Sex differences in toxicities and survival outcomes among Japanese patients with Stage III colorectal cancer receiving adjuvant fluoropyrimidine monotherapy: A pooled analysis of 4 randomized controlled trials (JCOG2310A).

Background: Fluoropyrimidine remains the key agent of adjuvant chemotherapy for stage III colorectal cancer (CRC). Western studies have shown that female sex is a favorable prognostic factor after surgery, but it is also a risk factor for adverse events (AEs) during adjuvant chemotherapy with fluoropyrimidine. However, little is known about whether sex differences in treatment outcomes exist in this setting in the Asian population.

Clinical outcome and long‑term prognosis after endoscopic submucosal dissection for colorectal tumors in patients aged 75 years or older: a retrospective observational study.

Purpose: To determine the clinical outcomes of endoscopic submucosal dissection (ESD) for colorectal tumors in older patients and predictors of mortality.

Methods: We retrospectively evaluated 207 lesions in 195 consecutive older patients aged ≥ 75 years who underwent ESD for colorectal tumors between January 2007 and December 2018. Outcomes of ESD were evaluated, and the prognosis was assessed in terms of both curability and the patient's baseline physical condition as determined by several indices.

A multicentre prospective registry of one thousand sepsis patients admitted in Indian ICUs: (SEPSIS INDIA) study.

Background: Sepsis is a global health problem with high morbidity and mortality. Low- and middle-income countries have a higher incidence and poorer outcome with sepsis. Large epidemiological studies in sepsis using Sepsis-3 criteria, addressing the process of care and deriving predictors of mortality are scarce in India.

The required experience of open pancreaticoduodenectomy before becoming a specialist in hepatobiliary and pancreatic surgeons: a multicenter, cohort study of 334 open pancreaticoduodenectomies.

Background: Open pancreaticoduodenectomy (OPD) is an essential surgical procedure for expert hepato-biliary-pancreatic (HBP) surgeons. However, there is no standard for how many surgeries must be performed by a surgeon in training before they are considered to have enough experience to ensure surgical safety.

Methods: Cumulative Sum (CUSUM) analysis was performed using the surgical data of OPDs performed during the training period of board-certified expert surgeons of the Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Validation of British Society of Gastroenterology guidelines for acute lower gastrointestinal bleeding from 8,956 cases in Japan.

Background And Aims: We sought to validate the British Society of Gastroenterology (BSG) guidelines for acute lower gastrointestinal bleeding (ALGIB).

Methods: We analyzed 8,956 patients with ALGIB in CODE BLUE-J study and categorized them into four groups based on BSG guidelines. Outcomes included 30-day rebleeding, 30-day mortality, blood transfusion, therapeutic intervention, and severe bleeding.

Out-of-hospital onset versus in-hospital onset for clinical outcomes in spontaneous intramuscular hematoma diagnosed by computed tomography: a retrospective cohort study.

The aging global population and the increasing use of antithrombotic agents have made spontaneous intramuscular hematomas (SIH) a growing concern. The association between the settings of SIH onset and clinical outcomes remains unclear. The aim of this study was to determine these associations.

Pathophysiological Mechanisms of the Onset, Development, and Disappearance Phases of Skin Eruptions in Chronic Spontaneous Urticaria.

Chronic spontaneous urticaria (CSU) is a typical example of an intractable skin disease with no clear cause and significantly affects daily life of patients. Because CSU is a human-specific disease and lacks proper animal model, there are many questions regarding its pathophysiological dynamics. On the other hand, most clinical symptoms of urticaria are notable as dynamic appearance of skin eruptions called wheals.

A Case of Anti-OJ Antibody-positive Antisynthetase Myopathy Diagnosed after Pulmonary Embolization.

Idiopathic inflammatory myopathies, such as dermatomyositis, are implicated as possible risk factors for venous thromboembolism. We herein report the first known case of a 50-year-old woman who presented to our hospital with a fever, chest pain, and elevated creatine kinase levels and was ultimately diagnosed with pulmonary embolism and anti-OJ antibody-positive antisynthetase myopathy. Dermatomyositis may increase the risk of venous thromboembolism, including pulmonary embolism.

Predictors of tolerability for postoperative adjuvant S1 plus docetaxel chemotherapy for gastric cancer: a multicenter retrospective study.

