Evaluation of dietary patterns and their impact on eye health among Saudi adults-A multi-regional cross-sectional analysis in Makkah, Riyadh, and Qassim.

Background and aim: Nutrition plays a vital role in maintaining and improving vision health. However, little is known about dietary intake habits and their correlation with vision health among adults in the Kingdom of Saudi Arabia (KSA). The present survey was aimed to assess dietary patterns and vision health among Saudi adults and to determine the association between dietary patterns and vision health. Methods: The present analytical study was carried out among 1,234 Saudi adults in the Makkah, Riyadh, and Qassim regions of KSA. We used the Arabic version of the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) and the diet quality screener (DQS). We applied Mann-Whitney U and Kruskal-Wallis tests to determine the association between vision function score and demographic characteristics. Furthermore, the Spearman correlation test was used to determine the relationship between the DQS and the NEI VFQ-25. Results: Of the studied population, the highest score obtained through the NEI VFQ-25 was in the social function domain (mean ± SD = 76.64 ± 18.63), followed by the general vision domain (mean ± SD = 75.21 ± 15.16) and was negatively correlated with age. Regarding dietary patterns, the intake of lean protein sources per week was the highest, with a mean intake of 4.17 days per week, followed by that of whole grains and milk or dairy products, with a mean intake of around four days per week. There was a significant correlation between various dietary intakes and visual function scores. Conclusion: The present survey underscores the significance of understanding regional dietary patterns and their implications for vision health. Furthermore, our study's findings indicate a need for targeted nutritional intervention measures to improve the vision health of this population.

Personalizing Nutrition Strategies: Bridging Research and Public Health.

In recent years, although life expectancy has increased significantly, non-communicable diseases (NCDs) continue to pose a significant threat to the health of the global population. Therefore, eating habits have been recognized as key modifiable factors that influence people's health and well-being. For this reason, it is interesting to study dietary patterns, since the human diet is a complex mixture of macronutrients, micronutrients, and bioactive compounds, and can modulate multiple physiological processes, including immune function, the metabolism, and inflammation. To ensure that the data we acquired were current and relevant, we searched primary and secondary sources, including scientific journals, bibliographic indexes, and databases in the last 15 years with the most relevant articles. After this search, we observed that all the recent research on NCDs suggests that diet is a critical factor in shaping an individual's health outcomes. Thus, cardiovascular, metabolic, mental, dental, and visual health depends largely on the intake, habits and patterns, and nutritional behaviors. A diet high in processed and refined foods, added sugars, and saturated fats can increase the risk of developing chronic diseases. On the other hand, a diet rich in whole, nutrient-dense foods, such as vegetables, fruits, nuts, legumes, and a high adherence to Mediterranean diet can improve health's people.

Keep your eyes healthy: eat organic food.

This letter is a comment on the 2023 article entitled "Effect of xanthophyll-rich food and supplement intake on visual outcomes in healthy adults and those with eye disease: a systematic review, meta-analysis, and meta-regression of randomized controlled trials," recently published in Nutrition Reviews, by Hu et al.

Xanthophyll pigments dietary supplements administration and retinal health in the context of increasing life expectancy trend.

