Routine mutation profiling for resected lung cancers is not widespread despite an increasing array of targeted therapies. We report the incidence of EGFR mutations (EGFRmu+) in resected lung adenocarcinomas and their outcomes at a large, North American cancer center to characterize this population now eligible for targeted adjuvant therapy.

Among 1036 pulmonary resections performed between 2015-2019, 647 (62%) patients had adenocarcinomas that underwent molecular profiling by next-generation sequencing. Clinical and pathologic characteristics, along with survival, were analyzed.

EGFRmu+ were identified in 238 (37%) patients. Patients with EGFRmu+ were more likely to be Asian than those with EGFR wild-type (79/238 (33%) vs. 37/409 (9%), p<0.001) and more likely to be never-smokers (115/238 (48%) vs. 73/409 (18%), p<0.001). However, the majority of patients with EGFRmu+ in our cohort were white (45%) and had a history of smoking (52%). FDA approved Drug Library datasheet There was a statistically non-significant trend towards improvede approach to mutation profiling. Patients with surgically resected stage IA and IB lung adenocarcinomas enjoy excellent survival regardless of their mutational status.

The objective of this study was to identify trainee knowledge gaps in reimbursement and compensation, determine the perceived importance of understanding these topics, and to explore if the Thoracic Surgery Curriculum needs additional educational material.

The Thoracic Surgical Residents Association (TSRA) Executive committee selected the research proposal and distributed an anonymous electronic survey to 531 ACGME cardiothoracic surgery trainees. Standard descriptive statistics and regression analyses were performed.

114 responses were collected (response rate 21.5%). Most trainees understand little or not at all about how attending surgeons are reimbursed (n=74, 69%). Most trainees reported knowing little or nothing about pay-for-performance compensation (n=73, 67%), bundled care (n=82, 75%) or value-based reimbursement (n=84, 77%). Only approximately 20% of trainees were accurate in estimating surgeon reimbursement for three common cardiothoracic surgery procedures to within 20% of the true reimburseor trainees nationwide.

This study aimed to examine same-day associations of pain, fatigue, depressed mood, anxiety, and perceived cognitive function with social participation in the daily lives of adults with spinal cord injury (SCI).

Observational study utilized a combination of baseline surveys and 7 end-of-day (EOD) diaries.

General community.

Individuals with SCI (N = 168; mean age= 49.8 years; 63% male, 37% female).

Patient Reported Outcomes Measurement Information System (PROMIS) short form measures (Ability to Participate in Social Roles and Activities, Pain Intensity, Depression, Anxiety, and Cognitive Function Abilities) were adapted for daily administrations as EOD diaries.

Results of multilevel modeling showed that daily increases in fatigue (B= -0.10; p=0.004) and depressive symptoms (B= -0.25; p=.<0.001), and decreases in perceived cognitive function (B= 0.11; p=.<0.001) were significantly related to worse same-day social participation. Daily fluctuations in anxiety and pain were unrelated to same-day social participation.

This is the first study that shows within-person associations of common SCI symptoms with social participation in the daily lives of adults with SCI. Results from the current study may help to develop more effective individualized treatments of symptoms and symptom impact aimed at improving social participation.

Although patients' clinical conditions have been shown to be associated with coronavirus disease (COVID-19) severity and outcome, their impact on hospital costs are not known. This economic evaluation of COVID-19 admissions aimed to assess direct and fixed hospital costs and describe their particularities in different clinical and demographic conditions and outcomes in the largest public hospital in Latin America, located in São Paulo, Brazil, where a whole institute was exclusively dedicated to COVID-19 patients in response to the pandemic.

This is a partial economic evaluation performed from the hospital´s perspective and is a prospective, observational cohort study to assess hospitalization costs of suspected and confirmed COVID-19 patients admitted between March 30 and June 30, 2020, to Hospital das Clínicas of the University of São Paulo Medical School (HCFMUSP) and followed until discharge, death, or external transfer. Micro- and macro-costing methodologies were used to describe and analyze the totaomprehensive approach for decision-making and planning for future risk management.

Exercise, as a common non-drug intervention, is one of several lifestyle choices known to reduce the risk of cancer. Mitochondrial division has been reported to play a key role in the occurrence and transformation of hepatocellular carcinoma (HCC). This study investigated whether exercise could regulate the occurrence and development of HCC through mitosis.

Bioinformatics technology was used to analyze the expression level of dynamin-related protein 1 (DRP1), a key protein of mitochondrial division. The effects of DRP1 and DRP1 inhibitor (mdivi-1) on the proliferation and migration of liver cancer cells BEL-7402 were observed using cell counting kit-8, plate colony formation, transwell cell migration, and scratch experiments. Enzyme-linked immunosorbent assay, Western blot and real-time polymerase chain reaction were used to detect the expression of DRP1 and its downstream phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) pathway. A treadmill exercise intervention was tested in a nude mouse human li exercise can suppress the development of tumors partially by regulating DRP1 through PI3K/AKT pathway.

