The EXCITE trial: attributes of the Wolf Motor Function Test in patients with subacute stroke

The Wolf Motor Function Test (WMFT) has been used in rehabilitation studies of chronic stroke patients, but until now its psychometric properties have not been evaluated in patients with subacute stroke. Two hundred twenty-nine participants with subacute stroke (3-9 months postinjury) at 7 research sites met inclusion criteria for the EXCITE Trial and were randomized into immediate or delayed (by 1 year) constraint-induced movement therapy treatment. All evaluations were undertaken by assessors standardized in the administration of the WMFT and masked to treatment designation. Participants were also assessed using the Fugl Meyer Motor Assessment (FMA). Delayed group members had measurements repeated 2 weeks following baseline assessment to determine learning or exposure effects. The results demonstrate that the WMFT differentiated higher from lower functioning participants across sites; scores were uninfluenced by hand dominance or affected side. Women exhibited slower performance times than men. The Functional Ability scale (FAS) portion of the WMFT also revealed lower scores among lower functioning participants and women. Minimal changes were observed after repeating the WMFT among delayed group participants 2 weeks later. The FMA revealed similar results when the total group was divided into higher and lower functional levels at its midpoint score of 33. The WMFT discriminates higher from lower functioning participants tested across research sites. Comparable findings using the FMA support the criterion validity of the WMFT.     

Early brain injury in premature newborns detected with magnetic resonance imaging is associated with adverse early neurodevelopmental outcome

OBJECTIVE: To determine the neurodevelopmental outcome of prematurely born newborns with magnetic resonance imaging (MRI) abnormalities. STUDY DESIGN: A total of 89 prematurely born newborns (median age 28 weeks postgestation) were studied with MRI when stable for transport to MRI (median age, 32 weeks postgestation); 50 newborns were studied again near term age (median age, 37 weeks). Neurodevelopmental outcome was determined at 18 months adjusted age (median) using the Mental Development Index (Bayley Scales Infant Development II) and a standardized neurologic exam. RESULTS: Of 86 neonatal survivors, outcome was normal in 51 (59%), borderline in 22 (26%), and abnormal in 13 (15%). Moderate/severe MRI abnormalities were common on the first (37%) and second (32%) scans. Abnormal outcome was associated with increasing severity of white matter injury, ventriculomegaly, and intraventricular hemorrhage on MRI, as well as moderate/severe abnormalities on the first (relative risk [RR] = 5.6; P = .002) and second MRI studies (RR = 5.3; P = .03). Neuromotor abnormalities on neurologic examination near term age (RR = 6.5; P = .04) and postnatal infection (RR = 4.0; P = .01) also increased the risk for abnormal neurodevelopmental outcome. CONCLUSIONS: In premature newborns, brain abnormalities are common on MRI early in life and are associated with adverse neurodevelopmental outcome.     

Aortic valvuloplasty in the fetus: technical characteristics of successful balloon dilation

OBJECTIVES: To describe technical aspects of successful fetal aortic valvuloplasty, with particular attention to balloon size. STUDY DESIGN: We retrospectively reviewed all procedural records and echocardiograms pertaining to 26 attempts at fetal aortic valve dilation performed at a single center over a period of 4 years. We assessed the effect of valvuloplasty as determined by echocardiographic appearance at the time of intervention and in follow-up. RESULTS: In 20 of 26 fetuses who had technically successful aortic valve dilation (median balloon:annulus ratio=1.1), all had improved antegrade flow and 12 had at least mild regurgitation after dilation. Use of an oversized balloon was associated with the onset of moderate or severe aortic regurgitation, seen in 5 fetuses. This aortic regurgitation was well tolerated and improved through the remainder of gestation. CONCLUSIONS: These data imply that fetal aortic valves can be dilated safely with larger balloons than are commonly used for postnatal dilation. The observation of spontaneous improvement in postdilation aortic regurgitation further suggests that fetal valve tissue behaves uniquely.     

Benefits for employees with children with ADHD: findings from the Collaborative Employee Benefit Study

Parents of most children with attention-deficit hyperactivity disorder (ADHD) are employed. Employers have interest in decreasing employee absenteeism and improving workplace productivity, partly through employee benefits. The authors interviewed employers to (1) determine how they view the needs of employees with children with ADHD and (2) identify benefits that might help employees with children with ADHD. The authors carried out a systematic interview study of mainly family-friendly, large employers in four U.S. urban markets (Boston, Cleveland, Miami, Seattle). Multidisciplinary interview teams used a protocol to gather basic company information, benefit philosophy, current insurance and other employee benefits, and knowledge of ADHD and its impacts on employees. Initially, the interview team and then the larger project team reviewed all protocols for common themes. The authors interviewed staff of 41 employers (human resource managers, work/life program directors, benefits directors). Only 15 of 41 interviewees knew about ADHD, its prevalence, or its effects on parents. They had little knowledge of how differences in managed behavioral health may affect families' access to diagnostic and treatment services for ADHD, although most had experience with primary care management of depression among employees. Employers offer a variety of other benefits, including work/life and employee assistance programs, occasionally providing employees help with caring for a child with a mental health condition, on-site parent training programs, or assistance with child care. Other potentially useful employee benefits include flexible work and leave policies and information and referral services that can link parents with community programs. Although employers have limited awareness of ADHD and its potential effect on employees' work, this study identified opportunities to improve both health insurance and other benefits for employees with children with ADHD.
