RESUMO

BACKGROUND: Our objective was to assess the impact of incorporating videos in a behaviorally anchored performance rating scale on the inter-rater reliability (IRR) of expert, intermediate and novice raters. METHODS: The Intra-corporeal Suturing Assessment Tool (ISAT) was modified to include short video clips demonstrating poor, average, and expert performances. Blinded raters used this tool to assess videos of trainees performing suturing on a porcine model. Three attending surgeons, 4 residents, and 4 novice raters participated; no rater training was provided. The IRR was then compared among rater groups. RESULTS: The IRR using the modified ISAT was high at 0.80 (p < 0.001). Ratings were significantly correlated with trainee objective suturing scores for all rater groups (experts: R = 0.84, residents: R = 0.81, and novices: R = 0.69; p < 0.001). CONCLUSIONS: Incorporating video anchors (to define performance) in the ISAT led to high IRR and enabled novices to achieve similar consistency in their ratings as experts.

RESUMO

Engineered structures in the open ocean are becoming more frequent with the expansion of the marine renewable energy industry and offshore marine aquaculture. Floating engineered structures function as artificial patch reefs providing novel and relatively stable habitat structure not otherwise available in the pelagic water column. The enhanced physical structure can increase local biodiversity and benefit fisheries yet can also facilitate the spread of invasive species. Clear evidence of any ecological consequences will inform the design and placement of structures to either minimise negative impacts or enhance ecosystem restoration. The development of rapid, cost-effective and reliable remote underwater monitoring methods is crucial to supporting evidence-based decision-making by planning authorities and developers when assessing environmental risks and benefits of offshore structures. A novel, un-baited midwater video system, PelagiCam, with motion-detection software (MotionMeerkat) for semi-automated monitoring of mobile marine fauna, was developed and tested on the UK's largest offshore rope-cultured mussel farm in Lyme Bay, southwest England. PelagiCam recorded Atlantic horse mackerel (Trachurus trachurus), garfish (Belone belone) and two species of jellyfish (Chrysaora hysoscella and Rhizostoma pulmo) in open water close to the floating farm structure. The software successfully distinguished video frames where fishes were present versus absent. The PelagiCam system provides a cost-effective remote monitoring tool to streamline biological data acquisition in impact assessments of offshore floating structures. With the rise of sophisticated artificial intelligence for object recognition, the integration of computer vision techniques should receive more attention in marine ecology and has great potential to revolutionise marine biological monitoring.

RESUMO

Background and objectives: The objective of this study was to contribute to the evaluation of the newborn (NB) cry as a means of communication and diagnosis. Materials and Methods: The study implied the recording of the spontaneous cry of 101 NBs with no intrapartum events (control sample), and of 72 NBs with nuchal cord (study sample) from the "Bega" University Clinic of Obstetrics-Gynecology and Neonatology of Timisoara, Romania. The sound analysis was based upon: Imagistic highlighting methods, descriptive statistics, and data mining techniques. Results: The differences between the cry of NBs with no intrapartum events and that of NBs affected by nuchal cord are statistically significant regarding the volume unit meter (VUM) (p = 0.0021) and the peak point meter (PPM) (p = 0.041). Conclusions: While clinically there are no differences between the two groups, the cry recorded from the study group (nuchal cord group) shows distinctive characteristics compared to the cry recorded from the control group (eventless intrapartum NBs group).

RESUMO

Compound eyes, also known as insect eyes, have a unique structure. They have a hemispheric surface, and a lot of single eyes are deployed regularly on the surface. Thanks to this unique form, using the compound images has several advantages, such as a large field of view (FOV) with low aberrations. We can exploit these benefits in high-level vision applications, such as object recognition, or semantic segmentation for a moving robot, by emulating the compound images that describe the captured scenes from compound eye cameras. In this paper, to the best of our knowledge, we propose the first convolutional neural network (CNN)-based ego-motion classification algorithm designed for the compound eye structure. To achieve this, we introduce a voting-based approach that fully utilizes one of the unique features of compound images, specifically, the compound images consist of a lot of single eye images. The proposed method classifies a number of local motions by CNN, and these local classifications which represent the motions of each single eye image, are aggregated to the final classification by a voting procedure. For the experiments, we collected a new dataset for compound eye camera ego-motion classification which contains scenes of the inside and outside of a certain building. The samples of the proposed dataset consist of two consequent emulated compound images and the corresponding ego-motion class. The experimental results show that the proposed method has achieved the classification accuracy of 85.0%, which is superior compared to the baselines on the proposed dataset. Also, the proposed model is light-weight compared to the conventional CNN-based image recognition algorithms such as AlexNet, ResNet50, and MobileNetV2.

