RESUMO

BACKGROUND: The association between hypothyroidism and stroke remains controversial and the association between hypothyroidism and stroke subtypes has not been satisfactorily researched. This study aimed to explore the causal effect of hypothyroidism on the risk of stroke and its subtypes by Mendelian randomization (MR) analysis. METHODS: Single nucleotide polymorphisms (SNPs) were selected from published genome-wide association studies (GWAS) meta-analysis as instrumental variables (IVs) for hypothyroidism. As outcomes, summary GWAS data for stroke and its subtypes were obtained from two other large GWAS meta-analyses, including any stroke (AS), any ischemic stroke (AIS), large vessel stroke (LAS), cardiogenic embolic stroke (CES), small vessel stroke (SVS), and intracranial hemorrhage (ICH). Univariate Mendelian randomization (UVMR) and multivariate Mendelian randomization (MVMR) were used to assess the causal effect of hypothyroidism on stroke and its subtypes. RESULTS: In UVMR, genetically predicted hypothyroidism was significantly associated with LAS (OR = 1.14, 95CI = 1.02-1.27) and SVS (OR = 1.14, 95CI = 1.04-1.25), but not with AS, AIS, CES, and ICH. The results of the MVMR showed that after adjusting for smoking, alcohol consumption, hypertension, diabetes, low-density lipoprotein cholesterol (LDL-c), and body mass index (BMI), the causal association between hypothyroidism and SVS remained significant, while the association between hypothyroidism and LAS became nonsignificant. CONCLUSION: Hypothyroidism is causally associated with risk for LAS and SVS, but not for other stroke subtypes. Hypothyroidism may be an independent risk factor for SVS, and vascular risk factors play an important role in hypothyroidism causing LAS.

RESUMO

OBJECTIVE: To determine whether proactive molecular risk classifier for endometrial cancer (ProMisE) could be used to assess the prognosis of patients with atypical endometrial hyperplasia (AEH) or early-stage endometrial cancer (EC) treated with levonorgestrel-releasing intrauterine system (LNG-IUS). METHODS: A retrospective cohort study was conducted among 93 AEH or early-stage EC patients who received LNG-IUS to preserve fertility . By immunohistochemistry and gene sequencing, 4 subtypes of ProMisE were identified (p53 wild type [p53 wt], mismatch repair-deficient [MMRd], p53-abnormal, and POLE-mutated). The primary outcome was the time to complete response (CR) after LNG-IUS therapy. Secondary outcomes included the recurrence rate after CR and success rate of conception. RESULTS: Among the 93 patients, 15 (16.1%) were classified as MMRd, 6 (6.5%) as POLE-mutated, 5 (5.4%) as p53-abnormal, and 67 (72.0%) as p53 wt. Comparison of serum cancer antigen 125, family history of tumor, and positive rates of programmed cell death 1 ligand 1 protein and Ki67 protein in 4 groups showed statistically significant differences (p<0.05). Patients with the p53-abnormal subtype had the lowest overall CR rate (40%) and the highest recurrence rate (2/2). Patients with POLE-mutated subtype had the best prognosis, and all 6 patients achieved CR. When patients achieved complete remission, assisted reproductive technology was more likely to help them conceive than natural conception (p<0.05). CONCLUSION: Patients with early-stage EC or AEH who are more likely to benefit from fertility-sparing treatment can be identified using ProMisE classifier. Patients with POLE-mutated are suitable for fertility-sparing treatment with LNG-IUS.

