In our practice, there is a growing need to perform gastrostomy tube placement in infants and young children with feeding difficulties. To avoid possible complications arising from pull-through method (pull-through PEG) we began to perform a one-step endoscopic gastrostomy with a gastropexy device (push GT). This study aimed to evaluate the safety of this technique in infants and young children. In our study, 60 pull-through PEG and push GT procedures were retrospectively analysed in patients between 2.83 and 8.6 kg. We analysed the adverse events in both groups. Age, sex, weight, diagnosis, early (occurring ≤ 7 days after the procedure) and late (occurring > 7 days after the procedure) complications were compared in the two groups. Median follow-up duration was 12 months. Early minor complications occurred only in the push GT group, but this was not statistically significant. There was no significant difference between the groups regarding early major complications. Late minor complications were significantly more common in the push GT group. There were no late major complications in the push GT group, which is statistically significant. In infants and young children, push GT with a gastropexy device is a safe method to perform gastrostomy even in patients unsuitable for pull-through PEG placement.

PurposeTransverse patellar fractures (TPFs) are uncommon in athletes, and their treatment can be challenging. Stable fixation is commonly achieved by compression screw fixation and stainless steel cerclage wire, but this technique can be associated with complications like nonunion, infection and the need for early hardware removal. We used a combined tension-band (figure-of-eight) braided polyester and suture button technique to treat four athletes who presented with transverse patellar fractures. This technique has shown to be a valuable alternative to the classic technique and allows for adequate fracture compression, stability and union in TPF.MethodsUsing a tension-band braided polyester and suture button technique (Arthrex FibreTapeR&TightRopeR), we treated four athletes with transverse patellar fractures from September 2015 till January 2017. The polyester was looped over the four suture button fixation points and tensioned in a figure-of-eight fashion. The average age of the athletes was 26 years (range 17–36). Follow-up ranged from 5 to 21 months. All four patients were treated using the same surgical technique (minimally invasive surgery) with the same postoperative recovery and the same physiotherapy protocol.ResultsFull recovery using suture button adjustable loop fixation device was obtained in all four cases within 3 months after surgery, with fracture healing confirmed on postoperative radiographs. No patients required hardware removal. Potential problems with this technique can include bony tunnel malpositioning or soft tissue interpositioning underneath the suture buttons.ConclusionThe combination of a suture button fixation and a braided polyester tension-band technique has shown to be a valuable alternative to the fracture management of transverse patella fractures in athletes. This results in fracture healing, low risk of complications and no need for hardware removal.

IQUAFLOW is a new image quality framework that provides a set of tools to assess image quality. The user can add custom metrics that can be easily integrated. Furthermore, iquaflow allows to measure quality by using the performance of AI models trained on the images as a proxy. This also helps to easily make studies of performance degradation of several modifications of the original dataset, for instance, with images reconstructed after different levels of lossy compression; satellite images would be a use case example, since they are commonly compressed before downloading to the ground. In this situation, the optimization problem consists in finding the smallest images that provide yet sufficient quality to meet the required performance of the deep learning algorithms. Thus, a study with iquaflow is suitable for such case. All this development is wrapped in Mlflow: an interactive tool used to visualize and summarize the results. This document describes different use cases and provides links to their respective repositories. To ease the creation of new studies, we include a cookie-cutter repository. The source code, issue tracker and aforementioned repositories are all hosted on GitHub https://github.com/satellogic/iquaflow.
