Ultra-dense Green InGaN/GaN Nanoscale Pixels with High Luminescence Stability and Uniformity for Near-Eye Displays.

Ultra-dense (>4,000 pixels per inch) and highly stable full-color III-nitride nanoscale pixels are crucial for near-eye display technologies like virtual and augmented-reality glasses. In this context, InGaN-based long wavelength green microscale light-emitting diodes face major bottlenecks, such as low efficiency and inadequate wavelength stability. These challenges are associated with the presence of both nonradiative surface defects and the strain induced quantum-confined Stark effect.

The SelfSTarT intervention for low back pain patients presenting to first contact physiotherapists: A mixed methods service evaluation.

Introduction: Globally, back pain is the leading cause of years of disability. In the United Kingdom, over 20 million people live with musculoskeletal (MSK) pain, with low back pain being one of the most common causes. National strategies promote self-management and the use of digital technologies to empower populations.

Effects of a Preventive Mental Health Curriculum Embedded Into a Scholarly Gaming Course on Adolescent Self-Esteem: Prospective Matched Pairs Experiment.

Background: Positive self-esteem predicts happiness and well-being and serves as a protective factor for favorable mental health. Scholarly gaming within the school setting may serve as a channel to deliver a mental health curriculum designed to improve self-esteem.

Objective: This study aims to evaluate the impact of a scholarly gaming curriculum with and without an embedded preventive mental health curriculum, Mental Health Moments (MHM), on adolescents' self-esteem.

Prevalence of Childhood Hearing Loss in Rural Alaska.

Objectives: Childhood hearing loss has well-known lifelong consequences. Certain rural populations are at higher risk for infection-related hearing loss. For Alaska Native children, historical data on hearing loss prevalence suggest a higher burden of infection-related hearing loss, but updated prevalence data are urgently needed in this high-risk population.

Telemedicine Referral to Improve Access to Specialty Care for Preschool Children in Rural Alaska: A Cluster-Randomized Controlled Trial.

Objectives: Preschool programs provide essential preventive services, such as hearing screening, but in rural regions, limited access to specialists and loss to follow-up compound rural health disparities. We conducted a parallel-arm cluster-randomized controlled trial to evaluate telemedicine specialty referral for preschool hearing screening. The goal of this trial was to improve timely identification and treatment of early childhood infection-related hearing loss, a preventable condition with lifelong implications.

Changing the Paradigm for School Hearing Screening Globally: Evaluation of Screening Protocols From Two Randomized Trials in Rural Alaska.

Objectives: Diagnostic accuracy was evaluated for various screening tools, including mobile health (mHealth) pure-tone screening, tympanometry, distortion product otoacoustic emissions (DPOAE), and inclusion of high frequencies to determine the most accurate screening protocol for identifying children with hearing loss in rural Alaska where the prevalence of middle ear disease is high.

Design: Hearing screening data were collected as part of two cluster randomized trials conducted in 15 communities in rural northwest Alaska. All children enrolled in school from preschool to 12th grade were eligible.

Management of Psychosis Associated with Graves' Disease: A Rare Case Report.

Graves' disease is an autoimmune disease in which patients can rarely present with psychiatric symptoms. In these patients, detailed history with psychiatric evaluation using a mental status examination is crucial for the early identification of psychiatric manifestations. Early intervention with medical and surgical therapy can help effectively treat the condition and prevent adverse outcomes such as catatonia.

Retrospective validation of acute heart failure risk stratification in the emergency department.

Background: Heart Failure (HF) is a primary diagnosis for hospital admission from the Emergency Department (ED), although not all patients require hospitalization. The Emergency Heart Failure Mortality Risk Grade (EHMRG) estimates 7-day mortality in patients with acute HF in ED settings, but further validation is needed in the United States (US).

Objectives: To validate EHMRG scores by risk-stratifying patients with acute HF in a large tertiary healthcare center in the US and analyze outcome measures to determine if EHMRG risk scores safely identify low-risk groups that may be discharged or managed in ED observation units (EDOUs).

Mobile health school screening and telemedicine referral to improve access to specialty care in rural Alaska: a cluster- randomised controlled trial.

