Survival from alcoholic hepatitis has not improved over time

Purpose/Background We aimed to describe changes in survival in alcoholic hepatitis (AH) over time by examining published data. Methods A systematic literature search of Ovid Embase and PubMed was undertaken using the MESH terms ‘hepatitis, alcoholic’ to identify randomised controlled trials (RCT) and observational studies (OS) in alcoholic hepatitis. Data were extracted from included studies regarding 28-day, 90-day, 180-day mortality, as well as biochemical and clinical data. Results After review of the literature search results, 77 studies published between 1971 and 2016 were analysed, which included data from a total of 8,184 patients. Overall mortality from AH was 26% at 28 days, 29% at 90 days and 44% at 180 days after admission. No changes in mortality over time were observed in univariable analysis at 28 days or 90 days after admission (Pearson correlation r -0.216, p = 0.098, and r 0.121 p = 0.503 respectively). A small but statistically significant increase in mortality was seen in 180-day mortality (r 0.461 p = 0.036). However, after meta-regression to adjust for other factors associated with mortality at each time point, no changes in mortality were seen. Sub-group analysis did not reveal any changes in mortality over time in different study types, or when only biopsy-proven or severe disease were considered. Conclusion There has been no improvement in mortality from AH. This is not explained by changes in severity of disease. This emphasises the urgent need for effective treatments for this alcoholic hepatitis.
Investigating the performance of geosynthetic-reinforced asphaltic pavement under various axle loads using finite-element method

One of the major factors influencing the performance of highway pavements is traffic loading, which is continuously increasing in number, magnitude and contact pressure. Geosynthetic reinforcement of asphalt pavements is a method for improving the bearing capacity of pavements against heavy traffic loads. This study aims to investigate the effectiveness of geosynthetic on the reduction of critical strains of flexible pavements under various axle load levels. Three types of geogrid have been placed in different positions in a typical asphalt pavement structure, and the critical strains, including the compressive vertical strain on top of subgrade, the maximum tensile strain at the bottom and the maximum shear strain of asphaltic layer have been evaluated under different axle loads of 5, 8.2 and 15 ton. The finite-element method has been utilised for modelling and analysis of pavement structure, in which, the asphaltic layer has been characterised as a viscoelastic material using Prony series. Results show that placing the geosynthetic beneath the asphaltic layer results in the reduction of the longitudinal tensile strain of asphaltic layer, while it is not effective on the vertical compressive strain on the subgrade. Furthermore, results show that, in spite of increasing the critical strains with increasing axle load, the effectiveness of geosynthetic reinforcement under different axle loads varied. At higher levels of axle load, the geosynthetic on the subgrade is more effective in reducing the compressive strain on the subgrade. However, the effectiveness of the geosynthetic beneath the asphaltic surface layer decreases with increasing axle load. In addition, the highest improvement in the effectiveness of geosynthetic for reducing the critical strains at higher axle load levels is achieved when it is placed at the position of the desired critical strain. It is also found that the effectiveness of geosynthetic in reducing the critical strains at higher axle loads increases with an increase in the modulus of geosynthetic.
The Voice of the Consumer: A Survey of Veterans and Other Users of Assistive Technology.

Introduction A total of 3.6 million Americans and over 250,000 veterans use wheelchairs. The need for advancements in mobility-assistive technologies is continually growing due to advances in medicine and rehabilitation that preserve and prolong the lives of people with disabilities, increases in the senior population, and increases in the number of veterans and civilians involved in conflict situations. The purpose of this study is to survey a large sample of veterans and other consumers with disabilities who use mobility-assistive technologies to identify priorities for future research and development. Materials and Methods This survey asked participants to provide opinions on the importance of developing various mobility-assistive technologies and to rank the importance of certain technologies. Participants were also asked to provide open-ended comments and suggestions. Results A total of 1,022 individuals, including 500 veterans, from 49 states within the USA and Puerto Rico completed the survey. The average age of respondents was 54.3 yr, and they represented both new and experienced users of mobility-assistive technologies. The largest diagnostic group was spinal cord injury (SCI) (N = 491, 48.0%). Several themes on critical areas of research emerged from the open-ended questions, which generated a total of 1,199 comments. Conclusion This survey revealed several themes for future research and development. Advanced wheelchair design, smart device applications, human-machine interfaces, and assistive robotics and intelligent systems emerged as priorities. Survey results also demonstrated the importance for researchers to understand the effects of policy and cost on translational research and to be involved in educating both consumers and providers.
Percutaneous Transhepatic Gallbladder Drainage Combined with Laparoscopic Cholecystectomy: A Meta-Analysis of Randomized Controlled Trials.

