BACKGROUND: Direct-to-consumer telemedicine is becoming part of mainstream medicine, but questions exist regarding the quality of care provided. We assessed antibiotic stewardship, one measure of quality, by comparing antibiotic prescription rates for acute respiratory infections (ARIs) between patients seen by telemedicine and patients seen in-person in two urban emergency departments (EDs). METHODS: In two urban EDs where low-acuity patients in the ED have the option of being seen by telemedicine rather than in-person, we analyzed telemedicine and in-person visits of patients ≥18 years who received ARI diagnoses between July 2016 and September 2017...

Information technology has stimulated efforts to reform teaching methods in dental education. Most of these efforts involve a shift from conventional mode to the more technology-savvy and student-centered approach. The aim of this study was to compare postgraduate dental students' academic performance using two teaching methodologies (video-based learning and blended module-based learning) in a biostatistics and research methodology course in a master's program at a dental college in India. This retrospective study involved two groups of students enrolled in the master's program with different years of admission: Group I in 2013-14 (n=80) and Group II in 2015-16 (n=80)...

Central place foraging theory (CPF) has been used to predict the optimal patch residence time for air-breathing marine predators in response to patch quality. Humpback whales (Megaptera novaeangliae) forage on densely aggregated prey, which may induce drastic change in prey density in a single feeding event. Thus, the decision whether to leave or stay after each feeding event in a single dive in response to this drastic change, should have a significant effect on prey exploitation efficiency. However, whether humpback whales show adaptive behavior in response to the diminishing prey density in a single dive has been technically difficult to test...

The continuous availability of cells with defined cell characteristics represents a crucial issue in the biopharmaceutical and cell therapy industry. Here, development of cell banks with a long-term stability is essential and ensured by a cryopreservation strategy. The strategy needs to be optimized for each cell application individually and usually comprises controlled freezing, storage at ultra-low temperature, and fast thawing of cells. This approach is implemented by the development of master and working cell banks...

We present the global deep video representation learning to video-based person reidentification (re-ID) that aggregates local 3-D features across the entire video extent. Existing methods typically extract frame-wise deep features from 2-D convolutional networks (ConvNets) which are pooled temporally to produce the video-level representations. However, 2-D ConvNets lose temporal priors immediately after the convolutions, and a separate temporal pooling is limited in capturing human motion in short sequences...

Videos are spatio-temporally rich in static to dynamic objects/scenes, sparse to dense, and periodic to non-periodic motions. Particularly, dynamic texture (DT) exhibits complex appearance and motion changes that remain challenge to deal with. This paper presents an energy optimization method for feature extraction and recognition in videos. For noise and background jitter, Tikhonov regularization (TR) with eigen-vector and Frenet-Serret formula based energy constraints is also proposed. Different periodicity of DT can be adapted by the time-varying number of learning temporal frames...

Laboratory-based retroreflective and magnetic scleral search-coil technologies are the current standards for collecting saccadometric data, but such equipment is costly and cumbersome. We have validated a novel, portable, high-speed video camera-based system (Exilim EX-FH20, Casio, Tokyo, Japan) for measuring saccade reaction time (RT) and error rate in a well-lit environment. This system would enable measurements of pro- and antisaccades in athletes, which is important because antisaccade metrics provide a valid tool for concussion diagnosis and determining an athlete's safe return to play...

Oculomotor dysfunction may originate from physical, physiological or psychological causes and may be a marker for schizophrenia or other disorders. Observational tests for oculomotor dysfunction are easy to administer, but are subjective and transient, and it is difficult to quantify deviations. To date, video-based eye tracking systems have not provided a contextual overview of gaze data that integrates the eye video recording with the stimulus and gaze data together with quantitative feedback of metrics in relation to typical values...

Drawing on 5 years of experience designing, producing, and disseminating video health education programs globally, we outline the process of creating accessible, engaging, and relevant video health education content using a community-based, human-centered design approach. We show that this approach can yield a new generation of interventions, which are better aligned with the needs and contexts of target communities. The participation of target communities and local stakeholders in the content production and design process fosters ownership of the content and increases the likelihood that the resulting intervention will resonate within its intended primary audience and be disseminated broadly...
