RESUMO

BACKGROUND: Aortic dissection (AD) is a serious disease. Previous study, the use of peripheral blood biomarkers to diagnose AD showed strong clinical feasibility, but the possible molecular mechanism is unclear. METHODS: Sera from 79 healthy subjects, 73 patients with well-established AD, and 74 patients with well-established acute myocardial infarction (AMI) were investigated by Liquid Chromatograph-Mass Spectrometer to detect metabolites (AFMK, Glycerophosphocholine, Inosine, SPH). The cell factor expression in the 3 group were detected by Liquid Chip Technology. RESULTS: The serum content trends of 4 metabolic indexes in patients with AMI and AD group were used as the diagnostic models, and the effective diagnosis rate was 97.8%. The diagnosis rate is 89.8% in distinguishing patients with AMI from patients with AD. The expression in serum of the 3 groups showed that there were significant differences in the expression of 23 cytokines. By correlation analysis, it was found that miP-1, IL-7, MIP-1ß, EGF and other cytokines were significantly correlated with the 4 metabolic molecules. CONCLUSIONS: AFMK, Glycerophosphocholine, Inosine, Sphingfungin B (SPH) metabolites are potential biomarkers for AD, and the influence of related metabolic process may be related to the expression of miP-1, IL-7, MIP-1ß, EGF, and other cytokines.

RESUMO

OBJECTIVE: This retrospective study aimed to access the correlations of RENAL, PADUA and NePhRO scores with operative complications, chronic kidney disease (CKD) upstaging, and oncologic outcomes after CT-guided percutaneous Microwave Ablation (MWA) of renal tumors in order to determine their status as independent predictors of outcomes after MWA. This study also aimed to generally evaluate the efficacy of MWA in treating renal tumors. METHODS: From January 2017 to December 2019, 18 patients with 27 renal tumors who had undergone simultaneous biopsy and MWA were recruited in this single-center retrospective study. Data collection included tumor characteristics, procedural protocols, complications, CKD upstaging data, local tumor control data and overall survival. All lesions were evaluated using RENAL, PADUA and NePhRO scores, and further analysis was performed to determine whether the scores were correlated with operative complications, CKD upstaging, local tumor control and overall survival. RESULTS: The minor and major complication rates were 16.7% and 0%, respectively. Two patients with solitary kidney experienced CKD upstaging. Local tumor recurrence was identified in one type of tumor (3.7%) in the first year of follow-up. L. parameter (P = .031), longitudinal (polar) location score (P = .011), Ne. parameter (P = .036), number of kidneys (P = .005), and number of lesions (P = .008), were predictive factors significantly associated with the occurrence of complications. Besides, CKD upstaging was associated with A. parameter (P = .032) and urinary collecting system score (P = .028). RENAL, PADUA, and NePhRO scores were significantly correlated with complications, overall survival, and CKD upstaging, respectively (P < .05). CONCLUSION: CT-guided percutaneous MWA was found to be a valuable alternative in the treatment of renal tumors for selected patients. Furthermore, RENAL, PADUA and NePhRO scores were not independent predictors of outcomes of MWA.

RESUMO

PURPOSE: This study aimed to investigate the feasibility, safety, and efficacy of computed tomography (CT)-guided percutaneous coaxial biopsy combined with microwave ablation (MWA) for the treatment of renal masses. MATERIAL AND METHODS: The clinical data of ten patients (14 tumors) treated with CT-guided percutaneous coaxial biopsy combined with MWA from January 2017 to November 2019 were retrospectively analyzed. The patients were followed up for 2-33 months. The outcomes were evaluated with plain and contrast spiral CT scans. Renal function was assessed using the estimated glomerular filtration rate. RESULTS: No severe MWA-related complication was observed. All the tumors were successfully ablated. There was no imaging evidence of local residual tumor, local tumor recurrence, or disease progression during the follow-up period. CONCLUSIONS: CT-guided percutaneous coaxial biopsy combined with MWA might be an effective option for the diagnosis and treatment of renal masses in selected patients.

