Technology Focus: Field Development (September 2020)
Authors: Capello Maria A. 
Published: September 2020

Field developers have shifted the usual approach to planning and operations to a “dare to try” approach, experimenting, piloting, and directly implementing from the start a digital transformation of their activities. Under the mandate of decarbonization and safe operations embraced by many international, national, and service oil companies, there is no turning back on an accelerated journey of field-development projects that are moving toward automatic production optimization and predictive maintenance loops.
Real and tangible results are available, proving that shifting the focus on operations to a digital approach, using digital twins, machine learning, and artificial intelligence (AI) truly benefits operators in three main aspects: safety, monetization of investment, and low carbon. Operators who do not engage in this wave most probably will lose competitive advantage soon.
Swift innovation in field development was accelerated by the commanding need to reduce operating costs because of low oil prices during the last 2 years and by the imperative urgency of enabling remote and distance-conscious working during the current pandemic. The developments in engineering and digital technology are being integrated to launch solutions never envisioned before, such as wind farms offshore to provide more electricity where it is needed without affecting the environment and North Sea developments modeled on digital twins with little or no staffing. Collaboration among a variety of companies, big and small, is also a preferred approach, leading the way toward the sure digital future in oil and gas.
What I consider extremely relevant is the speed with which these improvements are taking place. The selection of articles in this section illustrates three main facets of this vertiginous speed: offshore developments modeled on digital twins that include decarbonization and digitalization implementations that take only months (literally), AI percolating the modeling strategies and consultancy services for large oil and gas operators, and the remarkable innovation of producing electricity with floating wind farms in offshore fields.
We live in an exciting transformation era, in which “dare to try” is needed, and we need to learn from any mistakes quickly to shape better field developments that take care of the environment, reduce costs, and increase safety. A failure to dare now will penalize operators who did not grip the imminent change.

Abstract
Background: An extended duration of breastfeeding of up to two years is encouraged by many health authorities, but information regarding the composition of milk after one year postpartum is limited. The goal of this study was to determine the associations of macronutrient contents, immunoglobulin A (IgA) levels, and the total antioxidant capacity (TAC) in human milk (HM) with the month of lactation from 1 to 24 months postpartum.Methods: Milk samples were collected from mothers with healthy full-term children who had been lactating from 1 to 24 months from January 2019 to April 2019. The HM was biochemically analyzed for protein and carbohydrate contents by colorimetric assays. The fat content was determined by capillary centrifugation, and the energy content was calculated from the results of centrifugation assays. IgA levels and the TAC were determined by ELISA and a Trolox equivalent antioxidant capacity (TEAC) assay, respectively. Pearson’s correlation coefficient and Spearman’s rank correlation coefficient were used to determine associations between milk composition and the month of lactation, and multiple regression analysis was used to assess the association between the covariates and milk composition. Differences were considered significant at p < 0.05.Results: One hundred eighty-four milk samples were analyzed. The month of lactation was positively associated with the fat concentration (B = 0.31, SE = 0.09, p = 0.001), energy content (B = 3.11, SE = 0.92, p = 0.001), and IgA (B = 4.17, SE = 1.08, p < 0.001) but negatively associated with the carbohydrate concentration (B = -0.22, SE = 0.01, p = 0.04). No association was observed between the month of lactation and the protein concentration and TAC after adjustment for maternal age, maternal BMI, birth order, and breastfeeding frequency.Conclusions: The month of lactation was found to be positively associated with the fat, energy, and IgA in HM for up to two years postpartum and slightly but significantly negatively associated with carbohydrate concentration. More prospective cohort studies are needed to obtain evidence-based knowledge regarding the changes in HM composition throughout the course of lactation.

Abstract
Background: Quality of life (QoL) is multi-dimensional concept of an individual’ general well-being status in relation to their value, environment, cultural and social context in which they live. This study aimed to quantitatively synthesise available evidence on the association between QoL and mortality in the general population. Methods: An electronic search was conducted using three bibliographic databases, MEDLINE, EMBASE and PsycINFO. Inclusion criteria were studies that assessed QoL using standardized tools and examined mortality risk in a non-patient population. Qualitative data synthesis and meta-analyses using a random-effects model were performed. Results: Of 4,184 articles identified, 47 were eligible for inclusion, involving approximately 1,200,000 participants. Studies were highly heterogeneous in terms of QoL measures, population characteristics and data analysis. In total, 43 studies (91.5%) reported that better QoL was associated with lower mortality risk. The results of four meta-analyses indicated that higher health-related QoL (HRQoL) is associated with lower mortality risk, which was consistent for overall HRQoL (HR 0.633, 95% CI: 0.514 to 0.780), physical function (HR 0.987, 95% CI: 0.982 to 0.992), physical component score (OR 0.950, 95% CI: 0.935 to 0.965), and mental component score (OR 0.980, 95% CI: 0.969 to 0.992). Conclusion: These findings provide evidence that better QoL/HRQoL was associated with lower mortality risk. The utility of these measures in predicting mortality risk indicates that they should be considered further as potential screening tools in general clinical practice, beyond the traditional objective measures such as body mass index and the results of laboratory tests.

