Exceptionally High, Strongly Temperature Dependent, Spin Hall Conductivity of SrRuO.

Spin-orbit torques (SOT) in thin film heterostructures originate from strong spin-orbit interactions (SOI) that, in the bulk, generate a spin current due either to extrinsic spin-dependent, skew, or/and side-jump scattering or to intrinsic Berry curvature in the conduction bands. While most SOT studies have focused on materials with heavy metal components, the oxide perovskite SrRuO has been predicted to have a pronounced Berry curvature. Through quantification of its spin current by the SOT exerted on an adjacent Co ferromagnetic layer, we determine that SrRuO has a strongly temperature ( T)-dependent spin Hall conductivity σ , increasing with the electrical conductivity, consistent with expected behavior of the intrinsic effect in the "dirty metal" regime.

Safety and Pharmacokinetics of Levobupivacaine Following Fascia Iliaca Compartment Block in Elderly Patients.

Background: Fascia iliaca compartment block (FICB) is an increasingly popular analgesic technique in elderly patients with hip fracture. Despite requiring large volumes of local anaesthetic, there are no plasma pharmacokinetic data on FICB in elderly patients.

Objectives: The objective of this study was to determine the pharmacokinetic profile of a levobupivacaine 75 mg (30 mL 0.

Loperamide induced cardiac arrhythmia successfully supported with veno-arterial ECMO (VA-ECMO), molecular adsorbent recirculating system (MARS) and continuous renal replacement therapy (CRRT).

This case of Loperamide misuse had refractory ventricular arrhythmias and was successfully supported by VA ECMO. Loperamide is currently available without prescription and can be obtained in large quantities over the internet despite Food and Drug Administration (FDA) 2016 black box warning noting cardiac toxicity. This case illustrates the life-threatening toxicity of loperamide and suggests a supportive modality to provide clinical time while the drug is cleared endogenously or exogenously.

Current-Induced Torques with Dresselhaus Symmetry Due to Resistance Anisotropy in 2D Materials.

We report measurements of current-induced torques in heterostructures of Permalloy (Py) with TaTe, a transition-metal dichalcogenide (TMD) material possessing low crystal symmetry, and observe a torque component with Dresselhaus symmetry. We suggest that the dominant mechanism for this Dresselhaus component is not a spin-orbit torque but rather the Oersted field arising from a component of current that flows perpendicular to the applied voltage due to resistance anisotropy within the TaTe. This type of transverse current is not present in wires made from a single uniform layer of a material with resistance anisotropy but will result whenever a material with resistance anisotropy is integrated into a heterostructure with materials having different resistivities, thereby producing a spatially nonuniform pattern of current flow.

Analyzing Spatial Learning and Prosocial Behavior in Mice Using the Barnes Maze and Damsel-in-Distress Paradigms.

The Barnes maze is a reliable measure of spatial learning and memory that does not require food restriction or exposure to extremely stressful stimuli. The Barnes maze can also assess other mouse behaviors, such as general motivation to escape from the maze platform and exploratory behavior. The Barnes maze can measure whether a genetic mutation or environmental variable can impact the acquisition and retention of spatial memories, as well as provide information about the search strategy employed by the mice.

Spin-Orbit Torques in NbSe/Permalloy Bilayers.

We present measurements of current-induced spin-orbit torques generated by NbSe, a fully metallic transition-metal dichalcogenide material, made using the spin-torque ferromagnetic resonance (ST-FMR) technique with NbSe/Permalloy bilayers. In addition to the out-of-plane Oersted torque expected from current flow in the metallic NbSe layer, we also observe an in-plane antidamping torque with torque conductivity σ ≈ 10 (ℏ/2e)(Ωm) and indications of a weak field-like contribution to the out-of-plane torque oriented opposite to the Oersted torque. Furthermore, in some samples we also measure an in-plane field-like torque with the form m̂ × ẑ, where m̂ is the Permalloy magnetization direction and ẑ is perpendicular to the sample plane.

Impact of Ketamine Use on Adjunctive Analgesic and Sedative Medications in Critically Ill Trauma Patients.

Background: Ketamine may be used to manage pain and agitation that is refractory to what are usually considered traditional agents such as fentanyl, propofol, benzodiazepines, and dexmedetomidine; however, literature describing the use of ketamine continuous infusions for this purpose in critically ill trauma patients is limited.

Objectives: The primary objective of this study was to determine the impact of the initiation of a ketamine continuous infusion on sedative and analgesic use in critically ill trauma patients. Secondary objectives were to identify the patient population in which ketamine was initiated, assess the proportion of time patients were at their goal level of sedation, and determine the dosing patterns of adjunctive sedative agents.

