Objective: This ancillary study's purpose is to describe the relationship between dose of treatment and body mass index (BMI) outcomes in a tele-behavioral health program delivered in the IDeA States Pediatric Clinical Trials Network to children and their families living in rural communities.
Methods: Participants randomized to the intervention were able to receive 26 contact hours (15 hr of group sessions and 11 hr of individual sessions) of material focused on nutrition, physical activity, and behavioral caregiver training delivered via interactive televideo. Dose of the intervention received by child/caregiver dyads (n = 52) from rural areas was measured as contact hours.
Article Synopsis
- Lumbar fusion and lumbar disk replacement (LDR) are common surgical options for chronic low back pain, but this study focused on comparing their postoperative management costs over two years.
- A total of 1,660 patients were studied, revealing that the average cost for postoperative care was approximately $2,832 per patient, with similar costs for both procedures.
- The main cost driver was physical therapy, highlighting that while LDR may have a shorter recovery, it does not significantly reduce long-term healthcare expenses compared to lumbar fusion.
Introduction: Little is known about the association between age and fecal ostomy surgery trends over time. We aim to 1) determine the rate of fecal ostomy operations over time and 2) compare rates of colostomy formation between patients older and younger than 65 y.
Materials And Methods: Retrospective multi-institutional cohort study of patients ≥18 y who underwent colorectal resection between 2003 and 2014 using the Nationwide Inpatient Sample database.
Purpose: To evaluate the sites where the tether breaks in vertebral body tethering (VBT) cases.
Methods: Intraoperative evaluation of broken tethers in patients who had anterior revision.
Inclusion Criteria: anterior revision of VBT cases with explantation of the full implant and photo documentation.
