•Cerebral vasospasm contributes to morbidity in subarachnoid hemorrhage.•Identifying genomics predicting risk of vasospasm offers novel therapeutic avenues.•Hp-2 allele was found to be an independent predictor of cerebral vasospasm. This study aims to investigate the genetic predisposition of haptoglobin (Hp) genotype as a predictor for cerebral vasospasm (CV) after acute subarachnoid hemorrhage (aSAH) in the Egyptian population. This permits CV risk factors stratification of patients with aSAH. Hence, it will guide the treatment plan and intensive monitoring for those patients. The study was carried out at El Matareya Teaching Hospital, Cairo, Egypt. We studied 50 patients with aSAH who were prospectively recruited and followed up by transcranial Doppler (TCD) examination for 14 days following aneurysmal rupture to early detect hemodynamic changes associated with CV and also the occurrence of delayed cerebral ischemia (DCI) as a secondary outcome. In this study, we attempted to analyze Hp genotyping as a potential predictor of CV and DCI during the acute phase of aneurysmal SAH. As a part of result analyses, among studied patients, 34 patients (68 %) developed CV and 19 patients (38 %) developed DCI. Only history of hypertension [RR = 1.6 (OR = 4)], diabetes mellitus [RR = 1.5 (OR = 3.4)] and smoking [RR = 1.5 (OR = 3.6)] had a significant independent relationship (P < 0.05) with short term risk to develop CV following aSAH. While, Age, sex, hyperlipidemia, cardiovascular disease and peripheral vascular disease, intracranial aneurysm site and size did not achieve significant association for developing CV. Regarding the poor Fisher scale and poor Hunt and Hess score both showed significant association with CV (P < 0.05). Genotyping of Hp protein among our study cohort revealed that the relative distribution of the three haptoglobin genotypes (Hp1−1, HP2-I & HP2−2) among Egyptian patients of aSAH was 14 %, 40 % and 46 %, respectively; (gene proportion being 0.34 for Hp1 and 0.66 for Hp2). Furthermore; Hp 2 allele was associated with radiographic vasospasm detected by TCD among the studied patients (2−2 & 2−1 Vs 1−1: RR = 5.4, OR = 19.8, P < 0.001). In the regression model; Hp genotype expressing Hp-2 allele is predictive for higher risk of development of CV after aSAH. Moreover, searching for the relationship between CV & Hp genotype and the risk for development of DCI; both variables failed to achieve a significant relationship for DCI (P > 0.05). The Hp genotype may determine the susceptibility to cerebral vasospasm after acute aSAH. This has the potential for use in risk stratification by allowing for the identification of those patients requiring intensive monitoring due to their inherent genetic risk for developing CV allowing for the promising selective application of aggressive treatments to those patients.

Background Medical students are the future doctors and play an essential role in the management of health issues. Their understanding of Alzheimer's disease (AD) is not only required but also necessary to provide the best possible care to patients. The present study aimed to assess medical students' knowledge about AD within the context of the recent reform of the Egyptian medical educational system, which switched to competency-based instead of outcome-based education since 2017. Methods A descriptive cross-sectional study was conducted among medical students in public and private Egyptian medical schools. Between August and November 2024, an anonymous self-administered questionnaire was uploaded to Google Forms and distributed online through commonly used social media platforms. The Alzheimer's Disease Knowledge Scale (ADKS), a validated and reliable tool, was used for the measurement of AD-related knowledge. Univariate and multivariable logistic regression models were used to determine the factors associated with having good or poor knowledge about AD among participants. Results In total, 1100 medical students were included through convenience and snowball sampling methods; their mean age was 20.9 ± 1.9 years, 55.5% were males, 59.6% were in their clinical years, and 15.6% had a positive family history of AD. The students' mean knowledge score was 19.10 ± 2.96 out of 30, representing 63.7% of answers correct, with a range of scores between 9 and 29. About 70.8% of the sample had good knowledge. The highest percentage of correct answers was for the treatment and management domain (76.5%), while the lowest percentage was for the caregiving domain (52.2%). Predictors of good knowledge were females [adjusted odds ratio (aOR) = 1.33 (95% confidence interval (CI): 1.01–1.76, p  = 0.043], attending a public university [aOR = 1.62 (95% CI: 1.09–2.41), p  = 0.015), clinical year students [aOR = 1.53 (95% CI: 1.07–2.16), p  = 0.018], living in an urban area [(aOR = 1.67 (95% CI: 1.23–2.25), p  < 0.001], and having higher family monthly income [aOR = 1.75 (95% CI: 1.13–2.72), p  = 0.012]. Conclusions The study highlights gaps in Egyptian medical students' knowledge of AD. Knowledge gaps were found in domains of caregiving and risk factors, urging educators and policymakers to enhance curricula, particularly preclinical curricula, with a specific focus on some socio-economic determinants.

Especially in the Saudi healthcare industry, pharmaceutical care services are essential to raising the standard of medical treatment. Better patient outcomes and more efficient healthcare delivery can result from incorporating pharmaceutical care as the nation's healthcare system develops. Pharmaceutical care services prioritize patient-centered strategies that enhance the overall healthcare experience in addition to drug management, claim Alshammari et al. (2020). Addressing the particular health issues that the Saudi populace faces, such as chronic illnesses and problems with medications, requires this integration.
