Evaluation of Large-scale Data to Detect Irregularity in Payment for Medical Services
Authors: Park Junghyun , Yoon Seokjoon , Kim Minki 
Published: April 2016

SummaryBackground: Sophisticated anti-fraud systems for the healthcare sector have been built based on several statistical methods. Although existing methods have been developed to detect fraud in the healthcare sector, these algorithms consume considerable time and cost, and lack a theoretical basis to handle large-scale data.Objectives: Based on mathematical theory, this study proposes a new approach to using Benford’s Law in that we closely examined the individual-level data to identify specific fees for in-depth analysis.Methods: We extended the mathematical theory to demonstrate the manner in which large-scale data conform to Benford’s Law. Then, we empirically tested its applicability using actual large-scale healthcare data from Korea’s Health Insurance Review and Assessment (HIRA) National Patient Sample (NPS). For Benford’s Law, we considered the mean absolute deviation (MAD) formula to test the large-scale data.Results: We conducted our study on 32 diseases, comprising 25 representative diseases and 7 DRG-regulated diseases. We performed an empirical test on 25 diseases, showing the applicability of Benford’s Law to large-scale data in the healthcare industry. For the seven DRG-regulated diseases, we examined the individual-level data to identify specific fees to carry out an in-depth analysis. Among the eight categories of medical costs, we considered the strength of certain irregularities based on the details of each DRG-regulated disease.Conclusions: Using the degree of abnormality, we propose priority action to be taken by government health departments and private insurance institutions to bring unnecessary medical expenses under control. However, when we detect deviations from Benford’s Law, relatively high contamination ratios are required at conventional significance levels.
Data Driven Computer Simulation to Analyse an ECG Limb Lead System Used in Connected Health Environments
Authors: Finlay Dewar , Guldenring Daniel , Breen Cathal , Bond Raymond 
Published: April 2016

SummaryBackground: Recently under the Connected Health initiative, researchers and small-medium engineering companies have developed Electrocardiogram (ECG) monitoring devices that incorporate non-standard limb electrode positions, which we have named the Central Einthoven (CE) configuration.Objectives: The main objective of this study is to compare ECG signals recorded from the CE configuration with those recorded from the recommended Mason-Likar (ML) configuration.Methods: This study involved extracting two different sets of ECG limb leads from each patient to compare the difference in the signals. This was done using computer simulation that is driven by body surface potential maps. This simulator was developed to facilitate this experiment but it can also be used to test similar hypotheses. This study included, (a) 176 ECGs derived using the ML electrode positions and (b) the 176 corresponding ECGs derived using the CE electrode positions. The signals from these ECGs were compared using root mean square error (RMSE), Pearson product-moment correlation coefficient (r) and similarity coefficient (SC). We also investigated whether the CE configuration influences the calculated mean cardiac axis. The top 10 cases where the ECGs were significantly different between the two configurations were visually compared by an ECG interpreter.Results: We found that the leads aVL, III and aVF are most affected when using the CE configuration. The absolute mean difference between the QRS axes from both configurations was 28° (SD = 37°). In addition, we found that in 82% of the QRS axes calculated from the CE configuration was more rightward in comparison to the QRS axes derived from the ML configuration. Also, we found that there is an 18% chance that a misleading axis will be located in the inferior right quadrant when using the CE approach. Thus, the CE configuration can emulate right axis deviation. The clinician visually identified 6 out of 10 cases where the CE based ECG yielded clinical differences that could result in false positives.Conclusions: The CE configuration will not yield the same diagnostic accuracy for diagnosing pathologies that rely on current amplitude criteria. Conversely, rhythm lead II was not significantly affected, which supports the use of the CE approach for assessing cardiac rhythm only. Any computerised analysis of the CE based ECG will need to take these findings into consideration.
SDSS-II SUPERNOVA SURVEY: AN ANALYSIS OF THE LARGEST SAMPLE OF TYPE IA SUPERNOVAE AND CORRELATIONS WITH HOST-GALAXY SPECTRAL PROPERTIES

