Three-year colonoscopy surveillance after polypectomy in Korea: a Korean Association for the Study of Intestinal Diseases (KASID) multicenter prospective study

Background/Aims Colonoscopic surveillance is currently recommended after polypectomy owing to the risk of newly developed colonic neoplasia. However, few studies have investigated colonoscopy surveillance in Asia. This multicenter and prospective study was undertaken to assess the incidence of advanced adenoma based on baseline adenoma findings at 3 years after colonoscopic polypectomy. Methods A total of 1,323 patients undergoing colonoscopic polypectomy were prospectively assigned to 3-year colonoscopy surveillance at 11 tertiary endoscopic centers. Relative risks for advanced adenoma after 3 years were calculated according to baseline adenoma characteristics. Results Among 1,323 patients enrolled, 387 patients (29.3%) were followed up, and the mean follow-up interval was 31.0±9.8 months. The percentage of patients with advanced adenoma on baseline colonoscopy was higher in the surveillance group compared to the non-surveillance group (34.4% vs. 25.7%). Advanced adenoma recurrence was observed in 17 patients (4.4%) at follow-up. The risk of advanced adenoma recurrence was 2 times greater in patients with baseline advanced adenoma than in those with baseline non-advanced adenoma, though the difference was not statistically significant (6.8% [9/133] vs. 3.1% [8/254], P=0.09). Advanced adenoma recurrence was observed only in males and in subjects aged ≥50 years. In contrast, adenoma recurrence was observed in 187 patients (48.3%) at follow-up. Male sex, older age (≥50 years), and multiple adenomas (≥3) at baseline were independent risk factors for adenoma recurrence. Conclusions A colonoscopy surveillance interval of 3 years in patients with baseline advanced adenoma can be considered appropriate.
Serum level of interleukin-6 (IL-6) and N-terminal propeptide of procollagen type I (PINP) in patients with liver diseases

Abstract Introduction: The aim of this study was to evaluate the concentration of interleukin-6 and N-terminal propeptide of procollagen type I and their relationship in liver diseases of different etiologies. Material and methods: Serum samples were obtained from 30 healthy volunteers and patients suffering from alcoholic cirrhosis (AC) – 31, non-alcoholic cirrhosis (NAC) – 28 and toxic hepatitis (HT) – 23 patients. Cirrhotic patients were classified according to Child–Pugh score. IL-6 and PINP concentrations were determined according to the electrochemiluminescence immunoassay. Results: The mean serum IL-6 concentration was significantly higher in AC (mean ± SD:21.52 ± 15.01 pg/mL), NAC (20.07 ± 32.12 pg/mL) and HT (15.14 ± 17.18 pg/mL) when compared to the control group (C) (1.67 ± 0.42 pg/mL) (Mann–Whitney U test: p < .001 for all comparisons). The mean serum PINP concentration was significantly higher only in patients with AC (104.32 ± 54.50 ng/mL) in comparison with the control group (54.70 ± 19.83 ng/mL; p < .001). The mean values of IL-6 and PINP significantly differed between liver diseases (ANOVA rank Kruskal–Wallis test: p = .020 and p < .001, respectively). Accordingly, the serum levels of IL-6 and PINP were significantly higher in patients with AC than that in NAC (p < .001 and p = .022, respectively). IL-6 and PINP concentrations appeared to vary depending on the severity of liver damage (p < .001 for both). The concentrations of IL-6 and PINP were significantly higher in class C (31.88 ± 21.51 pg/mL; 132.73 ± 65.63 ng/mL, respectively) than that in class A (6.12 ± 9.00 pg/mL; 57.32 ± 28.85 ng/mL, respectively) (p < .001 for both). There were also significant differences in IL-6 concentrations between Child–Pugh class B (27.88 ± 24.45 pg/mL) and class A (6.12 ± 9.00 pg/mL; p < .001). Conclusions: We conclude that serum concentrations of IL-6 and PINP change in liver diseases, and those changes reflect the severity of liver disease.
Genomewide transcriptional reprogramming in the seagrass Cymodocea nodosa under experimental ocean acidification

