Optimization of a Sterile Processing Department Using Lean Six Sigma Methodology, Staffing Enhancement, and Capital Investment.

Background: Many hospitals and surgery centers have focused improvement efforts on operating room inefficiencies. A common inefficiency is missing and unusable surgical instrumentation, which can result in case delays and decreased effectiveness. Lean Six Sigma methodology, a set of process improvement tools focused on the reduction of waste and variation, has been used to identify and correct root causes of missing and unusable instrumentation.

Sonochemical Nitroxide-Mediated Polymerization: Harnessing Sonochemistry for Polymer Synthesis.

In polymer science, mechanochemistry is emerging as a powerful tool for materials science and molecular synthesis, offering novel avenues for controlled polymerization and post-synthetic modification. Building upon the previous research, nitroxide-mediated polymerization (NMP) is merged with mechanochemistry through the design of nitroxide-based mechanophore macroinitiators, pioneering the first instance of a sonochemical nitroxide-mediated-type polymerization. As NMP usually requires high temperatures, this study demonstrates that a sonochemical NMP-type process allows polymerization under reduced temperatures down to 55 °C.

Triphasic Bone Scintigraphy Is Not Useful in Diagnosis and May Delay Surgical Treatment of CRPS of the Hand.

Triphasic bone scintigraphy (TPBS) is often used to diagnose complex regional pain syndrome (CRPS). The primary aim of this study is to determine if the diagnosis of CRPS in patients with a positive TPBS (TPBS +ve) is accurate. A secondary aim is to determine if there was delay in treatment of patients who underwent TPBS compared to those who did not have a TPBS.

Formal -C-H-Fluorination of Pyridines and Isoquinolines through Dearomatized Oxazinopyridine Intermediates.

Organofluorine compounds, including fluorinated pyridines and isoquinolines, play a crucial role in pharmaceuticals, agrochemicals, and materials science. However, step-economic selective C-H-functionalization to access these fluorinated azaarenes is still underexplored, with selective -C-H-fluorination proving to be especially elusive. Here we present a practical method for formal -C-H-fluorination of pyridines and isoquinolines.

Anastomotic metabolic and bariatric surgeries with same-day discharge: 30-day outcomes of a cohort from a high-volume center in Canada.

Background: On the basis of our extensive experience in same-day discharge (SDD) sleeve gastrectomy, we extended this management strategy to anastomotic metabolic and bariatric surgeries (MBS).

Objectives: To retrospectively analyze early outcomes (≤30 d) after anastomotic MBS with planned SDD (≤12 hr).

Setting: University Hospital, Canada; Public Practice.
