Cyclic estrogen and progesterone during instrumental acquisition contributes to habit formation in female rats.

Habit formation is thought to involve two parallel processes that are mediated by distinct neural substates: one that suppresses goal-directed behavior, and one that facilitates stimulus-response (S-R) learning, which underscores habitual behavior. In previous studies we showed that habitual responding emerges early during instrumental training in gonadally-intact female, compared to male, rats. The present study aimed to determine the role of ovarian hormones during instrumental acquisition in the transition from goal-directed to habitual behavior in female rats.

Less-favourable prognosis for low-risk endometrial cancer patients with a discordant pre- versus post-operative risk stratification.

Background: Pre-operative risk stratification based on endometrial sampling determines the extent of surgery for endometrial cancer (EC). We investigated the concordance of pre- and post-operative risk stratifications and the impact of discordance on survival.

Methods: Patients diagnosed with EC within the first 6 months of the years 2005-2014 were selected from the Netherlands Cancer Registry (N = 7875).

Patient satisfaction in treatment for cervical pathology.

This study aimed to analyse the satisfaction levels of patients treated for cervical dysplasia. At the Orbis Medical Center, all cases of abnormal cervical cytology are referred for colposcopy; however, there are three possible routings for patients: i) Patients are informed by the gynecologist about the colposcopy in a visit to the outpatient clinic, and colposcopy is planned in a second visit; ii) patients are informed by the gynecologist immediately before the colposcopy (a single visit); or iii) patients are called by a nurse practitioner 1-2 weeks prior to the colposcopy. The nurse practitioner informs patients about their Pap smear result, the colposcopy procedure and the follow-up (single visit plus telephone conversation).

Should we centralise care for the patient suspected of having ovarian malignancy?

Objectives: Outcome of ovarian cancer is better when surgery is provided by a gynaecological oncologist than by a general gynaecologist. However, when all patients with an adnexal mass have to be operated by gynaecological oncologists, this requires a change in the organisation of care, which generates additional costs. In this study, we assess the costs and effects of centralised and regular care for women with an ovarian malignancy in the Netherlands.
