Exploring the Darkverse: A Multi-Perspective Analysis of the Negative Societal Impacts of the Metaverse.

The Metaverse has the potential to form the next pervasive computing archetype that can transform many aspects of work and life at a societal level. Despite the many forecasted benefits from the metaverse, its negative outcomes have remained relatively unexplored with the majority of views grounded on logical thoughts derived from prior data points linked with similar technologies, somewhat lacking academic and expert perspective. This study responds to the dark side perspectives through informed and multifaceted narratives provided by invited leading academics and experts from diverse disciplinary backgrounds. The metaverse dark side perspectives covered include: technological and consumer vulnerability, privacy, and diminished reality, human-computer interface, identity theft, invasive advertising, misinformation, propaganda, phishing, financial crimes, terrorist activities, abuse, pornography, social inclusion, mental health, sexual harassment and metaverse-triggered unintended consequences. The paper concludes with a synthesis of common themes, formulating propositions, and presenting implications for practice and policy.

Prevalence and risk factors of recurrent aphthous stomatitis among college students at Mangalore, India.

Background: Recurrent aphthous stomatitis (RAS) is one of the most common oral mucosal diseases affecting an approximate 25% of the world's population. Some common etiological factors are genetics, nutritional deficiencies, stress and immune dysfunction. There is currently no specific medication to treat the condition but RAS tends to heal by itself within a week or two. We aimed to explore about the prevalence and related risk factors of recurrent aphthous ulcers among college students aged 18-30 years who had been affected within the preceding six months prior to the study duration. Methods: A questionnaire survey was conducted among 681 students from four colleges in Mangalore, Karnataka, India after obtaining the approval for the same from the respective colleges. Consenting participants returned a survey containing various questions. The collected data was then analyzed using descriptive statistics. The study was approved by the Institutional Ethics Committee. Results: Of the 681 participants, 322 (47.2%) were affected with RAS in the past six months which included 131 (40.6%) males and 191 (59.3%) females. Single mouth ulcers were the most common presentation seen among the study participants (74.2%). Factors showing statistically significant association were: family history of RAS (P < 0.001), known diabetics (P < 0.001), history of smoking (P < 0.001), oral trauma (P < 0.001), history of wearing braces/dentures (P < 0.001) as well as those using toothpastes containing sodium lauryl sulphate (P < 0.001), stress and lack of sleep (P < 0.001). The most common form of medication used were topical agents (43.1%) (P < 0.001). Conclusions: There was a statistically significant association between the occurrence of RAS and family history of RAS, diabetes, smoking, history of braces/dentures, oral trauma, sodium lauryl sulphate toothpastes, lack of sleep, stress, menstruation, consumption of particular foods and beverages. Further research is needed in this field to truly understand the prevalence and risk factors of RAS and to help in discovering a treatment modality for this condition.

Assessment of the factors that affect the selection of a dentifrice among a population of 18-24-year-old students in Mangalore: A questionnaire survey.

Introduction: Bacterial plaque accumulation is the primary etiological factor for periodontal disease; hence, prevention of its accumulation is the cornerstone to any oral hygiene practice. Mechanical tooth cleaning by means of toothbrush and a dentifrice remains the most reliable and common method for controlling supragingival plaque. The objective of the study was to evaluate the factors considered while choosing a dentifrice and also to assess the role of socioeconomic status in determining these factors. Materials and Methods: This was a questionnaire study carried out among undergraduate students from the business and mass communication background of two private degree colleges in Dakshina Kannada, India. Two hundred and fifty-five students were included in the study. The questionnaire consisted of 24 close-ended questions. Results and Conclusion: The parameters of brand name, availability, and the flavor of the dentifrice are among the most accepted factors that a consumer takes into consideration in selecting a dentifrice. Parameters of influence (parents, colleagues, and celebrities), advertisement, and dentist recommendations of a dentifrice were also found to have a major influence on the consumer in selecting a dentifrice.

Preventing Early Childhood Caries through Oral Health Promotion and a Basic Package for Oral Care: A Pragmatic Trial.

