RESUMEN

BACKGROUND: Chronic obstructive pulmonary disease (COPD) has a significant impact on quality of life and is costly to the health care system. It has been demonstrated that a self-management program improves quality of life, but programs are not universally available and telehealth interventions can provide home-based support, but have mixed results. AIM: The aims of this study are to (1) assess the feasibility and acceptability of a 6 weeks' educational program related to self-management with remote monitoring for Lebanese COPD patients; (2) pre-test its impact on quality of life, emergency visits, and rate of rehospitalization, and (3) to make recommendations for a future randomized trial. METHODS: Validated questionnaires will be adapted to meet the context of our study in terms of acceptability, adoption, adequacy, fidelity, cost, and coverage. The impact of this program on quality of life will be measured with the COPD assessment test (CAT) and the COPD clinical questionnaire (CCQ), and the Hospital Anxiety and Depression (HAD) scale will be used to measure anxiety. All measures will be delivered pre- and post-intervention. To evaluate the impact of our program on the rate of hospitalization and emergency visits, the number of hospitalizations and emergency room visits during the year preceding the intervention will be collected from the hospital register of each participant. DISCUSSION: This study is the first to evaluate the application of telehealth to optimize COPD management in Lebanon. The results of this study will provide evidence regarding the efficacy and feasibility of this approach for Lebanese patients with moderate to severe COPD.

RESUMEN

Lebanon invested in the prevention of maternal mortality after the civil war, which left a deficient vital registration system leading to unreliable estimates of maternal mortality ratio (MMR). Starting in 2004, the Ministry of Public Health integrated reproductive health into primary health care and established a national notification system of maternal and neonatal deaths. From 1990 to 2013, Lebanon achieved an annual change in MMR of -7.5%, which was the highest rate of reduction in the region and met the requirements of Millennium Development Goal 5. For the period 2010-2018, data collected through the national notification system indicate an MMR of 14.9, which is below the officially reported MMR of 23. Since the influx of Syrian refugees, Lebanon has experienced a rise in the number of live births with a slightly increasing trend in MMR, especially in regions with the highest concentration of refugees. Causes of maternal mortality in Lebanon align with the three-delays model, pointing to deficiencies in the quality of maternity care. More efforts are needed toward strengthening the national notification system to include cases that occur outside hospitals, identifying near-miss cases, reinforcing the emergency response system, and engaging with all stakeholders to improve quality of care.

RESUMEN

Phenotypic heterogeneity is often observed in patients with telomeropathies caused by pathogenic variants in telomere biology genes. However, the roles of recessive variants in these different phenotypes are not fully characterized. Our goal is to describe the biological roles of a novel homozygous RTEL1 variant identified in a consanguineous Lebanese family with unusual presentation of telomeropathies. A proband was screened for germline variants in telomere biology genes by whole exome sequencing. Leukocytes' telomere length was measured in the proband and eight relatives. We identified a novel homozygous p.E665K RTEL1 variant in the proband, his mother, and seven siblings that associated with telomere shortening and a broad spectrum of clinical manifestations, ranging from mild unspecific findings to severe phenotypes. Consanguinity in at least three family generations led to increased frequency of the homozygous p.E665K variant in the youngest generation and progressive telomere shortening. The increased frequency of the homozygous RTEL1 variant due to consanguinity in this Lebanese family allowed us to infer novel behaviors of recessive RTEL1 variants, as the expressivity and penetrance of this gene are very heterogenous between inter- and intra-generations. Progressive telomere shortening was associated with disease anticipation, first reported in recessive autosomal telomeropathies. Both genetic testing and telomere length measurement were critical for the clinical diagnosis of this family with telomere diseases marked by phenotypic heterogeneity.

