The Role of Angiotensin Converting Enzyme 1 Insertion/Deletion Genetic Polymorphism in the Risk and Severity of COVID-19 Infection

Background: Individuals infected with the COVID-19 virus present with different symptoms of varying severity. In addition, not all individuals are infected despite exposure. Risk factors such as age, sex, and comorbidities play a major role in this variability; however, genetics may also be important in driving the differences in the incidence and prognosis of the disease. An Insertion/Deletion (I/D) polymorphism in the ACE1 gene (rs1799752) may explain these genetic differences. The aims of this study were to determine the potential role of ACE1 I/D genetic polymorphism in the risk of contracting COVID-19 as well as predicting the severity of COVID-19 infection.Methods: Three-hundred and eighty-seven non-related Lebanese subjects, 155 controls and 232 cases, who presented to the American University of Beirut Medical Center (AUBMC) for COVID-19 PCR testing were recruited. Clinical data were collected via filling a questionnaire and accessing the medical records. Peripheral blood was withdrawn for DNA isolation, and genotyping performed with standard PCR followed by band visualization on agarose gel.Results: In our study population, previously described risk factors such as gender, age, and comorbidities were associated with increase in disease susceptibility and severity. ACE1 I was the least common allele, and there was a positive association between ACE1 I and the risk of contracting the COVID-19 disease. More specifically, the frequency of II genotype was significantly higher among cases when compared to controls (P = 0.035) with individuals with the II genotype having greater risk for contracting the COVID-19 disease: OR = 2.074, P = 0.048 in the multivariate analysis. As for disease severity, the DD genotype and D allele were associated with increased risk for developing severe symptoms (OR = 2.845, P = 0.026 and OR = 2.359, P = 0.014, respectively), and the DD genotype with necessitating hospitalization (OR = 2.307, P = 0.042). In parallel, D allele carriers showed a significantly increased risk for developing hypoxia: OR = 4.374, P = 0.045.Conclusion: We found a positive association between ACE1 I and the risk of contracting the COVID-19 disease, and between ACE1 D and a worse outcome of the COVID-19 infection. Therefore, genotyping for ACE1 I/D polymorphism could be used to assess risk and predict severity for better prognosis and management of the disease.

Physicians’ approach to end of life care: comparison of two tertiary care university hospitals in Lebanon

Background The care of terminally ill patients is fraught with ethical and medical dilemmas carried by healthcare professionals. The present study aims to explore the approaches of Lebanese attending physicians towards palliative care, end of life (EOL) care, and patient management in two tertiary care university hospitals with distinct medical culture. Methods Four hundred attending physicians from the American University of Beirut Medical Center (AUBMC) and Hotel Dieu de France (HDF) were recruited. Participants were Medical Doctors in direct contact with adult patients that could be subject to EOL situations providing relevant demographic, educational, religious as well as personal, medical or patient-centric data. Results The majority of physicians in both establishments were previously exposed to life-limiting decisions but remains uncomfortable with the decision to stop or limit resuscitation. However, physicians with an American training (AUBMC) were significantly more likely to exhibit readiness to initiate and discuss DNR with patients (p<0.0001). While the paternalistic medicinal approach was prevalent in both groups, physicians with a European training (HDF) more often excluded patient involvement based on family preference (p<0.0001) or to spare them from a traumatic situation (p=0.003). The majority of respondents reported that previous directives from the patient were fundamental to life-limiting decisions. However, the influence of patient and medical factors (e.g. culture, religion, life expectancy, age, socioeconomic status) was evidenced in the HDF group. Conclusion Early physician-initiated EOL discussions remain challenged in Lebanon. Paternalistic attitudes limit shared decision making and are most evident in European-trained physicians. Establishing a sound and effective framework providing legal, ethical and religious guidance is thus needed in Lebanon.

