Is Resident-Driven Inpatient Care More Expensive? Challenging a Long-Held Assumption.

Purpose: The financial impact of graduate medical education (GME) on teaching hospitals remains poorly understood, while calls for increased federal support continue alongside legislative threats to reduce funding. Despite studies suggesting that residents are more "economical" than alternative providers, GME is widely believed to be an expensive investment. Assumptions that residents increase the cost of patient care have persisted in the absence of convincing evidence to the contrary.

In-Hospital Complications following Arthrotomy versus Arthroscopy for Septic Knee Arthritis: A Cohort-Matched Comparison.

There is a paucity of literature comparing the relative merits of open arthrotomy versus arthroscopy for the surgical treatment of septic knee arthritis. The primary goal of this study is to compare the risk of perioperative complications between these two surgical techniques. To this end, 560 patients treated for septic arthritis of the native knee with arthroscopy were statistically matched 1:1 with 560 patients treated with open arthrotomy.

#Selfharm on #Instagram: Examining User Awareness and Use of Instagram's Self-harm Reporting Tool.

Self-harm-related posts on social media are a growing public health concern. To address the high rate of self-harm posts on their platform, Instagram introduced (in 2016) a tool for users to anonymously report posts that suggest engagement in, or support for, self-harm. Grounded in diffusion of innovation and the theory of planned behavior, the purpose of this study was to evaluate awareness of, and intention to use, the self-harm reporting tool among Instagram users.

Significant Variations in the Luminescence of Samarium(II) Doped Strontium and Barium Octaborate as a Function of Excitation Wavelength and Sample Temperature.

The emission features characteristic of divalent samarium formed in samarium-doped barium octaborate (BaBO) and strontium borate (SrBO) have been studied as a function of excitation wavelength and sample temperature. The emission spectra of divalent samarium in both materials exhibit a surprisingly strong temperature dependence. When divalent samarium is doped into BaBO, changes in excitation wavelength and sample temperature both result in significant variations in the emission features associated with the material.

A Patient-Centered Utility Index for Non-Small Cell Lung Cancer in the United States.

A preference-based quality-of-life index for non-small cell lung cancer was developed with a subset of Functional Assessment of Cancer Therapy (FACT)-General (G) and FACT-Lung (L) items, based on clinician input and the literature. A total of 236 non-small cell lung carcinoma patients contributed their preferences, randomly allocated among three survey groups to decrease burden. The FACT-L Utility Index (FACT-LUI) was constructed with two methods: 1) multiattribute utility theory (MAUT), where a visual analog scale (VAS)-based index was transformed to standard gamble (SG); and 2) an unweighted index, where items were summed, normalized to a 0 to 1.

Characterization of Barium Borate Frameworks Using Raman Spectroscopy.

Systematic micro-Raman scattering investigations have been carried out on Sm doped 2(BaO)-n(BO) matrices for n = 4, 5, 8, and 2(BaO)-(NaO)-9(BO) using the 364 nm excitation of an Ar laser. The Raman results have been compared with the known structures of barium tetraborate, barium pentaborate, barium octaborate, and barium sodium nonaborate. An excellent correlation has been found between the BO/BO composition ratios for each product and intensity ratios of the designated BO and BO Raman peaks.

Luminescence Study of the Samarium(II) Sites in Samarium: Barium Octaborate as Differentiated by Excitation Wavelength and Temperature.

Divalent samarium incorporated in a barium octaborate matrix prepared by firing homogeneous precipitates has been studied with emission spectroscopy. One of the samarium sites associated with this product exhibits an extremely strong temperature dependence upon using an excitation wavelength of 532 nm. This effect allows for specific differentiation between the two major Sm(II) sites associated with this compound.

Photoluminescence and visible diffuse-reflection spectroscopic evidence of samarium reduction in air-fired samples of mixed samarium: strontium tetraborate precipitates.

Photoluminescence and visible diffuse-reflection spectroscopies have provided evidence of the reduction of samarium to the divalent state in samarium-doped strontium borate and pure samarium borate samples. The samples were prepared by the air firing of homogeneous precipitates of divalent strontium and trivalent samarium ions from aqueous solutions with saturated sodium tetraborate. The use of this method in the preparation of divalent lanthanide ions has not been reported previously.

Mnemonic effects of asthma medication in children.

Asthmatic children receiving theophylline or steroid-theophylline combination therapy and normal nonasthmatics were given tests of visual retention and paired-associate learning. The performance of children receiving combination therapy was significantly worse than that of the nonasthmatics 6-8 hours after receiving steroid medication, but not 22-24 or 46-48 hours after medication. Children receiving theophylline alone did not differ from nonasthmatics on these tasks.
