Abstract Introduction This systematic review explores the hypothesis that various lipid categories and lipid metabolism-related genomic variations link to mental disorders, seeking potential clinically useful markers. Methods We searched PubMed, Scopus, and PsycInfo databases until October 12th, 2024, using terms related to lipidomics, lipid-related genomics, and different mental disorders, i.e., Major Depressive Disorder (MDD), Bipolar Disorder (BD), Schizophrenia (SCZ), and Obsessive–Compulsive Disorder (OCD). Eligible studies were assessed. Extracted data included author, year, methodology, outcomes, genes, and lipids linked to disorders. Bias and evidence certainty were evaluated. The systematic review adhered to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and a registered protocol (PROSPERO: CRD42023438862). Results A total of 27 studies were included. SCZ showed alterations in 77 lipids, including triglycerides (TG), ceramides, and phosphatidylcholine, while MDD and BD exhibited 97 and 47 altered lipids, respectively, with overlap among disorders. Shared genes, such as ABCA13, DGKZ, and FADS, and pathways involving inflammation, lipid metabolism, and mitochondrial function were identified. OCD was associated with sphingolipid signaling and peroxisomal metabolism. Discussion Lipid signatures in MDD, BD, and SCZ shed light on underlying processes. Further research is needed to validate biomarkers and refine their clinical applications in precision psychiatry.

Abstract This paper presents the design, development, and evaluation of Just-in-time Quiz (JiTQ)—a novel tool that integrates real-time attendance tracking with synchronous formative assessment. Motivated by the need to streamline classroom management and enhance student engagement, JiTQ enables QR-based participation, automated attendance recording, and immediate feedback through live quizzes. Developed as a native Moodle plugin, it leverages the Moodle API for seamless integration and accessibility across devices. The system was deployed during the 2024–25 academic year at Oman Dental College across undergraduate dentistry modules. Faculty received training and support resources, and the tool was actively used in regular sessions. Data from system logs indicate strong adoption: 651 quiz instances were recorded across 67 modules, generating over 60,000 student attempts from 476 unique users. Student and faculty feedback, gathered through surveys, highlighted the tool’s usability, impact on engagement, and potential for data-driven teaching. JiTQ demonstrates how combining attendance and just-in-time assessment can lead to improved instructional efficiency, higher student attentiveness, and enhanced learning outcomes. Its integration into daily teaching practice offers a scalable model for real-time classroom interaction and ongoing learner evaluation. Future enhancements aim to expand its analytics capabilities and support adaptive learning strategies.

The purpose of this paper is to share a detailed description of the design, development process, implementation, and planned evaluation of an IPE model connecting Nutrition and Dentistry programs at the University of Illinois Chicago (UIC). The program sought to address educational gaps and enhance collaborative learning among healthcare students.Methods: This IPE teaching activity was guided by the World Health Organization’s IPE guidelines and the Core Competencies for Interprofessional Collaborative Practice. The process involved the formulation of educational model, preparation of students and implementation of three IPE sessions as a collaborative effort between dental and nutrition faculty. Teaching strategies included small group discussions and case studies to foster inclusive learning. The IPE teaching activity evaluation presented in this article corresponds to traditional pretest-posttest (TPP) design, using a validated IPE tool SPICE-R2. Qualitative reflective feedback was collected to understand the program’s impact on professional confidence and holistic care delivery. Quantitative analysis was conducted using T-test for pre and post SPICE-R2 scores and thematic analysis to analyze the qualitative reflections.Results: Pre and post SPICE-R2 scores analysis showed significant improvements in overall students’. For the domains of interprofessional teamwork, understanding of roles, and patient care outcomes, high significance was noted. Qualitative feedback highlighted the program’s success in enhancing professional confidence and promoting patient-centered care. Students valued the diverse and dynamic teaching strategies employed. Challenges included space limitations and initial role clarification difficulties.Conclusion: This IPE model effectively improved students’ perception towards interprofessional collaborative teamwork, roles and patient outcomes. Recommendations for future iterations include expanding the program to multiple institutions, varied learning environments, and long-term assessments to ensure sustained impact. These findings underscore the importance of Interprofessional Education in preparing healthcare professionals for collaborative practice and improving patient care outcomes.Keywords: interprofessional education, curriculum development, dietary counseling, nutrition, dentistry, undergraduate dental education

