Persistent body-weight change on achalasia and peroral endoscopic myotomy: a multicenter cohort study.

Background: The distribution of body weight in patients with achalasia and after peroral endoscopic myotomy (POEM) has not been investigated. The role of body weight assessment after treatment remains unclear.

Methods: Using the multicenter achalasia cohort, the frequency of underweight (body mass index [BMI] < 18.

Accuracy of cephalometric landmark and cephalometric analysis from lateral facial photograph by using CNN-based algorithm.

Cephalometric analysis is the primary diagnosis method in orthodontics. In our previous study, the algorithm was developed to estimate cephalometric landmarks from lateral facial photographs of patients with normal occlusion. This study evaluates the estimation accuracy by the algorithm trained on a dataset of 2320 patients with added malocclusion patients and the analysis values.

Position statement of the World Endoscopy Organization: Role of endoscopy in screening, diagnosis, and treatment of esophageal superficial squamous neoplasia.

Esophageal squamous cell carcinoma (ESCC) remains a significant global health challenge, being the sixth leading cause of cancer mortality with pronounced geographic variability. The incidence rates range from 125 per 100,000 in northern China to 1-1.5 per 100,000 in the United States, driven by environmental and lifestyle factors such as tobacco and alcohol use, dietary habits, and pollution.
