Water Shutoff with Polymer in the Alvheim Field
Authors: Langaas Kåre , Stavland Arne
Published: November 2019

The Alvheim Field, offshore Norway, has subsea wells with long horizontal branches completed with sand screens. After 10 years of production, water production starts to constrain the oil production. Mechanical water shutoff is not possible in these wells; hence, other methods are of interest. In a well workover in 2013, two high-viscosity polymer pills were bullheaded and squeezed into the reservoir. The well productivity was reduced by approximately 50% and the water cut dropped, suggesting potentially higher oil recovery. A research study was started with the objectives of understanding the changed well performance and whether polymer bullheading can be a future method to reduce water production and enhance oil production.

An experimental laboratory program started with filtration tests of polymer solutions on the basis of the polymer used in the well operation. Coreflood experiments were performed by injecting polymer into two parallel-mounted cores and then back producing these individually with either water or oil. Several combinations of parallel cores were tested with polymer injection: high vs. low permeability, high oil saturation vs. low oil saturation, outcrop sandstone vs. Alvheim core, and two different polymer formulations.

The polymer formulation as used in the well operation demonstrated the plugging of standard filters with filter size larger than the reservoir pore sizes, but it did not plug the cores. The polymer formulation as used in the well gave a better disproportionate permeability reduction (DPR) than the alternative polymer variant with similar viscosity. A theoretical model for the shear rate in the porous media matched the experimentally measured data excellently. The core results show a stable permeability-reduction factor of 100 to 450 for water, while a factor of only 2 to 10 and decreasing with time for oil. The achieved DPR ratio of 45 to 80 is better than the trend from earlier published results.

The DPR as measured in the laboratory was next integrated into the reservoir model as part of the history match of the treated well. The Alvheim field has several reservoir zones separated with thin shales, and this reservoir zonation seems key for this enhanced-oil-recovery (EOR) method to work.

The laboratory work, the reservoir studies, and the field experience all point to a possible robust and simple EOR method for Alvheim and similar oil fields. Future work includes more research and maturing a new polymer pilot on Alvheim.

Published: November 2019

Background The association between cholesterol efflux capacity (CEC) with the occurrence and prognosis of coronary artery disease (CAD) remains unrevealed. In our study, a systematic review was performed to quantitively analyze the association between CEC and the risk of CAD and follow-up endpoint events of the patients with CAD.Methods A systematic search of electronic databases (PubMed, EMBASE, OVID, Web of Science and Cochrane Library) for studies published until September 2019 was performed. Cohort, case-control studies, and randomized controlled trials that examined the effect of CEC on risk and prognosis of CAD were included.Results Eighteen studies involving a total of 12615 subjects that met the inclusion criteria were included. Among them, 14 studies reported the CEC levels in control and CAD group and 8 of them analyzed the association of CEC with risk of CAD. Four studies reported the prognosis of CAD or acute coronary syndrome (ACS). From the pooled analyses, significantly decreased CEC level was shown in patients with stable CAD in comparison with the control. It was also true in subgroup analysis of the patients with ACS. The decreased CEC was significantly associated with increased risk of CAD (OR=0.65, 95% CI: 0.55-0.75, P<0.001). Decreased CEC level predicted higher all-cause (OR= 0.39, 95% CI: 0.20-0.77, P=0.007) and cardiovascular related mortality (OR= 0.34, 95% CI: 0.13-0.90, P=0.03) risk in patients with CAD. However, CEC levels failed to predict the occurrence of stroke and myocardial infraction in patients with CAD.Conclusions Decreased cholesterol efflux capacity is an independent risk factor for the occurrence of CAD patients, and its level predicts all-cause and cardiovascular related mortality risk in patients with CAD. Prospective studies should further investigate whether CEC control might improve outcomes in CAD patients.
Understanding variation in departmental adoption of Electronic Health Records: an embedded case study
Authors: Offenbeek Marjolein van , Boonstra Albert , Vos Janita F.J.
Published: November 2019

