ABSTRACT

Due to immunosuppressive therapy, transplant patients are more susceptible to viral and bacterial infections. A potentially deadly new virus haunted us in 2020: SARS-CoV­2, causing coronavirus disease 19 (COVID-19). We analyzed the consequences of this previously unknown risk for our living-donor transplant program in the first year of the pandemic. After the complete lockdown in spring 2020, our transplant center in Linz resumed the living-donor kidney transplantation program from June to September 2020, between the first and second waves of COVID-19 in Austria. We compared the outcomes of these living-donor kidney transplantations with the transplant outcomes of the corresponding periods of the three previous years. From June 4 to September 9, 2020, five living-donor kidney transplantations were performed. All donors and recipients were screened for COVID 19 infection by PCR testing the day before surgery. Kidney transplant recipients remained isolated in single rooms until discharge from hospital. All recipients and donors remained SARS-CoV­2 negative during the follow-up of 10 months and have been fully vaccinated to date. The number of living transplants in the studied period of 2020 was constant compared to the same months of 2017, 2018, and 2019. Living-donor kidney transplantation can be continued using testing for SARS-CoV­2 and meticulous hygienic precautions in epidemiologically favorable phases of the SARS-CoV­2 pandemic. Donors and recipients should be carefully selected and informed about risks and benefits.

ABSTRACT

BACKGROUND: Postoperative pain influences rehabilitation, postoperative complications and quality of life. Despite its impact, there are no uniform treatment guidelines. Different centers seem to use various strategies. This study aims to analyze pain management regimens used after anatomic VATS resections in Austrian thoracic surgery units, with a special interest in opioid usage and strategies to avoid opioids. METHODS: A questionnaire was designed to assess the use of regional anesthesia, postoperative pain medication and characteristics of individual pain management regimens. The questionnaire was sent to all thoracic surgery units in Austria, with nine out of twelve departments returning them. RESULTS: All departments use regional anesthesia during the procedure. Four out of nine centers use epidural analgesia or an intercostal catheter for postoperative regional anesthesia in at least 50% of patients. Two departments follow an opioid restrictive regimen, five depend on the visual analogue scale (VAS) and two administer opioids on a fixed schedule. Three out of nine departments use NSAIDs on a fixed schedule. The most used medication is metamizole (eight out of nine centers; six on a fixed schedule, two depending on VAS) followed by piritramide (six out of nine centers; none as a fixed prescription). CONCLUSIONS: This study reflects the heterogeneity in postoperative pain treatment after VATS anatomic lung resections. All departments use some form of regional anesthesia in the perioperative period; prolonged regional anesthesia is not utilized uniformly to reduce opioid consumption, as suggested in enhanced recovery after surgery programs. More evidence is needed to optimize and standardize postoperative pain treatment.

ABSTRACT

Our area of interest is robotic-based rehabilitation after stroke, and our goal is to help patients achieve optimal motor learning during high-intensity repetitive movement training through the assistance of robots. It is important, that the robotic assistance is adapted to the patients' abilities, thereby ensuring that the device is only supporting the patient as necessary ("assist-as-needed"). We hypothesize that natural and learning-effective human-machine interaction can be achieved by programming the robot's control, so that it emulates how a physiotherapist adaptively supports the patients' limb movement during stroke rehabilitation. This paper introduces the design of a novel interactive device Bi-Manu-Interact. This device is suited to be used as an experimental setup for the investigation of haptic human-human interaction and for collecting data to model therapists' haptic behavior. In this paper, we present mechanical and sensory specifications as well as tasks visualizations for future investigations. Results of a pilot clinical evaluation of the Bi-Manu-Interact with nine stroke patients are also presented in this work.

ABSTRACT

An attractive mechanism to break supersymmetry in vacua with zero vacuum energy arose in E(8) x E(8) heterotic models with hidden sector gaugino condensate. An H flux balances the exponentially small condensate on shell and fixes the complex structure moduli. At quantum level this balancing is, however, obstructed by the quantization of the H flux. We show that the warped flux compactification background in heterotic M theory can solve this problem through a warp-factor suppression of the integer flux relative to the condensate. We discuss the suppression mechanism both in the M theory and the four-dimensional effective theory and provide a derivation of the condensate's superpotential which is free of delta-function squared ambiguities.
