Anxiety, depression, and quality of life in caregivers of patients with cancer in late palliative phase.

BACKGROUND: Limited research has been done on mental health and health-related quality of life (QOL) of primary caregivers (PCs) to patients staying at home with advanced cancer. This study examines anxiety, depression, and QOL in PCs of patients with cancer in the late palliative phase. PATIENTS AND METHODS: The sample consisted of 49 PCs of women with breast cancer and 47 PCs of men with prostate cancer. QOL was rated with the Medical Outcome Study Short Form (SF-36), and mental health with the Hospital Anxiety and Depression Scale (HADS). The findings were compared with age-adjusted norm data (norm). RESULTS: Physical QOL was significantly higher than norm in both genders, while mental QOL was significantly lower in male PCs. The level of anxiety was significantly higher than norm in both genders. No significant difference for level of depression was found in either gender, while caseness of HADS-defined depression was significantly more prevalent in female PCs compared with norm. CONCLUSION: PCs of both genders had significantly more anxiety than norm samples. Health care personnel in contact with PCs should consider screening them for mental symptoms and QOL and, if necessary, recommend further evaluation by their doctors.

Are there more than cross-sectional relationships of social support and support networks with functional limitations and psychological distress in early rheumatoid arthritis? the European Research on Incapacitating Diseases and Social Support Longitudinal Study.

OBJECTIVE: To investigate whether greater social support and support network are cross-sectionally associated with less functional limitations and psychological distress in patients with early rheumatoid arthritis (RA); whether this association is constant over time; and whether increases in social support or support network are associated with less functional limitations and psychological distress. METHODS: Subjects were from the European Research on Incapacitating Diseases and Social Support cohort and had early RA. Social support, support network, functional limitations (Health Assessment Questionnaire), and psychological distress (General Health Questionnaire) were assessed annually. Variance and covariance analyses with repeated measures were performed. RESULTS: A total of 542 subjects were assessed for 3 years. On average, patients with a greater amount of specific social support or a stronger specific support network experienced less functional limitation and less psychological distress. Changes in a given subject's functional limitations and psychological distress did not depend on his or her baseline social support or support network. Neither social support nor support network change over time. CONCLUSION: There may be a cross-sectional link between specific social support or support network and functional limitations and psychological distress, but no longitudinal association could be evidenced.

Fatigue and its association with sociodemographic variables among multiple sclerosis patients.

OBJECTIVE: To explore the relationship between fatigue, sociodemographic and clinical variables in a population of patients with multiple sclerosis (MS). RATIONALE: There is a need to identify empirical relationships with possible antecedents of fatigue among patients with MS. METHODS: A mailed questionnaire designed to survey sociodemographic variables and the Fatigue Severity Scale (FSS) was mailed to 502 individuals from the population of patients with definite MS in the city of Oslo. A total of 368 (73%) responded. Clinical data were collected from the Oslo City MS-Registry. RESULTS: The prevalence of fatigue in this population was 60.1%. The FSS score showed a negative correlation with education (r = -0.15, P < 0.01) and a positive correlation with age (r = 0.20, P < 0.001) and time since disease onset (r = 0.11, P < 0.05). When controlled for gender, level of education and time since disease onset, the data showed a positive relationship between fatigue and age (P < 0.001) among patients with primary progressive (PP) disease. This relationship between age and fatigue was not found among patients with relapsing-remitting/secondary progressive (RR/SP) disease. CONCLUSION: The negative relationship between level of formal education (FE) and fatigue among individuals with RR/SP disease suggests that behavioral factors may be among the antecedents of fatigue in this patient group. In contrast to normative data from the general population, our findings revealed no differences in fatigue related to gender Thus, this study supports the hypothesis that there are disease-specific antecedents of fatigue among patients with MS.

Quality of life in patients with inflammatory bowel disease: translation, data quality, scaling assumptions, validity, reliability and sensitivity to change of the Norwegian version of IBDQ.

