Abstract	Abstract Background Several denture base materials have evolved over the years. Beginning with metal and ending up with various types of acrylic materials in order to have a biocompatible, antimicrobial denture base. A flexible acrylic resin, such as Polyamides, has been introduced to address the drawbacks of heat-cured PMMA resin. This study was conducted to examine the water solubility and water sorption of flexible thermoplastic polyamides (Valplast) and two types of conventional heat-cured acrylic resin (PMMA) (Acrostone, Vertex). Methods Specimens of thermoplastic polyamides and two types of conventional PMMA (Acrostone, Vertex) resin were manufactured and used in the current investigation in accordance with manufacturer instructions. A total of 45 specimens were milled into discs with a diameter of 50.0 mm diameter, 5.0 mm thick. To ascertain conformity with ADA Standard No. 12, water solubility and water sorption were measured. Results All items complied with ADA regulations for water solubility and sorption. Flexible thermoplastic polyamide displayed less water solubility, and water sorption than heat-cured PMMA. Acrostone showed the higher water solubility, sorption followed by Vertex heat cure acrylic resin both heat cured showed significant higher water solubility than polyamides Valplast). Conclusions Within the limitations of this in vitro experiment, heat cure PMMA resin demonstrated significantly greater water solubility and water sorption when compared to thermoplastic polyamides.

Abstract	Background: Irritable bowel syndrome (IBS) is a very common gastrointestinal disorder encountered in clinical practice. In this study, we estimated the prevalence of isolated IBS and its associated demographic factors among the adult population in the Kingdom of Bahrain. Methods: A cross-sectional study was conducted targeting adults in Bahrain aged 18 years and above. Individuals with a prior diagnosis of any bowel ailment were excluded. Data was acquired via a self-administered questionnaire. IBS-specific questions were derived from the validated Rome IV diagnostic questionnaire for adults. The scoring methodology inherent to this questionnaire was used for the diagnosis of IBS. The data collection process remained anonymous. Data was compiled using Excel spreadsheets, and the Statistical Package for Social Sciences (SPSS) was employed for analytical purposes. Associations between IBS and demographical or behavioral characteristics were explored using the Chi-square test. Results: The prevalence of isolated IBS, adopting the Rome IV criteria, was 156 (18.3%) and IBS-M (mixed) type was 40 (38.1%) of these. IBS was predominantly higher among females compared to males (340 vs 235; 22.6% vs 11.9%). The majority of IBS cases (121, 21%) were in the 41-50 age group. A statistically significant association has been demonstrated between IBS and GERD using Pearson's chi-squared test (p-value = 0.000). Similarly, it was linked to indigestion (p-value = 0.00). Conclusions: Although the percentage appeared to be significantly higher than the global prevalence of 4% (using Rome IV criteria), our findings were equivalent to the reports conducted in the Middle East region. Integrating holistic patient assessments, including quality of life metrics, along with anxiety, depression, and vitamin D deficiency, will further enhance the understanding of IBS in Bahrain and its impact on the patients and the health services utilization.

Abstract	Background: Attention deficit hyperactivity disorder (ADHD) is a serious public health problem. Diet-focused approaches and physical exercise can be used to complement other ADHD management techniques. Objective: To determine the prevalence of ADHD symptoms among preschoolers in nursery schools and to evaluate the educational interventions toward nutrition and physical exercise in mothers and their preschoolers with ADHD symptoms. Research methodology: A two-phase sampling method was employed. First, a cross-sectional survey was conducted to determine the prevalence of ADHD symptoms in four nursery schools (400 preschoolers aged between 3 and 6 years). Second, an intervention study (a quasi-experimental research design with one group completing the pre-test and the post-test) was performed on 36 preschoolers having ADHD symptoms and their mothers by using the educational intervention for mothers and photos and games about nutrition and physical exercise for the preschoolers with ADHD; mothers of four children out of the 40 refused to participate in the study. Data were analyzed using SPSS version 20. The paired t-test was used to determine significant differences between the groups. Differences were considered significant at P < 0.05. Results: Of the 400 preschoolers, 10% had high ADHD symptoms. The mean score of mothers' knowledge of nutrition and physical exercise improved after the implementation of the program (p = 0.01). In addition, preschoolers with ADHD enjoyed the session with photos and games (p = 0.01). Conclusions and implications: Educational intervention significantly improved the knowledge of the mothers. Moreover, preschoolers with ADHD symptoms enjoyed the session with photos and games. This intervention appears to be feasible and promising for further investigation of its effects.

