Summary: The goal of this study was to quantify and compare the workload and teamwork during robot-assisted prostatectomy using multi-port da Vinci Xi (MP) and single-port da Vinci SP (SP) robots. The results showed that the workload was lower and the teamwork was better in the MP group compared to the SP group. The significant differences between the two surgical procedures may be due to factors other than the experience of the surgeon and surgical team, such as robot design. The study also suggested that more procedures may be needed to achieve proficiency with the SP system.

Summary: This study evaluated the safety and feasibility of the Da Vinci SP robot system for rectal cancer surgery and found that it had shorter operation time compared with the currently used robot system, but similar outcomes in other measures. These results indicate that the SP robotic system is safe and technically feasible in the short-term.

Summary: This study employs machine learning to predict postoperative pulmonary complications (PPCs) and identify important features of the prediction models. The dataset collected from two hospitals includes perioperative variables. Various algorithms were used for model development and evaluation. The study enrolled 111,212 adult patients, with an overall incidence rate of 8.6% for developing PPCs. The models achieved AUROC of 0.699-0.767 and f1 score of 0.446-0.526. Ten important features were obtained in the prediction models, except for multilayer perceptron. In feature-reduced models with 10 important features, the AUROC was 0.627-0.749 and the f1 score was 0.365-0.485. The number of packed red cells, urine, and rocuronium doses were similar in the three models.

Summary: Bronchodilator therapy during the perioperative period was effective in preserving lung function in COPD patients undergoing surgery for non-small cell lung cancer, with no significant difference in postoperative complications between patients treated with and without bronchodilators.

Summary: The review focuses on Leonardo da Vinci's work and thought related to fluid mechanics, highlighting his use of experimentation as an important mechanism for natural fluid flows. However, it points out that his conclusions did not always align with modern fluid mechanics. Leonardo's works depict multiple and ambiguous meanings of turbulence, while also exploring concepts similar to modern ideas.

Summary: The new SP robot minimizes the number of incisions needed by incorporating a single trocar with a flexible camera and three bi-articulated arms, resulting in a less invasive procedure. A comparison study between patients undergoing robotic-assisted radical prostatectomy (RARP) with the SP robot and the Xi robot showed that the SP group had less blood loss and longer operative time. However, there were no significant differences in postoperative pain scores between the two groups at 6, 12, and 18 hours after surgery.

Summary: A nomogram model was developed to predict postoperative pulmonary complications (PPCs) in thoracoscopic surgery, using data from 905 patients. The model incorporated seven key variables related to PPCs and showed good predictive performance in distinguishing the risk of PPCs, aiding in making reasonable treatment choices. With high C-indices and well-fitted calibration curves, the nomogram offers a reliable tool for assessing and managing PPCs in thoracoscopic surgery.

Summary: Leonardo Da Vinci left many clues, rules and knowledge about the consequences of friction and methods to reduce it in his manuscripts. The Italian polymath studied aspects related to wear, lubrication, and contact mechanics, which form the basis of modern tribology. His knowledge, obtained through intuitive means, led to solutions and concepts without complex processes of reasoning. Through sketches and reflections, Da Vinci enhanced his understanding of the origin and consequences of relative movement between bodies, showing the importance in present-day tribology.

Summary: This study evaluated the feasibility and safety of single-port robotic pancreatic surgery (SPRPS) using the da Vinci SP system. The results showed that SPRPS was safe and feasible in selected patients, with fewer postoperative complications and good recovery. However, further research and surgical experience are needed to determine the indications for SPRPS.

Summary: This study examined the incidence of postoperative pulmonary complications (PPCs) and their associated risk factors among general surgery patients in a public hospital in South Africa. The results showed that PPCs are common in low- and middle-income countries and these complications worsen patient outcomes and increase mortality.

Summary: This study evaluated the safety and feasibility of robotic single-port transabdominal preperitoneal inguinal hernia repair (SP-TAPP) and compared it to the robotic multiport technique (MP-TAPP). The results showed that SP-TAPP is safe and feasible, with similar postoperative morbidity, higher same-day discharge rates, and quicker postoperative recovery compared to MP-TAPP.
