Aim: The main aim of this study was to Evaluate of Decayed, Missing and Filled Teeth (DMFT) Index in 12 Year Old Students of Tehran City, and to identify related factors that affect dental caries within this group. Methods: A cross-sectional survey was conducted among students of 12 years old in Tehran, Iran. Dental caries status was assessed in terms of decayed teeth (DT), filled teeth (FT) and decayed, missing and filled teeth (DMFT). “Data were analysed using SPSS version 22; a multivariate regression analysis was used to determine statistically significant associations between DMFT and other variables (p < 0.05). Results: A total of 416 respondents participated in the study. The mean age of the students was10.94 (SD=0.628) years, and the mean DMFT was 1.03 (SD=1.41). So that, in this study DT (0.53 ± 0.95) had the highest and MT (0.14 ± 0.47) had the lowest mean. A multivariate regression analysis model results showed a significant relation between high DMFT scores and such variables as increasing age, lower levels of mother's education, higher family income, lower frequency of tooth brushing and dental flossing, having a history of no visits to the dentist (P<0.05). Conclusion: The current study shows that Iranian female students have a poor oral health behavior, as very few subjects use dental floss on a regular basis. Although there appeared to be a significant relationship between caries scores and demographic factors such as age and socio-behavioral variables include  family income, the level of mothers' education, the frequency of dental brushing and flossing, and both the frequency and type of visit to a dentist.

The complaint of fatigue is common in community, primary care, and psychiatric settings. Fatigue is often associated with depression and psychosocial stress. This report investigated the role of alexithymia and depression in fatigue as reported in a sample of 151 psychiatric outpatients (75 men and 76 women) who completed all scales. The mean age of the sample was 45.5 yr. ( SD = 12.5), and mean education was 16.2 yr. ( SD = 2.4). Fatigue was inversely correlated with education (–.16) and positively correlated with depression (.44), anxiety (.30), and alexithymia (.35). However, in a multivariate regression analysis, only depression and alexithymia remained significant ( p ≤ .01).

Background Arterial stiffness assessed by carotid-femoral pulse wave velocity (PWV) is an independent predictor of cardiovascular morbidity and mortality. We aimed to investigate how various measures of obesity affect arterial stiffness. Methods We conducted a population-based cross-sectional survey in 8,042 South Indians above the age of 20 years. Following completion of a detailed medical history questionnaire, all participants underwent haemodynamic screening including brachial and central blood pressure, and PWV measurements using a high-fidelity applanation tonometry. The study included anthropometric measurements and fasting blood for total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL) and blood glucose (BG) levels. After the exclusion of people with previous history of diabetes, hypertension and dyslipidemia on drug therapy, 5,841 subjects (mean age 41.6 years; 58% women) constituted the study sample Results In an univariate analysis, PWV correlated positively with age, mean blood pressure (MAP), heart rate (HR), body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), body fat percent (BF%), TC, TG, LDL and BG levels (P <0.001) and negatively with HDL levels (P=0.005). In a multivariate regression analysis, majority of the PWV variability in the model was accounted for by MAP and age, (cumulative adjusted R2 change of 32.79% as compared to the total adjusted R2 change of 35.25%). However, BMI (β= 0.042; adjusted R2 change=2.83%; p<0.001) independently correlated with PWV and its contribution to the PWV variability was far more significant compared to LDL, BG and TG (cumulative adjusted R2 change=1.08%). Multivariate regression analysis using the WC, WHR, or BF% instead of the BMI continued to demonstrate a significant independent effect of obesity parameters on PWV. Conclusion: In a large a population-based cross-sectional survey the study demonstrates a positive, independent association between obesity parameters and increased arterial stiffness.

Purpose. To investigate the effect of uneventful cataract surgery on macular ganglion cell-inner plexiform layer (mGC-IPL) thickness in glaucoma patients.Methods. This retrospective study included 65 eyes of 65 subjects who underwent uneventful cataract surgery, including 13 glaucoma eyes and 52 normal eyes. Using spectral domain optical coherence tomography, the mGC-IPL thickness was measured and compared between glaucoma and normal eyes preoperatively as well as 1 month and 3 months postoperatively. Linear regression analysis was used to determine the factors associated with postoperative change in mGC-IPL thickness.Results. The mean mGC-IPL significantly increased in both groups 1 month and 3 months after surgery (allPvalues equal to or less than 0.001). The postoperative changes between groups were not significantly different (P=0.171). In the multivariate regression analysis, preoperative mGC-IPL thickness showed a significant association with the change of average mGC-IPL thickness 1 month and 3 months after surgery (allPvalues < 0.001).Conclusions. The mean mGC-IPL thickness was increased after cataract surgery, and the postoperative mGC-IPL thickness changes were associated with preoperative mGC-IPL thickness in both groups and axial length in normal eye. The effects of cataract surgery on mean mGC-IPL thickness were not different in glaucomatous and normal eyes.

