A good ultrasensitive ratiometric immunosensor using the rates involving conjugated distyrylbenzene kind nanosheets together with AIECL components and also electrochemical sign for CYFRA21-1 discovery.
Compared with conventional radioimmunotherapy, the combination of CIRT with anti-PD-1 more efficiently triggered traits of immunogenic cell death including the exposure of calreticulin, the release of adenosine triphosphate (ATP), the exodus of high-mobility group box 1 (HMGB1) as well as the induction of type-1 interferon responses. In addition, CIRT plus anti-PD-1 led to an increased infiltration of CD4+, and CD8+ lymphocytes into the tumor bed, significantly decreased tumor growth and prolonged survival of melanoma bearing mice. We herein provide evidence that CIRT-triggered immunogenic cell death, enhanced tumor immunogenicity and improved the efficacy of subsequent anti-PD-1 immunotherapy.Accumulated oncometabolites in the tumor microenvironment (TME) suppresses the metabolism, expansion, and function of T cells. Immunosuppressive TME also impeded Chimeric Antigen Receptor (CAR)-T cells mediated cytotoxicity since CAR-T cells had to adapt the in vivo metabolic characteristics with high levels of oncometabolites. We screened oncometabolites for the inhibition of glucose uptake in CD8 + T cells and found Kynurenine (Kyn) showed the strongest inhibiting effect on glucose uptake. In vitro experiments showed that 120 μM Kyn treatment in CD8 + T cells resulted in inhibiting the expansion of CD8 + T cells, decreasing the production of granzyme B and interferon-γ. CAR-T cells mediated cytotoxicity was also impaired by the high Kyn treatment from killing assay. We then explored the anti-tumor effect of Kynureninase (KYNU) modified CAR-T cells through catabolism o oncometabolites Kyn. KYNU over-expression (OE) CAR-T cells showed a superior killing effect against cancer cells even in the immunosuppressive TME with high Kyn levels. In vivo experiments confirmed KYNU-OE CAR-T cells showed an excellent anti-tumor effect in a TME with high Kyn levels since it improved the survival of mice bearing NALM6 cancer cells and NALM6-IDO1 cancer cells. The KYNU-modified CAR-T cells displayed distinct phenotypes related to the expansion, function, and memory differentiation status of CAR-T cells. This study explores an immunotherapy strategy for patients with alterations in Kyn metabolism. KYNU-OE CAR-T cells take advantage of Kyn catabolism to improve anti-tumor activity in the metabolic immunosuppressive TME with high Kyn.
Several inflammation-based scores have prognostic value for patients diagnosed with various cancers. However, using only a single inflammation-based prognostic score may be unreliable, as the cut-off values and relative usefulness among various inflammation-based prognostic scores vary. We established a new combined index of four inflammation-based prognostic scores, namely the neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, prognostic index, and prognostic nutritional index, and assessed its usefulness to predict the prognosis of gastric cancer.

We reviewed the data of 635 patients who underwent surgical resection for gastric cancer. We calculated the combined index as the total value of each of the four included inflammation-based prognostic scores and analyzed the relationship between the combined index and postoperative prognosis of gastric cancer. The new combined index was represented as a value between 0 and 6 in each patient. The Kaplan-Meier survival curves showed that patients whose combined index was 0 had good long-term outcomes, while the prognosis of patients whose combined index ranged from 4 to 6 was poor.

This new combined index was strongly associated with poor prognosis in patients who underwent surgery for gastric cancer. It is inferred that it can predict patient prognosis after surgical resection for gastric cancer with a stronger correlation and clearer stratification than a single inflammation-based prognostic score.

Beta blockers combined with endoscopic variceal band ligation (EVL) is the most effective means for the prevention of variceal rebleeding. No data are available on the efficacy of carvedilol in the secondary prophylaxis of variceal bleeding in hepatosplenic schistosomiasis. The aim of this study was to evaluate the efficacy and safety of carvedilol compared to propranolol as secondary prophylaxis of variceal bleeding in hepatosplenic schistosomiasis.

This was a prospective, randomized study over a period of 14 months from February 2019 to March 2020. All patients with portal hypertension due to schistosomiasis with at least one episode of variceal bleeding were included and randomized to the propranolol and carvedilol groups. EVL protocol was continued in both groups.

Sixty-one patients were eligible and randomized to propranolol (
= 30) and carvedilol (
= 31) groups. There was no significant difference in hemorrhagic recurrence between the carvedilol (
= 1) and propranolol (
= 3) groups (3.33 vs 10%;
= 0.30). At 4months, there was a significant reduction in mean arterial pressure (-4.13 mm Hg; 95% CI -6.27 to -1.99;
< 0.05) and heart rate (-12.13 bpm; 95% CI -13.92 to -10.35;
< 0.05) in the carvedilol group. There was no significant difference between the groups on the mean difference in arterial pressure. One patient in the carvedilol group had breathing difficulty. There were no adverse events in the propranolol group.

