Published: May 2018

Background:
The Hirsch index (h-index) quantifies research publication productivity for an individual, and has widely been considered a valuable measure of academic influence. In 2010, the Physician Payments Sunshine Act (PPSA) was introduced as a way to increase transparency regarding U.S. physician-industry relationships. The purpose of this study was to investigate the relationship between industry payments and academic influence as measured by the h-index and number of publications among orthopaedic surgeons. We also examined the relationship of the h-index to National Institutes of Health (NIH) funding.

Methods:
The h-indices of faculty members at academic orthopaedic surgery residency programs were obtained using the Scopus database. The PPSA web site was used to abstract their 2014 industry payments. NIH funding data were obtained from the NIH web site. Mann-Whitney U testing and Spearman correlations were used to explore the relationships.

Results:
Of 3,501 surgeons, 78.3% received nonresearch payments, 9.2% received research payments, and 0.9% received NIH support. Nonresearch payments ranged from $6 to $4,538,501, whereas research payments ranged from $16 to $517,007. Surgeons receiving NIH or industry research funding had a significantly higher mean h-index and number of publications than those not receiving such funding. Surgeons receiving nonresearch industry payments had a slightly higher mean h-index and number of publications than those not receiving these kinds of payments. Both the h-index and the number of publications had weak positive correlations with industry nonresearch payment amount, industry research payment amount, and total number of industry payments.

Conclusions:
There are large differences in industry payment size and distribution among academic surgeons. The small percentage of academic surgeons who receive industry research support or NIH funding tend to have higher h-indices. For the overall population of orthopaedic surgery faculty, the h-index correlates poorly with the dollar amount and the total number of industry research payments. Regarding nonresearch industry payments, the h-index also appears to correlate poorly with the number and the dollar amount of payments. These results are encouraging because they suggest that industry bias may play a smaller role in the orthopaedic literature than previously thought.

Published: May 2018

Background:
Optimizing the perioperative care of patients with a hip fracture is a key health-care priority. We aimed to determine whether adherence to the Scottish Standards of Care for Hip Fracture Patients (SSCHFP) was associated with improved patient outcomes.

Methods:
In this retrospective cohort study of prospectively collected data from the Scottish National Hip Fracture Audit, we assessed adherence to the SSCHFP in 21 Scottish hospitals over a 9-month period in 2014 and examined the effect of the guidelines on 30 and 120-day mortality, length of hospital stay, and discharge destination.

Results:
A total of 1,162 patients who were ≥50 years old and admitted with a hip fracture were included. There was a significant association between low adherence to the SSCHFP and increased mortality at 30 and 120 days (odds ratio [OR], 3.58 [95% confidence interval (CI), 1.75 to 7.32; p < 0.001] and 2.01 [95% CI, 1.28 to 3.12; p = 0.003], respectively). Low adherence was associated with a reduced likelihood of a short length of stay (OR, 0.58; 95% CI, 0.42 to 0.78; p < 0.0001), but increased odds of discharge to a high-care setting (OR, 1.63; 95% CI, 1.12 to 2.36; p = 0.01). Early physiotherapy input and occupational therapy input were associated with a reduced likelihood of discharge to a high-care setting (OR, 0.64 [95% CI, 0.44 to 0.98; p = 0.04] and 0.34 [95% CI, 0.23 to 0.48; p <0.001], respectively).

Conclusions:
Adherence to the SSCHFP is associated with better patient outcomes. These findings confirm the clinical utility of the SSCHFP and support their use as a benchmarking tool to improve quality of care for hip fractures.

Cervical Facet Orientation Varies with Age in Children
Authors: Pesenti Sebastien , Lafage Renaud , Lafage Virginie , Panuel Michel , Blondel Benjamin , Jouve Jean-Luc 
Published: May 2018

Background:
Within the spine, mobility and stability are principles that drive anatomic morphology. Based on radiographic measurements, the orientation of cervical facet joints has been proven to change throughout child growth. However, because of the mainly cartilaginous composition of the vertebrae in the young child, the lack of osseous landmarks makes radiograph-based measurements unreliable. The aims of our study were to evaluate the change in the sagittal orientation of the cervical facet joints with age based on magnetic resonance imaging (MRI) of asymptomatic children and to compare it to the changes in vertebral body dimensions.

