Objective: Very few studies have focused on the experience of the patient-side assistant in robotic cardiac surgery. We investigated whether the retirement of a highly experienced robotic patient-side assistant and replacement with a new assistant had an effect on surgical outcomes.
Methods: In 4/2016, the established patient-side assistant retired after spending 8 months training a new patient-side assistant. A retrospective analysis of 216 patients was performed; 108 patients over a 9 month period just prior to arrival of the new patient-side assistant (Group 1), and 108 patients over 8 months just subsequent to departure of the established assistant (Group 2). Case distribution, pre-operative characteristics, and surgical outcomes were collected and compared.
Results: Case volume increased in Group 2 with the new assistant. The mean age and rate of pre-op CVA for Group 1 was lower, but, otherwise, patient demographics were not significantly different. Group 1 had more intracardiac cases and group 2 had more triple-vessel TECABs. Overall operative time was not different between the two groups. Perioperative outcomes including hospital length of stay major adverse cardiovascular events and mortality were similar between the two groups.
Conclusions: We conclude that the transition to a new robotic cardiac surgical patient-side assistant does not have to affect the progress of a busy robotic program. If adequate time for training and gradual assumption of responsibility is ensured, it is feasible to make this transition without loss of volume or compromise in patient outcomes.

We introduce a novel approach for reduced-port robotic-assisted thoracoscopic surgery for thoracic neoplasms. Surgery is performed via single- or two-incision. Main incision( 4 cm) is placed on 8th intercostal space on mid-axillary line and second incision, if needed, is placed on 5th intercostal space on anterior axillary line.

Objective: Minimally invasive stabilization of non- and minimally displaced acetabular fractures using intraoperative, robot-assisted three-dimensional (3D) imaging and a navigation system.
Indications: Nondisplaced or only minimally displaced fractures of the acetabulum.
Contraindications: Comminuted and highly displaced fractures of the acetabulum, protrusion of the femoral head into the pelvis with the need for open reduction, lack of possibility of intraoperative navigation.

Article Synopsis
- Robotic pancreaticoduodenectomy (R-PD) is gaining attention for treating periampullary tumors, and this study focuses on optimizing the multiple scope transition (MST) method to improve surgical efficiency and safety.
- An analysis of 61 R-PD surgeries showed median operation durations and varying scope transition times, which improved as surgical experience increased, with no intraoperative complications reported.
- The study concludes that the MST method enhances the surgical field, making R-PD safer and more effective for broader application.
Designing the User Interface of a Nitroglycerin Dose Titration Decision Support System: User-Centered Design Study.
Appl Clin Inform

School of Nursing, Queensland University of Technology (QUT), Brisbane, Australia.
Background: Nurses adjust intravenous nitroglycerin infusions to provide acute relief for angina by manually increasing or decreasing the dosage. However, titration can pose challenges, as excessively high doses can lead to hypotension, and low doses may result in inadequate pain relief. Clinical decision support systems (CDSSs) that predict changes in blood pressure for nitroglycerin dose adjustments may assist nurses with titration.

Background: Since the amendments to the Baden-Württemberg Psychiatric Assistance Act, psychiatric patients who are treated involuntarily can be admitted to open wards. As a result, a comprehensive research project was carried out to implement an open-door policy. This work evaluates the attitudes of patients and therapeutic teams.
