Disparate Access to Surgery for Operable Carcinoma of the Lung in North Carolina.

PURPOSE: Disparities in access to surgical care are associated with poorer outcomes in patients with cancer. We sought to determine whether vulnerable populations undergo an expected rate of surgery for Stage I-IIIA lung cancer in North Carolina (NC). METHODS: We calculated the proportional surgical ratio (PSR) to identify a potential disparity in surgery rates for early stage (I-IIIA) lung cancer, first in the five counties with the worst health outcomes (LRC) and subsequently the entire state. The reference was the five healthiest counties (HRC), initially, and then the single county with the best health outcomes. RESULTS: In 2016, 3,452 individuals with Stage I-IIIA lung cancer were diagnosed in NC of which 246,854 resided in LRC, whereas 1,865,588 resided in HRC. A total of 453 operable lung cancers were diagnosed in the HRC and 107 in the LRC. The observed lobectomy rate in HRC was 40.1% (range 20.2-58.3%) of early-stage lung cancer and 19% (range 12-36%) for LRC. The PSR was 0.65 (95% confidence interval [CI] = 0.35, 0.90). For all 99 counties across NC, the PSR ranged from 0.33 to 0.96 (mean = 0.49, standard deviation [SD] = 0.10). In a multivariable model, only other primary care provider ratio (relative rate per 100 increase = 0.997; 95% CI = 0.994, 0.999) was significantly associated with PSR. CONCLUSIONS: Individuals residing in LRC in NC are 42% less likely to undergo surgery for operable lung cancer than patients living in HRC. Understanding how factors impact access is key to designing informed interventions.

Lung Cancer: Epidemiology and Screening.

Lung Cancer remains the leading cause of cancer mortality in the United States and Worldwide. Incidence and mortality have been on the decline in the United States, while worldwide cases continue to increase. Risk factor modification and screening are critical to improving survival in patients with lung cancer. Identifying at-risk populations for access to care and screening programs will improve overall outcomes. Understanding environmental and carcinogenic sources are integral to public health policy and education. Innovations in population health and translational research will be essential in the future to improve lung cancer survival.

Multimodal Pain Management Protocol to Decrease Opioid Use and to Improve Pain Control After Thoracic Surgery.

BACKGROUND: Opioid addiction continues to be a devastating problem in our communities, and up to 40% of patients begin their addiction with legally prescribed opioids after injury or surgical procedure. An opioid-free multimodal pain regimen was developed with the goal of decreasing opioid exposure while maintaining adequate pain control. METHODS: A retrospective single-institution study was conducted of 313 consecutive patients undergoing minimally invasive lobectomy before (n = 211) and after (n = 102) implementation of an opioid-free protocol from 2016 to 2020. Data analysis was conducted on preoperative characteristics, postoperative opioid use at set time points (postoperative day 0, postoperative days 1 to 7, and total stay), pain scores, discharge with opioid prescription, and postoperative outcomes. RESULTS: Patients on the opioid-free protocol had significantly lower average total morphine milligram equivalents at all time points. In addition, 56% of patients in the opioid-free group received no oral opioids at all, and 91% did not receive a patient-controlled analgesia pump. Average pain scores were significantly lower in the opioid-free protocol patients along with percentage of time spent with pain scores <3 and <6. With implementation of the protocol, 62% of patients are discharged without an opioid prescription compared with only 7% previously. CONCLUSIONS: Implementation of an opioid-free protocol led to a significant decrease in the use of postoperative opioids at all time points while improving overall management of pain. In addition, most patients are discharged with no home opioid prescription, decreasing a potential source of community opioid spread.

Tracheal Transection From Gunshot Wound to the Neck.

A male patient presented with a gunshot wound superior to his left scapula and difficulty breathing. En route to the emergency department, he rapidly became unresponsive, culminating in a cricothyroidotomy by paramedics. Oxygen saturation was 70% on arrival, and a tracheobronchial injury was suspected. In the operating room, a complete transection of the mid trachea was found and repaired. Postoperatively, the patient had acute respiratory distress syndrome. He was placed on extracorporeal membrane oxygenation and was eventually decannulated on postoperative day 12. The need for immediate identification of airway inadequacy, despite appropriate interventions, is underscored by this case report.