RESUMO

Introducción y objetivo: El éxito de un colgajo microquirúrgico depende, entre otras cosas, de una correcta técnica de la anastomosis, siendo la experiencia preoperatoria del cirujano directamente proporcional a la tasa de supervivencia del mismo. El uso de animales vivos es el modelo estándar para el entrenamiento en Microcirugía. Sin embargo, implica un alto costo y una necesidad de recursos. Existen diferentes alternativas para el entrenamiento de habilidades microquirúrgicas pero sigue siendo necesario tener un microscopio y un lugar físico para realizar las prácticas. El uso de teléfonos inteligentes en Cirugía Plástica toma cada vez más relevancia y hoy en día son varias sus aplicaciones también como alternativa al microscopio. El objetivo de este trabajo es proponer un modelo alternativo para la enseñanza microquirúrgico utilizando un teléfono inteligente como sustituto del microscopio. Material y método: Creamos una plataforma de trabajo sobre una mesa con un soporte de celular con brazo flexible al costado de la misma. Para reemplazar el microscopio utilizamos un teléfono inteligente Apple 8s Plus(R) que permite un zoom digital de hasta 10X y la posibilidad de grabar videos en 4k y alta definición. Para las pruebas planteamos 3 ejercicios con modelos inanimados de dificultad creciente: el deshilachado de las fibras de una gasa, el armado de suturas en un guante de látex y la técnica de anastomosis vascular y/o nerviosa en una pata de pollo. Tomamos fotografías en las diferentes magnificaciones para comprobar la definición y la posibilidad de realizar anastomosis sobre diferentes plataformas. Resultados: Pudimos realizar los 3 ejercicios utilizando la máxima magnificación con una definición adecuada. Conclusiones: El teléfono inteligente permite realizar diferentes ejercicios microquirúrgicos con un adecuado nivel de magnificación y definición. Podría por tanto emplearse como sustituto y/o complemento del microscopio para una práctica más accesible y económica


Background and objective. A successful outcome in Microsurgery depends, among others, on the performance of technically perfect microvascular anastomosis, being the operative experience the single most critical factor in avoiding free flap failure. Using living animals represents the actual training standard. However, this implies high costs. Several nonliving models have been proposed as alternatives for the acquisition of basic skills. Nevertheless, a microscope is needed to practice. The use of smartphones in Plastic Surgery is well documented. The purpose of this article is to describe the possibility of using the smartphone to replace an operating microscope in Microsurgery training. Methods. A test platform was created. A phone holder was placed on the side of a table, such that it could be comfortably reached from the test platform. The microscope was replaced with a smartphone Apple 8s Plus(R) with a digital 10x zoom. Three exercises in non living models were used for the test: gauze, latex glove and chicken tight. Photographs were taken to show the smartphone definition and the applicability to perform Microsurgery anastomosis. Results. All exercises could be performed in the maximum magnification with adequate definition. Conclusions. The use of smartphones as a microsurgery model presented in this study could be applied to basic Microsurgery education and also used as an alternative training model owing to its easy application, easy accessibility and low cost

RESUMO

Fast object tracking in real time allows convenient tracking of very large numbers of animals and closed-loop experiments that control stimuli for many animals in parallel. We developed MARGO, a MATLAB-based, real-time animal tracking suite for custom behavioral experiments. We demonstrated that MARGO can rapidly and accurately track large numbers of animals in parallel over very long timescales, typically when spatially separated such as in multiwell plates. We incorporated control of peripheral hardware, and implemented a flexible software architecture for defining new experimental routines. These features enable closed-loop delivery of stimuli to many individuals simultaneously. We highlight MARGO's ability to coordinate tracking and hardware control with two custom behavioral assays (measuring phototaxis and optomotor response) and one optogenetic operant conditioning assay. There are currently several open source animal trackers. MARGO's strengths are 1) fast and accurate tracking, 2) high throughput, 3) an accessible interface and data output and 4) real-time closed-loop hardware control for for sensory and optogenetic stimuli, all of which are optimized for large-scale experiments.

