Maternal-fetal prognosis of obstetric emergencies at the maternity ward of the Mamou regional hospital
Background: Pregnant women may be at risk of unpredictable obstetric complications such as: bleeding, dystocia, acute fetal suffering, pre-eclampsia and eclampsia. This maternal-fetal prognosis of obstetric emergencies is influenced by factors that are most often related to complications that alter the course or outcome of a pregnancy and require prompt care. The objectives of this study are to analyze the factors that influence the maternal-fetal prognosis of obstetric emergencies; determine their frequency, describe the clinical profiles of patients and evaluate the maternal-fetal prognosis.Methods: The study was conducted at the Mamou Regional Hospital. It was a 6-month quantitative, descriptive and analytical study, from July 1st to December 31st, 2016, including all parturient women whose term is greater than or equal to 28 weeks of amenorrhoea.Results: The study covered 377 obstetric emergencies out of a total of 1273 deliveries, or 29.61%. Factors influencing the prognosis were: young age, parity, unfavorable socio-economic conditions and difficult baseline conditions. The main obstetric emergencies recorded were acute fetal suffering, disproportion and narrowed pelvis. The dominant mode of delivery was caesarean section with a frequency of 89.65%. Maternal lethality is 3.44% and fetal lethality is 5.14%.Conclusions: Obstetric emergency is a frequent situation where better management would improve the prognosis of the mother and fetus
Holographic Entanglement Entropy at Finite Temperature
Using a holographic proposal for the entanglement entropy we study its
behavior in various supergravity backgrounds. We are particularly interested in
the possibility of using the entanglement entropy as way to detect transitions
induced by the presence horizons. We consider several geometries with horizons:
the black hole in , nonextremal Dp-branes, dyonic black holes
asymptotically to and also Schwarzschild black holes in global
coordinates. Generically, we find that the entanglement entropy does not
exhibit a transition, that is, one of the two possible configurations always
dominates.Comment: v3: 31 pp, ten figures, modified to match version accepted by IJMP
Lâepilepsie en milieu scolaire : enquete chez les enseignants de la ville de Kati au Mali et revue de la litterature
Introduction La prĂ©valence de lâĂ©pilepsie en Afrique subsaharienne est Ă©levĂ©e. Nous avons menĂ© une Ă©tude transversale et descriptive dans lâensemble des Ă©coles primaires de la ville de Kati (200 000 habitants). Les enseignants furent interviewĂ©s de maniĂšre exhaustive Ă lâaide de questionnaires portant, dâune part, sur les connaissances, attitudes et pratiques des enseignants en matiĂšre dâĂ©pilepsie et, dâautre part, sur leurs avis sur les consĂ©quences psychologiques, sociales pour lâenfant Ă©pileptique et les incidences sur sa scolaritĂ©.RĂ©sultats Nous avons interrogĂ© 92 enseignants (60 hommes et 32 femmes). LâĂąge moyen des enseignants Ă©tait de 30 ans. La majoritĂ© dâentre eux avait une expĂ©rience professionnelle de plus de 5 ans. Environ 38% des enseignants attribuaient la maladie Ă une cause surnaturelle. Plus de 39% des enseignants pensaient que lâĂ©pilepsie Ă©tait contagieuse et 61% pensaient que lâĂ©pilepsie Ă©tait incurable. 79% interdisaient systĂ©matiquement la pratique du sport Ă lâenfant Ă©pileptique. Environ 55% pensaient que lâenfant Ă©pileptique avait des capacitĂ©s cognitives infĂ©rieures Ă celles de lâenfant non Ă©pileptique et 88% affirmaient que lâenfant épileptique Ă©tait incapable dâavoir une scolaritĂ© normale. 59% trouvaient que lâĂ©lĂšve Ă©pileptique Ă©tait victime de stigmatisation et de marginalisation. Devant une crise, 68% renvoyaient lâenfant au domicile.Conclusion Ce travail fait apparaĂźtre un besoin de formation des enseignants en matiĂšre dâĂ©pilepsie. Les donnĂ©es actuelles sur la frĂ©quence de lâĂ©pilepsie en milieu scolaire justifient une attention particuliĂšre des services de santĂ© et de ceux de lâĂ©ducation nationale sur la scolarisation de lâenfant Ă©pileptique.Mots clĂ©s : Epilepsie, Ecole, Enseignants, Mali, Pratiques
Entanglement Entropy from a Holographic Viewpoint
The entanglement entropy has been historically studied by many authors in
order to obtain quantum mechanical interpretations of the gravitational
entropy. The discovery of AdS/CFT correspondence leads to the idea of
holographic entanglement entropy, which is a clear solution to this important
problem in gravity. In this article, we would like to give a quick survey of
recent progresses on the holographic entanglement entropy. We focus on its
gravitational aspects, so that it is comprehensible to those who are familiar
with general relativity and basics of quantum field theory.Comment: Latex, 30 pages, invited review for Classical and Quantum Gravity,

Dipole Coupling Effect of Holographic Fermion in the Background of Charged Gauss-Bonnet AdS Black Hole
We investigate the holographic fermions in the charged Gauss-Bonnet
black hole background with the dipole coupling between fermion and gauge field
in the bulk. We show that in addition to the strength of the dipole coupling,
the spacetime dimension and the higher curvature correction in the gravity
background also influence the onset of the Fermi gap and the gap distance. We
find that the higher curvature effect modifies the fermion spectral density and
influences the value of the Fermi momentum for the appearance of the Fermi
surface. There are richer physics in the boundary fermion system due to the
modification in the bulk gravity.Comment: 16 pages, accepted for publication in JHE
Absence of a Fermi surface in classical minimal four-dimensional gauged supergravity
We demonstrate that the two point function of the supercurrent dual to the
gravitino in the four-dimensional extremal anti-de Sitter Reissner-Nordstrom
black hole does not exhibit a Fermi surface singularity. In our analysis, we
utilize the ingoing Eddington-Finkelstein coordinate system, which enables us
to bypass certain complications in the determination of the allowed near
horizon behavior of the gravitino field at zero frequency. We check that our
method agrees with previous results for the massless charged Dirac field.Comment: 12 pages, 1 figur
