Comparison of the effects of sugammadex and neostigmine on hospital stayin robot-assisted laparoscopic prostatectomy: a retrospective study

Abstract Background Sugammadex reduces postoperative complications. We sought to determine whether it could reduce the length of hospital stay, post-anesthetic recovery time, unplanned readmission, and charges for patients who underwent robot-assisted laparoscopic prostatectomy (RALP) when compared to neostigmine. Methods This was a retrospective observational study of patients who underwent RALP between July 2012 and July 2017, in whom rocuronium was used as a neuromuscular blocker. The primary outcome was the length of hospital stay after surgery in patients who underwent reversal with sugammadex when compared to those who underwent reversal with neostigmine. The secondary outcomes were post-anesthetic recovery time, hospital charges, and unplanned readmission within 30 days after RALP. Results In total, 1430 patients were enrolled. Using a generalized linear model in a propensity score-matched cohort, sugammadex use was associated with a 6% decrease in the length of hospital stay (mean: sugammadex 7.7 days vs. neostigmine 8.2 days; odds ratio [OR] 0.94, 95% confidence interval [CI] [0.89, 0.98], P = 0.008) and an 8% decrease in post-anesthetic recovery time (mean: sugammadex 36.7 min vs. neostigmine 40.2 min; OR 0.92, 95% CI [0.90, 0.94], P < 0.001) as compared to neostigmine use; however, it did not reduce the 30-day unplanned readmission rate (P = 0.288). The anesthesia charges were higher in the sugammadex group than in the neostigmine group (P < 0.001); however, there were no significant differences between the groups in terms of postoperative net charges (P = 0.061) and total charges (P = 0.100). Conclusions Compared to the reversal of rocuronium effects with neostigmine, reversal with sugammadex after RALP was associated with a shorter hospital stay and post-anesthetic recovery time, and was not associated with 30-day unplanned readmission rates and net charges

Failure of a Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy of H. pylori Eradication in H. pylori-Infected Patients with Functional Dyspepsia

BACKGROUND/AIMS: The role of Helicobacter pylori eradication in patients with functional dyspepsia (FD) is still uncertain. We originally planned a randomized clinical study to observe dyspeptic symptoms after H. pylori eradication therapy. However, we failed to complete the study; therefore, we analyzed the factors that affected the failure of the study. METHODS: Interviews and questionnaire surveys were conducted to analyze the factors that induced early termination from the study. RESULTS: Many patients were screened by gastroenterologists at 11 tertiary referral hospitals between July 2009 and August 2010; however, only 4 patients met the enrollment criteria. Most patients who visited our clinics had been experiencing FD symptoms for less than 6 months or were already taking medication. They also demanded to continue taking medications and using other drugs. Only 3 of the 4 patients signed informed consent. CONCLUSIONS: The application of the current Rome III criteria to FD is difficult to evaluate in Korean patients with dyspeptic symptoms because of the early medical evaluation. Most Korean patients who were diagnosed with FD by the Rome III criteria did not overcome their fear of being unable to use rescue medications during the study period.ope

Impact of diabetes mellitus on mortality in patients with acute heart failure: a prospective cohort study

Although more than one-third of the patients with acute heart failure (AHF) have diabetes mellitus (DM), it is unclear if DM has an adverse impact on clinical outcomes. This study compared the outcomes in patients hospitalized for AHF stratified by DM and left ventricular ejection fraction (LVEF). The Korean Acute Heart Failure registry prospectively enrolled and followed 5625 patients from March 2011 to February 2019. The primary endpoints were in-hospital and overall all-cause mortality. We evaluated the impact of DM on these endpoints according to HF subtypes and glycemic control. During a median follow-up of 3.5years, there were 235 (4.4%) in-hospital mortalities and 2500 (46.3%) overall mortalities. DM was significantly associated with increased overall mortality after adjusting for potential confounders (adjusted hazard ratio [HR] 1.11, 95% confidence interval [CI] 1.03–1.22). In the subgroup analysis, DM was associated with higher a risk of overall mortality in heart failure with reduced ejection fraction (HFrEF) only (adjusted HR 1.14, 95% CI 1.02–1.27). Inadequate glycemic control (HbA1c ≥ 7.0% within 1year after discharge) was significantly associated with a higher risk of overall mortality compared with adequate glycemic control (HbA1c < 7.0%) (44.0% vs. 36.8%, log-rank p = 0.016). DM is associated with a higher risk of overall mortality in AHF, especially HFrEF. Well-controlled diabetes (HbA1c < 7.0%) is associated with a lower risk of overall mortality compared to uncontrolled diabetes. Trial registration ClinicalTrial.gov, NCT01389843.