RESUMO

PURPOSE: To perform a placebo-controlled trial to evaluate the efficacy and safety of Serenoa repens extract (SRE) for the treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). METHODS: We conducted a double-blind, randomized, placebo-controlled, multicenter, clinical phase 4 study of 221 patients with CP/CPPS across 11 centers. Participants were randomly assigned in a 2:1 ratio to receive SRE or placebo for 12 weeks. The primary efficacy endpoint was the change in total score on the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI). Secondary efficacy endpoints included improvements within each domain of NIH-CPSI, clinical response rate, and International Index of Erectile Function 5 items (IIEF-5). RESULTS: In total, 226 patients were enrolled and randomized between January 2017 and June 2018. Of these 221 patients were included in the intent-to-treat analysis: 148 in the SRE group and 73 patients in the placebo group. Compared to the placebo, SRE led to statistically significant improvements in the NIH-CPSI total score and sub-scores. The significant improvements of NIH-CPSI scores were established after 2 weeks from the first dose, and continued to the end of the treatment. Furthermore, a significantly higher rate of patients achieved a clinical response in the SRE group compared with that in the placebo group (73.0% vs 32.9%, P < 0.0001). Only minor adverse events were observed across the entire study population. CONCLUSIONS: SRE was effective, safe, and clinically superior to placebo for the treatment of CP/CPPS. ChiCTR-IPR-16010196, December 21, 2016 retrospectively registered.

RESUMO

PURPOSE: To evaluate the short-term efficacy and safety of immunotherapy with sintilimab combined with bronchial arterial infusion (BAI) chemotherapy/drug-eluting embolic (DEE) bronchial arterial chemoembolization (BACE) for advanced non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: Ten patients with advanced NSCLC were treated with sintilimab plus BAI/DEE-BACE between December 2019 and November 2020 and retrospectively evaluated. The Response Evaluation Criteria in Solid Tumors version 1.1 was applied to evaluate the treatment response. The local tumor control duration, progression-free survival (PFS), and overall survival (OS) were estimated using the Kaplan-Meier analysis. RESULTS: At 30 days after the last multimodal treatment, complete response, partial response, and stable disease were recorded in 1 (10%), 7 (70%), and 2 (20%) patients, respectively, for an objective response rate of 80% and a disease control rate of 100%. No patient experienced progressive disease. The median duration of local tumor control was 8.0 months (95% CI, 6.2-9.7 months). The median PFS and OS were 11.0 months (95% CI, 6.9-15.1 months) and 8.0 months (95% CI, 5.5-10.5 months), respectively. Two cases of Grade III adverse events related to medications were reported. CONCLUSIONS: Sintilimab combined with BAI/DEE-BACE for patients with advanced NSCLC appears to be safe and feasible. Compared with previous studies on BAI/DEE-BACE, the addition of immunotherapy may improve survival.

RESUMO

PURPOSE: To explore the outcomes of computed tomography‒guided microwave (MW) ablation in patients with cavitary non-small cell lung cancer (NSCLC) and to compare the outcomes of cavitary and noncavitary NSCLC treated with MW ablation. MATERIALS AND METHODS: A total of 317 patients with NSCLC (194 men and 123 women) treated with MW ablation were include: 19 patients with cavitary NSCLC and 298 patients with noncavitary NSCLC. Complications, progression-free survival (PFS), and overall survival (OS) were evaluated and compared between the 2 groups. The Kaplan-Meier method was used to investigate the correlation of cavity and OS in patients with NSCLC. RESULTS: A total of 364 MW ablation procedures were performed. Adenocarcinoma was the predominant histopathological subtype in patients with cavitary NSCLC (73.7%). Cavitary NSCLC had an incidence rate of 57.9% in overall complications, which was significantly higher than that of 34.6% for noncavitary NSCLC (P = .040). In a mean follow-up of 27.2 months ± 11.9, the median PFS and OS for cavitary NSCLC were 9.0 months ± 8.5 and 14.0 months ± 10.8, respectively, and those for noncavitary NSCLC were 13.0 months ± 10.7 and 17.0 months ± 10.9, respectively. There was no significant difference in PFS (P = .180) or OS (P = .133) between cavitary and noncavitary NSCLC. In addition, the local recurrence rates for cavitary and noncavitary NSCLC were 15.8% and 21.5%, respectively, and no significant difference was found (P = .765). The Kaplan-Meier method revealed no association between the cavity and OS in patients with NSCLC treated with MW ablation. CONCLUSIONS: MW ablation was an effective and safe approach for cavitary NSCLC treatment. Compared with noncavitary NSCLC, cavitary NSCLC manifested with more complications but a comparable outcome after MW ablation.

