Objective: To explore the pathological features of combined primary hepatic adenosquamous carcinoma (ASC) and hepatocellular carcinoma (HCC).
Methods: The clinicopathological data of one case of cASC-HCC was collected, and the features were analyzed through a literature review.
Results: The male patient was 59 years old and had suffered from inconsistent, upper abdominal pain without any obvious cause for one year. MRI and B-Mode ultrasound images of the upper abdomen showed abnormal signals in the posterior segment of the right lobe of the liver, measuring 12.2 × 7.7 cm. A right hepatectomy was performed. A gross examination revealed an irregular, gray-white infiltrating growing mass, with a partially grayish-yellow area. The histological morphology and immunohistochemical results showed that the tumor was composed of ASC in the gray-white area, accounting for about 80%, and HCC in the grayish yellow area, accounting for about 20%.
Conclusion: cASC-HCC is a rare, malignant tumor with high rates of recurrence and metastasis. It mainly occurs in the right lobe of the liver, especially in older men with a history of hepatitis or intrahepatic cholangiolithiasis. Surgery is the main treatment method.

Background: Patient engagement is a critical but challenging public health priority in behavioral health care. During telehealth sessions, health care providers need to rely predominantly on verbal strategies rather than typical nonverbal cues to effectively engage patients. Hence, the typical patient engagement behaviors are now different, and health care provider training on telehealth patient engagement is unavailable or quite limited.

Bruises can affect the appearance and nutritional value of apples and cause economic losses. Therefore, the accurate detection of bruise levels and bruise time of apples is crucial. In this paper, we proposed a method that combines a self-designed multispectral imaging system with deep learning to accurately detect the level and time of bruising on apples.

Pediatric central nervous system (CNS) tumors represent 20-25% of childhood malignancies, with 35-40 new cases annually in Slovakia. Despite treatment advances, high mortality and poor quality of life in a lot of cases persist. This study assesses the clinical features, treatment modalities, and survival rates of pediatric CNS tumor patients in the single largest center in Slovakia.

Background: The prompt and accurate identification of mild cognitive impairment (MCI) is crucial for preventing its progression into more severe neurodegenerative diseases. However, current diagnostic solutions, such as biomarkers and cognitive screening tests, prove costly, time-consuming, and invasive, hindering patient compliance and the accessibility of these tests. Therefore, exploring a more cost-effective, efficient, and noninvasive method to aid clinicians in detecting MCI is necessary.

Background And Objectives: Guillain-Barré syndrome (GBS), an acute inflammatory disorder of the peripheral nervous system, is characterized by muscle weakness and paralysis. Prompt identification of patients at a high risk of poor outcomes is crucial for timely intervention. In this study, we combined clinical data with nerve conduction study and electromyography data to identify the predictors of GBS outcomes.
