The efficacy and safety of multi-loop traction device for gastric endoscopic submucosal dissection: a single center prospective pilot study.

Although gastric endoscopic submucosal dissection (ESD) is widely used, the degree of difficulty varies greatly depending on the lesion. Since the multi-loop traction device (MLTD) has been suggested to shorten the procedure time in colorectal ESD, we examined the efficacy and safety of using the MLTD in gastric ESD. Thirty patients with gastric neoplasms were prospectively enrolled from February 2022 to December 2022, and the outcomes of ESD with the MLTD were evaluated.

Optimal medical therapy after percutaneous coronary intervention in very elderly patients with coronary artery disease.

Background: It is still unclear whether optimal medical therapy (OMT) after percutaneous coronary intervention (PCI) has beneficial effects on long-term clinical outcomes in patients aged ≥80 years with coronary artery disease (CAD).

Methods: This study analyzed the time to the first major adverse clinical event including death or nonfatal myocardial infarction (MI), for up to 3 years after PCI using multicenter registry data. Data for 1056 patients aged > 80 years successfully treated with PCI were included in the analysis.

A Stratified Analysis of the Risk Associated With Low Body Mass Index for Patients After Percutaneous Coronary Intervention.

Aims: The relationship between low body mass index (BMI) and prognostic factors for patients with coronary artery disease, commonly observed in elderly individuals in Japan, is important. Few studies have evaluated the prognosis for patients with low BMI after percutaneous coronary intervention (PCI). Using a multivariable-adjusted model and data from a prospective cohort registry, we analyzed the risk associated with low BMI for patients after PCI.

Evaluation of Prognostic Factors for Unresectable or Recurrent Gastric Cancer Treated with Nivolumab.

We therefore focused on the efficacy of statin therapy in extremely elderly patients. This study investigated the efficacy of statins for secondary prevention in patients over 75 years old.

Predictive Significance of Promoter DNA Methylation of in Metachronous Gastric Cancer.

Purpose: Promoter DNA methylation of various genes has been associated with metachronous gastric cancer (MGC). The cancer-specific methylation gene, , has been implicated in the occurrence of residual gastric cancer. We evaluated whether DNA methylation of could be a predictive biomarker of MGC using specimens of MGC developing on scars after endoscopic submucosal dissection (ESD).

Stratification Analysis of Statin Effect on Major Adverse Cardiac Events After Percutaneous Coronary Intervention in Patients on Hemodialysis.

The statin use in patients on hemodialysis remains controversial, and no beneficial effects of statin on the reduction of adverse cardiovascular events have been reported in these patients. This study used stratification analysis to examine the clinical factors in patients on hemodialysis who could benefit from statin for secondary prevention. This prospective multicenter study included 234 consecutive patients on hemodialysis with coronary artery disease who underwent successful reperfusion therapy with percutaneous coronary intervention.

Healing of iatrogenic double-barrel left main coronary artery dissection extending to the left anterior descending artery.

Iatrogenic left main coronary artery (LMCA) dissection is a complication inadvertently caused by the interventional cardiologist and can have significant consequences. A 38-year-old man presented to hospital with non-ST-elevation myocardial infarction. Coronary angiography (CAG) revealed an obstructed proximal left circumflex artery (LCx) that was successfully treated with revascularization using a drug-eluting stent (DES).

Renal Dysfunction as a Predictor of Slow-Flow/No-Reflow Phenomenon and Impaired ST Segment Resolution After Percutaneous Coronary Intervention in ST-Elevation Myocardial Infarction With Initial Thrombolysis in Myocardial Infarction Grade 0.

Background: The slow-flow/no-reflow phenomenon and impaired ST segment resolution (STR) following primary percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI) predict unfavorable prognosis and are characterized by obstruction of the coronary microvascular. Several predictors of slow-flow/no-reflow have been revealed, but few studies have investigated predictors of slow-flow/no-reflow and STR exclusively in acute myocardial infarction patients with initial Thrombolysis in Myocardial Infarction (TIMI) Grade 0.

Methods and results: In all, 279 STEMI patients with initial TIMI Grade 0 were enrolled in the study.

Effects of empagliflozin in different phases of diabetes mellitus-related cardiomyopathy: a prospective observational study.

Background: Diabetes mellitus-related cardiomyopathy (DMCMP), defined as left ventricular (LV) dysfunction caused by hyperglycemia in the absence of coronary artery disease, leads to heart failure (HF). Previous studies have shown that treatment with sodium-glucose co-transporter 2 inhibitor (SGLT2i) reduces the risk of exacerbation of HF. The beneficial effects of SGLT2i on HF depend not only on indirect actions such as osmotic diuresis but also on direct actions on the myocardium, leading to improvements in LV function.

Painful Left Bundle Branch Block Syndrome Complicated by Iron-Overload Cardiomyopathy.

Painful left bundle branch block (LBBB) syndrome is a rare disease that presents as simultaneous chest pain and transient LBBB without myocardial ischemia. We diagnosed a 72-year-old Japanese man with painful LBBB syndrome complicated by iron-overload cardiomyopathy. Phlebotomy was initially performed to improve myocardial iron deposition and conductive disturbance.

Usefulness of endoscopic submucosal dissection for superficial esophageal squamous cell carcinoma in elderly patients: a single-center retrospective cohort study.

Background: The effectiveness of endoscopic treatment for superficial esophageal squamous cell carcinoma in the elderly is unclear.

Methods: We retrospectively studied efficacy and safety of endoscopic submucosal dissection for superficial esophageal squamous cell carcinoma in 358 patients at our hospital from July 2005 to December 2018. Patients were divided into elderly (≥75 years) and young (≤74 years) groups.

Tracheobronchial Obstruction Due to Blood Clots in Acute Pulmonary Embolism with Cardiac Arrest Managed with Extracorporeal Membrane Oxygenation.

A 66-year-old Japanese woman developed pulseless electrical activity following an acute pulmonary embolism and was treated with thrombolytic therapy. She remained hemodynamically unstable and therefore underwent extracorporeal membrane oxygenation (ECMO). While receiving treatment with ECMO, blood clots induced by endobronchial hemorrhage caused tracheobronchial airway obstruction, leading to ventilatory defect.

Rate Versus Rhythm Control in Tachycardia-Induced Cardiomyopathy Patients with Persistent Atrial Flutter.

Tachycardia-induced cardiomyopathy (TIC) is a potentially reversible cardiomyopathy caused by tachyarrhythmia. For atrial flutter (AFL) -induced TIC, a rhythm control strategy, such as catheter ablation, has been recommended. However, the efficacy of rate control has remained unclear due to the difficulty of achieving control using arrhythmic medications.

Barrett's Esophageal Adenocarcinoma Involving a White Globe Appearance within the Long-Segment Barrett's Esophagus.

The diagnosis of Barrett's esophageal adenocarcinoma (BEA) in patients with Barrett's esophagus (BE) using endoscopy can be difficult and there are few specific endoscopic findings for BEA. However, white globe appearance (WGA) has been reported to be a specific endoscopic finding for early gastric cancer. We encountered a 51-year-old male patient with BEA exhibiting WGA.
