    This research aims to review the concepts of scenes and sequences from the teachings of masters in screenwriting. This objective stems from a descriptive methodological perspective: we propose to study some elements of the communication process of cinema and television narrative through scenes and sequences, defining both concepts and applying these notions to a particular audiovisual text through case analysis. Analysis will confirm that experts refer to the term scene for different realities, generating confusion among audiovisual narrative scholars. We propose a distinction of the term scene into two different concepts: the scene and the narrative scene, which, in fact, are two different parts. As far as the sequence notion is concerned, there is enough consensus regarding its constitutive nature, although there are interesting nuances among authors, some of whom emphasize the relevance of the central conflict, whilst others emphasize the completeness of the event in the sequence. Employing the case method, the theoretical notions studied here are applied to a Pilot episode of Breaking Bad, in order to contribute to the elucidation of the concepts, the object of this investigation, and verify the coherence of the proposal.La presente investigación tiene por objeto hacer una revisión de los conceptos de escena y secuencia a partir de las enseñanzas de algunos de los principales maestros de la escritura del guion. Este objetivo se enmarca dentro de una perspectiva metodológica descriptiva: pretendemos estudiar algunos elementos del proceso de comunicación constitutivos de la narrativa del cine y la televisión, como son las escenas y las secuencias, llegando a una definición de ambos conceptos, para más adelante aplicar dichos conceptos a un texto audiovisual concreto a través del análisis de un caso. Tras el examen teórico, se ha constatado que los expertos se refieren con el término escena a realidades distintas, generando confusión con ello entre los estudiosos de la narrativa audiovisual, por lo que se propone una división del término escena en dos: escena y escena narrativa, para referirse a dos unidades narrativas que de hecho son distintas. En lo que concierne a la secuencia se ha comprobado que hay bastante unanimidad respecto a su naturaleza constitutiva, aunque también existen interesantes matices entre los autores, poniendo unos el énfasis en la relevancia del conflicto central, frente a otros que subrayan el carácter de completo del acontecimiento primordial de la secuencia. Utilizando el método del caso, se aplican los conceptos teóricos estudiados al episodio Pilot de Breaking Bad, con el fin de contribuir al esclarecimiento de los conceptos objeto de esta investigación y constatar la coherencia de la propuesta

    BACKGROUND: Follow-up of abnormal outpatient laboratory test results is a major patient safety concern. Electronic medical records can potentially address this concern through automated notification. We examined whether automated notifications of abnormal laboratory results (alerts) in an integrated electronic medical record resulted in timely follow-up actions. METHODS: We studied 4 alerts: hemoglobin A1c \u3e or =15%, positive hepatitis C antibody, prostate-specific antigen \u3e or =15 ng/mL, and thyroid-stimulating hormone \u3e or =15 mIU/L. An alert tracking system determined whether the alert was acknowledged (ie, provider clicked on and opened the message) within 2 weeks of transmission; acknowledged alerts were considered read. Within 30 days of result transmission, record review and provider contact determined follow-up actions (eg, patient contact, treatment). Multivariable logistic regression models analyzed predictors for lack of timely follow-up. RESULTS: Between May and December 2008, 78,158 tests (hemoglobin A1c, hepatitis C antibody, thyroid-stimulating hormone, and prostate-specific antigen) were performed, of which 1163 (1.48%) were transmitted as alerts; 10.2% of these (119/1163) were unacknowledged. Timely follow-up was lacking in 79 (6.8%), and was statistically not different for acknowledged and unacknowledged alerts (6.4% vs 10.1%; P =.13). Of 1163 alerts, 202 (17.4%) arose from unnecessarily ordered (redundant) tests. Alerts for a new versus known diagnosis were more likely to lack timely follow-up (odds ratio 7.35; 95% confidence interval, 4.16-12.97), whereas alerts related to redundant tests were less likely to lack timely follow-up (odds ratio 0.24; 95% confidence interval, 0.07-0.84). CONCLUSIONS: Safety concerns related to timely patient follow-up remain despite automated notification of non-life-threatening abnormal laboratory results in the outpatient setting

    Timely follow-up of abnormal diagnostic imaging test results in an outpatient setting: are electronic medical records achieving their potential?

