Cardiac involvement in systemic lupus erythematosus: Interest of 2D global longitudinal strain.

Background: Systemic lupus erythematosus (SLE) is a chronic multisystem autoimmune disease of undetermined etiology. Cardiac involvement is common in SLE and constitutes one of the main causes of mortality. More recently, new ultrasound imaging techniques, such as transthoracic ultrasound (TTE) with strain evaluation, have appeared and seem promising for the detection of cardiac involvement.

[Rheumatic cardiopathies and its risk factors: about 50 cases].

Introduction: Acute rheumatic fever (ARF) is a multi-systemic disease, in which cardiac involvement is the most serious major manifestation of disease. The aim of this study was to analyse cardiac involvement in children with ARF and his risk factors.

Materials And Methods: It were a retrospective study including all children under the age of 14 years who were hospitalized for ARF in the pediatric department of the CHU Hédi Chaker of Sfax, during a period of twelve years (2010-2022).

Recent advances in selective allergies to mammalian milk proteins not associated with Cow's Milk Proteins Allergy.

Cow's milk proteins allergy (CMA) is an atypical immune system response to cow's milk and dairy products. It's one of the most common food allergies in children affecting 8% of the total pediatric population pediatric population. This comprehensive review examines recent studies in CMA, especially regarding mammalian milk allergies such as goat's, sheep's, buffalo's, camel's, mare's and donkey's milk allergies in order to increase awareness of these selective allergies and to reduce allergy risks for those who have them.

Synthesis and comparative study of the structural and optical properties of binary ZnO-based composites for environmental applications.

The development of photoactive systems to solve serious environmental problems is a key objective of researchers and remains a real challenge. Herein, n-p heterojunction ZnO-based composites were developed to achieve better photocatalytic performance in methylene blue (MB) degradation under natural solar irradiation. The hydrothermal technique was used to synthesize zinc oxide (ZnO)/metal oxide (MO) composites, with a molar ratio of 1 : 1 (MO = MnO; FeO; CuO; NiO).
