Background: Medication non-adherence is a significant barrier to optimal treatment goals. The study explores the association between subjective well-being (SWB) and medication adherence among Lebanese individuals with multiple chronic diseases and identifies additional factors that may influence adherence in this population. Methods: An exploratory, cross-sectional study was conducted for three months at six community pharmacies. Adherence was assessed using the Adherence to Refills and Medication Scale Arabic Lebanese Version (ARMS-A). The SWB was measured using the Arabic Scale of Happiness (ASH), Love of Life Scale (LLS), Arab Hope Scale (AHS), and Satisfaction with Life Scale (SWLS). Spearmen's Rho correlation analyzed the association between ARMS-A and SWB constructs. Binary logistic regression identified predictors of adherence among individuals with chronic diseases and on multiple chronic medications. Results: Of 400 participants, 106 (26.5 %) with a 95 % CI, 0.22–0.31, were adherent. Lower medication adherence (reflected in higher ARMS-A scores) was associated with lower SWB (p = 0.01). Multivariate analysis showed that lower education (OR=2.21, 95 % CI, 1.01–4.81), lack of a specific diet (OR = 1.64, 95 % CI, 1.01–2.69), and frequent hospital and/or emergency visits (OR=3.29, 95 % CI, 1.75–6.17 for 2 visits; OR = 2.71, 95 % CI, 1.43–5.14 for ≥3 visits) significantly increased the odds of non-adherence to chronic treatment. However, higher income (OR = 0.06, 95 % CI, 0.01–0.38), healthcare provider occupation (OR = 0.42, 95 % CI, 0.21–0.48), and having diabetes mellitus (OR = 0.59, 95 % CI, 0.36–0.96) correlated with better adherence. Conclusion: A significant portion of participants failed to adhere to their prescribed chronic medications, influenced by multicomplex socioeconomic, psychological, and health-related factors. These findings demonstrate the need for culturally-tailored, pharmacist-led interventions to improve medication adherence and overall health outcomes.

This study aims to test the applicability of the functional theory of life values and score differences among a group of students from Lebanon and Portugal. Participants include 565 college students--278 Lebanese and 287 Portuguese. A demographic questionnaire and an adapted version of the Basic Values Survey were completed. Confirmatory/multigroup factor analysis, a generalized Procrustes analysis, and a t test were used. Results indicate that content and structure hypotheses were equivalent among the two groups. There were significant differences between the Lebanese and Portuguese students in normative and promotion values in favor of the first group, and in interactive, suprapersonal, and excitement values in favor of the second. This study has implications for institutional academic and social practices with international college students.

We studied the biodegradation of oily sludge generated by a petroleum plant in Bahrain by a bacterial consortium (termed as AK6) under different bioprocess conditions. Biodegradation of petroleum hydrocarbons in oily sludge (C11-C29) increased from 24% after two days to 99% after 9 days of incubation in cultures containing 5% (w/v) of oily sludge at 40°C. When the nitrogen source was excluded from the batch cultures, hydrocarbon biodegradation dropped to 45% within 7 days. The hydrocarbon biodegradation decreased also by increasing the salinity to 3% and the temperature above 40°C. AK6 tolerated up to 50% (w/v) oily sludge and degraded 60% of the dichloromethane-extractable oil fraction. Illumina-MiSeq analyses revealed that the AK6 consortium was mainly composed of Gammaproteobacteria (ca. 98% of total sequences), with most sequences belonging to Klebsiella (77.6% of total sequences), Enterobacter (16.7%) and Salmonella (5%). Prominent shifts in the bacterial composition of the consortium were observed when the temperature and initial sludge concentration increased, and the nitrogen source was excluded, favoring sequences belonging to Pseudomonas and Stenotrophomonas. The AK6 consortium is endowed with a strong oily sludge tolerance and biodegradation capability under different bioprocess conditions, where Pseudomonas spp. appear to be crucial for hydrocarbon biodegradation.

