Prevalence of Body Dysmorphic Disorder (BDD) among the Lebanese University students: Associated risk factors and repercussion on mental health
Background: Body Dysmorphic Disorder (BDD) is a psychological illness characterized by persistent and intrusive preoccupation with an imagined or slight defect in appearance. For individuals with BDD, these perceived defects are significant and prominent, leading to emotional distress, depression, anxiety, and impairment in daily functioning. Despite its impact, no prior studies have explored the prevalence of BDD among Lebanese university students. Objectives: This study aimed to determine the prevalence of BDD and investigate its association with mental health status (depression and anxiety), religiosity, eating disorder risk, and self-esteem among Lebanese University students. Methodology: A cross-sectional study was conducted in March 2020, involving students from the Lebanese University. Data were collected using the dysmorphic concern questionnaire (DCQ), Rosenberg self-esteem scale (RSE), religiosity scale, patient health questionnaire (PHQ-9), generalized anxiety disorder assessment (GAD-7), Eating Attitude test-26 scale (EAT-26). Results: A total of 6448 participants were enrolled in our study. The overall prevalence of BDD among university students was (6.4%).Our results showed that Lebanese students with BDD were more likely to have anxiety ORadj 1.3 (95% CI:1.2-1.7) p-value 0.001, depression ORadj 1.2 (95% C:1.15-1.5) p-value 0.007, and eating disorder (Bulimia & Food preoccupation ORadj 1.06 (95% CI:1.03-1.2) P-value 0.0, and oral control ORadj 1.09 (95% CI:1.05-1.1) P-value < 0.001) compared to those with no BDD. We also found that students with BDD had Lower Self-esteem ORadj 0.88 (95%CI: 0.78-0.9) P-value <0.001), and less likely to be religious ORadj 0.88 (95%CI: 0.82-0.9) P-value 0.02) compared to those with no BDD. Conclusion: This pioneering study in Lebanon sheds light on the prevalence of BDD among Lebanese university students and its associated factors. BDD was found to be significantly linked to elevated levels of depression, anxiety, and eating disorders, along with lower levels of self-esteem and religiosity. These findings underscore the importance of early detection of BDD during adolescence and young adulthood, necessitating timely psychological intervention to prevent chronicity and complications. Moreover, promoting widespread awareness through various social media and public platforms is essential to address this psychological issue effectively
The CYP7A1 gene rs3808607 variant is associated with susceptibility of tuberculosis in Moroccan population
Introduction: Despite the medical progress in treatment. Tuberculosis (TB) continues to be a serious global health problem. A genome-wide linkage study identified a major susceptibility locus on chromosomal region 8q12-q13 in Moroccan TB patients. The CYP7A1 gene is located in this region and codes for cholesterol 7a-hydroxylase, an enzyme involved in cholesterol catabolism. Methods: We selected three SNPs (rs3808607, rs8192875 and rs8192879) and studied their genotype and allele frequencies distribution in patients with pulmonary (PTB) or pleural TB (pTB), and compared them to Healthy Controls (HC). Genotyping of rs8192875 and rs8192879 SNPs was carried out using the Taq Man SNP genotyping Assay while rs3808607 was investigated by PCR-RFLP.Results: We reported here for the first time a statistically significant increase in the AA homozygote genotype frequency of rs3808607 in PTB patients compared to HC (p = 0.02, OR = 1.93, 95% CI: 1.93 (1.07;3.49). The increased risk of developing TB was maintained when we combined the groups of patients (PTB-pTB) (p = 0.01, OR= 1.91, 95% CI = (1.07 - 3.42). In contrast, no genetic association was observed between the rs8192875 or rs8192879 polymorphisms and TB. Conclusion: Our investigations suggest that rs3808607 may play a role in susceptibility to TB in a Moroccan population.Key words: Tuberculosis, cholesterol 7-alpha-hydroxylase, polymorphisms, SNPs, cholestero
Knowledge and Attitude towards Monkeypox among the Lebanese Population and their Attitude towards Vaccination
