The objectives of this prospective cohort study were to 1) determine the prevalence of depressed mood, 2) identify the characteristics associated with it, and 3) evaluate the recognition rate of depressed mood by clinicians. The study population was a cohort of 401 elderly patients, aged 75 years and older, admitted to the internal medicine service of a tertiary care academic medical center in Western Switzerland over six months. We excluded patients with severe cognitive impairment, terminal disease or those living in a nursing home. Data on demographics, medical, physical, social and mental status were collected upon admission. Presence of depressed mood was defined as a score > or = 6 on the Geriatric Depression Scale (GDS), short form (15-item). An independent reviewer performed a discharge summary abstraction to assess recognition rate. Subjects' mean age was 82.4 years, 60.9% were women. Overall, 90 patients (22.40%) had an abnormal GDS score (> or =6). Compared to those without a depressed mood, these subjects were (all p<0.05) older (83.5 vs 82.0 years), more frequently living alone (66.7 vs 55.0%), dependent in both basic activities of daily living (BADL) and instrumental ADL (48.9 vs 36.0%, and 91.1 vs 84.9%, respectively), and cognitively impaired (47.8 vs 27.7% with MMSE score<24). In addition, they had more comorbidities (Charlson index 1.6 vs 1.2). In multivariate analysis, an independent association remains for subjects living alone (OR 1.8, 95%CI 1.1-3.0), with cognitive impairment (OR 1.9, 95%CI 1.1-3.2), and comorbidities (OR 1.3 per point, 95%CI 1.1-1.5). Detection rate during the index hospitalization was only 16.7% (15/90). In conclusion, depressed mood was frequent but rarely detected in this population. These findings emphasize the need to improve screening efforts, and to develop additional strategies such as using a pre-screening question to enhance clinical recognition.

The present article reviews the studies so far published on the psychopharmacological effects mediated by tachykinin NK-3 receptors in laboratory animals. Central administration of NK-3 receptor agonists has been reported to attenuate alcohol intake in alcohol-preferring rats and to evoke conditioned place preference. These findings suggest that NK-3 receptors may affect reward processes to drugs of abuse. Anxiolytic-like and antidepressant-like effects have been previously reported for NK-1 receptor antagonists, and anxiolytic-like effects for NK-2 receptor antagonists. More recently, it has been shown that NK-3 receptor agonists have anxiolytic-like and antidepressant-like effects in mice and rats, while an NK-3 receptor antagonist was reported to be anxiogenic in mice. These findings indicate that different TK receptor subtypes may be involved in anxiolytic-like and antidepressant-like effects in laboratory animals and raise interest for the possible role of NK-3 receptors in the control of anxiety and depression in man.

A brief overview of recent developments in the substance P field is provided, in addition to a historical introduction. It is emphasized that there are multiple tachykinins and tachykinin receptors and that there are examples of coexistence of several tachykinin peptides and of several tachykinin receptors in single cells, and there is evidence for tachykininergic cotransmission. The distribution and functional significance of tachykinins in the gastrointestinal tract and in sensory neurones, and interactions with other peptides and transmitters, are reviewed. The recent production of knock-out mice for either substance P or the NK1 receptor is discussed, as well as the exciting concept of substance P receptor internalization. Finally, the development of specific substance P antagonists is summarized, and possible clinical implications discussed, and, in particular, a recent study which reports that a substance P antagonist shows clinical efficacy in depression.