Background: Electronic Health Records (EHR) are integrated software applications used by healthcare providers to create, share, retrieve, and archive patients’ health status information. Especially for large healthcare organizations, implementing Electronic Health Records organization-wide is a complex endeavour. The EHR literature generally suggests that contextual factors play a major role in adoption. We demonstrate how the work context influences adoption at the departmental level in a situation where each department has its own medical specialty or patient stream, clinical authority, and accountability. Here, the achievement of full adoption by all departments is not self-evident. Drawing on EHR implementation in a Dutch hospital, this study explores how the clinical departments’ work context characteristics contribute to their pre-implementation intended adoption and their post-implementation EHR uptake. Methods: This embedded case study allowed us to examine the EHR adoption of eight diverse clinical departments in terms of their work and socio-political context. Data collection entailed semi-structured interviews, observing meetings, document analysis, and feedback sessions to check our interpretations. We examined the context and adoption intentions before implementation and the adoption level approximately half a year after the Go Live. The comparative case analysis iterated between holistic department-level descriptions and structured data displays based on inductive and deductive coding. Results: We identified three departmental types that varied both in adoption intention and post-implementation uptake: (1) departments oriented towards the organization with an enthusiastic or compliant adoption; (2) internal-oriented departments with a selective or conditional adoption; and (3) externally oriented departments with no or low adoption with workarounds. Conclusions: We conclude that work context characteristics contribute to individual departments’ adoption of an EHR. By acknowledging departmental types that will vary in adoption intention, and especially the underlying explanatory mechanisms, we recommend that implementers acknowledge these departmental types and differentiate their strategies towards clinical departments accordingly based on their observable work context characteristics. Based on these findings, we develop propositions that contribute to the development of a department-level EHR adoption theory.

Published: November 2019

Congenital malformations are described in about 3% of live births and 20% of stillbirths. In the industrialized countries, they represent one of the main causes of infant mortality, morbidity and handicap. In our country, as in all developing countries, the prevalence of congenital anomalies is not well known at the national level, besides, causes and risk factors are not always identified. The aim of our work is to conducta the first large descriptive exploratory analysis of congenital malformations cases diagnosed at the "Les Orangers" maternity and reproductive health hospital in Rabat. METHODS We have collected all the cases of congenital malformations diagnosed at the "Les Orangers" maternity and reproductive health hospital in Rabat for a period of five and a half years from January 1st, 2011 to June 30th, 2016. Data were collected on pre-established sheets and on a registry of malformations. Total and specific prevalences were calculated for each malformation then a principal component analysis was conducted followed by a Varimax rotation in order to identify the different associations of malformations in our series. RESULTS During the study period, a total of 43923 births were recorded. We have registred 245 cases of congenital malformations with a prevalence of 5.58 per thousand births of which 19.2% were fetal deaths in utero. The most representative anomalies were malformations of the osteoarticular system and muscles with a rate of 33%, followed by neurological abnormalities representing 18%, of whom 31% were hydrocephalus, 26.2% anencephaly, and 20.24% spina bifida. Malformations of the eye, ear, face and neck were described in 12% of the cases, while genetic abnormalities were observed in 8,5% of which 87.5% represented Trisomy 21. The antenatal diagnosis of congenital malformations was performed in 28.6% of cases. We observed a slight male predominance with a sex ratio of 1.19. CONCLUSIONS Congenital malformations are a real public health problem as they represent a major cause of stillbirth and neonatal mortality. Identifying and studying the causes and risk factors is a priorityin order to adapt a primary prevention strategy, especially folic acid supplementation to prevent neural tube closure defects.