Introduction: Medicine faces nowadays the trend of increasing life expectancy of human population, with the resulting increase of degenerative age related diseases prevalence, combined with the risks of less tempered sun radiations environment exposure. Under these circumstances, our work pointed out on evaluating the effect of some xanthophyll pigments dietary supplements, actually widely recommended, for prevention of retinal degenerative damages and for slowing down the progression of such age related changes if they have already occurred. These dietary supplements are already well known for their total antioxidant activity, proven by photochemiluminescence method using Total Antioxidant Capacity in Lipid soluble-substances procedure. Materials and methods: The study recruited a number of 120 subjects equally divided on genders. The lot included a first group of 60 patients with comparable ages (all of them over 50 years and divided in 2 segments of age: 50-60 and over 60) and suffering from comparable retinal age-related degenerative abnormalities (mild/medium severity age-related macular degeneration according to Wisconsin Age-Related Maculopathy Grading System), and a second group, considered control, including a similar number of healthy, normal retina subjects belonging to same age and gender categories. There were evaluated at baseline the eye medical status and the retinal risk by specific methods: complete eye check-up, Amsler grid, specific standardized questionnaires focused on visual function and its impact on the quality of current life. Both groups, patients and control, received similar dosages of xanthophyll pigments dietary supplements including lutein and zeaxanthin during 18 months after baseline; at the end of this supplementation period a new evaluation was conducted. In the second part of the research all subjects involved received a new dietary supplement in which the same xanthophylls were enriched with C and E vitamins and oligo-elements Zinc and Copper. At the end of three years duration supplementation, the subjects were reevaluated and the paper presents the conclusions on the matter, pointing on the impact of xanthophyll supplements on visual health. Results: Correlation tests were applied to the complete set of data. Correlation tests have values between -1 and +1. The value -1 represents the negative correlation (reverse proportionality) meanwhile the value +1 represents the positive correlation (direct proportionality). The charts show the curves that are fitting experimental data. The dependence is linear in nature, and the value R2, as it approaches more the value 1, represents a better match with the experimental data (the data are in a percentage of approximately 99% on these straight lines of type y = ax + b). In the charts, there were noted the average values of the scores for healthy control patients with "Control", and the average values of the scores for the patients with existing age related degenerative retinal pathology at baseline with "Patients". Discussion: The retinal function and the impact of visual condition on health were both evaluated at baseline, 18 months and 36 months after baseline, by visual acuity, ophthalmoscopy fundus examination, Amsler test and by asking the subjects to answer the visual function questionnaires: EQ-5D, NEI-VFQ-25, as measures of health status quality and of the influence on welfare. The study revealed that under supplementation both control healthy subjects and patients with known degenerative retinal pathology included in the 50-60 years of age group evolved almost the same way, leading to the conclusion that administered xanthophyll pigments-based supplements, simple or enriched, managed to slow down the progression of abnormal degenerative vision loss to a rate comparable to physiological aging-related vision loss. It was also observed that intake of xanthophyll pigments dietary supplements preserved the general health condition and maintained relatively constant vision on the entire 36th months follow-up research duration in patients presented with existing age related degenerative retinal pathology at baseline. For healthy subjects, evaluation showed an improvement in results after dietary supplementation, with maintenance of constant vision and a significantly increase of general condition, in a positive sense. For subjects over the age of 60 dietary supplements intake was even more effective compared to younger group in providing better control of degenerative processes.

Understanding the Roles of Very-Long-Chain Polyunsaturated Fatty Acids (VLC-PUFAs) in Eye Health.

Lipids serve many roles in the neural system, from synaptic stabilization and signaling to DNA regulation and neuroprotection. They also regulate inflammatory responses, maintain cellular membrane structure, and regulate the homeostatic balance of ions and signaling molecules. An imbalance of lipid subgroups is implicated in the progression of many retinal diseases, such as age-related macular degeneration (AMD), retinitis pigmentosa, and diabetic retinopathy, and diet can play a key role in influencing these diseases' onset, progression, and severity. A special class of lipids termed very-long-chain polyunsaturated fatty acids (VLC-PUFAs) is found exclusively in mammalian vertebrate retinas and a few other tissues. They comprise <2% of fatty acids in the retina and are depleted in the retinas of patients with diseases like diabetic retinopathy and AMD. However, the implications of the reduction in VLC-PUFA levels are poorly understood. Dietary supplementation studies and ELOVL4 transgene studies have had positive outcomes. However, much remains to be understood about their role in retinal health and the potential for targeted therapies against retinal disease.

Comparing Telephone Survey Responses to Best-Corrected Visual Acuity to Estimate the Accuracy of Identifying Vision Loss: Validation Study.