RESUMEN

BACKGROUND: To the best of our knowledge, no studies have been conducted in order to assess the correlation of these factors with the self-esteem in Lebanon. Therefore, this study aims to assess risk factors associated with self- esteem among a representative sample of the Lebanese population. SUBJECTS AND METHODS: A cross-sectional, conducted between November 2017 and March 2018, enrolled 789 participants. Self-esteem was measured using the Rosenberg scale. An exploratory factor analysis was executed to detect patterns of risk factors associated with self-esteem from our sample. A cluster analysis was then performed with the identified factor scores to identify the different profiles of the participants. RESULTS: Relationship management (Beta=0.117), emotional awareness (Beta=0.074) and personal accomplishment (Beta=0.064) were associated with a higher self-esteem, whereas high depression (Beta=-0.102), alexithymia (Beta=-0.077), burnout depersonalization (Beta=-0.078), suicidal ideation (Beta=-0.391) were associated with a lower self-esteem. Factor 1 (High emotional intelligence & low depersonalization) (Beta=1.819) was associated with increased self-esteem, whereas Factor 2 (High suicidal ideation, high alcohol dependence, high depression and anxiety) and Factor 3 (High burnout, high stress and high alexithymia) were associated with decreased self-esteem (Beta=-1.380 and Beta=-0.751) respectively. Being widowed (Beta=-2.332), belonging to cluster 1 (People with emotional dysregulation) (Beta=-2.850) and cluster 2 (People in distress) (Beta=-3.660) were significantly associated with decreased self-esteem. CONCLUSIONS: Depression, anxiety, burnout, stress, low emotional intelligence, alexithymia, suicide ideation, alcohol dependence and many other factors can be prevented, or reduced, by interventions that improve self-esteem.

RESUMEN

The species of genus Lacon Laporte, 1838 from the Levant are taxonomically revised. Currently, 18 species are known from the area covering the island of Cyprus and mainland from Hatay province of Turkey to Israel. Six species are described as new for science: Lacon mucheibensis sp. nov. (Israel), L. qatanensis sp. nov. (Syria), L. platiai sp. nov. (Jordan), L. safitensis sp. nov. (Syria), L. tafilensis sp. nov. (Jordan), and L. zenobiae sp. nov. (Lebanon, Syria). Lacon freidbergi Platia, 2010 is synonymized with L. lithophilus (Candèze, 1857), and L. kapleri Platia Schimmel, 1994 with L. graecus (Candèze, 1857). Lacon drusus (Marseul, 1870) is recorded for the first time from Israel. Lacon lithophilus is recorded for the first time from Israel and Jordan. Lacon graecus is removed from the fauna of Levant, because all earlier reports of this species from Lebanon and Syria were based on misidentifications. Figures of habitus and main diagnostic features are provided for all species and an identification key to the Lacon species of the Levant is given.

RESUMEN

In this study, we examine the economic and environmental significance associated with the implementation of an EU waste-separated collection scheme in a developing context - Lebanon. Two scenarios, S1 and S2, representing different intensities of source segregation were analysed. In S1, the average source segregation intensity reached 25% and 13% for the Italian test area and Lebanese test area, respectively. In S2, source segregation intensity increased to 48% and 68% for the Italian and Lebanese test areas, respectively. Passing from S1 to S2 increased collection costs significantly, up to 44% with greater increases in the Italian test area where labour cost is higher. In both areas, environmental impacts decreased with greater source segregation intensity. Savings in the climate change impact and stratospheric ozone depletion potential were lower under the Lebanese test area in comparison with the Italian test area. In contrast, savings in freshwater eutrophication and acidification impact were lower for the Italian test area. The increase in the source segregation intensity resulted in maximum savings for the depletion of abiotic resources, 74% to 77% and 79% to 80% in a developing and developed context, respectively.