Published: November 2019

Background: The need for early antibiotics in the intensive care unit (ICU) is often balanced against the goal of antibiotic stewardship. We sought to determine how short-course antibiotics in the ICU affect the antimicrobial resistance phenotype and genotype of colonizing gut bacteria. Results: Deep rectal swabs were performed on 48 adults at the time of ICU admission and 72 hours later, including patients who did and did not receive antibiotics. To determine resistance phenotype, rectal swabs were cultured for MRSA and VRE; in addition, Gram-negative isolates were cultured against relevant antibiotics. To determine resistance genotype, quantitative PCR was performed for 87 established resistance genes. Within-individual changes in antimicrobial resistance were calculated based on culture and qPCR results and correlated with exposure to relevant antibiotics (e.g., β-lactam exposure and changes in β-lactam resistance). Of 48 ICU patients, 41 (85%) received antibiotics. Overall, there was no increase in the antimicrobial resistance profile of colonizing gut bacteria during the 72 hour study period. There was also no increase in antimicrobial resistance after stratification by receipt of antibiotics (i.e., no increase in β-lactam, vancomycin, or macrolide resistance regardless of whether patients received those same antibiotics). This was true for both culture and PCR. Antimicrobial resistance pattern at ICU admission strongly predicted resistance pattern after 72 hours. Conclusions. Short-course ICU antibiotics made little difference in the antimicrobial resistance pattern of colonizing gut bacteria over 72 hours in the ICU. This provides improved understanding of the dynamics of antimicrobial resistance in the ICU and some reassurance that short-course antibiotics may not adversely impact the stewardship goal of reducing antimicrobial resistance.
Circular RNA SMARCA5 correlates with favorable clinical tumor features and prognosis, and increases chemotherapy sensitivity in intrahepatic cholangiocarcinoma
Authors: Qi Lu , Tao Fang
Published: November 2019

Background This present study aimed to investigate the correlation of circular RNA SMARCA5 (circ-SMARCA5) with clinicopathological features and overall survival (OS), and the effect of circ-SMARCA5 on cell proliferation and chemotherapy sensitivity to cisplatin/gemcitabine in intrahepatic cholangiocarcinoma (ICC).Methods Totally 92 primary ICC patients who underwent resection were recruited, and their tumor tissues, adjacent tissues were collected for circ-SMARCA5 detection. The effect of circ-SMARCA5 on cell proliferation and chemotherapy sensitivity was detected after circ-SMARCA5 overexpression plasmids transfection into TFK-1 and HuH-28 ICC cells.Results Circ-SMARCA5 expression was reduced in ICC tumor tissues compared to adjacent tissues. Tumor circ-SMARCA5 high expression was negatively associated with Eastern Cooperative Oncology Group performance score, T stage, N stage, TNM stage and abnormal CA199 status. Furthermore, OS was increased in patients with tumor circ-SMARCA5 high expression compared with those with low expression, and further multivariate Cox’s regression demonstrated that tumor circ-SMARCA5 high expression was an independent predictive factor for longer OS. In TFK-1 and HuH-28 ICC cells, circ-SMARCA5 upregulation decreased cell proliferation, reduced relative cell viability in cisplatin-treated as well as gemcitabine-treated cells, and also decreased inhibitory concentration by 50% value (IC50) of cisplatin and gemcitabine.Conclusions The correlation of circ-SMARCA5 with favorable clinical tumor features, survival profile, and its promoting effect on chemotherapy sensitivity imply its potential as a valuable biomarker in monitoring disease progression and prognosis of ICC.

Published: November 2019

Pregnancy and parenthood have been associated with physical and mental health. Previous literature concerning the impacts of parity on mental health was inconsistent and lack epidemiolocal evidence. China, with growing mental health problems and changing fertility patterns, faces unique challenges. This study aims to examine the relationship between parity and the prevalence of major depression and insomnia among men and women in the Chinese population. Methods Baseline data from a Chinese population-based study of 512,891 adults (59.01% women) from 10 areas, aged 30-79 were analyzed. Number of children were based on self-report by the participants. Major depression (MD) was assessed using the Composite International Diagnostic Inventory. Insomnia symptoms were accessed by questionnaire comparable to that used in Diagnostic and Statistical Manual of Mental Disorders. Logistic regression was used to assess the relationship between MD/Insomnia and number of children, after stratifications and adjustments. Results For women, each additional child was associated with a 9% decreased odds of MD (OR: 0.91, 95%CI: 0.88-0.96), with the associations significant for those who lived in urban areas (OR: 0.76, 95%CI: 0.70-0.83), or had a lower education (OR: 0.90, 95%CI: 0.85-0.94), or had lower household income (OR: 0.89, 95%CI: 0.85-0.94), or had ever used alcohol (OR: 0.89, 95%CI: 0.84-0.93). The association between per additional children and MD was not significant in men (OR: 1.02, 95%CI: 0.97-1.07) but a decreased odds of MD with per additional child was found in men who lived in urban areas (OR: 0.81, 95%CI: 0.71-0.96). For women, each additional child was associated with a 4% decreased odds of insomnia (OR: 0.96, 95%CI: 0.95-0.96). Each additional child was also associated with a 2% decreased odds of insomnia in men (OR: 0.98, 95%CI: 0.97-1.00). Conclusions MD and insomnia was associated with number of children, particularly in women and the association was mediated by socioeconomic and lifestyle factors. Future mental health public health programs should address parity and sex differences when designing interventions.

