First trend analysis of antifungals consumption in Lebanon using the World Health Organization collaborating center for drug statistics methodology.

BACKGROUND: Antimicrobial resistance has reached an alarming rate globally, especially in middle-income countries such as Lebanon. The development of antifungal resistance is associated with the increased population's injudicious consumption. This study aims to measure antifungals consumption in Lebanon as a trend analysis of national data from 2004 to 2018. METHODS: This is a trend analysis of the consumption of antifungal agents in the Lebanese community. Data were obtained from the Intercontinental Marketing Statistics Database between 2004 and 2018. It measures the total consumptions per year, per drug, and the percentage of its correspondents for three routes of administration (oral, parenteral, and topical). Results were reported by Defined Daily Dose (DDD) per 1000 inhabitants per day and the total number of DDDs. RESULTS: Community consumption of antifungals in Lebanon has increased by approximately 18.64% between 2004 and 2018, as measured by the number of DDDs per 1000 inhabitants per day; and amplified by approximately 87.76% as measured by the number of DDDs. The highest consumption level was noted in 2017, with 1.52 DDDs/1000 inhabitants/day and 3,386,930 DDDs. Fluconazole was the most consumed antifungal while micafungin was the least with 6,723,869.2 (20.99%) and 48.5 (0.0002%) DDDs respectively. Topical antifungals ranked the first type consumed followed by oral and parenteral antifungals representing 51.72%, 48.24%, and 0.033% of the total consumption respectively. CONCLUSION: The findings from this study indicate a marked increase in antifungal consumption in the Lebanese community. This accelerates the need of implementing disease management guidelines and national antifungal stewardship. Moreover, these findings may be used in further benchmark utilization and antimicrobial resistance studies in Lebanon.

Effect of an educational intervention among Lebanese dentists on antibiotic prescribing: a randomized controlled study.

OBJECTIVES: To investigate whether an educational intervention could improve antibiotic prescribing among Lebanese dentists and assess antibiotic prescribing patterns regarding international guidelines. MATERIALS AND METHODS: An interventional randomized controlled trial was conducted from the first of April to the end of August 2017. This was an oral presentation of about 20 min based on a review of the literature and the international guidelines. Sixty dentists specializing in oral dental surgery or general practitioners participated in this study. All the patients who took a consultation over 2 months were involved. RESULTS: In this study, 950 antibiotic prescriptions were analyzed. A change was found only in antibiotics prescribed for tooth extraction and tooth extraction (impacted tooth). The intervention was impactful in raising the mean percentage of prescriptions compliant with indication and with the choice regarding antibiotics prescribed for prophylactic reasons. A dentist in the intervention group would have after the intervention period a mean percentage of prescriptions compliant with indication and with choice of 31.7% and 20.7%, respectively, above one in the control group. Despite the decrease in the overall number of antibiotics prescribed by dentists in the intervention group over time, this does not suggest that this was solely due to the effect of the intervention. CONCLUSION: This study highlights the importance of continuing medical education to optimize antibiotic use in dentistry. CLINICAL RELEVANCE: This study can serve as the basis for a future audit, training, and feedback intervention to increase dentists' awareness of recommended guidelines and optimal antibiotic use.

Determinants of ultrafine particles, black carbon, nitrogen dioxide, and carbon monoxide concentrations inside vehicles in the Paris area: PUF-TAXI study.

This study presents real-time concentrations of traffic-related air pollutants during 499 trips conducted by 50 Parisian taxi drivers from PUF-TAXI project. Ultrafine particles (UFP), black carbon (BC), and nitrogen dioxide (NO2 )/carbon monoxide (CO) were measured inside vehicles by Diffusion Size Classifier Miniature® , microAeth® , and Gas-Pro® , respectively, for nine hours. Vehicle/trip data characteristics were collected by questionnaires and on ambient conditions by monitoring stations. The associations between pollutant levels and their potential determinants were analyzed using generalized estimating equation model. Determinants of in-vehicle pollutants levels were identified: (1) ambient factors (meteorology and ambient pollution)-affecting BC, NO2, and CO; (2) vehicle characteristics-affecting all pollutants; and (3) trip-related driving habits-affecting UFP, BC, and CO. We highlight that commuters can, therefore, avoid high in-vehicle air pollutant concentrations mainly by (1) closing windows and activating air-conditioning under air recirculation mode in congested traffic; (2) smooth driving; and (3) maintaining cabin air filters.