RESUMO

BACKGROUND: Numerous research works have investigated the association between tea consumption and the risk of acute cerebrovascular events; however, the results are inconsistent. OBJECTIVES: We used Mendelian randomization (MR) to evaluate the causal association between tea intake and several acute cerebrovascular events, including any ischemic stroke, large atherosclerotic stroke (LAS), cardiogenic embolic stroke (CES), small vessel stroke (SVS), intracranial hemorrhage (ICH), and subarachnoid hemorrhage (SAH). METHODS: We obtained summary genome-wide association study (GWAS) data on tea intake and acute cerebrovascular events in populations of European ancestry. The GWAS on tea intake is derived from the UK Biobank, where we have chosen single-nucleotide polymorphisms (SNPs) closely associated with it as instrumental variables. We also obtained summary data on ischemic stroke from a GWAS meta-analysis, as well as summary data on ICH and SAH from the FinnGen study. We first explored the causal association between tea intake and several acute cerebrovascular events using univariate Mendelian randomization (UVMR), and then further assessed the causal association between tea intake and SVS using multivariate Mendelian randomization (MVMR) corrected for multiple confounders. RESULTS: In UVMR, genetically predicted increases in tea intake were linked to a lower risk of SVS (OR: 0.58; 95% CI: 0.39, 0.86). There was no causal association between tea intake and the risk of other acute cerebrovascular events. In the MVMR, our results show that there was still a significant causal association between drinking tea and SVS, after adjusting body mass index, total cholesterol, low-density lipoprotein cholesterol, diabetes, hypertension, smoking, and alcohol consumption. CONCLUSION: This MR study provides new genetic evidence that increased tea intake reduces the risk of SVS in the European population. However, possibly because of limited statistical power, the study did not find that tea consumption reduced the risk of several other acute cerebrovascular events.

RESUMO

Currently, there is an inherent contradiction between the multifunctionality and excellent biocompatibility of anticancer drug nanocarriers, which limits their application. Therefore, to overcome this limitation, we aimed to develop a biocompatible drug delivery system for the treatment of hepatocellular carcinoma (HCC). In this study, we employed poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) as the fundamental framework of the nanocarrier and utilized the emulsion solvent evaporation method to fabricate nanoparticles loaded with paclitaxel (PTX), known as PTX-PHBV NPs. To enhance the tumor-targeting capability, a dopamine self-polymerization strategy was employed to form a pH-sensitive coating on the surface of the nanoparticles. Then, folic acid (FA)-targeting HCC was conjugated to the nanoparticles with a polydopamine (PDA) coating by using the Michael addition reaction, resulting in the formation of HCC-targeted nanoparticles (PTX-PHBV@PDA-FA NPs). The PTX-PHBV@PDA-FA NPs were characterized and analyzed by using dynamic light scattering, scanning electron microscopy, fourier-transform infrared spectroscopy, X-ray diffraction, differential scanning calorimetry, and thermogravimetric analysis. Encouragingly, PTX-PHBV@PDA-FA NPs exhibited remarkable anticancer efficacy in an HCC xenograft mouse model. Furthermore, compared to raw PTX, PTX-PHBV@PDA-FA NPs showed less toxicity in vivo. In conclusion, these results demonstrate the potential of PTX-PHBV@PDA-FA NPs for HCC treatment and biocompatibility.

RESUMO

Objective: The causal relationship between Rheumatoid arthritis (RA) and hypothyroidism/hyperthyroidism remains controversial due to the limitations of conventional observational research, such as confounding variables and reverse causality. We aimed to examine the potential causal relationship between RA and hypothyroidism/hyperthyroidism using Mendelian randomization (MR). Method: We conducted a bidirectional two-sample univariable analysis to investigate the potential causal relationship between hypothyroidism/hyperthyroidism and RA. Furthermore, we performed a multivariate analysis to account for the impact of body mass index (BMI), smoking quantity, and alcohol intake frequency. Results: The univariable analysis indicated that RA has a causative influence on hypothyroidism (odds ratio [OR]=1.07, 95% confidence interval [CI]=1.01-1.14, P=0.02) and hyperthyroidism (OR=1.32, 95% CI=1.15-1.52, P<0.001). When hypothyroidism/hyperthyroidism was considered as an exposure variable, we only observed a causal relationship between hypothyroidism (OR=1.21, 95% CI=1.05-1.40, P=0.01) and RA, whereas no such connection was found between hyperthyroidism (OR=0.91, 95% CI=0.83-1.01, P=0.07) and RA. In the multivariate MR analyses, after separately and jointly adjusting for the effects of daily smoking quantity, alcohol intake frequency, and BMI, the causal impact of RA on hypothyroidism/hyperthyroidism and hypothyroidism on RA remained robust. However, there is no evidence to suggest a causal effect of hyperthyroidism on the risk of RA (P >0.05). Conclusion: Univariate and multivariate MR analyses have validated the causal association between RA and hypothyroidism/hyperthyroidism. Hypothyroidism confirmed a causal relationship with RA when employed as an exposure variable, whereas no such relationship was found between hyperthyroidism and RA.