Pneumoconiosis has the potential to cause progressive and permanent physical disability. And continues to be one of major public health concern across the world. However, our literature searches identified a scarcity of data about global prevalence of pneumoconiosis. Accurate data on the incidence of pneumoconiosis is critical for health resource planning and health policy development. We therefore aimed to determine the pattern of pneumoconiosis incidence and temporal trends. Methods: Annual incident cases and age standardized incidence rates on pneumoconiosis etiology between 1990-2017 were collected from the Global Burden of Disease Study 2017. We calculate the average annual percentage changes of age standardized incidence rates by sex, region, and etiology to determine incidence trends of pneumoconiosis. Results: Globally, the number of pneumoconiosis cases increased 66.0% from 36,186 in 1990 to 60,055 in 2017. The overall age standardized incidence rate decreased by an average 0.6% (95% CI: 0.5%, 0.6%) per year in the same period. The age standardized incidence rate of silicosis, asbestosis, and other pneumoconiosis decreased between 1990 and 2017. The corresponding average annual percentage changes were -0.8%, -0.9%, and -0.5%, respectively. The age standardized incidence rate of asbestosis displayed an increasing trend. At the same time, we also found a significant negative association was found between average annual percentage changes and socio-demographic indexs when the socio-demographic index above 0.7. Conclusions: Pneumoconiosis remains a major occupational health illnesses in the world. Incidence patterns of pneumoconiosis caused by different etiologies were heterogeneous across regions and countries. We observed an unfavorable trend that asbestosis was predominant in countries with a high socio-demographic index, though we have attained great achievements in silicosis and coal workers’ pneumoconiosis prevention. The information in this study suggests that some countries should establish more targeted and specific strategies to forestall the increase in pneumoconiosis.

Published: November 2019

Background This study aimed to investigate the roles of CYP3A4 and CYP11A1 variants in ischemic stroke (IS) susceptibility among the Han Chinese population. Methods 477 patients with IS and 493 healthy controls were enrolled. Seven single-nucleotide polymorphisms (SNPs) of CYP3A4 and CYP11A1 were genotyped by Agena MassARRAY. Odds ratio (OR) and 95% confidence intervals (CI) were calculated by logistic regression adjusted for age and gender. Results We found that CYP3A4 rs3735451 (OR = 0.81, p = 0.039) and rs4646440 (OR = 0.72, p = 0.021) polymorphisms decreased the risk of IS. CYP3A4 rs4646440 (OR = 0.74, p = 0.038) and CYP11A1 rs12912592 (OR = 1.58, p = 0.034) polymorphisms were correlated with IS risk in males. CYP3A4 rs3735451 (OR = 0.63, p = 0.031) and rs4646440 (OR = 0.57, p = 0.012) possibly weaken the IS susceptibility at age > 61 years. Besides, CYP3A4 rs4646437 (OR = 0.59, p = 0.029), CYP11A1 rs12912592 (OR = 1.84, p = 0.017) and rs28681535 (OR = 0.66, p = 0.038) were associated with IS risk at age ≤ 61 years. CYP11A1 rs28681535 TT genotype was higher high-density lipoprotein cholesterol level than the GT and GG genotype (p = 0.027). Conclusions Our findings indicated that rs3735451, rs4646440, rs4646437 in CYP3A4 and rs28681535 in CYP11A1 might be protective factors for IS, while CYP11A1 rs12912592 polymorphism be a risk factor for IS in Chinese Han population.
Level of Knowledge Awareness and Use of Planning as Writing Strategy by EFL International Students in UUM English Intensive Course
Authors: Ado Mohammed Ahmed , Alsheyab Mohammad Othman Ahmad
Published: November 2019