RESUMO

OBJECTIVES: To develop an effective nomogram model for predicting the local progression after computed tomography-guided microwave ablation (MWA) in non-small cell lung cancer (NSCLC) patients. METHODS: NSCLC patients treated with MWA were randomly allocated to either the training cohort or the validation cohort (4:1). The predictors of local progression identified by univariable and multivariable analyses in the training cohort were used to develop a nomogram model. The C-statistic was used to evaluate the predictive accuracy in both the training and validation cohorts. RESULTS: A total of 304 patients (training cohort: n = 250; validation cohort: n = 54) were included in this study. The predictors selected into the nomogram for local progression included the tumor subtypes (odds ratio [OR], 2.494; 95% confidence interval [CI], 1.415-4.396, p = 0.002), vessels ≥3 mm in direct contact with tumor (OR, 2.750; 95% CI, 1.263-5.988; p = 0.011), tumor diameter (OR, 2.252; 95% CI, 1.034-4.903; p = 0.041) and location (OR, 2.442; 95% CI, 1.201-4.965; p = 0.014). The C-statistic showed good predictive performance in both cohorts, with a C-statistic of 0.777 (95% CI, 0.707-0.848) internally and 0.712 (95% CI, 0.570-0.855) externally (training cohort and validation cohort, respectively). The optimal cutoff value for the risk of local progression was 0.39. CONCLUSIONS: Tumor subtypes, vessels ≥3 mm in direct contact with the tumor, tumor diameter and location were predictors of local progression after MWA in NSCLC patients. The nomogram model could effectively predict the risk of local progression after MWA. Patients showing a high risk (>0.39) on the nomogram should be monitored for local progression.

RESUMO

Cryoablation (CA), high-intensity focused ultrasound (HIFU), irreversible electroporation (IRE), and vascular-targeted photodynamic therapy (VTP) have been evaluated as novel strategies for selected patients with prostate cancer (PCa). We aim to determine the current status of literature regarding the clinical outcomes among these minimally invasive therapies. A systematic search of PubMed, EMBASE, and the Cochrane Library for all English literature published from January 2001 to December 2019 was conducted to identify studies evaluating outcomes of CA, HIFU, IRE or VTP on PCa. Proportionality with 95% confidence intervals (CIs) was performed using STATA version 14.0. 56 studies consisting of 7383 participants were found to report data of interest and fulfilled the inclusion criteria in the final meta-analysis. The pooled proportions of positive biopsy after procedure were 20.0%, 24.3%, 24.2%, and 36.2% in CA, HIFU, IRE and VTP, respectively. The pooled proportions of BRFS were 75.7% for CA and 74.4% for HIFU. The pooled proportions of CSS were 96.1%, 98.2%, and 97.9% for CA, HIFU, and IRE, respectively. The pooled proportions of OS were 92.8% for CA and 85.2% for HIFU. The pooled proportions of FFS were 64.7%, 90.4%, and 76.7% for CA, IRE and VTP, respectively. The pooled proportions of MFS were 92.8% for HIFU and 99.1% for IRE. This meta-analysis shows that CA, HIFU, IRE, and VTP are promising therapies for PCa patients with similar clinical outcomes. However, further larger, well-designed randomized controlled trials are required to confirm this assertion.