Abstract Background The purpose of this study was to evaluate the ocular biometric parameters in adult cataract patients from China and create an anterior chamber depth (ACD) regression model. Methods The ocular biometric records of 28,709 right eyes of cataract surgery candidates who were treated at Aier Eye Hospitals in nine cities from 2018 to 2019 were retrospectively analyzed. All measurements were taken with IOLMaster 700. We included patients who were at least 40 years old and were diagnosed with cataract. Results The mean age of the patients was 68.6 ± 11.0 years. The mean values recorded were as follows: axial length (AL), 24.17 ± 2.47 mm; mean keratometry (Km) value, 44.26 ± 1.70 D; corneal astigmatism (CA), 1.06 ± 0.96 D; ACD, 3.02 ± 0.45 mm; lens thickness (LT), 4.52 ± 0.45 mm; central corneal thickness (CCT), 0.534 ± 0.04 mm; and white to white (WTW) corneal diameter, 11.64 ± 0.46 mm. ACD correlated positively with AL (Spearman coefficient, 0.544) and WTW (0.300), but negatively with LT (-0.660) and age (-0.285) (all P < 0.01). In the multivariate regression analysis of ACD, which included LT, AL, WTW, sex, Km, CCT, and age, there was a reasonable prediction with adjusted R2 = 0.641. Conclusions Cataract patients with longer AL and wider WTW have deeper ACD. With increasing age and lens thickening ACD becomes shallower. Based on the standardized coefficients of ACD multivariate regression analysis from the study, LT is the main factor that affects ACD, and is followed by AL.

BACKGROUND The diabetes disease burden in China is heavy, and mobile apps have a great potential for diabetes management. However, there is a lack of investigation of diabetes app use among Chinese diabetes patients and diabetologists. The perspectives and attitudes of diabetes patients and diabetologists regarding diabetes apps are also unclear. OBJECTIVE Our objectives were to investigate diabetes patients’ and diabetologists’ use, attitudes, and perspectives, as well as patients’ needs, with respect to diabetes apps to provide information regarding the optimal design of diabetes apps and the best strategies to promote their use. METHODS Diabetes patients and diabetologists across China were surveyed on the WeChat (Tencent Corp) network using Sojump (Changsha ran Xing InfoTech Ltd) from January 23, 2018, to July 30, 2018. In total, 2 survey links were initially sent to doctors from 46 Latent Autoimmune Diabetes of Adults Study collaborative hospitals in China in 25 major cities and were spread on their WeChat contacts network. We also published the patient survey link on 3 WeChat public accounts and requested diabetes patients to fill out questionnaires. A multivariate regression analysis was used to identify associations of demographic and basic disease information with app usage among adult patients. RESULTS Overall, 1276 individuals from 30 provincial regions responded to the patient survey; among them, the overall app awareness rate was 29.94% (382/1276) and usage was 15.44% (197/1276). The usage was higher among patients with type 1 diabetes (T1DM) than among patients with type 2 diabetes (T2DM; 108/473, 22.8% vs 79/733, 10.8%; P<.001). The multivariate regression analysis showed that diabetes type, age, education, family income, and location were associated with app use in adult patients (P<.05). The need for and selection of diabetes apps differed slightly between patients with T1DM and patients with T2DM. The reasons why patients discontinued the use of an app included limited time (59/197, 29.9%), complicated operations (50/197, 25.4%), ineffectiveness for glycemic control (48/197, 24.4%), and cost (38/197, 19.3%). Of the 608 responders to the diabetologist survey, 40.5% (246/608) recommended diabetes apps to patients and 25.2% (153/608) used diabetes apps to manage patients. The greatest obstacles to the diabetologists’ use of apps to manage diabetes patients include limited time (280/608, 46.1%), legal issues (129/608, 21.2%), patients’ distrust (108/608, 17.8%), and billing issues (66/608, 10.9%). CONCLUSIONS The awareness and use of diabetes apps in Chinese people with diabetes and the proportion of diabetologists using diabetes apps to manage patients are low. Designing apps targeting different patient needs and conducting high-quality randomized controlled trials will improve the effectiveness of the apps, provide evidence for patients to choose suitable apps, and be conducive to the promotion of app use.

