Authors: Nabirye Rose Chalo , Kinengyere Alison Annet , Edwards Grace 
Published: June 2019

BACKGROUNDNurses and midwives form the backbone of health service delivery and satisfaction with care often depends on the competencies of nurses and midwives who provide the care (World Health Organization [WHO], 2002). Healthcare has become complex, challenging, and demanding across diverse sociocultural and socioeconomic changes and environments. To optimize their impact, nurses and midwives therefore need to be prepared with evidence-based competences. Nursing research therefore, is the cornerstone for evidence-based practice and for establishing the professional status of nursing and building research capacity. However, although nursing research began in the 19th century, it is limited in Africa, with little evidence generated to inform policy and practice. Although nursing and midwifery education in the region has advanced with graduate and postgraduate level education, little is known about nursing and midwifery research conducted in universities and where to find such research.OBJECTIVESThe literature review aimed at quantifying and identifying the types and gaps in nursing and midwives' research and publications in Africa.METHODSArticles published between January 1, 2007 and January 31, 2017 were retrieved from PubMed and Cumulative Index to Nursing and Allied Health Literature (CINAHL) with a search strategy that employed four sets of terms: (a) terms identifying published research done by nurses or midwives, or both; (b) terms identifying types of publications; (c) terms identifying filters for African countries; and (d) filters for publication dates. We also searched Google Scholar to capture nonindexed sources.RESULTS AND CONCLUSIONSThere is evidence of an increasing number of African nurses and midwives publishing research; however, much of this research may not be readily available. The promotion of nursing research and capacity building/mentorship in research for nurses and midwives is recommended to increase nurses' and midwives' skills to critically evaluate research and apply the best evidence to their practice.

Published: June 2019

PURPOSEGiven high neonatal mortality in many low- and middle-income countries, addressing missed opportunities by enhancing the quality of newborn care provided by facility-based nurses and midwives is critical. This scoping review synthesizes and critiques the literature on technology-based newborn health learning initiatives. Kirkpatrick's model is used for training program evaluation.METHODSA literature review was conducted from multiple databases. Articles selected for analysis consisted of original research studies published in peer-reviewed journals from 2012 to 2017.RESULTSTwelve studies fell into two categories: (a) Simulation training in routine neonatal care and newborn resuscitation (n = 9) and (b) eLearning initiatives (n = 3). Most studies evaluated health provider's knowledge and skills before and/or after training (n = 9); fewer evaluated the effect on change in provider practice (n = 3) and/or patient health outcomes (n = 5) (Kirkpatrick levels 3–4). Few studies utilized robust study designs and validated measurement instruments.CONCLUSIONLearning approaches emphasizing simulation training and eLearning initiatives for facility-based health workers hold promise. However, existing simulation literature demonstrates that translation of knowledge gained during simulation into improved clinical outcomes in real births is variable. Additionally, the volume of peer-reviewed evidence demonstrating the potential benefit of eLearning strategies, especially in the neonatal period, is limited.
Shareholder nationality among the major European and American defense contractors: an exploratory data analysis
Authors: FAWAZ Mahdi , BELIN Jean , MASSON Hélène 
Published: June 2019

This article presents the first results of a statistical analysis of the ownership links between the major European and American defence contractors. This approach, centred on the shareholders and subsidiaries of these companies, enables us to explore the depth of the national links (company and country of origin) and the density of the ownership cooperation that exists within Europe, as well as with the rest of the world, particularly the United States. Information about defence contractors’ ownership links is difficult to obtain and precautions must be taken in the interpretation of the results. In terms of defence contractor shareholders, it would appear first that the national link is strong for Sweden, Spain and France, less so for Germany and Italy, and particularly weak for the United Kingdom. Next, in European terms the links are concentrated on Airbus, MBDA and KNDS and are little developed in other companies. Finally, we observe asymmetrical links with the USA and a significant presence of American investment funds.

