Purpose: Current training methods for surgical trainees are inadequate because they are costly, low-fidelity, or have a low skill ceiling. This work aims to expand available virtual reality training options by developing a VR trainer for straight coloanal anastomosis (SCA), one of the Colorectal Objective Structured Assessment of Technical Skills (COSATS) tasks.
Methods: We developed a VR-based SCA simulator to evaluate trainees based on their performance.
Objective: The integration of robotic surgical training in a time-scarce residency program is a challenge for surgical educators. Simulation-based training is a tool that allows residents to acquire the necessary robotic skills without compromising patient safety. This study aimed to assess the learning curve of a robotic inanimate intestinal anastomosis drill.

- The text discusses a parasitic flatworm's life cycle, focusing on the miracidium stage which infects freshwater snails to eventually cause schistosomiasis in humans.
- Researchers created a detailed cellular atlas revealing the 365 cells in the miracidium and identified 19 distinct cell clusters through single-cell RNA sequencing.
- The study found that most of the larva's cells are somatic, with a small percentage being stem cells, and the stem cells display distinct characteristics potentially related to sex.
The current study explored the resistomes and viromes of three Indian ethnic populations: Jaisalmer, Khargone, and Ladakh. These three groups had different dietary habits and antibiotic consumption rates. A resistome analysis indicated that compared to the Jaisalmer (n = 10) group, the burden of antibiotic resistance genes in the gut microbiome was higher in the Khargone (n = 12) and Ladakh (n = 9) groups.

This study aims to determine whether simulation training can predict residents' operative performance, focusing on the gastrojejunal (GJ) anastomosis during robotic pancreatoduodenectomy.
Methods: Twenty-seven general surgery residents completed simulated robotic GJ drills and subsequently performed GJs in the operating room (OR).