RESUMO

Cell division cycle 42 (CDC42) regulates immune escape, which predicts immune checkpoint inhibitor (ICI) treatment response in several types of cancer. The present study aimed to evaluate the potential of serum CDC42 in predicting the ICI treatment outcome in patients with advanced cervical cancer. A total of 46 patients with advanced cervical cancer who received ICI treatment with or without antiangiogenic agents were enrolled. Serum CDC42 was detected in all patients before treatment (baseline) and following two treatment cycles by enzyme-linked immunosorbent assay. CDC42 at baseline was elevated in patients with target lesion size ≥5 cm (P=0.020), pelvis metastasis (P=0.031) and lung metastasis (P=0.043). Following treatment, the objective response rate (ORR) and disease control rate (DCR) were 30.4 and 78.3%, respectively. Meanwhile, the median progression-free survival (PFS) and overall survival (OS) were 5.8 and 13.1 months. CDC42 at baseline was decreased in patients achieving ORR (P=0.042) but not DCR (P=0.055). PFS (P=0.006) and OS (P=0.019) were decreased in patients with baseline CDC42 ≥600 pg/ml. After two treatment cycles, CDC42 was generally reduced (P<0.001). CDC42 following two treatment cycles was more significantly decreased in patients with ORR (P=0.032) and DCR (P=0.019). Multivariate Cox's regression analysis showed that CDC42 ≥600 pg/ml following two treatment cycles was associated with the shorter PFS (P=0.022, hazard ratio=2.469) and OS (P=0.013, hazard ratio=4.166). Serum CDC42 was reduced after treatment; high expression following treatment reflected a lower possibility of achieving treatment response and poorer survival in patients with advanced cervical cancer.

RESUMO

PURPOSE: This study aimed to evaluate the clinical utility of fecal calprotectin (FC) levels during the necrotizing enterocolitis (NEC) episode to predict the onset of post-NEC intestinal stricture. METHODS: The medical records of patients with NEC treated from April 2020 to April 2022 were recorded for this study. FC was quantified at the acute phase of NEC. FC levels were compared in patients with or without intestinal stricture. Receiver operating characteristics (ROC) analysis was constructed to determine optimal cut-offs of FC for post-NEC intestinal stricture. RESULTS: A total of 50 infants with NEC were enrolled in this study and 14 (28%) of them eventually developed intestinal stricture. All children with intestinal stricture underwent one-stage surgery and all made it through the follow-up period alive. The median FC level was 1237.55 (741.25, 1378.80) ug/g in patients with intestinal stricture and it was significantly higher than that in the non-stricture group [158.30 (76.23, 349.13) ug/g, P < 0.001]. FC had good diagnostic accuracy for predicting intestinal stricture, according to ROC curve analysis, with an AUC area of 0.911. At an optimal cut-off value of 664.2 ug/g, sensitivity and specificity were 85.71% and 91.67%, respectively. CONCLUSION: As a non-invasive parameter, FC has excellent efficacy and accuracy in predicting post-NEC intestinal stricture. Increased FC levels at the acute phase of NEC were associated with the development of intestinal stricture.

RESUMO

Hypoxia is characteristic of the ovarian tumor (OC) microenvironment and profoundly affects tumorigenesis and therapeutic response. Long noncoding RNAs (lncRNAs) play various roles in tumor progression; however, the characteristics of lncRNAs in pathological responses of the OC microenvironment are not entirely understood. Through high-throughput sequencing, lncRNA expression in hypoxia (1% O2 ) and normoxia (21% O2 ) SKOV3 cells was explored and analyzed. The 5'- and 3'-rapid amplification of complementary DNA ends was used to detect the full length of the novel HIF1A-AS3 transcript. Real-time quantitative polymerase chain reaction was used to assess HIF1A-AS3 expression in OC cells and tissues. In vitro and in vivo evaluations of the biological functions of hypoxic HIF1A-AS3 were conducted. To clarify the underlying mechanisms of HIF1A-AS3 in hypoxic OC, a dual-luciferase assay, chromatin immunoprecipitation, RNA pull-down, RNA immunoprecipitation, and RNA-sequencing were used. We used high-throughput sequencing to investigate a novel lncRNA, HIF1A-AS3, as a hypoxic candidate significantly elevated in OC cells/tissues. HIF1A-AS3 was predominantly localized in the nucleus and promoted in vitro and in vivo OC growth and tumorigenesis. Hypoxia-inducible factor 1α bound to hypoxia response elements in the HIF1A-AS3 promoter region and stimulated its expression in hypoxia. Under hypoxia, HIF1A-AS3 directly integrated with Y-Box binding protein 1 and inhibited its ability to bind to the promoters of p21 and AJAP1 to repress their transcriptional activity, thereby promoting hypoxic OC progression. Our results revealed the crucial role and mechanism of the novel hypoxic HIF1A-AS3 in the oncogenesis of OC. The novel HIF1A-AS3 could be a crucial biomarker and therapeutic target for future OC treatments.

