Introduction: Infections represent a real public health problem aggravating the morbidity and mortality of hospitalized patients. Methods: This was a retrospective study with descriptive purposes over a period of 05 years, in the Pneumology Department of the University Hospital of Cocody. Results: The average age in our population was 42 years. We observed a male predo- minance of 64.5%, with a sex ratio of 1.8. Medical history was dominated by HIV infection (23.5%), followed by tuberculosis (15.6%). Concerning lifestyle, smoking was found in 38% of cases. Symptoms progressed chronically in 80% of cases. An infectious syndrome was found in 75% of cases. Microbial culture was positive in 42% of cases. Pseudomonas aeruginosa and Klebsiella pneumoniae were encountered in 26.4% of cases each, followed by Echerichia coli in 10.4% of cases. Klebsiella pneumoniae in the first three years topped the list, but gradually. Pseudomonas aeruginosa maintained its leadership over the last three years. Pseudomonas aeruginosa isolates expressed a resistance rate of 9.8% to ceftazidime and 8.1% to imipenem;to aztreonam (36%), ticarcillin (33.3%) and levofloxacin. These strains were susceptible to fosfomycin (100%), mero- penem (96.6%) and amikacin (96%). For isolated strains of Entero- bacteria- ceae, resistance was observed about ticarcillin (83.3%) and amoxicillin clavula- nic acid (71.2%). Streptococcaceae showed resistance to tetracycline (69.2%) and erythromycin (50%). Over the years there has been an increase in re- sistance to amoxicillin-clavulanic acid ceftriaxone. The death rate was 14%. Conclusion: The bacterial profile of infections is dominated by germs respon- sible for nosocomial infection with significant mortality.

Background: Human African trypanosomiasis (HAT) occurs in three historical foci in the Central African Republic. Objective: To describe the morbi-mortality of childhood HAT in rural Central African Republic with the aim of early management. Methods: Descriptive and analytic cross-sectional study conducted from January 1, 2017 to March 30, 2018 at Nola prefectural hospital. This study was included all children seen as outpatients and/or hospitalized in the pediatric wards, in whom the diagnosis of HAT was confirmed. Statistical analysis was performed using Epi-info software. Results: Forty children were included from Bilolo (60%), Nola (30%) and Salo (10%). The sex ratio was 0.66 with a median age of 8.65 ± 12.48 years. Fever (82.5%), nocturnal insomnia (75%), daytime somnolence (67.5%), headache (65%), polyarthralgia (62.5%), convulsions 52.5% (n = 21), tremor (27.5%), trypanidism (7.5%) and delirium (2.5%) were the main functional signs. Examination signs were adenopathy (52.5%), paresthesia (30%), decreased cutaneous-abdominal reflexes (25%) and osteoarticular reflexes (17.5%), hyperesthesia (20%), extrapyramidal hypertonia (15%) and depression (2.5%). The children were in the lymphatic-blood phase in 65% of cases, and meningoencephalitis in 35%. Pentamidine was administered in 65% of cases. Four children died and 6 had neurological sequelae. There was an association between age under 5, Bilolo’s focus, the children’s history and the severity of the disease. Age under 5, gender, household, children’s activity, history and occurrence of sequelae were also associated. Conclusion: HAT remains a permanent threat to Central African children. Any clinical presentation combining long-term infectious signs and unexplained neurological or neuropsychological disorders must be treated with caution.

Background: The World Health Organization (WHO) has set a goal to eradicate or at least significantly reduce the prevalence the human immunodeficiency virus (HIV), hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) by 2030. The main objective was to provide an evolving overview of the prevalence of HIV, HBV and HCV infection between 2003 and 2022 in Burkina Faso. Methods: It was a retrospective cross-sectional study based on data from 2003 to 2022. The data were collected using information available in the databases of the HOSCO and CERBA laboratories and included all individuals who underwent HIV and/or HBV and/or HCV testing. Data analysis was performed using SPSS version 20.0, EpiInfo 7, and R version 4.1.0. Results were considered statistically significant if p Results: The study recorded 7432 samples and the mean age of the subjects was 27.98 ± 8.50 years. During this period, the respective prevalence of HIV, HBV, and HCV were 4.66% (346/7432), 8.77% (582/6636) and 5.54% (322/5816). However, from 2003 to 2022, there was a significant decrease (P y=−1.75x+12.59;y=−0.24x+10.01and y=−0.11x+6.02, with “y” corresponding to prevalence and “x” to the years. Conclusion: Burkina Faso needs to rigorously apply prevention and control strategies recommended by the WHO by 2030.

