccines, human rabies immunoglobulin (RIG), equine RIG, and recombinant monoclonal antibodies (mAb). In the manufacturing of rabies recombinant mAb, charge variants are the most common source of heterogeneity. Charge variants of rabies mAb were isolated by salt gradient cation exchange chromatography (CEX) to separate acidic and basic and main charge variants.

Quality of Life in Patients With Chronic Limb-Threatening Ischemia Treated With Revascularization.

Background: In the BEST-CLI trial (Best Endovascular Versus Best Surgical Therapy for Patients With Chronic Limb-Threatening Ischemia), a prespecified secondary objective was to assess the effects of revascularization strategy on health-related quality of life (HRQoL).

Methods: Patients with chronic limb-threatening ischemia were randomized to surgical bypass (Bypass) or endovascular intervention (Endo) in 2 parallel trials. Cohort 1 included patients with single-segment great saphenous vein; cohort 2 included those lacking suitable single-segment great saphenous vein.

No Evidence That Analgesic Use after COVID-19 Vaccination Negatively Impacts Antibody Responses.

Uptake of mRNA vaccines, especially booster immunizations, against COVID-19 has been lower than hoped, perhaps in part due to their reactogenicity. Analgesics might alleviate symptoms associated with vaccination, but they might also impact immune responses. We semiquantitatively measured Ab responses following COVID-19 vaccination in 2354 human participants surveyed about analgesic use after vaccination.

Implications of IR Being a Primary Specialty on the Professional Organizational Relationship between Interventional and Diagnostic Radiology.

The recent awarding of primary specialty status to interventional radiology (IR) invites a re-examination of the long-standing relationship between IR and diagnostic radiology (DR). In this new era, it is important to evaluate how the organizations that represent these 2 specialties can best contribute to strengthening a growth in collaborations and partnerships that will benefit their members and patients. Areas of organizational focus with the potential to enhance the future for both groups include combining efforts directed toward advocacy and government relations, developing practice models to create successful IR and DR working relationships, and providing more data to demonstrate the value of IR above and beyond the work relative value units and professional revenues that IR generates.

Determinants of B cell responses to drifted epitopes in post-vaccination SARS-CoV-2 infections.

Vaccine-induced immunity may impact subsequent responses to drifted epitopes in SARS-CoV-2 variants, but this has been difficult to quantify due to the challenges in recruiting unvaccinated control groups whose first exposure to SARS-CoV-2 is a primary infection. Through local, statewide, and national SARS-CoV-2 testing programs, we were able to recruit cohorts of individuals who had recovered from either primary or post-vaccination infections by either the Delta or Omicron BA.1 variants.

Cardiac Pulsatile Helical Deformation of the Thoracic Aorta Before and After Thoracic Endovascular Aortic Repair of Type B Dissections.

Purpose: Type B aortic dissections propagate with either achiral (nonspiraling) or right-handed chiral (spiraling) morphology, have mobile dissection flaps, and are often treated with thoracic endovascular aortic repair (TEVAR). We aim to quantify cardiac-induced helical deformation of the true lumen of type B aortic dissections before and after TEVAR.

Material And Methods: Retrospective cardiac-gated computed tomography (CT) images before and after TEVAR of type B aortic dissections were used to construct systolic and diastolic 3-dimensional (3D) surface models, including true lumen, whole lumen (true+false lumens), and branch vessels.

Conformational dynamicity in a copper(II) coordination complex.

The geometries of copper coordination complexes are intricately related to their electron transfer capabilities, but the role of dynamics in these processes are not fully understood. We have previously reported CuCl(dpa), a complex exhibiting conformational fluxionality in its Cu state and rigidity upon oxidation to Cu. Here, we report the synthesis and characterization of [CuCl(dpa)], a complex exhibiting relative rigidity in its Cu state and structural dynamics upon oxidation to Cu.

Surgery or Endovascular Therapy for Chronic Limb-Threatening Ischemia.