Background: Adjuvant docetaxel plus S1 (DS) chemotherapy after gastrectomy with D2 lymph node dissection is the standard treatment for stage III gastric cancer in Japan; however, some patients are unable to receive adequate drug administration because of the deterioration of their conditions. This study aimed to investigate the correlation between tolerability for postoperative adjuvant DS chemotherapy and prognosis, and the factors affecting tolerability.

Methods: This retrospective study involved patients with stage III gastric cancer who underwent curative resection between 2018 and 2021 from a multicenter database.

Lymphadenectomy and chemotherapy are effective treatments for patients with 2023 international federation of gynecology and obstetrics stage IIC-high risk endometrial cancer in Japan.

Background: In early-stage endometrial cancer (EC), the treatment of aggressive histological subtypes (endometrioid carcinoma grade 3, serous carcinoma, clear-cell carcinoma, undifferentiated carcinoma, mixed carcinoma, and carcinosarcoma) is controversial. We aimed to investigate the treatment of patients with International Federation of Gynecology and Obstetrics (FIGO) stage IC and stage IIC EC according to the 2023 classification.

Methods: We retrospectively identified patients with FIGO 2023 stage IC, IIC-intermediate risk (IIC-I), and IIC-high risk (IIC-H) EC who underwent adjuvant therapy or observation after surgery at eight medical institutions from 2004 to 2023.

Efficacy and safety of the contralateral approach to vascular lesions in the vertebral artery: patient series.

Background: Endovascular treatment is preferred over microsurgical clipping for intracranial aneurysms in the posterior circulation. However, access to lesions, particularly those in the regions of the vertebral artery (VA) and the posterior inferior cerebellar artery (PICA), is technically challenging in terms of the vessel diameter of the ipsilateral VA or the branching angle of the PICA.

Observations: Nine cases of intracranial aneurysms in the region of the PICA, which were endovascularly treated with an approach beyond the vertebrobasilar junction (VBJ) from the contralateral VA in the last 4 years, are described herein.

Early diagnosis of nonconvulsive status epilepticus due to lithium intoxication using 6-channel electroencephalography.

Introduction: Nonconvulsive status epilepticus is a severe complication of lithium intoxication that requires prompt diagnosis and treatment. While conventional electroencephalography (EEG) remains the gold standard for diagnosis for nonconvulsive status epilepticus, its implementation in emergency settings can be challenging and time-consuming. We present a case in which simplified EEG with six electrodes enabled rapid detection and monitoring of nonconvulsive status epilepticus in lithium intoxication in the emergency setting.

Gastro-tracheal fistula following esophageal cancer surgery through the retrosternal route: a case report.

Background: Gastro-tracheal fistula is a rare but serious complication after esophageal surgery, often requiring long-term treatment and invasive procedures. Gastro-tracheal fistula usually occurs through the posterior mediastinal route and rarely through the retrosternal route. No previous reports have described gastro-tracheal fistula after retrosternal route reconstruction was cured by conservative treatment.

Randomized Phase II Trial of Amrubicin Plus Irinotecan Versus Cisplatin Plus Irinotecan in Chemo-naïve Patients With Extensive-Disease Small-Cell Lung Cancer: Results of the Japan Multinational Trial Organization (JMTO) LC 08-01.

Background: We conducted a randomize phase II study to evaluate the efficacy and safety of topoisomerase II inhibitor amrubicin plus topoisomerase I inhibitor irinotecan (AI) compared with cisplatin plus irinotecan (PI) as first-line therapy in patients with extensive-disease (ED) small-cell lung cancer (SCLC).

Patients And Methods: Chemo-naïve patients with pathologically proven ED-SCLC (including limited disease (LD) SCLC with malignant effusion) were enrolled. Patients were randomized 1:1 to receive either AI (amrubicin 90mg/m on day 1 and irinotecan 50mg/m on days 1 and 8 of a 21-day cycle) or PI (cisplatin 60mg/m on day 1 and irinotecan 60mg/m on days 1, 8 and 15 of a 28-day cycle).

Initial Findings Concerning the Latest Self-Expandable Evolut FX Valve: A Report Using OCEAN-TAVI Registry Data.

Data concerning the clinical effect of the latest-generation self-expandable transcatheter heart valve (Evolut FX) remain limited. We aimed to assess the in-hospital outcomes of 3 bioprosthetic valves (Evolut EPO, PRO+, and FX). We analyzed data from a Japanese multicenter registry involving 634 consecutive patients who underwent transcatheter aortic valve replacement with Evolut FX up until October 2023.
