MATERIALS AND METHODS: Self-administered questionnaires were distributed to 400 subjects. The questionnaire comprised three parts; the first part addressed the demographic variables. The second part queried about dental prosthesis, orthognathic or plastic surgery, and/or ongoing or previous orthodontic treatment. The third part included the Arabic version of the-8-item Orofacial Esthetic Scale (OES-Ar) whose responses were scored in the 5-point Likert scale. These scores were compared by different grouping factors (age, gender, marital status, and education) using non-parametric Mann-Whitney U and Kruskal Willis tests with 95% confidence interval (α > 0.05).
RESULTS: A total of 268 questionnaires were eligible for analysis, representing 67% response rate. The satisfaction with facial profile appearance was the highest (4.0±1.1) followed by facial appearance (3.9±1.1), while the color of teeth was the least satisfying item (3.1±1.3). No significant differences were found between age groups for the mean summary score as well as for each item independently. No significant difference was found between both sexes except for the last item "overall impression". Married subjects rated one item (alignment of teeth) better than their counterparts. Positive perception of orofacial appearance increased significantly with the increase of education level, the perception of the oral health status, and the perception of the general health status.
CONCLUSION: Good oral health and/or high education level are significant determinants of more positive perception of orofacial esthetic appearance. Patients with these characteristics might be more concerned about their orofacial appearance, and this should be taken into consideration before planning any esthetic restorative dental treatment.
METHODS: We source daily death registry data for 4100 municipalities in Italy's north and match them to Census data. We augment the dataset with municipality-level data on a host of co-factors of COVID-19 mortality, which we exploit in a differences-in-differences regression model to analyze COVID-19-induced mortality.
RESULTS: We find that COVID-19 killed more than 0.15% of the local population during the first wave of the epidemic. We also show that official statistics vastly underreport this death toll, by about 60%. Next, we uncover the dramatic effects of the epidemic on nursing home residents in the outbreak epicenter: in municipalities with a high share of the elderly living in nursing homes, COVID-19 mortality was about twice as high as in those with no nursing home intown.
CONCLUSIONS: A pro-active approach in managing the epidemic is key to reduce COVID-19 mortality. Authorities should ramp-up testing capacity and increase contact-tracing abilities. Adequate protective equipment should be provided to nursing home residents and staff.
METHODS: A total of 120 healthy volunteers were enrolled (55 adult males, 32 adult females, and 33 children). The volunteers were interviewed for any bleeding history or drug intake which affects coagulation. Kaolin-activated TEG was performed on citrated whole blood, and parameters including R-time, K-time, angle, MA, LY30, and CI were analyzed.
RESULTS: Derived reference range for total volunteers irrespective of age and sex were as follows: R-time: 3.8-10.6, K-time: 1.2-3.1, angle: 44.9-72.0, MA: 41.2-64.5, LY30: 0-9.9, and CI: -3.7 to 3.4. Statistically significant difference was observed in different age and sex groups for R-time, K-time, and angle. About 40% of the volunteers had at least one abnormal parameter according to the manufacturer's reference range which decreased to 12.5% when the derived reference ranges were considered.
CONCLUSION: Gender- and age-related variances were observed in reference ranges of our population and which was also differed from the other ethnic population. Many of our healthy volunteers were categorized as coagulopathic when manufacturer's reference range was considered. So, it is important to derive the reference range of the target population before using the TEG into clinical practice.
METHODS: This was an observational cohort on incident end-stage kidney disease (ESKD) patients from January 1, 2007 to December 31, 2008. The primary outcome was all-cause mortality. Patients contributed person-time from the date of ESKD diagnosis until death, transplant or end of study on December 31, 2014, whichever occurred first. An extended Cox regression model with time-varying exposure to dialysis was used to account for immortal time bias.
RESULTS: Of 3990 incident ESKD patients included, 70.2% patients initiated dialysis; 78.8% with haemodialysis (HD) while the remaining 21.2% with peritoneal dialysis (PD). Dialysis reduced hazard of death in both elderly and non-elderly patients even after controlling for comorbidities (hazard ratio [HR] 0.58, 95% confidence interval [CI] 0.50, 0.68 and HR 0.76, 95% CI 0.69, 0.85, respectively). HD was protective in both the elderly and non-elderly (HR 0.53, 95% CI 0.45, 0.63 and HR 0.71, 95% CI 0.64, 0.80, respectively). PD significantly reduced risk of death compared to no dialysis in the elderly but not in the non-elderly.
CONCLUSION: Dialysis improved survival in all incident ESKD patients. The findings suggested a larger protection offered by HD. Although improvement in survival from initiating dialysis was large, its true benefit should take overall quality of life into account. SUMMARY AT A GLANCE This observational study showed that initiation of dialysis improves the survival of end-stage kidney disease (ESKD) patients of all age groups, but the quality of life is an important aspect that has not been explored.