RESUMEN

Purpose: Because of the high rate of agenesis and supernumerary teeth in orthodontic patients and the lack of studies in Lebanon that document the prevalence of those anomalies, the aim of this study was to determine the prevalence of hypodontia and supernumerary teeth in patients attending a pediatric dental office and examine the associated factors. Study design: This was a cross-sectional design study. The patients were clinically examined followed by panoramic radiograph. Two calibrated investigators have examined the radiographic films and diagnosed the dental anomalies. Tooth agenesis and supernumerary teeth were the outcome variables of the study. Tooth agenesis was diagnosed when there were no sign of crown calcification and no evidence or history of loss attributable to orthodontic treatment, caries, periodontal problems and dental trauma. Tooth agenesis and supernumerary teeth were the outcome variables of the study. Chi-Square tests and Fisher Exact tests were performed to assess the association between outcome variables, gender and presence of medical problem. Results: 334 participants (mean age 7.31±2.17 years) were included in the study. The presence of dental anomalies was not reported as a reason for dental visits. The rate of tooth agenesis was 8.7% in the whole sample, 9.9% among boys and 7.6% among girls with no difference (p=0.442). The rate of tooth agenesis was elevated in participant with medical problems (14.5%) compared to those with no medical problem (7.0%) (p=0.041). The rate of supernumerary teeth was 0.6% among boys and 0% among girls (p=0.485). Conclusion: Oral anomalies could be detected relatively at early age. It can help in a long-term and effective treatment planning. Early diagnosis and appropriate follow-up with panoramic radiograph is extremely important to avoid maxillofacial deformity and other complications.

RESUMEN

The demand for sustainable and eco-friendly control methods of pests and insects is increasing worldwide. From this came the interest in Bacillus thuringiensis, an entomopathogenic bacterium capable of replacing chemical pesticides. However, the possibility of pests developing resistance to a particular strain may impair its use, and there is a need to identify novel strains of this species as potential commercial biopesticides. B. thuringiensis sv. israelensis is one of the most successful serovars, widely commercialized for its activity against black fly and mosquito larvae. In this study, we isolated, characterized, and sequenced a new Lebanese B. thuringiensis sv. israelensis isolate, strain AR23. Compared to the commercialized reference strain AM65-52 (Vectobac®, Sumitomo), AR23 showed an increased activity against several mosquito species. The genomic analysis revealed that this strain, compared to AM65-52, possesses a simplified plasmid content and an additional functional cry4Ba coding gene that most likely accounts for the increased effectiveness of this strain in mosquito larvae killing.

RESUMEN

Total and bioaccessible lead (Pb) concentrations in Dittrichia viscosa and soil samples were considered for estimating the potential health risk, related to both plant intake and accidental soil ingestion by adult and child consumers, near a Lebanese fertilizer plant. A total of 27 plant samples, from 9 uncultivated sites situated around the plant, were analyzed in order to assess the total and bioaccessible Pb content. Physiologically based extraction test (PBET) was used to estimate oral bioaccessibility of Pb in edible plant parts. Washed and unwashed leaves were compared in order to show the importance of good consumer practice on Pb intake. Extracted Pb in the intestinal medium accounted for 24 up to 87% of Pb extracted in the gastric medium. The total hazard quotient (HQtot) and the total bioaccessible hazard quotient (BHQ), related to both plants' intake and soil ingestion, for two maximalist child and adult scenarios, were calculated in order to estimate human health risk assessment. HQtot estimations considering the total concentration of Pb in soil and plant suggest that this metal is a contributor in elevating health risks problems on local plants' consumers, especially children inhabitants. However, the integration of bioaccessible concentrations of Pb in risk estimations reduces remarkably the potential risk.

RESUMEN

Background and Aims: People in Lebanon turned to bottle water consumption because of its poor public water quality. In general, fluoride is known as dental caries preventive. A study in 1986 and two other national surveys in 1994 and 2004 showed that the concentration of fluoride in public Lebanese water was insignificant for the prevention of dental caries (less than 0.3 mg/L). The aim of the study was to measure the fluoride concentration in the highest selling and known commercial brands for bottled water in Lebanon, as well as to assess their effectiveness regarding prevention of dental caries. Result: Fluoride has a notable therapeutic effect but in small doses that fluoride can be found in drinking water. Analysis using an absorptiometry of 625nm and another technique using an Orion electrode of 9609 BN have shown the low content of fluoride in the Lebanese waters (less than 0.3 mg/l). Strategies have recently been evolved based on fluroide supplementation (if the results turn negative) to reduce the index of caries in LEBANON.

