Background One of the challenges of robotic gynecologic surgery is the appropriate traction of the organs and other structures surrounding the surgical field. Methods We developed a novel traction device, VESOPASTA, that can be used for organ traction during robotic gynecologic surgery. This study describes the utility and the safety of the use of VESOPASTA for ureteral traction during robotic-assisted laparoscopic radical hysterectomy in five cervical cancer patients. Results Ureteral suspension was successfully and safely performed using VESOPASTA during robotic-assisted laparoscopic radical hysterectomy in cervical cancer patients without causing any complications. The average time required for this procedure was less than 5 min. Conclusions We have developed a novel device, VESOPASTA, which can be used for organ traction during robotic surgery. This new device allows easy ureteral traction, facilitate the identification of ureter and prevent ureteral injuries during robotic-assisted laparoscopic radical hysterectomy. © 2020 by JSLS, Journal of the Society of Laparoscopic & Robotic Surgeons.Diffusion MRI (dMRI), while powerful for characterization of tissue microstructure, suffers from long acquisition time. In this paper, we present a method for effective diffusion MRI reconstruction from slice-undersampled data. Instead of full diffusion-weighted (DW) image volumes, only a subsample of equally-spaced slices need to be acquired. We show that complementary information from DW volumes corresponding to different diffusion wavevectors can be harnessed using graph convolutional neural networks for reconstruction of the full DW volumes. The experimental results indicate a high acceleration factor of up to 5 can be achieved with minimal information loss.Aims This study describes when and how adolescents engage with their fast-moving and dynamic digital environment as they go about their daily lives. We illustrate a new approach - screenomics - for capturing, visualizing, and analyzing screenomes, the record of individuals' day-to-day digital experiences. Sample Over 500,000 smartphone screenshots provided by four Latino/Hispanic youth, age 14-15 years, from low-income, racial/ethnic minority neighborhoods. Method Screenomes collected from smartphones for one to three months, as sequences of smartphone screenshots obtained every five seconds that the device is activated, are analyzed using computational machinery for processing images and text, machine learning algorithms, human-labeling, and qualitative inquiry. Findings Adolescents' digital lives differ substantially across persons, days, hours, and minutes. Screenomes highlight the extent of switching among multiple applications, and how each adolescent is exposed to different content at different times for different durations - with apps, food-related content, and sentiment as illustrative examples. Implications We propose that the screenome provides the fine granularity of data needed to study individuals' digital lives, for testing existing theories about media use, and for generation of new theory about the interplay between digital media and development.Parent-directed marketing strategies have great potential to promote the utilization of therapy by adolescents with or at risk of substance-related problems. click here The extent to which marketing strategies should be tailored to parents of adolescents with various presenting problems - such as substance use, mental health, and legal involvement - is unknown. The current study represents a secondary analysis of a direct-to-consumer (DTC) marketing survey, which used a well-established framework called the Marketing Mix to solicit parent preferences about marketing across three dimensions Promotion (i.e., how parents prefer to receive information); Place (i.e., where parents prefer to receive therapy); and Price (i.e., how much parents are willing to pay and how far parents are willing to travel). Four-hundred eleven parents of 12- to 19-year-old adolescents (51% girls, 82% Non-Hispanic White) completed the survey and answered five questions spanning Promotion, Price, and Place dimensions of the Marketing Mix. A subsample of 158 parents also reported on their actual therapy-seeking behavior, allowing us to report on both parents' ideal and actual experiences. We explored the extent to which parent preferences varied as a function of adolescent substance use, externalizing, internalizing, and legal problems. Bivariate analyses and multivariate logistic regressions were used to examine which of these variables were associated with parents' responses to specific survey items. Analyses confirmed that both parent preferences and parents' actual therapy-seeking behavior varied as a function of adolescent problems. Recommendations are offered for professional psychologists to use DTC marketing strategies to connect with adolescents in need of services.Dental composites are used as restorative materials to replace tooth structure after the removal of caries, shaping, covering teeth for esthetic purposes and as adhesives. Dentists spend more time replacing existing restorations that fail than they do placing new restorations. Tooth colored restorations are difficult to differentiate from the surrounding tooth structure making them challenging to remove completely without incidental removal of healthy tooth structure. Previous studies have demonstrated that CO2 lasers in conjunction with spectral feedback can be used to selectively remove composite from tooth surfaces. In addition, we assembled a system feasible for clinical use that incorporates a spectral feedback system, scanning system, articulating arm and a clinical handpiece and subsequently evaluated the performance of that system on extracted teeth. The purpose of this study was to test this system in vivo to demonstrate its efficacy relative to dental clinicians. Eight test subjects with premolar teeth scheduled for extraction for orthodontic reasons had bilateral premolars prepared with small occlusal cavity preparations and filled with dental composite. The laser scanning system was used to remove the composite from one of the preparations and a dental handpiece was used to remove the composite from the other. Cross polarization optical coherence tomography was used to measure the volume of the preparation before and after composite placement and removal. There was no significant difference in the loss of enamel and residual composite between the laser and the handpiece. This study demonstrated that a computer controlled spectral guided CO2 laser scanning system can be used in vivo to selectively remove composite from tooth surfaces.