BACKGROUND: Self-reported questions on blindness and vision problems are collected in many national surveys. Recently released surveillance estimates on the prevalence of vision loss used self-reported data to predict variation in the prevalence of objectively measured acuity loss among population groups for whom examination data are not available. However, the validity of self-reported measures to predict prevalence and disparities in visual acuity has not been established. OBJECTIVE: This study aimed to estimate the diagnostic accuracy of self-reported vision loss measures compared to best-corrected visual acuity (BCVA), inform the design and selection of questions for future data collection, and identify the concordance between self-reported vision and measured acuity at the population level to support ongoing surveillance efforts. METHODS: We calculated accuracy and correlation between self-reported visual function versus BCVA at the individual and population level among patients from the University of Washington ophthalmology or optometry clinics with a prior eye examination, randomly oversampled for visual acuity loss or diagnosed eye diseases. Self-reported visual function was collected via telephone survey. BCVA was determined based on retrospective chart review. Diagnostic accuracy of questions at the person level was measured based on the area under the receiver operator curve (AUC), whereas population-level accuracy was determined based on correlation. RESULTS: The survey question, "Are you blind or do you have serious difficulty seeing, even when wearing glasses?" had the highest accuracy for identifying patients with blindness (BCVA ≤20/200; AUC=0.797). The highest accuracy for detecting any vision loss (BCVA <20/40) was achieved by responses of "fair," "poor," or "very poor" to the question, "At the present time, would you say your eyesight, with glasses or contact lenses if you wear them, is excellent, good, fair, poor, or very poor" (AUC=0.716). At the population level, the relative relationship between prevalence based on survey questions and BCVA remained stable for most demographic groups, with the only exceptions being groups with small sample sizes, and these differences were generally not significant. CONCLUSIONS: Although survey questions are not considered to be sufficiently accurate to be used as a diagnostic test at the individual level, we did find relatively high levels of accuracy for some questions. At the population level, we found that the relative prevalence of the 2 most accurate survey questions were highly correlated with the prevalence of measured visual acuity loss among nearly all demographic groups. The results of this study suggest that self-reported vision questions fielded in national surveys are likely to yield an accurate and stable signal of vision loss across different population groups, although the actual measure of prevalence from these questions is not directly analogous to that of BCVA.

A Review of the Role of the School Spatial Environment in Promoting the Visual Health of Minors.

Rising childhood myopia rate has detrimental health consequences that pose a considerable challenge to health systems. The school spatial environment, which is where students are for the longest period of time, has a high health value for myopia systematic intervention. While research has demonstrated associations between physical daylight environments, medical gene and visual health, the literature currently lacks a synthesis of evidence that will act as a spatially-organized resource for school designers. This study is based on literature from the period 2000-2022 and has been taken from the Web of Science, scopus, Medline and CNKI core collection database. Collaboration, literature co-citation and quantitative and qualitative analysis, in addition to keyword co-occurrence are adopted to conduct a visual health research review. The results indicate that intensive near work activity (as a risk factor) and longer time spent outdoors (as a protective factor), are involved in visual health factors. Two main research themes are obtained and relate to: (1) The environment of visual work behavior (especially the near work learning environment) and adaptable multimedia learning environment; and (2) the environment of outdoor exposure behavior. Furthermore, with the variation of educational demands, models and concepts, there are different demands for near work behavior, and this study makes an important contribution by pointing to two future research directions, including the accurate and controllable environment of near work behavior, which operate in accordance with various educational mode requirements and the active design of the environment of outdoor exposure behavior. In referring to differences between regions and countries, as well as the development of the educational environment, it provides insight into how these demands can be controlled.

From Inner Balance to Visual Health: Unraveling the Therapeutic Role of Yoga in Optic Neuropathy and Ocular Manifestations - Narrative Review.

The optic nerve comprises approximately 1.2 million axons of retinal ganglion cells and is vulnerable to degeneration due to a myriad of causes. While traditional treatments have been the cornerstone of ocular care, emerging evidence highlights the benefits of integrative approaches, which can be used as an adjunct in the management of optic neuropathy. Yoga is a mind-body energy medicine encompasses physical postures, breath control, and meditation. Currently, it has gained attention for its holistic effects on well-being, by promoting health, preventing onset of diseases, adjunct in disease management, and for its rehabilitative potential. In addition, the underlying mechanisms through which yoga exerts its therapeutic influence, evaluates clinical outcomes, and explores potential synergistic effects with conventional treatments remain largely unexplored. Neuroprotective mechanisms of yoga, such as enhancing retinal ganglion cell function, reducing oxidative stress, coupled with its ability to modulate inflammatory processes and improve circulation, contribute to its potential benefits in visual health. Analysis of clinical studies reveals promising outcomes, including improvements in visual acuity, visual fields, quality of life, and functional outcomes in individuals with optic neuropathy and ocular manifestations who undergo yoga intervention (especially dhyaan) with awareness of breath. Furthermore, the integration of yoga with conventional treatments and complementary modalities unveils the possibilities of multidisciplinary approaches in ocular care that need evaluation. By unraveling the role of yoga intervention in ocular health, this review provides valuable insights for clinicians and researchers, fostering a deeper understanding of the mind-body connection and paving the way for enhanced visual health outcomes. Embracing yoga as an adjunctive therapy may has the potential to revolutionize the management of optic neuropathy and ocular manifestations, offering individuals a holistic approach to optimize visual well-being, reduce comorbid depression and caregiver burden, and improve overall quality of life.

