Published: April 2019

Background:
The search for potential markers for a timely and accurate diagnosis of periprosthetic joint infection (PJI) is ongoing. Previous studies have focused on inflammatory markers and have rarely examined coagulation-related indicators. The purpose of this study was to evaluate the values of plasma fibrinogen, D-dimer, and other blood markers for the diagnosis of PJI through a multicenter retrospective study.

Methods:
A total of 565 revision total hip and knee arthroplasty cases were enrolled in this study from January 2016 through December 2017, 126 of which had coagulation-related comorbidities and were analyzed separately. The remaining 439 cases included 76 PJI and 363 non-PJI patients. The definition of PJI was based on the International Consensus Meeting (ICM) on Periprosthetic Infection criteria. The diagnostic values of D-dimer, plasma fibrinogen, the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, and white blood-cell (WBC) count were analyzed using receiver operating characteristic (ROC) curves.

Results:
ROC curves showed that plasma fibrinogen had the highest area under the curve (AUC), 0.852, followed by 2 classical markers, the CRP level and ESR, which had an AUC of 0.810 and 0.808, respectively. D-dimer had an AUC of 0.657, which was the second lowest value and only slightly higher than that of the WBC count, 0.590. The optimal threshold for plasma D-dimer was 1.25 μg/mL, with a sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 0.645, 0.650, 0.278, and 0.897, respectively. The optimal threshold for plasma fibrinogen was 4.01 g/L, which showed good sensitivity, specificity, PPV, and NPV, with values of 0.763, 0.862, 0.537, and 0.946, respectively.

Conclusions:
Plasma D-dimer may have a very limited diagnostic value for PJI, while plasma fibrinogen, another coagulation-related indicator, exhibits promising performance. Plasma fibrinogen has good sensitivity and specificity for diagnosing PJI, with values similar to those of classical markers, including CRP level and ESR.

Postoperative Mobilization After Superior Rotator Cuff Repair: Sling Versus No Sling
Authors: Tirefort Jérôme , Schwitzguebel Adrien J. , Collin Philippe , Nowak Alexandra , Plomb-Holmes Chantal , Lädermann Alexandre 
Published: April 2019

Background:
Patients are commonly advised to wear a sling for 4 to 6 weeks after rotator cuff repair despite negative effects of early immobilization and benefits of motion rehabilitation. The aim of this study was to compare clinical and radiographic outcomes up to 6 months following rotator cuff repair with and without postoperative sling immobilization.

Methods:
We randomized 80 patients scheduled for arthroscopic repair of a small or medium superior rotator cuff tear into sling and no-sling groups (40 patients each). Passive mobilization was performed in both groups during the first 4 postoperative weeks, and this was followed by progressive active mobilization. Patients were evaluated clinically at 10 days and 1.5, 3, and 6 months and using ultrasound at 6 months. Univariable and multivariable analyses were performed to determine if postoperative scores were associated with sex, age at surgery, immobilization, arm dominance, a biceps procedure, resection of the distal part of the clavicle, or preoperative scores.

Results:
The sling and no-sling groups had similar preoperative patient characteristics, function, and adjuvant procedures. At 10 days, there was no difference in pain between the 2 groups (mean pain score [and standard deviation], 5.2 ± 2.3 versus 5.2 ± 1.9, p = 0.996). In comparison with the sling group, the no-sling group showed greater mean external rotation (23.5° ± 15.6° versus 15.3° ± 14.6°, p = 0.017) and active elevation (110.9° ± 31.9° versus 97.0° ± 25.0°, p = 0.038) at 1.5 months as well as better mean active elevation (139.0° ± 24.7° versus 125.8° ± 24.4°, p = 0.015) and internal rotation (T12 or above in 50% versus 28%, p = 0.011) at 3 months. Ultrasound evaluation revealed no significant differences at 6 months in tendon thickness anteriorly (p = 0.472) or posteriorly (p = 0.639), bursitis (p = 1.000), echogenicity (p = 0.422), or repair integrity (p = 0.902). Multivariable analyses confirmed that the mean American Shoulder and Elbow Surgeons (ASES) score increased with patient age (beta, 0.60; p = 0.009), the Single Assessment Numeric Evaluation (SANE) decreased with sling immobilization (beta, −6.33; p = 0.014), and pain increased with sling immobilization (beta, 0.77; p = 0.022).

Conclusions:
No immobilization after rotator cuff repair is associated with better early mobility and functional scores in comparison with sling immobilization. Postoperative immobilization with a sling may therefore not be required for patients treated for a small or medium tendon tear.