RESUMO

Failure to secure the airway is an important cause of morbidity and mortality during resuscitations. We compared the rate of successful intubation of the King Vision™ aBlade™ channeled and non-channeled video laryngoscopes, and McGRATH™ MAC video laryngoscope when used by junior doctors to intubate a simulated difficult airway in an out-of-hospital setting. 105 junior doctors were recruited in a crossover study to perform tracheal intubation with the three video laryngoscopes on a simulated difficult airway using the SimMan® 3G manikin. Primary outcome was the rate of successful intubations. Secondary outcomes were time-to-visualization, time-to-intubation and ease of use. Rates of successful intubations were higher for King Vision channeled and McGrath compared to the King Vision non-channeled (85.7% and 82.9% respectively versus 24.8%; p<0.001). Amongst the participants who had successful intubations, King Vision channeled and McGrath had shorter mean time-to-intubation compared to the King Vision non-channeled (41.3±20.3s and 38.5±18.7s respectively versus 53.8±23.8s, p<0.004;). There was no significant difference in the rate of successful intubation and mean time-to-intubation between King Vision channeled and McGrath. The King Vision channeled and McGrath video laryngoscopes demonstrated superior intubation success rates compared to King Vision non-channeled laryngoscope when used by junior doctors for intubating simulated difficult airway in an out-of-hospital setting. We postulated that the presence of a guidance channel in the King Vision channeled laryngoscope and the familiarity of the blade curvature and handling of the McGrath could have accounted for their improved intubation success rates.

RESUMO

In real world scenarios, the task of estimating heart rate (HR) using video plethysmography (VPG) methods is difficult because many factors could contaminate the pulse signal (i.e., a subjects' movement, illumination changes). This article presents the evaluation of a VPG system designed for continuous monitoring of the user's heart rate during typical human-computer interaction scenarios. The impact of human activities while working at the computer (i.e., reading and writing text, playing a game) on the accuracy of HR VPG measurements was examined. Three commonly used signal extraction methods were evaluated: green (G), green-red difference (GRD), blind source separation (ICA). A new method based on an excess green (ExG) image representation was proposed. Three algorithms for estimating pulse rate were used: power spectral density (PSD), autoregressive modeling (AR) and time domain analysis (TIME). In summary, depending on the scenario being studied, different combinations of signal extraction methods and the pulse estimation algorithm ensure optimal heart rate detection results. The best results were obtained for the ICA method: average RMSE = 6.1 bpm (beats per minute). The proposed ExG signal representation outperforms other methods except ICA (RMSE = 11.2 bpm compared to 14.4 bpm for G and 13.0 bmp for GRD). ExG also is the best method in terms of proposed success rate metric (sRate).

RESUMO

AIM: To explore the conditions that may influence the implementation of an interactive mobile application (app) and an intelligent videomonitoring system (IVS) in nursing homes (NHs) and the ethical challenges of their use. BACKGROUND: There is a lack of knowledge about implementing technologies in NHs and the ethical challenges that might arise. In past studies, nursing care teams expressed the need for technologies offering clinical support. Technologies like an IVS and an app could prove useful in NHs to prevent and manage falls and responsive behaviours. DESIGN: An exploratory qualitative study was conducted with care managers, family caregivers and formal caregivers in five NHs. METHODS: Each participant was shown a presentation of a potential app and a short video on an IVS. It was followed by an individual semi-structured interview. A conventional content analysis was performed. FINDINGS: Potential users found it would be possible to implement these technologies in NHs even if resistance could be expected. To facilitate adoption and achieve clinical benefits, the implementation of technologies should be pilot-tested, and coaching activities should be planned. Ethical risks were considered already present in NHs even without technologies, for example, risks to privacy. Strategies were proposed, for instance, to adapt the code of ethics and procedures. Some potential prejudices about the interest and abilities of older staff, nurses' aides, and family caregivers to use technology were identified. CONCLUSIONS: Through rigorous and ethical implementation, technologies supporting clinical care processes could benefit older people living in NHs, as well as their relatives and the staff. IMPLICATIONS FOR PRACTICE: Various strategies are proposed to successfully implement technologies. Effort should be made to avoid prejudices during implementation, and procedures should be adapted to mitigate possible ethical challenges.

RESUMO

Recording surgical procedures is of value for teaching and training in residency and fellowship programs. Operating external ophthalmic surgeries is not as easy as recording intraocular surgeries. In this communication, we describe the use of a video recorder mounted on a flexible tripod (Gorillapod®), a commonly available photography accessory; which is fixed to an IV fluid stand. This set up was used to record external ophthalmic surgeries and the recorded videos were of high quality in terms of stability and required no change in surgical technique to ensure that the area of interest was in focus. In our experience, early results show that a flexible tripod offers an economical mount for recording external surgeries with reproducible results.

