Background: In orthodontic treatment, it is most important to assess the patient's perspective of malocclusion because these perceptions are fundamental to determining the patient's demands and level of treatment satisfaction. This study was done to assess the knowledge and perception of residents of the Aljouf Region of Saudi Arabia seeking orthodontic treatment. Furthermore, we determined the factors associated with the patients' knowledge and perception of orthodontic treatment. Methods: This cross-sectional study was conducted using a pre-tested and validated questionnaire among patients seeking orthodontic treatment who were registered at King Abdulaziz Hospital, Sakaka, and primary health centers. We identified the associated factors using binomial logistic regression analysis. Finally, we applied Spearman's correlation test to identify the correlation between knowledge and perception. Results: A total of 282 individuals participated in the current study, of which 53.3% were female and 46.1% were male. About one-third (36.9%) of patients had a low level of knowledge, 35.5% had a medium level of knowledge, and 27.7% had a high level of knowledge regarding orthodontic treatment. A total of 20.6% had low perceptions, 42.9% had medium perceptions, and 36.5% had high perceptions of orthodontic care. A significant correlation was found between age and gender, knowledge (p = 0.001), and perception (p = 0.040). Moreover, we observed a positive correlation between knowledge and perception (Spearman's rho = 0.297, p = 0.001). Conclusion: People in Aljouf have poor knowledge and medium perception regarding orthodontic treatment. We recommend that the concerned authorities make a health educational plan for the patients seeking orthodontic treatment. [ABSTRACT FROM AUTHOR]

Drug resistance (DR) to antituberculosis drugs is a growing global problem that threatens the successful control of tuberculosis (TB) globally and within the Gulf Cooperation Council (GCC). In the GCC, TB remains a major public health issue. Understanding the prevalence and patterns of drug resistance to antituberculosis drugs is crucial for developing effective prevention and treatment strategies. Hence, the present systematic review is aimed at assessing the prevalence, pattern, and risk factors of drug-resistant TB (DR-TB) in GCC countries. We conducted this systematic review adhering to the guidelines outlined in the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020 Statement. Using the relevant keywords in the major databases, we included peer-reviewed articles that were published from 01 January 2014 and onwards in English language journals. The prevalence and patterns of DR-TB levels in different countries were different. Isoniazid monoresistance was the most commonly found type of resistance, with varying degrees of prevalence of multidrug-resistant tuberculosis (MDR-TB). Risk factors for DR-TB included diabetes mellitus, past TB treatment, younger age, female gender, and renal failure. There was a positive correlation between expatriate status and DR-TB. Collaborative actions by relevant stakeholders are essential to implement evidence-based interventions that reduce the DR-TB burden and improve overall community health. Ongoing research and surveillance activities are necessary for monitoring patterns, identifying new risk factors, and providing focused interventions to lessen the threat of DR-TB on public health in GCC countries.
