The effects of children receiving the influenza vaccination in comparison to ...KaralynGonzalez
The document discusses a presentation given by Karalyn Gonzalez on the effects of children receiving the influenza vaccination compared to school absenteeism. The presentation defines what a vaccination is, states the research question as whether children who receive the flu vaccine will miss more or less school than unvaccinated children, and hypothesizes that vaccinated children will miss more days. It then reviews findings from three articles supporting that vaccinated children actually miss fewer school days and have lower absenteeism rates during flu season.
This document summarizes a rapid review on whether food service workers are a leading cause of norovirus outbreaks. Key findings include:
- Norovirus causes 65% of foodborne illnesses in Canada, with at least 1 outbreak reported daily. However, many go unreported.
- Approximately 90% of foodborne norovirus outbreaks originate from food preparation settings like restaurants.
- Infectious food workers account for around 70% of outbreaks, often from bare hand contact with ready-to-eat foods.
- Only 1 in 5 food workers who were vomiting or had diarrhea reported staying home from work. Job protection and financial security influence this decision.
- Food preparation policies need to ensure
This document presents information on norovirus and its impact on food service workers. It summarizes that norovirus causes most foodborne illnesses annually and the majority of outbreaks originate from food preparation settings. Infectious food workers account for about 70% of norovirus outbreaks from food. The document also proposes research on whether the number of paid sick days influences a food worker's decision to stay home when sick.
Rising air pollution levels in Chennai and Coimbatore have led to air quality standards exceeding safe levels. This air pollution, combined with airborne infections, has resulted in increased cases of prolonged cough, respiratory infections, and sore throat pain. A recent survey found that 50% of respondents suffered from sore throat pain, with many experiencing sore throats once a year or more. To address this issue, a new throat spray containing antiseptics and a local anesthetic is being introduced to directly treat throat infections and relieve sore throat pain in a single use without side effects.
The Eliminate Dengue project, led by researchers at the University of Queensland, received approval to begin field trials in January 2011 to test a new biological approach using Wolbachia bacteria to control dengue fever. The goal is to introduce Wolbachia into mosquito populations to block virus transmission and provide a long-term, self-sustaining solution to the global burden of the mosquito-borne disease. The trials in North Queensland aim to determine how well the method can establish itself in wild mosquito populations.

This document discusses factors that affect the incidence and prevalence of periodontal diseases. It identifies three main categories of factors: host factors, agent factors, and environmental factors. Some key host factors discussed include age, sex, oral hygiene, socioeconomic status, tobacco use, general health conditions like diabetes, and nutrition. Agent factors refer mainly to bacteria and calculus. Environmental factors examined include geographic distribution, fluoride concentration in water, and aspects of the oral environment like prosthetic restorations and dental caries.
This document discusses the relationship between oral inflammatory diseases and systemic conditions. It begins with the historical background of this topic dating back to ancient Greece. It then defines key terms like "focal infection" and describes the pathogenesis of oral diseases like periodontitis. Periodontitis involves a polymicrobial biofilm that triggers an inflammatory host response. This systemic inflammation can influence distant target tissues through mechanisms like bacteremia, circulating inflammatory mediators, immune cell trafficking, and trained myelopoiesis. Specific oral diseases discussed that may impact systemic health include periodontitis and apical periodontitis. Target tissues discussed that may be affected include the cardiovascular, digestive, and nervous systems.