Introduction: Untreated caries in mothers is one of the common risk factors for early childhood caries (ECC). Aim: The aim of the study was to investigate the impact of an oral health promotion program on ECC. Methodology: We conducted a pragmatic trial at 12 primary health centers in a rural community of India with 311 pregnant women using fluoride toothpaste, oral health information through pamphlets, and referral to urgent dental care or atraumatic dental treatment as the test intervention. Data were collected through structured interviews at baseline and oral examination of the children at 2 years of age. Results: Of the 311 women who participated, 274 children were followed up with at 2 years of age. ECC was low and comparable in both groups. When compared with the control group, significantly, more children from the intervention group were breastfed for over 6 months of age (P = 0.012) and consumed less sugar (P < 0.001). The number of mothers' decayed teeth (P = 0.01), children's sweet scores (P < 0.001), and the age at which brushing commenced for children (P = 0.04) increased the likelihood of tooth decay in children. Conclusion: The oral health promotion program had some beneficial effects in preventing caries in children when provided to pregnant women.

Overweight and Obese Status Is Not Associated With Disease Activity for Children and Adolescents With Newly Diagnosed Inflammatory Bowel Disease.

INTRODUCTION: Despite the high prevalence of pediatric obesity, its impact on Crohn's disease (CD) and ulcerative colitis (UC) activity remains poorly characterized. The aim of this study was to evaluate disease-related outcomes in overweight and obese children with CD and UC. METHODS: We conducted a retrospective cohort study using the ImproveCareNow Network, a multicenter registry of children with inflammatory bowel disease. We included children with newly diagnosed CD and UC enrolled in ImproveCareNow Network from September 2006 to December 2018 who had at least 1 follow-up visit 12-18 months after diagnosis. Patients were stratified into normal weight, overweight, or obese categories. Primary outcome was remission at 1 year based on physician's global assessment (PGA); key secondary outcomes included short pediatric CD activity index and pediatric UC activity index. RESULTS: There were 4,972 children included (70% CD). Compared with normal weight, obese and overweight children with CD did not have worse disease activity at 1 year based on PGA. However, obese children did have modestly worse disease activity based on short pediatric CD activity index (inactive 43% vs 58%, mild 48% vs 36%, and moderate-severe 9% vs 7% for obese vs normal weight, P < 0.01). For children with UC, there were no differences in disease activity at 1 year based on PGA or pediatric UC activity index. Logistic regression mirrored these findings. DISCUSSION: Obese and overweight children with newly diagnosed inflammatory bowel disease do not seem to have worsened disease activity at 1 year after diagnosis compared with normal weight children.

Single-Cell Analysis Reveals Unexpected Cellular Changes and Transposon Expression Signatures in the Colonic Epithelium of Treatment-Naïve Adult Crohn's Disease Patients.

BACKGROUND & AIMS: The intestinal barrier comprises a monolayer of specialized intestinal epithelial cells (IECs) that are critical in maintaining mucosal homeostasis. Dysfunction within various IEC fractions can alter intestinal permeability in a genetically susceptible host, resulting in a chronic and debilitating condition known as Crohn's disease (CD). Defining the molecular changes in each IEC type in CD will contribute to an improved understanding of the pathogenic processes and the identification of cell type-specific therapeutic targets. We performed, at single-cell resolution, a direct comparison of the colonic epithelial cellular and molecular landscape between treatment-naïve adult CD and non-inflammatory bowel disease control patients. METHODS: Colonic epithelial-enriched, single-cell sequencing from treatment-naïve adult CD and non-inflammatory bowel disease patients was investigated to identify disease-induced differences in IEC types. RESULTS: Our analysis showed that in CD patients there is a significant skew in the colonic epithelial cellular distribution away from canonical LGR5+ stem cells, located at the crypt bottom, and toward one specific subtype of mature colonocytes, located at the crypt top. Further analysis showed unique changes to gene expression programs in every major cell type, including a previously undescribed suppression in CD of most enteroendocrine driver genes as well as L-cell markers including GCG. We also dissect an incompletely understood SPIB+ cell cluster, revealing at least 4 subclusters that likely represent different stages of a maturational trajectory. One of these SPIB+ subclusters expresses crypt-top colonocyte markers and is up-regulated significantly in CD, whereas another subcluster strongly expresses and stains positive for lysozyme (albeit no other canonical Paneth cell marker), which surprisingly is greatly reduced in expression in CD. In addition, we also discovered transposable element markers of colonic epithelial cell types as well as transposable element families that are altered significantly in CD in a cell type-specific manner. Finally, through integration with data from genome-wide association studies, we show that genes implicated in CD risk show heretofore unknown cell type-specific patterns of aberrant expression in CD, providing unprecedented insight into the potential biological functions of these genes. CONCLUSIONS: Single-cell analysis shows a number of unexpected cellular and molecular features, including transposable element expression signatures, in the colonic epithelium of treatment-naïve adult CD.