The Importance of Health Literacy in Addressing Eye Health and Eye Care Disparities.

Disparities in eye health and eye care frequently result from a lack of understanding of ocular diseases and limited use of ophthalmic health services by various populations. The purpose of this article is to describe the principle of health literacy and its central role in enhancing health, and how its absence can result in poorer health outcomes. The article evaluates the current status of health literacy in visual health and disparities that exist among populations. It also explores ways to improve health literacy as a means of reducing disparities in visual health and eye care. Advancing dissemination of health information and enhancing health literacy may help not only to reduce healthcare barriers in the underserved populations but also to lessen visual health disparities.

A Latent Class Analysis of Student Eye Care Behavior: Evidence From a Sample of 6-17 Years Old in China.

Purpose: To understand the latent classes and distribution of an adolescent eye care behavior, and to provide a basis for the formulation of appropriate adolescent vision health management interventions. Methods: Information on eye behavior and eye health of primary and secondary school students in Wuhan was collected by multistage stratified cluster sampling. The latent class analysis (LCA) method was used to analyze the students' eye care behavior, and the latent class model (LCM) was built. Results: A total of 6,130 students were enrolled in this study, of which 53.56% were males, aged from 6 to 17 years old, with an average age of 10.33 ± 2.60. The latent class results classified the adolescents' eye care behaviors into bad behaviors, moderate behaviors, and healthy behaviors. The model fitting results were as follows: Akaike Information Criterion (AIC) was 36,698.216, Bayesian Information Criterion (BIC) was 36,906.565, Adjusted Bayesian Information Criterion (aBIC) was 36,808.056, and entropy was 0.838.Compared with the healthy behaviors class, the bad behaviors class was more prevalent in high schools (p = 0.003), non-demonstration schools (p = 0.001), and most of this group had astigmatism (p = 0.002). The moderate behaviors class predominately consisted of females (p = 0.001), 15-17 years old (p = 0.005, 6~8 years old as the reference), from non-demonstration schools (p < 0.001), and most had myopia (p = 0.009). Conclusion: There were differences in basic demographic characteristics, visual acuity development level, and family visual environment among different classes. In the management and intervention of an adolescent vision health, we should continue to promote the visual health management of adolescents based on visual monitoring and realize the early intervention and guidance of individuals in bad behaviors class.

Traffic Safety Improvement via Optimizing Light Environment in Highway Tunnels.

Driving in tunnel areas depends more heavily on light conditions than that on open roadways. Traditional lighting systems in highway tunnels adjust lighting parameters only caring about outside light luminance, and focus is usually on energy conservation; however, little concern is about drivers' actual physical and psychological needs. How to leverage the enormous research progress of traffic safety, light environment, human factors engineering, and modern lighting sources to create an ideal tunnel light environment that aids with ensuring driving safety and lower interference effects caused by the change of light environment will greatly improve safety level and reduce adverse influence on drivers' visual health in a tunnel area. An intelligent lighting control system designed with multiple influence factors are systematically considered. Based on sensor data from outside natural light conditions, target lighting parameters are determined per each lighting zone requires; then, lighting commands will be transferred and parsed by adaptive lighting controllers and modules, eventually LED lighting properties are altered step by step. This system helps a lot with optimizing tunnel lighting quality and improving drivers' visual performance; as a result, it contributes to lower the fluctuation of drivers' workload and get a smooth traffic flow, and ultimately this technically ensures physical and mental health of drivers in a tunnel area.