RESUMO

Sleep is a critically important dimension of primate behavior, ecology, and evolution, yet primate sleep is under-studied because current methods of analyzing sleep are expensive, invasive, and time-consuming. In contrast to electroencephalography (EEG) and actigraphy, videography is a cost-effective and non-invasive method to study sleep architecture in animals. With video data, however, it is challenging to score subtle changes that occur in different sleep states, and technology has lagged behind innovations in EEG and actigraphy. Here, we applied Eulerian videography to magnify pixels relevant to scoring sleep from video, and then compared these results to analyses based on actigraphy and standard infrared videography. We studied four species of lemurs (Eulemur coronatus, Lemur catta, Propithecus coquereli, Varecia rubra) for 12-h periods per night, resulting in 6480 1-min epochs for analysis. Cramer's V correlation between actigraphy-classified sleep and infrared videography-classified sleep revealed consistent results in eight of the nine 12-h videos scored. A sample of the infrared videography was then processed by Eulerian videography for movement magnification and re-coded. A second Cramer's V correlation analysis, between two independent scorers coding the same Eulerian-processed video, found that interobserver agreement among Eulerian videography increased sleep vs. awake, NREM, and REM classifications by 7.1%, 46.7%, and 34.3%, respectively. Furthermore, Eulerian videography was more strongly correlated with actigraphy data when compared to results from standard infrared videography. The increase in agreement between the two scorers indicates that Eulerian videography has the potential to improve the identification of sleep states in lemurs and other primates, and thus to expand our understanding of sleep architecture without the need for EEG.

RESUMO

Continuous sampling provides the most complete data set for behavioral research; however, it often requires a prohibitive investment of time and labor. The objectives of this study were to validate behavioral observation methods of young broiler chickens using 1) 7 scan sampling intervals (0.5, 1, 3, 5, 10, 15, and 30 min) and 2) an automated tracking software program (EthoVision XT 14) compared to continuous behavioral observation, considered the gold standard for behavior observation. Ten 19-day-old Ross 708 broiler cockerels were included in this study. All behavior was video recorded over an 8-h period, and data were collected using a continuous sampling methodology. The same video files were utilized for analysis for scan sampling and automated tracking software analysis. For both analyses, the following criteria were used to identify which method accurately reflected the true duration and frequency for each behavior, as determined by continuous observation: R2 ≥ 0.9, slope was not different from 1 (P > 0.05), and intercept was not different from 0 (P > 0.05). Active, eating, drinking, and maintenance behaviors were accurately estimated with 0.5-min scan sample intervals. Active, inactive, eating, and maintenance behaviors were accurately estimated with 1-min scan sample intervals. Inactive behavior was accurately estimated with 5-min scan sample intervals. The remainder of sampling intervals examined did not provide accurate estimates, and no scan sampling interval accurately estimated the number of behavior bouts. The automated tracking software was able to accurately detect true duration of inactive behavior but was unable to accurately detect activity. The results of this study suggest that high-frequency behaviors can be accurately observed with instantaneous scan sampling up to 1-min intervals. Automated tracking software can accurately identify inactivity in young broiler chickens, but further behavior identification will require refinement.

RESUMO

This chapter provides an ImageJ/Fiji automated macro approach to remove the vitelline membrane autofluorescence in live Drosophila embryo movies acquired in a 4D (3D plus time) fashion. The procedure consists in a segmentation pipeline that can cope with different relative intensities of the vitelline membrane autofluorescence, followed by a developed algorithm that adjusts the extracted outline selection to the shape deformations that naturally occur during Drosophila embryo development. Finally, the fitted selection is used to clear the external glowing halo that, otherwise, would obscure the visualization of the internal embryo labeling upon projection or 3D rendering.

RESUMO

Video recording of surgical procedures is an important tool for surgical education, performance enhancement, and error analysis. Technology for video recording open surgery, however, is limited. The objective of this article is to provide an overview of the available literature regarding the various technologies used for intraoperative video recording of open surgery. A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines using the MEDLINE, Cochrane Central, and EMBASE databases. Two authors independently screened the titles and abstracts of the retrieved articles, and those that satisfied the defined inclusion criteria were selected for a full-text review. A total of 2275 publications were initially identified, and 110 were included in the final review. The included articles were categorized based on type of article, surgical subspecialty, type and positioning of camera, and limitations identified with their use. The most common article type was primary-technical (29%), and the dominant specialties were general surgery (22%) and plastic surgery (18%). The most commonly cited camera used was the GoPro (30%) positioned in a head-mount configuration (60%). Commonly cited limitations included poor video quality, inadequate battery life, light overexposure, obstruction by surgical team members, and excessive motion. Open surgery remains the mainstay of many surgical specialties today, and technological innovation is absolutely critical to fulfill the unmet need for better video capture of open surgery. The findings of this article will be valuable for guiding future development of novel technology for this purpose.

