Survival Outcomes Associated With Radiological Progressive Disease Subtypes in Patients With Atezolizumab and Bevacizumab-Treated HCC.

Background And Aim: To assess the relationship between survival outcomes and subtypes of radiological progressive disease (PD) in patients with hepatocellular carcinoma (HCC) treated with atezolizumab and bevacizumab (Atezo/Bev).

Methods: A total of 462 patients with Atezo/Bev-treated HCC diagnosed with radiological PD during follow-up were enrolled. PD was classified into three categories: progression or emergence of intrahepatic lesions (PD-IH), macroscopic vascular invasion (PD-MVI), and extrahepatic spread lesions (PD-EHS).

Evaluation of Treatment Outcomes Using dNLR and GNRI in Combination Therapy With Atezolizumab and Bevacizumab for Hepatocellular Carcinoma.

Aim: This study aims to investigate the clinical utility of the derived neutrophil-to-lymphocyte ratio (dNLR) and the Geriatric Nutritional Risk Index (GNRI) in predicting treatment outcomes for patients with unresectable hepatocellular carcinoma (HCC) undergoing combination therapy with atezolizumab and bevacizumab (Atez/Bev).

Methods: A retrospective analysis was conducted on 310 patients. The dNLR, NLR, and GNRI were calculated, and their impact on progression-free survival (PFS) and overall survival (OS) was assessed.

High-viscosity dietary fibers modulate gut microbiota and liver metabolism to prevent obesity in high-fat diet-fed mice.

Obesity and metabolic disorders are rising global health concerns, emphasizing the need for effective dietary interventions. High-viscosity dietary fibers such as bacterial cellulose (BC) and guar gum (GG) have unique properties that may complement each other in modulating gut microbiota and metabolic health. This study investigates their effects in high-fat diet-fed mice.

Prognostic Analysis of Pathological Stage I Lung Adenocarcinoma Harboring Major EGFR Mutations.

Background: While Epidermal growth factor receptor (EGFR) mutation-positive lung adenocarcinoma (LUAD) has favorable outcomes with targeted therapy, early-stage prognosis remains influenced by pathological factors and central nervous system (CNS) recurrence. The study aimed to clarify prognostic factors in pathological stage (pStage) I EGFR mutation-positive LUAD.

Methods: Between 2015 and 2018, 2,191 pStage I LUAD cases with known EGFR status (excluding EGFR testing after recurrence) who received anatomical resection were included from multiple institutions in Japan.

Significance of Tumor Microvasculature in the Tumor Microenvironment in Adenocarcinoma with EGFR Common Mutations.

Background: Tumor microvasculature is an important component of the tumor microenvironment (TME), and it has been reported that tumor microvasculature induces TME to become immunosuppressive via vascular endothelial growth factor. However, the significance of this in adenocarcinoma with epidermal growth factor receptor (EGFR) common mutations has not been fully investigated.

Methods: We analyzed 262 patients with adenocarcinoma harboring EGFR common mutations who underwent surgery at Kyushu University Hospital between 2006 and 2021.

Reliable Performance of mALBI Grade-Based Risk Models for Predicting the Prognosis of Patients With Hepatocellular Carcinoma Receiving Atezolizumab Plus Bevacizumab as First-Line Treatment: Comparative Analysis of 13 Risk Models.

Aim: This study aimed to compare the prognostic performance of the risk models for patients with hepatocellular carcinoma (HCC) receiving atezolizumab and bevacizumab (Atez/Bev) as first-line treatment.

Methods: Among 449 patients included in this retrospective multicenter study, we compared the prognostic performance of 13 risk models for the 12-month and 18-month survival status using area under the curve (AUC), net reclassification improvement (NRI), and relative integrated discrimination improvement (IDI) analysis. We also constructed a calibration plot to assess the fitness of each model.

Geriatric nutritional risk index and newly developed scoring system as prognosis prediction for unresectable hepatocellular carcinoma patients treated with lenvatinib.

In the current era of immune therapy, lenvatinib (LEN) continues to be vital for treating unresectable hepatocellular carcinoma (uHCC) patients. This study investigates the importance of nutritional status in the prognosis of uHCC patients receiving LEN and evaluates a new prognostic scoring system that combines the geriatric nutritional risk index (GNRI) and systemic inflammatory response. From 2018 to 2022, 484 uHCC patients treated with LEN (384 males, median age 73).

Bacterial removal using liposomes and an anionic adsorber.

Extracorporeal blood purification techniques using magnetic beads, which physically remove bacteria, fungi, viruses, and cytokines (disease agents) from the blood causing sepsis, have been studied. However, magnetic bead influx, which causes hemolysis and cytotoxicity, is an important issue. This study proposed a novel method for removing Escherichia coli from the blood using liposomes with high biocompatibility.

Impact of the distance of spread through air spaces in non-small cell lung cancer.

Objectives: Spread through air spaces (STAS) is considered a poor prognostic factor in patients with resected non-small lung cell cancer; however, the clinical significance of STAS extent remains unclear. We hypothesized that the further the tumour cells spread from the tumour edge, the worse the prognosis becomes.

Methods: This study retrospectively reviewed the data of 642 patients with completely resected pathological stage I-III non-small lung cell cancer between 2008 and 2018.

Mechanism-Guided Development of Bifunctional Cyclooctenes as Active, Practical, and Light-Gated Bromination Catalysts.

