INTRODUCTION: Children increasingly are being seen in the emergency department for a concussion, or mild traumatic brain injury (mTBI). A key aim of the ED visit is to provide discharge advice that can help parents to identify an evolving neurosurgical crisis, facilitate recovery, and prevent reinjury. The present study examined parents' knowledge of symptoms and recall of discharge instructions after their adolescent's mTBI and the effect of supplementing written discharge instructions with verbal instruction and reinforcement...

Interconnected LiCuVO4 networks were synthesized through a facile surfactant-assisted approach. Detailed investigations on the lithium storage mechanism manifest that metallic Cu nanoparticles are generated in situ during the first discharge process and remain mostly intact in the following cycles, thereby enhancing conductivity of the electrode. The interconnected networks with submicron sized primary particles endow the LiCuVO4 with a large amount of active sites and thus high capacitive charge storage. Benefiting from a peculiar structure, the resultant interconnected LiCuVO4 networks deliver extraordinary rate performance (216 mA h g(-1) up to 10 A g(-1)) and ultralong cycling stability (∼85% capacity retention after 5000 cycles at 5 A g(-1))...

Electric field tuning of magnetism is one of the most intensely pursued research topics of recent times aiming at the development of new-generation low-power spintronics and microelectronics. However, a reversible magnetoelectric effect with an on/off ratio suitable for easy and precise device operation is yet to be achieved. Here we propose a novel route to robustly tune magnetism via the charging/discharging processes of hybrid supercapacitors, which involve electrostatic (electric-double-layer capacitance) and electrochemical (pseudocapacitance) doping...

The role of lithium salts in determining the discharge capacity of Li-O2 batteries has been highlighted in several recent studies, however, questions pertaining to their effect on the cathode surface and in the solution phase still remain unanswered. We conducted galvanostatic discharge experiments with different compositions of a binary mixture of 1M of LiNO3 and LiTFSI in tetraglyme (TEGDME) as the electrolyte and analyzed the discharge products using techniques such as FT-IR, Raman Spectroscopy and SEM. It was observed that there is a non-linear correlation between the electrolyte composition and the first discharge capacity, with the highest discharge capacity achieved with the electrolyte composition as 0...

Nickel hydroxide (Ni(OH)2) has drawn intense research interest due to its high theoretical specific capacitance as one of the promising next generation electrode materials for supercapacitors, however, the practical applications of Ni(OH)2 is hindered by its lower cycling life. To overcome the inherent defects, herein we demonstrate a unique interconnect honeycomb structure of g-C3N4 and Ni(OH)2 synthesized by an environmental-friendly one-step method. In this work, g-C3N4 support a perpendicular charge transporting direction in charge-discharge process, which is beneficial for electron diffusion...

Cobalt hydroxide is a promising electrode material for supercapacitors due to the high capacitance and long cyclability. However, the energy storage/conversion mechanism of cobalt hydroxide is still vague at the atomic level. Here we shed light on how cobalt hydroxide functions as a supercapacitor electrode at operando conditions. We find that the high specific capacitance and long cycling life of cobalt hydroxide involve a complete modification of the electrode morphology, which is usually believed to be unfavourable but in fact has little influence on the performance...

Three-dimensional nanoporous carbon frameworks encapsulated Sn nanoparticles (Sn@3D-NPC) are developed by a facile method as an improved lithium ion battery anode. The Sn@3D-NPC delivers a reversible capacity of 740 mAh g(-1) after 200 cycles at a current density of 200 mA g(-1), corresponding to a capacity retention of 85% (against the second capacity) and high rate capability (300 mAh g(-1) at 5 A g(-1)). Compared to the Sn nanoparticles (SnNPs), such improvements are attributed to the 3D porous and conductive framework...

A hierarchical mesoporous carbon foam (ECF) with an interconnected micro-/mesoporous architecture was prepared and used as a binder-free, low-cost, high-performance anode for lithium ion batteries. Due to its high specific surface area (980.6 m(2)/g), high porosity (99.6%), light weight (5 mg/cm(3)) and narrow pore size distribution (~2 to 5 nm), the ECF anode exhibited a high reversible specific capacity of 455 mAh/g. Experimental results also demonstrated that the anode thickness significantly influence the specific capacity of the battery...

