RESUMO
BACKGROUND: The Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) evaluates perceived cognitive functioning and their impact on quality of life. This study was designed to evaluate the factors associated with cognitive functioning in a sample of women with breast cancer (BC) in Lebanon. We also sought to explore the psychometric properties of the FACT-Cog Arabic version. METHODS: A cross-sectional study was carried out between March and August 2020 among women with BC. Socio-demographic and clinical characteristics were collected. In addition, patients were asked to complete the FACT-Cog Arabic version as well as the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30, the Patient Health Questionnaire (PHQ-9), and the Generalized Anxiety Disorder (GAD-7). The internal consistency of the FACT-Cog tool was evaluated using Cronbach's alpha. Content, convergent, and known group validity of the FACT-Cog Arabic version were also evaluated. All statistical analyses were performed using SPSS version 23.0. RESULTS: A sample of 134 women with BC was collected. Internal consistencies of the FACT-cog total scale and its subscales were high (Cronbach's α between 0.83 and 0.95). The convergent validity of the FACT-Cog Arabic version was supported by the positive correlation with the EORTC-cognitive functioning subscale. Moreover, negative correlations were found between FACT-Cog scale and fatigue, pain, anxiety, as well as depression. Known-group validity was supported by the statistically significant mean differences of the FACT-Cog total scale between patients in early (I &II) and late (III & IV) BC stages. Unmarried BC patients as well as those having higher depressive symptoms and a lower quality of life were found to be at higher risk of cognitive impairment. CONCLUSION: The FACT-Cog Lebanese Arabic version is a valid and reliable tool for assessing perceived cognitive functioning in BC women. Higher level of depression and impaired quality of life were associated with a decline in cognitive functioning.

Background: Glioma is the most frequent primary brain tumor and one of the most aggressive forms of cancer. Recently, numerous studies have focused on cannabinoids as a new therapeutic approach due to their antineoplastic effects through activation of the cannabinoid receptors. This study aimed to investigate the immunohistochemical expression level of cannabinoid type-1 receptors (CB1R) in human glioma samples and evaluate its clinicopathologic significance. Materials and methods: We analyzed the expression of CB1R in 61 paraffin-embedded glioma and 4 normal brain tissues using automated immunohistochemical assay. CB1R expression was categorized into high versus low expression levels. Statistical analyses were performed to evaluate the association between CB1R and phosphorylated extracellular signal-related kinase (p-ERK) expression levels and the clinicopathologic features of glioma. Results: Our results showed that CB1R immunopositivity was seen in 59 of 61 cases (96.7%). CB1R was down-expressed in glioma compared to normal brain tissues. However, CB1R expression was not correlated with clinicopathological parameters except for p-ERK. Conclusion: Our findings indicate the down-expression of CB1R in glioma tissues when compared to non-cancerous brain tissues. This change in CB1R expression in gliomas should be further tested regardless of the clinicopathological findings to provide a therapeutic advantage in glioma patients.

BACKGROUND: Non-progressive dysarthria is an acquired motor speech disorder resulting from neurological diseases such as stroke and traumatic brain injury. The evidence base for the assessment of non-progressive dysarthria remains limited with professional practices relying mainly on therapists' clinical experience. Limited information on the assessment practices of Lebanese speech and language therapists (SLTs) is available. Such information is crucial for the development of adequate therapy services for clients with non-progressive dysarthria. This study aims to explore the assessment practices and attitudes of Lebanese SLTs working with adults with non-progressive dysarthria and to investigate their adherence to the framework of the World Health Organization's International Classification of Functioning, Disability and Health (ICF). METHODS: A cross-sectional study was conducted in Lebanon between March and May 2021. Data was collected through an online survey that included information on socio-demographic characteristics, practices, and attitudes of SLTs who assess adults with non-progressive dysarthria. RESULTS: A total of 50 Lebanese SLTs responded to the survey. The majority of SLTs (78%) assessed clients with non-progressive dysarthria across all ICF domains. SLTs reported dissatisfaction with the available assessment tools (64%) and reliance on informal tools (84%). In addition, 68% of the SLTs suggested the crucial need for the development of Arabic formal assessments that can quantitatively evaluate dysarthria and determine severity. The survey also showed that the respondents demonstrated a preference for the use of impairment-based tools. CONCLUSION: It can be concluded that the assessment practices of Lebanese SLTs, generally, follow the international trend and the recommended professional guidelines. Further research initiatives should be held to develop Arabic formal assessment tools for non-progressive dysarthria.