RESUMO

BACKGROUND: Patient activation is critical in hospitalized older adults preparing for discharge as it enhances their ability to self-care at home. Little is known about how person-centred care and demographic predictors could influence activation in Asian patients. AIMS: To explore patient activation and its predictors in hospitalized older adults in Singapore. METHODS: Multi-centre cross-sectional survey of hospitalized older adults. Multivariable analysis conducted with age, gender, education, socioeconomic status, functional dependency and perception of person-centred care as potential predictors to patient activation. RESULTS: 300 older adults were surveyed, 65% were at the top two levels of activation. Perception of person-centred nursing care was the strongest predictor with the largest effect on patient activation, (ß=0.22, b=3.48, 95% CI:1.70-5.26, p<0.001). Other predictors were age, education, income and independence in care. CONCLUSION: Our study highlights the importance of person-centred nursing care in raising patient activation in hospitalized older adults, enhancing their capacity to self-care.

RESUMO

Skin cleansers and protectants protect skin from incontinent matter to reduce the risk of incontinence-associated dermatitis (IAD), but their effectiveness treating established IAD in the tropics is unknown. We conducted an open-label cluster randomised trial to compare the effectiveness of a combined regimen of (1) specialised skin cleansers with disposable body wipes and (2) either an acrylic terpolymer (T1) or zinc oxide (T2) skin protectant against disposable body wipes and zinc oxide protectant (control) in promoting IAD healing and reducing the risk of deterioration. Eighty-four patients were recruited in a tertiary hospital in Singapore between April 2019 and January 2020 (T1: n = 23; T2: n = 37; Control: n = 24). Although not statistically significant, patients treated with T1 and T2 were 1.5 times as likely to experience IAD healing within seven days compared with the control (P = .66). Healing was more pronounced in participants with skin loss treated with T1 or T2. No treatment was superior in preventing IAD deterioration, the prevalence of which remained small (8%-14%). While skin cleaning and protectants reduced the overall risk of skin deterioration, the addition of skin cleansers enhanced IAD healing within a short period, an important consideration for future research examining IAD treatment in acute care.

RESUMO

The excessive production of inflammatory mediators by vascular endothelial cells (ECs) greatly contributes to the development of atherosclerosis. In this study, we explored the potential effect of lncRNA MALAT1 on endothelial inflammation. First, the EC inflammation model was constructed by treating human umbilical vein ECs (HUVECs) and human coronary artery ECs (HCAECs) with oxidized low-density lipoprotein (ox-LDL), which confirmed the role of MALAT1 in the inflammatory activity. Then MALAT1 was overexpressed in HUVECs and HCAECs, and the levels of inflammatory mediators and nitric oxide (NO) were examined by Western blotting, ELISA, and NO detection assay. The migration ability was confirmed by wound healing assay. The interactions among MALAT1, miR-590, and STAT3 were predicted by bioinformatics analysis and verified by qRT-PCR, Western blotting, or dual-luciferase reporter assay. MALAT1 was upregulated in ECs treated with ox-LDL, and knockdown of MALAT1 significantly inhibited ox-LDL-induced inflammation. MALAT1 overexpression potentiated the inflammatory activities of ECs, including enhanced production of inflammatory cytokines (IL-6, IL-8, and TNF-α) and adhesion molecules (VCAM1 and ICAM1), and decreased NO level and cell migratory ability. Mechanistically, MALAT1 could directly downregulate miR-590, and miR-590 could bind to the 3'-UTR of STAT3 to repress its expression. Additionally, overexpression of MALAT1-mediated inflammation was largely abrogated by the concomitant overexpression of miR-590. miR-590 knockdown activated the inflammatory response, which was reversed by STAT3 inhibition. Thus, MALAT1 serves as a proinflammatory lncRNA in ECs through regulating the miR-590/STAT3 axis, suggesting that MALAT1 may be a promising therapeutic target during the treatment of atherosclerosis.

