The prevalence of depression among 74 male and 211 female patients aged 75 years or over registered with a group general practice was assessed, using the geriatric depression scale. Test scores of 0- 10, suggesting no depressive illness, were observed in 63 (85%) men and 172 (82%) women. Mild depression (scores 11-20) was observed in 10 (14%) men and 36(17%) women and severe depression (scores 21-30) in one (1%) man and three (1%) women. No significant statistical association was found with age or sex, suggesting that elderly men and women are equally prone to depression.A general practitioner found clinical manifestations of depression in 29 of the patients (10%). The geriatric depression scale scores were compared with clinical diagnoses of depression. Those with high scores were more likely to be depressed and vice versa. Thirty two elderly patients (11%) with no clinical manifestation of depression recorded high scores on the geriatric depression scale. These patients may be described as ;psychiatric cases'. Uncertainty about the importance of early identification of these cases necessitates further screening and regular follow-up of elderly patients.

Granulocyte transfusions (GT), 0.98 X 10(9) neutrophils/kg of body weight, were performed on 7 healthy pony foals between 2 and 7 days old. The mean neutrophil count of the foals was significantly (P less than 0.05) greater than base line (4,830 +/- 1,260/microliter) 1 hour after GT (8,870 +/- 3,350/microliter) and was similar to base line by 15 to 18 hours after GT (6,550 +/- 2,310/microliter). Leukocyte concentrates (LC) used for GT were harvested from clinically normal adult horses by continuous-flow centrifugation leukapheresis (CL), 3 to 6 hours after hydrocortisone sodium succinate was administered to increase the blood neutrophil count. The mean neutrophil count of the LC used for GT was 68,050 +/- 13,990/microliter, and the mean LC volume was 377.4 +/- 79.2 ml (14.82 +/- 3.54 ml/kg). The mean time required to collect the LC used for GT was 232.1 +/- 73.4 minutes. Neutrophils from LC had significantly reduced in vitro stimulated migration to zymosan-activated serum, when compared with peripheral blood neutrophils of the donors (P less than 0.05). Neutrophil phagocytosis and bactericidal capacity were not significantly changed in LC. Mean neutrophil migration indices were not significantly different in foals after GT. Mild depression and transient diarrhea was noticed in 1 foal 30 minutes after the start of the GT. The donor of LC for this foal and 1 other donor experienced depression, piloerection, and muscle tremors during CL, indicating that complement had been activated. Problems were eliminated by the use of new disposable plastic materials for blood processing in each CL procedure.

In the open chest dog model, the response of the left ventricle exposed to acute mechanical hypertension was evaluated while the animals were receiving various concentrations of halothane, enflurane, and isoflurane. Myocardial contractility was quantified by the end-systolic pressure-length relation (ESPL). When the mean aortic pressure was increased by 40% above the control value for a given concentration of inhalation agent, the end-diastolic volume increased and thereby maintained stroke work. However, as the end-tidal concentrations of the anesthetics increased, this compensatory mechanism became progressively more ineffective as a result of myocardial depression caused by the anesthetics. No evidence could be found of an improvement in myocardial contractility as the aortic pressure was increased. Mild depression of myocardial contractility could be demonstrated for 1.1 MAC halothane, 0.6 MAC enflurane, and 1.0 MAC isoflurane. Severe depression of contractility occurred at 2.3 MAC halothane, 1.2 MAC enflurane, and 1.5 MAC isoflurane.

This study was undertaken to evaluate the chronic, long-term effect of global ischemia produced by cold potassium cardioplegia during cardiopulmonary bypass. Fifteen dogs underwent either control thoracotomy and chronic instrumentation(Group A) or cardiopulmonary bypass and 60 minutes of cold cardioplegic arrest (Group B). With the dogs conscious, hemodynamic variables and left ventricular studies were recorded weekly for 12 weeks postoperatively, both at rest and during volume overload with saline solution. At rest, the heart rate in Group B was 18% higher and stroke volume was 14% lower than Group A. With volume overload, cardiac output and maximum rate of rise of left ventricular pressure in Group B rose only from 3.7 +/- 0.6 to 7.1 +/- 0.8 liters per minute and 2,410 +/- 220 to 2,730 +/- 130 mm Hg per second, respectively, compared with 3.9 +/- 0.6 to 10.4 +/- 0.8 liters per minute and 2,740 +/- 230 to 3,890 +/- 350 mm Hg, respectively, in Group A (p less than 0.01). In Group B, the other variables reached a plateau sooner than in Group A (48 versus 110 seconds). The left ventricular function curve showed a mild decrease in functional capacity and depressed contractility. Therefore, one hour of cardioplegic cardiac arrest caused no depression of function at rest. Mild depression of left ventricular function was demonstrated up to 7 weeks postoperatively during acute volume overload.

Depression is a common disorder in the general population. However, its prevalence among patients attending various health-care facilities is less well known. There have been very few Finnish studies of this topic. The Tampere Depression Project (TADEP) dealt with the prevalence of depression and factors associated with it in individuals seen in community health centres (CHC) and in psychiatric-service (PS) patients. The diagnosis of depression was based on a standardized Present State Examination interview and a DSM-III-R assessment, carried out on 436 CHC patients and 428 PS patients. The severity of depression was assessed using the Hamilton Rating Scale of Depression. About 10% of CHC patients and 50% of PS patients suffered from clinical depression. In addition to these, some depressive symptoms were displayed by just under 10% of subjects. Similar prevalence rates were obtained by the various methods used. The 1-year prevalence rate of clinical depression was 20% for the CHC patients and almost 60% for the PS patients. Mild depression represented the largest group. In the CHC group, depression was found more often in middle-aged and widowed subjects and in patients with a lower educational level and blue-collar workers than in others. In the PS group, depression was found more often in women, the oldest subjects and the widowed than in others.

