Authors: Kruse Ethan , Agol Eric , Luger Rodrigo , Foreman-Mackey Daniel 
Published: September 2019

Abstract
We implement a search for exoplanets in campaigns zero through eight (C0–8) of the K2 extension of the Kepler spacecraft. We apply a modified version of the QATS planet search algorithm to K2 light curves produced by the EVEREST pipeline, carrying out the C0–8 search on 1.5 × 105 target stars with magnitudes in the range of Kp = 9−15. We detect 818 transiting planet candidates, of which 374 were undiscovered by prior searches, with {64, 15, 5, 2, 1} in {2, 3, 4, 5, 6}-planet multiplanet candidate systems, respectively. Of the new planets detected, 100 orbit M dwarfs, including one that is potentially rocky and in the habitable zone. A total of 154 of our candidates reciprocally transit with our solar system: they are geometrically aligned to see at least one solar system planet transit. We find candidates that display transit timing variations and dozens of candidates on both period extremes with single transits or ultrashort periods. We point to evidence that our candidates display similar patterns in frequency and size–period relation to confirmed planets, such as tentative evidence for the radius gap. Confirmation of these planet candidates with follow-up studies will increase the number of K2 planets by up to 50%, and characterization of their host stars will improve statistical studies of planet properties. Our sample includes many planets orbiting bright stars amenable for radial velocity follow-up and future characterization with JWST. We also list the 579 eclipsing binary systems detected as part of this search.

Abstract
Recent advances in black hole astrophysics, particularly the first visual evidence of a supermassive black hole at the center of the galaxy M87 by the Event Horizon Telescope, and the detection of an orbiting “hot spot” nearby the event horizon of Sgr A* in the Galactic center by the Gravity Collaboration, require the development of novel numerical methods to understand the underlying plasma microphysics. Non-thermal emission related to such hot spots is conjectured to originate from plasmoids that form due to magnetic reconnection in thin current layers in the innermost accretion zone. Resistivity plays a crucial role in current sheet formation, magnetic reconnection, and plasmoid growth in black hole accretion disks and jets. We included resistivity in the three-dimensional general-relativistic magnetohydrodynamics (GRMHD) code BHAC and present the implementation of an implicit–explicit scheme to treat the stiff resistive source terms of the GRMHD equations. The algorithm is tested in combination with adaptive mesh refinement to resolve the resistive scales and a constrained transport method to keep the magnetic field solenoidal. Several novel methods for primitive-variable recovery, a key part in relativistic magnetohydrodynamics codes, are presented and compared for accuracy, robustness, and efficiency. We propose a new inversion strategy that allows for resistive-GRMHD simulations of low gas-to-magnetic pressure ratio and highly magnetized regimes as applicable for black hole accretion disks, jets, and neutron-star magnetospheres. We apply the new scheme to study the effect of resistivity on accreting black holes, accounting for dissipative effects as reconnection.
Mettre en œuvre des actions de formation et de changement : une relecture contemporaine de Kurt Lewin dans le contexte de l’agroécologie
Authors: Faulx Daniel , Nion Cybill , Collière Pierre , Capoen Eric 
Published: September 2019

Kurt Lewin a marqué l’histoire des sciences sociales et s’est penché plus particulièrement sur les questions de l’apprentissage, du changement et des groupes. Dans cet article, nous abordons de quelle manière ses théories, ses concepts et ses pratiques peuvent nourrir les formateurs actuels. En effet, les questions posées par Lewin restent d’actualité : Comment former ? Comment soutenir l’apprentissage ? Comment gérer les différentes dimensions d’une innovation sociale ou technique ? L’approche Lewinienne sera appliquée ici aux actions d’une organisation non gouvernementale conduisant des projets orientés vers des pratiques agricoles plus respectueuses de l’homme et de l’environnement. Dans le cadre d’un partenariat entre cette organisation et un service universitaire, nous verrons quelle conceptualisation des pratiques et quelles propositions peuvent résulter du croisement de l’expérience de terrain et des théories de Lewin, le tout au service de la formation aujourd’hui.
« Regarde dans quel état nous nous mettons ! » Luttes contre les violences sexuelles et renouveau du féminisme en Argentine
Authors: Carbajal Mariana , Ichaso Inès , Sandoval Maritza 
Published: September 2019

