RESUMEN

BACKGROUND Recently, new therapeutic approaches have revolutionized the management of left ventricular dysfunction (LVD) and valvular heart disease (VHD), which are a growing public health problem. In parallel, there are no available epidemiological data about LVD and VHD in developing countries, especially in the Mediterranean area. This retrospective study was conducted at a single center and aimed to evaluate the associations between mitral and aortic valvular disease and left ventricle systolic and diastolic dysfunction in the Lebanese population. MATERIAL AND METHODS A retrospective study was conducted of 4520 consecutive patients aged >18 years who were referred to the Cardiovascular Department of Notre Dame de Secours-University Hospital in Jbeil-Lebanon for transthoracic echocardiography between December 2016 and December 2019. The study population was divided into different groups based on types of LVD and VHD. Left ventricle systolic dysfunction was defined as a left ventricle ejection fraction (EF) ≤40%. Statistical analysis was carried out using SPSS software version 20. RESULTS VHD and systolic dysfunction were more common in men, whereas diastolic dysfunction was more common in women. Being older than age 65 years and smoking were significantly associated with heart failure with preserved EF, whereas female sex was a significant preventive factor against heart failure with reduced EF. Systemic hypertension was correlated with mitral stenosis and tricuspid regurgitation, whereas diabetes mellitus was associated with tricuspid regurgitation (TR). Smoking and older age also appeared to be associated with aortic stenosis. CONCLUSIONS Mitral valve disease (regurgitation and stenosis) was significantly correlated with systolic dysfunction, whereas aortic and mitral regurgitation were associated with diastolic dysfunction. Better monitoring of cardiovascular disease risk factors may lead to a reduced burden of LVD and VHD.

RESUMEN

Among the various species of vegetation, conifers play an important role as a biomonitor of air pollution. The current study presents the determination of pesticides and polycyclic aromatic hydrocarbons in 15 conifer samples collected in August 2018 (summer season) from different regions in north Lebanon (Tripoli, Koura, Bcharre, and Akkar). Pollutants were extracted based on QuEChERS-SPME followed by liquid and gas chromatography-tandem mass spectrometry. Results showed that the samples collected from Bcharre region had the lowest concentration in both pesticides and polycyclic aromatic hydrocarbons with a total concentration of 50 and 66 ng g-1, while the samples collected from the regions widely known by their agriculture (Akkar, Tripoli, and Koura areas) were the most polluted with concentrations of 231 and 422 ng g-1, 192 and 370 ng g-1, and 127 and 98 ng g-1 for pesticides and polycyclic aromatic hydrocarbons respectively. This study revealed that conifers are suggested to be efficient biomonitors of contamination levels in the air.

RESUMEN

BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic led to a worldwide medical crisis, affecting mostly immunocompromised patients, such as cancer patients. Various cancer societies have issued recommendations regarding patients care, but few studies addressed the perception of cancer patients regarding this pandemic. OBJECTIVE: The aim of the study was to assess the perception of cancer patients regarding their health risks during this pandemic and the preventive measures taken. MATERIALS AND METHODS: An anonymous survey was conducted among cancer patients presenting for their treatment, during 10 consecutive working days, at the one-day clinic of Hotel-Dieu de France University hospital in Beirut. We evaluated their state of disease, comorbidities, precautions taken, and their concerns regarding the virus spread. RESULTS: A total of 216 patients responded with a mean age of 60 years. The majority had a good performance status (performance status = 0-1 in 79.6%), 51.4% had metastatic disease, and chemotherapy was the main therapy used (65.7%). A total of 52.3% of patients considered themselves to be at increased risk of contracting the virus. A total of 55.1% were more worried about the coronavirus rather than their disease. The priority was for the treatment of their cancer in 47.7% of the total patients studied. Of note, only 2.8% of planned one-day clinic reservations were canceled or postponed to avoid COVID-19 exposure. CONCLUSIONS: Although cancer is a disease with a high mortality rate, many patients are more concerned about the actual pandemic rather than their disease. Nevertheless, the absenteeism from their treatment sessions during the COVID-19 atmosphere was minimal.