Background: School-based programmes, including hearing screening, provide essential preventive services for rural children. However, minimal evidence on screening methodologies, loss to follow-up, and scarcity of specialists for subsequent care compound rural health disparities. We hypothesised telemedicine specialty referral would improve time to follow-up for school hearing screening compared with standard primary care referral.

Acute Toxicity of Major Geochemical Ions to Fathead Minnows (Pimephales promelas): Part B-Modeling Ion Toxicity.

Mathematical models are presented for the acute median lethal concentrations of major geochemical ions (Na , K , Ca , Mg , Cl , SO , HCO /CO ) to fathead minnows (Pimephales promelas), based on an extensive series of experiments presented in a companion article. Toxicity relationships across different dilution waters, individual salts, and salt mixtures suggest six independent mechanisms of toxicity to consider in modeling efforts, including Mg/Ca-specific toxicity, osmolarity-related toxicity, SO -specific toxicity, K-specific toxicity, effects of high pH/alkalinity, and a multiple ion-related toxicity at low Ca distinct from the other mechanisms. Models are evaluated using chemical activity-based exposure metrics pertinent to each mechanism, but concentration-based alternative models that are simpler to apply are also addressed.

Acute Toxicity of Major Geochemical Ions to Fathead Minnows (Pimephales Promelas): Part A-Observed Relationships for Individual Salts and Salt Mixtures.

The results of a series of experiments on the acute toxicity of major geochemical ions (Na , K , Ca , Mg , Cl , SO , HCO /CO ) to fathead minnows (Pimephales promelas) are reported. Tests of individual major ion salts in various dilution waters demonstrated that the toxicities of Na, Mg, and K salts decrease as the overall ion content of the dilution water increases. For Na and Mg salts, this is attributable to Ca content as previously reported for Ceriodaphnia dubia.

Same-Day Discharge Protocol for Robot-Assisted Radical Prostatectomy: Experience of a High-Volume Referral Center.

As the coronavirus disease 2019 (COVID-19) global pandemic continues, there is increased value in performing same-day discharge (SDD) protocols to minimize viral exposure and maintain the appropriate surgical treatment for oncologic patients. In this scenario, we performed a prospective analysis of outcomes of our patients undergoing SDD protocol after robot-assisted radical prostatectomy (RARP). The SDD criteria included patients with no intraoperative complications, stable postoperative hemoglobin levels (compared with preoperative values), stable vital signs, normal urine output, ambulation with assistance and independently without dizziness, tolerance of clear liquids without nausea or vomiting, pain control with oral medication, and patient/family confidence with SDD.

Robtic-assisted radical cystectomy: Literature review.

Radical cystectomy (RC) with pelvic lymph node dissection (PLND) is the standard treatment for localized muscle-invasive bladder cancer (MIBC) and non-muscle-invasive bladder cancer (NMIBC) with recurrence or high risk of progression. Also, the robotic approach to this type of surgery is well established in the literature. Our objective is to summarize in this manuscript the most relevant articles related to the robotic-assisted radical cystectomy for prostate cancer.

Hearing Norton Sound: community involvement in the design of a mixed methods community randomized trial in 15 Alaska Native communities.

Community involvement is important in good research practice. We led a community-based study to improve early detection and treatment of childhood hearing loss in rural Alaska. This study evaluated a cell phone-based hearing screening process and compared a new telemedicine specialty referral pathway to the standard primary care referral pathway.

Use of transversus abdominis plane block to decrease pain scores and narcotic use following robot-assisted laparoscopic prostatectomy.

The aim of this study was to assess whether transversus abdominis plane (TAP) blocks can be utilized to decrease patient pain scores and narcotic use during the first 24 h following robot-assisted laparoscopic prostatectomy (RALP). 100 patients received a TAP block with a mixture of 1.3% liposomal bupivacaine, 0.

Changing clinical trends in 10 000 robot-assisted laparoscopic prostatectomy patients and impact of the 2012 US Preventive Services Task Force's statement against PSA screening.

Objectives: To evaluate the clinical trend changes in our robot-assisted laparoscopic prostatectomy (RALP) practice and to investigate the effect of 2012 US Preventive Services Task Force (USPSTF) statement against PSA screening on these trends.

