Practiced in China for more than 2000 years, acupuncture has recently gained increased attention in the United States as an alternative treatment approach for a variety of medical conditions. Despite its growing prevalence and anecdotal reports of success among pediatric populations, few empirically based studies have assessed the efficacy of acupuncture for children and adolescents. This article presents a review of the current literature, including a systematic appraisal of the methodological value of each study and a discussion of potential benefits and adverse effects of acupuncture. While acupuncture holds great promise as a treatment modality for diverse pediatric conditions, a significant amount of additional research is necessary to establish an empirical basis for the incorporation of acupuncture into standard care.

Antibody−drug conjugates (ADCs) have demonstrated great therapeutic potential due to their ability to target the delivery of potent cytotoxins. However, the heterogeneous nature of conventional drug conjugation strategies can affect the safety, efficacy, and stability of ADCs. Site-specific conjugations can resolve these issues, but often require genetic modification of Immunoglobulin G (IgG), which can impact yield or cost of production, or require undesirable chemical linkages. Here, we describe a near-traceless conjugation method that enables the efficient modification of native IgG, without the need for genetic engineering or glycan modification. This method utilizes engineered variants of sortase A to catalyze noncanonical isopeptide ligation. Sortase A was fused to an antibody-binding domain to improve ligation efficiency. Antibody labeling is limited to five lysine residues on the heavy chain and one on the light chain of human IgG1. The ADCs exhibit conserved antigen and Fc-receptor interactions, as well as potent cytolytic activity.