RESUMEN

BACKGROUND: Relationship between emotional intelligence and emotional variables such as stress, depression, anxiety and mental health has been well documented in child and adult samples. New insights into the association between emotional intelligence and different components of mental health in one study (cognitive, emotional and behavioral dimensions) can help patients, therapists, relatives, and friends to understand, explain, and cope with symptoms. There have been no studies assessing the association between the emotional intelligence (EI) with various factors in Lebanon. This study principal aim was to evaluate how EI is related to mental health issues: social anxiety, depression, alcohol use disorders (AUD), work fatigue, stress and alexithymia in Lebanon. METHODS: 789 participants were enrolled in a cross-sectional study between November 2017 and March 2018. A cluster analysis was used to evaluate participants' profiles with the help of emotional intelligence subscales, to separate the Lebanese population into equal limited units with different characteristics using the K-mean technique. RESULTS: Three clusters were computed dividing participants into low EI (cluster 1; 24.5%), moderate EI (cluster 2; 43.7%) and high EI (cluster 3; 31.7%) respectively. Fitting into the cluster 1 (low EI) was significantly associated with higher AUD, alexithymia, anxiety, depression, perceived stress, social phobia, emotional, mental and physical work fatigue, suicidal ideation compared to cluster 3 (high EI). Fitting into the cluster 2 (moderate EI) was significantly correlated with higher AUD, depression, alexithymia, anxiety, perceived stress, social phobia, mental work fatigue and suicidal ideation compared to cluster 3 (high EI). CONCLUSION: This study results suggest that emotional intelligence is related to different variables, warranting interventions to limit/decrease alcohol abuse and mental/psychological illnesses as much possible.

RESUMEN

This study examines the risks of seawater intrusion (SWI) in data scarce aquifers along the Eastern Mediterranean by quantifying the interaction of the main natural, anthropogenic and climatic drivers, while also considering varying abilities of implementing adaptation and mitigation measures. For this purpose, we conducted a semi-quantitative Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis representing a first attempt at integrating a complex physical process with multi layered influences in a SWOT analysis model that was tested at 26 coastal aquifers with varying levels of SWI severity. The analysis results showed alarming signs of SWI at several eastern and southeastern aquifers, particularly those underlying densely populated centers (i.e. Beirut, Lebanon; Magoza, Cyprus; Gaza, Palestine and the Nile Delta, Egypt). The analysis also highlighted adaptive capabilities that appear to be strong in Cyprus, Israel and Turkey, emerging in Egypt, and weak in Lebanon, Syria, and Palestine. The risks exhibited a strong and statistically significant positive relationship with the reported status of SWI at the tested aquifers thus providing an effective decision-making tool towards the preliminary assessment of SWI in regions with data scarcity. The study concludes with proposing a framework for sustainable aquifer management in the East Med region with emphasis on controlling SWI risks.

RESUMEN

BACKGROUND: This study was conducted for several reasons, primarily because of the lack of an Arabic version of the HSCT that could be beneficial in our clinical practice. Another reason is the need to find potential relationships between various factors with executive functions, especially problematic mobile phone use as suggested by many previous studies, since smartphones have become, nowadays, a daily companion of people from all generations. Thus, it is important to conduct this study in Lebanon to be adapted to the ideas, customs and social behavior of the Lebanese citizens. Hence, the objectives of the current study are to use the Arabic version of the HSCT in healthy community-dwelling Arabic-speaking adults in Lebanon, to check its validity compared to other versions of the test, as well as to identify risk factors that might affect the executive functions in these adults. METHODS: Between August-December 2019, 350 participants were randomly selected. The Arabic version of the HSCT, divided into automatic and inhibition conditions, was used; in each condition, participants' response-time and number of errors committed were recorded. RESULTS: None of the scale items was removed. For the automatic condition, response-time items converged over one factor (αCronbach = 0.905) and number of errors converged over seven factors (αCronbach = 0.334). For the inhibition condition, response-time converged over one factor (αCronbach = 0.943) and number of errors converged over four factors (αCronbach = 0.728). Using electricity as a heating method inside the house was significantly associated with a lower response-time, whereas higher problematic mobile phone use was associated with higher response-time. Using wood as a heating system inside the house and higher problematic mobile phone use were associated with higher number of errors, while using Arabian incense (bakhour) inside the house was associated with lower number of errors. CONCLUSION: We were able to set normative data for the HSCT Arabic version for use in the Lebanese population. Problematic mobile phone use was associated with lower inhibitory control in terms of response-time and errors number.