Abstract Abstract 3804 Introduction: Hemostasis is maintained by a delicate balance between numerous activators and inhibitors. Present concept posits that mild bleeding phenotypes are multi-factorial and resulting from minor variations in numerous components of the system. Although natural anticoagulant protein deficiencies are the established causes of thrombotic disorders, their roles in bleeding diathesis have not been reported. Currently, hemorrhagic symptoms can be accurately quantified using the standardized questionnaire. We hypothesized that a weak effect of each factor on bleeding symptoms could be demonstrated, if we employed a sufficiently large sample size. Method: The adult subjects were recruited from Bangkok and nearby provinces as parts of health surveys/check-ups. Current pregnancy, known bleeding disorders and anti-platelet drug or anticoagulant uses were excluded. The modified questionnaire based on the validated MCMDM-1VWD form was applied with assistances by trained interviewers to assess bleeding symptoms. Von Willebrand factor (vWF) activity (Collagen binding activity) and free protein S levels were determined using ELISA methods. Protein C activity was measured using a chromogenic assay. Results: A total of 5,208 Thai individuals participated in the study. The mean (±SD) age was 44.3 (± 13.7) yrs, ranging from 15–99 years, and 2129 (40.9%) were male. The mean bleeding score was -0.28 (±1.14), ranging from -3 to 7. There were 38 (0.73%) high hemorrhagic scores (≥4). The scores were significantly lower in female than in male (-0.36 vs. -0.16, respectively). This discrepancy vanished after excluding scores on post-partum bleeding. Among women, 17.9% of them were taking female hormone. There was no different in vWF, protein C and protein S levels between women with and without estrogen uses. The bleeding scores were negatively correlated with age, vWF and protein C activities (γ= −0.23, −0.09, and −0.09, respectively, all p< 0.001) but not with protein S levels. If the items on dental and surgical procedures were omitted from the score calculation, the correlation between age and hemorrhagic scores was not found. Therefore, the sex and age differences in bleeding scores were likely due to higher probabilities of experiencing uneventful hemostatic challenges, which yielded negative scores, in healthy women and elderly. Using multivariate regression analysis, age (β= -0.22, p< 0.001), male sex (β= 0.08, p<0.001), high (> 150 U/ml) protein C levels (β= -0.04, p=0.003), high (> 150 U/ml) protein S levels (β= 0.04, p=0.005) and vWF activity below 30 IU/L (β= 0.03, p=0.021) were significantly associated with bleeding scores. A subgroup of 180 subjects (3.4%) showed low vWF activity (≤50 IU/L). In this group, the mean bleeding score (-0.16) was not different from that of the higher vWF group and only 2 individuals (0.04% of total population) had abnormal hemorrhagic scores (≥4) suggesting that there were other factors influencing bleeding severity in this subgroup. In a multivariate regression analysis, bleeding scores in the low vWF group were significantly correlated with protein S levels (β= 0.26, p= 0.003) and vWF activity below 30 IU/L (β= 0.15, p=0.046) but not with age, sex and protein C activity. Conclusion: Our population-based data revealed the relationships of vWF, protein C and protein S levels with hemorrhagic history. The negative correlation between protein C activity and bleeding is unexpected and needs further investigations. These findings may suggest the novel roles of natural anticoagulants in modifying bleeding symptoms. Disclosures: No relevant conflicts of interest to declare.

This study assesses the determinants of family planning methods use by Turkish married men in South East Anatolia. A descriptive and cross-sectional survey research design was used among 1,352 men aged 20 to 52 years who lived in South East Turkey. A pilot-tested questionnaire was used to collect data. Descriptive statistics, chi-square, and multivariate regression analysis were used. The rate of nonusage of contraceptive methods among the participants was 60.4%. Within the nonusers, 34.9% reported a religious prohibition and 9.4% had misconceptions about family planning. Chi-square analysis determined four factors that were significantly related to the men’s usage of contraception. These factors are the following: the men’s age, educational level, number of existing children, and their perception of their household income level. These four factors were also subjected to multivariate regression analysis, the results of which were used to compute odds ratios for each value of each factor indicating the likelihood for using contraception by men within each group. Male-specific family planning programs can make an important contribution to the overall efforts to improve the usage of contraceptives by men. It is important to note that family planning services and education programs related to family planning should be appropriate for men.

Purpose: The post–endovascular abdominal aortic aneurysm repair (EVAR) inflammatory response, which is very often associated with fever, has been ascribed to a wide range of proinflammatory mediators and operative events. The aim of this study was to evaluate the impact of such factors in the development of fever of noninfectious origin after elective EVAR. Materials and Methods: A retrospective analysis of prospectively collected data of patients treated with standard elective EVAR between February 2017 and December 2020 was undertaken. The database included patients’ demographics and comorbidities, as well as laboratory inflammatory markers (white blood cell count, neutrophils, and C-reactive protein [CRP]) and anatomical characteristics (sac diameter, inferior mesenteric artery [IMA] patency and diameter, number of patent lumbar arteries, internal iliac artery [IIA] patency or occlusion). Intraoperative details, such as type of stent graft material and IIA overstenting, were also analyzed. Patients with infectious postoperative complications or previously receiving systemic anti-inflammatory medication were excluded. Statistical analysis was performed by SPSS 22.0 for Windows software (IBM Corp, Armonk, New York). Results: From 332 patients treated with elective EVAR between 2017 and 2020, 268 patients (all men) were included in the analysis. The mean age was 72.1±7.5 years and the mean aneurysm diameter was 59.1±12.1 mm. Seventeen patients were excluded due to a known infection site. From the study cohort, 114 (42.5%) patients presented with fever. Multivariate regression analysis confirmed that the occlusion of IMA ≥5 mm (p<0.008) and higher CRP (p<0.001) were independent factors associated with postoperative fever. A subanalysis was performed only on patients with patent IMA before EVAR. In the multivariate regression analysis of this subgroup, IMA ≥5 mm (p=0.008), presence of dyslipidemia (p=0.037), and higher CRP (p<0.001) were related to fever. Conclusion: Occlusion of an existing wide (≥5 mm) and patent IMA prior to EVAR may contribute to the development of post-EVAR pyrexia. The CRP is a reliable marker for post-EVAR fever. Further prospective studies are needed to corroborate these findings.