Our objective was to identify patient characteristics associated with inappropriate hospital days in a cohort of elderly medical inpatients. This prospective cohort study included a total of 196 patients aged 75 years and older, who were consecutively admitted over eight months to the internal medicine service of a regional, non-academic public hospital located in a rural area of Western Switzerland. Patients with severe cognitive impairment, terminal disease, or previously living in a nursing home were excluded. Data on demographics, medical, physical, social and mental status were collected at admission. A blinded hospitalization review was performed concurrently using a modified version of the Appropriateness Evaluation Protocol (AEP). Subjects' mean age was 82.4 years; 63.3% were women. Median length of stay was 8 days. Overall, 68 patients (34.7%) had at least one inappropriate day during their stay, including 18 patients (9.2%) whose hospital admission and entire stay were considered inappropriate. Most inappropriate days were due to discharge delays (87.10%), primarily to nursing homes (59.30%). Univariate analysis showed that subjects with inappropriate days were more likely to be living alone (69.1 vs 48.4%, p=0.006), and receiving formal in-home help (48.5 vs 32.8%, p=0.031). In addition, they were more impaired in basic and instrumental activities of daily living (BADLs, and IADLs, p<0.001 and p=0.015, respectively), and more frequently had a depressed mood [29.4 vs 10.9%, p=0.001 with a score > 6 at the Geriatric Depression Scale (GDS), short form]. Using multivariate analysis, independent associations remained for patients living alone (OR 2.6, 95%CI 1.2-5.8, p=0.016), those with a depressed mood (OR 2.8, 95%CI 1.1-7.3, p=0.032), with BADL dependencies (OR 1.5, 95%CI 1.2-1.8, p=0.001), and IADL dependencies (OR 1.3, 95%CI 1.0-1.6, p=0.032). Cardiovascular (OR 0.2, 95%CI 0.1-0.7, p=0.008) and pulmonary admission diagnoses (OR 0.1, 95%CI 0.0-0.7, p=0.022) were inversely associated with inappropriate hospital days. In conclusion, patients living alone, functionally impaired and showing depressive symptoms were at increased risk for inappropriate hospital days. These characteristics might permit better targeting for early discharge planning in these at-risk subjects, and contribute to avoiding premature discharge of other vulnerable elderly patients. Whether these interventions for at-risk patients will also result in prevention of hospitalization hazards, such as deconditioning and related functional decline, will require further study.

To test the psychometric properties of the Chinese (Taiwanese) version of the short form 36 health survey (SF-36), 1,439 women, aged 40-54 years and living in Kinmen (a Taiwanese island reflecting a predominantly rural community) were recruited to participate in this survey. The rate of unavailable data points for the 36 tested items remained consistently low, and item-discriminate validity was high (95%) for all subscales. Cronbach's alpha coefficient remained above the 0.70 threshold criterion for all scales except for social functioning and bodily pain. Principal components analysis supported the two major dimensions of health, physical and mental, in the internal structure of the SF-36 scales, although the dimensions did not match the hypothesized association very well. Poorer health profiles were associated with physical and mental conditions. The mental health subscores in the SF-36 test correlated highly with the associated hospital anxiety and depression score (Spearman rank correlation coefficient = -0.62). In conclusion, the reliability and validity tests performed on the data collected support the cross-cultural application of the Chinese (Taiwanese) version of the SF-36 test.

A variety of medications have been reported to cause depression as a side effect. This study evaluated cross-sectional associations between a variety of medications and a syndrome resembling major depression. A sample of 2,542 subjects were selected using the Mitofsky-Waksberg random digit dialing (RDD) procedure. Major depression was evaluated using a short form version of the Composite International Diagnostic Interview (CIDI). Current medication use was recorded during the same telephone interview. Statistical methods accounting for clustering and unequal selection probabilities were employed. Most medications were not associated with major depression: these included beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, lipid-lowering agents, digoxin, and diuretics. Calcium channel blockers were significantly associated with major depression, but only in a subset of young subjects, and these tended to be seriously ill individuals taking multiple medications. Opiate analgesics were associated with major depression, but only in male subjects. Corticosteroids were significantly associated with major depression in a logistic regression model that adjusted for age and gender. The cross-sectional nature of this study precludes causal inference about the observed associations. With the exception of the association of major depression with corticosteroid use, convincing associations with other medications were not observed. It is possible that medication-induced depressive episodes lead to changes in exposure status (such as discontinuation of the offending medications) such that the associations are not apparent in cross-sectional data. If this interpretation is correct, these data suggest that the problem of medication-induced depression is being managed effectively at the clinical level and is not a substantial public health problem.