Patients And Methods: Data of 10 000 RALPs performed by a single surgeon between 2002 and 2017 were retrospectively analysed. Time trends in successive 1000 cases for clinical, surgical and pathological characteristics were analysed with linear and logistic regression.

Acute Cardiometabolic Responses to Multi-Modal Integrative Neuromuscular Training in Children.

Integrative neuromuscular training (INT) has emerged as an effective strategy for improving health- and skill-related components of physical fitness, yet few studies have explored the cardiometabolic demands of this type of training in children. The aim of this study was to examine the acute cardiometabolic responses to a multi-modal INT protocol and to compare these responses to a bout of moderate-intensity treadmill (TM) walking in children. Participants ( = 14, age 10.

The relative importance of waterborne and dietborne As exposure on survival and growth of juvenile fathead minnows.

The survival and growth of juvenile fathead minnows were investigated at various combinations of waterborne exposure to arsenate and of dietborne exposure to oligochaete worms which had been exposed to inorganic arsenic. Previous work with rainbow trout established that dietborne arsenic can reduce fish growth at environmentally relevant concentrations and could be more important than waterborne exposures. This was found to be less true for fathead minnows, which were less sensitive to dietborne exposures than rainbow trout, while being as or more sensitive to waterborne exposures.

The effects of arsenic speciation on accumulation and toxicity of dietborne arsenic exposures to rainbow trout.

The effects on juvenile rainbow trout survival, growth, food consumption, and food conversion efficiency from dietborne exposures to inorganic arsenic (arsenite, arsenate) and to the organoarsenicals monomethylarsonate (MMA), dimethylarsinate (DMA), and arsenobetaine (AsB) were investigated in two experiments: (1) a 28-d exposure using live diets of oligochaete worms separately exposed via water to these five arsenic compounds and (2) a 56-d exposure using pellet diets prepared from commercial fish food to which arsenite, MMA, or DMA were added. In the live diet experiment, the degree to which worms could be contaminated with the organoarsenicals was limited by toxicity to the worms and other experimental constraints, so that their toxicity relative to inorganic arsenic could not be fully established, but AsB was concluded to have low toxicity, consistent with published results for mammals. For the pellet diet experiment, MMA and DMA were found to be at least an order of magnitude less toxic than inorganic As on the basis of concentration in the diet, as well as much less toxic on the basis of accumulation in the fish.

Violence risk-assessment screening tools for acute care mental health settings: Literature review.

Background: Violence is a large concern for mental health professionals: 90% of physicians and nurses working in mental health areas have been subject to violence from patients. Approximately 80% of violent acts from patients are directed toward nurses.

Objective: The purpose of this integrative literature review was to identify violence risk-assessment screening tools that could be used in acute care mental health settings.

Chronic toxicity of major ion salts and their mixtures to Ceriodaphnia dubia.

In previous work we intensively studied the acute responses of the cladoceran Ceriodaphnia dubia to major geochemical ions (Na , K , Ca , Mg , Cl , SO , and HCO /CO ), culminating in the development of models to predict acute toxicity from ionic composition. To quantitatively evaluate whether the toxicological behavior of major ions observed for C. dubia extends to chronic toxicity, we conducted 58 chronic toxicity tests with individual major salts and binary mixtures thereof.

Salvage robotic-assisted radical prostatectomy: oncologic and functional outcomes from two high-volume institutions.

Introduction: While no consensus on the optimal salvage treatment exists, only 3% of these patients will get salvage radical prostatectomies due to the assumed technical challenges of this procedure.

Objectives: Our goal is to analyze the perioperative, oncologic and functional outcomes of patients undergoing salvage robotic-assisted radical prostatectomy (sRARP) after primary treatment failure.

Materials And Methods: Data were prospectively collected and retrospectively reviewed from a combined database of more than 14,800 patients who had undergone RARP.

The eardrums move when the eyes move: A multisensory effect on the mechanics of hearing.

Interactions between sensory pathways such as the visual and auditory systems are known to occur in the brain, but where they first occur is uncertain. Here, we show a multimodal interaction evident at the eardrum. Ear canal microphone measurements in humans ( = 19 ears in 16 subjects) and monkeys ( = 5 ears in three subjects) performing a saccadic eye movement task to visual targets indicated that the eardrum moves in conjunction with the eye movement.
