Considerations across multiple stakeholder groups when implementing fall prevention programs in the acute hospital setting: a qualitative study.

Background: Falls in hospital remain a common and costly patient safety issue internationally. There is evidence that falls in hospitals can be prevented by multifactorial programs and by education for patients and staff, but these are often not routinely or effectively implemented in practice. Perspectives of multiple key stakeholder groups could inform implementation of fall prevention strategies.

High Dielectric Transparent Film Tailored by Acceptor and Donor Codoping.

High dielectric constant materials are of particular current interests as indispensable components in transistors, capacitors, etc. In this context, there are emerging trends to exploit defect engineering in dielectric ceramics for enhancing the performance. However, demonstrations of similar high dielectric performance in integration-compatible crystalline films are rare.

Higher-Order Multiphoton Absorption Upconversion Lasing Based on ZnO/ZnMgO Multiple Quantum Wells.

In the progress of nonlinear optics, multiphoton absorption (MPA) upconversion lasing enables many vital applications in bioimaging, three-dimensional optical data storage, and photodynamic therapy. Here, efficient four-photon absorption upconversion lasing from the ZnO/ZnMgO multiple quantum wells (MQWs) at room temperature is realized. Moreover, the MPA upconversion lasing and third-harmonic generation peak generated in the MQWs under the excitation of a femtosecond (fs) laser pulse were observed concurrently, and the essential differences between each other were studied comprehensively.

Shape-control growth of 2D-InSe with out-of-plane ferroelectricity by chemical vapor deposition.

For potential applications in ferroelectric switching and piezoelectric nano-generator devices, the promising ferroelectric properties of two dimensional (2D) layered In2Se3 attracted much attention. In the present study, 2D In2Se3 flakes down to monolayers are grown by the chemical vapor deposition (CVD) technique on a mica substrate with their structural, optical and ferroelectric properties being studied. The effect of growth parameters (time of growth and Ar flow rate) on the shape and size of the deposited flakes was studied.

Challenges, Learning Curve, and Safety of Endoscopic Endonasal Surgery of Sellar-Suprasellar Lesions in a Community Hospital.

Background And Objective: Endoscopic endonasal surgery (EES) for the management of sellar, suprasellar, and anterior skull base lesions is gaining popularity. Our aim was to analyze and present the clinical outcomes of EES for the management of these lesions in a community hospital setting.

Methods: We retrospectively reviewed the charts of 56 patients with sellar, suprasellar, and anterior skull base lesions who underwent EES between 2010 and 2018.

Vacancy cluster in ZnO films grown by pulsed laser deposition.

Undoped and Ga-doped ZnO films were grown on c-sapphire using pulsed laser deposition (PLD) at the substrate temperature of 600 °C. Positron annihilation spectroscopy study (PAS) shows that the dominant V-related defect in the as-grown undoped ZnO grown with relative low oxygen pressure P(O) is a vacancy cluster (most likely a V-nV complex with n = 2, 3) rather than the isolated V which has a lower formation energy. Annealing these samples at 900 °C induces out-diffusion of Zn from the ZnO film into the sapphire creating the V at the film/sapphire interface, which favors the formation of vacancy cluster containing relatively more V.

Reversible Tuning of Ferromagnetism and Resistive Switching in ZnO/Cu Thin Films.

Systematic magnetic, electronic, and electrical studies on the CuZnO/GaZnO cell structure grown on (001) sapphire by the pulsed laser deposition technique show that the Cu multivalent (Cu) ions modulate magnetic and resistive states of the cells. The magnetic moment is found to be reduced by ∼30% during the high resistance state (HRS) to low resistance state (LRS) switching. X-ray photoelectron spectroscopy results reveals an increase of the Cu/Cu oxidation state ratio (which has been determined by the relative positions of the Fermi level and the Cu acceptor level) during the HRS to LRS transition.

p-type doping of MgZnO films and their applications in optoelectronic devices.

A lithium and nitrogen codoping method has been employed to prepare p-type MgZnO films, and p-MgZnO/i-ZnO/n-ZnO structured light-emitting devices (LEDs) and photodetectors have been fabricated. The LEDs can work continuously for about 97 h under the injection of a 20 mA continuous current, which is the best value ever reported for ZnO-based LEDs. The performance of the photodetectors degrades little after several running cycles.

Radiology and endoscopic findings of silent maxillary sinus atelectasis and enophthalmos.

Objectives: The objective of this study is to discuss the presentation and surgical management of patients presenting with silent maxillary sinus atelectasis with enophthalmos (SMSAE).

Study Design And Methods: We performed an analysis of prospectively collected data on patients with maxillary sinus opacification and associated enophthalmos from 1999 to 2003. Patients were evaluated based on physical examination, nasal endoscopy, and computed tomographic findings.

Rhinosinusitis Task Force symptoms versus the Sinonasal Outcomes Test in patients evaluated for chronic rhinosinusitis.

Background: The aim of this study was to compare Rhinosinusitis Task Force (RSTF) symptom scores with Sinonasal Outcome Test 20 (SNOT-20) in patients with chronic rhinosinusitis (CRS) and controls.

Methods: An analysis was performed of prospectively collected data in patients with CRS (n=201) and controls (n=100). The severity of individual RSTF major and minor symptom scores graded on a visual analog scale and total symptom scores were compared between the two groups.

Important clinical symptoms in patients undergoing functional endoscopic sinus surgery for chronic rhinosinusitis.

Objective: To evaluate the prevalence and severity of individual Rhinosinusitis Task Force (RSTF) symptoms in patients with chronic rhinosinusitis (CRS) undergoing functional endoscopic sinus surgery (FESS).

Methods: Retrospective analysis of prospectively collected data in 201 patients treated with FESS. The prevalence and severity of individual RSTF major and minor symptom scores graded on a visual analogue scale (VAS) were compared.

Advances in imaging of the paranasal sinuses.

Imaging technology has played a significant role in the diagnosis and management of sinonasal disorders. Plain sinus films are almost exclusively replaced by CT in the work-up for inflammatory sinus disease. MRI provides complementary information to CT in cases of sinonasal and skull-base neoplasms.