Abstract
Background: Liver sinusoidal endothelial cells (LSECs) and Kupffer cells (KCs; liver resident macrophages) form the body´s most effective scavenger cell system for the removal of harmful blood-borne substances, ranging from modified self-proteins to pathogens and xenobiotics. Controversies in the literature regarding the LSEC phenotype pose a challenge when determining distinct functionalities of KCs and LSECs. This may be due to overlapping functions of the two cells, insufficient purification and/or identification of the cells, rapid dedifferentiation of LSECs in vitro, or species differences. We therefore characterized and quantitatively compared expressed gene products of freshly isolated, highly pure LSECs (fenestrated SE-1/FcgRIIb2+) and KCs (CD11b/c+) from Sprague Dawley, Crl:CD(SD), male rats using high throughput mRNA-sequencing and label-free proteomics.Results: We observed a robust correlation between the proteomes and transcriptomes of the two cell types. Integrative analysis of the global molecular profile demonstrated the immunological aspects of LSECs. The constitutive expression of several immune genes and corresponding proteins of LSECs bore some resemblance with the expression in macrophages. LSECs and KCs both expressed high levels of scavenger receptors (SR) and C-type lectins. Equivalent expression of SR-A1 (Msr1), mannose receptor (Mrc1), SR-B1 (Scarb1), and SR-B3 (Scarb2) suggested functional similarity between the two cell types, while functional distinction between the cells was evidenced by LSEC-specific expression of the SRs stabilin-1 (Stab1) and stabilin-2 (Stab2), and the C-type lectins LSECtin (Clec4g) and DC-SIGNR (Clec4m). Many immune regulatory factors were differentially expressed in LSECs and KCs, with one cell predominantly expressing a specific cytokine/chemokine and the other cell the cognate receptor, illustrating the complex cytokine milieu of the sinusoids. Both cells expressed genes and proteins involved in antigen processing and presentation, and lymphocyte co-stimulation. Conclusions: Our findings support complementary and partly overlapping scavenging and immune functions of LSECs and KCs. This highlights the importance of including LSECs in studies of liver immunity, and liver clearance and toxicity of large molecule drugs and nano-formulations.

Abstract
Background Undernutrition among under five children in India is a major public health problem.Despite India’s growth in the economy, the child mortality rate due to undernutrition is still high in both urban and rural areas.Studies that focus on urban slums are scarce. Hence the present study was carried out to assess the prevalence and determinants of undernutrition in children under five in Maharashtra, India.Methods A community-based cross-sectional study was conducted in 16 randomly selected clusters in two districts of Maharashtra state, India. Data were collected through house to house survey by interviewing mothers of under five children. Total 2929 mothers and their 3,671 under five children were covered. Multivariate logistic regression analysis was carried out to identify the determinants of child nutritional status seperately in urban and rural areas. Results The mean age of the children was 2.38 years (±SD 1.36) and mean age of mothers was 24.25 years (± SD 6.37).Overall prevalence of stunting among children under five was 45.9 %, wasting was 17.1% and 35.4% children were underweight.Prevalence of wasting, stunting and underweight were more seen in an urban slum than a rural area.In the rural areas exclusive breast feeding(p<0.001) and acute diarrhea (p=0.001) were associated with wasting, children with birth order 2 or less than 2 were associated with stunting and exclusive breast feeding (p<0.05) and low maternal education were associated with underweight. Whereas in the urban slums exclusive breast feeding(p<0.05) was associated with wasting, sex of the child (p<0.05) and type of family(p<0.05)were associated with stunting,and low income of the family(p<0.05) was associated with underweight.Conclusions Factors like sex of the child, birth order,exclusive breast feeding ,economic status of the family, type of family,acute diarrhea and maternal education have influence on nutritional status of the child. Improvement of maternal education will improve the nutritional status of the child. Strategies are needed to improve the economic status of the community.Trial registration- Registration number of the trial- CTRI/2017/12/010881; date of registration-14/12/2017.

