Background: Myocardial Infarction carries a significant morbidity, psychological effects, and financial constraints for the patient and the family when it occurs at young age. However there is limited data on the clinical features of young adults with AMI in Egypt and the Middle Eastern region. We therefore sought to investigate the clinical profile, risk factors and angiographic variables of this age group in Egypt. Aim of the Work: To determine the clinical profile and prevalence of different risk factors including Cigarette Smoking, Tramadol use, Cannabis smoking, HDL & LDL levels, stressful lifestyle and bad sleeping habits in Egyptian patients presented with Myocardial Infarction for the first time at age ≥ 45 years. Methods: We conducted a cross sectional observational study on 106 consecutive patients aged ≤ 45 years admitted with 1st time myocardial infarction in the period between February 2018 and August 2018 at Ain Shams University, Egypt. Clinical, and Angiographic variables were recorded from all patients. Results: Out of 1207 patients admitted with 1st time MI, 106 were young that gave a prevalence of 8.8% in our center. Out of 106 patients, 101 were male. Mean age was 39.19 yrs. 71 patients had ST elevation myocardial infarction (MI) (67%) and 35 had non ST elevation MI (33%). Anterior wall MI was present in 49 patients (46.2%), inferior wall MI in 20 patients (18.9%) and lateral wall MI in 2 patients (1.9%). 93 patients (88%) were smokers, 31 patients (29.2%) were Tramadol users, 43 patients(40.6%) smoked cannabis, 50 patients (47.2%) had bad sleeping habits, 29 patients (27.4%) had high stress levels, 37 patients (34.9%) were hypertensive, 22 patients were diabetic (20.8%). Family history of CAD was present in 20 (18.9%) patients. Low High-density lipoprotein (HDL) was seen in 47 patients (44.3%), and high Low-density lipoprotein in 20 patients (18.9%). LAD was involved in 56% of patients, with a significant association between Tramadol use and LAD involvement. We found significant association between both Tramadol use and Cannabis smoking and the presence of Heavy thrombus burden in Coronary Angiography. Conclusion: AMI in the young almost exclusively occurs in male, Anterior wall MI is most common, with LAD being involved in around half of patients. Smoking, hypertension, low HDL, Tramadol use, Cannabis smoking, and bad sleeping habits are the major risk factors. Tramadol use was associated with significant affection of LAD. Tramadol use and Cannabis smoking were associated with high thrombus burden on coronary angiograph. [ABSTRACT FROM AUTHOR]

Abstract: Studies on the precursors of Nummulites gizehensis group and Nummulites partschi group from the Eocene of Egypt has permitted the identification of seven species. Two of these, namely Nummulites rushdisaidi n.sp. and Nummulites qenaensis n.sp. are new. This study suggests that the group might have evolved polyphyletically since the early Ypresian with more marked diversification during the Middle Eocene and attained maximum test size during Bartonian (Nummulites lyelli). This group has been studied in stratigraphic sequence, taking into consideration their geographic distribution. Some known Ypresian precursors such as Nummulites delaharpei and Nummulites mariettei (topotypes) and Nummulites rollandi are also described and illustrated for the first time. During the evolution, retrogenesis was noticed with species evolving from lax to tightly coiled whorls in microspheric forms, whilst the megalospheric forms become progressively lax internally and tighter externally, or vice versa. In addition, duplication of the spiral was noticed in N. qenaensis n.sp. Also, reflexive coiling expressing change in the course of the septa in the outer whorls has been noticed during the ontogeny in N. rollandi. [Copyright &y& Elsevier]

Objective: Acute myocardial infarction (AMI) is the main cause of cardiovascular events worldwide. AMI commonly occurs in elderly patients because of atherosclerotic process related to common risk factors. Consequently, the rupture of atheromatous plaque with deleterious sequela is the common etiology of the disease. However, there are less studied etiological factors in youth compared with the usual population. Therefore, this study aimed to examine the risk profile of Egyptian youth presenting with AMI., Methods: A study was conducted in 106 patients aged ≤45 years admitted with AMI in our university hospital to explore their clinical profile risk factors., Results: In the study, 71 (67%) and 35 (33%) patients presented with ST elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI). Anterior wall MI was predominant in 49 patients (46.2%). Moreover, 93 patients (88%) were smokers, 31 (29.2%) used tramadol, 43 (40.6%) smoked cannabis, 50 (47.2%) had poor sleeping habits, 29 (27.4%) had high stress levels, 37 (34.9%) had hypertension, and 22 (20.8%) had diabetes. Twenty (18.9%) patients had a family history of premature coronary artery disease. High and low high-density lipoprotein (HDL) levels were observed in 20 (18.9%) and 47 (44.3%) patients, respectively. The left anterior descending artery (LAD) was involved in 56% of the studied population associated with tramadol use. A significant association was found between both tramadol use and cannabis smoking and presence of heavy thrombus burden on coronary angiography., Conclusion: AMI in Egyptian youth was predominantly observed in men, with anterior STEMI as the most common presentation. Cannabis and tramadol addiction were high risk factors for AMI in Egyptian youth.

Sickle cell disease (SCD) is an autosomal recessive hemoglobinopathy characterized by increased cellular adhesiveness. Vaso-occlusion (VOC) is the most prevalent disease complication of SCD that could be altered by genetic factors. L-Selectin and integrin alpha 2 (ITGA2) are 2 adhesion molecules linked to vasculopathy and inflammation. The current study aimed at detecting the prevalence of genetic variants of L-selectin and ITGA2 as possible molecular modulators and novel therapeutic targets in a cohort of pediatric SCD patients. Genotyping was performed by polymerase chain reaction restriction fragment length polymorphism technique for 100 SCD patients and 100 age and gender-matched unrelated healthy controls. The homomutant genotype of ITGA2 C807T was significantly higher in SCD patients compared with controls (P=0.001) and confirmed almost a 3-fold increased risk of moderate and severe attacks of VOC. There are significant adverse effects caused by the polymorphisms of ITGA2, and hence Egyptian SCD patients could benefit from the targeted therapies specifically against ITGA2 to ameliorate the severe course of the disease and improve the quality of life. However, further studies of genotypes and expression levels of these adhesion molecules during the attacks of VOC are recommended.
