Fatigue, depression and quality of life in cancer patients: how are they related?

Abstract: In a study concerning a group of cancer patients undergoing radiotherapy three research questions were addressed. (1) Is fatigue a valid criterion for depression in these somatically ill patients? (2) What is the 'cause-and-effect' relation between fatigue and depression? (3) To what extent are fatigue and depression related to patients' quality of life. A heterogeneous sample of cancer patients (n = 250) were interviewed before treatment, 2 weeks after treatment and 9 months later. Fatigue was measured using the MFI, a self-report instrument covering five dimensions of fatigue. Depression was assessed with the non-somatic items of the CES-D. Quality of life had to be indicated on a Cantrill ladder. Fatigue and depression do not follow the same course over time. Just after radiotherapy, fatigue had either increased or remained stable, depending on the dimension under consideration. Depression, in contrast, decreased. Nine months later fatigue had decreased, whereas levels of depression remained stable. Concurrent relations between fatigue and depression were mostly moderate. There was no strong evidence for a cause-and-effect relationship between depression and fatigue. Depression showed highest concurrent relationships with quality of life, especially before treatment. Prospectively, depression and the dimension of physical fatigue were the main predictors for quality of life. Fatigue is not a valid criterion for depression in these patients. Nor is there a strong cause-and-effect relationship. Both depression and physical fatigue are relevant to patients' quality of life.

Health and disease in 85 year olds: baseline findings from the Newcastle 85+ cohort study

Abstract: Objectives The Newcastle 85+ Study aims to systematically study the clinical, biological, and psychosocial attributes of an unselected cohort of 85 year olds and to examine subsequent health trajectories as the cohort ages; health at baseline is reported. Design Cross sectional analysis of baseline data from a cohort study. Setting Newcastle upon Tyne and North Tyneside primary care trusts, United Kingdom. Participants 1042 people born in 1921 and registered with the participating general practices. Main outcome measures Detailed health assessment and review of general practice records (disease, medication, and use of general practice services); participants could decline elements of the protocol. Results Of the 1453 eligible people, 851 (58.6%) were recruited to health assessment plus record review, 188 (12.9%) to record review only, and 3 (0.2%) to health assessment only. Data from record review are reported on a maximum of 1030 and from health assessment on a maximum of 853; individual denominators differ owing to withdrawal and missing values. Of the health assessment sample (n=853), 62.1% (n=530) were women and 10.4% (n=89) were in institutional care. The most prevalent diseases were hypertension (57.5%, 592/1030) and osteoarthritis (51.8%, 534/1030). Moderate or severe cognitive impairment was present in 11.7% (96/824) of participants, severe or profound urinary incontinence in 21.3% (173/813), hearing impairment in 59.6% (505/848), and visual impairment in 37.2% (309/831). Health assessment identified participants with possible disease but without a previous diagnosis in their medical record for hypertension (25.1%, 206/821), ischaemic heart disease (12.6%, 99/788), depression (6.9%, 53/772), dementia (6.7%, 56/840), and atrial fibrillation (3.8%, 30/788). Undiagnosed diabetes mellitus and thyroid disease were rare (1%, 7/717 and 6/762, respectively). A median of 3 (interquartile range 1-8) activities of daily living were undertaken with difficulty. Overall, 77.6% (646/832) of participants rated their health compared with others of the same age as good, very good, or excellent. High contact rates in the previous year with general practitioners (93.8%, 960/1024) were recorded. Women had significantly higher disease counts (medians: women 5, men 4; P=0.033) and disability scores (medians: women 4, men 2; P=0.0006) than men, but were less likely to have attended outpatient clinics in the previous three months (women 29% (150/524), men 37% (118/320), odds ratio 0.7, 95% confidence interval 0.5 to 0.9). Conclusions This large cohort of 85 year olds showed good levels of both self rated health and functional ability despite significant levels of disease and impairment. Hypertension, ischaemic heart disease, atrial fibrillation, depression, and dementia may be underdiagnosed. Notable differences were found between the sexes: women outnumbered men and had more disease and disability.

Interleukin-6-(IL-6) plasma levels in depression and schizophrenia: comparison between the acute state and after remission.

Abstract: The concentration of cytokines such as Interleukin-6 (IL-6) has been reported to be elevated in depressed and schizophrenic patients and, in healthy persons, upon stress. Interleukin-6 plasma levels were determined in depressed (n = 12) and schizophrenic (n = 32) patients during the acute state of illness and after remission at approximately 8 weeks after admission and were compared with healthy controls (n = 12). Patients were diagnosed according to DSM-III-R by the Structured Clinical Interview (SLID). Severity of illness was assessed for depression by the Montgomery Asberg Depression Rating Scale (MADRS) and for schizophrenia by the Brief Psychiatric Rating Scale (BPRS). Interleukin-6 plasma concentrations were elevated during the acute state either of depression or of schizophrenia if compared to controls. After remission, IL-6 concentrations in depressed and in schizophrenic patients had decreased and did not differ significantly from controls. We hypothesize that the elevated IL-6 levels during the acute state of depression or schizophrenia may reflect an unspecific stress response.