Trend of antibiotic consumption and its association with influenza-like illnesses in France between 2004 and 2018.

BACKGROUND: Antibiotic consumption has been reported to be driven by the treatment of respiratory tract infections. Our objectives were to describe the trend of antibiotic consumption in France compared with that of other European countries; to describe the evolution of each antibiotic class in France; and to explore the relationship between antibiotic consumption and incidence of influenza-like illnesses. METHODS: In this observational study, antibiotic consumption was reported as defined daily doses per 1000 inhabitants per day in the community and hospital sectors in descriptive and graphical formats, using data from the European Surveillance of Antimicrobial Consumption Network database. The total consumption and the consumption of different classes of antibiotics in France according to time and influenza-like illnesses were studied using multiple linear regression models. RESULTS: The total consumption of antibiotics in France was constant over the 15 years. It was driven by the community sector (92.8%) and was higher than the consumption of other European Union countries (P-value < 0.001). The beta-lactam penicillins were the most consumed antibiotic class and the only class that increased with time. The multiple linear regression models showed a positive correlation between antibiotic consumption in the community sector and incidence of influenza-like illnesses [B = 0.170, 95% CI (0.088-0.252)]. Similar significant results were shown between other antibiotic classes used in the management of influenza-like illnesses (other beta-lactams, and macrolides, lincosamides and streptogramins) and influenza-like illnesses. CONCLUSION: Our results suggest that antibiotics used in the management of respiratory tract infections might be involved in the irrational use of antibiotics.

Determinants of knowledge and prevention measures towards COVID-19 pandemic among Lebanese dentists: a cross sectional survey.

BACKGROUND: Coronavirus Disease 2019 (COVID-19) is a major global threat. Healthcare professionals including dentists are facing real challenges during this pandemic. This study aimed to evaluate knowledge, attitudes, and prevention measures of Lebanese dentists towards COVID-19 and determinants of high level of knowledge and prevention practices. METHODS: A cross-sectional study was conducted between May and August 2020 in Lebanon on a random sample of 323 Lebanese dentists. Data were collected through an online survey questionnaire. A multivariate linear regression model was used to evaluate factors associated with COVID-19 knowledge. A multivariate logistic regression was conducted to evaluate the factors associated with high level of prevention measures towards COVID-19. RESULTS: The mean COVID-19 knowledge index was 24.5 over 38 with only 15% achieving high knowledge level. The mean prevention measures index was 11.4 over 16 with only 35% achieving high prevention level. Higher knowledge index was associated with younger age, being employed, and considering dentist's role significant in teaching others about COVID-19. General dental practitioners, dentists living with family members and concerned about their family members to get infected because of their occupational exposure were more likely to report higher level of adopted prevention measures. Higher knowledge was associated with high level of prevention measures. CONCLUSIONS: Given the rapid evolution of information related to COVID-19 pandemic, dentists should be regularly educated through trainings, workshops, and updates of national guidelines for dental healthcare.

Acceptance of COVID-19 vaccination and its determinants among Lebanese dentists: a cross-sectional study.

BACKGROUND: Dentists are at high risk of exposure to occupational Coronavirus Disease 2019 (COVID-19). Since vaccination is crucial to control COVID-19 pandemic, we aimed to assess COVID-19 vaccination acceptance and its determinants among Lebanese practicing dentists. METHODS: A cross-sectional online study was conducted between February 15 and 22, 2021, among dentists practicing in Lebanon. Prevalence of COVID-19 vaccine acceptance was estimated. A multivariable modified Poisson regression model was used to explore determinants of COVID-19 vaccine acceptance. RESULTS: In total, 86% of participants were willing to receive or have already received a COVID-19 vaccine. Having received the influenza vaccine during the COVID-19 pandemic was linked to a 12% increase in the COVID-19 vaccination acceptance rate. In addition, participants having moderate and high COVID-19 vaccination knowledge levels were more likely to accept receiving the vaccine, and participants whose fear of COVID-19 level was high were more likely to accept receiving the vaccine compared to those having a low fear level. Contrarily, those who visit the medical doctor only when needed and once a year were less likely to accept COVID-19 vaccine compared to participants who routinely visit the medical doctor. CONCLUSIONS: Our study showed a high level of acceptance of COVID-19 vaccination among Lebanese practicing dentists. And since knowledge about COVID-19 vaccination was associated with the vaccine acceptance, it should be improved and updated to further increase the acceptance rate. High acceptability of COVID-19 vaccination among dentists is expected to have a positive impact among the population in terms of increasing awareness and vaccine uptake.