OBJECTIVE To investigate the clinical effect of the laparoscopic cholecystectomy (LC) after percutaneous transhepatic gallbladder drainage (PTGD) in elder acute cholecystitis. METHODS The Cochrane Library, PubMed, China National Knowledge Infrastructure (CNKI), VIP, and Wanfang Databases were searched for randomized controlled trials (RCTs) on LC after PTGD in elder acute cholecystitis published from 1970 to July 2017. Two researchers selected RCTs, extracted data, and evaluated methodological quality independently, and RevMan 5.3 software was used for the meta-analysis. The chi-square test was used for heterogeneity analysis of RCTs included, and the funnel plots were used to evaluate publication bias. RESULTS A total of 9 RCTs with 1000 patients were included in this analysis. Compared with the direct LC Group, the PTGD Group has significant better effect in operative duration (minutes) [standard mean difference (SMD) = -1.37, 95% confidence interval (95% CI): -2.52 to -0.22, P = . 02], the amount of intraoperative bleeding (mL) (SMD = -1.38, 95% CI: -2.11 to -0.65, P = .0002), conversion rate to laparotomy (%) [odds ratio (OR) = 0.16, 95% CI: 0.08 to 0.31, P < . 00001], postoperative complication morbidity (%) (OR = 0.29, 95% CI: 0.17 to 0.51, P < .0001), and postoperative hospital stay (days) (SMD = -1.26, 95% CI: -1.94 to -0.59, P = .0003). The funnel plots were slightly asymmetric, which suggested the presence of publication bias. CONCLUSION The PTGD before scheduled LC can effectively not only shorten operative duration, intraoperative bleeding less, and postoperative hospital stay but also decrease the rate to laparotomy and postoperative complication morbidity in elder acute cholecystitis, and it is recommended to be regarded as the preferred therapy of the elder patients.
Future Directions for Examination of Brain Networks in Neurodevelopmental Disorders

Neurodevelopmental disorders are associated with atypical development and maturation of brain networks. A recent focus on human connectomics research and the growing popularity of open science initiatives has created the ideal climate in which to make real progress toward understanding the neurobiology of disorders affecting youth. Here we outline future directions for neuroscience researchers examining brain networks in neurodevelopmental disorders, highlighting gaps in the current literature. We emphasize the importance of leveraging large neuroimaging and phenotypic data sets recently made available to the research community, and we suggest specific novel methodological approaches, including analysis of brain dynamics and structural connectivity, that have the potential to produce the greatest clinical insight. Transdiagnostic approaches will also become increasingly necessary as the Research Domain Criteria framework put forth by the National Institute of Mental Health permeates scientific discourse. During this exciting era of big data and increased computational sophistication of analytic tools, the possibilities for significant advancement in understanding neurodevelopmental disorders are limitless.
Production Practice During Language Learning Improves Comprehension