Visual health and prevalence of dry eye syndrome among university students in Iraq and Jordan.

Dry eye syndrome (DES), is a multifactorial disease that affects the ocular surface and contributes to the ocular symptoms. The COVID-19 pandemic influenced the general population and university students' health in different ways. The pandemic forced many people including university students around the world to use virtual platforms on their digital devices, such as computers and smartphones, to work from a distance. This study aimed to explore the visual health and prevalence of dry eye syndrome among university students in Iraq and Jordan. This was a cross-sectional study that was conducted in Iraq and Jordan using online questionnaire tool for the duration between November 2021 and January 2022. University students in Jordan and Iraq were invited to participate in this study and formed the study population. No restrictions on study level or field of study were applied. A previously developed and validated questionnaire tools were used in this study (National Eye Institute Visual Functioning Questionnaire - 25 (VFQ-25) and the Women's Health Study Questionnaire (WHS), which was developed by Schaumberg et al.). A total of 1,431 university students were involved in this study (1,018 students from Iraq, 71.1%). Around one third the study participants (29.0%) reported that have been diagnosed by a clinician as having dry eye syndrome. Around15.3% of the total study participants reported that they feel their eyes are dry (not wet enough) and 17.3% reported that they feel their eyes are irritated. Based on Women's Health Study Questionnaire (WHS) criteria, a total of 479 participants (33.4%) are symptomatically diagnosed with DES. Students aged 27-29 years, those at their fifth year of study, and those who wear contact lenses are at higher risk of developing DYS compared to others. Dry eye syndrome is common health problem among university students. Further studies are required to identify other risk factors associated with DES. Future research should focus on identifying strategies that could help reduce the risk of developing DES as a result of the inevitability of long-term use of digital devices among many categories of society, including university students.

Cyanidin-3-glucoside improves the barrier function of retinal pigment epithelium cells by attenuating endoplasmic reticulum stress-induced apoptosis.

Excessive exposure to blue light from smartphones, computers, and other video equipment causes retinal degeneration. Cyanidin-3-glucoside (C3G) exerts protective effects on retinal cells. However, the mechanism by which C3G enhances the barrier function of retinal pigment epithelial (RPE) cells remains unclear. This study investigated the effects of C3G on blue light-irradiated A2E-containing RPE cells and explored whether or not the endoplasmic reticulum (ER) stress and downstream nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathways are involved in the mechanism. Results showed that C3G (10 and 25 µM) observably increased the viability and inhibited the apoptosis of RPE cells. Furthermore, C3G enhanced the barrier function of RPE cells and upregulated the expression of tight junction proteins. Blue light irradiation triggered ER stress, but C3G significantly suppressed the PERK/eIF2α/ATF4/CHOP pathway and maintained normal ER morphology in RPE cells. C3G also activated the Nrf2 pathway to promote RPE survival, which was independent of ER stress modulating Nrf2 activity. This study suggests that C3G promotes the barrier function of RPE cells by regulating ER stress-induced apoptosis, thereby offering a new approach to preventing retinal diseases. Thus, C3G is a potential functional food ingredient to improve visual health.

Impact of a culturally tailored informative video on cervical cancer: a pilot study with Amazonian women in treatment for cervical cancer.