BACKGROUND: The use of quality of life (QoL) questionnaires in clinical medicine must be based on instruments that are reliable and valid. The aim of this study was to describe the translation of the Inflammatory Bowel Disease Questionnaire (IBDQ) into Norwegian, its scaling assumptions and the psychometric properties of the translated questionnaire. METHOD: All patients included were recruited from an ongoing epidemiological study started in 1990 (the IBSEN trial), based on the registration of undiagnosed cases of Crohn disease (CD) or ulcerative colitis (UC) in subjects permanently residing in the study area the year before registration. At the 5-year follow-up visit in the hospital, all patients between 18 and 75 years of age were invited to participate in this QoL study, and those willing were interviewed and asked to complete the two QoL questionnaires, IBDQ and SF-36, on two different occasions separated by 6 months. The IBDQ was tested for validity, reliability and responsiveness. RESULTS: In total, 497 patients (93%) completed the IBDQ questionnaire at visit 1, and 493 (92%) completed SF-36. The mean age was 43.3 years, 48% were female. We found that the Norwegian version of the IBDQ (N-IBDQ) consists of five underlying dimensions in contrast to the four dimensions previously reported. Psychometric testing of the N-IBDQ indicates that the questionnaire is valid, reliable, has a high degree of responsiveness and that the results are comparable to those reported from other groups, even though our findings are based on a different factorial structure than the original McMaster version. CONCLUSION: The N-IBDQ consists of five different dimensions in contrast to the four dimensions previously reported. Good item internal consistency, validity, reliability and responsiveness were demonstrated.

Quality of life profiles in the first years of rheumatoid arthritis: results from the EURIDISS longitudinal study.

OBJECTIVE: The aim of this study was to examine the quality of life (QoL) profiles of patients with early rheumatoid arthritis (RA) and to relate these to disease and impairment variables as indicated, respectively, by erythrocyte sedimentation rate (ESR) and by tender joint count (Ritchie Articular Index), fatigue, and pain. METHODS: The present study uses part of the European Research on Incapacitating Disease and Social Support data of 573 patients with recently diagnosed RA (268 from the Netherlands, 216 from Norway, and 89 from France). A series of clinical and psychosocial data were collected on 4 (the Netherlands, France) and 3 (Norway) occasions, with 1-year intervals separating the waves of data collection. RESULTS: Of the disease activity (ESR) and impairment variables (tender joint count, fatigue, pain), fatigue was identified as the consequence of disease that differentiated best on a series of QoL aspects such as disability, psychological well-being, social support, and "overall evaluation of health." Next came pain and tender joint count, and ESR showed by far the least differentiating ability. A principal-component analysis on the QoL measures used in this study yielded one general factor measuring "overall QoL." After rotation, two separate factors were encountered, one referring to the physical domain and the other to the psychological and social domains of QoL. Again, the QoL of RA patients experiencing much fatigue appeared to decline the most. CONCLUSIONS: Because of the highly variable nature of RA, impairments, activities of daily living (ADL) and instrumental ADL restrictions, and psychosocial distress can vary erratically. In particular, "fatigue" as measured over a period of 2 to 3 years distinguished best among RA patients as shown by their QoL profiles. Although the physical domain was most affected, the significant effect of RA on the psychosocial domain should not be underestimated.

Mitochondrial control region structure and single site heteroplasmy in the razorbill (Alca torda; Aves).

The primary structure of the Alca torda mitochondrial control region was determined and conserved structural features were identified based on sequence comparisons to other bird species. In a population survey using control region analysis, five individuals were found to possess heteroplasmic point mutations at the variable 5' end of the control region. The pattern of variable nucleotide positions among individuals was compared to the distribution of heteroplasmic sites and the heteroplasmic condition was further characterised by a cloning procedure applied to two individuals which harboured one and two heteroplasmic point mutations, respectively. These results are in support of recent evidence that single site heteroplasmy may be more common than previously thought.