Anhedonia, a core symptom of depression, correlates with motor alterations in major depressive disorder and has been assumed to be frequent in depressed patients with Parkinson's disease (PD). In the present study, the authors assessed for the first time frequency of anhedonia in patients with idiopathic Parkinson's disease (N = 657) and the relationship of anhedonia and parkinsonian motor deficits during treatment with pramipexole. Mild depression was present in 47% of the patients and moderate to severe depression in 22%. Anhedonic individuals included 45.7% of all patients and 79.7% of depressed Parkinson's disease patients. Anhedonic Parkinson's disease patients had greater motor deficits, restrictions in activities of daily living, and depression compared to nonanhedonic patients. Frequency of anhedonia and depression was significantly reduced during treatment with pramipexole. Future studies should further investigate antianhedonic efficacy of dopamine agonists including pramipexole in depressed patients with Parkinson's disease.

Depression affects approximately 45% of all patients with Parkinson's disease, reduces quality of live independent of motor symptoms and seems to be underrated and undertreated. Pramipexole shows D(3)- versus D(2)-receptor preference at cortico-frontal dopamine receptors and neurotrophic effects which seem to relate to its antidepressant and anti-anhedonic properties in Parkinson's disease and bipolar depression found in controlled studies. In the present study, effects of pramipexole were investigated under routine clinical conditions. Anhedonia was measured in patients with Parkinson's disease (n=657) using the self-rated Snaith-Hamilton-Pleasure-Scale (SHAPS-D), depression was assessed by the observer-rated Short-Parkinson's-Evaluation Scale (SPES). Anhedonia was present in 45.7% of all patients and in 79.7% of the depressed patients with Parkinson's disease. Mild depression was present in 47%, moderate to severe depression in 22% of the patients. At the end of the study period of 9 weeks on an average, the mean dosage of pramipexole was 1.0+/-0.6 mg/d (range 0.3 to 4.2). Frequency of depression (moderate to severe: 6.8%, mild: 37.6%) and anhedonia (25.5%) as well as motor deficits were significantly reduced during treatment with pramipexole. Drop-outs due to adverse events occurred in 3.5%. Future studies should investigate specificity of anti-anhedonic and antidepressive properties of pramipexole.

An aim of a study was to establish the relationship between pain, motor complications and depression in Parkinson's disease and evaluate an effect of the 3 months therapy with the dopamine receptor agonist pramipexole (mirapex). Seventy-eight patients with idiopathic parkinsonism, aged 56-73 years, including 18 patients in stage 1-1,5 of the disease; 31 patients - in stage 2; 20 patients - in stage 3 and 9 patients - in stage 4, were studied. A stable response to the therapy was observed in 28 patients, motor complications in 50. A patient's state was assessed with widely-used scales. Thirty patients were assigned to pramipexole as an add-on therapy to L-DOPA and amantadin. Patients with dementia did not receive pramipexole. Thirty-five patients (44,8%) had pain complaints. This percentage was significantly higher (62%) in patients with motor complications. Multiple regression analysis revealed that pain scores were significantly correlated with motor complication and motor fluctuation scores. Back pain scores were correlated with an extent of posture disturbances. Mild depression and depressed mood were found in 37 patients (47,4%). VAS scores in these patients were significantly higher compared to patients without mood disturbances. The intensity of pain was correlated with depression severity. Patients treated with mirapex reported the reduction of pain by 48,2% (p<0,0001) during the "on-period". During the "off-period", the reduction of pain intensity was less (23,7%) but still significant. Depression scores were decreased to the end of the 12th week of treatment from 15,2+/-2,3 to 10,4+/-3,5 (p<0,0001).

Mild depression and anxiety were investigated in relation to measures of within-person (WP) variability and mean reaction time from psychomotor, executive function, visual search, and word recognition tasks in a continuous age range (18-85 years, M=50.33, SD=20.37) of 300 community-dwelling adults. Structural equation modeling identified a significant Age x Depression interaction in relation to visual search for measures of WP variability but not for mean reaction time. Older more depressed adults exhibited greater variability. WP variability in executive function and other cognitive constructs covaried, and the significant Age x Depression interaction with visual search was accounted for by WP variability in executive control. The findings suggest that age- and depression-related reductions in attentional resources may contribute to increased variability in visual search and that variability in executive control may be the mechanism underlying these effects.

Two hundred and fifty patients aged 25 to 50 years were examined. Arterial hypertension (AH) was diagnosed in 144 persons; its mean history was 4.35 +/- 0.5 years. Insulin-independent diabetes mellitus (IIDM) and AH were observed in 71 patients; the mean history of IIDM was 3.43 +/- 0.3 years. The patients were diagnosed as having eye diseases: mild myopia and hyperopia, first- and second-degree hypertensive angioretinopathy, and diabetic angiopathy. The purpose of the study was to assess treatment compliance for eye diseases in patients with AH and IIDM in relation to the psychological status. Treatment compliance for eye diseases in patients with AH and IIDM was found to be poor. Mild depression had no significant impact on treatment compliance for eye diseases. The patients with IIDM and diagnosed eye abnormalities without signs of depression were ascertained to take drugs to stabilize visual functions more frequently than those with eye abnormalities and AH.