Here, we report the first use of massive‐scale RNA‐sequencing to explore seagrass response to CO2‐driven ocean acidification (OA). Large‐scale gene expression changes in the seagrass Cymodocea nodosa occurred at CO2 levels projected by the end of the century. C. nodosa transcriptome was obtained using Illumina RNA‐Seq technology and de novo assembly, and differential gene expression was explored in plants exposed to short‐term high CO2/low pH conditions. At high pCO2, there was a significant increased expression of transcripts associated with photosynthesis, including light reaction functions and CO2 fixation, and also to respiratory pathways, specifically for enzymes involved in glycolysis, in the tricarboxylic acid cycle and in the energy metabolism of the mitochondrial electron transport. The upregulation of respiratory metabolism is probably supported by the increased availability of photosynthates and increased energy demand for biosynthesis and stress‐related processes under elevated CO2 and low pH. The upregulation of several chaperones resembling heat stress‐induced changes in gene expression highlighted the positive role these proteins play in tolerance to intracellular acid stress in seagrasses. OA further modifies C. nodosa secondary metabolism inducing the transcription of enzymes related to biosynthesis of carbon‐based secondary compounds, in particular the synthesis of polyphenols and isoprenoid compounds that have a variety of biological functions including plant defence. By demonstrating which physiological processes are most sensitive to OA, this research provides a major advance in the understanding of seagrass metabolism in the context of altered seawater chemistry from global climate change.
A hybrid adaptive low-mach-number/compressible method. Part I: Euler equations

Flows in which the primary features of interest do not rely on high-frequency acoustic e ﬀ ects, but in which long-wavelength acoustics play a nontrivial role, present a computational chal-lenge. Integrating the entire domain with low-Mach-number methods would remove all acoustic wave propagation, while integrating the entire domain with the fully compressible equations can in some cases be prohibitively expensive due to the CFL time step constraint. For example, simulation of thermoacoustic instabilities might require ﬁ ne resolution of the ﬂ uid / chemistry interaction but not require ﬁ ne resolution of acoustic e ﬀ ects, yet one does not want to neglect the long-wavelength wave propagation and its interaction with the larger domain. The present paper introduces a new multi-level hybrid algorithm to address these types of phenomena. In this new approach, the fully compressible Euler equations are solved on the entire domain, potentially with local re ﬁ nement, while their low-Mach-number counterparts are solved on subregions of the domain with higher spatial resolution. The ﬁ nest of the compressible levels communicates inhomogeneous divergence constraints to the coarsest of the low-Mach-number levels, allowing the low-Mach-number levels to retain the long-wavelength acoustics. The performance of the hybrid method is shown for a series of test cases, including results from a simulation of the aeroacoustic propagation generated from a Kelvin-Helmholtz instability in low-Mach-number mixing layers. It is demonstrated that compared to a purely compressible approach, the hybrid method allows time-steps two orders of magnitude larger at the ﬁ nest level, leading to an overall reduction of the computational time by a factor of 8.
Consensus Guidelines for Therapeutic Drug Monitoring in Neuropsychopharmacology: Update 2017

Abstract Therapeutic drug monitoring (TDM) is the quantification and interpretation of drug concentrations in blood to optimize pharmacotherapy. It considers the interindividual variability of pharmacokinetics and thus enables personalized pharmacotherapy. In psychiatry and neurology, patient populations that may particularly benefit from TDM are children and adolescents, pregnant women, elderly patients, individuals with intellectual disabilities, patients with substance abuse disorders, forensic psychiatric patients or patients with known or suspected pharmacokinetic abnormalities. Non-response at therapeutic doses, uncertain drug adherence, suboptimal tolerability, or pharmacokinetic drug-drug interactions are typical indications for TDM. However, the potential benefits of TDM to optimize pharmacotherapy can only be obtained if the method is adequately integrated in the clinical treatment process. To supply treating physicians and laboratories with valid information on TDM, the TDM task force of the Arbeitsgemeinschaft für Neuropsychopharmakologie und Pharmakopsychiatrie (AGNP) issued their first guidelines for TDM in psychiatry in 2004. After an update in 2011, it was time for the next update. Following the new guidelines holds the potential to improve neuropsychopharmacotherapy, accelerate the recovery of many patients, and reduce health care costs.
Seattle’s minimum wage ordinance did not affect supermarket food prices by food processing category

