AbstractIn this study, the corrosion behavior of N80 and TP125V steels was delved firstly into produced water from shale gas fields containing CO2-O2. Moreover, the localized corrosion of these steels was investigated to elucidate the effects of aerobic and anoxic on steel corrosion. The results indicated that the corrosion rates of N80 and TP125V steels under aerobic conditions were lower compared to those in the presence of CO2-O2. Specifically, at temperature of 100 °C and with dissolved oxygen (DO) concentration of 4 mg/L in the CO2-O2 environment, the N80 and TP125V steels exhibited the highest corrosion rate, with values of 0.13 mm/y and 0.16 mm/y, respectively, as determined by specific weight loss measurements. Conversely, these rates decreased to 0.022 mm/y and 0.049 mm/y under aerobic conditions. Furthermore, severe localized corrosion of N80 and TP125V steels with a DO concentration of 4 mg/L was also observed in the CO2-O2 environment. Finally, it was evident that pitting corrosion is the predominant type of corrosion affecting N80 and TP125V steels in the produced water from shale gas fields.

Abstract
Background
Hospital services are typically reimbursed using case-mix tools that group patients according to diagnoses and procedures. We recently developed a case-mix tool (i.e., the Queralt system) aimed at supporting clinicians in patient management. In this study, we compared the performance of a broadly used tool (i.e., the APR-DRG) with the Queralt system.

Methods
Retrospective analysis of all admissions occurred in any of the eight hospitals of the Catalan Institute of Health (i.e., approximately, 30% of all hospitalizations in Catalonia) during 2019. Costs were retrieved from a full cost accounting. Electronic health records were used to calculate the APR-DRG group and the Queralt index, and its different sub-indices for diagnoses (main diagnosis, comorbidities on admission, andcomplications occurred during hospital stay) and procedures (main and secondary procedures). The primary objective was the predictive capacity of the tools; we also investigated efficiency and within-group homogeneity.

Results
The analysis included 166,837 hospitalization episodes, with a mean cost of € 4,935 (median 2,616; interquartile range 1,011–5,543). The components of the Queralt system had higher efficiency (i.e., the percentage of costs and hospitalizations covered by increasing percentages of groups from each case-mix tool) and lower heterogeneity. The logistic model for predicting costs at pre-stablished thresholds (i.e., 80th, 90th, and 95th percentiles) showed better performance for the Queralt system, particularly when combining diagnoses and procedures (DP): the area under the receiver operating characteristics curve for the 80th, 90th, 95th cost percentiles were 0.904, 0.882, and 0.863 for the APR-DRG, and 0.958, 0.945, and 0.928 for the Queralt DP; the corresponding values of area under the precision-recall curve were 0.522, 0.604, and 0.699 for the APR-DRG, and 0.748, 0.7966, and 0.834 for the Queralt DP. Likewise, the linear model for predicting the actual cost fitted better in the case of the Queralt system.

Conclusions
The Queralt system, originally developed to predict hospital outcomes, has good performance and efficiency for predicting hospitalization costs.

Abstract
Background
Lichen planus (LP) is a chronic inflammatory disease with uncertain etiology. Interleukin-18 (IL-18) is an interferon gamma (INFγ) inducing agent. It is a pro-inflammatory cytokine that was found to play a role in the pathogenesis of some autoimmune disorders.

Material and methods
This study included 50 patients with classic cutaneous lichen planus (CLP) and 50 healthy volunteers serving as controls. Venous blood samples were withdrawn from the study subjects under complete aseptic precautions. Blood samples were examined for single nucleotide polymorphisms (SNPs) of IL-18 gene at promoter -137(G/C) and -656 (G/T) using polymerase chain reaction (PCR) and IL-18 level was assessed using enzyme linked immunosorbent assay (ELISA).

Results
The mean level of IL-18 was significantly higher in CLP patients (31.63 ± 4.90) compared to control subjects (13.95 ± 6.82). Significantly high levels of IL-18 were found among patients with diabetes, hypertension (p < 0.01 in both). HCV positive patients and patients with both OLP and CLP also expressed higher levels of IL-18. Genotypic and allelic distribution at position -137(G/C) showed that the genotype GG was present at significantly higher frequency in cases (58%) compared to controls (28.0%). On the other hand the CC genotype at position -137 was significantly higher in the controls (28%) as compared to CLP cases (6%). Polymorphism of IL-18 at position -656(G/T) showed no significant difference between cases and controls. No significant difference could be detected in IL-18 level between different genotypic variants at position -137(G/C) and -656(G/T).

Conclusion
IL-18 may play important role in pathogenesis of LP. Elevated IL-18 levels could be part of the pro-inflammatory autoimmune process in LP. The presence of OLP, HCV, diabetes and hypertension is associated with higher production of IL-18. IL-18 promotor region -137(G/C) polymorphism might be a factor that increase the risk of development of lichen planus in Egyptian patients.