Gestational trophoblastic disease is an abnormal proliferation of trophoblastic tissue during pregnancy. It occurs in women of childbearing age, although a few cases have also been observed in post-menopausal women, although it is extremely rare in the latter. Here we describe a rare case of complete hydatidiform mole in a 56-year-old female patient who presented with genital bleeding combined with nausea and vomiting and a gravid uterus 16 cm in height. The ultrasound findings and the increase in serum β-HCG to 182566.00 mIU/ml suggested a diagnosis of complete hydatidiform mole. Given the post-menopausal state and the future risk of post-molar gestational trophoblastic neoplasia, we opted for total hysterectomy without preservation of the adnexa via a transabdominal approach, followed by antimitotic treatment with methotrexate. The uterus measured 18.45 cm × 11.18 cm with intra cavitary vesicles. Microscopic examination showed chorionic villi of variable size and shape, most of which were dilated and oedematous, associated with trophoblastic cell proliferation and haemorrhage suggestive of complete benign hydatidiform mole. Follow-up showed a consistent decrease in serum β-HCG levels and no evidence of residual disease. A suspicion of gestational trophoblastic disease should be borne in mind when evaluating a patient with peri- or post-menopausal bleeding to avoid delay in diagnosis and treatment.

In the present paper, we consider elliptic equations with nonlinear and nonlao mogeneous Robin boundary conditions of the type {-div（B（x,u）△u） = f in Ω,u=0 on Гo, B（x,u）Vu·n^-＋γ（x）h（u） = 9 on Г1,where f and g are the element of L^1（Ω） and L^1（Г1）, respectively. We define a notion of renormalized solution and we prove the existence of a solution. Under additionM assumptions on the matrix field B we show that the renormalized solution is unique.

In this article,we set out to reconcile a general conceptualization of disaster temporalities by drawing on the epitome example of a creeping disaster,namely *** argument is driven by the recognition that slowly manifesting disaster impacts pose distinct challenges for decision makers and researchers while there is a tendency for the disaster literature to overlook the role of disaster onset *** specifically and as a starting point,we identify four key themes that merit particular attention when dealing with creeping disasters:(1)our understanding of disaster as a phenomenon;(2)measurement and operationalization;(3)early warning and response;and(4)disaster management and *** integrating conceptual discussions of disaster with famine scholarship—a phenomenon often excluded from mainstream disaster research—this article provides fresh perspectives on disaster science as well as a number of implications for how we think about disaster risk reduction.

Dynamic Simulations of Post-stall Performance in Multistage Axial Compressors

Journal of Thermal Science 2012年第4期21卷 311-321页

In this contribution a quasi-one-dimensional tool for stationary and transient simulations of post-stall flows in multistage axial compressors is presented. An adapted version of the 1D Euler equations with additional source terms is discretized with a finite volume method and solved in time by a fourth-order Runge-Kutta scheme. The equations are discretized at midspan both inside the blade rows and the non-bladed regions. The source terms express the blade-flow interactions and are estimated by calculating the velocity triangles for each blade row. Loss and deviation correlations are implemented and compared to experimental data in normal flow, stalled flow and reversed flow regions. Transient simulations are carried out and a parameter study is presented to analyze the shape of the surge cycles and the frequency of the surge oscillations. At last, a bleeding control strategy is implemented to study the recoverability of the instabilities in a compression system.

The aim of this paper is to test a developed SOR R＆B method using the Chebyshev accelerator algorithm to solve the Laplace equation in a cubic 3D configuration. Comparisons are made in terms of precision and computing time with other elliptic equation solvers proposed in the open source LIS library. The first results, obtained by using a single core on a HPC, show that the developed SOR R＆B method is efficient when the spectral radius needed for the Chebyshev acceleration is carefully pre-estimated. Preliminary results obtained with a parallelized code using the MPI library are also discussed when the calculation is distributed over one hundred cores.