Background and Objectives: Dental caries continues to be a major health concern for populations worldwide. In India, the prevalence is increasing at an alarming rate among child population. Assessing caries risk in children is more beneficial than treating the disease in terms of economic as well as public health outcomes. Hence, a study was conducted to assess caries risk in 13–15-year-old government and private schoolchildren in Guntur city using Cariogram model and to identify the particular risk factors that were most frequent among schoolchildren. Materials and Methods: A comparative cross-sectional study was conducted among government and private high schoolchildren in Guntur city. A total of 100 children aged 13–15 years were selected randomly. Data were obtained by means of questionnaire, intraoral examination, and salivary analysis. The information obtained was entered into Cariogram model to calculate the “percentage chance to avoid caries.” Results: Of the total 100 schoolchildren, 43 were boys and 57 were girls. The government schoolchildren had a higher mean decayed, missing, and filled teeth (1.50 ± 1.669) compared to the private schoolchildren (0.40 ± 0.833), which was significant. The mean chance to avoid caries was significantly higher in private schoolchildren (70.56%) compared to government schoolchildren (57.32%). Conclusion: Diet incorporates a major role in assessing caries risk in the present study including its content and frequency. The Cariogram model could find out the factors contributing to the development of caries in the individual and help to plan targeted preventive actions.
The novel coronavirus (COVID-19) pandemic has become a real challenge for healthcare providers around the world and has significantly affected the dental professionals in practices, universities and research institutions. The aim of this article was to review the available literature on the relevant aspects of dentistry in relation to COVID-19 and to discuss potential impacts of COVID-19 outbreak on clinical dentistry, dental education and research. Although the coronavirus pandemic has caused many difficulties for provision of clinical dentistry, there would be an opportunity for the dental educators to modernize their teaching approaches using novel digital concepts in teaching of clinical skills and by enhancement of online communication and learning platforms. This pandemic has also highlighted some of the major gaps in dental research and the need for new relevant knowledge to manage the current crisis and minimize the impact of such outbreaks on dentistry in the future. In conclusion, COVID-19 has had many immediate complications for dentistry of which some may have further long-term impacts on clinical practice, dental education and dental research.

In the United States, current endovascular repair of proximal arch pathology is limited by patient anatomy, and the availability of Food and Drug Administration (FDA) approved devices. Through the first FDA-authorized Compassionate Use (CU) of a modified scalloped Terumo RelayPro Plus, we describe an endovascular repair of a type Ia endoleak, in a patient with bovine arch anatomy, with distal arch aneurysmal degeneration after an open type A dissection repair and failed conventional TEVAR. Further investigation is warranted to determine whether the increased effective seal zone provided by a scalloped thoracic endograft decreased the risk of type Ia endoleak and subsequent dissection-related aneurysmal degeneration in the aortic arch.

Solanum torvum is one of the plants mentioned in “Kitab Al-Tibb Pontianak”, a historical medical manuscript which encompasses many traditional healings of Malay people for various ailments including of hypertension. This systematic review involves searching within Science Direct, SCOPUS, and PUBMED databases with the aim to find scientific evidences purporting this traditional claim. The keywords such as anti-hypertensive, angiotensin-converting enzyme (ACE) inhibitor, blood pressure, diuretic, vasodilation, Solanum torvum, and S. torvum were used with suitable Boolean operators. Sixteen research articles were finally included in this systematic review after considering some inclusions and exclusions criteria. The evidence that supported S. torvum use for hypertension included its capability in reducing blood pressure in normal and high fructose-induced hypertensive rats, and also its diuretic effect by increasing sodium excretion and total urinary output in normal and in nitric-oxide deprived rats, as well as the ability to inhibit ACE, the key enzyme that mediates consequential increment of blood pressure. On contrary, S. torvum also induced partial vasoconstriction and amplified the hypertensive effect in the nitric-oxide-deprived hypertensive rats. In conclusion, this review found scientific evidence asserting the traditional use of S. torvum for hypertension with some conflicting findings in some study models. Therefore, this ethnomedicinal claim warrants more scientific verification, especially on its effect on the essential hypertension model which is very common in humans but has not yet been explored.

