A Giant Aneurysm of Vieussens' Arterial Ring With Pulmonary Artery Fistula.

A 79-year-old woman presented with a systolic murmur and dyspnea on exertion. Transthoracic echocardiography and multidetector-row computed tomography revealed a giant aneurysm in an abnormal vessel known as Vieussens' arterial ring (VAR). A pulmonary artery VAR fistula was also observed.

Does Cardiac Function Improvement With Coronary Artery Bypass Grafting Reduce All-Cause Mortality?

Background: The effect of coronary artery bypass grafting (CABG) on cardiac function improvement remains controversial. Furthermore, recent evidence suggests that improvement in cardiac function after CABG does not improve life expectancy. This study aimed to examine whether CABG improved cardiac function and how this improvement influenced all-cause mortality and to compare patient prognosis according to preoperative cardiac function.

Effectiveness of sequential bilateral repetitive transcranial stimulation versus bilateral theta burst stimulation for patients with treatment-resistant depression (BEAT-D): A randomized non-inferiority clinical trial.

Background: Bilateral repetitive transcranial magnetic stimulation (BL-rTMS) over the dorsolateral prefrontal cortex is effective for treatment-resistant depression (TRD). Owing to a shorter treatment time, bilateral theta burst stimulation (BL-TBS) can be more efficient protocol. The non-inferiority of BL-TBS to BL-rTMS was established in late-life TRD; however, this has not been determined in adults of other age groups.

[Initiatives for Rapid Reporting of Antibiotic Resistance Information Using Disk Diffusion for Positive Blood Culture].

Bacteremia can easily become severe, and it is necessary to start appropriate treatment quickly before it progresses to sepsis. In this study, we investigated a method using antibiotic discs to quickly report antibiotic resistance information for bacteremia caused by gramnegative bacilli, such as , which require careful selection of appropriate antibiotics due to their tendency to cause severe illness. In cases of bacteremia caused by ESBL and AmpC-producing bacteria, reports of suspected antibiotic resistance mechanisms were made within a few hours after disk placement, allowing for the rapid modification of antimicrobial therapy, thereby contributing to the treatment.

A multisite observational real-world study on the effectiveness of repetitive transcranial magnetic stimulation therapy for patients with treatment-resistant depression in Japan.

The objective of this study was to reveal the effectiveness of repetitive transcranial magnetic stimulation (rTMS) for Japanese patients with treatment-resistant depression (TRD) in clinical practice, based on real-world data from a nationwide multicenter observational study in Japan. Clinical data of patients with TRD treated with rTMS (NeuroStar TMS treatment system) under public insurance coverage were retrospectively collected from 21 institutes nationwide between June 2019 and December 2023. Depression severity was assessed by the 17-item Hamilton Depression Rating Scale (HAMD-17).

Fast Competitive Swimmers Demonstrate a Diminished Diving Reflex.

Competitive swimmers complete 50-m front crawl swimming without breathing or with a limited number of breaths. Breath holding during exercise can trigger diving reflex including bradycardia and diminished active muscle blood flow, whereas oxygen supply to vital organ such as brain is maintained. We hypothesized that swimmers achieving faster time in 50-m front crawl with limited number of breaths demonstrate a blunted diving reflex of cardiac and active muscle blood flow responses with elevated cerebral perfusion to counteract peripheral and central fatigues.

Diagnostic accuracy and added value of dynamic chest radiography in detecting pulmonary embolism: A retrospective study.

Purpose: This study aimed to assess the diagnostic performance of dynamic chest radiography (DCR) and investigate its added value to chest radiography (CR) in detecting pulmonary embolism (PE).

Methods: Of 775 patients who underwent CR and DCR in our hospital between June 2020 and August 2022, individuals who also underwent contrast-enhanced CT (CECT) of the chest within 72 h were included in this study. PE or non-PE diagnosis was confirmed by CECT and the subsequent clinical course.

Lymphoproliferative Disorder in an Esophageal Cancer Patient Treated with Pembrolizumab.