Methods:
Sagittal images passing through the center of the facet joint or through the center of the vertebral body were used to assess facet orientation at every cervical level. Anteroposterior facet orientation was defined as the angle between the superior facet and a line perpendicular to the posterior wall of the vertebral body. Vertical was defined as parallel to the posterior wall; horizontal was defined as perpendicular to the posterior wall. Vertebral body height and anteroposterior diameter were measured as well.

Results:
MRI data of the normal cervical spine of 90 children who were 2 months to 18 years of age, obtained for neurologic evaluation, were used for this study. For each level from C3 to C7, there was a positive correlation between facet orientation and age (R = 0.498, p < 0.001). The facet joints were the most vertical at C3 (43.9°) and C7 (49.6°), whereas C5 had the most horizontal facets (39.4°). The greatest rate of change in facet orientation was observed between 6 and 9 years of age.

Conclusions:
Our results demonstrate that facets become more vertical as a function of age. However, other parameters than age must be considered to explain the variation of facet orientation. At C3 and C7, the facet orientation was more vertical, which may increase stability. In between, C5 facets were shallower, which may increase mobility and flexion-extension range of motion.
Sixty Years On: Ponseti Method for Clubfoot Treatment Produces High Satisfaction Despite Inherent Tendency to Relapse
Authors: Zionts Lewis E. , Ebramzadeh Edward , Morgan Rebecca D. , Sangiorgio Sophia N. 
Published: May 2018

Background:
Developed at the University of Iowa in 1950, the Ponseti method to manage idiopathic clubfoot deformity was slow to gain wide acceptance until the mid-1990s. There is a paucity of intermediate and long-term outcome studies involving this technique, with nearly all such studies coming from a single institution. The purpose of this study is to report the contemporary outcome of patients with clubfoot deformity whose feet were managed with the Ponseti method and who were followed to ≥5 years old, to provide outcome expectations for parents and for clinicians managing patients with idiopathic clubfoot.

Methods:
Families of infants seen in our clinic diagnosed with idiopathic clubfoot since July 2006 were prospectively invited to participate in our institutional review board-approved study. Patients who received no prior outside treatment and had a minimum follow-up to the age of 5 years were included. Demographic, treatment, and outcome data were collected. To provide an array of outcome measures, both the Dallas outcome criteria and the Roye disease-specific instrument (DSI) were used.

Results:
One hundred and one patients met the inclusion criteria. The mean length of follow-up (and standard deviation) was 81.1 ± 17.1 months. Initial correction was achieved in all feet. Thirty-seven percent of families reported that they were adherent with the bracing protocol; 68% of patients had ≥1 relapse, and 38% underwent a tendon transfer. With the Dallas criteria, 62% had outcomes rated as good, 38% had outcomes rated as fair, and no patient had an outcome rated as poor. With the Roye DSI, most families were generally very satisfied with the function and appearance of the feet.

Conclusions:
Satisfactory results at intermediate follow-up were achieved using the Ponseti method. However, despite a better understanding of the Ponseti method and the importance of longer post-corrective brace use, the need for anterior tibial tendon transfer remains an important adjunct to the Ponseti method. Brace adherence also continues to be a critical clinical issue.

I’m sure you’ve seen it very obviously happening all around us. Yet, looking at the details still surprises. While reviewing the papers published in the intelligent-fields area this year, I was struck by the contrast I saw compared with just 3 years ago. Novel and niche are giving way to systemic and pervasive. What only recently was the domain of academics and research types with larger operators and service companies has broadened to an amazing diversity of practitioners.
The papers mirror what I see and hear in many of the companies I interact with. Yes, our companies have hired more people with formalized training in data science, but what I find impressive is the number of people who were hiding in normal discipline jobs only a few years ago who are coming out of the closet with their Python scripts. And, it’s working. In many ways, order is coming to the mess, efficiency is coming to tiresome manual activities, and richness is coming to our decisions.
So, what changed that we are more rapidly seeing the promised progress?
I associate much of the acceleration to what I would call an open-source mentality, an approach that prefers to find an appropriate, available solution that is easily accessible, rather than developing or buying something fit-for-purpose. “There’s an app for that” has evolved to marketplace models, not only on your smart phone but also now in the Jupyter notebook on your desktop or in the marketplace of your cloud environment. As a result, or perhaps as a driving part of the changes, tech giants such as Amazon and Microsoft are finding their part in the energy sector by providing convenient and efficient marketplaces sup-porting integration of open-source and proprietary technologies. Smaller companies and startups can deliver low-cost solutions to such environments, and cooperative developments such as the Open Earth Consortium will bring further efficiencies by delivering standard oil-and-gas-specific frameworks. Instead of armies of developers delivering the next generation over 5 or 10 years, a capable community is emerging that can deliver a multitude of small advances that build on synergies of existing capabilities.
I hope to see you at the SPE workshop on Smart Integration in Production System Modeling on 19–20 June in Galveston, Texas, USA.
Technology Focus: Multilateral/Extended-Reach Wells (May 2018)
Authors: Aadnøy Bernt S. 
Published: May 2018