Authors: Goltz Daniel E. , Ryan Sean P. , Hopkins Thomas J. , Howell Claire B. , Attarian David E. , Bolognesi Michael P. , Seyler Thorsten M. 
Published: April 2019

Background:
A reliable prediction tool for 90-day adverse events not only would provide patients with valuable estimates of their individual risk perioperatively, but would also give health-care systems a method to enable them to anticipate and potentially mitigate postoperative complications. Predictive accuracy, however, has been challenging to achieve. We hypothesized that a broad range of patient and procedure characteristics could adequately predict 90-day readmission after total joint arthroplasty (TJA).

Methods:
The electronic medical records on 10,155 primary unilateral total hip (4,585, 45%) and knee (5,570, 55%) arthroplasties performed at a single institution from June 2013 to January 2018 were retrospectively reviewed. In addition to 90-day readmission status, >50 candidate predictor variables were extracted from these records with use of structured query language (SQL). These variables included a wide variety of preoperative demographic/social factors, intraoperative metrics, postoperative laboratory results, and the 30 standardized Elixhauser comorbidity variables. The patient cohort was randomly divided into derivation (80%) and validation (20%) cohorts, and backward stepwise elimination identified important factors for subsequent inclusion in a multivariable logistic regression model.

Results:
Overall, subsequent 90-day readmission was recorded for 503 cases (5.0%), and parameter selection identified 17 variables for inclusion in a multivariable logistic regression model on the basis of their predictive ability. These included 5 preoperative parameters (American Society of Anesthesiologists [ASA] score, age, operatively treated joint, insurance type, and smoking status), duration of surgery, 2 postoperative laboratory results (hemoglobin and blood-urea-nitrogen [BUN] level), and 9 Elixhauser comorbidities. The regression model demonstrated adequate predictive discrimination for 90-day readmission after TJA (area under the curve [AUC]: 0.7047) and was incorporated into static and dynamic nomograms for interactive visualization of patient risk in a clinical or administrative setting.

Conclusions:
A novel risk calculator incorporating a broad range of patient factors adequately predicts the likelihood of 90-day readmission following TJA. Identifying at-risk patients will allow providers to anticipate adverse outcomes and modulate postoperative care accordingly prior to discharge.

Main Hakim Sendiri (Eigen Richting) dalam Terjadinya Pencurian Sapi di Madura
Authors: Wartiningsih Wartiningsih 
Published: April 2019

Maraknya tindakan main hakim di beberapa daerah mencerminkan ketidakpercayaan masyarakat terhadap kinerja kepolisian dan sistem peradilan pidana di Indonenesia. Demikian juga di Madura masyarakat menghakimi pencuri yang mencoba atau mencuri sapi. Nampaknya telah terjadi perubahan paradigma dalam masyarakat, yang dahulu menjunjung nilai-nilai kemanusiaan. Respon masyarakat di luar pelaku main hakim sendiri menujukkan kepuasannya jika pelaku pencurian dihakimi massa. Penelitian ini akan menganalisis tindakan main hakim sendiri dari 2 aspek yaitu, aspek masyarakat akan dianalisis dengan teori sistem hukum dari Lawrence M. Friedman. Sedangkan dari kepolisian akan dianalisis dari aspek kelembagaan berdasarkan teori Chambliss and Saidman.Jenis penelitian ini adalah penelitian yuridis sosiologis dengan pendekatan fakta. Data dan informasi yang diperoleh dianalisis secara kualitatif untuk menemukan fakta (fact-finding), yang kemudian menuju pada identifikasi (problem-identification) dan pada akhirnya menuju kepada penyelesaian masalah (problem-solution). Berdasarkan hasil dan pembahasan, rekomendasi yang diberikan oleh peneliti adalah perlu penyuluhan dan penyadaran dari masyarakat bahwa tindakan main hakim sendiri adalah perbuatan yang melawan hukum. Untuk kepolisian perlu ada konsolidari dan komitmen yang tinggi untuk bisa melakukan penegakan hukum karena non-enfocerment atau pembiaran tidak dapat dibenarkan dari aspek teori maupun aspek praktik yang melanggar hak tersangka dan merupakan hambatan bagi tersangka dalam upaya memperoleh keadilan.