RESUMO

Objective: Acyl-CoA thioesterase 13 (ACOT13) encodes a member of the thioesterase superfamily. It has not been reported in ovarian cancer. This research aimed at evaluating the expression and prognostic value of ACOT13 in ovarian serous cystadenocarcinoma (OSC). Methods: We extracted and analyzed TCGA, GEPIA, THPA, GTEx, miRWalk, and GDSC databases to investigate the potential carcinogenic mechanism of ACOT13 in OSC, including the correlation of ACOT13 with prognosis, immune checkpoint, tumor mutational burden (TMB), and 50% inhibition concentration (IC50) score. The incidence of endpoint events was compared with Kaplan-Meier survival analysis. Independent prognostic factors for OSC were evaluated with univariate and multivariate Cox regression analyses, and a nomogram was established. Results: The expression of ACOT13 was increased in OSC and correlated with tumor stage, with higher expression in stages I and II than in stages III and IV. Besides, it was observed that low expression of ACOT13 is correlated with poor overall survival (OS), progression-free survival (PFS), and disease-specific survival (DSS) in patients with OSC. There was a positive correlation between ACOT13 expression and immune checkpoint sialic acid-binding Ig-like lectin (SIGLEC) 15 and TMB. Patients with low ACOT13 expression had higher cisplatin IC50 scores. Conclusion: ACOT13 is an independent prognostic factor and a promising clinical target for OSC. In the future, the carcinogenic mechanism and clinical application value of ACOT13 in ovarian cancer need to be further studied.

RESUMO

Objective: Investigating the association between inflammatory cytokines and hypothyroidism remains challenging due to limitations in traditional observational studies. In this study, we employed Mendelian randomization (MR) to assess the causal relationship between 41 inflammatory cytokines and hypothyroidism. Method: Inflammatory cytokines in 30,155 individuals of European ancestry with hypothyroidism and in a GWAS summary containing 8,293 healthy participants were included in the study for bidirectional two-sample MR analysis. We utilized inverse variance weighting (IVW), weighted median (WM), and Mendelian randomization-Egger (MR-Egger) methods. Multiple sensitivity analyses, including MR-Egger intercept test, leave-one-out analysis, funnel plot, scatterplot, and MR-PRESSO, were applied to evaluate assumptions. Results: We found evidence of a causal effect of IL-7 and macrophage inflammatory protein-1ß (MIP-1ß) on the risk of hypothyroidism, and a causal effect of hypothyroidism on several cytokines, including granulocyte colony-stimulating factor (G-CSF), IL-13, IL-16, IL-2rα, IL-6, IL-7, IL-9, interferon-γ-inducible protein 10 (IP10), monokine induced by interferon (IFN)-γ (MIG), macrophage inflammatory protein-1ß (MIP-1ß), stem cell growth factors-ß (SCGF-ß), stromal cell derived factor-1α (SDF-1α), and tumor necrosis factor-α (TNF-α). Conclusion: Our study suggests that IL-7 and MIP-1ß may play a role in the pathogenesis of hypothyroidism, and that hypothyroidism may induce a systemic inflammatory response involving multiple cytokines. These findings may have implications for the prevention and treatment of hypothyroidism and its complications. However, further experimental studies are needed to validate the causal relationships and the potential of these cytokines as drug targets.

