Pre-Weaned Calf Rearing on Northern Irish Dairy Farms-Part 2: The Impact of Hygiene Practice on Bacterial Levels in Dairy Calf Rearing Environments.

Pre-weaned dairy calves are very susceptible to disease in the first months of life due to having a naïve immune system and because of the numerous physiological stressors they face. Hygiene management is a key element in minimizing enteric disease risk in calves by reducing their exposure to pathogens. Samples of milk, concentrate feed and drinking water, boot swabs of bedding and swabs of feed equipment were collected from 66 dairy farms as part of a survey of calf rearing practice and housing design. All the samples were cultured to determine total viable counts (TVC), total coliforms (TCC) and Escherichia coli as indicators of hygiene. Target ranges for levels of TVC, TCC and E. coli were defined from the literature and the sample results compared against them. The TVC targets in milk, MR and water were <4.0 log10 CFU/mL. TCC and E. coli targets of <1.1 log10 CFU/mL (the detection limit) were used for milk, MR, concentrate feed and feeding equipment. For water, the TCC and E. coli targets were <1.0 log10 CFU/100 mL. The targets used for bedding boot swabs were <6.3 log10 TVC CFU/mL and <5.7 log10 TCC or E. coli CFU/mL. Farm management factors were included as fixed effects in a generalized linear mixed model to determine the probability of samples being within each hygiene indicator target range. Milk replacer samples obtained from automatic feeders were more likely to be within the TVC target range (0.63 probability) than those prepared manually (0.34) or milk samples taken from the bulk tank (0.23). Concentrate feed samples taken from buckets in single-calf pens were more likely to have E. coli detected (0.89) than samples taken from group pen troughs (0.97). A very small proportion of water samples were within the indicator targets (TVC 9.8%, TCC 6.0%, E. coli 10.2%). Water from self-fill drinkers had a lower likelihood of being within the TVC target (0.03) than manually filled buckets (0.14), and water samples from single pens were more likely to be within TCC target ranges (0.12) than those from group pens (0.03). However, all self-fill drinkers were located in group pens so these results are likely confounded. Where milk feeders were cleaned after every feed, there was a greater likelihood of being within the TVC target range (0.47, compared with 0.23 when not cleaned after every feed). Detection of coliforms in milk replacer mixing utensils was linked with reduced probability of TVC (0.17, compared with 0.43 when coliforms were not detected) and TCC (0.38, compared with 0.62), which was within target in feeders. Key factors related to increased probability of bedding samples being within TCC target range were use of group calf pens (0.96) rather than single-calf pens (0.80), use of solid floors (0.96, compared with 0.76 for permeable floors) and increased space allowance of calves (0.94 for pens with ≥2 m2/calf, compared with 0.79 for pens with <2 m2/calf). Bedding TVC was more likely to be within the target range in group (0.84) rather than in single pens (0.66). The results show that hygiene levels in the calf rearing environment vary across farms and that management and housing design impact hygiene.

Screw-retained internal connection zirconia CAD-CAM abutments in single implant reconstructions: Results of a 1-year prospective case series study.

To evaluate the clinical and radiographic outcomes of single-tooth implant restorations using one-piece, internally connected, screw-retained, computer-aided design and computer-aided manufactured monolithic zirconia restorations fabricated on regular diameter implants. Following a 2-stage surgical procedure, 22 implants placed in anterior and posterior areas in 21 partially edentulous patients (mean age of 55 years; 9 males/12 females) were evaluated in terms of plaque index, pocket probing depth, bleeding on probing, level of oral hygiene (OH), signs of mucositis/peri-implantitis, esthetic score (ES), gingival zenith position (GZP), papilla index score, the thickness of peri-implant gingiva, radiographic marginal bone loss, and technical complications. Implants and restorations were prospectively followed from the insertion of the restoration (baseline), up to 12-months post-loading. A 100% implant survival rate resulted after loading; one implant was lost before loading. Clinically, patients performed an adequate OH, and tissues were kept healthy. Probing depth showed a slightly lower value at baseline compared to any follow-up examination (2.26 [0.94] at baseline vs. 2.53 [0.66]mm at 12 months). ES, GZP, and the thickness of the peri-implant gingiva improved throughout the course of the study. Radiographically, average marginal bone level (MBL) was 0.40 (0.40)mm after 1-year follow-up with no differences in average MBL at all time points. Technically, after 1 year of clinical function, neither abutment fracture nor any other serious complications occurred. Hence, prosthetic reconstruction survival rate was 100%. Clinical outcomes of single-tooth implant restorations using internally connected, screw-retained, computer-aided design and computer-aided manufacturing monolithic zirconia abutments can be considered a reliable treatment alternative after 1-year clinical observation.