This paper is based on research using the main approach of normative juridical (Legal Research) and juridical Empirical as supporting Normative approach. The result of research is the concept of Restorative Justice has been effectively implemented by law enforcers despite many shortcomings but does not reduce the implementation in the interest of the Child in the against of law. Assistance of ABH Cases must be accompanied by Family, Lawyers, BAPAS (Balai Permasyarakatan), NGOs and community leaders. Companions to ABH are not the only cases that Restorative Justice can implement but all cases involving children as child offenders. ABH mentoring started from the investigation stage until the completion of the crime that should be ABH accountable and returned ABH to the community to socialize. Therefore, it is hoped that the decision of law enforcers concerning the future of ABH is more to be considered for the future to become a better person.

Sour Gas Production: Moving from Conventional to Advanced Environmentally Friendly Schemes
Authors: Lallemand F. , Rocher A. , Aimard N. 
Published: April 2019

Abstract
For decades to come, gas will be the energy source of choice to meet increasing demand. Oil and gas operators, who have already developed those fields the easiest and the cheapest to produce, will have to develop fields with much higher acid gas content in the future, as forty per cent of the remaining (natural or associated) gas reserves are sour, totaling over 350 Tcf with over 10% H2S, and almost 700 Tcf with over 10% CO2, with both these components present most of the time.
Future sour gas sustainable developments will have to deal with three major challenges: additional costs associated to the production and separation of large quantities of acid gases, more ambitious objectives to reduce green house gases emissions, and global and durable saturation of the sulfur market. This leads to the development of more energy efficient technologies for acid gas separation and more generally to new gas production schemes.
Acid gas cycling for Enhanced Oil Recovery or acid gas disposal by reinjection offers a promising alternative to avoid costly sulfur production and reduce CO2 emissions to the atmosphere when producing these large very sour gas reserves. However, acid gas injection requires the qualification of a suitable and well known geological formation and there are some drawbacks and constraints related to the surface facilities that will be discussed in the paper.
The paper also presents the necessary evolutions of the production / treatment technologies, and the new solutions under development or already developed and proven by Total and its partners, to cope with these new environment and constraints. They include environmentally friendly methods to store sulfur, as well as energy efficient processes to separate acid gases from sour gas, such as the cryogenic separation process well adapted to acid gas injection schemes, and new solvent processes for enhanced sweetening performances.
Surfactant Prefloods During Carbon Dioxide Foam Injection for Integrated Enhanced Oil Recovery in Fractured Oil-Wet Carbonates

Summary
An integrated enhanced-oil-recovery (EOR) (IEOR) approach is used in fractured oil-wet carbonate core plugs where surfactant prefloods reduce interfacial tension (IFT), alter wettability, and establish conditions for capillary continuity to improve tertiary carbon dioxide (CO2) foam injections. Surfactant prefloods can alter the wettability of oil-wet fractures toward neutral/weakly-water-wet conditions that in turn reduce the capillary threshold pressure for foam generation in matrix and create capillary contact between matrix blocks. The capillary connectivity can transmit differential pressure across fractures and increase both mobility control and viscous displacement during CO2-foam injections. Outcrop core plugs were aged to reflect conditions of an ongoing CO2-foam injection field pilot in west Texas. Surfactants were screened for their ability to change the wetting state from oil-wet using the Darcy-scale Amott-Harvey index. A cationic surfactant was the most effective in shifting wettability from an Amott-Harvey index of –0.56 to 0.09. Second waterfloods after surfactant treatments and before tertiary CO2-foam injections recovered an additional 4 to 11% of original oil in place (OIP) (OOIP), verifying the favorable effects of a surfactant preflood to mobilize oil. Tertiary CO2-foam injections revealed the significance of a critical oil-saturation value below which CO2 and surfactant solution were able to enter the oil-wet matrix and generate foam for EOR. The results reveal that a surfactant preflood can reverse the wettability of oil-wet fracture surfaces, lower IFT, and lower capillary threshold pressure to reduce oil saturation to less than a critical value to generate stable CO2 foam.
Field Validation of a New Bottomhole-Assembly Model for Unconventional Shale Plays
Authors: Wilson J. K. 
Published: April 2019

