Predicting the number of oocytes retrieved from controlled ovarian hyperstimulation with machine learning.

Study Question: Can machine learning predict the number of oocytes retrieved from controlled ovarian hyperstimulation (COH)?

Summary Answer: Three machine-learning models were successfully trained to predict the number of oocytes retrieved from COH.

What Is Known Already: A number of previous studies have identified and built predictive models on factors that influence the number of oocytes retrieved during COH. Many of these studies are, however, limited in the fact that they only consider a small number of variables in isolation.

A time-lapse embryo dataset for morphokinetic parameter prediction.

One of the most common treatments for infertile couples is In Vitro Fertilization (IVF). It consists of controlled ovarian hyperstimulation, followed by ovum pickup, fertilization, and embryo culture for 2-6 days under controlled environmental conditions, leading to intrauterine transfer or freezing of embryos identified as having a good implantation potential by embryologists. To allow continuous monitoring of embryo development, Time-lapse imaging incubators (TLI) were first released in the IVF market around 2010.

19 G nitinol needle versus 22 G needle for transduodenal endoscopic ultrasound-guided sampling of pancreatic solid masses: a randomized study.

Background: The aim of this prospective multicenter study was to compare a flexible 19 G needle with nitinol shaft (19 G Flex) with a standard 22 G needle for transduodenal endoscopic ultrasound (EUS)-guided sampling of pancreatic head tumors.

Methods: Patients with pancreatic head tumors requiring tissue diagnosis were randomized into two arms: puncture with either a 19 G Flex needle or a 22 G needle. The primary end point was diagnostic accuracy for malignancy.

Multicenter prospective evaluation of the express view reading mode for small-bowel capsule endoscopy studies.

Background:  Reducing the reading time of capsule endoscopy films is of high priority for gastroenterologists. We report a prospective multicenter evaluation of an "express view" reading mode (Intromedic capsule system).

Methods:  Eighty-three patients with obscure gastrointestinal bleeding were prospectively included in 10 centers.

Interest of submucosal dissection knife for endoscopic treatment of Zenker's diverticulum.

Background: Dual-Knife(®) (Olympus) and Hydride-Knife(®) are new needle knives frequently used for submucosal dissection because of their safety and precision. In this study we aimed to evaluate the efficacy and safety of such devices in the diverticulopexy by flexible endoscopy.

Methods: From February 2009 to March 2013, 42 patients (25 men), mean age 74.
