Background: Although the mental health burden in healthcare workers caused by COVID-19 has gained increasing attention both within the profession and through public opinion, there has been a lack of data describing their experience; specifically, the mental wellbeing of healthcare workers in the intensive care unit (ICU), including those redeployed. Aims: The authors aimed to compare the mental health status of ICU healthcare workers (physicians, nurses and allied health professionals) affected by various factors during the COVID-19 pandemic; and highlight to policymakers areas of staff vulnerabilities in order to improve wellbeing strategies within healthcare systems. Methods: An online survey using three validated scales was conducted in France, the UK, Italy, Mainland China, Taiwan, Egypt and Belgium. Findings: The proportion of respondents who screened positive on the three scales across the countries was 16–49% for depression, 60–86% for insomnia and 17–35% for post-traumatic stress disorder. The authors also identified an increase in the scores with longer time spent in personal protective equipment, female gender, advancing age and redeployed status. Conclusion: The high prevalence of mental disorders among ICU staff during the COVID-19 crisis should inform local and national wellbeing policies.

Background Within surgery, assistive robotic devices (ARD) have reported improved patient outcomes. ARD can offer the surgical team a “third hand” to perform wider tasks and more degrees of motion in comparison with conventional laparoscopy. We test an eye-tracking based robotic scrub nurse (RSN) in a simulated operating room based on a novel real-time framework for theatre-wide 3D gaze localization in a mobile fashion. Methods Surgeons performed segmental resection of pig colon and handsewn end-to-end anastomosis while wearing eye-tracking glasses (ETG) assisted by distributed RGB-D motion sensors. To select instruments, surgeons (ST) fixed their gaze on a screen, initiating the RSN to pick up and transfer the item. Comparison was made between the task with the assistance of a human scrub nurse (HSNt) versus the task with the assistance of robotic and human scrub nurse (R&HSNt). Task load (NASA-TLX), technology acceptance (Van der Laan’s), metric data on performance and team communication were measured. Results Overall, 10 ST participated. NASA-TLX feedback for ST on HSNt vs R&HSNt usage revealed no significant difference in mental, physical or temporal demands and no change in task performance. ST reported significantly higher frustration score with R&HSNt. Van der Laan’s scores showed positive usefulness and satisfaction scores in using the RSN. No significant difference in operating time was observed. Conclusions We report initial findings of our eye-tracking based RSN. This enables mobile, unrestricted hands-free human–robot interaction intra-operatively. Importantly, this platform is deemed non-inferior to HSNt and accepted by ST and HSN test users.

Nipple aspirate fluid is the physiological biofluid lining ductal epithelial cells. Historically, cytology of nipple fluid has been the gold standard diagnostic method for assessment of ductal fluid in patients with symptomatic nipple discharge. The role of biomarker discovery in nipple aspirate fluid for assessment of asymptomatic and high-risk patients is highly attractive but evaluation to date is limited by poor diagnostic accuracy. However, the emergence of new technologies capable of identifying metabolites that have been previously thought unidentifiable within such small volumes of fluid, has enabled testing of nipple biofluid to be re-examined. This review evaluates the use of new technologies to evaluate the components of nipple fluid and their potential to serve as biomarkers in screening.

Aim To determine the effect of CPR delivery surface (e.g. firm mattress, floor, backboard) on patient outcomes and CPR delivery. Methods We searched Medline, Cochrane Library and Web of Science for studies published since 2009 that evaluated the effect of CPR delivery surface in adults and children on patient outcomes and quality of CPR. We included randomised controlled trials only. We identified pre-2010 studies from the 2010 ILCOR evaluation of this topic. Two reviewers independently screened titles/ abstracts and full-text papers, extracted data and assessed risk of bias. Evidence certainty for each outcome was evaluated using GRADE methodology. Where appropriate, we pooled data in a meta-analysis, using a random-effects model. Results Database searches identified 2701 citations. We included seven studies published since 2009. We analysed these studies together with the four studies included in the previous ILCOR review. All included studies were randomised controlled trials in manikins. Certainty of evidence was very low. Increasing mattress stiffness or moving the manikin from the bed to the floor did not improve compression depth. Use of a backboard marginally improved compression depth (mean difference 3 mm (95% CI 1–4). Conclusion The use of a backboard led to a small increase in chest compression depth in manikin trials. Different mattress types or delivery of CPR on the floor did not affect chest compression depth. PROSPERO CRD42019154791.
