Setting Measurement-Based Care in Motion: Practical Lessons in the Implementation and Integration of Measurement-Based Care in Psychiatry Clinical Practice.

Measurement-based care (MBC) involves the systematic use of standardized measurements to inform treatment decisions. MBC can enhance clinical decision-making and quality of care by prompting personalized changes in treatment based on measured patient outcomes. MBC can also promote more precise communications between patients and clinicians around individual patient care.

Applying Lean Six Sigma to Improve Depression Screening and Follow-Up in Oncology Clinics.

Depression is a common and serious illness that impairs the health of individuals and societies globally. It is associated with a significant economic burden, with productivity losses exceeding $40 billion dollars annually in the United States (U.S.

Exercise Training in Amnestic Mild Cognitive Impairment: A One-Year Randomized Controlled Trial.

Background: The current evidence is inconclusive to support the benefits of aerobic exercise training (AET) for preventing neurocognitive decline in patients with amnestic mild cognitive impairment (aMCI).

Objective: To examine the effect of a progressive, moderate-to-high intensity AET program on memory and executive function, brain volume, and cortical amyloid-β (Aβ) plaque deposition in aMCI patients.

Methods: This is a proof-of-concept trial that randomized 70 aMCI patients to 12 months of AET or stretching and toning (SAT, active control) interventions.

Reduced global brain metabolism but maintained vascular function in amnestic mild cognitive impairment.

Amnestic mild cognitive impairment represents an early stage of Alzheimer's disease, and characterization of physiological alterations in mild cognitive impairment is an important step toward accurate diagnosis and intervention of this condition. To investigate the extent of neurodegeneration in patients with mild cognitive impairment, whole-brain cerebral metabolic rate of oxygen in absolute units of µmol O/min/100 g was quantified in 44 amnestic mild cognitive impairment and 28 elderly controls using a novel, non-invasive magnetic resonance imaging method. We found a 12.

Dynamic cerebral autoregulation and tissue oxygenation in amnestic mild cognitive impairment.

Background: Vascular disease and dysfunction are associated with the higher risk of Alzheimer's disease hypothetically due to cerebral hypoperfusion. Brain perfusion is protected by cerebral autoregulation, which, under normal conditions, maintains a constant cerebral blood flow and brain tissue oxygenation.

Objective: To determine whether dynamic regulation of cerebral blood flow and tissue oxygenation is impaired in patients with amnestic mild cognitive impairment (aMCI).

Global brain hypoperfusion and oxygenation in amnestic mild cognitive impairment.

Background: To determine if global brain hypoperfusion and oxygen hypometabolism occur in patients with amnestic mild cognitive impairment (aMCI).

Methods: Thirty-two aMCI and 21 normal subjects participated. Total cerebral blood flow (TCBF), cerebral metabolic rate of oxygen (CMRO2), and brain tissue volume were measured using color-coded duplex ultrasonography (CDUS), near-infrared spectroscopy (NIRS), and MRI.

Association of common genetic variants in GPCPD1 with scaling of visual cortical surface area in humans.

Visual cortical surface area varies two- to threefold between human individuals, is highly heritable, and has been correlated with visual acuity and visual perception. However, it is still largely unknown what specific genetic and environmental factors contribute to normal variation in the area of visual cortex. To identify SNPs associated with the proportional surface area of visual cortex, we performed a genome-wide association study followed by replication in two independent cohorts.

Distinctive disruption patterns of white matter tracts in Alzheimer's disease with full diffusion tensor characterization.

To characterize the white matter structural changes at the tract level and tract group level, comprehensive analysis with 4 metrics derived from diffusion tensor imaging (DTI), fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AxD) and radial diffusivity (RD), was conducted. Tract groups, namely limbic, commissural, association, and projection tracts, include white matter tracts of similar functions. Diffusion tensor imaging data were acquired from 61 subjects (26 Alzheimer's disease [AD], 11 subjects with amnestic mild cognitive impairment [aMCI], and 24 age-matched controls).

Forebrain-dominant deficit in cerebrovascular reactivity in Alzheimer's disease.

