Article Synopsis
- * A notable 108% increase in TKA procedures was observed, alongside improvements in certain health conditions and significantly reduced hospital stays longer than 2 days.
- * However, the rate of adverse events after surgery increased, with older age, male sex, and certain chronic health issues identified as key risk factors for complications within 30 days post-surgery.
Background: Recent reports on the influence of gender on the outcomes of total joint arthroplasty were limited by either lack of longitudinal data or absent stratification by total hip arthroplasty (THA) or total knee arthroplasty (TKA). As a result, there remains a lack of clarity on this topic.
Methods: The American College of Surgeons National Surgical Quality Improvement Program was queried for all primary, elective THAs and TKAs performed between 2011 and 2017.
We report the fabrication and characterization of metal-insulator-metal diodes incorporating vertically aligned carbon nanotube (VACNT) arrays encased in polymer for applications in high frequency optoelectronics. Polydimethylsiloxane (PDMS) and epoxy infiltrating media are used in this study. VACNT forests are embedded with polymer to form a planarized surface over which an array of tunneling diodes is fabricated.

Methods: Patients who had undergone a Huber opposition transfer with at least 5 years of follow-up were included in this study. There were 21 thumbs included; 12 returned for a detailed evaluation and 9 were included with a medical record review.
Background: The objectives of this study are to explore factors that are associated with use of adjuvant chemotherapy and to evaluate its impact on overall survival in node-negative patients who undergo lung and chest wall resection for non-small cell lung cancer (NSCLC).
Methods: Patients who underwent concomitant lung and chest wall resection for NSCLC were abstracted from the National Cancer Database. Clinical, pathologic, treatment, and follow-up data were obtained.
Background: Patients with advanced heart failure (HF) are predisposed to ventricular arrhythmias (VAs), particularly following implantation of a left ventricular assist device (LVAD). There is minimal evidence for appropriate management strategies.
Objectives: This study aimed to compare the burden of VA and response to ablation performed either before or following LVAD implantation.
Background: Adjuvant chemotherapy improves survival in patients with completely resected stage II and III NSCLC. However, its role in patients with stage IB NSCLC disease remains unclear. We evaluated the role of adjuvant chemotherapy in a large data set of patients with completely resected T2N0M0 NSCLC.

It is unclear how these recommendations are applied nationally, however.
Methods: The National Cancer Database was queried to identify patients with a tumor <7 cm (T1/T2) with clinically positive N1 nodes.
Purpose: To investigate the outcomes following surgical management of unstable and stable ulnar nerves at the elbow in young patients.
Methods: We retrospectively reviewed the charts of 67 patients who were 30 years old or younger when they underwent primary cubital tunnel surgery at our institution over a 10-year period. In 34 (45%) of these patients, the ulnar nerve either subluxated or perched on the medial epicondyle with elbow flexion and made up the "unstable" cohort.
Background: The role of pneumonectomy after neoadjuvant therapy for stage IIIA non-small cell lung cancer (NSCLC) remains uncertain.
Methods: Patients who underwent pneumonectomy for clinical stage IIIA NSCLC were abstracted from the National Cancer Database. Individuals treated with neoadjuvant therapy, followed by resection, were compared with those who underwent resection, followed by adjuvant therapy.
Unexpected readmission after lung cancer surgery: A benign event?

