RESUMEN

Despite flow-electrode capacitive deionization (FCDI) is an emerging technology for desalination, contaminant removal, and resource recovery, the application of conventional FCDI in wastewater treatment is hindered by the electrode selectivity and material costs. In this study, we synthesized a low-cost ammonium (NH4+) adsorption electrode material by modifying zeolite using ethylenediaminetetraacetic acid disodium salt (EDTA-2Na). The flow electrode prepared by the mixture of EDTA-zeolite and carbon black exhibits a high selectivity and adsorption capacity for the recovery of NH4+ from wastewater. The NH4+ in wastewater passes through the ion exchange membrane and is rapidly adsorbed by the modified zeolite through ion exchange, while Na+ is retained in the electrolyte. The decrease in NH4+ concentration and the increase in Na+ concentration in the catholyte lead to a significant change in ion concentration gradient across the membrane. Consequently, the transmembrane selectivity between NH4+ and Na+ reached 3.46. We validated the feasibility of NH4+ recovery using FCDI with food waste fermentation supernatant. Under optimal operating conditions, 99.15 % of the NH4+ in the fermentation supernatant was removed, and 95.92 % of the NH4+ in the electrolyte was stored in the EDTA-zeolite. By gravitational settling, the NH4+-rich modified zeolite was separated from carbon black and could be utilized as nitrogen fertilizer. Meanwhile, the mixture of carbon black and brine was used to prepare a fresh electrode suspension. In brief, the FCDI system exhibits a satisfying NH4+ recovery performance and demonstrates a sustainable wastewater resource recovery strategy.

RESUMEN

Oncolytic viral immunotherapy is a cancer treatment that uses native or genetically modified viruses that selectively replicate and destroy tumor cells. In this study, we aimed to construct a virus-based prognostic model for risk assessment and prognosis prediction in patients with hepatocellular carcinoma (HCC) and determine the most appropriate virus as a candidate vector for oncolytic virus immunotherapy. Microbiome and RNA sequencing data and clinical information were obtained from The Cancer Genome Atlas, and viruses with prognostic value were identified (Deltabaculovirus, Sicinivirus, and Cytomegalovirus) to construct the prognostic model. Correlation analyses were performed to evaluate the predictive function of the viral signature. Bioinformatics analyses were conducted to explore the functional enrichment of viral expression in HCC. The risk score generated by this model could distinguish patients with different survival outcomes, have excellent reliability and accuracy, and could be used as an independent prognostic indicator. The high-risk score group showed significantly lower overall survival, and this trend was also observed in subgroups with different clinicopathological features. Furthermore, Deltabaculovirus positively correlated with amino acid metabolism, energy metabolism signaling pathways, peroxisomes, and complement coagulation cascades. In addition, Deltabaculovirus was significantly related to immune cell infiltration; therefore, patients with high Delta-baculovirus expression might respond better to HCC immunotherapy. Our study identified a promising predictive viral signature for assessing clinical prognosis and guiding immunotherapy in HCC. Deltabaculovirus might be a suitable viral vector for oncolytic virus immunotherapy.

RESUMEN

Electrochemical extraction has the potential to enhance uranium (U) extraction capacity and rates, but thus far, high selectivity and energy efficiency have not been achieved through the design of electrode materials. Herein, a precise electrocatalysis strategy is developed using a Ferrum (Fe) porphyrin-phenanthroline conjugated network (Fe@PDACN) for energy-efficient uranium extraction. The phenanthroline provides specific binding sites for selective enrichment of U(VI) at active sites (Kd = 2.79 × 105 mL g-1 in multi-ion solution). The Fe(II) sites have strong trap-redox activity for U(VI) and act as dynamic electron donors to rapidly mediate electrocatalytic U(VI) extraction through the redox reaction of Fe(0/II)/Fe(III). Moreover, the Fe-porphyrin blocks support sustained electron donation for U(VI) electrocatalysis by pre-storing electrons. These features enable selective uranium capture and a high electroextraction capacity of 24 646.3 mg g-1 from simulated nuclear wastewater in 280 h at a low voltage of -1.5 V. An ultra-high Faraday efficiency of 90.1% is achieved, and the energy cost is 3.22 × 10-2 $ kg-1 U, significantly lower than the previously reported materials. This work provides a highly efficient strategy for uranium extraction from water.