RESUMO

OBJECTIVES: The aim of this study was to identify predictors for enteral autonomy and intestinal failure (IF)-related complications and evaluate the outcomes of a multi-center pediatric cohort in China. METHODS: The medical records of pediatric patients with IF treated at four medical centers in China from January 1, 2012 to November 31, 2020 were retrospectively reviewed. Enteral autonomy was defined as sustained growth and cessation of parenteral nutrition for >90 days. Multivariate logistic regression analysis was used to identify factors predictive of enteral autonomy and the risk factors of complications, such as IF-associated liver disease (IFALD) and catheter-related bloodstream infection (CRBSI). RESULTS: The study cohort of 92 pediatric patients with IF included 71 (77%) who underwent surgery and 21 (23%) who received non-surgical treatment. Eventually, 63 (68.5%) patients achieved enteral autonomy by the end of the follow-up period. Multivariate logistic regression analysis indicated that longer duration of parenteral nutrition (PN), sepsis, and non-breastfeeding were risk factors for enteral autonomy. When considering the detailed intraoperative data, the presence of an ileocecal valve (ICV) and greater residual small bowel (RSB) length were reaffirmed as predictors of achieving enteral autonomy. Medium/long-chain (MCT/LCT) lipids or sepsis were identified as negative predictors for IFALD. Univariate analysis revealed that the use of MCT/LCT lipids was associated with a greater likelihood of CRBSI. CONCLUSION: In this cohort, enteral autonomy was achieved at a percentage of 68.5%, and the risk factors for not achieving enteral autonomy were a longer duration of PN, sepsis, and non-breastfeeding. The presence of an ICV and a greater RSB length were important predictors of achieving enteral autonomy.

RESUMO

OBJECTIVE: There is little evidence to support a correlation between abdominal surgery and acute cerebellar ataxia (ACA). We reviewed the records of children with ACA treated at our institution to analyze risk factors for ACA. METHODS: Clinical data of 442 children with ACA treated at Children's Hospital of Nanjing Medical University between November 2015 and June 2019 were retrospectively analyzed. Univariate and multivariate analyses were performed to determine risk factors for the occurrence and recurrence of ACA. RESULTS: In total, 442 children with ACA were included in this study. Multivariate logistic regression analysis showed age (p = 0.009), infection (p < 0.001), vaccination (p < 0.001), head trauma (p < 0.001), intussusception surgery (IS) (p < 0.001), operation for indirect inguinal hernia (p < 0.001), and operation for congenital gastrointestinal malformation (p < 0.001) were independent risk factors for ACA occurrence. Univariate analysis showed that only IS (p < 0.001) was associated with ACA recurrence. CONCLUSIONS: Surgeons should be aware that age, infection, vaccination, head trauma, and history of abdominal surgery are associated with ACA, while IS is a risk factor for ACA recurrence.

RESUMO

Penfluridol, a commonly used antipsychotic agent in a clinical setting, exhibits potential anticancer properties against various human malignancies. Here, we investigated the effect of penfluridol on the biological behavior of colorectal cancer (CRC) cells. Cell viability and clonogenic potential were detected by the cell counting kit-8 and colony formation assay. The cell apoptosis and cell cycle distribution were quantified through flow cytometry. Caspase-3 activity, glucose consumption, lactate production, and intracellular ATP levels were evaluated using the corresponding commercial detection kits. The protein levels of related genes were detected through western blotting. Mitochondrial membrane potential was detected using JC-1 staining. A CRC xenograft tumor model was used to validate the antitumor activity of penfluridol in vivo. Penfluridol reduced cell survival and promoted apoptotic cell death effectively through the mitochondria-mediated intrinsic pathway in a dose-dependent manner. Furthermore, the process of glycolysis in HCT-116 and HT-29 cells was inhibited upon penfluridol treatment, as evidenced by the decrease in glucose consumption, lactate production, and intracellular ATP levels. Further mechanistic studies revealed that penfluridol influenced cell apoptosis and glycolysis in CRC cells by downregulating hexokinase-2 (HK-2). The proapoptotic effect and glycolytic inhibition-induced by penfluridol were effectively reversed by HK-2 overexpression. Consistent with in vitro results, penfluridol could also suppress tumor growth and trigger apoptosis in vivo. Penfluridol triggers mitochondrial-mediated apoptosis and induces glycolysis inhibition via modulating HK-2 in CRC and provides a theoretical basis to support penfluridol as a repurposed drug for CRC patients.