Abstract Objective To examine the impacts of Seattle’s minimum wage ordinance on food prices by food processing category. Design Supermarket food prices were collected for 106 items using a University of Washington Center for Public Health Nutrition market basket at affected and unaffected supermarket chain stores at three times: March 2015 (1-month pre-policy enactment), May 2015 (1-month post-policy enactment) and May 2016 (1-year post-policy enactment). Food items were categorized into four food processing groups, from minimally to ultra-processed. Data were analysed across time using a multilevel, linear difference-in-differences model at the store and price level stratified by level of food processing. Setting Six large supermarket chain stores located in Seattle (‘intervention’) affected by the policy and six same-chain but unaffected stores in King County (‘control’), Washington, USA. Subjects One hundred and six food and beverage items. Results The largest change in average price by food item was +$US 0·53 for ‘processed foods’ in King County between 1-month post-policy and 1-year post-policy enactment (P < 0·01). The smallest change was $US 0·00 for ‘unprocessed or minimally processed foods’ in Seattle between 1-month post-policy and 1-year post-policy enactment (P = 0·94). No significant changes in averaged chain prices were observed across food processing level strata in Seattle v. King County stores at 1-month or 1-year post-policy enactment. Conclusions Supermarket food prices do not appear to be differentially impacted by Seattle’s minimum wage ordinance by level of the food’s processing. These results suggest that the early implementation of a city-level minimum wage policy does not alter supermarket food prices by level of food processing.
Decisive economies and opportunity cost of modular product structure alternatives: An empirical case study

Versatile, global markets as well as the increasing demand for more individualized products has increased the pressure on companies to offer a broad variety of products. Developing modular product families is an established approach to provide a suitable variety under economic conditions. However, balancing the demands for more external variety and less internal variety is a complex task for product development, affecting multiple domains in companies. In this paper, we conduct an empirical case study and investigate the correlating effects of external and internal variety on respective performance indicators (PI). Within two companies, we identify recurring chain reactions across ten decision scenarios and derive a subset of PIs affected by modular product structure alternatives (MPSA). In addition, the results highlight the major trade-offs between different target dimensions that occur while choosing dissimilar product structure alternatives.
Voltage instability investigation of Nigeria 330kV power network using continuation method

The present Nigeria Power system is facing voltage instability challenges as a result of increasing population and system loads, with inadequate capacity generation and poor power evacuation capability of transmission facilities. In this paper, modeling and simulations of voltage instability problems such as generators or lines loss, large disturbances or 3-phase faults and load changes in MATLAB/SIMULINK-based library Power System Analysis Toolbox (PSAT) environment are performed using the continuation power method. The computational procedures involved in these computer simulations are predictor, corrector and step size selection. The investigation results revealed that the present Nigeria 330kV power network cannot provide the sufficient power needed to illuminate the entire Nigeria with current increasing load demand and population growth, hence the critical bus voltages are not within the acceptable range of +5% tolerance of rated voltage value of 0.95PU (313.5KV) to 1.05PU (346.5KV). The real and reactive power losses for this power network are recorded as 3.1567pu (315.67MW), 3.3784pu (337.84MVar) and 1.2471pu (124.71MW), 0.03796pu (37.96MVar). The computed values of maximum loadability for continuation power-flow algorithm used to analyzed all the network buses of 28-bus Nigeria power system range from 4.046pu (404.60MW) to 4.8296pu (482.96MW) occurring after the load increases at buses 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 2.6006pu (260.06MW) to 4.8486pu (484.86MW) after 3-phase faults at 17–20 and 9–21 lines respectively.
The Effects of Discrimination Are Associated With Cigarette Smoking Among Black Males

