A cross-sectional study of knowledge, attitude, behaviour and preventive measures for COVID-19 infection in Lebanon

Background: The World Health Organization has often reiterated its recommendations for the prevention of COVID-19, however, the success of these measures largely depends on public knowledge and attitudes. Aims: This study assessed the relationship between knowledge, attitude, behaviour and preventive measures for COVID-19 infection in a Lebanese population. Methods: This cross-sectional study was conducted between September and October 2020 using the snowball sampling technique and an online self-administered questionnaire. The questionnaire had 4 parts targeting sociodemographic characteristics; medical history; knowledge, attitude and practices (preventive measures and behaviours related to COVID-19); and mental health variables such as psychological distress. Two models were derived using multivariable binomial logistic regression to optimize the picture of COVID-19 correlates. Results: Our sample comprised 1119 adults. Being older, female, a regular alcohol consumer, waterpipe smoker, having low level of education, low family income, and having contact with a COVID-19 patient correlated with increased odds of ever having been diagnosed with COVID-19. Participants who had ever been diagnosed with COVID-19 had a significantly better knowledge and a higher risky practice scale [adjusted odds ratio (ORa) = 1.49; 95% CI 1.27–1.74; P < 0.001; and ORa = 1.04; 95% CI 1.01–1.08; P = 0.024, respectively]. Conclusion: The most important predictors of COVID-19 infection appear to be generally well-known among the general population, however, their knowledge and adherence to preventive measures should be continuously re-evaluated. This study highlights the need for greater awareness to improve precautionary behaviours among the public.

Assessment of gender gap in surgical specialties among Lebanese medical personnel: the need for involvement of women in surgery

Background: Little is known about gender disparity in the surgery specialty in Lebanon. Aims: To assess the status of female surgeons and possible gender gaps in surgery specialty in Lebanon. Methods: The study was conducted in May 2021. Data were retrieved from the Lebanese Order of Physicians website, indicating the number of physicians in the different specialties, their gender, hospitals, and locations. The c2 test of homogeneity was used to establish whether the gender distribution was equal. Results: Women only accounted for 21.84% (3,370) of physicians in Lebanon, with surgery having the lowest number of female physicians in (n = 65; 2.30%). Women accounted for 1.63% of all surgeons in Lebanese hospitals, there were more female plastic and reconstructive surgeons (n = 12; 7.14%), while neurosurgery, oncological surgery and vascular surgery had no females. There was no significant difference in gender between academic and non-academic institutions (χ2 = 2.164, P = 0.149), or between public and private hospitals (χ2 = 1.277, P = 0.234). Conclusion: The surgical specialty had the widest gender gap among all the medical fields in Lebanon. Therefore, the healthcare systems, including public and private hospitals, have a long and difficult road in narrowing the gender gap. Different strategies to incorporate women into surgery should be explored to assure equitable opportunities for all physicians, based on competency rather than gender.

Living with chronic obstructive pulmonary disease in Lebanon: a phenomenological study

Background: Lebanon has the fastest growing older adult population in the Arab region but few social resources to address their needs. No studies have explored the experience of patients with chronic obstructive pulmonary disease (COPD) in Lebanon. Aims: Exploring the experiences of individuals living with COPD in Lebanon. Method: Using a descriptive phenomenological research design, qualitative individual semi-structured interviews were conducted with COPD patients living in Lebanon, between May 2019 and September 2019. Results: Fifty participants agreed to be interviewed. The majority were men (56%) and had moderate COPD (40%). Mean age was 71.5 (standard deviation 9.0) years. We found that COPD affects three dimensions of patients’ lives: educational, organizational and psychosocial. Conclusion: The results highlight the need for multidisciplinary strategies to address the needs of people with COPD in Lebanon, including their caregivers. Strategies include patient education and the development of new methods to facilitate and promote partnership between health care professionals, COPD patients and their caregivers.

Managing Endothelial Dysfunction in COVID-19: A Pilot, Double-Blind, Placebo-Controlled, Randomized Clinical Trial at the Lebanese American University Medical Center - Rizk Hospital (MEDIC-LAUMCRH)

