In vitro Biological activities of aqueous extracts of Tetrapleura tetraptera (Schumach&Thonn.) taub.andAframomumcitratum(C. Pereira) K.Schum from three Agroecologic zones in Cameroon: The polyphenol variabilities

The aim of this study is to study few phytochemical, nutritional and physicochemical constituents of twelve samples of Tetrapleura tetraptera (Schumach&Thonn.) taub.and nine of Aframomumcitratum(C. Pereira) K.Schum fruits collected in three Agro-ecologic zones in Cameroon: Bimodal forest zone (ZONE V), Unimodal forest zone (ZONE IV) and highlands zone (ZONE III). T. tetraptera fruits were spread over three Ago-ecological Zones (Zones V, IV, III) and A. citratum fruits were spread over two AEZ (Zones V, IV). Various analysis (dry matter, ash, total fat, crude proteins, total sugars, crude fibre contents; energy, water activity and pH; Fe, Ca, Mg and K contents; total polyphenols and flavonoids contents) using standard analytical, colorimetric, spectroscopy and spectrophotometric procedures were used. Phenolic compounds characterization was done on both spices aqueous extracts using HPLC. The results showed that concerning T. tetraptera samples, crude fibre content is significantly (p<0.05) high on samples from Zones IV and III while samples from Zone V possess more sugars, calories, minerals and phenolic compounds. About A. citratum, samples from Zone IV are the most sweet and the ones from Zone V contain more protein, fiber, phenolic and minerals (especially samples from the East region) contents.On T. tetraptera aqueous extracts, Gallic, chlorogenic, benzoic, 2-OH cinnamic, salycilic acids and flavone, gallocatechin, epigallocatechin gallate, naringin, phlorizin were among the predominant compounds identified. Localities from the littoral region (Nyanon, barebakem, NkwangsiII, MantemII) corresponding to Zone IV and III possess the smallest total polyphenols contents. However, the spices from Zone III have the lowest. About A. citratum, samples from Zone IV are the most sweet and the ones from Zone V contain more protein, fiber, phenolic and minerals (especially samples from the East region) contents. On aqueous extracts, a total of six dominant (in terms of quantity and frequency) phenolic compounds (Gallic, Chlorogenic, Protocatechuic, 2-OH Cinnamic, Caffeic, p-Coumaric acids) and five flavonoids (epigallocatechin gallate, resveratrol, phlorizin, rutin, epicatechin, luteolin) were observed on the extracts. Theobromine is present only in spices from the East region, while Kojic acid is present on spices from centre and Littoral regions. Samples from Zone IV (Lolodorf, Nyanon and Bonepoupa II) possess the smallest amounts of Total polyphenols. For both species, total phenolic acids content and total flavonoids content of aqueous extracts significantly (p<0,05) varied from one locality to another

Low incidence of SARS-CoV-2, risk factors of mortality and the course of illness in the French national cohort of dialysis patients

International audienceThe aim of this study was to estimate the incidence of COVID-19 disease in the French national population of dialysis patients, their course of illness and to identify the risk factors associated with mortality. Our study included all patients on dialysis recorded in the French REIN Registry in April 2020. Clinical characteristics at last follow-up and the evolution of COVID-19 illness severity over time were recorded for diagnosed cases (either suspicious clinical symptoms, characteristic signs on the chest scan or a positive reverse transcription polymerase chain reaction) for SARS-CoV-2. A total of 1,621 infected patients were reported on the REIN registry from March 16th, 2020 to May 4th, 2020. Of these, 344 died. The prevalence of COVID-19 patients varied from less than 1% to 10% between regions. The probability of being a case was higher in males, patients with diabetes, those in need of assistance for transfer or treated at a self-care unit. Dialysis at home was associated with a lower probability of being infected as was being a smoker, a former smoker, having an active malignancy, or peripheral vascular disease. Mortality in diagnosed cases (21%) was associated with the same causes as in the general population. Higher age, hypoalbuminemia and the presence of an ischemic heart disease were statistically independently associated with a higher risk of death. Being treated at a selfcare unit was associated with a lower risk. Thus, our study showed a relatively low frequency of COVID-19 among dialysis patients contrary to what might have been assumed
