Validity and reliability of chemical-based disinfectant use questionnaire in a sample of the Lebanese public community.

Introduction: Worldwide, people heavily use chemical-based disinfectants to prevent the spread of COVID-19 with limited or no safety instructions. Awareness about the safe use of chemical-based disinfectants is highly recommended to limit the spread of COVID-19 and to avoid any health risks when misused, especially in developing countries where a poor healthcare system is prominent. Awareness in this context refers to the understanding and knowledge of proper usage, safety protocols and potential health risks associated with chemical disinfectants.

Evaluation of awareness and performance towards COVID-related disinfectant use: a comparative study between Jordan and United Arab Emirates.

Background: The World Health Organization recommended the use of chemical-based disinfectants as an effective prevention of the COVID-19 pandemic. However, calls for poisoning were reported in several medical centers. The widespread use of chemical-based disinfectants as a preventive measure during the COVID-19 pandemic has underscored potential gaps in community awareness and performance, posing health risks.

Hand hygiene during the spread of COVID-19: a cross-sectional study of awareness and practices among academic institutions in Lebanon.

Introduction: During the pandemic, the World Health Organization has recommended hand hygiene as one of the effective preventive measures to limit the global spread of COVID-19. However, the awareness gap of hand hygiene protocols could increase the spread of COVID-19 and consequently increase the absenteeism rate among academic institutions. This study aims to assess hand hygiene awareness and practices levels among various university communities in Lebanon.

Evaluation of awareness and performance towards COVID-related disinfectant use among the university communities in Lebanon.

Background: The fast spread of COVID-19 reinforced the daily use of disinfectants around the world. However, the awareness gap of disinfectant use could lead to health risks during the prevention of the pandemic. This study aims to assess the level of awareness and performance towards COVID-related disinfectant use among various university communities (student, staff, and faculty) in Lebanon.

Evaluation of public awareness and performance toward the safe use of household disinfectants-cleaners to prevent COVID-19 in the Emirate of Abu Dhabi.

Introduction: Disinfection is one of the most effective hygienic practices that would limit the spread of the Coronavirus Disease (COVID-19) through deactivating the coronavirus on contaminated skin, supplies, and surfaces. However, the type and concentration of disinfectants should be carefully selected to avoid damaging surfaces and to limit the side effects of these chemicals on household members and users. The aim of this study is to assess the public levels of awareness and performance concerning the safe use of household cleaning products and disinfectants during the spread of COVID-19 in the Emirate of Abu Dhabi.

Development and Validation of the Soft Skills Questionnaire for Nurses.

Introduction: Skills challenge has been given great attention for its impact on employees' performance. Various approaches have been put forward to design professional development programs that help in preparing nurses to work in the field and ongoing training programs to keep them up to each new method and technique at the interpersonal improvement level.

Objective: To develop and validate a questionnaire that tests the communication and management skills, emotional intelligence, and confidentiality of nurses in Lebanon.

Prevalence and Behavioral-Based Risk Factors (Eye Cosmetic and Tobacco Use) of Symptomatic Dry Eye Disease in Four Middle Eastern Countries: Lebanon, Syria, Jordan, and Palestine.

Purpose: To estimate the prevalence of symptomatic dry eye disease (DED) in four Middle Eastern Countries and investigate the association between behavioral-based risk factors and severity of DED.

Patients And Methods: Population-based cross-sectional study of 1463 participants from 4 Mediterranean countries (Lebanon, Syria, Jordan, and Palestine). The Arabic version of the Ocular Surface Disease Index (ARB-OSDI) questionnaire was used to estimate the prevalence and severity of symptomatic DED using an online format survey.

Prevalence and risk factors of symptomatic dry eye disease in Lebanon.

Purpose: To estimate the prevalence of symptomatic dry eye disease (DED) and investigate its associated risk factors in the Lebanese population.

Methods: Population-based cross-sectional study of 602 participants from Lebanon aged 18 years and older. Ocular Surface Disease Index (OSDI) questionnaire on dry eye symptoms was used to evaluate the prevalence of symptomatic DED.

Immobilization of membrane-bounded (S)-mandelate dehydrogenase in sol-gel matrix for electroenzymatic synthesis.

Membrane-bounded (S)-mandelate dehydrogenase has been immobilized on the surface of glassy carbon and carbon felt electrodes by encapsulation in a silica film obtained by sol-gel chemistry. Such bioelectrochemical system has been used for the first time for electroenzymatic conversion of (S)-mandelic acid to phenylglyoxylic acid. Apparent Km in this sol-gel matrix was 0.

Electrochemically assisted bacteria encapsulation in thin hybrid sol-gel films.

A novel method, based on the electrochemical manipulation of the sol-gel process, was developed to immobilize bacteria in thin hybrid sol-gel films. This enabled the safe immobilization of Escherichia coli on electrode surfaces. E.