Genetic diversity and population history of two related seabird species based on mitochondrial DNA control region sequences.

Geographical variation in two related seabird species, the razorbill (Alca torda) and common guillemot (Uria aalge), was investigated using sequence analysis of mitochondrial DNA (mtDNA) control regions. We determined the nucleotide sequence of the variable 5' segment of the control region in razorbills and common guillemots from breeding colonies across the Atlantic Ocean. The ecology and life history characteristics of razorbill and common guillemot are in many respects similar. They are both considered highly philopatric and have largely overlapping distributions in temperate and subarctic regions of the North Atlantic, yet the species were found to differ widely in the extent and spatial distribution of mtDNA variation. Moreover, the differences in genetic differentiation and diversity were in the opposite direction to that expected from a consideration of traditional classifications and current population sizes. Indices of genetic diversity were highest in razorbill and varied among colonies, as did genotype frequencies, suggestive of restrictions to gene flow. The distribution of genetic variation suggests that razorbills originated from a refugial population in the south-western Atlantic Ocean through sequential founder events and subsequent expansion in the east and north. In common guillemots, genetic diversity was low and there was a lack of geographical structure, consistent with a recent population bottleneck, expansion and gene flow. We suggest that the reduced level of genetic diversity and differentiation in the common guillemot is caused by an inherent propensity for repeated population bottlenecks and concomitantly unstable population structure related to their specialized feeding ecology.

Speciation, introgressive hybridization and nonlinear rate of molecular evolution in flycatchers.

Evolutionary history of Muscicapidae flycatchers is inferred from nuclear and mitochondrial DNA (mtDNA) sequence comparisons and population genetic analysis of nuclear and mtDNA markers. Phylogenetic reconstruction based on sequences from the two genomes yielded similar trees with respect to the order at which the species split off. However, the genetic distances fitted a nonlinear, polynomial model reflecting diminishing divergence rate of the mtDNA sequences compared to the nuclear DNA sequences. This could be explained by Haldane's rule because genetic isolation might evolve more rapidly on the mitochondrial rather than the nuclear genome in birds. This is because hybrid sterility of the heterogametic sex (females) would predate that of the homogametic sex (males), leading to sex biased introgression of nuclear genes. Analyses of present hybrid zones of pied (Ficedula hypoleuca) and collared flycatchers (F. albicollis) may indicate a slight sexual bias in rate of introgression, but the introgression rates were too low to allow proper statistical analyses. It is suggested, however, that the observed deviation from linearity can be explained by a more rapid mutational saturation of the mtDNA sequences than of the nuclear DNA sequences, as supported by analyses of third codon position transversions at two protein coding mtDNA genes. A phylogeographic scenario for the black and white flycatcher species is suggested based on interpretation of the genetic data obtained. Four species appear to have diverged from a common ancestor relatively simultaneously during the Pleistocene. After the last glaciation period, pied and collared flycatchers expanded their breeding ranges and eventually came into secondary contact in Central and Eastern Europe and on the Baltic Isles.

[Need of better knowledge of genetic tests among Norwegian physicians].

BACKGROUND: New predictive genetic tests are introduced in clinical work, and this means new tasks for the physician. MATERIAL AND METHODS: Every sixth member of the Norwegian Medical Association practising as a general practitioner, neurologist or psychiatrist (N = 732), were asked to answer a mailed, anonymous questionnaire about their attitudes to the new tasks. RESULTS: We obtained 451 (62%) answers. There were no significant differences between the various groups in the profession. So far, 54% had no patient in their practice who had taken a predictive genetic test. About two-thirds answered that the geneticist should inform about what is known about the consequences after a test result has been given. The general practitioner wants to do the follow-up. 97% of physicians think that the test result could lead to increased distress in various ways for the tested person or his/her family. Half of the physicians would advise taking a prenatal test if one of the parents had a known risk of an inherited disease and the foetus was at risk. Only 22% are in favour of abortion if the foetus has the gene in question. INTERPRETATION: The physicians (93%) do not think they have sufficient knowledge about predictive genetic tests to handle the information procedure on their own. They want courses in medical genetics, concise and relevant information from geneticists, and the possibility of consulting with specialists.

