Multiresolution Data Acquisition and Detection in Functional MRI

In an investigation of a multiresolution and multistaged approach in functional MRI, the relationship between spatial resolution and detection of functional activation is examined. The difference between functional detection and mapping is defined, and a multiresolution approach to functional detection is analyzed by constructing simple theoretical and experimental models simulating variations of in-plane resolution. Experimentally measured blood oxygenation level-dependent (BOLD) signal changes as well as BOLD contrast-to-noise ratio (CNR) with respect to different spatial resolutions are compared with results from theoretical predictions and simulation. From both an experimental and a theoretical perspective, it is shown that BOLD CNR and, thus, the concomitant detection of the functional activation are maximized when the resolution matches the size of activation.     

Testing the functional status model in patients with chronic obstructive pulmonary disease

BACKGROUND: Patients with chronic obstructive pulmonary disease usually experience gradual functional status degradation, especially dyspnoea, which may affect their daily activities and, eventually, quality of life. A full understanding of both their physiological and psychological functional status is therefore beneficial for effective treatment and helping patients regain or maintain control of their lives. METHOD: Based on a non-experimental research design, 138 patients to test a hypothesized model of functional status in patients with chronic obstructive pulmonary disease, using structural equation modelling, were recruited from a medical center. Data were collected using questionnaires, 6-minute walking distance measurement, and pulmonary function test results recorded in patients' medical records. The proposed functional status model incorporated the exogenous variables disease severity and dyspnoea, and the endogenous variables age, exercise tolerance, fatigue, depression, anxiety, health perception and functional performance. Structural equation modelling with the lisrel software was used to establish a functional status model with those exogenous and endogenous variables. RESULTS: The results indicated a good fit between the proposed functional status model and the data collected [chi(2) = 8.84, P = 0.64, chi(2)/d.f. = 0.80, Goodness of Fit Index (GFI) = 0.98, adjusted GFI (AGFI) = 0.95, root mean square residual (RMR) = 0.04, Critical N (CN) = 384.26]. Coefficients for paths in the functional status model all demonstrated statistical significance. CONCLUSION: The functional status model was shown to consist of functional performance, functional capacity and other concepts, including disease severity, dyspnoea, age, exercise tolerance, fatigue, depression, anxiety and health perception. These results can be used to develop a suitable functional status model for chronic obstructive pulmonary disease, and could act as a reference for formulating future strategies and intervention procedures for further development of functional status.     

Short Physical Performance Battery: Response to Pulmonary Rehabilitation and Minimal Important Difference Estimates in Patients With Chronic Obstructive Pulmonary Disease

ObjectiveTo determine the response to a pulmonary rehabilitation (PR) program and minimal important differences (MIDs) for the Short Physical Performance Battery (SPPB) subtests and SPPB summary score in patients with chronic obstructive pulmonary disease (COPD).DesignRetrospective analysis using distribution- and anchor-based methods.SettingPR center in the Netherlands including a comprehensive 40-session 8-week inpatient or 14-week outpatient program.ParticipantsA total of 632 patients with COPD (age, 65±8y; 50% male; forced expiratory volume in the first second=43% [interquartile range, 30%-60%] predicted).InterventionsNot applicable.Main Outcome MeasureBaseline and post-PR results of the SPPB, consisting of 3 balance standing tests, 4-meter gait speed (4MGS), and 5-repetition sit-to-stand (5STS). The chosen anchors were the 6-Minute Walk Test and COPD Assessment Test. Patients were stratified according to their SPPB summary scores into low-performance, moderate-performance, and high-performance groups.Results5STS (∆=−1.14 [−4.20 to −0.93]s) and SPPB summary score (∆=1 [0-2] points) improved after PR in patients with COPD. In patients with a low performance at baseline, balance tandem and 4MGS significantly increased as well. Based on distribution-based calculations, the MID estimates ranged between 2.19 and 6.33 seconds for 5STS and 0.83 to 0.96 points for SPPB summary score.ConclusionsThe 5STS and SPPB summary score are both responsive to PR in patients with COPD. The balance tandem test and 4MGS are only responsive to PR in patients with COPD with a low performance at baseline. Based on distribution-based calculations, an MID estimate of 1 point for the SPPB summary score is recommended in patients with COPD. Future research is needed to confirm MID estimates for SPPB in different centers.

Efficacy of eletriptan in migraine-related functional impairment: functional and work productivity outcomes

OBJECTIVE: To provide a multidimensional assessment of the extent of functional impairment during an acute migraine attack, and of the improvement in functioning in response to treatment, using 4 concurrently administered scales: the 7-item work productivity questionnaire (PQ-7), the functional assessment in migraine (FAIM) activities and participation (FAIM-A&P) subscale, the FAIM-impact of migraine on mental functioning (FAIM-IMMF) subscale, and the traditional 4-point global functional impairment scale (FIS). METHODS: Outpatients with an International Classification of Headache Disorders diagnosis of migraine were randomized to double-blind treatment of a single attack with either oral eletriptan 20 mg (n = 192) once-daily, eletriptan 40 mg (N = 213) once-daily, or placebo (n = 208). Patients were encouraged to take study medication as soon as they were sure they were experiencing a typical migraine headache, after the aura phase (if present) had ended. Patients with moderate-to-severe functional impairment were identified on each of the 4 disability scales, and 2-hour functional response was compared between treatments. RESULTS: At baseline, the PQ-7 and FAIM-IMMF items that assessed ability to perform tasks requiring concentration, sustained work or attention, and ability to think quickly or spontaneously, were especially sensitive to the effects of mild headache pain, with 27% to 48% of patients (n = 92-112) reporting moderate-to-severe impairment. Only 11.3% of patients (n = 112) reported this level of impairment due to mild pain on the FIS. Functional response at 2 hours was significantly higher on eletriptan 40 mg versus placebo on the FAIM-A&P (63% vs 36%; n = 218; P < .0001); on the PQ-7 (56% vs 34%; n = 116; P= .0052); and on the FAIM-IMMF (50% vs 34%; n = 215; P= .017). These rates were all lower than the functional response rates on the FIS for eletriptan 40 mg (75%) and eletriptan 20 mg (70%) versus placebo (45%; P < .001). Conclusions.-In this exploratory analysis, use of multidimensional scales was found to provide a sensitive measure of headache-related functional impairment, especially for detecting clinically meaningful cognitive effects, and for detecting drug versus placebo differences.