RESUMEN

OBJECTIVE: To assess the performance of simultaneous endometrial aspiration and sonohysterography to screen for endometrial cancer or hyperplasia in women aged 50 years or older. METHODS: We conducted a prospective study from February 2014 to October 2020 at the ultrasound unit of a large urban academic medical center. The study included 1,635 women aged 50 years or older referred for endometrial evaluation, with follow-up through January 2021. Participants underwent saline infusion sonohysterography combined with ultrasound-guided endometrial aspiration. The primary outcome measured was a diagnosis of endometrial cancer or hyperplasia within 1 year from screening. The diagnostic accuracy of the combined evaluation method, including sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV), was assessed. RESULTS: Of 1,170 women who completed the study protocol, 82 (7.0%) had endometrial cancer and 42 (3.6%) had endometrial hyperplasia. Of all patients who developed cancer during the follow-up period, 85.5% were diagnosed within 1 year after evaluation. The application of simultaneous endometrial aspiration and sonohysterography together demonstrated a sensitivity of 99.1%, specificity of 24.9%, PPV of 11.8%, and NPV of 99.6%. Using a theoretical sequential approach, assuming an endometrial aspiration is performed only in patients determined to be high risk by sonohysterography, demonstrated a sensitivity of 93.4%, specificity of 99.9%, PPV of 99.0%, and NPV of 99.3%. CONCLUSION: Simultaneous endometrial aspiration and sonohysterography is an effective one-stop outpatient screening tool for detecting endometrial cancer and hyperplasia in women aged 50 years or older. With the integration of two screening modalities into a single procedure, simultaneous endometrial aspiration and sonohysterography may overcome the limitations inherent in each of the currently recommended methods individually, potentially improving patient prognosis and streamlining the diagnostic process.

RESUMEN

ABSTRACT: BACKGROUND: Planned tracheal extubation failure is a common occurrence among patients in the neurosurgical intensive care unit (NICU) because of the complex nature of neurocritical injuries, and the failure could result in a poor prognosis. METHODS: We observed and recorded the patients with tracheal intubation in the NICU of a hospital in Shanghai from June 2021 to December 2022 and analyzed data from planned tracheal extubation, categorizing patients by success or failure, and compared outcomes between the two groups while investigating contributing factors. RESULTS: A total of 156 patients were included, 133 (85.3%) of whom were successfully extubated and 23 (14.7%) were not. The results of logistic regression analysis demonstrated that the Glasgow Coma Scale score before extubation (OR, 0.643; 95% CI, 0.444-0.931; P = .020) and the frequency of respiratory secretions suctioning before tracheal extubation (OR, 0.098; 95% CI, 0.027-0.354; P < .001) were independent risk factors for extubation failure. We also found that the extubation failure group experienced a significantly longer ICU stay and incurred higher hospitalization costs. CONCLUSIONS: Poor Glasgow Coma Scale scores and a high frequency of respiratory secretions suctioning before tracheal extubation were the main factors contributing to tracheal extubation failure in NICU patients. To avoid tracheal extubation failure and adverse outcomes, these two factors should be carefully assessed before tracheal extubation.

RESUMEN

Purpose: Primary surgery failure of macular holes causes poor visual acuity outcomes. Several studies indicate that small-medium idiopathic full-thickness macular holes (iFTMH) have consistent and high anatomical closure rates after vitrectomy and internal limiting membrane (ILM) peeling, regardless of iFTMH diameters. However, there is no systematic analysis examining the relationship between iFTMH diameters and anatomical closure rates. Methods: In this systematic review and meta-regression, we searched PubMed, Embase, and Web of Science databases on October 24th, 2022. We included studies regarding iFTMH, with ILM peeling/inverted flap technique, long-lasting gas tamponade, and face-down position after surgery. Univariable meta-regression with a restricted cubic spline model and component-plus-residual plot after covariables adjustment were used to explore non-linear association. Results: A total of 7257 participants from 19 randomized controlled trials and 49 observational studies were included in this meta-analysis. In ILM peeling group, every 100-µm increment in diameter was associated with a 3.8 % (95 % confidence interval [CI], 1.8%-5.7 %, P < 0.001) relatively lower anatomical closure rate. Yet, among studies using the inverted flap technique, baseline iFTMH diameter was not associated with a lower anatomical closure rate (0.2 %, 95%CI, -4.2 %-4.5 %, P > 0.9). The restricted cubic spline model and component-plus-residual plot controlling for age, sex, and symptom duration prior to surgery showed no evident non-linearity in both surgical techniques. Conclusions: The iFTMH diameter is linear and inversely associated with the anatomical closure rate after the ILM peeling technique, but not with the inverted flap technique. The present study supports the use of advanced techniques, e.g., inverted flap technique, in small-medium iFTMH to improve anatomical closure rates.