Abstract
Background The insertion of Intrauterine Contraceptive Device (PPIUD) for the purpose of contraception immediately after delivery is becoming popular in countries where the use of IUD for contraception has been extremely low. Since 2015, Tanzania implemented the initiative by the International Federation of Gynecology and Obstetrics (FIGO) to institutionalize PPIUD. As a result of capacity building and information delivery under the initiative, there have been increased uptake of the method. Working in this context, the focus of the study was to generate evidence on the effect of TCu380A IUD on amount and duration of lochia and equip service providers with evidence-based knowledge which can help them in counselling their PPIUD clients. Objective Establish impact of postpartum TCu380A on amount and duration of lochia.Methods A prospective cohort study of delivered women in two teaching hospitals in Tanzania with immediate insertion of TCu380A or without use of postpartum contraception in 2018. TCu380A models; Optima (Injeflex Co. Brazil) and Pregna (Pregna International, Chakan, India) were used. Follow-up was done by weekly calls and examination at 6th week. Lochia was estimated by Likert Scale 0-4 relative to the amount of lochia on the delivery day. An estimated 250 women sample (125 each group) would give 80% power to detect a desired 20% difference in the proportion of women with prolonged lochia discharges among the Exposed and Unexposed groups. Data analysis was by SPSS. Results 275 women were analysed, 142 Exposed and 133 Unexposed. Medical complaints were reported by 41 (28.9%) Exposed and 37 Unexposed (27.8%), p=0.655. Lack of dryness by end of 6th week was to 32 (22.5%) Exposed and 8 (6.0%) Unexposed, p<0.001. Exposed had higher weekly mean lochia scores throughout with varience most marked in week 5 (F=3.818, p<0.001) and week 6 (F=2.949, p=0.004). Conclusion PPIUD is associated with increased amount of lochia and slows progression to dryness within 6 weeks of delivery. The implications of PPIUD clients’ need to be informed about the possibility of delayed dryness of lochia at the time of counseling are discussed.

Abstract
Background Regarding the importance of health literacy as a key factor in self-care, appropriate understanding of health information by patients with type 2 diabetes mellitus (T2DM) is fundamental for better management of risk factors, which can also benefit their quality of life. This study aimed to describe the relationship between health literacy (HL), and self-care behaviors with health-related quality of life (HRQL) in patients with T2DM.Methods A cross-sectional survey was done in Iran in 2019. Patients were recruited randomly from health centers by medical records (n= 192, 55.2% male, mean age 58.12 years). The data collection included demographic form, health literacy questionnaire, diabetes self-care behavior questionnaire, and world health organization’s Quality of Life-BREF (WHOQOL-BREF). Analyses were adjusted for confounders using hierarchical regression analysis.ResultsHL as predictor variables explained 47.5% of variance in overall HRQL (p-value< 0.001), reading health information was the strongest HL dimension (β= 0.478). Self-care behaviors explained an additional 13.6% of the HRQL variance. In total, 65.5% of the variation in the HRQL is explained by the HL, self-care behavior, and the demographic variables.Conclusions We found that more almost two-third of the HRQL explained by the HL and self-care behaviors. Given the importance of health literacy and self-care behaviors in the quality of life in patients with T2DM, adoption of health-promoting behaviors and increasing health literacy can be beneficial for promoting quality of life among these patients.

Abstract
Background: Stevia rebaudiana (Bertoni) is considered one of the most valuable plants because of the steviol glycosides (SGs) that can be extracted from its leaves. Glycosyltransferases (GTs), which can transfer sugar moieties from activated sugar donors onto saccharide and nonsaccharide acceptors, are widely distributed in the genome of S. rebaudiana and play important roles in the synthesis of steviol glycosides. Results: Six stevia genotypes with significantly different concentrations of SGs were obtained by induction through various mutagenic methods, and the contents of seven glycosides (stevioboside, Reb B, ST, Reb A, Reb F, Reb D and Reb M) in their leaves were considerably different. Then, NGS and single-molecule real-time (SMRT) sequencing were combined to analyse leaf tissue from these six different genotypes to generate a full-length transcriptome of S. rebaudiana. Two phylogenetic trees of glycosyltransferases (SrUGTs) were constructed by the neighbour-joining method and successfully predicted the functions of SrUGTs involved in SG biosynthesis. With further insight into glycosyltransferases (SrUGTs) involved in SG biosynthesis, the weighted gene co-expression network analysis (WGCNA) method was used to characterize the relationships between SrUGTs and SGs, and forty-four potential SrUGTs were finally obtained, including SrUGT85C2, SrUGT74G1, SrUGT76G1 and one SrUGT91D2, which have already been reported to be involved in the glucosylation of steviol glycosides, illustrating the reliability of our results.Conclusion: Combined with the results obtained by previous studies and those of this work, we systematically characterized glycosyltransferases in S. rebaudiana and forty-four candidate SrUGTs involved in the glycosylation of steviol glucosides were obtained. Moreover, the full-length transcriptome obtained in this study will provide valuable support for further research investigating S. rebaudiana.