Does pre-COVID impulsive behaviour predict adherence to hygiene and social distancing measures in youths following the COVID-19 pandemic onset? Evidence from a South African longitudinal study.

BackgroundEngagement in protective behaviours relating to the COVID-19 pandemic has been proposed to be key to infection control. This is particularly the case for youths as key drivers of infections. A range of factors influencing adherence have been identified, including impulsivity and risk taking. We assessed the association between pre-COVID impulsivity levels and engagement in preventative measures during the COVID-19 pandemic in a longitudinal South African sample, in order to inform future pandemic planning.MethodsData were collected from N = 214 youths (mean age at baseline: M = 17.81 (SD = .71), 55.6% female) living in a South African peri-urban settlement characterised by high poverty and deprivation. Baseline assessments were taken in 2018/19 and the COVID follow-up was conducted in June–October 2020 via remote data collection. Impulsivity was assessed using the Balloon Analogue Task (BART), while hygiene and social distancing behaviours were captured through self-report. Stepwise hierarchical regression analyses were performed to estimate effects of impulsivity on measure adherence.ResultsSelf-rated engagement in hygiene behaviours was high (67.1–86.1% “most of the time”, except for “coughing/sneezing into one’s elbow” at 33.3%), while engagement in social distancing behaviours varied (22.4–57.8% “most of the time”). Higher impulsivity predicted lower levels of hygiene (β = .14, p = .041) but not social distancing behaviours (β = −.02, p = .82). This association was retained when controlling for a range of demographic and COVID-related factors (β = .14, p = .047) and was slightly reduced when including the effects of a life-skills interventions on hygiene behaviour (β = −.13, p = .073).ConclusionsOur data indicate that impulsivity may predict adolescent engagement in hygiene behaviours post COVID-19 pandemic onset in a high risk, sub-Saharan African setting, albeit with a small effect size. For future pandemics, it is important to understand predictors of engagement, particularly in the context of adversity, where adherence may be challenging. Limitations include a small sample size and potential measure shortcomings.

Assessment of the level of oral hygiene and the condition of the hard tissues of the teeth in ballet dancers of different age groups

The profession of ballet dancers is always associated with excessive physical exertion, which in turn leads to increased muscle tension in all parts of the body, including the muscles of the facial skeleton. This, in turn, can lead to injuries and increased abrasion of the hard tissues of the teeth and, as a result, to various occlusive disorders. Against the background of an excessively busy training schedule, a ballet dancer may lack time for oral hygiene. All of the above can affect the level of oral hygiene and the condition of the hard tissues of the teeth. The purpose of the study is to improve the efficiency and quality of dental care for ballet dancers of various age groups based on the identified features of oral hygiene and the condition of hard dental tissues and the need for dental treatment. Materials and methods: 75 ballet dancers were assessed for oral hygiene OHI-S and tooth erasability, determination of the area of occlusal contacts and registration of supracontacts. Results and conclusions: the age and work experience of a ballet dancer directly affects the level of oral hygiene and the condition of the hard tissues of the teeth. Ballet dancers have average satisfactory and high unsatisfactory indicators of the level of oral hygiene, as well as increased tooth abrasion and occlusive disorders of varying severity.

Study on the Correlation between Some Physical and Microbial Quality Characteristics of Peeled Sweet Orange (Citrus sinensis)

