Objectives Lifetime DSM‐5 diagnoses generated by the lay‐administered Composite International Diagnostic Interview for DSM‐5 (CIDI) in the World Mental Health Qatar (WMHQ) study were compared to diagnoses based on blinded clinician‐administered reappraisal interviews. Methods Telephone follow‐up interviews used the non‐patient edition of the Structured Clinician Interview for DSM‐5 (SCID) oversampling respondents who screened positive for five diagnoses in the CIDI: major depressive episode, mania/hypomania, panic disorder, generalized anxiety disorder, and obsessive‐compulsive disorder. Concordance was also examined for a diagnoses of post‐traumatic stress disorder based on a short‐form versus full version of the PTSD Checklist for DSM‐5 (PCL‐5). Results Initial CIDI prevalence estimates differed significantly from the SCID for most diagnoses (χ12${\\chi }_{1}^{2}$  = 6.6–31.4, p = 0.010 < 0.001), but recalibration reduced most of these differences and led to consistent increases in individual‐level concordance (AU‐ROC) from 0.53–0.76 to 0.67–0.81. Recalibration of the short‐form PCL‐5 removed an initially significant difference in PTSD prevalence with the full PCL‐5 (from χ12${\\chi }_{1}^{2}$  = 610.5, p < 0.001 to χ12${\\chi }_{1}^{2}$  = 2.5, p = 0.110) while also increasing AU‐ROC from 0.76 to 0.81. Conclusions Recalibration resulted in valid diagnoses of common mental disorders in the Qatar National Mental Health Survey, but with inflated prevalence estimates for some disorders that need to be considered when interpreting results.

Although predatory publishers are increasingly recognized, universally accepted criteria for defining predatory journals are lacking. These journals challenge the scholarly community by blurring the line between legitimate and questionable publishing practices. Several lists and reports of predatory journals have been published, which offer valuable insights; however, they are not devoid of criticism. Beall's list, although criticized for its inclusion criteria, is currently managed anony-mously and updated infrequently. Cabells' list uses an extensive array of inclusion criteria, some of which are similar to those used in Beall's list. Several of these cri-teria are redundant and fail to detect predatory practices, and using all of them in evaluating a journal is seldom practicable. Kscien's list has emerged as a promising alternative for identifying predatory publishers or journals. However, it requires refinement, potentially through creating a distinct list supported by unequivocal evidence, such as accepting a fake manuscript (ascertained through a sting opera-tion). The present review seeks to catalyze research on identifying predatory jour-nals and publishers by comparing existing lists and suggesting new techniques for detecting predatory practices.

A novel derivative of ciprofloxacin (Cpx) was synthesized and characterized using various analytical techniques, including FT-IR spectroscopy, UV-Vis spectroscopy, TEM and SEM analysis, 1H NMR, 13C NMR, and HPLC analysis. The newly prepared Cpx derivative (Cpx-Drv) exhibited significantly enhanced antibacterial properties compared to Cpx itself. In particular, Cpx-Drv demonstrated a 51% increase in antibacterial activity against S. aureus and a 30% improvement against B. subtilis. It displayed potent inhibitory effects on topoisomerases II (DNA gyrase and topoisomerase IV) as potential molecular targets, with IC50 values of 6.754 and 1.913 µg/mL, respectively, in contrast to Cpx, which had IC50 values of 2.125 and 0.821 µg/mL, respectively. Docking studies further supported these findings, showing that Cpx-Drv exhibited stronger binding interactions with the gyrase enzyme (PDB ID: 2XCT) compared to the parent Cpx, with binding affinities of −10.3349 and −7.7506 kcal/mole, respectively.

