Measles-mumps-rubella vaccine at 6 months of age, immunology, and childhood morbidity in a high-income setting: study protocol for a randomized controlled trial.

Background: Measles is a highly contagious and serious infection. Before the introduction of vaccination, measles caused yearly epidemics putting vulnerable children at risk of brain damage and death. Despite safe and cost-effective vaccines, measles remains a leading cause of death in children globally.

Instructor feedback versus no instructor feedback on performance in a laparoscopic virtual reality simulator: a randomized educational trial.

Background: Several studies have found a positive effect on the learning curve as well as the improvement of basic psychomotor skills in the operating room after virtual reality training. Despite this, the majority of surgical and gynecological departments encounter hurdles when implementing this form of training. This is mainly due to lack of knowledge concerning the time and human resources needed to train novice surgeons to an adequate level.

Effect of virtual reality training on laparoscopic surgery: randomised controlled trial.

Objective: To assess the effect of virtual reality training on an actual laparoscopic operation.

Design: Prospective randomised controlled and blinded trial.

Setting: Seven gynaecological departments in the Zeeland region of Denmark.

Objective assessment of surgical competence in gynaecological laparoscopy: development and validation of a procedure-specific rating scale.

Objective: The purpose of this study was to develop a global- and a procedure-specific rating scale based on a well-validated generic model (objective structured assessment of technical skills) for assessment of technical skills in laparoscopic gynaecology. Furthermore, we aimed to investigate the construct validity and the interrater agreement (IRA) of the rating scale. We investigated both the gamma coefficient (Kendall's rank correlation), which is a measure of the strength of dependence between observations, and the kappa value for each of the ten individual items included in the rating scale.

Ultrasound characteristics and histological dating of the endometrium in a natural cycle in infertile women compared with fertile controls.

Objective: To compare endometrial dating and ultrasound texture in a natural cycle before IVF and relate these to outcome and to fertile references.

Design: Prospective study with a fertile reference group.

Setting: Four university IVF clinics.