There was no significant difference in the efficacy between carvedilol and propranolol. Carvedilol may be an alternative to propranolol for secondary prophylaxis of variceal rebleeding in hepatosplenic schistosomiasis.

Colonic wall thickening (CWT) is commonly associated with clinically significant pathologies, but predictive factors of such pathologies are not well known. This study aims to identify the predictors of clinically significant pathologies, such as colorectal carcinoma (CRC) and inflammatory bowel disease (IBD), in patients with CWT.

Subjects with an abnormal abdominal computed tomography (CT) and a follow-up colonoscopy between 2010 and 2020 were retrospectively reviewed. Patients with CWT in the CT were included and examined in this study. A multivariable logistic regression analysis was performed to assess for factors independently associated with CRC or IBD in these subjects. Receiver operating characteristic (ROC) curve analysis was used to further examine significant parameters in multivariable logistic regression analysis.

Among 403 patients with CWT on CT scans who underwent a colonoscopy, 269 subjects who met the inclusion criteria were identified and studied. On multivariable logistic regression models, elevated platelet count, low hematocrit, and localized CWT were found to be independently associated with CRC, while elevated platelet count and younger age were independently associated with IBD. On ROC curve analysis for CRC, area under the curve (AUC) for hematocrit, platelets, and localized CWT was 0.76, 0.75, and 0.61, respectively. On ROC curve analysis for IBD, AUC for age and platelets was 0.90 and 0.69, respectively.

Elevated platelet count, low hematocrit, and localized CWT can be potentially used as predictors of CRC in patients with CWT. Elevated platelet count and young age can be used to predict IBD in these patients.

The risk factors for lymph node metastasis (LNM) of duodenal neuroendocrine tumors (DNETs) are not well identified, and a definitive standard of treatment for DNETs has not been established. In this study, we aimed to identify the risk factors for LNM and establish the indication of local resection for DNETs.

We retrospectively reviewed 55 patients with 60 non-ampullary and nonfunctional DNETs. We evaluated the risk factors for LNM and compared the outcomes between endoscopic resection (ER) for DNETs <5 mm and laparoscopy and endoscopy cooperative surgery (LECS) for DNETs ≥5 mm.

LNM was present in four (8.7%) patients. Univariate analysis revealed that tumor size ≥10 mm, positive lymphovascular invasion (LVI), and 0-Is morphology were significantly associated with LNM (
=0.008,
=0.037, and
=0.045, respectively). ER and LECS were performed for 18 and 11 DNETs, respectively. All lesions treated with ER or LECS were confined to the submucosal layer. The median tumor size was 3 mm in ER and 6 mm in LECS. Although there was no significant difference in the R0 (no residual tumor) resection rate, R0 resection was completely achieved in the LECS. No significant differences were observed in terms of complication rates. No recurrence was observed in any of the groups.

Tumor size ≥10 mm, positive LVI, and 0-Is morphology were significant risk factors for LNM. We demonstrated that ER is feasible and could be safely applied for DNETs <5 mm, and LECS could be applied for DNETs 5-10 mm in size.
Tumor size ≥10 mm, positive LVI, and 0-Is morphology were significant risk factors for LNM. We demonstrated that ER is feasible and could be safely applied for DNETs less then 5 mm, and LECS could be applied for DNETs 5-10 mm in size.
Studies detailing endoscopic findings and hemostatic interventions for upper gastrointestinal bleeding after cardiovascular surgery are scarce. We conducted this study to determine the frequency and findings of emergent esophagogastroduodenoscopy (EGD) after cardiovascular surgery and the effect of bleeding requiring hemostatic intervention on clinical outcomes.

We retrospectively reviewed records of emergent EGD examinations conducted within 30 days after cardiovascular surgery at a tertiary referral center in Japan from April 2011 to March 2020. Of 1625 patients undergoing cardiovascular surgery, 47 underwent emergent EGD. Sources of bleeding were identified in 30 cases, including transesophageal echocardiogram (TEE)-related injuries (8 patients), gastric ulcers (7 patients), and duodenal ulcers (7 patients). Patients who required endoscopic hemostatic intervention had more TEE-related injuries (43% vs 3%,
=0.005), gastric ulcers (35% vs 6%,
=0.018), or ulcers in the first part of the duodenum (29% vs 0%,
=0.006) than those who did not. Intraoperative TEE did not increase the need for endoscopic intervention (71% vs 64%,
=0.435). Intraoperative TEE and the need for endoscopic intervention did not affect length of stay or all-cause mortality. Only one death was associated with gastrointestinal bleeding.

Despite the potential severity of bleeding after cardiovascular surgery, most cases can be managed endoscopically with no increase in hospital stay or mortality.