RESUMEN

Aim: To describe the activity in the 'breast unit' at the department of radiology during the COVID-19 lockdown in a university hospital treating COVID-19 patients in a Middle-Eastern developing country. Materials: This was a retrospective study conducted from March 9 until 11 May 2020, in the breast unit at the department of radiology of a central university hospital in a Middle-Eastern developing country. Data were collected from 205 patients visiting the breast unit during the lockdown period and compared with the activity in the same period in the previous year. Results: Reduction of the breast unit activity was estimated at 73%. In addition, 153 mammograms, 205 ultrasounds, and 16 breast MRIs were done. Indications for mammogram were screening (41.5%), follow-up (22%), clinical symptoms (20%) and breast cancer surveillance (16.5%). MRI was performed mostly for preoperative surgical management. The rate of positive biopsies was 41%. All staff members and patients have accommodated to new adjustments. Conclusion: Activity in the breast unit dropped during the lockdown period. Staff should continue to seek their own and their patient's safety without diminishing the quality of healthcare.

RESUMEN

BACKGROUND: Coronavirus Disease (COVID-19) epidemic is a public health emergency of international concern. Dentists are exposed to the enormous risk of COVID-19 infection during this epidemic. This study aims to assess the knowledge and practice of dentists toward the COVID-19 epidemic in Lebanon. METHODS: We conducted an online survey using the snowball-sampling technique. Information on socio-demographic data, knowledge, practice, and additional information required concerning COVID-19 were collected. RESULTS: Our results showed that the majority of the Lebanese dentists had good knowledge (91.3%), and nearly half of the respondents had a good practice (58.7%) regarding COVID-19. The most common information source was the World Health Organization (73.7%). Multiple linear regression showed that specialist dentists who completed training on COVID-19 with a high level of knowledge had better practice. CONCLUSIONS: Lebanese dentists revealed good knowledge regarding COVID-19. However, dentists had limited comprehension of the extra precautionary measures that protect the dental staff and patients from this virus. Our findings have important implications for the development of strategies suitable for improving the level of practice among dentists and enhance prevention programs.

RESUMEN

Background: Oral health of the elderly is a major public health challenge. Data on oral health and dental care of the institutionalized elderly is lacking in Lebanon. Aims: (1) Assess the oral health of Lebanese people aged 65 years and over living in residential facilities; and (2) identify factors associated with poor oral status. Materials and Methods: A.sample of 526 nursing home residents aged 65 years and older was randomly selected from 46 residential facilities. Information collected were sociodemographic characteristics, degree of autonomy regarding toilet use and nutrition, presence of chronic diseases and medications, dry mouth sensation, dental brushing, access to oral health and reasons of dental visits. A structured oral examination was conducted to gather data on DMFT index, oral hygiene indices modified gingival index, and the unmet need for prosthesis. Statistical methods included bivariate and multivariate analyses. Results: 55.9% of the participants were edentates, 41.4% used partial and/or complete dentures, and the minority used dentures with good hygiene. 15% of the dentate sample reported regular tooth brushing, 7% reported to have visited the dental office in the past 12 months, and 57% presented an unmet need for prosthesis. Oral health status was significantly related to age, smoking, daily tooth brushing, and autonomy (P < 0.05). Subjects with chronic diseases and consuming medications were more likely to have xerostomia. Conclusion: Oral health status is poor in the elderly institutionalized Lebanese population, which should promote a multidisciplinary team sharing responsibility for daily oral hygiene and access to dental treatment.

RESUMEN

We explore the spread of the Coronavirus disease 2019 (COVID-19) in Lebanon by adopting two different approaches: the STEIR model, which is a modified SEIR model accounting for the effect of travel, and a repeated iterations model. We fit available daily data since the first diagnosed case until the end of June 2020 and we forecast possible scenarios of contagion associated with different levels of social distancing measures and travel inflows. We determine the initial reproductive transmission rate in Lebanon and all subsequent dynamics. In the repeated iterations (RI) model we iterate the available data of currently infected people to forecast future infections under several possible scenarios of contagion. In both models, our results suggest that tougher mitigation measures would slow down the spread of the disease. On the other hand, the current relaxation of measures and partial resumption of international flights, as the STEIR reveals, would trigger a second outbreak of infections, with severity depending on the extent of relaxation. We recommend strong institutional and public commitment to mitigation measures to avoid uncontrolled spread.