Epidemiologic evidence and postmortem studies of cerebral amyloid angiopathy suggest that vascular dysfunction may play an important role in the pathogenesis of Alzheimer's disease (AD). However, alterations in vascular function under in vivo conditions are poorly understood. In this study, we assessed cerebrovascular-reactivity (CVR) in AD patients and age-matched controls using CO(2)-inhalation while simultaneously acquiring Blood-Oxygenation-Level-Dependent (BOLD) MR images.

An open-label study of memantine treatment in 3 subtypes of frontotemporal lobar degeneration.

There are currently no Food and Drug Administration-approved treatments for frontotemporal lobar degeneration (FTLD). The objectives of this study were to explore the tolerability of memantine treatment in FTLD and to monitor for possible effects on behavior, cognition, and function. Forty-three individuals who met clinical criteria for FTLD [21 with frontotemporal dementia (FTD), 13 with semantic dementia (SD), and 9 with progressive nonfluent aphasia (PA)] received 26 weeks of open-label treatment with memantine at a target dose of 20 mg daily.

Altered cerebral hemodynamics in early Alzheimer disease: a pilot study using transcranial Doppler.

Cerebrovascular disease may contribute to the development and progression of Alzheimer's disease (AD). This study investigated whether impairments in cerebral hemodynamics can be detected in early-stage AD. Nine patients with mild AD and eight cognitively normal controls matched for age underwent brain magnetic resonance imaging and neuropsychological evaluation, followed by assessment of steady-state cerebral blood flow velocity (CBFV, transcranial Doppler), blood pressure (BP, Finapres), and cerebrovascular resistance index (BP/CBFV).

Arterial-cardiac baroreflex function: insights from repeated squat-stand maneuvers.

To assess baroreflex function under closed-loop conditions, a new approach was used to generate large and physiological perturbations in arterial pressure. Blood pressure (BP) and R-R interval were recorded continuously in 20 healthy young (33 +/- 8 yr) and eight elderly subjects (66 +/- 6 yr). Repeated squat-stand maneuvers at the frequencies of 0.

Cerebral blood volume in Alzheimer's disease and correlation with tissue structural integrity.

A vascular component is increasingly recognized as important in Alzheimer's disease (AD). We measured cerebral blood volume (CBV) in patients with probable AD or Mild Cognitive Impairment (MCI) and in elderly non-demented subjects using a recently developed Vascular-Space-Occupancy (VASO) MRI technique. While both gray and white matters were examined, significant CBV deficit regions were primarily located in white matter, specifically in frontal and parietal lobes, in which CBV was reduced by 20% in the AD/MCI group.

A direct functional measure to help ascertain optimal level of residential care.

A brieF direct measure oF daily living skills might help place cognitively impaired elders in suitable living environments. In this study, the Test oF Everyday Functional Abilities (TEFA) as a possible adjunctive measure was investigated. The authors recruited 77 cognitively impaired persons in independent living (IL; N = 26), assisted living (AL; N = 25), and dementia special care (SC; N = 26) units.

Caregivers' perceptions of dementia patients' functional ability.

Dementia patients' caregivers often provide information about patients' daily functioning, but little is known about factors influencing caregivers' perceptions. Baseline data from an intervention trial were used to compare caregiver estimates of dementia patients' performance with their actual performance of instrumental activities of daily living (IADLs) and to assess relationships between measures of caregiver responses to caregiving, self-perceived sense of self-efficacy, and depression. We also assessed patient cognition, overall function and behavioral disturbance, and caregivers' perceptions of their patients' behavior as manipulative or deliberate.

A randomized, controlled study of an Alzheimer's caregiver skills training program.

This study was an attempt to improve the quality of the relationship between dementia caregivers and their loved ones by decreasing the gap between caregivers' expectations and patients' actual functional abilities and by teaching supportive skills. Although a group of 49 caregiver-patient dyads were recruited, the outcome measures of only those dyads (47) that completed the week seven session were used for analysis. Half of the dyads were randomized to an intervention group and the other half to a waiting list.

Responsiveness of the quality of life in late-stage dementia scale to psychotropic drug treatment in late-stage dementia.