The present study is a randomised pilot study that evaluated a culturally tailored video promoting information about cervical cancer (CC), developed with Amazonian women in treatment for CC. The sample included 63 patients in treatment for CC who were randomly assigned to three groups of 21 patients. The experimental group watched an informative video about CC. The active control group watched a video on healthy habits and the passive control group received no intervention. The groups were compared in terms of change in knowledge and illness perceptions, over time. The results showed that the experimental group was the only one with a significant increase in knowledge (ß = .166; p = .03) that was not maintained over time (ß = -.195; p = .04). Threatening illness perceptions about the disease increased in all groups over time (ß = .105; p = .001). Future studies should replicate the results testing the efficacy of an audiovisual strategy in a larger sample, in health services that serve populations with similar social and cultural characteristics. This study emphasises the importance of interprofessional oncology teams providing clear information regarding CC, during all stages of the disease, and patients' treatment.Impact StatementWhat is already known on this subject? Latin American countries, such as Brazil, the low coverage of screening for CC can be related to the low education of women and their difficulty of access to health care. Hence, educational interventions may be a good strategy to reinforce the importance of screening and increase knowledge about illness prevention and treatment.What the results of this study add? An audiovisual informational intervention on CC was developed, addressing prevention, causes, control, consequences and treatment while respecting the patients' cultural and social reality through an approach that is simple and easy to understand. The group that watched the informative video was the only one that increased knowledge, revealing that it was a good CC informational strategy.What are the implications of these findings for clinical practice and/or further research? This study confirmed the importance of developing informational and educational strategies that are appropriate to patients' social and cultural reality. The video is now available to health teams in primary, secondary and tertiary care units, as a strategy for health promotion and CC prevention.

Emergent gender myths: A social semiotic analysis of visual images in health communication for development

Background@#Visual images are used to communicate health effectively, yet visual gender representation in the context of health is not well established as most studies focused on effectiveness, awareness, adoption, or behavior change. @*Objectives@#This study explored emerging gender myths in visual images used to communicate reproductive health, maternal health, family and nutrition, breastfeeding, and childcare with the premise that visuals may shape notions of gender roles and identities. @*Methodology@#Selected images from flipcharts produced by development communication practitioners were analyzed using Kress and Van Leeuwen's social semiotics (2006). Interpretive visual analysis was used to analyze visual impacts (denotation) and cultural meanings (connotation) by Barthes' Order of Signification, and gender roles and identity naturalized by the images. @*Results@#Images for health communication used more women as subjects relative to the topics that are primarily women's concern. The subject's gaze were indirect offered as items of information, showing a relation of symbolic equality, and implying that health topics are part of the social discourse. Visual impacts and cultural meanings of images uncovered myths that embody the roles, and identities, and social expectations of men and women in health. Emerging gender myths have to do with anatomy, mainly as basis for the role, identity, and expectations, especially of women as main actors in health. @*Conclusion@#This study reveals that gender roles and identities portrayed in health are still universal and are not historically and culturally contingent.

Student Health Implications of School Closures during the COVID-19 Pandemic: New Evidence on the Association of e-Learning, Outdoor Exercise, and Myopia.

The coronavirus disease 2019 (COVID-19) pandemic forced many education systems to consider alternative remote e-learning modalities, which have consequential behavioral and health implications for youth. In particular, increased e-learning engagement with digital screens and reduction in outdoor activities are two likely channels posing adverse risks for myopia development. This study investigated the association between e-learning screen use, outdoor activity, lighting condition, and myopia development among school-age children in China, during the first wave of the COVID-19 pandemic. Data were collected from 3405 school-age children attending primary, lower-secondary, and upper-secondary schools in China. Univariate parametric and nonparametric tests, and multivariate logistic regression analysis were used. Findings show that each diopter hour increase in daily e-learning screen use is significantly associated with progression of myopia symptoms (OR: 1.074, 95% CI: 1.058-1.089; p < 0.001), whereas engaging in outdoor exercise four to six times per week (OR: 0.745, 95% CI: 0.568-0.977; p = 0.034) and one to three times per week (OR: 0.829, 95% CI: 0.686-0.991; p = 0.048) is associated with a lower likelihood of myopia progression than none at all. In addition, we found that indoor lighting that is either "too dim" (OR: 1.686, 95% CI: 1.226-2.319; p = 0.001) or "too bright" (OR: 1.529, 95% CI: 1.007-2.366; p = 0.036) is significantly associated higher likelihood of myopic symptoms. Findings in this study uncover the less observable vision consequences of the COVID-19 pandemic on youths through digital online learning and highlight the importance of considering appropriate mitigation strategies to deal with this emerging public health challenge.

Comparative evaluation of audio-visual and verbal education method on OHRQoL, dental anxiety, dental neglect of diabetes mellitus patients attending a teaching hospital in India.