Language learners often spend more time comprehending than producing a new language. However, memory research suggests reasons to suspect that production practice might provide a stronger learning experience than comprehension practice. We tested the benefits of production during language learning and the degree to which this learning transfers to comprehension skill. We taught participants an artificial language containing multiple linguistic dependencies. Participants were randomly assigned to either a production- or a comprehension-learning condition, with conditions designed to balance attention demands and other known production–comprehension differences. After training, production-learning participants outperformed comprehension-learning participants on vocabulary comprehension and on comprehension tests of grammatical dependencies, even when we controlled for individual differences in vocabulary learning. This result shows that producing a language during learning can improve subsequent comprehension, which has implications for theories of memory and learning, language representations, and educational practices.
Kinetics of Double-Stranded DNA Viremia After Allogeneic Hematopoietic Cell Transplantation

Background Improved understanding of double-stranded DNA (dsDNA) virus kinetics after hematopoietic cell transplantation (HCT) would facilitate development of therapeutic strategies. Methods We tested weekly plasma samples from 404 patients through day 100 after allogeneic HCT for cytomegalovirus (CMV), human herpesvirus (HHV) 6A and 6B, BK polyomavirus (BKV), adenovirus (AdV), and Epstein-Barr virus (EBV) using quantitative polymerase chain reaction. Episodes lasting ≤1 week were defined as blips and >1 week as persistent. We described virus-specific kinetics, analyzed the association of virus area under the curve (AUC) with overall mortality, and identified risk factors for persistent episodes. Results We identified 428 episodes of CMV, 292 of BKV, 224 of HHV-6B, 46 of AdV, and 53 of EBV. CMV and BKV had the highest proportions of persistent episodes (68% and 80%, respectively). Detection and kinetics varied by virus. HHV-6B episodes reached maximum levels fastest and had the shortest intervals between detection and end-organ disease. End-organ disease occurred within 14 days of viremia in 68% of cases, generally during persistent episodes. For all viruses, higher viral load AUC increased risk for overall mortality through day 365, persistent episodes had higher viral load than blips, and higher first positive viral load significantly increased risk for persistent episodes. First viral load >2 log10 copies/mL (range, 2.04-3.06 per virus) had high specificity for persistent episodes. Conclusions Persistent high viral load dsDNA viremia episodes after allogeneic HCT predict mortality. Virus-specific kinetics can guide timing and thresholds for early intervention in studies of novel agents.
Direction of the Relationship Between Acceptance of Illness and Health-Related Quality of Life in Chronic Heart Failure Patients

Background: This study provides an in-depth insight into the relationships between illness acceptance and health-related quality of life (HRQoL) of chronic heart failure (CHF) patients. Although HRQoL is a well-established endpoint in CHF, little is known on illness acceptance in this group. Aims: The aim of this study is to critically reconsider the direction of a relationship between HRQoL and illness acceptance in CHF patients. Methods: The study included 204 patients (160 men and 44 women; mean age, 63 ± 11 years) with at least 6-month clinical evidence of CHF corresponding to New York heart Association (NYHA) classes I to IV. All the patients were examined with the Minnesota Living With Heart Failure Questionnaire (MLHFQ) and Acceptance of Illness Scale (AIS). Results: Univariate analysis showed that the level of illness acceptance correlated inversely with patient age, and the level of HRQoL decreased with the severity of CHF (NYHA class). A relationship between illness acceptance and HRQoL was analyzed by structural equation modeling. Model 1 was based on the assumption that HRQoL is modulated by illness acceptance, and model 2 tested the opposite relationship. Both models included patient age and NYHA class as extrinsic determinants of AIS and MLHFQ scores, respectively. Model 2 proved to be well fitted (&khgr;2 [df = 2] = 3.22, P = .20, root-mean-square error of approximation = 0.055). Scores on the AIS correlated inversely with age (bage->AIS = −0.15, SE = 0.05, P = .002) and HRQoL (bQoL->AIS = −0.15, SE = 0.02, P < .001), and an increase in NYHA class was reflected by an increase in HRQoL scores (bNYHA->QoL = 5.75, SE = 1.97, P = .004). Conclusion: Patients with CHF may not accept their disease due to deteriorated HRQoL. As a result, they may be uninvolved in the therapeutic process, which leads to exacerbation of CHF, further deterioration of HRQoL, and inability to accept the illness.
S-1 and irinotecan plus bevacizumab versus mFOLFOX6 or CapeOX plus bevacizumab as first-line treatment in patients with metastatic colorectal cancer (TRICOLORE): a randomized, open-label, phase III, noninferiority trial

