Authors: Brown Matthew , Wiltshire William , de Sa Leitao Pinheiro Fabio Henrique , Schönwetter Dieter J.
Published: February 2022

Objectives

To evaluate orthodontists' perceived impacts on their practices as a result of general practitioners (GPs) and direct-to-consumer (DTC) orthodontic care providers and the adaptational changes implemented in the past 10 years.

Materials and Methods

An electronic survey was administered to 270 orthodontists in Canada and the United States to determine demographic background, perception of perceived impact, and specific changes implemented to improve practice competitiveness.

Results

More experienced orthodontists (P = .0001) and males (P = .027) were more likely to indicate a perceived impact from GP orthodontics. American orthodontists were significantly more likely than Canadian orthodontists to perceive an impact from DTC providers (P = .017). There was a positive association with orthodontists' years of experience and having implemented adaptational changes to their practice for a period greater than 10 years across multiple categories. Female orthodontists were more likely to have implemented adaptational changes for a period of less than 10 years across multiple categories.

Conclusions

The perceived impact of GPs providing orthodontic care was greater than that of DTC providers. American orthodontists were significantly more likely to perceive an impact from DTC providers. Orthodontists have experienced a reduction in referrals from GPs and an increase in referred case difficulty. Less experienced and female orthodontists have made the most adaptive changes to their practices in the past 10 years.

Yersinia pestis antibiotic resistance: a systematic review
Authors: Lei Chen , Kumar Suresh
Published: February 2022

Yersinia pestis, the cause of plague and a potential biological weapon, has always been a threatening pathogen. Some strains of Y. pestis have varying degrees of antibiotic resistance. Thus, this systematic review was conducted to alert clinicians to this pathogen’s potential antimicrobial resistance. A review of the literature was conducted for experimental reports and systematic reviews on the topics of plague, Y. pestis, and antibiotic resistance. From 1995 to 2021, 7 Y. pestis isolates with 4 antibiotic resistance mechanisms were reported. In Y. pestis 17/95, 16/95, and 2180H, resistance was mediated by transferable plasmids. Each plasmid contained resistance genes encoded within specific transposons. Strain 17/95 presented multiple drug resistance, since plasmid 1202 contained 10 resistance determinants. Strains 16/95 and 2180H showed single antibiotic resistance because both additional plasmids in these strains carried only 1 antimicrobial determinant. Strains 12/87, S19960127, 56/13, and 59/13 exhibited streptomycin resistance due to an rpsl gene mutation, a novel mechanism that was discovered recently. Y. pestis can acquire antibiotic resistance in nature not only via conjugative transfer of antimicrobial-resistant plasmids from other bacteria, but also by gene point mutations. Global surveillance should be strengthened to identify antibiotic-resistant Y. pestis strains by whole-genome sequencing and drug susceptibility testing.

The reason for this study was to compare the morphology of mites from three Japanese samples with topotypes from the Nalepa collection, in order to correctly identify them. With this purpose eriophyoid specimens were recovered from five vials of the Nalepa mite collection in the Natural History Museum of Vienna. We identified seven species and a new combination is established for one of them - Aceria thomasi and Aculops thymi, from two vials labeled Thymus serpyllum (Lamiaceae); Eriophyes spiraeae from a vial labeled Spiraea crenifolia (Rosaceae); and Peralox longirostris n. comb., Shevtchenkella ulmi, Aceria filiformis and Aculus mastigophorus from two vials labeled Ulmus campestris (Ulmaceae). A supplementary description is presented for these species. The Japanese samples were collected from ‘Shiso’, Perilla frutescens var. crispa (Lamiaceae), from Spiraea thunbergia (Rosaceae) and from Juglans mandshurica (Juglandaceae). The mites collected from ‘Shiso’ were identified as A. thymi, but the other two Japanese samples did not match the topotypes. These two samples may be new species and require further taxonomic studies.

Published: February 2022

Ischemic stroke is a condition resulting from a lack of blood flow to the brain. One of the therapies used for ischemic stroke is antiplatelet. Single antiplatelet therapy is generally preferred over combination antiplatelet therapy, because combination therapy results in increased bleeding, which outweighs any benefits. Various studies on the effectiveness of antiplatelet between the combination of aspirin and clopidogrel with aspirin in ischemic stroke patients have been carried out. However, until now there is no consensus that the outcome is better between single aspirin therapy with the aspirin-clopidogrel combination. The aim of this study was to compare the effectiveness of the combination aspirin-clopidogrel and aspirin in ischemic stroke. The method used in this study is a literature review using Google Scholar, PubMed, and Science Direct databases. From the 5 literature that has been reviewed, it shows that in patients with minor ischemic stroke the combination of aspirin-clopidogrel is more effective than single aspirin which is seen from several parameters including Modified Rankin Scale (mRS), European Quality of Life – 5 Dimension (EQ-5D), National Institute of Health Stroke Scale (NIHSS), Activated Partial Thromboplastin Time (aPTT), leukocyte platelet aggregation and leukocyte-platelet aggregate.

