Background and ObjectiveSeveral studies highlight the widespread prevalence of dental health problems within the Saudi population. To effectively develop public health strategies, it is vital to assess oral health knowledge, attitudes, and behaviours at a population level. This study aimed to examine these three domains among adults aged 18 and older residing in Al-Kharj, Saudi Arabia.MethodsA cross-sectional survey was conducted in 2024, involving a sample of adult visitors at shopping malls and public parks in Al-Kharj. Data were gathered using a validated, self-administered, structured questionnaire addressing knowledge, attitudes, and behaviours related to oral health.ResultsThe study included 367 participants aged 18 years and above. Among them, 90.2% were aware of the link between tobacco use and oral cancer, and 89.1% held favourable views regarding the use of fluoridated toothpaste to prevent cavities. However, only 55.6% brushed their teeth twice daily, and just 44.7% routinely visited a dentist. Women exhibited significantly better knowledge than men (p = 0.0001), older individuals had greater knowledge than younger ones (p = 0.004), and participants with a monthly income above 10,000 SAR scored higher on oral health knowledge (p = 0.003).ConclusionAlthough many respondents demonstrated good oral health knowledge, fewer than half maintained positive attitudes and practices necessary for proper oral care.

Background: Children are the foundation of a nation, and those in rural areas and lower socio-economic groups are vulnerable to malnutrition. This study aimed to evaluate and compare the nutritional status of preschool children and the socio-demographic factors affecting their growth in urban and rural Anganwadi centers (AWCs) of Davangere district. Methods: An observational, descriptive, cross-sectional survey was conducted in year May 2023 to October 2024 in both urban and rural AWCs of the Davanagere district. A total of 120 children aged 3-5years children were selected using multistage sampling and were screened using anthropometric measurements such as height, weight and mid upper arm circumference. Socio-demographic information was collected using self-structured questionnaire. Data were analyzed using SPSS v20 with p<0.05. Descriptive statistics and chi-square tests assessed associations between nutritional status and dichotomized sociodemographic variables. Results: In urban areas, 10% of children had moderate underweight and 5% had severe underweight, moderate stunting and severe stunting each, and 11.6% and 1.6% had moderate wasting and severe wasting respectively; whereas in rural areas, 6.6% had moderate underweight and 13.3% had severe underweight, 16.6% had moderate stunting and 5% had severe stunting, and 15% had moderate wasting with 5% showing severe wasting. Malnutrition was found to be associated with factors such as age of mother at marriage, family type, birth weight, breastfeeding practice, colostrum given and economic status of family. Conclusions: Malnutrition exists in both settings, driven by maternal and socio-economic factors, warranting targeted interventions.

With better surgery and chemotherapeutic agents, borderline resectable or locally advanced pancreatobiliary tumours are being treated with curative intent. This study presents real-world evidence of porto-mesenteric vein resections (PVR) with pancreatectomy and generates predictive nomograms for postoperative mortality (POM) and major complications (MC). A retrospective multicentre study, including 11 high-volume centres, evaluated patients undergoing PVR. Factors affecting 90-day POM and MC (Clavien-Dindo grades ≥ 3a) were assessed, and predictive nomograms were generated. Overall survival (OS) and disease-free survival (DFS) were estimated for patients with pancreatic ductal adenocarcinoma (PDAC). Cox regression analysis was performed to ascertain factors affecting OS and DFS. Among 389 patients, POM was 6.4%, and MCs were 32.6%. Charlson comorbidity index > 4, preoperative biliary drainage, preoperative radiotherapy (PRT), segmental PVR, and additional organ resection (AOR) were predictive of POM. The independent predictors of MCs were American Society of Anesthesiologists status 3/4, PRT, and AOR. The generated model had an area under the curve (AUC) of 0.757, cutoff > 1.79 to predict POM, and AUC of 0.669, cutoff > 0.678 for MCs. In the 263 patients with PDAC, the median OS was 25.01 months (95% confidence interval [CI] 21.9-28.11), and DFS was 16.72 months (95% CI 14.56-18.89). Perineural invasion, segmental PVR, and margin positivity predicted worse survival, while completing multi-modality treatment was protective. The POM and MCs of PVR with pancreatectomy were at par with the world standards. The generated predictive nomograms for POM and MC revealed a good predictive potential. In patients with PDAC, completion of multimodality treatment offers better long-term survival.

The present work describes an investigation of mixed convective nanofluid flow in the presence of a porous medium on a sheet surface under radiation and mass transpiration conditions. Suitable similarity transformations are applied to convert the governing partial differential equations (PDEs) into ordinary differential equations (ODEs). Later, the precise yielding of the domain was confirmed by the resulting ODEs. To improve thermal efficiency, silver nanoparticles are dispersed throughout the fluid flow. The primary focus of the current study is on accurate solutions for two-Dimensional nanofluid flow and the impact of several factors on velocity and temperature profiles, including mass transpiration, thermal radiation, inverse Darcy number, and volume fraction. The result shows a single stretching solution.

The primary factors affecting people's choices with investments are their comprehension of ‎investments and their comfort with risk. This research assesses investment knowledge and risk ‎appetite among respondents with varied demographic characteristics. The research focuses ‎particularly on the relationship between investment literacy as well as risk tolerance, along ‎with their combined effect on the investment choices of students and additionally working ‎people aged 18-28.‎The study collected responses from 208 participants via an online survey. The study assessed ‎participants’ investment literacy and risk preferences using a validated scale, and particular ‎statistical analyses, such as Mann-Whitney U, Kruskal-Wallis, and logistic regression, were ‎applied. The findings indicate that while investment literacy improves financial awareness, it ‎does not substantially influence people’s willingness to engage in high-risk investments. ‎People who can take on greater risk are 1.9 times more likely to put money into assets that ‎have more risk. Although gender influences risk tolerance, it does not directly affect ‎investment choices.‎The study’s results stress that investment literacy alone does not increase risk perception. ‎Instead, other external factors are im-portant to address. These findings stress the need for ‎targeted investment literacy programs that carefully improve financial knowledge, integrating ‎many behavioral understandings to support thoroughly well-informed decision-making. This ‎study improves the broader comprehension of the psychological factors influencing ‎investment decisions, especially for younger investors‎.