Rationale: Orthodontic camouflage serves its purpose in treating mild to moderate skeletal dysplasia and in conditions where the patient is reluctant to opt for orthognathic surgery or when it is contraindicated. Patient Concerns: A 22-year-old male was concerned about his irregular teeth. Diagnosis: Angle's dentoalveolar class III malocclusion on class III skeletal on an average mandibular plane angle with anterior crossbite, deep bite, crowding in maxillary and mandibular anteriors, proclined maxillary anteriors and retroclined mandibular anteriors with reverse overjet and congenitally missing 12, 22, palatally impacted 13 and retained deciduous 63 and palatally placed 23. Treatment: Orthodontic camouflage with a multi-disciplinary approach. Outcome: Optimal functional and dentofacial aesthetics were achieved by 22 months. Take-Away Lesson: The limitations of camouflage must be kept in mind and explained to the patient. The biomechanics need to be customized and integrating different specialties helps maximize the treatment benefits.

The purpose of this review was to assess the literature regarding the decontamination of resin cement before the luting procedure in order to provide clinicians with a comparative overview of decontamination effects. A total of 19 articles were selected for inclusion in this review. The results indicated that bonding effectiveness is reduced due to residual adhesion inhibitors such as saliva, blood, hemostatic agents, and temporary/provisional cement. Self-etching and self-adhesive systems tend to be more negatively affected by adhesion inhibitors than do etch and rinse systems. Cleaning with an ultrasonic scaler or rotating brush have demonstrated conflicting effects in several studies. Some studies have reported that phosphoric acid has negative effects and recommend mild acid for decontamination. The application of phosphoric acid followed by sodium hypochlorite has been shown to help avoid negative effects. Alumina blasting has been investigated as a mechanical cleaning method in a relatively large number of experiments, most of which have confirmed its effectiveness. An intraoral cleaner containing functional monomers that has become commercially available in recent years is a promising method in clinical practice because it can easily and effectively remove temporary adhesive material. In addition, adhesion inhibitors can be easily removed from resin-coated dentin surfaces.
Maximizing the antitumor efficacy of doxorubicin (DOX) with a new drug delivery strategy is always desired in the field of biomedical science. Because the clinical applications of DOX in the treatment of cancer is limited by the side effects related to the dose. Herein, we report the co-loading of DOX and resveratrol (RESV) using an injectable in situ formed sodium deoxycholate hydrogel (Na-DOC-hyd) at the pH of the tumor extracellular microenvironment. The sequential, controlled, and sustained release of RESV and DOX for synergistic antitumor effects was confirmed by entrapping G4.5-DOX in the RESV-loaded Na-DOC hydrogel (Na-DOC-hyd-RESV). The synergistic antitumor activity of Na-DOC-hyd-RESV+G4.5-DOX was assessed on HeLa cell xenograft tumor in BALB/c nude mice. In the MTT biocompatibility assay, both the G4.5 PAMAM dendrimer and Na-DOC-hyd exhibited negligible cytotoxicity up to the highest dose of 2.0 mg mL<sup>−1</sup> in HeLa, MDA-MB-231, and HaCaT cells. The release profiles of DOX and RESV from the Na-DOC-hyd-RESV+G4.5-DOX confirmed the relatively rapid release of RESV (70.43 ± 1.39%), followed by that of DOX (54.58 ± 0.62%) at pH 6.5 in the 7 days of drug release studies. A single intratumoral injection of Na-DOC-hyd-RESV+G4.5-DOX maximally suppressed tumor growth during the 28 days of the treatment period. Na-DOC-hyd-RESV+G4.5-DOX did not cause any histological damage in the major visceral organs. Therefore, this Na-DOC-hydrogel for dual drugs (DOX and RESV) delivery at the pH of the tumor extracellular microenvironment is a promising, safe, and effective combination for antitumor chemotherapy.
