The inverted triplesalen ligand H6feldMe has been synthesized from 2,4,6-triformyl-phloroglucinol and a ketimine salen half-unit in a convergent synthesis. NMR, IR, and UV-vis spectroscopy reveal that this ligand is not in the O-protonated tau- tomer but in the N-protonated tautomer with substantial heteroradialene contribution. This ligand and the conventional triple- salen ligand H6talent-au2 have been used to synthesize the trinuclear Fem complexes [（feldMe）（FeCl）3] and [（talent-Bu2）（FeC1）3], respectively. The molecular structures of these complexes were obtained by single-crystal X-ray diffraction. Two trinuclear Fem complexes of [（feldMe）（FeCl）3] dimerize via two Fe-phenolate bonds, whereas due to steric hindrance no dimerization is observed for [（talent-Bu2）（FeC1）3]. The structural data also reveal some heteroradialene contribution in the trinuclear complexes. Whereas UV-vis and MOlSbauer spectroscopy are not suitable to distinguish between the two complexes, FT-IR spectra show characteristic features due to the different substitution patterns of the conventional and the inverted triplesalen ligands. Another handle is provided by electrochemistry. Whereas both complexes exhibit an irreversible oxidation wave （0.94 V vs. Fc＋/Fc for [（feldMe）（FeC1）3] and 0.84 V vs. Fc~/Fc for [（talent-Bu2）（FeC1）3]）, which is assigned to the oxidation of the central backbone, higher potential oxidations are reversible for [（talent-Bu2）（FeC1）3]） but irreversible for [（feldMe）（FeC1）3]. This is attributed to the reversible oxidation of the terminal phenolates in the di-tert-butyl substituted [（talentBu2）（FeCl）3] in contrast to the mono-methyl-substituted phenolates in [（feld^ae）（FeC1）3]. The magnetic properties of [（talen^-Bu2）（FeC1）3] reveal a very small ferromagnetic coupling with significant zero-field splitting of the Feul S = 5/2 ions. In contrast, the dimerization of two trinu- clear complexes in [（feldMe）（FeCl）3] results in antiferromagnetic interactions between the two pheno

Hepatobiliary & Pancreatic Diseases International 2024年第5期23卷 509-514页

作者： Rodrigo Garcés-Durán Laurent Monino Pierre H Deprez hubert Piessevaux Tom G Moreels Department of Gastroenterology and Hepatology Universitécatholique de LouvainCliniques Universitaires Saint-LucAvenue Hippocrates 101200 BrusselsBelgium

Background: Endoscopic treatment of biliopancreatic pathology is challenging due to surgically altered anatomy after Whipple's pancreaticoduodenectomy. This study aimed to evaluate the feasibility and safety of single-balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography(SBE-ERCP) to treat biliopancreatic pathology in patients with Whipple's pancreaticoduodenectomy surgical variants. Methods: We retrospectively analyzed 106 SBE-ERCP procedures in 46 patients with Whipple's variants. Technical and clinical success rates and adverse events were evaluated. Results: Biliary SBE-ERCP was performed in 34 patients and pancreatic SBE-ERCP in 17, including 5 with both indications. From a total of 106 SBE-ERCP procedures, 76 were biliary indication with technical success rate of 68/76(90%) procedures and clinical success rate of 30/34(88%) patients. Mild adverse event rate was 8/76(11%), without serious adverse events. From a total of 106 SBE-ERCP procedures, 30 were pancreatic indication with technical success rate of 24/30(80%) procedures( P = 0.194 vs. biliary SBEERCP) and clinical success rate of 11/17(65%) patients( P = 0.016 vs. biliary SBE-ERCP). Mild adverse event rate was 6/30(20%)( P = 0.194 vs. biliary SBE-ERCP), without serious adverse events. After SBE-ERCP failure, endoscopic ultrasound-guided drainage, percutaneous drainage and redo surgery were alternative therapeutic options. Conclusions: Biliopancreatic pathology after Whipple's pancreaticoduodenectomy variants can be treated using SBE-ERCP without serious adverse events. Technical and clinical success rates are high for biliary indications, whereas clinical success rate of pancreatic indications is significantly lower. SBE-ERCP can be considered as first-line treatment option in this patient group with surgically altered anatomy.

