Using Patient Demographics and Statistical Modeling to Predict Knee Tibia Component Sizing in Total Knee Arthroplasty.

Background: Preoperative planning is important to achieve successful implantation in primary total knee arthroplasty (TKA). However, traditional TKA templating techniques are not accurate enough to predict the component size to a very close range.

Methods: With the goal of developing a general predictive statistical model using patient demographic information, ordinal logistic regression was applied to build a proportional odds model to predict the tibia component size.

The Treatment for Adolescents With Depression Study (TADS): outcomes over 1 year of naturalistic follow-up.

Objective: The Treatment for Adolescents With Depression Study (TADS) evaluates the effectiveness of fluoxetine, cognitive-behavioral therapy (CBT), and their combination in adolescents with major depressive disorder. The authors report effectiveness outcomes across a 1-year naturalistic follow-up period.

Method: The randomized, controlled trial was conducted in 13 academic and community sites in the United States.

Gender, kinship and caregiver burden: the case of community-dwelling memory impaired seniors.

Background: This study examined whether there were gender and kinship (spouse, child, more distant relative) differences in caregiver burden. It further examined the constellation of gender and kinship by examining whether adult daughter caregivers experienced greater burden compared to wives, husbands, sons, and other more distant relatives.

Methods: The sample consisted of 305 family caregivers of memory-impaired individuals who were age 70 years or older and resided in non-institutional settings in Arkansas.
