Effect of heating and enzymatic hydrolysis on casein cow milk sensitivity in Moroccan population

The objectives of the present work were first to evaluate the sensitivity to cow raw milk of the population of Fez, and then to study the effect of heating and pepsin hydrolysis on the allergenicity of casein. A cross-sectional study was carried out in Fez Hospitals, in which 1000 patients were recruited to establish a sera bank used to evaluate specific IgE to cow milk and to casein. Then, we evaluated the reaction of human IgE to heated and pepsin-hydrolysed casein. The results showed that 11.5% of the population studied self-reported reactions to foods. From them, 3.6% reported allergy to milk. Evaluation of specific IgE to cow raw milk showed that 11.9% of patients presented higher specific IgE levels. The treatments of casein indicated that both heating and pepsin hydrolysis totally decreased its binding on the human IgE

Moroccan validation of the dysfunctional beliefs and attitudes about sleep (DBAS-16) scale

Purpose: The international DBAS-16 questionnaire is an instrument that measures dysfunctional beliefs and attitudes toward sleep in the general population. It was initially developed in English in Canada by Charles Morin's team. Objective: This study aims to translate and adapt the DBAS-16 questionnaire on beliefs and attitudes toward sleep into Moroccan languages (Tamazight and Arabic) and validate it on 174 participants. Materials and methods: From September 2019 to March 2020, 174 Moroccan participants in three cities -Fes, Kénitra, and Khémisset- participated in the adaptation and validation of DBAS-16. We translated, adapted, and validated the test into Moroccan Tamazight and Arabic according to the recommendations of “Beaton et al.” We evaluated the acceptability, reliability, central tendency, and validity of DBAS-16 in the Moroccan Arabic dialect version. Results: Acceptability and reproducibility were satisfactory. The internal coherence was strong (Cronbach α = 0.773). The average overall score (standard deviation) on the Moroccan DBAS-16 scale was 1.71. The sub-scale scores were 2.20 for Consequences, 2.07 for Worry/Helplessness, 2.75 for Sleep Expectation, and 2.23 for Medication. Conclusion: Our study's results were similar to those of other countries. Moroccan versions of DBAS-16 will facilitate further studies on sleep attitudes in Morocco and elsewhere