Evaluation of Preclinical Task Based Learning program in Medical Education.

The conventional curriculum in preclinical medical education has a need for early clinical exposure programs that help in correlation of basic science data with clinical skills. This is helpful to develop clinical reasoning skills, problem-solving abilities, team work, communication skills and overall attitudes and behaviour relevant for a healthcare provider. Preclinical task based learning (TskBL) is an active learning strategy in which the focus for the first year medical student is a real task done by a doctor. In this strategy the student-doctors undergo a standardized patient encounter and discuss the learning issues related to the task in the first year of medical school. The current study is focussed on the student perception of the effectiveness of task based learning module.The TskBL was conducted among first year medical students for nine topics that are commonly encountered in the clinics. After TskBL was planned and implemented the evaluation of the modules was done using focus group discussions. The students highlighted the importance of standardized patients in the TskBL strategy in providing early clinical exposure in preclinical medical education. They reported its usefulness gaining essential knowledge, skills and attitudes for medical learning. They reported positive outcomes of module design and processes and activities in TskBL. Based on the negative aspects of the modules, future improvement was suggested in improving the usefulness of standardized patient encounter. This study showed the novice learners' outlook of the potency of TskBL for several other topics of clinical relevance to provide early clinical exposure in medical schools.

A task-based learning strategy in preclinical medical education.

Preclinical task-based learning (TskBL) is a simulated learning approach in which the focus for students is a real task done by a medical professional. TskBL includes standardized patient encounters and is helpful to provide early clinical exposure. Our study aimed at planning, implementing, and assessing TskBL among first-year medical students and comparing it to the conventional method of tutorials in the physiology MBBS curriculum. This is a nonequivalent group quasi-experimental study approved by the institutional ethics committee. TskBL was conducted for seven topics among first-year medical students of Kasturba Medical College, Mangalore for three academic years. Participants were divided into a TskBL group and a control group. Both groups attended the theory classes in physiology, practical sessions, and clinical examinations concerning the tasks. After this, the TskBL group underwent TskBL, and the control group underwent tutorials. Pretest and posttest assessments were conducted by using a multiple choice question (MCQ) test and objective structured clinical examinations (OSCEs).The mean TskBL scores for MCQ (exception: hypertension, myasthenia gravis, and chronic obstructive pulmonary disease) and OSCE (exception: anemia and hypertension) were significantly higher than the tutorial group. Pretest and posttest scores revealed significantly higher MCQ and OSCE scores for TskBL (exception: MCQ score for hypertension and chronic obstructive pulmonary disease). The tutorial group did not show a significant improvement in test scores for all the tasks. The TskBL strategy could be used for topics that are likely to be encountered by the students during clinical attachments. Small group teaching can include TskBL in preference to tutorials to provide early clinical exposure in medical schools.

Integrating Research into Undergraduate Medical Education Curriculum: A 20-year Experience from a Medical School in Coastal South India.

Research is the key to advancement in medical science. Medical school can nurture the skill of research right from the under graduation. Research forms an integral part of the medical curriculum in western countries. We attempted the same in our medical school in India. We developed a structured research methodology program, which was implemented in the undergraduate (UG) curriculum in two phases. Phase I focuses on research methodology and Phase II on manuscript writing. With the implementation of a competency-based medical education curriculum (CBME), we have extended the research methodology program with manuscript writing and introduction to systematic reviews, which is being offered as electives to UG medical students in the third professional year. Our experience in training students at an UG level has been immensely satisfying. We hope that this article will help other medical schools to adopt a similar method of training UG medical students in research methodology and scientific medical writing.

The Effect of Socioeconomic Factors and Indoor Residual Spraying on Malaria in Mangaluru, India: A Case-Control Study.

