Glycated Haemoglobin Determination in the Biological Follow-Up of Diabetic Subjects Admitted to the endocrinology department of the CNHU-HKM of Cotonou

Journal of Diabetes Mellitus 2023年第1期13卷 36-44页

作者： Annelie Kerekou Hode Hubert Dedjan Nesme Aboudou department of endocrinology Metabolism and Nutrition CNHU-HKM Cotonou Benin

Introduction: One of the biological markers for monitoring glycaemic control in diabetic patients is glycated protein. The definition of a reference method to improve the accuracy of measurement tools is necessary. The aim of our study was to assess the glycemic control of diabetic patients based on glycated hemoglobin. Patients and Method: This is a descriptive cross-sectional study conducted in April 2021 at the national university hospital center (CNHU-HKM) of Cotonou. All patients who consulted during the period and who gave their consent were included. After collecting the blood samples according to the classical standards of the pre-analytical phase, we measured the blood glucose level and the HbA1c. Results: The mean blood glucose level of the patients was 1.52 ± 0.16 g/L with extremes of 0.80 g/L and 3.5 g/L. The mean HbA1c proportion was 8.39% ± 0.60% with a minimum and maximum value of 5.40% and 16% respectively. We also noted that the mean body mass index (BMI) of the patients was 28.61 ± 1.46 Kg/m2 with extremes of 17.50 Kg/m2 and 46.02 Kg/m2. Oral anti diabetic and hygienic-dietary measures were used by 44 patients (80%) and hygienic-dietary measures (HDM) only used by 9.09%. A frequency of 87.53% of patients had at least one degenerative complication. Retinopathy was the most observed degenerative disease (36.36%) followed by cardiovascular disease (25.45%). Conclusion: This study showed that there is a poor correlation between fasting blood glucose and glycated haemoglobin levels, which could be due to several biological and clinical reasons. It also showed that despite the respect of hygienic dietary measures and a well conducted treatment, it is difficult to obtain a satisfactory glycemic balance in obese patients.

Ethanol-assisted synthesis of a Ni single-atom catalyst with poriferous 3D framework for efficient cascade CO2 electroreduction

Rare Metals 2024年第9期43卷 4612-4619页

作者： Feng Wu Shi-Qi Wang Sebastian Kunze Xiao-Ping Gao Pei-Qun Yin Yu-En Wu Division of Life Sciences and Medicine Department of Endocrinology School of Chemistry and Materials Science The First Affiliated Hospital of USTC University of Science and Technology of China department of Chemistry Seoul National University School of Biomedical Engineering Anhui Medical University

The electroreduction of carbon dioxide to generate multicarbon products is significant for achieving a carbon-neutral economy. However, the selectivity for multi-carbon products faces several challenges, such as the intricate nature of the multistep hydrogenation processes, slow reaction kinetics and the bicarbonate precipitate issue caused by alkaline conditions. These factors hinder the extensive utilization of this reaction. Herein, we successfully developed and implemented a tandem electrolyzer cascade to separate and optimize the complex elementary reactions involved in the process of multi-carbon production. This approach enables us to enhance the Faradaic efficiency (FE) of each step, consequently improving the overall performance of the system. An ethanol-assisted ionic-exchange method was utilized to synthesize a Ni