Published: April 2016

ABSTRACT
Using the largest single-survey sample of Type Ia supernovae (SNe Ia) to date, we study the relationship between properties of SNe Ia and those of their host galaxies, focusing primarily on correlations with Hubble residuals (HRs). Our sample consists of 345 photometrically classified or spectroscopically confirmed SNe Ia discovered as part of the SDSS-II Supernova Survey (SDSS-SNS). This analysis utilizes host-galaxy spectroscopy obtained during the SDSS-I/II spectroscopic survey and from an ancillary program on the SDSS-III Baryon Oscillation Spectroscopic Survey that obtained spectra for nearly all host galaxies of SDSS-II SN candidates. In addition, we use photometric host-galaxy properties from the SDSS-SNS data release such as host stellar mass and star formation rate. We confirm the well-known relation between HR and host-galaxy mass and find a 3.6σ significance of a nonzero linear slope. We also recover correlations between HR and host-galaxy gas-phase metallicity and specific star formation rate as they are reported in the literature. With our large data set, we examine correlations between HR and multiple host-galaxy properties simultaneously and find no evidence of a significant correlation. We also independently analyze our spectroscopically confirmed and photometrically classified SNe Ia and comment on the significance of similar combined data sets for future surveys.
CLASH: JOINT ANALYSIS OF STRONG-LENSING, WEAK-LENSING SHEAR, AND MAGNIFICATION DATA FOR 20 GALAXY CLUSTERS*

selected from Cluster Lensing And Supernova survey with Hubble (CLASH). Our analysis combines constraints from 16-band Hubble Space Telescope observations and wide-field multi-color imaging taken primarily with Suprime-Cam on the Subaru Telescope, spanning a wide range of cluster radii (10″–16′). We reconstruct surface mass density profiles of individual clusters from a joint analysis of the full lensing constraints, and determine masses and concentrations for all of the clusters. We find the internal consistency of the ensemble mass calibration to be ≤5% ± 6% in the one-halo regime (200–2000 kpc h
−1) compared to the CLASH weak-lensing-only measurements of Umetsu et al. For the X-ray-selected subsample of 16 clusters, we examine the concentration–mass (c–M) relation and its intrinsic scatter using a Bayesian regression approach. Our model yields a mean concentration of

, which is in excellent agreement with Λ cold dark matter predictions when the CLASH selection function based on X-ray morphological regularity and the projection effects are taken into account. We also derive an ensemble-averaged surface mass density profile for the X-ray-selected subsample by stacking their individual profiles. The stacked lensing signal is detected at 33σ significance over the entire radial range ≤4000 kpc h
−1, accounting for the effects of intrinsic profile variations and uncorrelated large-scale structure along the line of sight. The stacked mass profile is well described by a family of density profiles predicted for cuspy dark-matter-dominated halos in gravitational equilibrium, namely, the Navarro–Frenk–White (NFW), Einasto, and DARKexp models, whereas the single power-law, cored isothermal and Burkert density profiles are disfavored by the data. We show that cuspy halo models that include the large-scale two-halo term provide improved agreement with the data. For the NFW halo model, we measure a mean concentration of

THERMAL PRESSURES IN THE INTERSTELLAR MEDIUM OF THE MAGELLANIC CLOUDS*
Authors: Welty Daniel E. , Lauroesch James T. , Wong Tony , York Donald G. 
Published: April 2016

ABSTRACT
We discuss the thermal pressures (n
H
T) in predominantly cold, neutral interstellar gas in the Magellanic Clouds, derived from analyses of the fine-structure excitation of neutral carbon, as seen in high-resolution Hubble Space Telescope/Space Telescope Imaging Spectrograph spectra of seven diverse sight lines in the LMC and SMC. Detailed fits to the line profiles of the absorption from C i, C i*, and C i** yield consistent column densities for the three to six C i multiplets detected in each sight line. In the LMC and SMC, N(C i
tot) is consistent with Galactic trends versus N(Na i) and N(CH), but is slightly lower versus N(K i) and N(H2). As for N(Na i) and N(K i), N(C i
tot) is generally significantly lower, for a given N(Htot), in the LMC and (especially) in the SMC, compared to the local Galactic relationship. For the LMC and SMC components with well-determined column densities for C i, C i*, and C i**, the derived thermal pressures are typically factors of a few higher than the values found for most cold, neutral clouds in the Galactic ISM. Such differences are consistent with the predictions of models for clouds in systems (like the LMC and SMC) that are characterized by lower metallicities, lower dust-to-gas ratios, and enhanced radiation fields—where higher pressures are required for stable cold, neutral clouds. The pressures may be further enhanced by energetic activity (e.g., due to stellar winds, star formation, and/or supernova remnants) in several of the regions probed by these sight lines. Comparisons are made with the C i observed in some quasar absorption-line systems.