RESUMO

BACKGROUND: The value of pelvic lymphadenectomy during radical prostatectomy (RP) remains controversial. This study aims to test the effects of the number of removed lymph nodes (RLN), positive nodes (pLN), and pLN ratio (pLNR) on cancer-specific survival (CSS) in patients with node-positive prostate cancer (PCa). METHODS: A total of 2458 patients with a greater than 5% probability of lymph node invasion according to the updated Briganti nomogram who harboured pathologically confirmed positive nodes in the Surveillance, Epidemiology, and End Results database between 2004 and 2015 were identified. Multivariable Cox regression with forward stepwise selection was performed to identify independent risk factors for CSS. Maximally selected rank statistics were used to determine the most informative cut-off value for pLN and pLNR. RESULTS: The median pLN counts and RLN in the study were two (interquartile range [IQR] 1- 3) and 18 (IQR 15-23), respectively. The RLN counts could not predict CSS, while the higher pLN and pLNR were associated with worse CSS (hazard ratio [HR], 1.11; p < 0.001 and HR, 1.01; p < 0.001, respectively). Patients with ≤ 2 pLN or pLNR ≤ 20% had significantly better CSS than those with pLN > 2 or pLNR > 20% (HR, 1.38 (1.08-1.77); p = 0.009; HR, 1.77 (1.41-2.22); p < 0.001, respectively). CONCLUSIONS: In patients with node-positive PCa, pelvic lymphadenectomy provides important information for staging, prognosis, and guiding after RP therapy; however, it does not play a therapeutic role. The pLN counts and pLNR were independent predictors of CSS.

RESUMO

BACKGROUND: Strong evidence comparing effectiveness between nephron-sparing intervention (NSI) and active surveillance (AS) is lacking. Thus, we aim to compare the outcomes of survival, including cancer-specific survival (CSS), overall survival (OS), and cardiovascular-specific survival (CVSS), in patients with renal masses who underwent NSI or AS. METHODS: A systematic literature search of PubMed, Web of Science, and EMBASE was performed for citations published prior to September 2018 that described NSI, partial nephrectomy and thermal ablation included, and AS for patients with renal masses and a standard meta-analysis on survival outcomes was then conducted. RESULTS: The meta-analysis included seven studies containing 5809 patients. The results comparing NSI with AS were as follows: CSS (hazard ratio (HR) = 0.64, 95% confidence interval (CI): 0.46-0.89, P < 0.001), OS (HR = 0.46, 95%CI: 0.39-0.53, P < 0.001), and CVSS (HR = 0.37, 95%CI: 0.24-0.57, P < 0.001). CONCLUSIONS: This systematic review and meta-analysis indicates that NSI is associated with better OS, CSS and CVSS when compared with AS for patients with renal masses. Further better prospective cohort studies are needed to make definitive statements about these different treatment methods.

RESUMO

OBJECTIVES: To investigate whether ureteroscopy (URS) before radical nephroureterectomy (RNU) for upper tract urothelial carcinomas (UTUCs) has an impact on oncological outcomes. PATIENTS AND METHODS: We performed a systematic literature search of PubMed, Web of Science, and EMBASE for citations published prior to September 2017 that described URS performed on patients with UTUC and conducted a standard meta-analysis on survival outcomes. RESULTS: Our meta-analysis included eight eligible studies containing 3975 patients. The results were as follows: cancer-specific survival (CSS; hazard ratio [HR] 0.76, 95% confidence interval [CI] 0.59-0.99; P = 0.04), overall survival (OS; HR 0.76, 95% CI 0.48-1.21; P = 0.24), recurrence-free survival (RFS; HR 0.89, 95% CI 0.69-1.14; P = 0.37), metastasis-free survival (MFS; HR 1.06, 95% CI 0.82-1.36; P = 0.66), and intravesical recurrence-free survival (IRFS; HR 1.51, 95% CI 1.29-1.77; P < 0.001). When excluding previous bladder tumour history, the result for IRFS was a HR of 1.81 (95% CI 1.53-2.13; P < 0.001). CONCLUSIONS: This meta-analysis indicated that URS before RNU did not have a negative impact on CSS, OS, RFS, or MFS in patients with UTUC. However, patients were at higher risk of intravesical recurrence after RNU when they had undergone URS before RNU. Further studies are needed to assess the effects of post-URS intravesical chemotherapy on intravesical recurrence.

