Abstract

Marine biota are redistributing at a rapid pace in response to climate change and shifting seascapes. While changes in fish populations and community structure threaten the sustainability of fisheries, our capacity to adapt by tracking and projecting marine species remains a challenge due to data discontinuities in biological observations, lack of data availability, and mismatch between data and real species distributions. To assess the extent of this challenge, we review the global status and accessibility of ongoing scientific bottom trawl surveys. In total, we gathered metadata for 283,925 samples from 95 surveys conducted regularly from 2001 to 2019. We identified that 59% of the metadata collected are not publicly available, highlighting that the availability of data is the most important challenge to assess species redistributions under global climate change. Given that the primary purpose of surveys is to provide independent data to inform stock assessment of commercially important populations, we further highlight that single surveys do not cover the full range of the main commercial demersal fish species. An average of 18 surveys is needed to cover at least 50% of species ranges, demonstrating the importance of combining multiple surveys to evaluate species range shifts. We assess the potential for combining surveys to track transboundary species redistributions and show that differences in sampling schemes and inconsistency in sampling can be overcome with spatio-temporal modeling to follow species density redistributions. In light of our global assessment, we establish a framework for improving the management and conservation of transboundary and migrating marine demersal species. We provide directions to improve data availability and encourage countries to share survey data, to assess species vulnerabilities, and to support management adaptation in a time of climate-driven ocean changes.

Abstract

Background: Good outcomes in stroke care require swift diagnostics, for which magnetic resonance imaging (MRI) as first-line brain imaging is superior to computed tomography scans. Reduced length of stay (LOS) in hospital and emergency departments (ED) may optimize resource use. Fast-track stroke MRI was implemented as the primary imaging technique for suspected stroke, in the ED at Copenhagen University Hospital—Herlev and Gentofte in 2020. Objectives: We aimed to describe and compare LOS, MRI utilization, and the rate of strokes versus stroke-mimicking conditions on the stroke ward, before and after the implementation of fast-track MRI. Design and method: In this cross-sectional study, we used data from admissions to the neurologic ED and associated non-comprehensive stroke unit. We compared two time periods, that is, January 1–December 31, 2019, and January 1–December 31, 2020, before and after the implementation of fast-track stroke MRI. Results: There were 6650 admissions before and 7201 after implementation of fast-track stroke MRI. After implementation, we observed reductions in average LOS in hospitals from 56.0 to 38.6 h (p < 0.001), and LOS in ED from 9.17 to 8.63 h (p < 0.001). The use of inpatient MRI increased significantly, and the rate of acute ischemic stroke patients on the ward increased yet the rate of non-strokes remained unchanged. The association between shorter admissions and access to MRI remained (odds ratio 1.81, p < 0.001), after adjusting for sex, age, weekend admissions, and lockdown periods. Conclusion: Fast-track stroke MRI in ED associated with reduced LOS in hospital. Plain language summary: Emergency department logistics after implementation of magnetic resonance brain scans, as a first-line imaging technique, for suspected stroke Why was the study done? Swift diagnostics is essential, as stroke treatment is time sensitive. Brain imaging is a substantial part of stroke workups, as it allows doctors to distinguish blood clots from brain hemorrhages. Occasionally, imaging is a bottle neck ahead of treatment. Traditionally, CT (computed tomography) has been used in stroke care, but MRI (magnetic resonance imaging) is diagnostically superior, as it helps visualize brain tissue affected by a clot, even very early on. However, MRI is more time consuming than CT. I.e., for stroke imaging, not only the type of scan is of interest, but also associated logistics. What did the researchers do? We evaluated the change in hospital logistics, associated with a change in our first-line imaging technique for stroke - from CT in 2019 to MRI in 2020. We measured lengths of stay, both in hospital overall, and in the emergency department, rates of readmissions, and what diagnoses our patients had, when they were discharged after a full workup on the stroke ward (i.e., either a stroke, or something that mimics a stroke). What did the researchers find? Out of 13851 admissions, 6550 were admitted in 2019, when CT was the initial imaging technique, and 7201 in 2020, after MRI-first had been implemented. We observed a reduction in the average length of stay in hospital, from 56 hours before MRI-first and 38 hours after. The average length of stay in the emergency department also changed from 9.1 to 8.6 hours, after MRI implementation. The rate of readmission to the emergency department remained unchanged. Additionally, the rate of patients with strokes admitted to the stroke ward increased, indicating that we could identify stroke-mimicking conditions prior to admission. What do the findings mean? Implementing an MRI-first approach for suspected stroke, allowed us to improve our logistics, both on the stroke-ward, but also in the emergency department, whilst maintaining diagnostic accuracy.

Abstract

Objectives: In Denmark, the use of bicycles is widespread, and head injuries are often seen in cyclists involved in collisions. Despite the well-known effects of using a helmet to reduce head injuries, using helmets is not mandatory in Denmark. The primary objective of this study was to provide data regarding injury outcomes and helmet usage. Methods: Participants were bicyclists who sustained head injuries in bicycle collisions and were assessed by the Copenhagen Emergency Medical Services between 1 January 2016; and 15 June 2019. Patients with suspected head injury were identified in an electronic prehospital patient record. Data were linked to the Danish National Patient Registry to retrieve the diagnosis and were categorized into head injury or no head injury based on the diagnosis. Adjusted logistic regression analyses were reported with odds ratios and corresponding confidence intervals to assess the risk of head injury while adjusting for risk factors like age, sex, alcohol consumption, occurrence during weekends and traumatic brain injury. Results: A total of 407 patients were included in this study. Within this entity, 247 (61%) had sustained a head injury. The use of a helmet was reported in one-third of the included patients. Among the head-injured patients, 13% sustained moderate to severe head injuries. Patients with suspected alcohol involvement were significantly less likely to report the use of a helmet. Helmet use reduced the risk of head injury with an odds ratio of 0.52, (95% CI 0.31 − 0.86). In high-energy trauma, the use of a helmet showed a significant reduction in the risk of sustaining a head injury with an odds ratio of 0.28, (95% CI 0.12 − 0.80). Conclusions: In this study, using a helmet was associated with a significantly decreased risk of head injury; this association was even more significant in high-energy trauma. [ABSTRACT FROM AUTHOR]