Malaysian English Language Curriculum makes it compulsory for every newly intake student to master and pass the English Writing Tasks (EWT) as among the basic skills in the language learning processes. However, most of the English Foreign Language (EFL) international students face difficulties with the EWT during the English Intensive Course (EIC) leading to consistent mass failures. The possible reasons of these failures could be due to the neglect of the writing strategies. Hence, the central focus of this paper is to identify and determine the EFL international students’ level of awareness and the use of planning as writing strategy before writing English essays. To this end, convenient purposive sampling strategy was used where 50 EFL (postgraduate and undergraduate) international students drawn from Universiti Utara Malaysian EIC program were selected and administered Writing Strategy Questionnaires (WSQ). The participants hailed from various countries who used and learned English as a foreign language, namely; Jordan, Iraq, Saudi Arabia, Libya, Palestine among others. The data were analyzed using SPSS. The findings revealed proportionate disparity between the EFL students that use planning strategy before starting writing English essays (usually true = 28%) with those that do not (usually not true = 28%). In terms of Revising Requirement for writing process before one start writing an essay in English, the findings revealed validity (40%) of participants’ responses at 82% cumulative. This is followed by “somewhat true” responses at 24% and 42% cumulative. These imply the EFL international students’ reasonable use of planning and having knowledge awareness of writing strategy
Job stress and turnover intention revisited: evidence from Korean firms
Authors: Ahn Ji-Young , Chaoyu Wang
Published: November 2019

This study revisits the relationship between job stress and turnover intention for employees using a sample of employees in public companies of Korea. The authors investigate both the effect of job stress on turnover and the process by which job stress affects employee turnover. In particular, they prove that job satisfaction mediates the relationship between stress and turnover intention of the employees. Furthermore, the authors explore the job stress-turnover relationship by extending a review of the organizational justice perspective and posit whether an employee perceived organizational justice could mitigate the presumed adverse effects of job stress on turnover intention. They suggest empirical evidence that there is a significant positive relationship between job stress and turnover intention, and that job satisfaction partially mediates this relationship. However, the authors found no strong evidence of moderating roles of perceived organizational justice. Based on the job demands-resources (JDR) model, the relationship between job stress and turnover intention is evidenced. Besides, the study implies that the incidence of perceived organizational justice fails to mitigate the effect of these value-decreasing job stressors on employee turnover.
Methotrexate and Vasculoprotection: Mechanistic Insights and Potential Therapeutic Applications in Old Age

Published: November 2019

Increasing age is a strong, independent risk factor for atherosclerosis and cardiovascular disease. Key
abnormalities driving cardiovascular risk in old age include endothelial dysfunction, increased arterial stiffness,
blood pressure, and the pro-atherosclerotic effects of chronic, low-grade, inflammation. The identification of
novel therapies that comprehensively target these alterations might lead to a major breakthrough in cardiovascular
risk management in the older population. Systematic reviews and meta-analyses of observational studies have
shown that methotrexate, a first-line synthetic disease-modifying anti-rheumatic drug, significantly reduces
cardiovascular morbidity and mortality in patients with rheumatoid arthritis, a human model of systemic
inflammation, premature atherosclerosis, and vascular aging. We reviewed in vitro and in vivo studies
investigating the effects of methotrexate on endothelial function, arterial stiffness, and blood pressure, and the
potential mechanisms of action involved. The available evidence suggests that methotrexate might have beneficial
effects on vascular homeostasis and blood pressure control by targeting specific inflammatory pathways,
adenosine metabolism, and 5' adenosine monophosphate-activated protein kinase. Such effects might be
biologically and clinically relevant not only in patients with rheumatoid arthritis but also in older adults with high
cardiovascular risk. Therefore, methotrexate has the potential to be repurposed for cardiovascular risk
management in old age because of its putative pharmacological effects on inflammation, vascular homeostasis,
and blood pressure. However, further study and confirmation of these effects are essential in order to adequately
design intervention studies of methotrexate in the older population.

