Khat (Catha edulis Forsk) is a plant consumed by many people in Eastern Africa, including Ethiopia, and Southern Arabia to be stimulated. There are several human and animal studies on khat that provide information about its toxic effects. However, the potential toxic effects of khat on embryos and fetuses have not been elucidated. The aim of the present study was to investigate the embryotoxic and fetotoxic effects of khat exposure during the earliest period of gestation in rats. Pregnant Wistar albino rats were treated with khat extract at 250, 500, and 750 mg/kg doses from day 6 through day 12 of gestation. The treatment was delivered by gavage. Embryos and fetuses were recovered on gestational day 12 or day 20, respectively, and were quantitatively and qualitatively assessed for developmental anomalies. Placentae from the treatment and control groups were investigated for histopathological effects. Results of the present study showed that khat exposure during pregnancy had dose-dependent toxic effects in rat embryos and fetuses. Prenatal growth retardation such as reduced fetal weight and crown-rump length was observed in near-term fetuses, especially, in animals treated with the highest dose of khat ( p < 0.05 ). Growth retardation and developmental anomalies were also observed in day 12 embryos of khat-treated rats. Maternal weight gain of the khat-treated group was also significantly lower than the control group. Cytolysis, decidual hypoplasia, and atrophy were observed in the placenta of the khat-treated rats. Findings of the present study revealed, for the first time, that exposure of pregnant rat to crude extract of khat causes embryotoxic and fetotoxic effects.

Background We already know that incorporating information and Communication technology (ICT) into every aspect of human activity result in significant change and makes tasks easier to complete. It can help in areas of healthcare systems and medical education. Therefore, this study aimed to assess utilization ICT and its associated factors among Arba Minch University College Medicine and Health Science students. Methods A cross sectional study design was conducted in June through August 2021 among under graduate students in college of medicine and health science at Arba Minch University, Ethiopia. A self-administered questionnaire was used to collect information on the students’ socio-demographic factors as well as the utilization ICT. The data entry form was prepared with Epi-data 3.1 versions software and STATA version 14 software was used to analyze the data. Results A total of 355 participants enrolled in the study, with a response rate of 98.34%. The percentage of students who used ICT was 55.77% [95% CI, 0.50, 0.60]. Regarding of field of study, health informatics students (84%) used the most ICT, while midwifery students (52%) used the least. Urban resident [AOR = 1.85, 95% CI = 1.08, 3.16], ICT knowledge [AOR = 3.8, 95% CI = 2.25, 6.40], having formal training of ICT [AOR = 1.9, 95% CI = 1.06,3.48], having IT in current course study [AOR = 2.2, 95% CI = 1.23, 3.84], and had good IT skill [AOR = 2.4, 95% CI = 1.34, 4.23] revealed a significant and positive correlation with the use of ICT. Conclusion In the current study previous residence, ICT knowledge, having formal training, having IT in current courses, and IT skill were significantly associated with student ICT utilization. Therefore, the university should continue to invest in professional development in order to improve teaching and student performance, as well as provide the college with student-centered ICT computer labs to encourage students to use technology.