Technology Focus
The ultimate challenge for the oil industry is to drain the reservoirs completely. The average recovery factor is still only 50% in Norway, for example, despite considerable research and development in the past decades. Much more oil remains, leaving us with considerable potential for increased recovery.
Drilling wells to access the remote parts of the reservoirs is a key factor in this, but many wells may prove uneconomical, so fewer extended-reach wells are often chosen. For the past 15 years, many wells have been drilled with step outs of 30,000–40,000 ft. Going beyond this is not simple because using conventional technology has limits related to hydraulics, materials, and other technical challenges and also carries a high economic risk. Recently, the world’s longest well was drilled in Sakhalin, Russia, with a total depth of 49,200 ft and a step out of 46,300 ft.
Current long-reach technology already has a large effect on oil recovery. Many possible improvements, however, remain, and we see new contributions every year. One example is given in paper SPE 186917, which shows developments within drill-in fluids. Paper OTC 28091 demonstrates a record horizontal well drilled in Brazil. Other people are challenging the maximum well length; paper SPE 178859 presents an entirely new drilling concept with the objective of more than doubling well stepout.
Along with drilling development, the completions of these wells have also improved, with a considerable number of inflow-control technologies, smart-well completions, and fishbone drain-age systems, for example. The completion string is designed to optimize the production of the well and minimize negative effects on water production, important elements for maximizing the recovery factor. Extended-reach wells will be improved continuously to ensure maximum depletion of our oil fields.

Authors: Chiatti Giancarlo , Chiavola Ornella , Palmieri Fulvio , Pompei Roberto 
Published: May 2018

Background:The paper deals with a diesel common rail nozzle in which a novel orifice layout is implemented.Objective:Its influence on the nozzle mechanical-hydraulic behavior and on the spray shape transient development is experimentally investigated.Methods:In the research, a solenoid injector for light duty diesel engines is equipped with the novel nozzle prototype and tested. The prototype layout is described, pointing out the features of the nozzle orifices, in which a Slot cross-section is adopted; the investigation is accomplished extending the hydraulic tests and the spray visualizations to a reference nozzle with standard holes. The influence of the hole layout on the mechanical-hydraulic behavior of the nozzle is assessed by experimental analysis based on the rate of injection measurement, in comparison with the reference nozzle. Once the hydraulic behavior of the novel nozzle has been characterized in terms of mass flow rate, the slot influence on the spray shape is assessed analyzing the macroscopic features such as the penetration distance and the spray angle, in non evaporative conditions. The study is carried out under transient injection conditions, for different injection pressures, up to 1400 bar.Results:The results on spray characteristics also provide reference information to set up spray models suited to take the Slot orifice into account.

Published: May 2018

In this present study, a protocol was developed for the DNA profiling of medicinally important Rauwolfia species (05 species) by ISSR-PCR method. Initially genomic DNA was isolated from the fresh leaves (1 gram) of 24 months old Rauwolfia tetraphylla, R.serpentina, R.pentaphylla, R.vomitaria and R.micrantha. The content of genomic DNA isolated from 1 gram of fresh leaves of these five species ranges from 1.6 to 3.4 µg. Out of six inter simple sequence repeats (ISSR) primers used, HY3 primer has given the good amplification with distinct bands which were reproducible. The range of DNA bands produced by the HY3 primer were between 300 bp to 1500 bp among the five species. A dendrogram was constructed on the basis of similarity matrix data by unweighted pair group method with arithmetic average (UPGMA) cluster analysis using indigenous software. Average genetic similarity generated by HY3 has revealed 38% similarity between species of Sub cluster-A and species of Sub cluster-B which is consistent with their geographical distribution i.e. Sub cluster-A species R.tetraphylla and R.serpentina inhabit peninsular India, Sub cluster- B species R.micrantha and R. vomitoria inhabit the Himalayan foot hills. The developed protocol of DNA profiling in Rauwolfia species by ISSR-PCR method could be used efficiently for the differentiation and identification of the Rauwolfia species at molecular level.

