During CPR, coronary and cerebral perfusion pressures and femoral artery pressure did not differ between groups; however, end-tidal COand mixed venous O
saturation were higher, and pulmonary artery pressure was lower (p < 0.05) for TVCPR than Control. During TVCPR, switching to 100 cpm increased coronary perfusion pressure (p < 0.05), and switching to 200 cpm increased cerebral perfusion pressure (p < 0.05).
Time-varying CPR significantly improved indicators of net forward blood flow and proportion of ROSC over time without negatively impacting perfusion pressures. Alternating CC rate alternates between perfusion pressures favoring the brain and those favoring the heart. Time-varying CPR represents a new avenue of research for optimizing CPR.

Inadequate bowel preparation before colonoscopy has a 20-30% rate and impedes on the quality of the procedure. The aim of this study was to develop a predictive score of inadequate bowel preparation, using a patient questionnaire on potential risk factors.
In this single center study, consecutive patients with colonoscopy indication were enrolled. The primary outcome was inadequate bowel preparation defined by Boston Bowel Preparation Scale (BBPS) score <7 or a score ≤1 in any of the 3 colonic segments.
A total of 561 patients were included. Inadequate bowel preparation was seen in 25.0% of cases. Seven risk factors were selected into the prediction model of inadequate bowel preparation diabetes or obesity, irregular physical activity, cirrhosis, use of antidepressants or neuroleptics, use of opiate medication, history of surgery and history of inadequate bowel preparation. The risk score, named PREPA-CO, had an AUROC of 0.621, adequately predicted bowel cleanliness in 68.3% of cases, with a specificity of 75.8% and a negative predictive value of 80.8%.
We developed a predictive score named "Prepa-Co", allowing the identification of patients at high risk of inadequate bowel preparation. In clinical practice, this score could help tailor the prescription of the preparation to the patient.

Hepatoblastoma (HB) is a rare embryonal liver tumor of children. click here Although intrinsic biological differences between tumors can affect prognosis, few groups have studied these differences. Given the recent increased attention to epigenetic mechanisms in the genesis and progression of these tumors, we aimed to classify HB samples according to the stages of liver development and DNA methylation machinery.
We evaluated the expression of 24 genes associated with DNA methylation and stages of hepatocyte differentiation and global DNA methylation. Using bioinformatics tools and expression data, we propose a stratification model for HB.
Tumors clustered into three groups that presented specific gene expression profiles of the panel of DNA methylation enzymes and hepatocyte differentiation markers. In addition to reinforcing these embryonal tumors' molecular heterogeneity, we propose that a panel of 13 genes can stratify HBs (TET1, TET2, TET3, DNMT1, DNMT3A, UHRF1, ALB, CYP3A4, TDO2, UGT1A1, AFP, HNF4A, and FOXA2). DNA methylation machinery participates in the characterization of HBs, directly reflected in diverse DNA methylation content. The data suggested that a subset of HBs were similar to differentiated livers, with upregulation of mature hepatocyte markers, decreased expression of DNA methylation enzymes, and higher global methylation levels; these findings might predict worse outcomes.
HBs are heterogeneous tumors. Despite using a small cohort of 21 HB samples, our findings reinforce that DNA methylation is a robust biomarker for this tumor type.

Liver cirrhosis profoundly affects the immune system, leading to an immunological imbalance known as cirrhosis-associated immune dysfunction.
This study aimed to investigate B-cell disturbances in patients with acute decompensation (AD) of cirrhosis and assess relationships with prognosis and mortality.
The study included 39 patients with AD of cirrhosis, 29 patients with stable cirrhosis (SC), and 30 healthy controls (CTR). Circulating B-cell subsets and cytokine plasma levels were determined by flow cytometry.
Cirrhotic groups showed higher percentages of naïve B cells, and lower percentages of CD27
memory B cells (MBCs) than CTR. Further analysis comparing SC and AD revealed that the latter had higher frequencies of double-negative (DN) B cells and plasmablasts. Patients with more advanced liver disease exhibited a B-cell maturation shift toward MBCs and plasmablasts. Acute-on-chronic liver failure (ACLF) was associated with higher DN frequency. The Kaplan-Meier one-year survival probability was 92.9% in patients with >1.3% of transitional B cells and 27.3% in patients with <1.3%.
B-cell subsets are markedly altered in cirrhotic patients, and cell profiles differ between stable and decompensated liver disease. Increased frequencies of DN B cells and reduced proportions of transitional B cells may be of great relevance in predicting ACLF and mortality, respectively.

The prevalence and prognosis association of microsatellite instability (MSI) in oesogastric junction and gastric adenocarcinoma (OGC) have been reported with conflicting results.
Patients with OGC from 2010 to 2015 were enrolled in this retrospective multicenter study. MSI was determined by genotyping. MLH1 promoter methylation and BRAFV600E mutation were screened in the MSI tumors.
Among 315 tumors analyzed, 39 (12.4%) were of the MSI phenotype. Compared to MSS tumors, MSI tumors were more frequent in patients >70 years (17% vs 9%, p=0.048) and in gastric antral primary (20% versus 5% in junction tumor and 12% in fundus tumor. Among 29 MSI tumors analyzed, 28 had a loss of MLH1 protein expression and 27 had MLH1 promotor hypermethylation. None had a BRAF V600E mutation. The 4-year cumulative incidence of recurrence for patients with resected tumor was significantly lower in dMMR tumors versus pMMR tumors (17% versus 47%, p=0.01). For the patients with unresectable tumor the median overall survival was 11 months in MSS group and 14 months in MSI group (p=0.