Current malaria control and elimination strategies rely mainly on efficacious antimalarial drugs. However, drug resistance is a major threat facing malaria control programs. Determination of drug resistance molecular markers is useful in the monitoring and surveillance of malaria drug efficacy. This study aimed to determine the mutations and haplotypes frequencies of different genes linked with antimalarial drug resistance in certain areas in Sudan. A total of 226 dried blood spots (DBS) of microscopically diagnosed P. falciparum isolates were collected from Khartoum and three other areas in Sudan during 2015-2017. Plasmodium falciparum confirmation and multiplicity of infection was assessed using the Sanger's 101 SNPs-barcode and speciation was confirmed using regions of the parasite mitochondria. Molecular genotyping of drug resistance genes (Pfcrt, Pfmdr1, Pfdhfr, Pfdhps, exonuclease, Pfk13, parasite genetic background (PGB) (Pfarps10, ferredoxin, Pfcrt, Pfmdr2)) was also performed. All genotypes were generated by selective regions amplicon sequencing of the parasite genome using the Illumina MiSeq platform at the Wellcome Sanger Institute, UK then genotypes were translated into drug resistance haplotypes and species determination. In total 225 samples were confirmed to be P. falciparum. A higher proportion of multiplicity of infection was observed in Gezira (P<0.001) based on the Sanger 101 SNPs -barcode. The overall frequency of mutant haplotype Pfcrt 72-76 CVIET was 71.8%. For Pfmdr1, N86Y was detected in 53.6%, Y184F was observed in 88.1% and D1246Y was detected in 1.5% of the samples. The most frequently observed haplotype was YFD 47.4%. For Pfdhfr (codons 51, 59,108,164), the ICNI haplotype was the most frequent (80.7%) while for Pfdhps (codons 436, 437, 540, 581, 613) the (SGEAA) was most frequent haplotype (41%). The Quadruple mutation (dhfr N51I, S108N + dhps A437G, K540E) was the highest frequent combined mutation (33.9%). In Pfkelch13 gene, 18 non-synonymous mutations were detected, 7 of them were detected in other African countries. The most frequent Pfk13 mutation was E433D detected in four samples. All of the Pfk13 mutant alleles have not been reported to belong to mutations associated with delayed parasite clearance in Southeast Asia. PGB mutations were detected only in Pfcrt N326S\\I (46.3%) and Pfcrt I356T (8.2%). The exonuclease mutation was not detected. There was no significant variation in mutant haplotypes between study areas. There was high frequency of mutations in Pfcrt, Pfdhfr and Pfdhps in this study. These mutations are associated with chloroquine and sulfadoxine-pyrimethamine (SP) resistance. Many SNPs in Pfk13 not linked with delayed parasite clearance were observed. The exonuclease E415G mutation which is linked with piperaquine resistance was not reported.

Background Patients with beta‐thalassemia major are prone for developing cardiovascular complications. Early identification of patients at risk is important. B‐type natriuretic peptides such as brain natriuretic peptide (BNP) and N‐terminal pro‐BNP (NT‐proBNP) are sensitive indicators of cardiac dysfunction. This review synthesizes the existing evidence on the levels of B‐type natriuretic peptides in beta‐thalassemia major and their relationship with markers of cardiac dysfunction and other biomarkers. Methods A systematic review was conducted according to PRISMA guidelines. The search was performed in the PubMed, Web of Science, ScienceDirect, and World Health Organization Virtual Health Library Regional Portal. Pooled standardized mean differences (SMD) and correlation coefficients (r) with 95% confidence intervals (CI) were calculated to investigate the differences in B‐type natriuretic peptides values and their relationships with various biomarkers in beta‐thalassemia major. Results A total of 29 studies were selected for the systematic review. Of them, 27 were included in the meta‐analyses. Most of the included studies focused on investigating NT‐proBNP. The analyses revealed significantly higher NT‐proBNP and BNP values in patients with beta‐thalassemia major compared to healthy controls. For NT‐proBNP, the pooled effect size (SMD) was 1.37 (95% CI: 0.856–1.893, p < 0.001), and for BNP, it was 1.94 (95% CI: 0.665–3.220, p = 0.003). Meta‐analyses of correlations revealed that NT‐proBNP was significantly correlated with serum ferritin levels (r = 0.471, p = 0.006), E/E′ ratio (r = 0.528, p < 0.001), and patients age (r = 0.259, p = 0.004). Conclusion This systematic review provides evidence that beta‐thalassemia is associated with high levels of B‐type natriuretic peptides, which highlight the high risk of cardiovascular complications in this patient population. The significantly elevated levels of both molecules and their identified correlations emphasize clinical utility of them as markers of early myocardial stress and subclinical heart disease in beta‐thalassemia.