Summary
A new drillstring model has been developed that determines the static and dynamic behavior of bottomhole assemblies (BHAs) in 3D wellbores. An attempt at validating this model with field data is presented, and it shows a close agreement between observed and calculated downhole BHA behavior.
Validation tests were conducted using high-frequency downhole data measured within a motor-assisted rotary-steerable BHA. The gathered data were used to verify the calculated mechanical loads, predicted lateral natural frequencies of the BHA, estimated directional performance of the downhole assembly, and the torsional resonance resulting from high-frequency torsional oscillations (HFTOs).
Results from the field tests show a strong correlation between measured and calculated bending-moment values, as well as lateral natural frequencies of the BHA, with an average of 3% error across all data sets. The primary source of error is thought to be borehole spiraling, which is quantified through analysis of the downhole bending-moment data. In addition, the model is shown to provide close estimates of the actual directional performance of both steerable mud motors and rotary-steerable BHAs. However, the directional-calculation vs. -measurement comparison does reveal a need to incorporate a rate-of-penetration (ROP) dependency within the directional-prediction algorithms.
Produced-Fluid Composition Redistribution in Source Rocks for Hydrocarbon-In-Place and Thermodynamic Recovery Calculations
Authors: Baek Seunghwan , Yucel Akkutlu I.. 
Published: April 2019

Summary
Source rocks, such as organic-rich shale, consist of a multiscale pore structure that includes pores with sizes down to the nanoscale, contributing to the storage of hydrocarbons. In this study, we observed hydrocarbons in the source rock partition into fluids with significantly varying physical properties across the nanopore-size distribution of the organic matter. This partitioning is a consequence of the multicomponent hydrocarbon mixture stored in the nanopores, exhibiting a significant compositional variation by pore size—the smaller the pore size, the heavier and more viscous the hydrocarbon mixture becomes. The concept of composition redistribution of the produced fluids uses an equilibrium molecular simulation that considers organic matter to be a graphite membrane in contact with a microcrack that holds bulk-phase produced fluid.
A new equation of state (EOS) was proposed to predict the density of the redistributed fluid mixtures in nanopores under the initial reservoir conditions. A new volumetric method was presented to ensure the density variability across the measured pore-size distribution to improve the accuracy of predicting hydrocarbons in place. The approach allowed us to account for the bulk hydrocarbon fluids and the fluids under confinement.
Multicomponent fluids with redistributed compositions are capillary condensed in nanopores at the lower end of the pore-size distribution of the matrix (&lt;10 nm). The nanoconfinement effects are responsible for the condensation. During production and pressure depletion, the remaining hydrocarbons become progressively heavier. Hence, hydrocarbon vaporization and desorption develop at extremely low pressures. Consequently, hydrocarbon recovery from these small pores is characteristically low.
Solitary Fibrofolliculoma of the Upper Eyelid in a 68-year Old Female: A Case Report
Authors: Wang Wenqiu , Cheng Jinwei 
Published: April 2019

Abstract
Background

Fibrofolliculoma is a benign, perifollicular, connective tissue tumor, which is a clinically asymptomatic, 2-4 mm, skin-colored, dome-shaped smooth papule. It usually arises in the form of multiple lesions, and very rarely presents as a solitary lesion.

Case presentation

A 68-year-old female presented with an asymptomatic, flesh-colored mass on the right upper eyelid. The 5×5×4 mm lesion was located near upper lid margin. It was a skin-colored, dome-shaped, smooth nodule, with eyelashes on the surface, rubbery to palpation and not painful. The lesion was excised completely, and the diagnosis of fibrofolliculoma was confirmed through a histological exam.

Conclusions

Solitary fibrofolliculomas is rarely arising in the eyelid. However, it should be suspected when a localized mass lesion of the eyelid is encountered.
Possibility of using dabigatran in patients with atrial fibrillation and acute coronary syndrome and PCI
Authors: Erlich A. D. 
Published: April 2019

This article is devoted to the problem of combined antithrombotic therapy in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) due to acute coronary syndrome (ACS). Traditionally, these patients require an oral anticoagulant (OAC) to prevent stroke and dual anti-platelet therapy (DAT) to prevent coronary complications. The necessity of combining various antithrombotic drugs, since this greatly increases the risk of bleeding is becoming an increasing relevant clinical problem. The prolonged triple therapy in the form of a combination of OAC and DAT does not bring additional benefit to the patients, but, on the contrary, may be potentially dangerous. Currently, the possibility of using several new oral anticoagulants (NOAC) in patients with AF and ACS/PCI in the form of dual therapy has been proven: combination of OAC and p2Y12 inhibitor. The article focuses on the RE-DUAL PCI study, in which the use of dabigatran at both doses permitted in AF (150 mg twice daily and 110 mg twice daily) in combination with the p2Y12 inhibitor was associated with fewer bleeding complications than during the triple therapy in the form of OAK + DAT.The article presents a clinical case of the possibility of management of a patient with AF and ACS under the modern clinical guidelines, as well as an overview of current guidelines for the use of OAC and DAT in patients with AF undergoing PCI.
