Aim: Malnutrition is associated with poor outcomes in cerebral infarction patients, with research indicating that early nutritional initiation may improve the short-term prognosis of patients. However, evidence supported by big data is lacking. Here, to determine the effect of nutritional initiation during the first 3 days after hospital admission on home discharge rates, propensity score matching was conducted in patients with acute cerebral infarction.

- Automatic surgical workflow recognition is essential for improving context-aware computer-assisted surgery systems, particularly in laparoscopic sigmoidectomy (Lap-S), but previous studies on automatic phase recognition in this area were lacking.
- Researchers developed a deep learning model that analyzes Lap-S video data divided into frame units to recognize 11 surgical phases and actions, achieving an impressive automatic surgical phase recognition accuracy of 91.9%.
- The system demonstrated the ability to perform real-time recognition at 32 frames per second, showcasing its potential for enhancing surgical support technology with high accuracy in detecting both surgical phases and actions.
Objectives: To evaluate the diagnostic performance of deep learning with the convolutional neural networks (CNN) to distinguish each representative parkinsonian disorder using MRI.
Methods: This clinical retrospective study was approved by the institutional review board, and the requirement for written informed consent was waived. Midsagittal T1-weighted MRI of a total of 419 subjects (125 Parkinson's disease (PD), 98 progressive supranuclear palsy (PSP), and 54 multiple system atrophy with predominant parkinsonian features (MSA-P) patients, and 142 normal subjects) between January 2012 and April 2016 was retrospectively assessed.
Objective: The aim of this study was to investigate the additive effect of the active form of vitamin D3 on the gain in back extensor strength through a back extensor exercise.
Design: A total of 107 postmenopausal women with osteoporosis were randomly divided into two groups: the D3 group and the control group. Both groups were treated with calcium and alendronate and undertook the back extensor exercise.
Synovial sarcoma with extensive osteoid production is rare. We report a case of synovial sarcoma of monophasic type with massive ossification. The diagnosis was confirmed by reverse-transcripitase polymerase chain reaction (RT-PCR).
