RESUMEN
OBJECTIVES: Primary objective: describe rates of 30-days unplanned readmission following outpatient resection of oral cavity cancer. Secondary objective: evaluate for patient and treatment factors associated with readmission. METHODS: Retrospective, dual-institution cohort study of 2 tertiary care referral centers involving adult patients undergoing resection of oral cavity cancer with plans for same-day discharge. Consecutive sample of 77 patients included. Primary outcome was unplanned readmission to emergency room or inpatient stay in the 30 days following surgery. Comparison testing was used between return and non-return groups. RESULTS: Among 77 patients treated with outpatient surgery for oral cavity cancer, 19 (25%) returned to the hospital within 30 days. Among the reasons for return, 16 (80%) were directly related to surgery, and 4 (20%) were related to perioperative medical complications not directly related to a surgical site. Among the 25 patients also undergoing sentinel lymph node biopsy with their oral cavity resection, none returned to the hospital for neck-related complications. While most patients could be safely observed and discharged after return to the hospital, 8 patients (10%) required inpatient readmission. No significant differences between return and non-return groups were identified, although there was a trend toward shorter driving distance from hospital for the return group (47.6 miles vs. 69.5 miles, P = 0.097). CONCLUSION: Unplanned return to the hospital following outpatient oral cavity resection is prevalent and primarily driven by postoperative primary resection site concerns. Among patients selected for same day discharge, no definite population at highest risk of unplanned return was identified.

OBJECTIVES: To demonstrate the effect of drug induced sleep endoscopy (DISE) on intra-operative decision making during pediatric sleep surgery for obstructive sleep apnea (OSA). METHODS: A retrospective chart review was performed on pediatric (3-17 years) patients with moderate-to-severe OSA (7.2-71.8) who underwent drug induced sleep endoscopy at the time of initial sleep surgery. The characteristics evaluated included age, race, gender, site of obstruction, type of surgical intervention, pre- and post-operative apnea and hypopnea index. Of the 26 patients that were identified, 18 had both a pre- and post-operative polysomnograms result. RESULTS: All patients underwent DISE immediately prior to surgical treatment. The mean pre-operative AHI for the 18 patients with post-operative polysomnogram results was 21.3 (7.2-71.8). The mean post-operative AHI for the 18 patients was 7.6 (0.7-25.1). There was a significant difference between pre- and post-operative AHI (p < 0.001). Of the 26 patients, the most common area of collapse was the soft palate, occurring in 17/26 (65.4%) patients. Base of tongue involvement was found to be present in 11/26 (42.3%) patients, and the epiglottis was involved in 4/26 (15.4%). Evidence of multilevel collapse was observed in 6/26 (23.1%) patients. Patients observed to have palatal collapse underwent a pharyngoplasty (20/26; 76.9%) at the time of adenotonsillectomy. Three (11.5%) patients underwent a tongue reduction. CONCLUSION: This study provides additional evidence that DISE can affect intra-operative decision making, with the potential for improved post-operative outcomes. A randomized controlled study is needed to determine if these outcomes are better than what can be achieved without DISE.

Autologous vein grafts are commonly used for coronary and peripheral artery bypass but have a high incidence of intimal hyperplasia (IH) and failure. We present a nanopolyplex (NP) approach that efficiently delivers a mitogen-activated protein kinase (MAPK)-activated protein (MAPKAP) kinase 2 inhibitory peptide (MK2i) to graft tissue to improve long-term patency by inhibiting pathways that initiate IH. In vitro testing in human vascular smooth muscle cells revealed that formulation into MK2i-NPs increased cell internalization, endosomal escape, and intracellular half-life of MK2i. This efficient delivery mechanism enabled MK2i-NPs to sustain potent inhibition of inflammatory cytokine production and migration in vascular cells. In intact human saphenous vein, MK2i-NPs blocked inflammatory and migratory signaling, as confirmed by reduced phosphorylation of the posttranscriptional gene regulator heterogeneous nuclear ribonucleoprotein A0, the transcription factor cAMP (adenosine 3',5'-monophosphate) element-binding protein, and the chaperone heat shock protein 27. The molecular effects of MK2i-NPs caused functional inhibition of IH in human saphenous vein cultured ex vivo. In a rabbit vein transplant model, a 30-min intraoperative graft treatment with MK2i-NPs significantly reduced in vivo IH 28 days posttransplant compared with untreated or free MK2i-treated grafts. The decrease in IH in MK2i-NP-treated grafts in the rabbit model also corresponded with decreased cellular proliferation and maintenance of the vascular wall smooth muscle cells in a more contractile phenotype. These data indicate that nanoformulated MK2 inhibitors are a promising strategy for preventing graft failure.