Background /Aim: The consumption of ready-to-eat fruits such as oranges has increased in recent times. This study assessed the correlation between some physical and microbial quality characteristics of peeled sweet orange (Citrus sinensis) sold in Yenagoa, the capital of Bayelsa State, Nigeria.&#x0D; Methodology: A total of thirty peeled oranges were purchased, three from each location. Standard microbiological methods were applied for the analysis.&#x0D; Results: Results showed that the in situ characteristics and microbiological load of peeled oranges sold in Yenagoa, Nigeria were in the ranges of 1.86 to 3.15 Log CFU/g (total fungi), 1.56 to 2.86 Log CFU/g (total heterotrophic bacteria), 3.14 to – 4.19 (pH), 1.84 to 3.03 ppt (salinity), 3.27 to 5.00 mS/cm (conductivity) and 2.56 to 4.10 ppt (total dissolved solid). There was statistical deviation (p&lt;0.05) for the in situ characteristics only. There was a positive significant association between the total dissolved solids and conductivity, and total heterotrophic bacteria and total fungi. Salinity negatively correlates with total heterotrophic bacteria and total fungi. The microbial isolates found in the samples include Staphylococcus aureus, Escherichia coli, Enterobacter, Bacillus, Proteus, and Micrococcus species, as well as Aspergillus, Penicillium, Mucor, Fusarium, Saccharomyces cerevisiae, and Trichoderma species.&#x0D; Conclusion: However, with improved handling and hygiene levels among orange vendors, the microbial load could be reduced. Furthermore, the study showed that similar factors affected the total dissolved solids, conductivity, total heterotrophic bacteria, and total fungi. While the negative correlations that exists between salinity and total heterotrophic bacteria and total fungi revealed that diverse factors affect their concentrations in the orange.

Oral Cavity Clinical Evaluation in Psychiatric Patients with Eating Disorders: A Case-Control Study

Bulimia nervosa and anorexia nervosa are not the only disorders the symptoms of which may be present in the oral cavity. The assessment of the clinical condition of patients with eating disorder symptoms was aimed at in this study. The study group consisted of 60 patients with diagnoses from categories F4.xx, F5x.x, and F6x.x ICD-10 (International Classification of Diseases, Tenth Revision). Patients were qualified for the study based on the answers provided in the symptom checklists "O". An adequate control group was selected. All patients underwent a dental examination, including the assessment of API (aproximal plaque index) and DMF (decayed missing filled index). Studies have shown that patients with eating disorder symptoms were more likely to have dental erosions (in total, 28.81% of cases). The correlation of erosion with the symptoms of eating disorders was demonstrated for several assessed symptoms present in the symptom checklists "O". Such correlations have not been demonstrated in terms of gingival recession presence. The level of oral hygiene in patients with eating disorders was assessed as sufficient or bad and indicates the need to initiate dental treatment in this group. It is important to correlate the treatment of the underlying mental disease with dental treatment and regular dental checkups.

The Importance of Conceptualising the Human-Centric Approach in Maintaining and Promoting Cybersecurity-Hygiene in Healthcare 4.0

The cyberspace depicts an increasing number of difficulties related to security, especially in healthcare. This is evident from how vulnerable critical infrastructures are to cyberattacks and are unprotected against cybercrime. Users, ideally, should maintain a good level of cyber hygiene, via regular software updates and the development of unique passwords, as an effective way to become resilient to cyberattacks. Cyber security breaches are a top priority, and most users are aware that their behaviours may put them at risk; however, they are not educated to follow best practices, such as protecting their passwords. Mass cyber education may serve as a means to offset poor cyber security behaviours; however, mandatory education becomes a questionable point if the content is not focused on human factors, using human-centric approaches and taking into account end users’ behaviours, which is currently the case. The nature of the present paper is largely exploratory, and the purpose is two-fold: To present and explore the cyber hygiene definition, context and habits of end users in order to strengthen our understanding of users. Our paper reports the best practices that should be used by healthcare organisations and healthcare professionals to maintain good cyber hygiene and how these can be applied via a healthcare use case scenario to increase awareness related to data privacy and cybersecurity. This is an issue of great importance and urgency considering the rapid increase of cyberattacks in healthcare organisations, mainly due to human errors. Further to that, based on human-centric approaches, our long-term vision and future work involves facilitating the development of efficient practices and education associated with cybersecurity hygiene via a flexible, adaptable and practical framework.

Improvement of self-performed oral hygiene among patients with braces and micro-implants: approbation of specifically designed plaque-controlled regime