AIM: The aim of this study was to compare audio-visual and verbal education on oral health related quality of life, dental anxiety and dental neglect, on diabetes mellitus patients attending Teerthanker Mahaveer Hospital, Moradabad. MATERIALS AND METHOD: The current longitudinal interventional study was conducted to check the efficiency of audio-visual and verbal education on OHRQoL, Dental anxiety and dental neglect, on diabetes mellitus patients attending Teerthanker Mahaveer Hospital, Moradabad, U.P., India. A 14-item questionnaire, OHIP-14, with emphasis on seven proportions of impact was used to collect information on OHRQoL. Corah Dental Anxiety Scale (DAS) will be used to collect data on Dental Anxiety. A prevalidated revised proforma of Dental Neglect Scale (DNS) was used to gather information on Dental Neglect. The questionnaire was a six-question instrument related to dental problems. After collecting the initial baseline data, the sample was divided into two groups: verbal education group (n = 1030) and audio-visual education group (n = 1030). Then oral health education (OHE) was provided verbally to Group I patients and OHE with audio-visual aids was given to Group II patients visiting Teerthanker Mahaveer Hospital. OHE was repeated every 2 months. At every 6, 12 and 18 months, questionnaire was repeated to evaluate the effectiveness of OHE. Inspection will be conducted under natural daylight in hospital premises. To avoid the disruption while conducting the examination, adequate supply of instruments was taken. Instruments were sterilized by autoclaving in the college. RESULTS: A total of 1926 patients attended all the follow-up and review examinations. Subject dropout for Group I was 2% with 1009 at 6th month; 3% with 978 at 12th month and 1% with 967 at 18th month. Subject dropout rate for Group II was 3% with 999 at 6th month; 0% with 999 at 12th month and 4% with 959 at 18th month. The difference of subject dropout among the groups was not statistically significant (P = 0.23). Group mean total OHIP-14 score after 18 months was recorded as 15.36 ± 8.61, whereas in Audio-visual education group mean total OHIP-14 score after 18 months was recorded as 14.42 ± 7.59. At the end of study mean DAS score for DAS ≥15 (severe anxiety) was found to be 1.95 ± 2.18 in verbal education group, whereas in audio-visual education group mean DAS score for DAS ≥15 (severe anxiety) was found to be 2.24 ± 1.98. At the end of the study mean DN score for DNS ≥15 (severe Dental Neglect) was found to be 3.54 ± 2.63 in verbal education group, whereas audiovisual education group mean DN score for DNS ≥15 (severe Dental Neglect) was found to be 2.59 ± 2.75. CONCLUSION: The quality of life is a factor that can be considerably affected by oral health, which in turn reflects the general health of an individual. The main part of oral disease prevention is done by use of personal oral hygiene measures and maintaining oral hygiene. It is the duty of dental professionals to motivate, show and instruct patients to maintain appropriate oral health and oral hygiene. The study concludes that the program of this kind may be beneficial in improving many dimensions of dental health of an individual that includes physical health, emotional well-being, OHRQoL, inter-personal relationship and the fear related to dental treatment.

The Role of Barriers and Community-Based Education in Compliance to Regular Eye Exams in New York City's Harlem Community.

Background The American Optometric Association (AOA) recommends adults between the ages of 18 to 65 have an eye exam every two years while older individuals or those who utilize vision correction should have yearly exams. Previous vision screenings throughout New York City's Harlem community determined that 60% warranted referral to an ophthalmologist.  Objective As delayed vision screening could potentially leave a sight-threatening condition undiagnosed for many years, the objective of this study was to identify barriers to regular eye examinations. Methods A voluntary anonymous survey was verbally administered and recorded at free medical student-run vision screenings throughout multiple Harlem community health fairs. Data gathered included demographics, insurance coverage, comfort with an eye exam, and knowledge associated with an ophthalmologist eye exam. As a strategy to curtail the frequency of non-compliance to regular eye examinations, all participants were then educated about knowledge of ocular examinations and assured about uncertainties. Comfort levels were remeasured after education to determine the effectiveness and impact of community-based education. Results One hundred surveys fit the inclusion criteria. Of the participants with suboptimal knowledge of an eye exam (n=41), 32% were more comfortable after education and assurance versus 3% of the optimal knowledge participants (n=59). Of the participants with non-compliance to regular eye exams (n=39), 41% had suboptimal knowledge and 23% were more comfortable after education versus 33% and 10% of the compliant participants (n=61), respectively. Participants with suboptimal knowledge were 20.9% more likely to be noncompliant with regular eye examinations and at the same time, 18.1% more likely to have increased comfort after education and assurance than those with optimal knowledge. Of the participants without medical insurance (n=15), 67% were noncompliant with regular eye examinations and 60% had suboptimal knowledge versus 34% and 38% of the insured participants (n=85), respectively. Participants with medical insurance were 23.8% more likely to be compliant with regular eye examinations than those without medical insurance. Conclusion Measured perceptions of ophthalmology in New York City's Harlem community solidifies a lack of education as a clear barrier against proper vision care. Lack of health insurance coverage also contributed to decreased participation in regular eye examinations but to a lesser extent than education. These results suggest that empowering people through education can significantly improve compliance with regularly scheduled eye exams, thus improving the overall visual health of this minority-rich community.