BACKGROUND: Dental anxiety continues to be a widespread problem affecting adult populations. The primary aim of our study was to evaluate the psychometric properties of the Lebanese Arabic version of the Modified Dental Anxiety Scale (MDAS-A) and to identify the optimal cut-off for assessing dental anxiety and dental phobia among adults in Lebanon. In addition, we sought to assess dental anxiety and phobia as well as their correlates among Lebanese adult patients. METHODS: A cross-sectional study was carried out on a sample of 451 dental adult patients aged between 18 and 65 years old. Information about demographic characteristics, previous bad dental experience, trauma's experience period, perception of a periodontal problem, sensation of nausea during dental treatment, the MDAS-A scale, and the Visual Analogue Scale for anxiety (VAS-A) were collected. RESULTS: MDAS-A exhibited evidence of adequate psychometric properties. The optimal cut-off was 12 for dental anxiety and 14 for dental phobia. Out of the total sample, 31.5% suffered from dental anxiety while 22.4% had a dental phobia. Multivariable analysis showed that the odds of dental anxiety and phobia were higher among females compared to males. Also, patients suffering from periodontal problem perceptions, bad dental experiences during childhood and adolescence, and the sensation of nausea during dental treatment were at a higher risk of developing dental anxiety and phobia compared to their counterparts. However, a higher level of education was found to be a protective factor against dental phobia among Lebanese adult patients. CONCLUSION: The MDAS-A scale is a suitable tool for the routine assessment of dental anxiety and phobia among Lebanese adult patients. Identifying patients with dental anxiety at the earliest opportunity is of utmost importance for delivering successful dental care.

This study aims to examine the psychometric properties of an Arabic version of the Neuropsychiatric Inventory Questionnaire (NPI-Q) that evaluates neuropsychiatric symptoms in patients with dementia. A cross-sectional study was carried out with a sample of 136 Lebanese demented patients aged 63-98 years. NPI-Q was completed by the patients' primary caregiver and standard NPI was administered through personal interview by an experienced research assistant to the same caregiver. The internal consistencies of the Arabic NPI-Q total and distress scale were 0.680 and 0.684 respectively. One week test-retest reliability of the total NPI-Q and distress scores were 0.991 and 0.988 respectively (p-value <0.0001 for both). The NPI-Q correlated significantly with the standard NPI in individual and total symptom scores as well as caregiver distress scores. Exploratory factor analysis extracted five factors that explained 64.7% of variances. The prevalence of analogous symptoms reported on the NPI and NPI-Q differed on average by 3% while moderate or severe symptom ratings differed on average by 1%. The Arabic version of the NPI-Q showed evidence of good psychometric properties indicating that it is a suitable tool for the routine assessment of neuropsychiatric symptoms for Lebanese patients with dementia in clinical settings.

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.

The aim of this study was to generate normative data on the M-WCST in a Lebanese adult population and to examine the relationship between performance on this task and demographic variables. The sample consisted of 220 healthy adults aged between 18 and 64 years. Regression-based strategy was applied to generate normative data. The results showed a statistically significant effect of age and level of education on the M-WCST measures, whereas gender was not significant. Demographically calibrated percentiles and scaled scores were created. Finally, this study was the first to provide normative-adjusted tables for the M-WCST scores in Lebanon.