This article provides a brief overview of the history of substance P from its discovery in the 1930s to the present day. The development of substance P receptor agonists and antagonists, and more recently the employment of transgenic mice, provide a framework to explore the functional role of substance P. Chronic inflammation and pain are associated with a number of diseases, and it has been proposed that substance P, released from primary afferent nerve endings play a role in these conditions. Recent developments with substance P antagonists have demonstrated the importance of substance P in several models of disease that span from asthma to chronic bronchitis; from cystitis, inflammatory bowel disease to migraine; emesis, depression, pain and seizures. Advancements in the knowledge of the role of substance P, its agonists and antagonists could provide clinical solutions for a variety of chronic inflammatory conditions.

There is considerable evidence for a unitary and dimensional view of the genetic vulnerability to symptoms of anxiety and depression. The GENESiS (Genetic Environmental-Nature of Emotional States in Siblings) Study aims to use a multivariate approach to detect genetic loci that contribute to individual differences in this vulnerability dimension. The study used the UK General Practice Research Framework to generate a community-based sample of siblings. Questionnaire measures of anxiety/depression included the short form of the neuroticism scale from the revised Eysenck Personality Questionnaire (EPQ-N), the General Health Questionnaire (GHQ-12), and the anxious arousal and high positive affect subscales from the Mood and Anxiety Symptoms Questionnaire (MASQ-AA and MASQ-HPA). Genetic model-fitting of 2658 unselected sibships provided evidence for a single common genetic (familial) factor that accounted for a substantial proportion of the genetic variances and covariances of these four measures. Using the parameter estimates of this model, we constructed a composite index of this common genetic factor. This index, which has a sib correlation of 0.22, will be used as a quantitative phenotype in the molecular genetic phase of GENESiS.

In order to examine the relationship between depressive symptoms and the lipid metabolism in the elderly with hypertension, we recruited 311 outpatients aged 65 or older with hypertension and defined depression as patients with 6 or more symptoms on Geriatric Depression Scale short form. We further classified depressed patients into three groups: mild depressed with 6-7 symptoms, moderate depressed with 8-10 symptoms and severe depressed with 11 or more symptoms. Serum total cholesterol, serum HDL cholesterol and serum LDL cholesterol levels were significantly higher in female depressed patients than those in nondepressed patients (TC, 194.6 +/- 30.1 vs 208.0 +/- 32.8 p < 0.01; HDL, 67.3 +/- 19.3 vs 72.3 +/- 16.2 p < 0.01; LDL, 107.6 +/- 26.5 vs 116.0 +/- 29.1 p < 0.05). In male patients, serum lipids were not significantly associated with depressive symptoms but depressed patients were significantly older than nondepressed patients (75.3 +/- 6.2 vs 78.0 +/- 5.9 p < 0.05). Concerning the analysis of the severity of depression, serum total cholesterol and serum LDL cholesterol levels were significantly higher in mildly depressed patients than nondepressed patients in females and the same tendency was seen in male patients. No linear associations were shown between the severity of depression and serum lipids. We concluded that hyperlipidemia may be associated with depressive symptoms in elder patients with hypertension and that it might be related the severity of depression. We need to further investigate the relationship between depression and lipid metabolism in larger population samples.

The effects of insulin therapy on patient well-being, treatment satisfaction and mood, and on carer strain were studied in 30 elderly Type 2 diabetic patients (age 73 +/- 7 (SD) yr) in poor glycaemic control on tablet therapy. A comparison group of ten poorly controlled patients who remained on oral agents was also studied. After 4 weeks of insulin treatment, there were significant improvements in mental health, role-emotional, role-physical (all P<0.05) and vitality (P<0.01) domains of the short form health survey (SF-36), and also in the diabetes treatment and satisfaction questionnaire (DTSQ) and geriatric depression scale (both P<0.01) compared to baseline. After 12 weeks, the improvements in mental health, social functioning and vitality (P<0.01 for all domains), and in the DTSQ were sustained. Carer strain was lower at 4 weeks. No changes in outcomes were seen in the comparison group. In selected elderly Type 2 diabetic patients, insulin treatment is associated with significant improvements in well-being, treatment satisfaction and mood, even without significant improvements in glycaemic control and without increase in carer strain. The SF-36 and DTSQ are sensitive to the benefits of the changes in the treatment for these patients.