To determine the therapeutic effectiveness and safety of transarterial radioembolization (TARE) with Yttrium-90 in patients with colorectal cancer (CRC) liver metastases and to evaluate the prognostic value of different biomarkers.

This prospective longitudinal study enrolled consecutive patients with CRC liver metastases treated with TARE between November 2015 and june 2020. The therapeutic response at three and six months (RECIST1.1 criteria) and the relationship of biomarkers with therapeutic response, by calculating objective tumor response rates (ORR) and disease control (DCR), and overall survival (OS) and progression-free (PFS).

Thirty TAREs were performed in 23 patients (mean age, 61.61 ± 9.13 years; 56.5% male). At three months, the objective response rate (ORR) was 16.7% and the disease control rate (DCR) 53.3%. At six months, the disease progressed in 80%. The ORR and DCR were significantly associated with age at diagnosis (P = 0.047), previous bevacizumab treatment (P = 0.008), pre-TARE haemoglobin (P = 0.008), NLR (P = 0.040), pre-TARE albumin (P = 0.012), pre-TARE ALT (P = 0.023) and tumour-absorbed dose > 115 Gy (P = 0.033). Median overall survival (OS) was 12 months (95% CI, 4.75-19.25 months) and median progression-free survival (PFS) 3 months (95% CI, 2.41-3.59). OS was significantly associated with primary tumour resection (P = 0.019), KRAS mutation (HR 5.15; P = 0.024), pre-TARE haemoglobin (HR 0.50; p = 0.009), pre-TARE NLR (HR 1.65; P = 0.005) and PLR (HR 1.01; P = 0.042).

TARE prognosis and therapeutic response were predicted by different biomarkers, ranging from biochemical parameters to tumour dosimetrics.

This study sought to describe trends in cardiovascular implantable electronic device (CIED) insertion over the past 3 decades in Olmsted County.

Trends in CIED insertion in the United States have not been extensively studied.

The Rochester Epidemiology Project is a medical records linkage system comprising the records of all residents of Olmsted County from 1966 to the present. CIED insertion between 1988 and 2018 was determined using International Classification of Diseases-Ninth Revision, International Classification of Diseases-10th Revision, and Current Procedural Terminology codes. Age- and sex-adjusted incidence rates, adjusted to the 2010 US White population, were calculated. Trends in incidence over time, across age groups, and between sex are estimated using Poisson regression models.

The age- and sex-adjusted incidence of device implants for the study period were as follows overall CIED 82.4 (95%CI 79.2-85.6); permanent pacemaker (PPM) 62.9 (95%CI 60.0-65.7); implantable cardioverter-defibriy, men, and patients with higher comorbidities.

This study describes the clinical and electrophysiological characteristics of basal-septal ventricular tachycardias (VTs) in patients with structural heart disease (SHD).

The basal septum is a common source of VT in patients with SHD.

Data from 312 consecutive patients with SHD undergoing catheter ablation of ventricular arrhythmias were reviewed.

Thirty-three basal-septal VTs in 31 patients (mean age 67.4 ± 14.2 years, mean left ventricular ejection fraction [LVEF] 42% ± 15%) were identified. Patients with VTs with left ventricular basal-septal breakthrough were more likely to have ischemic cardiomyopathy and lower LVEF; patients with right ventricular basal-septal VT were more likely to have sarcoidosis or right ventricular cardiomyopathy of unknown significance, with higher LVEF. Atrioventricular block was present in 45% of patients and intraventricular block including persistent biventricular pacing in 77%. Unipolar scar was larger than bipolar scar (area 18.8% ± 19.4% vs 12.7% ± 14.6%; P< 0.00 intramural septal substrate that limits procedural success after catheter ablation.

This study aimed to compare the efficacy and safety of ablation with high and low power settings using either a flexible tip or straight SF tip irrigated catheter in the left ventricle (LV) using a peripheral microemboli monitoring system.

The microemboli risk of flexible and straight SF tip irrigated catheters in creating ablative lesions in the LV at variable power settings has not been adequately assessed.

Six pigs underwent catheter ablation in the LV using a flexible tip or straight SF tip catheter with 2 energy settings (30 or 50 W, 30 seconds, irrigation saline 17mL/min).

A total of 79 radiofrequency (RF) applications were assessed. High power settings via a flexible tip formed a significantly higher arterial microbubble volume in the extracorporeal circulation (P = 0.005). Notably, RF applications with a steam pop induced an exponential increase of microbubble volume with both catheters. A higher power setting induced a significantly higher number of microembolic signals on carotid artery Doppler ultrasound with a flexible tip irrigated catheter (P< 0.