Background. Braces and micro-implants may serve as retention points for the dental plaque under the condition of insufficient everyday oral care, thus compromising oral hygiene level of orthodontic patients.&#x0D; Objective. The assess changes of oral hygiene among orthodontic patients with braces and micro-implants during the use of adapted specifically-designed plaque-controlled regime of self-performed oral hygiene measures.&#x0D; Material and Methods. Study group was formed out of 30 patients aged 18 to 50 years, who were planned to undergo orthodontic treatment with brace system and micro-implant. During the first month of orthodontic treatment patients used a toothbrush with thin bristles, during the second month – V-toothbrush, and during the third month – a two-row and monobundle toothbrush. The interdental hygiene was provided by the size-adjusted toothbrushes. Clinical assessment was provided with the use of hygienic indices (O’Leary, Green-Vermillion and Turesky).&#x0D; Results. At the period of first month after orthodontic treatment initiation O’Leary index increased abruptly to 52.6±6.4%, which stands for unsatisfactory oral hygiene level. Values of Turesky and Green-Vermillion indices increased twofold after orthodontic appliance attachment, and after first month of treatment their values were 1.98±0.31, and 2.12±0.34 points, respectively; while after third month of treatment – 0.99±0.1 and 1.19±0.14, respectively.&#x0D; Conclusions. Oral hygiene conditions were deteriorated among all patients, compared to the pre-treatment situation, which was caused by orthodontic appliances fixation. Oral hygiene of the patients with fixed orthodontic appliances should include usage of two-row toothbrush, which most efficiently clean the plaque above and under the brace arch; and a mono-bundle toothbrush for additional cleaning around brace locks, in gingival area, and around micro-implants.

Evaluation of the Oral Health Conditions and Oral Health-Related Quality of Life in a Community-Dwellers Population Aged ≥ 45 Years in the Canton of Bern: A Preliminary Pilot Study.

To evaluate oral health conditions and oral health-related quality of life in community-dwellers aged ≥ 45 years in the Canton of Bern, Switzerland. One hundred subjects (63% males; mean age: 73 years), selected randomly using a cluster procedure within the Canton of Bern, underwent a clinical oral examination after completing questionnaires on socio-economic level, medical history, oral health behaviour, and Geriatric Oral Health Assessment Index (GOHAI). Descriptive analyses and multinomial regression models were applied to investigate the association between oral health diseases (dental caries and periodontitis) and specific participant characteristics. The mean number of decayed, missing, and filled teeth (DMFT) was 0.30, 4.20, and 8.75, respectively; the mean DMFT score = 13.35. Dental caries prevalence (ICDAS > 0) was 15% and periodontitis prevalence was 46%. Logistic regression models revealed that living in an urban area was associated with lower odds (OR 0.03, 95%CI 0.00-0.36) of having periodontal disease. Male gender was associated with lower odds for dental caries (OR 0.31, 95%CI 0.09-1.01) and total lack of professional tooth cleaning was associated with higher odds for dental caries (OR 41.99, 95%CI 0.01-0.38). Ordinal logistic regression revealed that both the presence of dental caries (RR 12.80, 95%CI 1.47-111.20) and periodontal disease (RR 6.91, 95%CI 1.16-84.00) were statistically significantly associated with rheumatoid arthritis. Within the study limitations, untreated dental caries and periodontal disease are prevalent in the Swiss population, despite the high level of self-performed oral hygiene and access to the dental care system.

Knowledge and Practice of Hand Hygiene Among Dental Undergraduates: A Cross-Sectional Study

Objectives: (1) To decipher the level of knowledge of hand hygiene among undergraduate dental students, (2) to assess the practice regarding hand hygiene among undergraduate dental students and (3) to identify the correlation between level of knowledge and practice of hand hygiene in clinical settings among undergraduate dental students. Materials and Methods: A cross-sectional study was conducted among undergraduate dental students from year 3 to year 5. Both validated self-administered questionnaires on hand hygiene knowledge by World Health Organization and questionnaire on hand hygiene practice were distributed to respective class representatives. Data on demographic characteristics were also collected. Prevalence was determined by descriptive statistics. Pearson’s correlation test was used to check the association between knowledge level and practice of hand hygiene. Results: Two hundred and fiftytwo subjects comprising of 87.7% females and 12.3% males were recruited. Response rate was 100%. Majority of respondents (74.6%) had good knowledge level of hand hygiene while 25.4% had moderate knowledge level. 100% of respondents had good practices of hand hygiene as they follow ≥50% in line with the recommended guideline. Level of knowledge were found to have weak correlation to practice of hand hygiene in clinical settings (r= -0.354, p&lt;0.001). Conclusion: Level of hand hygiene knowledge slightly influences the practice of hand hygiene in the form of negative correlation. Although respondents had good knowledge, there might be other external factors which influences the practice, such as lack of time and high patient workload. Further qualitative study should be conducted to elucidate other factors influencing the practice of hand hygiene among undergraduate dental students.

