    Notes: Background:  Limited information is available about anxiety, depression and psychotropic medication use in patients referred for gastrointestinal endoscopy.Aim:  To determine anxiety and depression and its association with endoscopic findings in a representative sample of patients with persistent gastrointestinal symptoms prior to endoscopy.Methods:  Patients referred to the hospital for endoscopy between February 2002 and February 2004 were asked to score anxiety and depression on the Hospital Anxiety and Depression Scale 2 weeks prior to endoscopy. Information about endoscopic diagnoses was obtained from medical files.Results:  A total of 1298 subjects was studied (600 upper gastrointestinal endoscopies and 698 lower gastrointestinal endoscopies). Patients referred for upper gastrointestinal endoscopy used most psychotropic agents (24%; odds ratio = 3.1; 95% confidence interval = 2.3–4.2), especially patients with an organic abnormality when compared with patients without an organic abnormality (42% versus 8%; odds ratio = 8.6; 95% confidence interval = 5.4–14.0). Patients with colonic polyps were more anxious (odds ratio = 1.7; 95% confidence interval = 1.0–2.9) and depressed (odds ratio = 1.8; 95% confidence interval = 1.1–3.1) than other patients referred for lower gastrointestinal endoscopy.Conclusions:  There is no difference in anxiety nor depression between patients with and without organic abnormalities at endoscopy. Patients with colonic polyps are more anxious and depressed than other patients referred for lower gastrointestinal endoscopy. Psychotropic medication use is highest among patients with an organic abnormality in the proximal gastrointestinal tract.

    Health-related quality of life of patients with gastrointestinal symptoms (2004)

    Notes: Background : Little is known about the variation in health-related quality of life among patients with different presentations of gastrointestinal symptoms.Aim : To study the association between health-related quality of life and presentations of gastrointestinal symptoms.Methods : Health-related quality of life and demographic information was obtained from 873 patients referred to the hospital for endoscopy, using a questionnaire.Results : A total of 436 patients (50%) reported predominantly upper gastrointestinal symptoms, 344 (39%) predominantly lower symptoms, and 93 (11%) patients reported both upper and lower symptoms. Patients with mild, moderate and severe symptoms, reported mean scores on a 100-point visual analogue scale (95% CI) of 90 (79–100), 75 (64–86) and 64 (53–76), respectively (P 〈 0.001). Mean visual analogue scale scores (95% CI) almost linearly declined from 81 (77–85) to 49 (46–52) for those with one to those with more than eight symptoms. Patients who reported upper gastrointestinal symptoms and in particular epigastric pain, bloating and vomiting had significantly impaired health status in comparison to patients without these symptoms (P 〈 0.05).Conclusions : Severity of gastrointestinal symptoms is the most important factor in affecting health status, followed by the numbers and type of gastrointestinal symptoms.

    Kinetics of atrial natriuretic peptide in young and elderly subjects (1992)

    Notes: Summary To study the influence of age on the kinetics of atrial natriuretic peptide (ANP) in man, human (99–126) ANP 2.0 μg·min−1 was infused IV for 60 min in 8 healthy young (18 to 25 y) and 9 healthy elderly (71 to 84 y) subjects. Both baseline ANP values and the levels at the end of infusion were higher in the elderly subjects. The mean residence time of ANP in the two age groups was not significantly different, whereas total body clearance (CL) was markedly diminished in the elderly as compared to the young subjects (mean±SD 3.1±1.0 l·min−1 and 6.2±4.1 l·min−1, respectively). The apparent volume of distribution at steady state was lower in the elderly than in the young, but the difference was not significant (mean±SD 44±19 and 103±111, respectively. The decrease in CL largely explained the higher ANP levels found in the elderly subjects. The MRT and the plasma half-life of the terminal phase did not differ between the two groups. In the elderly but not in the young subjects the calculated endogenous creatinine clearance was closely correlated with the CL (r=0.90, P〈0.001), thereby emphasizing the importance of the kidney in the metabolic clearance of ANP in the elderly.