Acute myeloid leukemia transformed to a targetable disease.

Acute myeloid leukemia (AML) is a heterogeneous neoplasm characterized by the monoclonal proliferation of immature progenitors. It is the most common acute leukemia in adults and its incidence increases with age. The standard traditional treatment in fit patients was the '3 + 7' regimen and cytarabine consolidation followed or not with allogeneic stem cell transplantation. Recently, several targeted therapies such as gemtuzumab ozogamicin targeting the CD33+ AML, midostaurin, gilteritinib and crenolanib inhibiting FLT3-positive AML and ivosidenib and enasidenib blocking IDH-mutated AML have been approved. These new drugs led to the change of the landscape of the treatment of AML and transforming this disease to a targetable one. We aimed in this paper to review the implications of each new target, the mechanisms of action of these new drugs and we discuss all the studies leading to the approval of these new drugs in their indications according to each target.

Cross-sectional study of in-vehicle exposure to ultrafine particles and black carbon inside Lebanese taxicabs.

Taxi drivers' exposure to traffic-related air pollutants inside their vehicles has been reported in different countries but not yet in Lebanon. Thus, we conducted a cross-sectional study on 20 Lebanese taxi drivers to (1) assess their exposure to ultrafine particles (UFP) and black carbon (BC) inside their vehicles and (2) identify determinants of this exposure. UFP and BC were measured using Diffusion Size Classifier Miniature® and microAeth® Model AE51, respectively, for 5 hours. Data on characteristics of vehicles and trips were collected by face-to-face interviews. Associations between pollutant levels and their determinants were analyzed by multiple linear regression. The mean of UFP count (35.2 ± 17.6 x 103 particles cm-3 ) and BC (5.2 ± 1.9 µg m-3 ) concentrations in-taxis was higher in the morning measurements compared with those in the afternoon measurements. UFP count increased in-taxis by 60% for every 10 minutes spent in blocked traffic and by 84% starting from two trips with smokers compared to trips without smokers. Conversely, UFP count decreased by 30% for every 10 minutes under both air-conditioning and air recirculation mode with windows closed. BC was not affected by any of these factors. Our findings suggest easy ways to reduce UFP exposure inside vehicles for all commuters.

Care and Discharge Outcome of Acute Stroke in Lebanon: A Hospital-Based Study.

The present study was conducted to assess stroke care and outcomes in two Lebanese hospitals. Patients admitted in 2012 and 2013 were retrospectively selected. Data were extracted from medical records for time to hospital arrival, stroke severity, management, and discharge outcomes. A Cox regression analysis was then conducted to predict time to in-hospital death. A total of 201 patients were included (mean age = 69.2 years), among whom 50% arrived within a delay of 3.75 hours. Half underwent brain imaging in the first hour, and nine patients received an acute intervention. Forty-four patients died at the hospital; 142 were discharged home, among whom 98 patients were dependent in their daily activities. Stroke severity on admission and time from onset to arrival were found to be significantly associated to the time to in-hospital death (adjusted hazard ratio [HRa] = 1.13 and HRa = 0.98 respectively; p < 0.05). The study sheds light on high case fatality and dependency rates at discharge among stroke patients in Lebanese hospitals.

How and when adjuvant treatment should be intensified in stage III colorectal cancers?

The adjuvant chemotherapy (FOLFOX) represents the standard of care in stage III colon cancer with some exceptions in old patients. Adjuvant treatment must also be discussed in high-risk stage II colon cancer. However, 40-50% of patients develop disease recurrence after curative R0 surgical resection. The liver was the most common site of recurrence followed by peritoneum. Although adjuvant chemotherapy improved disease-free survival and overall survival, 5-year overall survival remains less than 55% in stage III colon cancer. Different strategies could be adopted to escalate the standard adjuvant chemotherapy in these patients going from aggressive intravenous chemotherapy, hepatic arterial infusion chemotherapy, hyperthermic intraperitoneal chemotherapy to adding targeted therapies or immunotherapies. We reported in this review the published and ongoing trials evaluating these treatment modalities in colon cancer.