CLINICO-MYCOLOGICAL STUDY OF TINEA CAPITIS

Dermatophytes from the genera Trichophyton and Microsporum cause tinea capitis, a supercial fungal infection of the scalp and scalp hair. The fungi that cause the condition might change over time and space. Tinea capitis mostly affects youngsters, though it can sometimes affect adults. Children between the ages of 3 and 14 are the ones who are most likely to develop it . The lack of fatty acids in sebum, which have a fungi-static effect, has been linked to the increased prevalence in prepubertal children. With poor personal hygiene, congestion, and low socioeconomic level, transmission is exacerbated . The species may evolve over time in any location, particularly as new organisms are brought in via immigration. In order to identify the numerous etiological agents, different clinical kinds, research the epidemiological features, and establish the clinico-mycological association of tinea capitis, a study was carried out in our hospital .

Safety Evaluation of Rock Hyrax (Procavia capensis) Hyraceum: Oral Toxicity Study in Rats

Urine from domestic animals has traditionally been used to treat multiple human diseases. Rock hyrax hyraceum (RHH) is a dark brown resin-like substance made up of accumulated feces and urine of rock hyraxes, used in traditional African medicine to treat snake and scorpion bites, as well as colic, hysteria, epilepsy, and Parkinson’s disease. As there is no scientific backing for the utilization of hyrax hyraceum, there is an urgent need to establish its safety as a medicine. Furthermore, toxicity evaluation facilitates the identification of factors for clinical surveillance of the potential side effects, as well as the estimation of a preliminary hygienic dose level and dosing frequency range for human clinical trials. The safety of RHH was assessed by administering 2.5 and 5 gm/kg doses of hyraceum crystals dissolved in de-ionized water and administered to rats orally. We evaluated the acute toxicity profile, as well as the effect of RHH on liver and kidney function and histopathological investigations. The results of this investigation showed that consuming RHH does not have any hazardous effects on liver and kidney function and histopathological investigations. Drinking RHH did not cause toxicity. These findings are consistent with those of previous studies of drinking cows and camel urine. We encourage more research on hyraceum composition in relation to rock hyrax habitat areas and eating patterns, as we believe it will help us understand why people practice drinking hyraceum as a medicine.

Does using mobile applications and social media-based interventions induce beneficial behavioral changes among orthodontic patients?

Systematic review and meta-analysis of randomized controlled trials (RCTs) and controlled clinical trials (CCTs). The protocol of the study was registered on the International Prospective Register of Systematic Reviews (PROSPERO: CRD42019157298). Seven electronic databases (MEDLINE, Web of Science Core Collection, Unpublished Clinical Trials accessed through clinicaltrials.gov, Embase, LILACS, ProQuest Database, The Cochrane Library) were searched. Additionally, the reference lists of the included studies were hand searched. Clinical trials (RCT and CCT) that assessed the impact of the interventional use of mobile applications and social media among orthodontic patients were included. The review question was defined in PICO format as follows: population (P)= patients (no age restriction) undergoing orthodontic treatment using fixed, removable, or functional appliances, or patients in the retention phase that are wearing fixed or removable retainers; intervention (I)= mobile applications and social media-based interventions; comparison (C)= control group that did not receive any adjunctive intervention; outcome (O)= behavior changes in orthodontic patients after receipt of the intervention. Two authors independently conducted literature search from inception up to March 2021. Social media-based interventions and mobile applications (or bespoke) were used in the form of reminders (WhatsApp reminders) and provision of information including YouTube videos and Instagram posts. Primary outcomes included adherence to wearing appliances or adjuncts, oral hygiene levels, oral health-related behaviors, periodontal outcomes, appointment attendance, knowledge, and related iatrogenic effects. Treatment-related experiences and patient-reported outcomes were assessed as secondary outcomes. 16 studies (14 RCTs and 2 CCTs) were included in the qualitative synthesis, of which only 7 studies were included in the quantitative synthesis (meta-analysis). Results from meta-analyses showed that the intervention was favored in relation to gingival index (GI) (number of studies = 4, standardized mean difference [SMD] = -0.81, 95% confidence interval [CI] = -1.35 to -0.28, P = 0.00, certainty of evidence = very low), plaque index (PI) (number of studies = 7, SMD = -0.91 [95% CI, -1.64 to -0.19], P = 0.01, certainty of evidence = very low), and bleeding index (BI) (number of studies = 4, SMD = -0.22 [95% CI, -0.50 to 0.05], P = 0.11, certainty of evidence = high). Sensitivity analysis was performed (including additional 3 studies for GI and 5 studies for PI), which also favored the intervention in relation to GI (number of studies = 7, SMD = -0.60 [95% CI, -1.01 to -0.18], P = 0.00, certainty of evidence = very low), and PI (number of studies = 12, SMD = -0.67 [95% CI, -1.14 to -0.19], P = 0.01, certainty of evidence = very low). Limited evidence supports beneficial behavior change among orthodontic patients when using mobile applications or social media-based interventions.

