    Objective: It is widely acknowledged that patients with cancer commonly experience malnutrition, and some individuals may adopt specific dietary trends. This study investigated the prevalence of malnutrition and dietary trends among Algerian cancer outpatients undergoing chemotherapy. Material and methods: This cross-sectional, descriptive study was conducted from January to October 2023 with 71 cancer outpatients undergoing chemotherapy. Malnutrition risk was evaluated using the Malnutrition Screening Tool (MST). The questionnaire also collected the occurrence of nutrition impact symptoms, the avoidance of specific food groups, and the use of oral nutritional supplements and dietary supplements. Results: Malnutrition risk was identified in 57.7% (41 cases) of participants. Nutrition impact symptoms were reported by 59.2% (42 cases) of patients. A total of 36 of the patients (50.7%) altered their eating habits by avoiding at least one food group. Among malnourished cancer outpatients, only five used oral nutritional supplements. Dietary supplements were used by 23.9% (27/71) of the patients after cancer diagnosis. Conclusion: Our findings underscore the necessity for a systematic malnutrition assessment in cancer patients. Qualified clinicians should provide nutritional awareness to enhance the quality of life for these patients.

    Selectivity control in the reaction between 2-hydroxyarylaldehydes and 4-hydroxycoumarin. Antioxidant activities and computational studies of the formed products
    (Elsevier, 2021) Ould Lamara, Kamilia; Makhloufi-Chebli, Malika; Benazzouz-Touami, Amina; Terrachet-Bouaziz, Souhila; Hamdi, Nejla; Silva, Artur M.S.; Behr, Jean-Bernard
    A series of 6H,7H-7-(4-Hydroxy-3-coumarinyl)[1]benzopyrano[4,3-b][1]benzopyran-6-ones 4a-g and 3-(2-hydroxybenzoyl)-2H-chromen-2-ones 5a-g derivatives were synthesized by reaction of 4-hydroxycoumarin with 2-hydroxyarylaldehydes 2a-f or 2-hydroxynaphtaldehyde 2g using different solvents and acid/base catalysts. The approach relies on a regioselective cascade reaction involving one/two molar equiv of the 4-hydroxy coumarin iteratively acting as active methylene substrate in a Knoevenagel condensation and in a Michael addition. The structures of all compounds were established by IR, mass spectrometry, 1H-NMR and 13C-NMR. Antioxidant activity of the synthesized compounds were determined using the DPPH scavenging assay, best results being obtained with 5b (IC50 = 236 µg/mL). Computational studies showed that the compounds bind in the ATP-binding site of p38 MAPK, in a same manner than known polyaromatic potent inhibitors. The synthesized compounds might be considered further for cancer therapy