OBJECTIVES: Patients are 30% less likely to be readmitted or visit the emergency department if they have a clear understanding of their discharge instructions. A standardized approach to a hospital discharge plan has not been universally implemented, however. Our goal was to increase patients' comprehension of discharge instructions by implementing a standardized patient-centered discharge planning protocol that uses a physician team member to explain these plans. METHODS: This was a prospective study that included all of the patients discharged from an inpatient medical teaching service in a community-based hospital during the study period...

OBJECTIVES: Healthcare expenditures in the United States have increased exponentially and hospital care accounts for one-third of these costs. Approximately 18% of hospitalized Medicare beneficiaries are being readmitted to the hospital within 30 days. Engaging patients in the discharge process can help better identify patients' postdischarge needs and implement more effective readmission prevention strategies. The objective of our study was to identify the factors that contribute to hospital readmission as seen from patients' perspectives in a large urban community hospital...

INTRODUCTION: Patients transitioning from the hospital to a skilled nursing home (SNF) are susceptible to medication-related errors resulting from fragmented communication between facilities. Through continuous process improvement efforts at the hospital, a targeted needs assessment was performed to understand the extent of medication-related issues when patients transition from the hospital into a SNF, and the gaps between the hospital's discharge process, and the needs of the SNF and long-term care (LTC) pharmacy...

Sodium ion batteries (SIBs) are considered one of the most promising alternatives for large-scale energy storage due largely to the abundance and low cost of sodium. However, the lack of high-performance cathode materials at low cost represents a major obstacle toward broad commercialization of SIB technology. In this work, we report a green route strategy that allows cost-effective fabrication of carbon-coated Na2FePO4F cathode for SIBs. By using vitamin C as a green organic carbon source and environmentally friendly water-based polyacrylic latex as the binder, we have demonstrated that the Na2FePO4F phase in the as-derived Na2FePO4F/C electrode shows a high reversible capacity of 117 mAh g(-1) at a cycling rate of 0...

When patients are transferred from the hospital to other health care settings, responsibility for the patient is transferred from the treating physician, nurse, paramedic or pharmacist at the hospital to the next health care provider. Good patient handovers from hospital to other healthcare settings are essential to ensure continuity of care. However, handovers are often delayed or incomplete and the patient is barely involved in her or his own transfer. Risks related to an incomplete handover may be considerable...

A facile process is developed to prepare SnO2-based composites through using metal-organic frameworks (MOFs) as precursors. The nitrogen-doped graphene wrapped okra-like SnO2 composites (SnO2@N-RGO) are successfully synthesized for the first time by using Sn-based metal-organic frameworks (Sn-MOF) as precursors. When utilized as an anode material for lithium-ion batteries, the SnO2@N-RGO composites possess a remarkably superior reversible capacity of 1041 mA h g(-1) at a constant current of 200 mA g(-1) after 180 charge-discharge processes and excellent rate capability...

BACKGROUND: Evidence indicates that suboptimal clinical handover from the intensive care unit (ICU) to general wards leads to unnecessary ICU readmissions and increased mortality. We aimed to gain insight into barriers and facilitators to implement and use ICU discharge practices. METHODS: A mixed methods approach was conducted, using 1) 23 individual and four focus group interviews, with post-ICU patients, ICU managers, and nurses and physicians working in the ICU or general ward of ten Dutch hospitals, and 2) a questionnaire survey, which contained 27 statements derived from the interviews, and was completed by 166 ICU physicians (21...

Recently sodium ion batteries (SIBs) as a new energy storage system have attracted enormous interests. Unfortunately, the development of high-performance electrode materials for SIBs is restricted owing to the large volume change during sodium insertion and extraction. In this work, porous CoFe2O4 nanocubes (PCFO-NCs) were prepared simply by annealing metal-organic frameworks and used as anode materials for SIBs. The PCFO-NCs exhibit a high initial Coulombic efficiency of 68.8% and a maximum reversible capacity of 360mAhg(-1) after 50 cycles at the current density of 50mAg(-1), as well as good rate capability and excellent cycling stability at high current density...

Co9 S8 is considered a promising candidate as the anode material in lithium-ion batteries (LIBs) because of its remarkable electrical conductivity, high theoretical capacity, and low cost. However, the practical application of Co9 S8 is greatly restricted because of its poor cycling stability and rate performance, which result mainly from the large volume expansion and dissolution of the polysulfide intermediates during the charge/discharge process. In this report, Co9 S8 embedded in N-rich carbon hollow spheres are successfully designed and synthesized through an in situ pyrolysis and sulfurization process, employing the well-known ZIF-67 as the precursor and ethanethiol as the sulfur source...