Este artículo de investigación expone los principales aspectos de la sistematización de experiencias: el impacto del proyecto educativo institucional del INPEC en un grupo de mujeres pospenadas, como medio para reflexionar sobre la relación de la educación penitenciaria y los procesos de resocialización. El objetivo general de este escrito es sistematizar una experiencia en el campo de la educación penitenciaria para visibilizar y reflexionar sobre los impactos del proyecto educativo del INPEC en la cualificación de un grupo de mujeres pospenadas. Se enfoca el tipo de investigación a través del paradigma sociocrítico que se caracteriza por una continua acción-reflexión-acción, desarrollado mediante el método de sistematización de experiencias educativas. Los principales hallazgos permiten ver que los modelos educativos penitenciarios están supeditados a una serie de factores que influyen en el diseño organizacional, el establecimiento, la administración y la gobernanza. Además, que las condiciones de vida en una prisión se encuentran entre los principales factores que determinan la potenciación del ser humano que cumple una condena; en ese sentido, la autoestima y la dignidad con las que se les trata en el centro penitenciario delimita la posibilidad del PPL de tener éxito en el proceso de reintegrarse a la sociedad como ciudadano respetuoso de la ley.

Authors: Hashmi M. Asef
Published: February 2022

Well was drilled in Al Nouf field with the objective to support the pressure sustainability of multiple producer wells across Shuaiba-1 formation based on MRC / ERD approach. This paper presents the challenges faced in planning and drilling of subject well and successfully running of slim lower completion to total measured depth of 21,000ft (6.4 km) with having horizontal section of 10,450ft (3.18 km) with directional difficulty index (DDI) of 6.520 using slim casing design.

Planning of this well commenced by meetings and collaboration with subsurface operation and reservoir team with the common objective of drilling a well of over 11,000ft horizontal extent and having a capability of running 4 ½" pre-perforated liner with multiple swell packers as lower completion to well TD of (21,000ft) across Shauiba - 1 reservoir. Purpose of lower completion are to properly control the well injectivity regime and support multiple producers across SH-1.

All the associated risks were highlighted and mitigated by proper planning and engineering analysis such as trajectory, collision risks, BHA, hydraulics and casing design.

This MRC injector well of 21,000ft MD / 8953 ft TVD (2.34 ERD H:V ratio) is the first well in the region to have 11,000ft of geo-steered 6" horizontal section with slim lower completion installed till TD of well.

This paper will explain the innovative approach of mitigating the challenges faced while drilling a complex well of 3500ft departure and have a horizontal section of over 11,000ft with 6" drainage. A few challenges like collision risk at surface & horizontal section with total losses across aquifer were major disquiet but successfully catered. Second major challenge was to run 4 ½" pre-perforated liner of 11,000ft with multiple swell packers (each 1000ft) to TD of well were immaculately mitigated with advanced engineering analysis and innovative technologies like swivel master etc.

Results from this well have proven that having lower completion in MRC / ERD wells have significantly improved the well accessibility and well performance and enhanced the reservoir management and significantly reduced the field development cost.

This paper summarizes the practice and technology used to drill successfully the MRC / ERD well in artificial island and running of slim lower completion across horizontal section till TD of well.

The challenges and its mitigation explained in this paper will support the idea of having lower completion in MRC/ERD wells which helps to stretch the reservoir boundaries and have more control on injectivity / productivity of reservoir because of proper isolation by swell packers and have maximum well accessibility across ERD horizontal section.

As the oil and gas business progresses and rapidly moves to an Automation and Digital "ERA", a wide array of initiatives have been launched in pursuit of increased performance. In a demanding Deep Gas Carbonate well project in the Middle East, seven years of continuous improvement has led to a variety of technology implementations which have dramatically affected operational efficiency and drilling performance. The opportune selection and implementation of new technology and optimized practices has contributed to a significant increase in the project team's ability to exceed one of the Operator's main key performance indicators: well delivery. In this paper, a summary will be provided of the digital and automation solutions implemented to standardize drilling procedures, drill pipe connections, optimize the rate of penetration, reduce downhole shocks and vibrations, all while minimizing drill string failures.

