Increasing Effectiveness of the Surgical Airway Response System: Introduction of the Otolaryngology Airway Pager, Quality Improvement Project of the PGY-2 Class

Introduction: The need for an Otolaryngology airway pager is based on several external and internal factors. The current communication pathway for emergent airways at our institution is well established but often misinterpreted. The protocol is outlined in Figure 1. The priority to reach out to other departments is based on their availability of an attending in house overnight. Furthermore, there is often a delay in contacting the Otolaryngology department. Our service has multiple pagers to accommodate for each of our inpatient teams, which can be confusing for other services. One of the driving events for this project was an incident at JHN where a tracheostomy tube became dislodged. There were several attempts to contact our team through the wrong pager and by the time we were notified the patient had expired. In addition our personal cell phones are commonly used as the primary means of contact for urgent situations. On several occasions the wrong person has been called in the middle of the night or the on-call resident is contacted while they are in the operating room during the day, resulting in a slower response time. From the perspective of the Otolaryngology Department at times we receive multiple pages and answer in the order that the pages were received, not in order of acuity as this is unknown. A dedicated airway pager will help us prioritize our decisions most safely.https://jdc.jefferson.edu/patientsafetyposters/1067/thumbnail.jp

The Use of Maintenance Electroconvulsive Therapy for Relapsing Depression

It is generally accepted that electroconvulsive therapy (ECT) is an effective treatment of major depressive episodes in patients with both unipolar and bipolar affective disorders (1). Yet, repeated relapse of depression occurs in some patients, even with vigorous maintenance therapy on antidepressant drugs (2-4). This often necessitates rehospitalization for ECT. In past decades, several authors suggested that periodic outpatient ECT was efficacious as a maintenance therapy (5-7). Recently, maintenance ECT was recommended by Fink (8), and Maletzky (9), but barely mentioned in two reviews (10,11), and discouraged in another (12) . However, a recent nationwide survey has disclosed that such therapy is widely practiced (13)

Consideration of a New Definition of Clinically Relevant Myocardial Infarction After Coronary Revascularization An Expert Consensus Document From the Society for Cardiovascular Angiography and Interventions (SCAI)

Numerous definitions have been proposed for the diagnosis of myocardial infarction (MI) after coronary revascularization. The universal definition for MI designates post procedural biomarker thresholds for defining percutaneous coronary intervention (PCI)-related MI (type 4a) and coronary artery bypass grafting (CABG)-related MI (type 5), which are of uncertain prognostic importance. In addition, for both the MI types, cTn is recommended as the biomarker of choice, the prognostic significance of which is less well validated than CK-MB. Widespread adoption of a MI definition not clearly linked to subsequent adverse events such as mortality or heart failure may have serious consequences for the appropriate assessment of devices and therapies, may affect clinical care pathways, and may result in misinterpretation of physician competence. Rather than using an MI definition sensitive for small degrees of myonecrosis (the occurrence of which, based on contemporary large-scale studies, are unlikely to have important clinical consequences), it is instead recommended that a threshold level of biomarker elevation which has been strongly linked to subsequent adverse events in clinical studies be used to define a "clinically relevant MI." The present document introduces a new definition for "clinically relevant MI" after coronary revascularization (PCI or CABG), which is applicable for use in clinical trials, patient care, and quality outcomes assessment. Numerous definitions for the diagnosis of MI after coronary revascularization are in use (1). A standardized MI definition would provide uniformity for comparing clinical trial results, for assessing patient outcomes and for guiding quality improvement initiatives. In 2007, a "universal definition" for MI following coronary revascularization was proposed (2) and recently revised in 2012 (3). In this document, a PCI-related MI (type 4a) was defined as an increase in cTn to >5Â the 99th percentile of the URL during the first 48 h following PCI (in patients with normal baseline cTn concentrations), plus either: 1) evidence of prolonged ischemia as demonstrated by prolonged chest pain; or 2) ischemic ST-segment changes or new pathological Q waves; or 3) angiographic evidence of a flow limiting complication; or 4) imaging evidence of new loss of viable myocardium or new regional wall motion abnormality. MI associated with CABG (type 5) was defined as an increase in cTn to >10Â the 99th percentile URL during the first 48 h following CABG (in patients with normal baseline cTn concentrations), plus either: 1) new pathological Q waves or new LBBB; or 2) angiographically documente

Positive words carry less information than negative words

We show that the frequency of word use is not only determined by the word length \cite{Zipf1935} and the average information content \cite{Piantadosi2011}, but also by its emotional content. We have analyzed three established lexica of affective word usage in English, German, and Spanish, to verify that these lexica have a neutral, unbiased, emotional content. Taking into account the frequency of word usage, we find that words with a positive emotional content are more frequently used. This lends support to Pollyanna hypothesis \cite{Boucher1969} that there should be a positive bias in human expression. We also find that negative words contain more information than positive words, as the informativeness of a word increases uniformly with its valence decrease. Our findings support earlier conjectures about (i) the relation between word frequency and information content, and (ii) the impact of positive emotions on communication and social links.Comment: 16 pages, 3 figures, 3 table

The Effect of 3D Printed Models on Surgical Planning and Outcomes for Partial Nephrectomies