Abstract	Pharmaceutically active compounds (PhACs) represent an emerging class of contaminants. With a potential to negatively impact human health and the ecosystem, existence of pharmaceuticals in the aquatic systems is becoming a worrying concern. Antibiotics is a major class of PhACs and their existence in wastewater signifies a health risk on the long run. With the purpose of competently removing antibiotics from wastewater, cost-effective, and copiously available waste-derived adsorbents were structured. In this study, mango seeds kernel (MSK), both as a pristine biochar (Py-MSK) and as a nano-ceria-laden (Ce-Py-MSK) were applied for the remediation of rifampicin (RIFM) and tigecycline (TIGC). To save time and resources, adsorption experiments were managed using a multivariate-based scheme executing the fractional factorial design (FrFD). Percentage removal (%R) of both antibiotics was exploited in terms of four variables: pH, adsorbent dosage, initial drug concentration, and contact time. Preliminary experiments showed that Ce-Py-MSK has higher adsorption efficiency for both RIFM and TIGC compared to Py-MSK. The %R was 92.36% for RIFM compared to 90.13% for TIGC. With the purpose of comprehending the adsorption process, structural elucidation of both sorbents was performed using FT-IR, SEM, TEM, EDX, and XRD analyses which confirmed the decoration of the adsorbent surface with the nano-ceria. BET analysis revealed that Ce-Py-MSK has a higher surface area (33.83 m

Abstract	Deficient water, sanitation, and hygiene (WASH) significantly account for a high burden of disease across the globe. Lebanon, an Eastern Mediterranean lower-middle-income country with a polluted environment, a fragmented healthcare system, and an ongoing severe economic crisis, faces serious challenges in sustaining safe water supplies, especially in vulnerable communities, while also hosting the world highest refugee population per capita. This study aimed to examine the mutagenicity, and the estrogenic and androgenic activities of water supplies, across both a Palestinian refugee camp and a Syrian informal settlement. Water samples were collected from two targeted camps in Dbayeh and Choueifat, North and South of the Capital City Beirut, respectively, between the months of September and October 2022. Microbial and physicochemical properties of samples were determined, including fecal contamination, total dissolved solids, and various minerals and salts. Organic pollutants were extracted using pre-packed solid phase extraction (SPE) columns, and then mutagenicity of extracts was examined using the Ames test in two Salmonella typhi bacterial strains. The estrogenic and androgenic activities of extracts were assessed using the yeast estrogen and androgen screen tests assays (YES/YAS). Results show excessive levels of total coliforms and total dissolved solids (TDS) in samples from both sites. In addition, the water supply from the Dbayeh Palestinian refugee camp is mutagenic, while the water supply from the Choueifat Syrian informal settlement shows anti-androgen activity. Our findings provide valuable WASH baseline data in two major vulnerable communities in Lebanon, and highlight the importance of a water toxicity testing approach concomitant with a water safety plan, based on a holistic strategy that covers all stages of the water supply chain.

Abstract	Diagnosing Autism spectrum disorder (ASD) is a challenging task for clinicians due to the inconsistencies in existing medical tests. The Internet of things (IoT) has been used in several medical applications to realize advancements in the healthcare industry. Using machine learning in tandem IoT can enhance the monitoring and detection of ASD. To date, most ASD studies have relied primarily on the operational connectivity and structural metrics of fMRI data processing while neglecting the temporal dynamics components. Our research proposes Progressive Fourier Transform (PFT), a novel time-frequency decomposition, together with a Convolutional Neural Network (CNN), as a preferred alternative to available ASD detection systems. We use the Autism Brain Imaging Data Exchange dataset for model validation, demonstrating better results of the proposed PFT model compared to the existing models, including an increase in accuracy to 96.7%. These results show that the proposed technique is capable of analyzing rs-fMRI data from different brain diseases of the same type.