New Analytical Model Enhances Understanding of Connection Strengths
Authors: Feder Judy 
Published: June 2019

This article, written by JPT Technology Editor Judy Feder, contains highlights of paper SPE 194180, “An Analytical Model for Double-Shouldered Connection Strengths,” by Grant Pettit, SPE, Bureau Veritas, prepared for the 2019 SPE/IADC International Drilling Conference and Exhibition, The Hague, 5–7 March. The paper has not been peer reviewed.
The extra torsional capacity and clearance available when proprietary, double-shouldered connections are used instead of public-domain, single-shouldered connections enables well teams to drill farther, faster, and with less damage to the drillstring. No analytical model as yet can accurately calculate the tensile and torsional capacities of double-shouldered connections. This paper presents a set of equations that extends the approach of the original single-shouldered equation to account for a second shoulder, and helps to understand connection strengths better.
Introduction
Single-shouldered connections such as API drillstem connections use a straightforward analytical equation to determine the capacities of any connection. This equation may not be perfect—it relies on linear assumptions that are probably not descriptive of the connection loading—but several decades of use have made the industry confident in the equation’s strengths and aware of its shortcomings.
Because no analytical model is available to calculate these capacities in proprietary double-shouldered connections, the connection designer or manufacturer typically creates an empirical formula that is calibrated through laboratory and field testing. Although this approach is acceptable, it hinders tool designers who need something different from what is offered on the public market. It is rarely cost-efficient to perform laboratory and field testing for a one-off connection design.
The complete paper states that what is needed is to extend the approach of the original single-shouldered equation to account for a second shoulder. According to the author, although the mathematical complexity increases, the assumptions are the same, lending confidence to the extended equation.
The complete paper presents the derivation of a set of equations that use the same basic assumptions as the original single-shouldered connection torque equations, in the same way as do the API equations, to advance understanding of the torsion and tension capacities for double-shouldered equations. The implicit assumptions present in the original equations are discussed; then the same ideas are applied to a double-shouldered connection. The full set of new equations is developed and described, including tips on their practical use gained from tool-design experience.
Current Single-Shouldered Connection Model
Connection strength formulas contained in API RP 7G Appendix A are the basis for the connection torsion and tensile capacities in that standard and in many other oilfield references. These equations and resulting numbers have been in place for decades, creating industry confidence in their usefulness and awareness of their weaknesses.
Technology Focus: CO2 (July 2019)
Authors: Kokal Sunil 
Published: June 2019

Technology Focus
In my last two Technology Focus columns, I discussed CO2-enhanced oil recovery (EOR) and the challenges it faces in conventional oil reservoirs. In this entry, my focus is on its applications in unconventional reservoirs.
Oil and gas production from unconventional resources has changed the dynamics of the world oil supply, particularly in the US. This has changed the US from a declining oil producer to one of the highest oil producers in the world. Oil production from unconventional reservoirs is still a challenge and depends on a number of factors, including brute force, for drilling and hydraulic fracturing. Production from these reservoirs declines rapidly, and more wells have to be drilled to keep production at reasonable levels. Recovery, by some estimates, can be less (sometimes much less) than 10%. Currently, the number of wells drilled in unconventional reservoirs exceeds 100,000, and many are producing just a trickle of hydrocarbons.
In recent years, some effort has been made to use EOR techniques, particularly CO2 injection, to extract additional oil and gas from unconventional resources. This is by no means a trivial feat. It has the potential to change the dynamics (again) of oil production from these tight and difficult reservoirs.
Considerable research and laboratory studies have been conducted addressing the use and potential of CO2 in extracting hydrocarbons from unconventional reservoirs. Estimates of oil recovery range from an additional 10% up to more than 50%. Very few field trials have been conducted, but the use of CO2 in these reservoirs is promising.
The recommended papers that follow present examples of laboratory studies, taking the results to the field, and mechanistic studies that elucidate some of the factors to consider and the pros and cons of CO2-EOR in unconventionals. They are meant to be a starting point for better understanding and further research. What the industry needs at this stage is more-daring EOR field trials reminiscent of the risks taken by the pioneers of unconventional resources at the beginning of this century.