Monkeypox is a currently re-emerging disease in the world and several cases have been detected in Lebanon. For this reason, an assessment of the knowledge and attitude of the Lebanese population towards monkeypox and smallpox or monkeypox vaccines had to be done. A cross-sectional study was conducted using a questionnaire developed from previous literature among a sample of Lebanese residents. It recorded the sociodemographic characteristics and comorbidities of the participants and analyzed the patterns of knowledge and attitudes in Lebanon. Among 493 participants, it was found that there is a generally low knowledge of and an average attitude toward monkeypox. However, knowledge is better with higher educational levels, COVID-19 vaccination, and residency in the south of Lebanon and poorer with marriage and residency in Beirut. Attitude is better in females but poorer with higher educational levels. Several other effectors have been devised too. As for vaccination, taking the smallpox vaccine as a proactive measure is predicted with previous COVID-19 vaccination and better attitude but not in the residents of the north of Lebanon and married Lebanese residents. Higher educational levels and a better attitude were positive predictions of taking the monkeypox vaccine whenever it is developed. This study provided insights into the level of knowledge and attitude towards monkeypox and its vaccines, which can be a rich resource when proactive measures are developed
Lebanese University Students and COVID-19: A Survey on their Related-Knowledge, Practice, and Behaviors: Lebanese University Students and COVID-19
Introduction Young adults are at the epicenter for preventing the progression of COVID-19 pandemic and must be targeted for education to impede any potential transmission of the disease. This study aimed to assess the knowledge, practice and behaviors of Lebanese university students regarding COVID-19. Methods A cross-sectional study was carried out among university students at the Lebanese University between March 30, 2020, and April 4, 2020. Information on socio-demographic data, knowledge, practice, and additional information concerning COVID-19 were collected. Results Our survey showed that the majority of the students had good knowledge 90.8%, and more than two third of the respondents 78.6% reported good practice regarding COVID -19. Graduate students were more knowledgeable compared to undergraduate students (unstandardized beta 0.349 with a 95% confidence interval (CI) of 0.165 to 0.533; P- value<0.0001). Moreover, male students had a negative impact on good practice compared to females (unstandardized beta -0.280 with a 95% confidence interval (CI) of -0.402 to -0.159; P- value <0.0001). Nearly half of the students (55.2%) reported that their food intake has increased, and 82.5% of the students didn’t practice sport during the quarantine. The most common information source of the students was the television (63.3%) followed by social media (53.9%). Conclusions This study offers useful insights into the knowledge and practices of Lebanese university students towards COVID-19. Our findings support the importance to deliver health education campaign by the ministry of public health through television and social media to improve the knowledge on disease transmission and preventive measures

Genomic Characterization of Candidate Division LCP-89 Reveals an Atypical Cell Wall Structure, Microcompartment Production, and Dual Respiratory and Fermentative Capacities
© 2019 American Society for Microbiology. Recent experimental and bioinformatic advances enable the recovery of genomes belonging to yet-uncultured microbial lineages directly from environmental samples. Here, we report on the recovery and characterization of single amplified genomes (SAGs) and metagenome-assembled genomes (MAGs) representing candidate phylum LCP-89, previously defined based on 16S rRNA gene sequences. Analysis of LCP-89 genomes recovered from Zodletone Spring, an anoxic spring in Oklahoma, predicts slow-growing, rod-shaped organisms. LCP-89 genomes contain genes for cell wall lipopolysaccharide (LPS) production but lack the entire machinery for peptidoglycan biosynthesis, suggesting an atypical cell wall structure. The genomes, however, encode S-layer homology domain-containing proteins, as well as machinery for the biosynthesis of CMP-legionaminate, inferring the possession of an S-layer glycoprotein. A nearly complete chemotaxis machinery coupled to the absence of flagellar synthesis and assembly genes argues for the utilization of alternative types of motility. A strict anaerobic lifestyle is predicted, with dual respiratory (nitrite ammonification) and fermentative capacities. Predicted substrates include a wide range of sugars and sugar alcohols and a few amino acids. The capability of rhamnose metabolism is confirmed by the identification of bacterial microcompartment genes to sequester the toxic intermediates generated. Comparative genomic analysis identified differences in oxygen sensitivities, respiratory capabilities, substrate utilization preferences, and fermentation end products between LCP-89 genomes and those belonging to its four sister phyla (Calditrichota, SM32-31, AABM5-125-24, and KSB1) within the broader FCB (Fibrobacteres-Chlorobi-Bacteroidetes) superphylum. Our results provide a detailed characterization of members of the candidate division LCP-89 and highlight the importance of reconciling 16S rRNA-based and genomebased phylogenies
