To determine the prevalence of functional hypogonadotropic hypogonadism (FHH) from nutritional origin, and to study its clinical and biological characteristics. Population and methods. This retrospective study was conducted on 32 cases of FHH [secondary to Chronic Diseases + Constitutional Delay of Growth and Puberty (CDGP)], from a series of 125 patients evaluated for delayed puberty (DP) in the Endocrinology Department of the University Hospital Center of Constantine, between 2000 and 2010, and follow-up for at least 5 years. The diagnosis of malnutrition was clinical, according to the American Academy of Nutrition and Dietetics consensus. Each patient received a general check-up and a gonadotropic and thyrotropic hormonal assay. Other etiological explorations were clinically guided. FHH group was compared with isolated hypogonadotropic hypogonadism (IHH) group. Results. FHH constituted 26% of the series [21 boys/11 girls, (p<0.5)] vs 24% of IHH group. Secondary HHF represented 20% of cases in the series against 6% of CDGP. Malnutrition represented 27% of the series, 11% of which were directly responsible for delayed puberty (DP). Protein-energy undernutrition and iron deficiency anemia, due to inadequate intake, accounted for 62% of nutritional causes. There was a break in the growth curve in 97% of FHH vs 26% of IHH patients (p<0.001). FHH tripled the risk for developing growth retardation. Testicular volume of FHH group was 2.82±0.73 mL (2.69±0.4 mL in patients with malnutrition) vs 2.09±0.87 mL for IHH group (p<0.05). Conclusion. Despite therapeutic progress, DP in CD is common, representing a severity indicator, and poor control of CD. Prevention of FHH requires early detection, nutritional supplementation, and good control disease.","PeriodicalId":254787,"journal":{"name":"Nutrition &amp; Santé","volume":"254 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114292114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The natural plant resources are products with high added value, used in various fields for the manufacture of a wide variety of products. Objective. The purpose of this study was the physicochemical and chromatographic characterization of Ziziphus jujuba seeds vegetable oil, and the evaluation of their antioxidant and anti-inflammatory activity. Material and methods. Seeds oil extraction was done by soxhlet. Fatty acid content was determined by gas chromatography (GPC). Organoleptic and physicochemical characteristics were determined, and antioxidant activity was evalua-ted by diphenyl-picryl-hydrazyl (DPPH) test and -carotene bleaching. Anti-inflam-matory activity was essayed using carrageenan-induced plantar edema model in mice. Results. Extracted seeds oil had an extraction yield of 3.4%. GPC characterization sho-wed the presence of 12 fatty acids with a predominance of oleic acid (47.02%), and linoleic acid (37.40%). Physicochemical parameters of Ziziphus jujuba seeds oil showed an acidity of 2.05%, a saponification value of 198.17 mg KOH/mL, and refractive index of 1.471±0.00. This oil expressed a significant antiradical activity for the DPPH test, and low for that of β-carotene. In vivo study of edema induction in mice showed that oil had a maximum effective effect in inhibiting oedema (55.89±0.03%), at the first hour, compared to Diclofenac (19.88±0.12%), at the same hour. Conclusion. These results highlight the fatty acids richness of Ziziphus jujuba seeds oil with antioxidant and anti-inflammatory effects.

This study aimed to evaluate Algerian consumers awareness and attitudes toward organic food products, and identify factors influencing their decision to purchase these organically grown foods. Material and methods. Survey data were obtained from 429 consumers via a 32-scale structured questionnaire, and evaluated with SPSS 25.0 and AMOS 25.0 using confirmatory factor analysis (CFA), and structural equation modeling (SEM). Hypotheses were verified by evaluating data via SEM, where mediating variables were attitude and purchasing intention. Results. The main reasons for Algerian consumers to consume organic food were health concerns, followed by environmentally friendly, pesticide-free, and better taste. Moreover, three factors namely health consciousness, subjective norms, and perception of availability were revealed to influence consumer buying behaviour towards organic food products. This occurred either by a direct effect such as availability perception or by a partial mediation of purchase intention, like subjective norms or by full mediating of attitude toward organic food, and purchase intention as the health consciousness factor did.

COVID-19 is the pandemic of the century with the unusual circumstances it generated. Subsequently, there has been medical and human scarcity of resources leading to the health system collapse, especially in third world countries. Objective. To support the white army in grasping the pandemic behavior, several studies have pointed to the existence of patient-related factors affecting COVID-19 patients’ mortality-risk. In the current study, Artificial Neural Network (ANN) has been employed to predict COVID-19 mortality. Material and methods. In particular, the modeling phase was done using a database of 684 samples collected from Mohamed Seddik Ben Yahia Hospital of Jijel, with antecedent diseases and blood biomarkers data of patients. Firstly, 18 parameters were selected in the input layer based on the literature recommendation and expert medical team consultation. Furthermore, the optimal inputs have been modeled using the ANN, and their performance was assessed through four performance measures (sensitivity, specificity, precision, and accuracy). Results. The comparative study proved the effectiveness of (18-12-2) model trained by Tansig transfer function, which displayed a higher performance in predicting COVID-19 mortality, compared to other models proposed in the literature. Afterward, the proposed optimal model was utilized to develop a GUI public interface by Matlab software. Conclusion. Finally, a reliable and easy-to-use graphical interface is generated in the current study dubbed “CoviSurv2021”. This latter will be very helpful for the medical staff to select priority patients who have upper urgency to be hospitalized, prioritize patients when the hospital is overcrowded, and gain time to provide the care needed.","PeriodicalId":254787,"journal":{"name":"Nutrition &amp; Santé","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128457419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
