Ecological Study on the Oral Health of Romanian Intellectually Challenged Athletes

This study aimed to give an image of the oral health status and treatment needs of intellectually challenged athletes taking part in Special Olympics—Special Smiles (SO-SS) events organized in Romania during 2011–2019 and to find potential associations with socio-economic factors. An observational ecological retrospective study was conducted, and 1860 oral examinations were performed on participants aged 8 to 30 years in nine SS-SO events. Oral examination was performed under field conditions. Percentage of caries-free subjects, mean DMF-T index and its components (D = decayed; M = missing; F = filled; T = teeth), restoration index RI = [F/(F + D) × 100]%, and Plaque Index were calculated for each of the nine groups. Caries-free subjects ranged between 5.90% and 21.70%. DMF-T ranged from 4.27 to 7.71. Higher values for “F” component (range 0.66–1.69) and RI (range 13.02–27.74%) were found in events held in cities from regions with higher reported Gross Domestic Product. Sealants were present in 0 to 8.4% of the subjects. In areas with lower numbers of inhabitants per dentist, more sealants were found (p < 0.001). Romanian SO athletes exhibited relatively poor oral health, limited access to dental treatment, and low level of prevention. Targeted prevention and treatment programs adjusted to specific conditions in each geo-economic region are needed.

Low Levels of Tumor Necrosis Factor-α will Prevent Periodontitis Exacerbation in Type 2 Diabetes Mellitus

Objectives Diabetes mellitus (DM) is a major risk factor for periodontitis. Susceptibility to periodontitis increases approximately three times in people with DM. There is a clear relationship between the degree of hyperglycemia and the severity of periodontitis. This study aimed to analyze the reduction of tumor necrosis factor-α (TNF-α) in diabetics who came for periodontitis examination to prevent exacerbations. Materials and Methods This was an analytic observational study using a cross-sectional approach at health centers in Surabaya, Indonesia. Measurement of periodontal status used the community periodontal index of treatment needs by measuring bleeding at probing and pocket depth. TNF-α was measured using enzyme-linked immunosorbent assay, and behavior and lifestyle using a questionnaire. Statistical Analysis The Kolmogorov–Smirnov test was performed to identify data normality (p < 0.05). A nonparametric test was used to measure the degree of association between different characteristics and the incidence of periodontitis in type 2 DM patients with and without periodontitis. Spearman's test was done to examine the correlation between TNF-α level and severity of periodontitis in diabetics. The significant level was at p <0.05. Results There was a correlation between age, predisposing factors, reinforcing factors, drug consumption, and TNF-α levels in patients with type 2 DM and the incidence of periodontitis. Conclusions Poor glycemic control can induce oxidative stress on the gingiva, thereby aggravating damage to periodontal tissue. An important factor in preventing periodontitis for type 2 DM patients is controlling blood sugar levels through regular consumption of drugs and regular maintenance of oral cavity health. Knowledge is a predisposing factor that affects adherence of people with type 2 DM to consuming drugs regularly, which can be strengthened by family support. These will ultimately play a role in reducing TNF-α levels.

The Impact of Extended-Time Proppant Conductivity Impairment on the Ultimate Recovery from Unconventional Horizontal Well Completions

The stimulation design of hydraulically fractured wells has always pitted the engineer's capability to maximize the fracture extent (or fracture half-length within the formation) versus the conductivity of the fracture pack generated by the deposited proppant material. In essence, the area of productive reservoir rock contacted by the hydraulic fracture treatment needs to be appropriately engineered to remain connected to the wellbore over the life of the well to maximize reservoir recovery. The completion design of multi-stage hydraulically fractured horizontal wells has been driven by their application to unconventional oil and gas reservoirs. This has primarily occurred in North America where most of the wells drilled and completed were operated by small, private, or upstream-only independent public companies. Metrics used to evaluate performance and completion design changes were short-term in nature and typically focused on parameters such as peak-month production, 90- or 180-day cumulative production; or at longest, the first year or two of cumulative production. Capital efficiency, and capital return or well payout were drivers of value creation in an environment where the well inventory was viewed as extensive if not unlimited and the quick recycling of invested capital created the illusion of value creation. Short-term performance metrics give credence to fracture designs that value most the early-time production that is dominated by rate acceleration. The work presented in this paper shows a comparison of fracture designs in deep unconventional formations looking to minimize cost by pumping all sand proppants versus a focus on ultimate recovery from the reservoir with designs that are more applicable to the stress regime. The work shows the importance of maintaining the wellbore connectivity to the reservoir by designing fracture treatments using proppant conductivity decline data measured over an extended-time period of months or years to maximize ultimate recovery from the reservoir. This approach will be critical to those E&P companies who view their well inventory or resource base as finite and consequently place a priority on maximizing recovery from the reservoir.