RESUMEN

Coronary heart disease (CHD) is one of the leading causes of mortality and morbidity in the United States. Accurate time-to-event CHD prediction models with high-dimensional DNA methylation and clinical features may assist with early prediction and intervention strategies. We developed a state-of-the-art deep learning autoencoder survival analysis model (AESurv) to effectively analyze high-dimensional blood DNA methylation features and traditional clinical risk factors by learning low-dimensional representation of participants for time-to-event CHD prediction. We demonstrated the utility of our model in two cohort studies: the Strong Heart Study cohort (SHS), a prospective cohort studying cardiovascular disease and its risk factors among American Indians adults; the Women's Health Initiative (WHI), a prospective cohort study including randomized clinical trials and observational study to improve postmenopausal women's health with one of the main focuses on cardiovascular disease. Our AESurv model effectively learned participant representations in low-dimensional latent space and achieved better model performance (concordance index-C index of 0.864 ± 0.009 and time-to-event mean area under the receiver operating characteristic curve-AUROC of 0.905 ± 0.009) than other survival analysis models (Cox proportional hazard, Cox proportional hazard deep neural network survival analysis, random survival forest, and gradient boosting survival analysis models) in the SHS. We further validated the AESurv model in WHI and also achieved the best model performance. The AESurv model can be used for accurate CHD prediction and assist health care professionals and patients to perform early intervention strategies. We suggest using AESurv model for future time-to-event CHD prediction based on DNA methylation features.

RESUMEN

In recent years, carbon monoxide (CO) has garnered increased attention as a novel green therapy for hepatocellular carcinoma (HCC) treatment. However, the CO donor is still limited in clinical application due to its lack of targeted ability and unstable release rate. Here, self-assembled amphiphilic nanomicelles glucose-polyethylene glycol (PEG)-lipoic acid (LA)-Fe2(CO)6 (Glu-Fe2(CO)6) are first designed as a CO donor and synthesized via a chemical method, combining glucose with Fe2(CO)6 through PEG-LA. Some advantages of this tumor-targeted Glu-Fe2(CO)6 delivery system include (I) good water-solubility, (II) the glutathione responsive CO slow release, (III) the active tumor-targeted ability of glucose as targeted ligands, and (IV) outstanding efficacy of antitumor and safety of CO therapy of HCC both in vitro and in vivo. These findings suggest that Glu-Fe2(CO)6 nanomicelles hold promise for enhancing antitumor therapeutic capabilities, presenting a novel tumor-targeted delivery strategy in gas therapy for HCC treatment.

RESUMEN

The remediation of soil pollution by heavy metals (HMs) presents a significant challenge in environmental restoration. Stabilization remediation technology has proven effective in treating HMs contaminated soil. However, its development is constrained by drawbacks such as slow reaction kinetics and low adsorption capacity. This research synthesized a nano-SiO2@iron­phosphorus (FPOH) material by SiO32- encapsulating the iron-phosphate precipitate obtained from Fe ion and phosphate. In addition, this research applied this material to ferrallisols, calcareous soils and organic soils with three different levels of high pollution by Cd, Pb, Cu and Zn. The experimental results indicate that all experimental soils stabilized rapidly within 1 day and met the requirements of remediation engineering standards (ChinaMEE HJ 1282-2023). Analysis of the possible mechanisms suggests that the FPOH material effectively fills voids with phosphate mineral formation, preventing the secondary release of HMs. During the stabilization process, FPOH involves the adsorption of free ions and small organic molecules in the soil, which does not affect its high reactivity. The development and utilization of FPOH offer valuable insights for soil stabilization remediation.

