    Abstract Pleurectomy and decortication (P/D) improve survival and quality of life in selected patients with malignant pleural mesothelioma. The operative procedure was not standardized until recently. The goal of the operation is to perform a macroscopic complete resection of the tumor. This often involves resection of the parietal and visceral pleura and invariably a partial or complete resection and prosthetic reconstruction of ipsilateral hemidiaphragm. We describe our operative planning and technique as well as outcomes of P/D reported in current literature.

    Abstract Purpose: Management of postoperative pain is a significant challenge following the Nuss procedure. Epidurals, PCAs, and newer analgesia modalities have been used elsewhere without demonstrating consistent improvement in the reported length of hospital stays (LOS). We reviewed a large single surgeon experience identifying three different methods of analgesia used over time to highlight marked improvement in patient LOS.
    Methods: IRB approval was obtained and patient clinical information was retrospectively reviewed from 2001 to 2017. The primary outcome variable was length of hospital stay. An expanded preoperative consultation reviews the issue of pain, the negative impact of anxiety on recovery, and our current success of shortened hospital stays with our patients.
    Results: One hundred and seventy-three patients representing three different analgesia approaches had a LOS of 4.4 days (epidural); 2.2 days (PCA/intercostal nerve block); and 1.6 days (scheduled oral pain meds/intercostal nerve blocks). The current LOS for patients is 1.0 day. Patients successfully stop using narcotics by the end of the first week postoperatively.
    Conclusions: Intraoperative intercostal nerve blocks, scheduled postoperative pain medications, and enhanced preoperative consultation aimed to educate patients about anxiety and reframe patient pain expectations have collectively decreased LOS, and reduced postoperative narcotic usage.
    Type of study: Clinical research LEVEL OF EVIDENCE: Level III.

    Abstract Background: We sought to evaluate the effect of center volume on patient survival.
    Methods: We performed a retrospective analysis on nationwide data from the Scientific Registry of Transplant Recipients provided by United Network for Organ Sharing pertaining to lung transplantation (LT) recipients transplanted between 2005 and 2013. Centers were categorized into 4 groups based on their annual volume as follows: less than 20, 20 to 29, 30 to 39, and greater than or equal to 40 LTs. Baseline characteristics were compared and Kaplan-Meier analysis was used to estimate survival.
    Results: A total of 13,506 adult recipients underwent LT during the study period. Of these, 2,491 (18.4%) patients were transplanted in centers with volume less than 20, 2,562 (19.0%) in centers with volume 20 to 29, 2,998 (22.2%) in centers with volume 30 to 39, and 5,455(40.4%) in centers with volume greater than or equal to 40. Survival was poorest in the lowest volume centers (1-year 81.4% vs 85.5% and 5-year 49.7% vs 56.5%, respectively).
    Conclusions: Post-LT survival in low volume centers is significantly lower than in high volume centers but the explanatory power of volume as a predictor of survival is low.

    Abstract Objective. The lung allocation score (LAS) resulted in a lung transplantation (LT) selection process guided by clinical acuity. We sought to evaluate the relationship between LAS and outcomes. Methods. We analyzed Scientific Registry of Transplant Recipient (SRTR) data pertaining to recipients between 2005 and 2012. We stratified them into quartiles based on LAS and compared survival and predictors of mortality. Results. We identified 10,304 consecutive patients, comprising 2,576 in each LAS quartile (quartile 1 (26.3-35.5), quartile 2 (35.6-39.3), quartile 3 (39.4-48.6), and quartile 4 (48.7-95.7)). Survival after 30 days (96.9% versus 96.8% versus 96.0% versus 94.8%), 90 days (94.6% versus 93.7% versus 93.3% versus 90.9%), 1 year (87.2% versus 85.0% versus 84.8% versus 80.9%), and 5 years (55.4% versus 54.5% versus 52.5% versus 48.8%) was higher in the lower groups. There was a significantly higher 5-year mortality in the highest LAS group (HR 1.13, p = 0.030, HR 1.17, p = 0.01, and HR 1.17, p = 0.02) comparing quartiles 2, 3, and 4, respectively, to quartile 1. Conclusion. Overall, outcomes in recipients with higher LAS are worse than those in patients with lower LAS. These data should inform more individualized evidence-based discussion during pretransplant counseling.

    Abstract Small iron oxide and Co-doped iron oxide nanoparticles (NPs) were synthesized in a commercial amphiphilic block copolymer, poly(ethylene oxide)-b-poly(methacrylic acid) (PEO 68-b-PMAA8), in aqueous solutions. The structure and composition of the micelles containing guest molecules (metal salts) or NPs (metal oxides) were studied using transmission electron microscopy, dynamic light scattering, X-ray photoelectron spectroscopy, and X-ray powder diffraction. The enlarged micelle cores after incorporation of metal salts are believed to be formed by both PMAA blocks containing metal species and penetrating PEO chains. The nanoparticle size distributions in PEO 68-b-PMAA8 were determined using small-angle X-ray scattering (SAXS) in bulk. Two independent methods for SAXS data interpretation for comprehensive analysis of volume distributions of metal oxide NPs showed presence of both small particles and larger entities containing metal species which are ascribed to organization of block copolymer micelles in bulk. The magnetometry measurements revealed that the NPs are superparamagnetic and their characteristics depend on the method of the NP synthesis. The important advantage of the PEO 68-b-PMAA8 stabilized magnetic nanoparticles described in this paper is their remarkable solubility and stability in water and buffers.