India faces 0.5 million malaria cases annually, including half of all Plasmodium vivax malaria cases worldwide. This case-control study assessed socioeconomic determinants of urban malaria in coastal Mangaluru, Karnataka, southwestern India. Between June and December 2015, we recruited 859 malaria patients presenting at the governmental Wenlock Hospital and 2190 asymptomatic community controls. We assessed clinical, parasitological, and socioeconomic data. Among patients, p. vivax mono-infection (70.1%) predominated. Most patients were male (93%), adult (median, 27 years), had no or low-level education (70.3%), and 57.1% were daily labourers or construction workers. In controls (59.3% male; median age, 32 years; no/low-level education, 54.5%; daily labourers/construction workers, 41.3%), 4.1% showed asymptomatic Plasmodium infection. The odds of malaria was reduced among those who had completed 10th school grade (aOR, 0.3; 95% CI, 0.26-0.42), lived in a building with a tiled roof (aOR, 0.71; 95% CI, 0.53-0.95), and reported recent indoor residual spraying (aOR, 0.02; 95% CI, 0.01-0.04). In contrast, migrant status was a risk factor for malaria (aOR, 2.43; 95% CI, 1.60-3.67). Malaria in Mangaluru is influenced by education, housing condition, and migration. Indoor residual spraying greatly contributes to reducing malaria in this community and should be promoted, especially among its marginalised members.

Health Maintenance Consensus for Adults With Inflammatory Bowel Disease.

BACKGROUND: With the management of inflammatory bowel disease (IBD) becoming increasingly complex, incorporating preventive care health maintenance measures can be challenging. The aim of developing these updated recommendations is to provide more specific details to facilitate their use into a busy clinical practice setting. METHOD: Fifteen statements were formulated with recommendations regarding the target, timing, and frequency of the health maintenance interventions in patients with IBD. We used a modified Delphi method and a literature review to establish a consensus among the panel of experts. The appropriateness of each health maintenance statement was rated on a scale of 1 to 5 (1-2 as inappropriate, and 4-5 as appropriate) by each panelist. Interventions were considered appropriate, and statements were accepted if ≥80% of the panelists agreed with a score ≥4. RESULTS: The panel approved 15 health maintenance recommendations for adults with IBD based on the current literature and expert opinion. These recommendations include explicit details regarding specific screening tools, timing of screening, and vaccinations for adults with IBD. CONCLUSIONS: Patients with IBD are at an increased risk for infections, malignancies, and other comorbidities. Given the complexity of caring for patients with IBD, this focused list of recommendations can be easily incorporated in to clinical care to help eliminate the gap in preventative care for patients with IBD.

Increased colonic expression of ACE2 associates with poor prognosis in Crohn's disease.

The host receptor for SARS-CoV-2, angiotensin-converting enzyme 2 (ACE2), is highly expressed in small intestine. Our aim was to study colonic ACE2 expression in Crohn's disease (CD) and non-inflammatory bowel disease (non-IBD) controls. We hypothesized that the colonic expression levels of ACE2 impacts CD course. We examined the expression of colonic ACE2 in 67 adult CD and 14 NIBD control patients using RNA-seq and quantitative (q) RT-PCR. We validated ACE2 protein expression and localization in formalin-fixed, paraffin-embedded matched colon and ileal tissues using immunohistochemistry. The impact of increased ACE2 expression in CD for the risk of surgery was evaluated by a multivariate regression analysis and a Kaplan-Meier estimator. To provide critical support for the generality of our findings, we analyzed previously published RNA-seq data from two large independent cohorts of CD patients. Colonic ACE2 expression was significantly higher in a subset of adult CD patients which was defined as the ACE2-high CD subset. IHC in a sampling of ACE2-high CD patients confirmed high ACE2 protein expression in the colon and ileum compared to ACE2-low CD and NIBD patients. Notably, we found that ACE2-high CD patients are significantly more likely to undergo surgery within 5 years of CD diagnosis, and a Cox regression analysis found that high ACE2 levels is an independent risk factor for surgery (OR 2.17; 95% CI, 1.10-4.26; p = 0.025). Increased intestinal expression of ACE2 is associated with deteriorated clinical outcomes in CD patients. These data point to the need for molecular stratification that can impact CD disease-related outcomes.

Perception and practice regarding infection control measures in Radiology department during pre-COVID and COVID times-A survey among radiologists and a review of current concepts and literature.

AIM: In this study, we aim to evaluate the perception and practice of IPC measures by Radiologists during pre-COVID and present COVID times, while conducting a thorough review of current concepts and literature, to provide a standard operating procedure (SOP) for radiology operations. METHODS: This study was conducted by Department of Radiodiagnosis and Imaging, Kasturba Medical College, MAHE, Mangalore. After obtaining approval from the institutional ethics committee, and other required permissions, the Google form questionnaire was sent to 350 Radiologists via email and text during the period of May 2020. Data was collected by time-based sampling in the period of fifteen days during the end of the total lockdown time. RESULTS: 54% (n = 152) reported never attending a training session on (Infection Prevention & Control) IPC prior to the COVID-19 outbreak. The perception regarding IPC were found to be good among radiologists as majority of the respondents were correctly able to answer questions regarding IPC. 86% (n = 152) of the respondents believed that their knowledge on IPC has improved during the COVID-19 pandemic. However, it was revealed that majority of the respondents only started to practice appropriate contact and droplet / procedural precautions only after the COVID-19 outbreak. CONCLUSION: The present COVID-19 scenario coupled with the lack of knowledge and training regarding IPC amongst radiologists evident from the results of our survey, highlights the need for proper training and establishing standard operating procedures and best practices in IPC pertinent to modern radiology practice.