:

Flavonoids are a large group of naturally occurring compounds, which are of interest due to their great pharmacological effects and health-promoting impacts. These properties have led to their extensive application in a variety of pathological conditions, particularly cancer. Flavonoids are used in large quantities in a human's daily diet and a high amount of flavonoids are found in the intestine after oral usage. However, flavonoid concentrations in tissue/plasma are low because of their low bioavailability, the leading to the low efficacy of flavonoids in different clinical disorders. For this reason, nanotechnology application for delivering flavonoids to tumor sites has recently received significant attention. Silibinin is a key member of flavonoids and a bioactive component of silymarin, which is widely isolated from Silybum marianum. This plant-derived chemical has a number of valuable biological and therapeutic activities such as antioxidant, anti-inflammatory, neuroprotective, anti-tumor, hepatoprotective, cardioprotective and anti-diabetic. These beneficial effects have been demonstrated in in vivo and in vitro experiments. However, it seems that silibinin has a variety of limitations and poor bioavailability is the most important factor restricting its wide application. Hence, there have been attempts to improve the bioavailability of silibinin and it has been suggested that nano-soldiers are potential candidates for this aim. In the present review, we describe the different drug delivery systems for improving the bioavailability of silibinin.

Published: November 2019

Storytelling essentials are stories that direct attention, trigger emotions, and prompt understanding. Citizen science has recently promoted the narrative approach of storytelling as a means of engagement of people of all ages and backgrounds in scientific research processes. We seek understanding about the typology of storytelling in citizen science projects and explore to what extent the tool of storytelling can be conceptualized in the approach of citizen science. In a first step, we investigated the use and integration of storytelling in citizen science projects in the three European German-speaking countries. We conducted a low threshold content analysis of 209 projects listed on the German-speaking online platforms for citizen science projects “Bürger schaffen Wissen”, “Österreich forscht”, and “Schweiz forscht”. Two expert workshops with citizen science practitioners were held to validate and discuss the identified role of stories in the practice of citizen science. Our analysis revealed three major categories mirroring how stories are being integrated and applied in citizen science. The first category refers to projects, in which stories are the core research objective. The second category is characterized by the application of stories in different phases of the research project. The third category encompasses stories as agents being part of the communication and organization of the project. We illustrate the practical application of these categories by three representative case studies. By combining the functionality of the categories and abstracting the linkages between storytelling and citizen science, we derived a generalized model accounting for those linkages. In conclusion, we suggest that storytelling should be a prerequisite to enhance the competencies of the actors involved and to exchange knowledge at the interfaces of science and policy as well as science and society.

Published: November 2019

Peony is a less utilized herbaceous plant of ornamental and medicinal relevance. The petals are rich in bioactive phenolics and hence, the development of efficient extraction is required for maximum recovery and bioactivity. In this study, the optimal conditions for the ultrasound-assisted extraction of peony phenolics were first investigated by comparing to conventional extraction and testing the data fit by mathematical models (linear, two factor interactions, quadratic) followed by investigation of cellulase pre-treatment combined with ultrasonication. High amounts of flavonoids, phenolics and tannins were extracted in 30 min under ultrasound conditions of 150 W, 40 kHz, 50 % amplitude, in 70 % ethanol with 50/1 solvent/solid ratio. A further cellulase pre-treatment at 40 ?C for different incubation times combined with ultrasonication facilitated the extraction of anthocyanins (720.48 mg/100 g DW), phenolics (3985.50 mg/100 g DW), flavonoids (2369.28 mg/100 g DW) and tannins (8917.81 mg/100 g DW). Good antioxidant activities by FRAP (350.03 mg ascorbic acid/100 g DW) and DPPH (inhibition values >80 %) were registered showing great potential for developing high-value bioingredients. The FTIR analysis revealed the presence of characteristic functional groups. The hereby- -combined extraction methods could be extended to other peony species.