OBJECTIVES: To determine the demographic, clinical and radiographic features of the central giant cell granulomas (CGCG) of jaws.
METHODS: This observational study was conducted at Outpatient Department of Oral and Dental Hospital, Khyber College of Dentistry Peshawar and private clinics at Peshawar, Nowshera, Mardan and Kohat, from June 2006 to May 2018. Sixty-eight cases of CGCG of jaws, excluding known patients of syndromes and hyperparathyroidism, confirmed by biopsy were included in this study by convenience sampling.
RESULTS: Age ranged from 4-50 years with mean of 22.35±11.68 years. Most of the patients were from 21-30 years (n=28/68; 41%). CGCG were slightly more frequent in females (n=36/68; 53%) as compared to males (n=32/68; 47%). Anterior part of mandible was the most common site involved (n=32/68; 47.1%). There was cortical expansion in 53 out of 68 cases. Tooth mobility was found in more than half of cases (n=36.68; 52.9%). Only four cases of lip numbness, while no case of spontaneous bleeding (three cases of bleeding on touch were seen). Among all the radiolucencies, majority of CGCG (n= 40/68; 58.8%) had well define borders while 41.2% of CGCG had diffuse borders. Majority of CGCG were unilocular. Tooth resorption was seen in about one-third patients (n=24/68; 35.3%).
CONCLUSION: The clinical and radiographic features of some CGCG show benign features like non-mobile teeth, only buccal cortical expansion, uniloculor radiolucency, no tooth resorption and well define borders. However, some show aggressive features like tooth mobility, bicortical expansion, multiloculor radiolucency, root resorption and ill-defined borders.

Objective: To evaluate the depression on different stages (mild, moderate and severe) among undergraduate students of
pre-clinical & clinical settings on the basis of gender.
Study Design and Setting: The cross sectional study was carried out among undergraduate medical students of Bahria
University medical and dental College (BUMDC) Karachi from September 2017 – December 2017.
Methodology: The participants were 125 medical students of first year MBBS and 125 students of final year MBBS which
were labeled as pre-clinical and clinical groups respectively. The survey instrument used was PHQ-9 scale. This scale
divides depression into mild, moderate and severe categories with the help of scores. Percentage of students in different
levels of depression was calculated in both the groups.
Results: Mild depression was experienced more (39%) in pre-clinical medical students and (32%) in clinical students.
On the other hand clinical medical students showed an upward trend for “severe depression” (19%) as compare to preclinical
students (6%) as showed in Table 1. Gender based comparison was done between male and female students in pre-clinical
and clinical groups separately. Strikingly, the results showed that females were more depressed than males in both cohorts.
Conclusion: It was concluded that severe depression was equal in males and females in the preclinical group as compared
to clinical group. Gender based comparison showed that severe depression was higher in females than males of clinical
years whereas mild and moderate depression was also more frequents in females of clinical years.
Purpose: To investigate the clinical and histopathological characteristics of patients with uterine and ovarian sarcomas and analyse surgical operations already performed.
Material and Methods: The retrospective study included 17 patients with uterine and 2 patients with ovarian sarcomas, who were diagnosed and operated on for three years at St. Marina University Hospital in Pleven, Bulgaria.
Results: In the group of uterine sarcomas, the highest incidence was that of leiomyosarcomas (53.3%), followed by endometrial stromal sarcomas (33.3%) and the homologous carcinosarcomas (13.3%). Most of the patients were diagnosed in the first clinical stage (73.3%), and the most common surgery performed was total abdominal hysterectomy with salpingo-oophorectomy, with or without omentectomy (53.3%). The two patients with ovarian tumours were histologically diagnosed with carcinosarcoma.
Conclusions: Genital sarcomas are a heterogeneous group of rare malignant diseases with poor prognoses. Early detection, adequate histological diagnosis and staging are of utmost importance for control.
