Risk Factors Involved in Postural Disorders in Children and Adolescents.

Postural disorders in children and adolescents have an increasing incidence. The aim of this study was to identify the type of postural defects in school-age and preschool children, as well as the external risk factors determined by an inadequate lifestyle. The research included 134 children aged between 5 and 18 years, in whom postural defects were identified.

Clostridium difficile infection in pediatric patients (Review).

infection (CDI) is the most common cause of healthcare-associated diarrhea and among adults, the worldwide incidence rate of the infection is increasing. There is a small amount of data in the literature for pediatric patients, but most indicate an increasing trend. is a constituent of the normal microbiota; however, under specific conditions that cause a disruption of the normal bacterial flora, colonization of and the released toxins that cause inflammation and mucosal damage occurs.

Immunoexpression of Ki67, p53 and cyclin D1 in osteosarcomas.

The main malignant tumor of the bone tissue is represented by osteosarcoma, neoplasia with a reserved prognosis and an unpredictable evolution, often aggressive. Cell cycle disruption is one of the complex biomolecular mechanisms involved in the progression of osteosarcomas. In this study, we analyzed the immunoexpression of Ki67, p53 and cyclin D1 for 18 primitive osteosarcomas in relation to the clinicopathological prognosis parameters of the lesions.

Identification and mapping of Algerian island vegetation using high-resolution images (Pléiades and SPOT 6/7) and random forest modeling.

Despite their proximity to the coast, few studies have focused on identifying and mapping the vegetation of Algerian islands and islets. To fill this lacuna, our work, using satellite images and machine learning methods, is mainly aimed at identifying and mapping the main vegetation groups on a few islands, while evaluating the effectiveness of the random forest classifier, which is effectively used in the study of the vegetation of large areas. However, despite the high heterogeneity of their vegetation cover, the use of very high-resolution images (Pléaides and SPOT 6/7), through the fusion bands and derived bands (NDVI), has allowed the elaboration of a fairly precise vegetation map that can be used for the preparation of management and protection plans for these habitats.