Artificial intelligence models, like ChatGPT, have the potential to revolutionize higher education when implemented properly. This study aimed to investigate the factors influencing university students’ attitudes and usage of ChatGPT in Arab countries. The survey instrument “TAME-ChatGPT” was administered to 2240 participants from Iraq, Kuwait, Egypt, Lebanon, and Jordan. Of those, 46.8% heard of ChatGPT, and 52.6% used it before the study. The results indicated that a positive attitude and usage of ChatGPT were determined by factors like ease of use, positive attitude towards technology, social influence, perceived usefulness, behavioral/cognitive influences, low perceived risks, and low anxiety. Confirmatory factor analysis indicated the adequacy of the “TAME-ChatGPT” constructs. Multivariate analysis demonstrated that the attitude towards ChatGPT usage was significantly influenced by country of residence, age, university type, and recent academic performance. This study validated “TAME-ChatGPT” as a useful tool for assessing ChatGPT adoption among university students. The successful integration of ChatGPT in higher education relies on the perceived ease of use, perceived usefulness, positive attitude towards technology, social influence, behavioral/cognitive elements, low anxiety, and minimal perceived risks. Policies for ChatGPT adoption in higher education should be tailored to individual contexts, considering the variations in student attitudes observed in this study.

Purpose Rhegmatogenous retinal detachment (RRD) is a sight-threatening condition requiring prompt surgical intervention. Various adjunctive techniques are employed to enhance subretinal fluid drainage and retinal reattachment. This study aimed to evaluate the outcomes of perfluorocarbon liquid (PFCL) versus posterior retinotomy (PR) during pars plana vitrectomy (PPV) for RRD, focusing on anatomical success, visual acuity, intraocular pressure (IOP), and complications. Methods This is a prospective randomized controlled trial that included 58 eyes with RRD, divided into Group A (PFCL, n  = 29) and Group B (PR, n  = 29). Preoperative assessments included best-corrected visual acuity (BCVA), IOP, axial length, lens status, macula status, and PVR grade. Outcomes were evaluated at 1 week, 1 month, 2 months, and 3 months postoperatively. Primary outcomes included retinal reattachment rates and the number of operations; secondary outcomes included BCVA, IOP changes, complications like cataract development, retinal redetachment, epiretinal membrane (ERM) formation, and single-surgery success. Results Retinal reattachment rates were comparable (76% in Group A vs. 66% in Group B, p  = 0.387), as well as the number of operations ( p  = 0.375). Moreover, BCVA improved significantly in both groups ( p  < 0.05), with no intergroup differences. IOP increased postoperatively in both groups ( p  < 0.001), with no significant differences. No differences were observed in cataract formation or retinal redetachment. However, ERM incidence was significantly higher in the PR group (27% vs. 11%, p  = 0.049). Conclusion PFCL and PR are effective for RRD repair, with similar anatomical and visual outcomes. However, PFCL may reduce ERM risk, making it preferable in certain cases. These findings guide surgical decision-making and highlight the need for further research. Trial registration The study was retrospectively registered at ClinicalTrials.gov (NCT06919211) on April 4, 2025.