Telehealth Support of Managed Care for a Correctional System: The Open Architecture Telehealth Model.

Introduction: The intent was to evaluate time to match initial investment of a new, statewide correctional system telehealth program based upon cumulative savings by avoidance of transportation and custody-related costs.

Materials And Methods: The setting was a statewide correctional system where prisoners received medical care through enhanced telemedicine technology supported by newly recruited specialty providers delivered through an open architecture system. The patients were incarcerated persons requiring nonemergent consultations in 10 specialties.

Options for tele-intensive care unit design: centralized versus decentralized and other considerations: it is not just a "another black sedan".

This article seeks assist physicians or administrators considering establishing a Tele-ICU. Owing to an apparent domination of the Tele-ICU field by a single vendor, some may believe that there is only one design option. In fact, there are many alternative design formats that do not require the consumer to possess high-level technical expertise.

Critical care telemedicine: evolution and state of the art.

Objectives: To review the growth and current penetration of ICU telemedicine programs, association with outcomes, studies of their impact on medical education, associations with medicolegal risks, identify program revenue sources and costs, regulatory aspects, and the ICU telemedicine research agenda.

Data Sources: Review of the published medical literature, governmental documents, and opinions of experts from the Society of Critical Care Medicine ICU Telemedicine Committee.

Data Synthesis: Formal ICU telemedicine programs now support 11% of nonfederal hospital critically ill adult patients.

Different systems and formats for tele-ICU coverage: designing a tele-ICU system to optimize functionality and investment.

Technology always changes, yet change or evolution within the tele-ICU has been slow. In developing a modern telemedicine system to manage acute illness, there are several concepts the developer/administrator should consider to include "scalability," centralized/decentralized systems, open/closed architecture, inclusivity of the medical community, mobile technology, price set, and governmental regulation. The intent of this manuscript is to apply these concepts to current tele-ICU technology, explain the concepts in some depth, and finally, to speculate as to how the future tele-ICU might look.

Utilization of robotic "remote presence" technology within North American intensive care units.

Objective: To describe remote presence robotic utilization and examine perceived physician impact upon care in the intensive care unit (ICU).

Study Design: Data were obtained from academic, university, community, and rural medical facilities in North America with remote presence robots used in ICUs. Objective utilization data were extracted from a continuous monitoring system.

A working lexicon for the tele-intensive care unit: we need to define tele-intensive care unit to grow and understand it.

Telemedicine in the intensive care unit (Tele-ICU) has grown exponentially since the first formalized program in 2000. Initially, there was limited product choice, and certain capabilities have been engineered into the process with the implication of necessity. New technology is evolving, and new vendors are entering the market place, which should yield a multitude of technologies from which to select.

The tele-intensive care unit during a disaster: seamless transition from routine operations to disaster mode.

Disaster plans, during the actual disaster, often do not function as conceived and designed. Disaster or emergency situations may not present as anticipated in planning sessions confounding the intent of disaster planners. Systems that are created and shelved awaiting the disaster may be dysfunctional when needed due to problems such as failed batteries, forgotten training, misplaced equipment, the retraining curve, or software that has not been updated.

[Open and laparoscopic transhiatal oesophagectomy for cancer of the oesophagus: analysis of resection margins and lymph nodes].

Introduction: Surgical treatment of cancer of the oesophagus is associated with a high morbidity and mortality. Minimally invasive surgery has been proposed as an alternative to try to reduce these complications; however, at this time there are not many studies that evaluate the oncological validity of this method. The objective of this work is to give a preliminary audit of the results of our experience in both surgical techniques, with special emphasis on the oncopathological aspects (resection margins and lymph nodes).

Interhospital transport of the adult mechanically ventilated patient.

Interhospital transport of the adult mechanically ventilated patient may be necessary for those who require specialized care. An experienced medical team can safely transport even the most critically ill patients if the care is optimized before departure. Patients with severe respiratory failure may have to remain on an ICU ventilator throughout the transport period, depending on the specific transport ventilator.

Magnesium, calcium, zinc, and nitrogen loss in trauma patients during continuous renal replacement therapy.

Background: Whether standard nutrition support is sufficient to compensate for mineral loss during continuous renal replacement therapy (CRRT) is not known.

Methods: Adult men with traumatic injuries were recruited; one-half of recruits required CRRT for acute renal failure. All urine and effluent (from CRRT) were collected for 72 hours.