Digging Deeper for the Eye Proteome in Vitreous Substructures: A High-Resolution Proteome Map of the Normal Human Vitreous Base.

Mapping the normal eye proteome in healthy persons is essential to unravel the molecular basis of diseases impacting visual health. The vitreous occupies a large portion of the human eye between the lens and the retina and plays a significant role in vitreoretinal diseases as well as maintaining clarity in the visual field, providing nutrition to the lens, and protecting the eye from mechanical shocks. It comprises four distinct anatomical regions, namely the vitreous core, vitreous cortex, vitreous base, and anterior hyaloid. Among these, the vitreous is attached to other substructures in the eye by the vitreous base, which is its strongest point of attachment. Alterations in vitreous substructures have been reported in several vitreoretinal disorders, including vitreomacular traction, vitreoretinopathies, and age-related macular degeneration. There has been limited knowledge on proteomics variations at a resolution of vitreous substructures, including the functionally and pathophysiologically significant vitreous base. We report here new findings on the proteome map of the vitreous base in normal healthy tissue. We employed a global, unbiased proteomic profiling approach resulting in the identification of 6511 proteins. Of these, 302 proteins were involved in metabolic processes essential for energy utilization. Moreover, we identified several structural and nutrient transport proteins. Notably, the identified proteome repertoire indicates that the vitreous base might possess additional physiological functions and may not be a passive structure. This study constitutes the most extensive catalog of vitreous base proteins to our knowledge and offers novel insights as a baseline for future studies on the pathobiology of various eye diseases. These data also invite us to consider a potentially more active functional role for the vitreous base in eye physiology and visual health.

Are Your Eyes "on the Road"? Findings from the 2019 National Study on Vision and Driving Safety in Spain.

Background: Vision is an undisputable contributor to the explanation of many human-factor related traffic crashes happening every day. The Inland Transport Committee (ITC), the United Nations regulatory platform, included on 1st April 2020 special action on the vision of road users inside the ITC Recommendations for Enhancing Road Safety Systems. The results of this wide-scale study on drivers' vision health conducted in Spain perfectly illustrates the need of global action and its potential impact on the public health figures and the burden of potentially preventable traffic causalities. Objective: The aim of this study was to assess three key visual health issues (i.e., visual acuity, visual field campimetry and glare recovery) among Spanish drivers, in order to formulate implications and possible guidelines to enhance road safety. Methods: This cross-sectional study examined the visual health of a representative sample of 3249 drivers (70% females and 30% males) with a mean age of 41 (SD = 13) years, gathered from all the 17 autonomous communities of Spain. Results: The tests performed allowed to determine that 15% of Spanish drivers have a poor photopic vision, while 38% of them present an inadequate mesopic vision. Further, 23% of drivers have deficiencies in peripheric visual field campimetry, and the average time for full-vision recovery after a 10-s glare was 27 s. Sex, age and driver type (professional vs. non-professional) differences were found for the study variables. Conclusions: The findings of this study support the idea that certain demographic-based population groups of drivers present several unaddressed deficiencies and impairments in visual health. Overall an estimated 29.5% of Spanish drivers present visual issues, that need to be attended in order to enhance the prevention of driving crashes and the road safety of all road users.