Published: June 2024

AbstractTo gain a deeper understanding of the carbon emission mechanism from transportation facilities, all system elements affecting carbon emissions from regional transportation facilities are identified and analyzed according to panel data from 30 regions in China. A spatial econometric model for carbon emissions from transportation facilities is constructed using the Spatial Dolbin model from 2004 to 2022 as the research period. From the results, the carbon dioxide emissions from transportation facilities added from 318 million tons in 2004 to 752 million tons in 2022, with an average annual growth rate of 4.9%. The global spatial auto-correlation coefficient was significant at the 5%, with an obvious spatial correlation between carbon dioxide emissions within a geographical range. In addition, through stability testing, the model showed high stability in both spatial lag testing and spatial error testing, demonstrating strong ability to interpret data. The research shows that the carbon emission is affected by independent variables, including population, economy, technology, and transportation, and exhibit significant spatial distribution characteristics in different regions and years, providing a basis for policy formulation and carbon emission management.

Abstract
Objective
Cervical cancer (CxCa) stands as a significant global health challenge, ranking fourth in cancer-related mortality among the female population. While chemotherapy regimens have demonstrated incremental progress in extending overall survival, the outlook for recurrent CxCa patients remains disheartening. An imperative necessity arises to delve into innovative therapeutic avenues, with molecular targeted therapy emerging as a promising candidate. Previous investigations have shed light on the therapeutic effectiveness of five distinct herbal compounds, epicatechin, curcumin, myricetin, jatrorrhizine, and arborinine, within the context of CxCa.

Methods
A systems biology approach was employed to discern differentially expressed genes (DEGs) in CxCa tissues relative to healthy cervical epithelial tissues. A protein–protein interaction network (PPIN) was constructed, anchored in the genes related to CxCa. The central genes were discerned within the PPIN, and Kaplan–Meier survival curves explored their prognostic significance. An assessment of the binding affinity of the selected herbal compounds to the master regulator of prognostic markers in CxCa was conducted.

Results
A significant correlation between the overexpression of MYC, IL6, JUN, RRM2, and VEGFA and an adverse prognosis in CxCa was indicated. The regulation of these markers is notably influenced by the transcription factor CEBPD. Molecular docking analysis indicated that the binding affinity between myricetin and the CEBPD DNA binding site was robust.

Conclusion
The findings presented herein have unveiled pivotal genes and pathways that play a central role in the malignant transformation of CxCa. CEBPD has emerged as a potential target for harnessing the therapeutic potential of myricetin in this context.

6560 Background: The use of reduced intensity conditioning regimens including non-myeloablative regimens in allogeneic hematopoietic stem cell transplant (allo SCT), has expanded the pool of transplant candidates in the United States. Nonetheless, allo SCT, is associated with significant morbidity and mortality especially in patients 65 and older. In our outpatient transplant program, allo SCT patients undergo a comprehensive physical and occupational therapy (PT/OT) evaluation pre-transplant. Methods: We retrospectively reviewed all patients undergoing an allo SCT between January 2019 and December 2022 who had a PT/OT evaluation pre-transplant. We analyzed lower extremity functional scale (LEFS) and fatigue score (FACIT). The FACIT score is a patient reported outcome tool where the lower the score, the less fatigue impacts a patient’s performance. Results: We identified 218 patients who had at least one variable reported. Eighty-one patients were 65 years of age or older. All patients in the 65 and older group had a RIC or NMA conditioning regimen. In the 65 and older group, 72.8% had an HCTCI score of 3 or more compared to 59.1% in the group younger than 65. In patients younger than 65, those who had a lower LEFS (ie less lower extremity strength), had a statistically significant longer hospital stay of 15.5 days compared to 9 days (p=0.003). In patients 65 and older, lower FACIT scores (ie less patient reported fatigue), resulted in a statistically significant shorter hospital stay of 7.5 days compared to 13 days (p=0.019). In addition, there was a trend towards shorter hospital stays in patient 65 and older who had a higher LEFS of 5 days compared to 12.5 days (p=0.07). There was no difference in survival outcomes but there was a trend towards better overall survival in patients 65 and older with high LEFS (p=0.08) and a trend towards better NRM in this group (p=0.11). Conclusions: Our study highlights the need for comprehensive assessments in patients undergoing allo SCT. Geriatric functional status assessments are necessary to determine patients at risk for complications and to optimize such patients with exercise and cognitive rehabilitation programs prior to allo SCT.

