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

Risk communication and community engagement in COVID-19: Fighting infodemics among non-governmental/community-based organizations in Africa

As the world battles the latest strain of the coronavirus known as COVID-19 characterized as a pandemic by the World Health Organization (WHO), “infodemics” – an excessive amount of (mostly untrue) information about the pandemic that makes it difficult to discern essential information – has been identified by the health body as one of the major obstacles to be tackled to win the war against the raging pandemic. In a bid to control spread of the virus, the WHO published a guideline on Risk Communication and Community Engagement (RCCE) to COVID-19, noting these responses are vital for containment. The COVID-19 pandemic is testing and stretching health systems and their ability to effectively communicate with their populations. Failure to communicate accurate public health facts could lead to losses of trust, reputation, economy, and lives. This paper turns its searchlight on nongovernmental and community-based organizations (NGOs and CBOs) in Africa, and how they handle infodemics in an information environment battling not just a health pandemic, but a hoax pandemic too. Methods: The study employed mixed method, with data drawn from Africanbased NGOs and CBOs via online questionnaire and interviews against the backdrop of the Situational Theory of Publics. Findings reveal, based on what NGO/CBO survey respondents report their local clients think, that many at the grassroots still do not believe COVID-19 is real, while others view it as government’s scheme to embezzle funds. NGO/CBOs therefore look to WHO and Health Ministries for accurate information. It concludes that RCCE with the public and atrisk populations help reduce confusion and builds trust in the public health guidance community members can take thereby restricting the disease spread as an outcome of the RCCE approach

Beyond LLM in M-theory

The Lin, Lunin, Maldacena (LLM) ansatz in D = 11 supports two independent Killing directions when a general Killing spinor ansatz is considered. Here we show that these directions always commute, identify when the Killing spinors are charged, and show that both their inner product and resulting geometry are governed by two fundamental constants. In particular, setting one constant to zero leads to AdS7 x S4, setting the other to zero gives AdS4 x S7, while flat spacetime is recovered when both these constants are zero. Furthermore, when the constants are equal, the spacetime is either LLM, or it corresponds to the Kowalski-Glikman solution where the constants are simply the mass parameter.Comment: 1+30 pages, footnote adde

Four-Dimensional SCFTs from M5-Branes

We engineer a large new set of four-dimensional N=1 superconformal field theories by wrapping M5-branes on complex curves. We present new supersymmetric AdS_5 M-theory backgrounds which describe these fixed points at large N, and then directly construct the dual four-dimensional CFTs for a certain subset of these solutions. Additionally, we provide a direct check of the central charges of these theories by using the M5-brane anomaly polynomial. This is a companion paper which elaborates upon results reported in arXiv:1112:5487.Comment: 45 pages, 11 figure

Fermions and Type IIB Supergravity On Squashed Sasaki-Einstein Manifolds

We discuss the dimensional reduction of fermionic modes in a recently found class of consistent truncations of type IIB supergravity compactified on squashed five-dimensional Sasaki-Einstein manifolds. We derive the lower dimensional equations of motion and effective action, and comment on the supersymmetry of the resulting theory, which is consistent with N=4 gauged supergravity in $d=5$, coupled to two vector multiplets. We compute fermion masses by linearizing around two $AdS_{5}$ vacua of the theory: one that breaks N=4 down to N=2 spontaneously, and a second one which preserves no supersymmetries. The truncations under consideration are noteworthy in that they retain massive modes which are charged under a U(1) subgroup of the $R$-symmetry, a feature that makes them interesting for applications to condensed matter phenomena via gauge/gravity duality. In this light, as an application of our general results we exhibit the coupling of the fermions to the type IIB holographic superconductor, and find a consistent further truncation of the fermion sector that retains a single spin-1/2 mode.Comment: 43 pages, 2 figures, PDFLaTeX; v2: added references, typos corrected, minor change

Disordered Systems and the Replica Method in AdS/CFT

We formulate a holographic description of effects of disorder in conformal field theories based on the replica method and the AdS/CFT correspondence. Starting with $n$ copies of conformal field theories, randomness with a gaussian distribution is described by a deformation of double trace operators. After computing physical quantities, we take the $n \to 0$ limit at the final step. We compute correlation functions in the disordered systems by using the holographic replica method as well as the formulation in the conformal field theory. We find examples where disorder changes drastically the scaling of two point functions. The renormalization group flow of the effective central charge in our disordered systems is also discussed.Comment: 26 pages, references added, published versio
