RESUMEN
BACKGROUND: Given the sparse data on the renin-angiotensin system (RAS) and its biological effector molecules ACE1 and ACE2 in pediatric COVID-19 cases, we investigated whether the ACE1 insertion/deletion (I/D) polymorphism could be a genetic marker for susceptibility to COVID-19 in Egyptian children and adolescents. METHODS: This was a case-control study included four hundred sixty patients diagnosed with COVID-19, and 460 well-matched healthy control children and adolescents. The I/D polymorphism (rs1799752) in the ACE1 gene was genotyped by polymerase chain reaction (PCR), meanwhile the ACE serum concentrations were assessed by ELISA. RESULTS: The ACE1 D/D genotype and Deletion allele were significantly more represented in patients with COVID-19 compared to the control group (55% vs. 28%; OR = 2.4; [95% CI: 1.46-3.95]; for the DD genotype; P = 0.002) and (68% vs. 52.5%; OR: 1.93; [95% CI: 1.49-2.5] for the D allele; P = 0.032). The presence of ACE1 D/D genotype was an independent risk factor for severe COVID-19 among studied patients (adjusted OR: 2.6; [95% CI: 1.6-9.7]; P < 0.001. CONCLUSIONS: The ACE1 insertion/deletion polymorphism may confer susceptibility to SARS-CoV-2 infection in Egyptian children and adolescents. IMPACT: Recent studies suggested a crucial role of renin-angiotensin system and its biological effector molecules ACE1 and ACE2 in the pathogenesis and progression of COVID-19. To our knowledge, ours is the first study to investigate the association of ACE1 I/D polymorphism and susceptibility to COVID-19 in Caucasian children and adolescents. The presence of the ACE1 D/D genotype or ACE1 Deletion allele may confer susceptibility to SARS-CoV-2 infection and being associated with higher ACE serum levels; may constitute independent risk factors for severe COVID-19. The ACE1 I/D genotyping help design further clinical trials reconsidering RAS-pathway antagonists to achieve more efficient targeted therapies.
RESUMEN
This study aimed to assess the perceptions of staff working at the University of Jeddah (UJ) Medical Center on the possibility of finding new financing methods for the administration and privatization of the primary and specialized medical care services it provides. A questionnaire link was sent online targeting all staff at the UJ Medical Center (n = 141). The questionnaire comprised 17 items under the following sections: demographic information, staff perceptions about the current status of the services provided by the UJ Medical Center and the possibility of finding new financing methods and additional sources of revenue for the administration. Of the 101 questionnaires returned, the majority were filled by males (n = 71; 70.3%). One-third of the participants (n = 39; 38.6%) have between 5 and 9 years of working experience in Medical Administration, and most of them (n = 42; 41.6%) reported that they have a background in the concept of revenue development/privatization/self-resources/paid treatment. Most were satisfied with the current status of the services provided (average rating = 3.39/5). However, most participants (n = 72; 71.3%) reported that the UJ Medical Center is not ready for the Revenue Development Project of privatization. The survey respondents demonstrated satisfaction with the medical services provided by the UJ Medical Center and the potential application of the Revenue Development Project. However, streamlining the privatization process according to the governmental structures is crucial for it to be implemented properly at the UJ Medical Center.