Background: We report on the responsiveness of a previously validated quality-of-life scale, the Quality of Life in Late-Stage Dementia scale (QUALID), as an outcome measure in a clinical trial of two psychotropic medications.

Methods: Secondary analyses were conducted comparing outcome measures used in a randomized double-blind trial of two antipsychotics (olanzapine and risperidone) for the treatment of dementia-related behavioral symptoms. The QUALID was completed for 31 of the patients in addition to several measures of behavior-related dementia symptoms including the Neuropsychiatric Inventory, the Withdrawn Behavior subscale of the Multidimensional Observation Scale for Elderly Subjects, the Mini-Mental State Examination, and the Clinical Global Impression.

Caregiver attribution and resentment in dementia care.

The caregivers of 37 patients with a dementing illness completed rating scales regarding the frequency and severity of their care recipient's general behavioral disturbance and manipulative behaviors, as well as their own resentment and depression. Caregivers were randomized to a four-week psychoeducational group intervention or control group to investigate the effect of dementia caregiving education on the caregiving experience. Findings indicated that, while care recipient behavioral disturbance was correlated with caregiver resentment and depression, the primary relationship was between behaviors perceived by the caregiver as manipulative or willful and caregiver resentment and depression.

Can alzheimer's disease and dementias with Lewy bodies be distinguished clinically?

To determine if Alzheimer's disease (AD), its Lewy body (LB) variant (LBV), and diffuse LB disease (DLBD) are distinguishable at initial clinical evaluation, data from autopsy-confirmed AD, LBV, and DLBD were examined. No significant differences were found in age at onset, age at death, total duration of illness, duration of illness before initial visit, duration of illness from initial visit to death, or severity of illness at initial evaluation. Hallucinations and delusions were significantly more frequent for LBV and DLBD, respectively, than for AD, and falls were more frequent for DLBD than for AD.

A double-blind comparison of olanzapine versus risperidone in the acute treatment of dementia-related behavioral disturbances in extended care facilities.

Background: In addition to demonstrating their superiority to placebo, there is a need to compare the relative efficacy and side effects of atypical neuroleptics for the acute treatment of dementia-related behavioral disturbances in residents of long-term care facilities.

Method: In a double-blind parallel study allowing dose titration over 14 days, 39 agitated persons with DSM-IV dementia who were residing in long-term care facilities were administered olanzapine (N = 20) or risperidone (N = 19) as acute treatment. Drug was administered once a day at bedtime.

The quality of life in late-stage dementia (QUALID) scale.

Objectives: To develop a valid and reliable instrument for rating quality of life in persons with late-stage Alzheimer's disease and other dementing illnesses.

Design: A group of clinicians with extensive experience in dealing with dementia patients developed by consensus the Quality of Life in Dementia Scale (QUALID), an 11-item scale. The window of observation for each subject was 7 days.

Comparison of functional and cognitive donepezil effects in Alzheimer's disease.

Donepezil has been shown to improve aspects of cognitive functioning in persons with Alzheimer's disease (AD), but its impact on instrumental activities of daily living has received little attention. In a within-subject design, 24 community-dwelling persons with AD were treated with open-label donepezil over a 12-month period. To assess functional abilities, a brief, objective measure of instrumental activities of daily living skills was used (Texas Functional Living Scale; TFLS).

Performance-Based instrument to assess functional capacity in dementia: The Texas Functional Living Scale.

Objective: The Texas Functional Living Scale (TFLS) is a new performance-based measure of functional abilities with an emphasis on instrumental activities of daily living skills that is brief and weighted toward cognitive tasks. The purpose of this study was to examine its psychometric properties and clinical utility in patients with Alzheimer disease (AD) and normal elderly individuals.

Background: Measures of daily functional capacities used in patients with dementia often rely upon informant-based behavioral ratings or lengthy assessments of instrumental activities of daily living.

Impact of family visits on agitation in residents with dementia.

In an investigation of the impact of family visits on the behavior of 30 residents in dementia special care units, we found on direct observation that agitation decreased significantly during visits, but returned to the previous level within 30 minutes. No significant differences were found between visits by spouses or adult children. The premorbid quality of relationship was unrelated to family visitor enjoyment of visits or to differences between agitation level before and after visits.