Published: June 2024

6582 Background: Although high symptom burden indicates poor survival and informs treatment decisions, little is known about the impact of demographic, clinical, and laboratory features on total symptom score (TSS) in patients with myeloproliferative neoplasms (MPN). Methods: Patients with MPN (polycythemia vera (PV), essential thrombocythemia (ET), and myelofibrosis (MF)) were identified from the retrospective chart review. TSS, individual symptom scores (fatigue, early satiety, abdominal discomfort, inactivity, concentration problems, fever, night sweats, itching, bone pain, weight loss), demographic characteristics (race, ethnicity, age, gender), clinical features (time since diagnosis, depression status, obesity status, spleen size), laboratory results and season at the time of visit were recorded from the clinical encounter when index assessment of TSS was performed for each patient. Normality was assessed using visual inspection of data distribution, whereas multicollinearity was assessed using various inflation factors. A univariable regression followed by a multivariable regression analysis was conducted using a backward selection approach. A p-value <0.05 indicated a statistically significant association of a given feature with TSS. Results: The chart review identified 252 patients (PV: 78; ET: 81; MF: 93). Mean age was 59 (SD: 17.7), 67 (SD: 13.0), and 68 (SD: 10.9) years for ET, PV, and MF respectively. Most patients were white (PV, MF: 92%; ET: 83%) and females (ET: 75%; PV: 60%; MF: 53%). The TSS of patients was highest with PV (mean: 18.5; SD: 16.9) followed by MF (mean: 18.1; SD: 15.4) and ET (mean: 14.3; SD: 15.9). Fatigue was the most reported symptom whereas the least reported symptoms were fever and weight loss. Univariable regression analyses showed depression (B: 17.7; p=0.02), female gender (B: 10.6; p=0.01), platelet count (B: 0.03; p=0.03), and hemoglobin (Hb) (B: -2.6; p=0.01) in PV patients, depression (B: 19.8, p=2x10-5) in ET patients and depression (B: 11.0, p=0.03), white blood cell (WBC) count (B: 0.2; p=0.01), neutrophil count (B: 0.3, p=0.01), and non-neutrophil WBC count (B: 0.6; p=0.02) in MF patients to have significant association with TSS. Multivariable regression analyses ( Table) showed Hb (B: -2.5; p=0.01) and platelet count (B: 0.02; p=0.03) in PV patients, depression (B: 19.7; p=2x10-5) in ET patients and depression (B: 12.3, p=0.01) and WBC count (B: 0.3; p=0.002) in MF patients to have a significant association with TSS. Conclusions: Depression in ET and MF and low Hb in PV were identified as significant drivers of symptom burden. Identifying and managing patients with these comorbidities could improve their quality of life with a potential survival benefit. [Table: see text]

Authors: Qi Yana , Sun Yulan , Zhu Hui , Guo Hongbo 
Published: June 2024

8073 Background: Neoadjuvant chemoimmunotherapy has been successfully used in resectable non-small cell lung cancer (NSCLC) patients. However, its application in advanced stage unresectable NSCLC remains a topic of debate. This retrospective study was designed to evaluate the efficacy and safety of neoadjuvant chemoimmunotherapy followed by surgical resection in patients with initial unresectable stage III NSCLC, focusing on the surgical resection rate and the survival benefits of surgery. Methods: Patients unresectable stage III NSCLC who received 2-4 cycles of neoadjuvant chemoimmunotherapy between January 2021 and December 2022 were retrospectively identified. Data on characteristics, radiological and pathological responses, and survival outcomes were collected. Results: In total, 148 patients with unresectable stage III NSCLC were recruited. After the last cycle of neoadjuvant therapy, 105 (70.9%) patients were evaluated to be eligible for surgery, and 102 patients ultimately underwent surgery. The rate of complete (R0) resection was 100%, with a major pathological response (MPR) observed in 63.7% and a pathologic complete response (pCR) in 41.2%. Postoperative complications were observed in 9 patients (8.8%), and there was no surgical-related mortality within 30 days. With a median follow-up of 21.9 months, the median progression-free survival (PFS) was 19.6 months in the non-surgery group and not reached in the surgery group. The median overall survival (OS) was not reached in either group. Conclusions: The use of neoadjuvant chemoimmunotherapy is effective in converting unresectable stage III NSCLC into resectable NSCLC. Subsequent radical surgery is safe with low complications and surgical-related mortality.