Purpose: Partial nephrectomies to remove renal masses are kidney-sparing procedures that rely on anatomical comprehension. Prior research demonstrates complex and expensive 3D models (~$1000) increased surgeons’ confidence in selecting their operative plan. We aim to use simpler and cheaper 3D models to improve preoperative surgeon confidence and support operative management. Methods: 3D printed models (~$35) of the affected kidney, mass, and renal vasculature were created using preoperative CT or MRI imaging of 17 patients presenting for partial nephrectomies at Thomas Jefferson University (TJU) between July and December 2020. The models were created at TJU using Ultimaker technology. Surgeons filled out three surveys assessing their surgical plan and confidence in the plan: before seeing the model, after seeing the model before surgery, and after surgery. Patients with 3D modeling were crossmatched by demographics and operative technique with patients without 3D modeling who had partial nephrectomies between 2018 - 2019. Results and Conclusions: 16 of 17 attendings completed the surveys. Surgeon confidence increased before (7.6) and after seeing the 3D model (7.9) on a 10-point scale (10=most confident). On postoperative surveys, attendings rated the models 8.3 out of 10 in their helpfulness to anatomical comprehension. Patients with 3D modeling had slightly higher rates of selective renal artery clamping over complete vascular clamping when compared to crossmatched partial nephrectomies without 3D modeling. Cost-effective 3D models can be helpful tools for surgeons to understand anatomical relationships and reduce complete vascular clamping that may be difficult with imaging alone. Other surgical fields may benefit from preoperative education through 3D modeling

Chronic Beryllium Disease and Sensitization at a Beryllium Processing Facility

We conducted a medical screening for beryllium disease of 577 former workers from a beryllium processing facility. The screening included a medical and work history questionnaire, a chest radiograph, and blood lymphocyte proliferation testing for beryllium. A task exposure and a job exposure matrix were constructed to examine the association between exposure to beryllium and the development of beryllium disease. More than 90% of the cohort completed the questionnaire, and 74% completed the blood and radiograph component of the screening. Forty-four (7.6%) individuals had definite or probable chronic beryllium disease (CBD), and another 40 (7.0%) were sensitized to beryllium. The prevalence of CBD and sensitization in our cohort was greater than the prevalence reported in studies of other beryllium-exposed cohorts. Various exposure measures evaluated included duration; first decade worked; last decade worked; cumulative, mean, and highest job; and highest task exposure to beryllium (to both soluble and nonsoluble forms). Soluble cumulative and mean exposure levels were lower in individuals with CBD. Sensitized individuals had shorter duration of exposure, began work later, last worked longer ago, and had lower cumulative and peak exposures and lower nonsoluble cumulative and mean exposures. A possible explanation for the exposure–response findings of our study may be an interaction between genetic predisposition and a decreased permanence of soluble beryllium in the body. Both CBD and sensitization occurred in former workers whose mean daily working lifetime average exposures were lower than the current allowable Occupational Safety and Health Administration workplace air level of 2 μg/m(3) and the Department of Energy guideline of 0.2 μg/m(3)

Application of the Phenomenex EZ:faast™ amino acid analysis kit for rapid gas-chromatographic determination of concentrations of plasma tryptophan and its brain uptake competitors

The Phenomenex EZ:faast™ amino acid analysis kit is available for gas (GC) or liquid (LC) chromatographic analysis of amino acids (AA) using mass spectrometry (MS) and other GC detectors. We used it for rapid GC determination of plasma tryptophan, its brain uptake competitors (Val, Leu, Ile, Phe and Tyr) and many other amino acids. Based on solid-phase extraction, this fast method enables one person to process two plasma samples in 8–10 min and six samples in ∼15 min up to GC injection and a 7-min GC run per plasma sample. Using a Perkin-Elmer Clarus 500 GC, a Total Chrome software, a flame-ionisation detector (FID) and norvaline as internal standard, we used this method to analyse ∼1,000 plasma samples from normal subjects undergoing acute tryptophan depletion and loading tests. The limit of detection for most amino acids is 1 nmol/ml (1 μM) and in many cases less. With manual injection, coefficients of variation for the above six amino acids were 1.5–6.2% (intra-assay) and 3.8–9.7% (inter-assay). This simple, rapid and elegant method will be valuable to the amino acid analyst and researcher, as it can save much manpower time and meet urgent emergency requests and the demands of a high-throughput laboratory

Forefoot plantar multilobular noninfiltrating angiolipoma: a case report and review of the literature

<p>Abstract</p> <p>Background</p> <p>Soft tissue tumors of the feet are uncommon and there have been very few reports of large series in the literature. These tumors continue to present the clinician with one of the most difficult problems in medicine.</p> <p>Case presentation</p> <p>We present a case of a large multilobular noninfiltrating angiolipoma at the plantar surface of the forefoot. Only three cases occurring at the foot have been previously described. We report this new case due to unusual location of the tumor, the long duration (25 years) of its existence and the unique surgical approach for the tumor excision.</p> <p>Conclusion</p> <p>Surgical excision is the treatment of choice and adjuvant radiotherapy is indicated in select cases.</p