RESUMEN

AIMS: To quantitatively measure retinal curvature (RC) in children with myopia and explore its association with refractive status. METHODS: This cross-sectional study included participants aged 5-18 years who underwent comprehensive ocular examinations, including cycloplegic refraction and macula 24×20 mm optical coherence tomography (OCT) scans. RC was derived from OCT data using a three-dimensional reconstruction system. Mean RC was assessed in concentric circles (RC I-VI) with diameters of 1, 3, 6, 9, 12 and 15 mm around the fovea, as well as in four orientations (RC S/I/N/T). RESULTS: A total of 443 eyes were included in the analysis. The values from RC I to RC VI were 0.51±0.19, 0.53±0.19, 0.62±0.19, 0.76±0.23, 0.86±0.23 and 0.81±0.18 10-2mm-2, respectively. RC I exhibited the smallest curvature, while RC V displayed the highest (p<0.001). High myopia (HM) group demonstrated larger RC I and smaller RC III/IV/V/VI compared with low myopia (LM) group (p<0.01). Significant differences among RC S/I/N/T were observed in HM group (pairwise comparison, p<0.001), but not in LM group. Multiple regression analysis revealed that age, sex, corneal curvature radius and subfoveal choroidal thickness (SFCT) were associated factors with foveal RC, while age, SFCT and axial length (AL) were associated factors of peripheral RC. CONCLUSION: RC can quantitatively characterise retinal shape and the morphological changes induced by myopia. Myopia progression results in a bulging macular retina accompanied by a flattening peripheral retina in children, and also increases the irregularity among the four quadrants. Age, AL and SFCT are associated factors of RC.

RESUMEN

BACKGROUND: To examine if pregnancy affects the prognosis of uveal melanoma (UM) patients undergoing plaque brachytherapy (PBT) and to assess if PBT has any subsequent impact on pregnancy outcomes. METHODS: A retrospective, single-center study was carried out at Beijing Tongren Hospital, focusing on women of childbearing age diagnosed with UM and treated with iodine-125 plaque brachytherapy. Both the outcomes of pregnancies and the health status of the fetuses were monitored. Survival analyses were conducted using the Kaplan-Meier method, with endpoints being metastasis and death. RESULTS: A total of 13 patients who had full-term pregnancies and 96 non-pregnant women matched by age and tumor size were included. The mean follow-up time was 67.0 ± 27.7 months (median:66.0 months, range:21.0 to 116.0 months). In the pregnant group, two patients developed metastases, one of whom died shortly after delivery; local recurrence of UM occurred in 2 patients after or during delivery, and 2 other patients developed secondary glaucoma due to radiation retinopathy. None of the other pregnant patients reported any signs of disease progression. In the control group, 18 metastasis cases including 12 deaths were documented. Pregnant patients and matched control subjects showed no statistical difference in both Metastasis-free survival (hazard ratio (HR): 0.66, 95% confidence interval (CI): 0.15-2.86; P = 0.576) and overall survival (HR: 0.48, 95% CI: 0.06-3.66; P = 0.464). All pregnant patients carried the pregnancy to term and delivered healthy children with no report of placental or infant metastases to date. CONCLUSION: Pregnancy does not appear to negatively impact the prognosis of UM patients undergoing PBT. PBT showed no observable detriment to maternal fertility and exhibited no teratogenic effects on the fetus. However, the long-term implications of PBT on pregnancy remain uncertain, necessitating additional, prolonged follow-up studies.

RESUMEN

Alterations in the reward and cognitive control systems are commonly observed among adolescents with internet dependence (ID), and this impairment is often accompanied by social dysfunctions, such as academic burnout. However, the intercorrelations among ID, reward, cognitive control processing, and learning burnout remain unclear. We recruited 1074 Chinese adolescents to investigate the complex interrelationships among these variables using network analysis. The resulting network revealed patterns that connected ID to the behavioral inhibition/activation system (BIS/BAS), self-control, and learning burnout; these results exhibited reasonable stability and test-retest consistency. Throughout the network, the node of BAS-drive was the critical influencing factor, and the node of self-control was the protection factor. In addition, several symptoms of learning burnout and ID were positively associated with sensitivity to punishment. As revealed by the network comparison test, the network constructed among internet dependent (ID) group differed from the network constructed among internet nondependent (IND) group not only in the edges between BIS and learning burnout but also in terms of the edges associated with learning burnout. In conclusion, this study provides insights into the complex mechanisms underlying ID among adolescents from the perspective of the network relationships between core influencing factors and negative consequences. It validates the dual-system model of risky behavior among adolescents and offers a foundation for early warning and interventions for ID in this context.

