In this issue of Clinics in Perinatology, guest editors KuoJen Tsao and Hanmin Lee bring their considerable expertise to the topic of Fetal and Neonatal Surgery. Provides in-depth reviews on the latest updates in Fetal and Neonatal Surgery, providing actionable insights for clinical practice. Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field; Authors synthesize and distill the latest research and practice guidelines to create these timely topic-based reviews.

Experts in the field of minimally invasive surgery have come together to provide the most up-to-date clinical review of the topic. The Guest Editors have created an issue with comprehensive coverage of relevant topics in the field, with articles devoted to the following: Fetal Surgery; Robotics; NOTES; Minimally Invasive PDA Ligation; CDH/Eventration Esophageal Atresia/TEF; Thoracic lesions: Congenital Lung Lesions; Hepato-Biliary surgery Fundoplication/g-tube; Hernia; Hirschsprung's Disease; Imperforate Anus; and Minimally Invasive Urology. Readers will come away with the clinical infomration they need to help inform them as they utilize the most current technologies and minimally invasive techniques in the neonatal patient.

The Guest Editors have assembled a list of topics that provide state-of-the-art coverage on fetal surgery. Topics covered include fetal cardiac intervention, abdominal wall defects, NEC, esophageal atresia, and spinia bifida.? Some articles provide the clinical basics, like general concepts of fetal surgery, while others provide a detailed look at CDH in utero, CDH post natal, ECMO/placenta, stem cell, and anorectal malformations.

This issue of Clinics in Perinatology, guest edited by Dr. Hanmin Lee, examines the topic of Fetal Surgery. The issue begins with an overview, including the history of fetal surgery, ethical implications, and maternal management and outcome. Imaging (including Ultrasound, MRI, and Echocardiology) and Specific Diseases (including Congenital Diaphragmatic Hernia, Fetal Lung Lesions, Obstructive Uropathy, TTTS, MMC, TRAP and other discordant twins, and Congenital Cardiac Anomalies) are also examines. The issue concludes with a look at research and future directions, including Stem Cell Transplant/Gene Therapy, Consortiums/Registries, and Fetal Tissue Engineering.

The National Institute of Standards and Technology NISTIR 7772, "Information Model for Disassembly for Reuse, Recycling, and Remanufacturing" addresses the disassembly process and how it is an essential activity in the mid and end of a product's service life cycle. Maintenance is a mid product life activity, which involves disassembly, cleaning, repair, replace, inspection, and reassembly. Remanufacture, reuse, and recycle are activities at the end of a product's service life. The main purpose of performing these activities is to increase sustainability, which includes reduce environmental impact, increase economic, and extend societal benefits to meet the goal of sustainable development. This report describes a developed disassembly information model. It is an integrated information model with the following key components: feature, tolerance, workpiece, material content, equipment, and process. The model supports the modeling of disassembly features, sequence, operations, decision making, and workflow. Case study using real products and their specific disassembly processes is provided to verify the developed model.