Digitized smart surveillance and micromanagement using information technology for malaria elimination in Mangaluru, India: an analysis of five-year post-digitization data.

BACKGROUND: Malaria control system (MCS), an Information technology (IT)-driven surveillance and monitoring intervention is being adopted for elimination of malaria in Mangaluru city, Karnataka, India since October 2015. This has facilitated 'smart surveillance' followed by required field response within a timeline. The system facilitated data collection of individual case, data driven mapping and strategies for malaria elimination programme. This paper aims to present the analysis of post-digitization data of 5 years, discuss the current operational functionalities of MCS and its impact on the malaria incidence. METHODS: IT system developed for robust malaria surveillance and field response is being continued in the sixth year. Protocol for surveillance control was followed as per the national programme guidelines mentioned in an earlier publication. Secondary data from the malaria control system was collated and analysed. Incidence of malaria, active surveillance, malariogenic conditions and its management, malariometric indices, shrinking malaria maps were also analysed. RESULTS: Smart surveillance and subsequent response for control was sustained and performance improved in five years with participation of all stakeholders. Overall malaria incidence significantly reduced by 83% at the end of 5 years when compared with year of digitization (DY) (p < 0.001). Early reporting of new cases (within 48 h) was near total followed by complete treatment and vector control. Slide positivity rate (SPR) decreased from 10.36 (DY) to 6.5 (PDY 5). Annual parasite incidence (API) decreased from 16.17 (DY) to 2.64 (PDY 5). There was a negative correlation between contact smears and incidence of malaria. Five-year data analyses indicated declining trends in overall malaria incidence and correlation between closures by 14 days. The best impact on reduction in incidence of malaria was recorded in the pre-monsoon months (~ 85%) compared to lower impact in July-August months (~ 40%). CONCLUSION: MCS helped to micromanage control activities, such as robust reporting, incidence-centric active surveillance, early and complete treatment, documentation of full treatment of each malaria patient, targeted mosquito control measures in houses surrounding reported cases. The learnings and analytical output from the data helped to modify strategies for control of both disease and the vector, heralding the city into the elimination stage.

Increased Colonic Expression of ACE2 Associates with Poor Prognosis in Crohn's disease.

BACKGROUND AND AIMS: The host receptor for SARS-CoV-2, angiotensin-converting enzyme 2 (ACE2), is highly expressed in small intestine. Our aim was to study colonic ACE2 expression in Crohn's disease (CD) and non-inflammatory bowel disease (non-IBD) controls. We hypothesized that the colonic expression levels of ACE2 impacts CD course. METHODS: We examined the expression of colon ACE2 using RNA-seq and quantitative (q) RT-PCR from 69 adult CD and 14 NIBD control patients. In a subset of this cohort we validated ACE2 protein expression and localization in formalin-fixed, paraffin-embedded matched colon and ileal tissues using immunohistochemistry. The impact of increased ACE2 expression in CD for the risk of surgery was evaluated by a multivariate regression analysis and a Kaplan-Meier estimator. To provide critical support for the generality of our findings, we analyzed previously published RNA-seq data from two large independent cohorts of CD patients. RESULTS: Colonic ACE2 expression was significantly higher in a subset of adult CD patients (ACE2-high CD). IHC in a sampling of ACE2-high CD patients confirmed high ACE2 protein expression in the colon and ileum compared to ACE2-low CD and NIBD patients. Notably, we found that ACE2-high CD patients are significantly more likely to undergo surgery within 5 years of diagnosis, with a Cox regression analysis finding that high ACE2 levels is an independent risk factor (OR 2.18; 95%CI, 1.05-4.55; p=0.037). CONCLUSION: Increased intestinal expression of ACE2 is associated with deteriorated clinical outcomes in CD patients. These data point to the need for molecular stratification that may impact CD disease-related outcomes.
