Development of absorption spectrophotometry of iron(III) in environmental water and sediments using NEDA and its application to the field.

In this study, we developed a simple method that enables iron(III) in environmental water to be directly determined via spectrophotometry. In water samples, iron(III) formed a yellowish complex with N-1-Naphthylethylenediamine dihydrochloride (NEDA) at pH 2.0-2.

[Successful polatuzumab vedotin and rituximab therapy for post-CAR-T relapse of diffuse large B-cell lymphoma].

Relapse or progressive disease after chimeric antigen receptor T-cell (CAR-T) treatment remains a major issue for poor-risk aggressive large B-cell lymphoma. However, limited data are available on post-CAR-T use of polatuzumab vedotin. Here we describe the case of a patient with diffuse large B-cell lymphoma (DLBCL) who experienced relapse three months after CD19-directed CAR-T therapy with tisagenlecleucel.

Covering the intercostal artery branching of the Adamkiewicz artery during endovascular aortic repair increases the risk of spinal cord ischemia.

Objectives: This study aimed to determine the relationship between covering the intercostal artery branching of the Adamkiewicz artery (ICA-AKA) and spinal cord ischemia (SCI) during thoracic endovascular aortic repair (TEVAR).

Methods: Patients who underwent TEVAR from 2008 to 2022 were enrolled. Stent grafts covered the ICA-AKA in 108 patients (covered AKA group) and stent grafts didn't cover the ICA-AKA in 114 patients (uncovered AKA group).

Surgical outcomes of thoracic endovascular aortic repair for retrograde Stanford type a dissection.

Objectives: The optimal indications and contraindications for thoracic endovascular aortic repair of retrograde Stanford type A acute aortic dissection (R-AAAD) are not well known. The goal of this study was to determine the outcomes of thoracic endovascular aortic repair for R-AAAD at our institution and to discuss optimal indications.

Methods: The medical records of 359 patients admitted to our institution for R-AAAD between December 2016 and December 2022 were reviewed, and 83 patients were finally diagnosed with R-AAAD.

Thoracic endovascular aortic repair with collateral vessels from the femoral artery to Adamkiewicz's artery.

Identification of the Adamkiewicz's artery (AKA) prior to the operation is one of the spinal cord ischaemia preventive measures. A 75-year-old man presented with the rapid expansion of thoracic aortic aneurysm. Collateral vessels from the right common femoral artery to the AKA were observed on preoperative computed tomography angiography.

Phylogenetic Analysis and Characterization of Odorous Compound-Producing Actinomycetes in Sediments in the Sanbe Reservoir, A Drinking Water Reservoir in Japan.

Odor caused by the presence of geosmin and 2-methylisoborneol (2-MIB) in aquatic ecosystems leads to considerable economic loss worldwide. The odorous compounds are primarily produced by cyanobacteria and actinomycetes. While the contribution of odorous compounds-producing cyanobacteria has been thoroughly investigated, the production of geosmin and 2-MIB by actinomycetes in aquatic ecosystems is poorly understood.

Aggressive use of prophylactic cerebrospinal fluid drainage to prevent spinal cord ischemia during thoracic endovascular aortic repair is not supportive.

Objectives: We investigated whether prophylactic preoperative cerebrospinal fluid drainage (CSFD) was effective in preventing spinal cord ischemia (SCI) during thoracic endovascular aortic repair of degenerative descending thoracic aortic aneurysms, excluding dissecting aneurysms.

Methods: We retrospectively reviewed the medical records of patients who underwent thoracic endovascular aortic repair involving proximal landing zones 3 and 4 between 2009 and 2020.

Differences of mid-term outcomes in debranching thoracic endovascular aortic repair between zone 0 and zone 1-2 landing.

Objective: Debranching thoracic endovascular aortic repair (d-TEVAR) for zone 0 landing (Z0-TEVAR) remained challenging in aortic arch aneurysms. This study aimed to compare the mid-term outcomes between Z0-TEVAR and Z1/2-TEVAR to assess the appropriateness of Z0-TEVAR as the first-line therapy for aortic arch aneurysms in high-risk patients.

