PSR J0740\(+\)6620 has a gravitational mass of \(2.08\pm 0.07~M_\odot\), which is the highest reliably determined mass of any neutron star. As a result, a measurement of its radius will provide ...unique insight into the properties of neutron star core matter at high densities. Here we report a radius measurement based on fits of rotating hot spot patterns to Neutron Star Interior Composition Explorer (NICER) and X-ray Multi-Mirror (XMM-Newton) X-ray observations. We find that the equatorial circumferential radius of PSR J0740\(+\)6620 is \(13.7^{+2.6}_{-1.5}\) km (68%). We apply our measurement, combined with the previous NICER mass and radius measurement of PSR J0030\(+\)0451, the masses of two other \(\sim 2~M_\odot\) pulsars, and the tidal deformability constraints from two gravitational wave events, to three different frameworks for equation of state modeling, and find consistent results at \(\sim 1.5-3\) times nuclear saturation density. For a given framework, when all measurements are included the radius of a \(1.4~M_\odot\) neutron star is known to \(\pm 4\)% (68% credibility) and the radius of a \(2.08~M_\odot\) neutron star is known to \(\pm 5\)%. The full radius range that spans the \(\pm 1\sigma\) credible intervals of all the radius estimates in the three frameworks is \(12.45\pm 0.65\) km for a \(1.4~M_\odot\) neutron star and \(12.35\pm 0.75\) km for a \(2.08~M_\odot\) neutron star.
Experiments conducted in rabbits showed no toxic effects on the retina by electroretinogram after vitrectomy when the infusion fluid contained as much as 50 microgram/ml of methicillin or lincomycin ...or 20 microgram/ml oxacillin. An abnormal electroretinogram was found in eyes receiving oxacillin in a concentration of 50 microgram/ml. Histologic studies showed ocular damage with concentrations of 50 microgram/ml of methicillin or lincomycin or 20 microgram/ml of oxacillin. All antibiotics were nontoxic to retina at 10 microgram/ml concentration, both by ERG and histology.
BACKGROUND: Treatment for cancer is trending toward oral therapies, which patients can self-manage from home. Proper adherence to oral therapy is vital to safe and optimal care in this setting. ...Mobile health interventions (i.e., text message reminders, mobile applications, and automated calls) are an evolving strategy aimed at improving medication adherence for patients on long-term oral therapies. OBJECTIVES: This review aims to provide an overview of research outcomes for the use of mobile health interventions among patients with cancer. METHODS: A comprehensive review of CINAHLR, MEDLINER, and PubMedRwas completed. Eleven articles were eligible for inclusion in this review. FINDINGS: Mobile health interventions are an acceptable approach among patients with cancer and may improve adherence outcomes for those at highest risk for suboptimal adherence.
The COVID-19 pandemic caused many hospitals and treatment centers to temporarily restrict or prohibit visitors to control viral spread. This article presents a case study of a patient receiving a ...bone marrow transplantation who experienced psychological distress during hospitalization because of social isolation. The National Comprehensive Cancer Network guidelines for distress management are used as a framework to outline a nursing plan of care for managing social isolation-related psychological distress in patients who are hospitalized during a worldwide pandemic.
The COVID-19 pandemic placed challenges on interprofessional communication patterns among clinical care teams at a time when effective communication was greatly needed. The development of enhanced ...systems for communication that integrate the latest evidence and communication technologies can offer a solution to this crisis.
This article provides a framework for ways in which nursing teams can develop evidence-based enhanced interprofessional communication systems during a pandemic.
Based on communication models and related technologies, this article reviews strategies to enhance interprofessional communication. Two case studies are included that illustrate how nursing teams can enhance communication during a pandemic.
To improve communication during a pandemic, clinicians can incorporate interprofessional communication models in clinical practice and apply enhanced communication strategies.
