- CONTEXT: Plasma fibrinogen levels may be associated with the risk of coronary heart disease (CHD) and stroke. OBJECTIVE: To assess the relationships of fibrinogen levels with risk of major vascular and with risk of nonvascular outcomes based on individual participant data. DATA SOURCES: Relevant studies were identified by computer-assisted searches, hand searches of reference lists, and personal communication with relevant investigators. STUDY SELECTION: All identified prospective studies were included with information available on baseline fibrinogen levels and details of subsequent major vascular morbidity and/or cause-specific mortality during at least 1 year of follow-up. Studies were excluded if they recruited participants on the basis of having had a previous history of cardiovascular disease; participants with known preexisting CHD or stroke were excluded. DATA EXTRACTION: Individual records were provided on each of 154,211 participants in 31 prospective studies. During 1.38 million person-years of follow-up, there were 6944 first nonfatal myocardial infarctions or stroke events and 13,210 deaths. Cause-specific mortality was generally available. Analyses involved proportional hazards modeling with adjustment for confounding by known cardiovascular risk factors and for regression dilution bias. DATA SYNTHESIS: Within each age group considered (40-59, 60-69, and > or =70 years), there was an approximately log-linear association with usual fibrinogen level for the risk of any CHD, any stroke, other vascular (eg, non-CHD, nonstroke) mortality, and nonvascular mortality. There was no evidence of a threshold within the range of usual fibrinogen level studied at any age. The age- and sex- adjusted hazard ratio per 1-g/L increase in usual fibrinogen level for CHD was 2.42 (95% confidence interval [CI], 2.24-2.60); stroke, 2.06 (95% CI, 1.83-2.33); other vascular mortality, 2.76 (95% CI, 2.28-3.35); and nonvascular mortality, 2.03 (95% CI, 1.90-2.18). The hazard ratios for CHD and stroke were reduced to about 1.8 after further adjustment for measured values of several established vascular risk factors. In a subset of 7011 participants with available C-reactive protein values, the findings for CHD were essentially unchanged following additional adjustment for C-reactive protein. The associations of fibrinogen level with CHD or stroke did not differ substantially according to sex, smoking, blood pressure, blood lipid levels, or several features of study design. CONCLUSIONS: In this large individual participant meta-analysis, moderately strong associations were found between usual plasma fibrinogen level and the risks of CHD, stroke, other vascular mortality, and nonvascular mortality in a wide range of circumstances in healthy middle-aged adults. Assessment of any causal relevance of elevated fibrinogen levels to disease requires additional research.

Journal article (peer-reviewed)abstract
- People suffering from depressive disorder are affected by one of the western world's largest medical groups of disorders in both psychiatric and general medicine. Drug treatment is usually the first-line intervention and has been shown to be an effective treatment. Other therapies, including nursing interventions that could be implemented in care, are infrequently used. It is therefore important to understand whether nurses' perceptions of depressed people could be explained from the medical model by defining the nurses' view of psychiatric inpatients. Therefore, the aim of this study was, with the clinical picture as the starting point, to investigate the nurses' view of hospitalized patients with a diagnosis of depression. In this prospective study, 155 nurses' opinion of depression among depressive inpatients was assessed using a questionnaire based on the Montgomery-Asberg Depression Rating Scale. To elucidate the relationship between the variables in the questionnaire, factor analysis rotated by the Varimax method with Kaiser's normalization was used. The factor analysis identified five factors. The number of variables was reduced from 61 to 34. Based on the factor interpretation, an initial factor structure for the depressive inpatient was defined. The identified factors were interpreted and labelled to create the nurses' fused 'picture' or meaning of the depressed inpatient as an individual who experienced feelings of annihilation, alienation, fatigue, emptiness and affliction, an individual who is disconnected from the whole of temporality.