8075 Background: Resectable Stage II and III Non-small Cell Lung Cancer (NSCLC) are managed with surgery and perioperative systemic therapy [Chemo/Chemo-Immunotherapy (IO)]. However, there lacks a consensus in optimal selection between neoadjuvant and adjuvant approaches. Hence, it underscores the necessity to undertake a comparative survival outcome associated with systemic therapy in these distinct settings. Methods: We conducted an analysis, of individuals aged 18 and above diagnosed with stage II and stage III NSCLC between 2004 - 2020, using data from the National Cancer Database (NCDB). Overall survival (OS) was compared for both Neoadjuvant and Adjuvant systemic therapy using Cox proportional hazards models after adjusting for sociodemographic (e.g., age, sex, race-ethnicity, and income) and health (e.g., insurance and facility type) related factors. The inclusion criteria involved restricting the analysis to individuals with no more than one lifetime cancer diagnosis and excluding those who received radiation therapy. Results: Among approximately 2 million total patients with NSCLC in NCDB, 8.38% and 20% were stage II and III respectively. After we identified a total of 137,473 eligible patients, 27,115 had relevant treatment information with 2,550 Neoadjuvant Chemo, 112 Neoadjuvant chemoIO, 24,175 Adjuvant chemo and 278 Adjuvant chemoIO. A statistically significant association between OS and treatment group was observed [χ2(3) =55.5, p<.001]. The OS was notably higher in the Neoadjuvant chemoIO group (78.57%) compared to Adjuvant chemoIO group (55.76%), whereas the Neoadjuvant chemo-only group exhibited lower OS (45.41%) compared to the Adjuvant chemo group (47.98%). The Cox proportional hazards model showed 70% higher mortality risk in the Adjuvant chemoIO group compared to the Neoadjuvant chemoIO group (p=0.030, 95% CI 1.05-2.77). The 2-year and 5-year OS rates for Neoadjuvant ChemoIO were 77.9% and 68.8%, respectively versus 68.7% and 42.8% for Adjuvant chemoIO group. Conclusions: Our analysis reveals that Neoadjuvant chemoIO demonstrates superior survival outcomes compared to Adjuvant chemoIO. Additionally, our findings suggest the potential predictive value of Immunotherapy in combination with chemotherapy in the Neoadjuvant setting. Key Words: NSCLC, Neoadjuvant treatment, Adjuvant treatment, Chemotherapy, Immunotherapy, OS.

8082 Background: Consolidation immunotherapy after chemoradiation is the standard of care for unresectable stage III NSCLC. Addition of immunotherapy-based induction treatment may further improve outcome, partly by enabling surgery. We conducted a proof-of-concept, phase 2 trial to assess neoadjuvant SHR-1701 (an anti-PD-L1/TGF-β bifunctional fusion protein) with or without chemotherapy, followed by surgery or radiotherapy in unresectable stage III NSCLC and without EGFR/ ALK alterations. Methods: Patients with MDT-assessed surgically unresectable disease were given 3 cycles of neoadjuvant SHR-1701 (30 mg/kg Q3W) with or without chemotherapy (paclitaxel 175 mg/m2 Q3W + carboplatin AUC = 5 Q3W).Patients with PD-L1 TPS < 50% received combination therapy (arm A) and those with PD-L1 TPS ≥50% were randomized (1:1) to receive combination therapy (arm B) or SHR-1701 alone (arm C). After reassessment by MDT, patients received either surgery or definitive radiotherapy (60 Gy/30 fractions) plus concurrent cisplatin (30 mg/m2 QW), all followed by consolidation SHR-1701 for 16 cycles. The primary endpoints were post-induction objective response rate (ORR) and 18-month event-free survival (EFS) rate. Arm A+B (patients receiving neoadjuvant chemoimmunotherapy) was the primary analysis cohort. Results: Between Nov. 20, 2020 and Jan. 27, 2022, 107 patients were enrolled (arm A/B/C, n = 88/9/10). Median follow-up was 22.2 months. In arm A+B, both primary endpoints were met, with a post-induction ORR of 58% (95% CI 47-68) and an 18-month EFS rate of 56.6% (95% CI 45.2-66.5). In arm C, the post-induction ORR was 40% (95% CI 12-74) and 18-month EFS rate was 77.1% (95% CI 34.5-93.9). 24-month overall survival rate was 78.3% (95% CI 68.0-85.7) in arm A+B and 100% in arm C. Overall, 27 (25% of 107; arm A+B/C, n = 24/3) patients underwent surgery; all achieved R0 resection. Among them, 12 (44%) MPR and seven (26%) pCR were recorded. The 18-month EFS rate was 74.1% (95% CI 53.2-86.7) in resected patients and 57.3% (43.0-69.3) in those receiving radiotherapy. Across arms, all grade ≥3 TRAEs with frequency ≥10% were hematological toxicities. No new safety signals were identified. Conclusions: NeoadjuvantSHR-1701 with chemotherapy, followed by surgery or radiotherapy, showed promising anti-tumor activity with a tolerable safety profile in unresectable stage III NSCLC. We provided first evidence that surgical conversion was feasible in a notable proportion of patients, and was associated with better survival outcomes. Clinical trial information: NCT04580498 .