Open Journal of Endocrine and Metabolic Diseases 2024年第2期14卷 15-25页

作者： Annelie Kerekou Hode hubert Dedjan Fréjus Alamou Department of Endocrinology Metabolism Nutrition of National University Hospital Center-hubert Koutoukou Maga Cotonou Bénin Department of Medicine and Medical Specialties of the Departemental University Hospital Center of Ouémé/Plateau Porto-Novo Bénin

Introduction: Since its creation in 2017 by the European community, the EU-TIRADS classification has enjoyed an excellent reputation in several countries around the world. Indeed, several studies conducted in these countries testify to the effectiveness of this tool for the management of nodular thyroid pathology. However, in Benin, the contribution of this classification has not yet been evaluated. It is therefore to overcome this inadequacy that we undertook this study. Objective: Participate in improving the diagnostic and therapeutic management of thyroid nodules at the CNHU HKM in Cotonou and at the CHUZ in Suru-Léré. Methods: This is a cross-sectional study with retrospective data collection spread over a period of 3 years 5 months, from January 2019 to May 2022 and carried out jointly in the Endocrinology Metabolism Nutrition and ORL-CCF departments of the CNHU HKM of Cotonou and in the ORL-CCF department of the CHUZ of Suru-Léré. The study population consisted of patients who consulted the University Clinic of Endocrinology Metabolism Nutrition, the University Clinic of ORL-CCF of the CNHU-HKM and the University Clinic of ORL-CCF of the CHUZ of Suru-Léré for thyroid nodule and who have had surgery. The study data was collected from patients hospitalization records using a survey form. Results: On ultrasound, according to the EU-TIRADS classification, 56.8% of nodules presented a low risk of malignancy (EU-TIRADS 3) compared to respectively 19.8%;23% and 2.5% of nodules with zero (EU-TIRADS 2), intermediate (EU-TIRADS 4) and high (EU-TIRADS 5) risk of malignancy. Regarding the performance of this classification, it is sensitive in 37.5% of cases and has a specificity of 78.5% with a PPV (Positive Predictive Value) and a NPV (Negative Predictive Value) respectively of 6.6 % and 91.6%. Furthermore, the bivariate correlations revealed that the size of the nodule was significantly associated with the malignancy of the nodule (p = 0.014) and the calculated value o

Introduction: Diabetes is a major public health problem. Medicinal plants are frequently used either combine with industrial treatment or exclusively, in Africa and particularly in Benin. Our study aims to identify the different medicinal plants used by diabetic patients at the CNHU-HKM. Method: we carried out a descriptive and analytical cross-sectional study. It took place at the University Clinic of Endocrinology, Metabolism and Nutrition of CNHU-HKM over a of 3 months period from 20th of June to 16th of September, 2022, over diabetic followed-up. Results: One hundred and seventy-three (173) patients were gathered using an anonymous inquiry form. In the study population, the age of the patients varied between 31 and 75 years with an average age of 59 +/− 1.43 years, women represented 59% with a sex ratio (male/female) of 0.69. Sixty-five (65) or 37.6% of the population had used medicinal plants. Among given reasons for using medicinal plants were, mainly the positiveness on a third party. Data analysis outcome twenty-nine species of plants belonging to twenty (20) botanical families, the most represented being the Annonaceae and Fabaceae. The most used species are Phyllanthus amarus (hlenwé in fon), Mangifera indica (mangatin in fon), Momordica charantia (gninsikin in fon), Combretum micranthum (kinkéliba in fon), and Picralima nitida (ayorkpè in fon). Most used parts of the plants are the leaves. The recipes are prepared mainly by infusion and are administered exclusively by mouth. Most of the patients who used the hypoglycaemic medicinal plants were satisfied and no adverse effects were reported by them. Conclusion: Hypoglycaemic medicinal plants could be subjected to pharmacognosy and marketed due to their richness in active components, after further toxicological studies.

Introduction: Predictions on the prevalence of diabetes mellitus, according to the International Diabetes Federation, indicated 9.3% in 2019 and nearly 10.9% of the general population in 2045. In Benin, the increase in this prevalence, according to the World Health Organization (WHO), is constantly increasing. Diabetic foot is one of its most common complications. The aim of this work was to study the prognostic factors of diabetic foot in the Department of Endocrinology, Metabolism and Nutrition of the CNHU-HKM of Cotonou. Patients and method: This is a descriptive and analytical retrospective study of the prognostic factors of diabetic foot over a period of 3 years from January 2019 to December 2021 in patients who have been hospitalized or followed on an outpatient basis for diabetic foot in the Endocrinology, Metabolism and Nutrition Department of the CNHU-HKM of Cotonou. Results: A total of 112 patients were included in this study. The average age of the patients was 59.70 ± 2.10 years. A male predominance was noted with a sex ratio (M/F) of 1.7. Mixed gangrene and phlegmons were the most common lesions. According to the classification of diabetic feet according to the University of Texas, 59.1% of patients had a 100% risk of amputation. Ten patients died from sepsis (8.9%). The average blood glucose on admission was 2.74 ± 0.23 g/l, reflecting the glycemic imbalance in these patients. There is a statistically significant association between the duration of progression of diabetes, the type of lesion and amputation. Patients whose diabetes has lasted more than 30 years and patients who are not monitored have a greater risk of death. Conclusion: Diabetic patients most often consulted at a late stage, compromising conservative treatment. The duration of diabetes and the type of lesion on admission were the main factors leading to amputation, thus compromising the functional prognosis. As for death, it was mainly linked to irregular monitoring of diabetes and the