RESUMO

Aggregation-induced emission has been extensively found in organic compounds and metal complexes. In contrast, aggregation-induced electrochemiluminescence (AI-ECL) is rarely observed. Here, we employ two tridentate ligands [2,2':6',2″-terpyridine (tpy) and 1,3-bis(1 H-benzimidazol-2-yl)benzene (bbbiH3)] to construct a cyclometalated iridium(III) complex, [Ir(tpy)(bbbi)] (1), showing strong AI-ECL. Its crystal structure indicates that neighboring [Ir(tpy)(bbbi)] molecules are connected through both π-π-stacking interactions and hydrogen bonds. These supramolecular interactions can facilitate the self-assembly of complex 1 into nanoparticles in an aqueous solution. The efficient restriction of molecular vibration in these nanoparticles leads to strong AI-ECL emission of complex 1. In a dimethyl sulfoxide-water (H2O) mixture with a gradual increase in the H2O fraction from 20% to 98%, complex 1 showed a ∼39-fold increase in the electrochemiluminescence (ECL) intensity, which was ∼4.04 times as high as that of [Ru(bpy)3]2+ under the same experimental conditions. Moreover, the binding of bovine serum albumin to the nanoparticles of complex 1 can improve the ECL emission of this complex, facilitating the understanding of the mechanism of AI-ECL for future applications.

RESUMO

MiR-15a is likely to be associated with autoimmunity. Here, we aimed to examine the expression of miR-15 cluster in PBMCs from myasthenia gravis (MG) patients and investigate the potential roles of miR-15a in MG. We found that the expression of all miR-15 cluster was decreased in MG, furthermore, miR-15a levels in ocular MG (oMG) were much lower, while CXCL10 production was increased in MG. We display that CXCL10 was a functional target gene of miR-15a in MG. Increasing miR-15a expression could reduce CXCL10 expression and alleviate the abnormal T cells activation in immune response, while decreasing miR-15a expression could activate immune response abnormally. Moreover, miR-15a expression was significantly decreased after stimulation, and prednisone treatment could upregulate miR-15a expression in steroid-responsive MG patients. Take together, our data suggest that decreased miR-15a expression facilitates proinflammatory cytokines production and contributes to immune response at least in part via regulating CXCL10 expression in MG.

RESUMO

Daphne genkwa Sieb.et Zucc. is a well-known medicinal plant. This study was designed to investigate the anticancer effects of total flavonoids in D. genkwa (TFDG) in vitro and in vivo. HT-29 and SW-480 human colorectal cancer cells were cultured to investigate the anticancer activity of TFDG. In addition, the Apc(Min/+) mouse model was applied in the in vivo experiment. Results of the cell experiment revealed that TFDG possessed significant inhibitory effects on HT-29 and SW-480 human colorectal cancer cells (both p < 0.01). Furthermore, our in vivo data showed that after treatment with TFDG, there was a significant increase in life span (both p < 0.01) and tumor numbers were reduced in the colon (both p < 0.01), which was supported by the data of tumor distribution, body weight changes and organ index. Our results also indicated that expressions of interleukin (IL)-1α, IL-1ß, IL-6, granulocyte colony-stimulating factor and granulocyte-macrophage colony-stimulating factor in gut tissue were downregulated by treatments of TFDG, and immunity cytokine secretions in the serum were regulated after oral administration of TFDG. Taken together, these findings suggested that TFDG has a potential clinical utility in colorectal cancer therapeutics, and TFDG's action is likely linked to its ability to regulate immune function and inhibit the production of inflammatory cytokines.