[Screening of diabetic retinopathy and maculopathy in Lebanese population using retinography and SD-OCT: The role of telemedicine]. / DÉPISTAGE de la RÉTINOPATHE et de la MACULOPATHIE DIABÉTIQUE au LIBAN par RÉTINOGRAPHIE et par SD-OCT: INTÉRÊT de la TÉLÉMÉDECINE.

PURPOSE: Diabetes and diabetic retinopathy (DR) are nowadays a major public health threat. The aim of this study is the screening of DR and diabetic maculopathy (DM) in a primary medical care center in Lebanon. We study also the interest of retinography and of SD-OCT in a telemedicine screening program. METHODS: This is a transversal study of patients with type 2 diabetes and with a regular follow-up in a primary medical care center in Beirut. For every patient, a retinography and an SD-OCT of the macula were obtained. Photos were sent by Internet to the Ophthalmology Department of Hôtel-Dieu de France to be evaluated by a retina specialist. Visual acuity and DR risk factors were assessed. RESULTS: 119 patients were included in this study. Mean age was 51.7 ± 10.2 years (54 females and 65 males). Mean diabetes duration was 12.15 years (SD 6:2). Mean of last three measurements of glycated hemoglobin was 8.1 ± 1.34%. Diabetic retinopathy was detected in 36 patients by retinography (30.3%). Diabetic maculopathy was confirmed by SD-OCT in 13 patients. Visual acuity was significantly correlated with central macular thickness. Mean diabetes duration, mean of last three measurements of glycated hemoglobin, peripheral neuropathy, positive macroalbuminuria and treatment with insulin were independently associated to diabetic retinopathy. CONCLUSION: Teleophthalmology is an efficient way for screening diabetic retinopathy in the Lebanese population. National screening program should be undertaken to adapt teleophthalmology on a larger scale.

Waterpipe effects on pulmonary function and cardiovascular indices: a comparison to cigarette smoking in real life situation.

INTRODUCTION: Smoking is known to have physiological effects on biological systems. The purpose of this study is to evaluate acute and chronic effects on pulmonary functions and cardiovascular indices of waterpipe (WP) smoking in real life circumstances. METHODS: Three groups were included in the study: non-smokers (N = 42), WP smokers (N = 42) and cigarette smokers (N = 48). A questionnaire was completed for each participant, in addition to pulmonary function [forced expiratory volume at 1 s (FEV1), 6 s (FEV6), percentage of FEV1/FEV6], and cardiovascular [diastolic blood pressure (DBP), systolic blood pressure (SBP) and heart rate (HR)] measures, taken before and after smoking. RESULTS: Mean values of FEV1, FEV6, FEV1/FEV6, DBP and SBP in WP and cigarette smokers were very close. However, WP smoking significantly increased HR compared to cigarette smokers (p = 0.007); duration of smoking, age at first WP and quantity of smoking affected pulmonary function and cardiovascular values. In the subgroup of WP smokers, DBP was acutely increased by a larger WP size (p = 0.011), while the FEV6 was acutely increased by a smaller WP size (p = 0.045). CONCLUSION: WP smoking affected the cardiovascular system more than cigarette smoking, while it had similar effects on pulmonary function.

SOPROLIFE system: an accurate diagnostic enhancer.

OBJECTIVES: The aim of this study was to evaluate a light-emitting diode fluorescence tool, the SOPROLIFE light-induced fluorescence evaluator, and compare it to the international caries detection and assessment system-II (ICDAS-II) in the detection of occlusal caries. METHODS: A total of 219 permanent posterior teeth in 21 subjects, with age ranging from 15 to 65 years, were examined. An intraclass correlation coefficient (ICC) was computed to assess the reliability between the two diagnostic methods. RESULTS: The results showed a high reliability between the two methods (ICC = 0.92; IC = 0.901-0.940; P < 0.001). The SOPROLIFE blue fluorescence mode had a high sensitivity (87%) and a high specificity (99%) when compared to ICDAS-II. CONCLUSION: Compared to the most used visual method in the diagnosis of occlusal caries lesions, the finding from this study suggests that SOPROLIFE can be used as a reproducible and reliable assessment tool. At a cut-off point, categorizing noncarious lesions and visual change in enamel, SOPROLIFE shows a high sensitivity and specificity. We can conclude that financially ICDAS is better than SOPROLIFE. However SOPROLIFE is easier for clinicians since it is a simple evaluation of images. Finally in terms of efficiency SOPROLIFE is not superior to ICDAS but tends to be equivalent with the same advantages.