Pelayanan Screening Kesehatan Anak Usia Sekolah Di SDK Wehor Wilayah Puskesmas Haliwen Kecamatan Kakuluk Mesak

Schools are one of the targets of the Community-Based Total Sanitation program in the form of an area that is a strategy for improving PHBS. School-age children (6-10 years) are the most vulnerable to disease transmission. Schools can also be a place of learning and a threat of disease transmission if not appropriately managed. On the other hand, the number of school children who reach 30% of the total population of Indonesia is the potential as an "Agent of Change" to promote health in schools, families, and communities. Service activities were carried out at SDK Wehor, Kabuna, Kakuluk Mesak District, Belu Regency, Province of East Nusa Tenggara. Service activities for class I (one) students. Health screening was carried out by counseling and demonstration methods using a phantom/mannequin model of children's teeth, toothbrush, microtoice, scales, tuning fork (fork), and Snellen Chart. The students were very enthusiastic about participating in health counseling and screening activities from the beginning to the end of the event. The level of dental and oral hygiene of school-age children (Wehor SDK) 95% of school-age children, especially in Wehor SDK, have nutritional status with obesity category as much as 35.3% eye and ear health of all normal students.

Evaluation of Oral Hygiene and Periodontal Indices of 6–14-Year-Old Children with Insulin-Dependent Diabetes Mellitus

The purpose of the study was to evaluate oral hygiene and periodontal indices in children with type 1 diabetes mellitus. Materials and methods. 258 children aged 6-14 years were examined, including 129 children with type 1 diabetes mellitus and 129 children without concomitant somatic diseases. All patients were divided into four subgroups according to the presence of gingivitis. We determined the oral hygiene index-simplified (according to Green, Vermillion, 1964), the papillary-marginal-alveolar index in Parma modification (1960), the gingival index according to Loe, Sillness (1967). The t-test for paired samples was used to compare values. The difference was considered statistically significant at p&lt;0.05. Results and discussion. The worst level of oral hygiene was in group of children with type 1 diabetes mellitus and chronic catarrhal gingivitis because gum bleeding and pain in gums in these children did not allow them to make full efforts and carry out oral hygiene well. Our research showed a statistically significant difference between the patients with type 1 diabetes mellitus and control group in accordance with periodontal indices. Children with diabetes mellitus had the highest values of periodontal indices. The inflammatory processes in the tissues of periodontium in patients with type 1 diabetes mellitus are expanded, so it is very important to recognize them and diagnose them as early as possible. Periodontal indices in patients of the youngest age subgroup, namely, both the group of patients with diabetes mellitus and the group of children without somatic pathologies were the lowest. The totality of data on periodontal indices in children with chronic catarrhal gingivitis and type 1 diabetes mellitus indicated an average degree of severity of gingivitis, namely, the papillary-marginal-alveolar index was 42.77 ± 1.31%, the gingival index was 1.81 ± 0.05 points. Protective mechanisms in young patients with type 1 diabetes mellitus are changed. Children with this endocrine illness suffer from swelling of the gums and have extreme gum bleeding along with the development of the main endocrinological disease compared to healthy patients of the same age. According to the results we obtained, we believe that screenings of the oral cavity and preventive programs should emphasize the importance of early diagnosis of gingivitis and periodontitis even during the milk and mixed bite period, particularly in children with type 1 diabetes mellitus. Conclusion. Children with type 1 diabetes mellitus had a worse state of oral hygiene than healthy children. Children with diabetes mellitus had gum bleeding both during the period of temporary bite, and during the period of mixed bite

Impact of River Water Quality on Public Health in Perspective of Asian Rivers: A Case Study of Buriganga River, Bangladesh

