An International Consensus Survey among Pediatric Surgeons on the Role of Appendectomy in Malrotation.

Introduction: Ladd's procedure, originally described in 1936 for the treatment of malrotation, does not traditionally include appendectomy as a standard step. We conducted a multinational survey to investigate the current consensus on the role of appendectomy in Ladd's procedure.

Methodology: An anonymous online survey was distributed to pediatric surgeons worldwide.

Lessons learned from the COVID-19 pandemic: Improving initial investigations with the implementation of a COVID-19 blood request panel.

Background: During the COVID-19 pandemic, the Hillingdon Hospitals NHS Foundation Trust produced trust guidelines for the initial blood investigation of COVID-19 inpatients. However, insufficient education meant inconsistent adherence to this guidance.

Objective: To examine whether the implementation of a COVID-19 blood request panel improves adherence to local trust guidelines.

Solidification/stabilisation of Pb (II) and Cu (II) containing wastewater in cement matrix.

This study reported solidification/stabilisation of lead and copper-laden fly ash (adsorbent) utilising cement as binder for their ultimate disposal. The Pb (II) and Cu (II) loaded fly ash was successfully immobilised within the cement matrix without presence of any chemical agents. A retardation of 80-100 min in the setting time of cement paste was noticed on the addition of metal-laden fly ash attributed to the presence of metal ions.
