RESUMO

BACKGROUND: Meta-analytic findings documented a substantial impact of self-esteem on a broad range of psychological and behavioral indicators, thus highlighting its high clinical relevance. Proving a simple and cost-effective measure of global self-esteem to the Arabic-speaking community, who mostly live in low- and middle-income countries, and where research may be challenging, would be highly valuable. In this context, we sought to investigate the psychometric characteristics of an Arabic translation of the Single-Item Self-Esteem Scale (A-SISE) in terms of factor structure, reliability, and construct validity. METHODS: A total of 451 participants were enrolled between October and December 2022. An anonymous self-administered Google Forms link was shared on WhatsApp. To examine the factor structure of the A-SISE, we used the FACTOR software. We conducted an exploratory factor analysis (EFA), using a principal component analysis on the Rosenberg Self-Esteem Scale (RSES) items first, then after adding the A-SISE. RESULTS: The results of the EFA of the RSES revealed two factors (F1 = negatively-worded items; F2 = positively-worded items), which explained 60.63% of the common variance. When adding the A-SISE, the two-factor solution obtained explained 58.74% of the variance, with the A-SISE loading on the second factor. Both RSES and A-SISE correlated significantly and positively with each other, as well as with extroversion, agreeableness, conscientiousness, open mindedness and satisfaction with life. Moreover, they correlated significantly and negatively with negative emotionality and depression. CONCLUSION: These results suggest that the A-SISE is a simple-to-use, cost-effective, valid and reliable measure of self-esteem. We thus recommend its use in future research among Arabic-speaking people in Arab clinical and research settings, particularly when researchers are limited by time or resources constraints.

RESUMO

Background & objectives: A high incidence of hearing impairment is reported from the village of Dhadkai in the State of Jammu and Kashmir, India. Prevalence of endogamy in this community suggested a common genetic basis for the disorder. A genetic study was undertaken to ascertain the basis for the high incidence of hearing impairment in this region. Methods: In a two-step approach to identify the causative mutation/s, a whole-genome-based linkage analysis of an extended family of 45 members was carried out, which included 23 affected and 22 unaffected members. Mutational analysis for the candidate deafness genes helped reveal causative mutations in the family. In addition, seven deafness-causing genes, Cx26, SLC26A4, CLDN14, TMPRSS3, TMC1, TMIE and USH1C, were analyzed in smaller families with hearing impairment. Results: In the 45-member extended family, the critical chromosomal region mapped to 2p24-p22.The c.2122C>T (p.R708X) mutation in OTOF in 2p24-p22was identified as being the causal change. Linkage to 2p24-p22 locus was not observed in a particular branch of this extended family. Analysis of seven known deafness-causing genes in this branch revealed a mutation, c.254T>A (p.V85D), in CLDN14. Among seven small families unrelated to the 45-member extended family, hearing loss was attributable to p.R708X in OTOF in three families and to p.V85D in CLDN14 in one family; a new mutation c.1668T>A (p.Y556X) SLC26A4 was identified in two families and the causative change could not be identified in one family. Interpretation & conclusions: This study suggested considerable genetic heterogeneity in the causation of hearing loss in Dhadkai. Recessive mutations were observed in at least three genes causing hearing loss: OTOF (p.R708X), SLC26A4 (p.Y556X) and CLDN14 (p.V85D). Mutation p.R708X appeared to be the major cause of hearing impairment in Dhadkai.

RESUMO

INTRODUCTION: The present study evaluated the psychometric properties of the Arabic translation of the Mukbang Addiction Scale (MAS) among Arabic-speaking adults from the general population. Specifically, it aimed to assess the factorial structure through a confirmatory factor analysis, determine the composite reliability through Cronbach alpha and McDonald's omega scores, assess gender invariance, and evaluate the convergent validity by examining its correlation to eating addiction and psychological distress. METHODS: A total of 370 individuals with a mean age of 21.94 ± 2.29 years participated in this study, which was conducted using an online platform. The participants were surveyed on demographic information, mukbang addiction, food addiction, and psychological distress. Translation was conducted using the forward and backward technique. RESULTS: The findings demonstrated excellent internal consistency of the Arabic MAS (McDonald's omega coefficient = 0.93). Confirmatory factor analyses validated the one-factor structure of the scale, while establishing measurement invariance across sex at the configural, metric, and scalar levels. No sex differences were observed in the Mukbang addiction levels. Lastly, the MAS scores were significantly and positively correlated with food addiction and psychological distress, supporting their convergent validity. CONCLUSION: The current research provides evidence supporting the reliability and validity of the Arabic version of the MAS as a self-report method for assessing addictive Mukbang watching. While further validations are needed to corroborate the present findings, this measure can be effectively utilized across different fields, including schools, mental health centers, and researchers aiming to understand this global phenomenon. Mukbang refers to individuals or hosts consuming large quantities of food while interacting with their audiences through recorded video or a live stream. The Mukbang phenomenon has gained substantial popularity among young individuals over the past years, rising concerns about its potential impact on their eating habits and health, especially when overconsumed. Overconsumption of mukbang content, or Mukbang addiction, aligns with the core features of addiction, including compulsive engagement, tolerance, and withdrawal symptoms, making it comparable to other addictive behaviors. Mukbang addiction can lead to detrimental effects on mental and physical health, including neglect of balanced nutrition, disordered eating habits, obesity, feelings of guilt, shame, poor self-esteem, distorted self-images, body dissatisfaction, heightened anxiety or depression, and social isolation. Given these significant impacts, valid and reliable tools are crucial to enable an accurate assessment of Mukbang addiction. This study proposes to translate, adapt and examine the psychometric properties of the Mukbang Addiction Scale (MAS) in a sample of Arabic-speaking individuals from the general population. Findings showed that the six MAS items loaded on a single factor with strong internal consistency and good convergent validity, preliminarily indicating its potential validity and reliability for assessing addictive mukbang-watching among Arabic-speaking individuals.