Abstract
Background: Numerous studies on acute ischemic stroke (AIS) have been conducted at low-altitude regions, and the related findings have been used to guide clinical management. However, corresponding studies at high altitude are few. This study aimed to analyse the clinical characteristics of AIS patients at high-altitude regions through a hospital-based comparative study between Tibet and Beijing.Methods: This study included the diagnoses of AIS patients from People’s Hospital of Tibet Autonomous Region (PHOTAR) and Peking University First Hospital (PUFH) between 1 January 2014 and 31 December 2017, where data including patient demographics, treatment time, onset season, risk factors, infarction location, laboratory data, image examination results, treatments, and AIS subtype were collected and compared. Continuous and categorical variables were analysed with a two-sample t-test or Wilcoxon rank sum test and chi-square test, respectively. Significant risk factors were examined with binary logistic regression analysis.Results: In total, 236 and 1021 inpatients from PHOTAR and PUFH were included, respectively. The PHOTAR patients were younger than the PUFH patients (P<0.001). Young adult stroke, erythrocytosis, and hyperhomocysteinemia were more frequent in PHOTAR patients (all P<0.001). Other vascular risk factors, including hypertension, diabetes mellitus, hyperlipidaemia, and smoking and alcohol consumption history, were less prevalent in PHOTAR patients than in PUFH patients. The rate of intravenous thrombolysis and the rate of within intravenous thrombolysis window time were also lower in PHOTAR patients (both P<0.001). The PHOTAR group also tended to have anterior circulation infarction. Erythrocytosis and hyperhomocysteinemia were independent risk factors in PHOTAR, and young adults accounted for a larger proportion of stroke cases.Conclusion: In Tibet, AIS patients were relatively younger, and anterior circulation infarctions were more common. Erythrocytosis and hyperhomocysteinemia may contribute to these differences. Here, young adult stroke also accounted for a higher proportion, and this may be associated with erythrocytosis. Our findings present the first hospital-based comparative study in Tibet and may contribute to policies for stroke prevention in this region.

Abstract
Background: Malaysia has already achieved remarkable accomplishments in reaching zero indigenous human malaria cases in 2018. Prompt malaria diagnosis, surveillance and treatment played a key role in the country’s elimination success. Looking at the dynamics of malaria distribution during the last decades might provide important information regarding the potential challenges of such an elimination strategy. This study was performed to gather all data available in term of prevalence or incidence on Plasmodium infections in Malaysia over the last four decades.Methods: A systematic review of the published English literature was conducted to identify malaria distribution from 1980 to June 2019 in Malaysia. Two investigators independently extracted data from PubMed, Scopus, Web of Science and Elsevier databases for original papers.Results: The review identified 46 epidemiological studies in Malaysia over the 39-year study period, on which sufficient information was available. The majority of studies were conducted in Malaysia Borneo (31/46; 67.4%), followed by Peninsular Malaysia (13/46; 28.3%) and in both areas (2/46; 4.3%). More than half of all studies (28/46; 60.9%) were assessed by both microscopy and PCR. Furthermore, there was a clear trend of decreases of all human malaria species with increasing Plasmodium knowlesi incidence rate throughout the year of sampling period. The summary estimates of sensitivity were higher for P. knowlesi than other malaria species for both microscopy and PCR. Nevertheless, the specificities of summary estimates were similar for microscopy (40 – 43%) but varied for PCR (2 – 34%).Conclusions: This study outlined the epidemiological changes in Plasmodium species distribution in Malaysia. Malaria cases shifted from predominantly caused by human malaria to simian malaria, which accounted for the majority of indigenous cases particularly in Malaysia Borneo. Therefore, malaria case notification and prompt malaria diagnosis in regions where health services are limited in Malaysia should be strengthened and reinforced to achieving the final goal of malaria elimination in the country.
