Rationale:
Coronavirus disease (COVID-19) is a global threat to
health. Its inflammatory characteristics are incompletely understood.
Objectives:
To define the cytokine profile of COVID-19 and to
identify evidence of immunometabolic alterations in those with severe
illness.
Methods:
Levels of IL-1β, IL-6, IL-8, IL-10, and sTNFR1
(soluble tumor necrosis factor receptor 1) were assessed in plasma from healthy
volunteers, hospitalized but stable patients with COVID-19
(COVID
stable
patients), patients with COVID-19 requiring ICU
admission (COVID
ICU
patients), and patients with severe
community-acquired pneumonia requiring ICU support (CAP
ICU
patients).
Immunometabolic markers were measured in circulating neutrophils from patients
with severe COVID-19. The acute phase response of AAT (alpha-1 antitrypsin) to
COVID-19 was also evaluated.
Measurements and Main Results:
IL-1β, IL-6, IL-8, and sTNFR1
were all increased in patients with COVID-19. COVID
ICU
patients could
be clearly differentiated from COVID
stable
patients, and demonstrated
higher levels of IL-1β, IL-6, and sTNFR1 but lower IL-10 than
CAP
ICU
patients. COVID-19 neutrophils displayed altered
immunometabolism, with increased cytosolic PKM2 (pyruvate kinase M2),
phosphorylated PKM2, HIF-1α (hypoxia-inducible factor-1α), and
lactate. The production and sialylation of AAT increased in COVID-19, but this
antiinflammatory response was overwhelmed in severe illness, with the IL-6:AAT
ratio markedly higher in patients requiring ICU admission
(
P
< 0.0001). In critically unwell patients
with COVID-19, increases in IL-6:AAT predicted prolonged ICU stay and mortality,
whereas improvement in IL-6:AAT was associated with clinical resolution
(
P
< 0.0001).
Conclusions:
The COVID-19 cytokinemia is distinct from that of other
types of pneumonia, leading to organ failure and ICU need. Neutrophils undergo
immunometabolic reprogramming in severe COVID-19 illness. Cytokine ratios may
predict outcomes in this population.
Introductory psychology (Intro Psych) is one of the most popular and frequently taught courses on college campuses, yet educators in psychology have limited knowledge about what is covered in classes around the nation or the extent to which class content reflects the current scope of the discipline. There is no explicit model to guide course content selection for the intro course, which poses substantial challenges for instructors. This article proposes a new model for teaching the intro course that integrates (a) scientific foundations, (b) 5 major domains or pillars of knowledge (biological, cognitive, developmental, social and personality, and mental and physical health), and (c) cross-cutting themes relevant to all domains (cultural and social diversity, ethics, variations in human functioning, and applications; American Psychological Association, 2014). We advocate for national assessment of the course, a similar introductory course for majors and nonmajors, the inclusion of experiential or laboratory components, and additional training resources for instructors of the intro course. Given the exponential growth of psychological knowledge and applications during the past decades, we caution against attempting to provide exhaustive coverage of all topic areas of psychology in a one-semester course. We conclude by discussing the challenges that lie ahead for the discipline of psychology as it launches this new model for Intro Psych.
Recent revisions of deterrence theory have highlighted the powerful effects of personal and vicarious punishment avoidance on criminal activity. The present paper reports on an application of Stafford and Warr's [Stafford, M.C., Warr, M., 1993. A reconceptualization of general and specific deterrence. J. Res. Crime Delinq. 30 (2), 123-135] reconceptualisation of deterrence theory to a group of recidivist drink drivers to explain their self-reported offending behaviours. The analysis indicated that punishment avoidance exerted the greatest influence on self-reported offending behaviours, although perceptions of arrest certainty and severity also appear associated with drink driving offences. In contrast, vicarious exposure to others who have been punished or avoided punishment was not associated with further drink driving behaviours. The results suggest that recidivist drink drivers are not heavily influenced by vicarious experiences, and that past behaviour is an efficient predictor of future behaviour. The findings have direct implications for the reconceptualisation and application of deterrence models to elucidate offending behaviours.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