RESUMEN

Here we present a description of a new aphid species-Uroleucon (Uroleucon) lebanonense sp. nov. associated with Tragopogon coloratus (Asteraceae) in Lebanon. Apterous and alate viviparous females of the new species are described and illustrated, and compared with the morphologically similar species Uroleucon (U.) mongolicum Holman, 1975. An identification key to Palaearctic Uroleucon species with three setae on the first tarsal segment is provided. On the basis of the re-examination of the type material, we propose to restore the valid species status of U. (U.) altaicum Szelegiewicz, 1982 bona species which was regarded as a synonym of U. mulgedii (Nevsky, 1928). Additionally, we propose transfer of U. (U.) altaicum, U. (U.) bielawskii (Szelegiewicz, 1962) and U. (U.) mulgedii to the subgenus Lambersius Olive.

RESUMEN

Our field data from the Upper Palaeolithic site of Al-Ansab 1 (Jordan) and from a pollen sequence in the Dead Sea elucidate the role that changing Steppe landscapes played in facilitating anatomically modern human populations to enter a major expansion and consolidation phase, known as the "Early Ahmarian", several millennia subsequent to their initial Marine Isotope Stage 4/3 migration from Africa, into the Middle East. The Early Ahmarian techno-cultural unit covers a time range between 45 ka-37 ka BP. With so far more than 50 sites found, the Early Ahmarian is the first fully Upper Palaeolithic techno-cultural unit exclusively and undisputedly related to anatomically modern human populations. In order to better understand the potentially attractive features of the Early Ahmarian environmental context that supported its persistence for over 8,000 years, we carried out a decennial research program in Jordan and in the Dead Sea. This included (1) a geoscientific and archaeological survey program in the Wadi Sabra (Jordan) with a particular focus on excavations at the Early Ahmarian site of Al-Ansab 1 alongside the detailed analysis of Quaternary sediments from the same area and (2) palaeobotanical research based on Quaternary lake deposits from the Dead Sea. Our pollen data from the Dead Sea indicate slow, low frequency vegetational variation with expanding Artemisia steppe, from 60 to 20 ka BP (MIS 3-2). Here, we see a reciprocal assimilation of southern and northern Levantine vegetation zones thereby enhancing a long-lasting south-to-north steppe corridor. The same integration process accelerated about 40 ka ago, when forested areas retreated in the Lebanese Mountains. The process then extended to encompass an area from Southern Lebanon to the Sinai Peninsula. We argue that, at the same time, the carriers of the Early Ahmarian techno-cultural unit extended their habitat from their original Mediterranean biome (in the North) to the Saharo-Arabian biome (to the South). Our excavation of Al-Ansab 1, a campsite at the eastern margins of the Early Ahmarian settlement area, indicates far reaching annual movements of small, highly mobile hunter-gatherer groups. We assume a low degree of settlement complexity, still allowing for habitat extension of the Early Ahmarian into the margins of the Levantine corridor. Due to our radiometric dates, our combined archaeological and environmental record sheds light on an evolved phase of the Early Ahmarian, around 38 ka ago, rather than the starting phase of this techno-cultural unit. Possible application of our model to the starting phase of the Early Ahmarian remains an aspect of future research.

RESUMEN

BACKGROUND: The Eustachian tube (ET) is considered an organ by itself due to its specific functions. An ET Dysfunction (ETD) is discussed when this tube is unable to ventilate the middle ear properly. Clinically, the patient reports usually some aural fullness, "popping", "under water" sensation as if the ear is clogged. This condition is common affecting at least 5% of the adult population. It can impair quality of life and become disabling. On the other side, the prevalence of nasal septal deviation (NSD) is believed to be around 22.83% in the adult population. Nasal septal deviation is thought to cause a decline in the middle ear ventilation according to certain authors. The primary outcome is to define the predictive value of the side of Eustachian Tube Dysfunction (ETD) symptoms vis-à-vis the side of nasal septal deviation (NSD) in patients having the two conditions concomitantly. METHODS: A cross-sectional study was conducted between July 2018 and September 2019. Overall, 60 consecutive subjects (total of 120 ears), randomly seen at the Otorhinolaryngology Outpatient Clinics at the Eye and Ear International Hospital, Lebanon, all year-round were enrolled and tested without any geographic preferences. The Eustachian Tube Dysfunction Questionnaire (ETDQ) -7 questionnaire was used to evaluate ETD. RESULTS: A significantly higher ETD score was found in males compared to females, in those with left septal deviation compared to right and in those who have symptoms on the left compared to right side. Frequent exposure to higher changes in altitude (commute from home to workplace) was also significantly associated with higher ETD scores (r = 0.265), whereas higher Left Tympanometric peak pressure (TPP in daPa) on tympanometry was significantly associated with lower ETD score (r = - 0.467). Furthermore, 25 patients who had symptoms on the left side had also a septal deviation to the left side (86.2%), whereas 29 (93.5%) patients who had the symptoms on the right side had septal deviation to the right side (p < 0.001). CONCLUSION: Our data highlighted the importance of altitude and geographic distribution of patients especially in a population exposed to barotrauma on a daily basis like the Lebanese population. Tympanometry, on the other hand, failed to correlate with patient reported symptoms and thus needs further evaluation. The reported ETD symptoms of the patient correlates to the side of NSD.

