Pancreatic cancer is difficult to diagnose early since tumor markers have low sensitivity and specificity. We simultaneously measured serum carbohydrate antigen (CA) 19-9, pancreatic elastase-1, lipase, and amylase, and evaluated the accuracy of a single marker or a combination of two, three, or four markers in the diagnosis of pancreatic ductal adenocarcinoma (PDAC). ⋯ CA19-9 as a single marker is the most accurate in the clinical diagnosis of PDAC. Combination of lipase, amylase, or pancreatic elastase-1 results does not significantly increase the accuracy of PDAC diagnosis.

Locally advanced tongue or tongue base cancer is recommended to be treated by radical resection that is usually detrimental to physiological functions. This study reports the efficacy and treatment outcome of the patients who had received total glossectomy and laryngeal suspension without lip-split mandibulotomy and free flap reconstruction to preserve laryngopharyngeal function. ⋯ Total glossectomy with laryngeal suspension can be successfully applied to locally advanced tongue or tongue base cancer, and benefits the patients with improved survival and preserved physiological function. Especially surgeons for free flap reconstruction are understaffed at some regional or district hospitals.

The accuracy of histopathology diagnosis largely depends on the pathologist's experience. It usually takes over 10 years to cultivate a senior pathologist, and small numbers of them lead to a high workload for those available. Meanwhile, inconsistent diagnostic results may arise among different pathologists, especially in complex cases, because diagnosis based on morphology is subjective. Computerized analysis based on deep learning has shown potential benefits as a diagnostic strategy. ⋯ For AI to assist pathologists in daily practice, to help a pathologist making a definite diagnosis is not the prime purpose at present time. The benefits could come from cancer screening and double-check quality control in a heavy workload which could distract the attention of pathologist during the time constraint examination process. We propose a two-steps method to identify cancerous areas in endoscopic gastric biopsy slices via deep learning. Then a 3D model is used to further mark all the positions of GC in the picture, and the model overcomes the problem that deep learning can't catch all GC.

New psychoactive substances (NPS) have increasingly been illegally synthesized and used around the world in recent years. Due to the large volume and the variety of NPS, most do not have sufficient information about their addictive potential and harmful effects to human subjects. This makes it difficult to evaluate these potential substances of abuse. ⋯ Taiwan Controlled Substances Database (TCSD) includes the collection of controlled substances, relevant experimental and structural information, as well as computational features such as molecular fingerprints and descriptors. Two types of structural search were added: substructure search and topological fingerprint similarity search. A web framework was used to enhance accessibility and usability (https://cs2search.cmdm.tw).

The current study aimed to assess the prevalence of bullying victimization (BV) and its association with psychopathology and suicidality in a nationwide general population. ⋯ Bullying exposure is associated with recent psychopathology and lifetime suicidality. Multifactorial interactive processes contribute to long-term harmful health implications in adulthood. Nevertheless, further research on the relevant mechanisms associated with bullying and potential interventions that can decrease morbidity must be conducted.
