Background: Emergency medicine (EM) physicians frequently care for seriously ill patients at the end of life. Palliative care initiated in the emergency department (ED) can improve symptom management and quality of life, align treatments with patient preferences, and reduce length of hospitalization. We evaluated an educational intervention with digital tools for palliative care discussions in an urban EM residency using the reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) framework.

We present a survey of variable stars detected in Campaign 13 within the massive intermediate-age (~1 Gyr) open cluster NGC 1817. We identify a complete sample of 44 red clump stars in the cluster, and have measured asteroseismic quantities ( and/or Δ) for 29 of them. Five stars showed suppressed dipole modes, and the occurrence rates indicate that mode suppression is unaffected by evolution through core helium burning.

The emphasis on professor-directed teaching and learning activities is shifting toward a more learner-centered approach. To incorporate appropriate active learning exercises into the PA classroom, instructors must plan, design, and execute pedagogically sound practices.

The association of a posterior cleft with variations in glenoid morphology or with shoulder instability is unknown.
Questions/purposes: The purposes of this study were to determine if posterior chondrolabral clefts are associated with variations in glenoid morphology, and to determine if they are associated with shoulder instability.
Objective: The purpose of this study is to compare CT urography (CTU) with unenhanced CT in the evaluation of upper urinary tracts in adults younger than 50 years with asymptomatic microscopic hematuria.
Materials And Methods: In this study, 1516 CTU examinations were reviewed in adults younger than 50 years. Inclusion criteria were no significant prior urologic disease and asymptomatic microscopic hematuria with at least one urinalysis with greater than or equal to 3 RBCs/high-power field and less than or equal to 50 RBCs/high-power field.
Several materials were tested as possible individual emergency dosimeters using Optically Stimulated Luminescence (OSL) as means to assess the exposure. Materials investigated included human nails, business cards and plastic buttons. The OSL properties of these materials were studied in comparison with those of teeth.

Gypsum wallboard (drywall) represents an attractive target for retrospective dosimetry by optically stimulated luminescence (OSL) in the event of a radiological accident or malicious use of nuclear material. In this study, wallboard is shown to display a radiation-induced luminescence signal (RIS) as well as a natural background signal (NS), which is comparable in intensity to the RIS. Excitation and emission spectra show that maximum luminescence intensity is obtained for stimulation with blue light-emitting diodes (470 nm) and for detection in the ultraviolet region (290-370 nm).
View Article and Find Full Text PDFOptically stimulated luminescence (OSL) properties of dental enamel are discussed with a view to the development of an in vivo dose assessment technique for medical triage following a radiological/nuclear accident or terrorist event. In the OSL technique, past radiation exposure is assessed by stimulating the sample with light of one wavelength and monitoring the luminescence at another wavelength, under the assumption that the luminescence originates from the recombination of radiation-induced charges trapped at metastable defects in the enamel and that the intensity of the luminescence signal is in proportion to the absorbed radiation dose. Several primary findings emerged from this research: (a) sensitivities varied considerably between different teeth and also between fragments of the same tooth, (b) OSL signals were found to decay rapidly during the first 12 h after irradiation and more slowly afterward, (c) the fading rate of the luminescence signal varied between fragments, and (d) blue light stimulation yields greater sensitivity than infra-red stimulation, while the OSL signal obtained with a high-intensity pulsed green-light laser was found not to be correlated with the radiation dose.

Heart rate (HR) is another measure used to evaluate exercise intensity. Additionally, affective responses to aerobic exercise have been studied and seem to be influenced by the intensity of the exercise.
View Article and Find Full Text PDFBackground And Purpose: Performing nontraditional abdominal exercises with devices such as abdominal straps, the Power Wheel, and the Ab Revolutionizer has been suggested as a way to activate abdominal and extraneous (nonabdominal) musculature as effectively as more traditional abdominal exercises, such as the crunch and bent-knee sit-up. The purpose of this study was to test the effectiveness of traditional and nontraditional abdominal exercises in activating abdominal and extraneous musculature.
Subjects: Twenty-one men and women who were healthy and between 23 and 43 years of age were recruited for this study.
The aim of this study is to report a novel description of a displaced tear of the lateral meniscus as a curvilinear low signal intensity band parallel and posteroinferior to the anterior cruciate ligament (ACL) on midline oblique sagittal magnetic resonance (MR) images, resulting in the appearance of a "double ACL." The appearance of a double ACL may potentially be a specific indicator for a lateral meniscal displaced tear. Increased awareness of this characteristic MR finding may increase accuracy in the diagnosis of displaced tears of the lateral meniscus.

The authors report the case of a rare mesenteric anomaly in a 71-year-old man who presented with a preexisting abdominal aortic aneurysm (AAA) and a progressive history of postprandial abdominal pain and 10-lb weight loss. Aortography revealed a common celiomesenteric trunk, an absent middle colic artery, and a stenotic inferior mesenteric artery. At operation, neural fibers compressing the common celiomesenteric trunk were lysed, the AAA was repaired, and the inferior mesenteric artery was subjected to endarterectomy and then reimplanted.

This study evaluates whether perceived preoperative markers of nutritional status recorded in charts correlates with postoperative complications and resource use in patients who receive no preoperative nutrition support and reinterprets the results of several conflicting randomized, prospective studies in this context.
Methods: This is a retrospective cohort study of 526 surgical patients who had preoperative serum albumin levels measured and were undergoing elective esophageal, gastric, pancreaticoduodenal, or colon surgery between 1992 and 1996 who could have received preoperative nutrition but did not.
Total parenteral nutrition (TPN) decreases intestinal IgA and levels of Th2 cytokines, interleukin (IL)-4, and IL-10 within the supernatants of intestinal homogenates. These cytokines are known to stimulate IgA production in vitro by cells of the gut-associated lymphoid tissue (GALT). Glutamine (GLN) supplementation of TPN normalizes GALT mass and cytokine levels.

This finding has been challenged by a report of NT immunity without IgA in knockout mice, suggesting that IgA may not be necessary for the protection of mucosal surfaces. Although other protective mechanisms may become active in the congenital absence of SIgA, these mechanisms are not the primary means of protection in normal mice.