Discrepancies in population differentiation at microsatellites, mitochondrial DNA and plumage colour in the pied flycatcher--inferring evolutionary processes.

Genetic differentiation between three populations of the pied flycatcher Ficedula hypoleuca (Norway, Czech Republic and Spain, respectively) was investigated at microsatellite loci and mitochondrial DNA (mtDNA) sequences and compared with the pattern of differentiation of male plumage colour. The Czech population lives sympatrically with the closely related collared flycatcher (F. albicollis) whereas the other two are allopatric. Allopatric populations are on average more conspicuously coloured than sympatric ones, a pattern that has been explained by sexual selection for conspicuous colour in allopatry and a character displacement on breeding plumage colour in sympatry that reduces the rate of hybridization with the collared flycatcher. The Czech population was genetically indistinguishable from the Norwegian population at microsatellite loci and mtDNA sequences. Recent isolation and/or gene flow may explain the lack of genetic differentiation. Accordingly, different selection on plumage colour in the two populations is either sufficiently strong so that gene flow has little impact on the pattern of colour variation, or differentiation of plumage colour occurred so recently that the (presumably) neutral, fast evolving markers employed here are unable to reflect the differentiation. Genetically, the Spanish population was significantly differentiated from the other populations, but the divergence was much more pronounced at mtDNA compared to microsatellites. This may reflect increased rate of differentiation by genetic drift at the mitochondrial, compared with the nuclear genome, caused by the smaller effective population size of the former genome. In accordance with this interpretation, a genetic pattern consistent with effects of small population size in the Spanish population (genetic drift and inbreeding) were also apparent at the microsatellites, namely reduced allelic diversity and heterozygous deficiency.

Drug consumption in the first years of rheumatoid arthritis in France, The Netherlands, and Norway. A longitudinal study in the early nineties.

OBJECTIVE: To analyse drug consumption in the first years of rheumatoid arthritis (RA) in France, the Netherlands, and Norway, in a longitudinal study between 1991 and 1993. PATIENTS AND METHODS: The EURIDISS cohort followed up over three years included 695 RA subjects with less than 5 years disease duration. Clinical and biological parameters, drug consumption according to ATC classification, and use of local treatment were recorded. RESULTS: In the Netherlands consumption of second-line treatment occurred early on, and remained constant over time. In France, it was consumed by half of the subjects and decreased during follow-up (p<0.001). In Norway, 50% of the subjects were on second-line treatment at the outset. NSAIDs rather than corticoids were the most widely consumed. Patients underwent frequently local treatments with decrease frequency of infiltrations over time (p<0.001). CONCLUSION: Second-line treatments were used in the first years of disease development, following varying sequences in the different countries.

Social network size of female patients with rheumatoid arthritis compared to healthy controls.

UNLABELLED: To estimate how rheumatoid arthritis (RA), the disease duration, and level of physical disability, influence the total size of patients' social network and the size of different subsets. Two hundred sixty four female patients (mean age 57 yrs) with RA of more than 6 yrs duration (mean 20 yrs) were compared to 61 healthy controls matched for sex, age, and residential area. Network size was measured by Social Network Delineation Questionnaire (SNDQ), physical disability by Health Assessment Questionnaire (HAQ). RA patients had a significantly smaller total network compared to the healthy controls (RA: 15.8 persons; CONTROLS: 18.1), mostly due to a significant difference in the subset of important others in favour of the controls (RA: 1.1; CONTROLS: 2.3). There were no significant differences regarding the network size of family, friends, and neighbours. The same results remained after statistical control for sociodemographic variables. Neither disease duration nor physical disability had any significant association with network size. The interaction analysis did, however, show that non-working patients with long disease duration (> 15 yrs) had fewer important others than occupationally active patients. Furthermore, a high degree of physical disability was related to a smaller number of friends for patients > 57 yrs than for equally disabled patients below this age. Most patients with RA seem to maintain contact with the family network-members, despite the challenges connected with chronic disease.