Are Esophagectomy Board Requirements Achievable? A Multi-Institutional Analysis.

Duty-hour restrictions have implications on trainee operative exposure necessary to meet minimum case-volume requirements. We utilized a previously validated simulation model to evaluate the effect of program volume, trainee numbers and complement, and rotation schedule on the probability of achieving adequate esophagectomy case numbers for cardiothoracic surgery trainees. A ProModel simulator centered on probabilistic distributions of operative cases was utilized. Historical data from five 2-year cardiothoracic surgery training programs were obtained from 2016-2018 and used as inputs to the simulator that generated 10,000 "trainee 2-year periods" per program. Programs varied in annual average esophagectomy volume (12-91 per year), with 2-4 trainees graduating over a 2-year training period. If esophagectomy cases were distributed solely based on scheduling and institutional volume, only 60% of evaluated programs could adequately expose all trainees in esophagectomy to meet case requirements. The 3 programs with adequate esophagectomy volumes had averaged 3.3 times (range 3.0-3.6) the minimum number of board-required cases for their programs' trainees. The ability of programs to provide trainees with adequate esophagectomy volume is challenging based on institutional volume and scheduling. Through simulation, we demonstrate that programs need >2 times the expected minimum number of esophagectomies to ensure that >90% of trainees meet case-volume requirements. Programs may consider strategies such as allowing trainees to select cases based on personal need, train fewer fellows, or enable trainees to seek subspecialty exposure externally to achieve minimum esophagectomy case-load requirements.

Establishment of a per oral endoscopic myotomy program at a rural tertiary care center.

BACKGROUND: This study's purpose is to determine the application and effectiveness of a POEM program in the rural healthcare setting. Achalasia has a substantial impact on the lives of afflicted patients. Traditionally, a Heller myotomy with fundoplication has been the standard of care for treatment. In 2008, the first per oral endoscopic myotomy (POEM) was performed in Japan. Since 2017, our rural healthcare institution has performed approximately 60 POEMs. METHODS: An IRB approved, single-institution retrospective review of patient outcomes after POEM was performed along with prospective analysis of post-operative surveys. An institutional cost analysis was also performed. Demographic and qualitative variables were measured and included PPI use, a Likert scale of 0-5 for progressively worsening symptoms of heartburn, dysphagia, and regurgitation. In addition, we included a Dysphagia Outcome and Severity Scale. RESULTS: The number of myotomy operations increased from 4.5 per year to 28.8 per year after initiation of the POEM program. Mean Likert scale scores were 0.91, 0.73, and 1 for heartburn, dysphagia, and regurgitation, respectively. 72.5% percent of patients were satisfied with their present condition. 87.5% of patients reported minimal or no dysphagia on the Dysphagia Severity Scale. Intraoperative costs were $2477 for laparoscopic myotomy and $1650 for POEM. The capital expense of the equipment required to perform POEM was $110,232. Average contribution margin per case was $6024. The procedure pays off capital outlay upon completion of the 19th case. CONCLUSIONS: This study shows that patients have excellent symptom control after POEM. When compared to the institution's laparoscopic myotomy volume, POEM far surpasses in terms of operative volume and monetary benefit. Examination of these data shows that a rural hospital can successfully employ a state-of-the-art intervention when there is a population in need and an infrastructure in place.

Fundic gastropexy for high risk of recurrence laparoscopic hiatal hernia repair and esophageal sphincter augmentation (LINX) improves outcomes without altering perioperative course.