Objective: The study objective was to study the incidence, predictors, and implications of unanticipated early postoperative readmission after lung resection for non-small cell lung cancer.
Methods: Patients undergoing surgery for clinical stage I to III non-small cell lung cancer were abstracted from the National Cancer Database. Regression models were fitted to identify predictors of 30-day readmission and to study the association of unplanned readmission with 30-day and long-term survival.
Introduction: The relative roles of surgery and stereotactic body radiation therapy in stage I non-small-cell lung cancer (NSCLC) are evolving particularly for marginally operable patients. Because there is limited prospective comparative data for these treatment modalities, we evaluated their relative use and outcomes at the population level using a national database.
Methods: Patient variables and treatment-related outcomes were abstracted for patients with clinical stage I NSCLC from the National Cancer Database.
Background: This study evaluated the cost-effectiveness of combination chemotherapy, radiotherapy, and surgical intervention (CRS) vs definitive chemotherapy and radiotherapy (CR) in clinical stage IIIA non-small cell lung cancer (NSCLC) patients at academic and nonacademic centers.
Methods: Patients with clinical stage IIIA NSCLC receiving CR or CRS from 1998 to 2010 were identified in the National Cancer Data Base. Propensity score matching on patient, tumor, and treatment characteristics was performed.
Background: A substantial proportion of patients with clinical stage I non-small cell lung cancer (NSCLC) have more advanced disease on final pathologic review. We studied potentially modifiable factors that may predict pathologic upstaging.
Methods: Data of patients with clinical stage I NSCLC undergoing resection were obtained from the National Cancer Database.
Background: Improved survival of patients with early-stage non-small cell lung cancer (NSCLC) undergoing resection at high-volume centers has been reported. However, the effect of institution is unclear in stage IIIA NSCLC, where a variety of neoadjuvant and adjuvant therapies are used.
Methods: Treatment and outcomes data of clinical stage IIIA NSCLC patients undergoing resection as part of multimodality therapy was obtained from the National Cancer Database.
Background: The role of multimodality therapy in stage IIIB non-small cell lung cancer (NSCLC) remains inadequately studied. Although chemoradiation is currently the mainstay of treatment, randomized trials evaluating surgical intervention are lacking, and resection is offered selectively.
Methods: Data from patients with clinical stage IIIB NSCLC (T4N2 or any N3) undergoing definitive multimodality therapy were obtained from the National Cancer Database (NCDB).
Background: Conflicting evidence currently exists regarding the causes and effects of delay of care in non-small cell lung cancer (NSCLC). We hypothesized that delayed surgery in early-stage NSCLC is associated with worse short-term and long-term outcomes.
Methods: Treatment data of clinical stage I NSCLC patients undergoing surgical resection were obtained from the National Cancer Data Base (NCDB).
Purpose: To investigate the impact of modern postoperative radiotherapy (PORT) on overall survival (OS) for patients with N2 non-small-cell lung cancer (NSCLC) treated nationally with surgery and adjuvant chemotherapy.
Patients And Methods: Patients with pathologic N2 NSCLC who underwent complete resection and adjuvant chemotherapy from 2006 to 2010 were identified from the National Cancer Data Base and stratified by use of PORT (≥ 45 Gy). A total of 4,483 patients were identified (PORT, n = 1,850; no PORT, n = 2,633).
Objective: To study causes and implications of intraoperative conversion to thoracotomy during video-assisted thoracoscopic surgery (VATS) lobectomy.
Methods: We performed an institutional review of patients undergoing lobectomy for known or suspected lung cancer with root cause analysis of every conversion from VATS to open thoracotomy.
Results: Between 2004 and 2012, 1227 patients underwent lobectomy.
Introduction: The role of surgery in addition to chemotherapy and radiation for stage IIIA non-small-cell lung cancer (NSCLC) remains controversial. Because there are limited data on the benefit from surgery in this setting, we evaluated the use of combined modality therapy nationally and explored the outcomes with and without the addition of surgery.
Methods: Patient variables and treatment-related outcomes were abstracted for patients with clinical stage IIIA NSCLC from the National Cancer Database.
Background: Studies of endovascular renal denervation (RDN) have demonstrated significant blood pressure reduction in eligible patients with resistant hypertension. These trials have used stringent inclusion and exclusion criteria in patient enrollment, potentially selecting for a small subset of patients with resistant hypertension. In this study, we examined the changes in estimated prevalence of resistant hypertension when using increasingly stringent definitions of resistant hypertension in a fixed population and assessed the generalizability of RDN when applying study criteria to a community-based hypertensive population.
