Introduction: In Benin, the maternal mortality rate remains high and one of the main causes is preeclampsia in its complicated forms, including eclampsia. For this, treatment is most often provided in an intensive care unit by a multidisciplinary team involving obstetricians and intensive care doctors. Objective: To determine the prognostic factors of eclamptics treated in intensive care units in two university teaching hospitals in Cotonou. Patients and Method: The study was transversal descriptive and analytical with prospective collection of data from May 1 to July 31, 2022, in the intensive care units of CHU-MEL and CNHU-HKM in Cotonou. The sampling was non-probability with exhaustive recruitment of all cases of eclampsia managed in hospital intensive care units. Clinical, therapeutic and evolutionary data were studied. Data analysis was done with Epi info 7.***.1.0 software. Results: Fifty-five eclamptics were included. The incidence was 12.39%. The average age of eclamptics was 24.67 ± 1.41 years, with a reference rate of 85.45%. Primigravidae represented 52.73%. A history of eclampsia and/or high blood pressure (14.54%) was associated with mortality. Cesarean section was indicated in 85.45% and general anesthesia, was the technique used in 95.75% of cases. Eclamptic status was found in 36.37% of patients. Other poor prognostic factors were Glasgow score of less than nine (9.09%), shock (7.27%), mechanical ventilation (58.18%) and complications. Mortality was 16.36%. Conclusion: The mortality of eclamptics in the intensive care units of CHU-MEL and CNHU-HKM was high. Poor prognostic factors were a history of preeclampsia or pregnancy-induced hypertension, severity of eclampsia and complications.

Anaphylaxis is a serious systemic reaction that is part of the general pattern of potentially fatal hypersensitivity reactions requiring immediate management. We report the case of a patient presenting to emergency with signs of malaria and pneumonia who was diagnosed with grade 4 anaphylaxis following antibiotic injection in the emergency department. The patient was 30 years old, with no previous history of anaphylaxis, and presented to the emergency department with fever, dry cough, headache and dizziness associated with prostration. Physical examination showed stable hemodynamics (BP = 110/80 mmHg, HR = 95 p/min,) and respiratory function with SpO2 = 98%, HR = 22 c/min and crepitus rales at the base of the lungs. The laboratory work-up carried out in the emergency department revealed a biological inflammatory syndrome associated with hyperleukocytosis of 11,260/mm3, a positive thick drop with GE(+) dp = 1183 T/microlitre;blood glucose = 0.83 g/l;Covid 19 RDT = (negative). A diagnosis of malaria and pneumonia was made and antibiotic therapy (ceftriaxone) and artesunate were indicated. During the injection of ceftriaxone 1 g, the patient became agitated, followed by cardiorespiratory arrest, confirming the diagnosis of stage 4 anaphylaxis. Treatment consisted of stopping the ceftriaxone injection, external cardiac massage and ventilation, intravenous adrenaline and vascular filling, which enabled the patient to recover and stabilize. The diagnosis of anaphylaxis is clinical. Early administration of adrenaline is the mainstay of treatment.

We present results of a series of experiments aimed at finding the most direct fingerprints of a phenomenon of nuclear chirality. These experiments brought a detailed knowledge of the so called partner bands in 132La, 128Cs and 126Cs including absolute values of E2 and M1 transition probabilities obtained through the DSA (Doppler Shift Attenuation) method. Considering the indirect character of observables such as energies and transition rates we proposed measurement of the g-factor of a chosen state as a direct, ultimate test of chirality. Our experiment on the bandhead of partner bands in 128Cs showed feasibility of this approach. Measured value of the g-factor which suggests non-chiral character of this state leads to another puzzle in the chirality studies — how the chirality emerges with increasing spin of levels along a partner band.

Predictive Study of Trace Metal Pollution of Gold Panning Sites in Birimian Formations: Case of the Yaouré Furrow (Côte d’Ivoire)

Open Journal of Applied Sciences 2024年第7期14卷 1691-1714页

The present study was carried out on small-scale gold mining sites in the Yaouré region of Côte d’Ivoire. This region is geologically representative of the Birimian formations (2.1 Ga) of West Africa. The aim is to determine the potentially toxic trace metals (TMEs) generated by these sites, with a view to preventing possible contamination and/or metal pollution of the waters that provide fish products for local populations. To this end, a sampling campaign was carried out, resulting in the collection of 20 mining waste samples analyzed by X-ray fluorescence spectrometry (XRF) and 10 by X-ray diffractometer (XRD). The XRF analysis detected 06 predominant TMEs: arsenic, chromium, copper, nickel, zinc and vanadium. Statistical analysis was carried out to determine the distributions and correlations between these ETMs. To assess contamination and/or pollution levels, the following indices were calculated on the basis of reference concentrations of upper continental crust MTEs: Enrichment Factor, Geo-accumulation Index, Concentration Factor, Degree of contamination and those related to ecological risks. The results of statistical analyses and indices have shown that arsenic and chromium are the most predominant and can be, depending on the chemical form, potentially more toxic. The results of the DRX analysis show the occurrence of several minerals carrying these two MTEs, especially that of a rare mineral, Stenhuggarite, an arsenic oxide linked to hydrothermal veins. The majority of gold mining operations in West Africa are located in the birimian zone, hence the need for environmental monitoring by the relevant authorities, to prevent potential ecological risks to water and possibly health risks via the food chain.

Investigating environmental quality among G20 nations: The impacts of environmental goods and low-carbon technologies in mitigating environmental degradation

引用

Geoscience Frontiers 2024年第1期15卷 84-96页

作者： ernest Baba Ali Samira Shayanmehr Riza Radmehr Richard Bayitse Ebenezer Agbozo Department of Economics University for Development StudiesTamale P.O.Box TL1350Ghana Department of Agricultural Economics Ferdowsi University of MashhadIran Council for Scientific and Industrial Research Institute of Industrial ResearchAccra P.O.Box LG 576Ghana Department of Big Data Analytics and Methods of Video Analysis Ural Federal University19 Mira Str60002 EkaterinburgRussia

Environmental goods and low-carbon technologies have long been identified as having the potential to drive long-term economic progress without compromising environmental quality. However, their exact role in mitigating environmental degradation are yet to be unravelled. In addressing this shortfall, the extant literature relied on research funding and patent application as proxies for green technologies. Having established the weaknesses in the use of these variables as proxies for green technologies, this study explored the role of trade in environmental goods and low-carbon technologies in boosting environmental quality among G20 nation using a panel dataset from 1994 to 2018. The study employed the Method of Moment quantile regression for the model estimation and the Ridge regression, Discroll-Kraay standard error, and the Newey-West standard error estimators to test the robustness of our findings. Our findings indicate that whereas environmental goods promote environmental quality, low-carbon technologies decrease same. Also, the study found economic growth to exert an aggravating effect on environmental quality, while foreign direct investments, natural resource rents, human capital development, and renewable energy consumption exert positive influence on environmental quality. Based on the findings of the study, G20 nations are encouraged to improve green market structures to improve the trade in environmental goods and low-carbon technologies. Also the share of renewable energy sources in the overall energy basket must be improved to help improve environmental quality.
