An "esophageal rosette" sign is useful for predicting favorable outcomes in peroral endoscopic myotomy for esophageal achalasia.

Background: An "esophageal rosette" (ER) sign is one of the endoscopic findings in primary esophageal achalasia. We investigated whether ER was associated with the therapeutic efficacy of peroral endoscopic myotomy (POEM).

Methods: The clinical characteristics and short-term outcomes of POEM were retrospectively evaluated in 69 patients who underwent the procedure for esophageal achalasia.

Direct Catalytic Asymmetric Conjugate Addition of Benzofuran-3(2H)-Ones to α,β-Unsaturated Thioamides: Stereodivergent Synthesis of Rocaglaol.

Rocaglaol, a representative flavagline, has attracted significant attention because of its unique chemical structure and biological activities. This paper reports a mild and scalable copper-catalyzed enantioselective conjugate addition of benzofuran-3(2H)-ones to α,β-unsaturated thioamides. This method allows for the concise synthesis of all possible stereoisomers of a key intermediate of rocaglaol and its derivatives in a highly diastereo- and enantioselective manner using different chiral phosphine ligands.

Giant-cell arteritis on photon-counting detector CT: A case report.

A 77-year-old woman presented to our hospital with a 2-week history of fever, headache, and induration along the bilateral superficial temporal arteries (STAs). The color Doppler ultrasonography of the STA showed a hypoechoic mural thickening surrounding a residual color flow. A contrast-enhanced photon-counting detector (PCD) CT demonstrated mural thickening and stenosis of the bilateral STAs.

Impact of the Coexisting Coronary Artery Disease on Five-Year Outcomes in Lower Extremity Artery Disease Patients Without Chronic Limb-Threatening Ischemia.

Coronary artery disease (CAD) is often noted in patients with lower-extremity artery disease (LEAD). However, the effects of CAD on patients with LEAD have not been clearly investigated. In this study, to investigate the effect of CAD on patients with LEAD without chronic limb-threatening ischemia (CLTI), we compared the five-year clinical outcomes of patients with and without CAD.