Orthodontic treatment needs: parents and child perception

Background: Malocclusion is one of the most common oral cavity malformations. It has a variety of effects on dental health, function, aesthetics, and psychosocial condition. The suggested treatment for such a condition is orthodontic treatment. This study aims to assess the perceptions of orthodontic treatment needs of parents and their children with relation to their perception in Riyadh, Saudi Arabia.Methods: This is a cross-sectional study that was conducted to study the perception of children and their parents about the need for orthodontic treatment. The data were collected at the pediatric clinics of Riyadh Elm university in Riyadh, Saudi Arabia, and included 379 parents and their school children aged 4-12 years. An interviewed questionnaire was used to collect the data from the children and their parents separately.Results: The study found that the perception towards the need for orthodontic treatment of children and their parents was 44.6%, and 34.8% respectively. Also, a statistically significant difference was shown between the perception of children and their parents (p>0.05). The main factors affecting the perception was age, as the desire to have orthodontic treatment increased among children above age of 10 years. Other factors including satisfaction about chewing, teeth appearance, and social media altered the perception for orthodontic treatment need.Conclusions: These findings could be essential for orthodontic treatment planning and increasing patient compliance. The difference between children and parents’ perceptions can affect drive toward initial orthodontic visit.

Social Media Discussions Predict Mental Health Consultations on College Campuses

The mental health of college students is a growing concern, and gauging the mental health needs of college students is difficult to assess in real-time and in scale. To address this gap, researchers and practitioners have encouraged the use of passive technologies. Social media is one such "passive sensor" that has shown potential as a viable "passive sensor" of mental health. However, the construct validity and in-practice reliability of computational assessments of mental health constructs with social media data remain largely unexplored. Towards this goal, we study how assessing the mental health of college students using social media data correspond with ground-truth data of on-campus mental health consultations. For a large U.S. public university, we obtained ground-truth data of on-campus mental health consultations between 2011–2016, and collected 66,000 posts from the university’s Reddit community. We adopted machine learning and natural language methodologies to measure symptomatic mental health expressions of depression, anxiety, stress, suicidal ideation, and psychosis on the social media data. Seasonal auto-regressive integrated moving average (SARIMA) models of forecasting on-campus mental health consultations showed that incorporating social media data led to predictions with r = 0.86 and SMAPE = 13.30, outperforming models without social media data by 41%. Our language analyses revealed that social media discussions during high mental health consultations months consisted of discussions on academics and career, whereas months of low mental health consultations saliently show expressions of positive affect, collective identity, and socialization. This study reveals that social media data can improve our understanding of college students’ mental health, particularly their mental health treatment needs.

Prevalence and pattern of acute and chronic multimorbidity across all body systems and age groups in primary health care

Multimorbidity is more than just the addition of individual illnesses, and its diagnosis and treatment poses special problems. General practitioners play an important role in looking after multimorbid patients. The aim of this study is to assess the prevalence and pattern of acute and chronic multimorbidity in primary care patients, regardless of body system and age group. A convenience sample of 2099 patients treated by 40 general practitioners was assessed using the Burvill scale. This measure of multimorbidity differentiates according to organ system and covers both acute and chronic illnesses. It also allows severity ratings to be assessed for both acute and chronic conditions, and thus patients’ actual need for general practice care. Patients reported an average of 3.5 (SD = 2.0) acute and/or chronically affected body systems. Overall, 12.7% of patients reported only one health problem, 83.0% at least two, 65.8% at least three, 46.1% at least four, and 29.7% five or more. The most frequent problems were musculoskeletal (62.5%) and psychological (56.6%). Some morbidities were interrelated, while others co-occurred despite being medically independent. In primary care, multimorbidity is the rule rather than the exception. Acute and chronic morbidity both contribute to the burden of illness. Body systems reflect treatment needs. Instead of specialist treatment for individual illnesses, an integrative treatment approach is needed. This is the specialty of general practitioners.

Biomarkers of Length of Stay On An Inpatient Eating Disorder Unit For Treatment of Anorexia Nervosa in Females

Background. Length of stay on an inpatient unit for treatment of anorexia nervosa (AN) is widely variable. Although previous research has used anthropometric and clinical variables and duration of illness to predict length of stay, there has been limited investigation of the predictive ability of biomarkers. Biomarkers, including those collected through a comprehensive metabolic panel (CMP) and appetite hormones, such as ghrelin and leptin, are impacted by disease presence and may play an etiological role in AN. Methods. Using a series of regression models, we retrospectively evaluated the associations of these putative biomarkers at admission with length of inpatient stay in 59 females receiving treatment on an inpatient eating disorder unit for anorexia nervosa. Results. Both lower levels of magnesium and higher active ghrelin levels at inpatient admission predicted length of stay. Conclusions. This research provides further evidence supporting both biological and psychological components of AN, identifying potential biomarkers that could aid in prospective prediction of treatment needs. Ghrelin monitoring throughout inpatient stays may aid clinicians in better predicting physical recovery and renourishment from AN and prepare for stepdown from an inpatient setting. Further research is necessary to replicate and extend these findings across treatment settings.