ABSTRACT
We present clustering analysis results from 10,381 Lyman break galaxies (LBGs) at z ∼ 4–7, identified in the Hubble legacy deep imaging and new complimentary large-area Subaru/Hyper Suprime-Cam data. We measure the angular correlation functions of these LBGs at z ∼ 4, 5, 6, and 7 and fit these measurements using halo occupation distribution (HOD) models that provide an estimate of halo masses,

WISEA J114724.10-204021.3: A FREE-FLOATING PLANETARY MASS MEMBER OF THE TW HYA ASSOCIATION
Authors: Schneider Adam C. , Windsor James , Cushing Michael C. , Kirkpatrick J. Davy , Wright Edward L. 
Published: April 2016

ABSTRACT
We present WISEA J114724.10-204021.3, a young, low-mass, high-probability member of the TW Hya association (TWA). WISEA J114724.10-204021.3 was discovered based on its red AllWISE color (W1 − W2 = 0.63 mag) and extremely red 2MASS J − K
S color (>2.64 mag), the latter of which is confirmed with near-infrared photometry from the Visible and Infrared Survey Telescope for Astronomy Hemisphere Survey (J − K
S = 2.57 ± 0.03). Follow-up near-infrared spectroscopy shows a spectral type of L7 ± 1 as well as several spectroscopic indicators of youth. These include a peaked H-band shape and a steeper K-band slope, traits typically attributed to low surface gravity. The sky position, proper motion, and distance estimates of WISEA J114724.10-204021.3 are all consistent with membership in the ∼10 Myr old TWA. Using the age of the TWA and evolutionary models, we estimate the mass of WISEA J114724.10-204021.3 to be 5–13 M
Jup, making it one of the youngest and lowest-mass free-floating objects yet discovered in the Solar neighborhood.
Repenser l’éthique avec Paul Ricœur
Authors: Svandra Philippe 
Published: April 2016

L’objet de cet article est moins de faire l’éloge de Paul Ricœur que de montrer qu’il existe un véritable usage pratique, et même opérationnel de cette pensée, et particulièrement dans le champ de la médecine et du soin. D’autant plus que l’auteur de « Soi-même comme un autre » occupe une place importante dans le paysage philosophique contemporain que ce soit dans le champ de la phénoménologie que dans celui de l’herméneutique. C’est en faisant appel à ces deux traditions philosophiques que Ricœur propose une éthique narrative particulièrement féconde pour la réflexion soignante. Toutefois, dans cet article, nous nous arrêterons plus particulièrement au philosophe qui nous invite à habiter et à agir dans le monde, celui qui propose, à partir de la tradition aristotélicienne et kantienne, une éthique pratique. Nous verrons ainsi de quelle manière les trois moments de « sa petite éthique - visée de la vie bonne, avec et pour les autres, dans des institutions justes » peuvent éclairer la réflexion éthique et politique des acteurs du soin.

Published: April 2016

Introduction : dans le contexte de la mondialisation et de l’internationalisation de la formation universitaire, plusieurs programmes offrent la possibilité à leurs étudiants d’inclure un stage international dans leur formation initiale. La montée de ce phénomène est omniprésente dans les universités canadiennes, ce qui entraîne une mobilité étudiante accrue vers l’international et un nombre croissant de stages effectués à l’étranger. But : cette étude exploratoire vise à mieux comprendre les processus de transfert et d’appropriation des savoirs lors d’un stage international et interculturel d’étudiantes en sciences infirmières dans des milieux de soins africains. Cadre : les modèles de l’empowerment et du Cycle des connaissances à la pratique ont guidé cette recherche. Méthode : une étude de cas multiples a été conduite auprès de six milieux de soins provenant de deux pays d’Afrique francophone. Des entrevues individuelles ont été réalisées auprès des étudiantes québécoises (n=11) et des infirmiers africains (n=9), et des entrevues de groupe auprès des partenaires (n=2). De l’observation directe et participante a également eu lieu lors des séjours en milieux de soins africains des onze étudiantes et de deux chercheuses. Résultats : des avantages de cette stratégie d’apprentissage ont été notés, notamment sur les plans personnel et professionnel des étudiantes infirmières ainsi que sur le transfert des connaissances aux milieux d’accueil. Discussion : quatre thématiques découlant de la discussion des résultats ont fait l’objet de recommandations, soit l’importance : 1) de la communication bidirectionnelle, de la continuité entre les stagiaires et du soutien à distance et sur place, 2) de renforcer le savoir sociopolitique émancipatoire, 3) de diversifier les milieux et les expositions à des pratiques locales et populaires, et 4) des différentes phases du Cycle des connaissances à la pratique.
La réforme régionale en France : une occasion manquée ?
Authors: Bonnet-Pineau Élisabeth 
Published: April 2016