The hidden dangers lurking at home: Unveiling the prevalence of leftover antibiotics and its associated factors among Lebanese households.

Background: Antimicrobial Resistance (AMR) is a major global concern. Irrational use of antibiotics including self-medication (SM) with leftovers without a medical prescription can be a leading cause. This study aimed to investigate the prevalence and related factors of leftover antibiotics (LA) in Lebanese households. Study design: A cross-sectional study of the Lebanese population was conducted between March and October 2022. Methods: Through random proportional stratified sampling, a total of 494 families participated in this study. Data collection was carried out through phone calls using a comprehensive and reviewed questionnaire. The data was then analyzed using SPSS version 26. Logistic regression was utilized to identify the factors associated with LA, with the presence of LA in households as the dependent variable and other factors such as age, region of residence, and presence of elderly individuals at home as the independent variables. Results: Among selected households, 118 households (23.89%) had LA. The most common type of antibiotic found was penicillin (59.84%). Most of the LA were in the form of tablets and capsules (94%) with valid expiration dates (87%). Antibiotics were mainly prescribed by doctors (61%), and the main reason for prescribing was acute respiratory tract infections (47.46%). SM was reported by 42.37% of the families with LA. A family with elderly patients (p = 0.002; OR = 2.23; 95% CI = 1.33-3.73) and those residing in Mount Lebanon (p = 0.019; OR = 2.28; 95% CI = 1.14-4.56) had significantly higher odds of having LA. Conclusion: Leftover antibiotics were found in nearly a quarter of the addressed Lebanese families. Therefore, public educational campaigns should be launched to limit injudicious antibiotic use including SM, and to promote proper disposal of any leftovers. It is also crucial to adopt the One Health approach by developing national programs for the safe disposal of LA and implementing regulations to restrict the distribution of antibiotics in pharmacies without a prescription.

Prevalence of medication administration errors in hospitalized adults: A systematic review and meta-analysis up to 2017 to explore sources of heterogeneity.

Previous estimates to meta-analyze administration error rates were limited by the high statistical heterogeneity, restricting their use. This study aimed to investigate sources of heterogeneity in pooled administration error rates in hospitalized adults. We systematically searched scientific databases up to November 2017 for studies presenting error rates/relevant numerical data in hospitalized adults. We conducted separate meta-analyses for the numerators: One Medication Error (OME) (each dose can be correct or incorrect) and Total Number of Errors (TNE) (more than one error per dose could be counted), using the generic inverse variance with a 95% confidence interval. Heterogeneity was assessed using the I2 and Cochran's Q test. We meta-analyzed 33 studies. The global pooled analyses based on the OME and TNE numerators showed very high heterogeneity (I2  = 100%; p < 0.00001). For each meta-analysis, subgroup analyses based on study characteristics (countries, wards, population, routes of administration, error detection methods, and medications) yielded results with consistently elevated heterogeneity. Beyond these characteristics, we stratified the studies according to the mean error prevalence level as the threshold. Based on the OME numerator, we identified two subgroups of low (0.15[0.13-0.17]; I2  = 0%; p = 0.43) and high (0.26[0.24-0.27]; I2  = 38%; p = 0.17) pooled prevalence rates, with controlled heterogeneity. Similarly, for the TNE numerator, we identified two subgroups of low (0.10[0.09-0.10]; I2  = 0%; p = 0.76) and high (0.28[0.27-0.29]; I2  = 0%; p = 0.89) pooled prevalence rates, with controlled heterogeneity. These subgroups differed regarding the denominators used: Total opportunities for errors versus others (doses, observations, administrations). Calculation methods, specifically the denominator, seem a primary factor in explaining heterogeneity in error rates. Standardizing numerators, denominators, and definitions is necessary.

Estimation of the influenza-associated respiratory hospitalization burden using sentinel surveillance data, Lebanon, 2015-2020.