Risk Indicators and Treatment Needs of Children 2–5 Years of Age Receiving Dental Treatment under General Anesthesia in Saskatchewan

Background: When compared to national averages in Canada, Saskatchewan has one of the highest rates of dental treatment under general anesthesia (GA) and average costs per child. Thus, the purpose of this cross-sectional study is to explore the risk indicators and treatment needs of children receiving dental treatment under GA in Saskatchewan. Methods: In this cross-sectional study, we recruited caregivers of children between 24 and 71 months of age in Saskatoon, Canada. Caregivers completed a 40-item questionnaire, which was supplemented with clinical data and then subject to statistical analysis (independent t-tests and one-way ANOVA). Results: A total of 90 caregiver/child dyads were enrolled with the mean age for children being 49.5 ± 12.3 months. The mean age of a child’s first dental visit was 34.7 ± 15.3 months with only 37.9% of children having a dental home. The mean deft index was 11.7 ± 3.4, with an average of 10.9 ± 3.5 teeth receiving treatment. Additionally, location of primary residence (p = 0.03), family income (p = 0.04), family size (p = 0.01), parental education (p = 0.03), dental home (p = 0.04), and body mass index (p = 0.04) had a statistically significant association with a higher mean deft. Conclusions: Our cross-sectional study confirms that children who require dental treatment under GA have a high burden of disease. While individual risk indicators such as diet and oral hygiene play a role in the progression of early childhood caries (ECC), we also demonstrate that children who do not have access to early preventive visits or a dental home are at a higher risk. In addition to improving motivation for oral hygiene at home and nutritional education, improving access to oral health care should be addressed in strategies to reduce ECC.

Green Production of Zero-Valent Iron (ZVI) Using Tea-Leaf Extracts for Fenton Degradation of Mixed Rhodamine B and Methyl Orange Dyes

The danger from the content of dyes produced by textile-industry waste can cause environmental degradation when not appropriately treated. However, existing waste-treatment methods have not been effective in degrading dyes in textile waste. Zero-valent iron (ZVI), which has been widely used for wastewater treatment, needs to be developed to acquire effective green production. Tea (Camellia sinensis) leaves contain many polyphenolic compounds used as natural reducing agents. Therefore, this study aims to synthesize ZVI using biological reducing agents from tea-leaf extract and apply the Fenton method to degrade the color mixture of rhodamine B and methyl orange. The results show that the highest polyphenols were obtained from tea extract by heating to 90 °C for 80 min. Furthermore, PSA results show that ZVI had a homogeneous size of iron and tea extract at a volume ratio of 1:3. The SEM-EDS results show that all samples had agglomerated particles. The ZVI 1:1 showed the best results, with a 100% decrease in the color intensity of the dye mixture for 60 min of reaction and a degradation percentage of 100% and 66.47% for rhodamine B and methyl orange from LC-MS analysis, respectively. Finally, the decrease in COD value by ZVI was 92.11%, higher than the 47.36% decrease obtained using Fe(II).

Prevalence of partial edentulism among the patients visiting a Tertiary Health Care Center in the Western Region, Nepal

Introduction: Tooth loss causes impairment, functional limitation, physical, psychological, and social disability. Hence, the study of pattern of tooth loss can provide a rough information about the frequency, cause and magnitude of oral problems, its sequelae that eventually can act as mirror image of prosthodontic treatment needs. Objectives: To assess the prevalence of partial edentulism and its etiology, to determine its association with sociodemographic parameters, and to find out the motivational factor/s for replacement in willing patients. Methods: Total 417 patients with partial edentulism were examined intraorally on the basis of Kennedy’s classification with Applegate’s modification. The descriptive analysis was done using frequency distribution. Pearson Chi-square analysis test was used to determine the association between demographic variables and type of tooth loss where p-value ≤0.05 was considered statistically significant. Results: Partial edentulism was more prevalent in mandibular arch (41.7%) followed by both arches (30.9%). Kennedy’s Class III was the commonest and Kennedy’s class III modification 1 was second most common type of partial edentulism. Age and educational status had statistically significant association while gender had no association with various classes of partial edentulism. Dental caries (62.8%) followed by periodontitis (25.9%) were the major causes of tooth loss. Functional demand (46.8%) was the key motivational factor for the replacement among those who were willing (78.4%). Conclusions: This study can help in assessing the epidemiological features of partial edentulism of one community in a more classified form and can help gather information necessary to assess the treatment needs.
