Psychosocial outcome in patients at clinical high risk of psychosis: a prospective follow-up

Purpose In patients at clinical high risk (CHR) of psychosis, transition to psychosis has been the focus of recent studies. Their broader outcome has received less attention. We studied psychosocial state and outcome in CHR patients. Methods In the European Prediction of Psychosis Study, 244 young help-seeking CHR patients were assessed with the Strauss and Carpenter Prognostic Scale (SCPS) at baseline, and 149 (61.1 %) of them were assessed for the second time at the 18-month follow-up. The followed patients were classified into poor and good outcome groups. Results Female gender, ever-married/cohabitating relationship, and good working/studying situation were associated with good baseline SCPS scores. During follow-up, patients’ SCPS scores improved significantly. Good follow-up SCPS scores were predicted by higher level of education, good working/studying status at baseline, and white ethnicity. One-third of the followed CHR patients had poor global outcome. Poor working/studying situation and lower level of education were associated with poor global outcome. Transition to psychosis was associated with baseline, but not with follow-up SCPS scores or with global outcome. Conclusion The majority of CHR patients experience good short-term recovery, but one-third have poor psychosocial outcome. Good working situation is the major indicator of good outcome, while low level of education and non-white ethnicity seem to be associated with poor outcome. Transition to psychosis has little effect on psychosocial outcome in CHR patients. In treating CHR patients, clinicians should focus their attention on a broader outcome, and not only on preventing transition to psychosis.

Psychosocial and neurocognitive performance after spontaneous nonaneurysmal subarachnoid hemorrhage related to the APOE-epsilon4 genotype: a prospective 5-year follow-up study

OBJECT: In this study, the authors prospectively evaluated long-term psychosocial and neurocognitive performance in patients suffering from nonaneurysmal, nontraumatic subarachnoid hemorrhage (SAH) and investigated the association between the APOE-epsilon4 genotype and outcome in these patients. METHODS: All patients admitted to the authors' institution between January 2001 and January 2003 with spontaneous nonaneurysmal SAH were prospectively examined (mean follow-up 59.8 months). The APOE genotype was determined in all patients by polymerase chain reaction from a blood sample. Of the 30 patients included in this study, 11 were carriers of the epsilon4 allele. RESULTS: All patients showed a good recovery and regained full independence with no persisting neurological deficits. The patients with the epsilon4 allele, however, scored significantly higher on the Beck Depression Inventory (22.1 +/- 6.3 vs 14.1 +/- 5.1). At follow-up, depression was more persistent in the group with the epsilon4 allele compared with the group that lacked the allele. This finding reached statistical significance (p < 0.05). Selective attention was impaired in all patients during the first year of follow-up, with an earlier recovery noted in the patients without the epsilon4 allele. Moreover, there was a tendency toward a linear relationship between the Beck Depression Inventory and the d2 Test of Attention. Two patients who carried the epsilon4 allele did not return to their employment even after 5 years. CONCLUSIONS: The findings in this study suggest that the APOE genotypes may be associated with the psychosocial and neurocognitive performance after spontaneous nonaneurysmal SAH, even in the absence of neurological impairment. Physicians should consider patient genotype in assessing the long-term consequences of nonaneurysmal SAH.

Inflammation as a psychophysiological biomarker in chronic psychosocial stress

The measurement of inflammation by biomarkers not only documents clinically relevant infections but also offers an important tool to pin point potentially harmful effects of chronic psychosocial stressors. This article focuses firstly on basic biology of inflammation and lists main biomarkers currently used in psycho-physiologic research. In the second part, the effects of the hypothalamic-pituitary-adrenal (HPA) axis and the autonomic nervous system as pathways modulating stress-related inflammation are discussed. Furthermore, current evidence of how chronic psychosocial stressors are related to alterations in inflammatory activity is presented. In summary, job stress, low socioeconomic status, childhood adversities as well as life events, caregiver stress, and loneliness were all shown to exert effects on immunologic activity.

Predictors of readmission and health related quality of life in patients with chronic heart failure: a comparison of different psychosocial aspects

Psychological distress is common in patients with chronic heart failure. The impact of different psychological variables on prognosis has been shown but the comparative effects of these variables remain unclear. This study examines the impact of depression, anxiety, vital exhaustion, Type D personality, and social support on prognosis in chronic heart failure patients. One hundred eleven patients (mean age 57 ± 14 years) having participated in an exercise based ambulatory cardiac rehabilitation program were enrolled in a prospective cohort study. Psychological baseline data were assessed at program entry. Mortality, readmission, and health-related quality of life were assessed at follow up (mean 2.8 ± 1.1 years). After controlling for disease severity none of the psychological variables were associated with mortality, though severe anxiety predicted readmission [HR = 3.21 (95% CI, 1.04-9.93; P = .042)]. Health-related quality of life was independently explained by vital exhaustion, anxiety and either body mass index (physical dimension) or sex (emotional dimension). As psychological variables have a strong impact on health-related quality of life they should be routinely assessed in chronic heart failure patients` treatment.