Statement of problem: Secondary dental caries is a common clinical finding in composite restoration. The development of a bactericidal dental adhesive provides a promising method to reduce the risk of secondary caries.
Objectives: This study aimed to assess the antibacterial activity of silver (Ag) and titanium dioxide (TiO2) nanoparticles incorporated into an experimental dentin bonding agent formulation.
Materials and Methods: Ag and TiO2 nanoparticles at 0.05, 0.1, 0.2, 0.5, and 1 wt% concentrations were incorporated into the adhesives. The suspensions were sonicated to ensure homogenous dispersion of nanoparticles in the adhesive system. Formulation was composed of acetone, 2,2-bis[4-(2-hydroxy-3-methacryloxypropoxy)phenyl]propane (Bis-GMA), 1,6-bis-[2-methacryloyloxyethyl carbonyl amino]-2,4,4-trimethylhexane (UDMA), trimethylolpropane trimethacrylate (TMPTMA), 2-hydroxyethyl methacrylate (HEMA), and photoinitiator, with polyvinylpyrrolidone (PVP) as the stabilizer. We counted the colony-forming units (CFU%) of two cariogenic bacteria, Streptococcus mutans (S. mutans) and Lactobacillus acidophilus (L. acidophilus), that were exposed to the powdered light cured adhesive specimens. The effects of various concentrations of each nanoparticle were compared by one-way ANOVA, followed by the post hoc Bonferroni test.
Results: All samples exhibited definite antibacterial activity (P<0.05) compared to the control specimens. The Ag nanoparticle samples showed higher antibacterial properties compared to the TiO2 nanoparticle samples. Increasing the concentration of nanoparticles resulted in significant differences in bactericidal properties, with the exception of 0.2 to 0.5 wt% Ag nanoparticle specimens exposed to S. mutans and the 0.2 to 0.5 wt% TiO2 nanoparticle specimens exposed to L. acidophilus.
Conclusions: These metal-based nanoparticles exhibited dose-dependent bactericidal activities. The Ag nanoparticles had higher antibacterial activity compared to the TiO2 nanoparticles. Incorporation of these nanoparticles into dental adhesives is a promising way to reduce the risk of secondary caries. However, further clinical evaluations should be performed.

The survival of patients even with disseminated disease reached 7–8 years after introduction of imatinib and sunitinib for the treatment of gastrointestinal stromal tumours (GIST) into everyday clinical practice. These drugs efficacy is largely determined by the presence and any mutations of C-KIT and PDGFR genes. It was established that new mutations appear in most tumours against the background of tyrosine kinase inhibitors therapy, which causes the development of secondary resistance and the progression of the disease in most cases. The search for opportunities to overcome the newly developed or initially existing resistance caused by different gene mutations continues to be of vital importance. One of such drugs is regorafenib, which has demonstrated antitumour activity against progression on imatinib and/or sunitinib. The paper reviews the studies of the efficacy of regoraphanib in patients with disseminated GIST, taking into account the presence and any mutations of C-KIT and PDGFR genes, and presents a description of their own clinical case of prolonged use of the drug in a patient who have received earlier both imatinib and sunitinib.
The state of local immunity of the oral cavity in children with disabilities aged 12 to 18 years who had inflammation of the periodontal disease of varying severity. Determined the activity concentrations of lysozyme and secretory Ig A in oral fluid. Lysozyme activity in the oral fluid is opposite depending on the severity of inflammation in periodontal tissues, the concentration of secretory Ig A is inversely proportional to the severity of generalized periodontitis in this category of patients.
The problem of generalized periodontitis, which occurs in children with disabilities are among the most pressing in modern dentistry. Itself this disease contributes to premature removal of teeth in children. Poor oral hygiene, presence of parodontopathogenic microflora is the trigger for the development of chronic generalized inflammation in periodontal tissues in children with disabilities. Toxins of microorganisms initiate a cascade of biochemical processes that destroy periodontal tissues, cause inflammation and monogamy generalized process, a sharp deterioration in the severity of inflammatory diseases.
Therefore, for effective treatment and prevention of periodontal diseases it is important to determine the state of local immunity of the oral cavity in children with disabilities.