    BACKGROUND: Given the fragmentation of outpatient care, timely follow-up of abnormal diagnostic imaging results remains a challenge. We hypothesized that an electronic medical record (EMR) that facilitates the transmission and availability of critical imaging results through either automated notification (alerting) or direct access to the primary report would eliminate this problem. METHODS: We studied critical imaging alert notifications in the outpatient setting of a tertiary care Department of Veterans Affairs facility from November 2007 to June 2008. Tracking software determined whether the alert was acknowledged (ie, health care practitioner/provider [HCP] opened the message for viewing) within 2 weeks of transmission; acknowledged alerts were considered read. We reviewed medical records and contacted HCPs to determine timely follow-up actions (eg, ordering a follow-up test or consultation) within 4 weeks of transmission. Multivariable logistic regression models accounting for clustering effect by HCPs analyzed predictors for 2 outcomes: lack of acknowledgment and lack of timely follow-up. RESULTS: Of 123 638 studies (including radiographs, computed tomographic scans, ultrasonograms, magnetic resonance images, and mammograms), 1196 images (0.97%) generated alerts; 217 (18.1%) of these were unacknowledged. Alerts had a higher risk of being unacknowledged when the ordering HCPs were trainees (odds ratio [OR], 5.58; 95% confidence interval [CI], 2.86-10.89) and when dual-alert (\u3e1 HCP alerted) as opposed to single-alert communication was used (OR, 2.02; 95% CI, 1.22-3.36). Timely follow-up was lacking in 92 (7.7% of all alerts) and was similar for acknowledged and unacknowledged alerts (7.3% vs 9.7%; P = .22). Risk for lack of timely follow-up was higher with dual-alert communication (OR, 1.99; 95% CI, 1.06-3.48) but lower when additional verbal communication was used by the radiologist (OR, 0.12; 95% CI, 0.04-0.38). Nearly all abnormal results lacking timely follow-up at 4 weeks were eventually found to have measurable clinical impact in terms of further diagnostic testing or treatment. CONCLUSIONS: Critical imaging results may not receive timely follow-up actions even when HCPs receive and read results in an advanced, integrated electronic medical record system. A multidisciplinary approach is needed to improve patient safety in this area

    <p>Abstract</p> <p>Background</p> <p>Health information technology and electronic medical records (EMRs) are potentially powerful systems-based interventions to facilitate diagnosis and treatment because they ensure the delivery of key new findings and other health related information to the practitioner. However, effective communication involves more than just information transfer; despite a state of the art EMR system, communication breakdowns can still occur. <abbrgrp><abbr bid="B1">1</abbr><abbr bid="B2">2</abbr><abbr bid="B3">3</abbr></abbrgrp> In this project, we will adapt a model developed by the Systems Engineering Initiative for Patient Safety (SEIPS) to understand and improve the relationship between work systems and processes of care involved with electronic communication in EMRs. We plan to study three communication activities in the Veterans Health Administration's (VA) EMR: electronic communication of abnormal imaging and laboratory test results via automated notifications (<it>i.e.</it>, alerts); electronic referral requests; and provider-to-pharmacy communication via computerized provider order entry (CPOE).</p> <p>Aim</p> <p>Our specific aim is to propose a protocol to evaluate the systems and processes affecting outcomes of electronic communication in the computerized patient record system (related to diagnostic test results, electronic referral requests, and CPOE prescriptions) using a human factors engineering approach, and hence guide the development of interventions for work system redesign.</p> <p>Design</p> <p>This research will consist of multiple qualitative methods of task analysis to identify potential sources of error related to diagnostic test result alerts, electronic referral requests, and CPOE; this will be followed by a series of focus groups to identify barriers, facilitators, and suggestions for improving the electronic communication system. Transcripts from all task analyses and focus groups will be analyzed using methods adapted from grounded theory and content analysis.</p

    Dynamic constriction and fission of endoplasmic reticulum membranes by reticulon

    Get PDF
    The endoplasmic reticulum (ER) is a continuous cell-wide membrane network. Network formation has been associated with proteins producing membrane curvature and fusion, such as reticulons and atlastin. Regulated network fragmentation, occurring in different physiological contexts, is less understood. Here we find that the ER has an embedded fragmentation mechanism based upon the ability of reticulon to produce fission of elongating network branches. In Drosophila, Rtnl1-facilitated fission is counterbalanced by atlastin-driven fusion, with the prevalence of Rtnl1 leading to ER fragmentation. Ectopic expression of Drosophila reticulon in COS-7 cells reveals individual fission events in dynamic ER tubules. Consistently, in vitro analyses show that reticulon produces velocity-dependent constriction of lipid nanotubes leading to stochastic fission via a hemifission mechanism. Fission occurs at elongation rates and pulling force ranges intrinsic to the ER, thus suggesting a principle whereby the dynamic balance between fusion and fission controlling organelle morphology depends on membrane motility