RESUMEN

Bladder cancer (BC) ranks as the sixth cancer in males and the ninth most common cancer worldwide. Conventional treatment modalities, including surgery, radiation, chemotherapy, and immunotherapy, have limited efficacy in certain advanced instances. The involvement of GALNT6-mediated aberrant O-glycosylation modification in several malignancies and immune evasion is a subject of speculation. However, its significance in BC has not been investigated. Through the integration of bioinformatics analysis and laboratory experimentation, we have successfully clarified the role of GALNT6 in BC. Our investigation revealed that GALNT6 has significant expression in BC, and its high expression level correlates with advanced stage and high grade, leading to poor overall survival. Moreover, both in vitro and in vivo experiments demonstrate a strong correlation between elevated levels of GALNT6 and tumor growth, migration, and invasion. Furthermore, there is a negative correlation between elevated GALNT6 levels, the extent of CD8+ T cell infiltration in the tumor microenvironment, and the prognosis of patients. Functional experiments have shown that the increased expression of GALNT6 could enhance the malignant characteristics of cancer cells by activating the epithelial-mesenchymal transition (EMT) pathway. In brief, this study examined the impact of GALNT6-mediated abnormal O-glycosylation on the occurrence and progression of bladder cancer and its influence on immune evasion. It also explored the possible molecular mechanism underlying the interaction between tumor cells and immune cells, as well as the bidirectional signaling involved. These findings offer a novel theoretical foundation rooted in glycobiology for the clinical application of immunotherapy in BC.

RESUMEN

The potential effects of probiotics on lowering lipid accumulation and alleviating gut microbiota perturbation have been extensively substantiated, but whether Lactobacillus rhamnoses-fermented oyster mushroom (FOM) could more pronouncedly attenuate obesity remains unclear. In this study, the anti-obesity effect of FOM was estimated based on the gut microbiota profile and analysis of hepatic lipid metabolic characteristics. The results revealed that FOM intervention dramatically improved hepatic lipid accumulation, characterized by reduction in fat-related factor metabolism levels and liver lesion enzymatic activities and down-regulation of the expression of genes associated with glycolipid metabolism (Foxo1, Gck, G6pd, Il6r and IL-ß). Metabolomics analysis indicated HFD-induced dysglycaemia and disturbed amino acid metabolism, characterized by significant enrichment of pathways (butanoate metabolism, arginine biosynthesis, etc.) and elevated levels of D-mannose, succinate and ß-D-fructose, followed by a decreased galactitol content. Furthermore, FOM intervention showed significant enrichment of specific pathways, particularly transcriptional misregulation in cancer and FoxO signaling pathways, while the MAPK signaling pathway demonstrated consistent enrichment across all experimental groups. FOM intervention reshaped the gut microbiota structure by facilitating the proliferation of SCFA producers (Romboutsia, Ruminococcaceae and Allobaculum), together with the depletion of Lachnospiraceae population. The current study strengthened our understanding of FOM prebiotic activities and obesity alleviation mechanisms.