RESUMO

AIM: To assess the efficacy and safety of polyethylene glycol loxenatide (PEX168), a new glucagon-like peptide-1 receptor agonist, as an add-on to metformin therapy in Chinese patients with type 2 diabetes (T2D). MATERIALS AND METHODS: This was a multicentre, randomized, double-blind, placebo-controlled phase 3b trial. After metformin monotherapy (≥1500 mg/day) for 8 weeks or more, patients with uncontrolled T2D (HbA1c of 7.0%-10.5%) from 44 sites were randomized (1:1:1) to metformin + placebo, metformin + PEX168 100 µg, and metformin + PEX168 200 µg. The core treatment period lasted for 24 weeks, followed by a 28-week extension period. The primary endpoint was the change in HbA1c levels at week 24. The main secondary endpoint was the proportion of patients with an HbA1c of less than 7.0% at week 24. RESULTS: The least-square mean (standard error) change in HbA1c levels was significantly greater (P < .001 for superiority) in the PEX168 groups (-1.16% [0.08%] and -1.14% [0.08%] with 100 and 200 µg, respectively) than in the placebo group (0.35% [0.08%]). The proportion of patients with an HbA1c of less than 7.0% at week 24 was significantly higher in the PEX168 100 µg (37.4%) and PEX168 200 µg (40.6%) groups than in the placebo group (16.8%; both P < .001). The gastrointestinal reactions were mild; the risks of hypoglycaemia and weight gain did not increase. Anti-PEX168 antibodies were noted in less than 2% of patients. No treatment-emergent serious adverse events occurred. CONCLUSION: The subcutaneous injection of PEX168 once a week can effectively, continuously and safely improve HbA1c levels in patients with T2D when combined with metformin.

RESUMO

Mutation in the tumor suppressor gene p53 is the most frequent molecular defect in endometrial carcinoma (EC). Recently, CP-31398, a p53-stabilizing compound, has been indicated to possess the ability to alter the expression of non-p53 target genes in addition to p53 downstream genes in tumor cells. Herein, we explore the alternative mechanisms underlying the restoration of EC tumor suppressor function in mutant p53 by CP-31398. A p53-mutated EC cell was constructed in AN3CA cells with restored or partial loss of Slug using lentiviral vectors, followed by treatment with 25 µM CP-31398. A p53-independent mechanism of CP-31398 was confirmed by the interaction between mouse double minute 2 homolog (MDM2) and Slug AN3CA cells treated with IWR-1 (inhibitor of Wnt response 1). Furthermore, the AN3CA cells were treated with short hairpin RNA against Slug, Wnt-specific activators (LiCl) or inhibitors (XAV-939) followed by CP-31398 treatment. Moreover, AN3CA cell proliferation and apoptosis were examined. A tumorigenicity assay was conducted in nude mice. CP-31398 could promote the apoptosis of p53-mutated EC cells, while Slug reversed this effect. Slug ubiquitination was found to occur via binding of Slug to MDM2 in AN3CA cells. We found that CP-31398 increased the GSK-3ß, p-Slug, Puma, Wtp53, and Bax expressions whereas Wnt, Mtp-53, Slug, Bcl-2, and Ki-67 expressions were decreased. However, these findings were reversed following the activation of the Wnt pathway and overexpression of Slug. Finally, the in vivo experimental evidence confirmed that CP-31398 with depleted Slug suppressed tumor growth by downregulating the Slug. Collectively, CP-31398-regulated Slug downregulation represses the p53-mutated EC via the p53/Wnt/Puma pathway.

RESUMO

OBJECTIVE: Neoadjuvant chemotherapy (NACT) for the treatment of epithelial ovarian cancer (EOC) has remained controversial. This meta-analysis was performed to systematically assess the efficacy and safety of NACT versus primary debulking surgery (PDS) in patients with EOC. METHODS: PubMed, Embase, ClinicalTrials.gov, and Cochrane Library were queried to assess the therapeutic value of NACT versus PDS in EOC. Electronic databases were queried by using the keywords "ovarian cancer/neoplasms", "primary debulking surgery", and "neoadjuvant chemotherapy". RESULTS: The available trials were pooled, and hazard ratios (HRs), relative risk ratios (RRs) and associated 95% confidence intervals (95% CIs) were determined. Sixteen trials involving 57,450 participants with EOC (NACT, 9,475; PDS, 47,975) were evaluated. We found that NACT resulted in markedly decreased overall survival than PDS in patients with EOC (HR=1.30; 95% CI=1.13-1.49; heterogeneity: p<0.001, I²=82.7%). Furthermore, our results demonstrated that the NACT group displayed increased completeness of debulking removal (RR=1.69, 95% CI=1.32-2.17; heterogeneity: p<0.001, I²=81.9%), and reduced risk of postsurgical death (RR=0.18, 95% CI=0.06-0.51; heterogeneity: p=0.698, I²=0%) and major infection (RR=0.29, 95% CI=0.17-0.51; heterogeneity: p=0.777, I²=0%) compared with patients administered PDS. CONCLUSIONS: This meta-analysis indicated that NACT results in increased completeness of debulking removal, and reduced risk of postsurgical death and major infection compared with PDS, while PDS is associated with improved survival in comparison with NACT in EOC patients.

