Effect of Dynamic Light Application on Cognitive Performance and Well-being of Intensive Care Nurses.

Background: Exposure to bright light has alerting effects. In nurses, alertness may be decreased because of shift work and high work pressure, potentially reducing work performance and increasing the risk for medical errors.

Objectives: To determine whether high-intensity dynamic light improves cognitive performance, self-reported depressive signs and symptoms, fatigue, alertness, and well-being in intensive care unit nurses.

The impact of diagnosis and trait anxiety on psychological distress in women with early stage breast cancer: a prospective study.

Objectives: High trait anxiety (HTA) determines depressive symptoms and state anxiety in women with breast cancer (BC) or benign breast disease (BBD). Before implementing screening for psychological counselling in these women, it is important to evaluate whether high state anxiety and depressive symptoms are determined by (the threat of) having BC or solely by HTA. Therefore, we compared women with a lump in the breast with women with gallstone disease (GD).

Cancer or no cancer: the influence of trait anxiety and diagnosis on quality of life with breast cancer and benign disease: a prospective, longitudinal study.

Background: High trait anxiety (HTA) causes an impaired quality of life (QOL) and fatigue in women with breast cancer (BC) and benign breast disease (BBD). We examined whether the lowered QOL was determined solely by the personality characteristic HTA or by the combination of personality and diagnosis.

Methods: In a prospective longitudinal study, women with BC (n = 152), BBD (n = 205), or gallstone disease (GD) before laparoscopic cholecystectomy (n = 128) were included.

Trait anxiety predicts outcome 6 weeks after cholecystectomy. A prospective follow-up study.

Background: A substantial group of patients with gallstone disease experience negative outcome after surgical removal of the gallbladder (cholecystectomy). Early identification of these patients is important.

Purpose: The aim of the study is to identify predictors (clinical symptoms and trait anxiety) of negative symptomatic outcomes at 6 weeks after cholecystectomy.

Risk assessment in cholelithiasis: is cholecystectomy always to be preferred?

Background: As many patients with gallstone disease do not benefit from cholecystectomy, preoperative recognition of such high-risk patients is important. The aim of the study is to identify predictors of persisting symptoms at 6 months after cholecystectomy for patients with different preoperative symptomatology.

Method: Participants in this prospective study were consecutive patients (n = 172), age 18-65 years, with symptomatic cholelithiasis, undergoing a laparoscopic cholecystectomy.

Trait anxiety predicts unsuccessful surgery in gallstone disease.

Objective: To identify predictors of negative symptomatic outcomes at 6 months after cholecystectomy, surgical removal of the gallbladder, which is the preferred treatment for gallstone disease. After cholecystectomy, a substantial number of patients report persistence of symptoms.

Methods: In this prospective follow-up study, consecutive patients (n = 172) diagnosed with symptomatic gallstone disease and indicated for elective cholecystectomy were investigated.