Amblyopia risk factors among pediatric patients in a hospital-based setting using photoscreening

Purpose The aim of our study was to determine the prevalence of amblyopia risk factors in children visiting the American University of Beirut Medical Center (AUBMC) using automated vision screening. Methods This was a hospital-based screening of 1102 children aged between 2 and 6 years. Vision screening was performed using PlusoptiX S12 over 2 years (2018–2020). The need for referral to a pediatric ophthalmologist was based on the amblyopia risk factors set forth by the American Association for Pediatric Ophthalmology and Strabismus. Referred patients underwent a comprehensive eye examination. Results A total of 1102 children were screened, 63 were referred for amblyopia risk factors (5.7%); 37/63 (59%) underwent comprehensive eye examination and 73% were prescribed glasses. Of the non-referred group of children, 6.35% had astigmatism, 6.25% were hyperopic and 3.27% were myopic. The refractive errors observed among the examined patients were distributed as follows: 41% astigmatism, 51% hyperopia, and 8% myopia; amblyopia was not detected. Refractive amblyopia risk factors were associated with the presence of systemic disorders. Bland-Altman plots showed most of the differences to be within limits of agreement. Conclusion Using an automated vision screener in a hospital-based cohort of children aged 2 to 6 years, the rate of refractive amblyopia risk factors was 5.7%. Hyperopia was the most commonly encountered refractive error and children with systemic disorders were at higher risk.

Translation of the Tonsil and Adenoid Health Status Instrument to the Arabic Language

Background: Adenotonsillectomy is one of the most commonly performed pediatric surgeries worldwide. To date, no questionnaire assessing the quality of life of patients post-operatively exists in the Arabic language. Our objective is to translate the Tonsil and Adenoid Health Status Instrument from English to Arabic and evaluate its internal consistency. We then attempt to use the translated questionnaire to assess the change in quality of life of patients undergoing adenotonsillectomy. Methods: Translation of the English TAHSI was performed using the guidelines for cross-cultural translation of quality of life measures. The obtained version of the questionnaire in Arabic was used on 141 patients enrolled prospectively over 3 years to assess for validity and internal consistency. Patients were enrolled from the pediatric otolaryngology clinic at the American University of Beirut Medical Center. Results: Cronbach alpha coefficients for the pre-operative and post-operative translated questionnaires were 0.79 and 0.78 respectively, confirming adequate internal consistency. Mean total pre-operative score was 28.88 ± 10.80, significantly higher than the mean post-operative score of 5.00 ± 5.57 (p<0.0001) showing an improvement in quality of life after surgery. Conclusion: In this study we successfully translated the Tonsil and Adenoid Health Status Instrument from English to Arabic. The questionnaire obtained is the only available quality of life measurement tool in Arabic specific to adenotonsillectomy. It was used to show that adenotonsillectomy significantly improves the quality of life of patients.

Patients’ and Family Members’ Views on Pacemaker Reuse: an International Survey

Introduction The reuse of cardiac implantable electronic devices may help increase access to these therapies in low- and middle-income countries (LMICs). No published data exist regarding the views of patients and family members in LMICs regarding this practice. Methods and Results A paper questionnaire eliciting attitudes regarding pacemaker reuse was administered to ambulatory adult patients and patients’ family members at outpatient clinics at Centro Nacional Cardiologia in Managua, Nicaragua, Indus Hospital in Karachi, Pakistan, Hospital Carlos Andrade Marín and Hospital Eugenio Espejo in Quito, Ecuador, and American University of Beirut Medical Center in Beirut, Lebanon. There were 945 responses (Nicaragua – 100; Pakistan – 493; Ecuador – 252; Lebanon – 100). A majority of respondents agreed or strongly agreed that they would be willing to accept a reused pacemaker if risks were similar to a new device (707, 75%), if there were a higher risk of device failure compared to a new device (584, 70%), or if there were a higher risk of infection compared to a new device (458, 56%). A large majority would be willing to donate their own pacemaker at the time of their death (884, 96%) or the device of a family member (805, 93%). Respondents who were unable to afford a new device were more likely to be willing to accept a reused device (79% vs. 63%, P<0.001). Conclusions Patients and their family members support the concept of pacemaker reuse for patients who cannot afford new devices.