Impact of insulin therapy on the mortality of acute heart failure patients with diabetes mellitus

Background Patients with diabetes mellitus (DM) have a higher prevalence of heart failure (HF) than those without it. Approximately 40 % of HF patients have DM and they tend to have poorer outcomes than those without DM. This study evaluated the impact of insulin therapy on mortality among acute HF patients. Methods A total of 1740 patients from the Korean Acute Heart Failure registry with DM were included in this study. The risk of all-cause mortality according to insulin therapy was assessed using the Cox proportional hazard models with inverse probability of treatment weighting to balance the clinical characteristics (pretreatment covariates) between the groups. Results DM patients had been treated with either oral hypoglycemic agents (OHAs) alone (n = 620), insulin alone (n = 682), or insulin combined with OHAs (n = 438). The insulin alone group was associated with an increased mortality risk compared with the OHA alone group (HR = 1.41, 95 % CI 1.21–1.66]). Insulin therapy combined with OHAs also showed an increased mortality risk (HR = 1.29, 95 % CI 1.14–1.46) compared with the OHA alone group. Insulin therapy was consistently associated with increased mortality risk, regardless of the left ventricular ejection fraction (LVEF) or HF etiology. A significant increase in mortality was observed in patients with good glycemic control (HbA1c < 7.0 %) receiving insulin, whereas there was no significant association in patients with poor glycemic control (HbA1c ≥ 7.0%). Conclusions Insulin therapy was found to be associated with increased mortality compared to OHAs. The insulin therapy was harmful especially in patients with low HbA1c levels which may suggest the necessity of specific management strategies and blood sugar targets when using insulin in patients with HF.This study was supported by the Research of Korea Centers for Disease Control and Prevention (2010-E63003-00, 2011-E63002-00, 2012-E63005-00, 2013E63003-00, 2013-E63003-01, 2013-E63003-02, and 2016-ER6303-00

Constitutive activation of glycogen synthase kinase-3β correlates with better prognosis and cyclin-dependent kinase inhibitors in human gastric cancer