Background: Patients with chronic limb-threatening ischemia (CLTI) require revascularization to improve limb perfusion and thereby limit the risk of amputation. It is uncertain whether an initial strategy of endovascular therapy or surgical revascularization for CLTI is superior for improving limb outcomes.

Methods: In this international, randomized trial, we enrolled 1830 patients with CLTI and infrainguinal peripheral artery disease in two parallel-cohort trials.

First peripheral drug-eluting stent clinical results from China: 1-year outcomes of the Zilver PTX China study.

Purpose: The benefit of using the Zilver PTX drug-eluting stent (DES) in superficial femoral artery (SFA) lesions has been demonstrated in multiple clinical studies. This prospective, multicenter study evaluated the 1-year safety and effectiveness of the DES for the treatment of femoropopliteal lesions in a Chinese patient population.

Methods: Patients with a single or restenotic SFA lesion ≤140 mm and a Rutherford classification of 2 to 4 were treated with the DES.

Outcomes of embolization procedures for type II endoleaks following endovascular abdominal aortic repair.

Objective: The objective of this study was to investigate the mid-term outcomes of embolization procedures for type II endoleak after endovascular abdominal aortic repair, and clarify the risk factors for aneurysm enlargement after embolization procedures.

Methods: This was a retrospective multicenter registry study enrolling patients who underwent embolization procedures for type II endoleaks after EVAR from January 2012 to December 2018 at 19 Japanese centers. The primary end point was the rate of freedom from aneurysm enlargement, more than 5 mm in the aortic maximum diameter, after an embolization procedure.

A culture-based and culture-independent approach to the study of landfill leachate bacterial and archaeal communities.

The landfill is a convenient and affordable method of municipal solid waste (MSW) management. Landfill leachate contains a heavy load of pollutants and pathogens. Discharge of untreated leachate is the leading cause of surface and groundwater contamination and a threat to public and environmental health.

Midterm Outcomes of Endovascular Repair of Aortic Arch Aneurysms with the Gore Thoracic Branch Endoprosthesis.

Objective: Aortic aneurysms involving aortic arch vessels are anatomically unsuitable for standard thoracic endovascular repair (TEVAR) without cervical debranching of the arch vessels. Three year outcomes of a single branched thoracic endograft following previous publication of peri-operative and one year outcomes are reported.

Methods: This was a multicentre feasibility trial of the GORE TAG Thoracic Branch Endoprosthesis (TBE), a thoracic endovascular graft incorporating a single retrograde branch for aortic arch vessel perfusion.

Five-year results of the STABLE II study for the endovascular treatment of complicated, acute type B aortic dissection with a composite device design.

Objective: To provide the 5-year outcomes of the use of a composite device (proximal covered stent graft + distal bare stent) for endovascular repair of patients with acute, type B aortic dissection complicated by aortic rupture and/or malperfusion.

Methods: Study of Thoracic Aortic Type B Dissection Using Endoluminal Repair (STABLE) II was a prospective, multicenter study of the Zenith Dissection Endovascular System (William Cook Europe). Patients were enrolled between August 2012 and January 2015 at sites in the United States and Japan.

Outcomes of endovascular repair of aortic aneurysms with the GORE thoracic branch endoprosthesis for left subclavian artery preservation.

Objective: Thoracic endovascular aortic repair has emerged as the dominant paradigm for treatment of patients with descending thoracic aortic aneurysms. For aneurysms involving the aortic arch in the region of the left subclavian artery (LSA), branch vessel preservation to maintain blood flow to the LSA is recommended. Branched aortic endografts are an alternative to surgical revascularization of the LSA.

Immune responses to two and three doses of the BNT162b2 mRNA vaccine in adults with solid tumors.

Vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have shown high efficacy, but immunocompromised participants were excluded from controlled clinical trials. In this study, we compared immune responses to the BNT162b2 mRNA Coronavirus Disease 2019 vaccine in patients with solid tumors (n = 53) who were on active cytotoxic anti-cancer therapy to a control cohort of participants without cancer (n = 50). Neutralizing antibodies were detected in 67% of patients with cancer after the first immunization, followed by a threefold increase in median titers after the second dose.