Les luttes contre la violence machiste en Argentine se sont répandues et popularisées depuis 2015. Loin d’être une injonction des classes moyennes, la prise de conscience féministe et les revendications pour les droits des femmes traversent toute la société : professionnelles, paysannes, ouvrières, étudiantes, adolescentes, majeures, filles, mères et grands-mères. Pour éclairer ces luttes, Inès Ichaso s’entretient avec la journaliste argentine Mariana Carbajal qui a contribué à impulser le mouvement « Ni Una Menos » (« Pas une de moins »). Mariana Carbajal fait partie des Journalistes d’Argentine en Réseau pour une Communication non Sexiste (PAR, de son sigle en espagnol). Elle collabore au journal progressiste Página 12 et anime des émissions sur le genre et le féminisme à la radio et à la télévision. Elle a notamment publié les ouvrages Je te crois, sœur (2019), Maltraitées. Violence de genre dans les rapports de couple (2014) et L’avortement en débat.

Athlètes, Atlas et baccalauréat parental
Authors: Miano Éric 
Published: September 2019

Nous sommes à une époque où la question de l’intérêt, des droits et des potentielles capacités de nos enfants est centrale. Leurs devenirs, et les nécessaires compétences de ceux qui vont devoir en garantir le respect et le développement sont étudiés de toutes parts et font l’objet de bien des débats. Faut-il désormais faire passer un baccalauréat option Compétences parentales suffisamment bonnes pour être autorisé à devenir parent ? Que demandons-nous à travers cette idée de maîtrise de compétence dont nous parlons si souvent ? Réussir l’éducation parfaite pour l’enfant parfait ? Nous verrons que non seulement les questions d’éducation et de parentalité ne peuvent être réduites à une simple affaire de compétence que l’on aurait ou non, mais aussi qu’il y a là, dans l’intérêt de nos enfants, quelque chose à penser de ce besoin constant de vouloir ainsi leur demander de devenir des êtres formidables, capables de porter le poids du monde et de nos faiblesses sur leurs compétentes épaules.
Simultaneous Implantation of Refractive Lenticule and Intracorneal Ring Segment in the Management of Pellucid Marginal Degeneration
Authors: Kalinnikov Yury , Leontyeva Galina , Zinovyeva Alexandra , Nevrov Denis 
Published: September 2019

PURPOSE:
To describe a patient with pellucid macular degeneration suffering from visual deterioration due to high irregular astigmatism and intolerant to contact lenses, who underwent a new surgical procedure that combined intrastromal lamellar keratoplasty and a 359° intracorneal ring segment implantation, enabling both ametropia and corneal thinning correction.

METHODS:
Case report.

RESULTS:
Refractive lenticule obtained during a myopic small incision lenticule extraction procedure was used as the donor lamellar graft. The technique described allowed for partial cylinder reduction and reinforcement of the thinned cornea. Uncorrected distance visual acuity improved from 0.02 to 0.5 (decimal) and corrected distance visual acuity improved from 0.4 to 0.7 with a decrease of 4.50 diopters in corneal astigmatism.

CONCLUSIONS:
Despite the lack of long-term observation, the new technique described in this case report was successful for this specific patient and therefore might be effective and safe in severe stages of disease.

