Complications, Costs, and Health Care Resource Use with Tissue Biopsy Followed by Liquid Biopsy Versus Tissue Re-biopsy in Patients With Newly Diagnosed Metastatic Nonsmall-cell Lung Cancer.

Objectives: We compared complications, costs, and health care resource utilization (HCRU) of patients with newly diagnosed metastatic nonsmall-cell lung cancer (mNSCLC) who had a tissue biopsy followed by either liquid biopsy (TFLB) (identified with a novel algorithm) or tissue re-biopsy (TRB).

Methods: This claims-based retrospective analysis included commercial and Medicare Advantage members in the Optum Research Database with mNSCLC (January 2017 to June 2021) and ≥2 tissue biopsy claims (7 to 90 d apart) (TRB) or ≥1 tissue and ≥1 liquid biopsy claim within 90 days (TFLB). Patients in the TFLB group were matched 1:1 to patients in the TRB group using propensity score matching.

Economic burden of early-stage non-small-cell lung cancer: an assessment of healthcare resource utilization and medical costs.

To quantify the economic burden of early-stage non-small-cell lung cancer (NSCLC) among patients with and without adjuvant therapy. All-cause and NSCLC-related healthcare resource utilization and medical costs were assessed among patients with resected stage IB-IIIA NSCLC in the SEER-Medicare database (1 January 2011-31 December 2019), from NSCLC diagnosis to death, end of continuous enrollment, or end of data availability (whichever occurred first). Patients receiving adjuvant therapy had the lowest mean NSCLC-related medical costs (adjuvant [n = 1776]: $3738; neoadjuvant [n = 56]: $5793; both [n = 47]: $4818; surgery alone [n = 3478]: $4892, per-person-per-month), driven by lower NSCLC-related hospitalization rates.

Real-world study of disease-free survival & patient characteristics associated with disease-free survival in early-stage non-small cell lung cancer: A retrospective observational study.

Introduction/ Background: Surgical resection remains standard of care for patients with early-stage non-small cell lung cancer (NSCLC), but research shows that adjuvant therapy can reduce the risk of disease recurrence. Our objective was to characterize disease-free survival (DFS) using real-world data.

Materials And Methods: This was a retrospective study using the COTA real-world database derived from electronic health records in the United States (US).

Real-world outcomes among patients with EGFR-mutated non-small cell lung cancer treated with EGFR tyrosine kinase inhibitors versus immunotherapy or chemotherapy in the first-line setting.

Background: Despite national guideline recommendations, epidermal growth factor receptor mutated (EGFRm) metastatic non-small cell lung cancer (mNSCLC) patients may still receive suboptimal treatment in the first line (1L). This study evaluated 1L therapy initiation in relation to biomarker testing results and time to next-treatment or death (TTNTD) in patients receiving EGFR tyrosine kinase inhibitors (TKIs) versus immunotherapy (IO) or chemotherapy.

Methods: Stage IV EGFRm mNSCLC adults that initiated 1L EGFR TKI (first, second, or third generation), IO ± chemotherapy (IO users), or chemotherapy alone from 5/2017-12/2019 were identified from the Flatiron database.

Identification of Breed Differences in Known and New Fescue Toxicosis Associated Phenotypes in Charolais-and Hereford-Sired Crossbred Beef Cows.

Beef cattle phenotypes are affected by the consumption of toxic fescue. Toxic fescue's impact is dependent on heat stress and breed composition, with genetic variability for robustness to toxin exposure believed to exist within and across breeds. The study objective was to characterize the effect of fescue toxicosis across breeds for known and novel heat and fescue stress-associated phenotypes.

Effects of two dietary crude protein levels on finishing performance, meat quality, and gene expression of market lambs.

Seventeen crossbred lambs were assigned randomly to low-protein (LP; 8% crude protein [CP]; n = 9) and high-protein (HP; 13% CP; n = 8) diets for 9 weeks. The final body weight, average daily feed intake (ADFI), and average daily gain (ADG) of the HP lambs were significantly higher (P < 0.05) than the LP lambs; however, gain to feed ratio (G:F) for the LP lambs was significantly higher (P < 0.

Comparison of Growth Performance and Meat Quality Traits of Commercial Cross-Bred Pigs versus the Large Black Pig Breed.

The meat quality of different pig breeds is associated with their different muscle tissue physiological processes, which involves a large variety of genes related with muscle fat and energy metabolism. Understanding the differences of biological processes of muscle after slaughter is helpful to reveal the meat quality development of different breeds. Therefore, eight native Large Black pigs (BP), with high fat content in meat, and seven cross-bred commercial pigs (CP), which had a high feed efficiency with high lean meat, were used to investigate the differences in their meat quality and RNA transcriptomes.