The widespread misconception that tonsillectomy leads to a decrease in immunity may lead to fear and avoidance of the operation. This can result in a deterioration of the situation, such as sleep-related breathing issues, frequent infections, and an increase in complications. The current research was conducted to assess the awareness and perception with respect to the impact of tonsillectomy on the immune system and to assess the awareness and perception of the relationship between autoimmune diseases and tonsillectomy. This 6-month descriptive cross-sectional online questionnaire survey was conducted among individuals who were 18 years and above living in Abha city, Saudi Arabia. Out of the 800 study subjects, 104 (13%) had undergone tonsillectomy. Statistically significant associations were found between age group, education, income, and occupation among those who had undergone tonsillectomy. Multivariate logistic regression analysis showed that ages 18–30 years and 31–40 years (OR: 2.36, 95% CI: 1.18–4.71, and OR: 1.46, 95% CI: 0.53–3.97) and education levels of high school, bachelors, and above (OR: 8.30, 95% CI: 3.05–22.58 and OR: 10.89, 95% CI: 4.23–28.05) were found to be associated with tonsillectomy status of the subjects. On the contrary, income levels of 5000–9000 and >9000 (OR: 0.65, 95% CI: 0.36–1.17 and OR: 0.78, 95%CI: 0.42–1.42) and male gender (OR: 0.79, 95% CI: 0.52–1.19) were found to be associated with non-tonsillectomy status of subjects. Almost 36% of study subjects thought that tonsillectomy affects immunity. Only 18% of study subjects thought that there is a relationship between tonsillectomy and autoimmune diseases. About one-third of the respondents had received this information from community members and social media. A small number of study subjects relied on public awareness programs. Therefore, social media can play a vital role in the community to remove misconceptions regarding tonsillectomy and its effect on immunity and autoimmune disease. Further educational interventional studies are required to see the correction to the public perception of tonsillectomy and its effect on immunity and autoimmune diseases.

Background The burden of carbapenem resistance is not well studied in the Middle East. We aimed to describe the molecular epidemiology and outcome of carbapenem-resistant Enterobacterales (CRE) infections from several Saudi Arabian Centers. Methods This is a multicenter prospective cohort study conducted over a 28-month period. Patients older than 14 years of age with a positive CRE Escherichia coli or Klebsiella pneumoniae culture and a clinically established infection were included in this study. Univariate and multivariable logistic models were constructed to assess the relationship between the outcome of 30-day all-cause mortality and possible continuous and categorical predictor variables. Results A total of 189 patients were included. The median patient age was 62.8 years and 54.0% were male. The most common CRE infections were nosocomial pneumonia (23.8%) and complicated urinary tract infection (23.8%) and 77 patients (40.7%) had CRE bacteremia. OXA-48 was the most prevalent gene (69.3%). While 100 patients (52.9%) had a clinical cure, 57 patients (30.2%) had died within 30 days and 23 patients (12.2%) relapsed. Univariate analysis to predict 30-day mortality revealed that the following variables are associated with mortality: older age, high Charlson comorbidity index, increased Pitt bacteremia score, nosocomial pneumonia, CRE bacteremia and diabetes mellitus. In multivariable analysis, CRE bacteremia remained as an independent predictor of 30 day all-cause mortality [AOR and 95% CI = 2.81(1.26–6.24), p = 0.01]. Conclusions These data highlight the molecular epidemiology and outcomes of CRE infection in Saudi Arabia and will inform future studies to address preventive and management interventions.

The paranasal sinuses are hollowed, air-filled cavities surrounding the nasal cavity. Many pathological processes affect the sinuses, but inflammatory conditions are the commonest, even in asymptomatic patients who undergo head imaging for other indications showing one or more abnormalities of the sinuses. Our research aims to determine the prevalence of incidental paranasal sinuses abnormalities seen among patients who undergo head CT scanning. In addition, it provides baseline information for further investigations required. The study was designed to evaluate all patients who underwent head CT scanning for any reason unrelated to paranasal sinuses abnormalities. 1849 cases were selected and retrospectively analyzed from the elective and emergency CT in the last nine months, from August 2020 to April 2021. In order to meet the inclusion criteria, indications for imaging must not be sinus-related. The study was conducted on 1849 cases who had undergone head CT scans for pathology, 1204 (65%) were male and 645 (35%) were female. Abnormalities of the sinuses were found in about 617 (33%) of all patients, with a higher rate in males (22.23%) than females (11.14%). In addition, these abnormalities were found in younger patients at a higher rate than in middle and old ages 19.74%, 7.19%, and 6.44%, respectively. Our findings revealed that the prevalence of paranasal sinuses abnormalities in asymptomatic Saudi patients was high (33%). Most of the affected sinuses were the maxillary. The male patients were more affected than females in all findings.