RESUMEN

The present study aimed at evaluating the levels of microbiological contamination, total petroleum hydrocarbons (TPHs), and heavy metals (As, Cd, Hg, and Pb) in the edible tissues of commonly consumed fish (8 species) collected from the marine area of Tripoli, Northern Lebanon. Total coliform levels in all sampled fish, and Escherichia coli levels in Liza ramada only, exceeded the permissible limits set by FAO/WHO 2002. Staphylococcus aureus counts were within the recommended thresholds, while sulfate-reducing bacteria levels were the highest in fish of the genus Liza. Salmonella species and Listeria monocytogenes were not detected in all fish analyzed. Analysis of heavy metals levels showed that arsenic exhibited the highest levels among the assessed metals in all genera. Levels of As in Epinephelus, Diplodus, Oblada, and Liza were above the acceptable limits, while Cd levels were below the permissible limits set by the European Commission. Significant negative correlation was found between levels of As and Hg in muscle tissues and fish size (length). Levels of TPHs were the highest in fish of the genus Epinephelus. Significant difference in TPHs contamination was found within three fish genera, with Epinephelus being the most contaminated.

RESUMEN

BACKGROUND: Since 2011, the protracted Syrian war has had tragic consequences on the lives of the Syrian people, threatening their stability, health, and well-being. The most vulnerable are children, who face interruption of schooling and child labor. This study explored the relationship between social capital and the physical health and emotional well-being of Syrian refugee working children in rural areas of Lebanon. METHODS AND FINDINGS: In this cross-sectional study, we surveyed 4,090 Syrian refugee children working in the Bekaa Valley of Lebanon in 2017. Children (8-18 years) gave direct testimony on their living and social environment in face-to-face interviews. Logistic regressions assessed the association of social capital and social cohesion with the health and emotional well-being of Syrian refugee working children; specifically, poor self-rated health, reporting a health problem, engaging in risky health behavior, feeling lonely, feeling optimistic, and being satisfied with life. Of the 4,090 working children in the study, 11% reported poor health, 16% reported having a health problem, and 13% were engaged in risky behaviors. The majority (67.5%) reported feeling lonely, while around 53% were optimistic and 59% were satisfied with life. The study findings suggest that positive social capital constructs were associated with better health. Lower levels of social cohesion (e.g., not spending time with friends) were significantly associated with poor self-rated health, reporting a physical health problem, and feeling more lonely ([adjusted odds ratio (AOR), 2.4; CI 1.76-3.36, p < 0.001], [AOR, 1.9; CI 1.44-2.55, p < 0.001], and [AOR, 0.5; CI 0.38-0.76, p < 0.001], respectively). Higher levels of social support (e.g., having good social relations), family social capital (e.g., discussing personal issues with parents), and neighborhood attachment (e.g., having a close friend) were all significantly associated with being more optimistic ([AOR, 1.5; CI 1.2-1.75, p < 0.001], [AOR, 1.3; CI 1.11-1.52, p < 0.001], and [AOR, 1.9; CI 1.58-2.29, p < 0.001], respectively) and more satisfied with life ([AOR, 1.3; CI 1.01-1.54, p = 0.04], [AOR, 1.2; CI 1.01-1.4, p = 0.04], and [AOR, 1.3; CI 1.08-1.6, p = 0.006], respectively). The main limitations of this study were its cross-sectional design, as well as other design issues (using self-reported health measures, using a questionnaire that was not subject to a validation study, and giving equal weighting to all the components of the health and emotional well-being indicators). CONCLUSIONS: This study highlights the association between social capital, social cohesion, and refugee working children's physical and emotional health. In spite of the poor living and working conditions that Syrian refugee children experience, having a close-knit network of family and friends was associated with better health. Interventions that consider social capital dimensions might contribute to improving the health of Syrian refugee children in informal tented settlements (ITSs).