Background The Eight‐item Fear Scale is a unidimensional scale evaluating the perceived feelings of fear associated with the thought of the coronavirus. Aim The Arabic version of this scale did not exist; hence, this study aimed to translate and evaluate the psychometric properties of the Fear Scale in participants aged 18 years and above in five Arabic countries: Egypt, Lebanon, Libya, Saudi Arabia, and Sudan by using a cross‐sectional survey design. Method The English version of the COVID‐19 Fear Scale was translated into Arabic following the guidelines and disseminated through social media. Factorial and convergent validity and internal reliability were evaluated. Results: The total number of participants was 2783; the majority was young (41.9%) and female (60.5%). Fear scores were moderate in four countries and severe in Egypt. The scale showed good structural validity, with the items explaining up to 70% of the variance. The scale items correlated significantly with the total scores, and the Cronbach alpha was above 0.9. Conclusion The study concluded that the Arabic Fear Scale is a psychometrically robust scale that can be used to evaluate the perceived feelings of fear with the thought of the coronavirus or pandemic in general.

We enriched and characterized a biodesulfurizing consortium (designated as MG1). The MG1 consortium reduced the total sulfur of diesel by 25 % and utilized each of the diesel-born compounds dibenzothiophene (DBT), benzothiophene (BT), 4-methyldibenzothiophene (4-MDBT) and 4, 6-dimethyldibenzothiophene (4, 6-DMDBT) as a sole sulfur source. MiSeq analysis revealed compositional shifts in the MG1 community according to the type of the sulfur source. A DBT-grown MG1 culture had Klebsiella, Pseudomonas, Rhodococcus and Sphingomonas as the most abundant genera. When diesel or 4, 6-DMDBT was provided as a sole sulfur source, Klebsiella and Pseudomonas spp. were the most abundant. In the BT culture, Rhodococcus spp. were the key biodesulfurizers, while Klebsiella, Pseudomonas and Sphingomonas spp. dominated the 4-MDBT-grown consortium. MG1 also utilized 2–hydroxybiphenyl (the product of the 4S biodesulfurization pathway) where Pseudomonas spp. uniquely dominated the consortium. The data improves our understanding of the sulfur source-driven structural adaptability of biodesulfurizing consortia.

Summary Heavy vacuum gas oil (HVGO) is a complex and viscous hydrocarbon stream that is produced as the bottom side product from the vacuum distillation units in petroleum refineries. HVGO is conventionally treated with thermochemical process, which is costly and environmentally polluting. Here, we investigate two petroleum biotechnology applications, namely valorization and bioupgrading, as green approaches for valorization and upgrading of HVGO. The Pseudomonas aeruginosa AK6U strain grew on 20% v/v of HVGO as a sole carbon and sulfur source. It produced rhamnolipid biosurfactants in a growth‐associated mode with a maximum crude biosurfactants yield of 10.1 g l−1, which reduced the surface tension of the cell‐free culture supernatant to 30.6 mN m−1 within 1 week of incubation. The rarely occurring dirhamnolipid Rha–Rha–C12–C12 dominated the congeners’ profile of the biosurfactants produced from HVGO. Heavy vacuum gas oil was recovered from the cultures and abiotic controls and the maltene fraction was extracted for further analysis. Fractional distillation (SimDist) of the biotreated maltene fraction showed a relative decrease in the high‐boiling heavy fuel fraction (BP 426–565 °C) concomitant with increase in the lighter distillate diesel fraction (BP 315–426 °C). Analysis of the maltene fraction revealed compositional changes. The number‐average (Mn) and weight‐average (Mw) molecular weights, as well as the absolute number of hydrocarbons and sulfur heterocycles were higher in the biotreated maltene fraction of HVGO. These findings suggest that HVGO can be potentially exploited as a carbon‐rich substrate for production of the high‐value biosurfactants by P. aeruginosa AK6U and to concomitantly improve/upgrade its chemical composition.

Free space optics (FSO) provides high data rate by allowing transmission of signal through atmosphere. FSO is affected by different weather conditions. The atmospheric attenuation is caused by two main factors; absorption and scattering. Fog, rain, snow and cloud cause the scattering of optical signals transmitted in free space. Fog is the most critical attenuating factor. In this paper, a new idea to overcome the atmospheric attenuation is discussed using adaptive transmitter and receiver design based on the transmitted power equation that depends on the weather conditions. The obtained results show a huge performance enhancement in the signal to noise ratio (SNR) and bit error rate (BER). Keywords: Free space optics, Atmospheric attenuation, Adaptive receiver

