OBJECTIVE: Despite surgical, technological, medical, and anesthetic improvements, patient outcomes following elective neurosurgical procedures can be associated with high morbidity. Enhanced recovery after surgery (ERAS) protocols are multimodal care pathways designed to optimize patient outcomes by addressing pre-, peri-, and post-operative factors. Despite significant data suggesting improved patient outcomes with the adoption of these pathways, development and implementation has been limited in the neurosurgical population...

Monoclonal antibodies undergo various forms of chemical transformation which have been shown to cause loss in efficacy and alteration in pharmacokinetic properties of these molecules. Such modified antibody molecules are known as variants. They also display physical properties such as charge that are different from intact antibody molecules. However, the difference in charge is very subtle and separation based on it is quite challenging. Charge variants are usually separated using ion-exchange column chromatography or isoelectric focusing...

Hydrophobic segments and amino moieties in polymeric nonviral gene vectors play important roles in overcoming a cas-cade of barriers for efficient gene delivery. However, it remains a great challenge to facilely construct well-defined multi-functional polymers through optimization of the amino and hydrophobic groups. Herein, we choose thiolactone chemistry to perform the ring opening reaction of varying hydrophobic groups-modified thiolactones by various amines to generate mercapto groups for further Michael addition reaction with poly[2-(acryloyloxy)ethyl methacrylate] (PAOEMA)...

Despite optimal surgery and appropriate first-line chemotherapy, ∼70%-80% of patients with epithelial ovarian cancer will develop disease relapse. The same modalities as used primarily are available for treatment of recurrent ovarian cancer (ROC). The rationale for repetitive surgery in ROC was based on a stable body of retrospective data; however, prospective data were missing. Now, preliminary data from the prospective AGO-DESKTOP III give evidence that surgery for ROC seems to be of benefit for selected patients with platinum-sensitive relapse undergoing complete resection...

Diabetic foot ulcers (DFUs) have a substantial impact on public health. The standard of care (SOC) for DFUs consists of a multidisciplinary approach involving glycemic control, wound care with debridement of necrotic tissue, application of a moist dressing, infection control, use of off-loading devices, and patient education. New therapeutic devices aim to target the extracellular matrix (ECM) that is impaired in DFU; however, there is insufficient data on the effectiveness of such therapies along with lack of evidence on their long-term effectiveness...
