The physical appearance of older people in the commune of Ouidah seems to be correlated with the economic level of the people. However, it is now clear that the nutritional status of older people is a key element for natural ageing and improved quality of life. Objective: To identify the factors associated with undernutrition among people aged 60 years and over in the commune of Ouidah in southern Benin. Methods: This was a cross-sectional analytical survey that took place between May and June 2020 and involved older people aged 60 and over selected by cluster sampling using a questionnaire and an interview guide. Their sociodemographic characteristics, health status, diet and the health system in their environment were explored.

The virulent Escherichia coli strains are responsible for extraintestinal infections. However, no past studies have been undertaken via the presence of virulence genes, ability of biofilms formation and the frequency of Escherichia coli pathovars recovered from different butcheries and slaughterhouses in Tunisia. The aims of this study was to investigate 1-) the prevalence of pathogenic E. coli strains isolated from bovine, ovine, and poultry meat in Tunisia, 2-) to determinate the antibiotic resistance profiles, and 3-) to determine their biofilm-forming ability by three phenotypic methods .Totally, 36 E. coli isolates from meat of healthy animals (bovines, ovine, and chickens) collected from different butcheries and slaughterhouses were investigated by searching by PCR genes encoding virulence factors (hlyA, stx1, stx2, fimH, papC, eaeAet papG allèle III, ibeA, iutA, and antibiotic susceptibility testing. Biofilm production was detected by three phenotypic: Congo Red Agar (CRA) method, tube method (TM) and tissue culture plate (TCP) method. In addition, the genetic relationship of isolates was determined by PFGE.

Fisher exact test is one of most popularly used methods in modern data analyses. However, it is conservative because of discreteness. The mid-p method may reduce the conservativeness but it is defined by the factor 1/2, an extra term beyond data. This paper considers an adjustment defined by a data-based factor. The adjusted test is compared with other ten tests. Special attention is given to the comparison between the data-based factor and the factor 1/2. The standardized version of the adjusted test is asymptotically standard normal.

Analyze the clinical profile of the spine with osteonecrosis in sickle cell disease. 610 patients were followed-up in this study between 2000 and 2017. 98 osteonecrosis were identified, 48 in the lumbar spine, 40 in the thoracic spine and 10 in both spine segments. We analyzed sex, age, genotype, and pain. Magnetic resonances and radiographs of the spine were performed.