The purpose of the study is to investigate the state of local immunity in children with disabilities aged 12 to 18 years suffering from generalized periodontitis of varying severity.
The object of study: estimulan oral fluid (mixed saliva), which was collected in the morning on an empty stomach by splavovanie in a sterile tube. Further oral fluid in tubes, centrifuged, and used the supernatant. The samples were stored at a temperature of 18With, used for biochemical analysis after thawing.
The criteria for the assessment of local immunity of the oral cavity of children with disabilities were factors of the immune system – lysozyme, secretory SIg A and their ratio.
The results obtained were processed statistically with Studentam Fischer.
As a result of clinical examination of 54 children with disabilities aged 12 to 18 years, which was planned sanitation of the oral cavity in KU "Zaporozhye regional children's clinical hospital under General anesthesia were identified diseases of periodontal tissues in 42 children (generalized periodontitis I degree of severity – 16 children, II severity – 14 children, III severity – 12 children and 12 children with healthy periodontium.
Children were divided into groups. Children with disabilities aged 12 to 18 years with a history of generalized periodontitis I degree of severity were in the control group №1, children with the disease generalized periodontitis II degree of severity and control group No. 2, children with III degree of severity of generalized periodontitis and control group No. 3. 12 children with disabilities aged 12 to 18 years, had a healthy periodontium formed the comparison group.
The study results of oral fluid indicate a fairly high level of lysozyme in children of the comparison group, with intact periodontium. Variations of lysozyme in 6 months in this group and 12 months after sanation of oral cavity minor.
The results of studies of secretory Ig A show that in children of the control group, the concentration of A SIg is inversely proportional to the severity generalsaving periodontitis.
After rehabilitation of the oral cavity children underwent professional hygienic cleaning of the mouth 1 time per month, assigned therapeutic and prophylactic anti-inflammatory toothpaste and standard Protocol scheme local anti-inflammatory treatment. The treatment resulted in clinical improvement, but the quantity of lysozyme and secretory Ig A in oral fluid was improved only after 6 months in the three control groups and decreased again at 12 months.
Conclusions: lysozyme Activity in saliva of children with disabilities aged 12 to 18 years with generalized periodontitis disease of various degrees of gravity is in the opposite direction depending on the severity of inflammation in periodontal tissues.
Assessment of the level of lysozyme and secretory Ig A in oral fluid is a diagnostic indicator of generalized periodontitis and the quality of his treatment.
Thus, we conducted the assessment of the state of local immunity of the oral fluid of children with special needs aged 12 to 18 years suffering from generalized periodontitis demonstrates the need for serious immunological support in the treatment of periodontal disease in this group of patients.
Aims: To help dentists to communicate with the hearing impaired patients, reach an accurate diagnosis and explain the treatment plan by learning some signs and gestures used in the nonverbal communication (NVC) and by devising some new signs and gestures related to dentistry which shall be easy to learn and understand both by the hearing impaired patients and the dentists. Settings and Design: The study was carried out on 100 hearing impaired students in the age group of 10–14 years in two special schools for hearing impaired children located in two different states of India, where different spoken languages and different sign languages are used. One dentist (expert dentist) was trained in the NVC and the other dentist (non expert dentist) had no knowledge of this type of communication, communicated the same sets of statements related to dentistry, to the hearing impaired children. One1 translator was assigned to judge their interactions. Students were asked to tell the interpreter at the end of each signed interaction what they understood from the statement conveyed to them by both the dentists. Statistical Analysis Used: All data collected were subjected to statistical analysis using Chi-square test and odds ratio test. Results: In the special school of 1st state, the nonexpert dentist conveyed only 36.3% of the information correctly to the students, whereas the expert dentist conveyed 83% of the information correctly. In the special school of 2nd state, the nonexpert dentist conveyed only 37.5% of the information correctly to the students, whereas the expert dentist conveyed 80.3% of the information correctly. Conclusions: Dentists should be made aware of the NVC and signs and gestures related to dentistry should be taught to the hearing impaired students as well as the dental students.