Total ecosystem carbon stocks at the marine-terrestrial interface: Blue carbon of the Pacific Northwest Coast, United States.

The coastal ecosystems of temperate North America provide a variety of ecosystem services including high rates of carbon sequestration. Yet, little data exist for the carbon stocks of major tidal wetland types in the Pacific Northwest, United States. We quantified the total ecosystem carbon stocks (TECS) in seagrass, emergent marshes, and forested tidal wetlands, occurring along increasing elevation and decreasing salinity gradients.

Research Note: Dietary phytase reduces broiler woody breast severity via potential modulation of breast muscle fatty acid profiles.

Woody breast (WB) myopathy is a major concern and economic burden to the poultry industry, and for which, there is no effective solution because of its unknown etiology. In a previous study, we have shown that phytase (Quantum Blue, QB) reduces the WB severity by 5% via modulation of oxygen homeostasis-related pathways. As WB has been suggested to be associated with lipid dysmetabolism, we aimed to determine the effect of QB on WB and breast muscle fatty acid profile.

Treatment of Carotid Restenosis Using Transcarotid Revascularization.

Objective: Transcarotid artery revascularization (TCAR) using the ENROUTE Neuroprotection System (Silk Road Medical) is a United States Food and Drug Administration-approved treatment modality for stroke risk reduction in the setting of carotid artery stenosis. The goal of this investigation was to define the real-world outcomes associated with the application of this technique to patients presenting with restenosis after previous carotid endarterectomy (CEA) or transfemoral carotid artery stenting (TF-CAS).

Methods: Retrospective review of prospectively maintained institutional databases capturing all nontrial TCARs performed between August 2013 and July 2018 using the ENROUTE Neuroprotection System was completed at 3 unaffiliated hospital systems and unified for descriptive outcomes analysis.

Duration of blood flow reversal during transcarotid artery revascularization does not affect outcome.

Objective: Transcarotid artery revascularization (TCAR) has become an increasingly popular alternative for the treatment of carotid bifurcation stenosis. TCAR employs carotid blood flow reversal through an ex vivo common carotid artery to femoral vein shunt for neuroprotection during the placement and angioplasty of the carotid artery stent. There is a lack of data regarding an association between the duration of flow reversal and neurologic complications or other adverse events.

Microglial VPS35 deficiency regulates microglial polarization and decreases ischemic stroke-induced damage in the cortex.

Background: Vacuolar sorting protein 35 (VPS35), a critical component of retromer, is essential for selective endosome-to-Golgi retrieval of membrane proteins. It is highly expressed in microglial cells, in addition to neurons. We have previously demonstrated microglial VPS35's functions in preventing hippocampal, but not cortical, microglial activation, and in promoting adult hippocampal neurogenesis.

Longitudinal investigation of the swine gut microbiome from birth to market reveals stage and growth performance associated bacteria.

Background: Despite recent advances in the understanding of the swine gut microbiome at different growth stages, a comprehensive longitudinal study of the lifetime (birth to market) dynamics of the swine gut microbiome is lacking.

Results: To fill in this gap of knowledge, we repeatedly collected a total of 273 rectal swabs from 18 pigs during lactation (day (d) 0, 11, 20), nursery (d 27, 33, 41, 50, 61), growing (d 76, 90, 104, 116), and finishing (d 130, 146, 159, 174) stages. DNA was extracted and subjected to sequencing with an Illumina Miseq sequencer targeting the V4 region of the 16S rRNA gene.

The learning curve of transcarotid artery revascularization.

Background: In the pivotal U.S. Food and Drug Administration approval trial, ROADSTER, transcarotid artery revascularization (TCAR) using the ENROUTE Transcarotid Neuroprotection System (Silk Road Medical Inc, Sunnyvale, Calif) was shown to have one of the lowest reported complication rates, not only for carotid artery stent placement, but also for any carotid intervention, including endarterectomy.

A multi-institutional analysis of transcarotid artery revascularization compared to carotid endarterectomy.

Objective: Transcarotid artery revascularization (TCAR) is a novel approach to carotid intervention that uses a direct carotid cut-down approach coupled with cerebral blood flow reversal to minimize embolic potential. The initial positive data with TCAR indicates that it may be an attractive alternative to trans-femoral carotid artery stenting and possibly carotid endarterectomy (CEA) for high-risk patients. The purpose of this study was to present 30-day and 1-year outcomes after treatment by TCAR and to compare these outcomes against a matched control group undergoing CEA at the same institutions.