Methods: Medical records of 200 patients who underwent d-TEVAR from 2007 to 2019 were retrospectively reviewed.

Case report: Vascular graft infection due to Aspergillus species presenting with recurrent vascular occlusion.

Background: An aortic graft implantation is an effective therapeutic method for various aortic diseases. However, it is known that sometimes these implanted grafts can be the foci of infections. Here we report a rare case of graft infection that presented multiple embolisms of aortic branches and peripheral organs.

Novel brain computed tomography perfusion for cerebral malperfusion secondary to acute type A aortic dissection.

Objectives: The management of acute type A aortic dissection with malperfusion syndrome remains challenging. To evaluate preoperative condition, symptoms might be subjective and objective evaluation of cerebral artery has not yet been established. For quantitative evaluation, this study focused on brain computed tomography perfusion (CTP), which has been recommended by several guidelines of acute ischaemic stroke.

Nationwide Analysis of Persistent Type II Endoleak and Late Outcomes of Endovascular Abdominal Aortic Aneurysm Repair in Japan: A Propensity-Matched Analysis.

Background: We reviewed the results of endovascular aneurysm repair in patients from the Japanese Committee for Stentgraft Management registry to determine the significance of persistent type II endoleak (p-T2EL) and the risk of late adverse events, including aneurysm sac enlargement.

Methods: The prospectively captured medical records of 17 099 patients <75 years of age who underwent endovascular aneurysm repair for abdominal aortic aneurysm from 2006 to 2015 were reviewed. Patients were divided into 2 groups (with or without p-T2EL) and compared to examine the correlation between p-T2EL and the occurrence of aneurysm sac enlargement after endovascular aneurysm repair.

Reversible left ventricular dysfunction due to severe stenosis of the elephant trunk graft: A case report.

Acquired coarctation of the aorta (CoA) following total aortic arch replacement (TAR) is a rare complication inducing left ventricular (LV) dysfunction probably due to increased LV afterload and secondary hypertension caused by increased upper body and decreased renal blood flow. We describe a case of a 35-year-old male who developed atypical CoA with severe LV dysfunction with LV ejection fraction of 10%, but without secondary hypertension after TAR using conventional elephant trunk (ET) technique for acute aortic dissection. Computed tomography revealed near-occlusive CoA due to narrowed distal ET.

Methods: A total of 104 patients who underwent surgery for rAAA between 2007 and 2018 were reviewed. Preoperative shock, defined as a shock index (heart rate/blood pressure) exceeding 1.

Measurement Properties of the Canadian Occupational Performance Measure: A Systematic Review.

Importance: The Canadian Occupational Performance Measure (COPM) is widely used in clinical practice and research. However, the measurement properties of the COPM were not reviewed using rigorous systematic methodology.

Objective: To evaluate the measurement properties of the COPM.

Development of second primary small-cell lung cancer within the irradiated field after chemoradiotherapy: a report of two cases.

Two male smokers developed small-cell lung cancer (SCLC) as the second primary malignancy (SPM) in the irradiated field after concurrent chemoradiotherapy for locally advanced cancer, which could also be considered as a radiation-induced tumour. A 70-year-old man received cisplatin and S-1 and irradiation at 60 Gy for lung adenocarcinoma eight years previously and an 81-year-old man cisplatin and 5-fluorouracil and at irradiation 60 Gy for oesophageal cancer five years previously. They sequentially received chemotherapy for SCLC, the effects of which were limited, and a refractory course was noted.

Open anatomical repair for primary coarctation of the aorta in adults.

Objectives: Although endovascular repair has become an alternative treatment for coarctation of the aorta (CoA) in adults, open repair provides concomitant repair of other cardiac complications, including post-stenotic aneurysm, ascending aortic aneurysm, and intracardiac diseases. We evaluated open anatomical repair for CoA repair in adults.

Methods: Eleven patients (6 men, age range 21-63 years) underwent primary CoA repair.