Background: Aberrant regulation of glycogen synthase kinase-3 beta (GSK-3 beta) has been implicated in several human cancers; however, it has not been reported in the gastric cancer tissues to date. The present study was performed to determine the expression status of active form of GSK-3 beta phosphorylated at Tyr(216) (pGSK-3 beta) and its relationship with other tumor-associated proteins in human gastric cancers. Methods: Immunohistochemistry was performed on tissue array slides containing 281 human gastric carcinoma specimens. In addition, gastric cancer cells were cultured and treated with a GSK-3 beta inhibitor lithium chloride (LiCl) for immunoblot analysis. Results: We found that pGSK-3 beta was expressed in 129 (46%) of 281 cases examined, and was higher in the early-stages of pathologic tumor-node-metastasis (P < 0.001). The expression of pGSK-3 beta inversely correlated with lymphatic invasion (P < 0.001) and lymph node metastasis (P < 0.001) and correlated with a longer patient survival (P < 0.001). In addition, pGSK-3 beta expression positively correlated with that of p16, p21, p27, p53, APC, PTEN, MGMT, SMAD4, or KAl1 (P < 0.05), but not with that of cyclin D1. This was confirmed by immunoblot analysis using SNU-668 gastric cancer cells treated with LiCl. Conclusions: GSK-3 beta activation was frequently observed in early-stage gastric carcinoma and was significantly correlated with better prognosis. Thus, these findings suggest that GSK-3 beta activation is a useful prognostic marker for the early-stage gastric cancer.Hirakawa H, 2009, ONCOL REP, V22, P481, DOI 10.3892/or_00000460Dar AA, 2009, ONCOGENE, V28, P866, DOI 10.1038/onc.2008.434Holmes T, 2008, STEM CELLS, V26, P1288, DOI 10.1634/stemcells.2007-0600Wang Q, 2008, CELL DEATH DIFFER, V15, P908, DOI 10.1038/cdd.2008.2Takahashi-Yanaga F, 2008, CELL SIGNAL, V20, P581, DOI 10.1016/j.cellsig.2007.10.018Pan MH, 2007, J AGR FOOD CHEM, V55, P7777, DOI 10.1021/jf071520hShakoori A, 2007, CANCER SCI, V98, P1388, DOI 10.1111/j.1349-7006.2007.00545.xZheng HC, 2007, ANTICANCER RES, V27, P3561Saegusa M, 2007, J PATHOL, V213, P35, DOI 10.1002/path.2198Ma C, 2007, CANCER RES, V67, P7756, DOI 10.1158/0008-5472.CAN-06-4665Forde JE, 2007, CELL MOL LIFE SCI, V64, P1930, DOI 10.1007/s00018-007-7045-7Li YW, 2007, J BIOL CHEM, V282, P21542, DOI 10.1074/jbc.M701978200Ding QQ, 2007, CANCER RES, V67, P4564, DOI 10.1158/0008-5472.CAN-06-1788Kunnimalaiyaan M, 2007, MOL CANCER THER, V6, P1151, DOI 10.1158/1535-7163.MCT-06-0665Soto-Cerrato V, 2007, MOL CANCER THER, V6, P362, DOI 10.1158/1535-7163.MCT-06-0266Cao Q, 2006, CELL RES, V16, P671, DOI 10.1038/sj.cr.7310078Yang CH, 2006, PRECIS AGRIC, V7, P33, DOI 10.1007/s11119-005-6788-0Crew KD, 2006, WORLD J GASTROENTERO, V12, P354Mai W, 2007, ONCOLOGY-BASEL, V71, P297, DOI 10.1159/000106429Tan J, 2005, CANCER RES, V65, P9012, DOI 10.1158/0008-5472.CAN-05-1226Shakoori A, 2005, BIOCHEM BIOPH RES CO, V334, P1365, DOI 10.1016/j.bbrc.2005.07.041Farago M, 2005, CANCER RES, V65, P5792Ghosh JC, 2005, CLIN CANCER RES, V11, P4580Liao XB, 2003, MOL CANCER THER, V2, P1215Lee HS, 2003, J PATHOL, V200, P39, DOI 10.1002/path.1288Doble BW, 2003, J CELL SCI, V116, P1175, DOI 10.1242/jcs.00384Gotoh J, 2003, CARCINOGENESIS, V24, P435Goto H, 2002, ORAL ONCOL, V38, P549Lee HS, 2001, INT J CANCER, V91, P619D`Amico M, 2000, J BIOL CHEM, V275, P32649, DOI 10.1074/jbc.M000643200Endoh Y, 2000, J PATHOL, V191, P257Wu LY, 1998, J NATL MED ASSOC, V90, P410WOODGETT JR, 1984, BIOCHIM BIOPHYS ACTA, V788, P339

Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

Combined searches for the production of supersymmetric top quark partners in proton-proton collisions at root s=13 TeV

A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb(-1) collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on themodel, the combined result excludes a top squarkmass up to 1325 GeV for amassless neutralino, and a neutralinomass up to 700 GeV for a top squarkmass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
