Negation detection in Dutch clinical texts: an evaluation of rule-based and machine learning methods.

When developing models for clinical information retrieval and decision support systems, the discrete outcomes required for training are often missing. These labels need to be extracted from free text in electronic health records. For this extraction process one of the most important contextual properties in clinical text is negation, which indicates the absence of findings.

Office hysteroscopic myomectomy without myoma extraction: A multicenter prospective study.

Objective: To evaluate the feasibility and safety of leaving the submucous myoma (SM) in the uterine cavity after office hysteroscopic enucleation.

Study Design: Prospective multicenter study including patients who had a single SM diagnosed by transvaginal ultrasounds with surgical indication. Office hysteroscopic enucleation of the SM was performed using a 5 mm continuous flow office hysteroscope with a 2.

Dysmorphic Uteri: Obstetric Results after Hysteroscopic Office Metroplasty in Infertile and Recurrent Pregnancy Loss Patients. A Prospective Observational Study.

To compare the obstetric results achieved after hysteroscopic office metroplasty (HOME-DU) in infertile and recurrent pregnancy loss (RPL) patients diagnosed with dysmorphic uterus, women hysteroscopically diagnosed with dysmorphic uterus who underwent uterine-enlargement metroplasty were prospectively enrolled from June 2016 until April 2020. Patients were followed up and obstetric outcomes were recorded (pregnancy and live birth rate). Sixty-three women (30 infertile; 33 RPL) were enrolled, of which 48 became pregnant post-HOME-DU, with an overall pregnancy rate of 76.

Hysteroscopy in pregnancy-related conditions: descriptive analysis in 273 patients.

Study Objective: To describe the feasibility of office hysteroscopy in patients with pregnancy-related problems such as retained trophoblastic tissue, persistent molar tissue, pregnancy with in situ intrauterine device (IUD), isthmocele, embryoscopy, and osseous metaplasia.

Design: Retrospective cohort chart review of use of hysteroscopy in 273 patients with pregnancy-related conditions (Canadian Task Force classification II-2).

Setting: University tertiary-care hospital.

Hysteroscopic dynamic assessment of the endometrium in patients treated with long-term tamoxifen.

Study Objective: To describe the evolutive endometrial hysteroscopic patterns in patients undergoing long-term tamoxifen treatment.

Design: Prospective analysis. Analysis of variance test with post hoc Bonferroni test and homogeneity test of percentages were used for hypothesis contrast between the groups.
