Project description:Molecular alterations induced by tobacco usage are not well characterized in oral squamous cell carcinoma. Tobacco consumption in chewing or smoking forms is a known risk factor in oral cancer. To understand proteomic changes due to tobacco usage in oral cancer patients we carried out comparative proteomic analysis in oral cancer patients who had history of tobacco using habits (patients who chewed tobacco and patients who smoked tobacco) and those with no history of tobacco consumption. Proteomic analysis resulted in the quantification of 5,848 proteins in smoker cohort, 5,216 in chewer, and 5,320 in non-user cohort. Among these 443, 72 and 139 were significantly dysregulated proteins (p-value≤ 0.05 and 2-fold change) in smoker, chewer and non-user cohorts, respectively. Gene ontology and pathway analysis of significantly dysregulated proteins revealed enrichment of distinct biological processes and pathways in each patient cohort. Proteins associated with collagen formation and antigen processing/presentation pathway were dysregulated in oral cancer patients who smoked tobacco, while keratinization process was enriched in patients who chewed tobacco. We also observed dysregulated proteins in non-users to be involved in ECM proteoglycans, metabolism of carbohydrates and glycosaminoglycans. Immune signaling pathways and muscle contraction were identified as common events dysregulated in all three cohorts. This study helps us to decipher the proteomic alterations induced by tobacco usage in oral cancer patients and will assist in identification of early detection markers to identify high risk population

Project description:Dysbiosis of the oral microbiome has been found to play a key role in the genesis and progression of oral cancer (OC). Tobacco chewing, a risk factor for oral cancer, is also associated with oral dysbiosis. Since tobacco chewing is a lifestyle habit in the South Asian subcontinent, including India, and contributes to one-third of the global oral cancer burden; we aimed to identify the oral bacterial diversity of Indian oral cancer patients and tobacco chewers. We used 16S rRNA amplicon sequencing to study the composition of oral microbiota in OC patients and tobacco chewers in India and compared it with healthy controls. The abundance of predominant phyla, Firmicutes, and Bacteroidetes varied between the study groups. Our study identified Leptotrichia, Treponema, Lautropia, and Cardiobacterium as significantly enriched in tobacco chewers, whereas genera Pseudomonas, Capnocytophaga, and Mycoplasma were enriched in oral cancer, which could be potential biomarkers for the Indian population. Furthermore, the functional prediction revealed that genes involved in lipid biosynthesis and fatty acid elongation were upregulated in the oral cancer group, whereas those for the reductive TCA cycle were upregulated in the tobacco group. As the role of bacteria in oral cancer is becoming more evident, identification of bacterial diversity and biomarkers for tobacco chewers and OC patients can aid in the early diagnosis of OC in high-risk individuals.

Project description:Information on predictors of quitting behavior among construction site tobacco users is scarce in India. Hence, this study was conducted to assess the intention of tobacco users toward quitting and its predictors with reference to sociodemographic profile.A community-based, observational study was conducted on adult 172 construction site workers in a university campus of Delhi. Data were collected by an interview using the WHO-adopted, pretested, semi-structured questionnaire. Chi-square test was used for univariate analysis. Pearson's correlation coefficient and multivariate logistic regression model were used to identify the predictors.Of the 172 users, 73% had intention to quit. More than half of smokers (56.5%) and 81% of smokeless tobacco users intended to quit. Majority of the tobacco users who intended to quit were literate (75.0%), started tobacco use >15 years of age (75.4%), occasional tobacco users (78.9%), and less dependent on nicotine (74.4%).Suitable plan for quitting keeping in mind this vulnerable group of workers should be developed depending on the literacy, type of tobacco used, and nicotine dependency.

Project description:Oral squamous cell carcinoma (OSCC) is a common cancer of the oral cavity in India. Cigarette smoking and chewing tobacco are known risk factors associated with OSCC. However, genomic alterations in OSCC with varied tobacco consumption history are not well-characterized. In this study, we carried out whole-exome sequencing to characterize the mutational landscape of OSCC tumors from subjects with different tobacco consumption habits. We identified several frequently mutated genes, including TP53, NOTCH1, CASP8, RYR2, LRP2, CDKN2A, and ATM. TP53 and HRAS exhibited mutually exclusive mutation patterns. We identified recurrent amplifications in the 1q31, 7q35, 14q11, 22q11, and 22q13 regions and observed amplification of EGFR in 25% of samples with tobacco consumption history. We observed genomic alterations in several genes associated with PTK6 signaling. We observed alterations in clinically actionable targets including ERBB4, HRAS, EGFR, NOTCH1, NOTCH4, and NOTCH3. We observed enrichment of signature 29 in 40% of OSCC samples from tobacco chewers. Signature 15 associated with defective DNA mismatch repair was enriched in 80% of OSCC samples. NOTCH1 was mutated in 36% of samples and harbored truncating as well as missense variants. We observed copy number alterations in 67% of OSCC samples. Several genes associated with non-receptor tyrosine kinase signaling were affected in OSCC. These molecules can serve as potential candidates for therapeutic targeting in OSCC.

