Background: Propofol is a key component for the management of sedation and shivering during targeted temperature management (TTM) following cardiac arrest. The cardiac depressant effects of propofol have not been described during TTM and may be especially relevant given the stress to the myocardium following cardiac arrest. The purpose of this study is to describe hemodynamic changes associated with propofol administration during TTM. Methods: This single center, retrospective cohort study evaluated adult patients who received a propofol infusion for at least 30 minutes during TTM. The primary outcome was the change in cardiovascular Sequential Organ Failure Assessment (cvSOFA) score 30 minutes after propofol initiation. Secondary outcomes included change in systolic blood pressure (SBP), mean arterial pressure (MAP), heart rate (HR), and vasopressor requirements (VR) expressed as norepinephrine equivalents at 30, 60, 120, 180, and 240 minutes after propofol initiation. A multivariate regression was performed to assess the influence of propofol and body temperature on MAP, while controlling for vasopressor dose and cardiac arrest hospital prognosis (CAHP) score. Results: The cohort included 40 patients with a median CAHP score of 197. The goal temperature of 33°C was achieved for all patients. The median cvSOFA score was 1 at baseline and 0.5 at 30 minutes, with a non-significant change after propofol initiation ( P = .96). SBP and MAP reductions were the greatest at 60 minutes (17 and 8 mmHg; P

Women continue to remain underrepresented in STEM, and this gender disparity is particularly pronounced in leadership positions. Through in-depth, qualitative interviews of 39 women leaders in STEM, we identify common gender microaggressions they experience, and explore how these microaggressions affect their leadership experience and outcomes in the workplace. Our findings highlight five types of gender microaggressions women most often encounter, and how and when these microaggressions occur. We explore the negative impact that microaggressions can have on women’s work identities and how they can trigger a cycle of rumination and self-doubt that may ultimately result in women choosing to leave STEM. Importantly, we surface the interventional and empowering role that allies play in triggering a redemptive sensemaking process that can support women leaders to build resilience and counter the negative effects of microaggressions.

Background: Asian Canadians and Asian Americans face COVID-19–related discrimination. The objective of this qualitative study was to explore the experiences of Asian health care workers dealing with discrimination, with a focus on racial micro-agressions, in Canada and the United States during the COVID-19 pandemic. Methods: We adopted a qualitative descriptive approach. We used convenience and snowball sampling strategies to recruit participants. We conducted individual, in-depth semistructured interviews with Asian health care workers in Canada and the US via videoconferencing between May and September 2020. Eligible participants had to self-identify as Asian and be currently employed as a health care worker with at least 1 year of full-time employment. We used an inductive thematic approach to analyze the data. Results: Thirty participants were recruited. Fifteen (50%) were Canadians and 15 (50%) were Americans; there were 18 women (60%), 11 men (37%) and 1 nonbinary person. Most of the participants were aged 25–29 years (n = 16, 53%). More than half were nurses (n = 16, 53%); the other participants were attending physicians (n = 5), physiotherapists (n = 3), resident physicians (n = 2), a midwife, a paramedic, a pharmacist and a physician assistant. Two themes emerged from the data: a surge of racial microaggressions related to COVID-19 and a lack of institutional and public acknowledgement. Participants noted that they have experienced an increase in racial microaggressions during the COVID-19 pandemic. They have also experienced threats of violence and actual violence. The largely silent organizational response to the challenges being faced by people of Asian descent and the use of disparaging terms such as “China virus” in the early stages of the pandemic were a substantial source of frustration. Interpretation: Asian health care workers have experienced challenges in dealing with racial microaggressions related to COVID-19 in the US and Canada. More research should be done on the experiences of Asian Americans and Asian Canadians, both during and after the pandemic, and supportive measures should be put in place to protect Asian health care workers.

The study examined how positive attitudes toward Asian Americans impact perceptions of the harmful effects of workplace racial microaggressions enacted against Asian Americans. Positive stereotypes based on the model minority myth portray Asian Americans as hard-working, industrious, and technically competent. Such positive stereotypes can influence individuals' attitudes toward Asian Americans, and as a result, also affect their ability to perceive the harmful effects of subtle types of racial microaggressions, which can be just as harmful, if not more so, than blatant microaggressions. To examine this, we asked participants to read a series of vignettes depicting blatant (microassault) and various types of subtle (microinsult, microinvalidation, and overvalidation) racial microaggressions. As expected, individuals with more positive attitudes toward Asian Americans viewed the blatant microaggressions against Asians as more harmful compared to those who held less positive attitudes. Results also revealed that positive attitudes toward Asian Americans did not influence perceptions of the harmful effects of the subtler microaggressions (overvalidation and microinvalidation). We discuss the implications of these findings.