BackgroundCoronavirus disease 2019 (Covid-19) is associated with endothelial dysfunction. Pharmacologically targeting the different mechanisms of endothelial dysfunction may improve clinical outcomes and lead to reduced morbidity and mortality MethodsIn this pilot, double-blind, placebo-controlled, randomized clinical trial we assigned patients who were admitted to the hospital with mild, moderate, or severe COVID-19 infection to receive, on top of optimal medical therapy, either an endothelial protocol consisting of (Nicorandil, L-arginine, Folate, Nebivolol, and Atorvastatin) or placebo for up to 14 days. The primary outcome was time to recovery, measured by an 8 category ordinal scale and defined by the time to being discharged from the hospital or hospitalized for infection-control or other nonmedical reasons. Secondary outcomes included the composite outcome of ICU admission or the need for mechanical ventilation, all-cause mortality, and the occurrence of side effects ResultsOf 42 randomized patients, 37 were included in the primary analysis. The mean age of the patients was 57 years; the mean BMI of study participants was 29.14. History of hypertension was present in 27% of the patients, obesity in 45%, and Diabetes Mellitus in 21.6%. The median(Interquartile range) time to recovery was not significantly different between the endothelial protocol group (6 [4-12] days) and the placebo group (6 [5-8]days)(p-value = 0.854). Furthermore, there were no statistically significant differences in the need for mechanical ventilation or ICU admission, all-cause mortality, and the occurrence of side effects between the endothelial protocol group and the placebo group. ConclusionAmong patients hospitalized with mild, moderate, or severe COVID-19 infection, targeting endothelial dysfunction by administering Nicorandil, L-arginine, Folate, Nebivolol, and Atorvastatin on top of optimal medical therapy did not decrease time to recovery. However, this treatment protocol was associated with an excellent safety profile. Adequately sized prospective randomized controlled trials are needed for the evaluation of the role of treating endothelial dysfunction in COVID-19 infection.

Effect of Screen Time on Physical and Mental Health and Eating Habits During COVID-19 Lockdown in Lebanon

Objective@#This study aimed to explore whether screen time and the screen type impacted various health aspects of children, including physical activity (PA), sleep quality, and eating habits. Additionally, we investigated whether children’s eating behavior while using electronic devices affects their physical and mental health. @*Methods@#We conducted an online survey asking for screen use (duration, type, and purpose), PA, eating habits, sleep problems, and level of depression. The participants were children between the ages of 3 and 7 years, and the survey was answered by the participants’ parents from March 3 to March 20, 2021. @*Results@#A screen time of ≥2 h in children was associated with various clinical characteristics, such as body mass index (BMI), sleep problems, depression, decreased PA, and unusual eating habits. Children’s food eating behavior while using electronic devices was predicted by a total screen time ≥2 h, smartphone screen time ≥2 h, sleep problems, owning electronic devices, and eating unhealthy food. @*Conclusion@#There was an interplay among children’s PAs, eating behaviors, depression, sleep problems, and screen time in this pandemic era. Therefore, guiding children on the correct use of electronic devices and helping them eat healthy are paramount during this COVID-19 pandemic.

The Preschool Asthma Risk Factors Scale: A predictive tool for asthma and respiratory symptoms among preschool children in Lebanon.

BACKGROUND: The Preschool Asthma Risk Factor Scale (PS-ARFS) is a tool that enables clinicians to assess environmental exposure of preschool children, history of parental asthma, and dietary habits. The objective of this study was to evaluate the PS-ARFS ability to predict asthma diagnosis and respiratory symptoms 1 year after baseline assessment and improve the scale if necessary. METHODS: A prospective cohort study conducted between November 2018 and March 2019 in three Lebanese schools (from three different Lebanese Governorates) enrolled 515 preschool children aged 3-5 years. Parents completed a detailed questionnaire sent with their children (Phase 1; T0). All parents who participated in Phase 1 were invited to take the same survey by telephone (Phase 2; T1), 1 year later. The interview was conducted by one study-independent person. Of the total sample, 141 (27.4%) children were lost to follow-up. RESULTS: Higher odds of asthma diagnosis at 1 year were significantly associated with playing outside (adjusted odds ratio [aOR] = 3.958) and having a heating system in the bedroom (aOR = 6.986) at baseline, but inversely associated with the female gender (aOR = 0.365). Based on those results, the improved PS-ARFS-I was generated. A higher PS-ARFS-I at T0 was significantly associated with higher odds of asthma at T1 (aOR = 1.08; p < 0.001; 95% confidence interval [CI] 1.05-1.10); similar results were obtained with the longer PS-ARFS (aOR = 1.079; p < 0.001; 95% CI 1.050-1.109). Moreover, among non-asthmatic children at baseline, the PS-ARFS score predicted wheezing and cough at T1 but not bronchial secretions; the PS-ARFS-I score at baseline did not predict symptoms at T1. CONCLUSION: This study shows that the PS-ARFS-I and PS-ARFS could predict diagnosed asthma at 1-year follow-up. The PS-ARFS predicted respiratory symptoms (wheezing and cough) after 1 year among non-asthmatic children at baseline, suggesting that a score based on risk factors, measured early on, can predict better later symptoms and disease.