RESUMO

BACKGROUND: To assess the performance of risk scores in predicting symptomatic intracranial hemorrhage (SICH) after intravenous thrombolysis (IVT). METHODS: A multicenter prospective study was performed in 811 patients who underwent IVT with standard-dose recombinant tissue plasminogen activator within 4.5 hours of acute ischemic stroke (AIS) onset in 67 stroke centers involved in the Thrombolysis Implementation and Monitor of acute ischemic Stroke in China program from May 2007 to April 2012. SEDAN (blood sugar, early infarct signs, [hyper]dense cerebral artery sign, age) score, Safe Implementation of Thrombolysis in Stroke (SITS)-SICH score, Glucose Race Age Sex Pressure Stroke Severity (GRASPS) score, Multicenter Stroke Survey (MSS) score, and Stroke Prognostication using Age and National Institutes of Health Stroke Scale (SPAN)-100 index were calculated in selected patients, and their predictive performance for SICH was compared according to the National Institute of Neurological Disorders and Stroke (NINDS), Safe Implementation of Thrombolysis in Stroke-Monitoring Study (SITS-MOST), and European Cooperative Acute Stroke Study (ECASS)-II criteria. RESULTS: For predicting the risk of SICH (NINDS definition) after IVT, the area under the receiver operating characteristic (ROC) curve of MSS score was the highest (.71, P < .0001). For predicting the risk of SICH (SITS-MOST definition) after IVT, the area under the ROC curve of GRASPS score was the highest (.73, P = .005). For predicting SICH (ECASS-II definition) after IVT, the area under the ROC curve of MSS score was the highest (.73, P < .0001). CONCLUSIONS: SITS-SICH, GRASPS, and MSS scores predicted the risk of SICH after IVT in patients with AIS, but only the latter 2 were better in the Chinese population. MSS score had the best predictive performance for SICH using NINDS and ECASS-II definitions, whereas GRASPS score was the best for SICH using the SITS-MOST definition.

RESUMO

BACKGROUND: There are few large-scale analyses comparing local tumor destruction (LTD) or local tumor enucleation/excision (LTE) relative to partial nephrectomy (PN) for patients with T1a renal masses in terms of cancer-specific survival (CSS) and overall survival (OS). We aimed to compare CSS and OS after LTD versus LTE versus PN. MATERIALS AND METHODS: Within the Surveillance, Epidemiology, and End Results (SEER) database (2000-2019), we identified patients with clinical T1a renal masses and histologically confirmed kidney cancer treated with LTD, LTE or PN. After 1:1 ratio propensity score matching (PSM), comparisons between the groups were conducted. Kaplan-Meier analysis and log-rank tests were used to compare survival in the matched population. RESULTS: In the overall cohort of 3717 LTD patients versus 1993 LTE patients versus 26935 PN patients, 77.3% of LTD-treated patients and 74.4% of LTE-treated patients were over 60 years old, while only 50.3% of PN-treated patients were over 60 years old. PN was more strongly associated with CSS (hazard ratio (HR)=1.276, P<0.001) and OS (HR=1.112, P<0.001)) than was LTD, while PN was less strongly associated with CSS (HR=1.040, P=0.230) and OS (HR=0.888, P=0.002) than was LTE, not only in the PSM cohort but also in the subgroups of patients with a tumor size ≤3 cm and patients with a tumor size of 3.1-4 cm. CONCLUSIONS: In clinical T1a solid renal mass patients, LTD was associated with lower CSS and OS than LTE and PN, while LTE demonstrated noninferior CSS and superior OS to PN regardless of tumor size.

RESUMO

Arabinoxylan (AX) is a potential natural food additive that can enhance the textural properties of food. However, the addition of ascorbic acid (AA) can easily lead to a decrease in the viscosity of AX, which poses a challenge in the development of AX-rich foods. Therefore, the purpose of this study is to elucidate the mechanisms behind the reduction in AX viscosity in the presence of AA. The results indicated that AA could reduce the apparent viscosity and molecular weight of AX without significantly affecting the monosaccharide composition, suggesting a potential mechanism related to the cleavage of AX glycosidic bonds. Interestingly, free radicals were present in the reaction system, and the generation of free radicals under different conditions was consistent with the reduction in apparent viscosity of AX. Furthermore, the reduction in AX apparent viscosity by AA was influenced by various factors including AA concentration, reaction time, temperature, pH, and metal ions. These findings suggested that the mechanism of AX degradation may be due to AA-induced free radical generation, leading to non-selective attacks on glycosidic bonds. Therefore, this study revealed that the potential mechanism behind the reduction in AX viscosity induced by AA involved the generation of ascorbic acid radicals.
