Bibliometric analysis of peer-reviewed literature on perinatal depression in Mexico / Análisis bibliométrico de la literatura revisada por pares sobre depresión perinatal en México

Abstract Background Perinatal depression (PND) is a clinical disease developed in any stage during the pregnancy and postpartum period with serious health and economic implications. Objective The aim of this work was to analyze via bibliometrics indicators Mexico's production on PND to provide a view of the academic landscape and a comprehensive reference for subsequent research in the country. Method The Scopus and Web of Science (WoS) databases were used to perform a search for peer reviewed papers related to PND in México. The search was made following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The extracted data were processed with VOS Viewer to examine link strength and clusters associations of diverse bibliometrics variables. Results A total of 132 records were retrieved and we included 70 studies in the bibliometric analysis after application of the exclusion criteria. The authors with more papers were Navarrete L., and Asunción Lara M. The institutions with more papers were the National Institute of Perinatology, Ramón de la Fuente National Institute of Psychiatry, and National Institute of Public Health of Mexico. A diminution of the research considered in PND is observed in the last two years. Four keyword clusters were identified related to PND: symptoms, prevalence, pregnancy. Discussion and conclusion The scarce literature concerning PND in Mexico compared with other countries could be due the limited collaboration between the health institutes. An urgent need to increase research on PND in Mexico is evident to be applicable in the management of resources in the healthcare system.

O prazer nas modalidades esportivas de combate: a pulsão de morte e a experiência do espectadora / The pleasure in combat sport modalities: the death drive and the spectator’s experience / El placer en las modalidades deportivas de combate: la pulsión de muerte y la experiencia del espectador

Este artigo analisa brevemente a história do combate esportivo, a fim de elucidar algumas características dos espetáculos das modalidades esportivas de combate na sociedade capitalista contemporânea, na medida em que a indústria cultural vende as competições esportivas como mercadoria. Com esse viés, a reflexão se detém em um estudo preliminar sobre o prazer do espectador no ato de assistir aos espetáculos. Nessa perspectiva, propomos a concepção das lutas "estéticas", considerando-as como aquelas que podem proporcionar maior prazer aos espectadores. Para essa tarefa, utilizamos a teoria psicanalítica, sublinhando sobretudo a metapsicologia freudiana a respeito do prazer e da pulsão de morte para descrever que, por meio de mecanismos de identificação e projeção, o espectador pode expressar indiretamente sua agressividade ao assistir aos espetáculos das modalidades esportivas de combate.

The present article makes a brief analysis of the history of combat sports in order to elucidate some of their main characteristics in the contemporary capitalist society, keeping in mind that the cultural industry deals with sport competitions as trading products. That said, the reflection focus on a preliminary study approaching the viewer’s pleasure when watching the combat shows. Within this context, we propose the concept of "esthetic" fights, considering them as those that can provide the highest level of pleasure to the watcher. For this objective, we make use of the psychoanalytic theory, highlighting the Freudian metapsychology taking into consideration the pleasure and the death drive, to describe that through identification and projection mechanisms the spectators can indirectly express their aggression, while watching combat sports events.

Efficient medical image access in diagnostic environments with limited resources

Abstract Introduction A medical application running outside the workstation environment has to deal with several constraints, such as reduced available memory and low network bandwidth. The aim of this paper is to present an approach to optimize the data flow for fast image transfer and visualization on mobile devices and remote stationary devices. Methods We use a combination of client- and server-side procedures to reduce the amount of information transferred by the application. Our approach was implemented on top of a commercial PACS and evaluated through user experiments with specialists in typical diagnosis tasks. The quality of the system outcome was measured in relation to the accumulated amount of network data transference and the amount of memory used in the host device. Besides, the system's quality of use (usability) was measured through participants’ feedback. Results Contrarily to previous approaches, ours keeps the application within the memory constraints, minimizing data transferring whenever possible, allowing the application to run on a variety of devices. Moreover, it does that without sacrificing the user experience. Experimental data point that over 90% of the users did not notice any delays or degraded image quality, and when they did, they did not impact on the clinical decisions. Conclusion The combined activities and orchestration of our methods allow the image viewer to run on resource-constrained environments, such as those with low network bandwidth or little available memory. These results demonstrate the ability to explore the use of mobile devices as a support tool in the medical workflow.

Setting Up a CR Based Filmless Environment for the Radiation Oncology / 의학물리

The analog image based system consisted of a simulator and medical linear accelerator (LINAC) for radiotherapy was upgraded to digital medical image based system by exchanging the X-ray film with Computed Radiography (CR). With minimum equipments shift and similar treatment process, it was possible that the new digital image system was adapted by the users in short time. The film cassette and the film developer device were substituted with a CR cassette and a CR Reader, where the ViewBox was replaced with a small size PC and a monitor. The viewer software suitable for radiotherapy was developed to maximize the benefit of digital image, and as the result the convenience and the effectiveness was improved. It has two windows to display two different images in the same time and equipped various search capability, contouring, window leveling, image resizing, translation, rotation and registration functions. In order to avoid any discontinuance of the treatment while the transition to digital image, the film and the CR was used together for 1 week, and then the film developer was removed. Since then the CR System has been operated stably for 2 months, and the various requests from users have been reflected to improve the system.