The Feasibility of CO2 Injection for IOR in Shale Reservoirs
Authors: Feder Judy 
Published: June 2019

This article, written by JPT Technology Editor Judy Feder, contains highlights of paper SPE 190277, “Mechanistic Study for the Applicability of CO2-EOR in Unconventional Liquids-Rich Reservoirs,” by Dheiaa Alfarge, SPE, Iraqi Ministry of Oil and Missouri University of Science and Technology, and Mingzhen Wei and Baojun Bai, Missouri University of Science and Technology, prepared for the 2018 SPE Improved Oil Recovery Conference, Tulsa, 14–18 April. The paper has not been peer reviewed.
Improved oil recovery (IOR) methods for shale-oil reservoirs are considered relatively new concepts compared with IOR for conventional oil reservoirs. Different IOR methods—including CO2, surfactant, natural gas, and water injection—have been investigated for unconventional reservoirs using laboratory experiments, numerical simulation studies, and limited pilot tests. For a variety of reasons, CO2 injection is the most-investigated option. In this paper, numerical simulation methods of compositional models were incorporated with logarithmically spaced, locally refined, and dual-permeability reservoir models and local grid refinement (LGR) of hydraulic-fracture conditions to investigate the feasibility of CO2 injection in shale oil reservoirs.
Introduction
Advancements in horizontal drilling and hydraulic fracturing enabled unconventional liquids-rich reservoirs (ULRs), such as shale and source-rock formations and very tight reservoirs, to change the oil industry. ULRs are characterized by pore throats of micro- to nanomillimeters and an ultralow permeability. Although different studies re-ported that these ULRs contain billions of recoverable oil barrels in place, it is estimated that less than 7% of the original oil in place can be recovered during the primary depletion stage. Production sustainability is the main problem behind the low oil recovery in these unconventional reservoirs. Oil wells in ULRs typically start with a high production rate, but show a steep decline rate in the first 3–5 years of production life because of the rapid depletion in the natural fractures combined with a slow recharge from the rock matrix.
The logical steps of academic research such as experimental investigation, simulation studies, and pilot tests for examining the applicability of different unconventional IOR methods have just begun in the past decade. Applying one of the feasible IOR methods in most oil and gas reservoirs should be mandatory to increase the oil-recovery factor. However, the mechanisms of IOR methods in unconventional reservoirs are not necessarily the same as those in conventional reservoirs. The primary characteristics of unconventional reservoirs that might impair performing IOR operations are low porosity and ultralow permeability. As a result, finding IOR methods that are insensitive to these very small pore throats is a priority.
Passive exercise in a multisensory environment in order to manage adverse effects in physically inactive patients with dementia: a randomized controlled trial
Authors: Heesterbeek Marelle , Zee Eddy van der , Fuermaier Anselm , Heuvelen Marieke van 
Published: June 2019

Abstract
Background

Since pharmacological treatments to manage dementia remain controversial, development of non-pharmacological alternatives to limit adverse effects of dementia is urgently needed. Passive exercise in a multisensory environment (Therapeutic Motion Simulation (TMSim, Whole Body Vibration (WBV) and a combination (TMSim + WBV)) is proposed to be such a non-pharmacological alternative. This study primarily aimed to investigate the effects of these different forms of passive exercise on Quality of Life (QoL) and Activities of Daily Living (ADLs) of inactive institutionalized patients with dementia. The secondary aim was to assess the effects on cognitive and physical function.

Methods

In this randomized controlled trial 120 inactive institutionalized persons with dementia (age 85.3 ± 6.8 years, 64.5% female, 59.2% walking aid/wheelchair users, mini mental state examination 12.9 ± 6.6) were assigned to TMSim, WBV, TMSim + WBV or a control group (regular care) The passive exercise groups followed a six-week intervention program consisting of four 4–12 minute sessions a week. QoL, ADLs (proxy-report questionnaires), cognitive and physical function (performance based tests) were measured at baseline, after 6 weeks of intervention, and 2 weeks after the intervention had ended.

Results

Outcome measures did not differ between groups at baseline. No consistent effects of passive exercise on QoL, ADLs, cognitive and physical function were observed after six weeks of intervention or during follow-up.