New technologies were implemented to optimize the operation without compromising well operations. Part of the success in reducing failures and non-desirable events, has resulted from the enhancement of the Real Time Monitoring resources available, through the implementation of different digital technologies, including hole cleaning monitoring, drilling fluid property controls, cementing operations monitoring, and algorithms utilized to infer the displacement plug position over the well.

Development of giant offshore carbonate field with more than 400 oil producers and 300 water injectors are very complex without proper production optimization tool to reach sustainable production and optimize the cost of the investment for future development. Construction of IAM model for short term optimization purposes brings vital outcomes which can identify the short and long term optimizations scenarios and as a consequences reduce the investment with the maximum outcome of production within the reservoir management guidelines of the field.

Integrated asset modelling tool (PSO-production system optimization tool Prosper+Gap) is ideal tool which can provide the best production optimization results to develop the giant field with all reservoir guidelines and production system bottleneck.

One of the main achievement of integrated asset model (PSO) for a giant carbonate oil field is the fact that its fully compositional model which allows to track oil composition change at any point of the surface facility, which is critical for fields under secondary recovery mechanisms with water and gas injection.

Great efforts are invested in improving oil and gas reservoir recovery to meet the rise in local energy consumption and global demand. To improve the production and ultimate recovery of a major oil field in the Middle East, extended-reach drilling (ERD) is executed in wells with long horizontal multilaterals to achieve maximum reservoir contact (MRC), the increase in ERD wells demand led to many drilling challenges and difficulties.

The challenges in designing ERD wells are multiple, such as trajectory control, well collision avoidance, hole cleaning efficiency, high torque & drag, differential sticking, wellbore stability, Logging-while-drilling (LWD) log quality and long circulating hours. In recognition of this, the dedicated operator and service team developed a drilling optimization roadmap that addresses the drilling challenges at the greatest performance impact. The optimization roadmap comprises enhanced trajectory design, drillstring design, drilling fluids and system hydraulics design, and subsurface geomechanical modelling in the planning phase, in addition to realtime formation evaluation, hole cleaning and torque and drag monitoring, and drillstring vibrations management in the execution phase.

The exploitation of 4 inch and 5 inch tapered drillstring as opposed to complete 5 inch drillstring for drilling torque reduction and its related tripping behavior was explored on the first Optimization stage of the optimization plan, using this approach successfully reduced drilling torque, but the tripability out of hole became problematic and more difficult. The first stage outcome called for utilizing complete 5 inch drillpipe string in addition to oil-based mud (OBM) lubricant (OMNI-LUBETM) that resulted in 20-25% reduction of the drilling torque. Tripability improved compared to 4 inch drill pipe in the second optimization stage, but still facing some issues in few laterals. On the final optimization stage, the engineering & operations team introduced the Dog Leg Reamer tool on top of the drilling bottomhole assembly (BHA) which resulted in a significant improvement in the tripping behavior in addition to a smoother hookload along in the drilled interval. The implementation of the holistic drilling system design and optimization methodologies helped achieving new performance records, lateral after lateral. The optimization roadmap delivered a proven performance in the most challenging drilling environments.

The key technical challenges, performance optimization roadmap, job execution, and post well evaluation of the drilling performance are presented in this paper.

Direct feedback from the drilling process will be key to enhance overall drilling performance further, improve steering and will help detect drilling dysfunctions early. This is especially true for demanding drilling applications, such as drilling in difficult geological formations. Faults, hard stringers or borehole instabilities can have a negative impact on rate of penetration (ROP) or even worse can damage equipment and cause non-productive time (NPT). This gets pronounced for extended reach drilling, where long drill strings delay the received feedback from the drilling process or effects along the drill string (e.g friction) skew the results.

To overcome these obstacles a near bit sensor was developed to provide real time weight-on-bit (WOB), torque-on-bit (TOB), bending and bending orientation data. It is directly integrated into the steering unit of the rotary steerable system (RSS) with the goal to be simplistic, cost efficient and robust. To discuss potential uses and limitations of the load sensor, the basic design and operational principle are shown.

Different usage scenarios of the system are presented in theoretical terms and backed by real-world data. One scenario is the possibility to diagnose reasons for low ROP, for instance weight transfer issues can be distinguished from bit damages if WOB and TOB real time data is available. For early detection of unwanted deflections in directional drilling, for instance due to faults or tilted beds, near bit bending and bending orientation measurements of the RSS system can be used.

The near bit sensor design proves to be reliable and cost efficient. It shows high potential to increase ROP and reduce NPT and overall drilling cost.