Published: May 2018

ABSTRACT
This case report demonstrates the treatment of a skeletal Class II high-angle adult patient with bimaxillary protrusion, angle Class I occlusion, and crowded anterior teeth. A ribbon-wise arch wire and a customized lingual appliance with anterior vertical slots were used to achieve proper torque control of the maxillary anterior teeth. An orthodontic anchor screw and a palatal bar were used for vertical control to avoid increasing the Frankfort-mandibular plane angle (FMA) by maxillary molar extrusion. Through the combined use of the ribbon-wise customized lingual appliance, palatal bar, and orthodontic anchor screw, vertical control and an excellent treatment result were achieved without the vertical and horizontal bowing effects peculiar to conventional lingual treatment.
Dialektika Agama dan Budaya dalam "Berkah" Nawu Sendang Selirang
Authors: Ghafur Waryono Abdul 
Published: May 2018

This article discusses Sendang Selirang, a local culture in Kotagede, Yogyakarta, the existence of which is conserved to the present time. There is a tradition to clean the pool located in the former Mataram kingdom in Kota Gede. This tradition has different meaning among the three different groups of people: abangan, santri, and the intellectuals. This article starts from Clifford Geertz’s interpretative ethnography to understand cultural events existing in the society. This research found that among abangan community, Sendang Selirang is a ritual and ceremony which is performed with religious emotion and considered to be mystical. This meaning is different from that the group of santri, represented by Muhammadiyah. For some Muhammadiyah activists, this tradition is a part of superstition, bid’ah, and kurafat, so that it should be avoided. Meanwhile, for the intellectuals, it is not enough to view this tradition only from religious perspective. It should also be viewed from cultural perspective. This view functions as mediation for the other two groups of community that potentially arise conflicts. This research also found that the different views among the communities are influenced not only by the religious factor, but also other factors, such as equality in handling the ceremony and material benefit. However, the unity in diversity should be highlighted to create harmony among them. Artikel ini membahas tentang Sendang Selirang sebagai salah satu budaya lokal khas di Kotagede Yogyakarta yang sampai sekarang masih dilestarikan. Ada tradisi membersihkan kolam yang berada di bekas lingkungan Kerajaan Mataram awal di Kotagede. Tradisi tersebut dimaknai secara berbeda oleh tiga kelompok di Kotagede: abangan, santri, dan intelektual. Tulisan ini berangkat dari kerangka yang dibangun oleh Clifford Geertz dengan etnografi interpretatifnya untuk memahami suatu peristiwa budaya yang terjadi di masyarakat. Hasil penelitian ini menun jukkan bahwa bagi masyarakat abangan, Sendang Selirang menjadi ritus dan upacara yang dilaksanakan dengan emosi keagamaan dan mempunyai sifat keramat. Pemaknaan tersebut ternyata berbeda bagi kelompok santri yang direpresentasikan dengan Muhammadiyah. Bagi beberapa aktivis Muhammadiyah, tradisi nawu sendang (Sendang Selirang) merupakan bagian dari tahayul, bid’ah, dan kurafat sehingga harus dihindari. Sementara bagi kelompok “cendekiawan”, peristiwa nawu sendang tidak cukup dipandang dari sisi agama, namun juga dari sisi budaya. Ini sebagai “jalan tengah” untuk menengahi dua kelompok sebelumnya yang berpotensi konflik. Temuan di lapangan menunjukkan bahwa perbedaan pandangan dari tiga kelompok tersebut dipengaruhi oleh bukan semata pandangan keagamaan masing-masing, tapi juga oleh faktor lain di luar agama, seperti pemerataan dalam penyelenggaraan dan keuntungan material. Kebersamaan dalam perbedaan tetap yang diutamakan, sehingga harmoni terus berjalan dengan baik.