Time-referenced effects of an internal vs. external focus of attention on muscular activity and compensatory variability

The paralysis-by-analysis phenomenon, i.e., attending to the execution of one's movement impairs performance, has gathered a lot of attention over recent years (see Wulf, 2007, for a review). Explanations of this phenomenon, e.g., the hypotheses of constrained action (Wulf et al., 2001) or of step-by-step execution (Masters, 1992; Beilock et al., 2002), however, do not refer to the level of underlying mechanisms on the level of sensorimotor control. For this purpose, a “nodal-point hypothesis” is presented here with the core assumption that skilled motor behavior is internally based on sensorimotor chains of nodal points, that attending to intermediate nodal points leads to a muscular re-freezing of the motor system at exactly and exclusively these points in time, and that this re-freezing is accompanied by the disruption of compensatory processes, resulting in an overall decrease of motor performance. Two experiments, on lever sequencing and basketball free throws, respectively, are reported that successfully tested these time-referenced predictions, i.e., showing that muscular activity is selectively increased and compensatory variability selectively decreased at movement-related nodal points if these points are in the focus of attention.

Secondary prevention through cardiac rehabilitation: physical activity counselling and exercise training: key components of the position paper from the Cardiac Rehabilitation Section of the European Association of Cardiovascular Prevention and Rehabilitation

Cardiac patients after an acute event and/or with chronic heart disease deserve special attention to restore their quality of life and to maintain or improve functional capacity. They require counselling to avoid recurrence through a combination of adherence to a medication plan and adoption of a healthy lifestyle. These secondary prevention targets are included in the overall goal of cardiac rehabilitation (CR). Cardiac rehabilitation can be viewed as the clinical application of preventive care by means of a professional multi-disciplinary integrated approach for comprehensive risk reduction and global long-term care of cardiac patients. The CR approach is delivered in tandem with a flexible follow-up strategy and easy access to a specialized team. To promote implementation of cardiac prevention and rehabilitation, the CR Section of the EACPR (European Association of Cardiovascular Prevention and Rehabilitation) has recently completed a Position Paper, entitled 'Secondary prevention through cardiac rehabilitation: A condition-oriented approach'. Components of multidisciplinary CR for seven clinical presentations have been addressed. Components include patient assessment, physical activity counselling, exercise training, diet/nutritional counselling, weight control management, lipid management, blood pressure monitoring, smoking cessation, and psychosocial management. Cardiac rehabilitation services are by definition multi-factorial and comprehensive, with physical activity counselling and exercise training as central components in all rehabilitation and preventive interventions. Many of the risk factor improvements occurring in CR can be mediated through exercise training programmes. This call-for-action paper presents the key components of a CR programme: physical activity counselling and exercise training. It summarizes current evidence-based best practice for the wide range of patient presentations of interest to the general cardiology community.

Attention-deficit hyperactivity disorder (ADHD) and glial integrity: an exploration of associations of cytokines and kynurenine metabolites with symptoms and attention

In contrast to studies of depression and psychosis, the first part of this study showed no major differences in serum levels of cytokines and tryptophan metabolites between healthy children and those with attention-deficit/hyperactivity disorder of the combined type (ADHD). Yet, small decreases of potentially toxic kynurenine metabolites and increases of cytokines were evident in subgroups. Therefore we examined predictions of biochemical associations with the major symptom clusters, measures of attention and response variability.

Attention-deficit hyperactivity disorder (ADHD) and glial integrity: S100B, cytokines and kynurenine metabolism--effects of medication

Children with attention-deficit/hyperactivity disorder (ADHD) show a marked temporal variability in their display of symptoms and neuropsychological performance. This could be explained in terms of an impaired glial supply of energy to support neuronal activity.

Social cognition in attention-deficit hyperactivity disorder (ADHD)

Attention-deficit hyperactivity disorder (ADHD) is associated with a range of cognitive deficits and social cognition impairments, which might be interpreted in the context of fronto-striatal dysfunction. So far only few studies have addressed the issue of social cognition deficits in ADHD.