BACKGROUND: The aim of this study is to show that the addition of a fundic gastropexy to a laparoscopic hiatal hernia repair (HHR) and magnetic sphincter augmentation (MSA) with LINX (Johnson and Johnson, New Brunswick, NJ) in patients with high risk for hiatal hernia recurrence improves outcomes without altering perioperative course. METHODS: An IRB approved, single institution retrospective review of patient outcomes after hiatal hernia repair with magnetic sphincter augmentation was performed. Data were obtained from the electronic health record and stored in a REDCap database. Using statistical software, the patient data were analyzed and stratified to assess the specific variables of the perioperative and postoperative course focusing on the high risk of hiatal hernia recurrence group (HRHR) and low risk hiatal hernia of recurrence group (LRHR). The HRHR group received a gastropexy and were defined using the following variables: comorbid state increasing abdominal pressure, gastric herniation > 30%, maximum transverse crural diameter > 4 cm, age 70 years or older, previous hiatal or abdominal wall hernia repair, BMI > 34, heavy weight bearing job/hobby, and/or emergent repair. RESULTS: Hiatal hernia repair with magnetic sphincter augmentation was performed on 137 patients. The HRHR group (N = 86) and the LRHR group (N = 51) were compared and there was a difference observed with acute hernia recurrence, dysphagia (p value = 0.008), and number of post-op EGDs (p value = 0.005) in favor of the HRHR group. Other postoperative variables observed (i.e., length of stay and PPI use) showed no significant difference between the two groups. CONCLUSIONS: Fundic gastropexy for individuals who are considered high risk for recurrence does not appear to alter the perioperative course in our sample of patients. The HRHR group has the same length of stay experience and improved postoperative outcomes with reference to postoperative EGD, dysphagia and a decreasing trend in hiatal hernia recurrence.

Robotic-Assisted Thoracoscopic Repair of Right-Sided Bochdalek Hernia in Adults: A Two-Case Series.

Bochdalek hernia is a congenital diaphragmatic hernia that presents rarely in adulthood. Because of the paucity of cases, no standard repair technique has been identified. Here we present two cases of robotic, thoracoscopic repair of this rare hernia defect. Two separate adult patients with right-sided abdominal pain presented to the emergency department for evaluation. Both patients were diagnosed with right-sided Bochdalek hernia and repair was undertaken with a robotic, transthoracic approach. Repair technique is described in detail, including port placement, dissection technique, and repair strategy. Advantages of the robotic, transthoracic approach are discussed in detail. A transthoracic minimally invasive approach using a robotic platform is noted to be both feasible and practical in the treatment of adult Bochdalek hernia.

Measuring outcomes in oncology treatment: the importance of patient-centered outcomes.

An important component of quality healthcare is that it be patient-centered with a focus on the patient, including his or her preferences, values, and beliefs. The goal of this article is to provide a broad overview of patient-centered outcomes in oncologic research. It starts with an introduction to the different types of patient-centered measures including patient satisfaction, decision regret, patient preference, and health-related quality of life. It then offers an overview of survey instrument design and selection. Finally, it provides examples of existing approaches to measurement and previously validated instruments for each type of patient-centered outcome.

Transient activation of NF-kappaB through a TAK1/IKK kinase pathway by TGF-beta1 inhibits AP-1/SMAD signaling and apoptosis: implications in liver tumor formation.

NF-kappaB has been implicated in the regulation of apoptosis, a key mechanism of normal and malignant growth control. Previously, we demonstrated that inhibition of NF-kappaB activity by TGF-beta1 leads directly to induction of apoptosis of murine B-cell lymphomas and hepatocytes. Thus, we were surprised to determine that NF-kappaB is transiently activated in response to TGF-beta1 treatment. Here we elucidate the mechanism of TGF-beta1-mediated regulation of NF-kappaB and induction of apoptosis in epithelial cells. We report that TGF-beta1 activates IKK kinase, which mediates IkappaB-alpha phosphorylation. In turn, the activation of IKK following TGF-beta1 treatment is mediated by the TAK1 kinase. As a result of NF-kappaB activation, IkappaB-alpha mRNA and protein levels are increased leading to postrepression of NF-kappaB and induction of cell death. Inhibition of NF-kappaB following TGF-beta1 treatment increased AP-1 complex transcriptional activity through sustained c-Jun phosphorylation, thereby potentiating AP-1/SMADs-mediated cell killing. Furthermore, TGF-beta1-mediated upregulation of Smad7 appeared independent of NF-kappaB. In hepatocellular carcinomas of TGF-beta1 or TGF-alpha/c-myc transgenic mice, we observed constitutive activation of NF-kappaB that led to inhibition of JNK signaling. Overall, our data illustrate an autocrine mechanism based on the ability of IKK/NF-kappaB/IkappaB-alpha signaling to negatively regulate NF-kappaB levels thereby permitting TGF-beta1-induced apoptosis through AP-1 activity.