Introduction: Influenza epidemics cause around 3 to 5 million cases of severe illness worldwide every year. Estimates are needed for a better understanding of the burden of disease especially in low- and middle-income countries. The objective of this study is to estimate the number and rate of influenza-associated respiratory hospitalizations in Lebanon during five influenza seasons (2015-2016 to 2019-2020) by age and province of residence in addition to estimating the influenza burden by level of severity. Methods: The severe acute respiratory infection sentinel surveillance system was used to compute influenza positivity from the influenza laboratory confirmed cases. The total of respiratory hospitalizations under the influenza and pneumonia diagnosis was retrieved from the Ministry of Public Health hospital billing database. Age-specific and province-specific frequencies and rates were estimated for each season. Rates per 100 000 population were calculated with 95% confidence levels. Results: The estimated seasonal average of influenza-associated hospital admission was 2866 for a rate of 48.1 (95% CI: 46.4-49.9) per 100 000. As for the distribution by age group, the highest rates were seen in the two age groups ≥65 years and 0-4 years whereas the lowest rate was for the age group 15-49 years. For the distribution by province of residence, the highest influenza-associated hospitalization rates were reported from the Bekaa-Baalback/Hermel provinces. Conclusion: This study shows the substantial burden of influenza in Lebanon mainly on high-risk groups (≥65 years and <5 years). It is crucial to translate these findings into policies and practices to reduce the burden and estimate the illness-related expenditure and indirect costs.

HPV Vaccination Prevalence among Lebanese Female University Students: A Cross-Sectional Study.

Background: Cervical cancer is the fourth most common cancer in women, worldwide. Most often, cervical cancer is caused by a human papillomavirus (HPV) infection. A lack of studies concerning HPV knowledge and vaccination among the Lebanese population is noticed. We aim to assess the prevalence of HPV vaccine administration among female university students in Lebanon alongside determining the predictors influencing vaccine uptake. Lastly, knowledge scores concerning HPV and HPV vaccination are also computed. Methods: This is a cross-sectional analytical study. It is an anonymous, online-based, close-ended questions survey conducted between the 24th of February 2021 and the 30th of March 2021. Our questionnaire was addressed to females aged between 17 and 30 years and enrolled in a Lebanese university. The collected data were analyzed using Statistical Package for Social Sciences (SPSS) v.26. We used bivariate analysis to compare the rate of vaccination with different variables. We used the chi-square test for categorical variables and Student's t-test for continuous variables. Logistic linear regression was conducted between the state of vaccination and other statistically significant variables from the bivariate analysis. Results: We have received a total of 454 questionnaires. Among the respondents, only 18.9% had received a minimum of one dose of the HPV vaccine. The mean age of up taking the first dose of the vaccine was 17.5 years. In addition, 48% of the respondents were not willing to take the HPV vaccine during the upcoming year. Barriers to not taking the HPV vaccine were mainly the low levels of knowledge concerning HPV and its vaccine. In the multivariate analysis, three predictors were found to affect the rate of HPV vaccination: university type, paternal educational level, and HPV vaccine knowledge score. In detail, a student enrolled in a public university had 77% likelihood of not being vaccinated. Furthermore, female students with a paternal educational level higher than a university degree had 88% probability of being vaccinated. Finally, every increase in the HPV vaccination knowledge of one point increased the likelihood of being vaccinated by 37%. Conclusion: A low vaccination rate among female university students in Lebanon was noticed in our study. In addition, a lack of HPV and HPV vaccine knowledge was found in our population. An awareness campaign alongside public vaccination programs is recommended in order to accomplish higher rates of HPV immunization.

Assessment of COVID-19 vaccines acceptance in the Lebanese population: a national cross-sectional study.

BACKGROUND: Vaccines have become the best weapon for epidemic prevention and control in the absence of standard approved effective therapies. However, skepticism about the vaccine efficacy and safety is constantly reported. To our knowledge, there has been no study assessing COVID-19 vaccine acceptance in Lebanon. The primary objective of this survey is to assess the COVID-19 vaccines' acceptance and its related determinants in the Lebanese population. METHODS: A cross-sectional study was conducted in Lebanon from February 16 through February 25, 2021. Data was collected using an online questionnaire via social media platforms using the snowball technique. The questionnaire consisted of 47 questions related to sociodemographic and medical history, COVID-19 experience, knowledge, practice, and beliefs towards COVID-19 vaccines, including vaccines acceptance. Binary logistic regression was performed to identify factors associated with vaccine acceptance. RESULTS: A total of 1209 questionnaires were completed; around 63.4% have reported their acceptance for receiving the COVID-19 vaccine, while only 57% of participants registered themselves on the national platform. The multivariable analysis showed that a higher knowledge scale, living in an urban residential area, having hypertension, not having a food allergy, reporting a higher fear to experience COVID-19 infection, and receiving or wanting to receive influenza vaccine, were positive predictors of COVID-19 vaccines acceptance. CONCLUSIONS: Our findings support the need to improve knowledge about COVID-19 infection and vaccination through education and awareness programs. Specifically residents of rural areas should be targeted to optimize COVID-19 vaccine acceptance among the Lebanese population.