A 75-year-old man diagnosed with esophageal cancer and lung metastasis received a combination of fluorouracil, cisplatin, and pembrolizumab. During pembrolizumab maintenance therapy, lymphoproliferative lesions at the lips and mouth and multiple lymph node swellings appeared. Histologically, Epstein-Barr virus (EBV)-encoded RNA was positive, and EBV-DNA was detected in the blood.

Role of phosphorylation and vanilloid ligand structure in ligand-dependent differential activations of transient receptor potential vanilloid 1.

Vanilloid analogs, which can activate transient receptor potential vanilloid 1 (TRPV1), have been classified into two types based on susceptibility to forskolin (FSK). Treatment of cells expressing TRPV1 with FSK enhances TRPV1 responses to capsaicin-type ligands while diminishing the responses to eugenol-type ligands. In this study, we determined the effect of FSK on the activation of TRPV1 stimulated with vanilloid ligands, through the influx of Ca2+ in HEK293T cells expressing TRPV1.

Efficacy and safety of intravenous ketamine treatment in Japanese patients with treatment-resistant depression: A double-blind, randomized, placebo-controlled trial.

Aim: Although the antidepressant effect of ketamine on treatment-resistant depression (TRD) has been frequently reported in North American and European countries, evidence is scarce among the Asian population. We aimed to evaluate the efficacy and safety of intravenous ketamine in Japanese patients with TRD.

Methods: In this double-blind randomized placebo-controlled trial, 34 Japanese patients with TRD were randomized to receive either intravenous ketamine (0.

Inorganic sulfides prevent osimertinib-induced mitochondrial dysfunction in human iPS cell-derived cardiomyocytes.

Despite the widespread recognition of the global concern regarding the onset of cardiovascular diseases in a significant number of patients following cancer treatment, definitive strategies for prevention and treatment remain elusive. In this study, we established systems to evaluate the influence of anti-cancer drugs on the quality control of mitochondria, pivotal for energy metabolism, using human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs). Osimertinib, an epidermal growth factor receptor tyrosine kinase inhibitor used for treatment in lung cancer, reportedly increases the risk of cardiovascular disease.

Treatment trends in patients with de novo metastatic prostate cancer in the era of upfront combination therapy.

Objectives: The objective of this study is to assess the trends in treatment selection for patients with de novo metastatic castration-sensitive prostate cancer in the era of upfront combination therapy.

Methods: This multicenter retrospective study included 595 patients treated with either upfront combination therapy (upfront novel hormonal therapies and taxane-based chemotherapy) or vintage therapy (androgen deprivation therapy with or without bicalutamide) between 2016 and 2021. High tumor burden metastatic disease was defined when a patient met the CHAARTED or LATITUDE criteria.

Repeated Omicron exposures redirect SARS-CoV-2-specific memory B cell evolution toward the latest variants.

Immunological imprinting by ancestral SARS-CoV-2 strains is thought to impede the robust induction of Omicron-specific humoral responses by Omicron-based booster vaccines. Here, we analyzed the specificity and neutralization activity of memory B (B) cells after repeated BA.5 exposure in individuals previously imprinted by ancestral strain-based mRNA vaccines.

Neurophysiological profiles of patients with bipolar disorders as probed with transcranial magnetic stimulation: A systematic review.

Aim: Bipolar disorder (BD) has a significant impact on global health, yet its neurophysiological basis remains poorly understood. Conventional treatments have limitations, highlighting the need for a better understanding of the neurophysiology of BD for early diagnosis and novel therapeutic strategies.

Design: Employing a systematic review approach of the PRISMA guidelines, this study assessed the usefulness and validity of transcranial magnetic stimulation (TMS) neurophysiology in patients with BD.

Divergent effects of olfactory receptors on transient receptor potential vanilloid 1 activation by capsaicin and eugenol.

We analyzed the effects of olfactory receptors (ORs) on transient receptor potential vanilloid 1 (TRPV1) activation using HEK293T cells co-expressing TRPV1 and OR51E1. We demonstrate here that the effect of OR51E1 on TRPV1 activation varies depending on the two TRPV1 ligands: capsaicin and eugenol. Notably, both of these ligands are vanilloid analogs.