Abstract Background Combination therapy with oral fluoropyrimidine and irinotecan has not yet been established as first-line treatment of metastatic colorectal cancer (mCRC). We carried out a randomized, open-label, phase III trial to determine whether S-1 and irinotecan plus bevacizumab is noninferior to mFOLFOX6 or CapeOX plus bevacizumab in terms of progression-free survival (PFS). Patients and methods Patients from 53 institutions who had previously untreated mCRC were randomly assigned (1 : 1) to receive either mFOLFOX6 or CapeOX plus bevacizumab (control group) or S-1 and irinotecan plus bevacizumab (experimental group; a 3-week regimen: intravenous infusions of irinotecan 150 mg/m2 and bevacizumab 7.5 mg/kg on day 1, oral S-1 80 mg/m2 twice daily for 2 weeks, followed by a 1-week rest; or a 4-week regimen: irinotecan 100 mg/m2 and bevacizumab 5 mg/kg on days 1 and 15, S-1 80 mg/m2 twice daily for 2 weeks, followed by a 2-week rest). The primary end point was PFS. The noninferiority margin was 1.25; noninferiority would be established if the upper limit of the 95% confidence interval (CI) for the hazard ratio (HR) of the control group versus the experimental group was less than this margin. Result Between June 2012 and September 2014, 487 patients underwent randomization. Two hundred and forty-three patients assigned to the control group and 241 assigned to the experimental group were included in the primary analysis. Median PFS was 10.8 months (95% CI 9.6–11.6) in the control group and 14.0 months (95% CI 12.4–15.5) in the experimental group (HR 0.84, 95% CI 0.70–1.02; P < 0.0001 for noninferiority, P = 0.0815 for superiority). One hundred and fifty-seven patients (64.9%) in the control group and 140 (58.6%) in the experimental group had adverse events of grade 3 or higher. Conclusion S-1 and irinotecan plus bevacizumab is noninferior to mFOLFOX6 or CapeOX plus bevacizumab with respect to PFS as first-line treatment of mCRC and could be a new standard treatment.

A survey of mobile phone use in the provision of palliative care services in the African region and priorities for future development

Introduction Palliative care (PC) services in the African region need to adapt to manage rising numbers of patients with cancer or other life-limiting conditions. Mobile phone use in healthcare delivery (mHealth) is at an early stage of development for PC, but may provide new approaches to supporting patients regionally, particularly those with non-communicable diseases. Methods We conducted an online survey of 51 PC providers across 21 countries in the African region to identify: (i) current mHealth use in PC service delivery; (ii) potential barriers to mHealth use; and (iii) provider priorities for research development. Results mHealth approaches were reported across 71.4% of services in which respondents were based. Barriers to mHealth research include patients not having access to phones, mobile network access, and limited access to expertise and hardware required for mHealth. Research priorities were identified which included exploring ways of incorporating mHealth into patient care and ensuring access and relevance of mHealth for patients and health professionals. Discussion mHealth approaches are present across PC services in the African region, but so too are barriers to their use. Further work is required to explore how existing mHealth activities might be further developed and aligned with priority areas for PC development. Crucially, user engagement that seeks to understand the preferences and priorities of patients with PC needs, their caregivers, and those involved in the provision of PC should remain central to these efforts.
Electrostatic Stabilization of a Native Protein Structure in the Gas Phase**