An evaluation of prophylactic and therapeutic antibiotic prescribing in Lebanese dental practice.

OBJECTIVES: To evaluate antibiotic prescribing patterns and correlates among Lebanese dentists. METHODS: A descriptive observational study was conducted, from the first of April to the end of May 2017. Dentists who specialized in oral dental surgery or general dental practitioners were eligible to participate in this study. All patients who sought consultation with the selected dentists over a 1 month period were included. KEY FINDINGS: A total of 2323 oral and dental procedures were performed by 60 dentists; 553 antibiotic prescriptions were prescribed, representing 23.8% (52.35% for prophylactic purposes and 47.65% for curative purposes). Prophylactic indications were mainly for implant surgery (36.3%) with only 1% appropriate. Curative use was mainly for periodontal abscesses/abscesses (indeterminate) (22.8%), followed by pulpal diseases and periradicular complications (20.5%); it was appropriate in only 1.7 and 1.9% of cases respectively. Amoxicillin-clavulanic acid was the antibiotic that was mostly prescribed for both curative and prophylactic uses (57.6 and 55.9%, respectively), followed by amoxicillin for prophylactic purposes and a combination of spiramycin plus metronidazole for curative purposes. Adherence to guidelines was low for both curative and prophylactic purposes (17.4 and 21.8%, respectively), but was better in patients who were younger [adjusted odds ratio(aOR) = 0.96], male (aOR = 0.40), or had cardiac disease with moderate or high infective endocarditis risk (aOR = 21.72), and when prescribed by oral surgeons (aOR = 0.15). CONCLUSIONS: This study showed evidence of the overuse of antibiotics among Lebanese dentists. It can serve as a basis for future studies to optimize antibiotic use among dentists in Lebanon.

Patterns of Medication Errors Involving Older Adults Reported to the French Medication Error Guichet.

OBJECTIVES: The aims of the study were to describe medication errors (MEs) involving older adults reported to the French Medication Error Guichet and to compare them with MEs in younger adults, in each of the hospital and community settings. METHODS: Retrospective secondary data analysis of MEs reported throughout 2013 to 2017 was performed. Descriptive and multivariate analyses were performed to compare actual and potential ME reports between older adults (aged ≥60 y) and younger adults (aged ≥18, <60 y). RESULTS: We analyzed 4979 reports. In older adults, both in hospital (n = 1329) and community (n = 1264) settings, antithrombotic agents were frequently reported in MEs and were significantly more likely to be associated with reported MEs in older adults compared with younger adults. In hospital setting, antibacterials for systemic use (adjusted odds ratio [aOR] = 1.87, 95% confidence interval [CI] = 1.19-2.93) and antineoplastic agents (aOR = 2.22, 95% CI = 1.34-3.69), whereas in community setting, psycholeptics (aOR = 1.43, 95% CI = 1.04-1.98) and drugs used in diabetes (aOR = 6.01, 95% CI = 3.21-11.2) were more likely to be associated with reported MEs in older adults. In both settings, wrong dose and wrong drug were the most frequently reported error types in older adults; however, wrong technique error type (aOR = 2.06, 95% CI = 1.30-3.28) in hospital setting and wrong patient (aOR = 2.17, 95% CI = 1.30-3.60) in community setting were more likely to be associated with reported MEs in older adults. CONCLUSIONS: We identified specific ME patterns for older adults, including antithrombotic agents in both settings; antibacterials for systemic use, antineoplastic agents, and wrong technique in hospital setting; and psycholeptics, drugs used in diabetes, and wrong patient in community setting. These findings inform future studies investigating population-specific medication safety strategies.