ABSTRACT Previous research has demonstrated that experiencing interpersonal discrimination is associated with cigarette smoking. Few studies have examined the relationship between the effects of physical and emotional discrimination and cigarette usage, and none have examined this relationship among Black men. The aim of this study was to examine the association between the effects of physical and emotional discrimination and cigarette smoking. Methods: Data from the Indiana Black Men's Health Study, a community-based sample of adult Black men, was used to conduct multivariate logistic regression to examine the relationship between the physical and emotional effects of discrimination and smoking, net of healthcare and workplace discrimination, age, education, household income, and being married. Results: After adjusting for having an emotional response to discrimination, health care and workplace discrimination, age, education, household income, and being married, males who had a physical response to discrimination (e.g., upset stomach or headache) had higher odds of cigarette use (odds ratio (OR): 1.95, 95% confidence interval (CI): 1.15–3.30) than men who did not have a physical response to discrimination. Conclusion: Findings from the study suggest that Black males may use cigarette smoking as a means to mitigate the stress associated with experiences of discrimination. Future research is needed further to explore if and how Black males use cigarette smoking to cope with unfair treatment.
HHV-6 Infection in HIV-Infected Asymptomatic and AIDS Patients

In order to investigate the levels of HHV-6 infection and elevated antibodies to HHV-6 in HIV-1-infected asymptomatic and symptomatic patients, peripheral blood mononuclear cells were (PBMC) cultured. As patients progressed from asymptomatic HIV infection to AIDS, there was a concurrent increase in replicating HHV-6. Plasma obtained from several of these patients showed the presence of IgM antibody and a significantly elevated level of HHV-6 IgG antibody. Serial samples of plasma from 10 AIDS patients collected over a period of 4 years were assayed for the detection of HHV-6 core protein (gp116/64/54) by antigen capture ELISA. The results demonstrated that either a persistent infection or reactivation can occur based on the degree of fluctuation in HHV-6 antigen detected. ELISA to HHV-6 purified viral proteins, i.e., early (p41/38) and late (gp110), demonstrated that IgG antibody to gp110 did not differentiate between HIV-1-infected and healthy donors. IgG and IgM antibody to p41/38, however, showed a significantly higher prevalence in HIV-1-infected individuals (56.7–85.3%) than in normal healthy donors (19.0%), suggesting virus activation. PBMC culture from the AIDS patients expressing significant peaks of HHV-6 core antigen (gp116/64/54) in their plasma showed that in most cases, HHV-6 early and late antigens were detectable; however, those patients with consistently low antigen peaks had no detectable antigens in their PBMC. Only 55% of PBMC cultures established from IgM antibody-positive HIV-1-infected asymptomatic and AIDS patients expressed HHV-6 antigens in the short-term cultures, but HHV-6 antigens could not be demonstrated in PBMC culture from 4 IgM-antibody-positive healthy donors. HHV-6 isolates obtained from the HIV-1-positive patients were predominantly HHV-6 variant A, compared to healthy donors. Based on the data presented here, it is evident that the levels of HHV-6 infection increased in HIV-1-infected asymptomatic individuals as they progressed to AIDS. Our immunovirological data on HHV-6-infected individuals with HIV infection support a role for HHV-6 in the pathogenesis of AIDS. We believe that simultaneous active infection with HIV-1 and HHV-6 may contribute to enhanced immune suppression perhaps leading to disease manifestations.
Infectious virus in exhaled breath of symptomatic seasonal influenza cases from a college community