RESUMEN

BACKGROUND: Alcohol use is a major risk factor in premature death and disability, especially among youth. Evidence-based policies to prevent and control the detrimental effect of alcohol use have been recommended. In countries with weak alcohol control policies-such as Lebanon, stakeholder analysis provides critical information to influence policy interventions. This paper assesses the views of stakeholders regarding a national alcohol harm reduction policy for youth. METHODS: We interviewed a total of 22 key stakeholders over a period of 8 months in 2015. Stakeholders were selected purposively, to include representatives of governmental and non-governmental organizations and industry that could answer questions related to core intervention areas: affordability, availability, regulation of marketing, and drinking and driving. We analyzed interview transcripts using thematic analysis. RESULTS: Three themes emerged: Inadequacy of current alcohol control policies; weak governance and disregard for rule of law as a determinant of the status quo; and diverting of responsibility towards 'other' stakeholders. In addition, industry representatives argued against evidence-based policies using time-worn strategies identified globally. CONCLUSIONS: Our findings indicate that alcohol harm reduction policies are far from becoming a policy priority in Lebanon. There is a clear need to shift the narrative from victim blaming to structural conditions.

RESUMEN

Assessing land degradation is essentially needed for decision-makers to monitor and mitigate degradation and implement sustainable land management practices. More specifically, monitoring land degradation on a regular basis enables decision-makers to analyze impact of degradation and effects of sustainable land management practices. This requires adopting a precise methodology for assessing land degradation. With information form assessments, decision-makers can establish achievable management goals to attain land degradation neutrality as addressed by the Sustainable Development Goal 15 (i.e., SDG 15). Accordingly, this work aimed at developing a systematic approach for assessing land degradation at the subnational level with the combined use of geo-spatial information and field data. The specific objectives were to (1) assess trends in land degradation and the impact of historical land uses on the current landscape characters, (2) investigate and characterize principal criteria of land degradation, and (3) identify sustainable land management practices. Multi-source and multi-resolution spatial data were employed for assessing the three indicators of land degradation neutrality (i.e., changes in vegetation cover, land productivity, and soil organic carbon). Prioritizing lands prone to degradation was investigated using a set of spatial attributes of different weights. Field data collection involved the use of pre-defined set of questions for assessing the principal criteria of land degradation including type, extent, rate, degree, and causes of land degradation. Sustainable land management practices were identified and categorized accordingly. This assessment provided a means for prioritization of interventions (i.e., prevention, mitigation, and/or rehabilitation) in an area characterized by a climate varying from semi-arid to moist subhumid.

RESUMEN

Introduction : Problem-based learning (PBL) has been introduced in university nursing programs following the implementation of the competency-based approach (CBA). This innovation required a pedagogical reform, hence the interest in this method. PBL stimulates students to develop critical thinking, identified as the most important challenge for nursing education in the twenty-first century.Background : Several studies have been conducted to understand undergraduate nursing students' perceptions of the use of PBL in the learning process. The results have highlighted the positive and negative aspects of this method.Objective : The purpose of this article is to explore student nurses' perceptions of the evaluation of PBL in their learning process.Method : A descriptive qualitative study of twenty student nurses was carried out using semi-structured individual interviews.Results : The results of the study highlighted the positive and negative aspects of PBL, as perceived by the students. Positive aspects include the development of friendly relationships in subgroups, behavioral changes in learning, and the development of student autonomy. Negative aspects include a feeling of having insufficient knowledge, time management difficulties during learning, and the lack of cohesion in the group.Conclusion : Results from this study would help develop learning promotion strategies in order to help students become more active in their learning process.
