Objective

To investigate response shift effects in spinal cord injury (SCI) over 5 years postinjury.

Design

Prospective cohort study observed at 1, 2, and 5 years post-SCI.

Setting

Specialized SCI centers.

Participants

Sample included 1125, 760, and 219 participants at 1, 2, and 5 years post-SCI (N = 2104). The study sample was 79% men; 39% were motor/sensory complete (mean age, 44.6±18.3y).

Interventions

Not applicable.

Main Outcome Measures

Patient-reported outcomes included the Medical Outcomes Study 36-Item Short-Form Health Survey version 2 and the Life Satisfaction-11 Questionnaire. Participant latent variable scores were adjusted for (1) potential attrition bias and (2) propensity scores reflecting risk of worse outcomes. The Oort structural equation modeling approach for detecting and accounting for response shift effects was used to test the hypothesis that people with SCI would undergo response shifts over follow-up.

Results

The study data comprised the time after FIM scores, an objective measure of motor and cognitive function, had improved and stabilized. Three latent variables (Physical, Mental, and Symptoms) were modeled over time. The response shift model indicated uniform recalibration and reconceptualization response shift effects over time. When adjusted for these response shift effects, Physical showed small true change improvements at 2- and 5-year follow-up, despite FIM stability.

Conclusions

We detected recalibration and reconceptualization response shift effects in 1- to 5-year follow-up of people with SCI. Despite stable motor and cognitive function, people with SCI are adapting to their condition. This adaptation reflects a progressive disconnection between symptoms and physical or mental health, and a real improvement in the Physical latent variable.  相似文献

A patient presented with a huge, pedunculated abdominal cystic lymphangioma arising from the quadrate lobe of the liver near the round ligament. Microscopically, dilated hepatic ducts with scant liver tissue could be recognized in the main cyst. A review of the literature reveals no previous report of a lymphangioma arising in this manner or from this area. Accepted: 31 June 1999  相似文献

Although medication errors in hospitals are common, medication errors that result in death or serious injury occur rarely. Even before the Institute of Medicine reported on medical errors in 1999, the American Academy of Pediatrics and its members had been committed to improving the health care system to provide the best and safest health care for infants, children, adolescents, and young adults. This commitment includes designing health care systems to prevent errors and emphasizing the pediatrician's role in this system. Human and device errors can lead to preventable morbidity and mortality. National and state legislative actions have heightened public awareness of these events. All involved persons, beginning with the physician and including every member of the health care team, must be better educated about and engaged in the several steps recommended to decrease these errors. The safe administration of medications to hospitalized infants and children requires additional specific safeguards that are above and beyond those for adult patients. Pediatricians should help hospitals develop effective programs for safely providing medications, reporting medication errors, and creating an environment of medication safety for all hospitalized pediatric patients.  相似文献

The presacral cystic teratoma in an infant is reported. The cyst consisted solely of central nervous system tissue. This pathologic finding is extremely rare. A review of the literature reveals no previous report of a teratoma arising in this manner.  相似文献
