Sleep disturbance in patients attending specialized chronic pain clinics in Denmark: a longitudinal study examining the relationship between sleep and pain outcomes.

Objectives: Sleep disturbances are highly prevalent in patients with chronic pain. However, the majority of studies to date examining sleep disturbances in patients with chronic pain have been population-based cross-sectional studies. The aims of this study were to 1) examine the frequency of sleep disturbances in patients referred to two interdisciplinary chronic pain clinics in Denmark, 2) explore associations between sleep disturbances and pain intensity, disability and quality of life at baseline and follow-up, and 3) explore whether changes in sleep quality mediated the relationships between pain outcomes at baseline and pain outcomes at follow-up.

The Two Faces of Janus: Why Thyrotropin as a Cardiovascular Risk Factor May Be an Ambiguous Target.

Elevated concentrations of free thyroid hormones are established cardiovascular risk factors, but the association of thyrotropin (TSH) levels to hard endpoints is less clear. This may, at least in part, ensue from the fact that TSH secretion depends not only on the supply with thyroid hormones but on multiple confounders including genetic traits, medication and allostatic load. Especially psychosocial stress is a still underappreciated factor that is able to adjust the set point of thyroid function.

Validity of the Mini-Mental State Examination-2 in Diagnosing Mild Cognitive Impairment and Dementia in Patients Visiting an Outpatient Clinic in the Netherlands.

This study examined the utility of the recently published MMSE-2:SV in detecting cognitive impairment. We used receiver operating characteristics to test the discriminative power of the MMSE-2:SV for distinguishing between older adults without mild cognitive impairment (MCI) or dementia (n=67) and patients with MCI (n=76) or dementia (n=79). The results show that the MMSE-2:SV had excellent discriminative ability in distinguishing older controls from patients with dementia, with cut-off scores of 26 and 27 (max=30) yielding appropriate sensitivity (0.

[Applicability and validity of the Dutch version of the Montreal Cognitive Assessment (moCA-d) in diagnosing MCI].

Objective: The MoCA is a new screening test to detect Mild Cognitive Impairment (MCI). Purpose of this study is validating the Dutch version (MoCA-D).

Method: We administered the MoCA-D to healthy control subjects and to elderly with MCI or dementia from a memory disorder outpatient clinic and a geriatric (outpatient) clinic (n = 30, 32, 37 respectively, age > or = 60).