The course of rheumatoid arthritis and predictors of psychological, physical and radiographic outcome after 5 years of follow-up.

OBJECTIVE: : To examine the course of RA over 5 yr and identify predictors of psychological, physical and radiographic outcome. PATIENTS AND METHODS: Out of 238 patients with rheumatoid arthritis of no more than 4 (mean 2.2) yr duration, 182 (76%) completed a clinical examination with follow-up at 1, 2, and 5 yr. The course of the disease was assessed by measures of psychological and physical health status, disease process and radiographic damage. RESULTS: : Over 5 yr we observed at a group level a stable disease course for measures of disease process, psychological and physical health status. Radiographic damage progressed. Health status and radiographic damage after 5 yr were predicted by the baseline measures for the respective outcome. Physical function was also predicted by age and by psychological status when the physical dimension of the Arthritis Impact Measurement Scales was chosen as outcome variable. Erythrocyte sedimentation rate and presence of rheumatoid factor predicted radiographic progression. CONCLUSIONS: : The 5 yr course of RA was characterized by preserved health status measures and clinically preserved disease process measures, whereas joint damage progressed steadily. Outcomes after 5 yr can be predicted partly by certain measures at baseline.

Inventory of interpersonal problems: a three-dimensional balanced and scalable 48-item version.

Interpersonal relating has been a focus of attention in psychiatry for decades. To address this domain, a self-rating scale, the Inventory of Interpersonal Problems (IIP; Horowitz, Rosenberg, Baer, Ureño, & Villaseñor, 1988), was developed. Analysis of the psychometric properties of IIP presented in this article was performed by principal component analysis (PCA) for the purpose of obtaining subscales with a balanced, bipolar dimensionality. The model was validated by the resulting dimensions' ability to discriminate among different categories of personality disorders (PDs). The problem of a General Complaint factor affecting PCAs of questionnaires such as the IIP is discussed thoroughly, and ways of avoiding the problem are outlined. We present a three-dimensional structure of the IIP with both theoretically appealing and statistically robust dimensions of Assertiveness, Sociability, and Interpersonal Sensitivity based on 48 (out of 127) items. Balanced, additive indexes using the subset of 48 items appeared psychometrically sound by showing much lower correlations internally and less confounding from the General Complaint factor than extant indexes derived from the IIP. External validity seemed to be bolstered by all subscales' discriminating significantly between different PDs versus no PDs, on both cluster and single diagnosis levels. Our analysis seemed to substantiate the reliability (scalability) of three dimensions of the IIP tapping different areas of the interpersonal relational field.

Compliance with drug therapy in rheumatoid arthritis. A longitudinal European study.

OBJECTIVE: To delineate compliance with drug therapy in rheumatoid arthritis patients, determine specific characteristics of compliant and noncompliant patients, and look for changes in compliance over time. PATIENTS AND METHODS: A prospective European cohort study (EURIDISS) recruited 556 patients in four countries over three years. Compliance with drug dosages and dosing times was evaluated yearly using a questionnaire. RESULTS: Of the 556 patients, 429 (77.2%) were on drug therapy at all three evaluation time points. Use of steroids, nonsteroidal anti-inflammatory drugs, and second-line drugs varied significantly across countries. The compliance behavior was stable over time in 59.5% of them (35.7% of patients were consistently compliant and 23.8% consistently noncompliant); it was independent of disease duration and from the clinical features of the disease. Older patients and women were more likely to be compliant (odds ratios, 2.5 and 2, respectively). CONCLUSION: Compliance with drug therapy can be measured using two simple questions. Compliance is more closely dependent on individual behavior than on responses to specific features of rheumatoid arthritis.