RESUMEN

OBJECTIVE: To evaluate the impact of preimplantation genetic testing for aneuploidy (PGT-A) on first transfer live birth rate (LBR) and cumulative LBR (CLBR) in donor oocyte in vitro fertilization (IVF) cycles. DESIGN: Retrospective cohort study of the Society for Assisted Reproductive Technology Clinic Outcome Reporting System database. SETTING: Fertility centers reporting to Society for Assisted Reproductive Technology. PATIENT(S): A total of 11,348 fresh and 7,214 frozen-thawed donor oocyte IVF cycles were analyzed. INTERVENTION(S): The first reported donor stimulation cycle per patient between January 1, 2014, and December 31, 2015, and all linked embryo transfer cycles between January 1, 2014, and December 31, 2016, were included in the study. MAIN OUTCOME MEASURE(S): Live birth rate was compared for patients using fresh and frozen-thawed donor oocytes, with or without PGT-A. Logistic regression models were adjusted for age, body mass index, gravidity, infertility etiology, and prior IVF cycles. RESULT(S): Among patients who had blastocysts available for transfer or PGT-A, the use of PGT-A was associated with a decreased first transfer LBR (46.9 vs. 53.2%) and CLBR (58.4 vs. 66.6%) in fresh oocyte donor cycles compared with no PGT-A. Live birth rate in frozen-thawed oocyte donor cycles with PGT-A were nominally higher than those without PGT-A (48.3% vs. 40.5%) but were not statistically significant in multivariable logistic regression models. Early pregnancy loss was not significantly different with and without PGT-A. Multiple gestation, preterm birth, and low birth weight infants were all reduced with the addition of PGT-A in fresh donor oocyte cycles, although these outcomes were not significantly different when comparing single embryo transfers in fresh oocyte cycles and also not significantly different among frozen-thawed donor oocyte cycles. CONCLUSION(S): Preimplantation genetic testing for aneuploidy in fresh oocyte donor cycles was associated with decreased LBR and CLBR, whereas effects on frozen-thawed oocyte donor cycles were clinically negligible. Obstetric benefits associated with PGT-A in fresh donor cycles appear linked to increased single embryo transfer.

RESUMEN

An advanced biodegradable packaging film with antimicrobial and fresh-maintaining functions was constructed by incorporating berberine and L-arginine into the starch/polyvinyl alcohol (PVA) film matrix. The film was endowed with a dual antibacterial capacity thanks to the intrinsic antibacterial capability of berberine and cascaded photodynamic sterilization. The aggregated berberine presents an excellent photodynamic activity to generate reactive oxygen species (ROS), which further triggers the NO release from L-arginine. Under the synergetic action of ROS and NO, the as-prepared film not only has an antibacterial efficiency of over 99 % against both S. aureus and E. coli but also delays fruit ripening through antagonistic effects on ethylene to extend the shelf life of food. Meanwhile, the as-prepared film presents UV-shielding properties, thermal stability, and considerable mechanical properties. Specifically, the packaging film exhibits good biocompatibility and is biodegradable, with a degradation rate of 56 % within 16 days, which has great potential for improving food safety and environmental events.

RESUMEN

OBJECTIVE: To determine whether industry payments to physicians are associated with a difference in assisted reproductive technology practices and outcomes. DESIGN: Retrospective cohort. SETTING: Assisted reproductive technology centers. PATIENT(S): Patients undergoing asissted reproduction. INTERVENTION(S): Industry payments reported to the Open Payments 2020 database. MAIN OUTCOME MEASURE(S): The live birth rate, frozen embryo transfer (FET) rate, intracytoplasmic sperm injection (ICSI) rate, preimplantation genetic testing (PGT) rate, and percentage of patients aged >40 years were obtained from the Centers for Disease Control and Prevention 2020 database. Linear regression analysis was performed comparing the percentage of physicians per center receiving industry payments to clinic-level outcomes. RESULT(S): A total of 873 reproductive endocrinology and infertility physicians received payments in the 2020 database. At least one physician received a payment in 80.5% (437/543) of in vitro fertilization centers. Of 1,724 reproductive endocrinology and infertility physicians, 873 (50.6%) received at least one payment in 2020. The live birth, ICSI, FET, and PGT rates and percentage of patients aged >40 years did not significantly differ between centers by percentage of physicians receiving industry payments. However, in the subanalysis of 99 large centers (defined as ≥5 physicians), each increase in the percentage of physicians receiving industry payments was associated with increases of 0.20% (95% confidence interval, 0.02-0.39) and 0.14% (95% confidence interval, 0.05-0.24) in the PGT and FET rates, respectively. The live birth, ICSI rates and percentage of patients aged >40 years were not associated with increased industry payment rates to physicians. CONCLUSION(S): Industry payments were not associated with differences in in vitro fertilization center outcomes overall. However, large centers with more physicians receiving industry payments may be more likely to use additional procedures such as PGT and FET, without improvement in the final outcomes such as the live birth rate. Further research is needed to determine whether these differences reflect the industry payment influence vs. individual center/provider practice habits in larger practices.