Published: September 2019

Background: Catheter-related blood stream infection (CRBSI) contributes to morbidity and mortality among patients on haemodialysis (HD). We carried out a systematic review and meta-analysis to assess the efficacy of antimicrobial lock solutions (ALS) in preventing CRBSI.Method: Electronic search of randomised controlled trials (RCTs) comparing ALS with other agents was performed up to January 2013. DerSimonian and Laird meta-analysis was performed to obtain pooled relative risk (RR) from which efficacy of ALS and numbers needed to treat (NNT) were calculated. In a restricted analysis, pooled RRs where compared using a test of interaction to calculate ratio of relative risks (RRR). Meta-regression analysis was employed to explore sources of heterogeneity.Results: Sixteen RCTs involving 2016 individuals met the inclusion criteria. The efficacy of ALS in preventing CRBSI was 80% with NNT of 3 patients to prevent one CRBSI. The RR of CRBSI was significantly lower with ALS compared with heparin-only lock solution [RR {95% confidence interval (CI)} = 0.20 (0.13-0.31)]. With low dose (≤ 5 mg/ml) and high dose (40 mg/ ml) gentamicin-containing ALS, the RR (95% CI) of developing CRBSI was 0.03 (0.01-0.13) and 0.18 (0.03-0.98), respectively, with no significant difference [RRR (95% CI) = 0.2 (0.02-1.61), p = 0.126]. Heterogeneity was explained by a statistically significant association between rate of CRBSI and catheter days (p = 0.037). Conclusion: ALS are effective in preventing CRBSI. Low dose gentamicin should be preferred over high dose gentamicin as an ALS because it offers similar benefit in preventing CRBSI with lesser risk of toxicity from systemic leakage and subsequent development of drug resistance.
An HIV-positive status and short term perioperative mortality – a systematic review
Authors: Moodley Yoshan , Govender Kumeren 
Published: September 2019

Background: A contemporary summary describing the impact of an HIV-positive status on short term perioperative mortality is lacking.Objective: To collate and summarise published data related to short term perioperative mortality from studies comparing HIVpositive and HIV-negative patient groups.Method: We conducted a systematic review of the published literature by performing structured searches of two medical literature databases. Pre-defined inclusion/exclusion criteria were used to identify potentially relevant manuscripts. Further screening of the reference lists of eligible manuscripts, as well as a prior systematic review was also performed to identify any additional manuscripts that may have been relevant. Data retrieved from eligible manuscripts included, amongst other variables: study and population descriptions, surgical category (cardiac or noncardiac surgery), as well the incidence of short term perioperative mortality. Crude odds ratios were calculated for each eligible manuscript to describe the association between HIV status and short term perioperative mortality.Results: Our systematic review consisted of 12 manuscripts describing 12 studies. The majority of manuscripts described studies conducted in countries with a low burden of HIV infection. Most manuscripts described findings from a noncardiac surgery setting. Crude associations between an HIV-positive status and a higher odds of short term perioperative mortality were noted for data from 2 of the 12 manuscripts, while the association was unclear in the remaining 10 manuscripts. Conclusion: Evidence supporting a higher odds of short term perioperative mortality in patients with an HIV-positive status is unconvincing. Further research is required to adequately investigate this.
Lateral Wall Decompression for Malunited Calcaneal Fractures
Authors: Agarwala Sanjay , Sobti Anshul Shyam 
Published: September 2019

ABSTRACT

Aim
The purpose of this case series is to reintroduce Kashiwagi decompression as a viable treatment option for malunited calcaneal fractures, delineate the operative technique, and discuss its advantages.

Materials and methods
From August 2004 to May 2013, 18 patients with Sanders type I malunited calcaneal fractures with lateral heel pain and impingement were treated with the lateral wall decompression technique. The functional outcome was assessed using the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale.

Results
Eleven patients were males and seven were females, with an average age of 48.4 years. Ten patients had left feet fracture and eight had right feet fracture. Among all the 18 patients with a ‘poor’ score at baseline, 2 (11.11%) scored ‘excellent’, 11 (61.11%) scored ‘good’ and 3 (16.67%) scored ‘fair’ during postoperative evaluation. The average time to return to daily activities was 10.2 weeks (8–12.5 weeks).