This document discusses risk factors, determinants, indicators, and predictors for periodontal disease. It identifies the major risk factors as smoking, diabetes, and pathogenic bacteria. It also discusses genetic factors, age, gender, socioeconomic status, and stress as risk determinants. HIV/AIDS, osteoporosis, and infrequent dental visits are provided as examples of risk indicators. Previous history of periodontal disease and bleeding on probing are given as examples of risk predictors. The document concludes by noting that clinical risk assessment involves collecting data on a patient's medical history, dental history, and clinical presentation and analyzing this using a computer-based tool to identify patients at risk of periodontal disease.
Fortunately we are not alone and we provide residence to numerous microbial
communities comprising of bacterial species. The human body is made up of 10 14 cells of which
only 10% are mammalian and the remainder is contributed by the microorganisms that make up
the resident micro flora of the host. Normal microbial flora is a term that denotes the population
of microorganism that inhabit the skin and mucous membranes of healthy normal persons.
Numerous bacterial species colonize the mouth, upper airways, skin, vagina and intestinal tract
of humans where each one have a unique site specific fingerprint made of distinct microbe with
high level of diversity which is still unexplained.These microorganism are inhabit in the oral
cavity and their unavoidable interrelationships are essential component in maintaining
homeostasis between health and disease moreover the skin and mucous membrane always harbor
variety of organisms and they can be further categorized into two groups. One is the resident
flora which consists of relatively fixed type of microorganisms regularly found in given area at a
given age, and promptly gathers and re-establishes itself even if it is disturbed. The other one is
the transient flora, consist of non-pathogenic or potentially pathogenic microorganisms that
inhabit skin or mucous membrane for hours, days or week and it is derived from the environment
that does not produce disease and does not have the capacity to reestablish permanently on the
surface. However if the resident flora is disturbed, transient microorganisms may get colonized,
proliferate and produce disease. This indigenous microbiota plays an important role in health and
diseases of humans and contributing to the development of the immune system and provides
resistance to colonization by pathogenic microorganisms. Thereby the presentation is intended to
review on the importance and thrust areas of oral microbiome in health and disease.
Comparative Effects of Chewing Gums in Oral Health: An Original ResearchDrHeena tiwari
This study assessed the effects of sugar-free chewing gum on oral health by comparing plaque index and DMFT scores between patients who chewed gum daily versus a control group. Forty patients were divided into two groups - one using sugar-free gum for 20 minutes daily and a control group. Plaque index and DMFT scores were assessed monthly for both groups. The gum group showed significantly lower plaque accumulation and fewer caries incidents compared to the control group after two months. However, the benefits decreased after longer use, possibly due to decreased compliance. The study concluded that sugar-free gum can improve oral health when used regularly as an adjunct to brushing and flossing by stimulating saliva and reducing plaque and caries risk.
Impact of periodontal infection on systemic health By Dr Sachin RathodDr Sachin Rathod
The document discusses the relationship between periodontal disease and diabetes. It notes that periodontitis is associated with gram-negative bacteria in subgingival plaque. Diabetes can increase the risk of periodontitis by impairing the immune response and altering collagen metabolism. Persistent infection from periodontal pathogens may increase insulin resistance in diabetes. Treatment of periodontitis in diabetics through nonsurgical and antibiotic methods has been shown to improve glycemic control and periodontal health. Maintaining periodontal health is important for optimal management of diabetes.
The document discusses the roles of probiotics, prebiotics, and synbiotics supplementation in improving the gut microbiota of stunted children. It provides background on gut microbiota in early life and its importance. Scientific findings show probiotics may be more effective for undernourished children in restoring dysbiotic microbiota and affecting growth. Evidence for prebiotics and growth effects is limited. Synbiotics studies show benefits for weight but not height. More research is needed on gut-targeted interventions and their synergistic effects with nutrition programs in low-income countries. The document recommends combination trials and attention to antibiotic use and initial nutrition status.
This article reviews the relationship between oral health and diabetes mellitus. It discusses how diabetes can cause various oral health issues such as periodontitis, dental caries, oral mucosal diseases, and salivary dysfunction. Periodontitis is characterized by chronic inflammation and breakdown of tissues around the teeth. It affects 50-90% of adults and is considered the 6th complication of diabetes. Patients with diabetes are also more susceptible to dental caries, opportunistic fungal infections like candidiasis, and have reduced salivary flow that increases oral dryness. The review concludes that diabetes has adverse effects on oral health and dental care should be an important part of managing diabetes to improve patients' well-being and quality
Diabetic patients knowledge, attitude and practice toward oral healthAlexander Decker
This study assessed the knowledge, attitudes, and practices of 612 diabetic patients in Abha City, Saudi Arabia regarding their oral health. The results showed that over half of patients were unaware of their increased risk of oral diseases as diabetics. Less than half knew that diabetes can cause dental caries and gingivitis. While patients' oral hygiene practices were generally good, their knowledge about the oral health risks of diabetes was deficient. The study highlights the need for better patient education on maintaining oral health and the link between diabetes and oral diseases.
Probiotics goes beyond digestive and immune health. At the recent Microbiome R&D and Business Collaboration Congress: Asia, DuPont Nutrition & Health shared on how probiotics can influence vaginal microbiota and provide positive health benefits such as weight management for the user.

This document discusses the epidemiology of dental caries. It identifies key host, agent, and environmental factors that contribute to caries development, including age, diet, bacteria like Streptococcus mutans, and fluoride exposure. The global distribution of caries has changed over time, with prevalence historically higher in developed nations due to diets high in refined carbohydrates, though patterns are changing as diets worldwide become more cariogenic. Socioeconomic status, nutrition, and oral hygiene also impact caries risk.

Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
Current Ms word generated power point presentation covers major details about the micronuclei test. It's significance and assays to conduct it. It is used to detect the micronuclei formation inside the cells of nearly every multicellular organism. It's formation takes place during chromosomal sepration at metaphase.
2. • infection that damages
the gingiva and alveolar
bone
What is periodontitis?
1. Van Dyke et al., 2014
2. CDC, 2012 Lee, 2017
• 47.2% of the population
above 30 has some
form of periodontitis
• multistage disease
3. 2 key components:
Pathogenesis of Periodontitis
Dominy et al., 2019 Figuerdo et al., 2019
Microbial shift/Dysbiosis
Host Inflammatory pathways
4. ● essentially a “microbial shift”/dysbiosis occurs
changing a healthy oral microbiome to be
pathogenic
● changes symbiotic host-microbe relationship to
pathogenic
Pathogenesis - Dysbiosis
Dominy et al., 2019
1. Teles et al., 2013
2. Zhang et al., 2019
3. Nath & Raveendran,
2013
● The oral microbiome houses ~700 types of
microbes
● symbiotic microbe-host relationship
● dysbiosis leads to a pathogenic relationship
● reduction of gram positive aerobes and over
abundance of gram negative anaerobes
● new microbial complexes → orange complex,
red complex
Orange complex bacteria:
Prevotella intermedia
Prevotella nigrescens
Prevotella micros
Fusobacterium
Campylobacter gracilis
Campylobacter rectus
Leptotrichia bucallis
Campylobacter showae
Campylobacter ochracea
Red Complex Bacteria:
Porphyromonas gingivalis
Treponema denticola
Tannerella forsythia
Eubacterium nodatum
Eubacterium saburreum
Aggregatibacter
actinomycetemcomitans
Prevotella melaninogenica
Prevotella micra
filifactor alocis
5. Pathogenesis - Inflammatory Response
Munoz-Carillo et al., 2018
Initial lesion - polymorphonuclear
leukocytes infiltrate the gingival
sulcus, increase in fibrin
Early lesion - accumulation of T
cells and cytokine release
Established lesion - dense
infiltration of T cells and B cells,
RANKL production
Advanced lesion - further
infiltration of B cells and T cells, B
cell autoantibodies breakdown
gingival tissue

7. What we Know So Far...
Presence of
Diabetes
Increased
incidence of
periodontitis
Exacerbates
progression of
periodontitis
WHY?
8. Question: What are the mechanisms and
factors that contribute to this increased
incidence and exacerbation of periodontitis
in diabetics?
9. Overlap Between Periodontitis and Diabetes
- dysbiosis of
the oral
microbiome
increase in red
and orange
complex
bacteria
Change in
oral
microbiome
Increase in
inflammation
Increased
incidence
of:
- nerve damage
- heart disease
- Kidney failure
Increased insulin
resistance chronic
inflammatory- immune
response
- inflammatory response
resulting in an increase in
cytokines, T cells, RANKL
etc
high glucose levels in
saliva which changes
nutrient sources for
bacteria
Diabetes Periodontitis
10. Hypothesis: Diabetes increases the
incidence of periodontitis by fostering an
oral microbiome that promotes
periodontitis pathogenesis and
exacerbates periodontitis by increasing the
stimulation of inflammatory pathways
11. Methods
• Worked with associate
librarian at UB’s
dental school
• The search resulted in
276 articles
• narrowed it down to
75
• Used only studies
using animal models
and gene sequencing
12. Is it the oral microbiome?
Hypothesis: Diabetes increases the incidence of periodontitis by fostering an oral
microbiome that promotes periodontitis pathogenesis and exacerbates
periodontitis by increasing the stimulation of inflammatory pathways
15. 1) Diabetes fosters an oral microbiome that has an
increased abundance of periodontopathogenic
bacteria in comparison to healthy individuals
2) Diabetics display less microbial diversity in the oral
microbiome
3) Those who have poorly controlled diabetes have a
more pathogenic oral microbiome than those with
well controlled diabetes
Findings:

16. Presence of Periodontitis
Increased
incidence of
periodontitis
Exacerbates
progression of
periodontitis
WHY?
Oral
Microbiome
increased abundance of
periodontopathogenic +
greater bone loss
17. But what about the inflammatory response?
● Oral microbiome
● Inflammatory
response
18. Hypothesis: Diabetes increases the
incidence of periodontitis by fostering an
oral microbiome that promotes
periodontitis pathogenesis and
exacerbates periodontitis by increasing the
stimulation of inflammatory pathways