Project description:OBJECTIVE:Evaluate socio-demographic, family and behavioral factors associated with oral health literacy (OHL) in adolescents. METHODS:Cross-sectional study conducted with adolescents aged 15 to 19 years in Campina Grande, Brazil. Parents/guardians answered a questionnaire addressing socio-demographic data. The adolescents answered validated instruments on family cohesion and adaptability (family adaptability and cohesion evaluation scale), drug use (alcohol, smoking and substance involvement screening test), type of dental service used for last appointment and OHL (Brazilian version of the Rapid Estimate of Oral Health Literacy in Dentistry). Two dentists were trained to evaluate OHL (K = 0.87-0.88). Descriptive analysis was performed, followed by Poisson regression analysis (? = 5%). A directed acyclic graph was used to select independent variables in the study. RESULTS:The following variables remained associated with better OHL: high mother's schooling level (RR = 1.07; 95%CI: 1.03-1.12), high income (RR = 1.04; 95%CI: 1.01-1.09), white ethnicity/skin color (RR = 1.05; 95%CI: 1.01-1.10), married parents (RR = 1.04; 95%CI: 1.01-1.09), "enmeshed" family cohesion (RR = 1.21; 95%CI: 1.12-1.30), "structured" (RR = 1.06; 95%CI: 1.01-1.12) or "rigid" (RR = 1.11; 95%CI: 1.04-1.19) family adaptability, having more than five residents in the home (RR = 1.07; 95%CI: 1.01-1.14) and having used a private dental service during the last appointment (RR = 1.08; 95%CI: 1.03-1.13). CONCLUSION:Family functioning and socio-demographic factors influence the level of oral health literacy among adolescents.

Project description:BackgroundThe changes in hormones, diet, and hygiene associated with pregnancy are associated with oral diseases. There is insufficient awareness of the importance of oral health during pregnancy. This study investigated the oral health status and knowledge amongst pregnant women in Shanghai.MethodsThis cross-sectional study enrolled pregnant women at the Shanghai Red House Obstetrics & Gynecology Hospital in December 2020. The Fourth National Oral Health Questionnaire was used to evaluate the oral health status. Decayed/missing/filled teeth (DMFT) were the sum of the number of decayed, missing due to caries, and filled teeth. The chi-square test and Kruskal-Wallis test were used to compare the groups.ResultsA total of 224 pregnant women were enrolled. The rates of dental caries were 69.8%, periodontal health was 1.8%, calculus detection was 95.6%, shallow periodontal pocket was 51.1%, deep periodontal pocket was 4.9%, regular oral examination was 22.8%, correct brushing was 49.6%, and prepregnancy oral examination was 20.1%. DMFT was 2.27, and the caries filling ratio was 45.4%. The number of missing teeth increased with age (P < .001). Only 26.3% used dental floss more than once a day, 47.3% rinsed the mouth more than twice a day, and 46.9% cleaned their tongue coating every week. In addition, 99% of the pregnant women agreed that "oral health was vital to their lives" and 97.7% agreed that "regular oral examination was necessary."ConclusionsThe oral health status amongst pregnant women in Shanghai was poor, but oral health awareness and attitudes were relatively high.

Project description:Data on the microbial composition among tobacco chewers and oral cancer patients in Rajasthan, India is of interest. NGS analysis from tobacco chewers and oral cancer comprised the most abundant and core microbial taxa in the oral cavity. It shows that highly pathogenic phylum consisting of 6% Fusobacteria and 9% Firmicutes are observed in oral cancer samples; whereas, 0.6% Treponema, 34% Firmicutes, 0.02% Mollicutes, and 4% Fusobacteria are seen in tobacco chewers. Thus, data shows that the most abundant and core microbial taxa are found in the oral cavity of tobacco chewers and oral cancer patients in Rajasthan, India.

Project description:To examine the association between oral health literacy (OHL) with sociodemographic variables and dental visitation in adults presenting to an urban emergency department (ED). Methods: This was a cross-sectional study of a convenience sample of 556 adults aged 18?90. Interview data from the study were used to collect self-reported sociodemographic characteristics and dental visitation history. The OHL of the study participants was measured using the Health Literacy in Dentistry scale (HeLD-14), and the score was dichotomized into low and high OHL. Bivariate associations between sociodemographic variables and OHL were conducted using chi-square tests, and logistic regression was used to examine the association between OHL and dental visitation within the past year. Results: Sixty percent of participants reported having visited a dentist within the past year. Over two-thirds of the sample was classified as having low OHL. Low OHL was more common in non-White races, less-educated, single, unemployed, and lower-income individuals, and those without a primary care physician or dental insurance (p < 0.05). Patients with low oral health literacy were 39% less likely to have visited the dentist in the past year (OR = 0.61; 95% CI 0.38, 0.96). Conclusions: This study highlights significant disparities in OHL. Interventions targeted toward the unique needs of underserved populations should be developed to improve health outcomes.