Introducción: El programa de código abierto OsiriX para MAC OS X® se presenta como una herramienta útil en el manejo de imágenes tomográficas para el diagnóstico y planificación preoperatoria en pacientes con fracturas del esqueleto facial. Material y métodos: Se realizó tomografía axial a 124 pacientes con fracturas faciales en el Servicio de Cirugía Maxilofacial y Reconstructiva del Hospital de Traumatología y Ortopedia Lomas Verdes. La información tomográfica en formato DICOM fue grabada en discos compactos y analizada en una computadora portátil Macintosh® con el programa OsiriX. Se realizó reconstrucción multiplanar y tridimensional y se compararon los hallazgos transoperatorios con la imágenes. Resultados: El 96.5 % de las imágenes coincidió con las reconstrucciones en el programa; solo 3.5 % presentó algún grado de discordancia por distorsiones en el estudio, secundarias a la presencia de proyectiles de arma de fuego y arcos férula de Erich. Conclusiones: Basados en los resultados, el programa OsiriX es una herramienta útil para el diagnóstico y planificación preoperatoria en pacientes con fracturas faciales. Además, evita la pérdida de información en el proceso de selección de las imágenes por el personal de radiología.

BACKGROUND: OsiriX, a Mac OS X-based open source program, is presented as a useful tool to process tomographic images for diagnosis and preoperative planning in patients with facial fractures. METHODS: CT scans were performed on 124 patients with facial fractures treated at the Department of Maxillofacial and Reconstructive Surgery of the Hospital de Traumatología y Ortopedia "Lomas Verdes" in Mexico City. Information obtained was recorded in DICOM format in CDs and processed in a Macintosh laptop with OsiriX software, doing multiplanar and 3D reconstructions. Surgical findings were compared to the images obtained by the software. RESULTS: Of the surgical findings, 96.5% matched with the OsiriX images. Only 3.5% of the OsiriX images were not consistent because of distortion or artifacts in the CT due to firearm projectiles and Erich arch bars near the involved area. CONCLUSIONS: Based on the results obtained, the authors consider that the OsiriX software is a useful tool for diagnosis and preoperative planning in patients with facial fractures. Furthermore, it prevents the loss of information due to the process of image selection by the radiology staff.

Measurement of Femoral Anteversion in the PACS Image Viewer / 대한의료정보학회지

The measurement of the femoral anteversion is an important factor in the practice of orthopedic surgery. The anteversion is measured by means of the axis of head and neck of the femur. In this study, widely used computed tomography method of measuring anteversion was tested on femoral necks of patients. Measurement by the manual method and image viewer of computed tomography to determine the anteversion of femoral head were carried out on both femurs. In January and February 2001, 30 patients 3 to 6 years of age were randomly selected from Seoul National University Hospital. The purpose of this paper was to introduce a new method to measure femoral anteversion angle utilizing image viewer program. This new method was more accurate and convenient than the conventional manual method. In conclusion, PACS of image viewer program was statistically more reliable in determining the angle of the femoral anteversion.

Implementation of the Bitmap Image File format for Dental Image Management / 대한의료정보학회지

Generally, PACS(Picture Archiving and Communication System) play an important role in the patient care support system of the HIS(Hospital Information System). In the dental PACS, image search and storage is very difficult without standardized DBI(Dental Bitmap Image) file format and view browser because each of the X-Ray instrument and the other image use various image file such as BMP, GIF, TIFF, PCX etc. We proposed the DBI for fast review, classification, storage and transmission of the dental image. It is based on personal computer environment. Using the thumbnail in the DBI, we made image files such as a type of album and operated on PC. We implemented DBI file format that include the DBI viewer and slide show application and other function of fundamental PACS by means of visual C++ and Windows API(Application Programming Interface). This program is consisted of three parts: First, convert the various image file format into DBI file format so as to integrated medical image file format. Second, additional descriptor such as patient name or necessary information to image file and management image file format. Second, additional descriptor such as patient name or necessary information to image file and management image file using patient information or date. Third, execution of the image of the image edit and image enhancement and image copression. Beside this Program Provide GUI interface for user's facility.

Development of Asymmetric Satellite Data Communication System and Evaluation Compared to Conventional terrestrial Network / 대한의료정보학회지

We developed the Tele-PACS of radiology, which uses the communication network as asymmetric satellite data communication system. The asymmetric satellite data communication system uses receive-only satellite links for data delivery and PSTN(Public Switched Telephone Network) modem or N-ISDN(Narrow-band Integrate Services Digital Network) for communication. The satellite communication linking we implemented showed the very high-speed performance compared to the terrestrial linking such as 28.8 kbps modem linking or 56Kbps linking. The satellite linking was 5-10 times faster than the terrestrial linking on the average. We developed the down-link system of satellite and the medical collaborative tools and the Web-based Image-viewer. We concluded that 1) Satellite networking is currently the cheapest and fastest solution for internet access. 2) Web-based Image-Viewer enables small size hospitals in rural area to connect to the central PACS easily and to retrieve the image data reliably. 3) The suggested teleradiology system using satellite networking could be adequate to the fast telemedicine and telecare for rural hospitals especially located in geographically isolated areas such as islands.
