There is interest in methods of measuring noninvasive intracranial pressure (ICP), including pupillometry, ultrasonographic transcranial Doppler (TCD), and optic nerve sheath diameter (ONSD), for diagnosing traumatic brain injury (TBI) in limited resource environments. Whether these technologies have diagnostic agreement is unknown. We hypothesized that ONSD, pupillometry, and TCD could both distinguish severe TBI and correlate with ICP.

A prospective study of 135 patients was conducted at a level 1 trauma center. Four test groups were established nontrauma patients with ICP monitoring, trauma patients without TBI, trauma patients with mild TBI, and trauma patients with severe TBI with ICP monitoring. All patients underwent daily measurements of ONSD, pupillometry, and TCD with both CX50 Sonosite and the Spencer ST3 Yi Pencil probe.

ONSD differed significantly in patients with severe TBI compared with patients with mild and no TBI, but did not correlate with ICP. Pupillometric constriction velocity, dilation velocity, and percent change in pupil diameter were significantly different in patients with severe TBI, but also did not correlate with ICP. TCD did not differ among TBI severities, but middle cerebral artery peak systolic velocity, middle cerebral artery flow velocity, and carotid flow velocity correlated with ICP.

This is a novel study of four noninvasive tests to screen for severity of TBI and measure ICP. Our analysis indicates that no single device can do both. However, ONSD and pupillometry may be used as a supplementary screening tool for severe TBI, whereas TCD could be used to estimate and follow ICP in patients with severe TBI.

This paper compares patients' reported use of the internet with matched video recordings of consultations. The concepts of doctorability and epistemics are employed to consider similarities and differences between patients' reports in interviews and actions in the consultation. Data are drawn from the Harnessing Resources from the Internet study conducted in the UK. The data set consists of 281 video-recorded general practice consultations, with pre-consultation questionnaires completed by all patients, interviews with all 10 participating doctors and 28 selected patients. We focus on the 28 patient interviews and associated consultation recordings. A conversation analytic (CA) approach is used to systematically inspect both the interview and consultation data. In interviews patients presented use of the internet as associated with appropriate self-management and help-seeking. In consultations patients skilfully translated what they had found on the internet in order to provide grounds for the actions they sought. We conclude that patients translate and utilise what they have found on the internet to assert the doctorability of their presenting problems. Furthermore, patients design their talk in both interviews and consultations to accord with their understanding of the epistemic rights of both doctors and patients. Patients search the internet so they are informed about their medical problem, however they carefully manage disclosure of information to avoid disrupting the smooth running of medical interactions.The concept of environmental repossession responds to a global movement led by Indigenous peoples to reclaim their territories and ways of life. As Indigenous wellness is intimately tied to relationships to land, processes of environmental repossession are a means to revitalize knowledge systems, identities and relationships that foster strong and healthy communities. Due to historic and ongoing forces of dispossession, the Anishinaabe community of Biigtigong Nishnaabeg has experienced limited access to Mountain Lake, a culturally and historically significant place in their ancestral territory. In the summer of 2018, the Chief and Council of Biigtigong constructed two cabins along the shores of Mountain Lake for community use and, one year later, hosted a week-long camp to bring Elders, youth and band staff together in this place. Drawing from 15 in-depth interviews with participating community members, this study documented the planning and implementation of the cabins and camp at Mountain Lake and examined the community meanings of this process. Tanespimycin mw The findings suggest that the cabins and camp functioned as a local process of environmental repossession through multiple and interconnected steps to reclaim access to Mountain Lake, reintroduce the community to this place and begin remaking community relationships to this land. As Indigenous communities globally seek to reclaim their territories and rights to land, this article speaks to the tensions of this work and the structures that support its practice locally.The link between workers with sickle cell disorder (SCD) and employment has until now been seen through the lens of the person's disease, not their relationship to work (paid and unpaid). Using SCD as a case study, we foreground relations of employment, setting sickle cell and work into ecological context. In 2018, two focus group discussions and 47 depth-interviews were conducted with black disabled workers living with SCD across England. The relational concepts of Anna Tsing (2015) - salvage accumulation, entanglement and precarity - were used as an analytical framework to assess the reported experiences. To understand the experiences of those with SCD and employment, it is necessary to apprehend the whole ecology of their bonds to their bodies; their social relationships of kin and family; and their wider social relations to communities. Paid employment breaks bonds crucial to those living with SCD. First, employers can only extract sufficient productive value from workers if they disregard the necessary self-care of a precarious body.
