Global point-of-care ultrasound education and training in the age of COVID-19.

The COVID-19 pandemic has disrupted traditional global point-of-care ultrasound (POCUS) education and training, as a result of travel restrictions. It has also provided an opportunity for innovation using a virtual platform. Tele-ultrasound and video-conferencing are alternative and supportive tools to augment global POCUS education and training. There is a need to support learners and experts to ensure that maximum benefit is gained from the use of these innovative modalities

The incidence of deep vein thrombosis detected by routine surveillance ultrasound in neurosurgery patients receiving dual modality prophylaxis.

The optimal method of thromboprophylaxis and the value of screening ultrasonography for detection of deep venous thrombosis (DVT) in neurosurgery patients remains unclear. The goal of this study was to determine the incidence of DVT in neurosurgical patients who, by hospital protocol, receive surveillance ultrasonography of the lower extremities twice weekly, in addition to prophylaxis with unfractionated heparin and external pneumatic compression sleeves. A retrospective review of 7,298 ultrasound studies carried out on 2,593 patients over 4 years at a university neurosurgical hospital was conducted. There was a 7.4% incidence of proximal lower extremity DVT and a 9.7% total incidence including distal DVT. A greater number of distal DVTs were detected with the implementation of whole-leg ultrasonography in the last 2 years of observation. Chart review of 237 patients diagnosed with DVT demonstrated an admitting diagnosis of subarachnoid hemorrhage in nearly half of the patients. The median hospital length of stay for DVT patients was 18 days. Institutional control data demonstrated non-ruptured aneurysm and cerebrovascular anomalies to be the leading reason for admission, followed closely by subarachnoid hemorrhage. The hospital protocol of biweekly screening ultrasound and dual modality prophylaxis for neurosurgery patients resulted in a proximal DVT incidence consistent with that demonstrated by previous studies of standardized dual modality prophylaxis, and higher than that demonstrated in previous studies that employed ultrasound screening protocols

Changing The Playbook For Immigrant Health

Philadelphia’s response to welcoming Afghan evacuees during the COVID-19 pandemic suggests the need for a new approach to immigrant health care

The logics of invited and uninvited material participation: bringing blood pressure self-monitoring into the clinic

This paper addresses debates concerning the ‘participatory turn’ in healthcare. It focuses on the case of blood pressure self-monitoring, understanding this as a form of patient participation at the level of individual care. Drawing and expanding on the work of Marres and Wynne and their notions of material participation and of uninvited engagement, we examine how patients’ home blood pressure self-monitoring is incorporated into clinical care, how the materials of blood pressure self-monitoring mediate participation and how we might characterise the practices of participation found within everyday clinical care. Our analysis makes new conceptual links, suggesting that, in this context, invited participation appears to align with participation made easy, while uninvited participation involves more invested, more engaged participation. We offer two further developments of these concepts. First, we trouble characterisations of invited and uninvited participation as distinct and separate, observing movement between these. Second, through applying the logics of material participation in a new context, everyday clinical practice, we suggest that the logic of participation made easy might be extended beyond lay people, to apply to professionals as well. Our analysis illustrates how materials are mobilised to facilitate invited and uninvited participation within the context of the on-going asymmetries in doctor patient relationships

Capital Fixity and Mobility in Response to the 2008-09 Crisis: Variegated Neoliberalism in Mexico and Turkey

The article examines the 2008-9 crisis responses in Mexico and Turkey as examples of variegated neoliberalism. The simultaneous interests of corporations and banks relative to the national fixing of capital and their mobility in the form of global investment heavily influenced each state authority’s policy responses to the crisis at the expense of the interests of the poor, workers, and peasantry. Rather than pitching this as either evidence of persistent national differentiation or some Keynesian state resurgence, we argue from a historical materialist geographical framework that the responses of capital and state authorities in Mexico and Turkey actively constitute and reconstitute the global parameters of market regulatory design and neoliberal class rule through each state’s distinct domestic policy formation and crisis management processes. While differing in specific content the form of Mexico and Turkey’s state responses to the crisis ensured continuity in their foregoing neoliberal strategies of development and capital accumulation, most notably in the continued oppression of workers. That is, the prevailing strategy of accumulation continues to be variegated neoliberalism

Molecular phylogenetics reveals a new species of Prostanthera from tropical Queensland with links to more southerly taxa

Prostanthera eungella B.J.Conn & K.M.Proft (Lamiaceae) is described as a new species from the South Kennedy botanical region of northern Queensland. Concatenated nuclear (ETS) and chloroplast (trnH–psbA) sequence data for 38 species of Prostanthera were analysed using maximum-likelihood and Bayesian-inference methods. These combined data recovered P. eungella as part of a polytomy that included P. galbraithiae, P. howelliae¸ and a P. tallowa + P. lasianthos clade. A detailed description, photograph of holotype specimen, and distribution map of P. eungella are provided