Water pollution is one of the current global problems. So many countries are suffering from this problem specifically most South Asian and Southeast Asian countries, and Bangladesh is one of those countries that are suffering from water pollution. Furthermore, the city of Bangladesh, Dhaka is one of the most densely populated cities in the world and overpopulation is showing a negative impact on the water quality now. Most of the rivers are very polluted around Dhaka city because of anthropogenic causes. This study focused on Buriganga river pollution and its impact on public health. This study intended to find out the major cause of Buriganga river pollution and the health status of the community living beside the Buriganga river. Also the study identified all the common diseases which people are suffering from around the Buriganga river area. Then the study compared the results with other southeast Asian countries so that it can make the relationship and can make it easier to understand the current situation of water pollution on public health in East Asia and Southeast Asia regions. During the research work, it was noticed that the Buriganga river is very polluted due to human activities. The transportation system, fishing, and waste canals from industries become the primary reasons behind Buriganga’s current condition. Also irresponsibility of both the environmental department and civil society is the major factor in Buriganga river pollution. The hygienic level was also not in a good condition because so many wastes like plastic materials and other daily use materials were thrown out into the river. That’s why public health conditions around the Buriganga river become vulnerable nowadays. So policies have to be implemented from the right perspective and the institutions have to be strong enough to handle all the issues regarding the Buriganga River.

With Phenotypic Signs of Connective Tissue Dysplasia: Cross-Sectional Clinical Study

Background. The dental health is an integral part of a person's well-being. Students of higher educational institutions comprise a health risk group, since they experience extensive physiological changes and personal socialization. The impact of connective tissue dysplasia on dental health is a relevant research task.Objective. To analyze the correlation between dental pathology and phenotypic signs of connective tissue dysplasia in first-year students.Methods. A cross-sectional clinical study of the dental health and phenotypic signs of connective tissue dysplasia was conducted as part of routine dental examination of 263 first-year students of KubSMU, aged 18–23. All participants were divided into 2 groups: group 1 – participants with 0-2 signs of connective tissue dysplasia (n = 108); group 2 – participants with 3 or more signs of dysplasia (n = 155). Statistical analysis of the results was carried out using Microsoft Excel 2010 and Statistica 6.0.Results. Unsatisfactory and poor oral hygiene levels in the group of participants with connective tissue dysplasia outnumber these levels in the control group by 30% and 22%, with very poor level in the second group 2.3 times higher (p ≤ 0.05). The incidence of noncarious tooth pathology in individuals with dysplasia is 26% higher than in the control group. The caries intensity index in group 2 is almost 20% bigger than in the control group. As expected, the group of participants with no signs of dysplasia revealed better periodontal health, namely 51.85% versus 45.81% (p ≤ 0.05). In terms of mucosal pathology, a statistical significant difference between groups 1 and 2 was noted for traumatic injuries (16.35% and 19.35%, respectively). Dentofacial abnormalities were observed more often in individuals with 3 or more phenotypic signs of connective tissue dysplasia.Conclusion. Higher morbidity rate of caries and noncarious pathology in the group of first-year students with 3 or more phenotypic signs of connective tissue dysplasia, compared to the group with 0–2 phenotypic manifestations of dysplasia, indicated the need to create a database of the dentofacial profiles of students, develop an algorithm for regular medical check-up of students, as well as provide differentiated preventive and therapeutic measures for students with dysplasia.