RESUMEN

BACKGROUND: The prognosis nutritional index (PNI) and the systemic inflammatory immunological index (SII) are characteristic indicators of the nutritional state and the systemic inflammatory response, respectively. However, there is an unknown combined effect of these indicators in the clinic. Therefore, the practicality of using the SII-PNI score to predict prognosis and tumor response of locally advanced gastric cancer (LAGC) following chemotherapy was the main focus of this investigation. METHODS: We retrospectively analyzed 181 patients with LAGC who underwent curative resection after neoadjuvant chemotherapy in a prospective study (NCT01516944). We divided these patients into tumour regression grade(TRG) 3 and non-TRG3 groups based on tumor response (AJCC/CAP guidelines). The SII and PNI were assessed and confirmed the cut-off values before treatment. The SII-PNI values varied from 0 to 2, with 2 being the high SII (≥ 471.5) as well as low PNI (≤ 48.6), a high SII or low PNI is represented by a 1 and neither is represented by a 0, respectively. RESULTS: 51 and 130 samples had TRG3 and non-TRG3 tumor responses respectively. Patients with TRG3 had substantially higher SII-PNI scores than those without TRG3 (p < 0.0001). Patients with greater SII-PNI scores had a poorer prognosis (p < 0.0001). The SII-PNI score was found to be an independent predictor of both overall survival (HR = 4.982, 95%CI: 1.890-10.234, p = 0.001) and disease-free survival (HR = 4.763, 95%CI: 1.994-13.903, p = 0.001) in a multivariate analysis. CONCLUSION: The clinical potential and accuracy of low-cost stratification based on SII-PNI score in forecasting tumor response and prognosis in LAGC is satisfactory.

RESUMEN

A novel sandwich-type electrochemical immunosensor for the detection of the liver cancer marker alpha-fetoprotein (AFP) in human serum is proposed. The two-dimensional MXene material Ti3C2Tx was first prepared using etching and ultrasonic stripping, and then Ti3C2Tx was used to reduce chloroauric acid to form Ti3C2Tx/AuNP composites which were modified on the surface of the glassy carbon electrodes to form probe-type sensors. The Ti3C2Tx/AuNPs provide a large number of binding sites for the AFP capture antibody (Ab1) and increase the electrochemical reaction active site. The Ti3C2Tx/copper metal-organic frameworks HKUST-1 composite was also prepared by solvothermal method and combined with toluidine blue (TB) and AFP detection antibody (Ab2) to form a labeled sandwich-type electrochemical immunosensor. The sensor achieved trace detection of AFP from 0.1 to 100 ng/mL with a detection limit of 0.073 pg/mL and possesses good selectivity, stability, and reproducibility. The sensor performs well in clinical samples and has good potential for clinical applications.

RESUMEN

BACKGROUND: Mechanistic studies of the effects of environmental risk factors have been exploring the potential role of microRNA(miRNAs) as a possible pathway to clinical disease. In this study we examine whether levels of toenail metals are associated with changes in extracellular miRNA(ex-miRNA) expression. METHODS: We used data derived from the Normative Aging Study from 1996 to 2014 to conduct our analyses. We looked at associations between measured toenail metals: arsenic, cadmium, lead, manganese, and mercury and 282 ex-miRNAs in this population using canonical correlation analyses (CCAs) and longitudinal median regression. We adjusted for covariates such as age, education, body mass index, drinking and smoking behaviors, diabetes, and where available, seafood consumption. The p-values obtained from regression analyses were corrected for multiple comparisons. Ex-miRNAs identified to be associated with toenail metal levels were further examined using pathway analyses. RESULTS: Our dataset included 937 observations from 589 men with an average age of 72.9 years at baseline. Both our correlation and regression analyses identified lead and cadmium as exposures most strongly associated with ex-miRNA expression. Numerous ex-miRNAs were identified as being associated with toenail metal levels. miR-27b-3p, in particular, was found to have high correlation with the first canonical dimension in the CCA and was significantly associated with cadmium in the regression analysis. Pathway analyses revealed messenger RNA (mRNA) targets for the ex-miRNAs that were associated with a number of clinical disorders including cancer, cardiovascular disease, and neurological disorders, etc. CONCLUSION: Toenail metals were associated with changes in ex-miRNA levels in both correlational and regression analyses. The ex-miRNAs identified can be linked to a variety of clinical disorders. Further studies are required to validate these findings.
