Application of a Quick Response Code as an Alternative Method to Provide Pediatric Cast Care Instructions.

Background: There is a growing need to improve patient education for nonsurgical fracture care in children. A Quick Response (QR) code was used as an alternative method to provide cast care instructions in our outpatient fracture clinic. We evaluated satisfaction and examined the convenience and impact this might have on the child's casting experience.

Meniscal Repairs in the Adolescent Knee: Can the Number of Fixation Sites Improve Outcomes?

Background: Meniscal pathology in children and adolescents is now a common occurrence because of their ever-increasing participation in youth sports.

Purpose: To investigate the outcomes of arthroscopic meniscal repair in an adolescent cohort and analyze the variables that may affect outcomes, specifically the number of fixation sites utilized during repair.

Study Design: Case series; Level of evidence, 4.

Utility of Bioabsorbable Fixation of Osteochondral Lesions in the Adolescent Knee: Outcomes Analysis With Minimum 2-Year Follow-up.

Background: Osteochondral lesions (OCLs) of the knee, whether occurring secondary to osteochondritis dissecans or a traumatic osteochondral fracture, are commonly encountered in the pediatric and adolescent population. Given the potential for healing in this population, coupled with adequate surgical reduction and stability of OCL fixation, an opportunity exists to avoid a major restorative procedure and the associated substantial costs and potential morbidity.

Purpose: To analyze the outcomes of bioabsorbable fixation of OCLs in the adolescent knee at a minimum of 2 years.

Fat Quantity and Quality, as Part of a Low-Fat, Vegan Diet, Are Associated with Changes in Body Composition, Insulin Resistance, and Insulin Secretion. A 16-Week Randomized Controlled Trial.

Macronutrient composition of the diet influences the development of obesity and insulin resistance. The aim of this study was to assess the role of dietary fat quantity and fatty acid composition in body composition, insulin resistance, and insulin secretion. An open parallel randomized trial design was used.

Measuring DNA repair incision activity of mouse tissue extracts towards singlet oxygen-induced DNA damage: a comet-based in vitro repair assay.

During the past two decades, the comet-based in vitro DNA repair assay has been used regularly to measure base excision repair (BER)-related DNA incision activity. Most studies focus on the assessment of BER in human lymphocytes or cultured cells by estimating the activity of a cell extract on substrate DNA containing specific lesions such as 8-oxoguanine. However, for many 'real-life' studies, it would be preferable to measure BER in the tissues of interest instead of using in vitro models or surrogate 'tissues' such as lymphocytes.