Most molecular catalysts have been developed employing polar functional groups as catalytic sites. However, the use of non-polar functional groups for catalysis has received less attention due to their modest molecular interactions while the bioorthogonal reactivity of non-polar alkenes as substrates is frequently used in click chemistry. In this study, we conducted mechanistic studies on the catalysis of trans-cyclooctene (TCO) derivatives with the strained olefin as the catalytic site using kinetic and computational analyses to aid the design of more active olefin catalysts.

Biologics treatment for eosinophilic chronic rhinosinusitis complicated by bronchial asthma: Narrative review.

There are 4 subtypes of chronic rhinosinusitis (CRS): eosinophilic CRS with nasal polyps (ECRSwNP), ECRS without NPs (ECRSsNP), non-ECRSwNP, and non-ECRSsNP. Most ECRS cases are categorized as ECRSwNP, and the number of patients with ECRSwNP has recently increased. ECRS is associated mainly with helper T-cell type 2 inflammation and eosinophils.

Naloxone selectively inhibits vasoconstriction caused by phenylephrine but not endogenous noradrenaline in the rat mesenteric vasculature.

Although naloxone is an antagonist of the opioid µ receptor, its effect on the peripheral sympathetic nerve function in the blood vessels has not yet been definitively elucidated. Therefore, we examined the effects of naloxone on vasoconstriction of the vascular smooth muscle of rats. Isolated rat mesenteric vascular-intestinal loop preparations were treated with either endogenous or exogenous α adrenoceptor agonists followed by prazosin, a selective antagonist of the α adrenoceptor, or naloxone, and noradrenaline overflow was measured.

Relationship between internal diameter and vasoconstriction in human varicose veins.

Varicose veins are common lower extremity venous disorders characterized by dilated veins and incompetent valves. Although maintaining the required vein wall tone for adaptive responses depends on a proper contractile function of the human saphenous smooth muscle, the contractile properties of varicose veins are mostly unknown. We investigated the relationship between contractile responses and the internal diameter of human saphenous varicose veins.

Effect of 10-minute oropharyngeal exercise on the apnoea-hypopnoea index.

Previously reported oropharyngeal exercises are long and difficult to perform. Therefore, we created a 10-min daily oropharyngeal exercise program and conducted a study to confirm its effectiveness. Twenty-five participants whose apnoea-hypopnoea index (AHI) values were greater than 5 were enrolled.

Efficacy of durvalumab plus tremelimumab treatment for unresectable hepatocellular carcinoma in immunotherapy era clinical practice.

Aim: Since the development of tremelimumab plus durvalumab (Dur/Tre) for unresectable hepatocellular carcinoma (uHCC), it has been used as not only an initial but also later line treatment in clinical practice. This study aimed to elucidate clinical prognostic factors for progression-free survival (PFS) in Dur/Tre treatment cases.

Methods: Enrolled were 183 uHCC patients treated with Dur/Tre from 2023 to May 2024 (median age, 74 years; male patients, 152; Child-Pugh class A:B, 150:33; Barcelona Clinic Liver Cancer stage B:C, 59:124; initial line use, 64).

Complete resection of a recurrent bronchogenic cyst tightly adhered to the left atrium using cardiopulmonary bypass: a case report.

Background: Most surgeons agree that symptomatic mediastinal bronchogenic cysts should be resected, and complete resection is considered mandatory to avoid recurrence. However, a symptomatic mediastinal bronchogenic cyst sometimes adheres to a vital organ, making complete resection hazardous. In such case, surgical resection using cardiopulmonary bypass should be performed to achieve complete resection.

Prognostic Efficacy of the Albumin Grade in Patients with Hepatocellular Carcinoma.

We previously found that "albumin grade", formerly called the "ALBS grade," demonstrated significant capability for prognostic stratification in hepatocellular carcinoma (HCC) patients treated with lenvatinib. The purpose of the present study was to compare the performance of the albumin grade with that of the modified albumin-bilirubin (mALBI) grade in predicting overall survival of HCC patients with different BCLC stages and treatment types. We enrolled 7,645 Japanese patients newly diagnosed with HCC using the Akaike information criteria (AIC), likelihood ratio, and C-index in different Barcelona Clinic Liver Cancer (BCLC) stages and treatments.

Differential Suppressive Effects of Rho Kinase Inhibitor Fasudil on Serotonin- and Noradrenaline-Induced Contractions of Human Internal Thoracic Arteries and Saphenous Veins.

Rho kinase inhibitor fasudil exerts therapeutic effects against vasospasms. In this study, we aimed to compare its suppressive effects on serotonin (5-HT)- and noradrenaline (NAd)-induced contractions of human endothelium-denuded internal thoracic arteries (ITAs) and saphenous veins (SVs). NAd and 5-HT induced concentration-dependent contractions in both ITAs and SVs.

Fully planar solar-pumped fiber laser with 0.1% slope efficiency.

A slope efficiency of 0.1% has been achieved for a fully planar solar-pumped fiber laser (SPFL) with a diameter of 30 cm and an output power of 34 mW. The fiber length is constrained to 400 m, but numerical simulations indicate that the maximum laser output power can be elevated to 113 mW by simply extending the length of the fiber and housing it in the same body.

Lenvatinib versus Sorafenib Second-Line Therapy in Patients with Hepatocellular Carcinoma Progressed to Atezolizumab plus Bevacizumab: A Retrospective Real-World Study.

Introduction: The most frequently used first-line treatment in patients with advanced hepatocellular carcinoma (HCC) is atezolizumab plus bevacizumab. Upon progression after this treatment, the standard of care in many countries is sorafenib, due to the lack of reimbursement for other drugs. Several randomized trials are currently underway to clarify the best second-line therapy in patients with HCC.