RESUMO

BACKGROUND & AIMS: Various enhanced recovery after surgery (ERAS) guidelines have been established for several kinds of adult surgeries. While the guidelines for pediatric surgeries remained to be explored. The aim of the study was to prospectively evaluate the safety and efficacy of an ERAS protocol for Hirschsprung's disease (HSCR) infants undergoing pull-through procedures. METHODS: An infant-specific ERAS protocol was developed and implemented at multiple centers from June 1, 2016 to December 31, 2017. The study included 145 consecutive patients who underwent pull-through surgery for HSCR in three Children's hospitals. Patients were primarily divided into three groups based on the clinical classification and surgical methods. Group I included patients with the short segment type who received transanal endorectal pull-through (TEPT) surgery. Group II comprised of patients with the classical type and long segment type who received laparoscopic-assisted pull-through (LAPT) surgery. Group III involved patients with the long segment type (who had received ileostomy or colostomy during the neonatal period) and total colonic aganglionosis who received open pull-through (OPPT) surgery. Patients in the three groups mentioned above were randomly and equally assigned into the ERAS group and traditional (TRAD) group with random number table row randomization. The primary outcome was the length of postoperative hospital stay (LOS). Secondary outcomes of interest included white blood cell (WBC) and C-reactive protein (CRP) on postoperative day 1 (POD 1), the blood glucose at the time of anesthesia and 24 h after surgery, time to first defecation, time to regular diet, plasma markers of nutrition status on POD 5, plasma natrium on POD 5, the mean intraoperative fluid volume, time to discontinuation of intravenous infusion, incidence of postoperative complications, re-admission within 30 days, hospitalization costs, parental satisfaction, and growth from admission to 6 months after surgery. RESULTS: 73 and 75 patients were assigned to the TRAD and ERAS groups, respectively. There were no significant differences in demographic data. The LOS decreased from 9.5 days in the TRAD group to 7.9 days (P < 0.001) in the ERAS group. WBC count on POD 1 showed no significant difference between the two groups. CRP on POD 1 in the ERAS group was significantly lower (P < 0.001). In the ERAS group, the blood glucose was higher at anesthesia compared to the TRAD group (P < 0.001). On the contrary, the blood glucose at 24 h after surgery was significantly lower in the ERAS group (P < 0.001). Intraoperative fluid volume was lower in the EARS group (P < 0.001). ERAS could also reduce the time to first defecation (P < 0.001), discontinuation of intravenous infusion (P < 0.001) and regular diet (P < 0.001). In the ERAS group, the concentrations of prealbumin and retinol conjugated protein on POD 5 were higher than those in the TRAD group (P < 0.001, P < 0.001, respectively). The plasma natrium had no difference in the two groups on POD 5 (P > 0.05). The rate of complications (P > 0.05) and 30-day re-admission (P > 0.05) were not significantly different between the two groups. Hospitalization costs were also reduced (P < 0.001). ERAS group has a higher parental satisfaction rate, although there was no statistical difference (96% vs 89%). There was no difference in growth between the ERAS and the TRAD groups from admission to 6 months after the surgery (weight for age z score: P > 0.05, weight for length z score: P > 0.05). We also found that the shortening of LOS by the application of ERAS protocol was more obvious in the OPPT group (-2.5 ± 1.0) than that in the TEPT (-1.9 ± 1.3) and LAPT (-1.3 ± 0.4) groups. CONCLUSIONS: Implementation of the ERAS protocol in infants undergoing HSCR pull-through operations is safe and efficient. The ERAS protocol is worthy of recommendation.

