Representation of hospitalized patients with pre-existing cognitive impairment in pharmaceutical delirium trials is important because these patients are at high risk for developing delirium. The aim of this systematic review is to investigate whether patients with cognitive impairment were included in studies on pharmacological prophylaxis or treatment of delirium and to explore the motivations for their exclusion (if they were excluded). ⋯ The exclusion of patients with pre-existing cognitive impairment hampers the generalizability of the results of these trials and leaves clinicians with limited evidence about the pharmacological treatment of this group of vulnerable patients who have an increased risk of side effects.

The interpersonal environment is strongly linked to sleep. However, little is known about interpersonal distress and its association with sleep. We examined the associations among interpersonal distress, objective and subjective sleep in people with and without insomnia. ⋯ Distress from interpersonal problems is associated with greater self-reported arousal and higher percent REM. Individuals with insomnia who report more distress from interpersonal problems have greater insomnia severity and cognitive presleep arousal, perhaps due to rumination. These findings extend our knowledge of the association between interpersonal stressors and sleep. Assessment and consideration of interpersonal distress could provide a novel target for insomnia treatment.

Theoretical and empirical support for the role of dysfunctional beliefs, safety behaviors, and increased sleep effort in the maintenance of insomnia has begun to accumulate. It is not yet known how these factors predict sleep disturbance and fatigue occurring in the context of anxiety and mood disorders. It was hypothesized that these three insomnia-specific cognitive-behavioral factors would be uniquely associated with insomnia and fatigue among patients with emotional disorders after adjusting for current symptoms of anxiety and depression and trait levels of neuroticism and extraversion. ⋯ Findings are consistent with cognitive behavioral models of insomnia and suggest that sleep-specific factors might be important treatment targets among patients with anxiety and depressive disorders with disturbed sleep.

Illness perceptions predict exercise capacity and psychological well-being after pulmonary rehabilitation in COPD patients.
Patients' beliefs about their disease have been associated with emotional adjustment and outcomes in several severe illnesses. The aim of the present study was to investigate whether illness perceptions before pulmonary rehabilitation influence exercise capacity and quality of life after rehabilitation in patients suffering from chronic obstructive pulmonary disease (COPD). ⋯ COPD patients' perceptions about their illness before rehabilitation influence exercise capacity and quality of life (psychological well-being) after treatment. Therefore it might be relevant to identify and change maladaptive illness perceptions in order to improve medical and psychological outcome in COPD.