RESUMO

BACKGROUNDS: Thyroid hormones play an important physiological role in human metabolism. Erythrocyte abnormalities are frequently associated with thyroid disorder. However, they are rarely investigated and related to the subclinical and primary hypothyroidism in Kashmiri Patients. In this study an attempt was made to study hematological parameters in untreated and treated subclinical hypothyroidism and primary hypothyroidism patients. METHODS: This retrospective study included 600 subjects, among which were untreated subclinical hypothyroid (n=110), treated subclinical hypothyroid (n=110), untreated primary hypothyroid (n=100), treated primary hypothyroid (n=100) and euthyroid (n=180). This study was carried out at Department of Biochemistry, Government Medical College Srinagar. The hematological parameters and thyroid profile of the subjects were assessed by the Sysmex (Italy) and ECLIA (Germany) 2010 automatic analyzer. Mean, standard deviation (SD), analysis of variance (Two-way ANOVA), and multiple comparisons were used to report our results, with p<0.05 or p<0.01 considered as statistically significant. RESULTS: In this study group we compared the hematological parameters in these groups, untreated subclinical hypothyroid, treated subclinical hypothyroid, untreated primary hypothyroid, treated primary hypothyroid and euthyroid. We found that hematological parameters like Hb, RBC, MCV, HCT, RDW,RBC% were significantly increased in untreated subclinical hypothyroidism and untreated primary hypothyroidsm, with the p value being less than 0.05 whereas, in treated SCH & Pr. Hypothyroid, results were insignificant. The results reported in these groups as mean±SD, were statistically tested by ANOVA and multiple comparison tests. In untreated subclinical hypothyroid the values were: Hb (10.83±1.33 g/dl), RBC (4.21±0.66 10(6)/µl), MCV (84.56±6.84 fL), HCT (38.5±2.2%), RDW (17.91±2.37 fL), RBC% (84.36±13.2%) and in untreated primary hypothyroid, Hb (10.73±0.86 g/dl), RBC (4.63±0.51 10(6)/µl), MCV (83.34±6.92 fL), HCT (38.6±2.6%), RDW (14.93±5.47 fL), RBC% (92.63±10.30%) suggesting that these patients were at risk of anemia and other erythrocyte abnormalities. MCV is an inexpensive approach to study the types of anemia and explore related information like production, destruction, loss and morphological changes of RBC'S. CONCLUSION: The thyroid dysfunction is frequently associated with anemia in subclinical hypothyroidism and primary hypothyroidism. Subclinical hypothyroidism (SCH) is associated with serious complications. Substantial numbers of patients with the risk of SCH could be getting converted into primary hypothyroidism. Such conditions should be identified and corrected. On the other hand, their presence could move to a thyroid dysfunction, allowing its early management.

RESUMO

The Duffy Antigen Receptor for Chemokines (DARC)-null trait, common among persons of African descent and associated with lower absolute neutrophil counts (ANCs), may be linked to increased risk to certain infections including HIV-1 but the underlying causes are poorly understood. We hypothesized that DARC-null-linked neutropenia may negatively impact neutrophil immunoregulatory modulation of other immune cells such as natural killer (NK) and CD8+ T cells leading to altered phenotype, functionality and homeostatic activity of these immune cells. HIV-1 uninfected (n = 20) and HIV-1 chronically infected (n = 19) participants were assessed using multi-parametric flow cytometry to determine NK and CD8+ T cell counts, phenotypic profiles, and cytokine production and degranulation. Annexin V and carboxyfluorescein succinimidyl ester (CFSE) staining were used to examine NK cell survival and NK cell and CD8+ T cell proliferation respectively. Participants were genotyped for the DARC-null polymorphism using allelic discrimination assays and ANCs were measured by full blood count. In HIV uninfected individuals, a reduction of total NK cell counts was noted in the absence of DARC and this correlated with lower ANCs. HIV uninfected DARC-null subjects displayed a less mature NK cell phenotype. However, this did not translate to differences in NK cell activation or effector functionality by DARC state. Whilst HIV-1 infected subjects displayed NK cell profiling that is typical of HIV infection, no differences were noted upon DARC stratification. Similarly, CD8+ T cells from HIV infected individuals displayed phenotypic and functional modulation that is characteristic of HIV infection, but profiling was unaffected by the DARC-null variant irrespective of HIV status. Overall, the data suggests that the DARC-null polymorphism and lower ANCs does not impede downstream cytolytic cell priming and functionality.