RESUMO

New-onset paroxysmal events in patients over 60 years of age are often diagnostically challenging owing to atypical presentation. Recurrent falls and transient states of confusion are especially common in the elderly population, yet their causes often remain undiagnosed due to concomitant cognitive deficits and motor impairments. We present an elderly patient with newly occurring 'blackouts' without obvious triggers and transient states of confusion for which he was amnestic. All neurological exams including brain MRI scan and routine electroencephalography (EEG) were normal. Long-term ECG monitoring using an event recorder captured an asystole during a habitual episode, leading to the diagnosis of syncope and pacemaker implantation. A subsequent video EEG monitoring performed due to ongoing unexplained confusional states revealed both bradycardia and long-lasting confusional states to be caused by unrecognised temporal lobe seizures. Ictal video EEG monitoring may play a crucial role in establishing a diagnosis of atypical temporal lobe seizures in the elderly.

RESUMO

Background: Improvements in personal technology have made video recording for teaching and assessment of surgical skills possible. Objective: This study compared 5 personal video-recording devices based on their utility (image quality, hardware, mounting options, and accessibility) in recording open surgical procedures. Methods: Open procedures in a simulated setting were recorded using smartphones and tablets (MOB), laptops (LAP), sports cameras such as GoPro (SC), single-lens reflex cameras (DSLR), and spy camera glasses (SPY). Utility was rated by consensus between 2 investigators trained in observation of technology using a 5-point Likert scale (1, poor, to 5, excellent). Results: A total of 150 hours of muted video were reviewed with a minimum 1 hour for each device. Image quality was good (3.8) across all devices, although this was influenced by the device-mounting requirements (4.2) and its proximity to the area of interest. Device hardware (battery life and storage capacity) was problematic for long procedures (3.8). Availability of devices was high (4.2). Conclusions: Personal video-recording technology can be used for assessment and teaching of open surgical skills. DSLR and SC provide the best images. DSLR provides the best zoom capability from an offset position, while SC can be placed closer to the operative field without impairing sterility. Laptops provide best overall utility for long procedures due to video file size. All devices require stable recording platforms (eg, bench space, dedicated mounting accessories). Head harnesses (SC, SPY) provide opportunities for "point-of-view" recordings. MOB and LAP can be used for multiple concurrent recordings.

RESUMO

Intubation is frequently required for patients in the intensive care unit (ICU) but is associated with high morbidity and mortality mainly in emergency procedures and in the presence of severe organ failures. Improving the intubation procedure is a major goal for all ICU physicians worldwide, and videolaryngoscopy may play a relevant role.Videolaryngoscopes are a heterogeneous entity, including Macintosh blade-shaped optical laryngoscopes, anatomically shaped blade without a tube guide and anatomically shaped blade with a tube guide, which might have theoretical benefits and pitfalls. Videolaryngoscope/videolaryngoscopy improves glottis view and allows supervision by an expert during the intubation process; however, randomized controlled trials in the ICU suggest that the systematic use of videolaryngoscopes for every intubation cannot yet be recommended, especially in non-expert hands. Nevertheless, a videolaryngoscope should be available in all ICUs as a powerful tool to rescue difficult intubation or unsuccessful first-pass laryngoscopy, especially in expert hands.The use of associated devices such as bougie or stylet, glottis view needed (full vs incomplete) and patient position during intubation (ramped, sniffed position) should be further evaluated.

RESUMO

Introduction: Knowledge and skill development related to communication must incorporate both affective and behavioral components, which are often difficult to deliver in a learning activity. Using theater techniques and principles can provide medical educators with tools to teach communication concepts. Methods: This 75-minute faculty development workshop presents a variety of techniques from theater and adapts them for use in medical education. Using examples related to diversity and inclusion, this session addresses general educational and theater principles, role-play, sociodrama, applied improvisation, and practical aspects of involving theater partners. The session materials include a PowerPoint presentation with facilitator notes, interactive activities to demonstrate each modality, and an evaluation. The sessions can be extended to longer formats as needed. Results: Forty-five participants at Learn Serve Lead 2016: The AAMC Annual Meeting attended the 75-minute session. We emailed 32 participants 5 months after the conference, and eight responded. Participants reported that their confidence level in using theater techniques as a tool for medical education increased from low-to-medium confidence presession to high confidence postsession. All survey respondents who were actively teaching said they had made changes to their teaching based on the workshop. All commented that they appreciated the active learning in the session. Many indicated they would appreciate video or other follow-up resources. Discussion: Principles and techniques from theater are effective tools to convey difficult-to-teach concepts related to communication. This workshop presents tools to implement activities in teaching these difficult concepts.