Significance Lack of human data on influenza virus aerosol shedding fuels debate over the importance of airborne transmission. We provide overwhelming evidence that humans generate infectious aerosols and quantitative data to improve mathematical models of transmission and public health interventions. We show that sneezing is rare and not important for—and that coughing is not required for—influenza virus aerosolization. Our findings, that upper and lower airway infection are independent and that fine-particle exhaled aerosols reflect infection in the lung, opened a pathway for a deeper understanding of the human biology of influenza infection and transmission. Our observation of an association between repeated vaccination and increased viral aerosol generation demonstrated the power of our method, but needs confirmation. Little is known about the amount and infectiousness of influenza virus shed into exhaled breath. This contributes to uncertainty about the importance of airborne influenza transmission. We screened 355 symptomatic volunteers with acute respiratory illness and report 142 cases with confirmed influenza infection who provided 218 paired nasopharyngeal (NP) and 30-minute breath samples (coarse >5-µm and fine ≤5-µm fractions) on days 1–3 after symptom onset. We assessed viral RNA copy number for all samples and cultured NP swabs and fine aerosols. We recovered infectious virus from 52 (39%) of the fine aerosols and 150 (89%) of the NP swabs with valid cultures. The geometric mean RNA copy numbers were 3.8 × 104/30-minutes fine-, 1.2 × 104/30-minutes coarse-aerosol sample, and 8.2 × 108 per NP swab. Fine- and coarse-aerosol viral RNA were positively associated with body mass index and number of coughs and negatively associated with increasing days since symptom onset in adjusted models. Fine-aerosol viral RNA was also positively associated with having influenza vaccination for both the current and prior season. NP swab viral RNA was positively associated with upper respiratory symptoms and negatively associated with age but was not significantly associated with fine- or coarse-aerosol viral RNA or their predictors. Sneezing was rare, and sneezing and coughing were not necessary for infectious aerosol generation. Our observations suggest that influenza infection in the upper and lower airways are compartmentalized and independent.
Abnormal Expression of Gastric Mucin in Human and Rat Aberrant Crypt Foci during Colon Carcinogenesis

Colorectal cancer is a major cause of death in Europe and the USA, and much effort is therefore devoted to improve its early detection. In this article, we report the abnormal expression of gastric mucin in aberrant crypt foci (ACF) that appear in the colon mucosae removed from colorectal cancer patients and rats treated with methyl-N′-nitro-N-nitroso-guanidine (MNNG). We performed the immunoperoxidase test using monoclonal antibodies raised against gastric M1 mucin encoded by the MUC5AC gene and against rat gastric mucins (MAb 660), respectively. In both human and rat colon, these anti-gastric mucin MAbs stained specifically goblet cells within ACF. In humans, the M1/MUC5AC mucin was expressed in the upper part of the glands in hyperplastic ACF and in the typical ACF. In addition, the anti-gastric mucin MAbs stained some rare, scattered, histologically normal glands in the human and rat colon mucosae. These glands may be regarded as precursors of ACF. The abnormal expression of the MUC5AC gene constitutes a novel change in addition to genetic modifications already observed in ACF, and supports our previous findings demonstrating the potential of this gastric mucin as an early marker of human and rat colon carcinogenesis.
A deep look into the spray coating process in real-time—the crucial role of x-rays

Tailoring functional thin films and coating by rapid solvent-based processes is the basis for the fabrication of large scale high-end applications in nanotechnology. Due to solvent loss of the solution or dispersion inherent in the installation of functional thin films and multilayers the spraying and drying processes are strongly governed by non-equilibrium kinetics, often passing through transient states, until the final structure is installed. Therefore, the challenge is to observe the structural build-up during these coating processes in a spatially and time-resolved manner on multiple time and length scales, from the nanostructure to macroscopic length scales. During installation, the interaction of solid–fluid interfaces and between the different layers, the flow and evaporation themselves determine the structure of the coating. Advanced x-ray scattering methods open a powerful pathway for observing the involved processes in situ, from the spray to the coating, and allow for gaining deep insight in the nanostructuring processes. This review first provides an overview over these rapidly evolving methods, with main focus on functional coatings, organic photovoltaics and organic electronics. Secondly the role and decisive advantage of x-rays is outlined. Thirdly, focusing on spray deposition as a rapidly emerging method, recent advances in investigations of spray deposition of functional materials and devices via advanced x-ray scattering methods are presented.