Project description:The purpose of this study was to investigate the status of occupational burnout and its influence on the psychological health of factory workers and miners, in order to provide theoretical basis and reference for alleviating occupational burnout and promoting psychological health. The cross-sectional study investigated 6130 factory workers and miners with online questionnaire; the Chinese Maslach Burnout Inventory (CMBI) and Symptom Check List-90 (SCL-90) were used. In total, 6120 valid questionnaires were collected; effectiveness was 99.8%. The percentage of the factory workers and miners suffering from occupational burnout was 85.98% and psychological health problems was 38.27%. A statistically significant difference was observed in relation to the prevalence of occupational burnout among factory workers and miners of different sex, education level, labor contracts, work schedule, monthly incomes, weight, hypertension, age, working years, working hours per day, working hours per week, coal dust, silica dust, asbestos dust, benzene, lead, and noise. The detection rate of psychological health was higher for males than females. The detection rate of psychological health was higher for working days per week less than 5 days than more than 5 days. The detection rate of psychological health with high school education, senior professional title, night shift, divorced, monthly income less than 3000 yuan, weight more than 75?kg, age more than 45 years, and working years between 25 and 30 years was higher than that of the other groups. The results showed that sex, education level, professional title, work schedule, monthly income, hypertension, age, working years, asbestos dust, benzene, and occupational burnout affected psychological health among factory workers and miners. Factory workers and miners had high levels of occupational burnout, and occupational burnout was a risk factor that can lead to psychological health.

Project description:BackgroundMinor Recurrent Aphthous Stomatitis (RAS) represents a disease which is very difficult to prevent. This case-control study focused on possible associations between minor Recurrent Aphthous Stomatitis in children, their oral health, and underlying behavioral indexes of children's attitudes and habits pertaining to (home) oral hygiene, with the further goal of enabling the dentist to prevent these specific kind of lesions, both from a clinical and a broader psychosocial perspective.MethodsFour hundred one school-children (5-10 years old) in Milan (Italy) were submitted to an intra-oral examination, and interviewed with the aid of a brief psychosocial questionnaire.ResultsAt the clinical level, statistically significant associations were observed between the presence of decayed teeth and minor Recurrent Aphthous Stomatitis (Odds Ratio: 3.15; 95% CI: lower limit 1.06; upper limit: 9.36; Z-test: 2.07, p = 0.039; Chi-square = 4.71, p = 0.030), and between the Decayed Missing or Filled Teeth (DMFT) index and minor aphthous stomatitis (Odds Ratio: 3.30; 95% CI: lower limit 1.13; upper limit: 9.67; Z-test = 2.18, p = 0.029; Chi-square = 5.27; p = 0.022), both results pointing to a significant increase-by circa 3 times-in the risk of developing minor Recurrent Aphthous Stomatitis in children exposed to the two above-identified factors (i.e., the presence of decayed teeth and a clearly compromised oral condition, as signaled by the DMFT index), if compared with the risk run by their non-exposed counterparts. At the psychosocial level of analysis, statistically significant associations were observed (1) between children's practice of spontaneously brushing teeth when not at home and a comparatively lower (i.e. better) Decayed Missing or Filled Teeth index (Chi-square: 8.95; p = 0.011), and (2) between receiving parental aid (e.g., proper brushing instructions) while practicing home oral hygiene and a significantly reduced presence of decayed teeth (Chi-square = 5.40; p = .067; Spearman's Rho, p = .038). Further, significant associations were also observed between children's reported severity of dental pain and both (a) the presence of decayed teeth (Chi-square = 10.80; p = 0.011), and (b) children's (poor) oral health condition as expressed by the Decayed Missing or Filled Teeth index (Chi-square = 6.29; p = 0.043). Interestingly, specific lifestyles and social status, showed no systematic association to other clinical or psychological/psychosocial indices.ConclusionsThese systematic relations suggest that, in the presence of Recurrent Aphthous Stomatitis in pediatric patients, the dentist should carefully monitor children for potential carious lesions, implement protocols of prevention to control Recurrent Aphthous Stomatitis disease in children affected by caries, and also be particularly aware of the right or wrong habits children may acquire in the course of continued social exchange with their caregivers and peers.