Conclusion

In the current setting passive exercise did not affect any of the outcomes measures. This may be due to the short intervention period, limited sensitivity to change of the assessment instruments in this specific vulnerable population or short lasting effects of the interventions. Future research into passive exercise should consider measuring acute and short term effects as well as longer intervention periods looking into alternative outcome measures (e.g. seated balance and behavioral and psychological symptoms of dementia).

Abstract
Background: Vascular hypo-responsiveness to vasopressors in patients with obstructive jaundice (OJ) is a common anesthetic event, which leads to perioperative complications and increased mortality. The cause of this clinical issue remains unclear. Here, changes in the artery of OJ patients were assessed by proteomic analysis. Methods: Ten patients with OJ due to bile duct or pancreatic head neoplasms were enrolled, alongside ten chronic cholecystitis or liver hemangioma cases forming the controls group. Vascular reactivity was measured before anesthesia on the day of surgery. Artery samples near or surrounding the removed tumor tissues were collected and evaluated by 2-dimensional electrophoresis. Proteins with differential expression were detected by MALDI-TOF mass spectrometry, with immunoblot confirmation. Results: Vascular hypo-reactivity in OJ cases as well as suppressed aortic response to vasoactive products were evidenced. We also found that actin cytoskeleton and several actin-binding proteins were up- or down-regulated in the artery of OJ patients. Conclusion: The newly detected regulated proteins prompt future functional investigations to unveil the mechanisms of vascular hypo-reactivity in patients with obstructive jaundice.

Abstract
Cardiovascular diseases (CVD) are the leading cause of mortality globally, responsible for 31% of all global deaths. This study highlights the prevalence and risk distribution of CVD in persons with type 2 diabetes in a rural population, the effect of glucose control in persons with diabetes, and the gender difference of diabetes impact on CVD occurrence.

This study utilized baseline data from the Henan Rural cohort study. In all, 39184 participants with complete data were included in the present analysis. Logistic regression models were used to assess the association between diabetes and cardiovascular events.

Diabetes was prevalent among the study participants (nearly 10%; 42% of persons with diabetes were undiagnosed). About10% of the participants had experienced a cardiovascular event before; persons with diagnosed diabetes were three times more likely to have experienced a cardiovascular event (OR=2.80, 95% CI: 2.51-3.12) compared to those without diabetes. There was a gender difference in the prevalence of CVD events, with more men experiencing a cardiovascular event; however, women with diagnosed diabetes were1.5 times more likely to have experienced a stroke compared to men. There was no association between glucose control and CVD in the subgroup of diagnosed diabetes. Persons with glucose control were at increased odds of a stroke event compared to those with no glucose control in the diagnosed diabetes group.

Diabetes is strongly associated with CVD in our study population; women with diabetes are at increased risk of suffering a stroke. Glucose control was not associated with previous CVD history.

Abstract
Physical interactions mediated by proteins are a critical element of biological systems, and the analysis of interaction partners can provide valuable hints about unknown functions of a protein. Two major classes of experimental approaches are used for protein interaction mapping: analysis of direct interactions using binary methods such as yeast two-hybrid (Y2H) or split ubiquitin, and analysis of protein complexes through affinity purification followed by mass spectrometry. Thanks to his flexibility to low- and high-throughput approaches and a low operating cost the Y2H assay is widely used for high-throughput interaction mapping experiments. Moreover, it has now been shown that high-throughput methods can produce highly reliable interactome datasets1 2 3 4. Notably, in 2011 a proteome-wide binary protein-protein interaction map of the plant Arabidopsis thaliana 5 (Arabidopsis Interactome Mapping project – AIM) was described using a high-throughput binary interactome mapping pipeline based on the Y2H system and using a collection of ~8,000 open reading frames (8k_space). Here we describe a liquid pipeline for a high-throughput binary protein–protein Y2H screen of a pool of 50 proteins used as baits against a collection of ~12,000 Arabidopsis proteins encoded by sequence-verified ORFs (12k_space)6 7.