Combined Anticoagulant and antiplatelet therapy is associated with an improved outcome in hospitalized COVID-19 patients: a propensity matched cohort study

BackgroundCOVID-19 is a respiratory disease that results in a prothrombotic state manifesting as thrombotic, microthrombotic and thromboembolic events. As a result, several antithrombotic modalities have been implicated in the treatment of this disease. This study aimed to identify if therapeutic anticoagulation or concurrent use of antiplatelet and anticoagulants was associated with an improved outcome in this patient population. MethodsA retrospective observational cohort study of adult patients admitted to a single university hospital for COVID-19 infection was performed. The primary outcome was a composite of in-hospital mortality, ICU admission, or the need for mechanical ventilation. The secondary outcomes were each of the components of the primary outcome, in-hospital mortality, ICU admission, or the need for mechanical ventilation. Results242 patients were included in the study and divided into 4 subgroups: therapeutic anticoagulation (TAC), prophylactic anticoagulation + antiplatelet (PACAP), therapeutic anticoagulation + antiplatelet (TACAP), and prophylactic anticoagulation (PAC) which was the reference for comparison. Multivariable cox regression analysis and propensity matching were done and showed when compared to PAC, TACAP and TAC were associated with less in-hospital all cause mortality with an adjusted hazard ratio (aHR) of 0.113 (95% confidence interval (CI) 0.028-0.449) and 0.126 (95% CI, 0.028-0.528) respectively. The number needed to treat (NNT) in both subgroups was 11. Furthermore, PACAP was associated with a reduced risk of invasive mechanical ventilation with an aHR of 0.07 (95% CI, 0.014-0.351). However, the was no statistically significant difference in the occurrence of major or minor bleeds, ICU admission, or the composite outcome of in-hospital mortality, ICU admission or the need for mechanical ventilation. ConclusionThe use of combined anticoagulant and antiplatelet agents or therapeutic anticoagulation alone in hospitalized COVID-19 patients was associated with a better outcome in comparison to prophylactic anticoagulation alone without an increase in the risk of major and minor bleeds. Sufficiently powered randomized controlled trials are needed to further evaluate the safety and efficacy of combining antiplatelet and anticoagulants agents or using therapeutic anticoagulation in the management of patients with COVID-19 infection. What is already known about this subject ?Covid-19 infection is associated with several complex coagulation disorders resulting in thrombotic, microthrombotic and thromboembolic events. Currently, prophylactic dose anticoagulation is considered the standard of care antithrombotic regimen in hospitalized COVID-19 patients. However, high-quality data about the subject is unavailable. What does this study add?This is the first adequately sized study in the literature to dwell on the antithrombotic strategy consisting of combination anticoagulant and antiplatelet therapy in the treatment of COVID-19 induced hypercoagulable state. Furthermore, it also challenges the currently recommended prophylactic dosing of anticoagulation used in the treatment of those patients. How might this impact on clinical practice?Our data suggests for the first time that concurrent use of anticoagulant and antiplatelet therapy is associated with a superior clinical outcome as compared to prophylactic anticoagulation used alone. Furthermore, it solidifies the emerging evidence that therapeutic anticoagulation is linked to better clinical results than prophylactic anticoagulation.

Smartphone Screen Time Among University Students in Lebanon and Its Association With Insomnia, Bedtime Procrastination, and Body Mass Index During the COVID-19 Pandemic: A Cross-Sectional Study

Objective@#We aimed to investigate the association of increased smartphone screen time with insomnia, bedtime procrastination, depression, anxiety, body mass index (BMI), and physical activity during the coronavirus disease of 2019 (COVID-19) pandemic. @*Methods@#An online survey was performed for university students from all regions of Lebanon during the lockdown. The survey included questionnaires about smartphone screen time, diet, physical activity, psychological symptoms, and bedtime procrastination. We defined 6 hours of smartphone use as critical based on a survey done in United States. @*Results@#Among female students, smartphone use duration, physical activity levels, BMI, depression, anxiety, and insomnia severity were significantly higher than in male. When we stratified participants based on 6 hours of smartphone use, females, unhealthy food consumption, insomnia, anxiety, depression, and bedtime procrastination were significantly higher in the group with ≥6 hours of smartphone use. When we divided based on 7 hours, physical activity and body weight also differed between the two groups. Logistic regression analysis revealed that female, overweight, insomnia, and bedtime procrastination were significant predictors of a phone screen time of 7 hours. @*Conclusion@#Our findings suggest that adults should be more cautious and responsible when using smartphones and be more concerned about the health-related risks.

Cigarette and waterpipe smoking decrease respiratory quality of life in adults: results from a national cross-sectional study.

Background. Chronic obstructive pulmonary disease (COPD) is gaining an importance over the world, and its effect on quality of life is better grasped. Our objective was to use the Clinical COPD Questionnaire (CCQ) to describe the respiratory quality of life in the Lebanese population, stressing on differences between smokers and nonsmokers. Methods. Using data from a cross-sectional national study, we checked the construct validity and reliability of the CCQ. Factors and items correlation with postbronchodilator FEV1/FVC were reported, in addition to factors and scale association with COPD and its severity. We then conducted a multiple regression to find predictors of quality of life. Results. The CCQ demonstrated excellent psychometric properties, with adequacy to the sample and high consistency. Smokers had a decreased respiratory quality of life versus nonsmokers, independently of their respiratory disease status and severity. This finding was confirmed in COPD individuals, where several environmental factors, lower education, and cumulative smoking of cigarette and of waterpipe were found to be independent predictors of a lower quality of life, after adjusting for COPD severity. Conclusions. Smoking decreases the respiratory quality of life of Lebanese adults; this issue has to be further emphasized during smoking cessation and patients' education.
