TL;DR: It is demonstrated that it is possible and instructive to define professionalism in terms of tangible behaviors, and focusing on behaviors rather than attributes may facilitate discussion, assessment, and modeling of professionalism in both medical education and clinical care.
Abstract: PurposeAlthough professionalism has always been a core value in medicine, it has received increasingly explicit attention over the past several years Unfortunately, the terms used to explain this competency have been rather abstract This study was designed to identify and prioritize behavi

TL;DR: This paper reflects on global health partnerships by revisiting the origins of global health and deconstructing the notion of partnership, mainly through being explicit about past and present inequalities between Northern and Southern universities that this discipline has thus far eluded.
Abstract: Global health conceives the notion of partnership between North and South as central to the foundations of this academic field. Indeed, global health aspires to an equal positioning of Northern and Southern actors. While the notion of partnership may be used to position the field of global health morally, this politicization may mask persisting inequalities in global health. In this paper, we reflect on global health partnerships by revisiting the origins of global health and deconstructing the notion of partnership. We also review promising initiatives that may help to rebalance the relationship. Historical accounts are helpful in unpacking the genesis of collaborative research between Northerners and Southerners – particularly those coming from the African continent. In the 1980s, the creation of a scientific hub of working relationships based on material differences created a context that was bound to create tensions between the alleged “partners”. Today, partnerships provide assistance to underfunded African research institutions, but this assistance is often tied with hypotheses about program priorities that Northern funders require from their Southern collaborators. African researchers are often unable to lead or contribute substantially to publications for lack of scientific writing skills, for instance. Conversely, academics from African countries report frustrations at not being consulted when the main conceptual issues of a research project are discussed. However, in the name of political correctness, these frustrations are not spoken aloud. Fortunately, initiatives that shift paternalistic programs to formally incorporate a mutually beneficial design at their inception with equal input from all stakeholders are becoming increasingly prominent, especially initiatives involving young researchers. Several concrete steps can be undertaken to rethink partnerships. This goes hand in hand with reconceptualizing global health as an academic discipline, mainly through being explicit about past and present inequalities between Northern and Southern universities that this discipline has thus far eluded. Authentic and transformative partnerships are vital to overcome the one-sided nature of many partnerships that can provide a breeding-ground for inequality.

TL;DR: It is indicated that IL-alpha and TNF-alpha increase PDGF-AA binding and activity for osteoblasts by mechanisms that are at least in part independent of new receptor synthesis, and regulatory events that could control how PDGF binding sites specifically recognize different ligands are suggested.
Abstract: In osteoblast-enriched cultures from fetal rat bone, the A-chain homodimer of platelet-derived growth factor (PDGF-AA) is less potent than the PDGF isoforms containing B chain subunits (PDGF-AB and PDGF-BB), but normal osteoblasts appear to synthesize only PDGF-A subunit mRNA and polypeptide. However, other agents may regulate PDGF-AA activity in skeletal tissue. Pretreatment of osteoblast-enriched cultures with interleukin 1 alpha (IL-1 alpha) or tumor necrosis factor-alpha (TNF-alpha) synergistically enhanced the mitogenic effect of PDGF-AA coincident with increased binding site occupancy, but neither factor augmented PDGF-BB activity or binding. Polyacrylamide gel analysis showed 125I-PDGF-AA binding complexes predominantly at greater than 200 kD and faint labeling at 185 kD. After IL-1 alpha or TNF-alpha pretreatment, PDGF-AA binding increased at both sites, but this effect was more striking at 185 kD, which co-migrated with 125I-PDGF-BB-labeled complexes. PDGF-AA binding sites were rapidly lost by comparison to those for PDGF-BB in cycloheximide-treated cultures, but they remained relatively enhanced by IL-1 alpha and TNF-alpha pretreatment. These studies indicate that IL-alpha and TNF-alpha increase PDGF-AA binding and activity for osteoblasts by mechanisms that are at least in part independent of new receptor synthesis, and suggest regulatory events that could control how PDGF binding sites specifically recognize different ligands.

TL;DR: This contemporary cohort of US patients confirms that TAVI results in cerebral infarction in most patients and that 1 in 5 patients have measurable neurologic impairment and 1 in 3 patients have decrease in cognitive measures by Montreal Cognitive Assessment score after TAVi, reinforcing the need for methods to mitigate the risk of brain injury during T AVI.
Abstract: Cerebral embolization during transcatheter aortic valve implantation (TAVI) can lead to a spectrum of clinically relevant manifestations, ranging from overt stroke to mild neurologic or cognitive deficits and subclinical cerebral infarcts. This study sought to determine the frequency of neurologic injury, cerebral ischemic lesions, and cognitive dysfunction in subjects undergoing contemporary commercial TAVI in the United States. Neuro-TAVR is the first prospective, multicenter study to use serial systematic neurologic and cognitive assessments and diffusion-weighted magnetic resonance imaging (at 4 ± 2 days after procedure) to investigate the incidence and severity of neurologic injury after contemporary unprotected TAVI in the United States. A total of 44 consecutive patients underwent TAVI at 5 US sites. Diffusion-weighted magnetic resonance imaging lesions were detected in 94%, with a mean of 10.4 ± 15.3 lesions per subject and a median total lesion volume of 295 mm 3 (interquartile range 71.6 to 799.6 mm 3 ). New neurologic impairment (worsening in National Institutes of Health Stroke Scale score from baseline with new cerebral lesions) occurred in 22.6% (7 of 31) of subjects at discharge and 14.8% (4 of 27) at 30 days. In addition, cognitive decrements from baseline were identified by the Montreal Cognitive Assessment in 33% (12 of 36) of subjects at discharge and 41% (13 of 32) at 30 days. In conclusion, this contemporary cohort of US patients confirms that TAVI results in cerebral infarction in most patients and that 1 in 5 patients have measurable neurologic impairment and 1 in 3 patients have decrease in cognitive measures by Montreal Cognitive Assessment score after TAVI, reinforcing the need for methods to mitigate the risk of brain injury during TAVI.

TL;DR: Despite a decrease in the number of MVCs and VMT, the crash rate of single vehicles increased post stay-at-home order enactment in Connecticut after accounting for reductions in VMT.
Abstract: Introduction Understanding how the COVID-19 pandemic has impacted our health and safety is imperative. This study sought to examine the impact of COVID-19’s stay-at-home order on daily vehicle miles travelled (VMT) and MVCs in Connecticut. Methods Using an interrupted time series design, we analysed daily VMT and MVCs stratified by crash severity and number of vehicles involved from 1 January to 30 April 2017, 2018, 2019 and 2020. MVC data were collected from the Connecticut Crash Data Repository; daily VMT estimates were obtained from StreetLight Insight’s database. We used segmented Poisson regression models, controlling for daily temperature and daily precipitation. Results The mean daily VMT significantly decreased 43% in the post stay-at-home period in 2020. While the mean daily counts of crashes decreased in 2020 after the stay-at-home order was enacted, several types of crash rates increased after accounting for the VMT reductions. Single vehicle crash rates significantly increased 2.29 times, and specifically single vehicle fatal crash rates significantly increased 4.10 times when comparing the pre-stay-at-home and post-stay-at-home periods. Discussion Despite a decrease in the number of MVCs and VMT, the crash rate of single vehicles increased post stay-at-home order enactment in Connecticut after accounting for reductions in VMT.