КЛИНИКО-РЕНТГЕНОЛОГИЧЕСКИЙ АНАЛИЗ СТРУКТУР ПАРОДОНТА ПРИ АНАТОМО-ФУНКЦИОНАЛЬНЫХ НАРУШЕНИЯХ МУКОГИНГИВАЛЬНОГО КОМПЛЕКСА

Subject. Anatomical and functional disorders of the mucogingival complex.&#x0D; Objectives. To evaluate microcirculatory, clinical and radiological changes in periodontal tissues in various variants of mucogingival complex disorders.&#x0D; Methodology. The study was conducted at the Department of Therapeutic Dentistry of ASMU. In the course of the study, 80 patients (49 women, 31 men) aged 18 to 35 years were examined with a ratio of dentition close to orthognathic bite in the presence of maximum occlusion. Three groups were formed depending on the anatomical and functional state of the mucogingival complex. In the clinical part of the study, an objective assessment of the condition of periodontal tissues was carried out on the basis of a dental examination with a comprehensive analysis of the periodontal status. The X-ray examination included the analysis and description of cone-beam computed tomograms for patients of clinical groups. To assess microcirculation in periodontal tissues, the method of ultrasonic Dopplerography with functional probe breakdown was used.&#x0D; Results. In the studied groups, the level of oral hygiene was characterized as good, and the indicators of hygiene indices did not differ significantly, periodontal indices indicated the absence or minimal degree of inflammation in periodontal tissues. Carrying out a functional tension test made it possible to divide patients into subgroups according to the type of reaction: normal, compensated, subcompensated, decompensated. According to the results of the study of CBCT in the comparison group, pathological changes in the bone tissue of the alveolar process of the studied areas were not recorded, in patients of the first clinical group, in most cases (80.2%), pathological changes in the bone tissue of the alveolar process were not observed, in the rest (19.8%), a low level of alveolar bone was noted. In patients of the second clinical group, the phenomena of osteoporosis and an increase in the distance from the dental enamel-cement border to the edge of the outer cortical plate were recorded.&#x0D; Conclusions. X-ray changes in bone tissue most often corresponded to the already existing clinical symptoms of periodontal tissue damage against the background of mucogingival pathology. The predictors of prenosological diagnosis in anatomical and functional disorders of the mucogingival complex were changes in microcirculation indicators.

Mother-to-daughter transmission of hygienic anti-parasite behaviour in mandrills.

Social animals are particularly exposed to infectious diseases. Pathogen-driven selection pressures have thus favoured the evolution of behavioural adaptations to decrease transmission risk such as the avoidance of contagious individuals. Yet, such strategies deprive individuals of valuable social interactions, generating a cost-benefit trade-off between pathogen avoidance and social opportunities. Recent studies revealed that hosts differ in these behavioural defences, but the determinants driving such inter-individual variation remain understudied. Using 6 years of behavioural and parasite data on a large natural population of mandrills (Mandrillus sphinx), we showed that, when parasite prevalence was high in the population, females avoided grooming their conspecifics' peri-anal region (PAR), where contagious gastro-intestinal parasites accumulate. Females varied, however, in their propensity to avoid this risky body region: across years, some females consistently avoided grooming it, while others did not. Interestingly, hygienic females (i.e. those avoiding the PAR) were less parasitized than non-hygienic females. Finally, age, dominance rank and grooming frequency did not influence a female's hygiene, but both mother-daughter and maternal half-sisters exhibited similar hygienic levels, whereas paternal half-sisters and non-kin dyads did not, suggesting a social transmission of this behaviour. Our study emphasizes that the social inheritance of hygiene may structure behavioural resistance to pathogens in host populations with potential consequences on the dynamics of infectious diseases.

“Dental Health” preventive program as a stage of rehabilitating children with cognitive developmental disabilities

Relevance. One of the paramount directions of preventive dentistry is the development of the author's methods of organization and implementation of dental diseases prevention programs in children with cognitive developmental disabilities, allowing for prevention customization, taking into account the features of child development with disabilities, as well as the combination of many objective factors. The study aimed to increase the efficiency of mentally-retarded children's rehabilitation by improving the dental disease prevention program.Materials and methods. The study involved 140 children diagnosed with moderate mental retardation and comparatively analyzed two methods over three years. Group 1 included 71 subjects aged 8-11 years trained according to "Dental Health", the author's dental and hygiene education program, developed and adjusted to the psychophysical needs of the child development. Group 2 consisted of 69 subjects, trained according to the dental and hygiene education program provided only by the teachers during classes on household chores. We evaluated the effectiveness of the "Dental Health" prevention program introduced into the specialized educational process by the following indices DMFT, simplified oral hygiene index (OHI-S); PMA index modified by Parma assessed the condition of the gums. Statistical data were processed using the IBM SPSS Statistics 18.0 application sof tware package.Results. The effectiveness analysis of the author's program for children with moderate mental retardation revealed that the level of oral hygiene in the children increased from "poor" to "good" (2.1 ± 0.3 points to good 0.2 ± 0.1 points); gingival inflammation decreased from 24.6 ± 0.5% to 14.4 ± 0.2%. Classes on dental education and hygiene training helped children with cognitive developmental disabilities to orient better in self, time and place; helped to improve memory, increase vocabulary, form new knowledge and skills, and gradually form effective communication based on the child's intellectual deficiency severity.Conclusions. The developed educational program "Dental Health" for dental diseases primary prevention in children with cognitive developmental disabilities allowed the formation of stable oral care skills, proved by a good score of oral hygiene indices.