We followed a comparative approach to investigate how heavy vacuum gas oil (HVGO) affects the expression of genes involved in biosurfactants biosynthesis and the composition of the rhamnolipid congeners in Pseudomonas sp. AK6U. HVGO stimulated biosurfactants production as indicated by the lower surface tension (26 mN/m) and higher yield (7.8 g/L) compared to a glucose culture (49.7 mN/m, 0.305 g/L). Quantitative real-time PCR showed that the biosurfactants production genes rhlA and rhlB were strongly upregulated in the HVGO culture during the early and late exponential growth phases. To the contrary, the rhamnose biosynthesis genes algC, rmlA and rmlC were downregulated in the HVGO culture. Genes of the quorum sensing systems which regulate biosurfactants biosynthesis exhibited a hierarchical expression profile. The lasI gene was strongly upregulated (20-fold) in the HVGO culture during the early log phase, whereas both rhlI and pqsE were upregulated during the late log phase. Rhamnolipid congener analysis using high-performance liquid chromatography-mass spectrometry revealed a much higher proportion (up to 69%) of the high-molecularweight homologue Rha–Rha–C10–C10 in the HVGO culture. The results shed light on the temporal and carbon source-mediated shifts in rhamonlipids’ composition and regulation of biosynthesis which can be potentially exploited to produce different rhamnolipid formulations tailored for specific applications.

A Pseudomonas aeruginosa AK6U strain produced rhamnolipid biosurfactants to variable extents when grown on MgSO4 or organosulfur compounds as sulfur sources and glucose as a carbon source. Organosulfur cultures produced much higher biosurfactants amounts compared to the MgSO4 cultures. The surface tension of the growth medium was reduced from 72 mN/m to 54 and 30 mN/m in cultures containing MgSO4 and 4,6-dimethyldibenzothiophene (4,6-DM-DBT), respectively. AK6U cultures produced different rhamnolipid congener profiles depending on the provided sulfur source. The dibenzothiophene (DBT) culture produced more diverse and a higher number of rhamnolipid congeners as compared to the DBT-sulfone and MgSO4 cultures. The number of mono-rhamnolipid congeners in the DBT culture was also higher than that detected in the DBT-sulfone and MgSO4 cultures. Di-rhamnolipids dominated the congener profiles in all the analyzed cultures. The sulfur source can have a profound impact on the quality and quantity of the produced biosurfactants.

Objective: To detect accuracy of PET/CT in the initial staging, response after the first line and end of treatment in early mediastinal lymphoma patients compared to contrast CT. Materials and methods: We studied 50 patients with pathologically proven lymphoma with a mean age = 27.5. All patients were at early stage. All patients performed CT and PET/CT for initial staging, after the first course of chemotherapy (after 4–6 weeks) and at the end of treatment (after 2–4 months). Results: PET/CT upstaged 5 cases. At first line of treatment, PET/CT and CECT were agreeable in 32% of cases. PET/CT showed 100% sensitivity, 96.7% specificity, 95% positive predictive value and 100% negative predictive value. At the end of treatment both methods showed a 46% agreement. PET/CT was statistically significant in the follow up of hilar and axillary lymph nodes. PET/CT showed 100% sensitivity and specificity; compared to 62.5% sensitivity and 97.6% specificity for CECT in detection of extra-nodal disease sites. Conclusion: PET/CT proved higher sensitivity and specificity over CECT. The major strength of PET/CT over CECT was its higher ability for detection of extra-nodal sites of lymphoma and excluding active disease in residual nodal mass lesions on follow up.

The present research studied 2570 college students from seven countries: Egypt, Algeria, Kuwait, Lebanon, Iran, India and Turkey. The aims were: (a) to compare love of life mean scores between the seven samples, (b) to examine sex-related differences in love of life, and (c) to explore the principal components of the Love of Life Scale (LLS). The highest mean total LLS scores were for Kuwait, India, and Iran students, respectively. All countries differed significantly from one another, except Algeria versus Lebanon and India versus Iran. Higher mean LLS scores for women were found for each country. Cronbach alpha for the LLS was.93. A principal component analysis extracted from one to four components for individual countries, but one component was extracted for the total sample and labelled: Positive attitude towards life and Meaningfulness of life. The love of Life concept may be considered to be an important concept in positive psychology. [ABSTRACT FROM AUTHOR]