Conclusion
Lateral wall osteotomy and decompression effectively addresses the pathology in cases of lateral abutment due to a malunited calcaneal fracture. This technique has advantages of ensuring a reliable resolution with good clinical outcomes and produces fewer postoperative complications.

Clinical significance
Malunion is a common complication with calcaneal fracture. It affects normal function. In malunited calcaneal fractures, the lateral wall of the calcaneum forms a lateral wall exostosis that causes both subfibular impingement and peroneal tendinopathy or displacement. There is need for a viable treatment option for malunions with lateral wall exostosis after calcaneal fractures. This study describes a surgical technique as a solution for the above.

Proximal Medial Tibial Bone Graft Harvesting in Foot and Ankle Surgery
Authors: Rachha Rajesh , Sugathan Hari Kovilazhikathu , Dalal Rakesh 
Published: September 2019

ABSTRACT
Cancellous bone graft harvesting from proximal tibia is usually by a lateral approach. We describe our technique and results in harvesting proximal tibia bone graft by a medial approach in foot and ankle surgery. Our results confirm that medial proximal tibial bone graft harvesting is a relatively safe and easy procedure to obtain adequate amount of autogenous cancellous bone graft. Donor site morbidity was found to be very low and fusion rate was found to be excellent in a variety of foot and ankle surgeries.

Minimally Invasive Management of Fracture Calcaneum
Authors: Prabhakar Sharad , Gahlot Nitesh , Satish Bhava RJ 
Published: September 2019

ABSTRACT
Modern usage of minimally invasive methods has been applied to fractures of the calcaneus with good effect in the 21st century. The Essex-Lopresti maneuver has been modified, distraction devices are being judicially used, and the advent of image intensifiers and small joint arthroscopes have allowed accurate visualization of the reduced fracture as well as joint surfaces. It is important to understand that the three-dimensional (3D) anatomy, Böhler and Gissane angles, and heel height have to be restored. The surgeon should be ready to convert to an open procedure at any time. We describe here the method we use in our institute, and this is one of the many methods of managing this complex injury.

Irreducible Dislocation of Great Toe Interphalangeal Joint by an Accessory Sesamoid Bone: A Case Report and Review of Literature
Authors: Rajasekaran S , Silvampatti Sundararajan 
Published: September 2019

ABSTRACT
Irreducible dislocation of interphalangeal joint is a rare condition with only a few case reports in literature. Here, we report a case with irreducible dislocation of interphalangeal joint due to sesamoid bone interposition, which required open reduction. A 45-year-old male had a fall from height with irreducible dislocation of interphalangeal joint of great toe. Intraoperatively, the interposition of sesamoid bone over the dorsal aspect of proximal phalanx was identified. Displaced volar plate with sesamoid bone was reduced into the position, and the joint was stabilized with k wire. On follow-up, we observed that the patient had no discomfort or pain for 6 months. The displacement of sesamoid bone with volar plate and intact collateral ligaments locks the joint in extension and obstructs the reduction of interphalangeal joint dislocation. One should have the suspicion of possibility of open reduction after observing the interposition of sesamoid bone over the dorsal aspect of the proximal phalanx. Dorsal approach is usually advocated; medial approach can be used if there is wound over the plantar aspect.

Stress Fracture of the Fibular Sesamoid Bone of the Foot in Cricket: An Unusual Injury in Bowlers
Authors: Prabhakar Sharad , Dhillon Himmat , Dhillon Sidak , Behera Prateek 
Published: September 2019

ABSTRACT
An unusual case of fibular sesamoid stress fracture in the back foot of a bowler is presented. The diagnosis was delayed due to the lack of awareness of the support medical staff of the cricketer. Special radiological views and computed tomographic scans confirmed the diagnosis; nonoperative measures cured the pain, but this recurred on subsequent bowling activities. The current player gave up the game, but the literature supports operative intervention in cases that fail conservative regimens. This case is presented to highlight the occurrence of this rare injury in fast bowlers, and we recommend careful examination of the foot when it is the trailing foot, because this has significant forefoot dorsiflexion during the stance phase.