Recently, a general picture has been proposed of how long, and to what extent, native protein structure can be retained in the gas phase.1a In particular, molecular dynamics simulations suggest that salt bridges and ionic hydrogen bonds on the protein surface can transiently stabilize the global fold shortly after desolvation.1b However, the use of native mass spectrometry2 for studying protein solution structure is still controversial, mostly because site-specific experimental gas-phase data3 is scarce. Here we report electron capture dissociation (ECD)4 data on the gas-phase structures of the three-helix bundle protein KIX5 (Figure 1) that indicate substantial preservation of the native solution structure on a timescale of at least 4 s. We demonstrate that in the gas phase, the most stable regions are those stabilized by salt bridges and ionic hydrogen bonds.
Distinct Chemopreventive Effects of Aspirin in Diffuse and Intestinal-Type Gastric Cancer

Introduction: Although aspirin/NSAIDs may have potential preventive effects on several cancers, it remains unclear on gastric cancer. The purpose of this study is to compare the risk of developing gastric cancer and the histologic changes of intestinal metaplasia and neutrophil infiltration, between aspirin/NSAID users and nonusers. Methods: Using an electronic endoscopy database in two hospitals from 1996 to 2017, we analyzed the data from patients with chronic gastritis who received aspirin or NSAIDs prior to upper gastrointestinal endoscopy. One-to-one propensity score matching was performed to compare the proportion of gastric cancer, intestinal metaplasia, and neutrophil infiltration between these drug users and nonusers. Results: We analyzed 2,082 aspirin users and 2,082 nonusers as well as 898 NSAID users and 898 nonusers. Six diffuse-type and 19 intestinal-type gastric cancer, 1,243 intestinal metaplasia, and 1,503 neutrophil infiltration patients were identified. The proportion of diffuse-type gastric cancer (0.05%) was 80% lower in aspirin users compared with the nonusers (0.24%), and there was no case of diffuse-type cancer in patients who took aspirin for more than 2 years. In contrast, intestinal-type gastric cancer incidence was significantly higher in aspirin users (0.72%) compared with nonusers (0.14%). No significant differences in the incidence of gastric cancer were found between NSAID use and nonusers. NSAID use was significantly associated with decreased proportion of neutrophil infiltration compared with nonusers. Conclusion: Aspirin may have distinct effects between intestinal-type and diffuse-type gastric cancer development. Cancer Prev Res; 11(5); 279–86. ©2018 AACR.
Early signal of diverted use of tropicamide eye drops in France

AIMS Tropicamide is a mydriatic drug used as eye-drops for diagnostic or therapeutic purposes. From 2013, a diverted use by intravenous route has been suspected in Eastern Europe in opioids users. To date, no signal of misuse has been identified in France. The aims of this study were to investigate any early signals of a diverted use of tropicamide eye drops and to collect information regarding motives for the misuse and tropicamide-induced effects. METHODS Information was obtained at three levels: (1) at regional level (Midi-Pyrénées area), from reimbursement data and pharmacists' reports on suspicious requests; (2) at national level: from reimbursement data and prescriptions suggesting possible abuse from the OSIAP (Ordonnances Suspectes, Indicateur d'Abus Possible) survey; and (3) at international level: from VigiBase® reports and Web sources. Beta-blocker eye-drops were used as comparators. RESULTS In France, in 2014-2015, 17 (0.91%, 95% CI [0.53-1.46%]) falsified prescriptions involving tropicamide were identified in the OSIAP survey (compared with 0%, 95% CI [0-0.19%] for beta-blockers). Moreover, 37 other suspicious prescriptions were presented in 2015 (notified in 2016). In Midi-Pyrénées, seven patients aged 35-49 were reimbursed for 19-45 vials of 10 ml, in a year. Since September 2014, the regional Addictovigilance Centre has received 91 notifications of suspicious requests to obtain tropicamide. In VigiBase® , two cases were identified but none in France. An increased interest in tropicamide-related Internet searches was observed from Russia and Ukraine. CONCLUSIONS These results represent the first early warnings of a tropicamide diverted use in France. Tropicamide abusers would seek euphoria or hallucinations. The high doses involved in intravenous administration could lead to serious complications.