À chaque année sa réforme : en 2014, la nouvelle carte administrative française ramène de 22 à 13 le nombre des régions. L’émergence de la région devenue une collectivité territoriale de plein exercice fut lente et consacrée seulement en 1982. Depuis quelques années, plusieurs rapports ont proposé la réduction du nombre des régions et une redéfinition des compétences des conseils départementaux et régionaux.L’objet principal de la réforme visait à « doter les régions d’une taille critique » pour leur permettre d’ « exercer les compétences stratégiques qui leur sont attribuées et de réaliser des gains d’efficience ».Or la région n’est toujours pas consacrée comme chef de file et les conseils départementaux sont plus que jamais inscrits dans le paysage institutionnel aux côtés des intercommunalités de plus en plus larges. L’objectif d’économies ne pourra être obtenu que par le renforcement de ces intercommunalités, tant les dotations du gouvernement aux collectivités ont été rabotées. Et si les fusions ont été privilégiées, l’effet de taille est loin d’avoir été appliqué. La réforme paraît être une occasion manquée …
Maternal Obesity and Congenital Anomalies: Its Implications and Future Trends
Authors: Madhab Gayatri , Bharadwaz Arindam 
Published: April 2016

ABSTRACT

Objectives
To find the current body of evidence for maternal obesity's association with and its burden on congenital malformations and to estimate its financial and mortality implications as well as future trend.

Materials and methods
Thorough search and review of current literature with deductive interpretations.

Results and evidence
Obesity is associated with certain types of congenital anomalies like neural tube defects (NTD), congenital heart defects (CHDs), orofacial defects, etc. The burden in absolute numbers for major CHD and NTD attributable to obesity can be estimated to be 0.42 to 1.05 and 0.588 to 1.12 per 10,000 births respectively.

Remarks and conclusion
Contribution of maternal obesity on perinatal mortality could be anywhere from 6 to 20 per 1,00,000 births. However, its economic implications could be substantial. Current trend indicates that contribution of obesity to certain congenital anomalies may increase in future.

ABSTRACTCesarean scar pregnancy (CSP) is the rarest type of ectopic pregnancy implanted in the myometrium at the site of the previous cesarean section scar. It may lead catastrophic complications like uterine rupture and uncontrollable hemorrhage.4 Early diagnosis can offer treatment options of avoiding uterine rupture and hemorrhage, thus, preserving the uterus and future fertility.The conservative treatment can be by local and/or systemic administration of methotrexate, dilatation and curettage, excision of trophoblastic tissues (laparoscopy/laparotomy), bilateral internal artery ligation with trophoblastic evacuation and uterine artery embolization7 combined with curettage and/ or methotrexate. We did successful treatment of a viable CSP by systemic injections of methotrexate followed by selective uterine artery embolization in combination with dilatation and curettage.How to cite this articleMehta P, Vishwanath U, Joseph S, Anitha M.

Assessment of the Efficacy of Different Methods of Second Trimester Abortion: An Initial Experience in Eastern Nepal
Authors: Chhetri Shailaja , Pokharel Hanoon , Rijal Rohit , Lama Sushma 
Published: April 2016

ABSTRACT

Background
Abortions performed in the second trimester account for a disproportionate amount of abortion-related morbidity and mortality.

Materials and methods
To assess the effectiveness of medical vs the surgical methods for second trimester abortions.

Results
A total number of 141 patients were included in the study from September 2009 till August 2012 who underwent second trimester abortion. A total number of 75 patients underwent medical abortion and 66 patients underwent surgical dilatation and evacuation (D&E). Surgical treatment with D&E was more effective and safer than medical treatment for second trimester abortion, The overall complications were seen more in the medically treated cohort with 20 vs 6% in the surgical cohort (p = 0.02), with higher incidence of incomplete abortion (13 vs 0) and a higher amount of blood loss (129.4 ± 20.6 ml vs 69.6 ± 11.4 ml, p < 0.001) requiring transfusion.

Conclusion
This study demonstrates that the surgical method of second trimester abortion is more effective and safe procedure in experienced centers and as compared to medical methods. The complication rates are lower and it also is more cost-effective as it can be performed in an outpatient setting and does not require hospital admission.

Twin Pregnancy Discordant for Anencephaly with Severe Polyhydramnios
Authors: Najam Rehana 
Published: April 2016

ABSTRACT
Twin pregnancy is a high-risk pregnancy with many complications. Anencephaly is one anomaly which is commoner in twins than in singleton pregnancy. Dizygotic as well as monozygotic twins discordant for structural anomaly requires an individual approach regarding pregnancy complications. The major issue with these pregnancies require early diagnosis and management options, especially if diagnosed early. Selective fetocide is a management option in at least dizygotic twins.