Use of Cellular and Tissue-based Product in the Treatment of Diabetic Foot Ulcers
Authors: Serena Thomas E , Yaakov Raphael A , Mostow Eliot N 
Published: September 2019

ABSTRACT

Introduction
The prevalence of diabetes has been rising sharply and the rise in chronic wounds parallels this trend. Lower extremity ulcers present a serious complication for people with diabetes. While debridement of necrotic tissue and off-loading plays an important role in wound healing, many patients with diabetic foot ulcers (DFUs) fail to heal with standard of care (SOC) alone. Unresolved ulcers can lead to complications, such as osteomyelitis and amputation. There continues to be a need for the evaluation of novel wound therapies that can accelerate wound healing and lower the cost of care associated with DFUs. This paper presents recent evidence for the use of cellular and/or tissue-based products (CTPs) and offers an approach for selecting an appropriate CTP.

Materials and methods
A systematic literature search was conducted using PubMed, Embase, Medline, Cochrane library, and NHS Economic Evaluation Database. Full-length articles in English were assessed for relevance to select studies on effectiveness and economic evaluations. Additionally, Google Scholar was used to gather relevant literature on commonly used CTPs, including Apligraf®, EpiFix®, and Dermagraft®.

Findings
Results from randomized controlled trials (RCTs) provided evidence for the superior efficacy of CTPs over SOC alone in treatment of chronic DFUs. In recent studies evaluating commonly used CTPs, significantly higher number of DFUs achieved complete closure with EpiFix® when compared to either Apligraf® or Dermagraft®. While cost-effectiveness studies continue to be limited, current literature suggests that CTPs can decrease the long-term costs associated with the care of DFUs by increasing the healing rate, reducing recovery time, and lowering the risk of infection and complications. Cellular and/or tissue-based products (CTPs) may result in higher average number of ulcer-free months and lower average number of amputations or resections compared to SOC alone.

Midfoot Charcot Arthropathy: Overview and Surgical Management
Authors: Rajasekaran S , Silvampatti Sundararajan , Nagaraja HS 
Published: September 2019

ABSTRACTMidfoot Charcot arthropathy is a progressive deforming condition characterized by recurrent ulceration leading to high morbidity and amputation with lack of timely intervention. Nonoperative treatment is largely reserved for acute phase disease. Recent trend in management is early surgical interventions which could alter deforming forces and prevent deformity progression, as well as surgeries which provide osseously stable plantigrade foot. However, there are no clear-cut evidencebased guidelines regarding timing of interventions and method of techniques in surgical stabilization. This study discusses about surgical technique in the management of midfoot Charcot.How to cite this articleSilvampatti S, Nagaraja HS, Rajasekaran S.

Lower Limb Refractory Ulcers and Postoperative Nonhealing Wound: Review of the Literature
Authors: Jha Shiva S 
Published: September 2019

ABSTRACT
Lower limb ulcers including nonhealing postoperative wounds are challenging problems, especially to orthopedic surgeons. Such ulcers are recognized complications of rheumatoid arthritis but the scenario has changed for the better since the advent of aggressive disease-modifying antirheumatic drugs (DMARDs). Out of different types of lower limb ulcerations including venous, arterial, lymphatic, malignancies, infection, medication induced and inflammatory, autoimmune inflammatory conditions need to be delineated. They can be improved, though slowly with DMARDs. The pathogenesis is multifactorial but most prevalent are vasculitis. The various investigative tools for diagnosing the causes of these ulcers include plethysmography, ultrasound, angiography, computed tomography, magnetic resonance imaging, chromosomal analysis, and, most importantly, skin biopsy. Clinical presentation of the patient still remains the supreme disease tracker. Review of the literature is presented to ascertain the evidence for best clinical practice.
