Upper gastrointestinal stenosis, which can be congenital or acquired, can lead to dysphagia. The association between trisomy 17p syndrome, a rare chromosomal abnormality, and upper gastrointestinal stenosis is unclear. A 20-year-old man diagnosed with trisomy 17p syndrome was referred to our department due to recurrent vomiting.

Background: Although they are fast-growing populations in the United States, little is known about survival outcomes of Hispanic and Asian patients after in-hospital cardiac arrest.

Methods And Results: In Get With The Guidelines-Resuscitation, we identified Asian, Hispanic, and White adults with in-hospital cardiac arrest during 2005 to 2023. Using multivariable models, we compared rates of survival to discharge separately for Asian and Hispanic patients versus White patients, as well as rates of sustained return of spontaneous circulation for ≥20 minutes and favorable neurologic survival as secondary outcomes.

Background: A wearable cardioverter defibrillator (WCD) is indicated for a limited period in patients at high risk of sudden cardiac death (SCD). Nonischemic heart failure (HF) is common among Japanese patients with HF. The aim of this study was to evaluate the incidence of fatal arrhythmias during WCD use and the clinical outcomes after WCD withdrawal in Japanese patients with HF.

Background: Zero-fluoroscopic pulsed field ablation (PFA) is the next step in advancing pulmonary vein isolation (PVI) for atrial fibrillation (AF).

Methods: A workflow incorporating a variable-loop circular PFA catheter, intracardiac echocardiography (ICE), and a visualized sheath was applied to 15 paroxysmal AF patients.

Results: It consisted of three steps: (1) positioning a non-magnetic mapping catheter in the coronary sinus after creating a right atrial matrix, (2) transseptal puncture with the sheath advancement to the left atrium under ICE guidance, and (3) PFA confirming catheter-tissue contact with tissue proximity indication.

Background: Significant gap remains in the implementation of guideline-directed medical therapy (GDMT) in patients with heart failure after a hospitalization. We aimed to evaluate the use and titration of GDMT at discharge and over a 12-month period after hospital discharge and to identify factors associated with GDMT use and titration.

Methods And Results: The CONNECT-HF (Care Optimization Through Patient and Hospital Engagement Clinical Trial for Heart Failure) trial evaluated the effect of a hospital and postdischarge quality improvement intervention in participants with heart failure with reduced ejection fraction.

Background: We investigate the feasibility of using artificial intelligence (AI) to identify the recurrent laryngeal nerve (RLN) during endoscopic thyroid surgery and evaluated its accuracy.

Methods: In this retrospective study, we develop an AI model using a dataset of endoscopic thyroid surgery videos, including hemithyroidectomy procedures performed between April 2019 and September 2023 at the National Cancer Center Hospital East, Chiba, Japan. Semantic segmentation deep learning methods were applied to analyze the endoscopic thyroid surgery videos.

Background: The cause of chronic thromboembolic pulmonary hypertension (CTEPH) remains largely unknown. Recently, clonal hematopoiesis (CH) has been reported to be associated with cardiovascular and thromboembolic diseases. Here, we investigated the prevalence and clinical impact of CH in patients with CTEPH.

Background: Pyloric gland adenoma (PGA) is a distinct subtype of duodenal adenoma. PGA has been increasingly recognized as a histologically and molecularly distinct entity; however, its endoscopic features have not been precisely described. This study aims to investigate the endoscopic characteristics of duodenal PGA, including the association of their putative precursors, Brunner's gland hyperplasia (BGH), and gastric epithelial heterotopia/metaplasia (GEM/H).

Background: Older patients with multimorbidity often seek care from multiple health care providers and visit several medical institutions. Having a primary care provider who takes overall responsibility for their care may be beneficial. We conducted a survey to identify the characteristics of general practitioners and geriatricians who frequently assume such responsibility for older patients with multimorbidity.

Background: Since it is difficult for expert endoscopists to diagnose early gastric cancer in post-eradication status, it may be critical to evaluate the stratification of high-risk groups using the advance of gastric atrophy or intestinal metaplasia. We tried to determine whether the combination of endoscopic artificial intelligence (AI) diagnosis for the evaluation of gastric atrophy could be a useful tool in both pre- and post-eradication status.

Methods: 270 -positive outpatients (Study I) were enrolled and Study II was planned to compare patients ( = 72) with pre-eradication therapy with post-eradication therapy.

Article Synopsis
  • Evolocumab, a monoclonal antibody approved for treating familial hypercholesterolemia (FH) and hypercholesterolemia, was evaluated in a real-world study in Japan, as data on its effectiveness and safety were previously limited.
  • The study involved 3724 patients with various forms of FH and hypercholesterolemia over 104 weeks, measuring both safety (incidences of adverse reactions) and effectiveness (changes in LDL cholesterol levels).
  • Results indicated that Evolocumab was well tolerated, showing significant reductions in LDL cholesterol levels, with low rates of serious adverse events, suggesting it is a viable treatment option for high-risk patients in Japan.