RESUMO

As a new class of non-coding RNA, circular RNAs (circRNAs) play crucial roles in the development and progression of various cancers. However, the detailed functions of circRNAs in cervical cancer have seldom been reported. In this study, circRNA sequence was applied to detect the differentially expressed circRNAs between cervical cancer tissues and adjacent normal tissues. The relationships between circCLK3 level with clinicopathological characteristics and prognosis were analyzed. In vitro CCK-8, cell count, cell colony, cell wound healing, transwell migration and invasion, and in vivo tumorigenesis and lung metastasis models were performed to evaluate the functions of circCLK3. The pull-down, RNA immunoprecipitation (RIP), luciferase reporter and rescue assays were employed to clarify the interaction between circCLK3 and miR-320a and the regulation of miR-320a on FoxM1. We found that the level of circCLK3 was remarkably higher in cervical cancer tissues than in adjacent normal tissues, and closely associated with tumor differentiation, FIGO stage and depth of stromal invasion. Down-regulated circCLK3 evidently inhibited cell growth and metastasis of cervical cancer in vitro and in vivo, while up-regulated circCLK3 significantly promoted cell growth and metastasis in vitro and in vivo. The pull-down, luciferase reporter and RIP assays demonstrated that circCLK3 directly bound to and sponge miR-320a. MiR-320a suppressed the expression of FoxM1 through directly binding to 3'UTR of FoxM1 mRNA. In addition, FoxM1 promoted cell proliferation, migration, and invasion of cervical cancer, while miR-320a suppressed cell proliferation, migration, and invasion through suppressing FoxM1, and circCLK3 enhanced cell proliferation, migration and invasion through sponging miR-320a and promoting FoxM1 expression. In summary, circCLK3 may serve as a novel diagnostic biomarker for disease progression and a promising molecular target for early diagnoses and treatments of cervical cancer.

RESUMO

BACKGROUND: Home enteral nutrition (HEN) is a safe and effective alternative to hospital-based enteral nutrition in North American and European countries; however, there is less data involving the use of HEN in infants in developing countries. We review our experience and data with HEN in patients who were followed in our center during the past 10 years. METHODS: This was a retrospective review of 58 patients who entered the HEN program in the Department of Neonatal Surgery at Children's Hospital of Nanjing Medical University between July 1, 2008 and June 30, 2018. Two kinds of nasal feeding programs were used in this study (24 h of continuously pumped milk [group A] and oral milk every 3 h in the daytime with continuously pumped milk for 12 h in the nighttime [group B]). The gender, age, primary disease, mode of HEN, and complications were reviewed. RESULTS: The average duration of HEN to full oral feeding was 3.5 months in group A and 3 months in group B. The incidence of diarrhea, vomiting, aspiration, and constipation between the two groups did not differ. Fifteen patients encountered problems related to the tube and 6 patients had problems with the micro-pump. The monthly cost of HEN was 3400 RMB in group A and 3200 RMB in group B. CONCLUSION: Under high quality care, HEN is safe and well-tolerated by infants after gastrointestinal surgery. Either as a continuous pump or as oral milk in the daytime and a continuous pump in the nighttime.

RESUMO

BACKGROUND: There are many advantages of a SMOF emulsion (SMOF-lipid), such as liver-protective properties and anti-inflammatory effects. The objective of this study was to compare the clinical outcomes of SMOF-lipid with medium-chain triglycerides (MCT) /long-chain triglycerides (LCT) in infants after intestinal surgery. METHODS: This was a prospective, randomized study. Neonates receiving intravenous nutrient solution, including lipid emulsion after gastrointestinal surgery, were included in this study. The patients were randomly assigned to the SMOF-lipid or MCT/LCT groups. Infants who received intravenous lipid emulsion continuously for > 2 weeks were considered to have completed the study. Differences in weight gain, nutrition indices, alanine transaminase (ALT), aspartate transaminase (AST), and direct bilirubin (DB), and inflammation cytokine markers (interleukin [IL]-6 and tumor necrosis factor [TNF]-α) were measured. RESULTS: The final sample included 160 infants. One hundred fourteen infants received intravenous SMOF-lipid (74) or MCT/LCT (86) > 2 weeks and 46 infants received intravenous SMOF-lipid (22) or MCT/LCT (24) > 4 weeks. There were no significant differences in weight gain, nutrition indices, inflammation cytokine markers, and sepsis between the groups at the end of 2 and 4 weeks; however, in the SMOF group, the ALT, AST, and DB levels were significantly lower than the MCT/LCT group at the end of 4 weeks. CONCLUSION: The mixture and balanced emulsion of SMOF-lipid was well-tolerated in infants who have undergone gastrointestinal surgery, and liver-protective properties were demonstrated following long-term venous nutrition, especially > 4 weeks.
